The present invention relates to a washing machine, capable of extracting microbubbles by decompressing and extracting gas dissolved in water, and effectively performing a cleaning effect by the microbubbles. A microbubble generating unit, installed in a water supply pipe supplying water into a tub, includes: a throttle part installed in a path connecting an inlet and an outlet, and making the area of the path smaller than the inlet; and a collision part to reduce the area of the path of the throttle part by dividing the path in the throttle part into multiple segment areas. After gas solution liquid, supplied from the inlet to the path, collides with the collision part, the liquid passes through the segment areas by being distributed to the segment areas after an increase in speed. Its decompressing effect extracts the dissolved gas to make microbubble-contained liquid, containing microbubbles. The microbubble-contained liquid is discharged from the outlet. The water, passing through the microbubble generating unit, is supplied into the tub through the water supply pipe. |
