Description

TECHNICAL FIELD The present invention relates to a house that minimizes heat input and output from inside and outside of the house, efficiently performs cooling and heating, and has improved durability.

[Conventional technology]

In a conventional house, the habitability has been improved by disposing a heat insulating material on the wall and the like and making it highly airtight.

[Problems to be Solved by the Invention]

However, in such a house, moisture generated from the main pillars, studs, etc., and moisture generated from the occupants and heaters in the living space condense in the attic space and inside the walls, impairing the durability of the house. There was a disadvantage. Moreover, especially in the winter, the heat generated in the living space accumulates in the attic space through the ceiling, which causes a temperature difference in the living space.

[Means for solving the problem]

In view of such a point, the present invention prevents heat from entering and exiting the inside and outside of the house by forming a heat insulating layer on the outer wall and the roof, installs a heat exchanger in the attic space or underfloor space, and By sucking and exhausting air through a heat exchanger, ventilation is performed without impairing thermal efficiency to prevent dew condensation, durability is improved, and air in the attic space is forced into the underfloor space. This proposes a house that prevents the temperature difference in the living space.

〔Example〕

A house according to the present invention will be described in detail below with reference to the drawings. FIG. 1 is an explanatory view showing a typical embodiment of the above house A, where 1 is a space behind the hut, 2 is a living space, 3 is a space under the floor, and the house A is divided by a ceiling 11 and a floor 13, respectively. Is the internal space of. Reference numeral 4 is a roof heat insulating layer, and 5 is an outer wall heat insulating layer, which at least blocks heat from entering and exiting the interior of the house A, and secondarily also has soundproofness, airtightness, and fireproofness. More specifically, the heat insulating layer 4 for roof and the heat insulating layer for outer wall 5 are in the form of a board, a mat, a sheet, or a roof material and an outer wall material, respectively. Examples of the former, polystyrene board, polyurethane board, polyisocyanurate foam board, sheathing board, sheathing insulation board, wood chip cement board, wood wool cement board, glass wool mat, etc., or a composite board of these,
By arranging metal roofing materials, roof tiles, etc. on these surfaces, the roof, metal-based panels, tiles, ceramic-based panels,
The outer wall is formed by arranging ALC plates and mortar. Further, as an example of the latter, a panel integrally formed with a surface material, a heat insulating core material and a back surface material as necessary,
An ALC exterior panel, a wood chip cement panel, a wood wool cement panel, etc. are provided on the main pillars, studs, and other frames to form the outer wall heat insulating layer 5 and the roof heat insulating layer 4. A heat exchanger 6 is arranged in the attic space 1 or in the underfloor space 3 (not shown) to exchange heat between the air inside the house A and fresh outside air to suck and exhaust air. To explain further, the heat exchanger 6 allows the inside air to pass through the pipe 6a and the outside air to the pipe 6a, as shown in, for example, FIGS.
It is designed to pass through the space 6b around 6a,
The diameter and length are appropriately set according to the purpose. In addition, the intake of the outside air and the exhaust of the inside air performed by the heat exchanger 6 are performed by the wife ventilation port or the underfloor ventilation port and the heat exchanger 6.
It is done by directly connecting. The heat exchanger 6 can be arranged in either the attic space 1 or the underfloor space 3,
It is preferable to arrange so that fresh outside air is discharged to the attic space 1 and the inside air in the attic space 1 is discharged to the outside. This is because the humidity inside the house A is the back space 1
This is because the moisture easily accumulates inside, and by releasing this moisture to the outside, the occurrence of dew condensation can be prevented. Reference numeral 8 is a duct for connecting the attic space 1 and the underfloor space 3 to each other, and a fan 7 is interposed at least at one place. This duct 8 forcibly sends the warm air in the attic space 1 and fresh outside air taken in by the heat exchanger 6 to the underfloor space 3 by the fan 7, and the humidity in the attic space 1 and the underfloor space 3 is increased. By eliminating the difference, the temperature difference in the living space 2 is eliminated and the habitability is improved. Further, 9 is an intake duct, which is an attic space 1 of the duct 8.
It is connected to the side tip and collects the air in the attic space 1, and is provided as necessary. The intake duct 9 has a slit 9a on the outer circumference, as shown in FIG. 3, for example.
One or a plurality of the perforated holes are arranged, and the air is taken in through the slit 9a.
Reference numeral 10 denotes a dispersion duct, which is provided at the tip of the underfloor space 3 side of the duct 8 as needed, so that the air sent from the attic space 1 through the duct 8 is uniformly distributed in the underfloor space 3. It is effective to disperse and make the temperature uniform. The shape is, for example, as shown in FIG. 4, a pipe made of metal or plastic is formed into an antenna shape, each of which has a slit 10a of a rectangular shape, an elliptical shape, a circular shape, or a void made of a connecting tissue. Material having, for example, glass fiber, plastic fiber, mineral fiber, fibrous material such as metal fiber, polyurethane foam having an open cell structure, synthetic resin foam such as polyurea foam, porous ceramic, etc. A pipe-shaped member having a triangular shape, a polygonal shape or the like is arranged as shown in FIGS. 5 (a) and 5 (b). The air discharged from the dispersion duct 10 is used by the fan 7
Due to the pressure from the living space 2, or the space formed by the main columns, studs, etc. between the inner wall 12 and the outer wall heat insulating layer 5
It passes through 14 to the attic space 1.

The above description is only one example of the house A according to the present invention, and it is possible to form the air supply port 15 at least at one position shown by the dotted line in FIG. Further, although not shown, the heat exchanger 6 may perform suction and exhaust through a fan. Further, when a material having voids having a communicating structure is used as the dispersion duct 10, Figs. 6 (a) to (h)
It can be formed as outlined using a cross-sectional view. That is, (a) is a dispersion duct 10, which is composed only of a main body 10b made of a material having voids of a communicating structure, (b),
In the figure, (c) shows a dispersion duct 10, in which the inner surface, the outer surface, or both surfaces (not shown) of the main body 10b is covered with a breathable sheet 10c to improve shape retention, (d) to (h). The figure shows the outer surface of the main body 10b covered with a sheet-like material 10d, and the figure (d) shows the dispersion duct 10 in which slits 10e are formed.
Figures (e) to (g) show the free edge 10f on a part of the sheet 10d.
The dispersion duct 10 in which the main body 10b is exposed is shown in FIG. Note that (d) to (h)
The sheet-like material 10d in the figure may be either breathable or impermeable, but when the impermeable sheet is used in the figures (d) to (g), the slit 10e and the free end 10f fulfill a valve function. This is preferable because it allows one-way passage of air in the dispersion duct 10 to be released to the outside.

As described above, according to the house of the present invention,
Since external ventilation can be performed without heat input and output, efficient cooling and heating can be performed, and since moisture is released to the outside, condensation is prevented and durability is greatly improved. You can Further, since the temperature difference between the attic space and the underfloor space is eliminated, the temperature difference between the living spaces is eliminated and the habitability is improved. There are effects and features such as.
