Microcomputer is controlled thawing of the 1st stage according to time of calculating and the electromotive power output set; Finish after the 1st stage, control thawing of the 2nd stage according to time of having set and the electromotive power output set; Finish the control of thawing in the 1st stage and the 2nd stage, the warning tones that will sound and set for switching process.
Thaw after the beginning, when the warning tones that sounds, user's thing that thaws that will overturn.Finish after the switching process, microcomputer is just controlled the course of defrosting in the 3rd stage and the 4th stage, continues to finish the course of defrosting of the thing that thaws that had overturn.
Among all thawing times, the 1st stage must be than higher with the output power level set in the 3rd stage.The output power level in the 3rd stage is lower than the 1st stage, but relative with the 4th stage higher compared with the 2nd stage.This be because thaw in the early stage open when making and upset after when beginning to thaw, need thaw with higher output power level control.
In the unfreezing control method of micro-wave oven, when beginning to thaw when thawing beginning in the early stage and after the upset, thaw with higher electromotive power output control.But in the unfreezing control method of microwave current stove, also undertaken by said process for the situation of having omitted switching process, the control of thawing is irrelevant with switching process.For the thing that thaws that has omitted switching process, can cause excessively and thaw.
Also have a kind of for upset situation and not have the situation of upset to adopt the defreezing method of the different algorithms that thaws respectively, this method is being omitted under the situation of overturning, and has solved that some parts excessively thaws or burned problem, but thawing time is still long.
Summary of the invention
For solving the problem that exists in the above-mentioned technology, the purpose of this invention is to provide a kind of unfreezing control method of micro-wave oven, adopt two kinds of thermals source that thaw, reach desirable defrost result, improved thawing rate.
For realizing goal of the invention, the technical solution used in the present invention provides a kind of unfreezing control method of micro-wave oven, and this method includes following steps:
Phase I at first selects thawed foodstuff to thaw, and opens two thermals source---microwave and hot blast when thawing; Then divide four-stage, there is identical period T in each stage;
Microwave and hot air convection fan are opened simultaneously, and heating tube work is closed behind microwave operation a period of time t1, closes behind convection current barbecue tube work a period of time t2;
Second stage is only opened microwave, closes behind microwave operation a period of time t3;
Phase III is only opened microwave, closes behind microwave operation a period of time t4;
The quadravalence section is only opened microwave work, closes behind microwave operation a period of time t5;
Five-stage is only opened microwave, and microwave operation a period of time t6 closes afterwards;
According to the difference of thawed foodstuff, the adjustment that the above-mentioned stage of thawing is increased and decreased.
Described five-stage microwave t6 running time is 5 seconds.
Described one to the five-stage the hot air convection fan be duty.
It is 30 seconds that there is identical period T in described each stage.
The effect that the present invention reaches has solved some things parts of thawing and has excessively thawed or burned problem, because by two kinds of thermals source that thaw, thereby has improved ideal effect to food thawing, has improved thawing rate.
