Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an indoor fog prevention structure in a building.

Conventionally, in building structures, dehumidification inside the building structure has been carried out in the form of, for example, indoor dehumidification by installing an air conditioner and using it to dehumidify and maintain indoor air conditioning. Therefore, the current situation is that dehumidification and condensation prevention devices are not built into the building structure. Therefore,
Various building materials have been developed by using materials with high moisture resistance and heat insulation properties for building materials such as ceilings and walls. Areas with isothermal changes were prone to condensation, which led to corrosion of building materials. In addition, dew condensation easily occurs on indoor ceilings, such as areas near windows and walls facing the outside, and condensation condenses on clothes, etc., but no suitable countermeasures have been taken.

In order to solve the above problems, this invention communicates the inner pipe of the double pipe with the outside air, communicates the gap between the inner pipe and the outer pipe with the room, and utilizes the temperature difference between the outside air and the indoor air. It is an object of the present invention to provide an indoor fog prevention structure which can prevent indoor fog condensation by causing dew to condense on the inner pipe.

If the embodiment of this invention is described in detail based on the drawings, the building is a building, (B) is a balcony, and ICI indicates the construction location of the present invention. (1) shows the wall, and 10) shows the outside.

(Il is indoor. (2) indicates the outer tube, (1) is the inner tube. The outer tube (2) is a vinyl tube for example, has an outer diameter of about 100 mm, and has a ventilation hole (4 ) are installed in large numbers in the upper half 1 to ventilate the room.
Support the inner pipe (3) on the outer pipe with stainless steel screws (5) and install it.The inner pipe (3) opens to the outside air, and the openings (6) become the rain wall and north wall. This is because the dehumidifying and condensing effect of the present invention is large when the difference in temperature between the cold outside air and the indoor air is large, especially in winter. The space between the pipe (3) and the outer pipe (2) is caulked with a heat insulating material (7) to prevent outside air from entering in the appropriate places.In addition, both the inner pipe (3 and the outer pipe <2>) are slightly sloped for drainage. Attached is the inner pipe (3) and outer pipe (2) on the drain side.
A small diameter drain pipe (6) is drilled into the caulking insulation material (7) between the wall and the wall so that water can drain to the outside of the wall. The installation location of the present invention inside a building is mainly the ceiling of a hallway, and similar locations are installed in the construction of a general home, but the installation location will be selected as appropriate. Outer w (=) and inner tube (3
) It is supported with stainless steel screws (5), and is supported at two places on the left and right sides in the longitudinal direction of the pipe at appropriate intervals (e.g.
The outer tube (2) is hung from the ceiling using a hanging tube (9). The interval between the hanging bands (9) is also, for example, 5Gam.
Or set it up as appropriate. After the outer pipe (2) is installed, its outside is surrounded by a perforated board (6), and the humid air in the room passes through the holes in the perforated board (2), and then through the ventilation holes (4) in the outer pipe (2). It passes through and touches the inner tube (3). In building construction, etc., it is also possible to install branch pipes from ceiling pipes in corridors into each room. However, the tips of the branch pipes should also be opened to the outside air, and the gap between the inner pipe (3) and outer pipe (2) should be filled with heat insulating material (n
Caulk with.

In addition, if necessary, the lower half of the outer tube (2) may be covered with anti-fouling material (
(b) Methods of preventing condensation may also be considered. The inner tube (3) has m
In addition to steel pipes with high conductivity, aluminum pipes, titanium pipes, steel pipes, cast iron pipes, etc. may also be used.

The outer pipe (2) may be semi-circular in the lower half since it only needs to act as a gutter and drain water, but for ease of construction, a full-circle vinyl pipe is used to Stomata (4)
There is no problem with ventilation with only a chisel, and hole processing is easy, so
The upper half will be constructed with perforated vinyl pipe.

The embodiment of the present invention is constructed as described above, and since the openings (6) (6) at both ends of the inner tube (3) are open to the outside air, it is suitable for use during cold weather, morning and evening, or ,
During the cold winter season, as the outside air blows through the inner pipe (3), the temperature (tl) inside the inner pipe (3) quickly becomes equal to the temperature of the outside air. On the other hand, the air temperature (h) in the gap between the outer wall of the inner tube (3) and the outer tube, which are in contact with the indoor air through the ventilation holes (4) and the perforated board (2), is room temperature. Therefore, the outer wall of the inner tube (3) is (L,), !
Q The inner wall becomes (1+), and a temperature difference occurs, but because of the high thermal conductivity of the tube material, and because of the ventilation of the outside air inside the inner tube (1.3), the outer wall of the inner tube (3) also rises. becomes. Therefore, the inner tube (
3) When the temperature (41) of the outer wall is below the dew point of the indoor air, condensation occurs all over the outer wall of the inner tube (3), and the indoor air that comes into contact with the inner tube (3) is cooled and This convection is repeated one after another as it is replaced by warmer air, and the air on the west side of the inner tube (3) is also ventilated by the outside air, so the fogging phenomenon on the outer surface of the inner tube (3) is 'continuous'. The condensed mist then becomes water droplets and enters the outer tube (2).
), and further travels inside the outer pipe (2) and is drained to the outside through the drain pipe (8). Although the drain port of the drain pipe (8) is open to the outside air, it is smaller than the diameter of the inner pipe (3), so the intrusion of outside air can be considered to have no effect.

As for the flow of indoor air, high-temperature air flows toward the ceiling, so the indoor air comes into contact with the double pipe structure installed on the ceiling smoothly, and the spread of moisture is prevented through small openings. Even if it is installed on the ceiling of a hallway, if there is a small opening in the room and hallway, the humid air will spread out.
It easily passes through the holes in the perforated board (6) and comes into contact with the inner tube (3). Due to the above-mentioned air flow, fog condensation on the outside of the inner tube (3) occurs continuously, and there is no condensation on the ceiling, u-glass, g-glass, etc.

The present invention is incorporated into the construction structure as described above to prevent fogging phenomenon indoors. In particular, during the cold winter months, there is a large temperature difference between the outside air and the indoor air heated by a stove, etc., so the effect is remarkable, and unlike dehumidification such as air aim, it Therefore, there is not only no energy consumption and maintenance costs, etc.
It has the effect of protecting building materials due to natural adjustment. As buildings become more airtight, the effects of the present invention will further increase.
