Abstract
A method of operating a laundry appliance includes rotating a laundry basket at a tumble speed during a drying cycle of a laundry appliance and energizing a conditioning system for process air. A fan is operated at a first speed to recirculate a flow of process air for a portion of a drying cycle. The conditioning system is deenergized and the fan is operated at a second speed during a second portion of the drying cycle where the second speed less than the first speed.
Claims20
A laundry appliance comprising:
- a tub positioned within a cabinet;
- a basket supported for rotation within the tub, the basket defining a chamber for receipt of laundry articles for drying;
- a conditioning system comprising a dehumidification section and a heating section;
- a recirculating air flow system for providing fluid communication between the chamber and the conditioning system, wherein the recirculating air flow system, the conditioning system, and the basket define a process air flow path;
- a fan operable to move a flow of process air through the process air flow path;
- and
- a controller operably coupled to the conditioning system and the fan, the controller being configured to:
- rotate the basket at a tumble speed during a drying cycle;
- energize the conditioning system;
- energize the fan to operate at a first speed to recirculate a first air flow through the recirculating air flow system during a first portion of the drying cycle;
- deenergize the conditioning system;
- and
- selectively energize the fan to operate at a second speed during a second portion of the drying cycle, the second speed less than the first speed.
A method of operating a laundry appliance, the laundry appliance comprising a basket supported for rotation within a tub, a conditioning system comprising a dehumidification section and a heating section, a recirculating air flow system in fluid communication with the basket and the conditioning system, wherein the recirculating air flow system, the conditioning system, and the basket define a process air flow path, and a fan operable to move a flow of process air through the process air flow path, the method comprising:
- rotating the basket at a tumble speed during a drying cycle;
- energizing the conditioning system;
- energizing the fan to operate at a first speed to recirculate a first air flow through the recirculating air flow system during a first portion of the drying cycle;
- deenergizing the conditioning system;
- and
- selectively energizing the fan to operate at a second speed during a second portion of the drying cycle, the second speed less than the first speed.
