Description

A kind of energy-efficient anti-frozen solar energy water heater

Technical field

The utility model relates to a kind of solar water heater, relates in particular to a kind of have antifreezing function and the long energy-efficient solar water heater of temperature retention time.

Background technology

At present, solar water heater has obtained extensive utilization in a lot of places, as long as sunshine is arranged, just can produce hot water, has utilized solar energy resources well.But, the regular solar water heater all is that blast pipe is installed above incubator, exhaust outlet up, hot water in the incubator is filled in the blast pipe, because the hot and cold water density contrast makes hot water constantly toward cocycle, so blast pipe causes the heat loss especially severe, insulating efficiency is low, and such water heater hot-water temperature is not high, and temperature retention time is short; On the other hand, this water heater because water is arranged, freezes stifledly in the blast pipe when ice up in winter easily, and the incubator inner bag is easily taken out flat; If blast pipe is done thinnerly, also stopped up by the foreign material in the water easily, it is flat to cause the incubator inner bag to be taken out.Have a strong impact on the effect and the life-span of solar water heater.Also there is the people that this common solar water heater is improved, glass heat-collecting vacuum tube is set on incubator, but because the defective of this material of glass heat-collecting vacuum tube itself, fragile, and it and incubator connected mode instability, often cause exhaust to be obstructed, make the incubator explosion.

The utility model content

Technical problem to be solved in the utility model is, overcomes the above defective, the solar water heater that provide a kind of and have antifreezing function, heat loss is low, the thermal efficiency is high, temperature retention time is long.

In order to solve above technical problem, a kind of energy-efficient anti-frozen solar energy water heater of the utility model, comprise water supply tank, incubator, cold water filling pipe, hot water delivery pipe, thermal-collecting tube, blast pipe, the cold water filling pipe is communicated with water supply tank and incubator, the hot water delivery pipe is communicated with incubator, described incubator top is provided with coupled logical negative incubator, and described blast pipe is connected with negative incubator; The horizontal plane that is higher than water supply tank and negative incubator suitable for reading of blast pipe, the following mouth down of blast pipe.

As improvement, a kind of energy-efficient anti-frozen solar energy water heater of the utility model, described blast pipe can insert incubator from the incubator bottom and enter in the negative incubator.Described negative incubator adopts metal material to make, and is connected for a silk tooth between negative incubator and the incubator.

A kind of energy-efficient anti-frozen solar energy water heater of the utility model, running water provides cold water to water supply tank, and water supply tank replenishes cold water by the cold water filling pipe in incubator, and when needing to use hot water, the valve of opening the hot water delivery pipe can use hot water.On the incubator top, a coupled logical negative incubator is set, blast pipe is connected with negative incubator, the horizontal plane that is higher than water supply tank and negative incubator suitable for reading of blast pipe, the following mouth down of blast pipe, like this, there is not water full in the whole blast pipe, the heat loss of incubator by blast pipe seldom, negative incubator has heat-insulation layer equally, water in the whole incubator well is incubated, the hot water temperature is very longer than general solar water heater height and temperature retention time, can prolong temperature retention time about 50% than regular solar water heater; Owing to do not have water in the blast pipe, also just avoided cause blast pipe to freeze stifled, incubator inner bag taking out phenomenon flat and the incubator explosion, can prolong the service life of solar water heater greatly winter because of icing; Negative incubator adopts metal material to make, be connected with adopting the silk tooth between the incubator, guarantee the two be connected firmly, stablize, level and smooth, negative incubator only is connected with the outer wall of incubator, need not insert in the inner bag of incubator, the junction is smoothly unobstructed, and exhaust is unblocked, and incubator is difficult for by the gas support quick-fried like this.The horizontal plane a little more than water supply tank and negative incubator suitable for reading of blast pipe, tiny foreign material in the incubator have with a certain distance from the suitable for reading of blast pipe, can not block steam vent, guarantee that from many aspects the exhaust of water heater is unimpeded, avoid incubator quick-fried, prolong the service life of solar water heater by the gas support.

The beneficial effects of the utility model: owing to used the above structure, the utility model is compared with the regular solar water heater, have the design ingenious, simple in structure, easy making, heat radiation is low, the thermal efficiency is high, the hot water temperature is high, temperature retention time is long, good frost resistance, advantages such as long service life have good social benefit and economic benefit.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail.

A kind of energy-efficient anti-frozen solar energy water heater of the utility model, comprise water supply tank 1, incubator 2, cold water filling pipe 3, hot water delivery pipe 4, thermal-collecting tube 5, blast pipe 6, cold water filling pipe 3 is communicated with water supply tank 1 and incubator 2, hot water delivery pipe 4 is communicated with incubator 2, described incubator 2 tops are provided with coupled logical negative incubator 7, and described blast pipe 6 is connected with negative incubator 7; The horizontal plane that is higher than water supply tank 1 and negative incubator 7 suitable for reading of blast pipe 6, the following mouth down of blast pipe 6.

As improvement, described blast pipe 6 can insert incubator 2 from incubator 2 bottoms and enter in the negative incubator 7.Described negative incubator 7 adopts metal materials to make, and is connected for a tooth between negative incubator 7 and the incubator 2.

Embodiment one: the negative incubator 7 of the utility model adopts stainless steel to be made, heat-insulation layer in it is identical with main water box, blast pipe 6 directly inserts incubator 2 from incubator 2 bottoms and enters in the negative incubator 7, and it is suitable for reading to be lower than negative incubator 7 wall of inner container 2cm and to get final product.Be connected for a tooth between negative incubator 7 and the incubator 2.Adopt structure of the present utility model, the comparable regular solar water heater of temperature retention time prolongs about 50%, and it is about 30% that the thermal efficiency can improve, and anti-freezing property can improve 30-40%, and the life-span of water heater is prolonged.
