[0021] In order to further explain the technical means and effects adopted by the present application to achieve the predetermined purpose, the specific implementation methods, structures, features and effects of the present application are described in detail below in conjunction with the accompanying drawings and preferred embodiments. In the following description, different "one embodiment" or "embodiment" does not necessarily refer to the same embodiment. In addition, specific features, structures, or characteristics in one or more embodiments may be combined in any suitable form.

[0022] like Figure 1-Figure 5 As shown, the present application discloses a food processor, including a cup holder 2, a motor 7 located in the cup holder 2, a cooking cup located on the cup holder 2, and a knife group (not shown in the figure) located in the cooking cup, the cooking cup including a cup body 3 and a heating plate 4 assembled at the bottom of the cup body 3, the center of the heating plate 4 has an axial hole 41, and an oil seal 8 is arranged in the axial hole 41; the top end of the motor 7 is fixedly assembled at the bottom of the heating plate 4, and the output shaft 71 of the motor 7 passes through the oil seal 8 upward and is connected to the knife group, and the oil seal 8 seals the axial hole 41 and the output shaft 71.

[0023] The present application discloses a food processor, which abandons the assembly structure of the prior art in which the motor is installed on the main body or the base through a bracket, and instead fixes the motor directly on the bottom of the heating plate 4 so that the motor 7 and the cooking cup form an integral structure, which not only simplifies the assembly accuracy requirements of the motor 7, but also ensures that the output shaft 71 of the motor 7 is always coaxial with the knife shaft of the knife group, avoiding the generation of large working noise when the two are not in the same axis due to the vibration of the motor 7. The smaller working noise is conducive to improving the user experience.

[0024] For example, a plurality of assembly columns 43 are provided at the bottom of the heating plate 4, and a plurality of first assembly holes 72 are correspondingly provided on the motor 7. The motor 7 is fixedly assembled at the bottom of the heating plate 4 by passing a fixing element (such as a screw) through the first assembly hole 72 and fixing it to the assembly columns 43 at the corresponding position.

[0025] Preferably, in order to improve the working reliability of the motor 7 and reduce the heat generated by the heating plate 4 and radiated to the motor 7, which causes the motor 7 to overheat and work unstably, a cup-shaped air duct 9 is further included, the motor 7 is placed in the cup-shaped air duct 9, and a heat dissipation air duct is formed by a gap between the inner wall of the cup-shaped air duct 9 and the motor 7. For example, the cup-shaped air duct 9 is provided with a second assembly hole 91, and the fixing element is fixed through the second assembly hole 91, the first assembly hole 72 and the assembly column 43 at the corresponding position in sequence, so that the cup-shaped air duct 9 and the motor 7 can be fixedly assembled at the bottom of the heating plate 4, and the assembly is simple and the assembly accuracy requirement is low.

[0026] An air inlet is provided at the lower end of the cup holder 2 corresponding to the cup-shaped air duct 9. Usually, a fan close to the air inlet is provided at the lower end of the output shaft 71 of the motor 7. When the motor is working, the fan rotates synchronously, and when external cold air is sucked in from the air inlet and flows through the heat dissipation duct, it plays a role in dissipating heat and cooling the motor 7.

[0027] The heating plate 4 is usually made of a metal material with good thermal conductivity, basically harmless to the human body and relatively low cost, such as aluminum integral die-casting. The heating plate 4 includes a plate body and a plate wall extending upward from the circumference of the plate body. The plate wall and the plate body enclose an inwardly concave processing cavity, and the knife group is located in the processing cavity.

[0028] It is understandable that an electric heating element, such as a heating wire or a heating tube, is provided on the bottom side of the plate body and / or the outer side of the plate wall, so that the heating plate 4 can heat the ingredients in the cooking cup as needed.

[0029] Preferably, at least the lower end of the plate wall has a converging inner wall 42 that converges from top to bottom toward the shaft hole 41, so that the size of the processing cavity converges from top to bottom. The processing cavity has a smaller space, which not only allows the knife set to be used to process a small amount of food, but also helps the food to roll during the processing, which helps to improve the processing efficiency and the processing effect.

[0030] The inner side of the dish wall is provided with spoiler ribs, which are used to block the food in the processing cavity, so that turbulence is generated in the food during the tumbling process, thereby increasing the tumbling chance and improving the processing effect.

[0031] The top of the plate wall of the heating plate 4 is fixedly connected to the bottom of the cup body 3. For example, a first sealing ring 61 is provided between the bottom of the cup body 3 and the top of the plate wall, and the bottom of the cup body 3 and the top of the plate wall are fixedly assembled by a limiting ring 5, which is sleeved on the outer side surface of the junction between the bottom of the cup body 3 and the top of the plate wall to provide limiting support, and the limiting ring 5 presses the first sealing ring 61 to seal the junction between the bottom of the cup body 3 and the top of the plate wall.

[0032] A second sealing ring 62 is further provided between the top end of the limiting ring 5 and the cup body 3 , and the second sealing ring 62 is used to form a secondary seal to improve the sealing performance between the bottom end of the cup body 3 and the top end of the disk wall.

[0033] A plurality of buckles 31 are provided at the bottom end of the cup body 3, and a plurality of rotary buckles 51 are correspondingly provided at the upper end of the inner wall of the limiting ring 5. The limiting ring 5 and the cup body 3 can be fixedly assembled by fastening the buckles 31 with the rotary buckles 51 at corresponding positions.

[0034] At the same time, a supporting step 52 is correspondingly provided at the lower end of the inner wall of the limiting ring 5, and a limiting skirt 49 is correspondingly provided at the heating plate 4. After the lower end of the heating plate 4 passes through the limiting ring 5 from top to bottom, the limiting skirt 49 abuts against the supporting step 52 to play a positioning and limiting role.

[0035] The cooking cup adopts a structure in which the cup body 3 and the heating plate 4 are connected, so that the cup body 3 and the heating plate 4 can be separately formed and processed, and the cup body 3 is made of different materials. Usually, the cup body 3 is made of a healthy and easy-to-wash glass cup.

[0036] Another example Figure 1 and Figure 2 As shown, the food processor further includes a soundproof cover, which includes a cover seat 11 and a cover body 12 disposed on the cover seat 11. The cup holder 2 and the cup body 3 are fixedly assembled to form an integral structure, which can be put into or taken out of the soundproof cover as a whole, and the soundproof cover is used to further reduce working noise.

[0037] Of course, the top of the cooking cup has a cup cover 13 with an exhaust passage 14 , and at least the exhaust passage 14 is exposed outside the cover body 12 .

[0038] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
