Description

An apparatus for producing ozone by electrolysis

The present invention relates to an ozone generator.

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.
