Abstract (en)

A drum-type washing machine (100) having a water level sensing unit (50) prevents a water level sensing hose (51) from being damaged or broken, which allows a water level to be precisely detected. Further, the drum-type washing machine prevents the water level sensing hose from being clogged with impurities. The drum-type washing machine includes a water tub (20) to contain water therein, and the water level sensing unit (50) to detect a level of the water contained in the water tub. The water level sensing unit includes the water level sensing hose (51) to communicate with the water tub, and a water level sensor (54) to detect a pressure in the water level sensing hose and the level of the water contained in the water tub. The water level sensing hose is mounted to be spaced apart from the water tub. <IMAGE>
