After heating starts, open the cooling fan that heating is outdoor, make the homogeneous temperature that heating is indoor, with reduce freezing meat stuffing is carried out temperature detection time appearance error, such as, press after heat button in 10 seconds, only allow cooling fan and infrared ray sensor action, and obtain this in 10 seconds the output voltage of infrared ray sensor be Vs as minima.If Vs is more than certain numerical value, then it is judged to heating object non-frozen product and stops heating and send information etc., thus preventing user mistake from using.
The output voltage and the time that record infrared sensor to the meat stuffing of 200g and 400g time in the present invention by being heated thawing obtain curve chart as shown in Figure 6. In Fig. 6,16a is the curve chart of heating defrosting 400g meat stuffing, and 16b is the curve chart of heating defrosting 200g meat stuffing. As shown in Figure 6,200g meat stuffing being heated the output voltage of infrared sensor when thawing, comparison 40g meat stuffing is heated the output voltage of infrared sensor when thawing to be changed faster.
In an embodiment of the present invention, the food of known different components is respectively heated defrosting, and respectively obtain the 4th detected value of temperature sensor output in the 4th detected value of food temperature sensor output in the 3rd given time section of different component and the 4th given time section, determine the component coefficient corresponding from each known different components according to the time difference between the 3rd detected value, the 4th detected value and the 3rd given time Duan Yu tetra-given time section, calculate the relation between component and component coefficient. Detailed process is as follows:
Fig. 7 is the labor figure that the meat stuffing to 200g and 400g is heated the voltage output of infrared sensor when thawing. Generally when being heated thawing, in order to prevent the situation of heating uneven or local excessive heating, the heating unit such as magnetron can open or close with both fixed cycles, namely stops certain time after heating given time, then at heating given time, repeats this process. In embodiment as shown in Figure 7, magnetron heats 9 seconds, then stops 20 seconds, repeat this process after stopping 20 seconds after heating 9 seconds. For the noise preventing the heating of the heating units such as magnetron from temperature acquisition being caused, embodiments of the invention stop gathering in 20 seconds of heating the temperature of meat stuffing at magnetron, to obtain the relation between defrosting component and component coefficient according to the sensor output voltage gathered. By obtaining following relational expression M=A �� k+B (formula 1) after mass data is detected and calculated, M represents that component, A, B represent constant coefficient, and K represents component coefficient.
In one embodiment of the invention, have employed the non-action of the 3rd of on-off action and the 5th circulation meansigma methods in 20 seconds. Its reason is, as it is shown in fig. 7, the output voltage plots changes of temperature sensor becomes apparent from relatively within this time period. According to the 3rd and the 5th meansigma methods that cycle detection is obtained, can ask for according to following formula and try to achieve slope (i.e. k):

V1; (output voltage average value in the OFF time of the 3rd circulation)
V2; (output voltage average value in the OFF time of the 5th circulation)
Due to, the difference comparsion of voltage is little, is multiplied by 100 as its slope to conveniently calculate and comparing in embodiments of the invention.
As it is shown in fig. 7,200g meat stuffing is 1.063V at the average voltage of the 3rd circulation, the average voltage of the 5th circulation is 1.118V. 400g meat stuffing is 1.025V at the average voltage of the 3rd circulation, and the average voltage of the 5th circulation is 1.062V. The k calculated when can obtain 400g meat stuffing is heated defrosting by above-mentioned formula 1 is: 1.062-1.025) �� 100/58=0.06. Equally possible k 200g meat stuffing being heated when thawing that obtains is: (1.118-1.063) �� 100/58=0.09.In order to facilitate computing, and k can be taken advantage of 100 by the computing capability of processor etc. in actual operation. Now, being-66.7 according to the computed A obtained of formula 1, B is 800. Therefore, formula 1 can be expressed as M=-66.7 �� k+800.
In one embodiment of the invention, the above-mentioned basis determining component records its heat time heating time and component by the food of different components is heated defrosting, the relation of defrosting component and heat time heating time as follows can be obtained, T=M �� X+Y (formula 2), wherein, T represents the heat time heating time to defrosting food, and M represents the component treating defrosting food, and X, Y are constant coefficient. In an embodiment of the present invention, in order to reduce error reduction noise, it is possible to adopt above-mentioned result of calculation to go the modes such as meansigma methods.
In one embodiment of the invention, time difference between first given time section and heating start-up time, and the 3rd the time difference between given time section and heating start-up time match, and the time difference that second between given time section and heating start-up time, and the time difference between the 4th given time section and heating start-up time matches. Such as, the time period adopted when determining the relation between component and component coefficient in the above-described embodiments is the 3rd and the 5th circulation, then determining that the time period gathered when defrosting food is heated and thawing also is the time period in the 3rd and the 5th circulation treated when defrosting food is heated defrosting. By when determining the relation between component and component coefficient and treat when defrosting food is heated solving and adopt time period of matching to can ensure that effectiveness and the concordance of data such that it is able to thaw exactly.
In one embodiment of the invention, after the relation determined between different component and component coefficient k, as long as heating afterwards determines that component coefficient k just can obtain the component to thaw in thawing, such that it is able to determine heat time heating time according to formula 2, to be heated defrosting food thawing.
In one embodiment of the invention, treat when defrosting food is heated thawing and obtain the output voltage treating defrosting food infrared sensor in the out-of-work multiple intervals of magnetron, and the average voltage obtaining in each interval and the time difference of test point corresponding to connected average voltage will be calculated. Passable in order to reduce amount of calculation, and accuracy, carry out the interval detected with above-mentioned determine component coefficient k time detection interval identical. Such as detection the 3rd, the 5th circulation etc., it is possible to collection interval during by the relation determined between different component and component coefficient k is determined. Obtained the variable quantity of output voltage by the output voltage of infrared sensor and time, namely obtain component coefficient k, in order to the value value of k can be as above k*100 by convenient calculating. Thus, through type 1 can obtain defrosting component, is further advanced by formula 2 and obtains heat time heating time, such that it is able to defrosting food is heated defrosting control.
