Description

Technical Field

[0001] This application relates to the field of small household appliances, and more particularly to a food processor. Background Technology

[0002] As people's living standards continue to improve, many different types of food processors have appeared on the market. The functions of a food processor 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. Currently, some food processors are noisy when blending food, and their large size makes them inconvenient to store. Utility Model Content

[0003] To solve at least one of the above-mentioned technical problems, this application provides a food processor.

[0004] This application provides a food processor, which includes:

[0005] A base, including a base and a support extending upward from the base;

[0006] A stirring cup assembly, detachably assembled to the base, the stirring cup assembly having a cup cavity; and

[0007] The machine cover is assembled on the support base and covers the mixing cup assembly;

[0008] The ratio of the volume inside the cup cavity of the mixing cup assembly to the overall volume of the food processor is greater than or equal to 0.45 and less than or equal to 0.68.

[0009] The above settings optimize the ratio of the volume of the mixing cup assembly's cavity to the overall volume of the food processor, resulting in a more rational spatial layout. This allows for a smaller overall size while still meeting the cavity capacity requirements, making it easier to store. Furthermore, the installation stability of the mixing cup assembly within the food processor is improved, reducing vibration amplitude during blending and mitigating resonance with other components, thereby reducing noise generated during blending.

[0010] Optionally, the orthographic projection of the base in the horizontal plane is square, and the extension directions of two adjacent sides of the square are a first direction and a second direction perpendicular to the horizontal plane. The stirring cup assembly and the support base are arranged in the second direction. The stirring cup assembly includes a stirring cup, which includes a cup body and a handle connected to the cup body. The orthographic projections of the cup body and the cup cavity in the horizontal plane are both square.

[0011] In this way, the mixing cup can be made shorter while maintaining the same volume, and the square cup body can better achieve turbulence when mixing ingredients, which is conducive to better crushing of ingredients.

[0012] Optionally, the length D1 of the orthographic projection of the cup body in the horizontal plane in the first direction, the length L1 in the second direction, and the height H1 of the cup cavity are related to the length D2 of the orthographic projection of the base of the food processor in the horizontal plane in the first direction, the length L2 in the second direction, and the overall height H2 of the food processor by the following formula:

[0013] L2 <L1+70mm;

[0014] H2

[0015] D2 = D1 + d, where d is greater than or equal to 0 and less than or equal to 15 mm.

[0016] The dimensions of the cup body, the base of the food processor, and the overall height of the machine have been optimized. This optimizes the horizontal and vertical dimensions of the cup cavity and the food processor, resulting in a more reasonable ratio between the space for blending ingredients and the overall space of the food processor. The spatial layout of the food processor is more rational, the installation stability of the blending cup component in the whole machine is improved, the noise generated during the use of the food processor is reduced, and the user experience of the food processor is enhanced.

[0017] Optionally, the stirring cup includes a cup base plate disposed at the bottom of the cup body, and the stirring cup assembly also includes a cup lid assembly covering the stirring cup. The cup body, the cup base plate, and the cup lid assembly form the cup cavity, and the height H1 of the cup cavity is the vertical distance between the cup base plate and the cup lid assembly.

[0018] The lid assembly has minimal impact on the internal volume of the cup cavity. This makes it easier to set the size of the cup cavity and simplifies the design process of the blender.

[0019] Optionally, the height H1 of the cup cavity ranges from 120mm to 220mm, and the overall height H2 of the food processor ranges from 260mm to 330mm.

[0020] ​This optimization of the cup height and overall height of the food processor results in a more rational spatial layout. The stability of the mixing cup assembly within the machine is improved, reducing vibration during blending and mitigating resonance with other components, thus lowering noise levels. Furthermore, the optimized cup height enhances the flow of food within the cup, improving circulation, reducing the risk of the blades running idle, and allowing for better contact between the food and blades. This results in smaller, more refined food particles, improving the texture and flavor of the processed food.

[0021] Optionally, the height H1 of the cup cavity ranges from 155mm to 200mm, and the overall height H2 of the food processor ranges from 265mm to 330mm.

[0022] This helps reduce noise generated during the use of the food processor. It also improves the flow of food within the cup, resulting in smaller, more pulverized particles and thus enhancing the texture of the food processed by the food processor.

[0023] Optionally, the height H1 of the cup cavity ranges from 170mm to 190mm, and the overall height H2 of the food processor ranges from 275mm to 315mm.

[0024] In this way, the above settings better reduce the noise generated by the food processor during use, which is beneficial to the user experience. Furthermore, they improve the flow of food within the cup cavity, significantly reducing the particle size of the pulverized food and thus enhancing the texture of the processed ingredients.

[0025] Optionally, the mixing cup assembly further includes a motor and a blade assembly. The motor is located at the bottom of the mixing cup and includes an output shaft. The blade assembly is located at the top of the output shaft and inside the mixing cup.

[0026] The overall height H2 of the food processor ranges from 275mm to 295mm.

[0027] In this way, the motor's output shaft is directly connected to the blade assembly, forming a direct-drive structure that reduces the height of the food processor. The optimized overall height helps reduce noise in direct-drive food processors and also improves the flow of food within the cup cavity, enhancing food circulation. This results in smaller particle sizes after the food is pulverized, thus improving the texture of the processed food.

[0028] Optionally, the food processor includes a motor disposed within the base, and the blending cup assembly further includes a blade assembly located within the blending cup. When the blending cup assembly is assembled on the base, the blade assembly is connected to the motor.

[0029] The overall height H2 of the food processor ranges from 290mm to 315mm.

[0030] The blade assembly is located inside the mixing cup, while the motor is located on the base, forming a separate structure. The optimized overall height of the machine is more conducive to noise reduction in a separate blender and also to the turbulence effect of the ingredients inside the mixing cup. The ingredients are pulverized into smaller particles, thereby improving the texture of the food processed by the blender.

[0031] Optionally, the length D1 of the orthographic projection of the cup body in the horizontal plane ranges from 100mm to 160mm in the first direction, and the length L1 in the second direction ranges from 100mm to 160mm.

[0032] This facilitates the turbulence of ingredients within the cup cavity, improves ingredient circulation, reduces or avoids dead zones in the mixing process, and ensures that all ingredients within the cup cavity can participate in the mixing process. This results in smaller particle sizes after the ingredients are pulverized, thereby improving the texture of the food processed by the food processor.

[0033] Optionally, the length D2 of the base of the food processor in the horizontal plane in the first direction X ranges from 140mm to 160mm, and the length L2 in the second direction Y ranges from 185mm to 200mm.

[0034] In this way, the food processor's dimensions are well-proportioned, making it more stable when placed on the countertop.

[0035] Optionally, the thickness of the cup body ranges from 5mm to 12mm.

[0036] This design avoids making the mixing cup assembly too heavy and makes it easy to handle.

[0037] Optionally, the volume inside the cup cavity is the product of the length D1 of the orthographic projection of the cup body in the horizontal plane in the first direction, the length L1 in the second direction, and the height H1 of the cup cavity.

[0038] The thickness of the sidewall of the cup body has little impact on the internal volume of the cup cavity. Using the dimensions of the cup body to determine the internal volume of the cup cavity makes it easier to set the dimensions of the cup cavity and the dimensions of the cup body, which facilitates design and manufacturing.

[0039] Optionally, the overall envelope volume of the food processor is the product of the length D2 of the orthographic projection of the base in the horizontal plane in the first direction, the length L2 in the second direction, and the overall height H2 of the food processor.

[0040] This makes it easy to set the size of the food processor cup and the overall size of the machine, facilitating design and manufacturing.

[0041] Optionally, the length D1 of the orthographic projection of the cup body in the horizontal plane in the first direction is less than or equal to the length L1 in the second direction, and the relationship between the height H1 of the cup cavity and the length L1 in the second direction is:

[0042]

[0043] By setting a reasonable cup cavity size relationship, it is beneficial to increase the turbulence effect, reduce the dead corners of mixing, improve the efficiency of food circulation, and optimize the taste of the food processed by the food processor. Moreover, it makes the dimensions of the food processor in the horizontal and vertical directions more coordinated and reasonable, the overall space layout can be optimized, the food processor is more stable, and the noise is less.

The first direction X and the second direction Y are perpendicular in the horizontal plane. Figure 6 , Figure 7 and Figure 9 .

[0061] The food processor of this application will now be described in detail with reference to the accompanying drawings. Unless otherwise specified, the features of the following embodiments and implementation methods can be combined with each other.

[0062] Please see Figures 1 to 5, the cooking machine 100 can be used to make soy milk, rice paste, juice, etc. The cooking machine 100 includes a base 10, a mixing cup assembly 20 and a machine cover 30. In some embodiments, the cooking machine 100 further includes a control component 40.

[0063] The base 10 includes a base 11 and a support base 12 extending upward from the base 11. The support base 12 and the base 11 can be integrally formed or separately formed and then assembled together. The top view of the base 10 can be circular, rectangular (the corners can be rounded), square (the corners can be rounded), polygonal (the corners can be rounded), oval, etc. The top view of the mixing cup assembly 20 can be the same as or different from the shape of the base 10.

[0064] Please refer to Figures 3 to 5 , the mixing cup assembly 20 is assembled on the base 11. The mixing cup assembly 20 includes a mixing cup 21, a heating plate 22 disposed at the bottom of the mixing cup 21, and a knife assembly 23. In other embodiments, the mixing cup assembly 20 includes a mixing cup 21, a chassis disposed at the bottom of the mixing cup 21, and a knife assembly 23. The heating element can be disposed on the base 11, and the heat is conducted from the heating element to the chassis to heat the ingredients in the mixing cup 21. The mixing cup 21 is used to place the ingredients, the heating plate 22 is used to heat the ingredients in the mixing cup 21, and the knife assembly 23 is used to stir and crush the ingredients in the mixing cup 21. Please refer to Figure 3 and Figure 4 , the mixing cup 21 includes a cup body 219 and a handle 218. The cup body 219 is provided with a cup spout 2191, and the cup spout 2191 is disposed opposite to the position of the handle. The support base 12 is provided with a mating groove 127 corresponding to the cup spout 2191, and the cup spout 2191 is located in the mating groove 127. The cross-section of the cup body 219 can be set to be square, that is, the orthographic projection of the cup body 219 in the horizontal plane is square. The mixing cup 21 is a square cup. In this way, the mixing cup 219 can be made shorter and still have the same volume. R corners can be provided at the square corners. Turbulence ribs 214 can be provided at the four corners of the mixing cup 21, or the turbulence ribs 214 can be not provided. In other embodiments, the cross-section of the cup body 219 can also be set to be circular or other shapes.

[0065] The machine cover 30 is assembled on the support base 12, and the machine cover 30 covers the mixing cup assembly 20. The base 10 and the machine cover 30 present a "C" shape, and the three sides wrap the mixing cup assembly 20, reducing the reflected noise outside the base 10 of the noise generated inside the mixing cup assembly 20.

[0066] In some embodiments, the machine cover 30 can be movably covered on the mixing cup assembly 20. In Figure 1 and Figure 2In the illustrated embodiment, the cover 30 is rotatably assembled to the support base 12. In another embodiment, the cover 30 is rotatably assembled to the support base 12 in a horizontal direction. In another embodiment, the cover 30 is detachably assembled to the support base 12. In yet another embodiment, the cover 30 is vertically connected to the support base 12.

[0067] In another embodiment, the cover 30 is fixed to the support base 12, and the stirring cup assembly 20 is pushed into the base 10 from the side or the front.

[0068] In some embodiments, the control component 31 is disposed on the cover 30 and / or the support base 12, and is used to display information, such as function and time, and for user operation, such as selecting a cooking function, starting / pausing the cooking process, etc. In the related "L"-shaped blender, the base protrudes horizontally from the blending cup assembly, and the control component is disposed on the upper surface of the protruding portion. Compared with the related technology, the control component 31 of this application is disposed on the cover 30 and / or the support base 12, and the blender 100 occupies less space in the horizontal direction overall. The "U"-shaped blender 100 further reduces the overall space ratio of the machine; the "U"-shaped blender 100 can be smaller and thinner through a better arrangement of electrical components.

[0069] In the illustrated embodiment, the control component 31 is located on the cover 30, which facilitates user operation, eliminates the need for bending over, and is closer to the user's eyes, making it easier for the user to see the information on the control component 31. A power supply component 13 is housed within the support base 12, and the control component 31 is electrically connected to the power supply component 13. The power supply component 13 is used to connect to an external power source to power the food processor and, consequently, the control component 31. A motor 40 is located within the base 11 or at the bottom of the mixing cup 21. The motor 40 includes a motor shaft 41, and the blade assembly 23 is located at the top of the motor shaft 41. In one embodiment, the motor 40 is a brushless motor without a rear end cover, resulting in a lower motor height and reducing the overall height of the food processor 100. In other embodiments, the motor 40 can also be a conventional brushed motor or a brushless motor.

[0070] Since the power supply component 13 is located inside the support base 12 and the control component 31 is located inside the cover 30, the power supply component 13, the control component 31 and the motor 40 are not stacked together. By reasonably arranging the positions of the three components, the height of the food processor 100 can be effectively reduced, so that the overall height of the food processor 100 is no more than 280 mm, making it more compact and exquisite. In this way, the vibration generated by the food processor 100 during operation can be reduced, and it occupies less space.

[0071] In another embodiment, both the power supply component 13 and the control component 31 are disposed within the cover 30. The power supply component 13 and the control component 31 can be integrated or disposed separately. The motor 40 is disposed within the base 11 or at the bottom of the mixing cup 21, which also reduces the height of the food processor 100. In another embodiment, both the power supply component 13 and the control component 31 are disposed within the support base 12. The power supply component 13 and the control component 31 can be integrated or disposed separately, and the motor 40 is disposed within the base 11 or at the bottom of the mixing cup 21. In another embodiment, the power supply component 13 is disposed within the base 11, the control component 31 is disposed within the support base 12, and the motor 40 is disposed within the base 11 or at the bottom of the mixing cup 21. In another embodiment, the control component 31 can be disposed within the base 11, and the power supply component 13 can be disposed within the base 11, the support base 12, or the cover 30. In yet another embodiment, both the power supply component 13 and the control component 31 are disposed within the cover 30, and the motor 40 is disposed within the cup lid assembly 22 of the mixing cup assembly 20. In another embodiment, the power supply component 13 is disposed within the support base 12, the control component 31 is disposed within the lid 30, and the motor 40 is disposed within the lid assembly 22 of the blending cup assembly 20. In other embodiments, the control component 31 may be disposed within both the lid 30 and the support base 12. The control component 31 may include multiple circuit boards, which, by being distributed, facilitate setup and enable more control functions of the food processor 100.

[0072] In one embodiment, the blade assembly 23 is detachably disposed at the bottom of the mixing cup 21. See also... Figure 5 The motor 40 is located at the bottom of the stirring cup 21, the output shaft 41 of the motor 40 passes through the heating plate 22, and the top of the output shaft 41 is provided with a rotating shaft 48. The blade assembly 23 is detachably assembled to the rotating shaft 48.

[0073] Please see Figures 6 to 9 The blending cup assembly 20 has a cup cavity 2192, which can be used to hold food. The ratio of the volume V1 inside the cup cavity 2192 of the blending cup assembly 20 to the total enveloping volume V2 of the food processor 100 is greater than or equal to 0.45 and less than or equal to 0.68. The value of the volume V1 inside the cup cavity divided by the total enveloping volume V2 is greater than or equal to 0.45 and less than or equal to 0.68. For example, it can be 0.5, 0.55, 0.6, 0.66, etc. The total enveloping volume of the food processor 100 is the volume occupied by the entire food processor. The total enveloping volume V2 of the food processor 100 includes the sum of the volumes of the base 10, the lid 30, and the blending cup assembly 20.

[0074] By optimizing the ratio of the volume of the cup cavity 21 of the blending cup assembly 20 to the overall enveloping volume of the blender 100, the spatial layout of the blender 100 is more rational. While meeting the capacity requirements of the cup cavity, the overall size of the blender is smaller, making it easier to store. Furthermore, the installation stability of the blending cup assembly 20 within the blender is improved. During blending, the vibration amplitude of the blending cup assembly 20 is reduced, alleviating resonance with other components of the blender and thus reducing noise generated during blending. Moreover, the optimized volume ratio helps optimize the airflow path inside the blender 100. During blending, air can flow more smoothly between the cup cavity 2192 and the outer casing, avoiding air turbulence. Air turbulence causes fluctuations in air pressure, resulting in noise; the optimized airflow reduces these pressure fluctuations, thereby reducing noise.

[0075] In an optional embodiment, the base 10 has a square orthographic projection in the horizontal plane; the stirring cup assembly 20 includes a stirring cup 21, which includes a cup body 219 and a handle 218 connected to the cup body 219. Both the cup body 219 and the cup cavity 2192 have square orthographic projections in the horizontal plane. See also... Figure 6 , Figure 7 and Figure 9 As shown, the extension directions of two adjacent sides of the square are a first direction X and a second direction Y that are perpendicular to each other in the horizontal plane, and the stirring cup assembly and the support base are arranged in the second direction Y.

[0076] In this way, the mixing cup 21 can be made shorter while maintaining the same volume, and the square cup body 219 can better achieve turbulence when mixing ingredients, which is beneficial for better pulverization of ingredients. The square shape can be square or rectangular, and rounded corners can be provided at the corners. The square base 10 and the square mixing cup assembly 20 are adapted to each other and can both be square or rectangular.

[0077] In an optional embodiment, the length D1 of the orthographic projection of the cup body 219 in the horizontal plane in the first direction X, the length L1 in the second direction Y, and the height H1 of the cup cavity 2192, are related to the length D2 of the orthographic projection of the base 10 of the food processor 100 in the horizontal plane in the first direction X, the length L2 in the second direction Y, and the overall height H2 of the food processor 100 by the following equation:

[0078] L2 <L1+70mm;

[0079] H2

[0080] D2 = D1 + d, where d is greater than or equal to 0 and less than or equal to 15 mm.

[0081] ​In some embodiments, when the food processor 100 is placed normally, the support base 12 and the mixing cup assembly 20 are distributed front to back, with the second direction Y being the front-to-back direction and the first direction X being the left-to-right direction. The length D2 of the orthographic projection of the base 10 of the food processor 100 in the horizontal plane in the first direction X can be the distance between two opposite sides where the base 11 and the support base 12 intersect.

[0082] In some embodiments, d can be equal to 0. When d is equal to 0, the length D2 of the orthographic projection of the base 10 in the horizontal plane in the first direction X is equal to the length D1 of the orthographic projection of the cup body 219 in the horizontal plane in the first direction X. The dimensions of the base 10 and the cup body 219 are equal in the left-right direction. In some other embodiments, d can be greater than 0, and the length of the base 10 in the first direction X can be slightly larger.

[0083] The dimensions of the cup body 219, the base 10 of the food processor 100, and the overall height of the machine have been optimized. This optimizes the horizontal and vertical dimensions of the cup cavity 2192 and the food processor 100, making the space for blending ingredients and the overall space of the food processor 100 more reasonable. The spatial layout of the food processor 100 is more reasonable, the installation stability of the blending cup assembly 21 in the whole machine is improved, the noise generated by the food processor 100 during use is reduced, and the user experience of the food processor 100 is enhanced.

[0084] In an optional embodiment, the stirring cup 21 includes a cup base plate disposed at the bottom of the cup body 219. The cup base plate may be a heating plate 22 or a base plate without heating function. The stirring cup assembly 20 includes a cup lid assembly 22 covering the stirring cup 21. The cup body 219, the cup base plate, and the cup lid assembly 22 form a cup cavity 2192, and the height of the cup cavity 2192 is the vertical distance between the cup base plate and the cup lid assembly 22.

[0085] The lid assembly 22 has a minimal impact on the internal volume of the cup cavity 2192. This facilitates the setting of the dimensions of the cup cavity 2192, simplifying the design process of the blender 100. The height of the cup cavity 2192 can be any vertical distance from the base of the cup to the lid assembly 22. The height of the lid assembly 22 is relatively small compared to the height of the cup body 219, thus having a minimal impact on the overall internal volume of the cup cavity.

[0086] In an optional embodiment, the height H1 of the cup cavity 2192 ranges from 120mm to 220mm, and the overall height H2 of the blender 100 ranges from 260mm to 330mm. For example, the height H1 of the cup cavity 2192 can be 130mm, 155mm, 160mm, 165mm, 170mm, 175mm, 180mm, 185mm, 190mm, 195mm, 200mm, etc. For example, the overall height H2 of the blender 100 can be 265mm, 270mm, 275mm, 280mm, 285mm, 290mm, 295mm, 300mm, 305mm, 310mm, 315mm, 320mm, 325mm, etc.

[0087] Thus, by optimizing the height H1 of the cup cavity 2192 and the overall height H2 of the food processor 100, the spatial layout of the food processor 100 is more reasonable, the installation stability of the mixing cup assembly 20 within the whole machine is improved, the vibration amplitude of the mixing cup assembly 20 during blending is reduced, and the resonance phenomenon between it and other parts of the whole machine is alleviated, thereby reducing the noise generated by the food processor 100 during blending. Furthermore, the optimized height H1 of the cup cavity 2192 is beneficial for the turbulence effect of the ingredients within the cup cavity 2192, improving the circulation of ingredients, reducing the risk of the blade assembly 23 running idle, and allowing the ingredients to fully contact the blade assembly 23, resulting in smaller particle sizes after pulverization, thereby improving the texture of the food processed by the food processor 100. When the height of the cup cavity 2192 is too high, the ingredients may not be able to fully contact the blades, leading to uneven blending; while if the height of the cup cavity 2192 is too low, the ingredients may be too restricted during blending, failing to form good tumbling and circulation. By optimizing the height, the ingredients can fully contact the blades during blending, resulting in better blending effects.

[0088] In some embodiments, the height H1 of the cup cavity 2192 ranges from 155mm to 200mm, and the overall height H2 of the food processor 100 ranges from 265mm to 330mm.

[0089] This helps reduce noise generated during the use of the food processor. It also improves the flow of food within the cup, resulting in smaller, more pulverized particles and thus enhancing the texture of the food processed by the food processor.

[0090] Figures 10 to 13 The results are from noise tests conducted on two different food processors (model 100). Figure 10 and Figure 11 The results of a noise test on a food processor. Figure 12 and Figure 13 This is the noise test result for another type of food processor.

[0091] The noise generated by the blender 100 during use was tested under different dimensions, including the length D2 of the orthographic projection of the base 10 in the horizontal plane in the first direction X, the length L2 in the second direction Y, the overall height H2 of the blender 100, the length D1 of the orthographic projection of the cup body 219 in the horizontal plane in the first direction X, the length L1 in the second direction Y, and the height H1 of the cup cavity 2192.

[0092] The tests revealed that lengths D2, L2, D1, and L1 had minimal impact on noise levels; extreme value tests showed minimal noise differences. During the tests, the area of ​​the fixed base 10 projected onto the horizontal plane was 25900 mm². 2 -32000mm 2 With one value remaining constant, the area of ​​the orthographic projection of the fixed cup body 219 onto the horizontal plane is 25600 mm². 2 -19600mm 2 One of the following values ​​remains constant. Length L2 is 185mm-200mm; length D2 is 140mm-160mm; length L1 equals length D1, which is 140mm-160mm. In this test, L2 = 194mm, D2 = 150mm, L1 = D1 = 150mm, and the overall height H2 of the food processor 100 and the height H1 of the cup cavity 2192 are changed.

[0093] from Figure 10 and Figure 11 The test results show that the overall height H2 of the machine ranges from 265mm to 315mm, and the height H1 of the cup cavity 2192 is 155mm, 160mm, 165mm, 175mm, 180mm, 185mm, 190mm, 195mm, and 200mm respectively. The maximum noise generated by the food processor 100 during blending does not exceed 80 decibels. From Figure 12 and Figure 13 The test results show that as the overall height H2 increases from 265mm to 330mm, the height H1 of the cup cavity 2192 remains the same. Figure 10 and Figure 11 The test results showed that the maximum noise generated by the food processor 100 during blending did not exceed 80 decibels. Both sets of test results indicated low noise levels. Therefore, it can be concluded that the height H1 of the cup cavity 2192 ranges from 155mm to 200mm, and the overall height H2 of the food processor 100 ranges from 265mm to 330mm, indicating low noise during blending.

[0094] In an optional embodiment, the height H1 of the cup cavity 2192 ranges from 170mm to 190mm, and the overall height H2 of the food processor 100 ranges from 275mm to 315mm. This configuration better reduces noise generated during operation, improving the user experience. Furthermore, it enhances the turbulence of ingredients within the cup cavity, significantly reducing the particle size of the pulverized ingredients and thus improving the texture of the processed food.

[0095] exist Figure 10 and Figure 11 In the tests, the height H1 of the cup cavity 2192 ranged from 170mm to 190mm, and the overall height H2 of the blender 100 ranged from 275mm to 395mm. The noise generated by the blender 100 during use could be controlled within 70 decibels. Figure 12 and Figure 13 In the tests, the height H1 of the cup cavity 2192 ranged from 170mm to 190mm, and the overall height H2 of the blender 100 ranged from 290mm to 315mm. The noise generated by the blender 100 during use could be controlled within 70 decibels. It can be concluded that with the height H1 of the cup cavity 2192 ranging from 170mm to 190mm and the overall height H2 of the blender 100 ranging from 275mm to 315mm, noise can be further reduced.

[0096] In an optional embodiment, the motor 40 is located at the bottom of the mixing cup 21. The motor 40 includes an output shaft 41, and the blade assembly 23 is located at the top of the output shaft 41, inside the mixing cup 21. The overall height H2 of the food processor 100 ranges from 275mm to 295mm. The height H1 of the cup cavity 2192 ranges from 170mm to 190mm.

[0097] Thus, the output shaft 41 of the motor 40 is directly connected to the blade assembly 23, forming a direct-drive structure, which can reduce the height of the food processor 100. The optimization of the overall height H2 is beneficial to the noise reduction of the direct-drive food processor 100, and also to the turbulence effect of the ingredients in the cup cavity 2192 of the direct-drive food processor 100, improving the circulation of the ingredients, and making the particle size of the crushed ingredients smaller, thereby improving the taste of the ingredients processed by the food processor.

[0098] Figure 10 and Figure 11 The noise test results for the direct-drive blender show that when the overall height H2 of the blender 100 is between 275mm and 295mm, and the height H1 of the cup cavity 2192 is between 170mm and 190mm, the noise generated by the blender 100 during use can be controlled within 70 decibels, which is quieter.

[0099] In one example, the overall height H2 of the food processor 100 is 285mm, and the height H1 of the cup cavity 2192 is 181mm. However, it is not limited to the above example.

[0100] In other embodiments, the motor 40 is located inside the base 11, and the blade assembly 23 is located inside the mixing cup 21. When the mixing cup assembly 20 is assembled on the base 11, the blade assembly 23 is connected to the motor 40. The food processor 100 is a modular food processor. The overall height H2 of the food processor ranges from 290mm to 315mm.

[0101] The blade assembly 23 is located inside the mixing cup 21, and the motor 40 is located on the base 11. It is a split structure. The optimization of the overall height H2 can better reduce the noise of the split structure food processor 100, and also better improve the turbulence effect of the ingredients in the cup cavity of the split structure food processor 100. The particle size of the ingredients after being crushed is smaller, thereby improving the taste of the ingredients processed by the food processor.

[0102] Figure 12 and Figure 13 The results show the noise levels of the detachable blender. The test results indicate that when the overall height H2 of the blender 100 ranges from 290mm to 315mm, and the height H1 of the cup cavity 2192 ranges from 170mm to 190mm, the noise generated by the blender 100 during use can be controlled within 70 decibels, resulting in lower noise levels.

[0103] In one example, the overall height H2 of the food processor 100 is 307mm, and the height H1 of the cup cavity 2192 is 181mm. However, it is not limited to the above example.

[0104] In optional embodiments, the length D1 of the orthographic projection of the cup body 219 in the horizontal plane in the first direction X ranges from 100mm to 160mm, for example, 110mm, 120mm, 130mm, 140mm, and 150mm. The length L1 of the orthographic projection of the cup body 219 in the horizontal plane in the second direction Y ranges from 100mm to 160mm, for example, 110mm, 120mm, 130mm, 140mm, and 150mm. The reasonable setting of the length and width dimensions of the cup body 219 is beneficial to the turbulence effect of the food within the cup cavity 2192, improving food circulation, reducing or avoiding dead zones in the mixing process, and ensuring that all the food within the cup cavity can participate in the mixing process, resulting in smaller particle sizes after the food is pulverized, thereby improving the texture of the food processed by the food processor 100. In some embodiments, the length D1 of the orthographic projection of the body 219 in the horizontal plane in the first direction X ranges from 140mm to 160mm, and the length L1 in the second direction Y ranges from 140mm to 160mm. This can improve the mixing effect. The combination of the length D1 of the orthographic projection of the cup body 219 in the first direction X and the length L1 in the second direction Y, as well as the height H1 of the cup cavity 2192, makes the dimensions of the mixing cup assembly 20 coordinated, with high stability and low noise. It also facilitates the turbulence of the food in the cup cavity 2192, resulting in a good pulverizing effect.

[0105] In an optional embodiment, the length D2 of the base 10 of the food processor 100 projected onto the horizontal plane in the first direction X ranges from 140mm to 160mm, and the length L2 in the second direction Y ranges from 185mm to 200mm. For example, length D2 is 145mm, 150mm, or 155mm. For example, length L2 is 190mm or 195mm. The food processor's dimensions are well-proportioned, making it more stable when placed on a countertop.

[0106] In an optional embodiment, the thickness of the cup body 219 ranges from 5 mm to 12 mm, for example, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, or 11 mm.

[0107] Specifically, the side walls of the cup body 219 are typically made of glass, which has a uniform density. This design prevents the mixing cup assembly 20 from being too heavy and makes it easier to handle.

[0108] In an optional embodiment, the volume inside the cup cavity 2192 is the product of the length D1 of the orthographic projection of the cup body 219 in the horizontal plane in the first direction X, the length L1 in the second direction Y, and the height H1 of the cup cavity 2192.

[0109] The sidewall thickness of the cup body 219 has little impact on the internal volume of the cup cavity 2192. Using the dimensions of the cup body 219 to determine the internal volume of the cup cavity 2192 makes it easier to set the dimensions of the cup cavity 2192 and the cup body 219, which facilitates design and manufacturing.

[0110] The overall volume of the food processor 100 is the product of the length D2 of the orthographic projection of the base 11 in the horizontal plane in the first direction, the length L2 in the second direction, and the overall height H2 of the food processor 100. This facilitates setting the size of the blending cup and the overall dimensions of the machine, simplifying design and manufacturing.

[0111] In an optional embodiment, the length D1 of the orthographic projection of the cup body 219 in the horizontal plane in the first direction X is less than or equal to the length L1 in the second direction Y, and the relationship between the height H1 of the cup cavity 2192 and the length L1 in the second direction Y is as follows:

[0112]

[0113] By setting a reasonable size relationship between the cup chambers (2192), it is beneficial to increase the turbulence effect, reduce the dead corners of mixing, improve the efficiency of food circulation, and optimize the taste of the food processed by the food processor (100). Furthermore, it ensures that the dimensions of the food processor (100) are coordinated and reasonable in both horizontal and vertical directions, allowing for a more rational overall spatial layout, making the food processor (100) more stable and quieter.

[0114] The volume of the cavity 2192 is V1 = L1 * H1 * D1. Substituting this into equation (1), we get:

[0115]

[0116] The total enveloping volume of the food processor 100 is V2 = L2 * H2 * D2. Further, the relationship α between the volume of the cup cavity V1 and the total enveloping volume V2 is obtained:
