Abstract
A germfree drinking water dispenser includes a reservoir for receiving and reserving drinking water such as mineral water and an ozone injecting device. The ozone injecting device includes a compact ozone generator and an injection opening which is opened into the reservoir. Ozone generated by the ozone generator is injected, by e.g. a blower, through the injection opening into the drinking water at the reservoir. The ozone injecting device is activated only for a short necessary period of time when the dispenser is out of service. So that, after the drinking water in the reservoir is fully sterilized, a sufficient period of time is allowed to lapse for any ozone remaining in the water to dissolve until the next first use of the dispenser.
