Description

A kind of solar water heater

Technical field

The utility model relates to a kind of water heater, more particularly, and particularly a kind of solar water heater.

Background technology

In recent years, as the solar water heater of one of solar energy development technology of any particular energy source, because it is inexpensive, convenient, unique advantage such as practicality and non-environmental-pollution, pour in rapidly in the family of urban and rural residents, great convenience is provided to people's bathing and other domestic waters.But the water tank installation site of existing solar water heater is long apart from its use location water pipe, and the general outdoor use of solar water heater, hot water is long in the transmission range of water pipe, has caused the significant wastage of hot water.Current solar energy water heater device is generally first to add water to water-heater water tank by water supply pipe, then use the water in solar energy heating water tank, when concrete use by the water having heated and cold water mix again through shower nozzle water outlet, after temperature adjusting is suitable, use, general overview is three kinds of structures: the first is single hose solar water heater, its water tank is connected by same water pipe with mixed water valve, the shortcoming of this mounting means is to open after mixed water valve, because water tank is very long apart from use location, need the cold water that will put for a long time could derive hot water, capital of every use wastes the hot water remaining in water pipe in this case, and because the locality of the mixed valve switch of this kind of structure is inaccurate, to operating unfamiliar old man, child is easy to mistake hot water is used as cold water, cause old man, child is scalded by boiling water, also can cause the waste of the boiling water having heated in a large number simultaneously.The second is double hose solar water heater, its water tank with mixed water valve, circulating pump, upper water solenoid valve is two-tube is connected, but its start circulating pump cold water served to about more than a minute after hot water could flow out, after water stops, in pipe, hot water is cooled, again served water tank while use next time, the same with the first structure, and its waste hot water phenomenon is serious equally, waste energy simultaneously, and circulating pump cost is large, fault rate is high, uses extremely inconvenient.The third is to utilize exhaust-valve emptying, the mode of heating water again, its shortcoming is water supply valve, lower water valve and exhaust-valve do not cooperatively interact, user is difficult to grasp, be easy to cause spilling water, and due to reason being installed, U-shaped pipe is too many, ponding in water pipe is many, after shower, working as lower water valve and the exhaust-valve of insulation three-way magnetic valve closes, exhaust-valve is opened while carrying out draining, remaining water in water pipe is difficult to emptying, add water pipe diameter little, shower nozzle becomes U-shaped with water pipe, shower nozzle hole is very little, the resistance being subject to when hot water gets off is very large, so take a shower time at Yu Shui, under shower nozzle and air in tube reaction, hot water is difficult to get off from shower nozzle.

In sum, how to improve the efficiency of solar water heater, the heat-insulating property that strengthens its water tank becomes those skilled in the art's problem demanding prompt solution.

Utility model content

The technical problems to be solved in the utility model is for a kind of solar water heater is provided, and this solar water heater, by two different water tanks of height are set, has effectively been realized the storage problem of hot water, improves the efficiency of solar water heater.

For solving the problems of the technologies described above, the utility model provides a kind of solar water heater, comprise elevated tank and lower water box, described elevated tank is arranged at lower water box top, between described elevated tank and lower water box, be provided with connecting water pipe, it is characterized in that, described elevated tank top is provided with spillway hole, described spillway hole place is provided with breather valve, can reduce elevated tank heat leakage, breather valve cuts out at ordinary times, upper water, when lower water, open described lower water box and comprise inner core and urceolus, on described inner core and urceolus, be provided with corresponding inlet opening and apopore, described inlet opening is connected with elevated tank by water pipe, described apopore is connected with water pipe, between described inner core and urceolus, be provided with heat-insulation layer.By elevated tank and lower water box are set, shorten the length of the pipeline of need flowing through when hot water uses, the outlet pipe that only need arrange at lower water box apopore place connects bath head or tap can use, because lower water box is provided with inner core, urceolus and middle heat-insulation layer, therefore strengthened greatly the heat-insulating property of solar water heater, meanwhile, because elevated tank top is provided with corresponding spillway hole and breather valve, can effectively guarantee that the gentle pressing of water level of elevated tank and whole device is steady.

General 0.31 above thickness stainless steel, epoxy tree interior bucket yesterday of adopting of non-bearing type solar water heater made, and can bear the pressure of 0.09 MPa (suitable 0.9 kilogram) left and right, the inner bag of pressure-bearing type solar water heater adopts corrosion resistant plate more than 0.6 thickness, or other enamel inner bag, can bear the above pressure of 0.25 MPa (suitable 2.5 kilograms), and the electric heating hot water of prior art generally belongs to bearing type water tank, bearing type water tank is because its structure arranges, electric heater and the water-temperature water-level detector of solar water heater cannot be conveniently installed, and use and maintenance is inconvenient to facilitate, below the utility model lower water box is arranged on, only rely on elevated tank pressure-acting in lower water box, pressure that lower water box bears less (being less than 0.09 MPa), described lower water box is non-bearing type water tank.

In order better to realize heating to cold water and the real-time monitoring of water temperature, simultaneously in order to facilitate laying of heater and regulation device, on described lower water box, be provided with heater mounting hole and temperature sensor installing hole, in described heater mounting hole, be provided with heater, in described temperature sensor installing hole, be provided with temperature sensor, described heater is connected with the control system of outer setting with temperature sensor.

Realize monitoring for the water level in elevated tank, in described elevated tank, be provided with level sensor, described level sensor is connected with the control system of outer setting.

In order to realize mixing of cold water and hot water, under the water pipe that described lower water box apopore place arranges, be connected with constant-temperature water mixing valve, described constant-temperature water mixing valve place is also provided with cold water inlet.

For upper water, simultaneously in order to prevent that high-temperature-hot-water from entering running water, between described constant-temperature water mixing valve and lower water box, be also provided with water solenoid valve.

In order to prevent the generation of the inner incrustation scale of inner core, described inner core is stainless steel inner core or epoxy resin inner core.

The beneficial effects of the utility model are: by elevated tank and lower water box are set, and the length of the pipeline of need flowing through while having shortened hot water use, really accomplishing to open is exactly hot water, extremely easy to use; Owing to there being two water tanks, increase hot water memory space; Lower water box is provided with inner core, urceolus and middle heat-insulation layer, add perforate few, and be placed in indoor, do not expose to wind and rain, heat runs off less, therefore strengthened greatly the heat-insulating property of solar water heater, made lower water box in the time that indoor temperature is zero degree left and right situation, reach in 24 hours temperature 2 degree that only decline; Because water temperature can keep for a long time, therefore can avoid heater frequently to heat the water in lower water box, cause the waste of electric energy, adding the water that enters lower water box by elevated tank is generally hot water, be easy to be heated to normal serviceability temperature, saved a large amount of electric resources.
