Abstract

PURPOSE:To increase moisture permeating volume and reduce moisture condensation by sending high-temperature air in an indoor high-humidity section or on the surface of exposed moisture condensation to a moisture permeable membrane and transferring dried, exhausted air to a section easily condensed. CONSTITUTION:In a dehumidifier constituted of a moisture permeable membrane such as a polydimethyl siloxane membrane or the like disposed in tension on an opening section of wall surface 4, and when the interior 9 is of high temperature and the exterior 10 is of low temperature, water vapor 11 is exhausted out of a room through a moisture permeable membrane 1 by the difference of indoor and outdoor water vapor partial pressures, while taking the air in a high-humidity section around a window 5 from an opening section 7 downward into a cover 3 of the dehumidifier by the operation of a cross flow fan 2 and sending the air upward. Then, the dried air 12 is exhausted out of an opening 8 and sprayed over to the high-humidity section around the window 5 to accelerate drying of the area around the window 5. As a result, moisture permeable volume is increased and moisture condensation can be reduced.

Description

【発明の詳細な説明】〔技術分野〕本発明は、透湿膜用いた除湿機に関するものである。[Detailed description of the invention] 〔Technical field〕 The present invention relates to a dehumidifier using a moisture permeable membrane.

[Background technology]

透湿膜のように、その前後に水蒸気の濃度差があれば、
濃度の高い方から低い方へ水蒸気が移動する部材がある
。このような部材を室内と室外の境界に設置すれば、室
内が室外に比べ高湿の場合、無動力で室内が除湿できる
ことになる。しかし、室内においても水蒸気の濃度分布
があって、本来透湿膜の室内側表面の水蒸気濃度が高け
れば高い程透湿量は増えるのであるが、必ずしも室内の
高温空気がｉ３湿膜の室内側表面に送られているわけで
は無く、時間当りの透湿量が大きくならないと云う欠点
があった。If there is a difference in the concentration of water vapor before and after the membrane, such as in a moisture-permeable membrane,
There is a member in which water vapor moves from an area with higher concentration to an area with lower concentration. If such a member is installed at the boundary between indoors and outdoors, if the humidity inside the room is higher than that outdoors, the room can be dehumidified without power. However, there is a concentration distribution of water vapor even indoors, and the higher the water vapor concentration on the indoor surface of the moisture permeable membrane, the more moisture permeation will occur. There was a drawback that the amount of moisture permeable per hour was not large because it was not sent to the surface.

さらに、室内において、より結露し易い部分があって、
このような場所に乾燥空気を送ることは結露防止の点か
ら考えて有効であるにもかかわらずなされていなかった
。Furthermore, there are parts of the room that are more prone to condensation,
Although sending dry air to such places is effective from the standpoint of preventing condensation, it has not been done.

[Purpose of the invention]

本発明は以上の点に濫みてなされたものであり、その目
的は透湿量を増大させ、結露軽減を図ることにある。The present invention has been made in view of the above points, and its purpose is to increase the amount of moisture permeation and reduce dew condensation.

[Disclosure of the invention]

この発明の要旨とするところは透湿膜によって室内空気

ある。The gist of this invention is to provide a dehumidifier in which indoor air and outdoor air are separated by a moisture permeable membrane, and water vapor moves from a high humidity side to a low humidity side through the i3'/W membrane. This dehumidifier is characterized by having an air passage that takes incoming air from a high humidity indoor area or above a surface where condensation is exposed and blows the discharged air against a high humidity indoor area or a surface where condensation appears.

以下、本発明の実施例を添付図面に沿って説明する。Embodiments of the present invention will be described below with reference to the accompanying drawings.

A cross-flow fan ■ is placed at the bottom of the indoor ■ side of the W membrane ■. This cross-flow fan (2) blows air upward from the bottom of the moisture-permeable membrane (2).

口部■である。(2) is a cover, which is arranged so as to enclose the moisture permeable membrane (2) and the cross-flow fan (2), and forms an air flow path between the inner surface of the cover (2) and the moisture permeable membrane (2). The air flow path is blown through the opening ■ below the cover ■, and the outlet is the opening ■ above the cover ■.

■は窓■の室内■側に結露している結露水である。■ is condensed water condensing on the indoor ■ side of the window ■.

なお、透湿膜■としては、ポリジメチルシロキサン膜、

As shown in Figure 1, while sending the air upward, due to the difference in water vapor partial pressure between the indoor and outdoor areas, some of the water vapor (■) passes through the moisture-permeable membrane (■) to the outside, and the remaining dry air (0) is passed through the upper opening (■). Discharge more water and spray onto the high temperature area near the window to accelerate drying of the area near the window.

〔Effect of the invention〕
