２が何らかの原因で故障した場合温度制御が不能
となる欠点を有していた。 Generally, the temperature control of storage is as shown in Figure 1.
The temperature inside the storage is detected by a temperature detector 1, the control device 2 displays the detected temperature on a display device 3, and further controls the cooling or heating device 4 when the temperature inside the storage reaches a predetermined temperature. At the same time, the alarm device 5 issues an alarm. However, this method has the disadvantage that temperature control becomes impossible if the temperature sensor 1 or the control device 2 breaks down for some reason.
本発明は上述した欠点に鑑みて為されたもので
あり、従来の欠点を完全に除去した保存庫の温度
制御装置を提供するものである。 The present invention has been made in view of the above-mentioned drawbacks, and it is an object of the present invention to provide a storage temperature control device that completely eliminates the conventional drawbacks.

を示す。 The present invention will be described in detail below with reference to the drawings. In FIG. 2, 6 and 7 are first and second temperature detectors installed in the storage, respectively, and 8 and 9 are first and second temperature detectors, respectively. First and second control devices to which the outputs of the detectors 6 and 7 are applied; 10 is a temperature display device; 11 is a cooling device; 12 is an alarm device; and 13 is an alarm recording device. The case of storage is shown.

依つて庫内の温度を制御するものである。 The first control device 8 displays the temperature inside the refrigerator detected by the first temperature detector 6 digitally or analogously on the display device 10, and operates the cooling device 11 when the temperature falls outside the set temperature. Furthermore, the temperature inside the refrigerator is controlled by issuing an alarm using the alarm device 12.

ものである。 The most characteristic feature of the present invention is that the second temperature sensor 7 and the second control device 9 are
The temperature sensor 6 and the first control device 8 are provided separately. For example, when preserving blood, the storage temperature is specified in the range of 4°C to 6°C in Japan, but when referring to regulations in other countries, the minimum temperature is 3°C and the maximum is 7°C. Therefore, the control temperature range of the second control device 9 is fixed at 3° C. to 7° C.
The control temperature range of the control device 8 can be arbitrarily set within the range of 3°C to 7°C, for example, 4°C to 6°C.
℃, the first control device 8 normally controls the cooling device 11 and alarm device 16 to maintain the temperature inside the refrigerator within the set temperature range of 4℃ to 6℃. Therefore, when the temperature inside the refrigerator falls outside the international range of 3°C to 7°C, the cooling device 11 is controlled by the functions of the second temperature detector 7 and the second control device 9, and the alarm device is activated. While the alarm is issued by the alarm 12, the time during which the alarm is issued is recorded by the alarm recording device 13. Therefore, even if there is an abnormality in the first temperature sensor 6 or the first control device 8, it can be determined whether or not the blood in the chamber can be used by examining the time period during which the alarm was issued. It is.
尚、上述の例においては、第１の制御装置８の

てもよい。 In the above example, the set temperature of the first control device 8 has a range of 4°C to 6°C, that is, 5°C ± 1°C, but it is set to 5°C without a range. Good too.
上述の如く本発明に依れば血液等の重要なもの
の保存庫の温度制御系統を２系統設けることに依

適なものである。 As described above, according to the present invention, temperature control is ensured by providing two temperature control systems for the storage of important substances such as blood, which is optimal as a secondary safety measure.
