Water server and air sterilization chamber for water server

Abstract

In order to effectively sterilize air that comes into contact with drinking water in a water server, an air sterilization chamber (23) is used, said air sterilization chamber (23) comprising: a case (26) having an air inlet (24) and air outlet (25); an air chamber (27) formed inside the case (26); an ozone generator (30) that converts oxygen inside the air chamber (27) to ozone; an air inflow channel (28) that communicates between the air inlet (24) and the air chamber (27) via an ozonolysis filter (32) on the inlet side which is positioned above the air chamber (27); and an air outflow channel (29) that communicates between the air chamber (27) and the air outlet (25) via the an ozonolysis filter (33) on the outlet side which is positioned above the air chamber (27).

Description

technical field [0001] The present invention relates to a water dispenser for supplying drinking water from a water bottle filled with drinking water such as mineral water. Background technique [0002] In recent years, water dispensers have been installed in offices, hospitals, etc. Generally, a water dispenser puts part of the drinking water in a detachably installed water bottle into a cold water tank built into the water dispenser, and pours the drinking water cooled in the cold water tank into a paper cup or the like for use. [0003] However, when drinking water is poured out from the water dispenser, the water level in the cold water tank built in the water dispenser drops, and air enters the cold water tank from the outside in accordance with the drop in the water level. At this time, if bacteria enter together with the air, there is a possibility that bacteria may be mixed into the drinking water in the cold water tank, which is not preferable in terms of hygiene. ...

AI Technical Summary

Problems solved by technology

Therefore, it is difficult to increase the ozone concentration in the housing 41, and there is a possibility that the air passing through the housing 41 cannot be sufficiently sterilized.

[0009] In addition, in the air sterilization chamber 40 described in Patent Document 1, because the activated carbon filter 49 is disposed facing the uppermost air chamber 43, the ozone in the uppermost air chamber 43 contacts the activated carbon filter 49 and is decomposed. When there is no movement of air inside and outside the casing 41 (when drinking water is not poured from the water dispenser), there is also a problem that the ozone concentration in the uppermost air chamber 43 decreases.
