Abstract: Chlorine ion-containing water supplied from one of water discharge pipelines of an electrolysis vessel of an apparatus for continuously forming electrolyzed water is caused to flow backwardly to one of electrode chambers and a water supply branch pipe thereof, passed through a water supply branch pipe of the other of the electrode chambers and/or a water supply pipeline at the upstream thereof and discharged through the other of the electrode chambers and from the other of the water discharge pipe lines. In this state, water in the electrolysis vessel is electrolyzed while operating the electrode of the electrode chamber in which water is caused to flow backwardly as an anode, and the electrolysis vessel and water channels at the upstream thereof are cleaned and sterilized by electrolyzed cleaning water in which hypochlorous acid is formed.

Abstract: A leaching device for electrolyzed silver comprising a pair of silver electrodes an electrolysis power source for applying a DC electrolyzing voltage between both of the electrodes, a power source control circuit for ON/OFF control of the electrolysis power source, a current control circuit for controlling the electrolyzing current flowing between both of the electrodes thereby controlling the leaching amount of silver, a polarity switching circuit for switching the polarity of the electrolyzing voltage, a driving circuit for driving the polarity switching circuit, and an abnormality sensing circuit that senses the abnormality of the silver electrode based on the change of an electric current flowing to the silver electrode.

Abstract: In an electrolysis unit for forming electrolyzed water, in which electrodes of polarity different from each other are opposed to each other and both of said electrodes are partitioned with an electrolyzing diaphragm into a pair of electrode chambers to define an electrolysis vessel, and a raw water supply portion and a pair of electrolyzed water discharging portions are disposed on the respective ends of said electrolysis vessel, a pair of water supply ports in communication with a pair of electrodes chambers in the electrolysis cell respectively are disposed independently of each other in the raw water supply portion.Chemical additives can be supplied uniformly with no requirement for additional channels. Electrolyzing operation efficiency can be improved, and unit structure and assembling work can be simplified.

Abstract: An electrolytically ionized water forming apparatus including: a plurality of electrolysis devices, each comprising an electrolysis vessel having a cathode and an anode opposed to each other and an electrolysis diaphragm partitioning the space between both of the electrodes into a cathode chamber and an anode chamber; water supply channels each disposed on one side and two discharge systems of an ionized alkaline water discharge channel in communication with the cathode chamber and an acidic water discharge channel in communication with the cathode chamber each disposed on the other side of the plurality of electrolysis devices respectively; the plurality of electrolysis devices being connected in series in a plurality of stages such that only one of the two ionized water discharge channels of the electrolysis device at a certain preceeding stage constitutes a water supply channel to the electrolysis device at the succeeding stage.

Abstract: A flow switch valve including a housing main body comprising a plurality of valve casings stacked contiguously and each having a fluid flow channel and a valve seat member, a valve member passing slidably through said valve casings and having valve bodies corresponding respectively to the valve heat members of the valve casings, a diaphragm disposed to any of the valve casings and supporting the valve member, and a signal generation device for detecting the position of the valve member in the housing main body and generating a detection signal. The valve member moves slidably depending on the change of the fluid pressure in the chamber partitioned by a diaphragm, by which valves for the fluid flow channels in the plurality of valve casings are opened or closed interlocking therewith and, at the same time, a detection signal for the position of the valve member is generated.
