본 발명은 필터조립체에 관한 것으로, 보다 상세하게는 비데와 같은 생활 수처리기기에 사용되는 필터조립체에 관한 것이다.The present invention relates to a filter assembly, and more particularly, to a filter assembly used in domestic water treatment equipment such as a bidet.

정수기나 비데장치 등의 이른바 가정용 수처리기기는 상수원을 여과하여 공급함으로써 가정에서 식수 또는 세척수를 안전하게 활용하기 위한 것으로, 특히 비데장치는 근래에 들어 그 보급이 급속히 확대되고 있다.The so-called household water treatment equipment such as a water purifier and a bidet device is for safely utilizing drinking water or washing water at home by filtering and supplying a water source. In particular, the bidet device has recently been rapidly expanding in popularity.

일반적으로 비데장치는 좌변기의 좌대에서 자동인출되도록 구성된 분사노즐과, 상수도관 등의 원수공급관과 연결된 필터조립체, 콘트롤패널 등을 포함하여 이루어져 있다. In general, a bidet device includes a spray nozzle configured to be automatically withdrawn from the left side of the toilet seat, a filter assembly and a control panel connected to a raw water supply pipe such as a water supply pipe.

여기서, 필터조립체는 입수구와 출수구의 위치에 따라 양방향식과 단방향식으로 구분되는데, 양방향식은 입수구와 출수구가 서로 반대편에 있는 것이며, 단방향식은 입수구와 출수구가 동일측면에 배치된 것이다.Here, the filter assembly is divided into two-way and one-way according to the position of the inlet and outlet, the bidirectional type is the inlet and the outlet are opposite to each other, the one-way type is the inlet and the outlet are arranged on the same side.

도 1에 나타난 것과 같이 양방향 필터조립체(10)는 원수공급관(20)과 분기밸브(22)를 통해 입수구(101)가 연결되고, 출수구(102) 측에 분사노즐(5)로 정수를 공급하는 정수공급관(24)이 연결된 구조로 장착되어 있다.As shown in FIG. 1, the bidirectional filter assembly 10 is connected to an inlet 101 through a raw water supply pipe 20 and a branch valve 22, and supplies purified water to the injection nozzle 5 on the outlet 102 side. The purified water supply pipe 24 is connected in a structure.

이와 같은 양방향식 필터조립체에 의하면 원수공급관(20)에서 공급된 원수가 입수구(101)를 통해 필터조립체(10) 내로 유입되어 출수구(102) 측으로 이동하면서 내부의 필터소자에 의해 여과된 다음 출수구(102)를 통해 배출되어 정수공급관(24)을 통해 분사노즐(5)로 공급된다.According to the bidirectional filter assembly as described above, the raw water supplied from the raw water supply pipe 20 is introduced into the filter assembly 10 through the inlet 101 and moved to the outlet 102 to be filtered by the internal filter element, and then the outlet port ( Discharged through the 102 is supplied to the injection nozzle (5) through the purified water supply pipe (24).

이러한 종래의 양방향식 필터조립체는 그 구성이 비교적 간단하나, 교체작업을 수행함에 있어 필터조립체(10)의 입수구(101)와 출수구(102)가 서로 반대방향으로 형성되어 있기 때문에, 필터조립체(10)의 교체시, 입수구(101)와 분기밸브(22) 및 출수구(102)와 정수공급관(24)의 연결구성을 해체하여야 하며, 마찬가지로 새로운 필터조립체를 장착하는 경우에도 입수구(101)측과 출수구(102)측에서 분기밸브 (22)및 정수공급관(24)과의 연결작업을 각각 수행하여야 하므로, 그 작업이 번거롭다는 문제점이 있다. The conventional bidirectional filter assembly has a relatively simple configuration, but in order to perform a replacement operation, since the inlet 101 and the outlet 102 of the filter assembly 10 are formed in opposite directions, the filter assembly 10 ), The inlet port 101, the branch valve 22, the outlet port 102 and the water supply pipe 24 should be dismantled.In the case of installing a new filter assembly, the inlet port 101 side and the outlet port should be removed. Since the connection work with the branch valve 22 and the purified water supply pipe 24 must be performed at the side 102, the work is cumbersome.

그리고, 도 2에 나타난 것과 같이 단방향 필터조립체(30)는, 일측에 통유포트(321)가 형성된 케이싱(32)과, 이에 내장된 필터캐니스터(34)로 구성되어 있는데, 필터캐니스터(34)에는 필터소자(36)가 내재되어 있다. As shown in FIG. 2, the unidirectional filter assembly 30 includes a casing 32 having an oil passage port 321 formed at one side thereof, and a filter canister 34 embedded therein, which includes a filter canister 34. The filter element 36 is inherent.

상기 케이싱(32)에 형성된 통유포트(321)는 입수구와 출수구의 역할을 동시에 하는 것이며, 케이싱(32) 내에는 통유포트(321)를 통해 유입된 원수의 흐름을 제어하는 유로전환어댑터(38)가 구비되어 있다.The oil supply port 321 formed in the casing 32 serves as an inlet and an outlet at the same time, and a flow path switching adapter 38 for controlling the flow of raw water introduced through the oil supply port 321 in the casing 32. Is provided.

이러한 종래의 단방향 필터조립체는, 원수공급관(20)에 장착된 분기밸브(23)에 통유포트(321)가 연결되는 방식으로 부착되며(도 3 참조), 통유포트(321)를 통해 유입된 원수가 유로전환어댑터(38)를 거치면서 케이싱(32)과 필터캐니스터(34) 사이의 간극으로 유입됨 다음, 필터캐니스터(34) 하단을 통해 필터캐니스터 내부로 유입되어 필터소자(36)를 거치면서 여과되고, 계속해서 필터캐니스터(34) 외부로 배출된다.The conventional one-way filter assembly is attached in such a way that the oil supply port 321 is connected to the branch valve 23 mounted on the raw water supply pipe 20 (see FIG. 3), and the raw water introduced through the oil supply port 321. Flows into the gap between the casing 32 and the filter canister 34 while passing through the flow path switching adapter 38, and then flows into the filter canister through the bottom of the filter canister 34 and passes through the filter element 36. It is filtered and then discharged out of the filter canister 34.

필터캐니스터(34) 외부로 배출된 정수는 통유포트(321)를 통해 분기밸브(23)로 유입된 다음 정수공급관(24)으로 유동된다.The purified water discharged out of the filter canister 34 flows into the branch valve 23 through the oil supply port 321 and then flows into the purified water supply pipe 24.

이와 같은 단방향 필터조립체는 입수구와 출수구가 하나의 통유포트(321)에 통합구성되어 있기 때문에 그 교체작업이 간단하다는 특징이 있다. Such a unidirectional filter assembly is characterized in that the replacement operation is simple because the inlet and outlet are integrated in one oil supply port 321.

그러나, 상술한 바와 같은 종래의 단방향 필터조립체(30)는 케이싱(32)과 필터캐니스터(34) 및 유로전환어댑터(38)가 조합된 복잡한 구조로서 제작비용이 높고, 특히 직접적으로 여과작용을 행하는 구성요소는 필터캐니스터(34)임에도 불구하고, 필터캐니스터(34)만 교체할 수 없고, 케이싱(32) 및 유로전환어댑터(38)를 포함한 필터조립체 전체를 일괄교체해야 하기 때문에 비데장치의 유지관리에 필요한 소모품교체 비용 또한 높아진다는 문제점이 있다.However, the conventional unidirectional filter assembly 30 as described above is a complicated structure in which the casing 32, the filter canister 34 and the flow path adapter 38 are combined, and the manufacturing cost is high. Although the component is the filter canister 34, maintenance of the bidet device is not possible because only the filter canister 34 can be replaced, and the entire filter assembly including the casing 32 and the flow path adapter 38 must be replaced. The cost of replacing consumables is also high.

또한, 하나의 통유포트(321)가 입수구와 출수구 역할을 모두 하기 위해서는, 분기밸브(23)와 같은 별도의 복잡한 구성요소를 필요로하기 때문에 결과적으로 비데장치의 제작단가가 높아진다는 문제점이 있다. In addition, since one oil supply port 321 serves as both an inlet and an outlet, a separate complicated component such as a branch valve 23 is required, and as a result, a manufacturing cost of the bidet device is increased.

본 발명은 상기한 종래 문제점을 해결하고자 안출된 것으로, 구조가 간단하여 교체작업이 간단할 뿐만 아니라, 생산단가가 낮아지고, 여과작용을 직접수행하는 구성요소만을 교체할 수 있게 됨으로써 소모품 교체에 따른 유지관리 비용이 절 감되는 수처리기기의 필터조립체 제공을 목적으로 한다.The present invention has been made to solve the above-mentioned conventional problems, the structure is simple, the replacement operation is not only simple, the production cost is lowered, it is possible to replace only the components that directly perform the filtration action according to the consumable replacement The aim is to provide a filter assembly for water treatment equipment that reduces maintenance costs.

상기 필터캡은 원수공급관과 연결되어 원수가 유입되는 입수포트가 측면에 구비되고, 정수공급관과 연결되는 출수포트가 상면에 구비되며, 하면이 개방된 구조로 이루어진다.The filter cap is connected to the raw water supply pipe is provided with an inlet port for introducing the raw water on the side, the outlet port connected to the purified water supply pipe is provided on the upper surface, the lower surface is made of an open structure.

필터카트리지는 필터소자가 내장되며, 상면이 개방되고, 상단 측면에 다수개의 입수홀이 형성된 구조로서, 입수홀을 포함한 상단이 필터캡의 하면으로 인입되어 필터캡과 분리 가능하게 결합됨으로써 입수포트와 입수홀이 연통되고, 개방된 상면이 출수포트와 연통되는 구조로 이루어진다. The filter cartridge has a built-in filter element, a top surface is opened, and a plurality of inlet holes are formed on the upper side, and the top including the inlet hole is introduced into the bottom of the filter cap to be detachably coupled with the inlet port. The inlet hole communicates with each other, and the open upper surface is in communication with the outlet port.

이와 같은 본 실시예에 따른 필터조립체에는, 필터캡(42)의 개방된 하면을 통해 필터카트리지(44)의 삽입부(441)가 삽입되어 걸림돌기부(442)가 걸림슬롯(42a)에 끼워지는 방식으로 필터캡(42)과 필터카트리지(44)가 결합되며, 필터캡(42)과 필터카트리지(44)가 결합된 상태에서 상하부오링(46)(47)이 필터캡(42)의 내면과 필터카트리지(44)의 외면 사이에서 밀착됨으로써 필터캡(42)의 입수포트(421)에서 필터카트리지(44)의 입수홀(44a)로 이어지는 이른바 입수유로를 형성하게 된다. In such a filter assembly according to the present embodiment, the insertion portion 441 of the filter cartridge 44 is inserted through the open lower surface of the filter cap 42 so that the locking projection 442 is fitted into the locking slot 42a. The filter cap 42 and the filter cartridge 44 are coupled to each other, and the upper and lower o-rings 46 and 47 are connected to the inner surface of the filter cap 42 while the filter cap 42 and the filter cartridge 44 are coupled to each other. By being in close contact between the outer surfaces of the filter cartridge 44 to form a so-called inflow passage leading from the inlet port 421 of the filter cap 42 to the inlet hole 44a of the filter cartridge 44.

그리고, 필터카트리지(44)의 상단이 필터캡(42)의 상단 내면에 밀착됨으로써 필터카트리지(44) 내부로부터 필터캡(42)의 출수포트(422)로 이어지는 출수유로를 형성하게 된다.Then, the upper end of the filter cartridge 44 is in close contact with the inner surface of the upper end of the filter cap 42 to form a water discharge passage leading from the inside of the filter cartridge 44 to the outlet port 422 of the filter cap 42.

여기서, 상부오링(46)의 경우 필터카트리지(44)의 받침부(443)에 의해 그 저면이 지지된 상태에서 필터캡(42)의 소직경부(424)에 의해 위로부터 강하게 압착되기 때문에 필터캡(42)과 필터카트리지(44) 사이 간극에 대한 밀폐기능이 더욱 강화 되며, 특히 입수포트(421)를 통해 유입된 원수의 압력이 상방으로는 받침부(443)에 의해 1차적으로 차단되기 때문에 상부오링(46)에 의한 실링상태가 견고하게 유지된다.Here, in the case of the upper O-ring 46, the filter cap is strongly pressed from above by the small diameter portion 424 of the filter cap 42 while the bottom surface thereof is supported by the support portion 443 of the filter cartridge 44. The sealing function for the gap between the 42 and the filter cartridge 44 is further strengthened, and in particular, since the pressure of the raw water introduced through the inlet port 421 is primarily blocked by the support part 443 upwards. The sealing state by the upper o-ring 46 is maintained firmly.

또한, 하부오링(47)은 필터카트리지(44)의 삽입부(441)와 그 아래부분의 외경이 다른 형태적인 특성상 삽입부(441) 아래부분에 의해 지지되고 있기 때문에 원수의 유입압력에 의해 아래로 밀려내려가지 않는다.In addition, the lower O-ring 47 is supported by the lower portion of the insert portion 441 due to the different shape of the outer diameter of the insert portion 441 and the lower portion of the filter cartridge 44, Not pushed back.

따라서, 본 실시예에 의한 필터조립체의 여과작동은, 필터캡(42)과 필터카트리지(44)가 결합된 상태에서 입수포트(421)를 통해 유입된 원수가 입수수로를 따라서 유동되면서 각 입수홀(44a)을 통해 필터카트리지(44)의 내부로 유입되며, 유입된 원수는 필터소자(50)를 거치면서 여과된 다음, 출수포트(422)를 통해 배출됨으로써, 출수포트(422)와 연결된 정수공급관(24)측으로 유동하는 방식으로 이루어진다.Therefore, in the filtration operation of the filter assembly according to the present embodiment, the raw water introduced through the inlet port 421 in the state in which the filter cap 42 and the filter cartridge 44 are coupled to each inlet hole flows along the inlet channel. Through the 44 (44a) is introduced into the filter cartridge 44, the introduced raw water is filtered through the filter element 50, and then discharged through the water outlet port 422, the purified water connected to the water outlet port 422 It is made to flow to the supply pipe 24 side.

그리고, 본 실시예에 따르면, 사용기한이 지난 필터소자(50)를 교체하는 경우에, 원수공급관(20)과 정수공급관(24)이 필터캡(42)으로만 연결되는 구조특성상, 원수공급관(20)상에 구비된 분기밸브(22)를 잠그는 등의 방법으로 필터조립체(40) 측으로 공급되는 원수를 차단한 다음, 필터소자(50)가 내장된 필터카트리지(44)만을 새것으로 교체하면 된다.And, according to this embodiment, in the case of replacing the filter element 50, which has expired, the raw water supply pipe 20 and the purified water supply pipe 24 is connected to only the filter cap 42, the raw water supply pipe ( 20. The raw water supplied to the filter assembly 40 is shut off by, for example, locking the branch valve 22 provided thereon, and then only the filter cartridge 44 in which the filter element 50 is built is replaced with a new one. .

따라서, 소모품의 교체작업이 간단할 뿐만 아니라, 소모되는 구성요소가 간단한 구조의 필터카트리지(44)로 한정되기 때문에 소모품 교체비용이 종래에 비해 크게 절감된다.Therefore, not only the replacement of the consumables is simple, but also the consumable components are limited to the filter cartridge 44 having a simple structure, thereby greatly reducing the consumable replacement cost.

이상에서 살펴본 바와 같은 본 발명에 따른 수처리기기의 필터조립체에 의하면, 구조가 간단하여 교체작업이 간단할 뿐만 아니라, 생산단가가 낮아지고, 여과작용을 직접수행하는 구성요소만을 교체할 수 있게 됨으로써 소모품 교체에 따른 유지관리 비용이 절감된다는 이점이 있다.According to the filter assembly of the water treatment device according to the present invention as described above, not only the replacement operation is simple because of its simple structure, but also the production cost is lowered, and only the components that directly perform the filtration action can be replaced.
