Claims

1. It has a main body case equipped with an air intake and an air outlet, The aforementioned main body case is A gas-liquid contact section in which air is brought into contact with water containing hypochlorous acid, An air passage connecting the air intake and the air outlet via the aforementioned gas-liquid contact portion, A blower that discharges the air that has passed through the aforementioned air passage to the outside of the main body case, An electrolytic cell that electrochemically treats water to produce hypochlorous acid, A water supply section for storing water, A sterilization compartment having the aforementioned gas-liquid contact area, A first transport unit that transports water from the water supply section to the electrolytic cell, A second transport unit transports the water containing hypochlorous acid in the electrolytic cell to the disinfection section, The blower, the first transport unit and the second transport unit control unit, The water supply unit has a mechanism that stops supplying water when the water level in the water supply compartment reaches a predetermined level. The water supply section and the disinfection section are provided within the water storage container. The water storage container has a first guide section configured to guide the water in the disinfection section to the water supply section when the water level in the disinfection section reaches a predetermined level or higher. The main body case is an air purification device further comprising a third transport unit that transports water from the water supply section to the sterilization section.

2. The main body case further includes a second guide section configured to guide the water containing hypochlorous acid in the electrolytic cell from the second pre-transport channel to the second post-transport channel when the water level in the electrolytic cell rises above a predetermined level. The aforementioned second transportation section is, The electrolytic cell and the sterilization compartment are connected to each other, and the second pre-transport water channel, the second guide section, and the second post-transport water channel are connected to each other. The electrolytic cell is positioned above the sterilization compartment. The air purification device according to claim 1.

3. The water storage container has a volume capable of holding the total amount of water equal to the target water level of the water supply section, the target water level of the sterilization section, and the target water level of the electrolytic cell. The air purification device according to claim 1 or 2.

4. The water storage container has a partition wall separating the water supply section and the sterilization section. Inside the main body case, a partition plate is provided that is in contact with the partition wall and separates the inside of the main body case into the water supply compartment side and the sterilization compartment side. The first guide section is cylindrical in shape and is provided in the partition wall so as to connect the disinfection section and the water supply section. The edge of one opening in the cylindrical shape of the first guide is immersed in the water stored in the water supply compartment. The edge of the other side of the cylindrical shape of the first guide portion protrudes above the water surface of the water stored in the water storage container. The air purification device according to any one of claims 1 to 3, wherein a portion of the edge of the other side of the cylindrical shape of the first guide is set lower than the water level at which water overflows from the disinfection compartment, and when the water level in the disinfection compartment reaches a predetermined water level that is higher than the target water level of the disinfection compartment and lower than the water level at which water overflows from the disinfection compartment, water entering from the other side of the first guide flows to the one side of the cylindrical shape of the first guide.

5. The water storage container has a partition wall separating the water supply section and the sterilization section. Inside the main body case, a partition plate is provided that is in contact with the partition wall and separates the inside of the main body case into the water supply compartment side and the sterilization compartment side. The first guide section is cylindrical in shape and is provided in the partition wall so as to connect the disinfection section and the water supply section. The edge of one side of the opening in the cylindrical shape of the first guide is immersed in the water stored in the sterilization compartment. The edge of the other side of the cylindrical shape of the first guide portion protrudes above the water surface of the water stored in the water storage container. An air purification device according to any one of claims 1 to 3, wherein a part of the edge of the other side of the cylindrical shape of the first guide is set lower than the water level at which water overflows from the disinfection compartment, and when the water level in the disinfection compartment reaches a predetermined water level that is higher than the target water level of the disinfection compartment and lower than the water level at which water overflows from the disinfection compartment, water entering from one side of the first guide flows to the other side of the cylindrical shape of the first guide.
