Blender cup assembly and food processor

Abstract

The application provides a stirring cup assembly and a food processor. The stirring cup assembly comprises a stirring cup including a cup body and a cup seat, and a motor assembly arranged in the cup seat, the motor assembly including a motor and a motor cover, the motor including a motor body, a motor shaft and a fan blade arranged at the bottom end of the motor shaft, the motor cover including a cover wall surrounding the motor body, the fan blade extending downward beyond the cover wall, the cover wall extending vertically along the up-down direction, and the top end of the cover wall being provided with a wind hole. Since the fan blade extends downward beyond the cover wall, part of the wind generated by the rotation of the fan blade blows upward toward the motor body and is discharged through the wind hole, and the other part blows out from below the cover wall, thereby achieving the cooling of the motor. Since the cover wall extends vertically along the up-down direction, the sound amplification effect generated when the wind flows in the cover wall can be well avoided, thereby effectively reducing the wind noise.

Description

Technical Field

[0001] This application relates to the field of food processing, and more particularly to a blending cup 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 high fan noise. Utility Model Content

[0003] This application provides a mixing cup assembly and a food processor that can effectively reduce wind noise.

[0004] This application provides a stirring cup assembly. The stirring cup assembly includes: a stirring cup, comprising a cup body and a cup base; and a motor assembly disposed within the cup base. The motor assembly includes a motor and a motor cover. The motor includes a motor body, a motor shaft, and a fan blade disposed at the bottom end of the motor shaft. The motor cover includes a cover wall surrounding the motor body, with the fan blade extending downwards from the cover wall. The cover wall extends vertically in the vertical direction, and a vent is provided at the top of the cover wall. Because the fan blade extends downwards from the cover wall, part of the air generated by the rotation of the fan blade blows upwards towards the motor body and is discharged through the vent, thereby cooling the motor. Furthermore, because the cover wall extends vertically in the vertical direction, it effectively prevents the airflow within the cover wall from amplifying noise, thus effectively reducing wind noise.

[0005] Furthermore, the cover wall and the fan blades are spaced apart vertically, with the distance not exceeding 30 millimeters. This allows the lateral wind generated when the fan blades rotate to escape from below the cover wall, thereby reducing noise from wind impacting the cover wall.

[0006] Furthermore, the vertical distance between the cover and the fan blades is between 3 mm and 10 mm. This ensures that a portion of the airflow generated by the fan blades exchanges heat effectively with the motor inside the cover, while also reducing wind noise.

[0007] Furthermore, the cup holder is also equipped with sound-absorbing cotton, which is located between the side wall of the cup holder and the motor cover, and an air duct is provided between the sound-absorbing cotton and the motor cover. In this way, the air discharged from the air hole to the motor cover flows downward through the air duct and re-enters the motor cover from the bottom of the cover wall, thereby creating a circulating airflow for heat dissipation and achieving rapid heat dissipation; in addition, the sound-absorbing cotton also helps to reduce wind noise.

[0008] Furthermore, the top of the sound-absorbing cotton is higher than the air vent, and the bottom of the sound-absorbing cotton is lower than the fan blade. In this way, the wind noise generated by the air coming out of the air vent and the air coming out of the bottom of the cover can be absorbed by the sound-absorbing cotton, thereby effectively reducing noise.

[0009] Furthermore, the top of the sound-absorbing cotton extends 2 to 10 millimeters above the air vent; and / or, the bottom of the sound-absorbing cotton extends 2 to 10 millimeters below the fan blade. Thus, by using the sound-absorbing cotton, noise reduction can be effectively achieved.

[0010] Furthermore, the thickness of the sound-absorbing cotton ranges from 2 mm to 15 mm. In this way, the sound-absorbing cotton does not take up too much space while achieving a good noise reduction effect.

[0011] Furthermore, the thickness of the sound-absorbing cotton ranges from 4 mm to 8 mm. Thus, only a suitable amount of sound-absorbing cotton is needed to achieve a good noise reduction effect.

[0012] Furthermore, the fan blade includes a base plate and a plurality of blades extending upward from the base plate, the blades being arranged circumferentially along the base plate. Thus, the airflow generated when the fan blade rotates blows laterally or upward, resulting in good heat dissipation.

[0013] Furthermore, a base plate is provided at the bottom of the cup body, and the motor is fixed to the base plate. The motor cover and the cup body cooperate to clamp and fix the base plate. This makes the assembly of the stirring cup assembly more convenient and reliable.

[0014] This application provides a food processor. The food processor includes: a base; and a mixing cup assembly as described above, assembled on the base. Attached Figure Description

[0018] Please see Figures 1 to 6 The food processor 100 can be used to make soy milk, rice paste, juice, etc. The food processor 100 includes a base 50 and a blending cup assembly 60, which is assembled onto the base 50. The base 50 includes a housing (not shown) and a control circuit board (not shown) disposed within the housing. The food processor 100 also includes a soundproof cover 70 that encloses the blending cup assembly 60.

[0019] The mixing cup assembly 60 includes a mixing cup 10 and a motor assembly 20. The mixing cup 10 includes a cup body 11 and a cup base 12. The motor assembly 20 is disposed within the cup base 12. The motor assembly 20 includes a motor 21 and a motor cover 22. The motor 21 includes a motor body 211, a motor shaft 214, and a fan blade 212 disposed at the bottom end of the motor shaft 214. The motor cover 22 includes a cover wall 221 surrounding the motor body 211. The fan blade 212 extends downward from the cover wall 221. The cover wall 221 extends vertically in the up-down direction, and a vent 222 is provided at the top of the cover wall 221.

[0020] Because the fan blade 212 extends downwards from the cover wall 221, part of the air generated by the rotation of the fan blade 212 blows upwards towards the motor body 211 and is discharged through the air hole 222, thereby cooling the motor 21. Since the cover wall 221 extends vertically in the vertical direction, it effectively avoids the amplification effect of airflow within the cover wall 221, thus effectively reducing wind noise. The cover wall 221 and the fan blade 212 have a vertical distance L1, which is no greater than 30 mm. Thus, the lateral airflow generated when the fan blade 212 rotates can be discharged from below the cover wall 221, thereby reducing the noise generated by wind impacting the cover wall 221.

[0021] The vertical distance A between the cover wall 221 and the fan blade 212 is between 3 mm and 10 mm. This ensures that a portion of the air generated by the fan blade 212 can exchange heat effectively with the motor 21 inside the cover wall 221, while also reducing wind noise.

[0022] In some embodiments, the vertical distance A between the cover wall 221 and the fan blade 212 can be 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, or any value between any two adjacent ones mentioned above.

[0023] The cup holder 12 is also equipped with sound-absorbing cotton 30, which is located between the side wall of the cup holder 12 and the motor cover 22, and an air duct 35 is provided between the sound-absorbing cotton 30 and the motor cover 22. In this way, the air discharged from the air hole 222 into the motor cover 22 flows downward through the air duct 35 and re-enters the motor cover 22 from the bottom of the cover wall 221, thereby forming a circulating airflow for heat dissipation and achieving rapid heat dissipation; in addition, the sound-absorbing cotton 30 can also reduce wind noise.

[0024] The top of the sound-absorbing cotton 30 is higher than the air vent 222, and the bottom of the sound-absorbing cotton 30 is lower than the fan blade 212. In this way, the wind noise generated by the wind coming out of the air vent 222 and the wind coming out of the bottom of the cover wall 221 can be absorbed by the sound-absorbing cotton 30, thereby effectively reducing noise.

[0025] The top of the sound-absorbing cotton 30 extends beyond the air vent 222 by a length L2 ranging from 2 mm to 10 mm; and / or, the bottom of the sound-absorbing cotton 30 is lower than the fan blade 212 by a length L1 ranging from 2 mm to 10 mm. Thus, by configuring the sound-absorbing cotton 30, noise reduction can be effectively achieved.

[0026] In some embodiments, the length L2 of the top of the sound-absorbing cotton 30 extending above the air vent 222 can be 2 mm, 4 mm, 6 mm, 8 mm, 10 mm, or any value between any two adjacent values. The length of the bottom of the sound-absorbing cotton 30 below the fan blade 212 can be 2 mm, 4 mm, 6 mm, 8 mm, 10 mm, or any value between any two adjacent values.

[0027] The thickness of the sound-absorbing cotton 30 ranges from 2 mm to 15 mm. In this way, the sound-absorbing cotton 30 does not take up too much space while achieving a good noise reduction effect.

[0028] In some embodiments, the thickness of the sound-absorbing cotton 30 can be 2 mm, 4 mm, 6 mm, 8 mm, 10 mm, 12 mm, 14 mm, 15 mm, or any value between any two adjacent values ​​mentioned above.

[0029] The thickness of the sound-absorbing cotton 30 ranges from 4 mm to 8 mm. Therefore, only an appropriate amount of sound-absorbing cotton 30 is needed to achieve a good noise reduction effect.

[0030] The fan blade 212 includes a base plate 2121 and a plurality of blades 2122 extending upward from the base plate 2121, wherein the plurality of blades 2122 are arranged circumferentially along the base plate 2121. In this way, the wind generated when the fan blade 212 rotates will blow to the side or upward, resulting in good heat dissipation.

[0031] The bottom of the cup body 11 is provided with a base 24, and the motor 21 is fixed to the base 24. The motor cover 22 and the cup body 11 cooperate to clamp and fix the base 24. During assembly, the motor 21 is first fixed to the base 24, and then the base is clamped and fixed by assembling the motor cover 22 and the cup body 11. This makes the assembly of the stirring cup assembly more convenient and reliable. In the illustrated embodiment, the motor cover 22 and the cup body 11 are clamped and fixed by a screw fastener. In other embodiments, the motor cover 22 and the cup body 11 can also be coupled in other ways, which are not limited here. A sealing ring 29 is also provided between the base 24 and the cup body 11.

[0032] The motor shaft 214 of the motor 21 passes through the chassis 24, and a stirring blade 213 is provided at the top of the motor shaft 214. The chassis 24 is also provided with a heating tube 241. The stirring blade 213 is used to stir and crush the ingredients in the stirring cup 10, and the heating tube 241 is used to heat the ingredients in the stirring cup 10.

[0033] 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.
