[0031] Figure 1 The diagram is a plan view of a food processor 10 according to an embodiment of the present application; Figure 2 Shown Figure 1 An exploded perspective view of the food processor 10 is shown; Figure 3 Shown Figure 1 The blending cup assembly 12 of the food processor 10 is shown in FIG. Figure 1 , Figure 2 and Figure 3As shown, the food processor 10 may be a wall-breaking machine, a soymilk machine, etc. The food processor 10 includes a host 11 and a mixing cup assembly 12. The host 11 may provide electrical energy to control the food processor 10 to work. The host 11 may be in the form of a machine base. The mixing cup assembly 12 is disposed on the host 11, and the mixing cup assembly 12 may be detachably disposed on the host 11, and the mixing cup assembly 12 may be disassembled for cleaning.
[0032] The mixing cup assembly 12 includes a mixing cup 13 and a heating plate assembly 14. The mixing cup 13 can be used to hold ingredients to be whipped, and operations such as crushing ingredients and heating can be performed in the mixing cup 13. The heating plate assembly 14 can be used to whip and heat ingredients. The heating plate assembly 14 is arranged at the bottom of the mixing cup 13. The heating plate assembly 14 is detachably arranged at the bottom of the mixing cup 13. In some embodiments, the mixing cup assembly 12 also includes a mixing cup holder 15, which is detachably arranged at the bottom of the mixing cup 13, and the mixing cup holder 15 can be threadedly connected to the mixing cup 13. The heating plate assembly 14 is clamped between the mixing cup holder 15 and the mixing cup 13, so that the heating plate assembly 14 is detachably arranged at the bottom of the mixing cup 13. This facilitates the installation and removal of the heating plate assembly 14.
[0033] In some embodiments, the blending cup assembly 12 further includes a blending cup cover 16, and the blending cup cover 16 can be covered on the blending cup 13. The blending cup cover 16 is covered on the blending cup 13 to prevent the ingredients from splashing and polluting the environment.
[0034] Figure 4 Shown Figure 1 The cross-sectional view of the blending cup assembly 12 of the food processor 10 is shown with the blending cup cover removed; Figure 5 Shown Figure 1 The heating plate assembly 14 of the food processor 10 is shown. Figure 6 Shown Figure 5 The manner in which the plurality of heating elements 22 of the heating disk assembly 14 are connected in series; Figure 7 Shown Figure 5 The multiple heating elements 22 of the heating plate assembly 14 are connected in parallel. Figure 4 and Figure 5As shown, the heating plate assembly 14 includes a heating assembly 17 and a stirring blade assembly 18. The heating assembly 17 can be used to heat the food slurry. The stirring blade assembly 18 can whip the food to make a slurry. The stirring blade assembly 18 rotates to achieve the whipping of the food. The heating assembly 17 includes a heat-conducting plate 21 and a heating element 22. The heat-conducting plate 21 can transfer the heat of the heating element 22, and the material of the heat-conducting plate 21 can be aluminum. The heating element 22 can be arranged on the surface of the heat-conducting plate 21. The heating element 22 generates heat to heat the food. When the heating plate assembly 14 is applied to the food processor 10, the mixing cup 13 and the heating assembly 17 are enclosed to form a receiving space 23. Among them, the mixing cup 13 and the heat-conducting plate 21 of the heating assembly 17 are enclosed to form a receiving space 23. The stirring blade assembly 18 is located in the receiving space 23. The receiving space 23 can accommodate food, and the stirring blade assembly 18 can whip the food in the receiving space 23.
[0035] The heat conducting plate 21 includes a bottom wall 24 and a side wall 25 extending outwardly from the edge of the bottom wall 24. The angle between the side wall 25 and the bottom wall 24 can be an acute angle, an obtuse angle or a right angle, which is not limited in this application. The heat conducting plate 21 can be bowl-shaped, so that more food can be accommodated. The stirring blade assembly 18 is arranged on the bottom wall 24. The heating element 22 is arranged on the side wall 25. In this way, the food can be precipitated on the bottom wall 24, thereby preventing the occurrence of the bottom sticking phenomenon. In some embodiments, the heating element 22 includes any one or more of the following: heating wire, heating film, coil. There is no need to set a large heating tube, but a small heating wire, heating film, coil and other types are used. Such a simple structure and a small volume of the heating element 22 make the heating plate assembly 14 more lightweight. When the heating plate assembly 14 is applied to the food processor 10, such a setting can reduce the lateral or longitudinal dimensions of the heating plate assembly 14, thereby reducing the center of gravity of the mixing cup assembly 12 as a whole, so that the food processor 10 is not easy to shake during operation and has low noise. The volume of the blending cup assembly 12 can be set smaller, so that it is easy to carry. When the heating element 22 includes a heating wire, the heating wire can be integrally die-cast with the heat-conducting plate 21. When the heating element 22 includes a heating film, the heating film can be attached to the surface of the heat-conducting plate 21. Figure 6 and Figure 7 As shown, there are multiple heating elements 22, and the multiple heating elements 22 are arranged at intervals along the circumference of the heat conducting plate 21. The multiple heating elements 22 can be arranged at even intervals along the circumference of the heat conducting plate 21. In this way, the heat generated by the multiple heating elements 22 is more uniform, the heating efficiency is high, and there is no defect of hot and cold ends. The multiple heating elements 22 are connected in series and / or in parallel. The multiple heating elements 22 can be connected in series (such as Figure 6As shown). Multiple heating elements 22 are connected in series, and the start and stop of multiple heating elements 22 can be controlled at the same time, thereby facilitating the control of multiple heating elements 22. Starting multiple heating elements 22 at the same time can achieve a more uniform heating effect. Multiple heating elements 22 can also be connected in parallel (as shown). Figure 7 As shown). Multiple heating elements 22 are connected in parallel, and the start and stop of the multiple heating elements 22 can be controlled separately, so that it can adapt to various heating conditions.
[0036] In a heating plate assembly 14 of one embodiment of the present application, a plurality of heating elements 22 are arranged at intervals along the circumference of a heat conducting plate 21, and the plurality of heating elements 22 are connected in series and / or in parallel. In this way, heating can be achieved through the plurality of heating elements 22. Compared with setting a heating tube, the heat generated by the plurality of heating elements 22 is more uniform and the heating effect is better.
[0037] See also Figure 7 As shown, in some embodiments, at least two heating elements 22 among the plurality of heating elements 22 are connected in series to form a heating element group 30, and the plurality of heating elements 22 form a plurality of heating element groups 30. Among them, at least one heating element 22 is spaced between two connected heating elements 22 in a heating element group 30. Two heating elements 22 in a heating element group 30 may be spaced apart by one, two or more heating elements 22 and connected in series. Among them, two different connected heating elements 22 may be spaced apart by the same number of heating elements 22, or by different numbers of heating elements 22. In this way, during the heating process, when the heating element group 30 is called to work, one side of the heat conducting plate 21 may not need all the heating elements 22 to be heated, and only part of the heating elements 22 may be used for heating, so that the heating power can be saved while ensuring the heating effect.
[0038] In some embodiments, multiple groups of heating element groups 30 are connected in parallel. Heating can be achieved by calling one group of heating element groups 30 or multiple groups of heating element groups 30, which can be adapted to a variety of heating conditions and has a good heating effect. According to the requirements of food materials and heating power, one group of heating element groups 30 or multiple groups of heating element groups 30 can be operated to achieve the heating of food slurry. For example, when the concentration of the cooking food slurry is low and the amount of food is small, full power heating can be used, and all heating element groups 30 can be turned on for heating, with fast heating speed and high heating efficiency. One of the heating element groups 30 can be called to maintain the temperature before the food is boiled.
[0039] In some embodiments, the stirring blade assembly 18 includes a stirring blade shaft 19 and a stirring blade 20 disposed on the stirring blade shaft 19. The stirring blade 20 is fixedly disposed on the stirring blade shaft 19. The stirring blade shaft 19 rotates, which can drive the stirring blade 20 to rotate to achieve the whipping of the food. Among them, the stirring blade shaft 19 of the stirring blade assembly 18 can be assembled on the bottom wall 24. The projection of the stirring blade 20 on the side wall 25 is at least partially located within the coverage range of the heating element 22 in the axial direction of the stirring blade shaft 19, so that during the rotation and whipping process of the stirring blade assembly 18, the food can be stirred in time to prevent the food from adhering to the side wall 25, thereby reducing or eliminating the occurrence of sticky bottom, and providing a good user experience.
[0040] In some embodiments, the heating plate assembly 14 also includes a separator plate 26 disposed on the inner side of the heat-conducting plate 21. The separator plate 26 includes a main body 27 and an edge portion 28, and the edge portion 28 extends radially outward from the edge of the main body 27 along the stirring blade shaft 19. The main body 27 can be used to hold food. The main body 27 is pressed against the inner surface of the heat-conducting plate 21, and the separator plate 26 is provided for contacting the food, which can meet the needs of food processing. In some embodiments, the mixing cup assembly 12 includes a sealing ring 29. When the heating plate assembly 14 is disposed at the bottom of the mixing cup 13, the sealing ring 29 is clamped between the bottom of the mixing cup 13 and the edge portion 28, and the edge portion 28 is used to press against the sealing ring 29, so as to prevent the slurry from leaking.
[0041] Main references Figure 5 As shown, in some embodiments, multiple heating elements 22 are arranged in multiple rows along the axis direction of the stirring blade shaft 19. Multiple heating elements 22 can be arranged in two, three or more rows along the axis direction of the stirring blade shaft 19. Different rows of heating elements 22 can be designed according to the area of the side wall 25 of the heat conducting plate 21. In this way, the heating area of the heating element 22 is larger, the heating speed is faster, and multiple heating elements 22 are arranged in multiple rows at intervals, so that the heating is more sufficient. Multiple rows of heating elements 22 are connected in parallel. For example, multiple heating elements 22 in the first row can be connected in series, multiple heating elements 22 in the second row can be connected in series, and the first row of heating elements and the second row of heating elements are connected in parallel. In this way, at least one row of multiple rows of heating elements 22 can be selectively started according to the requirements of food and heating power, so that precise heating can be achieved. Any row of heating elements 22 or multiple rows of heating elements 22 can be started to achieve single-sided or multi-sided heating, faster heating efficiency and more uniform heating. For example, when cooking relatively viscous ingredients in large quantities, a row of heating elements 22 that is farther from the ingredients can be selected for heating, thereby preventing the bottom of the heat conducting plate 21 from being scorched by excessive accumulation of ingredients during the heating process.
[0042] In some embodiments, the number of the stirring blades 20 is multiple. In this embodiment, the number of the stirring blades 20 is four. Among them, some stirring blades 20 extend upward at an angle, and some stirring blades 20 extend downward at an angle, so that the ingredients are more fully whipped. The projection of the one closest to the bottom wall 24 and the one farthest from the bottom wall 24 among the multiple stirring blades 20 on the side wall 25 is at least partially located within the coverage range of the heating element 22 in the axial direction of the stirring blade shaft 19. The projection of the one closest to the bottom wall 24 and the one farthest from the bottom wall 24 among the multiple stirring blades 20 on the side wall 25 can be at least partially located within the coverage range of the heating element 22 in the same row in the axial direction of the stirring blade shaft 19, or can be at least partially located within the coverage range of the heating element 22 in two different rows. In this way, the heating element 22 can be matched with the stirring blade 20, and the ingredients can be fully stirred to prevent the ingredients from adhering to the side wall 25, and the effect of reducing or eliminating the sticky bottom is good.

Figure 8 and Fig. 9 As shown, in this embodiment, the heating element 22 includes a heating wire, and the heating wire is in a spiral shape, so that the heating wire heats more evenly. The number of turns of the heating wire can be adjusted to adapt to the side wall 25 of the heat conducting plate 21 of different sizes, and a larger number of heating wire turns can be used to improve the heating efficiency.
[0044] In some other embodiments, the heating element 22 includes a heating film, which is in the form of a sheet. The heating film can be in the shape of a round sheet, a square sheet, etc. This arrangement makes the heating of the heating film more uniform. The area of the heating film can be adapted to the area of the side wall 25 of the heat conducting plate 21.
[0045] In some other embodiments, the heating element 22 includes a coil, and the coil is in a spiral shape. Such a configuration makes the heating of the coil more uniform, and the heating power of the coil is high, and the heating effect is good.
