がないようにした換気口用フードに関するもので
ある。[Detailed description of the invention] (Industrial application field) This invention is for ventilation openings that prevent oil sprayed in the form of a mist from a ventilation fan from dripping onto the exterior wall of a building and contaminating it. It's about food.

（従来技術及びその問題点）一般に、この種換気口用フードは、外壁面に開

面を汚すという欠点があつた。(Prior art and its problems) Generally, this type of ventilation hood is attached to the outside wall of a building around the ventilation opening in order to prevent rainwater from entering through the ventilation opening opening on the outside wall. However, when the oil that evaporates during cooking is blown out in the form of mist along with water vapor by the ventilation fan installed in the ventilation opening, it gets mixed with dust in the air and adheres to the inside of the hood. Due to its own weight, the inner surface of the hood sag and some of it falls through the ventilation hole in the bottom plate, but the oil that has accumulated on the bottom plate runs down the outer wall surface from between the outer wall surface and the hood attachment point, and stains the outer wall surface. There was a drawback.

のである。(Purpose of the invention) In order to solve the above-mentioned problems, the present invention provides a ventilation hood that drains oil that accumulates on the bottom plate from a location away from the outside wall, thereby preventing it from staining the outside wall. The purpose is to provide

油抜き孔６₁，６₁を穿つて成る構造を特徴とする
ものである。(Disclosure of the invention) The ventilation hood according to the invention includes a frame 2 to be attached to the outer wall surface around the ventilation opening of a building, a semicircularly curved top plate 3, left and right side plates 4, 4, and a plurality of In a ventilation hood 1 which is formed by integrally assembling a bottom plate 5 with ventilation holes 51...51, a groove 6 is formed in the bottom plate 5 to surround the ventilation holes ₅₁ _... ₅₁ _. At the same time, the bottom plate 5 is bent into a V-shape to form a trough 5 ₂ , and oil drain holes 6 ₁ , 6 ₁ are bored in the grooves 6 at locations corresponding to the troughs 5 ₂ . This is a characteristic feature.

尚、底板５に穿つ通気孔５₁…５₁の面積は最も
気流の速い天板３側から順次狭くしてあり、これ
によつてフード内の空気の流れを円滑にし、フー
ド内が増圧となつて換気扇のモータに負担がかか
らないようにしてある。 The areas of the ventilation holes 5 ₁ ... 5 ₁ bored in the bottom plate 5 are sequentially narrowed from the side of the top plate 3 where the airflow is fastest, thereby smoothing the flow of air inside the hood and increasing the pressure inside the hood. This prevents any strain on the ventilation fan motor.

る。(Operations and Effects of the Invention) In accordance with the above structure of the invention, the functions and effects of the ventilation hood of the invention will be explained with reference to the illustrated embodiments.

即ち、調理中換気扇を駆動して換気を行つてい

孔６₁，６₁から地面上に落下する。 In other words, when a ventilation fan is operated to provide ventilation during cooking, evaporated oil is blown out in the form of mist by the ventilation fan and adheres to the inner surfaces of the top plate 3, left and right side panels 4, 4 of the hood. The oil drips down along its inner surface and falls onto the bottom plate 5, but the oil that has accumulated on this bottom plate enters the groove 6 and flows toward the valley ₅₂ of the bottom plate 5, and is drilled into this valley. It falls onto the ground through the dripping left and right oil drain holes 6 ₁ and 6 ₁ .

つまり、フード内面に付着した油分は一個所に
集められ、外壁面から離れた所から排出されるの
で、従来のフードのように底板に溜つた油分が外
壁面を伝つて垂れ下がり、外壁面を汚すようなこ

る必要がなく、実用的効果多大である。 In other words, the oil that adheres to the inside of the hood is collected in one place and discharged from a place away from the outer wall, so unlike traditional hoods, the oil that accumulates on the bottom plate drips down the outer wall and stains the outer wall. There is no need to regularly clean the inside of the hood, which has great practical effects.
