Abstract: A sink applied to a system for recovering and reusing graywater includes a sink body, including a water basin located at an upper part of the sink body and a cavity located at a lower part of the sink body. The water basin comprises a water outlet configured to be connected to a sewer. The sink also includes a sink graywater recovery pipeline configured to be connected to the water outlet. The sink also includes a washing device configured to be connected to the sink graywater recovery pipeline. The sink also includes a switching device configured to switch between the sewer and the sink graywater recovery pipeline. When the switching device opens the sewer and closes the sink graywater recovery pipeline, the graywater is led into the sewer and discarded. When the switching device opens the sink graywater recovery pipeline and closes the sewer, the graywater is led into the washing device.

Abstract: The present disclosure provides a system for recovering and reusing graywater generated from at least one graywater source in a building. The system includes a controller configured to control recovery and reuse of the graywater; a graywater recovery device communicably coupled to the controller and configured to recover the graywater from the graywater source of the building; and a graywater distributor communicably coupled to the controller, connected to the graywater recovery device, and configured to distribute the recovered graywater to at least one target position in the building for reuse, wherein the controller controls the graywater recovery device to deliver the graywater to the graywater distributor according to a control signal sent by a user, and the controller controls the graywater distributor to deliver the graywater to a target position designated by the user for reuse according to a control signal sent by the user.
