The total heat exchange unit 92 is a unit that exchanges heat between the air exhausted from the pachinko hall 11 to the outside and the outside air introduced from the outside for air conditioning of the pachinko hall 11.
Specifically, the total heat exchange unit 92 is connected to an outside air introduction port 94 formed in a building wall 93 that separates the machine room 13 from the outside via an outside air introduction pipe 95. Outside air is introduced into the total heat exchange unit 92 through the outside air introduction port 94 and the outside air introduction pipe 95.

It is led out to the dust collection unit 19 via the rear pipe 105.

Here, basic operations during the cooling operation and the heating operation of the air conditioner 10 will be described.
First, the cooling operation will be described.
During the cooling operation, outside air is introduced into the total heat exchange unit 92 through the outside air introduction port 94 and the outside air introduction pipe 95 according to the driving of the pump 96 (see arrow Y1 in FIG. 2). The outside air introduced into the total heat exchange unit 92 is cooled by heat exchange with the air in the pachinko hall 11 introduced through the first indoor air introduction pipe 100 and then passed through the pre-mixing pipe 98. It is led out to the air mixing unit 97 (arrow Y2). During the cooling operation, since the interior of the pachinko hall 11 is cooled, the temperature of the air in the pachinko hall 11 is lower than the temperature of the outside air. Accordingly, in the total heat exchange unit 92, the outside air is cooled by the air in the pachinko hall 11.

In the air mixing unit 97, the outside air introduced through the pre-mixing pipe 98 (arrow Y2) and the air in the pachinko hall 11 introduced through the second indoor air introduction pipe 104 (arrow Y3) are mixed. Then, the mixed air is led out to the dust collection unit 19 through the post-mixing pipe 105 (arrow Y4). Since the air flowing through the pipe 105 after mixing contains the air of the pachinko hall 11, it contains dust such as cigarette smoke.
The air introduced into the dust collection unit 19 via the post-mixing pipe 105 is led out to the use side unit 15 via the duct 20 after the dust is removed by the dust collection unit 19 (arrow Y5).

The air introduced into the usage-side unit 15 through the duct 20 is cooled by the heat exchanger 17 functioning as an evaporator, and then blown upward from the air outlet 23 formed on the top surface 15a by the fan 18. Is done. In addition, the air introduced into the use side unit 15 is air in which the air cooled in the total heat exchange unit 92 and the air of the pachinko hall 11 cooled by the cooling operation are mixed, and is lower in temperature than the outside air. . Therefore, the load on the heat source side unit described above can be reduced, and the operation efficiency in the cooling operation can be improved.
The air blown out from the blow-out port 23 is led to the conditioned air deriving chamber 21 through the duct 22 and then introduced into the air sterilizer main body 120 through the duct 25 (arrow Y6). The conditioned air introduced into the air sterilizer main body 120 is sterilized in the air sterilizer main body 120 and then led out to the supply pipe 29 (arrow Y7). The conditioned air after sterilization introduced into the supply pipe 29 is blown into the pachinko hall 11 through the conditioned air outlet 90 to cool the pachinko hall 11 (arrow Y8).

On the other hand, in the pachinko hall 11, ventilation is performed as needed by exhausting the air in the pachinko hall 11 to the outside. That is, the air conditioner 10 includes ventilation means for guiding the air inside the pachinko hall 11 to the outside of the pachinko hall 11 and introducing the air outside the pachinko hall 11 into the pachinko hall 11.
Specifically, the air in the pachinko hall 11 is led out to the total heat exchange unit 92 via the first indoor air introduction port 99 and the first indoor air introduction pipe 100 (arrow Y9). The air in the pachinko hall 11 introduced into the total heat exchange unit 92 cools the air introduced through the outside air introduction pipe 95 in the total heat exchange unit 92, and then passes through the exhaust pipe 102 and the exhaust port 101. Exhaust to the outside (arrow Y10).

Next, the heating operation will be described.
At the time of heating operation, in the total heat exchange unit 92, the air introduced through the first indoor air introduction pipe 100 is heated by the air in the pachinko hall 11 introduced through the outside air introduction pipe 95. It is different from driving.
Further, the heating operation differs from the cooling operation in that the heat exchanger 17 of the use side unit 15 functions as a condenser and heats the air introduced into the use side unit 15. The air introduced into the use side unit 15 is a mixture of the air heated in the total heat exchange unit 92 and the air of the pachinko hall 11 heated by the heating operation, and is higher in temperature than the outside air. . Therefore, the load of the heat source side unit described above can be reduced, and the operation efficiency in the heating operation can be improved.

Next, each configuration of the air sterilizer 24 will be described.
FIG. 3 is a diagram showing a schematic configuration of the air sterilizer 24.
The air sterilization device 24 includes an air sterilization unit 4 disposed in the air sterilization device main body 120 and an electrolyzed water circulation supply unit 5 disposed adjacent to the air sterilization device main body 120. The electrolyzed water circulation supply unit 5 generates electrolyzed water having sterilizing ability and circulates and supplies it to the air sterilization unit 4. The air sterilization unit 4 supplies electrolyzed water and air supplied from the electrolyzed water circulation supply unit 5. Contact to disinfect air.

  The air sterilization unit 4 includes six element units 40A to 40F. Each of the element units 40A to 40F is configured by combining two gas-liquid contact members. In this embodiment, twelve gas-liquid contact members 41A1 to 41F2 are used. As will be described later, the six element units 40A to 40F are arranged side by side so as to cover almost the entire surface of the air passage 120A formed in the air sterilizer main body 120, and the air passing through the air passage 120A does not leak. It is configured to pass through the gas-liquid contact members 41A1 to 41F2.

The gas-liquid contact members 41A1 to 41F2 are members for bringing the electrolyzed water into contact with the air passing through the air passage 120A, and the air flowing through the air passage 120A in these gas-liquid contact members 41A1 to 41F2 generates a predetermined active oxygen species. By contacting with the electrolyzed water, the virus contained in the air is inactivated and the air is sterilized.
The gas-liquid contact members 41A1 to 41F2 are filter members having a three-dimensional structure similar to a honeycomb structure, and have a structure in which an element portion in contact with a gas is supported by a frame. Although not shown, the element portion is configured by laminating a corrugated plate member and a flat plate member, and a plurality of substantially triangular openings are provided between the corrugated plate member and the flat plate member. Is formed. Therefore, a wide gas contact area is ensured when air is passed through the element portion, electrolysis water can be dripped, and the structure is difficult to clog.

  The element part is made of a material that is hardly deteriorated by electrolyzed water, for example, polyolefin resin (polyethylene resin, polypropylene resin, etc.), PET (polyethylene terephthalate) resin, vinyl chloride resin, fluorine resin (PTFE, PFA, ETFE, etc.) Alternatively, a material such as a ceramic material is used, and in this configuration, a PET resin is used. In addition, the element portion is subjected to a hydrophilic treatment, and the affinity for the electrolyzed water is enhanced, whereby the water retention (wetability) of the electrolyzed water of the gas-liquid contact members 41A1 to 41F2 is maintained, which will be described later. Contact between the active oxygen species (active oxygen substance) and air is sustained for a long time.

  The number of gas-liquid contact members is determined according to the amount of air passing through the air passage 120A of the air sterilizer main body 120, and the amount of air passing through the air passage 120A and the gas-liquid contact members per sheet. A suitable number can be calculated from the sterilization ability (gas contact area), and a number of gas-liquid contact members capable of sufficiently sterilizing the air are arranged in the air sterilization apparatus main body 120. Taking this embodiment as an example, twelve gas-liquid contact members 41A1 to 41F2 are used.

  The electrolyzed water circulation supply unit 5 also includes a water storage tank (water tank) 51, an electrolysis unit 52 that electrolyzes water in the water storage tank 51 to generate electrolyzed water, and the electrolyzed water in the water storage tank 51 to the air. Electrolyzed water supply pipe 56 for supplying the gas-liquid contact members 41A1 to 41F2 of the sterilization unit 4 respectively, an electrolyzed water supply pump 53 provided on the electrolyzed water supply pipe 56, and the electrolyzed water supply pump 53 A branch pipe 54 branched from the electrolyzed water supply pipe 56 on the downstream side and connected to the electrolysis unit 52, a circulating water return pipe 55 for guiding water that has flowed down to a drain pan 44 described later to the water storage tank 51, and the electrolysis unit 52, and a control unit 65 that controls the operation of the electrolyzed water supply pump 53 and the like.

  A water supply pipe 57 for supplying city water (tap water) or the like to the water storage tank 51 and a water supply valve 58 are connected to the water storage tank 51, and the water supply valve 58 is connected to a float switch FS provided in the water storage tank 51. Based on the operation, the controller 65 controls the opening and closing. Here, the water supply source connected to the water supply pipe 57 and supplying water to the water storage tank 51 may be either city water (tap water) or water stored in a water supply tank. The water stored in the water tank or the like may be water that contains ion species such as chloride ions in advance, such as tap water, or a dilute concentration of chloride ions such as well water. When water is used, the water may be adjusted to tap water by adding chloride ions to the water. In the present embodiment, these are collectively referred to as water.

  In this configuration, even when dilute water having a chloride ion concentration such as well water is used for the water storage tank 51, chloride ions are added to this water, and this water is supplied to a predetermined tap water chloride. In order to obtain an ion concentration, a saline tank 59 for storing a salt solution adjusted to a predetermined concentration in advance is provided, and a saline solution supply pipe 61 connected to the saline solution tank 59 is provided with a saline solution supply pump 61. Are connected to the water storage tank 51 via a check valve 62. The saline supply pump 61 is configured to operate under the control of the control unit 65 based on the conductivity detected by the electrolysis unit 52, for example.

  In the present embodiment, the electrolyzed water supply pipe 56 connected to the connection port of the water storage tank 51 is branched into six electrolyzed water supply pipes 56 </ b> A to 56 </ b> F, respectively, and electrolysis sent from the electrolyzed water supply pump 53. Water is divided into the electrolyzed water supply pipes 56A to 56F substantially equally. The electrolyzed water supply pipes 56A to 56F supply electrolyzed water to the element units 40A to 40F, respectively. The electrolyzed water supplied from the electrolyzed water supply pipes 56A to 56F is infiltrated into the gas-liquid contact members 41A1 to 41F2, flows down from these gas-liquid contact members 41A1 to 41F2 through the drain hoses 45A to 45F, and is collected in the drain pan 44. Then, the water returns to the water storage tank 51 through the circulating water return pipe 55.

The electrolysis unit 52 is fixedly disposed on the side surface of the water storage tank 51. Specifically, the electrolysis unit 52 includes a bottomed cylindrical case body 71 and at least a pair of electrodes 72 and 73 housed in the case body 71, and a voltage is applied between the electrodes 72 and 73. By doing so, water is electrolyzed to generate electrolyzed water containing active oxygen species.
Here, the reactive oxygen species are oxygen molecules having an oxidation activity higher than that of normal oxygen and related substances, and so-called narrow definition such as superoxide anion, singlet oxygen, hydroxyl radical, or hydrogen peroxide. These active oxygens include so-called broad active oxygens such as ozone and hypohalous acid.

The electrodes 72 and 73 are, for example, two electrode plates having a base made of titanium (Ti) and a coating layer made of iridium (Ir) and platinum (Pt).
When a voltage is applied between the electrodes 72 and 73, the cathode electrode (cathode) reacts as shown in the following formula (1).
2H ₂ O + 2e ⁻ → H ₂ + 2OH ⁻ (1)
The anode electrode (anode) reacts as shown in the following formula (2).
2H ₂ O → O ₂ + 4H ⁺ + 4e ⁻ (2)
When the reactions at the cathode and anode electrodes are combined, water is electrolyzed as shown in the following formula (3).
2H ₂ O → 2H ₂ + O ₂ (3)
Along with this reaction, in the anode electrode, chlorine ions (chloride ions: Cl ⁻ ) contained in water react as shown in the following formula (4) to generate chlorine (Cl ₂ ).
2Cl ⁻ → Cl ₂ + 2e ⁻ (4)
Further, this chlorine reacts with water as shown in the following formula (5) to generate hypochlorous acid (HClO) and hydrogen chloride (HCl).
Cl ₂ + H ₂ O → HClO + HCl (5)

  Hypochlorous acid (active oxygen species in a broad sense) generated at the anode electrode has a strong oxidizing action and bleaching action. An aqueous solution in which hypochlorous acid is dissolved, that is, electrolyzed water generated by the electrolysis unit 52 exhibits various air cleaning effects such as inactivation of viruses and the like, sterilization, and decomposition of organic compounds. Thus, when the electrolyzed water containing hypochlorous acid flows through the electrolyzed water supply pipes 56A to 56F and is dropped onto the gas-liquid contact members 41A1 to 41F2, the air introduced into the air sterilizer main body 120 is gas-liquid. It contacts with hypochlorous acid in contact member 41A1-41F2. As a result, viruses or the like floating in the air are inactivated, and odorous substances contained in the air react with hypochlorous acid to be decomposed or ionized and dissolved. Accordingly, the air is sterilized and deodorized, and the purified air is discharged from the gas-liquid contact members 41A1 to 41F2.

  An example of influenza virus is given as an action mechanism for inactivating viruses and the like by reactive oxygen species. The above-mentioned reactive oxygen species have the action of destroying and eliminating (removing) the surface proteins (spikes) of viruses that are essential for influenza virus infection. When this surface protein is destroyed, the influenza virus and a receptor (receptor) necessary for the infection of the influenza virus are not bound, and the infection is prevented. For this reason, the influenza virus floating in the air loses infectivity by contacting the electrolyzed water containing active oxygen species in the gas-liquid contact members 41A1 to 41F2, thereby preventing infection.

  Therefore, by arranging the element units 40A to 40F including the gas-liquid contact members 41A1 to 41F2 in the air sterilizer main body 120, the air passing through the air sterilizer main body 120 is removed by the gas-liquid contact members 41A1 to 41F2. The sterilized and sterilized air can be widely distributed in the pachinko hall 11, and air sterilization and deodorization in a large space facility can be performed easily and efficiently.

  Here, switching of the electrodes for applying a positive potential to any side of the electrodes 72 and 73 in the electrolysis unit 52 can be performed by reversing the polarity of the electrodes. In the present embodiment, the control unit This is possible by changing (reversing) the voltage applied to the electrodes 72 and 73 by 65.

Further, the concentration of the active oxygen species in the electrolyzed water is adjusted to a concentration that inactivates viruses to be sterilized under the control of the control unit 65. The concentration of the active oxygen species is adjusted by adjusting a voltage applied between the electrodes 72 and 73 and adjusting a current value flowing between the electrodes 72 and 73.
For example, when a positive potential is applied to the electrode 72 and the current value flowing between the electrodes 72 and 73 is 20 mA (milliampere) / cm ² (square centimeter), the predetermined free residual chlorine concentration (for example, 1 mg (milligram)). ) / L (liter)). Moreover, the concentration of hypochlorous acid in the electrolytic water can be adjusted to a high concentration by changing the voltage applied between the electrodes 72 and 73 and increasing the current value.

  In addition, the water storage tank 51 is provided with a drain pipe 67 that can drain water by a siphon method. The drain pipe 67 includes a first vertical portion 67A that extends upward from the bottom of the water storage tank 51, a horizontal portion 67B that extends to the first vertical portion 67A and extends in a substantially horizontal direction, and a lower portion outside the tank that continues to the horizontal portion 67B. And a second vertical portion 67C extending in the direction. The horizontal portion 67B is provided at a position slightly higher than the control water level in the normal water storage tank 51. By supplying water to this height position, the drain pipe 67 is evacuated. The water in the water storage tank 51 is discharged according to the principle. In this configuration, a drain valve is not required, so that the cost can be reduced and the drainage speed can be improved by the siphon method.

  By the way, in the pachinko hall 11 (FIG. 1), air pollution is relatively severe and the amount of salt water used is large. There is a risk that the saline solution will run short before a predetermined maintenance period (for example, one year). Therefore, the electrolyzed water circulation supply unit 5 of the present embodiment is configured to be connectable to the salt water expansion unit 2 (see FIG. 6) that compensates for the shortage of the salt water in the salt water tank 59.

FIG. 6 is an exploded perspective view showing the electrolyzed water circulation supply unit 5 and the saline solution expansion unit 2.
The saline solution expansion unit 2 is configured by storing a reserve tank (extended salt solution tank) 201 in an expansion case 200. The extension case 200 is formed in a substantially rectangular parallelepiped shape, has a lid 200A that can be attached and detached on the top surface, and has four side surfaces erected on the edge of the bottom plate 200B constituting the bottom surface. These four side surfaces are a rear panel (side surface) 200C formed to have substantially the same size as the rear panel 50F, a front panel 200D facing the back panel 200C, and a pair of side panels facing orthogonally to the panels 200C and 200D. 200E and 200F are provided.

The rear panel 200 </ b> C is attached to the rear surface of the case 50.

FIG. 7 is a plan view showing a state in which the saline solution expansion unit 2 is connected to the electrolytic water circulation supply unit 5. FIG. 8 is a side view showing FIG. 7 from the saline tank side panel 50D side, and illustration of the saline tank side panel 50D and the side panel 200F is omitted. FIG. 9 is a perspective view showing a state in which the brine expansion unit 2 is connected to the electrolytic water circulation supply unit 5.
As shown in FIG. 7, the expansion case 200 is arranged on the back side of the case 50 so as to be aligned with the case 50. The through hole 200 </ b> C <b> 1 is formed so as to be positioned in the gap δ between the water storage tank 51 and the saline tank 59 in a state where the back panel 200 </ b> C is attached to the case 50. The through hole 200D1 is formed so as to face the through hole 200C1 of the back panel 200C attached to the case 50.

The reserve tank 201 is sized to store a sufficient amount of saline solution for a predetermined maintenance period even if salt solution having substantially the same concentration as the saline solution in the saline solution tank 59 is stored. The reserve tank 201 includes a detachable lid member 201A, and the saline solution can be replenished by removing the lid member 201A. The front surface 201B of the reserve tank 201 is formed with a salt water discharge port 201B1 facing the through hole 200D1 at the lower portion. The salt solution discharge port 201B1 is formed using an elastic material such as a fluororesin. The extended pipe 202 is connected.
The reserve tank 201 is disposed close to the back surface (back panel 50F) side of the expansion case 200, and a connection space R is provided between the front surface 201B and the front panel 200D. Thereby, for example, an operator can put a hand from above and can easily connect the saline solution discharge port 201B1 and the extension pipe 202.

  The extension pipe 202 connected to the saline solution discharge port 201B1 extends to the outside of the extension case 200 through the through hole 200D1, and is guided into the case 50 through the through hole 200C1. A portion of the extension pipe 202 exposed to the outside of the extension case 200 is covered with a bellows 203. The extension pipe 202 led into the case 50 through the through hole 200C1 is piped through the gap δ between the adjacent water storage tank 51 and the saline tank 59, and is connected to the end A thereof. It is connected to the connecting portion 205C of the member 205. At this time, the cap (not shown) that has closed the connecting portion 205C is removed.

As shown in FIG. 8, the salt water discharge ports 130 and 201B1 are provided so that their heights H are substantially the same, and the salt water suction pipe 60A and the extension pipe 202 are respectively arranged substantially horizontally. The
After connecting the extension pipe 202 to the saline solution outlet 201B1 and the connecting member 205, as shown in FIG. 9, the lid 50A is attached to the case 50, and the lid 200A is attached to the extension case 200, so that Installation is completed.

Next, the operation of the present embodiment will be described with reference to FIG.
Upstream suction pipe 60A1 is short fry compared to extending extraction pipe 202, the brine feed pump 61 is operated mainly saline is drawn from the brine tank 59 to upstream suction pipe 60A1 is connected, downstream suction The water is supplied into the water storage tank 51 through the pipe 60 </ b> A <b> 2, the saline solution discharge pipe 60 </ b> B, and the salt solution supply unit 85. Since the saline tank 59 and the reserve tank 201 communicate with each other via the extension pipe 202 and the upstream suction pipe 60A1, when the saline supply pump 61 is stopped, the level of the saline water in the saline tank 59 is increased. Then, the saline solution flows from the reserve tank 201 into the saline solution tank 59 until the water level of the saline solution in the reserve tank 201 becomes substantially the same. Thereby, even when the amount of the salt solution used is larger than the amount of the salt solution stored in the salt solution tank 59, the salt solution can be supplied during the predetermined maintenance period.

As described above, the case 50 includes the connecting member 205 that connects the reserve tank 201 in parallel with the saline tank 59, and the extension pipe 202 of the reserve tank 201 is connected to the connecting member 205. The capacity of the saline solution can be increased without changing the size, and thus without changing the case 50. In addition, since the connecting member 205 is formed with a one-touch joint, the extension pipe 202 can be connected to the connecting member 205 with one touch, so that the reserve tank 201 can be easily installed.
Further, since the reserve tank 201 is configured to be able to store a saline solution having the same concentration as the saline solution in the saline tank 59, the saline solution 59 and the reserve tank 201 can be replenished with the same concentration saline solution. It is possible to prevent the work of replenishing water from becoming complicated. Even if the reserve tank 201 is provided, the chloride ion concentration of the saline solution supplied to the water storage tank 51 is constant, so there is no need to change the control of the saline solution supply pump 61.

Further, the rear panel 200C of the expansion case 200 is configured to be replaceable with the rear panel 50F of the case 50, and a through hole 200C1 for guiding the extension pipe 202 into the case 50 is formed in the rear panel 200C. By replacing the 50F and the back panel 200C, for example, there is no need to make a through hole through which the extension pipe 202 passes through the back panel 50F or to prepare a panel having the through hole separately from the extension case 200. Therefore, the reserve tank 201 can be easily connected to the existing case 50 while suppressing an increase in the number of parts.
In the present embodiment, the expansion case 200 is arranged to be aligned with the back side of the case 50. However, since the extension pipe 202 is formed of an elastic member, the expansion case 200 is disposed on the back side of the case 50. Even when a sufficient space cannot be secured, the degree of freedom of the place where the additional case 200 is arranged can be improved by bending the extension pipe 202.

  In addition, since the extension pipe 202 is connected to the saline suction pipe 60A, it is not necessary to provide a separate pump for pumping the saline from the reserve tank 201, and the increase in the number of parts can be suppressed. Further, since the extension pipe 202 is piped through the gap δ between the water storage tank 51 and the saline tank 59 and connected to the connecting member 205 at the end A of the gap δ, the extension pipe 202 is piped. Since it is not necessary to secure a separate space, the piping space S for various pipes such as the pipes 54, 56, 60B, 67, 74, 75, and 78, and control lines and power supply lines is not reduced, and the piping is complicated. There is no need to do. Furthermore, since the through holes 200C1 and 200D1 and the salt solution discharge port 201B1 are formed at positions facing the gap δ, the extension pipe 202 can be piped almost linearly, so that the pipe of the extension pipe 202 can be simplified. .

  As described above, according to the present embodiment, the storage tank 51, the saline tank 59, the electrolysis unit 52, the saline supply pump 61 that supplies the saline from the saline tank 59 to the storage tank 51, and the electrolysis An electrolyzed water supply pump 53 that supplies electrolyzed water from the unit 52 to the gas-liquid contact members 41A1 to 41F2 is housed in a single case 50. In the case 50, the salt water in the saline tank 59 is insufficient. A connecting tank 205 for connecting a reserve tank 201 for storing a saline solution for supplementing in parallel with the saline tank 59 is provided. For this reason, the volume of the saline solution can be increased without changing the saline solution tank 59 and thus the case 50.

Further, according to the present embodiment, since the connecting member 205 is provided in the saline suction pipe 60A that connects the saline tank 59 and the saline supply pump 61, the pump for pumping the saline from the reserve tank 201 is provided. There is no need to provide them separately, and the number of parts can be reduced.
Further, according to the present embodiment, the water storage tank 51 and the salt water tank 59 are disposed adjacent to each other, and the extension pipe 202 is piped through the gap δ between the water storage tank 51 and the salt water tank 59. Since the end portion A of the gap δ is connected to the connection member 205, the provision of the extension pipe 202 can prevent the piping from becoming complicated.

  In addition, according to the present embodiment, the reserve tank 201 is housed in another extension case 200, and the extension case 200 has the rear panel 200C that can be replaced with the rear panel 50F of the case 50. Since the through-hole 200C1 for guiding the extension pipe 202 into the case 50 is formed, a through-hole through which the extension pipe 202 is passed through the rear panel 50F or a panel in which the through-hole is formed is prepared separately from the extension case 200. Therefore, the reserve tank 201 can be easily connected to the existing case 50, and an increase in the number of parts can be suppressed.

In addition, according to the present embodiment, since the connection member 205 is formed with a one-touch joint, the extension pipe 202 can be connected with one touch, so that the reserve tank 201 can be easily installed.
Moreover, according to this Embodiment, since the extension pipe | tube 202 was formed with the elastic member, the freedom degree of the place which arrange | positions the reserve tank 201 can be improved by curving the extension pipe | tube 202. FIG.

However, the above embodiment is an aspect of the present invention, and it is needless to say that the embodiment can be appropriately changed without departing from the gist of the present invention.
For example, in the above-described embodiment, the connection member 205 is provided in the saline suction pipe 60A. However, a separate suction port may be provided in the saline supply pump 61, and this suction port may be used as the connection member.
In the above embodiment, the reserve tank 201 stores substantially the same saline as the saline in the saline tank 59, but stores saline having a concentration different from that of the saline in the saline tank 59. Also good.
In the above embodiment, the pachinko hall 11 is described as an example of a large space facility. However, the present invention is not limited to this as long as it is a large space facility in which the saline tank 59 has a shortage of saline.
