Description
Technical field
The utility model relates to the solar water heater field, relates in particular to a kind of downcomer automatic emptier of solar water heater.
Background technology
Solar water heater extremely people's favor with its energy savings, environmental protection almost has been applied to every household.In the prior art, the antifreeze problem when using in the winter time for the downcomer that solves solar water heater, taking of having adds a heating tape around downcomer, by electrical heating downcomer is not frozen winter; What have adds a magnetic valve on the outlet pipe of the outdoor storage tank of solar water heater, after the water, close this magnetic valve, opens water nozzle, and the water in the sewer pipe is discharged.Though the effect that the downcomer of solar water heater does not freeze winter is all played in these measures, but still has some shortcomings: the waste electric energy; Because magnetic valve is in outside the storage tank, freezing possibility is also arranged, and the service life of magnetic valve is shorter, general two to three years.This has increased very big use cost undoubtedly.
In order to address the above problem, the patent No. is the Chinese utility model patent of CN200520113381.0, disclose such technical scheme: a kind of solar water heater with pipeline exhausting device includes water tank, upper and lower conduit, return pipe, evacuated tube, ball float, backwater valve, the general pipe of backwater emptying.The indoor end of upper and lower conduit is provided with taps, is provided with hot water outlet pipe and hot-water switch on the upper and lower conduit above the last taps, and the end of upper and lower conduit in water tank bends to the inverted u-shaped shape, and port is positioned at the water tank cavity bottom; Evacuated tube is connected by the upper and lower conduit of unidirectional command valve with the horizontal segment on water tank cavity top, and the indoor end of the general pipe of backwater emptying is provided with the emptying switch; Return pipe is located at the water tank outside, and an end is connected with evacuated tube and the general pipe of backwater emptying, and the other end is provided with backwater valve, and the ball float in backwater valve and the water tank is connected.Like this, though the problem that has solved the waste electric energy and used magnetic valve to raise the cost, but still have following defective: because its parts are quite a lot of, troublesome poeration uses more complicated, causes user's inconvenience.
The utility model content
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, a kind of energy-conserving and environment-protective, the downcomer automatic emptier that has the solar water heater of fine antifreezing effect again easy to use are provided.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of downcomer automatic emptier of solar water heater, comprise attemperater, downcomer, it is characterized in that: the upper end that is arranged in the described downcomer in the described attemperater is for falling " U " shape pipe; The lower end of described downcomer is provided with indoor water butt, on the described downcomer, between described attemperater and the indoor water butt drainage switch is set;
Preferably, be provided with " U " shape gap in the bottom heat-insulation layer of described attemperater, described " U " shape pipe is arranged in described " U " shape gap;
Preferably, the upper surface of the bottom heat-insulation layer of the most significant end of described " U " shape pipe and described attemperater is in same horizontal plane; The spout part of described " U " shape pipe is for falling funnel-form; Be provided with heat-insulation layer in the described indoor water butt.
Preferably, described " U " shape pipe most significant end is lower than the upper surface of the bottom heat-insulation layer of described attemperater; The spout part of described " U " shape pipe is for falling funnel-form; Be provided with heat-insulation layer in the described indoor water butt.
Compared with prior art, the beneficial effects of the utility model are: even use solar water heater cold winter, and after making water at every turn, the also water in the emptying sewer pipe automatically, both play the effect that its downcomer does not freeze winter, energy-conserving and environment-protective again, reduced cost.And, many convenience are provided to the user because its installation is simple, easy to operate.
