When described connection heat collector pipeline inserts and pick out described inner water tank, all adopt to be tightly connected.
Described press-bearing water tank also is provided with electric heater unit.
The utility model adopts the non-pressure-bearing solar heat collector of all-glass vacuum tube type, wall-hanging installation, and press-bearing water tank is installed on the top of the non-pressure-bearing solar heat collector of all-glass vacuum tube type.Water in the all-glass vacuum tube absorbs heat and by circulation the coolant-temperature gage in the inner water tank is improved under shining upon; Pass to the water in the heat collector pipeline of being connected that links to each other with press-bearing water tank then, connect the Natural Circulation of water by cold water sinking hot water come-up in the heat collector pipeline, the coolant-temperature gage in the press-bearing water tank is improved.
The utility model is to guarantee still have good serviceability under the big situation of overcast and rainy or harsh climate or water consumption, and electric heater unit can be installed in press-bearing water tank, heats to improve water temperature so that start heater when being necessary automatically.In the utility model, the bottom of press-bearing water tank also is provided with sewage draining exit, can clear up blowdown to prevent fouling to inner water tank in case of necessity.
This wall-hanging solar water heater has been realized non-pressure-bearing thermal-arrest, bearing operation, and compared with prior art structure is more reasonable, and production cost can significantly reduce, and helps applying.
Description of drawings
Accompanying drawing is a kind of embodiment structural representation of the utility model.
The specific embodiment
Embodiment 1:
As shown in drawings, this non-pressure-bearing heat collector connects the wall-hanging solar water heater of press-bearing water tank, comprises the non-pressure-bearing solar heat collector 1 of all-glass vacuum tube type, press-bearing water tank 2 and is connected heat collector pipeline 3; Press-bearing water tank 2 is installed on the top of the non-pressure-bearing solar heat collector 1 of all-glass vacuum tube type; The non-pressure-bearing solar heat collector 1 of all-glass vacuum tube type comprises all-glass vacuum tube 4 and header 5, and header 5 is made up of the heat-insulation layer 8 between outer case 6, inner water tank 7 and outer case 6 and the inner water tank 7; The top of header 5 is provided with automatic water supply tank 13, and water supply tank 13 connects tap water supply pipe 15, and the top of water supply tank 13 is provided with the hole 14 that communicates with atmosphere; The bottom of press-bearing water tank 2 be provided with water inlet pipe 9 and outlet pipe 10 and be connected delivery port 11 and the water inlet 12 that heat collector pipeline 3 links to each other, the top of outlet pipe 10 sensible press-bearing water tanks 2 wherein, the middle and upper part of water inlet 12 sensible press-bearing water tanks 2; Connect heat collector pipeline 3 and pick out, enter heat-insulation layer 8 to place, nearly bottom from the top of header 5 and enter inner water tank 7, and lead to the top and pick out header 5, link to each other with water inlet 12 then through heat-insulation layer 8 from delivery port 11.When connecting 3 accesses of heat collector pipeline and picking out inner water tank, all adopt to be tightly connected.Bottom at press-bearing water tank 2 also is provided with sewage draining exit 16, can clear up blowdown to prevent fouling to inner water tank 7 in case of necessity.
In the present embodiment, the water in the non-pressure-bearing solar heat collector 1 of all-glass vacuum tube type is heat medium, Natural Circulation; The effect of overflow can be played in the set hole that communicates with atmosphere 14, the top of water supply tank 13; And when water shortage, then replenish running water by tap water supply pipe 15.Press-bearing water tank 2 be connected heat collector pipeline 3 and link to each other, water in the press-bearing water tank 2 utilizes cold water sinking hot water come-up principle to form Natural Circulation through connecting heat collector pipeline 3, obtain heat from the inner water tank 7 of the non-pressure-bearing solar heat collector 1 of all-glass vacuum tube type, thereby improve the temperature of the water in the press-bearing water tank 2; Delivery port 11 is located at the bottom, thereby the temperature always that flows out is than the water at the end, and water inlet 12 has stretched into the middle and upper part of press-bearing water tank 2, thereby has obtained that the higher water of temperature of certain heat always enters in the middle and upper part.When need using hot water be bearing operation, and running water enters from water inlet pipe 9, and hot water flows out from outlet pipe 10, because the mouth of pipe of outlet pipe 10 is on the top of press-bearing water tank 2, thereby the hot water always that flows out of outlet pipe 10.
Embodiment 2:
Electric heater unit is installed in press-bearing water tank, meet overcast and rainy or harsh climate or water consumption big, cause when water temperature is on the low side in the press-bearing water tank, can start heating automatically to improve water temperature.
All the other are identical with embodiment 1.
