Abstract:
1. 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.
