Description
Technical field
The utility model relates to a kind of solar water heater, and particularly a kind of reinforcement heat-insulating property guarantees water tank volume and efficiency grade, avoids high temperature evaporation to cause the solar water heater of energy and water yield loss.
Background technology
Common solar water heater is nonbearing structure, generally is provided with overflow pipe and atmosphere.After water temperature raises, after the hot water volumetric expansion, exceed the part high-temperature-hot-water of water tank nominal volume, directly to discharge outdoor through overflow pipe, this just causes the loss to the absorption solar energy; Especially for the solar water heater that adopts electric assistant heating, this directly causes the additional waste of user's electric energy; The discharge of swelling water also forms the loss and the waste of water simultaneously.After hot water cooling cooling, the actual capacity of water tank and efficiency grade on the low side.Therefore, the actual water capacity of at present common solar water heater all generally is lower than the 5%-10% of water tank theory volume, and the efficiency of solar water heater and user's comfort are affected.
Summary of the invention
For solving the above problems, it is a kind of when can effectively improve the solar water container heat insulation effect that the present invention provides, and guaranteed the water tank water capacity, avoided the solar water heater of the waste of energy and water.
The utility model technical problem to be solved is to realize through following technical scheme: a kind of solar water heater; Comprise solar water container, level sensor and water inlet pipe and water outlet pipe joint; Said level sensor is located in the solar water container, and is that said water inlet pipe and water outlet pipe joint is located at solar water container bottom and be communicated with it; It is characterized in that also comprising expansion tank, be provided with a tube connector in said solar energy water box top, solar water container is connected with expansion tank through tube connector, on expansion tank, is provided with a passage, said passage and atmosphere.
Top in said expansion tank is provided with condensate tank(trap).
Outside at said solar water container is provided with heat-insulation layer, is provided with heat-insulation layer in the outside of said expansion tank.
The volume of said expansion tank is more than or equal to the maximum swelling water yield of water in the solar water container.
The utility model beneficial effect compared with prior art is: through the increase-volume of expansion tank; After having solved the water storage expanded by heating of regular solar water heater; The hot water overflow causes the problem of the waste of energy and water resource, has guaranteed water capacity, has realized the full water Capacity design that water tank is real.Simultaneously, overflow pipe and blast pipe through on the cancellation regular solar water-heater water tank make the water tank heat preserving effect significantly improve.In addition,, realized the condensing reflux of high-temperature water vapor, also guaranteed water volume in water tank to a great extent through the condensing unit in the expansion tank.The beneficial effect of the final concentrated reflection of the present invention is obviously to have improved the comfort level that the actual water capacity of solar water heater, the high heat insulating ability of having realized solar water container, the efficiency of having guaranteed solar water heater and user use.

Fig. 2 solar energy heating view of the present invention;
Fig. 3 solar energy high temperature vapor state of the present invention sketch map.
The specific embodiment
To combine accompanying drawing and embodiment that the utility model is done further detailed description below.
As shown in Figure 1, a kind of solar water heater comprises solar water container 5, level sensor 7 and water inlet pipe and water outlet pipe joint 6, and said level sensor 7 is located in the solar water container 5, and is that said water inlet pipe and water outlet pipe joint 6 is located at solar water container 5 bottoms and be communicated with it; The utility model characteristics are also to comprise expansion tank 3; Be provided with a tube connector 4 at said solar water container 5 tops; Solar water container 5 is connected with expansion tank 3 through tube connector 4, on expansion tank 3, is provided with a passage 31, said passage 31 and atmosphere; Passage 31 can be guaranteed solar water container 5 normal Inlet and outlet waters, and the side of solar water container 5 and other positions all do not have perforate.
In the present embodiment, the top in said expansion tank 3 is provided with condensate tank(trap) 2.Be provided with heat-insulation layer 51 in the outside of said solar water container 5, be provided with heat-insulation layer 32, realized strengthening the effect of insulation through heat-insulation layer in the outside of said expansion tank 3.The volume of said expansion tank 3 is more than or equal to the maximum swelling water yield of water in the solar water container 5.
During use, water level is a full water on the setting sensor 7, and it is full through water inlet pipe and water outlet pipe joint 6 cold water to be injected solar water container 5 to water.This moment is anhydrous in the expansion tank 3, only to 4 insulation effects of tube connector at solar water container 5 tops.
As shown in Figure 2, after absorbing solar energy, water temperature raises gradually, and the swelling water that volume increases behind the water expanded by heating in the solar water container 5 gets into expansion tank 3.This moment, 3 pairs of swelling waters of expansion tank and water inlet pipe and water outlet pipe joint 6 played insulation effect simultaneously.After water temperature descended, swelling water was back to solar water container 5 inside gradually.
As shown in Figure 3, continue to rise like solar water-temperature, reach boiling point; Operative liquid water vapor this moment forms the steam come-up; In the come-up through the time through the inwall of lower condensate tank(trap) 2 of excess temperature and expansion tank 3, i.e. condensing reflux, the uncooled steam of part will be through passage 31 discharges.
During water, the hot water in the solar water container 5 flows out through water inlet pipe and water outlet pipe joint 6, and air outside gets into expansion tank 3 tonifying Qi through passage 31 simultaneously, guarantees normal water outlet.
