The utility model is achieved through the following technical solutions.

Show as Fig. 1.Base plate 1 is made heat-insulation and heat-preservation, and plate 7 is placed on the upper surface of base plate 1; The end face of interior conical shell 5 is connected in the upper surface of plate 7; Interior conical shell 5 usefulness light transmissive materials or Heat Conduction Material are made, if when making of Heat Conduction Material, being coated with existing high solar absorptance at its outer surface has the selective coating material of low radiance again or paint dark color (blackish green, be coated with coating such as dark, indigo plant); If interior conical shell 5 usefulness light transmissive materials are made, then be coated with the selective coating material or paint dark color in the upper surface of plate 7; The end face of outer conical shell 3 is connected in the upper surface of base plate 1, and outer conical shell 3 usefulness light transmissive materials are made; Conical shell 5 one claimed this to be spaced apart heat collector cavity at interval in outer conical shell 3 left.

Air escape valve 4 usefulness heat-insulation and heat-preservation materials are made, the lower end of air escape valve 4 pass successively outer conical shell 3 top, interior conical shell 5 the top and with they sealed attachment, 4 of air escape valves allow air run out of from bottom to top, do not allow air run from top to bottom into; If described heat collector cavity is not evacuated, then air escape valve 4 is on that section pipe between the heat collector cavity and beats some cross through hole, vacuumizes as if heat collector cavity, does not then beat described through hole.

Pipe 8 penetrate successively base plate 1, plate 7 and with they sealed attachment, connect three-position valve door 9 in pipe 8 lower ends, three-position valve door 9 have open the position for No. one, open the position for No. two, off-position (this time, open the position for No. one and open the position for No. two and all be in closed condition), the external cold water input in position is left in No. of three-position valve door 9, opens the external hot water output in position No. two of three-position valve door 9.

Overflow pipe 2 penetrate successively base plate 1, plate 7 and with they sealed attachment, connect valve 11 in its lower end.

The electric heater 6 of band temperature control function is fixed on the upper surface of plate 7, and lead 10 is the power transmission line of electric heater 6, and lead 10 slave plates 7, base plate 1 pass.

The back of the body of conical shell 3 sun one side is provided with reflector 12 outside.Certainly, if be subjected under condition restriction or the inappropriate situation reflector 12 not to be set.

When using described taper solar water heater, open valve 11 earlier, cold water is inserted No. one of three-position valve door 9 again and open the position, operation three-position valve door is opened the position 9 to No. one, and cold water enters interior conical shell 5.When water level reached the upper end (among the figure shown in the dotted line) of overflow pipe 2 and flows out through valves 11 from overflow pipe 2 is dirty, valve-off 11 immediately.If interior conical shell 5 usefulness light transmissive materials are made, sunlight sees through outer conical shell 3, interior conical shell 5 successively, directly the water in the conical shell 5 in the heating; If interior conical shell 5 usefulness Heat Conduction Materials are made, sunlight sees through conical shell 5 in the outer conical shell 3 back heating successively, and interior conical shell 5 adds hot water again.All the time according to date or on the date of severe cold, but opening electric heater 6, described spherical solar water heater just uses as water heater, but also opening electric heater 6 can prevent that described spherical solar water heater is by spalling.In the time of will using hot water, operation three-position valve door is opened the position for 9 to No. two and is promptly flowed out.

Reflector 12 can arrive outer conical shell 3 with the sunlight reflected of the positive side of outer conical shell 3 back ofs the body, increases solar energy utilization ratio.

When water in the interior conical shell 5 is heated and when expanding, the air of interior conical shell 5 inner tops can be released air escape valve 4.If described heat collector cavity is not evacuated, then heat collector cavity is heated and the air that expands, will run out of many by air escape valve 4 (usefulness be in beaten on that section pipe between the heat collector cavity some cross through hole); If described heat collector cavity vacuumizes, air escape valve 4 usefulness are in does not get through the hole on that section pipe between the heat collector cavity.Certainly, heat collector cavity vacuumizes, and described taper solar water heater heat insulating ability is fine, and heat collector cavity does not vacuumize, and runs out of many air owing to be heated, and described taper solar water heater warmer also has heat insulating ability preferably.Take out and do not vacuumize, definite according to using geography, weather, environment and user to accept the wish of price.

The effect that the utility model is useful:

1, because described taper solar water heater structure is simply compact, materials are economized, and volume little (when not establishing reflector) need not expensive vacuum tube collector, and good manufacturability need not be installed shelf, so cost is low, easy care.

2, because described taper solar water heater main body is a taper, taper make its opposing atmospheric pressure (when vacuumize in) affluence is far arranged, make its wind resistance, rain, hail ability strong, do not have vacuum tube collector and its its specific structure, there is not the problem of bursting, so the life-span is long.

3, described taper solar water heater main body is a taper, can gather sunlight greater than 180 ° of scopes (as reflector time scope be 360 °), and the solar water heater lighting scope of existing non-tracks sunlight formula is about 160 °, therefore described taper solar water heater is than the solar water heater utilization rate height of existing non-tracks sunlight formula, although collecting efficiency may be lower than vacuum tube collector under the situation not vacuumizing, the thermal-arrest benefit is not low.And the solar water heater of tracks sunlight formula, the daylighting scope is 360 °, but the cost increase is many, and power consumption, reliability reduces.So described in a word taper solar water heater has significantly high cost performance than prior solar water heater.
