Description

Purification sysytem of a water purifier

The present invention relates to a water purifying system of a water purifier, which is capable of purifying and discharging the supplied water in a purification system for purifying and discharging the feed water.

In more detail,

By changing the arrangement of each filter with different characteristics and functions, the water purification process of water used for cooking and the water used for intake (drinking water) are different, and the discharge position of water in the water purification process is different. The present invention relates to a water purification system that enables the discharge of water at the same time.

Tap water supplied to each consumer through the intake or water supplied from the company is purified after using an appropriate water purification system, and is usually used for filtering for drinking water.

The water purifiers that are widely known and used up to now use a reverse osmosis system using a reverse osmosis filter (RO: REVESE OSMOSIS FILTER) and a hollow fiber membrane system using a hollow fiber membrane filter (ULTRAFIRRATION FILTER).

Reverse osmosis system water purification system has a wastewater that removes minerals that are harmless to the human body in the water purification process, while hollow fiber membrane system water purification system allows minerals to pass while drinking water cannot be purified because of the exposure to heavy metals or other bacteria. There was an inadequate problem for commercialization.

In the conventional water purification method, FIGS. 1A and 1B are schematic diagrams of water purification and power supply showing the water purification system 1 using the reverse osmosis filter.

The sedimentation filter (2) is to be able to supply the raw water, but the main valve 10 is provided to control the supply of raw water, the rear side of the sedimentation filter (2) all carbon filter (3), reverse osmosis filter (4), after-carbon filter (5), ultraviolet sterilization filter (6) is provided in sequence, and the rear side of the ultraviolet sterilization filter (6) is provided with a tank (7) having a water intake valve (12),

The pump 11 is mounted between the all carbon filter 3 and the reverse osmosis filter 4, and the reverse osmosis filter 4 is provided with a sewage line 14 separately. The UV sterilization filter 6 and the tank ( The float switch 13 is attached between 7).

When the power is turned on to operate the water purification system (1),

The main valve 10, the pump 11, the float switch 13, and the ultraviolet sterilization filter 6 are turned on and start to operate, and water purification starts.

The raw water supplied through the main valve 10 passes through the sedimentation filter 2 to remove foreign substances and the like and various organic substances are removed while passing through the low carbon filter 3 and pumped by the pump 11 to reverse osmosis filter. It is supplied to (4), passing through the reverse osmosis filter (4), various bacteria and substances (heavy metals), etc. are removed and separated into the discharge and drinking water, the discharge is discharged to the outside through the discharge line (14) and drinking water is It is supplied to the after-carbon filter 6. Drinking water is passed through the after-carbon filter (5), the components such as various smells are removed, the taste of water is reduced,

The microorganisms are sterilized by the ultraviolet lamp while passing through the ultraviolet sterilization filter 6 and stored in the tank 7 via the flow switch 13. When the drinking water stored in the tank 7 becomes full, the pump 11, the float switch 13, the ultraviolet sterilization filter 6, including the main valve 10, are turned off, and the water purification system 1 operates. Is stopped.

On the other hand, when the intake valve 12 is turned on and the drinking water of the tank 7 is used, the water purification system 1 may not reach the full water level. Thus, the water purification system 1 floats the main valve 10, the pump 11, and the ultraviolet sterilization filter 6. As the switch 13 is turned on, the above-described process is performed to start the purified water again.

The conventional water purification system 1 constructed and operated as described above is pointed out as a disadvantage in the following problem.

It is not suitable in Asian cultures such as Korea because a lot of water is used to cook soup and soup.

In other words, the water purified and stored by the system adopting the reverse osmosis filter 4 is removed even minerals harmless to the human body, and the amount of water taken as drinking water is only 25-30% of the raw water. The rest of the water is discharged through the discharge line 14, so that the consumption of water used as raw water is large, there is a problem that the loss of water is too much when used to cook the purified water in this way.

In addition, since the purified water is stored in the tank 7 after sterilization by the ultraviolet lamp of the ultraviolet sterilization filter 6, the tank 7 is filled in the tank 7 although it is sterilized when supplied to the tank 7. Drinking water is in a state that the chlorine light is removed, so even if a little time passes, the water from which the chlorine light is removed has a problem that bacteria enter and propagate more easily and quickly. There was a need to consume water as quickly as possible.

The present invention is to provide an improved water purification system that can solve the above problems.

The present invention changes the arrangement of the filters having different characteristics and functions, and purifies the water purifier to separate and discharge the water used for drinking water and the water used for cooking according to the discharged position during the water purification process. The purpose is to provide a system.

Another object of the present invention is to discharge the raw water (supply water) supplied to the intake water and cooking water to discharge the water to reduce the amount of sewage when compared with the raw water (supply water) to significantly reduce the loss and waste of water It is to provide a water purification system of purified water purifier.

Another object of the present invention is to obtain a different water according to the purpose by filtering the water used for intake and the process of filtering the water used for intake, which is used for intake The present invention provides a water purifier system for a water purifier that is capable of disinfecting and supplying water in a final discharge process.

The above and other objects and features of the present invention will be more clearly understood by the following detailed description based on the accompanying drawings.

2A and 2B are explanatory diagrams of a schematic diagram and an operation principle showing a specific embodiment of the water purification system according to the present invention.

The inlet side of the sedimentation filter 21 is connected to the raw water supply pipe (30-1) to supply the raw water to be purified, the raw water supply pipe (30-1) is provided with a main valve (30) to control the supply of raw water The water discharged from the discharge side of the precipitation filter 21 was supplied to the all carbon filter 22. In particular, in the all carbon filter 22, the purified water may be supplied to the hollow fiber membrane filter (23: Ultrafirration Filter) and the reverse osmosis filter (24: Revese Osmosis Filter).

The hollow fiber membrane filter 23 is to be introduced by the pressure of the raw water to be supplied, and at the outlet side of the reverse osmosis filter 24 to supply the raw water to be filtered to the after-carbon filter 25,

Water supplied to the after-carbon filter 25 from the hollow fiber membrane filter 23 is to be intermittent by the check valve 33, the reverse osmosis filter 24 to the discharge side to discharge the discharge water (receiving line ( 36).

On the discharge side of the after-carbon filter 25, the cooking object can be discharged by the cooking pipe 35-1 provided with the cooking valve 35, and the water filtered through the flow switch 32 is stored in the tank 26. And the UV sterilization filter 27 is connected to the tank 26 so that the water stored in the tank 26 can be supplied to the UV sterilization filter 27, and the UV sterilization filter On the discharge side of (27), the water intake pipe 34-1 having the water intake valve 34 was discharged through the water intake pipe 34-1 through the UV sterilization filter 27.

Each component provided as described above is to perform the following actions.

The precipitation filter 21 receives raw water to be purified through the raw water supply pipe 30-1, and removes fine dust, debris, and various floats contained in the raw water. It is possible to extend the life of other filters and the like provided on the rear side.

The pre-carbon filter 22 absorbs and removes various organic substances such as chlorine, pesticides, detergents, and carcinogens, such as trahalometal (THM), using activated carbon adsorption.

The hollow fiber membrane filter (23: Ultrafirration Filter) is to purify water through the hollow fiber membrane. Hollow fiber membrane is an inner diameter of 0.1mm and an outer diameter of 0.2mm, the hollow fiber is formed in the inner surface or outer surface with fine pores of 0.01 ~ 0.04㎛,

The bacteria, fungi, microparticles, viruses, and colloidal substances that are larger than these pores can pass, but mineral particles, such as ionic substances and chemicals, cannot pass through.

The reverse osmosis filter (24) is an artificial osmosis membrane method using a reverse osmosis membrane (membrane), and since almost 100 times fine pores are formed than the hollow fiber membrane filter 23, almost all substances contained in water It is an artificial membrane that uses the principle of influx of animal cells and plants to absorb nutrients and discharge waste products by the difference in concentration between the inside and outside of the membrane. In a filter made of such a membrane, the opposite path is used to convert a high concentration of raw water into a low concentration of water.

Pump 31 is a booster pump (Booster Pump) is maintained by the reverse osmosis filter 24 to filter the high concentration (raw water) to a low concentration (water purification) to maintain the pressure so that it can be easily filtered.

Like the carbon filter 22, the carbon filter 25 uses an activated carbon adsorption method to adsorb various organic substances such as chlorine, pesticide components, detergents, and trihalometal (THM), a carcinogen. You will live.

The activated carbon used in the front and rear carbon filters 22 and 23 is charcoal burned at high temperatures around 900 ° C. using wood, coal, coconut shell or sawdust as raw materials, and a myriad of small holes are formed. Since the surface area is 700-1400 m2 per 1 g, the surface area is kept very large, and various organic compounds, chlorine, etc. contained in the water are removed by physical absorption.

The tank 26 stores water (for drinking water) filtered by the rear stage filter 23, which is a previous stage, and is equipped with a float switch 32, which is a level switch. Sensing and controlling the main valve 30 and the pump 31.

The operation relationship will be described below.

The water purification system 20 according to the present invention performs a process of purifying drinking water and a process of purifying water for intake (drinking water).

The process of water purification is carried out as follows.

When the cooking valve 35 is turned on while the main switch (not specifically shown) is turned on, the main valve 30 is turned on to supply raw water through the raw water supply pipe 30-1. The raw water supplied through the raw water supply pipe 30-1 passes through the precipitation filter 21, and various foreign substances including fine dust are removed, and the water passing through the precipitation filter 21 passes through the all carbon filter 22. While chlorine, pesticides, various organic chemicals, etc. are removed, water passing through the carbon filter 22 passes through the hollow fiber membrane filter 23 to remove various bacteria, mold, and colloidal substances. Is passed through without being removed. Water passing through the hollow fiber membrane filter 23 is introduced into the after-carbon filter 25 through the check valve 33, and after passing through the after-carbon filter 25, various organic chemicals such as chlorine are filtered again and then the cooking pipe It is discharged through (35-1).

In this way, when the cooking valve 35 is turned off while the drinking water is purified and discharged, the main valve 30 is also linked to be turned off, so that the discharge of the cooking water is stopped.

On the other hand, when the water for the intake is to be purified, it is possible to operate regardless of the ON / OFF of the intake valve (34).

When power is supplied by operation of a switch (not shown), the main switch 30, the pump 31, and the float switch 32 are kept in the ON state.

When the main switch 30 is turned on, the raw water is supplied to the precipitation filter 21 through the raw water supply pipe 30-1. When the raw water passes through the precipitation filter 21, various foreign substances including fine dust are removed. Water discharged from the precipitation filter 21 passes through the all-carbon filter 22 to remove chlorine, pesticide components and various organic compounds, and the all-carbon filter 22 is forced by the pump 31 which is operated. It is pumped and supplied to the reverse osmosis filter 24.

When passing through the reverse osmosis filter 24 to be purified, it is filtered by the reverse osmosis method, and heavy metal bacteria, viruses, carcinogens, etc. are removed through the pores, which are separated into water and water used as drinking water. The water used for drinking water is supplied to the after-carbon filter 25 and the discharged water is discharged to the outside through the discharge line 36.

When the reverse osmosis filter 24 is supplied to the after carbon filter 25, the hollow fiber membrane filter 23 is closed to the post carbon filter 25 because the state is closed by the check valve 33. Water filtered through 25 is filled in tank 26 by opening of float switch 32.

When the water filled in the tank 26 is full, the float switch 32 detects the full water condition to turn off the main valve 30 and the pump 31.

When the water intake tank 34 is turned on while the water to be used as drinking water in the tank 26 is full, the water in the tank 26 is supplied to the hollow fiber membrane filter 23, but the water is hollow fiber membrane filter 23. When passing through the microorganisms are sterilized by the ultraviolet lamp is discharged through the intake valve 34.

Thus, when the water for drinking water is discharged through the intake valve 34, the water level of the water filled in the tank 26 is lowered, and when the water level is lowered, the main valve 30, the pump 31, and the float switch 32 are When it is turned ON, the above water purification process is performed.

As described above, according to the present invention,

When the drinking water and drinking water are purified, different water purification processes can be used to obtain water with characteristics, and the drinking water can be recovered by using the hollow fiber membrane filter 23 as the main filter. Therefore, it is possible to reduce the waste of water, and to filter only the drinking water by the reverse osmosis filter 24, and to be discharged for use for drinking water by sterilization by the ultraviolet lamp of the ultraviolet sterilization filter 27 to remove the purified water Will be able to improve the product.

In particular, since the water used by the conventional cooking water is filtered by the reverse osmosis filter 24, which has a recovery rate of only about 25% compared to the raw water, 75% of the water is thrown into the water and the loss of water is very high. In addition, since conventionally, the UV sterilized water by the UV sterilization filter 27 is stored in the tank, there is a risk of secondary pollution after water purification and sterilization, and the quality of purified water is deteriorated due to such secondary pollution.

However, the present invention is to obtain the characteristic water according to the use by changing the filling process of water used for cooking or intake and different types of main filter, to prevent the loss of raw water by obtaining the cooking objects separately. Drinking water is to be stored in the tank after the filtered water is stored in the drinking water to be sterilized and discharged when used as drinking water is to prevent secondary pollution and to improve the quality of the purified water.
