The sump 161 may be provided with a sump level sensor 161-1 for measuring the height of the condensed water collected in the sump 161. [ The sump level detecting unit 161-1 comprises a buoy and a strain gauge, and the level of the buoy is measured by the strain gauge measuring the level of the buoy according to the level.

The condensate remaining in the sump 161 is pumped by the pump 162. The pump 162 pumps the condensed water collected in the sump 161 to the fixed condensate tank 168. It is preferable that the pump 162 operates when the water level measured by the sump water level sensing unit 161-1 is equal to or higher than the reference sump water level.

The steam generator 165 supplies steam to the drum 110. The steam generator 165 supplies condensed water collected in the sump 161 to heat the steam to generate steam, and supplies the generated steam to the drum 110. The steam generator 165 may be replaced by a sprayer that is sprayed onto the drum 110 in accordance with an embodiment.

The steam generator 165 includes a steam level sensing unit 165-1 for measuring the height of the condensed water received in the steam generator 165. The steam level detector 165-1 preferably measures the level of the steam generator 165 using an electrode.

The steam valve 163 guides the condensed water 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 that allows the condensate pumped by the pump 162 to be directed to the steam generator 165 or 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 the condensed water flowing from the steam valve 163 to the steam generator 165 to filter the foreign substances.

When the water level measured by the steam level sensor 165-1 is lower 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 sensing unit 165-1 is equal to or higher than the reference steam level, the steam valve 163 guides the condensed water 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 type condensate tank 169 described above. The tank valve 167 prevents condensate contained in the fixed condensate tank 168 from flowing out to the drawer type condensate tank 169 when the drawer type condensate tank 169 is drawn out. The tank valve 167 is provided in the drawer type condensate tank 169 to open when the drawer type condensate tank 169 is mounted to the cabinet 101 and to close when the drawer type condensate tank 169 is drawn out.

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.
