Description

Residential Water Saving System

technical field

The invention relates to a water supply and drainage connection structure, water-saving technology and control technology of sanitary ware for houses, and in particular to a water-saving system for houses.

Background technique

With the increasing shortage of water resources, saving water and making full use of water resources has become a common research topic at home and abroad. At present, many cities in our country are seriously short of water, which affects the normal life of residents. Household water saving is an important part of water resource conservation, but it is more difficult to actually save house water, because it is difficult to save necessary house water. In order to save house water, countries all over the world have researched and developed water-free toilets, biological toilets, vacuum toilets and microcomputer automatic environmental protection toilets and other water-free toilets, but these toilets are expensive and difficult to popularize.

In order to reuse the waste water from house washing, some households store vegetables and face water in buckets, and flush the urinal backwards. On the one hand, it is inconvenient, and on the other hand, it is easy to splash dirt on the body. Although there are already buildings and residential wastewater reuse equipment and solutions, they are aimed at the overall environmental protection of the society, and require a large investment and occupy a lot of land. It is not intuitive to save water for residential use, and the economic benefits are not obvious. The water-saving device disclosed in the patent No. 01250003.8, named "Household Water Saving Tank" and the application No. 200610005313.1, named "Household Sanitary Ware Water-Saving Connection Structure and Device" mainly has the following deficiencies: 1. The degree of renovation of the toilet is large, The feasibility is not high; 2. The connecting pipes are more complicated, there are many pipes passing through the floors between the upper and lower floors, and the renovation is difficult and costly; 3. The lack of washing wastewater is not considered, and the operation is required, and the function is not good Perfect and inconvenient; 4. The installation location requirements for related appliances are relatively strict, which is not conducive to popularization.

At present, house washing wastewater can be used to flush mops and urinals, but most of this water is wasted at present.

Contents of the invention

The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a house water-saving system that can be used not only for a single family but also for a whole building, and can store all the washing waste water in the house for reuse.

In order to achieve the above object, the technical solution adopted in the present invention is: comprise the vegetable sink, the wash basin, the bath basin, the urinal flush tank and the running water pipeline and the common water pipes that produce waste water; The outlet of the water outlet and the outlet of the bathing pool are respectively connected to the waste water pipeline extending downwards, and the lower end of the waste water pipeline is connected with the waste water filter tank through a filter screen; The check valve is connected with the waste water pipe extending upwards, and the upper end of the waste water pipe is connected with the waste water reservoir located at the highest position, and the waste water reservoir is connected with the urinal flushing tank through the waste water pipe; Connected to the waste water pipeline; the control box is connected to the water pump through the signal line/control line, connected to the liquid level gauge in the waste water filter tank through the signal line, connected to the electric valve through the signal line/control line, and connected to the urinal flushing tank through the signal line The liquid level gauge in the tank is connected with the liquid level gauge in the waste water storage tank through the signal line.
