Abstract

The utility model relates to a solar water heater technology, and the solar water heater technology comprises a water tank, a down-flow pipe, an evacuating device, an air supply opening, a water outlet faucet and an air exhaust pipe. The utility model is characterized in that the upper end of the air exhaust pipe is arranged at the position higher than the highest point of the water level of the water tank, the lower end of the air exhaust pipe is connected in the down-flow pipe under the evacuating device, to make the height difference between the evacuating device and the lower end of the air exhaust pipe is not less than the height difference between the water outlet faucet and the down-flow pipe. After the user turns on the water faucet, the air from the evacuating device to the lower end of the air exhaust pipe is discharged through the air exhaust pipe, decreasing the air volume in the down-flow pipe, making the water out smooth, being capable of effectively preventing the air binding, and ensuring the normal water utilization.

Description

A kind of emptying type solar water heater

The utility model relates to the solar water heater technology.

In order to prevent that winter solar energy water heater downcomer from freezing,,, guarantee the normal solar water heater that uses in time with the surplus water emptying of pipeline emptier being installed near on the downcomer of water tank.But because certain customers are limit at indoor conditions, make downcomer tortuous up and down, form repeatedly U type pipe, when emptying, U type pipe bottom ponding can't be discharged fully.When the user opens when using tap once more, it is stifled to be easy to generate gas, and following water is not smooth, and influence is used.

The purpose of this utility model be design a kind of not have gas stifled, guarantee the emptying type solar water heater in the smooth road of water outlet.

The utility model comprises water tank, downcomer, emptier, gas supplementing opening, depotition cock, blast pipe, the upper end that is characterized in blast pipe is arranged on and is higher than more than the cistern water level peak, the lower end of blast pipe is connected in the downcomer of emptier below, and makes emptier and blast pipe lower end difference in height be not less than the difference in height of depotition cock and downcomer minimum point.

After the user fetches boiling water tap, emptier to the air of blast pipe lower end through emission by exhaust pipe, reduce volume of air in the downcomer, it is smooth to use current, guarantees normal water.

For anti-sealing from the blast pipe spill and leakage, the upper end of blast pipe is placed in the water tank, and is positioned at more than the water tank peak level.

Now in conjunction with the accompanying drawings, further specify embodiment.

Fig. 1 is a kind of structural representation of the present utility model;

Fig. 2 is an another kind of structural representation of the present utility model;

Fig. 3 is a kind of structural representation that has the water heater of secondary water tank;

Fig. 4 is an another structural representation of the present utility model.

Among Fig. 1,1 water tank, 2 flexible pipes, 3 emptier, 4 joints, 5 downcomers, 6 usefulness taps, 7 water pipes, 8 elbows, 9 threeways, 10 blowdown pipes.

Downcomer 5 has the function of upper hose concurrently, the lower end connecting bend 8 of water pipe 7, and elbow 8 is connected on the downcomer 5 by threeway 9; The upper end of water pipe 7 connects flexible pipe 2 by joint 4, and the other end of flexible pipe 2 is through in the blowdown pipe 10.

Difference in height as threeway 9 and emptier 3 is H, and the downcomer 5 tortuous bottoms that form and each water are L1, L2, L3, L4 with the difference in height of 6 formation of tap; Then should make

H≥MAX(L1，L2，L3，L4)。

Among Fig. 2, emptier 3 ' below downcomer 5 ' on serial connection pressure-bearing joint 16.Flexible pipe 2 ' the upper end stretch into blowdown pipe 10 ' in, the lower end by sealing ring by the through hole of pressure-bearing joint 16 1 sides stretch into downwards downcomer 5 ' make flexible pipe 2 ' the lower end and emptier 3 ' height difference H ' satisfy

H′≥MAX(L1′，L2′，L3′，L4′)。

Among Fig. 3, same Fig. 1 of lower end connected mode of water tank 1 " go up auxiliary connection water tank 11, secondary water tank 11 is connected with upper hose 12, blowdown pipe 14, water pipe 7 ", water pipe 7 " the upper end connect threeway 13, two through holes in addition of threeway 13 are the blowdown pipe 14 on the auxiliary connection water tanks, vertical blank pipe 15 respectively.The same Fig. 1 of other connected mode.

Among Fig. 4, " be arranged in water tank 1 , its below is stretched out water tank 1 downwards to blowdown pipe 10.Connection pressure-bearing joint 16 on downcomer 5 below emptier 3 ', the upper end of flexible pipe 2 is upwards extend among water tank 1 by blowdown pipe 10 , and in the upper end bending, the other end of flexible pipe 2 stretches into downcomer 5 by sealing ring downwards by the through hole of pressure-bearing joint 16 ' one sides, and the lower end of flexible pipe 2 and the height difference H of emptier 3 are satisfied

H≥MAX(L1，L2，L3，L4)。
