Embodiment Construction
[0043] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0044] The invention provides a heating control method of an induction cooker, the heating control method of the induction cooker is mainly used in the control system of the induction cooker, and is used to avoid the load increase of the IGBT switch tube in the induction cooker due to the material difference of the heated pot. question .
[0045] refer to figure 1 , in one embodiment, the heating control method of the induction cooker includes the following steps:
[0046] Step S10, when the induction cooker is turned on and a pot is detected, the pulse signal output by the voltage comparator in the MCU in the heating control circuit of the induction cooker is obtained, and the number of the pulse signals is counted; The comparison result of the voltage at both ends of the middle coil disc outputs the corresponding...

The invention discloses a heating control method and device of an electromagnetic oven. The heating control method of the electromagnetic oven includes: when the electromagnetic oven is turned on and a pot is detected, the pulse signal output by the voltage comparator in the MCU in the heating control circuit of the electromagnetic oven is acquired, and Count the number of the pulse signals; the voltage comparator outputs the corresponding pulse signal according to the comparison result of the voltage across the coil disc in the electromagnetic oven; the pulse signal output by the voltage comparator according to the preset time Determine the material type of the pot; according to the material type of the pot, determine the opening delay time of the PPG in the MCU, and control the PPG delay time in the MCU according to the opening delay time open. The heating control method of the electromagnetic oven of the present invention can solve the problem that the load of the IGBT switch tube in the electromagnetic oven is aggravated due to the material difference of the pan to be heated, and improves the reliability of the electromagnetic oven.
Description
technical field [0001] The invention relates to the field of electromagnetic heating equipment, in particular to a heating control method and device for an electromagnetic oven. Background technique [0002] At present, the heating control of the induction cooker is controlled by a pulse control signal generated by a PPG (Programmable Pulse Generator, Programmable Pulse Generator) in the MCU. However, in the heating control method of the induction cooker in the prior art, since the opening delay time of the PPG is fixed, when heating pans of different materials, the PPG may be opened at an inappropriate time, for example, when heating When the 430 iron pot, 430 steel pot or 304 steel pot is used, the PPG is turned on in advance, and when the Indian pot is heated, the PPG is turned on with a lag, and the lead turn-on and lag turn-on of the PPG will increase the load on the IGBT switch tube. As a result, the performance of the IGBT switch tube is affected, resulting in low re...
