Description
Technical field
The utility model belongs to electric heater unit technical field, is specifically related to a kind of warm water heater not producing incrustation scale.
Background technology
In the process of water heating, after the mineral matter in water etc. are heated, can incrustation scale be produced, because heating rod surface temperature is relatively high, make incrustation scale in heating rod surface condensation; This can make the impact of bad one-tenth to heating rod; Cause heating rod low for service life, in pipeline, produce water pollutions.
At some special occasions, as Temperature controlling water bed etc., its water temperature used usually can not more than 60 DEG C, but it is in the process heated water, near heating rod, temperature is still very high, can reach 100 DEG C, therefore, cause heating rod surface or fouling can not be avoided and cause water pollutions.
In addition, also there is certain infringement for heating rod itself in high temperature; Determine through experiment, when using common water source, after heating rod uses 200 hours, heating rod surface there will be black scale, has a strong impact on heating rod service life (service life is only 1000 hours); If use pure water, heating rod continuous operation is after 200 hours, although there is not obvious scale formation, heating rod surface still can due to high temperature blackening, and service life decreases.
Publication number is CN203731688, title is in the patent application of " a kind of hot-water heating system preventing incrustation scale from generating ", it discloses a kind of warm water heater, and it arranges jet water spout in heating rod side, carries out spray cooling by the flushing hole on jet water spout to heating rod.Although this heater can reduce heater surface temperatures in theory, realize not incrusted object, in actual applications, there is very large problem, 1, the height of flushing hole size and hydraulic pressure coordinates requirement; 2, flushing hole arrangement uniformity requirements is high; 3, flushing hole is more, requires that the water-aspirator pressure coordinated with it is larger.Therefore, above-mentioned heater processing difficulties, after machining, if do not tested, is difficult to ensure heating rod not scaling completely, therefore, causes this product to be difficult to put goods on the market.
Publication number is CN202928111, title is in the patent application of " a kind of liquid heater ", it discloses a kind of liquid heating, it arranges conducting element by the water inlet end at heat-generating pipe, conducting element is round sheet, and distribute pod apertures ringwise, it forms the current rotated by annular pod apertures, thus it is more even that heat-generating pipe is dispelled the heat.Through the test of applicant, above-mentioned heater is carrying out in the process heated, current are through pod apertures, the current of rotation can formed at first, but to the rear portion of heating tube, current can't the appearance shown in the accompanying drawing of above-mentioned application documents rotate, and can form the dead angle that current do not pass through, thus produce a large amount of incrustation scale at the rear portion of heater; Therefore, above-mentioned application documents are only designs, and it can not practical application, and it does not reach the effect of non-scaling yet.
Summary of the invention
The utility model is exactly for the problems referred to above, provides a kind of structure simple, the whole surface temperature of heating rod can be made to reduce, can not produce incrustation scale, the warm water heater low to hydraulic demand.
For realizing above-mentioned purpose of the present utility model, the utility model adopts following technical scheme, the utility model comprises heating rod, it is characterized in that: heating rod is outside equipped with sleeve, one end of sleeve is closed, and the other end is for open, and one end of sleeve closes is provided with water inlet, sleeve lining is provided with guiding helicoid, between described guiding helicoid and heating rod, is provided with gap.
As a kind of preferred version of the present utility model, described water inlet eccentric setting.
As another kind of preferred version of the present utility model, described sleeve is outside equipped with water jacket, and described water inlet is provided with the water inlet pipe stretching out water jacket, and described water jacket is provided with outlet pipe.
Further, described barrel end top is provided with steam vent.
Further, described water jacket surface is provided with blast pipe corresponding to steam vent.
The beneficial effects of the utility model: 1, the utility model is by arranging guiding helicoid, after current enter sleeve, under the positive action of guiding helicoid, current form helical form and form current spiral around heating rod, and between guiding helicoid and heating rod, gap is set, current are fully contacted with heating rod, utilizes the water at low temperature (backwater) of water inlet, make heating rod fast cooling; After measured, heating rod surface everywhere temperature all can remain on less than 60 DEG C, ensures that heating rod surface does not have high temperature, can not produce incrustation scale.
2, because the utility model adopts guiding helicoid to carry out pressure water conservancy diversion to current, therefore, hydraulic pressure can be controlled in less scope, and require low to pump power, being more suitable for being applied to some needs quiet occasion, as heat cycles water bed etc.
3, because the heat on heating rod surface can be taken away by helical form current of the present utility model fast, therefore, the efficiency of heating surface of heating rod can be improved.
4, the utility model is by water inlet eccentric setting, can ensureing that current are when entering sleeve, will produce helical form current, being conducive to the cooling of heating rod root.
5, the utility model is by arranging water jacket, is convenient to lower the temperature to sleeve, improves the efficiency of heating surface further.
6, the utility model is by arranging steam vent and blast pipe, can discharge in the utility model heating process a small amount of gas produced fast, ensures the utility model energy long-term stable operation, improves service life of the present utility model.
7, the utility model to be highly suitable for into water (backwater) temperature, lower than 60 DEG C, having the technical field of certain hydraulic pressure.
