Description
본 발명은 역삼투 정수기에 관한 것으로, 더욱 상세하게는 다수의 필터를 하나의 케이스에 내장하여 필터 어셈블리로 형성한 일체식 필터 구성을 갖는 역삼투 정수기에 관한 것이다. The present invention relates to a reverse osmosis water purifier, and more particularly, to a reverse osmosis water purifier having an integrated filter configuration in which a plurality of filters are built into one case and formed as a filter assembly.
역삼투 정수기는 수도수나 지하수를 역삼투 방식에 의해 정수한 다음 사용자에게 제공하도록 하는 장치로서, 통상적인 구조로 된 종래의 역삼투 정수기가 도 1에 도시되어 있다. The reverse osmosis water purifier is a device for purifying tap water or ground water by a reverse osmosis method, and then providing the same to a user. A conventional reverse osmosis water purifier having a conventional structure is shown in FIG.
종래의 역삼투 정수기는 침전필터(4), 승압펌프(5), 선카본필터(6), 역삼투 멤브레인 필터(7) 및 후카본필터(8)가 순차적으로 배치된 구조를 갖추고 있으며, 이들간에 급수배관(3)으로 연결되어 있다. 급수배관(3)은 입구측에 상기 원수배관(1)으로부터 공급되는 원수의 유입을 제어하기 위한 급수밸브(2)가 구비되어 있고, 출구측에 각종 필터들을 통해 정수된 물을 취수용으로 토출하기 위한 취수밸브(9)가 구비되어 있다. The conventional reverse osmosis water purifier has a structure in which the sedimentation filter (4), the boosting pump (5), the sun carbon filter (6), the reverse osmosis membrane filter (7) and the post carbon filter (8) are sequentially arranged. It is connected to the water supply pipe (3). The water supply pipe 3 is provided with a water supply valve 2 for controlling the inflow of raw water supplied from the raw water pipe 1 at the inlet side, and discharges purified water for intake through various filters at the outlet side. A water intake valve 9 is provided for this purpose.
침전필터(4)는 상수도 및 지하수 등의 원수를 수용하여 입자성 물질을 제거하는 기능을 수행하며, 선카본필터(6)는 침전필터(4)를 통과한 정수에서 염소 및 휘발성유기화학물질을 흡착하여 제거하는 기능을 수행한다. 역삼투 멤브레인 필터(7)는 선카본필터(6)를 통과한 정수를 유입하고 이 정수에서 중금속 및 이온성 물질을 제거하는 기능을 수행하며, 후카본필터(8)는 상기 역삼투 멤브레인 필터(7)를 통과한 정수를 수용하여 이 정수 속에 용해되어 있는 가스 형태의 물질을 흡착, 제거하는 기능을 수행하게 된다. 승압펌프(5)는 침전필터(4)와 선카본필터(6) 사이에 위치하여 상기 침전필터(4)를 통과한 정수의 수압을 상승시켜 상기 선카본필터(6) 측으로 운반하는 기능을 수행하고, 역삼투 멤브레인 필터(7)와 후카본필터(8) 사이의 상기 급수배관(3)에는 정수의 역류를 방지하는 역류방지밸브(10)가 구비되어 있다. The sedimentation filter 4 receives raw water such as tap water and groundwater to remove particulate matter, and the pre-carbon filter 6 removes chlorine and volatile organic chemicals from the purified water passing through the sedimentation filter 4. It performs the function of adsorption and removal. The reverse osmosis membrane filter 7 serves to introduce purified water passing through the sun carbon filter 6 and to remove heavy metals and ionic substances from the purified water, and the after carbon filter 8 is a reverse osmosis membrane filter ( It receives the purified water through 7) and performs the function of adsorbing and removing the gaseous substance dissolved in the purified water. The boosting pump 5 is located between the precipitation filter 4 and the sun carbon filter 6 to increase the water pressure of the purified water passing through the precipitation filter 4 to carry the function of transporting it to the sun carbon filter 6 side. In addition, the water supply pipe 3 between the reverse osmosis membrane filter 7 and the post carbon filter 8 is provided with a non-return valve 10 for preventing the reverse flow of purified water.
또한, 상기 역삼투 멤브레인 필터(7)에는 급수배관(3)과는 별도로 농축수배관(11)이 인출되어 있으며, 이 농축수배관(11)을 통해서는 상기 역삼투 멤브레인 필터(7)에서 여과된 중금속 및 이온성 물질이 함유된 농축수를 배출하게 된다. 한편, 상기 농축수배관(11)에는 농축수의 배출을 제어하기 위해 유량제어밸브(12)가 구비된다. In addition, the reverse osmosis membrane filter 7 is withdrawn from the water supply pipe (3) separate from the concentrated water pipe (11), through the concentrated water pipe (11) is filtered through the reverse osmosis membrane filter (7) It will discharge concentrated water containing heavy metals and ionic substances. On the other hand, the concentrated water pipe 11 is provided with a flow control valve 12 to control the discharge of the concentrated water.
이와 같은 구성을 가지는 종래의 역삼투 정수기에서는 원수배관(1)으로부터 급수배관(3)을 통해 유입된 원수가 침전필터(4), 선카본필터(6), 역삼투 멤브레인 필터(7) 및 후카본필터(8)를 순서대로 통과하면서 정수되어 최종적으로 취수밸브(10)를 통해 토출시킬 수 있게 된다. 아울러, 역삼투 멤브레인 필터(7)에서 생성된 농축수는 농축수배관(11)을 통해 외부로 배출시켜 폐기하게 된다. In the conventional reverse osmosis water purifier having such a configuration, the raw water introduced from the raw water pipe (1) through the feedwater pipe (3) is precipitate filter (4), sun carbon filter (6), reverse osmosis membrane filter (7) and after The water is passed through the carbon filter 8 in order to be purified and finally discharged through the water intake valve 10. In addition, the concentrated water generated in the reverse osmosis membrane filter 7 is discharged to the outside through the concentrated water pipe 11 to be disposed of.
그러나, 종래 구조의 역삼투 정수기는 침전필터, 선카본필터, 역삼투 멤브레인 필터 및 후카본필터가 순차적으로 나열되어 있어 정수기의 부피가 커지게 되고, 필터 상호간에 연결하는 급수배관이 서로 복잡하게 구성되어 있으므로 필터의 교환이 용이하지 않은 문제점이 있었다. However, the conventional reverse osmosis water purifier has a sedimentation filter, a sun carbon filter, a reverse osmosis membrane filter, and a post carbon filter, which are sequentially arranged to increase the volume of the water purifier, and the water supply pipes connected between the filters are complicated. There was a problem that the replacement of the filter is not easy.
아울러, 각 필터마다 용적(容積)에 따라 교환주기가 다르므로 각각의 필터들을 별도로 교환하여야 하며, 모든 필터의 교환시기를 완전히 인식한다는 것은 사용자의 측면에서 볼 때 상당히 불편하고 곤란한 문제인 관계로 때때로 필터 교환시기를 놓치게 되는 폐단이 있었다. In addition, since each filter has a different replacement cycle according to the volume, each filter needs to be replaced separately, and it is quite inconvenient and difficult from the user's point of view that the filter needs to be fully recognized. There was a dismissal that missed the exchange.
본 발명은 상기와 같은 문제점을 해결하기 위해 안출된 것으로, 다수의 필터를 하나의 케이스 내에 내장하고 내장된 각 필터의 교환주기를 동일하게 구성하여 일체식 필터 어셈블리로 형성한 일체식 필터 구성을 갖는 역삼투 정수기를 제공하는데 그 목적이 있다.
