Embodiment Construction

[0021] In order to describe in detail the technical features of the present invention, the following preferred embodiment is given and described as follows in conjunction with the accompanying drawings, wherein:

[0022] Such as Figure 1 to Figure 3 As shown, a drainage impeller 10 provided by a preferred embodiment of the present invention is mainly composed of an axis 11, an annular bottom plate 21 and an annular wall 31, wherein:

[0023] One end of the shaft 11 has a connecting groove 13 for connecting to a drive shaft 90 . The shaft 11 extends radially outwards with a plurality of supporting ribs 15 ; thereby achieving the water-repelling effect of the present invention.

[0024] The annular bottom plate 21 is arranged on the bottom of the plurality of supporting ribs 15, and the annular bottom plate 21 is separated from the axis 11 by a predetermined distance, so that the axis 11, the plurality of supporting ribs 15 and the annular bottom plate 21 A plurality of hollow...

Abstract

The invention discloses a drainage impeller. The drainage impeller comprises a shaft center, an annular bottom plate and an annular wall surface, wherein a connecting groove is formed in one end of the shaft center, the connecting groove is used for being connected with a driving shaft, and a plurality of supporting ribs extend outwards in the radial direction from the shaft center; the annular bottom plate is arranged at the bottoms of the supporting ribs, and the annular bottom plate is separated from the shaft center by a preset distance to enable a plurality of hollow parts to be formed between the shaft center, the plurality of supporting ribs and the annular bottom plate; the bottom surface of the annular bottom plate takes a wave shape; and the annular wall surface is provided withan upper edge and a lower edge, the annular wall surface is connected to the outer ends of the supporting ribs and is connected with the annular bottom plate through the lower edge of the annular wallsurface, wherein the upper edge takes a wave shape, and the lower edge takes a wave shape.

Description

technical field [0001] The invention relates to a drainage device, in particular to a drainage impeller. Background technique [0002] The air-conditioning drainage motor will generate noise, which is partly caused by the vibration caused by the resistance generated by the impeller hitting the air bubbles entrained in the condensed water, or the sound caused by the bursting of the air bubbles caused by the impact; therefore, if the impeller can be reduced The impact force on the air bubbles can effectively reduce the noise generation. [0003] Please refer to China Taiwan Patent No. I499724 to provide a drainage pump, which can divide the large-diameter impeller into inner and outer impellers, and through the alternate configuration of the inner and outer impellers, when the vortex is formed, the air bubbles will rotate in the direction of rotation. The downstream side escapes to reduce the impact on the impeller, and reduce the noise caused by the bubble burst and the vibr...
