Abstract

The utility model discloses a domestic solar water heater, comprising a water tank, heat collecting pipes, and two water delivery pipes. The water tank is provided with a cold water inlet pipe and a hot water outlet pipe. The essential technical characteristic is that the bottom of the water tank is provided with the two water delivery pipes, and the heat collecting pipes which are communicated with the two water delivery pipes are arranged between the two water delivery pipes; the heat collecting pipes are connected with a heat collector; the heat collector can be rotated around the heat collecting pipe to fit the adjustment of the direction of light; the heat collecting pipes are vertically arranged from top to bottom. The water delivery pipes can be used as the supporting frame of the domestic solar water heater, and the tail ends of the supporting frame can be provided with supporting legs. The domestic solar water heater can be installed in a suspended type or in an upright type. The utility model has the advantages of low cost, good heat collecting effect, and convenient operation; moreover, the domestic solar water heater can fit many positions at the time of installation.

Description

The domestic solar water heater

The utility model relates to a kind of solar water heater.

Present employed thermal efficiency ratio higher solar energy water heater, primary structure comprises attemperater, heat collector, heat collector mainly adopt vacuum heat collection pipe, because its energy-conservation favor that is subjected to people day by day.But its cost and price be than higher, and be to be suitable for being installed in roof, causes certain inconvenience to application, as the hydraulic pressure problem.

It is low that the purpose of this utility model provides a kind of cost, and Heat-collecting effect is good, and the installation site is the domestic solar water heater flexibly.

Domestic solar water heater of the present utility model, comprise water tank, thermal-collecting tube, water-supply-pipe, have cold water inlet and hot water outlet pipe on the water tank, its major technique characteristics are that water tank bottom has two water-supply-pipes, have between two water-supply-pipes to be attached thereto logical thermal-collecting tube, connect a heat collector on the thermal-collecting tube.

The above heat collector can rotate around thermal-collecting tube, adapts to the adjustment of radiation direction.

Vertically two thermal-collecting tubes arranged side by side are preferably arranged between above-mentioned water-supply-pipe, and water tank, thermal-collecting tube are vertically placed from top to bottom.This arrangement mode can make the utility model hang on wall or balcony etc. and locate.The water-supply-pipe end can be added with supporting leg on this basis, makes water heater can be placed on any one sun-drenched place.

One float is arranged in the water tank, have oral siphon on the float, oral siphon is communicated with the hot water outlet pipe.

Below in conjunction with the embodiment description of drawings:

Fig. 1: structural representation of the present utility model;

Fig. 2: float reaches and hot water effluent's pipe connecting structure schematic diagram;

Fig. 3: water tank side sectional view;

Among the figure: 1 water tank, 2 heat collectors, 3 insulation films, 4 thermal-collecting tubes, 5 support bars, 6 water-supply-pipes, 7 supporting legs, 8 hot water outlet pipes, 9 cold water inlets, 10 floats, 11 float oral siphons

Respectively there is a hard water-supply-pipe 6 (endcapped) at the water tank bottom two ends, there are two to be attached thereto logical thermal-collecting tube 4 between water-supply-pipe, heat collector 2 is a curved reflector, there is reflectorized material on the surface, be connected on the thermal-collecting tube 4 by support bar 5, heat collector arc two ends are added with transparent insulation film 3, and the direction of heat collector can be stirred adjusting with hand as required.Water-supply-pipe 6 is simultaneously as the support of this water heater, and its end is equipped with the supporting leg 7 that can dismantle, and the water-supply-pipe outer surface can be added with insulation material.The float that one oblate cylindricality is arranged in the water tank remains and floats on the surface, and has half to be immersed in below the water surface, and float is embedded with four oral siphons 11, and the mouth of pipe exposes from different orientation, and the other end of oral siphon gathers with hot water outlet pipe 8 and is communicated with.

Water tank 1 can be made by heat-preserving complex material, makes it to have heat-insulating property.

Water tank 1, thermal-collecting tube 4 are vertical arrangement.

According to the principle that hot water rises, cold water sinks, when hot water floated over the upper strata, just the oral siphon by float was flowed out by the hot water outlet pipe.Supernatant hot water can also be by other known manner output.

This kind structure is owing to be rectilinear, and can hang over outside window or balcony etc. located, and for the bottom resident family of floor, the last water capacity easily realizes especially.Add supporting leg, become vertical type, can be placed on any one sun-drenched place, flexible and convenient to use.

Advantage of the present utility model:

Simple in structure, cost is low, and Heat-collecting effect is good, installs to adapt to a lot of positions, and limitation is little, and is easy to use, long service life, Be easy to promote.
