  Hereinafter, an electrolyzed water generation system of each embodiment and an electrolyzed water generation device used therein will be described with reference to the drawings. In the following embodiments, portions denoted by the same reference numerals have the same function as each other unless otherwise specified, even if there is a slight difference in shape in the drawings. I do.

  In the present embodiment, electrolyzed water generator 100 is an ozone water generator that generates ozone water as electrolyzed water. Since ozone water is effective for sterilization or decomposition of organic substances, it is used in the field of water treatment, food, or medicine, has low residual properties, and has the advantage of not generating by-products. ing.

  In this specification, the X direction in FIG. 1 is a direction along the flow path of water, and is referred to as a water flow direction. As shown in FIG. 1, the electrolyzed water generator 100 has a rectangular parallelepiped shape in which the X direction is the longitudinal direction. The Y direction in FIG. 1 is a direction crossing the flow path of water and is called a width direction. The Y direction is a direction along a horizontal plane. The Z direction in FIG. 1 is a direction in which the electrode and the conductive film are stacked, and is called a stacking direction. In FIG. 1, the vertical direction is shown as the Z direction in a state where the lid 2 of the electrolyzed water generation device 100 is positioned on the upper side. The X direction, the Y direction, and the Z direction are not limited to the combination of the directions shown in FIG. 1, and the electrolyzed water generation device 100 may be provided in any posture.

  However, it is desirable that the electrolyzed water generating apparatus 100 of the embodiment be incorporated into another apparatus in such a manner that its flow path extends along the vertical direction. More specifically, it is preferable that the electrolyzed water generation device 100 be incorporated into another device in such a manner that the inflow port Fin faces downward and the outflow port Fout faces upward. In other words, the posture of the electrolyzed water generation device 100 is preferably set so that water flows upward from below. The reason is that it is preferable to quickly separate ozone from the surface of the anode A before the ozone generated on the surface of the anode A grows into bubbles. That is, when the inflow port Fin faces downward and the outflow port faces upward, ozone is quickly separated from the surface of the anode A by buoyancy. According to this, the ozone is prevented from remaining in a bubble state, and is easily dissolved in water, so that the efficiency of generating ozone water is improved. However, the electrolyzed water generation device 100 may be incorporated in another device in any posture other than the posture in which the flow path extends along the vertical direction.
