Description

A kind of double-layer tank solar water heater

Technical field

The utility model relates to the solar energy equipment field, specifically a kind of double-layer tank solar water heater.

Background technology

At present, the solar water heater on the market only has an inner bag, re-uses after the gallbladder channel heating in cold water injects, and injects again cold water after using and reheats, and the phenomenon that can occur repeatedly heating like this can cause following problem:

1, the content of the calcium in the inner bag, magnesium, chlorine plasma is accumulated in a large number, causes the interior fouling of inner bag more serious, often stops up outlet conduit, uses water quality also to be greatly affected;

2, incrustation scale condenses in vacuum heat collection pipe for the larger impact of its thermal-arrest generation;

3, the chlorion in the water has corrosiveness to water tank, affects the service life of water tank.Especially in the relatively poor area of water quality, very serious to the water tank corrosion, use once, the problem of radiator leak appearred in 2 years;

4, common water tank generally can only be done and scrap processing after inner bag is subjected to the negative pressure suction flat, and is higher to user's instructions for use.

The utility model content

The problem that exists in order to solve above-mentioned prior art, the utility model provides a kind of double-layer tank solar water heater, inside and outside two courages of this water heater, inner bag is deposited and is made water, and outer courage is deposited heating water, and heating water is connected with vacuum heat collection pipe, make water separate operation with heating water, the water yield is certain, has limited the content of calcium, magnesium, chlorine plasma, avoids inner-outer tube, water tank and the vacuum heat collection pipe too much incrustation scale and impurity to occur.The inner bag of simultaneously two courage water tanks still can normally use after suction is flat.

The technical solution of the utility model is: a kind of double-layer tank solar water heater, include outer courage, inner bag, secondary water tank, described outer courage is insulation material between it in the inside of outer barrel skin, inner bag is the inside of courage outside, and the end of inner bag is fixedly connected with the end of outer courage; Bottom and the vacuum heat collection pipe of the interlayer cavity that forms between inner bag and the outer courage communicate, and this interlayer cavity is communicated with secondary water tank by outer courage filling pipe; Described secondary water tank places water tank upper, and it links to each other with the cold water filling pipe, and communicates with inner bag by the inner bag filling pipe; Described cold water filling pipe is connected with cold water pipe.

The structure of general solar water heater mainly is comprised of outer barrel skin, insulation material, inner bag, probe mouth, delivery port, mudhole, outlet pipe, cold water upper hose, magnetic valve, mixed water valve, shower nozzle, cold water pipe, vacuum heat collection pipe, support.Between outer barrel skin and the inner bag insulation material is arranged, inner bag is fixed on outer barrel intracutaneous section, and there is the probe mouth inner bag side top, and there are delivery port and mudhole in the inner bag below; Described cold water pipe is divided into two, and one is connected with the cold water upper hose by magnetic valve, and another is connected with outlet pipe by mixed water valve, and mix water valve and be connected with shower nozzle,

The cold water upper hose is connected with outlet pipe, and outlet pipe is connected with delivery port.The bottom of inner bag communicates with vacuum heat collection pipe, and vacuum heat collection pipe and water tank place on the support.

Operation principle is: general cold water pipe supply cold water, often open, and the magnetic valve automatic loading water, normally closed.

During upper water, magnetic valve leaves, and mixed water valve cuts out, and cold water enters inner bag through cold water pipe, cold water upper hose, outlet pipe, delivery port, and holds full water to inner bag; Another road cold water passes through cold water pipe, cold water filling pipe, enters secondary water tank, and secondary water tank retaining is to certain water yield, and water enters the interlayer cavity through outer courage filling pipe, and holds full interlayer cavity.

In the work, vacuum heat collection pipe absorbs solar radiant heat, and the cold water of heating, vacuum thermal-collecting tube utilizes thermal cycle that heat is conducted to interlayer cavity ponding, when ponding water temperature rising after heat is conducted to the cold water in the inner bag, until ponding and inner bag cold water water temperature equate.

After inner bag water or the decline of the cavity ponding water yield, secondary water tank namely carries out moisturizing by filling pipe to inner bag and cavity.The decline of inner bag water mainly is that inner bag water is discharged as making water so that the water yield descends, and the decline of cavity ponding mainly is the former thereby declines such as evaporation.

During water, shut electromagnetic valve is opened mixed water valve, and hot water and the next cold water mix of cold water pipe come from outlet pipe flow out from shower nozzle, for.
