Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
See Fig. 1, this heating control device, the power module 5 comprising control panel, be electrically connected the well heater 2 of control panel and temperature sensing device 3 respectively and draw outward in control panel.Control panel is provided with microcontroller 1 and voltage changing module 4, and microcontroller 1 is set with associated control procedures, and the duty of FEEDBACK CONTROL well heater 2 according to associated control procedures and temperature sensing device 3.
Temperature sensing device 3 presets different point temperatures according to different phase, and according to the actual temperature in each stage and the relation of point temperatures, whether the work of control heater 2.Specific as follows:
Temperature sensing device 3 is preset with point temperatures C1, and at start advance trip temperature sensing, during sensing temperature C > C1, well heater 2 does not start work, otherwise starts working.
Temperature sensing device 3 is preset with point temperatures C2, after well heater 2 is started working, temperature sensing device 3 continues sensing temperature, during sensing temperature C < C2, well heater 2 stops the mode periodic duty of certain time interval T 2 with the certain time interval T 1 that works, until sensing temperature C > C2, well heater 2 recovers normal work.
The record of overheating when temperature sensing device 3 is preset with temperature rise definite value △ T and dry combustion method in schedule time T3, temperature sensing device 3 senses the temperature rise △ T1 that well heater 2 works in schedule time T3, if △ T1 >=△ is T, is then judged to be dry-fire condition, otherwise is judged to be normal condition.
Temperature sensing device 3 is preset with point temperatures C4, and in well heater 2 course of work, during sensing temperature C > C4, control heater 2 no longer works on.
If when temperature sensing device 3 is judged to be dry-fire condition, microcontroller 1 carries out carrying out lack of water prompting by bright light and/or alert ring at once; If again start well heater 2 after user adds water, temperature sensing device 3 sensing temperature again, as sensing temperature C > C4, well heater 2 does not start work, otherwise starts work.
