Laundry treating appliance with induction heat
A laundry treating appliance comprising 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, and a method of operation which includes a washing cycle, a spinning cycle and a drying cycle.
1. A laundry treating appliance comprising:
a tub defining a tub interior with a sump;
a rotatable container located within the tub interior 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; and
a condenser system comprising:
a water supply assembly;
an induction heater comprising an induction coil carried by the tub and an electromagnetic element carried by the rotatable container, and
a header comprising multiple spray nozzles in fluid communication with the water supply assembly and extending axially along an interior wall of the tub defining a cooled surface on the interior wall of the drum which is in fluid communication with the treating chamber and the sump;
whereby energization of the induction coil heats the electromagnetic element to evaporate liquid in the treating chamber into vapor, which contacts the cooled surface, where the vapor is condensed and is delivered to the sump.
2. The laundry treating appliance of claim 1 wherein the cooled surface is located exteriorly of the treating chamber.
3. The laundry treating appliance of claim 2 wherein the cooled surface is provided on the tub.
4. The laundry treating appliance of claim 3 wherein the tub comprises a peripheral wall and the cooled surface comprises a portion of the peripheral wall.
5. The laundry treating appliance of claim 1 wherein the cooled surface is provided on the closure.
6. The laundry treating appliance of claim 1 wherein the cooled surface further comprises a water curtain.
7. The laundry treating appliance of claim 6 wherein the water curtain is fluidly coupled to the sump.
8. The laundry treating appliance of claim 1 wherein the cooled surface comprises an air curtain.
9. The laundry treating appliance of claim 8 wherein the air curtain comprises ambient air flowed over a portion of the tub or closure.
10. The laundry treating appliance of claim 1 wherein the cooled surface comprises a cooling element in contact with a portion of the tub or closure.
11. The laundry treating appliance of claim 10 wherein the cooling element comprises an evaporator.
12. The laundry treating appliance of claim 1 wherein at least a portion of the container is made from electromagnetic material to form the electromagnetic element.
13. The laundry treating appliance of claim 12 wherein the entire container is made from the electromagnetic material.
14. The laundry treating appliance of claim 1 comprising at least one of a clothes dryer or a combination clothes washer and dryer.
15. The laundry treating appliance of claim 1 wherein the container comprises at least one of a perforated basket configured to rotate about a vertical axis or a perforated drum configured to rotate about a horizontal axis.
16. The laundry treating appliance of claim 1 wherein the cooled surface extends axially across a width of the tub.
17. The laundry treating appliance of claim 16 wherein the cooled surface extends circumferentially around at least a portion of the tub.
