Description

Title of the invention: Culinary processing tool for cold culinary preparations. Technical field

[0001] The present invention relates to the field of food preparation equipment and more particularly to a food processing tool for making cold food preparations such as ice cream, sorbet, or frozen yogurt. Prior art

[0002] Food preparation appliances often include various food processing tools for making different types of food preparations. Among these appliances, some are suitable for making cold food preparations such as ice cream, sorbet, or frozen yogurt.

[0003] Such a food preparation apparatus for making cold dishes generally comprises a base, a head extending above the base, a container for holding the ingredients for the cold dish, the container having a chilled wall against which the ingredients come into contact during the preparation of the cold dish, and a food processing tool for scraping said chilled wall and mixing the chilled ingredients during said preparation of the cold dish. The chilled wall may consist of the bottom and optionally the sides of said container.The food processing tool is set in motion within the container by means of a drive system arranged on the head, which can be moved on the appliance either into an engaged position where the food processing tool is housed within the container and scrapes the refrigerated wall of said container, or into a disengaged position where the food processing tool is removed from the container to allow for disassembly and cleaning of the food processing tool, as well as removal of the container in order to extract the cold food preparation obtained and cleaning of said container.

[0004] Among food preparation equipment for making cold dishes, patent application FR2405685A1 is known, describing an ice cream maker comprising a head equipped with a system for driving a scraping blade in a planetary motion. The scraping blade has a lower scraping surface extending at a distance from an axis of rotation of the blade and comes into contact with a chilled base of a container that holds the ingredients for the cold dish. One of the advantages of the design described in this document FR2405685A1 is the ability to use containers of various shapes and to make cold culinary preparations of various shapes more attractive than a cylindrical block and free of ice crystals.

[0005] Although this design according to document FR2405685A1 has considerable advantages, the cooking processing time for obtaining the cold cooking preparation may prove to be high because the lower scraping face of the scraping blade sweeps at high frequency the entire surface of the chilled bottom of the container, which limits the heat exchange time between said chilled bottom and the ingredients of the cooking preparation, in contact with said chilled bottom during cooking processing. Summary of the invention

[0006] The present invention makes it possible to overcome this aforementioned drawback by implementing a culinary processing tool whose design promotes heat exchange between the refrigerated wall of the container and the ingredients of the cold culinary preparation, thus making it possible to reduce the processing time of the cold culinary preparation.

[0007] To this end, the invention relates firstly to a food preparation tool for cold culinary preparations such as ice cream, sorbet, or frozen yogurt, said food preparation tool being suitable for being housed in a bowl of a food preparation appliance and for coming into contact with an upper surface of a cooling base inside the bowl. This upper surface of the cooling base can be defined as the inner wall of the bowl, which, in this case, directly constitutes a container receiving the ingredients of the cold culinary preparation and the food preparation tool that comes into contact with said upper surface. Alternatively, this upper surface of the cooling base can be defined as a receptacle that is housed in the bowl and defines said container receiving the ingredients of the cold culinary preparation and the food preparation tool that comes into contact with said upper surface.

[0008] According to the invention, the food processing tool comprises a first axis and is adapted to be driven in rotation about the first axis and about a second axis parallel to the first axis and perpendicular to a plane of the upper surface, for the creation of a planetary motion of the food processing tool. Furthermore, the food processing tool comprises a blade that extends radially from the first axis. According to the invention, the blade has a cutting edge having a first part and a second part, the first part extending radially from the first axis and being continued by the second part, the second part being offset from the first axis and disposed at a distance DI below the first part.The first part is configured to be spaced away from the upper surface and to compact the food preparation onto the upper surface, and the second part is configured to scrape the upper surface during a planetary motion of the food processing tool.

[0009] This blade design advantageously allows the first part to be slightly spaced from the upper surface of the cooling base, which advantageously enables it to spread and compact the ingredients of the cold food being prepared on the upper surface of the cooling base during the planetary motion of the blade, thereby increasing the heat exchange between said upper surface and said ingredients. The second part of the blade scrapes said upper surface during the planetary motion to separate the cooled ingredients being processed from the upper surface and allow their mixing and the formation of the cold food preparation.

[0010] According to one embodiment of the culinary processing tool of the invention, the distance D1 is between 0.5 mm and 3 mm, preferably between 1 mm and 2 mm. This choice optimizes the spreading and compaction of the ingredients being processed on the upper surface of the cooling base during the planetary motion of the blade. Of course, other dimensions below 0.5 mm or above 3 mm remain possible, while remaining within the scope of the invention.

[0011] According to one embodiment of the culinary processing tool of the invention, the first part extends over a length L1 of between 35 mm and 42 mm and the second part extends over a length L2 of between 40 mm and 45 mm. This choice of lengths L1 and L2 optimizes the heat exchange time between the ingredients being processed and the upper surface of the cooling base during the planetary motion of the blade, resulting in faster processing of the cold food preparation. Of course, other lengths for the first and second parts of the blade remain possible, while remaining within the scope of the invention.

[0012] According to a preferred embodiment of the culinary processing tool of the invention, the first part extends radially on either side of the first axis, the second part extending from one end of the first part. This design allows for more efficient spreading and compaction of the ingredients being processed on the upper surface of the cooling base, forming discs on said upper surface. This also allows the processing tool to be used with a bowl of reduced diameter. Furthermore, it limits the projection of ingredients being processed towards the edge of the bowl, thus resulting in better compaction of said ingredients on the upper surface of the cooling base.Alternatively, the first part could extend radially from one side of the first axis and be extended at its end by the second part, this design allowing the ingredients being cooked to be spread and compacted on the upper surface of the refrigerated base, forming rings on said upper surface.

[0013] According to a preferred embodiment of the food preparation tool of the invention, the blade comprises a blade reinforcement structure, the reinforcement structure being configured to participate in the mixing of the food preparation during the planetary motion of said food preparation tool. Thus, the reinforcement structure promotes the incorporation of air during the mixing of the ingredients during food preparation, ultimately resulting in a better-aerated cold food preparation. A variant of the blade without a reinforcement structure remains conceivable, while remaining within the scope of the invention.

[0014] According to the invention, the food preparation tool comprises a first coupling member adapted to be assembled with a second coupling member of a rotating shaft on the food preparation appliance. In a preferred embodiment, the food preparation tool comprises an adapter piece, an assembly system being arranged between the adapter piece and the blade and configured to removably assemble the adapter piece and the blade along the first axis, said adapter piece comprising the first coupling member. This advantageously allows the same blade to be used on different designs of a food preparation appliance, each of which will have an adapter piece adapted to be assembled with the blade and comprising a first coupling member compatible with the rotating shaft according to the design of said food preparation appliance.

[0015] The invention also relates to a food preparation apparatus, which comprises a body having a base, a head extending above the base, a bowl receiving a cooling base having a top surface, the bowl being configured to be engaged on the base of the apparatus, and a food processing tool having at least the aforementioned essential characteristics. The head comprises a drive system for the food processing tool in a planetary motion, the head being configured to be moved into an engaged position where the food processing tool is housed in the bowl and the second part of the blade scrapes the top surface during its planetary motion, or into a disengaged position where the food processing tool is away from the bowl and the top surface.

[0016] According to the food preparation apparatus of the invention, the food processing tool comprises a first coupling member, and the drive system comprises a rotating shaft having a second coupling member complementary to the first coupling member. In a preferred embodiment, the second coupling member comprises a spring configured to press the second part of the blade against the upper surface of the cooling base when the head is in the engaged position. This spring compensates for play. of the assembly that may exist between the first coupling element and the second coupling element and also due to the assembly between the head and the body, in order to ensure that the second part of the blade is properly in contact with the upper surface of the cooling base during cooking.

Detailed description

[0018] 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.

[0019] 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.

[0020] 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.

[0021] 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.

[0022] 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 being configured to be removably inserted into the bowl 101. in order to allow its removal and to use the bowl 101 for the preparation of other types of food preparations not requiring the presence of said receptacle 1, the appliance 100 comprising other food processing tools than the tool 200 illustrated and described below.

[0023] 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 a fastening 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.

[0024] With particular reference to [Fig. 9] to [Fig. 11], the cooling base 4 comprises a Part 12 and an enclosure 13. Part 12 is made of a material with good thermal conductivity, preferably aluminum, although other materials with good thermal conductivity may be considered. Part 12 includes an upper surface 6 which is preferably flat and has the shape of a disc 18, although other shapes may be considered, for example, an oval or elliptical shape. This disc 18 is defined in a plane perpendicular to a median axis X0 of the cooling base 4. Part 12 includes 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).

[0025] 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 external 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 edge The peripheral part of the lower face 25 of the part 12 then rests on the rim 27. The annular contour 7 includes on its external face 9 a groove 20.

[0026] 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.

[0027] 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.

[0028] 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.

[0029] 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 interlocking device to pivot. the control elements 22 around their respective pivot axes X3 by applying slight pressure to said control elements 22. This pivoting of the control elements 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 released from said control elements 22, the attachment points 39a, 39b returning to their normal (untwisted) state due to the elasticity of the material.

[0030] 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.

[0031] 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.

[0032] With particular reference to [Fig. 2], [Fig. 4], [Fig. 9] and [Fig. 14], the tool 200 comprises a blade 201 which 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 member coupling 107 on the rotation shaft 108, so as to block rotation around axis XI and translation along said axis XI between said tool 200 and said rotation shaft 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, said pin 116 engaging in a groove 208 and then in a cavity 209, present on the tool 200 (see [Fig. 14]) to block the translation and rotation about the axis XI of the tool 200 relative to the rotating shaft 108. A spring 109 placed on the rotating shaft 108, above the tool 200, allows the tool 200 to be pushed downwards and thus holds the pin 116 in the cavity 209.This type of coupling is also known as a "bayonet fitting".

[0033] 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.

[0034] 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.

[0035] 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 distributed more or less symmetrically with respect to the first axis XI and is extended at one end 205 by the second part 204, which is offset to one side of the first axis XL. A possible alternative 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 aligned 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.

[0036] 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.

[0037] 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.

[0038] Variants are conceivable within the framework of the invention, i.e. with a tool 200 which includes a blade 202 comprising a first part 203 and a second part 204, the first part 2023 being offset upwards relative to the second part 204 by a distance DI.

[0039] For example, the bowl 101 could directly receive the cooling base 4, without the annular wall 5, that is to say without constituting a receptacle 1 as described Previously, in which case the ingredients would be placed directly into bowl 1 to come into contact with the upper surface 6 of the refrigerating base 4.

[0040] According to another example, the blade 201 of the tool 200 could have a blade without the reinforcement structure 206 described previously, or with a reinforcement structure arranged differently.

[0041] 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.
