Abstract

The present invention provides a drain pump capable of suppressing the influence of foreign matter contained in drain water. A drain pump (1) has a casing (10) having a suction pipe (16) extending downward, and a motor (40) that rotates a rotating blade housed in the casing (10). In addition, the drain pump (1) has an annular base (51) arranged so as to surround the suction pipe (16), and a catcher (55) provided on the upper surface of the base (51). In addition, the capturing part (55) has a mesh member extending in the circumferential direction of the suction pipe (16).

Description

technical field [0001] The present invention relates to a drainage pump which sucks water from a suction port and discharges it from a discharge port through rotating blades. Background technique [0002] The air conditioner installed on the indoor ceiling has a drain pan for receiving the drain water condensed on the surface of the indoor heat exchanger, and a drain pump (drain water pump) for discharging the drain water in the drain pan. [0003] The humidity around the drain pan is high, and bacteria are prone to multiply. Therefore, in the drain pan, a highly viscous sludge called slime may be generated due to spoilage of drain water, growth of bacteria, and the like. If the slime adheres to the rotating blades or blocks the suction port and the discharge port, the performance of the drain pump will decrease and cause a failure. [0004] An example of a conventional drain pump is disclosed in patent document 1. In this drain pump, the growth of bacteria is suppressed ...
