Household water-saving system

Abstract

The invention discloses a domestic water saving system. The drain port of a sink, the drain port of a wash basin and the drain port of a bath are respectively connected to a waste water pipeline extending downwards. The lower end of the waste water pipeline is connected with a waste water filter tank via a filter screen; the overflow port of the waste water filter tank is connected with the waste water pipeline; the waste water filter tank is connected to a waste water pipeline extending upwards via a water pump and a check valve; the upper end of the waste water pipeline is connected with the waste water storage tank at the upmost position; the waste water storage tank is connected with a toilet flushing tank through the waste water pipeline; the tap water pipeline is connected with the waste water pipeline via an electromagnetic valve and a check valve; a control box is respectively connected with the water pump, the liquid level meter in the waste water filter tank, the electromagnetic valve, the liquid level meter in the toilet flushing tank, and the liquid level meter in the waste water storage tank. The invention can be used for both a single family and a whole building. The system has simple and practical structure, facilitating old building reconstruction and new building construction installation and providing interfaces for domestic electric intellectualization.

Description

technical field [0001] 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 [0002] 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 dif...

Saving house water is an important part of saving water resources, but it is more difficult to really save house water, because it is difficult to save the 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, etc., but these toilets are expensive and difficult to popularize

[0003] In order to reuse the washing wastewater for residential use, some households store vegetables, face washing water, etc. in buckets, and flush the urinal upside down. On the one hand, it is inconvenient, and on the other hand, it is easy to splash dirt on the body.

Although there are existing 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

[0004] At present, household washing wastewater can be used to flush mops and urinals, but most of this water is wasted
