Summary of the invention:

The purpose of this utility model provides a kind of volute of blower, and it is simple in structure, and cost is low, and drainage performance is good.

The purpose of this utility model is achieved by following technical proposals.

A kind of volute of blower is provided with intake grill and exhaust outlet, and volute of blower is provided with at least one weep hole, on the inwall of volute of blower, weep hole above both sides be provided with rib, rib is introduced weep hole with the condensed water that produces in the volute of blower and is discharged.

Above-mentioned described weep hole comprises inlet, drain opening and the diversion section between inlet, drain opening, and inlet, drain opening and diversion section three's shape of cross section and size are identical.

Above-mentioned described rib is arranged on the inlet side.

Above-mentioned described rib vertically connects the side edge of inlet.

The tubular body of volute of blower outside is extended in the peripheral formation one of above-mentioned described diversion section.

The outer installment stiffening rib of above-mentioned described tubular body.

Above-mentioned described volute of blower comprises cover body and circular bottom, and at the some assembly departments of the arranged outside of cover body, circular bottom and cover body be nested to be cooperated and be welded together or be sticked together.

Above-mentioned described intake grill is located at the middle part of circular bottom, and circular bottom directly embeds the circular inner wall the inside of cover body bottom, and circular inner wall is provided with step, and the top-supported of circular bottom is on step.

Side at cover body sets out the air port.

Above-mentioned described weep hole is arranged on the top side mural margin of cover body, and the shape of cross section of weep hole is a U-shaped.

The utility model compared with prior art, have following effect: 1) blower volute structure is simple, cost is low, on the inwall of volute of blower, weep hole above both sides be provided with rib, rib compiles the condensed water that produces in the volute of blower and introduces weep hole and discharge, and the drainage effect ideal has been guaranteed air stable performance in the blower, service time is of a specified duration, can not cause that also the combustion system of a whole set of blower fan system is extinguished; 2) volute of blower comprises cover body and circular bottom, at the some assembly departments of the arranged outside of cover body, circular bottom and cover body be nested to be cooperated and is welded together or is sticked together, linkage structure is simple, cost is low, cooperation is installed conveniently, firmly, has both realized the generalization of bottom, satisfied different clients again to the installation of volute of blower and the different requirements of steering position, greatly reduced and produce and administration cost.
