Description

Title of the invention: Cooling receptacle for a food preparation appliance. Technical field

[0001] The present invention relates to the field of food preparation appliances and more specifically to a receptacle for cold food preparations such as ice cream, sorbets or frozen yogurts, said receptacle being able to be housed in a removable manner in a bowl of a food preparation appliance and to receive the ingredients of the cold food preparation in order to cool them during their processing and to result in said cold food preparation. State of the art

[0002] Food preparation appliances for preparing cold food are already known to those skilled in the art. Australian patent applications AU2020100186 and AU2020100187 are particularly well known, describing a food preparation appliance comprising a body with a base and a head extending above the base. The head can receive a food processing tool and includes a drive system for the food processing tool. The food preparation appliance also includes a bowl that engages with the base and a receptacle that fits removably into the bowl.The head can be positioned either in an engaged position, where the food processing tool fits into the receptacle placed in the bowl and is able to scrape the receptacle's inner wall during rotation, or in a disengaged position, where the food processing tool is away from the top of the bowl, allowing the receptacle to be removed. The receptacle forms a container into the upper part of which food preparation ingredients and the food processing tool can be placed. The receptacle includes a cooling inner shell with an annular wall and a base defining the container. The receptacle includes an outer shell in which the inner shell is positioned with a gap, this gap defining a sealed chamber containing refrigerant liquid to keep the inner shell cold for a certain period.

[0003] During use, the receptacle is placed in a freezer compartment of a refrigeration appliance, more commonly referred to as a freezer or a refrigerator equipped with such a freezer compartment, so as to cool the refrigerant liquid in the sealed chamber. Once ready for use, the receptacle is removed from the freezer compartment and placed in the bowl of the food preparation appliance. The ingredients placed in the receptacle come into contact with the refrigerated inner shell, their processing using the culinary processing tool allowing the obtaining of the cold culinary preparation.

[0004] The main disadvantage of this receptacle design described in Australian patent applications AU2020100186 and AU2020100187 is that it is bulky, requiring sufficient space in the freezer compartment to be placed there. Summary of the invention

[0005] The present invention overcomes the aforementioned drawback. To this end, the invention relates to a receptacle for cold culinary preparations such as ice cream, sorbet, or frozen yogurt. The receptacle is designed to be removably housed in a bowl of a food preparation appliance to form a container into the upper part of which ingredients for the culinary preparation and a food processing tool can be introduced. According to the invention, the receptacle comprises a cooling base and an annular wall removably mounted on the cooling base. The cooling base comprises an upper surface and an annular contour. An assembly system is arranged between an outer face of the annular contour and an inner face of the annular wall.The assembly system is configured, on the one hand, to allow a tight lock between the outer face and the inner face when the cooling base is introduced into the annular wall, so that the upper surface and the inner face define said container once the receptacle is formed and, on the other hand, to allow unlocking of the outer face and the inner face so as to be able to separate the cooling base from the annular wall once the receptacle is extracted from the bowl.

[0006] Thus, during use, the receptacle allows the cooling base to be separated from the annular wall so that only the cooling base can be placed in the freezer compartment of a refrigeration appliance. Once the cooling base is ready for use, after remaining in the freezer compartment for a sufficient time, for example, approximately eighteen hours, the user can reassemble the cooling base and the annular wall to reconstitute the container and place it in the bowl of the food preparation appliance.When the receptacle is not in use, i.e. when the bowl is used alone for food preparations other than cold food preparations, the cooling base can be detached from the annular wall while remaining housed in the annular wall, which allows the height of the assembly (receptacle detached) to be reduced to the height of the annular wall, if the height of the latter is greater than that of the cooling base, or to the height of the cooling base, if, conversely, the height of the latter is greater than that of the annular wall.

[0007] According to one embodiment of the receptacle of the invention, the upper surface is flat. However, alternative embodiments of the receptacle are possible with a non-flat upper surface, for example, a concave or convex upper surface. The shape of the flat surface will depend on the shape and movements of the processing tool moving within the container during the processing of the ingredients for the culinary preparation, or conversely, will determine the shape and movements of said processing tool.

[0008] Preferably, according to the aforementioned embodiment of the receptacle of the invention, the upper surface forms a disk defined in a plane perpendicular to a median axis of the cooling base. Other shapes of the upper surface remain conceivable, for example an oval or elliptical shape defined in a plane perpendicular to a median axis of the cooling base.

[0009] According to one embodiment of the receptacle of the invention, the annular wall comprises at least one gripping member. This will facilitate the positioning of the receptacle in the bowl and, conversely, its removal from said bowl. Preferably, the annular wall comprises two diametrically opposed gripping members, which will allow the receptacle to be manipulated with both hands while holding it securely, without risk of spilling the cold food preparation out of the receptacle when the receptacle is removed from the bowl.

[0010] According to one embodiment of the receptacle of the invention, the cooling base comprises a part made of a thermally conductive material, preferably aluminum, the part comprising the upper surface. Furthermore, the cooling base comprises a housing made of a plastic material resistant to the negative temperatures encountered in freezers, for example polyethylene (PE), polypropylene (PP), polyamide (PA), or acrylonitrile butadiene styrene (ABS), provided with a top opening, said part being configured to close said top opening. In addition, the cooling base comprises a phase-change material contained within the housing.Preferably, the component includes fins on its underside, housed within the enclosure and extending into the phase-change material. These fins promote homogeneous heat transfer between the component and the phase-change material, ensuring that the cold food being processed in the container cools uniformly. Preferably, the enclosure includes a base on its underside, equipped with pads. These pads are designed to contact the bottom of the bowl when the receptacle is inserted into the bowl. Preferably, these pads are made of rubber or silicone. These pads ensure proper positioning of the upper surface when the receptacle is inserted into the bowl, thus preventing stress on the processing tool during activation due to incorrect positioning of the upper surface. These pads... They also ensure perfect contact between the processing tool and the upper surface by compressing slightly to absorb the force exerted by the processing tool on the upper surface. Furthermore, these pads also ensure perfect adhesion of the receptacle placed on the bottom of the bowl, preventing it from rotating within the bowl during the activation of the processing tool.

[0011] According to one embodiment of the receptacle of the invention, the assembly system comprises, on the outer face of the annular contour, an outer shoulder and a groove, and, on the inner face of the annular wall, an inner shoulder adapted to receive the outer shoulder as support when the cooling base is inserted into the annular wall, and an engagement device comprising at least one protruding element adapted to engage in the groove when the outer shoulder comes into contact with the inner shoulder. Furthermore, the engagement device comprises means for returning at least one protruding element to the engaged position in the groove and at least one control member configured to disengage at least one protruding element from the groove. Other embodiments of the assembly system remain conceivable within the scope of the invention.

[0012] The invention also relates to a food preparation apparatus, which comprises a body having a base and a head extending above the base. The apparatus also includes a bowl configured to be engaged on the base, the head being configured to receive a food processing tool and comprising a drive system for the food processing tool in a planetary motion. Furthermore, the apparatus includes a receptacle having at least the aforementioned essential characteristics of the invention. The receptacle is configured to fit snugly around the bowl when it is inserted into the bowl.The head is configured to be moved into an engaged position where the food processing tool fits into the receptacle container placed in the bowl and is able to scrape the upper surface when it is set in planetary motion, or into a disengaged position where the food processing tool is away from the top of the bowl, allowing the receptacle to be removed from the bowl.

[0013] According to one embodiment of the food preparation appliance of the invention, the head is mounted to pivot relative to the body so as to pivot from the engaged position to the disengaged position, and vice versa. A variant could be envisaged with a head mounted to translate vertically relative to the body so as to translate into the engaged or disengaged position.

[0014] According to one embodiment of the food preparation apparatus of the invention, the upper surface of the cooling base is flat and forms a disk perpendicular to an axis of rotation of the food processing tool. Furthermore, the processing tool culinary includes a blade arranged perpendicular to the axis of rotation and scraping the disc during its planetary motion. Brief description of the figures

Detailed description

[0016] In the remainder of this description, unless otherwise indicated, the term "apparatus" refers to the food preparation apparatus that is the subject of the invention. Similarly, unless otherwise indicated, the term "tool" refers to the food processing tool.

[0017] In the following description, terms such as "horizontal", "vertical", "lower", "upper", "high", "lower"... which may be used, will be used in consideration of the normal position of the device, the bowl or the receptacle, resting in use on a horizontal work surface, for example a table or a kitchen worktop.

[0018] Figures [Fig. 1], [Fig. 2], and [Fig. 3] illustrate an embodiment of the apparatus 100 comprising a body 103, a head 105, a bowl 101 positioned on a base 104 of the body 103, and a tool 200 mounted on the head 105 and housed in the bowl 101. The head 105 is pivotally mounted relative to the body 103 by means of a hinge 110, which allows the head 105 to be tilted in the direction of the double arrow Fl illustrated in [Fig. 2] to be placed either in an engaged position where the tool 200 is located in the bowl 101 and can be activated to perform culinary processing on ingredients placed in the bowl 101, or in a disengaged position where the tool 200 is located outside the bowl 101 to access it and possibly remove it from the base 104 of the device 100 or remove what is contained in said bowl 101.

[0019] The activation of the tool 200 is achieved by means of a drive system 106 which is arranged on the head 105 and configured to generate a planetary motion of the tool 200, which rotates about itself around a first axis XI of rotation, said first axis XI also rotating about a second axis X2 of rotation. The drive system 106 includes a rotation shaft 108 which extends longitudinally along the first axis XI and rotates about said first axis X. This rotation shaft 108 is coupled to the tool 200, as will be explained later. The bowl 101 is closed by a lid 111 which includes a central opening 112 allowing the passage of the tool 200 and a part 113 of the head 105 comprising the drive system 106, as shown in [Fig.2], when the head 105 is positioned in the engaged position.The lid 111 also includes a spout 114 with an opening 115 allowing the introduction of ingredients for a culinary preparation when the lid 111 is placed on the bowl 101.

[0020] The appliance 100 is designed to make various types of food preparations, including cold food preparations such as ice cream, sorbet, or frozen yogurt. For this purpose, the appliance 100 includes a receptacle 1 and a tool 200 specially adapted for making such cold food preparations. The receptacle 1 is configured to be removable from the bowl 101 so that it can be removed and the bowl 101 can be used for other types of food preparations that do not require the receptacle 1. including other culinary processing tools than tool 200 illustrated and described below.

[0021] Figures 5 to 13 detail a preferred design of the receptacle 1. The receptacle 1 comprises a cooling base 4 and an annular wall 5 which, when assembled using an assembly system 8, define a container 2. The upper part of the container 3 has an opening 35 allowing the introduction of ingredients for the cold culinary preparation to be made, as well as the insertion of the tool 200 into the container 2. When the receptacle 1 is formed, it can be placed in the bowl 101, as shown in particular in Figures 6 and 8. To facilitate handling of the receptacle 1, it has two diametrically opposed gripping members 11. The bowl 101 also has two diametrically opposed gripping members 117 to facilitate its handling.

[0022] With particular reference to [Fig. 9] to [Fig. 11], the cooling base 4 comprises a part 12 and a housing 13. The part 12 is made of a material with good thermal conductivity, preferably aluminum, although other materials with good thermal conductivity may be considered. The part 12 comprises an upper surface 6 which is preferably flat and has the shape of a disk 18, although other shapes may be considered, for example, an oval or elliptical shape. This disk 18 is defined in a plane perpendicular to a median axis X0 of the cooling base 4. The part 12 comprises on its lower face 25 fins 15 spaced apart and distributed uniformly below said lower face 25 extending radially and downwards, as shown in [Fig. 10].Part 12 includes first studs 26 distributed uniformly around the periphery of the disk 18, below the lower face 25, these first studs 26 having on their lower side 26a a tapped hole (not illustrated).

[0023] The enclosure 13 defines a basin that allows the reception of a phase-change fluid, preferably a liquid, although a slightly viscous fluid is also possible. Preferably, this fluid is a eutectic liquid. The enclosure 13 comprises an annular contour 7, which is delimited at its lower part by a base 16 and at its upper part by a rim 27 that defines a top opening 28. This rim 27 also defines, with the outer face 9 of the annular contour 7, an outer shoulder 19. The top opening 28 allows the fins 15 of the part 12 to be introduced into the enclosure 13, where they are immersed in the phase-change fluid (not shown) contained in said enclosure 13. The peripheral edge of the lower face 25 of the part 12 then rests against the rim 27. The annular contour 7 comprises a groove 20 on its outer face 9.

[0024] Second studs 29 extend upwards from an inner face 30 of the annular contour 7, these second studs 29 being the same number as the first studs 26 on the part 12 and arranged with the same distribution as said first studs 26. The second studs 29 are hollow and open onto orifices 31 on the outer face 9 of the annular contour 7. A through hole 32 on the second stud 29 allows the passage of a threaded body of an assembly screw (not illustrated) inserted from the orifice 31 and the stopping of the head of this assembly screw, the threaded body of the assembly screw passing through the through hole 32 to screw into a tapped hole on a first stud 26, once the part 12 is placed on the enclosure 13 as in [Fig.9]. A sealing gasket 33 is placed on the rim 27 to ensure a seal between the part 12 and the enclosure 13 once the cooling base 4 is formed.

[0025] The base 16 of the housing 13 comprises pads 17, preferably three in number, uniformly distributed, as shown in particular in [Fig. 5]. When the cooling base 4 is placed in the bowl 101, the pads 17 come into contact with the bottom 102 of the bowl 101, the annular wall 5 and the annular contour 7 conforming to the shape of the bowl 101, as shown in particular in [Fig. 8]. This makes it possible to keep the receptacle 1 static in the bowl 101, preventing said receptacle 1 from rotating in said bowl 101 when the tool 200 is activated in planetary motion. This also makes it possible to properly stabilize the receptacle 1 in the bowl 101, resting on the bottom 102.

[0026] With particular reference to [Fig. 7], [Fig. 12] and [Fig. 13], the annular wall 5 comprises an upper edge 34 defining a top opening 35 corresponding to that in the upper part 3 of the container 2 defined by the assembly of the annular wall 5 with the cooling base 4. The gripping members 11 extend upwards from the upper edge 34. The annular wall 5 also comprises a lower edge 36 defining a bottom opening 37. The annular wall 5 comprises an inner face 10 which has an internal shoulder 21.

[0027] An interlocking device 22 is arranged on the annular wall 5, below the internal shoulder 21. This interlocking device 22 preferably comprises two diametrically opposed control members 24 on the annular wall 5, each disposed in a window 38 arranged on the annular wall 5. Each control member 22 is connected to its respective window 38 by means of two attachment points 39a, 39b which define a pivot axis X3 extending perpendicularly to the median axis X0 of the cooling base 4, which is also the median axis of the annular wall 5. The control members 22 and the annular wall 5 are formed in one piece from a plastic material, for example polyethylene (PE) or polypropylene (PP), thus providing slight elasticity which allows the control members 22 to pivot around their pivot axes. X3 respectively by lightly pressing on said control elements 22. This pivoting of the elements control element 22 allows a twist to be applied to the attachment points 39a, 39b, the control elements 22 returning to their normal position thanks to the elasticity of the plastic material when pressure is no longer applied to said control elements 22, the attachment points 39a, 39b returning to their normal (untwisted) state due to the elasticity of the material.

[0028] These control elements 22 each comprise a protruding element 23 oriented towards the inner face 10 of the annular wall 5. The cooling base 4 is inserted from above into the annular wall 5, through the upper opening 35. The cooling base 4 then descends into the annular wall 5 and partially exits through the lower opening 37, until the outer shoulder 19 on the cooling base 4 bears against the inner shoulder 21 on the inner face 10 of the annular wall 5. During this insertion of the cooling base 4 into the annular wall 5, the protruding elements 23 on the control elements 22 bear against the outer wall 9 of the annular contour 7 of the cooling base 4, which causes the control elements 22 to pivot slightly about their axis of rotation X3 thanks to the elasticity of the material of the annular wall 5.When the outer shoulder 19 comes into contact with the inner shoulder 21, as described above, the protruding elements 23 align with the groove 20 on the outer face 10 of the annular contour 7. The elasticity of the material of the annular wall 5 then allows the protruding elements 23 to return to their normal (untwisted) position and enter the groove 20, thus locking the cooling base 4 against the annular wall 5, thereby forming the receptacle 1. Slight pressure on the control elements 22 disengages the protruding elements 23 from the groove 20, allowing the receptacle 1 to be removed. The cooling base 4 is then extracted from the annular wall 5 by lifting it upwards through the upper opening 34 of the annular wall 5.

[0029] The use of a plastic material for the annular wall 5 is sufficient to ensure a seal between the outer shoulder 19 on the cooling base 4 and the inner shoulder 21 on the annular wall 5, especially since the ingredients of the cold food preparation solidify during cooking. However, a sealing gasket could be added between said outer shoulder 19 and said inner shoulder 21.

[0030] With particular reference to [Fig. 2], [Fig. 4], [Fig. 9], and [Fig. 14], the tool 200 comprises a blade 201 that extends radially with respect to the first axis XI of rotation of said tool 200 mounted on the rotation shaft 108 of the drive system 106 of the head 105. This mounting of the tool 200 on the head 105 is achieved by means of a first coupling member 207 on the tool 200 cooperating with a second coupling member 107 on the rotation shaft 108, so as to block rotation about the axis XI and translation along said axis XI between said tool 200 and said shaft rotation 108. The tool 200 can be removed from the head 105 after use, for cleaning. Those skilled in the art can draw inspiration from existing food preparation equipment for implementing the first coupling member 207 on the tool 200 and the second coupling member 107 on the rotating shaft 108. For example, a pin 116 (see [Fig. 2]) can be provided on the rotating shaft 108. This pin 116 engages in a groove 208 and then in a cavity 209, both present on the tool 200 (see [Fig. 14]), thus blocking the translation and rotation of the tool 200 about axis XI relative to the rotating shaft 108. A spring 109, positioned on the rotating shaft 108 above the tool 200, pushes the tool 200 downwards, thereby holding the pin 116 in the cavity 209. This type of coupling is also known as the name "bayonet assembly".

[0031] Preferably, the tool 200 includes an adapter piece 210 which includes the first coupling member 207, the adapter piece 210 being removably mounted on an upper part 211 of the blade 201, as shown in particular in [Fig.4] and [Fig. 14]. This adapter piece 210 therefore includes the groove 208 and the cavity 209. The adapter piece 210 is assembled in a detachable manner with the blade 201. For this purpose, the adapter piece 210 includes a tubular part 212 which engages in an opening 213 on the upper part 211, an assembly mechanism (not shown), for example a bolt in the upper part 211 which engages in a strike plate on the tubular part 212 for locking between these parts, the bolt being actuated by a control button 214 to allow the unlocking of the adapter piece 210 vis-à-vis the blade 201.This advantageously allows the tool 200 to be adapted to various food preparation devices, each of which has its own adapter piece that can cooperate with the blade 201 and which has a first coupling element adapted to a second coupling element present on a rotation shaft of a drive system present on a head of the food preparation device.

[0032] With particular reference to [Fig. 4] and [Fig. 14], the blade 201 comprises, in its lower part, a blade 202 and a reinforcement structure 206 for the blade 202. This reinforcement structure 206 comprises a first reinforcement element 215 extending vertically between an edge 216 of the upper part 211 and an end 217 of the blade 202, and a second reinforcement element 218 extending obliquely between the upper part 211 and the blade 202, as shown in particular in [Fig. 4]. This reinforcement structure 206 contributes to the mixing of the ingredients of the cold food preparation during cooking, which allows for more efficient mixing and aeration of the cold food preparation, thus enriching it with small air bubbles.

[0033] With particular reference to [Fig.4], [Fig.9], [Fig.14] and [Fig.15], the blade 202 extends radially with respect to the first axis XI and comprises a first part 203 and a second part 204. The first part 203 is more or less distributed symmetrically with respect to the first axis XI and is extended at an end 205 by the second part 204 which is offset to one side of the first axis XL. A possible variant would be to position the first part 203 and the second part 204 on the same side of the first axis XI, the end 217 of the blade 202 being in this case arranged in alignment with the first axis XL. The first part 203 is offset upwards with respect to the second part 204 by a distance DI which, preferably, is between 0.5 mm and 3 mm, preferably between 1 mm and 2 mm. The first part 203 of the blade 202 extends over a length L1 between 35 mm and 42 mm, for example equal to 38 mm, and the second part 204 of the blade 202 extends over a length L2 between 40 mm and 45 mm, for example equal to 42 mm.Thus, the second part 204 of the blade 202 comes into contact with the upper surface 6 of the cooling base 4 and the first part 203 of the blade 202 remains slightly offset from said upper surface 6, by the distance DI. .

[0034] During the rotation of the tool 200 around the first axis XI and the second axis X2, generated by the planetary motion, the first part 203 of the blade 202 spreads and presses the ingredients of the food being prepared onto the upper surface 6, thus promoting their cooling. The second part 204 of the blade 202 scrapes the upper surface 6 to detach the cold food being prepared. The reinforcing structure 206 promotes the mixing and aeration of said cold food being prepared. The presence of the spring 109 allows the tool 200 to be pushed downwards, which promotes proper contact of the second part 204 with the upper surface 6.

[0035] As mentioned previously, the upper surface 6 is in the shape of a disc 18. The disc 18 has a diameter D which is preferably between 160 mm and 200 mm, for example 185 mm. Preferably, the second part 204 of the blade 202 and the diameter D of the disc 18 are dimensioned to maintain an L2 / D ratio of less than 0.3 in order to promote heat exchange between the cold food being prepared and the cooling base 4. Preferably, this L2 / D ratio is 0.25.

[0036] Variants are conceivable within the framework of the invention, i.e. with a receptacle 1 which includes a cooling base 4 and an annular wall 5 assembled together in a removable and sealed manner, by means of an assembly system 8 identical or comparable to that described above, other variants of the assembly system being possible.

[0037] For example, the tool 200 could have a blade whose entire length would be in contact with the upper surface 6 to scrape it, the blade in this case being entirely offset on one side of the first axis XI and not comprising a first part 203. The length of the blade in contact with the upper surface 6 to scrape it would then correspond to the length L2 of the second part 204 of the blade 202.

[0038] According to another example, the upper surface 6 of the cooling base might not be flat, for example, it might be concave, the tool 200 being adapted in this case to have at least one part that scrapes said concave shape of the upper surface 6 during the rotation of the tool in a planetary motion. This upper surface 6 could also be flat, but of a different shape than that of a disk 18, for example, an oval or elliptical shape.

[0039] A variant of the tool 200 is also possible without the adapter piece 210, in which case the first coupling member 207 is directly implemented on the upper part 211 of the blade 201.
