The sterilization area is used for determining sterilization equipment needing to be started, the sterilization grade comprises sterilization intensity and sterilization termination time, and the sterilization intensity is used for determining an operation mode corresponding to the sterilization equipment needing to be started.

Further, the sterilization area of the refrigeration equipment is determined by the storage area of the stored articles, optionally, when the storage space of the stored articles in the refrigeration equipment is determined, the storage section corresponding to the storage area of the stored articles is determined as the sterilization area according to the determined storage area of the stored articles, for example, only a single storage space of the stored articles is provided in the refrigerator, the storage space of the stored articles is divided into A, B, C three specific storage sections, wherein the section B includes the section a, the section C includes the section a, and when the storage area of the stored articles is judged to be larger than the area of the section a and smaller than the area of the section B, the section B is determined as the sterilization area. Optionally, when the storage space of the stored articles in the refrigeration device is multi-level, the storage position of the stored articles is firstly positioned, that is, the storage layer where the stored articles are located is determined, and then the storage layer is determined as the sterilization area, or the sterilization area is determined according to the storage area of the stored articles. For example, when the refrigerator has three storage spaces, that is, A, B, C storage levels, in which various items can be stored, it is determined that the items are stored in the layer a among the three storage levels of the refrigerator, and the layer a is determined as the sterilization area.

Further, after the sterilization area is determined, the sterilization equipment (e.g., UVC LED sterilization lamp, ozone generator, ultraviolet sterilizer, etc.) corresponding to the sterilization area is determined to be the sterilization equipment to be activated. For example, when the refrigerator has three storage spaces, that is, the refrigerator has A, B, C three storage levels for storing various articles, level a is determined as a sterilization area, the sterilization apparatus corresponding to level a is determined as the sterilization apparatus that needs to be activated, and the sterilization apparatuses of level B and level C are determined as the sterilization apparatuses that do not need to be activated.

Namely, the second preset time is determined as the sterilization termination time, and the second preset sterilization intensity is determined as the sterilization intensity.

And when the mild sterilization grade is reached, the sterilization equipment is enabled to sterilize the stored objects within a third preset time period and with a third preset sterilization intensity.

Optionally, the higher sterilization grade of the first sterilization grade and the second sterilization grade is selected as the final sterilization grade, for example, when the first sterilization grade is determined as a light sterilization grade and the second sterilization grade is determined as a medium sterilization grade, the final sterilization grade is determined as a medium sterilization grade.

As an alternative embodiment, it is determined whether the buffering end time is less than the latest historical sterilization end time, and a third determination result is obtained.
