Abstract

The invention relates to the field of ventilation equipment, and is used for a plastic air supply device for an air conditioner. The plastic air supply device for the air conditioner includes an annular leaf baseplate, a wheel hub, a stream guiding ring and multiple blades. The outer diameter of the annular leaf baseplate ranges from 420 mm to 480 mm; the inner diameter size is 75%-85% of the outer diameter size of the annular leaf baseplate, and the shape from an air inlet end of each blade to an air outlet end of the blade is distorted; an upper air inlet angle is different from a lower air inlet angle and both angles are not greater than 10 degrees. An air outlet angle is different from an air outlet angle and both angles range from 20 degrees to 45 degrees. The upper portion of the blade is formed by a connection area and a disconnection area, wherein the connection area and the disconnection area are connected in an integrated mode. The air inlet area between any adjacent blades is 66%-75% of a corresponding air outlet area. The plastic air supply device for the air conditioner has the advantages of being novel in structure, huge in air volume and low in noise.

Description

technical field [0001] The invention relates to the field of ventilation equipment, in particular to a plastic air supply device for air conditioners. Background technique [0002] The plastic air supply device used in the air conditioner is a commonly used product in the field of ventilation equipment. The plastic air supply device used in the air conditioner includes a circular leaf base plate, a hub, blades and a guide ring, and the blades are fixed on the circular leaf base plate. Between the hub and the guide ring, the hub is integrated with the inner side of the circular blade bottom plate, the hub and the circular blade bottom plate are concentric, and a shaft sleeve is set at the center of the top of the hub. The leaves turn. The performance of the plastic air supply device used in air conditioners is mainly reflected in the air volume and noise control. The air volume and the noise level are mutually related. Generally, the noise is relatively high when the air vol...
