Techniques related to such an electrolytic water generating apparatus can be found in Korean Patent Publication Nos. 2003-0064640, 2002-0020163, and Korean Registered Utility Model Nos. 0250783, 0339730, and the like. As the structure itself is complicated and relatively expensive, it is not popularized.

On the other hand, the cold alkaline water purifier is manufactured in a relatively simple structure by using the above-mentioned principle, the electrolyzed bottled water or raw water obtained along the flow path through the electrolytic cell to separate the acidic water and alkaline water, and the alkaline water in the water supply tank After cooling to a predetermined temperature, it can be used as drinking water.

Regarding such cold alkaline water purifier, for example, as described in Korean Utility Model Registration No. 225289, the cold alkaline water maker which stores the alkaline water obtained by electrolyzing tap water in a cold state and makes it easy to drink whenever needed. Is disclosed.

In addition, the water supply tank 18 has a cooling coil 20 for cooling the alkali water in the water supply tank 18 and a blowout cock for extracting the cold alkaline water in the water supply tank 18 to the outside according to the operation of the compressor 19. (21) is provided.

Therefore, as the tap water supplied through the water supply pipe 13 is supplied to the electrolytic cell 15 while foreign substances and odors are removed while passing through the filters 10, 11 and 12, acidic water and alkaline water by electrolysis This alkaline water is sterilized by the sterilizer 17 and stored in the water supply tank 18 at the same time.

After that, as the compressor 19 is driven, the cooling water 20 through which the coolant flows cools the alkali water in the water supply tank 18 to about 4 ° C to 7 ° C and presses the blower cock 21. Always drink cold alkaline water.

However, in such a cold alkaline water production machine, alkaline water can be obtained from normal tap water, but as the storage time of alkaline water stored in the water supply tank elapses, debris is generated in the water supply tank with a change in pH concentration, which is not suitable for drinking water. There was a problem.

The present invention has been made in view of the above-described conventional problems, and an object of the present invention is to generate alkaline water by electrolysis in a state where the normal temperature water obtained as a water supply tank is first cooled, and the alkaline water is disposed in the water supply tank. As the water is discharged through the re-cooled coil, the temperature and pH of the alkaline water are always maintained in the most suitable state as drinking water, and the structure of the cold-alkaline water purifier that can drink high-quality alkali water by preventing any residue from occurring in the re-cooled coil.

Characterized in that configured to be discharged to the discharge cock through the re-cooling coil.

Here, the electrolyzer may be disposed outside the water supply tank to receive the cooled water through the connection pipe, and the alkaline water generated by the electrolysis may be configured to be discharged to the discharge cock through the connection pipe and the re-cooling coil, or The electrolyzer may be arranged to be connected directly to the recooling coil at the same time as the inside of the feed tank.

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

First, Figures 2a and 2b is a view for explaining the structure of the cold alkaline water purifier according to the present invention, as in the prior art, the segment filter 30 for filtering foreign substances contained in the water and the carbon filter for removing residual chlorine The filter body which consists of the 31 and the activated carbon filter 32 for removing an odor is connected through the water supply pipe 33 and the flow path 34. As shown in FIG.

Of course, the filter body may be installed by adding another filter according to its use or need, and on one side of the filter body, a water supply tank 35 connected to the flow path 34 is disposed to cool the room temperature first. At the same time, it is possible to electrolyze the cooled water into alkaline water and acidic water by being connected to a conventional electrolytic cell 38 via the connection pipe 36 and the calcium filter 37.

In addition, the acidic water separated from the electrolytic cell 38 is discharged to the outside through the check valve 39, the alkaline water is installed in the lower portion of the separation plate 41 inside the water supply tank 35 through the connecting pipe (40) It is comprised so that it may be obtained by the re-cooling coil 42 which has this, and this re-cooling coil 42 is connected by the discharge cock 43 mounted in the bottom face of the water supply tank 35.

Here, the acidic water is supplied to a separate storage tank (not shown) through the check valve 39, when the supply of alkaline water through the discharge cock 43 is stopped, the water flowing into the intake tank 35 At the same time, the air inlet 44 may be opened so that some acidic water may be washed out of the electrolytic cell 38 and the recooling coil 42 and drained to the outside through the discharge cock 43. .

And, in the outer circumference of the water supply tank 35 to cool the room temperature water stored in the water supply tank 35 to the most suitable temperature as drinking water of about 4 ℃ to 7 ℃ according to the operation of the compressor 45 as in the prior art. A cooling coil 46 is mounted, and normal air outlets 47 and drains 48 are provided above and below the water supply tank 35.

According to the present invention configured as described above, when the cup or bottle is brought into contact with the discharge cock 43 to drink alkaline water, the water stored in the water supply tank 35 and maintained in the primary cooling state is connected to the connection pipe 36. And into the electrolytic cell 38 together with the dissolved calcium through the calcium filter 37.

In the electrolytic cell 38, as power is applied to the diaphragm provided between the positive electrode plate and the negative electrode plate, positive ions of mineral components such as calcium and magnesium present in water adhere to the negative electrode plate, and chlorine, sulfuric acid, sulfur, etc. Negative ions of will stick to the anode plate.

At the same time, the anode hydroxyl ions (OH ^-) at the cathode-side receiving a proton (H ⁺⁾ of the so discard is in molecular oxygen (O₂) to fly through the air by increasing the hydroxyl ion water is acidified, in the negative electrode side of the anode When it is received, it becomes a hydrogen molecule (2H) and blows it into the air, but since the amount of hydrogen molecules increases, active hydrogen ions increase, water becomes alkaline.

Accordingly, the water entering the electrolytic cell 38 is electrolyzed into acidic water and alkaline water, and the acidic water is discharged to the outside through the check valve 39, and the alkaline water is supplied to the water supply tank 35 along the connection pipe 40. The water is discharged to the discharge cock 43 via the re-cooling coil 42 installed in the interior of the pipe.

At this time, the alkaline water is maintained by the cooling coil 46 operated by the compressor 45 in the water supply tank 35 to maintain a temperature of about 4 ° C. to 7 ° C., which is most suitable as drinking water, and then the water has a calcium filter 37. And while the temperature rises slightly in the process of passing through the electrolytic cell 38, the alkaline water electrolyzed in the electrolytic cell 38 is immediately introduced into the re-cooling coil 42 inside the water supply tank 35 along the connection pipe 40 Since it is cooled again, it is possible to drink high-quality alkali water through the discharge cock 43.

In addition, the acidic water is supplied to the storage tank (not shown) through the check valve 39 can be used for purposes other than drinking water, and when the supply of the alkaline water is stopped, the water supplied by the circuit operation is blocked.

The electrolytic cell can be transferred to the interior of the electrolytic cell 38A, and the electrolytic cell 38A, the recooling coil 42A, and the discharge cock 43A are directly connected to each other.

Therefore, the water supplied to the inside of the water supply tank 35A through the flow path 34A and the calcium filter 37A, as in the above-described embodiment, enters the electrolytic cell 38A through the connection pipe 40A after the first cooling. The alkaline water generated by electrolysis in the electrolytic cell 38A can be immediately discharged through the recooling coil 42A and the discharge cock 43A.

The embodiments described above are described for the most preferred example of the present invention, and are not limited to the above embodiments, and it will be apparent to those skilled in the art that various modifications can be made without departing from the technical spirit of the present invention.
