    [0001] The present invention relates to the general technical field of apparatus for cooking food under pressure, and in particular to domestic appliances of the pressure cooker type, comprising a tank and a pressure vessel. cover intended to be attached and locked on the tank in a sealed manner by locking means to form a substantially sealed cooking chamber during cooking, such devices being intended to ensure cooking under pressure of steam food contained in the enclosure Cooking.
    [0002] The present invention more particularly relates to an apparatus for cooking food under pressure comprising at least: - a circular tank and a circular lid intended to be brought into contact with the tank to form a substantially sealed cooking chamber with the aid of a sealing means interposed between the tank and the lid, - locking means arranged on the tank and the lid and forming tank ramps and cover ramps which are intended to cooperate together by relative rotation of the tank and the lid so that the cover ramps come under the tank ramps to ensure the lid lock on the tank.
    [0003] Pressure cooking appliances are already known and they comprise a tank, generally metal, to which is attached in a sealed manner, for example by means of a deformable seal, a lid, generally metal, so as to constitute a substantially sealed cooking chamber. The lid is intended to be connected to the tank by means of a locking mechanism capable of occupying at least one locking position of the lid on the tank and at least one unlocking position in which the lid can be removed. of the tank.
    [0004] There are different types of locking mechanisms well known in the prior art, and in particular four general locking concepts are used to ensure a strong connection between the tank and the lid to withstand the pressure in the tank during cooking. .
    [0005] Thus, for example, there are known devices for cooking pressurized food equipped with a locking mechanism called "stirrup" which comprise a stirrup rotatably mounted on the lid and coming to lock, after radial sliding of the lid on the tank , in eyelets integral with the upper edge of the tank. Pressurized food cooking appliances equipped with a locking mechanism known as "with a retracting lid" are also known, the lid being able to be of the oval or flexible type so as to be able to be inserted in or inside the bowl of in order to come into sealed support against the folded upper rim of the tank, thereby ensuring the mechanical connection locked between the tank and the lid via a connection between the bowl and lid handles. The concept of the return lid with flexible cover is associated with a lever and a stirrup coming to bear on the rim of the tank. The concept of oval shaped oval cover is also associated with a lever and a stirrup coming to bear on the tank rim. The concept of oval-shaped oval cover can also be associated with a spring blade bearing at the extreme end of the long bowl handle and on the edge of the tank. Pressurized food cooking appliances equipped with a "jaw or segment" locking mechanism including jaws or segments mounted to move or slide radially on the lid to come respectively, or to enclose the rim, are also known. top of the tank or pass through holes in the tank to lock the device. Finally, there are known pressure food cooking appliances equipped with a locking mechanism called "bayonet" formed of tank and lid ramps intended to cooperate with each other after rotation of the cover to come into sliding contact and ensure the connection retaining mechanism between the tank and the cover providing locking.
    [0006] Each of the mechanisms mentioned above has advantages and disadvantages recognized and identified such as the greater or lesser weight of the device linked to the locking mechanism equipping it, the more or less good ergonomics handling and locking or unlocking, or still more or less high level of security that it is likely to provide, or the greater or less ease of manufacture and finally the cost of manufacture resulting from the addition of multiple factors. The types of locking mechanisms identified above also have a greater or lesser capacity to suggest in a natural or intuitive manner the operation of the locking or unlocking mechanism according to necessary handling operations (affordance). It is therefore an object of the invention to provide a novel type of locking mechanism for steam pressurized food cooking apparatus which generally has more advantages and fewer disadvantages than conventional apparatus of the art. earlier identified above. The objects assigned to the invention thus generally aim to provide a pressurized food cooking appliance comprising a new locking or unlocking mechanism which is more efficient than the conventional prior art apparatuses mentioned above, and in particular which makes it possible to obtain a particularly light cooking appliance of a high level of safety, easy handling and having good affordance properties. Another object of the invention is to propose a new pressure food cooking appliance making it possible to optimize the quantity of material used, in particular by using reduced metal thicknesses without affecting the high level of safety. Another object of the invention is to propose a new device for cooking food under pressure to facilitate the ergonomics of the locking or unlocking operation.
    [0007] Another object of the invention is also to propose a new device for cooking food under pressure that can be manufactured in a simple manner while being robust and handling particularly easy and intuitive for the user. Another object of the invention is also to provide a pressurized food cooking appliance whose locking or unlocking operations are particularly well assimilated in a natural way by the user. The objects assigned to the invention also aim at proposing a new method of manufacturing locking means arranged on the tank and the lid of a pressure food cooking appliance which is particularly simple and economical to produce by reducing the assembly operations. Another object of the invention is to provide a novel method of manufacturing locking means disposed on the vessel and the lid of a pressure food cooking apparatus for using a proven method of manufacture. The objects assigned to the invention are achieved by means of a pressurized food cooking appliance comprising at least: a circular vat and a circular lid intended to be placed in abutment on the vat to form an enclosure substantially sealed cooking means by means of a sealing means interposed between the tank and the lid, - locking means arranged on the tank and the lid and forming tank ramps and cover ramps which are intended to cooperate together by relative rotation of the tank and lid so that the cover ramps come under the tank ramps to ensure the locking of the lid on the tank, said apparatus being characterized in that - the tank being delimited by an upper edge from which the vessel wall extends, the vessel ramps are disposed below said upper edge from a distance "d1" of said upper edge, - the lid is delimited by an outer bearing edge continuing with a cylindrical belt of dimension adjusted to that of the tank in order to come into contact with the wall of the tank when the lid is placed in support in or on the vessel by its outer bearing edge, the cover ramps being disposed on said cylindrical belt at a distance "d2" from the outer bearing edge, the distances d1 and d2 being such that they make it possible to cooperate the tank ramps; and the cover ramps between them when the lid is placed in abutment on the tank, the lid ramps being intended to pass under the tank ramps to bear sliding against the tank ramps when rotating relative of the lid inside the tank thus ensuring the locking. The objects assigned to the invention are also achieved by means of a method of manufacturing locking means arranged on the tank and the lid of a pressurized food cooking appliance and forming tank ramps and cover ramps which are intended to cooperate together by setting relative rotation of the tank and the lid so that the cover ramps come under the tank ramps in order to ensure the locking of the lid on the tank, characterized in that: said tank ramps and cover ramps are made of extra thickness from the wall of the vessel and / or the cover of the cover by adding material or material deformation. Other features and advantages of the invention will appear and will appear in more detail on reading the description given below, with reference to the accompanying drawings, given by way of illustrative and non-limiting examples, in which: FIG. 1 illustrates in a schematic perspective view an embodiment of a lid of a pressurized food cooking appliance according to the invention, the lid being provided with cover ramps. - Figure 2 illustrates in a schematic perspective view, a tank of a device 25 for cooking food under pressure according to the invention, said tank being provided with tank ramps formed in its wall. - Figure 3 illustrates, in a partial cross-sectional view, the position of the lid and the tank of a pressure food cooking appliance according to the invention in the locking position. - Figure 4 illustrates in a general perspective side view, a pressurized food cooking appliance according to the invention with a lid positioned above the tank in anticipation of docking and future locking. FIG. 5 is a partially perspective view from above of the respective positions of the tank and lid of a pressurized food cooking appliance according to the invention illustrated in FIG. 4. FIG. according to a perspective view partially from above, the support position of the lid on the tank of a pressurized food cooking appliance according to the invention, before locking. FIG. 7 illustrates, in a view similar to that of FIGS. 5 and 6, the position of the lid in its locking position on the tank of a pressurized food cooking appliance according to the invention after rotation from 6. As illustrated in the figures, the invention relates to a cooking apparatus 1 for food under steam pressure, preferably for domestic use, designed for cooking food in the presence of steam, which is generated by heating, within the apparatus and in the presence of food, a cooking liquid for example an aqueous liquid. As illustrated only for information, the cooking apparatus 1 comprises, in known manner, a circular vessel 3 and a circular lid 4 intended to be placed in abutment on the vessel 3 to form a cooking enclosure that is substantially watertight. using a sealing means 5, for example an annular seal with or without lips, interposed between the vessel 3 and the cover 4. In this way, it is possible to realize a sealed cooking chamber capable of increasing pressure when is subjected to the influence of a heating source (onboard or external) up to a predetermined pressure level for cooking food under pressure. In known manner, the cooking apparatus 1 according to the invention is provided with one or more control valves and / or safety (not shown in the figures) to ensure safety and maintain pressure inside the enclosure at the desired operating pressure level. As illustrated, the tank 3 is provided with a bottom 6, for example a cylindrical disk, capable of diffusing heat and from which the wall 7 of the tank 3 is raised, thus forming a circular wall delimited at its end. upper by an upper edge 8 also circular. The apparatus also comprises a lid 4, of cylindrical shape and of appropriate dimensions to be able to be attached to the tank 4. In a known manner, the tank 3 and the lid 4 are made from a metallic material, such as the stainless steel, or alternatively from an aluminum material, tripply material, the inner surface of the vessel 3 can be coated with ceramic materials, PTFE, enamel, lacquer or any other equivalent coating providing a anti adhesive and / or decorative effect. In general, the pressurized food cooking appliance according to the invention also comprises a locking mechanism formed of locking means 10, 11 disposed respectively on the bowl 3 and the lid 4 and forming tank ramps. and cover ramps 11 which are intended to cooperate together by relative rotation of the vessel 3 and the cover 4 so that the cover ramps 11 come under the tank ramps 10 to ensure the locking of the cover 4 on the 3. Thus, the locking means 10, 11 can maintain the lid 4 on the tank 3 to ensure a strong connection between the tank 3 and the lid 4 of the pressure cooker to withstand the internal pressure in the enclosure cooking resulting from the cooking of foods under pressure of steam.
    [0008] According to a combination of important features of the invention: the tank 3 is delimited by an upper edge 8 from which the tank wall 7 extends, the tank ramps 10 are arranged under the said upper edge 8 from a distance d1 from said upper edge 8, the cover 4 is delimited by an outer bearing edge 12 continuing with a cylindrical belt of dimension adjusted to that of the vessel 3 so as to come into fitted contact with the wall 7 of the vessel when the cover 4 is placed in support in or on the vessel 3 by its outer bearing edge 12 ', the ramps 11 of the cover 4 being disposed on said cylindrical belt 14 at a distance d2 from the outer bearing edge 12 , the distances d1 and d2 being such that they make it possible to make the tank ramps 10 and the cover ramps 11 cooperate with each other when the lid 4 is placed in abutment on the tank 3, the lid ramps 11 being for pass under the vessel ramps 10 come in sliding contact against the vessel ramps 10 upon relative rotation of the cover 4 inside the vessel 3 thus ensuring the locking. Thanks to these characteristics, a bayonet locking mechanism is thus provided which provides a strong tank / lid connection, the tank ramps 10 and the lid ramps 11 being provided at a distance from the respective upper limits of the tank 3 and the lid 4 to provide a circular zone or interface completely devoid of ramps 10, 11 thus allowing the introduction of the lid 4 inside the vessel 3 and the positioning of the tank ramps 10 and lid ramps 11 at a level below said circular area or interface.
    [0009] In general, the lid 4 may thus be a lid having a re-entrant portion, as illustrated, or a lid covering the bowl (not shown). This arrangement makes it easier to close and lock the device because the operation of placing, inserting the lid 4 within the vessel 3 and then rotating, for example in a clockwise direction, lid 4 and finally locking are sequences of operations that the user can achieve with a direct visual apprehension particularly directly appreciate the respective positions of the tank ramps 10 and cover ramps 11. In conventional bayonet systems, the user makes the docking of the lid on the tank "blind" because the overflowing position of the lid completely masks the tank.
    [0010] According to the alternative embodiment illustrated in the figures, the cooking apparatus 1 has an outer bearing edge 12 which continues with a reentrant portion 13 forming the cylindrical belt, said reentrant portion 13 being of dimension adjusted but less than that of the tank 3 so that it can be introduced into the tank so that the reentrant portion 13 comes into fitted contact during the introduction of the lid 4 with the wall 7 of the tank, and in particular with its inner surface.
    [0011] According to an alternative alternative construction, not shown in the figures, the cooking apparatus 1 may have an outer bearing edge 12 which continues with a portion capping the outside of the tank 3 and forming the cylindrical belt, said styling portion the outside of the tank 3 being of dimension adjusted but greater than that of the tank 3 in order to cap the outside of the tank 3 so that the portion covering the outside of the tank comes into contact with the outside of the wall 7 during the introduction of the cover 4. According to this alternative variant, the cover ramps 11 extend substantially radially from the periphery of the reentrant portion 13 towards the inside of the apparatus 1 and the Ramps 10 extend substantially radially from the wall periphery 7 of the tank towards the outside of the apparatus 1. In a conventional manner, the tank ramps 10 and the cover ramps 11 are presented or in the form of parallelepipedal metal parts which are elongated and of small width and thickness, that is to say generally longer than wide and thick.
    [0012] In a particularly advantageous manner, and as illustrated in the variant shown in the figures, the cover ramps 11 extend substantially radially from the periphery of the reentrant portion 13 towards the outside of the apparatus. Thus, tank ramps 10 are made whose width is directed in a centripetal direction towards the center of the apparatus while the width of the cover ramps 11 is directed in a centrifugal direction thus tending to move away from the center of the apparatus. device or axis of revolution XX 'of the device. The width of the tank ramps 10 and the cover ramps 11 may for example be of the order of 5 mm and between 2 mm and 10 mm.
    [0013] As illustrated in the figures, the tank ramps 10 and the cover ramps 11 are substantially rectilinear and have an angular inclination alpha (a) with respect to the extension plane P of the bottom 6 of the tank 3 so as to allow the setting in compression of the cover 4 on the vessel 3 during the relative rotation of the cover 4 on the vessel 3.
    [0014] This arrangement thus allows a progressive compression of the lid 4 which is thus progressively closer to the bottom 6 during its rotation due to the angular inclination alpha (a) of the tank ramps 10 and 11 cover ramps. schematically illustrated in FIG. 2, the angular inclination alpha (a) corresponds to the angle alpha (a) formed by the median and longitudinal plane M of the tank ramps 10 or cover ramps 11 with the extension plane P of the tank bottom 6 or a parallel plane P '. The alpha angular inclination (a) of the tank ramps 10 and lid ramps 11 is substantially identical for all the tank ramps 10 and the lid ramps 11. The angular inclination alpha (a) thus makes it possible to define for each tank ramp 10 15 or cover ramp 11 a high end 10H or 11H further from the bottom 6 than the lower ends 10B or 11B of each tank ramp 10 or cover ramp 11. As an alternative variant (not shown in FIGS. ), it is possible to provide for tank ramps 10 and cover ramps 11 which extend horizontally in consideration of the bottom 6 of the tank. This variant requires the use of a seal with very flexible lips and offers the possibility of closing and opening the lid 4 on the tank 3 indifferently in the clockwise or counterclockwise direction. Preferably, the tank ramps 10 and lid ramps 11 extend at a substantially identical length L. The length L of the tank ramps 10 and the cover ramps 11 depends on the diameter of the tank 3 and the cover 4. As an indication, on the basis of an embodiment of four tank ramps 10 and four cover ramps 11 and with a tank internal diameter of 245 mm, the length L will be of the order of about 90 mm. Thanks to these characteristics of conformations and dimensions, the collaboration between the tank ramps 10 and the cover ramps 11 is optimal. In the case of a pressure cooker, the tank ramps 10 and the cover ramps 11 will be shaped and dimensioned so as to exert sufficient strength and necessary to meet the standards and specifications that govern this type of device. In particular, and purely for informational purposes, the tank ramps 10 and the lid ramps 11 will be dimensioned so as to be able to produce a tight and resistant connection during the locking that can withstand a test pressure of 500 kPa without separation of the tank 3 and lid 4.
    [0015] In the same way, to avoid radial deformations of the vessel 3, the respective dimensions of the cover 4 and the vessel 3 will be adjusted to limit the play on all their respective circular peripheries. This avoids any radial displacement in order to maintain optimal circularity. Preferably, the tank ramps 10 and the cover ramps 11 have an angular inclination alpha (a) with respect to the extension plane P of the bottom 6 of the tank 3 of the order of 3 degrees for an embodiment as mentioned previously with four ramps and a tank internal diameter of 245 mm. As illustrated in the figures, and particularly preferably, the tank ramps 10 and the cover ramps 11 are evenly distributed and equidistant from each other on the surface of the tank wall 3 and the reentrant portion 13. In this way, it avoids deformations of the vessel 3 and the lid 4. Moreover, to obtain a preferential deformation zone of the lid, and thus to ensure a leak at a certain pressure level, an arrangement of the lengths of the ramps can allow to obtain such a security imbalance. On the other hand to allow the docking of the lid on the tank, in a preferred and unique position, the arrangement of the lengths of the ramps can also achieve it. Advantageously, the apparatus according to the invention comprises at least one pair of tank ramps 10 and a pair of cover ramps 11, and preferably two pairs as shown in the figures.
    [0016] According to the invention, the tank ramps 10 and the lid ramps 11 are obtained by deformation of the constituent material, respectively of the tank wall 7 and the peripheral belt 14. In this way, one obtains vat ramps 10 and cover ramps 11 which form elongate recesses with the concavity oriented towards the inside of the apparatus for the cover ramps 11 and towards the outside of the apparatus for the tank ramps 10. As shown in FIG. 3, the outer surface of the cover 4 is delimited by an outer bearing edge 12 forming a collar and the vessel 3 comprises a peripheral support edge 20 intended to serve as a support for said edge. outside bearing 12 during the introduction of the lid 4. According to a particularly interesting version of the invention and as shown in Figure 3 in particular, the outer bearing edge 12 overhangs the re-entrant portion 13 and ensures l junction with said reentrant portion 13 forming a housing, preferably peripheral, for receiving the sealing means 5 which is intended to come into direct contact with the peripheral bearing edge 20 of the vessel 3. The housing thus realized has a substantially L-shaped cross section extending over the entire periphery of the cover 4 and allows to receive the sealing means 5 whose deformation will ensure sealing of the cooking chamber. As illustrated, the sealing means 5 is for example formed by an elastomeric seal of U-shaped cross-section, one of the lips of which bears directly against the peripheral bearing edge 20. As illustrated, and of preferentially, the upper edge 8 of the tank 3 continues with a substantially vertical zone continuing itself by a slope inclined towards the center of the device forming the peripheral bearing edge 20 against which one of the lips of the sealing means 5 is compressed. As illustrated, the upper edge 8 may be formed by a substantially horizontal circular plate (Figures 5-7) or by a substantially vertical circular plate (Figures 2 to 4) without departing from the scope of the invention.
    [0017] As illustrated and advantageously, the lid 4 comprises in its central part a cavity 22 forming the outer portion of the reentrant portion 13, the central cavity 22 having a domed central zone 23 surrounded by a substantially flat annular zone 24, the convex zone 23 having a regular concavity turned towards the outside of the apparatus. Advantageously, the lid comprises a handling means 25, for example a U-shaped handle connected to the convex central portion 23. The vessel 3 of the pressure cooking appliance according to the invention is also provided with at least one and preferably two handles 30 fixed on the outer face of the wall 7, preferably in diametrically opposite position. The handles 30 allow the transport of the apparatus while facilitating the pouring of the liquid contained in the tank 3. The handles 30 may also be used to serve as a visual means of indexing the relative position of the lid 4 opposite the tank 3 and also serve as a fulcrum to the hand of the user to facilitate the rotation of the lid according to the arrow F avoiding anti rotation tank 3 during locking.
    [0018] The operating mode of the cooking appliance according to the invention is as follows. To achieve the locking of the cover 4 in the tank 3, the user first grasps the cover 4 via the manipulation member 25 and prepares the docking of the cover 4 on the tank 3 (FIG. 5) . For this, the user comes to rest the outer bearing edge 12 against the peripheral bearing edge 20 through the sealing means 5 (Figure 6). The user then rotates the cover 4, for example according to the arrow F in the clockwise direction, until he feels a resistance or a click sound indicating that the collaboration or cooperation between the tank ramps 10 and the cover ramps 11 is optimal. This position corresponds to the tight and resistant connection sought (Figure 7). During the progressive rotation of the cover 4, the latter is progressively led to move downwards towards the bottom 6 thanks to the inclination alpha has tank ramps 11 and cover 10 which gradually compresses the sealing means 5 to ensure the seal between the tank 3 and the lid 4. In this position, the device can then rise in pressure.
    [0019] As illustrated, the pressure cooker is constituted by a pressure cooker, preferably for domestic use. The invention also relates to a method of manufacturing locking means disposed on the vessel and the lid of a pressurized food cooking appliance, said locking means forming tank ramps 10 and lid ramps 11 which are intended to cooperate together by relative rotation of the vessel 3 and the cover 4 so that the cover ramps 11 come under the tank ramps 10 to ensure the locking of the cover 4 on the vessel 3. According to the invention, the vessel ramps 10 and the cover ramps 11 are made in over thickness from the wall 7 of the vessel and / or the cover of the cover by adding material or material deformation. The tank and lid ramps can therefore be made either by assembling the material, or by simple deformation of the constituent material of the tank or lid to achieve the ramps. According to a particularly advantageous version of the invention, the tank ramps and cover ramps are produced by adding, by adding material, the tank ramps inside or outside the tank and / or the cover lines on the outside or on the inside (covering lid) of the cover casing by riveting, welding, gluing or clinching. According to another variant embodiment of the manufacturing method according to the invention, the tank ramps are produced by deformation of the inside or outside of the tank and the cover ramps by deformation of the outside or from the inside of the lid shell by hydroforming or magnetoforming or stamping. The embodiment of a locking mechanism according to the invention implementing an "inverted" bayonet locking mechanism in which the tank ramps 10 are located at a distance from the upper edge 8 of the tank inside the same wall 7 and the cover ramps 11 are arranged on the reentrant portion 13 of the lid 4 so as to be able to lock under the tank ramps 10 inside the vessel itself 3 has many advantages. It has the particular advantage of only using two mechanical elements to ensure the strong bond, to optimize the amount of material used by implementing reduced metal thicknesses without having to use many patches that are necessary in locking devices known in the prior art such as stirrups, locking lugs, jaws or segments for example. The locking mechanism according to the invention also facilitates the ergonomics of closing and opening the device because of the simplicity of the introduction of the lid by the user inside the tank, the user can perfectly visualize the docking of the lid, which can be easily centered since it is placed inside the vessel itself 3 under its upper edge 8, the inner surface of the wall 7 serving as a means of centering.
    [0020] The reduced number of parts needed to ensure the mechanical connection also makes it possible to provide the possibility of equipping the device with many additional accessories.
