Description

Technical Field

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

[0002] The food processor includes a blending cup, a heating plate assembly, a heating plate support, a motor, and a blade assembly. The heating plate assembly and the blending cup form a food processing chamber, including a heating plate and heating elements. The heating plate support and the heating plate form a cavity. The motor shaft is connected to the blade assembly, and the motor drives the blades of the blade assembly to rotate within the food processing chamber, thereby processing the food within the chamber.

[0003] However, technicians have found that existing food processors have a relatively high axial height along the motor shaft, making them inconvenient to use. Utility Model Content

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

[0005] This application discloses a food processor. The food processor includes a blending cup, a heating plate assembly, a motor, a blade assembly, and a cup holder assembly. The cup holder assembly is assembled with the blending cup, and the heating plate assembly and the blending cup form a food processing chamber. The motor is assembled with the cup holder assembly and includes a front motor bracket and a motor shaft; the motor shaft is rotatably connected to the front motor bracket, and the motor shaft drives the blade assembly to rotate. The cup holder assembly includes a heating plate bracket. The heating plate bracket includes a bracket opening extending axially through the motor shaft; the heating plate assembly includes a heating plate and a heating element. The front motor bracket passes through the bracket opening of the heating plate bracket and extends into the space enclosed by the heating element and the heating plate.

[0006] As described above, since the motor is assembled with the cup holder assembly instead of the heating plate assembly, and considering that the motor front bracket passes through the bracket opening of the heating plate bracket and extends into the space enclosed by the heating element and the heating plate, this arrangement reduces the thickness of the cover plate and related connecting parts compared to assembling the motor with the cover plate of the heating plate bracket. Furthermore, compared to mounting the heating plate or heating element with a protruding mounting post and the motor mounted to the mounting post, this application eliminates the need for a mounting post. Therefore, the axial distance between the motor and the heating plate along the motor shaft is shorter, which helps to reduce the height of the food processor along the motor shaft. For a separate mixing cup assembly and base, the mixing cup assembly is shorter and easier to remove from the base, thus making the food processor more convenient for consumers to use. Furthermore, assembling the motor with the cup holder assembly has several advantages. First, compared to assembling the motor with the heating plate or heating element mounting post, assembling the motor separately from the heating plate assembly helps prevent heat from the heating plate assembly from being transferred to the motor through the mounting post and corresponding screws. Second, since the motor is not assembled with the heating plate assembly, the vibration of the motor will not cause the heating plate to vibrate, thus preventing poor sealing between the heating plate assembly and the mixing cup and avoiding water leakage from the food processing chamber.

[0007] In some embodiments, the heating plate support includes a first mounting portion; the motor includes a motor housing and a rear motor support; the food processor includes connecting arms distributed circumferentially around the motor, the connecting arms being connected to the motor housing and / or the rear motor support, and includes 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.

[0008] As described above, the motor is connected to the motor housing and / or the rear motor bracket via a connecting arm. This eliminates the need for a motor connection structure on the front motor bracket, which also helps reduce the axial height of the blender along the motor shaft. Similarly, when the motor is mounted on the cup holder, it further reduces the axial height of the blending cup assembly along the motor shaft.

[0009] In some embodiments, the food processor 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.

[0010] 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.

[0011] In some embodiments, the connecting arm includes a first connecting arm and a second connecting arm; the first connecting arm extends along the rear motor bracket; the second connecting arm contacts the motor housing and extends axially along the motor shaft of the motor, and the second mounting portion is connected to the second connecting arm. And / or, both the rear motor bracket and the connecting arm are made of plastic.

[0012] 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 housing, 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.

[0013] In some embodiments, the connecting arm is provided with reinforcing ribs, which are spaced apart in the width direction and / or length direction of the connecting arm.

[0014] As described above, by providing reinforcing ribs on the connecting arm, and by having the reinforcing ribs spaced apart in the width and / or length directions of the connecting arm, the reinforcing ribs help to enhance the strength of the connecting arm, and can better assemble the motor with the heating plate bracket and cup holder.

[0015] In some embodiments, the motor rear support includes a flat support body and a gathering portion protruding from the disc body; the support body covers the bottom opening formed by the motor housing; all connecting arms converge at the gathering portion; or, the food processor includes a mounting bracket, the mounting bracket includes the connecting arms and the gathering portion, all connecting arms converge at the gathering portion; the motor rear support is flat and supported by the connecting arms.

[0016] As described above, since the rear motor support is flat, its height is the sum of the thickness of the support body and the height of the gathering portion, resulting in a relatively low height. Therefore, this type of rear motor support, when assembled with the motor housing, also helps to reduce the axial height of the food processor along the motor shaft. Of course, the flat shape of the rear motor support and the mounting bracket supporting it also contribute to reducing the axial height of the food processor along the motor shaft.

[0017] In some embodiments, both the first mounting portion and the third mounting portion are columnar, one of the first mounting portion and the third mounting portion includes a positioning groove; the other passes through the second mounting portion and is located within the positioning groove.

[0018] As described above, since one of the first mounting part and the third mounting part includes a positioning groove, and the other of the first mounting part and the third mounting part of the cup passes through the second mounting part and is located in the positioning groove, the assembly of the heating plate bracket, the cup holder and the connecting arm is simple and precise through this positioning.

[0019] In some embodiments, along the axial direction of the motor shaft, the sum of the height of the motor housing and the height of the motor rear bracket is F, and the height of the second mounting portion relative to the motor rear bracket is f, where 1 / 2 ≤ f / F ≤ 1.

[0020] As described above, since 1 / 2≤f / F≤1, combined with the circumferential distribution of the connecting arms on the motor, this ensures that the motor is less prone to shaking during operation, making the motor more stable.

[0021] 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 motor includes a motor housing, and the motor front bracket protrudes toward the heating plate relative to the motor housing. The heating element includes a bottom portion opposite to the heating plate, and the projection of the motor front bracket on the heating plate lies within the annular area enclosed by the projections of the bottom portion of the heating element on the heating plate; or, the projections of the front ends of the motor front bracket and the motor housing on the heating plate lie within the annular area enclosed by the projections of the bottom portion of the heating element on the heating plate.

[0022] As described above, since the projection of the motor front bracket onto the heating plate lies within the annular area enclosed by the projection of the bottom of the heating element onto the heating plate, the motor can avoid the heating element and approach the heating plate. This helps to reduce the distance between the motor and the heating plate, and consequently, reduces the axial height of the food processor along the motor shaft. This feature, combined with the aforementioned gradual increase, not only helps to reduce the axial height of the food processor along the motor shaft but also helps to prevent excessive heat transfer from the heating plate and heating element to the motor. Furthermore, the fact that the projections of the motor front bracket and the front end of the motor housing onto the heating plate lie within the annular area enclosed by the projection of the bottom of the heating element onto the heating plate further reduces the axial height of the food processor along the motor shaft.

[0023] In some embodiments, the distance between the connecting frame and the heating plate along the axial direction of the motor shaft gradually increases in the radial direction of the motor shaft toward the heating element, or varies in a stepwise manner.

[0024] As described above, since the axial distance between the connecting bracket and the heating plate along the motor shaft gradually increases or changes in a stepped manner in the radial direction of the motor shaft towards the heating element, and the projection of at least the front motor bracket on the heating plate is located within the area enclosed by the heating element, the distance between the connecting bracket and the heating plate is greater than the distance between the first connecting portion and the heating plate when both are taken as the starting point. This means the motor is relatively far from the heating plate and the heating element, which helps to prevent excessive heat transfer from the heating plate and the heating element to the motor, thus preventing the motor from overheating during operation. Furthermore, the projection of the front motor bracket on the heating plate is located within the annular area enclosed by the heating element on the heating plate, preventing interference between the motor and the heating element. Therefore, in addition to preventing excessive heat transfer from the heating plate assembly to the motor and avoiding overheating during motor operation, it also helps the motor as a whole move closer to the heating plate along the motor shaft, thereby reducing the height of the blender along 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 motor shaft.

[0025] In some embodiments, the connecting frame includes support sidewalls that are shaped like a frustum or a truncated cone to achieve the gradual increase.

[0026] As described above, because the side walls of the support 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 low in height, which in turn 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. This design also helps prevent excessive heat transfer from the heating plate assembly to the motor.

[0027] 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.

[0028] 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.

[0029] In some embodiments, the heating plate bracket includes a heat insulation portion, the heat insulation portion including the bracket opening; the heat insulation portion is located between the heating element and the front motor bracket; or, the heat insulation portion is located between the heating element and the front motor bracket, and the heat insulation portion is located between the heating plate and the front motor bracket.

[0030] As described above, by setting the heat insulation part, the heat insulation part can isolate heat, which further helps to prevent excessive heat from the heating plate and heating element from being transferred to the motor, and helps to prevent the motor temperature from being too high during operation.

[0031] In some embodiments, the food processor includes at least one of the following features: 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; and the height of the cup holder assembly along the axial direction of the motor shaft is k, k≤85mm.

[0032] As described above, the food processor satisfies at least one of the above features, which can make the cup holder assembly have a lower axial height along the motor shaft, and thus the food processor has a lower height. For example, the motor is a DC motor. 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 and the heating plate assembly, it is more conducive to reducing the axial height of the food processor along the motor shaft.

[0033] In some embodiments, the heating plate support includes an abutment surface; the edge of the heating plate assembly is clamped between the stirring cup and the abutment surface; the motor includes a motor housing, the top surface of which is not lower than the abutment surface.

[0034] As described above, since the top surface of the motor housing is not lower than the contact surface, and the contact surface and the mixing cup clamp the edge of the heating plate assembly, the distance between the motor and the heating plate assembly is relatively close, which helps to reduce the axial height of the food processor along the motor shaft.

[0035] In some embodiments, the food processor includes a blending cup assembly and a base; the blending cup assembly is detachably assembled to the base; the blending cup assembly includes the blending cup, the heating plate assembly, the motor, the blade assembly, and the cup holder assembly.

[0036] As described above, the arrangement between the motor and the heating plate assembly helps to reduce the axial height of the mixing cup assembly along the motor shaft. Furthermore, the mixing cup assembly and the base can be detachably assembled, which makes it easier for consumers to pick up and put down the mixing cup assembly when they need to pour out the food in the mixing cup.

[0048] 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.

[0049] 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.

[0050] See Figure 1 , Figure 2 and Figure 4 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 separate structures). 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. Regardless of whether the blending cup assembly 10 and the base 20 are a single unit or separate structures, the food processor includes a blending cup 1, a heating plate assembly 2, a motor 3, a blade assembly 4, and a cup holder assembly. The cup holder assembly includes a heating plate support 5 and a cup holder 6. The following describes the assembly of motor 3 with at least one of heating plate support 5 and cup holder 6. As can be understood by those skilled in the art, motor 3 can also be assembled with other components of the cup holder assembly besides heating plate support 5 and cup holder 6.

[0051] exist Figure 3 , Figure 5 and Figure 6In this assembly, 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. In one embodiment, after assembly, the heating plate assembly 2 is clamped by the heating plate support 5 and the stirring cup 1. One clamping method is as follows: both the heating plate 21 and the heating plate seal 23 include clamping portions 24, which clamp between the stirring cup 1 and the heating plate support 5. The heating plate assembly 2 and the stirring cup 1 form a food processing cavity. The method of forming the food processing cavity is not limited; for example, the heating plate assembly 2 includes a heating plate 21 and a heating plate seal 23. The heating plate 21 and the stirring cup 1 form a cavity, and the heating plate seal 23 seals the cavity, thereby forming a food processing cavity. In other embodiments, the heating plate seal can also be provided on the stirring cup 1. Regardless of how the heating plate seal is provided, as long as the heating plate seal 23 can achieve the aforementioned sealing function, it is acceptable. In addition, the heating plate assembly 2 also includes a heating element 22. The heating element 22 is used to heat the food in the food processing chamber; for example, the heating element 22 is a heating tube.

[0052] When the heating plate support 5 and the mixing cup 1 are assembled, the cup holder 6 is assembled with the heating plate support 5. When the cup holder 6 and the mixing cup 1 are assembled, the heating plate support 5 is assembled with the cup holder 6, and correspondingly, the heating plate assembly 2 is clamped by 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 heating plate assembly 2 and the mixing cup 1 form a food processing cavity after assembly.

[0053] In the above embodiments, the stirring cup assembly 10 and the base 20 are separate structures, and the cup holder 6 and the heating plate support 5 are components of the cup holder assembly; in the embodiment where the stirring cup assembly 10 and the base 20 are an integral structure, the cup holder 6 and the heating plate support 5 can be integrally formed with the base 20 and are part of the base 20.

[0054] See Figure 3 , Figure 5 and Figure 6 The heating plate bracket 5 includes a bracket opening 50 extending axially through the motor shaft 33 of the motor 3. The shape of the bracket opening 50 is not limited, as long as it allows the front motor bracket 32 ​​to pass through. The motor 3 is assembled with the cup holder assembly, including the front motor bracket 32 ​​and the motor shaft 33. The structure of the front motor bracket 32 ​​is not limited to... Figure 7The cover-like structure shown can be, for example, a tripod, a quadruped, or a frame structure. The motor shaft 33 is rotatably connected to the front motor bracket 32. The motor shaft 33 drives the blade assembly 4 to rotate, thereby enabling the motor 3 to drive the blade of the blade assembly 4 to rotate within the food processing chamber. The front motor bracket 32 ​​passes through the bracket opening 50 of the heating plate bracket 5 and extends into the space 220 formed by the heating element 22 and the heating plate 21.

[0055] In some embodiments, the heating plate support 5 and the heating plate 21 form a cavity, and the heating element 22 is located within the cavity. In this embodiment, the heating plate support 5 includes a cover plate facing the heating plate 21 and used to form the cavity, and the motor 3 is assembled on the cover plate. Thus, 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 large axial distance between the motor 3 and the heating plate 21 along the motor shaft 33, leading to a relatively high height of the food processor along the motor shaft 33, making it inconvenient for consumers to use. In other embodiments, a mounting post protrudes from the heating plate or heating element towards the motor, 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 embodiment also results in a relatively high height of the food processor along the motor shaft. In the case of a separate structure between the mixing cup assembly 10 and the base 20, the two embodiments described above result in a higher height of the cup holder assembly (components consisting of the cup holder 6, heating plate support 5, etc.) of the mixing cup assembly 10, which in turn results in a higher height of the mixing cup assembly 10 along the motor shaft 33, thus making the food processor taller.

[0056] As described above, since the motor 3 is assembled with the cup holder assembly instead of the heating plate assembly 2, and considering that the motor front bracket 32 ​​passes through the bracket opening 50 of the heating plate bracket 5 and extends into the space 220 formed by the heating element 22 and the heating plate 21, this arrangement reduces the thickness of the cover plate and related connecting parts compared to assembling the motor 3 with the cover plate of the heating plate bracket. Furthermore, compared to the heating plate or heating element protruding from the mounting post and the motor being mounted to the mounting post, this application does not require a 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, which helps to reduce the height of the food processor along the axial direction of the motor shaft 33, making it more convenient for consumers to use. Regarding the separate arrangement of the mixing cup assembly 10 and the base 20, the height of the mixing cup assembly 10 is lower, making it easier to remove and place from the base 20.

[0057] Furthermore, assembling the motor 3 with the cup holder assembly has several advantages. Firstly, compared to assembling the motor 3 with the mounting post of the heating plate 21 or the heating element 22, assembling the motor 3 with the mounting post of the heating plate assembly 2 helps to prevent the heat from the heating plate assembly 2 from being transferred to the motor through the mounting post and the corresponding screws. Secondly, since the motor is not assembled with the heating plate assembly 2, the vibration of the motor 3 will not cause the heating plate 21 to vibrate, thus preventing poor sealing between the heating plate assembly 2 and the mixing cup 1 and avoiding water leakage from the food processing chamber.

[0058] See Figure 5 and Figure 6 The food processor includes a motor housing 31 and a rear motor support 34. The assembly of the motor housing 31, the front motor support 32, and the rear motor support 34 is not limited; in some embodiments, see [reference needed]. Figure 3 , Figure 7 , Figure 8 and Figure 10 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.

[0059] The following describes one embodiment of the assembly of the motor 3 with the heating plate support 5 and the cup holder 6: The heating plate support 5 includes a first mounting part 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 or the rear support 34 of the motor 3, or as follows... Figure 8 , Figure 9 and Figure 10 As shown, the connecting arm 35 is also connected to the rear bracket 34 of the motor. 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, three, or other similar components. 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 the assembly of the heating plate bracket 5, the cup holder 6, and the motor 3.

[0060] As described above, the motor is connected to the motor housing 31 and / or the rear motor bracket 34 via the connecting arm 35. This eliminates the need for a motor connection structure on the front motor bracket 32, and also helps reduce the axial height of the blender along the motor shaft. Similarly, when the motor is mounted on the cup holder, it further reduces the axial height of the blending cup assembly along the motor shaft.

[0061] In some embodiments, the food processor includes a shock absorber 7 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 the motor 3 to be assembled with the heating plate support 5 and the cup holder 6. Of course, the motor 3 can be assembled with either the heating plate support 5 or the cup holder 6. Based on the function of the shock absorber 7, there can be one shock absorber 7, which is I-shaped as shown in the figure, including a base and shock-absorbing pads located at both ends of the base. One shock-absorbing pad is located between the first mounting portion 52 and the second mounting portion 352, and the other shock-absorbing pad is located between the second mounting portion 352 and the third mounting portion 62. There can also be two shock absorbers 7, in which case the assembly relationship between the shock absorber 7 and the aforementioned mounting portions is the same as the assembly relationship between the shock-absorbing pads and the mounting portions.

[0062] As described above, since the shock absorber 7 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, the shock absorber 7 helps to reduce vibrations caused by the operation of the motor 3, for example, it helps to reduce noise generated by vibration. Of course, the heating plate bracket 5, the cup holder 6, and the stirring cup 1 are not limited to the above assembly method.

[0063] See Figure 7 , Figure 8 and Figure 10 The connecting arms 35 (all or some of the connecting arms 35) include a first connecting arm 353 and a second connecting arm 354. The first connecting arm 353 extends along the rear motor 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 rear motor bracket and the connecting arms are made of plastic.

[0064] As described above, the first connecting arm 353 extends along the rear motor bracket 34, and the second connecting arm 354 extends along the motor housing 31. In this way, the motor housing 31, the rear motor bracket 34, and the connecting arm bracket are easy to assemble. The structure of the connecting arm is combined with the fact that the rear motor bracket and the connecting arm are both made of plastic, which is easy to manufacture and has low cost.

[0065] See Figure 7 and Figure 8 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 8 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.

[0066] 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.

[0067] See Figure 8 and Figure 10 The 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 can 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 can be small and not flat, as long as it does not significantly affect the height. The support body 341 can be circular or not, 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. As a variation of the above embodiment, the motor rear support 34 may not have the gathering portion 342; that is, the food processor includes a mounting bracket, which includes the connecting arms 35 and the gathering portion 342, with all connecting arms 35 converging at the gathering portion 342; the motor rear support 34 is flat and supported by the connecting arms 35. In the two embodiments described above, the flat shape of the rear motor bracket 34 mainly refers to the fact that the exposed portion of the rear motor bracket after covering the motor housing is flat.

[0068] As described above, since the motor rear support 34 includes a flat support body 341 and a gathering portion 342, and the height of the motor rear support 34 is the sum of the thickness of the support body 341 and the height of the gathering portion 342, resulting in a relatively low height, this structure of the motor rear support 34, when assembled with the motor housing 31, also helps to reduce the axial height of the food processor along the motor shaft 33. Of course, the flat shape of the motor rear support and the implementation of the mounting bracket supporting the motor rear support also contribute to reducing the axial height of the food processor along the motor shaft.

[0069] See Figure 6 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.

[0070] As described above, since one of the first mounting part 52 and the third mounting part 62 includes a positioning groove, and 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.

[0071] See Figure 9 Along 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.

[0072] 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.

[0073] See Figure 3 , Figures 5 to 7 as well as Figure 9The 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 ​​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 9 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. Some embodiments of the connection between the motor housing 31 and the motor front bracket 32 ​​are described below: the front end of the motor housing 31 is connected to the bottom connecting part 323 to achieve the connection between the motor housing 31 and the motor front bracket 32. In other embodiments, the motor housing 31 and the motor front bracket 32 ​​are integrally formed to achieve the connection. The motor front bracket 32 ​​is not limited to being connected to the motor housing 31. The motor housing 31 is in Figure 7 and Figure 8 The 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. As can be understood by those skilled in the art, 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 heating plate 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 connecting parts.

[0074] See Figure 3 , Figure 5 , Figure 6 and Figure 11 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 6 and Figure 11As shown), H≥0. In some embodiments, the radius of the motor 3 is R, 0≤H≤R / 2. 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 enclosed by the projection of the bottom of the heating element. It can be understood by those skilled in the art 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, and the front bracket of the motor 32 extends into the space enclosed by the heating element 22 and the heating plate 21. That is, of the front end of the outer shell and the front bracket of the motor, at least the front bracket of the motor 32 extends into the space enclosed by the heating element 22 and the heating plate 21.

[0075] As described above, since the projection of the motor front bracket onto the heating plate lies within the annular area enclosed by the projection of the bottom of the heating element onto the heating plate, the motor can avoid the heating element and approach the heating plate. This helps to reduce the distance between the motor and the heating plate, and consequently, reduces the axial height of the food processor along the motor shaft. This feature, combined with the aforementioned gradual increase, not only helps to reduce the axial height of the food processor along the motor shaft but also helps to prevent excessive heat transfer from the heating plate and heating element to the motor. Furthermore, the fact that the projections of the motor front bracket and the front end of the motor housing onto the heating plate lie within the annular area enclosed by the projection of the bottom of the heating element onto the heating plate further reduces the axial height of the food processor along the motor shaft.

[0076] In some embodiments, 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 5 and Figure 6 (As shown by the middle arrows F1 and F2). For example, see... Figure 6 Along the direction indicated by arrow F1, the distance d2 is greater than d1. (See also...) Figure 11 Along the direction indicated by arrows F1 or F2, the distance d2 is greater than d1. This increase could be... Figure 11 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 towards the heating element. For example, the connecting frame 322 includes multiple steps. Figure 11 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 11 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.

[0077] 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.

[0078] 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 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, and the motor front bracket extends into the space 220 enclosed by the heating element and the heating plate, thus, with the top connecting part 321 as the starting point, the gradually increasing distance between the first connecting part and the heating plate 21 is equal everywhere. This makes the motor 3 relatively far away 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.

[0079] 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 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 5The 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.

[0080] In summary, this application, while reducing the distance between the motor 3 and the heating plate 21, also helps to prevent excessive heat from the heating plate from being transferred to the motor, thus preventing the motor 3 from overheating during operation.

[0081] 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 from the motor shaft 33 towards the heating element 22. Figure 3 and Figure 6 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.

[0082] 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.

[0083] As described above, because the sidewalls of the bracket are shaped like a frustum or a truncated cone, the distance between the connecting bracket 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 bracket 322, meaning the internal components do not need to be lowered, and it also provides greater electrical clearance. Therefore, the motor itself is relatively low (for example, lower than the height of the L-shaped motor formed by the first and second sections of the aforementioned motor front bracket), which helps to reduce the overall height of the food processor along the motor shaft 33. Of course, this design also helps to prevent excessive heat from the heating plate assembly 2 from being transferred to the motor 3.

[0084] See Figure 9The 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.

[0085] 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 heating plate 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.

[0086] See Figure 5 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 5 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 can 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.

[0087] As described above, since the protrusion 212 protrudes towards the interior of the stirring cup 1, the intersection of the connecting bracket 322 and the top connecting portion 321 is not lower than the main body 211 of the disc; the top connecting portion 321 extends into the protrusion 212, which is more conducive to reducing the axial height of the stirring cup assembly along the motor shaft. In addition, the extension of the top connecting portion 321 into the protrusion 212 can also be used to position the assembly of the motor 3, making the motor assembly convenient.

[0088] See Figure 3 , Figure 5 and Figure 6 The heating plate bracket 5 includes a heat insulation portion 51, which includes the bracket opening 50. 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 the heat insulation portion 51 is also located between the heating plate 21 and the motor front bracket 32.

[0089] As described above, by setting the heat insulation part 51, the heat insulation part 51 can isolate heat, which further helps to prevent excessive heat from the heating plate 21 and the heating element 22 from being transferred to the motor 3, and helps to prevent the motor 3 from getting too hot during operation.

[0090] In some embodiments, the food processor includes at least one of the following features: the motor 3 is a DC motor, a brushed DC motor, or a brushless DC motor. The axial height of the motor along the motor shaft is L, 30mm ≤ L ≤ 75mm, for example, 30mm, 32mm, 35mm, 38mm, 40mm, 43mm, 45mm, 48mm, 50mm, 53mm, 55mm, 57mm, 60mm, 62mm, 65mm, 68mm, 70mm, 72mm, or 75mm, where L is [see details]. Figure 9 As shown. The diameter of motor 3 is w, w≤76.5mm, and the overall height of the bottom of the cup body (which can also be considered as the height of the cup holder assembly, for example, the sum of the height of the cup holder 6 and the height of the heating plate bracket) is k (see...). Figure 5 ), k≤85mm; motor load torque is T, 105N·m≤T≤135N·m; motor no-load speed is V, 12000r / min≤V≤14500r / min; motor load speed is v: 9000r / min≤v≤11000r / min.

[0091] As described above, motor 3 satisfies at least one of the above conditions, which helps ensure that the height of motor 3 is low. Consequently, the height of the blending cup assembly 10 along the axial direction of motor shaft 33 is low (for example, if motor 3 is a DC motor, under the same performance, the axial length of a DC motor is usually shorter than that of a series-wound motor. Combined with the aforementioned positional relationship between motor 3 and heating plate assembly 2, this further helps to reduce the height of the blender along the axial direction of motor shaft 33). This also ensures that the height of blending cup assembly 10 is low. When blending cup assembly 10 and base 20 are detachably assembled, it also facilitates convenient handling of the blending cup assembly by the consumer.

[0092] See Figure 1 , Figure 2 and Figure 4 In some embodiments, the stirring cup assembly 10 is detachably assembled to the base 20; the stirring cup assembly 10 includes the stirring cup 1, the heating plate assembly 2, the motor 3, and the blade assembly 4.

[0093] As described above, in any of the aforementioned embodiments, the arrangement between the motor 3 and the heating plate assembly 2 helps to reduce the height of the mixing cup assembly 10 along the axial direction of the motor shaft 33. Furthermore, the mixing cup assembly 10 and the base 20 can be detachably assembled, which facilitates the consumer's convenient handling of the mixing cup assembly 10 when it is necessary to pour out the food in the mixing cup 1.

[0094] See Figure 6 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 heating plate assembly 1 to clamp the bottom of the stirring cup 1, thus clamping the heating plate assembly 2. For example, the heating plate support 5 may be recessed into a U-shape away from the stirring cup 1. The abutment surface 53 is the bottom surface of the U-shape. The edge of the heating plate 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 stirring 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 6 The height difference between the top surface and the contact surface 53 is shown as m. "Not less than" means m is greater than or equal to 0.

[0095] 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 heating plate assembly 2, the distance between the motor 3 and the heating plate assembly 2 is relatively close, which helps to reduce the height of the food processor along the axial direction of the motor shaft 33.

[0096] 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 7 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.

[0097] 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.

[0098] 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.
