A controlling method for a dryer is applied to a dryer, in which at least one of a heat pump system and a heater is selected as a heat source for heating air supplied in to a drum and a heat supply capacity of the heat pump system is more than that of the heater. The controlling method includes, when both the heat pump system and the heater are selected as the heat sources, turning the heat pump system on, turning the heater on after the heat pump system is normally turned on, turning the heater off to cool the drum and terminate drying after the drying is performed, and turning the heat pump system off after the heater is turned off.

Controlling method for clothes dryer

A clothes dryer is provided. The clothes dryer may include a main body having a drum rotatably installed therein, a circulation channel formed in the main body, the circulation channel defining a path of air that flows through the drum to dry an object to be dried, and a heat pump system having an evaporator, a compressor, an expansion apparatus, and a condenser, the heat pump system cooling and heating air that flows through the circulation channel. The evaporator may be mounted in the circulation channel, and a 'U' trap may be positioned below the evaporator in the circulation channel.

Clothes dryer

A laundry machine having a heat exchanger cleaning device may include a cabinet, a drum provided in the cabinet, a heat exchanger for heating air to dry laundry in the drum, air conduits to circulate the air between the heat exchanger and the drum, and a control valve that controls a flow of water to the heat exchanger to clean lint deposits on the heat exchanger. An area of the heat exchanger may be divided into a plurality of regions, such that a first nozzle is coupled to the first outlet port and provided above a first region of the plurality of regions and a second nozzle is coupled to the second outlet port and provided above a second region of the plurality of regions. The control valve may selectively direct the flow of water toward the first nozzle or the second nozzle to clean a desired region.
