Description

  The present invention relates to a structure of a portion in which a connector is disposed for electrical connection with another device in a device such as a quick cooler.

The quick cooler is used to rapidly cool cooked foods to a low temperature at which bacteria do not propagate and to be used for subsequent storage. For example, during cooling, the internal temperature is maintained at a set temperature. On the other hand, the operation of the freezer is controlled, and the internal temperature (core temperature) of the food is detected, and when the detected temperature falls to the set temperature of the core temperature, the freezer is stopped (for example, patent Reference 1).
In this case, it is preferable to select the optimal temperature and set temperature for the core temperature according to the conditions such as the type and size of the food to be cooled and the amount to be cooled at one time. Therefore, there is a case where a history of the state of the cooling operation is left and compared with the cooling state of the food. Specifically, a printer is connected to the rapid cooling box, and the history is printed out by the printer.
