Abstract

The invention discloses a fan of an outdoor unit of an air conditioner. The fan comprises a bearing and fan blades, wherein the central part of the bearing is fixedly connected with a motor shaft; the fan blades are fixedly connected to a side face of the bearing; the outer side of a front panel of the bearing sinks inwards to form a groove which is concentric with the front panel; and a washer is embedded in the groove. By using the washer, the vibration amplitude brought by the motor shaft is relieved, so that the noise is reduced; and the front panel is provided with uniformly distributed through holes, so that air circulation on the central part is increased, and the stability of blown air is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a fan structure of an outdoor unit of an air conditioner. Background technique [0002] An air conditioner is an electrical device that regulates and maintains the indoor temperature at the condition required by the user. The air conditioning function of the air conditioner is completed by the refrigeration circulation system and the air circulation system. The refrigerant circulating in the refrigeration system exchanges heat with the air flowing in the room to achieve indoor cooling or heating, and provide people with fresh and comfortable air. indoor air environment. [0003] The refrigerating cycle system of the air conditioner includes a heat exchanger, a compressor and throttling devices. The air circulation system includes a fan and a fan motor, an air inlet and outlet and an air filter. The operation of the refrigeration cycle system and the air cycle system o...
