The control method of the anti-dry of above-mentioned detachable electric steamer, mainly comprises the steps:
A. the choosing of thermistor and fuse:
During choosing value, the temperature value that thermistor 10 is experienced need be greater than 80 DEG C, judges water by accident and open when avoiding standby, and the dry combustion method protection temperature value of thermistor 10 correspondence is 145 ± 5 DEG C, is preferably 145 DEG C; The temperature value of fuse 11 is preferably 216 DEG C;
B. heat:
B1: the temperature value that thermistor 10 twice reading is corresponding is equal, is judged to be that water is opened;
B2: in thermistor 10 liang of seconds, corresponding temperature value difference is less than 2 DEG C, is judged to be that water is opened;
After boiled 10 points of water, power is adjusted to 1/2 to 2/3 heating of peak power;
C. heating is interrupted:
If the temperature of thermistor 10 correspondence reaches or do not reach 145 DEG C higher than 130 DEG C, stop heating 10-15 second, be preferably 12 seconds, then continue heating;
D. anti-dry protection:
If the temperature value of thermistor 10 correspondence is more than 145 ± 5 DEG C, is preferably 145 DEG C, carries out dry combustion method protection, namely cut off heater circuit.
The method not only can guarantee the dry combustion method protection of interior pot 4, and can guarantee the not molten dish of heat-generating disc 6, reaches and gos deep into use temperature-sensing probe the same protected effect that heat-generating disc directly measures heat-generating disc temperature.For heat-generating disc 6 for 1300W: process to boil water (in pot filled with water, by the common voltage of 1.15 times, from normal temperature to water is boiled) is tested in temperature rise, and the temperature value of thermistor 10 correspondence is 120 DEG C-130 DEG C, and fuse 11 position temperature value is 130 DEG C.For considering pot distortion in the later stage, the dry combustion method protection temperature value selecting thermistor 10 correspondence is 145 ± 5 DEG C.
