Abstract
The utility model discloses an emptying solar water heater, comprising a water tank, upper and lower water pipes, and an overflow pipe, wherein the overflow pipe is connected with the top of the water tank; an emptying pipe is arranged on the top of the water tank; a vertical tee joint is positioned on the water tank; the lower end of the tee joint is connected with a water feeding suction pipe; the lower end of the water feeding suction pipe is extended to the bottom of the water tank; the lower side of the tee joint is connected with the upper and lower water pipes; the top of the tee joint is connected with the emptying pipe; and the lower end of the emptying pipe is provided with an emptying valve. The emptying solar water heater solves the problems of freezing or frost cracking of the upper and lower solar water pipes in winter, facilitates the heater user, and prevents maintenance trouble and economic loss.
Description
Technical field
The utility model relates to a kind of solar water heater, especially a kind of drain-solar water heater.
Background technology
Prior solar water heater under the situation of water in the water tank, also has been filled with water in the upper and lower conduit, water uses under the winter of cold, upper and lower conduit froze influence easily, and upper and lower conduit is brought constant and economic loss by bursting by freezing to the user when serious.
Summary of the invention
The purpose of the utility model provides a kind of drain-solar water heater, solves the problem that the solar energy upper and lower conduit freezes in winter easily.
The purpose of the utility model realizes as follows: this drain-solar water heater comprises water tank and upper and lower conduit, overflow pipe; Overflow pipe is connected in tank top, on the water tank top blast pipe is set, and above water tank, is provided with vertical threeway; The lower end of threeway connects the water inlet suction hose; The lower end of water inlet suction hose extend into the bottom in the water tank, and threeway side bottom connects upper and lower conduit, and the threeway top connects evacuated tube; Exhaust-valve is equipped with in the lower end of evacuated tube, and exhaust-valve can use stop valve or control valve.Overflow pipe, upper and lower conduit, evacuated tube are all received in the bathroom; Upper and lower conduit connects mixed water valve and is connected to other device with hot water through piping; Mix water valve and connect running water and the shower nozzle of having a bath, replenish running water or from water tank hot water is provided downwards to solar water container through upper and lower conduit, the effect of overflow pipe is when giving the solar water container moisturizing; Water can flow out in overflow pipe after water tank is full of, and is convenient to reminds people and in time closes the moisturizing valve; Exhaust-valve on the evacuated tube is in closed condition usually.Only after giving the solar water container moisturizing or use hot water winter, open the arbitrary penstock of using on the upper and lower conduit, open the exhaust-valve on the evacuated tube then; Air gets in the threeway through evacuated tube; Water in the threeway flow in the water tank through the water inlet suction hose, and water is closed exhaust-valve then and used penstock through discharging with penstock in the upper and lower conduit; Owing to no longer be full of water in the upper and lower conduit, also just can not occur freezing stifled phenomenon in the winter of cold.When using hot water, open the valve that fills the tank with water, to injecting part of running water in the upper and lower conduit, to open then and use penstock, the hot water in the water tank just can be extracted through siphon principle.After using up hot water, once more exhaust-valve is opened upper and lower conduit is carried out the emptying operation.
The utility model has solved the problem that solar energy upper and lower conduit in the winter time freezes stifled or bursting by freezing, has brought facility for the solar water heater user, has also avoided trouble and the economic loss of maintenance.
Description of drawings
Accompanying drawing is the structural representation of the utility model.
The specific embodiment
With reference to accompanying drawing, this drain-solar water heater comprises water tank 1 and upper and lower conduit 5, overflow pipe 4, and overflow pipe 4 is connected in water tank 1 top; On water tank 1 top blast pipe 7 is set, above water tank 1, is provided with vertical threeway 2, the lower end of threeway 2 connects water inlet suction hose 3; The lower end of water inlet suction hose 3 extend into the bottom in the water tank 1; Threeway 2 side bottoms connect upper and lower conduit 5, and threeway 2 tops connect evacuated tube 6, and exhaust-valve 8 is equipped with in the lower end of evacuated tube 6.
