When the door of the freezer is opened and then closed, the relatively high-temperature and high-humidity outside air flowing into the freezer during the opening of the door rapidly contracts, so that the internal pressure of the freezer temporarily decreases remarkably. Then, the pressure gradually increased due to the inflow of outside air from the surroundings of the door or the gap around the heat insulating box, and the pressure was substantially balanced with the outside air pressure.

That is, in a freezer in which the inside of the refrigerator is cooled to a freezing temperature, the opening and closing of the door causes the cold air and the outside air in the refrigerator to be replaced, and after the door is closed again, the replaced outside air is cooled. As a result, the volume shrinks, and a negative pressure is significantly applied to the inside of the refrigerator. Therefore, in a situation where the door is opened again immediately after the door is closed, the force required to open the door also becomes large.

Next, a case where the door 6 is once opened and then closed again will be described. The air pressure in the compartment 3 (hereinafter referred to as the compartment pressure) is once increased by the closing pressure of the door 6 when the door is once opened and then closed again.
Thereafter, the pressure rapidly decreases due to the contraction of the outside air flowing in during opening. Then, when the internal pressure is lower than the external air pressure, the external air pressure pushes and opens the valve body 30B of the on-off valve 30 of the external air introduction unit 28 due to a difference between the internal pressure and the external air pressure,
Outside air flows into the outside air introduction unit 28.
