When opening the culinary art mode on electromagnetic oven, comprising the following steps:
User cooks mode by the membrane keyboard or key on the click electromagnetic oven or by voice selecting, while transmitting has
The wave source signal of fixed frequency.
When the frequency corresponding to the feedback signal is greater than the fixed frequency, then the electromagnetic oven is maintained to work normally
State；When the frequency corresponding to the feedback signal is equal to the fixed frequency, after first preset time period that is delayed, examine again
It surveys, if frequency corresponding to feedback signal is equal to the fixed frequency, controls the electromagnetic oven and stop working；If feedback signal
Corresponding frequency is greater than the fixed frequency, then maintains electromagnetic oven normal operating conditions.
The electromagnetic oven issues caution sound in first preset time period.
The detection zone is within the scope of electromagnetic oven centre distance 0.5m-10m.
The electromagnetic oven issues caution sound in first preset time period, to prompt user to return in time.First is pre-
If the period is 5s-30s, different culinary art modes can correspond to the different time, for example, in cooking mode or quick-fried mode,
First preset time period can be 5s；In barbecue mode, the first preset time period can be 1min;In French style, the
One preset time period can be 30s.It in other implementations, can also be comprehensive according to corresponding firepower size according to different culinary art modes
Close the first preset time period of setting.
Electromagnetic oven control method is realized by the correlation structure module of electromagnetic oven.As shown in Figure 1, a kind of electromagnetic oven, packet
