Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a building capable of natural ventilation.

[0002]

BACKGROUND ART In recent years, with the development of air conditioning equipment, air conditioning equipment has been used to perform cooling and heating. Therefore, in buildings such as houses, in order to improve the air conditioning effect, in order to reduce the energy loss in the air conditioning inside the building, to block the air in and out of the room, to prevent the heat in the room from leaking outside. , A highly airtight and highly insulated building with high indoor airtightness and heat insulation is used.

In such a highly airtight and highly heat-insulating building, since the entrance and exit of air inside and outside is blocked, it is necessary to sufficiently ventilate the building. Therefore, in order to ventilate a highly airtight and highly heat-insulated building, a central ventilation device that collectively ventilates a plurality of partitioned spaces such as living rooms in the building is used (see JP-A-11-344253). ). However, using such a ventilator requires a high cost to install the ventilator and consumes a lot of energy. Therefore, especially in summer, it is desired to perform natural ventilation without using the ventilator. By the way, conventional natural ventilation opens the windows and doors of each room to introduce outside air into the building,
It was performed by replacing the air inside the building.

[0004]

However, there is a problem that warm air is collected near the ceiling of each room only by opening the window or door of each room. In addition, it is difficult to improve ventilation efficiency because windows and doors are not always provided facing the direction in which the wind blows.

An object of the present invention is to provide a building capable of efficiently performing natural ventilation.

[0006]

Therefore, the present invention aims to achieve the above object by adopting the following constitution. The invention according to claim 1 is an inflow port 150A, 170A, 150B, 170B, 270 for taking in outside air into the room.
In the building 1 in which A and 300A are formed, the passage through which the outside air taken in from the inlet passes through a plurality of rooms, and a part of the ceiling in the passage is higher than the ceiling of other portions of the passage. Ventilation ceilings 135 and 255 that project upward and have a high ceiling position, and an exhaust port 2 that discharges air that has flowed in from the inflow port and that has accumulated on the ventilation ceiling.
50B and 252, and the inflow port is provided so as to face the direction in which the wind blows most frequently in a predetermined season.

Here, the inflow port means an opening provided in a room or the like facing the outside and capable of directly taking in outside air, and is usually constituted by a window or a door provided on an outer wall of a building. The exhaust port may be an opening such as a window that directly discharges the air accumulated on the ventilation ceiling to the outside, or an opening for discharging the air to a non-living room space such as an attic. The air discharged from the latter opening is discharged outside through the non-living room space. In addition, providing the inlet facing the direction in which the wind blows most often means not only when the inlet is provided on the surface orthogonal to the direction in which the wind blows, but also when the wind blows toward the corner of the building. It means that an inflow port is provided on one or both of the two surfaces forming the corner.

According to the invention of this structure, since the building is provided with an inlet and an exhaust port for taking in outside air, the outside air passes through the inside of the building, and natural ventilation is performed inside the building without using a ventilation device. It is possible to save energy. In addition, a part of the ceiling in the passage through which the outside air passes has a ventilation ceiling whose ceiling position is higher than the ceilings of other parts.Therefore, the air accumulated near the ventilation ceiling is also exhausted from the exhaust port. can do. Therefore, the flow of air inside the building is improved, and natural ventilation can be performed more efficiently. In addition, warm air does not collect in the living space below the ventilation ceiling, so that the living space can be made comfortable. Further, since the inflow port is provided facing a direction in which the wind is most frequently blown in a predetermined season, for example, summer, the outside air can be efficiently taken into the building. Also, since the outside air passage is formed through multiple rooms, even if there is a room where it is difficult to take in the outside air, it is possible to ventilate the room by forming the outside air passage through the room. .

According to a second aspect of the invention, in the building according to the first aspect, the vertical axis rotating windows 150A, 17 are provided at the inlet.

Is provided in the lower part of the outer wall of the rooms 15 and 17 provided facing the direction in which the wind blows most frequently in a predetermined season, and the outside air introduced from the inlet is discharged from the vicinity of the ceiling of the room. It is characterized by being flowed to another room. Since the inflow port is formed in the lower part of the outer wall of the room, outside air can be taken in from below the room and discharged from the vicinity of the ceiling. Therefore, the entire room can be ventilated by the upward flow.

The invention according to claim 4 is the building according to any one of claims 1 to 3, characterized in that the height of the ventilation ceiling from the floor is higher than the height of the occupant. To do. If the ventilation ceiling is formed at a position higher than the height of the occupant, the occupant does not feel the warm air collected in the ventilation ceiling, and the living space can be made comfortable.

According to a fifth aspect of the present invention, in the building according to any one of the first to fourth aspects, the room 25 provided with the ventilation ceiling is lower than the ventilation ceiling 255 and the ventilation ceiling. And a beam 9 is provided below the ventilation ceiling of the wall supporting the ventilation ceiling and below the height of the ceiling. . By providing a beam on the wall that supports the ventilation ceiling, it is possible to increase the support strength of the ventilation ceiling. Further, the height of the ceiling formed at a position lower than the ventilation ceiling of the room provided with the ventilation ceiling is lowered, and when this room is made into a warehouse or the like, the lower part of the ceiling is not treated as a living room, Not included in the floor area of the building. However, since the ceiling height of the ventilation ceiling is high, the area below the ventilation ceiling may be treated as a normal living room and included in the floor area. On the other hand, in the present application, a beam is provided below the ventilation ceiling, and the ceiling height is calculated based on the height of this beam. Will not be included in. Therefore, the building can be constructed by making the most of the determined volume ratio.

Further, by adjusting the position where the beam 9 is arranged to the height of the ceiling of the warehouse 25 other than the ventilation ceiling 255, the appearance can be made good. Furthermore, since the ceiling height of the ventilation ceiling 255 is as high as about 190 cm, it is usually
This part is treated as a living room, not as a warehouse, and is included in the floor area. On the other hand, in this embodiment, the beam 9 is provided below the ventilation ceiling 255, and the ceiling height is calculated based on this beam 9, so the height of the beam 9 from the floor surface is 140 cm. Below is not included in the floor area. Therefore, the building 1 can be configured by maximizing the determined volume ratio.

Since the exhaust port provided in the living room 13 on the first floor is the window 250B provided on the wall on the second floor to which the balcony 24B is attached, the main bedroom 2
The window 250B can be opened and closed from 0 to the balcony 24B, and no special opening / closing means is required.
