Abstract
A laundry treating appliance and method of operating a laundry treating appliance that includes wetting the laundry load in a drum according to a selected cycle of operation. A controller associated with the laundry treating appliance may be configured to determine a remaining moisture content of the laundry and a time remaining in the selected cycle of operation based on the remaining moisture content.
Claims20
A method of operating a laundry treating appliance in accordance with an automatic cycle of operation, the laundry treating appliance having a drum at least partially defining a treating chamber and rotatable about an axis of rotation, a motor configured to rotate the drum, a liquid supply system, and a controller configured to implement the cycle of operation, the method comprising:
- receiving, as user input provided to the controller, a selected final remaining moisture content of a laundry load;
- wetting the laundry load with liquid from the liquid supply system according to at least one of a wash phase or a rinse phase of a selected cycle of operation to define a selected phase, the wetted laundry load having a first remaining moisture content;
- during the selected phase, rotating the drum;
- determining, by an imbalance sensor in communication with the controller, a magnitude of imbalance of the laundry load;
- determining, by the controller, a first extraction speed for rotating the drum during an extraction phase to extract moisture from the laundry load based on the magnitude of imbalance;
- during the extraction phase, determining, by the controller, a time remaining in the extraction phase to decrease the first remaining moisture content of the laundry to the selected final remaining moisture content, wherein the controller is configured to provide the selected final remaining moisture content and a value indicative of the first extraction speed as input into a first function that provides an output indicative of the time remaining in the extraction phase;
- and
- rotating the drum at the first extraction speed to extract moisture from the laundry load to decrease the remaining moisture content of the laundry load to the selected final remaining moisture content as determined by a moisture sensor.
A laundry treating appliance, comprising:
- a drum at least partially defining a treating chamber for receiving a laundry load for treatment according to a cycle of operation and rotatable about an axis of rotation;
- a liquid supply system fluidly coupled with the treating chamber for supplying liquid to the laundry load to wet the laundry load to a first remaining moisture content according to at least one of a wash phase or a rinse phase of the cycle of operation to define a selected phase;
- a motor operably coupled with the drum and configured to rotate the drum according to the selected cycle of operation;
- and
- a controller operably coupled with the motor and configured to control the motor to rotate the drum, the controller being further configured to:
- receive, as input from a user, a selected final remaining moisture content of the laundry load;
- determine, by an imbalance sensor, a magnitude of imbalance of the laundry load;
- determine a first extraction speed for rotating the drum during an extraction phase to extract moisture from the laundry load based on the magnitude of imbalance;
- provide the selected final remaining moisture content and a value indicative of the first extraction speed as input into a first function that provides an output indicative of a time remaining in the extraction phase;
- and
- rotate the drum at the first extraction speed to extract moisture from the laundry load to decrease the remaining moisture content of the laundry load to the selected final remaining moisture content as determined by a moisture sensor.
The laundry treating appliance of d 16, further comprising a user interface operably coupled with the controller, the controller configured to control the user interface to display the time remaining in the extraction phase based on output indicative of the time remaining in the extraction phase.
A method of operating a laundry treating appliance in accordance with an automatic cycle of operation, the laundry treating appliance having a drum at least partially defining a treating chamber and rotatable about an axis of rotation, a motor configured to rotate the drum, a liquid supply system, and a controller configured to implement the cycle of operation, the method comprising:
- receiving as user input to the controller, a selected final remaining moisture content of a laundry load;
- wetting the laundry load with liquid from the liquid supply system according to at least one of a wash phase or a rinse phase of a selected cycle of operation to define a selected phase, the wetted laundry load having a first remaining moisture content;
- rotating the drum at an extraction speed to extract at least a portion of the liquid wetting the laundry load;
- determining, by an imbalance sensor, a magnitude of imbalance of the laundry load and a rotation speed for the drum for extracting moisture from the laundry load based upon the magnitude of imbalance;
- determining, by input from a moisture sensor provided to the controller, a remaining moisture content of the laundry;
- determining, by the controller, a time remaining in the selected cycle of operation based on the remaining moisture content of the laundry;
- rotating the drum at the rotation speed to extract moisture from the laundry until a moisture content of the laundry load reaches the selected final remaining moisture content;
- and
- displaying the time remaining on a user interface.
