When the rate of change approaches 0, the clothes 2 are considered to be almost dry, and the warm air generator 6 is stopped. That is, if there is almost no change in the radiant heat from the clothes 2, it is assumed that the clothes 2 have been dried. Even if some moisture remains in the clothes 2, the clothes 2 can be naturally dried by the warm atmosphere in the drying chamber immediately after the operation is stopped. This drying process is shown in the flowchart of FIG. 4 as the operation of the control unit 10.

のフローチャートに示している。In the above structure, the radiant heat temperature from the clothes 2 detected by the radiant heat detecting means 9 and the temperature detecting means 1
Comparing with the temperature in the drying chamber 1 detected by 2
As shown in FIG. 6, since the radiant heat from the clothes 2 is large immediately after the start of drying (in this case, the radiant heat is cold and radiant heat), it is considerably lower than the room temperature of the drying chamber, but the radiant heat from the clothes 2 gradually increases as the drying progresses. When the temperature becomes smaller and approaches the room temperature of the drying chamber 1, and the drying is completed, the temperature of radiation heat from the clothes 2 becomes equal to the temperature of the drying chamber 1. Since the control unit 10 constantly monitors the radiant heat temperature from the clothes 2 obtained by the radiant heat detecting means 9 and the temperature in the drying chamber 1 obtained by the temperature detecting means, the radiant heat temperature is close to the temperature of the drying chamber 1. When the remaining operating time is over, the remaining operating time is determined, and the warm air generator is stopped when the remaining operating time ends. This process is shown in Figure 7.
It is shown in the flowchart.

ので長めに設定している。The length of the remaining operation time is determined by the temperature inside the drying chamber 1. For example, in summer, dry room 1
Since the temperature inside is high, the remaining operating time is set short, and in winter the temperature inside the drying chamber 1 is low, so it is difficult to dry, so it is set long.

By setting the remaining operation time according to the temperature in the drying chamber 1 when the temperature is near, it is possible to realize an accurate drying operation.
