[0001] The present invention belongs to the technical field of cooking devices, and in particular, relates to a cooking device, a control method thereof, a control device, and a readable storage medium. Background Art

[0002] In the prior art, electromagnetic heating devices generate radiation during operation. In related technologies, filters are added to absorb the radiation energy generated by the electromagnetic heating devices, resulting in increased costs. Summary of the Invention

[0003] The present invention aims to solve one of the technical problems existing in the prior art or related technologies.

[0004] To this end, a first aspect of the present invention provides a control method for a cooking device.

[0005] A second aspect of the present invention provides a control device for a cooking device.

[0006] A third aspect of the present invention provides a control device for a cooking device.

[0007] A fourth aspect of the present invention provides a readable storage medium.

[0008] A fifth aspect of the present invention provides a cooking device.

[0009] In view of this, according to a first aspect of the present invention, a control method for a cooking device is provided. The cooking device includes an electromagnetic heating device, and the control method includes: obtaining a first duration, where the first duration is the duration required for the operating voltage value of the electromagnetic heating device to rise to a set voltage value during the process of the electromagnetic heating device operating at a first pulse width; determining a second duration according to a set period and the first duration, where the second duration is the duration for the electromagnetic heating device to operate at a second pulse width within the set period; controlling the operation of the electromagnetic heating device according to the first pulse width, the second pulse width, the first duration, the second duration, and the set period; where the second pulse width is less than the first pulse width.

[0010] The control method for a cooking device provided by the present invention is used for a cooking device provided with an electromagnetic heating device. The cooking device includes a main body, a cooking cavity, and an electromagnetic heating device. The cooking cavity is arranged in the main body of the cooking device, and the electromagnetic heating device can perform electromagnetic heating on the cooking cavity after being powered on.

[0011] At the beginning stage of cooking, the electromagnetic heating device operates according to the first pulse width, starts timing, and continuously obtains the voltage value during the operation of the electromagnetic heating device. When it is detected that the operating voltage value reaches the set voltage value, the timing is completed to obtain the first duration. It should be noted that when the operating voltage value reaches the set voltage value, it is determined that radiation is generated during the operation of the electromagnetic heating device. Therefore, the first duration is the maximum duration for the electromagnetic heating device to operate according to the first pulse width. Obtain the set period for the electromagnetic heating device to be powered on. Within the set period, the electromagnetic heating device can continuously operate according to the first pulse width until it reaches the first duration. That is, the second duration for the electromagnetic heating device to operate according to the second pulse width can be calculated based on the set period. Since the second pulse width is smaller than the first pulse width, it can ensure that the operating voltage value during the operation of the electromagnetic heating device according to the second pulse width is less than the set voltage value, that is, the electromagnetic heating device will not generate radiation.

[0012] The present invention controls the operation of the electromagnetic heating device, collects the longest operating duration for the electromagnetic heating device to operate according to the first pulse width, that is, the first duration. And calculates the second duration for the operation of the electromagnetic heating device based on the set period and the first duration. By controlling the electromagnetic heating device to first continuously operate at the larger first pulse width for the first duration, then continuously operate at the smaller second pulse width for the second duration, and then continue to continuously operate at the larger first pulse width for the second duration within a set period. It realizes that the electromagnetic heating device does not generate radiation during operation within the set period, while ensuring that the electromagnetic heating device operates at a larger power, that is, ensuring the heating efficiency of the electromagnetic heating device for the cooking cavity. And it is possible to avoid the electromagnetic heating device from generating radiation without setting a filter in the electromagnetic heating device, reducing the production cost of the cooking device.

[0013] It should be noted that since the power supply of the electromagnetic heating device is selected as the mains power, that is, sinusoidal alternating current. The electromagnetic heating device starts to operate after passing through the zero crossing, that is, the electromagnetic heating device continuously operates according to the first pulse width until it reaches the first duration. At this time, the peak of the alternating current voltage has not been reached. Control the operation device of the electromagnetic heating device to continuously operate according to the second pulse width for the second duration. Since the second duration is the duration calculated based on the cycle duration of the alternating current, the electromagnetic heating device is at the peak of the alternating current when operating according to the second pulse width for the second duration. After reaching the second duration, the electromagnetic heating device continues to continuously operate according to the first pulse width for the first duration, that is, the electromagnetic heating device completes the operation of the entire cycle.

[0014] In some embodiments, the value range of the first pulse width is 8 μs to 10 μs, and the value range of the second pulse width is 6 μs to 8 μs.

[0015] In these embodiments, since the alternating current input to the electromagnetic heating device is at the peak during the process of the electromagnetic heating device operating according to the second pulse width, setting the second pulse width to be less than the first pulse width can effectively avoid radiation generated during the operation of the electromagnetic heating device with the second pulse width.

[0016] In addition, according to the control method of the cooking device in the above technical solution provided by the present invention, the following additional technical features may also be included:

[0017] In a possible design, obtaining the first duration includes: based on the current of the electromagnetic heating device being at the zero crossing point, controlling the electromagnetic heating device to operate with the first pulse width; collecting the first voltage value of the electromagnetic heating device; based on the first voltage value reaching the set voltage value, controlling the electromagnetic heating device to stop operating, and obtaining the duration of operation of the electromagnetic heating device to obtain the first duration.

[0018] In this design, the electromagnetic heating device is powered on and operated by inputting alternating current to the electromagnetic heating device. When the alternating current input to the battery heating device reaches the zero crossing point, the electromagnetic heating device is controlled to start operating according to the first pulse width. After the electromagnetic heating device starts operating, the first voltage value during the operation of the electromagnetic heating device is continuously collected. Since the alternating current input to the electromagnetic heating device is sinusoidal alternating current, the operating voltage value of the electromagnetic heating device is in a continuously increasing state. When it is detected that the first voltage value is equal to the set voltage value, the electromagnetic heating device is shut down. During the process of controlling the electromagnetic heating device to operate with the first pulse width, the operating duration of the electromagnetic heating device is continuously timed to determine the first duration, that is, starting from the zero crossing point of the current, controlling the electromagnetic heating device to operate according to the first pulse width. When the operating duration of the electromagnetic heating device does not reach the first duration, the electromagnetic heating device will not generate radiation.

[0019] The present invention controls the electromagnetic heating device to start operating when the alternating current reaches the zero crossing point, so that the set period of the electromagnetic heating device coincides with the period of the alternating current, and the first duration of the electromagnetic heating device operating with the first pulse width is timed, improving the accuracy of the obtained first duration. Thus, it is realized that during the process of controlling the electromagnetic heating device to operate with the first pulse width for the first duration, the electromagnetic heating device will not generate radiation. Since the first pulse width is a relatively high pulse width, the operating power of the electromagnetic heating device is increased on the premise of ensuring that the electromagnetic heating device does not generate radiation.

[0020] It can be understood that when the electromagnetic heating device operates at the set voltage value, the electromagnetic heating device will generate radiation. By controlling the electromagnetic heating device to operate at a voltage less than the set voltage value, it is possible to avoid radiation generated by the electromagnetic heating device during the heating operation.

[0021] In a possible design, to determine a second duration according to a set period and a first duration, it includes: calculating the difference between the duration of the set period and twice the first duration to obtain the second duration.

[0022] In this design, the total duration of the set period is a fixed duration, and the first duration is the operating duration when the electromagnetic heating device operates according to the first pulse width within the set period. Since the power supply of the electromagnetic heating device is selected as the mains power, that is, sinusoidal alternating current. The process of the electromagnetic heating device continuously operating according to the second pulse width is set at the peak of the alternating current voltage. Therefore, by subtracting twice the first duration from the period duration of the set period, the second duration is obtained.

[0023] At the beginning stage of the set period, that is, controlling the electromagnetic heating device to operate according to the first pulse width through the zero-crossing of the current. After the operating duration reaches the first duration, controlling the electromagnetic heating device to operate according to the second pulse width for the second duration, and then controlling the electromagnetic heating device to continuously operate according to the first pulse width until reaching the first duration, so as to complete the adjustment of the pulse width of the electromagnetic heating device within one period.

[0024] The present invention can avoid the generation of radiation during the operation of the electromagnetic heating device due to the increase in the supply voltage by controlling the electromagnetic heating device to operate at a lower second pulse width at the voltage peak. And controlling the electromagnetic heating device to operate at a higher first pulse width during the remaining time of the period. It realizes avoiding the generation of radiation by the electromagnetic heating device while ensuring the heating efficiency of the electromagnetic heating device.

[0025] In a possible design, to control the operation of the electromagnetic heating device according to the first pulse width, the second pulse width, the first duration, the second duration, and the set period, it includes: controlling the electromagnetic heating device to operate cyclically according to the set period; within the set period, controlling the electromagnetic heating device to operate according to the first pulse width, the first duration, the second pulse width, and the second duration.

[0026] In this design, the electromagnetic heating device operates cyclically with the set period, that is, after the electromagnetic heating device completes an operation with this set period, it continues to operate with the set period. During the operation of the set period, the electromagnetic heating device first continuously operates according to the first pulse width until reaching the first duration, then operates according to the second pulse width for the second duration, and then continues to continuously operate according to the first pulse width until reaching the first duration, so as to complete the operation within one set period. After completing the operation within one set period, it starts to operate with the set period again.

[0027] During the first time period at the beginning of the set period and the first time period before the end of the set period, the electromagnetic heating device is controlled to operate with a relatively large first pulse width, which ensures the heating power of the electromagnetic heating device within the set period. During the voltage peak section of the set period, the electromagnetic heating device is controlled to operate with a relatively small first pulse width, avoiding the problem of radiation generated by the electromagnetic heating device under a high voltage. The electromagnetic heating device does not generate radiation within the set period. Therefore, by controlling the electromagnetic heating device to operate in a cycle according to the set period, the stable operation of the electromagnetic heating device is achieved.

[0028] In a possible design, controlling the electromagnetic heating device to operate according to the first pulse width, the first time period, the second pulse width, and the second time period includes: controlling the electromagnetic heating device to operate with the first pulse width; based on the operation time of the electromagnetic heating device reaching the first time period, controlling the electromagnetic heating device to operate with the second pulse width; based on the operation time of the electromagnetic heating device operating with the second pulse width reaching the second time period, controlling the electromagnetic heating device to continuously operate with the first pulse width until reaching the first time period.

[0029] In this design, at the current zero-crossing point, the electromagnetic heating device is controlled to start operating with the first pulse width, continuously detecting the operation time of the electromagnetic heating device. After detecting that the operation time reaches the first time period, if it is determined that radiation will be generated if continuing to operate with the first pulse width, then it continues to operate with the second pulse width. After detecting that the operation time of the electromagnetic heating device operating with the second pulse width reaches the second time period, if it is determined that no radiation will be generated if continuing to operate with the first pulse width, then it continuously operates with the first pulse width until reaching the first time period, thereby completing the control of the electromagnetic heating device within the entire set period.

[0030] It can be understood that since the first pulse width is greater than the second pulse width, the heating efficiency of the electromagnetic heating device when operating with the first pulse width is higher than that when operating with the second pulse width. Therefore, in this application, by controlling the electromagnetic heating device to operate with the relatively high first pulse width at both the beginning stage and the end stage of the set period, the heating efficiency of the electromagnetic heating device is ensured.

[0031] It should be noted that at the current zero-crossing point, the electromagnetic heating device is controlled to start operating according to the set period, that is, the set period is the power supply period of the alternating current. The operating voltages of the electromagnetic heating device are the same during the first time period at the beginning stage and the second time period at the end stage of the set period. Therefore, during the first time period at the beginning stage and the first time period at the end stage of the set period, the electromagnetic heating device is controlled to operate with the first pulse width, ensuring that the electromagnetic heating device can operate with the first pulse width for a relatively long time within the set period, thereby improving the heating efficiency of the electromagnetic heating device within the set period.

[0032] In a possible design, after controlling the electromagnetic heating device to operate cyclically according to a set period, it further includes: collecting a second voltage value of the electromagnetic heating device; based on the second voltage value reaching a set voltage value, within the set period, controlling the electromagnetic heating device to operate according to a first pulse width, a first duration, a third pulse width, and a second duration; wherein, the third pulse width is less than the second pulse width.

[0033] In this design, during the operation of the electromagnetic heating device, the second voltage value of the electromagnetic heating device is continuously collected. The second voltage value is the operating voltage value during the operation of the electromagnetic heating device according to the second pulse width. When it is detected that the second voltage value during the operation of the electromagnetic heating device according to the second pulse width is greater than the set voltage value, it is determined that the electromagnetic heating device will also generate radiation when operating at the second pulse width during the peak stage of the set period. At this time, by replacing the second pulse width with a third pulse width less than the second pulse width, the electromagnetic heating device is prevented from generating radiation during the voltage peak stage.

[0034] The present invention continuously collects the second voltage value during the operation according to the second pulse width. When it is detected that the second voltage value exceeds the set voltage value, the electromagnetic heating device is immediately controlled to stop operating, avoiding the generation of radiation by the electromagnetic heating device. And by replacing the second pulse width with the third pulse width during the voltage peak stage, that is, by further reducing the operating pulse width of the electromagnetic heating device during the voltage peak stage, the possibility of radiation generated by the operation of the electromagnetic heating device is reduced, and the safety performance of the cooking device during operation is further improved.

[0035] In some embodiments, the value range of the third pulse width is from 5 μs to 6 μs.

[0036] In these embodiments, since the alternating current input to the electromagnetic heating device is at the peak during the continuous operation of the electromagnetic heating device according to the second pulse width, and the second voltage collected during the operation according to the second pulse width is greater than the set voltage, it is determined that there is still a possibility of radiation generation when the electromagnetic heating device operates at the second pulse width. By setting the third pulse width to be less than the second pulse width and controlling the operation of the electromagnetic heating device according to the third pulse width, the electromagnetic heating device can be effectively prevented from generating radiation during the operation at the voltage peak stage.

[0037] In a possible design, within the set period, controlling the electromagnetic heating device to operate according to a first pulse width, a first duration, a third pulse width, and a second duration includes: controlling the electromagnetic heating device to operate at the first pulse width; based on the operation duration of the electromagnetic heating device reaching the first duration, controlling the electromagnetic heating device to operate at the third pulse width for the second duration; controlling the electromagnetic heating device to continuously operate at the first pulse width until reaching the first duration.

[0038] In this design, when the current passes through the zero point, the electromagnetic heating device is controlled to start operating according to the first pulse width, and the operating duration of the electromagnetic heating device is continuously detected. After detecting that the operating duration reaches the first duration, it is determined that if the device continues to operate according to the first pulse width at this time, radiation will be generated, so it continues to operate according to the third pulse width. After detecting that the operating duration of the electromagnetic heating device operating according to the third pulse width reaches the second duration, it is determined that radiation will not be generated even if it continues to operate according to the first pulse width at this time, so it continues to operate according to the first pulse width until the first duration is reached, thereby completing the control of the electromagnetic heating device within the entire set cycle.

[0039] It can be understood that since the first pulse width is greater than the third pulse width, the heating efficiency of the electromagnetic heating device when operating according to the first pulse width is higher than that when operating according to the third pulse width. Therefore, in this application, the electromagnetic heating device is controlled to operate according to the higher first pulse width at both the beginning and the end of the set cycle, ensuring the heating efficiency of the electromagnetic heating device.

[0040] It is worth noting that when the current passes through the zero point, the electromagnetic heating device is controlled to start operating according to the set cycle, that is, the set cycle is the power supply cycle of the alternating current. The operating voltages of the electromagnetic heating device are the same within the first duration at the beginning stage and the second duration at the end stage of the set cycle. Therefore, within the first duration at the beginning stage and the first duration at the end stage of the set cycle, the electromagnetic heating device is controlled to operate according to the first pulse width, ensuring that the electromagnetic heating device can operate according to the first pulse width for a relatively long time within the set cycle, thereby improving the heating efficiency of the electromagnetic heating device within the set cycle.

[0041] According to a second aspect of the present invention, a control device for a cooking device is provided. The cooking device includes an electromagnetic heating device, and the control device includes: an acquisition module for acquiring the first duration, where the first duration is the duration required for the operating voltage value of the electromagnetic heating device to rise to the set voltage value; a determination module for determining the second duration according to the set cycle and the first duration, where the second duration is the duration for the electromagnetic heating device to operate at the second pulse width within the set cycle; and a control module for controlling the operation of the electromagnetic heating device according to the first pulse width, the second pulse width, the first duration, the second duration, and the set cycle; wherein the second pulse width is less than the first pulse width.

[0042] The control device for the cooking device provided by the present invention is used for a cooking device provided with an electromagnetic heating device. The cooking device includes a main body, a cooking cavity, and an electromagnetic heating device. The cooking cavity is arranged within the main body of the cooking device, and the electromagnetic heating device can perform electromagnetic heating on the cooking cavity after being powered on.

[0043] At the beginning stage of cooking, the electromagnetic heating device operates according to the first pulse width, starts timing, and continuously obtains the voltage value during the operation of the electromagnetic heating device. When it is detected that the operating voltage value reaches the set voltage value, the timing is completed to obtain the first duration. It should be noted that when the operating voltage value reaches the set voltage value, it is determined that radiation is generated during the operation of the electromagnetic heating device. Therefore, the first duration is the maximum duration for the electromagnetic heating device to operate according to the first pulse width. Obtain the set period for the electromagnetic heating device to be powered on. Within the set period, the electromagnetic heating device can continuously operate according to the first pulse width until it reaches the first duration. That is, the second duration for the electromagnetic heating device to operate according to the second pulse width can be calculated based on the set period. Since the second pulse width is smaller than the first pulse width, it can ensure that the operating voltage value during the operation of the electromagnetic heating device according to the second pulse width is less than the set voltage value, that is, the electromagnetic heating device does not generate radiation.

[0044] The present invention controls the operation of the electromagnetic heating device, collects the longest operating duration for the electromagnetic heating device to operate according to the first pulse width, that is, the first duration. And calculates the second duration for the electromagnetic heating device to operate based on the set period and the first duration. By controlling the electromagnetic heating device to continuously operate at the larger first pulse width for the first duration, then continuously operate at the smaller second pulse width for the second duration, and then continuously operate at the larger first pulse width for the second duration within a set period. It realizes that the electromagnetic heating device does not generate radiation during operation within the set period, while ensuring that the electromagnetic heating device operates at a larger power, that is, ensuring the heating efficiency of the electromagnetic heating device for the cooking cavity. And it is possible to avoid the electromagnetic heating device from generating radiation without setting a filter in the electromagnetic heating device, reducing the production cost of the cooking device.

[0045] It should be noted that since the power supply of the electromagnetic heating device is selected as the mains power, that is, sinusoidal alternating current. The electromagnetic heating device starts to operate after passing through the zero point, that is, the electromagnetic heating device continuously operates according to the first pulse width until it reaches the first duration. At this time, it has not reached the peak of the alternating current. Control the electromagnetic heating device to continuously operate according to the second pulse width for the second duration. Since the second duration is the duration calculated based on the cycle duration of the alternating current, the electromagnetic heating device is at the peak of the alternating current when operating according to the second pulse width for the second duration. After reaching the second duration, the electromagnetic heating device continues to continuously operate according to the first pulse width for the first duration, that is, the electromagnetic heating device completes the operation of the entire cycle.

[0046] In some embodiments, the value range of the first pulse width is 8 us to 10 us, and the value range of the second pulse width is 6 us to 8 us.

[0047] In these embodiments, since the alternating current input to the electromagnetic heating device is at the peak during the process of the electromagnetic heating device operating according to the second pulse width, setting the second pulse width to be less than the first pulse width can effectively avoid radiation generated during the operation of the electromagnetic heating device at the second pulse width.

[0048] According to a third aspect of the present invention, a control device for a cooking device is provided, including: a memory in which programs or instructions are stored; a processor that executes the programs or instructions stored in the memory to implement the steps of the control method for the cooking device in any possible design in the first aspect. Thus, it has all the beneficial technical effects of the control method for the cooking device in any possible design in the first aspect, and will not be elaborated here too much.

[0049] According to a fourth aspect of the present invention, a readable storage medium is provided. Programs or instructions are stored on the readable storage medium, and when the programs or instructions are executed by a processor, the steps of the control method for the cooking device in any possible design in the first aspect are implemented. Thus, it has all the beneficial technical effects of the control method for the cooking device in any possible design in the first aspect, and will not be elaborated here too much.

[0050] According to a fifth aspect of the present invention, a cooking device is provided, including: the control device for the cooking device defined in the second aspect or the third aspect above, and / or the readable storage medium defined in the fourth aspect above. Thus, it has all the beneficial technical effects of the control device for the cooking device in the second aspect or the third aspect and the readable storage medium defined in the fourth aspect above, and will not be elaborated here too much.

[0051] In addition, the cooking device according to the above technical solution provided by the present invention may further have the following additional technical features:

[0052] In a possible design, the cooking device further includes: a main body; an electromagnetic heating device disposed in the main body; a comparison circuit connected to the electromagnetic heating device for determining the numerical relationship between the operating voltage value of the electromagnetic heating device and the set voltage value; a timing circuit connected to the electromagnetic heating device for timing the operating duration of the electromagnetic heating device.

[0053] In this design, the cooking device includes a main body, an electromagnetic heating device, a comparison circuit, and a timing circuit. A cooking cavity and an installation cavity are provided in the main body, and the electromagnetic heating device is disposed in the installation cavity. After being powered on, the electromagnetic heating device can perform electromagnetic heating on the cooking cavity. The comparison circuit can continuously monitor the operating voltage value of the electromagnetic heating device, and the comparison circuit is provided with a comparison voltage, that is, the set voltage. The timing circuit is used to time the operating duration of the electromagnetic heating device.

[0054] At the beginning stage of cooking, the electromagnetic heating device operates according to the first pulse width, the timing circuit starts timing, and the voltage value during the operation of the electromagnetic heating device is continuously obtained through the comparison circuit. When it is detected that the operating voltage value reaches the set voltage value, the timing circuit completes timing to obtain the first duration. It should be noted that when the operating voltage value reaches the set voltage value, it is determined that radiation is generated during the operation of the electromagnetic heating device. Therefore, the first duration is the maximum duration for the electromagnetic heating device to operate according to the first pulse width. The set period for the electromagnetic heating device to be powered on is obtained. Within the set period, the electromagnetic heating device can continuously operate according to the first pulse width until it reaches the first duration, that is, the second duration for the electromagnetic heating device to operate according to the second pulse width can be calculated based on the set period. Since the second pulse width is smaller than the first pulse width, it can ensure that the operating voltage value during the operation of the electromagnetic heating device according to the second pulse width is less than the set voltage value, that is, the electromagnetic heating device does not generate radiation.

[0055] The present invention controls the operation of the electromagnetic heating device, collects the longest operating duration for the electromagnetic heating device to operate according to the first pulse width, that is, the first duration. And calculates the second duration for the electromagnetic heating device to operate based on the set period and the first duration. By controlling the electromagnetic heating device to first continuously operate at the larger first pulse width for the first duration within a set period, then continuously operate at the smaller second pulse width for the second duration, and then continuously operate at the larger first pulse width for the second duration. It realizes that the electromagnetic heating device does not generate radiation during operation within the set period, while ensuring that the electromagnetic heating device operates at a larger power, that is, ensuring the heating efficiency of the electromagnetic heating device for the cooking cavity. And it can avoid the electromagnetic heating device from generating radiation without setting a filter in the electromagnetic heating device, reducing the production cost of the cooking device.

[0057] In this design, the main body includes a housing, a receiving cavity, an inner pot, a cooking cavity and a lid. A receiving cavity is formed in the housing, the receiving cavity is used to receive the inner pot, and the cooking cavity is formed in the inner pot. After the electromagnetic heating device is powered on, it can perform electromagnetic heating on the cooking cavity in the inner pot. The lid is connected to the housing, and the lid can be buckled on the housing to seal the inner pot.

[0058] During cooking, the food ingredients are placed in the inner pot, the inner pot containing the food ingredients is placed in the receiving cavity of the housing, and the lid is buckled on the inner pot to seal the inner pot. The electromagnetic heating device is controlled to start electromagnetic heating on the food ingredients in the inner pot. When the operation of the electromagnetic heating device reaches the target cooking duration, it is determined that the cooking device has completed cooking the food ingredients, and the electromagnetic heating device is controlled to stop operating.

[0059] It can be understood that the inner pot is detachably connected to the housing, that is, the inner pot can be separately taken out from the accommodating cavity. Before starting cooking, the inner pot is taken out and ingredients are placed in the inner pot. After cooking is completed, the inner pot can be taken out from the accommodating cavity for separate cleaning of the inner pot, achieving the effect of improving the convenience of cleaning the inner pot, simplifying the daily maintenance of the cooking device by the user, and avoiding the problem of dirt accumulation between the inner pot and the housing.

[0060] In a possible design, the cooking device further includes: a first temperature sensor disposed in the accommodating cavity for collecting the temperature value of the inner pot wall; and / or a second temperature sensor disposed on the lid for collecting the temperature value inside the inner pot.

[0081] Step 102, determine the maximum duration for the electromagnetic heating device to operate according to the first pulse width, i.e., the first duration;

[0082] Step 104, calculate the second duration based on the period duration of the set period and the first duration;

[0083] Step 106, control the operation of the electromagnetic heating device according to the set period, the second duration, the first duration, the second pulse width, and the first pulse width.

[0084] The control method of the cooking device provided in this embodiment is used for a cooking device provided with an electromagnetic heating device. The cooking device includes a main body, a cooking cavity, and an electromagnetic heating device. The cooking cavity is arranged inside the main body of the cooking device, and the electromagnetic heating device can perform electromagnetic heating on the cooking cavity after being powered on.

[0085] In the initial stage of cooking, the electromagnetic heating device operates according to the first pulse width, starts timing, and continuously collects the voltage value during the operation of the electromagnetic heating device. When it is detected that the operating voltage value rises to the set voltage value, the timing is completed to obtain the first duration. It should be noted that when the operating voltage value rises to the set voltage value, it is determined that radiation is generated during the operation of the electromagnetic heating device. Therefore, the first duration is the maximum duration during the operation of the electromagnetic heating device according to the first pulse width. Obtain the set period for the electromagnetic heating device to be powered on. Within the set period, the electromagnetic heating device can be controlled to operate according to the first pulse width until the first duration is reached, that is, the second duration of the operation process of the electromagnetic heating device according to the second pulse width can be calculated based on the set period. Since the second pulse width is smaller than the first pulse width, it can be ensured that the operating voltage value during the operation of the electromagnetic heating device according to the second pulse width is less than the set voltage value, that is, the electromagnetic heating device does not generate radiation.

[0086] In this embodiment, during the operation of the electromagnetic heating device, the maximum operating duration that the electromagnetic heating device can sustain when operating according to the first pulse width is collected, that is, the first duration corresponding to the electromagnetic heating device. And calculations are performed based on the set period and the first duration, so that the second duration of the operation of the electromagnetic heating device can be obtained.

[0087] By controlling the electromagnetic heating device to first continuously operate for the first duration according to the larger first pulse width within a set period, then controlling the electromagnetic heating device to operate according to the smaller second pulse width until the second duration is reached, and continuing to control the electromagnetic heating device to operate according to the larger first pulse width until the second duration is reached. It is achieved that within the set period, while the electromagnetic heating device operates without generating radiation, it ensures that the electromagnetic heating device operates at a higher power, that is, it ensures the heating efficiency of the electromagnetic heating device for the cooking cavity. And it is not necessary to set a filter in the electromagnetic heating device to avoid the electromagnetic heating device from generating radiation, reducing the production cost of the cooking device.

[0088] It should be noted that since the power supply of the electromagnetic heating device is selected as the commercial power, that is, sinusoidal alternating current. After the zero-crossing point, the electromagnetic heating device starts to operate, that is, the electromagnetic heating device operates continuously for the first duration according to the first pulse width. At this time, the peak of the alternating current voltage has not been reached. Control the operation device of the electromagnetic heating device to operate continuously for the second duration according to the second pulse width. Since the second duration is the duration calculated according to the cycle duration of the alternating current, the electromagnetic heating device is at the peak of the alternating current when operating according to the second pulse width for the second duration. After reaching the second duration, the electromagnetic heating device continues to operate continuously for the first duration according to the first pulse width, that is, the electromagnetic heating device completes the operation of the entire cycle.

[0089] In some embodiments, the value range of the first pulse width is 8 us to 10 us, and the value range of the second pulse width is 6 us to 8 us.

[0090] In these embodiments, since the alternating current input to the electromagnetic heating device is at the peak during the process of the electromagnetic heating device operating continuously according to the second pulse width, setting the second pulse width smaller than the first pulse width can effectively avoid the electromagnetic heating device generating radiation during the operation according to the second pulse width.

[0091] As Figure 2 shown, in any of the above embodiments, determining the maximum duration, that is, the first duration, of the electromagnetic heating device operating according to the first pulse width includes:

[0092] Step 202, when the electromagnetic heating device is at the zero-crossing point of the current, control the electromagnetic heating device according to the first pulse width;

[0093] Step 204, obtain the first voltage value;

[0094] Step 206, when it is detected that the first voltage value rises to the set voltage value, control the electromagnetic heating device to stop operating, and collect the first duration of the heating device operation.

[0095] In this embodiment, an alternating current is input to the electromagnetic heating device to power on and operate the electromagnetic heating device. When the alternating current input to the battery heating device reaches the zero crossing point, the electromagnetic heating device is controlled to start operating according to the first pulse width. After the electromagnetic heating device starts operating, the first voltage value during the operation of the electromagnetic heating device is collected. Since the alternating current input to the electromagnetic heating device is a sinusoidal alternating current, the operating voltage value is in a continuously increasing state. When it is detected that the first voltage value is equal to the set voltage value, the electromagnetic heating device is shut down. During the process of controlling the operation of the electromagnetic heating device according to the first pulse width, the operation duration is continuously timed to determine the first duration, that is, starting from the zero crossing point of the current, the electromagnetic heating device is controlled to operate according to the first pulse width. If the operation duration of the electromagnetic heating device does not reach the first duration, the electromagnetic heating device will not generate radiation.

[0096] In this embodiment, by controlling the electromagnetic heating device to start operating when the alternating current reaches the zero crossing point, the period of the alternating current is made to coincide with the set period during the operation of the electromagnetic heating device, and the first duration of the electromagnetic heating device operating according to the first pulse width is timed, improving the accuracy of the obtained first duration. Thus, it is possible to control the operation of the electromagnetic heating device according to the first pulse width for the first duration, ensuring that the electromagnetic heating device does not generate radiation. Since the first pulse width is a relatively high pulse width, the operating power of the electromagnetic heating device is increased on the premise of ensuring that the electromagnetic heating device does not generate radiation.

[0097] It can be understood that when the electromagnetic heating device operates at the set voltage value, the electromagnetic heating device will generate radiation. By controlling the electromagnetic heating device to operate at a voltage lower than the set voltage value, it is possible to avoid the electromagnetic heating device generating radiation during the heating operation.

[0098] In any of the above embodiments, calculating the second duration according to the period duration of the set period and the first duration includes:

[0099] Obtain the period duration of the set period, and perform a subtraction operation on the period duration and twice the first duration to determine the second duration.

[0100] In this embodiment, the total duration of the set period is a fixed duration, and the first duration is the operation duration of the electromagnetic heating device operating according to the first pulse width within the set period. Since the power supply of the electromagnetic heating device is selected as the commercial power, that is, a sinusoidal alternating current. The process of the electromagnetic heating device continuously operating according to the second pulse width is set at the peak of the alternating current voltage. Therefore, by performing a subtraction operation on the period duration of the set period and twice the first duration, the second duration is obtained.

[0101] At the beginning of the set period, that is, through the zero-crossing point of the current, control the electromagnetic heating device to operate according to the first pulse width. After the operation duration reaches the first duration, control the electromagnetic heating device to operate according to the second pulse width for the second duration, and then control the electromagnetic heating device to operate according to the first pulse width for the first duration, so as to complete the adjustment of the pulse width of the electromagnetic heating device within one period.

[0102] In this embodiment, by controlling the electromagnetic heating device to operate at a lower second pulse width at the voltage peak, it is possible to avoid the generation of radiation during the operation of the electromagnetic heating device as the supply voltage increases. And during the remaining time of the period, control the electromagnetic heating device to operate at a higher first pulse width. While ensuring the heating efficiency of the electromagnetic heating device, it avoids the generation of radiation by the electromagnetic heating device.

[0103] As Figure 3 shown, in any of the above embodiments, controlling the electromagnetic heating device to operate according to the set period, the second duration, the second pulse width, the first duration, and the first pulse width includes:

[0104] Step 302, control the electromagnetic heating device to perform cyclic operation according to the set period;

[0105] Step 304, during the set period of operation, control the operation of the electromagnetic heating device according to the second duration, the second pulse width, the first pulse width, and the first duration.

[0106] In this embodiment, the electromagnetic heating device operates in a cycle according to the set period, that is, after the electromagnetic heating device completes one operation with this set period, it continues to operate with the set period. During the operation of the set period, the electromagnetic heating device first operates continuously according to the first pulse width until it reaches the first duration, then operates according to the second pulse width for the second duration, and then continues to operate continuously according to the first pulse width until it reaches the first duration, so as to complete the operation within one set period. After completing the operation of one set period, it starts to operate with the set period again.

[0107] During the first duration at the beginning of the set period and the first duration before the end of the set period, control the operation of the electromagnetic heating device according to the larger first pulse width, so as to ensure the heating power of the electromagnetic heating device within the set period. During the voltage peak section of the set period, control the operation of the electromagnetic heating device according to the smaller first pulse width, avoiding the problem of radiation generated by the electromagnetic heating device under a higher voltage. The electromagnetic heating device does not generate radiation within the set period, so by controlling the electromagnetic heating device to operate in a cycle according to the set period, the stable operation of the electromagnetic heating device is achieved.

[0108] As Figure 4As shown above, in any of the above embodiments, controlling the operation of the electromagnetic heating device according to the second duration, the second pulse width, the first pulse width, and the first duration includes:

[0109] Step 402, controlling the operation of the electromagnetic heating device according to the first pulse width;

[0110] Step 404, when the operation duration reaches the first duration, controlling the operation of the electromagnetic heating device according to the second pulse width;

[0111] Step 406, when the operation duration reaches the second duration, controlling the operation of the electromagnetic heating device according to the first pulse width.

[0112] In this embodiment, at the current zero-crossing point, start controlling the operation of the electromagnetic heating device according to the first pulse width, continuously detect the operation duration of the electromagnetic heating device. After detecting that the operation duration reaches the first duration, it is determined that radiation will be generated if continuing to operate according to the first pulse width at this time, then continue to operate according to the second pulse width. After detecting that the operation duration of the electromagnetic heating device operating according to the second pulse width reaches the second duration, it is determined that no radiation will be generated if continuing to operate according to the first pulse width at this time, then continue to operate according to the first pulse width until the first duration is reached, thereby completing the control of the electromagnetic heating device within the entire set cycle.

[0113] It can be understood that since the first pulse width is greater than the second pulse width, the heating efficiency of the electromagnetic heating device when operating according to the first pulse width is higher than that when operating according to the second pulse width. Therefore, in this application, by controlling the operation of the electromagnetic heating device according to the higher first pulse width at both the start stage and the end stage of the set cycle, the heating efficiency of the electromagnetic heating device is ensured.

[0114] It is worth noting that at the current zero-crossing point, start controlling the operation of the electromagnetic heating device according to the set cycle, making the set cycle match the power supply cycle of the alternating current.

[0115] During the first duration at the start stage of the set cycle and the second duration at the end stage, the operating voltage of the electromagnetic heating device is the same. Therefore, during the first duration at the start stage and the first duration at the end stage of the set cycle, control the electromagnetic heating device to operate according to the first pulse width, ensuring that the electromagnetic heating device can operate according to the first pulse width for a long time within the set cycle, thereby improving the heating efficiency of the electromagnetic heating device within the set cycle.

[0116] Such as Figure 5 As shown above, in any of the above embodiments, after controlling the electromagnetic heating device to operate cyclically according to the set cycle, it further includes:

[0117] Step 502, continuously obtaining the second voltage value;

[0118] Step 504, when it is detected that the second voltage value rises to the set voltage value, during the set period of operation, control the electromagnetic heating device to operate according to the second duration, the third pulse width, the first pulse width, and the first duration.

[0119] Among them, the second pulse width is greater than the third pulse width.

[0120] In this embodiment, during the operation of the electromagnetic heating device, continuously collect the second voltage value during the operation of the electromagnetic heating device. The second voltage value is the operating voltage value during the operation of the electromagnetic heating device according to the second pulse width. When it is detected that the second voltage value of the electromagnetic heating device operating according to the second pulse width is greater than the set voltage value, it is determined that radiation will also be generated when controlling the operation of the electromagnetic heating device according to the second pulse width during the peak stage of the set period. At this time, by replacing the second pulse width with a third pulse width smaller than the second pulse width, the electromagnetic heating device is prevented from generating radiation during the voltage peak stage.

[0121] In this embodiment, by continuously collecting the second voltage value during the operation according to the second pulse width, when it is detected that the second voltage value exceeds the set voltage value, immediately control the electromagnetic heating device to stop, to avoid the electromagnetic heating device from generating radiation. And by replacing the second pulse width with the third pulse width to operate during the voltage peak stage, that is, by further reducing the operating pulse width of the electromagnetic heating device during the voltage peak stage, the possibility of the electromagnetic heating device generating radiation during operation is reduced, and the safety performance of the cooking device during operation is further improved.

[0122] In some embodiments, the value range of the third pulse width is 5 μs to 6 μs.

[0123] In these embodiments, since during the continuous operation of the electromagnetic heating device according to the second pulse width, the alternating current input to the electromagnetic heating device is at the peak, and the second voltage collected during the operation according to the second pulse width is greater than the set voltage, it is determined that there is still a possibility of generating radiation when controlling the operation of the electromagnetic heating device according to the second pulse width. Setting the third pulse width to be smaller than the second pulse width and controlling the operation of the electromagnetic heating device according to the third pulse width can effectively prevent the electromagnetic heating device from generating radiation during the operation at the voltage peak stage.

[0124] As Figure 6 shown, in any of the above embodiments, controlling the electromagnetic heating device to operate according to the second duration, the third pulse width, the first pulse width, and the first duration includes:

[0125] Step 602, control the operation of the electromagnetic heating device according to the first pulse width;

[0126] Step 604, when the operation duration reaches the first duration, control the operation of the electromagnetic heating device according to the third pulse width;

[0127] Step 606, when the operation duration reaches the second duration, control the operation of the electromagnetic heating device according to the first pulse width.

[0128] In this embodiment, at the zero-crossing point of the current, control the electromagnetic heating device to start operating according to the first pulse width, continuously detect the operation duration of the electromagnetic heating device. After detecting that the operation duration reaches the first duration, determine that if it continues to operate according to the first pulse width at this time, radiation will be generated, then continue to operate according to the third pulse width. After detecting that the operation duration of the electromagnetic heating device operating according to the third pulse width reaches the second duration, determine that if it continues to operate according to the first pulse width at this time, no radiation will be generated either, then continue to operate according to the first pulse width until reaching the first duration, thereby completing the control of the electromagnetic heating device within the entire set period.

[0129] It can be understood that since the first pulse width is greater than the third pulse width, the heating efficiency of the electromagnetic heating device when operating according to the first pulse width is higher than that when operating according to the third pulse width. Therefore, in this application, by controlling the operation of the electromagnetic heating device according to the higher first pulse width at both the start stage and the end stage of the set period, the heating efficiency of the electromagnetic heating device is ensured.

[0130] It should be noted that at the zero-crossing point of the current, start to control the operation of the electromagnetic heating device according to the set period, so that the set period is consistent with the power supply period of the alternating current.

[0131] During the first duration at the start stage of the set period and the third duration at the end stage, the operating voltage of the electromagnetic heating device is the same. Therefore, during the first duration at the start stage of the set period and the first duration at the end stage, control the electromagnetic heating device to operate according to the first pulse width, ensuring that the electromagnetic heating device can operate according to the first pulse width for a long time within the set period, thereby improving the heating efficiency of the electromagnetic heating device within the set period.

[0132] Embodiment 2:

[0133] As Figure 7 shown, in the second embodiment of the present invention, a control device 700 of a cooking device is provided, and an electromagnetic heating device is arranged in the cooking device.

[0134] The control device 700 of the cooking device includes:

[0135] An acquisition module 702, configured to determine the maximum duration for the electromagnetic heating device to operate according to the first pulse width, that is, the first duration;

[0136] A determination module 704, configured to calculate the second duration according to the period duration of the set period and the first duration;

[0137] A control module 706, which operates according to a set period, a second duration, a first duration, a second pulse width, and a first pulse width, controls the operation of the electromagnetic heating device.

[0138] The control device of the cooking device provided in this embodiment is used for a cooking device provided with an electromagnetic heating device. The cooking device includes a main body, a cooking cavity, and an electromagnetic heating device. The cooking cavity is arranged inside the main body of the cooking device, and the electromagnetic heating device can perform electromagnetic heating on the cooking cavity after being powered on.

[0139] In the initial stage of cooking, the electromagnetic heating device operates according to the first pulse width, starts timing, and continuously collects the voltage value during the operation of the electromagnetic heating device. When it is detected that the operating voltage value rises to the set voltage value, the timing is completed to obtain the first duration. It should be noted that when the operating voltage value rises to the set voltage value, it is determined that radiation is generated during the operation of the electromagnetic heating device. Therefore, the first duration is the maximum duration during the operation of the electromagnetic heating device according to the first pulse width. Obtain the set period for the electromagnetic heating device to be powered on. Within the set period, the electromagnetic heating device can be controlled to operate according to the first pulse width until the first duration is reached, that is, the second duration of the operation of the electromagnetic heating device according to the second pulse width can be calculated according to the set period. Since the second pulse width is smaller than the first pulse width, it can ensure that the operating voltage value during the operation of the electromagnetic heating device according to the second pulse width is less than the set voltage value, that is, the electromagnetic heating device will not generate radiation.

[0140] In this embodiment, during the operation of the electromagnetic heating device, the maximum operating duration that the electromagnetic heating device can sustain when operating according to the first pulse width is collected, that is, the first duration corresponding to the electromagnetic heating device. And it is calculated according to the set period and the first duration, so that the second duration of the continuous operation of the electromagnetic heating device can be obtained.

[0141] By controlling the electromagnetic heating device to first continuously operate according to the larger first pulse width for the first duration within a set period, then control the electromagnetic heating device to operate according to the smaller second pulse width until the second duration of continuous operation, and continue to control the electromagnetic heating device to operate according to the larger first pulse width until the second duration of continuous operation. It realizes that within the set period, the electromagnetic heating device will not generate radiation during operation, while ensuring that the electromagnetic heating device operates at a larger power, that is, ensuring the heating efficiency of the electromagnetic heating device for the cooking cavity. And there is no need to set a filter in the electromagnetic heating device to avoid the electromagnetic heating device from generating radiation, reducing the production cost of the cooking device.

[0142] It should be noted that since the power supply of the electromagnetic heating device is selected as the commercial power, that is, sinusoidal alternating current. The electromagnetic heating device starts to operate after the zero crossing point, that is, the electromagnetic heating device operates continuously for the first duration according to the first pulse width. At this time, the peak of the alternating current voltage has not been reached. The control electromagnetic heating device operating device operates continuously for the second duration according to the second pulse width. Since the second duration is the duration calculated according to the period duration of the alternating current, the electromagnetic heating device is at the peak of the alternating current when operating according to the second pulse width for the second duration. After reaching the second duration, the electromagnetic heating device continues to operate continuously for the first duration according to the first pulse width, that is, the electromagnetic heating device completes the operation of the entire cycle.

[0143] In some embodiments, the value range of the first pulse width is from 8 us to 10 us, and the value range of the second pulse width is from 6 us to 8 us.

[0144] In these embodiments, since the alternating current input to the electromagnetic heating device is at the peak during the process of the electromagnetic heating device operating continuously according to the second pulse width, setting the second pulse width to be smaller than the first pulse width can effectively avoid the electromagnetic heating device generating radiation during the operation with the second pulse width.

[0145] In any of the above embodiments, the control module 706 is further configured to control the electromagnetic heating device according to the first pulse width when the electromagnetic heating device is at the zero crossing point of the current;

[0146] The acquisition module 702 is further configured to acquire the first voltage value;

[0147] The acquisition module is further configured to control the electromagnetic heating device to stop operating and acquire the first duration of the heating device operation when it detects that the first voltage value rises to the set voltage value.

[0148] In this embodiment, the electromagnetic heating device is powered on and operated by inputting alternating current to the electromagnetic heating device. When the alternating current input to the battery heating device reaches the zero crossing point, the electromagnetic heating device is controlled to start operating according to the first pulse width. After the electromagnetic heating device starts to operate, the first voltage value during the operation of the electromagnetic heating device is acquired. Since the alternating current input to the electromagnetic heating device is sinusoidal alternating current, the operating voltage value is in a continuously increasing state. When it is detected that the first voltage value is equal to the set voltage value, the electromagnetic heating device is stopped. During the process of controlling the operation of the electromagnetic heating device according to the first pulse width, the operation duration is continuously timed to determine the first duration, that is, starting from the zero crossing point of the current, the electromagnetic heating device is controlled to operate according to the first pulse width. When the operation duration of the electromagnetic heating device does not reach the first duration, the electromagnetic heating device will not generate radiation.

[0149] In this embodiment, the electromagnetic heating device is controlled to start operating when the alternating current reaches the zero crossing point, so that the period of the alternating current coincides with the set period during the operation of the electromagnetic heating device, and the first duration during which the electromagnetic heating device operates according to the first pulse width is timed, improving the accuracy of the obtained first duration. Thus, control is achieved during the process of the electromagnetic heating device operating for the first duration according to the first pulse width, ensuring that the electromagnetic heating device does not generate radiation. Since the first pulse width is a relatively high pulse width, the operating power of the electromagnetic heating device is increased on the premise of ensuring that the electromagnetic heating device does not generate radiation.

[0150] It can be understood that when the electromagnetic heating device operates at the set voltage value, the electromagnetic heating device will generate radiation. By controlling the electromagnetic heating device to operate at a voltage less than the set voltage value, it is possible to avoid the electromagnetic heating device generating radiation during the heating operation.

[0151] In any of the above embodiments, the acquisition module 702 is further configured to acquire the period duration of the set period, perform a subtraction operation on the period duration and twice the first duration, and determine the second duration.

[0152] In this embodiment, the total duration of the set period is a fixed duration, and the first duration is the operating duration during which the electromagnetic heating device operates according to the first pulse width within the set period. Since the power supply of the electromagnetic heating device is selected as the commercial power, that is, sinusoidal alternating current. The process of the electromagnetic heating device continuously operating according to the second pulse width is set at the peak of the alternating current voltage. Therefore, by performing a subtraction operation on the period duration of the set period and twice the first duration, the second duration is obtained.

[0153] At the beginning stage of the set period, that is, after the zero crossing of the current, the electromagnetic heating device is controlled to operate according to the first pulse width. After the operating duration reaches the first duration, the electromagnetic heating device is controlled to operate according to the second pulse width for the second duration, and then the electromagnetic heating device is controlled to continuously operate according to the first pulse width for the first duration, thereby completing the adjustment of the pulse width of the electromagnetic heating device within one period.

[0154] In this embodiment, by controlling the electromagnetic heating device to operate at a lower second pulse width at the voltage peak, it is possible to avoid the electromagnetic heating device generating radiation during operation due to the increase in the supply voltage. And the electromagnetic heating device is controlled to operate at a higher first pulse width during the remaining time of the period. While ensuring the heating efficiency of the electromagnetic heating device, it avoids the electromagnetic heating device generating radiation.

[0155] In any of the above embodiments, the control module 706 is further configured to control the electromagnetic heating device to perform cyclic operation according to the set period;

[0156] The control module 706 is further configured to control the operation of the electromagnetic heating device according to a second duration, a second pulse width, a first pulse width, and a first duration in a set period during operation.

[0157] In this embodiment, the electromagnetic heating device operates in a cyclic manner according to a set period, that is, after the electromagnetic heating device completes an operation in this set period, it continues to operate according to the set period. During the operation in the set period, the electromagnetic heating device first operates continuously according to the first pulse width until it reaches the first duration, then operates according to the second pulse width for the second duration, and then continues to operate continuously according to the first pulse width until it reaches the first duration, so as to complete the operation within a set period. After completing the operation within a set period, it starts to operate again according to the set period.

[0158] During the first duration at the beginning stage of the set period and the first duration before the end of the set period, the operation of the electromagnetic heating device is controlled according to the larger first pulse width, so as to ensure the heating power of the electromagnetic heating device within the set period. During the voltage peak section of the set period, the operation of the electromagnetic heating device is controlled according to the smaller first pulse width, avoiding the problem of radiation generated by the electromagnetic heating device at a higher voltage. The electromagnetic heating device does not generate radiation within the set period. Therefore, by controlling the electromagnetic heating device to operate in a cyclic manner according to the set period, the stable operation of the electromagnetic heating device is realized.

[0159] In any of the above embodiments, the control module 706 is further configured to control the operation of the electromagnetic heating device according to the first pulse width;

[0160] The control module 706 is further configured to control the operation of the electromagnetic heating device according to the second pulse width when the operation duration reaches the first duration;

[0161] The control module 706 is further configured to control the operation of the electromagnetic heating device according to the first pulse width when the operation duration reaches the second duration.

[0162] In this embodiment, at the zero-crossing of the current, the operation of the electromagnetic heating device is started to be controlled according to the first pulse width, and the operation duration of the electromagnetic heating device is continuously detected. After detecting that the operation duration reaches the first duration, if it is determined that radiation will be generated if the operation continues according to the first pulse width at this time, then the operation continues according to the second pulse width. After detecting that the operation duration of the electromagnetic heating device operating according to the second pulse width reaches the second duration, if it is determined that radiation will not be generated if the operation continues according to the first pulse width at this time, then the operation continues according to the first pulse width until it reaches the first duration, so as to complete the control of the electromagnetic heating device within the entire set period.

[0163] It can be understood that since the first pulse width is greater than the second pulse width, the heating efficiency of the electromagnetic heating device when operating according to the first pulse width is higher than that of the electromagnetic heating device when operating according to the second pulse width. Therefore, in the present application, by controlling the operation of the electromagnetic heating device according to the higher first pulse width at both the start stage and the end stage of the set period, the heating efficiency of the electromagnetic heating device is ensured.

[0164] It is worth noting that at the zero-crossing point of the current, the control of the operation of the electromagnetic heating device starts according to the set period, so that the set period conforms to the power supply period of the alternating current.

[0165] During the first duration in the start stage and the second duration in the end stage of the set period, the operating voltage of the electromagnetic heating device is the same. Therefore, during the first duration in the start stage and the first duration in the end stage of the set period, the electromagnetic heating device is controlled to operate according to the first pulse width, ensuring that the electromagnetic heating device can operate according to the first pulse width for a long time within the set period, thereby improving the heating efficiency of the electromagnetic heating device within the set period.

[0166] In any of the above embodiments, the acquisition module 702 is further configured to continuously acquire the second voltage value;

[0167] The control module 706 is further configured to, when detecting that the second voltage value rises to the set voltage value, control the operation of the electromagnetic heating device according to the second duration, the third pulse width, the first pulse width, and the first duration during the set period of operation.

[0168] Wherein, the second pulse width is greater than the third pulse width.

[0169] In this embodiment, during the operation of the electromagnetic heating device, the second voltage value during the operation of the electromagnetic heating device is continuously collected. The second voltage value is the operating voltage value during the operation of the electromagnetic heating device according to the second pulse width. When detecting that the second voltage value of the electromagnetic heating device operating according to the second pulse width is greater than the set voltage value, it is determined that radiation will also be generated when controlling the operation of the electromagnetic heating device according to the second pulse width at the peak stage of the set period. At this time, by replacing the second pulse width with the third pulse width smaller than the second pulse width, radiation generated by the electromagnetic heating device at the voltage peak stage is avoided.

[0170] In this embodiment, by continuously collecting the second voltage value during the operation according to the second pulse width, when detecting that the second voltage value exceeds the set voltage value, the electromagnetic heating device is immediately controlled to stop, avoiding radiation generated by the electromagnetic heating device. And by replacing the second pulse width with the third pulse width to operate at the voltage peak stage, that is, by further reducing the operating pulse width of the electromagnetic heating device at the voltage peak stage, the possibility of radiation generated during the operation of the electromagnetic heating device is reduced, and the safety performance of the cooking device during operation is further improved.

[0171] In some embodiments, the value range of the third pulse width is from 5 μs to 6 μs.

[0172] In these embodiments, since the alternating current input to the electromagnetic heating device is at the peak during the process of the electromagnetic heating device operating continuously according to the second pulse width, and the second voltage collected when operating according to the second pulse width is greater than the set voltage, it is determined that there is still a possibility of generating radiation when controlling the operation of the electromagnetic heating device according to the second pulse width. Setting the third pulse width to be less than the second pulse width and controlling the operation of the electromagnetic heating device according to the third pulse width can effectively avoid the generation of radiation during the operation of the electromagnetic heating device at the voltage peak stage.

[0173] In any of the above embodiments, the control module 706 is further configured to control the operation of the electromagnetic heating device according to the first pulse width;

[0174] The control module 706 is further configured to control the operation of the electromagnetic heating device according to the third pulse width when the operation duration reaches the first duration;

[0175] The control module 706 is further configured to control the operation of the electromagnetic heating device according to the first pulse width when the operation duration reaches the second duration.

[0176] In this embodiment, when the current passes through the zero point, the electromagnetic heating device is controlled to start operating according to the first pulse width, and the operation duration of the electromagnetic heating device is continuously detected. After detecting that the operation duration reaches the first duration, it is determined that radiation will be generated if the operation continues according to the first pulse width, then the operation continues according to the third pulse width. After detecting that the operation duration of the electromagnetic heating device operating according to the third pulse width reaches the second duration, it is determined that radiation will not be generated if the operation continues according to the first pulse width, then the operation continues according to the first pulse width until the first duration is reached, thereby completing the control of the electromagnetic heating device within the entire set cycle.

[0177] It can be understood that since the first pulse width is greater than the third pulse width, the heating efficiency of the electromagnetic heating device when operating according to the first pulse width is higher than that when operating according to the third pulse width. Therefore, in this application, by controlling the operation of the electromagnetic heating device according to the higher first pulse width at both the beginning stage and the end stage of the set cycle, the heating efficiency of the electromagnetic heating device is ensured.

[0178] It is worth noting that when the current passes through the zero point, the control of the operation of the electromagnetic heating device starts according to the set cycle, so that the set cycle is consistent with the power supply cycle of the alternating current.

[0179] During the first time period at the start stage and the third time period at the end stage of the set period, the operating voltage of the electromagnetic heating device is the same. Therefore, during the first time period at the start stage and the first time period at the end stage of the set period, the electromagnetic heating device is controlled to operate according to the first pulse width, ensuring that the electromagnetic heating device can operate according to the first pulse width for a relatively long time within the set period, thereby improving the heating efficiency of the electromagnetic heating device within the set period.

[0183] The processor 804 executes the programs or instructions stored in the memory 802 to implement the steps of the control method of the cooking device in Embodiment One, and thus has all the beneficial technical effects of the control method of the cooking device in Embodiment One, and will not be elaborated here too much.

[0185] In the fourth embodiment of the present invention, a readable storage medium is provided, on which a program is stored. When the program is executed by a processor, it implements the control method of the cooking device in any of the above embodiments, and thus has all the beneficial technical effects of the control method of the cooking device in any of the above embodiments.

[0186] Among them, the readable storage medium is, for example, a read-only memory (ROM), a random access memory (RAM), a magnetic disk, or an optical disc, etc.

[0187] Embodiment Five:

[0188] In the fifth embodiment of the present invention, a cooking device is provided, including: the control device of the cooking device defined in Embodiment Two or Embodiment Three above, and / or the readable storage medium defined in Embodiment Four above, and thus has all the beneficial technical effects of the control device of the cooking device in Embodiment Two or Embodiment Three above and the readable storage medium defined in Embodiment Four above, and will not be elaborated here too much.

[0189] In any of the above embodiments, the cooking device includes a main body, an electromagnetic heating device, a comparison circuit, and a timing circuit.

[0190] The electromagnetic heating device is installed on the main body;

[0191] The comparison circuit is connected to the electromagnetic heating device, and the comparison circuit is used to determine the numerical relationship between the operating voltage value and the set voltage value of the electromagnetic heating device;

[0192] The timing circuit is connected to the electromagnetic heating device, and the timing circuit is used to time the operating duration of the electromagnetic heating device.

[0193] In this embodiment, the cooking device includes a main body, an electromagnetic heating device, a comparison circuit and a timing circuit. A cooking cavity and an installation cavity are arranged in the main body, and the electromagnetic heating device is arranged in the installation cavity. After being powered on, the electromagnetic heating device can perform electromagnetic heating on the cooking cavity. The comparison circuit can continuously monitor the operating voltage value of the electromagnetic heating device, and the comparison circuit is provided with a comparison voltage, that is, the set voltage. The timing circuit is used to time the operating duration of the electromagnetic heating device.

[0194] In the initial stage of cooking, the electromagnetic heating device operates according to the first pulse width, and the timing circuit starts timing. The voltage value during the operation of the electromagnetic heating device is continuously obtained through the comparison circuit. When it is detected that the operating voltage value rises to the set voltage value, the timing circuit completes timing to obtain the first duration. It should be noted that when the operating voltage value rises to the set voltage value, it is determined that radiation is generated during the operation of the electromagnetic heating device. Therefore, the first duration is the maximum duration for the electromagnetic heating device to operate according to the first pulse width. The set period of power-on of the electromagnetic heating device is obtained. Within the set period, the electromagnetic heating device can continuously operate according to the first pulse width until reaching the first duration, that is, the second duration for the electromagnetic heating device to operate according to the second pulse width can be calculated according to the set period. Since the second pulse width is smaller than the first pulse width, it can be ensured that the operating voltage value during the operation of the electromagnetic heating device according to the second pulse width is less than the set voltage value, that is, the electromagnetic heating device does not generate radiation.

[0195] In this embodiment, by controlling the operation of the electromagnetic heating device, the longest operating duration for the electromagnetic heating device to operate according to the first pulse width, that is, the first duration, is collected. And the second duration of the operation of the electromagnetic heating device is calculated according to the set period and the first duration. By controlling the electromagnetic heating device to first continuously operate at a larger first pulse width for the first duration within a set period, then continuously operate at a smaller second pulse width for the second duration, and then continuously operate at a larger first pulse width for the second duration. It is realized that the electromagnetic heating device does not generate radiation during operation within the set period, while ensuring that the electromagnetic heating device operates at a larger power, that is, ensuring the heating efficiency of the electromagnetic heating device for the cooking cavity. And there is no need to set a filter in the electromagnetic heating device to avoid radiation generated by the electromagnetic heating device, reducing the production cost of the cooking device.

When the electromagnetic heating device runs for the target cooking duration, it is determined that the cooking device has completed cooking the food ingredients, and the electromagnetic heating device is controlled to stop running.

[0202] It can be understood that the inner pot is detachably connected to the housing, that is, the inner pot can be taken out of the receiving cavity alone.
