Description

전자렌지의 도어 밀폐장치Microwave Door Sealing Device

본 발명은 전자렌지에 관한 것으로, 더욱 상세하게는 조리실을 개폐하는 도어에 관한 것이다.The present invention relates to a microwave oven, and more particularly to a door for opening and closing the cooking chamber.

일반적으로 전자렌지는 마그네트론에서 기본파 2450MHz의 고주파를 조리실 내부로 방사하여 음식물에 함유된 수분의 분자배열을 반복 변환시킴으로써, 분자들간의 마찰열에 의해 음식물을 조리하는 기구이다. 이러한 기능을 하는 전자렌지는 본체 내부에 조리실과 전장품실이 구획되게 형성되고, 조리실을 개폐하는 도어가 힌지결합되어 있다. 전장품실에는 조리실로 고주파를 방사하는 마그네트론, 마그네트론에 고전압을 인가하는 고압트랜스, 외기의 공기를 흡입하여 전장품을 냉각시키고 열교환된 공기를 조리실로 강제송풍하여 조리시 발생되는 냄새를 제거하는 냉각팬 등이 설치된다.In general, a microwave oven is a device that cooks food by frictional heat between molecules by radiating a high frequency of 2450 MHz fundamental wave in a magnetron into a cooking chamber and repeatedly converting a molecular arrangement of moisture contained in the food. The microwave oven having such a function is formed so that the cooking compartment and the electrical equipment compartment are partitioned inside the main body, and the door for opening and closing the cooking compartment is hinged. In the electrical equipment room, a magnetron that radiates high frequency to the cooking chamber, a high pressure transformer that applies high voltage to the magnetron, a cooling fan that sucks air from outside air to cool the electrical equipment and forcibly blows heat exchanged air into the cooking chamber to remove odors generated during cooking. This is installed.

이러한 전자렌지는 조리실에 피조리물을 넣고 도어를 닫은 상태에서 작동시키면, 마그네트론에서 조리실로 고주파가 방사되고, 고주파에 조사된 피조리물은 수분의 분자배열이 급속하게 변환됨으로써 이들의 마찰열에 의해 조리된다. 아울러 냉각팬의 작동으로 열이 발생되는 전장품이 냉각되고 조리실의 공기는 외부공기와 순환됨으로써, 조리시 발생되는 냄새와 수분은 외부로 배출된다.When the microwave oven is placed in a cooking chamber and operated with the door closed, the high frequency is radiated from the magnetron to the cooking chamber, and the cooked substance irradiated at the high frequency is rapidly transformed due to the frictional heat of the molecules. Cooked In addition, the electrical equipment that generates heat by the operation of the cooling fan is cooled and the air in the cooking chamber is circulated with the outside air, the smell and moisture generated during cooking are discharged to the outside.

그러나 이러한 전자렌지는 피조리물이 분자변환에 따른 마찰열에 의해서만 조리가 수행되기 때문에 부피가 큰 피조리물을 조리하는데에는 많은 시간이 소요되며, 이의 조리시간을 단축하는데에는 그 한계가 있다. 또한 조리과정중에 조리실의 공기가 순환됨으로써, 피조리물의 수분이 지속적으로 증발 배출되어 고유의 음식맛이 덜하게 된다.However, since the microwave oven is cooked only by frictional heat due to molecular transformation, it takes a lot of time to cook a bulky workpiece, and there is a limitation in shortening the cooking time thereof. In addition, the air in the cooking chamber is circulated during the cooking process, so that the moisture of the cooked product is continuously evaporated and discharged, thereby reducing the inherent food taste.

본 발명은 이러한 문제점을 해결하기 위한 것으로, 본 발명의 목적은 도어의 배면에 가요성을 갖는 실링부재를 테두리부분을 따라 설치함으로써, 도어가 폐쇄되면 실링부재가 본체의 앞면판과 밀착되어 도어의 배면과 본체의 앞면판 사이에 틈새가 발생되지 않아 본체 내부에 형성된 조리실이 밀폐되는 전자렌지를 제공하는 것이다.The present invention is to solve this problem, an object of the present invention is to install a sealing member having flexibility on the back of the door along the rim, when the door is closed, the sealing member is in close contact with the front plate of the main body of the door There is no gap between the back and the front plate of the main body to provide a microwave oven is sealed cooking chamber formed inside the main body.

본 발명에 따른 전자렌지는 이들에 도시한 바와 같이, 외관을 이루는 본체(10) 내부에 앞면이 개방된 조리실(20)과 전장품실(30)이 구획되게 형성되어 있다. 전장품실(30)에는 고주파를 발진하여 조리실(20)로 방사하는 마그네트론(31), 마그네트론(31)에 고전압을 인가하는 고압트랜스(미도시) 등이 설치된다. 이 때, 마그네트론(31)은 도파부(미도시)만을 통해서 고주파가 조리실(20)로 방사되도록 용접수단을 이용하여 견고하게 고정되어 있다.As shown in the present invention, the microwave oven according to the present invention is formed such that the cooking chamber 20 and the electrical equipment compartment 30 having an open front face are partitioned inside the main body 10 forming the exterior. The electrical equipment room 30 is provided with a magnetron 31 that oscillates high frequency and radiates to the cooking chamber 20, and a high voltage transformer (not shown) that applies a high voltage to the magnetron 31. At this time, the magnetron 31 is firmly fixed by using welding means such that high frequency is radiated to the cooking chamber 20 through only the waveguide (not shown).

본체(10)의 앞면부에는 조리실(20)을 개폐하며 조리실(20)을 볼 수 있도록 투시부(41)가 마련된 도어(40)가 회전운동 가능하게 힌지결합되어 있고, 다수의 조작버튼이 마련된 콘트롤판넬(32)이 설치되어 있다. 미설명부호 42는 도어(40)의 닫힘시 본체(10) 내부로 삽입되는 걸쇠장치로서, 이것은 도어(40)의 조리실(20) 닫힘 상태를 유지하는 기능을 하며 콘트롤판넬(32)에 설치된 푸시버튼을 누르게 되면 본체(10)로부터 분리되어 도어(40)가 개방된다.The front part of the main body 10 is opened and closed to the cooking chamber 20, the door 40 provided with a see-through portion 41 so as to see the cooking chamber 20 is hinged rotatably rotatable, and provided with a plurality of operation buttons The control panel 32 is installed. Reference numeral 42 is a latch device that is inserted into the main body 10 when the door 40 is closed, which serves to keep the cooking chamber 20 of the door 40 closed, and is installed on the control panel 32. When the button is pressed, the door 40 is opened by being separated from the main body 10.

그리고 본체(10)의 앞면판(10a)과 대향 접촉하는 도어(40)의 배면에는 본 발명의 특징적인 요소로 도어(40)의 닫힘시 조리실(20)을 완전히 밀폐시키는 가요성 재질의 실링부재(44)가 구성되며, 조리실(20)이 소정기압 이상이면 증기를 배출하는 증기배출부재(45)가 설치되어 있다. 실링부재(44)는 도어(40) 배면의 테두리부분을 따라 설치되는데, 이의 구조를 도 2를 참조하여 상세히 설명하면 다음과 같다. 도어(40)의 배면에는 이에 도시한 바와 같이, 오목하게 형성된 안착부(44c)가 테두리를 따라 형성되며, 여기에는 체결공(44b)이 일정간격 이격되게 천공된다. 그리고 신축재로 이루어진 실링부재(44)에는 결합돌기(44a)가 마련되어 있어서, 결합돌기(44a)를 체결공(44b)에 끼워 실링부재(44)를 고정하면 실링부재(44)의 일부는 안착부(44c)의 외부로 노출된다. 한편, 증기배출부재(45)는 일종의 안전장치로 압력밥솥 등에서 널리 사용되고 있기 때문에 이에 대한 상세한 구조 설명은 생략한다. 미설명부호 43은 쵸크수단으로 마그네트론(31)에서 조리실(20)로 방사된 고주파가 외부로 누설되는 것을 방지한다.And on the back of the door 40 which is in contact with the front plate 10a of the main body 10 as a characteristic element of the present invention, a sealing member made of a flexible material that completely closes the cooking chamber 20 when the door 40 is closed. 44 is provided and the vapor discharge member 45 which discharges steam when the cooking chamber 20 is more than predetermined | prescribed atmospheric pressure is provided. The sealing member 44 is installed along the edge of the rear surface of the door 40. The structure thereof will be described in detail with reference to FIG. As shown therein, a recess 44c is formed along the rim of the rear surface of the door 40, and fastening holes 44b are punctured at predetermined intervals. In addition, the sealing member 44 made of elastic material is provided with a coupling protrusion 44a. When the coupling member 44a is fitted into the fastening hole 44b to fix the sealing member 44, a part of the sealing member 44 is seated. It is exposed to the outside of the portion 44c. On the other hand, since the steam discharge member 45 is widely used in a pressure cooker as a kind of safety device, detailed structure description thereof will be omitted. Reference numeral 43 is a choke means to prevent the high frequency radiated from the magnetron 31 to the cooking chamber 20 to leak to the outside.

다음에는 이와 같이 구성된 본 발명에 따른 전자렌지의 작동을 설명한다. 우선, 도어(40)를 개방하고 조리실(20)에 피조리물을 넣은 후 다시 걸쇠장치(42)가 본체(10) 내부로 삽입되어 걸려지도록 도어(40)를 닫게 되면, 도어(40) 배면에 돌출되게 마련된 실링부재(44)는 본체(10) 앞면판(10a)과 접촉하게 된다. 신축재로 이루어진 실링부재(44)가 탄성 변형되면서 본체(10) 앞면판(10a)과 밀착됨으로써, 도어(40)의 배면과 본체(10) 앞면판(10a)과의 틈새가 없게 되고 이에 따라 조리실(20)은 완전히 밀폐된다. 이 상태에서 콘트롤판넬(32)에 구성된 조작버튼을 조작하여 조리행정을 수행하면, 마그네트론(31)에서 기본파 2450 MHz의 고주파가 조리실(20) 내부로 방사된다. 피조리물은 이러한 고주파에 의해 조사되어 분자배열이 급속하게 변환되고 이들의 마찰열에 의해 조리가 수행된다.Next will be described the operation of the microwave oven according to the present invention configured as described above. First, when the door 40 is opened and the cooking material 20 is placed in the cooking chamber 20, the door 40 is closed so that the clasp 42 is inserted into the main body 10 and hooked again. The sealing member 44 provided to protrude in contact with the front plate 10a of the main body 10. As the sealing member 44 made of elastic material is elastically deformed and closely adhered to the front plate 10a of the main body 10, there is no gap between the rear surface of the door 40 and the front plate 10a of the main body 10. The cooking chamber 20 is completely sealed. In this state, when the cooking stroke is performed by operating the operation button configured on the control panel 32, the high frequency of the fundamental wave 2450 MHz is radiated from the magnetron 31 into the cooking chamber 20. The cooked object is irradiated by such a high frequency so that molecular arrangements are rapidly converted and cooking is performed by their frictional heat.

이 때, 실링부재(44)에 의해 밀폐 구성된 조리실(20)은 피조리물에 함유된 수분이 증발되어 상당한 고압이 형성되기 때문에, 적은 열량으로도 높은 효율을 얻을 수 있다. 즉, 피조리물을 짧은 시간내에 조리를 할 수 있어 전력소모가 줄어들며, 피조리물에 함유된 수분이 지속적으로 빠져나가는 것이 방지됨으로써 음식물이 가지고 있는 본래의 맛을 유지할 수 있게 된다. 한편, 조리실(20)이 소정 압력 이상으로 형성되면, 증기배출부재(45)를 통해 증기가 외부로 배출되어 압력이 저하된다.At this time, the cooking chamber 20 configured to be sealed by the sealing member 44 can obtain a high efficiency even with a small amount of heat since the moisture contained in the cooked material is evaporated and a considerable high pressure is formed. In other words, the cooking can be cooked within a short time to reduce power consumption, and the moisture contained in the cooking can be prevented from continuously draining, thereby maintaining the original taste of the food. On the other hand, if the cooking chamber 20 is formed at a predetermined pressure or more, the steam is discharged to the outside through the steam discharge member 45 to reduce the pressure.

이상에서 상세히 설명한 바와 같이, 본 발명에 따른 전자렌지는 도어의 배면에 가요성을 갖는 실링부재를 테두리부분을 따라 설치하였다. 따라서 도어가 폐쇄되면 실링부재가 본체의 앞면판과 밀착되어 도어의 배면과 본체의 앞면판 사이에 틈새가 발생되지 않아 조리실이 밀폐됨으로써, 조리수행중에 고압으로 형성되어 피조리물은 짧은 시간에 조리되며 음식물이 가지고 있는 본래의 맛이 유지되는 이점이 있다.As described in detail above, the microwave oven according to the present invention has a sealing member having flexibility on the rear surface of the door along the edge portion. Therefore, when the door is closed, the sealing member is brought into close contact with the front plate of the main body so that no gap is generated between the rear surface of the door and the front plate of the main body so that the cooking chamber is sealed. It has the advantage that the original taste of food is maintained.
