Description

An apparatus for producing ozone by electrolysis for Beverage supply device

The present invention relates to an ozone generating device for a beverage supply device.

Due to increasing water pollution and increased interest in healthy living, recently, drinking water is not used as drinking water, drinking bottled water or drinking water, or purifying tap water using a water purifier to use it as drinking water.

Such a water purifier has a filter unit that normally separates various contaminants and harmful components from a water source at an initial stage of operation. Since contamination by bacteria or the like may occur in the storage tank, in order to protect the water purifier from such bacterial contamination, it is necessary to sterilize the flow path and the storage tank after a certain period of time.

Conventionally, in order to clean or sterilize the water storage tank, after the operation of the water purifier is stopped, the water storage tank has to be separated from the water purifier, and the water storage tank separated from the water purifier is manually cleaned or The need to sterilize is cumbersome. Because of this hassle, it is difficult for the user to perform the timely cleaning or sterilization of the storage tank in which contaminants have accumulated, and there is a problem that the storage tank is not maintained in a clean state at all times.

In order to improve such a hassle, in recent years, research on a technology capable of self-cleaning the storage tank of the water purifier without separating the storage tank has been conducted. However, in order to self-clean the water purifier in this way, the water purifier must have a device capable of generating the sterilization water itself to sterilize the flow path inside the water purifier, which is generated during the electrolysis of water. It uses a lot of ozone water formed by including ozone in water.

The ozone water generating device through electrolysis of water has been described in principle in Republic of Korea Patent No. 10-0564654. The ozone water generating device includes a frame that is stacked and bonded to each other, a positive electrode and a negative electrode installed inside the frame, and a solid polymer electrolyte membrane for transferring hydrogen ions generated by an electrolysis reaction between the anode and the cathode electrode. Thus, high concentration of ozone water can be produced.

However, according to such a configuration, it is not easy to install inside the water purifier, which is a recent miniaturization trend, and because there is a limited amount of ozone water that can be produced at one time, there is also a problem that can not be applied in industrial facilities that require sterilization water on a large scale.

Hereinafter, the operation of the electrolytic ozone generating apparatus according to the present invention will be described with reference to the cross-sectional view of FIG.

When purified water or raw water flows into the first pipe 21, the introduced raw water flows into the water injection pipe 40. At this time, since the end of the water injection pipe 40 is blocked by the fixing protrusion 13 of the first housing 10, the nozzle 45 is the only passage through which the introduced water can exit.

At this time, a plurality of nozzles 45 are formed to penetrate only in the direction toward the electrolytic unit 30, as shown, in this case, the nozzle 45 is evenly distributed in an area corresponding to the exposed surface of the electrolytic unit 30. It may be distributed. That is, the number of rows and columns of the nozzles 45 may be determined according to the area of the electrolytic unit 30.

In addition, the diameter of the nozzle 45 may be formed to be the same, or may be formed to have a different diameter. For example, the diameter of the nozzle 45 in the portion facing the portion where the scale is largely generated on the surface of the electrolytic unit 30 is formed large, so that a larger hydraulic pressure and a large amount of water are introduced, the scale is electrolyzed. It is desirable to be able to separate it from the unit 30.

Therefore, water introduced through the first pipe 21 may be uniformly sprayed into the electrolytic unit 30 through the nozzle 45. The configuration of acquiring ozone water through water injection is a prior art mentioned in the background art, which is described in detail in Korean Patent No. 10-0564654 and the like, and thus, redundant description is omitted. The present invention is the ozone water generating apparatus as described above, the scale generation problem that may occur when the water supplied to the electrolytic unit 30 is concentrated in the vicinity of the center and the entire surface of the electrolytic unit 30 It can improve the disadvantage that can not be used for decomposition.

In addition, the water in the space portion of the first and second housings 10 and 20 in which the cathode is disposed maintains only a constant level at which electrolysis is possible, and the water is continuously provided to the portion in which the anode is disposed through the water injection pipe 40. While spraying, it is possible to generate a larger amount of ozone water than the conventional and discharge to the second pipe 22 side through the flow path (35).

In addition, as described above, not only ozone water is discharged to the second pipe 22 side, but also hydrogen gas generated during the electrolysis process in the electrolytic unit 30 is discharged together, so that a separate gas outlet does not need to be configured. A more compact ozone water generator can be configured.

On the other hand, in the above embodiment, the configuration of the first and second housings 10, 20 to be detachably installed in one embodiment has been described as an embodiment, but not limited to this, depending on the design, the electrolytic unit It is also possible to comprise the left and right separated about the 30.
