As shown in the drawing, a conventional vertical washing machine rotates inside a housing 1 forming an exterior, a cylindrical water tank 2 vertically installed inside the housing 1 to accommodate washing water, and a water tank 2. Cylindrical dehydration tank (3) having a plurality of dehydration holes (3a) formed on the outer circumferential surface, the pulsator (4), the water tank (2) installed in the inner lower part of the dehydration tank (3) to generate the water flow A drive motor 5 and a power transmission device 6 are installed at an outer lower part to rotate the pulsator 4 and the dehydration tank 3.

하우징(1)의 상부는 탈수조(3)로 세탁물을 넣거나 꺼낼 수 있도록 개방되어 있으며, 이 개방된 하우징(1)의 상부에는 탈수조(3)를 개방 또는 폐쇄하기 위한 도어(7)가 힌지 결합되어 있다. 또한, 수조(2)의 하부에는 세탁이 완료되어 수조(2)에 담겨진 세탁수를 외부로 배출하기 위해 하우징(1)의 외부로 연장되는배수호스(8)가 설치되어 있다.The upper part of the housing 1 is open to put or take out laundry into the dehydrating tank 3, and the upper part of the open housing 1 is hinged by a door 7 for opening or closing the dehydrating tank 3. Are combined. In addition, the lower portion of the water tank 2 is provided with a drainage hose 8 extending to the outside of the housing 1 in order to discharge the washing water contained in the water tank 2 to the outside.

탈수조(3)의 내벽면에는 세탁행정시 펄세이터(4)의 정역 회전에 의해 발생하는 수류를 탈수조(3)의 상부로 유도하여 세탁수에 포함된 보푸라기 등과 같은 이물질을 걸러내기 위한 이물질 걸름장치(10)가 부착되어 있다.On the inner wall surface of the dehydration tank (3), foreign matter for filtering foreign matters such as lint or the like contained in the wash water by inducing water flow generated by the forward and reverse rotation of the pulsator (4) during washing administration to the upper part of the dehydration tank (3). The strainer 10 is attached.

상기 이물질 걸름장치(10)에는 펄세이터(4)에 의해 발생되는 상승수류에 포함된 보푸라기나 세탁물 찌꺼기와 같은 이물질을 걸러내기 위해 다수의 미세한 직경의 홀이 형성된 찌꺼기 걸름망(11)이 설치되어 있다.The debris filtering device 10 is provided with a debris filtering net 11 having a plurality of fine diameter holes formed to filter foreign matters such as lint or laundry debris contained in the upward stream generated by the pulsator 4. .

상기와 같이 구성된 종래의 이물질 걸름장치(10)를 구비한 수직축 세탁기에 있어서, 탈수조(3)에 세탁물을 투입한 후에 세탁기를 작동시키게 되면, 수조(2)에 물이 공급되고 나서 구동모터(5)와 동력전달장치(6)에 의해 펄세이터(4)가 정역회전하게 된다. 이러한 펄세이터(4)의 회전에 의해 세탁수류가 발생되어 세탁물이 세탁수류와 함께 유동하게 되고, 또한 탈수조(3)와 마찰됨으로써 세탁이 되는 것이다. 이 때, 펄세이터(4)에 의해 발생된 세탁수류의 일부는 이물질 걸름장치(10)를 통해 탈수조(3)의 상부로 상승된 후, 이물질 걸름장치(10)의 찌꺼기 걸름망(11)을 통과하게 되면서 세탁수에 포함된 보푸라기 등은 찌꺼기 걸름망(11)에 의해 걸러지게 되고, 찌꺼기 걸름망(11)을 통과한 세탁수는 다시 탈수조(3)로 보내지게 되는 것이다.In the vertical washing machine equipped with a conventional foreign matter trapping device 10 configured as described above, when the washing machine is operated after the laundry is put into the dehydration tank (3), the driving motor after supplying water to the tank (2) 5) and the power transmission device 6 causes the pulsator 4 to rotate forward and backward. The rotation of the pulsator 4 causes the washing water flow so that the laundry flows together with the washing water flow, and the washing is performed by friction with the dehydration tank 3. At this time, a part of the washing water generated by the pulsator (4) is raised to the upper portion of the dehydration tank (3) through the foreign matter filtering device 10, and then the debris filter net of the foreign material filtering device (10) The lint or the like contained in the wash water is filtered by the scum filter net 11, and the wash water passing through the scum filter net 11 is sent back to the dehydration tank (3).

일정시간이 경과하여 세탁과정이 완료되면 배수호스(8)를 통하여 세탁수를 배수시킨 다음 세탁물로부터 세제액을 빼내는 헹굼과정을 거치게 된다. 그 후에 구동모터(5)와 동력전달장치(6)에 의해 다시 탈수조(3)를 고속으로 회전시켜서 세탁물을 탈수시킴으로써 세탁물의 세탁이 완료되는 것이다.After a certain period of time, when the washing process is completed, the washing water is drained through the drain hose 8 and then rinsed to remove the detergent solution from the laundry. After that, the drive motor 5 and the power transmission device 6 rotate the dewatering tank 3 again at high speed to dehydrate the laundry, thereby completing the washing of the laundry.

그러나 종래의 이물질 걸름장치(10)에 있어서, 이물질을 걸러내기 위한 찌꺼기 걸름망(11)은 일반적으로 스테인레스 스틸 재질 또는 플라스틱 재질로 만들어지기 때문에, 이 찌꺼기 걸름망(11)에 걸려진 세탁물 찌꺼기로부터 유해세균이 발생되는 단점이 있다.However, in the conventional foreign matter strainer 10, since the waste strainer 11 for filtering the foreign substance is generally made of stainless steel or plastic material, harmful bacteria from the laundry waste caught by the waste strainer 11 This has the disadvantage of being generated.

즉, 세탁행정시 펄세이터(4)에 의해 이물질 걸름장치(10)로 유입된 세탁수는 찌꺼기 걸름망(11)을 통과하여 다시 탈수조(3)로 보내지고, 세탁수에 포함된 세탁물 찌꺼기는 찌꺼기 걸름망(11)에 걸려져서 모아지게 되는데, 일정기간 지나게 되면 많은 양의 찌꺼기가 쌓이게 되고, 이 쌓여진 찌꺼기로부터 유해세균이나 미생물이 생성하게 되는 것이다. 특히, 물과 세제를 사용하는 세탁기의 기능상 세탁기의 내부에는 습기에 의해 미생물이 번식하기 쉬운 환경이 제공되기 때문에, 종래의 이물질 걸름장치(10)를 구비한 세탁기는 미생물의 생성과 번식을 용이하게 유발시키게 되는 것이다.That is, the washing water introduced into the foreign substance filtering device 10 by the pulsator 4 during the washing administration is sent to the dehydration tank 3 again through the waste strainer 11, and the laundry waste contained in the washing water is It will be collected by hanging on the filter strainer 11, after a certain period of time, a large amount of residue is accumulated, and harmful bacteria or microorganisms are produced from the accumulated residue. In particular, since the environment of the washing machine using water and detergent provides an environment where microorganisms are easily propagated by moisture, the washing machine having the conventional foreign matter trapping device 10 facilitates the production and reproduction of microorganisms. It is triggered.

따라서 종래의 세탁기에 의해 세탁된 세탁물에는 피부에 좋지 않은 유해세균이 다량 부착됨으로써 피부 알러지 등을 유발하게 되는 등 위생에 좋지 않게 되며, 이에 따라 사용자에게 불쾌감을 주고 건강을 해치게 되는 원인이 되는 것이다.Therefore, the laundry washed by the conventional washing machine is attached to a large amount of harmful bacteria that are not good for the skin, causing allergies, such as skin allergy, which is not good for hygiene, thereby causing discomfort to the user and harm to health.

본 발명은 상술한 종래기술의 문제점을 해결하기 위한 것으로, 본 발명의 목적은 이물질 걸름장치에 살균기능을 부여하여 세탁물 찌꺼기로부터 유해세균의 생성을 방지하도록 한 세탁기를 제공하는 것이다.The present invention is to solve the above-mentioned problems of the prior art, an object of the present invention is to provide a washing machine to prevent the generation of harmful bacteria from the laundry waste by providing a sterilization function to the foreign matter filtering device.
