The present invention relates to a cold ionizer, and more particularly, to a cold ionizer for providing cold ionized water ionized in an electrolytic cell.

In general, an ionizer is a device that provides alkaline or acidic water when a user's request is obtained by separating purified water or raw water from an electrolytic cell into acidic and alkaline water through a filter unit, and may be used with a cooling or heating function.

1 is a schematic configuration diagram showing an example of a conventional ionizer.

As shown in FIG. 1, the conventional ionizer 40 includes a plurality of filters 11, 12, 13, and 14, and a filter unit 10 for filtering and purifying tap water, and the filter unit 10. An electrolytic cell 20 for generating acidic water and alkaline water by electrically decomposing purified water from the purified water, a storage tank 30 for storing alkaline water generated in the electrolytic cell 20, and stored in the storage tank 30. A takeout cock 32 for taking in alkaline water is provided.

As shown in FIG. 1, the filter unit 10 may include, for example, a precipitation filter 11 that filters particles of purified water from the raw water supply unit 16, and removes chlorine components and odors from the purified water. To remove the odor contained in the precarbon filter 12, the membrane filter 13 for removing the fine particles remaining in the raw water passed through the precarbon filter 12, and the water passed through the membrane filter 13 It may be configured as a post carbon filter 14, and may further include a pressurizing pump 15 for moving the supplied raw water to a predetermined pressure.

In addition, the storage tank 30 may include a tank for storing cold water and / or hot water as well as a normal temperature tank for storing normal temperature water, as well as a separate cooling and / or heating function.

As such, the purified water filtered by the filter unit 10 is ionized through the electrolytic cell 20, wherein the acidic water is stored in the acidic water storage tank (not shown) through the acidic water discharge pipe 22 to meet the user's request. Used or discharged to the outside.

In addition, the alkaline water is stored in the storage tank 30 through the connecting pipe 21 is provided to the user through the discharge pipe 31 and the discharge coke 32 when the user's request.

The ionizer 40 described above is configured in the order of the filter unit 10 → the electrolytic bath 20 → the storage tank (cold water tank) 30 in view of the ionized water treatment step. Therefore, the alkaline water generated through the electrolytic cell 20 is stored in the storage tank (cold water tank) 30 until the user withdraws.

Thus, the constant ionizer 40 has the advantage of being effective in maintaining the temperature of cold ionized water.

However, when the alkaline water stays in the storage tank 30 for a long time, the pH concentration gradually decreases as the ionic component of the alkaline water disappears over time. Furthermore, when stored in the storage tank 30 made of a metal material, there is a problem that the ionic component quickly disappears because the ionic component is combined with the metal to return to the stabilized state.

In addition, the alkaline water has a problem that scale is formed in the storage tank 30 because the calcium component of the ionized water is entangled with crystals over time.

In addition, since the alkaline water stored in the storage tank 30 is extracted, there is a problem that an immediate pH change is not made.

Accordingly, the ionized water treatment step is arranged in the order of filter part → storage tank (cold water tank) → electrolytic bath, and the purified water is stored at low temperature through the filter part, and when the user's request is made, the cold water tank ionizes the purified water in the cold water tank. Was developed.

Consists of.

Therefore, the ionizer 70 is operated only when the user's request, the pump 55 is operated to supply the purified water cooled from the cold water tank 50 to the electrolytic cell 60 by the discharge pipe 61 and the discharge coke 63 Since the supply of cold alkaline water through not only can provide the alkaline water without the loss of ionic components, the scale is not formed in the cold water tank (50).

However, the above-described ionizer 70 must be provided with a power unit such as a pump 55 for forming a negative pressure in the electrolytic cell 60, so the movement distance of the cold water is not only extended, but the cold water is operated by the operation of the pump 55. There is a problem that it is difficult to supply a uniform temperature of cold water to increase the temperature.

In addition, various parts 55 and 60 exist after the cold water tank 50, and particularly, water remains inside the pump 55 and the electrolytic cell 55, and thus the temperature of the cold ionized water is increased during initial intake. .

In addition, noise is generated by the operation of the pump 55, and various problems necessary for the pump 55 and its connection are consumed, and a problem of cost increase occurs.

Accordingly, there is a need for a cold ionizer to solve the problems with the ionizer of FIGS. 1 and 2 to provide cold ionized water having a uniform pH concentration and a constant temperature.

The present invention is to solve the above problems, it is an object of the present invention to provide a cold ion water group with a uniform pH concentration and less scale formation in the storage tank.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

3 is a schematic view showing the structure of a cold ion water heater according to the present invention.

As shown in FIG. 3, the cold ion water heater 100 according to the present invention includes a storage tank part 200, an electrolytic cell 400, a cold water feed valve 310, and a discharge part 500. In addition, the filter unit 110 may include.

The filter unit 110 is provided with at least one filter for supplying the raw water introduced (filtered) to the storage tank unit 200, the filter unit 110 may use any filter combination.

As an example, the filter unit 110, as shown in Figure 3, pre-filter (sediment filter, sediment filter) for filtering the particles of the particles in the raw water supplied from the raw water supply unit 116, in the raw water A pre-carbon filter 112 for removing chlorine or odor, a membrane filter 113 for removing fine particles remaining in raw water passing through the precarbon filter 112, and the membrane filter ( And a post-carbon filter 114 for removing odors and pigments contained in the water passed through 113, adding a high-purity filter to filter the residue of relatively large particles in purified water. It can be provided as.

In this case, the living water that does not pass through the membrane filter 113 may be configured to be discharged through the living water discharge unit 117.

The filter unit 110 may vary the type of filter according to the performance of the required water purifier, may add or subtract the number of filters, pressurize the raw water supplied to a predetermined pressure to move to the membrane filter 113. It may further include a pressurizing pump 115 to.

The storage tank unit 200 stores about 5 to 20 liters of water supplied through the raw water supply unit 116 or the filter unit 110 and discharges the water, and the water level is reduced below a predetermined height by the water level sensor 240. When the water is supplied again through the raw water supply unit 116 or the filter unit 110.

The storage tank unit 200 is a room temperature tank 210 for storing the water supplied from the raw water supply unit 116 or the filter unit 110 at room temperature, a cold water tank 220 to generate cold water, and to generate hot water It may include a hot water tank 230, the type, location and capacity of the tank (210, 220, 230) provided in the storage tank unit 200 can be changed according to the design specifications.

For example, the storage tank 200 is a room temperature tank 210 for storing the water directly introduced from the outside or filtered by the filter unit 110, and a separator (not shown) in the lower portion of the room temperature tank 210 It may be configured to have a cold water tank 220 is arranged to be divided by, it may be provided with only the cold water tank 220.

The electrolyzer 400 receives water stored in the cold water tank 220 to generate ionized water of acidic and alkaline water through an electrolysis reaction between the anode electrode and the cathode electrode provided therein.

In addition, the electrolytic cell 400 is preferably disposed below the storage tank part 200 so that water is supplied into the electrolytic cell 400 by the water pressure of the water stored in the cold water tank 220.

The downstream side of the electrolytic cell 400 is provided with an alkaline water extraction unit 511 for discharging the alkaline water and an acidic water drain portion 521 for discharging the acidic water, and discharges the ionized water generated when the ionized water is generated.

At this time, the acidic water drain portion 521 may be provided with a separate acidic water storage tank (not shown) and acidic water intake coke (not shown) to use the acidic water, but water remains in the electrolytic cell 400. It is desirable to remain open so as not to. To this end, the acidic part drain part 521 may be disposed under the electrolytic cell 400 so that water remaining therein is discharged by gravity.

That is, since the ionized water generated in the electrolytic cell 400 is discharged to the outside through the acidic water drain 521 and the alkaline water extracting part 511, the internal water of the electrolytic cell 400 does not remain, and thus initial intake When only the water supplied from the cold water tank 220 is ionized, the temperature of the first cup of cold water may not be increased.

The cold water feed valve 310 is provided between the cold water tank 220 and the electrolytic cell 400 is configured to be a direct-acting type valve for turning on / off the water in the tank.

When the user takes in the ionized water, the cold water feed valve 310 is opened by the operation of a controller (not shown) or by a mechanical mechanism by the alkaline water intake cock 513 to store the water stored in the cold water tank 220 in the cold water tank. The water is supplied to the electrolytic cell 400 by the water pressure of 220, and when the ionized water is not collected, the water is closed to prevent the water from being supplied to the electrolytic cell 400.

At this time, the cold water feed valve 310 is preferably directly connected to the cold water tank (220). That is, the cold water feed valve 310 is preferably directly connected between the cold water tank 220 and the electrolytic cell 400 without a separate connection in order to minimize the head head loss between the cold water tank 220 and the electrolytic cell 400. Do.

As such, since a separate power unit such as a pump is not required by using the cold water feed valve 310, water is collected by the operation of the power unit and water remaining therein, unlike a conventional cold ion water heater using a pump. It is possible to obtain an advantage that the temperature of the cold ionized water does not rise.

In addition, since there is no separate power unit, it is possible to obtain an advantage of preventing noise and cost increase by the power unit.

On the other hand, when the room tank 210 for storing the water introduced into the storage tank 200 at room temperature is provided may be configured to directly intake water at room temperature through a separate intake line (not shown) However, as shown in FIG. 3, a room temperature water feed valve 320 connecting the electrolytic cell 400 and the room temperature tank 210 may be provided.

The cold water feed valve 320 may be configured to supply the water stored in the normal temperature tank 210 to the electrolytic cell 400 by the water pressure of the normal temperature tank 210, similar to the cold water feed valve 310 described above.

At this time, the room temperature water feed valve 320 is preferably configured to be connected to the room temperature tank 210 and the electrolytic cell 400 in the shortest distance to minimize the head head loss. That is, the head loss can be prevented by minimizing the length of the supply line 211. In addition, like the cold water feed valve 310 may be configured to be connected directly without a separate connection pipe.

At this time, the amount of water supplied to the electrolytic cell 400 can be changed by adjusting the inlet and outlet inner diameter of the feed valve 310 and the flow path area and stroke therein.

In particular, the feed valves 310 and 320 preferably have the same cross-sectional area of the inlet and outlet of the feed valves 310 and 320 and the cross-sectional area of the internal flow path to ensure a sufficient flow rate.

On the other hand, when the hot water tank 230 for generating hot water in the storage tank 200 is configured to take hot water through the discharge pipe 531, the valve 532 and hot water coke 533 as shown in FIG. It may be, but may be configured to pass through the electrolytic bath 400 as described above to obtain warm ionized water.

As such, when a part or the whole of the room temperature tank 210, the cold water tank 220, or the hot water tank 230 is provided, the flow path may be formed so as to diversify the extraction line and take the water according to the user's choice. In this case, the controller (not shown) enables the intake of various types of water, such as cold ionized water, room temperature ionized water, warm ionized water, room temperature water, cold water, and hot water.

The discharge part 500 includes an acidic water drain part 521 for discharging acidic water generated in the electrolytic cell 400 to the outside, and an alkaline water extraction part 511 for discharging alkaline water to the outside.

On the other hand, it is necessary to reverse cleaning for cleaning the electrode to remove the scale formed on the electrode of the electrolytic cell 400 to improve the life of the electrode.

To this end, the discharge unit 500 may include a flow path switching valve 510 for selectively discharging the ionized water supplied from the alkaline water extraction unit 511 to the alkaline water extraction coke 513 or the acidic water drain 521. have.

That is, when reverse washing is performed, the electrolyzer 400 generates ionized water (cleaning water) having a changed polarity, and thus, the alkaline water extracting unit 511 has a flow path switching valve 510 to discharge the washing water. do.

In the case of reverse washing, the flow path switching valve 510 discharges the washing water discharged through the alkaline water extracting unit 511 to the outside through the acidic water draining unit 521 connected to the discharge pipe 512. The flow path is switched to the alkaline water intake coke 513 so that alkaline water at an appropriate pH concentration is supplied.

The operation of the flow path switching valve 510 is performed by a controller (not shown). For example, the flow path switching valve 510 may be reverse-washed in response to a predetermined time or an ionized water extraction frequency.

As described above, by performing reverse cleaning with the flow path switching valve 510, not only the electrode life of the electrolytic cell 400 can be improved, but also ionized water having a uniform pH concentration can be obtained.

On the other hand, the cold ion water heater 100 according to the present invention is provided with a known control unit (not shown) as described above to control the opening and closing of the various valves (310, 320, 510) and reverse cleaning of the electrolytic cell 400, and various types of water It can be configured to be controlled to be withdrawable.

The operation of the present invention having the above configuration will be described with reference to FIG. 3.

As shown in FIG. 3, the water supplied through the raw water supply unit 116 is filtered through the filter unit 110 and stored in the storage tank unit 200 or directly to the storage tank unit 200 through the raw water supply unit 116. Stored.

At this time, the cold water stored in the cold water tank 220 provided in the storage tank unit 200 is supplied to the electrolytic cell 400 by the opening of the cold water feed valve 310 and the water pressure of the cold water tank 220, the electrolytic cell 400 The ionized alkaline water can be taken in through the flow path switching valve 510 and the alkaline water extraction coke 513, and the acidic water is discharged to the outside through the acidic water drain 521 so that the water inside the electrolytic cell 400 is discharged. It does not remain.

Similarly, the room temperature water stored in the room temperature tank 210 is supplied to the electrolytic cell 400 by the water pressure of the room temperature tank 210 of the room temperature water feed valve 320 and ionized.

Such, whether the tank (210, 220, 230) provided and the position can be changed according to the design specifications, it can be configured to directly withdraw without going through the electrolytic cell (400).

For example, hot water stored in the hot water tank 230 may be configured to provide warm ion water through the electrolytic cell, but may be withdrawn without passing through the electrolytic cell as shown in FIG.

As such, even when the feed valves 310 and 320 are used, a sufficient amount of water may be supplied to the electrolytic cell 400 by the water pressure in the tanks 210, 220 and 230.

As a result, it was possible to take a sufficient amount of water with 2.1LPM (liter / minute) for water level of 200mm cold water tank and 1.8LPM at the lowest water level (refining water height) with water level of cold water tank 160mm. The water withdrawal performance similar to that of the conventional conventional cold water heater could be realized.

In this way, the amount of water supplied to the electrolytic cell 400 can be changed by adjusting the inlet and outlet inner diameter of the feed valve 310 and the flow path area and stroke therein.

On the other hand, when the reverse cleaning of the electrolytic cell 400, the washing water discharged through the alkaline water extraction unit 511 in the electrolytic cell 400 is discharged to the discharge pipe 512 by switching the flow path of the flow path switching valve 510 Through the acidic water drain portion 521 is discharged.

Such reverse cleaning may be performed every time by the operation of the control unit or every time a constant number of times water collection is made.

According to the present invention as described above, by installing the electrolytic cell after the storage tank portion, it is possible to obtain a cold ion water group with a uniform pH concentration and less scale formation in the storage tank.

In addition, according to the present invention, since a separate power unit such as a pump is not provided, noise is reduced, manufacturing cost is reduced, and the temperature of cold ionized water is not lowered.

In addition, since there is no water remaining in the electrolytic cell, in particular, there is no fear of water remaining in the pump because there is no pump, cold ionized water having the same temperature as the cold water temperature in the cold water tank can be provided even when the alkaline water is initially taken out.

In addition, it is possible to obtain an effect of performing reverse washing to suppress the formation of scale in the electrolytic cell and to improve the life of the electrode.

While the invention has been shown and described with respect to particular embodiments, it will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention as set forth in the claims below. I want to make it clear.
