본 고안은 고주파 자계를 사용하는 유도 조리기에 있어서 누설되는 고주파 자속에 의해 외부의 통신기기나 기타의 수신장치에서 일어나는 통신 장애를 방지하게한 것에 주안점을 둔 고주파 유도 가열 조리기의 누설자계 차폐 장치에 관한 것이다.The present invention relates to a leakage magnetic shield device of a high frequency induction heating cooker focused on preventing communication disturbances occurring in an external communication device or other receiving device by high frequency magnetic flux leaking in an induction cooker using a high frequency magnetic field. will be.
종래의 고주파 유도 가열 조리기는 약 20-25KHZ의 고주파 자계를 발생시켜 이것을 자성체 용기 밑면에 통과 시킴으로써 자속 변화에 의해 생긴 와전류가 용기 자체의 저항 성분에 흘러 주율열로 발생 가열이 된다.Conventional high frequency induction heating cooker generates a high frequency magnetic field of about 20-25KHZ and passes it through the bottom of the magnetic container, so that the eddy current generated by the change of magnetic flux flows into the resistance component of the container itself and is generated as main heat.
이때 유도 가열 코일에서 발생한 일부의 고주파 자속이 용기 밑면을 통과하지 않고 외부로 누설되는데 이것이 외부 기기에 영향을 주며 용이가 작을 경우 더욱 큰 문제점이 된다.At this time, some of the high-frequency magnetic flux generated in the induction heating coil leaks to the outside without passing through the bottom of the container, which affects the external device and becomes a bigger problem when the ease is small.
본 고안은 종래의 이러한 문제점을 해결하기 위하여 유동 가열 조리장치의 세라믹판 하부에 일정 부분의 자계통과 부분을 제외하고 전자파 차폐용 도로를 도포하여 샤시에 접지시키므로서 고주파 자계의 외부 누설을 방지할 수 있게 안출한 것으로 이를 첨부도면에 의하여 상세히 설명하면 다음과 같다.The present invention can prevent the external leakage of the high-frequency magnetic field by applying the electromagnetic shielding road to the chassis by applying a road for electromagnetic shielding except for a portion of the magnetic field in the lower portion of the ceramic plate of the flow heating cooking apparatus to solve the conventional problems. If described in detail by the accompanying drawings as follows.
유도가열기(1) 하부본체(2)에 세라믹판 받침대(3)를 나사(4)로 체결한후 이에 세라믹판(5)을 고정판(6)으로 고정한 통상의 것에 있어서 세라믹판(5) 저부에 자계통과부분(A)을 제외하고 전자파 차폐용 도로를 도포하여 도포층(7)을 형성하고 외곽 부분에 알루미늄박(8)을 접착하여 전기적 접촉 저항을 줄이고 하부 본체(2) 내측에 링 터미널(9)을 가진 접지선(10)을 나사(4a)와 너트(11)로 고정하여서된 것으로 도면중 미설명부호 12는 유도 가열 코일판을 표시한 것이며 13은 유도가열코일이고 14는 자성체 용기를 표시한 것이다.The bottom of the ceramic plate 5 in a conventional one in which the ceramic plate base 3 is fastened to the lower body 2 of the induction heater 1 with a screw 4 and then the ceramic plate 5 is fixed with the fixing plate 6. Except for the magnetic field passing portion (A), the electromagnetic wave shielding road is applied to form a coating layer (7), and the aluminum foil (8) is adhered to the outer portion to reduce the electrical contact resistance and the ring terminal inside the lower body (2). The ground wire 10 having the 9 is fixed with a screw 4a and a nut 11, wherein reference numeral 12 denotes an induction heating coil plate, 13 is an induction heating coil, and 14 is a magnetic container. It is displayed.
이와 같이 구성된 본 고안은 유도가열기(1) 내부에서 발생한 고주파 자계가 하부 본체(2) 밑을 통과하지 않고 누설되려다 상부에 설치된 세라믹판(5)의 도포층(7) 부분에 도달되면 세라믹판(5)과 알루미늄박(8) 그리고 고정판(6) 세라믹판 받침대(3)와 하부 본체(2)를 통해 하부본체(2) 내부에 설치된 링 단자(9)와 접지선(10)을 통해 접지 되면서 외부 누설을 방지하게 된다.According to the present invention configured as described above, when the high frequency magnetic field generated inside the induction heater 1 does not pass under the lower body 2 and reaches the portion of the coating layer 7 of the ceramic plate 5 installed thereon, the ceramic plate (5) and the aluminum foil (8) and the fixed plate (6) through the ceramic plate base (3) and the lower body (2) and grounded through the ring terminal (9) and the ground wire (10) installed inside the lower body (2) It will prevent external leakage.
이때 알루미늄박(8)을 사용하는 것은 세라믹판(5)의 도포층(7) 부분과 하부 본체(2)까지를 전기적으로 완전히 연결시켜 접촉 저항을 줄여 주는 것이다.In this case, the use of the aluminum foil 8 is to electrically connect the application layer 7 portion of the ceramic plate 5 to the lower body 2 completely to reduce the contact resistance.
이상과 같이된 본 고안은 유도 가열 조리기의 세라믹판 하부에 일정 자계통과 부분을 제외하고 전자파 차폐용 도료층을 형성한후 세라믹판 외곽부분을 알루미늄박으로 접착하여 하부 본체에 까자 접지 가능케 함으로서 고주파 자계가 외부로 누설되어 외부 통신기기와 수신 장치에 장애를 가져와 잡음을 일으키거나 소음이 발생되는 일이 없어 외부 통신기기와 수신 장치에 영향을 미치지 않는 유용의 고안안 것이다.The present invention as described above forms a coating layer for shielding electromagnetic waves except for a portion of the magnetic field passing through the lower portion of the ceramic plate of the induction heating cooker, and then attaches the outer portion of the ceramic plate with aluminum foil so that it can be grounded to the lower body. This is a useful design that does not affect the external communication device and the receiving device because the leakage to the outside does not cause an external communication device and the receiving device to cause noise or noise.
