  • Publication number: 20080289209
    Abstract: A housing for modularizing a heat pump system of a clothes dryer and a clothes dryer having the same are disclosed. The heat pump system modularized housing of the clothes collectively modularizes a condenser, a compressor, an evaporator and an expansion valve that constitute the heat pump system of the clothes dryer. Not only does the heat pump system is stably mounted in the clothes dryer but also components of the heat pump system can be effectively protected. In addition, the fastening procedures of each component can be unified to simplify an assembling process of the clothes dryer, and thus, the productivity can be improved. Moreover, a structure of an internal flow path of the clothes dryer can be simplified to thus improve efficiency of the heat pump system.

  • Publication number: 20070214678
    Abstract: Disclosed in a control method of a clothes dryer. The drying method of a clothes dryer, includes: detecting a temperature of the air exhausted from a drum; determining a change in water content of a drying material on the basis of the detected temperature; and controlling a drying operation according to the water content change of the drying material. Accordingly, the air temperature in an exhaust port of a drum is measured, and a water content or a temperature of a drying material can be determined on the basis of data about a gradient of the temperature change.
