Abstract

A method of operating a laundry treating appliance with a treating chamber for treating a load of laundry the method comprising supplying a rinse to the treating chamber during a rinse cycle, rotating the treating chamber at a tumbling speed, spinning the treating chamber in an extraction cycle to remove excess moisture from the load of laundry, sensing a parameter indicative of a remaining moisture content value in the load of laundry, comparing the remaining moisture content value to a pre-determined remaining moisture content value.

First claim

What is claimed is:

1. A method of extracting liquid from a laundry load residing in a rotating drum of a laundry treating appliance during a rinsing phase of operation, the method comprising:
a) supplying water into the drum;
b) heating the water in the drum to a predetermined temperature to form hot water;
c) rotating the drum at a tumbling speed;
d) after rotating at the tumbling speed, rotating the drum at a spinning speed;
e) sensing a parameter indicative of a residual moisture content of the laundry load; and
f) comparing the parameter indicative of the residual moisture content of the laundry to a pre-determined residual moisture content value;
g) repeating at least b), c) d), e) and f) until the parameter that is sensed indicates a residual moisture content value below the predetermined residual moisture content value.

2. The method of claim 1 wherein the supplying the water comprises at least one of spraying the water into the drum or immersing at least a portion of the drum in the supplied water.

3. The method of claim 1 wherein the supplying the water further comprises recirculating the water through the drum.

4. The method of claim 1 wherein the heating the supplied water comprises increasing the predetermined temperature for at least one of the repeating of b).

5. The method of claim 1 wherein the spinning speed is increased for at least one of the repeating of d).

6. The method of claim 1 wherein the repeating includes repeating a).

7. The method of claim 1 wherein e) occurs concurrently with d).

8. The method of claim 1 wherein a) occurs concurrently with b).

9. The method of claim 1 further comprising draining the hot water from the drum after the rotating at a spinning speed.

10. The method of claim 1 wherein the sensing a parameter comprises sensing a parameter indicative of a mass of the laundry in the drum.

11. The method of claim 1 wherein the sensing a parameter comprises sensing a conductivity of the laundry load.

12. A method of operating a laundry treating appliance with a treating chamber for treating a load of laundry the method comprising:
heating a water supply to a predetermined temperature to form a hot water rinse;
supplying the hot water rinse to the treating chamber during a hot rinse cycle;
rotating the treating chamber at a tumbling speed;
spinning the treating chamber in an extraction cycle to remove excess moisture from the load of laundry;
sensing a parameter indicative of a remaining moisture content value in the load of laundry;
comparing the remaining moisture content value to a pre-determined remaining moisture content value; and
repeating the hot rinse cycle and the extraction cycle until the remaining moisture content value is less than the pre-determined remaining moisture content value.

13. The method of claim 12 further comprising introducing drying air to the load of laundry during a drying phase after the remaining moisture content value is less than or equal to the pre-determined remaining moisture content value.

14. The method of claim 13 further comprising washing the load of laundry during a wash phase.

15. The method of claim 14 wherein the hot rinse cycle and the extraction cycle define an intermediate phase between the wash phase and the drying phase.

16. The method of claim 15 wherein the wash phase includes washing the load of laundry in a main wash cycle, rinsing the load of laundry in a rinse cycle, and spinning the load of laundry in a first extraction cycle.

17. The method of claim 13 wherein heating the water supply comprises increasing the predetermined temperature if the remaining moisture content value is greater than the pre-determined remaining moisture content value.

18. The method of claim 13 wherein spinning the treating chamber comprises increasing a spinning speed if the remaining moisture content value is greater than the pre-determined remaining moisture content value.

19. The method of claim 13 wherein the sensing a parameter comprises sensing a parameter indicative of a mass of the laundry in the drum.

20. The method of claim 13 wherein the sensing a parameter comprises sensing a conductivity of the laundry load.
