In this way, the air purifying unit 60 is installed so that the lower end portion of the housing 61 is arranged at a position substantially the same height as the ceiling portion 4 (ceiling surface) and is integrated with the ceiling portion 4. As described above, the air purifying unit 60 has a built-in type structure. Further, the air purifying unit 60 is installed at the time of construction of the building 1.

Hereinafter, the flow of sterilizing the indoor air by the sterilization system 20 will be described with reference to FIGS. 1 and 3. The arrows shown by thin lines in FIG. 3 indicate the flow of hypochlorite water. The arrow indicated by the thick line indicates the flow of air.

The sterilization system 20 drives the pump 50 shown in FIG. 1 to supply the hypochlorite water in the reserve tank 30 to the air cleaning unit 60 via the water supply pipe 40. As shown in FIG. 3, the hypochlorite water flows from the connecting pipe 65a of the impregnating portion 65 to the nozzle 65b and is sprayed toward the sterilization filter 64. As a result, the sterilization filter 64 is impregnated (wet) with hypochlorite water.

Further, the air purifying unit 60 introduces the indoor air into the housing 61 through the introduction port 61a by driving the fan 63, and allows the air to pass through the pre-filter 62. At this time, coarse dust contained in the air is collected. After passing through the fan 63, the air passes through the sterilization filter 64 impregnated with hypochlorite water.

At this time, the air comes into contact with the hypochlorous acid water, and pathogens, bacteria and the like contained in the air are removed by the hypochlorous acid. In addition, substances that cause odors (for example, ammonia, etc.) are also removed by hypochlorous acid. In this way, the air from which the pathogens and the like have been removed flows through the downstream side (second space S2 and third space S3) of the sterilization filter 64 and is blown out into the room from the outlet 61b. As a result, the air purifying unit 60 can remove pathogens and the like contained in the indoor air inside the housing 61 and return them to the room (return air).

Further, when air passes through the sterilization filter 64, the hypochlorite water is volatilized. The hypochlorite water (steam) volatilized in this way flows together with air to the downstream side of the sterilization filter 64, and is blown into the room from the outlet 61b. In this way, the air cleaning unit 60 can supply the air containing hypochlorous acid (vapor of hypochlorous acid water) into the room by driving the pump 50 and the fan 63. According to this, the sterilization system 20 can remove pathogens and the like floating in the room with hypochlorous acid and sterilize the air in the room.

Further, by arranging the air cleaning unit 60 (outlet 61b) in the central portion of each room, it is possible to easily supply the air containing hypochlorous acid to the entire room.

As described above, the air purifying unit 60 of the sterilization system 20 is integrated with the ceiling portion 4. That is, the air purifying unit 60 is not mounted on the floor portion 3, but is a structure of the building 1 so as not to reduce the space in which furniture or the like can be installed indoors (for example, it can be mounted on the floor portion 3). It is in a fixed state with respect to the part. In the present specification, the structural portion of the building 1 refers to various members constituting the building 1, specifically, the outer wall portion 2, the floor portion 3, the ceiling portion 4, the partition wall portion 5, and the like. In this way, according to the configuration integrated with the ceiling portion 4 (structural portion), the air purifying unit 60 can be installed in each room of the building 1 without taking up space to sterilize the air in the room. can. In addition, the indoor space required for sterilization can be reduced and the indoor space can be widely used.

Further, the sterilization system 20 stops the supply of hypochlorite water to the air cleaning unit 60 by stopping the driving of the pump 50, and only cleans the air (collects coarse dust). Can be done. Thereby, the air in the room can be sterilized as needed, and the convenience can be improved.

Not limited to. Specifically, for example, by reversing the arrangement of the introduction port 161a and the outlet 161b of the housing, the air introduced into the housing 161 passes through the first space S1, the second space S2, and the third space S3. It may be distributed in order.

Next, the sterilization system 220 according to the third embodiment will be described with reference to FIG.

In the following, the members configured in the same manner as the sterilization system 20 according to the first embodiment are designated by the same reference numerals as those in the first embodiment, and the description thereof will be omitted.

The sterilization system 220 according to the third embodiment is different from the sterilization system 20 according to the first embodiment in that the amount (impregnation amount) of the hypochlorite water impregnated in the sterilization filter 64 is adjusted. .. Hereinafter, a specific description will be given.

The sterilization system 220 includes a reserve tank 30, a water supply pipe 40, a pump 50, an air cleaning unit 60, a valve 270, a motion sensor 280, and a control unit 290.

The valve 270 is for adjusting the amount of hypochlorite water supplied to the air cleaning unit 60. The valve 270 is arranged in the middle of the water supply pipe 40. One valve 270 is provided for each of the plurality of air cleaning units 60. The valve 270 can adjust the amount of hypochlorite water supplied to the air cleaning unit 60 by adjusting the opening degree of the valve body housed in the case.

For example, in the third embodiment, the presence information of a person in the room is detected (acquired) by the motion sensor 280, but the present invention is not limited to this, and other methods may be used to detect it. For example, occupancy information may be detected based on the on / off of the lighting switch. In this case, for example, it is possible to detect that a person is present when the lighting switch is turned on, and it is possible to detect that no person is present when the lighting switch is turned off.

Further, the control unit 290 adjusts the impregnation amount of the hypochlorite water of the sterilization filter 64 according to the signal from the motion sensor 280, but is not limited to this, and for example, the sterilization in the room. May be switched. Specifically, when the control unit 290 receives the signal from the motion sensor 280, the control unit 290 transmits a signal to the valve 270 to close the valve body, and also transmits a signal to the air cleaning unit 60 to operate the fan 63. Stop. As a result, the control unit 290 can stop the sterilization in the room when it is considered that a person is present in the room. Further, the control unit 290 adjusts the opening degree of the valve body to the first opening degree when the signal is not received from the motion sensor 280 for a predetermined time, and drives the fan 63. As a result, the control unit 290 can sterilize the room when it is considered that no person is present in the room.

The control unit 290 may not always sterilize the room when it is considered that the person is not present, but may sterilize the room for a predetermined time after the person leaves the room. For example, the control unit 290 may start sterilization when the time when the signal is not received from the motion sensor 280 exceeds a predetermined threshold value, and may stop sterilization in the room after the lapse of a predetermined time. This makes it possible to prevent excessive supply of hypochlorous acid into the room.

Further, the possibility of sterilization based on the information on the presence of a person is not limited to the above configuration.
