Abstract: A clothes treating apparatus having a drying function includes: a cabinet; a drum provided within the cabinet; a heat-exchanger heat-exchanged with air exhausted from the drum; a lint filter disposed on an upstream side of the heat-exchanger with respect to flow of air exhausted from the drum to collect lint in the air; a spray tube spraying water to the lint filter to separate lint collected in the lint filter from the lint filter; and a lint collecting part at least partially provided below the lint filter or below the heat-exchanger to collect falling lint. Lint in condensate water may be collected, and thus, generation of a bad influence when condensate water is re-used may be suppressed. Also, contact between lint in drying air and the heat-exchanger may be restrained.

Abstract: A dryer is provided. The dryer may include an expansion valve that may be varied in response to changes in operation mode. The dryer may be a condensation type heat pump dryer, and, in an operation method thereof, the expansion valve may be varied according to an on/off of a solenoid valve corresponding to a selected operation mode. In a first operation mode the heater may be turned on so that heating is supplied by both the heat pump and the heater to provide for rapid drying. In a second operation mode the heater may be turned off to provide for more economical operation. By employing multiple operation modes, a required refrigerant flow rate may be controlled.
