Patent number: 7367206Abstract: 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 S2), 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° C.) than that the upper limit (e.g. 20° 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.Type: GrantFiled: September 22, 2003Date of Patent: May 6, 2008Assignee: Sanyo Electric Co., Ltd.Inventors: Nobuhiro Asada, Mitsuru Naganawa, Masafumi Nishino

Patent number: 7322123Abstract: 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.Type: GrantFiled: September 7, 2005Date of Patent: January 29, 2008Assignees: Sanyo Electric Co., Ltd., Sanyo Electric Techno Clean Co., Ltd.Inventors: Masaya Tadano, Tetsuya Masuda, Takahiro Nakamura, Masafumi Nishino, Nobuhiro Asada, Mitsuru Naganawa
