Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of exhaust-valve;
Fig. 3 is the structural representation that postpones exhaust-valve.
The specific embodiment
Label declaration: 1 means upper and lower conduit; 2 mean switch control unit; 3 mean exhaust-valve; 4 mean inlet channel; 5 mean the time delay exhaust-valve; 6 mean emptying switch; 7 mean water intake valve; 8 mean the water level detecting unit; 9 mean water compensating valve; 10 mean filling pipe end; 11 mean the lower mouth of a river; 12 mean water inlet; 13 express the mouth of a river; 14 mean storage tank.
The present invention executes example, 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, in upper and lower conduit 1 and the junction of solar water heater storage water tank 14, exhaust-valve 3 is set, 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 11，Xia mouth of a river, the lower mouth of a river 11 and 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 and controls opening and closure of exhaust-valve 3, time delay exhaust-valve 5 and water compensating valve 9 by holding wire.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, now, 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, by water intake valve 7, flows out.
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, time delay exhaust-valve 5 water inlets 12 are opened.Now, 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 by extraneous air, and the water in upper and lower conduit 1, under the effect of external atmosphere pressure and self gravitation, is discharged by time delay exhaust-valve 5 water inlets 12 and delivery port 13.Time delay exhaust-valve 5, according to the delay time of delay switch setting, is closed the water inlet 11 of time-delay valve 5 automatically.The time delay that time delay exhaust-valve 5 water inlets 12 are set according to delay switch, realize automatically closing.The user can according to manage up and down 1 water-holding quantity the number, 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 to storage tank 1 moisturizing, switch control unit 2 transmission of signals are given in water level detecting unit 8, switch control unit 2 control water compensating valves 9 are closed, exhaust-valve 3 filling pipe ends 10 are closed, inlet channel 4 is opened, the water inlet 12 of time delay exhaust-valve 5 is opened, and starts emptying upper and lower conduit 1.
The present invention adopts the constructional devices such as exhaust-valve, time delay exhaust-valve, emptying switch, switch control unit, while having realized that solar water heater is not used, remains that upper and lower conduit is in the empty pipe condition without water, and effectively anti-antipriming pipe is damaged by bursting by freezing because of water; Avoid the water resource waste caused because of the cold water in the discharge upper and lower conduit, improved the hot service efficiency of solar energy.
