Warm air staying at the upper part of air in the room is thereby pushed out and moved downward. Air in the room can thereby be circulated simultaneously with ventilation.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a ventilation structure for a building.

[0002]

2. Description of the Related Art Conventionally, there are various types of heating devices for heating a room in a building, and a heating device for burning kerosene or the like in the room is often used. Further, as a ventilation structure of a building for ventilating a room inside the building, for example, JP-A-63-16
As described in Japanese Patent No. 5632, an air inlet is provided in the underfloor space, an air shaft zone communicates from the underfloor space to the back of the cabin, and an air outlet is provided in the back of the cabin to communicate with the outside. There is known a ventilation structure of a building in which an air inlet and an air outlet which communicate with a room are provided above and below each living room. The ventilation structure of this building ventilates the air in the entire house by air flowing from the underfloor space to the back of the cabin due to the rising force of the air generated by the temperature difference and the wind pressure generated by the wind.

[0003]

However, a heating apparatus that burns kerosene or the like in a room has good thermal efficiency because almost all of the combustion heat of the kerosene is released into the room.
There is a problem that the air in the room is deteriorated by the carbon dioxide gas generated during combustion, and the amount of heat of combustion is reduced because warm air stays at the top of the room and warm air does not come down at the bottom. There is a problem that it does not feel warm compared to it. Therefore, it is necessary to provide ventilation in order to solve the problem that the air in the room deteriorates, and it is necessary to circulate the air in the room to solve the problem that warm air stagnates in the upper part of the room.

In the ventilation structure for a building described in the above-mentioned Japanese Patent Application Laid-Open No. 63-165632, it is difficult to secure a stable and constant ventilation rate because it is greatly affected by the temperature difference inside and outside the building, the wind speed, and the like. . In particular, in a building that is heated with a heating device that burns the kerosene or the like, it is necessary to ventilate a large amount of room air in order to discharge carbon dioxide and the like generated from the heating device from the building. Ventilation by the rising power of air alone is not enough. Therefore, an object of the present invention is to provide a ventilation structure of a building that can circulate room air simultaneously with ventilation.
