Description

[Detailed Description of the Invention] The present invention relates to a ventilation system for ventilating hot air and humidity from the attic of a house.

Traditional roof structures in modern Japanese houses are being reevaluated and are being re-adopted, but fire-resistant structures are required, so new building materials such as asbestos boards are being used in many places.
Fireproof materials such as asbestos boards allow heat from sunlight to pass through to the inside, so if they are used in an attic, hot air and moisture will accumulate in the ceiling and raise the room temperature, making a cooler necessary in the summer. This would go against the trend of energy conservation. In view of these points, the purpose of this invention is to provide a ventilation system that lowers the indoor temperature by naturally ventilating the hot air and humidity in the attic, making it possible to spend a comfortable summer without using electricity. It is something.

In order to achieve this purpose, the attic ventilation system for a house of the present invention is fixed to the upper part of the ventilation hollowed out part opened in the sheathing board at the required location of the ridge part of the roof, and the lower edge of both side boards is connected to the hollowed out part. a mounting frame formed lower than the opening circumferential surface of the mounting frame; a mesh frame attached to the outer periphery of this mounting frame for filling the gap between the tile and the mounting frame with mortar; At least two substantially perpendicular detour plates are provided in the spaces leading from both sides of the end plate to the inner surfaces of the both side plates, and each of the side plates has a detour plate extending from the lower inner side of each side plate toward the both side plates of the mounting frame. The ventilation system is characterized by comprising a ventilation system main body in which continuous bottom plates are formed with downward slopes toward the front and back sides, and a roof cover attached to the upper part of the ventilation system main body.

Hereinafter, the present invention will be explained based on embodiments shown in the drawings.

First, as shown in FIG. 1, a ventilation cutout 2 leading to the attic is opened in the roof board 1 at the ridge of the roof, and the mounting frame 3 is fixed to the cutout 2 with screws or the like.

Next, as shown in FIG.
Fit it around the mounting frame 3. The lower edge of the hanging portion 5a of this mesh frame 5 is cut in the shape of the tile 4 beforehand. Next, mortar is poured from the upper surface of the mesh frame 5 to fill the gap between the mounting frame 3 and the tile 4. At this time, the mesh of the mesh frame 5 becomes a core material and has the function of reinforcing the mortar filled portion.

Next, as shown in FIG. 3, a ventilator main body 6 is attached to the mounting frame 3, in which detour plates 6e and 6f are provided in spaces extending from the front and rear end plates 6a and 6b to the insides of the side plates 6c and 6d. Attach the same ventilation device body 6
The ventilation device main body 6 is fixed by passing screws 9 through the screw holes 6g of the end plates 6a, 6b and the long holes 3a of the mounting frame 3 and tightening them. After that, the end plate 6
A mesh cover 7 is attached to the ventilation openings on the front and rear surfaces of a and 6b. This net cover 7 prevents sparrows and the like from building a nest and also serves as a decoration. Further, the mesh lid 7 may be a removable type as shown in the figure or a fixed type. Finally, the roof cover 8 is placed on the ventilation device main body 6 and screwed.

Figure 4 is a cross-sectional view of the roof where this ventilation system is installed.The hot air in the attic due to reflection of sunlight, etc. is removed from the eaves lining, gables, ventilation holes in the ceiling, or between the inside and outside walls. The cold air rises due to the difference in specific gravity with the cold air taken in from under the floor, which communicates through the space, and is discharged to the outside through exhaust ports on the front and rear surfaces of the end plates 6a and 6b through a detour formed in the main body 6 of the ventilation system. In this way, the air in the attic is replaced with outside air, indoor air, or air under the floor, and it is possible to prevent the indoor temperature from rising due to the hot air in the attic.

Figures 5 and 6 are a partially cutaway longitudinal cross-sectional view and a cross-sectional plan view showing the features of this ventilation system, which simultaneously efficiently exhaust hot air and prevent the intrusion of rain and wind by means of a detour in the horizontal plane. It satisfied me. That is, the hot air rising from the attic through the hollowed out part 2 is exhausted to the outside through a detour formed by both detour plates 6f and 6e along the route shown by the arrows in FIGS. 5 and 6. Ru. Next, when wind and rain are hitting the end plate 6b of the ventilation device main body 6, the raindrops try to enter the inside of the ventilation device main body 6 from the detour plates 6e and 6f, Since the bottom plate part 6h surrounded by the bottom plate parts 3b and 3c has a slope that lowers outward, the central top part cannot be raised, or even if it does, rainwater flows toward the end plate 6a side and flows into the attic. will not enter.

As mentioned above, since the present invention has the above-mentioned configuration, the hot air in the attic increases the room temperature in the summer, making life uncomfortable and requiring an air conditioner, but this invention uses natural ventilation in the attic. This has the effect of preventing the room temperature from rising and allowing you to enjoy a comfortable summer without electricity.
