Abstract
본 발명은 전자 유도가열 조리기 있어, 하나의 인버터 회로로서 다수개의 워킹 코일을 동작시킬 수 있도록하여 회로의 구성을 최소화하고, 다수개의 워킹 코일의 출력제어를 실행하게 될 때 발생하게 되는 간섭음을 방지하며, 또한 스위칭 손실을 줄일 수 있도록 한 다출력 제어를 위한 공진형 전자유도 가열 조리 장치에 관한 것이다.The present invention is an electromagnetic induction heating cooker, it is possible to operate a plurality of working coils as one inverter circuit to minimize the configuration of the circuit, and to prevent the interference sound generated when performing the output control of the plurality of working coils In addition, the present invention relates to a resonant electromagnetic induction heating cooking device for multi-output control to reduce switching loss.
종래 주파수 제어에 의한 경우 인접한 워킹 코일 사이에 동작주파수의 차이에 의한 간섭음이 발생하게 되어 워킹 코일의 정확한 출력제어가 이루어지지 않게 되며, 또한 각각의 구성된 인버터만큼 정류수단과 입력단의 정류수단으로부터의 전압을 평활 및 필터링하게 되는 L,G필터를 구성하여야 만 하므로서, 전체 회로가 복잡하게 되며, 기기구성에의 경제성이 결여되는 문제점이 발생하게 된다.According to the conventional frequency control, interference noises are generated between the working coils adjacent to each other by the difference in operating frequency, so that the accurate output control of the working coils is not performed. Since the L and G filters for smoothing and filtering voltages must be configured, the entire circuit becomes complicated and there is a problem in that the economy of device configuration is lacking.
본 발명은 회로구성을 최소화하여 인버터 회로를 구성하고 공통의 정류수단으로부터 인가되는 전원을 입력받아 하나의 인버터 회로로서 시분할 제어를 통하여 두개의 워킹 코일의 출력제어가 이루어지도록 하므로서, 간섭음에 의한 문제를 방지하고, 소프트 스위칭 방식을 이용 스위칭 손실을 줄일 수 있도록 한 다출력 제어를 위한 공진형 전자유도 가열 조리 장치이다.The present invention configures the inverter circuit by minimizing the circuit configuration and receives the power applied from the common rectifying means, so that the output control of the two working coils is made through time division control as one inverter circuit, thereby causing problems due to interference sound. It is a resonant electromagnetic induction heating cooking device for multi-output control to prevent the loss and to reduce the switching loss using a soft switching method.
