DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat-insulating and air-tight ventilating apparatus capable of insulating and air-tightly forcibly ventilating outdoor and indoor air of a building in a highly heat-insulated and highly airtight house.

[0002]

2. Description of the Related Art Since the climate in Japan is hot and humid in the summer, in traditional buildings, in order to prevent the building from decay due to such an environment, air inside the building is everywhere. It is devised so that the air permeability is good so that it goes all the way. However, in cold regions, conversely, it is necessary to take measures to avoid taking in the cold outside air in winter as much as possible indoors, and to improve the heating efficiency.
It is necessary to increase the cooling efficiency as part of energy saving measures such as coolers. For this reason, conventionally, in order to create a comfortable living environment, a highly heat-insulated and highly airtight building with improved heat insulation and airtightness of the building has been developed, and has been well received particularly in cold regions.

In such a building, since the inside of the building is an enclosed space, it is necessary to systematically ventilate the inside of the building. As shown in FIG. Under-floor vent 412 for communicating the air through the under-floor opening / closing damper 424, the outer ventilation layer 406 and the inner ventilation layer 4
07 and a lower-floor ventilation port 414 that communicates appropriately with a lower-floor opening / closing damper 426 in the vicinity of the lower floor of the building.
When the underfloor ventilation opening 414 and the underfloor opening / closing damper 424 and the underfloor opening / closing damper 426 are respectively opened, the air taken in from the underfloor ventilation opening 412 passes through the building 402 to the outside from the underfloor ventilation opening 414. High heat insulation and high air pressure are constructed so as to improve the air permeability inside the building 402 and to effectively use the warm or cool air in the underfloor space and to effectively prevent the occurrence of dew condensation and the like. An airtight building has been proposed.
No. 8167).

[0004]

By the way, this highly insulated and highly airtight building is an ideal living property that is warm in winter and cool in summer, but if the airtightness of the building is high, The higher the temperature, the more difficult it is to introduce fresh air in each room and to eliminate contaminated air and moisture.Therefore, indoor air becomes dirty and humidity rises, and hygiene such as mold and ticks occurs. Will cause problems.
Particularly, in the summer, the attic inside the building becomes hot due to solar heat or the like, so that it is necessary to discharge warm air from the attic to the outside.

For this reason, as shown in FIG. 13, in a gable type building 602, an attic 604 has conventionally been used.
The gable wall portion 606 is provided with an air discharge port 608 such as garbage, and an opening / closing damper 610 is provided near the air discharge port to perform natural exhaust by utilizing a pressure difference between indoor and outdoor. On the other hand, in the ridge-type building 702, since there is a risk of intrusion of rainwater or the like, as shown in FIG. 14, a dormer 706 is constructed on the roof 704, and an air outlet 708 is provided in the dormer 706. Thus, natural exhaust is performed as described above. However, having a dormer on the roof
In addition to high costs, Japanese-style buildings could not be harmonized in terms of design and landscape.

[0006] Conventionally, as shown in FIG.
A forced exhaust fan device 806 is provided near the air outlet 804 to exhaust warm air from the attic inside the building 802 to the outside. However, the forced exhaust fan 806 does not have good airtightness. In addition, outdoor cold air enters the room through the forced exhaust fan, and the forced exhaust fan itself is also poor in heat insulation, so that the outside air temperature in winter is directly transmitted through the fan, and the heat insulation performance is deteriorated. However, there is a possibility that dew condensation may occur, and the original function of a highly heat-insulated and highly airtight building is impaired, which is not preferable.

[0007] In view of the above situation, the present invention provides a compact heat-insulating and air-tight air-tight and air-tight ventilating system for buildings without the necessity of providing a bar, a dormer, etc. It is intended to provide a type ventilation device.
