However, according to the above-mentioned conventional building intake / exhaust structure, there are the following problems. For example, in summer, the temperature of the air stagnating in the ceiling of the building often reaches 40 ° C. or higher, and efficient exhaust of the building is required. However, when exhausting with a roof fan, the capacity of the roof fan affects the exhaust efficiency.If the capacity is small, sufficient exhaust cannot be performed, and if a roof fan with a large capacity is installed, Although the exhaust efficiency is improved, the initial cost and the running cost of the facility are required, which is uneconomical. On the other hand, it is possible to provide a large monitor without using a roof fan, but in this case, it is difficult to secure the monitor part itself due to restrictions on the height of the building, etc. Inconveniences such as damage occur. Conventionally, the outside air is sucked in through the opening provided in the lower part of the building along with the above-mentioned exhaust, but the noise of the suction at that time is large, and it is necessary to improve the working environment in the building. In addition, the opening is often provided on the wall surface of the building, and the operating noise of various devices in the building leaks to the outside of the building, possibly damaging the environment in the surrounding area.

(Structure 1) As described in claim 1, the characteristic structure of the present invention for achieving this object is to provide an upper communication portion for connecting and connecting the upper space of the building and the inner space of the outer cylinder, A lower communication portion is provided to connect and connect the lower space of the building and the inner space of the outer cylinder, and a lower portion of the outer cylinder,
An opening for communicating the inside of the outer cylinder with the outside air is provided, and a partition wall that vertically partitions a space between the outer cylinder and the inner cylinder is below the upper communication section, It is configured to be provided above the lower communication portion and the opening. (Operation / Effect) According to the building intake / exhaust structure of the present invention, since the upper space of the building communicates with the outside air through the upper communication part and the inner space of the outer cylinder, the natural air flow of the chimney By virtue of exhaust power, the exhaust efficiency at the time of discharging high-temperature air to the outside is improved. The natural ventilation increases as the temperature of the exhausted building air increases and as the height of the chimney increases. According to this configuration, it is possible to efficiently exhaust the high-temperature building air stagnated in the upper part of the building without using a special exhaust device such as a motor fan. Further, in the building intake / exhaust structure, when discharging the high-temperature air, an opening for sucking outside air is provided below the outer cylinder of the chimney provided independently of the building. The outside air is naturally sucked into the building via the communication part. For this reason, noise when inhaling outside air is reduced in the lower communication portion, and it is possible to effectively prevent intrusion into the building, so that the working environment in the building can be improved. On the other hand, according to the above configuration, since the operating sounds of the various devices generated in the building do not leak to the outside of the building, there is no risk of damaging the environment around the building. Further, by providing the partition wall, the inconvenience that the high-temperature air discharged from the upper communication portion is guided again into the building via the lower communication portion is eliminated, and the effect of the exhaust is ensured. Can be something. In addition, the following effects can be expected. That is, since it is not necessary to provide a motor fan or a monitor in the upper part of the building, the cost for installing the motor fan and the running cost of the equipment are not required, which is economically advantageous. Further, even when the height of the building is restricted by height restrictions or the like, the space inside the building can be effectively used if a space for providing a motor fan or a monitor becomes unnecessary. It does not impair the design of the exterior view. Further, as another effect, exhausting the high-temperature air in the building through the outer cylinder of the chimney is a general combustion exhaust gas exhausted through an inner cylinder provided inside the outer cylinder. Can be expected to have the effect of keeping the temperature of the exhaust gas, which contributes to the prevention of white smoke when the combustion exhaust gas is released to the outside air.

In the building intake / exhaust structure of the present invention, the chimney 3
The high-temperature air is exhausted through the air outlet, so that the natural exhaustion of the chimney 3 allows efficient exhaust.
This natural ventilation force increases as the temperature of the discharged gas is higher and the height of the outer cylinder 7 is higher. That is, the exhaust efficiency increases as the difference between the air pressure in the internal space of the building 1 and the air pressure at the tip of the chimney 3 increases. Further, the outer cylinder 7
The exhaust capacity increases as the cross-sectional area of the space sandwiched between the inner cylinder 8 and the inner cylinder 8 increases. Therefore, in order to obtain the best exhaust efficiency, the chimney 3 may be appropriately designed according to the assumed maximum indoor temperature of the building 1 or the capacity of the indoor space. By utilizing the natural ventilation power of the chimney 3, it is possible to efficiently inhale the external cold air efficiently in the lower part of the building 1. Furthermore, if the outer cylinder 7 is vertically divided as shown in FIG. 1, the intake and exhaust between the inside and the outside of the building 1 can be reliably distinguished, and the intake and exhaust efficiency can be further improved. Specifically, the partition wall 10 is used to divide the space between the outer cylinder 7 and the inner cylinder 8 below the upper communication section 4 and the lower communication section 5 and the opening. 6, a passage from the upper space of the building 1 to the outside via the upper communication part 4 and the outer cylinder 7, and the building from the opening 6 via the lower communication part 5. Thus, the passage leading to the lower space 1 is configured independently. That is, when the outside air is naturally sucked into the building 1, the inconvenience that the high-temperature air discharged from the upper communication portion 4 is guided again to the inside of the building 1 via the lower communication portion 5 is solved. Done,
The effect of intake and exhaust can be ensured.

In the present invention, as described above, since the opening 6 for sucking outside air and the building 1 are provided apart from each other, the following effects can be expected. That is, the suction sound generated when the outside air is sucked in the opening 6 is silenced in the lower communication portion 5 and is not transmitted to the building 1. Therefore, the noise level in the building 1 can be kept low as compared with the related art in which the outside air suction unit is provided below the wall of the building 1. On the other hand, the operating noise of the combustion device 2 or other devices generated inside the building 1 is also silenced in the lower communication portion 5, so that it may leak from the opening 6 to the vicinity of the building 1. Absent. Therefore, there is no risk of deteriorating the noise environment in the surrounding area.

In addition, the building intake / exhaust structure of the present invention has the following effects. Paying attention to the inner cylinder 8,
The high-temperature air of the building 1 discharged through the periphery of the inner cylinder 8 heats the inner cylinder 8, and as a result,
The combustion exhaust gas flowing inside the inner cylinder 8 is kept warm,
This will help to prevent white smoke when the combustion exhaust gas is released to the outside air. Further, when the high-temperature air of the building 1 is discharged, the natural ventilation of the chimney 3 is used, so that a space for providing a motor fan or a monitor is unnecessary, and the height of the building 1 is temporarily increased. Even when the space is regulated by restrictions or the like, the space in the building 1 can be used effectively. The design of the exterior of the building 1 is not impaired.
