The food is easy to rot in hot seasons, so that the refrigerating equipment becomes an effective means for people to store the food in the hot seasons, fresh vegetables and the like are stored in a refrigerating mode, meat, wrapped dumplings and the like are stored in a refrigerating mode, but food cells change in the process of refrigerating and cooling, when the temperature of the food is reduced to minus 1 ℃ to minus 5 ℃, tissue fluid and other water in the cells can be frozen into ice crystals, the temperature zone is called as a maximum ice crystal generation zone, the generated ice crystals are different in size due to the high and low freezing speed of the food, the generated ice crystals are larger, and the larger ice crystals can puncture cell membranes. When the food is thawed, cell sap in the cell with punctured cell membrane can be lost, so that the food has reduced delicate flavour and lost nutrients. Therefore, the refrigeration equipment with the quick-freezing function is gradually popularized, and the quick-freezing can enable food to finish the freezing process at the highest speed. During the process of quick freezing food, the smallest ice crystal will be formed, and the tiny ice crystal will not pierce the cell membrane of food, so that the cell tissue fluid is completely preserved during thawing, the loss of nutrition is reduced, and the aim of preservation is achieved.

In the existing refrigeration equipment with the quick-freezing function, the quick-freezing liner usually completes foaming in the liner of the refrigeration chamber, and the quick-freezing liner is fixed with the liner of the refrigeration chamber through the adhesion of a foaming agent. The fixing mode ensures that the quick-freezing inner container is not firmly connected with the inner container of the refrigerating chamber, and further easily causes the falling of the quick-freezing inner container under the action of external force, thereby influencing the normal operation of refrigerating equipment and reducing the use experience of users.
