[기술분야][Technical Field]

본 발명은 전자렌지의 콘트롤패널내에 설치하여 도어의 임의적 개방을 단속하게 한 도어잠금장치에 관한 것으로, 특히 콘트롤패널외부로 돌출된 노브를 좌 또는 우측으로 돌림에 의해 이 노브축상에 설치된 피니언이 랙을 동작시켜 도어측면의 요부에 랙이 삽탈됨에 따라 잠금 또는 해제되는 것을 마이크로스위치가 감지하여 전원을 온·오프시키도록 한 전자렌지의 도어잠금장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door locking device installed in a control panel of a microwave oven for intermittent opening of a door, and in particular, a pinion installed on this knob shaft by turning a knob protruding out of the control panel to the left or right. The present invention relates to a door lock device of a microwave oven which turns on and off a power by detecting a microswitch that a lock is released or released as a rack is inserted into a main part of a door side by operating the controller.

[발명의 배경][Background of invention]

일반적으로 전자렌지의 도어에는 콘트롤패널 하측에 설치된 도어개방버튼에 의해 동작되는 도어잠금장치를 구비하고 있는데, 이 도어잠금장치는 도어(1)의 개방측 내면에 고정후크(2)가 설치되고 몸체(3)에는 요홈(4)을 형성하여 이 요홈(4) 내부에 락커를 구비하며, 상기 락커의 작동을 콘트롤패널 하측의 도어개방버튼(5)에 의해 작동되게 구성하며, 도어(1)의 고정측인 힌지축상에는 탄성체를 권취하여 도어(1)가 항상 외측으로 개방되려는 힘이 작용되게 탄지된 상태로 구성되어 있다.In general, the door of the microwave oven is provided with a door locking device which is operated by a door opening button installed at the bottom of the control panel. The door locking device has a fixing hook (2) installed on the inner side of the door (1) and a body. (3) is formed with a recess (4) provided with a locker inside the recess (4), the operation of the locker is configured to be operated by the door open button (5) on the lower side of the control panel, On the hinge axis on the fixed side, the elastic body is wound up and the door 1 is always held so as to exert a force to open to the outside.

이와 같은 종래의 도어잠금장치는 도어(1)의 후크(2)가 요홈(4) 내부의 락커에 의해 걸려져 잠금된 상태로 도어가 폐쇄되어 있으며, 개방시에는 도어개방버튼(5)을 누름에 의해 후크가(2)를 고정하고 있는 락커가 잠금을 해제시켜 도어(1)의 힌지축상에 탄지된 탄성력에 의해 도어(1)가 개방되는 작용을 하도록 되어 있다.In the conventional door lock device, the door is closed while the hook 2 of the door 1 is locked by the locker inside the recess 4, and when the door is opened, the door open button 5 is pressed. By this, the locker to which the hook 2 is fixed is released, and the door 1 is opened by the elastic force held on the hinge axis of the door 1.

또한 후크(2)가 락커에 걸려 있는 상태에서는 전원이 차단되며 잠금이 해제된 상태에서는 전원이 입력되어 조리실 내부의 조명이 켜지도록 구성되어 있다.In addition, when the hook 2 is locked to the locker, the power is cut off, and in the unlocked state, the power is input to configure the lighting inside the cooking chamber.

이러한 구성으로 된 도어잠금장치는 도어(1)를 개폐함에는 별 지장이 없으나 순간적인 오동작이나 어린이들의 장난등에 의해 도어개방버튼을 누르면 일시에 개방하게 되어 필요에 의하지 않고 임의로 개방됨에 따른 작동상에 기기성능이 저하되거나 사고의 우려가 발생되는 제문제가 있어 왔다.The door locking device having such a configuration has no problem in opening and closing the door 1, but when the door opening button is pressed by a momentary malfunction or children's mischief, the door is temporarily opened, and the operation of the door locking device is performed randomly. There has been a problem that the performance of the device is degraded or there is a risk of an accident.

[발명의 목적][Purpose of invention]

본 발명은 전술한 바와 같은 제반문제를 해소하고 도어의 필요치 않는 임의적 개폐를 방지토록 함으로써 전자렌지를 보호하고 어린이들의 장난으로부터 발생되는 사고의 위험을 극력 억제토록 한 전자렌지의 도어 잠금장치를 제공함에 그 목적이 있는 것이다.The present invention is to solve the problems described above and to prevent unnecessary opening and closing of the door to protect the microwave oven and provide a door lock device of the microwave to suppress the risk of accidents caused by mischief of children to the maximum. The purpose is.

[발명의 요약][Summary of invention]

본 발명은 콘트롤패널 내부에 설치되는 안내가이드에 안내지지되는 랙과, 이 랙에 접속되는 피니언이 노브축상에 연결되고 상기 랙 하측에는 마이크로스위치를 설치하여 콘트롤패널 외부로 돌출된 노브를 돌려줌에 의해 도어측면에 형성된 요부에 상기 랙이 삽탈됨에 따라 잠금, 해제되며 이를 마이크로스위치가 감지하여 전원을 온, 오프시키도록 구성한 것이다.The present invention provides a rack which is guided by a guide guide installed inside the control panel, and the pinion connected to the rack is connected to the knob shaft, and by installing a micro switch on the lower side of the rack, by turning a knob that protrudes out of the control panel. The rack is locked and released as the rack is inserted into the recess formed on the side of the door, and the micro switch detects this and configures the power to be turned on and off.

[발명의 구체적 실시예에 대한 설명][Description of Specific Embodiment of the Invention]

이하 본 발명의 일예시적 실시도면에 의거 구성 및 작용효과를 보다 상세히 설명하면 다음과 같다.Hereinafter, the configuration and operation effects based on the exemplary embodiment of the present invention will be described in detail.

본 발명의 도어잠금장치는 제2도 및 제3도에 도시되어 있는 바와 같이 콘트롤패널의 내부 상측에 안내가이드(11)를 설치하고, 장방형 요홈(12)이 상기 안내가이드(11)에 끼워지며 상측에는 기어(13)가 형성되며 하측에는 요부(14)를 형성한 랙(15)를 구비하고, 이 랙(15)의 상면기어(13)부에 접속되는 피니언(16)이 전방의 노브축(17)상에 설치되고, 이 노브축(17) 일단에는 노브(18)을 형성하되, 이 노브(18)는 콘트롤패널 외측으로 돌출되게 설치하며, 상기 랙(15)의 하측 요부(14)에는 접속돌기(19a)를 갖는 마이크로스위치(19)를 설치한다.In the door locking device of the present invention, as shown in FIGS. 2 and 3, the guide guide 11 is installed on the upper side of the control panel, and the rectangular groove 12 is fitted to the guide guide 11. A gear 13 is formed at an upper side thereof, and a rack 15 having a recessed portion 14 is formed at a lower side thereof, and a pinion 16 connected to the upper gear 13 portion of the rack 15 is a front knob shaft. A knob 18 is formed on one end of the knob shaft 17, and the knob 18 is installed to protrude to the outside of the control panel, and the lower recess 14 of the rack 15 is provided. The micro switch 19 which has the connection protrusion 19a is provided in this.

한편, 전자렌지도어(1)의 개방측 측면에는 고정요홈(20)을 형성하여 구성하며 이러한 구성으로 되는 도어잠금장치는 콘트롤패널 상측에 설치하되, 노브(8)를 제외한 전 구성은 상기 패널내에 내장 설치되게 한다.Meanwhile, the fixing groove 20 is formed on the open side of the microwave oven 1, and the door locking device having such a configuration is installed on the upper side of the control panel. Allow built-in installation

계속해서 본 발명의 작용효과를 설명하면 도어잠금장치가 잠금되어 있는 상태-랙(15)이 도어의 고정요홈(20)에 삽입되어 있으며 상기 랙(15) 하측의 마이크로스위치(19)의 접속돌기(19a)가 요부(14)를 벗어나 랙(15) 저면에 늘려져 전원이 차단된 상태에서 도어(1)를 개방할 경우, 콘트롤패널 상측에 돌출된 노브(18)를 좌측으로 돌리면 노브축(17)상에 설치된 피니언(16)이 랙을 우측으로 밀어주어 이 랙(15)은 안내가이드(11)에 슬라이딩되며 도어(1) 측면의 고정요홈(20)으로부터 빠져나오고 랙(15) 하측에 설치된 마이크로스위치(19)의 접속돌기(19a)가 하측 요부(14)에 위치하게 되어 눌려짐이 해제되므로 전원이 온상태가 되고 잠금장치는 해제된 상태가 된다.Continuing to explain the effect of the present invention, the door lock is locked-the rack 15 is inserted into the fixing groove 20 of the door and the connecting projection of the micro switch 19 below the rack 15. When the door 1 is opened in a state in which the 19a is extended out of the recess 14 to the bottom of the rack 15 and the power is cut off, the knob 18 protruding above the control panel to the left is turned to the left of the knob shaft ( The pinion 16 installed on the side 17 pushes the rack to the right, so that the rack 15 slides in the guide guide 11 and comes out of the fixing recess 20 on the side of the door 1 and under the rack 15. Since the connection projection 19a of the installed microswitch 19 is located at the lower recessed portion 14 and the release is released, the power is turned on and the locking device is released.

이후 콘트롤패널 하측의 도어개방버튼(15)을 누르면 도어(1)의 후크(2)가 락커로부터 해제되어 힌지축에 탄지되어 있는 탄성력에 의해 도어(1)를 개방시킬 수 있는 것이다.Then, when the door open button 15 of the lower control panel is pressed, the hook 2 of the door 1 may be released from the locker to open the door 1 by an elastic force supported on the hinge shaft.

또한 이와는 반대로 도어(1)를 폐쇄하여 잠금할 경우에는 도어(1)를 닫아 후크(2)가 락커에 걸려지게 한 상태에서 노브(18)를 우측으로 돌리면 노브축(17)상에 연결된 피니언(16)이 랙(5)을 좌측으로 밀어주어 랙(5)이 도어측면의 고정요홈(20)에 삽입되며 랙(5) 하측에 설치된 마이크로스위치(19)의 접속돌기(19a)는 랙(15) 저면에 눌려지게 되어 전원이 차단되고 도어가 잠금되는 것이다.On the contrary, when the door 1 is closed and locked, when the knob 18 is turned to the right while the door 1 is closed and the hook 2 is locked to the locker, the pinion connected to the knob shaft 17 16) the rack 5 is pushed to the left so that the rack 5 is inserted into the fixing recess 20 on the side of the door, and the connecting protrusion 19a of the micro switch 19 installed below the rack 5 is provided with the rack 15 ) It is pressed on the bottom and the power is cut off and the door is locked.

따라서 본 발명은 순간적인 오동작이나 어린이들의 장난등으로 인해 도어개방버튼을 눌러 필요에 의하지 않고 임의적으로 도어가 개방됨을 방지되게 함으로써 전자렌지의 작동시에 발생될 수 있는 작동불량이 해소됨은 물론 기기를 보호하고 어린이들의 장난으로 인한 사고의 위험을 방지할 수 있어 기기의 안전성이 향상되게 한 잇점이 있는 것이다.Therefore, the present invention, by pressing the door open button due to a momentary malfunction or children's mischief to prevent the door to open arbitrarily without the need to solve the malfunction that may occur during the operation of the microwave as well as the device It can protect and prevent the risk of accidents caused by children's mischief, thereby improving the safety of the device.
