Description

Technical Field

[0001] This utility model relates to the field of cooking equipment technology, and more specifically, to a cooking device. Background Technology

[0002] Current stand mixers use belts to drive the output shaft connecting the food preparation components to the motor. The internal drive components of the stand mixer occupy a lot of space, resulting in a large overall size and taking up a significant amount of space in the kitchen. Utility Model Content

[0003] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0004] In view of this, the present invention proposes a cooking device, comprising: a housing; a drive motor located inside the housing, the drive motor including a first output shaft and a second output shaft; a planetary gear reduction assembly connected to the second output shaft; and a third output shaft connected to the planetary gear reduction assembly, wherein the second output shaft drives the third output shaft to rotate through the planetary gear reduction assembly, the output speed of the third output shaft is less than the output speed of the first output shaft, and the first and third output shafts are used to connect cooking components.

[0005] The drive motor includes two output shafts, a first output shaft and a second output shaft. A planetary gear reducer is mounted on the second output shaft, and a third output shaft is mounted on the planetary gear reducer. The second output shaft drives the planetary gear reducer, which in turn drives the third output shaft. The planetary gear reducer enables speed reduction; by placing it between the second and third output shafts, the rotational speed of the third output shaft can be lower than that of the second output shaft. Furthermore, the planetary gear reducer allows for a larger transmission ratio, making the third output shaft suitable for applications requiring high torque output.

[0006] The planetary gear reduction assembly adjusts the output speed so that the output speed of the third output shaft is less than that of the first output shaft, enabling the cooking device to achieve at least two speed driving functions. The first and third output shafts are used to connect the cooking components, and the corresponding cooking components can be installed on the first or third output shaft according to the usage requirements such as speed and torque.

[0007] In this solution, the second output shaft of the drive motor drives the third output shaft to rotate through the planetary gear reduction assembly. The drive system consisting of the drive motor, the planetary gear reduction assembly, and the third output shaft is integrated together. Compared with the belt drive method in related technologies, which sets up a belt drive between the motor and the output shaft, the drive system in this solution has a more compact structure, which reduces the structural complexity and volume of the drive system. The space occupied by the drive system is reduced, and the size of the cooking equipment can also be reduced, saving kitchen space for users and making it easier for users to move and store the cooking equipment.

[0008] In addition, the cooking device according to the above-mentioned technical solution provided by this utility model may also have the following additional technical features:

[0009] In some technical solutions, the first output shaft and the third output shaft may optionally extend in opposite directions.

[0010] The first and third output shafts of the drive motor are typically two output shafts extending in opposite directions, with the axes of the first and second output shafts collinear. The planetary gear reduction assembly in this design can achieve speed reduction without changing the output direction of the output shafts. Therefore, a steering structure is not required within the planetary gear reduction assembly, simplifying its structure and further reducing the space occupied by the drive system.

[0011] In some technical solutions, optionally, the planetary gear reduction assembly includes: a central gear connected to a second output shaft; multiple planetary gears distributed circumferentially along the central gear and meshing with the central gear; a gear ring meshing with the inner ring of the gear ring; a planet carrier rotatably connected to the planetary gears, the multiple planetary gears driving the planet carrier to rotate; and a third output shaft connected to the planet carrier, the planet carrier driving the third output shaft to rotate.

[0012] A central gear is mounted on the second output shaft, rotating synchronously with it. Located at the center of multiple planetary gears, the central gear meshes with the planetary gears, driving their rotation. These planetary gears are mounted within a gear ring, with meshing teeth on the inner ring to allow them to engage. During the rotation of the central gear, the planetary gears not only rotate on their own axes but also revolve around it. The planetary gears are mounted on a planet carrier, which has multiple shafts. The planetary gears rotate relative to the planet carrier along these shafts, thus driving the planet carrier's rotation. A third output shaft is connected to the planet carrier, driving its rotation. After transmission through the central gear, planetary gears, and planet carrier, the third output shaft rotates at a lower speed than the second output shaft, making it suitable for low-speed, high-torque applications.

[0013] In some technical solutions, optionally, the side of the third output shaft is provided with a first limiting surface, the planetary gear reduction assembly is provided with a shaft hole, and the inner wall of the shaft hole is provided with a second limiting surface. When the third output shaft is inserted into the shaft hole, the first limiting surface and the second limiting surface fit together so that the third output shaft rotates with the planetary gear reduction assembly.

[0014] The planetary gear reducer assembly has a shaft hole into which the third output shaft can be inserted. A first limiting surface is machined on the third output shaft, and a second limiting surface is machined on the inner wall of the shaft hole. When the first limiting surface is in contact with the second limiting surface, the first and second limiting surfaces mutually limit each other, preventing the third output shaft from rotating relative to the planetary gear reducer assembly, and allowing the third output shaft to rotate synchronously with the planetary gear reducer assembly.

[0015] In some technical solutions, the cooking device may optionally include: a transmission assembly connected to a third output shaft, the third output shaft being used to drive the transmission assembly to rotate; and a fourth output shaft connected to the transmission assembly, the transmission assembly being used to drive the fourth output shaft to rotate, the fourth output shaft and the third output shaft having different extension directions.

[0016] A transmission assembly is mounted on the third output shaft, and the fourth output shaft is connected to the transmission assembly. The third output shaft drives the fourth output shaft to rotate through the transmission assembly. The fourth output shaft is used to connect the cooking components. Therefore, users can install the cooking components on the first, third, or fourth output shaft according to their needs. The transmission assembly and the fourth output shaft are integrated on the third output shaft, enabling the cooking device in this solution to achieve three-axis output. Furthermore, the fourth and third output shafts extend in different directions, so even if cooking components are mounted on both the fourth and third output shafts simultaneously, the cooking components are less likely to interfere with each other, meeting the user's needs in different scenarios.

[0017] In some technical solutions, optionally, the output speed of the third output shaft is greater than or equal to the output speed of the fourth output shaft.

[0018] In one possible application, the output speed of the third output shaft is the same as that of the fourth output shaft. After being driven by the transmission component, the output speed of the fourth output shaft remains unchanged. The only difference between the third and fourth output shafts is the position where the cooking components are mounted.

[0019] In one possible application, the output speed of the third output shaft is greater than that of the fourth output shaft. Therefore, in this solution, the cooking device achieves a three-axis output function, that is, the first output shaft is a high-speed output shaft, the third output shaft is a medium-speed output shaft, and the fourth output shaft is a low-speed output shaft. This solution enables the cooking device to achieve the function of three speed outputs in a small size, meeting the different usage needs of users.

[0020] In some technical solutions, optionally, the transmission assembly includes: a first transmission gear sleeved on a third output shaft, the first transmission gear rotating synchronously with the third output shaft; a second transmission gear meshing with the first transmission gear; a first bevel gear coaxially driving with the second transmission gear; a second bevel gear meshing with the first bevel gear, the second bevel gear sleeved on a fourth output shaft, the fourth output shaft rotating synchronously with the second bevel gear.

[0021] The first transmission gear is mounted on the third output shaft and rotates synchronously with it. The second transmission gear meshes with the first transmission gear, allowing it to drive the second transmission gear to rotate. The first bevel gear and the second transmission gear are coaxially driven, enabling the second transmission gear to drive the first bevel gear to rotate. The second bevel gear meshes with the first bevel gear and is mounted on the fourth output shaft. The first bevel gear drives the second bevel gear to rotate, which in turn drives the fourth output shaft to rotate, thus achieving transmission from the third output shaft to the fourth output shaft.

[0022] When the first and second bevel gears mesh with each other, the extension directions of the third and fourth output shafts can be different, thus distributing the third and fourth output shafts in a staggered manner, making it easier for users to assemble different cooking components on the third and fourth output shafts.

[0023] In some technical solutions, the cooking device may optionally include: a gearbox located within the housing, the gearbox including a first receiving portion and a second receiving portion, the thickness of the first receiving portion being greater than the thickness of the second receiving portion, a first bevel gear and a second bevel gear located within the first receiving portion, and a first transmission gear located within the second receiving portion.

[0024] The transmission assembly is installed inside the gearbox, which is used to connect the transmission assembly and maintain its structure, ensuring the structural stability of the transmission assembly so that it can stably perform its transmission function.

[0025] The first bevel gear and the second bevel gear have different axial directions, so the first bevel gear and the second bevel gear occupy a large space in the thickness direction of the gearbox. The thickness of the first receiving part in the gearbox is large, so the first bevel gear and the second bevel gear are installed in the first receiving part. The first transmission gear occupies less space in the thickness direction, so the first transmission gear is installed in the second receiving part with a smaller thickness. This makes the size of the gearbox compatible with the internal transmission structure, which is beneficial to improving space utilization.

[0026] In some technical solutions, the housing may optionally include: a base; a support portion, one end of which is connected to the base; and a mounting portion, one end of which is connected to the other end of the support portion, forming a cooking zone between the mounting portion and the base, with the drive motor, planetary gear reduction assembly, and third output shaft located within the mounting portion.

[0027] The support section raises the mounting section above the base, thereby creating a cooking zone between the support section and the base, which provides space for the container.

[0028] The drive motor, planetary gear reduction assembly, and third output shaft are located inside the mounting section. When the cooking component is installed on the third output shaft, the cooking component can extend into the container to process the ingredients.

[0029] Because the transmission structure between the drive motor and the third output shaft occupies less space, the drive motor, planetary gear reduction assembly, and third output shaft can be installed in the mounting section at the same time, without having to set part of the transmission structure in the support section. The support section can only serve as a support or to store other components, which helps to improve the space utilization rate inside the cooking equipment.

[0030] In some technical solutions, the width of the support part may be smaller than the width of the mounting part.

[0031] Since the drive structure of the cooking equipment does not need to be assembled inside the support, the width of the support can be appropriately reduced, thereby reducing the size of the cooking equipment in the width direction and reducing the volume of the cooking equipment, saving kitchen space for users and making it easier for users to move and store the cooking equipment.

Detailed Implementation

[0045] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0046] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0047] The following reference Figures 1 to 9This invention describes a cooking apparatus provided according to some embodiments of the present invention.

[0048] Combination Figure 1 and Figure 2 As shown in the embodiment of this utility model, a cooking device is proposed, including: a housing 110, a drive motor 120, a planetary gear reduction assembly 130, and a third output shaft 140. The drive motor 120 is located inside the housing 110. The drive motor 120 includes a first output shaft 121 and a second output shaft 122. The planetary gear reduction assembly 130 is connected to the second output shaft 122, and the third output shaft 140 is connected to the planetary gear reduction assembly 130. The second output shaft 122 drives the third output shaft 140 to rotate through the planetary gear reduction assembly 130. The output speed of the third output shaft 140 is less than the output speed of the first output shaft 121. The first output shaft 121 and the third output shaft 140 are used to connect the cooking component 180.

[0049] The drive motor 120 includes two output shafts: a first output shaft 121 and a second output shaft 122. A planetary gear reducer assembly 130 is mounted on the second output shaft 122, and a third output shaft 140 is mounted on the planetary gear reducer assembly 130. The second output shaft 122 drives the planetary gear reducer assembly 130 to rotate, and the planetary gear reducer assembly 130 drives the third output shaft 140 to rotate. The planetary gear reducer assembly 130 enables speed reduction. By placing the planetary gear reducer assembly 130 between the second output shaft 122 and the third output shaft 140, the rotational speed of the third output shaft 140 can be lower than that of the second output shaft 122. Furthermore, the planetary gear reducer assembly 130 can achieve a larger transmission ratio, making the third output shaft 140 suitable for use in scenarios requiring high torque output.

[0050] The planetary gear reduction assembly 130 adjusts the output speed so that the output speed of the third output shaft 140 is less than the output speed of the first output shaft 121, so that the cooking device can achieve at least two speed driving functions. The first output shaft 121 and the third output shaft 140 are used to connect the cooking component 180. According to the usage requirements such as speed and torque, the corresponding cooking component 180 can be installed on the first output shaft 121 or the third output shaft 140.

[0051] In this solution, the second output shaft 122 of the drive motor 120 drives the third output shaft 140 to rotate through the planetary gear reduction assembly 130. The drive system composed of the drive motor 120, the planetary gear reduction assembly 130, and the third output shaft 140 is integrated together. Compared with the belt drive method in related technologies, the drive system in this solution has a more compact structure, which reduces the structural complexity and volume of the drive system. The space occupied by the drive system is reduced, and the size of the cooking equipment can also be reduced, saving kitchen space for users and making it convenient for users to move and store the cooking equipment.

[0052] The cooking device 100 also includes a bearing 200 for supporting the second output shaft 122.

[0053] like Figure 2 As shown, in some embodiments, optionally, the first output shaft 121 and the third output shaft 140 extend in opposite directions.

[0054] The first output shaft 121 and the third output shaft 140 of the drive motor 120 are typically two output shafts extending in opposite directions, and their axes are collinear. The planetary gear reduction assembly 130 in this design can achieve speed reduction without changing the output direction of the output shafts. Therefore, a steering structure is not required within the planetary gear reduction assembly 130, simplifying its structure and further reducing the space occupied by the drive system.

[0055] In one possible application, the first output shaft 121, the second output shaft 122, and the third output shaft 140 are arranged vertically on the whole machine.

[0056] Combination Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments, optionally, the planetary gear reduction assembly 130 includes: a central gear 131, planetary gears 132, a ring gear 133, and a planet carrier 134. The central gear 131 is connected to the second output shaft 122, and there are multiple planetary gears 132, which are arranged circumferentially around the central gear 131. Figure 5 As indicated by the arrow at point C, planetary gears 132 mesh with the central gear 131, and planetary gears 132 mesh with the inner ring of the gear ring 133. Planetary gears 132 are rotatably connected to the planet carrier 134. Multiple planetary gears 132 are used to drive the planet carrier 134 to rotate. The third output shaft 140 is connected to the planet carrier 134, and the planet carrier 134 is used to drive the third output shaft 140 to rotate.

[0057] A central gear 131 is fitted onto the second output shaft 122, and the central gear 131 rotates synchronously with the second output shaft 122. The central gear 131 is located at the center of multiple planetary gears 132, and the central gear 131 meshes with the planetary gears 132, enabling the central gear 131 to drive the planetary gears 132 to rotate. The multiple planetary gears 132 are installed inside a gear ring 133, and meshing teeth are provided on the inner ring of the gear ring 133, allowing the planetary gears 132 to mesh with the inner ring of the gear ring 133. During the rotation of the central gear 131, the planetary gears 132 not only rotate on their own axes, but also revolve around the central gear 131. The multiple planetary gears 132 are mounted on a planet carrier 134, which has multiple rotating shafts. The planetary gears 132 are mounted on the rotating shafts and can rotate relative to the planet carrier 134 along the rotating shafts. When the multiple planetary gears 132 revolve around the planet carrier 134, they can drive the planet carrier 134 to rotate. The third output shaft 140 is connected to the planet carrier 134. When the planet carrier 134 rotates, it can drive the third output shaft 140 to rotate. After the transmission through the center gear 131, planet gear 132 and planet carrier 134, the speed of the third output shaft 140 is lower than that of the second output shaft 122, making the third output shaft 140 suitable for low-speed, high-torque applications.

[0058] Combination Figure 7 and Figure 8 As shown, in some embodiments, optionally, the side of the third output shaft 140 is provided with a first limiting surface 141, the planetary gear reduction assembly 130 is provided with a shaft hole 1321, and the inner wall of the shaft hole 1321 is provided with a second limiting surface 1322. When the third output shaft 140 is inserted into the shaft hole 1321, the first limiting surface 141 and the second limiting surface 1322 are in contact, so that the third output shaft 140 rotates with the planetary gear reduction assembly 130.

[0059] The planetary gear reducer assembly 130 is provided with a shaft hole 1321, into which the third output shaft 140 can be inserted. A first limiting surface 141 is machined on the third output shaft 140, and a second limiting surface 1322 is machined on the inner wall of the shaft hole 1321. When the first limiting surface 141 is in contact with the second limiting surface 1322, the first limiting surface 141 and the second limiting surface 1322 mutually limit each other, preventing the third output shaft 140 from rotating relative to the planetary gear reducer assembly 130, and allowing the third output shaft 140 to rotate synchronously with the planetary gear reducer assembly 130.

[0060] For example, the first limiting surface 141 and the second limiting surface 1322 can be planar or arc-shaped. When the first limiting surface 141 and the second limiting surface 1322 are arc-shaped, the curvature of the first limiting surface 141 and the second limiting surface 1322 is the same, and the curvature of the first limiting surface 141 is less than the curvature of other positions in the third output shaft 140.

[0061] Combination Figure 4 and Figure 6 As shown, in some embodiments, the cooking device may optionally further include: a transmission assembly 150 and a fourth output shaft 160. The transmission assembly 150 is connected to a third output shaft 140, which drives the transmission assembly 150 to rotate. The fourth output shaft 160 is connected to the transmission assembly 150, which drives the fourth output shaft 160 to rotate. The fourth output shaft 160 and the third output shaft 140 have different extending directions.

[0062] A transmission assembly 150 is mounted on the third output shaft 140, and a fourth output shaft 160 is connected to the transmission assembly 150. The third output shaft 140 drives the fourth output shaft 160 to rotate through the transmission assembly 150. The fourth output shaft 160 is used to connect the cooking component 180. Therefore, according to their usage needs, users can install the cooking component 180 on the first output shaft 121, the third output shaft 140, or the fourth output shaft 160. The transmission assembly 150 and the fourth output shaft 160 are integrated on the third output shaft 140, enabling the cooking device in this solution to achieve three-axis output. Furthermore, the fourth output shaft 160 and the third output shaft 140 extend in different directions, so even if the cooking component 180 is mounted on both the fourth output shaft 160 and the third output shaft 140, the cooking components 180 are unlikely to interfere with each other, meeting the usage needs of users in different scenarios.

[0063] The third output shaft 140 and the fourth output shaft 160 are decomposed into two directions: lateral and vertically downward.

[0064] In some embodiments, the output speed of the third output shaft 140 may be greater than or equal to the output speed of the fourth output shaft 160.

[0065] In one possible application, the output speed of the third output shaft 140 is the same as that of the fourth output shaft 160. After being driven by the transmission assembly 150, the output speed of the fourth output shaft 160 remains unchanged. The only difference between the third output shaft 140 and the fourth output shaft 160 is the position where the cooking component 180 is mounted.

[0066] In one possible application, the output speed of the third output shaft 140 is greater than that of the fourth output shaft 160. Therefore, in this solution, the cooking device realizes the three-axis output function, that is, the first output shaft 121 is a high-speed output shaft, the third output shaft 140 is a medium-speed output shaft, and the fourth output shaft 160 is a low-speed output shaft. This solution enables the cooking device to achieve the function of three speed outputs in a small size, meeting the different usage needs of users.

[0067] Combination Figure 4 and Figure 6 As shown, in some embodiments, optionally, the transmission assembly 150 includes: a first transmission gear 151, a second transmission gear 152, a first bevel gear 153, and a second bevel gear 154. The first transmission gear 151 is sleeved on a third output shaft 140, and the first transmission gear 151 rotates synchronously with the third output shaft 140. The second transmission gear 152 meshes with the first transmission gear 151. The first bevel gear 153 and the second transmission gear 152 are coaxially driven, and the second bevel gear 154 meshes with the first bevel gear 153. The second bevel gear 154 is sleeved on a fourth output shaft 160, and the fourth output shaft 160 rotates synchronously with the second bevel gear 154.

[0068] The first transmission gear 151 is mounted on the third output shaft 140, and rotates synchronously with the third output shaft 140. The second transmission gear 152 meshes with the first transmission gear 151, and the first transmission gear 151 can drive the second transmission gear 152 to rotate. The first bevel gear 153 and the second transmission gear 152 are coaxially driven, so that the second transmission gear 152 can drive the first bevel gear 153 to rotate. The second bevel gear 154 meshes with the first bevel gear 153, and is mounted on the fourth output shaft 160. The first bevel gear 153 drives the second bevel gear 154 to rotate, and the second bevel gear 154 drives the fourth output shaft 160 to rotate, thereby realizing the transmission from the third output shaft 140 to the fourth output shaft 160.

[0069] When the first bevel gear 153 and the second bevel gear 154 are meshed together, the extension directions of the third output shaft 140 and the fourth output shaft 160 can be different, thereby distributing the third output shaft 140 and the fourth output shaft 160 in a staggered manner, which makes it convenient for the user to assemble different cooking components 180 on the third output shaft 140 and the fourth output shaft 160.

[0070] In this embodiment, there are two second transmission gears 152, one of which meshes with the first transmission gear 151. The two transmission gears mesh with each other, and the first bevel gear 153 rotates synchronously with the one of the two second transmission gears 152 that is furthest from the first transmission gear 151. Of course, in other embodiments, the number of second transmission gears 152 can be one or more than two.

[0071] Combination Figure 3 , Figure 4 and Figure 9 As shown, in some embodiments, optionally, the cooking device further includes: a gearbox 170, the gearbox 170 being located within the housing 110, the gearbox 170 including a first receiving portion 171 and a second receiving portion 172, the thickness of the first receiving portion 171 being ( Figure 9The arrow at point H points to indicate the thickness direction of the first receiving portion 171 and the second receiving portion 172. The thickness of the first receiving portion 171 is greater than that of the second receiving portion 172. The first bevel gear 153 and the second bevel gear 154 are located inside the first receiving portion 171, and the first transmission gear 151 is located inside the second receiving portion 172.

[0072] The transmission assembly 150 is installed inside the gearbox 170. The gearbox 170 is used to connect the transmission assembly 150 and maintain the structure of the transmission assembly 150, ensuring the structural stability of the transmission assembly 150, so that the transmission assembly 150 can stably realize the transmission function.

[0073] The first bevel gear 153 and the second bevel gear 154 have different axial directions. Therefore, the first bevel gear 153 and the second bevel gear 154 occupy a large space in the thickness direction of the gearbox 170. The first receiving part 171 in the gearbox 170 has a large thickness. The first bevel gear 153 and the second bevel gear 154 are installed in the first receiving part 171. The first transmission gear 151 occupies a small space in the thickness direction. Therefore, the first transmission gear 151 is installed in the second receiving part 172 with a smaller thickness. This makes the size of the gearbox 170 compatible with the internal transmission structure, which is beneficial to improving space utilization.

[0074] In this embodiment, the gearbox 170 includes an upper housing 173 and a lower housing 174, with a first transmission gear 151, a second transmission gear 152, a first bevel gear 153, and a second bevel gear 154 located between the upper housing 173 and the lower housing 174.

[0075] like Figure 1 As shown, in some embodiments, optionally, the housing 110 includes: a base 111, a support portion 112, and a mounting portion 113. One end of the support portion 112 is connected to the base 111, and one end of the mounting portion 113 is connected to the other end of the support portion 112. A cooking zone 114 is formed between the mounting portion 113 and the base 111. The drive motor 120, the planetary gear reduction assembly 130, and the third output shaft 140 are located inside the mounting portion 113.

[0076] The support 112 raises the mounting part 113 above the base 111, thereby forming a cooking area 114 between the support 112 and the base 111, which provides a place for the container 190.

[0077] The drive motor 120, planetary gear reduction assembly 130 and third output shaft 140 are located in the mounting part 113. When the cooking component 180 is installed on the third output shaft 140, the cooking component 180 can extend into the container 190 to process the food.

[0078] Since the transmission structure between the drive motor 120 and the third output shaft 140 occupies less space, the drive motor 120, the planetary gear reduction assembly 130 and the third output shaft 140 can be installed in the mounting part 113 at the same time, without having to set part of the transmission structure in the support part 112. The support part 112 can only serve as a support or to store other components, which is beneficial to improving the space utilization rate inside the cooking equipment.

[0079] In one possible application, the cooking component 180 in this embodiment is a rotating wheel assembly connected to the third output shaft 140. At least a portion of the rotating wheel assembly extends into the cooking zone 114, and the third output shaft 140 drives the rotating wheel assembly to rotate, thereby processing the ingredients.

[0080] The rotating wheel assembly only needs to be able to achieve the rotation function, and the specific structure is not limited. For example, the rotating wheel assembly includes: a drive gear 181, an outer gear ring 182, an inner gear 183, and a stirring shaft 184. The drive gear 181 is sleeved on the third output shaft 140. The drive gear 181 meshes with the inner gear 183. The inner gear 183 also meshes with the inner ring of the outer gear ring 182. The inner gear 183 is sleeved on the stirring shaft 184, so that the inner gear 183 can not only revolve around the central axis, but also rotate on its own axis.

[0081] Of course, the first output shaft 121, the third output shaft 140 and the fourth output shaft 160 can also be connected to other cooking components.

[0082] like Figure 1 As shown, in some embodiments, optionally, the width of the support portion 112 is smaller than the width of the mounting portion 113. Figure 1 The arrow at point W points in the middle, indicating the width direction of the support part 112 and the mounting part 113.

[0083] Since the drive structure of the cooking equipment does not need to be assembled inside the support part 112, the width of the support part 112 can be appropriately reduced, thereby reducing the size of the cooking equipment in the width direction and reducing the volume of the cooking equipment, saving kitchen space for users and making it convenient for users to move and store the cooking equipment.
