In the embodiments of the present disclosure, the description is made with a processor of the radio frequency cooking apparatus as an execution subject.

Step S301, responding to the cooking instruction, the processor controls the radio frequency module to emit a first electromagnetic wave signal.

Here, the cooking instruction may be an instruction issued by a user, or an instruction issued when the radio frequency cooking device determines that the radio frequency cooking device is suitable for operation.

In some application scenarios, the radio frequency cooking device may obtain the cooking instruction according to a voice instruction of a user; or obtaining the cooking instruction through the operation intention of the user, such as: keys, touch screens, knobs, switches on and off doors, set gestures, and the like. The radio frequency cooking equipment can also obtain a cooking instruction issued by a user through an application program of the smart phone through communication with the smart phone.

Here, the cooking instructions may include general heating instructions and specific cooking mode instructions (food cooking plans including cooking recipes, such as cake broiling, chicken broilers, lamb chops, etc.).

The radio frequency module emits a first electromagnetic wave signal according to a cooking instruction so as to realize heating and cooking of food; in other embodiments, the first electromagnetic wave signal may be used for field intensity confirmation before cooking starts, and the rf energy corresponding to the rf signal used in this case may be in a range of rf frequency smaller than that required for normal cooking.

Optionally, in this embodiment, controlling the radio frequency module to emit the first electromagnetic wave signal includes: determining a preset frequency range of the first electromagnetic wave signal according to the volume of the cooking cavity; and controlling the radio frequency module to continuously transmit a first electromagnetic wave signal within a preset frequency range to the cooking cavity.

In this embodiment, the frequency range of the first electromagnetic wave signal is 2400MHz-2500MHz.

In step S302, the processor controls the detection module to emit a second electromagnetic wave signal to scan the cooking cavity, and superimposes the second electromagnetic wave signal on the electromagnetic field formed by the first electromagnetic wave signal.

Here, the cooking cavity is scanned by emitting the second electromagnetic wave signal, so that the field intensity distribution condition of each area in the cooking cavity is obtained according to the superposition result of the second electromagnetic wave signal and the first electromagnetic wave signal.

The detection module comprises a transmitter and a receiver, and is arranged on the side wall of the radio frequency cooking equipment so as to transmit a second electromagnetic wave signal for detecting the standing wave field intensity and receive a reflected signal of the second electromagnetic wave.

Optionally, controlling the detection module to emit a second electromagnetic wave signal includes: and controlling the detection module to transmit a second electromagnetic wave signal while the radio frequency module transmits the first electromagnetic wave. The field intensity distribution condition in the cooking cavity is obtained through the first electromagnetic wave and the second electromagnetic wave, the parameter setting process of the radio frequency cooking equipment can be shortened, and the cooking efficiency is improved to a certain extent.

In some embodiments, controlling the detection module to emit the second electromagnetic wave signal may also include: and after the radio frequency module transmits the first electromagnetic wave signal for a set time interval, controlling the detection module to transmit a second electromagnetic wave signal. By emitting the second electromagnetic wave signal after the set time interval t1, the field intensity detection is performed after the electromagnetic field (standing wave field) formed by the first electromagnetic wave is stabilized, and the accuracy of the detection result can be improved.

Optionally, the frequency of the first electromagnetic wave signal is the same as the frequency of the second electromagnetic wave signal. In other embodiments of the present scheme, it may also be defined that the power of the first electromagnetic wave signal is equal to the power of the second electromagnetic wave signal; or the phase of the first electromagnetic wave signal is the same as the phase of the second electromagnetic wave signal; or the amplitude of the first electromagnetic wave signal is equal to the amplitude of the second electromagnetic wave signal. By emitting the second electromagnetic wave signal with the same emission parameter as the first electromagnetic wave signal, the electromagnetic resonance effect is good, the influence degree of the signal by the parameter of the signal is low, and the accuracy of the detection result can be improved.

Step S303, the processor determines the transmission parameter of the radio frequency module according to the reflection signal of the second electromagnetic wave signal received by the detection module.

By adopting the control method for the radio frequency cooking equipment provided by the embodiment of the disclosure, the electromagnetic field formed by the second electromagnetic wave sent by the detection module and the first electromagnetic wave in the cooking cavity is superposed to cause resonance, so that the electromagnetic wave reflection signal received by the detection module is changed. The electromagnetic field intensity distribution condition in the cooking cavity can be obtained by detecting and analyzing the reflected signal of the second electromagnetic wave sent by the detection module. And then can be according to the electromagnetic wave transmission of this field intensity distribution situation intelligent control radio frequency module to the realization is to the regulation of culinary art efficiency, improves the homogeneity of culinary art.

Optionally, the controlling the transmission parameter of the radio frequency module according to the reflected signal of the second electromagnetic wave signal received by the detection module includes:

determining the field intensity distribution condition in the cooking cavity according to the reflected signals;

and determining the emission parameters of the radio frequency module according to the field intensity distribution condition of the electromagnetic field.

The field intensity distribution condition refers to the field intensity parameters or power distribution condition of a plurality of areas in the cooking cavity. In an electromagnetic field, the strength of the field is often related to the distance of transmission of the electromagnetic signal. In the cooking cavity, due to the change of transmission routes of signal refraction, reflection and the like, the intensity of the electromagnetic field formed by the signal is also uneven and uncertain.

Here, by acquiring a reflected signal after the second electromagnetic signal is superimposed on the electromagnetic field formed by the first electromagnetic signal, the field intensity distribution within the cooking intensity can be obtained. For the area with stronger field intensity, the emission parameters of the radio frequency module corresponding to the area can be reduced; for the area with weaker field intensity, the emission parameters of the radio frequency module corresponding to the area can be improved.

Wherein, the field intensity distribution condition in the cooking cavity is determined by the following method:

obtaining a relative field intensity parameter of the current scanning position according to the reflection signal of the current scanning position;

and determining the field intensity distribution condition in the cooking cavity according to the relative field intensity parameters of the plurality of scanning positions.

The corresponding relationship between the relative field strength parameter and the reflected signal can be obtained through a test mode. For example, in an ideal state, an electromagnetic wave signal is emitted in a space of a stable set field strength, and the correspondence between different field strengths, different electromagnetic wave parameters (frequency, amplitude, phase, etc.) and reflection values of the obtained electromagnetic wave signal is recorded.

And pre-storing the corresponding relation between the relative field intensity parameters and the reflected signals in a storage medium, and obtaining the relative field intensity parameters corresponding to the reflected signal parameters of the current scanning position by calling the corresponding relation when the reflected signals of the current scanning position are obtained, so as to be used for determining the field intensity distribution condition of the cooking cavity.

Specifically, obtaining the relative field strength parameter of the current scanning bit according to the reflection signal of the current scanning bit includes:

and obtaining the relative field intensity parameter of the current scanning position according to the amplitude of the electromagnetic resonance signal in the reflected signal of the current scanning position.

Here, according to the characteristics of the electromagnetic field (standing wave field) formed by the first electromagnetic wave in the cooking cavity, the amplitudes of the incident signal and the reflected signal are stable and unchanged, so that the relative field strength parameter of the current scanning position can be determined by acquiring the amplitude of the electromagnetic resonance signal in the reflected signal.

For example, the amplitude of the electromagnetic resonance signal in the reflected signal of the current scanning position is obtained, and the field strength parameter corresponding to the amplitude of the current electromagnetic resonance signal is determined as the relative field strength parameter of the current scanning position in the corresponding relationship between the relative field strength parameter and the reflected signal.

Further, the amplitude of the electromagnetic resonance signal is in positive correlation with the relative field strength parameter. The larger the amplitude of the electromagnetic resonance signal is, the more severe the electromagnetic resonance caused by the superposition of the second electromagnetic signal on the electromagnetic field formed by the first electromagnetic signal is, and thus the field strength value of the scanning bit is relatively higher. In other embodiments, the relative field strength parameter of the current scanning position can also be determined by the parameters of the frequency, the phase and the like of the electromagnetic resonance signal in the reflected signal of the current scanning position.

By adopting the control method for the radio frequency cooking equipment provided by the embodiment of the disclosure, the electromagnetic field formed by the second electromagnetic wave sent by the detection module and the first electromagnetic wave in the cooking cavity is superposed to cause resonance, so that the electromagnetic wave reflection signal received by the detection module is changed. The electromagnetic field intensity distribution condition in the cooking cavity can be obtained by detecting and analyzing the reflected signal of the second electromagnetic wave sent by the detection module. And then can be according to the electromagnetic wave transmission of this field intensity distribution situation intelligent control radio frequency module to the realization is to the regulation of culinary art efficiency, improves the homogeneity of culinary art.

In the embodiments of the present disclosure, the description is made with the processor of the radio frequency cooking apparatus as the execution subject.

In step S401, in response to the cooking instruction, the processor controls the radio frequency module to emit a first electromagnetic wave signal.

In step S402, the processor controls the detection module to emit a second electromagnetic wave signal to scan the cooking cavity, and superimposes the second electromagnetic wave signal on the electromagnetic field formed by the first electromagnetic wave signal.

In step S403, the processor obtains electromagnetic resonance intensities of a plurality of regions in the cooking cavity according to the reflected signal of the second electromagnetic wave signal received by the detection module.

In step S404, the processor determines the region where the electromagnetic resonance intensity is greater than the set value as a load region, and controls the rf module to increase the rf signal transmission density or frequency to the load region.

Here, the loading zone refers to an area where food is located. Generally, the resonance signal of the area is strong and the absorption to the resonance frequency is high, so that the cooking efficiency of the radio frequency cooking device can be improved by increasing the radio frequency signal emission density or the emission frequency of the area.

Further, obtaining the electromagnetic resonance intensity of the plurality of regions in the cooking cavity may include obtaining one or more parameters of frequency, power, amplitude, and phase of the electromagnetic resonance signal of the plurality of regions. The higher the frequency, power, and amplitude of the electromagnetic resonance signal, the wider the phase, and the higher the corresponding electromagnetic resonance intensity.

And then can be according to the electromagnetic wave transmission of this field intensity distribution situation intelligent control radio frequency module to realize the regulation to culinary art efficiency, improve the homogeneity of culinary art.
