Abstract

The utility model discloses a solar water heater provided with a freeze-proof device, which comprises a solar collector. The solar collector is provided with a collector pipe communicated with the inside and the outside of a water tank of the solar collector; the extension end of the collector pipe is connected with a main pipe, end of which is provided with a solar control valve, the lower end of the collector pipe is close to the bottom of the container of the solar water heater and the upper end of the collector pipe extends upwards outside the water tank of the solar collector; the upper pipe of a part of the collector pipe which extends outside the water tank is connected with an emptying pipe which extends to the operating part of the solar and the end of the emptying pipe is provided with a blowoff valve; when the blowoff valve is opened, the water in the main pipe flows out and the water in the collector pipe flows into the solar collector, which helps draw off the water in the outdoor pipe of the solar collector and prevents pipe from frost crack which results from that water is frozen in the pipe in cold winter and results in frequent maintenance. The utility model has simple structure, easy operation, safe application, low cost and convenient installation.

Description

Solar water heater with defroster

Technical field

The utility model relates to a kind of solar water heater, relates in particular to a kind of solar water heater with defroster.

Background technology

Along with the raising of people's living standard, solar water heater is used more and more wider in people's life, and solar water heater all has outdoor water pipe, for the user's in the north, if the water in the winter water pipe does not drain, the water in the water pipe is freezed, and the bursting by freezing water pipe.Solar water heater generally is placed on the roof, not only makes to repair very inconvenience, and has increased the cost of its product again.

The utility model content

Technical problem to be solved in the utility model provides a kind of solar water heater with defroster that can prevent the outdoor water pipe from freezing crack of solar water heater.

For solving the problems of the technologies described above, the technical solution of the utility model is: the solar water heater with defroster, comprise solar thermal collector, described solar thermal collector is provided with and is communicated with the inside and outside heat collector water pipe of described solar thermal collector water tank, the external part of described heat collector water pipe is connected with person in charge's deferent, the end of described trunk line is equipped with the solar energy control valve, the lower end of described heat collector water pipe is near the bottom of solar water heater liner, the upper end of described heat collector water pipe protrudes upward the water tank of described solar thermal collector, and described heat collector water pipe stretches out, and pipe is connected with evacuated tube on the water tank pipeline partly, described evacuated tube extends to solar energy operation place, and the tail end of described evacuated tube is equipped with exhaust-valve.

As a kind of improvement, the pipe junction of described heat collector water pipe, trunk line and evacuated tube is equipped with tee pipe coupling.

Owing to adopted technique scheme, solar water heater with defroster, comprise solar thermal collector, described solar thermal collector is provided with and is communicated with the inside and outside heat collector water pipe of described solar thermal collector water tank, the external part of described heat collector water pipe is connected with person in charge's deferent, the end of described trunk line is equipped with the solar energy control valve, the lower end of described heat collector water pipe is near the bottom of solar water heater liner, the upper end of described heat collector water pipe protrudes upward the water tank of described solar thermal collector, and described heat collector water pipe stretches out, and pipe is connected with evacuated tube on the water tank pipeline partly, described evacuated tube extends to solar energy operation place, and the tail end of described evacuated tube is equipped with exhaust-valve; When opening exhaust-valve, can be because the connection of described evacuated tube, under atmospheric effect, the water that makes trunk line flows out and water in the heat collector water pipe flows in the solar thermal collector, makes at solar thermal collector ducted water out of doors and drains, prevent in the winter of cold pipeline that water is frozen in water pipe from freezing crack and often maintenance, and this simple in structure, operation is safe in utilization easily, cost is low, and is easy for installation.

Description of drawings

Accompanying drawing is the structural representation of the utility model embodiment.

The specific embodiment

As shown in drawings, solar water heater with defroster, comprise solar thermal collector 1, described solar thermal collector 1 is provided with and is communicated with the inside and outside heat collector water pipe 2 of described solar thermal collector 1 water tank, the external part of described heat collector water pipe 2 is connected with trunk line 4 pipes, the end of described trunk line 4 is equipped with solar energy control valve 9, solar energy control valve 9 is combined by water supply valve 6 and hot water valve 7, the lower end of described heat collector water pipe 2 is near the bottom of solar water heater liner, the upper end of described heat collector water pipe 2 protrudes upward the water tank of described solar thermal collector 1, and described heat collector water pipe 2 stretches out, and pipe is connected with evacuated tube 5 on the water tank pipeline partly, described evacuated tube 5 extends to solar energy operation place, and the tail end of described evacuated tube 5 is equipped with exhaust-valve 8.

The pipe junction of described heat collector water pipe 2, trunk line 4 and evacuated tube 5 is equipped with tee pipe coupling 3.

The operation principle of present embodiment is as follows:

When giving solar thermal collector 1 water filling, close hot water valve 7 and exhaust-valve 8, open water supply valve 6, give solar thermal collector 1 water filling, when filling with water, close water supply valve 6, open hot water valve 7 and exhaust-valve 8, this moment can be because the connection of described evacuated tube 5 under atmospheric effect, makes the water of trunk line 4 drain from hot water valve 7, water in the heat collector water pipe 2 flows in the solar thermal collector 1, have the water in the water tank of solar thermal collector like this, all pipelines no longer include water and exist, thereby reach antifreeze purpose.

When using the hot water of solar thermal collector 1, close hot water valve 7, open water supply valve 6, make in the trunk line 4 behind the water-filling, turn off water supply valve 6 and exhaust-valve 8, open hot water valve 7, because the effect of siphon, the cold water in the trunk line 4 draws the hot water in solar thermal collector 1 water tank get off, and uses to get final product; After finishing using, open exhaust-valve 8 and hot water valve 7, this moment can be because the connection of described evacuated tube 5, the water of trunk line 4 is drained from hot water valve 7, water in the heat collector water pipe 2 flows in the solar thermal collector 1, have the water in the water tank of solar thermal collector equally, all pipelines no longer include water and exist, and have also reached antifreeze purpose.

Vertical the above, the utility model can make solar thermal collector is exposed at does not have water in the outdoor pipeline existence, can be because of cold of weather, allow ducted water freezing, with water pipe from freezing crack, and simple in structure, easy to operate, cost is lower.
