Refrigeration equipment heat preservation box and refrigeration equipment

The invention discloses a refrigeration equipment heat preservation box and refrigeration equipment. The refrigeration equipment heat preservation box comprises a foaming box body and an outer door. The foaming box body comprises an outer shell and a liner arranged in the outer shell. A foaming cavity is formed between the outer shell and the liner which is internally provided with a partition. The partition divides the liner into a freezing cavity and a refrigeration cavity. A second foaming cavity is formed in the partition and communicates with the foaming cavity. A foaming layer of an integrated structure is formed in the second foaming cavity and the foaming cavity. The foaming box is further provided with an inner door used for opening and closing the freezing cavity. The lower end of the inner door is provided with a rotary shaft which is horizontally mounted on the liner. The front end face of the partition is further provided with a supporting component used for supporting the inner door to flat lie.
