Document Type and Number:
WIPO Patent Application WO/2021/109897
Kind Code:
A1
Abstract:
A heating circulation pump (6) and a washing machine, the heating circulation pump (6) comprising a pump shell (60), wherein the pump shell (60) is internally provided with a pump cavity (62) allowing water flow to flow, a driving device is mounted on the pump shell (60) and used for providing flowing driving force for the water flow in the pump cavity (62), a heating member (8) is arranged on the pump shell (60), at least part of the heating member (8) makes contact with water flowing in the pump cavity (62) and heats the water, and the heating member (8) and the inner wall of the pump shell (60) jointly form the smooth pump cavity (62). By means of the arrangement, the smooth pump cavity (62) is formed in the heating circulation pump (6), foreign matter such as thread scraps wrapped and clamped in the water flow flowing through the heating circulation pump (6) cannot accumulate in the pump cavity (62) and cannot be intercepted by the heating member (8) arranged in the pump cavity (62), achieving the effect that the water flow smoothly flows; and meanwhile, the heating member (8) is in direct contact with the water flow flowing through the pump cavity (62), such that the heating member (62) can directly conduct contact heating on the water flow flowing through the heating circulation pump (6), and the heating efficiency is markedly improved.
