Water distribution device with recirculation
By introducing a multi-valve-controlled water guiding and recirculation path into the water distribution device, combined with hollow fiber membrane and carbon block filtration, the retained water is selectively recirculated according to the retention time, which solves the problem of bacteria and biofilm in the water distribution device and achieves a reliable guarantee of high-quality filtered water.

AI Technical Summary
Existing water distribution devices are prone to generating bacterial loads and biofilms in stagnant water, and existing sterilization methods may lead to additional biofilm formation or chemical residues, making it difficult to ensure the high quality of filtered water.
The system employs multiple valves to control the water guiding and recirculation paths. Recirculation is triggered by user input. The filter unit, including hollow fiber membranes and carbon blocks, selectively recirculates retained water based on water retention time, thus avoiding the need for additional sterilization units.
It effectively removes contaminants and bacteria from the water distribution device, ensuring high quality of filtered water, reducing energy consumption and component load, and avoiding chemical residues and biofilm enhancement.
