Abstract
A heating device of a clothes drying treatment device executes an on or off operation in a temperature interval. When the temperature in a drum reaches an upper limit value TDx of the temperature interval under an action of the heating device, the heating device is turned off and the heating device stops heating. The upper limit value TDx decreases as a number of off times x of the heating device increases. Accordingly, a higher initial off temperature is adopted for the heating device, the temperature in the drum rapidly increases to the drying temperature, a preheating time is shortened, and a certain coefficient is multiplied in following control parameters controlling on or off of the heating device. The coefficient is related to the number of on-off times, and the effect is achieved that the off temperature of the clothes dryer gradually decreases as the number of on-off times increases.
