WASHING MACHINE

摘要

A washing machine is provided to implement a bubble-generating unit by improving a circulation flow path without separate devices and generate many bubbles in a short time by changing the extension part of a venturi tube for the smooth inflow of air. A washing machine comprises: a water tub storing water; a circulating pump circulating the water stored in the water tub; and a circulation flow path(45) guiding the water discharged from the circulating pump to the water tub. The circulation flow path has an expand member in which low air pressure is formed with the expansion of the flow path. The expand member comprises; an intake hole(51); and a venturi tube(50) in which inside diameter is reduced and expanded. The venturi tube comprises: a contraction part(55) in which the inside diameter is gradually reduced; an expansion part(56) in which the inside diameter is sharply expanded; an inflow part(52) connected to the contraction part; and an outflow part(54) connected to the expansion part.
