ABSTRACT:
When a door of a refrigerator door is closed, there is provided a passage which remains open to communicate the interior of the refrigerator with air outside of the refrigerator for a predetermined time period in order to enable pressures inside and outside of the refrigerator to be equalized. Thus, the door can be subsequently opened more easily. Energy for closing the passage after the predetermined time period is stored by an energy storing member in response to either a door-opening movement or a door-closing movement.
