Problems solved by technology

[0003] The air volume blown by the fan assembly in the related art is small and the noise is large
Although the air supply volume can be increased by increasing the speed of the motor, this leads to greater noise of the fan assembly, and the high speed of the motor increases the loss of the motor, increases the cost, and reduces the reliability and safety
In addition, when the air volume is not enough, a large-diameter impeller is sometimes used to solve the problem. This will not only increase the volume of the fan component itself, but also increase the overall volume of the household appliances. Moreover, considering that the large-diameter impeller is easy to deform under high temperature, this There are higher requirements for the material of the large-diameter impeller, and stricter requirements for the adjustment of dynamic balance, resulting in an increase in material costs and installation costs

Abstract

The invention discloses a draught fan assembly and a domestic electric appliance with the draught fan assembly. The draught fan assembly comprises a motor support, a motor, impellers and a flow collecting structure. A through hole is formed in the motor support. The motor is fixed to the front side of the motor support. The impellers are located in the through hole and connected with a motor shaft of the motor. The flow collecting structure is arranged on the motor support and corresponds to the through hole. The rear end face of the flow collecting structure is located on the rear side of the rear surface of the motor support. The height of the impellers is B, and the distance between the rear edges of the impellers and the rear end face of the flow collecting structure is L, wherein L is larger than or equal to 5% of B and smaller than or equal to 30% of B. According to the draught fan assembly, the air discharging amount of the fan assembly is better improved, and noise is lowered.

Description

technical field [0001] The invention relates to the technical field of household electrical appliances, in particular to a fan assembly and a household electrical appliance having the same. Background technique [0002] Generally, a fan is usually provided in a household appliance to facilitate heat dissipation of the household appliance. [0003] The air volume blown by the fan assembly in the related art is small and the noise is large. Although the air supply volume can be increased by increasing the speed of the motor, this leads to greater noise of the fan assembly, and the high speed of the motor increases the loss of the motor, increases the cost, and reduces the reliability and safety. In addition, when the air volume is not enough, a large-diameter impeller is sometimes used to solve the problem. This will not only increase the volume of the fan component itself, but also increase the overall volume of the household appliances. Moreover, considering that the large-...
