Technical Field

[0003] This utility model belongs to the field of food processing electrical appliances, specifically relating to a food processing sub-component and a food chopper. The food processing sub-component is configured into a food processor to achieve the function of mincing meat. Background Technology

[0004] A food processor is an appliance that uses a motor to drive blades to rotate at high speed to chop food. Some manufacturers also call it a high-speed blender. It is generally equipped with a heating element, such as a heating plate located at the bottom of the container. Food processing is achieved through the heating element and the blade's chopping function. Generally speaking, existing food processors use high speed to chop food. Because the blades of food processors are relatively low, it is usually necessary to add a fluid such as water to chop the food materials.

[0005] Food processors are generally not well-suited for tasks requiring a specific level of fineness, such as mincing meat, chopping seasonings, or preparing fillings. They are also difficult to clean, prone to leaving food residue, which can cause unpleasant odors and potential hygiene problems. Therefore, for tasks like mincing meat, chopping seasonings, and preparing fillings, a meat grinder is needed. Meat grinders have a lower output speed than food choppers but higher torque. Their blades are typically multi-layered, allowing them to process more ingredients at once, and the blades are detachable for easy cleaning.

[0006] For the reasons mentioned above, people need to purchase multiple devices, which is costly and takes up a lot of space. Summary of the Invention

[0007] The present invention aims to solve the problem that the existing technology requires the purchase of multiple devices for food preparation and chopping of ingredients into specific fineness or non-fluid processing, which is costly and space-consuming. This application solves the problem by designing a sub-processing component that can be selectively installed and detachably coupled to the drive mechanism of the food processor to achieve non-fluid chopping processing.

[0039] The specific embodiments of the present application will be described below with reference to the accompanying drawings:

[0040] Referring to Figures 1 to 4 The present application relates to a food processor and a food processor sub-assembly in general, and more particularly to a detachable coupling for realizing a rotary transmission, such as a detachable transmission coupling between the input end 5.1 of the speed reducer 5 and the output end 3.1 of the driving mechanism 3, i.e., the input end 5.1 of the speed reducer 5 and the output end 3.1 of the driving mechanism 3 are detachably and circumferentially connected with a positioning function, such as a square shaft and a square hole, or a polygonal shaft and a polygonal hole, or a keyhole and a shaft, or other transmission matching structures in the art. The transmission coupling can be a detachable coupling as described above, or a fixed connection.

[0041] The sub-knife k2 is a knife that can shred food into larger particles, such as ground meat. Generally, it needs to be equipped with multiple blades, such as two or more layers. Of course, the number of blades can be adjusted according to actual needs. In some embodiments, it can also be a single layer. In addition, regarding the use of the sub-assembly b, the protection scope of the present application is not limited to ground meat and other uses that require separate processing with the assembly a. For example Figure 10 As shown, the sub-knife k2 includes a knife body k2' and a blade k2.1' arranged on the body k2'. The sub-knife k2 is arranged in the sub-assembly b, and the sub-assembly b is arranged in the assembly a. Figure 10 The embodiment shown is equipped with two layers of blades k2.1'. In other embodiments, it can be equipped with one layer or three layers or more. Regarding the assembly of the blade k2.1' and the body k2', the body k2' can be injection molded in parts and then assembled with the blade k2.1', such as interference fit, threaded connection, and other common methods in the art. Alternatively, the blade k2.1' and the body k2' can be injection molded together. Of course, it can also use related structures in the shredder, such as a meat grinder.

[0042] Referring to Figures 1 to 8 In some embodiments, the food shredder includes an assembly a and a sub-assembly b. The assembly a includes a cup assembly 1 having a first upper end opening 10 of a cooking cavity 100, a cover 2 for opening and closing the first upper end opening 10 of the cooking cavity 100, a drive mechanism 3 arranged on the lower side of the cup assembly 1, including a drive motor, and a knife k1 arranged at the bottom of the cooking cavity 100 and transmission coupled with the drive mechanism 3. The sub-assembly b is detachably assembled in the cooking cavity 100 and includes a sub-cup assembly 4 having a second upper end opening 40 of a sub-cooking cavity 400, a sub-knife k2 arranged in the sub-cooking cavity 400, and a speed reducer 5 arranged on the lower side of the sub-cup assembly 4, including a speed reduction mechanism 50, an input end 5.1 of the speed reducer 5, and a speed reducer output end 5.2. The input end 5.1 of the speed reducer 5 is used for detachable transmission coupling with the drive mechanism 3, and the sub-knife k1 is transmission coupled with the speed reducer output end 5.2.

[0043] The speed reduction mechanism 50 of the present application can be a gear train speed reduction mechanism, such as a set of gears with different transmission ratios to achieve speed reduction. It can include a combination of double gears and single gears, a combination of multiple double gears, or a combination of multiple single gears. Alternatively, it can be achieved by a planetary speed reduction mechanism. Such a speed reduction mechanism can be implemented according to the known speed reduction mechanisms.

[0044] The food chopper of the present application can process food through the cooking assembly a. When the food needs to be chopped into larger particles, the cooking subassembly b is assembled into the cooking cavity 100, and the input end 5.1 of the speed reducer 5 is transmissionally coupled with the driving mechanism 3. Since the cooking subassembly b is provided with the speed reducer 5, the torque of the sub-cutter k2 can be improved to meet the need of chopping food. Moreover, the sub-cutter k2 can be configured in multiple layers to cut more food at the same time. One device can realize two processing modes, saving cost.

[0045] Since the cooking subassembly b is detachably assembled with the cooking cavity 100, it is convenient to disassemble and clean. When stored, the cooking subassembly b can also be placed into the cooking cavity 100, occupying small space and being convenient to place. In addition, the configuration of the cooking subassembly b can process food separately. The food processed in the cooking subassembly b will not affect the cooking cavity 100. For example, raw meat is processed in the cooking subassembly b and is processed separately from the cooking assembly a, which is more hygienic and healthy.

[0046] Referring to Figure 5 and Figure 6 In an embodiment, the sub-cutter k1 is detachably connected with the output end 5.2 of the speed reducer. In this way, it is more convenient to clean. The sub-cutter k1 and the output end 5.2 of the speed reducer can be transmissionally coupled in the manner of a joint and a socket. For example, the sub-cutter k1 is provided with a protruding joint, the output end 5.2 of the speed reducer is provided with an interface, and a structure limiting relative rotation is arranged between the joint and the interface, such as a plum-blossom structure, a square structure, a flat structure, etc. It can also be other known structures of detachable connection of a cutter and a transmission output. Of course, it can also be a threaded connection structure.

[0047] Referring to Figure 2 , Figure 5 and Figure 6 In an embodiment, the upper end of the cutter k1 is provided with a transmission part k1.1, and the input end 5.1 of the speed reducer is coupled with the transmission part k1.1. In this way, the sub-cutter k2 can be directly coupled on the transmission part k1.1 without disassembling the cutter k1, which is convenient and fast to use.

[0048] In other embodiments, the cutter k1 is disassembled, and the input end 5.1 of the speed reducer is transmissionally coupled with the output end 3.1 of the driving mechanism 3. The transmission coupling manner can refer to the detachable connection manner of the sub-cutter k1 and the output end 5.2 of the speed reducer.

[0049] Referring to Figure 5 In an embodiment, the cover 2 is provided with a positioning structure rotationally matched with the upper end of the sub-cutter k2. In this way, the sub-cutter k2 can be kept stable during operation. The upper end of the sub-cutter k2 is positioned by the cover 2, which is simple in structure, convenient to use, and easy to clean.

[0050] Specifically, the cover 2 is configured with a first engaging portion 201 matched with the first upper end opening 10 of the cooking cavity 100, and a second engaging portion 202 matched with the upper end opening of the sub-cooking cavity 400. Through the above improvement, when the cover 2 is used to cover the upper end openings of the cooking cavity 100 and the sub-cooking cavity 400, the food materials can be prevented from being thrown out during the processing of the sub-cooking cavity 100.

[0051] In an embodiment, the first engaging portion 201 and the second engaging portion 202 can be made of soft material, such as silica gel or other materials known in the art. Since the size of the sub-cooking assembly b is smaller than that of the cooking cavity 100, the size of the sub-cooking cavity 400 is smaller than that of the cooking cavity 100, and therefore the size of the first engaging portion 201 (at least part of the sealing or engaging portion) is greater than that of the second engaging portion 202 (at least part of the sealing or engaging portion).

[0052] The first engaging portion 201 and the second engaging portion 202 can also be formed on one member, such as a flexible sleeve-shaped member, one or more first engaging pieces are formed on the outer surface of the sleeve-shaped member to form the first engaging portion, and one or more second engaging pieces are formed below the first engaging portion to form the second engaging portion. The size of the first engaging piece is greater than that of the first upper end opening 10 of the cooking cavity 100, and the size of the second engaging piece is greater than that of the upper end opening of the sub-cooking cavity 400. Since the first engaging portion and the second engaging portion are in the form of pieces, they have good elastic deformation, which can ensure that the cover 2 can be conveniently and easily covered on the upper end of the cooking cavity 100 and / or the upper end of the sub-cooking cavity 400. Of course, in general, the first engaging portion is tightly matched with the first upper end opening 10 of the cooking cavity 100 to ensure that the liquid food processed in the cooking cavity 100 will not splash out; the second engaging portion can also be tightly matched with the sub-cooking cavity 400.

[0053] In other embodiments, the first engaging portion and the second engaging portion can be two members, such as being made of flexible material respectively, and then being installed to the cover 2.

[0054] The positioning structure, as shown in Figure 5 The positioning structure, as shown in Figure 21 The positioning structure, as shown in

[0055] Referring to Figure 20In another embodiment, a sub-lid 2' is configured to open and close the second upper end opening 40 of the sub-cooking cavity 400, and the sub-lid 2' is provided with a positioning structure that is rotationally matched with the upper end of the sub-knife 2. The configuration of the sub-lid 2' can better adapt to the sub-cup assembly b, and after the sub-cup assembly b is taken out of the cooking cavity 100, the opening of the sub-cooking cavity 400 can be closed, playing a protective covering role, and also preventing the food in the sub-cooking cavity 400 from contacting the cooking cavity 100, playing a role in blocking hygiene, such as the sub-cooking cavity 400 being used for mincing meat, and the sub-lid 2' can prevent it from falling out into the cooking cavity 100.

[0056] As described above, the positioning structure can be a rotating shaft protrusion k2.1 arranged at the upper end of the sub-knife 2, and a rotating positioning hole is arranged on the sub-lid 2 to rotationally fit the rotating shaft protrusion k2.1. Of course, it can also be that Figure 21 as shown, the upper end of the sub-knife 2 is provided with a rotating positioning hole k2.1, and the sub-lid 2' is provided with a rotating shaft protrusion 2.1' matched with the rotating positioning hole k2.1.

[0057] In other embodiments (not shown), a sub-lid is configured to open and close the second upper end opening 40 of the sub-cup assembly 4, and the sub-lid is configured with a relief hole that avoids the upper end of the sub-knife 2. The upper end of the sub-knife 2 and the lid 2 are configured with a rotatingly matched positioning structure, which can adopt the structure in other embodiments of the present application.

[0058] Referring to Figures 1 to 8 In one embodiment, the cooking assembly a includes a cup assembly 1 and a first cup seat 1', and the driving mechanism 3 is installed on the first cup seat 1'.

[0059] As shown in the embodiment Figures 1 to 8 , a base c' is also configured, and the base c' is configured with a cavity c0' that positions the lower part of the cooking assembly a. The base c' is configured with a circuit module c.1' that is electrically coupled with the cooking assembly a. The base c' is also configured with a heat dissipation mechanism c.2. The specific structure of the base c' is not improved in the present application.

[0060] Referring to Figure 9 , the cooking assembly a only includes a cup assembly 1 and a cup seat area 1', and the driving mechanism 3 is installed on the cup seat area 1'.

[0061] In addition, in other embodiments, the cooking assembly a and the driving mechanism 3 can also be packaged in one overall shell.

[0062] Referring to Figures 10 to 15In an embodiment, the food processing subassembly b further comprises a subcup seat 6, the speed reducer 5 is arranged in the subcup seat 6, and the subcup body assembly 4 is connected to the upper side of the subcup seat 6. Arranging the speed reducer in the subcup seat 6 can make the food processing subassembly b compact in structure.

[0063] Referring to Figure 12 and Figure 14 In an embodiment, the subcup seat 6 comprises a subcup seat body 601 with a side wall 6011 and a top wall 6012, and a subcup seat cover 602 with a side wall 6021' and a bottom wall 6022', and the speed reducer 5 is mounted on the subcup seat cover 602. Specifically, the speed reducer 5 is mounted to a driving mounting portion 6022 of the subcup seat body 601, and the subcup seat cover 602 is connected to the inner side of the subcup seat body 601 through a connecting hole 6021, and the bottom wall 6022' is configured to avoid the input end 5.1 of the speed reducer 5.

[0064] Referring to Figures 13 to 15 In an embodiment, the subcup body assembly 4 is detachably connected to the subcup seat 6. With this scheme, the subcup body assembly b can be conveniently detached for cleaning.

[0065] Referring to Figures 13 to 15 In an embodiment, the subcup body assembly 4 comprises a subcup body 4.1 and a bottom wall 4.2, and a transmission hole 401 is configured in the middle of the bottom wall 4.2. The subcup body 4.1 and the bottom wall 4.2 can be manufactured by an integral molding process, such as injection molding of pc or pp materials, or can be manufactured by a glass forming process, or can be manufactured by a metal stamping or welding process.

[0066] Referring to Figures 13 to 15 In an embodiment, the bottom wall 4.2 extends upward from the edge of the transmission hole 401 to form a cylinder 402, the sub-knife k2 is provided with a fitting space k20 for sleeving the cylinder 402, and a sub-knife transmission joint k2.2 for at least indirectly coupling the driving mechanism 3 through the cylinder 402. Since the sub-knife k2 is detachable, the arrangement of the cylinder 402 can prevent residual materials or fluids from falling into the transmission hole 401 when the subcup body assembly 4 is detached, and can also prevent food materials from entering the transmission hole 401 during processing, thereby facilitating cleaning of the subcup body assembly 4.

[0067] Referring to Figure 10 , Figure 13 and Figure 14, the transmission hole 401 is downwardly extended to form a sealing wall, and the sealing part 4011 is formed on the inner side of the sealing wall.

[0068] In other embodiments, a transmission boss is arranged in the middle of the top wall 6012 of the sub-cup seat 6, the transmission hole lower part 4011 is arranged outside the transmission boss 60, and a sealing ring s is arranged between the transmission boss 60 and the transmission hole lower part 4011.

[0069] Referring to Figures 13 to 15 , one scheme for connecting the sub-cup body assembly 4 and the sub-cup seat 6 is a screwing structure 46, that is, the lower end of the sub-cup body assembly 4 is provided with a plurality of upper screwing parts 46.1, and the upper end 601 of the sub-cup seat 6 is provided with a plurality of lower screwing parts 46.2. When the upper screwing part 46.1 and the lower screwing part 46.2 are aligned, the two are fixedly connected, and when the sub-cup body assembly 4 and the sub-cup seat 6 are relatively rotated to disengage the upper screwing part 46.1 and the lower screwing part 46.2, the two are detachable.

[0070] In one embodiment, the upper screwing part 46.1 and the lower screwing part 46.2 are up-and-down staggered protrusions, as shown in Figures 13 to 15 , the upper screwing part 46.1 and the lower screwing part 46.2 are both protrusions, the lower side of the lower screwing part 46.2 forms a screwing-in side opening screwing-in channel 460, and the upper screwing part 46.1 is limited to the lower side of the lower screwing part 46.2 by screwing into the screwing-in channel 460. In order to facilitate the screwing-in of the upper screwing part 46.1 into the screwing-in channel 460, the screwing-in channel 460 is screwed into one side of the top wall and is provided with a beveled part.

[0071] In other embodiments, one of the screwing parts can be a rotating protrusion, and the other is provided with a clamping groove. The upper screwing part 46.1 and the lower screwing part 46.2 are connected and fixed by rotating to engage, and are disassembled by reversing the rotation. For example, the upper screwing part 46.1 is a rotating protrusion, and the lower screwing part 46.2 is a clamping groove. Figure 9 and Figure 10 As shown in

[0072] As shown in Figure 9 and Figure 10In the shown embodiment, the upper engaging rim 4.3 is sleeved with the outer side of the lower engaging rim 6.3, a plurality of the upper rotating connecting portions 46.1 are arranged at intervals on the inner side of the upper engaging rim 4.3, and a plurality of the lower rotating connecting portions 46.2 are arranged at intervals on the outer side of the lower engaging rim 6.3. When the upper engaging rim 4.3 is sleeved with the lower engaging rim 6.3, the upper rotating connecting portions 46.1 can be clamped into the lower side of the lower rotating connecting portions 46.2 by rotating, so as to fix the sub-cup body assembly 4 and the sub-cup seat 6. When the upper rotating connecting portions 46.1 are clamped out of the lower rotating connecting portions 46.2 by rotating, the sub-cup body assembly 4 can be disassembled from the sub-cup seat 6.

[0073] Specifically, the lower side of the lower rotating connecting portion 46.2 is configured with a clamping groove (rotating clamping channel 460) with the same rotating side opening. By such configuration, the sub-cup body assembly 4 can be connected with the sub-cup seat 6 only from one rotating direction, so as to ensure that the rotating connection is in place; when disassembling, the upper rotating connecting portion 46.1 is clamped out of the lower rotating connecting portion 46.2 by reversing the rotating direction.

[0074] Referring to Figure 15 , in order to ensure the reliability of the connection between the sub-cup body assembly 4 and the sub-cup seat 6, an anti-disassembly structure is arranged between the upper rotating connecting portion 46.1 and the lower rotating connecting portion 46.2. Specifically, one rotating connecting portion is configured with one or more protrusions 46.20, and the other rotating connecting portion is configured with one or more concave points 46.10. When the upper rotating connecting portion 46.1 is connected with the lower rotating connecting portion 46.2, the protrusions 46.20 and the concave points 46.10 are engaged. When installing and disassembling, the user needs to exert a certain rotating torque to make the sub-cup body assembly 4 and the sub-cup seat 6 assembled or disassembled, so as to ensure that the sub-cup body assembly 4 and the sub-cup seat 6 are not loosened during use. For example, the concave points 46.10 are configured on the upper rotating connecting portion 46.1, and the protrusions 46.20 are configured on the inner wall of the rotating clamping channel 460. When the upper rotating connecting portion 46.1 is rotated into the rotating clamping channel 460 to be in place, the concave points 46.10 are clamped into the protrusions 46.20, which can effectively prevent the sub-cup body assembly 4 and the sub-cup seat 6 from being loosened after being connected.

[0075] As shown in Figure 15 , the protrusions 46.10 are arranged on the inner wall of the end of the lower rotating connecting portion 46.2 (clamping groove), and the concave points 46.10 are arranged on the outer edge of the upper rotating connecting portion 46.1. Of course, the protrusions 46.20 and the concave points 46.10 are not limited to the above positions, and can be arranged at other positions of the lower rotating connecting portion 46.2 and the upper rotating connecting portion 46.1 according to needs.

[0076] In other embodiments, the engaging rim 4.3 can also be designed to be sleeved with the inner side of the lower engaging rim 6.3. At this time, the upper rotating connecting portion 46.1 is arranged on the outer side of the upper engaging rim 4.3, and the lower rotating connecting portion 46.2 is arranged on the inner side of the lower engaging rim 6.3.

[0077] In other embodiments, the upper rotating connecting portion 46.1 is a clamping groove.

[0078] In other embodiments, the sub-cup assembly 4 and the sub-cup seat 6 are connected by a threaded structure.

[0079] See Figure 10 and Figure 18 The inner wall of the sub-cup body 4.1 of this application has one or more flow-dispersing ribs b01'. The flow-dispersing ribs b01' are preferably vertically extending and spaced apart. (See attached...) Figure 10 In the illustrated embodiment, the baffle rib b01' is formed by protruding inward from the side wall of the sub-cup body 4.1. Specifically, when the sub-cup body 4.1 is made of plastic or glass, the baffle rib b01' is integrally manufactured with the sub-cup body 4.1; when the sub-cup body 4.1 is made of metal, the baffle rib b01' is formed by stamping. To facilitate observation of the processing status of the sub-cup cavity 400, the sub-cup body 4.1 is preferably made of a transparent material, such as transparent plastic or glass; it is readily understood that these materials are well-known.

[0080] See Figures 16 to 19 In another embodiment of the cooking sub-assembly b of this application, the cooking sub-assembly b includes a sub-cup body assembly 4 and a sub-cup seat 6. The sub-cup body assembly 4 includes a sub-cup body 4.1 and a base 4.2. The sub-cup body 4.1 has an upper port and a lower port. The base 4.2 is sealed to the lower end of the sub-cup body 4.1 by a sealing ring s'. The sub-cup seat 6 is connected to the lower side of the base 4.2. The deceleration device 5 is disposed in the sub-cup seat 6. As can be seen from the foregoing, disposing of the deceleration device 5 in the sub-cup seat 6 can make the cooking sub-assembly b have a compact structure.

[0081] See Figure 12 , Figure 14 , Figures 16 to 19 In one embodiment, the sub-cup holder 6 includes a sub-cup holder body 601 having side walls 6011 and a top wall 6012, and a sub-cup holder cover 602 having side walls 621' and a bottom wall 6022'. The deceleration device 5 is installed on the sub-cup holder cover 602. Specifically, the deceleration device 5 is installed on the drive mounting part 6022 of the sub-cup holder body 601. The sub-cup holder cover 602 is connected to the inside of the sub-cup holder body 601 through a connecting hole 6021. The bottom wall 6022' is configured to avoid the input end 5.1 of the deceleration device 5.

[0082] For a specific connection method between the sub-cup holder 6 and the sub-cup body assembly 4, see [link to relevant documentation]. Figures 16 to 19The lower end of the sub-cup body 4.1 is configured with an inwardly extending lower connecting portion 4.10, the sealing ring s' is configured with a sealing assembly groove in communication with the outside, the sealing ring s' is sleeved on the lower connecting portion 4.10 through the sealing assembly groove, the edge of the bottom disc 4.2 extends to the lower connecting portion 4.10 to cover the upper side of the sub-sealing ring s', and the sub-cup seat 6 is connected to the bottom disc 4.2 through a connecting piece such as a screw to tension the bottom disc 4.2, so that the bottom disc 4.2 and the connecting portion 4.10 extrude the sealing ring s' to achieve sealing.

[0083] Specifically, the top wall 6012 of the sub-cup seat 6 is configured with a connecting hole 60120, and the screw is directly or indirectly (such as by configuring other intermediate connecting pieces) connected with the bottom disc 4.2 through the connecting hole 60120.

[0084] In addition to the screw connection described above, the sub-cup body 4.1 and the sub-cup seat 6 can also be made of engineering plastics and connected by ultrasonic welding, known adhesive materials, etc.

[0085] The bottom disc 4.2 is made of a material with high structural strength, such as metal (stainless steel, aluminum alloy, etc.), and can also be a known plastic material that meets the structural strength.

[0086] A plurality of positioning protrusions b012' are configured on the edge of the top wall 6012 of the sub-cup seat 6, and the outer wall of the sub-cup body 4.1 is recessed to form a groove structure b011' in communication with its lower end at a position corresponding to the one or more turbulence ribs b01', and the positioning protrusions b012' are embedded in the groove structure b011'. Through the above structure, the circumferential stress of the sub-cup body assembly 4 and the sub-cup seat 6 can be applied between the positioning protrusions b012' and the groove structure b011', thereby reducing the stress on the vertical connection (such as screw connection) of the sub-cup body assembly 4 and the sub-cup seat 6, and making the structure more stable and reliable.

[0087] As known from the foregoing description, when the sub-cup body 4.1 is made of plastic or glass material, the turbulence rib b01' is integrally formed with the sub-cup body 4.1; when the sub-cup body 4.1 is made of metal material, the turbulence rib b01' is formed by stamping.

[0088] Referring to Figure 2 and Figure 11In an embodiment, the inner wall of the cooking cavity 100 is provided with a plurality of vertically spaced positioning protrusions a01, and the side of the cooking subassembly b is provided with a plurality of spaced positioning grooves b01. When the cooking subassembly b is installed into the cooking cavity 100, the positioning protrusions a01 are inserted into the positioning grooves b01 to limit the rotation of the cooking subassembly b. With the above scheme, the rotation of the cooking subassembly b caused by the reaction force of food during operation can be limited. Moreover, the structure is simple and convenient to assemble. The positioning protrusions a01 also have the function of disturbing flow, which makes the food processing effect better. Therefore, in some embodiments, the positioning protrusions a01 can directly use the original disturbing ribs of the inner wall of the cooking cavity 100, without the need for additional design and processing, thereby reducing production cost.

[0089] In some embodiments, the positioning grooves b01 are at least configured on one of the sub-cup body assembly 4 and the sub-cup seat 6. In a specific preferred embodiment, as shown in Figure 3 、 Figure 11 、 Figure 12 、 Figure 15 、 Figure 16 and Figure 19 , the positioning grooves b01 are preferably configured on the sub-cup body assembly 4 and the sub-cup seat 6, i.e., the positioning grooves b01 on the respective parts of the sub-cup body assembly 4 and the sub-cup seat 6 correspond to each other in up and down directions and are connected to the lower end of the sub-cup seat 6. With this structure, the cooking subassembly b can be conveniently installed into the cooking cavity 100 from top to bottom, and the positioning grooves b01 and the positioning protrusions a01 are matched.

[0090] In the embodiments shown in Figure 3 、 Figure 11 、 Figure 12 、 Figure 15 、 Figure 16 and Figure 19 , the positioning protrusions a01 are located in the positioning grooves b01 of the sub-cup body assembly 4 and the sub-cup seat 6 at the same time. With this structure, the circumferential force received by the cooking subassembly b can be simultaneously transmitted from the sub-cup body assembly 4 and the sub-cup seat 6 to the positioning protrusions a01, which optimizes the force received by the cooking subassembly b and avoids that one of the sub-cup body assembly 4 and the sub-cup seat 6 is damaged due to excessive force.

[0091] Of course, in other embodiments, the positioning grooves b01 are only configured on the sub-cup body assembly 4, and in this case, the corresponding avoiding structure needs to be provided on the sub-cup seat 6, such as a recess or avoiding plane designed at the part of the sub-cup seat 6 corresponding to the positioning grooves b01, or the side size of the sub-cup seat 6 is directly designed to be smaller than the inner side of the positioning grooves b01.

[0092] In other embodiments, the positioning grooves b01 are only configured on the sub-cup seat 6.

[0093] The design of the two positioning grooves b01 can meet the positioning requirements by optimizing the structure of the sub-cup assembly 4 or the sub-cup seat 6, such as material selection, thickness selection, and adding reinforcing structures.

[0094] As Figure 3 , Figure 11 , Figure 12 , Figure 15 , Figure 16 and Figure 19 In the embodiments shown in

[0095] Referring to Figure 5 , Figure 11 and Figure 12 In an embodiment, the lower end of the cooking sub-assembly b is provided with one or more support portions b02, and the cooking sub-assembly b is installed above the bottom wall of the cooking cavity 100 through the one or more support portions b02. With the above scheme, the cooking sub-assembly b can be stably supported. With the above scheme, during operation, the buffer can reduce the vibration between the cooking assembly and the cooking cavity, and also play a role in noise reduction. Referring to Figure 5 , Figure 11 and Figure 12 In the embodiments shown in

[0096] As shown in Figure 5 , Figures 11 to 14 An avoidance space b0 is formed between the inner side of the support portion b02 and the bottom of the sub-cup seat 6. When the cooking sub-assembly b is installed into the cooking cavity 100 and the input end 5.1 of the speed reducer 5 is coupled with the transmission portion k1.1 of the cutter k1, the avoidance space b0 can avoid the cutter k1.

[0097] When multiple support portions b02 are used, the adjacent support portions b02 form an exhaust channel b03, which can exhaust the airflow generated during the operation of the cutter k1 and the wind pressure parallel to the bottom of the cooking sub-assembly b.

[0098] Of course, the exhaust channel b03 can also be in other forms, such as the bottom of the sub-cup seat 6 being provided with an avoidance space b0, the lower end of the wall of the sub-cup seat 6 serving as a support portion, and the lower end of the sub-cup seat 6 being provided with an exhaust channel b03 communicating with the avoidance space b0, such as a hole structure or a groove structure.

[0099] Referring to Figure 11 and Figure 12In an embodiment, the one or more support portions b02 are provided with a buffer b.1 in contact with the bottom wall of the cooking cavity 100.

The buffer b.1 is preferably flexible, such as a silicone material, and can also be other known flexible materials. The buffer b.1 can reduce the impact with the bottom wall of the cooking cavity 100, prevent or reduce the generation of noise; on the other hand, when the cooking subassembly b is taken out and placed in another position (such as a countertop), the buffer b.1 serves as an anti-slip function.

[0100] In some embodiments, in order to facilitate the taking and placing of the cooking subassembly b, a handle (not shown) that can be turned over for storage is provided on the upper end side of the cooking subassembly b.

[0101] Referring to Figures 11 to 15 , the technical solutions of the cooking subassembly b are described as follows: the cooking subassembly b comprises: a sub-cup assembly 4 having a second upper end opening 40; a sub-knife k2 provided in the sub-cooking cavity 400; a speed reduction device 5 provided on the lower side of the sub-cup assembly 4, comprising a speed reduction mechanism 50, and an input end 5.1 of the speed reduction device 5 and a speed reduction device output end 5.2, wherein the sub-knife k1 is drivingly coupled to the speed reduction device output end 5.2.

In other embodiments, a step can also be arranged on the side wall of the cooking cavity 100, and the outer side of the cooking sub-assembly b is provided with a structure matched with the step to achieve the installation of the cooking sub-assembly b to the cooking cavity 100, such as arranging a step on the upper part of the step of the cooking cavity 100, and arranging a protrusion on the outer side of the upper part of the cooking sub-assembly b. The protrusion of the cooking sub-assembly b is installed on the step to make the cooking sub-assembly b hang on the cooking cavity 100 as a whole.

The buffer b.1 is preferably flexible, such as a silicone material, and can also be other known flexible materials. The buffer b.1 can reduce the collision with the base c, prevent or reduce the generation of noise; on the other hand, when the sub-cooking assembly b is taken out and placed on other positions (such as the table top), the buffer b.1 plays a role in preventing slipping.

[0121] The food can be processed by the cooking assembly a, and when the food needs to be chopped into larger particles or non-fluid processing, the cooking assembly a is taken off the base c, and the sub-cooking assembly b is assembled to the connecting table c01. Since the sub-cooking assembly b is provided with a speed reducer 5, the torque of the sub-cutter k2 can be improved to meet the need of chopping food, and the sub-cutter k2 can be provided with multiple layers to cut more food at the same time. One device can realize two processing modes, saving cost. When stored, the sub-cooking assembly b can be placed in the cooking cavity 100, occupying a small space and being convenient to place.
