Abstract

The utility model discloses a solar water heater water tank. The upper end of the solar water heater water tank is provided with an air outlet, the air outlet is communicated with a hot water outlet through a pipeline, the solar water heater water tank is connected with a cold water pipe through a first check valve, and the cold water pipe is connected with a second check valve in bypass mode through the atmosphere. Water of the first check valve can enter the solar water heater water tank only through the cold water pipe, and water of the second check valve can enter the cold water pipe only through the atmosphere in single-direction communicating mode. The cold water pipe is communicated with a tap water pipe through a first valve, and another bypass water pipe is connected with a second valve. The solar water heater water tank has the advantages that 1 hot water can be discharged by opening valves any time according to requirements, thereby being convenient and saving. 2 no heat preservation facilities are needed, water pipes are guaranteed not to be frozen, thereby being safe and reliable.

Description

A kind of solar water heater

Technical field

The utility model relates to a kind of water heater, particularly a kind of solar water heater.

Background technology

Existing solar water heater is as shown in Figure 1, and existing solar water heater 1 upper end is provided with blast pipe 2, and the shared water pipe 3 of hot and cold water connects running water pipe 6 through valve 4 respectively and No. two valves 5 connect hot water outlet 7.There are two shortcomings in the use: 1, the same pipeline of hot water cold water, to emit cold water when using hot water, just can obtain hot water.Time spent preferably once uses up, and once uses at interval with a spot of hot water, will produce very big waste.2, be exposed to outdoor pipeline winter,, also be difficult to guarantee that water pipe is not freezed to death even if done good insulation measure, even bursting by freezing, the especially winter in the north.

Summary of the invention

To the deficiency of prior art, the solar water heater that the utility model provides a kind of hot and cold water to separate.

To achieve these goals; The technical scheme that the utility model is taked is: solar water heater water tank, and position, solar water heater water tank upper end is provided with exhaust outlet, and exhaust outlet communicates through pipeline with hot water outlet; Solar water heater water tank is connected with cold water pipe through a non-return valve; Bypass has non-return valve No. two on cold water pipe and the atmosphere, and the water of a non-return valve can only get into solar water heater water tank from cold water pipe, No. two non-return valves.Can only get into the unidirectional conducting of cold water pipe from atmosphere; Cold water pipe is communicated with running water pipe through a valve, and another Bypass hose is connected to valve No. two.

The beneficial effect of the utility model: 1, open the valve instant-heating and outlet hot, with using with putting convenient the saving; 2, without any need for lagging facility, guarantee not freeze water pipe winter, safe and reliable.

The specific embodiment

See also Fig. 2 its implementation process is described: a kind of solar water heater; Comprise solar water heater water tank 1; Position, solar water heater water tank 1 upper end is provided with exhaust outlet 2; Exhaust outlet 2 and hot water outlet 7 communicate through pipeline, and solar water heater water tank 1 is connected with cold water pipe 8 through a non-return valve 10, and bypass has non-return valve 9 No. two on cold water pipe 8 and the atmosphere; The water of a non-return valve 10 can only get into 1, No. two non-return valve 9 of solar water heater water tank from cold water pipe 8 can only get into cold water pipe 8 unidirectional conductings from atmosphere; Cold water pipe 8 is communicated with running water pipe 6 through a valve 4, and another Bypass hose is connected to valve 5 No. two.

During use, open valve 4 cold water and wash non-return valve 10 entering solar water heater water tanks 1 open No. one through cold water pipe 8.When using hot water, continue to inject cold water, hot water can overflow from original blast pipe through hot-water line and flow out, and under the full prerequisite of solar water heater water tank 1, injects how much cold water, will go out how much hot water.Prevent frozen pipe winter, open valve 5 No. two, discharge a non-return valve 10 in the cold water pipe, stoped letting out in the water tank under water, No. two valve 5 has played the air inlet effect, helps the water pipe emptying, has reached the antifreezing effect of water pipe.
