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.
Claims18
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, wherein the recirculating air flow system comprises one or more flow control devices operable to control the flow of process air through the 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,
- wherein selectively energizing the fan during the second portion of the drying cycle includes deenergizing the fan for a time period.
