For described predetermined temperature change rate curve, as a example by cooking equipment is as microwave oven, when just beginning to warm up, food
The microwave energy that thing absorbs is little, and the rate of temperature change of food is the least, almost nil.Along with the increase of heat time heating time, food
Thing absorbs the speed of microwave energy and slowly accelerates, and rate of temperature change is big from little change simultaneously；After food temperature reaches certain value, inhale
The speed receiving energy can start slack-off, and its rate of temperature change the most just starts slowly to reduce from maximum；Along with food temperature gradually
During close to maximum (cooking food allows the maximum temperature reached), the speed of food absorption energy slowly reduces, variations in temperature
Rate is also reducing.Generally speaking, described predetermined temperature change curve reaction temperature rate of change becomes with changing from small to big heat time heating time again
Little process.
Described rate of temperature change curve compares with predetermined temperature change rate curve and can carry out in the following manner.Such as, exist
It is heated food and residing environment thereof the heated food targeted with the formulation of described predetermined temperature change rate curve and ring
In the case of border is identical, can be to determine that heated food is when this unit the unit time with a time quantum (such as, 5 seconds)
Between rate of temperature change, and temperature corresponding to this unit interval will become in this rate of temperature change and predetermined temperature change rate curve
Rate compares, such as, heating can start rate of temperature change and the predetermined temperature change rate curve temperature of first 5 seconds of first 5 seconds
Rate of change compares, and heating has started rate of temperature change and the predetermined temperature change rate curve 5-10 second of 5-10 second
Rate of temperature change compares.

Rate, then show that described temperature sensor has been likely to occur the heating components and parts of fault or cooking equipment and has broken down (such as,
Firepower is uncontrolled etc.), described food is only heated, to avoid accident to occur by the most controlled stop.
By this embodiment of the present invention, in the case of temperature sensor exists certain error, also can realize food and add
Being precisely controlled of heat, because in the case of the reading of temperature sensor is always below or above a certain value of correct reading, utilizing
This reading is still that the rate of temperature change that can accurately obtain heated food.It addition, temperature sensor exist fault or
Cooking equipment there are other components and parts faults and cause heats deviation intended in the case of (such as, it is impossible to thermometric or survey
Temperature result is disorderly), this embodiment of the present invention can find these problems in time by predetermined temperature rate of change, and controls to stop
Food to be heated is heated, it is to avoid security incident occurs.
