Technical Field

[0001] The present invention relates to the technical field of household appliances, and in particular, to a cooking machine. Background Art

[0002] In recent years, in order to facilitate cooking and improve the quality of life, more and more household appliances for kitchen use have gradually entered more families. As a household appliance that can realize functions such as grinding, stirring, and shredding, a cooking machine provides convenience for food material processing. However, in actual use of the cooking machine, "non-uniform particle size" is a pain point that users frequently feedback and complain about, reducing the user's cooking experience. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems in the related art to some extent.

[0004] To this end, an embodiment of the present invention provides a cooking machine, which improves the situation of "food materials sticking to the wall", enables the blade to effectively cut the food materials, and improves the particle uniformity during food material processing.

[0005] The cooking machine according to the embodiment of the present invention includes:

[0006] A main body, the main body includes a second container and a first container at least partially located in the second container, and a meshing portion is provided on the inner side of the opening of the first container;

[0007] A whipping assembly, the whipping assembly includes a whipping knife, the whipping knife is rotatably arranged in the first container for whipping the food materials in the first container;

[0008] A machine head, the machine head is detachably assembled to the main body, the machine head includes a driving motor and a first transmission assembly, wherein the first transmission assembly includes a sun gear and a planetary gear, the output shaft of the driving motor, the sun gear and the planetary gear are sequentially drivingly connected, and the sun gear is connected to the whipping assembly to drive the whipping knife to rotate, and the planetary gear engages with the meshing portion to drive the first container to rotate while accompanied by vibration.

[0009] The cooking machine according to the embodiment of the present invention improves the situation of "food materials sticking to the wall", enables the blade to effectively cut the food materials, and improves the particle uniformity during food material processing.

[0010] In some embodiments, a step is provided at the opening of the second container, an annular flange is provided at the opening of the first container, the flange overlaps the step, and the inner diameter of the flange is smaller than the inner diameter of the step, and the outer diameter of the flange is smaller than the outer diameter of the step.

[0011] The lap joint and corresponding dimensional limitations of the annular flanging and the step only better limit the degree of freedom of downward movement of the first container relative to the second container, so that the first container can have relative displacement upward and laterally relative to the second container, enabling the first container to have vibration space in the lateral and vertical directions, meeting the usage requirements of rotation and vibration of the first container relative to the second container.

[0012] In some embodiments, a plurality of bumps are provided at the bottom of the flanging, and the plurality of bumps are arranged at intervals along the circumferential direction of the flanging. The flanging is lapped on the step through the bumps.

[0013] On the one hand, the provision of the bumps can achieve point contact between the flanging and the step, thereby reducing the frictional force between the flanging and the step and facilitating the rotation of the first container relative to the second container; on the other hand, the bumps also have better elastic properties, and this elastic property will directly act on the step, thereby increasing the instability of the local contact between the flanging and the step, and further enhancing the relative vibration effect between the first container and the second container.

[0014] In some embodiments, the main body further includes a heating component, and the heating component is provided at the bottom of the second container, thus meeting the usage requirements of stewing or steaming food materials.

[0015] In some embodiments, the meshing portion is a first gear ring, the planetary gear includes at least one gear, and the planetary gear meshes between the sun gear and the first gear ring. Thereby, the first container can always be meshed with the second container when rotating, ensuring the structural stability of the assembly of the first container. Secondly, the first gear ring can also play a role in restricting the lateral vibration amount of the first container, avoiding the situation of excessive vibration amount of the first container.

[0016] In some embodiments, the machine head further includes a machine head housing, a lower bracket and a machine head cover. One end of the machine head housing is provided with an opening, the lower bracket is located inside the opening, and the driving motor is provided above the lower bracket, the planetary gear is provided below the lower bracket, a through hole for the sun gear to pass through is provided at the center of the lower bracket, the machine head cover is assembled at the opening of the machine head housing, and a slot for the planetary gear to pass through and connect with the meshing portion is provided on the machine head cover. Thereby, it facilitates the assembly of the planetary gear and the sun gear, and also realizes the modularization and integration of the machine head, avoiding the situation of scattered components and improving the convenience for users.

[0017] In some embodiments, the planetary gear is provided with a gear shaft, a first groove is correspondingly provided on the lower bracket, a second groove is correspondingly provided on the machine head cover, and the diameter of the first groove and / or the second groove is greater than the diameter of the gear shaft.

[0018] As a result, the gear shaft can move axially and laterally within the first groove and the second groove, thus meeting the usage requirements of the vibration of the first container and further enhancing the vibration effect of the first container.

[0019] In some embodiments, one of the lower bracket and the machine head cover is provided with a central shaft, and the other is provided with a corresponding mating groove. The planetary gear is provided with a central through hole, and the central through hole is sleeved on the central shaft, and the diameter of the central through hole is larger than the diameter of the central shaft.

[0020] As a result, the planetary gear can undergo lateral displacement relative to the central shaft, thus meeting the usage requirements of the vibration of the first container and further enhancing the vibration effect of the first container.

[0021] In some embodiments, the distance between the lower bracket and the machine head cover is greater than the thickness of the planetary gear. Thereby, space can be provided for the up-and-down vibration of the planetary gear, fully meeting the usage requirements of the vibration of the first container.

[0022] In some embodiments, a rotation prevention groove is provided at the center of the sun gear, and the cutter shaft of the whipping knife is detachably assembled in the rotation prevention groove. Thereby, the driving assembly of the whipping knife is facilitated, and the subsequent cleaning of the whipping knife is also facilitated. In addition, this assembly makes the rotation direction of the whipping knife the same as that of the sun gear, while the first container rotates in the opposite direction to the whipping knife because it meshes with the planetary gear. Thereby, the relative rotation speed between the first container and the whipping knife can be increased, and further, the whipping effect on the food materials can be increased, ensuring the uniformity of the particles of the food materials after whipping.

[0042] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0043] The present invention is based on the inventor's discovery and recognition of the following facts and problems:

[0044] Through research, it is found that there is a situation of "ingredients sticking to the wall" when the cooking machine is in use. At this time, the blade of the cooking machine cannot effectively cut the ingredients sticking to the wall, resulting in the problem of uneven particle size during the food processing process.

[0045] To solve the above problem of uneven particle size, the R & D personnel have also proposed some solutions. For example, during the whipping process, the blade moves up and down. The blade moving up and down will increase the whipping range of the blade, thereby improving the uniformity of the particles. However, the above solution does not fundamentally solve the problem of ingredients sticking to the wall, so that the particle size of the processed ingredients still cannot reach the ideal effect.

[0046] The cooking machine according to the embodiment of the present invention includes a main body 1000, a whipping assembly 3000 and a machine head 2000. As Figure 1 shown, the machine head 2000 can be installed above the main body 1000, and the assembly of the machine head 2000 and the main body 1000 is a detachable assembly. For example, the machine head 2000 can be installed and fixed to the main body 1000 by means of clamping, screwing, etc.

[0047] As Figure 2 shown, the main body 1000 includes a first container 1002 for storing ingredients. The first container 1002 can be a cooking utensil, specifically a steamer. The top of the first container 1002 is open, and a meshing part 1002A is provided at the open top of the first container 1002. As Figure 3 shown, the meshing part 1002A can be provided inside the first container 1002. The meshing part 1002A can specifically be a toothed ring, and the meshing part 1002A extends along the circumferential direction of the first container 1002 and closes into a circle. After the machine head 2000 is installed on the main body 1000, the machine head 2000 can block the open mouth of the first container 1002.

[0048] The main body 1000 further includes a second container 1003. The second container 1003 is a cooking utensil, specifically a saucepan. The first container 1002 can be fitted inside the second container 1003. The second container 1003 is used to store a heating medium, and the heating medium can be water, etc.

[0049] like Figure 4 As shown, the whipping assembly 3000 includes a whipping blade 3001 and a mounting shaft 3002. The mounting shaft 3002 may be substantially a circular shaft, and the whipping blade 3001 may be fixedly mounted on the outer peripheral side of the mounting shaft 3002. When in use, the whipping blade 3001 is located in the first container 1002 and may rotate around the axis of the mounting shaft 3002 in the first container 1002. The ingredients in the first container 1002 may be minced by the cutting action of the whipping blade 3001 when rotating. The ingredients may specifically be vegetables, beans, meat, etc.

[0050] like Figure 5 As shown, the machine head 2000 includes a driving motor 2002 and a first transmission component 2003. The driving motor 2002 can be assembled in the machine head 2000. The motor shaft of the driving motor 2002 is connected to the input end of the first transmission component 2003. Thus, the first transmission component 2003 can be driven by the rotation of the driving motor 2002.

[0051] It should be noted that the first transmission component 2003 has two output ends, which are the sun gear 2003B and the planetary gear 2003A, wherein the sun gear 2003B can be connected to the mounting shaft 3002 of the beating component 3000. When the first transmission component 2003 is running, the sun gear 2003B can act on the beating component 3000 and drive the beating knife 3001 to rotate, thereby achieving the mincing of the food.

[0052] The planetary gear 2003A is located in the first container 1002 and is engaged with the meshing portion 1002A of the first container 1002. When the first transmission assembly 2003 is running, the planetary gear 2003A can act on the first container 1002 and drive the first container 1002 to rotate. It should be noted that, due to the meshing of the first container 1002 and the planetary gear 2003A, there is a certain assembly gap or error, and the first container 1002 will also be accompanied by vibration or shaking while rotating. In the food processor of the embodiment of the present invention, the whipping assembly 3000 and the first container 1002 are both connected to the first transmission assembly 2003 by transmission, and the whipping assembly 3000 and the first container 1002 can be driven to rotate at the same time by the same drive motor 2002, thereby simplifying the overall structure and reducing the corresponding components, which plays a role in reducing costs.

[0053] Secondly, the first container 1002 is driven by the planetary gear 2003A through meshing fit. This assembly method not only meets the usage requirement of driving the first container 1002 to rotate, but also due to the assembly error and the gaps between the assembled teeth, the first container 1002 will vibrate and shake while rotating. This complex and irregular motion form makes the sticky food materials on the inner wall of the first container 1002 easily fall off, thus avoiding the situation of "food sticking to the wall" in the prior art, and further improving the uniformity of food processing and the user experience.

[0054] In some embodiments, as Figure 14 shown, a step 1003A is provided at the opening of the second container 1003. The step 1003A can be annular and extend circumferentially along the second container 1003 to form a closed loop. As Figure 13 shown, the opening of the first container 1002 is provided with an annular flange 1002B. The flange 1002B overlaps the step 1003A and is rotatable relative to the step 1003A. The inner diameter of the flange 1002B is smaller than the inner diameter of the step 1003A, and the outer diameter of the flange 1002B is smaller than the outer diameter of the step 1003A.

[0055] Thus, the overlapping fit between the flange 1002B and the step 1003A only well restricts the degree of freedom of the downward movement of the first container 1002 relative to the second container 1003, so that the first container 1002 can move relatively upward relative to the second container 1003. And the corresponding radial dimension limitation enables the first container 1002 to have a relative displacement in the transverse direction relative to the second container 1003, so that the first container 1002 has a transverse vibration space, meeting the usage requirements of the rotation and vibration of the first container 1002 relative to the second container 1003.

[0056] In some embodiments, a plurality of bumps 1002B1 are provided at the bottom of the flange 1002B. The plurality of bumps 1002B1 are arranged at intervals along the circumferential direction of the flange 1002B, and the flange 1002B overlaps the step 1003A through the bumps 1002B1.

[0057] For example, as Figure 13 shown, a plurality of bumps 1002B1 can be provided at the bottom of the flange 1002B. The plurality of bumps 1002B1 are arranged at intervals along the circumferential direction of the first container 1002. The bumps 1002B1 are in contact with the step 1003A to reduce the contact area between the flange 1002B and the step 1003A, thereby reducing the frictional force between the flange 1002B and the step 1003A when the first container 1002 rotates and improving the smoothness of rotation.

[0058] In addition, the bump 1002B1 also has better elastic properties, and this elastic property will directly act on the step 1003A, thereby increasing the instability of the local contact between the flanging 1002B and the step 1003A, and further enhancing the relative vibration effect between the first container 1002 and the second container 1003.

[0059] In some other embodiments, a plurality of balls can also be embedded at the bottom of the flanging 1002B, and the balls form the bump 1002B1. By means of the balls, rolling friction between the flanging 1002B and the step 1003A can be achieved, and the frictional effect can be further reduced.

[0060] In some embodiments, as Figure 12 and Figure 14 shown, the main machine 1000 includes a main machine housing 1001 and a heating component 1009. The second container 1003 is fixed inside the main machine housing 1001. As Figure 14 shown, the heating component 1009 is arranged inside the main body housing and can be located at the bottom of the second container 1003. The heating component 1009 can specifically be a heating tube. During use, the heating component 1009 can heat the heating medium in the second container 1003, and then the ingredients in the first container 1002 can be heated by means of the heated heating medium. This indirect heating method for the ingredients in the first container 1002 is relatively gentle, thus ensuring the cooking quality of the ingredients in the first container 1002.

[0061] Specifically, when the liquid ingredients are stored in the second container 1003, the ingredients in the first container 1002 can be steamed or stewed. For example, when there is more liquid ingredient stored in the second container 1003 to submerge the bottom of the first container 1002, the ingredients in the first container 1002 can be stewed.

[0062] When there is less liquid stored in the second container 1003 and the bottom of the first container 1002 is not submerged, the steam in the second container 1003 enters the first container 1002 successively through the interlayer between the first container 1002 and the second container 1003 and the gap between the flanging 1002B and the step 1003A, so as to steam the ingredients in the first container 1002.

[0063] In some embodiments, as Figure 3 shown, the engaging portion 1002A on the first container 1002 is a first toothed ring. The first toothed ring is arranged on the inner wall of the first container 1002 and adjacent to the top opening of the first container 1002, and the first toothed ring extends and closes along the circumferential direction of the first container 1002.

[0064] As Figure 6As shown, the planetary gear 2003A is provided with at least one. The sun gear 2003B is located within the first toothed ring and is concentrically arranged with the first toothed ring. The planetary gear 2003A meshes between the sun gear 2003B and the first toothed ring, that is, the sun gear 2003B and at least one planetary gear 2003A form a sun-planetary gear train.

[0065] Thereby, when the first container 1002 rotates, it can always mesh with the second container 1003, ensuring the structural stability of the assembly of the first container 1002. Secondly, the first toothed ring can also play a role in restricting the lateral vibration amount of the first container 1002, avoiding the situation where the vibration amount of the first container 1002 is too large.

[0066] In some embodiments, the drive motor 2002 is connected to the sun gear 2003B. For example, the motor shaft of the drive motor 2002 can be directly connected to the sun gear 2003B through a coupling, or can be in a non-rotating fit with the sun gear 2003B. During use, the drive motor 2002 can drive the sun gear 2003B to rotate, and the sun gear 2003B drives the first container 1002 to rotate through the planetary gear 2003A and the first toothed ring.

[0067] Each planetary gear 2003A will generate self-rotation and circumferential rotation around the sun gear 2003B under the rotation of the sun gear 2003B, and the rotation directions of the sun gear 2003B and the planetary gear 2003A are opposite, specifically as Figure 8 shown, thus meeting the use requirements of the reverse rotation drive of the first container 1002 and the whipping knife 3001.

[0068] For example, both the whipping knife 3001 and the first container 1002 can rotate circumferentially around the axis of the mounting shaft 3002. Among them, the whipping knife 3001 can rotate clockwise, and the first container 1002 can rotate counterclockwise. This design with opposite rotation directions can increase the tumbling and cutting frequency of the ingredients, further ensuring the cooking effect on the ingredients.

[0069] Secondly, this design of reverse rotation can also make the operating speeds of the drive motor 2002, the first transmission assembly 2003, the whipping assembly 3000, and the first container 1002 slower while achieving the corresponding tumbling and cutting frequencies. Thereby, the stability of the overall operation can be ensured, and the overall movement noise can also be at a lower decibel, improving the noise pollution during the operation of the cooking machine and further enhancing the user experience.

[0070] In addition, the design of reverse rotation is also beneficial to increasing the disturbance of the ingredients adhering to the inner wall of the first container 1002, thereby further improving the situation of ingredients sticking to the wall.

[0071] In some other embodiments, the rotation direction of the whipping blade 3001 and the rotation direction of the first container 1002 may also be the same, and the rotation speeds of the whipping blade 3001 and the first container 1002 are different. For example, both the first whipping blade 3001 and the first container 1002 may rotate clockwise, where the rotation speed of the first whipping blade 3001 may be relatively fast, while the rotation speed of the first container 1002 may be slower than that of the whipping blade 3001. Thus, the first container 1002 can be at a slower rotation speed, which is also beneficial to ensuring the overall structural stability.

[0072] In some embodiments, as Figure 7 shown, after the machine head 2000 and the main machine 1000 are installed, the sun gear 2003B can be non-rotatably assembled with the mounting shaft 3002 of the whipping assembly 3000, and each planetary gear 2003A can be located within the meshing portion 1002A and meshed with the meshing portion 1002A.

[0073] Specifically, a non-rotating groove 2003B1 may be provided in the middle of the sun gear 2003B, and a non-rotating portion 3002A may be provided at the top of the mounting shaft 3002 of the whipping assembly 3000. The non-rotating portion 3002A can be inserted and non-rotatably fitted in the non-rotating groove 2003B1, thereby enabling the transmission connection between the whipping assembly 3000 and the sun gear 2003B and also facilitating the disassembly of the whipping assembly 3000.

[0074] In some embodiments, as Figure 6 shown, the machine head 2000 includes a machine head housing 2001, a machine head cover 2005, an upper bracket 2006, and a lower bracket 2007. The machine head housing 2001 may be in a cylindrical shape, and an opening 2001A is provided at the bottom of the machine head housing 2001. The machine head cover 2005 can be fixed to the machine head housing 2001 by means of snap connection, fasteners, etc. and cover the opening 2001A of the machine head housing 2001. Thus, the overall sealing performance of the machine head 2000 is ensured, and it also plays a protective role.

[0075] As Figure 6 shown, both the upper bracket 2006 and the lower bracket 2007 may be in an annular shape. The upper bracket 2006 and the lower bracket 2007 are both provided inside the machine head housing 2001 and are arranged at intervals along the axial direction (up and down direction) of the machine head housing 2001. The lower bracket 2007 is adjacent to the machine head cover 2005, that is, the lower bracket 2007 is located below the upper bracket 2006, and the machine head cover 2005 is located below the lower bracket 2007.

[0076] The transmission frame 2004A and the first gear 2004B can generally be assembled between the upper bracket 2006 and the lower bracket 2007. The planetary gear 2003A can be rotatably assembled on the lower bracket 2007, and the planetary gear 2003A is generally located between the lower bracket 2007 and the machine head cover 2005. The sun gear 2003B passes through the lower bracket 2007 and meshes with the planetary gear 2003A located between the lower bracket 2007 and the machine head cover 2005.

[0077] As Figure 6 shown, the lower bracket 2007 is provided with a second toothed ring 2007A. The second toothed ring 2007A is arranged at the inner side wall of the lower bracket 2007 and is closed in a circle along the circumferential direction of the lower bracket 2007. Each first gear 2004B meshes between the second gear 2004C and the second toothed ring 2007A. The setting of the second toothed ring 2007A can realize the circumferential limit constraint on the first gear 2004B, thereby improving the assembly stability of the second transmission assembly 2004.

[0078] In some embodiments, as Figure 6 shown, a hollow boss 2005A is provided on the side of the machine head cover 2005 facing away from the drive motor 2002. The hollow boss 2005A can protrude downward from the machine head cover 2005 and form an inner cavity above.

[0079] The hollow boss 2005A is provided with an axially through hole 2005A1. The sun gear 2003B passes through the axially through hole 2005A1 and exposes from the bottom side of the hollow boss 2005A, thus facilitating the insertion and mating of the mounting shaft 3002 of the whipping assembly 3000 into the central mating hole (anti-rotation groove 2003B1) of the sun gear 2003B.

[0080] The planetary gear 2003A is located above the hollow boss 2005A and is installed in the inner cavity of the hollow boss 2005A. The peripheral wall of the hollow boss 2005A is provided with slots 2005A2. The number of slots 2005A2 is the same as the number of planetary gears 2003A. During assembly, multiple planetary gears 2003A can be assembled into multiple slots 2005A2 one by one. A part of each planetary gear 2003A extends through the corresponding slot 2005A2 to engage with the engaging portion 1002A of the first container 1002. Thereby ensuring the structural stability and facilitating the cooperation with the engaging portion 1002A.

[0081] In some embodiments, as Figure 9 shown, the planetary gear 2003A is provided with a gear shaft 2009. The gear shaft 2009 can be a circular shaft. The number of gear shafts 2009 is the same as the number of planetary gears 2003A. Each planetary gear 2003A is rotatably assembled on the gear shaft 2009.

[0082] As Figure 10 and Figure 11 shown, the lower bracket 2007 is provided with a first groove 2007B, the machine head cover 2005 is provided with a second groove 2005B, the top end of the gear shaft 2009 is rotatably fitted in the first groove 2007B, the bottom end of the gear shaft 2009 is rotatably fitted in the second groove 2005B, and the diameter of the first groove 2007B and / or the second groove 2005B is greater than the diameter of the gear shaft. Thus, the gear shaft 2009 can move axially and laterally in the first groove 2007B and the second groove 2005B, thereby meeting the use requirement of the vibration of the first container 1002 and further enhancing the vibration effect of the first container 1002.

[0083] During use, the gear shaft 2009 can rotate synchronously with the corresponding planetary gear 2003A, thus facilitating the rotational assembly and disassembly of the planetary gear 2003A.

[0084] For example, as Figure 11 shown, the distance between the lower bracket 2007 and the machine head cover 2005 is the distance L1, and the length dimension L2 of the gear shaft 2009 is greater than the distance L1, thereby achieving a limiting effect on the gear shaft 2009 and avoiding the situation of the gear shaft 2009 coming out.

[0085] Optionally, both the first groove 2007B and the second groove 2005B can be in the shape of a flared opening, that is, the groove width dimensions of the first groove 2007B and the second groove 2005B gradually decrease along the direction from the corresponding groove opening to the groove bottom, thereby facilitating the plug-in fit of the corresponding end portions of the gear shaft 2009.

[0086] In some embodiments, one of the lower bracket 2007 and the machine head cover 2005 is provided with a central shaft, and the other is provided with a corresponding mating groove. For example, the central shaft can be integrally formed with the lower bracket 2007, and the machine head cover 2005 can be provided with a mating groove, and the central shaft can be plugged and fitted in the mating groove. The planetary gear 2003A is provided with a central through hole, the central through hole is sleeved on the central shaft, and the diameter of the central through hole is greater than the diameter of the central shaft. Thus, the planetary gear 2003A can undergo lateral displacement relative to the central shaft, thereby meeting the use requirement of the vibration of the first container 1002 and further enhancing the vibration effect of the first container 1002.

[0087] In some embodiments, in the up and down direction, the distance between the lower bracket 2007 and the machine head cover 2005 is greater than the thickness of the planetary gear 2003A. Thus, space can be provided for the up and down vibration of the planetary gear 2003A, fully meeting the use requirement of the vibration of the first container 1002.

[0088] In some embodiments, as Figures 6 to 8As shown, there are three planetary gears 2003A, which are arranged at equal intervals around the axis of the sun gear 2003B. The three planetary gears 2003A can form an equilateral triangle structure, thus ensuring the structural stability of the drive. In some other embodiments, the number of planetary gears 2003A can also be one, two, four, etc. The number of planetary gears 2003A can be selectively designed according to the gap size between the sun gear 2003B and the meshing part 1002A.

[0089] In some embodiments, as Figure 5 shown, the cooking machine further includes a second transmission assembly 2004, and the second transmission assembly 2004 is arranged between the drive motor 2002 and the first transmission assembly 2003. As Figure 6 shown, the second transmission assembly 2004 includes a transmission frame 2004A, at least one first gear 2004B and a second gear 2004C. The sun gear 2003B is installed on the transmission frame 2004A. For example, the sun gear 2003B can be integrally formed with the transmission frame 2004A. In some other embodiments, the sun gear 2003B can also be fixed to the transmission frame 2004A by means of welding, fasteners, etc.

[0090] As Figure 6 shown, three first gears 2004B can be provided. The three first gears 2004B are all rotatably installed on the transmission frame 2004A, and the three first gears 2004B are arranged at equal intervals in the circumferential direction around the axis of the transmission frame 2004A. In some other embodiments, the number of first gears 2004B can also be two, four, five, etc.

[0091] As Figure 6 shown, the second gear 2004C is installed on the motor shaft of the drive motor 2002. The second gear 2004C is engaged between the three first gears 2004B and meshes with each first gear 2004B. The second gear 2004C and the first gear 2004B also form a sun-planet gear train, and the transmission frame 2004A is the planet carrier.

[0092] During use, the drive motor 2002 can drive the second gear 2004C to rotate. The three first gears 2004B will rotate self and rotate circumferentially around the second gear 2004C due to the meshing with the second gear 2004C. The sun gear 2003B and the transmission frame 2004A will rotate synchronously under the action of the circumferential rotation of the first gear 2004B, so as to realize the indirect drive of the sun gear 2003B.

[0093] It should be noted that in actual use, the rotational speed of the drive motor 2002 is relatively high. The setting of the second transmission assembly 2004 can reduce the transmission ratio output by the drive motor 2002 to the first transmission assembly 2003, which is beneficial to the structural stability of the overall drive.

[0094] In some embodiments, the output rotational speed of the second transmission assembly 2004 is from 500 r / min to 3500 r / min. For example, the output rotational speed of the second transmission assembly 2004 can be 500 r / min, 600 r / min, 800 r / min, 1000 r / min, 1500 r / min, 2000 r / min, 2500 r / min, 2700 r / min, 3000 r / min, 3500 r / min, etc. Within this output rotational speed range, it can not only meet the usage requirements for crushing food ingredients and ensure the cooking quality, but also avoid the situation of too high output rotational speed, which is beneficial to the operational stability and makes the overall operational noise relatively low.

[0095] In some embodiments, the ratio of the output rotational speed of the second transmission assembly 2004 to the output rotational speed of the first transmission assembly 2003 is not less than 3. Thus, it fully meets the usage requirements for the second transmission assembly 2004 to reduce the transmission ratio.

[0096] In some embodiments, as Figure 7 shown, the machine head 2000 is provided with a first coupler 1004, and the main machine 1000 is provided with a second coupler 2008. When the main machine 1000 is fixedly installed with the machine head 2000, the first coupler 1004 and the second coupler 2008 can be docked and electrically connected, so that the circuit of the drive motor 2002 on the machine head 2000 can be conducted, realizing the power support for the drive motor 2002.

[0097] In some embodiments, as Figure 12 shown, the main machine 1000 includes a control component 1005. The control component 1005 can be a circuit board. The control component 1005 is arranged inside the main machine 1000. When the drive motor 2002 is electrically connected through the first coupler 1004 and the second coupler 2008, the control component 1005 can also be electrically connected to the drive motor 2002, and the rotational control of the drive motor 2002 can be realized by means of the control component 1005.

[0098] In some embodiments, the inner cavity of the first container 1002 and the inner cavity of the second container 1003 are communicated through a channel 1007. The vapor generated by the heating component 1009 heating the heating medium flows from the second container 1003 into the first container 1002 through the channel 1007.

[0099] For example, a plurality of through holes may be provided on the container wall of the first container 1002. The plurality of through holes may be adjacent to the top of the first container 1002. The steam generated after heating the heating medium may enter the first container 1002 through the through holes, so that the heating of the top of the food ingredients in the first container 1002 can be realized simultaneously, avoiding the situation that the top of the food ingredients is easily undercooked.

[0100] In some embodiments, as Figure 14 shown, there are gaps between the step 1003A and the flanging 1002B, and between the outer peripheral wall of the first container 1002 and the inner peripheral wall of the second container 1003, forming part of the channel 1007. At this time, the channel 1007 bypasses the opening of the first container 1002. The steam generated by heating the heating medium can first wind around the upper part of the first container 1002, and then can enter the first container 1002 through the spaced space between two adjacent planetary gears 2003A. Thereby, the integrity of the first container 1002 is ensured, and the situation that the material in the first container 1002 enters the second container 1003 through the channel 1007 when the channel 1007 directly penetrates the container wall of the first container 1002 is avoided.

[0101] In some embodiments, one of the first container 1002 and the whipping blade 3001 is provided with a cylinder 1002C, and the other is provided with a slot 3002B. The cylinder 1002C is rotatably fitted in the slot 3002B. For example, as Figure 14 shown, the cylinder 1002C may be cylindrical and may be located inside the first container 1002, and the cylinder 1002C may be provided at the central position of the bottom of the first container 1002. The slot 3002B may be provided at the bottom of the mounting shaft 3002 of the whipping assembly 3000.

[0102] When installing the whipping assembly 3000, the cylinder 1002C can be inserted into the slot 3002B at the bottom of the mounting shaft 3002, and the top of the mounting shaft 3002 can be inserted and non-rotatably assembled with the sun gear 2003B, so as to realize the fixed limit of the upper and lower ends of the whipping assembly 3000, ensuring the structural stability of the installation of the whipping assembly 3000.

[0103] In some embodiments, as Figure 12 shown, the main machine 1000 may further include a bottom cover 1006 and a temperature sensor 1008. The temperature sensor 1008 may specifically be an NTC and can monitor the temperature of the heating medium in the second container 1003. The bottom cover 1006 can be detachably installed at the bottom of the main machine housing 1001. The heating assembly 1009 and the temperature sensor 1008 can both be installed on the bottom cover 1006 and be located between the bottom cover 1006 and the second container 1003, facilitating the installation and maintenance of the heating assembly 1009 and the temperature sensor 1008.

[0104] The following describes the specific operation method of the cooking machine according to the embodiments of the present invention.

[0105] When in use, as Figure 15 shown, the assembly of the main body 1000 and the whipping assembly 3000 can be completed first, and then the food ingredients can be placed into the first container 1002, and an appropriate amount of tap water can be poured into the second container 1003. Then the machine head 2000 can be assembled with the main body 1000. After the assembly, the machine head 2000 can also be assembled with the whipping assembly 3000 at the same time.

[0106] Then, the power is turned on, and the driving motor 2002 can drive the whipping assembly 3000 to rotate, so as to realize the crushing of the food ingredients in the first container 1002. At the same time, the heating assembly 1009 can heat the water in the second container 1003, and the steam generated after heating and the heated water can be used to heat and steam the food ingredients in the first container 1002, so as to realize the cooking of the food ingredients.
