Description

[Detailed Description of the Invention] The present invention relates to a continuous electrolyzed water generation device that continuously generates alkaline ionized water mainly for drinking.

In this type of continuous electrolyzed water generation device, a cathode chamber and an anode chamber are separated by a porous partition wall, electrodes are provided in each electrode chamber, and a DC voltage is applied to allow water to flow through the cathode chamber and anode chamber. A pressure type is known that causes electrolysis and electroosmosis to occur. In this type of continuous electrolyzer, water supply is controlled on the supply side in front of the electrolytic cell, and the valve on the supply side is closed when water supply is not required. Further, electrolyzed water, especially alkaline ionized water, is stored in a storage tank for use, and water is supplied from the electrolytic tank to the storage tank by the drop of water.
Therefore, only when the water level in the storage tank falls below a certain value is a signal given to the supply valve, and water is supplied to the electrolytic cell. This type requires a storage tank and a pump must be installed in the supply line from the storage tank to supply water at the desired water pressure.

This invention was developed based on the above circumstances, and the water supply port side of the electrolytic cell is connected to a pressure water source such as a tap water supply, and the pressure is used to ensure water pressure in the electrolytically generated water supply line. Electrolytically generated water can be taken out without using a storage tank or a pump, and the amount of each of the alkaline ionized water and acidic water can be regulated by controlling the pressure or flow rate to ensure efficient supply. The present invention aims to provide a continuous electrolyzed water generating device as described above.

Hereinafter, one embodiment of the present invention will be specifically described with reference to the drawings. In the figure, reference numeral 1 denotes an electrolytic cell, which has an elongated cylindrical shape and has a water supply chamber 2 at its lower end. The body is divided into the center and the outer circumference by a cylindrical porous partition wall (unglazed or otherwise functioning as an electropermeable membrane) 3, with the outer circumference serving as a cathode chamber 4 and the center serving as an anode chamber 5. Electrodes 6 and 7 are provided respectively. The bipolar chambers 4 and 5 communicate with the water supply chamber 2 at their lower ends. In addition, the cathode chamber 4 and the anode chamber 5
are connected to the outlet lines 8 and 9 at their upper ends, and the line 8 is provided with a switch means 10 such as a flow switch, and the outlet line 9 is opened and closed by a signal from the switch means 10. An on-off valve 11 such as a solenoid valve is provided. Further, the outlet side line 8 is provided with a pressure gauge or a flow meter 12,
A pressure or flow rate control valve 13 is provided in the line 9, which is controlled by the pressure value or flow rate value of this pressure gauge or flow meter 12 and whose opening degree is adjusted. Then, when the collar 14 provided at the tip of the line 8 is opened, the switch means 10 is activated.
The on-off valve 11 is opened, and the pressure gauge or flow meter 12 operates according to the pressure or flow rate.
The opening degree of the pressure or flow control valve 13 is automatically adjusted to control the pressure or flow rate on the line 9 side. When the collar 14 is closed, the switch means 10 is activated and the on-off valve 11 is closed.

In addition, the outlet side lines 8 and 9 are provided with a pipe switching valve 15 such as a motor-driven three-way switching valve,
16 is provided, and a cleaning line 17 is connected to the bypass port at both ends thereof. The cleaning line 17 is provided with a degassing tank 18 as a gas-liquid separation means and a low-pressure circulation pump 19, and a drainage line 20 that also serves as exhaust is connected to the upper part of the degassing tank 18. ing. Further, a cleaning liquid supply pump 21 is communicated with the suction side of the pump 19 via a check valve 22.

In the figure, reference numeral 23 is a motor-driven on-off valve provided in a water supply line 24 communicating with a tap water source, and reference numeral 25 is a pump for supplying chemical solutions (minerals, etc.) such as a pulse pump. , and communicates with the water supply chamber 4 via a check valve 26.

In such a configuration, when the supply lines 8 and 9 are opened by opening the collar 14, pressure water is supplied to the cathode chamber 4 and the anode chamber 5 at tap water pressure, and the pressure gauge or flow meter 12 and the pressure or By the action of the flow rate control valve 13, a supply of acidic water corresponding to the supply amount of alkaline ionized water is achieved, and under this situation, electrolysis is achieved in the electrolytic cell 1. In this case, the direct current application for electrolysis is preferably performed by a signal from the switch means 10, for example. During this time, minerals are replenished by the action of the pump 25.

By the action of an appropriate switching control means, when the on-off valve 23 is closed, the line switching valves 15 and 16 are simultaneously switched, and the cleaning line 17 is switched between the cathode chamber 4 and the anode chamber 5.
When the cleaning circuit is connected to the cathode chamber and the anode chamber, the cleaning circulation path including the cathode chamber and the anode chamber is configured to be separated from the line to which alkaline ionized water and acidic water are supplied. When the pumps 19 and 21 are driven, the cleaning liquid flows into the cleaning line 17, and is circulated together with the cleaning water through the cathode chamber 4, water supply chamber 2, and anode chamber 5. The gas generated during this washing is discharged from the degassing tank 18 to the outside via the drainage line 20. Then, when the cleaning is finished (it is advisable to set the time using a timer etc.), the pump 21 is stopped and the on-off valve 23 is opened, and new water is supplied for cleaning via the water supply chamber 2 and the anode chamber 5. enters the line 17 and is partially discharged into the drainage line 20 via the degassing tank 18,
The remainder flows into the cathode chamber 4 via the pump 19 and gradually washes the inside of the electrolytic cell 1 with water. Once the inside of the electrolytic cell 1 has become clean in this way, the cathode chamber and anode chamber can be switched to the supply destination side of the outlet lines 8 and 9 by switching the pipe switching valves 15 and 16, and then the next electrolysis can be started. and is set to normal water production conditions by electroosmosis.

In the above embodiment, a pressure gauge or a flow meter 12 was provided in the supply line 8, and a correspondingly controlled pressure or flow rate control valve 13 was provided in the outlet line 9, but this could be reversed. Alternatively, both may be provided with pressure gauges or flow meters for controlling the pressure or flow rate control valve of the other, respectively, so that the pressure or flow rate can be controlled mutually.

As described in detail above, the present invention provides a pressure gauge, a flow meter, and means for controlling pressure or flow rate in the outlet lines communicating with the cathode chamber and the anode chamber, respectively, so as to adjust the pressure or flow rate of at least one of them. Since the pressure or flow rate of at least the other one is controlled, there is no waste in the amount of water supplied, and moreover, there is a practical effect that water can be supplied under pressure using tap water pressure.
