The specific embodiment

Label declaration: 1 expression upper and lower conduit; 2 expression switch control units; 3 expression exhaust-valves; 4 expression inlet channels; 5 expression time-delay exhaust-valves; The 6 emptying switches of expression; 7 expression water intake valves; 8 expression water level detecting unit; 9 expression water compensating valves; 10 expression filling pipe ends; The lower mouth of a river of 11 expressions; 12 expression water inlets; 13 express the mouth of a river; 14 expression storage tanks.

the utility model embodiment, with reference to Fig. 1, Fig. 2, Fig. 3, solar water heater emptier in figure, comprise upper and lower conduit 1, water level detecting unit 8, holding wire, switch control unit 2, water intake valve 7, water compensating valve 9, switch control unit 2 comprises relay switch and one group of delay switch, junction at upper and lower conduit 1 and solar water heater storage water tank 14 arranges exhaust-valve 3, the other end at upper and lower conduit 1 arranges time-delay exhaust-valve 5, the water intake valve 7 emptying switch 6 that is connected, the relay switch of switch control unit 2 is electrically connected to respectively water level detecting unit 8 by holding wire, exhaust-valve 3 and emptying switch 6, delay switch is electrically connected to time-delay exhaust-valve 5.Exhaust-valve 3 comprises magnetic valve and the inlet channel 4 that is provided with filling pipe end 10, the lower mouth of a river 11, and inlet channel 4 is communicated with the lower mouth of a river 11, and the lower mouth of a river 11 is communicated with upper and lower conduit 1, and filling pipe end 10 is communicated with storage tank 14; Time-delay exhaust-valve 5 is for being provided with the magnetic valve of water inlet 12 and delivery port 13, and water inlet 12 is communicated with upper and lower conduit 1.

The user uses the course of work of solar water heater.Before use, the filling pipe end 10 of exhaust-valve 3 is in normally off, and time-delay exhaust-valve 5 water inlets 11 are in normally off, and water intake valve 7 is in normally off, and water compensating valve 9 is in normally off.The user is the hot water that uses water intake valve 7 to flow out.When the user uses, open water intake valve 7, due to water intake valve 7 and emptying switch 6 interlocks, emptying switch 6 also is opened simultaneously.Emptying switch 6 is electrically connected to switch control unit 2, and switch control unit 2 is electrically connected to by holding wire and controls opening and closure of exhaust-valve 3, time-delay exhaust-valve 5 and water compensating valve 9.After signal that emptying switch 6 is opened passes to switch control unit 2, switch control unit 2 is just controlled exhaust-valve 3 and is opened filling pipe end 10, closes inlet channel 4, at this moment, the hot water in storage tank 14 flows into upper and lower conduit 1 by filling pipe end 10, the lower mouth of a river 11, flows out by water intake valve 7.

After the user finishes using, close water intake valve 7, emptying switch 6 is closed in interlock, and the signal that emptying switch 6 cuts out passes to switch control unit 2, and switch control unit 2 control exhaust-valve 3 filling pipe ends 10 are closed, inlet channel 4 is opened, delayed time, and exhaust-valve 5 water inlets 12 are opened.At this moment, hot water in storage tank 14 no longer enters upper and lower conduit 1, inlet channel 4 is introduced upper and lower conduit 1 by the lower mouth of a river 11 with the air in the external world, and the water in upper and lower conduit 1 is discharged by time-delay exhaust-valve 5 water inlets 12 and delivery port 13 under the effect of external atmosphere pressure and self gravitation.The delay time that time-delay exhaust-valve 5 is set according to delay switch, the water inlet 11 of autoshutdown time-delay valve 5.The time delay that time-delay exhaust-valve 5 water inlets 12 are set according to delay switch, realize autoshutdown.The user can according to managing up and down what of 1 water-holding quantity, be regulated the water discharge time of upper and lower conduit 1 by delay switch.

When water level detecting unit 8 detects storage tank 14 and needs moisturizing, just pass to switch control unit 2 moisturizing signals, switch control unit 2 is controlled exhaust-valves 3 and is opened filling pipe end 10, closes inlet channel 4, opens water compensating valve 9.Cold water enters upper and lower conduit 1 by water compensating valve 9, and the filling pipe end 10 by exhaust-valve 3 enters storage tank 14; After complete to storage tank 1 moisturizing, switch control unit 2 transmission of signals are given in water level detecting unit 8, switch control unit 2 is controlled the water inlet 12 that water compensating valve 9 is closed, exhaust-valve 3 filling pipe ends 10 are closed, exhaust-valve 5 is opened, delayed time to inlet channel 4 and is opened, and begins emptying upper and lower conduit 1.

The utility model adopts the constructional devices such as exhaust-valve, time-delay exhaust-valve, emptying switch, switch control unit, when having realized that solar water heater does not use, remain that upper and lower conduit is in the empty pipe condition without water, effectively anti-antipriming pipe is damaged by bursting by freezing because of water; Avoid the water resource waste that causes because of the cold water of discharging in upper and lower conduit, improved the hot service efficiency of solar energy.
