Document Type and Number:
Japanese Patent JP7032026
Kind Code:
B2
Abstract:
To suppress liquid return caused by a door being opened/closed at a short interval.SOLUTION: In a refrigerator 1, a microcomputer 31A performs fan control processing so that rotational frequency per unit time of an internal fan 27 is lowered to second rotational frequency or less that is lower than first rotational frequency to be rotational frequency of the internal fan 27 when a heat insulation door 12 is closed in the case that it is detected by a human detection sensor 32 that the heat insulation door 12 is opened, and the internal fan 27 is rotated with the first rotational frequency when a prescribed condition is satisfied later on, and does not perform the fan control processing in the case that it is detected by the human detection sensor 32 that the heat insulation door 12 is opened before time T1 passes after the rotational frequency of the internal fan 27 is lowered by the fan control processing to the second rotational frequency or less, but rotates the internal fan 27 with rotational frequency higher than the second rotational frequency.SELECTED DRAWING: Figure 6
