Or installed in the control unit 70 from the storage medium.

  Next, the structure of the mist nozzle 50 described above will be described. FIG. 3 is a longitudinal sectional view showing an outline of the configuration of the mist nozzle.

  The mist nozzle 50 has a main body 80. Inside the main body 80, a flow passage 81 through which a liquid sterilizing and deodorizing agent flows is formed. The flow passage 81 is formed such that its inner diameter gradually decreases from the upstream side (secondary branch pipe 21b side) to the downstream side. A filter 82 that removes foreign substances in the sterilizing and deodorizing agent is provided at the proximal end of the flow passage 81. Further, at the other end portion of the flow passage 81, a spout 83 is formed through which a sterilizing deodorant is injected. The inner diameter D of the jet outlet 83 is, for example, 1 mm or less, more preferably 0.1 mm or less. A diffusion means (not shown) for diffusing the mist-like disinfecting deodorant sprayed from the spout 83 is provided near the spout 83.

  When liquid sterilization deodorant is supplied from the secondary branch pipe 21 b to the mist nozzle 50, the sterilization deodorant passes through the filter 82 and flows into the flow passage 81. At this time, the sterilization deodorant passes through the filter 82, so that foreign matters contained in the sterilization deodorant are removed. The sterilizing and deodorizing agent is misted when passing through a fine jet 83 having an inner diameter D. The sterilized sterilizing and deodorizing agent is sprayed from the spout 83 into the indoor space 11. In addition, since the diameter of the sprayed disinfectant and deodorant is very small, people and objects in the indoor space 11 do not get wet. Further, in order to pass through the fine nozzle 83 in this way, the sterilization deodorant needs to be supplied at a high pressure, that is, a pressure higher than the first pressure described above, and is supplied at the second pressure. It is preferable. Therefore, even if water is supplied from the water pipe 30 at the first pressure as described above, this water is hardly ejected from the mist nozzle 50.

  Next, the components of the sterilization deodorant described above will be described. The sterilizing deodorant is an aqueous solution containing about 99.9% pure water and about 0.1% electrolytic hypochlorous acid water. The electrolytic hypochlorous acid water is produced by, for example, mixing ozone, chlorine dioxide and sodium hypochlorite, and electrolyzing the mixed solution. Moreover, the disinfecting and deodorizing agent of the present embodiment has a pH of 8.9, for example. According to the inventors, it has been found that when such a sterilizing and deodorizing agent is sprayed on the indoor space 11, it exhibits an excellent sterilizing effect and an excellent odor eliminating effect. Specifically, for example, Escherichia coli, Staphylococcus aureus, MRSA (methicillin resistant Stahirococcus aureus), Salmonella, Pseudomonas aeruginosa, and spore bacteria can be sterilized. Activation can be suppressed. Moreover, since the electrolytic hypochlorous acid water is harmless to the human body and is a non-polluting substance, it is safe for humans and the environment.

  The sprinkler facility 1 according to the present embodiment is configured as described above. Next, the effect | action performed with the sprinkler installation 1 is demonstrated separately at the time of a normal time and a fire.

During normal times, the controller 70 closes the first on-off valve 22. Then, water does not flow into the secondary side pipe 21 from the water pipe 30. Further, the second opening / closing valve 54 is opened, and the pump 53 is operated based on the operation timing and operation time of the pump 53 input to the control panel of the control unit 70. The pump 53 is operated once every 4 hours and for 5 seconds, for example. Then, a liquid sanitizing deodorant of 50 cm ³ / min is supplied from the tank 52 to the secondary side pipe 21 at a second pressure, and the mist sanitizing deodorant is supplied from the mist nozzle 50 to the indoor space 11. Sprayed. At this time, the sprinkler head 40 is closed, and the sterilization deodorant does not flow out from the sprinkler head 40. The indoor space 11 is sterilized and deodorized by the sprayed mist-like sterilizing and deodorizing agent, and the atmosphere is kept clean. In this embodiment, the operation timing of the pump 53 is set to once every 4 hours based on the knowledge of the inventors that the duration of the sterilization effect by the sterilization deodorant is 4 hours. Is.

On the other hand, in the event of a fire, first, a fire occurrence signal from the sensor 60 or the alarm device 62 is transmitted to the receiver 61 and further transmitted to the control unit 70. At this time, an alarm sound is emitted from the alarm device 62. Then, the control unit 70 closes the second on-off valve 54 and stops the operation of the pump 53. Then, the sterilization deodorant does not flow from the tank 52 into the secondary side pipe 21. Further, the sprinkler head 40 at the fire occurrence location is opened, and the first on-off valve 22 is opened. Then, 50000 cm ³ / min of water is supplied from the water pipe 30 to the secondary side pipe 21 at the first pressure, and water is sprinkled from the sprinkler head 40 into the indoor space 11. At this time, since the pressure of the supplied water is as low as the first pressure, the water is hardly ejected from the mist nozzle 50. The fire is extinguished by the water sprayed in the indoor space 11 in this way.

  According to the above embodiment, the plurality of mist nozzles 50 and the plurality of sprinkler heads 40 are provided in the secondary side pipe 21 respectively, and the controller 70 opens and closes the first on-off valve 22 and the second on-off. By controlling the opening and closing of the valve 54 and the operation of the pump 53, the sterilizing and deodorizing agent can be sprayed from the plurality of mist nozzles 50, and water can be sprayed from the plurality of sprinkler heads 40. Specifically, for example, during normal times, the first on-off valve 22 is closed, the second on-off valve 54 is opened, and the pump 53 is operated every predetermined time to remove the mist nozzle 50 from the tank 52. Supply fungus deodorant. On the other hand, in the event of a fire, for example, the first on-off valve 22 is opened, the second on-off valve 54 is closed, the pump 53 is stopped, and water is supplied from the water pipe 30 to the sprinkler head 40. As described above, according to the sprinkler equipment 1 of the present embodiment, the indoor space 11 can be sterilized and deodorized automatically while maintaining the fire extinguishing function. Therefore, it is not time-consuming as before, and the indoor space 11 can be uniformly sterilized and deodorized. Further, since the plurality of mist nozzles 50 and the like are installed using the fire-extinguishing sprinkler equipment 1, the cost of the apparatus can be reduced. As described above, according to the present embodiment, the atmosphere in the indoor space 11 can be sterilized and deodorized efficiently.

Moreover, when the inventors examined, when the disinfecting deodorant was sprayed on the indoor space 11 under the same conditions as the present embodiment, the inside of the indoor space 11 was compared with the case where the disinfecting deodorant was not sprayed. It was found that there is an effect of lowering the temperature of 2 ° C to 6 ° C. Therefore, for example, in summer, energy consumption required for air conditioning can be suppressed, which can contribute to CO ₂ reduction. Moreover, it turned out that the humidity in the indoor space 11 can be maintained at an appropriate humidity of 50% to 70% by spraying the sterilization deodorant in this way. Therefore, for example, in winter, energy consumption required for humidification can be suppressed, which can contribute to CO ₂ reduction. Furthermore, by keeping the indoor space 11 at an appropriate humidity, virus activation and spread due to drying can be suppressed. As described above, according to this embodiment, it is possible to contribute to environmental conservation.

  Further, the inner diameter D of the ejection port 83 of the mist nozzle 50 is as small as 1 mm or less, and in order to inject the sterilization deodorant from the ejection port 83, the first sterilization deodorant is applied to the mist nozzle 50. It is necessary to supply at a pressure higher than the pressure of. In this regard, during normal times, the sterilization deodorant is supplied from the tank 52 to the mist nozzle 50 at a second pressure higher than the first pressure. Can be injected. On the other hand, in the event of a fire, even if water is supplied from the water pipe 30 at the first pressure, the water is hardly ejected from the mist nozzle 50. Thus, during normal times, a mist-like disinfectant and deodorant is sprayed only from the mist nozzle 50, and water is sprayed only from the sprinkler head 40 during a fire. Therefore, both sterilization and deodorization during normal times and fire extinguishing during fires can be performed appropriately. In the event of a fire, water may flow out of the mist nozzle 50, but the amount is extremely small and does not affect the fire extinguishing in the event of a fire.

  Furthermore, since the inner diameter D of the ejection port 83 of the mist nozzle 50 is as small as 1 mm or less, the diameter of the sterilizing deodorant sprayed from the mist nozzle 50 becomes minute, and people and objects in the indoor space 11 get wet. There is no. Therefore, no unpleasant feeling is given to a person, and an object is not damaged.

  Moreover, since the primary side piping 20 is connected to the water pipe 30, a water supply source can be secured easily. Furthermore, the first on-off valve 22 is closed during normal times, but the water in the water pipe 30 is constantly replaced, so that the water in the primary side pipe 20 and the corrosion and deterioration of the primary side pipe 20 are prevented. Can do.

  Although the above embodiment demonstrated the case where the building 10 had a two-story structure, the structure of a building is not limited to this Embodiment, A various structure can be taken. In the above embodiment, the primary side pipe 20, the secondary side main pipe 21 a and the first on-off valve 22 are provided in the wall body 13, but are installed outside the wall body 13. Also good. Furthermore, in the sprinkler equipment 1 of the above embodiment, the number and arrangement of the sprinkler head 40 and the mist nozzle 50 can be arbitrarily set.

  The preferred embodiments of the present invention have been described above with reference to the accompanying drawings, but the present invention is not limited to such examples. It is obvious for those skilled in the art that various modifications or modifications can be conceived within the scope of the idea described in the claims, and these naturally belong to the technical scope of the present invention. It is understood.

  The present invention is useful when disinfecting and deodorizing indoor spaces using a sprinkler facility for extinguishing fire.
