Description

本考案は、屋内に配置された排気あるいは吸気ダクトと連結されて、雨水の屋内ダクトへの浸入を防止するための「ウエザーカバー」とも称せられる屋外フードに関する。   The present invention relates to an outdoor hood that is also called a “weather cover” that is connected to an exhaust or intake duct disposed indoors and prevents rainwater from entering the indoor duct.

従来、屋内の排気あるいは吸気ダクトと連結された屋外フードは、通常、建家の外部で下方に湾曲し先端に開口を有し、屋内ダクト内に雨が入り込まないようになっている。   Conventionally, an outdoor hood connected to an indoor exhaust or intake duct is usually curved downward outside the building and has an opening at the tip so that rain does not enter the indoor duct.

ところが、屋外フードの外面に沿って落ちる雨滴は、強風時には、先端開口から屋外フード内に逆流して入り、その内壁を伝って屋内ダクト内に入り、ダクトに取り付けられたモータ内に浸入して種々の不都合を生じることがある。   However, raindrops that fall along the outer surface of the outdoor hood flow back into the outdoor hood from the opening at the front end during strong winds, enter the indoor duct along the inner wall, and enter the motor attached to the duct. Various inconveniences may occur.

このため、従来、屋外フードには、屋内ダクトとの連結部分近くの内壁の周囲に水浸入を防止するための防止板を配置したものがある。   For this reason, conventionally, some outdoor hoods are provided with a prevention plate for preventing water intrusion around the inner wall near the connection portion with the indoor duct.

ところが、現実には、このような水浸入を防止する板を配置した屋外フードにおいても、防止板を乗り越えて雨水が屋内ダクトに浸入する場合がある。   However, in reality, even in an outdoor hood provided with a plate for preventing such water intrusion, rainwater sometimes enters the indoor duct over the prevention plate.

そのため、水浸入防止板を高くして逆流する雨水が防止板を乗り越えないようにする方策が採られていたが、屋内ダクトと連結する屋外フードの径を大きくする必要があり、そのための材料費、加工賃が高くなったり、屋外フードの雨水排除の効率が低減する問題がある。   Therefore, measures have been taken to prevent the rainwater that flows backward by raising the water intrusion prevention plate over the prevention plate, but it is necessary to increase the diameter of the outdoor hood connected to the indoor duct, and the material cost for that However, there is a problem that the processing fee increases and the efficiency of draining rainwater from the outdoor hood decreases.

この考案において解決しようとする課題は、係る流入防止板を設けた屋外フードにおいて、雨水が屋内ダクトに流入するのを確実に防止するための簡便な付加的な構造を提供することにある。   The problem to be solved by the present invention is to provide a simple additional structure for reliably preventing rainwater from flowing into an indoor duct in an outdoor hood provided with such an inflow prevention plate.

この考案は、屋内ダクトの屋外への放出開口近くで、連結部開口の内部周壁に雨水流入防止板を設けた屋外フードにおいて、前記雨水流入防止板の内側先端に、屋外フードの内部に向いた庇状板を逆L状に形成したことを特徴とする。   This device is an outdoor hood provided with a rainwater inflow prevention plate on the inner peripheral wall of the connecting portion opening near the outdoor opening of the indoor duct, and is directed to the inside of the outdoor hood at the inner tip of the rainwater inflow prevention plate. A saddle-shaped plate is formed in an inverted L shape.

この逆L状に形成したのき(庇)状板を雨水流入防止板の先端に形成することによって、屋外フードの先端開口から逆流してきた雨水は、雨水流入防止板によって止められ、屋内ダクトへの逆流雨水の流入は完全に防止できる。   By forming the reverse (L) -shaped plate at the tip of the rainwater inflow prevention plate, the rainwater flowing backward from the front opening of the outdoor hood is stopped by the rainwater inflow prevention plate and flows into the indoor duct. Inflow of rainwater can be completely prevented.

また、この雨水流入防止板を屋内ダクトとの接合部に設けた際、この雨水流入防止板を利用して屋外フードを屋内ダクトとの連結接合に利用することができる。   Moreover, when this rainwater inflow prevention board is provided in the junction part with an indoor duct, an outdoor hood can be utilized for connection joining with an indoor duct using this rainwater inflow prevention board.

この考案は、雨水流入防止板に単に逆L状にのき(庇)状板を設けることによって、屋外フード内を逆流する雨水の屋内ダクトへの流入を防止することができる。   This device can prevent inflow of rainwater flowing backward in the outdoor hood into the indoor duct by simply providing a reverse L-shaped plate in the rainwater inflow prevention plate.

以下、この考案の実施形態を実施例によって説明する。   Hereinafter, embodiments of the present invention will be described by way of examples.

図1は、断面が4角の屋内の換気ダクトAの排出口aに取り付けた本考案の屋外フード10を断面によって示す図であり、図2は図1のX−X線による正面から見た図を示す。   FIG. 1 is a cross-sectional view of an outdoor hood 10 of the present invention attached to a discharge port a of an indoor ventilation duct A having a square cross section, and FIG. 2 is a front view taken along line XX of FIG. The figure is shown.

図1および図2において、フード10は、換気ダクトAの排出口aと接合した基部開口1から、下方に湾曲して、その下端の開口2には、虫類や野鳥の侵入を防止するために、ステンレス製の網3が取り付けられている。このフード10によって、降雨の際には、雨水はフード10の外面を伝って流れ落ち、屋内ダクトA内への雨水の流入は防止されることになる。   1 and 2, the hood 10 is bent downward from a base opening 1 joined to the discharge port a of the ventilation duct A to prevent insects and wild birds from entering the lower opening 2. Further, a stainless net 3 is attached. With this hood 10, rainwater flows down along the outer surface of the hood 10 during rain, and rainwater inflow into the indoor duct A is prevented.

ところが、降雨時にはフードの外面を伝って流れ落ち雨水は、風向きによっては、下端の開口2から屋外フード10内に浸入し、さらには、基部開口1から屋内ダクトの開口aを経て、換気ダクトA内に流入し、ダクトの送風機Bを傷めることがある。   However, when it rains, the rainwater that flows down the outer surface of the hood, depending on the wind direction, enters the outdoor hood 10 from the lower end opening 2, and further passes from the base opening 1 through the indoor duct opening a to the inside of the ventilation duct A. May flow into the fan and damage the blower B of the duct.

4は、この下端の開口2から屋外フード10内に浸入した雨水が基部開口1から排出口aを経て換気ダクトA内に流入するのを防止するために、屋外フード10の基部開口1に設けられた雨水流入防止板を示す。   4 is provided at the base opening 1 of the outdoor hood 10 in order to prevent rainwater that has entered the outdoor hood 10 from the opening 2 at the lower end from flowing into the ventilation duct A from the base opening 1 through the discharge port a. The rainwater inflow prevention plate is shown.

この雨水流入防止板4は、これを拡大して示す図3のように、屋内ダクトAの排出口aと接する屋外フード10の基部開口1の内周に、開口の内側に半径方向に向かって形成され、屋外フード10と溶接されている本体41からなり、この本体41の先端に一体的に屋外フード10の内方に向かって形成されている「水返し」42を形成している。この「水返し」42によって、屋外フード10内に浸入した雨水は跳ね返されて、屋内ダクトA内に浸入することはない。   As shown in FIG. 3, the rainwater inflow prevention plate 4 is enlarged toward the inner periphery of the base opening 1 of the outdoor hood 10 in contact with the discharge port a of the indoor duct A, and radially toward the inside of the opening. The main body 41 is formed and welded to the outdoor hood 10, and a “water return” 42 formed integrally toward the inside of the outdoor hood 10 is formed at the tip of the main body 41. By this “water return” 42, rainwater that has entered the outdoor hood 10 is rebounded and does not enter the indoor duct A.

また、この雨水流入防止板4は、その本体41に取り付け穴を設け、これに取り付けボルト5を通すことによって屋内ダクトAとの接合に利用することができる。   The rainwater inflow prevention plate 4 can be used for joining with the indoor duct A by providing a mounting hole in the main body 41 and passing the mounting bolt 5 therethrough.

図4は、本考案の屋外フード10と屋内ダクトAとの他の接合態様を示す。この例の場合は、雨水流入防止板4の外面にL字型の取り付け具6を溶接によって設け、これを利用してボルト5によって、屋内ダクトAに取り付けることもできる。   FIG. 4 shows another joining mode of the outdoor hood 10 and the indoor duct A of the present invention. In the case of this example, an L-shaped attachment 6 is provided on the outer surface of the rainwater inflow prevention plate 4 by welding, and this can be used to attach to the indoor duct A with the bolt 5.

上記実施例においては、ダクトおよび屋外フードの断面形状が4角形のものついて説明したが、4角形に限らず4角形以外の多角形および円形のものにでも適用できる。   In the above embodiment, the duct and the outdoor hood have been described as having a quadrangular cross-sectional shape, but the present invention is not limited to a quadrangular shape but can be applied to polygons other than the quadrangular shape and circular shapes.

本考案の屋外フード側面を断面によって示す。The side surface of the outdoor hood of the present invention is shown by a cross section. 図1のX−X線から見た正面図を示す。The front view seen from the XX line of FIG. 1 is shown. 雨水流入防止板の屋外フードと屋内ダクトとの取り付け状態を示す。The attachment state of the outdoor hood and indoor duct of the rainwater inflow prevention plate is shown. 雨水流入防止板と屋内ダクトとの取り付け状態の他の形態を示す。The other form of the attachment state of a rainwater inflow prevention board and an indoor duct is shown.
