본 고안은 세탁기의 세탁수 역류방지장치에 관한 것으로, 특히, 세탁물의 세탁에 의해 오염된 세탁수가 저수조로 역류하는 것을 차단시켜 주어 세탁물의 세탁력을 향상시켜 줄수 있도록 한 세탁기의 세탁수 역류방지장치에 관한 것이다.The present invention relates to a wash water backflow prevention device of a washing machine, and more particularly, to a wash water backflow prevention device of a washing machine, which prevents the wash water contaminated by washing of the laundry to flow back into the water tank to improve the washing power of the laundry. It is about.

일반적으로 세탁수의 배수장치는 배수호오스가 저수조의 하부에 위치하도록 하여 배수밸브가 열리면 세탁수가 흘러내려 배수될수 있도록 하는 자연배수방식과 배수펌프에 의해 강제로 세탁수를 배수시켜 주는 강제배수방식으로 나뉘어져 있는데, 강제배수방식 즉, 배수펌프에 의해 강제로 배수되는 배수방식은 주로 유럽에서 사용되는 것으로서, 세탁기를 주방이나 거실에 설치한 상태에서 배수호오스를 씽크대에 걸어주고 세탁물의 세탁이나 헹굼이 완료되면 배수펌프를 가동시켜 이에 의해 세탁수가 강제로 배수될수 있도록 하고있는 것이다.In general, the drainage system of the wash water is a natural drainage method in which the drain hose is located at the bottom of the water reservoir so that the wash water flows down when the drain valve is opened and a forced drainage method for forcibly draining the wash water by the drainage pump. Forced drainage method, that is, drainage method that is forcibly drained by the drainage pump, is mainly used in Europe. The drainage hose is placed on the sink with the washing machine installed in the kitchen or living room, and washing or rinsing of the laundry is completed. When the drain pump is operated to allow the wash water to be forcibly drained.

이러한 배수장치는 배수펌프에 의해 강제로 배수되더라도 세탁수가 완전히 배수되지 않고 소정량의 세탁수가 배수호오스와 배수펌프내에 잔류하고 있다가 세탁수를 배수시켜 주고져 배수펌프를 가동하면 잔류하고 있던 오염된 세탁수가 배수관을 통해 저수조내로 역류를 함으로써, 상기 역류되는 세탁수에 의해 세탁된 깨끗한 세탁물이 더럽혀지게 되는 단점이 있었으며, 이로인해 세탁성능이 저하되게 되는 단점이 있고, 상기 더럽혀진 세탁물을 재차 세탁하여 주어야 함으로써, 세탁수의 낭비를 초래하였던 문제점이 있었던 것이다.Even if the drainage system is forcibly drained by the drainage pump, the wash water is not completely drained, but a certain amount of wash water remains in the drainage hose and the drainage pump, and the washwater is drained. By washing the water back to the reservoir through the drain pipe, there was a disadvantage that the clean laundry washed by the backwashing water is dirty, there is a disadvantage that the washing performance is deteriorated, and the dirty laundry has to be washed again By doing so, there was a problem that caused waste of washing water.

따라서, 본 고안의 목적은 세탁수를 배수시에는 배수되는 세탁수의 수압에 의해 하향되면서 배수관을 열어주게 되어 세탁수가 원활히 배수되고, 배수호오스와 배수펌프에 잔류하고 있는 세탁수가 역류시에는 이의 수압에 의해 부상되면서 배수관을 긴밀히 차단시켜 주어 오염된 세탁수의 역류를 방지하여 세탁물의 세탁성능을 향상시켜 줄수 있도록 하는 세탁기의 세탁수 역류방지장치를 제공함에 있다.Therefore, an object of the present invention is to open the drainage pipe while being lowered by the water pressure of the wash water drained when the water is drained, and the wash water is smoothly drained, and the water pressure in the wash water remaining in the drain hose and the drain pump is reversed. It is to provide a washing water backflow prevention device of the washing machine to be able to improve the washing performance of the laundry by preventing the backflow of contaminated wash water by closely blocking the drain pipe while being injured by.

이러한 목적을 달성하기 위한 본 고안은 저수조의 하단부에 연결된 상태에서 배수펌프에 의해 세탁수가 배수될수 있도록 하는 배수관에 있어서, 상기 배수관의 내부에 세탁수가 배수시에는 배수관을 열어주고 세탁수가 역류시 세탁수의 부력에 의해 부상되어 배수관을 긴밀히 차단시켜 줌으로써, 세탁수의 역류를 차단시켜 줄수 있도록 하는 역류방지수단을 갖춘 것을 특징으로 하는 것이다.The present invention for achieving the above object is a drain pipe for washing water can be drained by a drain pump in a state connected to the lower end of the reservoir, when the wash water is drained inside the drain pipe to open the drain pipe and the wash water backwash It is characterized by having a backflow prevention means that can be blocked by the buoyancy of the water tightly blocking the drain pipe, to block the backflow of the wash water.

이하, 첨부된 도면에 의거하여 본 고안 일실시예의 구성을 설명하면 다음과 같다.Hereinafter, the configuration of an embodiment of the present invention based on the accompanying drawings.

제1도는 본 고안이 적용된 상태를 보인 세탁기의 측단면도이고, 제2도는 본 고안의 구성을 보인 요부확대 단면도로서, 외체(100)의 내부에 세탁수를 담수하여 주는 저수조(200)와, 상기 저수조의 내부에 세탁물을 담아주는 세탁조(300)와, 세탁조의 내부 하단에 세탁수의 회전수류를 일으켜 주는 회전익(400)과, 저수조의 저면에 세탁조 및 회전익을 회전시켜 주는 구동부(500)와, 저수조의 저면 일측에 배수펌프(600)에 의해 세탁수를 배수시켜 주는 배수관(700)으로 구성된 세탁기에 있어서, 상기 배수관의 내부에 세탁수가 배수시에는 배수관을 열어주고 세탁수가 역류시 세탁수의 부력에 의해 부상되어 배수관을 긴밀히 차단시켜 줌으로써, 세탁수의 역류를 차단시켜 줄수 있도록 하는 역류방지수단(800)을 갖추어 진다.1 is a side cross-sectional view of a washing machine showing a state of the present invention, Figure 2 is an enlarged cross-sectional view of the main portion showing the configuration of the present invention, the reservoir 200 for fresh water to wash the inside of the outer body 100, and Washing tank 300 for storing the laundry inside the reservoir, a rotary blade 400 for causing the water flow in the lower portion of the washing tank, the drive unit 500 for rotating the washing tank and the rotary blade on the bottom of the reservoir, In the washing machine consisting of a drain pipe 700 for draining the wash water by the drain pump 600 on one side of the bottom of the reservoir, the washing water in the drain pipe opens the drain pipe when the drainage and the wash water buoyancy of the wash water backflow It is equipped with a backflow prevention means (800) for blocking the back flow of the washing water by being blocked by the tightly blocked by the drain pipe.

상기의 역류방지수단(800)은 세탁수가 배수되는 배수관(700)의 적당한 위치에 이보다 다소의 크기를 갖는 상태에서 유선형으로 절곡된 수용부(810)와, 상기 수용부의 내부에 역류되는 세탁수에 의해 부상되어 배수관을 밀폐시켜 주는 원형의 밀폐부(820)와, 상기 수용부의 바닥면에 하향되는 밀폐부가 배수관의 하부를 밀폐시켜 주지 못하도록 하는 걸림턱(830)으로 구성되는 것이다.The backflow preventing means 800 is a receiving portion 810 bent in a streamlined shape in a state having a size slightly more than this in a suitable position of the drain pipe 700 for draining the wash water, and the wash water flowed back inside the receiving portion It is composed of a circular sealing portion 820, which floats to seal the drain pipe, and a locking jaw 830 that prevents the sealing portion which is downward from the bottom surface of the receiving portion from sealing the lower portion of the drain pipe.

이때, 상기의 밀폐부는 세탁수의 수압에 의해 부상되지는 않도록 하고, 역류되는 세탁수의 수압에 의해서는 상승을 할수 있도록 하여 되는 것이다.At this time, the sealing part is to be prevented from being floated by the water pressure of the washing water, and to be able to rise by the water pressure of the washing water backflow.

상기와 같은 구성으로 하는 본 고안은 저수조내에 세탁수가 없거나 세탁수가 담수되어 있는 상태에서는 밀폐부가 자체의 하중에 의해 수용부(810)의 하부로 떨어져 내측으로 돌출되어 있는 걸림턱(830)에 걸려 안치됨에 따라 배수관을 완전히 차단시켜 주지 않게되어 세탁수의 배수에는 아무런 장애를 받지않게 된다.According to the present invention having the above configuration, when the wash water or the wash water is in the water tank, the sealing part is caught and caught by the locking jaw 830 that protrudes inward to the lower part of the receiving part 810 by its own load. As a result, the drain pipe is not completely blocked, so that the drainage of the wash water does not have any obstacle.

이러한 상태에서 세탁물의 세탁행정이 완료되면 배수펌프(600)의 가동에 의해 저수조에 담수되어 세탁물을 세탁한 오염된 세탁수가 배수펌프에 의해 강제배수가 이루어지게 된다.In this state, when the washing administration of the laundry is completed, the contaminated washing water that is freshly washed in the water tank by washing the laundry by the operation of the drain pump 600 is forcedly drained by the drain pump.

상기와 같은 상태로 하여 세탁수의 배수가 완료되면 배수펌프의 가동이 중단되게 되는데, 이때 배수펌프와 배수호오스 사이에 세탁물을 세탁하면서 더러워진 세탁수가 완전히 배수되지 않고 소정량이 잔류를 하게 된다.When the drainage of the wash water is completed in the above state, the operation of the drain pump is stopped. At this time, while washing the laundry between the drain pump and the drain hose, the dirty laundry water is not completely drained and a predetermined amount remains.

그러한 상태에서 상기 배수호오스나 배수펌프에 잔류하고 있는 세탁수가 역류를 하게되면 역류되는 세탁수에 의해 걸림턱(830)에 걸려져 있던 밀폐부(820)가 부상되어 열려져 있던 배수관을 긴밀히 차단시켜 주므로서 저수조내로 역류되지 못하도록 하므로서, 역류되는 세탁수에 의해 세탁이 완료된 세탁물이 더럽혀지지 않게 되는 것이다.In such a state, when the wash water remaining in the drain hose or the drain pump flows back, the sealing part 820, which is caught on the locking jaw 830, is injured by the wash water flowing back to close the open drain pipe. By preventing the backflow into the reservoir, the laundry that has been washed is not polluted by the backwashing water.

따라서, 본 고안은 배수펌프나 배수호오스에 잔류하고 있던 세탁수가 역류시 배수관의 적당한 위치에 구성된 역류방지수단의 밀폐부가 역류되는 세탁수의 수압에 의해 부상되어 배수관을 긴밀히 밀폐시켜 줌에따라 세탁이 되면서 오염된 세탁수가 저수조내로 역류를 하지 못하게 됨으로써, 세탁이 완료된 세탁물이 역류되는 세탁수에 의해 더럽혀지지 않게 되어 세탁물의 세탁력을 높여주게 됨은 물론, 이로인해 세탁물을 재차 세탁하여 주어야 하는 번거로움이 없게 되는 등의 효과가 있는 것이다.Therefore, the present invention is the washing water remaining in the drainage pump or drainage hose when the backflow of the backflow prevention means configured at the proper position of the drainage pipe when the backflow is injured by the water pressure of the backwashing water to close the drain pipe tightly closed As the contaminated wash water does not flow back into the water reservoir, the washed laundry is not polluted by the backwash water, thereby increasing the washing power of the laundry, and thus, the hassle of having to wash the laundry again. It will be effective.
