    [0001] The present invention relates to a method for drilling a tunnel for receiving a sensor in a beaker and a container for such a method. B.14741 METHOD FOR DRILLING A TUNNEL FOR RECEIVING A SENSOR IN A COOKING CONTAINER a cooking vessel, more particularly a tunnel for receiving a temperature sensor and a cooking vessel resulting from such a method. The cooking vessel is intended to be arranged on a cooking plate, a burner or the like for cooking food including a pan, a saucepan, a saute pan, a Dutch oven or a pressure cooker. Document EP1591049 discloses a cooking vessel comprising a bottom and a temperature sensor arranged in a receiving tunnel formed in the bottom. The method of producing the sensor receiving tunnel disclosed by this document comprises a drilling step. However, standard cookware has bottoms whose thickness varies, for example, from 4 millimeters to 6 millimeters. Thus, a receiving tunnel made by drilling will have to implement a small diameter drill so that there remains a bottom material thickness on both sides of the drilled hole. This thickness of material may not exceed a few tenths of a millimeter. In addition, in order to follow in particular a temperature in a relevant and effective manner, it is necessary to arrange the sensor in the bottom of the cooking vessel sufficiently offset from the edge of the cap, for example, by positioning a sensitive portion of the sensor at a distance of at least 50 millimeters from the edge. Thus, such a method for the realization of a tunnel receiving a sensor 30 by drilling implements a drill of small diameter and great length which will be very fragile and will wear prematurely. In addition, the thickness of the bottom which is very close to the diameter of the drill does not allow any deviation of the drill during drilling, which requires working at low production rates. Finally, the receiving tunnel is made in a bottom which is particularly aluminum. Drilling with a drill of small diameter and length, leads to a high concentration of heat at the tip of the drill, and a great difficulty in removing chips from the hole that "stick" to the drill, with the consequence long loosening times and frequent hole deformations.
    [0002] The object of the present invention is to overcome the aforementioned drawbacks and to provide a method for drilling a tunnel receiving a sensor in a cooking vessel that is economical to implement.
    [0003] Another aim of the present invention is to propose a method for drilling a tunnel for receiving a sensor in a cooking vessel that makes it possible to obtain a tunnel with controlled and constant dimensions from one container to the other. .
    [0004] These objects are achieved with a method for drilling a tunnel for receiving a sensor, in particular a temperature sensor, in a cooking vessel comprising a cap comprising a bottom having a thickness (e) in which said tunnel receiver is realized, characterized in that said method comprises a pre-drilling step using a drill diameter Dl to achieve a first portion of the receiving tunnel and a deep drilling step using a drill diameter D2 for performing a second portion of the receiving tunnel, D1 being greater than D2. A first portion corresponding to a first hole is therefore made during the pre-drilling step. This first hole will serve as a centering gun and will stabilize the end of the longer drill used in the deep drilling step to achieve the second portion, the radial clearance of the longer end of the drill being limited by the wall of the first hole. Indeed, a drill by construction is never perfectly straight. It always has a wrong round. Thus, good guidance of the longer end of the drill makes it possible to produce the second portion in the form of a second hole in the axis of the first and makes it possible to obtain a rectilinear tunnel, without deviation, with controlled and constant dimensions. from one cooking container to another. Advantageously, the pre-drilling and deep-drilling steps are performed in succession so as to optimize the production rate.
    [0005] Advantageously, the ratio between diameter D1 and diameter D2 is between 1.005 and 1.05, preferably between 1.01 and 1.02. Thus, the long drill used in the deep drilling step has a diameter D2 very slightly less than the short drill implemented in the pre-drilling step. This arrangement makes it possible to achieve an excellent centering of the end of the long drill while minimizing the friction of the long drill of diameter D2 in the hole made by the short drill of diameter D1 smaller.
    [0006] Preferably, the diameter D2 is between 2 and 3 millimeters, preferably 2, 5 millimeters. The minimum thickness of the bottom of a standard baking container is about 4mm. Such a diameter thus makes it possible to produce a reception tunnel compatible with all ranges of cooking containers. Advantageously, the first portion of the receiving tunnel has a depth (P1) and the second portion has a depth (P2), the ratio between P2 and P1 being between 2 and 5, preferably between 3 and 4.5. This arrangement makes it possible to obtain a time for implementing the pre-drilling step substantially less than the time to implement the deep drilling step and thus, the production rate can be optimized.
    [0007] Preferably, the depth (P2 + P1) of the receiving tunnel is between 50 and 70 millimeters, preferably 60 millimeters.
    [0008] Thus, a sensor arranged in the bottom of a reception tunnel having such a depth will be sufficiently offset from the edge of the cap of the cooking vessel to detect a parameter, including a temperature, representative of the state of food contained in the container, regardless of the size of the bottom of the cooking vessel.
    [0009] In an advantageous embodiment, in at least one piercing step, a piercing head rotates a drill and generates an axial advance movement of said drill on which is superimposed an axial oscillation at a given frequency. Preferably, the frequency of the axial oscillation applied to the drill is a low frequency of a few hertz. Such drilling is, for example, described in US2453136. Such piercing allows regular chip splitting. As a result, chip jamming phenomena are eliminated and the resulting decreased risk of tool breakage makes the process more reliable. In addition, the life of the drill is lengthened. Indeed the drill works only part of the time because of the cut which becomes interrupted at an optimum frequency, which allows the tool to cool between each cutting phase.
    [0010] Advantageously, in the pre-drilling and deep-drilling steps, the drills are rotated at a rotation speed V1 of between 8,000 and 12,000 revolutions per minute, preferably 10,000 revolutions per minute. This range of rotational speed of the drill allows optimal removal of the chips, especially in aluminum. Preferably, in the deep drilling step, the drill is rotated at an approach rotation speed V2 when it is introduced into the tunnel made in the pre-drilling step, V2 being less than V1. This arrangement avoids amplifying the false round of the long drill. Thus, the end of the long drill can be inserted into the hole made in the pre-drilling step without the risk of touching the edge of this hole. Advantageously, the ratio of the speed of rotation V1 to the rotation speed V2 is between 10 and 100, preferably 20.
    [0011] Advantageously, the method for drilling a receiving tunnel comprises a milling step before the drilling step. This arrangement makes it possible to prepare a flat drilling surface perpendicular to a longitudinal axis of the drill. Thus, it does not generate lateral force on the drill during the pre-drilling step. As a result, the life of the drill will be improved. Preferably, the bottom material in which the receiving tunnel is made is aluminum.
    [0012] The invention also relates to a cooking vessel comprising a cap comprising a bottom having a thickness (e) and a tunnel for receiving a sensor, in particular a temperature sensor, said receiving tunnel being arranged in the thickness ( e), characterized in that the receiving tunnel is made according to the previously described method. Thus, the sensor receiving tunnel has a succession of a first and second portion. The first portion of larger diameter guides the sensor during its introduction into the receiving tunnel and the second portion of smaller diameter is adjusted to the size of the sensor to allow precise positioning, see a slight tightening of the sensor at the bottom of the receiving tunnel. As a result, the sensor can not move and will measure the bottom temperature repetitively and reliably over time.
    [0013] Preferably, the cooking vessel is a pan, a saucepan, a sauté pan, a Dutch oven or a pressure cooker.
    [0014] The invention will be better understood from the study of the embodiments taken in no way limiting and illustrated in the accompanying figures in which: FIG. 1 illustrates a perspective view of a cap of a cooking vessel comprising a tunnel of receiving a sensor according to a particular embodiment of the invention.
    [0015] FIG. 2 illustrates a partial view of the cap and the receiving tunnel in direction II illustrated in FIG. 1. FIG. 3 is a schematic partial sectional view of the raw cap, without the receiving tunnel, along line III. III illustrated in Figure 1.
    [0016] FIG. 4 illustrates a schematic partial sectional view of the cap illustrated in FIG. 5 illustrates illustrated in FIG. 6 illustrates illustrated in FIG. 7 illustrates illustrated in FIG. 8 illustrates illustrated in FIG. Figure 9 illustrates 3, at the milling step. a schematic sectional view 3, after the milling step. a schematic sectional view 3, in the pre-drilling step. a schematic sectional view 3, after the pre-drilling step. a schematic sectional view 3, in the deep drilling step. a schematic view in partial section of the partial cap of the partial cap of the partial cap of the partial cap of the cap shown in Figure 3, after the deep drilling step. As seen in Figures 1 and 2, a cap 2 of a cooking vessel 1 comprises a bottom 3 and a side wall 4. The cap 2 is made of aluminum, for example, by striking a disk or by an operation foundry. The bottom 3 has a thickness (e) equal to 4 millimeters in which a receiving tunnel 11 of a sensor 20 is arranged. The receiving tunnel 11 forms an opening 12 in the side wall 4 and extends, starting from this opening 12, radially towards the center of the bottom 3. The receiving tunnel 11 comprises from the opening 12 a first portion 13 formed by a cylindrical hole of diameter D1 (FIG. 9), then a second portion 14 formed by a cylindrical hole of diameter D2 (FIG. 9), the diameter D1 being greater than the diameter D2. The first and second portions 13, 14 have the same longitudinal axis. The sensor 20, visible in FIG. 1, is notably a temperature sensor, formed by a CTN or a thermocouple. By CTN, a thermistor with a negative temperature coefficient is included. The temperature sensor 20 is provided with two insulated conductor elements 21, 22 which are arranged in a tubular sheath 23 of stainless steel, closed at one end. The temperature sensor 20 is positioned at the bottom of the tubular sheath 23, close to the closed end. The conductive elements 21, 22 are electrically connected to an electronic circuit (not shown in the figures) to process the quantity measured by the temperature sensor 20 and display the temperature. The tubular sheath 23 has a substantially constant diameter D3 along the length of the tubular sheath. The diameter D3 is very slightly less than the diameter D2 of the second portion 14 so that the tubular sheath 23, once completely inserted into the receiving tunnel 11 is held in position in an adjusted manner, almost without play. The diameter D2 being smaller that the diameter D1, there is a greater clearance of the tubular sheath 23 in the first portion 13. The first portion 13 thus serves as a guide zone of the tubular sheath 23 when introduced into the receiving tunnel 11. The wall 4 comprises a groove 6 extending from the opening 12 of the receiving tunnel 11, up the side wall 4. The groove 6 is intended to receive the conductive elements 21, 22, once the tubular sheath 23 introduced into the receiving tunnel 11. A protective cover 7 is arranged on the groove 6 to form a protective channel of the sensor 20 and conductive elements 21, 22. 302 7 82 9 8 The container The cooking element comprises a handle (not shown in the figures), one end of which is fixed to the lateral wall by fastening means (not shown in the figures). The conductive elements 21, 22 and the protective cover 7 are arranged on the handle. FIGS. 3 to 9 illustrate the different steps of carrying out the method for drilling the receiving tunnel 11 of the sensor 20. A partial section of the blank cap 2 is illustrated in FIG. 3. The first step of the method consists in producing by milling a flat surface 15 in the side wall 4 at the bottom 3. A machining head 30 drives a milling cutter 31 with a flat end in rotation and this machining head 30 is driven in a feed movement according to a radial direction relative to the bottom 3 (Fig.4). Thus, the flat end of the cutter 31 will make the flat surface 15 which is perpendicular to the bottom 3 (Fig. 5). The next step of the process consists of a pre-drilling step of the first portion 13 in the form of a hole of diameter D1, for example, 2.55 millimeters and of depth P1 equal to 13 millimeters in the thickness of the bottom 3. A piercing head 33 rotates a drill bit 34 at a speed V1 of, for for example, 10,000 revolutions per minute and generates an axial advance movement of the drill 34. The piercing head 33 is driven in an advance movement in the same radial direction relative to the bottom 3 as that of the head of the drill. machining 30 (Fig.6). Thus the drill 34 will make the first portion 13 of the receiving tunnel 11 depth P1 25 (Fig.7). In an alternative embodiment, an axial oscillation at a given frequency can be superimposed on the advance movement of the forest 34. The method then comprises a step of deep drilling the second portion 14 in the form of a hole of diameter D2, for example, 2.5 millimeters and 30 of depth P2 equal to 47 millimeters in the thickness of the bottom 3. In the same way as for the pre-drilling, a drilling head 36 rotates a drill 37 long at a speed of, for example, 10,000 revolutions per minute and generates an axial advance movement of the drill 37. The drilling head 36 is driven in advance in the same radial direction with respect to the bottom 3 as that of the machining head 30 and that of the drilling head 33 (Fig.8). Thus the drill 37 will make the second portion 14 of the receiving tunnel 11 (Fig.9). The total depth Pi + P2 of the receiving tunnel 11 is therefore equal to 60 millimeters. In an alternative embodiment, an axial oscillation at a given frequency can be superimposed on the advance movement of the forest 37. In an alternative embodiment, during the deep drilling step, the long drill 37 is rotated at a distance of speed of rotation V2 of 500 revolutions per minute when it is introduced in the first portion 13 made in the pre-drilling step and is driven at the speed V1 of 10,000 rpm just before the drill 37 starts the hole corresponding to the second portion 14 of the receiving tunnel 11.
    [0017] Of course, the invention is not limited to the described and illustrated embodiments which have been given by way of example. Modifications are possible, particularly from the point of view of the constitution of the various elements or by substitution of technical equivalents, without departing from the scope of protection of the invention.
    [0018] Thus, in an alternative embodiment, the cooking vessel comprises an aluminum cap having an outer face of the bottom is provided with a perforated plate made of stainless steel. The receiving tunnel is made in the thickness of the aluminum part of the bottom.
