outlet ports

111 and 112 may be coaxially disposed with each other. The inner space of the first housing 110 is a space where hydrogen ions formed in the cathode electrode 114 are mixed with water.

The OH-ion generated at 114 generates ions on the surface of the ions with the cation, thereby reducing scale generation on the surface of the cathode electrode 114.

The solid polymer electrolyte membrane 150 transfers hydrogen ions generated by an electrolysis reaction between the cathode electrode 114 and the anode electrode 124.

Meanwhile, the ozone filter 300 illustrated in FIG. 3 may be installed on a flow path connected to the oxidation water discharge port 122 formed in the chamber of the anode electrode 124 of the electrolysis unit 100. The ozone filter 300 is installed to remove ozone, and an oxidation water discharge coke 410 may be installed at a rear end thereof.

Hereinafter, the operation of the hydrogen water group according to the present embodiment will be described.

Hydrogen water may be circulated through the water stored in the water reservoir 200 to store the hydrogen water to extract and drink it, or to generate hydrogen while extracting the water in the water reservoir to immediately drink. In this case, the ozone filter 300 installed in the electrolysis unit 100 and the rear end thereof may be periodically replaced to preserve performance efficiency after a predetermined time. In addition, a cleaning operation may be performed to wash / sterilize the hydrogen water flow channel and the water reservoir 200 in order to improve water quality.

For example, the hydrogen water group may operate in a circulation mode, an extraction mode, and a direct water mode.

Referring to FIG. 3, in the circulation mode, when the hydrogen water generation button is pressed in the operation button 13, the first and third solenoid valves S1 and S3 are operated to open, and a delay of 0.5 seconds is set. The first and second pumps P1 and P2 may be driven and the electrolysis unit 100 may be operated. That is, the first solenoid valve S1 is opened to pass hydrogen water generated in the electrolysis unit 100, and the second solenoid valve S2 maintains a closed state. When the third solenoid valve S3 is opened, the generated hydrogen water may be supplied to the water reservoir 200 by the pressure from the first pump P1 or the second pump P2. In this case, the electrolysis unit 100 may operate for 2 to 3 minutes. In addition, the hydrogen generation and circulation time can be added or subtracted according to the number of water so as to prevent excessive increase in the dissolved hydrogen amount by checking the pH value. In this case, the circulation time may vary according to the amount of water stored in the water reservoir 200. For example, a water level sensor for detecting the water level of the water reservoir 200 is installed, and the detection level of the water level sensor is 'W / L'. If it is 1 ', it can be set as warning, 2.5 minutes when the sensing level is' W / L 2', and 3 minutes when the sensing level is' W / L 3 'and' W / L 4 '. It is preferable that the water level sensor installed in the water reservoir 200 can detect and distinguish the water level in at least four steps.

In the extraction mode, when the water supply button is pressed in the operation button 13, the electrolysis unit 100 is maintained in the off state while the first pump P1 is turned off, and the first solenoid valve S1 is also closed. Then, after the delay of 0.5 seconds, the hydrogen water stored in the water reservoir 200 is discharged by the operation of the second pump (P2), wherein the third solenoid valve (S3) is opened together with the second solenoid valve (S2) May be withdrawn from the coke 17. In this case, the operation time of the second pump P2 may be set to, for example, 10 seconds on the basis of 200 ml extraction, and may be set to 25 seconds when the 500 ml is extracted. When the water level of the water reservoir 200 is sensed below the sensing level 'W / L 1', the water extraction operation may be stopped.

In the direct water mode, the hydrogen water generation button and the water supply button of the operation button 13 may be simultaneously pressed to enter the direct water mode. As such, when entering the direct water mode, the user may press the water supply button to start the water supply operation. At this time, the first and second pumps P1 and P2 and the electrolysis unit 100 circulate for 5 seconds after a delay of 0.5 seconds after the first and third solenoid valves S1 and S3 are operated and opened. It can work the same as the mode. Alternatively, the second pump P2 may be operated after a 0.5 second delay after the first pump P1, the electrolysis unit 100, and the first to third solenoid valves S1, S2, and S3 are operated. The operation time of the second pump P2 may be continued while the water supply button is pressed. On the other hand, when the detection level of the water level sensor is 'W / L 1', the first pump (P1) is operated until the detection of idle for 5 seconds or more to clean the flow path and the electrolysis unit 100 while washing the water inside the hydrogen equipment Can get out completely.

In addition to the above three modes, even if the power button is not pressed separately, if no control signal is input for more than 10 seconds, the front display 12 may be turned off and then enter the standby mode.

In addition, the operation button 13 is provided with a cleaning button, it can be pressed into the cleaning and sterilization mode. Sterilization mode is to form ozone water using the ozone generated from the electrolysis unit 100, and sterilize the inner flow path and the water reservoir 200 using the sterilization water, the related technology is the applicant's registered patent It is described in detail in 10-1198652.

On the other hand, when the drain 15 is not provided with a separate drain port, the drain 15 is also provided with a water level sensor, and as shown in FIG. 3, the level of the drain unit 15 has a predetermined detection level 'W / In the case of L 5 ′, the front display 12 may warn of discarding the water contained in the drain 15, or may output a warning sound using a speaker unit or the like not shown.

Another feature of the present invention is that the water stored in the water reservoir 200 is the surface of the cathode electrode 114 so that hydrogen ions attached to the surface of the cathode electrode 114 installed in the electrolysis unit 100 can be more easily mixed with water. The inflow port 111 and the outflow port 112 are arranged to be coaxial so as to move while scratching.

According to such a configuration, the flow of water is formed in the chamber in which the cathode electrode 114 is formed, toward the chamber in which the anode electrode 124 is formed, so that hydrogen is generated in the chamber in which the cathode electrode 114 is formed, and the anode electrode 124 is formed. Oxidized water is generated in the formed chamber. In this case, in order to improve the dissolution rate and the generation force during hydrogen generation, a fast flow rate and a high pressure are required in the chamber in which the cathode electrode 114 is formed. As such, the water pressure applied to the inflow and

outflow ports

111 and 112 may be applied through the first and second pumps P1 and P2. In addition, another reason for the flow of water from the cathode electrode 114 to the anode electrode 124 is that the hydrogen ions generated at the cathode electrode 114 react with the oxidized water including ozone generated at the anode electrode 124. In order to provide the advantage of lowering the concentration of the oxidized water to discharge.

On the other hand, in the standby mode in which the first and second pumps P1 and P2 do not operate, a negative pressure (negative pressure) is formed on the side of the chamber in which the cathode electrode 114 of the electrolysis unit 100 is installed to generate a reverse flow. Can be. To prevent this, as shown in FIG. 3, a check valve CV is installed in a flow path between the first pump P1 and the electrolysis unit 100, and a first solenoid valve S1 is disposed at an outlet port 112 side. ) Can be installed. In addition, at the front end of the ozone filter 300 installed behind the electrolysis unit 100, a flow path restricting unit 400, such as a stem mold, is installed so that water passing through the ozone filter 300 flows backwards to generate electricity. It may be prevented from flowing to the decomposition unit 100 side.

That is, when the check valve CV and the first solenoid valve S1 are closed, the pressure of the inner space in which the cathode electrode 114 is installed can be kept constant without any further drop. Therefore, even if the operation of the first and second pumps is stopped, the pressure of the inner space portion in which the anode electrode 124 is installed is not higher, so that the reverse flow of the oxidized water does not occur.

The flow path regulating unit 400 is formed to have a diameter corresponding to or slightly smaller than the diameter of the input side port of the ozone filter 300. The flow path regulating unit 400 serves to reduce the cross-sectional area of the flow path of the input side port of the ozone filter 300 and prevent the pressure drop in the inner space in which the anode electrode 124 is installed. Then, the pressure of the chamber side in which the cathode electrode 114 is installed is increased by the repulsion pressure generated while the oxidizing water passes through the flow path regulating unit 400, and thus the first and second pumps P1 and P2 It is possible to prevent backflow of oxidized water at the time of shutdown. That is, when the first and second pumps P1 and P2 stop, negative pressure may be formed in the internal chamber of the electrolysis unit 100. In this case, the flow path regulating unit 400 may allow the ozone filter 300 The flow path cross-sectional area formed to be spaced apart from the input port of the c) may be increased or decreased depending on the size of the pressure drop in the chamber in which the cathode electrode 114 is formed. As the size of the electrolysis unit 100 increases or decreases, the negative pressure generated in the chamber may also increase or decrease. The cross-sectional area of the flow path restricting unit 400 is set to correspond to the change in the pressure size. Thus, even when negative pressure is generated on the chamber side on which the cathode electrode 114 is disposed, the oxidation water remaining on the flow path formed between the oxidation water discharge port 122 and the ozone filter 300 on the chamber side on which the anode electrode 124 is disposed is negative. Do not flow back to the chamber side where the electrode 114 is formed.

In addition to the stem mold as described above, the flow path restricting unit 400 may be configured as an electrically controllable valve unit, or may be configured as a valve formed so that water flows in only one direction. That is, the flow path regulating unit 400 may be applied to any configuration as long as it can prevent the reverse flow of water.

The embodiments of the present invention described above and illustrated in the drawings should not be construed as limiting the technical idea of the present invention. The protection scope of the present invention is limited only by the matters described in the claims, and those skilled in the art can change and change the technical idea of the present invention in various forms.
