Abstract
A method for estimating the temperature of a laundry load in a treating chamber of a laundry dryer.
Claims16
A method of estimating a temperature of a laundry load in a treating chamber of a laundry dryer during a drying cycle of operation, with the treating chamber having an air inlet and an air outlet, comprising:
- determining a perturbed air value comprising at least one of a moist enthalpy, an air mass flow rate, a humidity ratio or a temperature indicative of a thermodynamic state of air passing through the treating chamber and contacting the laundry load;
- determining an unperturbed air value indicative of a thermodynamic state of air passing through the treating chamber and contacting the laundry load;
- determining in real-time an estimate of a laundry temperature value indicative of the laundry load temperature based on the perturbed air value and the unperturbed air value during the drying cycle of operation;
- and
- setting at least one parameter of the drying cycle of operation based on the real-time estimate of the laundry temperature value.

A method of estimating a temperature of a laundry load in a treating chamber of a laundry dryer during a drying cycle of operation, with the treating chamber having an air inlet and an air outlet, comprising:
- determining an inflow temperature value indicative of the temperature of air entering the treating chamber;
- determining an outflow temperature value indicative of the temperature of air exiting the treating chamber;
- determining a load size value indicative of the size of the laundry load in the treating chamber;
- determining in real-time an estimate of a laundry temperature output indicative of the laundry load temperature during the drying cycle of operation based on the inflow temperature value, the outflow temperature value, and the load size value during the cycle of operation;
- and
- setting at least one parameter of the cycle of operation based on the real-time estimate of the laundry temperature output.
