Description

TECHNICAL FIELD The present invention relates to a multi-indoor spray system for spraying ozone, ions, mist, etc. indoors with a single device.

Conventionally, large-scale sales facilities such as shopping centers, retail facilities such as convenience stores and household goods stores, meal service facilities such as restaurants, child welfare facilities such as nursery schools, school education facilities, financial institutions, etc., exercise facilities, beauty salons, etc. In order to improve the environment in these facilities, we strive to create comfortable spaces by installing air conditioners, air purifiers, ventilation devices, etc. is coming. In addition, we have installed a sterilization deodorizer, an ozone generator, and a plasma ion generator to create a more comfortable space.

For example, ion generators have effects such as sterilization, deodorization, and antistatic properties, and are widely used in air conditioners and the like.

Ozone generators are used for commercial purposes such as sterilization, deodorization, and freshness maintenance, and are exhibiting excellent effects in sterilization, insecticidal, deodorizing, and the like. On the other hand, it has been pointed out that high concentrations of ozone affect human health. is defined as 0.1 ppm in spatial average. Therefore, there is a restriction that the ozone concentration in human living space cannot be higher than 0.1 ppm.

Ozone water is made by dissolving ozone gas in water by a technique called mixing or bubbling, or by using oxygen contained in water by electrolysis.
Ozone as a gas, as described above, affects the health of the human body in a highly concentrated environment, and requires concentration control. Therefore, examples of its use as "ozonized water" are increasing. Due to the unstable nature of ozone, it returns to oxygen and water in a few tens of minutes, so it can be used as sterilizing water without residue, and is also used when chlorine-based or ethanol-based sterilizers cannot be used. Since it directly destroys and decomposes bacterial cells, it also has the advantage of not producing resistant bacteria.

Hypochlorous acid water is an acidic substance produced by methods such as electrolysis and has an oxidizing effect, so if certain conditions are met, it will exhibit a sterilizing effect against various bacteria and viruses. For this reason, it is used for food disinfection. Hypochlorous acid water is used as a substitute for alcohol disinfectants and sodium hypochlorite.

Recently, however, new infectious diseases have spread worldwide and become a serious problem. As a countermeasure, non-patent document 1 and non-patent document 2 have announced that even low-concentration ozone that does not affect the human body has the effect of reducing the infectivity of new infectious diseases and creating an environment where infection is difficult. ing. For this reason, spraying ozone into the internal space of the above-mentioned facilities is expected to inactivate viruses and the like and have a certain effect in suppressing infectious diseases.

Patent Document 1 discloses an ozone generator using plasma or ultraviolet light, an ozone transport pipe for transporting ozone generated by the ozone generator from the ozone generator to an arbitrary location within a target space, and an ozone transport pipe. An ozone generator is connected to one end of an ozone conveying pipe, and a plurality of ozone discharge ports are provided at the other end to discharge ozone into a target space. An air purification device is disclosed.

It is an air purifier.

In Patent Document 2, an internal ozone sensor for the inside of the ozone generator and an external ozone sensor for the space inside the container or storage are provided in a structure such as a container or storage, and the external ozone concentration becomes a target concentration. As such, an ozone generation system is disclosed that controls power supplied to a fan.

It has a function to control the electric power supplied to the ozone generator so that the concentration reaches the target concentration. The ozone generation system has a function of controlling the power supplied to the fan so that the concentration of ozone is

As a result, the external ozone concentration of the external space containing vegetables, meat, etc., such as the container outside the ozone generator or the inside of the storehouse, can be suitably controlled, so that the sterilization power against fungi and the like can be suitably maintained. It is possible to suitably suppress putrefaction of stored items such as vegetables and meat.

<1. First Embodiment of Multi Indoor Spray System According to Present Disclosure>
[Basic configuration of the first embodiment]
The basic configuration of the first embodiment of the multi indoor spray system 100 according to the present invention will be described below with reference to the drawings.
1, the control panel 101 of the multi indoor spray system 100 according to the present invention is formed in a substantially vertically long rectangular shape, as shown in the plan view of FIG. 1A, the front view of FIG. 1B, and the side view of FIG. 1C. Three spray ports 19, 29 and 39 are arranged side by side at the top. A table 102 protrudes approximately in the middle. In the control panel 101, as shown in FIG. 2, the ozone spraying device 10, the ion spraying device 20, the mist spraying device 30 and the controller 60 are accommodated. In the following description, the "multi indoor spray system 100" may be abbreviated as "this system 100".

The configuration of the multi indoor spray system 100 according to the present invention will be described in more detail. As shown in FIG. 2, the system 100 is roughly composed of an ozone spray device 10, an ion spray device 20, a mist spray device 30, and a controller 60. FIG.

The ozone spray device 10 is a device that generates ozone and sprays the ozone from a spray port 19 .
Ozone is a gas with a unique odor composed of three oxygen atoms. Ozone is generated in an ozone generator 11 . The artificial generation method of ozone includes the plasma discharge method,
There are photochemical action method (UV lamp method), radiation action method, and the like. Plasma discharge methods and photochemical action methods are generally used. Among them, the plasma discharge method is generally widely used because it can produce ozone at low cost.

The plasma discharge method includes a silent discharge method and a creeping discharge method. The silent discharge method is a generation method that utilizes a discharge phenomenon when a high AC voltage is applied between two electrodes via a dielectric such as glass.
The creeping discharge method is a generation method in which ozone is generated by applying a high voltage to a planar electrode covered with an insulator and the insulator to discharge the ozone.

The creeping discharge method is used in small-capacity, small-scale ozone generators because of its simple apparatus. As can be seen from the above generation method, the raw material for generating ozone is air, so ozone can be generated as long as there is a power source necessary for electric discharge.

The ozone generator 11 used in the ozone spray device 10 of the present system 100 is not limited to any of the ozone generation methods described above, and may be any ozone generation method. .

The ozone generated by the ozone generator 11 is, as shown in FIG. Ozone diffused in the space in the facility has a strong oxidizing power, so it oxidizes and destroys the cell membranes of bacteria and viruses in the space and kills them. Also, when it comes into contact with odorous substances, it is oxidatively decomposed and deodorized. Thus, ozone has effects such as disinfection, sterilization, insecticide, and deodorization.

The ion spray device 20 is a device that generates ions and sprays the ions from a spray port 29 .
There are three states of matter: solid, liquid, and gas, and it is known that these phases change when energy such as heat is applied. Among these states, the state with the highest degree of freedom is the gas, and the state of the gas changes to plasma by further applying energy to the gas.

Ions are generated by applying a voltage to the discharge electrode and applying high energy to the gas to cause plasma discharge. The generated ions are hydrogen positive ions (H ⁺ ) generated from water (H ₂ O) in the air and negative oxygen ions (O ₂₋ ) generated from oxygen (O ² ) in the air. is.

Since the generated ions have a positive or negative charge, water molecules (H ₂ O) in the air gather around the sprayed ions. This produces stable, long-lived conjugates of homogeneous molecules called cluster ions.

Plasmacluster ions are formed by water molecules (H ₂ O) gathering around the ions to form a mass, so the ions are stable and do not disappear instantaneously. In other words, it is less affected by the operating environment such as temperature and humidity. Therefore, the ion spray device 20 can spray the generated Plasmacluster ions into the atmosphere and diffuse them into the space of the installation facility.

As a specific configuration, ions generated by the ion generator 21 are sucked by the fan 22 as shown in FIG. sprayed. The sprayed ions are diffused in the installation facility and bring about effects such as sterilization, deodorization, suppression of allergens, and suppression of static electricity.

In addition, as can be seen from the above generation method, since the raw material for generating ions is air as well as ozone, ions can be generated as long as there is a power source necessary for plasma discharge.
Also, the method of generating ions by plasma discharge is common to the plasma discharge method described in the method of generating ozone. Therefore, the ion generator 21 generates a small amount of ozone as a by-product, and this ozone is also sprayed together with the ions. Therefore, in addition to the effect of atomization by ions, the effect of atomization by ozone can also be exhibited.

The mist spraying device 30 transfers the liquid 50a stored in the primary tank 35 to be vaporized and sprayed to the secondary tank 37, and transfers the liquid 50b transferred into the secondary tank 37 into the secondary tank 37. It is a device that vaporizes the substances by an ultrasonic wave generator 40 and sprays them as mist from the spray port 39 . The liquid sprayed as mist includes, for example, ozone water, ionized water, electrolyzed water, hypochlorous acid water, and the like.

Ozonated water is a liquid obtained by dissolving gaseous ozone gas into water. Since ozone as a gas requires concentration control so as not to affect health, management and handling are facilitated by using it as a liquid. Ozone is an unstable substance and returns to oxygen (O ₂ ) and water (H ₂ O) when decomposed, so it is sterilized water without residue.

Electrolyzed water is water to which functions not found in water have been added. For example, there are "alkaline electrolyzed water" and "acidic electrolyzed water" made by electrolyzing water. That is, by electrolyzing water, alkaline electrolyzed water is generated on the negative electrode side and acidic electrolyzed water is generated on the positive electrode side.
Alkaline electrolyzed water mainly has the effect of decomposing proteins and fats and oils, and sterilizing. In addition, acidic electrolyzed water mainly has sterilization and sterilization effects.

Hypochlorous acid water is an acidic solution containing hypochlorous acid, which is an acidic substance produced by a technique such as electrolysis, as a main component. Hypochlorous acid water is said to have a disinfecting effect against staphylococcus aureus, salmonella, norovirus (feline calicivirus), and influenza virus.
In addition, it has been reported that it can be used to disinfect articles against the novel coronavirus (see, for example, Non-Patent Document 3).

Hypochlorous acid water is decomposed when it reacts with organic matter and returns to water, so it is thought to have little effect on the body, but when used in general households, it is recommended only for disinfecting things.
Regarding spatial spraying of hypochlorous acid water in manned spaces, there are no reports of confirmation of the effect so far, but it is thought that knowledge will be accumulated in the future. At present, there is no problem in spraying while paying attention to the space in the installation facility during unmanned hours.

The liquids 50a and 50b used in the mist generator 31 of the mist spraying device 30 of the system 100 are specified as ozone water, ionized water, electrolyzed water, or hypochlorous acid water as described above. Instead, the liquids 50a and 50b other than the above may be, for example, simple water for the purpose of humidification.

The configuration of the mist spraying device 30 will be described below. The primary tank 35 stores a predetermined amount of liquid 50a to be sprayed by the mist generator 31, as shown in FIG. The liquid 50a stored in the primary tank 35 is transferred by the pump 36 to the secondary tank 37 via the water pipe.

That is, the pump 36 is activated when a liquid level sensor (L) 38a arranged below the secondary tank 37 detects that the liquid level in the secondary tank 37 is lowered. The liquid 50 a stored in the primary tank 35 is transferred to the secondary tank 37 by the operation of the pump 36 . As a result, the liquid level of the liquid 50b in the secondary tank 37 rises.

When the liquid level of the liquid 50b in the secondary tank 37 rises and reaches a liquid level sensor (H) 38b disposed above the secondary tank 37, the pump 36 stops operating. As a result, the liquid level falls within the proper range. A flow meter (not shown) may be provided in the water pipe between the primary tank 35 and the secondary tank 37 . This makes it possible to know the operating status and flow rate of the pump 36 .
Further, the primary tank 35 may be provided with a liquid level gauge so that the remaining amount of the liquid 50a can be checked visually. Furthermore, an alarm may be displayed when the remaining amount is low.

An ultrasonic generator 40 is arranged on the bottom surface of the secondary tank 37 as shown in FIG. The ultrasonic generator 40 oscillates at a predetermined frequency to generate ultrasonic waves. Ultrasonic waves generate elastic waves that are inaudible to humans because they vibrate at frequencies outside the range of human hearing. Fine vibrations caused by this elastic wave atomize the liquid 50b in the secondary tank 37 to generate mist. The mist rises upward from the liquid surface of the liquid 50b.

As shown in FIG. 2, the mist generated by the ultrasonic generator 40 in the secondary tank 37 is sucked by the fan 32, passes through the pipes 33 and 34, and flows from the spray port 39 into the space in the installation facility. sprayed. The sprayed mist has a predetermined effect according to the characteristics of each liquid 50a, 50b.

For example, ozonated water mist has an oxidizing power, so it is diffused in the space in the installation facility, and oxidizes and destroys the cell membranes of bacteria and viruses in the space. Also, when it comes into contact with odorous substances, it is oxidatively decomposed and deodorized. In this way, ozonated water provides actions such as disinfection, sterilization, insecticide, and deodorization.

At the same time, the mist spray humidifies the space in the installed facility. It has been reported that increasing humidity results in the inactivation of coronaviruses (see, for example, experimental results in Non-Patent Document 1). Therefore, the mist spraying of the liquids 50a and 50b can exhibit the effect of inactivating the coronavirus by humidification in addition to the effects unique to the liquids 50a and 50b.

Since the first embodiment of the multi-indoor spray system 100 according to the present invention is configured as described above, it can perform ozone spray, ion spray and mist spray, and disinfection, Effects such as sterilization, insecticide, deodorization, suppression of allergens, and suppression of static electricity can be exhibited.

[Spray control of the first embodiment]
Next, the spray control of the first embodiment of the multi indoor spray system 100 according to the present invention will be described based on the drawings. The control unit 60 is a control device that controls operation stoppage of the ozone spray device 10, the ion spray device 20, and the mist spray device 30 that constitute the first embodiment. As shown in FIG. 2, the control unit 60 has a first time switch 61 for switching the ozone spray/ion/mist spray, a second time switch 62 for switching the ion spray/mist spray, and a third time switch for the ozone spray. 63.

The first time switch 61 for switching the ozone spray/ion/mist spray is set in advance to switch on/off times, and when the built-in clock reaches the set time, the set ON/OFF control operation is performed. . The on/off time can be set, for example, at an arbitrary time in a 24-hour cycle in units of minutes.

On/off control is performed by operating the built-in contacts 61a and 61b of the first time switch 61. As shown in FIG. Specifically, for example, when the ON time comes, the connection between the terminal 61c and the contact 61b is switched to the connection between the terminal 61c and the contact 61a. Also, at the off time, the connection between the terminal c and the contact 61a is switched to the connection between the terminal 61c and the contact 61b. As described above, the connection of the terminal 61c is alternately switched between the contact 61a and the contact 61b each time the turn-on time or turn-off time comes, thereby turning the circuit on and off.

The same applies to the second time switch 62 for switching between ion spray/mist spray and the third time switch 63 for ozone spray.

Next, circuit configurations of the first time switch 61, the second time switch 62 and the third time switch 63 will be described. A terminal 61c of the first time switch 61 is connected to the power supply section 41 as shown in FIG.

The power supply unit 41 is, for example, a 24V DC power supply. In this figure, the terminal 61c is connected to the positive terminal of a 24V DC power supply. In addition, when the power supply unit 41 is a DC power supply, the output voltage is not limited to DC24V, and may be DC12V, DC48V or DC100V. In addition, when the equipment constituting each spray device 10, 20 or 30 is an AC specification product, the power supply unit 41 may be a commercial power supply of AC 100V.

A contact 61 a of the first time switch 61 is connected to a terminal 62 c of the second time switch 62 . A contact 61 b of the first time switch 61 is connected to a terminal 63 c of the third time switch 63 .

A contact 63 a of the third time switch 63 is connected to the ozone generator 11 and the fan 12 of the ozone spraying device 10 . A contact 62 b of the second time switch 62 is connected to the ion generator 21 and the fan 22 of the ion spray device 20 . A contact 62 a of the second time switch 62 is connected to the ultrasonic generator 40 and the fan 32 of the mist spraying device 30 .

Since the circuit composed of the first time switch 61, the second time switch 62 and the third time switch 63 is configured as described above, it operates as follows.
When the first time switch 61 is off, the connection between the terminal 61c and the contact 61a is off, and the connection between the terminal 61c and the contact 61b is on. In this state, the terminal 61c of the first time switch 61 and the terminal 63c of the third time switch 63 are connected. Here, when the terminal 63c and the contact 63a of the third time switch 63 are disconnected, the ozone spraying device 10 is stopped because power is not supplied from the power source 41 to the ozone spraying device 10. FIG. At this time, since the terminal 61c and the contact 61a are disconnected, the ion spraying device 20 and the mist spraying device 30 are also stopped.

Next, when the third time switch 63 is turned on, the connection between the terminal 63c and the contact 63a is turned on. Therefore, the power supply unit 41 is connected to the ozone generator 11 and the fan 12 and power is supplied from the power supply unit 41 . As a result, the ozone spraying device 10 is activated, the fan 12 sucks the ozone generated by the ozone generator 11 , and the ozone is sprayed from the spray port 19 .
Since the first time switch 61 is also turned off during this period, the ion spraying device 20 and the mist spraying device 30 are in a stopped state.

Next, when the first time switch 61 is turned on, the connection between the terminal 61c and the contact 61a is turned on. Then, the terminal 61c is connected to the terminal 62c of the second time switch 62 for controlling operation stoppage of the ion spray device 20 or the mist spray device 30 via the contact 61a.

Here, when the second time switch 62 is off, the connection between the terminal 62c and the contact 62b is on. In this state, the power supply unit 41 is connected to the ion spray device 20 via the contact 61 a of the first time switch 61 and the contact 62 b of the second time switch 62 .

Therefore, the power supply unit 41 is connected to the ion generator 21 and the fan 22 and power is supplied from the power supply unit 41 . As a result, the ion spray device 20 is activated, the fan 22 sucks the ions generated by the ion generator 21 , and the ions are sprayed from the spray port 29 .
During this time, the ozone spraying device 10 and the mist spraying device 30 are stopped.

Next, when the second time switch 62 is turned on, the connection between the terminal 62c and the contact 62a is turned on. In this state, the power supply section 41 is connected to the mist spraying device 30 via the contact 61 a of the first time switch 61 and the contact 62 a of the second time switch 62 .

Therefore, the power supply unit 41 is connected to the ultrasonic generator 40 and the fan 32 of the mist spraying device 30 and power is supplied from the power supply unit 41 . As a result, the ultrasonic generator 40 of the mist spraying device 30 is activated to atomize the liquid 50b stored in the secondary tank 37 to generate mist. The fan 32 sucks the mist generated by the mist generator 31 and sprays the mist from the spray port 39 .
On the other hand, since the connection between the terminal 62c and the contact 62b is disconnected, the ion generator 21 and the fan 22 stop, and the ion spray device 20 stops. In other words, both the ozone spraying device 10 and the ion spraying device 20 are stopped during this period.

As described above, according to the multi indoor spraying system 100 according to the present invention, among the ozone spraying device 10, the ion spraying device 20, or the mist spraying device 30, those spraying devices 10, 20, or any one of 30. That is, it is characterized by constituting an exclusive operating circuit so that when any one of the spray devices 10, 20 or 30 is operating, the other spray devices 10, 20 or 30 cannot operate. .

The multi indoor spray system 100 according to the present invention is configured to perform the following intermittent operation in addition to the exclusive operation described above. A specific example of the intermittent operation will be described below. 3A to 3D are time charts for explaining the spray operation of the first embodiment of the multi indoor spray system 100 according to the present invention.

FIG. 3A is a time chart showing the operating state of the first time switch 61. FIG. In this figure, the first time switch 61 is off from 0:00 to 7:00 and from 20:00 to 24:00. Therefore, between 20:00 and 7:00 the next day, the terminal 61c and the contact 61b are on.

FIG. 3B is a time chart showing the operating state of the ozone spraying device 10. As shown in FIG. In the state from 20:00 to 7:00 the next day in FIG. 3A, at 21:00, as shown in FIG. 3B, the third time switch 63 is turned on, and the terminal 63c and the contact 63a are turned on. As a result, the power supply unit 41 is connected to the ozone spraying device 10 and ozone is sprayed from the spray port 19 .

Next, at 22:00, the third time switch 63 is turned off, and the connection between the terminal 63c and the contact 63a is turned off. As a result, the connection between the ozone spraying device 10 and the power supply unit 41 is cut off, and the ozone spraying device 10 stops.

Thereafter, as shown in FIG. 3B, the third time switch 63 is repeatedly turned on and off every hour. That is, it comes on at 21:00 and goes off at 22:00. After that, it turns on at 23:00 and turns off at 24:00. Thereafter, the power is turned on and off every hour, and is turned off at 4:00 the next day. Then, at 21:00 on the same day, the third time switch 63 is turned on to repeat the intermittent operation as described above. That is, between 20:00 and 7:00 the next day, the first time switch 61 is turned off, so that the terminal 61c and the contact 61b are connected. Therefore, in conjunction with the operation of the third time switch 63, the ozone spraying device 10 intermittently operates every hour.

On the other hand, between 7:00 and 20:00, the first time switch 61 is on, so the terminal 61c and the contact 61a are on, and the terminal 61c and the contact 61b are off. Therefore, the ozone spraying device 10 is stopped. Here, even if the third time switch 63 is intermittently turned on and off every hour during this time period, the ozone spraying device 10 cannot be operated. Therefore, the ozone spray device 10 operates as shown in FIG. 3B.

Next, the operation of the ion spray device 20 or the mist spray device 30 during the time period from 7:00 to 20:00 will be described. FIG. 3C is a time chart showing the operating state of the ion spray device 20. FIG. FIG. 3D is a time chart showing the operating state of the mist spraying device 30. As shown in FIG.

During the time period from 7:00 to 20:00, the first time switch 61 is turned on as shown in FIG. 3A. Therefore, the connection between the terminal 61c and the contact 61a is turned on, and the connection between the terminal 61c and the contact 61b is turned off. Therefore, the ozone spraying device 10 is stopped. On the other hand, the operation of the ion spray device 20 or the mist spray device 30 is interlocked with the on/off operation of the second time switch 62 as described below.

Here, the second time switch 62 is turned off between 7:00 and 8:00. Therefore, the connection between the terminal 62c and the contact 62b is turned on. Therefore, as shown in FIG. 3C, the ion spraying device 20 is connected to the power supply unit 41 and power is supplied from the power supply unit 41 . This activates the ion spray device 20 and sprays ions from the spray port 29 . On the other hand, since the connection between the terminal 62c and the contact 62a is disconnected, the mist spraying device 30 is stopped.

Next, the second time switch 62 is turned on between 8:00 and 8:02. Therefore, the connection between the terminal 62c and the contact 62a is ON, and the connection between the terminal 62c and the contact 62b is OFF. Therefore, as shown in FIG. 3C, the connection between the ion spray device 20 and the power supply unit 41 is cut off. This stops the ion spray device 20 . On the other hand, as shown in FIG. 3D , the mist spraying device 30 is connected to the power supply section 41 and power is supplied from the power supply section 41 . As a result, the mist spraying device 30 is activated and mist is sprayed from the spray port 39 .

Next, the second time switch 62 is turned off between 8:02 and 8:20. Therefore, the connection between the terminal 62c and the contact 62b is turned on, and the connection between the terminal 62c and the contact 62a is turned off. Therefore, as shown in FIG. 3C, the ion spraying device 20 is connected to the power supply unit 41 and power is supplied from the power supply unit 41 . This activates the ion spray device 20 and sprays ions from the spray port 29 . On the other hand, as shown in FIG. 3D, the mist spraying device 30 stops.

Thereafter, the ion spraying device 20 and the mist spraying device 30 perform intermittent operation in which the operation and stop are alternately repeated in a cycle of 20 minutes. Specifically, the mist spray device 30 operates for an initial time T1 (eg, 2 minutes), as shown in FIG. 4A, which is an enlarged view of FIG. 3D. The ion spray device 20 operates for the next time T2 (eg, 18 minutes), as shown in FIG. 4B, which is an enlarged view of FIG. 3C. That is, the ion spray device 20 and the mist spray device 30 perform intermittent operation in which the operation and stop are alternately repeated at a period of T1+T2 (that is, 2 minutes+18 minutes=20 minutes).

At 20:00, the intermittent operation by the second time switch 62 is stopped. At the same time, the first time switch 61 is turned off. Therefore, in FIG. 2, the connection between the terminal 61c and the contact 61b is on, and the connection between the terminal 61c and the contact 61a is off. As a result, the ion spray device 20 and the mist spray device 30 are disconnected from the power supply unit 41, and regardless of the intermittent operation of the second time switch 62, the ion spray device 20 and the mist spray device 30 are stopped. . That is, it returns to the state described at the beginning.

Thereafter, the control unit 60 repeats the exclusive operation and intermittent operation of the ozone spray device 10, the ion spray device 20, and the mist spray device 30 in a cycle of 24 hours as described above. The operating time of the first time switch 61, the intermittent operating time of the third time switch 63, or the intermittent operating times T1, T2, or period of the second time switch 62 are merely examples, and the above-mentioned Needless to say, the value is not limited to the time, and may be set to an appropriate value according to the type, scale, internal arrangement, etc. of the facility to be installed.

[Effect of the invention of the first embodiment]
As described above, the multi indoor spray system 100 according to the present invention includes the ozone spray device 10, the ion spray device 20, and the mist spray device 30, and the control unit 60 operates these exclusively and intermittently. (hereinafter referred to as "exclusive intermittent operation" in this specification). In other words, the term "exclusive intermittent operation" as used herein means that, while one spray device is operating, the operation of other spray devices is excluded, two or more spray devices are configured not to operate at the same time, and each spray device each performs intermittent operation in which operation and stop are alternately repeated at predetermined time intervals.

The present invention has the following effects by having such technical features.
(1)
Since the multi indoor spray system 100 according to the present invention can perform ozone spray, ion spray, and mist spray such as ozone water, hypochlorous acid water, and electrolyzed water with one device, each of these spray devices It is possible to exert the effects of sterilization, sterilization, insecticidal, deodorizing, suppressing the action of allergens, and inactivating viruses of infectious diseases by making use of the features of . For example, by spraying ozone during the night hours, mice and cockroaches can be cleared from the kitchen. This creates a clean, safe and comfortable space.
(2)
The mist spraying device 30 of the multi indoor spraying system 100 according to the present invention can use any one of liquid ozone, hypochlorous acid water, ionized water, or electrolyzed water, so it can be used in large-scale sales facilities, retail facilities, restaurants. By using the liquids 50a and 50b corresponding to food facilities such as shops, school education facilities, nursing facilities, hospitals, etc. or various service facilities such as local governments, the risk of outbreaks of infectious disease outbreaks can be reduced.
(3)
The ozone spraying device 10 of the multi indoor spraying system 100 according to the present invention operates the ozone spraying device 10, for example, at night when there are no people in the installation facility, and kills insects such as cockroaches and mites during this time. can be done. Moreover, the ozone is finally decomposed into water and hydrogen, and the operation is stopped at 5:00 the next morning, so that it does not harm the human body thereafter.
Furthermore, the mist spraying device 30 can vaporize and spray ozone water during the daytime when people are in the installation facility, so ozone can be sprayed throughout the day. In addition to the spraying effect of ozone water, it is also possible to humidify the space in the installed facility. As a result, dryness can be prevented, and the effect of inactivating viruses can be brought about by humidification.
(4)
The multi indoor spray system 100 according to the present invention, for example, performs ozone spray during the night time zone from 21:00 to 5:00 the next morning, and performs ion spray or mist spray during the daytime time zone from 7:00 to 20:00. , different types of spray can be applied depending on the time of day.
Moreover, due to the exclusive intermittent operation, two or more of ozone, ions or mist cannot be sprayed at the same time. Therefore, it is possible to exhibit the effect of the unique spraying of the spraying devices 10, 20 and 30 in each spraying time zone.
(5)
Since the multi-indoor spray system 100 according to the present invention operates exclusively intermittently, continuous and overlapping sprays of ozone, ions, mist, or the like do not interfere with each other, and each spray is reliably performed individually. be able to. Moreover, since these sprays are carried out intermittently, the plurality of spray devices 10, 20 and 30 operate simultaneously to spray, which may cause, for example, an abnormal increase in ozone concentration at an unexpected time, resulting in an unexpected health problem. No risk of harm.
(6)
The multi indoor spray system 100 according to the present invention operates exclusively intermittently, so that multiple sprays do not overlap at the same time. For this purpose, the power supply unit 41 of the system 100 should have a capacity corresponding to the maximum power consumption of any one of the spray devices 10, 20 and 30. FIG. Therefore, the power supply unit 41 can be small, and the size and weight of the device can be reduced, the cost can be reduced, and the temperature rise in the control panel 101 can be suppressed. Furthermore, energy saving can be realized.
(7)
The multi indoor spray system 100 according to the present invention can set the time to operate each spray device with a setting device, so the time and time to operate according to the purpose and usage of the facility where it is installed is adjusted. can be centrally managed with a single device. Therefore, each atomizer 10, 20 and 30 can be efficiently operated, and excessive or insufficient atomization of ozone, ions, liquid, etc. can be prevented.
(8)
Since the mist generator 31 includes a primary tank 35 that stores the liquid 50a to be sprayed and a secondary tank 37 that stores the liquid 50b delivered from the primary tank 35, the liquid in the primary tank 35 Even if the residual amount of 50a becomes small, the liquid 50b can be used for spraying for a while. Therefore, it is possible to secure time for replenishing the liquid 50a until the spraying stops due to the liquid running out.
Further, since the ultrasonic generator for vaporizing the liquid 50b by ultrasonic waves is disposed at the bottom of the secondary tank 37, the liquid 51b can be vaporized reliably even if the remaining amount of the liquid 50a is low.
(9)
The multi indoor spray system 100 according to the present invention can set the time and duration for activating each of the spray devices 10, 20 and 30 using general-purpose time switches 61 to 64 and timers 65 and 66, which will be described later. Therefore, even an amateur can easily set the operating time and hours according to the purpose and usage of the facility to be installed, and no specialized knowledge or skills are required to operate the system 100 . Moreover, each of the atomizers 10, 20 and 30 can be efficiently operated, and excessive or insufficient atomization of ozone, ions, liquids, etc. can be prevented.
(10)
The multi indoor spray system 100 according to the present invention has a circuit configuration for exclusive intermittent operation, in which the contact 61a of the first time switch 61 and the terminal 62c of the second time switch 62 are connected, and the contact 61b of the first time switch 61 is connected. is branch-connected to the terminal 63c of the third time switch 63. The contact 63a of the third time switch 63 is connected to the ozone spray device 10, the contact 62b of the second time switch 62 is connected to the ion spray device 20, and the contact 62a is connected to the mist spray device 30.
By constructing such a contact circuit, an exclusive intermittent operation circuit can be formed. That is, in this circuit, only one of the spray devices 10, 20 or 30 is operable, and the operation of the other spray devices 10, 20 or 30 is excluded. Therefore, even if the time switches 61 to 64 malfunction or operate abnormally for some reason, it is theoretically impossible for a plurality of spray devices 10, 20 or 30 to operate at the same time due to the configuration of the contact circuits. Therefore, there is no possibility of over-spraying due to double actuation, and safety is ensured.

[First Modification of First Embodiment]
Next, a first modification of the first embodiment of the multi indoor spray system 100 according to the present invention will be described with reference to the drawings. In the first modification of the first embodiment, the circuit configuration of the control section 60 is composed of one first time switch 61 and two first timers 65 and second timers 66 .

As shown in FIG. 5, the control section 60 of the first modification of the first embodiment includes a first timer 65 in place of the second time switch 62 and a second timer 66 in place of the third time switch 63. It was established. A contact 65 a of the first timer 65 is connected to the mist spray device 30 , and a contact 65 b is connected to the ion spray device 20 . A contact 66 a of the second timer 66 is connected to the ozone spraying device 10 .

In such a configuration, the operation of the control section 60 of the first modified example will be described with reference to the time charts of FIGS. 6A to 6D. Activation of the first time switch 61 is shown in FIG. 6A. Since the operation of the first time switch 61 is the same as the operation of the first time switch 61 shown in FIG. 3A, the explanation is omitted.

The first timer 65 is, for example, turned on between the terminal 65c and the contact 65a for the first two minutes of 20 minutes, and turned off between the terminal 65c and the contact 65a for the remaining 18 minutes. On the other hand, the connection between the terminal 65c and the contact 65b is turned off for the first 2 minutes and turned on for the remaining 18 minutes. Then, the above operation is repeated at intervals of 20 minutes.

Here, in the time zone from 7:00 to 20:00, the contact 61a of the first time switch 61 connected in series with the terminal 65c of the first timer 65 is turned on. Interlocking with the intermittent operation, the ion spray device 20 connected to the contact 65b repeats the intermittent operation as shown in FIG. 6C.
Similarly, mist sprayer 30 connected to contact 65a repeats intermittent operation, as shown in FIG. 6D. Moreover, the ion spraying device 20 and the mist spraying device 30 intermittently repeat operation and stop alternately in conjunction with the alternate switching of the contacts 65a and 65b.

During the time period from 20:00 to 7:00 the next day, the contact 61a of the first time switch 61 connected in series with the terminal 65c of the first timer 65 is off, so as shown in FIG. 6C, The ion spray device 20 connected to the contact 65b is stopped. Similarly, as shown in FIG. 6D, the mist spraying device 30 connected to the contact 65a is also stopped.

As shown in FIG. 6B, for example, the second timer 66 is turned on between the terminal 66c and the contact 66a for the first hour of 24 hours, and turned off between the contacts 65a for the next hour. Then, the above ON and OFF are alternately repeated every hour.

Here, in the time zone from 7:00 to 20:00, the terminal 61c and the contact 61b of the first time switch 61 are disconnected, so the terminal 66c of the second timer 66 connected to the contact 61b Regardless of whether the contact 66a is turned on or off, the ozone spray device 10 connected to the contact 66a will be in a stopped state, as shown in FIG. 6B.

In the time zone from 20:00 to 7:00 the next day, the terminal 61c of the first time switch 61 and the contact 61b are turned on, so the terminal 66c of the second timer 66 connected to the contact 61b is turned on. When the contacts 66a are turned on, the ozone spray device 10 connected to the contacts 66a is activated.

Further, when the terminal 66c and the contact 66a are disconnected, the ozone spraying device 10 connected to the contact 66a stops. Since the second timer 66 intermittently alternately turns on and off at intervals of one hour, the ozone spray device 10 connected to the contact 66a operates and stops every hour as shown in FIG. 6B. Repeat alternately.

The first modification of the first embodiment of the multi indoor spray system 100 according to the present invention is configured as described above, except that it also operates from 5:00 to 8:00. , substantially the same operation as in the case of the basic form of the first embodiment.
Other than the above, it is the same as the basic form of the first embodiment, so the explanation is omitted.

According to the first modification of the first embodiment, the two second time switches 62 and the third time switch 63 can be replaced with the two first timers 65 and the second timers 66. Etc. can be easily handled and the cost can be reduced.

[Second Modification of First Embodiment]
Next, a second modification of the first embodiment of the multi indoor spray system 100 according to the present invention will be described with reference to the drawings. The second modification of the first embodiment is obtained by adding a fourth time switch 64 to the circuit configuration of the controller 60 of the first modification.

Specifically, in the second modification of the first embodiment, as shown in FIG. 7, in the circuit configuration of the control unit 60 of the first modification, the terminal 61c of the first time switch 61 is further connected to the fourth time A terminal 64c is connected to the power supply unit 41 via a contact 64a of the switch 64. As shown in FIG.
Circuit configurations other than the above are the same as those of the second modification of the first embodiment.

In this way, by connecting the contact 64a of the fourth time switch 64 to the terminal 61c of the first time switch 61 in series, when the terminal 64c of the fourth time switch 64 and the contact 64a are turned off, All spray operations of the ozone spray device 10, the ion spray device 20 and the mist spray device 30 can be stopped.

Therefore, in FIG. 7, between 5:00 and 7:00, the connection between terminal 64c and contact 64a of fourth time switch 64 is turned off, and during other time periods it is turned on. During :00, in FIG. 6B, the diffusion time of ozone from the end of ozone spray to the start of ion spray can be ensured.
Other than the above, it is the same as the basic form of the first embodiment, so the explanation is omitted.

According to the second modification of the first embodiment, in addition to the effect of the first modification, for example, during the time period from 5:00 to 7:00, the terminal 64c and the contact 64a of the fourth time switch 64 are By turning it off and turning it on during other time periods, it is possible to adjust the time during which the concentration of ozone is diffused from the end of ozone spray until the start of ion spray, or after the end of ion spray or mist spray. Diffusion time can be secured until spraying is started.

The control unit 60 of the first embodiment of the system 100 has been described as an example configured using the time switches 61 to 64 and the timers 65 and 66, but is not limited to these devices. Alternatively, a microcomputer may be mounted and a control board incorporating the above control functions may be used.

<2. Second embodiment of multi indoor spray system according to the present invention>
[Basic configuration of the second embodiment]
Next, the basic configuration of the second embodiment of the multi indoor spray system 100 according to the present invention will be described with reference to the drawings. The appearance of the control panel 101 of the system 100 is the same as shown in FIGS. 1A, 1B and 1C. In addition, the internal configuration is also common in that the spray devices 10, 20, 30 and the control section 60 are housed in the control panel 101 as shown in FIG.

It is characterized in that it is controlled so that it does not exceed a specified value or stays within a predetermined range.

The control unit 60 of the second embodiment differs from that of the first embodiment in that it is composed of a controller 70 that is an electronic circuit such as a microcomputer. That is, the controller 70 that constitutes the control unit 60 controls the operation and stop of the ozone spray device 10 , the ion spray device 20 and the mist spray device 30 .

A controller 70 that constitutes the control unit 60 is the central part of the control unit 60 . The controller 70 includes an MPU (Micro Processing Unit) 71 that performs arithmetic control, a ROM (Read Only Memory) 72 that stores a control program, and a memory 73 such as a RAM (Random Access Memory) or a flash memory that stores data. , an input/output port 74 for inputting/outputting external signals such as digital signals, contact signals or analog signals to the MPU 71; etc. It also has a clock circuit 76 that counts the time and time that serve as a reference for performing spray control.
Here, the input/output port 74 is an input/output circuit that treats input/output signals as parallel signals. The serial port 75 is an input/output circuit that handles input/output signals as serial signals.

Also, the serial port 75 of the controller 70 is connected to a setting operation display section 77 as shown in FIG. The setting operation display unit 77 performs input of setting values, call-up display of setting contents, operation of the system 100, and display of operation states and alarms.

Further, the setting operation display unit 77 may be configured to be provided with operation switches so that the operation and stop of the ozone spray device 10, the ion spray device 20 and the mist spray device 30 are controlled by manual operation.

The sensor interface 68 is, for example, an interface between various sensors such as the ozone concentration sensor 44 and the controller 70 , and is an interface for converting signals from various sensors into predetermined signals and inputting them into the controller 70 .

As shown in FIG. 8, the sensor interface 68 is connected to an ozone concentration sensor 44, an ion concentration sensor 45, a hypochlorous acid concentration sensor 46, a carbon dioxide concentration sensor 47, a human sensor 48 and/or a humidity sensor 49. be.

The ozone sensor 44 is a sensor that measures the ozone concentration in the facility where the system 100 is installed. The ozone concentration sensor 44 measures not only the ozone concentration sprayed by the ozone spraying device 10 but also the ozone concentration when the mist spraying device 30 sprays mist using ozone water.
The ion concentration sensor 45 is also a sensor that measures the ion concentration within the installation facility. The hypochlorous acid concentration sensor 46 is also a sensor for measuring the hypochlorous acid concentration within the installation facility. The carbon dioxide concentration sensor 47 is also a sensor that measures the carbon dioxide concentration within the installation facility. The human sensor 48 is also a sensor that detects the presence of people in the installation facility. The humidity sensor 49 is also a sensor that measures the humidity in the installation facility.

A controller 70 of the control unit 60 inputs measurement signals or detection signals of various sensors from the ozone sensor 44 to the humidity sensor 49 through the sensor interface 68, and performs control described later.

An input/output port 74 of the controller 70 is connected to the contact control section 67 . The contact control unit 67 turns on and off the contacts 61a, 61b, 62a, 62b, 63a, 64a and the contact 79a. Thereby, the operation and stop of the ozone spray device 10, the ion spray device 20 and the mist spray device 30 are controlled. The circuit configuration of each contact 61a, 61b, 62a, 62b and 63a constitutes a circuit for exclusive intermittent operation of each atomizer 10, 20 and 30 similar to that explained in FIG.

Further, in the contact control section 67, as shown in FIG. 8, a contact 64a is connected in series with the terminal 61c for stopping all the operations of the atomizers 10, 20 and 30. As shown in FIG. The contact point 64a for stopping spraying is a contact point for stopping spraying when the concentration of spraying into the installation facility exceeds a predetermined value or when an abnormality requiring stopping of spraying occurs.
Further, the contact point 64a can also be used to stop all the sprays, similarly to the second modification of the first embodiment, so the description thereof is omitted.

In addition, as shown in FIG. 8, the contact control unit 67 is provided with a ventilation contact 79a for driving or stopping the ventilation fan 43 installed on the wall of the installation facility or the like. The ventilation contact 79a measures the concentration of carbon dioxide in the installation facility with the carbon dioxide concentration sensor 47, and drives or stops the ventilation fan 43 for ventilation when the concentration exceeds a preset value. It is a thing. That is, by turning on the ventilation contact 79a, the ventilation fan 43 is energized with the commercial power supply (AC 100 V), and the ventilation fan 43 is driven to perform ventilation. As a result, the inside of the installation facility is ventilated, and the effect of preventing the spread of infectious diseases and the occurrence of mass infections due to crowded conditions can be exhibited.

The input/output port 74 is also connected to the spray device control section 69 . The spray device control unit 69 is a device in which the controller 70 controls increase/decrease of the spray amount based on measurement signals or detection signals from various sensors 44 , 45 , 46 , 47 , 48 and 49 .

Specifically, the spray device control section 69 outputs a signal for controlling the increase or decrease of the rotation speed of the fan 12, 22 or 32 to the fan rotation speed converter 52, 53 or 54. FIG. As a result, the rotation speed of the fan 12, 22 or 32 increases or decreases, and the amount of spray can be increased or decreased. At the same time, the spray device control unit 69 outputs a signal for increasing or decreasing the output of the ozone generator 11, the ion generator 21, or the ultrasonic generator 40. FIG. As a result, the output of the ozone generator 11, the ion generator 21, or the ultrasonic generator 40 is increased or decreased, and the amount of ozone, ions, mist, or the like generated can be increased or decreased.

The measurement signals or detection signals of the various sensors 44 , 45 , 46 , 47 , 48 and 49 or the setting operation display section 77 may be input/output to/from the controller 70 via the input/output port 74 .

[Control operation of the second embodiment]
Next, based on the flowchart shown in FIG. 9, the control operation of the multi indoor spray system 100 according to the present invention will be described. First, the carbon dioxide concentration in the facility where the system 100 is installed is measured by the carbon dioxide concentration sensor 47, and a measurement signal is input (step S101).

Then, it is determined whether or not the measured carbon dioxide concentration exceeds a preset concentration (step S102).

When the measured concentration of carbon dioxide exceeds a preset concentration, the ventilation contact 79a is turned on to drive the ventilation fan 43 . Thus, the installation facility is ventilated (step S103).

If the measured carbon dioxide concentration does not exceed the preset concentration, the ventilation contact 79a is turned off to stop the ventilation fan 43 (step S104).

Next, the ozone concentration in the installation facility is measured by the ozone concentration sensor 44, and a measurement signal is input (step S105).

Also, it is determined whether or not the current time is within the operating time of the ozone spraying device 10 (step S106).

If the current time is within the operating time of the ozone spraying device 10, it is determined whether or not there is a person in the installation facility based on the detection signal from the human detection sensor 48 (step S107).

When it is determined from the detection signal from the human detection sensor 48 that there is a person in the installation facility, the controller 70 turns off the spray stop contact 64a to stop the ozone spray device 10 (step S108).

When it is determined by the detection signal from the human detection sensor 48 that no one is in the installation facility, the controller 70 keeps the spray stop contact 64a turned on and continues the operation of the ozone spray device 10. (Step S109).

Also, when the current time is not the time period during which the ozone spraying device 10 operates, whether the ozone concentration measured in the installation facility exceeds the preset first control concentration (1st) shown in FIG. It judges (step S110).

If the measured ozone concentration exceeds the preset first control concentration (1st), then it is determined whether or not it exceeds the preset second control concentration (2nd) (step S111). .

When it is determined that the measured ozone concentration exceeds the preset second control concentration (2nd), the controller 70 turns off the spray stop contact 64a to stop the ozone spray device 10. (Step S112).

When it is determined that the measured ozone concentration does not exceed the preset second control concentration (2nd), the controller 70 sends a deceleration signal from the input/output port 74 through the spray device control section 69 to the fan. Output to the rotation speed converter 52 to reduce the rotation speed of the fan 12 . As a result, the amount of ozone sucked by the fan 12 is reduced and the spray amount is suppressed. Also, a decrease signal is output to the ozone generator 11 to suppress the generation of ozone (step S113).

In this case, FIG. 10 shows the relationship between the ozone concentration and the rotation speed of the fan 12 from step S110 to step S113. As shown in the figure, the controller 70 controls the rotation speed of the fan 12 to linearly change in inverse proportion to the ozone concentration within the range between the rated rotation speed (Ra) and the minimum rotation speed (Lr). I do.

Further, in such a configuration, if the fan 12 is driven by an AC power source, the fan rotation speed converter 52 may be composed of an inverter. Further, when the fan 12 is driven by a DC power supply, the fan rotation speed converter 52 may be configured by a variable voltage power supply. The same applies hereinafter.

Also, the first control density (1st) is a set value indicating that the density is a proper value. The second control concentration (2nd) is a set value indicating that the concentration is a defined upper limit or close to the upper limit. The set value of the second control density (2nd) value is larger than the first control density (1st) value. Note that these setting values are set and input on the setting operation display unit 77 for each measurement object. Further, these setting values can be called up and displayed by operating the setting operation display section 77 for display.

Further, the controller 70 may drive the ventilation fan 43 to perform ventilation by turning on the contact 79a for ventilation. As a result, the installation facility is ventilated and the ozone concentration in the installation facility can be kept within the specified value.

Next, the ion concentration is measured by the ion concentration sensor 45 and a measurement signal is input (step S114).

Then, it is determined whether or not the measured ion concentration exceeds the preset value of the second control concentration (2nd) (step S115).

When it is determined that the measured ion concentration exceeds the preset second control concentration (2nd), the controller 70 sends a deceleration signal from the input/output port 74 via the spray device control unit 69 to the fan. It is output to the rotation speed converter 53 to reduce the rotation speed of the fan 22 . As a result, the amount of ions sucked into the fan 22 is reduced, suppressing the spray amount. Also, a signal is output to the ion generator 21 to suppress the generation of ozone (step S116).

Further, it is determined whether or not the measured ion concentration is lower than the preset first control concentration (1st) (step S117).

When it is determined that the measured ion concentration is below the preset first control concentration (1st), the controller 70 outputs a speed-up signal from the input/output port 74 via the spray device control section 69. It is output to the fan rotation speed converter 53 to increase the rotation speed of the fan 22 . As a result, the amount of ions sucked into the fan 22 increases and the spray amount increases. Also, a signal is output to the ion generator 21 to increase the amount of ozone generated (step S118).

Further, when the measured ion concentration does not exceed the preset second control concentration (2nd) and does not fall below the first control concentration (1st), the ion concentration is the predetermined first It is determined that the concentration is within the range between the control concentration (1st) and the second control concentration (2nd), and that the ion spray is performed properly. Then, spraying is continued while controlling the number of revolutions of the fan 22 and the amount of ions generated by the ion generator 21 in the same manner as in the region of step S113 in FIG. 10 (step S119).

Next, the mist concentration control will be described, for example, in the case of mist spraying hypochlorous acid. First, the concentration of hypochlorous acid in the sprayed space is measured by the hypochlorous acid concentration sensor 46, and a measurement signal is input (step S120).

It is determined whether or not the measured concentration of hypochlorous acid exceeds the preset second control concentration (2nd) (step S121).

When it is determined that the measured hypochlorous acid concentration exceeds the preset second control concentration (2nd), the controller 70 controls the input/output port 74 via the spray device control unit 69 A deceleration signal is output to the fan rotation speed converter 54 to reduce the rotation speed of the fan 32 . As a result, the amount of hypochlorous acid mist sucked into the fan 32 is reduced, suppressing the spray amount. Also, a signal is output to the ultrasonic generator 40 to suppress generation of mist (step S122).

Further, it is determined whether or not the measured hypochlorous acid concentration is lower than the preset first control concentration (1st) (step S123).

When it is determined that the measured hypochlorous acid concentration is lower than the preset first control concentration (1st), the controller 70 increases the A speed signal is output to the fan rotation speed converter 54 to increase the rotation speed of the fan 32 . As a result, the amount of hypochlorous acid mist sucked into the fan 32 increases, increasing the spray amount. Also, a signal is output to the ultrasonic generator 40 to increase the amount of hypochlorous acid mist generated (step S124).

When the measured hypochlorous acid concentration does not exceed the preset second control concentration (2nd) and does not fall below the first control concentration (1st), the hypochlorous acid concentration is It is determined that the concentration is within the range between the predetermined first control concentration (1st) and the second control concentration (2nd), and proper ion spraying is being performed. Then, spraying is continued while controlling the rotational speed of the fan 32 and controlling the amount of mist generated by the ultrasonic generator 40 in the same manner as in the region of step S113 in FIG. (Step S125).
In the case of mist spraying, ozone water, ionized water, electrolyzed water, etc., is the same as spraying hypochlorous acid water, so the explanation is omitted.

In addition to measuring the hypochlorous acid concentration, the system 100 measures the humidity in the installation facility with the humidity sensor 49, and when the humidity is below a predetermined value, ozone water, Humidification may be performed by increasing the mist spray amount of the electrolytic solution or the like. As a result, dryness can be prevented, and the effect of inactivating viruses can be achieved by humidification.

<3. Third Embodiment of Multi Indoor Spray System According to the Present Invention>
[Basic configuration of the third embodiment]
Next, the basic configuration of the third embodiment of the multi indoor spray system 100 according to the present invention will be described based on the drawings. The third embodiment of the system 100 is characterized in that the emergency information display device 80 or the water power generator 90 or both of the first or second embodiment is provided.

As shown in FIG. 11, the external shape of the control panel 101 of the third embodiment of the system 100 is substantially the same as the external shape shown in FIG. 1 of the first embodiment. As the emergency information display device 80, for example, a monitor device using a liquid crystal display or the like that is connected to a personal computer or the like and displays an image is used. As shown in the front view of FIG. 11B, the emergency information display device 80 is arranged above the control panel 101 at approximately the height of a person's line of sight. Therefore, the screen of the emergency information display device 80 can be viewed by a person standing in the facility where the system 100 is installed, and the visibility of the displayed image is excellent. Furthermore, the screen size of the emergency information display device 80 may be set to any size by increasing the width dimension of the control panel 101 .

As shown in FIG. 12, the emergency information display device 80 is used by being connected to an image information terminal 81 via, for example, a USB (Universal Serial Bus). Image information terminal 81 is connected to Internet 82 or Wifi network 83 .
From the Internet 82 or the Wifi network 83 (Wi-Fi: "Wi-Fi" is a registered trademark of Wi-Fi Alliance) connected as described above, emergency information such as an earthquake early warning is transmitted. The image information terminal 81 receives the transmitted emergency information and transmits it to the emergency information display device 80 via USB.

The emergency information display device 80 receives emergency information such as an earthquake early warning transmitted from the Internet 82 or the Wifi network 83 and displays it. As a result, people in the installation facility can quickly know the emergency information and can quickly take actions to protect themselves.

As the image information terminal 81, for example, a tablet terminal, a personal computer, or a mobile phone may be used.
Moreover, the emergency information display device 80 may be used as the emergency information display device 80 by attaching a liquid crystal display of a tablet terminal as it is to a predetermined display position of the control panel 101 instead of the monitor device. Also, during normal times, the screen of the emergency information display device 80 may display, for example, news or public relations of local governments. Alternatively, images of advertisements of products, services, etc., of companies, etc., may be broadcast.

3rd Embodiment of this system 100 is provided with the water generator 90 other than the emergency information display apparatus 80. FIG. As shown in FIG. 13, the water power generator 90 has a power generation element that forms a negative electrode 92 inside a substantially rectangular box 91, and a predetermined amount of salt water 96 is injected into the box 91. It is Alternatively, salt water 96 may be generated by injecting water 95 from water inlet 94 by dissolving salt (sodium chloride: NaCl) stored in advance inside box 91 .

A positive electrode 93 is formed on the side surface of the box 91 . The positive electrode 93 is made of, for example, activated carbon, and supplies oxygen (O ₂ ) in the air to the salt water 96 . The power generation element of the negative electrode 92 is made of magnesium (Mg), for example. Also, the salt water 96 is a catalyst that functions as an electrolyte, and does not change itself.

Here, an example of the principle of water power generation will be briefly described. When a load 98 is connected between the positive electrode 93 and the negative electrode 92 via a USB port 97 as shown in FIG. (Mg ²⁺ ) and eluted into the salt water 96, and electrons (e ⁻ ) are generated in magnesium (Mg).
That is, the negative electrode 92 reacts as follows.
Mg → Mg ²⁺ +2e ⁻
The electrons (e ⁻ ) generated on the negative electrode 92 side travel through the load 98 and reach the positive electrode 93 along the route indicated by the dashed-dotted line.

On the positive electrode 93 side, the activated carbon takes in oxygen (O ₂ ) in the air and reacts with electrons (e ⁻ ) transferred from the positive electrode 93 and water (H ₂ O) in the salt water 96 as follows.
1/2(O ₂ )+H ₂ O+2e ⁻ → 2(OH ⁻ )
That is, hydroxyl groups (OH ⁻ ) are generated on the positive electrode 93 side. On the other hand, magnesium ions (Mg ²⁺ ) are produced on the negative electrode 92 side.
Therefore, the following chemical changes occur in the salt water 96 .
Mg ²⁺ +2(OH ⁻ ) → Mg(OH) ₂

As described above, between the positive electrode 93 and the negative electrode 92, as shown in FIG. 13, electrons (e ⁻ ) move to generate a current, and magnesium (Mg) in the negative electrode 92 and oxygen (O ₂ ) reacts with water (H ₂ O) in the salt water 96 to produce magnesium hydroxide (Mg(OH) ₂ ).

The current generated in this way can be used for charging a mobile phone (not shown) connected to a plurality of USB ports 97, for example, as shown in FIG.

Therefore, as shown in FIG. 11B, by arranging a plurality of USB ports 97 in parallel, for example, approximately 100 mm above a table 102 protruding from the front of a control panel 101, a plurality of mobile phone bodies can be connected. They can be placed on the table 102 and each connected to the USB port 97 to be charged simultaneously.

Note that the water power generator 90 loses its function when all of the magnesium (Mg) constituting the negative electrode 92 is changed to magnesium hydroxide (Mg(OH) ₂ ). The power generation element made of magnesium (Mg) may be replaced. Further, when the salt water 96 is reduced due to evaporation or the like over time, water 95 can be added. The water 95 is not limited to tap water, and may be rain water, sea water, muddy water, or the like.

Moreover, since the water generator 90 is constructed as described above and does not have a moving part or a power part, it is silent and does not require maintenance. Although the water generator 90 is a direct current generator, if the output is connected to a DC/AC inverter (not shown) and converted to alternating current, an alternating current power supply such as AC 100V can be obtained.
