The present invention relates to a humidity control device for indoor air which is maintained within a comfortable range of 70%. Conventional humidity control devices include a so-called cooler dehumidifier that evaporates the refrigerant compressed by the compressor when the humidity is high, and condenses the humidity of the room air to the evaporator to remove the moisture. There is a humidifying device that supplies water vapor to the room by a sonic atomizer, a steam generator, or the like, but there is no dehumidifying device that performs only dehumidifying, and a humidifying device that performs only humidifying and that does not have both dehumidifying and humidifying functions. Other moisture absorbing materials include calcium chloride, phosphorus pentoxide, silica gel, calcium oxide, etc., but these are only used as desiccants for articles that dislike humidity, and regulate the humidity of indoor air. Not something to do. In view of this point, the present invention provides a humidity control device that has both functions of dehumidifying and humidifying indoor air, and that keeps the relative humidity of indoor air within a comfortable range of 40% to 70% at all times. Is the object of the invention.

As a means for coexisting with water, a method of directly containing the water in a container,
Water-absorbing polymer substance that absorbs water to form a sol or gel,
Alternatively, there is a method of accommodating in a container together with a sponge-like porous substance that absorbs water. When the natural convection method is adopted as the means for contacting the room air, the container is formed by a film made of an air-permeable polymer material.

帰させ、さらに吸湿させることが可能となる。Since the normal relative humidity of room air is in the range of 40% to 70%, the device of the present invention has selected its constant humidity crystal material so that the room air maintains the optimum humidity in this range. It does not continuously absorb a large amount of water and overflow, or release a large amount of water and deplete water. However, if the period of high humidity or drying continues for a long time, moisture absorption or humidification is continuously performed, and excess or deficiency of water occurs,
It is necessary to provide drainage or water supply means. The apparatus of the present invention can also change the relative humidity of the constant humidity crystal material somewhat by adding heating means. Therefore, if this change in relative humidity is used, for example, when the constant humidity crystal material is too hygroscopic, it is possible to restore it to a low water content and further absorb it.
