Abstract
Disclosed is a clothes dryer including a heat exchanger for condensing air discharged from a drum to remove moisture from the air, a collector for collecting condensed water produced in the heat exchanger, a first pump for pumping the condensed water from the collector to a water tank, and a discharge unit for selectively discharging the condensed water from the water tank, to wash the heat exchanger using the condensed water.
Claims10
A dryer, comprising:
- a drum to accommodate an object to be dried;
- a housing provided under the drum, the housing having a top cover and a base;
- a heat exchanger in the housing, and the heat exchanger is configured to condense air from a drum;
- a collector provided under the heat exchanger in the housing, and the collector is configured to collect condensed water from the heat exchanger;
- a first pump to provide the condensed water from the collector to a tank;
- a second pump disposed on the top cover of the housing, and the second pump to provide the condensed water from the tank to the heat exchanger;
- a guide line arranged beneath the second pump and configured to connect the second pump to the collector so as to guide water leaking from the second pump to the collector, the guide line extending through the heat exchanger;
- a discharge line to couple between the water tank and the second pump, and the condensed water to pass through the discharge line;
- a valve at the discharge line between the water tank and the second pump for selectively opening and closing the discharge line;
- and
- a washing member to couple to the second pump via an injection line, the washing member is provided at the top cover of the housing, and the washing member to provide the condensed water to the heat exchanger in the housing.
