[0002] The cup body assembly of an existing food processing machine generally includes an axially through-going cup body and a heating plate provided at the bottom opening of the cup body. The heating plate heats the material in the cup body to process the food. The heating plate is usually installed from the bottom of the cup body. For example, patent CN209712658U discloses a food processing machine, in which an electric heater is embedded in the cup body from the bottom, and the electric heater is clamped between the cup body and the cup base. During installation, the electric heater needs to be inserted from the bottom of the cup body, and then the user needs to hold the electric heater by hand to ensure that it does not fall off before installing the cup base. The installation difficulty is relatively high, which affects the installation efficiency.

[0003] Furthermore, the electric heating element of the above patent is convexly arranged relative to the cup body, occupying a portion of the space inside the cup body. When the processing capacity is constant, the size of the cup body needs to be increased, which is costly.

[0004] How to optimize the shape of the heating plate without increasing the cost and improve the installation of the heating plate are currently the issues that need attention. Utility Model Content

[0005] The utility model provides a food processor, aiming to solve the problems that the existing cup body assembly comprising a cup body and a cup base clamping a heating plate is difficult to install and the use of a convex heating plate leads to high material costs for the cup body.

[0006] The utility model discloses a food processor, comprising a cup body assembly with a built-in motor assembly, the cup body assembly comprising a stirring cup with an opening at the bottom, a heating plate arranged at the opening, and a cup body bracket; a stirring blade assembly driven by the motor assembly is provided in the stirring cup, and an inner wall of the stirring cup located above the opening is provided with a step portion; the heating plate is inserted into the stirring cup through the top opening of the stirring cup and overlaps the step portion; the bottom of the heating plate passes through the opening and is fixed to the cup body bracket, and the heating plate and the cup body bracket jointly clamp the stirring cup; the heating plate is sunken relative to the stirring cup and an auxiliary crushing chamber is formed on the inner side of the heating plate; the motor assembly is fixed below the heating plate and is integrated with the heating plate; the upper end of the motor shaft of the motor assembly passes through the heating plate, extends into the stirring cup, and is fixed to the stirring blade assembly.

[0007] The food processing machine of the present invention also has the following additional technical features:

[0008] The heating plate includes a bottom plate and a rim extending upwards from the edge of the bottom plate and surrounding the bottom plate, and the rim is arranged to fit the inner wall of the lower end of the stirring cup.

[0009] The top end of the surrounding edge is folded outward to form a flange portion, and the flange portion is overlapped on the step portion.

[0010] The cup body support is provided with a support portion extending radially inward, the bottom of the stirring cup is supported by the support portion, and the horizontal projection of the flange portion is located within the horizontal projection range of the support portion.

[0011] A sealing ring is provided between the heating plate and the step portion.

[0012] The inner wall of the stirring cup is provided with an axially extending spoiler rib, and the top end of the heating plate is not lower than the bottom end of the spoiler rib.

[0013] The heating plate includes a heating plate body and a heating tube provided on the bottom wall of the heating plate body. The heating tube and the heating plate body are integrally die-cast, or the heating tube is fixed to the heating plate body.

[0014] The motor assembly is flexibly suspended on the heating plate; or, the motor assembly includes a motor body and a motor lower cover, and the heating plate and the motor lower cover jointly surround the motor body.

[0015] The motor assembly includes a motor, which is a brushless motor.

[0016] The heating plate comprises a bottom plate and a boss protruding upward from the center of the bottom plate, and the stirring blade assembly is suspended above the boss.

[0017] Due to the adoption of the above technical solution, the utility model has the following beneficial effects:

[0018] 1. Compared with the prior art method of installing the heating plate from the bottom of the cup body, the heating plate of the present application is installed from the top of the cup body. The heating plate can be initially positioned by inserting the cup body from the top of the cup body and then moving it to overlap the step portion. The advantage of this is that after the heating plate is initially positioned, it can be ensured that the heating plate does not fall off without being supported by hand, which reduces the difficulty of installation and is conducive to improving installation efficiency.

[0019] In addition, the heating plate of the present application is sunken relative to the mixing cup, which is beneficial to reducing the size of the cup body under the condition of a certain processing capacity, thereby saving processing costs.

[0020] 2. In the prior art (patent CN209712658U), in which the upper convex heating plate is embedded in the cup body, the annular side wall of the heating plate only serves as an installation. The present application forms an auxiliary crushing chamber on the inner side of the heating plate, which can increase the contact area between the material and the heating plate. The material is easier to crush after being heated and softened in the auxiliary crushing chamber, which can improve the crushing effect; the heating plate includes a base plate and a surrounding edge that surrounds the base plate from the edge of the base plate upwards. The surrounding edge extends into the mixing cup, which can not only meet the installation requirements of the heating plate, but also heat the material moving along the surrounding edge, thereby enhancing the heating effect of the material.

[0021] Furthermore, the top end of the surrounding edge is folded outward to form a flange portion, and the flange portion is overlapped on the step portion; by providing the flange portion, the heating plate can be firmly overlapped on the step portion, and at the same time it helps to radially limit the heating plate, thereby ensuring the concentricity of the heating plate and the stirring cup, and improving the installation effect of the heating plate.

[0022] Furthermore, the cup body bracket is provided with a support portion extending radially inward, the bottom of the blending cup is supported on the support portion, and the horizontal projection of the flange portion is located within the horizontal projection range of the support portion; by arranging the flange portion and the support portion in correspondence with each other, the clamping effect of the two on the blending cup can be enhanced. If the two are misaligned, the support portion may not have enough force to press the blending cup upward against the heating plate, and the overall compactness and firmness cannot be guaranteed. Therefore, the flange portion is required to overlap with the support portion in the radial direction.

[0023] 3. In order to prevent liquid from flowing into the cup body shell below from the matching gap between the heating plate and the blending cup and damaging the internal electrical components, and to prevent materials or residues from being caught in the matching gap between the heating plate and the blending cup and causing odor, a sealing ring is provided between the heating plate and the step portion to provide a reliable seal.

[0024] 4. In order to improve the crushing effect of the material, the inner wall of the mixing cup is provided with axially extending spoiler ribs, and the top of the heating plate is not lower than the bottom of the spoiler ribs. By optimizing the arrangement of the spoiler ribs, it is beneficial for the material to be cut in the auxiliary crushing chamber and then act on the spoiler ribs as soon as possible, which can increase the frequency of contact between the material and the spoiler ribs, enhance the turbulent effect, and improve the crushing efficiency.

[0025] 5. The heating plate includes a heating plate body and a heating tube arranged on the bottom wall of the heating plate body. The matching mode of the heating tube and the heating plate body can be flexibly set according to actual needs. The two can be set as one or separately to increase the flexibility of accessory processing.

[0026] 6. The motor assembly of the present application may be composed of a complete structure, such as a motor assembly comprising a motor upper cover, a motor body, and a motor lower cover, with the motor assembly flexibly hoisted to the heating plate. The flexible hoisting can reduce the transmission of motor vibration to the heating plate, thereby reducing the possibility of the heating plate loosening. Alternatively, the motor assembly may comprise a motor body and a motor lower cover, with the heating plate and the motor lower cover jointly surrounding the motor body. The motor upper cover can be omitted, with the heating plate serving as the motor upper cover. This simplifies the configuration of the motor assembly and facilitates a more compact arrangement of the motor assembly and the heating plate.

[0027] 7. The motor of the present application may be a brushless motor. On the one hand, the brushless motor is small in size and light in weight, which can reduce the installation burden of the heating plate and is beneficial to the stable operation of the cup body assembly. On the other hand, the flattening of the brushless motor can reduce the overall axial size of the cup body assembly, which is beneficial to the miniaturization and lightness of the entire machine.

[0028] 8. Usually, the blade of the stirring blade assembly is located at a certain height above the bottom of the heating plate. In order to prevent the stirring blade assembly from shaking and causing unstable operation or even knife jamming when it is protruding too high, the heating plate includes a chassis and a boss protruding upward from the center of the chassis. The stirring blade assembly is suspended above the boss. By setting the boss, it can support and limit the motor shaft, thereby preventing the upper end of the motor shaft from shaking and affecting the stability of the stirring blade assembly.

[0040] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of such features.

[0043] like Figures 1 to 4 As shown, the present application provides a food processor, including a cup body assembly 10 with a motor assembly 15 therein, the cup body assembly 10 including a blending cup 11 with an opening at the bottom, a heating plate 12 arranged at the opening, and a cup body bracket 13, a blending blade assembly 16 driven by the motor assembly 15 is provided in the blending cup 11, an inner wall of the blending cup 11 above the opening is provided with a step portion 111, the heating plate 12 is inserted into the blending cup 11 from the top opening of the blending cup 11 and overlaps the step portion 111, the bottom of the heating plate 12 is fixed to the cup body bracket 13 through the opening, and the heating plate 12 and the cup body bracket 13 jointly clamp the blending cup 11, the heating plate 12 is sunken relative to the blending cup 11 and an auxiliary crushing chamber 121 is formed on the inner side of the heating plate 12, the motor assembly 15 is fixed below the heating plate 12 and is integrated with the heating plate 12, the upper end of the motor shaft 151 of the motor assembly 15 passes through the heating plate 12 and extends into the blending cup 11 and is fixed to the blending blade assembly 16.

[0044] Compared to the prior art method of installing the heating plate from the bottom of the cup body, the heating plate 12 of the present application is installed from the top of the cup body. By inserting the cup body from the top of the cup body and then moving it to overlap the step portion 111, the heating plate 12 can be initially positioned. The advantage of this is that after the heating plate 12 is initially positioned, it can be ensured that the heating plate 12 does not fall off without being supported by hand, which reduces the difficulty of installation and helps to improve installation efficiency. In addition, the heating plate 12 of the present application is set downward relative to the mixing cup 11. Under the condition of a certain processing capacity, it is beneficial to reduce the size of the cup body, thereby saving processing costs.

[0045] The traditional heating plate needs to be aligned with the cup body from the bottom of the cup body. Not only does it need to lift the cup body to ensure that the bottom of the cup body can be seen during installation, which makes the operation laborious, but it is also difficult to align the heating plate from the bottom of the cup body. In addition, after the heating plate is aligned, it needs to be supported to fix it. The whole process is complicated and inefficient. The heating plate 12 of the present application is inserted from the top of the mixing cup 11 without lifting the mixing cup 11, and the opening at the top of the mixing cup 11 is usually larger, which makes it easy to align and insert the heating plate 12, and it is less difficult. Figure 2 and Figure 3 As shown, the heating plate 12 of the present application is bowl-shaped, and the inner bottom wall of the heating plate 12 is flush with the bottom end of the mixing cup 11 or the inner bottom wall of the heating plate 12 is lower than the bottom end of the mixing cup 11. In either case, when the processing capacity is constant, there is no need to increase the axial dimension of the mixing cup 11. In particular, when the inner bottom wall of the heating plate 12 is lower than the bottom end of the mixing cup 11, a smaller mixing cup 11 can be used, which is beneficial to cost saving.

[0046] A cup housing 14 is provided on the outer side of the lower end of the blending cup 11, enclosing the cup support 13, blending cup 11, heating plate 12, and motor assembly 15, giving the cup assembly 10 a simple appearance. An upper coupler 141 is provided at the bottom of the cup housing 14, and a lower coupler is provided on the main unit 17 of the food processor. When the cup assembly 10 is placed on the main unit 17, the upper and lower couplers cooperate to power it. The blending blade assembly 16 may include one or more blades, which may be riveted to the motor shaft 151. Directly securing the blades to the motor shaft 151 eliminates the need for a blade shaft, facilitating more stable operation. An auxiliary crushing chamber 121 is formed within the heating plate 12, while a main crushing chamber is formed within the blending cup 11 above the heating plate 12. The material at the bottom of the blending cup 11 is heated and softened in the auxiliary crushing chamber 121. After the blades are activated, the material passes through the auxiliary crushing chamber 121 and reaches the main crushing chamber. Ultimately, under the influence of the spoiler ribs 114 and gravity, the material falls back to the vicinity of the blades for crushing.

[0047] like Figure 4As shown, the step portion 111 is formed integrally during the processing of the blending cup 11. The blending cup 11 includes a first section 112 with a first inner diameter and a second section 113 with a second inner diameter from top to bottom. The second inner diameter is smaller than the first inner diameter. The first section 112 and the second section 113 transition through the step portion 111 to form a variable diameter setting for the blending cup 11. The processing method of this step portion 111 is simple and low-cost, and the reduced diameter setting of the second section 113 relative to the first section 112 is conducive to radial cooperation with the heating plate 12.

[0048] In the prior art (patent CN209712658U) in which the upward convex heating plate is embedded in the cup body, the annular side wall of the heating plate only serves as an installation. The present application forms an auxiliary crushing chamber 121 on the inner side of the heating plate 12, which can increase the contact area between the material and the heating plate 12. The material is easier to crush after being heated and softened in the auxiliary crushing chamber 121, which can improve the crushing effect.

[0049] As a preferred embodiment, the heating plate 12 includes a bottom plate 122 and a rim 123 extending from the edge of the bottom plate 122 upwardly around the bottom plate 122, and the rim 123 is arranged in contact with the inner wall of the lower end of the mixing cup 11. Figure 3 As shown, the edge 123 extends into the mixing cup 11, which can not only meet the installation requirements of the heating plate 12, but also heat the materials moving along the edge 123, thereby enhancing the heating effect on the materials.

[0050] As a preferred embodiment of the present embodiment, the top end of the surrounding edge 123 is folded outward to form a flange portion 124, which overlaps the step portion 111. The flange portion 124 can ensure that the heating plate 12 is firmly overlapped on the step portion 111, and at the same time helps to radially limit the heating plate 12, thereby ensuring the concentricity of the heating plate 12 and the mixing cup 11, and improving the installation effect of the heating plate 12.

[0051] Furthermore, the cup body support 13 is provided with a support portion 131 extending radially inward, the bottom of the mixing cup 11 is supported on the support portion 131, and the horizontal projection of the flange portion 124 is located within the horizontal projection range of the support portion 131. Figure 3 and Figure 4 As shown, by arranging the flange portion 124 and the support portion 131 in correspondence, the clamping effect of the two on the mixing cup 11 can be enhanced. If the two are misaligned, the support portion 131 may not have enough force to press the mixing cup 11 upward against the heating plate 12, and the overall compactness and firmness cannot be guaranteed. Therefore, the flange portion 124 is required to overlap with the support portion 131 in the radial direction.

[0052] like Figure 3 and Figure 4As shown, the flange portion 124 and the support portion 131 clamp the stirring cup 11 axially, and the edge 123 and the side wall of the cup body bracket 13 clamp the stirring cup 11 radially, which can enhance the tightening effect of the stirring cup 11 and make the heating plate 12, the stirring cup 11 and the cup body bracket 13 more firm and compact.

[0053] In order to prevent liquid from flowing from the fitting gap between the heating plate 12 and the blending cup 11 into the cup body shell 14 below and damaging the internal electrical components, and to prevent materials or residues from being trapped in the fitting gap between the heating plate 12 and the blending cup 11 and causing odor, as a preferred embodiment, a sealing ring 18 is provided between the heating plate 12 and the step portion 111 to provide a reliable seal. Specifically, the heating plate 12 is provided with a rim 123 and a flange portion 124. In one embodiment, the sealing ring 18 is only clamped between the flange portion 124 and the step portion 111. In another embodiment, the sealing ring 18 includes a horizontal sealing portion clamped between the flange portion 124 and the step portion 111 and a vertical sealing portion clamped between the upper end of the rim 123 and the blending cup 11, which can enhance the sealing effect and effectively prevent liquid or residue from entering between the rim 123 and the blending cup 11. In addition to sealing, the sealing ring 18 can also achieve a soft connection between the heating plate 12 and the mixing cup 11, which is beneficial for a small floating adjustment of the heating plate 12 during the installation process to ensure the concentricity of the heating plate 12 and the mixing cup 11.

[0054] In order to improve the crushing effect of the material, as a preferred embodiment, the inner wall of the mixing cup 11 is provided with an axially extending spoiler rib 114, and the top of the heating plate 12 is not lower than the bottom of the spoiler rib 114. Figure 3 As shown, the bottom end of the spoiler rib 114 extends to the auxiliary crushing chamber 121. By optimizing the arrangement of the spoiler rib 114, it is beneficial for the material to be cut in the auxiliary crushing chamber 121 and then interact with the spoiler rib 114 as quickly as possible, which can increase the frequency of contact between the material and the spoiler rib 114, enhance the turbulent effect, and improve the crushing efficiency.

[0055] The heating plate 12 of the present application includes a heating plate body 125 and a heating tube 126 provided on the bottom wall of the heating plate body 125. The matching mode of the heating tube 126 and the heating plate body 125 can be flexibly set according to actual needs. The two can be set as one body or separately, so as to increase the flexibility of accessory processing. For example, in one embodiment, the heating tube 126 and the heating plate body 125 are integrally die-casted. In this way, the heat of the heating tube 126 is more efficiently transferred to the heating plate body 125, and the heat conduction effect is good. In another embodiment, the heating tube 126 is fixed to the heating plate body 125. For example, the heating tube 126 can be welded or fixed to the heating plate body 125 by mounting bracket screws. This method is less expensive.

[0056] The motor assembly 15 of the present application can be composed of a complete structure. For example, in one embodiment, the motor assembly 15 includes a motor upper cover, a motor body and a motor lower cover. The motor assembly 15 is flexibly suspended on the heating plate 12. The flexible suspension can reduce the vibration of the motor from being transmitted to the heating plate 12 and causing the heating plate 12 to loosen. This embodiment can be fixed with the motor upper cover and the heating plate 12. For example, the heating plate 12 is provided with a screw column extending downward, and the motor upper cover is provided with a mounting hole. A shock-absorbing pad is provided in the mounting hole. The motor assembly 15 can be installed by passing the screw column through the shock-absorbing pad and then locking the screw. In this embodiment, a heat dissipation gap is provided between the motor upper cover and the heating plate 12, which is beneficial to the heat dissipation of the motor assembly 15 and can reduce the heat transferred from the heating plate 12 to the motor assembly 15, thereby preventing the motor assembly 15 from overheating and affecting its performance and life.

[0057] Alternatively, in another embodiment, the motor assembly 15 includes a motor body and a motor lower cover, and the heating plate 12 and the motor lower cover jointly surround the motor body, so that the motor upper cover can be omitted, and the heating plate 12 can be reused as the motor upper cover, which can simplify the configuration of the motor assembly 15 and facilitate a more compact arrangement of the motor assembly 15 and the heating plate 12. Specifically, the bottom of the heating plate 12 is provided with an upper ring side wall extending downward, and the motor lower cover is provided with a lower ring side wall extending upward, and the upper ring side wall and the lower ring side wall cooperate to surround the motor body. Preferably, a gap is provided between the upper ring side wall and the lower ring side wall to meet the heat dissipation requirements of the motor assembly 15.

[0058] In a preferred embodiment, the motor of the motor assembly 15 of the present application can be a brushless motor. On the one hand, the brushless motor is small in size and light in weight, which can reduce the installation burden of the heating plate 12, which is beneficial to the stable operation of the cup body assembly 10. On the other hand, the flattening of the brushless motor can reduce the overall axial size of the cup body assembly 10, which is beneficial to the miniaturization and lightness of the entire machine.

[0059] Usually, the blade of the stirring blade assembly 16 is located at a certain height above the bottom of the heating plate 12. In order to prevent the stirring blade assembly 16 from shaking and causing unstable operation or even blade jamming when it is protruding too high, as a preferred embodiment, the heating plate 12 includes a chassis 122 and a boss 127 protruding upward from the center of the chassis 122, and the stirring blade assembly 16 is suspended above the boss 127.

[0060] like Figure 3As shown, the provision of boss 127 supports and limits the motor shaft 151, preventing the upper end of the motor shaft 151 from shaking and affecting the stability of the mixing blade assembly 16. Preferably, boss 127 is formed by a portion of the chassis 122 being raised upward during processing. A certain space is formed outside the boss 127 to accommodate the internal seal assembly and bearings, thereby improving space utilization. The installation height of the blade of the mixing blade assembly 16 ensures that the blade does not interfere with the boss 127, while also ensuring the stability of the blade's rotation.

It should be noted that the combination of the technical solutions of any one embodiment with the technical solutions of one or more other embodiments falls within the scope of protection of this utility model. Although the above description of this utility model has been provided in detail using general instructions and specific embodiments, it is obvious to those skilled in the art that modifications or improvements can be made based on this utility model. Therefore, such modifications or improvements made without departing from the spirit of this utility model are within the scope of protection claimed by this utility model.
