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 radio frequency signal to scan the cooking cavity.
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.).
Here, the transmitted rf signal is used to scan the cooking cavity to obtain the material of the cooking utensil, so the rf energy corresponding to the rf signal used may be a range of rf frequency less than that required for normal cooking.
Optionally, in this embodiment, controlling the rf module to emit the rf signal to scan the cooking cavity includes: determining a preset frequency range of the radio frequency signal according to the volume of the cooking cavity; and controlling the radio frequency module to continuously transmit radio frequency signals within a preset frequency range to the cooking cavity.
In the embodiment, the radio frequency module is controlled to emit radio frequency signals with the frequency range of 2400MHz-2500MHz to continuously and uniformly scan the cooking cavity.
Step S302, the processor obtains the radio frequency signal reflected by the cooking cavity, and determines the material of the cooking utensil in the cooking cavity according to the reflected radio frequency signal.
The rf module transmits rf signals, a portion of which is absorbed by food and the other portion of which is absorbed or reflected by the cooking container, so that the material of the corresponding cooking appliance can be determined by monitoring the reflected rf signals (unabsorbed electromagnetic waves).
Optionally, determining the material of the cooking utensil in the cooking cavity according to the reflected radio frequency signal includes: obtaining a current power difference of the reflected radio frequency signal and the transmitted radio frequency signal; and determining the material of the corresponding cooking utensil according to the current power difference.
The corresponding relationship between the power difference between the transmitted signal and the reflected signal and the material of the cooking utensil can be obtained through a test mode, for example, under the condition that the same quality and form of food are subjected to radio frequency heating under the same cooking instruction, the power difference between the radio frequency signal transmitted by the radio frequency module and the received reflected radio frequency signal is recorded when the cooking utensils are used in the same size and are different in material, and therefore the corresponding relationship between the power difference and the material of the cooking utensil is determined.
And after the corresponding relation is obtained, the material of the cooking appliance corresponding to the current power difference value is obtained by calling the corresponding relation so as to determine the operation scheme of the radio frequency cooking equipment. Further, the corresponding relationship may be pre-stored in the processor in the form of a corresponding information table.
In step S303, the processor executes a corresponding cooking mode according to the material of the cooking appliance.
Thus, according to the control method for the radio frequency cooking device provided by the embodiment of the disclosure, the radio frequency module of the radio frequency cooking device is controlled to emit a series of radio frequency signals to scan the cooking cavity, one part of the emitted radio frequency signals is absorbed and consumed, the other part of the emitted radio frequency signals is reflected back, and the material of the cooking appliance is determined according to the analysis result of the reflected radio frequency signals, so as to execute the corresponding cooking program. Therefore, heat loss caused by materials of the cooking appliance in the radio frequency heating mode can be compensated, and the heating efficiency of the cooking equipment is improved.
Optionally, obtaining a current power difference of the reflected radio frequency signal and the transmitted radio frequency signal comprises: obtaining a radio frequency signal power loss value corresponding to the cooking instruction; and determining the difference between the power value of the transmitted radio frequency signal and the power loss value of the radio frequency signal and the power value of the reflected radio frequency signal as the current power difference.
And the radio frequency signal power loss value is used for representing the radio frequency signal power absorbed by the food after the radio frequency signal is sent out under the current cooking instruction. Generally, the value of the numerical value is related to the cooking mode and the food material type.
In this embodiment, obtaining the rf signal power loss value corresponding to the cooking command includes: and acquiring the to-be-cooked recipe information corresponding to the cooking instruction so as to determine the corresponding radio frequency signal power loss value.
Here, the recipe information to be cooked at least includes food material type information, so as to determine a corresponding radio frequency signal power loss value according to the recipe information to be cooked. The corresponding relationship between the food material type information and the radio frequency signal power loss value can be obtained through experiments. For example, under the same cooking instruction, when different types of food with the same quality and shape are subjected to radio frequency heating, the radio frequency energy absorption rates (i.e., the ratio of the power loss value to the transmitted radio frequency signal) of the different types of food are recorded, so that the power loss values under the different food materials and the different radio frequency signals are determined according to the corresponding relationship between the radio frequency energy absorption rates and the food material types.
The corresponding relation between the radio frequency energy absorption rate and the food material types is pre-stored in the processor, after the recipe information to be cooked corresponding to the cooking instruction is obtained, the corresponding relation is called, the radio frequency energy absorption rate corresponding to the current recipe to be cooked is further obtained, the radio frequency signal power loss value is determined according to the transmitted radio frequency signal and the radio frequency energy absorption rate, the current power difference value is further determined according to the difference value between the transmitted radio frequency signal power value and the radio frequency signal power loss value and the difference value between the reflected radio frequency signal power values, the material of the cooking appliance corresponding to the current power difference value is further determined, and the operation scheme of the radio frequency cooking equipment is determined. Further, the corresponding relationship may be pre-stored in the processor in the form of a corresponding information table.
Optionally, determining a material of the corresponding cooking appliance according to the current power difference includes: under the condition that the current power difference value is smaller than the preset value, the cooking utensil is made of metal; and under the condition that the current power difference value is greater than or equal to the preset value, the cooking utensil is made of a non-metal material.
Generally, microwaves are substantially totally reflected on a metal surface; and non-metal materials such as ceramics, glass and the like have certain microwave transmission characteristics, so that the material of the cooking utensil in the cooking cavity can be detected through the value of basic parameters (such as amplitude attenuation, phase shift amount or frequency and the like) of the power difference between the transmitted radio frequency signal and the reflected radio frequency signal. Identifying the cooking utensil corresponding to the condition that the power difference value between the transmitted radio frequency signal and the received and reflected radio frequency signal is small as a metal material; and identifying the cooking utensil corresponding to the condition that the power difference value between the transmitted radio frequency signal and the received and reflected radio frequency signal is large as a non-metal material.
Here, the preset value is used to indicate a case where the power difference is small, that is, a case where the reflectivity of the rf wave of the detected cooking appliance is high and the parameter difference between the incident wave and the reflected wave is small. When a radio frequency signal is incident to a conductive medium (metal material), most energy is reflected, and a small part of energy enters the metal under the influence of a skin effect, so that a smaller power difference is formed. In this embodiment, since there is food to be heated (load) and a part of the rf signal is absorbed, the preset value should be set to be larger than the power loss value caused by skin effect.
Therefore, according to the embodiment of the disclosure, the radio frequency module of the radio frequency cooking device is controlled to emit a series of radio frequency signals to scan the cooking cavity, one part of the emitted radio frequency signals is absorbed and consumed, the other part of the emitted radio frequency signals is reflected, and the cooking utensil is determined to be made of a metal material or a non-metal material according to the analysis result of the reflected radio frequency signals so as to execute the corresponding cooking program.
Fig. 4 is a schematic diagram of a control method for an rf cooking apparatus, which is applied to the environment shown in fig. 2, and may be executed in the rf cooking apparatus shown in fig. 2, or executed in a control terminal of the rf cooking apparatus, for example, an operation panel; the method can also be executed in a server, such as a family cloud platform which is communicated with the radio frequency cooking equipment; the method can also be executed in terminal equipment, such as a control terminal of a smart phone, a smart household appliance or a smart furniture system. 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 rf module to transmit an rf signal to scan the cooking cavity.
Step S402, the processor obtains the radio frequency signals reflected by the cooking cavity, and determines the material of the cooking utensil in the cooking cavity according to the reflected radio frequency signals.
Step S403, the processor increases the radio frequency signal power corresponding to the cooking instruction by a first increment under the condition that the cooking utensil is made of metal; under the condition that the cooking utensil is made of a non-metal material, the radio frequency signal power corresponding to the cooking instruction is increased by a second increment; wherein the first increase is greater than the second increase.
Here, through when cooking utensil is different materials, set up different increments for the many radio frequency signals that correspond of cooking instruction, realize the compensation to the heat loss that radio frequency heating in-process, the cooking utensil that does not hold the material leads to.
Specifically, since the reflectivity of the metal material is high, a high power increment is set for the cooking mode when the cooking appliance is made of the metal material, and the power of the radio frequency signal can be increased by increasing the frequency of the radio frequency signal, increasing the amplitude of the radio frequency signal and the like, so as to improve the heating efficiency in the radio frequency heating mode. A relatively low power increment is set for the cooking mode when the cooking utensil is made of non-metal materials so as to properly compensate the heat loss caused by the cooking utensil.
The compensation for heat loss in the rf heating mode may further include, because of different sizes and thicknesses of cooking utensils, the heat loss that may be generated is different: acquiring the temperature change rate of the food material within a set time length in the cooking process; and adjusting the numerical value of the first increment or the second increment according to the temperature change rate of the food material.
Here, the temperature change of the food material at each stage in the cooking process may be saved in the recipe information to be cooked. For example, the temperature change rate set by the food material in the set time length of the preheating stage, the temperature change rate set by the food material in the set time length of the coloring stage, etc. The corresponding relation between the cooking stage and the temperature change rate of the food materials is prestored in recipe information, after a corresponding recipe to be cooked is called in response to a cooking instruction, the temperature change rate of the food materials within a set time length in the cooking process is obtained, the corresponding relation is called, the set temperature change rate of the food materials in the current cooking stage is further obtained, and the value of a first increment or a second increment is adjusted according to the size relation between the detected temperature change rate of the food materials and the set temperature change rate of the food materials.
Specifically, in the case that the detected temperature change rate of the food material is higher than the set temperature change rate, decreasing the value of the first increase amount or the second increase amount; and under the condition that the detected temperature change rate of the food material is smaller than the set temperature change rate, increasing the numerical value of the first increment or the second increment.
Therefore, the embodiment of the disclosure transmits a series of radio frequency signals to scan the cooking cavity by controlling the radio frequency module of the radio frequency cooking device, determines the material of the cooking utensil to be a metal material or a non-metal material according to the analysis result of the reflected radio frequency signals, and executes a corresponding cooking program to realize the compensation of heat loss caused by the cooking utensil which is not compatible with the material in the radio frequency heating process; and the power of the radio frequency signal can be adjusted in real time according to the temperature change condition of the food materials in the heating process, so that the heating efficiency of the radio frequency cooking equipment is ensured.
