It is displayed by a moisture absorption meter 77 using a circuit 71.

In FIG. 9, heater 11 and charging circuit G
A thermoswitch 79 is connected in series to the input side of the unit 5 to detect an abnormality due to thermal runaway of the heater 11 when the moisture absorption unit 5 is drying and to turn off the power. A timer 80 is connected to turn off the power to ensure safety. However,
Slide the switch button 62 from the off position to the moisture absorption side to drive the fan 21 of the air supply unit 6, open the discharge port 2 with the shutter 50, and use the fan 21 to draw air containing moisture from the outside and circulate it through the suction port 1. The hygroscopic agent 17 filled in the hygroscopic unit 5 is sucked into the channel 3 and passed through the hygroscopic unit 5 provided in the flow channel 3.
The dry air absorbs moisture from the air, and the dry air from which the moisture has been removed is discharged to the outside from the discharge port 2. In this case, the dry air exiting the discharge port 2 is deodorized by the deodorizer 52 provided in the shutter 50.

On the other hand, for dry regeneration, insert the plug of the power cord 72 into an outlet, and in this state slide the switch button 62 to the dry regeneration side to drive the fan 21 of the air supply unit 6 and supply power to the heater 22. to generate heat. In this case, the discharge port 2 is closed by the shutter 50. Then, the fan 21 is driven and the heater 11 is energized to heat the moisture absorbent 17 and evaporate the moisture, which is then discharged from the discharge plate 16 of the drying unit 12 and is made of metal having fins 41 facing the discharge plate 16. Condensed water is generated on the plate 42 due to the difference in temperature with the outside air (ambient atmosphere), drips into the drain groove 44, and is drained from the drain hole 46 into the tank 65. In this case, since the discharge port 2 is closed, drying and regeneration of the moisture absorbent 17 and removal of moisture from the humid air by condensation are efficiently performed. In this case, air is escaping through the drain hole 46. In the present invention, the metal plate 42 having the heater 11 and the fins 41 serves as a dew condensation means 40 for removing moisture from humid air during drying. By the way, in the present invention, since the moisture generated during dry regeneration is generated as dew water and collected in the tank 65, there is no rise in humidity at the place where the moisture absorber is installed during dry regeneration, and the humidity rises to around the discharge port 2. The steam can be used to clean the iron-based deodorizer 52, which has a self-regeneration function and can be used repeatedly, which is fixed on the back side of the shutter 50.
