Description

전자레인지의 도어개폐장치Microwave Door Opener

제1도는 전자레인지의 도어가 닫힌 상태의 부분 단면도.1 is a partial cross-sectional view of the microwave oven with the door closed.

제2도는 전자레인지의 도어가 열린 상태의 부분 단면도.2 is a partial cross-sectional view of the microwave oven with the door open.

제3도는 정전시 푸쉬레버를 사용하여 문을 여는 상태의 부분 단면도.3 is a partial cross-sectional view of a state in which a door is opened by using a push lever in case of power failure.

본 고안은 스위칭 레버와 솔레노이드(Solenid)를 사유하여, 전자레인지의 도어를 개폐하도록 하므로서 도어를 열때는 즉시 고주파가 차단되어 고주파가 누설되지 않는 정확한 동작을 하며, 정전시에도 푸쉬레버를 동작시키기만 하면 문이 열리면서 고주파 회로가 차단되어 통전이 되어도 고주파가 발생치 않도록한 전자레인지의 도어개폐장치에 관한 것이다.The present invention uses a switching lever and a solenoid to open and close the door of the microwave oven, so when the door is opened, the high frequency is cut off immediately so that the high frequency is not leaked. When the door is opened and the high frequency circuit is cut off and the electricity is supplied to the door opening and closing device of the microwave oven so that no high frequency occurs.

종래에 사용되든 전자레인지의 도어개폐 방법은 본체의 한 부분에 조작봉을 돌출시켜 문을 닫았을 때는 회로가 연결되고 문을 열었을 때에는 회로가 차단되게 하는 장치였으나, 이 방법은 부주의 및 스프링의 고장으로 문을 연상태에서도 회로가 차단되지 않아 고주파가 외부로 누설되는 등 여러가지 문제점이 발생하였으며, 또한 반대로 문을 닫았을 때에는 회로가 잘연결이 되지 않아 조리시간이 지연되기도 하였다.Conventionally, the door opening and closing method of the microwave oven is a device that connects the circuit when the door is closed by protruding the operating rod to a part of the main body and the circuit is blocked when the door is opened. As the circuit is not blocked even when the door is opened, various problems occur such that high frequency is leaked to the outside. In addition, when the door is closed, the cooking time is delayed because the circuit is not connected well.

또한 푸쉬버튼을 이용하여 문을 열고 닫을때 회로가 끊어지게 하거나 연결되게 하는 방법이 안출되기도 하였으나, 이 방법 역시 좋은 효과를 기대할수가 없었다.In addition, a method of breaking or connecting a circuit when a door is opened and closed by using a push button has been conceived, but this method could not be expected to have a good effect.

더우기 외부로 부터의 유입물에 의하여 스위치의 동작을 막기위해 보호편을 설치하였으나, 모든 스위치가 외부 유입물로부터 동시에 보호되지 못하였으며, 보호편을 설치하므로서 인터록 장치(Inter lock)가 복잡하고 고장이 잦아 마이크로스위치의 동작이 확실치 못하였다.Moreover, the protection piece was installed to prevent the operation of the switch by the inflow from the outside, but all the switches were not protected from the external inflow at the same time, and the interlock device was complicated and troubled by installing the protection piece. Frequently, the operation of the microswitches was uncertain.

본 고안은 이와 같은 종래의 폐단을 완전히 해결하기 위하여 안출한 것으로, 전자레인지의 판넬부분에 설치한 터치식 스위치로서, 솔레노이드를 동작시켜, 스위칭레버가 작동되어 전자레인지의 도어를 개폐시키고, 또한 외부에서는 스위치를 절대로 작동할수 없게 하였으며, 부품수를 줄여 원가를 절감토록 하였다.The present invention devised to completely solve such a conventional closed end, a touch switch installed in the panel portion of the microwave oven, by operating the solenoid, the switching lever is activated to open and close the door of the microwave oven, Has never been able to operate the switch, and the cost is reduced by reducing the number of parts.

또한 본원에 의하여 전자레인지의 도어에 손잡이가 필요하지 않으므로 제품포장이 간단하며, 제품포장의 용적이 적어지는 등의 잇점이 있는 것이다.In addition, since the present application does not require a handle on the door of the microwave oven, the product packaging is simple, and the volume of the product packaging is advantageous.

이와 같은 본 고안을 첨부도면에 의하여 상세히 설명하면 다음과 같다.If the present invention as described in detail by the accompanying drawings as follows.

전자레인지의 도어(7) 일측에 후크(4)(4')를 인장스프링(12)(12')으로 탄설하고, 도어가 열렸을때 후코(4)(4')가 일정범위를 벗어나지 않도록 후크스토퍼(13)(13')를 도어 일측에 돌출시킨다.Hooks the hooks (4) and (4 ') with tension springs (12) and (12') on one side of the door (7) of the microwave, and the hooks (4) and (4 ') do not deviate from a certain range when the door is opened. The stoppers 13 and 13 'protrude to one side of the door.

또한 도어(7)를 닫았을때 후크(4)(4')와 맞물릴수 있도록 레인지 본체의 테두리에 걸림턱(19)(19')을 설치하고 걸림턱(19)(19')과 연하여는 도어(7)를 열을 경우 후크(4)(4')를 밀어서 걸림턱(19)(19')에서 벗어나게 하는 스위칭레버(1)를 삽설하며, 이 스위칭레버(1)는 파워레버(9), 연결봉(10), 로드(16)와 연결되었으며, 솔레노이드(8)가 결국 이 스위칭레버(1)를 동작시키도록 구성되어 있다.In addition, when the door 7 is closed, hooking jaws (19) and (19 ') are installed at the edges of the range body so as to be engaged with the hooks (4) (4') and the hooking hooks (19) and (19 ') are connected. In order to open the door 7, the switch lever 1 is inserted into the switch lever 1, which pushes the hooks 4 and 4 'out of the latching jaws 19 and 19'. (9), the connecting rod 10, the rod 16 is connected, the solenoid 8 is configured to eventually operate the switching lever (1).

스위칭레버(1)의 일면에는 안전스위치(5)와 모니터 스위치(6)(6')를 동작시킬수 있는 스위치 접동레버(18)(18')를 돌설하고, 이 작용을 확실하게 하기 위하여 압축스프링(11)을 스위칭레버스토퍼(2)와 스위칭레버(1) 사이에 탄력설치 시킨다. 또한 스위칭레버(1)의 하단에 접해서는 손잡이부분(14')이 전자레인지의 저면(17) 외부로 돌출되게 정전푸쉬레버(14)를 토오션 스프링(15)으로 탄력설치하여 정전시에도 도어(7)를 열수있게 하였다.One side of the switching lever 1 is provided with a switch sliding lever 18 and 18 'capable of operating the safety switch 5 and the monitor switch 6, 6', and a compression spring to ensure this action. (11) is elastically installed between the switching lever stopper (2) and the switching lever (1). In addition, the electrostatic push lever 14 is elastically installed with the torsion spring 15 so that the handle portion 14 'protrudes out of the bottom surface 17 of the microwave oven in contact with the lower end of the switching lever 1. (7) was opened.

도면 미설명 부호 3은 가이드이다.Reference numeral 3 in the drawings is a guide.

이와 같이 구성된 본 고안은 제1도와 같이 도어(7)가 닫힌 상태에서 도어(7)를 열고자할 때에는 전자레인지 몸체 측면의 판넬에 부착된 터치식 스위치(도시생략)에 손을 대면 솔레노이드(8)에 순간적인 전원이 가하여 지므로 솔레노이드(8)에 축설된 로드(16)가 하향운동을 함에 따라 레버 연결봉(10)에 연결된 파워 레버(9)가 중심축(A)을 중심으로 위운동을 하고 동시에 스위칭레버(1)가 상향운동을 하여 스위칭 접동레버(18)(18')가 안전스위치(5)와 모니터스위치(6)(6')로 부터 이탈되므로 전원이 차단됨과 동시에 고주파 발생이 중지되며, 스위칭레버(1)의 선단이 후크(4)(4')를 밀어서 걸림턱(19)(19')에서 이탈시키므로 도어(7)는 자체의 조그마한 탄력으로 열리는 것이다.When the door 7 is opened in the state in which the door 7 is closed as shown in FIG. 1, the present invention configured as described above has a solenoid 8 when a touch type switch (not shown) attached to a panel on the side of the microwave oven body is touched. As momentary power is applied to the rod 16, the rod 16 arranged in the solenoid 8 moves downward, and the power lever 9 connected to the lever connecting rod 10 moves upwardly about the central axis A. At the same time, the switching lever 1 moves upward, and the switching sliding levers 18 and 18 'are separated from the safety switch 5 and the monitor switch 6 and 6'. Since the front end of the switching lever 1 pushes the hooks 4 and 4 'to separate from the latching jaws 19 and 19', the door 7 is opened with its own small elasticity.

한편 제3도는 정전이 되었을때 도어(7)를 여는 방법을 표시한 것으로, 정전시는 전자레인지 저면에 설치된 정전푸쉬레버(14)의 손잡이부분(14')을 전방으로 밀어주면 푸쉬레버(14)가 스위칭레버(1)를 상측으로 밀어주므로 통전시와 동일한 효과를 발휘하여 도어(7)을 열수있으며, 도어(7)가 열린상태에서는 정전푸쉬레버(14)는 토오션 스프링(15)의 힘으로 원위치로 된다. 또한 이 상태에서 통전이 되드라도 안전스위치(5)와 모니터스위치(6)(6')가 이미 단락된 상태이므로 고주파가 누설되는 사례가 전혀없다.On the other hand, Figure 3 shows how to open the door (7) when the power outage, when the power failure pushes the handle portion 14 'of the electrostatic push lever 14 installed on the bottom of the microwave oven push lever 14 ) Pushes the switching lever (1) upwards, thereby opening the door (7) with the same effect as when energizing, and the electrostatic push lever (14) of the torsion spring (15) when the door (7) is open. The force returns to its original position. In this state, the safety switch 5 and the monitor switches 6 and 6 'are already short-circuited even when the power is supplied, so that no high frequency leaks occur.

이상과 같이 본 고안은 솔레노이드를 동작시켜 스위칭레버가 작동하면서 도어가 개폐되도록 하여, 도어의 개폐동작과 스위치 동작이 정확히 이루어지도록 하였으며, 외부에서는 스위치를 절대 작동시킬 수 없게 하여, 안전성을 증대시켰고, 부품수를 줄여 원가를 절감시킬수 있도록 한 특징이 있다.As described above, the present invention allows the door to be opened and closed while the switching lever is operated by operating the solenoid, so that the opening and closing operation and the switch operation of the door are made correctly, and the switch can never be operated from the outside, thereby increasing safety. It has the feature to reduce the cost by reducing the number of parts.
