Washing machine control unit
Washing machine control unit can be divided into complete circuit, system circuit and unit circuit.
1. Complete circuit
The so-called complete circuit is to connect the various parts of the entire computer board to each other, all reflected on a piece of paper, there is a holistic and comprehensive feeling, so that people have a comprehensive understanding of the structure of the entire circuit after reading. Of course, to understand such drawings requires maintenance personnel to have a certain basic knowledge of the circuit and reading ability.
2. System circuit
The system circuit is to divide the whole machine circuit into several large blocks. For example, the whole machine circuit can be divided into power circuit, synchronous control circuit, microprocessor circuit, protection circuit, power supply circuit, system control circuit, etc. according to the structure of the computer board. More detailed and clearer than the whole circuit.
3. Unit circuit
The unit circuit is a thinner and smaller block circuit divided by the system circuit, which makes the drawing look simpler and clearer, which is convenient for maintenance and use.
