Abstract

The invention discloses a sterilization method of a storage chamber and a refrigerator. The storage chamber comprises a plasma generator, when it is detected that the duration of refrigeration starting of the storage chamber reaches the preset sterilization duration t', the plasma generator is started for the first time, and when the duration of starting of the plasma generator for the first timereaches first preset value T1, a fresh-keeping procedure is executed; if it is detected that the storage chamber is opened in execution of the fresh-keeping procedure, when it is monitored that the continuous opening time of the storage chamber is shorter than the preset opening duration, the plasma generator is started for a certain duration after the storage chamber is closed, then pausing is conducted, and when the pausing duration reaches a preset value, the fresh-keeping procedure continues to be executed; and the fresh-keeping procedure comprises the step of alternately executing pausingand starting of the plasma generator. Compared with the prior art, the method has the advantages that ozone concentration in the storage chamber can be controlled within a certain range while the storage effect of the storage chamber is guaranteed.

Description

technical field [0001] The invention relates to the technical field of food refrigeration, in particular to a storage room sterilization method and a refrigerator. Background technique [0002] At present, domestic refrigerators mainly rely on low temperature to keep food fresh, but low temperature can only reduce the reproduction speed of microorganisms, and cannot solve food corruption and food safety problems caused by microbial contamination during food storage. At the same time, studies have found that with the prolongation of food storage time, harmful bacteria such as Escherichia coli, Staphylococcus aureus, Salmonella, and mold will multiply on the surface of food, and fruits and vegetables will produce trimethylamine and methyl mercaptan due to corruption during storage. substance. At present, the sterilization technology of refrigerators on the market mainly includes contact sterilization methods such as antibacterial substance filtration sterilization and photoca...
