Specifically, in the above step S222, if the ambient temperature T _{1 is} less than or equal to the first preset temperature threshold, it indicates that the ambient temperature is low, and does not affect the shutdown temperature of the drying mode, and can accurately determine whether it is necessary to bake. When the dry mode is off, the shutdown temperature _{Toff is} set to remain unchanged, that is, the shutdown temperature _Toff does not change with changes in ambient temperature.

Preferably, in the above step S224, if the ambient temperature T _{1 is} greater than the first preset temperature threshold and less than or equal to the second preset temperature threshold, the ambient temperature is high, which may affect the shutdown temperature of the drying mode, and may not be accurate. Determining whether the drying mode needs to be turned off, the closing temperature T _{off is} set to be proportional to the ambient temperature T ₁ such that the closing temperature T _off increases as the ambient temperature increases to increase the closing temperature of the drying mode. It avoids the situation that the clothes have not been dried and the drying mode has ended prematurely, 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 second preset temperature threshold, indicating that the ambient temperature is high, the shutdown temperature of the drying mode is greatly affected, and the drying mode cannot be accurately determined. When it is turned off, the shutdown temperature T _{off is} set to remain unchanged, that is, the shutdown temperature T _off does not change with the change of the ambient temperature, thereby avoiding the situation that the laundry has not been dried and the drying mode has ended prematurely, thereby improving The drying effect of the washing and drying machine improves the user experience.

In the above process, by setting the first preset temperature threshold, the conclusion of how to correct the shutdown temperature can be further given, so that the washing and drying machine can adopt the optimal correction mode under different conditions, and can accurately judge the drying mode. The closing temperature improves the drying effect of the washing and drying machine. The first preset temperature threshold may be the lowest temperature of the ambient temperature, for example, the first preset temperature threshold is 10 ° C, and the correction scheme of the shutdown temperature is optimal to improve the drying effect of the washing and drying machine. Of course, the first preset temperature threshold is not limited to the lowest temperature of the ambient temperature, and may be other temperatures, such as experimental temperatures obtained by a person skilled in the art according to experiments under specific working conditions, or empirical temperatures derived from experience. As long as the boundary point between the first correction coefficient and the second correction coefficient determined by the first preset temperature threshold is satisfied, the requirement for correcting the shutdown temperature can be satisfied.

Further, by setting the second preset temperature threshold, the conclusion of how to correct the shutdown temperature can be further given, so that the washing and drying machine can adopt the optimal correction mode under different conditions, and can accurately determine the drying mode. The temperature is turned off, which improves the drying effect of the washing and drying machine. The setting of the second preset temperature threshold may be flexibly adjusted and set according to actual conditions, for example, the second preset temperature threshold is 35 ° C, as long as the first correction coefficient determined by the second preset temperature threshold is met. The boundary point of the second correction coefficient can satisfy the requirement of correcting the shutdown temperature.

Preferably, if the ambient temperature T _{1 is} less than or equal to 10 ° C (the first preset temperature threshold), the first correction coefficient a corresponding to the shutdown temperature T _off is 0, and the second correction coefficient b is 70, that is, T _off = 70 ° C.

Preferably, if the ambient temperature T _{1 is} greater than 10 ° C and less than or equal to 35 ° C (second preset temperature threshold), the first correction coefficient a corresponding to the shutdown temperature T _off is 1 and the second correction coefficient b is 55. That is, T _off = T ₁ +55.

Preferably, if the ambient temperature T _{1 is} greater than 35 ° C, the first correction coefficient a corresponding to the shutdown temperature T _off is 0, and the second correction coefficient b is 80, that is, T _off = 80 ° 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 T _off shutdown temperature remains constant when the ambient temperature is greater than a first predetermined temperature threshold and less than or equal to a second predetermined temperature threshold T _off and the shutdown temperature ambient temperature T ₁ was a positive relationship, when the ambient temperature When the threshold value is greater than the second preset temperature, the requirement that the temperature _{Toff is} kept unchanged may be used.

In the above step S3, the step of "selectively turning off the drying mode according to the corrected shutdown temperature" specifically includes:

S31, detecting the temperature of the outer cylinder;

S32. Compare the detected temperature of the outer cylinder with the corrected shutdown temperature;

S33. Determine whether the temperature of the outer cylinder is greater than or equal to the closed temperature after the correction;

S34, if yes, controlling the washing and drying machine to turn off the drying mode;

S35. If not, control the washing and drying machine to maintain the drying mode.

Specifically, in the above step S34, if the temperature of the outer cylinder is greater than or equal to the closed temperature after the correction, indicating that the temperature of the outer cylinder is already high, and the temperature of the closed drying mode is reached, the washing and drying machine is controlled to turn off the drying mode.

Preferably, in the above step S35, if the temperature of the outer cylinder is less than the corrected closing temperature, the temperature of the outer cylinder is already low, and the temperature of the drying mode has not been reached, and the drying mode can be continued, then the washing and drying machine is controlled.
