When two preset values, if the fall off rate of the temperature of interior bucket is very fast only from the viewpoint of temperature change, thus it is still to persistently add
Heat guarantees drying efficiency to slow down the fall off rate of the temperature of interior bucket；But since the absolute value of the temperature change value of interior bucket is small
In being equal to the first preset value, from the perspective of combination temperature variation is with energy consumption, remain current with current consumed electric energy
Temperature fall off rate be not cost-effective enough, thus the heating power of heating device can be further reduced to the 4th default heating
Power, to further decrease the consumption of electric energy.And if the absolute value of the temperature change value of interior bucket is less than or equal to the second preset value,
Then the temperature-visualized of interior bucket is to be basically unchanged, this shows that there is no the vapor of heat exchange substantially in interior bucket, thus controllable
Heater stop work.
It should be noted that first to fourth above-mentioned default heating power, the first preset temperature, the first preset value and
Two preset values etc. can be set according to conditions such as the parameter of heating device, the heat resistances of the capacity of washing machine and clothing.
The drying control method of washing machine according to an embodiment of the present invention passes through the temperature of the interior bucket of real-time detection washing machine
Degree, and according to the temperature variations of the temperature of interior bucket acquisition interior bucket, then according to the temperature change of the temperature of interior bucket and interior bucket
The heating power of heating device is adjusted in situation, is convenient for being adjusted according to demand for heat actual in drying course as a result,
The heating power of heating device avoids heating power so that the heating power of heating device matches with actual demand for heat
