The ozone sterilization water purification operation by the ozone sterilization water purification system of the present invention configured as described above will be described with reference to FIGS. 1 and 2.

When power is applied, the central processing unit 19 turns on the power indicator of the control panel 18 and searches for the switch unit 18d.

When the user presses the drinking water button of the switch unit 18d in order to receive drinking water, the central processing unit 19 detects this and turns on the drinking water indicator of the control panel 18. Output a control signal.

That is, the solenoid valve control signal is output to control the solenoid driver 24, and the solenoid driver 24 receives the control signal to drive the solenoid valve to open the first solenoid valve 2 to open the second solenoid valve 15. ) Also opens, and the third solenoid valve 16 closes.

Then, the ozone generator control signal is output to operate the ozone generator 7 through the ozone generator driver 23.

The ozone generator 7 generates ozone gas by an ozone generating electrode (see application patent 94-15272, June 29, 1994) that generates ozone by corona discharge upon application of high pressure, and the ozone generator composition section 7 It is a relay circuit which supplies (or cuts off) power to the generator 7.

On the other hand, the central processing unit 19 outputs a motor pump control signal, and the motor pump driver 25 drives the motor pump 10 in response to the control signal.

The motor pump drive unit 25 is a relay circuit for controlling supply (or interruption) of power supplied to the motor pump 10 from the power supply unit.

In this way, when the valves are opened and the motor pump 10 is operated, water flows in each pipe, and the valve 4b of the flow pipe 4 opens the water supply path while compressing the spring 4c with water pressure, and at the same time, the flow The switch 4a senses the flow of water and turns it on.

At this time, foreign matters of the water supplied to the raw water inlet are removed from the pretreatment filter (1), and the raw water passed through the pretreatment filter (1) is decompressed to maintain a constant water pressure by the pressure reducing valve (2), and then the open solenoid valve (3). Is supplied to the flow pipe (4).

The pressure reducing valve 2 is installed to prevent variations in the mixing concentration and efficiency of the ozone gas, and consequently the sterilization treatment capacity according to the water supply environment (water pressure fluctuation according to time zone, actual height, etc.), and passes through the pressure reducing valve 2. Water pressure is one example, about 1.5kg / cm 2 -2.0kg / cm 2.

When the flow switch 4a is turned on by the flow of raw water passing through the flow pipe 4 as described above, the detected signal is supplied to the central processing unit 19, and the ozone generator 7 as described above. When the ozone generator 7 is activated, the ozone generator 7 generates ozone gas by the high pressure discharge of the dry air and the ozone generator supplied from the dehumidifier 8 through the blower tube 9, and the generated ozone gas O 3 is an ozone supply pipe ( 6) is supplied to the venturi (5) side.

At this time, the air sucked into the intake hole (8a) from the dehumidifier (8) is dehumidified by the dehumidifier (8b), is provided to the ozone generator (7) through the blower tube (9) as air in the dry state to the moisture component This prevents the ozone generation efficiency from dropping.

On the other hand, the check valve 6a inside the ozone supply pipe 6 prevents water from flowing back to the ozone supply pipe 6-the ozone generator 7 side, and the ozone gas flows toward the venturi 5 through the check valve 6a. Supply it.

In addition, the venturi 5 automatically inputs and mixes the ozone gas generated by the ozone generator 7 to water to activate the oxidizing action. The action of the venturi 5 causes ozone gas to be dissolved in water and ozone water. Is generated.

Because ozone water contains a large amount of ozone in water, drinking it as drinking water activates cellular tissues in the body to promote metabolism, relieve oxidation and deficiency, remove unnecessary lumps of skin tissue, It is known to report the appropriate amount of cholester (sugar) and uric acid.

In addition, ozone is 3600 times faster than chlorine and has a strong sterilizing power, and is known to be able to rupture the cell membranes of viruses, bacteria, and E. coli, and to prevent the formation and reproduction of bacteria.

In addition, ozone is known to oxidize various heavy metals dissolved in water, synthetic detergents, and organic compounds such as trihalmethane, phenol, ammonia nitrogen, and the like to make solids that are harmless to the human body.

Ozone water has a characteristic smell of ozone, and the oxidizing, sterilizing, disinfecting and deodorizing of ozone contains ozone water, washing vegetables, fruits and vegetables, disinfecting kitchen equipment, treating various skin diseases such as athlete's foot and eczema, and draining sinks. It is used to remove unpleasant odors in bathrooms and bathrooms, and is known to create a sanitary and comfortable living environment and health.

Therefore, the ozone water generated as described above is supplied to the drinking water supply pipe 12 and the external water supply pipe 13 via the motor pump 10.

At this time, the ozone water stored without use is recovered to the flow pipe 4 side via the recovery pipe 11 and the check valve 11a.

As described above, since the user presses the drinking water switch in the switch unit 18b of the control panel 18, the second solenoid valve 15 is open and the third solenoid valve 16 is closed. The ozone water supplied to the water supply pipe 13 does not pass through the third solenoid valve 16.

However, the ozone water supplied to the drinking water supply pipe 12 is subjected to a three-stage post-treatment filter 14 to remove ozone odor components and chlorine components by means of activated carbon 4a, ions, microfilters, etc. The purified water is output as drinking water, and the drinking water which has passed through the post-treatment filter is drained through the open second solenoid valve 15 to the drain 17.

Therefore, the drain port 17 is to drain the clean water (sterilization, purification) treated water.

As another case, when the user presses the external water switch in the switch unit 18b on the control panel 18, the central processing unit 19 detects this, and the second solenoid valve 15 is closed and the third solenoid valve ( 16) will open.

In this way, the ozone water supplied to the drinking water supply pipe 12 is blocked by not passing through the aftertreatment filter 14 or the second solenoid valve 15, and the ozone water supplied to the external water supply pipe 13 is blocked by the third solenoid valve 16. It passes through and drains to the drain 17.

That is, the external water is discharged to the drain 17, and thus the ozone water discharged to the drain 17 is used for purposes other than drinking water. For example, washing vegetables, fruits, vegetables, etc., disinfecting kitchen appliances, sinks, Used directly to clean the bathroom.

This operation is continued by the control of the central processing unit 19 while the flow of water generated when the ozone water is used on the drain port 17 side is detected (switched on) by the flow switch 4a, and when the use of the water is stopped. In the case of a single stage, the central processing unit 19 controls each of the driving units 23, 24, 25 by the detection result (switching off) of the flow switch 4a, so that the ozone generator 7 and the solenoid valve 3 (15) (16) and motor pump (10) shut off the power supply to protect the equipment from overload and stop the ozone water generation and supply operation.

On the other hand, while supplying ozone water as described above, when the user presses the drinking water switch or the external water switch on the control panel 18 again, the central processing unit 19 controls each of the driving units 23, 24, 25. The ozone generator 7, the solenoid valves 3, 15, 16 and the motor pump 10 are turned off to stop the ozone water generation and supply operation. At this time, the central processing unit 19 is a timer. The off delay time is secured using (20), and each load is stopped after this off delay time has elapsed.

For example, when the drinking water switch or the external water switch is pressed again, the central processing unit 19 first switches off the solenoid valve to shut off the water supply, and the time of the timer 20 is searched for about 5 seconds as the off delay time. When 5 seconds have elapsed since the delay time is secured, the power of the motor pump 10 and the ozone generator 7 is turned off while the display of the corresponding switch on the control panel 18 is turned off.

As described above, when the flow of water disappears, the elastic force of the spring 4c in the flow pipe 4 restores the valve 4b to block the water supply path.

In addition, as described above, when the motor pump 10 operates under the control of the central processing unit 19, the service life of the motor pump 10 is calculated and displayed on the display unit 18b when it is time to replace the motor.

The life of the motor pump 10 is stored in the memory 21. For example, when the life of the motor pump 10 of a certain model is 3000 hours, the central processing unit 19 is operated every time the motor pump 10 is operated. The pump operating time is counted and accumulated, and the accumulated operating time is compared with 3000 hours stored in the memory 21, and when the 3000 hours is reached, a message informing the motor pump replacement is displayed on the display unit 18b. In addition, the alarm-buzzer 18a on the control panel 18 is sounded.

The memory 21 also stores an operating time.

For example, one operation time is stored in the memory 21 for 30 minutes, and as described above, when the user operates the device to obtain external water or drinking water, the operation time is determined by a timer in the central processing unit 19. Search by using (20), if 30 minutes are detected by the timer 20, the central processing unit 19 is to stop the operation of each drive unit.

On the other hand, as described above, the ozone sterilizing water purification system of the present invention can be connected to a water supply source to carry out water purification, as well as sterilizing it as ozone gas even if drinking water, industrial water, or groundwater which can be used as living water is used as a water supply source. Because it sterilizes, it can guarantee the use of drinking water, living water, ground water as well as water, and the water filled in the swimming pool can also act as a device for supplying ozone sterilized water.

As described above, the ozone sterilizing water purification system of the present invention dissolves ozone gas in water to make ozone water, and by using the ozone water for external or drinking water, it is effective to ensure a sanitary and clean water supply environment. .

In addition, the ozone sterilization water purification system of the present invention has an effect of facilitating washing and disinfection of various kitchen appliances, maintaining cleanliness, and implementing a hygienic environment by utilizing ozone-specific effects.

In addition, the ozone sterilizing water purification system of the present invention allows ozone water to be used as drinking water by passing through a filter, thereby providing a more clean and hygienic supply of drinking water.

In addition, the ozone sterilization water purification system of the present invention is convenient because the operation of ozone water purification is automatically controlled according to the detection of the flow switch, and it is convenient to automate the operation of the water purifier, and the water supply path in each pipe is controlled by using an electronic valve-solenoid valve. It is convenient because it can be controlled by one touch method, and it can improve the reliability of the device by displaying the replacement time by self-diagnosing the life of the motor pump.

In addition, the ozone sterilizing water purification system of the present invention can supply more clean and hygienic water through pre-treatment and post-treatment filtering, and can ensure sanitary environment through multi-stage filtering, and drainage of drinking water and external water into one drain It is possible to further improve the convenience of using the device because it is possible to supply necessary water by integrating it with a simple switch operation.

In addition, since the automatic pressure adjustment is performed by using a pressure reducing valve, the phenomenon of ozone sterilization treatment ability can be prevented from being changed according to the water supply environment-water pressure-, thereby improving the quality and reliability of the device.
