Water-saving facility

Abstract

The invention especially relates to a water-saving facility. The water-saving facility comprises a plurality of floor drains located in a upper-layer room, wherein the floor drains are connected with a water storage tank through a U-shaped pipe, the water storage tank is arranged in a wall body between the upper-layer room and a lower-layer room and is connected with a sewer pipe, the water storage tank, a closestool in the lower-layer room and a tap water system are connected through a three-way connector, a waste water valve is arranged between the water storage tank and the three-way connector, a tap water valve is arranged between the three-way connector and the tap water system, and a bottom lid is arranged at the lower portion of the water storage tank. Waste water firstly enters the water storage tank and then enters the sewer pipe after the water storage tank is full of water. Due to the fact the waste water from upper-layer residents is used by lower-layer residents, electricity is not needed under the gravity effect, namely waste water reutilization can be achieved. In addition, waste water produced from one of the upper-layer residents in one day is completely sufficient for closestool flushing of one of the lower-layer residents, real water and electricity saving is achieved, and the arranged U-shaped pipe avoids production of indoor bad smell, and the water-saving facility is simple in structure and convenient to use.

Description

(1) Technical field [0001] The invention belongs to waste water recycling, in particular to a water-saving facility. (2) Background technology [0002] On September 12, 2015, Ru Chaogui applied for a water-saving toilet. The toilet has a water tank under the shower room. The water flowing out of the shower head flows into the water tank through the drain outlet on the floor of the shower room after gathering, and the water tank passes through the flushing pipe. It is communicated with the toilet, a toilet drain valve is arranged at the water inlet end of the flush pipe, and a water pump is arranged on the flush pipe, and the water pump and the toilet drain valve are controlled by the drain key. When flushing the toilet, press the drain button, the toilet drain valve will open, and the water will be drained according to the preset displacement. [0003] The capacity of the above-mentioned water-saving toilet tank is limited, and the tap water system needs to be used from tim...

AI Technical Summary

Problems solved by technology

[0003] The above-mentioned water-saving toilet tanks have limited capacity, need to use the tap water system from time to time, and cannot make full use of the waste water from the households, and the water-saving effect is limited, which needs to be further improved

[0004] And the above-mentioned water-saving toilet has a fatal shortcoming that it cannot be used when there is no electricity, and it cannot achieve complete energy saving and water saving. This situation needs to be improved urgently.
