한편, 최근에는 합성 섬유의 보급이 증가하고 있다. 그 결과, 폐수와 환경에서 미세 합성 극세사의 양이 확산되어 환경 오염이 더 커지고 있다. 특히 합성 극세사는 생분해성이 없는 합성 섬유의 세탁 과정에서 생산/방출되어 미세 플라스틱에 의한 수질 오염이 더 크다.Meanwhile, the spread of synthetic fibers has been increasing recently. As a result, the amount of fine synthetic microfibers is spreading in wastewater and the environment, leading to greater environmental pollution. In particular, synthetic microfibers are produced and released during the washing process of non-biodegradable synthetic fibers, resulting in greater water pollution due to microplastics.
이와 같이 의류 등의 세탁물에서 배출되는 각종 미세먼지 (미세, 플라스틱, 세탁먼지, 섬유먼지, 황사먼지, 중금속, 방사성 물질, 미세먼지, 기타 유해균 등)가 잔류하게 된 상태로 그대로 외부로 배출되어 환경을 오염시킬 우려가 있다.In this way, various fine dusts (fine, plastic, laundry dust, textile dust, yellow dust, heavy metals, radioactive materials, fine dust, other harmful bacteria, etc.) emitted from laundry such as clothing are discharged to the outside in their remaining state and are discharged into the environment. There is a risk of contamination.

도 8 및 도 9는 본 발명의 다른 실시예에 의한 필터부가 적용된 필터 어셈블리의 단면도들이다.8 and 9 are cross-sectional views of a filter assembly to which a filter unit according to another embodiment of the present invention is applied.
이들 도면을 참조하면, 본 발명에 다른 실시예에 따른 상기 필터 어셈블리(100)는 외부로부터 세척수가 유입된 후 여과되어 배출되도록 유입부(101)와 배출부(102)가 형성되는 제1 필터 케이스(110), 상기 제1 필터 케이스(110)의 내주면으로부터 소정의 간격을 갖도록 이격된 상태로 배치되고 필터부(200)가 결합되는 제2 필터 케이스(120)를 포함하고, 상기 제2 필터 케이스(120)의 필터부(200)는, 필터 어셈블리(100)의 바닥면에 대해서, 상기 제1 필터 케이스(110)의 상측 부위에 배치되어 상기 세척수가 상기 제2 필터 케이스(120)의 필터부(200)에서 여과되는 구조를 포함할 수 있다.Referring to these drawings, the filter assembly 100 according to another embodiment of the present invention includes a first filter case in which an inlet 101 and an outlet 102 are formed so that washing water flows in from the outside and is then filtered and discharged. (110), comprising a second filter case 120 that is disposed at a predetermined distance from the inner peripheral surface of the first filter case 110 and to which the filter unit 200 is coupled, and the second filter case 120 is coupled to the filter unit 200. The filter unit 200 of 120 is disposed at an upper portion of the first filter case 110 with respect to the bottom surface of the filter assembly 100, so that the washing water flows into the filter unit of the second filter case 120. It may include a structure filtered in (200).
전술한 실시예와 달리, 본 실시예에서는 제2 필터 케이스(120)에 배치되는 필터부(200)가 상측 부위에만 배치되어 점에 있다. 즉, 제2 필터 케이스(120) 내부로 유입되는 세척수가 오버플로우(Overflow) 되면서 상기 제1 필터 케이스(110)와 제2 필터 케이스(120)가 상호 이격된 이격공간(G)으로 우회하여 유동하면서 상기 제1 필터 케이스(110)의 배출구(102)로 배출되는 구조로 형성될 수 있다.Unlike the above-described embodiment, in this embodiment, the filter unit 200 disposed in the second filter case 120 is disposed only in the upper portion. That is, as the washing water flowing into the second filter case 120 overflows, the first filter case 110 and the second filter case 120 detour into the space G where they are spaced apart from each other. It may be formed in a structure to be discharged through the outlet 102 of the first filter case 110 while doing so.
이하, 전술한 본 발명에 따른 필터 어셈블리(100)에 의하여 여과되는 과정을 첨부된 도면과 함께 설명한다.Hereinafter, the filtration process by the filter assembly 100 according to the present invention described above will be described with the accompanying drawings.
도 13 및 도 14는 본 발명의 일 실시예에 의한 필터 어셈블리와 잔수 방지 구조를 나타내는 확대 도면이고, 도 15 및 도 16은 본 발명의 일 실시예에 의한 필터 케이스와 이탈 방지 구조를 나타내는 확대 도면이 도시되어 있다. 13 and 14 are enlarged views showing a filter assembly and a water retention prevention structure according to an embodiment of the present invention, and FIGS. 15 and 16 are enlarged views showing a filter case and a separation prevention structure according to an embodiment of the present invention. This is shown.
이들 도면을 참조하여 설명하면, 먼저 세탁기(10)의 세탁조에 세척수가 공급된다. 투입되는 상기 세척수는 의류 등의 세정이 완료된 후에 배관 또는 호스를 통하여 세탁기(10)의 외부로 배출된다. 상기 세탁조에서 배출되는 상기 세척수는 세탁기(10)의 내측 하부, 측면, 세탁기 외부 등에 형성되는 본 발명에 따른 필터 어셈블리(100)로 유입되며 외부로 배출되기 전에 여과된다. 이때, 필터 어셈블리(100)에는 전술한 필터부(200)가 형성되는 필터 케이스(110, 120)가 배치되어 있으므로, 상기 세척조에서 배출된 후에 유입되는 상기 세척수는 상기 필터부(200)를 경유하며 미세한 섬유 플라스틱이 여과될 수 있게 된다.When described with reference to these drawings, first, washing water is supplied to the washing tank of the washing machine 10. The injected washing water is discharged to the outside of the washing machine 10 through a pipe or hose after the washing of clothes, etc. is completed. The washing water discharged from the washing tub flows into the filter assembly 100 according to the present invention formed on the inner bottom, side, or outside of the washing machine 10, and is filtered before being discharged to the outside. At this time, since the filter cases 110 and 120 in which the above-described filter unit 200 is formed are disposed in the filter assembly 100, the washing water flowing in after being discharged from the washing tank passes through the filter unit 200. Fine fibrous plastics can be filtered out.
즉, 필터 어셈블리(100)의 제1 필터 케이스(110) 측면 중간 부위에 형성되는 유입부(101)를 통하여 상기 세척수가 세척조로부터 배출된 후 유입된다. 유입된 상기 세척수는 제2 필터 케이스(120)의 내부에 형성되는 미세 플라스틱의 여과가 가능한 필터부(200)를 통과하며 필터링된 후에 제2 필터 케이스(120) 하측에 형성되는 배출부(102)를 통하여 외부로 배출되게 된다. 이 때, 제2 필터 케이스(120)의 상측 부위에 배치되는 필터부(200)를 통하여 여과된 세척수는 상기 제1 필터 케이스(110)와 제2 필터 케이스(120)의 사이에 형성되는 이격 공간(G)을 경유하여 배출부(102)로 배출되고, 제2 필터 케이스(120)의 하측 부위에 적층되어 있는 복수의 필터부(200)를 통하여 여과된 세척수는 제2 필터 케이스(120)의 하부에 소정의 간격으로 형성되는 복수의 유동홀(129)을 통하여 배출부(102)로 배출된다.That is, the washing water is discharged from the washing tank and then introduced through the inlet 101 formed in the middle portion of the side of the first filter case 110 of the filter assembly 100. The introduced washing water passes through the filter unit 200 formed inside the second filter case 120 capable of filtering microplastics, and after being filtered, the discharge unit 102 formed on the lower side of the second filter case 120. It is discharged to the outside through . At this time, the washing water filtered through the filter unit 200 disposed on the upper part of the second filter case 120 is stored in the separation space formed between the first filter case 110 and the second filter case 120. The washing water is discharged to the discharge unit 102 via (G) and filtered through the plurality of filter units 200 stacked on the lower part of the second filter case 120. It is discharged to the discharge unit 102 through a plurality of flow holes 129 formed at predetermined intervals in the lower part.
이러한 여과 과정에서, 제2 필터 케이스(120)에 배치되는 필터부(200)의 외측면 부위에는 상기 세척수에서 용출되는 미세한 섬유 플라스틱이 축적되어 스케일(scale)이 형성될 수 있다. 이때, 제2 필터 케이스(120) 내에서 유동하는 상기 세척수 중 일부가 상측에 배치되는 필터부(200) 방향으로 하측에서 상측 방향으로 오버플로우(Oveflow) 되면서 상부측 여과 방식으로 여과된 후에 상기 제1 필터 케이스(110)와 제2 필터 케이스(120)의 사이에 형성되는 이격 공간(G)을 통하여 배출되도록 함으로써, 필터부(200)에 상기 스케일 등이 축적되는 현상을 최소화할 수 있다.During this filtration process, fine fiber plastic eluted from the washing water may accumulate on the outer surface of the filter unit 200 disposed in the second filter case 120 to form scale. At this time, some of the washing water flowing in the second filter case 120 overflows from the bottom to the top in the direction of the filter unit 200 disposed at the top and is filtered by the upper filtration method. By discharging through the separation space G formed between the first filter case 110 and the second filter case 120, the accumulation of scale in the filter unit 200 can be minimized.
