<p><P>PROBLEM TO BE SOLVED: To provide a washing and drying machine which has an improved feature in starting up a drying operation with a heat pump by an energy-saving and compact heat storage means. <P>SOLUTION: A washing and drying machine, in which, during a drying process, a heat pump unit is activated to blow into a water tank the air heated by a condenser, the damp air containing the moisture evaporated from laundry in a rotary drum is discharged from the water tank, the discharged air is cooled to be dehumidified by an evaporator, and then the air is heated by the condenser before being circulated again, is provided with a phase-change heat storage means 26 which stores heat by becoming a supersaturated liquid when exposed to the case of a compressor 12, and which releases heat by becoming solid. The heat from the compressor in operation can be transmitted to the phase-change heat storage means and stored there through its phase change from the solid state into the liquefied state. When the drying process thereafter is started, the phase-change heat storage means undergoes a phase change again by receiving a stimulus from a stimulus application means 31 to release the heat stored through its solidification in order to heat the compressor. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
