Title:
WASHING AND DRYING MACHINE
Document Type and Number:
WIPO Patent Application WO/2014/016879
Kind Code:
A1
Abstract:
This washing and drying machine comprises: a water tank (340); a rotary drum (330); a first water-drainage pathway; a water-drainage valve (620); a heat exchanger (420); a water-sprinkling mechanism that cleans the heat exchanger (420); a second water-drainage pathway; and a control unit. In a water-drainage starting step, in which the water-drainage valve (620) is opened, and a water-drainage ending step, in which the water-drainage valve (620) is closed, at the time of draining water in a washing step and/or a rinsing step, the control unit executes control such that the sprinkling of water from the water-sprinkling mechanism is ended at least before the water-drainage ending step. Thus, the water-drainage pathways are prevented from getting clogged with foreign matters included in cleaning water that cleaned the heat exchanger (420).
