In general, a water purifier filters and purifies oxides, heavy metals, dust, and debris contained in water using a filter including activated carbon, an ion membrane, and the like. Various water purifiers are used.

In the early water purifiers, activated carbon was stacked in purified water tanks and water was poured into the purified water tanks to allow for natural purification.In this way, purified water was supplied through supply valves. Or there is a problem that the water purified by being stacked in the water purification tank is decayed.

Reverse osmosis type water purifiers have been widely used to purify water while moving through a plurality of filter members such as pre-filtered filter, pre-treated activated carbon filter, reverse osmosis membrane filter and post-treated activated carbon filter.

In recent years, the water filtered by the water purifier is electrolyzed again using an electrolytic cell, and an ionizer which uses alkaline water as drinking water and acidic water as beauty water has been widely spotlighted. (Korea Patent Publication No. 10-0484921) Reference)

On the other hand, in a device for producing product water using tap water as a raw water, such as a water purifier or an ionizer, a filter filled with activated carbon is used to remove residual chlorine contained in the tap water.

Such activated carbon filters can remove residual chlorine and remove organic substances in water through physical and chemical adsorption reactions.But microorganisms in tap water are concentrated because microorganisms are accumulated and concentrated inside activated carbon filters. When entering the activated carbon filter, there was a problem that the organic matter accumulated in the activated carbon filter grew rapidly.

However, since the silver ion is continuously eluted from the electrode when the electrode for the silver electrolytic bath is used for a long time, the phenomenon that the width and thickness of the electrode gradually decreases as shown in FIG. 1A.

In this way, since the opposite area of the electrode is reduced and the voltage applied to the electrode area is increased, high heat is generated in the voltage applying part 12 of the electrode, and black leakage occurs due to heat generation of the voltage applying part 12. There was a problem that causes safety accidents such as electric shock and fire.

Accordingly, the present invention has been made to solve the above problems, an object of the present invention is to form a voltage applying portion of the silver electrolytic bath electrode plate so as to be deflected with respect to the center line of the electrode plate, so that the voltage applying portion to cross each other in the silver electrolytic bath. By arranging the electrode plate, it is possible to prevent the voltage application part from overheating due to the loss of the silver electrode due to the long time operation of the silver electrolytic bath, and the electrode for the silver electrolytic bath and the silver electrolytic bath which can improve the workability according to the wire connection work. In providing.
