DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a continuous electrolyzed water generator such as an alkali ion water purifier for purifying raw water (for example, tap water) and electrolyzing to generate electrolyzed water. Specifically, in order to remove (peel) the electrode (cathode and anode) of the electrolytic cell or the scale (calcium content of raw water and calcium content of the calcium preparation added with chemicals) etc. of the diaphragm (diaphragm and diaphragm holding resin frame), etc. It relates to the improvement of the backwashing performed.

[0002]

2. Description of the Related Art Conventionally, a method for cleaning a continuous electrolyzed water generator by reverse electric power is disclosed in, for example, Japanese Utility Model Publication No. 2-7675. For example, as disclosed in Japanese Patent Application Laid-Open No. 5-293470, there is a technique in which residual water (full state) in an electrolytic cell is maintained.

[0003]

However, in the conventional reverse-current cleaning method, since only the electrical removal (peeling) is performed, the reverse-current cleaning time is required to some extent.

The present invention has been made in view of the above-mentioned problems of the prior art, and it is an object of the present invention to provide an electrode or a diaphragm for an electrolytic cell with a short reverse-current cleaning time. It is an object of the present invention to provide a continuous electrolytic water generator that can completely remove (peel) scales and the like.

In order to achieve the above object, in a continuous electrolytic water generator according to the present invention, a raw water supply section, a water purification section, a flow rate detection section, a chemical addition section,
In a continuous electrolytic water generator comprising an electrolytic cell, a drain valve mechanism, an electrolytic water spouting section, an electric circuit section, and a water channel section,
The reverse electric cleaning performed for the purpose of removing (peeling) the scale or the like of the electrode or the diaphragm of the electrolytic cell is performed by mechanically removing the electrolytic cell (peeling) by inverting the voltage applied to the electrode of the electrolytic cell. And mechanical removal (peeling) performed by oscillating the surface of the electrode or residual water. Also, in a continuous electrolytic water generator comprising a raw water supply section, a water purification section, a flow rate detection section, a chemical addition section, an electrolytic tank, a drain valve mechanism, an electrolytic water discharge section, and an electric circuit section. During normal electrolysis, the drain valve mechanism is closed, and after stopping water (stopping electrolysis) or during backwashing, the electrode surface of the electrolytic cell or the surface of the residual water is swung to mechanically scale the electrode or diaphragm. In order to promote removal (peeling), the opening operation is interrupted at least once into the drain valve mechanism that is closed, and the drain valve mechanism is opened during draining or standby.

Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a schematic diagram of a continuous electrolytic water generator 10 according to one embodiment of the present invention. The continuous electrolyzed water generator 10 (hereinafter, referred to as the main unit 10) according to one embodiment of the present invention includes:
Raw water supply unit 20 (water supply hose etc.) and water purification unit 30 (water purification cartridge composed of activated carbon 31, hollow fiber membrane 32, etc.)
, A flow detecting unit 40 (impeller flow sensor or the like), a drug adding unit 50 (for example, adding a calcium preparation such as calcium lactate), and an electrolytic cell 60 (an electrode in which one is a cathode or an anode) 61, diaphragm 6 having diaphragm-holding resin frame
2, an electrolytic cell case 63), a drain valve mechanism 70 (a normally open electromagnetic drain valve or the like), and an electrolytic water spouting section 80 (a spouting pipe 81 or the like for the cathodic water spout during normal electrolysis, such as an anode during normal electrolysis). In the case of water spouting, an acidic water hose 82 and the like, and an electric circuit unit 90 (electrolytic power or electrolytic current consumed in the electrolytic cell, and a power transformer 92 (supplied with electric power or current consumed by the microcomputer-type electric control device and the like) In the case of performing pulse control, a switching power supply device may be used.), A microcomputer-type electric control device 91 including a printed wiring board unit on which electric and electronic components and the like are mounted, and a water channel portion 100 (a resin water channel block, a resin pipe, and the like). And consisting of

[0007] A series of operating principles of the instrument 10 will be described. During standby when raw water is not passed through the device 10, the drain valve mechanism 70
To open operation (power failure). For example, by operating a stopcock,
When the raw water is passed through the main unit 10, the water channel 10 through which the water flows
The flow detector 40 connected (connected) to 0 transmits a certain signal according to the flow at that time. Normally, electrolysis is started by the signal. During the normal electrolysis, the drain valve mechanism 70 is closed (energized). For example, by operating a stopcock, the device 10
When the raw water is stopped, the flow detecting unit 40 connected (coupled) to the water channel unit 100 transmits a signal corresponding to the flow rate at that time. The signal is used to stop the normal electrolysis (the drain valve mechanism 70 continues the closing operation (energization)). Immediately after water stoppage (electrolysis stop) or after a while, it may be after a while, but after water stoppage (electrolysis stop), the surface of the residual water in the electrolytic cell 60 is rocked to mechanically move the electrode 61 (cathode or anode) or In order to promote removal (peeling) of the scale or the like of the diaphragm 62, the drain valve mechanism 70 that is closed (energized) is operated by interrupting the opening operation (power failure) (for example, for one second) at least once. Then, the reverse power cleaning is started. During the backwashing, a closing operation (energization) is performed to oscillate the surface of the residual water in the electrolytic cell 60 to mechanically promote the removal (peeling) of the scale of the electrode 61 (cathode or anode) or the diaphragm 62. Opening of the drain valve mechanism 70 (power failure)
(For example, for 1 second) is interrupted once or more and activated. One of the mechanical factors that fluctuates the surface of the residual water is:
Negative pressure is generated in the electrolytic cell 60 by operating the drain valve mechanism 70 that is closed (energized) at least once by opening (power failure) (for example, one second). This is because water near the electrode 61 (cathode or anode) moves up and down, for example, due to the pressure fluctuation such as the negative pressure.
Another is that vibration is generated by repeating the opening and closing operations of the drain valve mechanism 70. The vibration is applied to the electrolytic cell 60 (or the water purification unit 3) connected (connected) to the water channel unit 100.
This is because the water near the electrode 61 (cathode or anode) moves up and down, for example, to the components 61 and other components.
In the present apparatus 10, as described above, the mechanical removal (peeling) is added to the electrical removal (peeling), so that the reverse electric cleaning time can be reduced by 50%. When the backwashing is completed, the drain valve mechanism 70 is opened (power failure), and the residual water in the electrolytic cell 60 is drained. After draining, while the raw water is not flowing through the main unit 10, the drain valve mechanism 70 is kept open (power failure).

Although the preferred embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and many combinations and modifications can be made without departing from the spirit of the invention. Of course it can be done. In the continuous electrolyzed water generator of the present invention, the drain valve mechanism is a normally-open electromagnetic drain valve, but may be, for example, a normally-closed electromagnetic drain valve. If the cost is allowed, for example, a vibrator (vibration generator) or the like may be provided (attached) in the continuous electrolyzed water generator (electrolyzer) to promote mechanical removal (peeling).

[0009]

According to the continuous electrolytic water generator of the present invention, mechanical removal (peeling) is added to electrical removal (peeling), whereby the effect of shortening the time for backwashing can be achieved.
