Abstract
Disclosed is a washing machine having a bubble generator to wash laundry using bubbles. The washing machine includes a tub to contain washing water; and a bubble generator generating bubbles and supplying the bubbles to the tub, the bubble generator including a bubble generation pump allowing the washing water to flow therethrough and an ejector unit formed at one side thereof to mix air with the washing water. The washing machine minimizes a reduction of the speed of the washing water due to a passage resistance, and thus increases an amount of generated bubbles.
