- water is supplied to the mixing tank 92 and the water stored in the mixing tank 92 is used to perform the humidification operation.
- water flows through the inside of the air purifier 11, so that the hypochlorous acid water adhering to each member is washed away with the water. That is, cleaning processing (removal of hypochlorous acid water) inside the air purifier 11 is performed.
- the air purification control unit 41 After the above procedure, the cleaning process is completed, and the air purification control unit 41 returns to the humidification/purification operation. That is, the air purification control unit 41 causes the hypochlorous acid water generation unit 30 and the space purification device 10 to perform the processing operations again based on the user input information of the operation device 43 .
- the space purification device 10 has an electrolytic bath 31 that stores an aqueous sodium chloride solution, and an electrode 32 that electrolyzes the aqueous sodium chloride solution by energization to generate hypochlorous acid water.

- the air purification control unit 41 controls the hypochlorous acid water generation unit 30, the hypochlorous acid water supply unit 36, the water supply unit 50, and the air purification unit 11.
- the air purification control unit 41 supplies water from the water supply unit 50 to the electrolytic cell 31, and electrolyzes the water stored in the electrolytic cell 31.
- the hypochlorous acid water supply unit 36 is configured to perform a first cleaning operation (a series of operations from step S05 to step S10) in which hypochlorous acid water is supplied to the mixing tank 92.
- the water stored in the electrolytic cell 31 cleans the members including the distribution path from the electrolytic cell 31 to the mixing tank 92, and the components deposited due to the hypochlorous acid water (for example, , sodium chloride, etc.) can be removed. Therefore, in the space purification device 10, clogging in the device can be suppressed even when the device is used continuously for a long period of time.
- hypochlorous acid water for example, , sodium chloride, etc.
- the air purification control unit 41 supplies water from the water supply unit 50 to the mixing tank 92 after the first cleaning operation is completed, and humidifies using the water stored in the mixing tank 92.

- the inside of the air purifier 11 for example, the eliminator 91
- a component for example, chloride sodium, etc.
- each cleaning operation (first cleaning operation, second cleaning operation, operation), but the present invention is not limited to this.
- the humidification/purification operation is continuously performed for a certain period of time (for example, when 24 hours have elapsed)
- the humidification/purification operation by the air purification unit 11 may be stopped and the cleaning operation may be performed.
- the cleaning operation (the first cleaning operation or the second cleaning operation) is periodically performed, so that the occurrence of clogging in the device can be reliably suppressed even when the device is used continuously for a long period of time. be able to.
- the air purification control unit 41 causes the water supply unit 50 to supply
- the first cleaning operation may be controlled such that water is supplied and the water is stored in the electrolytic cell 31 in advance. That is, in such a first cleaning operation, immediately after the hypochlorous acid water supply unit 36 feeds the hypochlorous acid water from the electrolytic cell 31 to the mixing tank 92, the electrolytic cell 31 is filled with water, state, and when the humidification/purification operation is stopped, the subsequent processing is executed. By doing so, the electrolytic bath 31 is in a state in which the electrodes 32 of the electrolytic bath 31 are immersed in water after the supply of the hypochlorous acid water 92 from the electrolytic bath 31 to the mixing bath is finished.
- the inside of the electrolytic cell 31 is left in an empty state, and as the hypochlorous acid water slightly remaining on the surface of the parts including the electrode 32 in the electrolytic cell 31 dries, the hypochlorous acid water The component is concentrated, and the concentrated component can be suppressed from causing local corrosion of the parts including the electrode.
- the first cleaning operation and the second cleaning operation are continuously performed as the cleaning process, but this is not the only option.
- the first cleaning operation and the second cleaning operation may be performed independently, or may be performed at different predetermined timings. Even in this way, the effects described above can be enjoyed.
- the space cleaning device 10 performs the first cleaning operation when the humidification cleaning operation is stopped
- the present invention is not limited to this.
- the first cleaning operation may be performed while the humidification/purification operation is being performed.
- the water generated by the first cleaning operation (the water passed through the electrolytic tank 31 and the like) can be used as water for diluting the hypochlorous acid water in the mixing tank 92 .
- electrolyte components such as sodium chloride in the electrolytic cell 31 are washed away, so that the concentration of hypochlorous acid water generated by electrolysis can be stabilized.
- the space purifying device atomizes hypochlorous acid water and releases it into the air, and is useful as a device for sterilizing or deodorizing the air in a target space.
