Abstract

The present invention relates to a drain pump for a clothes-handling apparatus, comprising: a housing for accommodating water; a water flowing part formed on the inner peripheral surface of the housing, and having an impeller for forming a flowing current of water or washing water such that the accommodated water or washing water circulates to a tub or is drained to the outside of a washing machine; a drain pump chamber formed on the inner peripheral surface of the housing so as to receive or store the water or the washing water before the water or the washing water flows into the water flowing part; and an inlet formed between the water flowing part and the drain pump chamber so as to protrude toward the water flowing part.

Description

technical field [0001] The present invention relates to a drain pump. In particular, the present invention relates to a drain pump installed in a clothes treating device, and relates to a drain pump for a clothes treating device for draining or circulating water or washing water flowing in from a drum. Background technique [0002] The laundry treatment device is a device that puts clothes, bedding, etc. (hereinafter referred to as laundry) inside the drum and removes stains attached to the laundry, and performs processes such as washing, rinsing, dehydration, and drying. [0003] Based on the method of loading laundry into the drum, the laundry treatment apparatus is classified into a top loading method and a front loading method. Generally, a washing machine of a front loading system is called a front-loading washing machine. [0004] figure 1 Shows the appearance of a front-loading washing machine, figure 2 show figure 1 The interior of the front-loading washing mach...
