POWER SUPPLY SYSTEM FOR REFRIGERATOR CONTROL APPARATUS

摘要

PURPOSE: A power supply system for refrigerator control apparatus is provided to increase operating reliability by allowing each of control devices to be independently connected to the power supply system. CONSTITUTION: A power supply system comprises an external power source for supplying power; a control unit having control devices for controlling operation of refrigerator; and a power supply unit(450) connected to the external power source and connected in parallel to control devices of the control unit, and which distributes the power supplied from the external power source to each control device. The control unit includes a data processing section(410); a driver circuit section(220) connected to the data processing section, and which transmits the signal output from the data processing section to a display unit; a modem(420) and a television tuner(415) connected to the data processing section; and an operation control section(430) for controlling cooling cycle operation of refrigerator. The data processing section, driver circuit section and operation control section of the control unit are connected in parallel to the power supply unit, and receive power independently from each other.
