Abstract
Provided is a washing machine. The washing machine includes a tub, a drum, a pulsator, a water stream generation unit, a filter cap, and a check valve. The tub contains washing water. The drum is rotatably disposed in the tub and receiving laundry. The pulsator is rotatably disposed inside the drum and has a spouting outlet. The water stream generation unit is disposed under the pulsator and forms a water stream spouted through the spouting outlet by circulating washing water contained between the tub and the drum. The filter cap collects foreign substances floating in washing water spouted through the spouting outlet. The check valve opens the spouting outlet by the water stream formed by the water stream generation unit.
