본 발명은 냉장고 도어스위치에 관한 것으로, 더욱 상세하게는 냉동, 냉장실 램프와 팬모터를 제어하는 도어스위치내에 전기적으로 차단되는 격벽을 설치함으로서 AC(교류)와 DC(직류)전원을 하나의 도어스위치에 혼용이 가능하도록 한 냉장고 도어스위치 장치에 관한 것이다.The present invention relates to a refrigerator door switch, and more particularly, by installing a partition wall which is electrically disconnected in a door switch for controlling a refrigerator and a refrigerator compartment lamp and a fan motor, the AC (AC) and DC (DC) power supply is a single door switch. It relates to a refrigerator door switch device that can be mixed.

냉장고의 도어스위치는, 냉장고 도어의 개폐상태를 감지하여 냉장고내의 램프점등과 팬모터의 구동여부 등에 대한 제어를 하게된다. 종래의 냉장고 도어스위치를 도면을 통하여 살펴보기로 한다.The door switch of the refrigerator detects the opening / closing state of the refrigerator door and controls the lamp lighting in the refrigerator and whether the fan motor is driven. A conventional refrigerator door switch will be described with reference to the drawings.

제1도는 종래의 냉장고 도어스위치 내부 구조를 보인 정면도이고, 제2도는 제1도의 회로도이다. 제2도의 회로도에서 도시된 바와 같이 램프는 한 개로 구성되어 있으며, 본 램프는 냉장실내에 설치된 램프를 의미하며 이하 설명에서 램프는 냉장실 램프를 의미하는 것으로 사용하기로 한다.FIG. 1 is a front view showing the internal structure of a conventional refrigerator door switch, and FIG. 2 is a circuit diagram of FIG. As shown in the circuit diagram of FIG. 2, the lamp is composed of one, and this lamp means a lamp installed in a refrigerating chamber, and in the following description, a lamp means a refrigerating chamber lamp.

종래의 냉장고에 있어 도어의 개폐에 따라 고내의 팬모터(M) 및 램프(L)를 동작시키기 위한 도어스위치의 구성은, 크기 누름버튼(1,1′), 상기 누름버튼(1,1′)에 의해 작동되는 가동편(4,5), 외부전원을 공급하는 전원입력단자(9), 및 전원입력단자와 가동편의 연결을 위한 접속단자(6,7,8)로 이루어진다.In the conventional refrigerator, the door switch for operating the fan motor (M) and the lamp (L) in the refrigerator in accordance with the opening and closing of the door, the size push button (1, 1 '), the push button (1, 1' A movable piece (4, 5) operated by a), a power input terminal (9) for supplying external power, and connection terminals (6, 7, and 8) for connecting the power input terminal and the movable piece.

먼저, 도어스위치의 케이스(10) 일측에 형성된 홈을 통하여 냉동실용누름버튼(1)과 냉장실용 누름버튼(1′)이 설치되며, 상기 누름버튼(1,1′)내부에는 스프링(3)이 탄지되어 있다. 상기 누름버튼(1,1′)의 선단이 각각 냉동실, 냉장실 도어와 접촉되어 각 도어가 닫혔을 때에는 상기 누름버튼(1,1′)은 눌려진 상태가 되고, 도어가 열렸을 때는 스프링(3)의 탄성에 의해 상기 누름버튼(1,1′)은 돌출된 상태가 된다.First, a freezer compartment push button 1 and a refrigerator compartment pushbutton 1 'are installed through a groove formed at one side of the case 10 of the door switch, and a spring 3 is provided inside the pushbuttons 1 and 1'. This is tanned. When the front ends of the push buttons 1, 1 'are in contact with the freezer compartment and the refrigerating compartment doors, respectively, the push buttons 1, 1' are pressed, and when the door is opened, the spring 3 The push buttons 1, 1 'are protruded by elasticity.

그리고, 상기 누름버튼(1,1′)의 하부 일측에는 캠(2)이 설치되어 상기 누름버튼(1,1′)의 작동과 연동되어 움직이며, 상기 램(2)의 작동에 의해 동작하며 탄성력이 있는 가동편(4,5)이 캠(2)과 맞물려 각각 설치되어 있다.And, the lower side of the push button (1, 1 ') is provided with a cam (2) moves in conjunction with the operation of the push button (1, 1'), the operation by the operation of the ram (2) The movable pieces 4 and 5 with elastic force are provided in engagement with the cam 2, respectively.

한편, 외부전원에 의한 전원을 공급하는 전원입력단자(9)가 탄성력을 갖는 제1 가동편(4)의 일단부와 용접 등을 통하여 연결되고, 상기 제1 가동편(4)의 접촉부(4a)는 제2도의 팬모터(M)와 연결된 팬모터 접속단자(6)의 접촉부(6a)와 접촉되도록 설치되어 있다. 그리고 상기 제1 가동편(4)의 접촉부(4a) 일측에는 접속단자(8)의 접촉부(8a)가 근접되어 위치하며, 상기 접속단자(8)의 단부는 제2 가동편(5)의 단부와 용접 등에 의해 연결되고, 상기 제2 가동편(5)의 접촉부(5a)는 제2도의 램프와 연결된 램프 접속단자(7)의 접촉부(7a)에 근접되도록 설치되어 있다.On the other hand, the power input terminal 9 for supplying power by an external power source is connected to one end of the first movable piece 4 having elastic force by welding or the like, and the contact portion 4a of the first movable piece 4 is connected. ) Is installed in contact with the contact portion 6a of the fan motor connection terminal 6 connected to the fan motor M of FIG. The contact portion 8a of the connecting terminal 8 is located close to one side of the contact portion 4a of the first movable piece 4, and the end of the connecting terminal 8 is an end portion of the second movable piece 5. And a contact portion 5a of the second movable piece 5 are provided to be close to the contact portion 7a of the lamp connecting terminal 7 connected to the lamp of FIG.

상기와 같은 구조로 이루어진 종래의 냉장고용 도어스위치의 동작을 설명하기로 한다. 냉장실도어 및 냉동실도어가 모두 닫혔을 때 즉, 냉동실용 누름버튼(1)과 냉장실용 누름버튼(1′)이 눌러진 상태에서는 각 누름버튼(1′) 하부에 위치한 캠(2,2′)이 회전함에 의해 제1 가동편(4)은 램프접속단자(6)와 떨어지고 접속단자(8)와 접촉되고, 제2 가동편(5)은 팬모터접속단자(7)에 접촉된다.The operation of the conventional door switch for a refrigerator having the structure as described above will be described. When both the refrigerator door and the freezer door are closed, that is, when the freezer push button 1 and the freezer push button 1 'are pressed, the cams (2,2') located below each push button 1 'are pressed. By this rotation, the first movable piece 4 is separated from the lamp connecting terminal 6 and is in contact with the connecting terminal 8, and the second movable piece 5 is in contact with the fan motor connecting terminal 7.

이때 전원입력단자(9)로 입력된 전원은 제1 가동편(4)으로 전달되며, 상기 제1 가동편(4)은 접속단자(8)과 접촉되므로 접속단자(8)를 지나 제2 가동편(5)으로 전달된 후, 제2 가동편(5)과 연결된 팬모터접속단자(7)에 전달되어 팬모터(M)가 구동된다. 한편, 상기의 경우 제1 가동편(4)과 떨어지게 된 램프접속단자(6)로는 전원이 공급되지 않아 램프(L)는 작동되지 않는다.At this time, the power input to the power input terminal 9 is transmitted to the first movable piece 4, the first movable piece 4 is in contact with the connecting terminal 8, so that the second movable through the connecting terminal 8 After being transferred to the piece 5, the fan motor M is driven by being transferred to the fan motor connecting terminal 7 connected to the second movable piece 5. On the other hand, in the above case, since the power is not supplied to the lamp connection terminal 6 separated from the first movable piece 4, the lamp L is not operated.

이와는 달리 각 도어를 모두 열었을 경우, 즉, 냉동실용 누름버튼(1)과 냉장실용 누름버튼(1′)이 눌러지지 않은 상태에서는 제1 가동편(4)은 램프접속단자(6)와 접촉되는 반면에 제2 가동편(5)은 팬모터접속단자(7)와 떨어진 상태가 된다. 상기의 경우 전원입력단자(9)로부터 공급된 전원은 제1 가동편(4)을 지나 램프접속단자(6)로 전달되어 램프가 작동되어 불이 켜지게 된다.On the contrary, when all the doors are opened, that is, when the freezer push button 1 and the freezer push button 1 'are not pressed, the first movable piece 4 is in contact with the lamp connection terminal 6. On the other hand, the second movable piece 5 is separated from the fan motor connecting terminal 7. In this case, the power supplied from the power input terminal 9 is passed through the first movable piece 4 to the lamp connection terminal 6 so that the lamp is activated and the light is turned on.

다음은 냉장실도어만 열였을 경우, 즉, 냉동실용 누름버튼(1)은 눌러진 상태이고 냉장실용 누름버튼(1′)은 눌러지지 않은 상태에서는 팬모터접속단자(7)로는 전원이 공급되지 않아 팬모터(M)는 작동되지 않으며, 램프접속단자(6)로는 전원이 공급되어 램프(L)는 작동된다. 이번에는 냉동실도어만 열렸을 경우, 즉, 냉동실용 누름버튼(1)은 눌러지지 않은 상태이며 냉장실용 누름버튼(1′)은 눌러진 상태에서는 팬모터접속단자(7)와 램프접속단자(6) 양 단자 모두에 전원이 공급되지 않아 팬모터(M)와 램프(L)는 작동되지 않는다.Next, when only the refrigerator door is opened, that is, when the freezer push button 1 is pressed and the refrigerator push button 1 'is not pressed, power is not supplied to the fan motor connection terminal 7. The fan motor M is not operated, and power is supplied to the lamp connection terminal 6 so that the lamp L is operated. This time, when only the freezer door is opened, that is, the freezer push button 1 is not pressed and the freezer push button 1 'is pressed, the fan motor connection terminal 7 and the lamp connection terminal 6 are pressed. Fan motor (M) and lamp (L) do not operate because power is not supplied to both terminals.

이상에서 설명한 종래 냉장고의 도어스위치 장치에서는 다음과 같은 문제점이 발생한다.The following problems occur in the door switch device of the conventional refrigerator described above.

상기의 경우 제2도에 도시된 회로도에 나타난 바와같이 팬모터와 램프는 단일 전원에 연결되어 작동되므로 AC(교류) 또는 DC(직류)중 어느 하나의 전원을 공급하여 작동하게 된다.In the above case, as shown in the circuit diagram shown in FIG. 2, the fan motor and the lamp are connected to a single power source, and thus operate by supplying power of either AC (AC) or DC (DC).

또한, 최근에는 냉장실램프 뿐만 아니라 냉동실램프가 각각 구비된 냉장고도 출시되고 있으나, 이역시 외부전원단자가 냉동실램프, 냉장실램프 및 팬모터가 일체형으로 이루어져 있기 때문에 이러한 형태이 도어스위치는 AC(교류) 또는 DC(직류)전용으로 회로가 구성될 수 밖에 없다. 그 이유는 예를 들어 AC 220V가 냉동실램프와 냉장실램프에 연결되고 DC 4.5V가 팬모터단자에 입력되면, 전원입력단자가 공용이기 때문에 마이컴으로 입력되는 팬모터-전원입력단자는 냉장실, 냉동실램프와 전원입력단자의 고전압 때문에 마이컴이 충격을 받아서 마이컴 자체를 못쓰게 되는 원인이 된다.In addition, in recent years, not only refrigerator lamps but also refrigerators equipped with freezer lamps have been released. However, since the external power terminal is made of a freezer lamp, a refrigerator lamp and a fan motor, this type of door switch is AC (AC) or The circuit must be configured for DC (direct current) only. The reason is, for example, if AC 220V is connected to the freezer lamp and the refrigerating lamp, and DC 4.5V is input to the fan motor terminal, because the power input terminal is common, the fan motor-power input terminal input to the microcomputer is the refrigerator compartment, the freezer lamp. Due to the high voltage of the power input terminal and the microcomputer, the microcomputer is shocked and the microcomputer itself cannot be used.

상기의 문제점을 해결하기 위한 수단으로서 종래 냉장고에서는 AC(교류)와 DC(직류)를 혼용해서 사용하기 위해서는 냉동실, 냉장실 도어스위치를 각각 별도로 두 개를 설치하여 사용하여야 하는 불편함이 있다.As a means for solving the above problems, in order to use a mixture of AC (AC) and DC (DC) in the conventional refrigerator, it is inconvenient to use two separate freezer and refrigerator door switches.

본 발명은 상기의 문제점을 해결하기 위한 것으로, 하나의 도어스위치 내에 회로분리용 격벽을 설치하여 각기 다른 회뢰의 전원단자를 인출함으로서 AC(교류)와 DC(직류)를 혼용해 사용할 수 있는 냉장고 도어스위치 장치를 제공하는 것을 목적으로 한다.The present invention is to solve the above problems, by installing a circuit separation partition in one door switch to draw the power supply terminals of different lightning, the refrigerator door that can be used mixed AC (DC) and DC (direct current) It is an object to provide a switch device.

상기 목적을 달성하기 위한 본 발명에 의한 냉장고 도어스위치는, 냉장고 도어의 개폐에 따라 작동되는 냉동, 냉장실용 누름버튼과; 외부에서부터 제1전원을 입력하는 제1 전원 입력단자와; 외부에서부터 제2 전원을 입력하는 제2 전원 입력단자와; 상기 제1 전원 입력단자와 연결되고, 입력되는 제1 전원을 팬모터로 인가하는 팬모터가동편과; 상기 제2 전원 입력단자와 연결되고, 상기 팬모터 가동편과 상반되게 작용하며 냉장실 도어의 개폐동작에 따라 상기 입력되는 제1 전원을 냉장실 램프로 인가하는 냉장실 램프가동편과; 상기 제2 전원 입력단자와 연결되고, 상기 팬모터 가동편과 상반되게 작용하며 냉동실 도어의 개폐동작에 따라 상기 입력되는 제1 전원을 냉동실 램프로 인가하는 냉동실 램프가동편; 으로 구성되어 상기 제1 전원 입력단자와 제2 전원 입력단자는 전기적으로 차단 가능한 격벽에 의해 분리되어 하나의 도어 스위치내에 교류와 직류가 혼용되어 사용가능한 것을 기술적 요지로 하고 있다.Refrigerator door switch according to the present invention for achieving the above object, the push button for the freezer, refrigerator compartment operating in accordance with opening and closing of the refrigerator door; A first power input terminal for inputting a first power source from the outside; A second power input terminal for inputting a second power source from the outside; A fan motor moving piece connected to the first power input terminal and configured to apply an input first power to the fan motor; A refrigerating compartment lamp movable piece connected to the second power input terminal and acting opposite to the fan motor movable piece and applying the input first power to a refrigerating compartment lamp according to an opening / closing operation of a refrigerating compartment door; A freezer compartment lamp moving piece connected to the second power input terminal and operating opposite to the fan motor movable piece and applying the input first power to a freezer compartment lamp according to an opening / closing operation of a freezer compartment door; The first power input terminal and the second power input terminal is separated by an electrically disconnectable partition, and the technical gist of the present invention allows the use of a mixture of alternating current and direct current in one door switch.

그리고, 상기 제1 전원과 제2 전원은 그 성질이 서로 다른 것을 이용하거나 또는 그 성질이 서로 같은 것을 이용한다.The first power supply and the second power supply use different properties or use the same property.

상기 각 누름버튼의 일측에는 지지편이 형성되며, 상기 누름버튼의 작동에 따라 팬모터가동편이 제1 전원입력단자에 연동되도록 하는 제1 돌기와 램프 가동편이 제2 입력단자에 연동되도록 하는 제2 돌기가 상기 지지편에 형성된다. 그리고, 상기 누름버튼이 모두 눌러졌을 때에만 팬모터가동편이 제1 전원입력단자에 연결되어 팬모터가 작동된다. 상기 누름버튼이 눌러지지 않았을 때, 램프가동편이 제2 전원 입력단자에 연결되어 램프가 작동된다.A support piece is formed at one side of each push button, and the first protrusion for allowing the fan motor moving piece to be interlocked with the first power input terminal and the second protrusion for allowing the lamp movable piece to be interlocked with the second input terminal according to the operation of the push button. Is formed on the support piece. The fan motor is connected to the first power input terminal only when all the push buttons are pressed to operate the fan motor.

먼저, 본 발명에 의한 도어스위치를 구조를 살펴보기로 한다. 도시된 바와 같이 도어스위치의 케이스(a) 양측에 형성된 홈을 통하여 도면상으로 좌측에는 냉동실용 누름버튼(10)이, 우측에는 냉장실용 누름버튼(10′)이 위치한다. 상기 누름버튼(10,10′) 내부에는 코일스프링(10a)이 탄지되어 있어 냉동, 냉장실도어가 닫혔을 때에는 상기 누름버튼(10,10′)이 눌러진 상태가 되나, 각 도어를 열게되면 상기 누름버튼(10,10′)은 코일스프링(10a)의 탄성에 의해 위로 돌출된다.First, the structure of the door switch according to the present invention will be described. As shown in the drawing through the grooves formed on both sides of the case (a) of the door switch, a freezer compartment push button 10 is located on the left side, and a refrigerator compartment pushbutton 10 'is positioned on the right side. The coil springs 10a are held in the push buttons 10 and 10 'so that the push buttons 10 and 10' are pressed when the freezing and refrigerating chamber doors are closed. The push buttons 10 and 10 'protrude upward by the elasticity of the coil spring 10a.

그리고, 상기 각 누름버튼(10,10′)의 일측에는 지지편(12,12′)이 서로 마주보며 대칭적으로 형성되어 있다. 한편, 상기 지지편(12,12′)은 선단부와 그 옆의 일측에 돌기(12a,12b,12a′,12b′)가 도어스위치 내부를 향하여 형성된다. 상기 돌기중 지지편(12,12′)의 선단부에 형성된 제1돌기(12a,12a′)는 후술하는 팬모터가동편(50)의 작동을 조절하게 되고, 제2돌기(12b,12b′)는 후술하는 램프가동편(60,70)의 작동을 조절하게 된다.And, on one side of each push button (10, 10 '), support pieces (12, 12') are formed symmetrically facing each other. On the other hand, the support pieces (12, 12 ') are formed at the tip and one side of the projection (12a, 12b, 12a', 12b ') toward the inside of the door switch. The first protrusions 12a and 12a 'formed at the front end portions of the support pieces 12 and 12' of the protrusions control the operation of the fan motor movable piece 50, which will be described later, and the second protrusions 12b and 12b '. Will adjust the operation of the lamp movable piece (60, 70) to be described later.

다음, 도어스위치에 전원을 공급하는 제1전원입력단자(30)와 제2전원입력단자(40)가 도어스위치내에 각각 형성되며, 상기 제1전원입력단자(30)는 도어스위치의 중앙에 위치하고 회로분리용 격벽(20)으로 둘러쌓여 제2전원입력단자(40)와 전기적으로 분리된 구조를 이루고 있다. 상기와 같이 제1전원입력단자(30)와 제2전원입력단자(40)가 격벽(20)으로 분리되어 각자 독립적으로 전원을 공급 받을 수 있어 각 단자로 AC(교류) 또는 DC(직류)의 어느것이든지 하나의 도어스위치내에 공급가능하게 된다.Next, a first power input terminal 30 and a second power input terminal 40 for supplying power to the door switch are respectively formed in the door switch, and the first power input terminal 30 is located at the center of the door switch. Surrounded by the circuit separation partition wall 20 to form a structure electrically separated from the second power input terminal (40). As described above, the first power input terminal 30 and the second power input terminal 40 are separated by the partition wall 20 so that they can be supplied with power independently, so that each terminal has an AC (AC) or DC (DC) Either one can be supplied in one door switch.

즉, 제1전원입력단자(30)와 제2전원입력단자(40)는 격벽(20)에 의해 회로적으로 분리되어 독립적으로 각각 전원을 공급받아 하나의 도어스위치내로 공급하게 되므로 제1전원입력단자(30)에는 DC(직류)를 공급하고, 제2전원입력단자(40)에는 AC(교류)를 공급할 수도 있으며, 상기의 경우와 반대의 구성을 이룰 수도 있을 것이다.That is, the first power input terminal 30 and the second power input terminal 40 are separated into circuits by the partition wall 20 and are independently supplied with power and are supplied into one door switch. DC (direct current) may be supplied to the terminal 30, and AC (alternating current) may be supplied to the second power supply input terminal 40, and a configuration opposite to the above case may be achieved.

그리고, 제1전원입력단자(30)의 선단에는 접촉부(30a)를 형성하여 후술하는 팬모터가동편(50)이 상기 접촉부(30a)와 접촉됨에 따라 전원공급을 받게 되어 팬모터(M)의 구동을 조절하게 된다. 한편, 제2전원입력단자(40)는 제1전원입력단자(30)를 감싸는 격벽(20)의 상부에서 양측으로 분리되어 격벽(20)의 양측에 각각 접촉부(40a,40a′)가 형성되어 후술하는 냉동, 냉장실용 램프가동편(60,70)이 상기 접촉부(40a,40a′)와의 접촉여하에 따라 램프(FL,RL)의 작동을 위한 전원공급을 받게된다.Then, the contact portion 30a is formed at the front end of the first power input terminal 30 so that the fan motor movable piece 50, which will be described later, is brought into contact with the contact portion 30a to be supplied with power to the fan motor M. It will regulate the drive. On the other hand, the second power input terminal 40 is separated from both sides of the upper portion of the partition wall 20 surrounding the first power input terminal 30 so that the contact portions 40a and 40a 'are formed on both sides of the partition wall 20, respectively. Lamp moving pieces 60 and 70 for freezing and refrigerating chambers to be described later are supplied with power for the operation of the lamps FL and RL according to contact with the contact portions 40a and 40a '.

한편, 도어스위치 중앙에 형성된 격벽(20)내에는 팬모터(M)와 연결된 팬모터가동편(50)이 위치한다. 상기 팬모터가동편(50)은 탄성력을 가진 판상스프링의 형태로 이루어지고 선단에 접촉점(50a)이 형성된 구조를 이루고 있다.Meanwhile, the fan motor movable piece 50 connected to the fan motor M is located in the partition wall 20 formed at the center of the door switch. The fan motor movable piece 50 is formed in the form of a plate-like spring having an elastic force and forms a structure in which a contact point 50a is formed at the tip.

상기 팬모터가동편(50)은 냉동, 냉장실 누름버튼(10,10′)의 지지편(12,12′)선단에 형성된 제1돌기(12a,12a′)에 의해 작동되는데, 예를들어 제5도에 도시된 바와 같이 상기 누름버튼(10)이 눌러지지 않은 상태에서는 제1돌기(12a)가 팬모터가동편(50)을 내부로 밀게되고 이에 따라 팬모터가동편(50)의 접촉점(50a)은 제1전원입력단자(30)의 접촉부(30a)와 떨어진 상태가 되어 팬모터가동편(50)과 연결된 팬모터(M)에는 전원이 공급되지 않는다.The fan motor movable piece 50 is operated by the first protrusions 12a and 12a 'formed at the tip of the support pieces 12 and 12' of the freezing and refrigerating chamber push buttons 10 and 10 ', for example, As shown in FIG. 5, in the state in which the push button 10 is not pressed, the first protrusion 12a pushes the fan motor moving piece 50 inwardly, and thus the contact point of the fan motor moving piece 50 ( 50a) is separated from the contact portion 30a of the first power input terminal 30 so that power is not supplied to the fan motor M connected to the fan motor movable piece 50.

한편, 상기 냉동, 냉장실용 누름버튼(10,10′)이 둘다 눌러진 상태에서는 누름버튼(10,10′)이 하부로 이동됨에 따라 지지편(12,12′)의 제1돌기(12a,12a′)가 팬모터가동편(50)을 누르지 못하게 되어 팬모터가동편(50)은 자체 탄성에 의해 원상회복된다. 이에따라 팬모터가동편(50)의 선단에 형성된 접촉점(50a)이 제1전원입력단자(30)의 접촉부(30a)에 접촉되어 팬모터가동편(50)에 전류가 공급된다. 그리고, 상기 누름버튼(10,10′)중 어느 하나가 눌러진 상태, 예를들면 냉동실용누름버튼(10)만 눌러진 상태에서는 눌러지지않은 냉장실용 누름버튼(10′)의 제1돌기(12a′)에 의해 상기 팬모터가동편(50)은 내부로 눌러진 상태가 되어 제1전원입력단자(30)의 접촉부(30a)와 팬모터가동편(50)의 접촉점(50a)이 서로 떨어지게 되어 팬모터가동편(50)으로 전원공급이 되지 않는다.On the other hand, in the state in which both the push buttons 10 and 10 'for the freezer and refrigerator compartment are pressed, the first protrusions 12a and 12a of the support pieces 12 and 12' are moved as the push buttons 10 and 10 'are moved downward. 12a ') is unable to press the fan motor moving piece 50, the fan motor moving piece 50 is restored to its original shape by its elasticity. Accordingly, the contact point 50a formed at the tip of the fan motor movable piece 50 contacts the contact portion 30a of the first power input terminal 30 so that a current is supplied to the fan motor movable piece 50. Then, any one of the push buttons (10, 10 ') is pressed, for example, the first projection of the refrigerating room push button (10') that is not pressed in a state in which only the push button 10 for the freezer compartment is pressed ( 12a '), the fan motor moving piece 50 is pressed inward so that the contact portion 30a of the first power input terminal 30 and the contact point 50a of the fan motor moving piece 50 are separated from each other. Fan power is not supplied to the moving piece (50).

다음, 상기 팬모터가동편(50)과 제1전원입력단자(30)를 감싸는 격벽(20)의 좌,우측에는 램프가동편(60,70)이 각각 설치되며, 도면상으로 좌측에는 냉동실용 누름버튼(10)에 의해 작동되는 냉동실 램프가동편(60)이 위치하고 우측에는 냉장실용 누름버튼(10′)에 의해 작동되는 냉장실 램프가동편(70)이 위치한다.Next, lamp moving pieces 60 and 70 are installed on the left and right sides of the partition wall 20 surrounding the fan motor moving piece 50 and the first power input terminal 30, respectively. The freezer compartment lamp movable piece 60 operated by the push button 10 is located, and the refrigerating compartment lamp movable piece 70 operated by the refrigerator button pusher 10 'is located on the right side.

상기 각 램프가동편(60,70)은 탄성을 가진 판상스프링 형태로 이루어지고, 상기 램프가동편(60,70)의 선단에는 램프가동편 접촉점(60a,70a)이 형성되며 또한 램프가동편(60,70)의 정면 일측에 절곡되어 돌출된 접촉돌기(60b,70b)가 형성된다. 상기 각 누름버튼(10, 10′)의 지지편(12,12′)에 형성된 제2돌기(12b,12b′)가 상기 접촉돌기(60b,70b)에 접촉되어 램프가동편(60,70)을 유동시킴에 따라 선단의 램프가동편접촉점(60a,70a)이 상술한 제2전원입력단자(40)의 접촉부(40a,40a′)와의 접촉에 의해 전원공급을 받게된다. 즉, 제6도에 도시된 바와 같이 냉동실용 누름버튼(10)이 눌러지지않은 상태에서는 지지편(12)의 제2돌기(12b)가 램프가동편(60)의 접촉돌기(60b)에 접촉되어 냉동실 램프가동편(60)을 내부로 밀게되고 이에 따라 냉동실 램프가동편(60)의 선단에 형성된 접촉점(60a)이 제2전원입력단자(40)의 좌측접촉부(40a)와 접촉되어 냉동실 램프가동편(60)에 전원이 공급되고, 누름버튼(10)이 눌러진 상태에서는 지지편(12)의 제2돌기(12b)가 하부로 밀려남에 따라 상기 제2돌기(12b)가 접촉돌기(60b)와 떨어지게 되고 이에따라 냉동실 램프가동편(60)이 탄성회복되어 램프가동편(60) 접촉점(60a)이 제2전원입력단자(40)의 접촉부(40a)와 떨어지게 되어 전원공급이 중단된다.Each of the lamp movable pieces 60 and 70 is formed in a plate-like spring with elasticity, and the lamp movable piece contact points 60a and 70a are formed at the ends of the lamp movable pieces 60 and 70 and the lamp movable pieces ( The contact protrusions 60b and 70b which are bent and protruded on one side of the front surface of the 60 and 70 are formed. The second projections 12b and 12b 'formed on the support pieces 12 and 12' of the push buttons 10 and 10 'are in contact with the contact projections 60b and 70b to allow the lamp movable pieces 60 and 70 to be contacted. As a result, the lamp movable piece contact points 60a and 70a at the front end are supplied with power by contacting the contact portions 40a and 40a 'of the second power input terminal 40 described above. That is, as shown in FIG. 6, when the freezer compartment push button 10 is not pressed, the second protrusion 12b of the support piece 12 contacts the contact protrusion 60b of the lamp movable piece 60. As a result, the freezer compartment lamp movable piece 60 is pushed inward, and thus the contact point 60a formed at the tip of the freezer compartment lamp movable piece 60 is in contact with the left contact portion 40a of the second power input terminal 40, thereby freezing the lamp. When the power is supplied to the movable piece 60 and the push button 10 is pressed, the second protrusion 12b of the support piece 12 is pushed downward so that the second protrusion 12b is brought into contact with each other. 60b) and thus the freezer compartment lamp movable piece 60 is elastically recovered so that the contact point 60a of the lamp movable piece 60 is separated from the contact portion 40a of the second power input terminal 40, so that the power supply is stopped.

다음은 상기와 같은 구조로 이루어진 냉장고용 도어스위치에 의하여 램프(FL, RL) 및 팬모터(M)가 작동되는 과정을 제6도와 제7도를 참조하여 설명하기로 한다.Next, a process of operating the lamps FL and RL and the fan motor M by the door switch for a refrigerator having the above structure will be described with reference to FIGS. 6 and 7.

제6도는 제3도의 B-B선 단면도로서, (a)도는 도어스위치가 눌러지지 않은 상태를 나타낸 도이고, (b)도는 도어스위치가 눌러진 상태를 나타낸 도이다. 제7도는 제3도의 C-C선 단면도로서, (a)도는 도어스위치가 눌러지지 않은 상태를 나타낸 도이고, (b)도는 도어스위치가 눌러진 상태를 나타낸 도이다.6 is a cross-sectional view taken along line B-B of FIG. 3, (a) is a view showing a state in which the door switch is not pressed, and (b) is a view showing a state in which the door switch is pressed. 7 is a cross-sectional view taken along the line C-C of FIG. 3, (a) is a view showing a state that the door switch is not pressed, (b) is a view showing a state that the door switch is pressed.

냉장실 또는 냉동실도어가 열리게 되면 냉장실램프(RL) 또는 냉동실램프(FL)가 작동되어 냉장, 냉동실내에 불이 들어오고 이때 팬모터(M)는 가동이 중지된다. 이와는 달리 각 도어가 닫혔을 때 램프(FL, RL)는 작동되지 않고 팬모터(M)만 작동된다.When the refrigerating compartment or the freezer door is opened, the refrigerating compartment lamp RL or the freezing compartment lamp FL is activated to light in the refrigerating and freezing compartment, and the fan motor M is stopped. On the contrary, when each door is closed, the lamps FL and RL are not operated but only the fan motor M is operated.

상기 램프(FL, RL) 및 팬모터(M)의 작동을 도어스위치와 관련하여 설명하면, 먼저 냉동실 도어만 열렸을 경우(즉, 상기 냉동실용 누름버튼(10)은 눌러지지 않은 상태이고, 냉장실용 누름버튼(10′)은 눌러진 상태), 냉동실용 누름버튼(10)의 지지편(12)은 상부에 위치하며 냉장실용 누름버튼(10′)의 지지편(12′)은 하부에 위치하게 된다.Referring to the operation of the lamp (FL, RL) and the fan motor (M) with respect to the door switch, first when only the freezer door is opened (that is, the freezer push button 10 is not pressed, the refrigerator compartment for The push button 10 'is pressed), the support piece 12 of the freezer push button 10 is located at the top, and the support piece 12' of the refrigerating compartment push button 10 'is located at the bottom. do.

상기의 경우 냉동실용 누름버튼(10)의 지지편(12) 선단에 위치한 제1돌기(12a)는 팬모터가동편(50)을 누르게 되고, 이에따라 팬모터가동편(50)의 접촉점(50a)은 제1전원입력단자(30)의 접촉부(30a)와 떨어지게 되어 팬모터가동편(50)으로 전원공급이 중단되어 팬모터(M)는 작동되지 않는다. 이때 제2돌기(12b)는 냉동실용 램프가동편(60)의 접촉돌기(60b)와 접촉되어 램프가동편(60)을 내부로 밀게되어 냉동실용 램프가동편(60)의 접촉점(60a)은 제2전원입력단자(40)의 접촉부(40a)와 접촉되어 냉동실 램프(FL)가 작동된다.In the above case, the first protrusion 12a located at the tip of the support piece 12 of the freezer push button 10 presses the fan motor moving piece 50, and thus the contact point 50a of the fan motor moving piece 50. Is separated from the contact portion 30a of the first power input terminal 30 so that the power supply to the fan motor moving piece 50 is stopped, so that the fan motor M is not operated. At this time, the second projection 12b is in contact with the contact projection 60b of the lamp moving piece 60 for the freezing chamber and pushes the lamp moving piece 60 therein, so that the contact point 60a of the lamp moving piece 60 for the freezer compartment is The freezer compartment lamp FL is operated in contact with the contact portion 40a of the second power input terminal 40.

한편, 냉장실용 램프가동편(70)은 냉장실용 누름버튼(10′)의 지지편(12′)이 하부에 위치함에 따라 제2돌기(12b)가 램프가동편(70)의 접촉돌기(70b)와 접촉되지 않아 냉장실용램프가동편(70)을 내부로 밀지 못하여 램프가동편(70)의 접촉점(70a)이 제2전원입력단자(40)의 접촉부(40a)와 떨어져 위치하여 전원공급이 되지 않으므로 냉장실 램프(RL)는 작동되지 않는다.On the other hand, in the refrigerating chamber lamp movable piece 70, as the support piece 12 'of the refrigerating compartment push button 10' is located at the lower portion, the second protrusion 12b is the contact protrusion 70b of the lamp movable piece 70. ), The contact point 70a of the lamp movable piece 70 is located away from the contact portion 40a of the second power input terminal 40 because the lamp movable piece 70 for the refrigerating compartment cannot be pushed inward. The refrigerator compartment lamp RL is not activated.

다음, 냉장실도어만 열었을 경우(즉, 냉동실용 누름버튼(10)은 눌러진 상태이며, 냉장실용 누름버튼(10′)은 눌러지지 않은 상태), 상기의 경우에는 눌러지지 않은 냉장실용 누름버튼(10′)의 제1돌기(12a′)가 팬모터가동편(50)을 내부로 누르게 되어 팬모터가동편(50)의 접촉점(50a)이 제1전원입력단자(30)의 접촉부(30a)와 떨어져 전원공급이 중단되어 팬모터(M)는 구동하지 않게되며, 제2돌기(12′)가 냉장실용 램프가동편(70)의 접촉돌기(70b)와 접촉되어 냉장실용램프가동편(70)을 내부로 밀게되어 램프가동편(70)의 접촉점(70a)이 제2전원입력단자(40)의 접촉부(40a)에 접촉되어 전원이 인가되어 냉장실 램프(RL)는 작동된다.Next, when only the refrigerating compartment door is opened (that is, the freezer push button 10 is in a depressed state, and the refrigerating compartment push button 10 'is not pressed), and in this case, the refrigerating compartment push button ( The first projection 12a 'of 10' presses the fan motor moving piece 50 inwardly such that the contact point 50a of the fan motor moving piece 50 is the contact portion 30a of the first power input terminal 30. And the power supply is stopped so that the fan motor M is not driven, and the second projection 12 'is brought into contact with the contact projection 70b of the lamp moving piece 70 for the refrigerating compartment to allow the lamp moving piece 70 for the refrigerating compartment. ) Is pushed inward so that the contact point 70a of the lamp movable piece 70 contacts the contact portion 40a of the second power input terminal 40 so that power is applied to the refrigerator compartment lamp RL.

그러나 냉동실용 누름버튼(10)의 지지편(12)이 하부에 위치함에 따라 제2돌기(12b)가 냉동실용 램프가동편(60)을 내부로 밀지 못함에 따라 램프가동편(60)에 전원이 공급되지 않아 냉동실 램프(FL)는 작동되지 않는다.However, as the support piece 12 of the freezer compartment push button 10 is located at the bottom, the second protrusion 12b does not push the lamp movable piece 60 for the freezer compartment into the power supply to the lamp movable piece 60. The freezer lamp FL is not activated because it is not supplied.

다음, 냉동, 냉장실도어가 둘다 닫혔을 경우(즉, 냉동, 냉장실용 누름버튼(10,10′)이 둘다 눌러진 상태), 이때에는 각 누름버튼(10,10′)의 지지편(12,12′)이 둘다 하부로 밀려난 상태가 되며 이에 따라 각 지지편(12,12′)의 제1돌기(12a,12a′)는 팬모터가동편(50)을 내부로 밀지 못하게 되어 팬모터가동편(50)의 접촉점(50a)은 제1전원입력단자(30)의 접촉부(30a)에 접촉하여 제1전원입력단자(30)에 의해 공급된 전원이 팬모터가동편(50)으로 전달되어 팬모터(M)가 작동된다. 한편, 각 지지편(12,12′)의 제2돌기(12b,12b′)는 램프가동편(60,70)의 각 접촉돌기(60b,70b)와 접촉되지 않아 각 램프가동편(60,70)을 내부로 밀지 못하여 각 램프가동편(60,70)은 제2전원입력단자(40)와 떨어져 전원공급이 되지않아 램프(FL,RL)는 작동되지 않는다.Next, when both the freezing and refrigerating chamber doors are closed (that is, when the freezing and refrigerating chamber push buttons 10 and 10 'are both pressed), the support piece 12 of each push button 10 and 10' is then pressed. 12 ') are both pushed downward, and thus, the first projections 12a and 12a' of each support piece 12 and 12 'do not push the fan motor moving piece 50 to the inside. The contact point 50a of the copper piece 50 contacts the contact part 30a of the first power input terminal 30 so that the power supplied by the first power input terminal 30 is transmitted to the fan motor movable piece 50. The fan motor (M) is activated. On the other hand, the second projections 12b and 12b 'of each of the support pieces 12 and 12' are not in contact with each of the contact projections 60b and 70b of the lamp movable pieces 60 and 70, so that the respective lamp movable pieces 60, Since the lamp movable pieces 60 and 70 are separated from the second power input terminal 40 and are not supplied with power, the lamps FL and RL are not operated.

상기의 설명과 같이 제1전원입력단자(30)와 제2전원입력단자(40)가 내부 격벽에 의해 전기적으로 분리되어 구성됨으로서, 냉동, 냉장실 램프(FL, RL)는 AC(교류)를 사용하고, 팬모터(M)는 DC(직류)를 사용하는 회로를 구성할 수도 있으며, 상기와는 반대로 냉동, 냉장실 램프(FL, RL)는 DC(직류)를 이용하며, 팬모터(M)는 AC(교류)를 이용할 수도 있을 것이다. 또한 제1전원입력단자(30)와 제2전원입력단자(40)에 동일하게 AC(교류)나 또는 DC(직류)를 양단자에 공급할 수도 있을 것이다.As described above, since the first power input terminal 30 and the second power input terminal 40 are electrically separated by an internal partition, the freezer and refrigerator compartment lamps FL and RL use AC (AC). In addition, the fan motor M may constitute a circuit using DC (direct current). In contrast to the above, the freezer and refrigerator compartment lamps (FL, RL) use DC (direct current), and the fan motor (M) AC may be used. In addition, AC (AC) or DC (DC) may be supplied to both terminals in the same manner to the first power input terminal 30 and the second power input terminal 40.

이상에서 설명한 본 발명에 의한 냉장고 도어스위치에서는 다음과 같은 잇점이 있다.The refrigerator door switch according to the present invention described above has the following advantages.

내부 격벽에 의해 회로적으로 분리되는 두 개의 전원입력단자가 하나의 도어스위치내에 공급되므로 하나의 도어스위치로 AC(교류)와 DC(직류)를 혼용해 사용할 수 있는 잇점이 있다.Since two power input terminals that are separated by internal partitions are supplied in one door switch, there is an advantage in that AC (AC) and DC (DC) can be used in combination with one door switch.
