It is.

일반적인 냉장고의 구성은, 도 1에 도시된 바와 같이, 냉장실 후벽 일측에 냉장고 외부의 급수장치(미도시)로부터 공급받은 물을 여과해 주는 필터(1)가 설치되어 있고, 상기 필터(1)의 하측에는 급수밸브(10)가 설치되어 있으며, 상기 급수밸브(10) 하측에는 물탱크(2)가 설치되어 일정량의 물을 저장한다.As shown in FIG. 1, a typical refrigerator includes a filter 1 that filters water supplied from a water supply device (not shown) outside the refrigerator, on one side of the rear wall of the refrigerating chamber. A water supply valve 10 is installed at a lower side, and a water tank 2 is installed at a lower side of the water supply valve 10 to store a predetermined amount of water.

그리고 냉동실 내측의 일단부에는 상기 급수밸브(10)와 배관을 통해 연통 형성되는 제빙기(3)가 설치되어 있고, 상기 제빙기(3)의 하측에는 제빙된 얼음을 저장하는 용기(4)가 구비되어 있고, 냉장실 도어의 전면 일측 구간에는 배관을 통해 상기 물탱크(2)와 연통 형성된 디스펜서(5)가 설치되어 있으며, 상기 디스펜서(5)의 상부에는 전면판넬을 설치하여 사용자가 원하는 것을 선택할 수 있도록 버튼(미도시) 등이 형성되어 있다.An ice maker 3 is formed at one end of the inside of the freezing chamber through communication with the water supply valve 10, and a container 4 for storing iced ice is provided below the ice maker 3. In addition, a dispenser 5 formed in communication with the water tank 2 is installed at one side of the front side of the refrigerating compartment door, and a front panel is installed at the upper portion of the dispenser 5 so that the user can select a desired one. Buttons (not shown) and the like are formed.

이와 같은 일반적인 냉장고에 있어서 종래 급수밸브의 구조를 도 2에 의거하여 설명하면, 크게 냉장고 외부의 급수장치(미도시)로부터 급수받은 물을 일정 시간 저장하는 급수실(11)과, 그 급수실(11)로부터 공급받은 물을 제빙기(3) 또는 디스펜서(5)로 공급해 주는 기계실(15)로 구분할 수 있다.In the conventional refrigerator, a structure of a conventional water supply valve will be described with reference to FIG. 2. The water supply chamber 11 which stores water supplied from a water supply device (not shown) outside the refrigerator for a predetermined time, and the water supply chamber ( 11) can be divided into the machine room 15 for supplying the water supplied from the ice maker (3) or the dispenser (5).

상기 급수실(11)은 배관을 통해 공급되는 물을 유입하는 급수구(12)와, 일측에 급수필터(13a)와 플로우와셔(13b)가 구비된 유출구(14)로 구성된다.The water supply chamber 11 is composed of a water supply port 12 for introducing water supplied through the pipe, and an outlet 14 provided with a water filter 13a and a flow washer 13b on one side.

상기 기계실(15)은 상기 유출구(14)를 통해 제빙기(3)로 공급되는 방향에 스프링(17)에 의해 탄력 설치되어 있는 플런저(18)와, 그 플런저(18) 상부에 전원의 공급유무에 따라 개폐되는 솔레노이드밸브(16)와, 상기 플런저(18) 하부에 디스펜서(5)로 물을 공급하기 위한 배수구(19)로 구성되어 있다.The machine room 15 has a plunger 18 elastically installed by a spring 17 in a direction to be supplied to the ice maker 3 through the outlet 14, and whether or not power is supplied to the upper part of the plunger 18. The solenoid valve 16 is opened and closed, and the drain port 19 for supplying water to the dispenser 5 under the plunger 18.

이와 같이 구성된 일반적인 냉장고용 급수진행구조의 작용에 대해서 설명하면 다음과 같다.Referring to the operation of the water supply structure for a general refrigerator configured as described above are as follows.

전원이 인가되어 냉장고 외부의 수도꼭지 등의 급수장치(미도시)에 연결 설치된 배관을 통해 일정량의 물이 급수되면, 급수된 물은 냉동실 후벽에 설치된 필터(1)에서 여과되고 여과된 물은 급수밸브(10)의 급수구(12)를 통해 급수실(11)로 유입된다.When a certain amount of water is supplied through a pipe connected to a water supply device (not shown), such as a faucet outside the refrigerator, the water supplied is filtered by the filter (1) installed on the rear wall of the freezer and the filtered water is supplied to the water supply valve. It flows into the water supply chamber 11 through the water supply port 12 of (10).

상기 급수실(11)로 유입된 물은 급수필터(13a)와 플로우와셔(13b)를 거쳐 유출구(14)를 통해 기계실(15)로 공급되고, 전원이 인가되지 않은 상태에서 배수구(19)를 막고 있던 플런저(18)가 스프링(17)의 탄력에 의해 수직 왕복 운동을 함으로써 배수구(19)로 물을 배수시켜 일정한 유량으로 디스펜서(5)로 공급하며, 소정의 마이콤(미도시)에 의해 제빙신호가 솔레노이드밸브(16)에 전달되면, 그 신호를 받은 솔레노이드밸브(16)가 수평운동에 의해 개방되면서 물을 제빙기(3)로 유입시켜 얼음을 얼리게 한다.The water introduced into the water supply chamber 11 is supplied to the machine room 15 through the outlet 14 through the water filter 13a and the flow washer 13b, and the drain 19 is not supplied with power. The plunger 18 which has been blocked is drained to the drain port 19 by vertical reciprocating motion by the elasticity of the spring 17, and is supplied to the dispenser 5 at a constant flow rate, and deiced by a predetermined microcomputer (not shown). When the signal is transmitted to the solenoid valve 16, the solenoid valve 16 receiving the signal is opened by the horizontal movement while the water flows into the ice maker (3) to freeze the ice.

그후, 급수밸브(10)는 제빙기(3)에 일정한 양의 얼음이 제빙될 때까지 계속적으로 급수가 이루어지고, 사용자가 디스펜서(5)에서 물을 취출하게 되면 소정량의 물이 취출된 물탱크(2) 내에 물의 양을 항상 일정하게 공급해 준다.Thereafter, the water supply valve 10 is continuously supplied with water until a predetermined amount of ice is iced in the ice maker 3, and when the user draws water from the dispenser 5, the water tank from which a predetermined amount of water is drawn out (2) Always supply a constant amount of water.

이렇게 저장용기(4)에 소정량의 얼음이 저장된 상태에서 사용자가 누름버튼(미도시)을 누르게 되면, 별도의 이송장치가 작동하여 얼음을 취출구로 내보내게 된다.When a user presses a push button (not shown) in a state where a predetermined amount of ice is stored in the storage container 4, a separate transfer device operates to discharge the ice to the outlet.

그러나, 종래 기술은 사용자가 수도꼭지를 열어 놓지 않았거나 냉장실 일측 구간의 물탱크(2)에 물이 없을 경우, 얼음이 제빙되지 않거나 디스펜서(5) 사용시 물이 취출되지 않는 문제점이 있었다.However, the conventional technology has a problem in that when the user does not open the faucet or when there is no water in the water tank 2 in one side of the refrigerating chamber, ice is not iced or water is not taken out when the dispenser 5 is used.

본 발명은 상술한 종래의 문제점을 개선하기 위해 안출된 것으로, 급수행정시 일정시간 동안에 솔레노이드가 작동하지 않을 경우에는 급수가 진행되지 않는 것으로 판단하여 사용자에게 알려줌으로써 사용자로 하여금 제품에 대한 진단 조치를 할 수 있도록 한 냉장고의 급수제어방법을 제공하는데 목적이 있다.The present invention has been made to improve the above-mentioned conventional problems, and when the solenoid does not operate for a predetermined time during the water supply administration, it is determined that the water supply does not proceed so that the user can diagnose the product. It is an object of the present invention to provide a water supply control method for a refrigerator.

And an output device 33 for outputting the signal controlled at 32 to the water supply valve 10.

상기와 같이 구성된 본 발명에 의한 냉장고용 급수밸브의 작용에 대해서 설명하면 다음과 같다.Referring to the operation of the water supply valve for a refrigerator according to the present invention configured as described above are as follows.

전원이 인가되어 냉장고 외부의 수도꼭지 등의 급수장치(미도시)에 연결 설치된 배관을 통해 일정량의 물이 급수되면, 급수된 물은 냉동실 후벽에 설치된 필터(1)에서 필터링되고 필터링된 물은 급수밸브(10)의 급수구(12)를 통해 급수실(11)로 유입된다.When power is supplied and water is supplied to a certain amount of water through a pipe connected to a water supply device (not shown) such as a faucet outside the refrigerator, the water supplied is filtered by the filter (1) installed on the rear wall of the freezer and the filtered water is supplied to the water supply valve. It flows into the water supply chamber 11 through the water supply port 12 of (10).

상기 급수실(11)로 유입된 물은 급수필터(13a)와 플로우와셔(13b)를 거쳐 유출구(14)를 통해 기계실(15)로 공급되고, 전원이 인가되지 않은 상태에서 배수구(19)를 막고 있던 플런저(18)가 스프링(17)의 탄력에 의해 수직 왕복 운동을 함으로써 배수구(19)로 물을 배수시켜 일정한 유량으로 물탱크(2)와 제빙기(3)로 공급한다.The water introduced into the water supply chamber 11 is supplied to the machine room 15 through the outlet 14 through the water filter 13a and the flow washer 13b, and the drain 19 is not supplied with power. The blocked plunger 18 performs vertical reciprocation by the elasticity of the spring 17 to drain the water to the drain port 19 and supply it to the water tank 2 and the ice maker 3 at a constant flow rate.

그후, 급수밸브(10)는 제빙기(3)에 일정한 양의 얼음이 제빙될 때까지 계속적으로 급수가 이루어지고, 사용자가 디스펜서(5)에서 물을 취출하게 되면 소정량의 물이 취출된 물탱크(2) 내에 물의 양을 항상 일정하게 공급해 준다.Thereafter, the water supply valve 10 is continuously supplied with water until a predetermined amount of ice is iced in the ice maker 3, and when the user draws water from the dispenser 5, the water tank from which a predetermined amount of water is drawn out (2) Always supply a constant amount of water.
