Abstract

The present invention relates to a method for controlling a garment processing device. The garment processing device comprises: a drum into which objects to be dried are introduced; a blower for circulating air in the drum; a heat pump comprising a first heat exchanger and a second heat exchanger so as to dehumidify/heat air; a water collector for collecting condensed water generated in the first heat exchanger; a condensed water pump for discharging condensed water from the water collector; and a channel switching valve for switching a condensed water discharge channel or a channel for washing the first heat exchanger. The method comprises: a first water level sensing step for sensing the level of water in the water collector; a first water discharge step for operating the condensed water pump and simultaneously slowing down the operation of the blower for a predetermined time upon sensing in the first water level sensing step that the level of water in the water collector has reached the top level; a second water level sensing step for sensing the number of times the level of water in the water collector reaches the top level for a present time after the first water discharge step; a channel switching valve initializing step for initializing the channel position of the channel switching valve if the number of times the level of water in the water collector reaches the top level, sensed in the second water level sensing step, reaches a preset number of times; and a second water discharge step for discharging condensed water by operating the condensed water pump for discharging condensed water and simultaneously slowing down or stopping the operation of the blower after the channel switching valve initializing step.
