본 발명은 세탁기에 관한 것으로, 상세하게는 세탁기의 오버플로우 유로 내부에 나노 실버가 함유된 수평 돌출부를 반복 형성하여 상기한 수평 돌출부의 항균력에 의해 오버플로우된 세탁수중의 미생물을 소멸시키고, 오버플로우 유로로부터미생물의 번식을 차단하는 한편, 이에 따라 악취의 발생과 세탁물이 유해 미생물에 의해 오염되는 것을 차단하도록 구성한 것이다.The present invention relates to a washing machine, and in detail, the horizontal protrusions containing nano silver are repeatedly formed in the overflow flow path of the washing machine to dissipate microorganisms in the washing water overflowed by the antibacterial activity of the horizontal protrusions, and overflow While preventing the growth of microorganisms from the flow path, it is configured to block the generation of odor and contaminated laundry by harmful microorganisms.

일반적으로 세탁조가 지면으로부터 수직으로 회전하는 한편, 세탁조 내부의 펄세이터가 회전하는 과정에서 발생한 수류의 형성에 의해 세탁이 이루어지는 펄세이터 방식의 세탁기는 도 1과 같이 세탁공간을 제공하는 세탁조(150)의 외부에 저수조(160)가 결합된다.In general, the washing tank is rotated vertically from the ground, while the washing machine of the pulsator type washing is formed by the formation of water flow generated in the process of rotating the pulsator inside the washing tank is a washing tank 150 to provide a laundry space as shown in FIG. The reservoir 160 is coupled to the outside of the.

또한, 상기한 저수조(160)의 외주면 일측에는 저수조(160)의 만수위 상부와 연통되는 오버플로우 유로(145)가 형성되며, 세탁조(150)의 저부에는 기어 어셈블리(180)를 경유하여 전달된 모터(170)의 회전력에 의해 회전함으로써 세탁수에 수류를 형성시키는 펄세이터(110)가 결합된다.In addition, an overflow passage 145 is formed at one side of the outer circumferential surface of the water storage tank 160 to communicate with the water level upper portion of the water storage tank 160, and a motor transmitted through the gear assembly 180 at the bottom of the washing tank 150. By rotating by the rotational force of 170 is coupled to the pulsator 110 to form a water flow in the wash water.

상기한 펄세이터(110)는 통상적으로 원반형상으로 이루어진 몸체의 상부에 날개차를 방사상으로 돌출시킨 구조로 이루어진 것으로, 정역회전과정에서 형성된 수류와 함께 세탁수의 일부가 오버플로우 유로(145)를 경유하여 세탁조(150)로 토출되는 과정에서 발생한 낙차에너지에 의해 세탁이 이루어지도록 한다.The pulsator 110 has a structure in which a vane radially protrudes on an upper portion of a body having a disk shape, and a part of the wash water flows through the overflow passage 145 together with the water flow formed during the forward and reverse rotation. Washing is performed by free fall energy generated in the process of being discharged to the washing tank 150 via.

이때 상기한 바와 같이 세탁수가 토출되는 오버플로우 유로(145)의 일측으로는 필터(F)가 결합됨으로써 세탁조(150)로 토출되는 세탁수로부터 보풀이나 세탁물에 부착된 오물과 같은 이물질 등을 제거한다.At this time, the filter (F) is coupled to one side of the overflow passage 145 through which the washing water is discharged, thereby removing foreign substances such as lint and dirt attached to the laundry from the washing water discharged to the washing tank 150. .

상기한 바와 같은 세탁기용 필터(F)는 통상적으로 오버플로우 유로(145)로부터 탈착가능하게 결합되는 프레임의 내측에 망체형상의 포집망을 부착시킨 구조로 이루어짐으로써 오버플로우 유로(145)의 내측에 결합된 상태에서 오버플로우유로(145)를 통해 유입된 세탁수로부터 이물질을 포집망에 의해 제거하는 한편, 세탁수를 세탁조(150)로 재순환시킨다.Washing machine filter (F) as described above is made of a structure in which a mesh-shaped trapping net is attached to the inner side of the frame detachably coupled from the overflow flow path 145 to the inside of the overflow flow path (145). In the combined state, foreign substances are removed from the wash water introduced through the overflow passage 145 by the trap network, and the wash water is recycled to the washing tank 150.

한편, 상기한 오버플로우 유로(145)는 세탁과정에서 오물을 포함한 이물질의 통과경로를 제공함으로써 오염물질에 노출된 구조를 갖게 되는데, 통상적인 세탁기는 오버플로우 유로(145)가 커버(145A)에 의해 밀폐됨으로써 세탁기의 장시간 사용시 오버플로우 유로(145)가 이물질에 의해 쉽게 오염된다.On the other hand, the overflow flow path 145 has a structure exposed to contaminants by providing a passage path of foreign matter including dirt in the washing process, the conventional washing machine has an overflow flow path 145 is a cover 145A By being sealed by the overflow flow path 145 is easily contaminated by foreign matter during long time use of the washing machine.

특히, 오버플로우 유로(145)의 벽면에 정착된 섬유 유연제나 세제가 중성의 수소이온농도(pH) 값을 갖는 관계로 바이러스나 박테리아, 곰팡이와 같은 미생물에 대해 유용한 증식환경을 제공하므로 장시간 사용시 악취가 발생하거나 세탁과정에서 인체에 유해한 미생물이 세탁조(150)로 재유입되는 등의 문제점이 발생한다.In particular, since the fabric softener or detergent settled on the wall of the overflow passage 145 has a neutral pH value, it provides a useful proliferation environment for microorganisms such as viruses, bacteria, and fungi, thus causing odor during prolonged use. Occurs or problems such as microorganisms harmful to the human body is re-introduced into the washing tank 150 in the washing process.
