本発明は換気扇に取付ける屋外フードに関するものであ
る。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an outdoor hood attached to a ventilation fan.
従来例の構成とその問題点
近年、建物の気密性の向」二に伴ない台所以外で使用す
る換気扇に対する需要が高まりつつあり、それに対して
多種多様な換気扇が増加している。Conventional configurations and their problems In recent years, as buildings have become more airtight, the demand for ventilation fans for use in areas other than kitchens has been increasing, and a wide variety of ventilation fans have been increasing in response.
その結果、それら換気扇に取付ける屋外フードも捷だ多
くの種類が必要とされている。As a result, many types of outdoor hoods to be attached to these ventilation fans are required.
以下図面を参照しながら、上述したような従来の屋外フ

屋外に排気される。In FIG. 1, 1 is a partition plate 8 that partitions the top plate 2, the front plate 3, the side plates 4, the bottom plate 6, the supply air ventilation path 6, and the air ventilation path 7.
The outdoor foot body has a 9a and 9b are gears, and 10 is an automatic wind pressure shutter provided in the exhaust air passage 7. When the ventilation fan is in operation, the outdoor air is drawn in by the ventilation fan as shown in A - + A'.
Air enters the outdoor hood main body 1 from d, passes through an air supply ventilation path 6, and is supplied indoors by a ventilation fan. On the other hand, the indoor air passes through the ventilation path 7, the gallery IJ 9b, and is exhausted outdoors.

という欠点を有していた。In the outdoor hood configured as above, when the outside wind enters the outdoor hood main body 1 when the ventilation fan is stopped,
The inside of the shutter can prevent outside air from entering the exhaust ventilation path T side. However, since the direction in which outside air enters and the suction direction of the ventilation fan are the same on the side of the air supply air passage 4, an automatic wind pressure shutter cannot be provided, so the outside wind intrudes.
発明の目的
本発明は上記欠点に鑑み、排気通風路及び給気通風路を

When the operation of the ventilation fan is stopped, the exhaust ventilation passage and the supply air passage are simultaneously blocked from intrusion of outside air.

FIG. 2 shows a perspective view of an outdoor hood according to an embodiment of the present invention. The same numbers as those in FIG. 1 indicate the same parts, and the explanation will be omitted and only the different points will be explained. That is, the difference from the conventional example shown in FIG. 1 is that the exhaust ventilation passage 7
A shutter 10 consisting of a shutter 10a and a shutter 10b with a weight 11 attached to the air supply side Nyanota 10a is rotatably installed in the middle of the partition plate 8, so that the partition plate 8 can be moved up and down. It is divided into two parts.

外に排気される。In the outdoor hood configured as described above, when the ventilation fan is in operation, the outdoor air is reduced to C-
> As shown in C', enter the outdoor hood main body 1 from the gallery IJ g 6 and enter the shack 1 on the air supply side of the shutter 10.
Air is supplied into the room by a ventilation fan through the air supply ventilation ducts with an opening of 0 a. On the other hand, the indoor air is sucked into the ventilation fan, enters the outdoor hood main body 1 as shown in D-)D', passes through the exhaust air passage 7, opens the shack 10b on the exhaust side of the shutter 10, and discharges the gallery 1J9b. It passes through and is exhausted outdoors.

は閉じた状態を維持し、外気は侵入しない。In the outdoor hood configured as described above, when the ventilation fan is operated, the shutter 10 remains open because force is applied to the shutter in the same rotational direction for both air supply and exhaust. On the other hand, when the ventilation fan is stopped, it is maintained in a closed state by the weight 11 on the air supply side, but the outside air is
When entering from a or 9b, opposite forces act on the air supply side and the exhaust side, but since the area of the shutter 10 on the exhaust side is larger than that on the air supply side, the shutter 10 on the exhaust side The force applied to the shutter is larger, and the shutter
remains closed and no outside air enters.
