Problems solved by technology

[0007] However, in the existing washing machine, a space for accommodating the heater 130 for heating clothes must be provided at the lower portion of the washing tub 104, so that the overall size of the washing machine becomes large.
And, because washing water also must be arranged at the position that accommodates heater 130, thereby will be huge for the waste of washing water
[0008] Moreover, the washing water is heated by the heater 130, thereby increasing the power consumption of the heater, increasing the amount of detergent, and prolonging the washing time

Abstract

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.

Description

technical field [0001] The present invention relates to an apparatus for heating laundry in a washing machine, and more particularly, to an apparatus for heating laundry by spraying steam directly onto the laundry and a control method thereof. Background technique [0002] figure 1 is a sectional view of a washing machine according to the prior art. [0003] A drum washing machine according to the prior art includes: a housing 102 for forming an appearance; a washing tub disposed in the housing 102 for storing washing water; a drum rotatably disposed in the washing tub 104 for washing and dehydrating clothes 106 ; and a drive motor 110 connected to the drum 106 via a drive shaft 108 for rotating the drum 106 . [0004] The washing tub 104 is supported in the housing 102 in a vibration-absorbing manner through shock absorbers 120 and 122 , and a heater 130 for heating washing water stored in the washing tub 104 is provided at a lower portion of the washing tub 104 .
