Description

Detailed Description of the Invention (Field of Application of the Invention) The present invention relates to a ventilation method mainly used in buildings with high indoor airtightness, such as buildings made of reinforced concrete (RC) or lightweight foamed concrete (ALC). Regarding.

(Prior Art) As mentioned above, as a ventilation method for a highly airtight building, a forced exhaust port consisting of an exhaust fan has been installed in the building frame facing the outside.

This forced exhaust vent is provided in each room or directly in the building frame facing the balcony, while the air supply port is not particularly provided, or a small ventilation window is installed in the building building facing the outdoors. This allows more natural air to be supplied into the room.

In this way, in the past, forced exhaust vents and natural air supply vents were installed directly in the building frame, and naturally these vents had to be installed from the beginning.
It cannot be installed appropriately after construction.

In particular, in the past, as mentioned above, air supply and exhaust vents are installed appropriately in the part of the building that faces the outside, thereby ventilating only a portion of the room and uniformly ventilating each room. If the air pressure in the room becomes negative or positive more than necessary, the exhaust effect from the forced exhaust port or the air supply effect from the natural air supply port may not work properly. Yes, and if you install a forced exhaust port in each room, you will naturally be bothered by the noise from the exhaust fan.

(Problems to be Solved by the Invention) In view of the above-mentioned difficulties, the present invention provides forced exhaust vents and natural air supply vents without directly installing them into the building frame, and also provides air ventilation for each room without being bothered by noise. The purpose of the present invention is to propose a ventilation method for the interior of a building that enables uniform and good ventilation.

(Means for Solving the Problems) In order to solve the above problems, the present invention provides a forced exhaust port in the entrance sash, a natural air supply port in the window sashes other than the entrance sash, and Ventilation holes are provided in the partition walls or sliding screens that separate each room except the bathroom, and outside air is brought into the room from the natural air supply vents, is introduced into each room through the vents, and is then exhausted from the forced exhaust vents. It is characterized in that a certain ventilation flow path is formed inside the room.

(Function) Inside a building, the entrance is generally located far away from the main living space for long periods of time, such as the living room or bedroom. Therefore, even if a forced exhaust vent is installed at the entrance, the noise emitted from the entrance will be transferred to the living room or bedroom. The bulk is attenuated all the way to the main living space, so there is no negative impact on the living environment.

Ventilation holes are provided in partition walls such as partitions or sliding doors that separate each room, and outside air is supplied into the room through the natural air supply openings, is introduced into each room through the ventilation openings, and is then exhausted through the forced exhaust openings. Since a constant ventilation flow path is formed in the room, uniform ventilation is guaranteed in each room due to the outside air constantly flowing through the constant ventilation flow path.

The vents are not provided in at least the opening/closing shoji such as partition walls and doors facing the toilet and bathroom, and do not form part of the ventilation flow path, so odors and the like do not circulate inside the room.

The above-mentioned forced exhaust ports, natural air supply ports, or 'vents' are provided in entrance sashes, window sashes, partition walls such as partitions, or opening/closing shoji such as doors, and are not provided in the building frame.
After construction, they can be installed as appropriate to suit the floor plan.

(Example) FIG. 1 shows an example in which the present invention is embodied in an example of an indoor floor plan of a divided building made of reinforced concrete. First, a forced exhaust port 3 is formed in an entrance sash 2 forming an entrance 1. be done. The detailed structure in which the entrance sash 2 is provided with the forced exhaust port 3 is as shown in Figure 2, Figure 2, and Figure 2C.

That is, by using the sleeve sill 2a of the entrance sash 2, an exhaust duct 4 communicating inside and outside is attached to the upper part of the sleeve sash 2a.
An exhaust fan 5 is provided on the indoor side of the interior, and a fire damper 6 is installed on the outdoor side that melts the sensor 6a due to hot air during a fire and blocks the duct 4 by being biased by a spring 6b. is a slit-shaped opening 4a that also serves as an insect screen.
, 4b.

Referring to Figure 1 again, a natural air supply opening 9 is provided in the window sash 8 facing the veranda 7 of the building or entrance. Specifically, as shown in Figure 3, a sliding door type small ventilation window 9a1 provided at the top of the window sash 8, a ventilation grill 9b as shown in Figure 3C, and a window sash as shown in Figure 3C. The transom ventilation grill 9c provided in the transom part of No. 8, or the third
As shown in the figure, outside air is introduced into the shrine through sleeve ventilation grills 9d provided on both sleeves or one sleeve of the window sash 8.

Furthermore, a ventilation hole 12 penetrating inside and outside is provided in a partition wall such as a partition that partitions each room 10a to 10f such as a living room, a bedroom, a drawing room, a kitchen, and a hallway, and an opening/closing shoji 11 such as a door or a sliding door.

For example, as shown in FIG.
It is preferable to provide a soundproof type ventilation grill 12a on the lower side of the partition wall 11b provided with the above. When the natural air supply port 9 is provided at the top of the window sash 8 as shown in FIG. Outside air circulates over almost the entire area, and no airtightness is formed.

Furthermore, the vent 12 is not provided at least in a partition wall or door that separates the toilet 13 and the bathroom 14, where odor and moisture are generated. Of course, the toilet 13 and bathroom 14 are provided with separate forced ventilation vents (ventilation fans), and each partition wall and door is provided with an intake vent, but this only applies to the toilet 13 or bathroom 14 alone. It is intended to exert a ventilation effect, and the forced exhaust port 3 referred to in the present invention is not provided. Similarly, a range fan is installed in the building frame 16 in the vicinity of the range 15 in the kitchen 10c to release hot air and odors generated by the range into the outside air.
This is also not the forced exhaust port 3 according to the present invention.

The forced exhaust port 3, the natural air supply port 9, and the ventilation port 12 are formed as described above, and the arrangement relationship between these is such that air is supplied into the room from the natural air supply port 9 as shown in FIG. The outside air is
As shown by the arrows, each room 10a~ passes through each ventilation hole 12.
It is necessary to install the ventilation flow passages 17a to 17j to form certain ventilation flow passages 17a to 17j that are exhausted from the forced exhaust port 3 after being introduced into the exhaust gas 10f. - To take an example, the air vent 12 provided in one partition wall 11c of the Japanese-style room 1ob is passed through the Japanese-style room 1ob.
When outside air is introduced into 0b, a ventilation hole 12 must also be provided in the partition wall lid on the other side so that the outside air flows to the forced exhaust port 3 side as shown by an arrow 17f. Conventionally, such considerations were not taken at all.

Therefore, regardless of the season, the outside air is
~17j, each room 10a~10f is constantly ventilated. In principle, the exhaust fan 5 of the forced exhaust port 3 is operated continuously all year round in order to achieve the above-mentioned effect, but the ventilation amount is adjusted by operating it strongly in the summer, weakly in the winter, and strongly when guests come. used.

(Effects) According to the present invention, even in highly airtight rooms such as reinforced concrete buildings, each room is constantly ventilated uniformly and efficiently throughout the year without being affected by noise, creating a comfortable living environment. It is possible to do this without creating.

According to the present invention, since there is no need to provide a ventilation device directly to the building frame, it can be manufactured at relatively low cost.
