The following disclosure provides many different embodiments or examples for implementing different structures of the present application. In order to simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit this application. In addition, the present application may repeat reference numerals and / or reference letters in different examples. Such repetition is for simplicity and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present application provides examples of various specific processes and materials, but those of ordinary skill in the art may be aware of the application of other processes and / or the use of other materials.

Please refer to FIG. 1, the present application discloses a food processor 300. The food processor 300 may be a wall breaker, a juicer, a soybean milk machine, a grinder, a meat grinder, a shredder, a shredder, a slicer, etc Machine with blades. The food processor 300 of FIG. 1 is a wall breaking machine, which is only one form of the food processor 300 and should not be construed as a limitation of the present application.

Please refer to FIG. 2 together. The food processor 300 according to the embodiment of the present application includes a base 100 and a stirring cup 200. The base 100 is used to support the stirring cup 200. In other words, the stirring cup 200 is provided on the base 100. In this embodiment, the stirring cup 200 is detachably provided on the base 100. The blender 200 is used to hold food. For example, the blender cup 200 can be used to hold foods such as vegetables, beans, or meat.

In this embodiment, the height ratio of the base 100 to the blender cup 200 is less than or equal to 1/2. That is to say, the ratio H1 / H2 of the height H1 of the base 100 to the height H2 of the stirring cup 200 is less than or equal to 1/2. Preferably, the height ratio of the base 100 to the stirring cup 200 is 1 / 5-1 / 2, for example, H1 / H2 is 1/5, 1/4, 1/3, 1/2 and other ratios.

In this way, the height dimension of the base 100 relative to the stirring cup 200 is small, so that the overall size of the food processor 300 is small, which is beneficial to the storage of the food processor 300.

In the related art, the height ratio of the base of the food processor to the blender cup is approximately 1, that is, the height of the base is almost equal to the height of the blender cup, so that the overall volume of the food processor is larger and it is not easy to store and reduce User experience.

It should be noted that the height H1 of the base 100 is the largest dimension in the height direction of the base 100. In other words, the height H1 of the base 100 is the distance between the lowest point and the highest point of the base 100 in the height direction. The height H2 of the jar 200 is the largest dimension in the height direction of the jar 200. In other words, the height H2 of the stirring cup 200 is the distance between the lowest point and the highest point of the stirring cup 200 in the height direction.

In this embodiment, the cross section of the base 100 has a rectangular shape with rounded corners. It should be noted that, in other embodiments, the cross section of the base 100 may have an elliptical shape, a circular shape, a polygonal shape, an irregular shape, and the like.

Please refer to FIGS. 3 to 5. Specifically, the base 100 includes a housing 10 and a motor 20. The motor 20 is provided in the housing 10. The power of the motor 20 is less than 1500W. Further, the power of the motor 20 is 100-1500W. For example, the power of the motor 20 is 100W, 200W, 300W, 500W, 800W, 1000W, 1500W, and so on.

Preferably, the power of the motor 20 is 500-1500W. The height ratio of the housing 10 to the motor 20 is less than or equal to 2. In other words, the ratio H3 / H4 of the height H3 of the housing 10 to the height H4 of the motor 20 is less than or equal to 2. Preferably, the height ratio H3 / H4 of the housing 10 to the motor 20 is 1.1-2. For example, H3 / H4 is a ratio of 1.1, 1.2, 1.3, 1.5, 2 or the like.

It should be noted that the height H3 of the housing 10 is the largest dimension of the housing 10 in the height direction. That is, the height H3 of the housing 10 is the distance between the lowest point and the highest point of the housing 10 in the height direction. Since the motor 20 is disposed in the housing 10, in this embodiment, the height H3 of the housing 10 is equal to the height H1 of the base 100, that is, H3 = H1.

In this way, the height ratio of the housing 10 to the motor 20 is less than or equal to 2, which makes the structure of the base 100 more compact, which is beneficial to reduce the height of the base 100, and the base 100 is thinner, which is beneficial to the storage of the base 100 and the food processor 300.

It can be understood that when H3 / H4 is 1.1-1.2, this means that the height of the housing 10 is almost equal to the height of the motor 20, which makes the cooperation structure of the housing 10 and the motor 20 more compact.

In addition, when the power of the motor 20 is less than 1500W, the power of the motor 20 can meet the requirements of stirring and cutting food. Preferably, the motor 20 may be a brushless DC motor. In this embodiment, the motor 20 can be controlled to operate at different powers according to demand, that is, the power of the motor 20 can be adjusted. For example, when the food processor 300 handles a softer substance, the motor 20 can be controlled to operate at a low power; when the food processor 300 processes a harder substance, the motor 20 can be controlled to operate at a higher power.

Please refer to FIGS. 3 to 5. In this embodiment, the housing 10 may be made of plastic and / or metal. Specifically, the housing 10 includes a bottom cover 11, a surrounding wall 12 and an upper cover 13. The surrounding wall 12 is disposed on the bottom cover 11 and surrounds the motor 20. The upper cover 13 covers the end of the surrounding wall 12 away from the bottom cover 11. In this way, the housing 10 is formed by assembling multiple components, which facilitates the manufacturing of the housing 10.

The bottom cover 11 may be made of plastic. The surrounding wall 12 is substantially cylindrical. The surrounding wall 12 can be made of a metal material. For example, the surrounding wall 12 is made of aluminum alloy, which can improve the heat dissipation efficiency of the surrounding wall 12. The upper cover 13 is covered on the surrounding wall 12. In this way, the upper cover 13 can be used to support the blender cup 200.

In this embodiment, the upper cover 13 is formed with a sink 131, and the bottom of the stirring cup 200 is located in the sink 131. In this way, the setting of the sink 131 allows the stirring cup 200 to be more stably supported on the upper cover 13. In this embodiment, the cross section of the sink 131 is non-circular. For example, the cross section of the sink 131 may have a rounded rectangular shape or a trapezoidal shape.

A coupler 30 is provided in the sink 131, and the coupler 30 is used to transmit electric energy to the stirring cup 200. The upper cover 13 is formed with a drain hole 132 communicating with the sink 131, and the drain hole 132 communicates with the outside of the base 100. In this way, when there is liquid in the base 100, the liquid can be discharged out of the base 100 through the drain hole 132.

Further, the motor 20 is suspended and fixed on the upper cover 13. A gap is formed between the motor 20 and the bottom cover 11. That is to say, the motor 20 is not in contact with the bottom cover 11. In this way, the upper cover 13 can reduce the vibration of the motor 20, so that the noise generated by the food processor 300 can be reduced.

In addition, the motor 20 is suspended on the upper cover 13, and the output shaft 21 of the motor 20 can be shortened, thereby reducing the height of the motor 20, thereby reducing the height of the base 100.

In this embodiment, the output shaft 21 of the motor 20 extends into the sink 131, and the first clutch 40 is fixed to the output shaft 21 of the motor 20, and the first clutch 40 is located in the sink 131. This allows the motor 20 to drive the blender cup 200 to work through the first clutch 40.

In this embodiment, the height H5 between the top surface of the first clutch 40 and the bottom surface of the base 100 is less than or equal to 120 mm. For example, the height H5 between the top surface of the first clutch 40 and the bottom surface of the base 100 is 120 mm, 110 mm, 105 mm, and 100 mm.

6 and 7, in this embodiment, the power of the motor 20 is less than 1500 W, and the radius R of the motor 20 is less than or equal to 50 mm. Preferably, the radius R of the motor 20 is 40-50 mm. For example, the radius R of the motor 20 is 40 mm, 42 mm, 45 mm, and 50 mm.

The motor 20 of this embodiment is customized according to the needs of the miniaturization of the base 100. While satisfying the power requirements, the lateral size of the motor 20 is small, making the size of the base 100 small, which is beneficial to the miniaturization of the base 100.

It should be noted that the radius of the motor 20 refers to the radius of the smallest circle that encloses the transverse dimension of the cell of the motor 20.

Further, the height H4 of the motor 20 is less than or equal to 60 mm. Preferably, the height H4 of the motor 20 is 40-60 mm. For example, the height H4 of the motor 20 is 40 mm, 42 mm, 45 mm, and 60 mm. In the general motor, the height of the motor with a power of 500-1500W is generally greater than 70mm. Therefore, the motor 20 of this embodiment can meet the needs of miniaturization of the base 100, making the base 100 thinner and lighter.

As described above, the height ratio H3 / H4 of the housing 10 to the motor 20 is less than or equal to 2. Therefore, it can be understood that when the height H4 of the motor 20 is 50 mm, the height of the housing 10 is less than or equal to 100 mm. That is to say, in this embodiment, the height H3 of the housing 10 is less than or equal to 100 mm.

It should be noted that, referring to FIG. 5, the motor 20 includes a first bearing housing 25 and a second bearing housing 26 spaced from the first bearing housing 25. The first bearing housing 25 is provided with a first bearing 27 and a second bearing housing 26 A second bearing 28 is provided, and the output shaft 21 of the motor 20 passes through the first bearing 27 and the second bearing 28. The height H4 of the motor 20 is the size between the outer end surface of the first bearing block 25 and the outer end surface of the second bearing block 26.

In this embodiment, the power of the motor 20 is less than 1500W, and the power density of the motor 20 is greater than or equal to 0.8 KW / kg. Preferably, the power density of the motor 20 is 0.8-1.2KW / kg. For example, the power density of the motor 20 is 0.8 KW / kg, 0.9 KW / kg, 1 KW / kg, 1.1 KW / kg, 1.2 KW / kg, and so on.

The power density refers to the ratio of the mass of the motor 20 to the output power of the motor 20. In general, in order to meet the power requirements of the motor, the greater the power of the motor, the more materials required to manufacture the motor, so that the larger the volume of the motor, the greater the heat generated by the motor.

In this embodiment, the power density of the motor 20 is greater than or equal to 0.8 KW / kg, so that the calorific value of the motor 20 is less, and the temperature rise requirement is met. When the power density of the motor 20 is in the above range, the base 100 may omit heat dissipation devices such as fans. That is to say, one end of the motor 20 does not need to be installed to the cooling fan, so that the height of the base 100 can be reduced, which is beneficial to the miniaturization of the base 100.

Further, the temperature rise range of the motor 20 is less than or equal to 120K. The temperature rise refers to the difference between the temperature of the motor 20 and the surrounding air. When the temperature rise of the motor 20 is in the above range, it means that the difference between the temperature of the air in the base 100 and the temperature of the motor 20 is small. There is no need to install a heat dissipation device in the housing 10, and it can also ensure that the temperature of the housing 10 will not burn the user.

In this embodiment, the ratio of the torque of the motor 20 at a low rotation speed to the torque of the motor 20 at a high rotation speed is greater than or equal to 0.7. Preferably, the ratio of the torque of the motor 20 at a low speed to the torque of the motor 20 at a high speed is 0.7-0.9. For example, the ratio of the torque of the motor 20 at a low rotation speed to the torque of the motor 20 at a high rotation speed is 0.7, 0.75, 0.8, 0.85, 0.9, and so on.

Among them, the low speed is less than 200r / min. For example, the low speed is 80r / min, 90r / min, 100r / min, 120r / min, 150r / min, 180r / min, etc.

The high speed is greater than 3000r / min, for example, the high speed is 3100r / min, 3500r / min, 4000r / min, 4500r / min, 5000r / min, 6500r / min, etc.

The torque of the motor 20 at a low rotation speed is greater than or equal to 2.8 N.m. Preferably, the torque range of the motor 20 at a low speed is 2.8-3.2 N.m. For example, the torque of the motor 20 at a low rotation speed is 2.8 N.m, 2.9 N.m, 3.0 N.m, 3.1 N.m, 3.2 N.m and other specific values.

In general, in an AC motor, the torque of the AC motor increases with the increase of the rotation speed, that is, the torque of the AC motor at a low rotation speed is smaller.

As described above, in this embodiment, the motor 20 may use a brushless DC motor. In addition, through a specific design, regardless of whether the motor 20 is at a low speed or a high speed, the motor 20 can still maintain a large torque operation, thereby It can make the motor 20 have a good stirring effect on food even at a low rotation speed.

Please refer to FIGS. 6 and 7. Specifically, the motor 20 includes a stator 22, a rotor 23 and a bracket 24. The stator 22 surrounds the rotor 23. The stator 22 is fixed inside the bracket 24 and fixedly connected to the bracket 24. The rotor 23 includes an output shaft 21 that extends out of the bracket 24.

The bracket 24 is formed with a plurality of lugs 241, and the motor 20 is suspended and fixed on the upper cover 13 through the lugs 241. In this embodiment, the number of lugs 241 is four. In other embodiments, the number of lugs 241 may be two, three, five, etc. greater than one.

In order to increase the heat dissipation speed of the stator 22 and the rotor 23, preferably, the bracket 24 is formed with a plurality of heat dissipation holes 242. It can be understood that the heat generated by the stator 22 and the rotor 23 can be radiated to the outside of the motor 20 through the heat dissipation holes 242.

Please refer to FIG. 5 again. In this embodiment, the base 100 further includes a circuit board 50. The circuit board 50 is accommodated in the housing and located on the side of the motor 20. The circuit board 50 is horizontally disposed. In this way, the horizontal arrangement of the circuit board 50 can make the height of the housing 10 lower, so that the height of the base 100 can be reduced.

The circuit board 50 can be used to control the operation of the motor 20. For example, the circuit board 50 may be used to control the input voltage and / or input current of the motor 20 to control the rotation speed of the motor 20.

In this embodiment, the base 100 further includes a display device 60 that is housed in the housing 10 and the display device 60 is used to display the working state of the food processor 300. For example, the display device 60 may display the power of the motor 20. The display device 60 includes a display element 61, for example, a display lamp and / or a display screen.

Please refer to FIG. 5 and FIG. 8, the stirring cup 200 includes a food cup 210 and a stirring assembly 220. The stirring assembly 220 is provided on the food cup 210. Specifically, the food cup 210 is formed with a receiving space 211. The storage space 211 is used to store food. The food cup 210 includes a cup body 212 and a cup lid 213 that cooperates with the cup body 212.
