  • Publication number: 20090255299
    Abstract: The present invention provides a clothe drier, a washing machine and a washing machine with a clothes drying function, which are improved in the effects of cleaning, deodorizing and sterilizing clothes with ozone, and permit easy replacement of an ozone generation element or safe control of the ozone. An ozone generator (40) generates ozone by applying silent discharge to air introduced therein. The ozone is sucked into a drying air duct (15) by rotation of a blower (20) and a drum (3) and mixed in air heated by a heater (21), and the resulting mixture is supplied into the drum (3) through an inlet (17). Thus, the ozone is supplied to clothes to be dried, thereby effectively deodorizing and sterilizing the clothes. Since the ozone generator (40) is disposed away from the drying air duct (15), the ozone generation element can be easily replaced.

  • Publication number: 20090049874
    Abstract: The washing machine (1) of the invention is a washing machine (1) having a drying function. The washing machine (1) has an ozone generator (47) for supplying ozone to a dry air duct (16) and also has an air wash key (77) for instructing the execution of air wash. Operating the air wash key (77) performs the air wash operation as a treatment independent of washing and drying. In the air wash operation, a blower (21) is turned on and the ozone generator (47) is turned on, and air containing ozone is supplied to clothes stored in a drum (3) to sterilize/deodorize the clothes. In this operation, whether to rotate the drum (3) or to perform the air wash operation with the drum (3) stopped can be selected.
