DEVICE AND METHOD FOR NON-AQUEOUS WASHING

Japanese Patent JPH1133289

A

PROBLEM TO BE SOLVED: To provide a method and a device for washing with which laundry is washed at home while using safe, effective and non-aqueous washing liquids with low environmental load. SOLUTION: A spinning tub 16 is arranged in a washing machine 11 and the washing liquid is supplied from an operating liquid storage unit 12 to the spinning tub 16. When the operating liquid is charged into the spinning tub 16, a three-way valve 22 is opened between conduits 23 and 24, and the operating liquid enters a compressor/condensor 25 and is partially condensed at least. The combination of laundry and operating liquid is stirred by a stirring means in a comparatively short time in comparison with an automatic washing machine to use water as the operating liquid in the spinning tub 16. After a washing cycle, a three-way valve 27 is opened and conduits 28 and 29 are communicated. An already activated drain pump pumps up the operating liquid through the three-way valve 27 and a conduit 32 and discharges it to a dirty water container 33. The operating liquid is evaporated in the dirty water container 33 and while remaining captured dirty particles in the dirty water container 33, the gaseous operating liquid is returned through a conduit 34, filter 35 and conduit 19 to a tank 17.
