Home Appliances
Home appliances (household appliances) are indispensable companions in our modern life. They provide us with a stable and comfortable living environment. There are many types of home appliances, including electric water heaters, refrigerators (or freezers), air conditioners, washing machines (such as drum washing machines, straight cylinder washing machine, fully automatic washing machine, DIY washing machines), etc.
Electric Water Heater
Introduction:
The electric water heater is a device that converts electrical energy into heat energy to provide hot water. There are many types of electric water heaters, such as storage water heaters, instant water heaters, air energy water heaters and so on. Take storage water heaters as example, it is composed of water reservoirs, electric heating pipes, and control systems.
Working process:
1. Input temperature, power, time and other parameters through the panel.
2. The control system will control the electric heating pipe to heat the cold water in the water reservoir.
3. The detection system will detect in real time whether there are safety issues in the working circuit.
The role of solid state relays:
1. Control the working status of electric heating pipes and other actuators.
2. Electrically isolate the control device from the actuator.Refrigerator
Introduction:
The refrigerator (or fridge) are used to transfer heat energy inside the refrigerator to the outside, through controlling the physical state of the refrigerant. Usually the refrigerator is composed of storage box, refrigeration compressor, refrigerant, etc.
Working process:
1. Adjust the temperature and other parameters through the panel.
2. The refrigeration system works, and the refrigerant absorbs the heat in the refrigerator.
3. By the heat transfer system, the heat absorbed by the refrigerant is discharged to the outside of the refrigerator.
The role of solid state relays:
1. Control the working status of actuators such as electric compressors.
2. Electrically isolate the control device from the actuator.Air Conditioner
Introduction:
The working principle of the air conditioner is similar to that of the refrigerator, but the air conditioner is used to adjust the indoor temperature, and the cooling temperature will not be lower than 16℃. The air conditioner consists of control system, compressor, condenser, water pump, fan, etc.
Working process:
1. Adjust the temperature, wind speed and other parameters through the air conditioner remote control.
2. The refrigeration system will cool the indoor air.
3. The heat in the room will be discharged outside.
The role of solid state relays:
1. Control the working status of compressors, fans and other actuators.
2. Electrically isolate the control device from the actuator.Washing Machine
Introduction:
The washing machine is a device that converts electrical energy into mechanical energy to simulate manual washing and dehydration. The washing machines can be divided into two types: straight type and drum type. The washing machine consists of inner cylinder, outer cylinder, control system, motor, water pump and etc.
Working process:
1. Put the clothes and detergent (or washing powder) into the washing machine and set the corresponding parameters.
2. Under the action of the control system, the washing machine will wash and dehydrate the clothes.
The role of solid state relays:
1. Control the working status of motors, pumps and other actuators.
2. Electrically isolate the control device from the actuator.Recommended Solid State Relay
