Description

  The present invention relates to a ventilation system in a hall.

  Due to increasing interest in people's health and the enforcement of the Health Promotion Act, smoking countermeasures have become widespread in places where many people gather, such as workplaces, restaurants, and public facilities.

  Such measures include, for example, separating the seats of smokers and non-smokers, or providing a smoking room equipped with an air purifier or ventilation device in a room physically separated from the outside by walls or the like. Yes. As for the former, since each area is not physically separated, there is a problem that smoke and harmful substances flow and the smoke does not inhale, and that smoke or the like adheres to hair and clothes. The latter is effective in that it is completely smoked for non-smokers.

By the way, in amusement halls such as pachinko machines, cigarette smoke often spreads throughout the hall, and many players have been required to purify the air inside the hall. Therefore, smoking countermeasures are also being implemented at amusement halls.
Many amusement halls that take measures against smoking employ measures to separate the seats of smokers and non-smokers. However, as described above, a substantial smoke separation effect cannot be obtained, which is not an effective measure. Recently, a thin air cleaner installed between an amusement stand and an amusement stand has come to be used. However, the purification effect is insufficient, and there is also a problem that the player's body gets cold.
On the other hand, it is difficult to physically cover a game space such as an island facility with a wall or the like because of the structure of the game hall. In addition, even if a separate smoking room is provided, it is very troublesome for smokers to move between the playground and the smoking room.

  As described above, at the present stage, there is no method or method for effectively ventilating or purifying the air in the hall while the player plays without inconvenience in the amusement hall.

  Therefore, the present invention has been made to solve the above-mentioned problems, and the air in the hall can be reliably ventilated in a short time, and a comfortable space can be formed by filling the hall with aroma. The aim is to provide a ventilation system.

As a means for solving the above-mentioned problem, the in-house ventilation system according to claim 1 is composed of a blower installed at a high place and a ventilator installed on a wall surface in the blowing direction of the blower. It is characterized by ventilating by circulating a large scale.
According to this, the air in the hall is circulated on a large scale while the air in the hall is sent to the ventilator side by the blower, and the air in the hall is exhausted by the ventilator.

Further, the air blowing device may be provided with an aroma generating device so as to blow an aroma component at the time of air blowing.
Here, the fragrance component means a fragrance component used in aromatherapy (hereinafter referred to as an aroma component), a fragrance used in perfume, and the like.

  Furthermore, a control device can be provided to the blower device, the ventilation device, and the fragrance generating device to control them. This makes it possible to automate the commands given to each device, and when using a plurality of each device, it is possible to control each device in synchronization.

  In addition, when the air in the hall becomes dirty, the control device starts blowing the strong air at the same time as the ventilator starts moving, and then the air speed blown out from the air blower becomes weak when the air in the hall is cleaned. At the same time the switch is made, the ventilator stops and the fragrance generator operates, and then repeats the control procedure in which the blower and the fragrance generator stop when the fragrance component fills the building due to the weak wind of the blower It can be performed.

  According to the present invention, dirty air is efficiently exhausted outside the hall while circulating the air in the hall on a large scale, so that the air in the hall can be reliably ventilated in a short time. Moreover, even if pachinko island facilities are installed in the building or partitioned, the air in the shielding area is circulated even if there is something in the building that shields the flow of air. It can be ventilated reliably.

Moreover, a fragrance component is ventilated with the ventilation of an air blower, a fragrance component can be spread to every corner of a hall, and the hall can be filled with a fragrance ingredient. Therefore, the off-flavor attached to the hair and clothes is reduced and the fragrance is attached, so that the odor attached to the hair and clothes is not a concern.
In addition, when the aromatic component is an aroma component, the scent of the aroma component provides a comfortable space in the hall, which can provide people with mental effects such as calming people's hearts and releasing stress.

  Furthermore, by controlling each device with the control device and automating the ventilation system, the effort to manage the management system is reduced, and by setting appropriate exercise time and air flow rate etc., ventilation and The fragrance component can be blown, and the cost of the power consumption can be reduced.

  Hereinafter, embodiments of a ventilation system according to the present invention will be described with reference to the drawings. Here, the description will be made based on the application of the present system to a hall 21 of a game hall such as a pachinko or the like that is a large-scale building and the air in the hall 21 is easily contaminated by cigarette smoke or the like and is highly ventilated . FIG. 1 is a perspective view showing an embodiment of a ventilation system according to the present invention. The ventilation system according to the present invention is mainly composed of a blower 1, a ventilator 2, an aroma generator 3, and a control device (not shown).

  First, in the configuration of the ventilation system, various types of devices such as a centrifugal fan, an axial fan, and a diagonal fan can be applied to the blower 1. Above all, multi-blade fans classified as centrifugal fans are easy to use because they are small and lightweight. Regarding the air volume, when the hall 21 is wide, the high-speed rotating blower 1 that can blow strong wind is used, and the air volume is such that the wind is transmitted from the wall of the hall 21 to the facing wall according to the size of the hall 21. Is used. Moreover, if what can set an airflow in multiple steps | paragraphs can be used, power consumption can be suppressed and moreover, effective ventilation can be performed combining the aroma generator 3 mentioned later. Furthermore, if the wind direction control function such as the louver 7 (see FIG. 4) is provided, the air flow in the hall 21 can be adjusted.

About the installation of the air blower 1, it installs so that the wall surface to which the ventilator 2 mentioned later is attached may be opposed. Therefore, it is good to install in an amusement hall with the installation stand directly on the island equipment 4, or on the island equipment 4. Moreover, you may suspend the air blower 1 from a ceiling etc., or you may attach to a wall surface.
Moreover, when the hall 21 is large, a plurality of blowers 1 are used. When a plurality of ventilation devices 2 are attached to one wall, each blower device 1 is installed so as to face the ventilation device 2. In the case of a game hall, the air blowers 1 are installed side by side on the island facility 4 with an appropriate interval.
On the other hand, when the ventilation device 2 is attached to a plurality of walls, the blower device 1 may be installed in a form facing each ventilation device 2.

Next, the ventilation device 2 is of a type that is installed on a wall, and various types of devices such as a centrifugal fan and an axial fan can be applied thereto. Moreover, the ventilation apparatus 2 is an apparatus which can ventilate suitable air volume according to the size of the hall 21 like the air blower 1, and is preferably an apparatus capable of setting the air volume in multiple stages. In addition, when the air volume of the ventilator 2 is greatly reduced due to the influence of a filter or outdoor natural wind, the pressure type ventilator 2 is effective.
The ventilation device 2 is installed on the wall of the blower device 1 on the blowing direction side. The installation height is desirably about the same as the installation height of the blower 1. Moreover, when the hall 21 is large, it is good to install several ventilation apparatus 2 in one or several wall.
Depending on the size of the hall 21 or the specifications and the number of installed blowers 1 and ventilators 2, the air pressure in the hall 21 may drop, causing various obstacles. In this case, it is necessary to take some measures for taking air into the hall 21 such as providing an intake means in the hall 21.

For the aroma generator 3, an aroma diffuser, an aroma humidifier, an electric aroma pod, or the like is used. Here, the aroma diffuser and the aroma humidifier have high performance for diffusing aroma components, and are suitable for use in a large hall. Moreover, if the aroma generator 3 has a component ejection amount setting means, a suitable amount of the aroma component can be released. About an aroma component, it does not specifically limit and a suitable thing can be used. In addition, you may use the apparatus which generate | occur | produces a fragrance | flavor instead of the aroma generator 3. FIG.
As shown in FIG. 2 or 3, the aroma generator 3 is provided on the front surface of the air blowing port 5 or the front surface of the air intake port 6 of the air blowing device 1. By doing in this way, since the generated aroma component is blown or taken in from the intake port 6 and blown, the aroma component can be sent to a point away from the aroma generator 3. In addition, when taking in an aroma component from the inlet port 6, as the air blower 1, what has an inlet port in the rear surface or the side surface is desirable.
Moreover, as shown in FIG. 4, the aroma generator 3 and the air blower 1 can also be accommodated in the accommodating body 8 provided with opening. The blower 1 is installed so that the blower port 5 faces the opening of the container 8. In this way, it is possible to blow air after the container 8 is filled with the aroma component, and in this case, the aroma component can be strongly blown and diffused in the hall 21 in a short time. .

  The blower 1, the ventilator 2, and the aroma generator 3 described above can be controlled by a control device such as an inverter. Furthermore, it is possible to perform synchronous control between devices or collective control by a control terminal.

Next, the use of the ventilation system according to the present invention will be described based on the case where each device is controlled synchronously and collectively. FIG. 5 represents the control flow of the ventilation system.
First, when the air in the hall 21 is dirty or when the air is ventilated, control of the ventilation system is started.
And as a 1st process, the air blower 1 and the ventilation apparatus 2 are operated, and ventilation and ventilation are performed. At this time, the air volume of each device can be suitably determined, but if the air volume is increased, the air can be ventilated in a short time and the air in the hall can be surely cleaned.
Subsequently, after performing a 1st process for predetermined time (for example, 30 minutes), as a 2nd process, the driving | operation of the ventilation apparatus 2 is stopped, the air volume of the air blower 1 is made into a weak wind, and also the aroma generator 3 is operated. Thereby, an aroma component can be put on a wind and an aroma component can be spread throughout the hall.
Finally, after performing a 2nd process for predetermined time (for example, 30 minutes), the air blower 1 and the aroma generator 3 are stopped.
If necessary, the above-described series of ventilation systems are repeatedly controlled every predetermined time. If not, stop the ventilation system.
Note that the events of each device do not have to be performed simultaneously, and may be performed at different times. Moreover, it may be performed manually regardless of the control device, and when each device is provided with a timer, the above steps may be performed using a timer or the like.

The situation of ventilation and ventilation in the first step is shown in FIGS. Dirty air or the like is carried to the front surface of the ventilator 2 by the air blown by the blower 1, and is discharged to the outside by the ventilator 2. Also, in the hall 21, a planar air circulation flow is formed by ventilation and ventilation, and the air that is not ventilated even if it is carried to the front of the ventilator 2 is again carried to the front of the ventilator 2, and eventually to the outdoors. It is discharged (see FIG. 6). Moreover, even if the island equipment 4 or the like is installed between the blower 1 and the ventilator 2, a cavity flow that circulates in the vertical direction is generated, and the air below the installation position of the blower 1 is also wound upward, It will be carried by the ventilation of the ventilation apparatus 1 and will be carried to the ventilation apparatus 2 front surface.
As described above, according to the ventilation system according to the present invention, the air in the hall 21 can be surely ventilated even in the hall 21 where a large number of island facilities 4 are installed and difficult to ventilate, such as a game hall such as a pachinko parlor. Can do.

  In the second step, the ventilation device 2 is stopped, the aroma generating device 3 is operated, and the generated aroma component is blown by the blower device 1 so that the aroma component reaches every corner of the hall. The fragrance reduces the odor and makes the space 21 comfortable, relieving the player's stress and stabilizing the spirit.

In order to examine the effect of the ventilation system according to the present invention, the ventilation system was installed in a pachinko amusement hall, the first step was performed a plurality of times, and dust floating in the air was measured before and after the step.
Four each of the blower 1 and the ventilator 2 were used. The air blower 1 is installed on a gantry placed on the island facility 4 and arranged on the island facility 4 at an appropriate interval. The ventilation device 2 is attached to the same height as the blower 1 on the blower side wall.
Measurement takes place during actual business hours. After the air in the building 21 is dirty, the dust in the air is measured, the ventilation system is activated from there, and the first step is performed for about 30 minutes. Again, the dust in the air was measured. A light scattering digital dust meter was used for dust measurement. For reference, dust in the air is measured even before opening the store, where the air in the building 21 is almost clean.
FIG. 8 shows the suspended dust mass concentration in the hall measured before and after using this ventilation system. Moreover, what was measured before opening a store is also shown collectively. According to this, the suspended dust mass concentration before using this ventilation system is about 0.74-0.85 mg / m ³ , whereas the suspended dust mass concentration after using this ventilation system is The value is greatly reduced to about 0.33 to 0.35 mg / m ³ and is close to the value before opening. Thus, it was confirmed that the air in the building 21 was greatly improved by using this ventilation system. In addition, the suspended dust mass concentration after using the ventilation system is slightly higher than the value before opening the store, but it is a measurement during business hours, and it is in a situation where tobacco smoke and dust are constantly rising. It is believed that there is.

  The embodiment of the ventilation system according to the present invention has been described above. Note that the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the gist of the present invention. Moreover, about the application place, it can apply not only in a pachinko game hall but in various halls 21.
