In addition, although this embodiment demonstrates the structure which is a mist production | generation apparatus which atomizes (mist-forms) and sprays the electrolyzed water electrolyzed by the electrolysis apparatus 1, the structure and use of the electrolysis apparatus 1 are restricted to this. It is not a thing. For example, the structure which uses electrolytic water for uses, such as drinking, space humidification, washing | cleaning / washing | cleaning / sterilization, may be sufficient.

As shown in FIGS. 1 and 2, the electrolysis apparatus 1 includes an electrolytic cell 10 and a main body 11 that is detachably attached to the electrolytic cell 10 on the upper surface side of the electrolytic cell 10. The main body 11 includes an electrode unit 20, a power feeding unit 30, a stirring unit 40, a spraying unit 50, and a control unit 60.

The electrolytic cell 10 is a container for storing water to be subjected to electrolytic treatment, and has a shape in which a substantially cylindrical bottom surface is closed.

The power feeding unit 30 extends from the main body 11 to a position facing the bottom surface of the electrolytic cell 10 along the central axis of the substantially cylindrical electrolytic cell 10. Note that the upper end portion of the power supply unit 30 is connected to a spray unit 50 provided on the upper surface of the main body unit 11, and the electrode unit 20 is attached to the lower end portion of the power supply unit 30.

The electrode unit 20 is a multi-cylindrical electrode in which the first electrode 21 and the second electrode 22 are alternately arranged concentrically at a predetermined interval, and between the first electrode 21 and the second electrode 22. By applying a voltage via the first power supply unit 32 and the second power supply unit 33 provided in the power supply unit 30, the water between these two electrodes is subjected to electrolytic treatment. Details of the electrode unit 20 will be described later.

As the first electrode 21, for example, an ion adsorption / desorption electrode having a characteristic capable of reversibly adsorbing and releasing ions can be used. As the ion adsorption electrode, for example, an electrode that forms an electric double layer on the surface by adsorbing ions in a solution can be used. This electric double layer is constituted by the surface charge of the conductive material and ions attracted to the surface charge. The ions constituting the electric double layer have a charge of the opposite polarity to the surface charge of the conductive material adsorbing the ions. For example, when the surface charge is a positive charge, an anion is adsorbed, and when the surface charge is a negative charge, a cation is adsorbed.

It arrange | positions so that it may extend | stretch in any direction. The screw 44 is attached to the other end side of the shaft 43.

As a result, the rotational driving force of the motor 41 is transmitted to the shaft 43 through the gear 42, the shaft 43 and the screw 44 rotate, and the water in the electrolytic cell 10 is discharged from the screw 44 in the axial direction of the shaft 43 to perform electrolysis. Stir in the bath 10.

The spray unit 50 is attached to the upper end of the power supply unit 30, and atomizes (mists) the electrolyzed water that has been electrolyzed by the electrode unit 20 that is supplied through the water supply pipe 31. Spray outside.
