Induction cooker with hardware protection function

Abstract

The invention discloses an induction cooker capable of hardware protection. The induction cooker comprises a protection circuit, an MCU and a wireless communication module; the wireless communication module receives a control instruction from a mobile terminal and sends the control instruction to the MCU, and the MCU controls the protection circuit to implement protection motions according to the control instruction; the protection circuit comprises an IGBT, an optical coupler, a first diode, a second voltage-stabilizer tube, a first triode, first to third capacitors and first to ninth resistors; and one end of the first resistor, one end of the second resistor, one end of the third resistor, one end of the fifth resistor and one end of the seventh resistor are all connected to the signal input end. The induction cooker capable of hardware protection has the advantages that a user can know operation condition of the induction cooker at any time and place and implement corresponding control, and the circuit safety and reliability are higher.

Description

technical field [0001] The invention relates to the field of electromagnetic cookers, in particular to an electromagnetic cooker with a hardware protection function. Background technique [0002] IGBT is an insulated gate bipolar transistor, which is widely used in high-power inverter circuits, such as induction cookers and high-power switching power supplies. As a key device of this type of circuit, the IGBT often causes too much current to flow due to some abnormal conditions, causing the IGBT to be damaged or even blown up, and even cause a fire. Therefore, the protection of IGBT is a major issue related to the safety, stability and service life of the induction cooker. However, the circuit part of the current induction cooker lacks a corresponding circuit protection function, or the circuit protection function is not perfect, resulting in low safety and reliability of the circuit. In addition, the user cannot understand the operating conditions of the induction cooker ...
