Abstract

The iron has a steam inlet (11) connected to the changeover valve (12) which, by means of a control button (21) can direct the steam to the sole plate (4) and outlet holes (6,8) or to the spray nozzle (17) at the front of the sole plate.

Description

The The invention relates to a steam ironing system with a stationary one Steam generators and an iron connected to these according to the generic term of claim 1.

In conventional steam irons from a water tank integrated in the water water is dropped via a needle valve in a lying in the soleplate heated steam chamber, evaporated there, and passed through channels in the closed and heated soleplate as dry steam to exit holes on the bottom of the soleplate and there through them Outlet holes supplied to the ironing. To smoothen particularly persistent wrinkles or twists in the ironing material, the dry steam for moistening the textile fibers is not sufficient. To compensate for this disadvantage, most steam irons are equipped with a spray nozzle, which is arranged on the front of the iron and sucks by means of a push-button operated by hand mechanical pump water from the water tank and sprayed through the nozzle in front of the iron on the ironing ( DE 44 30 548 A1 . EP 0 497 470 A1 ). Subsequently, the iron is passed over this eingenässte batch while the water evaporates.

For irons that use an external steam generator, the water tank and steam generation are outside the actual iron. The steam is supplied via a hose to the iron ( EP 1 178 147 A2 . EP 0 342 302 A1 ). Due to the thermal conditions in the little thermally insulated supply hose, the dry steam cools down before it reaches the iron, something, and must be reheated in the iron again to escape as largely dry steam from the steam outlet holes in the soleplate of the iron can. A leakage as wet steam would have the disadvantage that larger condensed water droplets escape from the steam outlet holes of the soleplate, that they are not completely evaporated by the subsequently moving iron and thus no complete dehumidification of the ironing takes place or even water stains can remain. When moistening the material to be ironed with water through a spray nozzle, this danger does not exist, since only a fine mist of water hits the material to be ironed through the nozzle, which can subsequently be vaporized easily and also leaves no water stains.

Accordingly, in steam irons with an external steam generator, which do not have their own water reservoir, in the iron incoming wet steam is supplied as needed by means of a manual switch via a switching valve of the spray nozzle ( EP 0 999 303 A2 ).

at conventional steam iron are arranged on the front of the iron spray nozzles constructive reasons relatively high on the iron and thus high above arranged the ironing. Leading to a relatively wide spray, the usually wider than the problem zone of the ironing material to be moistened is.

Also is often undesirably far due to the high arrangement of the spray nozzle sprayed in front of the iron. experienced It is therefore the practice of the operators to use the iron for the spray process take off, the iron diagonally across the Problem zone to hold and spray them directly.

at Iron with external steam generator, it is possible because no water tank or Water supply system to the steam chamber is present, the spray nozzle is relatively low at the front of the iron to place. This allows the problem zone to be immediate and targeted in front of the iron be moistened.

More particularly, in such a known steam ironing system of the type mentioned in the introduction, an inside hollow metal plate which forms an iron soleplate at the bottom, steam outlet holes in a front soleplate zone, and also at a front end of the plate further steam outlet holes representing wet steam spray nozzles, since they wet steam in spray an area in front of the sole of the iron ( EP 0 999 303 A2 ). With the wet steam spray nozzle or nozzles areas of the laundry to be ironed are to be achieved, which are difficult or impossible to reach with the steam outlet holes in the sole by the sole is lifted from the laundry and directed to the part to be moistened the laundry. This process is cumbersome and tedious and tiring when - as is typical for such steam ironing systems - a lot of laundry should be ironed over a long period of time. - To activate with the iron of this steam ironing system alternatively the steam spraying before the sole region of the iron or the usual steam outlet from the steam outlet holes in the sole, on the one hand the steam outlet holes in the sole via a steam chamber connected to the switching valve and on the other hand, the wet steam spray nozzle (s) connected via a line to the switching valve whose input communicates via a hose with the stationary steam generator. The change-over valve may be switched by an operating knob, for example, disposed in the handle of the iron to actuate a contact in a circuit to the switching valve. The switching valve is designed so that it depends on the Kon clocking the steam supplied to it - wet steam - either the steam chamber only through the steam outlet holes in the front part of the sole supplies, or the area before the sole sprayed wet steam nozzle. A disadvantage of this steam ironing system, inter alia, that the steam that reaches the iron from the steam generator via the steam supply line, in which it cools, as wet steam leaves the steam outlet holes in the soleplate in the corresponding position of the changeover valve as wet steam, since the steam chamber he flows through it, no additional heat is supplied. An optimal ironing result is thus not achieved, not even if additionally wet steam is sprayed at relatively high temperature from the wet steam spray nozzle.

The prior art also includes an electric iron with a spray nozzle, which is arranged in an upper region of the iron in front of the handle and directed forward down below, and with a water tank from which water can be fed into the spray nozzle ( EP 0 497 470 A1 ). The iron further comprises a steam chamber formed as a steam generating chamber in the electrically heated sole plate and communicating with steam exit holes in the sole. The water supply to the steam chamber is adjusted by a rotary valve adjusting valve disposed between the water tank and the steam chamber. The iron further comprises a knob that can be both rotated and pressed and cooperates with a valve and pump element. By turning the control knob can be selected whether water is supplied to the spray nozzle or the steam chamber to generate a steam pulse by appropriate water supply. In both rotary settings of the operating knob this can be depressed to each pump a water surge in the spray nozzle or the steam chamber. With this iron, however, the benefits of a steam ironing system with an external stationary steam generator can not be achieved. - Apart from this, the pumping the ironing material only briefly increased moisture and / or heat supplied to improve the ironing result. On the other hand, if the system or the ironing station were dimensioned for the continuous delivery of larger amounts of steam, this increased the manufacturing and energy costs.

In order to achieve with a steam ironing system with a stationary steam generator and an iron connected thereto an alternatively increased steaming of the critical ironing material for improved ironing results over a longer period, without requiring more powerful more complex steam generators, it is already known, a heated sole in one rear sole region with a number of steam outlet holes and a front sole region with the remaining steam outlet holes to divide and to arrange between the subset of the steam outlet holes in the rear sole region and the steam generator, a switchable Dampfreduzier- / locking device over which the Teilmengedampfaustrittslöcher in a first switching position in maximum steam line tender Connection with the steam generator and in a second switching position at most reduced in steam-conducting connection, the remaining steam outlet holes in both switch positions with the steam generator in vapor-conducting connection ( EP 1 178 147 A2 ). Specifically, the switchable steam reducing / blocking device has a switching element which can be actuated directly on the iron from the outside, as well as a steam inlet nozzle and at least one steam outlet nozzle. - However, a wet steam spray nozzle is missing for problem areas of the ironing stock.

Furthermore, a steam iron with a liquid container, a heated shoe and a sole provided with steam outlet holes is known, which has a first evaporator chamber, which communicates with the steam outlet holes, and a second evaporator chamber, which leads to a steam outlet nozzle at a tip of the Iron is in fluid communication ( DE 44 30 548 A1 ). The second evaporator chamber has two Zutropfstellen, which are arranged at different distances from the steam outlet nozzle. By adjusting a distributor device with which the liquid supply is adjusted to the two dropping points, essentially only a first partial stream of liquid can be supplied to the first, removed Zutropfstelle, thus virtually completely evaporated up to the steam outlet and as a relatively hot steam on the ironing or a second partial stream of liquid can be added dropwise (in addition) to the second dropping point adjacent to the outlet of the steam outlet, so that a less hot vapor-liquid stream, which is strongly enriched with liquid droplets, strikes the item to be ironed. This should take into account the nature of the material to be ironed. For example, synthetic fabric that is non-absorbent may be affected by wet steam with water stains, or the steam may not adequately penetrate a thick, absorbent natural fiber such as cotton so that it would need to be moistened and ironed multiple times. For supplying the liquid to the first dropping point, which is only in fluid communication with the first evaporating chamber, and to the first and optionally second dropping point of the second evaporating chamber, a pump operable with an actuating element, whose flow rate can be adjusted, is used. However, the delivery rate and distribution of the first and second fluids are sigkeitsteilstroms the second evaporator chamber depending on the ironing not easy to set properly. In addition, the steam iron is not intended for connection to an external stationary steam generator.

Of the present invention is based on the object, while avoiding the disadvantages of prior art steam ironing this form so that with uncomplicated adjustability, namely easy switching between wet steam spraying with a wet steam spray nozzle or steam through steam outlet holes in the sole even when not from the ironing material lifted iron a scorching or shine ironing is prevented.

These Task is for a steam ironing system of the aforementioned type according to the characterizing part of claim 1 solved by a vapor bypass, the between a steam inlet a switching valve used for the aforementioned switching and a first steam outlet of this switching valve so arranged is that the Steam vents in the sole of the iron at each switching position of the switching valve with at least one small subset of the steam introduced into the steam inlet acted upon become.

The small subset is in particular according to claim 3 10 - 20% of vapor introduced into the steam inlet, in any case less than the half the steam introduced into the steam inlet.

The inventive solution draws characterized by a low design effort. Especially can be the vapor bypass between the steam inlet and the first steam outlet the switching valve be realized in that this the steam inlet not completely shuts off from the first steam outlet when it is to the second steam outlet open is. It is therefore not an absolutely sealing precision changeover valve required. required but is that the steam outlet from the wet steam spray nozzle is completely blocked, when the switching valve is a switching position for passing the Steam from the stationary Steam generator occupies the first steam outlet, preferably over the Steam post-heating to the steam outlet holes in the sole leads.

Prefers has the iron, which to the steam ironing system with a stationary steam generator belongs to the aforementioned type, according to claim 2, a steam Nachheizzone, which is arranged so that the steam outlet openings in the sole of the Steam Nachheizzone with at least the subset of the in the steam inlet introduced steam are applied. This is done by dry ironing the previously sprayed with the wet steam material to be ironed a particularly good ironing result despite the small subset dry steam reached which the sole of the iron through the steam exit holes leaves.

As a general rule It is advantageous if the the iron in the steam ironing system from the stationary Steam generator supplied Steam that cools in the steam line and partially condenses and therefore hereinafter referred to as wet steam, in the steam Nachheizzone of the iron is heated to dry as steam from the steam outlet openings to escape the sole and then a good ironing result reach in the switching position of the switching valve, in the the ironed exclusively by the steam outlet holes steam is applied in the sole.

The Steam Nachheizzone is appropriate according to claim 6 realized by a heated steam chamber. This can in particular according to claim 7 at least one electric heating element are used, which also with the sole of the iron thermally conductive connected is. For this it is advantageous in an iron foot from good heat-conducting Material arranged, from which the steam chamber is formed and which forms or carries the sole down. This will be the effort kept low to produce the dry steam. The heated steam chamber can flow one or several steam chambers, which are the sole of the iron with the steam outlet holes adjoin and serve for steam distribution.

In order to achieve improved steaming of the critical ironing material from the sole of the iron during normal steam ironing without active Nassdampfspraydüse over a longer period without powerful, more complex steam generators, an iron is used in the steam ironing system according to claim 4, the sole in a rear soleplate zone a subset of the total present in the sole steam outlet holes, the remaining steam outlet holes are arranged in the front soleplate zone. Furthermore, in the iron between the first steam outlet of the switching valve and the subset of the steam outlet holes, a switchable steam reducing / blocking device is arranged, via which these steam outlet holes are in a first switching position of the steam reducing / blocking device in vapor-conducting connection with the steam generator, whereas in a second Switching position of the steam-reducing / blocking device possibly only in a reduced vapor-conducting connection with the steam generator are. The remaining steam outlet holes, which are arranged in the front soleplate zone, are acted upon in both switching positions of the steam reducing / blocking device from the first steam outlet of the changeover valve and the steam bypass with steam. This ensures that in the first position of the switchable Dampfreduzier / blocking device, the steam exiting from the steam outlet of the changeover valve is divided evenly on the subset of steam outlet holes in the rear soleplate zone and the remaining steam outlet holes in the front soleplate zone, while in the second switch position of steam reducing / Blocking device because of the reduced steam supply to the subset of steam outlet holes in the rear soleplate zone, the majority of the steam is supplied to the remaining steam outlet holes, which are arranged in the front soleplate zone.

Corresponding Claim 5 are preferred in the second switching position only to about 20% of the steam from the steam outlet of the diverter valve the subset of steam exit holes in the back soleplate zone forwarded and the predominant remaining part of the steam, so about 80% of the remaining steam outlet holes in the front of their soleplate zone. - The breakdown So always refers to the amount of steam that the steam outlet of the upstream switching valve, i. in a first switching position the switching valve, the entire steam inlet and its supplied steam in a second position of the changeover valve, only the small subset the steam introduced into the steam inlet of the switching valve, while the bulk of this steam is sprayed from the wet steam spray nozzle becomes.

By doing the switchable steam reducing / blocking device directly from the outside on the iron actuated first switching element and one with the first steam outlet of the Switching valve has associated steam inlet can the steam reducing / blocking device are made compact, so that she in the iron only little space claimed. Furthermore it is so comfortable even when ironing to press.

The switchable steam reducing / blocking device can according to claim 9 are completed to a compact and easily assembled component, by connecting one with the subset of steam exit holes first steam outlet and having a second steam outlet, the one with the rest Steam outlet holes connected is, and in that the first steam outlet and the second steam outlet of a Chamber of Dampfreduzier / locking device are led out, the in the first switching position to the first steam outlet and the second steam outlet is open, and in the second switching position to the second vapor outlet is open and only reduced to the first Steam outlet is open. The reduced opening to the first steam outlet represents the vapor bypass.

In order to the steam bypass is easy to install in formed the changeover valve.

Especially but compact and easy to use is the overall arrangement of the switching valve and the switchable steam reducing / blocking device according to claim 11 in that the Changeover valve and the switchable steam reduction / blocking device to a dual function valve assembly integrated with a housing and that the dual function valve assembly is only one of Outside directly on the iron actuated Has rotary pushbutton as a combined actuator. Advantageous it is that not two components, namely the changeover valve and the switchable steam reducing / blocking device each with an actuating element must be mounted separately and that at least one external line between the switching valve and the switchable Dampfreduzier / Sperrvor- direction omitted can. In operation, the operation is simplified because during the ironing only the one combined actuator in If necessary, the ironing person is not between two actuators needs to be different to operate the selected element.

More In detail, the integration of the switching valve and the switchable Steam reducing / blocking device to the double function valve assembly with the housing realized with the features specified in claim 12. Despite the Dual function, this double function valve assembly is straightforward can be produced with just a few elements. Three different functions of the iron can through the only combined actuator manifest be set, namely a first function with untwisted and depressed rotary pushbutton when only dry steam evenly the sole of the iron stream should, a second function with turned depressed rotary pushbutton, in the reinforced Peak steam for a long time from a front soleplate zone flows while only little dry steam needs to flow out of the rear soleplate zone, and a third function when the rotary push-button is pressed, regardless of whether this is rotated or not, to wet steam from a front the iron arranged wet steam spray nozzle on the ironing too spray and still some dry steam as top steam from the front soleplate zone to let escape.

According to claim 12, the double comprises functional valve assembly with which these functions are adjustable, essentially only three components, namely except the housing a rotary valve and a plunger slide, which can be set together in the housing in one of two rotational positions to activate the first or the second function. Independently of the rotational position, the immersion slide in the rotary valve can also be lowered from its spring-loaded rest position by depressing the combined actuating element in order to trigger the third function.

For this constructive in detail is the dive slider according to claim 13 formed substantially as a cylinder, which in the rotary valve opposite the force of a spring is vertically displaceable, and the rotary valve, which is formed substantially as a hollow cylinder, and the Diving sliders are by means of a driving nose of the rotary valve and one of these receiving entrainment of the plunger slider against each other non-rotatable but slidably connected.

Of the Wet steam bypass, over a small subset of the wet steam flowing into the dual function valve assembly After heating in a steam Nachheizzone the front soleplate zone supplied will if the iron for wet steam spray operation works properly, according to claim 14 as a wet steam bypass flow moderately between the wet steam inlet and the first wet steam outlet in the dual function valve assembly be formed.

space saving and structurally uncomplicated is the wet steam bypass according to claim 15 with depressed Diving slider in the form of a reduced opening of the wet steam inlet to the first wet steam outlet of the housing between an outer peripheral contour the plunger slider and an inner peripheral contour of the rotary valve educated.

Of the Rotary valve serves on the one hand in conjunction with the plunger slide for switching the wet steam to the wet steam spray nozzle and the other for distributing the dry steam formed by wet steam by reheating to emanate from the front and rear sole soles in given relations and he guarantees in connection with the dipping slider the escape of a small subset of dry steam from the front soleplate zone as peak steam when the wet steam spray nozzle is activated.

To the Controlling the wet steam is according to claim 16 provided that in the rotary valve a rotary slide wet steam inlet is formed in each rotational position of the rotary valve with the wet steam inlet of the housing is connected in that in the rotary valve, a first rotary vane wet steam outlet is formed in each rotational position of the rotary valve with is connected to the first wet steam outlet of the housing and pressed with a dive slider on a Tauchschiebernassdampfkammer and formed in the rotary valve second rotary vane wet steam outlet with the second wet steam outlet of the housing in fluid communication stands.

Farther are for controlling the dry steam to the rear soleplate zone, which is connected to the first dry steam outlet, or to the front soleplate zone, which communicates with the second dry steam outlet of the housing, the Features of the rotary valve according to the characterizing Part of claim 17 provided. This will be two in particular options or functions of the distribution of the dry steam when switched off Nassdampfspraydüse controlled.

Around the wished Outlet of peak steam to a reduced extent with activated wet steam spray to independently effect, the rotary valve continues to have the in the characterizing part of claim 18 specified characteristics. This will ensure that at active wet steam spray nozzle these 80 - 90 % of wet steam entering the dual function valve assembly as wet steam spray releases while the remaining 10 - 20 % after reheating as dry steam from the steam outlet holes of the front soleplate zone escape.

in the individual are to the inlets and outlets in the rotary valve according to claim 19 arranged, resulting in a compact production-favorable Rotary valve leads.

The above specified relation of the wet steam spray exit from the Wet steam spray nozzle too The dry steam outlet from the front soleplate zone is reduced by reducing the steam flow rate to the second dry steam outlet first through the wet steam bypass and then through the dry steam bypass in the Doppelfunktionsventilbaueinheit achieved according to claim 20.

Around the relations of the wet steam spray output to the dry steam exit from the front soleplate zone independently to achieve from the rotary valve rotation, are the most straightforward constructive features of claim 21 provided.

The plunger slider is according to a structurally simple apparent solution according to claim 22 substantially in a Tauchschiebertrocken steam chamber and subdivided into a Tauchschiebernassdampfkammer, each equipped with inlets and outlets for controlling the dry steam and the wet steam. The Tauchschiebernassdampfkammer is applied via a Tauchschiebernaßdampfeinlaß with wet steam and the Tauchschiebertrockendampfkammer receives dry steam through the Tauchschiebertrockendampfeinlass from the steam Nachheizzone outside the Nassdampfsprayventilbaueinheit. Manufacturing technology even cheaper instead of the Tauchschiebertrockendampfkammer and the Tauchschiebernassdampfkammer corresponding holes can be formed from the plunger slide, which occupy a smaller volume compared to the chambers.

Matching elements of the first embodiment according to the 1 to 3 and the second embodiment according to the 6 to 12 are provided with the same reference numerals.

In 1 includes an iron housing 1 an afterheater 2 , which is designed as an iron foot and a steam Nachheizzone 3 includes. The iron foot stands with a sole 4 in thermally conductive connection.

From the afterheater 2 is a steam distribution chamber 5 for a rear sole sole zone 4b formed, which is a subset of steam exit holes 6 includes, as well as a Dampfverteilkammer 7 for a front soleplate zone 4a with remaining steam outlet holes 8th for so-called top steam. In the Afterheater is inserted a heating element 9 to which an electrical supply line 10 leads. The heating element is thermally conductively connected to the reheating element.

In the iron housing 1 is except the electrical supply line 10 a wet steam supply 11 introduced, which is in communication with an external stationary steam generator, not shown.

The wet steam supply 11 leads to a switching valve 12 with an actuating mechanism 13 and a push button 14 in a button-leading 15 is slidably mounted.

On the output side, the switching valve 12 a first wet steam line 16 at a first steam outlet 16a on going to the steam post-heating zone 3 leads, and on the other hand to a wet steam spray nozzle 17 in the front upper area of the iron via a second wet steam line 18 at a second steam outlet 18a , The changeover valve 12 is directly outside the top of the iron actuated, in front of and above a non-designated handle.

In the same area is also a switchable steam reducing / blocking device 19 with an actuating mechanism 20 and a push button 21 operated in a pushbutton guide 22 is slidably mounted.

The switchable steam reducing / blocking device has a dry steam line on the input side 23 coming from the steam post-heating zone 3 led out, as well as the output side, a dry steam line 24 for the rear soleplate zone 4b and another dry steam line 25 for the front soleplate zone 4a ,

In operation of the steam ironing system with the described iron and the stationary external steam generator steam flows through the steam supply line 11 in the iron. As the steam in the steam supply partially condenses, it reaches the iron as wet steam. In the iron reheating of the wet steam takes place in the steam Nachheizzone 3 to allow dry steam from the soleplate 4 emanates, with a good ironing result is achieved.

On the other hand, problem areas of the ironing material to be moistened before the actual ironing process, in turn, to achieve a good ironing result. For this purpose, the in the changeover valve 12 inflowing wet steam in the 3 shown actuated position of the switching valve as such the wet steam spray nozzle 17 fed, which sprayed a moisture mist on the ironing. Since the wet steam still cools and condenses on exiting the wet steam nozzle, a sufficient humidification of the ironing material is achieved.

In this actuated position of the changeover valve 12 a small subset of the wet steam supplied to the switching valve is passed through the first wet steam line 16 the steam post-heating zone 3 fed. This is done by a steam bypass 12a in the switching valve or in this initial position only imperfect completing the first wet steam supply line 16 opposite the wet steam supply line 11 to the extent that 80 - 90% of the in the switching valve 12 incoming wet steam to the wet steam spray nozzle 17 is passed and only 10 - 20% of the wet steam through the first wet steam line 16 to the steam post-heating zone 3 and over these as well as via the steam reducing / blocking device 19 to the steam distribution chamber 7 for the front soleplate zone and to the steam distribution chamber 5 for the rear soleplate zone, of which the dry steam through the steam outlet holes 8th respectively. 6 subjected to the ironing. Specifically, since the switchable steam-reducing / blocking device is actuated, the proportion of wet steam flow of 10 - 20% as dry steam in about 80:20% on the front and the rear soleplate zone 4a respectively. 4b distributed as below too 2 is explained. So that scorching or shine is reliably prevented even when not lifted off the ironing iron.

In the in 1 illustrated starting position of the switching valve 12 on the other hand, the entire wet steam introduced into this is via the first wet steam line of the steam post-heating zone 3 fed, from the dry steam formed by reheating in the dry steam line 23 gets to the steam reducing / blocking device. In the drawn starting position of Dampfreduzier- / blocking device, this is so evenly over the dry steam lines 24 and 25 to the steam distribution chamber 5 for the rear soleplate zone 4b or the steam distribution chamber 7 for the front soleplate zone 4a opened, that the ironing material according to the number of Dampfaustrittslö cher 6 for the rear sole sole and 8th for the front soleplate zone evenly with dry steam is applied.

For special ironing tasks, the steam-reducing / blocking device 19 according to 2 operated, after which only a reduced amount of dry steam from the steam reducing / blocking device on the dry steam line 24 the steam distribution chamber 5 is fed to the rear soleplate zone, while the main part of the dry steam through the dry steam line 25 into the steam distribution chamber 7 for the front soleplate zone 4a flows. The ironing material is therefore essentially reinforced Peak steam applied. Specifically, the dry steam flow from the dry steam line 23 divided so that 80% of the dry steam in the front soleplate zone 4a and only about 20% of the dry steam is fed into the rear soleplate zone.

Thus, during normal ironing operation, the steam dry-lock device can be divided with the steam-barrier blocking device in such a way that it can be fed either into the front and the rear soleplate zones 4a . 4b , which are separated from each other, according to the number of steam outlet holes 8th respectively. 6 is divided, after which the ironing material is applied uniformly with dry steam, or the entire dry steam flow is divided so that about 80% reach the front soleplate zone and about 20% in the rear soleplate zone, ie above all peak steam is delivered.

If, however, only the switching valve is actuated, but not the steam-reducing / blocking device, then 80-90% of the wet steam flow, which in the switching valve 12 flows in, from the wet steam spray nozzle 17 sprayed and 10 - 20% of said wet steam flow through the steam Nachheizzone 3 evenly in the front and in the rear ironing zone 4b respectively. 4a directed. - This combination of the position of the switching valve 12 and the steam reducing / blocking device 19 is not shown in the drawing.

In a preferred embodiment of the invention according to the 4 to 12 For example, the switching valve and the switchable steam reducing / blocking device are a double-function valve assembly 27 summarized, via an operating mechanism 28 with a rotary pushbutton 29 can be operated. The rotary pushbutton 29 is in a rotary pushbutton guide 30 rotatably mounted and pressed down, see 4 ,

Based on 4 to 7 First, the assignment of four settings of the double-function valve assemblies 27 to four functions that can be exercised with the iron explained. Details of the dual function valve assembly, with which the functions are realized, will be with reference to the 8th to 12 explained.

In 4 the steam iron with the dual function valve assembly is shown in a first position in which the rotary push button 29 unconfirmed, that is neither rotated nor depressed from its initial position shown. In this first position of the dual-function valve assembly 27 is a wet steam feed from the wet steam feed line 11 from the steam generator to the second wet steam line 18 and the wet steam spray nozzle 17 locked because the rotary push button 29 is not indented. On the other hand, because the rotary push button 29 is not rotated from its initial position, a vapor-conducting connection between the wet steam supply line 11 and the first wet steam line 16 in the dual-function valve assembly 27 created so that the whole wet steam flow from the wet steam supply 11 in the steam Nachheizzone 3 flows, see also 1 , and from there via the dry steam line 23 , the dual-function valve assembly 27 evenly distributed through the dry steam line 25 to the front soleplate zone and the dry steam line 24 to the rear soleplate zone, whereby a uniform dry steam exit through the steam outlet holes 6 and 8th takes place to the ironing material. In other words, the front and rear soleplate zones are supplied proportionately with dry steam according to their number of steam outlet holes.

In the second position of the dual function valve assembly 27 to which the rotary pushbutton is turned but not pressed, see 5 , the whole is in the wet steam line 11 inflowing wet steam again through the steam Nachheizzone 3 over the dry steam line 23 returned to the dual-function valve assembly, which is set here so that the rear soleplate zone only reduced over the dry steam line 24 is supplied with dry steam and the majority of the dry steam flow through the dry steam line 25 the front soleplate zone is supplied.

The settings of the dual-function valve assembly 27 according to the 6 and 7 differ from those of 4 and 5 in that according to the 6 and 7 the rotary push button 29 each is pressed. As a result, in each of the two cases, the total wet steam flow coming from the wet steam supply line 11 into the double-function valve assembly 27 inflows, predominantly, ie 80-90%, from the wet steam spray nozzle 17 sprayed, what about the wet steam spray 26 is indicated. The remaining 10 - 20% of the wet steam from the wet steam supply 11 be via the steam post-heating zone 3 into the double-function valve assembly 27 returned and from this only over the dry steam line 25 the steam distribution chamber 7 fed to the front soleplate zone.

The same distribution of in the wet steam supply 11 incoming wet steam also occurs at the fourth position of the dual function valve assembly 27 according to 7 in which only 10 - 20% of the wet steam is reheated to dry steam and the double function valve assembly 27 into the steam distribution chamber 7 the front soleplate zone through the dry steam line 25 turned be fed, although in this position of the double-function valve assembly of the rotary knob is rotated from its initial position. - The third and the fourth function of the iron are thus identical despite different rotational settings of the rotary knob when it is pressed. So there are three different optional effective functions that are adjustable.

The construction of the double-function valve assembly with the functions mentioned is below in view of the 8th to 12 explains:

According to the 8th . 8a . 9 and 9a is in a stationary cylindrical housing 31 a cylindrical rotary valve 39 rotatably mounted, and that is the rotary valve by about 45 ° between a first rotary valve rotational position, the starting position, and a second rotary valve rotational position by means of a rotary pushbutton 29 rotatable. In the rotary valve 39 is a cylindrical plunger slider 49 vertically against a compression spring 62 slidably arranged. The rotary valve 39 and the dive slider 49 are by means of a takeaway nose 44 inside the rotary valve and a driving groove 58 outside of the dive slider connected. Therefore, the rotary valve takes 39 the rotary valve rotary position, which with the rotary pushbutton 29 on the dive slider 49 is set, regardless of the immersion height of the plunger slider 49 in the rotary valve 39 ,

The dual-function valve assembly generally serves to supply wet steam, which is supplied from a steam generator, not shown, for example, via a steam supply line 11 as in 4 - 7 , to a predetermined extent to a wet steam spray nozzle 17 or not, as well as to a steam distribution chamber 5 a rear sole sole zone 4b and a steam distribution chamber 7 a front soleplate zone 4a ,

For this purpose has the housing 31 a wet steam inlet 32 , a first wet steam outlet 33 , a second wet steam outlet 34 , a dry steam inlet 35 , a first dry steam outlet 37 , a second dry steam outlet 38 and inside the bottom of the housing a dry steam bypass 36 , see also 10a and 11a ,

To communicate with these inlets and outlets, has the rotary valve 39 a rotary vane wet steam inlet 40 , a rotary vane wet steam outlet 41 , a rotary vane steam entrance 43 in a bottom of the rotary valve, a first rotary vane dry steam outlet 45 , a second rotary vane dry exhaust outlet 46 , a first reduced rotary vane dry steam outlet 47 and a second reduced rotary vane-dry outlet 48 , The first reduced rotary vane dry steam outlet 47 reduces the dry steam flow compared to the first rotary dry exhaust outlet 45 to 20%. The second reduced rotary impeller steam outlet 48 reduces the dry steam flow based on the second rotary vane dry steam outlet to about 80%.

With the rotary slide inlets and outlets the dive slider works 49 together, which has a dive slider wet steam inlet 50 , a Tauchschiebernassdampfüberströmkanal 52 , a Tauchschiebernassdampfauslass 51 , a dive slider dry steam inlet 54 and a dip slider dry steam outlet 56 having. The plunger slide wet steam inlet communicates with the plunger slide wet steam outlet 51 via a Tauchschiebernassdampfkammer 57 in connection. The dive slider dry steam inlet 54 is via a dive slider dry steam chamber 64 with the dive slider dry steam outlet 56 connected and goes outside to the diving chamber in a Tauchschiebertrockendampfüberströmkanal 55 above.

From the outer periphery of the plunger slider is still a wet steam overflow channel 52 shaped and forms together with a recess inside the rotary valve a wet steam bypass 53 in the lowered position of the plunger slide 49 , please refer 8a and 9a , The wet steam bypass 53 is in coordination with the other, not blocked steam line sections dimensioned so that it only about 20% of the wet steam inlet of the housing flowing wet steam to the first rotary vane wet steam outlet 41 conducts, while in this state of the plunger the remaining 80% wet steam through the Tauchschiebernassdampfkammer 57 to the Tauchschiebernassdampfauslass 51 stream.

In 8th is the dual-function valve assembly 27 in its initial position in the unactuated state of the rotary pushbutton 29 corresponding 4 shown. At this setting, the wet steam passes over the wet steam line 11 and the wet steam entrance 32 of the housing 31 , the rotary vane assembly steam entrance covering it 40 and flows over the Tauchschiebernassdampfüberströmkanal 52 , the first rotary vane wet exhaust 41 and the wet steam outlet 33 of the housing 31 over the first wet steam line 16 in the steam Nachheizzone 3 , see also 4 , In the steam Nachheizzone the flowing wet steam is reheated, so that it as dry steam in the dry steam line 23 enters and the dry steam inlet 35 of the housing 31 reached. From this, the dry steam flows over the rotary vane dry steam inlet 43 , the immersion slide inlet 54 , the dive slider dry steam outlet 56 , the space between the bottom of the plunger and the bottom of the rotary valve in the first rotary impeller steam outlet 45 and the second rotary vane dry exhaust outlet 46 and the first dry steam outlet 37 or the second dry steam outlet 38 of the housing via the dry steam line 24 in the rear steam distribution chamber 5 or via the dry steam line 25 on the housing in the front Dampfverteilkammer 7 , As a result, both ironing sole zones 4a . 4b according to the number of their steam outlet holes 8th respectively. 6 evenly supplied with dry steam. This represents the first function of the iron.

When unpressed by 45 ° in the second rotary valve rotary position turned rotary pushbutton 29 according to 9 for the in 5 schematically illustrated second function, the same inlet and outlet operations of the wet steam or dry steam as above 8th described, with the following exception:

In the second rotary valve rotational position, the second rotary gate dry steam outlet is 46 at the bottom of the rotary valve through the bottom surface of the housing 31 closed and the first equal sized rotary slide dry steam outlet 45 is over the second dry steam outlet 38 of the housing 31 driven, while the first reduced rotary vane dry steam outlet 47 above the first dry steam outlet 37 of the housing 31 sits, see also 11b , compared to 10b in which the rotary valve bottom is shown in its initial position. The position of the bottom of the rotary valve according to 11b respectively. 10b is respectively corresponding to the position of the bottom of the housing 11a respectively. 10a to see.

From the 10a and 11a are still the cutting curves AB and EF recognizable in which the 8th respectively. 9 are shown in the region of the bottom of the rotary valve. On the rotational position of the dive slider 49 it comes in the 8th and 9 not because in each rotational position, the gap between the bottom of the plunger and the bottom of the rotary valve through the central Tauchschiebertrockendampfauslass 56 is subjected to dry steam.

As a result of the too 9 described rotary valve rotational position reach only 10 - 20% of the dry steam from this space in the soleplate zone 4b while 80-90% of the dry steam for the soleplate zone 4a be available. The inlet and outlet processes between the outer surface of the rotary valve 39 and the inner surface of the housing 31 remain preserved because the inlet and outlet openings through the jacket of the rotary valve 39 as in the circumferential direction 45 ° overlapping slots are formed, see 12 ,

For the third function of the iron accordingly 6 with untwisted pressed rotary pushbutton 29 take the rotary valve 39 and the dive slider 49 in the 8a shown first rotary valve rotational position and lowered plunger slide position, wherein the wet steam from the wet steam line 11 into the wet steam inlet 32 of the housing 31 and the rotary vane wet steam inlet hiding therewith 40 flows. 80-90% of this wet steam flow passes through the immersion slide wet steam inlet open in this position 50 , the dive slid wet steam chamber 57 to the Tauchschiebernassdampfauslass 51 , the second rotary vane wet steam outlet 42 and the second wet steam outlet of the housing from which it passes via the second wet steam line 18 to the wet steam spray nozzle 17 from which it emerges as a wet steam spray. On the other hand, only a partial amount of about 10 to 20% of the rotary vane inlet steam inlet flows 40 entering wet steam flow over in this position of the plunger slide 49 formed wet steam bypass 53 , the immersion slide wet steam overflow channel 52 , the first rotary vane wet exhaust 41 and the first wet steam outlet 33 of the housing via the first wet steam line 16 in the steam Nachheizzone 3 , please refer 6 , In this, the wet steam is reheated and flows as dry steam over the dry steam line 23 , the dry steam inlet 35 of the valve housing 31 , the rotary vane steam inlet 43 and the dive slider dry steam inlet 54 into the dive slipper dry steam chamber 64 and from there via the dive slider dry steam outlet 56 , the second rotary sliding dry steam outlet 46 and the second dry steam outlet 38 of the housing and the dry steam line 25 into the front steam distribution chamber 7 ,

As a result of the dive slider pushed 49 are by the attached at its outer bottom elastic sealing body 59 the first rotary vane dry exhaust outlet 45 and the first reduced rotary screed steam outlet 47 closed, see 10c , As a result, 80-90% of the wet steam flow entering the wet steam inlet 32 is introduced via the wet steam spray nozzle 17 sprayed and 10 - 20% of the steam volume are in the form of dry steam only the front soleplate zone 4a fed. This is the third function of the iron.

With the rotary knob pressed turned 29 according to 9a With respect to the inlet and outlet operations of the steam in or out of the housing takes place the same function as the third function described above, the only reason here as fourth function can be called, because inside the housing of the rotary valve 39 is rotated in the second rotary valve position by 45 °. However, since the rotary valve 39 opposite the plunger slider 49 is unrotatable, are also here by the depressed rotary push button 29 the first rotary vane dry exhaust outlet 45 , the second rotary vane dry steam outlet 46 and the first reduced dry steam outlet 47 through the elastic seal body 59 closed at the bottom of the rotary valve, and it passes though the first rotary impeller steam outlet 45 over the second dry steam outlet 38 of the housing is rotated, and the first reduced rotary vane dry steam outlet 47 over the first dry steam outlet 37 of the housing is rotated, no dry steam in this way in the first dry steam outlet 37 and the second dry steam outlet 38 of the housing 31 , Only by the central in the rotary valve 39 arranged second reduced rotary vane dry steam outlet 48 and the dry steam bypass 36 The dry steam from the Tauchschiebertrockendampfkammer 64 in the second dry steam outlet 38 of the housing and of this via the dry steam line 25 into the steam distribution chamber 7 for the front soleplate zone, see 7 , This steam distribution chamber 7 So only 10 - 20% of the wet steam inlet 32 fed wet steam, while the main part of the wet steam flow, namely 80- 90% in turn through the Tauchschiebernassdampfkammer 57 , the immersion slide wet steam outlet 51 and the second wet steam outlet 34 the wet steam spray nozzle 17 is fed, which is the wet steam spray 26 on the ironing material eject, see 7 ,

In the function of the wet steam spray, it is therefore irrelevant whether the rotary knob 29 is rotated in its first rotary valve rotational position or in its second rotary valve rotational position; In any case, it will have a low wet steam content of 10-20% of the total wet steam flow entering the dual function valve unit 27 flows in, as a peak steam through the steam outlet holes 8th release the front soleplate zone to prevent scorching or shine even when the iron is not lifted off the ironing material.
