This invention discloses a rotatable three-chamber
liquid storage and diversion washbasin device, belonging to the technical field of bathroom water-saving equipment. The device consists of a supporting base column and an upper
assembly. The bottom of the supporting base column is hollowed out, allowing for the free installation of expansion components. A buried
water pipe is installed in the center, and a
cement counterweight can be poured into the outer rotating shaft cavity of the
water pipe to achieve stable installation without exposed pipelines. The upper
assembly adopts a symmetrical structure, allowing for bidirectional
assembly and rotation relative to the base column for switching functions. Internally, it has three independent chambers: a low-temperature
water storage chamber, a
clean water storage tank, and a
wastewater collection tank, enabling circulating water and achieving passive, natural low-temperature
water storage. It also features an isolated storage drawer for low-temperature storage. The device is equipped with a triple one-way valve forming an anti-
backflow system, effectively preventing water
backflow pollution and
clean water overflow waste. The
wastewater collection tank has a micro-water replenishment port, enabling unattended pipeline moisturizing and automatic liquid replenishment. It also has a dual-
mode switching function for conventional
water collection and
clean water expansion, allowing for flexible adjustment of the
water storage capacity. The external inspection port facilitates the maintenance of internal valves and pipelines. The overall structure is compact and has a high space
utilization rate. It also features water and energy saving, flexible installation, strong expandability, and simple operation and maintenance. It can be widely used for integrated water-saving renovation of water-use spaces in hotel rooms, home kitchens and bathrooms, and small-sized water-use areas.
