Water Purifier having Function of Electrolysis Disinfection

The present invention relates to a water purifier having an electrosterilization function, and more particularly to a water purifier having an electrosterilization function to remove the chlorine component generated during the electrolysis of water to improve the taste of water.

Recently, as the distrust of tap water due to environmental pollution has increased, the use of water purifiers has been gradually spread. The water purifier is a device for filtering natural water such as tap water or weak water (hereinafter referred to as "raw water"). Filtering the raw water using a filter removes foreign substances or harmful substances contained in the raw water and provides drinking water containing only substances beneficial to the human body.

Hereinafter, with reference to the accompanying drawings will be outlined for the water purification process and configuration of the conventional water purifier.

1 is a schematic view showing the configuration of a filter unit and a water storage tank used in a conventional water purifier. As shown here, a water filter 2 includes a sediment filter for sinking and filtering relatively large particles contained in raw water at the bottom. ), A sun carbon filter (3) for removing chlorine components or odor contained in the raw water passing through the sediment filter (2), and an ionic heavy metal remaining in the raw water passing through the sun carbon filter (3). The filter unit (1) consisting of a membrane filter (4) for removing the, and a carbon filter (5) for removing the chlorine component or odor contained in the drinking water passing through the membrane filter (4) is provided.

That is, the raw water supplied to the water purifier passes through the sediment filter 2 and large particles are primarily filtered, and then the second filtration occurs while passing through the sun carbon filter 3, and the sun carbon filter 3 After passing through the membrane filter (4) is filtered through the third, and finally through the fucarbon filter (5) is purified by completely removing the harmful components to the human body.

As such, the purified water passing through the after carbon filter 5 is stored in the storage tank 6 connected to the after carbon filter 5, and the water stored in the storage tank 6 is one side of the storage tank 6. Extracted to the outside through the extraction unit 7 provided in the user is drinking.

At this time, since the water storage tank 6 is difficult to be completely sealed, bacteria or microorganisms may be proliferated through contact with the atmosphere, which may lead to secondary pollution of purified water. The microorganisms proliferated may be leaked through the purified water, and especially when the water purifier is not used for a long time, the possibility of contamination of the purified water by bacteria and microorganisms becomes higher.

In order to solve this problem, a method of coating silver (Ag) known antimicrobial properties on the activated carbon used in the after-carbon filter (5), a method of supporting a ceramic antimicrobial ball containing a silver component in the water storage tank (6), A method of installing an ultraviolet lamp sterilizer at the rear end of the carbon filter 5 has been proposed.
