    [0001] TECHNICAL FIELD The present invention relates to the general technical field of pressure food cooking appliances, and in particular to household appliances of the type 5 pressure cookers intended to form an enclosure. cooker capable of increasing pressure to ensure steam cooking food vapor contained within it. The present invention more particularly relates to a food pressurized cooking apparatus comprising a tank, a lid, and a locking system. Pressurized food cooking appliances, particularly for domestic use, are well known. They generally comprise a metal tank on which is intended to be reported sealingly, via a flexible seal ring seal, a lid also metal, so as to constitute a cooking chamber capable of mounting in pressure . The lid is intended to be connected to the tank by means of locking means allowing the pressure cooker to evolve between a lid locking configuration relative to the tank, in which the cooking chamber is able to mount. in pressure, and an unlocking configuration in which the lid can be freely separated from the tank. Known devices are conventionally provided with a pressure regulating valve intended to maintain the pressure level prevailing in the cooking chamber at a set level. It is known to equip such a cooking appliance with different sensors for collecting information used to control various operating parameters of the appliance. It is for example known to have a temperature sensor on the lid of a pressure cooker so as to obtain an electric signal image of the temperature prevailing at the outlet of a steam leakage duct mounted downstream of the control valve 25 pressure equipping the device. The electrical output signal of this temperature sensor is used to trigger a timer. Pressurized cooking appliances are also known having a control member movably mounted on the cover between its different positions corresponding to different functional settings (for example a decompression position and different cooking positions respectively corresponding to different values). different pressure settings). The selector in question advantageously embeds a magnet for selectively exciting a plurality of sensors embedded in an electronic module mounted on the cover. Such an arrangement makes it possible to obtain an electrical signal representative of the position of the selector, in order to use this information to assist the user in the use of the apparatus, via an appropriate interface. Such pressure cooking appliances are generally satisfactory, but do not have certain disadvantages. In particular, the sensors referred to above are permanently (as long as they are electrically powered) in a detection state and can therefore deliver information in the form of electrical signals, even if the pressure cooker is obviously not operational. This can of course lead to a risk of malfunction of the pressure cooker resulting from the exploitation of erroneous information. In particular, the temperature sensor mentioned above can quite provide interpretable electrical signals even if the pressure cooker is absolutely not in a position to function, for example because the lid has not been attached and locked on the tank, which can lead to "lure" involuntarily associated electronic systems (timer or others). It is therefore necessary to use additional control means (electronic, software, mechanical ...) to deal with these dysfunctional situations, which can be disruptive for a normally informed user. The implementation of such additional means also complicates the construction of the pressure cooker and increases its manufacturing cost. In addition, the known sensor systems used in prior art pressure cookers are very often adapted to particular types of pressure cookers, which have in common point to implement a locking / unlocking system. jaws. On the other hand, such known sensor systems are little or not at all suitable for use on pressurized cooking appliances whose locking / unlocking system relies on a displacement (whether overall displacement or deformation) of the lid 3036938 3 such as bayonet locking systems, flexible cover or stirrup. The objects assigned to the invention therefore aim to remedy the various disadvantages listed above and to propose a new pressurized food cooking appliance 5 capable of delivering an information and / or control signal in a particularly simple manner, reliable and cheap. Another object of the invention is to provide a new pressure cooker whose design allows to control automatically, particularly simple and effective, that the lid is well reported and locked on the tank.
    [0002] Another object of the invention is to provide a novel, particularly compact and lightweight pressurized food cooking apparatus. Another object of the invention is to propose a new pressure cooking apparatus which makes it possible to provide, in a particularly simple and reliable manner, not only information as to the locked or unlocked state of the lid, but also information as to the beginning. from the cooking cycle to the operating pressure. Another object of the invention is to provide a new pressure cooker that is particularly ergonomic and easy to use, especially with one hand. Another object of the invention is to provide a novel pressure food cooking apparatus which has a high capacity to suggest in a natural and intuitive way its own use. Another object of the invention is to propose a new device for cooking food under pressure which provides a high level of safety of use.
    [0003] Another object of the invention is to provide a novel pressure food cooking apparatus which uses a particularly robust and compact lock control mechanism. Another object of the invention is to provide a novel pressure food cooking apparatus which is easy and convenient to store and wash in the dishwasher. The objects assigned to the invention are attained by means of a pressurized food cooking apparatus comprising a tank, a lid and a locking system, said apparatus being characterized in that it comprises a a cover subassembly which includes both said cover and a support attached to said cover so that said cover can move relative to said support between two positions respectively corresponding to an unlocking configuration and a locking configuration of said subset of lid, the lid subassembly and the bowl being adapted to be joined in at least one predetermined relative arrangement allowing said locking system to lock the lid to the bowl by moving the lid 15 relative to the holder in order to pass the subassembly. cover assembly from its unlocking configuration to its locking configuration, said subset of aperture comprising a first device and a second device which is capable, provided that said first and second devices are separated by a distance not exceeding a predetermined value, to influence the first device 20 so that the latter delivers in response an information and / or control signal, said support and cover respectively embodying one and the other of said first and second devices so that when said subset of cover is in lock configuration said first and second devices are separated by a distance not exceeding said predetermined value, and so that when said lid subassembly is in the unlocking configuration said first and second devices are separated by a distance that exceeds said predetermined value.

FIG. 3 illustrates, in a schematic perspective view, the Figure 1 apparatus with the detachable module of Figure 2 attached to the lid subassembly, which is in the unlocking configuration. - Figure 4 illustrates, in a schematic perspective view from above, the tank of the pressure cooking apparatus of Figures 1 and 3, said vessel being in this case provided with two side handles for handling and transport.

FIGS. 14 to 16 are views similar to those of FIGS. 9, 12 and 13, respectively, with the difference that the control member is in its retracted position corresponding to the locking of the cover and that the subassembly of FIG. lid is therefore in lock configuration. 5 - Figure 17 illustrates, in a schematic perspective view, a detail of embodiment of the lid subassembly, for displaying a portion of the control mechanism of the pivoting of the cover relative to the support. FIG. 18 illustrates, in a diagrammatic sectional view, a detailed embodiment of the apparatus of FIGS. 7 and 8, making it possible to visualize the way in which the temperature sensor is positioned relative to the pressure control valve when the lid subassembly is in lock configuration. As illustrated in the figures, the invention relates to a device 1 for cooking food under pressure, intended to ensure the cooking of different foods at a pressure level higher than atmospheric pressure, in the presence of steam, and for example steam. of water. Said steam is generated by heating, within the apparatus 1 and in the presence of food, a cooking liquid, for example an aqueous liquid. The apparatus 1 according to the invention is preferably intended for domestic use, it being understood however that the invention may also relate to professional or semiprofessional apparatus. The apparatus 1 according to the invention is designed to mount pressure 20 exclusively under the effect of a heating source (onboard or external), without external pressure supply. The apparatus 1 for cooking food under pressure is therefore a pressure cooker, preferably intended to be arranged on an independent cooking plate to heat the contents. The cooking apparatus 1 according to the invention comprises at least one bowl 2 forming a cooking vessel, intended to receive the food to be cooked and having in this case substantially a symmetry of revolution along a central vertical axis X-X ' which extends in a direction that is similar to the vertical direction when the apparatus 1 is in normal operation, that is to say rests on a horizontal plane. The tank 2 comprises a bottom 2A and an annular side wall 2B which rises between said bottom 2A and a free upper edge 2C, which is in this case circular in shape, and 3036938 8 which delimits an access opening to the 2. The conformation of this free upper edge 2C will be described in greater detail in the following, in relation to the locking means of the apparatus 1. Advantageously, and as illustrated in the figures, the apparatus of FIG. 1 comprises at least one 2D bowl handle which is fixed to said bowl 2, so as to protrude outwardly from the latter, and preferably two identical handles 2D, 2E fixed on the side wall 2B of the tank 2 so as to diametrically opposite to the central axis X-X '. The apparatus 1 according to the invention also comprises a lid 3 intended to be associated with the tank 2 and locked relative to the latter to form a cooking chamber capable of mounting in pressure, that is to say an enclosure sufficiently hermetic cooking to allow the increase in pressure of the apparatus 1. In order to obtain this hermetic, waterproof character, the apparatus 1 advantageously includes a seal (not shown), preferably formed by a flexible annular seal , elastomer for example, intended to be interposed between the lid 3 and the tank 2, to thereby prevent any uncontrolled leakage of steam and / or air between the inside of the enclosure and the outside. The lid 3 advantageously has a shape conjugate to that of the tank 2, for example a generally discoidal shape, which advantageously extends in a mean plane substantially parallel to the mean plane of extension of the bottom 2A of the tank 2 (this is that is, a substantially horizontal plane in this case) when it is attached and locked on the latter. In the embodiment illustrated in the figures, the cover 3 includes a discoid cover element 3A of shape and dimensions conjugated to those of the access opening delimited by the free upper edge 2C of the annular side wall 2B of the vessel 2 In this embodiment, the cover 3 also advantageously includes an annular belt 3B, for example of substantially cylindrical or frustoconical shape, which rises between a first circular edge 30B integral with the discoidal cover element 3A (in part). species at the periphery of the latter) and a second free circular edge 31B, which for example is itself extended by an end flange. As illustrated in the figures, the discoidal cover element 3A extends generally along a horizontal mean plane, that is to say in this case parallel to the mean extension plane of the bottom 2A of the tank 2 when the cover 3 is associated with the vessel 3036938 9 to form the cooking chamber, while the annular belt 3B extends substantially vertically, that is to say, parallel to the central axis X-X ', the end flange extending in turn substantially horizontally. This of course does not exclude that the discoid cover element 3A may be, as shown in the figures, slightly domed or curved locally, as is well known as such. In the embodiment illustrated in the figures, the annular belt 3B is formed by a falling edge which extends downwardly from the periphery of the discoid cover member 3A. In this embodiment, the lid 3 is intended to cap substantially adjust the top of the tank 2, so that the annular belt 3B 10 surrounds from the outside the top of the annular side wall 2B and the upper edge free 2C, while the discoid cover member 3A rests on the free edge 2C, by means of the seal interposed between the tank 2 and the lid 3. It is however perfectly possible that the annular belt 3B or alternatively intended to be inserted into the tank 2, so as to be surrounded by, and contained in, the tank 2, without departing from the scope of the invention. Regulating members 4 (described in greater detail below) and safety devices 6 are advantageously directly mounted on the cover 3. The apparatus 1 according to the invention also comprises a locking system designed to allow the enclosure to baking formed by the combination of the lid 3 and the tank 2 to be pressurized significantly (for example of the order of 100 kPa above atmospheric pressure) without the risk of the lid 3 escape under the effect the pressure prevailing within the enclosure. Preferably, and in accordance with the embodiment illustrated in the figures, the locking system equipping the device 1 is a bayonet locking system, designed to lock and unlock the lid 3 relatively to the tank 2 by pivoting the lid 3 relative to the tank 2, in this case said central vertical axis X-X '. The invention is however not limited to the implementation of a bayonet locking system, and the apparatus 1 may alternatively be equipped with a locking system of another type. For example, the locking system may be a locking system based on the radial displacement, relative to the cover 3, of a locking element, such as a jaw or segment, intended to cooperate with a conformation. complementary to the tank 2 (for example a rolled edge for a jaw locking system, or a light formed through the side wall 2A when it is a segment locking system). The locking element is thus mounted in this case between a locking position, in which each jaw encloses the lid and the rolled upper edge of the tank (or in which each segment penetrates the light formed in the chamber). lateral wall of the vessel) and on the other hand an unlocking position obtained by centrifugal radial displacement of the locking element from its locking position, in which the jaws are no longer in contact with the rolled edge of the tank (or in which the segments are extracted out of the light), which allows the user to freely disconnect the lid 3 of the tank 2. Such a locking system is described for example in EP-0 691 096 , EP-0 691 097 or EP-2 204 111 ,. Alternatively, the locking system may be based on the implementation of a re-entrant cover, for example a flexible re-entrant cover as described in EP-1 938 718. It is also possible that the locking system is a yoke locking system, based on the implementation of a transverse elongate member mounted to move vertically on the lid and whose free ends are intended to cooperate with mumps integral with the vessel. In general, the invention can implement any type of locking system, and preferably any locking system based on the relative displacement of the cover and a part carried by the cover (whether a stirrup, an arm carrying a jaw or a segment, a support to which a flexible cover is suspended, etc.). In a particularly preferred manner, the locking system is a bayonet locking system, making it possible to pass the apparatus 1 of a locking waiting configuration, in which the cover 3 is attached to the tank 2 and rests freely on the latter (FIGS. 1 and 3), to a locking configuration in which the tank 2 and the lid 3 interact to prevent their free separation (see FIGS. 7 and 8), and vice versa. Thus, in the embodiment illustrated in the figures, the apparatus 1 moves from its latching waiting configuration to its locking configuration by rotation of the lid 3 relative to the bowl 2 in a predetermined angular stroke around the latch. central axis X-X ', in a clockwise direction S1, and moves from its locking configuration to its latching waiting configuration by rotation of the lid 3 relative to the tank 2 according to said predetermined angular stroke around the central axis XX 'in a counter-clockwise direction S2 (alternatively, the direction S1 may be counter-clockwise and the direction S2 may be then hourly). The bayonet locking system of the cooking apparatus 1 advantageously comprises for this purpose first and second series of excrescences 7A-7J, 8A-8J which are secured respectively to the lid 3 and the bowl 2 and which are designed, in order to ensure the locking and unlocking of the lid 3 10 relative to the tank 2, to engage, respectively disengage, mutually by rotation of the cover 3 relative to the tank 2 about the central vertical axis XX 'according to said predetermined angular stroke. As is well known as such, the protuberances 7A-7J, 8A-8J of each of said first and second series are intended to cooperate in pairs, i.e. each protrusion of one of said 15 series is brought, by rotation of the lid 3 relative to the tank 2, to pass under a corresponding protrusion of the other series to lock the lid 3 relative to the tank 2. In the embodiment illustrated in the figures, the protuberances 7A-7J of the first series, integral with the cover 3, project radially inwardly of the cover 3, while the protuberances 8A-8J of the second series, integral with the vessel 2, project radially from the outer face of the the side wall 2B of the tank 2, towards the outside thereof. However, it is perfectly possible for the locking protrusions 7A-7J of the cover to protrude outwardly from the lid 3 and for the bowl protuberances 8A-8J to project radially towards the inside of the latter. In the example illustrated in the figures, the tank protuberances 8A-8J are formed by an annular flange projecting outwardly from the free upper edge 2C, whereby notches 9A-9J are formed through said annular flange. permitting the passage of said cover protuberances 7A-7J so that the portions of said annular flange extending between each notch 9A-9J form the respective tank ramps intended to cooperate with the cover protrusions 7A-7J which form the cover ramps. Thus, when the lid 3 is to cap the bowl 2, the protrusions 7A-7J cover can pass through the notches 9A-9J to 3036938 12 to be lower than the annular flange. The apparatus 1 is then in its pre-lock configuration (also referred to as the lock wait pattern), from which the lock pattern can be reached by simply rotating the lid 3 relative to the bowl 2 according to the vertical axis X-X ', 5 which has the effect of angularly shift the protrusions 7A-7J of the cover 3 and the notches 9A-9J of the annular rim, performing a locking type "bayonet". Preferably, in the embodiment illustrated in the figures, the cover protuberances 7A-7B are located on the annular belt 3B of the cover 3 at a distance from the second circular free edge 31B of said annular belt 3B, so that the 10 Annular belt 3B forms, below said volume elements, a self-centering skirt of lid 3 relative to vessel 2. In accordance with the invention, apparatus 1 comprises a lid subassembly (illustrated in isolation by the 5) which includes both the cover 3 and a support 10 attached to said cover 3, in this case permanently, so that the latter can move relative to said support 10 between two positions respectively corresponding to a configuration of FIG. unlocking and locking configuration of said lid subassembly. In the embodiment illustrated in the figures, the support 10 is attached to the cover 3 so that the latter can pivot relative to said support 10 between said two positions along the central vertical axis X-X '. The invention is however not limited to a rotational mounting of the cover 3 relative support 10. It is for example quite possible, in the case where the locking system is for example a locking system with flexible cover, that the cover 3 can move in translation relative to the support, as described in document EP-1 938 718. The pivot connection between the cover 3 and the support 10 can be made by any known means.
    [0005] In this case, the two positions between which the lid 3 can pivot relative to the support 10 are separated by a predetermined angular stroke corresponding to that required to pass the device 1 of its pre-locking configuration (waiting configuration 1) to its locking configuration illustrated for example in FIGS. 7 and 8. Advantageously, the support 10 is, in the embodiment illustrated in the figures, in the form of a cross-member, that is to say, a substantially elongate piece which extends diametrically on the cover 3 and which extends in this case at each of its ends by respective falling edges 10A, 10B. Preferably, the cross member in question comprises an enlarged central zone 100, for example of generally circular shape, extended on either side by a first arm 101 and a second arm 102 which themselves end respectively with said falling edges. 10A, 10B. The central portion 100 is advantageously provided with a central orifice 100A in which is intended to be threaded an axis 30 fixed on the lid 3, in the center of the latter, and around which the support 10 is intended to rotate along the vertical axis central X-X '. Preferably, the shaft 30 is provided with a threaded recess for cooperating with a screw 16 to fix the support 10 to the lid 3 while allowing the lid 3 to pivot about the axis 30. Advantageously, the support 10 comprises, in addition to the cross-shaped piece illustrated in Figure 10, a plate 17 which has a substantially circular shape substantially complementary to that of the central portion 100 of the cross member and which is intended to be interposed between said cross-member and the 15 upper face of the cover 3 to form a housing for accommodating at least in part a control mechanism. The cross member visible in Figure 10 is itself designed to be fixed (for example by means of several screws) permanently to the plate 17, to form with the latter a subset unitary cross member, monobloc, maintained on the cover 3 by means of the coupling 30 axis / screw 16, which coupling allows the pivoting of the cover 3 relative to the superstructure subassembly aforesaid forming the support 10. In addition, in the illustrated embodiment in the figures, the apparatus 1 comprises at least one guide pin 18, and preferably two guide pins 18, 19 arranged diametrically opposite relative to the central axis XX 'and permanently attached to the lid 3. Each of said guide pins 18, 19 is designed to slide in a complementary guide groove 18A, 19A formed in the support 10, for example towards each end of said support 10. The length of each groove 18A, 19A is adapted in this case to the angular travel of the cover 3 relative to the support 10. Each pin 18, 19 is further provided with an enlarged section head which cooperates with the edges of the corresponding groove 18A, 19A to retain vertically the support 10 and prevent it from moving vertically away from the cover 3.
    [0006] According to the invention, the lid subassembly and the bowl 2 are designed to be joined in at least one predetermined relative arrangement (illustrated for example in FIGS. 1 and 3) enabling said locking system to lock the lid 3. to the tank 2 by moving the cover 3 relative to the support 10 to move the lid subassembly from its unlocking configuration to its locking configuration. More specifically, the predetermined relative arrangement is in this case obtained by combining the tank 2 and the lid subassembly when the latter is in the unlocking configuration. In the embodiment illustrated in the figures, said predetermined relative arrangement allows the bayonet locking system to lock the lid 3 to the bowl 2 by pivoting the lid 3 relative to the support 10 along said central vertical axis X-X '. In other words, when the lid subassembly is in the unlocking configuration, the lid 3 and the support 10 are positioned relative to each other such that the docking of the support 10 on the tank 2 in a predetermined position, corresponding to said predetermined relative arrangement, allows the cover ramps 7A-7J to pass below the vessel ramps 8A-8J through the notches 9A-9J separating said vessel ramps 8A-8J, the sub-manifold cover assembly then capping the tank 2 in a waiting position, from which it will be sufficient to rotate the lid 3 relative to the tank 2 to lock the lid 3 relative to the tank 2. Thus, once the tank 2 and the lid subassembly in unlocking configuration joined according to the predetermined pre-locking arrangement shown in FIG. 1, it is sufficient to hold the support 10 in position relative to the tank 2 and to Rotate the lid 3 relative to the support 10 according to the predetermined angular stroke referred to above in order to bring the cover ramps in correspondence with the tank ramps, beneath the latter, thus locking the lid 3 relative to the tank 2. The apparatus 1 furthermore comprises a locking / unlocking control member 11, designed in this case to be manipulated by the user so as to enable the latter to control the locking system in order to be able to advantageously pass, by manual actuation of the the control member 11, the lid sub-assembly from its locking configuration to its unlocking configuration and vice versa, thereby controlling the passage of the apparatus 1 from its pre-configuration. locking (also referred to as a latch standby configuration - shown in Fig. 1) to its latch configuration (shown in Fig. 8), and inve rsement. The control member 11 is attached to the support 10, in this case permanently, so that it can be moved manually relative to the latter between locking positions (FIGS. 7 and 8) and unlocking positions (FIG. 1). and vice versa. In other words, the support 10 advantageously permanently embeds the control member 11, which nevertheless retains an ability of mobility relative to said support 10. Advantageously, the apparatus 1 also comprises a device for transforming the displacement of the control member 11 pivoting the cover 3 relative to the support 10 along the central vertical axis X-X ', so that said locking and unlocking positions of the control member 11 respectively correspond to said locking and unlocking configurations of the sub -cover assembly. The user can thus control the passage of the cover sub-assembly from its unlocking configuration to its locking configuration, and vice versa, by manual movement of the control member 11 relative to the support 10 between its unlocking positions and locking, and vice versa. The transformation device, which is particularly visible in FIGS. 9 and 12 to 17, is therefore designed to convert the movement of the control member 11 relative to the support 10 in rotary motion of the cover 3 relative to the same support 10, the species along said central vertical axis X-X ', so that the user can thus control the locking / unlocking by pivoting the cover 3 relative to the support 10 by simple manipulation of the control member 11, once the cover 3 attached to the tank 2 with the cover ramps 25 disposed below the tank ramps. Of course, the aforementioned conversion device is designed according to the nature of the displacement of the control member 11 relative to the support 10 and may implement any drive component (toothed wheel, cam, lever, rod, etc.. ) required. Advantageously, said control member 11 is pivotally mounted relative to said support 10 along a radial axis of pivot Y-Y 'which is perpendicular to the central vertical axis X-X', and is secant thereto. The control member 11 can thus be in the form of a rotary element of the handle, lever, joystick or handle type. However, it is quite possible for the control member 11 to be mounted more or less vertically. translation relatively support 10, and is for example in this case in the form of a sliding element such as a push button, a slider, etc. Advantageously, said transformation device comprises a gear reduction mechanism designed to drive the cover 3 in rotation about said central vertical axis XX 'in a path having a first predetermined angular amplitude a, in response to a rotation of said control member 11 about said axis. radial YY 'in a stroke having a second predetermined angular amplitude greater than said first predetermined angular amplitude a. For example, the control member 11 is adapted to pivot about said radial axis YY 'between a raised position (corresponding to the unlocking) and a folded position (corresponding to the lock) separated by a stroke having a predetermined angular amplitude of 6. about 90 °, while the cover 3 pivots relative to the support 10, in response to the approximately 90 ° angular displacement of the control member 11 relative to the support 10, in a stroke having a predetermined angular amplitude and about 15 °. According to the embodiment illustrated in the figures, the transformation device comprises a transmission part 20 mounted to move in translation in a horizontal plane perpendicular to said central vertical axis XX 'relative to said support 10. In this embodiment, the transformation device 20 comprises a mechanism for transforming the pivoting movement of the control member 11 relative to the support 10 in translational movement of said transmission member 20 relative to said support 10. For example, the transformation mechanism in question is formed by a cam 110 , 111 secured to the control member 11, said cam 110, 111 being provided with a pin which is received in a corresponding housing formed in the transmission part 20, so that the pivoting of the control member 11 causes the concomitant pivoting of the cam 110, 111, which then pushes the transmission piece 20 in the horizontal plane l perpendicular to the central vertical axis X-X '. Advantageously, the transformation device comprises, in accordance with the embodiment illustrated in the figures, at least one horizontal lever 21 pivotally mounted relative to the support 10 according to an eccentric vertical axis ZZ 'which is fixed with respect to said support 10, parallel to said axis vertical 3036938 17 central XX 'and located at a predetermined distance from the latter. Preferably, as illustrated in the figures, said horizontal lever 21 extends longitudinally between a first end 21A hinged to the cover 3 and a second end 21B hinged either to said control member 11 or to a transmission part (as for example the part 5 transmission member 20 mentioned above) which is part of the transformation device and which is driven in displacement relative to the support 10 by the control member 11, for example according to the embodiment described above. Preferably, said horizontal lever 21 is pivotally mounted relative to the support 10 at a pivot point located between said first end 21A and the second end 21B, so that the eccentric vertical axis ZZ 'passes through an area of the horizontal lever 21 which is located at a distance from both the first and second ends 21A, 21B. The articulation of the first end 21A relative to the lid 3 is for example made by means of a first pin 210A which is integral with the lid 3 so as to rise vertically from the latter. Said pin 210A is advantageously received in a first corresponding groove provided at the first end 21A of the horizontal lever 21, so that said first pin 210A can both slide and turn in the first groove in question. The conversion device also advantageously comprises a second pin 210B which is in this case secured to the transmission part 20 and embarked on the latter. Said second pin 210B is advantageously received in a second complementary groove formed at the second end 21B of the horizontal lever 21, so that said second pin 210B can both slide and pivot in the second groove in question. The displacement in rectilinear translation of the transmission part 20 in the horizontal plane is thus converted into rotation of the lever 21 around the eccentric vertical axis Z-Z ', which rotation is itself converted into a rotation of the cover 3 relatively. to the support 10 along the central vertical axis X-X '. The invention is however not absolutely limited to such a mechanism of motion transformation and it is for example perfectly conceivable to implement, in place of a lever system as illustrated, a rod system, cam or gear, or any other known system, without departing from the scope of the invention. Advantageously, and as illustrated in the figures, the control member 11 comprises a handle 11A intended to be manually actuated 3036938 18 so that it can be manually moved by a user between two preferably stable stop positions corresponding respectively to the locking and the locking. unlocking. In this preferred embodiment the control member 11 is therefore in the form of an arched, loop-shaped, arch form, advantageously designed so that it can be grasped firmly, preferably by hand, by a user. The invention is however not limited to the implementation of a loop to form the control member 11 and the latter may for example be constituted by a substantially rectilinear lever, or with a T-shaped profile, of L, a pommel shape, flared knob, etc., whose conformation preferably allows the user to lift the lid subassembly through it. Advantageously, as illustrated in the figures, the control member 11 is mounted pivotally relative to said support 10 between on the one hand an extended position (FIG. 1) which forms said unlocking position and in which said control member 11 projects vertically , in this case to the right of the lid 3 to the outside, and secondly a retracted position which forms said locking position and wherein said control member 11 is lowered to the lid 3. In its deployed position, the control member 11 advantageously extends in a mean direction substantially parallel to said central vertical axis X-X ', whereas in its retracted position it advantageously extends in a mean direction substantially perpendicular to said central vertical axis X-X as shown in the figures. Advantageously, the support 10 and the tank 2 are designed to interact, directly or indirectly, when the cover subassembly in the unlocking configuration and the tank 2 are joined in accordance with said predetermined relative arrangement, in order to substantially prevent the support 10 from ability to pivot relative to the vessel 2 (in this case along said central vertical axis X-X ') when the control member 11 is moved between its locking and unlocking positions (or vice versa). In other words, the meeting of the lid subassembly in the unlocking configuration and the tank 2 according to the predetermined relative arrangement (pre-locking arrangement) illustrated in FIG. 1 causes interlocking of the support 10 and of the tank 2 preventing in this case the support 10 to rotate along the central vertical axis XX 'while resting on the tank 30 2. This locking of the relative angular position of the support 10 and the tank 2 allows the support 10 to play the role of a stationary fixed frame relative to the tank 2 and relative to which the cover 3 can pivot about the central vertical axis XX 'in a predetermined angular stroke to move from an unlocked state (shown in FIG. Fig. 1) at a locked state (shown in Fig. 16). Preferably, said support 10 and tank 2 are respectively provided with complementary support conformations 12, 13 and 14, designed to cooperate by interlocking when the locking configuration of the lid subassembly and the tank 2 are joined according to said predetermined relative arrangement to form the cooking chamber (Figure 1). Said interlocking of the complementary support conformations 12, 13 and of vessel 14, 15 makes it possible to lock the relative angular position of the support 10 and of the vessel 2 in a horizontal plane, perpendicular to said central vertical axis X-X '. In the embodiment illustrated in the figures, the vessel 2 is provided with two tank conformations 14, 15 arranged diametrically opposite relative to the central vertical axis XX 'and fixed on the external face of the lateral wall 2B of the tank 2, while the support 10 has two complementary support conformations 12, 13 arranged diametrically opposite on the cover 3 relative to the central vertical axis X-X ', said support conformations 12, 13 being in this case disposed opposite the outer face of the annular belt 3B of the cover 3. However, it is quite possible, without departing from the scope of the invention, said support 10 and tank 2 are respectively provided a single support and vessel conformation, or even that the support 10 and tank 2 are provided, instead of respective conformations support and vessel intended to cooperate by interlocking, elem interlocking elements of another nature based on the implementation of force cooperation (by friction, clipping, meshing, magnetic attraction, etc.) sufficient to lock the relative angular position of the support 10 and of 2. Advantageously, each tank conformation 14, 15 forms a male element while each support conformation 12, 13 forms a complementary female element of said male element, said male element being advantageously intended to be inserted into said female element to establish a rotational lock connection 30 along the central vertical axis XX 'between the support 10 and the tank 2. Advantageously, said tank conformation 14, 15 is carried by said handle 2D, 2E tub. Thus, in the embodiment illustrated in the figures, each handle 2D, 2E, permanently fixed to the side wall 2B of the tank 2, embeds a tank conformation 14, 15 respectively, which is for example under the form of a rib forming a male element. A notch is advantageously provided in the free lower edge of each of said falling edges 10A, 10B of the support 10, to form a female element complementary to the rib preferably forming the male element. As illustrated in the figures, the lid subassembly comprises a first device 22 and a second device 23, the latter being capable, provided that said first and second devices 22, 23 are separated by a distance D n not exceeding a predetermined value, to exert an influence on the first device 22 so that said device 22 delivers in response an information signal and / or control, for example of electrical nature. In other words, the lid subassembly embodies, permanently or removably, said first and second devices 22, 23, which are designed to interact according to a predetermined functional connection as soon as they are sufficiently close to the one of the other, that is to say that as soon as the distance D mutually separating them is less than or equal to a threshold corresponding to said predetermined value referred to above. As illustrated in the figures, said support 10 and cover 3 respectively embark on each of said first and second devices 22, 23. This means that any one of said first and second devices 22, 23 is integral with the support 10 , while the other is secured to the lid 3, so that said first and second devices 22, 23 move relative to each other when the lid 3 moves relative to the support 10. In the illustrated example In the figures, the support 10 embeds the first device 22, while the lid 3 embeds the second device 23. It is however quite possible, without departing from the scope of the invention, that the support 10 rather embeds the second device 23 and the cover 3 then embeds the first device 22. In accordance with the invention, said support 10 and cover 3 respectively embark the one and the other of said first and second 22, 23 so that when said lid subassembly is in the locking configuration (shown in FIG. 8), said first and second devices 22, 23 are separated by a distance D which does not exceed said predetermined value, and so that when said lid subassembly is in the unlocking configuration (shown in FIG. 6) said first and second devices 22, 23 are this time instead separated by a distance D which exceeds said 5 predetermined value. In other words, the distance D separating said first and second devices 22, 23 varies between a first value that does not exceed said predetermined value (FIGS. 7 and 8) and a second value that exceeds said predetermined value (FIGS. 3). Thus, the invention is based on the idea of using a relative movement of the cover 3 and the support 10 to pass a first device 22, which is for example integral with the support 10, a first deactivated state or inactivable to a second activated or activatable state, by simple approximation of said first device 22 with a second device 23 which advantageously plays the role of activator element or exciter. This change of state of the first device in response to the influence exerted by the second device 23, made possible by bringing said first and second devices 22, 23 closer together, is used to cause the first device 22 to deliver data. a signal, that is to say a physical phenomenon of any nature (electrical, electromagnetic, sound, light ...) carrying information, in order to use this information directly to inform the user, either to control the operation of the device 1 itself or an external device (hob, computer terminal such as a smartphone or a touch pad ...). According to the invention, when the lid subassembly is in the locking configuration, the second device 23 finds itself positioned relative to the first device 22 so as to immediately exert an influence on the first device 22 so that the latter responds to said information and / or control signal, or to be able to exert said influence at a later time, for example when other conditions (such as reaching a predetermined value of pressure within the cooking chamber) will be united. The invention therefore uses the displacement of the cover 3 relative to the support 10 in order to develop, by means of the first device 22, an exploitable signal, either directly (if it is for example a light signal or a sound signal). information) (for example, an electrical signal intended for processing for the purpose of information or control). In the example illustrated in the figures, the first device 22 is carried by the support 10, that is to say it is attached to and against said support 10, while said second device 23 is carried by said cover 3, so that said second device 23 is directly attached to the outer face of said cover 3, for example on the discoid cover member 3A. Preferably, the first device 22 is formed by an independent module 24 (shown separately in FIG. 2) adapted to be releasably attached to said support 10, so that a user of the apparatus 1 can at will, and preferably without tools other than just his hands, attaching said independent module 24 to said support 10 and detaching it from the latter. To this end, said independent module 24 and support 10 are provided with respective complementary fastening means 25, 26 designed to cooperate in order to removably attach the independent module 24 to the support 10.
    [0007] This cooperation can be of any kind. For example, the complementary attachment means 25, 26 may be designed to cooperate by magnetic attraction, in which case the attachment means 26 associated with the support 10 is for example formed by a magnet while the independent module 24 embeds a ferromagnetic substance able to be attracted by the magnet in question. Preferably, the cooperation between the complementary attachment means 25, 26 is of a mechanical nature, as in the example illustrated in the figures, in which the independent module 24 is designed to be fixed on the support 10 by clipping, that is to say by interlocking by force of a male element forming in this case the attachment means 26 of the support and a female element forming in this case the attachment means 25 of the independent module 24 (or vice versa) . The complementary attachment means 25, 26 are advantageously designed to completely immobilize the first device 22 on the support 10, that is to say that they are designed to make a connection between the support 10 and the support 10. first device 22. It is however quite possible that the first device 22 is fixed to the support 10 with a mobility faculty, and / or that it is permanently attached, irremovable, the support 10.
    [0008] Advantageously, the apparatus 1 comprises at least one processing unit designed to exploit the information and / or control signal, in order to elaborate, from said signal which is preferably electrical in nature as mentioned above, a information intelligible by a user and / or a control instruction for controlling the operation of the apparatus 1 itself or an external device as mentioned above. In the embodiment illustrated in the figures, said processing unit is advantageously integrated in the independent module 24. However, it is quite possible for the processing unit to be distinct from said independent module 24, or even to be totally deported. of the apparatus 1, in which case the first device 22 10 is advantageously designed to communicate via a wired or wireless link (for example by radio waves) with the processing unit. In a preferred embodiment, the apparatus 1 comprises several processing units, one of which is embedded by the independent module 24 and the other on board by an external device advantageously formed by an ordiphone capable of communicating, for example by a link Bluetooth ®, with the independent module 24. In the embodiment illustrated in the figures, the processing unit is designed to exploit said information signal and / or control to develop information, the apparatus 1 comprising also a display means 27, such as a screen (for example an LCD screen, tactile or not), a display or a dial, which is connected to said processing unit by an appropriate functional link 20, wired or not, for to display said information and thus make it accessible and intelligible to the user of the apparatus 1. The invention is however not absolutely limited to the implementation of an independent module 24 equipped with a display means 27, and it is for example quite possible, without departing from the scope of the invention, the independent module 24 is devoid of any display means, the latter being offset on an independent external terminal (and for example formed by the screen of a ordiphone) which communicates by a wireless link with the independent module 24. Advantageously, said first device 22 includes a sensor 22A designed to develop said information and / or control signal from a physical magnitude value that the distance D between said first and second devices 22, 23 is capable of varying. More precisely, the sensor 22A is designed to measure a physical quantity in a zone of the predetermined space, preferably corresponding to the position of the sensor 22A in question. When the distance D between said first and second devices 22, 23 exceeds said predetermined value, the second device 23 5 is too far from the sensor 22A so that the physical quantity measured by said sensor can vary significantly. Conversely, when the first and second devices 22, 23 are brought closer to the point that the distance D which separates them does not exceed said predetermined value, the second device 23 is then capable of varying said physical quantity sufficiently significantly. in the detection zone of the sensor 22A for the latter to be able to elaborate said information and / or control signal. Preferably, said sensor 22A is a temperature sensor, while said second device 23 comprises an orifice 23A formed through the cover 3 to allow the temperature sensor 22A to be accessed, when said lid sub-assembly 15 is located. in the locking configuration, at the temperature prevailing within the apparatus 1, or an image thereof. This therefore means that, according to this preferred embodiment, the temperature sensor 22A is designed to elaborate said information and / or control signal from a temperature value that the distance between the sensor 22A and the orifice 23A provided through the cover 3 is capable of varying. Thus, when the lid subassembly is in the unlocking configuration, the temperature sensor 22A is too far from the orifice 23A for the temperature value measured by the sensor 22A to be influenced, even temporarily, significantly . In contrast, when the lid subassembly is in the latching configuration, the sensor 22A is sufficiently close to the orifice 23A that the temperature value it measures is directly a function of the temperature in the appliance. 1, that is to say prevailing within the cooking chamber formed by the lid 3 and the tank 2. Advantageously, said second device 23 forms a pressure regulating member 4 designed to prevent the pressure prevailing at the Within the apparatus 1 exceeds a predetermined set value, called "operating pressure", which exceeds the atmospheric pressure by a value which is for example between substantially 10 and 120 kPa, and which is preferably order of 100 kPa. The general operating principle of such a pressure regulating means is well known as such. Advantageously, said pressure regulating member includes a valve associated with said orifice 23A formed through the cover 3, said valve including itself a shutter 40 movable between a closed position, in which it prevents the vapor contained within the apparatus 1 to escape from the apparatus 1, that is to say in this case out of the cooking chamber, through the orifice 23 A, and an open position, 10 in which it allows the vapor contained within the apparatus 1 to escape out of the latter through the orifice 23A and according to a predetermined escape path. For example, as illustrated in the figures, the valve forming in this case the pressure regulating member 4 comprises a valve seat 41 which is in the form of a substantially tubular duct terminated at the orifice 23A and s' Raising substantially vertically, along an axis W-W ', to a free upper end that the shutter 40 closes or release depending on the pressure level prevailing within the cooking chamber. For example, the valve forming the pressure regulating member 4 includes a biasing means designed to exert a restoring force on the shutter 40, in order to keep the shutter 40 in its closed position as long as the pressure level prevailing within the cooking chamber is less than or equal to a predetermined level P0, corresponding to the operating pressure. The return means is designed so that as soon as the pressure prevailing within the cooking chamber exceeds the operating pressure P0, the steam exerts on the shutter 40 a driving force which is sufficient to overcome the restoring force and to discard the shutter 40 of the seat 41, to allow the steam contained in the cooking chamber to escape through the orifice 23A and the seat 41 to the outside. The return force in question may be for example exerted by a spring or simply by the weight of the shutter 40. Preferably, said valve is provided with a steam channeling member designed to impart to the steam s' escaping from the apparatus a substantially vertical exhaust path from bottom to top. In the example illustrated in the figures, the pipe member in question is formed by the seat 41, through which the steam escapes along an upward vertical trajectory, parallel to the axis WW '(itself parallel to the central vertical axis X-X ') when the shutter 40 is pushed into its open position. Advantageously, said temperature sensor 22A is designed to be on said steam escape path, when said lid subassembly is in a locking configuration, to determine the temperature of the steam at its exit from the Apparatus 1. Thus, in the embodiment illustrated in the figures, the temperature sensor 22A is intended to overhang said valve forming the pressure regulating member 4, when said lid subassembly is in locking configuration, so that the temperature sensor 22A is then on the symmetry axis WW 'of the seat 41, vertically and above the orifice 23A of the seat 41. On the contrary, when the lid subassembly is in the unlocking configuration (see FIG. 3), the temperature sensor 22A is angularly offset relative to said axis W-W ', so that it substantially does not cross the escape trajectory steam and is therefore not able to reliably determine the temperature of the steam at the outlet of the valve. Preferably, in order to further improve the reliability of the measurement, the steam channeling member comprises not only said seat 41, upstream of the movable shutter 40, but also a downstream channeling member 42, which has substantially a tubular shape and extends substantially upwardly from the upper end of the seat 41. Thus, when the lid subassembly is in the locking configuration, the temperature sensor 22A is itself perfectly positioned to detect at best any temperature variation that would be due to steam escaping through the valve. Advantageously, the apparatus 1 comprises a timer operatively connected to said temperature sensor 22A, which is adapted to detect a rise in temperature following a steam escape resulting from the passage of the shutter 40 in the open position, and to transmit in return a trigger signal of said timer. Thus, the temperature information collected by the sensor 22A is advantageously used by said processing unit to trigger the counting of a cooking time by a timer functionally connected to the sensor 22A. The processing unit is, for example, designed to detect the significant variation in temperature resulting from the exhaust of the very first jet of steam when the predetermined pressure PO has just been exceeded for the first time, in order to trigger at this instant the counting of the cooking time by the timer, in accordance, for example, with teaching of the document EP-1 458 268. The timer in question is advantageously embedded in the independent module 24, which is provided with control means (for example buttons) allowing a user to set the cooking time counted by the timer to the value of his choice, the screen 27 can display the value in question and the count of this value when the time comes.
    [0009] In order not to disturb the temperature measurement by the sensor 22A, said valve forming the pressure regulating member 4 advantageously has, in the vertical direction W-W ', an overall height H which is substantially invariable, in order not to not altering the distance vertically separating the top of the valve (corresponding in this case to the top of the downstream piping member 42) from the sensor 22A, when the lid subassembly is in a locking configuration. In order to further improve the temperature measurement accuracy, the first device 22 advantageously comprises an annular element 22B delimiting an interior space 22C (see FIG. 2) which is surrounded by said annular element 22B and which accommodates said temperature sensor 22A, in order to protect the latter from possible drafts which could disturb the measurement, and to limit the lateral loss of steam. The annular element 22B also makes it possible to protect the temperature sensor 22B against possible shocks (in the event of a fall, for example). The annular element 22B thus advantageously forms a loop which extends substantially in a horizontal mean plane perpendicular to the central vertical axis X-X ', the sensor 22A forming a protrusion which extends inwardly of said loop 25 to the center of the latter, so that the active portion of said sensor 22A is found substantially in the center of said loop formed by the annular element 22B. As illustrated in the figures, when the lid subassembly is in the locking configuration, the axis of symmetry of the orifice 23A passes through said center of said loop, and therefore by the sensor 22A, and more specifically by the active part of this last.
    [0010] Advantageously, as illustrated in the figures, the first device 22 comprises a main body 220 (see FIG. 2) which carries said temperature sensor 22A and annular element 22B so that they protrude laterally from said main body 220, at the door on the overhang 3. In this preferred embodiment, the main body 220 accommodates a display means 27 (for example an LCD screen on its upper face) as well as a timer which can be parameterized by means of control buttons also carried by the main body 220. An independent module 24 comprising a temperature sensor 22A and an annular element 22B delimiting an interior space 22C which is surrounded by said annular element 22B and which accommodates said temperature sensor 10 22A, as illustrated in Figure 2 for example, also constitutes as such an independent invention. Of course, the invention is not limited to the implementation of a sensor 22A which is a temperature sensor. Alternatively, the sensor 22A may for example be a magnetic sensor, in which case the second device 23 advantageously incorporates a magnetic element designed to excite the magnetic sensor in question when the distance D separating said first and second devices 22, 23 does not exceed said predetermined value, for said sensor 22A to respond in response to said information and / or control signal. In this case, the first and second devices 22, 23 are designed to interact magnetically when the lid subset is in the latching configuration, which magnetic interaction is advantageously a remote interaction. For example, the sensor 22A can be constituted in this case by a magneto-resistive sensor, for example of C-MOS type, while the magnetic element comprises a magnet, for example a permanent magnet. It is also possible, in an alternative embodiment, that the sensor 22A is a contact sensor, in which case said second device 23 advantageously incorporates an actuator intended to come into contact with said sensor 22A, when the lid subassembly is in the locking configuration, in order to actuate said sensor 22A, in this case in contact with the latter, so that said sensor 22A responds in response to said information signal and / or control. In this alternative embodiment, the first device 22 is, for example, provided with a switch forming the sensor 22A, said second device 23 being designed to press said switch when the lid subassembly passes into a locking configuration. , thereby to switch the switch in question from a deactivated state to an activated state. Ultimately, the invention is absolutely not limited to a specific interaction between said first and second devices 22, 23, this interaction being electrical, thermal, optical, magnetic ... the essential being that the movement of the cover 3 relative to the support 10 is used to obtain an information signal and / or control. Preferably, the apparatus 1 comprises an opening security means 5 distinct from said first and second devices and capable of changing, under the effect of the pressure level 10 prevailing in the apparatus 1, between a release configuration , in which it allows the unlocking of the lid 3 relative to the tank 2, and a locking position, in which it prevents the unlocking of the lid 3 relative to the tank 2. For this purpose, said security means 5 advantageously comprises an element mobile 5A slidably mounted on the cover 3, and in this case vertical sliding in a sliding direction parallel to the central vertical axis X-X ', between a high position (stop) in which it is capable of cooperate with a complementary blocking element 5B carried by the support 10, in order to block the displacement of the cover 3 relative to the support 10, and a low position (abutment) in which it does not interfere with the complementary element 5B, thus permitting the displacement of the lid 3 relative to the support 10. As can be seen in particular from FIG. 12, the movable element 5A is advantageously formed by a finger intended to slide vertically from a tube terminated to a leakage orifice formed through the lid 3, so that in the high position the finger comes to seal hermetically the leakage orifice, while in the low position the steam is allowed to leak by the orifice in question. Complementary element 5B is preferably formed by a part having a stop surface 50B and a through hole 51 B. As long as the cover is in its unlocking position relative to support 10, the surface of 50B lock is located at the right of the movable member 5A, on the sliding path of the latter, to prevent it from reaching its high position and thus maintain a communication between the inside of the chamber 30 of cooking with the outside, preventing any significant rise in pressure of the enclosure. On the contrary, when the lid 3 reaches its locking position, by pivoting relative to the support 10 according to the predetermined angular stroke mentioned above, the movable element 5 is then found at the right of the opening 51 B, which allows the element mobile 5A to achieve, under the effect of the driving force exerted by the rise in pressure within the cooking chamber, its upper sealing position. Once in the high position, the movable member 5A is surrounded by the edges of the orifice 51 B, which prevents any pivoting of the cover 3 relative to the support 10 in the unlocking direction. The operation of the cooking apparatus 1 illustrated in the figures will now be briefly described. The user first fills the tank 2 illustrated in Figure 4 of food to be cooked, possibly positioning the food away from the bottom of the tank 2, in a perforated cooking basket. The user then grabs the lid subassembly (shown in FIG. 5) by the handle 11A to lift the said subassembly with a view to bringing it back to the tank 2 in order to close the latter. The user thus assembles the lid sub-assembly in the unlocking configuration and the tank 2 according to the predetermined relative arrangement illustrated in particular in FIG. 1. In this configuration, the temperature sensor 22A and the axis WW 'of the Valve are angularly offset, as shown in FIG. 3. In this arrangement, the sensor 22A is not able to correctly detect the temperature variation corresponding to the exhaust of the first steam fumaroles when the set pressure PO is reached. . Then the user folds the loop 11A in an angular stroke i3 of about 90 °, until reaching a folded abutment position illustrated in particular in Figures 7 and 8. This movement of the handle 11A from its deployed position to its The folded position causes the cover 3 to pivot relative to the support 10 by an angle α of about 15 °, allowing the cover ramps to match under the vessel ramps in a locking configuration to allow pressure build-up. The pivoting of the cover 3 relative to the support 10 simultaneously causes the displacement of the valve relative to the support 10 and to the sensor 22A, so as to bring said valve under said sensor 22A, the latter then being in the exhaust path of the steam . The cooking cycle can then begin. As soon as the pressure within the cooking chamber 3036938 31 reaches the setpoint value P0, the steam escapes for the first time through the outlet duct of the valve, formed by the seat 41 and the downstream channeling member. 42, thus sweeping the sensor 22A which then detects this sudden rise in temperature and delivers in return a timer control signal embedded in the independent module 24, which in this case also the temperature sensor 22A. At the end of the cooking cycle, and once the pressure within the chamber has fallen back to a predetermined safety level, the user only has to raise the handle 11A to rotate the cover 3 relative to the support 10 in the opposite direction and thus disengage the tank and lid ramps, allowing the separation of the lid 3 and the tank 2.
