Communication transfer electric control boards, household appliance and household appliance control system

Abstract

The invention provides communication transfer electric control boards, a household appliance and a household appliance control system. A communication transfer electric control board comprises an interface circuit which is used for accessing a Wi-Fi communication module and carrying out data instruction interaction with the Wi-Fi communication module, wherein a data instruction is configured as aninstruction capable of being analyzed by the Wi-Fi communication module; and a control circuit which is used for converting the data instruction and a control instruction, wherein the control instruction is configured as the instruction capable of being performed by the household appliance, and the control instruction is also configured to feed back an operation state of the household appliance.The data instruction sent by the Wi-Fi communication module is transmitted to the household appliance through the interface circuit and the control circuit in sequence. The control instruction sent bythe household appliance is transmitted to the Wi-Fi communication module through the control circuit and the interface circuit in sequence. Through application of the technical scheme provided by theinvention, a conventional air conditioner can be modified with low cost in the short term, the air conditioner is enabled to have a Wi-Fi communication function, a communication mode is expanded, andcommunication reliability and use experience are improved.

Description

technical field [0001] The invention relates to the technical field of household electrical appliances, in particular to a communication switching electric control board, a household electrical appliance and a household electrical appliance control system. Background technique [0002] Home appliances such as air conditioners, electric fans, vacuum cleaners, purifiers, home monitoring, audio-visual equipment, kitchen utensils, and refrigerators have become indispensable products for people. With the rapid development of artificial intelligence technology, smart home appliances are being Developed Wi-Fi (Wireless Fidelity, wireless local area network based on IEEE 802.11b standard) communication function. On the one hand, Wi-Fi communication has a wide coverage (Wi-Fi communication radius can reach 100 meters), and the communication quality and anti-interference On the other hand, the highest bandwidth of Wi-Fi communication can reach 11Mbps. At the same time, the bandwidth c...

AI Technical Summary

Problems solved by technology

[0003] In related technologies, traditional home appliances usually do not have a Wi-Fi communication module, and can only interact with the remote control device through infrared communication, or receive user instructions through a touch panel. Since the power supply of the Wi-Fi communication module is usually 3.3V, while the power supply of the motherboard of traditional home appliances is usually 5V, the Wi-Fi communication module and the motherboard of traditional home appliances cannot communicate directly. Therefore, if the Wi-Fi communication function of traditional home appliances needs to be developed, then It is necessary to redevelop the main board circuit of the home appliance, which leads to high cost of transformation and long debugging cycle
