Washbasin-closestool composite water-saving device

Abstract

The invention relates to a washbasin-closestool composite water-saving device, comprising a washbasin, a water storage tank and a closestool, wherein the washbasin is provided with a water outlet; the water storage tank is provided with a water inlet pipe and a water outlet pipe, and the water inlet pipe is communicated with the water outlet of the washbasin; the closestool is provided with a dirty water flushing tank and a dirty water control valve used for controlling the dirty water flushing tank, and the dirty water flushing tank is communicated with the water outlet pipe of the water storage tank. The invention is characterized in that a clear water flushing tank is arranged above the dirty water flushing tank, a flush pipe of the clear water flushing tank is connected to the interior of the closestool and is controlled to open or close by a clear water control valve. Compared with the prior art, the invention has the advantages that the dirty water flushing tank is lowly positioned and is used frequently, thereby saving water resources; and the clear water flushing tank is the auxiliary supplement for the dirty water flushing tank and is highly positioned, and the drop height is large, thereby contributing to flushing and lowering the requirement on water capacity; and therefore, the capacities of the dirty water flushing tank and the clear water flushing tank are reduced, thereby effectively reducing the manufacturing cost and the installation space.

Description

technical field [0001] The invention relates to a water saving device, more specifically a water saving device combining a washbasin and a toilet. Background technique [0002] Usually there is a washbasin and a toilet in the bathroom, both of which are usually independent and each has a water supply and flushing system. In fact, it is a bit wasteful to drain the water used up in the washbasin directly, and it is a good idea to use it as a toilet flush The idea, which can save a lot of water resources. [0003] For this reason, many schemes of implementing this idea have occurred in the open literature, as the Chinese invention patent application publication "toilet water-saving system device" (publication number: CN101191342A) that is 200610097703.6 as the application number; Utility model patent "Secondary Application Device of Toilet Water Source" (authorized announcement number: CN2905917Y). Similar reference can also be made to ZL200420063415.5, ZL200620093087.2, ZL20...
