Abstract
A clothes dryer and method for forming and supplying a treating chemistry solution to a laundry load located in the treating chamber of the clothes dryer.
Claims23
A method of operating a clothes dryer having a rotating treating chamber into which heated air may be provided to dry a wet laundry load within the treating chamber, the method comprising:
- automatically determining a size of the laundry load within the treating chamber;
- automatically determining an amount of treating chemistry to be applied to the laundry load based on the determined size of the laundry load;
- automatically determining an application concentration at which the amount of treating chemistry is to be applied to the laundry load based on the determined size of the laundry load;
- forming a treating solution by mixing a concentrated form of the amount of treating chemistry with a diluent such that the treating solution has an application concentration of the treating chemistry;
- and
- supplying the treating solution to the treating chamber,
- wherein the automatically determining the size of the laundry load comprises automatically determining a qualitative size of the laundry load, and wherein the qualitative size is based on a quantitative size of the laundry load.
4 more elements
A clothes dryer configured to treat a load of laundry according to a cycle of operation, comprising:
- a rotatable treating chamber configured to receive the load of laundry;
- an air system for supplying air to the treating chamber;
- a heating system for heating the supplied air;
- a dispensing system configured to form a treating solution from a mixture of treating chemistry and diluent and dispense the treating solution to the treating chamber;
- a load size sensing system configured to sense a size of the load located in the treating chamber and provide an output indicative thereof;
- and a controller operably coupled with the load size sensing system to receive the output, and configured to determine a qualitative size of the laundry load based on the output, to control the operation of the dispensing system, to determine an amount of treating chemistry to be dispensed based on the qualitative size, and to control a concentration of the treating chemistry in the treating solution based on the qualitative size.
