However, this communication method, on the one hand, the contact resistance of the connecting wires generated during installation, and the aging problem of the connecting wires during use, will cause abnormal communication signals; on the other hand, in some application scenarios, the installation space of the heating control circuit board and the display control circuit board needs to be independently sealed for waterproofing or insect-proofing, and cannot be directly connected. The above communication method cannot meet new application requirements.

[0045] In order to solve the above problems, the utility model proposes a cooking utensil circuit board assembly, referring to Figures 1 to 5 In one embodiment, the cooking appliance circuit board assembly comprises:

[0046] The system main control circuit 10 is used to receive the control signal sent by the user;

[0047] The heating control circuit 20 is used to receive the control signal sent by the system main control circuit 10 and work according to the received control signal;

[0050] In this embodiment, the system main control circuit 10 and the heating control circuit 20 can be arranged on different circuit boards, and the communication connection between the system main control circuit 10 and the heating control circuit 20 is realized through the wireless communication module 30. Among them, the system main control circuit 10 can be realized by using a system main control chip or a microprocessor such as MCU, FPGA, CPLD, etc., which is used to receive the control instruction sent by the user through the input component, and send the control instruction to the heating control circuit 20 through the wireless communication circuit, so that the heating control circuit 20 works according to the received control instruction, and controls the display component to display the corresponding working information, such as the inner pot temperature, steam temperature, working current, working voltage and other working parameters. The heating control circuit 20 can also be realized by using an electromagnetic heating control chip or a microprocessor such as MCU, FPGA, CPLD, etc., which is used to control the operation of the IGBT switch circuit and other circuits according to the control instruction sent by the system main control circuit 10, so as to realize functions such as starting heating, stopping heating, and keeping warm, and sending the corresponding communication signal to the system main control circuit 10 through the wireless communication circuit, so that the system main control circuit 10 controls the display component to display the corresponding working information.

[0051] The wireless communication module 30 is arranged between the system main control circuit 10 and the heating control circuit 20, and is used to realize the wireless communication connection between the system main control circuit 10 and the heating control circuit 20.

The wireless communication module 30 can be specifically composed of a first wireless communication circuit 31 and a second wireless communication circuit 32. For example, the user sends a control signal for starting heating to the system main control circuit 10 through an input component that can realize user input such as a button or a touch panel, and the system main control circuit 10 sends the control signal for starting heating to the heating control circuit 20 through the wireless communication module 30. When the heating control circuit 20 receives the control signal for starting heating, it controls the operation of circuits such as the IGBT switch circuit to realize the function of heating the cooking utensils. Specifically, the wireless communication module 30 may include two wireless communication circuits, one wireless communication circuit is connected to the system main control circuit 10, and the other wireless communication circuit is connected to the heating control circuit 20, and a wireless communication connection is established between the two wireless communication circuits to achieve a wireless communication connection between the system main control circuit 10 and the heating control circuit 20. It can be understood that the above-mentioned wireless communication circuit can be an independent module, or it can be integrated in the system main control circuit 10 and the heating control circuit 20, and the wireless communication circuit can be set on the same circuit board as the system main control circuit 10 or the heating control circuit 20, or it can be set on a separate circuit board.

[0052] The utility model realizes the communication connection between the system main control circuit 10 and the heating control circuit 20 by setting the wireless communication module 30, so that the communication connection between the system main control circuit 10 and the heating control circuit 20 does not need to be realized through connecting cables, thereby eliminating the structural redundancy caused by too many wires and the problem of being unable to ensure the security of information transmission, and improving the stability of communication between the system main control circuit 10 and the heating control circuit 20. In addition, through the wireless communication module 30, the communication connection between the system main control circuit 10 and the heating control circuit 20 does not need to be realized through connecting cables, so that the circuit boards carrying the system main control circuit 10 and the heating control circuit 20 can be independently sealed to meet different application scenarios.
