DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention relates to a sterilizing water generator for generating hypochlorous acid by electrolyzing an aqueous solution in which a chloride is dissolved to form sterilizing water. A tank for storing an aqueous solution in which chloride is dissolved is detachably attached to the lower surface of the functional unit main body in which electric components such as are disposed, and an electrode for electrolyzing the aqueous solution from the functional unit main body into the tank, and The water supply channel of the pump device is extended. The aqueous solution used to generate hypochlorous acid may be any solution in which chloride is dissolved, and may be, for example, tap water.

Further, a handle is provided on the functional unit main body, and a cover body surrounding the electrode and the water supply channel is continuously provided on the lower surface of the functional unit main body.

That is, the sterilized water generator according to the present invention comprises:
It is configured so that the functional unit main body and the tank that can be easily separated from each other are used in an integrated manner.In use, sterilization water containing hypochlorous acid is supplied to the electrodes by supplying electricity to the electrodes. The sterilized water is generated and discharged by a pump device so that it can be used immediately.

In a state where the functional unit main body and the tank are separated from each other, the cover and the electrode can protect the electrodes and the water supply channel, and the inside of the tank becomes a simple cavity.
The inside can be easily cleaned.

As described above, the sterilizing water generator according to the present invention is a compact sterilizing generator which can be carried around and has good handling.

The concentration of hypochlorous acid in the sterilized water is set to an appropriate value depending on the intended use, and in this sterilized water generator, the predetermined value of hypochlorous acid is set by setting the energizing time to the electrode. The acid concentration can be adjusted.

Therefore, sterilized water having a hypochlorous acid concentration close to neutral pH suitable for washing hands, washing vegetables, etc., can be easily produced, and can be used at home or the like. It has become optimal.

The tank is provided with a water inlet for supplying tap water and the like, and a mesh body for containing an additive and eluted into the tank is provided in the water inlet.

This is like a so-called tea strainer,
If necessary amount of additive such as salt is stored in this and pure water or tap water is injected, the additive elutes in the tank and can be dissolved uniformly and surely in water. Generation can be performed reliably.

It is preferable that the water inlet is formed in the tank by forming a bulging portion projecting from the functional portion main body in a plan view, and provided in the bulging portion. By adopting such a configuration, water can be injected while the tank is attached to the functional portion main body without separating the tank from the functional portion main body, so that usability is further improved.

Further, as described above, it is necessary that the sterilized water has a hypochlorous acid concentration appropriate for the intended use. However, after the sterilized water having a predetermined concentration is generated, it is erroneously used in a partially used state. If the electrode is energized, electrolysis occurs even though hypochlorous acid is already at a predetermined concentration, and the concentration may be unnecessarily increased. Therefore, the sterilized water generator is provided with a water level detecting means, and the electrodes can be energized only when the water level detecting means detects that the inside of the tank is full. With this configuration, it is possible to reliably generate sterilized water without affecting the human body.

Further, the water level detecting means can be composed of an upper float switch for detecting a full state and a lower float switch for detecting an empty state.

With this configuration, after hypochlorous acid is generated,
When both switches are turned off and then the upper float switch is turned on, control can be performed so that the electrodes can be energized again.

That is, the sterilizing water generator is completely of a batch type. After generating the sterilizing water of a predetermined concentration, all of the sterilizing water is used up or transferred to another, and the tank is emptied. Unless the state is full and the initial state is established, the next sterilized water cannot be generated.

Therefore, it is possible to reliably prevent a change in the concentration of hypochlorous acid as described above, that is, an increase in the concentration of hypochlorous acid after generation.

The chlorite concentration is set anew, and sterilized water is generated again.

That is, in the present embodiment, as described above, the water level detecting means 6 is provided so that once the sterilized water of a predetermined concentration is generated, the concentration is not increased unnecessarily. If the upper and lower float switches 61 and 62 of the means 6 are turned off (the generated sterilizing water is used to empty the tank 3), and then the upper float switch 61 is not turned on. This is because the electrode 4 is again filled with water and becomes full of water.

As described above, the disinfecting water generator according to the present invention can be carried in a compact configuration, and can easily produce disinfecting water having a desired hypochlorous acid concentration in a batch system. It is extremely useful for home use and the like.
