Despite the ventilation, there were problems such as mold generation on the stored grains. For this reason, weather conditions are constantly monitored, and the ON / O of the ventilation system is adjusted accordingly.
The FF operation had to be performed manually. In addition, in the case of a storage using a humidity control agent, maintenance such as regeneration or replacement of the humidity control agent containing moisture, for example, in the case of silica gel, regeneration by sun drying or the like is indispensable.

When the power switch 8 is turned on, first, S
At 1, the outside air humidity HU1 is detected by a humidity sensor 7 arranged outside the exhaust port 5. Next, in step S2, the fan 6 is driven to discharge the air inside the storage from the exhaust port 5 to the outside, and the timer 11 is started. Subsequently, the humidity HU2 of the inside air passing through the exhaust port 5 is detected by the humidity sensor 7 (S3). The outside air humidity HU1 and the inside humidity HU2 detected in S1 and S3 are compared with a predetermined set humidity HU0, and the outside air humidity HU1 is equal to or less than the set humidity HU0, and
When the humidity HU2 in the refrigerator is equal to or higher than the set humidity HU0, it is determined that the humidity in the refrigerator is too high, and the fan 6 is continuously driven to ventilate the refrigerator. The inside humidity is reduced appropriately by taking in outside air having a lower humidity than the inside humidity. Subsequently, in S5, the ventilation of the entire inside of the refrigerator is performed, and when at least a predetermined period of time sufficient for exhausting the high-humidity indoor air to the outside elapses, a signal is output from the timer 11 and the fan 6 is output. Is stopped (S6).

In S4, if HU1≤HU0≤HU2 is false, it is determined whether the humidity in the refrigerator is maintained at an appropriate level.
Since the outside air is considered to be highly humid, it is determined that ventilation is unnecessary, and the fan 6 is immediately stopped (S7). Accordingly, it is possible to prevent energy consumption by useless fan driving and prevent the inside of the compartment from becoming humid due to the outside air having a higher humidity than the inside humidity HU2 flowing into the compartment. In S8, a series of operations is ended when a certain time has elapsed.

The above operation is repeated at regular intervals, and the fan 6 is driven as necessary to ventilate the interior of the refrigerator. In general,
Humidity suitable for storing rice is said to be 70-80%.
Therefore, for example, a humidity of 60% is set as the set humidity HU0. By setting the set humidity HU0 lower than the optimal humidity for storing rice, ventilation can be started before the humidity in the refrigerator becomes too high. Further, since the ventilation is not performed when the inside humidity HU2 is smaller than the set humidity HU0, the inside humidity does not become lower than the set humidity HU0 (for example, 60%) due to the ventilation by the fan 6, and is stored. No grain is exposed to overdrying.

Further, in the above embodiment, the humidity detecting means is provided outside the exhaust port, detects the outside air humidity when the ventilator is stopped, and detects the inside humidity during operation, but this is not restrictive. For example, the humidity detecting means may be arranged inside the air inlet, to detect the humidity in the refrigerator when the ventilation device is stopped, and to detect the humidity of the outside air introduced from the air inlet during operation.

Next, another embodiment of the present invention will be described. The humidity detecting means is provided in the exhaust hole of the ventilation port, and a ventilation device is provided for the ventilation port. This ventilator can perform both an exhaust operation and an intake operation, and the air and outside air in the compartment flow through the exhaust holes depending on the operation direction of the ventilator. Therefore, the inside humidity and the outside air humidity can be detected by one humidity detecting means provided in the exhaust hole.

As described above, according to the present invention, the outside air and the humidity inside the storage are detected by the humidity sensor, and the ventilation device is controlled based on the detected humidity. Monitoring of the weather conditions that had to be done and the need to manually turn on / off the ventilator can be saved. In addition, since the humidity sensor is mounted near the ventilation port, both the outside air and the inside air can be controlled by one humidity sensor when the ventilation device is stopped and when the ventilation device is operated, or when the exhaust operation and the intake operation are performed. It is very efficient because it can detect humidity. In addition, ventilation is performed when the detected outside air humidity is lower than the set humidity, so high humidity outside air is taken in or even though the humidity in the refrigerator is kept at the optimum humidity for grain storage There is no need to run the ventilation system,
Operation costs can be reduced.
