[0003] The utility model belongs to the technical field of food cooking appliances, and in particular relates to a food chopper, in particular to a food chopper realized by configuring a cooking subassembly. Background Art

[0004] A food processor is an appliance that uses a motor-driven, high-speed rotating blade to chop ingredients. Because the blades in a food processor are relatively low, a fluid, such as water, is usually added to aid in stirring and chopping the ingredients. Therefore, food processors are generally not suitable for non-fluid chopping, such as mincing meat, cutting condiments, and stuffings into a specific size. This is because the blades are relatively low, rotate quickly, and cannot be supplemented with fluids, effectively chopping only the food at the bottom. Furthermore, non-fluid chopping in a food processor is difficult to clean, which can easily lead to odors and hygiene issues. Therefore, people need to purchase a dedicated chopper for non-fluid chopping operations such as mincing meat, cutting condiments, and stuffings.

[0005] For the above reasons, people need to purchase multiple devices, which is costly and takes up a lot of space. Summary of the Invention

[0006] The purpose of the present invention is to solve the problem in the prior art that multiple devices need to be purchased for food cooking and non-fluid chopped food processing, which is costly and takes up a lot of space. By designing a cooking sub-assembly, the cooking sub-assembly can be selectively installed in the cooking chamber and coupled with the drive mechanism to achieve the problem of chopping the food into larger particles.

[0007] This application adopts a technical solution as follows:

[0008] The food chopper comprises a cooking assembly, a cooking sub-assembly and a positioning mechanism. The cooking assembly comprises a cup assembly having a cooking cavity with an upper end opening, a driving mechanism arranged at the lower side of the cup assembly, and a cutter arranged at the bottom of the cooking cavity and drivingly coupled with the driving mechanism. The cooking sub-assembly is detachably assembled in the cooking cavity and comprises a sub-cup assembly having a sub-cooking cavity with an upper end opening, a sub-cup seat arranged at the lower side of the sub-cup assembly and provided with one or more supporting portions at the lower end, a speed reducer arranged in the sub-cup seat and having a sub-cutter driving input end and a sub-cutter driving output end, and a sub-cutter arranged in the sub-cooking cavity and detachably coupled with the sub-cutter driving output end. The positioning mechanism comprises a plurality of vertically extending and spaced positioning protrusions arranged on the inner wall of the cooking cavity and a plurality of vertically extending and spaced positioning grooves arranged on the outer side of the cooking sub-assembly. The cooking sub-assembly is supported on the bottom wall of the cooking cavity by the one or more supporting portions, the positioning protrusions are inserted into the positioning grooves to limit the rotation of the cooking sub-assembly, and the sub-cutter driving input end is at least indirectly detachably drivingly coupled with the driving mechanism.

[0009] The food chopper of the present application can perform food cooking processing through the cooking assembly. For food processing or non-fluid processing that needs to be chopped into a specific degree of fineness, the cooking sub-assembly is assembled into the cooking cavity, and the sub-cutter driving input end is drivingly coupled with the driving mechanism. Since the sub-cutter is arranged flexibly and can be arranged in multiple layers, more food can be cut at the same time. Thus, the two processing modes can be realized by one device, saving cost. Since the cooking sub-assembly is detachably assembled with the cooking cavity, it is convenient to disassemble and clean. Through the positioning mechanism, it can be ensured that the cooking sub-assembly does not rotate during work, and the cooking sub-assembly can be placed in the cooking cavity during storage, occupying small space and being convenient to place.

[0010] Further, the positioning grooves are formed on the sub-cup assembly and / or the sub-cup seat.

[0011] Further, the positioning protrusions are turbulence fins formed on the inner wall of the cooking cavity. This scheme can directly use the original turbulence fins of the cooking cavity for positioning, which is simple in structure and low in cost.

[0012] Further, the positioning grooves are v-shaped, which is convenient for users to assemble and disassemble.

[0013] Further, the upper end of the cutter is provided with a driving protrusion, and the sub-cutter driving input end is coupled with the driving protrusion. This scheme can couple the sub-cutter driving input end with the driving protrusion without disassembling the cutter, which is convenient and fast to use.

[0014] As an alternative, the sub-cutter driving input end is drivingly coupled with the output end of the driving mechanism after the cutter is disassembled.

[0015] Further, the lower end side of the sub-cup seat is provided with one or more support portions, and the food processing sub-assembly is supported on the bottom wall of the food processing cavity through the one or more support portions. In addition, after the food processing sub-assembly is taken out of the food processing cavity, it can be placed on a flat surface through the support portions, which is convenient to use.

[0016] The one or more support portions are provided with a buffer in contact with the bottom wall of the food processing cavity. In operation, the buffer can reduce the vibration between the food processing assembly and the food processing cavity, and also play a role in noise reduction. After being taken out of the food processing cavity, it is more stable when placed on a flat surface through the buffer.

[0017] Further, the cover covers the upper end opening of the sub-cup body assembly, and the cover is provided with a positioning structure in rotational cooperation with the upper end of the sub-knife. In this way, the sub-knife can be kept stable during operation.

[0018] The technical effects of the present application are more embodied in the embodiments. BRIEF DESCRIPTION OF DRAWINGS

[0043] Referring to Figures 1 to 4The utility model relates to food chopper and cooking subassembly b as a whole, the detachable coupling of the utility model, for the detachable connection of realizing rotary transmission, such as the input end 5.1 of the speed reducer of speed reducer 50 is used for detachable transmission coupling with the driving mechanism 3, namely the detachable and circumferential position of speed reducer input end 5.1 and the output end 3.1 of driving mechanism 3 have ground connection, such as square shaft and square hole, or polygonal shaft and polygonal hole, or the cooperation of keyhole and shaft, or the transmission cooperation structure of prior art in the field. Transmission coupling can be detachable coupling, or fixed connection.

[0044] The sub cutter k2 is the cutter that can realize mincing food materials into larger granularity, generally needs to configure multilayer blade, such as more than two layers, of course, the number of blade can be set according to actual, and in some embodiments, it can also be one layer. In addition, regarding the use of cooking subassembly b, the protection scope of the present application is not limited to mincing, and can also be other uses that need to be processed separately from cooking assembly a. As shown, Figure 10 The sub cutter k2 includes the cutter body k2' and the blade k2.1' arranged on the cutter body k2', and the blade k2.1' is arranged on the cutter body k2'. Figure 10 An embodiment provided with two layers of blades k2.1' is shown, and in other embodiments, one layer or three layers or more can be arranged. Regarding the assembly of the blade k2.1' and the cutter body k2', the cutter body k2' can be injection molded in parts and then assembled with the blade k2.1', such as interference fit, threaded connection, and the like commonly used in the art, or the blade k2.1' and the cutter body k2' can be injection molded and fixed. Of course, related structures in the chopper, such as a meat grinder, can also be used to achieve the above.

[0045] Referring to Figures 1 to 8 In some embodiments, the food chopper includes: a cooking assembly a and a cooking subassembly b; the cooking assembly a includes: a cup assembly 1, a cooking cavity 100 with a first upper end opening 10; a cover 2 for opening and closing the first upper end opening 10 of the cooking cavity 100; a driving mechanism 3 arranged on the lower side of the first cup assembly 1, including a driving motor; a cutter k1 arranged at the bottom of the cooking cavity 100 and transmission coupled with the driving mechanism 3; the cooking subassembly b is detachably assembled in the cooking cavity 100 and includes: a sub-cup assembly 4, a sub-cooking cavity 400 with a second upper end opening 40; a sub-cutter k2 arranged in the sub-cooking cavity 400; a speed reducer 5 arranged on the lower side of the sub-cup assembly 4, including a speed reducer mechanism 50, a speed reducer input end 5.1 and a speed reducer output end 5.2, the speed reducer input end 5.1 is used for detachable transmission coupling with the driving mechanism 3, and the sub-cutter k1 is transmission coupled with the speed reducer output end 5.2.

[0046] The speed reduction mechanism 50 of the present application can be a gear train speed reduction mechanism, such as speed reduction through one or more sets of gears with different transmission ratios, which can include a combination of double gears and single gears, or a combination of multiple double gears, or a combination of multiple single gears; or speed reduction through a planetary speed reduction mechanism. Such speed reduction mechanisms can be implemented according to now known speed reduction mechanisms.

[0047] 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 reduction device is transmissionally coupled with the driving mechanism 3. Since the cooking subassembly b is provided with the speed reduction device 5, the torque of the sub-knife k2 can be improved to meet the need for chopping food. Moreover, the sub-knife k2 can be configured in multiple layers to simultaneously cut more food. One device can realize two processing modes, saving cost.

[0048] Since the cooking subassembly b and the cooking cavity 100 are detachably assembled, they are 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, such as raw meat processed in the cooking subassembly b and separated from the cooking assembly a, which is more hygienic and healthy.

[0049] Referring to Figure 5 and Figure 6 In an embodiment, the sub-knife k1 is detachably connected with the output end 5.2 of the speed reduction device. In this way, it is more convenient to clean. The sub-knife k1 and the output end 5.2 of the speed reduction device can be transmissionally coupled in a joint and socket manner, such as the sub-knife k1 being provided with a protruding joint and the output end 5.2 of the speed reduction device being provided with an interface, and a structure limiting relative rotation being arranged between the joint and the interface, such as a plum blossom structure, a square structure, a flat bit structure, etc. It can also be other known structures of detachable connection of a knife and a transmission output. Of course, it can also be a threaded connection structure.

[0050] Referring to Figure 2 , Figure 5 and Figure 6 In an embodiment, the upper end of the knife k1 is provided with a transmission part k1.1, and the input end 5.2 of the speed reduction device is coupled with the transmission part k1.1. In this way, the sub-knife k2 can be directly coupled on the transmission part k1.1 without the need to disassemble the knife k1, which is convenient and fast to use.

[0051] In other embodiments, the tool is replaced, that is, the tool k1 is disassembled, and the input end 5.2 of the speed reducer is coupled with the output end 3.1 of the driving mechanism 3. The coupling manner can refer to the detachable connection manner of the sub-tool k1 and the output end 5.2 of the speed reducer.

[0052] Referring to Figure 5 In an embodiment, the cover 2 is provided with a positioning structure that is rotationally matched with the upper end of the sub-tool k2. In this way, the sub-tool k2 can be kept stable during operation. The upper end of the sub-tool k2 is positioned by the cover 2, which is simple in structure, convenient to use, and easy to clean.

[0053] Specifically, the cover 2 is provided with a first engaging part 201 that is matched with the first upper end opening 10 of the cooking cavity 100, and a second engaging part 202 that is 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 opening of the cooking cavity 100 and the upper end opening of the sub-cooking cavity 400, the food material can be prevented from being thrown out during processing in the sub-cooking cavity 100.

[0054] In an embodiment, the first engaging part 201 and the second engaging part 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 part 201 is at least partially (sealing or engaging part) larger than that of the second engaging part 202 (sealing or engaging part).

[0055] The first engaging part 201 and the second engaging part 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 part, and one or more second engaging pieces are formed below the first engaging part to form the second engaging part. The size of the first engaging piece is larger than that of the first upper end opening 10 of the cooking cavity 100, and the size of the second engaging piece is larger than that of the upper end opening of the sub-cooking cavity 400. Since the first engaging part and the second engaging part 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, generally, the first engaging part is closely 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 part can also be closely matched with the sub-cooking cavity 400.

[0056] In other embodiments, the first engaging part and the second engaging part can be two members, such as being made of flexible material and then being installed to the cover 2.

[0057] The positioning structure can be, for example Figure 5As shown, a rotating shaft protrusion k2.1 is configured on the upper end of the sub-knife k2, and a rotating positioning hole 2.1 is configured on the cover 2, and the rotating shaft protrusion k2.1 is rotatably assembled into the rotating positioning hole 2.1. Of course, the rotating shaft protrusion k2.1 and the rotating positioning hole 2.1 can be interchanged, such as Figure 21 As shown, a rotating shaft protrusion is configured on the cover 2, and a rotating positioning hole 2.1 is configured on the upper end of the sub-knife k2.

[0058] Referring to Figure 20 In another embodiment, a sub-cover 2' is configured, which is used to open and close the second upper end opening 40 of the sub-cooking cavity 400, and the sub-cover 2' is provided with a positioning structure that is in rotational cooperation with the upper end of the sub-knife k2. The configuration of the sub-cover 2' can better adapt to the sub-cup assembly b, and after the sub-cup assembly b is taken out from the cooking cavity 100, the opening of the sub-cooking cavity 400 can be closed, thereby playing a protective covering role, and also preventing the food in the sub-cooking cavity 400 from contacting the cooking cavity 100, thereby playing a role in blocking hygiene, such as when the sub-cooking cavity 400 is used for mincing meat, the sub-cover 2' can prevent the minced meat from falling out into the cooking cavity 100.

[0059] As described above, the positioning structure can be a rotating shaft protrusion k2.1 configured on the upper end of the sub-knife k2, and a rotating positioning hole 2.1 configured on the cover 2 that cooperates with the shaft protrusion k2.1, and the rotating shaft protrusion k2.1 is rotatably assembled into the rotating positioning hole. Of course, it can also be as shown Figure 21 As shown, a rotating shaft protrusion k2.1 is configured on the upper end of the sub-knife k2, and a rotating positioning hole 2.1 is configured on the cover 2 that cooperates with the shaft protrusion k2.1, and the rotating shaft protrusion k2.1 is rotatably assembled into the rotating positioning hole. Of course, it can also be as shown

[0060] In other embodiments (not shown), a sub-cover is configured, which is used to open and close the second upper end opening 40 of the sub-cooking cavity 400, and the sub-cover is configured with a avoiding hole that avoids the upper end of the sub-knife k2, and the upper end of the sub-knife k2 and the cover 2 are configured with a positioning structure that is in rotational cooperation, and the positioning structure can adopt the structure in other embodiments of the present application.

[0061] 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 mounted on the first cup seat 1'.

[0062] As Figures 1 to 8 In the embodiment as shown, a base c' is also configured, which is configured with a cavity c0' that positions the lower part of the cooking assembly a, and the base c' is configured with a circuit module c.1' that is electrically coupled with the cooking assembly a, and the base c' is also configured with a heat dissipation mechanism c.2. The specific structure of the base c' is not the improvement of the present application.

[0063] Referring to Figure 9As shown, the cooking assembly a only includes the cup assembly 1 and the cup seat area 1', and the driving mechanism 3 is installed in the cup seat area 1'.

[0064] In addition, in other embodiments, the cooking assembly a and the driving mechanism 3 can be packaged in a whole shell.

[0065] Referring to Figures 10 to 15 In an embodiment, the cooking sub-assembly b further includes a sub-cup seat 6, the speed reducer 5 is arranged in the sub-cup seat 6, and the sub-cup assembly 4 is connected to the upper side of the sub-cup seat 6. Arranging the speed reducer in the sub-cup seat 6 can make the cooking sub-assembly b compact in structure.

[0066] Referring to Figure 12 and Figure 14 In an embodiment, the sub-cup seat 6 includes a sub-cup seat body 601 with a side wall 6011 and a top wall 6012, and a sub-cup seat cover 602 with a side wall 6.21' and a bottom wall 6022'. The speed reducer 5 is installed in the sub-cup seat cover 602. Specifically, the speed reducer 5 is installed to the driving installation part 6022 of the sub-cup seat body 601, the sub-cup seat cover 602 is connected to the inner side of the sub-cup seat body 601 through the connecting hole 6021, and the bottom wall 6022' is configured to avoid the speed reducer input end 5.1.

[0067] Referring to Figures 13 to 15 In an embodiment, the sub-cup assembly 4 is detachably connected to the sub-cup seat 6. With this scheme, the sub-cup assembly b can be easily detached for cleaning.

[0068] Referring to Figures 13 to 15 In an embodiment, the sub-cup assembly 4 includes a sub-cup 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 sub-cup 4.1 and the bottom wall 4.2 can be manufactured by integral molding process, such as pc, pp material injection molding integral molding; or by glass forming; or by hardware material stamping, welding and other current processes.

[0069] 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 configuration of the cylinder 402 can prevent residual material or fluid from falling into the transmission hole 401 when the sub-cup assembly 4 is detached; and also prevent food materials from entering the transmission hole 401 during processing, thereby facilitating cleaning of the sub-cup assembly 4.

[0070] Referring to Figure 10 ,Figure 13 And Figure 14 , the transmission hole 401 is configured with a sealing part 4011 with increased diameter at the lower part, the top wall 6012 of the boss body 601 of the output end 5.2 of the speed reducer, and a sealing ring s between the output end 5.2 of the speed reducer and the sealing part 4011. With the above scheme, the transmission hole 401 and the sealing part 4011 can be effectively sealed. In order to facilitate production and manufacturing, the transmission hole 401 extends downward to form a sealing wall, and the sealing part 4011 is formed on the inner side of the sealing wall.

[0071] In other embodiments, a transmission boss is arranged in the middle of the top wall 6012 of the sub-boss 6, the output end 5.2 of the speed reducer is arranged in the transmission boss, and the transmission hole lower part 4011 is arranged outside the transmission boss 60. The transmission boss 60 and the transmission hole lower part 4011 are arranged with a sealing member s.

[0072] Referring to Figures 13 to 15 , one scheme for connecting the sub-cup assembly 4 and the sub-boss 6 is a screw joint structure 46, that is, the lower end of the sub-cup assembly 4 is provided with a plurality of upper screw joint parts 46.1, and the upper end 601 of the sub-boss 6 is provided with a plurality of lower screw joint parts 46.2. When the upper screw joint part 46.1 and the lower screw joint part 46.1 are aligned, the two are fixedly connected, and when the upper screw joint part 46.1 and the lower screw joint part 46.1 are disengaged by rotating the sub-cup assembly 4 and the sub-boss 6 relative to each other, the two can be disassembled.

[0073] In one embodiment, the upper screw joint part 46.1 and the lower screw joint part 46.1 are upper and lower staggered protrusions, as shown in Figures 13 to 15 , the upper screw joint part 46.1 and the lower screw joint part 46.1 are both protrusions, the lower side of the lower screw joint part 46.1 forms a screw-in side opening screw-in channel 460, and the upper screw joint part 46.1 is limited to the lower side of the lower screw joint part 46.1 by screwing into the screw-in channel 460. In order to facilitate the screwing of the upper screw joint part 46.1 into the screw-in channel 460, the screw-in channel 460 is screwed into one side of the top wall and is provided with a beveled part.

[0074] In other embodiments, one of the screw joint parts can be a rotating protrusion, and the other can be a clamping groove. By rotating, the upper screw joint part 46.1 and the lower screw joint part 46.1 are engaged to achieve connection and fixation, and by reversing the rotation, disassembly is achieved. For example, the upper screw joint part 46.1 is a rotating protrusion, and the lower screw joint part 46.2 is a clamping groove. Figure 9 And Figure 10 , the upper end of the sub-boss 6 is provided with a lower joint edge 6.3, and the lower end of the sub-cup assembly 4 is provided with an upper joint edge 4.3. The lower joint edge 6.3 and the upper joint edge 4.3 are respectively provided with the upper screw joint part 46.1 and the lower screw joint part 46.2 on the side of mutual fitting.

[0075] For example,Figure 9 And Figure 10 In one embodiment as shown in FIG. 4, 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.

[0076] 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 and the lower rotating connecting portion 46.2 are clamped out by reverse rotating, and the sub-cup body assembly 4 can be disassembled from the sub-cup seat 6.

[0077] Referring to FIG. 4, Figure 15 In order to ensure the reliability of the connection between the sub-cup body assembly 4 and the sub-cup seat 6, a disengaging 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 and the lower rotating connecting portion 46.2 are connected, 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 in place, 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 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.

Specifically, when the sub-cup 4.1 is made of plastic or glass, the spoiler ribs b01' are integrally formed with the sub-cup 4.1. When the sub-cup 4.1 is made of metal, the spoiler ribs b01' are stamped. To facilitate observation of the processing status of the sub-cup 400, the sub-cup 4.1 is preferably made of a transparent material, such as transparent plastic or glass. As will be appreciated, these materials are well known.

[0083] See also Figures 16 to 19 Another embodiment of the cooking subassembly B of the present application comprises a sub-cup assembly 4 and a sub-cup holder 6. The sub-cup assembly 4 comprises a sub-cup 4.1 and a base 4.2. The sub-cup 4.1 has an upper port and a lower port. The base 4.2 is sealed to the lower end of the sub-cup 4.1 via a sealing ring 4.3. The sub-cup holder 6 is connected to the lower side of the base 4.2, and the reduction gear 5 is disposed within the sub-cup holder 6. As previously mentioned, disposing the reduction gear 5 within the sub-cup holder 6 makes the cooking subassembly B more compact.

[0084] See also Figure 12 、 Figure 14 、 Figures 16 to 19 In one embodiment, the sub-cup holder 6 includes a sub-cup holder body 601 having a side wall 6011 and a top wall 6012, and a sub-cup holder cover 602 having a side wall 6.21' and a bottom wall 6022'. The reduction gear 5 is mounted on the sub-cup holder cover 602. Specifically, the reduction gear 5 is mounted to the drive mounting portion 6022 of the sub-cup holder body 601. The sub-cup holder cover 602 is connected to the inner side of the sub-cup holder body 601 through a connecting hole 6021. The bottom wall 6022' is configured to avoid the reduction gear input end 5.1.

[0085] A specific connection method between the sub-cup seat 6 and the sub-cup body assembly 4 is shown in FIG. 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 4.3 is configured with a sealing assembly groove in communication with the outside, the sealing ring 4.3 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 sealing ring 4.3, and the sub-cup seat 6 is connected to the bottom disc 4.2 through a connecting member such as a screw to pull the bottom disc 4.2 tightly, so that the bottom disc 4.2 and the connecting portion 4.10 extrude the sealing ring 4.3 to achieve sealing.

[0086] 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 members) connected to the bottom disc 4.2 through the connecting hole 60120.

[0087] 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, commonly known adhesive materials, etc.

[0088] 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 commonly known plastic material that meets the structural strength.

[0089] A plurality of positioning protrusions b012' are configured on the edge of the top wall 6012 of the sub-cup seat 6, and a groove structure b011' in communication with the lower end is formed in the position corresponding to the one or more turbulence ribs b01' on the outer wall of the sub-cup body 4.1, 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.

[0090] 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.

[0091] Referring to Figure 2 and Figure 11 , Figure 22 and Figure 23In 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, thereby limiting the rotation of the cooking subassembly b. With the above arrangement, the rotation of the cooking subassembly b caused by the reaction force of the 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 the flow, so that the food processing effect is 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 the production cost.

[0092] In some embodiments, the positioning grooves b01 are arranged on at least 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 arranged on the sub-cup body assembly 4 and the sub-cup seat 6, i.e., the positioning grooves b01 on the sub-cup body assembly 4 and the sub-cup seat 6 are arranged in a corresponding and communicating manner from top to bottom 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 can be matched.

[0093] 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, thereby optimizing the force received by the cooking subassembly b and avoiding that one of the sub-cup body assembly 4 and the sub-cup seat 6 is damaged due to excessive force.

[0094] In some embodiments, the positioning grooves b01 are v-shaped, which facilitates assembly and disassembly.

[0095] Of course, in other embodiments, the positioning grooves b01 are arranged only on the sub-cup body assembly 4, in which case corresponding avoiding structures need to be arranged on the sub-cup seat 6, such as recesses or avoiding planes designed at the positions of the sub-cup seat 6 corresponding to the positioning grooves b01, or the side dimension of the sub-cup seat 6 is directly designed to be smaller than the inner side of the positioning grooves b01.

[0096] In other embodiments, the positioning grooves b01 are arranged only on the sub-cup seat 6.

[0097] 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.

[0098] As shown in the embodiments of Figure 3 , Figure 11 , Figure 12 , Figure 15 , Figure 16 and Figure 19 , the positioning groove b01 on the sub-cup assembly 4 is formed by the inward recess of the position of the spoiler rib b01' corresponding to the outer wall of the sub-cup 4.1.
