[0002] Microwave heating refers to a heating method that emits microwaves to food, allowing the food to absorb the microwave energy and convert it into heat energy, thereby increasing the overall temperature of the food itself. It has the characteristics of efficient, fast and uniform heating. As people's pace of life accelerates, microwave heating equipment is increasingly favored by consumers.

However, the method of adding cameras or infrared sensors will increase equipment costs and power consumption. The cameras or infrared sensors may also fail to function due to steam or oil stains in the equipment cavity, making the equipment less convenient. Summary of the Invention

[0054] like Figure 1 、 2 As shown, an embodiment of the present application provides a microwave device 100 , which includes a housing 110 , a microwave control device 120 and a solid-state source 130 disposed on the housing 110 , and a radiation component 140 disposed in an internal cavity of the housing 110 .

[0055] The microwave control device 120 is connected to the solid-state source 130 and the radiation component 140 respectively; the solid-state source 130 is connected to the radiation component 140 .

[0056] The microwave control device 120 is configured to generate a microwave generation instruction based on a preset initial frequency and a preset initial power, and transmit the instruction to the solid-state source 130 and the radiation component 140. Upon receiving the microwave generation instruction, the solid-state source 130 is configured to generate the corresponding microwave according to the preset initial frequency and power carried in the microwave generation instruction. Furthermore, upon receiving a stop generation instruction from the microwave control device 120, the radiation component 140 is configured to stop generating microwaves. The radiation component 140 is configured to frequency-modulate and phase-modulate the microwaves generated by the solid-state source 130 according to the preset initial frequency and power carried in the microwave generation instruction, and to radiate the frequency-modulated and phase-modulated microwaves into the internal cavity of the housing 110 to heat a target object placed within the internal cavity. Furthermore, the radiation component 140 is configured to collect the reflected power of the microwaves emitted by the radiation component 140 from the target object and transmit the reflected power to the microwave control device 120, so that the microwave control device 120 can determine the target position corresponding to the target object based on the reflected power.

[0057] The radiation assembly 140 is rotatable, and may be, for example, a rotatable antenna. The microwave control device 120 is further configured to generate a rotation command and transmit it to the radiation assembly 140. Upon receiving the rotation command, the radiation assembly 140 rotates by a preset angle. By adjusting the radiation angle of the radiation assembly 140, the microwave control device 120 can dynamically adjust the radiation direction of the radiation assembly 140, thereby adjusting the heating area of the radiation assembly 140.

[0058] The target object may be food to be heated that is placed in the internal cavity by a user.

[0059] It should be noted that the microwave device 100 may be a kitchen device that heats food using microwave heating, for example, a microwave oven, a microwave-bake-in-one, a microwave-steam-bake-in-one, etc.

[0060] The shell 110 is provided with an opening on which a door body is arranged; the shell 110 can be connected to one side of the door body through a hinge structure, so that the door body can rotate freely within a certain angle, and the shell 110 can use a door lock device to realize the opening and closing connection with the other side of the door body. When the shell 110 is connected to the other side of the door body, the opening on the shell 110 is closed, and the internal cavity of the shell 110 forms a sealed space. When the shell 110 is not connected to the other side of the door body, the opening on the shell 110 is open, and the user can place or take food in the internal cavity of the shell 110 through the open opening.

[0061] like Figure 2 As shown, the microwave control device 120 and the solid-state source 130 can be disposed adjacent to each other on the first end face of the housing 110, with the first end face being disposed opposite the opening of the housing 110. Specifically, the microwave control device 120 and the solid-state source 130 can be disposed on the outer surface of the first end face, and the microwave control device 120 and the solid-state source 130 can be pre-integrated into the same box.

[0062] like Figure 1 As shown, the radiation component 140 can be disposed on the second end surface of the housing 110, where the second end surface may refer to the upper end surface of the housing 110 in the height direction. The rotatable radiation component 140 can be disposed at the center of the second end surface of the housing 110, for example.

[0063] As an example, the microwave device 100 is further provided with a coaxial cable 150. Figure 1As shown, a through hole 111 may be provided on the first end face, one end of the coaxial cable 150 is connected to the radiation component 140 arranged on the second end face, and the other end of the coaxial cable 150 passes through the through hole 111 and is connected to the solid source 130 arranged on the outer surface of the first end face, thereby realizing the connection between the radiation component 140 and the solid source 130. The coaxial cable 150 is used to transmit the microwaves generated at the solid source 130 to the radiation component 140.

[0064] In one embodiment, the microwave device 100 may also be provided with a timing device. The timing device may, for example, be provided on the outer surface of the first end face and connected to the microwave control device 120. The timing device may start timing upon receiving a timing instruction from the microwave control device 120, and stop timing when the timing reaches the target duration corresponding to the timing instruction. The timing device also generates a stop instruction and sends it to the microwave control device 120. Upon receiving the stop instruction, the microwave control device 120 may generate a stop generation instruction and send it to the solid-state source 130 to control the solid-state source 130 to stop generating microwaves. The timing of the timing device may be used to indicate the duration of the solid-state source 130 to continuously generate microwaves, or may be used to indicate the duration of the microwave radiation of the radiation component 140.

[0065] In one embodiment, the microwave device 100 may also be provided with a weighing device. The weighing device may be provided, for example, on a third end face, which may be the lower end face of the housing 110 in the height direction, and the third end face is disposed opposite the second end face. The weighing device is connected to the microwave control device 120. In this embodiment, the food to be heated may be placed on the weighing device. The weighing device is used to weigh the food to be heated to obtain a corresponding weight parameter. The weighing device can then transmit the weight parameter to the microwave control device 120, so that the microwave control device 120 generates a target frequency and a target phase based on the weight parameter.

[0066] In one embodiment, a solid-state source microwave control method is provided. This embodiment uses the solid-state source microwave control method to be applied to a microwave control device in the above-mentioned microwave equipment as an example. Figure 3 As shown, the solid-state source microwave control method includes:

[0067] Step 302: In response to the microwave heating instruction, the radiation component of the microwave device is controlled to irradiate the target object with microwaves at different radiation angles according to the preset initial frequency and the preset initial power, and the reflected power of the target object at different radiation angles is collected to determine the target position corresponding to the target object.

[0068] The microwave heating instruction refers to an instruction to heat the food by subjecting the food to be heated to microwave radiation.

[0069] The microwave heating instruction may be issued by a user through a control panel pre-integrated on the microwave device. The control panel may be provided with a mechanical knob, a button, or a touch screen. The user issues the microwave heating instruction to the microwave control device by rotating the mechanical knob, pressing a button, or clicking a virtual button on the touch screen for indicating microwave heating. Alternatively, the microwave heating instruction may be automatically generated by the microwave control device. For example, when a user places food to be heated into the internal cavity of the microwave device, the weighing device may weigh the food to obtain a corresponding weight parameter. The weighing device may then send the weight parameter to the microwave control device. When the weight parameter reaches a preset weight threshold, the microwave control device automatically generates a microwave heating instruction.

[0070] In this embodiment, the microwave control device can generate corresponding microwave generation instructions according to a preset initial frequency and a preset initial power, and send them to the solid-state source and radiation component in the microwave equipment. The solid-state source generates corresponding microwaves according to the preset initial frequency and the preset initial power corresponding to the microwave generation instruction. The radiation component modulates the frequency and phase of the microwaves generated by the solid-state source according to the preset initial frequency and the preset initial power corresponding to the microwave generation instruction, and radiates them to the target object placed in the internal cavity of the microwave equipment to radiate microwaves to the target object.

[0071] Furthermore, a target object placed within the microwave device's internal cavity can absorb some microwaves and reflect the remainder. After receiving the reflected microwaves, the radiating component can transmit them to, for example, a power meter mounted on the microwave device to measure the reflected power of the microwaves. The power meter is connected to a microwave control device and can transmit the acquired reflected power to the microwave control device.

[0072] In microwave heating scenarios, smaller reflected power generally means that energy is more efficiently transmitted to the target object, that is, the target object absorbs more microwaves, which can be used as a basis for locating the target object.

[0073] The microwave equipment of this embodiment is provided with a rotatable radiation component, which can radiate microwaves to the target object at different radiation angles and collect the reflected power corresponding to each radiation angle. The microwave control device can sort the reflected power collected by the radiation component at different radiation angles in order from small to large, and select the heating area of the radiation angle corresponding to the minimum reflected power as the target position corresponding to the target object.

[0074] Step 304: Based on the radiation angle of the radiation component corresponding to the target position, control the radiation component to perform microwave heating on the target object at a preset heating power according to the target frequency.

[0075] The radiation angle of the radiation component corresponding to the target position can be understood as the angle with the best microwave heating effect on the target object.

[0076] It should be noted that the preset heating power is greater than the preset initial power. It can be understood that the microwave control device can control the radiation component to perform microwave radiation in step 302 at low power and control the radiation component to perform microwave heating in step 304 at high power.

[0077] The target frequency may be a preset heating frequency or an optimal absorption frequency of the target object.

[0078] The solid-state source microwave control method provided in the embodiment of the present application can, after receiving a microwave heating instruction, first use a rotatable radiation component to perform low-power microwave radiation on the target object according to different radiation angles, so that the target position can be quickly located by utilizing the reflected power at each radiation angle while consuming less power, thereby achieving precise microwave irradiation and heating of the target object according to the radiation angle corresponding to the target position. It can achieve rapid positioning and precise heating of the target object through microwave equipment with lower complexity, avoiding blind or excessive heating while improving the practicality of the microwave equipment.

[0079] In some optional embodiments, different radiation angles of the radiation component are pre-divided into corresponding heating areas;

[0080] Step 302 includes:

[0081] According to a preset initial frequency and with a preset initial power, the radiation component is controlled to radiate microwaves to the target object at different radiation angles, and the reflected power of the target object at different radiation angles is collected to determine the target radiation angle corresponding to the target object;

[0082] The target position is determined based on the heating area corresponding to the target radiation angle.

[0083] In this embodiment, the microwave control device can first generate a microwave generation instruction based on a preset initial frequency and a preset initial power and send it to the solid-state source and the radiation component. When the solid-state source receives the microwave generation instruction, it generates corresponding microwaves according to the preset initial frequency and the preset initial power carried by the microwave generation instruction; the radiation component frequency-modulates and phase-modulates the microwaves generated by the solid-state source according to the preset initial frequency and the preset initial power carried by the microwave generation instruction, and radiates the frequency-modulated and phase-modulated microwaves into the internal cavity of the shell at an initial radiation angle to perform microwave heating on the target object placed in the internal cavity; and collects the reflected power of the microwaves emitted by the radiation component from the target object, and sends the reflected power to the microwave control device. After receiving the reflected power received by the radiation component at the initial radiation angle, the microwave control device can generate a rotation instruction and send it to the radiation component. After receiving the rotation instruction, the radiation component can rotate to a preset angle. Then, the microwave control device again generates a microwave generation instruction based on the preset initial frequency and the preset initial power and sends it to the solid-state source and the radiation component to control the solid-state source to generate corresponding microwaves based on the preset initial frequency and the preset initial power, and controls the radiation component to frequency-modulate and phase-modulate the microwaves according to the preset initial frequency and the preset initial power, and then radiate the frequency-modulated and phase-modulated microwaves into the internal cavity of the shell at a new radiation angle... and so on.

[0084] The above-mentioned solid-state source microwave control method can find the optimal radiation angle of the radiation component for microwave heating of the target object by collecting the reflected power and adjusting the radiation angle of the radiation component, thereby ensuring that the microwave energy can be transmitted to the target object as effectively as possible, thereby improving the heating efficiency; and, by setting a rotatable radiation component, the number of radiation sources required for the microwave equipment can be significantly reduced, thereby reducing the manufacturing, installation and maintenance costs of the microwave equipment. This embodiment can achieve adjustment of the main heating area in the internal cavity of the microwave equipment through a single radiation component, making the microwave equipment more lightweight while realizing high intelligence of the microwave equipment.

[0085] In some optional embodiments, controlling the radiation component to irradiate the target object with microwaves at different radiation angles at a preset initial frequency and with a preset initial power, and collecting the reflected power of the target object at different radiation angles to determine the target radiation angle corresponding to the target object includes:

[0086] Controlling the radiation component to radiate microwaves to the target object at an initial radiation angle at a preset initial frequency and a preset initial power, and collecting the reflected power of the target object at the initial radiation angle;

[0087] When the reflected power reaches a preset reflected power threshold, the radiating component is controlled to rotate a preset angle, and the radiating component is controlled again to radiate microwaves to the target object at a preset initial power according to a preset initial frequency, and the reflected power of the target object at the current radiation angle is collected, and so on, until the new reflected power is less than the preset reflected power threshold;

[0088] The radiation angle of the radiation component at this time is used as the target radiation angle.

[0089] In this embodiment, the microwave control device can control the radiation component to radiate microwaves to the target object at an initial radiation angle according to a preset initial frequency and a preset initial power, and collect the reflected power of the target object. When the reflected power reaches a preset reflected power threshold, it can be considered that the microwaves radiated at the initial radiation angle are not absorbed in large quantities by the target object, that is, the position of the target object does not quite match the heating area corresponding to the initial radiation angle.

[0090] Furthermore, the microwave control device can control the radiation component to rotate to a preset angle, and again control the radiation component to radiate microwaves to the target object at a new radiation angle according to a preset initial frequency and a preset initial power, and collect the reflected power of the target object to determine whether the reflected power reaches a preset reflected power threshold. When the reflected power reaches the preset reflected power threshold, the radiation component is again controlled to rotate to a preset angle... and so on, until the reflected power is less than the preset reflected power threshold. At this time, it can be considered that the microwaves radiated at the new radiation angle can be absorbed in large quantities by the target object, that is, the position of the target object is more consistent with the heating area corresponding to the new radiation angle.

[0091] Furthermore, step 304 includes:

[0092] Controlling the radiation component to perform microwave heating on the target object at a target radiation angle according to a target frequency and a preset heating power;

[0093] The preset heating power is greater than the preset initial power.

[0094] In this embodiment, after collecting the reflected power, the microwave control device compares the reflected power with a preset reflected power threshold to determine in real time whether the microwaves radiated by the radiating component at the current radiation angle are substantially absorbed by the target object, thereby determining whether the target object is located within the heating zone corresponding to the current radiation angle. If so, the microwave control device directly generates a microwave generation instruction based on the target frequency and preset heating power and transmits it to the solid-state source and the radiating component. Upon receiving the microwave generation instruction, the solid-state source generates microwaves according to the target frequency and preset heating power carried in the microwave generation instruction. The radiating component frequency- and phase-modulates the microwaves generated by the solid-state source according to the target frequency and preset heating power carried in the microwave generation instruction, and radiates the frequency- and phase-modulated microwaves into the internal cavity of the housing at the current radiation angle, thereby heating the target object placed within the internal cavity. In this case, the radiating component does not need to adjust its position and can directly perform microwave heating according to the target frequency and preset heating power.

[0095] The above-mentioned solid-state source microwave control method can adjust the requirements for microwave absorption by the target object by adjusting the preset reflection power threshold, thereby achieving a balance between the speed of the angle adjustment process of the radiation component and the improvement of the microwave heating efficiency, while improving the angle adjustment speed and ensuring the microwave heating efficiency.

[0096] In some optional embodiments, controlling the radiation component to irradiate the target object with microwaves at different radiation angles at a preset initial frequency and with a preset initial power, and collecting the reflected power of the target object at different radiation angles to determine the target radiation angle corresponding to the target object includes:

[0097] Controlling the radiation component to radiate microwaves to the target object at an initial radiation angle at a preset initial frequency and a preset initial power, and collecting the reflected power of the target object at the initial radiation angle;

[0098] Controlling the radiation component to rotate to a preset angle, and controlling the radiation component again to radiate microwaves to the target object at a preset initial power according to a preset initial frequency, and collecting the reflected power of the target object at the current radiation angle, and so on, until the radiation component returns to the initial radiation angle;

[0099] The reflected powers of the target objects at different radiation angles are arranged in descending order, and the radiation angle corresponding to the minimum reflected power is taken as the target radiation angle.

[0100] As an example, Figure 3As shown, when the preset angle is 90°, the microwave control device can control the rotatable radiation component to rotate four times and then return to the initial radiation angle. During this process, the radiation component will perform microwave radiation four times and collect four reflected powers. The microwave control device can select the minimum reflected power from these four reflected powers and use the radiation angle corresponding to the minimum reflected power as the target radiation angle.

[0101] In this embodiment, after collecting the reflected power, the microwave control device generates a rotation instruction and sends it to the radiation component. After receiving the rotation instruction, the radiation component can rotate at a preset angle. Then, the microwave control device again generates a microwave generation instruction based on the preset initial frequency and the preset initial power and sends it to the solid-state source and the radiation component to control the solid-state source to generate corresponding microwaves based on the preset initial frequency and the preset initial power, and controls the radiation component to frequency-modulate and phase-modulate the microwaves according to the preset initial frequency and the preset initial power, and then radiate the frequency-modulated and phase-modulated microwaves into the internal cavity of the shell at a new radiation angle... and so on, until the radiation component returns to the position at the initial radiation angle.

[0102] The microwave control device can then select the minimum reflected power from the reflected powers collected in the above process, generate a rotation instruction, and send it to the radiating component. Upon receiving the rotation instruction, the radiating component can rotate until the radiation angle matches the radiation angle corresponding to the minimum reflected power. The microwave control device further generates a microwave generation instruction based on the target frequency and preset heating power and sends it to the solid-state source and the radiating component. Upon receiving the microwave generation instruction, the solid-state source can generate corresponding microwaves according to the target frequency and preset heating power contained in the microwave generation instruction. The radiating component frequency-modulates and phase-modulates the microwaves generated by the solid-state source according to the target frequency and preset heating power contained in the microwave generation instruction, and radiates the frequency-modulated and phase-modulated microwaves into the internal cavity of the shell at the current radiation angle to perform microwave heating on the target object placed in the internal cavity. The microwave control device can adjust the radiating component to the one with the best heating effect from multiple possible positions, control the radiating component to rotate until it reaches the position with the best heating effect, and then perform microwave heating according to the target frequency and preset heating power.

[0103] The above-mentioned solid-state source microwave control method can find the optimal radiation angle of the radiation component for microwave heating of the target object by collecting the reflected power and adjusting the radiation angle of the radiation component, thereby ensuring that the microwave energy can be transmitted to the target object as effectively as possible, thereby improving the heating efficiency; and, by setting a rotatable radiation component, the number of radiation sources required for the microwave equipment can be significantly reduced, thereby reducing the manufacturing, installation and maintenance costs of the microwave equipment. This embodiment can achieve adjustment of the main heating area in the internal cavity of the microwave equipment through a single radiation component, making the microwave equipment more lightweight while realizing high intelligence of the microwave equipment.

[0104] In some optional embodiments, the step of determining the target frequency includes:

[0105] According to the preset initial frequency range, the radiation component is controlled to perform sweep frequency radiation on the target object at the target radiation angle;

[0106] The reflected power of the target object at each frequency within the preset initial frequency range is collected to determine the target frequency corresponding to the target object.

[0107] It should be noted that the step of determining the target frequency may be set after step 302 and before step 304 .

[0108] In one embodiment, the step of collecting the reflected power of the target object at each frequency within a preset initial frequency range to determine the target frequency corresponding to the target object includes:

[0109] After completing the frequency sweep cycle, the reflected power of the target object at each frequency within the preset initial frequency range is collected, and the frequency corresponding to the minimum reflected power is screened out as the target frequency corresponding to the target object.

[0110] The target frequency can be understood as the current optimal absorption frequency of the target object.

[0111] In this embodiment, the microwave control device can subsequently increase the radiation power corresponding to the target frequency to a preset heating power, thereby achieving efficient heating.

[0112] In some optional embodiments, the solid-state source microwave control method further includes:

[0113] During the microwave heating process, according to a preset cycle, the radiation component is controlled to re-sweep the target object with radiation at a target radiation angle according to a preset initial frequency range and a preset initial power;

[0114] Recollecting the reflected power of the target object at each frequency within a preset frequency range;

[0115] The target frequency is updated according to the re-collected reflected power, so that the radiation component performs microwave heating on the target object at the target radiation angle according to the updated target frequency and the preset heating power.

[0116] In this embodiment, the microwave control device can continuously update the target frequency according to a preset period.

[0117] Typically, after a target object is subjected to microwave heating at a target frequency and a preset heating power for a period of time, the water content and temperature of the target object will change. At this time, the optimal absorption frequency of the target object will also change. If the radiation power of each frequency in the preset heating frequency range is continued to be regulated according to the initial target frequency, the microwave heating effect of the microwave equipment on the target object will deteriorate, resulting in uneven heating or inadequate heating.

[0118] The solid-state microwave control method can take into account changes in the moisture content and temperature of the target object after a period of heating, and by regularly retesting and adjusting the target frequency, ensure that the target frequency always matches the target's optimal absorption frequency, thereby continuously optimizing heating efficiency.

[0119] It should be noted that, in step 306, the heating may be stopped when the microwave heating meets the preset requirements.

[0120] The preset requirement refers to a condition for instructing the microwave device to stop microwave heating.

[0121] As an example, the preset requirement may be that the radiation time of the radiation component reaches the target time corresponding to the microwave heating instruction, which can be understood as the microwave heating time of the microwave equipment reaching the target time. The target time can be selected by the user on the control panel. For example, the mechanical knob on the control panel can correspond to several heating times, the button can correspond to several heating times, and the touch screen can be pre-integrated with virtual buttons indicating multiple heating times. The user sends a microwave heating instruction carrying the target time information to the microwave control device by rotating the mechanical knob to the target time, pressing the button corresponding to the target time, or clicking the virtual button used to represent the target time on the touch screen.

[0122] After receiving the microwave heating instruction carrying the target duration information, the microwave control device can generate a timing instruction carrying the target duration information and send it to the timing device of the microwave equipment, so that the timing device starts timing, and at the same time controls the solid-state source to generate microwaves and controls the radiation component to radiate the target object according to the preset initial frequency, preset initial phase and preset initial power to determine the target position of the target object. Then the microwave control device controls the radiation component to perform microwave heating on the target object according to the corresponding target phase, target frequency and preset heating power. When the timing reaches the target duration, the timing device stops timing and generates a stop instruction to send to the microwave control device. At this time, the microwave control device can determine that the microwave heating process meets the preset requirements, and can further generate a stop generation instruction after receiving the stop instruction and send it to the solid-state source to control the solid-state source to stop generating microwaves and stop microwave heating of the target object.

[0123] The solid-state source microwave control method of this embodiment can re-determine the optimal absorption frequency of the target object according to a preset cycle to prevent the target object from changing its state due to changes in temperature and moisture content. This enables the microwave equipment to adjust the microwave emission strategy according to the preset cycle, thereby improving the accuracy and efficiency of microwave heating, and thus enabling customized microwave heating treatment of the target object.

[0124] In one embodiment, the reflected power used in any of the above embodiments can be replaced by microwave reflectivity.

[0125] Microwave reflectivity can be calculated based on reflected power using the following formula:

[0126] in, represents the microwave reflectivity, represents the power of the microwaves radiated by the radiation component. In step 304, To preset the initial power, in step 306, It is the preset heating power; Indicates the reflected power of the target object collected by the radiation component.
