Description

[Detailed description of the invention] [Industrial field of application] The attached ventilator according to the invention is used for ventilation of buildings such as houses and buildings.

[Prior art and its drawbacks] As shown in Fig. 6, there is an attached aerator that has an air inlet/outlet made of multi-stage blades formed at the bottom of a face plate that is the main body, and a wind barrel provided on the back of the face plate. In this conventional device, the face plate and wind barrel are molded separately, the wind barrel is fitted into the face plate from the back, and the gap around the wind barrel is filled with adhesive.

Such ventilators are attached to the building structure by burying the flange part inside the outer wall 21 of the building, but with conventional ventilators, rainwater around the wind barrel during rainfall flows into the face plate from the adhesive failure point. The rainwater that has entered penetrates into the outer wall 21 through the flange of the face plate.

Therefore, the building structure has the disadvantage of being subject to rapid corrosion due to seeping rainwater, which can damage the building.

In addition, the blades through which rain and snow can enter are only provided on the face plate, so even if there is a wind body, it cannot be said that it is sufficient to prevent rain and snow from entering. Since the air inlet/outlet is integrally molded with the face plate, it cannot be removed or replaced and has the disadvantage of being difficult to clean.

[Purpose of the invention] In this invention, the face plate and wind barrel are integrally molded, so rainwater and snow drainage never enters the exterior wall, and rain and snow can be removed by attaching it to the face plate. This is achieved not only by the grill plate installed in the wind barrel, but also by the demister installed inside the wind barrel, which sufficiently prevents rain and snow from entering.Moreover, by fitting the grill plate and demister from the front of the face plate, these To provide an attached ventilator that is easy to assemble, relatively easy to remove, and can be easily replaced and cleaned when soiled.

[Means of the present invention] In order to achieve the above-mentioned object, the mounting ventilator according to the present invention includes a front plate having a substantially lower flat portion formed at the front portion of the frame portion having an outward flange at the rear edge, which is formed on the back side of the front plate. A wind barrel with an open top and an inner bottom sloping forward and downward is provided by integral molding with the face plate following the opening of the face plate, so that outside air enters the wind barrel from the top and exits to the rear. A demister consisting of many upper and lower blades is fitted from the front and installed.
In addition, a grill plate consisting of a large number of upper and lower blades is fitted from the front into the opening of the face plate so that outside air enters from the bottom and escapes to the rear. The structure is closed with a closing plate installed in the area.

[Operation of the present invention] In the present invention, the face plate and the wind barrel are integrally molded, and the inner bottom of the wind barrel is slanted forward and downward, so rain and snow inside the wind barrel can drain from the lower part of the face plate. Falling outside from the front edge of the frame.

In addition, rain and snow are not only removed by the blades of the grill plate on the face plate, but also by the demister in the wind barrel, so they will not enter the room unless there is a rainstorm or blizzard.

Further, the demister and the grill plate can be fitted into the wind barrel and into the opening of the face plate sequentially from the front, and conversely, the grill plate and the demister can be removed from the front in that order.

[Example] Next, an example of the present invention will be described using a specific example shown in FIGS. 1 to 5.

In the figure, reference numeral 1 denotes a cover body made of synthetic resin, and a frame 3 is formed around the outer periphery of a face plate 1a having an opening 2 in its lower half, and an outward flange 4 is formed on this frame 3.

Reference numeral 5 designates a wind trunk portion in which an upper portion 6 formed following the opening 2 opens at the rear of the face plate 1a, and the bottom portion 5a is sloped downward toward the front, and is molded integrally with the face plate 1a. .

7 is a synthetic resin grill plate fitted from the front into the opening 2 of the face plate, and has multi-stage blades 8;
In addition, each blade 8 has a longitudinal side surface having a structure in which a rearward protruding portion 8b is formed at the rear upper end of a forward inclined portion 8a, and an air circulation portion is formed between the upper and lower blades.

Thus, the grill plate 7 has its lower edge connected to the face plate 1.
Fit it into the engagement groove 9 formed on the upper surface of the lower frame part of a,
Further, the engaging groove 10 formed on the upper edge is elastically engaged with the downward engaging portion 11 formed on the upper edge of the opening 2 in the face plate, and the face plate is attached to the face plate.

Reference numeral 12 denotes a synthetic resin demister that is fitted into the wind barrel from the front and has multistage blades 13, each blade 13 having an upward baffle piece 13a at the front end of the horizontal piece and a downwardly facing baffle piece 13a at the rear edge. A baffle piece portion 13b is formed, and the space between each blade serves as an air circulation portion.

Further, a front-projecting closing plate 14 is provided at the upper part of the demister 12.

Therefore, the demister 12 has its lower edge connected to the wind barrel 5.
The front end of the closing plate 14 is fitted into an engaging groove 15 formed on the inner bottom of the grill plate 7, and the front end of the closing plate 14 is elastically engaged with the lower surface of a rib 16 protruding from the upper rear surface of the grill plate 7.

The mounting ventilator according to this embodiment is attached to a building by embedding the flange 4 into the outer wall 21 of the building structure 20 as shown in FIG.

The indoor and outdoor air is supplied through the grill plate 7 and the demister 12.
The air flows through the space between each of the blades 8 and 13,
When it rains or snows, outside air accompanied by rain or snow enters the wind barrel 5 from the grill plate 7, and at this time most of the rain or snow adheres to the blades 8 of the grill plate and is removed.

Rain and snow that cannot be removed are transferred to the next demister 1.
2, it is removed by the blade 13 having the baffle plates 13a and 13b, and it remains at a level that only slightly penetrates into the room during a rainstorm or blizzard.

However, the raindrops and snow removed by the grill plate and demister accumulate in the wind barrel 5, but the wind barrel 5 is integrally molded with the face plate 1a, and the inner bottom of the wind barrel is sloped downward toward the front. Therefore, all drainage such as rainwater inside the wind barrel falls to the outside from the front edge of the lower side 3a of the frame.

Therefore, rainwater and snow drainage does not enter the outer wall of the building structure as in the case of conventional methods.
It can improve the durability of buildings.

In addition, since both the demister 12 and the grill plate 7 are fitted from the front into the wind barrel and into the opening of the face plate using elasticity, they can be forcibly removed from the front, making replacement and cleaning easy. .

[Effects] As mentioned above, according to the present invention, rain and snow are sufficiently removed by the grill plate and the blades of the demister, and the rain and snow that has entered the wind barrel is drained from the front edge of the lower frame of the face plate. Since it does not leak outside or invade the exterior walls, it has the advantage of extending the life of the building and making it easier to install and replace grill plates and demisters.
