Abstract
The utility model discloses an automatic defrosting solar water heater for a low sunshine area. The automatic defrosting solar water heater comprises a thermal-collecting tube, a water tank, a water outlet tube and a power supply, wherein an electric heating wire is spirally wound on the outer circumferential surface of the water outlet tube outside a water outlet of the water tank; the electric heating wire is connected with a storage battery; a temperature sensor which controls the electric heating wire to work is also arranged on the water outlet tube; and a heat insulation layer covers the electric heating wire. After the device is adopted, when the weather temperature is lower than zero DEG C, a loop is switched on by the temperature sensor, and the electric heating wire works; when the temperature is risen to 4 DEG C, the loop is switched off by the temperature sensor, and the electric heating wire stops working; and in such a way, even in frosty whether in the southwest, a solar water heater can also work normally, and can neither be frosted nor blocked. The automatic defrosting solar water heater for the low sunshine area is simple in structure, low in cost and easy to install, and works stably and reliably.
Description
Technical field
The utility model relates to a kind of solar water heater, particularly a kind of low sunshine area automatic defrosting formula solar water heater.
Background technology
The world today, the energy is more and more in short supply, and solar water heater receives liking of people day by day owing to can effectively utilize the natural green energy.But be easy to generate frost the winter in China southwest at low sunshine especially, and at this weather, the outer part of solar water heater outlet pipe outlet is prone to freeze, and causes emitting water; In case this phenomenon occurs, need to melt away this position water pipe heating icing.
By on can know that automatic defrosting formula solar water heater in area on reality is used, obviously had defective and existed, and remain to be improved above-mentioned existing low sunshine.
Thus, the improving of the above-mentioned defective of the utility model thoughts is that the spy concentrates on studies and cooperates repetition test, proposes a kind of reasonable in design and effectively improve the utility model of above-mentioned defective finally.
Summary of the invention
To the weak point of prior art, the utility model aims to provide one and hangs down area automatic defrosting formula solar water heater at sunshine, does not freeze to guarantee the part of this water heater outside the outlet of frost sky water pipe, can normally use.
For solving the problems of the technologies described above; The technical scheme that the utility model adopts: a kind of low sunshine area automatic defrosting formula solar water heater; Comprise thermal-collecting tube, water tank, outlet pipe and power supply, spiral twines heating wire on the outlet pipe outer circumference surface outside water outlet of water tank, and heating wire is connected with power supply; On outlet pipe, also be provided with the temperature sensor of control heating wire work, outside said heating wire, cover one deck heat-insulation layer again.
After adopting said apparatus, when the same day, the temperature degree was lower than zero degree, temperature sensor was connected the loop; Heating wire work is when temperature rises to 4 when spending, the temperature sensor cutoff circuit; Heating wire quits work; Even like this at the frosty weather on southwest ground, solar water heater also can operate as normal, can not take place to stop up the outlet pipe phenomenon because of frost.
The utility model is simple in structure, and cost is low, is prone to install, and working stability is reliable.
Description of drawings
Fig. 1 is the utility model structural representation;
In the accompanying drawing: 1 water tank, 2 thermal-collecting tubes, 3 outlet pipes, 4 heating wires, 5 heat-insulation layers.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1; The utility model comprises thermal-collecting tube 2, water tank 1, outlet pipe 3 and power supply; Spiral twines heating wire 4 on outlet pipe 3 outer circumference surfaces outside water tank 1 delivery port, and heating wire 4 is connected with the power supply (not shown), on outlet pipe 3, also is provided with the temperature sensor (not shown) of control heating wire 4 work; Outside said heating wire 4, cover one deck heat-insulation layer 5 again, heat-insulation layer 5 is selected refractory fibre for use.
Because the water tank heat preserving of solar water heater is effective; Water temperature in the frost sky in the southwest, water tank can reach degree more than 10, yet the temperature of the outlet pipe 3 outside water tank 1 delivery port is but near outdoor temperature; Stable be lower than when subzero when outdoor; The outer outlet pipe 3 of delivery port is prone to congeal, and causes water heater can't emit hot water, and the utility model efficiently solves this problem; And institute's consuming electric power is few, and required power supply can be used normal domestic use power supply or battery.
