DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air purifier for a pachinko game machine, and more particularly, to an air purifier installed in a pachinko hall at an upper portion of an installation frame where a pachinko game machine is installed, for example, for smoking cigarettes or dust. TECHNICAL FIELD The present invention relates to an air purifier that absorbs contaminated air in a hall containing, and discharges the air as deodorized and smoke-free clean air.

[0002]

2. Description of the Related Art In recent years, pachinko games using "pachinko gaming machines" such as pachinko machines and slot machines have become extremely popular. For example, in a pachinko game using a pachinko machine, the pachinko ball can be fired and a predetermined game can be played by a simple operation in which a player sits on the front side of the game machine and turns the handle with his right hand. Such a pachinko game often has a playing time ranging from tens of minutes to several hours, and is represented as a so-called “time-consuming leisure”. Therefore, the pachinko gaming machine is provided with an ashtray so that smokers can play the game while smoking. However, in a general pachinko hall, 200 to 500 or more pachinko game machines are installed, and when a large number of players smoke simultaneously, a large amount of smoke is generated. In addition, since dust and the like are also generated by the operation of the pachinko gaming machine and various attached devices, the air in the hall is extremely easily polluted. Therefore, in recent pachinko halls, a large-scale ventilation system equipped with the latest air purifiers and air conditioners has been installed, and a small air purifier has been installed on the installation frame where pachinko game machines have been installed. We are trying to improve the environment inside.

[0003] For example, FIG. 10 shows an air installed at predetermined intervals above an installation frame 51 called an “island” on which a pachinko machine 50 is installed, and used together with an existing ventilation system to purify air in the hall. This is an example of a purifier, and the air purifier 60 is configured as shown in FIG. That is, by the rotation of the internal fan 61, the contaminated air is sucked into the air cleaner 60 from the front slit 62 a, and relatively large dust and the like are first collected by the pre-filter 63. next,
When the contaminated air passes through the discharge unit 64, the fine particles of odor and smoke contained in the air are charged with positive electricity, and the contaminated air is supplied to the negative electrode plate of the dust collection electrode in the dust collection unit 65 disposed on the downstream side. Adsorb. Then, deodorization and sterilization are performed in the photocatalyst filters 66 and 66 and the ultraviolet lamp unit 67, and deodorization is performed by the after filter 68, so that the rear slit 62b of the air purifier 60 as deodorized and smoke-removed clean air. It is designed to be discharged from.

FIG. 12 shows a smoke sending system 70 installed above the front of the installation frame 51. The smoke sending system 70 is, as shown in FIG. Smoke pipe 71 extending substantially horizontally to curtain plate 51a
And a fan 72 provided inside the smoke pipe 71. A plurality of slits 71a are formed in the lower surface of the smoke pipe 71 in the longitudinal direction, and an outlet 73 is formed in a portion located below a ventilation system 75 installed in a ceiling portion of the hall. I have. Accordingly, the contaminated air in the vicinity of each pachinko machine 50 is sucked into the smoke pipe 71 through each slit 71a under the rotation of the fan 72, and after moving inside the smoke pipe 71 to the left in the drawing, the outlet It is discharged from 73 toward the suction port of the ventilation system 75. After the contaminated air is purified by the ventilation system 75, the contaminated air is discharged again as clean air into the hall.
That is, the smoke sending system 70 is for guiding the contaminated air near the installation frame 51 to the existing ventilation system 75 installed in the hall, and has a function of purifying the contaminated air itself. I haven't.

[0005]

The air purifier 60 shown in FIGS. 10 and 11 employs the latest mechanism such as a photo-excited catalyzer, so that it is possible to purify contaminated air in the hall. That is, dust collection, deodorization, sterilization, and the like can be efficiently performed. However, this air purifier 6
0 is intended for auxiliary use of the existing ventilation system installed in the hall, but the discharge unit 64
And the dust collecting unit 65, the photocatalyst filter 66, the ultraviolet lamp unit 67, and the like, there is a disadvantage that the manufacturing cost increases and the device itself becomes expensive.
The pre-filter 63, the discharge unit 64, the dust collection unit 65, and the like require regular cleaning, and the photocatalyst filter 66, the ultraviolet lamp 67, and the after filter 68
And the like must be replaced periodically, and there is also a drawback that maintenance costs are increased. Further, the fan 72
In addition to the electric power for driving the power supply, the electric power of the discharge unit 64, the dust collection unit 65, the ultraviolet lamp 67, and the like is separately required, and it is pointed out that the running cost is increased.

On the other hand, in the smoke sending system 70 shown in FIGS. 12 and 13, it is possible to improve the cleaning efficiency of the existing ventilation system 75 installed in the hall, and to guide the polluted air to the ventilation system 75. Since it can be constituted only by the smoke tube 71 and the fan 72, there is an advantage that the device itself can be manufactured at low cost. However, since the smoke pipe 71 needs to be installed over the entire length between both ends of the installation frame 51, the apparatus itself becomes large, and the fan 72 is enlarged in order to efficiently suck the contaminated air from each slit 71a. Or multiple units must be installed. Therefore, the suction sound of the contaminated air flowing from the slit 71a and the discharge sound of the contaminated air from the air outlet 73 increase unpleasantly, and the fan 72 drives the smoke pipe 71, the installation frame 51, and the pachinko machine 5.
There is a disadvantage that a new adverse effect that vibration occurs at 0 or the like occurs. Therefore, from the viewpoint of improving the overall environment in the hall including the noise problem, there remains a major problem.

[0007]

SUMMARY OF THE INVENTION The present invention has been newly proposed in order to solve the above-mentioned problems, and has a small size and light weight so that it can be operated with low noise and low vibration. It is an object of the present invention to provide an air purifier for a pachinko gaming machine which can simplify such a mechanism and configuration to reduce maintenance costs and maintenance costs.

[0008]

[Means for solving the problems] To overcome the above-mentioned problems,
In order to achieve the intended purpose, the air purifier for a pachinko gaming machine according to the present invention is mounted above a pachinko gaming machine installed on an installation frame in a pachinko hall, and is a hall containing tobacco smoke and dust.
