상기의 이물걸름장치는 탈수조(20) 내측벽에 고정되는 필터케이스(30)와 이의 내측에 착탈되는 필터(32)로 구성되며, 필터(32)는 상부측으로 손잡이부(34a)를 갖는 프론트 커버(34) 및 이에 힌지결합되는 리어 커버(36)로 이루어지고, 프론트 및 리어 커버(34)(36) 일면에는 세탁수를 탈수조(20) 내부로 배출시킴과 동시에 이물을 거르기 위해 걸름망(38)(40)이 각각 부착되어 있다.The foreign matter trapping device is composed of a filter case 30 fixed to the inner wall of the dehydration tank 20 and a filter 32 detachable from the inside thereof, and the filter 32 has a front portion having a handle portion 34a at an upper side thereof. A cover 34 and a rear cover 36 hinged thereto, and the front and rear covers 34 and 36 have one screen for discharging the washing water into the dehydration tank 20 and at the same time filtering the foreign matter. 38 and 40 are respectively attached.

프론트 및 리어 커버(34)(36) 사이에는 채집된 이물질이 외부로 배출되는 것을 방지할 수 있도록 체크 밸브(42)가 장착되어 있으며, 이 체크 밸브(42)는 세탁수의 배수시 필터(32)내에 채집된 이물질의 배출을 방지하는 역류 방지부(42a)와 이 역류 방지부(42a) 일단측에 구비되어 리어 커버(36)에 형성되어 있는 슬릿공(36a)에 삽입 고정되는 다수의 고정부(42b) 및 이 고정부의 단부에 부착되어 상기 고정부(42b)를 슬릿공(36a)으로 삽입시킬 수 있도록 하기 위한 안내판(42c)으로 이루어져 있다.A check valve 42 is installed between the front and rear covers 34 and 36 to prevent the collected foreign matter from being discharged to the outside. The check valve 42 is a filter 32 for draining the wash water. ), A plurality of high flow prevention parts 42a for preventing the discharge of foreign matter collected in the inner part and a plurality of high-mounted pieces inserted into and fixed to the slit holes 36a formed on the rear cover 36 are provided at one end of the reverse flow prevention part 42a. A guide plate 42c is attached to an end portion 42b and an end portion of the fixing portion so that the fixing portion 42b can be inserted into the slit hole 36a.

이와 같이 구성된 종래의 전자동 세탁기는 본체(10) 상부에 마련된 도어(도시되지않음)를 개방한 다음, 탈수조(20)내에 세탁물 및 세제를 넣은 다음 급수구(24)를 통하여 일정량의 세탁수를 급수한 상태에서 구동모터(14)를 작동시키면, 구동모터(14)의 구동력이 벨트(16)에 의해 동력전달장치(18)로 전달되고, 이와 동시에 동력전달장치(18)에서는 회전력을 감속시킨 후 펄세이터(26)를 회전시켜 탈수조(20) 내에 수류를 만든다.The conventional fully automatic washing machine configured as described above opens a door (not shown) provided at an upper portion of the main body 10, and then puts laundry and detergent into the dehydration tank 20, and then supplies a certain amount of washing water through the water supply port 24. When the driving motor 14 is operated in a water supply state, the driving force of the driving motor 14 is transmitted to the power transmission device 18 by the belt 16, and at the same time, the power transmission device 18 reduces the rotational force. After rotating the pulsator 26 to create a water flow in the dehydration tank (20).

즉, 펄세이터(26)의 회전에 따라 탈수조(20)내에 급수된 세탁수가 원심력에 의해 상하수류를 만들어 세탁행정을 수행한다. 이때, 수류는 탈수조(20) 내측벽으로 밀림과 동시에 필터 케이스(30)의 유입구를 따라 상승되면서 프론트 및 리어 커버(34)(36)에 부착된 걸름망(38)(40)과 필터 케이스(30)의 유출공(30a)을 통하여 탈수조(20) 측으로 배출되고, 프론트 및 리어 커버(34)(36) 내부에 채집된 이물질은 상부로 밀어 올려져 필터(32)의 상부로부터 하부쪽으로 채집상태가 진행된다.That is, the washing water supplied in the dehydration tank 20 in accordance with the rotation of the pulsator 26 creates a water flow up and down by centrifugal force to perform the washing process. At this time, the water flow is pushed to the inner wall of the dehydration tank 20 and at the same time as it rises along the inlet of the filter case 30 and the filter net 38 and 40 and the filter case (attached to the front and rear covers 34 and 36). 30 is discharged to the dehydration tank 20 through the outlet hole 30a, and the foreign matter collected in the front and rear covers 34 and 36 is pushed upward and collected from the top of the filter 32 toward the bottom. The state proceeds.

그 후, 세탁종료 후 배수시에는 필터(32)의 유입구를 통해 역으로 배출되는 세탁수의 분출압에 의해 리어 커버(36) 내주면에 일단부가 접촉되도록 휘어진 체크밸브(42)의 역류 방지부(42a)가 초기상태로 복귀되면서 이물질이 탈수조(20) 내부로 유출되는 것을 차단함에 따라 이물질이 차례로 적층되고, 오염된 세탁수는 배수구(28)를 통해 배수된다.Then, when the drainage after the end of washing, the reverse flow prevention portion of the check valve 42 is bent so that one end is in contact with the inner circumferential surface of the rear cover 36 by the ejection pressure of the washing water discharged back through the inlet of the filter 32 ( As 42a) is returned to the initial state, the foreign matter is stacked in order as the foreign matter is prevented from leaking into the dehydration tank 20, and the contaminated washing water is drained through the drain hole 28.

그리고, 배수가 완료되면 다시 급수구(24)를 통해 헹굼용 세탁수가 헹굼에 필요한 수위까지 급수되어 전술한 세탁행정과 같이 동력전달장치(18)의 구동력에 의해 펄세이터(26)가 시계, 반시계방향으로 회전을 반복하면서 세탁물에 스며 있는 오염물 및 세제를 헹구어 낸다.When the drainage is completed, the washing water for rinsing is again supplied to the water level required for rinsing through the water supply port 24, and the pulsator 26 is clocked and counterclockwise by the driving force of the power transmission device 18 as described above. Rinse the dirt and detergent from the laundry while rotating in the direction.

이와같이 행굼행정을 다수회 반복하여 최종 헹굼행정이 종료되면, 외조(12) 및 탈수조(20)내에 저장된 세탁수는 배수구(28)를 통하여 배수되고, 다시 동력전달 장치(18)가 일방향으로 고속 회전하면서 세탁물에 스며있는 세탁수를 탈수한다.In this way, when the final rinsing stroke is completed by repeating the rinsing cycle a plurality of times, the wash water stored in the outer tub 12 and the dehydrating tank 20 is drained through the drain hole 28, and the power transmission device 18 is then driven at a high speed in one direction. Dehydrate the wash water that permeates the laundry while rotating.

그러나, 상기와 같이 필터케이스의 유입구를 따라 상승되는 수류가 필터로 유입됨과 동시에 프론트 및 리어커버 전,후면에 부착되어 있는 걸름망을 통해 탈수조 측으로 배출되었기 때문에 탈수조로 배출되는 수류의 압력이 약함에 따라 세탁물에 묻어 있는 이물질을 확실하게 제거할 수 없어 세탁효율이 저하되는 문제점이 있었다.However, since the water flow rising along the inlet of the filter case is introduced into the filter as described above and discharged to the dehydration tank side through the filter net attached to the front and rear covers, the pressure of the water flow discharged to the dehydration tank is weak. Accordingly, there was a problem in that the laundry efficiency could not be reliably removed from the laundry.

본 발명은 상기와 같은 문제점을 해결하기 위한 것으로서, 본 발명의 목적은 탈수조와 이에 설치된 필터케이스 사이에 형성된 유로를 따라 상승되는 수류를 폭포수류로 전환시켜 탈수조 내부로 배출시킬 수 있도록 프론트커버의 구조를 변경함으로써, 세탁물의 세탁행정시 세탁효율을 증대시킬 수 있는 세탁기의 이물걸름장치를 제공하는데 있다.The present invention is to solve the above problems, an object of the present invention is to convert the water flows along the flow path formed between the dehydration tank and the filter case installed therein to the waterfall flows to discharge the inside of the dehydration tank of the front cover By changing the structure, to provide a foreign matter trapping device of the washing machine that can increase the washing efficiency in the laundry administration of the laundry.

That is, the rear cover 70 is coupled to the hinge hole 68a of the front cover 68 while being coupled to the rear cover 70 so as to be detachably mounted to the square hole 60a of the filter case 60.

그 후, 구동모터(14)를 작동시키면 이의 구동력이 동력전달장치(18)로 전달됨에 따라 탈수조(20) 바닥면에 내설된 펄세이터(26)를 회전시켜 수류를 만들면서 세탁행정을 개시한다. 즉, 펄세이터(26)의 회전에 따른 원심력에 의해 만들어진 수류는 탈수조(20) 내측벽으로 밀리면서 필터케이스(60)의 유입공(60b)을 따라 상승되어 프론트 및 리어커버(68)(70)에 부착된 걸름망(64)(66)을 통해 탈수조(20)측으로 배출되고, 이와 동시에 탈수조(20)와 필터케이스(60) 사이에 형성된 유로(P)를 따라 상승된 수류는 프론트커버(68)에 마련된 배출공(68b)을 통과하면서 폭포수류로 전환되어 세탁효율을 증대시킬 수 있는 것이다.Thereafter, when the driving motor 14 is operated, the driving force thereof is transmitted to the power transmission device 18 to rotate the pulsator 26 built in the bottom surface of the dehydration tank 20 to start the washing operation while making water flow. do. That is, the water flow generated by the centrifugal force due to the rotation of the pulsator 26 is raised along the inlet hole 60b of the filter case 60 while being pushed to the inner wall of the dehydration tank 20, so that the front and rear covers 68 ( 70 is discharged to the dehydration tank 20 through the sieves 64 and 66 attached to 70, and at the same time, the flow of water flowing along the flow path P formed between the dehydration tank 20 and the filter case 60 is While passing through the discharge hole (68b) provided in the cover 68 is converted to the waterfall flow can increase the washing efficiency.

이때, 리어커버(70)의 수용흠(70a)에 끼워진 체크밸브(78)는 수류의 상승압에 의해 리어커버(70) 내면으로 휘어지게 되어 세탁물에서 생성된 이물질을 채집하는 것이다.At this time, the check valve 78 fitted to the receiving flaw 70a of the rear cover 70 is bent to the inner surface of the rear cover 70 by the upward pressure of the water flow to collect foreign substances generated in the laundry.

그리고, 세탁행정이 종료되어 세탁수를 배수하면 필터(62)의 유입구를 통해 역으로 배출되는 세탁수의 분출압에 의해 리어커버(70) 내주면에 접촉된 체크밸브(78)가 초기상태로 복귀되면서 이물질이 탈수조(20) 내부로 다시 유출되는 것을 차단하고, 배수가 완료되면 급수구(24)를 통해 세탁수를 공급한 후 헹굼행정 및 탈수행정을 순차적으로 수행하여 세탁수를 탈수한다.When the washing operation is finished and the washing water is drained, the check valve 78 in contact with the inner circumferential surface of the rear cover 70 is returned to the initial state by the ejection pressure of the washing water discharged back through the inlet of the filter 62. While blocking foreign matters from leaking back into the dehydration tank 20, and when the drainage is completed, the washing water is supplied through the water supply port 24, and then rinsing and dehydrating strokes are sequentially performed to dehydrate the wash water.

또한, 탈수행정 후 필터(62)내에 채집된 이물질을 제거할 때에는 필터케이스(60)의 삽입공(60c)으로 손가락을 넣은 다음 가압하면 프론트커버(68)의 록킹부(74)가 하방향으로 밀리면서 록킹이 해제되어 필터케이스(60)에 대해 전방으로 필터(62)를 쉽게 분리할 수 있고, 프론트커버(68)에 결합된 리어커버(70)를 열어 이물질을 간단하게 제거할 수 있는 것이다.In addition, in order to remove the foreign matter collected in the filter 62 after the dehydration stroke, if the finger is inserted into the insertion hole 60c of the filter case 60 and pressurized, the locking portion 74 of the front cover 68 moves downward. The locking is released while being pushed so that the filter 62 can be easily separated from the front of the filter case 60, and the rear cover 70 coupled to the front cover 68 can be easily removed to remove foreign substances. .

이상에서와 같이 본 발명에 따른 세탁기의 이물걸름장치에 의하면, 탈수조와 이에 설치된 필터케이스 사이에 형성된 유로를 따라 상승되는 수류를 폭포수류로 전환시켜 탈수조 내부로 배출시킬 수 있도록 프론트커버의 구조를 변경하여 세탁물의 세탁행정시 세탁물에 묻어 있는 이물질이 확실하게 제거되므로 세탁효율을 증대시킬 수 있다.According to the foreign matter trapping device of the washing machine according to the present invention as described above, the structure of the front cover to convert the water flows along the flow path formed between the dehydration tank and the filter case installed therein into a waterfall flow to discharge into the dehydration tank By changing it, the foreign matter on the laundry is surely removed during the laundry administration of the laundry, thereby increasing the washing efficiency.
