Show like Fig. 1.Inner casing 3, shell 5 are spherical shell or ellipsoid shelly; Inner casing 3 usefulness light transmissive materials or Heat Conduction Material are made; Make with Heat Conduction Material; Being coated with existing high solar absorptance at its outer surface has the selective coating material of low radiance again or paints dark color (blackish green, be coated with coating such as dark, indigo plant); Make with light transmissive material, within it surfaces coated selective coating material or paint dark color; Shell 5 usefulness light transmissive materials are made; Shell 5 leaves inner casing 3 one at interval, and this forms a cavity at interval; Shell 5 is fixed in base plate 1.

Air escape valve 6 is used the heat-insulation and heat-preservation material, the lower end of air escape valve 6 pass successively shell 5 top, inner casing 3 the top and with they sealed attachment, 6 of air escape valves let air run out of from bottom to top, do not allow air run from top to bottom into; When said cavity was not evacuated, air escape valve 6 is on that section pipe between the said cavity beat some cross through hole; Said cavity vacuumizes, and does not then beat said cross through hole.

The lower side that the upper end of the upper end of a pipe 8, No. two pipes 2, the upper end of liquid level sensor 4 all penetrate shell 5, inner casing 3 successively stretches into inner casing 3; 8, No. two pipes 2 of a pipe, liquid level sensor 4 and shell 5 and inner casing 3 sealed attachment, the upper end of liquid level sensor 4 is higher than the upper end of No. two pipes 2; Connect valve 9, No. two 11, numbers valves of valve, 9 external cold water inputs respectively in 8, No. two pipes of a pipe, 2 lower ends, No. two valve 11 external hot water outputs.

The electric heater 7 of band temperature control function is fixed in the inner casing 3, and lead 10 is the power transmission line of electric heater 7, and lead 10 passes from inner casing 3, shell 5.

Back of the body sun one side at shell 5 is provided with reflector 12.Certainly, if receive under condition restriction or the inappropriate situation reflector 12 not to be set.

When using the spherical solar water heater of said no vacuum tube, no adiabator layer, no shelf, make a call to valve 9 No. one earlier, cold water is injected inner casing 3.When water level reaches the upper end (among the figure shown in the dotted line) of liquid level sensor 4, close valve 9 immediately No. one.If inner casing 3 usefulness light transmissive materials are made, sunlight sees through shell 5, inner casing 3 successively, directly heats the water in the inner casing 3; If inner casing 3 usefulness Heat Conduction Materials are made, sunlight sees through shell 5 back heating inner casings 3 successively, and inner casing 3 adds hot water again.All the time according to date or on date of severe cold; But opening electric heater 7; The spherical solar water heater of said no vacuum tube, no adiabator layer, no shelf just uses as electric heater, but also opening electric heater 7 can prevent that the spherical solar water heater of said no vacuum tube, no adiabator layer, no shelf from being split by frost heave.When using hot water, open valve 11 No. two.

Reflector 12 can arrive shell 5 with the sunlight reflected of the positive side of shell 5 back ofs the body, increases solar energy utilization ratio.

When water in the inner casing 3 is heated and when expanding, can the air of inner casing 3 inner tops be released air escape valve 6.If said cavity is not evacuated, then cavity is heated and the air that expands, will run out of many through air escape valve 6 (usefulness be in beaten on that section pipe between the cavity some cross through hole); If said cavity vacuumizes, air escape valve 6 usefulness are in does not get through the hole on that section pipe between the cavity.Certainly; Cavity vacuumizes; The spherical solar water heater heat insulating ability of said no vacuum tube, no adiabator layer, no shelf is fine; Cavity does not vacuumize, and runs out of many air owing to be heated, and the spherical solar water heater warmer of said no vacuum tube, no adiabator layer, no shelf 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 the spherical solar water heater of said no vacuum tube, no adiabator layer, no shelf is simple and compact for structure, materials province, the vacuum tube collector that volume little (when not establishing reflector) need not costliness; Without adiabator layer, good manufacturability need not be installed shelf; Therefore cost is low, easy care.

2, because the spherical solar water heater main body of said no vacuum tube, no adiabator layer, no shelf is spherical; Spherical its opposing atmospheric pressure (when vacuumizing) that makes far has affluence; Make its wind resistance, rain, hail ability strong; Do not have vacuum tube collector and its its specific structure, do not have the problem of bursting, so the life-span is long.
