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 invention relates to a steam ironing system with a stationary steam generator and an iron connected thereto according to the preamble 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 ).

In conventional steam irons arranged on the front of the iron spray nozzles for structural reasons are relatively high on the iron and thus located high above the ironing. This leads to a relatively wide spray, which is usually wider than the problem zone to be moistened the ironing material.

Also, the high arrangement of the spray nozzle often unwanted sprayed far in front of the iron. Practiced practice with the operators is therefore to lift off the iron for the spray process, to hold the iron at an angle over the problem zone and to spray it directly.

In the case of irons with an external steam generator, on the other hand, because there is no water tank or water supply system to the steam chamber, it is possible to place the spray nozzle relatively low on the front side of the iron. This allows the problem zone to be moistened directly and specifically against the iron.

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 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 moistening point of 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 about 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, depending on the contact position, it supplies the steam supplied to it - wet steam - either only via the steam chamber to the steam outlet holes in the front part of the sole, or of the area spraying the area before the 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 through an adjustment valve with rotating knob set, which is arranged 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 reversible Dampfreduzier- / locking device over which the Teilmengedampfaustrittslöcher in a first switching position in maximum steam-conducting Connection with the steam generator and in a second switching position at most reduced in steam-conducting connection, the remaining steam outlet holes are in both Umschaltstellungen with the steam generator in vapor-conducting connection ( EP 1 178 147 A2 ). Specifically, the switchable steam reducing / blocking device has a switchable from the outside directly on the iron switching element and a steam inlet and at least one steam outlet. - 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 spots or the steam does not penetrate sufficiently into a thick, absorbent natural fiber material such as cotton, so that it would have to be repeatedly moistened and ironed. 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 the distribution of the first and second liquid partial streams of the second evaporator chamber are not easily adjusted properly depending on the ironing material. In addition, the steam iron is not intended for connection to an external stationary steam generator.

The present invention has for its object, while avoiding the disadvantages of prior art steam ironing this form so that with straightforward adjustability, namely easy switching between wet steam spray with a wet steam spray or steam through steam outlet holes in the sole even when not lifted off the iron irons scorching or gloss ironing prevented becomes.

This object is achieved for a steam ironing system of the type mentioned in the characterizing part of claim 1 by a vapor bypass, which is arranged between a steam inlet of a switching valve used for the aforementioned switching and a first steam outlet of this switching valve so that the steam outlet openings in the sole of the Iron be acted upon at each switching position of the change-over valve with at least a small subset of the steam introduced into the steam inlet steam.

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

The solution according to the invention is characterized by a low design complexity. In particular, the steam bypass between the steam inlet and the first steam outlet of the switching valve can be realized by not completely shutting off the steam inlet from the first steam outlet when it is opened to the second steam outlet. So it is so far no absolutely tight precision change-over valve required. It is desired, however, that the steam outlet from the wet steam spray nozzle is completely blocked when the switching valve occupies a switching position for passing the steam from the stationary steam generator to the first steam outlet, which preferably leads via the steam Nachheizzone to the steam outlet holes in the sole.

Preferably, the iron, which belongs to the steam ironing system with a stationary steam generator of the type mentioned, 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 in the steam inlet introduced steam are applied. This is achieved by dry ironing of the previously sprayed with the wet steam ironing a particularly good ironing result despite the small subset dry steam leaving the sole of the iron through the steam outlet holes.

In general, it is advantageous if the steam supplied to the iron in the steam ironing system from the stationary steam generator, which is cooled in the steam line and partially condensed and therefore hereinafter referred to as wet steam, is heated in the steam Nachheizzone of the iron to dry as a steam to escape the steam outlet openings of the sole and even then to achieve a good ironing result in the switching position of the changeover valve, in which the ironing material is acted upon exclusively by the steam outlet holes in the sole with steam.

The steam Nachheizzone is suitably realized according to claim 6 by a heated steam chamber. For this purpose, in particular according to claim 7, at least one electric heating element can be used, which is also thermally conductively connected to the sole of the iron. For this purpose, it is advantageously arranged in an iron foot of good heat conducting material from which the steam chamber is formed and which forms or carries the sole below. As a result, the effort to generate the dry steam is kept low. The heated steam chamber may be downstream in terms of flow one or more steam chambers, which adjoin the sole of the iron with the steam outlet holes and serve for the distribution of steam.

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 more powerful, more complex steam generators, an iron in the steam ironing system is used according to claim 4, the sole in a rear soleplate zone a subset of the total existing 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 at best in only reduced steam-conducting connection with the steam generator. The remaining steam outlet holes, which are arranged in the front soleplate zone, are acted upon in both switching positions of the steam reduction / 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 emerging from the steam outlet of the changeover valve steam is divided evenly to 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 Dampfreduzier Because of the reduced steam supply to the subset of steam exit holes in the rear soleplate zone, the majority of the steam is supplied to the remaining steam exit holes located in the front soleplate zone.

According to claim 5 preferably only up to about 20% of the steam from the steam outlet of the changeover valve of the subset steam outlet holes in the rear soleplate zone supplied in the second switching position and the vast majority of the steam, ie about 80% the other steam outlet holes in the front Soleplate zone. - The division thus always refers to the amount of steam leaving the steam outlet of the upstream switching valve, ie in a first switching position of the switching valve, the total of the steam inlet supplied steam and in a second position of the changeover valve only the small subset of introduced into the steam inlet of the changeover valve Steam while the bulk of this steam is sprayed from the wet steam spray nozzle.

By having the switchable steam reducing / blocking device having a first switching element operable directly from the outside of the iron and a steam inlet communicating with the first steam outlet of the switching valve, the steam reducing / blocking device can be made compact so as to take up little space in the iron , It is also so easy to press while ironing.

The switchable vapor reduction / blocking device may be completed into a compact and easily assembled component according to claim 9 by having a first vapor outlet connected to the subset of vapor exit holes and having a second vapor outlet connected to the remaining vapor exit holes and the first vapor outlet and the second vapor outlet is led out of a chamber of the vapor reduction / blocking device which is open in the first switching position to the first vapor outlet and the second vapor outlet and which is open in the second switching position to the second vapor outlet and only reduced to the first vapor outlet is open. The reduced opening to the first steam outlet represents the steam bypass.

Thus, the steam bypass assembly is conveniently formed in the switching valve.

Particularly compact and user-friendly but is the overall arrangement of the switching valve and the switchable Dampfreduzier- / locking device according to claim 11, characterized in that the switching valve and the switchable Dampfreduzier- / locking device are integrated into a Doppelfunktionsventilbaueinheit with a housing and that the Doppelfunktventilbaueinheit only one of the outside directly on Iron-actuated rotary push button has as a combined actuator. The advantage here is that not two components, namely the switching valve and the switchable Dampfreduzier- / locking device must be mounted separately with one actuator and that at least one external line between the switching valve and the switchable Dampfreduzier- / Sperrvor-direction can be omitted. In operation, the operation is simplified because during ironing only one combined actuator is to adjust if necessary and the ironing person does not need to distinguish between two actuators to operate the selected element.

More specifically, the integration of the switching valve and the switchable steam reducing / blocking device to the double-function valve assembly with the housing having the features specified in claim 1 2 is realized. Despite the dual function, this double function valve assembly is easy to produce with a few elements. Three different functions of the iron can be adjusted by the single combined actuator obvious, namely a first function in untwisted and depressed Rotary pushbutton, if only dry steam is to flow evenly out of the sole of the iron, a second function with turned depressed rotary pushbutton, in which increased peak steam flows long time out of a front soleplate zone, while only a little dry steam needs to flow out of the rear soleplate zone, and a third function in pressed rotary pushbutton, regardless of whether this is rotated or not, to spray wet steam from a wet steam spray nozzle arranged on the front of the iron on the ironing material and still allow some dry steam to emerge as a peak steam from the front soleplate zone.

According to claim 12, the double-function valve assembly, with which these functions are adjustable, substantially only three components, except the housing a rotary valve and a plunger slide, which are set together in the housing in one of two rotational positions to activate the first or the second function can. 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 constructive detail in this respect, the plunger slide according to claim 13 is designed substantially as a cylinder which is vertically displaceable in the rotary valve against the force of a spring, and the rotary valve, which is formed substantially as a hollow cylinder, and the plunger slide by means of a driving lug of the rotary valve and one of these receiving driving the dipping slide against each other non-rotatably but slidably connected.

The wet steam bypass over which a small portion of the wet steam flowing into the dual function valve assembly is supplied to the front soleplate zone after heating in a steam postheating zone when the steam iron operates for wet steam spray operation may be suitably wet-wet bypassed between the wet steam inlet and the first wet steam outlet in FIG the double function valve assembly be molded.

Space-saving and structurally uncomplicated, the wet steam bypass according to claim 15 is formed with an indented plunger slide 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 of the plunger slide and an inner peripheral contour of the rotary valve.

The rotary valve serves on the one hand in conjunction with the plunger slide for switching the wet steam to the wet steam spray and on the other to distribute the wet steam formed by reheating dry steam to flow out of the front and rear soleplate zone in predetermined proportions and he ensures in conjunction with the plunger slide the outlet a small subset of dry steam from the forward soleplate zone as peak vapor when the wet steam spray nozzle is activated.

For controlling the wet steam, according to claim 16, there is provided in the rotary valve a rotary slide wet steam inlet connected to the wet steam inlet of the housing in each rotary position of the rotary valve in such a way that a first rotary rotary wet steam outlet is formed in the rotary valve Rotary position of the rotary valve is connected to the first wet steam outlet of the housing and is in Strömsmässiger connection with pushed-in plunger slide over a Tauchschiebernassdampfkammer and a formed in the rotary valve second Drehschiebernassdampfauslass with the second wet steam outlet of the housing.

Furthermore, to control the dry steam to the rear soleplate zone, which is connected to the first dry steam outlet, and 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 are provided. Thus, in particular, two possibilities or functions of the distribution of the dry steam are controlled when the wet steam spray nozzle is switched off.

In order to effect the desired outlet of peak steam to a reduced extent with activated wet steam spray nozzle independently, the rotary valve has the stated in the characterizing part of claim 18 features. This ensures that when the wet steam spray nozzle is active, this 80-90% of the wet steam entering the double-function valve assembly is released as wet steam spray, while the remaining 10-20% emerge after reheating as dry steam from the steam outlet holes of the front iron sole zone.

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

The above-specified relation of the wet steam spray exit from the wet steam spray nozzle to the dry steam exit from the forward sole is achieved by reducing the steam flow to the second dry steam outlet first through the wet steam bypass and then through the dry steam bypass in the dual function valve assembly according to claim 20.

In order to achieve the relations of the wet steam spray ejection to the dry steam outlet from the front soleplate zone independently of the rotary valve rotational adjustment, the uncomplicated structural features of claim 21 are provided.

The immersion slide is subdivided according to a structurally simple sensible solution according to claim 22 substantially in a Tauchschieber-dry steam chamber and in a Tauchschiebernassdampfkammer, each equipped with inlets and outlets for controlling the dry steam or 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 Figures 1 to 3 and the second embodiment according to Figures 6 to 12 are provided with the same reference numerals.

In Figure 1, an iron housing 1 comprises a Nachheizkörper 2, which is designed as an iron foot and a steam Nachheizzone 3 includes. The iron foot stands with a sole 4 in heat-conducting connection.

From the Nachheizkörper 2 a Dampfverteilkammer 5 is formed for a rear soleplate zone 4b, which includes a subset of steam outlet holes 6, and a Dampfverteilkammer 7 for a front soleplate zone 4a with other steam outlet holes 8 for so-called peak steam. Inserted into the afterheater is 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, in addition to the electrical supply line 10, a wet steam supply line 11 is introduced, which is in communication with an external stationary steam generator, not shown.

The wet steam supply line 11 leads to a switching valve 12 with an actuating mechanism 13 and a push button 14, which is slidably mounted in a pushbutton guide 1 5.

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

In the same area, a switchable Dampfreduzier- / locking device 19 with an actuating mechanism 20 and a push button 21 is actuated, which is slidably mounted in a push button guide 22.

The switchable Dampfreduzier- / blocking device has on the input side a dry steam line 23, which is led out of the steam Nachheizzone 3, and on 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 the operation of the steam ironing system with the described iron and the stationary external steam generator steam flows through the steam supply line 11 into 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, so that dry steam flows out of the soleplate 4, 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 wet steam flowing into the changeover valve 12 in the actuated position of the changeover valve shown in FIG. 3 is supplied as such to the wet steam spray nozzle 17, which sprays a moisture mist onto the ironing material. 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 change-over valve 12, a small subset of the wet steam supplied to the switching valve is replaced by the first wet steam line 16 of the steam Nachheizzone 3 supplied. This is done by a steam bypass 1 2a in the switching valve or in this initial position only imperfect completing the first wet steam supply 16 relative to the wet steam supply 11 to the extent that 80-90% of the flowing into the switching valve 1 2 wet steam is passed to the wet steam spray nozzle 17 and only 10-20% of the wet steam through the first wet steam line 16 to the steam post-heating zone 3 and via the steam reducing / blocking device 19 to the steam distribution chamber 7 for the front soleplate zone and to the steam ironing chamber 5 for the rear soleplate zone, of which the dry steam is acted upon by the steam outlet holes 8 and 6, the ironed. 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% distributed to the front and the rear soleplate zones 4a and 4b, as below too Fig. 2 will be explained. So that scorching or shine is reliably prevented even when not lifted off the ironing iron.

In contrast, in the initial position of the switching valve 12 shown in FIG. 1, the entire wet steam introduced into the latter is supplied via the first wet steam line to the steam afterheating zone 3, from which dry steam formed by reheating passes into the dry steam line 23 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 and the steam distribution chamber 7 for the front soleplate zone 4a opened that the ironed according to the number of steam outlet holes 6 for the rear soleplate zone and 8 for the front soleplate zone evenly with dry steam is applied.

For special ironing tasks, the steam reducing / blocking device 1 9 is operated according to Figure 2, after which only a reduced amount of dry steam from the steam reducing / blocking device via the dry steam line 24 of the steam distribution chamber 5 is supplied to the rear soleplate zone, while the main part of the dry steam through the dry steam line 25 flows into the steam distribution chamber 7 for the front soleplate zone 4a. The ironing material is therefore essentially subjected to increased peak steam. Specifically, the dry steam flow from the dry steam line 23 is divided so that 80% of the dry steam in the front soleplate zone 4a and only about 20% of the dry steam are fed into the rear soleplate zone.

Thus, during normal ironing operation, the steam dry-lock device can be divided with the steam-inhibiting barrier device so as to be split into either the front and rear soleplate zones 4a, 4b which are separated from one another according to the number of steam outlet holes 8, 6, respectively, and then the ironed article is uniformly supplied 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 especially peak steam is delivered.

If, in contrast, only the changeover valve is actuated, but not the steam reducing / blocking device, then 80-90% of the wet steam flow which flows into the changeover valve 12 is sprayed out of the wet steam spray nozzle 17 and 10-20% of the mentioned Wet steam flow are uniformly conducted via the steam Nachheizzone 3 in the front and in the rear ironing zone 4b and 4a. - This combination of the position of the switching valve 12 and the Dampfreduzier- / locking device 1 9 is not shown in the drawing.

In a preferred embodiment of the invention according to FIGS. 4 to 12, the changeover valve and the switchable steam reducing / blocking device are combined to form a double function valve assembly 27 which can be actuated via an actuating mechanism 28 with a rotary pushbutton 29. The rotary push button 29 is rotatably mounted in a rotary pushbutton guide 30 and pressed down, see Figure 4.

The assignment of four settings of the double-function valve assemblies 27 to four functions that can be exercised with the iron is first explained with reference to FIGS. 4 to 7. Details of the double-function valve assembly with which the functions are realized will be explained below with reference to FIGS. 8 to 12.

In Figure 4, the steam iron with the dual function valve assembly is shown in a first position in which the rotary push button 29 is unconfirmed, that is neither rotated from its initial position shown nor pressed. In this first position of the double-function valve assembly 27, a wet steam supply from the wet steam supply line 11 from the steam generator to the second wet steam line 18 and the wet steam spray nozzle 17 is blocked because the rotary push button 29 is not depressed. By contrast, 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 double function valve assembly 27 created so that the whole wet steam flow from the wet steam supply 11 flows into the steam Nachheizzone 3, see also Figure 1, and from there via the dry steam line 23, the double 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 outlet through the steam outlet holes 6 and 8 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 double-function valve assembly 27 to which the rotary pushbutton is turned but not depressed, see Figure 5, the entire wet steam flow flowing into the wet steam line 11 is in turn fed back through the steam postheating zone 3 via the dry steam line 23 to the double function valve assembly, here is set, 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 of the front soleplate zone is supplied.

The settings of the double-function valve assembly 27 according to FIGS. 6 and 7 differ from those of FIGS. 4 and 5 in that, according to FIGS. 6 and 7, the rotary push-button 29 is in each case pressed in. As a result, in all of the two cases, the entire wet steam flow flowing from the wet steam feed line 11 into the double-function valve assembly 27 predominantly, ie 80 - 90%, sprayed from the wet steam spray nozzle 17, which is indicated by the wet steam spray 26. The remaining 10 - 20% of the wet steam from the wet steam supply line 11 are returned via the steam Nachheizzone 3 in the double function valve assembly 27 and fed from this only via the dry steam line 25 of the steam distribution chamber 7 of the front soleplate zone.

The same distribution of the wet steam flowing into the wet steam feed line 11 also occurs in the fourth position of the double-function valve assembly 27 according to FIG. 7, in which only 10-20% of the wet steam is reheated to dry steam and via the double-function valve assembly 27 into the steam distribution chamber 7 of the front ironing sole zone are fed through the dry steam line 25, although in this position, 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.

• Gemäss den Figuren 8, 8a, 9 und 9a ist in einem ortsfesten zylindrischen Gehäuse 31 ein zylindrischer Drehschieber 39 drehbar gelagert, und zwar ist der Drehschieber um ca. 45° zwischen einer ersten Drehschieberdrehstellung, der Ausgangsstellung, und einer zweiten Drehschieberdrehstellung mittels eines Drehdruckknopfes 29 drehbar. In dem Drehschieber 39 ist ein zylindrischer Tauchschieber 49 vertikal gegen eine Druckfeder 62 verschiebbar angeordnet. Der Drehschieber 39 und der Tauchschieber 49 sind mittels einer Mitnahmenase 44 innen an dem Drehschieber und einer Mitnahmenut 58 aussen an dem Tauchschieber miteinander verbunden. Daher nimmt der Drehschieber 39 die Drehschieberdrehstellung ein, die mit dem Drehdruckknopf 29 an dem Tauchschieber 49 eingestellt wird, und zwar unabhängig von der Eintauchhöhe des Tauchschiebers 49 in dem Drehschieber 39.

The structure of the double-function valve assembly with the functions mentioned will be explained below with reference to FIGS. 8 to 12:

• According to Figures 8, 8a, 9 and 9a, a cylindrical rotary valve 39 is rotatably mounted in a stationary cylindrical housing 31, 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 push button 29th rotatable. In the rotary valve 39, a cylindrical plunger slide 49 is vertical slidably disposed against a compression spring 62. The rotary valve 39 and the plunger slide 49 are connected to each other by means of a driving lug 44 on the inside of the rotary valve and a driving groove 58 on the plunger slide. Therefore, the rotary valve 39 takes the rotary valve rotational position, which is set with the rotary push button 29 on the plunger 49, regardless of the immersion height of the plunger 49 in the rotary valve 39th

The dual-function valve assembly generally serves to supply wet steam, which is supplied from a steam generator not shown, to a wet steam spray nozzle 17 by a steam supply 11 as in FIGS. 4-7, and to a steam distribution chamber 5 of a rear iron sole zone 4b and a steam distribution chamber 7 of a front soleplate zone 4a.

For this purpose, the housing 31 has 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 a dry steam bypass 36 inside the bottom of the housing, see also FIGS. 10a and 11a.

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

The rotary valve inlets and outlets cooperate with the plunger slide 49, which has a plunge slide wet steam inlet 50, a plunge wet wet steam transfer passage 52, a plunger wet steam outlet 51, a plunger dry steam inlet 54, and a plunger dry steam outlet 56. The immersion slide wet steam inlet communicates with the immersion slide wet steam outlet 51 via a plunger slide wet steam chamber 57. The dip slider dry steam inlet 54 is connected to the dip slider dry steam outlet 56 via a dip slider dry steam chamber 64 and transitions outside the dip chamber into a dip slider dry steam transfer channel 55.

From the outer periphery of the plunger slide a wet steam overflow channel 52 is further formed and forms together with a recess inside the rotary valve a wet steam bypass 53 in the lowered position of the plunger slide 49, see Figure 8a and 9a. The wet steam bypass 53, in coordination with the remaining, non-blocked steam line sections, is dimensioned to direct only about 20% of the wet steam entering the wet steam inlet of the housing to the first rotary wet steam outlet 41, while in this state of the plunger the remaining 80% wet steam passes through the wet steam bypass Immersion wet steam chamber 57 to the Tauchschiebernassdampfauslass 51 flow.

In Figure 8, the dual function valve assembly 27 is shown in its initial position in the unactuated state of the rotary push button 29 according to Figure 4. In this setting, the wet steam enters via the wet steam line 11 and the wet steam inlet 32 of the housing 31, the rotary vane pass steam inlet 40 which covers it, and flows in via the wet scrubber vaporizer passage 52, the first rotary vane vapor outlet 41 and the wet steam outlet 33 of the housing 31 via the first wet steam line 16 The steam Nachheizzone 3, see also Figure 4. In the steam Nachheizzone the flowing wet steam is reheated so that it enters as dry steam in the dry steam line 23 and reaches the dry steam inlet 35 of the housing 31. From this, the dry steam flows via the rotary lubricated steam inlet 43, the plunger slide inlet 54, the plunger dry steam outlet 56, the space between the bottom of the plunger and the bottom of the rotary valve into the first rotary dry exhaust outlet 45 and the second rotary dry exhaust outlet 46 and the first dry steam outlet 37 and the second dry steam outlet, respectively Thus, the two ironing brine zones 4a, 4b are supplied uniformly with dry steam in accordance with the number of their steam outlet holes 8 and 6, respectively. This represents the first function of the iron.

• In der zweiten Drehschieberdrehstellung ist der zweite Drehschiebertrockendampfauslass 46 am Boden des Drehschiebers durch die Bodenfläche des Gehäuses 31 verschlossen und der erste gleich grosse Drehschiebertrockendampfauslass 45 ist über den zweiten Trockendampfauslass 38 des Gehäuses 31 gefahren, während der erste reduzierte Drehschiebertrockendampfauslass 47 über dem ersten Trockendampfauslass 37 des Gehäuses 31 sitzt, siehe auch Figur 11b, im Vergleich zu Figur 10b, in der der Drehschieberboden in seiner Ausgangsstellung dargestellt ist. Die Position des Bodens des Drehschiebers gemäss Figur 11 b bzw. 10b ist jeweils in Verbindung mit der Position des Bodens des Gehäuses entsprechend Figur 11a bzw. Figur 10a zu sehen.

When unpressed rotated by 45 ° in the second rotary valve rotational position knob 29 shown in Figure 9 for the second function shown schematically in Figure 5, the same input and output operations wet steam or dry steam as described above for FIG. 8, with the following exception:

• In the second rotary valve rotational position, the second rotary vane dry steam outlet 46 at the bottom of the rotary vane is closed by the bottom surface of the housing 31 and the first equal rotary vane dry steam outlet 45 has passed over the second dry steam outlet 38 of the housing 31 while the first reduced rotary vane dry steam outlet 47 overlies the first dry steam outlet 37 of the housing Housing 31 is seated, see also Figure 11b, in comparison to Figure 10b, in which the rotary valve bottom is shown in its initial position. The position of the bottom of the rotary valve according to Figure 11 b and 10b can be seen in each case in conjunction with the position of the bottom of the housing according to Figure 11a and Figure 10a.

FIGS. 10a and 11a furthermore show the sections A-B and E-F, respectively, in which FIGS. 8 and 9 are shown in the region of the bottom of the rotary valve. On the rotational position of the plunger slide 49 is not important in Figures 8 and 9, since in each rotational position of the gap between the bottom of the plunger and the bottom of the rotary valve is acted upon by the central Tauchschiebertrockendampfauslass 56 with dry steam.

As a result of the rotary valve rotational position described for FIG. 9, only 10-20% of the dry steam passes from this interspace into the soleplate zone 4b, whereas 80-90% of the dry steam is available for the soleplate zone 4a. The inlet and outlet operations between the outer surface of the rotary valve 39th and the inner circumferential surface of the housing 31 are retained, because the inlet and outlet openings are formed by the jacket of the rotary valve 39 as in the circumferential direction 45 ° overlapping slots, see Figure 12th

For the third function of the iron according to Figure 6 with untwisted pressed rotary pushbutton 29 take the rotary valve 39 and the plunger 49 shown in Figure 8a first rotary valve position and lowered plunger position, the wet steam from the wet steam line 11 in the wet steam inlet 32 of the housing 31 and the flows with him covering rotary slide wet inlet 40. 80-90% of this wet steam flow pass through the plunger wet steam inlet 50 open in this position, the plunger wet steam plenum 57 to the plunger wet steam outlet 51, the second rotary steam exhaust 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 he exits as a wet steam spray. On the other hand, only a partial amount of approximately 10-20% of the wet steam flow entering the rotary slide steam inlet 40 flows via the wet steam bypass 53 formed in this position of the plunger slide 49, the plunger wet steam transfer passage 52, the first rotary slide wet outlet 41 and the first wet steam outlet 33 of the housing via the first wet steam line 16 in the steam Nachheizzone 3, see Figure 6. In this, the wet steam is reheated and flows as dry steam through the dry steam line 23, the dry steam inlet 35 of the valve housing 31, the rotary vane dry steam inlet 43 and the Tauchschiebertrockendampfeinlass 54 in the Tauchschiebertrockendampfkammer 64 and from there via the Diving slider dry steam outlet 56, the second rotary dryer dry outlet 46 and the second dry steam outlet 38 of the housing and the dry steam line 25 in the front Dampfverteilkammer. 7

As a result of the depressed plunger slide 49, the first rotary impeller steam outlet 45 and the first reduced rotary impeller dry exhaust outlet 47 are closed by the elastic sealing body 59 attached to its outer bottom, see FIG. 10c. Accordingly, 80-90% of the wet steam flow introduced into the wet steam inlet 32 is sprayed via the wet steam spray nozzle 17 and 10-20% of the steam volume is supplied in the form of dry steam only to the front ironing sole zone 4a. This is the third function of the iron.

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, which can be referred to here only as a fourth function, because within the housing of the rotary valve 39 is rotated in the second rotary valve rotational position by 45 °. However, since the rotary valve 39 with respect to the plunger 49 is not rotatable, here by the depressed rotary push button 29, the first Rotary dry exhaust outlet 45, the second Rotary dry exhaust outlet 46 and the first reduced dry steam outlet 47 closed by the elastic sealing body 59 down to the bottom of the rotary valve, and although the first rotary dry steam outlet 45 is rotated across the second dry steam outlet 38 of the housing and the first reduced rotary dry flue outlet 47 is rotated across the first dry steam outlet 37 of the housing, no dry steam is encountered In this way, in the first dry steam outlet 37 and the second dry steam outlet 38 of the housing 31. Merely by the centrally arranged in the rotary valve 39 second reduced rotary impeller 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 This steam distribution chamber 7 are supplied so only 10 - 20% of the wet steam introduced into the wet steam inlet 32, while the main portion of the wet steam flow, namely 80 - 90% turn is fed through the Tauchschiebernassdampfkammer 57, the Tauchschiebernassdampfauslass 51 and the second wet steam outlet 34 of the wet steam spray nozzle 17, which discharges the wet steam spray 26 on the ironing material, see Figure 7.

In the function of the wet steam spray ejection, it is therefore irrelevant whether the rotary push button 29 is rotated in its first rotary valve rotational position or in its second rotary valve rotational position; in any case, a low wet steam content of 10-20% of the total wet steam flow flowing into the double-function valve unit 27 is discharged as peak steam through the steam outlet holes 8 of the front soleplate zone to avoid scorching or glossing even when the iron is not lifted off the ironing material.
