본 고안은 배수호스를 통해 식기세척기 외부로 배출된 오수(汚水)가 식기세척기 내부로 역류하는 것을 방지할 수 있도록 하는 식기세척기의 오수 역류방지장치에 관한 것이다.The present invention relates to a sewage backflow prevention device of the dishwasher to prevent the backwater discharged to the outside of the dishwasher through the drain hose.

일반적으로 식기세척기의 배수는 식기세척기 내하부에 집수된 물을 안내하는 배수관에 설치되는 배수펌프에 의해 행해진다.In general, the drainage of the dishwasher is performed by a drain pump installed in a drain pipe for guiding the water collected in the lower part of the dishwasher.

즉, 제3도와 같이 식기세척기(1') 내하부에는 배수관(10')이 설치되고 배수관(10')의 유출측에는 배수펌프(20')와 배수호스(50')가 설치되어 배수펌프(20')가 가동되면 배수관(10')의 물이 배수호스(50')를 통해 외부로 배출되도록 구성되어 있는 예가 많다.That is, as shown in FIG. 3, the drainage pipe 10 'is installed in the lower part of the dishwasher 1', and the drainage pump 20 'and the drainage hose 50' are installed on the outlet side of the drainage pipe 10 '. When the 20 'is operated, there are many examples in which the water in the drain pipe 10' is configured to be discharged to the outside through the drain hose 50 '.

그런데 종래에는 배수가 완료되고 배수펌프(20')가 정지한 후에 배수관(10')의 압력이 배수호스(50')의 압력보다 낮은 경우에 배수호스(50')내의 오수(汚水)가 배수펌프(20')를 경유하여 배수관(10')으로 역류되고 식기세척기(1') 내부까지 진입하게 되어 세척을 마친 식기들이 재차 오염되는 문제가 있었다.However, conventionally, after the drainage is completed and the drainage pump 20 'stops, the sewage in the drainage hose 50' is drained when the pressure in the drainage pipe 10 'is lower than the pressure of the drainage hose 50'. Through the pump 20 ', the water was returned to the drain pipe 10' and entered into the dish washer 1 '.

또한, 일본국 공개 실용신안공보 소 53-15660호와 같이 세척수량에 따라 상, 하로 승강하는 자석이 내장된 플로트(5)와 자력을 감지할 수 있는 스위치(6)에 의하여 물량을 조절할 수 있는 수위 제어장치가 있으며 이는 볼(7)이 식기세척기내로 물이 유입될 때 급속한 수압에 의해 플로트(5)가 영향을 받아 스위치(6)가 오류를 범하는 것을 예방하기 위한 것으로 이는 세척을 위한 급수량을 조절하는 것으로 배수시에 잔재하는 오수의 역류를 방지할 수 없어 세척상태가 불량하게 되었던 것이다.In addition, as shown in Japanese Utility Model Publication No. 53-15660, the quantity can be adjusted by a float (5) with a built-in magnet that moves up and down according to the amount of washing, and a switch (6) capable of sensing magnetic force. There is a water level control device to prevent the float 6 from being affected by the rapid water pressure when the ball 7 is introduced into the dishwasher, thereby preventing the switch 6 from making an error. By controlling this, the backflow of the sewage remaining during the drainage could not be prevented, so the cleaning state was poor.

이와 같은 경우에는 애써 세척한 식기들을 재차 세척해야 하는 번거로움을 겪게 됨은 물론 세척수와 세재를 낭비하는 결과를 초래하게 된다.In such a case, the dishwashed dishes have to be washed again, resulting in waste of washing water and detergent.

본 고안은 상기 종래의 실정을 감안하여 안출한 것이며, 그 목적은 배수호스로부터의 오수가 역류되는 것을 차단하여 세척을 마친 식기들이 재차 오염되는 것을 방지할 수 있도록 하는 식기세척기의 오수 역류방지장치를 제공하는데 있다.The present invention has been made in view of the above-mentioned conventional situation, and its object is to prevent the backflow of wastewater from the drain hose to prevent backwashing of the dishwasher to prevent contamination of the finished dishes again. To provide.

본 고안은 상기의 목적을 달성하기 위하여 배수펌프의 유출측과 배수호스의 유입측사이에 유체의 흐름을 일방향으로만 진행시키는 체크밸브를 설치하는 것을 특징으로 하며, 이하 그 구체적인 내용을 첨부도면에 도시한 한 실시예를 통하여 더욱 상세히 설명하면 다음과 같다.The present invention is characterized in that to install a check valve for advancing the flow of fluid in only one direction between the outlet side of the drain pump and the inlet side of the drain hose in order to achieve the above object, the specific content of the When described in more detail through an embodiment shown as follows.

즉, 본 고안은 제2도와 같이 안내되는 배수관(10)에 배수펌프(20)와 배수펌프(20)와 배수호스(50) 사이에 유체의 흐름을 한쪽으로만 진행시키는 체크밸브(40)를 설치하여서 되는 것이다.That is, the present invention has a check valve 40 for advancing the flow of fluid between the drain pump 20 and the drain pump 20 and the drain hose 50 to the drain pipe 10 guided as shown in FIG. By installation.

상기에서 체크밸브(40)는 제1도와 같이 양단이 개구된 상협하광(上狹下廣)의 원통형의 밸브몸체(41)와 그에 내장되는 볼형밸브(42), 받침판(43)으로 이루어진다.In the above, the check valve 40 is composed of a cylindrical valve body 41 of upper and lower light having both ends opened as shown in FIG. 1, a ball valve 42, and a support plate 43 embedded therein.

상기 체크밸브(40)의 밸브몸체(41)의 상단에는 결합관(41a)이 형성되어 배수펌프(20)의 유출측에 연결된 연결관(30)의 후단이 결합되고, 하단에는 받침플랜지(51)가 형성된 배수호스(50)의 선단부가 결합된다.A coupling pipe 41a is formed at the upper end of the valve body 41 of the check valve 40 so that the rear end of the connecting pipe 30 connected to the outlet side of the drainage pump 20 is coupled, and the support flange 51 at the lower end thereof. The tip of the drain hose 50 is formed.

또한, 받침판(43)은 밸브몸체(41)의 내하부에 형성된 걸림턱(41b)의 하단에 설치되고 밸브몸체(41)의 내하부로 진입하는 배수호스(50) 선단으로 받쳐진다.In addition, the support plate 43 is installed at the lower end of the locking jaw 41b formed in the lower portion of the valve body 41 and is supported by the tip of the drain hose 50 entering the inner lower portion of the valve body 41.

상기 받침판(43)은 그 상단중앙에 볼형 밸브(42)를 받쳐주는 돌출환테(43a)가 형성되고 돌출환테(43a)의 둘레에 다수의 통수공(43b)이 형성된 형태를 갖는다.The supporting plate 43 has a shape in which a protruding annulus 43a supporting the ball valve 42 is formed at the center of the upper end thereof, and a plurality of water passages 43b are formed around the protruding annulus 43a.

상기와 같은 본 고안은 식기세척기(1) 내하부에 집수된 물이 배수관(10)에 안내되어 배수호스(50)로 배출되는 과정에서는 원활한 배수동작에 이루어지게 되고 그 반대로 배수호스(50)로부터 배수관(10)쪽으로 역류하는 물은 체크밸브(40)에 의해 차단되도록 구성된 것인 바, 그 구체적인 동작을 설명하면 다음과 같다.The present invention as described above is made in a smooth drainage operation in the process of the water collected in the lower part of the dishwasher 1 is guided to the drain pipe 10 and discharged to the drain hose 50 and vice versa from the drain hose 50 Water flowing back toward the drain pipe 10 is configured to be blocked by the check valve 40, the specific operation of which will be described below.

즉, 배수펌프(20)에 의해 배수관(10)의 물이 연결관(30)을 경유하여 체크밸브(40)로 진입할 때는 볼형 밸브(42)가 자중에 의해 받침판(43)의 돌출환테(43a)에 올려진 상태를 유지하게 되므로 받침판(43)의 통수공(43b)을 통해 배수호스(50)로 오수를 배출시킬 수 있게 되고, 만약 배수관(10)쪽의 압력이 배수호스(50)쪽보다 낮아 배수호스(50)내의 오수가 역류할 때는 역류하는 물이 볼형 밸브(42)를 상부로 밀어올리게 되므로 제1도의 가상선 상태와 같이 밸브몸체 상부의 결합관(41a)이 밀폐되어 역류되는 오수가 연결관(30) 및 배수펌프(20)로 진입할 수 없게 되는 것이다.That is, when the water in the drain pipe 10 enters the check valve 40 through the connecting pipe 30 by the drain pump 20, the ball-type valve 42 protrudes from the support plate 43 by its own weight. 43a) to maintain the raised state can be discharged to the drainage hose 50 through the water supply hole (43b) of the support plate 43, if the pressure on the drain pipe 10 side drain hose (50) When the sewage in the drain hose 50 flows backward, the water flowing back pushes the ball valve 42 upward, so that the coupling pipe 41a in the upper portion of the valve body is sealed and flowed back as shown in FIG. The sewage is to be able to enter the connection pipe 30 and the drainage pump 20.

이상에서와 같이 본 고안은 일단 배수호스(50)로 배출된 오수가 재차 식기세척기(1) 내부로 진입할 수 없게 함으로써 세척을 마친 식기들이 다시 오염되는 일이 없게 할 수 있게되어 더욱 안심하고 식기세척기(1)를 사용할 수 있게 하는 신규유용의 실용적인 고안인 것이다.As described above, the present invention prevents the wastewater discharged into the drain hose 50 from entering the dishwasher 1 again, so that the dishes that have been washed can not be contaminated again. It is a practical design for the new useful to be able to use the washing machine (1).
