Common cold storage devices include refrigerators, freezers, and the like. The food materials placed in the refrigeration equipment are kept in a low-temperature state, so that the food materials are kept fresh.
The temperature of the traditional refrigeration equipment needs to be manually set by a user, and the temperature cannot be automatically set according to the condition of food materials stored in the refrigeration equipment. With the gradual development of the refrigeration equipment towards intellectualization, some intelligent refrigeration equipment capable of automatically setting temperature are appeared at present.
