That is, T _on = -1.2 × T ₁ +122.

Preferably, if the ambient temperature T _{1 is} greater than 25 ° C and less than or equal to 35 ° C (third preset temperature threshold), the first correction coefficient a corresponding to the opening temperature _Ton is -2, and the second correction coefficient b is 142. That is, T _on = -2 × T ₁ + 142.

Preferably, if the ambient temperature T _{1 is} greater than 35 ° C, the first correction coefficient a corresponding to the opening temperature _Ton is 0, and the second correction coefficient b is 72, that is, T _on = 72 ° C.

Certainly, the value of the first correction coefficient and the value of the second correction coefficient are not limited to the values of the foregoing examples, and those skilled in the art can flexibly adjust in actual operation as long as the ambient temperature is less than or equal to the first preset. When the temperature threshold is reached, the turn-on temperature T _on remains unchanged. When the ambient temperature is less than or equal to the second preset temperature threshold, the turn-on temperature T _on is inversely proportional to the ambient temperature T ₁ when the ambient temperature is less than or equal to the third preset temperature. When the threshold value is reached, the opening temperature T _on is inversely proportional to the ambient temperature T ₁ . When the ambient temperature is greater than the third preset temperature threshold, the opening temperature T _on remains unchanged.

The water temperature T _{2 is} high, which affects the accuracy of the temperature sensor detection. If it is not possible to accurately determine whether the heating module needs to be turned on, the opening temperature T _{on is} set to be inversely proportional to the ambient temperature T ₁ and the cooling water temperature T ₂ . So that the opening temperature T _on decreases with the increase of the ambient temperature T ₁ and the cooling water temperature T ₂ to lower the opening temperature of the heating module, avoiding that the laundry has not been dried and the drying process cannot be started or has ended prematurely. The situation occurs, which improves the drying effect of the washing and drying machine, thereby improving the user experience.

Preferably, in the above step S226, if the ambient temperature T _{1 is} greater than the first preset ambient temperature threshold and less than or equal to the second preset ambient temperature threshold, the ambient temperature is higher, regardless of whether the temperature of the cooling water is higher or lower. Both of them affect the accuracy of the temperature sensor detection, and cannot accurately determine whether the heating module needs to be turned on. The turn-on temperature T _{on is} set to be inversely proportional to the ambient temperature T ₁ and the cooling water temperature T ₂ , so that the turn-on temperature T _on The ambient temperature T ₁ and the cooling water temperature T ₂ are lowered to reduce the opening temperature of the heating module, thereby avoiding the fact that the laundry has not been dried and the drying process cannot be started or has ended prematurely, and the washing is improved. The drying effect of the all-in-one machine further enhances the user experience.

The drying effect of the washing and drying machine improves the user experience.

Preferably, in the above step S230, if the ambient temperature T _{1 is} greater than the second preset ambient temperature threshold and the cooling water temperature T _{2 is} greater than the second preset cooling water temperature threshold, the ambient temperature and the cooling water temperature are both too high, The accuracy of the temperature sensor detection greatly affects whether it is impossible to accurately determine whether the heating module needs to be turned on, and the opening temperature T _{on is} set to remain unchanged, that is, the opening temperature T _on does not vary with the ambient temperature T ₁ and the cooling water temperature. The change of T ₂ changes, avoiding the fact that the laundry has not been dried and the drying process cannot be started or has ended prematurely, which improves the drying effect of the washing and drying machine, thereby improving the user experience.

In the above process, by setting the first preset ambient temperature threshold and the first preset cooling water temperature threshold, the conclusion of how to correct the opening temperature can be further given, so that the washing and drying machine can adopt the optimal in different situations.

The demarcation point can meet the requirements for correcting the opening temperature.

Further, by setting the second preset ambient temperature threshold and the second preset cooling water temperature threshold, the conclusion of how to correct the opening temperature can be further given, so that the washing and drying machine can adopt the optimal correction under different conditions. The mode can accurately judge the opening temperature of the heating module and improve the drying effect of the washing and drying machine. The setting of the second preset ambient temperature threshold and the second preset cooling water temperature threshold may be flexibly adjusted and set according to actual conditions, for example, the second preset ambient temperature threshold is 35 ° C, and the second preset cooling The water temperature threshold is 35 ° C, as long as the boundary point between the first correction coefficient and the second correction coefficient determined by the second preset ambient temperature threshold and the second preset cooling water temperature threshold can meet the requirement of correcting the opening temperature. .
