Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for discharging moisture inside a building to the outside.

[0002]

2. Description of the Related Art In recent years, due to improvements in building materials and structures of windows and doors, the airtightness inside buildings has become extremely high. Therefore, if the windows and doors are closed for a long time, moisture inside the building will not be discharged to the outside.

Originally, the cause of indoor humidity in buildings was (1)
Humidity in the air of natural environment, (2) Humidity emitted by human body, living things, etc. (3) Humidity emitted by living (cooking, washing,
Bathing, etc.), (4) Heating appliances that do not have an exhaust stack to the outside (gas and kerosene as fuel), (5) Indoor ornamental plants, etc. If it is not discharged promptly to the outside of the room, it will significantly impair the living environment.

Particularly in cold regions, windows and doors are often kept closed for a long time, and the interior of a building is continuously heated for a long time. Due to the large temperature difference between the outside and the inside of the warm building, the phenomenon of dew condensation on the inner surface of the boundary wall becomes severe, which causes significant damage to the living environment, such as corrosion of the materials inside the building and generation of mold. .

Therefore, conventionally, as shown in FIG.
An electric ventilation fan 5 is provided at a high place near the ceiling 4 above the window 3 of the boundary wall portion 2 inside the building 1 so that moisture inside the building 1 is discharged to the outside.

[0006]

As shown in FIG. 5, moisture has a characteristic that it has a high density inside the building 1 due to its specific gravity near the ceiling 4 and near the floor 6 (at a low place). . Further, the humidity has a characteristic that the humidity becomes high inside the building 1 in a cold part of the wall 7 on the north side of the boundary wall part 2 on the south side which absorbs solar heat on a sunny day.

Therefore, it is installed at a high place near the ceiling 4,
In addition, the ventilation fan 5 provided on the boundary wall 2 on the south side does not sufficiently discharge the moisture inside the building 1 and discharges warm air near the ceiling 4, so that the ventilation fan 5 is particularly useful in cold regions. There was an inconvenience that the inside of the building 1 got colder the more it was used.

Further, since it is of an electric type, it costs electricity and the ventilation fan 5 causes noise.

The present invention has been made in view of such circumstances, and it is possible to efficiently and without lowering the temperature in the room.
Further, it is an object of the present invention to provide a device for discharging moisture inside a building to the outside without generating an electric charge and generating noise.

[0010]

In order to achieve the above object, the moisture discharging device of the present invention is provided in a through hole of a boundary wall portion which separates the inside and the outside of a building so that the inside and the outside communicate with each other. And a heat insulating cover provided so as to cover the ventilation cylinder.

Therefore, if the moisture discharging device is provided in the lower boundary of the building and on the boundary wall on the north side, the humidity inside the building is reduced due to the difference in humidity between the outside and the lower interior. Naturally discharged to the outside. Further, the thermal insulation covering the ventilation cylinder prevents the internal temperature from significantly lowering even if there is a temperature difference between the inside and the outside of the building.
