Description

Technical Field

[0001] This invention relates to the field of control technology, and more specifically, to a cooking device and its control method, apparatus, and readable storage medium. Background Technology

[0002] Microwave heating is characterized by its high heating efficiency and has gradually become a commonly used heating technology in household appliances. Microwave heating involves feeding microwaves into a cooking cavity through a microwave device, using the action of microwaves on the food to achieve heating.

[0003] In the relevant technical solutions, regardless of the type of food being heated, the microwave device outputs the same microwaves to the cooking cavity. Although there are control schemes that use a stirring blade to disperse the microwaves or a turntable to rotate the food to improve the uniformity of heating, the above schemes cannot maintain the same uniformity of heating for different foods. That is, when heating the same food (such as cake), although various efforts (stirring blade, turntable) can make it heat evenly, the same heating effect cannot be replicated when heating another food (such as beef) under the same conditions. Summary of the Invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0005] Therefore, a first aspect of the present invention is to provide a method for controlling a cooking device.

[0006] A second aspect of the present invention is that a control device for a cooking apparatus is provided.

[0007] A third aspect of the invention is that it provides a control device for another cooking apparatus.

[0008] A fourth aspect of the present invention is that a readable storage medium is provided.

[0009] A fifth aspect of the present invention is that a cooking apparatus is provided.

[0010] In view of the above, according to a first aspect of the present invention, the present invention provides a control method for a cooking apparatus, the cooking apparatus including a cooking cavity and a microwave device for feeding microwaves into the cooking cavity, the control method comprising: controlling the microwave device to output a first microwave to determine a target frequency phase combination among a plurality of frequency phase combinations, wherein the frequency and initial phase of the first microwave are switched among the plurality of frequency phase combinations; and controlling the microwave device to output a second microwave based on the target frequency phase combination; wherein the power of the second microwave is greater than the power of the first microwave.

[0011] The technical solution of this invention proposes a control method for cooking equipment. By running this control method, the uniformity of heating different ingredients can be improved, thereby ensuring the heating effect.

[0012] Specifically, the microwaves output by the microwave device create heating hotspots at certain locations within the cooking cavity. Food at these hotspots heats up quickly, while food at non-hotspot locations heats up slowly. The location of the heating hotspots also varies depending on the food. Based on this, a first microwave is emitted to serve as a scanning microwave. The frequency and initial phase of this scanning microwave continuously switch between multiple pre-set frequency-phase combinations to find the target frequency-phase combination suitable for heating the current food. This target frequency-phase combination ensures uniform heating, and high-power heating is performed based on this target combination. During this process, the frequency and initial phase of the microwaves output by the microwave device are controlled to improve the uniformity of food heating.

[0013] In addition, the control method for the cooking equipment proposed in this invention also has the following additional technical features.

[0014] In the above technical solution, there are at least two sets of target frequency phase combinations, and the frequency output by the microwave device varies within a preset frequency range. The preset frequency range includes at least two frequency intervals, and the at least two sets of target frequency phase combinations correspond to at least two frequency intervals.

[0015] In the above technical solution, each frequency range corresponds to a set of target frequency phase combinations, and each set of target frequency phase combinations includes at least one frequency phase combination. Based on this, when outputting the second microwave based on the target frequency phase combination, the heating hotspots in the cooking cavity also switch when different target frequency phase combinations are switched. Combining the frequency phase combinations corresponding to different frequency ranges, a heating matrix composed of heating hotspots can be formed in the cooking cavity. Under the heating of this heating matrix, the food will be heated evenly, thereby improving the heating effect.

[0016] In any of the above technical solutions, within each frequency range, the microwave device is controlled to output a first microwave to determine a target frequency phase combination among multiple frequency phase combinations. Specifically, this includes: controlling the microwave device to output a first microwave, the power of which is a first power; determining a third microwave reflected within the cooking cavity, the power of which is a second power; and determining the target frequency phase combination based on the first power and the second power.

[0017] In this technical solution, microwave heating uses microwaves to heat food. Therefore, it is desirable for the food to absorb as much microwave as possible, that is, for the temperature to rise as quickly as possible. Based on this, microwaves inside the cooking cavity, i.e., the third microwave, can be collected and the power of the third microwave can be compared with the power of the first microwave to determine how much of the microwave generated by the microwave device has been absorbed by the food. Based on this, the target frequency phase combination can be selected from multiple frequency phase combinations to ensure both heating uniformity and heating efficiency.

[0018] In one of the technical solutions, the target frequency phase combination is determined based on the first power and the second power, specifically including: determining the standing wave ratio (SWR) of each frequency phase combination based on the first power and the second power; and determining the target frequency phase combination based on the SWR.

[0019] In this technical solution, the concept of standing wave ratio (VSWR) is introduced as a screening condition for multiple frequency phase combinations. Specifically, VSWR = (1 + reflection coefficient magnitude) / (1 - reflection coefficient magnitude), where the reflection coefficient magnitude is the ratio of the second power to the first power. Based on this, the target frequency phase combination can be screened by the magnitude of the VSWR.

[0020] In one of the technical solutions, the target frequency phase combination is determined based on the standing wave ratio (SWR). Specifically, this includes: sorting the SWR of each frequency phase combination from smallest to largest to obtain a sorting sequence; and taking the frequency phase combinations corresponding to the top N SWRs in the sorting sequence as the target frequency phase combination; where N is a positive integer greater than or equal to 1.

[0021] In this technical solution, the standing wave ratio (SWR) can characterize the heating efficiency. Specifically, the smaller the SWR, the higher the heating efficiency, and vice versa. Using the SWR, multiple frequency phase combinations are sorted to obtain the sorting sequence as described above. Based on the number of frequency phase combinations contained in each target frequency phase combination, i.e., N mentioned above, the N frequency phase combinations corresponding to the top SWRs in the sorting sequence are selected to obtain the target frequency phase combination.

[0022] In this process, the heating efficiency of the food is improved by sorting the target frequency phase combinations to obtain the highest heating efficiency.

[0023] One of the technical solutions also includes: obtaining the duration of the second microwave output by the microwave device; and controlling the microwave device to stop operating based on the duration being greater than or equal to the first duration.

[0024] In this technical solution, by recording the duration of the second microwave continuous output, i.e. the continuous duration mentioned above, the microwave device is controlled to stop operating when the continuous duration reaches the first duration. In this process, the probability of damage to the microwave device due to prolonged operation can be avoided, and the food located at the heating hot spot can be prevented from being heated for a long time and thus becoming burnt.

[0025] In addition, the first duration can be used as the end condition for a single heating cycle, dividing the heating of the food into multiple heating cycles. That is, after continuously outputting the second microwave for the first duration, the microwave device stops running for one duration, then restarts and outputs the second microwave based on the target frequency phase combination.

[0026] One of the technical solutions also includes: periodically updating the target frequency phase combination; and controlling the microwave device to output a second microwave based on the updated target frequency phase combination.

[0027] In this technical solution, after the food is heated by microwaves, the temperature of the food itself will rise, and its ability to absorb microwaves will change. By periodically updating the target frequency phase combination, the microwave device can dynamically adjust the output of the second microwave according to the actual situation of the food being cooked, so as to further improve the uniformity of food cooking and reduce the problem of uneven food temperature.

[0028] One of the technical solutions also includes: acquiring the cumulative duration of the second microwave output by the microwave device; controlling the microwave device to stop operating based on the cumulative duration being greater than or equal to the second duration; wherein the second duration is greater than or equal to the first duration.

[0029] In this technical solution, the second time limit can be understood as the total cooking time required for the food. It can be set by the user. By controlling the microwave device to stop operating when the cumulative cooking time exceeds the second time limit, the cooking of the food can be automatically completed.

[0030] One of the technical solutions also includes: acquiring information about the type of food being cooked; and determining the power of the second microwave based on the type information.

[0031] In this technical solution, by acquiring information about the type of food being cooked, the power of the second microwave can be guided by this information, thereby improving the matching degree between the food being cooked and the power of the second microwave. This reduces the chance of the food being burned due to excessive cooking power, and also reduces the occurrence of situations where the food cannot achieve the desired cooking effect due to insufficient cooking power.

[0032] According to a second aspect of the present invention, the present invention provides a control device for a cooking apparatus, the cooking apparatus including a cooking cavity and a microwave device for feeding microwaves into the cooking cavity, the control device comprising: a determining unit for controlling the microwave device to output a first microwave to determine a target frequency phase combination among a plurality of frequency phase combinations, wherein the frequency and initial phase of the first microwave are switched among the plurality of frequency phase combinations; and a control unit for controlling the microwave device to output a second microwave based on the target frequency phase combination; wherein the power of the second microwave is greater than the power of the first microwave.

[0033] The technical solution of the present invention proposes a control device for cooking equipment, which can improve the uniformity of heating different ingredients, thereby ensuring the heating effect.

[0034] Specifically, the microwaves output by the microwave device create heating hotspots at certain locations within the cooking cavity. Food at these hotspots heats up quickly, while food at non-hotspot locations heats up slowly. The location of the heating hotspots also varies depending on the food. Based on this, a first microwave is emitted to serve as a scanning microwave. The frequency and initial phase of this scanning microwave continuously switch between multiple pre-set frequency-phase combinations to find the target frequency-phase combination suitable for heating the current food. This target frequency-phase combination ensures uniform heating, and high-power heating is performed based on this target combination. During this process, the frequency and initial phase of the microwaves output by the microwave device are controlled to improve the uniformity of food heating.

[0035] In addition, the control device for the cooking equipment proposed in this invention also has the following additional technical features.

[0036] In the above technical solution, there are at least two sets of target frequency phase combinations, and the frequency output by the microwave device varies within a preset frequency range. The preset frequency range includes at least two frequency intervals, and the at least two sets of target frequency phase combinations correspond to at least two frequency intervals.

[0037] In the above technical solution, each frequency range corresponds to a set of target frequency phase combinations, and each set of target frequency phase combinations includes at least one frequency phase combination. Based on this, when outputting the second microwave based on the target frequency phase combination, the heating hotspots in the cooking cavity also switch when different target frequency phase combinations are switched. Combining the frequency phase combinations corresponding to different frequency ranges, a heating matrix composed of heating hotspots can be formed in the cooking cavity. Under the heating of this heating matrix, the food will be heated evenly, thereby improving the heating effect.

[0038] In any of the above technical solutions, within each frequency range, a unit is defined, specifically for: controlling the microwave device to output a first microwave, the power of which is a first power; determining a third microwave reflected within the cooking cavity, the power of which is a second power; and determining a target frequency phase combination based on the first power and the second power.

[0039] In this technical solution, microwave heating uses microwaves to heat food. Therefore, it is desirable for the food to absorb as much microwave as possible, that is, for the temperature to rise as quickly as possible. Based on this, microwaves inside the cooking cavity, i.e., the third microwave, can be collected and the power of the third microwave can be compared with the power of the first microwave to determine how much of the microwave generated by the microwave device has been absorbed by the food. Based on this, the target frequency phase combination can be selected from multiple frequency phase combinations to ensure both heating uniformity and heating efficiency.

[0040] In one of the technical solutions, the determining unit is specifically used to: determine the standing wave ratio (SWR) of each frequency phase combination based on the first power and the second power; and determine the target frequency phase combination based on the SWR.

[0041] In this technical solution, the concept of standing wave ratio (VSWR) is introduced as a screening condition for multiple frequency phase combinations. Specifically, VSWR = (1 + reflection coefficient magnitude) / (1 - reflection coefficient magnitude), where the reflection coefficient magnitude is the ratio of the second power to the first power. Based on this, the target frequency phase combination can be screened by the magnitude of the VSWR.

[0042] In one of the technical solutions, the determining unit is specifically used to: sort the standing wave ratios of each frequency phase combination from smallest to largest to obtain a sorting sequence; and take the frequency phase combinations corresponding to the top N standing wave ratios in the sorting sequence as the target frequency phase combination; where N is a positive integer greater than or equal to 1.

[0043] In this technical solution, the standing wave ratio (SWR) can characterize the heating efficiency. Specifically, the smaller the SWR, the higher the heating efficiency, and vice versa. Using the SWR, multiple frequency phase combinations are sorted to obtain the sorting sequence as described above. Based on the number of frequency phase combinations contained in each target frequency phase combination, i.e., N mentioned above, the N frequency phase combinations corresponding to the top SWRs in the sorting sequence are selected to obtain the target frequency phase combination.

[0044] In this process, the heating efficiency of the food is improved by sorting the target frequency phase combinations to obtain the highest heating efficiency.

[0045] In one of the technical solutions, the control unit is also used to: acquire the duration of the second microwave output by the microwave device; and control the microwave device to stop operating based on the duration being greater than or equal to the first duration.

[0046] In this technical solution, by recording the duration of the second microwave continuous output, i.e. the continuous duration mentioned above, the microwave device is controlled to stop operating when the continuous duration reaches the first duration. In this process, the probability of damage to the microwave device due to prolonged operation can be avoided, and the food located at the heating hot spot can be prevented from being heated for a long time and thus becoming burnt.

[0047] In addition, the first duration can be used as the end condition for a single heating cycle, dividing the heating of the food into multiple heating cycles. That is, after continuously outputting the second microwave for the first duration, the microwave device stops running for one duration, then restarts and outputs the second microwave based on the target frequency phase combination.

[0048] In one of the technical solutions, the control unit is also used to: periodically update the target frequency phase combination; and control the microwave device to output a second microwave based on the updated target frequency phase combination.

[0049] In this technical solution, after the food is heated by microwaves, the temperature of the food itself will rise, and its ability to absorb microwaves will change. By periodically updating the target frequency phase combination, the microwave device can dynamically adjust the output of the second microwave according to the actual situation of the food being cooked, so as to further improve the uniformity of food cooking and reduce the problem of uneven food temperature.

[0050] In one of the technical solutions, the control unit is further configured to: acquire the cumulative duration of the second microwave output by the microwave device; and control the microwave device to stop operating based on the cumulative duration being greater than or equal to the second duration; wherein the second duration is greater than or equal to the first duration.

[0051] In this technical solution, the second time limit can be understood as the total cooking time required for the food. It can be set by the user. By controlling the microwave device to stop operating when the cumulative cooking time exceeds the second time limit, the cooking of the food can be automatically completed.

[0052] In one of the technical solutions, the control unit is also used to: acquire information about the type of food being cooked; and determine the power of the second microwave based on the type information.

[0053] In this technical solution, by acquiring information about the type of food being cooked, the power of the second microwave can be guided by this information, thereby improving the matching degree between the food being cooked and the power of the second microwave. This reduces the chance of the food being burned due to excessive cooking power, and also reduces the occurrence of situations where the food cannot achieve the desired cooking effect due to insufficient cooking power.

[0054] According to a third aspect of the present invention, the present invention provides a control device for a cooking apparatus, comprising: a controller and a memory, wherein the memory stores a program or instructions, and the controller, when executing the program or instructions in the memory, implements the steps of any of the control methods described above.

[0055] According to a fourth aspect of the present invention, a readable storage medium is provided on which a program or instructions are stored, which, when executed by a processor, implement the steps of any of the control methods described above.

[0056] According to a fifth aspect of the present invention, a cooking apparatus is provided, comprising: a control device as described in any of the above-described cooking apparatuses; and / or a readable storage medium as described above.

[0057] The above technical solution also includes: a detection device for detecting the third microwave reflected inside the cooking cavity.

[0058] In the above technical solution, there are multiple microwave devices, and the cooking cavity has multiple feed inlets, with each feed inlet corresponding to one of the multiple microwave devices.

[0068] To better understand the above aspects, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0069] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0070] Example 1

[0071] like Figure 1 As shown, a control method for a cooking device is proposed. The cooking device includes a cooking cavity and a microwave device that feeds microwaves into the cooking cavity. The control method includes:

[0072] Step 102: Control the microwave device to output a first microwave to determine the target frequency phase combination among multiple frequency phase combinations. The frequency and initial phase of the first microwave switch between multiple frequency phase combinations.

[0073] Step 104: Based on the target frequency phase combination, control the microwave device to output a second microwave; wherein the power of the second microwave is greater than the power of the first microwave.

[0074] The embodiments of the present invention propose a control method for a cooking device. By running this control method, the uniformity of heating different ingredients can be improved, thereby ensuring the heating effect.

[0075] Specifically, the microwaves output by the microwave device create heating hotspots at certain locations within the cooking cavity. Food at these hotspots heats up quickly, while food at non-hotspot locations heats up slowly. The location of the heating hotspots also varies depending on the food. Based on this, a first microwave is emitted to serve as a scanning microwave. The frequency and initial phase of this scanning microwave continuously switch between multiple pre-set frequency-phase combinations to find the target frequency-phase combination suitable for heating the current food. This target frequency-phase combination ensures uniform heating, and high-power heating is performed based on this target combination. During this process, the frequency and initial phase of the microwaves output by the microwave device are controlled to improve the uniformity of food heating.

[0076] In the above embodiments, the microwave output by the microwave device is essentially a periodically changing electromagnetic wave, which can be expressed as Asin(2πf+p). Specifically, A is the amplitude, corresponding to the microwave power, f is the microwave frequency, and p is the initial phase of the microwave. Based on this, the frequency-phase combination can be understood as a pair of microwave frequencies and microwave initial phases. Specifically, each frequency-phase combination includes a microwave frequency and an initial phase.

[0077] In the above embodiments, the microwave device may be a magnetron, and it is understood that microwaves are generated based on the magnetron.

[0078] In one embodiment, the frequency in the first microwave continuously varies within a preset frequency range, and the initial phase continuously varies between 0° and 360°, wherein each frequency and each initial phase are combined to obtain a frequency-phase combination.

[0079] Example 2

[0080] In this embodiment, there are at least two target frequency phase combinations, and the frequency output by the microwave device varies within a preset frequency range. The preset frequency range includes at least two frequency intervals, and the at least two target frequency phase combinations correspond to at least two frequency intervals.

[0081] In this embodiment, the preset frequency range can be understood as the frequency at which the microwave device can output microwaves; or the frequency range at which the microwave device is designed to output microwaves. Specifically, the preset frequency range is 2.4 GHz to 2.5 GHz.

[0082] In one embodiment, at least two frequency ranges can be defined as a preset frequency range continuously divided into at least two ranges. It is understood that the maximum value of the previous frequency range is the minimum value of the next frequency range. For example, the first frequency range is 2.4 GHz to 2.45 GHz, and the second frequency range is 2.45 GHz to 2.45 GHz.

[0083] In one embodiment, the at least two frequency ranges can be non-contiguously divided into at least two ranges within a preset frequency range, such as the first frequency range being 2.4 GHz to 2.45 GHz and the second frequency range being 2.47 GHz to 2.45 GHz.

[0084] In the above embodiments, each frequency range corresponds to a set of target frequency phase combinations, and each set of target frequency phase combinations includes at least one frequency phase combination. Based on this, when the second microwave is output based on the target frequency phase combination, the heating hotspots located in the cooking cavity will also switch when different target frequency phase combinations are switched. By combining the frequency phase combinations corresponding to different frequency ranges, a heating matrix composed of heating hotspots can be formed in the cooking cavity. Under the heating of this heating matrix, the food will be heated evenly, thereby improving the heating effect.

[0085] In one embodiment, each target frequency phase combination includes 5 or 10 frequency phase combinations to ensure heating uniformity and heating efficiency.

[0086] In one embodiment, when the microwave device outputs a second microwave, the frequency ranges are sorted, and based on the sorting results, each of the at least two sets of target frequency phase combinations is sorted. At the same time, the frequency phase combinations in each set of target frequency phase combinations are also sorted, and the microwave device is controlled to operate based on the sorting results to achieve the output of the second microwave.

[0087] Furthermore, by dividing the frequency range into at least two frequency ranges, the frequency phase combinations corresponding to different frequency ranges can be distinguished, reducing the problem of excessive proximity of heating hotspots corresponding to different frequency ranges, thereby further ensuring the uniformity of heating.

[0088] Example 3

[0089] In this embodiment, within each frequency range, the microwave device is controlled to output a first microwave to determine a target frequency phase combination among multiple frequency phase combinations. Specifically, this includes: controlling the microwave device to output a first microwave, the power of which is a first power; determining a third microwave reflected within the cooking cavity, the power of which is a second power; and determining the target frequency phase combination based on the first power and the second power.

[0090] In this embodiment, microwave heating uses microwaves to heat food. Therefore, it is desirable for the food to absorb as much microwave as possible, that is, for the temperature to rise as quickly as possible. Based on this, microwaves inside the cooking cavity, i.e., the third microwave, can be collected and the power of the third microwave can be compared with the power of the first microwave to determine how much of the microwave generated by the microwave device has been absorbed by the food. Based on this, a target frequency phase combination can be selected from multiple frequency phase combinations to ensure both heating uniformity and heating efficiency.

[0091] As can be seen from the above, the power of the first microwave is the first power, and the power of the third microwave is the second power. Therefore, multiple frequency phase combinations can be screened based on the difference between the first power and the second power to obtain the target frequency phase combination.

[0092] Specifically, the screening criteria can be determined based on the number of frequency phase combinations contained in each frequency phase combination. The screening criteria are a difference threshold determined based on the number of frequency phase combinations contained in each frequency phase combination. The difference between the first power and the second power is compared with the difference threshold. If the difference between the first power and the second power is greater than the difference threshold, the frequency phase combination corresponding to the second power is taken as the target frequency phase combination.

[0093] Example 4

[0094] In this embodiment, determining the target frequency phase combination based on the first power and the second power specifically includes: determining the standing wave ratio (SWR) of each frequency phase combination based on the first power and the second power; and determining the target frequency phase combination based on the SWR.

[0095] In this embodiment, the concept of standing wave ratio (VSWR) is introduced as a screening condition for multiple frequency phase combinations. Specifically, VSWR = (1 + reflection coefficient magnitude) / (1 - reflection coefficient magnitude), where the reflection coefficient magnitude is the ratio of the second power to the first power. Based on this, the target frequency phase combination can be screened by the magnitude of the VSWR.

[0096] Example 5

[0097] Based on the standing wave ratio (SWR), the target frequency phase combination is determined, specifically by: sorting the SWR of each frequency phase combination from smallest to largest to obtain a sorting sequence; and taking the frequency phase combinations corresponding to the top N SWRs in the sorting sequence as the target frequency phase combination; where N is a positive integer greater than or equal to 1.

[0098] In this embodiment, the standing wave ratio (SWR) can characterize the heating efficiency. Specifically, the smaller the SWR, the higher the heating efficiency, and vice versa. Using the SWR, multiple frequency phase combinations are sorted to obtain the sorting sequence described above. Based on the number of frequency phase combinations contained in each target frequency phase combination, i.e., N mentioned above, the N frequency phase combinations corresponding to the top-ranked SWRs are selected from the sorting sequence to obtain the target frequency phase combination.

[0099] In this process, the heating efficiency of the food is improved by sorting the target frequency phase combinations to obtain the highest heating efficiency.

[0100] Example 6

[0101] In any of the above embodiments, the control method for the cooking device further includes: obtaining the duration of the second microwave output by the microwave device; and controlling the microwave device to stop operating based on the duration being greater than or equal to the first duration.

[0102] In this embodiment, by recording the duration of the second microwave continuous output, i.e. the duration mentioned above, the microwave device is controlled to stop operating when the duration reaches the first duration. In this process, the probability of damage to the microwave device due to prolonged operation can be avoided, and the food located at the heating hot spot can be prevented from being heated for a long time and thus becoming burnt.

[0103] In addition, the first duration can be used as the end condition for a single heating cycle, dividing the heating of the food into multiple heating cycles. That is, after continuously outputting the second microwave for the first duration, the microwave device stops running for one duration, then restarts and outputs the second microwave based on the target frequency phase combination.

[0104] In one embodiment, the first duration can be set according to actual design needs, and its specific value will not be selected here. For example, the first duration can be any duration from 30 seconds to 2 minutes.

[0105] Example 7

[0106] In any of the above embodiments, the control method for the cooking device further includes: periodically updating the target frequency phase combination; and controlling the microwave device to output a second microwave based on the updated target frequency phase combination.

[0107] In this embodiment, after the food is heated by microwaves, the temperature of the food itself will rise, and its ability to absorb microwaves will change. By periodically updating the target frequency phase combination, the microwave device can dynamically adjust the output of the second microwave according to the actual situation of the food being cooked, so as to further improve the uniformity of food cooking and reduce the problem of uneven food temperature.

[0108] In the above embodiments, the target frequency phase combination is updated every first time interval. It can be understood that after the microwave device continuously outputs the second microwave for the first time, the target frequency phase combination is updated, and based on the updated target frequency phase combination, the second microwave continues to be output to achieve continuous heating of the food, thereby shortening the heating time required for the food.

[0109] Example 8

[0110] In any of the above embodiments, the control method for the cooking device further includes: acquiring the cumulative duration of the second microwave output by the microwave device; controlling the microwave device to stop operating based on the cumulative duration being greater than or equal to the second duration; wherein the second duration is greater than or equal to the first duration.

[0111] In this embodiment, the second duration is set, which can be understood as the total cooking time required for the ingredients. It can be set by the user. By controlling the microwave device to stop operating when the cumulative time exceeds the second duration, the cooking of the ingredients can be automatically ended.

[0112] Example 9

[0113] In any of the above embodiments, the control method for the cooking device further includes: acquiring information about the type of food being cooked; and determining the power of the second microwave based on the information about the type.

[0114] In this embodiment, by acquiring information about the type of food being cooked, the power of the second microwave can be guided by this information, thereby improving the matching degree between the food being cooked and the power of the second microwave. This reduces the probability of the food being burned due to excessive cooking power, and also reduces the occurrence of situations where the food cannot achieve the desired cooking effect due to insufficient cooking power.

[0115] In the above embodiments, a correspondence between the type of food being cooked and the power of the second microwave can be pre-built to facilitate finding the power of the second microwave.

[0116] In one embodiment, the correspondence between the type of food being cooked and the power of the second microwave can be learned using the user's historical behavior data, such as storing the type of food being cooked and the cooking power set by the user each time cooking, and using the recorded information as the correspondence discussed above.

[0117] Example 10

[0118] like Figure 2As shown, the present invention provides a control device 200 for a cooking device. The cooking device includes a cooking cavity and a microwave device that feeds microwaves into the cooking cavity. The control device includes: a determining unit 202, used to control the microwave device to output a first microwave to determine a target frequency phase combination among multiple frequency phase combinations, wherein the frequency and initial phase of the first microwave switch among multiple frequency phase combinations; and a control unit 204, used to control the microwave device to output a second microwave based on the target frequency phase combination, wherein the power of the second microwave is greater than the power of the first microwave.

[0119] The embodiments of the present invention provide a control device 200 for a cooking apparatus, which can improve the uniformity of heating different ingredients, thereby ensuring the heating effect.

[0120] Specifically, the microwaves output by the microwave device create heating hotspots at certain locations within the cooking cavity. Food at these hotspots heats up quickly, while food at non-hotspot locations heats up slowly. The location of the heating hotspots also varies depending on the food. Based on this, a first microwave is emitted to serve as a scanning microwave. The frequency and initial phase of this scanning microwave continuously switch between multiple pre-set frequency-phase combinations to find the target frequency-phase combination suitable for heating the current food. This target frequency-phase combination ensures uniform heating, and high-power heating is performed based on this target combination. During this process, the frequency and initial phase of the microwaves output by the microwave device are controlled to improve the uniformity of food heating.

[0121] In the above embodiments, the microwave output by the microwave device is essentially a periodically changing electromagnetic wave, which can be expressed as Asin(2πf+p). Specifically, A is the amplitude, corresponding to the microwave power, f is the microwave frequency, and p is the initial phase of the microwave. Based on this, the frequency-phase combination can be understood as a pair of microwave frequencies and microwave initial phases. Specifically, each frequency-phase combination includes a microwave frequency and an initial phase.

[0122] In the above embodiments, the microwave device may be a magnetron, and it is understood that microwaves are generated based on the magnetron.

[0123] In the above embodiments, there are at least two sets of target frequency phase combinations, and the frequency output by the microwave device varies within a preset frequency range. The preset frequency range includes at least two frequency intervals, and the at least two sets of target frequency phase combinations correspond to at least two frequency intervals.

[0124] In this embodiment, the preset frequency range can be understood as the frequency at which the microwave device can output microwaves; or the frequency range at which the microwave device is designed to output microwaves. Specifically, the preset frequency range is 2.4 GHz to 2.5 GHz.

[0125] In one embodiment, at least two frequency ranges can be defined as a preset frequency range continuously divided into at least two ranges. It is understood that the maximum value of the previous frequency range is the minimum value of the next frequency range. For example, the first frequency range is 2.4 GHz to 2.45 GHz, and the second frequency range is 2.45 GHz to 2.45 GHz.

[0126] In one embodiment, the at least two frequency ranges can be non-contiguously divided into at least two ranges within a preset frequency range, such as the first frequency range being 2.4 GHz to 2.45 GHz and the second frequency range being 2.47 GHz to 2.45 GHz.

[0127] In the above embodiments, each frequency range corresponds to a set of target frequency phase combinations, and each set of target frequency phase combinations includes at least one frequency phase combination. Based on this, when the second microwave is output based on the target frequency phase combination, the heating hotspots located in the cooking cavity will also switch when different target frequency phase combinations are switched. By combining the frequency phase combinations corresponding to different frequency ranges, a heating matrix composed of heating hotspots can be formed in the cooking cavity. Under the heating of this heating matrix, the food will be heated evenly, thereby improving the heating effect.

[0128] In one embodiment, each target frequency phase combination includes 5 or 10 frequency phase combinations to ensure heating uniformity and heating efficiency.

[0129] In one embodiment, when the microwave device outputs a second microwave, the frequency ranges are sorted, and based on the sorting results, each of the at least two sets of target frequency phase combinations is sorted. At the same time, the frequency phase combinations in each set of target frequency phase combinations are also sorted, and the microwave device is controlled to operate based on the sorting results to achieve the output of the second microwave.

[0130] Furthermore, by dividing the frequency range into at least two frequency ranges, the frequency phase combinations corresponding to different frequency ranges can be distinguished, reducing the problem of excessive proximity of heating hotspots corresponding to different frequency ranges, thereby further ensuring the uniformity of heating.

[0131] In any of the above embodiments, within each frequency range, the determining unit 202 is specifically used for: controlling the microwave device to output a first microwave, the power of the first microwave being a first power; determining a third microwave reflected within the cooking cavity, the power of the third microwave being a second power; and determining a target frequency phase combination based on the first power and the second power.

[0132] In this embodiment, microwave heating uses microwaves to heat food. Therefore, it is desirable for the food to absorb as much microwave as possible, that is, for the temperature to rise as quickly as possible. Based on this, microwaves inside the cooking cavity, i.e., the third microwave, can be collected and the power of the third microwave can be compared with the power of the first microwave to determine how much of the microwave generated by the microwave device has been absorbed by the food. Based on this, a target frequency phase combination can be selected from multiple frequency phase combinations to ensure both heating uniformity and heating efficiency.

[0133] As can be seen from the above, the power of the first microwave is the first power, and the power of the third microwave is the second power. Therefore, multiple frequency phase combinations can be screened based on the difference between the first power and the second power to obtain the target frequency phase combination.

[0134] Specifically, the screening criteria can be determined based on the number of frequency phase combinations contained in each frequency phase combination. The screening criteria are a difference threshold determined based on the number of frequency phase combinations contained in each frequency phase combination. The difference between the first power and the second power is compared with the difference threshold. If the difference between the first power and the second power is greater than the difference threshold, the frequency phase combination corresponding to the second power is taken as the target frequency phase combination.

[0135] In one embodiment, the determining unit 202 is specifically configured to: determine the standing wave ratio (SWR) of each frequency phase combination based on the first power and the second power; and determine the target frequency phase combination based on the SWR.

[0136] In this embodiment, the concept of standing wave ratio (VSWR) is introduced as a screening condition for multiple frequency phase combinations. Specifically, VSWR = (1 + reflection coefficient magnitude) / (1 - reflection coefficient magnitude), where the reflection coefficient magnitude is the ratio of the second power to the first power. Based on this, the target frequency phase combination can be screened by the magnitude of the VSWR.

[0137] In one embodiment, the determining unit 202 is specifically used to: sort the standing wave ratios of each frequency phase combination from smallest to largest to obtain a sorting sequence; and take the frequency phase combinations corresponding to the top N standing wave ratios in the sorting sequence as the target frequency phase combinations; where N is a positive integer greater than or equal to 1.

[0138] In this embodiment, the standing wave ratio (SWR) can characterize the heating efficiency. Specifically, the smaller the SWR, the higher the heating efficiency, and vice versa. Using the SWR, multiple frequency phase combinations are sorted to obtain the sorting sequence described above. Based on the number of frequency phase combinations contained in each target frequency phase combination, i.e., N mentioned above, the N frequency phase combinations corresponding to the top-ranked SWRs are selected from the sorting sequence to obtain the target frequency phase combination.

[0139] In this process, the heating efficiency of the food is improved by sorting the target frequency phase combinations to obtain the highest heating efficiency.

[0140] In one embodiment, the control unit 204 is further configured to: acquire the duration of the second microwave output by the microwave device; and control the microwave device to stop operating based on the duration being greater than or equal to the first duration.

[0141] In this embodiment, by recording the duration of the second microwave continuous output, i.e. the duration mentioned above, the microwave device is controlled to stop operating when the duration reaches the first duration. In this process, the probability of damage to the microwave device due to prolonged operation can be avoided, and the food located at the heating hot spot can be prevented from being heated for a long time and thus becoming burnt.

[0142] In addition, the first duration can be used as the end condition for a single heating cycle, dividing the heating of the food into multiple heating cycles. That is, after continuously outputting the second microwave for the first duration, the microwave device stops running for one duration, then restarts and outputs the second microwave based on the target frequency phase combination.

[0143] In one embodiment, the first duration can be set according to actual design needs, and its specific value will not be selected here. For example, the first duration can be any duration from 30 seconds to 2 minutes.

[0144] In one embodiment, the control unit 204 is further configured to: periodically update the target frequency phase combination; and control the microwave device to output a second microwave based on the updated target frequency phase combination.

[0145] In this embodiment, after the food is heated by microwaves, the temperature of the food itself will rise, and its ability to absorb microwaves will change. By periodically updating the target frequency phase combination, the microwave device can dynamically adjust the output of the second microwave according to the actual situation of the food being cooked, so as to further improve the uniformity of food cooking and reduce the problem of uneven food temperature.

[0146] In the above embodiments, the target frequency phase combination is updated every first time interval. It can be understood that after the microwave device continuously outputs the second microwave for the first time, the target frequency phase combination is updated, and based on the updated target frequency phase combination, the second microwave continues to be output to achieve continuous heating of the food, thereby shortening the heating time required for the food.

[0147] In one embodiment, the control unit 204 is further configured to: acquire the cumulative duration of the second microwave output by the microwave device; and control the microwave device to stop operating based on the cumulative duration being greater than or equal to the second duration; wherein the second duration is greater than or equal to the first duration.

[0148] In this embodiment, the second duration is set, which can be understood as the total cooking time required for the ingredients. It can be set by the user. By controlling the microwave device to stop operating when the cumulative time exceeds the second duration, the cooking of the ingredients can be automatically ended.

[0149] In one embodiment, the control unit 204 is further configured to: acquire information about the type of food being cooked; and determine the power of the second microwave based on the information about the type.

[0150] In this embodiment, by acquiring information about the type of food being cooked, the power of the second microwave can be guided by this information, thereby improving the matching degree between the food being cooked and the power of the second microwave. This reduces the probability of the food being burned due to excessive cooking power, and also reduces the occurrence of situations where the food cannot achieve the desired cooking effect due to insufficient cooking power.

[0156] The present invention provides a readable storage medium on which a program or instructions are stored, which, when executed by a processor, implement the steps of the control method of any of the cooking devices described above.

[0157] In this embodiment, when the program or instructions in the readable storage medium are executed, the steps of the control method for the cooking device described above can be implemented. Therefore, it has all the beneficial technical effects of the control method for the cooking device described above, which will not be repeated here.

[0158] Example 13

[0159] The present invention provides a cooking apparatus, comprising: a control device as described in any of the above cooking apparatuses; and / or a readable storage medium as described in the above.

[0160] In the above embodiments, a detection device is also included for detecting a third microwave reflected within the cooking cavity.

[0161] In one embodiment, such as Figure 4 As shown, the cooking equipment is mainly divided into four parts, namely, the control center 402, the microwave source module 404, the heating chamber 406, and the detection module 408. The microwave source module 404 is the microwave device mentioned above, the heating chamber 406 is the cooking cavity mentioned above, and the detection module 408 is the cooking device mentioned above.

[0162] Specifically, the control center 402 is connected to the microwave source module 404 and the detection module 408; the control center 402 controls the microwave source to output different microwave frequencies and phases; the control center 402 receives the detection information sent by the detection module 408 (wherein, the detection information includes the power of the third microwave, that is, the second power).

[0163] Microwave source module 404: Microwave source module 404 is connected to control center 402, detection module 408, and heating chamber 406; microwave source module 404 receives control signals from control center 402 and outputs microwave power with a frequency range of 2.4GHz to 2.5GHz and a phase range of 0° to 360°; microwave source module 404 feeds the output microwave power into heating chamber 406; the output microwave power of microwave source module 404 and the reflected power reflected back from heating chamber 406 can be detected by detection module 408.

[0164] The microwave source module 404 has the following characteristics:

[0165] 1. Microwave source module 404 has two microwave units (i.e., at least two microwave source modules).

[0166] 2. The output power of the microwave source module 404 can be continuously adjusted in frequency from 2.4GHz to 2.5GHz, and the phase can be continuously adjusted in 0° to 360°.

[0167] 3. Different microwave units can operate at the same frequency.

[0168] 4. The microwave source module 404 can be continuously adjusted within the maximum output power range.

[0169] Among them, the detection module 408 is connected to the microwave source module 404 and the control center 402; the detection module 408 can detect the output power of the microwave source module 404 and the reflected power reflected from the heating chamber 406 to the microwave source module 404; the detection module 408 feeds back the detected information to the control center 402.

[0170] Among them, heating chamber 406: heating chamber 406 is connected to microwave source module 404; heating chamber 406 is used to place food to be heated; heating chamber 406 receives the output power of microwave source module 404 to heat the food placed in it.

[0171] Additional explanation: Each combination of microwave power at different frequencies and phases creates a corresponding field distribution within the heating chamber 406. If the heating chamber 406 is divided into several regions, the electromagnetic field strength in each region will be inconsistent. When the phase and frequency change, the electromagnetic field strength in each region will also change. Correspondingly, objects placed in areas with stronger field strength will heat up faster, while objects placed in areas with weaker field strength will heat up more slowly (for the same or similar materials).

[0172] In the above embodiments, there are multiple microwave devices, and the cooking cavity has multiple feed inlets, with each feed inlet corresponding to one of the multiple microwave devices.

[0173] like Figure 5 As shown, the control methods for the cooking equipment include:

[0174] Step 502: Power on the device and put in the food.

[0175] Step 504: Use low-power scanning to acquire detection data.

[0176] The low power can be 10W or 20W. By using low power scanning and analysis, the microwave reflection power information of all frequency and phase combinations can be detected by changing the frequency and phase.

[0177] Step 506: Calculate the frequency-phase combination X×N with the minimum standing wave ratio in each interval.

[0178] Specifically, the frequency range of 2.4GHz to 2.5GHz is divided into X frequency intervals (e.g., 2.4GHz to 2.45GHz, 2.45GHz to 2.5GHz). Within each frequency interval, N frequency phase combinations with the smallest standing wave ratio (highest heating efficiency) are found (N can be 5 or 10, etc., which can be set according to the requirements of uniformity and efficiency).

[0179] Step 508: Use the frequency-phase combination calculated in the previous step to perform high-power cooking for the first duration.

[0180] Step 510: Determine whether the cooking time is complete. If the result is yes, end the process; if the result is no, proceed to step 504.

[0181] The cooking time is also the second duration mentioned above.

[0182] In this embodiment, heating with multiple frequency and phase combinations is beneficial for uniform cooking and shortens the development time of automatic menus; heating with multiple frequency and phase combinations ensures both uniform cooking and efficiency; filtering by multiple zones avoids similar intensity distribution in the heating chamber and prevents prolonged heating of the same area.
