Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to an exhaust system for exhausting air from an attic and a room.

[Background Art] Generally, when exhaust air from the attic and indoor air are discharged through the same exhaust route, the two types of exhaust air are mixed in the exhaust route, and water vapor contained in the indoor exhaust permeates into the attic, causing the exhaust gas to leak into the attic. There is a problem that condensation tends to form on the back side.

[Purpose of the invention] The present invention was made in view of the above points, and its purpose is to separate and discharge the attic exhaust air and indoor exhaust air so that they do not mix. To provide an exhaust system which suppresses dew condensation in the attic and allows both types of exhaust gas to be discharged to the outdoors using a single device.

[Disclosure of the invention] (Structure) The exhaust system according to the present invention has a first exhaust chamber and a second exhaust chamber separated from each other formed in the apparatus main body, the first exhaust chamber communicating with the attic, and the second exhaust chamber communicating with the attic. The two exhaust chambers communicate with the interior of the room via ducts, and the first exhaust chamber and the second exhaust chamber are each formed with a first exhaust port and a second exhaust port that are open to the outdoors above the roof. This system separates the exhaust air from the attic and the indoor exhaust so that they do not mix.

(Example 1) As shown in FIG. 1, the device main body 1 is formed into a box shape, and an attic vent 8 communicating with the attic is formed in the lower wall of the device main body 1. Inside the device main body 1, a first chamber 2 and a second chamber 3, each formed into a rectangular tube shape, are arranged side by side. Both ends of the first chamber 2 in the cylinder axis direction are open to the first exhaust ports 4 on both sides of the device main body 1, and an opening 5 that is open into the device main body 1 is formed in the center of the upper surface of the first chamber 2. has been done. On the other hand, both ends of the second chamber 3 in the cylinder axis direction are open to the second exhaust ports 6 on both sides of the device main body 1, and an opening 15 formed at the center of the upper surface of the second chamber 3
One end communicates with a duct 7 that communicates with the interior of the room. The duct 7 is independent from the inside of the device main body 1,
The indoor exhaust gas discharged through the duct 7 and the attic exhaust gas discharged through the inside of the device main body 1 are prevented from mixing. That is, the inside of the device main body 1 and the inside of the first chamber 2 act as a first exhaust chamber through which only exhaust air from the attic passes, and the inside of the second chamber 3 acts as a second exhaust chamber through which only indoor exhaust air passes. be.

That is, as shown in FIG. 2, the device main body 1 is installed on a roof 10 like a chimney, and the attic 11 and the device main body are connected through the attic vent 8 of the device main body 1. At the same time, by opening one end of the duct 7 to the indoor room 12 and communicating the indoor room 12 and the second chamber 3, exhaust gas between the attic 11 and the indoor room 12 can be communicated through the device main body 1, which is identical in appearance. These can be discharged outdoors in a separate state. Here, the device main body 1 does not necessarily need to be installed on the roof 10, and the first exhaust port 4 and the second exhaust port 6
It is only necessary to install it so that it is exposed above the roof 10.

Furthermore, as shown in FIG. 3, if the air taken in from under the floor 13 is exhausted from the main body 1 of the apparatus through the inside wall 14 and the attic 11, the air under the floor 13 can be removed from the inside wall 14 and the attic 11. can be incorporated into. Since the air under the floor 13 has relatively little change in temperature throughout the year, the room 12 can be kept cool in the summer and warmed in the winter.

(Example 2) In this example, as shown in FIGS. 4 and 5,
The first chamber 2 and the second chamber 3 are arranged vertically, and other configurations and operations are the same as in the first embodiment.

(Embodiment 3) In this embodiment, as shown in FIGS. 6 and 7, the inside of the apparatus main body 1 is separated into a first exhaust chamber 21 and a second exhaust chamber 22 by a partition plate 20. There is. The first exhaust chamber 21 has an attic vent 8 that is open in the lower wall and communicates with the attic.
A rectangular first chamber 2 is housed inside. Both ends of the first chamber 2 in the cylinder axis direction are open to first exhaust ports 4 on both sides of the device main body 1, and an opening 5 at the center of the upper surface is open in the first exhaust chamber 21. On the other hand, the second exhaust chamber 22 has an indoor ventilation opening 9 on the lower wall.
is open, and a duct 7 whose one end is open to the interior of the room is connected to the indoor ventilation port 9. A second chamber 3 is disposed within the second exhaust chamber 22, and both ends of the second chamber 3 in the cylindrical axis direction are open to both sides of the device main body 1, and an opening 15 is provided at the center of the top surface.
is open in the second exhaust chamber 22. With the above configuration, the exhaust gas from the attic is introduced into the first exhaust chamber 21 and the indoor exhaust gas is introduced into the second exhaust chamber 22 through the duct 7, and the inside of the device body 1 is separated by the partition plate 20. Because of this, the exhaust from the attic and indoors is discharged outdoors without being mixed.

[Effects of the invention] As described above, in the present invention, a first exhaust chamber and a second exhaust chamber that are separated from each other are formed in the apparatus main body,
The first exhaust chamber communicates with the attic, the second exhaust chamber communicates with the room via a duct, and the first exhaust chamber and the second exhaust chamber communicate with each other through a duct.
Each exhaust chamber is formed with a first exhaust port and a second exhaust port that are open to the outdoors above the roof, and the first exhaust chamber communicates with the attic and the second exhaust port communicates with the indoor room. Since the indoor and outdoor rooms are separated from each other, both types of exhaust air are discharged outdoors without being mixed, and the water vapor contained in the indoor exhaust does not enter the attic, preventing condensation in the attic. This has the advantage of being less likely to occur. Further, since the same device is used even though the attic exhaust air and the indoor exhaust air are discharged separately, the construction is easy and the exterior has the advantage of being sleek. Furthermore, by protruding the main body of the device from the roof, the device looks like a chimney, providing a highly decorative effect.
