The utility model has convenient use.
Description
The utility model belongs to the solar electric water heater of household electrical appliance.
Listing now as the solar water heater of shower two kinds of charged heating and not charged heating are arranged, but cylindrical glass tube water storage, thermal-arrest that their heat collector great majority adopt interlayer to find time, superconducting pipe being placed in the glass tube of also having absorbed heat and transferring heat energy, there is the shortcoming that glassware is frangible and collector area is less in this kind mode, and they generally all do not have the indication of temperature and water level.
The purpose of this utility model: provide a kind of adopt strengthen collector area, improve collecting efficiency, non-damageable and have a profiled metal thermal-collecting tube solar electric water heater of temperature, water level indication.
The purpose of this utility model is to realize like this, the cylindrical glass tube that heat collector is found time by traditional interlayer, change the corrosion resistant aluminum alloy special pipe of the cylindrical tube two side band wings into, outer black coated is placed in the shell, front cover upper glass and integrated reinforcing, with heat collector two ends sealing insulation, improve collecting efficiency to increase collector area, heat collector converts solar energy to heat energy rises water temperature, the water of heat collector is communicated with the water of water storage tank and forms Natural Circulation, place electric heating tube in the middle of the water tank bottom, water inlet pipe and water outlet pipe, overflow pipe and water level, cooling-water temperature sensor etc., carry out electrical heating when needed, and water level arranged, the water temperature indication, water temperature is controlled when carrying out electrical heating.
Owing to adopt such scheme, the utility model is bigger than the solar electric water heater collector area of existing listing, collecting efficiency is high, and is sturdy and durable, and it is easy to use to be provided with various indications.
Below in conjunction with drawings and Examples, the utility model is further specified.
Fig. 1 is the utility model structure connection diagram, and middle heat collector shifts out.
Fig. 2 is the axis projection figure of the utility model heat collector.
Fig. 3 is the utility model electrical schematic diagram.
Among the figure in 1. water storage tanks, 2. water low sensors, 3. water water-bed sensor 15. overflow pipes of level sensor 4. water high position sensor 5. shell of water storage tanks 6. water storage tank inner bags 7. heat-insulation layers, 8. cooling-water temperature sensors, 9. electric heating tubes, 10. water power assemblies, 11. shelves, 12. profiled metal thermal-collecting tubes, 13. heat collectors 14. 16. water inlet pipe and water outlet pipes 17. bundle conductors 18. control indication boxes 19. buzzers 20. running water valves 21. about water valve 22. spray water valves 23. spray throwers 24. glass 25. heat collector shells 26. power transformers 27. full-bridge rectifiers.
After connecting the water source, open water valve (20) and water valve (21) from the beginning up and down, closing spray water valve (22) cold water enters from the direction of arrow and flows through up and down water valve (21) water inlet pipe and water outlet pipe (16) and inject in the water storage tank inner bag (6), and flow in each heat collector (13), after water level surpasses water high position sensor (4), water valve (20) water then will overflow from overflow pipe (15) as not closing from the beginning.
When solar radiation arrives each heat collector (13), because its surface is the black coated, it is close to 100% with sunlight and is converted to heat energy, and conduct to the water in the pipe through the corrosion resistant aluminum alloy pipe and to make water temperature rising, water temperature rising back water density diminishes and rises to the water storage tank inner bag (6) that is communicated with it, cold water but constantly replenishes and flow in the heat collector simultaneously, forms Natural Circulation.In order to increase daylighting area, heat collector is made profiled metal thermal-collecting tube (12), promptly two sides are stretched out two wings outside circular aluminum pipe, the sunlight that receives on two wings becomes thermal energy conduction earlier and conducts feedwater again to pipe, outside profiled metal thermal-collecting tube (12), put shell (25) front cover upper glass (24) and integrated reinforcing in order to improve the thermal efficiency, simultaneously heat collector shell two ends are sealed, do not allow the mobile heat energy that reduces on the thermal-collecting tube of air from air, run off, profiled metal thermal-collecting tube (12) one ends sealing water storage, other end cylindrical part is long to be inserted in the water storage tank inner bag (6).Water temperature in the water storage tank (1) constantly rises under solar radiation, wraps heat-insulation layer (7) and water storage tank shell (5) with insulation outside water storage tank inner bag (6).In order to make water Natural Circulation normally, need water storage tank (1) is placed on the shelf (11), the height of shelf should make heat collector (13) to horizontal plane shape in an angle, the size of angle during with use residing latitude relevant, latitude high angle more is big more, generally gets about 30 °~40 ° to get final product.
Arrived the winter of severe cold or run into sleety weather, when the irradiation of sunlight can not make water temperature reach serviceability temperature, then can connect the power supply electricity consumption and do auxiliary heating.Toggle switch K
