Wherein the first preset time is 24-36 seconds, such as 30 seconds; the second preset time is 4-6 seconds, such as 5 seconds; the first preset rotating speed is 1-3 r/min, such as 2 r/min; the second preset rotating speed is 15-25 r/min, such as 20 r/min; the preset power is 8-12W, such as 10W.
Specifically, as shown in fig. 4, it is determined whether a heated object is heated unevenly every 30 seconds, and the adjustment times of the heating power and the fan rotation speed are cleared, if there is an uneven heating problem, the rotation speed of the tray is first controlled to be reduced by 2 rpm to improve the microwave capability and accelerate the temperature rise, then the temperature rise rate is determined every 5 seconds, if the temperature rise rate is greater than a first preset rate (which may be a fixed value), the fan rotation speed is controlled to be increased by 20 rpm, if the temperature rise rate is less than or equal to the first preset rate, the heating power of the heating device is controlled to be reduced by 10 watts, when the next 5 seconds arrive, the heating rate is adjusted once again, and after the total adjustment times reaches 6 times, the adjustment times are cleared again to determine whether the heated unevenly.

When the rotation speed Vmax is reduced in the accumulated rotation speed, the rotation speed of the tray is not controlled to be reduced even if the uneven heating of the heated object is judged again.
For easy understanding, a control method of a microwave oven according to an embodiment of the present invention will be described with reference to fig. 5;
as shown in fig. 5, when the microwave oven starts heating the heat receiving object, the tray loaded with the heat receiving object starts to rotate, and each infrared detection head starts to perform temperature detection. Judging whether the heated object is heated unevenly or not according to the temperature detected by each infrared detection head, and if the heated object is judged to be heated unevenly, adjusting the rotating speed of the tray, the heating power of the heating device and the rotating speed of the fan; if the heated object is judged to have no uneven heating condition, executing a normal microwave heating program; until heating is complete.
The control method of the microwave oven of the embodiment detects the temperature of the heated object through the plurality of infrared detection heads to judge whether the heated object is heated unevenly, and then adjusts the rotating speed of the tray, the rotating speed of the fan and the power of the heating device when the heated object is heated unevenly, so that the heating efficiency of the heating device can be improved, the overall power consumption is reduced, and meanwhile, the heated object can be heated evenly like food, so that the color and the taste of the food can be improved.
