Description

Technical Field

[0001] This application relates to the field of small household appliance technology, and in particular to the main unit of a food processor and the food processor itself. Background Technology

[0002] The food processor includes a main unit and a blending jar assembly. The main unit includes a motor. The blending jar assembly includes a blending jar and a blade assembly. The motor drives the blade assembly of the blending jar assembly to rotate within the blending jar.

[0003] Technicians discovered that the main unit of the aforementioned food processor was quite noisy when it was in operation. Utility Model Content

[0004] The purpose of this application is to disclose a main unit for a food processor and a food processor. The main unit for the food processor has low noise and meets safety regulations.

[0005] This application discloses a main unit for a food processor. The main unit includes a base, a housing, and a drive assembly. The drive assembly includes a motor; the base includes a baffle extending upwards and surrounding the motor; the housing is assembled with the base, and the housing surrounds the baffle to form a double-layer structure; the base has a ventilation opening communicating with the interior of the housing.

[0006] As described above, since the outer shell and the base are assembled together, and the outer shell surrounds the baffle, a double-layer structure is formed. The double-layer structure helps to reduce noise, resulting in low noise from the main unit of the food processor. At the same time, the main unit of the food processor dissipates heat from the motor through the ventilation vent, meeting safety requirements.

[0007] In some embodiments, the vent includes an air inlet and an air outlet, and the base further includes a first air inlet channel and an air outlet channel that are isolated from each other, the first air inlet channel being connected to the air inlet and the air outlet channel being connected to the air outlet.

[0008] As described above, since the air inlet, air outlet, first air inlet channel, and air outlet channel are all located on the base, and the first air inlet channel and air outlet channel are isolated from each other, the air enters from the air inlet, then enters the motor cavity, and then exits from the air outlet at the bottom. The air travels a longer path, and the air inlet and outlet do not affect each other, which is beneficial for heat dissipation of the motor.

[0009] In some embodiments, the baffle forms a motor cavity, and the base is further provided with a fan cavity to accommodate the fan, and the fan cavity, the motor cavity, and the air outlet channel are connected to each other.

[0010] As described above, the base also has a fan cavity to accommodate the fan. The fan cavity, the motor cavity, and the air outlet channel are connected. In this way, the fan allows air to circulate from the top of the motor to the bottom, which is beneficial for heat dissipation of the motor.

[0011] In some embodiments, the baffle forms a motor cavity, and the baffle and the outer casing form a second air inlet channel; the second air inlet channel connects the first air inlet channel and the motor cavity.

[0012] As described above, since the base includes an air inlet and an air outlet, the baffle and the outer casing form a second air intake channel. Because the baffle extends upward and the first air intake channel is located on the base, the second air intake channel has a bend relative to the first air intake channel. Even if water enters from the air inlet, it cannot move upward and enter the interior of the food processor (such as the motor) because the first air intake channel has a certain length, the bend, and the upward-extending second air intake channel. This prevents water and other liquids from damaging the internal components of the food processor and meets safety regulations.

[0013] In some implementations, the first air intake channel bends back and forth in the vertical direction.

[0014] As described above, since the first air intake channel bends back and forth in the vertical direction, even if water enters, it will be blocked multiple times, thus making it difficult for water to enter the second air intake channel or the interior of the food processor (such as the motor). While meeting the requirements for heat dissipation of the motor and noise reduction, the food processor meets the safety requirements.

[0015] In some embodiments, the base includes a base body and a base cover, the base cover covering the base body to form the first air intake channel; the base cover includes an upper blocking portion extending toward the base body; the base body includes a lower blocking portion extending toward the base cover; the lower blocking portion and the upper blocking portion partially overlap in the height direction of the main unit of the food processor to achieve the bending.

[0016] As described above, since the lower blocking part and the upper blocking part overlap in the height direction of the main unit of the food processor to achieve the bending, the upper blocking part and the lower blocking part can block water respectively, forming multiple layers of barriers. Therefore, water and other substances are less likely to enter the second air intake channel and enter the interior of the main unit of the food processor (such as the motor). While meeting the requirements for heat dissipation of the motor and noise reduction, the main unit of the food processor meets the safety requirements.

[0017] In some embodiments, the base includes a base body and a base cover covering the base body, the base cover including the baffle and a cover plate extending laterally; the outer shell is connected to the cover plate, and the orthographic projection area of ​​the outer shell in the horizontal plane is smaller than the orthographic projection area of ​​the base body in the horizontal plane.

[0018] As described above, the projected area of ​​the outer shell on the horizontal plane is smaller than the projected area of ​​the base body on the horizontal plane. This results in a larger base size, which ensures better stability of the food processor's main unit while meeting the requirements for motor heat dissipation and noise reduction. Meanwhile, the smaller outer shell size makes it easier to hold.

[0019] In some embodiments, the vent includes an air inlet, and the cover plate and the base body cover each other to form a first air inlet channel, which communicates with the air inlet. The cover plate includes an annular portion located on the outer side of the housing, and a connecting hole located between the housing and the baffle; the baffle and the housing form a second air inlet channel; the connecting hole connects the first air inlet channel and the second air inlet channel, and there are multiple connecting holes, which are spaced apart from each other in the circumferential direction.

[0020] As described above, there are multiple connecting holes, which are spaced apart from each other in the circumferential direction. While ensuring smooth airflow, the spacing between adjacent connecting holes can prevent water from entering the second air intake channel. Thus, while meeting the requirements for motor heat dissipation and noise reduction, the main unit of the food processor meets safety regulations.

[0021] In some embodiments, the main unit of the food processor satisfies at least one of the following dimensions: a) the diameter of the orthographic projection of the base body in the horizontal plane is e, 100mm≤e≤175mm; b) the diameter of the orthographic projection of the outer shell in the horizontal plane is f, 90mm≤f≤155mm; c) the height of the outer shell is c, 95mm≤e≤200mm; d) the height of the base is d, 10mm≤d≤40mm.

[0022] As described above, the main unit of the food processor can meet any of the above dimensions, which can make the main unit of the food processor smaller in size, easier to hold, and / or ensure good stability.

[0023] In some embodiments, the base satisfies at least one of the following features:

[0024] a) The number of air inlets exceeds the number of air outlets, and the air inlets and outlets are spaced apart on the periphery of the base. As described above, since the number of air inlets exceeds the number of air outlets, more air is drawn in, which is beneficial for cooling the motor and other components of the food processor. Furthermore, the spaced distribution of the air inlets and outlets on the periphery of the base ensures that the air intake and exhaust are in different directions, preventing the mixing of cold and hot air and further facilitating cooling of the motor and other components inside the food processor.

[0025] b) The air intake volume of the air inlet is greater than or equal to the air outlet volume. As described above, since the air intake volume is greater than the air outlet volume, there is sufficient airflow to dissipate heat from the internal components of the food processor (such as the motor; of course, there may be other components in the second air intake channel, such as the control board, etc.). This is more conducive to heat dissipation from the components inside the food processor.

[0026] c) The air outlet channel includes an arc-shaped air guide wall, and the base is also provided with a fan cavity to accommodate the fan. The air guide wall is tangent to the fan cavity wall of the fan cavity. As described above, since the air guide wall is tangent to the fan cavity wall of the fan cavity, the air guide wall directs the airflow, making it easier for the air to flow to the air outlet, thereby helping to reduce noise.

[0027] In some embodiments, the main unit of the food processor includes a gasket that is assembled to the base and protrudes from the bottom of the base.

[0028] As described above, by setting the washer, which protrudes from the bottom of the base, when the main unit of the food processor or the food processor is placed on the work surface, the washer contacts the work surface, resulting in good stability of the main unit of the food processor or the food processor.

[0029] In some embodiments, the drive assembly includes a gearbox. The main unit of the food processor includes a top cover. The top cover includes an insertion portion. The top cover is assembled to the housing, and the insertion portion is inserted into the housing. The insertion portion forms a receiving cavity; the gearbox is inserted into the receiving cavity.

[0030] As described above, the insertion part is inserted into the outer casing, and the gearbox is located within the receiving cavity. This arrangement satisfies the requirements for heat dissipation and noise reduction of the motor, while also contributing to a small size and easy handheld operation of the food processor's main unit. Furthermore, the food processor's main unit includes a drive assembly, which can be assembled with either the top cover or the outer casing. Additionally, the outer casing is assembled with the top cover, surrounds the baffle, and stands on the top surface of the base. This makes the assembly of the food processor's main unit simple and convenient.

[0031] Secondly, this application discloses a food processor. The food processor includes any of the aforementioned main unit, a blending jar assembly, and a blending blade assembly. The drive assembly includes a gearbox assembly connected to the motor, the gearbox assembly including an output end connected to the blending blade assembly, the blending blade assembly being located within the blending jar assembly. When the main unit of the food processor is placed upright, the blending jar assembly is located above the main unit. When the main unit of the food processor is placed upside down, the blending jar assembly is located below the main unit.

[0032] As described above, the food processor has at least the beneficial effects of the main unit of the food processor. Attached Figure Description

[0045] See Figure 6 and Figure 7 and combined Figure 3 , Figure 4 , Figure 5 , Figure 9 and Figure 10 This application discloses a main unit 1000 for a food processor. The main unit 1000 includes a base 1, a housing 2, and a drive assembly 3. In some embodiments, the main unit 1000 also includes a top cover 4. See also... Figure 2 and combined Figure 4 and Figure 5In one usage state of the main unit of the food processor, the base 1 serves as a carrier for related components of the food processor, and other components of the food processor are supported by the base 1. The drive assembly 3 includes a motor 31. The base 1 includes a baffle 151 extending upward and surrounding the motor 31. The upward extension refers to extending in a direction away from the table surface where the food processor is placed. The outer shell 2 is assembled with the base 1, and the outer shell 2 surrounds the baffle 151 to form a double-layer structure. The base 1 is provided with a ventilation opening communicating with the interior of the outer shell 2. The function of the ventilation opening is to allow air to enter the interior of the main unit of the food processor and to allow air inside the main unit of the food processor to exit. In the embodiments of this application, the ventilation opening includes an air inlet 13 and an air outlet 14.

[0046] As described above, since the outer shell 2 is assembled with the base 1 and the outer shell 2 surrounds the baffle 151, a double-layer structure is formed. The double-layer structure helps to reduce noise (resulting in lower noise from the food processor main unit); at the same time, the ventilation openings are provided to dissipate heat from the motor, meeting safety requirements.

[0047] See Figure 6 and Figure 7 and combined Figure 3 The base 1 includes a first air inlet channel 11 and an air outlet channel 12 that are isolated from each other. The first air inlet channel 11 is connected to an air inlet 13, and the air outlet channel 12 is connected to an air outlet 14. The number and shape of the air inlets 13 and air outlets 14 are not limited, as long as they can realize air intake and air exhaust.

[0048] As described above, since the air inlet 13, air outlet 14, first air inlet channel 11, and air outlet channel 12 are all located on the base 1, and the first air inlet channel 11 and air outlet channel 12 are isolated from each other, the air enters from the air inlet 13, then enters the motor cavity 15, and then exits from the air outlet 14 at the bottom. The air travels a longer path, and the air inlet and outlet do not affect each other (generally, the air inlet is cold air, and the air outlet is hot air formed by the heat carried away by the motor). Therefore, it is beneficial for heat dissipation of the motor.

[0049] Of course, the air inlet 13, air outlet 14, etc. are not limited to the above-mentioned configuration, as long as they can dissipate heat from the motor 31.

[0050] In some embodiments, the baffle 151 forms a motor cavity 15. In embodiments of this application, the base 1 also has a fan cavity 16 for accommodating the fan 32, and the fan cavity 16, the motor cavity 15, and the air outlet duct 12 are interconnected. In embodiments of this application, the drive assembly 3 includes a motor 31 located in the motor cavity 15, a fan 32 located in the fan cavity 16, and a gearbox assembly 33 connected to the motor 31. The structure of the gearbox assembly 33 is not limited, as long as it enables the food processor to output multiple speeds. In this embodiment, the food processor can output three speeds. In some embodiments, it can also output only one speed, for example, the gearbox assembly 33 is a reduction gear.

[0051] As described above, since the base 1 is also provided with a fan cavity 16 to accommodate the fan 32, the fan cavity 16, the motor cavity 15 and the air outlet channel 12 are connected. Thus, the fan allows air to flow from the top to the bottom of the motor, which is beneficial for heat dissipation of the motor 31.

[0052] Of course, the positional relationship between the fan cavity 16, the motor cavity 15 and the air outlet duct 12 is not limited to this, as long as it can dissipate heat from the motor 31.

[0053] In some embodiments, the baffle 151 forms a motor cavity 15, and the baffle 151 and the outer casing 2 constitute a second air intake channel 17. There are various ways to construct the second air intake channel 17. For example, the outer casing 2 is assembled with the upper cover 4, the outer casing 2 surrounds the baffle 151, and stands on the top surface of the base 1. In this way, the baffle 151, the upper cover 4, the gearbox assembly 33, and the outer casing 2 form the second air intake channel 17. The second air intake channel 17 connects the first air intake channel 11 and the motor cavity 15.

[0054] See Figure 6 and Figure 7 As shown by the dashed arrow, during the heat dissipation process of the main unit of the food processor, the motor 31 rotates, driving the fan 32 to rotate. Then, the air outside the main unit of the food processor enters the first air intake channel 11 from the air inlet 13, enters the second air intake channel 17, flows upward in the second air intake channel 17, then enters the motor cavity 15, flows downward into the fan cavity 16, then flows into the air outlet channel 12, and finally is discharged from the air outlet 14.

[0055] With the above configuration, the main unit of the food processor has at least the following beneficial effects:

[0056] a) Since the base includes an air inlet 13 and an air outlet 14, the baffle 151 and the outer casing 2 form a second air intake channel 17. Because the baffle 151 extends upward (e.g., vertically upward), and the first air intake channel 11 is located on the base 1, the second air intake channel 17 has a bend relative to the first air intake channel 11. Even if water enters from the air inlet 13, it cannot move upward and enter the interior of the food processor (e.g., the motor, for example, it enters the motor cavity 15 along the second air intake channel 17 and passes through the relevant parts of the motor 31) due to the length of the first air intake channel 11, the bend, and the arrangement of the second air intake channel 17. This prevents water and other liquids from damaging the internal components of the food processor and meets safety requirements.

[0057] b) The air duct formed by the first air intake channel 11 and the second air intake channel 17 is relatively long, which is also conducive to reducing noise.

[0058] See Figure 6 The first air inlet channel 11 bends back and forth in the vertical direction. The components that make up the bend are not limited.

[0059] As described above, since the first air intake channel 11 bends back and forth in the vertical direction, even if water enters, it will be blocked multiple times, thus making it difficult for it to enter the second air intake channel 17 and related parts such as the motor 31. While meeting the heat dissipation requirements, the main unit of the food processor meets the safety requirements.

[0060] See Figure 6 , Figure 8 and Figure 9 and combined Figure 3 and Figure 7 The base 1 includes a base body 10 and a base cover 20. The base cover 20 covers the base body 10 to form the first air inlet channel 11. The arrangement of the cover to form the first air inlet channel 11 is not limited; the structure of the first air inlet channel 11 of this application is described below: See [link to relevant documentation]. Figure 9 The base body 10 includes a base body 101, multiple partitions 102, and a protrusion 103 located at the center of the base body 101. The protrusion 103 includes a protrusion cavity 1031. The air inlet 13 and the air outlet 14 are correspondingly provided on the peripheral wall of the base body 101. The base body 101, the protrusion 103, and the corresponding partitions 102 form a first cavity 104, a second cavity 105, and a third cavity 106. Figure 4 , Figure 5 , Figure 6 and Figure 7When the upper cover 20 of the base is installed on the base body 10, it covers the first cavity 104 and the second cavity 105 respectively, forming a first air inlet channel 11. Covering the third cavity 106 forms the air outlet channel 12. The lower cover 30 of the base 1 covers the protruding cavity 1031, forming the fan cavity 16. In some embodiments, the lower cover 30 of the base can be integrally formed with the base body 10.

[0061] See Figure 8 and Figure 6 The base cover 20 includes an upper blocking portion 200 extending toward the base body 10; the base body 10 includes a lower blocking portion 100 extending toward the base cover 20. The lower blocking portions 100 are located within the first cavity 104 and the second cavity 105, respectively. See also Figure 6 The lower blocking portion 100 and the upper blocking portion 200 overlap in the height direction of the main unit of the food processor to achieve the bending. Figure 6 The overlapping distance is shown as 'a'.

[0062] As described above, since the lower blocking part 100 and the upper blocking part 200 overlap in the height direction of the main unit of the food processor to achieve the bending, the upper blocking part 200 and the lower blocking part 100 can block water respectively, forming multiple layers of barriers. Therefore, water and other substances are less likely to enter the second air intake channel 17 and enter the interior of the main unit of the food processor (such as the motor 31 and related parts). While meeting the requirements for heat dissipation of the motor and noise reduction, the main unit of the food processor meets the safety requirements.

[0063] See Figure 4 , Figure 5 , Figure 6 and Figure 7 The base 1 includes a base body 10 and a base cover 20 covering the base body 10. The base cover 20 includes the baffle 151 and a cover plate 152 extending laterally. The outer shell 2 is connected to the cover plate 152. The orthographic projection area of ​​the outer shell 2 in the horizontal plane is smaller than the orthographic projection area of ​​the base body 10 in the horizontal plane. In the embodiments of this application, the outer shell 2 is columnar to achieve that the orthographic projection area of ​​the outer shell 2 in the horizontal plane is smaller than the orthographic projection area of ​​the base body 10 in the horizontal plane, but it is not limited to this.

[0064] As described above, since the projected area of ​​the outer shell 2 on the horizontal plane is smaller than the projected area of ​​the base body 10 on the horizontal plane, the base 1 has a larger size in the xy direction (the upward direction can be considered as the z direction, and in the case of a circular base 1, the xy direction is the radial direction of the circle). Under the premise of meeting the requirements for heat dissipation of the motor and noise reduction, the stability of the food processor main unit is better; while the outer shell 2 has a smaller size in the xy direction, which is convenient to hold.

[0065] See Figure 8 and combined Figure 4 , Figure 5 , Figure 6 and Figure 7 The ventilation opening includes an air inlet 13, and the cover plate 152 and the base body 10 cover each other to form a first air intake channel 11. The first air intake channel 11 communicates with the air inlet 13. See also Figure 4 and Figure 5 The cover plate 152 includes an annular portion 153 located on the outer side of the outer casing 2, that is, the annular portion 153 surrounds the outer casing 2, and see also... Figure 8 The connecting hole 154 is located between the outer casing 2 and the baffle 151. (See also...) Figure 8 There are multiple connecting holes 154, which are spaced apart from each other in the circumferential direction.

[0066] As described above, since there are multiple connecting holes 154 spaced apart circumferentially, the spacing 155 between adjacent connecting holes 154 prevents water from entering the second air intake channel 17 while ensuring smooth airflow. Thus, the food processor meets safety regulations while satisfying the requirements for heat dissipation and noise reduction of the motor 31. Furthermore, because the annular portion 153 is located on the outside of the outer casing 2 and is part of the base 1, the base 1 is larger than the outer casing 2. This ensures good stability of the food processor while still meeting the requirements for heat dissipation and noise reduction of the motor 31, and the smaller size of the outer casing 2 makes it easier to hold.

[0067] See Figure 6 and combined Figure 7 The main unit of the food processor shall meet at least one of the following dimensions:

[0068] a) The diameter of the orthographic projection of the base 1 on the horizontal plane is e, 100mm≤e≤175mm, for example, 100mm, 103mm, 105mm, 108mm, 110mm, 113mm, 115mm, 118mm, 120mm, 125mm, 128mm, 130mm, 135mm, 140mm, 143mm, 145mm, 148mm, 150mm, 153mm, 158mm, 160mm, 165mm, 170mm, 172mm or 175mm; if the orthographic projection of the base 1 is a circle, the diameter is the diameter of that circle; if the base 1 is of other shapes, the diameter is the diameter of the circumcircle of the orthographic projection of the base.

[0069] b) The diameter of the orthographic projection of the outer shell 2 on the horizontal plane is f, 90mm≤f≤155mm, for example, 90mm, 93mm, 95mm, 98mm, 100mm, 105mm, 108mm, 110mm, 113mm, 115mm, 118mm, 120mm, 125mm, 128mm, 130mm, 135mm, 140mm, 143mm, 145mm, 150mm, 152mm or 155mm; if the orthographic projection of the outer shell 2 is circular, the diameter is the diameter of the circle; if the orthographic projection of the outer shell 2 is of other shape, the diameter is the diameter of the circumcircle of the orthographic projection.

[0070] c) The height of the outer shell 2 is c, 95mm≤e≤200mm, for example, 95mm, 98mm, 100mm, 105mm, 110mm, 103mm, 108mm, 115mm, 118mm, 120mm, 125mm, 130mm, 135mm, 140mm, 143mm, 148mm, 150mm, 155mm, 160mm, 165mm, 170mm, 175mm, 180mm, 185mm, 190mm, 193mm, 198mm or 200mm;

[0071] d) The height of the base 1 is d, 10mm≤d≤40mm, for example, 10mm, 15mm, 18mm, 20mm, 23mm, 25mm, 28mm, 30mm, 33mm, 35mm, 38mm or 40mm.

[0072] As described above, the main unit of the food processor can meet any of the above dimensions, which can make the main unit of the food processor smaller in size, easier to hold, and / or ensure good stability.

[0073] The base 1 also satisfies at least one of the following features:

[0074] a) See Figure 4 and Figure 5 and combined Figure 9 and Figure 10 The number of air inlets 13 is greater than the number of air outlets 14. For example, there are two air inlets 13 and one air outlet 14. The air inlets 13 and air outlets 14 are distributed at intervals around the periphery of the base 1.

[0075] As described above, since the number of air inlets 13 is greater than the number of air outlets 14, more air is drawn in, which is beneficial for heat dissipation of components such as the motor inside the food processor. Furthermore, the spacing between the air inlets 13 and air outlets 14 on the periphery of the base 1 ensures that the air intake and exhaust are in different directions, preventing the mixing of cold and hot air and further facilitating heat dissipation of components such as the motor inside the food processor.

[0076] b) In some embodiments, the air intake volume of the air inlet 13 is greater than the air outlet volume of the air outlet 14.

[0077] As described above, since the air intake is greater than the air output, there is enough air to dissipate heat from the internal components of the food processor, such as the motor (e.g., the motor 31; of course, there may be other components in the second air intake channel 17, such as the control board, etc.). This is more conducive to dissipating heat from the internal components of the food processor.

[0078] c) See also Figure 10 and combined Figure 9 The air outlet duct 12 includes an arc-shaped air guide wall 121, and the base 1 is also provided with a fan cavity 16 for accommodating the fan 32. The air guide wall 121 is tangent to the fan cavity wall 161 of the fan cavity 16. Of course, the side of the air guide wall 121 located in the fan cavity 16 can be determined by the rotation direction of the fan 32.

[0079] As described above, since the air guide wall 121 is tangent to the fan cavity wall 161 of the fan cavity 16, the air guide wall 121 guides the air, making it easier for the air to flow to the air outlet 14, thereby helping to reduce noise.

[0080] See Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The main unit of the food processor includes a gasket 5, see [link / reference]. Figure 6 and Figure 7 The washer 5 is assembled to the base 1 and protrudes from the bottom of the base 1, as shown below. Figure 6 and Figure 7 The washer 5 is assembled to the base body 10. For example... Figure 6 and Figure 7 As shown, the distance by which the washer 5 protrudes from the base 1 is h.

[0081] As described above, by setting the washer 5, which protrudes from the bottom of the base 1, when the main unit of the food processor or the food processor is placed on the work surface, the washer 5 contacts the work surface, resulting in good stability of the main unit of the food processor or the food processor.

[0082] See Figure 6 and Figure 7 The drive assembly 3 includes a gearbox assembly 33. The main unit of the food processor includes a top cover 4. The top cover 4 includes an insertion part 41. The top cover 4 is assembled with the outer casing 2, and the insertion part 41 is inserted into the outer casing 2, for example, with a clearance fit after insertion. Figure 7 The gap is indicated as 'a'. The insertion part 41 surrounds the receiving cavity 411. The gearbox assembly 33 is located within the receiving cavity 411, for example, located behind the receiving cavity 411 and clearance-fitted with the side wall of the receiving cavity 411. Figure 7 The gap is shown as b.

[0083] As described above, the insertion part 41 is inserted into the outer casing 2, and the gearbox assembly 33 is located within the receiving cavity 411. This arrangement satisfies the requirements for heat dissipation and noise reduction of the motor, while also making the main unit of the food processor small in size and easy to hold. This structure, combined with the aforementioned base 1 and outer casing 2, further enhances the small size and ease of handling of the main unit. Furthermore, the main unit includes a drive assembly 3, which can be assembled with the top cover 4 or the outer casing 2. Additionally, the outer casing 2 is assembled with the top cover 4, surrounding the baffle 151 and standing on the top surface of the base 1. This makes the assembly of the main unit 1000 of the food processor simple and convenient.

[0084] Secondly, see Figure 1 and Figure 2 This application discloses a food processor. The food processor includes a main unit 1000, a blending cup assembly 2000, and a blending blade assembly, as described above. The drive assembly includes a gearbox assembly 33 connected to the motor. The gearbox assembly 33 includes an output end connected to the blending blade assembly. The blending blade assembly is located within the blending cup assembly 2000. See also... Figure 2 When the main unit 1000 of the food processor is placed upright, the blending cup assembly 2000 is located above the main unit 1000. In this case, the main unit 1000 of the food processor can be considered a bottom-mounted main unit. See [link to relevant documentation]. Figure 1 When the main unit 1000 of the food processor is placed upside down, the blending cup assembly 2000 is located below the main unit 1000. In this case, the main unit 1000 can be considered as a top-mounted main unit. Those skilled in the art will understand that the main unit 1000 can be assembled with different blending cup assemblies 2000 or with the same blending cup assembly 2000, whether the main unit 1000 is placed upright or upside down.

[0085] As described above, the food processor has at least the beneficial effects of the main unit of the food processor.

[0086] 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.
