Abstract

PROBLEM TO BE SOLVED: To improve cleaning effect in an electrolytic cell and a pipe line by passing a city water through the electrolytic cell and the pipe line in a state of stopping the charge of an electrolytic assistant and the impressing of voltage for electrolysis to discharge the elecholytic assistant remaining in the inside part in the generation of an ionized water by the electrolysis of water. SOLUTION: The city water from a water charging opening 2 flows in the electrolytic cell 9 and simultaneously a salt water stored in a salt water tank 10 is fed to the electrolytic cell 9 with a salt water pump 11 and joins the city water. The city water in which the salt water is charged is electrolyzed with electrodes 12 and 13, an alkaline water and an acidic water are discharged from a discharging opening 3 and a discharging opening 4, respectively. In such a case, when a salt water discharging switch is fumed to 'on' on the operation waiting, the city water is charged with a clean water valve 8 opened, next after the set time (about 10sec) in a timer elapsed, the clean water valve 8 is closed and the operation returns to the waiting state. During the period, only the city water is passed through the electrolytic cell or the pipe line to wash out the remaining salt water.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ion water generator for electrolyzing water to generate ion water, and particularly to continuously supplying acidic water or alkaline water from tap water to which an electrolysis aid such as saline is added. The present invention relates to an ionized water generator.

[0002]

2. Description of the Related Art In the conventional ion water generator described above, when the operation is stopped, the supply of the electrolysis aid is stopped and the supply of tap water is stopped at the same time.

[0003]

However, in the conventional ion water generator that stops the supply of the electrolysis aid and tap water in synchronism, the electrolysis aid remains inside the electrolytic cell and the pipes, and the There was a risk of corroding them. The object of the present invention is to
It is to prevent the electrolysis auxiliary agent from remaining when the operation of the ionized water generator is stopped.

[0004]

To solve the above problems, tap water is supplied to an electrolytic cell while injecting the electrolysis aid of the present invention, and a DC voltage is applied to electrodes installed in the electrolytic cell. Thereby, in an ion water generator that electrolyzes water in the electrolytic cell to continuously generate ion water, tap water is electrolyzed in a state where injection of the electrolysis aid and voltage application to the electrodes are stopped. A means for causing the electrolytic solution to flow through the tank and the pipe and discharging the electrolysis aid remaining inside thereof is provided.

According to such means, since only the tap water can be supplied to clean the inside of the ion water generator, it is possible to reliably prevent the electrolysis auxiliary agent from remaining. Further, in that case, by providing a timer means for allowing tap water to flow for a certain period of time by the ON signal of the electrolysis aid discharge switch, tap water can be supplied for a sufficient and sufficient time for discharging the residual electrolysis aid, It is possible to avoid waste of water due to the flow of water and insufficient cleaning due to insufficient flow of water.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention in an ion water generator using saline as an electrolysis aid will be described below with reference to FIGS. First, FIG. 2 is a front view showing the appearance of the ion water generator. A water supply port 2 for taking in tap water from a water tap (not shown) is provided in the upper part of the main body 1, and the generated alkaline water and acidic water are in the lower part. An alkaline water discharge port 3 and an acidic water discharge port 4 for discharging each are provided. Then, on the front surface of the main body 1, a start switch 5 for starting the operation of the ion water generator, a stop switch 6 for stopping the operation, and a discharge switch 7 for discharging the remaining salt solution (electrolysis auxiliary agent) are arranged in a vertical line. Has been done.

FIG. 3 shows the internal structure of the ion water generator. In FIG. 3, tap water entered from the water inlet 2 enters the electrolytic cell 9 via a water valve (solenoid valve) 8 as shown by an arrow A. At the same time, the saline solution stored in the saline solution tank 10 is sent to the electrolytic cell 9 by the saline solution pump 11 as shown by the arrow B, and merges with the tap water at the inlet. Electrodes 12 and 13 are installed in the electrolytic cell 9, and tap water into which salt water is injected is electrolyzed by the electric power applied to the electrodes 12 and 13 from the DC power source 14, so that the vicinity of the minus electrode 12 is alkaline. Water and acidic water are generated near the positive electrode 13. Then, the alkaline water is discharged from the alkaline water discharge port 3 as shown by an arrow C, and the acidic water is discharged from the acidic water discharge port 4 as shown by an arrow D.

FIG. 1 is a control block diagram of the above-mentioned ion water generator. The control unit 15 includes a start switch 5 and a stop switch 6.
Accept the signal from the water supply valve 8, salt water pump 11
And the power supply 14 are controlled to be turned on and off. In addition, the timer 16 receives a signal from the saline discharge switch 7.
The water supply valve 8 is on / off controlled while counting the time.

FIG. 4 is a flow chart showing a control program of the control unit 15. In FIG. 4, it is checked whether there is an input from the saline discharge switch 7 while the operation is on standby (step S1), and if there is no input, it is checked whether there is an input from the start switch 5 (step S2). Then, if there is an input, the water valve 8 is opened (step S3), and the saline pump 11 is started in synchronization with it (step S3).
4) Also, in synchronization with this, a voltage is applied to the electrodes 12 and 13 to start electrolysis (step S5). After that, the input from the stop switch 6 is checked (step S
6), if there is an input, close the water valve 8 (step S7),
The saline solution pump 11 is stopped in synchronization therewith (step S
8), and in synchronism with this, electrolysis is stopped (step S9).

On the other hand, when there is an input from the saline discharge switch 7 in step S1 during standby of operation, the tap water valve 8 is opened to supply tap water (step S10), and then the timer 16
To start counting the time for 10 seconds, for example (step S11). Then, it is checked whether or not the timer 16 has ended (step S12), and when it has ended, the water supply valve 8 is closed (step S13), and the standby state is restored.
During this time, tap water is discharged from both the alkaline water discharge port 3 and the acidic water discharge port 4 while washing the residual saline solution by flowing through the inside of the electrolytic cell 9 and the pipe.
