2. Description of the Related Art As shown in Japanese Patent Application Laid-Open No. 6-88666, an auxiliary cooling means performs back-up when a cooling failure occurs due to a power failure, an abnormality, or the like. At the same time, in order to resolve the situation quickly, an automatic warning is issued to a surveillance company in a remote area.

[0004]

However, at the time of abnormality,
An alarm was given to the surroundings because the power was supplied to the alarm circuit, but no alarm was given to the vicinity because the power supply was stopped during a power failure. For this reason,
People near the cool box may not be aware of it and be too late.

[0005] In particular, when the stored items in the cool box are precious stored items such as blood and medical drugs, even a slight increase in the temperature in the refrigerator causes a serious deterioration in quality or deterioration such as decay. Had to get rid of the situation quickly and quickly.

An object of the present invention is to provide a cool box which solves such problems (problems).

Further, conventionally, during a process for collecting a situation during a power outage, and at the time of normal recovery, since the temperature of the stored items in the cool box is not known, the stored items have to be discarded. Even though it was too late, there was a case where the process for collecting the situation was performed with full power.

Another object of the present invention is to provide a cool box which solves such problems (problems).

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described in detail with reference to FIGS.

FIG. 1 is a diagram of an ultra-low temperature cold storage, and FIG.
FIG. 3 is a diagram of an operation panel of the cool box. FIG. 3 is a diagram for explaining the operation.

In FIG. 1, reference numeral 1 denotes a cool box having an ultra-low temperature freezing room at about -80.degree. C. to -130.degree. 2 is inside the refrigerator. Reference numeral 3 denotes an operation panel for displaying the inside temperature and setting and inputting the inside temperature. Reference numeral 4 denotes a control board unit that includes a CPU and a backup battery (auxiliary power supply unit) and controls the entire cool box. Reference numeral 5 denotes an inside temperature detection sensor for detecting the inside temperature. Although the operation panel 3 and the control board section 4 are shown separately from the cool box 1 for easy understanding, they are actually built in.

In FIG. 2, reference numeral 6 denotes a temperature display section. 7
Is an alarm lamp. 8 is an alarm buzzer. Reference numeral 10 denotes a switch for indicating a temperature in the refrigerator.

The operation of the cool box at the time of a power failure will be described.

When a power failure occurs, the control board unit 4 is driven by a built-in battery. In addition, the battery drives the inside temperature detection sensor 5, the alarm lamp 7, and the buzzer 8 as well.

When the alarm lamp 7 and the alarm buzzer 8 are driven, a power failure or the like is notified around the cool box.
The surrounding people can quickly respond to the power outage, and can suppress the deterioration of the quality of precious preserved materials.

If the operator wants to check the internal temperature during this power failure countermeasure, the internal temperature display instruction switch 9 is used.
push. As a result, a control signal is output, the temperature display unit 6 is driven, and the internal temperature detected by the sensor 4 is displayed on the temperature display unit 6. As a result, the worker can grasp the current situation and take an optimal response.

FIG. 3 is a flowchart showing the operation during a power failure. In addition, in the said embodiment, although the normal time of the display part 6 was not demonstrated, this usually displays the inside temperature at all times. In other words, the inside temperature is always displayed and operates as the inside temperature notifying means. The light is turned off at the time of power failure, but the inside temperature is displayed by operating the inside temperature display instruction switch 9. The display of the inside temperature is performed when the inside temperature display instruction switch 9 is pressed, and the display may be turned off when the inside temperature display instruction switch 9 is pressed again.
From the viewpoint of energy saving at the time of power failure, the display of the internal temperature is displayed only for a certain period from the operation of the internal temperature display instruction switch 9 or only while the internal temperature display instruction switch 9 is being pressed. It is good to let.

In the above embodiment, the auxiliary cooling means at the time of a power failure is not described, but may be provided.
