Further, according to an embodiment of the present invention, as shown in fig. 2, the pot adaptation control method of the electromagnetic heating system further includes:
s4: and controlling the heating power of the electromagnetic heating system according to the adaptation degree of the cooker and the electromagnetic heating system.
That is to say, different target powers are given according to different switching-on pulse widths, and the electromagnetic heating system is further controlled to heat according to the different target powers, that is, the heating power of the electromagnetic heating system is controlled to reach the different target powers.

It should be noted that different types of cookware, for example cookware made of different materials, have different adaptations to the resonance parameters of the electromagnetic heating system, which results in the same current and inconsistent pulse widths for controlling the power switching tubes to be turned on. Therefore, the control module 20 can distinguish different types of cookware by comparing the pulse widths of the power switch tubes controlled to be switched on under the same target power.
The duty ratio of the PPG signal may refer to an on duty ratio, that is, a ratio of on time of the control power switch tube in one cycle to an on period, and the on time of the power switch tube is also an on pulse width of the PPG signal.
Specifically, the control module 20 may set a preset target power, and then control the heating power of the electromagnetic heating system to reach the target power by adjusting the duty ratio of the PPG signal output to the power switch tube.
In the embodiment of the present invention, the control module 20 may first give a preset target power, and then control the heating power of the electromagnetic heating system to reach the preset target power, at this time, the obtaining module 10 obtains the on-pulse width of the PPG signal output to the power switch tube, and determines the degree of adaptation between the cookware and the electromagnetic heating system by corresponding different on-pulse widths to different cookware.

Specifically, according to an embodiment of the present invention, if the on pulse width of the PPG signal is greater than the first preset threshold, the control module 20 determines that the degree of adaptation between the cookware and the electromagnetic heating system is high, and controls the electromagnetic heating system to heat with the first preset power.
According to an embodiment of the present invention, if the on pulse width of the PPG signal is less than or equal to the first preset threshold and greater than the second preset threshold, the control module 20 determines that the degree of adaptation between the cookware and the electromagnetic heating system is a medium degree of adaptation, and controls the electromagnetic heating system to heat with the second preset power, where the second preset power is less than the first preset power.
In one specific example of the present invention, the preset target power may be less than the first preset power and greater than the second preset power.
According to an embodiment of the present invention, if the switching-on pulse width of the PPG signal is less than or equal to the second preset threshold, the control module 20 determines that the degree of adaptation between the cookware and the electromagnetic heating system is low, and controls the electromagnetic heating system to heat with a third preset power, where the third preset power is less than the second preset power.
The first preset threshold and the second preset threshold may be represented in hexadecimal, for example, the first preset threshold may be 9A, and the second preset threshold may be 80.
That is to say, the control module 20 distinguishes the adaptation degree of different cookware and the electromagnetic heating system by comparing the opening pulse widths of the power opening pipes under the same preset target power, and for cookware with good adaptation, the set opening pulse width, namely the first threshold value, can be reached, and the electromagnetic heating system can be heated by applying high power, namely the first preset power. For the cookware with poor adaptability, the set switching-on pulse width, namely the first preset threshold value, cannot be reached, and the lower power, namely the second preset power or the third preset power, can be applied to the electromagnetic heating system for heating.
Therefore, the difference of the cookware is reflected on the opening pulse width of the power switch tube, and then the cookware with poor adaptability is endowed with low power through the difference of the opening pulse width of the power switch tube under the same preset target power, so that the service life of the electromagnetic heating system is effectively prolonged.
In summary, according to the pot adaptation control device of the electromagnetic heating system provided in the embodiment of the present invention, the control module first controls the electromagnetic heating system to operate at the preset target power, then obtains the opening pulse width of the PPG signal output to the power switch tube of the electromagnetic heating system under the preset target power, and determines the adaptation degree between the pot and the electromagnetic heating system according to the opening pulse width of the PPG signal. Therefore, by judging the matching of the cookware and the electromagnetic heating system, the embodiment of the invention can select the proper opening pulse width of the target power switch tube, thereby improving the energy efficiency of the system, reducing the large loss of the system, preventing the over-high temperature of the internal elements of the system, improving the reliability of the product and prolonging the service life of the product.
