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 relationship between the motor front bracket and the heating element restricts the placement of related components (such as enameled wire), resulting in a relatively high axial height of the aforementioned food processor along the motor shaft. Utility Model Content

[0004] The purpose of this application is to disclose a food processor. The food processor has a relatively low height along the axial direction of 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 motor includes a motor housing, a front motor bracket, and a motor shaft; the front motor 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 is also used to drive the blade assembly to rotate. The motor is a DC motor, and the axial height of the motor shaft is L, 30mm≤L≤75mm. The heating plate assembly includes a heating plate and a heating element; the front motor bracket extends into the space enclosed by the heating element on the heating plate, and the projection of the front end of the front motor bracket or the motor housing on the heating plate is located outside the annular area enclosed by the heating element on the heating plate; 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 towards the heating element.

[0006] As described above, since the front bracket of the motor extends into the space enclosed by the heating plate and the heating element, the projection of the front end of the front bracket of the motor or the outer shell of the motor housing on the heating plate is located outside the annular area enclosed by the heating element on the heating plate. In this way, the distance between the motor and the heating plate along the axial direction of the motor shaft is relatively short, which helps to reduce the height of the food processor along the axial direction of the motor shaft.

[0007] Furthermore, since 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, this application ensures that the front bracket of the motor is far from the heating plate while reducing the distance between the motor and the heating plate. This helps to avoid excessive heat transfer from the heating plate and the heating element to the motor and helps to avoid excessive temperature during motor operation.

[0008] Finally, the gradual increase in size allows for the assembly of motor components (such as enameled wire) inside the connecting frame, and also provides greater electrical clearance. Therefore, the low axial height of the motor itself along the motor shaft also contributes to the low axial height of the food processor along the motor shaft.

[0009] In some embodiments, the connecting frame includes a support sidewall that is shaped like a frustum or a truncated pyramid.

[0010] 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.

[0011] 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.

[0012] In some embodiments, the food processor includes a blending cup assembled with the heating plate assembly. The heating plate includes a plate body and a protrusion projecting inward toward the interior of the blending cup, the plate body circumferentially surrounding the protrusion; the connecting bracket intersects with the top connecting portion at a point 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.

[0013] 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 plate; the top connecting portion extends into the protrusion, which is more conducive to reducing the axial height of the food processor along the motor shaft. Furthermore, the extension of the top connecting portion into the protrusion can also help position the motor during assembly, making motor assembly convenient.

[0014] In some embodiments, the minimum distance that the front bracket of the motor avoids the heating element is Y, where Y ≥ 2 mm.

[0015] As described above, by setting the distance Y, excessive heat from the heating element is prevented from being transferred to the motor, thus preventing the motor from overheating during operation.

[0016] 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.

[0017] 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.

[0018] In some embodiments, the food processor includes a blending cup and a cup holder assembly, the cup holder assembly being connected to the blending cup assembly. The cup holder assembly includes a heating plate support, the edge of which is clamped between the heating plate support and the blending cup. The cup holder assembly includes a cup holder, and the motor is assembled with at least one of the cup holder and the heating plate support.

[0019] As described above, when the cup holder assembly includes a heating plate bracket, the motor front bracket extends into the space enclosed by the heating plate and the heating element. Compared to the aforementioned embodiment with a cover plate, this configuration at least reduces the thickness of the cover plate and the thickness of related connecting parts. Furthermore, compared to the embodiment where the heating plate or heating element protrudes from the mounting post and the motor is mounted to 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. In addition, assembling the motor with at least one of the cup holder or the heating plate bracket has several advantages. First, compared to assembling the motor with the mounting post of the heating plate or heating element, not assembling the motor with the mounting post of the heating plate assembly helps to prevent heat from the heating plate assembly from being transferred to the motor through the mounting post and corresponding screws. Second, not assembling the motor with the heating plate assembly prevents the motor's vibration from causing vibration of the heating plate, thus preventing poor sealing between the heating plate assembly and the mixing cup (e.g., loose heating plate seals leading to poor sealing), and avoiding water leakage from the food processing chamber.

[0020] In some embodiments, the heating plate support includes a first mounting portion. The motor includes a rear motor support, and the food processor includes connecting arms distributed circumferentially around the motor; the connecting arms are connected to the motor housing and / or the rear motor support, and include a second mounting portion. The cup holder includes a third mounting portion. The third mounting portion, the second mounting portion, and the first mounting portion are assembled together.

[0021] 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.

[0022] 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.

[0023] As described above, since the shock absorber is located between the first mounting part and the second mounting part, and also 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.

[0024] 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; and the top surface of the motor housing is not lower than the abutment surface.

[0025] 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.

[0026] 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.

[0027] 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, helping to prevent overheating during operation. Simultaneously, carbon dust generated by the motor can also be discharged to the outside through the through hole. Furthermore, the front and rear motor brackets are cap-shaped; this design provides both high strength and prevents liquids such as water from entering the motor.

[0028] 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.

[0029] As described above, the arrangement between the motor and heating plate assembly in any of the aforementioned food processors helps to reduce the axial height of the mixing cup assembly along the motor shaft. Consequently, the mixing cup assembly and the base can be detachably assembled, making it easier for consumers to pick up and put down the mixing cup assembly when it is necessary to pour out the food in the mixing cup.

[0030] 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 blending cup assembly includes a cup holder assembly assembled with the blending cup, 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.

[0031] As described above, the food processor meets at least one of the above conditions, which helps ensure a low height for the motor or cup base assembly, and consequently, a low height for the mixing cup assembly along the motor shaft. This also ensures a low height for the mixing cup assembly. Furthermore, when the mixing cup assembly and base are detachable, it facilitates convenient placement and removal of the mixing cup assembly by the consumer. Attached Figure Description

[0040] 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.

[0041] 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.

[0042] See Figure 1 and Figure 2 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.

[0043] See Figure 3 and Figure 7 The motor 3 includes a motor housing 31, a motor front bracket 32, and a motor shaft 33. The motor 3 is a DC motor, and the axial height along the motor shaft 33 is L, 30mm ≤ L ≤ 75mm (see [reference]). Figure 7For example, 30mm, 32mm, 35mm, 38mm, 40mm, 43mm, 45mm, 48mm, 50mm, 53mm, 55mm, 57mm, 60mm, 62mm, 65mm, 68mm, 70mm, 72mm, or 75mm. The motor front bracket 32 ​​is not limited to such... Figure 5 and Figure 7 The cover-like structure shown can be, for example, a tripod, a quadruped, or a frame structure. 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 front end 311 of the motor housing 31 is connected to the bottom connecting portion 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 for connection. Furthermore, the motor front bracket 32 ​​is not limited to being connected to the motor housing 31. The motor housing 31 is in 5 and Figure 7 The outer casing is cylindrical with a continuous shaft. 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 parts such as screws. The motor shaft 33 is rotatably connected to the top connecting part 321 and is also used to drive the blade assembly 4 to rotate. For example, see Figure 7 The 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. Those skilled in the art will understand that the connection between the motor front bracket 32 ​​and the front end 311 of the housing, and the rotatable connection with the motor shaft 33, is not limited to the above-described embodiments.

[0044] The heating plate assembly 2 includes a heating plate 21 and a heating element 22. The heating element 22 heats the food within the food processing cavity formed by the heating plate assembly 2 and the stirring cup 1 via the heating plate 21. See also Figure 2The heating plate assembly 2 and the stirring cup 1 form a food processing cavity. The arrangement of the food processing cavity is not limited; one embodiment is as follows: the heating plate assembly 2 further includes 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 with the heating plate assembly and the stirring cup 1. In other embodiments, the heating plate seal may be provided on the stirring cup 1; regardless of the arrangement, as long as the heating plate seal can achieve the aforementioned sealing function, it is acceptable.

[0045] See Figure 3 The motor front bracket 32 ​​extends into the space 220 formed by the heating plate 21 and the heating element 22. The projection of the motor front bracket 32 ​​on the heating plate 21 is located outside the annular area formed by the heating element 22 on the heating plate 21. Alternatively, the projection of the front end 311 of the motor housing 31 on the heating plate 21 is located outside the annular area formed by the heating element 22 on the heating plate 21. Through the motor front bracket 32, or the projection of the front end 311 of the motor housing 31 on the heating plate 21 being located outside the annular area formed by the heating element 22 on the heating plate 21, the distance between the outer surface of the motor front bracket 32 ​​and the inner side of the heating element 22 along a direction perpendicular to the motor shaft 33 is H (e.g., ...). Figure 3 As shown), H≥0. Figure 3 In this context, the minimum distance Y that the motor front bracket 32 ​​must avoid from the heating element 22 is ≥ 2mm. The minimum distance refers to the width of the gap formed between the heating element 22 and the motor front bracket 32. Figure 3 In this context, the interval is larger closer to the heating plate 21, and the width is the distance between the inner end of the heating element 22 away from the heating plate 21 and the front bracket 32 ​​of the motor. By setting this distance Y, excessive heat from the heating element 22 is prevented from being transferred to the motor, thus avoiding excessive temperature during motor operation. The annular area formed by the heating element 22 on the heating plate 21 mainly refers to the annular area formed by the root of the heating plate (or the intersection line between the heated element 22 and the heating plate 21) on the heating plate 21. Figure 3 In this design, the heating element 22 forms a ring-shaped area on the heating plate 21. This ring shape can be a C-shape formed by an arc or a curved line; the key is that the ring formed by the heating element 22 can heat the food. The ring can be closed or open. (See also...) Figure 3 The distance between the connecting bracket 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 toward the heating element 22. (See also...) Figure 3The distance gradually increases along the directions indicated by arrows F1 and F2, meaning that distance d2 is greater than d1. There are various structures that can achieve this gradual increase; for example, in some embodiments, the connecting frame 322 includes a support sidewall that forms a frustum or a truncated pyramid shape.

[0046] As described above, since the front bracket 32 ​​of the motor extends into the space 220 formed by the heating element 22 on the heating plate 21, the projection of the front bracket 32 ​​of the motor or the front end 311 of the outer casing on the heating plate 21 is located outside the annular area formed by the heating element 22 on the heating plate 21. In this way, 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.

[0047] Furthermore, 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 a second connecting portion; 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 formed by the heating element 22 on the heating plate 21, and the motor 3 also satisfies the aforementioned relationship. With the top connecting part 321 as a reference, in this application, since 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 toward the heating element 22, compared with the distance between the first connecting part and the heating plate 21 being equal everywhere, this application ensures that the front bracket 32 ​​of the motor 3 is farther away from the heating plate 21 while reducing the distance between the motor 3 and the heating plate 21. This is beneficial to avoid excessive heat transfer from the heating plate 21 and the heating element 22 to the motor 3, and to avoid the motor 3 from overheating during operation.

[0048] Finally, in some embodiments, 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, i.e., the first and second sections form an L-shape. Due to safety regulations, internal motor components need to be moved downwards (e.g., the enameled wire needs to be a certain distance from the second section), resulting in a larger motor height and consequently, a larger height of the food processor along the motor shaft. This gradual increase allows for the assembly of motor components (e.g., the enameled wire) inside the connecting frame 332, meaning the internal components (e.g., the enameled wire) do not need to be moved downwards, and greater electrical clearance can be provided. Therefore, a lower height of the motor 3 itself along the motor shaft also contributes to a lower height of the food processor along the motor shaft 33.

[0049] In some embodiments of this application, the mixing cup assembly 10 and the base 20 are separate structures. The mixing cup assembly 10 includes a cup holder assembly. The above-mentioned arrangement can reduce the height of the cup holder assembly along the axial direction of the motor shaft 33, thereby reducing the height of the mixing cup assembly 10 along the axial direction of the motor shaft 33, and further reducing the height of the food processor along the axial direction of the motor shaft 33.

[0050] See Figure 7 The angle between the side wall of the bracket and the plane perpendicular to the motor shaft 33 is α, where 110 degrees ≤ α ≤ 150 degrees. For example, 110 degrees, 112 degrees, 115 degrees, 118 degrees, 120 degrees, 123 degrees, 125 degrees, 128 degrees, 130 degrees, 133 degrees, 135 degrees, 138 degrees, 140 degrees, 143 degrees, 145 degrees, 148 degrees, 149 degrees, or 150 degrees.

[0051] 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.

[0052] See Figure 3 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 3 The height difference is shown as p. The top connecting part 321 extends into the protrusion 212. 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 3 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.

[0053] As described above, since the protrusion 212 protrudes towards the interior of the mixing 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 plate; the top connecting portion 321 extends into the protrusion 212, which is more conducive to reducing the height of the food processor along the axial direction of the motor shaft 33. In addition, the extension of the top connecting portion 321 into the protrusion 212 can also help position the assembly of the motor 3, making the assembly of the motor convenient.

[0054] See Figure 3 In some embodiments, the distance between the connecting frame 322 and the heating plate 21 along the axial direction of the motor shaft 33 is increased to d, that is, d1 increases to d2, d2 increases to d, meaning that the maximum distance between the connecting frame 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.

[0055] 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.

[0056] In embodiments of this application, the motor 3 is not limited to any particular component of the food processor, as long as the aforementioned positional relationship is satisfied. For some embodiments, see [link to relevant documentation]. Figure 3The food processor includes a blending cup 1 and a cup holder assembly. The cup holder assembly includes a heating plate support 5 and a cup holder 6. The heating plate support 5 includes a support opening 50, through which the motor front support 32 extends into the space 220 formed by the heating plate 21 and the heating element 22. In some embodiments, the heating plate support 5 is assembled with the blending cup 1, and the cup holder 6 is assembled with the heating plate support 5. More specifically, the assembly method of the cup holder 6 with the heating plate support 5 is not limited. The heating plate support and the blending cup 1 are assembled as follows: the heating plate support 5 and the blending cup 1 are assembled by a snap-fit ​​structure or a threaded structure. After the heating plate support 5 and the blending cup 1 are assembled, the edge of the heating plate assembly 2 is clamped between the heating plate support 5 and the blending cup 1, so that the heating plate 21 and the blending cup 1 form a food processing cavity. At the same time, under the aforementioned clamping action, the heating plate seal 23 seals the food processing cavity, thereby forming a food processing cavity between the heating plate assembly 2 and the blending cup 1. In some other embodiments, the cup holder assembly includes a cup holder 6. The heating plate assembly 2 is clamped between the cup holder 6 and the stirring cup 1, rather than between the heating plate support 5 and the stirring cup 1. In this case, the heating plate support 5 and the cup holder 6 are assembled to achieve the clamping. Regardless of how the heating plate assembly 2 is clamped between the heating plate support 5 and the stirring cup 1, the motor is assembled with at least one of the cup holder 6 and the heating plate support 5.

[0057] 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. This embodiment also results in a relatively high height of the food processor along the motor shaft.

[0058] As described above, when the cup holder assembly includes the heating plate bracket 5, the motor front bracket 32 ​​extends into the space 220 enclosed by the heating plate 21 and the heating element 22. Compared with the aforementioned embodiment with a cover plate, 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 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 closer, which is beneficial to reducing the height of the food processor along the axial direction of the motor shaft. Furthermore, the motor 3 is assembled with at least one of the cup holder 6 and the heating plate bracket 5. On the one hand, compared with the motor 3 being installed with the mounting post of the heating plate 21 or the heating element 22, the fact that the motor 3 is not assembled with the mounting post of the heating plate assembly 2 helps to prevent the heat of the heating plate assembly from being transferred to the motor through the mounting post and the corresponding screws. On the other hand, 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, and thus will not lead to poor sealing between the heating plate assembly 2 and the mixing cup 1 (such as the heating plate seal 23 becoming loose), thus avoiding water leakage from the food processing chamber.

[0059] The following describes an embodiment in which the motor 3 is assembled with the cup holder 6 and the heating plate bracket 5: The heating plate bracket 5 includes a first mounting part 52. (See also...) Figure 4 , Figure 5 , Figure 6 and Figure 8 The motor 3 includes a rear motor bracket 34. One embodiment of assembling the rear motor bracket 34, the front motor bracket 32, and the motor housing 31 is as follows: 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, in conjunction with locking components (such as nuts or screws), fasten the front motor bracket 32 ​​and the rear motor bracket 34. After fastening, 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 fastened together to clamp the motor housing 31, the assembly of the motor 3 is simple and convenient.

[0060] The food processor includes connecting arms 35 circumferentially distributed around the motor 3. The connecting arms 35 can be connected to the motor housing 31, or to the motor rear support 34, or, as... Figure 7 and Figure 8As shown, it is connected to both the motor housing 31 and the motor rear bracket 34. The connection can be an integral part of the connecting arm 35 and the motor 3, or it can be assembled as a separate component of the motor 3. The number of connecting arms 35 is not limited to four; it can be five, three, etc. The connecting arm 35 includes a second mounting portion 352. The cup holder 6 includes a third mounting portion 62. The third mounting portion 62, the second mounting portion 352, and the first mounting portion 52 are assembled together, and their assembly is not limited to the bolt and locking mechanism described later.

[0061] 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.

[0062] In some embodiments, the food processor further 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. 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 a locking member, thereby completing the assembly between the connecting arm 35, the cup holder 6, and the heating plate support 5, thereby assembling the motor 3.

[0063] As described above, since the shock absorber 7 is located between the first mounting part 52 and the second mounting part 352, and between the second mounting part 352 and the third mounting part 62, the shock absorber 7 is beneficial to reduce the vibration caused by the operation of the motor 3, for example, it is beneficial to reduce the noise caused by the vibration.

[0064] See Figure 4 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.

[0065] As described above, since one of the first mounting part 52 and the third mounting part 62 includes a positioning groove; the other of the first mounting part 52 and the third mounting part 62 passes through the second mounting part 352 and is located in the positioning groove, the assembly of the heating plate bracket 5, the cup holder 6 and the connecting arm 35 is simple and precise through this positioning.

[0066] See Figure 3 , Figures 5 to 8 The motor housing 31 forms a bottom opening. The motor rear bracket 34 covers the bottom opening. 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 motor rear bracket 34. The second connecting arm 354 contacts the motor housing 31 and extends axially along the motor shaft 33. The contact can be between the second connecting arm 354 and the outer surface of the motor housing 31, or it can be embedded within the motor housing 31. The second connecting arm 354 is connected to the second mounting portion 352. In some embodiments, both the motor rear bracket and the connecting arms are made of plastic.

[0067] 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.

[0068] See Figure 6 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 6 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.

[0069] 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.

[0070] See Figure 6 and Figure 8 The motor rear bracket 34 includes a flat bracket body 341 and a converging portion 342 protruding from the bracket body 341. The converging portion 342 can also be flat (as shown in the figure, a circular plate; the flatness can be understood as the bracket body 341 or the converging portion comprising relatively parallel planes, such as a cylinder, etc.). Of course, the converging portion 342 can be small and not flat, as long as it does not significantly affect the height. The bracket body 341 can be circular or not; its shape is determined by the shape of the bottom opening of the motor housing 31. The bracket body 341 covers the bottom opening. All connecting arms 35 converge at the converging portion 342.

[0071] As described above, since the motor rear bracket 34 includes a flat bracket body 341 and a gathering part 342, and the height of the motor rear bracket 34 is the sum of the thickness of the bracket body 341 and the height of the gathering part 342, the height is relatively low. Therefore, the assembly of this structure of the motor rear bracket 34 with the motor housing 31 also helps to reduce the height of the food processor along the axial direction of the motor shaft 33.

[0072] See Figure 7 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.

[0073] 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.

[0074] See Figure 3 and Figure 4 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 3 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.

[0075] 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.

[0076] 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 5 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.

[0077] 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.

[0078] 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.

[0079] 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.

[0080] 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 assembled with the stirring cup 1, the cup holder assembly includes the motor 3, and the height of the cup holder assembly along the axial direction of the motor shaft 33 is k, k≤85mm (see...). Figure 2 and Figure 3 ).

[0081] As described above, the food processor meets at least one of the above conditions, which helps to ensure that the height of the motor 3 or the cup base 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 the consumer in conveniently taking the mixing cup assembly out and putting it in.

[0082] 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.
