Description

The solar water heater defroster

The utility model belongs to technical field of solar water heaters, the defroster of the upper and lower waterpipe of particularly a kind of solar water heater.

At present, the subject matter that solar water heater in use exists be about, waterpipe freezes by low the influence easily of temperature, even with frost crack pipe, thereby bring use inconvenience winter, and limited at extremely frigid zones greatly and applied.Be head it off, the employing Electric heating is arranged, the thick insulation layer of adding mode is arranged, technology such as tube emptying mode are arranged.Mode of heating had both been wasted electric energy, complex structure again.Add the thick insulation layer mode and can only solve effectively use under the low cold temperature, then can not effectively use when reaching below-15 ℃ for extremely frigid zones temperature.The tube emptying mode is most advanced and effective and efficient manner, but the existing structure complexity is used inconvenient.

The purpose of this utility model is to have deficiency and design a kind of novel solar water heater defroster at prior art.Advantages such as this defroster has simple in structure, and cost is low, does not waste electric energy, and is easy to use can effectively solve the difficult problem that the low upper and lower conduit road of temperature freezes.

The feature of this solar water heater defroster is that it is made up of upper and lower conduit road and electromagnetic valve two parts, the upper and lower conduit road is provided with air inlet pipe, electromagnetic valve is made of parts such as valve rod, permanent magnet, spool, electromagnet and change-over switch, housings, electromagnet is divided into electromagnet and lower electromagnet two parts, spool is packed in stem lower portion, permanent magnet be contained in valve rod top and place electromagnet and lower electromagnet between, valve rod and spool are contained in the upper and lower conduit road, and valve rod, permanent magnet, electromagnet and parts are packed in the housing.The upper and lower conduit road is the intake-discharge pipe road of solar water heater water tank, communicate with indoor running water pipe during water inlet, then running water enters in the water tank by electromagnetic valve through this upper and lower conduit road, and water or the water in the upper and lower conduit road during following water in the water tank are discharged from the indoor drainage mouth through this pipeline.Air inlet pipe is for the ponding of getting rid of efficiently and effectively in the upper and lower conduit road is provided with, and the air inlet on air inlet pipe top should be higher than peak level in the water tank, in case running water overflows from air inlet pipe top during water inlet.Electromagnetic valve is the core of present technique, and it is by advancing drainage switch control.Describe in detail below in conjunction with accompanying drawing.

Fig. 1 is the main TV structure schematic diagram of the utility model solar water heater defroster.

Fig. 2 is installed in schematic diagram on the solar water heater for the solar water heater defroster.

Among Fig. 1, Fig. 2: 1. running water valve, its directly water inlet in water tank (11); 2. scupper valve, it is located on the upper and lower conduit road (4), plays the interior ponding of water or upper and lower conduit road (4) in the eliminating water tank (11); 3. air inlet pipe, it is located on the upper and lower conduit road (4), in the use after water is filled with in the water tank (11), then close running water valve (1) earlier, the spool (5) of electromagnetic valve is closed downwards, the water in the water tank (11) then can not flow out through upper and lower conduit road (4) again, opens scupper valve (2) this moment, the air of outside is very fast to enter into the ponding that excludes efficiently and effectively in the upper and lower conduit road (4) in the upper and lower conduit road (4), so effectively preventing freezing or freezing pipeline from air inlet pipe (3); 4. upper and lower conduit road; 5. spool is used the rubber type of material manufacturing, plays the valve closing effect; 6. housing plays each the parts effect of Motionless electromagnetic valve; 7. permanent magnet, it is made with permanent-magnet material; 8. go up electromagnet, the energising back is with regard to carrying magnetic, and during use, when the same electromagnet of permanent magnet (7) (8) contacted, then permanent magnet (7) meeting drive valve rod (9) and spool (5) moved up, and running water just can flow to water tank (11) along upper and lower conduit road (4); 9. valve rod; 10. lower electromagnet, energising back carrying magnetic, in the middle of the use, when the same lower electromagnet of permanent magnet (7) (10) contacted, then permanent magnet (7) meeting drive valve rod (9) and spool (5) moved down also valve-off, and the water in the water tank (11) just can not flow out through upper and lower conduit road (4), open scupper valve (2) this moment, the ponding in the upper and lower conduit road of just draining, last electromagnet (8) and lower electromagnet (10) are by change-over switch control, and change-over switch can be contained in indoor; 11. water tank, it is the water tank of solar water heater; 12. overflow pipe plays and observes or the effect of control solar water heater water level; 13. the solar water heater defroster, it is installed on the water tank (11) of solar water heater.The electromagnetic valve power supply can adopt Dc low voltage power supply.

This defroster has simple in structure, and cost is low, and is easy to use, do not waste advantages such as electric energy, can effectively solve the difficult problem that the low upper and lower conduit road of temperature freezes.

Fig. 1, Fig. 2 can be used as an example structure schematic diagram of the present utility model.Explanation as previously mentioned among the figure.
