Specifically, at least two RF microwave sources 12 emit microwaves into the cavity 10 in a plurality of scanning heating modes, so as to screen which scanning heating mode is more suitable for heating food in the cavity 10 based on the plurality of scanning reflected power. The plurality of scanning reflected powers may be different in phase, frequency, or both. It should be noted that, taking the example that the microwave cooking apparatus 100 includes two rf microwave sources 12, the scanning heating mode may include a frequency and a phase difference between the two rf microwave sources 12, and the scanning heating mode may also include a frequency and a phase corresponding to the two rf microwave sources 12, which is not limited in this application.

It should be noted that, when controlling at least two rf microwave sources 12 to emit microwaves into the cavity 10 in the scan heating mode, the at least two rf microwave sources 12 may emit microwaves together to obtain scan reflected power, or the at least two rf microwave sources 12 may emit microwaves in batches to obtain scan reflected power. Specifically, taking the example that the microwave cooking apparatus 100 includes two rf microwave sources 12, the two rf microwave sources 12 may be controlled to emit microwaves into the cavity 10 together in the scanning heating mode, or one rf microwave source 12 may be controlled to emit microwaves into the cavity 10 in the scanning heating mode, and then the other rf microwave source 12 may be controlled to emit microwaves into the cavity 10 in the scanning heating mode.
In some embodiments, the first zone heating mode has a frequency within a first frequency range and the second zone heating mode has a frequency within a second frequency range, the first frequency range and the second frequency range not overlapping.
Therefore, the partition heating can be realized, and the first partition heating mode and the second partition heating mode are different.
Specifically, when screening a plurality of scanning heating modes to obtain a first partition heating mode, screening the plurality of scanning heating modes, and selecting the first partition heating mode from the scanning heating modes in the first frequency range; similarly, when the plurality of scanning heating modes are screened to obtain the second partition heating mode, the plurality of scanning heating modes can be screened first, and the second partition heating mode is selected from the scanning heating modes in the second frequency range.
In a certain embodiment, the first frequency range may be 2400 MHz-2450 MHz, and the second frequency range may be 2450 MHz-2500 MHz; in another embodiment, the first frequency range may be 2400 MHz-2420 MHz, and the second frequency range may be 2480 MHz-2500 MHz, which is not specifically mentioned in the present application.
Further, the phase of the first zone heating mode is within a first phase range and the phase of the second zone heating mode is within a second phase range, the first and second phase ranges not overlapping or at least partially overlapping.
Therefore, the phase of the first partition heating mode and the phase of the second partition heating mode can be limited, and a good partition heating effect is ensured.
Specifically, the first partition heating mode may be selected from the scanning heating modes located in the first phase range, and similarly, the second partition heating mode may be selected from the scanning heating modes located in the second phase range. There are a number of specific values for the first phase range and the second phase range, for example, in some embodiments the first phase range may be 0 deg. to 90 deg., and the second phase range may be 50 deg. to 180 deg.. As another example, in another embodiment, the first phase range may be 0 ° to 90 °, and the second phase range may be 100 ° to 180 °.
In certain embodiments, the first preset condition comprises at least one of:
the duration of the microwave emission into the cavity 10 by the at least two rf microwave sources 12 exceeds a first time threshold;
the difference between the transmitted power and the reflected power of the microwaves emitted by the at least two rf microwave sources 12 into the cavity 10 exceeds a first power threshold.
Thus, a basis can be provided for updating the first zone heating mode and/or the second zone heating mode.
Specifically, the condition that the first preset condition is satisfied may be understood that the state of the food in the cavity 10 is changed, and the first partition heating mode and/or the second partition heating mode need to be readjusted, and it may be understood that the required heating mode is changed when the food in the cavity 10 is at different temperatures and different states, so that the first partition heating mode and/or the second partition heating mode are updated in time, so that a better heating effect can be achieved, and the use experience of a user is improved.
It should be noted that, when the first preset condition is satisfied, the first partition heating mode may be the same as the second partition heating mode, or when the first preset condition is satisfied, the first partition heating mode may be updated, or when the first preset condition is satisfied, the second partition heating mode may be updated.
The difference between the transmission power and the reflection power of the microwaves emitted by the at least two rf microwave sources 12 into the cavity 10 can be used to express the power absorbed by the food in the cavity 10, and the first power threshold can be adjusted according to the energy required for cooking the food, the type of food, and the like, which is not particularly limited in this application.
The first preset condition may include that a time period during which the at least two rf microwave sources 12 transmit microwaves into the cavity 10 exceeds a first time threshold, the first preset condition may further include that a difference between a transmission power of the at least two rf microwave sources 12 transmit microwaves into the cavity 10 and a reflection power exceeds a first power threshold, the first preset condition may further include that a time period during which the at least two rf microwave sources 12 transmit microwaves into the cavity 10 exceeds the first time threshold and that a difference between a transmission power of the at least two rf microwave sources 12 transmit microwaves into the cavity 10 and a reflection power exceeds the first power threshold.
It will be appreciated that the first time threshold may be set by the manufacturer, and the first time threshold may also be set by the user, which is not particularly limited in this application. The first power threshold may be set by the manufacturer, or the first power threshold may be set by the user, which is not specifically limited in this application. In other embodiments, the first preset condition may also include the temperature of the food within the cavity 10.
It should be noted that, in some embodiments, the first preset condition may include a first sub-condition and a second sub-condition, where the first zone heating mode is updated when the rf microwave source 12 corresponding to the first zone heating mode satisfies the first sub-condition, and the second zone heating mode is updated when the rf microwave source 12 corresponding to the second zone heating mode satisfies the second sub-condition. The first sub-condition and the second sub-condition may be the same or different.
In some embodiments, referring to fig. 3, the control method includes:
step 022, when the second preset condition is satisfied, controls all the rf microwave sources 12 to stop emitting microwaves.
The control method of the microwave cooking appliance 100 of the embodiment of the present application may be implemented by the microwave cooking appliance 100 of the embodiment of the present application. Specifically, the controller 16 is configured to control all the rf microwave sources 12 to stop emitting microwaves when the second preset condition is satisfied.
In this way, the radio frequency microwave source 12 can be stopped from emitting microwaves in time, and overheating of food in the cavity 10 is avoided.
Specifically, when the second preset condition is satisfied, it can be considered that the food in the microwave oven has not been heated.
Further, the second preset condition includes at least one of:
the duration of the microwave emission into the cavity 10 by the at least two rf microwave sources 12 exceeds a second time threshold;
the difference between the transmission power and the reflected power of the microwaves transmitted by the at least two rf microwave sources 12 into the cavity 10 exceeds a second power threshold;
the number of times the first preset condition is satisfied exceeds a number of times threshold.
In this way, it is possible to provide a basis for stopping the emission of microwaves by the rf microwave source 12.
Specifically, the second time threshold may be set by a manufacturer, for example, the manufacturer sets the longest cooking time of the microwave cooking appliance 100, so as to avoid overheating of the microwave cooking appliance 100; the second time threshold may also be set by a user, for example, the user may set the heating duration, and the second time threshold may also be updated after sale. The second power threshold may be set by the manufacturer, and the second power threshold may also be set by the user, which is not specifically limited in this application.
Specific values of the frequency threshold may be 1, 2, 3, and 3 or more times, which are not particularly limited in this application.
In some embodiments, the second preset condition includes a third sub-condition and a fourth sub-condition, and when the rf microwave source 12 corresponding to the first heating mode satisfies the third sub-condition, the rf microwave source 12 corresponding to the first heating mode is controlled to stop emitting microwaves, and when the rf microwave source 12 corresponding to the second heating mode satisfies the fourth sub-condition, the rf microwave source 12 corresponding to the second heating mode is controlled to stop emitting microwaves. The third sub-condition and the fourth sub-condition may be the same or different.
In certain embodiments, the preset power is less than or equal to 100 watts.
In this way, it is possible to avoid a large influence on the food in the cavity 10 during the process of acquiring the corresponding plurality of scanning reflected powers.
Specifically, at least two rf microwave sources 12 are controlled to emit microwaves into the cavity 10 in a preset power in a plurality of scanning heating modes, so as to obtain corresponding scanning reflected power, and under the condition that the preset power is too high, the state of food in the cavity 10 is greatly affected, so that a larger error may occur in the scanning reflected power obtained later, and user experience is reduced. Therefore, the preset power is less than or equal to 100 watts, so that overlarge errors of the corresponding multiple scanning reflected powers are avoided, and the influence on food in the process of acquiring the multiple scanning reflected powers is reduced.
