Furthermore, by setting the second preset environment temperature threshold and the second preset cooling water temperature threshold, the conclusion on how to correct the closing temperature can be further given, so that the washing and drying integrated machine can adopt an optimal correction mode under different conditions, the closing temperature of the heating module can be accurately judged, and the drying effect of the washing and drying integrated machine is improved. The setting of the second preset environment 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 environment temperature threshold is 35 ℃, the second preset cooling water temperature threshold is 35 ℃, as long as the requirement that the boundary point of the selected first correction coefficient and the second correction coefficient determined by the second preset environment temperature threshold and the second preset cooling water temperature threshold can meet the requirement of correcting the closing temperature is met.
It should be further noted that the opening temperature of the heating module may also be corrected by the above method, as long as at least one of the first correction coefficient, the second correction coefficient, the third correction coefficient and the fourth correction coefficient corresponding to the opening temperature is different from at least one of the first correction coefficient, the second correction coefficient, the third correction coefficient and the fourth correction coefficient corresponding to the closing temperature, so that the corrected opening temperature is less than the corrected closing temperature. Of course, the opening temperature of the heater module may be set to a fixed value. The two schemes can be selected according to actual use requirements.
