Electric control board integrated with power supply, display, control and illumination and refrigerator

Abstract

The invention relates to an electric control board integrated with power supply, display, control and illumination. The electric control board comprises an MCU, a key control module, a display control module, a power supply control module and an illumination control module. The power supply control module supplies power to the MCU, the key control module, the display control module and the illumination control module respectively. The key control module is used for receiving an external input signal and feeding back the external input signal to the MCU. The display control module is used for receiving a display control signal of the MCU and displaying an output signal. The illumination control module is used for receiving an illumination control signal of the MCU and controlling the illumination inside a refrigerator. The power supply part, MCU control, the display control part and illumination control are all integrated on one electric control board, so that multiple wiring harness connections are reduced, structure verification and conflict are reduced, subsequent production and equipment are optimized, production efficiency is greatly improved, and the cost problem is also solved.

Description

technical field [0001] The invention relates to the field of refrigerator control, in particular to an electric control board and a refrigerator integrating power supply, display, control and lighting. Background technique [0002] At present, the control system of most electronically controlled refrigerators is usually composed of the main control board and the display control board. Generally speaking, the interior of the refrigerator needs lighting, and most of the existing lighting lamps are LED lights. The main control board mainly provides power and logic control for the entire control system, and the display control board is used for operation and control, as well as display. First of all, the main control board, display control board and LED light board need a certain structure to install and support, and there are connecting harnesses inside the refrigerator to connect these control modules, which requires a complex and rigorous design, and analysis Quite a lot of ...
