The indoor condensation prevention device 1 includes a plurality of inlet ports 3 provided at corners of a ceiling surface of an indoor room 2, a condensation chamber 4 that introduces indoor air from the inlet ports 3 via a rising portion 12, and a condensation chamber 4 that is in contact with outside air. A heat collecting plate 5 forming an outer wall of the condensation chamber; a condensing plate 6 which divides the condensation chamber 4 into upper and lower parts and has a drainage hole 15 for condensed water and protrudes from the heat collecting plate 5;
The dew condensation chamber 4 is provided with an inclined drainage plate 8 which forms the bottom wall of the condensation chamber 4 and guides water droplets dripping from the condensation plate 6 to the outside.

The inlet 3 is provided at a surrounding edge 11 that is continuous with the corner of the ceiling finishing material 9 and the inner wall finishing material 10.

The surrounding edge 11 here includes a main body part 11a in which an inlet 3 is bored and a locking part of the ceiling finishing material 9 is formed at the indoor end, and a locking part of this main body part 11a and an inlet. There is a rising part 12 that rises from between the opening 3 into the ceiling 16 and becomes the inner wall that constitutes the condensation chamber 4, and a rising part 12 that extends toward the outside of the room at a position above the inlet 3 and inside the condensation chamber 4. It is provided with an inclination, and is integrally formed with a draining part 13 having a water return part 13a forming an air flow path with the rising part 12 at the indoor end. It is made of a material with low thermal conductivity, such as foam plastic.

The dew condensation plate 6 is provided on the inner surface of the heat collection plate 5, on which a plurality of heat collection protrusions are formed on the outer surface, so as to protrude from the upper part of the dew condensation chamber 4 toward the indoor side. A dew condensation portion 14 is formed in the indoor half of this protruding portion.

The dew condensation section 14 is formed by a first vertical plate 14a extending upward from a position near the upper part of the draining part 13 formed on the surrounding edge 11 and near the outdoor side of the water returning piece 13a, and this first vertical plate. a second vertical plate 14a' provided at the outdoor side position of 14a;
The lower end of this first vertical plate 14a and the second vertical plate 14
The lower end of the first inclined plate 14b and the second vertical plate 14' connecting the upper end of a' and the base 6a of the dew condensation plate 6
and a second inclined plate 14b' which is connected to the second inclined plate 14b'.

Note that the first and second vertical plates 14a, 14a',
Drain holes 15 are formed at the corners of the first and second inclined plates 14b, 14b'.

The drain plate 8 has its indoor end engaged with the lower surface of the outdoor end of the drain section 13 formed on the surrounding edge 11 via a packing material, and is provided as a downward slope toward the outdoor side. There is. A drain port 7 is formed by the upper surface of the outdoor side end and the lower end of the heat collecting plate 5.

The indoor dew condensation prevention effect of the prevention device 1 having such a configuration is as follows: First, the hot and humid air accumulated in the corners of the ceiling surface of the room 2 is forced into the dew condensation room 4 through the inlet 3 by natural convection. will be introduced to This introduced air then comes into contact with the dew condensation portion 14 of the dew condensation plate 6.

At this time, since the dew condensation plate 6 is constantly cooled by heat conduction from the heat collecting plate 5 that is in contact with the outside air, the dew condensation part 14 is exposed to the high temperature and humidity of the room 2 introduced into the dew condensation chamber 4. The air cools and the moisture adheres to it as water droplets.

Next, among the water droplets that adhered to the dew condensation portion 14 of the dew condensation plate 6, some of the water droplets adhered to the indoor side surfaces of the first and second vertical plates 14a and 14a' and the lower surfaces of the first and second inclined plates 14b and 14b'. The water droplets flow along each surface to the lower end of each plate due to its own weight, fall on the draining portion 13 of the surrounding edge 11 and the upper surface of the draining plate 8, are guided to the drain port, and are discharged to the outside.

In addition, water droplets adhering to the outdoor side surfaces of the first and second vertical plates 14a and 14a' and the upper surfaces of the first and second inclined plates 14b and 14b' are transferred by their own weight to the lower ends of each plate along the respective surfaces. The water flows through the water drain hole 15 and falls onto the upper surface of the water drain section 13 and the water drain plate 8, and is led to the drain port 7 and discharged to the outside.

In this way, the hot and humid air that has accumulated in the corners of the ceiling of the room 2 is cooled in the condensation chamber 4 introduced by natural convection, actively inducing dew condensation, and removing moisture. Water droplets adhere to the dew condensation portion 14 of the dew condensation plate 6 and are discharged to the outside and removed.

Therefore, it is possible to prevent the room 2 from being cooled and condensing.

Any device may be used as long as it has a configuration within the range described in the column. Furthermore, the installation location is not limited to that of the embodiment described above.

〔Effect of the invention〕

An inlet is provided at the corner of the indoor ceiling where hot and humid indoor air tends to accumulate, and the indoor air is introduced into a condensation chamber that has a condensation plate attached to a heat collection plate that is in contact with the outside air. This makes it possible to inexpensively and reliably prevent indoor condensation.

That is, indoor air introduced into the condensation chamber is cooled by the condensation plate to actively induce condensation, and the moisture is separated as water droplets and discharged to the outside. Therefore, indoor air is dehumidified, and it is possible to reliably prevent dew condensation from occurring indoors.

In addition, since indoor air is introduced into the condensation room through an inlet provided at a corner of the ceiling surface of the room, natural convection can be used to introduce the room air, and no special air intake device is required. Since the condensation plate of the condensation chamber is simply brought into contact with the natural air flow in this way, the structure can be simple, and since an air intake device or the like is not required, the dew condensation prevention device can be provided at low cost.
