| 摘要 |
The invention relates to a device (2) for drinking water purification, having a water tank (4) for receiving the drinking water (6) to be purified, a pump (8) for transporting the water, and a membrane filter unit (10) which comprises a water inlet (12), a membrane filter (14), a pure water discharge (16), and a rinsing water discharge (18). The water inlet (12) is supplied with water directly or indirectly from the water tank (4) via a feed line (24), and is disposed in the flow direction (19) in front of the membrane filter (14). The pure water discharge (16) is disposed in the flow direction (19) behind the membrane filter (14). To remove deposits, part of the water fed to the membrane filter unit (10) via the water inlet (12) is guided across the membrane filter surface and exits the membrane filter unit (10) via the rinsing water discharge (18). In order to increase user friendliness, a water return line (26) connects the rinsing water discharge (18) to the water tank (4). Furthermore, the water tank (4) can be removed from the device (2) and filled with drinking water. |
