Description

Water ionizer having intergrated supply and drain valve

The present invention relates to an ionizer for generating alkaline water and acidic water, and more particularly, a drain pipe for discharging the residual water of the purified water filter and the electrolytic cell, the raw water supply through the water supply pipe can be blocked and the residual water can be discharged at the same time. A water ionizer having an integrated water supply and drain valve.

In general, ionized water refers to alkali reduced water (hereinafter referred to as 'alkali water') and acidic oxidized water (hereinafter referred to as 'acidic water') obtained by electrolyzing water. Alkaline water is similar to the pH of human body fluids, and because the cluster of water molecules (cluster) is small because the body absorption is fast, it has the effect of promoting metabolism and waste discharge. In addition, alkaline water is known to be rich in active hydrogen and to remove free radicals that cause aging and various diseases. On the other hand, acidic water is known to be excellent in sterilization and cleaning power and effective in skin care. As the effects of ionized water are known to the public and various ionized water generating devices (hereinafter, referred to as 'ionized water groups') have been developed, the diffusion rate of ionized water groups is increasing day by day.

1 is a schematic view showing a general configuration of a water ionizer according to the prior art. Conventional ionizers include a water supply pipe 1 to which raw water such as tap water and ground water are supplied, a solenoid valve 3 to open and close the water supply pipe 1, and a water filter 10 to purify raw water to generate purified water. And a purified water pipe (5) through which the generated purified water moves, an electrolyzer (20) for electrolyzing the purified water to generate alkaline water and acidic water, and a controller (30) for controlling the solenoid valve (3) and the electrolyzer (20). It is composed.

A plurality of positive electrode (+) plates and negative electrode (−) plates are provided in the electrolytic cell 20, and a diaphragm for passing only ions having electrical properties is provided between the electrode plates. When a predetermined voltage is applied to the electrode plate, anions such as chloride ions, sulfate ions, and nitrate ions are collected around the anode plate, and oxidation occurs to generate oxygen. In addition, around the negative electrode plate, cations such as calcium ions, magnesium ions and sodium ions are collected, and a reduction reaction occurs to generate hydrogen. As a result, acidic water is produced in the positive electrode plate and alkaline water is produced in the negative electrode plate. The generated ionized water is discharged through the alkaline water discharge pipe 7 and the acidic water discharge pipe 8.

Hereinafter, the problem of the ionizer according to the prior art will be described. In general, water treatment devices, such as water purifiers, cause the scale to get stuck due to foreign matter contained in the water over time. In particular, when the supply of raw water is blocked, the generation of scale is intensified by the water remaining in the purified water filter 10, the purified water pipe 5, and the electrolytic cell 20 (hereinafter, referred to as 'residual water'). The scale generated in the electrolytic cell 20 has a problem of covering the surface of the electrode plate to reduce the electrolytic efficiency, preventing the micropores of the diaphragm from separating ions properly.

In addition, when the scale is accumulated without removing the inside of the ionizer, it may be swept away by water and foreign matters may fall out. This can seriously damage the reliability of the ionizer. Moreover, the residual water stagnated inside the ionizer is easy to multiply various bacteria, and eventually has a problem of drinking contaminated alkaline water.

Meanwhile, in order to solve the above problems, a separate drain pipe may be installed for discharging residual water in the conventional ionizer. In this case, it is conceivable to add a pump for discharging residual water and a solenoid valve for opening and closing the drain pipe.

At this time, the drain pipe opening and closing solenoid valve may be configured to the control unit 30 to be interlocked with the water supply opening and closing solenoid valve (3). However, this method has a disadvantage in that the ionizer becomes complicated because of the addition of a solenoid valve separate from the pump and in terms of cost.

It is obvious that all modifications fall within the scope of the appended claims.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. First, in adding reference numerals to components of each drawing, the same reference numerals are used for the same components as much as possible even if they are shown in different drawings.

[First Example ]

First, with reference to the accompanying drawings looks at the configuration of the ionizer with an integrated water supply and drain valve according to a first embodiment of the present invention.

Figure 2 is a schematic diagram showing the overall configuration of the ionizer according to the present invention.

As shown in FIG. 2, the ionizer 100 according to the first embodiment of the present invention is provided with a water purification filter 200, an electrolyzer 300, and a water supply / exhaust valve 400. These are a water supply pipe 110 and a water purification pipe. 120 is connected via the drain pipe 130. And the control part 500 which controls the water supply and drain valve 400 and the electrolytic cell 300 is provided.

The water supply pipe 110 is connected to a faucet and the like and supplies raw water such as tap water, groundwater, and water stored in a water tank. And, the other end is connected to the water filter 200. An integrated water supply and drain valve 400 is installed at the middle of the water supply pipe 110, whereby the flow path is opened or closed. In this case, the water supply pipe 110 may be divided into a first water supply pipe 110a into which raw water is introduced and a second water supply pipe 110b connected to the water filter 200 based on the integrated water supply and drain valve 400.

The water filter 200 is connected to the water supply pipe 110, and serves to filter the chlorine components, impurities, bacteria and the like contained in the raw water to generate purified water. The water filter 200 is a hollow fiber membrane type filter generally used in an ionizer. The hollow fiber membrane method filters impurities through fine pores formed in activated carbon and passes minerals.

Both ends of the purified water pipe 120 are connected to the lower portion of the purified water filter 200 and the electrolytic cell 300, respectively. When the ionizer 100 is operated, the purified water is moved through the purified water pipe 120, and when the ionizer 100 is not used, the residual water of the purified water filter 200 and the electrolytic cell 300 is moved.

The electrolytic cell 300 serves to generate alkaline water and acidic water by receiving purified water through the purified water pipe 120. A plurality of positive electrode (+) plates and negative electrode (−) plates are provided in the electrolytic cell 300, and a diaphragm is provided between the electrode plates. The electrolyzer 300 includes an alkaline water discharge pipe 140 and an acidic water discharge pipe 150 through which the generated ionized water is discharged, respectively.

One end of the drain pipe 130 is connected to the middle portion of the purified water pipe 120, branched from the purified water pipe 120, and has a structure in which residual water is discharged to the other end. At this time, the other end of the drain pipe 130 is installed to be located at a lower position than one end (where branching from the water pipe 120) of the water pipe 120. And, in the middle of the drain pipe 130, an integrated water supply and drain valve 400 for opening and closing the water supply pipe 110 is installed. The drain pipe 130 may be divided into a first drain pipe 130a branched from the water purification pipe 120 around the water supply and drain valve 400 and a second drain pipe 130b from which residual water is finally discharged.

The water supply and drain valve 400 is an integrated valve of the water supply pipe 110 and the drain pipe 130. The water supply and drain valve 400 is configured to open any one of the water supply pipe 110 and the drain pipe 130 by the control unit 500, and close the other. The water supply and drain valve 400 according to the present embodiment is a solenoid valve composed of a solenoid 410, a cylinder part 420, and a piston 430, as shown in FIGS. 3A and 3B.

The solenoid 410 includes a hollow cylindrical core 414, a coil 412 wound around the core 414, and a plunger 416 built into the core 414 in the case 411. When the voltage is applied to the coil 412, the solenoid 410 causes the plunger 416 to move forward or backward by the solenoid phenomenon. On the other hand, the solenoid 410 is preferably provided with a spring member 418 to be driven only on or off of the applied voltage.

As shown in FIG. 3A, the solenoid 410 has a predetermined voltage applied to the coil 412 so that the spring member 418 is compressed as the plunger 416 is advanced, and the coil 412 is illustrated in FIG. 3B. As the voltage applied thereto is released, the plunger 416 is retracted by the elastic energy of the spring member 418.

The cylinder portion 420 has a cylindrical shape as a whole and is installed below the solenoid 410. The cylinder portion 420 has a cylinder 421 which is a hollow hollow portion is formed therein. In addition, a first inlet hole 422 and a first outlet hole 423 communicating with one side portion of the cylinder 421 in the longitudinal direction, that is, the upper portion of the cylinder 421 are formed. In this case, the first water supply pipe 110a and the second water supply pipe 110b are connected to the first inlet hole 422 and the first outlet hole 423, respectively. The second inflow hole 425 and the second outflow hole 426 communicate with each other in the longitudinal direction of the cylinder 421, that is, the lower portion of the cylinder 421. In this case, the first drain pipe 130a and the second drain pipe 130b are respectively connected to the second inlet hole 425 and the second outlet hole 426.

The piston 430 is installed in the cylinder 421, and is provided with a piston rod 432 integral with the plunger 416. At this time, the piston 431 is formed on the outer surface to be in close contact with the cylinder 421. The piston 430 opens and closes the first inlet and outlet holes 422 and 423 or the second inlet and outlet holes 425 and 426 as the plunger 416 moves forward or backwards.

The controller 500 controls the electrolytic cell 300 and the water supply and drain valve 400. The controller 500 may adjust the pH concentration of the ionized water by adjusting the intensity of the voltage applied to the electrode plate of the electrolytic cell 300. In addition, the controller 500 controls the water supply and drain valve 400 by applying or releasing a predetermined voltage to the solenoid 410 of the water supply and drain valve 400. On the other hand, when the ionizer 100 is operated for a long time, the electrolytic efficiency of the electrolytic cell 300 is lowered due to the plating phenomenon in which calcium, magnesium, and the like are deposited on the negative electrode plate of the electrolytic cell 300. To this end, the control unit 500 may be configured to enable reverse cleaning by periodically applying a voltage of opposite polarity to the electrode plate of the electrolytic cell 300.

Hereinafter, the operation of the ionizer with the integrated water supply and drain valve according to the first embodiment of the present invention having the above-described configuration will be described.

First, the operation state of the ionizer 100 will be described. When the user presses the ionized water generation button exposed on the outer surface of the ionizer 100 to obtain the ionized water supply and drain valve 400 opens the water supply pipe 110 as follows, and shuts off the drain pipe 130.

3A is a cross-sectional view illustrating a raw water supply state of the water supply and drain valve 400. That is, as shown in FIG. 3A, when a predetermined voltage is applied to the coil 412 of the solenoid 410, the plunger 416 compresses the spring member 418 and moves forward. Accordingly, the piston 430 is moved to the lower portion of the cylinder 421. At this time, the piston 430 blocks the second inlet hole 425 and the second outlet hole 426, so that the drain pipes 130a and 130b are blocked. On the other hand, since the first inlet hole 422, the upper portion of the cylinder 421 and the first outlet hole 423 communicate with each other, the water supply pipes 110a and 110b are opened to supply raw water.

Raw water supplied through the water supply pipe 110 flows into the water filter 200 as shown in FIG. 2. The purified water filter 200 filters chlorine and other impurities from raw water and continuously generates purified water. At this time, since the water filter 200 is a filter of the hollow fiber membrane method, the mineral component is not removed.

Thereafter, the purified water generated by the purified water filter 200 is introduced into the electrolytic cell 300 via the purified water pipe 120. The electrolytic cell 300 receives a predetermined voltage by the controller 500 to electrolyze the purified water. Accordingly, alkaline water and acidic water are continuously generated in the electrolytic cell 300, and they are discharged through the alkaline water discharge pipe 140 and the acidic water discharge pipe 150.

Next, a case where the ionizer 100 does not operate will be described. When the user presses the end button of the ionizer 100, the predetermined voltage applied to the electrolytic cell 300 is released and electrolysis is not performed. In addition, the water supply and drain valve 400 blocks the water supply pipe 110 and opens the drain pipe 130 as follows.

3B is a cross-sectional view illustrating a residual water discharge state of the water supply and drain valve 400. That is, as shown in FIG. 3B, when the predetermined voltage applied to the coil 412 of the solenoid 410 is released, the plunger 416 is retracted by the elastic energy stored in the spring member 418.

Accordingly, the piston 430 is moved to the upper portion of the cylinder 421. In this case, the piston 430 blocks the first inlet hole 422 and the first outlet hole 423 to block the water supply pipes 110a and 110b. In addition, since the second inlet hole 425, the lower portion of the cylinder 421, and the second outlet hole 426 communicate with each other, the drain pipes 130a and 130b are opened.

On the other hand, the ionizer 100 according to the present embodiment is completely discharged residual water inside the ionizer 100 for the following reasons. That is, since the end of the drain pipe 130 is located below the branch point of the drain pipe 130, the residual water in the drain pipe 130 is discharged to the outside of the ionizer 100 by gravity. In addition, since both ends of the purified water pipe 120 are connected to the lower portion of the purified water filter 200 and the lower portion of the electrolytic cell 300, all the remaining water in the purified water filter 200 and the electrolytic cell 300 passes through the purified water pipe 120. It can be discharged to the drain pipe (130). As a result, by quickly discharging all residual water inside the ionizer 100 without providing a separate pump, it is possible to prevent the degradation of the electrolytic efficiency due to the generation of scale, and to minimize the contamination of the ionized water due to bacterial growth do.
