Description

[Technical field] The present invention relates to a ventilation structure for a building in which indoor air is prevented from entering a wall to cause dew condensation.

[Background Art] Conventionally, there is known an air cycle house in which an in-wall ventilation passage for ventilating air in a wall and an indoor ventilation passage for ventilating indoor air are connected to each other. If it is included, there is a problem that dew condensation occurs on the inside of the wall or the back of the hut.

[Purpose of the Invention] The present invention has been made in view of the above circumstances. The purpose of the present invention is to ventilate the inside of a wall and the inside of a room and to allow humid air inside to enter the inside of the wall. It is to provide a ventilation structure for a building that does not generate dew condensation.

DISCLOSURE OF THE INVENTION The ventilation structure of a building according to the present invention has a structure in which air under the floor 1 is applied to the wall 2 of the building.
The in-wall ventilation channel 3 for venting the inside and the indoor ventilation channel 5 for venting the room 4 are formed separately, and the in-wall air exhaust port 6 of the in-wall ventilation channel 3 and the indoor air of the indoor ventilation channel 5 are formed. The exhaust port 7 is provided separately, and the above-mentioned object is achieved by this configuration. That is, since the in-wall ventilation flow path 3 and the indoor ventilation flow path 5 are separated, and the in-wall air exhaust port 6 and the indoor air exhaust port 7 are separated, fresh air under the floor 1 and having a relatively constant temperature is provided. Thus, although the entire building can be ventilated, even if the air in the room 4 contains moisture, it does not enter the wall 2 to cause dew condensation.

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

The wall 2 of the building is a double wall, and the wall 2 communicates with the underside of the floor 1 to form an in-wall ventilation flow path 3 for ventilating the air under the floor 1 into the wall 2. The upper end of the ventilation passage 3 in the wall communicates with the attic 11. Further, the floor 1 is provided with a lower ventilation port 8 communicating with the room 4, and the ceiling 9 of the room 4 is provided with an upper ventilation port 10.
Is provided to form the indoor ventilation flow path 5. In the embodiment shown in FIG. 1, an exhaust duct 13 is provided on the roof 12 of the building.
Is installed, and the exhaust duct 13 is branched inside to communicate with the in-wall ventilation passage 3 through the in-wall air exhaust port 6 and the indoor ventilation passage 5 through the exhaust pipe 14. It is 7. In this embodiment, the air in the room 4 is the wall 2
Since it does not enter not only the inside but also the attic 11, the dew condensation does not occur at these places.

In the embodiment shown in FIG. 2, the upper end of the ventilation passage 3 in the wall passes through the attic 11 and communicates with the air exhaust port 6 in the wall provided in the fake. There is a door 1 at the air outlet 6 in the wall.
5 is attached. The indoor ventilation flow path 7 communicates with an exhaust duct 13 installed on the roof 12 via an exhaust pipe 14.

As shown in FIG. 3 and FIG. 4, the exhaust duct 13 is partitioned by a partition plate 16 at the central portion, and each partition chamber 17
The indoor air exhaust port 6 and the indoor air exhaust port 7 may be provided in the inside of the wall. The waterproof property may be ensured by communicating with the air exhaust port 7.

[Effects of the Invention] In the present invention, a building ventilation passage is formed by separating an inside ventilation passage that allows the inside air to ventilate into the wall and an indoor ventilation passage that vents the air inside the building. Since the air outlet in the wall and the indoor air outlet of the indoor ventilation passage are provided separately, the ventilation passage in the wall and the indoor ventilation passage are separated, and the air outlet in the wall and the indoor air outlet are separated. Therefore, even if the air inside the room contains moisture, it can condense and condense, even though the entire building can be ventilated by the fresh, relatively constant temperature air under the floor. Never.

[Brief description of drawings]

FIG. 1 is a schematic view showing an embodiment of the present invention, FIG. 2 is a schematic view showing another embodiment of the present invention, and FIGS. 3 and 4 are sectional views and partially broken perspective views showing an exhaust duct. In the figure, 1 is a floor, 2 is a wall, 3 is an in-wall ventilation flow path, 4 is an indoor space, 5 is an indoor ventilation flow path, 6 is an in-wall air exhaust port, and 7 is an indoor air exhaust port.
