본 발명은 세탁기 급수 밸브의 개폐판에 관한 것으로, 특히 배수구를 개폐시켜 주는 개폐판의 급수 배출공에 이물질이 끼어 막히는 것을 방지할 수 있도록 한 세탁기 급수 밸브의 개폐판에 관한 것이다.The present invention relates to an opening and closing plate of a washing machine water supply valve, and more particularly, to an opening and closing plate of a washing machine water supply valve to prevent foreign substances from being blocked in the water supply outlet of the opening and closing plate for opening and closing the drain.

일반적으로 급수 밸브는 제1도에서와 같이 세탁수가 입수되는 입수구(11)와, 상기 입수된 세탁수가 배수되는 배수구(12)로 구비된 몸체부(1)가 구성되고, 상기 몸체부의 배수구(12) 상단에 스프링(23)으로 탄지된 로드(22)가 전자석(21)에 의해 승하강하게 되는 솔레노이드부(2)가 구성되며, 상기 배수구(12) 직상면에는 로드(22)의 승하강에 의해 배수구(12)를 개폐시켜 주는 개폐(3) 즉, 벨로우즈판(31) 중앙과 일측에 미세한 통공(311)과 배수관(312)이 구비되고, 상기 벨로우즈판(31) 저면에 이와 결합된 연질의 벨로우즈(32)가 구비되는데, 상기 벨로우즈(32)의 외주연이 배수구(12)의 상면과 부싱(24)의 하단면 사이에 긴밀히 결합되어 있는 것이다.In general, the water supply valve includes a body portion 1 including an inlet port 11 through which the wash water is received and a drain port 12 through which the wash water is obtained, as shown in FIG. 1, and the drain port 12 of the body part. The solenoid part 2 which the rod 22 supported by the spring 23 on the upper end is raised and lowered by the electromagnet 21, and the upper and lower surfaces of the drain hole 12 are raised and lowered by the rod 22. Opening and closing (3) to open and close the drain port 12, that is, the minute and the minute hole 311 and the drain pipe 312 is provided in the center and one side of the bellows plate, the lower surface of the bellows plate 31 is soft Bellows 32 is provided, the outer periphery of the bellows 32 is tightly coupled between the upper surface of the drain 12 and the lower surface of the bushing (24).

이러한 급수 밸브는 입수구(11)로 세탁수가 입수되며, 이 세탁수는 벨로우즈판(31) 일측에 구비된 통공(311)을 통해 이의 상단으로 유입되어져 있는 상태에서 세탁조내에 세탁수를 급수시켜 주고져 할 경우 솔레노이드부(2)에 전원을 인가하면 즉 전자석(21)에 전원이 인가되면, 상기 전자석(21)의 자력에 의해 스프링(23)으로 탄지되어 벨로우즈판(31) 중앙의 배수관(312)를 밀폐하고 있던 로드(22)가 상승하게 된다. 상기 로드(22)가 상승함에 따라 이에 밀폐되어 있던 배수관(312)이 열려지게 되면, 벨로우즈판(31)의 일측에 구비된 통공(311)을 통해 상부로 유입되어 있던 소량의 세탁수가 중앙의 배수관(312)을 통해 배수구(12)로 배출되게 된다.The water supply valve is supplied with washing water to the inlet 11, the washing water is supplied to the washing water in the washing tank in the state that is introduced to the upper end thereof through the through hole 311 provided on one side of the bellows plate (31) In this case, when power is applied to the solenoid part 2, that is, when power is applied to the electromagnet 21, the drain pipe 312 in the center of the bellows plate 31 is supported by the spring 23 by the magnetic force of the electromagnet 21. The rod 22 which has sealed the seal rises. As the rod 22 rises, when the drain pipe 312 that is closed by the rod 22 is opened, a small amount of washing water introduced into the upper part through the through hole 311 provided at one side of the bellows plate 31 is disposed at the center of the drain pipe. It is discharged to the drain 12 through the 312.

이때 상기 벨로우즈판(31) 상부에 있던 소량의 세탁수가 배수됨에 따라 벨로우즈판(31)의 하부 수압보다 상부 수압이 떨어지게 되므로서, 입수구(11)를 통해 급수되는 세탁수의 수압에 의해 연질의 벨로우즈(32)가 상승하게 되어 벨로우즈(32)와 배수구(12) 상면과의 틈새를 통해 세탁수가 배수구(12)로 배수되게 되는 것이다.At this time, as a small amount of washing water in the upper portion of the bellows plate 31 is drained, the upper water pressure is lower than the lower water pressure of the bellows plate 31, so that the soft bellows is caused by the water pressure of the washing water supplied through the water inlet 11. 32 is to be raised so that the washing water is drained to the drain 12 through the gap between the bellows 32 and the upper surface of the drain 12.

그러나 상기와 같은 급수 밸브에 있어 벨로우즈판(31) 중앙의 배수관(20)과 일측에 통공(311)이 미세하게 구비되어 있으므로서 세탁수에 함유되어 있는 이물질이 상기 미세한 배수관(312)에 끼어 이들을 차단하게 되면 전원이 인가되어 로드(22)가 상승하더라도 개폐부(3)가 배수구(12)를 열어주지 못해 급수가 이루어지지 않게 되며 또한 통공이 폐쇄되면 이를 통한 벨로우즈 상, 하면의 압력 조절이 이루어지지 않으므로 통전하지 않아도 무조건 급수되는 불량이 발생되는 등의 단점이 있었다.However, in the water supply valve as described above, since the through-hole 311 is finely provided at one side of the drain pipe 20 at the center of the bellows plate 31, foreign substances contained in the wash water are inserted into the fine drain pipe 312. If the power is applied and the rod 22 rises, the opening and closing part 3 does not open the drain 12 so that water supply is not performed. Therefore, there was a disadvantage that a poor water supply unconditionally occurs even without power.

즉, 로드(22)가 상승하면 벨로우즈판(31) 상부에 있는 소량의 세탁수가 배수관(312)를 통해 배수되어 수압이 떨어지면 하부의 수압에 의해 벨로우즈(32)가 상승하게 되는데, 배수관(312)내에 이물질이 끼어 이를 차단하게 되면, 로드(22)가 상승하더라도 벨로우즈판(31) 상부의 세탁수가 배수되지 못해 상하부의 수압이 동일하여 벨로우즈(32)가 상승되지 않으므로서 입수구(11)로 유입되는 세탁수가 배수구(12)로 배수되지 못하게 되는 작동불량이 있었다.That is, when the rod 22 is raised, a small amount of washing water in the upper portion of the bellows plate 31 is drained through the drain pipe 312, and when the water pressure drops, the bellows 32 is raised by the water pressure at the lower part. When the foreign matter is stuck in the block 22, even if the rod 22 rises, the washing water in the upper portion of the bellows plate 31 is not drained and the water pressure in the upper and lower portions is the same, so that the bellows 32 does not rise and is introduced into the inlet 11. There was a malfunction in which the wash water could not be drained to the drain 12.

본 발명은 상기와 같은 종래의 제반결함을 감안하여 이루어진 것으로서, 그 목적은 벨로우즈의 배수관내에 이물질이 끼이지 않도록 하여 급수 밸브의 작동 불량을 방지할 수 있도록 한 세탁기 급수 밸브의 개폐판 구조를 제공함에 있다.The present invention has been made in view of the above-mentioned general defects, and an object thereof is to provide an opening and closing plate structure of a washing machine feed valve so that foreign matter is not caught in the bellows drain pipe so as to prevent malfunction of the feed valve. have.

상기 목적을 달성하기 위한 본 발명은 벨로우즈판의 배수관 내부에 구성하여 로드의 승하강에 따라 승하강되어 배수관 내에 끼이는 이물질을 제거할 수 있는 이물질 제거부가 갖추어진 것을 특징으로 하는 것이다.The present invention for achieving the above object is characterized in that the debris is configured to be provided inside the drain pipe of the bellows plate is lowered in accordance with the lifting and lowering of the rod to remove the foreign matter stuck in the drain pipe.

이하 첨부된 도면에 의거하여 본 발명 일실시예의 구성을 설명하면 다음과 같다.Referring to the configuration of an embodiment of the present invention based on the accompanying drawings as follows.

먼저 본 발명 설명의 편이상 종래와 동일한 구성은 동일부호를 기입한다.First, the same reference numerals denote the same components as in the prior art, more than one description of the present invention.

제1도는 일반적인 급수 밸브의 측단면도로서 이의 급수 밸브는 세탁수가 입수되는 입수구(11)와 상기 입수된 세탁수가 배수되는 배수구(12)로 구비된 몸체부(1)가 구성되고, 상기 몸체부의 배수구(12) 상단에 스프링(23)으로 탄지된 로드(22)가 전자석(21)에 의해 승하강하게 되는 솔레노이드부(2)가 구성되며, 상기 배수구(12) 직상면에는 로드(22)의 승하강에 의해 배수구(12)를 개폐시켜 주는 개폐부(3) 즉, 벨로우즈판(31) 중앙과 일측에 미세한 통공(311)과 배수관(312)이 구비되고, 상기 벨로우즈판(31) 저면에 이와 결합된 연질의 벨로우즈(32)가 구비되는데 상기 벨로우즈(32)의 외주연이 배수구(12)의 상면과 부싱(24)의 하단면 사이에 긴밀히 결합되어 있는 것이다.1 is a side cross-sectional view of a general water supply valve, and the water supply valve includes a body portion 1 including an inlet port 11 through which wash water is received and a drain hole 12 through which the wash water is drained. (12) The solenoid portion 2, which the rod 22 supported by the spring 23 on the upper end is raised and lowered by the electromagnet 21, is configured, and the elevating and descending of the rod 22 is disposed on the surface immediately above the drain hole 12. Opening and closing part (3) that opens and closes the drain port 12 by, i.e., a minute through hole 311 and the drain pipe 312 is provided at the center and one side of the bellows plate 31, it is coupled to the bottom of the bellows plate 31 A soft bellows 32 is provided where the outer periphery of the bellows 32 is tightly coupled between the upper surface of the drain 12 and the lower surface of the bushing 24.

이상은 종래와 동일한 구성을 갖는 것이며, 다만 본 발명에서는 제2도와 3도에서와 같이 벨로우즈판(31)의 배수관(312) 내부 하단 소정 위치에 요입홈(313)을 구비하여 이에 끼워져 고정되어 로드(22)의 승하강에 따라 승하강 작동되어 배수관(312) 내에 끼이는 이물질을 제거시켜 주는 이물질 제거부(4)를 구성한 것이다.As described above, the present invention has the same configuration, but in the present invention, as shown in FIG. 2 and FIG. 3, the recessed groove 313 is provided at the lower predetermined position inside the drain pipe 312 of the bellows plate 31 to be inserted into and fixed to the rod. The lifting and lowering operation according to the lifting and lowering of (22) is configured to remove the foreign matter removal unit (4) to remove the foreign matter caught in the drain pipe (312).

상기 이물질 제거부(4)는 배수관(312) 내면에 구비된 요입홈(313)에 요입되도록 동심원상의 탄성철편(41)을 구비하고, 상기 탄성철편(41) 중앙에 이와 일체로 하여 수직으로 구비되어 상기 배수관(312)을 통해 이의 상부로 돌출되는 철핀(42)으로 구비된 것이다.The foreign material removing unit 4 is provided with a concentric elastic iron piece 41 so as to be inserted into the concave groove 313 provided on the inner surface of the drain pipe 312, and vertically provided at the center of the elastic iron piece 41 integrally therewith It is provided with an iron pin 42 protruding to the upper portion through the drain pipe 312.

이러한 구성으로 된 본 발명의 작용 효과를 설명하면 다음과 같다. 먼저 급수 밸브의 작동상태는 종래와 동일한 것이며, 다만 본 발명에서는 솔레노이드부(2)에 전원이 인가되지 않게 되면 스프링(22)의 탄성력에 의해 로드(22)가 하강하여 벨로우즈판(31)의 배수관(312)을 차단하게 되는데, 이때 상기 배수관(312) 상부로 돌출된 철핀(42)이 로드(22)에 의해 배수관(312) 내로 밀려 들어가게 된다.Referring to the operation and effect of the present invention having such a configuration as follows. First, the operation state of the water supply valve is the same as the conventional one, but in the present invention, when power is not applied to the solenoid portion 2, the rod 22 is lowered by the elastic force of the spring 22 to drain the bellows plate 31. 312 is blocked, wherein the iron pin 42 protruding above the drain pipe 312 is pushed into the drain pipe 312 by the rod 22.

이러한 상태에서 세탁조에 세탁수를 급수시키기 위해 전자석(21)에 전원이 인가되면 전자석(21)에 발생된 자력에 의해 스프링(23)으로 탄지된 로드(22)가 상승함에 따라 이에 의해 차단되어 있던 배수관(312)이 열려ㅇ를 통해 세탁수가 배수관(312)을 통해 배수구(12)로 배수됨과 철핀(42)의 눌림에 의해 하부로 강제로 밀린 탄성철편(41)의 복귀력에 의해 이에 수직으로 구비된 철핀(42)이 상승하여 배수관(312) 상부로 상승하게 되므로서, 배수관(312)내로 유입되려는 이물질이 상기 철핀(42)에 의해 유입되지 못하게 되므로서 배수관(312)이 막히지 않게 되는 것이다.In this state, when power is applied to the electromagnet 21 to supply the wash water to the washing tank, the rod 22 supported by the spring 23 is blocked by the magnetic force generated in the electromagnet 21, thereby being blocked. Wash water is drained through the drain pipe 312 through the drain pipe 312 through the drain pipe 312 and vertically by the return force of the elastic iron piece 41 forcibly pushed downward by the pressing of the iron pin 42. Since the iron pin 42 is provided to rise to the upper portion of the drain pipe 312, the foreign material to be introduced into the drain pipe 312 is prevented from being introduced by the iron pin 42 so that the drain pipe 312 is not blocked. .

따라서 본 발명은 로드의 승하강에 따라 배수관 내에 구비된 철핀이 상하작동되므로서 배수관내에 세탁수에 함유되어 있는 이물질이 유입되지 못하게 되어 있어 이물질에 의해 배수관에 막히는 일이 없으며, 배수관의 막힘에 의한 개폐부의 작동불량이 발생하지 않게 되는 등의 효과가 있는 것이다.Therefore, according to the present invention, since the iron pin provided in the drain pipe is operated up and down as the rod is raised and lowered, foreign matters contained in the wash water are not introduced into the drain pipe, so that the foreign matter is not blocked by the foreign material and is blocked by the drain pipe. There is an effect such that the malfunction of the switch unit does not occur.
