この発明は、小屋裏等の換気を行なう換気装置に関する
ものである。DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a ventilation system for ventilating an attic or the like.
従来より、屋根に換気口を設け、この換気口を覆って屋
根の上面にカバーを設け、かつカバーの対面する側面に
換気窓を形成してなる換気装置がある。2. Description of the Related Art Conventionally, there has been a ventilation system in which a ventilation hole is provided in a roof, a cover is provided on the upper surface of the roof to cover the ventilation hole, and a ventilation window is formed on the side surface facing the cover.
換気窓からカバー内に入った外気は、換気口を通って小
屋裏に侵入し、また屋外が無風時には小屋裏の暖気は換
気口および換気窓を通って屋外に排気される。このよう
にして、小屋裏が自然換気される。Outside air entering the cover through the ventilation window enters the attic through the ventilation opening, and when there is no wind outdoors, warm air in the attic is exhausted outdoors through the ventilation opening and the ventilation window. In this way, the attic is naturally ventilated.
しかし、屋外が雨天で強風時には、小屋裏に向けて流れ
る風の圧力が大きく、換気窓からカバー内に浸入した雨
水が霧雨状となって風と共に換気口から小屋裏に浸入す
ることがあり、雨仕舞が悪かった。However, when it is rainy and windy outdoors, the pressure of the wind flowing toward the attic is large, and the rainwater that has entered the cover through the ventilation window may become drizzle and enter the attic through the ventilation opening along with the wind. It rained poorly.
この発明の目的は、屋外が雨天で強風の場合でも小屋裏
に雨水が浸入し難く、雨仕舞が向上する換気装置を提供
することである。An object of the present invention is to provide a ventilation system that prevents rainwater from entering the attic and improves rain control even when it is rainy and windy outdoors.
この発明の換気装置は、屋根に設けた換気口を覆って前
記屋根の上面にカバーを設け、このカバーの対面する側
面に一対の換気窓を設け、これら一対の換気窓間に途中

る。In the ventilation system of the present invention, a cover is provided on the upper surface of the roof to cover a ventilation hole provided in the roof, a pair of ventilation windows are provided on opposing sides of the cover, and a ventilation window is provided between the pair of ventilation windows. It is connected to a ventilation duct with an opening.
この発明の構成によれば、カバーの側面に設けた一対の
換気窓間に、換気用開口部を有した換気ダクトを接続し
たので、屋外が雨天で強風の場合、換気窓から換気ダク
ト内に侵入した風は反対側の換気窓から屋外へ排気され
る。このため、換気ダクトの換気用開口部を通って屋根
の換気口から小屋裏に侵入する風の圧力が低減し、雨水
が小屋裏に浸入し難くなって雨仕舞が向上する。According to the configuration of this invention, a ventilation duct having a ventilation opening is connected between a pair of ventilation windows provided on the side of the cover, so that when it is rainy and windy outdoors, the ventilation window can be used to connect the ventilation duct into the ventilation duct. The intruding wind is exhausted outside through the ventilation window on the opposite side. Therefore, the pressure of the wind that enters the attic from the roof ventilation opening through the ventilation opening of the ventilation duct is reduced, making it difficult for rainwater to enter the attic, improving rain control.

設した一対のダクト接続部４４とから構成されている。The cover 14 consists of an overhang provided at the ridge of the roof 10. Further, the ventilation duct 28 is composed of a duct body 29 and duct boxes 34 and 36 connected to both ends of the duct body 29. As shown in FIG. 2, the duct box 34 (36) includes a box main body 40 with an open side 38, and a ventilation opening 24 (26) that is connected to the top surface of the box main body 40 and opens upward. A cylindrical portion 42,
The box body 40 includes a pair of duct connecting portions 44 protruding from a side surface 46 opposite to one side surface 38 of the box body 40.
なお、筒部４２の上端内面には内向きに折返してなる折

ている。A folded part 48 is provided on the inner surface of the upper end of the cylindrical part 42 and is folded inward, and the duct main body 29 is connected to each of the duct connecting parts 44 by a clip 50.
第３図は、ダクトボックス３４をカバー１４の側壁３０
に取付けた状態を示した断面図である。FIG. 3 shows the duct box 34 connected to the side wall 30 of the cover 14.
FIG.
ダクトボックス３４は、ボックス本体４０を側壁３０に
開口した換気窓２０に貫通して固設されている。また、
側面１６にはルーバ５２が取付けられている。The duct box 34 is fixedly installed by penetrating the box body 40 into the ventilation window 20 opened in the side wall 30. Also,
A louver 52 is attached to the side surface 16.

レキシブルダクトにて構成されている。Further, as shown in FIG. 1, the duct box 36 is also attached to the ventilation window 22 of the side wall 32 of the cover 14 in the same manner as the duct box 34. Note that 54 is a louver. The duct main body 29, whose both ends are connected to each duct connection part 44 of the duct box 34, 36, is constructed of a flexible duct with an iron core.
小屋裏５６の換気は次のようにして行なわれる。Ventilation of the attic 56 is performed as follows.
すなわち、換気窓２０からダクトボックス３４内に侵入
した外気は、換気用開口部２４を通ってカバー１４内に
入り、さらに換気口１２を通って小屋裏５６に侵入する
。また、風向きが変って換気窓２２内に侵入した外気も
同様にして換気用開口部２６を通って小屋裏５６に侵入

カバー１４＝換気用開口部２４．２６−換気窓２０．２
２の順に移動して屋外に排気される。さらに、強風時に
は、例えば換気窓２０に侵入した外気の一部は換気ダク
ト２８を通って換気窓２２から屋外へ排気され、換気用
開口部２４から小屋裏５６へ侵入する外気の風圧は低く
なる。That is, the outside air that has entered the duct box 34 through the ventilation window 20 enters the cover 14 through the ventilation opening 24, and further enters the attic 56 through the ventilation opening 12. Furthermore, outside air that has entered the ventilation window 22 due to a change in wind direction also enters the attic 56 through the ventilation opening 26. In addition, when there is no wind, the warm air in the attic is removed from the ventilation opening 12-
Cover 14 = ventilation opening 24.26 - ventilation window 20.2
It moves in the order of 2 and is exhausted outdoors. Furthermore, during strong winds, for example, a part of the outside air that has entered the ventilation window 20 is exhausted to the outdoors from the ventilation window 22 through the ventilation duct 28, and the wind pressure of the outside air that enters the attic 56 through the ventilation opening 24 is reduced. .
このように構成された換気装置によると、屋外が雨天で
強風の場合、換気窓２０（２２）から換気ダクト２８内
に侵入した風は反対側の換気窓２２（２０）から屋外へ
排気される。このため、換気ダクト２８の換気用開口部
２４（２６）を通って屋根ｌＯの換気口１２から小屋裏
５６に侵入する風の圧力が低減し、雨水が小屋裏５６に
浸入し難くなって雨仕舞が向上する。According to the ventilation system configured in this manner, when it is rainy and windy outdoors, the wind that enters the ventilation duct 28 through the ventilation window 20 (22) is exhausted to the outside through the ventilation window 22 (20) on the opposite side. . Therefore, the pressure of the wind that enters the attic 56 from the ventilation opening 12 of the roof 10 through the ventilation opening 24 (26) of the ventilation duct 28 is reduced, making it difficult for rainwater to enter the attic 56. Finishing performance improves.
また、換気ダクト２８のダクト本体２９がフレキシブル
ダクトにて構成されているので、換気窓２０．２２の距
離や相対位置に自由に対応でき、しかも鉄芯入りである
ため夏の温度上昇によっても変形したすせず、機能が低
下しない。In addition, since the duct body 29 of the ventilation duct 28 is made of a flexible duct, it can be freely adjusted to the distance and relative position of the ventilation windows 20 and 22, and since it has an iron core, it can be deformed even when the temperature rises in summer. No deterioration in functionality.
さらに、ダクトボックス３４（３６）の筒部４２の上端
内面に折返し部４８を設けたので、雨水がこの折返し部
４８に当ってカバー１４内に浸入し難くなり雨仕舞がよ
り一層向上する。Furthermore, since the folded part 48 is provided on the inner surface of the upper end of the cylindrical part 42 of the duct box 34 (36), rainwater hits the folded part 48 and is difficult to enter into the cover 14, further improving rainwater protection.
なお、前記実施例では、カバー１４が越屋根であったが
換気筒（換気口１２を覆って屋根１０の上面に設置した
筒状の部材）等であってもよい。In the embodiment described above, the cover 14 is an overhanging roof, but it may also be a ventilation pipe (a cylindrical member installed on the upper surface of the roof 10 covering the ventilation opening 12) or the like.

果が得られる。According to the configuration of this invention, a ventilation duct having a ventilation opening is connected between a pair of ventilation windows provided on the side of the cover, so that when it is rainy and windy outdoors, the ventilation window can be used to connect the ventilation duct into the ventilation duct. The intruding wind is exhausted outside through the ventilation window on the opposite side. This reduces the pressure of wind that enters the attic from the roof ventilation opening through the ventilation opening in the ventilation duct, making it difficult for rainwater to enter the attic, improving rain control. .
