Abstract

본 발명의 유도가열조리기는, 스위칭 소자부의 구동에 의해 워킹코일 측으로 공진전압을 제공하는 공진 콘덴서에 연결되어 조리용기의 위치에 따른 공진전압 변화를 감지하여 제어부로 전송하기 위한 공진콘덴서 전압 검지부와, 상기 공진콘덴서 전압 검지부로부터 감지된 전압값에 따라 스위칭소자측에 인가되는 전류량을 제어하기 위한 제어부를 포함하여 구성되며, 상기와 같이 조리용기의 위치에 따른 공진콘덴서 전압을 검지하여 그에따라 스위칭소자에 입력되는 전류량을 조절함으로써 종래의 전류검출부 사용시 전류검출부의 용량 및 크기 증가에 의한 원가상승없이 스위칭 소자와 공진콘덴서의 손상을 방지할 수 있는 효과가 있다.The induction heating cooker of the present invention is connected to a resonant capacitor providing a resonant voltage to the working coil side by driving the switching element unit, and a resonant capacitor voltage detector for detecting a change in the resonant voltage according to the position of the cooking vessel and transmitting it to the control unit; And a control unit for controlling the amount of current applied to the switching element side according to the voltage value sensed by the resonance capacitor voltage detection unit, and detecting the resonance capacitor voltage according to the position of the cooking vessel as described above. By adjusting the amount of input current, damage to the switching element and the resonant capacitor can be prevented without a cost increase due to an increase in the capacity and size of the current detector when using the current detector.
