  • Clothes drier
    Patent number: 7194823
    Abstract: A clothes drying apparatus includes a heat pump mechanism, an air path for guiding drying air into a drying drum accommodating therein clothes, a blower for supplying drying air to the air path, and a controller for controlling a driving of a compressor, wherein the controller operates the blower and the compressor during a drying operation; stops the compressor in case the drying operation is suspended; and operates, in case the drying operation is resumed, the compressor after a certain time period has elapsed since the compressor had stopped. In case employing the heat pump mechanism having the compressor as a heat source, it is possible to reduce a load on the compressor and allow temperature of warm air to rapidly return by using the heat pump mechanism.
