The pump 162 may be operated when the level measured by the sump level detecting unit 161-1 is greater than or equal to the reference sump level.

The steam generator 165 supplies steam to the drum 110. The steam generator 165 receives condensed water collected in the sump 161 and heats it to generate steam, and supplies the generated steam to the drum 110. The steam generator 165 may be replaced with an atomizer that sprays the drum 110 according to an embodiment.

The steam generator 165 includes a steam level detector 165-1 measuring the height of the condensed water contained in the steam generator 165. The steam level detector 165-1 may measure the level of the steam generator 165 using an electrode.

The steam valve 163 guides the condensate collected in the sump 161 to the steam generator 165 or the fixed condensate tank 168. The steam valve 163 is a three-way valve to allow condensate pumped by the pump 162 to be directed to the steam generator 165 or the fixed condensate tank 168.

A steam filter 164 may be provided between the steam valve 163 and the steam generator 165. The steam filter 164 filters condensate flowing from the steam valve 163 to the steam generator 165 to filter foreign matter.

When the water level measured by the steam level detector 165-1 is equal to or less than the reference steam level, the steam valve 163 guides the condensed water collected in the sump 161 to the steam generator 165. However, when the water level measured by the steam level detector 165-1 is greater than or equal to the reference steam level, the steam valve 163 guides the condensate collected in the sump 161 to the fixed condensate tank 168.

A tank valve 167 is provided between the fixed condensate tank 168 and the drawer condensate tank 169. The tank valve 167 prevents condensate contained in the fixed condensate tank 168 when the drawer condensate tank 169 is drawn out of the drawer condensate tank 169. The tank valve 167 is provided in the drawer type condensate tank 169 and is opened when the drawer type condensate tank 169 is mounted in the cabinet 101 and is closed when the drawer type condensate tank 169 is withdrawn.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, It should be understood that various modifications may be made by those skilled in the art without departing from the spirit and scope of the present invention.
