본 고안은 전자레인지의 도어 부분을 누설되는 고주파를 차단하기 위한 누설방지 장치에 관한 것이다.The present invention relates to a leakage preventing device for blocking high frequency leaking the door portion of the microwave oven.
종래의 전자레인지는 제3도에서 보는 바와 같이 고주파가 누설되는 것을 방지하기 위해 고가의 전파흡입체(R)를 내측커버(A)로 부착하였기 때문에 원가가 상승됨은 물론 내측커버(A)의 형태가 제약을 받음으로 인하여 디자인에도 영향을 주고 또 도어(D) 자체의 두께(1)가 두꺼워서 그 두께만큼 가열실용량이 좁게되는 등의 결점이 있었다.In the conventional microwave oven, as shown in FIG. 3, an expensive radio wave absorber R is attached to the inner cover A in order to prevent high frequency leakage, thereby increasing the cost and forming the inner cover A. Due to the restriction, the design also has an effect, and the thickness (1) of the door (D) itself is so thick that the heating capacity is narrowed by the thickness.
본 고안의 이와같은 점들을 해결하기 위해 고안한 것으로 가열실의 용량을 효율적으로 증대시키는 구조로 구성의 감소화를 도모하고 조립성 및 디자인성의 향상을 기할 수 있도록 고안한 것으로 첨부 도면에 의거 상술하면 다음과 같다.It is designed to solve these points of the present invention and designed to reduce the structure and improve the assembly and design of the structure to efficiently increase the capacity of the heating chamber. As follows.
외측커버(1)와 내측커버(2) 사이에 다수의 관통공(4)을 뚫은 절곡편(5)을 사주면에 형성한 브라켓트(2)를 내측커버(2)의 결착편(6)에 의해 고정되게 착설하고, 내부면(7')이 외측으로 절곡된 접촉판(7)을 내측커버(2)의 내부면에 끼워지도록 부착하여서 된 것이다.The binding piece 6 of the inner cover 2 has a bracket 2 formed on the circumferential surface of the bent piece 5 having a plurality of through holes 4 drilled between the outer cover 1 and the inner cover 2. It is installed so that it is fixed, and the contact plate 7 whose inner surface 7 'is bent outward is attached so that it may be fitted to the inner surface of the inner cover 2. As shown in FIG.
미설명부호 "8"은 쵸오크공간이며, "9"는 접촉 보조판이고, "10"는 가열실이며, "11"은 장석보조 부재이다.Reference numeral "8" is a choke space, "9" is a contact auxiliary plate, "10" is a heating chamber, and "11" is a feldspar auxiliary member.
이와같이된 본 고안은 도어가 닫혔을 때를 가정해 보면 제2도에 도시된 바와 같이 고주파는 접촉 보조판(9)과 접촉판(7)의 밀착 상태에 따라 누설이 양이 달라지므로 제2도의 접촉판(7)같이 구조 변경을 시킨 것으로 접촉판(7)은 고주파를 상쇄 적정길이를 취할수 있는 λ/4의 이상형을 접촉 시켜주므로써 초오크 방식의 시일역활을 할 수가 있다.In the present invention, when the door is closed, as shown in FIG. 2, the high frequency is different depending on the contact state of the contact auxiliary plate 9 and the contact plate 7, so the amount of leakage varies. By changing the structure like the plate 7, the contact plate 7 can act as a seal of the choke type by bringing the high frequency into contact with an ideal type of lambda / 4 which can take the appropriate length.
접촉판(7)에서 상쇄되지 않고 누설되는 전파는 프라켓트(3)에서 2차적으로 쵸오크 시일을 형성하는 데 이때 수평 방향의 전파는(g)로써, 수직 방향의 전파는 (a+d)의 형상 공간을 지나면서 최종적으로 고주파가 상쇄되는 구조를 갖는 도어의 구조이다.Radio waves leaking without being canceled in the contact plate 7 form the choke seal secondaryly in the plaquette 3, where the horizontal wave is (g) and the vertical wave is (a + d It is a structure of a door having a structure in which the high frequency is finally canceled while passing through the shape space of).
즉, 접촉판(7)의 길이는 가열실내의 고주파가 누설되었을 경우 상쇄 시킬 수 있는 λ/4 이상을 취해준다. (, λ:파장의 길이, f:주파수, c:빛의 속도) 그리고로 형태를 취할 수가 있다.That is, the length of the contact plate 7 takes λ / 4 or more that can be canceled when the high frequency in the heating chamber leaks. ( , λ: wavelength, f: frequency, c: speed of light) Can take the form
λg:관내파장, a:WAVE GUIDE의 치수) 이때 ab이고 c3d 정도의 일반적인 수식을 성립 시킬 수가 있다. 이때 전파가 누설될 수 있는 길, 즉(p)의 상태를 실제적으로 상쇄시킬 수가 있는 관통공(4)의 형상은(g)의 형태 및 수치로서로 완성시킨 후 관통공(4)의 1/2정도로 임의 형태를 취한다. λg: in-tube wavelength, a: dimensions of WAVE GUIDE) b and c 3d general formulas can be established. At this time, the shape of the through hole 4 that can substantially cancel the road where the radio waves can leak, that is, the state of p is a shape and a numerical value of (g). After completing the process, take an arbitrary form with about 1/2 of the through hole (4).
이상과 같은 구조의 도어로 설계 했을 시에는 도어의 두께 및 전파의 상쇄 효과도 양호한, 한층 더 향상된 전자레인지의 도어로 효과를 사용할 수가 있다.When the door is designed as described above, it is possible to use the door furnace effect of the microwave oven, which is further improved in the effect of offsetting the thickness and the radio wave of the door.
이와 같이 도어의 구조를 형성하였을 경우 누설고주파에 대한 상쇄 효과가 적고 향상되고 부품수의 단순화에 따른 원가절감 및 조립 과정의 단순화가 가능하며, 또 가열실의 공간을 도어의 감소된 두께(b) 만큼 더 활용할 수가 있어 캐비넷트의 효율을 증가 시킬수가 있고 도어폭의 슬림화로 디자인을 포함하는 설계를 쉽게 할 수가 있는등 매우 실용적인 고안이다.In this way, when the door structure is formed, the offset effect on the leakage high frequency is less and improved, the cost reduction and assembly process can be simplified by simplifying the number of parts, and the space of the heating chamber is reduced in thickness (b). As it can be used more, it is possible to increase the efficiency of the cabinet and make the design including the design easier by slimming the door width.
