The present invention provides a dry-cleaning machine capable of performing a water-repellent finishing process when necessary, while ensuring a high level of safety. When the water-repellent finishing process has been performed after the drying process (Step S), the solvent contained in the water repellent penetrates into the laundry articles. Taking this into account, the upper limit for the temperature difference ?T between the inlet and outlet of the drum detected is set lower (e.g. 10&#xb0; C.) than that the upper limit (e.g. 20&#xb0; C.) applied to the case where no water-repellent finishing process is performed. This temperature setting reduces the amount of heat supplied to the laundry articles and accordingly decreases the evaporating speed of the solvent. Thus, the concentration of the gasified solvent in the air-circulating passage is maintained under the safety level. In this case, the time period for the drying operation is set longer to compensate for the deterioration in the drying efficiency.

Dry-cleaning machine

There are disclosed a heat pump device and a drying machine using the device in which abnormal water supplying into a water-cooling heat exchanger for use in water-cooling of a heat pump can be easily detected without disposing any water amount gauge particularly. The heat pump device comprises: a water-cooling heat exchangerfor taking heat of a refrigerant which enters a capillary tubea water amount adjusting valvefor adjusting the amount of cooling water to be supplied to the water-cooling heat exchangera temperature sensororfor detecting temperature of the cooling water in the water-cooling heat exchangeror temperature of the refrigerant passed through the water-cooling heat exchanger; and a control unitfor controlling the water amount adjusting valveand the control unit judges abnormal water supplying into the water-cooling heat exchangerin accordance with the controlling state of the water amount adjusting valveand a change of the temperature detected by the temperature sensor under the controlling state.

Heat pump device and drying machine

An object is to provide a drying machine which can accomplish delicate drying and reduce burdens on a matter to be dried during drying while securing a predetermined evaporation temperature in an evaporator. In summary, a dry cleaner equipped with a heat pump device comprises a water-cooling heat exchanger which removes heat from a refrigerant entering a capillary tube; and a control device which variably controls a discharged heat amount in the water-cooling heat exchanger and capacity of the compressor, wherein the control device has at least two kinds of drying modes including a usual drying mode and a delicate drying mode, and in the delicate drying mode, a temperature of air discharged into a storage chamber is set lower than in the usual drying mode to control the capacity of the compressor and to increase the discharged heat amount in the water-cooling heat exchanger.
