Abstract

The utility model relates to a solar water heater. The solar water heater comprises a water tank and a coiler. One side of the water tank is connected with a water tank water inlet pipe, and the other side of the water tank is connected with a water return pipe. A hole is formed at each of the two ends of the upper surface of the water tank, and the coiler penetrates into the water tank through the hole of one end and penetrates out of the water tank through the other hole. The interior of the water tank is covered with the portion of the coiler in the water tank in a smooth curved shape, the maximum height of the portion of the coiler in the water tank is not larger than the height of the position of the water tank and the water return pipe connection position, and water in the coiler is guaranteed to be heated to the usable temperature. One end of the coiler, which penetrates out of the water tank, is connected with a cold water inlet pipe. The heat-conducting coiler in the water tank is connected with the cold water inlet pipe through a control valve. One end of the coiler, which enters the water tank, is connected with a water outlet pipe. The coiler is made of heat-conducting materials. Water is heated when flowing through the coiler, so that trouble caused by direct usage of water containing impurities and incrustation in the water tank is prevented, and pipe explosion caused by air drying due to the fact that water is not injected timely in the water tank is prevented.

Description

A kind of solar water heater

Technical field

The utility model relates to a kind of solar energy heat distribution system, particularly a kind of solar water heater.

Background technology

At present, solar water heater in life is all directly the water being contained in water tank directly to be emitted, this solar water heater structure is simple, easy to use, but owing to injecting running water for a long time in water tank, can make water tank inner accumulated impurity and incrustation scale, then while injecting running water to water tank, impurity and incrustation scale can pollute the water quality in water tank, are unfavorable for direct use.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of solar water heater, and this solar water heater has avoided direct use water tank to contain the water of impurity.

For achieving the above object, the utility model provides following technical scheme: a kind of solar water heater, comprise water tank, coil pipe, one side of water tank connects tank inlet pipe, opposite side connects return pipe, the two ends of water tank upper surface arrange hole, coil pipe pierces into water tank from the hole of one end, and pass water tank from another hole, the part of coil pipe in water tank inside is round and smooth bending and is covered with water tank inside, and the part maximum height of coil pipe in water tank inside do not connect the height at return pipe place higher than described water tank, coil pipe connects hot water outlet pipe in the one end that passes water tank, hot water outlet pipe is connected with cold water water inlet pipe by mixed water valve, coil pipe connects water inlet pipe in the one end that enters water tank, coil pipe adopts Heat Conduction Material to make.

Preferably, water inlet pipe is being connected with tank inlet pipe by conduit by subterminal position, and water inlet pipe locates to arrange valve endways, and conduit arranges same valve, the end connecting tap of tank inlet pipe.

Adopt technique scheme, a kind of solar water heater, comprise water tank, coil pipe, one side of water tank connects tank inlet pipe, opposite side connects return pipe, the two ends of water tank upper surface arrange hole, coil pipe pierces into water tank from the hole of one end, and pass water tank from another hole, the part of coil pipe in water tank inside is round and smooth bending and is covered with water tank inside, and the part maximum height of coil pipe in water tank inside do not connect the height at return pipe place higher than described water tank, guaranteed that the water in coil pipe is heated to operable temperature, coil pipe connects hot water outlet pipe in the one end that passes water tank, hot water outlet pipe is connected with cold water water inlet pipe by mixed water valve, coil pipe connects water inlet pipe in the one end that enters water tank, thereby water is heated when flowing through coil pipe, the trouble of having avoided water tank to contain direct use of water of impurity and incrustation scale and having caused, avoid because not having timely injected water to cause bombing after air drying in water tank simultaneously, coil pipe adopts Heat Conduction Material to make, can Fast Heating flow through the water in coil pipe.

Water inlet pipe is being connected with tank inlet pipe by cold water conduit by subterminal position, water inlet pipe locates to arrange valve endways, cold water conduit arranges same valve, the end connecting tap of tank inlet pipe, make this solar water heater can emptying water inlet pipe when not using and tank inlet pipe in water, avoid water pipe when winter because water pipe contains water frozen block.

Accompanying drawing explanation

Fig. 1 is the utility model structural representation;

Wherein, 1. water tank 2. coil pipe 3. water inlet pipe 4. Water tap 5 running water water inlet 6 tap 7. cold water water inlet pipes 8. mix water valve 9. return pipe 10. hot water outlet pipe's 11. valve 12. tank inlet pipe 13. hole 14. cold water conduits.

The specific embodiment

Below in conjunction with accompanying drawing, the description by embodiment, is described further the utility model:

Fig. 1 is structural representation of the present utility model, a kind of solar water heater, comprise water tank 1, coil pipe 2, one side of water tank 1 connects tank inlet pipe 12, opposite side connects return pipe 9, the two ends of water tank 1 upper surface arrange hole 13, coil pipe 2 pierces into water tank 1 from the hole 13 of one end, and pass water tank 1 from another hole 13, the part of coil pipe 2 in water tank 1 inside is round and smooth bending and is covered with water tank 1 inside, and the part maximum height of coil pipe 2 in water tank 1 inside do not connect the height at return pipe 9 places higher than described water tank 1, guaranteed that the water in coil pipe 2 is heated rapidly to operable temperature, coil pipe 2 connects hot water outlet pipe 10 in the one end that passes water tank 1, hot water outlet pipe 10 is connected with cold water water inlet pipe 7 by mixed water valve 8, coil pipe 2 connects water inlet pipe 3 in the one end that enters water tank 1, coil pipe 2 adopts Heat Conduction Material to make, water is heated when flowing through coil pipe 2, the trouble of having avoided water tank 1 to contain direct use of water of impurity and incrustation scale and having caused, avoid because not having timely injected water to cause bombing after air drying in water tank 1 simultaneously, water inlet pipe 3 is being connected with tank inlet pipe 12 by conduit 14 by subterminal position, water inlet pipe 3 locates to arrange valve 11 endways, same valve 11 is set on cold water conduit 14, the end connecting tap 6 of tank inlet pipe 12, make this solar water heater at any time can emptying water inlet pipe 3 and tank inlet pipe 12 in water, avoid water pipe when winter because water pipe contains water frozen block.
