Description

Steam can water heater

Technical field

The utility model relates to a kind of fluid heater, especially has the water heater of heat-generating device.

Background technology

Civilian and the commercial water heater of Xiao Shouing probably has several types in the market: i.e. gas heater, electric heater, solar water heater, air-source water heater, heat pump water heater etc.Although of a great variety, all be to adopt the technology of the nineties in last century to produce basically.Traditional electric heater all is to adopt electrothermal tube water directly to be heated ubiquity two big defectives: the one, and water power does not separate, and has potential safety hazard to some extent; The 2nd, at the bottom of the thermal efficiency, power consumption is big, and the electrothermal tube surface area is little, and the surface point temperature is too high, makes various mineral matters such as calcium in the water, magnesium, salt produce " incrustation scale " by electrolysis easily and is attached on the electrothermal tube tube wall, in the course of time, the thermal efficiency is reduced greatly.Whole water heater industry is compared with other field, aspect technological progress, relatively lag behind, the problem of its generality is to have potential safety hazard and the big cost height of operation energy consumption to some extent, a kind of not only safety but also energy-conservation technology are also being sought by water heater industry and related scientific research department in this objective fact of approval, but owing to have high input, difficulty is high and can't realize all the time.

The utility model content

The purpose of this utility model provides a kind of steam safe, energy-conservation and that the thermal efficiency is high can water heater.

In order to achieve this end, applicant organizational technology strength is tackled key problems, and through years of researches and repetition test, develops not only safety but also energy-conservation steam energy water heater finally.Its technical scheme is:

A kind of steam energy water heater, it comprises electrothermal tube and water chamber thereof, it is characterized in that also comprising:

Notes are in described water chamber and the pure water of submergence electrothermal tube;

The upper end is communicated with the vacuum condenser that the lower end is communicated with the lower end of water chamber by return duct with the upper end of described water chamber;

With the water filling/vacuum tube that is interlinked to the outside in the condenser.

The critical piece of steam energy water heater is the heating container, and this container is the cylindrical of closed, and the top is a semicircle, and its shell adopts metal material to make, and the bottom is provided with and comprises electrothermal tube and vacuum tube, fills pure water in the container as heat transfer medium.Wherein, vacuum tube is used for injecting pure water and vacuumize in container.When electrothermal tube when heating energising, the pure water in container boiling rapidly becomes high-temperature steam and is full of the entire container chamber, makes container outer wall form a high temperature heater, and this heater can heat the object around it, and fluid especially is as water and air etc.If the heating container is arranged in the storage tank, and the case inner cold water obtains heating up by the heat that absorbs the heater conduction just and becomes hot water.Meanwhile, high-temperature steam in the heating container is met the cold reduction of condensation at once becomes distilled water, be back to electrothermal tube by return duct, electrothermal tube heats it again and becomes high-temperature steam and be full of the actual arrival container chamber again, so through circulation repeatedly, make the water of storage tank constantly absorb vessel surface heat energy, temperature gets a promotion.The heating of air in like manner can push away.

Steam can adopt indirect by water heater, electricity separation, and than traditional electric heater, its security is fully guaranteed.Next adopts pure water as medium, and through deaeration in condenser, so the electrothermal tube tube wall can not produce " incrustation scale ", adds that the heating container surface area is big, and its thermal efficiency is apparently higher than traditional electric heater.Following advantage is specifically arranged:

(1) safety.Electric heater series products in the market is and adopts electrothermal tube directly to place water to heat, the shortcoming of this mode of heating maximum is to have potential safety hazard, statistics is complained in report according to the National Association of Consumers (NAS), since two thousand five, reach 3000 every year on average because of using electric heater (containing " immersion heater ") to be leaked electricity and injuring to complain.And steam can adopt the indirect mode by water heater, and water power separates fully, so the potential safety hazard that does not exist electric leakage to bring.

(2) thermal efficiency height, energy-conservation.Steam energy water heater is owing to adopt high-temperature steam to conduct heat, and the surface area that adds upper container is more than tens of times of electrothermal tube area, so its thermal efficiency is self-evident.The contrast test of doing through technical supervision department, all technical indicators of steam energy water heater all are better than present national standard, as contrasting with heat pump water heater under the contrast condition, the efficiency of heating surface of heat pump water heater is 89%, and the efficiency of heating surface of steam energy water heater is 99.6%.

(3) green, environmental protection.Because steam can water heater is not had motor, the compressor-free operation, so noiselessness no anyly make agent and burn beyond the region of objective existence row, with respect to adopting compressor, the air-source water heater of freon, the key technical indexes such as hot water rate that goes out of steam energy water heater is better than the latter.
