Air-cooled refrigerator and sterilization control method thereof

Abstract

The invention provides an air-cooled refrigerator and a sterilization control method thereof. A sterilization device is arranged in the air-cooled refrigerator and comprises a booster circuit and an ion generator which are connected through a connecting cable, wherein the booster circuit is controlled to operate in a shutdown mode, a high-voltage mode and a low-voltage mode; and the ion generatoris used for being excited by first voltage provided by the booster circuit in the high-voltage mode to be ionized so as to release sterilization ions and heating under second voltage provided by the booster circuit in the low-voltage mode so as to eliminate condensation. The control method further comprises the steps that a starting signal for triggering the sterilization device to be started is obtained; the booster circuit is controlled to operate in the mode that the shutdown mode, the high-voltage mode and the low-voltage mode are circularly alternated, and the number of cycles is counted;a shutdown signal for triggering the sterilization device to be shut down is obtained; and the booster circuit is controlled to be shut down, and the respective duration of the booster circuit working in each mode in the cycle period is reset according to the number of cycles so as to be used when the sterilization device is started next time.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to an air-cooled refrigerator and a sterilization control method thereof. Background technique [0002] Refrigerators are a relatively common household appliance that prolongs the freshness of food by refrigerating and freezing. In order to ensure the effect of refrigeration and freezing, it is required that the refrigerator box has good sealing performance. [0003] However, if the food is stored in this sealed environment for a long time, especially for fresh vegetables placed in the cold room, the loss of water will stimulate the release of ethylene from the fruits and vegetables, promote the disintegration of chloroplasts, the tissue cell membrane will decline, and the storability and disease resistance will decrease. On the other hand, under the temperature conditions of the cold room, some bacteria can still survive and multiply, thereby posing a threat to the...

AI Technical Summary

Problems solved by technology

Bacteria can multiply in hard-to-clean places such as air ducts that cannot be seen by the user

This has seriously affected the safety of the storage environment of the refrigerator, resulting in a greatly increased rate of spoilage of stored items

[0005] Although some sterilizing devices for refrigerators have appeared in the prior art, due to the low-temperature and humid environment inside the refrigerator, the working reliability of the sterilizing devices is poor and cannot meet the requirements of users
