Clothes Drier, Washing Machine, and Washing Machine with Clothes Drying Function
First Claim
1. A clothes drier comprising:
- a treatment tub in which clothes are dried;
a drying air duct having opposite ends and configured to feed air supplied from one of the opposite ends into the treatment tub, the other end being connected to the treatment tub;
an air blowing unit provided in the drying air duct and configured to generate an air stream for feeding the air supplied from the one end into the treatment tub through the other end;
a heating unit provided in the drying air duct for heating air flowing through the drying air duct; and
an ozone generator disposed outside the drying air duct for generating ozone from air sucked from an inlet thereof and releasing the ozone from an outlet thereof, the outlet being connected to a portion of the drying air duct upstream of the air blowing unit with respect to an air flowing direction.

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. After completion of drying, no ozone is present in the drum (3) due to an oxidation reaction, so that the user is unlikely to be influenced by the ozone when taking the clothes out of the drum (3).
