본 고안은 도어가 완전히 닫혀야만 각 구동부에 전원이 공급되어 전자레인지를 작동시킬 수 있게하는 안전장치인 마이크로 스위치의 개폐장치에 대한 것이다.The present invention relates to an opening and closing device of a micro switch, which is a safety device that can supply power to each drive unit to operate a microwave oven when the door is completely closed.
종래에는 제3도에서 보는 바와같이 도어(27)를 닫으면 이 도어(27)에 착설된 키이(29)가 직접 마이크로스위치(23)의 접점을 눌러주어 스위치(23)가 동작되게한 구조로 되어 있었기 때문에 도어(27)가 닫히는 순간 키이(29)를 당겨주고 있는 스프링(24)의 힘이 직접 스위치(23)의 접점을 눌러주게되는 작용을 하므로 스프링(24)의 힘이 스위치(23)내에 형성되어 있은 접점들을 순간적으로 때려주는 상태가 되어 스파크가 발생되며 이에따라 화재가 발생될 위험이 있었고, 또 키이(29)와 스위치(23)의 위치 조정이 잘못되면 스위치(23)가 동작되지 않아 레인지를 작동시킬 수 없게되는 불량현상이 빈발하였으며, 도어부분을 통해 고주파가 새어나오는 것을 효과적으로 방지하여 주지 못하게 되는등의 문제점들이 있었다.Conventionally, as shown in FIG. 3, when the door 27 is closed, the key 29 installed on the door 27 directly presses the contact of the micro switch 23 to operate the switch 23. Since the force of the spring 24 that pulls the key 29 acts to press the contact of the switch 23 directly because the door 27 is closed, the force of the spring 24 in the switch 23 There was a risk of sparking due to the moment of hitting the formed contacts instantaneously, and there was a risk of fire. There was a problem that the poor phenomenon that can not operate the frequent, and do not effectively prevent the high frequency leakage through the door portion.
본 고안은 이러한 문제점들을 해결하기 위해 각 마이크로 스위치를 키이가 직접 동작시켜 주지 않고 누름편에 의해 동작되게 하여 주도록 고안한 것으로 첨부 도면에 의하여 상세히 설명하면 다음과 같다.The present invention is designed to allow each micro switch to be operated by a pressing piece without directly operating the key to solve these problems.
몸체(1)의 소정위치에 각기 한쌍의 고정편(2)(2′)을 일체로 돌출되게 형성하여 마이크로스위치(3)(3′)(3″)를 각각 고정 부착하고, 스위치(3)(3′)사이에는 인장스프링(4)에 의해 서로 당겨지게 누름편(5)(5′)을 회동자재토록 착설하며, 스위치(3″)의 상측에는 안내홈(6a)이 형성된 눌림캠(6)이 일체로 연결된 누름편(5″)을 인장스프링(4′)으로 당겨지게 착설하고, 도어(7)에 인장스프링(8)으로 탄력 설치되게 착설한 키이(9)의 저면에는 누름부(10)를 돌출되게 형성하여서된 것이다.A pair of fixing pieces 2, 2 'are formed to protrude integrally at predetermined positions of the body 1, and the micro switches 3, 3', 3 " Between the 3 ', the pressing piece 5, 5' is installed so as to be rotatably pulled by the tension spring 4, and the pressing cam having a guide groove 6a formed on the upper side of the switch 3 ". 6) The pressing piece 5 ″ connected integrally is installed to be pulled by the tension spring 4 ', and the pressing part is mounted on the bottom of the key 9 which is installed to be elastically installed with the tension spring 8 on the door 7. (10) is to be formed to protrude.
이와같이된 본 고안은 도어(7)를 열게되면 제1a도에서 보는 바와같이 각 누름편(5)(5′)(5″)은 스프링(4)(4′)의 수축력에 의해 당겨져 마이크로스위치(3)(3′)(3″)의 접점과 떨어지게되므로 이들 스위치는 동작을 하지 않기때문에 각 구동부에 전원공급이 차단되어 레인지는 도어(7)가 열린상태에서는 작동시킬 수 없게되는 것이며, 반대로 레인지를 사용하고져할 때에는 작동시킬 수 없게되는 것이며, 반대로 레인지를 사용하고져 할 때에는 도어(7)를 완전히 닫아주어야 되는데 이때는 제1b도에서 보는 바와같이 키이(9)가 몸체(1)내로 들어가면서 그 끝부분은 누름편(5)(5′)사이로 들어가 이들을 상하로 벌려주게되므로 스프링(4)은 늘어나게되고 누름편(5)(5′)은 각각 스위치(3)(3′)의 접점을 눌러주게되어 이들 스위치가 동작되게 하여준다.When the door 7 is opened, the present invention as described above shows that each pressing piece 5, 5 ', 5 " is pulled by the contracting force of the spring 4, 4' as shown in FIG. 3) Since these switches do not operate because they are separated from the contacts of (3 ′) (3 ″), the power supply is cut off at each drive unit, and the range cannot be operated when the door 7 is open. In the case of using the range, the door 7 must be completely closed. In this case, as shown in FIG. 1B, the key 9 enters the body 1 and the end thereof is closed. The springs (4) are extended and the pressing pieces (5) (5 ') press the contacts of the switches (3) (3'), respectively, because they enter between the pressing pieces (5) (5 ') and spread them up and down. Let these switches work.
이때 스위치(3)(3′)를 고정시켜주는 일측 고정편(2)들은 누름편(5)(5′)의 끝부분에 닿게되어 이들 누름편이 과도하게 접점을 눌러주지 않게하여 주는 작용을 하며, 또한 키이(9)의 저면에 돌출된 누름부(10)는 눌림캠(6)의 안내홈(6a)을 통과하면서 누름편(5″)을 회동시켜 주므로 스프링(4′)은 늘어나게되고 누름편(5″)의 하부끝은 스위치(3″)의 접점을 눌러주게 되므로 이 스위치도 동작되고 이에따라 레인지의 각 구동부에 전원이 공급되기 때문에 레인지를 작동시킬 수 있게되는 것이다.At this time, the one side fixing piece (2) fixing the switch (3) (3 ') is in contact with the end of the pressing piece (5) (5') so that these pressing pieces do not press the contact excessively. In addition, since the pressing portion 10 protruding from the bottom of the key 9 rotates the pressing piece 5 ″ while passing through the guide groove 6a of the pressing cam 6, the spring 4 'is extended and pressed. Since the lower end of the piece 5 ″ presses the contact point of the switch 3 ″, the switch is also operated and thus the range can be operated because power is supplied to each drive unit of the range.
이와같이 작동되는 본고안은 키이가 각 스위치의 접점을 직접 눌려주지 않기 때문에 스위치의 수명이 길어지며 스파크현상이 발생되지 않아 안전하게 사용할 수 있으며, 또 각 누름편이 접점을 눌려주게되므로 스위치동작이 확실하게 이루어지게 됨은 물론 레인지의 기능에 따라 일부 스위치가 필요없을 때에는 해당스위치를 제거하여 사용할 수도 있으며, 다수의 스위치가 필요할 때에는 병렬로 연결 사용해도 되고, 특히 하나의 키이로 각 스위치를 동시에 작동시킬 수 있게되는 등 매우 실용적인 고안이다.In this work, the key does not press the contact of each switch directly, so the life of the switch is long and there is no spark phenomenon, so it can be used safely. In addition, depending on the function of the range, when some switches are not needed, the corresponding switches can be removed and used.When multiple switches are needed, they can be connected in parallel, and each switch can be operated simultaneously with one key. Etc. It is a very practical design.
