technical field

The invention relates to a water-saving system, especially an automatic circulation water-saving system for residential buildings, office buildings, hotels, hotels and school teaching buildings.

Background technique

At present, the current situation of water shortage is well known, and there is a long way to go to save water. But at present residential buildings, office buildings, school teaching buildings, guesthouses, hotels, etc. clean, clean and bath water are directly discharged into the sewer pipes after use, while flushing of public toilets in toilets and residential quarters, and sanitation around buildings Clean tap water is used in occasions that do not require clean tap water, such as cleaning, car washing, watering of green belts, water replenishment of ditches and lakes. These all cause great waste of water resources. On the other hand, when it rains, the rainwater on the roof of the building runs off in vain. Based on the above considerations, if it is possible to collect the used water in residential buildings, office buildings, hotels, hotels, and school teaching buildings except for toilet flushing, mop cleaning, and ground cleaning, as well as rainwater falling into the roof when it rains, After filtration, deodorization, sterilization and disinfection, it can be used for sanitation and cleaning in buildings, toilet flushing and sanitation around buildings, car washing, irrigation of green belts, water supply of creeks and lakes, flushing of public toilets, Fire protection, etc., can greatly improve the reuse rate of water and reduce the discharge of waste water. This is not only in line with the current national energy conservation and emission reduction policies, but also produces good social, economic and environmental benefits.

Though, also disclose and authorize some patents about building water saving at present. After searching, the only patents similar to the concept of the utility model are the utility model "water-saving device for buildings (authorized announcement number: CN2723526Y)" and the utility model "water-saving device for residential buildings and buildings (authorized announcement number: CN2443055Y)", but they are in There are also the following defects in the water-saving effect and use:

1. Water tanks need to be installed between the two floors of the building. On the one hand, it occupies space, reduces the net height of the lower floor, and increases the cost of the building;

2. Since the flushing water on each floor comes from the cleaning and bathing water on the upper floor and the rainwater collected on the roof. When the upper floor provides little or no water, and there is no rainwater replenishment, the lower floor can only use clean tap water for flushing;

3. The cleaning water in the kitchen was not collected. This part of the water takes up a large part of the water, especially in the kitchens of hotels and guesthouses;

4. It cannot realize the automation of the water level detection of the water tank and the switching of the tap water and the secondary waterway, which does not conform to people's water habits;

5. Only consider the water saving problem of a single building, and do not address the overall water saving (such as the saving of water required for irrigation of green belts, environmental cleaning, etc.) workable solution.
