(20) and the filter member (5) is detachably inserted into the filter case (20) to filter the bulky foreign matter from entering the drain pumping motor (not shown) in the contaminated water passing through the filter case (5). ) And a lid detachably lockable to the opening of the filter case 20 via a packing 6 so as to recover the foreign matters filtered by the filter member 5 to the outside of the washing machine body 1. 7 and foldable hinges in the openings of the filter case 20 to receive the flow of foreign matter remaining in the filter member 5 when the filter member 5 is separated, and at the same time to induce the flow of residual water. Consists of a conductive member (30).

즉, 상기 필터케이스(20)는 그 전측단을 통하여 상기 필터부재(5)가 삽입안착되도록 형성된 내경부(20a)와, 상기 내경부(20a)의 전측단에 상기 팩킹(6)을 매개로 뚜껑(7)이 삽입안착되도록 외측으로 형성된 단턱(20b)과, 상기 내경부(20a)와 상기 제1배수호스(2)가 연통되게 연결조립되도록 둘레의 일측에 돌출형성된 제1통수로(20c)와, 상기 내경부(20a)와 상기 제2배수호스(3)가 연통되게 연결조립되도록 후측단하부에 돌출형성된 제2통수로(20d)와, 상기 내경수(20a)의 후측단 상부에 연통되게 돌출형성되어 압력센싱수단(8)과 연결조립되는 제3통수로(20c)로 이루어져 있다.That is, the filter case 20 has an inner diameter portion 20a formed so that the filter member 5 is inserted and seated through the front end portion thereof, and the packing 6 is connected to the front end portion of the inner diameter portion 20a. A first channel 20c protruding to one side of the circumference so that the lid 7 is inserted into and seated outside the step 20b and the inner diameter portion 20a and the first drain hose 2 are connected and assembled. ), A second water passage 20d protruding from the rear end lower portion so that the inner diameter portion 20a and the second drain hose 3 communicate with each other, and an upper portion of the rear end portion of the inner diameter water 20a. It is formed in communication with the third channel 20c which is connected to and assembled with the pressure sensing means (8).

이때, 상기 제2통수로(20d)는 단턱(20b)의 높이보다 낮은 위치에서 내경부(20a)의 바닥면과 동일한 높이에 형성되어 있다.At this time, the second channel 20d is formed at the same height as the bottom surface of the inner diameter portion 20a at a position lower than the height of the step 20b.

한편, 상기 잔수유도부재(30)는 그 중앙이 하부측으로 오목하게 만곡형성되어서 그 후단양측이 상기 필터케이스(20)의 단턱(20b)에 힌지핀(31)을 매개로 절첩가능케 장착되어 있다.On the other hand, the residual water inducing member 30 is formed to be curved concave to the lower side, the rear end both sides of the filter case 20 is attached to the stepped through the hinge pin (31) via the hinge pin (31). .

즉, 잔수유도부재(30)는 비사용시 필터케이스(20)의 개구를 폐쇄하는 덮개(11)에 의해 덮개(11)와 뚜껑에(7)의 사이 단턱(20b)에 세워져 보관되고, 사용시에는 필터케이스(20)의 개구에서 개방되는 덮개(11)에 의해 수평으로 경사지게 설치되어 잔수의 흐름을 유도하도록 절첩되어 진다.That is, the residual water inducing member 30 is kept standing on the step 20b between the lid 11 and the lid 7 by the lid 11 closing the opening of the filter case 20 when not in use, and when used, The cover 11 is installed to be inclined horizontally by the cover 11 which is open from the opening of the filter case 20 and is folded to induce the flow of the residual water.

다음에는, 이와 같이 구성된 본 고안의 작용 및 효과를 설명한다.Next, the operation and effects of the present invention configured as described above will be described.

배수펌핑모터(도시안됨)의 동작에 의한 펌핑력에 의해 배수가 시작되면, 드럼세탁조(12)내의 세탁수(예컨대, 오염수)는 드럼세탁조(12)와 연결된 제1배수호스(2)를 통하여 제4도에 도시한 바와 같이 이물제거수단(10)의 필터케이스(20)내부로 유입됨과 동시에 그 필터케이스(20)내에 삽입장착된 필터부재(5)의 다수개의 구멍(5a)을 통과하여 제2배수호스(3)를 따라 유출되므로써 세탁기본체(1)의 외부로 배수되어 진다.When the drainage is started by the pumping force by the operation of the drain pumping motor (not shown), the washing water (eg, contaminated water) in the drum washing tank 12 is connected to the first drain hose 2 connected to the drum washing tank 12. As shown in FIG. 4, the filter is introduced into the filter case 20 of the foreign material removing means 10 and passes through the plurality of holes 5a of the filter member 5 inserted into the filter case 20. By being discharged along the second drain hose (3) it is drained to the outside of the washing machine body (1).

이때, 상기 필터부재(5)는 그 하부면이 필터케이스(20)와 접촉면적이 적고 그 사이간격이 넓은 구조로 되어 있기 때문에 필터부재(5)에 의해 필터링된 이물질은 충분히 탈수됨과 동시에 이들 접촉면을 통하여 잔수가 고이는 현상을 미연에 방지할 수 있으며, 또한 배수펌핑모터내에 이물질의 유입을 방지할 수 있어 임펠러(도시안됨)의 회전구속현상 및 고장을 미연에 방지할 수 있음은 물론, 배수펌핑모터의 펌핑력을 향상시킬 수 있음과 동시에 수명을 연장시킬 수 있게 된다.At this time, since the lower surface of the filter member 5 has a contact area with the filter case 20 and a wide space therebetween, foreign substances filtered by the filter member 5 are sufficiently dehydrated and at the same time, these contact surfaces. Through this, it is possible to prevent the accumulation of residual water in advance, and also to prevent the inflow of foreign substances into the drain pumping motor, thereby preventing the rotational restraint and failure of the impeller (not shown). The pumping power of the motor can be improved and the life can be extended.

한편, 상기 필터부재(5)에 의해 필터링된 이물질을 세탁기의 외부로 제거하기 위하여 제7도와 같이 덮개(11)의 일측을 누르면, 이 덮개(11)는 힌지핀(부호도시안됨)에 의해 일측으로 회전동작되어 개방됨으로써 필터케이스(20)의 개구에 힌지핀(21)을 매개로 세워 보관된 잔수유도부재(30)가 제6도에 도시한 바와 같이 자체무게 중심에 의해 회전동작됨에 따라 수평을 유지하도록 하여 줌과 동시에 필터케이스(20)내에서 필터부재(5)의 분리동작이 가능한 상태가 되게 하여 준다.Meanwhile, when one side of the cover 11 is pressed to remove the foreign matter filtered by the filter member 5 to the outside of the washing machine, the cover 11 is one side by a hinge pin (not shown). As the residual water inducing member 30 stored upright by the hinge pin 21 in the opening of the filter case 20 is rotated by its own center of gravity as shown in FIG. By keeping it horizontal, the filter member 5 can be detached from the filter case 20 at the same time.

이때, 필터케이스(20)의 단턱(20b)에 록킹결합된 뚜껑(7)을 해제한 후, 필터케이스(20)내에 삽입된 필터부재(5)를 분리시키면, 이 필터부재(5)에 고여있던 잔수 또는 필터케이스(20)의 단턱(20b)에 고여있던 잔수는 상술한 잔수유도부재(30)의 상면을 타고 별도로 비치된 잔수받이그릇(도시안됨)으로 용이하게 유도됨으로써 세탁기주변을 항상 청결하게 유지할 수 있음과 동시에 필터부재(5)에 의해 필터링된 이물질을 용이하게 제거할 수 있는 것이다.At this time, after releasing the lid 7 locked to the step 20b of the filter case 20, the filter member 5 inserted in the filter case 20 is removed, and the filter member 5 is collected. The remaining water or the water remaining on the step 20b of the filter case 20 is easily guided to the remaining water receiving bowl (not shown) on the upper surface of the above-described water induction member 30 so that the surroundings of the washing machine are always It can be kept clean and at the same time can easily remove the foreign matter filtered by the filter member (5).

한편, 이물질제거작업이 끝난 후, 필터케이스(20)내에 필터부재(5)를 삽입시킴과 동시에 뚜껑(7)을 결합시키고, 수평상태의 잔수유도부재(30)를 살짝 들어줌과 동시에 덮개(11)를 닫아주면, 이 잔수유도부재(30)는 덮개(11)의 미는 힘에 의해 수직으로 세워져서 덮개(11)와 뚜껑(7)과의 사이에 형성된 필터케이스(20)의 단턱(20b)에 위치되어 제5도에 도시한 바와 같이 용이하게 보관되는 것이다.On the other hand, after the removal of foreign matters, the filter member 5 is inserted into the filter case 20 and the lid 7 is coupled to each other, and the residual water inducing member 30 in the horizontal state is gently lifted and the cover is closed. (11) is closed, the residual water induction member 30 is vertically erected by the pushing force of the lid 11, the step of the filter case 20 formed between the lid 11 and the lid 7 It is located at 20b and is easily stored as shown in FIG.

이상에서 설명한 바와 같이 본 고안의 드럼세탁기에 의하면, 필터부재의 하부면이 펄터케이스와 접촉면적이 적고 그 사이간격이 넓으며, 또한 필터케이스내에서 필터부재를 분리시켜 이물질을 제거할 때 흘러내리는 잔수를 잔수유도부재에 의해 세탁기본체의 외부로 용이하게 유도할 수 있는 구조로 되어 있기 때문에 이물질제거시 세탁기가 설치된 거실등의 바닥으로 잔수가 흘러내려 매번 걸레로 닦아주는 불편함과 번거로움등을 없앨 수 있는 효과가 있다.As described above, according to the drum washing machine of the present invention, the lower surface of the filter member has a small contact area with the filter case and has a wide space therebetween, and also flows down when the filter member is separated from the filter case to remove foreign substances. It is a structure that can easily guide the remaining water to the outside of the washing machine main body by the remaining water inducing member, so when the foreign matter is removed, the residual water flows to the floor of the living room where the washing machine is installed. There is an effect that can be eliminated.
