DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is an explanatory view of a bathroom R equipped with a dry ventilation device A according to the present invention.
Is installed on the ceiling of the.

The dry ventilation device A is housed in a casing C mounted vertically on the lower surface of the ceiling wall r, and a duct 1 arranged horizontally in the casing C has a fan function part 2 and a fan function part 2. , The heater function part 3 and the dehumidifying part 4 are arranged from the upstream side to the downstream side in the above-mentioned order to form a dehumidifying device D, and the upstream end of the duct 1 has a suction port through the intake air switching damper 5. 6 communicates with the external suction port 7, and the outlet 9 and the external outlet 10 are provided at the downstream end via an exhaust air switching damper 8.
Communicates with. Reference numerals 11 and 12 are louvers provided at the suction port 6 and the blowout port 9 for adjusting the suction direction and the blowing direction, respectively.

The fan function part 2 is for pumping air from the suction port 6 into the duct 1, and is thin and has a quiet cross-flow fan or a large number of annular plates laminated at a predetermined interval. It is also possible to use a disk fan that blows air by rotating the rotor.

The heater function part 3 uses a coil-shaped sheathed heater in which a heating wire is covered with a corrosion resistant metal, and has a capacity to heat the air from the fan function part 2 up to about 100.degree.

The heater function unit 3 may be any one capable of heating passing air, such as an air heater using gas combustion or hot water from a water heater.

The intake air switching damper 5 and the exhaust air switching damper 8 are for switching a suction destination and a blowing destination by rotating a butterfly type valve element about one end thereof, and a link (not shown). ),
When the switching operation is performed, the suction port 6 and the air outlet 9 are connected through the duct 1.
Alternatively, the external suction port 7 and the external blowout port 10 communicate with each other.

The dehumidifying section 4 is a ceramic fiber reinforced honeycomb active silica gel, which has ceramic fibers as a matrix, which is reacted with several kinds of chemicals to form a honeycomb shape, and silica gel as an adsorbent is chemically added thereto. It is strongly bonded by synthesis to achieve both the hygroscopicity of silica gel and the air flowability, and the ceramic fiber reinforced honeycomb active silica gel thus constructed has numerous fine pores on the entire surface. In the pores, the dehumidifying action is performed by rapidly adsorbing water vapor molecules in the air in the pores. In addition, the adsorption of steam moisture is up to about 40 wt% of the ceramic fiber reinforced honeycomb active silica gel (at a humidity of 100%), and since it does not adsorb any more, dew condensation does not occur.

When the silica gel reaches the moisture absorption limit, the moisture absorption performance can be regenerated by circulating hot dry air to release the moisture adsorbed by the silica gel into the air.

When humid air is circulated in the dehumidifying section 4, moisture in the air is adsorbed and removed by the hygroscopic action of silica gel, so that dry air can be produced.

The first embodiment of the present invention is configured as described above, and when drying clothes or the like, clothes or the like are arranged in the bathroom R with a hanger or the like at appropriate intervals to switch the intake air. When the damper 5 and the exhaust air switching damper 8 are switched so that the duct 1 is in communication with the suction port 6 and the air outlet 9 and the fan function unit 2 is operated, the humid air in the bathroom is dried and ventilated from the suction port 6. By being sucked into A and passing through the dehumidifying section 4, the moisture in the air is adsorbed by the silica gel, becomes dry air and is blown into the bathroom R from the air outlet 9 and circulates in the bathroom R. The clothes and the like can be effectively dried, while the air that has become humid due to the absorption of moisture from the clothes and the like is sucked into the drying ventilation device A again and becomes dry air and circulates in the bathroom R.

When the silica gel in the dehumidifying section 4 reaches the moisture absorption limit, the moisture absorption performance is regenerated.
When the dehumidifying section 4 is regenerated, the duct 1 is made to communicate with the external suction port 7 and the external blowing port 10 to operate the fan function unit 2 and the heater function unit 3 so that the air sucked from the outside can be removed by about 1
By heating it to 00 ° C and passing it through the dehumidifying section 4, the moisture adsorbed by the silica gel so far is transferred into the passing air to regenerate the silica gel, while the passing air becomes humid air and is released to the outside. It

The air in the bathroom R can be used during the regeneration, and in this case, the external suction port 7 and the intake air switching damper 5 can be omitted.

Further, the drying ventilation device A is not limited to the above-described drying of clothes and the like, but of course not only dehumidifies the bathroom R itself, but also ventilation of the bathroom R using the fan function part 2 and heating using the heater function part 3. Can also be used for

Although the dehumidifying section 4 is composed of the ceramic fiber reinforced honeycomb active silica gel, the dehumidifying section 4 is not limited to silica gel, but any adsorbent such as zeolite can be formed into a honeycomb shape to obtain the same as above. The effect can be obtained.
