[0024] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the drawings, wherein the same or similar reference numbers represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present application, and cannot be understood as a limitation of the present application.

[0025] Please refer to Figures 1 to 3 The embodiment of the present application discloses a multi-coil electromagnetic cooker 100. The multi-coil electromagnetic cooker 100 includes an electromagnetic cooker control circuit 10, a display control board 20 and a plurality of power drive boards 30. The display control board 20 is in communication connection with the plurality of power drive boards 30 through the electromagnetic cooker control circuit 10.

[0026] The electromagnetic cooker control circuit 10 is used to identify the communication addresses of the plurality of power drive boards 30 and output identification signals.

[0027] It can be understood that one display control board 20 in the multi-coil electromagnetic cooker 100 of the present application respectively communicates with the plurality of power drive boards 30, and one display control board 20 respectively controls the output of the plurality of power drive boards 30. Each power drive board 30 has a corresponding communication address. Therefore, the electromagnetic cooker control circuit 10 of the present application can identify the corresponding communication addresses of different power drive boards 30, thereby identifying different power drive boards 30.

[0028] The identification signal can be an electrical signal that transmits the communication address of the power drive board 30 identified. The communication address can be represented by letters, numbers or other symbols, which are not limited here. For example, the power drive board 30 includes power drive board A and power drive board B. The communication address of the power drive board A identified by the electromagnetic cooker control circuit 10 can be Addr1, and the communication address of the power drive board B identified by the electromagnetic cooker control circuit 10 can be Addr2.

[0029] After the electromagnetic range control circuit 10 outputs the identification signal, the display control panel 20 receives the identification signal and outputs a driving signal to simultaneously drive multiple power driving panels 30 to work. That is, the display control panel 20 of the present application can receive the identification signal with the communication address corresponding to different power driving panels 30, and simultaneously drive multiple different power driving panels 30 to work according to the identification signal.

[0030] That is, the present application determines the unique communication address of different power driving panels 30, and different power driving panels 30 can use the same control program and burning file in the display control panel 20, which reduces the production and maintenance cost, effectively solves the error-prone problem in the production and burning of power driving panels 30, and improves the production efficiency.

[0031] In summary, the display control panel 20 of the multi-line disc electromagnetic range of the present application can determine the communication address corresponding to multiple power driving panels 30, and multiple power driving panels 30 can communicate with the display control panel 20 through the electromagnetic range control circuit 10. Different power driving panels 30 can use a unified program and burning file, which reduces the production and maintenance cost, simplifies the control program of the power driving panel 30, effectively solves the error-prone problem in the production and burning of power driving panels 30, and improves the production efficiency.

[0032] Specifically, the electromagnetic range control circuit 10 of the present application includes an address recognition port 101 and a signal output port 102. The electromagnetic range control circuit 10 recognizes the communication address of the power driving panel 30 through the address recognition port 101, outputs the identification signal to the display control panel 20, so that the display control panel 20 outputs the corresponding driving signal. The electromagnetic range control circuit 10 outputs the driving signal to the power driving panel 30 through the signal output port 11.

[0033] For example, as shown in Figure 2 or Figure 3 The address recognition port 101 is the port shown as SWDIO UTX, and the signal output port 102 is the port shown as SWCLK UPX.

[0034] In detail, when the system is powered on, the power driving panel 30 first configures the port RX1 connected with SWDIO UTX as a port input mode, which can read the level state of the SWDIO UTX port, so as to recognize the communication address of the power driving panel 30 according to the read level state of the SWDIO UTX port.

[0035] In one embodiment, one display control board is connected with two power drive boards simultaneously, and the two power drive boards are power drive board A and power drive board B respectively. The port voltage of SWDIO UTX in the power drive board A is pulled up to 5V through the resistor R0, and the SWDIO UTX port in the power drive board B is grounded through the resistor R5, so when the system is powered on, the power drive board A and the power drive board B first configure the SWDIO UTX port into the port input mode, and the level state of the SWDIO UTX port can be read. Since the power drive board A is pulled up to 5V through R0, the level signal read is high, and the SWDIO UTX port in the power drive board B is grounded, so the level signal read is low.

[0036] That is, the application can identify whether the power drive board 30 is welded with the resistor R0 through the electromagnetic cooker control circuit 10 on the printed circuit board, so as to determine whether the communication address of the power drive board A and the power drive board B is 0 or 1.

[0037] If the electromagnetic cooker control circuit 10 identifies that the communication address of the power drive board A is 0, the communication address 0 of the power drive board A is sent to the display control board 20 during data transmission, and if the electromagnetic cooker control circuit 10 identifies that the communication address of the power drive board B is 1, the communication address 1 of the power drive board B is sent to the display control board 20 during data transmission.

[0038] Then, the display control board 20 can output the driving signal corresponding to the power drive board 30 according to the identification signal, so that different power drive boards 30 are driven by the same operation program of the display control board 20.

[0039] In this way, the multi-line disc electromagnetic cooker of the application can identify and confirm the unique communication address of different power drive boards 30 through the electromagnetic cooker control circuit 10, and the display control board 20 can use the same operation program according to the communication address, share one burning file, and improve the production efficiency.

[0040] In some embodiments, referring to Figure 2 or Figure 3 , the electromagnetic cooker control circuit 10 includes a first control circuit 11 and a second control circuit 12, and each power drive board 30 is connected with the display control board 20 through the corresponding first control circuit 11 and the second control circuit 12. The first control circuit 11 includes an address identification port 101, and the second control circuit 12 includes a signal output port 102. The first control circuit 11 identifies the communication address of the power drive board 30 through the address identification port 101, and outputs an identification signal to the display control board 20. The second control circuit 12 is used for outputting a driving signal to the corresponding power drive board 30 through the signal output port 102.

[0041] That is to say, the electromagnetic range control circuit 10 has two branches, the first control circuit 11 is used to identify the communication address of different power drive boards 30, so as to send different identification signals with different communication addresses to the display control board 20, so that the display control board 20 receives the identification signal and outputs the drive signal to drive the multiple power drive boards 30 to work at the same time.

[0042] It can be understood that the first control circuit 11 further comprises an identification output port 103, and the second control circuit 12 further comprises a drive input port 104. The first control circuit 11 outputs the identification signal to the display control board 20 through the identification output port 103. The second control circuit 12 receives the drive signal input by the display control board 20 through the drive input port 104.

[0043] Please refer to Figure 2 , the identification output port 103 can be the TXDO port in Figure 2 , and the drive input port 104 can be the RXDO port in Figure 2 .

[0044] In this way, the first control circuit 11 can output the identification signal to the display control board 20 through the identification output port 103, and the second control circuit 12 can receive the drive signal input by the display control board 20 through the drive input port 104, so that the electromagnetic range control circuit 10 can continuously identify the identification signal and output the drive signal to the corresponding power circuit board 30 in time.

[0045] In one embodiment, the display control board 20 receives the identification signal and outputs the drive signal to the power drive board 30 through the second control circuit 12 to control the corresponding power drive board 30 to work. The drive signal can be an electrical signal, specifically a voltage signal or a current signal. That is, the display control board 20 can control the power drive board 30 to work through the second control circuit 12.

[0046] In detail, in one embodiment, the power drive board 30 comprises a first power drive board 31 and a second power drive board 32, and the identification signal comprises a first signal and a second signal. As Figure 2 or Figure 3As shown, the first control circuit 11 of the first power drive board 31 includes the first resistor R0, and the first resistor R0 is connected in parallel to the first control circuit 11. The first control circuit 11 identifies the first communication address of the first power drive board 31 through the address identification port 101, and outputs the first signal. The first control circuit 11 of the second power drive board 32 does not include the first resistor R0. The first control circuit 11 identifies the second communication address of the second power drive board 32 through the address identification port 101, and outputs the second signal. That is, the first signal is an electrical signal carrying the first communication address, and the second signal is an electrical signal carrying the second communication address.

[0047] The first resistor R0 can be an adjustable resistor or a resistor with a fixed resistance value, which is not limited herein. For example, the first resistor R0 is a resistor with a fixed resistance value of 5V, and the first signal is a voltage signal of about 5V. If the first resistor R0 is an adjustable resistor, when the first resistor R0 is adjusted to a preset resistance value, the corresponding first signal is a voltage signal corresponding to the preset resistance value.

[0048] The electromagnetic cooker control circuit 10 of the present application can be configured as a control circuit connected with the first resistor R0 according to the corresponding power drive board 30, or configured as a control circuit without the first resistor R0 according to the corresponding power drive board 30. Thus, after the display control board 20 is electrically connected with the power drive board 30, the address identification port 101 of the electromagnetic cooker control circuit 10 can identify different power drive boards 30 and obtain the communication addresses of different power drive boards 30.

[0049] It should be noted that the structures and connection relationships of other resistors and transistors of the electromagnetic cooker control circuit 10 of the present application, except the first resistor R0, are as shown in Figure 2 or Figure 3 .

[0050] In this way, the electromagnetic cooker control circuit 10 of the present application can make the display control board 20 connected with the first power drive board 31 and the second power drive board 32 through two first control circuits 11. The display control board 20 can obtain the communication addresses of the first power drive board 31 and the second power drive board 32 through the electromagnetic cooker control circuit 10, so that the two power drive boards 30 can use a unified program and burning file in the display control board 20, which reduces the production and maintenance costs, simplifies the control program of the power drive board 30, effectively solves the problem of easy errors in the production and burning of the power drive board 30, and improves the production efficiency.

[0051] In some embodiments, the first signal is a high-level signal and the second signal is a low-level signal. That is, for example, when the electromagnetic range control circuit 10 identifies that a certain power driving board 30 generates a high-level signal, the communication address of the power driving board 30 can be classified as "1"; when the electromagnetic range control circuit 10 identifies that a certain power driving board 30 generates a low-level signal, the communication address of the power driving board 30 can be classified as "0".

[0052] Therefore, the application can determine the communication address of the power driving board 30 by determining whether the identification signal is a high-level signal or a low-level signal, so that the communication address can be input to the same operation program of the display control board 20, and the multiple power driving boards 30 driven and controlled can work, without each power driving board 30 having a separate control program in the display control board 20. The control program of the power driving board 30 is simplified, the problem of easy error in production and burning of the power driving board 30 is effectively solved, and the production efficiency is improved.

[0053] In some embodiments of the application, the display control board 20 includes a signal reading module, and a preset operation program is burned in the control chip of the display control board 20. The display control board 20 reads the communication address in the identification signal through the signal reading module, and inputs the communication address into the preset operation program for operation to output the corresponding driving signal.

[0054] That is, the preset operation program can be a program burned in the control chip in advance, which can be operated according to the communication address of the power driving board 30 in the identification signal to issue the corresponding driving signal to the corresponding power driving board 30.

[0055] In this way, the application can input the communication address to the preset operation program of the display control board 20, and the multiple power driving boards 30 driven and controlled can work, without each power driving board 30 having a separate control program in the display control board 20. The control program of the power driving board 30 is simplified, the problem of easy error in production and burning of the power driving board 30 is effectively solved, and the production efficiency is improved.

[0056] In some embodiments, the display control board 20 further includes multiple signal output modules, and the display control board 20 outputs multiple driving signals through the multiple signal output modules. That is, the display control board 20 of the application can output multiple driving signals to multiple power driving boards 30 through multiple signal output modules to synchronously drive multiple power driving boards 30 to work, which is convenient and fast.

[0057] The application also discloses a household appliance. The household appliance includes the multi-wire disc electromagnetic range described in the above embodiments.

[0058] Thus, the display control panel 20 in the multi-wire disc electromagnetic range of the household appliance can determine the communication addresses corresponding to the plurality of power drive panels 30, the plurality of power drive panels 30 communicate with the display control panel 20 through the electromagnetic range control circuit 10, different power drive panels 30 can use a unified program and a burning file, the production and maintenance costs are reduced, the control program of the power drive panel 30 is simplified, the problem that the production and burning of the power drive panel 30 are prone to errors can be effectively solved, and the production efficiency is improved.

[0059] The above embodiments only express several implementation manners of the utility model, the description is more specific and detailed, but it cannot be understood as the limitation of the utility model patent range. It should be pointed out that for ordinary skilled persons in the art, without departing from the utility model concept, a number of modifications and improvements can be made, which belong to the protection range of the utility model. Therefore, the protection range of the utility model patent should be subject to the appended claims.
