However, such refrigeration cycle types still have problems such as the use of halogen-based gases that lead to environmental destruction, the tendency to increase in size due to the mounting of a compressor, and the loud noise. On the other hand, in the zeolite type, regeneration heat of 200 ° C. or higher is necessary and the efficiency is low, and the hybrid type in which these are combined has been improved by partially using the compression heat of the compressor for regeneration of the zeolite rotor. Although the range of use can be expanded, complicated air paths and mechanisms are required, and an increase in size is inevitable. Further, the water vapor collected by absorption or the like is still condensed by supersaturated cooling.

  In the second to sixth embodiments, the hygroscopic material 2 preferably contains N-isopropylacrylamide. If the hygroscopic material 2 has such a configuration, a configuration in which a first state that can absorb moisture and a second state that releases absorbed moisture can be easily realized by heat stimulation. can do.

In addition, as the hygroscopic material , a polymer hygroscopic material having desired properties is appropriately prepared using a thermosensitive polymer such as poly-N-isopropylacrylamide (PNIPAM) and its derivative, polyvinyl ether and its derivative as a material. Use it.

  In addition, in this Embodiment, although the some moisture absorption part 23 is arrange | positioned so that a center axis may be made into the perpendicular direction, the direction of installation of the some moisture absorption part 23 is not restricted to this.

  In this embodiment, a combination of the blower fan 17 and the heater 18 is used as the stimulus applying unit 5, but the stimulus applying unit may be a surface heater or a line heater embedded in the base material 13.

For example, water in a liquid state is brought into contact with the moisture absorbent material 2 in the first state, the moisture absorbent material 2 is allowed to absorb moisture, and the irritation applied to the moisture absorbent material 2 is eliminated, so that the first state is changed to the first state. 2 so that water is discharged from the hygroscopic material 2 in a liquid state. In this state, an air current is passed so as to touch the wet moisture absorbent 2. This gives moisture to the airflow.

  When used as a water making machine, the moisture in the air is absorbed by the moisture absorbent 2 by bringing the surrounding air into contact with the moisture absorbent 2 and the moisture absorbent 2 in this state is stimulated to remove the moisture from the moisture absorbent 2. Drain liquid water. Water discharged from the moisture absorbent 2 is collected in a container. In this way, liquid water can be obtained even in places where there is no water source such as a well and no rain falls.

  It is difficult for the microorganisms to survive by using only the water taken into the hygroscopic material having ionic properties. Furthermore, since the water | moisture content stored in the hygroscopic material will be exposed to 50-60 degreeC heat stimulation, when it drains, the bactericidal effect by this high temperature can be anticipated. However, in order to use the obtained water for drinking or semi-drinking (water for daily use such as washing water), it is possible to sterilize by UV light irradiation and filter bacteria by taking into account contamination of bacteria in the route after drainage. It is preferable to combine with a filter.

  For example, as shown in FIG. 16, after absorbing moisture through an air current through a hygroscopic portion 22 formed by stacking particulate, layered, or block-shaped hygroscopic materials, water discharged by stimulation such as heat is irradiated with UV light and filtered. It can be further purified through a filter and used as drinking or semi-drinking. Such a water producer can be realized by using any of the dehumidifier configurations shown in the first to sixth embodiments.

  In addition, the said embodiment disclosed this time is an illustration in all the points, Comprising: It is not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
