Temperature control method and device for electromagnetic heating and electromagnetic heating equipment

Abstract

The invention provides a temperature control method and device for electromagnetic heating and electromagnetic heating equipment. The temperature control method for electromagnetic heating comprises the following steps: acquiring a set heating temperature; carrying out heating by adopting first preset power; acquiring a current first heating temperature; calculating a first temperature difference value between the set heating temperature and the first heating temperature; if the first temperature difference value is greater than a first threshold of a plurality of pre-configured thresholds, carrying out heating by adopting first power corresponding to the first threshold, and executing the steps of acquiring the first temperature difference value and carrying out heating by adopting the first power again, and until the first temperature difference value is smaller than a second threshold in the plurality of thresholds, stopping heating. According to the temperature control method for electromagnetic heating, which is provided by the invention, accuracy of temperature control in the electromagnetic heating process can be promoted, temperature deviation is reduced, and heating time is shortened.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a temperature control method and device for electromagnetic heating and electromagnetic heating equipment. Background technique [0002] Induction cooker is a common household appliance. In daily life, an induction cooker is used to heat equipment such as pots or kettles placed on the induction cooker for food processing or boiling water. [0003] When using the induction cooker to heat, the user sets the temperature or temperature level through the buttons on the ceramic panel, and the induction cooker uses the preset power for heating. During the heating process, the induction cooker needs to detect the temperature of the pot or kettle through the ceramic panel. When the temperature of the pot or kettle reaches the set temperature, the induction cooker stops heating. Afterwards, if the temperature is lower than a certain threshold value, the preset power will be...

AI Technical Summary

Problems solved by technology

However, the temperature of the pot or kettle detected by the induction cooker across the ceramic panel will be biased

If the preset power is large, it will cause a relatively large temperature deviation

For example, the temperature of the pot or kettle detected by the induction cooker across the ceramic panel has reached the set temperature, but the actual temperature of the pot or kettle may have been greater than the set temperature

During the time interval between when the actual temperature of the pot or kettle reaches the set temperature and when the induction cooker detects that the temperature of the pot or kettle reaches the set temperature, due to the large preset power, the temperature deviation is relatively large

If the preset power is small, heating with a smaller preset power will result in a longer heating time when reaching the set temperature

[0004] It can be seen that controlling the temperature through the above method makes the temperature deviation larger or the heating time longer
