본 고안은 동체내에 격벽을 형성하여 접편작동부를 밀폐시키고 돌출된 단자부는 하향되게 설치시켜 외부와는 완전히 폐쇄되게하여 먼지나 습기가 스위치내부로 침입하는 것을 방지케한 냉장고용 개량도어스위치에 관한 것이다.The present invention relates to an improved door switch for a refrigerator which forms a partition in the fuselage to seal the folding operation part and the protruding terminal part is installed downward so as to be completely closed from the outside to prevent dust or moisture from entering the switch. will be.

종래 냉장고용 도어스위치는 실개소 제57-163628호와 같이 스위치 동체가 단일구조로 되어 있어 누름보턴의 작동공을 통하여 동체내부에 먼지나 습기의 유입이 용이하게 이루어지게 되므로 접점 및 단자동작부가 쉽게 손상되고 접점부위에 고형물질이 생성되면서 동작불능현상과 전로 현상 등과 같은 전기적 현상이 발생하는 등 많은 폐단이 있었다.Conventional door switch for refrigerator has a single switch body as shown in the actual location 57-163628, so that dust and moisture can be easily introduced into the body through the operation of the push button, so that the contact and the terminal operation part is easily There have been many closures such as damage and the formation of solid materials at the contact points, causing electrical phenomena such as inoperability and converters.

본 고안은 이와 같은 종래의 냉장고용 도어스위치의 폐단을 해소코자 안출된 것으로서 접편작동부와 단자부가 누름보턴과 격리되게 형성하여 외부로부터 습기나 먼지등과 같은 이물질의 침입을 막아 도어스위치가 항상 제기능을 발휘하게 하고 전기적인 접촉 불량이나 전로현상을 미연에 방지하려는데 그 목적이 있는 것이다.The present invention is designed to solve the closed end of the conventional door switch for the refrigerator, and the folding operation part and the terminal part are formed to be isolated from the push button to prevent the intrusion of foreign substances such as moisture or dust from the outside, so that the door switch is always removed. Its purpose is to make it work and to prevent electrical contact failures and converter phenomena in advance.

이와 같은 목적의 본 고안을 첨부된 도면에 의거 상세히 설명하면 다음과 같다.The present invention for this purpose will be described in detail with reference to the accompanying drawings.

동체(1) 중앙부에 격벽(2)을 형성하여 이 격벽 일측면에 접편작동부(20)를 형성하여 고정접점(3)(3')을 가진 고정접편(4)(4')과 가동접점(3a)(3a')를 가진 가동접편(4a)(4a')을 고정단자(5)(5')(5a)(5a')에 고착하고 가동접편(4a)(4a')의 단부를 가압돌편(6)에 의해 유동하는 슬라이더(7)의 접편삽입홈(8)(8')에 각각 삽입시키며 격벽(2)타측면에 스프링(9)에 의해 탄지된 누름보턴(10)을 가압돌편(6)의 축(11)으로 축설하고 슬라이더(7)에 가압돌편 안내돌부(12) 및 안내홈(13)을 형성하며 누름보턴(10)의 삽입부(14)일측에 돌출단자홈(15)을 형성시켜서 된 것이다.A partition wall 2 is formed at the center of the fuselage 1 to form a contact operation part 20 on one side of the partition wall, and a movable contact 4 and 4 'having a fixed contact 3 and 3' and a movable contact. (3a) (3a '), and fasten the movable pieces 4a and 4a' to the fixed terminals 5, 5 ', 5a and 5a' and the ends of the movable pieces 4a and 4a '. Pressing the push button 10 supported by the spring 9 on the other side of the partition wall 2 is inserted into the folding insertion grooves 8, 8 ′ of the slider 7 flowing by the pressure protrusion piece 6, respectively. It is laid out on the shaft 11 of the projection piece 6 and forms the pressing projection piece 12 and the guide groove 13 in the slider 7, and the protruding terminal groove (one side) of the insertion part 14 of the push button 10 15) was formed.

미설명 부호 16, 16'는 걸림탄편이고 17은 덮개 18은 덮개(17)에 형성된 익편, 19는 냉장고 벽체이다.Reference numerals 16, 16 'are the engaging bullet pieces, 17 is a cover 18 formed on the cover 17, 19 is a refrigerator wall.

이와 같이 구성된 본 고안은 누름보턴(10)이 접점작동부(20)와 격벽(2)을 사이에 두고 축설된 상태이므로 누름보턴(10)의 삽입부(14)를 통하여 먼지나 습기 등이 접편 작동부(20)로 침투할 수 없는 것으로 냉장고에 설치하여 사용할 때 도어를 개방시키면 제3도에 도시된 바와 같이 스프링(9)의 탄지력에 의해 누름보턴(10)이 축(1)을 중심으로 반시계 방향으로 회전이 되어 돌출이 되면서 누름보턴(10)을 축설하고 있는 축(11)도 동시에 회전하여 가압돌편(6)을 축(11)을 중심으로 반시계 방향으로 회전시켜 슬라이더(7)의 안내홈(13)에 가입돌편(6)이 삽입되면서 슬라이더(7)를 상측으로 이송시키며 가동접점(3a)에 접속시켜 고정단자(5)(5')에 연결된 램프(미도시 됨)가 고정단자(5)(5')를 온상태가 되도록 하고, 이때에 가동접점(3a')는 고정접점(3')에서 이격이 되어 고정단자(5a,5a')에 연결된 콤프레샤(미도시되)이 오픈상태가 된다.Since the push button 10 is constructed in such a state that the push button 10 is arranged with the contact operation part 20 and the partition wall 2 interposed therebetween, the dust or moisture may be folded through the insertion part 14 of the push button 10. When the door is opened when the refrigerator is installed and used in the refrigerator as it cannot penetrate into the operating part 20, as shown in FIG. 3, the push button 10 is centered on the shaft 1 by the holding force of the spring 9. Rotate in the counterclockwise direction to protrude and the shaft 11, which is pushing the push button 10, is also rotated at the same time to rotate the pressing piece 6 in the counterclockwise direction about the shaft 11 to the slider (7). Ramp (6) is inserted into the guide groove (13) of the guide) to move the slider (7) upwards and connected to the movable contact (3a) lamp connected to the fixed terminal (5) (5 ') (not shown) The fixed terminals 5 and 5 'are turned on, and at this time, the movable contact 3a' is spaced apart from the fixed contact 3 'and is fixed. The compressor (not shown) connected to the rulers 5a and 5a 'is open.

그리고 도어를 닫으면 누름보턴(10)이 축(11)을 중심으로 하여 시계방향으로 회전하게 되어 스프링(9)을 가압하고 상기 누름보턴(10)을 축설한 축(11)을 시계방향으로 회전시킴으로 가압돌편(6)이 제3b도에서 보는 바와 같이 시계방향으로 회전하여 슬라이더(7)을 끌어내리게 됨으로 접속되어있던 가동접점(3a)는 고정접점(3)로부터 떨어져 램프가 오프상태에서 되고 동시에 가동접점(3a')가 고정접점(3')에 접속됨으로써 고정단자(5a)(5a')가 연결되어 냉장고를 가동시키는 콤푸레셔 등을 가동시키게 되는 것이다.When the door is closed, the push button 10 rotates in a clockwise direction about the shaft 11 to press the spring 9 and rotate the shaft 11 in which the push button 10 has been laid in a clockwise direction. As the pressing piece 6 rotates clockwise to pull down the slider 7 as shown in FIG. 3b, the movable contact 3a, which is connected, is separated from the fixed contact 3, and the lamp is turned off and simultaneously operated. By connecting the contacts 3a 'to the fixed contacts 3', the fixed terminals 5a and 5a 'are connected to operate a compressor or the like for operating the refrigerator.

이와 같이 본 고안은 격벽(2)에 의해 누름보턴(10)과 접편작동부(20)가 완전히 분리되고 접편작동부(20)는 덮개(17)가 초음파 용착됨으로써 기밀이 유지되어 외부로부터 습기나 먼지 등과 같은 이물질이 침투될 수 없으므로 원활한 동작을 영구적으로 지속할 수 있는 효과가 있으며 또 고정단자를 4개로 구성하였으므로 회로배선이 용이하고 오동작이 방지되는 것으로 실용적인 고안인 것이다.Thus, the present invention is the push button 10 and the foldable operating portion 20 is completely separated by the partition (2) and the foldable operating portion 20 is the cover 17 is ultrasonically welded to maintain the airtight and moisture from the outside Since foreign matters such as dust cannot penetrate, there is an effect of permanently maintaining a smooth operation. Also, since four fixed terminals are formed, circuit wiring is easy and malfunction is prevented.
