Description
본 고안은 정수기의 필터에 관한 것으로서, 더욱 상세하게는 케이스로 부터 필터의 교환을 가능하게 하므로써 원가를 절감하고, 폐기물량을 줄이게 되는 필터교환용 필터 케이스구조에 관한 것이다.The present invention relates to a filter for a water purifier, and more particularly, to a filter case structure for filter replacement that reduces the cost and reduces the amount of waste by enabling the exchange of the filter from the case.
환경 오염으로 인하여 수도물에 대한 불신이 높아지면서 정수기의 사용이 점차 확산되고 있는 실정이다.The use of water purifiers is gradually spreading due to the increase of distrust in tap water due to environmental pollution.
정수기는 수도물이나 또는 약수와 같은 자연수(이하 원수라함)를 여과하기 위한 장치로서, 원수를 다양한 종류의 필터링 수단을 통과시킴으로써, 원수에 포함된 이물질이나 유해 물질을 제거하고 인체에 유익한 물질만이 포함되는 음용수를 제공한다.A water purifier is a device for filtering natural water such as tap water or weak water (hereinafter referred to as raw water). The water is passed through various kinds of filtering means to remove foreign substances or harmful substances contained in raw water and include only substances that are beneficial to the human body. To provide drinking water.
상기와 같은 정수기는 다양한 종류의 것이 사용되고 있으며, 역삼투압 방식의 정수기가 그 대표적인 것이라 할 수 있다.Various kinds of water purifiers as described above are used, and the reverse osmosis type water purifier may be referred to as a representative one.
역삼투압 정수기는 소위 역삼투압 필터(이하 맴브레인 필터라 함)를 사용하여 원수를 정화시키는 것으로서, 상기 맴브레인 필터는 직경이 매우 작은 다수의 기공으로 형성되어서 이물질이나 유해 물질을 제거하게 된다.The reverse osmosis water purifier purifies raw water by using a so-called reverse osmosis filter (hereinafter referred to as a membrane filter). The membrane filter is formed of a plurality of pores having a very small diameter to remove foreign substances or harmful substances.
도 1에는 일반적인 역삼투압 정수기의 일구성예가 도시되어 있다.Figure 1 shows an example of the configuration of a general reverse osmosis water purifier.
도시된 바와 같이, 역삼투압 정수기는 수도물이나 자연수와 같은 원수의 공급을 제어하기 위한 원수 밸브(1)와, 상기 원수 밸브(1)를 통과한 원수중의 비교적 큰 입자의 찌꺼기를 여과하기 위한 고탁도 필터(2)와, 상기 고탁도 필터(2)를 통과하면서 여과되지 않은 비교적 작은 입자의 찌꺼기를 여과하기 위한 침전 필터(3)와, 공급되는 원수를 소정의 압력으로 이동시키기 위한 가압용 펌프(4)와, 원수중의 염소 성분이나 냄새를 제거하기 위한 전카본 필터(5)와, 상기 전카본 필터(5)를 통과한 원수중에 잔류하는 이온성 중금속을 제거하기 위한 맴브레인 필터(6)와, 상기 맴브레인 필터(6)를 통과하는 원수의 식수대 폐수 분리 비율을 조정하며 폐수를 방류하는 폐수 조절기(7)와, 상기 맴브레인 필터(6)를 통과한 식수중에 포함된 염소 성분이나 냄새를 제거하기 위한 후카본 필터(8)와, 상기 후카본 필터(8)를 통과한 원수중의 세균을 제거하기 위한 살균 필터(9)와, 정수를 저장하기 위한 것으로서, 정수를 방출하는 밸브가 연결된 정수 탱크(10)로 구성되어 있다.As shown, the reverse osmosis water purifier has a raw water valve 1 for controlling the supply of raw water, such as tap water and natural water, and a high filter for filtering the residue of relatively large particles in the raw water passing through the raw water valve 1. Turbidity filter (2), precipitation filter (3) for filtering the residue of relatively small particles not filtered while passing through the high turbidity filter (2), and a pressurizing pump for moving the supplied raw water to a predetermined pressure (4), an all-carbon filter (5) for removing chlorine components and odors in raw water, and a membrane filter (6) for removing ionic heavy metals remaining in raw water passing through the all-carbon filter (5). And a wastewater regulator 7 for adjusting the drinking water to wastewater separation ratio of the raw water passing through the membrane filter 6 and discharging the wastewater, and removing chlorine components or odors contained in the drinking water passing through the membrane filter 6. doing Water purification tank connected to the fucarbon filter (8), the sterilization filter (9) for removing the bacteria in the raw water passing through the fucarbon filter (8), and the valve for discharging the purified water It consists of (10).
상기 고탁도 필터(2)는 얇은 철망과 같은 것이 사용되며, 커다란 찌꺼기를 여과하는데 이용된다. 또한 침전 필터(3)는 부직포로 구성되며, 모래나 진흙과 같은 비교적 작은 입자의 이물질을 여과하는 것이다.The high turbidity filter 2 is used as a thin wire mesh, and is used to filter large debris. In addition, the precipitation filter 3 is composed of a nonwoven fabric, which filters foreign matter of relatively small particles such as sand or mud.
전카본 필터(5)와 후카본 필터(8)는 탄소를 주원료로 하는 활성탄과 같은 것으로서, 원수중에 포함된 염소 성분 입자나 냄새를 제거한다.The all-carbon filter 5 and the fucarbon filter 8 are the same as activated carbon mainly containing carbon, and remove chlorine component particles and odor contained in raw water.
상기 펌프(4)는 원수를 매우 큰 고압으로 원수를 이동시키기 위한 것이다. 이것은 맴브레인 필터(6)의 작동 상태와 관련이 있는 것으로서, 평균 60psi 이상의 압력으로 원수를 공급하여야만 맴브레인 필터(6)에서 정수작용이 이루어지기 때문이다.The pump 4 is for moving the raw water to a very high pressure. This is related to the operation state of the membrane filter 6, since the water purification is performed only in the membrane filter 6 only when the raw water is supplied at a pressure of 60 psi or more on average.
맴브레인 필터(6)는 특히 고압에서 작동되며, 온도에 매우 민감하여 5∼40℃의 온도 범위를 이탈하면 필터가 손상된다.The membrane filter 6 is especially operated at high pressures and is very sensitive to temperature, which will damage the filter if it is outside the temperature range of 5-40 ° C.
본 고안이 다루고자하는 기술은 상기 각종 필터들에 관한 것이다.The technique addressed by the present invention relates to the various filters.
도 2는 종래 필터의 단면도이다.2 is a cross-sectional view of a conventional filter.
도시된 바와 같이 종래의 정수기용 필터(20)는, 필터(21)와 상기 필터(21)를 내부에 설치시키는 케이스(22)로 구성되고, 상기 케이스(22)의 일측에는 필터(21)를 삽입시키기 위한 개구공을 형성하여 상기 개구공을 통해 필터(21)를 삽입시킨후 캡(23)으로 밀봉되게 하였다.As shown in the drawing, the conventional water filter 20 includes a filter 21 and a case 22 for installing the filter 21 therein, and one side of the case 22 includes a filter 21. An opening hole for insertion was formed so that the filter 21 was inserted through the opening hole and then sealed with the cap 23.
케이스(22)에 캡(23)을 결합시키는 방법으로는, 캡(23)을 케이스(22)에 가조립시킨 상태에서 상기 캡(23)을 고속회전시키게 되면, 조립부위가 용융되어 서로 융착되는 스핀융착방법과, 또는 가조립부위의 틈새를 통해 MC 등의 화학물질을 투입시켜 그 화학물질에 의해 서로 융착되어지는 방법이 있다.In the method of coupling the cap 23 to the case 22, when the cap 23 is rotated at a high speed while the cap 23 is temporarily assembled to the case 22, the spins are melted and fused together. There is a fusion method or a method in which chemicals such as MC are introduced through the gap between the temporary assembly parts and fused together by the chemicals.
이러한 융착방법은 케이스(22)로 부터 캡(23)의 분리가 불가능하게 되는 까닭에, 소정시간으로 사용되어지면 필터(20)자체를 폐기하여야 하고, 새로운 필터로 교체시켜야 한다.Since the fusion method is impossible to separate the cap 23 from the case 22, if used for a predetermined time, the filter 20 itself must be discarded and replaced with a new filter.
통상 침전필터의 교환시기는 사용후 3~6개월이고, 선카본필터는 6~12개월이며, 멤브레인필터는 18~24개월이며, 후카본필터는 9~18개월이다.Typically, the replacement time of the precipitation filter is 3 to 6 months after use, the sun carbon filter is 6 to 12 months, the membrane filter is 18 to 24 months, and the after carbon filter is 9 to 18 months.
즉 종래의 정수기용 필터들은 대체로 일회용인 소모품으로 제조되어 일정한 사용시간이 경과되면 필터를 포함한 필터케이스를 페기시켜야 하는 까닭에, 심한 자원낭비를 초래하게 되고, 더불어 폐기된 필터들에 의해 환경공해를 유발하는 등의 문제점을 안게 된다.That is, the conventional water purifier filters are generally made of disposable consumables, and after a certain use time, the filter case including the filter must be discarded, resulting in severe resource waste and environmental pollution by the discarded filters. It causes problems such as causing.
본 고안은 전술한 종래의 문제점을 해결하기 위해서 안출된 것으로서, 본 고안의 목적은 케이스로 부터 필터의 교환을 가능하게 하므로써, 케이스의 반복사용을 가능하게 하고, 이에 따라 원가를 절감하고, 폐기물량을 줄여 환경공해를 일으키지 않도록 한 필터교환용 필터 케이스구조를 제공하는 것을 그 목적으로 한다.The present invention has been made to solve the above-mentioned conventional problems, the object of the present invention is to enable the replacement of the filter from the case, enabling the repeated use of the case, thereby reducing the cost, the amount of waste It is an object of the present invention to provide a filter case structure for filter replacement, which is designed to reduce environmental pollution by reducing the amount of dust.
상기 목적을 달성하기 위한 본 고안의 필터교환용 필터 케이스구조는, 외주에 나사부를 형성한 케이스, 일단에 걸림턱을 형성한 캡, 및 상기 케이스에 형성된 나사부에 나합되는 암나사부와 상기 캡에 형성된 걸림턱에 대향한 계단부을 형성한 체결너트를 구비하고, 케이스와 캡사이에 O링을 개재한 상태에서 상기 체결너트를 조립시키게 되면, 상기 체결너트가 케이스에 나합되면서 캡을 압압하게 되어 밀봉되고, 필터의 교체시에는 상기 체결너트를 사용하여 케이스로 부터 캡을 용이하게해제되도록 한 것을 특징으로 한다.Filter case filter replacement structure of the present invention for achieving the above object is formed on the cap and the female screw threaded to the case formed with a screw portion on the outer periphery, a cap formed with a locking jaw at one end, and a screw portion formed in the case When the fastening nut is provided with a fastening nut having a stepped portion facing the locking jaw, and the fastening nut is assembled with the O-ring interposed between the case and the cap, the fastening nut is sealed to the case while pressing the cap. , When the filter is replaced, the cap is easily released from the case by using the fastening nut.

도시된 바와 같이 본 고안의 필터교환용 필터 케이스구조는, 캡이 결합되는 부위의 외주면에 나사부(22a)를 형성한 케이스(22), 케이스(22)에 접촉되는 부위에 걸림턱(23a)을 형성한 캡(23), 및 상기 케이스(22)에 형성된 나사부(22a)에 나합되는 암나사부(30a)와 상기 캡(23)에 형성된 걸림턱(23a)에 대향한 계단부(30b)을 형성한 체결너트(30)를 구비한다.As shown, the filter case for filter replacement according to the present invention includes a case 22 having a screw portion 22a formed on an outer circumferential surface of a portion at which a cap is coupled, and a catching jaw 23a at a portion contacting the case 22. The formed cap 23 and the female screw portion 30a screwed into the screw portion 22a formed on the case 22 and the stepped portion 30b facing the locking jaw 23a formed on the cap 23 are formed. One fastening nut 30 is provided.
또한 케이스(22)와 캡(23)사이에는 패킹기능을 하는 O링(31)을 개재한다.In addition, an O-ring 31 having a packing function is interposed between the case 22 and the cap 23.
이와 같은 본 고안의 작용 및 효과를 설명한다.This will be described the operation and effect of the present invention.
먼저 케이스(22)의 일측에 형성된 개구공을 통해 필터(21)를 삽입설치하고, 상기 개구공에 O링(31)을 개재시킨다.First, the filter 21 is inserted and installed through an opening formed in one side of the case 22, and an O-ring 31 is interposed in the opening.
이러한 상태에서 상기 O링(31)에 캡(23)을 밀착시키고, 본 고안의 체결너트(30)를 상기 캡(23)을 통해 삽입되게 하여 회전시킨다.In this state, the cap 23 is brought into close contact with the O-ring 31, and the fastening nut 30 of the present invention is inserted through the cap 23 to rotate.
체결너트(30)의 회전에 의해 체결너트의 암나사부(30a)가 케이스의 나사부(22a)에 나합되면서 이동되고, 이에 따라 체결너트의 계단부(30b)이 캡의 걸림턱(23a)에 걸리어 상기 캡(23)을 케이스(22)방향으로 밀게 된다.The female nut part 30a of the fastening nut is screwed into the screw part 22a of the case by the rotation of the fastening nut 30, and accordingly, the step part 30b of the fastening nut hangs on the latching jaw 23a of the cap. The rear cap 23 is pushed toward the case 22.
캡(23)은 그 이동력에 의해 O링(31)을 압압하게 되어 결국 수밀을 유지하면서 캡(23)은 케이스(22)에 결합된다.The cap 23 presses the O-ring 31 by its moving force, and thus the cap 23 is coupled to the case 22 while maintaining watertightness.
한편 이러한 상태로 정수기에 설치되어 사용되어지다가 교체를 요할시에는 체결너트(30)를 반대방향으로 회전시켜 캡(23)을 케이스(22)로 부터 분리시킨후, 케이스(22)내의 필터(21)를 새로운 겻으로 교환설치하면 되는 것이다.On the other hand, when it is installed and used in the water purifier in such a state and needs replacement, the cap 23 is separated from the case 22 by rotating the fastening nut 30 in the opposite direction, and then the filter 21 in the case 22 is removed. ) Can be replaced by a new one.
