Description

Technical Field

[0001] The present invention relates to the technical field of air water production equipment, and particularly to a circulating sterilization water treatment device and a circulating sterilization method for an air water maker. Background Art

[0002] In the related technologies of air water production, in order to produce clean potable water, an ultraviolet sterilization device is usually set in the water production process. This device can effectively kill microorganisms such as bacteria and viruses in water, ensuring the safety of water quality. Subsequently, the water treated by sterilization will be heated by a heating device or cooled by a refrigeration device to meet the different needs of users for hot water or cold water, providing a comfortable and safe drinking water experience.

[0003] However, there is a drawback in this traditional device and water treatment method. When the device has not been used to draw water for a long time, the water remaining in the water heating, water cooling and other devices downstream of the ultraviolet sterilization device and the water in the pipelines connecting these devices is prone to gradual deterioration of water quality due to the lack of necessary circulation and renewal. This is mainly because water is more likely to breed microorganisms such as bacteria and molds in a static state, and at the same time, chemical substances in the water may change due to factors such as light and temperature, such as the generation of peculiar smells, abnormal colors or an increase in harmful substances. The water quality will not only affect the taste and safety of subsequent drinking, but also pose a potential threat to the health of users. Summary of the Invention
