Problems solved by technology
[0004] For the boiler hot water centralized supply device used in hotels and guesthouses, the laying of super long and super large pipelines will retain more water, resulting in a huge amount of cold water wasted when passengers open the water valve to use hot water.
[0005] Even if the instant hot water faucet was invented in reality, the developer even installed the heater at the water outlet, but it still cannot overcome the waste of water resources caused by the discharge of cold water during the temperature rise process.
[0006] Some technical inventions for realizing zero-cold water in water heaters today, such as CN 104566928A and CN106369807A, either design special pipelines or lay complex pipelines, which pushes up the manufacturing and installation costs of products, and without exception, users need to use them in reality. Abandon the hot water supply device and buy a new hot water supply device at a high price, which is extremely unfavorable for promotion and cannot produce extensive social benefits

Embodiment Construction
[0018] Attached below figure 1 And the specific embodiment describes the present invention in detail:
[0019] For the hot water supply device (4) in which the water flow switch controls the heater to work, when the bather enters the bathing place, it is first sensed by the remote infrared sensor (701) of the human body, and the controller (7) opens the electric control shut-off valve (2 ), and start the circulating water pump (1) at the same time, the retained water in the hot water pipeline closed at the front end of the manual mixing valve (6) will flow through the electric control shut-off valve (2) and the circulating water pump ( 1) The cold water pipeline of the manual water mixing valve (6) is discharged into the tap water pipe network in the individual area of the hot water supply device (4). Under the action, it is effectively used and discharged from this node. When there is no node for cold water use, the retained water will circulate in the electric control shu...

The invention provides a zero-cold-water water-saving assisting device for bathing. The zero-cold-water water-saving assisting device for bathing is composed of a circulating water pump (1), an electric control stop valve (2), a temperature sensor (3), a hot water supply device (4), an electric control stop valve (5), a manual water mixing valve (6) and a controller (7). The zero-cold-water water-saving assisting device is characterized in that the device is integrally installed on the manual water mixing valve (6) and is connected with a cold water end and a hot water end of the manual water mixing valve (6), the hot water supply device (4) used in reality does not need to be replaced, and functions of zero-cold-water hot water supply and water saving in the water supply process are achieved.
Description
technical field [0001] The invention belongs to an auxiliary device for realizing zero-cold water and saving water in a hot water supply system for bathing in daily life. Background technique [0002] In real life, the hot water supply system commonly used by people for bathing, because its inlet is directly connected to the outside tap water, when the water outlet valve is opened, the retained water in the pipeline will be discharged outward under the action of water pressure, and the water in the hot water supply system There is a gradual temperature rise process from start-up to normal operation of the heater, which eventually leads to a considerable amount of cold water that cannot meet the requirements of human use and is wasted. [0003] For household bathing and haircutting and shampooing, often because the installation position of the hot water supply device is far away from the water outlet valve, there is more water retained in the pipeline, and the amount of cold ...
