【考案の詳細な説明】
この考案は、換気扇などの屋外に面して形成された換気
のための空気流通口から風雨が侵入するのを防止するウ
ェザ−カバーに関するものである。[Detailed Description of the Invention] This invention relates to a weather cover that prevents wind and rain from entering through an air circulation opening for ventilation, such as a ventilation fan, formed facing outdoors.
第１図はこの種ウェザーカバーを備えた熱交換形換気扇

９５８号公報に示されたようなウェザ−カバーであり、
ウェザ−カバー２は下部に開口部２ａを形成し、屋外側
吸気口１ｄおよび屋外側吸気口１ｅを覆って、雨滴が熱
交換形換気扇１の内部に侵入するのを防ぐためのもので
ある。Fig. 1 shows a heat exchange type ventilation fan equipped with this kind of weather cover, where 1 is a heat exchange type ventilation fan, 1a is a heat exchanger, 1b is an indoor exhaust port, 1c is an indoor air intake port, and 1d is an outdoor air intake. 1e is the outdoor exhaust port, 2 is, for example, Utility Model Opening 54-29.
A weather cover as shown in Publication No. 958,
The weather cover 2 has an opening 2a formed in its lower part, and covers the outdoor air intake port 1d and the outdoor air intake port 1e to prevent raindrops from entering the heat exchange type ventilation fan 1.
３は建物の外壁である。なお熱交換形換気扇１の内部に
は排気用ファンおよび吸気用ファンを収納しているが、
簡単にするため図示を省略した。3 is the outer wall of the building. Note that an exhaust fan and an intake fan are housed inside the heat exchange type ventilation fan 1.
Illustrations have been omitted for simplicity.
以上のように構成され、室内の汚染された空気を排出す

換気扇１内に浸入するのを防止する。The system is configured as described above, and while indoor polluted air is exhausted, fresh outdoor air is sucked in. At the same time, in order to reduce heat loss during ventilation, the supply air is discharged by exhaust during heating in the heat exchanger. During heating and cooling, the weather cover 2 prevents rainwater from entering the ventilation fan 1 through the outdoor intake port 1d and the outdoor exhaust port 1e.
ところで、近年高層集合住宅が増加し、とくに５階以上
の高層階においては、降雨とともに強風を伴う場合が多
く、換気扇１の運転・停止に係わらず換気扇１の内部を
通って隙間風が室内に浸入し、居住者に不快感をあたえ
るという問題点が発生している。By the way, in recent years, the number of high-rise apartment buildings has increased, and especially on the fifth floor or higher, strong winds are often accompanied by rain, and drafts can pass through the inside of the ventilation fan 1 and enter the room regardless of whether the ventilation fan 1 is turned on or off. Problems have arisen in that water leaks in and causes discomfort to residents.
この考案は以上のような従来のものの問題点を改善する
ことを目的とするもので、風圧により下部に形成した開
口部を所定角度回転して遮蔽する防風板を設けたウェザ
−カバーを提供するものである。This invention aims to improve the problems of the conventional ones as described above, and provides a weather cover equipped with a windbreak plate that rotates a predetermined angle to shield an opening formed at the bottom due to wind pressure. It is something.
以下、この考案の一実施例を第４図〜第６図により説明
する。An embodiment of this invention will be described below with reference to FIGS. 4 to 6.
これらの図において、４は風圧によりウェザ−カバー２
の下部開口部２ａを遮蔽する複数個の防風板、４ａは上
記開口部２ａに防風板４を回転自在に支持する支点ピン
、４ｂは防風板４が風圧により上部に回転し、はぼ水平
となった閉位置で防風板４を停止される上部ストッパー
、４ｃは防風板４が自重により水平位置から所定角度θ
下方に回転した開位置で停止させるストッパーであり、
ストッパー４ｂ、４ｃは開口部２ａに固定しである。In these figures, 4 is the weather cover 2 due to wind pressure.
4a is a fulcrum pin that rotatably supports the windbreak plate 4 in the opening 2a; 4b is a fulcrum pin that rotates the windbreak plate 4 upwards due to wind pressure, and is almost horizontal. The upper stopper 4c stops the windbreak plate 4 at the closed position when the windbreak plate 4 is rotated at a predetermined angle θ from the horizontal position due to its own weight.
It is a stopper that stops at the open position rotated downward.
The stoppers 4b and 4c are fixed to the opening 2a.
なお、防風板４は風圧が強まったとき容易に回転するよ
うに軽量の合成樹脂板により形成され、風圧のないとき
の静止位置では吸排気に支障を生ずることなく、風圧を
受けやすいように端部をＬ字状に曲げ、傾斜した状態で
支持されている（矢印Ａは風の方向を示す）。The windbreak plate 4 is made of a lightweight synthetic resin plate so that it can easily rotate when the wind pressure increases, and when it is at rest when there is no wind pressure, it does not interfere with intake and exhaust, and its edges are designed to easily receive wind pressure. The part is bent into an L shape and supported in an inclined state (arrow A indicates the direction of the wind).
第７図はこの考案の他の実施例を示すものであり、この
実施例は防風板４をウェザ−カバー２の下部開口部２ａ
に着脱自在に枠体５を取付ねじ５ａにより取付け、この
枠体５に防風板４を支点ピン４ａを介して支持させたも
のを示す。FIG. 7 shows another embodiment of this invention, in which the windbreak plate 4 is connected to the lower opening 2a of the weather cover 2.
A frame body 5 is detachably attached to the frame body 5 using mounting screws 5a, and a windbreak plate 4 is supported on the frame body 5 via a fulcrum pin 4a.
このように構成することにより、換気扇を取付けたのち
、強風により隙間風が換気扇を通って侵入することが判
明した場合に、防風板の取付工事を容易に行うことがで
きる。With this configuration, after the ventilation fan has been installed, if it is found that drafts will enter through the ventilation fan due to strong winds, the installation work of the windbreak plate can be easily carried out.
なお、第７図には図示省略したが、この実施例でもスト
ッパーが設けられている。Although not shown in FIG. 7, a stopper is also provided in this embodiment.
第１表は従来のものとこの考案によるものについて、風
速に対応して室内に侵入する１時間当たりの空気量を実
験により求めたもので、従来のものに比べてこの考案に
よるものは、室内に侵入する空気量が１７１０程度に減
少することを示している。Table 1 shows the amount of air that enters the room per hour corresponding to the wind speed, which was determined through experiments for the conventional model and the model based on this invention. This shows that the amount of air entering the area is reduced to about 1710.
なお、上記実施例は熱交換形換気扇の場合を示したが、
これに限るものではなく熱交換器のない通常の換気扇あ
るいは送風機のない自然対流による換気窓に用いても有
効である。In addition, although the above example shows the case of a heat exchange type ventilation fan,
The present invention is not limited to this, and it is also effective to use a normal ventilation fan without a heat exchanger or a ventilation window using natural convection without a blower.
以上のように、この考案によるときは、外壁に設置され

快感を取り除くことができる。As described above, with this invention, when a strong wind blows through an air circulation opening such as a ventilation fan installed on an exterior wall, the windbreak plate, which is normally supported by a stopper in the open position, rotates due to wind pressure and closes. Since the opening of the weather cover is covered by being supported by another stopper at the position, the draft that enters the room through the ventilation fan is weakened, and the discomfort caused to the occupants can be eliminated.
