Description
Technical field
The present invention relates to a kind of bath articles, particularly relate to a kind of energy-saving water heater.
Background technique
In summer, people will almost have a bath everyday, for not installing solar water heater, gas heater, electric heater
Etc. the place of dedicated bath apparatus, such as students' dormitory, construction site, the problem of summer bathing difficulty is a long-standing problem.Separately
On the one hand, need to drink a large amount of cold water in summer people, usually by tap water it is boiled after cool down drink again, by hot boiled water
A large amount of heat is wasted during cooling down.
Summary of the invention
The object of the present invention is to provide a kind of energy-saving type heaters easy to use, can make the heat in tap water and vacuum flask
Water carries out heat exchange to generate bath hot water, can not only solve the problems, such as bathing, but also cold water can be obtained and drink；It both solves in this way
The problem that it is difficult that summer has a bath, and saved the energy.
To achieve the above object, the technical solution adopted by the present invention is that: a kind of energy-saving water heater, mainly by coil heat exchange
The composition such as device, valve body, the metal tube both ends of coil heat exchanger are installed on valve body, metal tube both ends respectively on valve body into
The mouth of a river is connected to water outlet, and tap water can flow into the inner cavity of coil heat exchanger from water inlet, and flow out from water outlet；Tap water with
Hot water in vacuum flask is not mixed, and only carries out surface heat exchange.
Above-mentioned energy-saving water heater, in use, can be connected to its water inlet on the tap of tap water by hose, by it
Water outlet is connected on shower nozzle by hose, and coil heat exchanger insertion is filled in the vacuum flask of hot water, tap is opened
Hot water can be flowed out on shower nozzle by regulating flow.Hot water after bathing in vacuum flask has become cold water, in the summer
Ji Yinyong is just right；Cold water has not only been obtained in this way, but also using the heat bathing of hot water, has reached energy-efficient purpose.
The effect of valve body is to fix the both ends of coil heat exchanger, and formed by water inlet, coil heat exchanger, water outlet group
At heat exchange water route.The material of valve body is metal or engineering plastics, and valve body can use integral structure, can also use and divide
Body modular construction；The valve body for such as using engineering plastics, can be directly injection-moulded in together with coil heat exchanger；As using metal

Further, in order to keep water flow adjustable, throttle valve can be set in the water inlet or water outlet of coil heat exchanger, leads to
The size of flow can be closed, opens water flow and control by crossing the throttle valve；The throttle valve can both have been made integrally with valve body,
Commercially available universal valve can be selected and be assembled together with valve body.
Further, in order to keep water temperature adjustable, a cold water bypass in parallel with coil heat exchanger can be set on valve body,
Manual temperature valve is set in the entrance or exit of coil heat exchanger and cold water bypass, can be adjusted in synchronism by manual temperature valve
The flow proportional of hot and cold water, i.e., when the flow in a water route increases, another water route flow reduces, and is maintained at bath water-temperature
Suitable temperature；The size of total flow can also be closed, open and be adjusted to the manual temperature valve.
Further, in order to keep water temperature constant, a cold water bypass in parallel with coil heat exchanger can be set on valve body,
Constant-temperature water mixing valve is set in the exit of coil heat exchanger and cold water bypass, constant-temperature water mixing valve can be mixed according to hot and cold water
Leaving water temperature automatically adjusts the flow proportional of hot and cold water, so that bath water-temperature is maintained at stationary temperature, i.e., when the temperature of bath water
When higher than set temperature, constant-temperature water mixing valve reduces the flow of hot water automatically and increases the flow of cold water simultaneously, and water temperature is made to remain steady
It is fixed；Conversely, constant-temperature water mixing valve reduces the flow of cold water automatically and increases heat simultaneously when the temperature of bath water is lower than set temperature
The flow of water makes water temperature maintain to stablize；Constant-temperature water mixing valve can both make integral with valve body, can also be fabricated to and valve body
Removably；Constant-temperature water mixing valve is mainly made of temperature-sensitive element, spool, valve body, spring, Thermal Control Element etc., and temperature-sensitive element can be with
It is marmem or thermometer bulb, temperature-sensitive element variation with temperature and dilatancy simultaneously push spool mobile, automatically adjust cold
The ratio of hot water；Thermal Control Element can be screw or knob, by the rotation adjustable spring of Thermal Control Element to temperature-sensitive element
Pressure, and then adjust the temperature of bath water.
The invention has the advantages that can both be solved in summer using the heat tap water of hot water in vacuum flask
The problem of bathing, drinkable cold water of having got back are energy saving and provide convenience for people's lives.
