The temperature detector 72 and the air pressure detector 74 transmit the temperature value and the pressure value obtained through detection to the control unit 50, respectively. The control unit 50 controls the operation of the heater 31 and the blower 32 according to temperature and pressure values. In this way, it is possible to maintain the temperature and pressure of the hot air passing through the air passage 60 within a predetermined range, thereby increasing heating and insulation efficiency.

Referring to FIG. 5 , in Example 2, the return duct 40 passes between the second side 12 and the heat insulation unit 20, and the heat insulation unit 20 insulates heat from the return duct 40 and returns it.
