specific Embodiment 1

[0033] Such as image 3 As shown, a pot self-adaptive electromagnetic heating control method is used to control the above-mentioned electromagnetic heating device, comprising the following steps:

[0034] S1: The setting module sets the corresponding heating power according to the temperature change rate of the IGBT tube, so that it can heat the pot according to the set heating power;

[0035] S2: According to the feedback pulse detection, it is judged whether there is a pot on the electromagnetic heating device that needs to be heated, and the detection signal is sent to the temperature acquisition module;

[0036] S3: When the electromagnetic heating device is working, the temperature acquisition module collects the temperature of the IGBT tube;

[0037] Collect the initial temperature T1 of the IGBT tube, time t1, the induction cooker heats and cooks the pot according to the set heating power P1, and collect the temperature T2 of the IGBT again after Δt time, that is, at t...

specific Embodiment 2

[0041] The difference between this implementation and the first embodiment is that in this embodiment, the heating duty cycle of the IGBT tube is adjusted so that it can be heated according to the set heating power.

[0042] Such as Figure 4 As shown, a pot adaptive electromagnetic heating control method is used to control the above pot adaptive electromagnetic heating system, including the following steps:

[0043] S1: The setting module sets the corresponding heating power according to the temperature change rate of the IGBT tube, so that it can heat the pot according to the set heating power;

[0044] S2: According to the feedback pulse detection, it is judged whether there is a pot on the electromagnetic heating device that needs to be heated, and the detection signal is sent to the temperature acquisition module;

[0045] S3: When the electromagnetic heating device is working, the temperature acquisition module collects the temperature of the IGBT tube;

[0046] Collec...

Abstract

The invention discloses a cookware adaptive electromagnetic heating system, an electromagnetic heating device and a heating control method. The system comprises an electromagnetic heating control circuit and a main control chip. The electromagnetic heating control circuit comprises an IGBT tube, and the main control chip comprises a detection module, a temperature collection module, a calculationmodule, and an adjustment module. The detection module detects whether there is a pot or not. The temperature collection module collects the temperature of the IGBT tube when receiving a detection signal. The calculation module calculates the temperature change rate of the IGBT tube, and the adjustment module is connected with the calculation module, and adjusts the working state of the IGBT tubeaccording to the temperature change rate of the IGBT tube. According to the invention, the temperature change rate of the IGBT tube is collected through the temperature collection module, and the working state of the IGBT tube is adjusted according to the temperature change rate of the IGBT tube. The port is heated according to the set heating power, so that different pots can also achieve betterresults, and the system achieves the adaptive effect of the pots. The system is reliable, prolongs the product life, is better in user experience and enables the user to feel happy.

Description

technical field [0001] The invention relates to the field of electromagnetic heating, in particular to an adaptive electromagnetic heating system for cookware, an electromagnetic heating device, and a heating control method. Background technique [0002] At present, due to the variety of cookers on the market, each cooker will couple different inductance and impedance with the coil, resulting in changes in the resonance parameters of electromagnetic heating devices such as induction cookers or IH rice cookers, affecting the working status of induction cookers or IH rice cookers; Generally, the induction cooker will be equipped with pots when it leaves the factory, and the resonance parameters of the induction cooker are adjusted according to the pot. If other pots on the market are replaced, the resonance parameters will not match, which will affect the circuit performance and shorten the service life of the product. [0003] At present, in related technologies, the above-me...
