Description

전자레인지의 도어 파손에 의한 안전장치Safety device by damage to door of microwave oven

제1도는 전자레인지의 도어에서 투시창부위를 일부절결해 보인 예시도.1 is an exemplary view showing a part of the see-through window in the microwave oven door.

제2도는 제1도의 측단면도.2 is a side cross-sectional view of FIG.

제3도는 투시창의 유리면에 안전장치의 센서를 설치한 상태도.3 is a state in which the sensor of the safety device is installed on the glass surface of the viewing window.

제4도는 마스크부에 안전장치의 센서를 설치한 상태도.4 is a state in which a sensor of the safety device is installed in the mask unit.

제5도는 본 고안 안전장치의 전체구성을 설명하기 위한 블록다이어 그램.Figure 5 is a block diagram for explaining the overall configuration of the safety device of the present invention.

본 고안은 전자레인지의 도어부에서 유리(Grass) 또는 마스크(Mask)가 깨어졌을 경우 내부의 마이크로 웨이브(Micro Wave)의 누설을 방지하기 위한 안전장치에 관한 것이다.The present invention relates to a safety device for preventing the leakage of the internal microwave (Micro Wave) when the glass (Grass) or mask (Mask) in the door portion of the microwave oven.

종래 전자레인지의 도어는 단순히 양면 유리사이에 마스크만을 내설한 상태이므로 유리가 깨지거나 마스크가 파손되면 내측이 마이크로 웨브가 누출될 염려가 많고 이로인해 위험사고가 발생될 우려가 많은 문제점이 있었다.Since the door of the conventional microwave oven simply insulated the mask between the two-sided glass, when the glass is broken or the mask is broken, there is a lot of concerns that the inside of the micro-web leaks, and there is a risk that a dangerous accident occurs.

본 고안은 도어를 형성하는 유리면이나 마스크에 저항선을 착접시켜 이를 내측의 안전차단장치와 경보장치에 연결하므로서 유리면이나 마스크가 변형 또는 파손될 경우 안전 장치에 의해 경보발동과 아울러 마그네트론의 전원이 차단되게하여 위험없이 안전하게 사용할수 있게함을 목적으로 안출한 것인바, 이를 첨부도면에 의하여 상세히 설명하면 다음과 같다.The present invention connects the resistance wire to the glass surface or mask forming the door and connects it to the safety barrier device and the alarm device on the inner side. It is devised for the purpose of being able to use safely without risk, described in detail by the accompanying drawings as follows.

내. 외측 유리면(2)(3)사이에 마스크(4)를 넣은 상태로 착접시켜 투시창을 형성한 전자레인지도어(1)에 있어서 유리면(2)(3)의 중앙면이나 마스크(4)의 사방 모서리부에 저항선(5)을 착접시켜 연결선이 앰프의 증폭기(7)를 통해 릴레이(8)에 의해 전원차단장치(9) 및 경보기(10)와 연결되게한 것이다.of mine. In the microwave oven door 1 in which the sight glass is formed by contacting the mask 4 between the outer glass surfaces 2 and 3 to form a viewing window, the center surface of the glass surfaces 2 and 3 or the corners of the mask 4 on all sides. The resistance wire 5 is brought into contact with the negative electrode so that the connecting wire is connected to the power interrupter 9 and the alarm 10 by the relay 8 through the amplifier 7 of the amplifier.

이와같이된 본 고안은 불의의 사고에 의해 전자레인지도어(1)의 유리면(2)(3)이나 마스크(4)가 파괴 또는, 변형되었을 경우에는 저항선(5)의 저항치가 변화하고 변화되는 저항값은 제5도의 블록다이어그램에서와 같이 앰프의 증폭기(7)에서 증폭변화된 신호를 트리거하여 릴레이(8)를 작동시킴과 동시 경보기(10)및 마그네트론전원 차단장치(9)의 스위치를 off 작동시키므로 마이크로 전자파의 발생이 정지됨과 동시에 경보장치가 울리게되는 것이다.The present invention thus achieved is the resistance value of the resistance wire 5 changes and changes when the glass surface 2, 3 or the mask 4 of the microwave oven door 1 is destroyed or deformed due to an accident. As shown in the block diagram of FIG. As soon as the generation of electromagnetic waves stops, an alarm device sounds.

또한 도어(1)의 구조상 마스크(4)는 유리면(2)(3)이 감싸고 있기 때문에 마스크(4)가 변형되거나 파괴되기전에 먼저 유리면(2)(3)이 파괴되므로 감지기(Sensor)는 제3도의 상태처럼 유리면(2)(3)에만 설치하여도 충분히 안전하게 사용할 수 있게 된다.In addition, since the mask 4 is structurally enclosed by the glass surfaces 2 and 3, the glass surface 2 and 3 are first destroyed before the mask 4 is deformed or destroyed. Even if it is installed only on the glass surfaces 2 and 3 as in the state of 3 degrees, it can be used safely enough.

또다른 방법은 제4도에서와 같이 마스크(4)의 사방모서리부에 클립식 센서(H)를 착접시키는 것이며 이 경우 마스크(4)가 클립식 센서(H)에서 충분히 빠져나올 정도로 협착되게하므로서 마스크(4)가 파괴되거나 변형되면 그 충격으로 사방모서리중에서 센서(H)가 하나만 빠져도 A, B사이의 저항이 변화되어 저항치가 작아지므로 증폭기 및 안정장치에 의해 콘트롤될 수 있는 것이다.Another method is to contact the clip type sensor H to the four corners of the mask 4 as shown in FIG. 4, in which case the mask 4 is narrowed enough to escape from the clip type sensor H. If 4) is destroyed or deformed, the resistance between A and B changes even if only one sensor (H) falls out of the corners due to the impact, and thus the resistance value becomes small, and thus can be controlled by the amplifier and the stabilizer.

이렇게된 본 고안은 도어(1)에 감지장치를 설치하여 사고 발생시 안전차단장치를 작동시키게 하므로서 위험한 전자파 방출을 막을수 있고 안전하게 사용할수 있는 효과가 있는 것이다.The present invention has the effect that can be used safely to prevent dangerous electromagnetic radiation emissions by installing a detection device in the door (1) to operate a safety shut-off device in the event of an accident.
