Provided is an induction heating apparatus with an overheat preventing function for a vehicle, which is able to detect a current consumption of a cooling water pump and to effectively prevent an overheat from occurring even when there is no heat medium in a flow path inside a case. According to the present invention, the induction heating apparatus with the overheat preventing function for the vehicle comprises: the case which has the flow path in which a heat medium flows; an induction heater installed on the flow path of the case; an inlet cover and an outlet cover, which are engaged with the case to have an inlet pipe and an outlet pipe, which are respectively connected to the flow path; the cooling water pump installed by being connected to the inlet pipe side or the outlet pipe side and to forcibly circulate the heat medium in the flow path of the case; a circuit board engaged with the case on the opposite side to the side of the inlet cover and the outlet cover, having a controller unit; and a circuit cover which wraps around and protects the circuit board, while being engaged with the case. The controller unit is able to stop an operation of the induction heater when the detected current consumption of the cooling water pump is 80% or less of a normal value.
본 발명은 냉각수 펌프의 소비전류를 감지하여 케이스 내부의 유로에 열매체가 없는 경우에도 과열이 발생하는 것을 효과적으로 방지하는 것이 가능한 과열방지기능이 있는 자동차용 인덕션 히팅장치를 제공한다. 본 발명의 과열방지기능이 있는 자동차용 인덕션 히팅장치는 열매체가 흐르는 유로가 형성되는 케이스와, 케이스의 유로에 설치되는 인덕션히터와, 케이스에 결합되고 유로에 각각 연결되는 입구파이프와 출구파이프가 형성되는 입출구덮개와, 입구파이프쪽 또는 출구파이프쪽에 연결되어 설치되고 열매체를 케이스의 유로로 강제 순환시키는 냉각수 펌프와, 입출구덮개 반대쪽에서 케이스에 결합되고 컨트롤러부가 탑재되는 회로기판과, 회로기판을 감싸 보호하며 케이스에 결합되는 회로덮개를 포함하고, 컨트롤러부는 감지된 냉각수 펌프의 소비전류가 정상값의 80% 이하인 경우에는 인덕션히터의 작동을 정지시키도록 구성한다.
