TECHNICAL FIELD

[0001] The present application relates to the field of small household appliances, in particular to a food processor. BACKGROUND

[0002] With the increasing improvement of people's living standards, many different types of food processors appear on the market. The functions of the food processor mainly can include, but are not limited to, making soy milk, juicing, making rice paste, mincing meat, shaving ice, making coffee and / or mixing mask, etc. The food processor can include a soy milk maker, a blender or a blender, etc. The direct drive type food processor sets the motor at the bottom of the stirring cup assembly, the output shaft of the motor penetrates the bottom disc, and the blade is fixed at the top end of the output shaft, so as to reduce the noise generated during the operation of the food processor. However, due to the large size of the traditional motor, the existing direct drive type food processor is too high and heavy, which affects the appearance and is not convenient to clean. CONTENT OF THE UTILITY MODEL

[0003] The purpose of the present application is to provide a food processor which can reduce noise while maintaining low height and light weight, so that the overall appearance of the food processor is more beautiful and easier to clean.

[0004] The present application provides a food processor. The food processor comprises: a stirring cup assembly comprising a stirring cup and a bottom disc arranged at the bottom end of the stirring cup, the bottom disc comprising a disc body and a boss protruding upward from the disc body, the boss surrounding to form a receiving cavity with a lower opening and a through hole communicating with the receiving cavity; a brushless motor assembled on the bottom disc, the brushless motor comprising a motor body and a rotating shaft, the motor body extending upward into the receiving cavity, the motor body comprising an inner stator assembly and an outer rotor assembly arranged outside the inner stator assembly, the rotating shaft being fixed to the outer rotor assembly, and the rotating shaft extending out of the through hole; and a stirring blade detachably mounted on the rotating shaft. Since the brushless motor does not include a brush and a commutator, the brushless motor has the characteristics of small height and light weight, thereby effectively reducing the overall height and weight of the food processor, making the appearance of the food processor more simple, and cleaning more labor-saving; since the bottom disc comprises a disc body and a boss protruding upward from the disc body, the boss surrounds to form a receiving cavity with a lower opening, and the motor body extends upward into the receiving cavity, that is, the motor body is at least partially located in the receiving cavity, only a smaller space is needed below the bottom disc to accommodate the brushless motor, so as to further reduce the height of the stirring cup assembly; at the same time, since the stirring blade is detachably mounted on the rotating shaft, after the use of the food processor is finished, the stirring blade can be detached, and the stirring blade and the stirring cup assembly can be cleaned respectively, so that the cleaning is more thorough and the hands are protected.

[0005] Further, the rotating shaft comprises a driving section, the driving section comprises a plurality of convex edges extending along the up-down direction, the plurality of convex edges gradually deflect along the circumferential direction of the driving section, and the deflection direction of the plurality of convex edges from bottom to top is opposite to the rotating direction of the rotating shaft, and the stirring blade comprises a driving hole matched with the driving section, the driving hole comprises a plurality of convex corners vertically extending along the up-down direction. In this way, the convex edges deflecting along the circumferential direction of the driving section have a downward limiting effect on the stirring blade, so that the stirring blade cannot be separated from the rotating shaft along the axial direction upward in high-speed rotation.

[0006] Further, the rotating shaft comprises a main shaft section and the driving section is manufactured into a shape and fixed together. In this way, the main shaft section and the driving section are manufactured into a shape respectively, which is simpler to process and lower in cost.

In this way, the structure is simple and reliable.

[0010] Further, the upper surface of the motor body is flush with the upper surface of the disc body, or the upper surface of the motor body is higher than the upper surface of the disc body. In this way, only part of the motor body is located below the disc body, and the blender cup only needs a smaller space below the disc body to accommodate the brushless motor, so that the height of the blender cup can be further reduced, and the appearance of the food processor is more beautiful.

[0011] Further, the brushless motor is installed on the disc body through a motor support, the motor support comprises a support body and a first mounting portion, the brushless motor is fixed to the support body, and the mounting portion is fixed to the disc body. In this way, the brushless motor can be conveniently and reliably installed on the disc body. The inner stator assembly comprises a stator fixing frame, a coil winding assembled on the stator fixing frame, and a motor support formed in one body with the stator fixing frame, and the brushless motor is installed on the disc body through the motor support. In this way, the brushless motor can be conveniently and reliably installed on the disc body, and the structure is simpler.

[0012] Further, the stirring cup assembly comprises an upper coupler electrically connected with the brushless motor, the food processor comprises a base, the base comprises a shell, a control circuit board arranged in the shell and a lower coupler electrically connected with the control circuit board, when the stirring cup assembly is assembled on the base, the upper coupler and the lower coupler are docked to form an electrical connection. Since the control circuit board is arranged in the base, the stirring cup assembly is lighter in weight, and it is more convenient and labor-saving to clean. The stirring cup assembly comprises a control circuit board arranged in the stirring cup, and the control circuit board is electrically connected with the brushless motor. In this way, the control circuit board is arranged in the stirring cup, so that the base does not need to be arranged, and the overall structure of the food processor is simpler and the cost is lower.

[0013] Further, the outer diameter of the brushless motor is between 20 mm and 75 mm, and the height of the brushless motor is between 20 mm and 75 mm. In this way, on the one hand, the brushless motor can provide sufficient power to drive the stirring knife to stir and crush the food materials, and on the other hand, the volume and weight of the brushless motor are small, which can not only ensure the appearance of the food processor, but also facilitate cleaning. The stirring cup comprises a cup body and a cup seat arranged at the bottom end of the cup body, and the height of the cup seat is between 20 mm and 100 mm. In this way, the appearance of the stirring cup assembly is more beautiful, and the size of the cup seat can be better matched with the brushless motor. BRIEF DESCRIPTION OF DRAWINGS
