A drain pan 10 is arranged below the heat exchanger 9, and a drainage tank 11 is arranged below the drain pan 10. The heating means 5 is formed of an electric heater in which a finned tube 12 is disposed on an outer skin. By arranging the finned tube 12 on the outer skin,
There is an effect that the efficiency at the time of heating the air can be improved and the power consumption related to the electric heater can be reduced. The heating means 5 may be formed by a PTC (Positive Temperature Coefficient) heater (not shown) in which the amount of heat increases as the amount of passing air increases.
In the air passage 8, first humidity detecting means 28 for detecting the humidity of the air after passing through the moisture absorbing / desorbing material layer 6 is arranged. Second humidity detecting means 29 for detecting the humidity of the air in a room is arranged.

An air passage 8 connecting the suction port 2 and the blower 4

After passing through the non-energized heating means 5, it comes into contact with the moisture absorbing / releasing material layer 6. The air in contact with the moisture absorbing / releasing material layer 6 absorbs moisture, passes through the heat exchanger 9, and is discharged from the outlet 3 to the outside of the main body housing 1 by the blower 4 . The above is the dehumidification process, and the regeneration process is as follows. That is, in the process of regeneration, the heating means 5 is energized, and the passing air is heated to a high temperature. The moisture absorbing / desorbing material layer 6 which has sufficiently absorbed moisture is heated by the air passing through the heating means 5 to release moisture. Said sucking
The high-temperature air containing a large amount of moisture that has passed through the moisture release material layer 6 then contacts the heat exchanger 9 and is cooled.

The air sucked from the suction port 2 of the main body housing 1 is supplied to the heat exchanger 9.
After contacting and cooling the extended portion 14 of the main body 1, the blower 4 discharges the air from the outlet 3 to the outside of the main body housing 1. The heat exchanger 9 is exposed to high-temperature air containing moisture that has passed through the moisture absorbing / desorbing material layer 6 on the one hand, but farther than the high-temperature air in the other extending portion 14. Therefore, the temperature is sufficiently low enough to dehumidify the air passing through the moisture absorbing / releasing material layer 6 as a whole. As described above, in the dehumidifier of the present invention, the installed space can be dehumidified by repeating the two processes of dehumidification and regeneration.

By forming in this way, the following effects can be obtained. That is, spaces such as a closet, a closet, a clog box, and a space under a sink that are likely to contain moisture in a home are all narrow and do not necessarily have outlets for power supply. Even in such a space, by slightly opening the entrance and piercing the duct 17, dehumidification can be performed without putting the main body itself in the space.
This has the effect. Since the duct 17 is detachably formed, the duct 17 can be accommodated in the duct accommodating portion 18 of the main body housing 1 when dehumidifying a normal room, and the duct 17 is not obstructed. effective.

The heat exchanger 9 is formed so as to be inclined so that the extending portion 14 is higher than the other portions. By forming in this manner, the water or antifreeze liquid 31 heated on the lower side has a lower specific gravity and moves upward along the slope,
On the other hand, the water or the antifreeze liquid 31 cooled on the side of the extending portion 14 higher than the others has a higher specific gravity and moves downward along the slope, so that a so-called convection phenomenon occurs. Thereby, there is an effect that the heat exchange efficiency of the heat exchanger 9 is further improved. FIG. 9 is a perspective view showing another embodiment of the heat exchanger according to the present invention. The heat exchanger 9 is provided with a circulation pump 33 for circulating the water or the antifreeze 31 in the pipe 30.
