Abstract: An electrolyzed water spraying device of the present disclosure includes: a short-term maintenance water storage portion (30) that stores liquid and requires short-term maintenance; a long-term maintenance water storage portion (31) that stores liquid and requires long-term maintenance; and a notification controller (43) that notifies each of the timing of the next short-term maintenance and the timing of the next long-term maintenance. The notification controller (43) simultaneously performs the notification of the timing of the next short-term maintenance and the notification of the timing of the next long-term maintenance when the timing of the next short-term maintenance and the timing of the next long-term maintenance are close to each other.

Abstract: Space purification device (1000) of the present disclosure includes an electrolytic bath, electrode part (210), a mixing bath, hypochlorous acid water supply part (228), water supply part (138), an air blower, purification part (310), and controller (500). Controller (500) includes count part (550) that counts an elapsed time from timing at which generation of hypochlorous acid water of a first concentration in the electrolytic bath is completed, and calculation part (560) that calculates, based on a count time counted by count part (550), a concentration decrease value indicating how much the first concentration of the hypochlorous acid water in the electrolytic bath is decreased. Controller (500) is configured to adjust a supply amount of hypochlorous acid water to be supplied from hypochlorous acid water supply part (228) based on the concentration decrease value.

Abstract: A space purification device according to the present disclosure includes: electrolysis bath; water supply unit; electrode unit (140); first calculator (510) that calculates an increased concentration of hypochlorous acid water per unit time based on (i) a first sodium chloride concentration that is a sodium chloride concentration in the electrolysis bath after the sodium chloride concentration has changed due to an input of the electrolysis accelerator into the electrolysis bath and (ii) hypochlorous acid generation efficiency per unit time set in advance; second calculator (512) that calculates, based on a target hypochlorous acid water concentration in the electrolysis bath, a first hypochlorous acid water concentration that is a hypochlorous acid water concentration in the electrolysis bath before energization by electrode unit (140), and the increased concentration of hypochlorous acid water per unit time calculated by first calculator (510), a required energization time for achieving the target hypochlorous acid water concentration; and electrode controller (540) that performs energization in electrode unit (140) for the required energization time calculated by second calculator (512).

Abstract: Electrolyzed water spraying device (1000) of the present disclosure includes water storage tank (100), electrolysis tank (200), first feeder (128), electrode part (210), humidification tank (300), second feeder (138), third feeder (228), sprayer (310), and controller (500). In a water shortage state in which water is insufficient in electrolysis tank (200), when water and electrolysis accelerator are fed to electrolysis tank (200), controller (500) executes initial processing of generating electrolyzed water having a second concentration lower than a first concentration and feeding the electrolyzed water having the second concentration to humidification tank (300) by third feeder (228), and executes, after the initial processing, normal processing of generating electrolyzed water having the first concentration and feeding the electrolyzed water having the first concentration to humidification tank (300) by third feeder (228).
