The present invention relates to a water purifier using a reverse osmosis water purification and sterilization system, and more particularly, a part of a large amount of concentrated water generated in the water purification process is dissolved solids and polling substances (reverse osmosis filter clogging material) as an ion exchange resin. The present invention relates to a reverse osmosis water purifier that is capable of reducing wastewater generated by recycling of concentrated water and restraining unnecessary waste of water resources by removing water and reintroducing it together with raw water (tap water) to purify and sterilize it.

In general, with the development of the industrial society, natural environment pollution such as water quality and soil pollution is more aggravated, and even though the raw water (tap water) is ingested and purified and distributed, the water purifier has been recently used to purify the tap water in each household and use it as drinking water. It is a widespread trend.

The type of water purifier is a type that purifies and purifies foreign substances or contaminants remaining in the tap water. The reverse osmosis water purification system is adopted and takes the purified water through the sterilization process by UV sterilization lamp. In this regard, a form in which heating is performed by heating means to take water in a state converted into hot water or cold water by cooling by a freezing cycle has been introduced.

On the other hand, a lot of research and development for the dissemination of water purifiers, such as a form that allows consumers to increase the ease of use, or a form that can take a cleaner water is being continued.

The water purification and sterilization system will be briefly described through the embodiment of the water purifier shown in FIG. 1. (To explain the water purification system, water (eg, tap water) supplied to the water purifier will be described as raw water.)

The raw water supplied from the water pipe line is a sedimentation filter (11)-pretreatment carbon filter (12)-membrane filter (13)-corresponding to the reverse osmosis water purification system and sterilization system (10) shown in Figs. Purified and sterilized through the post carbon filter 14-UV sterilization lamp 15, the purified and sterilized water is once stored inside the water tank 30 and the water stored in the water tank 30 is again selected by the user. The water is supplied as cold water or hot water while being guided into the cold water tank 31 having the evaporator 43 of the freezing cycle 40 or the hot water tank 33 having the heater 32. It consists of condenser 42, capillary-evaporator 43, and takes a continuous repetitive cycle of compression-condensation-expansion-evaporation.)

However, in the water purifier of the type which has been widely distributed until recently, a substantial amount of feed water is drained as concentrated water in the water purification process, where the ratio of purified water to raw water is about 1: 4, and the actual purified water is 1 /. 4 and 3/4 were drained as concentrated water.

As a result, a considerable amount of concentrated water (contaminants and organic chemicals have been removed by sedimentation and pretreatment carbon filters) is treated as it is, resulting in increased waste of water resources resulting in uneconomical shortcomings and an increase in water consumption. There was a problem that can not meet the needs of consumers due to the increase in water bills.

Therefore, the present invention has been made to solve the existing problems as described above, the present invention is to remove the dissolved solids and polling material for the concentrated water to be separated wastewater treatment in the water purification process of the raw water using a water purifier to reverse osmosis with raw water The purpose is to provide a competitive water purifier that can be expected to reduce the generation of concentrated water and restrain the waste of water resources by reuse of the concentrated water by re-introducing the purified water into the water purification and sterilization system.

Characteristic technical features of the present invention for achieving this object is, in the form of a water purifier adopting a reverse osmosis water purification and sterilization system to supply raw water, dissolved solids and polling material for the concentrated water that is treated through the membrane filter wastewater treatment It is characterized in that it has a concentrated water guide means that can be re-introduced to the raw water supply side while removing the.

BEST MODE Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

It consists of.

As shown in the figure, the structure of the water purifier is supplied with raw water so that it can be filtered as purified water, and the sedimentation filter 11, the pretreatment carbon filter 12, the membrane filter 13, the post carbon filter 14 and the UV sterilization lamp. Reverse osmosis water purification and sterilization system (10) consisting of (15); A water tank (30) for storing purified water supplied from the system (10); A cold water tank 31 which selectively receives purified water in the water tank and cools it by a conventional freezing cycle 40 to supply cold water; A hot water tank 33 which receives the purified water in the water tank 30 and is heated by the heater 32 to supply hot water; It is a water purifier and consists of other parts for operation.

In such a normal water purifier, the reverse osmosis water purification and sterilization system 10 includes a sedimentation filter 11, a pretreatment carbon filter 12, a membrane filter 13, a post carbon filter 14, and a UV sterilization lamp 15. In the precipitation filter 11, various contaminants (floats) remaining in the incoming raw water are removed and chlorine components and organic chemicals remaining in the raw water are removed while passing through the pretreated carbon filter 12. It is done.

On the other hand, bacteria, viruses, dissolved solids and pollutants present in the raw water are filtered through the membrane filter 13 corresponding to the reverse osmosis system, and a part of the filtered water is transferred to the post carbon filter 14. While being guided, the gas, the pigment, and the odor component are removed to obtain clean water, and the purified water thus obtained is converted into sterilized purified water while passing through the UV sterilization lamp 15 to obtain clean water.

In the membrane filter 13, the concentrated water (containing heavy metals and carcinogens) corresponding to the wastewater is separated and drained.

In the reverse osmosis water purification and sterilization system for the raw water as described above, the present invention is the dissolved solids and polling material between the drain pipe 21 and the raw water inlet pipe 22 to drain the concentrated water generated from the membrane filter 13 The filter member 23 to which the ion exchange resin of a structure that satisfies the condition capable of almost completely eliminating the is applied is connected through the induction pipe 24. This is called the concentrated water guide means (20).

Between the concentrated water drainage pipe 21 and the induction pipe 24 is connected to the valve means 25 having a condition for selectively distributing pressure and flow rate as necessary to connect a portion of the concentrated water to the concentrated water guide means ( The filter member 23 corresponding to 20) is directed to the other side, and the other part of the concentrated water is configured to treat the wastewater.

Referring to the working relationship and effects of the system configuration of the present invention configured as described above are as follows.
