DEVICE FOR CONTROLLING VACUUM OF EACH DIVISION OF VACUUM REFRIGERATOR

摘要

PURPOSE: A device for controlling vacuum of each division of vacuum refrigerator is provided to prevent oxidation of food by keeping a food storage compartment vacuous and to keep each of divisions of the food storage compartment vacuous in order. CONSTITUTION: A vacuum refrigerator includes a vacuum chamber(30) and a vacuum control device. The vacuum chamber is placed on a cold air passage and is divided into a plurality of spaces(30a,30b,30c,30d,30e) by partitions(31). The vacuum control device discharges air in the spaces in order to keep vacuum. The vacuum control device includes a vacuum pump(40); a pressure control part(50); and valves(60). The vacuum pump is placed to be fluidically connected with one of the spaces to discharge air. The pressure control part is placed in one of the spaced most distant from the space where the vacuum pump is placed to turn on/off the vacuum pump according to pressure. The valves are placed on the partitions to open and close in order according to differences of pressure of the spaces.
