Description

Water dispenser

Technical Field

The invention relates to the technical field of household appliances, in particular to a water dispenser.

Background

At present, most of water dispensers in the market are usually provided with a water source tank for storing barreled water after a barrel neck of the barreled water is reversed, and then water is led into two water containers by a hose in the water dispenser, wherein one water container is a hot water container and the other water container is a cold water container, and the two water containers can play a role in precipitating impurities in water besides the function of discharging cold and hot water. The barreled water is usually repeatedly replaced by people, but a certain amount of water is neglected to be stored in the inner container of the water dispenser, pathogenic bacteria can be hidden in the water, and a temperature bed for bacteria breeding is naturally formed in the water. The water dispenser in the wrong region is a water purifying device for consumers, and barreled mineral water is clean, so that the water dispenser is not problematic even if the water dispenser is cleaned and disinfected irregularly, and various foreign matters can appear in the water. Therefore, the water dispenser must be thoroughly cleaned and disinfected at regular intervals.

At present, the water dispenser with the cleaning function mostly adopts ozone sterilization and sterilization by adding cleaning solvent. The ozone sterilization is adopted, residual water in the pipeline of the water dispenser is required to be thoroughly discharged, then the three-way pipe is connected with the water inlet pipeline of the cold water channel and the hot water channel, the ozone generator is started, ozone is enabled to enter the cold liner, the hot liner and the pipeline of the water dispenser to realize sterilization, on one hand, the operation steps are more complicated, on the other hand, the cleaned water dispenser has pungent smell residues, and the peculiar smell can be removed only by flushing with clear water for many times. In the prior art, water circulation is adopted to clean the flushing pipeline, but normal-temperature water flushing is adopted in the cleaning process, so that the sterilizing effect cannot be achieved. The cleaning agent is also matched with a professional cleaning solvent for use, and as is well known, any chemical agent is easy to clean and has residues, and a large amount of water is required to be repeatedly used for removing the residues of the pharmaceutical agent. The method has the advantages that the operation is complex, and medicine residues are easy to cause and are unfavorable for healthy drinking water.
