  The present invention will be described below based on the illustrated embodiments.

“Embodiment 1”
“Composition of game hall equipment 1”
1 and 2 are diagrams showing a game hall facility 1 according to Embodiment 1 of the present invention. As shown in FIG. 3, the gaming hall facility 1 is an equipment for exhausting and removing the smoke T1 of the tobacco T in the gaming hall 100 in which a plurality of gaming machines 101 such as pachinko machines and pachislot machines are installed. It mainly includes a blower 2, an intake port (intake means) 3, and a hanging plate (hanging wall) 4.

“Configuration of the blower 2”
The blower device 2 is a device that is disposed on the wall 103 of the game hall 100 and sends air (blast air) A upward along the wall 103. As shown in FIG. (Blower means) 22 and casters (moving means) 23 are provided.

  The main body 21 has a cubic box shape, an air window 211 is provided on a side plate, and an air outlet 212 is provided on an upper surface. The air outlet 212 is composed of a plurality of slits extending horizontally along the wall 103, and is formed so that the air A from the blower 22 flows upward along the wall 103 (so as to crawl the wall 103). . Further, an ashtray 213 is provided on the upper surface of the main body 21 near the air outlet 212, and the smoke T1 of the tobacco T placed in the ashtray 213 is attracted by the air current from the air outlet 212 and flows upward. Yes.

  Here, the smoke T1 of the tobacco T includes the smoke T1 of the tobacco T placed on the ashtray 213, the smoke T1 of the tobacco T held by the smoker M, and the smoke T1 exhaled by the smoker M. Further, if the air A from the blower 22 flows upward along the wall 103, the air outlet 212 may not be configured by a slit.

  The blower 22 is a device that takes in air and sends the air A to the outside with a predetermined pressure and air volume. The blower 22 is housed in the main body 21, takes in air through the air window 211, and moves the air A upward from the blowout port 212. To send. Here, the fan 22 may be of any type such as a fan type or a blower type, and its capacity and air volume are set so that the smoke T1 of the cigarette T can be properly sent to the air inlet 3. . The air window 211 is provided on the side plate of the main body 21, but may be provided on the bottom plate of the main body 21.

  The casters 23 are wheels that move the entire blower 2, can change the traveling direction, and are disposed at the four corners of the bottom surface of the main body 21 via the legs 24. Moreover, the leg body 24 can be expanded-contracted to the up-down direction, and, thereby, the height position of the blower outlet 212 can be changed. Here, for example, as shown in FIG. 1, when the smoker M sits on the sofa (sitting body) 121 and smokes, or as shown in FIG. 2, the smoker M stands up and smokes. The length of expansion and contraction of the leg body 24 is set so that the height of the air outlet 212 can be adjusted near the elbow of the person M. The caster 23 is provided with a stopper for stopping the rotation. As described above, the caster 23 is provided to be movable, but the caster 23 may not be provided.

  Such a blower device 2 is disposed on the wall 103 of the break / passage area 120 of the game hall 100. That is, in the gaming area 110 of the gaming hall 100, as shown in FIG. 3, a plurality of gaming machine islands 102 in which a plurality of gaming machines 101 are linearly arranged are installed in parallel. The rest / passage area 120 is an area that is located outside the game area 110, where people take a break or pass, and is near the wall 103 near the play area 110 of the rest / passage area 120, and The blower 2 is disposed on the wall 103 where the gaming machine 101 can be seen.

  In addition, a plurality of sofas 121 for people to sit on are arranged on a part of the wall 103 of the break / passage area 120, so that not only the smoker M but also a non-smoker can take a break. Note that a large number of the blower devices 2 may be continuously provided or sparsely (dotted) depending on the number of the gaming machines 101 and the like.

“Configuration of air inlet 3”
An air inlet (exhaust port) 3 for sucking air A from the blower 2, smoke T <b> 1 of the cigarette T, and the like is provided in the ceiling 104 of the break / passage area 120. The air intake port 3 is rectangular and extends along the wall 103, and is connected to an exhaust duct and an exhaust fan (not shown) in the ceiling portion 104. Air A and smoke T1 sucked into the air intake port 3 are The air is exhausted to the outside through the exhaust duct.

  The blower 2 is disposed on the wall 103 almost directly below the intake port 3. In other words, the air inlet 3 is disposed almost directly above the blower 2. Moreover, the air blower 2 is arrange | positioned so that the blower outlet 212 may be located in the wall 103 side, and the slit of the blower outlet 212 may extend along the wall 103. FIG.

  In this embodiment, a plurality of blowers 2 are arranged beside the sofa 121 as shown in FIG. 1 or away from the sofa 121 as shown in FIG. Moreover, in the air blower 2 arrange | positioned beside the sofa 121, when the smoker M sits on the sofa 121 and smokes, the height of the air outlet 212 is set as high as possible within the range in which the ashtray 213 can be used. Similarly, in the air blower 2 arranged away from the sofa 121, when the smoker M stands up and smokes, the height of the air outlet 212 is set as high as possible within a range where the ashtray 213 can be used. Thus, although the height of the blower outlet 212 is adjusted using the same air blower 2, you may arrange | position the air blowers 2 from which height differs, respectively.

“Configuration of the hanging plate 4”
The hanging plate 4 is disposed so as to sandwich the air inlet 3 with the wall 103. The drooping plate 4 is flat (planar), the upper end is fixed to the ceiling portion 104 and extends downward, and the wall 103 and the dripping plate 4 sandwich the air intake 3 (the opposite wall of the air intake 3). It is arranged along the wall 103 so as to shield the 103 side. Further, the vertical length of the hanging plate 4 is within a range in which a person or an object can travel to the blower 2 side (the wall 103 side), and the distance L between the air outlet 212 of the blower 2 and the lower end of the drooping wall 4. Is set to be as short as possible. That is, the height from the floor to the lower end of the hanging plate 4 is set to be slightly higher than the height of the person.

  That is, when the distance L is long, the air G from the outside of the hanging plate 4 (on the side opposite to the wall 103), that is, the air G from the outside of the rest / passage area 120 flows into the rest / passage area 120 and The ratio of inhaling the air A from the blower 2 and the smoke T1 of the cigarette T decreases toward the third side. On the other hand, when the distance L is short, the air G from the outside of the rest / passage area 120 is suppressed from flowing into the rest / passage area 120 and to the intake port 3 side. T smoke T1 can be almost attracted. For this reason, the length of the hanging plate 4 is set as long as possible.

  On the other hand, when the distance from the air outlet 212 of the air blower 2 to the air inlet 3 is short, a large amount of air G from outside the break / passage area 120 flows into the break / passage area 120 and the air intake 3 side. Therefore, the drooping plate 4 itself does not have to be provided. That is, by increasing the position of the air outlet 212 to make the distance to the air inlet 3 as short as possible, providing the hanging plate 4 and making the length as long as possible, or both of them, outside the rest and passage area 120 Is suppressed from flowing into the break / passage area 120 and the intake port 3 side. Thereby, there is little fall of the flow velocity of the air A from the air blower 2, and the smoke T1 of the tobacco T, and it is sucked into the inlet 3 quickly and intensively.

  For example, when the position of the air outlet 212 is low as shown in FIG. 1, the wind speed distribution of the air A, the smoke T1, and the like from the blower 2 is a distribution as shown in FIG. That is, in the vicinity of the blower outlet 212 of the blower 2, since only the air A from the blower 2 is almost present, the flow rate is high and the flow rate is almost uniform.

  However, since the gas other than the air A from the blower 2 (smoke T1, air in the break / passage area 120, air G outside the break / passage area 120) is also entrained as it goes upward, the flow velocity is entirely Down and biased. That is, the flow velocity is high in the vicinity of the wall 103, and the flow velocity decreases as the distance from the wall 103 increases (FIG. 5 (b)). Also, the flow velocity is high immediately above the air outlet 212, and the flow velocity is low on both sides of the air outlet 212. (FIG. 5A). Therefore, when the cigarette T is sucked near the air outlet 212 of the blower 2 and near the wall 103, the smoke T1 of the cigarette T is quickly and intensively sucked into the air inlet 3.

"Operation of the game hall facility 1"
Next, the operation of the gaming hall facility 1 having such a configuration will be described.

  First, when a player (smoker M) playing a game in the game area 110 wants to smoke the cigarette T, he can see the gaming machine 101 he / she is using in the break / passage area 120. Go near the blower 2. And when sitting on the sofa 121 and smoking the cigarette T, when the blower 22 of the blower 2 is activated, the air A from the blower 22 flows upward along the wall 103 from the blower outlet 212 as shown in FIG. . When the smoker M smokes the cigarette T in this state, the smoke T1 of the cigarette T flows upward along the wall 103 and is attracted by the airflow of the air A from the blower 2, and together with the air A from the blower 2 It is sucked in by the intake port 3. At this time, the smoker M faces the game area 110 side and can smoke while looking at the gaming machine 101 used by him / her.

  Similarly, also when standing and smoking tobacco T, when the blower 22 of the blower 2 is started, the air A from the blower 22 flows upward along the wall 103 from the blower outlet 212 as shown in FIG. When the smoker M smokes the cigarette T in this state, the smoke T1 of the cigarette T flows upward along the wall 103 and is attracted by the airflow of the air A from the blower 2, and together with the air A from the blower 2 It is sucked in by the intake port 3. Also at this time, the smoker M is facing the game area 110 side and can smoke while looking at the gaming machine 101 used by him / her.

  Here, the blower 22 may always be activated, or may be activated when a person is detected by a human sensor. Moreover, you may adjust the height of the blower outlet 212 of the ventilation apparatus 2 according to the smoker's M height.

  As described above, according to this game hall facility 1, the smoke T1 of the tobacco T is attracted by the airflow from the blower 2 and flows upward along the wall 103, so that the smoke T1 of the tobacco T is more effective. It becomes possible to exhaust the air. Specifically, first, the air A is sent upward along the wall 103 from the blower 2, so that the flow rate of the air A is faster than when there is no wall 103. That is, if air A is sent in the absence of the wall 103, a large amount of air from the surroundings is involved and the flow velocity of the airflow decreases, but sending the air A along the walls 103 reduces the amount of air entrained from the surroundings Little decrease in airflow velocity.

  Furthermore, since the smoke T1 of the tobacco T flows upward along the wall 103, the smoke T1 travels toward the intake port 3 without being disturbed. In this way, the smoke T1 of the tobacco T travels to the intake port 3 at a high flow rate and without being disturbed, so that the smoke T1 of the tobacco T can be sucked in the intake port 3 quickly and intensively. Here, when it is not along the wall 103, the flow rate can be increased by increasing the air volume from the blower 2, but this game hall facility 1 requires a small air volume, while requiring a large amount of power. The flow speed can be increased with electric power, and energy saving can be achieved.

That is,
(1) By flowing the smoke T1 along the wall 103 (jetting on the wall surface), the flow direction of the smoke T1 can be easily fixed, and the smoke T1 is easily sucked by the upper intake port 3.
(2) Since the wall 103 is present, there are few other airflows, and the jet / airflow is not disturbed, so that the air G from outside the rest / passage area 120 does not easily flow.
(3) Since it is attracted only from one side of the wall 103 (rest / passage area 120 side), almost half the air volume is sufficient to obtain the same air velocity. As a result, it can be covered only by replenishing a normal amount of fresh air (only a normal air conditioning load), and energy saving can be achieved.
The effect is obtained.

  In addition, the hanging plate 4 is disposed so as to shield the opposite side wall 103 side of the air inlet 3 and the length of the hanging plate 4 is set as long as possible. Therefore, the air G from outside the rest / passage area 120 However, the flow into the break / passage area 120 and the inlet 3 side is suppressed. Thereby, there is little fall of the flow velocity of the air A from the air blower 2, and the smoke T1 of the tobacco T, and it becomes possible to exhaust the smoke T1 of the tobacco T more effectively. Therefore, even if there is a non-smoker nearby, discomfort to the non-smoker can be suppressed or reduced.

  Further, since the height of the air outlet 212 of the blower 2 is adjustable, the height of the air outlet 212 is adjusted according to the height of the smoker M, the height of the air inlet 3, and the like. It becomes possible to exhaust the smoke T1 of T more effectively. That is, by reducing the distance from the air outlet 212 of the air blower 2 to the air inlet 3 as much as possible, the air G from outside the break / passage area 120 is prevented from flowing between the air blower 2 and the air inlet 3. In addition, the smoke T1 of the tobacco T can be exhausted more effectively.

  On the other hand, since such a blower 2 and further the game hall facility 1 are provided near the wall 103 where the game machine 101 can be seen close to the game area 110, smoke distribution in the game hall 100 is promoted. Is possible. That is, since it is close to the game area 110, the smoker M can easily smoke without going far, and can promote smoking near the wall 103. In addition, since the gaming machine 101 can be seen from the side of the wall 103 of the break / passage area 120, it is necessary to check the gaming machine 101 used by the player and other gaming machines 101 while smoking. And smoking near the wall 103 can be promoted. In this way, it is possible to promote smoke separation such as not smoking (in front of the gaming machine 101) during the game, but going to the break / passage area 120 wall 103 when smoking. , No discomfort to the non-smokers around you during the game.

“Embodiment 2”
7 and 8 are diagrams showing a second embodiment of the present invention. In this embodiment, the air blower 5 is different from that of the first embodiment, and the same components as those of the first embodiment are denoted by the same reference numerals and the description thereof is omitted. The blower 5 includes a blower outlet 51 that blows air A obliquely upward toward the wall 103 from a position separated from the wall 103.

  That is, the air outlet 51 is provided on one side of the upper plate of the main body 21 of the air blower 5, and when the air blower 5 is arranged near the wall 103, the air outlet 51 is separated from the wall 103 by a predetermined distance. It has become. Here, the distance at which the air outlet 51 is separated from the wall 103 is the air A from which the smoke T1 of the cigarette T is blown from the air outlet 51 when the smoker M sucks the cigarette T near the blower 5. It is set to flow upward along the wall 103 by being attracted to (involved by) the air current.

  Moreover, in the blower outlet 51, the 1st guide vane 53 shown in FIG. 7 and the 2nd guide vane 54 shown in FIG. 8 are provided. A plurality of first guide vanes 53 are arranged so as to be obliquely upward from the outlet 51 toward the wall 103. As a result, air A is blown obliquely upward from the outlet 51 at a position away from the wall 103 toward the wall 103. Here, the arrangement angle of the first guide vane 53, that is, the blowing angle of the air A with respect to the wall 103 is set so that the blown air A flows more efficiently along the wall 103. .

  A plurality of second guide vanes 54 are arranged along the wall 103, and the angle can be adjusted in a plane parallel to the wall 103. Thereby, the spread angle of the air A blown out from the blower outlet 51 can be adjusted now.

  And the ashtray 52 is provided so that it may be located between such an outlet 51 and the wall 103, and may be located under the air A which blows off from the outlet 51.

  According to such an embodiment, when the smoker M smokes the cigarette T near the blower 5, the air A is blown obliquely upward toward the wall 103 from the air outlet 51 away from the wall 103. Therefore, the smoke T <b> 1 of the tobacco T flows upward along the wall 103 while being attracted (entrained) by the airflow. And since the blower outlet 51 is separated from the wall 103, the smoke T1 of the tobacco T can be attracted over a wide range. That is, even if the smoker M does not smoke near the wall 103, the smoke T1 of the tobacco T can be effectively exhausted, and the smoking range (degree of smoking freedom) is widened. Further, since the ashtray 52 is provided below the air A blown out from the air outlet 51, the smoke T1 of the cigarette T rising from the ashtray 52 rides on the air flow from the air outlet 51 and more efficiently upwards. Flowing. For this reason, it becomes possible to exhaust the smoke T1 of the tobacco T from the ashtray 52 more effectively.

  Although the embodiment of the present invention has been described above, the specific configuration is not limited to the above embodiment, and even if there is a design change or the like without departing from the gist of the present invention, Included in the invention. For example, in implementation of said invention, although the leg 24 of the air blower 2 expands and contracts, the height of the blower outlet 212 can be changed, but when the main body 21 expands and contracts, the height of the blower outlet 212 is increased. May be changed.

  Moreover, although the drooping wall is constituted by the flat drooping plate 4, it may be constituted by a deformable curtain member. Furthermore, the vertical length of the hanging plate 4 may be adjusted.

  Furthermore, in said embodiment, although the ashtray 213 is provided in the air blower 2, as shown in FIG. 6, it may be made to install an ashtray as a separate body without providing the ashtray 213 in the air blower 2. Good.

  On the other hand, the case where the blower 2 is arranged in the break / passage area 120, that is, the case where the game hall facility 1 is provided in the break / passage area 120 has been described. May be. In the second embodiment of the invention, the arrangement angle of the first guide vane 53 may be adjustable.
