    PRESSURE COOKER WITH INTERLOCKABLE TANK AND LID HANDLES
    The present invention relates to the general technical field of appliances for cooking food under pressure, and in particular to domestic appliances of the pressure cooker type intended to form a cooking enclosure capable of increasing in pressure in order to ensure cooking under vapor pressure. food contained within it.
    The present invention relates more particularly to an appliance for cooking food under pressure comprising a vessel provided with a vessel handle which forms a local protrusion extending radially from the vessel, a lid independent of the vessel, as well as a bayonet locking system designed to pass from an unlocking configuration to a locking configuration by pivoting of the cover relative to the tank according to a predetermined angular travel from a predetermined position of pre-locking of the cover relative to the tank , to bring the cover into a predetermined locking position relative to the tank, said apparatus also comprising a safety element fixed to the cover to move with the latter relative to the tank according to said predetermined angular stroke, said safety element cooperating in interlocking with the bowl handle when the cover occupies said predetermined locking position.
    Pressure cooking appliances, in particular for domestic use, are well known, they generally include a metal tank on which is intended to be attached in a leaktight manner, by means of a flexible annular sealing gasket , a cover also metallic, so as to constitute a cooking chamber capable of rising in pressure. The cover is intended to be linked to the vessel by means of locking means allowing the pressure cooker to move between a configuration for locking the lid relative to the vessel, in which the cooking enclosure is capable of mounting in pressure, and an unlocking configuration in which the cover can be freely separated from the tank. There are different types of locking means well known in the prior art. One of the most widespread systems is the bayonet locking system, which is based on the implementation of tank and cover ramps intended to come into mutual support after rotation of the cover to thus ensure a mechanical retaining connection preventing the separation of the tank and the cover under the effect of the pressure build-up. The cover ramps are conventionally produced by localized folding inward of the annular falling edge of the cover, while the tank ramps are conventionally obtained by folding and cutting the free upper edge of the tank.
    Known bayonet pressure cookers are usually fitted with a bowl handle and a lid which are angularly offset when the lid is attached to the bowl for locking purposes, then travel through a predetermined relative angular stroke until they come into vertical mutual alignment once the locking position reached. In order to secure the use of the appliance, the bowl and lid handles cooperate mechanically when they are aligned in the lid locking position relative to the bowl to ensure interlocking between them, which prevents the user from spread angularly, to avoid any untimely opening of the device when the latter is under pressure.
    These known devices are generally satisfactory, but nevertheless have various drawbacks, particularly in terms of safety, practicality and ergonomics.
    First of all, the user may experience, with known pressure cookers, difficulties in positioning the lid easily and quickly relative to the pan in the predetermined pre-locking position from which the lid can be locked by rotation of the lid. relatively to the tank. This ergonomic problem is compounded by a potential security risk. Known pressure cookers are in fact designed in such a way that the bowl and lid ramps can be partially in mutual engagement, while the bowl and lid handles are totally misaligned, which prohibits any cooperation of safety means carried by said handles.
    The design of known devices therefore penalizes safety, which cannot be ensured in an optimal manner as soon as there is the possibility of engagement of the vessel and cover ramps, that is to say as soon as the device is susceptible to be able to build up pressure.
    The invention therefore proposes to remedy the various drawbacks set out above and to propose a new appliance for cooking food under pressure which, while being light, simple and inexpensive to manufacture, is particularly easy and intuitive to use. , while presenting an improved level of security.
    Another object of the invention is to propose a new appliance for cooking food under pressure of particularly simple and reliable construction.
    Another object of the invention is to propose a new appliance for cooking food under pressure that is particularly safe.
    Another object of the invention is to propose a new appliance for cooking food under very ergonomic pressure.
    Another object of the invention is to propose a new appliance for cooking food under pressure which can be controlled manually in a particularly simple and reliable manner.
    Another object of the invention is to propose a new appliance for cooking food under pressure which facilitates the correct positioning of the cover on the tank when the cover comes into contact with the tank for locking purposes.
    Another object of the invention is to propose a new appliance for cooking food under pressure which allows the user to identify at a glance whether the appliance is locked or not.
    Another object of the invention is to propose a new appliance for cooking food under pressure which is particularly compact and robust.
    Another object of the invention is to propose a new appliance for cooking food under pressure, the design of which limits the risk of the cover escaping from the grip of the user.
    The objects assigned to the invention are achieved using a pressure food cooking appliance comprising a tank provided with a tank handle which forms a local protrusion extending radially from the tank, a tank-independent cover, as well as a bayonet locking system designed to pass from an unlocking configuration to a configuration for pivotally locking the cover relative to the tank according to a predetermined angular travel from a predetermined position of pre-locking of the cover relative to the tank, to bring the cover into a predetermined locking position relative to the tank, said apparatus also comprising a safety element fixed to the cover to move with the latter relative to the tank according to said angular stroke predetermined, said security element cooperating in interlocking with the handle bowl when the cover occupies said predetermined locking position, said apparatus being characterized in that said safety element and bowl handle are at least partially in radial correspondence not only when the cover occupies said predetermined locking position, but also when it occupies said predetermined pre-locking position.

    As illustrated in the figures, the invention relates to an appliance 1 for cooking food under pressure, intended to ensure the cooking of various foods at a pressure level higher than atmospheric pressure, in the presence of steam, and for example steam d 'water. Said steam is generated by heating, within the device 1 and in the presence of food, a cooking liquid, for example an aqueous liquid. The device 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 devices. The device 1 is preferably designed to build up pressure exclusively under the effect of a heating source (on-board or external), without any external pressure supply. The device 1 according to the invention is advantageously designed to be subjected to an external heating source, such as for example a hob.
    The appliance 1 for cooking food under pressure therefore constitutes a pressure cooker, preferably intended to be placed on an independent heating source (for example a hob) for heating the content. The cooking appliance 1 according to the invention comprises at least one tank 2 forming a cooking container, intended to accommodate the food to be cooked and in this case having substantially a symmetry of revolution along a central vertical axis XX ′, which extends in a direction which is similar to the vertical direction when the device 1 is in normal operation, that is to say rests on a horizontal plane. The tank 2 is conventionally made from a metallic material such as stainless steel or aluminum. The tank 2 comprises a bottom 2A, which is for example a multilayer thermally conductive bottom. The tank 2 also comprises an annular side wall 2B which rises between said bottom 2A and a free upper edge 2C, which in this case is circular in shape, and which defines an access opening inside the tank 2. The configuration of this free upper edge 2C will be described in more detail in the following, in relation to the locking means of the device 1. As illustrated in the figures, the tank 2 is provided with at least one handle. tank 3 which forms a local protrusion extending radially (in this case relative to the central axis X-X ') from tank 2, and more precisely from the external face of the annular side wall 2B, towards the outside of the tank 2, and preferably in the vicinity of the free upper edge 2C. Thus, as illustrated in the figures, the tank handle 3 is fixed to said tank 2 so as to project outwardly from the latter so as to thus form a grip intended to be grabbed manually by the user to handle the tank 2 (by example to lift and move it). In the preferred embodiments illustrated in the figures, the cooking appliance 1 comprises two identical handles 3, 4 attached to the side wall 2B of the tank 2 in a diametrically opposite manner relative to the central axis XX ′, said handles 3, 4 being in this case arranged near the free upper edge 2C of the tank 2. It is however perfectly conceivable that the tank 2 is provided with only one tank handle 3, or more than two handles tank (for example three or four), without departing from the scope of the invention.
    The appliance 1 according to the invention also comprises a cover 5 intended to be associated with the tank 2 and locked relative to the latter to form a cooking enclosure capable of increasing in pressure, that is to say an enclosure of sufficiently airtight cooking to allow the pressure rise of the apparatus 1. In order to obtain this hermetic, sealed character, the apparatus 1 advantageously includes a seal 6, preferably formed by a flexible annular seal, made of elastomer by example, intended to be interposed between the cover 5 and the tank 2, thereby preventing any uncontrolled leakage of vapor and / or air between the interior of the enclosure and the exterior. The cover 5 is conventionally made from a metallic material such as stainless steel or aluminum. It advantageously has a shape combined with that of the tank 2, for example a generally discoid shape, which advantageously extends in a mean plane substantially parallel to the mean plane of extension of the bottom 2A of the tank 2 (that is to say - say a substantially horizontal plane in this case) when it is attached and locked on the latter. As illustrated in the figures, the cover 5 is independent of the tank 2, that is to say that it is not permanently attached to said tank 2 from which it is completely separate, and that it can thus be freely associated or separated from the tank 2 by the user (in the absence of locking of course). In the embodiments illustrated in the figures, the cover 5 includes a discoid cover element 5A of shape and dimensions combined with those of the access opening delimited by the free upper edge 2C of the annular side wall 2B of the tank 2 .
    In these embodiments, the cover 5 also advantageously includes an annular belt 5B, for example of substantially cylindrical or frustoconical shape, which rises between a circular upper edge secured to the discoid cover element 5A (in this case at level of the periphery of the latter) and a free circular lower edge, which is for example itself extended by a terminal flange. As illustrated in the figures, the discoid cover element 5A generally extends along a horizontal mean plane, that is to say in this case parallel to the mean plane of extension of the bottom 2A of the tank 2 when the cover 5 is associated with the tank 2 to form the cooking enclosure, while the annular belt 5B extends substantially vertically, that is to say parallel to the central axis XX ′, the end flange s ′ extending meanwhile substantially horizontally. This of course does not exclude in any way that the discoid cover element 5A can be, as illustrated in the figures, slightly curved or locally curved, in order for example to accommodate a control mechanism or for reasons of mechanical strength. In the embodiments illustrated in the figures, the annular belt 5B is formed by a falling edge which extends downwards from the periphery of the discoid covering element 5A. In these embodiments, the cover 5 is intended to come to cover in a substantially adjusted manner the top of the tank 2, so that the annular belt 5B surrounds from the outside ie the top of the annular side wall 2B and the free upper edge 2C, while the discoid cover element 5A rests on the free edge 2C, by means of the seal 6 interposed between the tank 2 and the cover 5. It is however perfectly conceivable that the annular belt 5B is alternatively intended to be inserted within the tank 2, so as to be surrounded by, and contained in, the tank 2, without departing from the scope of the invention.
    The tank 2 and the cover 5 thus constitute respective complementary envelopes, preferably metallic, which, when combined, form a resulting metallic envelope delimiting a closed volume within which the food is intended to cook under vapor pressure. In order to control the cooking pressure, the appliance 1 advantageously comprises a pressure regulating means 8, such as for example a regulating valve.
    Said pressure regulating valve is preferably mounted on the cover 5, so as for example to be carried directly by said cover 5 and arranged to maintain the pressure prevailing in the cooking chamber at a predetermined value substantially constant, called pressure of operation, which exceeds the atmospheric pressure by a value which is for example between substantially 10 and 120 kPa, or for example between 50 and 55 kPa, or between 85 and 90 kpa, or which is for example of the order of 65 kPa, or around 100 kPa. The general operating principle of such a pressure regulating means is well known as such, so there is no need to describe it further here. The appliance 1 for cooking food under pressure advantageously comprises other operating members (for example an opening safety means 21 which will be described in more detail in the following, a pressure relief safety valve, etc.).
    The appliance 1 according to the invention also comprises a bayonet locking system, in order to allow the cooking enclosure formed by the combination of the cover 5 and the tank 2 to reach at least the abovementioned operating pressure without risk of seeing the cover 5 escape under the effect of the pressure prevailing within the enclosure. In other words, the locking system is designed to ensure a mechanical connection between the tank 2 and the cover 5 which is robust enough to prevent the cover 5 from separating from the tank 2 under the effect of the pressure build-up. within the cooking chamber. In this case, the bayonet locking system is designed to pass from an unlocking configuration (illustrated in FIGS. 1, 6, 8, 14 and 15) to a locking configuration (illustrated in FIGS. 8 to 10, 17 and 18) by pivoting of the cover 5 relative to the tank 2, around in this case said central vertical axis XX ′, so as to pass the apparatus 1 from a locking waiting configuration, in which the cover 5 is attached to the tank 2 and rests freely on the latter (Figures 1 and 14) in a locking configuration in which the tank 2 and the cover 5 interact to prevent their free separation (Figure 9 and 17), and vice versa. More specifically, the bayonet locking system of the device 1 according to the invention is designed to pass from its unlocking configuration to its locking configuration by pivoting the cover 5 relative to the tank 2 according to a predetermined angular travel from from a predetermined position for pre-locking the cover 5 relative to the tank 2 (illustrated in FIGS. 1 and 14), to bring the cover 5 to a predetermined locking position relative to the tank 2 (illustrated in FIGS. 9 and 17).
    Thus, in the embodiments illustrated in the figures, the device 1 changes from its locking standby configuration (corresponding to the pre-locking position of the cover 5) to its locking configuration (corresponding to the locking position of the cover 5) by rotation of the cover 5 relative to the tank 2 along said predetermined angular travel a around the central axis XX ′, in a clockwise direction S1, and changes from its locking configuration to its waiting configuration for locking by rotation of the cover 5 relative to the tank 2 along said predetermined angular travel a around the central axis XX 'in an opposite counterclockwise direction S2, it being understood that the reverse is entirely possible without leaving the scope of the invention (counterclockwise direction S1 and clockwise direction S2). The bayonet locking system of the cooking appliance 1 advantageously comprises for this purpose first and second series of protuberances 9A-9H, 10A-10H which are secured respectively to the cover 5 and to the tank 2 and which are designed, in order to ensure the locking and unlocking of the cover 5 relative to the tank 2, in order to engage, respectively disengage, mutually by rotation of the cover 5 relatively the tank 2 around the central vertical axis XX 'along said stroke predetermined angle a. As is well known as such, the protrusions 9A-9H, 10A-10H of each of said first and second series are intended to cooperate in pairs, that is to say that each protuberance of one of said series is caused, by rotation of the cover 5 relative to the tank 2, to pass under a corresponding protuberance of the other series to lock the cover 5 relatively to the tank 2. In the embodiments illustrated in the figures, the protrusions 9A-9H of the first series, integral with the cover 5, protrude radially inward of the lid 5, while the protrusions 10A-10H of the second series, integral with the tank 2, protrude radially from the external face of the wall side 2B of the tank 2, towards the outside of the latter. It is however perfectly conceivable that the locking protuberances 9A-9H of the cover protrude towards the outside of the cover 5 and that the protuberances 10A-10H of the tank then protrude radially towards the inside of the latter. The invention is therefore not limited to a particular configuration of the locking ramps of the bayonet system, the main thing being that the protrusions of the cover 9A-9H and of the tank 10A-10H, respectively forming cover and tank ramps , cooperate together by relative rotation of the tank 2 and the cover 5, in this case along the central vertical axis XX ′, so that the cover ramps are positioned under the tank ramps in order to achieve a mechanical connection between the tank 2 and the cover 5 capable of withstanding the internal pressure prevailing in the cooking chamber. In the examples illustrated in the figures, each protuberance 9A-9H of the cover is constituted by an element in volume obtained by a local volume deformation of the material constituting the envelope of the cover 3, and more precisely of the annular belt 5B along which are preferably arranged, at regular intervals or not, the protrusions 9A-9H. Each protuberance 9A - 9H thus forms a protuberance, which comes in one piece with the annular belt 5B and which projects from said annular belt by defining on one side an internal convex face and on the other side, in "negative", an opposite concave outer face corresponding for example to the application imprint of a forming tool, preferably a stamping tool. The invention is however absolutely not limited to the implementation of specific outgrowths 9A-9H, and in particular obtained by stamping as in the examples illustrated in the figures. It is for example entirely conceivable that the protuberances 9A-9H of the cover are formed by flat tongues obtained by localized folding inward of the free edge of the annular belt 5B. The use of an element in volume is preferred, however, because it makes it possible to easily obtain, by simple deformation of material (drawing or other), a protuberance which has excellent mechanical properties and reduced dimensions. Thanks to these reduced dimensions, it is possible to switch the device 1 from the locking standby configuration (pre-locking position of the lid 5 relative to the tank 2) to the locking configuration (lid locking position 5 relative to the tank 2) by relative rotation of the cover 5 and the tank 2 according to a predetermined angular travel a relatively small, preferably less than 30 °, for example between 10 ° and 25 °, it being understood that the invention n is not limited to a particular angular travel value a, which can be greater than or equal to 30 °, or on the contrary significantly less than 30 °.
    Thus, in the examples illustrated in the figures, the use of elements in stamped volume allows, thanks to the reduced size of the latter, to implement eight ramps corresponding to a predetermined angular travel of 22 ° 30 ’. Such an angular travel value, clearly lower than the values conventionally observed in the prior art, is likely to improve the ergonomics of handling the device 1 and also allows, as will emerge in more detail from the description which follows, to contribute advantageously to the safety of use of the device 1. The use of such a stamped volume element to form, by local deformation of the cover envelope 5, the cover ramps, also allows, for capacity devices more important, to use for example ten ramps (in which case the angular travel a is for example equal to 18 °, or even twelve ramps, in which case the angular travel a is for example equal to 15 °).
    In the examples illustrated in the figures, the protuberances 10A-10H of the tank are formed by an annular rim which projects outwards from the free upper edge 2C, notches 11 A-11H being formed through said annular rim. allow the passage of said cover protrusions 9A-9H, so that the portions of said annular rim which extend between each notch 11A-11H form the respective vessel ramps intended to cooperate with the cover protuberances 9A-9H which form the ramps cover. Thus, when the cover 5 comes to cover the tank 2, the protuberances 9A-9H of the cover can pass through the notches 11A-11H to find themselves lower than the annular rim. The device 1 is then in its pre-locking configuration (also called locking waiting configuration), from which the locking configuration can be achieved by simply rotating the cover 5 relative to the tank 2 according to the angular travel a predetermined around the vertical axis X-X ', which has the effect of angularly shifting the protrusions 9A-9H of the cover 5 and the notches 11A-11H of the annular rim, achieving a locking of the "bayonet" type . Advantageously, as illustrated in the figures, each tank ramp extends along an angular sector β which is much greater than the angular sector Ω of extension of each of the cover ramps.
    The use of cover ramps in the form of volume elements obtained by localized deformation of the cover envelope 5 makes it possible to implement wider tank ramps, and therefore stronger than traditional tank ramps , so that it is for example entirely possible to implement a cover with ten cover ramps arranged at regular intervals and in this case to resort to an angular stroke reduced to 15 ° (and not 18 °). In this case, in the locking configuration, the centers of the cover ramps are not aligned with the corresponding centers of the tank ramps, i.e. the cover ramps are not positioned centrally relative to the tank ramps. In the embodiment of FIGS. 1 to 13, the vessel and cover ramps are eight in number respectively, but the predetermined angular travel is less than 22 ° 30 ', so that in the locking configuration, and as this is visible in Figure 11, the cover ramps do not come to bear centered against the tank ramps but are instead positioned offset under and against the tank ramps.
    According to the invention, the device 1 also comprises a safety element 12 fixed to the cover 5 to move with the latter relative to the tank 2 according to said predetermined angular travel. In other words, the security element 12 is embedded on the cover 5 so as to form with the latter a unitary sub-assembly. The security element 12 is fixed to the cover 5 by means enabling the security element 12 to be immobilized in position relative to the cover 5. Thus, when the cover 5 is pivoted relative to the tank 2 along the stroke angular a to pass ia predetermined pre-locking position to the predetermined locking position, the security element 12, because it is carried by the cover 5, also undergoes pivoting according to the same angular travel a. In the examples illustrated in the figures, the security element 12 is disposed on the discoid cover element 5A, at the periphery of the latter. The security element 12 cooperates in interlocking with the bowl handle 3 when the cover 5 occupies said predetermined locking position.
    In other words, the security element 12 and the bowl handle 3 are designed to cooperate mechanically, when the cover is in the predetermined locking position, to attach to each other and thus limit their ability relative displacement. Preferably, said interlocking of the security element 12 with the tank handle 3 is an angular interlock in the horizontal plane perpendicular to the central axis XX ′, in order to prevent the cover 5 from pivoting relative to the tank 2 to return, from its predetermined locking position, to its pre-locking position.
    According to the invention, said safety elements 12 and tank handles 3 are at least partially in radial correspondence (in this case relative to the central axis XX ′) not only when the cover 5 occupies said predetermined position of locking, but also when it occupies said predetermined pre-locking position. In other words, a first portion (at least) of said safety element 12 and a first portion (at least) of said tank handle 3 are inscribed in the same first radial plane P1 when the cover 5 occupies said predetermined position pre-locking. Said first radial plane P1 includes the central axis XX ′ and is perpendicular to the horizontal plane. Thus, as soon as the cover 5 occupies its predetermined pre-locking position, and even before it is found in its locking position, the security element 12 is at least partially opposite the handle. tank 3, which allows not only the user to easily identify the pre-locking position, but also to be able to implement, if desired, mechanical cooperation between the tank handle 3 and the element of safety device 12 aiming, for example, at preventing the pressure build-up of the device 1. Likewise, said first portion of said safety element 12 and a second portion of said tank handle 3 are advantageously inscribed in the same second radial plane P2 when the cover 5 occupies said predetermined locking position, said first and second radial planes P1, P2 being intersecting, while also being both perpendicular to the plane horizontal and both passing through the central axis XX '.
    Thus, preferably, the security element 12 is always at least partially in radial alignment with the bowl handle 3 throughout the predetermined angular travel of the cover 5 between its pre-locking and locking positions. The use of an angular stroke of reduced amplitude, for example less than 30 ° as explained above, proves to be particularly advantageous by making it possible to minimize the amplitude of the angular sector along which extends the bowl handle 3, that is to say to minimize the width L of said tank handle 3. In the particularly advantageous embodiments illustrated in the figures, the use of cover ramps in the form of local volume elements proves to be particularly advantageous since the value of the predetermined angular travel conditions the width L of the bowl handle 3 so as to make the safety element 12 and the bowl handle 3 coincide radially, as soon as the cover is in predetermined pre-locking position.
    In the embodiments illustrated in the figures, the security element 12 is designed to adopt a configuration in which it protrudes radially at least in part from the cover 2, so as to at least partially overhang the bowl handle 3 when the cover 5 occupies the predetermined pre-locking position. This means that in this embodiment, which corresponds to the examples illustrated in the figures, at least part of the safety element 12 is aligned vertically with at least part of the bowl handle 3 when the cover 5 occupies its predetermined position. pre-locking. This vertical alignment can be such that, as illustrated in the figures, the concerned portion of the safety element 12 is located above the concerned portion of the tank handle 3, it being understood that it is entirely possible to implementing a reverse configuration where the concerned portion of the safety element 12 is located below the concerned portion of the tank handle 3. Preferably, and as illustrated in the figures, the safety element 12 overhangs the at least partially the bowl handle 3 not only when the cover 5 occupies said predetermined locking position, in order to allow interlocking cooperation of the bowl handle 3 with the security element 12, but also when it occupies said position predetermined pre-lock.
    Preferably, said interlocking cooperation of the security element 12 with said tank handle 3 is a male / female cooperation, said security elements 12 and tank handle 3 having respectively a female conformation and a complementary male conformation, or conversely (that is to say that the security element 12 has the male conformation while the tank handle 3 has the female conformation). Thus, in this preferred embodiment, at least part of the safety element 12 is designed to fit together with a corresponding part of the bowl handle 3 (or at least with a complementary element carried by said bowl handle 3) to ensure the interlocking of the tank handle 3 with the safety element 12, in order to prevent any pivoting of the cover 5 relative to the tank 2 in the horizontal plane capable of bringing the cover 5 out of its predetermined locking position. In the preferred embodiments illustrated in the figures, the security element 12 comprises a main body 13 fixedly attached to the cover 5, that is to say that the main body 13 is directly connected to the cover 5 so as to be immobilized relative to the latter, for example by means of an embedding type connection. In the first embodiment illustrated in Figures 1 to 13, the main body 13 is in the form of an end portion of a cross member 14 of plastic material which locally covers the discoid cover element 5A according to a diameter of this latest. The crosspiece 14 in question thus extends longitudinally between two diametrically opposite ends which are substantially flush with the edge of the cover 5, preferably without protruding radially from the latter (cf. FIG. 5). In the second embodiment of FIGS. 14 to 18, the main body 13 is this time formed not by a crosspiece which extends over a whole diameter of the cover 5 without protruding radially from the latter, but in this case by a block disposed at the periphery of the cover 5, on the discoid cover element 5A, and which projects radially outwards from the cover 5 as can be seen in particular in FIG. 16. The block forming the main body 13 of the apparatus of Figures 14 to 18 is made, like the crosspiece 14, preferably of plastic, and is fixedly attached to the discoid cover element 5A.
    Advantageously, the apparatus 1 also comprises a gripping member 15 which is fixedly attached to the cover 5 and is designed to be gripped manually to allow the handling and transport of the cover 5 through it, and in particular the pivoting of the cover 5 relative to the tank 2 according to said predetermined angular travel. Preferably, and in accordance with the first embodiment of Figures 1 to 13, the main body 13 comes integrally with said gripping member 15. More specifically, in the embodiment illustrated in Figures 1 to 13, the cross member 14 has a curved conformation at its center intended to form the gripping member 15, which therefore forms, with the main body 13 (which corresponds to one of the ends of the cross-member 14), one and the same piece in one piece. It is however perfectly conceivable, without departing from the scope of the invention, for the gripping member 15 to be completely separate from the main body 13, in accordance for example with the embodiment of FIGS. 14 to 18. In this embodiment, the gripping member 15 is formed by a central knob which rises substantially from the center of the discoid covering element 5A and which is completely separate and independent from the main body 13.
    As illustrated in FIGS. 1 to 18, the security element 12 advantageously comprises, in addition to the main body 13, a lock 16 mounted movably relative to said main body 13 between:
    a first position in which the latch 16 can engage, when the cover 5 occupies said predetermined locking position, a complementary conformation 17 of locking carried by the tank handle 3,
    - And a second position in which the latch 16 is sufficiently spaced from said complementary locking configuration 17 to disengage from the latter when the cover 5 occupies said predetermined locking position.
    In the embodiments illustrated in the figures, when it occupies its first position, the latch 16 at least partially overhangs the tank handle 3 when the cover 5 occupies said predetermined pre-locking position.
    Advantageously, and as illustrated in the figures, said first position of the latch 16 is a deployed position in which at least a portion of said latch 16 projects radially from said cover 5 to engage said complementary conformation 17 of locking, while said second position is a retracted position wherein said portion of the latch 16 is retracted towards the inside of the cover 5 to disengage from said complementary locking configuration 17.
    Advantageously, the latch 16 is mounted to slide, and even more preferably to radial sliding, relative to the main body 13, in accordance with the embodiments illustrated in the figures, it being understood that the invention is not however limited to an assembly sliding and that other types of mechanical connection (pivoting for example) can be implemented between the main body 13 and the latch 16.
    In the first embodiment illustrated in FIGS. 1 to 13, the latch 16 is in the form of a tongue which, in the deployed position, projects radially over a distance D1 from the cover 5 (cf. FIG. 4) while in the retracted position, said tongue either does not substantially project radially outward from the cover 5, or projects radially outward from the cover 5 over a distance D2 which is less than the distance D1.
    In the second embodiment of FIGS. 14 to 18, the latch 16 is advantageously in the form of a plate-shaped cursor mounted against and under the main body 13 between a retracted position in which the cursor in question does not overflow radially outward from the main body 13, and a deployed position in which it, on the contrary, projects radially outward from said main body 13.
    In the first embodiment of Figures 1 to 13, the latch 16, in its first position (which is advantageously a deployed position) preferably extends longitudinally between an inner end 16A in contact with the main body 13 and a free outer end 16B, said complementary conformation 17 advantageously forming a housing, that is to say a cavity, intended to receive therein said free external end 16B when said latch 16 and cover 5 respectively occupy said first position (deployed position ) and predetermined locking position. Thus, in the locking configuration of the device 1, a free end portion of the lock 16 is captured in the housing integral with the tank handle 3 to prevent any untimely return of the cover 5 to its predetermined unlocking position from its predetermined locking position.
    In the second embodiment of FIGS. 14 to 18, the complementary conformation 17 this time forms not a housing but a locking protuberance which protrudes from the surface of the bowl handle 3. In this case, the bowl handle 3 for example has a substantially planar upper surface provided with a lug which rises vertically from said planar surface to form said blocking protuberance. In this embodiment, the latch 16 for its part forms a housing 18 intended to receive the locking protuberance when said latch 16 and cover 5 occupy respectively said first position (position which is in this case a retracted position) and predetermined position lock.
    Thus, once the cover 5 in the predetermined locking position with the bolt 16 in its first position where it engages the complementary conformation 17, it is impossible for the user, due to the mechanical cooperation between bolt 16 / complementary conformation 17, to rotate the cover 5 so that it leaves its predetermined locking position and returns to its predetermined pre-locking position. This avoids any untimely unlocking attempt which could endanger the user.
    There are of course a multitude of possibilities for controlling the position of the latch 16, whether it is a purely manual, semi-automatic or fully automatic control.
    For example, the security element 12 comprises an elastic return means 19 interposed between said main body 13 and latch 16 to permanently recall the latch 16 in its first position, which is preferably the deployed position mentioned above, or to recall permanently said lock in its second position (which is preferably the retracted position mentioned above). Preferably, said elastic return means 19 comprises a helical spring, it being understood that the invention is not limited to a particular elastic return means and that any suitable elastic body may be suitable depending on the design chosen. In this preferred embodiment, the latch 16 tends to occupy its permanently deployed position under the effect of the elastic return to which it is subjected, and returns to its retracted position for example under the effect of the exercise by the user d '' a direct control force opposite to the elastic restoring force. For example, the security element 12 comprises a control member 20 manually movable relative to the main body 13 for manually controlling the movement of the latch 16 from its first to its second position and / or from its second to its first position. The control member 20 is for example directly integral with the lock 16, and advantageously carries the latter as in the embodiment illustrated in Figures 1 to 13 according to which the control member 20 and the lock 16 are formed by a single and same piece in one piece.
    In this case, the control member 20 can be used by the user to push the latch 16 back into its retracted position, against the elastic return force exerted by the elastic return means 19. The operation of this variant of the device 1 can for example be the following:
    - The lock 16 is naturally in the deployed position under the effect of the return force exerted by the spring forming the return means 19.
    - The cover 5 is placed in its predetermined pre-locking position, with the lock 16 in the deployed position which partially overhangs the tank handle 3.
    - Then the user pivots, by means of the gripping member 15, the cover 5 from its predetermined pre-locking position to its predetermined locking position while exercising, when the cover 5 arrives in the vicinity of its pre-locking, a control force on the control member 20 to manually control the movement of the lock in its second position (retracted position) in order to bring the cover 5 into its locking position without the lock 16 blocking the movement coming to abut against the side wall of the housing carried by the tank handle 3.
    - Then once the cover 5 has reached the locking position, the user can release his effort on the control member 20 which will cause the elastic return of the lock 16 in its deployed position, so that the free end portion of the lock 16 will be captured in the housing forming a complementary conformation 17 for locking carried by the tank handle 3.
    - Subsequently, to unlock the cover if the security conditions (pressure level) allow it, the user will first of all exert a force on the control member 20 to return the latch 16 to its retracted position at 'against the elastic restoring force exerted by the means 19, then offset angularly, thanks to the gripping member 15, the cover 5 out of its predetermined locking position.
    The invention is however not limited to this particular embodiment. It is for example entirely conceivable, without departing from the scope of the invention, that the safety element 12 does not include an elastic return means 19, in which case the control member 20 can be used to move the latch 16 from its first to its second position and from its second to its first position (whereas in the embodiment of FIGS. 1 to 13, the control member 20 does not directly move the latch 16 from its second to its first position, this movement being more directly ensured by the elastic return means 19). It is also perfectly conceivable, without departing from the scope of the invention, that the latch 16 is not directly carried by the control member 20, as in the example of FIGS. 1 to 13, but the control member 20 can be moved manually not only relative to the main body 13, but also relative to the latch 16, which in this case can advantageously be subjected directly to the elastic return force exerted by the elastic return means 19. In this latter particular embodiment, the security element 12 can include a blocking member which blocks the latch 16 in its second position, against the restoring force exerted by the elastic return means 19. In this case, the control member 20 is used to move the locking means in question so that it disappears and thus allows the lock 16 to regain automatically, under the effect of the elastic return force, its first In the first position, it is also conceivable that the elastic return means recalls the lock 16 not in its first position but rather in its second position, all of the alternative variants envisaged above remaining applicable mutatis mutandis.
    In the embodiment of Figures 14 to 18, the control member 20 allows for example not only to manually control the movement of the latch 16 from its first position (retracted position) to its second position (deployed position) but it advantageously allows also to control the movement of the latch 16 from its second position (deployed position) to its first position (retracted position). It is also quite possible in this embodiment to implement an elastic return means interposed between the main body 13 and latch 16 to permanently recall the latch 16 either in its first position or in its second position. All the variants envisaged previously in relation to the first embodiment of FIGS. 1 to 13 are again entirely applicable to this second embodiment of FIGS. 14 to 18.
    It is also conceivable that the passage of the cover 5 from its predetermined pre-locking position to its predetermined locking position automatically and temporarily locks the lock 16 in its second position and / or in its first position. For example, in the first embodiment of Figures 1 to 13, the cover handle 3 may advantageously be provided with a cam surface which cooperates with a complementary cam surface of the lock 16 so that the latter is pushed back into its second position under the effect of the rotation of the cover 5 from its predetermined pre-locking position to its predetermined locking position, the latch 16 returning automatically, under the effect of the elastic return means 19, in its first position a once the cam surface of the bowl handle 3 has passed, so as to be caught in the housing forming a complementary conformation 17.
    The reverse is however not possible and the user must exert a positive force on the control member 20 to unlock the cover 5. In the embodiment of FIGS. 14 to 18, the latch 16 is for example permanently pushed back in its deployed position (which corresponds to the second position of the latch 16), under the effect of the elastic return to which it is permanently subjected. The tank handle 3 is advantageously provided with a cam surface designed to cooperate with a complementary cam surface carried by the lock 16 to push the latter back, under the effect of the pivoting of the cover 5 from its predetermined pre-locking position. in its pre-terminated locking position, in its retracted position where the housing 18 carried by the bolt 16 can come to capture the protuberance forming a complementary conformation 17 carried by the tank handle 3. It is also possible, in this embodiment of FIGS. 14 at 18, that the latch 16 is permanently subjected to an elastic restoring force which tends to keep it in its first position (retracted position). In this case, the security element 12 may advantageously comprise a blocking member movable between a blocking position in which the blocking means maintains the latch 16 in its second position against the elastic restoring force, and a release position in which the locking means is erased to let the latch 16 return to its first position under the effect of the elastic restoring force. The control member 20 advantageously controls in this case the passage of the locking member from its locking position to its release position. It is also possible that the passage of the blocking means from its blocking position to its release position is automatically controlled by the cooperation of cam surfaces carried respectively by the bowl handle 3 and the safety element 12, in which case the 'control member 20 can this time be used to reset the mechanism, that is to push the latch 16 in its deployed position (second position), if of course the security conditions (pressure level) allow.
    The control member 20 can be in any suitable form, and can preferably be slidably mounted relative to the main body 13, either in a radial direction (embodiment of Figures 1 to 13) or in a tangential direction (embodiment of Figures 14 to 18). The control member 20 is for example in the form of a pusher, a lever, a zipper, a slider, a button ... or any other suitable design.
    Preferably, in order to provide optimum safety in use, the device 1 comprises an opening safety means 21 capable of changing, under the effect of the pressure level prevailing in the device 1 (this is ie in the cooking chamber), between a release configuration, in which it authorizes the unlocking of the cover 5 relative to the tank 2, and a blocking configuration, in which it prohibits the unlocking of the cover 5 relative to the tank 2. To this end, the safety means 21 comprises an element 21A movable between a safety position in which it blocks the latch 16 in its first position and a neutral position in which it does not interfere with the latch 16 for authorize the latter to reach its second position from its first position. Preferably, the neutral position is a flight position in which the security means 21 communicates the interior of the enclosure with the outside, while the blocking position is a sealed position in which the security means 21 does not put the interior of the cooking chamber in communication with the outside, which allows the pressure in the chamber to rise. For example, the element 21A is mounted to slide vertically between a high position (corresponding to the safety position) in which it is pushed back as soon as the pressure within the device 1 reaches a predetermined level, and a low position (corresponding to the neutral position) in which it is maintained under the effect of its own weight, as long as the pressure within the device 1 does not reach said predetermined level. Preferably, in its high position, the element 21 A, which is for example in the form of a safety finger, is capable of cooperating, directly or indirectly, with the lock 16 to prevent the latter from leaving its first position in which it engages the complementary conformation 17. For example, in the embodiment of FIGS. 1 to 13, the finger 21A, when it is in the high position, is housed in a complementary conformation of the control member 20 which carries the latch 16 (cf. FIG. 12), thus preventing the movement of the control member 20 and therefore of the latch 16. It is however entirely possible, without going beyond the framework of the invention, that the safety finger 21A cooperates directly with the latch 16.
    A light is also advantageously provided in the body of the control member 20, so that the top of the safety finger 21A is visible when it is in the high position, thus making it possible to visually indicate to the user the state of operation of the device 1. The safety means 21 thus forms a safety means on opening, which prevents any inadvertent opening when the device 1 is under pressure.
    Advantageously, when the lock 16 is in its second position, it cooperates with the safety means 21 to prevent the latter from reaching its blocking configuration from its release configuration. This safety feature at poor closing, which prevents the device 1 from rising in pressure until the latch 16 is not properly in its first position, can for example be implemented by means of an orifice made through the control member 20 and whose dimensions are substantially adjusted to that of the finger 21A, so that when the orifice is not exactly at the right of the finger 21 A, the latter abuts against the edges of the hole in question which prevents it from reaching its blocking position.
    Thanks to the characteristic of the invention according to which the safety element 12 and the tank handle 3 are in radial correspondence (at least partially) when the cover 5 occupies its predetermined pre-locking position, it is possible to set works an early mechanical collaboration between the lock 16 and the tank handle 3, in the pre-locking position of the cover 5 relative to the tank 2, in order for example to guarantee that the lock is maintained in this pre-locking position 16 in a position preventing the safety means 21 from reaching its blocking position. To this end, it is for example possible to implement a cooperation of cam surfaces carried respectively by the tank handle 3 and the latch 16 in order to maintain said latch 16 in an intermediate position between its first and second positions, intermediate position which prohibits the rise of finger 21A into the upper position corresponding to the blocking configuration. Other cooperation is of course conceivable, for example mechanical cooperation between the tank handle 3 and the main body 13 to interact directly or indirectly with the safety means 21.
