[0067] The first embodiment of the present invention applies a method in which when the operation time of the second heater 33 reaches a reference time during generating steam and supplying steam to the washing tub 11, the second heater 33 is turned off to naturally cool the steam generation device 30. Therefore, it is possible to prevent a small amount of scale from accumulating in the steam generating passage 32 .

[0068] When the reference temperature Tr to be compared with the temperature of the body 31 is set to a lower value in the first embodiment, the cooling effect is improved but the cooling time is increased. Therefore, preferably, the reference temperature Tr is set according to the above-mentioned relationship.

[0069] Further, according to the second embodiment of the present invention, in addition to turning off the second heater 33 , the second water supply valve 25 is opened to supply cold water to the steam generating channel 32 . Here, the supplied cold ...

Abstract

A washing machine having a steam generator, which prevents the accumulation of scale in the steam generator due to the long-term use thereof, and a method for controlling the same. The washing machineincludes a water supply valve for supplying water to the inside of the steam generator therethrough so as to cool the steam generator when the operating time of the steam generator exceeds a predetermined time, and a controller for controlling the operation of a heater for heating the water supplied through the water supply valve.

Description

technical field [0001] The present invention relates to a washing machine having a steam generator capable of preventing scale accumulation in the steam generator due to long-term use, and a method for controlling the washing machine. Background technique [0002] Korean Patent Publication No. 2004-0085507 (dated Oct. 8, 2004) discloses a conventional washing machine in which steam is supplied into a tub to increase washing capacity. [0003] The steam generator of the washing machine disclosed in the above patent includes: a pressure vessel having an inlet into which wash water is supplied and an outlet from which steam is discharged; inside the vessel to heat wash water supplied to the pressure vessel; an inlet valve for controlling the supply of wash water into the pressure vessel; and an outlet valve for controlling the discharge of steam from the pressure vessel. [0004] The steam generator further includes: a water level sensor for detecting an amount of washing wate...
