れる。After the normal operation control of the compressor (7) and fan motor (8) from step (26) to step (29) is performed, the process proceeds to step (35), and if the current state is currently defrosting or rapidly chilled. It is determined whether one of the states exists, and if it is neither, the process proceeds to step (37), and if it is either, the flag F set for prohibiting the electric damper operation is set to 0, and the electric damper operation prohibition flag is set to 0. Timer A for timing
Reset to 0. Flag F is set to 1 in step (37)
Since the flag F is O before the abnormality is detected, the process proceeds to step (30). In step (30), it is determined whether to open or close the electric damper (9), and if it is determined that the electric damper (9) should be opened, step (30)
The process proceeds to step 1), and if it is determined that the electric damper (9) should be closed, the process proceeds to step (32). These steps (31
) and (32), the current state of the electric damper (9) is determined, and if it is determined that the electric damper (9) should be opened, or if it is determined that the electric damper (9) is to be closed and the current state is When the electric damper (9) is in the closed state, step (33) or step (34) is performed as before.
) to control the opening and closing of the electric damper (9). but,
If it is determined in step (30) that the electric damper (9) should be opened, and if it is determined in step (31) that the current state of the electric damper (9) is open, the process proceeds to step (38) and the electric damper (9) is opened. 1 is added to the timer B for measuring the opening time, and in step (39) it is determined whether or not the timer B has measured time for a predetermined time Yhr', for example, 2 hours or more, and if it is less than 2 hours, the process proceeds to step (33). The electric damper (9) is left open and stopped, and the process returns to the original subroutine. After that, the above operation is repeated as long as the command to open the electric damper (9) continues, and timer B continues to measure time for a predetermined time Yh.
When reaching r, the process proceeds from step (39) to step (40), where flag F is set to 1 and timer B is reset to 0. Above steps (38) (39) and (4)
0), the electric damper opening operation time measuring means (41) is configured.

なることはない。When the flag F is set to 1, in the next cycle, the process advances from step (37) to step (42), where 1 is added to the timer A for measuring the electric damper operation prohibition time, and in step (43) this time is added. It is determined whether the timer A has measured a predetermined time Xhr, for example, 10 minutes or more. If it is within 10 minutes, the process proceeds to step (32), and since the electric damper (9) is open, the process proceeds to step (34), where the electric damper (9) is opened. is closed and timer B is reset to 0 in step (46). The above operation is repeated until the timer A reaches Xhr, but from the next cycle, the electric damper (9)
is closed, the process proceeds from step (32) to step (33) and the electric damper (9) is kept closed. That is, during this period, even if a command to open the electric damper is issued, the electric damper will not be closed.

。In this way, the electric damper (9) operates for a predetermined time Yhr,
For example, if the opening operation continues for two hours or more, the closing operation is forcibly continued for a predetermined time Xhr, for example, 10 minutes. However, if the system is currently defrosting or rapidly chilling, the process goes from step (35) to step (36) and resets the flag F and timer A every cycle, so the electric damper (9) There is no forced closing operation.

As a result, overcooling in the refrigerator compartment can be effectively prevented, and even if hot foods are placed near the internal temperature sensor, other foods will not freeze.This can be done by simply changing the program. The effect can be obtained at low cost without adding sensors or changing other hardware.
