Features and functions Compared with traditional household appliances, smart appliances have the following characteristics: 1 Network function. Various smart home appliances can be connected together through a home LAN, and can also be connected to manufacturers' service sites through a home gateway interface. Ultimately, they can be connected to the internet to achieve information sharing. [3] 2. Intelligence. Smart appliances can automatically respond to different environments without human intervention. For example, intelligent air conditioning can automatically adjust its working state according to different seasons, climates, and user regions to achieve the best results. 3. Openness and compatibility. Due to the possibility that users' smart home appliances may come from different manufacturers, the smart home appliance platform must have development and compatibility. 4. Energy conservation. Intelligent home appliances can automatically adjust their working hours and status based on the surrounding environment, thereby achieving energy conservation. 5. Ease of use. Due to the complex control operation process being solved by controllers embedded in smart appliances, users only need to understand very simple operations. Smart home appliances do not simply refer to a particular household appliance, but should be a technological system. With the continuous development of human application needs and home appliance intelligence, their content will become more diverse. The functions of smart home appliances may vary depending on the actual application environment, but generally should have the following basic functions: (1) communication function. Including telephone, network, remote control/alarm, etc. (2) Intelligent control of consumer electronics products. For example, a microwave oven that can automatically control heating time and temperature, an intelligent air conditioner that can automatically adjust temperature and humidity, a TV/VCR that can automatically search for TV programs and record them according to instructions, and so on. (3) Interactive intelligent control. The voice control function of smart home appliances can be achieved through speech recognition technology; By using various active sensors (such as temperature, sound, motion, etc.) to achieve proactive action response for smart home appliances. Users can also define different responses for different smart appliances in different scenarios. (4) Security control function. Including access control system, automatic fire alarm, gas leakage, electric leakage, water leakage, etc. (5) Health and medical functions. Including health equipment monitoring, remote diagnosis and treatment, elderly/patient abnormal monitoring, etc. The rapid development of intelligent control technology and information technology has also provided possibilities for the automation and intelligence of household appliances. Intelligent home appliances are home appliance devices that automatically monitor their own faults, measure, control, adjust, and communicate with remote control centers. Traditional household appliances include air conditioners, refrigerators, vacuum cleaners, rice cookers, washing machines, etc. New types of household appliances include induction cookers, disinfected cupboards, steam cookers, etc. Whether new or traditional household appliances, their overall technology is constantly improving. The key to the progress of household appliances lies in the adoption of advanced control technology, which has transformed them from mechanical appliances to intelligent devices. Intelligent household appliances reflect the latest technological advancements in household appliances
