Clothes treating apparatus and control method thereof

A clothes treating apparatus comprising:

• a first cabinet that defines at least a portion of an outer appearance of the clothes treating apparatus;
• a first drum rotatably disposed in the first cabinet and configured to accommodate clothes;
• a circulation duct configured to guide air discharged from the first drum;
• a heat exchange part disposed inside the circulation duct, the heat exchange part comprising a first heat exchanger and a second heat exchanger that are configured to perform heat exchange with the air in the circulation duct;
• a filter disposed inside the circulation duct and configured to separate foreign substances from the air in the circulation duct prior to the heat exchange;
• a second cabinet disposed below the first cabinet;
• a tub disposed inside the second cabinet and configured to receive water;
• a second drum rotatably disposed inside the tub and configured to accommodate clothes;
• an injector configured to spray water to the first heat exchanger or the filter;
• a water supply connected to an external water supply source and configured to supply water to the tub or the injector;
• a condensed water storage configured to store condensed water condensed through the heat exchange by the first heat exchanger and configured to store water sprayed through the injector;
• and
• a drainage configured to discharge water from the tub and the condensed water storage to an outside of the clothes treating apparatus,
• wherein the drainage comprises:
• a drain pump configured to cause the water to be discharged from the tub to the outside,
• a first drain pipe that connects the tub to the drain pump,
• a second drain pipe configured to drain the water from the drain pump to the outside,
• a third drain pipe that connects the condensed water storage to the first drain pipe or the drain pump, and
• a drain valve configured to open and close the third drain pipe, and
• wherein the condensed water storage is configured to fluidly communicate with the drainage and to discharge the stored condensed water to the drainage.

A method for controlling a clothes treating apparatus, the clothes treating apparatus including a first cabinet that defines at least a portion of an outer appearance of the clothes treating apparatus, a first drum rotatably disposed in the first cabinet and configured to accommodate clothes, a circulation duct configured to guide air discharged from the first drum, a heat exchange part that is disposed inside the circulation duct and includes a first heat exchanger and a second heat exchanger that are configured to perform heat exchange with the air in the circulation duct, a filter arranged inside the circulation duct and configured to separate foreign substances from the air in the circulation duct prior to the heat exchange, a second cabinet disposed below the first cabinet, a tub disposed inside the second cabinet and configured to receive water, a second drum rotatably disposed inside the tub and configured to accommodate clothes, a condensed water storage configured to store at least one of condensed water that is condensed through the heat exchange by the first heat exchanger, water that is supplied from an external water supply source, or water that is sprayed to the first heat exchanger or the filter, a water supply valve connected to the external water supply source and configured to supply water to the tub or the condensed water storage, an injector configured to spray the water from the condensed water storage to the first heat exchanger or the filter, a dryness sensor disposed at the first drum and configured to measure a dryness of the clothes in the first drum, a water level sensor configured to measure a water level in the condensed water storage, and a drainage including a drain pump configured to cause the water to be discharged from the tub to the outside, a first drain pipe that connects the tub to the drain pump, a second drain pipe configured to drain the water from the drain pump to the outside, a third drain pipe that connects the condensed water storage to the first drain pipe or the drain pump, and a drain valve configured to open and close the third drain pipe, wherein the condensed water storage is configured to fluidly communicate with the drainage and to discharge stored condensed water to the drainage, the method comprising:

• performing a drying operation that includes rotating the first drum;
• comparing the dryness measured by the dryness sensor to a reference dryness;
• based on the measured dryness being greater than or equal to the reference dryness, measuring the water level through the water level sensor;
• based on the water level being lower than a first reference water level, supplying water to the condensed water storage by opening the water supply valve until the water level measured by the water level sensor becomes higher than or equal to the first reference water level;
• and
• cleaning the first heat exchanger or the filter by spraying water through the injector.
