Background

Traditional food processor especially broken wall machine utilizes motor drive to smash the cutter and smash the processing to edible material, sets up the heating member simultaneously and decocts edible material, has satisfied personnel's demand to edible material culinary art processing greatly. In order to provide the crushing effect of the food processor, the motor drives the crushing cutter to rotate at a high speed, but the high-speed operation of the motor increases the noise of the food processor and also increases the operating temperature of the motor itself. Therefore, how to effectively reduce the noise and the temperature rise of the motor is a technical problem faced by and needed to be solved by those skilled in the art.

Compared with the prior food processor, the motor is directly arranged in the shell of the host machine, the motor cover is generally sleeved outside the motor, a heat dissipation air channel is formed inside the motor cover, and when the motor works, the fan drives air flow to flow into the motor from one end of the motor cover and flow out from the other end of the motor cover. The CN202022829287.2 discloses a cooking machine, which comprises a motor, wherein the motor is provided with a fan, the motor is cooled by the fan, a motor cover is arranged outside the motor, and the motor cover forms an air channel. The motor cover can not only insulate sound and reduce noise, but also guide air flow and improve heat dissipation performance. However, the technical scheme can only meet the simple functional requirements, and the improvement of noise reduction and heat dissipation is not outstanding.

As an improvement and promotion of technology, heat dissipation and noise reduction of the motor are improved by changing the matching structure between the motor and the motor cover. As disclosed in CN201921024767.2, a food processor is provided with a motor cover outside the motor, the motor cover includes a coaming and an air duct member, a containing cavity is arranged in the coaming, and a main air duct is arranged in the air duct member.

According to the scheme, the closed motor cover is arranged, the closed accommodating cavity and the main air duct are formed, noise of the motor can be shielded in the closed accommodating cavity, and the main air duct can guide most air flow to the motor to improve the heat dissipation effect of the motor. However, the following technical problems still exist in such a scheme: because the motor cover needs to seal the motor and is provided with the air duct piece and the main air duct outside, the motor cover needs to occupy a larger volume in space, so that the volume of a host of the food processor is increased, the space which other components in the host can contain, such as a circuit board, is not beneficial to the assembly of the internal components of the host, the compression is not beneficial to the heat dissipation of the control board, and although the heat dissipation of the control board can be improved by arranging the auxiliary air duct, when the heat dissipation requirement of the main control board is increased, the heat dissipation of the control board is not beneficial to the sealed space between the motor cover and the shell; meanwhile, the closed main air duct and the accommodating cavity can guide most air flow to the motor, but the air flow needs to reciprocate in the air duct, the inner shape and the structure of the air duct can influence the speed and the direction of air flow, and further influence the heat dissipation effect of the motor cover on the motor.

In the research and development process of the product, the applicant continuously explores the assembly structure of the motor and the motor cover so as to achieve better noise reduction and heat dissipation effects. In the food processor of CN202222626564.9 and CN202223521497.0, a motor cover is arranged outside the motor to form a motor assembly together with the motor, and a cavity for defining the space of the motor is formed by using the motor assembly, so that the noise reduction and heat dissipation of the motor are fully improved.

However, the applicant found when intensively researching and fully analyzing the market performance of the product that, although the existing technical scheme can achieve better and stronger heat dissipation and noise reduction effects on the motor, the technical scheme needs a complex structure to support, and the structure generally occupies a larger space, and the complex structure enables the gas to continuously reciprocate in the motor cover, so that the final efficiency is affected.
