Abstract

본 발명은 유도가열 조리기 있어, 할프 브리지형 인버터를 입력측에 병렬구성하여 하나의 인버터 회로로서 다수개의 워킹 코일을 동작시킬 수 있도록 하여 회로의 구성을 최소화하고, 다수개 워킹 코일의 출력제어를 실행하게 될 때 발생하게 되는 간섭음을 방지하도록 한 다출력 제어를 위한 듀얼 할프 브리지(Dual Half-Bridge)형 전자유도 가열 조리 장치에 관한 것이다.The present invention has an induction heating cooker, in which a half-bridge type inverter is configured in parallel on the input side so that a plurality of working coils can be operated as one inverter circuit, thereby minimizing the circuit configuration and performing output control of the plurality of working coils. The present invention relates to a dual half-bridge type electromagnetic induction heating cooking device for multi-output control to prevent an interference sound generated when the electronic device is generated.

종래 전자유도 가열 조리 장치에 있어 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,C필터를 구성하여야 만 하므로서, 전체 회로가 복잡하게 되며, 기기구성에의 경제성이 결여되는 문제점이 발생하게 된다.In the conventional electromagnetic induction heating cooking apparatus, interference noises are generated between the working coils adjacent to each other, so that accurate output control of the working coils is not performed. Since the L and C filters for smoothing and filtering the voltage from the filter must be configured, the entire circuit becomes complicated and there is a problem in that the economy of the device configuration is lacking.

본 발명은 다출력 제어를 위한 전자유도 가열 조리 장치에 있어서 발생되는 상기와 같은 문제점을 해결하기 위하여 할프 브리지형 전자유도 가열 조리기를 제안하는 바, 다수개의 할프 브리지형 인버터를 입력측에 병렬 구성하여 하나의 인버터 회로를 구성하여, 회로구성을 최소화하고, 시분할 제어를 통하여 워킹 코일의 출력제어를 이루도록 하므로서, 가열판간의 간섭음의 발생을 방지하고자 하여, 하나의 인버터 회로로서, 다수개의 가열판을 동작시킬 수 있도록 하는 것이다.The present invention proposes a half-bridge type electromagnetic induction heating cooker in order to solve the above problems generated in the electromagnetic induction heating cooking device for multi-output control, a plurality of half-bridge type inverter in parallel to the input side In order to prevent the occurrence of interference noise between the heating plates by minimizing the circuit configuration and to achieve the output control of the working coil through time division control, a plurality of heating plates can be operated as one inverter circuit. To ensure that
