Description

  In the present invention where a large number of pachinko machines and the like are lined up, a smoke air curtain that is installed in the upper space between adjacent gaming machines and forms a breeze air curtain between the gaming machines is formed between the gaming machines. The present invention relates to a smoke distribution device that blocks bad odors such as cigarette smoke, alcohol and bad breath.

  Conventionally, the following contaminated air suction cleaning devices have been proposed as air cleaning devices for amusement halls where a large number of pachinko machines and the like are arranged. In other words, the conventional contaminated air suction and cleaning device has a vertically long wind tunnel provided separately from the gaming machine, etc., next to the gaming machine, etc., and from the suction port located beside the gaming machine, etc. by the centrifugal blower inside this wind tunnel. Contaminated air is sucked, ozone gas is generated from an ozone generator provided behind the suction port inside the wind tunnel, the ozone gas and the sucked contaminated air are mixed and discharged upward from the discharge port above the wind tunnel. Thus, contaminated air is cleaned by mixing contaminated air and ozone gas (for example, refer patent document 1).

The following proposals have also been made. That is, silver (Ag) is formed by forming a transparent titanium oxide (TiO ₂ ) thin film having a deodorizing action on the outer surface of the front glass constituting the front portion of the pachinko machine, or by ion sputtering on the outer surface of the front glass. Has been proposed to prevent the smell of cigarettes from adhering to a pachinko machine by utilizing the deodorizing action of titanium oxide (TiO ₂ ) or silver (Ag) (see, for example, Patent Document 2).

JP 2004-125292 A Japanese Patent Laid-Open No. 10-085412

  However, in the conventional contaminated air suction and cleaning device as described above, a large amount of air is released upward from the discharge port at the upper part of the wind tunnel. However, there was a problem that both the noise and power consumption of the device were high. In addition, a vertically long wind tunnel separate from gaming machines, etc. is provided beside a pachinko machine, slot machine, etc., and a suction mechanism using a centrifugal blower is provided inside the wind tunnel, and the odor around the suction port located beside the gaming machine, etc. In order to suck contaminated air, etc., there are restrictions on the space for providing the suction portion, the suction efficiency is low, the apparatus is large, and the structure is complicated.

  On the other hand, with regard to the proposal to prevent the smell of cigarettes from attaching to the pachinko machine using the deodorizing action of titanium oxide or silver, it can be solved to some extent that the smell is attached to the pachinko machine. Smoke, alcohol, bad breath and other bad odors cannot be blocked.

  The present invention has been made to solve such conventional problems, and the problem is to reduce the manufacturing cost by simplifying the configuration of the smoke separation system. It is to obtain a smoke distribution device suitable for low noise and power-saving continuous operation, and to promote improvement in installation workability, usability and performance of the smoke distribution device.

  In order to achieve the above-described problem, a smoke sparing apparatus according to the present invention includes a blower that is provided at an upper boundary between adjacent game machines and blows air downward from a blower outlet, and is vertically moved by the blown air. A smoke distribution device that forms an air curtain extending in the direction of the player and blocks bad odors produced by a player sitting next to the air curtain, and the size of the air curtain formed is set to 0. 0 on a horizontal plane substantially equal to the height of the player's mouth. The horizontal width of the airflow of 3 to 0.6 m / s is about 20 to 30 cm, the front and rear width is 35 cm or more, and the airflow of 0.3 to 0.6 m / s on a horizontal plane substantially equal to the height of the electric handle. The left-right width dimension is about 20 cm, and the front-rear width dimension is 45 cm or more.

  Here, the malodor generated by the player is a malodor such as smoke, alcohol, or bad breath of the player's cigarette.

  According to the present invention, it is possible to reduce the manufacturing cost by simplifying the configuration of the smoke separation method, and it is possible to obtain a smoke separation device suitable for continuous operation with low noise and power saving, and It is possible to promote the improvement of the installation workability of the smoke separator, the improvement of the usability and the improvement of the ability.

  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of a smoke separator according to the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited to the embodiments.

Embodiment 1 FIG.
FIG. 1 is a perspective view of a game arcade where a smoke separation apparatus according to Embodiment 1 of the present invention is installed. In FIG. 1, for example, in a game hall such as a pachinko parlor, a large number of pachinko machines 1 as game machines are installed side by side. The pachinko machine 1 is roughly divided into a main body part 4 covered with a front glass 3 and an operation part 8 provided with an upper ball receiving tray 5, a lower ball receiving tray 6, and an electric handle 7 for driving the ball. It is done.

  A data display 9 is mounted on the data display mounting surface 10 above the front glass 3 of the pachinko machine 1. A maintenance plate 2 is provided further above the data display 9. This maintenance plate 2 is used when maintaining the machinery inside the pachinko machine 1, and opens and closes downward.

  The front glass 3 of the pachinko machine 1 and the mounting surface 10 of the data display device 9 are substantially on the same plane. The smoke separation device 12 of the present embodiment is attached above two adjacent pachinko machines 1 with the air outlets directed downward at a position substantially the same height as the data display device 9.

  A table 11 on which small items can be placed below the pachinko machine 1 is provided. The depth dimension of the table 11 is about 18 cm, and an ashtray is provided on the table 11. In some places, a shelf is provided instead of the table 11. In the smoke separation device 12 of the present embodiment, the distance from the height of the air outlet provided on the lower surface of the main body to the height of the player's mouth is 30 to 50 cm. Similarly, the distance to the height of the table 11 with the ashtray is about 70 cm. Similarly, the distance to the floor is about 160 cm. The left-right width dimension of the pachinko machine 1 is about 50 cm, and the interval between two adjacent pachinko machines is about 20 cm. Thereby, the left-right width dimension of the space occupied by one player is about 70 cm, and the distance between two adjacent people is approximately 25 to 30 cm.

  FIG. 2 is a longitudinal sectional view of the smoke separator 12 as seen from the front side. FIG. 3 is a cross-sectional view of the smoke separator 12 as viewed from the upper surface side. FIG. 4 is a longitudinal sectional view as seen from the right side of the smoke separator 12. FIG. 5 is a perspective view of the smoke separator 12 with the grill provided on the right side open. FIG. 6 is a perspective view seen from the right side of the smoke separator 12 from obliquely below. As shown in FIG. 2, the smoke separator 12 includes a blower 28 that forms a breeze air curtain. The blower 28 is a multi-blade fan blower, and includes a sirocco fan 16, a motor 13 that rotationally drives the sirocco fan 16, and a fan casing 17 that covers the outer periphery of the sirocco fan 16.

  As shown in FIG. 4, the blower 28 is arranged such that the rotation shaft 13 a of the motor 13 extends in the left-right direction when viewed from the front side. The blower 28 is also arranged so that the tongue portion 17a of the fan casing 17 is on the near side (opposite side of the mounting surface 10) and the air outlet 23 is an opening formed on the lower surface of the main body. Regarding the structure of the fan casing 17, the wall surface 17 b on the back side (attachment surface 10 side) of the air outlet 23 is inclined forward by about 10 ° with respect to the attachment surface 10, and four air outlets 23 are provided in the portion of the air outlet 23. The blowout louvers 24 are formed, and each blowout louver 24 is formed so as to increase the angle by 5 ° with respect to the wall surface 17b, that is, 15 °, 20 °, 25 °, and 30 °. The wall surface on the tongue portion 17a side is formed to be inclined by about 35 °. The smoke separator 12 is configured such that the air blown out from the outlet 23 is blown downward diagonally forward instead of directly below.

  As shown in FIGS. 2 and 3, the motor mounting plate 14 b that constitutes the rear side wall surface of the fan casing 17 and fixes the drive motor 13 is disposed substantially perpendicular to the main body 14 and is integrally formed with the main body 14. It is made in. As shown in FIG. 2, when viewed from the front side, body attachment holes 15 are provided in the upper and lower ends of the body 14 on the motor 13 side, and the smoke separator 12 is a drilling screw having a self-tapping function (not shown). Etc. are inserted into the main body mounting hole 15 and fastened to the side of the data display unit 10 of the data display unit 9.

  Here, the arrangement of the fan casing 17 will be described with respect to the case of another form. In FIG. 4, even when the rotation shaft is arranged on the left and right, the front-rear direction is the reverse of FIG. 4, that is, the scroll tongue is positioned on the back side and the outlet surface side is positioned on the front side of the main body. It can also be arranged. However, with such an arrangement, the depth dimension of the main body becomes larger than that of the present embodiment, and a uniform blowing wind speed cannot be obtained even in the wind speed distribution in the front-rear direction. Furthermore, even when the fan suction port side is arranged on the front side and the rotating shaft is arranged in the front-rear direction, a uniform blowing wind speed cannot be obtained in the wind speed distribution in the front-rear direction, and the main body depth dimension is not so thin. There is a suction grille in the front, and it is not a good design. From this, it can be said that the arrangement of the present embodiment is the most excellent.

  Further, in the smoke separator 12 of the first embodiment, the rear side wall surface 17b of the air outlet 23 is inclined about 10 ° forward from the mounting surface 10, and the side wall surface of the tongue portion 17a is inclined about 35 ° forward. However, for example, when the rear side wall surface 17b is inclined about 5 ° forward with respect to the mounting surface 10, and the side wall surface of the tongue portion 17a is arranged about 30 ° forward, it is configured to blow out more directly below or The blower of the present embodiment is modified such that the size of the air outlet 23 is increased in the front-rear direction and the side wall surface of the tongue portion 17a is inclined forward by about 40 ° to increase the front-rear width dimension of the air curtain. This can be done in 28 arrangements.

  As shown in FIGS. 2, 3, and 5, a filter holder 19 for mounting a deodorizing filter 20 is integrally formed in the suction port 18 of the fan casing 17. The filter holder 19 is loaded with a deodorizing filter 20. As shown in FIG. 5, a grille 21 constituting one side surface of the main body case 25 is provided so that a rotation fulcrum extends in the vertical direction on the back surface side of the main body and opens and closes in the front-rear direction. The grill 21 supports the front surface so that the deodorizing filter 20 is securely stored in the filter holder 19 in the closed state. Further, a net-like filter presser 22 is provided in the suction port 18 so that the deodorizing filter 20 is not sucked by the suction of the fan and the administrator does not put a finger or the like into the sirocco fan 16 which is a rotating object during maintenance. 19 is provided.

  The main body case 25 forming the outline of the smoke separator 12 has a box shape covering the blower 28, and the front surface of the main body top surface is greatly rounded, and the maintenance plate 2 positioned above and below is opened and closed. It is designed not to interfere during internal maintenance. In addition, the front side of the lower surface of the main body has a partially cut shape, and due to the rounded portion and the cut shape, the depth dimension of the main body is not so thin, but the administrator checks the data display 9 for example. The problem that the smoke separator 12 of the present embodiment blocks the field of view during work is avoided to some extent.

  The deodorizing filter 20 according to the present embodiment is replaced because the grill 21 that opens and closes in the front-rear direction is provided on the side surface of the main body case 25 where the suction port 18 of the blower 28 is formed, and the deodorizing filter 20 is detachably provided on the grill 21. Since the rear surface of the grille 21 from which the deodorizing filter 20 is attached and removed with the right hand opened and closed with the right hand can be seen in front, the deodorizing filter 20 can be easily replaced in a short time.

  As shown in FIG. 6, a blowout louver 24 is provided at the blowout port 23, and it is considered that a player does not touch the sirocco fan 16 that is a rotating object by inserting a finger or the like from the blowout port 23. ing. In addition, an operation on / off switch 26 and an output strength switch 27 are provided beside the air outlet 23 so that the player can arbitrarily select operation / stop or switch the size of the air curtain in two stages. can do. With the operation on / off switch 26, for example, when smokers are adjacent to each other and the smoke separation function is not necessary, the operation can be stopped. Further, the output strength switch 27 can be used to perform weak driving for a player who does not like airflow. With these switches, the pachinko store manager who installs the smoke separator 12 does not force the player to use the air curtain function, but can provide a service that can be used by those who need this function as needed. it can.

  As described above, the smoke separation device 12 of the present embodiment can be easily installed between already installed gaming machines. Since installation is easy, for example, a large amount can be installed at night when business hours are over.

  In addition, the player can arbitrarily start / stop or change the size of the air curtain in two stages. With this function, for example, when smokers are next to each other and the smoke separation function is not required, the operation can be stopped, and if the player does not like the air current, it is possible to freely select a weak operation. Thereby, the pachinko shop manager who installs the smoke separator 12 does not force the player to use the function of the air curtain, but provides a service that can be used as needed by those who need this function.

  Regarding the frequency of maintenance and inspection of the game hall manager, the deodorizing filter 20 is replaced about once every three months. Maintenance of the blower 28 is almost unnecessary, and maintenance work can be minimized.

  The smoke distribution device 12 of the present embodiment sucks tobacco smoke from the suction port 18 on the side surface of the main body, but includes a deodorizing filter 20 and further employs a multi-blade fan. Stir efficiently with air and reduce odor. Moreover, it can suppress that the smoke of the tobacco which reached | attained the upper direction of the pachinko machine is re-released from a blower outlet.

  Moreover, since the smoke distribution device 12 of this Embodiment provided the suction inlet 18 of the air blower 28 in the main body side surface, there is no suction inlet in the front and its design property is good. Further, a grille 21 that opens and closes in the front-rear direction is provided on the side of the main body, and the deodorizing filter 20 is detachably provided on the grille 21, so that the rear surface of the grill 21 that attaches and removes the deodorizing filter 20 with the right hand opened and closed can be seen in front. Thus, the deodorizing filter 20 can be easily replaced in a short time.

  Furthermore, since the smoke separator 12 moves the air above the pachinko machine to the lower side of the pachinko machine, the air in the game hall can be efficiently stirred, for example, in winter. In addition, the deodorizing filter 20 can be combined with the function of adsorbing odors in the air to clean the air in the game hall.

  Moreover, in the smoke separator 12 of this Embodiment, as FIG. 3 shows, the left-right corner part of the front surface of the main body case 25 is rounded with a big curvature radius. By doing so, the front-rear width dimension was 125 mm and it seemed to be somewhat thick, but the design was refreshed without obstructing the field of view of the data display device 9. Furthermore, if the main body case 25 is made of a transparent resin or the like, it is possible to further reduce the obstruction of the field of view of the data display device 9.

Next, the capability of the blower 28 will be described. The blower 28 according to the present embodiment has a blade outer diameter Φ85 and a blade width of 45 mm, and is used for, for example, a small duct ventilation fan. The drive motor 13 is a condenser run motor having two poles, and is of a mass production type having a very small size and low power consumption such as used for a pipe fan. The scroll magnification is 0.07, and the scroll width is 64 mm. The blowout port 23 is provided with four blowout louvers 24 having a depth dimension of about 20 mm and a thickness of 2 mm. The left and right width dimensions are 64 mm, which is the same as the scroll width, and the front and rear width dimensions are 55 mm. Excluding 30 cm ² . A deodorizing filter 20 having a size of about 90 mm × 90 mm and a thickness of about 3 mm is provided at the suction port 18 of the blower 28. The pressure loss of the deodorizing filter 20 is about 25 Pa when the air flow rate is 40 m ³ / h and the filter passing air speed is 1.4 m / s.

FIG. 7 is a diagram showing the wind speed measurement position of the air curtain formed by the smoke separator 12. FIG. 8 is an explanatory diagram showing the blown air velocity distribution at a horizontal plane position 80 cm below the blower outlet 23 in the case of normal output of the smoke separator 12. FIG. 9 is an explanatory diagram showing the blown air velocity distribution at a horizontal plane position 50 cm below the blower outlet 23 when the output of the smoke separator 12 is normal. In the above-described state, the capacity of the blower 28 is a frequency of 60 Hz, an air volume of 42.3 m ³ / h, a rotation speed of 1540 / min, an average blown air speed of 3.9 m / s, power consumption of 6.6 W, and noise of 33.0 dB. It was. And the blowing wind which blows off from the blower outlet 23 at this time was biased about 5 degrees to the right side. Therefore, in order to improve the left-right bias of the blown air, the suction port side of the air outlet 23 extending in the left-right direction is blocked by 5 mm. And the left-right width dimension of the blower outlet 23 was 59 mm. The capacity of the blower 28 in this state was as follows: the air volume was 41.7 m ³ / h, the rotational speed was 1550 / min, the average blown air speed was 4.3 m / s, the power consumption was 6.6 W, and the noise was 33.1 dB. This state has the least left-right bias of the blown air from the fan, and the wind speed distribution at the horizontal plane position 80 cm below the outlet 23 is shown in FIG. 8, and the wind speed distribution at the horizontal plane position 50 cm below the outlet 23 is shown in FIG. It became as shown in 9. At this time, the maximum wind speed at a horizontal plane position 160 cm below the outlet 23 was 0.7 m / s, and the front-rear position was about 47 cm. This wind speed distribution is measured at the position shown in FIG. 7, for example, the distance 15 cm in the left-right direction is the blown wind speed at a position 15 cm away from the center of the outlet 23 to the left, and the distance in the left-right direction is -5 cm. Indicates the blowing wind speed at a position 5 cm away from the center of the outlet 23 on the right side.

  Here, the wind speed distribution at the horizontal plane position 50 cm below the blowout port 23 is substantially equal to the blowout wind speed distribution at the height of the position of the player's mouth. The wind speed of 0.3 m / s is the minimum required wind speed for the smoke separation effect in the absence of disturbance, and is a breeze that does not feel airflow. If the wind speed is 0.6 m / s, the smoke separation effect is surely generated. The one shown in FIG. 9 is a case where the output is normal, and the left and right width dimension of the airflow with a wind speed of 0.3 to 0.6 m / s is about 20 cm. Since the player is about 30 cm away, for example, the player does not feel uncomfortable by feeling the air current on the shoulder or the like. Moreover, since the front-rear width dimension of the airflow with a wind speed of 0.3 to 0.6 m / s is about 35 cm, it can be well blocked.

  Further, the wind speed distribution at a horizontal plane position 80 cm below the outlet 23 is the height of the position of the table 11 and is substantially equal to the blown air speed distribution at the position of the ashtray and the position of the electric handle 7. The one shown in FIG. 8 is a case where the output is normal, and the horizontal width dimension of the airflow with a wind speed of 0.3 to 0.6 m / s is about 30 cm. Is about 30 cm away, for example, the left and right width dimensions of airflows with a wind speed of 0.6 m / s or more that the player feels uncomfortable with the hand holding the electric handle 7 are suppressed to about 20 cm. Furthermore, there is no problem because there is a mode function for reducing the output as described later. In this case, smoke from the ashtray can be well blocked and the wind speed is low, so there is no problem with smoking. Further, since the point of the maximum wind speed is about 35 cm in the front-rear direction, even if the depth dimension of the table 11 is 18 cm, an air flow with a high wind speed of the air curtain collides with the table, for example, cigarettes in the ashtray Problems such as ash scattering by the airflow are also eliminated.

Next, in the width direction of the blower outlet 23 of the fan, the suction port side was closed 5 mm, the motor side was closed 5 mm, and the left and right width dimension of the blower outlet 23 was 54 mm. In this state, the capacity of the blower 28 is that the air volume is 40 m ³ / h, the rotation speed is 1560 / min, the average blown air speed is 4.5 m / s, the power consumption is 6.6 W, and the noise is 33.3 dB. At this time, the blown air from the fan was biased to the left by about 4 °. In this way, by closing the left and right width dimensions of the air outlet 23, the right and left bias of the blown air can be improved, and the power consumption and noise due to this are almost unchanged, and the blocking ability is good.

FIG. 10 is an explanatory diagram showing the blown air velocity distribution at a horizontal plane position 80 cm below the outlet 23 of the smoke separator when the output of the smoke separator 12 is reduced by a predetermined amount. FIG. 11 is an explanatory diagram showing the blown air velocity distribution at a horizontal plane position 50 cm below the outlet 23 of the smoke separator when the output of the smoke separator 12 is reduced by a predetermined amount. In the case where the left and right width dimension of the air outlet 23 with improved right and left bias of the blowout air is 59 mm, the output is reduced by a predetermined amount, that is, the rotational speed is reduced to 80%, and the blocking ability is examined. In this state, the capacity of the blower 28 was an air volume of 33.4 m ³ / h, a rotation speed of 1240 / min, an average blown air speed of 3.4 m / s, power consumption of 4.2 W, and noise of 28 dB. In this case, the wind speed distribution at the horizontal plane position 80 cm below the blower outlet 23 is shown in FIG. 10, and the wind speed distribution at the horizontal plane position 50 cm below the blower outlet 23 is as shown in FIG. Further, the maximum wind speed at a horizontal plane position 160 cm below the outlet 23 was 0.6 m / s, and the front-rear position was about 47 cm.

  When the wind speed distribution at a horizontal plane position 50 cm below the air outlet 23 when the output shown in FIG. 11 is reduced by a predetermined amount will be described in detail, the left and right width dimensions of the airflow at a wind speed of 0.3 to 0.6 m / s are output. It was about 20 cm as usual. Moreover, since the front-rear width dimension of the airflow with a wind speed of 0.3 to 0.6 m / s was also about 35 cm, it could be well blocked.

  As shown in FIG. 10, the wind speed distribution at the horizontal plane position 80 cm below the outlet 23 is about 25 cm in the left-right width dimension of the airflow at a wind speed of 0.3 to 0.6 m / s, and the width is larger than the normal output. For example, the right and left width dimension of the airflow of wind speed 0.6 m / s or more which makes the player feel uncomfortable by feeling the airflow at the hand holding the electric handle 7 is suppressed to about 15 cm. In this case, smoke from the ashtray can be well blocked and the wind speed is low, so there is no problem with smoking.

  In general, when the rotational speed of the blower 28 is controlled, the air volume is proportional to the rotational speed, the shaft power is proportional to the third power of the rotational speed, and the noise is proportional to the sixth power of the rotational speed. In the case of a condenser run motor, since the motor efficiency is almost proportional to the rotation speed, the power consumption is reduced by the square of the rotation speed ratio.

  FIG. 14 is an explanatory view showing the blown air velocity distribution at a horizontal plane position 80 cm below the blower outlet 23 of the smoke separator when the output of the smoke separator is minimum. In the above-described state, the output was minimized, that is, the rotation speed was reduced to 70%, and the shutoff capability was examined. FIG. 14 shows the wind speed distribution at a horizontal plane position 80 cm below the outlet 23. The range of the airflow with a wind speed of 0.3 to 0.6 m / s is smaller than that in FIG. 10 when the rotational speed is 80%. Even in this state, there was a smoke separation effect, but because it was easily affected by disturbances, I felt that the output was insufficient.

FIG. 12 is an explanatory diagram showing the blown air velocity distribution at a horizontal plane position 80 cm below the blower outlet 23 of the smoke separator when the output of the smoke separator 12 is reduced by a predetermined amount and the area of the blower outlet 23 is reduced. FIG. 13 is an explanatory diagram showing the blown air velocity distribution at a horizontal plane position 50 cm below the blower outlet 23 of the smoke separator when the output of the smoke separator 12 is reduced by a predetermined amount and the area of the blower outlet 23 is reduced. In the case where the left and right width dimension of the air outlet 23 with improved right and left bias of the blowout air is 59 mm, the left and right ends of the air outlet 23 of the fan are reduced in the state where the output is reduced by a predetermined amount, that is, the rotational speed is reduced to 80%. Both were blocked by 5 mm. That is, the suction port side was 10 mm, the motor side was closed 5 mm, and the left-right width dimension of the air outlet 23 was 49 mm. In this state, the capacity of the blower 28 was an air volume of 33.0 m ³ / h, a rotational speed of 1260 / min, an average blowing wind speed of 3.6 m / s, power consumption of 4.2 W, and noise of 28 dB. In this case, the wind speed distribution at a horizontal plane position 80 cm below the outlet 23 is shown in FIG. 12, and further, the wind speed distribution at a horizontal plane position 50 cm below the outlet 23 is shown in FIG. Further, the maximum wind speed at a point 160 cm below the outlet 23 was 0.5 m / s, and the front-rear position was about 43 cm.

  As shown in FIG. 13, when the output is reduced by a predetermined amount and the width direction of the air outlet 23 is further reduced, the wind speed distribution at the horizontal plane position 50 cm below the air outlet 23 is 0.3 to 0.6 m / s. The horizontal width dimension of the airflow was about 20 cm as in the normal output, and the front-rear width dimension of the airflow with a wind speed of 0.3 to 0.6 m / s was also about 35 cm, so that the airflow could be well blocked.

  As shown in FIG. 12, the wind speed distribution at a horizontal plane position 80 cm below the outlet 23 is about 25 cm in the left-right width dimension of the airflow at a wind speed of 0.3 to 0.6 m / s, and the width is larger than the normal output. small. For example, the right and left width dimension of an airflow with a wind speed of 0.6 m / s or more which makes the player feel uncomfortable by feeling the airflow at the hand portion holding the electric handle 7 is suppressed to about 15 cm. In this case, smoke in the ashtray can be well blocked and the wind speed is low, so there is no problem with smoking. In general, when the air volume is almost the same and the area of the air outlet 23 is reduced, the airflow reaches well halfway, but the attenuation increases as the distance increases. In this case, compared with the case where the size of the air outlet 23 is not reduced, the wind speed distribution at the horizontal plane position 80 cm below the air outlet 23 seems to be slightly improved, but at the time point 160 cm below the air outlet 23. The maximum wind speed was 0.5 m / s, which was slightly lower than 0.6 m / s when the size of the air outlet 23 was not reduced.

  From the above results, the optimum value of the size of the air curtain is, for example, that the player has an air flow on the shoulder or the like in the wind speed distribution at the horizontal plane position 50 cm below the outlet 23 that is approximately equal to the height of the player's mouth. As a wind speed at which the smoke separation effect is surely generated without feeling uncomfortable, the air flow of 0.3 to 0.6 m / s is set to 20 cm to 30 cm in the left-right width dimension, and the front-rear width dimension is set to 35 cm or more so as to be well blocked. I understood that I can do it.

  The wind speed distribution in the horizontal plane position 80 cm below the outlet 23 that is substantially equal to the position of the ashtray or the electric handle 7 is, for example, so that the player does not feel uncomfortable by feeling the air current in the hand part holding the electric handle 7 In order to prevent the ash of cigarettes in the ashtray from scattering, it is necessary to keep the left-right width dimension to 15 to 20 cm with an airflow of 0.6 m / s or more. In addition, as the wind speed at which the smoke separation effect is surely generated, the air flow of 0.3 to 0.6 m / s can be well blocked by setting the left and right width dimension of 20 to 30 cm and the front and rear width dimension of 45 cm or more. I understand.

  In the present embodiment, a pachinko machine at a pachinko store is taken as an example of a large number of gaming machines provided side by side, but the gaming machine is not limited to a pachinko machine and may be, for example, a slot machine. Moreover, although the smoke separation device 12 of this Embodiment is attached to the data display attachment surface 10 between adjacent pachinko machines, it does not necessarily need to be attached to the data display attachment surface 10, and adjacent game machines A predetermined effect can be obtained if it is installed above.

  As described above, the smoke separation device of the present embodiment is installed above adjacent gaming machines such as a pachinko machine or a slot machine, and forms a light air curtain that goes downward from the air outlet 23 provided on the lower surface of the product. The smoke distribution device for blocking the bad smell such as smoke, alcohol, and bad breath of the smoker of the adjacent seat, and the size of the breeze air curtain from the outlet 23 which is almost equal to the height of the player's mouth The horizontal width dimension of the airflow of 0.3 to 0.6 m / s should be about 20 to 30 cm and the front and rear width dimension should be about 35 cm or more at a horizontal plane position below 50 cm. At a horizontal plane position 80 cm below the air outlet 23 substantially equal to the position of the handle 7, the left side of the airflow with a width of about 20 cm, a front-rear direction of about 45 cm or more, and a wind speed of 0.6 m / s or more Width dimension interruption capability and configured to suppress to about 15~20cm is ideal not easily be affected by disturbance.

  With such a configuration, in the smoke separator 12 of the present embodiment, the player is not uncomfortable with the air curtain, and the ash of cigarettes in the ashtray is not blown away. Further, since the maximum wind speed of the floor surface portion is 1.0 m / s or less, dust on the floor surface is not rolled up. Furthermore, even if the air curtain does not function properly to block cigarette smoke due to airflow or movement of people, the smoke can be temporarily prevented from staying in one place, and the odor is also a concern. It can be at a level that can not be. Furthermore, it is possible to suppress the tobacco smoke from staying near the pachinko machine and adhering to, for example, the front glass of the pachinko machine.

  The size of the smoke separation device 12 of this embodiment provided with such an air blower 28 is such that the height dimension is 160 mm, the left and right width dimension is 140 mm, the depth dimension is 125 mm, and the mass is made resin, so that it is about 800 g. I was able to. With regard to product installation work, it is possible to fasten, for example, two drilling screws directly through the back plate of the main body with the main body case 25 removed, and to install a large number of smoke separation devices 12 in a short time. It is possible.

Embodiment 2. FIG.
FIG. 15 is a perspective view of a game arcade where the smoke separation apparatus according to the second embodiment of the present invention is installed. In FIG. 15, the smoke separator 42 of the present embodiment is attached to the maintenance plate 2 further above the data display attachment surface 10. And the distance from the blower outlet (lower surface of the main body) of the smoke distribution device 42 to the player's mouth and the ashtray in this embodiment is about 20 cm larger than that of the first embodiment shown in FIG. The same effect can be obtained by increasing the output.

  In the present embodiment, since the smoke separator 42 is attached to the maintenance plate 2, if the smoke separator 42 is heavy, opening and closing of the maintenance plate 2 is hindered. In recent years, however, condenser run motors have also been developed that are very small and light. By using such a light and small motor, the smoke separator 42 can be reduced to about 500 g. Thereby, attachment to the maintenance plate 2 is also possible. In addition, since the capacitor run motor does not use electronic parts, there is no worry about radio interference to other equipment.

  Also, depending on the location, there is a game arcade where a shelf is provided between the data display mounting surface 10 and the maintenance plate 2, but in such a case, the mounting bracket is used, for example, the mounting bracket is the data It can also be fixed to the display mounting surface 10 and installed so that the smoke separation device 42 comes to the front of the shelf, so that the maintenance plate 2 can be opened and closed.

  Regarding the smoke separators of the first and second embodiments, the power consumption is very low at about 6.6 W per vehicle even during strong operation, and the average number of pachinko machines installed in a pachinko parlor is 1 Even though 300 smoke distribution devices are installed, the total power consumption is very low at 2.0KW, and even if the operation is continued for 14 hours, the electricity bill is about 18 units. About 1,000 yen / month. The noise is about 33 dB in strong driving, but it is about 28 dB in weak driving, and the surroundings are noisy and there is no concern at all.

In addition, the amount of air passing through the deodorizing filter 20 is very small at about 33 m ³ / h per unit in weak operation, but when 300 units of this product are installed, the total air volume becomes 10,000 m ³ / h, and the deodorizing filter 20 Even if a low pressure loss with a thickness of about 3 mm and a deodorizing efficiency as low as 30% are used, the pachinko can be deodorized by operating continuously during business hours, for example. The indoor environment of the entire store can be greatly improved. Furthermore, by operating all hours outside business hours, that is, when operating constantly, there is no stagnation of dirty air, the ventilation efficiency of the exhaust fan is improved, and the indoor environment of the entire pachinko parlor is further improved. Will be.
