Description

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 blending 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 easy 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 middle position of the disc body, the boss surrounding to form a receiving cavity with an opening below, and the boss being provided with 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 fixed to 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 an opening below, 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.

[0005] Further, the stirring blade is fixed to the top end of the rotating shaft by fasteners or riveting or welding. In this way, the stirring blade can be conveniently and reliably fixed to the rotating shaft.

[0006] Further, the rotating shaft and the boss are sealed by an oil seal. In this way, water leakage is avoided.

[0007] Further, the boss comprises a first boss connected with the disc body and a second boss connected with the first boss, the first boss surrounds to form a containing cavity, and the second boss surrounds to form an oil seal containing cavity, and the oil seal is located in the oil seal containing cavity. In this way, the oil seal is well positioned, and the structure is simple and convenient to assemble.

[0008] Further, the outer rotor assembly comprises a rotor support, a magnet group and a positioning end cover, the magnet group is arranged in the rotor support, the positioning end cover is fixed to the top end of the rotor support, the magnet group is positioned in cooperation with the positioning end cover, and the rotating shaft penetrates through the positioning end cover and is fixed to the positioning end cover through a shaft sleeve. In this way, the structure is simple and reliable.

[0009] 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, and the blender cup only needs a smaller space below the disc to accommodate the brushless motor, thereby further reducing the height of the blender cup and making the appearance of the food processor more beautiful.

[0010] Further, the brushless motor is installed on the disc 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. In this way, the brushless motor can be conveniently and reliably installed on the disc. 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 through the motor support. In this way, the brushless motor can be conveniently and reliably installed on the disc, and the structure is simpler.

[0011] Further, the blender cup assembly comprises an upper coupler electrically connected with the brushless motor, the food processor comprises a base, the base comprises a housing, a control circuit board arranged in the housing, and a lower coupler electrically connected with the control circuit board, and when the blender 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 weight of the blender cup assembly is lighter, and cleaning is more convenient and labor-saving.

[0012] Further, the blender cup assembly comprises a control circuit board arranged in the blender cup, and the control circuit board is electrically connected with the brushless motor. In this way, the control circuit board is arranged in the blender cup, so that there is no need to arrange the base, thereby making the overall structure of the food processor simpler and the cost lower.

[0013] Furthermore, 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. This allows the brushless motor to provide sufficient power to drive the mixing blades to blend and pulverize the ingredients, while its small size and weight ensure both an aesthetically pleasing appearance and easy cleaning of the food processor. The mixing cup includes a cup body and a cup base located at the bottom of the cup body, with the height of the cup base between 20 mm and 100 mm. This results in a more aesthetically pleasing mixing cup assembly, and the dimensions of the cup base are well-matched to the brushless motor. Attached Figure Description
