Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to a contaminated air mixed with exhaust gas, dust and the like while taking in external air in a parking lot provided in a building or in the basement of the building. It relates to a parking lot ventilation system configured to forcibly discharge and ventilate.

<Prior Art> As a conventional parking lot ventilation system, a so-called “delivery system” is known, and is configured as follows.

FIG. 4 is a plan view of the above conventional delivent system,
FIG. 5 is a partially cutaway side view of the same, showing an outside air intake portion 01 at a predetermined location of a parking lot provided in the basement of the building, etc.
And an exhaust port 02 for discharging polluted air mixed with exhaust gas and dust.

The intake section 01 has an air supply passage 04 with a blower fan 03 interposed.
Is connected to the exhaust port 02, and an exhaust path 06 having an exhaust fan 05 is connected to the exhaust port 02.

In the parking lot, partition walls 08 are provided at predetermined intervals along the peripheral wall 07, and between the adjacent partition walls 08 and 08, and between the partition wall 08 and the peripheral wall 07 facing it, for example, A parking zone A for parking a predetermined number of cars, such as every three cars, is formed.

Each parking zone A ... An air supply section 09 is formed in the vicinity of each ceiling wall. Further, an auxiliary intake fan 010 for sucking the external air sent by the blower fan 03 is provided at a predetermined position of the ceiling wall part, and the auxiliary intake fan 010 and the air supply part 09 ... Ventilate each. It is connected to each other through the road 011 and blows external air to each of the parking zones A ... through the air supply unit 09 ..., so that polluted air mixed with exhaust gas and dust does not stay in each parking zone A ... It is configured to send out from the intake portion 01 to the air outlet side to the air flow path side formed along the road, and to exhaust the exhaust gas and dust satisfactorily.

<Problems to be Solved by the Invention> However, according to such a conventional system, contaminated air is agitated and flowed from the parking zone A ... There is a disadvantage in that people and parking staff inhale polluted air, which is unfavorable for hygiene.

The present invention has been made in view of such circumstances, and enables the contaminated air to be discharged without stirring so that the user and the parking staff are not adversely affected by the contaminated air. The purpose is to ventilate.

<Means for Solving the Problem> In order to achieve such an object, the parking lot ventilation system of the present invention is provided with an exhaust port on the floor of a parking zone of a parking lot provided with an intake portion for external air, and An air passage provided under the floor of the parking zone is connected to the exhaust port, and a forced exhaust device is connected to the air passage.

<Operation> According to the above configuration, exhaust gas and scattered dust discharged in each parking zone are discharged from the exhaust port provided on the floor of each parking zone through the ventilation passage as the forced exhaust device operates. be able to.

<Example> Hereinafter, an example of the present invention is described in detail based on a drawing.

FIG. 1 is a partially cutaway front view showing an embodiment of a parking lot ventilation system according to the present invention, FIG. 2 is a partially cutaway side view of FIG. 1, and FIG. 3 is a plan view.

In these figures, 1 is an intake part for external air, and 2 is
Indicate first exhaust ports for discharging polluted air mixed with exhaust gas, dust, etc., each of which is provided at a predetermined location of a parking lot provided in the basement of the building or the like.

The intake section 1 has an air supply passage 4 with a blower fan 3 interposed.
On the other hand, the first exhaust port 2 is connected to an exhaust passage 6 in which a first exhaust fan 5 is interposed.

In the parking lot, partition walls 8 are provided along the peripheral wall 7 at predetermined intervals, and the partition walls 8 and 8 are adjacent to each other, and between the partition wall 8 and the peripheral wall 7 opposite thereto, for example, A parking zone A for parking a predetermined number of cars, such as every three cars, is formed.

Each parking zone A ... A second exhaust port 9 is provided on each floor, and a ventilation passage 10 is provided below the floor of the parking zone A ..., and the second exhaust ports 9 ... Respectively communicate with the ventilation passage 10. Has been done.

A second exhaust fan 11 as a forced exhaust device is connected to the ventilation passage 10 so as to communicate polluted air such as exhaust gas and scattered dust generated in each parking zone A and the central road to the floor side. Suction and second exhaust port 9
... and the ventilation path 10 so that it can be discharged.

The air passage 10 is inclined so that it becomes lower on the side of a predetermined location closer to the communication connection location with the second exhaust fan 11,
The drain pipe 12 is connected to the lowest point, and the damper type on-off valve 13 is interposed in the drain pipe 12, and the damper type on-off valve 13 is normally kept in the closed state, and the second type When cleaning the parking lot while exhausting polluted air such as exhaust gas and dust through the exhaust port 9 and the air passage 10, the damper-type on-off valve 13 is opened to remove the second exhaust gas. The mouth 9 and the ventilation passage 10 are used as a drainage passage so that cleaning water can be discharged.

In the case of the above embodiment, for example, 80 to 90% of the amount of air blown by the blower fan 3 is exhausted by the first exhaust fan 5, while 10 to 20% of the amount of air blown is exhausted by the second exhaust fan 11. As described above, it was clear that even if a small amount of air was exhausted through the second exhaust port 9 and the ventilation passage 10, the exhaust gas and dust could be well ventilated without being diffused.

In the present invention, the exhaust amount of the second exhaust fan 11 may be larger than that of the first exhaust fan 5,
Further, the first exhaust port 2, the first exhaust fan 5 and the exhaust passage 6 are not provided respectively, and the total amount is the second exhaust port 9 and the ventilation passage.
It may be configured to exhaust air through the 10 and the second exhaust fan 11.

In this embodiment, the ventilation passage 10 is formed under the floor of the parking zone A, and the ventilation passage 10 is also used as a drainage passage. However, the present invention uses, for example, an existing drainage passage. Alternatively, the ventilation system of the parking lot may be configured by connecting the exhaust fan 11 to the drainage passage.

Further, in the above-mentioned embodiment, each parking zone A is formed by the partition walls 8 ... However, the present invention can be applied to the case where the parking zones A are divided by pillars.

<Advantages of the Invention> According to the parking lot ventilation system of the present invention, since the exhaust port is provided on the floor of each parking zone, exhaust gas generated in each parking zone and scattered dust can be immediately sucked downward and discharged, In addition, a downward suction force can be applied to the exhaust gas and dust on the road, and the exhaust gas and dust do not diffuse and flow in the entire parking lot, which pollutes users and parking staff. You can avoid the negative impact of air,
It became possible to ventilate very hygienely and efficiently.
