Form below in conjunction with two version and the action principles of driving heat build-up of accompanying drawing 2 summaries:

As shown in Figure 2:

One, the inner water tank with a solar energy divides two sections making, and the A section is the water tank that (70～90) rise, and the B section is the water tank that (90-200) rises.The A water tank is that electric heater water tank and solar water container are shared, is referred to as " two driving "; The B water tank is pure solar water container; A, B two water tanks are referred to as " two-region ".In operation was used, the A water tank was the high-temperature region, and the B water tank is warm area in low.A, B two water tanks are packed the shell of an integral body into when carrying out thermal insulation foaming, and the foam with 20mm between A, the B case is isolated, and prevents A, the intermetallic heat conduction of B case as shown in the figure.

Two, the aquaporin connected system and the effect of A, B water tank.The A case is provided with hot water outlet pipe C, and its setting height(from bottom) is 1/2nd of an A case diameter, is provided with blast pipe D and temperature, level sensor E are installed, and electrical auxiliary heater N (1.5KW) is installed.The B case is provided with cold water inlet F, and when the water inlet electromagnetism was closed, the B water tank was in full closeding state.The connection of A, B water tank is combined into the water channel linker with nonmetallic heatproof pipe fitting, and its requirement makes the upper water of B water tank inject the bottom of water tank.The welding shutter makes the water at low temperature that enters all in the case bottom in the water inlet bucket of A, B water tank, thereby the high-temperature water in the case is upwards pushed up.

Three, control system: form a cover solar heat water control system by water temperature, water level controller and water level, water temperature inductor, electric heater, last water solenoid valve switch (or force (forcing) pump), the adjusting of controller requires: the holding temperature adjustable range is at 45～80 ℃: when water level descends 2/5ths water levels for the A water tank, postpone to add running water toward the B water tank after 8 minutes, treat that the A water tank stops to go up water when filling 5H.

Four, space can two drive the operation logic situation of heat build-up series solar water.

1, the operation logic of rainy weather and situation: heat the first time after installing, the water temperature that the A water tank is 70 liters is also below 20 ℃ the time, heating needs 40 minutes～1 hour approximately to 70 ℃, when first member used 70 liters hot water to drop to 4H, the Shi Jiashui that continues postponed the water temperature variation that water does not influence shower in 8 minutes; The water of B case enters the bottom of A case after 8 minutes, and bath water is at the middle part, and the water temperature that does not also influence shower changes.The high-temperature water (actual 48 ℃ water is about 60 liters) that first member takes a shower and spends 30 liters 70 ℃ approximately, add to the 5H water (70 liters) of A water tank this moment, and its water temperature is calculated as 50 ℃ by heat equivalent; Controller starts electrical heating when temperature drops to 65 ℃, can go back up to 70 ℃ with 20 minutes approximately, so operation, and after all kinsfolks had taken a shower, when the water of A water tank heated with 20 minutes, the hot water that just has 70 liters used at any time.If need not to use hot water next day, also needn't worry waste, because water heater has good insulation effect, still can keep more than 65 ℃ to second day water temperature in evening, first member's water need not to drop into electrical heating.So operation, even two heat build-up solar water heater that drives uses at rainy weather continuously, also can saves energy, and guarantee had hot water to use at any time in 24 hours.

2, two operation logic and situations of driving heat build-up series solar water heater fine day.Fine preferably the insulation setting valve of controller is adjusted to 50 ℃, when the water temperature of fine B water tank during at 60 ℃, the A water tank since former water temperature more than 50 ℃, so by the same day sun the thermal-arrest water temperature must be higher than the water temperature of B water tank, be about about 90 ℃.When using the summation water yield of solar energy A, B water tank, the water temperature of A water tank is about 60 ℃, the water at low temperature that adds the B water tank also can be utilized the high-temperature water in A, the B water tank vacuum tube last part, so just enlarged the water capacity of using of solar water heater, and the water that can keep the A water tank does not need electrical heating more than 50 ℃.
