Next, the operation will be described. Now, it is assumed that the storage battery 16 is not charged, and in that state, the outlet 22 of the cold storage 1 is connected to the commercial AC power supply in the delivery base. At this time, the LBO terminal of the booster circuit 21 is at the “L” potential, so the voltage monitoring circuit 27 triggers the gate of the solid-state relay 23 to make it conductive. As a result, AC power is supplied to the rectifier circuit 24, so the rectifier circuit 24 rectifies this AC voltage and outputs a DC voltage, which is applied to the terminal 17 of the storage battery 16 via the resistor 26. As a result, the charging of the storage battery 16 is started and the DC voltage is also supplied to the booster circuit 21. The booster circuit 21 boosts the voltage at the terminal 17 to, for example, about 12 V and applies it to the blower 13. Therefore, the blower 1

Further, in the embodiment, the low temperature cabinet 1 provided with the storage battery 16 is taken as an example, but the storage battery 16 and the rectifier circuit 2 are used.
It is also possible to eliminate 4 and the like and directly operate the blower 13 only with the electric power generated by the solar cell 15. In that case, the cold air is circulated in the storage room 6 only during the time when sunlight is shining, but since the storage battery 16 can be removed, the weight of the cold storage 1 can be remarkably reduced, and Since the application of the AC power supply can be eliminated, the standby time required for charging can be eliminated and energy can be saved. In particular, since the electric power generated by the solar cell 15 is maximized when direct sunlight is exposed during the day when the load on the cold storage 1 is the largest, the blower 13 is reliably operated at such a heavy load, and the storage room 6 The inside can be cooled smoothly and uniformly.

As described in detail above, according to the invention of claim 1, since the blower is driven by using the electric power output from the solar cell provided on the outer surface of the heat insulating box, the storage battery can be eliminated. Therefore, it is possible to improve the usability by reducing the weight of the cold storage and eliminating the waiting time required for charging, and also contributing to energy saving. In particular, during the time of direct sunlight during the day when the load of the cold storage is the largest, the electric power output from the solar cells is maximized and the cool air is circulated in the storage room, so the storage room is cooled smoothly and uniformly. It is possible to do.

Further, according to the invention of claim 2, since the output of the solar cell provided on the outer surface of the heat insulation box is connected to the storage battery, the discharge time of the storage battery can be extended, and the capacity of the storage battery can be extended. It is possible to eliminate the increase in weight of the cold storage due to expansion and improve usability, while extending the operating time of the blower and saving energy. Especially during the time of direct sunlight during the day when the load on the cold storage is the largest,
Since the electric power output from the solar cell is maximized, the storage chamber can be cooled smoothly and uniformly.
