By the way, the adsorbent 1 uses the original particles of the adsorbent as they are, is accommodated in the adsorbent flow space 5 by the filters 4 upstream and downstream of the air flow, and passes only the air.

A part of the adsorbent 1 that has absorbed moisture is taken into the adsorbent passage 12 from the adsorbent intake section 11 and heated by the adsorbent regenerating means 13 to desorb the adsorbed moisture and regenerate it. Is done. Regenerated adsorbent 1 is adsorbent return unit 1
4 returns to the adsorbent flow space 5. In addition, steam generated by the regeneration is discharged from the steam passage 21.

As described above, since the adsorbent 1 is circulated and the particles of the adsorbent 1 are made to flow together with the processing air to perform the adsorption, the moisture is desorbed from the adsorbent 1 and the regeneration is performed. The dehumidifying ability is continuously exhibited.

An embodiment that embodies the configuration of the schematic diagram of FIG. 1 will be described below with reference to the drawings.

(First Embodiment) FIG. 2 shows a side cross-sectional configuration diagram of a dehumidifier according to a first embodiment of the present invention. In addition to the configuration shown in the schematic diagram of FIG. 1, a fin-shaped heat conductive plate 13b is heated by a heating means 13a such as a heater as an adsorbent regenerating means 13, and the adsorbent 1 passes between the heat conductive plates 13b. Is heated and desorbed moisture is regenerated.

The steam desorbed by the adsorbent regenerating means 13 accumulates around the heat exchanger 22 as condensing means installed above the inside of the dehumidifier from the steam passage 21 and the fan & motor 22a of the blowing means. The condensed water is cooled by contacting the heat exchanger 22 to which the cooling air is supplied, and accumulates in the drain tank 24 which is a condensed water recovery container through the condensed water passage 23. The cooling air that has exchanged heat with the steam in the heat exchanger 22 becomes hot air and is discharged from the cooling air passage 22b to the dehumidification target space R.

As described above, since the desorbed dehumidified water is condensed into water, unnecessary humidification is not performed with water vapor, and water can be collected and drained, thereby facilitating the handling.

(Second Embodiment) FIG. 3 shows a side cross-sectional configuration diagram of a dehumidifier according to a second embodiment of the present invention. The difference from the first embodiment of FIG. 2 is that one end of the cooling air passage 22b is communicated with the air passage 2 so that air is supplied to the air passage 2 by blowing of the fan & motor 6 and the heat exchanger 22 Also supplies cooling air. Then, the cooling air that has exchanged heat with the steam in the heat exchanger 22 becomes hot air,

The adsorbent 1 circulated to the agent regenerating means 13 is sequentially slid down and circulated while being heated on the heated heat conducting plate 13b.

As described above, when the adsorbent 1 passes over the heat conducting plate 13b, the plurality of guide grooves G can prevent the adsorbent 1 from being horizontally horizontal with respect to the sliding-down direction and other disturbances. Since uniform heating can be performed by sliding down in the uniform layer of the adsorbent 1, stable adsorbent regeneration ability can be obtained. Further, the heating area is increased with respect to the plane, and the regeneration efficiency is also improved.

(Fifth Embodiment) FIG. 7 shows a sectional side view of a dehumidifier according to a fifth embodiment of the present invention.

In the stationary state, the heat conductive plate 13b is attached to the vibration transmitting plate 15b at an angle at which the adsorbent 1 on the heat conductive plate 13b does not slide down. While being heated by the vibration of the generation means 15, the heat conduction plate 13b is sequentially slid down and circulated while being heated.

Thus, the heating time and the circulation speed of the adsorbent 1 on the heat conducting plate 13b can be controlled by the vibration.

Further, a heating means 13a is arranged on the back surface of the heat conductive plate 13b.

Then, the adsorbent 1 circulated to the adsorbent regenerating means 13 is temporarily stored on the heat conducting plate 13b in a substantially horizontal state and is heated, and when a predetermined condition (time, weight, etc.) is reached, the heat conducting plate 13b is heated. The attitude of 13b is changed as shown in FIG. 6B, and the adsorbent 1 is slid down and returned to the adsorbent flow space 5.
Thereafter, the heat conductive plate 13b returns to the substantially horizontal position again, and the adsorbent 1 is continuously circulated by repeating the above operation.

As described above, the heating time and the circulation speed of the adsorbent 1 on the heat conductive plate 13b can be controlled by the movement of the heat conductive plate 13b.

In addition, heat conduction plate 1
Heating means 13a is arranged on the back surface of 3b.

Then, the adsorbent 1 circulated to the adsorbent regenerating means 13 is supplied to the center of the rotating heat conducting plate 13b and heated while being moved in the outer peripheral direction by centrifugal force. When it reaches the part, it is dropped downward and returned to the adsorbent flowing space 5.

As described above, the heating time and the circulation speed of the adsorbent 1 on the heat conductive plate 13b can be controlled by the rotation of the heat conductive plate 13b.

(Eighth Embodiment) FIG. 13 shows an eighth embodiment of the present invention.
1 shows a side cross-sectional configuration diagram of a dehumidifier in an embodiment. The difference from the other embodiments is that the adsorbent regenerating means 13 in the adsorbent passage 12 has an adsorbent surrounded by a wire mesh (resistor) 13c that cannot pass the adsorbent 1 but can pass water vapor and a heat conductive plate 13b. An agent regeneration area 12a is provided. In addition, in the adsorbent regeneration area 12a, a condensing plate 22c that is in contact with the cooling air passage 22b is provided as condensing means 22 on a side opposite to the heat conduction plate 13b with respect to the wire mesh 13c. Incidentally, the heat conductive plate 13b is arranged at an angle at which the adsorbent 1 slides down due to gravity.

With such a configuration, the adsorbent 1 circulating in the adsorbent regeneration area 12a is heated on the heat conducting plate 13b and sequentially slides down while being regenerated. Further, the steam generated by the regeneration passes through the wire mesh 13c and accumulates in the steam passage 21 between the condensing plate 22c and the condensing plate 22c cooled by the air passing through the cooling air passage 22b to become condensed water. The liquid is dropped and stored in the drain tank 24.

As described above, by the distance between the heat conducting plate 13b and the wire mesh 13c in the adsorbent regenerating area 12a, it is possible to circulate the adsorbent 1 with a uniform thickness of the adsorbent layer on the heat conducting plate 13b, thereby regenerating the adsorbent 1. Thus, the adsorbent regeneration area 12a can be made compact. Further, by adjusting the adsorbent outflow area in the adsorbent return section 14, the adsorbent circulation amount can be easily controlled.

(Other Embodiments) A spot humidifier that humidifies only the portions that need to be humidified by the steam generated by the present apparatus may be used. For example, if it is used for humidification only around the bedside of the bedding, it is preferable because local humidification can be performed without changing the absolute humidity (total water content) in the room.

In the above-described embodiment, the air is sucked from the space R and the dehumidified air is blown out to the same space R. However, the air is not limited to the same space. It may be dehumidified and blown out to another space B.
