Abstract

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.
