流の場合に比較して悪く、庫内温度と一致するまでに時
間を要するためである。(B) Conventional Technology In the cooling box body cooled by the natural convection method, it was very difficult to determine the position where the temperature sensor is placed. For example, when the door was closed after the cargo handling work, it took a considerable time for the temperature display to return to the original low temperature. Despite the fact that the actual internal temperature has dropped, the heat transfer coefficient between the air and the temperature sensor body is worse in the case of natural convection than in the case of forced convection, and it does not match the internal temperature. This is because it takes time.
また、温度センサーを設置する場所についても庫内天
井部に設置した場合、天面冷却器の有無により表示温度

更に、冷気が滞留する下部に温度センサーを設置した
としても庫内に積載する商品により冷気循環が妨げられ
ば温度は高く表示することになる。Further, even if a temperature sensor is installed in the lower part where cold air stays, if the cold air circulation is hindered by the products loaded in the refrigerator, the temperature will be displayed high.

ことを目的とする。(C) Problems to be solved by the present invention The present invention has been made in view of the above-mentioned points. In a natural convection cooling type cooling box body having a cooler in the inner box, the inside temperature is accurately measured and displayed. It is an object of the present invention to provide a temperature detection device that operates.

たことを特徴とする。(D) Means for Solving the Problems The present invention relates to a cooling box body in which a foam heat insulating material is filled between a heat-conducting inner box having a cooling pipe and an outer box, and an opening is opened and closed by a door. A hollow portion is formed by the wall of the inner box and a partitioning plate having good heat conductivity embedded in the heat insulating material, and a slit hole is provided in the wall surface, and the temperature sensing portion of the temperature detector is arranged and housed in the hollow portion. A cooling pipe is provided in the vicinity of the temperature sensing part.

る。(E) Operation According to the above configuration, since the space of the hollow portion in which the temperature sensing portion is arranged and housed is limited, the temperature sensing performance of the temperature sensing portion is good. Further, although the air temperature in the refrigerator changes depending on the opening / closing of the door, the temperature of the hollow portion is not so much affected if the opening / closing time is short. Even when the door is opened for a long time, since the partition plate has good thermal conductivity, the temperature of the hollow portion drops faster than that of the inside of the refrigerator, so that the temperature sensing portion has high temperature followability. Further, by providing the temperature sensing portion in the vicinity of the cooling pipe, the temperature change is always received prior to the air inside the refrigerator, and the temperature display by the temperature sensor approaches the true value of the inside temperature.
