본 고안은 냉장고의 도어스위치 장치에 관한 것으로 특히 도어의 개폐에 따라 고내의 팬모터 및 램프를 기구적으로 절환동작시키도록한 냉장고의 도어 스위치 장치에 관한 것이다.The present invention relates to a door switch device of the refrigerator, and more particularly to a door switch device of the refrigerator to mechanically switch the fan motor and lamp in the refrigerator according to the opening and closing of the door.

종래의 냉장고에 있어 도어의 개폐에 따라 고내의 팬 모터 및 램프를 동작시키기 위한 기구적 구성은 제 1 도에서 보는 바와 같이 냉동실 도어의 개폐에 의해 눌려지는 누름버튼(1)과 냉장실도어의 개폐에 의해 눌려지는 누름버튼(2)이 하측의 스프링(5) (6)에 의해 탄동되도록 설치되어 있고 상기 누름버튼(1) (2)의 각 일측에는 구동볼(3) (4)이 설치되어 있어 누름버튼(1) (2)의 상, 하 이동에 따라 접속단자(11)에 의해 접속된 가동편(7) (8)이 좌, 우 이동되어 전원공급단자(12)와 단자 (13) (14)를 절환접촉시키도록 구성하고, 상기 단자(13) (14)에는 제 2 도의 회로도에서 보는 바와 같이 팬모터(F, M)와 램프(L)가 각각 접속되어 있는 구성으로, 이의 동작상태를 도면에 따라 설명하면 다음과 같다.In the conventional refrigerator, the mechanical configuration for operating the fan motor and the lamp in the refrigerator according to the opening and closing of the door is shown in FIG. 1 to the opening and closing of the push button 1 and the refrigerating chamber door which are pressed by opening and closing the freezer door. The push button 2 pressed by the lower spring (5) and 6 is installed so that it is elastic, and each one side of the push button (1) (2) is provided with driving balls (3) (4) As the pushbuttons (1) and (2) move up and down, the movable pieces (7) (8) connected by the connecting terminal (11) are moved left and right, so that the power supply terminal (12) and the terminal (13) ( 14) is configured to be in contact with the switch, and the fan motors F and M and the lamps L are connected to the terminals 13 and 14, respectively, as shown in the circuit diagram of FIG. When described according to the drawings as follows.

제 1 도는 누름버튼(1) (2)을 모두 누르지 않은 상태를 나타낸 것으로 전원은 전원공급단자(12)를 통해 인가되게 된다.1 illustrates a state in which the push buttons 1 and 2 are not all pressed, and power is applied through the power supply terminal 12.

먼저 상기 누름버튼(1)을 누르지 않았을때, 즉 냉동실 도어를 열었을때에는 전원 공급단자(12)로 인가되는 전원은 차단되어 스위치 회로내에 인가되지 않게 되고, 누름버튼(1)을 누르고 누름버튼(2)을 누르지 않았을때, 즉 냉동실 도어를 닫고 냉장실 도어를 열었을때에는 누름버튼(1)의 구동볼(3)이 시이소오(see saw)동작을 하는 가압편(9)의 상면에서 하측으로 이동되어 가압편(9)의 하부를 밀어주게 되므로 가동편(7)은 전원 공급단자(12)와 접촉되어 전원이 상기 가동편(7)과 접속단자(11) 그리고 가동편(8)을 순차거쳐 램프(L)와 연결된 단자(14)에 인가되어 고내의 램프(L)를 점등시키게 된다.First, when the push button 1 is not pressed, that is, when the freezer door is opened, the power applied to the power supply terminal 12 is cut off so that it is not applied to the switch circuit, and the push button 1 is pressed and the push button 2 is pressed. ), When the freezer door is closed and the refrigerating door is opened, the driving ball 3 of the push button 1 is moved downward from the upper surface of the pressing piece 9 which performs the saw sawing operation. Since the lower part of the piece 9 is pushed, the movable piece 7 is brought into contact with the power supply terminal 12 so that the power source sequentially passes through the movable piece 7, the connecting terminal 11, and the movable piece 8. It is applied to the terminal 14 connected to L) to turn on the lamp (L) in the interior.

그리고 누름버튼(1) (2)을 모두 눌렀을 경우에는 냉동실 및 냉장실 도어가 모두 닫힌 상태이므로, 이때에는 가동편(7) (8)이 전원공급단자(12)와 팬모터(F.M)가 연결된 단자(13)에 각각 접촉되어 전원이 가동편(7)과 접속단자(11) 그리고 가동편(8)을 거쳐 단자(13)에 인가되므로 팬모터(F.M)를 구동시키게 된다.When the pushbuttons (1) and (2) are all pressed, both the freezer compartment and the refrigerator compartment door are closed. At this time, the movable pieces (7) (8) are connected to the power supply terminal (12) and the fan motor (FM). In contact with each of 13, power is applied to the terminal 13 via the movable piece 7, the connection terminal 11, and the movable piece 8, thereby driving the fan motor FM.

그러나 상기와 같은 종래 기술의 동작에서 누름버튼(1)을 누르지 않을 경우(냉동실 도어를 열었을 경우)전원은 전원공급단자(12)로 부터 차단되므로 냉동실 및 냉장실 도어를 모두 열었을 경우 누름버튼(1) (2)을 모두 누르지 않았을 경우 고내의 램프(L)가 점등되지 않아 야간에 냉동 및 냉장실 도어를 모두 열어 놓고 식품을 넣거나 꺼낼 경우 매우 불편할 뿐만 아니라, 그의 기구적 구성요소가 많아 조립성이 저하되며 계속적인 반복동작시 구동볼이 이탈되어 정확한 동작이 이루어지지 않는 문제점이 있었다.However, when the push button 1 is not pressed in the operation of the prior art as described above (when the refrigerator compartment door is opened), the power is cut off from the power supply terminal 12, so when the freezer compartment and the refrigerator compartment door are opened, the push button 1 If you do not press (2), the lamp (L) inside the refrigerator does not light up, so it is very inconvenient to put food in or take out the food in the freezer and refrigerating compartment doors at night, and the assembly is deteriorated due to the large number of mechanical components. There was a problem that the drive ball is separated during the continuous repetitive operation is not performed correctly.

이에 본 고안은 상기한 문제점을 개선시키기 위해 안출된 것으로써 단순구성물의 캠(cam)을 이용하여 누름버튼의 상, 하 이동에 따라 탄성력을 갖는 가동편이 이동되어 고내의 램프 및 팬모터를 절환 동작시키도록 한 것으로, 이하 그 기술구성을 첨부된 도면에 따라 설명하면 다음과 같다.Therefore, the present invention was devised to improve the above problems, and the movable piece having elastic force is moved according to the up and down movement of the push button by using a cam of a simple configuration to switch the lamp and the fan motor in the refrigerator. The technical configuration will be described below with reference to the accompanying drawings.

제 3 도는 본 고안에 따라 구성된 냉장고 도어스위치 장치를 나타낸 것으로, 케이스(17)의 상측으로 돌출된 냉동실용 누름버튼(1')과 냉동실용 누름버튼(2')의 하측이 케이스(17) 내부에서 각각의 스프링(5) (6)에 의해 탄지되며, 상기 누름버튼(1') (2')의 하단부 일측에는 캠(15) (16)을 각각 설치하여 캠(15) (16)의 사이에 전원 공급단자(12')가 탄성력을 갖는 가동편(8')과 스롯용접되어 가동편(8')의 선단이 제 4 도의 팬모터(F, M)와 연결된 단자(14')와 접촉되도록 설치하고, 상기 가동편(8')의 일측에는 접속단자(11')를 근접 설치하여 접속단자(11')의 선단이 가동편(7')과 스폿용접으로 고정되어 캠(15)의 일측과 맞닿으며 가동편(7')의 하단부에는 제 4 도의 램프(L)와 연결된 단자(13')에 근접설치되도록 한 구성으로, 이하 그 기술구성의 동작 상태 및 작용효과를 도면에 따라 설명하면 다음과 같다.3 shows a refrigerator door switch device constructed according to the present invention, and a lower side of a freezer compartment push button 1 'and a freezer compartment push button 2' protruding to an upper side of the case 17 are inside the case 17. At each of the spring (5) (6) is supported by, the lower end of the push button (1 ') (2') of the cam 15, 16, respectively installed between the cam (15, 16) The power supply terminal 12 'is slot welded to the movable piece 8' having elastic force so that the tip of the movable piece 8 'contacts the terminal 14' connected to the fan motors F and M of FIG.

Explain as follows.

먼저 제 3 도에 실선의 표기는 누름버튼(1') (2')을 누르지 않은 상태이고 점선의 표기는 누름버튼(1') (2')을 누른 상태를 나타낸 것이다.First, in FIG. 3, the notation of the solid line indicates that the push buttons 1 'and 2' have not been pressed, and the notation of the dotted line shows the state of pressing the push buttons 1 'and 2'.

전원은 전원공급단자(12)로 입력되며 냉장실용 누름버튼(2')을 누르지 않았을 경우 또는 누름버튼(1') (2')을 모두 누르지 않았을 경우(즉, 냉장실 도어를 열었을 경우나 냉장실 및 냉동실 도어를 모두 열었을 경우)에는 제 3 도의 실선 표기와 같이 가동편(2')의 접점과 단자(14')의 접점이 접촉되어 있으므로 전원공급단자(12')의 전원은 상기 가동편(8')과 단자(14')로 통전되어 고내의 램프(L)를 점등시키고, 누름버튼(1') (2')을 모두 눌렀을 경우 (즉, 냉동실 및 냉장실 도어를 모두 닫았을 경우)에는 누름버튼(1') (2')의 하단부가 하방향으로 눌러지면서 각각의 캠(15) (16)을 밀어 점선으로 표기된 것과 같이 가동편(7')의 접점이 단자(13')의 접점에 접촉되며 가동편(8')의 접점은 단자(14')와 떨어져 접속단자(11')의 접점에 접촉되어 전원 공급단자(12')의 전원이 가동편(8')과 접속단자(11') 및 가동편(7')을 순차거쳐 단자(13')로 통전되므로 팬모터(F.M)를 구동시키게 된다.The power is input to the power supply terminal 12 and when the refrigerator push buttons 2 'are not pressed or when the push buttons 1' 2 'are not pressed (i.e. when the refrigerator door is opened or the refrigerator compartment and When all the freezer doors are opened), the contacts of the movable pieces 2 'and the contacts of the terminals 14' are in contact with each other, as shown in the solid line in FIG. 3, so that the power supply of the power supply terminal 12 ' ')' And the terminal 14 'are energized to turn on the lamp L in the interior, and when the pushbuttons 1' and 2 'are all pressed (i.e. when both the freezer and refrigerator doors are closed) As the lower end of the button (1 ') (2') is pushed downward, the respective contacts of the movable piece (7 ') are pushed to the contacts of the terminal (13') as shown by the dashed lines by pushing the respective cams (15) and (16). The contact of the movable piece 8 'is separated from the terminal 14' and is brought into contact with the contact of the connecting terminal 11 'so that the power supply of the power supply terminal 12' is connected to the movable piece 8 '. ) And the connecting terminal 11 'and the movable piece 7' are sequentially energized to the terminal 13 ', thereby driving the fan motor F.M.

또한 상기 누름버튼(1') (2')중 어느 하나라도 누르지 않았을 경우(즉, 냉동실 및 냉장실 도어중 어느 하나라도 열렸을 경우)에는 램프(L)를 점등시킬수는 있으나 접속단자(11')로 부터 전원이 차단되므로 팬모터(F.M)는 구동되지 않게 된다.In addition, when one of the push buttons 1 'and 2' is not pressed (that is, when any of the freezer compartment and the refrigerating compartment door is opened), the lamp L may be turned on, but the connection terminal 11 ' Since the power is cut off, the fan motor (FM) is not driven.

따라서, 본 고안에 따른 냉장고 도어스위치 장치는 이상의 설명에서와 같이 단순구조물의 캠을 이용하여 간단하게 구성시킴으로 조립성이 양호하며 동작 요소가 적어 고장 발생이 적을 뿐만 아니라 냉장고에 실적용하여 사용할 경우 냉동실 및 냉장실 도어를 모두 열어 놓은 상태에서도 고내의 램프가 점등되도록 되어 있어 야간에 사용의 불편을 방지시키는 효과를 갖게 된다.Therefore, the refrigerator door switch device according to the present invention is easy to assemble by using a simple structure of the cam as described above, good assembly, and less operating elements, less failure occurs as well as freezer and when used for performance in the refrigerator The lamp inside the refrigerator is turned on even when all the refrigerating chamber doors are opened, thereby preventing the inconvenience of use at night.
