Description

Hot water intelligent circulation system

Technical Field

The intelligent hot water circulation system is intelligently started by taking a human behavior mode as a logic judgment target, integrates functional accessories to avoid engineering reconstruction after decoration, and forms a set of complete intelligent hot water circulation system.

Background

Along with the enhancement of the overall environmental protection consciousness of the society, the circulation before water is used to effectively avoid the generation of abandoned water. However, this circulation often requires dedicated return pipe support to achieve. The need to destroy the finished installation duct is difficult for the finished user. An alternative is to bridge the cold and hot water lines with a check valve. This bridging first causes mixing of the hot water when cold water is used alone, which makes it impossible for people to enjoy the cooling of cold water alone in the hot summer season. Meanwhile, the bridging of the basin faucet is convenient to realize, and the bridging equipment cannot be installed on the wall-mounted shower faucet. And if the timing cycle is adopted, the pipelines of each terminal device are different in length, and the pipelines are either not circulated or circulated overtime, so that the energy is wasted after each month. The existing water-controlled starting and manual starting have great inconvenience. This patent aims at solving above problem, makes this kind of application more convenient, saving and intelligent.
