Background
In a traditional residential indoor water supply system, a cold and hot water supply system generally adopts a total branch system, and each water using branch pipe is branched from a main pipe and reaches a water using point without circulation. Because water only can follow the water spot outflow, when not using water, the water in the water supply system pipeline then becomes "stagnant water", breeds the bacterium easily, wherein hot water supply pipeline threatens the user healthy because the bacterium is bred especially easily to the temperature relation, and this leads to need to emit more "sewage" when using time, and consuming time and wasting water resources, if the pipeline inner wall gathers the bacterium then hardly to handle.
Some inventors have proposed some solutions to the above problems, for example, the invention patent with the name of "a closed full circulation water supply system and a water supply mode of domestic drinking water" disclosed in publication No. CN110185100A includes a water storage container, a water outlet pipeline, a water return pipeline, a water tap and a water supply pump, the water tap includes a water inlet, a water intake and a circulation water outlet, the water storage container is communicated with a water source, the water storage container is connected with the water inlet of the water tap through the water outlet pipeline, the circulation water outlet of the water tap is connected with the water storage container through the water return pipeline, circulation power is provided by the water supply pump, so as to realize water supply circulation, that is, water in the water supply pipeline is allowed to continuously flow, and generation of "dead water" is avoided. However, the present invention has a certain disadvantage that the water outlet pipeline and the water return pipeline are a main branch pipeline system, wherein the main pipeline needs to pass through the vicinity of each water tap (one of the water taps is directly connected), and the nearby branch pipeline on the main pipeline is connected with the water tap. When the number of the water taps is large, particularly when the distribution situation is complex, the positions of the water taps need to be considered for the pipe running of the main pipeline, the arrangement of the branch pipes needs to be considered, the whole pipeline system is complex, the difficulty is high during installation, and the pipeline is inconvenient to maintain when in use due to faults.
