In this embodiment, four sets of the same pot detection circuits 4 and coil panels are arranged in the heating area 3, and certainly, two sets or three sets or five sets or six sets may be arranged, but it is not required that the more sets are better, but the more sets are, the more complexity of the installation of the induction cooker, the complexity of the circuit and the load of the circuit are increased. The following will explain the present invention in more detail according to the four groups of pot detection circuits 4 and coil panels.
As shown in fig. 1 and 2, the pot detection circuit 4 includes an IGBT control circuit 40 and an oscillation circuit 41 that are connected to each other, the MCU controller 2 is electrically connected to the IGBT control circuit 40 and the oscillation circuit 41, the MCU controller 2 controls the oscillation circuit 41 to generate two oscillation signals through the IGBT control circuit 40, and the MCU controller 2 obtains the two oscillation signals and detects the specific position of the pot 5 on the heating area 3 according to the two oscillation signals, thereby determining whether the pot 5 is placed on the induction cooker. Specifically, the MCU controller 2 is electrically connected to the IGBT control circuit 40, and is configured to generate a control signal acting on the IGBT control circuit 40 through the MCU controller 2 before the induction cooker starts heating, so that the IGBT control circuit 40 can control the oscillation state of the oscillation circuit 41. In this embodiment, the control signal generated by the MCU controller 2 may be a pulse signal, and when the IGBT control circuit 40 receives the pulse signal, the IGBT control circuit 40 is turned on, so that the oscillation circuit 41 oscillates, and two ends of the oscillation circuit 41 generate two paths of oscillation signals, respectively.
Further, the MCU controller 2 may be implemented by an electronic component having a control function, for example, a single chip microcomputer, the oscillating circuit 41 is an LC resonant unit, and includes an inductor L1 and a resonant capacitor C1 connected in parallel, and the inductor L1 is a coil panel in the induction cooker housing. The embodiment does not limit the specific implementation form of each component in the pot detection circuit 4, and can be selected according to the actual situation. In addition, the induction cooker in this embodiment further includes different modules such as a heating circuit and a display circuit, and the specific composition of the induction cooker may be set according to the actual situation, which should not be limited to this.
Further, the pot detection circuit 4 further comprises a rectifying circuit 42, the rectifying circuit 42 is connected between the power supply 6 and the oscillating circuit 41, and by arranging the rectifying circuit 42 in the pot detection circuit 4, the rectifying circuit 42 is connected to the power supply 6, so that the alternating current output by the power supply 6 can be converted into direct current.

In other words, when having placed pan 5 on the electromagnetism stove, two way oscillating signal that oscillating circuit produced can be absorbed by pan 5 owing to pan 5's damping, and then make the less pulse signal of voltage comparator output quantity, so when the quantity of the pulse signal that MCU controller 2 received is less than preset quantity, confirm that there is pan 5 on this group coil panel, and when the quantity of the pulse signal that receives was greater than or equal to preset quantity, confirm that there is not pan 5 on this group coil panel. In this technical solution, the preset number is 10, that is, when the number of the pulse signals received by the MCU controller 2 is less than 10, it is determined that the group of coil panels has the pot 5, the MCU controller 2 controls the group of coil panels to operate, and when the number of the pulse signals received by the MCU controller 2 is greater than or equal to 10, it is determined that the group of coil panels does not have the pot 5, and the MCU controller 2 controls the group of coil panels to be out of operation.
