Description

Technical Field

[0001] This application relates to small household appliances, and in particular to blending cup assemblies and food processors. Background Technology

[0002] The food processor includes a blending jar assembly and a base. The blending jar assembly, assembled with the base, includes a blending jar, a jar holder assembly, a motor, a blade assembly, a blade plate assembly, and a coupler. The blending jar is open-ended. The blade plate assembly is located at the bottom opening of the blending jar. The jar holder assembly is assembled with the blending jar. The motor is located within the jar holder assembly, passes through the blade plate assembly, and is connected to the blade assembly; the motor drives the blades of the blade assembly to rotate within the blending jar. The coupler is located within the jar holder assembly, at the bottom of the motor.

[0003] In the above configuration, the coupler is located at the bottom of the motor, and the height of the cup holder assembly is at least the sum of the height of the motor and the height of the coupler. This makes the cup holder assembly relatively tall (in some cases, the axial height of the cup holder assembly along the motor shaft is greater than 100mm). The tall cup holder assembly will make the blending cup assembly relatively tall, which will make it inconvenient for consumers to use the blending cup assembly or the food processor. Utility Model Content

[0004] The purpose of this application is to disclose a blending cup assembly and a food processor. The blending cup assembly has a low axial height along the motor shaft, making it convenient for consumers to use the food processor.

[0005] In a first aspect, this application discloses a mixing cup assembly. The mixing cup assembly includes a mixing cup, a blade assembly, a motor, a cup holder assembly, and a coupler. The cup holder assembly is assembled with the mixing cup, and the blade assembly and the mixing cup form a food processing cavity, including blades located within the food processing cavity. The motor is located within the cup holder assembly and drives the blades to rotate within the food processing cavity. The coupler is located within the cup holder assembly and also around the periphery of the motor; with the side where the cup holder assembly is located as the bottom of each component, the bottom surface of the coupler is not lower than the bottom surface of the motor.

[0006] As described above, since the coupler is located inside the cup holder assembly and also around the motor, and the bottom surface of the coupler is not lower than the bottom surface of the motor, the height of the cup holder assembly no longer includes the height of the coupler. Therefore, the height of the cup holder assembly along the axial direction of the motor shaft is relatively low, resulting in a lower height of the stirring cup assembly and making it convenient to use.

[0007] In some embodiments, the height difference between the bottom surface of the coupler and the bottom surface of the motor is y, where 0mm≤y≤5mm.

[0008] As set up above, since 0mm≤y≤5mm, it is further ensured that the height of the cup holder assembly no longer includes the height of the coupler. Therefore, the height of the cup holder assembly along the axial direction of the motor shaft is low, which makes the height of the stirring cup assembly low and convenient to use.

[0009] In some embodiments, the blade assembly includes a heating plate for forming the food processing chamber and a heating element disposed on the heating plate, the heating element including a bottom of the heating plate opposite to the heating plate; along the axial direction of the motor shaft of the motor, the top surface of the coupler is lower than the bottom of the heating element, and the distance between the two is n, 10mm≤n≤75mm.

[0010] As described above, since 10mm≤n≤75mm, and the bottom surface of the coupler is not lower than the bottom surface of the motor, the cup holder assembly has a lower axial height along the motor shaft, resulting in a lower height of the stirring cup assembly and easier use.

[0011] In some embodiments, the cutter head assembly includes a heating element, the heating element including a cold end; the coupler is located below the cold end.

[0012] As described above, since the heating element includes a cold end, the cold end will include a terminal block. The coupler is located below the cold end, which facilitates the connection between the heating plate and the coupler. In addition, since the temperature of the cold end is usually lower than that of the hot end, the coupler being located below the cold end allows the coupler to avoid the relatively high temperature area. Therefore, the above design reduces the heat transfer of the cutter head assembly to the coupler.

[0013] In some embodiments, the cup holder assembly includes a cup holder with a bottom, the bottom of which includes a mounting opening; the side of the coupler includes a slot that engages with the side wall of the mounting opening.

[0014] As described above, the coupler is secured to the side wall of the mounting port via a slot, facilitating coupler assembly and preventing it from wobbling.

[0015] In some embodiments, the cutter head assembly includes a heating plate and a heating element, the motor includes a front motor bracket and a motor shaft, the motor shaft is rotatably connected to the front motor bracket and also connected to a cutter assembly mounted on the cutter head assembly; the front motor bracket extends into the space enclosed by the heating plate and the heating element; the motor is assembled with the cup holder assembly.

[0016] As described above, since the motor is assembled with the cup holder assembly instead of the blade assembly, and the motor front bracket extends into the space enclosed by the heating element and the heating plate, this application eliminates the need for a mounting post compared to mounting the motor directly to a protruding heating plate or heating element. Therefore, the axial distance between the motor and the heating plate along the motor shaft is shorter, resulting in a lower height for the mixing cup assembly and easier removal from the base. Furthermore, assembling the motor with the cup holder assembly, compared to mounting the motor directly to the heating plate or heating element, offers several advantages. First, because the motor is not assembled with the blade assembly's mounting post, it prevents heat from the blade assembly from being transferred to the motor through the mounting post and corresponding screws. Second, because the motor is not assembled with the blade assembly, its vibrations will not cause vibrations in the heating plate, thus preventing poor sealing between the blade assembly and the mixing cup and avoiding leakage from the food processing chamber.

[0017] In some embodiments, the cup holder assembly includes a heating plate support, and the edge of the blade assembly is clamped by the bottom of the stirring cup and the heating plate support; the heating plate support includes a heat insulation portion, the heat insulation portion including a support opening axially extending through the motor shaft, and the front motor support passing through the support opening of the heating plate support. The heat insulation portion is located between the heating element and the front motor support; or, the heat insulation portion is located between the heating element and the front motor support, and the heat insulation portion is located between the heating plate and the front motor support.

[0018] As described above, by setting the heat insulation part, the motor front bracket passing through the bracket opening, and the positional relationship between the heat insulation part and the heating element and heating plate, the heat insulation part can isolate heat, further helping to prevent excessive heat from the heating plate and heating element from being transferred to the motor, and helping to prevent the motor from overheating during operation. Furthermore, in some embodiments, the heating plate bracket and the heating plate form a cavity, with the heating element located within the cavity. The heating plate bracket includes a cover plate facing the heating plate, and the motor is assembled on the cover plate. In this case, the height between the motor and the heating plate includes at least the sum of the axial distance between the cover plate and the heating plate along the motor shaft, the thickness of the cover plate, and the thickness of the nut. This results in a larger axial distance between the motor and the heating plate along the motor shaft, leading to a higher height of the food processor along the motor shaft, making it inconvenient to use. Compared with the aforementioned embodiments, the motor front bracket passes through the bracket opening of the heating plate bracket, and the height of the cup holder assembly is reduced by at least the thickness of the cover plate and the thickness of the related connecting parts. Therefore, the distance between the motor and the heating plate along the axial direction of the motor shaft is closer, which is beneficial to reducing the height of the cup holder assembly along the axial direction of the motor shaft. In turn, it is beneficial to reduce the height of the mixing cup assembly along the axial direction of the motor shaft, making it more convenient for consumers to use the food processor.

[0019] In some embodiments, the motor front bracket includes a top connecting portion and a connecting frame connected to the top connecting portion, the top connecting portion being rotatably connected to the motor shaft; the distance between the connecting frame and the heating plate along the axial direction of the motor shaft increases radially toward the heating element.

[0020] As described above, the axial distance between the connecting bracket and the heating plate along the motor shaft increases radially toward the heating element. Combined with the fact that the front bracket of the motor extends into the space enclosed by the heating plate and the heating element, and that the motor is assembled with the cup holder assembly, it is beneficial to reduce the height of the cup holder assembly along the motor shaft, thereby reducing the height of the stirring cup assembly and making it easier to use.

[0021] In some embodiments, the connecting frame includes a support sidewall that is shaped like a frustum or a truncated pyramid.

[0022] As described above, because the side walls of the bracket are shaped like a frustum or a truncated cone, the axial distance between the connecting frame and the heating plate along the motor shaft gradually increases. This allows for the assembly of motor components (such as enameled wire) inside the connecting frame and provides greater electrical clearance. Consequently, the motor itself is shorter (for example, shorter than the L-shaped motor formed by the first and second sections of the aforementioned motor front bracket). This helps reduce the axial height of the blending cup assembly along the motor shaft, making it more convenient for consumers to use the food processor. Of course, this design also helps prevent excessive heat transfer from the heating plate assembly to the motor.

[0023] In some embodiments, the heating element includes a bottom opposite to the heating plate; the projection of the motor front bracket on the heating plate is located within an annular area enclosed by the projection of the bottom of the heating element on the heating plate; or, the motor includes a motor housing, the front end of the motor housing is connected to the motor front bracket, and the projections of the motor front bracket and the front end of the housing on the heating plate are located within an annular area enclosed by the projection of the bottom of the heating element on the heating plate.

[0024] As described above, since the axial distance between the connecting bracket and the heating plate along the motor shaft increases in the radial direction of the motor shaft towards the heating element, and the projection of the motor front bracket on the heating plate is located within the annular area enclosed by the projection of the bottom of the heating element on the heating plate, or the projections of the motor front bracket and the front end of the motor housing on the heating plate are located within the annular area enclosed by the projection of the bottom of the heating element on the heating plate, the motor front bracket extends into the space enclosed by the heating element and the heating plate. Thus, with the top connecting part as the starting point, the distance between the connecting bracket and the heating plate is greater than the distance between the first connecting part and the heating plate. The motor is relatively far from the heating plate and the heating element, which helps to avoid excessive heat transfer from the heating plate and the heating element to the motor, and helps to avoid excessive temperature during motor operation. Furthermore, in the front end of the outer casing and the front bracket of the motor, at least the projection of the front bracket of the motor onto the heating plate is located within the annular area enclosed by the projection of the bottom of the heating element onto the heating plate. The front bracket of the motor extends into the space enclosed by the heating element and the heating plate, and the motor will not interfere with the heating element. Therefore, it is beneficial for the motor as a whole to move closer to the heating plate along the axial direction of the motor shaft, thereby reducing the height of the blender along the axial direction of the motor shaft. In the embodiments of this application, the aforementioned positional relationship reduces the height of the cup holder assembly, thereby reducing the height of the mixing cup assembly, and ultimately reducing the height of the blender along the axial direction of the motor shaft.

[0025] In some embodiments, the heating plate includes a plate body and a protrusion protruding into the interior of the stirring cup, the plate body circumferentially surrounding the protrusion; the junction of the connecting frame and the top connecting portion is not lower than the plate body; the top connecting portion extends into the protrusion; the protrusion includes a connecting hole; the blade assembly includes a blade shaft; the blade shaft and the motor shaft are connected through the connecting hole.

[0026] As described above, since the protrusion extends towards the interior of the mixing cup, the intersection of the connecting bracket and the top connecting portion is not lower than the main body of the disc; the top connecting portion extends into the protrusion, which is more conducive to reducing the axial height of the mixing cup assembly along the motor shaft. Furthermore, the extension of the top connecting portion into the protrusion can also help position the motor assembly, making motor assembly convenient.

[0027] In some embodiments, the cup holder assembly includes a heating plate support, the heating plate support including a first mounting portion; the stirring cup assembly includes a connecting arm distributed circumferentially around the motor, the connecting arm being connected to the motor and including a second mounting portion; the cup holder assembly includes a cup holder, the cup holder including a third mounting portion. The third mounting portion, the second mounting portion, and the first mounting portion are assembled together. The stirring cup assembly further includes a shock absorber located between the first mounting portion and the second mounting portion, and between the second mounting portion and the third mounting portion.

[0028] As described above, since the shock absorber is located between the first mounting part and the second mounting part, and between the second mounting part and the third mounting part, the shock absorber helps to reduce the vibration caused by the motor during operation, such as reducing the noise generated by the vibration.

[0029] In some embodiments, the stirring cup assembly satisfies at least one of the following conditions:

[0030] The motor is a DC motor. The axial height of the motor along the motor shaft is L, 30mm≤L≤75mm; the diameter of the motor is w, w≤76.5mm; the load torque of the motor is T, 105N·m≤T≤135N·m; the no-load speed of the motor is V, 12000r / min≤V≤14500r / min; the load speed of the motor is v: 9000r / min≤v≤11000r / min; the height of the cup holder assembly along the axial direction of the motor shaft is k, k≤85mm.

[0031] As described above, the motor meeting at least one of the above conditions helps ensure a low motor height, which in turn results in a low height of the mixing cup assembly along the motor shaft axial direction, further ensuring a low overall height of the mixing cup assembly. When the mixing cup assembly and base are detachably assembled, it also facilitates convenient handling of the mixing cup assembly by the consumer.

[0032] Secondly, this application discloses a food processor. The food processor includes any of the aforementioned mixing cup assembly and base, and the mixing cup assembly and base are detachable and assembleable.

[0033] As described above, the food processor has at least the beneficial effects of the mixing cup assembly. For example, the low height of the mixing cup assembly along the motor shaft will result in a low overall height of the food processor. Attached Figure Description

[0047] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0048] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movements between components in a specific posture (as shown in the attached figures); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.

[0049] See Figure 1 , Figure 3 and Figure 5 This application discloses a food processor. The food processor includes a blending cup assembly 10 and a base 20. The blending cup assembly 10 and the base 20 are detachable (can be understood as a separate structure). In one usage scenario, when food needs to be processed using the food processor, the blending cup assembly 10 is assembled to the base 20. When the processed food needs to be poured out, the blending cup assembly 10 can be removed from the base 20. Alternatively, the blending cup assembly 10 and the base 20 can be a single unit. In one usage scenario, regardless of whether food needs to be poured out, the blending cup assembly 10 and the base 20 are assembled as a single unit, and the blending cup assembly 10 cannot be removed from the base 20. Whether the blending cup assembly 10 and the base 20 are a single unit or separate units, the blending cup assembly includes a blending cup 1, a blade assembly 2, a motor 3, a blade assembly 4, and a cup holder assembly. The blade assembly 2 may or may not have a heating function. When it has a heating function, the blade assembly 2 includes a heating plate 21, a heating element 22, and a heating plate seal 23. The heating element 22 can be a heating tube; regardless of its structure, the heating element 22 only needs to be able to heat the food inside the food processing cavity. The cup holder assembly includes the heating plate support 5 and the cup holder 6, but is not limited to these.

[0050] The cup holder assembly is assembled with the mixing cup 1, and the blade assembly 2 and the mixing cup 1 form a food processing chamber. The aforementioned assembly relationship is not limited; some embodiments are as follows: See Figure 3 , Figure 6 and Figure 7The cup holder assembly includes a heating plate support 5, a heating plate 21, and a heating plate seal 23, both of which include clamping portions 24. The heating plate support 5 is assembled with the stirring cup 1. The assembly method of the heating plate support 5 and the stirring cup 1 is not limited; for example, the heating plate support 5 and the stirring cup 1 can be assembled using a snap-fit ​​structure or a threaded structure. After assembly, the clamping portions 24 clamp between the stirring cup 1 and the heating plate support 5, so that the heating plate 21 and the stirring cup 1 form a cavity. The heating plate seal 23 seals the cavity, thereby forming a food processing chamber with the blade assembly 2 and the stirring cup 1. In other embodiments, the heating plate seal can also be provided on the stirring cup 1. Regardless of the method, as long as the heating plate seal 23 can achieve the aforementioned sealing function, it is acceptable.

[0051] When the heating plate support 5 and the mixing cup 1 are assembled, the cup holder 6 is also assembled with the heating plate support 5. When the cup holder 6 and the mixing cup 1 are assembled, the heating plate support 5 and the cup holder 6 are also assembled, and correspondingly, the blade assembly 2 is clamped between the cup holder 6 and the mixing cup 1. In short, the assembly method of the heating plate support 5, the cup holder 6, and the mixing cup 1 is not limited, as long as the assembly results in the blade assembly 2 and the mixing cup 1 forming a food processing cavity.

[0052] The blade assembly 2 includes a blade located within the food processing chamber. The motor 3 is located within the cup holder assembly and drives the blade to rotate within the food processing chamber.

[0053] The coupler 8 is located within the cup holder assembly and also on the periphery of the motor 3. Figures 2 to 4 The diagram illustrates that coupler 8 is located to the left of motor 3. From the diagram, motor 3 and coupler 8 are roughly side-by-side. Taking the side containing the cup holder assembly as the bottom of each component, the bottom surface 81 of coupler 8 is not lower than the bottom surface of motor 3. Figure 3 The height difference between the two is shown as y.

[0054] In some implementations, the coupler is located below the motor 3, such that the height of the cup holder assembly along the axial direction of the motor shaft 33 is related to the height of the coupler and the height of the motor, for example, at least equal to the sum of the height of the coupler and the height of the motor, or equal to a portion of the height of the coupler and the height of the motor.

[0055] As described above, since the coupler 8 is located inside the cup holder assembly and also on the periphery of the motor 3, and the bottom surface 81 of the coupler is not lower than the bottom surface of the motor, the height of the cup holder assembly no longer includes the height of the coupler 8. Therefore, the height of the cup holder assembly along the axial direction of the motor shaft 33 is relatively low, which makes the height of the stirring cup assembly 10 relatively low. This makes it convenient for consumers to use the stirring cup assembly 10, for example, it is convenient to take it off and put it on from the base 20.

[0056] See Figure 3The height difference between the bottom surface 81 of the coupler and the bottom surface of the motor is y, where 0mm ≤ y ≤ 5mm. For example, 0mm, 0.3mm, 0.5mm, 0.8mm, 1mm, 1.3mm, 1.5mm, 1.8mm, 2mm, 2.3mm, 2.5mm, 2.8mm, 3mm, 3.3mm, 3.5mm, 3.8mm, 4mm, 4.3mm, 4.5mm, 4.8mm, or 5mm.

[0057] As set up above, since 0mm≤y≤5mm, it is further ensured that the height of the cup holder assembly no longer includes the height of the coupler 8. Therefore, the height of the cup holder assembly along the axial direction of the motor shaft 33 is low, which makes the height of the mixing cup assembly 10 low and convenient for consumers to use the mixing cup assembly.

[0058] See Figure 3 and Figure 4 The blade assembly 2 includes a heating plate 21 for forming the food processing chamber and a heating element 22 disposed on the heating plate 21. The heating element 22 includes a bottom portion of the heating plate opposite to the heating plate 21. Along the axial direction of the motor shaft 33 of the motor 3, the top surface 82 of the coupler 8 is lower than the bottom portion of the heating element, and the distance between the top surface 82 of the coupler and the bottom portion of the heating element is n, 10mm≤n≤75mm, for example, 10mm, 15mm, 20mm, 23mm, 28mm, 30mm, 33mm, 35mm, 38mm, 40mm, 43mm, 45mm, 48mm, 50mm, 55mm, 58mm, 60mm, 63mm, 65mm, 68mm, 70mm, 72mm, or 75mm.

[0059] As described above, since 10mm≤n≤75mm, and the bottom surface 81 of the coupler 8 is not lower than the bottom surface of the motor 3, the height of the cup holder assembly along the axial direction of the motor shaft 33 is relatively low, which makes the height of the stirring cup assembly 10 relatively low and convenient for consumers to use.

[0060] See Figure 3 and Figure 13 The blade assembly 2 includes a heating plate 21 and a heating element 22 disposed on the heating plate 21. The heating element 22 includes a cold end 221 and a hot end 222. The cold end 221 includes a terminal 2211. The temperature of the cold end 221 is usually lower than the temperature of the hot end 222; the specific location may vary depending on the temperature difference. Figure 13 The left side of the dashed line represents the cold end 221, and the right side represents the hot end 222. The coupler 8 is located below the cold end 221.

[0061] As described above, since the cold end 221 includes a terminal 2211 and the coupler 8 is located below the cold end 221, it facilitates the connection between the heating plate 21 and the coupler 8. In addition, since the temperature of the cold end 221 is usually lower than that of the hot end, the coupler 8 being located below the cold end 221 allows the coupler 8 to avoid areas with relatively high temperatures. Therefore, the above design reduces the heat transfer from the cutter head assembly 2 to the coupler 8.

[0062] See Figure 4 The cup holder assembly includes a cup holder 6. The cup holder 6 includes a bottom, and the bottom includes a mounting opening 61. The side of the coupler 8 includes a slot 83. The structure of the slot 83 is not limited. Figure 4 In the middle, the slot 83 is L-shaped. The slot 83 is engaged with the side wall 611 of the mounting port 61.

[0063] As described above, the coupler 8 is secured to the side wall 611 of the mounting port 61 via the slot 83, which facilitates the assembly of the coupler 8 and also helps prevent the coupler 8 from shaking.

[0064] See Figures 5 to 7 as well as Figure 3 The motor 3 includes a front motor bracket 32 ​​and a motor shaft 33. The structure of the front motor bracket 32 ​​is not limited to that shown below. Figure 8 The cover-like structure shown, for example, the motor front bracket 32 ​​can also be a tripod, quadruped, or a frame structure. The motor shaft 33 is rotatably connected to the motor front bracket 32 ​​and also connected to the blade assembly 4 mounted on the blade assembly 2. In this way, the motor 3 can drive the blade of the blade assembly 4 to rotate within the food processing chamber. The motor front bracket 32 ​​extends into the space 220 enclosed by the heating plate 21 and the heating element 22. The motor 3 is assembled with the cup holder assembly, and it is not limited to any specific component of the cup holder assembly. For example, the cup holder assembly includes a heating plate bracket 5 and a cup holder 6. The motor 3 can be assembled with at least one of the heating plate bracket 5 and the cup holder 6, as long as it is not assembled with the blade assembly 2.

[0065] In some embodiments, a mounting post protrudes from the heating plate or heating element towards the motor 3, and the motor is connected to the mounting post. Considering motor stability, the distance between the mounting post and the heating plate is greater than the distance between the heating element and the heating plate. Therefore, this arrangement results in a higher height of the cup holder assembly along the motor shaft, which in turn leads to a higher height of the mixing cup assembly 10 along the motor shaft 33, thus making the food processor taller.

[0066] As described above, since the motor 3 is assembled with the cup holder assembly instead of the blade assembly 2, and the motor front bracket 32 ​​extends into the space 220 formed by the heating element 22 and the heating plate 21, this application eliminates the need for a mounting post compared to mounting the motor to a post where the heating plate or heating element protrudes from the mounting post. Therefore, the distance between the motor 3 and the heating plate 21 along the axial direction of the motor shaft 33 is shorter, and the height of the mixing cup assembly 10 is lower, making it easier to remove and place from the base 20. Furthermore, assembling the motor 3 with the cup holder assembly, compared to mounting the motor 3 to the heating plate 21 or the heating element 22 via a mounting post, has several advantages. First, because the motor 3 is not assembled with the mounting post of the blade assembly 2, it helps prevent heat from the blade assembly 2 from being transferred to the motor 3 through the mounting post and corresponding screws. Second, because the motor is not assembled with the blade assembly, the vibration of the motor 3 will not cause vibration of the heating plate 21, thus preventing poor sealing between the blade assembly 2 and the mixing cup 1 (e.g., loosening of the heating plate seal 23 leading to poor sealing), and avoiding leakage from the food processing chamber.

[0067] See Figure 3 , Figures 5 to 7 The cup holder assembly includes a heating plate bracket 5, which includes a heat insulation portion 51. The heat insulation portion 51 includes a bracket opening 50 extending axially through the motor shaft 33. The motor front bracket 32 ​​passes through the bracket opening 50 of the heating plate bracket 5, thereby extending into the space 220 formed by the heating plate 21 and the heating element 22. Those skilled in the art will understand that, even without the heating plate bracket 5, the motor front bracket 32 ​​can still extend into the space 220. In some embodiments, the motor front bracket 32 ​​and the front end 311 of the motor 3's housing can both extend into the space 220. The shape of the bracket opening 50 is not limited, as long as it allows the motor front bracket 32 ​​to pass through. The heat insulation portion 51 is located between the heating element 22 and the motor front bracket 32; or, the heat insulation portion 51 is located between the heating element 22 and the motor front bracket 32, and between the heating plate 21 and the motor front bracket 32.

[0068] As described above, by setting the heat insulation part 51, the motor front bracket 32 ​​passing through the bracket opening 50, and the positional relationship between the heat insulation part 51 and the heating element 22 and heating plate 21, the heat insulation part 51 can isolate heat, further helping to prevent excessive heat from the heating plate 21 and heating element 22 from being transferred to the motor 3, and helping to prevent the motor 3 from overheating during operation. In addition, in some embodiments, the heating plate bracket 5 and the heating plate 21 form a cavity, and the heating element 22 is located in the enclosed space. The heating plate bracket 5 includes a cover plate facing the heating plate 21, and the motor 3 is assembled on the cover plate. In this way, the height between the motor and the heating plate includes at least the sum of the axial distance between the cover plate and the heating plate along the motor shaft, the thickness of the cover plate, and the thickness of the nut, making the axial distance between the motor 3 and the heating plate 21 along the motor shaft 33 relatively large. This results in a relatively high height of the food processor along the motor shaft 33, making it inconvenient for consumers to use the food processor. Compared with the aforementioned embodiments, the motor front bracket 32 ​​passes through the bracket opening 50 of the heating plate bracket 5, and the height of the cup holder assembly is reduced by at least the thickness of the cover plate and the thickness of the related connecting parts. Therefore, the distance between the motor 3 and the heating plate 21 along the axial direction of the motor shaft 33 is closer, which is beneficial to reducing the height of the cup holder assembly along the axial direction of the motor shaft 33. In turn, it is beneficial to reduce the height of the mixing cup assembly 10 along the axial direction of the motor shaft 33, making it more convenient for consumers to use the food processor.

[0069] See Figure 3 , 6 to Figure 8 as well as Figure 10 The motor front bracket 32 ​​includes a top connecting portion 321 and a connecting frame 322 connected to the top connecting portion 321. In some embodiments, the motor front bracket 32 ​​also includes a bottom connecting portion 323. The bottom connecting portion 323 is the part of the motor front bracket 32 ​​used for connecting to the motor housing, and its structure is not limited. The top connecting portion 321 is rotatably connected to the motor shaft 33. The method of rotatable connection is not limited; for example, see [reference needed]. Figure 10 The connecting part 321 includes a bearing mounting cavity, in which a bearing 3211 is installed. The motor shaft 33 passes through the bearing 3211 to achieve the rotatable connection. The motor shaft 33 is also connected to the blade assembly 4; the connection method is not limited. For example, the motor shaft 33 passes through the top connecting part 321 and the heating plate 21 before connecting to the blade assembly 4. The front end 311 of the motor housing 31 is connected to the bottom connecting part 323 to connect the motor housing 31 to the front motor bracket 32. The motor housing 31 is in... Figure 8 and Figure 9The outer casing is cylindrical with a continuous shaft. In this case, the front end of the outer casing is the forward section of the motor casing 31. Alternatively, the motor casing 31 can also be roughly convex in shape, in which case the front end 311 is the narrow part of the convex shape. Those skilled in the art will understand that the length of the front end 311 is not limited and can be determined according to the installation requirements between the motor 3 and the cutter head assembly 2. The connection between the front end 311 and the bottom connecting part 323 can be achieved by clamping as described later, or by connecting with screws or other fasteners. In other embodiments, the motor casing 31 and the motor front bracket 32 ​​are integrally formed and connected. The motor front bracket 32 ​​is not limited to being connected to the motor casing 31.

[0070] See Figure 3 , Figure 6 , Figure 7 and Figure 12 The heating element 22 includes a bottom portion facing away from the heating plate 21. The projection of the bottom portion of the heating element onto the heating plate 21 forms an annular region. In other words, the heating element 22 is annular, such that its bottom portion forms the annular region on the heating plate 21. Thus, along a direction perpendicular to the motor shaft 33, the distance between the outer surface of the motor housing 31 and the heating element 22 is H (e.g., ...). Figure 2 , Figure 3 , Figure 7 and Figure 12 As shown), H≥0. In some embodiments, the radius of the motor 3 is R, 0≤H≤R / 3. The heating element 22 is annular, which can be a C-shaped ring formed by an arc or a ring formed by a curve. The ring can be closed or open. The projection of the front end of the outer shell 311 and the front bracket of the motor 32 as a whole onto the heating plate 21 is located within the annular area. It can be understood by those skilled in the art that it is also possible that only the projection of the front bracket of the motor 32 onto the heating plate 21 is located within the annular area enclosed by the projection of the bottom of the heating element onto the heating plate 21. The front bracket of the motor 32 extends into the space 220 enclosed by the heating element 22 and the heating plate 21. That is, of the front end of the outer shell 311 and the front bracket of the motor 32, at least the front bracket of the motor 32 extends into the space enclosed by the heating element 22 and the heating plate 21. The distance between the connecting bracket 322 and the heating plate 21 along the axial direction of the motor shaft 33 increases radially toward the heating element 22 (see direction). Figure 3 , Figure 6 and Figure 7 (As shown by the middle arrows F1 and F2). For example, see... Figure 7 Along the direction indicated by arrow F1, the distance d2 is greater than d1. (See also...) Figure 12 Along the direction indicated by arrows F1 or F2, the distance d2 is greater than d1. This increase could be... Figure 12 As shown, the distance between the connecting frame 322 and the heating plate 21 along the axial direction of the motor shaft 33 increases in a stepped manner in the radial direction of the motor shaft 33 toward the heating element 22. For example, the connecting frame 322 includes multiple steps. Figure 12 The diagram illustrates two steps, designated as the first step 3212 and the second step 3213 for easy distinction. The steps further away from the heating plate 21 have a wider width in the direction perpendicular to the motor shaft 33. Figure 12 In this configuration, the first step 3212 is farther from the heating plate 21 than the second step 3213, and the first step 3212 is wider than the second step 3213. Furthermore, besides the aforementioned step changes and the gradual increase described later, the increase can also be that the distance on one side increases more than the distance on the other side; for example, the connecting frame may be trapezoidal. To achieve this increase, the connecting frame 322 includes a first segment and a second segment. The first segment is connected to the top connecting portion and is parallel to the heating plate 21. The second segment is inclined downwards relative to the first segment and connected to the motor housing 31. The width of the projection of the second segment onto the heating plate 21 is greater than the width of the projection of the first segment onto the heating plate.

[0071] In some food processors, the connecting bracket 322 includes a first connecting portion and two second connecting portions. The first connecting portion is parallel to the heating plate, thus the distance between the first connecting portion and the heating plate support is equidistant everywhere. Typically, the length of the first connecting portion is at least half the diameter of the motor. Each of the opposite ends of the first connecting portion is connected to one of the second connecting portions; the second connecting portions are connected to the bottom connecting portion 323, for example, the second connecting portions are perpendicular to the heating plate. In this case, the motor front bracket 32 ​​also extends into the space 220 enclosed by the heating plate 21 and the heating element 22, and the motor 3 also satisfies the aforementioned relationship.

[0072] As described above, since the distance between the connecting bracket 322 and the heating plate 21 along the axial direction of the motor shaft 33 increases in the radial direction of the motor shaft 33 toward the heating element 22, and the projection of at least the front motor bracket 32 ​​on the heating plate 21 is located within the annular area enclosed by the projection of the bottom of the heating element on the heating plate, the front motor bracket extends into the space 220 enclosed by the heating element and the heating plate. Thus, with the top connecting portion 321 as the starting point, the distance between the connecting bracket 322 and the heating plate 21 is greater than the distance between the first connecting portion and the heating plate 21. The motor 3 is relatively far from the heating plate 21 and the heating element 22, which helps to avoid excessive heat transfer from the heating plate 21 and the heating element 22 to the motor 3, and helps to avoid the motor 3 from overheating during operation. Furthermore, in the outer casing front end 311 and the motor front bracket 32, at least the projection of the motor front bracket 32 ​​on the heating plate 21 is located within the annular area enclosed by the projection of the bottom of the heating element on the heating plate. The motor front bracket 32 ​​extends into the space 220 enclosed by the heating element 22 and the heating plate 21, and the motor 3 will not interfere with the heating element 22. Therefore, it is beneficial for the motor 3 to move closer to the heating plate 21 along the axial direction of the motor shaft 33, thereby reducing the height of the food processor along the axial direction of the motor shaft 33. In the embodiments of this application, the aforementioned positional relationship reduces the height of the cup holder assembly (such as...). Figure 6 The height of k) shown is reduced, thereby lowering the height of the mixing cup assembly 10, and ultimately reducing the axial height of the food processor along the motor shaft 33.

[0073] In other embodiments, at least the projection of the motor front bracket 32 ​​onto the heating plate 21 may be located outside the annular area enclosed by the projections of the heating element 22 onto the heating plate 21. In this case, at least the motor front bracket 32 ​​extends into the space 220 enclosed by the heating plate 21 and the heating element 22. In this embodiment, the motor front bracket 32 ​​extends into the space 220 enclosed by the heating element 22 and the heating plate 21, and the motor 3 will not interfere with the heating element 22. Therefore, it is beneficial for the motor 3 to move closer to the heating plate 21 along the axial direction of the motor shaft 33, thereby reducing the height of the food processor along the axial direction of the motor shaft 33. In the embodiments of this application, the aforementioned positional relationship reduces the height of the cup holder assembly (e.g., Figure 6 The height of k) shown is reduced, thereby lowering the height of the mixing cup assembly 10, and ultimately reducing the axial height of the food processor along the motor shaft 33.

[0074] In some embodiments, the connecting frame 322 includes a support sidewall. The support sidewall is shaped like a frustum or a truncated pyramid. Thus, the distance between the connecting frame 322 and the heating plate 21 gradually increases along the axial direction of the motor shaft 33, thereby increasing the distance radially toward the heating element 22 along the motor shaft 33. Figure 3 and Figure 7 As shown, the maximum distance between the connecting bracket 322 and the heating plate 21 along the axial direction of the motor shaft 33 is d, 5mm≤d≤25mm, for example, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm, 19mm, 20mm, 21mm, 22mm, 23mm, 24mm or 25mm.

[0075] In some implementations, the connecting frame includes a first section and a second section. The first section is parallel to the motor shaft 33, and the second section is perpendicular to the motor shaft 33. That is, the first section and the second section form an L-shape. In this way, based on safety regulations and other considerations, the internal components of the motor need to be moved down (for example, the enameled wire needs to be a certain distance from the second section), resulting in a larger height of the motor itself. Consequently, the height of the food processor along the axial direction of the motor shaft is larger.

[0076] As described above, because the sidewalls of the bracket are shaped like a frustum or a truncated cone, the distance between the connecting frame 322 and the heating plate 21 along the axial direction of the motor shaft 33 gradually increases. This allows for the assembly of motor components (such as enameled wire) inside the connecting frame 322, meaning the internal components do not need to be lowered, and it also provides greater electrical clearance. Therefore, the motor itself is shorter (for example, shorter than the L-shaped motor formed by the first and second sections of the aforementioned motor front bracket), which helps to reduce the height of the stirring cup assembly along the axial direction of the motor shaft 33. Of course, this design also helps to prevent excessive heat transfer from the heating plate assembly 2 to the motor 3.

[0077] See Figure 10 The angle between the side wall of the bracket and the plane perpendicular to the motor shaft 33 is α, where 110 degrees ≤ α ≤ 150 degrees, for example, 110 degrees, 112 degrees, 115 degrees, 118 degrees, 120 degrees, 123 degrees, 125 degrees, 128 degrees, 130 degrees, 133 degrees, 135 degrees, 138 degrees, 140 degrees, 143 degrees, 145 degrees, 148 degrees, 149 degrees, or 150 degrees.

[0078] As described above, since 110 degrees ≤ a ≤ 150 degrees, the height of the connecting bracket 322 in the axial direction of the motor shaft 33 is relatively low. This design helps to prevent excessive heat from the blade assembly 2 from being transferred to the motor 3, and also helps to reduce the height of the food processor along the axial direction of the motor shaft 33.

[0079] See Figure 6 The heating plate 21 includes a plate body 211 and a protrusion 212 protruding into the stirring cup 1. The plate body 211 surrounds the protrusion 212. The intersection of the connecting bracket 322 and the top connecting portion 321 is not lower than the plate body 211. Figure 6 The height difference is shown as p. The top connecting part 321 extends into the protrusion 212, and the top connecting part 321 includes a top cavity that can accommodate an oil seal, etc. The protrusion 212 includes a connecting hole. The cutter assembly includes a cutter shaft. The cutter shaft and the motor shaft 33 are connected through the connecting hole. Figure 5 The diagram shows the motor shaft 33 passing through the connecting hole and connecting to the cutter shaft of the cutter assembly. Alternatively, the cutter shaft could pass through the connecting hole and connect to the motor shaft 33. The connection between the cutter shaft and the motor shaft 33 via the connecting hole includes the case where the cutter shaft and the motor shaft 33 are integrally constructed.

[0080] As described above, since the protrusion 212 protrudes into the interior of the mixing cup 1, the intersection of the connecting bracket 322 and the top connecting part 321 is not lower than the main body 211 of the disc; the top connecting part 321 extends into the protrusion 212, which is more conducive to reducing the axial height of the mixing cup assembly along the motor shaft.

[0081] In some embodiments, the heating plate support 5 includes a first mounting portion 52. The food processor includes connecting arms 35 distributed circumferentially around the motor 3. The connecting arms 35 can be connected to the motor housing 31 of the motor 3, or as... Figure 9 , Figure 10 and Figure 11As shown, the connecting arm 35 is also connected to the motor rear bracket 34. This connection can be either an integral part of the connecting arm 35 and the motor 3, or the connecting arm 35 can be assembled as a separate component onto the motor 3. The number of connecting arms 35 is not limited to four; it can be five or three, etc. The connecting arm 35 includes a second mounting portion 352. The cup holder 6 includes a third mounting portion 62. The third mounting portion 62, the second mounting portion 352, and the first mounting portion 52 are assembled together, and their assembly is not limited to the bolt and locking mechanism described later. The structures of the first mounting portion 52, the second mounting portion 352, and the third mounting portion 62 are not limited, as long as they enable assembly between the heating plate bracket 5, the cup holder 6, and the motor 3. The food processor includes a shock absorber 7, which is located between the first mounting portion 52 and the second mounting portion 352, and between the second mounting portion 352 and the third mounting portion 62, thereby enabling assembly of the motor 3 with the heating plate bracket 5 and the cup holder 6. Of course, the motor 3 can be assembled with the heating plate bracket 5 or the cup holder 6. Based on the function of the shock absorber 7, the number of shock absorbers 7 can be one, as shown in the figure, in an I-shape, including a base and shock-absorbing pads located at both ends of the base. One shock-absorbing pad is located between the first mounting part 52 and the second mounting part 352, and the other shock-absorbing pad is located between the second mounting part 352 and the third mounting part 62. The number of shock absorbers 7 can also be two, in which case the assembly relationship between the shock absorber 7 and the aforementioned mounting parts is the same as the assembly relationship between the shock-absorbing pads and the mounting parts.

[0082] As described above, since the shock absorber 7 is located between the first mounting part 52 and the second mounting part 352, and between the second mounting part 352 and the third mounting part 62, the shock absorber 7 is beneficial to reduce the vibration caused by the operation of the motor 3, for example, it is beneficial to reduce the noise caused by the vibration.

[0083] In addition, the following describes one method of assembling an electric motor:

[0084] See Figure 3 , Figure 8 , Figure 9 and Figure 11 The front motor bracket 32 ​​and the rear motor bracket 34 are each provided with mounting holes 320. Bolts pass through the mounting holes 320 and, together with locking components (such as nuts or screws), secure the front motor bracket 32 ​​and the rear motor bracket 34. After securing, the motor housing 31 is clamped between the front motor bracket 32 ​​and the rear motor bracket 34. As described above, because the front motor bracket 32 ​​and the rear motor bracket 34 are secured together, the assembly of the motor 3 is simple and convenient.

[0085] See Figure 8, Figure 9 and Figure 11 The motor housing 31 forms a bottom opening. The motor rear bracket 34 covers the bottom opening. The connecting arms 35 (all or part of them) include a first connecting arm 353 and a second connecting arm 354. The first connecting arm 353 extends along the motor rear bracket 34. The second connecting arm 354 contacts the motor housing 31 and extends axially along the motor shaft 33. The contact can be between the second connecting arm 354 and the outer surface of the motor housing 31, or it can be embedded within the motor housing 31. The second connecting arm 354 is connected to the second mounting portion 352. In some embodiments, both the motor rear bracket and the connecting arms are made of plastic.

[0086] As described above, the first connecting arm extends along the rear bracket of the motor, and the second connecting arm extends along the motor housing. This makes it easy to assemble the motor, the rear bracket of the motor, and the connecting arm bracket. The structure of the connecting arm, along with the rear bracket of the motor and the connecting arm, are all made of plastic, which is easy to manufacture and has low cost.

[0087] See Figure 8 and Figure 9 The connecting arm 35 is provided with reinforcing ribs 355. The reinforcing ribs 355 are spaced apart in the width direction of the connecting arm 35. Although Figure 9 Only one reinforcing rib 355 perpendicular to the length direction of the connecting arm 35 is shown in the figure. Those skilled in the art will understand that the reinforcing rib 355 may also be spaced apart along the length direction of the connecting arm 35. In other embodiments, the reinforcing ribs 355 may be spaced apart only along the length direction of the connecting arm 35, or only along the width direction of the connecting arm 35. The figure shows that the length of the reinforcing rib 355 is equal to the length of the connecting arm 35, but the length of the reinforcing rib 355 may also be shorter than the length of the connecting arm 35.

[0088] As described above, by providing reinforcing ribs 355 on the connecting arm 35, and by providing reinforcing ribs 355 at intervals in the width direction and / or length direction of the connecting arm 35, the reinforcing ribs 355 can enhance the strength of the connecting arm 35, and can better assemble the motor 3 with the heating plate bracket 5 and the cup holder 6.

[0089] See Figure 9 and Figure 11The motor rear support 34 includes a flat support body 341 and a gathering portion 342 protruding from the support body 341. The gathering portion 342 may also be flat (as shown in the figure, a circular plate; the flatness can be understood as the support body 341 or the gathering portion including relatively parallel planes, such as cylinders, etc.). Of course, the gathering portion 342 may be small and not flat, as long as it does not significantly affect the height. The support body 341 may or may not be circular, and its shape is determined by the shape of the bottom opening of the motor housing 31. The support body 341 covers the bottom opening. All connecting arms 35 converge at the gathering portion 342. In some embodiments, the gathering portion 342 is not part of the motor rear support 34; that is, the food processor includes a mounting frame, which includes the gathering portion 342 and multiple connecting arms 35, which converge at the gathering portion 342, and the motor rear support 34 is supported by the mounting frame.

[0090] As described above, since the motor rear bracket 34 includes a bracket body 341 and a gathering part 342, and the height of the motor rear bracket 34 is the sum of the thickness of the bracket body 341 and the height of the gathering part 342, the height is relatively low. Therefore, the motor rear bracket 34 with this structure, after being assembled with the motor housing 31, also helps to reduce the height of the food processor along the axial direction of the motor shaft 33.

[0091] See Figure 7 The first mounting portion 52 is columnar. The third mounting portion 62 is also columnar and has a positioning groove. The first mounting portion 52 passes through the second mounting portion 352 and is located within the positioning groove. Those skilled in the art will understand that when the first mounting portion 52 has a positioning groove, the third mounting portion 62 is located within the positioning groove. Screws are inserted into the third mounting portion 62, the second mounting portion 352, and the first mounting portion 52 to assemble the heating plate bracket 5, the cup holder 6, and the connecting arm 35 together. In other embodiments, the first mounting portion 52 has a positioning groove; in this case, the first mounting portion 52 may also pass through the second mounting portion 352, and the third mounting portion 62 may be located within the positioning groove. In the above embodiments, the first mounting portion 52 passes through the second mounting portion 352; in other embodiments, the third mounting portion 62 may also pass through the second mounting portion 352.

[0092] As described above, since one of the first mounting part 52 and the third mounting part 62 includes a positioning groove; the other of the first mounting part 52 and the third mounting part 62 passes through the second mounting part 352 and is located in the positioning groove, the assembly of the heating plate bracket 5, the cup holder 6 and the connecting arm 35 is simple and precise through this positioning.

[0093] See Figure 10Along the axial direction of the motor shaft 33, the sum of the height of the motor housing 31 and the height of the motor rear bracket 34 is F, and the height of the second mounting part 352 relative to the motor rear bracket 34 is f, where 1 / 2 ≤ f / F ≤ 1.

[0094] As described above, since 1 / 2≤f / F≤1, and considering the circumferential distribution of the connecting arm 35 in the motor 3, this ensures that the motor 3 is less prone to shaking during operation, making the motor 3 more stable.

[0095] See Figure 7 The heating plate support 5 includes an abutment surface 53. The structure of the abutment surface 53 is not limited; it can abut against the blade assembly 1 to clamp the bottom of the mixing cup 1, thus clamping the blade assembly 2. For example, the heating plate support 5 may be recessed into a U-shape away from the mixing cup 1. The abutment surface 53 is the bottom surface of the U-shape. The edge of the blade assembly 2 includes a clamping portion 24. In some embodiments, the clamping portion 24 is located at the edge of the heating plate seal 23 and the edge of the heating plate 21. In other embodiments, the clamping portion 24 may be located only at the edge of the heating plate 21, or at the edge of the heating plate seal 23. The clamping portion 24 is clamped between the mixing cup 1 and the abutment surface 53. The motor 3 includes a motor housing 31, and the top surface of the motor housing 31 is not lower than the abutment surface 53. Figure 7 The height difference between the top surface and the contact surface 53 is shown as m. It is not less than, meaning m is greater than or equal to 0.

[0096] As described above, since the top surface of the motor housing 31 is not lower than the contact surface 53, and the contact surface 53 and the mixing cup 1 clamp the edge of the blade assembly 2, the distance between the motor 3 and the blade assembly 2 is relatively close, which helps to reduce the height of the food processor along the axial direction of the motor shaft 33.

[0097] In some embodiments, the motor housing 31 is through-hole shaped and includes two opposing openings (a front opening and a rear opening), and both the front motor bracket 32 ​​and the rear motor bracket 34 are cover-shaped. The front motor bracket 32 ​​and the rear motor bracket 34 each cover one of the openings. The motor 3 includes a fan (not shown) connected to the motor shaft 33. At least one of the front motor bracket 32, the rear motor bracket 34, and the motor housing 31 is provided with a through hole 310, which connects the interior and exterior of the motor 3. Figure 8 The diagram shows that both the front bracket 32 ​​of the motor and the housing 31 of the motor are provided with the through hole 310.

[0098] As described above, by providing the through hole 310, which connects the interior and exterior of the motor 3, the fan rotation can dissipate heat from inside the motor 3 through the through hole 310 to the exterior, thus helping to prevent the motor 3 from overheating during operation. Simultaneously, carbon dust generated by the motor 3 can also be discharged to the exterior through the through hole 310. Furthermore, the front motor bracket 32 ​​and the rear motor bracket 34 are cover-shaped. On one hand, the front motor bracket 32 ​​and the rear motor bracket 34 are individually strong; on the other hand, the cover-shaped design of the front motor bracket 32 ​​and the rear motor bracket 34 also helps to prevent liquids such as water from entering the interior of the motor 3.

[0099] The stirring cup assembly 10 satisfies at least one of the following conditions:

[0100] The motor 3 is a DC motor (brushed DC motor or brushless DC motor). As described above, under the same performance, the axial length of a DC motor is usually shorter than that of a series motor. Combined with the aforementioned positional relationship between the motor 3 and the blade assembly 2, it is more conducive to reducing the height of the food processor along the motor shaft 33 axial direction.

[0101] The height of the motor along the axial direction of the motor shaft is L, 30mm≤L≤75mm; the diameter of the motor is w, w≤76.5mm; the load torque of the motor is T, 105N·m≤T≤135N·m; the no-load speed of the motor is V, 12000r / min≤V≤14500r / min; the load speed of the motor is v: 9000r / min≤v≤11000r / min; the height of the cup holder assembly along the axial direction of the motor shaft is k, k≤85mm (e.g. Figure 3 and Figure 6 (As shown).

[0102] As described above, the motor 3 satisfies at least one of the above conditions, which helps to ensure that the height of the motor 3 is low. Consequently, the height of the mixing cup assembly 10 along the axial direction of the motor shaft 33 is also low, further ensuring that the height of the mixing cup assembly 10 is low. When the mixing cup assembly 10 and the base 20 are detachably assembled, it also facilitates convenient handling of the mixing cup assembly by the consumer.

[0103] On the other hand, this application discloses a food processor, which includes any of the aforementioned mixing cup assembly 10 and base 20, wherein the mixing cup assembly 10 and base 20 are detachable and assembleable.

[0104] As described above, the food processor has at least the beneficial effects of the mixing cup assembly. For example, the low height of the mixing cup assembly along the motor shaft will result in a low overall height of the food processor.

[0105] It should be noted that the technical solutions or features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; all 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.
