Temperature control method for clothes drying treatment device, and clothes drying treatment device

A temperature control method for a clothes drying treatment device, comprising a heating device of the clothes drying treatment device executing an on or off operation in a temperature interval,

• when a temperature in the clothes drying treatment device reaches an upper limit value TDx of the temperature interval under an action of the heating device, the clothes drying treatment device turns off the heating device and the heating device stops heating;
• wherein,
• the upper limit value TDx of the temperature interval decreases with an increase of a number of off times x of the heating device, wherein
• when the temperature in the clothes drying treatment device decreases to a lower limit value TTz of the temperature interval at a zth time, the clothes drying treatment device turns on the heating device and the heating device executes heating;
• the lower limit value TTz of the temperature interval decreases with the increase of a number of on times z of the heating device;
• the clothes drying treatment device is provided with a system on temperature TT0, the system on temperature TT0 is a set value, and the lower limit value TTz is continuously closer to TT0 with the increase of the number of on times z of the heating device;
• TT0 is determined by a liquid point temperature of liquid in clothes in the clothes drying treatment device, and TT0 is greater than the liquid point temperature;
• the clothes drying treatment device is provided with a constant C and a highest value TTS of the lower limit value of the temperature interval, the lower limit value TTz of the temperature interval is not greater than the highest value TTS, and the highest value TTS=TT0+C, where 0<C<TT0;
• the highest value TTS of the lower limit value of the temperature interval is determined by the liquid point temperature of the liquid on the clothes in the clothes drying treatment device, and the highest value TTS is the liquid point temperature;
• the clothes drying treatment device turns on the heating device when the temperature in the clothes drying treatment device decreases to the lower limit value TTz of the temperature interval at the zth time after the heating device stops heating,
• TTz and z satisfy:
• TTz=TT0+C*NA{circumflex over ( )}(z−1), where 0<N<1.
