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 jar, a blade assembly, a heating plate assembly, and a motor. The heating plate assembly includes a heating plate and a heating element. The heating plate and the blending jar form a food processing chamber, and the heating element heats the heating plate. The motor shaft is connected to the blade assembly, and the motor drives the blades of the blade assembly to rotate within the blending jar to process the food in the food processing chamber.

[0003] Technicians discovered that the food processor had a relatively high axial height along the motor shaft. Utility Model Content

[0004] The purpose of this application is to disclose a food processor that facilitates reducing the axial height of the food processor along the motor shaft.

[0005] This application discloses a food processor. The food processor includes a heating plate assembly, a motor, and a blade assembly. The heating plate assembly includes a heating plate and a heating element, the heating element including a bottom portion opposite to the heating plate. The motor includes a motor housing, a front motor bracket, and a motor shaft; the front motor bracket is rotatably connected to the motor shaft; the motor is a DC motor, and its axial height along the motor shaft is L, 30mm≤L≤75mm. The projection of the front motor bracket on the heating plate lies within the annular area enclosed by the projection of the bottom portion of the heating element on the heating plate, and the front motor bracket extends into the space enclosed by the heating element and the heating plate.

[0006] As described above, since the projection of the motor front bracket 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 motor can avoid the heating element and approach the heating plate. Furthermore, the motor front bracket extends into the space enclosed by the heating element and the heating plate, which helps reduce the distance between the motor and the heating plate. Moreover, the motor is a DC motor with an axial height L along its shaft, 30mm ≤ L ≤ 75mm, resulting in a relatively low axial height (for example, under normal circumstances, the axial height of a DC motor is lower than that of a series-wound motor for equivalent performance). Therefore, the combination of these features helps reduce the axial 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, thereby reducing the height of the mixing cup assembly, and ultimately reducing the axial height of the blender along the motor shaft, making it more convenient for consumers to use the blender.

[0007] In some embodiments, the motor front bracket includes a top connecting portion and a connecting frame connected to the top connecting portion; the motor shaft is rotatably connected to the top connecting portion and also connected to the blade assembly; the distance between the connecting frame and the heating plate along the axial direction of the motor shaft increases radially toward the heating element.

[0008] As described above, since the axial distance between the connecting bracket and the heating plate along the motor shaft increases radially toward 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, the distance between the connecting bracket and the heating plate is greater than the distance between the first connecting part and the heating plate when both are taken as the starting point. The motor is relatively far away 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 the motor temperature from getting too high during operation.

[0009] In some embodiments, the maximum distance between the connecting frame and the heating plate along the axial direction of the motor shaft is d, where 5mm ≤ d ≤ 25mm.

[0010] As described above, due to the 5mm≤d≤25mm configuration, the space enclosed by the motor front bracket, the heating plate, and the heating element is relatively large (for example, after assembling the motor and cup holder assembly, the space enclosed by the motor front bracket, heating plate, and heating element has no mounting structure, resulting in a larger space). This provides a larger heat dissipation space, which is more conducive to preventing excessive heat transfer from the heating plate assembly to the motor, and helps to prevent the motor from overheating during operation. Furthermore, with 5mm≤d≤25mm, it is also beneficial to reduce the axial height of the food processor along the motor shaft.

[0011] In some embodiments, the axial distance between the connecting frame and the heating plate along the motor shaft gradually increases in the radial direction of the motor shaft toward the heating element.

[0012] As described above, since the distance between the connecting bracket and the heating plate along the axial direction of the motor shaft gradually increases in the radial direction of the motor shaft towards the heating element, the interior of the connecting bracket can accommodate motor components (such as enameled wire) and provide greater electrical clearance. Therefore, the motor itself is low in height, which helps to reduce the height of the mixing cup assembly along the axial direction of the motor shaft, making it convenient for consumers to use the food processor.

[0013] In some embodiments, the food processor includes a blending cup assembled with the heating plate assembly, the heating plate including a plate body and a protrusion projecting toward the interior of the blending cup, the plate body circumferentially surrounding the protrusion; the connecting bracket intersecting the top connecting portion at a point not lower than the plate body; the top connecting portion extending into the protrusion; the protrusion including a connecting hole; the blade assembly including a blade shaft; the blade shaft and the motor shaft connected through the connecting hole.

[0014] 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.

[0015] In some embodiments, the connecting frame includes a support sidewall that is shaped like a frustum or a truncated pyramid.

[0016] In some embodiments, the angle between the sidewall of the bracket and the plane perpendicular to the motor shaft is α, where 110 degrees ≤ α ≤ 150 degrees.

[0017] As described above, since 110 degrees ≤ a ≤ 150 degrees, the height of the connecting bracket along the motor shaft is relatively low. This design helps to prevent excessive heat transfer from the heating plate assembly to the motor and also helps to reduce the height of the food processor along the motor shaft.

[0018] In some embodiments, the distance between the connecting frame and the heating plate along the axial direction of the motor shaft varies in a stepped manner in the radial direction of the motor shaft toward the heating element.

[0019] As described above, since the distance between the connecting frame and the heating plate along the axial direction of the motor shaft changes in a stepped manner in the radial direction of the motor shaft towards the heating element, compared with the first connecting part being parallel to the heating plate, at least part of the connecting frame is at a greater distance from the heating plate than the first connecting part is at a greater distance from the heating plate. This is more conducive to keeping the motor relatively far away 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 the motor temperature from becoming too high during operation.

[0020] In some embodiments, the connecting frame includes multiple steps, with the steps being wider in the direction perpendicular to the motor shaft as they move further away from the heating plate in the axial direction of the motor shaft.

[0021] As described above, since the step further away from the heating plate along the axial direction of the motor shaft is wider in the direction perpendicular to the motor shaft, and the connecting bracket is further away from the heating plate, it is beneficial to avoid excessive heat transfer from the heating plate and heating element to the motor, and to avoid excessively high temperature during motor operation.

[0022] In some embodiments, the motor housing includes a front end connected to the front bracket of the motor, the projection of the front end on the heating plate being located within an annular area enclosed by the projection of the bottom of the heating element on the heating plate, and the front end also extending into the space.

[0023] As described above, since the projection of the front end of the outer casing is also located within the annular area, and the front end of the outer casing also extends into the space, it is beneficial for the motor to have a low axial height, and for the food processor to have a low axial height along the motor shaft.

[0024] In some embodiments, the food processor includes a blending cup and a heating plate support, the heating plate support being assembled with the blending cup, and the heating plate assembly being clamped by the heating plate support and the blending cup; the heating plate support includes a heat insulation portion located between the heating element and the front motor support, or the heat insulation portion located between the heating element and the front motor support and between the heating plate and the front motor support.

[0025] As described above, by setting the heat insulation part, the heat insulation part is located between the heating element and the front bracket of the motor, or the heat insulation part is located between the heating element and the front bracket of the motor and between the heating plate and the front bracket of the motor. In this way, the heat insulation part can isolate heat, which is more conducive to avoiding excessive heat transfer from the heating plate and the heating element to the motor, and helps to avoid the motor temperature from being too high during operation.

[0026] In some embodiments, the food processor includes a cup holder assembly, and the motor is assembled with the cup holder assembly.

[0027] As described above, the motor is assembled with the cup holder assembly. Combined with the aforementioned "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, and the motor front bracket extends into the space enclosed by the heating element and the heating plate," it has no assembly relationship with the heating plate assembly. Compared to the motor being assembled on the cover plate of the heating plate bracket, the above arrangement at least reduces the thickness of the cover plate and the thickness of related connecting parts. Furthermore, compared to the heating plate or heating element protruding from the mounting post, and the motor being installed on the mounting post, this application does not require a mounting post. Therefore, the distance between the motor and the heating plate along the axial direction of the motor shaft is shorter, which helps to reduce the height of the food processor along the axial direction of the motor shaft. 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's mounting post 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 motor's vibration will not cause the heating plate to vibrate, thus preventing poor sealing between the heating plate assembly and the mixing cup (such as loosening of the heating plate seal) and avoiding water leakage from the food processing chamber.

[0028] In some embodiments, the motor includes a rear motor bracket, the front motor bracket and the rear motor bracket are fastened together, and the motor housing is clamped between the front motor bracket and the rear motor bracket.

[0029] As described above, the motor housing is clamped between the front and rear motor brackets, making motor assembly simple and convenient.

[0030] In some embodiments, the motor housing is through-hole and includes two opposing openings; the motor includes a rear motor bracket; the front motor bracket and the rear motor bracket are both cover-shaped, each covering one opening; the motor includes a fan connected to the motor shaft; at least one of the front motor bracket, the rear motor bracket, and the motor housing is provided with a through hole, the through hole connecting the interior and exterior of the motor.

[0031] As described above, by providing the through hole connecting the inside and outside of the motor, the fan rotation can dissipate heat from inside the motor to the outside, thus preventing overheating during operation. Simultaneously, carbon dust generated by the motor can also be discharged to the outside through the through hole. The front and rear motor brackets are cover-shaped; on one hand, the front and rear motor brackets are individually strong, and on the other hand, the cover-shaped design helps prevent water and other liquids from entering the motor.

[0032] In some embodiments, the connecting frame includes a first connecting portion and two second connecting portions; the first connecting portion is parallel to the heating plate, the length of the first connecting portion is at least 1 / 2 of the diameter of the motor, and the opposite ends of the first connecting portion are respectively connected to a second connecting portion; one second connecting portion is connected to the top connecting portion of the front bracket of the motor, and the other second connecting portion is connected to the motor housing.

[0033] 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, and the blade assembly.

[0034] 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.

[0035] In some embodiments, the food processor includes at least one of the following features: the diameter of the motor is w, w≤76.5mm; the motor load torque is T, 105N·m≤T≤135N·m; the motor no-load speed is V, 12000r / min≤V≤14500r / min; the motor load speed is v: 9000r / min≤v≤11000r / min; the mixing cup assembly includes a cup holder assembly, the cup holder assembly includes the motor, and the height of the cup holder assembly along the axial direction of the motor shaft is k, k≤85mm.

[0036] As described above, the food processor meets at least one of the above conditions, which helps ensure a low height for the food processor, and consequently, a low height for the mixing cup assembly along the motor shaft. Furthermore, the detachable assembly of the mixing cup assembly and the base facilitates easy placement and removal of the mixing cup assembly by the consumer. Attached Figure Description

[0046] 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.

[0047] 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.

[0048] 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 separate structures (detachable and assembleable). For example, 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 an integral structure; for example, regardless of whether food needs to be poured out, the blending cup assembly 10 and the base 20 are assembled as one unit. Whether the blending cup assembly 10 and the base 20 are an integral structure or separate structures, the food processor includes a blending cup 1, a heating plate assembly 2, a motor 3, and a blade assembly 4.

[0049] See Figure 2 , Figure 3 , Figure 5 and Figure 6 The heating plate assembly 2 includes a heating plate 21 and a heating element 22. Combined with... Figure 1 and Figure 4 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; one embodiment is as follows: The heating plate assembly 2 includes a heating plate 21, a heating element 22, 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 be provided on the stirring cup 1. Regardless of the method, as long as the heating plate seal can achieve the aforementioned sealing function, it is acceptable. The heating element 22 includes a bottom opposite to the heating plate, and the projection of the bottom of the heating element on the heating plate 21 forms an annular area. That is, the heating element 22 is annular such that the projection of the bottom of the heating plate on the heating plate 21 forms the annular area. The annular shape of the heating element 22 can be a C-shaped annular shape formed by an arc or a curved annular shape; in short, the annular shape formed by the heating element 22 can heat the food. The ring shape can be a closed ring or an open ring.

[0050] See Figure 3 as well as Figures 5 to 8 The motor 3 includes a motor housing 31, a front motor bracket 32, and a motor shaft 33. The front motor bracket 32 ​​is not limited to the type shown. Figure 7 and Figure 8 The cover-like structure shown can be, for example, a tripod, a quadruped, or a frame structure. Some embodiments of the connection between the motor housing 31 and the motor front bracket 32 ​​are as follows: 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 ​​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. When the motor front bracket 32 ​​includes a bottom connecting portion 323, the top and bottom ends of the connecting frame 322 are connected to the top connecting portion 321 and the bottom connecting portion 323, respectively. The motor shaft 33 is rotatably connected to the top connecting portion 321, extends out of the top connecting portion 321, and connects to the blade assembly 4 along with the heating plate 21. For example, see... Figure 8The top connecting portion 321 includes a bearing mounting cavity, in which a bearing 3211 is mounted. The motor shaft 33 passes through the bearing 3211 to achieve the rotatable connection. The motor housing 31 includes a front end 311 connected to the front motor bracket 32. In this embodiment, the front end 311 is connected to the bottom connecting portion 323 to achieve the connection between the motor housing 31 and the front motor bracket 32. In other embodiments, the motor housing 31 and the front motor bracket 32 ​​are integrally formed to achieve the connection. The front motor 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 through-hole shape. In this case, the front end 311 of the outer casing is the section connected to the bottom connecting part 323. Alternatively, the motor outer casing 31 can also be roughly U-shaped, in which case the front end 311 is the narrow part of the U-shape. In short, the length of the front end 311 of the outer casing 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 of the outer casing and the bottom connecting part 323 can be achieved by clamping as described later, or by connecting with screws or other connecting parts. Those skilled in the art will understand that the connection between the motor front bracket 32 ​​and the front end 311 of the outer casing, as well as the rotatable connection with the motor shaft 33, is not limited to the above embodiments.

[0051] The motor 3 is a DC motor (brushed DC motor or brushless DC motor), see [link / reference] Figure 8 The height of the motor 3 along the axial direction of the motor shaft 33 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.

[0052] See Figure 3 , Figure 5 and Figure 6 The projections of the front end 311 of the outer casing and the front motor bracket 32 ​​as a whole onto the heating plate 21 are located within the annular area enclosed by the projections of the bottom of the heating element onto the heating plate. However, those skilled in the art will understand that, of the front end 311 of the outer casing and the front motor bracket 32, only the projection of the front motor bracket 32 ​​onto the heating plate 21 may be located within the annular area enclosed by the projections of the bottom of the heating element onto the heating plate 21. In this case, along the direction perpendicular to the motor shaft 33, the distance between the outer surface of the motor casing 31 and the heating element 22 is H (e.g., ...). Figure 2 , Figure 3 and Figure 6As shown), H≥0. In some embodiments, the radius of the motor 3 is R, 0≤H≤R / 2. The front bracket 32 ​​of the motor extends into the space 220 enclosed by the heating element 22 and the heating plate 21. In some embodiments, both the front end 311 of the outer casing and the front bracket 32 ​​of the motor may extend into the space 220.

[0053] As described above, since the projection of the motor front bracket 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 motor 3 can avoid the heating element 22 and approach the heating plate 21. Furthermore, the motor front bracket 32 ​​extends into the space 220 enclosed by the heating element 22 and the heating plate 21, which helps to reduce the distance between the motor 3 and the heating plate 21. Moreover, the motor is a DC motor, and its axial height along the motor shaft is L, 30mm≤L≤75mm, resulting in a relatively low axial height for the motor 3 itself (for example, under normal circumstances, the axial height of a DC motor is lower than that of a series-wound motor under equivalent performance). Therefore, the combination of these features helps to reduce the axial height of the food processor along the motor shaft 33. In the embodiments of this application, the aforementioned positional relationship reduces the height of the cup holder 6, thereby reducing the height of the mixing cup assembly 10, and ultimately reducing the axial height of the food processor along the motor shaft 33, making it more convenient for consumers to use the food processor. Furthermore, with the projection of the front end 311 of the outer casing also located within the annular region, and with the front end 311 of the outer casing also extending into the space 220, this design is advantageous for the low axial height of the motor, and the low axial height of the food processor along the motor shaft.

[0054] As for which component of the food processor motor 3 is assembled into, it is not limited, as long as the aforementioned positional relationship is satisfied. For example, see [link to relevant documentation]. Figures 5 to 7 The food processor includes a cup holder assembly. A motor 3 is assembled with the cup holder assembly. In one embodiment, the cup holder assembly includes a heating plate support 5, a cup holder 6, and a shock absorber 7. The heating plate support 5 is assembled with the mixing cup 1, and after assembly, the heating plate assembly 2 is clamped by the heating plate support 5 and the cup holder 6. In this application, both the heating plate 21 and the heating plate seal 23 include clamping portions 24, which clamp between the mixing cup 1 and the heating plate support 5. The motor 3 includes a rear motor support 34, and the food processor includes connecting arms 35 distributed circumferentially on the motor 3. The connecting arms 35 can be connected to the motor housing 31, or to the rear motor support 34, or, as... Figure 7 and Figure 8As shown, the connecting arm 35 is connected to both the motor housing 31 and the motor rear bracket 34. This connection can be either integrally formed with the motor 3 or assembled as a separate component. The number of connecting arms 35 is not limited to four; it can be five, three, or other combinations. The heating plate bracket 5 includes a first mounting portion 52. 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 second mounting portion 352 is located between the first mounting portion 52 and the third mounting portion 62. 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. After the bolt passes through the first mounting portion 52, the second mounting portion 352, and the third mounting portion 62, it is locked with the locking mechanism, thereby completing the assembly of the connecting arm 35, the cup holder 6, and the heating plate bracket 5, thus assembling the motor 3. In some other embodiments, the motor 3 can be assembled with the heating plate bracket 5 via the connecting arm 35, so that the motor 3 can be assembled with the cup holder assembly without being assembled with the heating plate assembly 2; in still other embodiments, the cup holder assembly includes a cup holder 6, and the motor 3 is assembled with the cup holder 6 via the motor housing 31, so that the motor 3 can be assembled with the cup holder assembly without being assembled with the heating plate assembly 2.

[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.

[0056] As described above, the motor 3 is assembled with the cup holder assembly. Combined with the aforementioned "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 21, and the motor front bracket 32 ​​extends into the space 220 enclosed by the heating element 22 and the heating plate 21", the motor 3 and the heating plate assembly 2 are not assembled together. Compared with the motor 3 being assembled on the cover plate of the heating plate bracket, the above arrangement at least reduces the thickness of the cover plate and the thickness of the related connecting parts. Furthermore, compared with the heating plate or heating element protruding from the mounting post and the motor being installed on the mounting post, this application does not require the installation post. Therefore, the distance between the motor 3 and the heating plate 21 along the axial direction of the motor shaft 33 is relatively short, which is beneficial to reducing the height of the food processor along the axial direction of the motor shaft 33. 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 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 corresponding screws. Secondly, since the motor 3 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 (such as the heating plate seal 23 becoming loose and causing poor sealing), and avoiding water leakage from the food processing chamber.

[0057] See Figure 3 , Figure 5 , Figure 6 and Figure 8 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 9 Along the direction indicated by arrows F1 or F2, the distance d2 is greater than d1. Furthermore, besides the stepped changes and gradual increases described later, the increase can also be that the distance on one side increases much more than the distance on the other side; for example, the connecting frame may be trapezoidal.

[0058] 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; one of the second connecting portions is connected to the motor housing 31, for example, the second connecting portion is 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. The other second connecting portion is connected to the top connecting portion of the motor front bracket.

[0059] 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 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 21, thus, with the top connecting part 321 as the starting point, compared to the distance between the first connecting part and the heating plate 21 being equal everywhere, the motor 3 is 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. In other words, considering the aforementioned conditions of "30mm≤L≤75mm, the projection of the motor front bracket on the heating plate being 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 extending into the space enclosed by the heating element and the heating plate," this application, while facilitating the reduction of the axial distance between the motor 3 and the heating plate 21 along the motor shaft 33, also helps to prevent the motor 3 from overheating during operation.

[0060] See Figure 3 , Figure 5 , Figure 6 and Figure 9 The maximum distance between the connecting bracket 322 and the heating plate 21 along the axial direction of the motor shaft 33 is d, which is 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.

[0061] As described above, since 5mm≤d≤25mm, the space enclosed by the motor front bracket 32, the heating plate 21, and the heating element 22 is relatively large (for example, after assembling the motor 3 with the cup holder assembly, the space enclosed by the motor front bracket 32, the heating plate 21, and the heating element 22 has no mounting structure, resulting in a larger space). This provides a larger heat dissipation space, which is more conducive to preventing excessive heat transfer from the heating plate assembly 2 to the motor 3, and helps to prevent the motor 3 from overheating during operation. In addition, with 5mm≤d≤25mm, it is also beneficial to reduce the axial height of the food processor along the motor shaft 33.

[0062] See Figure 3 , Figure 5 , Figure 6 and Figure 8 The distance between the connecting frame 322 and the heating plate 21 along the axial direction of the motor shaft 33 gradually increases in the radial direction of the motor shaft 33 towards the heating element 22, so that the distance between the connecting frame 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 towards the heating element 22. In this embodiment, see... Figure 7 and Figure 8 The connecting frame 322 includes a support sidewall that is shaped like a frustum. In other embodiments, the connecting frame 322 may also be shaped like a regular truncated pyramid by the support sidewall.

[0063] 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.

[0064] As described above, since the distance between the connecting bracket 322 and the heating plate 21 gradually increases along the axial direction of the motor shaft 33, the connecting bracket 322 can accommodate motor components (such as enameled wire). This means the internal components do not need to be lowered, and it also provides greater electrical clearance. Therefore, the motor itself is low in height, which helps to reduce the axial height of the mixing cup assembly along the motor shaft, making it more convenient for consumers to use the food processor. Of course, this design also helps to prevent excessive heat from the heating plate assembly 2 from being transferred to the motor 3.

[0065] See Figure 8The 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.

[0066] 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.

[0067] 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.

[0068] 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.

[0069] See Figure 9 The distance between the connecting frame 322 and the heating plate 21 along the axial direction of the motor shaft 33 varies in a stepped manner in the radial direction of the motor shaft 33 towards the heating element 22. This results in the distance between the connecting frame 322 and the heating plate 21 along the axial direction of the motor shaft 33 increasing in the radial direction of the motor shaft 33 towards the heating element 22, but this increase is a stepped increase. For example... Figure 9 In the given condition, d2 ≥ d1.

[0070] As described above, since the distance between the connecting frame 322 and the heating plate 21 along the axial direction of the motor shaft 33 changes in a stepped manner in the radial direction of the motor shaft 33 toward the heating element 22, compared with the first connecting part being parallel to the heating plate 21, the distance between the connecting frame 322 and the heating plate 21 is at least partially larger than the distance between the first connecting part and the heating plate 21. This is more conducive to the motor 3 being 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.

[0071] See Figure 9 The connecting frame 322 includes multiple steps. Figure 9 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 along the axial direction of the motor shaft 33 have a wider width in the direction perpendicular to the motor shaft 33. Figure 9 In the middle, the first step 3212 is farther away from the heating plate 21 than the second step 3213, and the first step 3212 is wider than the second step 3213.

[0072] As described above, the step further away from the heating plate 21 in the axial direction of the motor shaft 33 has a wider width in the direction perpendicular to the motor shaft 33, and the connecting bracket 322 is further away from the heating plate 21. This 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 overheating during operation.

[0073] See Figure 3 , Figure 5 and Figure 6 The food processor includes a heating plate support 5. The heating plate support 5 is assembled with the mixing cup 1 to clamp the heating plate assembly 2 between the heating plate support 5 and the mixing cup 1. The assembly method of the heating plate support 5 and the mixing cup 1 is not limited; for example, the heating plate support 5 and the mixing cup 1 can be assembled using a snap-fit ​​structure or a threaded structure. The heating plate support 5 includes a heat insulation portion 51. The formation of the heat insulation portion 51 is not limited; for example, the heating plate support 5 may extend axially along the motor shaft 33 and include a support opening 50. In this case, the front motor bracket 32 ​​extends through the support opening 50 into the space 220 enclosed by the heating plate 21 and the heating element 22. The heat insulation portion 51 includes the support opening 50. The heat insulation portion 51 is located between the heating element 22 and the front motor bracket 32, or the heat insulation portion 51 is located between the heating element 22 and the front motor bracket 32, and also between the heating plate 21 and the front motor bracket 32.

[0074] As described above, by setting the heat insulation part 51, which is located between the heating element 22 and the front bracket of the motor 32, or between the heating element 22 and the front bracket of the motor 32 and between the heating plate 21 and the front bracket of the motor 32, 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 overheating during operation.

[0075] See Figure 3 The motor 3 includes a rear motor bracket 34. The front motor bracket 32 ​​and the rear motor bracket 34 are fastened together, and the motor housing 31 is clamped between the front motor bracket 32 ​​and the rear motor bracket 34. The method of fastening the front motor bracket 32 ​​and the rear motor bracket 34 is not limited; see [reference needed]. Figure 3 and Figure 8 The front motor bracket 32 ​​and the rear motor bracket 34 are respectively provided with mounting holes 320. Bolts pass through the mounting holes 320 and are fastened to the front motor bracket 32 ​​and the rear motor bracket 34 with locking parts (such as nuts or screws). After fastening, the motor housing 31 is clamped between the front motor bracket 32 ​​and the rear motor bracket 34.

[0076] As described above, since the front motor bracket 32 ​​and the rear motor bracket 34 are fastened together to clamp the motor housing 31 between the front motor bracket 32 ​​and the rear motor bracket 34, the assembly of the motor 3 is simple and convenient.

[0077] See Figure 7 The motor housing 31 is through-hole shaped and includes two opposing openings (a front opening and a rear opening). 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.

[0078] 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.

[0079] 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.

[0080] 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.

[0081] In some embodiments, the motor 3 satisfies at least one of the following conditions: the diameter of the motor 3 is w, w≤76.5mm; the motor load torque is T, 105N·m≤T≤135N·m; the motor no-load speed is V, 12000r / min≤V≤14500r / min; the motor load speed is v: 9000r / min≤v≤11000r / min; the stirring cup assembly includes a cup holder assembly, the cup holder assembly includes the motor, and the height of the cup holder assembly along the axial direction of the motor shaft is k, k≤85mm (see...). Figure 5 ).

[0082] As described above, the food processor meets at least one of the above conditions, which helps ensure that the height of the motor or cup holder assembly is low. Consequently, the height of the mixing cup assembly 10 along the axial direction of the motor shaft 33 is low, which also ensures 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.

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.
