Description

Steam transmitted type electric steam iron and do not have the sealed steam generator

The present invention relates to a kind ofly mainly spin electroheating type steam generating iron and a kind of auxiliary steam generator that also can be used for other field that industry is used in family or clothes pin.

Existing electroheating type steam generating iron utilizes the heat of accumulation of heat base plate to make water vapor, and existing doing scalded function, possesses spray vapour function again, or adds spraying function in addition.But its evaporating capacity is subjected to the restriction of accumulation of heat baseplate temp, and is lower as the required ironing temperature of dress material, is prone to a large amount of globules or evaporating capacity and descends significantly; Water directly splashes into vaporizer and easily produces and can cause and block and sordid incrustation scale; Water tank is because of the restricted installation of water of volume is little, adds to discharge water also inconveniently, and water is difficult for putting clean and the unhygienic and electrical equipment of collection is made moist in the water tank; Manufacturing technique is complicated in addition, and cost is higher, and service life is also shorter.

One of purpose of the present invention provides a kind of evaporating capacity and not limited by the accumulation of heat baseplate temp; Once adorn water many, add and discharge water conveniently; Collect convenient and healthy; Be difficult for producing incrustation scale; Manufacturing technique is simple, and cost is low, and the electroheating type steam generating iron that scalds, sprays vapour, cold nebulization function is well done in having that the life-span is long.

Another object of the present invention is for number provides kind of an accessories apparatus like necessarily counting the electric iron that has had in the family, have the electroheating type steam generating iron that electric iron has good flatiron effect instead.

The present invention is that following mode is finished: set up admission passage and jetted hole in the accumulation of heat base plate of electric iron, or on existing iron plate, add a steam jetting plate or a steam jet head that has admission passage and jetted hole, the end that the other end connects the steam transmitting pipe of steam generator inserts the air inlet pipe joint and then becomes the electroheating type steam generating iron, does not insert or steam generator is not worked and then kept original electric iron function constant.

The nothing of supporting design sealing steam generator is covered with a cup-like cover or sheet by water heater to be formed, it is characterized in that adding a cover back device inner chamber and do not form a sealed space, be to rely on open bore and other packing less positions on the air pressure setting-out closing cap to prevent vapour leakage, the air pressure of this device changes along with the air pressure of the actual needs of flatiron, general hyperbar is pressed high value at the about 500mm water column of 5000Pa(height than ambient atmosphere) below, but the air pressure that can satisfy supporting iron arrangement has required.

Specifically: keeping under the constant condition of existing electric iron accumulation of heat base plate appearance and size, the mode of setting up admission passage and jetted hole has three kinds, the one, be suitable for the casting of cast iron and aluminum alloy materials, steam inlet pipe directly is cast in the accumulation of heat base plate, and is drilled with jetted hole in the end portion of this pipe; The 2nd, be suitable for the assembling method of steel plate and cast iron materials, the steam jet head and the steam inlet pipe of packing into and having jetted hole; The 3rd, be applicable to the casting die of aluminium alloy, divide top panel and lower plate two partly, directly cast out admission passage and jetted hole.

As the remodeling method to existing electric iron in user's hand is to increase a kind of annex, is folding the additional steam jetting plate of aluminium matter that a kind of thickness is about 4～6mm, the similar above-mentioned casting die of its manufacture method on the accumulation of heat base plate.Also can be at rear portion or anterior additional a kind of steam jet head of flatiron.The former can heighten a little energy to the temperature adjustment temperature slightly and obtain the effect mutually few with the overall improvement type, because aluminium matter is conducted heat fast, do not influence original the doing of electric iron yet and scald effect, the latter is simple in structure, cost is low, but the steam jet head of this band jetted hole must have the drainage function, has a spot of condensate water because the thermolysis of steam transmitting pipe reaches the steam of air intake, with finishing the back water is bled off.Adapter is fixed on the electric iron with bolt or magnetic force or spring clip.

The a small amount of condensed water in high temperature that has in the thermolysis steam because of steam transmitting pipe will be vaporized in steam inlet pipe or admission passage again.So steam inlet pipe or admission passage should be tried one's best near heating element heater, heating surface area should be tried one's best greatly, certainly will be under the rational condition of size, the heat-insulating property of steam transmitting pipe also should be quite a lot of as far as possible, guarantee vaporization fully under a little higher than water boiling point temperature of electric iron like this, can very fast evaporation do when but the minute quantity condensed water in high temperature arrives dress material, can not influence the flatiron effect, guarantee vaporization fully about the water boiling point temperature, also can between steam transmitting pipe and air intake, connect a water filter and earlier condensate water be filtered out.

In the ironing temperature about 60～90 ℃, the thermosistor of electric iron is difficult to connect, because in fact the heat effect of steam forms the structure of similar pressure decatizing Steam iron.Yet steam channel is very little after all, the actual temperature of accumulation of heat base plate is relevant with steam flux, show according to sampling, though condensate water increases, promptly confuse steam and formed the cold nebulization function, pull out in fact that steam transmitting pipe is aimed at the place that will spray and the spraying function of existing electroheating type steam generating iron also is identical from jetted hole ejection.

It is the basic function of steam generator that superpressure discharging, water-level alarm and pressure show, covers the very light simple device of forming with water heater by cup-like cover or sheet and also possesses above-mentioned functions.Cup-like cover is divided gravity-type and is clamped two kinds on type, profile is that the bottom is provided with the downward opening cup-shaped device of opening port, also indicate maximum installation of water mark, go up the steam discharge formula if be, venthole is arranged in addition at top, the maximum secting area of cup-like cover lacks about 5～30% than the water heater sectional area, so the gravity-type cup-like cover only need be placed in the water heater just, the type that clamps is then wanted stubborn being stuck in the water heater, the sheet lid also has gravity-type and clamps two kinds on type, they are different with existing steam generator is the water-level alarm pipe that is equipped with the open bore similar functions, inner chamber does not form hermetically-sealed construction yet, gravity-type and the branch that clamps type are gravity-type cost height, but convenient water heater that can supporting non-specificity.

Air pressure increases in cup-like cover, water from opening port, be pressed onto the lid outside cause covering interior decline of water table, covering outer water level rises, when reaching, air pressure then formed balance when satisfying the flatiron needs, when occurring as improper phenomenons such as steam transmitting pipe obstructions, steam will discharge from open bore, the general weight of gravity-type is referred to as floating type less than its maximum displacement, cup-shaped lid will float and enlarge the vapour passage to prevent too fierceness of water boiling, shield also has the too drastic effect of seething with excitement of anti-sealing, in case the vapour road is unimpeded, the gravity-type cup-shaped lid can automatically reset, yet the type that clamps then will rely on bigger open bore, so the maximum installation of water of device should not surpass the water heater capacity half.The superpressure row of sheet lid sends out will be on sealing place or the safety valve of setting up.

The water-level alarm principle of cup-like cover is that the vaporization along with water causes decline of water table, decline of water table has arrived the position of open bore in lid, can cause under the not high condition of water level that outside lid open bore lets out vapour, but also keep certain water level outside the lid, blow the underwater sound with regard to having formed stronger steam discharge like this, and along with the decline steam discharge sound of water level is strong more, that listens is very clear in the scope of number Mi Yuan, cause device steam bleeding voluntarily at last, flatiron does not have vapour.What begin to report to the police for remaining the water yield in the capacity, main relevant with position, size and the quantity of open bore, generally also can keep the water yield about 10 minutes with the maximum heating power calculation, allow the operator have time enough to handle, the alarm principle of sheet lid is that some decline of water tables can cause steam bleeding voluntarily to the water-level alarm pipe, loud steam discharge also can take place during beginning blow the underwater sound.

The cup-shaped lid lid outer water level operator can see intuitively, though this water level does not reflect the actual water level in the lid, can allow the people that air pressure is had generally and understand.The water level that descends inside and outside covering because of water temperature when adding water is identical, can add water according to the mark that covers like this, does not need to uncap so add water.Unless the sheet lid is made the water-level alarm pipe with transparent material, otherwise is difficult to see barometric information, adds water and generally will uncap.

According to the actual requirement of flatiron, steam supply should have the keying function, and the vapour amount preferably also can be regulated, and because of air feed air pressure is very low, generally takes directly to open and close the method for the power supply of heating element heater.Use cup-shaped lid to close in addition and open the source of the gas sensitive characteristics, reason is that the outer water of lid will be lower than boiling temperature because of the thermolysis actual temperature, and the coolant-temperature gage on upper strata is low more, almost cannot see steam when heating on the container and rise, when high-power heating, can see having a small amount of steam to rise slowly with small-power.Cause air pressure to descend in case power supply disconnects, cover outer water promptly by dashing in the opening port, heating element heater surface heat promptly is absorbed, and flatiron has also just been cut steam.The heating element heater internal heat spreads out of and can keep certain evaporating capacity and be incubated a period of time, recovers vapour in case connect power supply at once.It is bigger to use the sheet lid then to open and close vapour source inertia, needs to use the less heating element heaters such as electrothermal tube of thermal capacity.The best approach of evaporating capacity control yes stepless power adjuster also can be installed the evaporation capacity for engine adjuster and arrange voluntarily by steam generator and send out a part, and another kind of simple, practical, method for saving energy is half a guiding element diode in parallel, and heating power is made into two-stage.With one-level power is that 300～400W calculates, and about about 10～12 gram/minute of evaporating capacity, secondary power is 75W～100W, about 2～3 gram/minute of evaporating capacity.It is also little that secondary power no longer cuts off influence, but the double as heat insulation function.Gauge tap preferably is installed on the flatiron, also can directly be connected on the wire and plug or put table to go up for using, and can only be back two kinds as transformation as existing flatiron.

On probation showing per sample, the air pressure of flatiron body actual needs is mainly relevant with evaporating capacity and air port footpath, and and the heat-insulating property of appendix also has relation, particularly as when the professional use, to hang height to appendix and be convenient to operation, the spontaneous current that has so just formed vertical pipeline section condensate water to steam flow on the contrary, equal the steam transmitting pipe internal diameter like this and diminished, serious like this meeting causes blows water noise, so the best outsourcing cotton yarn of steam transmitting pipe suitably increases the internal diameter of vertical pipeline section.General steam transmitting pipe internal diameter is about 5～6mm, and by the reasonable size requirement, the normal air pressure that uses is about 500Pa.But higher as the air feed pressure, adjustable size improves the normal air pressure that uses.

Above-mentionedly show that the advantage of cup-like cover is obvious, the Package size of cup-like cover is also very desirable in addition, the water-level alarm pipe of sheet lid will be divided into that can to assemble several sections packing ratios better, but the advantage of sheet lid is that installation of water is big, and can obtain higher air pressure, and cup-like cover generally can only obtain the following air pressure of 2000Pa, otherwise volume is just unreasonable.

It is very feasible that a kind of domestic electric heating cup and supporting simplified way of gravity-type cup-like cover of directly taking common 1 liter of capacity arranged, obtainable maximum gas pressure is about 1000Pa, about once maximum installation of water 500 grams, can use more than 1 hour continuously, characteristics according to above-mentioned cup-like cover, can not influence result of use in electric cup internal diameter error 5～10mm scope, the cup-like cover of a special use can be supporting with the electric cup of 1 liter of capacity of any non-special use, use also very light, electric cup is put on the table, cup-like cover is put into, preferably steam transmitting pipe passes the handle of electric cup earlier, insert the air intake of flatiron again, in any case electric cup does not have the plug of the possible electric cup of overturning to insert on the subsidiary socket like this.With finishing cup-like cover is taken out opening up, steam transmitting pipe down, the very fast meeting of the evaporation of waste heat is totally anhydrous.Packing of product size like this is also very desirable, the high about 100mm of cup-like cover, and the about 100m of major diameter, heavily about 400 grams～500 grams are as long as it is just passable that lengthening 1/3 is closed in the original packing of electric iron.The family that does not purchase electric cup as yet can make electric iron temporarily and use, in fact the only a little higher than electric iron of its price.

Well-known steam generator can go out vapour after will arriving the water boiling, adding hot water can shorten and give the hot time, particularly family's available heat water bottle directly adds hot water, because the filler is very big, the electric furnace formula electric cup big with thermal capacity is example, according to survey is to add 500 gram hot water to give the hot time be about 5 minutes, also lead over the hot time of giving of electric iron slightly, adding water once more preferably also is hot water, can recover vapour after general half a minute, can not influence its continuity, give the hot time and will grow, do and scald function but do not influence it yet add cold water.

This device roughly can divide four kinds of luxurious functional forms, integrated-type, basic model, additive type, back three kinds be actually before a kind of reduced form.Integrated-type is to adopt to clamp type dedicated water heater and be integrated on the substrate, self-organizing system, and power transmission line and steam transmitting pipe can lump together.Belong to high-grade luxurious functional form and take the stepless power adjuster auto-power-off device of cutting off the water supply.Following steam discharge formulas etc. preferably have transmission of electricity, the self-jacked function of vapour spool.Basic model then is the separate type of above-mentioned use electric cup, and additive type is to add steam jetting plate or the existing electric iron adapter of steam jet head conduct on the basis of basic model.

On probation showing per sample, this device has following advantage: the vaporization effect that (1) is good, have spraying function concurrently, and evaporating capacity is not subjected to the restriction of ironing temperature, especially the lower dress material of required ironing temperature is had that speed is fast, the measured effect of matter.(2) cost is low, reduced investment, and technology is simple, and easily reaches designing requirement.Only high by about 20% than electric iron as its cost of basic model, electric iron manufactory need not technological transformation and just can produce.(3) add the convenience that discharges water, amount of water is big.So because of reaching the flatiron body is that steam is difficult for producing incrustation scale.(4) can be no seal also without binding agent, have distortion also not influence result of use, so long service life.Part is also very convenient in addition for maintain and replace.(5) there is electric iron to add the design feature of annex, need not to take out annex when scalding, keep electric iron flexible, the characteristic that quality weight power is big as doing.
