Abstract
A solar energy water heater is characterized in that a water conduit is arranged in the outer end cover of a water tank and on the lateral surface of a barrel in the water tank, is horizontally led out of the lowest point of the lateral surface of the barrel in the water tank, extends perpendicularly upwards above the highest point of the barrel in the water tank along the side outer wall of the barrel in the water tank, and is divided into two pipelines through a three-way pipe fitting: one extends downward to serve as a water feeding and discharging pipe, while the other one vertically extends upward above the water feeding and discharging pipe and then extends downward to serve as an evacuation operating pipe, and an evacuation operating valve is arranged at one end of the evacuation operating pipe. When in use, the evacuation operating valve and a hot water blow-off valve for the solar energy water heater are opened, the air enters from the evacuation operating pipe, so as to ensure that the air pressure at the highest point of the water feeding and discharging pipe equals to that of the hot water blow-off valve, and the water from the highest point of the water feeding and discharging pipe to the hot water blow-off valve flows out of the hot water blow-off valve, so that the water in the exposed water feeding and discharging pipe is evacuated, thereby achieving the effect of preventing the water feeding and discharging pipe from being frozen block.
Description
Affiliated technical field
The utility model relates to a kind of solar water heater, but the water emptying in the upper and lower conduit road prevents that freezing of solar water heater upper and lower conduit road is stifled.
Background technology
Before the utility model proposes, but known emptying prevents that the upper and lower conduit road from freezing stifled solar water heater and being:
Add a device case at the solar water heater water tank top, the device case is drawn an aqueduct vertically downward and is inserted bucket bottom in the solar water heater water tank.In the device case, by a threeway aqueduct is divided into two pipelines: one is upper and lower conduit, and another root is an emptying operation pipe, and an end of operating pipe in emptying is equipped with emptying operation valve.Open emptying operation valve and solar water heater hot water discharging valve during use, air is entered by emptying operation pipe, upper and lower conduit peak air pressure is equated with hot water discharging valve air pressure, solar water heater upper and lower conduit peak to the water in the hot water discharging valve just flows out from the hot water discharging valve, make the water emptying in the upper and lower conduit road of exposing, reached and prevent that the upper and lower conduit road from freezing stifled effect.
But this emptying prevent the upper and lower conduit road freeze stifled solar water heater make complicated, the production cost height.
Summary of the invention
The utility model proposes a kind of solar water heater of new construction, its technical scheme is: the bucket side is provided with an aqueduct in an outer end cap of solar water heater water tank, in the water tank, horizontal direction bucket side minimum point in the water tank is drawn, along the bucket peak top to the water tank upwards of bucket side outer wall vertical in the water tank, be divided into two pipelines by a tee pipe fitting: one is upper and lower conduit downwards, another root is downwards emptying operation pipe vertically upward again to the upper and lower conduit top, and an end of operating pipe in emptying is provided with emptying operation valve.
Open emptying operation valve and solar water heater hot water discharging valve during use, air enters from emptying operation pipe, upper and lower conduit peak air pressure is equated with hot water discharging valve air pressure, solar water heater upper and lower conduit peak to the water in the hot water discharging valve just flows out from the hot water discharging valve, make the water emptying in the upper and lower conduit road of exposing, reached and prevent that the upper and lower conduit road from freezing stifled effect.
But the utility model prevents that with respect to known emptying the upper and lower conduit road from freezing that stifled solar water heater is advantageous to be: make simple, production cost is low.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
But being emptying, Fig. 1 prevents that the upper and lower conduit road from freezing the structural map of stifled first embodiment of solar water heater.
But being emptying, Fig. 2 prevents that the upper and lower conduit road from freezing the structural map of second embodiment of stifled solar water heater.
1. solar water heater water tanks among the figure, 2. bucket in the water tank, 3. aqueduct, 4. in barrel side outer wall, 5. water tank outer end cap, 6. hot water discharging valve, 7. emptying operation valve, 8. tee pipe fitting, 9. upper and lower conduit, 10. emptying operation pipe.
The specific embodiment
In the embodiment shown in fig. 1, bucket 2 sides are provided with an aqueduct 3 in 1 one water tank outer end caps 5 of solar water heater water tank, in the water tank, horizontal direction is drawn along interior bucket side outer wall 4 bucket 2 peaks top to the water tank vertically upward from bucket 2 minimum points in the water tank, be divided into two pipelines by a tee pipe fitting 8 in water tank outer end cap 5: along continuous straight runs is drawn from water tank outer end cap 5 and is upper and lower conduit 9 downwards, another root vertically upward to upper and lower conduit 9 tops again along continuous straight runs draw downwards by water tank outer end cap 5 and manage 10 for the emptying operation.End at emptying operation pipe 10 is provided with emptying operation valve 7.Open emptying operation valve 7 and solar water heater hot water discharging valve 6 during use, air is entered by emptying operation pipe 10, upper and lower conduit 9 peak air pressure are equated with hot water discharging valve 6 air pressure, solar water heater upper and lower conduit 9 peaks to the water in the hot water discharging valve 6 just flows out from hot water discharging valve 6, make the water emptying in the upper and lower conduit that exposes 9, reached and prevent that the upper and lower conduit road from freezing stifled effect.
In embodiment illustrated in fig. 2, bucket 2 sides are provided with an aqueduct 3 in 1 one water tank outer end caps 5 of solar water heater water tank, in the water tank, horizontal direction is drawn along interior bucket side outer wall 4 bucket 2 peaks top to the water tank vertically upward from bucket 2 minimum points in the water tank, after horizontal direction is drawn from water tank outer end cap 5, be divided into two pipelines by a tee pipe fitting 8 again: one is upper and lower conduit 9 downwards, and another root is emptying operation pipe 10 vertically upward downwards to upper and lower conduit 9 tops.End at emptying operation pipe 10 is provided with emptying operation valve 7.Open emptying operation valve 7 and solar water heater hot water discharging valve 6 during use, air is entered by emptying operation pipe 10, upper and lower conduit 9 peak air pressure are equated with hot water discharging valve 6 air pressure, solar water heater upper and lower conduit 9 peaks to the water in the hot water discharging valve 6 just flows out from hot water discharging valve 6, make the water emptying in the upper and lower conduit that exposes 9, reached and prevent that the upper and lower conduit road from freezing stifled effect.
