Description

Water-saving device based on existing family arrangement and capable of being simply and conveniently installed on hot water faucet

Technical Field

The invention relates to a water-saving device, in particular to a water-saving device which is based on the existing household waterway pipeline arrangement and can be simply and conveniently arranged at the tail end of hot water supply such as a hot water faucet.

Background

In daily life, a water heater is usually away from hot water taps such as showers and kitchens by a certain distance, when the hot water taps are opened, residual cold water in a pipeline can only be drained firstly, and the water quantity to be drained every time is 2.8 liters, wherein the distance is 10 meters, and the water pipe with the diameter of 25 millimeters and the wall thickness of 3 millimeters is commonly used in families. This results in a large waste of water resources.

There are three main types of solutions currently being searched: the type is that a water return loop and a water return device are laid, and water in the pipeline is kept to be heated at any time in a mode of continuously returning water and reheating by a water pump to wait for use. The second type is to provide a recycling pipeline for recycling the cooling water in the pipeline to the toilet and the like (for example, patent No. CN 108201392 a). The third type is that a three-way butterfly valve and a water storage tank are arranged on a pipeline near a faucet, and a valve is operated in advance to recycle cooling water in a manual control mode before the water storage tank is used (for example, the patent number is CN 204678473U).

The technology of the type I is mature and commercial, the running of the equipment needs to continuously consume energy to maintain the running of the return water pump and the heater, a relatively complex return water pipeline needs to be erected, the comfort is good, and the economic effect and the energy-saving effect cannot be balanced. The second type needs to erect longer and complicated recycled water pipelines, needs to arrange a plurality of electromagnetic valves, water pumps and pressurizers, and even needs to modify the mode of the water heater to realize the purpose of water saving. The third type is energy-saving, but the broken pipe installation is also complex, and the normal use experience of the user for opening and using the hot water faucet is damaged. The living and learning cost is improved.

The prior art cannot achieve balance in economy and energy conservation, and needs complicated line reconstruction and construction. The problems of water saving, electricity consumption and gas consumption in real life are caused, the technology implementation and installation construction are complex and difficult to popularize, the water consumption problem is objective and difficult to solve for a long time, and the like.
