Description
본 발명은 래치보디(latch body)가 없는 전자렌지에 관한 것으로서, 더욱 상세하게는 도어의 개폐에 의해 작동되는 안전스위치가 래치보디 아닌 본체의 브라켓에 직접 장착됨으로써 원가절감 및 생산성 향상을 기한, 래치보디가 없는 전자렌지에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a microwave oven without a latch body, and more particularly, to a microwave oven having a latch body and a safety switch which is operated by opening and closing a door, The present invention relates to a microwave oven having no body.
일반적인 전자렌지의 작동은 도어에 장착된 후크래치(hook latch)가 그 하단에 부착된 스프링의 탄성력에 의해 래치보디의 걸림부에 걸리면서 제1안전스위치와 제2안전스위치의 접점돌기를 온.오프 시킴으로써 안전한 작동이 이루어졌다.The operation of a general microwave oven is such that a hook latch mounted on a door is caught by a latching portion of a latch body by an elastic force of a spring attached to a lower end of the door latch so that a contact protrusion of a first safety switch and a second safety switch is turned on Safe operation was achieved.
즉, 종래 래치보디가 장착된 전자렌지의 잠금장치는, 도1 및 도2와 같이, 전자렌지의 본체(1)에 회전식으로 개폐되도록 설치된 도어(3)와, 도어(3)의 일측에 장착된 후크래치(6) 및 그 하단에 부착된 스프링(7)으로 구성된다.1 and 2, the locking device of the microwave oven to which the conventional latch body is mounted includes a door 3 installed to be rotatably opened and closed on the main body 1 of the microwave oven, And a spring 7 attached to the lower end of the hook latch 6.
그리고, 상기 도어(3)의 후크래치(6)에 대응되는 본체(1)의 전면판(2)에는 상하 2개소의 삽입홈(2')(2)을 형성하는 한편, 전면판(2) 일부를 내측으로 절곡 하여 형성한 브라켓(4)에는 래치보디(5)를 설치하고 그 상하 적정부위에 제1스위치(8) 및 제2스위치(9)를 각각 장착하였다.The front plate 2 of the main body 1 corresponding to the hook latch 6 of the door 3 is provided with two upper and lower insertion grooves 2 ' A bracket 4 formed by bending a part inward is provided with a latch body 5, and a first switch 8 and a second switch 9 are attached to the upper and lower titles, respectively.
따라서, 상기와 같이 구성된 전자렌지는, 도어(3)가 닫히면 먼저 후크래치(6)의 걸림단(6')(6)이 전면판(2)의 삽입홈(2')(2)을 통과하여 래치보디(5)의 걸림편(5')(5)에 걸려진다. 이 때 도어(3)는 전면판(2)에 밀착되는 동시에 상기 후크래치(6)의 상부 걸림단(6')은 제1안전스위치(8)의 접점돌기(8')를 누르게 되며, 하부 걸림단(6)은 역시 래치보디(5)상에 설치된 회동체(10)의 일측 선단부에 걸어져 그 회전에 의해 제2안전스위치(9)의 접점돌기(9')를 누르게 된다.Therefore, when the door 3 is closed, the hook 6 '(6) of the hook latch 6 passes through the insertion groove 2' (2) of the front plate 2 (5 ') (5) of the latch body (5). At this time, the door 3 is brought into close contact with the front plate 2 and the upper latching end 6 'of the hook latch 6 presses the contact projection 8' of the first safety switch 8, The latching end 6 is also hooked on one end of the rotary body 10 provided on the latch body 5 and presses the contact projection 9 'of the second safety switch 9 by the rotation.
한편, 도어(1)가 열릴 경우에는 후크래치(6)의 걸림단(6')(6)이 삽입홈 (2')(2)에서 빠져나오는 동시에 제1,2스위치(8)(9)의 접점돌기(8')(9)를 누르고 있던 후크래치(6)의 걸림단(6')과 회동체(10)의 일측 선단부가 서로 분리되면서 스위치를 해제시킨다.When the door 1 is opened, the latching ends 6 ', 6 of the hook latch 6 come out of the insertion grooves 2', 2 and at the same time the first and second switches 8, The latching end 6 'of the hook latch 6 which has pressed the contact projection 8', 9 of the rotary body 10 and one end of the rotary body 10 are disengaged from each other and the switch is released.
그러나, 상기와 같이, 제1,2안전스위치를 설치하기 위한 래치보디가 필요함으로 인하여, 제조원가의 상승 및 관련공수의 증대를 초래하는 문제점이 있었다.However, since the latch body for installing the first and second safety switches is required as described above, there has been a problem that the manufacturing cost is increased and the related airflow is increased.
또한, 래치보디에 안전스위치를 취부하거나 수리시 그를 분리하는 작업이 쉽게 이루어지지 않는 등 작업효율이 저하되는 단점도 있었다.In addition, there is also a disadvantage in that the operation of attaching the safety switch to the latch body or separating the safety switch at the time of repair is not easy and the working efficiency is lowered.
본 발명은, 상기와 같은 문제점을 해결하기 위하여 안출된 것으로, 그 목적은 기존의 래치보디 사용을 배제하고 본체 전면판의 브라켓 상에 직접 안전스위치를 설치함으로써, 원가절감 및 생산성 향상을 기할 수 있는, 래치보디 없는 전자렌지를 제공하는 데 있다.SUMMARY OF THE INVENTION The present invention has been made in order to solve the above problems, and it is an object of the present invention to provide a safety switch that directly removes a conventional latch body and mounts a safety switch on a bracket of a main body front plate, And a microwave oven without a latch body.
본 발명의 이러한 목적은, 전면판 상에 형성된 브라켓에 직접 안전스위치를 고정함으로써 달성된다.This object of the present invention is achieved by fixing the safety switch directly to the bracket formed on the front plate.

이하, 본 발명 실시예의 래치보디가 없는 전자렌지를 첨부도면에 의거하여 상세히 설명한다.BEST MODE FOR CARRYING OUT THE INVENTION A microwave oven without a latch body according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.
먼저, 본 발명 실시예의 래치보디가 없는 전자렌지의 잠금장치는, 도3,4와 같이, 상하 2개소에 삽입홈(2')(2)을 가지는 전면판(2)상에 형성된 브라켓(4)과, 브라켓(4)의 상하 2개소에 제1안전스위치(8) 및 제2안전스위치(9)가 고정된 구조이다.First, as shown in FIGS. 3 and 4, the locking device of the microwave oven without the latch body of the embodiment of the present invention is provided with a bracket 4 (see FIG. 4) formed on the front plate 2 having insertion grooves 2 ' And the first safety switch 8 and the second safety switch 9 are fixed to the upper and lower portions of the bracket 4, respectively.
이때, 도어(3)의 후크래치(6) 걸림단(6')(6)이 제1,2안전스위치(8)(9)의 접점돌기(8')(9')를 누를수 있도록 상기 브라켓(4)의 적정위치에 나사공(30)(30') (31)(31')이 형성되어 있다.At this time, in order to press the contact protrusions 8 ', 9' of the first and second safety switches 8, 9, the hooking end 6 ', 6 of the hook latch 6 of the door 3 presses The brackets 30, 30 ', 31 and 31' are formed at appropriate positions of the bracket 4.
상기 제1,2안전스위치(8)(9)는 상기 브라켓(20)의 나사공(30)(30')(31)(31')을 관통하는 나사(40)로 고정된다.The first and second safety switches 8 and 9 are fixed by a screw 40 passing through the screw holes 30, 30 ', 31 and 31' of the bracket 20.
이렇게 구성된 래치보디가 없는 전자렌지는, 도어(3) 닫힘시 후크래치(6)의 걸림단(6')(6)이 전면판(2)의 삽입홈(2')(2)을 통과하여 브라켓(20)에 장착된 제1,2안전스위치(8)(9)의 접점돌기(8')(9')를 누르고, 도어가 열림시에는 후크래치(6)의 걸림단(6')(6)이 제1,2안전스위치의 접점돌기(8')(9')에서 떨어짐과 동시에 각 스위치를 경유하는 회로가 차단된다.When the door 3 is closed, the latching end 6 '(6) of the hook latch 6 passes through the insertion groove 2' (2) of the front plate 2 The contact protrusions 8 'and 9' of the first and second safety switches 8 and 9 mounted on the bracket 20 are pressed and the latching end 6 'of the hook latch 6 is opened when the door is opened. (6 ') is separated from the contact protrusions (8') and (9 ') of the first and second safety switches, the circuit passing through each switch is cut off.
이상 설명한 바와 같이, 본 발명의 전자렌지는, 안전스위치를 브라켓에 직접 설치함으로써 부품수 감소에 따른 원가절감의 효과가 있다.INDUSTRIAL APPLICABILITY As described above, the microwave oven of the present invention has the effect of reducing the cost due to the reduction in the number of parts by directly installing the safety switch on the bracket.
또한, 조립공정을 단순화함으로써 생산성향상의 장점도 있다.In addition, there is also an advantage of improving the productivity by simplifying the assembling process.
