Abstract
A combination washer/dryer having a cabinet defining an interior, a tub provided within the interior, and a drum rotatably provided within the tub and defining a treating chamber, an induction coil carried by the tub and generating a magnetic field encompassing at least a portion of the container, and a cooling element providing on at least one of the tub or closure to form a cooled surface in fluid communication with the treating chamber.
Claims19
A combination clothes washer and dryer comprising:
- a tub defining a tub interior, the tub having a peripheral wall and a sump;
- a rotatable container made from electromagnetic material and located within the tub interior, at least a portion of the rotatable container being made and at least partially defining a laundry treating chamber with an access opening;
- a closure selectively closing the access opening;
- a motor operably coupled to and rotatably driving the rotatable container;
- an induction coil carried by the tub and generating a magnetic field encompassing at least a portion of the rotatable container;
- and
- a cooling element provided on the closure to form a cooled surface in fluid communication with the laundry treating chamber;
- whereby energization of the induction coil heats the container to evaporate liquid in the laundry treating chamber into vapor, which contacts the cooled surface, where the vapor is condensed and is delivered to the sump.
