Abstract

A method of operating a laundry treatment appliance including a chamber for receiving a laundry load and a water supply provided within the chamber includes determining a target moisture level of the laundry load; initiating a drying cycle of the laundry load, the drying cycle including a primary drying time; initiating a spray operation for providing moisture into the chamber; determining that a measured moisture level of the laundry load meets a moisture goal based on the target moisture level; and ceasing the spray operation in response to determining that the measured moisture level meets the moisture goal.

Claims (43)

1 . A method of operating a laundry treatment appliance, the laundry treatment appliance comprising a chamber for receiving a laundry load and a water supply provided within the chamber and a moisture sensor provided within the chamber, the method comprising:

determining a target moisture level of the laundry load;

initiating a drying cycle of the laundry load, the drying cycle comprising a primary drying time;

initiating a spray operation for providing moisture into the chamber;

determining that a measured moisture level of the laundry load meets a moisture goal based on the target moisture level; and

ceasing the spray operation in response to determining that the measured moisture level meets the moisture goal.

2 . The method of claim 1 , wherein the spray operation comprises a plurality of pulse periods, each of the plurality of pulse periods having an ON time followed by an OFF time of a spray of moisture.

3 . The method of claim 1 , wherein the moisture sensor is one of a moisture sensor bar for sensing moisture within the laundry load or a humidity sensor for sensing a relative humidity of air within the chamber.

4 . The method of claim 3 , wherein determining that the measured moisture level of the laundry load meets the moisture goal comprises:

obtaining a sensor voltage measured by the moisture sensor; and

determining that the sensor voltage has reached a target voltage corresponding to the moisture goal.

5 . The method of claim 1 , wherein the moisture goal is determined according to a selected dryness level.

6 . The method of claim 5 , wherein the selected dryness level is a user selected dryness level selected by a user via the laundry treatment appliance.

7 . The method of claim 1 , further comprising:

determining an additional amount of drying time, the additional amount of drying time being added to the primary drying time; and

executing the additional amount of drying time after ceasing the spray operation.

8 . The method of claim 7 , wherein determining the additional amount of drying time comprises:

determining a size of the laundry load; and

analyzing a selected dryness level.

9 . A laundry treatment appliance comprising:

a cabinet;

a drum rotatably mounted within the cabinet, the drum defining a chamber to selectively receive a laundry load;

a moisture sensor provided within the chamber to sense a moisture level of the laundry load;

a moisture supply in fluid communication with the chamber to selectively providing moisture into the chamber; and

a controller operably connected with the moisture sensor and the moisture supply, the controller being configured for:

determining a target moisture level of the laundry load;

initiating a drying cycle of the laundry load, the drying cycle comprising a primary drying time;

initiating a spray operation for providing moisture into the chamber;

determining that a measured moisture level of the laundry load meets a moisture goal based on the target moisture level; and

ceasing the spray operation in response to determining that the measured moisture level meets the moisture goal.

10 . The laundry treatment appliance of claim 9 , wherein the spray operation comprises a plurality of pulse periods, each of the plurality of pulse periods having an ON time followed by an OFF time of a spray of moisture.

11 . The laundry treatment appliance of claim 9 , wherein the moisture sensor is one of a moisture sensor bar for sensing moisture within the laundry load or a humidity sensor for sensing a relative humidity of air within the chamber.

12 . The laundry treatment appliance of claim 11 , wherein determining that the measured moisture level of the laundry load meets the moisture goal comprises:

obtaining a sensor voltage measured by the moisture sensor; and

determining that the sensor voltage has reached a target voltage corresponding to the moisture goal.

13 . The laundry treatment appliance of claim 9 , wherein the moisture goal is determined according to a selected dryness level.

14 . The laundry treatment appliance of claim 13 , wherein the selected dryness level is a user selected dryness level selected by a user via the laundry treatment appliance.

15 . The laundry treatment appliance of claim 9 , wherein the controller is further configured for:

determining an additional amount of drying time, the additional amount of drying time being added to the primary drying time; and

executing the additional amount of drying time after ceasing the spray operation.

16 . The laundry treatment appliance of claim 15 , wherein determining the additional amount of drying time comprises:

determining a size of the laundry load; and

analyzing a selected dryness level.
