Abstract
In the dry clearing machine, a common refrigerator is used for both the solvent cooler and the drying cooler, and the coolant compressed and liquefied in the refrigerator is supplied either one of the heat exchanger of the solvent cooler or that of the drying cooler, depending on the state of a switch. In the heat exchanger selected by the switch, the coolant is supplied and the solvent or the air is cooled when the coolant evaporates. That is, only the cooler selected by the switch works, but the other cooler not selected by the switch does not work. While the laundry is washed, normally, it is not necessary to supply air to the outer tub through the air path, and the drying cooler need not be operated. Thus, in the process of washing, the solvent is adequately cooled because an enough amount of coolant is supplied to the solvent cooler, and the temperature rise of the solvent is prevented.
