Space purification device

A space purification device comprising:

• a hypochlorous acid water generator including (i) an electrolytic bath that stores a sodium chloride solution, and (ii) an electrode that is energized to electrolyze the sodium chloride solution to generate hypochlorous acid water;
• a mixing bath storing mixture water of the hypochlorous acid water and water;
• a hypochlorous acid water supply unit supplying the hypochlorous acid water from the hypochlorous acid water generator to the mixing bath;
• a water supply unit supplying the water to the electrolytic bath or to the mixing bath;
• a humidifying purification unit that micronizes the mixture water and to release the mixture water micronized into air, by performing a humidifying purification operation using the mixture water stored in the mixing bath;
• and
• a control unit controlling the hypochlorous acid water generator, the hypochlorous acid water supply unit, the water supply unit, and the humidifying purification unit, wherein
• the control unit is configured to, after the humidifying purification operation using the mixture water has finished, perform a first washing operation of causing the water supply unit to supply the water to the electrolytic bath and causing the hypochlorous acid water supply unit to supply the water stored in the electrolytic bath to the mixing bath without performing the electrolyzing,
• wherein the control unit is configured to cause the water supply unit to supply the water to the mixing bath after the first washing operation has finished, and to perform a second washing operation of performing the humidifying purification operation using the water stored in the mixing bath.
