おこしてしまう。Problems to be Solved by the Invention However, with the above-described configuration, it was not possible to tell when the cold storage type heat exchanger had completed its cold storage. For this reason, it is possible that the person in charge of transportation may load the transported items into a cool storage type refrigerator that has not yet completed cold storage, and in this case, sufficient cooling capacity may not be obtained and the temperature inside the refrigerator will rise by the time it arrives. This poses a problem in that the quality of important transported goods deteriorates. In addition, when cooling the cold storage room, the person in charge of transportation must turn on the changeover switch, so if the person in charge of transportation forgets to turn on the changeover switch, the temperature of the cold storage room will drop to the set temperature when the cold storage type refrigerator is needed. This means that it cannot be used. Furthermore, if the person in charge of transportation leaves the changeover switch OFF/OFF for a long time after transportation, the blower will continue to operate and the storage battery will be completely discharged, causing deterioration of the storage battery performance.

ることができる。The power input determining means 48 detects this, and the compressor operating means 44 operates the compressor 34 to perform cold storage operation. The cold storage agent 28 is then cooled by the cooled cooler 29. As the temperature of the cold storage agent 28 decreases, the temperature of the cold storage agent 28 decreases.
The temperature of the temperature detection section 38 also decreases. When the cooling further progresses and the temperature reaches T1 at time t1, it becomes lower than the set temperature of the temperature determining means 42, and a signal is sent. When the compressor control means 44 receives the signal, the compressor 34 is stopped and the cooling operation is stopped. After cooling operation is stopped, temperature detection section 3
When the temperature of the compressor 8 rises and exceeds T2 (T2 - T1 is a differential) at time t2, the compressor 34 operates again and performs cooling operation. In this way, the compressor 34
By repeating N10 F F, the cool storage agent 28 is kept at a constant temperature. Also, during this cold storage operation, the rechargeable storage battery 46
is charged by the charger 45. When the rechargeable storage battery 46 is almost fully charged, a signal is sent from the charging end detection means 48. When the signals from the temperature determining means 42 and the charging end detecting means 48 are both generated at time t1, the cold storage completion determining means 49 determines that the cold storage operation has ended,
At the same time, a signal is sent to the ventilation fan control means 47, and the ventilation fan control means 47 turns off the ventilation fan 30 at T3 (time tl). , ON at T4 (time t4)! t-controlled cold storage room 33
is controlled to an arbitrary set temperature, and the cold preservation display means 51 notifies the user that the temperature is being kept cold. Then, the person in charge of transport puts the goods 89 into the cold storage room 38, and at time t5, disconnects the power cord 40 from the power supply, places the goods on a transport truck, etc., and transports the goods to the destination. At this time, inside the cold storage main body 23, the latent heat of fusion of the cold storage agent 28 and the ventilation fan control means 47
The temperature of the transported goods 39 can be prevented from increasing.

Cold storage room 3 is controlled by
3 to a desired set temperature. Furthermore, even if the person in charge of transportation wants to cancel the cold storage operation, he or she presses the cold storage switch 52 again at time t8 to stop the cold storage operation, thereby canceling the temperature control of the cold storage chamber 83. If the user wants to keep the cold cold again, the cold keep switch 52 is pressed again at time t9.

の性能劣下がなく長時間使用可能となる。As described above, according to this embodiment, the power input determining means detects that the commercial power input is ONL, the cold storage agent is stored in the cooler, and the cold storage completion determining means automatically detects that the cold storage is complete. There is a freezing mode function that operates the ventilation fan to control the temperature of the cold storage chamber to a desired set temperature, and a freezing mode function that operates the ventilation fan to control the temperature of the cold storage chamber to a desired temperature setting even when the cold storage agent is storing cold by pressing the cold storage switch. There is a cold storage mode function that stops cold storage by pressing the cold storage switch again during cold storage, and when the commercial power input is OFF, the ventilation fan is operated and the cold storage room is controlled to the desired set temperature. Equipped with a rechargeable storage battery over-discharge prevention mode function that turns off the load on the storage battery, and when the cold storage agent completes cold storage, the temperature in the cold storage room is automatically controlled to the desired set temperature, so the person in charge of transportation can turn on the power. You can use the cold storage type refrigerator just by operating it. For example, if you want to use the cold storage type refrigerator immediately after turning on the power, you can press the cold storage switch after turning on the power, and it will be ready for use in a short time. Furthermore, since the load on the rechargeable storage battery is automatically turned off after an arbitrary period of time when the power is disconnected, the rechargeable storage battery can be used for a long time without degrading its performance due to human error.
