Patent number: 6507965Abstract: The present invention teaches a washing machine having improved cleaning efficiency by adding a generator of functional waster such as ozone water or electroylzed water to a full-automatic washing machine. The washing machine includes a water supplier for supplying washing water, a washing tub containing the washing water and a laundry, a functional water generator inside the washing tub, and an agitator for agitating the washing water and the laundry. When the washing water supplied to the washing tub reaches a predetermined level, the functional water generator generates ozone water or electrolyzed water, which is then mixed by the agitator. Thus, partial decolorization or damage of laundry can be prevented. Also, since ozone water or electrolyzed is maintained in the washing tub in a constant concentration, the laundry can be sterilized, disinfected, bleached and deodorized without being heated, which avoids damage to the laundry.Type: GrantFiled: December 13, 2000Date of Patent: January 21, 2003Assignee: EcoAid Corp.Inventor: Dong Heon Kown

Publication number: 20030005523Abstract: A carbon dioxide dry cleaning system features a pair of liquid carbon dioxide storage tanks in communication with a compressor. A sealed cleaning chamber contains the objects to be cleaned. By selectively pressurizing the storage tanks with the compressor, liquid carbon dioxide is made to flow to the cleaning chamber through cleaning nozzles so as to provide agitation of the objects being dry cleaned. Liquid carbon dioxide displaced from the cleaning chamber returns to the storage tanks. In an alternative embodiment, a single storage tank is pressurized via a compressor with gas from the cleaning chamber so that liquid solvent from the storage tank travels to the cleaning chamber through nozzles. The objects in the cleaning chamber are agitated by a rotating basket. After a prewash cycle, liquid solvent from the cleaning chamber is directed to a still. The liquid solvent in the still is boiled through a connection with the head space of the cleaning chamber.Type: ApplicationFiled: August 30, 2002Publication date: January 9, 2003Inventors: A.
