Definitions
- the present invention relates to a method for flushing a piped drinking water dispenser which has a drinking water treatment unit connected to a drinking water supply, a tap fitting connected to the drinking water treatment unit, at least one connecting line through which the drinking water treatment unit is connected to the tap, and a control and Input system that is set up to issue control instructions to the drinking water treatment unit and the tap fitting.
- the present invention relates to such a piped drinking water dispensing device, whose control and input system is set up for carrying out such a method.
- a drinking water dispensing device is understood to mean a soft drinks machine which dispenses drinking water.
- Such drinking water delivery devices are known in the prior art. They usually give off unrefrigerated or ge chilled, still or carbonated drinking water.
- the piped drinking water dispensing devices are connected to the water supply of a drinking water supply network.
- the water is in large water containers that are attached airtight to the water dispenser.
- the drinking water from the drinking water supply network is not sterile, even with high drinking water quality, and always has a certain concentration of germs.
- Line-bound drinking water dispensers can therefore die despite good water quality. Therefore, germs also get into the water-carrying components of the drinking water dispenser with the water that is supplied to the drinking water dispenser.
- the risk of contamination occurs in particular in the water filter connected upstream of the drinking water dispenser, in which the germs contained in the drinking water are taken up. The germs that can grow there can then enter the line penetration system of the drinking water dispensing device.
- the fluid-carrying components contained in the drinking water dispensing device are not used continuously and thus not continuously rinsed, there is a risk that deposits will form in the liquid-carrying components of the piped drinking water dispensing devices or that microorganisms such as bacteria, for example Legionella or Pseudomonas, will form that pose a health hazard to humans.
- microorganisms such as bacteria, for example Legionella or Pseudomonas
