Abstract (en)

A heating apparatus of a washing machine comprises: a steam generator for generating steam; and a spray nozzle for spraying steam generated from the steam generator into a tub, in which a water level sensor for detecting a level of water supplied for steam generation step by step is mounted at the steam generator. According to this, an entire size of the washing machine is reduced, an amount of washing water is reduced, and a water level inside the steam generator is detected more accurately, thereby enhancing a performance of the heating apparatus. <IMAGE>
