Description of the Related Art In a general refrigerator, a refrigerating unit of a storage includes an evaporator and a fan for the evaporator provided inside the refrigerator, a compressor provided outside the refrigerator, a condenser and a fan for the condenser. They are connected by a circulation passage. Therefore, when the compressor is driven to send the adiabatic compressed refrigerant gas to the condenser, the refrigerant gas is liquefied by the air blown from the condenser fan and sent to the evaporator.
Here, the liquefied gas of the evaporator receives air blown in the storage by the evaporator fan, evaporates and evaporates to be a gas refrigerant, and returns to the compressor. Thus, the temperature and humidity in the storage can be reduced.

なっている。[0006] As shown in FIG. 4, the control unit constantly detects the air temperature of the storage room detected by the temperature sensor, and based on the detected temperature and the set temperature set by the temperature setting device,
If detected temperature ≧ set temperature, an ON signal is output to the compressor, and if detected temperature <set temperature, an OFF signal is output to the compressor. Therefore, as shown in FIGS.
The compressor is driven for the output of the signal, and is stopped for the output of the OFF signal. After the compressor is stopped, the compressor receives the ON signal within the restart delay time Td after the compressor is stopped in order to prevent a failure due to frequent drive stop due to the output of the ON / OFF signal due to a change in the internal temperature of the compressor. , And is driven after the restart delay time Td has elapsed.

度は上昇する。On the other hand, as shown in FIG. 4C, when the set humidity set by the humidity setting device is low, the evaporator fan stops driving based on the ON / OFF signal of the compressor. When the set humidity is high, the compressor is driven regardless of the ON / OFF signal of the compressor. Accordingly, as shown in FIGS. 4D and 4E, when the evaporator fan is driven together with the compressor when the internal temperature and the internal humidity rise with respect to the set temperature and the set humidity, the internal temperature and the internal The humidity decreases, and when the evaporator fan stops together with the compressor, the internal temperature and the internal humidity increase.

庫内湿度が急激に上昇する。However, in the above-described conventional method for controlling a refrigerator, as shown in FIGS. 4D and 4E, when the set humidity set by the humidity setter is low, the fan for the evaporator is not used. When the compressor and the evaporator fan are driven, the interior of the refrigerator is dehumidified while being cooled by the evaporator, so that the humidity in the refrigerator is reduced. Further, when the compressor and the evaporator fan stop, the dew adhering to the evaporator spontaneously re-evaporates, and the humidity in the refrigerator gradually increases. On the other hand, when the set humidity set by the humidity setter is high,
When the compressor is operating, the inside of the refrigerator is dehumidified while being cooled by the evaporator as described above, and the humidity in the refrigerator decreases. However, even when the compressor is stopped, the evaporator fan is driven, and at this time, the dew adhering to the evaporator promotes re-evaporation by the blowing operation of the evaporator fan,
The humidity in the refrigerator rises sharply.

困難であった。Therefore, in the conventional method for controlling a refrigerator, when the evaporator fan is linked with the compressor, the humidity setter becomes too low relative to the set humidity. If the fan is constantly driven irrespective of the compressor, it becomes too high with respect to the humidity set by the humidity setting device. As described above, with the conventional refrigerator control method, it has been difficult to properly obtain the set humidity set by the humidity setting device.

きる。Further, according to the control method of the refrigerator of the present invention, the refrigerant gas adiabatically compressed by the compressor is liquefied in the condenser and then sent to the evaporator in the storage, and the evaporator fan A refrigerator is configured to cool the air in the storage circulating by the evaporator by the evaporator, and the compressor is stopped based on the preset set temperature and the detected temperature in the storage while the fan for the evaporator is compressed. The evaporator fan is driven together with the compressor because it is driven based on the drive signal of the compressor, and is stopped based on the stop signal of the compressor and driven again for a preset re-drive time after the elapse of the pause time. After the stoppage, the drive will be driven again for the re-drive time after the elapse of the pause time.At this time, the increase in the humidity in the refrigerator can be promoted, and the humidity in the refrigerator can be changed to an appropriate humidity to ensure the quality of the storage in the refrigerator. It may be possible to hold.
