[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 ventilate the building in a planned manner. As shown in FIG.
16, an under-ventilated vent 412 that appropriately communicates with the under-floor opening / closing damper 424, an outer ventilation layer 406, and an inner ventilation layer 407.
Is formed near the lower part of the wing by a lower ridge opening / closing damper 426 as appropriate, and the lower floor ventilation opening 412 and the lower wing ventilation opening 414 are respectively connected to the lower floor opening / closing damper 42.
4 and the opening / closing damper 426 below the building, the air taken in from the underfloor ventilation opening 412 is used for the building 40.
It is configured to be discharged from the ventilation hole 414 under the building to the outside through the inside 2 to improve the air permeability in the building 402, effectively use the warm or cold air in the underfloor space, and effectively reduce the occurrence of dew condensation and the like. High thermal insulation, configured to prevent
A highly airtight building has been proposed (Jitsuhei 5-38167).
No.).

[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. 8, in a gable type building 602, attic 604 has conventionally been used.
The gable wall portion 606 is provided with an air outlet 608 such as garbage, and an open / close damper 610 is provided near the air outlet.
Natural exhaust is performed using the 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.
A dormer 706 is constructed on the roof 704, and an air outlet 708 is provided in the dormer 706, and natural exhaust is performed as described above. However, providing a dormer on a roof increases costs, and in Japanese-style buildings, there is a risk that harmony cannot be achieved from the viewpoint 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.

Further, conventionally, an opening / closing drive motor 902
As a result, the opening / closing door 904 is opened and closed, and the pressing roller 906 projects at the closed position of the opening / closing door 904 to hold the opening / closing door 904 in the closed position.
0 has been proposed. However, this ventilation device 90
0, as shown in FIG.
08 must be connected, the device becomes large, it is difficult to link the fan and the opening / closing door 904, and the degree of freedom in designing a building is also restricted.

In view of the above situation, the present invention provides a compact heat-insulating and air-tight structure that can perform ventilation of a building in a heat-insulating and air-tight manner without the necessity of providing a garbage or a dormer even in a gable or a ridge type. It is intended to provide a type ventilation device.
