Description

  The present invention relates to an air purification device that purifies, deodorizes, and sterilizes air, and more particularly, to an air purification device that can efficiently process tobacco smoke and tobacco odor in a game arcade such as a pachinko parlor.

  In game halls where game machines such as pachinko machines and slot machines are installed, the people who smoke often smoking while playing for a long time, so the room is always filled with tobacco odor and tobacco smoke. Yes. This cigarette smoke is not desirable from the health and environmental viewpoints, not only for those who do not smoke, but also for people who smoke, so the amusement hall is required to purify the air at all times. Yes.

  Therefore, it is a common practice to arrange a duct on the indoor ceiling or the like, take in indoor air from here, and perform air purification in a centralized manner using an air purification device installed separately. However, in this centralized air purification system, even if it is a device with a fairly powerful capacity, the smoke of the smoker smokes until it reaches the air intake such as the ceiling. The air purification effect becomes lower as the indoor space becomes wider.

Therefore, it has been devised to arrange a compact air purification device for each unit at the top of the game table, and according to this, the smoke of cigarettes produced by smoking by the game person sitting in front of the game table, It is taken into the air purifier at the top of the game table and deodorized and purified, and as a result, clean air is blown out.

However, even with the above-described conventional air purification device installed for each game stand, the influence of cigarette smoke on the game player could not be completely eliminated. In other words, the cigarettes held by the players are often located in the ashtray located at the lower part of the game table. The cigarette smoke at the lower part of the game table is sent to the air purifier at the upper part of the game table. An air flow having a flow velocity large enough to be sucked in in a short time could not be generated by a compact air purifier installed at each game stand. In addition, with only the filter and the electrostatic air cleaning device in the conventional air purification device described above, although dust can be removed to some extent, gas components such as tobacco odor cannot be removed. It was.
Also, the positively charged dust floating in the amusement hall was adsorbed on the game table and other devices and was contaminated.
Furthermore, the air purifier that is always in operation needs to clean the filter frequently because it absorbs a large amount of dust, and it is necessary to replace the parts regularly. Since the number of air purifiers is large, it takes a lot of work and time to remove the air purifier.

It consists of photocatalytic means for decomposing, negative ion generating means for discharging positively charged dust by discharging negative ions to prevent dust from adhering to the game stand, etc., and an exhaust part for exhausting purified air It is characterized by that.

  In addition, the air flow cross-sectional area is made smaller than the cross-sectional area of the air flow path of the prefilter part in order to collect and suck up the rising tobacco smoke more quickly in all or part of the intake flow path of the intake part. It is characterized in that an intake flow path portion is formed.

  In addition, an openable / closable lid is provided on the front surface to facilitate replacement and maintenance of the prefilter, the multifunction filter, and the photocatalyst means.

  In addition, the intake flow path portion of the intake portion is formed with a wide opening portion having an opening area that increases toward the intake opening at the tip of the opening, thereby preventing turbulent flow of the intake air.

  In addition, the air intake section projects from the air purifier main body toward the bottom of the game machine.

  The air purifying apparatus of the present invention is installed at the upper part of a game machine such as a pachinko machine or a slot machine, and is provided with an intake part for sucking cigarette smoke and the like, and a relatively large air in the intake air provided at the rear stage of the intake part. Pre-filter for adsorbing dust, multi-function filter disposed downstream of the pre-filter for dedusting and adsorbing deodorization, photocatalyst means disposed downstream of the multi-function filter for decomposing gaseous components in the air and negative ions It consists of negative ion generation means that discharges dust that is positively charged by discharging the dust and suppresses dust from adhering to the game table, etc., and an exhaust part that exhausts the purified air. Suitable for removing and purifying various dust and odorous gas components contained in cigarette smoke, etc. in amusement halls, and removing the negatively charged dust that is positively charged to suppress adsorption to game machines Make the environment One in which it is bet.

  In addition, the air flow cross-sectional area is made smaller than the cross-sectional area of the air flow path of the prefilter part in order to collect and suck up the rising tobacco smoke more quickly in all or part of the intake flow path of the intake part. By forming the intake flow path section, the air flow narrowed in the intake flow path section has a higher flow velocity, and the tobacco smoke rising by this fast air flow can be quickly taken in from the intake section and purified Is possible.

  In addition, a cover that can be opened and closed is provided on the front surface, and the pre-filter, multifunction filter, and photocatalyst means can be easily replaced and maintained, so that the filter can be easily cleaned, maintained, and replaced. .

  In addition, the intake passage section of the intake section is formed with a wide opening portion that expands the opening area toward the intake opening at the tip of the opening to prevent the turbulent flow of the intake air, thereby preventing It is possible to obtain a smooth laminar flow without causing the air to be taken in more quickly.

  Further, the intake portion projects from the air purifier main body toward the lower side of the game table, so that the smoke of tobacco rising from the lower side of the game table can be quickly and suitably collected.

  1 to 5 show an air purification apparatus 1 according to the present invention, in which 2 is a front panel, 3 is a first lid at the center of the salt surface panel 2, and 4 is a second lid at the left end of the front panel 2. , 5 is a slit-like air intake portion formed at the lower part of the front panel 2 with a width close to the entire width, and 6 is for removing relatively large dust through which air taken in from the air intake portion 5 first passes. A pre-filter, 7 is a multi-function filter having a dust removing / deodorizing action, which is provided at the subsequent stage of the pre-filter 6, 8 is a blower fan, and 9 is a photocatalyst for decomposing tobacco odor gas components such as acetaldehyde. A photocatalyst member 12 comprising a photocatalyst plate 10 disposed on parallel plates facing each other and an ultraviolet lamp 11 for exciting the photocatalyst, 12 is a negative ion generating member provided with a needle-like discharge electrode 13 toward the outside. Reference numeral 14 denotes a control unit that drives and controls the air cleaning device 1. Reference numeral 15 denotes an exhaust unit that exhausts the purified air.

  The pre-filter 6 is a synthetic resin filter formed in a coarse mesh shape, and adsorbs relatively large dust. In order to prevent clogging, for example, daily cleaning is desired.

  The multi-function filter 7 is disposed in the subsequent stage of the pre-filter 6 and forms a felt-like filter knitted finer than the pre-filter 6 into a pleat shape or a bellows shape to increase the surface area, thereby increasing the surface area. In addition to being able to adsorb a smaller amount of dust without clogging, it has a structure in which tobacco odors such as ammonia and acetic acid are physically adsorbed by built-in porous activated carbon. Further, although not as frequently as the prefilter 6, it is necessary to periodically clean in order to prevent clogging, and when the amount of adsorption becomes saturated, it is necessary to replace it with a new one as appropriate.

  The blower fan 8 is disposed downstream of the multi-function filter 7, and as shown in FIG. 2, a sirocco fan having a high static pressure and a large air flow is disposed at the lower right of the air purifying device 1, and has a two-stage structure. The air from the upper stage of the case body 16 is taken in and blown toward the center of the lower stage.

  The photocatalyst member 9 is formed by crystallizing titanium oxide as a photocatalyst into a prismatic shape on opposite surfaces of the photocatalyst plate 10 that is positioned in the direction in which the blower fan 8 sends out air and that is arranged vertically. An ultraviolet lamp 11 for photocatalyst excitation is disposed in the air, and the air purified by the multifunction filter 7 is circulated in this space. This photocatalyst member 9 is different from the structure in which a binder is kneaded and applied to titanium oxide as in the conventional photocatalyst, and is made entirely of titanium oxide because it is formed by crystallization, and the surface thereof has prismatic irregularities. Therefore, the surface area is increased, and the photocatalytic effect of gas components such as acetaldehyde decomposition characteristics and formaldehyde decomposition performance is extremely high.

  The negative ion generating member 12 projects a needle-like discharge electrode 13 that generates negative ions by electron emission when a negative high voltage generated by a piezoelectric transformer type high-voltage circuit is applied, and projects outward from the center of the exhaust portion to thereby form a photocatalyst. The negative ions are released into the air by being put on the air purified by the member 9 and sent out from the exhaust section. By discharging negative ions in a large amount, it is possible to suppress the dust charged to a positive charge from being removed and adsorbed to a game machine or other devices, and a clean environment can be maintained.

Provided. Further, by forming the wide opening portion 23 with the opening area increased from the narrow opening portion 21 toward the intake opening 22 at the opening end, smooth laminar flow can be achieved without causing turbulent flow at the intake opening. Thereby, air can be taken in from the intake part 5 more quickly. In the present embodiment, the narrow mouth portion 21 in which the intake passage is narrowed is formed in part, but the present invention is not limited to this, and the air flow cross-sectional area of the entire intake passage may be reduced. Is.

  The first lid 3 of the front panel 2 is for taking out the pre-filter 6 and the multi-function filter 7, and is frequently used for opening and closing for cleaning the pre-filter 6. The second lid portion 4 is opened and closed during maintenance and inspection of the photocatalytic member 9 and periodic replacement of the ultraviolet lamp 11.

  FIG. 6 shows another embodiment of the air purifying apparatus of the present invention, in which the air intake part 24 of the air purifying apparatus 1 is projected below the front panel 25. Thus, smoke 19 of rising cigarette 18 can be suitably collected by making air intake part 24 face down.
