Description of the Related Art In a house such as a conventional Japanese house where there are gaps in fittings, and there are gaps around the room, a proper amount of ventilation is naturally provided through these gaps even during heating and cooling. However, in a recent highly airtight house, the gap is reduced and the ventilation is insufficient, which causes problems such as dew condensation on the window glass, air pollution, and oxygen deficiency.

As a means for improving such inconvenience,
For example, as described in JP-A-62-172138, an exhaust port communicating with the outside is provided in the attic, and a ventilation fan and a drive for driving the ventilation fan are provided on the ceiling of the attic. A dedicated forced ventilation device consisting of a motor is installed, and a ventilation opening is provided on the ceiling so that it communicates with the suction port of this forced ventilation device. A structure has been proposed.

[0004]

By the way, in the ventilation structure described in the above publication, as described above, although the exhaust port for discharging the contaminated indoor air to the outside is provided, fresh outside air is not discharged. Since there is no special air supply port for taking in, it is exclusively entrusted to the gap etc., so the ventilation load becomes significantly large, and in order to ventilate each room at the same time, a high output forced ventilation device must be installed. Indispensable. However, the installation of a high-output forced ventilation device is not suitable for general housing because it directly leads to a significant increase in housing equipment cost and thus housing construction cost.

The present invention has been made in view of the above circumstances, and provides a ventilation structure for a house capable of performing appropriate ventilation according to the season for a plurality of rooms or all the rooms in the house at low cost. Is intended.
