The invention discloses a computer program-controller of a washing machine, which is used for being matched with a washing machine control disc seat to control the washing machine. The invention comprises a casing of the computer program-controller, a PCB board which is positioned inside the casing of the computer program-controller, a sealant which is positioned inside the casing of the computer program-controller to seal the PCB board. The PCB board comprises a strong electric board and a weak electric board, wherein, the weak electric board is provided with a CPU which controls the strong electric board through a communication wire which is connected with the strong electric board and the weak electric board. The invention provides a computer program-controller for washing machine to solve technical problems that strong electricity and weak electricity of the computer program-controller interfere each other in the prior art, and fulfills standardized demands for designing the computer program-controller.
Description
technical field [0001] The invention relates to a computer program controller for a washing machine. Background technique [0002] The existing washing machine is installed with a computer program controller and a washing machine control panel seat, and the computer program controller is responsible for controlling the specific operation of the washing machine. The existing computer program controller for a washing machine comprises a computer program controller housing, a printed circuit board (PCB board) located inside the computer program controller housing, and a sealant located inside the computer program controller housing to seal the printed circuit board. The control components on the PCB are divided into strong current components and weak current components. Strong electric components include transformers, thyristors, relays, etc. Weak current components include buttons, light-emitting diodes, LCD screens, etc. Since the strong current part and the weak current p...
