Abstract
A control method of a refrigerating and freezing device and a refrigerating and freezing device are provided. The refrigerating and freezing device includes a cabinet defining a storage compartment. The control method includes a refrigerating operation step, a foodstuff determining step, and a cooling operation step. The refrigerating operation step is to control a temperature of the storage compartment to be within a first preset temperature range. The foodstuff determining step is to determine whether a new foodstuff is put into the storage compartment. The cooling operation step is to, when a new foodstuff is put into the storage compartment, cool the storage compartment. Since the temperature of the new foodstuff is greater than that of the original foodstuffs in the refrigerating and freezing device, cooling the storage compartment changes a storage temperature suitable for the foodstuffs originally stored in the storage compartment into a storage temperature suitable for the foodstuffs originally stored in the storage compartment into a storage temperature suitable for the new foodstuff, and the storage temperature is more convenient for the preservation of the new foodstuff and ensures good storage conditions for the newly put foodstuff. Furthermore, the preservation effect on the original foodstuffs will not be affected, and the preservation effect of the refrigerating and freezing device on the foodstuff is enhanced.
