摘要： A refrigerator (10) includes a vacuum cabinet (20) which includes a vacuum compartment (42) and an open top drawer (34) in the vacuum compartment. When the refrigerator door is closed, a rotary spool (75) of the air control valve (70) is moved to a position to recirculate air from the vacuum compartment through the vacuum pump (65) back into the vacuum compartment so as to pre-chill the contents of the vacuum compartment. Later, while the refrigerator door is still closed, the air control valve is shifted so that the vacuum pump (65) draws air from the vacuum compartment until a predetermined low air pressure is detected in the vacuum compartment, whereupon the operation of the vacuum pump terminates. When the refrigerator door is opened, the valve spool (75) rotates to vent the vacuum compartment to the atmosphere, thereby equalizing the pressure within the vacuum compartment to atmospheric pressure and allowing the open top drawer of the vacuum compartment to be opened.
