    [0001] The present invention relates to the technical field of methods and apparatus for cooking and / or heating foods using steam. The present invention relates more particularly to methods and apparatus in which the contact of food with steam is limited or avoided. It is known from EP 1 651 084 an apparatus for cooking and / or heating food, comprising a steam generating device and a lid mounted movably relative to a receptacle. However, the steam from the steam generating device is injected into the cooking chamber formed by the lid and the receptacle throughout the cooking. An object of the present invention is to provide a method for cooking and / or heating food using steam, which promotes the preservation of vitamins and minerals, as well as preserving the taste of food. Another object of the present invention is to provide a method for cooking and / or heating food using steam, which simplifies the heating and / or cooking food.
    [0002] Another object of the present invention is to provide a method for cooking and / or heating food using steam, which allows cooking and / or heating food quickly. Another object of the present invention is to provide a method for cooking and / or heating foods using steam, which makes it possible to prepare sauces and / or dishes in sauce. Another object of the present invention is to provide a method for cooking and / or heating food using steam, wherein crushing of food is limited or avoided. Another object of the present invention is to provide an apparatus for cooking and / or heating food using steam, which promotes the conservation of vitamins and minerals, as well as the preservation of taste of food. Another object of the present invention is to provide an apparatus for cooking and / or heating foods using steam which is simple to use. Another object of the present invention is to provide an apparatus for cooking and / or heating food using steam, which allows to cook and / or heat food quickly. Another object of the present invention is to provide an apparatus for cooking and / or heating food using steam, which makes it possible to prepare sauces and / or dishes in sauce. Another object of the present invention is to provide an apparatus for cooking and / or heating food using steam, in which the production of several successive dishes is facilitated. Another object of the present invention is to provide an apparatus for cooking and / or heating food using steam, wherein crushing of food is limited or avoided.
    [0003] These objects are achieved with a method for cooking and / or heating food consisting of supplying steam to a vapor expansion chamber comprising a deformable and / or mobile confinement wall partially delimiting an enclosure receiving food to be heated and / or cook. Thus food can be cooked in a confined manner by limiting or eliminating the leaching of food by the steam. Such a method promotes the conservation of vitamins and minerals, as well as preserving the taste of food. This process does not require prior conditioning of food, which can be simply arranged in the enclosure. Sauces and / or dishes in sauce can be prepared using this method. Advantageously, the method consists in supplying the chamber with steam before carrying out at least one heating and / or cooking phase without supplying the chamber with steam. This arrangement makes it possible to obtain a faster temperature rise of the food present in the enclosure, favorable to the conservation of vitamins and minerals, while benefiting from a heating and / or a confined cooking of the food when the food are sufficiently warmed, which prevents the leaching of food by steam. According to one embodiment, the method consists in supplying the chamber with steam for a determined period of time. This arrangement avoids the use of a temperature measurement, such a measure being difficult to achieve in a simple and economical way to obtain a reliable value of the food temperature. The method may especially consist in supplying the chamber with steam for a period of between 1 and 3 minutes. A rapid rise in temperature contributes to better conservation of vitamins and minerals. According to another embodiment, the method consists in using an enclosure comprising at least one inlet opening supplied with steam, for injecting steam into the chamber through the inlet opening or openings, in a first phase, and using the steam supply of the vapor expansion chamber to close the intake opening (s) with the containment wall, in a second phase. Such a method makes it possible to feed the chamber with steam during the first phase and then to stop supplying the chamber with steam for a second phase, without requiring a reduced duration. These arrangements do not require particular control devices. Advantageously, the method consists in using an enclosure comprising at least one discharge opening and supplying the chamber with steam to expel the air present in the enclosure through the outlet or openings. This arrangement expels the air in the chamber when steam is admitted into the chamber, which also helps to accelerate the heating and / or cooking food in the enclosure. The expulsion of air, and therefore oxygen, out of the enclosure also helps to limit the oxidation of sensitive nutrients. Advantageously then, the method consists in using the steam supply of the vapor expansion chamber to close the evacuation opening or openings with the confinement wall. These arrangements do not require specific control devices to close the vent or openings. Advantageously, the process consists in regulating the pressure prevailing in the vapor expansion chamber. This arrangement makes it possible to limit crushing of foods. Advantageously then, the process consists in limiting the pressure in the vapor expansion chamber to a value less than or equal to 10 millibars, and preferably less than or equal to 5 millibars. Such values make it possible in particular to press the containment wall against food by limiting their crushing. These objects are also achieved with an apparatus for cooking and / or heating food, having a device for producing steam and an enclosure for receiving food to be heated and / or cooked, since this apparatus comprises an expansion chamber steam vapor fed by the steam generating device, and in that the vapor expansion chamber comprises a deformable and / or mobile confinement wall partially delimiting the chamber. Thus the containment wall is heated by steam from the steam generating device. This provision allows to consider a confined cooking without using a cooking bag.
    [0004] The deformable wall and / or mobile can come into contact with food to help their heating and / or cooking. According to an advantageous embodiment, the confinement wall is at least partially made of elastically deformable flexible material.
    [0005] This arrangement makes it easier to adjust the volume of the enclosure to the food present in the receptacle. This arrangement also contributes to improving the performance of heat exchanges between steam and food. Alternatively, the containment wall may include at least one rigid portion surrounded by a deformable portion.
    [0006] Advantageously then, the confinement wall has a rest position at least partially concave with respect to the enclosure. This arrangement makes it possible to obtain an enclosure of greater volume while maintaining a compact construction. Advantageously, the enclosure is partially delimited by a removable receptacle. This arrangement makes it easier to set up and remove food. This arrangement also facilitates the cleaning of the device. Advantageously then, the receptacle carries a removable perforated support and has a juice recovery space arranged below a perforated portion of the perforated support. This arrangement makes it possible to collect cooking juices flowing out of the food. Advantageously, the chamber comprises at least one inlet opening communicating with the steam generating device for injecting steam into the chamber. This arrangement makes it possible to obtain a faster rise in the temperature of the food present in the enclosure, by injecting steam into the enclosure at the beginning of the heating and / or cooking of the foodstuffs, to saturate them with steam. Advantageously then, or the inlet openings are arranged in the receptacle. This arrangement makes it possible to obtain a particularly simple construction. Advantageously, the containment wall displaced by the steam present in the vapor expansion chamber may occupy at least one position closing the inlet or openings. This arrangement allows to inject steam into the chamber for a limited period, while maintaining a simple construction of the device. Advantageously, the enclosure has at least one discharge opening communicating with the outside of the device. This arrangement makes it possible in particular to expel the air present in the chamber when steam is admitted into the chamber. The expulsion of air from the enclosure also helps to accelerate the heating and / or cooking of food in the enclosure. The expulsion of air, and therefore oxygen, out of the enclosure also helps to limit the oxidation of sensitive nutrients.
    [0007] Advantageously then, or the discharge openings are formed in a sealing ring belonging to a portion of the movable enclosure relative to the receptacle. This arrangement makes it possible to obtain a particularly simple construction. Advantageously, the containment wall displaced by the steam present in the vapor expansion chamber can occupy at least one position closing the evacuation opening or openings. Thus the containment of the enclosure containing the food can be simply obtained by filling the steam expansion chamber, after the expulsion of air. This arrangement simplifies the construction of the device.
    [0008] Advantageously, the apparatus comprises control means for controlling the steam production of the steam generating device as a function of the vapor pressure prevailing in the vapor expansion chamber. This arrangement makes it possible to limit crushing of foods.
    [0009] Advantageously, the control means are provided for implementing the cooking method according to at least one of the aforementioned characteristics. The invention will be better understood from the study of an exemplary embodiment, taken in a nonlimiting manner, illustrated in Figures 1 to 11, in which: - Figure 1 is a perspective view and partially in section of an embodiment of an apparatus for cooking and / or heating food according to the invention, in which the enclosure for receiving the food to be cooked and / or heated is in the closed configuration, - Figure 2 is a view of perspective of a perforated support used with a receptacle belonging to the apparatus illustrated in FIG. 1; FIG. 3 is a perspective and sectional view of the perforated support and receptacle illustrated in FIG. 2, with an enlarged part, FIG. 4 is a front perspective view of the apparatus illustrated in FIG. 1, in which the enclosure for receiving food to be cooked and / or heated is in open configuration, the receptacle illustrated in FIGS. 2 and 3; having been removed, FIG. 5 is a rear perspective view of the apparatus illustrated in FIG. 4, in which a housing member has been removed to show a portion of the steam circulation; FIG. 6 is a front perspective view. of the apparatus illustrated in FIG. 4, in which the receptacle illustrated in FIGS. 2 and 3 is in place, showing the injection of vapor into the enclosure; FIG. 7 is a comparative diagram showing the temperature rise in the enclosure, with steam injection and without steam injection, - Figure 8 is a partial rear perspective view of the apparatus shown in Figure 1, showing air exhaust openings, - Figure 9 is a comparative diagram showing the rise in temperature in the enclosure, with air evacuation and without air evacuation, - Figure 10 is a sectional and elevational view of the apparatus illustrated in Figure 1, showing a containment wall of the device e n idle configuration, Figure 11 is a sectional elevational view of the apparatus shown in Figure 1, showing the containment wall of the apparatus in working configuration under the action of steam. The apparatus for cooking and / or heating food shown in Figure 1 comprises a steam generator 1 and an enclosure 2 for receiving food to be cooked and / or heated. The enclosure 2 may have a closed configuration for cooking and / or heating the food, shown in FIG. 1, and an open configuration, shown in FIGS. 4, 5 and 6, in which the food can be put in place or removed. In the exemplary embodiment illustrated in the figures, the enclosure 2 is formed between a receptacle 40 and a lid 20. The receptacle 40 is designed to receive food to be cooked and / or heated. Preferably, the receptacle 40 is removable, to allow a table service. In the embodiment illustrated in the figures, the cover 20 is mounted to move on a main body 10. The cover 20 is for example pivotally mounted on the main body 10 along a substantially horizontal axis 21, as shown in FIG. The steam generating device 1 comprises a water reservoir 30 associated with a heating element 31. In the embodiment illustrated in the figures, the steam production device 1 is arranged below the enclosure 2. The steam generating device 1 is arranged in the main body 10. The water tank 30 is delimited by an annular rib 11 formed on a bottom 12 of an inner tank 13 of the main body 10. The heating element 31 is integrated in a heating plate 32. The heating element 31 and the heating plate 32 may belong to a heating base used in the kettles. The heating element 31 may for example have a power of 2000 W. The heating plate 32 is surrounded by the annular rib 11. An annular seal 14 is interposed between the heating plate 32 and the annular rib 11. The heating plate 32 thus forms the major part of the bottom of the water tank 30. As shown in Figure 2, the receptacle 40 has two handles 41 arranged in opposite manner. The handles 41 are from an upper edge 42 of the receptacle 40. As seen in Figure 6, the handles 41 extend outside the apparatus. The handles 41 extend between the main body 10 and the lid 20. This arrangement facilitates the obtaining of cold handles. Alternatively or in addition, the receptacle 40 and / or the handles 41 may be made of low heat conducting material, for example plastic or stainless steel. Preferably, the receptacle 40 comprises at least one juice recovery space 45. As seen in Figures 2 and 3, the bottom of the receptacle 40 has an elevated portion 43. A peripheral annular groove 44 surrounds the raised portion 43 of the bottom of the receptacle 40 and forms the juice recovery space 45. As shown in Figure 1, the receptacle 40 is fitted into the main body 10. The upper rim 42 of the receptacle 40 rests on an inner rim 15 of the main body 10 , better visible in Figure 4. Thus the space between the receptacle 40 and the main body 10 remains confined. The internal rim 15 of the main body 10 is extended by notches 16 provided for the passage of the handles 41 of the receptacle 40. FIG. 2 also shows a perforated support 50 intended to be used with the receptacle 40. As represented in FIG. the receptacle 40 carries the removable perforated support 50. The juice recovery space 45 is arranged below a perforated portion 51 of the perforated support 50. The perforated support 50 rests on the raised portion 43 of the receptacle 40 and extends above the peripheral annular groove 44. perforated support 50 comprises a perforated portion 51 arranged above the peripheral annular groove 44 forming the juice recovery space 45. The perforated support 50 comprises a non-perforated portion 52 arranged above the raised portion 43 of the bottom of the receptacle 40 Thus, the juice recovery space 45 is annular and extends around the raised portion 43 of the bottom of the receptacle 40 exposed to the vapor stream from the steam generating device 1. As can be seen in FIG. receptacle 40 is carried by the main body 10. The receptacle 40 is removably mounted relative to the main body 10. The raised portion 43 of the bottom of the receptacle 40 extends above the heating element 31 Thus, the non-perforated portion 52 of the perforated support 50 is arranged above the heating element 31 and the water reservoir 30. In the embodiment illustrated in the figures, the cover 20 is mounted to move relative to the body primary 10 between a raised position for placing food in the receptacle 40 and / or removal of food from the receptacle 40, illustrated in Figures 4, 5 and 6 and a lowered position for cooking and / or heating the food arranged in the receptacle 40, illustrated in Figure 1. The main body 10 comprises for this purpose at least one unlocking member 17 associated with a fastening member (not shown in the figures), provided to come with a retaining member 26 belonging to the lid 20.
    [0010] The apparatus for cooking and / or heating food comprises a vapor expansion chamber 3 supplied with steam by the steam generating device 1. The vapor expansion chamber 3 is adjacent to the enclosure 2. In the embodiment shown in the figures, the vapor expansion chamber 3 is arranged above the chamber 2. More particularly, the vapor expansion chamber 3 is arranged in the cover 20. In other words , the lid 20 carries the vapor expansion chamber 3. The vapor expansion chamber 3 comprises a confinement wall 4 partially delimiting the chamber 2. The confinement wall 4 is deformable and / or mobile. Moreover, in the exemplary embodiment illustrated in the figures, the enclosure 2 is partially delimited by the removable receptacle 40. In the embodiment illustrated in the figures, the cover 20 has an outer shell 22 preferably articulated on the main body 10, and a lower shell 23 forming a cavity 24 having a lower opening. The containment wall 4 is carried by the cover 20. The confinement wall 4 is arranged under the lower shell 23 and thus delimits with the lower shell 23 the vapor expansion chamber 3. The confinement wall 4 is arranged above of the receptacle 40. The lid 20 carries a sealing ring 35 bearing on an upper edge 42 of the receptacle 40. Thus the sealing ring 35 belongs to a part of the chamber 2 movable relative to the receptacle 40. The periphery of the confinement wall 4 is inserted between the sealing ring 35 and the cover 20.
    [0011] The enclosure 2 is thus delimited by the receptacle 40, the sealing ring 35 and the confinement wall 4. The confinement wall 4 is movable relative to the receptacle 40 when the cover closes the enclosure 2. According to a form of preferred embodiment illustrated in the figures, the confinement wall 4 is in the form of a sheet of flexible material that is elastically deformable. The containment wall 4 is advantageously made of FEP (fluorinated ethylene-propylene copolymer, or tetrafluoroethylene perfluoropropylene), this material has the advantage of being less sensitive to the impregnation of food odors than silicones. As can be seen in FIG. 1, the confinement wall 4 has a rest position at least partially retracted inside the cover 20. Thus, the confinement wall 4 has a rest position at least partially concave with respect to the enclosure 2. In the exemplary embodiment illustrated in the figures, the vapor expansion chamber 3 is supplied with steam from the steam production device 1 by at least a first duct 65 formed in the main body 10, connecting a lower part of the main body 10 below the receptacle 40 at an upper part of the main body 10 outside the inner flange 15 of the main body 10 carrying the receptacle 40, said first duct 65 being connected to a second duct 66 formed in the cover 20, connecting a lower part of the cover 20 to the outside of the confinement wall 4 to an internal face of the cover 20 inside the confinement wall 4, As can be seen in FIGS. 10 and 11. According to a preferred embodiment, the enclosure 2 comprises at least one inlet opening 5 communicating with the steam production device 1 for injecting steam into the enclosure 2. Tests illustrated in FIG. 7 show that the rise in temperature in the enclosure 2 is faster when steam is admitted into the enclosure 2, than in the absence of vapor admitted into the enclosure 2 (to reach 100 ° C, 3 min against 8 min).
    [0012] The curve 71 represents the temperature evolution in the chamber 2 in the absence of steam. The curve 72 represents an evolution in the chamber 2 when steam is admitted into the chamber 2. In the embodiment shown in the figures, the inlet opening or openings 5 are arranged in the receptacle 40. Tel 3, an inlet opening 5 is arranged above the perforated support 50. As can be seen in FIGS. 4 and 5, the main body 10 has a lower lateral opening 60 arranged below the receptacle 40 and a upper lateral opening 61 arranged facing the inlet opening 5 arranged in the receptacle 40. The lower lateral opening 60 is connected to the upper lateral opening 61 by a transfer conduit 62 arranged in the inner wall of the main body 10, as shown diagrammatically in FIG. 5. To avoid washing the food with steam, the inlet opening (s) 5 can be closed off by the confinement wall 4 during that the vapor expansion chamber 3 is supplied with steam by the steam generating device 1. Thus, the confinement wall 4 displaced by the steam present in the vapor expansion chamber 3 can occupy at least one position closing the or alternatively, the inlet openings 5. Alternatively, the transfer conduit 62 may comprise a solenoid valve 63 for controlling the admission of vapor into the enclosure 2 independently of the admission of steam into the expansion chamber of the chamber. Vapor 3, as shown in Figure 5. According to a preferred embodiment, the chamber 2 has at least one discharge opening 6 communicating with the outside of the device. Of the 15 tests illustrated in Figure 9 show that the temperature rise of the food is faster if the air is expelled from the enclosure 2. The curves 73 and 74 represent the temperature evolution in a food when the air is The curves 75 and 76 represent the temperature evolution in a food in the absence of expulsion of the air from the enclosure 2. To avoid thermal leaks after the air has removed from the chamber 2, the evacuation opening or openings 6 can be closed by the confinement wall 4 when the vapor expansion chamber 3 is supplied with steam by the steam generating device 1. Thus the wall containment 4 displaced by the steam present in the vapor expansion chamber 3 can occupy at least one position closing the evacuation opening or openings 6. In the embodiment shown in the figures, the opening or openings of evacuation 6 are provided FIG. 8 shows two discharge openings 6 formed in the sealing ring 35 at the hinge of the cover 20. FIG. 10 shows an evacuation opening 6, communicating with the outside the device. In the configuration of Figure 11, the containment wall 4 extends into the receptacle 40 and closes the opening or openings 5 and the discharge or openings 6 (not visible in Figure 11). The perforated support 50 is not shown in FIGS. 10 and 11, but can be put in place in the receptacle 40 if desired. The apparatus comprises control means 7 for controlling the production of steam of the steam generating device 1 as a function of the vapor pressure prevailing in the vapor expansion chamber 3. In the embodiment illustrated in FIGS. FIGS., the control means 7 comprise a low pressure switch measuring the pressure in the vapor expansion chamber 3. The pressure switch is coupled to a contactor for controlling the power supply of the heating element 31. The pressure switch has a high threshold, for example 4 mbar, and a low threshold, for example 2.5 mbar. As long as the pressure in the vapor expansion chamber 3 remains below the high threshold, the heating element 31 is electrically powered. If the pressure in the vapor expansion chamber 3 exceeds the high threshold, the power supply to the heating element 31 is interrupted. The power supply of the heating element 31 remains interrupted as long as the pressure in the vapor expansion chamber 3 remains above the low threshold. If the pressure in the vapor expansion chamber 3 falls below the low threshold, the heating element 31 is electrically powered again. Alternatively, the control means 7 may in particular comprise a temperature sensor arranged to measure the temperature inside the vapor expansion chamber 3, in order to control the power supply of the heating element 31. and / or driving a solenoid valve to regulate the pressure inside the vapor expansion chamber 3.
    [0013] A safety valve 8 may be provided for communicating the vapor expansion chamber 3 with the outside in case of overpressure. In the embodiment illustrated in the figures, the safety valve 8 is mounted on the cover 20.
    [0014] The apparatus according to the invention operates and is used in the following manner: The user opens the chamber 2, fills the water tank 30 and places the food in the enclosure 2. The user can arrange the food in the receptacle 40 in place in the enclosure 2. The user can also place in the chamber 2 the receptacle 40 containing the food. If desired the user can place food on the perforated support 50 disposed in the receptacle 40. After closing the enclosure 2, the user can operate the device. The heating element 31 is then electrically powered. The steam production device 1 begins to produce steam which is directed in the vapor expansion chamber 3 on the one hand, and in the chamber 2 by the opening or openings 5. 5 steam progressively fills the vapor expansion chamber 3. The vapor present in the vapor expansion chamber 3 tends to deform the confinement wall 4 towards the enclosure 2. The vapor admitted into the enclosure 2 through the opening or openings of the admission 5 tends to expel the air present in the chamber 2 by the or the discharge openings 6, as shown in Figure 10. The containment wall 4 deformed towards the chamber 2 closes the first or the evacuation openings 6, reaching the sealing ring 35. The confinement wall 4 deformed towards the chamber 2 then closes the inlet opening or openings 5, reaching the upper portion of the receptacle 40. The confinement wall 4 deformed towards the enclosure 2 comes to wrap the upper part of The food placed in the chamber 2, which improves the heat transfer between the containment wall 4 heated by the steam present in the vapor expansion chamber 3 and the food present in the chamber 2. As the pressure to the interior of the vapor expansion chamber 3 remains below the high threshold, the heating element 31 remains electrically powered. This operating phase is a preheating phase, or phase of rise in temperature. When the pressure inside the vapor expansion chamber 3 exceeds the high threshold, the power supply of the heating element 31 is cut off until the pressure inside the expansion chamber Steam 3 reverts below the low threshold and then reestablishes until the pressure inside the vapor expansion chamber 3 returns above the high threshold and so on. This other operating phase is a heating and / or cooking phase, or regulation phase, using the pressure prevailing inside the vapor expansion chamber 3 to control the power supply of the heating element 31 Controlling the vapor pressure in the vapor expansion chamber 3 avoids exerting too much pressure on the food. When the perforated support 50 is used, the cooking juices can be collected in the juice recovery space 45 of the receptacle 40. When the desired cooking and / or heating time of the food is reached, the power supply of the heating element 31 is interrupted. This interruption can be performed manually by the user or automatically by a timer or by a cooking program. The user can then open the chamber 2 to remove the heated and / or cooked food. If desired, the user can grasp the receptacle 40 by the handles 41 extending outside the apparatus, and remove it from the apparatus, to prevail on the table.

More preferably, the method comprises controlling the 3. Advantageously, the process consists in limiting the pressure in the vapor expansion chamber 3 to a value of less than or equal to 10 millibars, and preferably less than or equal to 5 millibars. The invention also relates to an apparatus for cooking and / or heating food having control means for controlling the production of steam of the steam producing device 1 by using the method according to at least one of the above-mentioned features. In the exemplary embodiment illustrated in FIGS. 1 to 11, the control means comprise the pressure switch associated with the heating element 31.
    [0017] As a variant, the confinement wall 4 is not necessarily made entirely of resiliently deformable flexible material. The containment wall 4 may be at least partially made of resiliently deformable flexible material. In particular, the containment wall 4 may comprise at least one rigid part, and / or several parts or portions of different rigidity. As a variant, the confinement wall 4 does not necessarily have a concave rest position relative to the enclosure 2. The confinement wall 4 may in particular have a rest position at least partially concave with respect to the enclosure 2. The containment wall 4 may also come into contact with the food present in the chamber 2 before the steam is admitted into the vapor expansion chamber 3. Alternatively, the juice recovery space 45 of the receptacle 40 is not necessarily annular.
