So that the manner in which the above recited aspects, features and advantages of the present invention can be understood in detail, a more particular description of the invention, briefly summarized above, may be had by reference to the embodiments thereof which are illustrated in the appended drawings. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the scope of the present invention is not limited by the specific embodiments disclosed below.

step 102, receiving control information;

104, sending control information to a plurality of microwave sources, wherein the control information comprises the working modes of the microwave sources; under the condition that the working mode is the same-frequency running mode, the plurality of microwave sources inject microwaves with the same frequency into the working cavity.

The application provides a control method of a heating device, and the control of a plurality of microwave sources can be realized by operating the control method. In the process, the plurality of microwave sources output microwaves with the same frequency, so that different hot spot distribution areas can be formed in the working cavity, and the food materials in the working cavity have a better microwave absorption effect in the hot spot distribution areas. Compared with the related embodiment, the microwave absorption effect of the food material is enhanced, and correspondingly, the heating effect of the food material is also enhanced, so that the microwave heating efficiency is improved.

Specifically, the operation mode is contained in the transmitted control information in a limited manner, so that after the microwave source receives the control information, the current operation mode can be known by using the control information, and thus, the plurality of microwave sources can inject microwaves with the same frequency into the operation cavity.

In the above embodiment, the same-frequency operation mode may be understood that the frequencies of the microwaves output by the plurality of microwave sources are the same, where the same frequency may be understood as the same frequency value, or may immediately be similar frequency values, for example, a ratio of a difference between a first microwave frequency at a first sampling time and a second microwave frequency at a second sampling time to the first microwave frequency is less than or equal to a preset value. The preset value can be selected according to the actual use scene, such as 1%, 3%, and the like.

In the process, the working modes are divided for the microwave sources so as to realize the synchronous control of the plurality of microwave sources, so that the plurality of microwave sources can output microwaves with the same frequency, and the probability of the condition that the microwaves output by different microwave sources are inconsistent is reduced.

In one embodiment, the control information is generated when a certain function of the heating device is selected. For example, the "heat" function is selected.

For another example, in the case that the function of "fast heating" is selected, the control information whose operation mode is the same-frequency operation mode is generated.

In the above embodiment, different microwave sources are communicatively connected, and each microwave source includes a microwave generating source and an amplifying circuit; under the same-frequency operation mode, controlling a microwave generation source of a first microwave source to generate a radio frequency signal, and sending the radio frequency signal to an amplifying circuit of the first microwave source and a microwave generation source of a second microwave source so that the amplifying circuit of the first microwave source and the amplifying circuit of the second microwave source can output microwaves; the first microwave source and the second microwave source are any two microwave sources in the plurality of microwave sources.

In this embodiment, it is difficult to ensure that the microwaves output by the plurality of microwave sources have the same frequency, since the different microwave sources are independent of each other and there is no data interaction between the different microwave sources.

In order to realize that the frequencies of the microwaves output by the plurality of microwave sources are the same, the embodiments of the present application specifically define a communication connection between different microwave sources so as to realize data interaction between different microwave sources. Specifically, a microwave generation source of a first microwave source is used for generating radio frequency signals, and the radio frequency signals are forwarded to other microwave sources based on communication connection relations among different microwave sources, so that the other microwave sources amplify the received radio frequency signals.

Specifically, a microwave generating source in the first microwave source generates a radio frequency signal, and transmits the radio frequency signal to an amplifying circuit of the first microwave source, so that the amplifying circuit of the first microwave source amplifies the received radio frequency signal, thereby outputting microwaves; for the second microwave source, the microwave generating source of the second microwave source does not generate the radio frequency signal, but receives the radio frequency signal sent by the microwave generating source of the first microwave source, and transmits the radio frequency signal to the amplifying circuit of the second microwave source, so that the amplifying circuit of the second microwave source amplifies the received radio frequency signal, and the microwave is output.

In one embodiment, in the case that the number of the second microwave sources is multiple, the microwave generating sources of each second microwave source are in communication connection with each other so as to realize retransmission of radio frequency signals, and ensure that multiple microwave sources can output microwaves with the same frequency.

In one embodiment, in the case that the number of the second microwave sources is multiple, the microwave generating source of each second microwave source is in communication connection with the microwave generating source of the first microwave source, so as to realize the retransmission between the radio frequency signals and ensure that the multiple microwave sources can output microwaves with the same frequency.

In one embodiment, the microwave generating source is a device that generates a radio frequency signal. The amplifying circuit, that is, the device or the circuit structure for amplifying the radio frequency signal, may amplify the received radio frequency signal, and it can be understood that only the amplitude of the signal is different between the radio frequency signal before amplification and the microwave output after amplification, and specifically, the amplitude of the signal of the radio frequency signal before amplification is smaller than the amplitude of the microwave output after amplification.

In this embodiment, by defining that the control information further includes a phase offset value, in the same-frequency operation mode, the phase offset value in the control information is used to superimpose the initial phase of the radio frequency signal, so as to obtain the operation phase under the current microwave source, so that different microwave sources output microwaves with different phases. In the process, the phase difference can be generated when the microwaves among different microwave sources are fed into the working cavity, so that the microwave distribution in the working cavity can be adjusted, and a foundation is provided for ensuring the microwave absorption effect of food materials in the working cavity.

Specifically, for example, when the initial phase is 0, the phase offset value in the control information of the first microwave source is 0 °, the phase offset value in the control information of the second microwave source is 5 °, the phase offset value in the control information of the third microwave source is 10 °, and accordingly, the operating phase of the first microwave source is 0, the operating phase of the second microwave source is 5 °, and the operating phase of the third microwave source is 10 °, so that the microwave formed in the working chamber has a plurality of distribution hot spots.

In any of the above embodiments, based on the operating mode being the independent operating mode, the microwave generation source in the third microwave source generates a radio frequency signal and sends the radio frequency signal to the amplifying circuit, so that the amplifying circuit outputs microwaves; wherein the third microwave source is any one of a plurality of microwave sources.

In the embodiment, a plurality of microwave sources can be limited to operate in a same-frequency operation mode and can also operate in an independent operation mode, and in the independent operation mode, different microwave sources independently work so as to meet the use requirements in different scenes.

Specifically, the microwave sources of the heating device operate in an independent operation mode under the condition that the volume of the food materials put in is small, and in the process, a user can control the starting number of the microwave sources according to actual use requirements, for example, a proper microwave source is started for heating, and other microwave sources can be stopped from operating, so that the service life of the microwave sources is prolonged.

In any of the above embodiments, the control information further comprises an operating power of each microwave source.

In this embodiment, the operation power of each microwave source during operation is contained in the control information so as to meet the actual use requirement. Specifically, in the process of amplifying the radio frequency signal by the amplifying circuit, the operating power of the microwave source is obtained, and the amplitude of the amplified microwave is determined according to the operating power.

In any of the above embodiments, the control information further includes switching information for each microwave source, wherein the switching information is used to instruct the microwave source to start running and end running.
