본 발명은 냉장고용 물 공급장치에 관한 것으로서, 더욱 상세하게는 냉장실 도어에 설치된 물 공급장치의 급수동작을 솔레노이드를 이용하여 제어하여 부품수와 작동구조를 단순화하고 누수 및 잔수율을 감소시켜 물 공급효율을 향상시킬 수 있게 한 냉장고용 물 공급장치에 관한 것이다.The present invention relates to a water supply device for a refrigerator, and more particularly, a water supply operation of a water supply device installed in a refrigerating compartment door is controlled by using a solenoid, thereby simplifying the number of parts and operation structure and reducing water leakage and residual water supply. The present invention relates to a refrigerator water supply device capable of improving efficiency.
일반적으로, 냉장고용 물 공급장치는 냉장실의 도어의 내측에 물통을 안착하여 도어의 외부에서 냉각된 물을 편리하게 받아 마실 수 있게 하고, 적어도 물을 마시기 위한 목적으로 도어를 개방하는 횟수를 감소시킴으로써 냉기의 손실을 감소시켜 절전효과를 얻을 수 있도록 한 것이다.In general, the water supply for the refrigerator seats the bucket inside the door of the refrigerating compartment to conveniently receive the water cooled from the outside of the door, and at least by reducing the number of opening the door for the purpose of drinking water It is to reduce the loss of cold air to achieve a power saving effect.
제1도는 일반적인 냉장고용 물 공급장치를 나타낸 것이다.1 shows a general water supply device for a refrigerator.
즉, 도어(10)를 관통하게 설치되는 급수관(20)은 도어의 내측에 형성되어 물통(30)이 안착되는 출수구(21)와 물통의 물이 공급되는 급수구(22)로 이루어져 있다.That is, the water supply pipe 20 installed to penetrate the door 10 includes a water outlet 21 formed at an inner side of the door to which the water tank 30 is seated, and a water supply hole 22 to which water from the water tank is supplied.
급수관(20)의 내부에는 상기 물통(30)의 출수구측에 형성된 밸브(31)를 개폐토록 피스톤(23)이 슬라이딩 되게 설치되고, 이 피스톤의 선단부는 급수실(40)에 노출되게 설치된 급수레버(41)에 연결되며, 피스톤의 후단부에는 탄성스프링(24)이 개재 되어 있다.In the water supply pipe 20, a piston 23 is installed to slide the valve 31 formed at the outlet port side of the water tank 30 so as to open and close, and a water supply lever provided so that the front end of the piston is exposed to the water supply chamber 40. It is connected to (41), the rear end of the piston is interposed with an elastic spring (24).
따라서, 급수레버(41)를 동작시켜 이에 연결된 피스톤(23)을 급수관(20)내에서 후퇴시키면 물통(30)의 밸브(31)를 눌러주게 되어 출구가 개방됨으로써 출수구(21)와 급수구(22)를 통하여 물이 배수된다.Thus, when the water supply lever 41 is operated and the piston 23 connected thereto is retracted in the water supply pipe 20, the valve 31 of the water tank 30 is pressed to open the outlet so that the outlet 21 and the water supply port ( Water is drained through 22).
또한, 급수레버(41)에 가했던 힘을 제거하면 탄성스프링(24)의 복원력에 의해 피스톤(23)이 복귀동작을 하여 밸브(31)를 닫아주게 되는 것이다.In addition, when the force applied to the water supply lever 41 is removed, the piston 23 moves by the restoring force of the elastic spring 24 to close the valve 31.
그러나 상기와 같은 종래의 물 공급장치는 매우 복잡한 구조로 되어 있고, 이에 비례하여 많은 부속품들로 이루어져 있으므로 조립공정이 늘어날 뿐만 아니라 생산원가가 상승되는 문제점이 발생되었다However, the conventional water supply device as described above has a very complicated structure, and in proportion to this, there are many accessories, which increases the assembly process and increases the production cost.
또한, 수평운동을 하는 피스톤이 상·하 동작되는 밸브를 개폐하는 과정에서 수직응력 및 마찰력 등에 의해 작동상에 무리가 따르게 되고, 이러한 상태로 장기간 사용할 때에는 피스톤의 급격한 마모로 인하여 밸브의 개폐동작이 불량해 지는 원인이 되어 출수구측으로 레버의 동작과는 무관하게 물이 새는 누수현상과 급수관이 수평으로 설치되는 구조적인 문제점으로 인하여 관내의 물이 원활히 배수되지 않는 잔수현상이 발생되었는데, 이렇게 장기간동안 잔수되어 있던 물은 오염의 우려가 있었고, 그 물을 마실 경우 건강에 해로운 영향을 미치는 등의 문제점들이 있었다.In addition, in the process of opening / closing a valve in which a horizontal piston moves up and down, it is difficult to operate due to vertical stresses and frictional forces. Due to the problem of water leak and leakage of the water irrespective of the lever operation to the outlet side and the structural problem that the water supply pipe is installed horizontally, the residual water phenomenon that the water in the pipe cannot be drained smoothly occurred. There was a concern that the water had been polluted, and drinking the water had a harmful effect on health.
본 발명은 위와 같은 종래의 물 공급장치의 문제점들을 감안하여 안출한 것으로서, 간단한 구조로 제작하여 동작과정을 단순화 할 수 있는 냉장고용 물 공급장치를 제공하는 것을 그 목적으로 한다.The present invention has been made in view of the problems of the conventional water supply device as described above, it is an object of the present invention to provide a refrigerator water supply device that can simplify the operation process by making a simple structure.
본 발명의 다른 목적은 간단한 구조로 되어 부품수를 줄일 수 있는 물 공급장치를 제공함에 있다.Another object of the present invention is to provide a water supply device that can be a simple structure to reduce the number of parts.
이러한 목적들을 달성하기 위한 본 발명은 스위치의 감지동작에 의해 승강수단이 상·하 운동되어 밸브를 개폐함으로써 물을 급수 또는 단수되게 하는 급수동작의 단순화로 동작상의 불량율을 감소시키고, 구조의 간소화로 부품수를 줄일 수 있는 것을 그 특징으로 한다.The present invention for achieving the above object is to reduce the failure rate in operation by the simplification of the water supply operation to the water supply or singular water by opening and closing the valve by opening and closing the lifting means by the sensing operation of the switch, to simplify the structure The number of parts can be reduced.
이하, 본 발명의 냉장고의 물 공급장치를 첨부된 도면을 참조하여 상세히 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings, the water supply of the refrigerator of the present invention will be described in detail.
제2도와 제3도는 본 발명 실시예의 물 공급장치가 설치된 냉장고를 나타낸 사시도와, 물 공급장치를 발췌한 측단면도로서, 도어(100)의 내측에 수직방향으로 설치된 급수관(200)은 상단에 물통(600)이 설치되는 안착부(210)와, 측면으로부터 비스듬히 연장되어 상기 도어(100)의 내측에서 외측을 향해 관통되게 설치된 출수구(240)가 일체로 형성되어 있다.2 and 3 are perspective views showing a refrigerator having a water supply device according to an embodiment of the present invention, and a side cross-sectional view of the water supply device, wherein a water supply pipe 200 installed in a vertical direction inside the door 100 has a water tank at an upper end thereof. The seating portion 210 is provided with a 600, and the water outlet 240 is installed integrally extending obliquely from the side to penetrate toward the outside from the inside of the door 100.
상기 급수관(200)의 내부에는 제1축(300)과 제2축(400)이 분리되게 동심선상의 상·하로 설치되어 있고, 관 내벽으로는 제2축(400)의 승강운동에 의해 개폐되는 차단막(220)이 형성되며, 그 밑에는 상기 급수관(200)의 내벽으로 제2걸림편(230)들이 적어도 3곳 이상 돌출되게 형성되어 있다Inside the water supply pipe 200, the first shaft 300 and the second shaft 400 are installed up and down concentrically, and the inner wall of the water supply pipe 200 is opened and closed by lifting and lowering of the second shaft 400. The blocking film 220 is formed, and below the second catching pieces 230 are formed to protrude at least three places into the inner wall of the water supply pipe 200.
또한, 방수부재(512)로 보호되어 관내의 물로부터 차단되도록 한 플런져(511)를 상·하 운동되게 하는 승강수단(500)이 급수관(200)의 외부 끝단에 설치되는데, 급수실(110)의 내부에 설치된 동작스위치(120)에 의해 제어된다.In addition, the lifting means 500, which is protected by the waterproof member 512 to allow the plunger 511 to be blocked up and down from the water in the pipe, is installed at the outer end of the water supply pipe 200. It is controlled by the operation switch 120 installed inside.
제1축(300)은 상단에 물통(600)의 출구를 개폐하는 제1밸브(310)가 착설되고 동축상의 하단 외주면을 따라 적어도 3곳 이상에 제1걸림편(330)들이 돌축되게 형성되며, 이 걸림편들과 상기 제1밸브(310)와의 사이에 자체 탄성력에 의해 제1축(300)을 복귀시키는 제1탄성스프링(320)이 개재되어 있다.The first shaft 300 has a first valve 310 for opening and closing the outlet of the bucket 600 at the top and the first catching pieces 330 are formed in at least three locations along the outer circumferential surface of the coaxial shaft. A first elastic spring 320 is disposed between the locking pieces and the first valve 310 to return the first shaft 300 by its elastic force.
한편, 제1축(300)의 동심선상의 하부측에 설치되는 제2축(400)은 상단으로 걸림편(330)들에 상응하는 개수로 돌출편(410)들이 축의 외주면에 형성되고, 이 돌출편의 밑에는 차단막(220)을 개폐하는 제2밸브(420)가 동축상으로 결합되어 있다.On the other hand, the second shaft 400, which is installed on the lower side of the concentric line of the first shaft 300, the protrusion pieces 410 are formed on the outer circumferential surface of the shaft in the number corresponding to the engaging pieces 330 to the top, Under the protruding piece, a second valve 420 for opening and closing the blocking film 220 is coaxially coupled.
또한, 상기 제2걸림편(230)들과 축 하단과의 사이에는 제2축(400)을 복귀동작되게 하는 제2탄성스프링(430)이 개재되어 있다.In addition, a second elastic spring 430 is disposed between the second catching pieces 230 and the lower end of the shaft to return the second shaft 400 to the return operation.
제4도는 본 발명 실시예의 동작상태를 나타낸 것으로서, (a)는 동작전의 상태를, (b)는 동작중의 상태를 나타낸 것이다.4 shows an operating state of the embodiment of the present invention, where (a) shows a state before the operation and (b) shows a state during operation.
먼저, 작동과정을 설명하면 다음과 같다.First, the operation process is as follows.
급수실(110)에 컵 등의 물을 수용할 수 있는 용기(A)를 밀어 넣어 스위치(120)를 접속시키면 승강수단(500)에 의해 플런져(511)를 상승시키게 되는데, 자력발생의 유·무에 의해 간단히 상·하 동작될 수 있는 솔레노이드를 설치하는 것이 바람직하나 비교적 간단한 방법으로 승강동작되는 방법의 것이면 이에 한정하지 않는다.When the container A capable of accommodating water such as a cup is pushed into the water supply chamber 110 to connect the switch 120, the plunger 511 is raised by the elevating means 500. It is preferable to install a solenoid that can be simply operated up and down by nothing, but it is not limited to the method of elevating operation by a relatively simple method.
상기의 플런져(511)가 제2축(400)의 하단면을 밀어 올려주면 제2밸브(420)가 차단막(220)으로부터 이격되어 급수관(200)이 개방되며, 이에 제2축(400)이 제1축(300)을 밀어 올려주는 연동작용으로 물통(600)의 출구를 막고 있는 제1밸브(310)가 개방됨으로써 비로소 물이 유출될 수 있는 관로가 개방된다.When the plunger 511 pushes up the bottom surface of the second shaft 400, the second valve 420 is spaced apart from the blocking film 220 to open the water supply pipe 200, and thus the second shaft 400 is opened. By opening the first valve 310 blocking the outlet of the bucket 600 by the interlocking action to push up the first shaft 300, the pipeline through which water can flow is opened.
이와 같이 개방된 관로를 따라 물이 흘러 내릴 때, 제1걸림편(330) 및 돌출편(410), 제2걸림편(230)들의 사이로 골고루 분배된 물이 최종적으로 출수구(240)를 통해 배출되는데, 이러한 동작은 동작스위치(120)를 누르고 있는 동안은 지속된다.When water flows along the open pipe in this way, the water evenly distributed between the first catching piece 330, the protruding piece 410, and the second catching piece 230 is finally discharged through the water outlet 240. This operation is continued while the operation switch 120 is pressed.
제5도는 본 발명의 물 공급장치의 다른 실시예를 나타낸 일부절취 단면도로서, 승강수단(500)에 의해 물통(600)을 개폐하는 동작구조는 전술한 바와 동일하되, 플런져(511)의 유동이 가능하고 관로의 물이 유입되지 않토록 방수처리된 방수부재(512)가 씌워지는데, 이 방수부재는 플런져(511)의 상·하 운동시 접히고 펴질 수 있는 자바라 형태로 하는 것이 바람직하다.Figure 5 is a partial cutaway cross-sectional view showing another embodiment of the water supply apparatus of the present invention, the operation structure for opening and closing the water bottle 600 by the lifting means 500 is the same as described above, the flow of the plunger 511 The waterproof member 512 is covered with a waterproof member 512 to prevent water from flowing into the pipeline, and the waterproof member is preferably in a bellows shape that can be folded and unfolded during the up and down movement of the plunger 511. .
이와 같은 본 고안은 급수관이 일체형의 단순한 수직구조로 설치됨으로써 급수관 내에 물이 잔류되는 잔수현상을 방지함과 아울러, 급수관에 내재되는 부품수를 줄여서 동작을 단순화 함으로써 누수현상 등의 불량율을 현저히 감소시켜 제품의 신뢰성을 향상시키며, 제작비용의 절감과 생산성을 향상시킬 수 있는 효과를 얻을 수 있다.The present invention prevents the residual water phenomenon remaining in the water supply pipe by installing the water supply pipe in a simple vertical structure, and reduces the number of parts inherent in the water supply pipe and simplifies the operation, thereby significantly reducing the defective rate such as water leakage. The reliability of the product can be improved, and the production cost can be reduced and the productivity can be improved.
