Description
Technical field
The present invention relates to the constant temperature water supply system, particularly a kind of constant temperature energy-saving water system that has access to hot water and cold feed water source.
Background technology
People need the hot water of design temperature in daily life when being used for shower or other domestic waters.Hot water is usually through gas heater, electric heater or solar water heater supply; Cold water is directly provided by the water service system; When needing the hot water of design temperature, the hot water that provides of water heater often can not directly use, but also need mix behind the cold water to reach ideal temperature.The water of this design temperature is generally realized through dual mode; A kind of mode is that the mode that adopts artificial mixed water regulating valve that the quantity delivered of hot and cold water is regulated realizes; Another kind of mode is the water admixing device that a band thermostatically-controlled equipment is set; Automatically realize the adjusting of design temperature through control device and magnetic valve, make the leaving water temperature of water admixing device keep constant.Yet water heater is to must connecting through the pipeline of certain-length with the water spot position, after water finishes usually; The hot water that stores in the pipeline of water heater water side can cool off by nature gradually; When water next time, at first be that cold water in this pipeline is emitted with the water outlet of water spot, because the cold water of emitting earlier can not satisfied temperature requirement; This part water perhaps can be wasted, and causes water resource waste; Perhaps with container to use it for anything else, cause operational loaded down with trivial details.The long more foregoing problems of the pipeline of water heater water side seems serious more, particularly adopts gas heater when the shower room water, and from the factor on the safety, this section pipeline all is provided with longly especially, and the cold water of front end pipeline is many especially, and foregoing problems is particularly outstanding.
Summary of the invention
The object of the invention is exactly the deficiency to prior art, the constant temperature energy-saving water system based on external cold and hot water source that provides the cold water in a kind of water heater front end pipeline in time to utilize.
For realizing above-mentioned purpose, the present invention adopts following technical scheme:
