Abstract
The utility model discloses a pipeline-emptying anti-freezing solar water heater, which comprises a water tank and an emptying device. The emptying device comprises a water inlet and outlet pipe, a siphon pipe and an emptying pipe. The siphon pipe passes through an inner tank from the top to the bottom. The water inlet and outlet pipe is connected with the upper part of the siphon pipe. The emptying pipe is a hollow pipe with a check valve at the upper part and an emptying valve at the lower part. The upper part of the emptying pipe is connected with the water inlet and outlet pipe; and the lower part of the emptying pipe is communicated into a chamber. The emptying pipe and the water inlet and outlet pipe are arranged in an insulation layer between the inner tank of the water tank and the shell of the water tank. The utility model overcomes the problems in the prior art, and realizes the perfect and more reasonable emptying technology and effects. And the utility model has the advantages of complete and fast emptying speed, good emptying effect, and low cost, thereby being easy to be installed and promoted.
Description
Technical field:
The utility model belongs to technical field of solar water heaters, especially relates to a kind of tube emptying antifreezing type solar water heater.
Background technology:
At present, solar water heater has obtained popularizing comprehensively, and common solar water heater needs the surface with heat-insulation layer because upper and lower conduit is exposed outside, and even so, in the winter or the north of cold, upper and lower conduit is bursting by freezing easily also.The tube emptying technical problem is all being studied by each solar water heater manufacturer, but does not obtain very good effect.Disclose a kind of " solar energy water heater pipe emptier " as State Intellectual Property Office, its emptying effect is not good enough, and because upper and lower conduit is exposed outside, than being easier to bursting by freezing, installs complicated, not easy to operate.
Summary of the invention:
The purpose of this utility model is, solves above not enoughly, and a kind of simple in structure, easy to install, emptying tube emptying antifreezing type solar water heater completely is provided.
The technical scheme that the utility model is taked is, contain water tank and emptier, water tank comprises inner bag, heat-insulation layer, crust, emptier comprises upper and lower conduit, siphon pipe and evacuated tube, siphon pipe feeds the inner bag bottom from the inner bag top, upper and lower conduit links to each other with siphonal top, evacuated tube is that the hollow pipe that check-valves, bottom are equipped with exhaust-valve is equipped with on top, evacuated tube top connects upper and lower conduit, bottom and feeds indoorly, and evacuated tube and upper and lower conduit are installed in the heat-insulation layer between inner water tank and the crust.
The beneficial effects of the utility model are, overcome the technical difficult problem of existing emptying, realized improving more rational emptying technology and effect, intestine evacuation velocity is fast and thorough, good freezing protection effect, because evacuated tube and upper and lower conduit are coated in the heat-insulation layer between inner water tank and the crust, become the part of solar water heater, structural integrity, easy to install, and with low cost, be easy to promote.
Description of drawings:
Fig. 1 is the structural representation of the utility model tube emptying antifreezing type solar water heater;
Fig. 2 is the structural representation of the another kind of embodiment of the utility model tube emptying antifreezing type solar water heater.
The specific embodiment:
From the structural representation of the utility model tube emptying antifreezing type solar water heater shown in Figure 1 as can be seen, the utility model contains water tank and emptier, water tank comprises inner bag 7, heat-insulation layer 6, crust 5 three parts, on water tank, have steam vent 4 and backwater hole 3, emptier comprises upper and lower conduit 11, siphon pipe 10 and evacuated tube 2, inner water tank 7 tops are towards circular hole, siphon pipe 10 feeds inner bag 7 bottoms in circular hole, be used for suction and add water, threeway tube coupling 9 is equipped with on the top of siphon pipe 10, is connected with evacuated tube 2 with the upper and lower conduit 11 of threeway tube coupling 9 with the right and left.Evacuated tube 2 is hollow pipes, and it is indoor that the bottom feeds, and in the top and upper and lower conduit 11 junctions of evacuated tube 2 check-valves 8 is housed, and in the lower end of evacuated tube 2 exhaust-valve 1 is housed, and exhaust-valve 1 is installed in indoor.Evacuated tube 2 and upper and lower conduit 11 are installed in the heat-insulation layer 6 between inner water tank 7 and the crust 5, evacuated tube 2 is passed by the water tank bottom along the heat-insulation layer of top and the heat-insulation layer in left side, upper and lower conduit 11 is passed by the water tank bottom along the heat-insulation layer of top and the heat-insulation layer on right side, upper and lower conduit 11 is connected on indoor running water pipe 13 and the hot-water line 15, running water pipe 13 is connected by running water valve 12 with upper and lower conduit 11, and hot-water line 15 is connected by hot-water valve 4 with upper and lower conduit 11.
From the structural representation of the another kind of embodiment of the utility model tube emptying antifreezing type solar water heater shown in Figure 2 as can be seen, evacuated tube 2 and upper and lower conduit 11 are passed by the water tank bottom downwards along the back heat-insulation layer.Owing to have solar energy heat collection pipe on the heat-insulation layer in water tank the place ahead, so evacuated tube 2 and upper and lower conduit 11 pass along the heat-insulation layer of water tank back.
Operation principle of the present utility model: 1. add water: close hot-water valve 14, open running water valve 12, when running water flows forward, check-valves 8 cuts out, running water flows to water tank by upper and lower conduit 11 and siphon pipe 10 endlessly, after water tank water was full, backwater hole 3 backwater were closed running water immediately.Also available instrument control automatically goes up water.2. emptying: open exhaust-valve 1 and hot-water valve 14, the water in the upper and lower conduit 11 can all be drained, and closes exhaust-valve 1 and hot-water valve 14 then.3. use hot water: close exhaust-valve 1, open running water valve 12 up and down water pipe 11 add water several seconds, close running water valve 12 immediately, open hot-water valve 14 then, hot water will flow out.This process is to utilize siphon principle to finish.
The outer pipeline of water tank can be incubated a little or not be incubated all can, subzero 30 degree can freezing pipeline because evacuated tube 2 and upper and lower conduit 11 are placed on heat-insulation layer 6 inside, tube emptying is to the whole emptyings of water tank exterior line from the water tank internal duct.Spring, summer, autumn can be closed emptying pipe, by the common water heater procedure operation.
