At present, the development of my country's small home appliance control panel industry is uneven, and the prices of products in the market are also very different. Home appliance control panels are the core of home appliance quality. Many control panel manufacturers do not provide corresponding solutions. What are the common small home appliance control panels? Woolen cloth?

　　Common home small appliance control panel solutions:

　　1. In order to prevent the conduction interference generated by the control panel circuit of small household appliances, a capacitor C can be connected in parallel at the inlet of the circuit, a simple connection diagram of the capacitive anti-interference circuit. The capacitor is a safety capacitor, but a safety resistor must be connected in parallel at both ends of the capacitor to prevent the power cord plug from being charged for a long time when the power cord is unplugged and inserted.

　　2. The capacity of small home appliance control panel capacitors should not be too large, and the filtering performance of large-capacity capacitors for filtering high-end interference signals is extremely poor, especially the high-frequency performance of polyester film capacitors is generally poor, and polyester The high frequency response characteristics of thin film dielectrics are far from ceramic or mica.

　　3. The non-linear load of the control panel of small home appliances is a source of interference with extremely wide frequency, especially the interference of the non-linear load. There are two main methods to suppress it. One is to start with the non-linear load itself. In order to reduce the interference, the carbon brush itself should be guaranteed. The quality of the commutator and the smoothness of the commutator should also be protected. At the same time, the carbon brush should be protected to have proper pressure on the commutator. Finally, the fixing of the machine base should be reliable to avoid unstable operation caused by mechanical operation.
