Abstract

A method by which water may be extracted from the air even without a supply of electricity from a power source or even without a supply of fuel, as well as an apparatus therefor, is disclosed. The apparatus used for the method for extracting water from the air comprises at least a rotatably mounted hygroscopic moisture-absorbing rotor having at least one region through which air can pass in the direction of thickness thereof; a passage for regeneration through which air for regeneration is circulated, of which both ends are opened at the opposing two surfaces of a regeneration region, respectively, the regeneration region being a part of the moisture-absorbing rotor, at which the moisture-absorbing rotor that absorbed moisture is regenerated; and a drain hole for taking out condensed water from the passage for regeneration.

Description

TECHNICAL FIELD

[0001] The present invention relates to a method for extracting water from the air and to an apparatus therefor. More particularly, the present invention relates to a method for extracting water from the air by which water may be extracted from the air even without a supply of electricity from a power source or even without a supply of fuel, and to an apparatus therefor. TECHNICAL FIELD

[0002] As an apparatus for extracting water from the air, for example, the apparatus disclosed in Japanese Laid-open Patent Application (Kokai) No. 54-127870 is known. With this apparatus, moisture in the air is absorbed by an absorber containing a moisture absorbent. Thereafter, the absorber is heated by utilizing sunlight to desorb the moisture absorbed by the absorber, then the desorbed moisture is condensed and the resulting condensed water is taken out. With this apparatus, although the regeneration of the absorber is carried out utilizing solar heat, power is necessary for opera...

Embodiment Construction

[0027] The method and apparatus according to the present invention will now be described referring to the drawings. FIG. 1 is a partially cut away perspective view schematically showing a preferred embodiment of the apparatus according to the present invention. The apparatus (hereinafter referred to as “water extraction apparatus”) for the method of extracting water from the air according to the present invention comprises a moisture-absorbing rotor 10. The moisture-absorbing rotor 10 is rotatably mounted and hygroscopic, through which air can pass through in the direction of thickness thereof. Although the moisture-absorbing rotor 10 is in the form of disk in the preferred embodiment shown in FIG. 1, the moisture-absorbing rotor 10 is not necessarily in the form of a disk. In FIG. 1, a part of the moisture-absorbing rotor 10 is cut away in order to show the structure mounting the moisture-absorbing rotor more comprehensively. The moisture-absorbing rotor 10 may be formed of a porou...
