At the same time, the thermostat is located at the first opening 3152, that is, the end where the heating pipe 319 is not provided. It is assumed that a large amount of thermal energy can be stored in the air intake groove 3151, and the temperature control of the thermal energy box can be postponed in cooperation with the cold steam circulation structure. The device transfers, so that the temperature of the temperature controller is not easy to increase or decrease quickly, extending the power off interval of the temperature controller, ensuring the continuous use of thermal energy, and avoiding the generation of condensed water.
