Technical Field

[0001] The present application relates to the technical field of electric stove control, and in particular to an electric stove control method, device and electric stove. Background Art

[0002] Traditional cooking stoves typically use gas stoves and induction cookers. Gas stoves pose safety risks such as gas poisoning, while induction cookers can cause uneven heating. Electric stoves, on the other hand, use plasma technology to convert electrical energy into heat, generating flames by ionizing air, thus enabling open-flame cooking. Electric stoves eliminate the need for fuels like gas and instead use electricity to generate flames, transforming traditional combustion methods. Because they don't require gas, they eliminate the root cause of gas explosions. Compared to gas and induction cookers, electric stoves are safer, more convenient, and don't compromise the user's cooking experience.

[0044] The electric stove control method provided by the present application can be applied to, for example Figure 1In the application environment shown. Among them, the induction cooker includes a processor 102, a sensing module 104, and an induction cooker circuit 106; the processor 102 is respectively connected to the induction cooker circuit 106 and the sensing module 104.

The sensing module 104 can be used to collect the current sensing and acquisition data of the induction cooker circuit 106. The processor 102 can be used to obtain the current sensing and acquisition data of the induction cooker circuit 106; when the current sensing and acquisition data is higher than a preset threshold, a first power control signal is transmitted to the induction cooker circuit 106 until the current sensing and acquisition data is lower than the preset threshold, and a second power control signal is transmitted to the induction cooker circuit 106; wherein, the first power control signal is used to instruct the induction cooker circuit 106 to output an output power based on a preset decreasing rule value; the second power control signal is used to instruct the induction cooker circuit 106 to output a preset fixed value of output power; the maximum value of the preset decreasing rule value is less than the preset fixed value, so as to optimize the induction cooker control method and improve the reliability and safety of the induction cooker control.

[0045] In one embodiment, as Figure 2 shown, a method for controlling an induction cooker is provided. Taking the processor in Figure 1 as an example, the method includes the following steps:

[0046] Step S210, obtaining the current sensing and acquisition data of the induction cooker circuit.

[0047] Among them, the induction cooker circuit generates flames by electricity during operation, and then can heat the cookware above the stove head. The sensing and acquisition data can be, but is not limited to, the output power data, working current data, and heat dissipation temperature data of the induction cooker circuit.

[0048] Exemplarily, after the induction cooker is powered on and started, the user can operate the ignition switch to make the induction cooker circuit perform the ignition operation. During the normal ignition operation of the induction cooker circuit, the sensing module can collect the current sensing and acquisition data of the induction cooker circuit in real time, and transmit the collected current sensing and acquisition data to the processor. Further, during the normal ignition operation of the induction cooker circuit, the processor can obtain the current sensing and acquisition data of the induction cooker circuit.

[0049] Step S220: When the currently sensed and collected data is higher than the preset threshold, transmit a first power control signal to the induction cooker circuit until the currently sensed and collected data is lower than the preset threshold, and then transmit a second power control signal to the induction cooker circuit. The first power control signal is used to instruct the induction cooker circuit to output an output power based on a preset decreasing rule value, and the second power control signal is used to instruct the induction cooker circuit to output a preset fixed value. The maximum value of the preset decreasing rule value is less than the preset fixed value.

[0050] Among them, the preset threshold can be set according to the data type of the currently sensed and collected data. For example, when the currently sensed and collected data is output power data, the preset threshold is set to the threshold corresponding to the power; when the currently sensed and collected data is working current data, the preset threshold is set to the threshold corresponding to the current; when the currently sensed and collected data is heat dissipation temperature data, the preset threshold is set to the threshold corresponding to the temperature.

[0051] The first power control signal can be used to instruct the induction cooker circuit to output an output power based on a preset decreasing rule value. For example, the first power control signal can be a power control signal with an adjustable frequency. The second power control signal can be used to instruct the induction cooker circuit to output a preset fixed value. For example, the second power control signal can be a power control signal with a fixed frequency. The first power control signal can be an adjustable frequency PFM (Pulse Frequency Modulation) square wave signal, and the second power control signal can be a fixed frequency PFM square wave signal.

[0052] Exemplarily, the preset decreasing rule can be set to decrease at intervals of 300 W (watts) of power value within a preset time period. For example, when the induction cooker circuit is normally ignited and working, the output power is 1500 W. When the induction cooker circuit receives the first power control signal, the induction cooker circuit controls the output power to decrease to 1200 W, 900 W, 700 W, etc. in sequence based on a 5S (second) time interval. The preset fixed value can be set to the output power value when the induction cooker circuit is normally ignited and working.

[0053] Exemplarily, the processor may compare and process the acquired current sensing and acquisition data with a preset threshold to determine whether the current sensing and acquisition data is within the normal range. When the current sensing and acquisition data is higher than the preset threshold, a first power control signal is transmitted to the electric stove circuit, so that the electric stove circuit outputs an output power based on a preset decreasing rule value according to the first power control signal, so that the output power of the electric stove circuit slowly decreases, avoiding electric stove failures when the current sensing and acquisition data is not within the normal range. During the process of controlling the electric stove circuit to slowly decrease the output power, the processor continuously acquires the current sensing and acquisition data and continues to determine whether the current sensing and acquisition data is within the normal range. If the current sensing and acquisition data is still not within the normal range, the electric stove circuit is controlled to slowly decrease the output power to the minimum value. Until the acquired current sensing and acquisition data is lower than the preset threshold, a second power control signal is transmitted to the electric stove circuit, so that the electric stove circuit outputs an output power based on a preset fixed value according to the second power control signal, thereby enabling the output power of the electric stove circuit to recover to the preset fixed value, enabling the electric stove circuit to resume normal ignition operation, thus optimizing the electric stove control method and improving the reliability and safety of the electric stove control.

[0054] In the above embodiment, by acquiring the current sensing and acquisition data of the electric stove circuit; when the current sensing and acquisition data is higher than the preset threshold, a first power control signal is transmitted to the electric stove circuit until the current sensing and acquisition data is lower than the preset threshold, and a second power control signal is transmitted to the electric stove circuit; wherein, the first power control signal is used to instruct the electric stove circuit to output an output power based on a preset decreasing rule value; the second power control signal is used to instruct the electric stove circuit to output a preset fixed value of output power; the maximum value of the preset decreasing rule value is less than the preset fixed value, realizing the safety control of the electric stove. In this application, during the operation of the electric stove, the current sensing and acquisition data of the electric stove circuit is monitored in real time, and it is judged whether the acquired current sensing and acquisition data is within the normal range. When it is detected that the current sensing and acquisition data is higher than the preset threshold, a first power control signal is transmitted to the electric stove circuit, so that the stove circuit outputs an output power based on a preset decreasing rule value according to the first power control signal until it is detected that the current sensing and acquisition data is lower than the preset threshold, and a second power control signal is transmitted to the electric stove circuit, so that the electric stove circuit outputs a preset fixed value of output power according to the second power control signal, realizing the safe operation of the electric stove, thus optimizing the electric stove control method and improving the reliability and safety of the electric stove control.

[0055] In one example, the sensing and acquisition data includes heat dissipation temperature data. As Figure 3 shown, a method for controlling an electric stove is provided. Taking the method applied to the Figure 1 processor therein as an example for illustration, it includes the following steps:

[0056] Step S310, obtain the current sensing and acquisition data of the induction cooker circuit; the sensing and acquisition data includes heat dissipation temperature data.

[0057] Step S320, when the current heat dissipation temperature data is higher than the preset temperature threshold, transmit a first power control signal to the induction cooker circuit until the current heat dissipation temperature data is lower than the preset temperature threshold, and then transmit a second power control signal to the induction cooker circuit; wherein, the first power control signal is used to instruct the induction cooker circuit to output an output power based on a preset decreasing rule value; the second power control signal is used to instruct the induction cooker circuit to output a preset fixed value of output power; the maximum value of the preset decreasing rule value is less than the preset fixed value.

[0058] Among them, the current heat dissipation temperature data can be obtained by collecting the heat dissipation temperature of the induction cooker circuit through a temperature sensor.

[0059] Exemplarily, the temperature sensor is connected to the processor. When the induction cooker is powered on and started, the user can operate the ignition switch to make the induction cooker circuit perform the ignition operation. During the normal ignition operation of the induction cooker circuit, the temperature sensor can collect the current heat dissipation temperature data of the induction cooker circuit in real time and transmit the collected current heat dissipation temperature data to the processor. Furthermore, during the normal ignition operation of the induction cooker circuit, the processor can obtain the current heat dissipation temperature data of the induction cooker circuit.

[0060] The processor compares the obtained current heat dissipation temperature data with the preset temperature threshold to determine whether the current heat dissipation temperature data is within the normal range. If the current heat dissipation temperature data is higher than the preset temperature threshold, a first power control signal is transmitted to the induction cooker circuit, so that the induction cooker circuit outputs an output power based on a preset decreasing rule value according to the first power control signal, so that the output power of the induction cooker circuit slowly decreases, avoiding induction cooker failures when the current heat dissipation temperature data is not within the normal range. During the process of controlling the induction cooker circuit to slowly reduce the output power, the processor obtains the current heat dissipation temperature data in real time until the obtained current heat dissipation temperature data is lower than the preset temperature threshold, and then transmits a second power control signal to the induction cooker circuit, so that the induction cooker circuit outputs an output power based on a preset fixed value according to the second power control signal, thereby making the output power of the induction cooker circuit return to the preset fixed value, making the induction cooker circuit resume normal ignition operation, thereby optimizing the induction cooker control method and improving the reliability and safety of induction cooker control.

[0061] In one example, the sensing and acquisition data includes working current data. As Figure 4 shown, a method for controlling an induction cooker is provided. Taking the method applied to the Figure 1 processor as an example for illustration, the method includes the following steps:

[0062] Step S410, obtain the currently sensed acquisition data of the induction cooker circuit; the sensed acquisition data includes operating current data.

[0063] Step S420, when the currently acquired operating current data is higher than a preset current threshold, transmit a first power control signal to the induction cooker circuit until the currently acquired operating current data is lower than the preset current threshold, and then transmit a second power control signal to the induction cooker circuit; wherein, the first power control signal is used to instruct the induction cooker circuit to output an output power based on a preset decreasing rule value; the second power control signal is used to instruct the induction cooker circuit to output a preset fixed value of output power; the maximum value of the preset decreasing rule value is less than the preset fixed value.

[0064] Among them, the currently acquired operating current data can be obtained by the current sensor collecting the operating current of the induction cooker circuit.

[0065] Exemplarily, the current sensor is connected to the processor. After the induction cooker is started up, the user can operate the ignition switch to make the induction cooker circuit perform the ignition operation. During the normal ignition operation of the induction cooker circuit, the current sensor can collect the currently acquired operating current data of the induction cooker circuit in real time and transmit the currently acquired operating current data to the processor. Furthermore, during the normal ignition operation of the induction cooker circuit, the processor can obtain the currently acquired operating current data of the induction cooker circuit.

[0066] The processor compares the currently acquired operating current data with the preset current threshold for processing to determine whether the currently acquired operating current data is within the normal range. If the currently acquired operating current data is higher than the preset current threshold, a first power control signal is transmitted to the induction cooker circuit, so that the induction cooker circuit outputs an output power based on a preset decreasing rule value according to the first power control signal, so that the output power of the induction cooker circuit slowly decreases, avoiding induction cooker failures when the currently acquired operating current data is not within the normal range. During the process of controlling the induction cooker circuit to slowly decrease the output power, the processor obtains the currently acquired operating current data in real time until the currently acquired operating current data is lower than the preset current threshold, and then transmits a second power control signal to the induction cooker circuit, so that the induction cooker circuit outputs an output power based on a preset fixed value according to the second power control signal, thereby making the output power of the induction cooker circuit return to the preset fixed value, making the induction cooker circuit resume normal ignition operation, thus optimizing the induction cooker control method and further improving the reliability and safety of the induction cooker control.

[0067] In one example, the sensed acquisition data includes output power data. As Figure 5 shown, a method for controlling an induction cooker is provided. Taking the method applied to the Figure 1 processor as an example for illustration, it includes the following steps:

[0068] Step S510, obtain the current sensing and acquisition data of the induction cooker circuit; the sensing and acquisition data includes output power data.

[0069] Step S520, when the current output power data is higher than the preset power threshold, transmit a first power control signal to the induction cooker circuit until the current output power data is lower than the preset power threshold, and then transmit a second power control signal to the induction cooker circuit; wherein, the first power control signal is used to instruct the induction cooker circuit to output an output power based on a preset decreasing rule value; the second power control signal is used to instruct the induction cooker circuit to output a preset fixed value; the maximum value of the preset decreasing rule value is less than the preset fixed value.

[0070] Among them, the current output power data can be obtained by a power sensor collecting the output power of the induction cooker circuit.

[0071] Exemplarily, the power sensor is connected to the processor. When the induction cooker is started up, the user can operate the ignition switch to make the induction cooker circuit perform the ignition operation. During the normal ignition operation of the induction cooker circuit, the power sensor can collect the current output power data of the induction cooker circuit in real time and transmit the collected current output power data to the processor. Further, during the normal ignition operation of the induction cooker circuit, the processor can obtain the current output power data of the induction cooker circuit.

[0072] The processor compares and processes the obtained current output power data with the preset power threshold to determine whether the current output power data is within the normal range. If the current output power data is higher than the preset power threshold, a first power control signal is transmitted to the induction cooker circuit, so that the induction cooker circuit outputs an output power based on the preset decreasing rule value according to the first power control signal, so that the output power of the induction cooker circuit slowly decreases, avoiding induction cooker failures when the current output power data is not within the normal range. During the process of controlling the induction cooker circuit to slowly reduce the output power, the processor obtains the current output power data in real time. Until the obtained current output power data is lower than the preset power threshold, a second power control signal is transmitted to the induction cooker circuit, so that the induction cooker circuit outputs an output power based on the preset fixed value according to the second power control signal, and then the output power of the induction cooker circuit is restored to the preset fixed value, so that the induction cooker circuit resumes normal ignition operation, thereby optimizing the induction cooker control method and further improving the reliability and safety of induction cooker control.

[0073] It should be noted that the processor may include an A / D data conversion subroutine. When the processor performs the power-on self-check program, it can detect the analog signals of each sensing module (including the power sensor, current sensor, and temperature sensor) in real time through the A / D data conversion subroutine, including the output power analog signal, operating current analog signal, and heat dissipation temperature analog signal. The analog signals are converted into digital signals through the A / D data conversion subroutine for the processor to judge and process, so as to execute the corresponding action task processing.

[0074] In one example, after the step of transmitting the first power control signal to the induction cooker circuit, it includes:

[0075] Generating first display information and transmitting the first display information to the display module so that the display module displays the first display information.

[0076] Among them, the first display information can be corresponding fault code information such as E01, E03, E05, etc.

[0077] The processor judges whether the currently acquired sensing and acquisition data is within the normal range. If the currently acquired sensing and acquisition data is higher than the preset threshold, a first power control signal is transmitted to the induction cooker circuit, so that the induction cooker circuit outputs an output power based on a preset decreasing rule value according to the first power control signal, so that the output power of the induction cooker circuit slowly decreases, avoiding induction cooker failures when the currently acquired sensing and acquisition data is not within the normal range; at the same time, the first display information is displayed through the display module, so as to facilitate the user to observe the fault code information of the induction cooker and facilitate the maintenance of the induction cooker.

[0078] Furthermore, during the process of controlling the induction cooker circuit to slowly reduce the output power, the processor continuously acquires the currently acquired sensing and acquisition data in real time and continues to judge whether the currently acquired sensing and acquisition data is within the normal range. Until the currently acquired sensing and acquisition data is lower than the preset threshold, a second power control signal is transmitted to the induction cooker circuit, so that the induction cooker circuit outputs an output power based on a preset fixed value according to the second power control signal, so that the output power of the induction cooker circuit is restored to the preset fixed value, so that the induction cooker circuit resumes normal ignition operation, and at the same time, the current output power information of the induction cooker circuit is displayed in real time through the display module, thereby optimizing the control method of the induction cooker and improving the control reliability and safety of the induction cooker.

[0079] Exemplarily, when the current heat dissipation temperature data is higher than the preset temperature threshold, a first power control signal is transmitted to the induction cooker circuit, so that the induction cooker circuit outputs an output power based on a preset decreasing rule value according to the first power control signal, and at the same time, the display module displays the E01 fault code information. When the current working current data is higher than the preset current threshold, a first power control signal is transmitted to the induction cooker circuit, so that the induction cooker circuit outputs an output power based on a preset decreasing rule value according to the first power control signal, and at the same time, the display module displays the E03 fault code information. When the current output power data is higher than the preset power threshold, a first power control signal is transmitted to the induction cooker circuit, so that the induction cooker circuit outputs an output power based on a preset decreasing rule value according to the first power control signal, and at the same time, the display module displays the E05 fault code information. Furthermore, according to the display of different fault code information, it is convenient for users to observe the fault types of the induction cooker and to repair the induction cooker.

[0080] In one embodiment, as Figure 6 shown, a method for controlling an induction cooker is provided. Taking the processor in Figure 1 as an example for illustration, the method includes the following steps:

[0081] Step S610, obtaining the current sensing and acquisition data of the induction cooker circuit.

[0082] Step S620, when the current sensing and acquisition data is higher than the preset threshold, transmitting a first power control signal to the induction cooker circuit until the current sensing and acquisition data is lower than the preset threshold, and then transmitting a second power control signal to the induction cooker circuit; wherein, the first power control signal is used to instruct the induction cooker circuit to output an output power based on a preset decreasing rule value; the second power control signal is used to instruct the induction cooker circuit to output a preset fixed value of output power; the maximum value of the preset decreasing rule value is less than the preset fixed value.

[0083] Among them, the specific content and process of the above steps S610 and S620 can refer to the above content and will not be elaborated here.

[0084] Step S630, when it is detected that the cookware leaves the induction cooker hob, calculating the first duration for the cookware to leave the induction cooker hob.

[0085] Step S640, if the first duration is greater than the preset time threshold, controlling the induction cooker circuit to stop outputting power, and transmitting second display information to the display module so that the display module displays the second display information.

[0086] Among them, the preset time threshold can be obtained according to the system preset. For example, the preset time threshold can be set to 30S (seconds). The second display information can be corresponding fault code information such as C01, C02, etc. Exemplarily, an infrared sensor or a distance sensor can be used to detect whether the cookware has left the cooking hob of the induction cooker.

[0087] For example, after the induction cooker is powered on and started, the user can operate the ignition switch to make the induction cooker circuit perform the ignition operation. During the normal ignition operation of the induction cooker circuit, the distance sensor can detect the state of the cookware in real time. When it is detected that the cookware has left the cooking hob of the induction cooker, the timer is triggered, and then the first duration for which the cookware has left the cooking hob of the induction cooker is calculated. When the first duration is greater than the preset time threshold, the induction cooker circuit is controlled to stop outputting power, so that the induction cooker stops the ignition operation, and the second display information is transmitted to the display module, and the fault code of the second display information is displayed through the display module. Thus, when the cookware is not above the cooking hob of the induction cooker for a long time, the induction cooker circuit can be automatically turned off, and at the same time, according to the displayed corresponding fault code information, it is convenient for the user to observe the fault type of the induction cooker and convenient for repairing the induction cooker.

[0088] Further, when the first duration is greater than 30S, the induction cooker circuit is controlled to stop outputting power, so that the induction cooker stops the ignition operation, and the C02 fault code information is transmitted to the display module, and the C02 fault code is displayed through the display module; when the first duration is less than 30S and greater than, the induction cooker circuit is controlled to stop outputting power, so that the induction cooker stops the ignition operation, and the C01 fault code information is transmitted to the display module, and the C01 fault code is displayed through the display module. Thus, according to the displayed corresponding fault code information, it is convenient for the user to observe the fault type of the induction cooker and convenient for repairing the induction cooker.

[0089] In one example, the induction cooker control method further includes the step of: after the induction cooker circuit has been operating normally for a preset operating time, setting the maximum output power of the induction cooker circuit to a limited output power; the limited output power is less than the maximum output power.

[0090] During the normal ignition operation of the induction cooker circuit, if the continuous normal operating time reaches the preset operating time, then the maximum output power of the induction cooker circuit is set to the limited output power. For example, the maximum output power is 2500W and the limited output power is 1800W. By limiting the maximum output power of the induction cooker circuit that has been operating for a long time, the safety of the induction cooker can be further improved.

[0091] Exemplarily, during the normal ignition operation of the electric stove circuit, if the continuous normal operation time reaches 0.5 hours, the maximum output power of the electric stove circuit is set to 1800W; if the continuous normal operation time reaches 1 hour, the electric stove circuit is controlled to stop the ignition operation, and at the same time, the F01 fault code information is displayed through the display module, so as to prevent the electric stove from working at a high power state for a long time, further optimizing the control method of the electric stove and improving the control reliability and safety of the electric stove.

[0092] It should be noted that during the normal ignition operation of the electric stove circuit, the user can adjust the power value set by the ignition switch (such as a potentiometer), call the PFM frequency modulation processing task, and each power value corresponds to a corresponding frequency. After starting the PFM frequency modulation program, the encoded data in the function is output by the processor and converted into a PFM square wave output, so as to drive the corresponding voltage output of the switching power supply circuit in the electric stove circuit, realizing the adjustment of the output power of the electric stove circuit, that is, realizing the adjustment of the output firepower of the electric stove.

[0093] It should be understood that although Figures 2-6 the steps in the flowchart of Figures 2-6 are shown in sequence according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise clearly stated in this article, the execution of these steps has no strict order limit, and these steps can be executed in other orders. Moreover,

[0094] In one embodiment, as Figure 7 shown, a control device for an electric stove is provided, including:

[0095] A data acquisition unit 710, configured to acquire the current sensing acquisition data of the electric stove circuit.

[0096] A power control unit 720, configured to transmit a first power control signal to the electric stove circuit when the current sensing acquisition data is higher than a preset threshold, and transmit a second power control signal to the electric stove circuit until the current sensing acquisition data is lower than the preset threshold; wherein, the first power control signal is used to instruct the electric stove circuit to output an output power based on a preset decreasing rule value; the second power control signal is used to instruct the electric stove circuit to output a preset fixed value of output power; the maximum value of the preset decreasing rule value is less than the preset fixed value.

[0097] For the specific limitations of the electric stove control device, reference may be made to the limitations of the electric stove control method in the above text, which will not be elaborated here. Each module in the above electric stove control device can be implemented in whole or in part by software, hardware, and their combinations. The above modules can be embedded in or independent of the processor in the electric stove in the form of hardware, or stored in the memory in the electric stove in the form of software, so as to facilitate the controller to call and execute the operations corresponding to each of the above modules.

[0098] In one embodiment, as Figure 8 shown, an electric stove is further provided.

[0099] Among them, the electric stove circuit 810 may include a switching power supply circuit, a boost circuit, and an ion needle assembly; the boost circuit is electrically connected between the switching power supply circuit and the ion needle assembly.

[0100] In one example, when the processor 830 executes a computer program, the following steps can be implemented:

[0101] By obtaining the current sensing acquisition data of the electric stove circuit 810; when the current sensing acquisition data is higher than a preset threshold, transmitting a first power control signal to the electric stove circuit 810 until the current sensing acquisition data is lower than the preset threshold, and then transmitting a second power control signal to the electric stove circuit 810; wherein, the first power control signal is used to instruct the electric stove circuit 810 to output an output power based on a preset decreasing rule value; the second power control signal is used to instruct the electric stove circuit 810 to output a preset fixed value of output power; the maximum value of the preset decreasing rule value is less than the preset fixed value, so as to realize the safety control of the electric stove.

[0102] In the above embodiments, during the operation of the electric stove, the current sensing and acquisition data of the electric stove circuit are monitored in real time, and it is judged whether the currently obtained sensing and acquisition data is within the normal range. When it is detected that the currently obtained sensing and acquisition data is higher than the preset threshold, a first power control signal is transmitted to the electric stove circuit, so that the stove circuit outputs an output power based on the preset decreasing rule value according to the first power control signal until it is detected that the currently obtained sensing and acquisition data is lower than the preset threshold, and a second power control signal is transmitted to the electric stove circuit, so that the electric stove circuit outputs an output power with a preset fixed value, realizing the safe operation of the electric stove, thereby optimizing the control mode of the electric stove and improving the control reliability and safety of the electric stove.
