Abstract

The invention relates to a method for controllable gradient heating of multiple temperature zones. The method comprises the following steps: (1) generating a pulse width modulation waveform PWM by anMCU (Microprogrammed Control Unit), and starting heating; (2) acquiring a heating start signal and a temperature shift signal by the MCU, and finely classifying PWM adjustment shifts; (3) measuring areal-time temperature of a heating device by the MCU, and adjusting an output duty ratio of the PWM according to a temperature interval mode of the real-time temperature of the heating device and a former temperature value measured by the MCU till a set temperature of temperature shifts is met, and keeping the temperature; (4) judging whether a preset overall heating time is met or not, if the preset overall heating time is met, stopping heating, if the preset overall heating time is not met, judging whether a preset temperature detection time is met or not, if the preset temperature detectiontime is met, detecting a present real-time temperature, updating the present real-time temperature, and repeating the step (3) according to the updated present real-time temperature, and if the preset temperature detection time is not met, waiting till the preset temperature detection time is met, and detecting the present real-time temperature.

Description

technical field [0001] The invention relates to the technical field of heat exchange, in particular to a multi-temperature-zone controllable gradient heating method. Background technique [0002] In the heating process of various existing heating devices, the part that touches the skin at the beginning will rise to its set temperature value within a certain period of time, and because the existing equipment basically adopts a substrate with high thermal conductivity, in the early stage of equipment use Because the temperature is lower than the normal body temperature, it will bring a cold and tingling sensation. After the heating temperature of the equipment exceeds the human skin temperature, the human body will have an unbearable burning sensation due to the rapid heating rate, especially for children's skin somatosensory. ; and the general heating device is made of stainless steel in contact with human skin, and the low temperature of the metal will be obviously felt at t...
