Description

Technical Field

[0001] This application relates to the field of food processing, and more particularly to a motor assembly and a food processor. Background Technology

[0002] With the continuous improvement of people's living standards, many different types of food processors have appeared on the market. The functions of food processors mainly include, but are not limited to, making soy milk, juicing, rice paste, mincing meat, shaved ice, making coffee, and / or preparing face masks. Food processors can include soy milk makers, blenders, or high-speed blenders—machines that pulverize and mix food. Existing food processors suffer from problems such as high noise levels and long processing times. Utility Model Content

[0003] This application provides a motor assembly and a food processor that operate with low noise and higher pulping efficiency.

[0004] This application provides a motor assembly. The motor assembly includes: a motor stator, configured in an annular shape, the motor stator including a stator support and a coil assembly disposed on the stator support; a motor rotor, rotatably disposed inside the motor stator, the motor rotor including an annular moving grinding head and magnetic poles disposed on the moving grinding head, the magnetic poles corresponding to the coil assembly; and a stationary grinding head, disposed inside the moving grinding head, the stationary grinding head cooperating with the moving grinding head for grinding. When the motor assembly is started, the coil assembly is energized, and the magnetic force between the coil assembly and the magnetic poles causes the motor rotor to rotate relative to the motor stator. At this time, the stationary grinding head and the moving grinding head cooperate to grind and pulverize the food. Grinding and pulverizing food using the motor assembly can effectively reduce noise and achieve high pulverization efficiency.

[0005] Furthermore, the stator support is provided with a limiting groove, and the coil assembly is disposed within the limiting groove. In this way, the coil assembly can be easily and reliably assembled onto the stator support.

[0006] Furthermore, the outer surface of the moving grinding head is provided with a groove, and the magnetic pole is disposed within the groove. In this way, the magnetic pole and the moving grinding head are assembled into one unit, thereby forming a motor rotor.

[0007] Furthermore, a first bearing and a second bearing are provided between the stator support and the moving grinding head, and the first bearing and the second bearing are spaced apart in the vertical direction. This allows the motor rotor to be rotatably mounted inside the motor stator, while maintaining a stable and reliable structure.

[0008] Furthermore, the gap between the stationary grinding head and the moving grinding head ranges from 0.1 mm to 1.5 mm. Thus, the stationary and moving grinding heads work together to pulverize food ingredients.

[0009] Furthermore, the gap between the stationary grinding head and the moving grinding head ranges from 0.1 mm to 0.5 mm. This allows the stationary and moving grinding heads to work together to pulverize food ingredients more finely.

[0010] Furthermore, the rotational speed of the motor rotor is between 100 rpm and 1000 rpm. This allows for low-speed grinding of food with low noise.

[0011] Furthermore, the rotational speed of the motor rotor is between 200 rpm and 500 rpm. This results in lower noise levels when grinding food.

[0012] This application provides a food processor. The food processor includes: a base, comprising a base and a support extending upward from the base; a blending cup assembly assembled on the base; and a lid assembly assembled on the support and located above the blending cup assembly. The lid assembly includes a lid and a motor assembly as described above, the motor assembly being disposed within the lid, and the lid having a discharge port located below the motor assembly. The motor assembly can start at a low speed, efficiently grinding ingredients, resulting in low noise during operation. Because the motor assembly has high grinding efficiency, the food processor's efficiency is improved. Furthermore, since the motor assembly only needs to rotate for a short time to complete the pulverization, its service life is extended. Additionally, by pulverizing ingredients through the motor assembly located in the lid, there is no need for a blade inside the blending cup assembly, facilitating cleaning and reducing the risk of injury to the user's hands during cleaning.

[0013] Furthermore, the machine cover is provided with a positioning shaft, and the stationary grinding head is positioned in conjunction with the positioning shaft. In this way, the stationary grinding head can be easily installed on the positioning shaft, and it can also be easily removed from the positioning shaft.

[0014] Furthermore, the machine cover includes a cover body and an upper cover disposed on the cover body, and the material discharge port is disposed on the cover body. Thus, the machine cover assembly is easy to assemble.

[0015] Furthermore, the cover assembly also includes a discharge baffle disposed on the cover. The discharge baffle closes the discharge port in a first position and opens the discharge port in a second position. By providing the discharge baffle, steam generated inside the mixing cup assembly can be prevented from entering the motor assembly.

[0016] Furthermore, the cover assembly also includes a material discharge motor disposed within the cover, and the material discharge baffle switches between a first position and a second position under the drive of the material discharge motor. By incorporating the material discharge motor, the material discharge baffle can be automatically controlled to open and close the material discharge port, eliminating the need for manual operation and making it more convenient to use.

[0017] Furthermore, the mixing cup assembly includes a mixing cup and a lid covering the mixing cup. The lid includes a discharge hole corresponding to the discharge port and a first sealing ring disposed at the discharge hole. The first sealing ring forms a seal between the lid and the machine cover. Thus, after the food is pulverized by the motor assembly, it falls sequentially into the mixing cup through the discharge port of the machine cover and the discharge hole of the lid. The first sealing ring prevents steam generated inside the mixing cup from flowing between the machine cover and the lid.

[0018] Furthermore, the mixing cup assembly includes a mixing cup and a lid covering the mixing cup. The lid has a venting channel, and the lid includes a vent hole corresponding to the venting channel and a second sealing ring disposed at the vent hole. The second sealing ring forms a seal between the lid and the lid. Thus, venting is achieved through the cooperation of the vent hole and the venting channel, and the second sealing ring prevents steam generated inside the mixing cup from flowing between the lid and the lid.

[0019] Furthermore, the cover assembly also includes a storage box disposed above the motor assembly, with a gap between the stationary grinding head and the moving grinding head for accommodating food ingredients, and the cavity of the storage box communicating with the gap. Thus, the food ingredients in the storage box gradually and automatically fall between the stationary and moving grinding heads, and after being pulverized by the stationary and moving grinding heads, they fall into the cavity of the mixing cup assembly.

[0020] Furthermore, the support base includes a first coupler, and the stirring cup assembly includes a second coupler, with the first coupler and the second coupler docking horizontally. By pushing the stirring cup assembly horizontally onto the base, the first coupler and the second coupler can dock, thereby assembling the stirring cup assembly onto the base.

[0021] Furthermore, the food processor also includes a water tank, pipes, and a pump. The water tank is installed on the base, the pipes connect the water tank and the cavity of the blending cup assembly, and the pump is located in the pipes, used to pump water from the water tank into the cavity of the blending cup assembly through the pipes. By incorporating the water tank, pipes, and pump, automatic water addition to the cavity of the blending cup assembly can be achieved, eliminating the need for manual water addition and making it more convenient to use.

[0022] Furthermore, the food processor also includes an instant heating module disposed within the pipe. During the process of pumping water from the water tank into the cavity of the mixing cup assembly, the water is heated via the instant heating module, resulting in higher heating efficiency.

[0023] Furthermore, the mixing cup assembly includes a mixing cup, a base disposed at the bottom of the mixing cup, a stirring element disposed on the base, and a drive device for driving the stirring element to rotate. By using the stirring element to stir the ingredients in the mixing cup, the scorching of the ingredients during cooking is prevented.

[0024] This application provides another food processor. The food processor includes a blending cup assembly, comprising a blending cup, a base, and a motor assembly as described above, wherein the base is disposed at the bottom of the blending cup, and the motor assembly is disposed on the base.

[0025] Furthermore, the chassis is provided with a positioning shaft, and the stationary grinding head is detachably assembled to the positioning shaft. This allows the stationary grinding head to be easily installed on and easily removed from the positioning shaft.

[0026] Furthermore, the positioning shaft sleeve is provided with a limiting sleeve, which elastically presses against the stationary grinding head. By providing the limiting sleeve, the stationary grinding head can be better confined to the positioning shaft, preventing it from falling off the positioning shaft during pulping.

[0027] Furthermore, a handle is provided at the top of the stationary grinding head. This allows the user to easily remove the stationary grinding head from the positioning shaft using the handle.

[0028] Furthermore, the moving grinding head includes a first part and a second part extending upward from the first part. An inlet for food ingredients is provided between the first part and the base. The inner side of the first part has spirally extending ribs, and the inner side of the second part has grinding teeth. The stationary grinding head includes stationary grinding teeth corresponding to the ribs and grinding teeth. After the food processor starts working, the food ingredients enter from the inlet between the first part and the stationary grinding head, and move upward under the action of the spiral ribs to the space between the second part and the stationary grinding head. The food ingredients are ground between the second part and the stationary grinding head, thus achieving high grinding efficiency and good results.

[0029] Furthermore, the first part gradually tilts outward from top to bottom. In this way, the food is gradually ground by the first part and the stationary grinding head as it moves from bottom to top, achieving preliminary pulverization of the food, which is beneficial for the food to enter the space between the second part and the stationary grinding head for further grinding and pulverization.

[0033] This application provides a motor assembly 40 for use in a food processor 100. See also... Figures 1 to 8 The motor assembly 40 includes a motor stator 10, a motor rotor 20, and a stationary grinding head 30.

[0034] The motor stator 10 is ring-shaped and includes a stator support 11 and a coil assembly 12 disposed on the stator support 11. The motor rotor 20 is rotatably disposed inside the motor stator 10. The motor rotor 20 includes a ring-shaped moving grinding head 21 and magnetic poles 22 disposed on the moving grinding head 21, the magnetic poles 22 corresponding to the coil assembly 12. A stationary grinding head 30 is disposed inside the moving grinding head 21, and the stationary grinding head 30 cooperates with the moving grinding head 21 for grinding. The coil assembly 12 includes a coil support 121 and coil windings 122 disposed on the coil support 121. In the illustrated embodiment, the magnetic poles 22 are permanent magnets. In other embodiments, the magnetic poles 22 can be made of magnetizable materials such as metallic iron or soft magnetic steel.

[0035] When the motor assembly 40 is started, the coil assembly 12 is energized. The magnetic force between the coil assembly 12 and the magnetic pole 22 causes the motor rotor 20 to rotate relative to the motor stator 10. At this time, the stationary grinding head 30 and the moving grinding head 21 work together to grind and pulverize the food. The food processor 100 grinds and pulverizes the food through the motor assembly 40, which can effectively reduce noise and has high pulverization efficiency.

[0036] The stator support 11 is provided with a limiting groove 111, and the coil assembly 12 is disposed within the limiting groove 111. Thus, the coil assembly 12 can be easily and reliably assembled onto the stator support 11. In the illustrated embodiment, the limiting groove 111 is recessed downwards on the top surface of the stator support 11. The stator support 11 can be made of plastic, but is not limited to this.

[0037] The outer surface of the moving grinding head 21 is provided with a groove 219, and the magnetic pole 22 is disposed in the groove 219. In this way, the magnetic pole 22 and the moving grinding head 21 are assembled into one unit, thereby forming the motor rotor 20.

[0038] A first bearing 19 and a second bearing 18 are provided between the stator support 11 and the moving grinding head 21, and the first bearing 19 and the second bearing 18 are spaced apart in the vertical direction. In this way, the motor rotor 20 is rotatably mounted inside the motor stator 10, and the structure is stable and reliable.

[0039] The gap between the stationary grinding head 30 and the moving grinding head 21 ranges from 0.1 mm to 1.5 mm. Thus, the stationary grinding head 30 and the moving grinding head 21 work together to pulverize food ingredients.

[0040] In some embodiments, the gap between the stationary grinding head 30 and the moving grinding head 21 can be 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, 1.5 mm, or any value between any two adjacent of the above.

[0041] Preferably, the gap between the stationary grinding head 30 and the moving grinding head 21 is between 0.1 mm and 0.5 mm. This allows the stationary grinding head 30 and the moving grinding head 21 to work together to pulverize food more finely.

[0042] The rotational speed of the motor rotor 20 is between 100 rpm and 1000 rpm. This allows for low-speed grinding of ingredients with low noise.

[0043] In some embodiments, the rotational speed of the motor rotor 20 can be 100 rpm, 200 rpm, 300 rpm, 400 rpm, 500 rpm, 600 rpm, 700 rpm, 800 rpm, 900 rpm, 1000 rpm, or any value between any two of the above.

[0044] Preferably, the rotational speed of the motor rotor 20 is between 200 rpm and 500 rpm. This results in lower noise levels when grinding food.

[0045] This application provides a food processor 100; please refer to [link / reference]. Figures 1 to 8 In this embodiment, the food processor 100 is a frame-type food processor, which includes a base 50, a mixing cup assembly 60, and a lid assembly 70.

[0046] The base 50 includes a base 51 and a support 52 extending upward from the base 51. A mixing cup assembly 60 is assembled to the base 51. A lid assembly 70 is assembled to the support 52 and located above the mixing cup assembly 60; in the illustrated embodiment, the lid assembly 70 is fixed to the support 52.

[0047] The cover assembly 70 includes a cover 71 and a motor assembly 40. The motor assembly 40 is disposed inside the cover 71, and the cover 71 has a material discharge port 7111 located below the motor assembly 40.

[0048] When the food processor 100 starts working, the motor assembly 40 starts, and the motor rotor 20 begins to rotate, causing the stationary grinding head 30 and the moving grinding head 21 to grind the ingredients. At the same time, the water in the cavity of the blending cup assembly 60 is heated. After the ingredients are ground into powder, they fall into the cavity of the blending cup assembly 60 through the discharge port 7111 and are further heated and cooked until the beverage is ready.

[0049] The motor assembly 40 can start at a low speed to efficiently grind ingredients, resulting in low noise during operation of the food processor 100. Because the motor assembly 40 grinds ingredients efficiently, the overall efficiency of the food processor 100 is improved. Furthermore, since the motor assembly 40 only needs to rotate for a short time to pulverize the ingredients, its lifespan is extended. Additionally, by using the motor assembly 40 located on the lid 71 to pulverize ingredients, there is no need for a blade inside the blending cup assembly 60, making cleaning of the blending cup assembly 60 easier and reducing the risk of injury to the user's hands during cleaning.

[0050] The cover 71 is provided with a positioning shaft 710, and the stationary grinding head 30 is positioned in conjunction with the positioning shaft 710. This allows the stationary grinding head 30 to be easily installed on and removed from the positioning shaft 710. In the illustrated embodiment, the positioning shaft 710 has a flat portion (not shown), and the stationary grinding head 30 has a flat portion hole that corresponds to the flat portion, thus preventing the stationary grinding head 30 from rotating relative to the positioning shaft 710. The stationary grinding head 30 is fixed to the positioning shaft 710 by fasteners or other means.

[0051] The machine cover 71 includes a cover body 711 and an upper cover 712 covering the cover body 711, with the material discharge port 7111 located on the cover body 711. The motor assembly 40 is first assembled onto the cover body 711, and then the upper cover 712 is placed on the cover body 711, thus making the assembly of the machine cover assembly 70 convenient.

[0052] In the illustrated embodiment, the positioning shaft 710 is disposed on the cover body 711. In another embodiment, the positioning shaft 710 is disposed on the upper cover 712.

[0053] The cover assembly 70 also includes a discharge baffle 73 disposed on the cover 71. The discharge baffle 73 closes the discharge port 7111 in a first position and opens the discharge port 7111 in a second position. By providing the discharge baffle 73, steam generated inside the mixing cup assembly 60 can be prevented from entering the motor assembly 40. In one embodiment, the discharge baffle 73 is switched between the first and second positions manually. In another embodiment, the discharge baffle 73 is switched between the first and second positions by a drive device such as a motor.

[0054] In the illustrated embodiment, the cover assembly 70 further includes a material discharge motor 72 disposed within the cover 71. The material discharge baffle 73 switches between a first position and a second position under the drive of the material discharge motor 72. By providing the material discharge motor 72, the material discharge baffle 73 can be automatically controlled to open and close the material discharge port 7111, eliminating the need for manual operation and making it more convenient to use. The material discharge motor 72 can be fixed to the cover body 711 by fasteners, clips, or other means.

[0055] The mixing cup assembly 60 includes a mixing cup 61 and a lid 62 covering the mixing cup 61. The lid 62 includes a discharge hole 621 corresponding to the discharge port 7111 and a first sealing ring 622 disposed at the discharge hole 621. The first sealing ring 622 forms a seal between the lid 62 and the machine cover 71. Thus, after the food is pulverized by the motor assembly 40, it falls sequentially into the mixing cup 61 through the discharge port 7111 of the machine cover 71 and the discharge hole 621 of the lid 62. Furthermore, the first sealing ring 622 prevents steam generated inside the mixing cup 61 from flowing between the machine cover 71 and the lid 62.

[0056] The mixing cup assembly 60 includes a mixing cup 61 and a lid 62 covering the mixing cup 61. The lid 71 has a venting channel 713. The lid 62 includes a vent hole 623 corresponding to the venting channel 713 and a second sealing ring 624 disposed at the vent hole 623. The second sealing ring 624 forms a seal between the lid 62 and the lid 71. Thus, venting is achieved through the cooperation of the vent hole 623 and the venting channel 713, and the second sealing ring 624 prevents steam generated inside the mixing cup 61 from flowing between the lid 71 and the lid 62.

[0057] In the illustrated embodiment, the mixing cup 61 includes a cup body 611, a cup base 612, a base 65, a locking seat 613, and a handle 614. A shock-absorbing pad 619 is provided between the handle 614 and the cup body 611. The handle 614 includes a handle body 6141 and a handle cover 6142 fixed to the handle body 6141. The locking seat 613 engages with the cup body 611 via a snap-fit ​​structure to clamp and fix the base 65. The base 65 is provided with a heating element (not shown) to heat the food inside the mixing cup 61. A base sealing ring 66 forms a seal between the base 65 and the cup body 611. A cup base sealing ring 67 forms a seal between the cup body 611 and the cup base 612.

[0058] The cover assembly 70 also includes a storage box 74 disposed above the motor assembly. A gap 39 for accommodating food is provided between the stationary grinding head 30 and the moving grinding head 21. The cavity 741 of the storage box 74 communicates with the gap 39. Thus, the food in the storage box 74 gradually and automatically falls between the stationary grinding head 30 and the moving grinding head 21. After being pulverized by the stationary grinding head 30 and the moving grinding head 21, the food falls into the cavity of the mixing cup assembly 60. The storage box 74 is assembled onto the upper cover 712. The storage box 74 includes a box body 741 and a lid 742 covering the box body 741. In use, the lid 742 is first removed from the box body 741, the food is placed into the box body 741, and then the lid 742 is placed back onto the box body 741.

[0059] The support base 52 includes a first coupler 521, and the stirring cup assembly 60 includes a second coupler 63. The first coupler 521 and the second coupler 63 are connected horizontally. By pushing the stirring cup assembly 60 horizontally onto the base 51, the first coupler 521 and the second coupler 63 are connected, thereby assembling the stirring cup assembly 60 onto the base 50. In this way, the cover assembly 40 can be fixed to the support base 52 without disassembling the cover assembly 40, making the stirring cup assembly 60 assembled onto the base 50 more convenient.

[0060] Please see Figure 13 The food processor 100 also includes a water tank 81, a pipe 82, and a pump 83. The water tank 81 is installed on the base 50. The pipe 82 connects the water tank 81 and the cavity of the mixing cup assembly 60. The pump 83 is located on the pipe 82 and is used to pump water from the water tank 81 into the cavity of the mixing cup assembly 60 through the pipe 82. By including the water tank 81, the pipe 82, and the pump 83, water can be automatically added to the cavity of the mixing cup assembly 60, eliminating the need for manual water addition and making it more convenient to use.

[0061] The food processor 100 also includes an instant heating module 84 disposed within the pipe 82. During the process of pumping water from the water tank 81 into the cavity of the mixing cup assembly 60, the water is heated by the instant heating module 84, resulting in higher heating efficiency.

[0062] Please see Figure 14 In this embodiment, the mixing cup assembly 60 includes a mixing cup 61, a base 65 disposed at the bottom of the mixing cup 61, a stirring element 66 disposed on the base 65, and a drive device 67 for driving the stirring element 66 to rotate. By using the stirring element 66 to stir the food in the mixing cup 61, the food is prevented from sticking to the bottom during cooking. In one embodiment, the drive device 67 is a motor, but is not limited thereto.

[0063] This application provides another food processor 100; please refer to [link / reference]. Figures 9 to 12 The food processor 100 includes a blending cup assembly 60, which includes a blending cup 61, a base 65, and a motor assembly 40. The base 65 is disposed at the bottom of the blending cup 61, and the motor assembly 40 is disposed at the base 65. In the illustrated embodiment, the food processor 100 also includes a base 50, which houses a power board 55. A control board (not shown) may be disposed in the blending cup 61 or within the base 50. In other embodiments, the food processor 100 may not include a base 50, and both the power board 55 and the control board may be disposed in the blending cup 61.

[0064] The chassis 65 is provided with a positioning shaft 710, and the stationary grinding head 30 is detachably assembled to the positioning shaft 710. In this way, the stationary grinding head 30 can be easily installed on the positioning shaft 710 and can also be easily removed from the positioning shaft 710.

[0065] The positioning shaft 710 is fitted with a limiting sleeve 719, which elastically presses against the stationary grinding head 30. By providing the limiting sleeve 719, the stationary grinding head 30 can be effectively confined to the positioning shaft 710, preventing the stationary grinding head 30 from falling off the positioning shaft 710 during slurry pouring. The limiting sleeve 719 is made of materials including rubber, silicone, etc., and is not limited to these. In the illustrated embodiment, the positioning shaft 710 has a recess (not shown), and the limiting sleeve 719 is positioned by placing it within the recess.

[0066] In the illustrated embodiment, the stationary grinding head 30 is provided with a handle 38 at its top. This allows the user to easily remove the stationary grinding head 30 from the positioning shaft 710 using the handle 38.

[0067] The moving grinding head 21 includes a first part 211 and a second part 212 extending upward from the first part 211. An inlet 2113 for food ingredients is provided between the first part 211 and the base 65. The inner side of the first part 211 has spirally extending ribs 2111, and the inner side of the second part 212 has grinding teeth 2121. The stationary grinding head 30 includes stationary grinding teeth 37 corresponding to the ribs 2111 and the grinding teeth 2121. After the food processor 100 starts working, the food ingredients enter from the inlet 2113 between the first part 211 and the stationary grinding head 30, and move upward under the action of the spiral ribs 2111 to the space between the second part 212 and the stationary grinding head 30. The food ingredients are ground between the second part 212 and the stationary grinding head 30, resulting in high grinding efficiency and good effect.

[0068] In this embodiment, the stator support 11 includes a support body 119 and a positioning post 118 protruding downward from the support body 119. The positioning post 118 is fixed to the chassis 65, thereby fixing the motor stator 10 to the chassis 65. Thus, there is a gap 117 between the support body 119 and the chassis 65, and the food in the mixing cup 61 enters between the moving grinding head 21 and the stationary grinding head 30 through the gap 117 and the inlet 2113 in sequence.

[0069] The first part 211 gradually tilts outward from top to bottom. In this way, the food is gradually ground by the first part 211 and the stationary grinding head 30 as it moves from bottom to top, achieving preliminary crushing of the food, which is conducive to the food entering the second part 212 and the stationary grinding head 30 for further grinding and crushing.

[0070] Preferably, the angle at which the first portion 211 tilts outward from top to bottom is between 10 degrees and 60 degrees.

[0071] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
