There is little influence on. However, since the dust generated from the smoke of cigarettes sucked into the apparatus adheres to the inside of the apparatus, there is a problem that a regular cleaning operation is required, and it takes a lot of trouble for cleaning. In particular, a large number of gaming machines are arranged side by side in the gaming facility, and there is a problem that the man-hours and costs for regularly cleaning the inside of the devices provided in each of these are a major source. is there.

  In addition, when an intake / exhaust port is provided above each gaming machine on the game island, the function may be impaired due to the problem that the aesthetics of the game island are easily lost or the mischief of throwing a game ball into the intake / exhaust port. There is also the problem of being. A large air purifier may be installed at a location away from the gaming machine or amusement island, but even if this can gently purify the air inside the gaming facility, passive smoking for players who play adjacent to each other There is a problem that the effect of preventing this cannot be expected.

  In view of such a problem, the present invention can efficiently discharge dirty air containing tobacco smoke and the like in a gaming facility, air heated by heat generated from a gaming machine, and the like, and An object of the present invention is to provide an exhaust duct device having a structure capable of easily cleaning spears and the like generated and attached due to cigarette smoke, and an amusement facility exhaust system using the exhaust duct device.

  An exhaust duct device according to the present invention has a gaming machine installation island structure (for example, a gaming machine installation island in the embodiment) in which a plurality of gaming machines (for example, pachinko machines PM in the embodiment) are vertically arranged side by side in a row. In the gaming facility having SS1, SS2), it is used for inhaling air that is arranged above each gaming machine and rises along the front side of the gaming machine and exhausts it to the outside. A duct portion that extends left and right at the top of the gaming machine placement portion in the island structure and protrudes forward from the front surface of the gaming machine, and that has a main exhaust space that extends left and right inside, and a lower surface of the duct portion is the front Is formed from a tapered surface (for example, the slope plate portion 21c in the embodiment) that extends obliquely upward toward the front, and is integrally connected to the duct portion at the front portion of the tapered surface and A projecting portion provided with a sub exhaust space communicating with the main exhaust space, and an intake portion having an intake opening provided on the back side of the projecting portion. Configured.

  In this exhaust duct device, a lighting fixture (for example, the fluorescent lamp 27 in the embodiment) is attached to the upper side of the intake portion on the back side of the protrusion, and the tapered surface reflects the illumination light from the lighting fixture. It is preferable that the front surface of the gaming machine be irradiated with indirect illumination light.

  Furthermore, it is preferable that a reflector for reflecting the irradiation light from the illuminating device is provided between the intake portion and the illuminating device on the back surface of the protrusion.

  In the exhaust duct device, it is preferable that a cap that partially closes the intake opening is detachable from the intake portion.

  When the gaming machine is a pachinko machine, it is preferable that a cap opening is formed in the cap, and the cap opening is set to a size that the gaming ball cannot pass through.

  Further, when the gaming machine is a pachinko machine, it is preferable that the intake opening is formed in a slit shape that extends to the left and right, and the opening width of the slit opening is smaller than the diameter of the game ball.

  The gaming facility exhaust system according to the present invention includes a gaming machine installation island structure in which a plurality of gaming machines are erected and held in a row on the left and right sides, and each of the gaming machines that are erected and held in a row. An exhaust duct having the above-described configuration, which is located above and adjacent to and attached to the upper part of the gaming machine installation island structure so as to protrude forward, and is attached by connecting the adjacent main exhaust space and the sub exhaust space. Provided in the left and right ends of the device and the gaming machine installation island structure, and communicated with the main exhaust space and the sub exhaust space of the exhaust duct device located at the left and right ends. A first exhaust passage (for example, the internal space of the first exhaust pipe 11 in the embodiment) and a lower part of the floor or the ceiling of the game facility are provided to extend one end side to the first exhaust passage and the other end. Is provided outside the second exhaust passage (for example, the internal space of the second exhaust pipe 15 in the embodiment) and the second exhaust passage, and the air in the second exhaust passage is transferred to the other end side. And an exhaust fan that exhausts air to the outside.

  In this game facility exhaust system, an ashtray corresponding to each of the game machines installed upright is provided on the gaming machine installation island structure, and the ash and butts in the ashtray are dropped and transported to the left and right ends. It is preferable that a butt collection device for collecting the butt is provided, and a conveyance space of the butt collection device is communicated with the first exhaust passage.

  The exhaust duct device according to the present invention configured as described above is disposed above each gaming machine that is erected and held on the gaming machine installation island structure, and the lower surface of the duct portion that projects forward from the front surface of the gaming machine. Is formed from a tapered surface extending obliquely upward toward the front, and protrudes downward from the front portion of the tapered surface to form a protrusion, forming a bowl-like shape. The smoke generated by smoking by a player who sits in a chair in front of the gaming machine and the air heated by the heat from the gaming machine rises to the front side of the gaming machine. It can be received by the portion that has been formed into a bowl shape by the duct portion and the projection portion, and can be introduced into the intake opening. Therefore, if the air in the main exhaust space and the sub exhaust space is discharged to the outside, the tobacco smoke and the heated air can be efficiently introduced into the main and sub exhaust spaces from the intake opening and exhausted. it can.

  In the exhaust duct device of the present invention, the front surface of the projecting portion is exposed forward in the state of being disposed above each gaming machine in the gaming machine installation island structure, but the back side is visible. Since it is a difficult structure, it is easy to maintain the aesthetics as an appearance in which the exhaust duct device is integrated with the game machine installation island structure by making the front surface of this projection part a shape and color that matches the game island structure. . In addition, since it is configured to introduce cigarette smoke into the main and sub exhaust spaces from the intake opening, the dust contained in the cigarette smoke is most likely to adhere to the intake portion, and it is only necessary to clean the intake opening, Easy to clean.

  In this exhaust duct device, when a lighting fixture is attached to the upper side of the air intake portion on the rear side of the projection, the lighting fixture is shielded from the front side by the projection and is located in a place that cannot be seen by the player. Is reflected by the tapered surface, and the indirect illumination light is irradiated to the front surface of the gaming machine, so that the front surface of the gaming machine can be illuminated with soft illumination light. A gaming machine is often provided with a liquid crystal display device, but because of indirect illumination light, the reflected light of the illumination light applied to the liquid crystal display screen is less likely to enter the player's eyes and make the screen difficult to see, The LCD screen is easier to see. In addition, the smoke of cigarettes rising on the front of the gaming machine can be visually recognized by indirect lighting, and the intake effect can be visually given to the player, thereby giving the smoker a detouring smoking detour effect. it can.

  In addition, the effect of this indirect illumination can be heightened if a reflecting plate is provided between the air intake part and the illuminator on the back surface of the protrusion.

  In the exhaust duct device, by making a cap that partially closes the intake opening detachable from the intake portion, the intake opening area of each exhaust duct device can be adjusted as appropriate. With the gaming machines installed on the island, the exhaust duct devices are connected in a line with the left and right standing in a row, and the air in the main and sub exhaust spaces of the exhaust duct devices located at the left and right ends is sucked When exhausting, the suction force increases as it approaches the end side, but if the suction opening area is adjusted by adjusting the size of the cap and the suction force in all exhaust duct devices is set to be equal, Efficient exhaust can be performed by performing the same suction exhaust for all the gaming machines.

  When the vertical gaming machine is a pachinko machine, if the intake opening is slit-shaped and the opening width (slit width) is smaller than the diameter of the game ball, the game ball is inserted into the interior from the intake opening. It is possible to prevent such mischief.

  On the other hand, in the gaming facility exhaust system according to the present invention having the above-described configuration, the exhaust duct device having the above-described configuration is attached adjacently above each of the gaming machines that are vertically arranged and held in a row in the gaming machine installation island structure. The adjacent main and sub exhaust spaces communicate with each other, the first exhaust passage communicates with the main and sub exhaust spaces, and the first exhaust passage communicates with the second exhaust passage. By exhausting the air in the second exhaust passage to the outside, the air in the main and sub exhaust spaces can be exhausted through the first exhaust passage.

  As a result, when the smoke generated by the player smoking or the air heated by the heat generated from the gaming machine rises up the front side of the gaming machine, the duct portion and the protrusion in the exhaust duct device become trapezoidal. It is received by the portion and efficiently sucked into the intake opening and introduced to the outside through the main and sub exhaust spaces and the first and second exhaust passages. Further, since the intake opening is provided so as to collect the smoke and heat in the middle of the smoke and heat flow in this way, the smoke and heat are effectively transferred to the outside with a small intake amount. It can be discharged, and the decrease in air conditioning efficiency can be suppressed. Thereby, it is not necessary to increase the size of the air conditioning equipment, and the air conditioning cost can be reduced.

  Since the second exhaust passage is provided so as to extend below the floor or the ceiling of the gaming facility, the aesthetics in the gaming facility are not impaired. When the second exhaust passage is provided on the back of the ceiling, it is necessary to form the first exhaust passage from the upper end of the gaming machine installation island to the ceiling, and the first exhaust passage may be exposed in this portion. However, if the second exhaust passage is arranged in the lower part of the floor surface, the first exhaust passage can be directly extended from the gaming machine installation island to the lower part of the floor surface. It can be said that it is preferable to arrange in the above. Furthermore, if the space for arranging the second exhaust passage or the space in the second exhaust passage is used as the electric wiring arrangement space, the electric wiring is not exposed to the game facility, and the space is effectively used. Can be achieved and the aesthetics in the facility are not impaired.

  In this amusement facility exhaust system, when a butt collection device is provided that drops the ash and butts of the ashtray provided in front of each gaming machine of the island structure where the gaming machine is installed and transports them to the end in the left-right direction for recovery processing By connecting the transport space of this butt collection device with the first exhaust passage, not only the smoke and odor in the transport space can be sucked and exhausted, but also the smoke from the cigarette in the ashtray is sucked into the transport space and exhausted. You can also.

There is no risk of damage. In addition, the main and sub exhaust spaces 21d and 23a of each exhaust duct device 20 are connected to each other in a state of being connected to the left and right in this way, and an exhaust space extending as a whole is connected to the left and right.

  In addition, a butt collection device 50 extending left and right is provided on the lower surface of the top plate 4 in the gaming machine installation island structure. As shown in FIG. 5, the cigarette butt collection device 50 is provided with a transport housing 55 that forms a transport space 55 a extending left and right on the lower surface side of the top plate 4, and is hung around the sprocket 53 in the transport housing 55. Further, the conveyor belt conveyor 52 is provided. A plurality of protrusions 52a are formed on the conveyor belt conveyor 52, and the sprocket 53 is rotationally driven to be conveyed in the direction indicated by the arrow. A butt collection box 54 that protrudes downward is formed at the left end of the transport housing 55. The upper surface of the transport housing 55 is formed from the top plate 4, and the lower surface of the ashtray 51 provided on the top plate 4 is exposed to the transport space 55 a in the transport housing 55.

  A hole is made in the lower part of the ashtray 51, and the ash accumulated in the ashtray 51 falls into the conveying space 55a from the hole, is conveyed by the conveying belt conveyor 52, and is stored in the butts collection box 54. ing. Further, the ashtray 51 is rotated so that the butts remaining inside are dropped into the transport space 55a, and transported by the transport belt conveyor 52 to be collected in the butts collection box 54.

  As shown in FIG. 1, an end wall 10 is provided at the end of the gaming machine installation island structure having the above configuration, and the end wall 10 and a pachinko machine PM (most end portion) disposed adjacent thereto are provided. And a pair of front and rear first exhaust pipes 11, 11 extending vertically in the space as shown in FIGS. 6 and 7. It is arranged. The upper ends of the first exhaust pipes 11 and 11 are connected to the exhaust duct devices 20 and 20, and the main and sub exhaust spaces 21 d and 23 a communicate with the internal space of the first exhaust pipe 11. Further, the internal space of the first exhaust pipe 11 communicates with the transfer space 55 of the butt collection device 50 via the connection pipe 12.

  The first exhaust pipe 11 passes through the floor 1 and extends downward, and is connected to a second exhaust pipe 15 disposed in the underfloor space 1 a formed in the lower portion of the floor 1. The second exhaust pipe 15 extends in the underfloor space 1a and extends to the outside of the game facility, and an exhaust fan 16 is provided in the middle of the second exhaust pipe 15 so that the air inside the second exhaust pipe 15 is brought outside by the exhaust fan 16. Discharged. As a result, air in the first exhaust pipe 11 is sucked, and air in the main and sub exhaust spaces 21d and 23a and air in the transfer space 55 are sucked and exhausted. As a result, the air (the air containing the tobacco smoke described above or the air heated by the heat generated from the pachinko machine) flowing to the lower surface side of the exhaust duct device 20 passes through the intake opening 25a and is discharged into the main and sub exhausts. The air is efficiently sucked into the spaces 21d and 23a and exhausted to the outside through the first and second exhaust pipes 11 and 15.

  Thus, when the air is sucked through the intake opening 25a, the suction force in the intake opening 25a of the exhaust duct device 20 disposed closer to the first exhaust pipe 11 is away from the first exhaust pipe 11. The suction force at the intake opening 25a of the exhaust duct device 20 is larger than that, and the exhaust efficiency is unbalanced as it is. For this reason, the above-described cap 29 is attached to appropriately adjust the opening area of the intake opening 25a to balance the exhaust efficiency. Specifically, the cap 29 is attached so as to reduce the opening area of the intake opening 25a on the side close to the first exhaust pipe 11.

  The air in the conveyance space 55 of the butt collection device 50 is also exhausted to the outside through the connection pipe 12 and the first and second exhaust pipes 11 and 15. Thereby, the smoke emitted from the cigarette placed on the ashtray 51 can be sucked into the transport space 55 from the hole formed in the ashtray 51 and the smoke can be prevented from flowing into the game facility. The smell of tobacco can also be removed to prevent this smell from leaking into the game facility.

  In the said embodiment, although the 2nd exhaust pipe 15 is arrange | positioned in the underfloor space 1a, you may arrange | position this in ceiling back space. In this case, the first exhaust pipe 11 extends through the ceiling to the back of the ceiling and is connected to the second exhaust pipe 15.

  The effects of the exhaust duct device according to the present embodiment described above and the gaming facility exhaust equipment using the exhaust duct device are summarized as follows.

  First, the exhaust duct device 20 is disposed above each pachinko machine PM standing and held on the gaming machine installation island structures SS1 and SS2, and the lower surface of the duct part 21 projecting forward from the front surface of the pachinko machine PM (slant). The face plate portion 21c) is formed from a tapered surface that extends obliquely upward toward the front, and protrudes downward from the front portion of the tapered surface to form a protrusion 23 to form a bowl-like shape. Since the air intake portion 24 having the air intake opening 25a is provided, the player who sits in the chair CH in front of the pachinko machine PM and is heated by the smoke generated by smoking and the heat generated from the pachinko machine PM The air rises on the front side of the pachinko machine PM, is received by the hooked portion by the duct portion 21 and the projection portion 23, and can be introduced into the intake opening 25a. Therefore, if the air in the main exhaust space 21d and the sub exhaust space 23a is exhausted to the outside, the tobacco smoke and the heated air are efficiently introduced into the main and sub exhaust spaces 21d and 23a from the intake opening 25a. And can be exhausted.

  In the exhaust duct device 20, the front surface (front plate portion 23 a) of the protrusion 23 is exposed forward in the state where the exhaust duct device 20 is disposed above each pachinko machine PM in the gaming machine installation island structure SS 1, SS 2. Although it is possible to make the rear side of the structure difficult to see, the exhaust duct device 20 is integrated into the gaming machine installation island structure by making the front surface of the projection part a shape and color that matches the gaming island structure. It is easy to maintain the aesthetic appearance. Further, since the smoke of the cigarette is introduced into the main and sub exhaust spaces 21d and 23a from the intake opening 25a, the dust contained in the smoke of the cigarette is most likely to adhere to the intake portion, and the intake opening 25a is cleaned. Cleaning is easy because it is only necessary.

  In this exhaust duct device 20, when a fluorescent lamp 27 is attached above the intake portion 24 on the back side of the projection 23, the fluorescent lamp 27 is shielded from the front side by the projection 23 and cannot be seen by the player. The illumination light is reflected by the tapered surface of the inclined plate portion 21c and the indirect illumination light is irradiated on the front surface of the pachinko machine PM, and the front surface of the pachinko machine PM can be illuminated with the soft illumination light. . The pachinko machine PM is often provided with a liquid crystal display device, but because of the indirect illumination light, the reflected light of the illumination light applied to the liquid crystal display screen hardly enters the player's eyes and makes it difficult to see the screen. The LCD screen is easier to see. In addition, the smoke of cigarettes rising in front of the pachinko machine PM can be visually recognized by indirect lighting, and the intake effect can be visually given to the player, thereby giving the smoker a defensive effect of detouring. Can do.

  In addition, if the reflecting plate 28 is provided between the intake portion 24 and the fluorescent lamp 27 on the back surface of the protrusion 23, the effect of this indirect illumination can be enhanced.
