Description

Water treatment equipment with sterilization function {WATER TREATMENT APPARATUS FOR FUNCTIONING AS A STERILIZER}

The present invention relates to a water treatment device having a sterilization function, and in particular, an electrolysis unit is provided inside the tank unit, and electrolytically decomposes drinking water inside the tank unit through the electrolysis unit to generate sterilization water, and circulate the sterilization water. The present invention relates to a water treatment device having a sterilization function for cleaning a tank part.

In recent years, various types of water purifiers have been widely used in homes as living standards have improved and the importance of drinking water has increased. In general, a water purifier uses a pretreatment filter, an activated carbon filter, an ultrafiltration membrane filter, a reverse osmosis membrane filter, or the like.

According to such a general water purifier, water passing through an activated carbon filter completely removes residual chlorine in tap water, and uses raw water such as tap water to purify the drinking water.

However, these conventional water purifiers have been shown to cause various problems. First, there is a problem in that the purified water can be dissipated and the microorganisms proliferated in the activated carbon filter can be discharged, and the microorganisms introduced from the outside air can proliferate in the tank.

In addition, the water purifier is equipped with a water tank to maintain the flow rate or to store the purified water for the cold-temperature function, and the user is at least one week to suppress the growth of microorganisms because the microorganisms grow while the purified water is stored in the tank. There is an uncomfortable problem of cleaning and sterilizing at least once.

Meanwhile, to solve this problem, existing water purifier manufacturers use a water tank as an antimicrobial material, attach a UV sterilizer to the water tank, automatically drain the stored water after a certain period of time, or automatically circulate the water tank, In order to minimize contact with outside air, a method of sealing or dissolving a small amount of chlorine in an electrode sterilizer is used.

However, even with these methods, the inflow of microorganisms grown on activated carbon and the residual microorganisms in the air are not completely suppressed. That is, the tank using the antimicrobial agent is effective in suppressing the growth of microorganisms generated on the wall of the tank, but there is a problem in that the growth of the microorganisms propagated in the water by proliferation in the activated carbon filter cannot be suppressed.

In addition, when the UV sterilizer is attached, there is a problem in that the microorganism cannot be completely sterilized in water because there is no sterilization residual of the UV light and the entire tank is not sterilized.

In addition, sterilization by dissolving silver from silver activated carbon may not be a fundamental solution because silver remains in drinking water and may be harmful to health, and it is necessary to continuously dissolve trace amounts of chlorine in water by generating chlorine by electrolysis. Chlorine removal has the disadvantage of dissolving chlorine in the water purifier, which is an important function, so that it cannot function as a water purifier.

In addition, the conventional water purifier must sterilize the inside of the UV sterilization filter because microorganisms grow in the part of the rear end of the UV sterilization filter where the UV wavelength is not affected. shall.

On the other hand, free residual chlorine is widely used as a disinfectant disinfectant in tap water, and the water supply standards stipulate that residual chlorine of 0.4 mg / L or more remains in the tap water. To prevent microorganisms from occurring.

However, in the water purifier, there is no sterilization residue as 100% of free chlorine is removed in activated carbon filter process, and microorganisms flow from the air and activated carbon filter and multiply on the wall of the tank during water storage process. It may exceed the reference 100 CFU / mL.

In reservoirs, microorganisms multiply mainly on the wall and can form thousands of colonies per millimeter (mL) with microorganisms from outside. Therefore, it is necessary to regularly sterilize the wall of the tank with a disinfectant disinfectant and to minimize the inflow of microorganisms from the outside, but it is difficult for the actual users to clean the tank regularly because of the structure of the water purifier tank. In addition, since the microorganism is continuously proliferated in the activated carbon filter, there is a problem in that the microorganism cannot be suppressed only by cleaning the tank.

Therefore, the present invention has been made in order to solve the above problems, having an electrolysis unit in the tank, electrolyzing the drinking water inside the tank through the electrolysis unit to generate sterilization water, circulating sterilization water It is an object of the present invention to provide a water treatment device having a sterilization function capable of cleaning the tank part.
