Description

[Detailed Description of the Invention] The present invention relates to an air supply and exhaust system for a combustion machine.
The purpose of this is to make it possible to project the air supply/exhaust top to the outdoors by using the ventilation openings on the wall, and to ensure that the air supply/exhaust system can supply and exhaust air.

An embodiment thereof will be described below with reference to the accompanying drawings.

In the figure, reference numeral 1 denotes a ventilation hole cover attached to a ventilation hole 3 on a wall surface 2, and this ventilation hole cover 1 has a raised portion 4 on its periphery.
It is formed into a picture frame shape. Also, ventilation vent cover 1
is provided with an opening 5 for ventilation and a mounting opening 7 for a supply/exhaust top 6 inclined at an angle of about 5 degrees in the vertical direction. Reference numeral 8 denotes a frame plate, which is welded to both sides of the ventilation port cover 1. 9
is a joint plate for thick walls, which is used by screwing to the frame plate 8 when the wall is too thick to be covered by the frame plate 8 alone. Reference numeral 10 denotes a hood partition plate, which is screwed to the frame plate 8 since the above-mentioned thick wall joint plate 9 is usually not provided. 11 is the hood, air supply and exhaust top 6
As shown in Fig. 2, the air supply port 12 and exhaust port 13 are separated and supported.The bent portion 14 prevents snow and rain water from flowing in from the top, and the air supply and exhaust top The pressure from above the 6th end is released through the R portion. Reference numeral 15 denotes a hole for passing through the air supply/exhaust top provided in the hood 11, and is sealed with a rubber gasket 16. 17 is an opening/closing plate for opening/closing the opening 5 of the ventilation port cover 1; 18 is an opening/closing knob thereof; 19 is a ventilation member covering the lower opening of the hood 11; It is also made of wire mesh or the like with a slightly larger opening. And this breathable member 19
The hood 11 is provided with rising pieces 20 on both side edges thereof.
Also, it can be attached to the frame plate 8 or the like.

In the air supply/exhaust system constructed as described above, first, the air supply/exhaust top 6 is fitted into the mounting opening 7 of the ventilation port cover 1, and then the frame plate 8 and the hood partition plate 10 are screwed together. Then, the hood partition plate 10 and the hood 11 are screwed together, and a breathable member 19 is screwed to the lower openings of both members 10 and 11 so as to cover the openings. After that, the exhaust port 13 of the air supply/exhaust top 6 is made to protrude from the hole 15 of the hood 11, and the gap with the air supply/exhaust top 6 is sealed with a rubber gasket 16. As a result, the air supply/exhaust top 6 consists of the ventilation opening cover 1 and the hood 11.
It will be fixedly supported in several places. Next, the ventilation unit with this supply/exhaust top 6 attached is inserted into the ventilation port 3 and installed. First, remove the ventilation port member (loudry) attached to the ventilation port 3, and insert the frame 8 of the ventilation unit here. , ventilator cover 1
from the front side to the ventilation port 3 with wood screws to complete the installation. At this time, in this embodiment, the ventilation unit is held in the ventilation opening 3 by the presence of the upper and lower ends of the frame plate 8 and the hood partition plate 10, so there is an advantage that the installation work including screwing can be done by one person. be.

On the other hand, in the air supply/exhaust system installed in this manner, the air supply port 12 of the supply/exhaust top 6 is located inside the hood 11, and the exhaust port 13 is located outside the hood 11, so that the combustion exhaust gas is transferred to the air supply port 12. There will be no chance of contamination.

Further, the lower opening of the hood 11 is provided with the breathable member 1.
9, it is possible to prevent the intrusion of birds and insects, and it is also possible to prevent the adverse effects caused by these intrusions, such as clogging of the air supply port by bird's nests. Furthermore, the breathable member 19 has the effect of attenuating the wind that tries to enter the hood 11, for example, the wind that hits the wall and blows up, thereby stabilizing the air supply performance. In particular, in this embodiment, the breathable member 19
Since the aperture ratio of the air supply and exhaust top 6 is approximately equal to the air supply port area of the air supply/exhaust top 6, that is, the aperture ratio is made small, the resistance to wind increases and is effective.

Furthermore, since the hood 11 of this embodiment is configured to be attached to the ventilation cover 1 via the connecting plate 9, it can be attached at an optimal position depending on the thickness of the wall 2, that is, at a position based on the roof side of the wall 2. can. Therefore, the distance between the lower end of the hood and the wall can be kept constant, and even if the thickness of the wall 2 is different, the lower opening of the hood 11 can be covered with the same size breathable member 19. There are advantages.

In this way, the present invention allows the air supply and exhaust tops to be brought outside using the ventilation openings, so there is no need to make holes in the house, and moreover, the air supply and exhaustion tops can be led out using the hoods of the ventilation openings. Since the air intake and exhaust ports are separated, there is no possibility that exhaust gas will mix with the air supply. In addition, the lower opening of the hood is covered with a breathable material, so birds and insects will not get in and obstruct air supply and exhaust.
The effect is great.
