Sterilization and refreshing control method of refrigerator

Abstract

The invention discloses a sterilization and refreshing control method of a refrigerator. The sterilization and refreshing control method comprises the following steps of: (1) detecting whether a refrigerator door is opened; (2) when the refrigerator door is closed each time, controlling the refrigerator to enter a first mode; (3) after a sterilization device and a fan continuously run a first predetermined time, controlling the refrigerator to enter a second mode, wherein the second mode comprises the steps of: (a) continuously running the sterilization device and the fan for a second predetermined time, and (b) stopping running for a third predetermined time, and circularly executing the steps (a) and (b) for the predetermined times; (4) after the steps (a) and (b) are circularly executed for the predetermined times, controlling the refrigerator to enter a third mode; and (5) returning to the step (3) and circularly executing the steps (3) and (4). According to the sterilization and refreshing control method of the refrigerator, disclosed by the embodiment of the invention, the sterilization efficiency is improved, the switch on time of an ultraviolet lamp is greatly shortened under the condition that the sterilization and refreshing effects are guaranteed, and further the service life of the ultraviolet lamp is prolonged.

Description

technical field [0001] The invention relates to the technical field of refrigerators, in particular to a method for controlling sterilization and preservation of refrigerators. Background technique [0002] The fresh-keeping and sterilization functions of existing refrigerators are generally realized by direct ultraviolet irradiation on the storage space in the refrigerator cabinet through ultraviolet lamps. In this way of direct irradiation by ultraviolet lamps, it is easy to form a dead angle that cannot be irradiated by ultraviolet lamps after storing items in the storage space, thereby reducing the sterilization effect of ultraviolet lamps. In addition, some food is usually placed in the storage space. If the ultraviolet light irradiates the food for a long time, it may destroy the nutrients of the food, such as meat, fruits, vegetables, etc., and affect the quality of the food. Moreover, the life of the current ultraviolet lamp is generally within 5000 hours, and the s...

AI Technical Summary

Problems solved by technology

This method of direct irradiation with ultraviolet lamps will easily form a dead angle that cannot be irradiated by ultraviolet lamps after storing items in the storage space, thereby reducing the sterilization effect of ultraviolet lamps

In addition, some food is usually placed in the storage space. If the ultraviolet light irradiates the food for a long time, it may damage the nutritional content of the food, such as meat, fruits, vegetables, etc., and affect the quality of the food.

Moreover, the current life of ultraviolet lamps is generally within 5,000 hours, and simple average opening and closing will greatly shorten its actual service life.
