[0058] In order to more clearly understand the above aspects, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0059] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0060] According to one embodiment of the present invention, a control method for a cooking device is provided. The cooking device includes a control device and N microwave sources connected to the control device, wherein M microwave sources of the N microwave sources emit microwaves with different frequency bands, and M is a positive integer less than or equal to N and greater than or equal to 2. The control method includes:

[0061] The driving control device sends control information to control the operation of at least one microwave source among the N microwave sources.

[0062] The technical solution of the present application proposes a control method for cooking equipment, which drives a control device to send control information to achieve control of multiple microwave sources. In this process, the control device can control not only a single microwave source, but multiple microwave sources, and can also control the operation of microwave sources that output microwaves in different frequency bands. In this process, the probability of semiconductor microwave heating equipment failing to work when the microwave source is replaced is reduced, ensuring the accurate operation of the microwave source, thereby improving the reliability of the operation of the cooking equipment. Figure 1 As shown, the control method also includes:

[0063] Step 102, driving the control device to send query information to N microwave sources;

[0064] Step 104, receiving feedback information from N microwave sources;

[0065] Step 106: Determine control information according to the feedback information.

[0066] In this embodiment, by running the control method, the microwave source can be actively identified, and control information matching the microwave source can be issued, thereby ensuring the accurate operation of the microwave source, thereby improving the reliability of the operation of the cooking device.

[0067] The embodiments of the present application are implemented based on the following principles. Specifically, query information is sent to a microwave source so that the microwave source feeds back feedback information matching the query information after receiving the query information, so as to use the feedback information to determine control information matching the microwave source and execute control of the microwave source. In this process, the control information is determined based on the feedback information fed back by the microwave source, thereby ensuring that the control information and the microwave source are matched, reducing the probability of the microwave source failing to work due to mismatch between the two, and thereby improving the reliability of the operation of the cooking device.

[0068] In addition, the above-mentioned embodiments of the present application can automatically adjust the control information after the microwave source is damaged and replaced, without the need for manual adjustment by maintenance personnel. Therefore, the workload of maintaining the cooking equipment is reduced and the maintenance efficiency is improved. At the same time, the probability of maintenance errors is reduced and the reliability of the operation of the cooking equipment is improved.

[0069] In one embodiment, the query information may be an instruction containing actual content or an instruction not containing actual content. Specifically, for example, an instruction containing actual content may be understood as the query information containing an instruction requesting the microwave frequency band supported by the microwave source, so that the microwave source provides feedback information after receiving the instruction requesting the microwave frequency band supported by the microwave source; an instruction not containing actual content may be understood as empty information, and at this time, the microwave source can respond to the empty information to provide feedback information.

[0070] In one embodiment, the query information may exist alone or be transmitted together with other information that needs to be sent to the microwave source. By limiting the query information to be transmitted together with other information that needs to be sent to the microwave source, the number of interactions with the microwave source can be reduced, thereby improving the interaction efficiency.

[0071] In one embodiment, the feedback information may exist alone or be transmitted together with the information sent by the microwave source. By limiting the feedback information to be transmitted together with other information that needs to be sent by the microwave source, the number of interactions with the microwave source can be reduced, thereby improving the interaction efficiency.

[0072] In the above embodiment, the feedback information includes: the frequency range of the microwaves output by the microwave source when it is in operation.

[0073] In this embodiment, the feedback information is limited to include the frequency range of microwaves that the microwave source can output, so that in the process of controlling the microwave source, the microwave source is controlled to emit microwaves within the frequency range, thereby reducing the probability of the microwave source being unable to work normally due to the mismatch between the control information and the microwave source, and the microwave source being controlled to emit microwaves in an unsupported frequency band.

[0074] In any of the above embodiments, the frequency interval includes one or more of the following: between 433.05 MHz and 434.79 MHz, between 902 MHz and 928 MHz, and between 2400 MHz and 2500 MHz.

[0075] In any of the above embodiments, the control information includes the frequency of the microwaves output by the microwave source; wherein the frequency of the microwaves output by the microwave source is within a frequency range.

[0076] In this embodiment, the content included in the control information is specifically limited. Through the above-mentioned limitation, it is ensured that the control information can control the microwave source to emit microwaves within the supported output frequency band, thereby improving the probability of normal operation of the microwave source.

[0077] For example, a microwave source can output microwaves between 902 MHz and 928 MHz. At this time, the control information needs to control the microwave source to emit microwaves of 915 MHz. Since 915 MHz is between 902 MHz and 928 MHz, the microwave source can emit microwaves in this frequency band and can operate normally. If the control information needs to control the microwave source to emit microwaves of 2450 MHz, and 2450 MHz is not between 902 MHz and 928 MHz, the microwave source cannot emit microwaves in this frequency band. At this time, the microwave source cannot operate normally. The above-mentioned limitation is used to ensure that the control information can control the microwave source to emit microwaves within the supported output frequency band, thereby increasing the probability of the microwave source operating normally.

[0078] In any of the above embodiments, the control information further includes: microwave power of the output microwave of the microwave source.

[0079] In this embodiment, the control information is limited to also include microwave power so as to control the microwave source to output energy within the microwave frequency band it supports, thereby achieving cooking of ingredients. By limiting the microwave power, different cooking functions of the cooking equipment can be matched to ensure cooking diversity.

[0080] Specifically, when the frequency range is between 433.05MHz and 434.79MHz (the center frequency is 433.92MHz), the maximum power output is 500 watts; when the frequency range is between 902MHz and 928MHz (the center frequency is 915MHz), the maximum power output is 500 watts; when the frequency range is between 2400MHz and 2500MHz MHz (the center frequency is 2450MHz), the maximum power output is 250 watts to meet the power requirements of different cooking functions.

[0081] In one embodiment, if Figure 2 As shown, the control method of the cooking device includes:

[0082] Step 202, after the device is powered on, the control device queries the microwave source information;

[0083] Step 204, the microwave source reports the information of the module;

[0084] Step 206 , the control device sends control information such as microwave frequency and microwave function supported by the microwave source according to the module information reported by the microwave source to control the operation of the microwave source.

[0085] Among them, the control device can be understood as a device in the cooking device for controlling the microwave source, querying the microwave source information can be understood as sending query information, and the information reported by the microwave source to this module can be understood as sending feedback information to the control device.

[0086] In one embodiment, the present invention provides a control method for a cooking device, the cooking device comprising a microwave source, such as Figure 3 As shown, the control method includes:

[0087] Step 302, receiving control information of a microwave source, wherein the control information includes control parameters without units;

[0088] Step 304, obtaining frequency parameter information of the microwave source;

[0089] Step 306, determining the target frequency of the microwaves output by the microwave source according to the frequency parameter information and the control parameter;

[0090] Step 308: Control the microwave source to output microwaves of target frequency.

[0091] The embodiment of the present application proposes a control method for a cooking device. By running the control method, the problem of mismatch between control information and a microwave source is solved, and accurate control of an existing microwave source can be achieved, thereby improving the reliability of the operation of the cooking device.

[0092] The embodiments of the present application are implemented based on the following principles. Specifically, by limiting the control information to include control parameters without units, the influence of the units of the control parameters on the control of the microwave source is eliminated, so that the control information can be applied to different microwave sources. By obtaining frequency parameter information, the target frequency of the microwave output by the microwave source is restored according to the frequency parameter information and the control parameters, so that the microwave source can output microwaves according to the target frequency. In the above process, the universal control of the existing microwave source can be realized, and the existing control software can only control the operation of the microwave source in this frequency band. At the same time, the above embodiments of the present application can automatically adjust the control information after the microwave source is damaged and replaced, without the need for manual adjustment by the maintenance personnel. Therefore, the workload of maintaining the cooking equipment is reduced, the maintenance efficiency is improved, and at the same time, the probability of maintenance errors is reduced, and the reliability of the operation of the cooking equipment is improved.

[0093] In one embodiment, the control parameter may be a numerical value, such as a positive integer 1, 2, 3, etc.

[0094] In the above embodiment, the frequency parameter information includes a reference frequency and a frequency adjustment step. Determining the target frequency of the microwaves output by the microwave source according to the frequency parameter information and the control parameters includes: determining a frequency offset according to the frequency adjustment step and the control parameters; and taking the sum of the reference frequency and the frequency offset as the target frequency.

[0095] In this embodiment, a detailed calculation scheme of the target frequency is specifically provided. In this calculation scheme, the frequency offset is determined by using the control parameter and the frequency adjustment step, and the determined frequency offset is added to the reference frequency to obtain the target frequency.

[0096] In the above embodiment, since the target frequency determination process involves the reference frequency of the microwave source, the determined target frequency can be adapted to the microwave source, thereby ensuring that the control information can control the microwave source and reducing the probability of the microwave source failing to work due to the mismatch between the two. Based on this, the reliability of the cooking device operation is improved.

[0097] In one of the embodiments, the frequency adjustment step size can be understood as the frequency change value during a single adjustment, and the corresponding control parameter can be understood as the number of frequency adjustments.

[0098] In any of the above embodiments, the product of the frequency adjustment step length and the control parameter is used as the frequency offset.

[0099] In this embodiment, a detailed determination scheme for the frequency offset is given, in which the product of the control parameter and the frequency adjustment step is calculated to determine the accumulated frequency change value of the frequency adjustment of the control parameter times, that is, the frequency offset mentioned above, and the frequency offset is superimposed on the reference frequency to obtain the target frequency.

[0100] In any of the above embodiments, the method further includes: determining a frequency range in which microwaves that can be output by the microwave source are located; and determining a reference frequency and a frequency adjustment step according to the frequency range.

[0101] In this embodiment, the method for determining the frequency adjustment step and the reference frequency is specifically defined, wherein the frequency adjustment step and the reference frequency are determined according to the frequency range in which the microwaves that the microwave source can output are located, so as to ensure that the target frequency determined by superimposing the frequency offset determined according to the frequency adjustment step and the control parameters and the reference frequency is still within the frequency range, thereby reducing the probability of the target frequency exceeding the frequency range and improving the accuracy of microwave source control.

[0102] In any of the above embodiments, the frequency interval includes one or more of the following: between 433.05 MHz and 434.79 MHz, between 902 MHz and 928 MHz, and between 2400 MHz and 2500 MHz.

[0103] In this embodiment, when the frequency interval is between 433.05 MHz and 434.79 MHz, the reference frequency is 433.05 MHz, and the frequency adjustment step is 0.01 MHz; when the frequency interval is between 902 MHz and 928 MHz, the reference frequency is 902 MHz, and the frequency adjustment step is 1 MHz; when the frequency interval is between 2400 MHz and 2500 MHz, the reference frequency is 2400 MHz, and the frequency adjustment step is 1 MHz.

[0104] Specifically, if the frequency control information sent without a unit is 15:

[0105] The operating frequencies of different microwave sources are:

[0106] 433.05MHz to 434.79MHz, operating frequency = 433.05MHz + 0.01MHz × 15 = 433.20MHz;

[0107] 902MHz~928MHz, operating frequency = 902MHz + 1MHz × 15 = 917MHz;

[0108] 2400MHz~2500MHz, operating frequency=2400MHz+1MHz×15=2415MHz.

[0109] The operating frequency is also the target frequency mentioned above.

[0110] In any of the above embodiments, the number of the microwave source is at least one.

[0111] In this embodiment, the number of microwave sources is limited to at least one, so as to achieve simultaneous control of multiple microwave sources to meet different heating requirements.

[0112] In one embodiment, Figure 4 As shown, the present invention provides a control device 400 for a cooking device, the cooking device comprising a control device and N microwave sources connected to the control device, wherein M of the N microwave sources emit microwaves in different frequency bands, M is a positive integer less than or equal to N and greater than or equal to 2, and the control device comprises: a first control unit 402, used to drive the control device to send control information to control the operation of at least one of the N microwave sources.

[0113] The technical solution of the present application proposes a control device 400 for a cooking device. The cooking device equipped with the control device sends control information to realize the control of multiple microwave sources. During this process, the control device can control not only a single microwave source, but multiple microwave sources. At the same time, it can also control the operation of microwave sources that output microwaves in different frequency bands. During this process, the probability of the semiconductor microwave heating device failing to work once the microwave source is replaced is reduced, thereby ensuring the accurate operation of the microwave source and improving the reliability of the operation of the cooking device.

[0114] In one of the technical solutions, the first control unit 402 is further used to: drive the control device to send query information to N microwave sources; receive feedback information from the N microwave sources; and determine control information according to the feedback information.

[0115] In this embodiment, the cooking device having the control device can actively identify the microwave source and send out control information matching the microwave source, thereby ensuring the accurate operation of the microwave source, thereby improving the reliability of the operation of the cooking device.

[0116] The embodiments of the present application are implemented based on the following principles. Specifically, query information is sent to a microwave source so that the microwave source feeds back feedback information matching the query information after receiving the query information, so as to use the feedback information to determine control information matching the microwave source and execute control of the microwave source. In this process, the control information is determined based on the feedback information fed back by the microwave source, thereby ensuring that the control information and the microwave source are matched, reducing the probability of the microwave source failing to work due to mismatch between the two, and thereby improving the reliability of the operation of the cooking device.

[0117] In addition, the above-mentioned embodiments of the present application can automatically adjust the control information after the microwave source is damaged and replaced, without the need for manual adjustment by maintenance personnel. Therefore, the workload of maintaining the cooking equipment is reduced and the maintenance efficiency is improved. At the same time, the probability of maintenance errors is reduced and the reliability of the operation of the cooking equipment is improved.

[0118] In one embodiment, the query information may be an instruction containing actual content or an instruction not containing actual content. Specifically, for example, an instruction containing actual content may be understood as the query information containing an instruction requesting the microwave frequency band supported by the microwave source, so that the microwave source provides feedback information after receiving the instruction requesting the microwave frequency band supported by the microwave source; an instruction not containing actual content may be understood as empty information, and at this time, the microwave source can respond to the empty information to provide feedback information.

[0119] In one embodiment, the query information may exist alone or be transmitted together with other information that needs to be sent to the microwave source. By limiting the query information to be transmitted together with other information that needs to be sent to the microwave source, the number of interactions with the microwave source can be reduced, thereby improving the interaction efficiency.

[0120] In one embodiment, the feedback information may exist alone or be transmitted together with the information sent by the microwave source. By limiting the feedback information to be transmitted together with other information that needs to be sent by the microwave source, the number of interactions with the microwave source can be reduced, thereby improving the interaction efficiency.

[0121] In the above embodiment, the feedback information includes: the frequency range in which the microwaves that the microwave source can output are located.

[0122] In this embodiment, the feedback information is limited to include the frequency range of microwaves that the microwave source can output, so that in the process of controlling the microwave source, the microwave source is controlled to emit microwaves within the frequency range, thereby reducing the probability of the microwave source being unable to work normally due to the mismatch between the control information and the microwave source, and the microwave source being controlled to emit microwaves in an unsupported frequency band.

[0123] In any of the above embodiments, the frequency interval includes one or more of the following: between 433.05 MHz and 434.79 MHz, between 902 MHz and 928 MHz, and between 2400 MHz and 2500 MHz.

[0124] In any of the above embodiments, the control information includes the frequency of the microwaves output by the microwave source; wherein the frequency of the microwaves output by the microwave source is within a frequency range.

[0125] In this embodiment, the content included in the control information is specifically limited. Through the above-mentioned limitation, it is ensured that the control information can control the microwave source to emit microwaves within the supported output frequency band, thereby improving the probability of normal operation of the microwave source.

[0126] For example, a microwave source can output microwaves between 902 MHz and 928 MHz. At this time, the control information needs to control the microwave source to emit microwaves of 915 MHz. Since 915 MHz is between 902 MHz and 928 MHz, the microwave source can emit microwaves in this frequency band and can operate normally. If the control information needs to control the microwave source to emit microwaves of 2450 MHz, and 2450 MHz is not between 902 MHz and 928 MHz, the microwave source cannot emit microwaves in this frequency band. At this time, the microwave source cannot operate normally. The above-mentioned limitation is used to ensure that the control information can control the microwave source to emit microwaves within the supported output frequency band, thereby increasing the probability of the microwave source operating normally.

[0127] In any of the above embodiments, the control information further includes: microwave power of the output microwave of the microwave source.

[0128] In this embodiment, the control information is limited to also include microwave power so as to control the microwave source to output energy within the microwave frequency band it supports, thereby achieving cooking of ingredients. By limiting the microwave power, different cooking functions of the cooking equipment can be matched to ensure cooking diversity.

[0129] Specifically, when the frequency range is between 433.05MHz and 434.79MHz (the center frequency is 433.92MHz), the maximum power output is 500 watts; when the frequency range is between 902MHz and 928MHz (the center frequency is 915MHz), the maximum power output is 500 watts; when the frequency range is between 2400MHz and 2500MHz MHz (the center frequency is 2450MHz), the maximum power output is 250 watts to meet the power requirements of different cooking functions.

[0130] In one embodiment, Figure 5 As shown, the present invention provides a control device 500 for a cooking device, the cooking device includes a microwave source, and the control device includes: a receiving unit 502, used to receive control information of the microwave source, wherein the control information includes control parameters without units; an acquisition unit, used to acquire frequency parameter information of the microwave source; a determination unit 504, used to determine a target frequency of microwaves output by the microwave source according to the frequency parameter information and the control parameters; and a second control unit 506, used to control the microwave source to output microwaves of the target frequency.

[0131] The embodiments of the present application provide a control device for a cooking device. The cooking device with the control device gets rid of the problem of mismatch between control information and a microwave source, and can achieve accurate control of an existing microwave source, thereby improving the reliability of the operation of the cooking device.

[0132] The embodiments of the present application are implemented based on the following principles. Specifically, by limiting the control information to include control parameters without units, the influence of the units of the control parameters on the control of the microwave source is eliminated, so that the control information can be applied to different microwave sources. By obtaining frequency parameter information, the target frequency of the microwave output by the microwave source is restored according to the frequency parameter information and the control parameters, so that the microwave source can output microwaves according to the target frequency. In the above process, the universal control of the existing microwave source can be realized, and the existing control software can only control the operation of the microwave source in this frequency band. At the same time, the above embodiments of the present application can automatically adjust the control information after the microwave source is damaged and replaced, without the need for manual adjustment by the maintenance personnel. Therefore, the workload of maintaining the cooking equipment is reduced, the maintenance efficiency is improved, and at the same time, the probability of maintenance errors is reduced, and the reliability of the operation of the cooking equipment is improved.

[0133] In one embodiment, the control parameter may be a numerical value, such as a positive integer 1, 2, 3, etc.

[0134] In the above embodiment, the frequency parameter information includes a reference frequency and a frequency adjustment step. The determination unit 504 is specifically configured to: determine a frequency offset according to the frequency adjustment step and the control parameter; and use the sum of the reference frequency and the frequency offset as the target frequency.

[0135] In this embodiment, a detailed calculation scheme of the target frequency is specifically provided. In this calculation scheme, the frequency offset is determined by using the control parameter and the frequency adjustment step, and the determined frequency offset is added to the reference frequency to obtain the target frequency.

[0136] In the above embodiment, since the target frequency determination process involves the reference frequency of the microwave source, the determined target frequency can be adapted to the microwave source, thereby ensuring that the control information can control the microwave source and reducing the probability of the microwave source failing to work due to the mismatch between the two. Based on this, the reliability of the cooking device operation is improved.

[0137] In one of the embodiments, the frequency adjustment step size can be understood as the frequency change value during a single adjustment, and the corresponding control parameter can be understood as the number of frequency adjustments.

[0138] In any of the above embodiments, the product of the frequency adjustment step length and the control parameter is used as the frequency offset.

[0139] In this embodiment, a detailed determination scheme for the frequency offset is given, in which the product of the control parameter and the frequency adjustment step is calculated to determine the accumulated frequency change value of the frequency adjustment of the control parameter times, that is, the frequency offset mentioned above, and the frequency offset is superimposed on the reference frequency to obtain the target frequency.

[0140] In any of the above embodiments, the determination unit 504 is further configured to: determine a frequency interval in which microwaves that can be output by the microwave source are located; and determine a reference frequency and a frequency adjustment step according to the frequency interval.

[0142] In any of the above embodiments, the frequency interval includes one or more of the following: between 433.05 MHz and 434.79 MHz, between 902 MHz and 928 MHz, and between 2400 MHz and 2500 MHz.

[0143] In this embodiment, when the frequency interval is between 433.05 MHz and 434.79 MHz, the reference frequency is 433.05 MHz, and the frequency adjustment step is 0.01 MHz; when the frequency interval is between 902 MHz and 928 MHz, the reference frequency is 902 MHz, and the frequency adjustment step is 1 MHz; when the frequency interval is between 2400 MHz and 2500 MHz, the reference frequency is 2400 MHz, and the frequency adjustment step is 1 MHz.

[0144] In any of the above embodiments, the number of the microwave source is at least one.

[0145] In this embodiment, the number of microwave sources is limited to at least one, so as to achieve simultaneous control of multiple microwave sources to meet different heating requirements.

[0148] Specifically, microwave source one 704: the microwave source one 704 is connected to the control device 702; the microwave source one 704 receives the control signal of the control device 702, and outputs microwave power in the frequency range of 2400MHz to 2500MHz; microwave source two 706: the microwave source two 706 is connected to the control device 702; the microwave source two 706 receives the control signal of the control device 702, and outputs microwave power in the frequency range of 902MHz to 928MHz; microwave source three 708: the microwave source three 708 is connected to the control device 702; the microwave source three 708 receives the control signal of the control device 702, and outputs microwave power in the frequency range of 433.05MHz to 434.79MHz.
