The purpose is to.
이를 실현하기 위하여 본 발명 도어의 투시창에는 투시창의 이상 상태를 감지하도록 다수의 도선구조를 갖는 도선스크린을 부착시켜 구성하였다.In order to realize this, the see-through window of the door of the present invention is configured by attaching a conductor screen having a plurality of conductor structures to detect an abnormal state of the see-through window.
Description
본 발명은 전자레인지에 관한 것으로서, 특히 음식물의 가열 및 조리를 위한 전자레인지의 고내를 개/폐시키는 도어구조에 관한 것이다.The present invention relates to a microwave oven, and more particularly to a door structure for opening and closing the inside of the microwave oven for heating and cooking food.
종래 전자레인지의 도어구조를 살펴보면 도 1 에 도시된 바와같이 도어(2)의 중간에 레인지 내부를 들여다 볼 수 있는 다공의 구조를 갖는 투시창(6)이 있고, 상기 투시창(6)은 전자레인지 내부의 습기가 다공부로 새어나오지 않게 하기 위하여 도어의 내부쪽에서 비닐류의 재질을 갖는 도어스크린(3)으로 씌워져 있으며, 상기 도어(2)의 일측에는 도어를 닫히게 하기 위한 래치(4)가 형성되고, 상기 래치(4)는 전자레인지의 래치홀(5)에 끼워지게 된다. 이때, 래치홀(5) 내측에 위치하는 릴레이에 의해 도어의 닫힘을 감지하여 도어가 닫히지 않은 상태에서는 전자레인지가 정상동작 하지 않도록 구성되어 있다.Referring to the door structure of a conventional microwave oven, as shown in FIG. 1, there is a viewing window 6 having a porous structure for looking into the inside of the range in the middle of the door 2, and the viewing window 6 is inside the microwave oven. In order to prevent moisture from leaking into the perforated part, the inside of the door is covered with a door screen 3 having a vinyl material. On one side of the door 2, a latch 4 for closing the door is formed. The latch 4 is fitted into the latch hole 5 of the microwave oven. At this time, by detecting the closing of the door by a relay located inside the latch hole (5) is configured so that the microwave oven does not operate normally in the state that the door is not closed.
그러나 종래 전자레인지용 도어의 안전장치는 도어의 닫힘만을 감지하기 때문에 도어의 투시창이 파손되어 다공부의 찌그러짐이나 훼손이 있어도 도어가 닫힌 상태로 감지가 되면 정상동작을 하게되는데, 이러한 상태에서는 도어 투시창의 다공부로 전자파가 누설될 수 있는 문제가 있었다.However, since the safety device of the conventional microwave oven door only detects the closing of the door, if the door's sight window is broken and there is a dent or damage in the porous part, the door is normally closed and the door is operated normally. There was a problem that the electromagnetic wave can leak into the porous portion of.
또한 투시창의 경미한 찌그러짐이나 파손에도 충분한 누설의 소지가 있고 특히 도어의 투시창은 도어의 내측에 있기 때문에 사용작 외관으로는 투시창의 사소한 파손을 알기가 어려운 문제점이 있었다.In addition, there is a possibility of a sufficient leakage even in the slight crushing or breakage of the sight window, and in particular, because the sight window of the door is inside the door, there is a problem that it is difficult to know the minor damage of the sight window in terms of use.
본 발명은 상기한 바와같은 종래 기술의 문제점을 해결하기 위하여 발명된 것으로 도어의 투시창에는 투시창의 이상 상태를 감지하도록 다수의 도선구조를 갖는 도선스크린을 부착시킴으로서, 도어스크린의 파손으로 인한 전자파누설을 미연에 방지할 수 있도록 하는데 목적이 있다.The present invention has been invented to solve the problems of the prior art as described above by attaching a conductor screen having a plurality of conductor structures to detect the abnormal state of the sight window to the viewing window of the door, to prevent electromagnetic leakage due to damage of the door screen The purpose is to prevent it in advance.
도 1 은 종래기술에 의한 전자레인지 구조도.1 is a microwave oven structure diagram according to the prior art.
도 2 는 본 발명의 도어 구조도.2 is a door structure diagram of the present invention.

이하, 본 발명을 참부도면을 참조하여 이하에서 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the true drawings.
도 2 는 본 발명의 도어구조를 나타낸 것으로 도어(102)의 중앙에는 전자레인지 내부를 들여다 볼 수 있도록 다공의 구조를 갖는 투시창(106)이 있고, 상기 투시창(106)은 고내에서 발생하는 습기 및 이물질이 다공부를 막지 않도록 도어스크린(103)으로 씌워져 있는데, 상기 도어스크린(103)은 스크린 일면에 투시창(106)의 다공부보다 큰 메쉬(mesh) 또는 라인을 갖는 도선이 장착되었다.Figure 2 shows a door structure of the present invention, the center of the door 102 has a viewing window 106 having a porous structure to look inside the microwave oven, the viewing window 106 is moisture and The foreign matter is covered with a door screen 103 so as not to block the pores, the door screen 103 has a conductive wire having a mesh or line larger than the porous portion of the see-through window 106 on one side of the screen.
도면중 미설명 부호 104 는 래치를 나타낸다.In the figure, reference numeral 104 denotes a latch.
이와같이 구성되는 본 발명의 동작을 이하에서 살펴본다.The operation of the present invention configured as described above will be described below.
전자레인지 내부에 조리할 음식물을 넣고 본 발명의 도어를 닫으면 도어의 개/폐 및 투시창(106)의 파손여부를 검지하여 정상상태인 경우에는 전자레인지의 동작이 시작된다.When the food to be cooked in the microwave is placed and the door of the present invention is closed, the operation of the microwave is started in the normal state by detecting the opening / closing of the door and the damage of the see-through window 106.
만약 투시창(106)의 일부분이 파손 혹은 찌그러진 상태에서는 도어스크린(103)상의 도선의 단락여부를 검지하여 도어의 이상상태에서는 동작이 되지 않도록 하게 된다.If a part of the see-through window 106 is damaged or crushed, the short-circuit of the conducting wire on the door screen 103 is detected so that the door does not operate in an abnormal state of the door.
이상 설명한 바와같이 본 발명의 도어장치는 전자레인지의 도어가 닫혀있더라도 투시창의 파손여부를 확인한 후 전자레인지가 동작될 수 있도록 하여 전자파의 누설을 미연에 방지하고 사용자의 안전을 도모하는 효과가 있다.As described above, the door apparatus of the present invention has an effect of preventing the leakage of electromagnetic waves in advance and ensuring the safety of the user by allowing the microwave oven to operate after checking whether the sight glass is damaged even if the door of the microwave oven is closed.
