The back door can present subareas, which extend beyond the pure side rear of the housing to other areas of it, for example to lateral areas as well as lower areas of the housing, whenever you are, in operation of the device, for the Rear door material used, are not exposed to high temperatures In order to ensure the achievement of airtightness required rear door closure have been provided hermetic elements that are described in depth to then, which are provided in the closure cap or in the water filling tubular hole (or respectively within the water filling opening) or both of these pieces. Stopper closure is preferably formed as an integral part of the back door. Under water tank, in the sense of the invention, it should be understood, not just a container for the reception of water, but a container to accommodate any type of medium evaporable liquid suitable for steam ironing, including appropriate additives provided in this medium. Water tank it can present one or several cameras or also cover one or more of a separate unit of container tanks, which can Present the same or different volume.

The steam ironing device according the invention, according to the construction of the back door explained previously, it has a simple and easy to use closing system effective, economical ergonomic, easy and not complicated, and yet Safe and airtight, for side water filling opening rear. The back door, with its captive closure cap, is also attached to the housing. For opening the opening of filled with water, the rear door is simply uncovered. The door rear then offers, in a state of complete opening, an access unobstructed to the water filling opening, so that the Water tank can be filled comfortably from the back side of the steam ironing device and the filling opening of water can finally be closed again simply by pressurized The closure system on the back side of the water filling opening, according to the invention of the steam ironing device with housing and back door as well As the tight connection to the water tank can be implemented quite simply and compared to few loose pieces of relatively simple assembly. Those components are made, such as It is common in the manufacture of steam ironing devices for pieces with only low thermal load, such as injection parts plastic, so construction injection forms are allowed to be used simple. In addition, the solution according to the invention allows a easier assembly, especially of the water tank, of the system closure of the back side of the water filling opening, as well as of the existing housing parts on this site or areas of Case. At the same time it can also be done, from the part  rear of the housing, mounting the loose components or the water filling device respectively. This does more Simple production and reduce manufacturing costs.

In a preferred embodiment according to the invention of the steam ironing device, on the rear side a funnel-shaped housing entry is formed, with a funnel tubular hole which forms the tubular hole of Water filling with water filling opening. Entry into the funnel-shaped housing extends in this case preferably over a large part of the side surface rear. This type of construction simplifies tank filling with water and reduces the possibility of unwanted spillage of water to fill

It has also been proven favorable, when the rear door has a funnel-shaped or concave area, which extends from an outer area of the edge of the back door up to the closure cap, and whose inner contour in closed state of the back door and the water filling opening, it is essentially largely parallel to the outer contour of the funnel-shaped housing inlet of the back side This makes it possible not only an auspicious occasion for constructive technical training of the closure cap and the Remaining areas of the back door in one piece, but it also facilitates in the rear the formation of a molding of grab with one or more of a grab elements (see below).

It is preferred that the revolving rear door be attachable to the back side of the case or on it, since this in parallel it allows a simpler production, as well as better integration of the back door into the housing and its rear side used as support surface. At first partial areas of the back door can be mounted, which they present their axis of rotation, however, also on other sides of the housing, especially in lateral areas or upper side of the Case. This is then the case for example, if the piece that circling the axis of rotation of the rear door is conceived in the form of orquilla

According to a following preferred embodiment of the invention is provided, that the rear door has a shaft turn, which is available outside the back door area in funnel shape and outside the area of the shell shaped entry funnel on the back side of the housing or attached to it.

The axis of rotation extends, in this case, in preferential way in the transverse direction of the device steam ironing, so that the back door can be open for example backwards and upwards. The invention without However, it is not limited to that variant. If the axis of rotation is ordered for example in a vertical direction, then let the door rotate rear side. By means of an axis of rotation arranged in an oblique position is allowed to vary on the other hand between a closed and open position. Example: closed state: door rear is in a turned down position; state open: rear door is in a laterally turned position. TO through this form of construction it is possible to turn the lid rear during opening in a position well away from the water filling opening and housing inlet shaped funnel, so that the water filling opening can be very Well achieved for the filling operation.

For the achievement of similar advantages, agree to a more different preferred embodiment of the device ironing, it is planned, that the housing has a part main housing, on whose rear side the entrance is arranged funnel-shaped housing, as well as a rear of housing handle that starts from the main part of housing, and the axis of rotation A of the rear door is arranged on the back of the carcass handle or next to it. This way of construction also allows, when opening the door rear turned in a position well away from the opening of water filling and housing inlet.

Preferably the back door in state closed (partly or completely), it is fitted on the side case back. Thus the back side of the door rear, can function as part of the support surface of the rear side and this function does not affect the rear side.

According to an embodiment variant further advantageous, according to the invention of the device steam ironing, the rear door has an external side, which in closed state of the water filling opening, runs flush or Essentially flush with the back side of the housing. This is an alternative to the above mentioned mode of construction of the back door, which has a rear door area in funnel shape. In this way the back door can contribute to the formation of a large flat surface or a surface of continuous sliding support and also exercise the coverage function for operating elements or housing elements located under the back door and / or form a surface for the set of design elements aesthetic-constructive

According to another embodiment of the device steam ironing, the back door has a side external, whose outer edge areas, in the closed state of the Rear door and water filling opening, extend substantially flush with the back side of the housing. This construction mode is offered especially then if the door Rear, as explained above, is provided with an area funnel-shaped rear door. However, a partial zone of the back door can thus contribute to the support area of the back side

To facilitate the opening and closing of the back door and water filling opening of the device steam ironing respectively, according to the invention, the rear door preferably has a handle element, which is It can be done by hand or with one or more fingers. This element shooter is in its entirety specially shaped at the door rear, for example in the form of one or more elevations and / or bends - and / or cut-outs, incisures, through holes, and / or recoded areas or similar. The pulling element can without however also be planned as a constructive piece separated.

The pulling element is arranged preferably in a section of the back door, which is located between the closure cap and the outer area of the door edge rear The pulling element may thus be arranged for example inside the funnel-shaped rear door area (respectively neighbor to that area) between the closure cap and the outer area of the edge of the back door. The function of the plug closure is not affected by this, in the special case of a door One piece rear, with an integral closure cap.

It has been proven advantageous that the door rear has at least one further embodiment of the invention a locking system, with which the back door, in state closed from the water filling opening on the back side is workable So you can avoid, that the back door, and with it that the water filling opening unintentionally opens, in the case that the closure of the rear door can not only be guaranteed to through a secure enough seat (for example a settlement under detachable pressure) of the closure cap, in the opening of water filling, or when for safety reasons a redundancy.

A further preferred embodiment, according to the invention of the steam ironing device provides that the water tank has a tubular connection hole on the side rear, which is hermetically connectable and communicable with the tubular water filling hole of the housing. For this they are arranged a longitudinal axis of the tubular connection hole, preferably in line with a longitudinal axis of the hole corresponding water filling tubular. The union can have place directly (for example by welding) or indirectly (by example by means of an interconnecting joint sealing element, see below). By means of the rear addressing of the plug closure is technically simple and quick assembly of the union between both construction parts mentioned.

According to another preferred embodiment, of according to the invention of the steam ironing device is provided that the water tank has clamping parts directed towards the back side. This allows you to connect easily the tank with a rear side area of the housing and / or parts located there or auxiliary components. It is also possible easier assembly of the aforementioned parts from the  back side of the steam ironing device.

The water tank according to the invention of the steam ironing device preferably has a reinforcing element, which extends through its hole tubular connection on the rear side, which connects the clamping parts directed towards the rear side. The element of reinforcement is formed on this occasion preferably as a piece integral of the water tank. The reinforcing element can be built in particular with nerves and flat. Can also extend and pass directly through the through opening of the hole. This allows the tank to be strengthened and stabilized. water in the area of its clamping parts, so that he still in case of a lightweight and wall preference construction Thin is very stable. The reinforcing element can be also used as conduction and current stabilization of water during the filling of water in the water tank. Practice with it an advantageous double function.

An especially advantageous embodiment according to the invention of the steam ironing device provides that it has a joint sealing element, which has a (preferably central) water passage opening, which forms the water filling opening, and which forms the closable water filling tubular hole, and the housing water filling tubular hole and the water tank connecting tubular hole are connectable with each other through the joint sealing element. The joint sealing element, at least in the area of its sealing surfaces, is preferably provided with an elastic rubber material. It may additionally have elements of internal and / or external reinforcements, for example reinforcing fibers, iron supplements, an enveloping element or the like. Through the joint sealing element, both sealing and joining functions are allowed to be performed at the same time; It simplifies considerably further the assembly of the water tank and the closing systems belonging to it. The aforementioned bonding sealant element thus exercises an advantageous function.
multiple.

According to a more further preferred embodiment of according to the invention, the joint sealing element is provided with: a first joint and sealing part for the tubular hole water filling; a second part of union and sealing for the tubular connection hole; as well as a plug sealing zone surrounding the water passage opening, into which it is insertable hermetically sealed closure plug to seal the opening of water filling The first and second part of union and sealing simplify the assembly of the water filling tubular hole and of the tubular connection hole, in the construction of the steam ironing device according to the invention, and establishes at the same time a safer hermetic bond between these components. This requires a single work step. By means of the cap sealing area provided in the same piece Mounting for the rear door closing position, it defines the site of the closure plug and guarantees the function of sealed. If necessary, the joint sealant is also interchangeable.

The joint sealing element is structured preferably as a (preferably rubber-elastic; and preferably tubular or shaped ring) plug joint sealing element, which has the following: at first end a first plug opening with the first joint and sealing part for the tubular hole of water filling; at a second opposite end a second opening of plug with the second part of union and sealed for the hole tubular connection; and in an area between the first and the second end, that zone of sealing of cap that surrounds the water passage opening for the closure cap. The element of union preferably has a cross-sectional ring, which Completely formed is adapted to a tubular hole of water filling and a tubular connection hole. Basically the connecting element may however also have other shapes cutting resp. hollow profile shapes, which are harmonized to the corresponding forms of tubular water filling hole and of the tubular connection hole. The internal diameters of the insertion openings are preferably adjusted to the outer diameters of the water filling tubular hole and the tubular connection hole such that these, in a state of complete insertion, with a slight pressure of lace, fit in Insertion openings In the insertion openings or next of them, or assigned to them, can be provided in case of need fixing sets, which secure the hole correspondingly formed water filling tubular complementary and / or the tubular connection hole, also to the joint sealing element. This can be done for example by means of a set of crimping or something similar. With the help of a joint sealant formed in that way, it they leave very easily axially insert each other and join tightly the water filling tubular hole and the hole tubular connection, of the corresponding housing part. This It leads to a lightening and rationalization of the assembly.

The cap sealing area of the aforementioned joint sealing element, preferably forms a stop for the water filling tubular hole and / or the tubular hole of connection, in the insertion direction respectively. This way the positioning of the water filling tubular hole and / or the tubular hole of Connection and precise assembly of this piece is simplified.

And the inside diameter of the sealing zone of cap, is preferably at least smaller than the inside diameter of the water filling tubular hole inserted in the element plug-in connection (but also preferably smaller than the inner diameter of the tubular connection hole). This relationship of diameters ensures that a closure plug can be constructed properly conceived complementary from the rear side, that reaches the plug-in connection element through the hole water filling tubular seated in it and an airtight contact Safe with the cap sealing area.

For the same reason it is also preferred in a following embodiment of the invention, that the closure plug in closed state of the back door extend through the water filling opening and tubular filling hole water and protruding from the end directed towards the water tank of the water filling tubular hole, and that in a sealed way sits across and above the plug sealing area of the plug-in connection element. The shutter can take place here, for example by means of a seat under radial pressure of the stopper of closure in the cap sealing area.

Instead of the previously described element joint sealant or plug-in or plug-in element, can be provided in the steam ironing device according to the invention, basically also the closure cap only with a shutter element. This variant however does not offer then the advantages attainable by means of the joint sealant regarding the multiple function, as well as the union and assembly simplified of the construction parts mentioned above. A variant, in which the closure cap is provided with an element Additional shutter is obviously in the same way possible.

The closure cap preferably has a outer diameter D_ {A}, which is smaller than the inner diameter D_ {i1} of the water filling tubular hole and the opening of water filling respectively, whereby the ratio of diameters D_ {A}: D_ {i1} in an area that reaches 0.75: 100 up to 0.95: 100, especially 0.80: 100, especially 0.85: 100, in Special 90: 100 Since in the steam ironing device of according to the invention, by means of a turning movement of the rear door, the closure plug must be brought into position closing, and the water filling opening to its closing state hermetic, ensures the aforementioned ratio of diameters, that the closure plug at a preconceived distance between the axis of rotation of the back door and the center of the filling opening, during the turning process, do not collide with the inner edges of the water fill opening or stay suspended there. In case if an element is used as a joint sealant plug-in sealant of the type described above, the The aforementioned relationship of diameters also ensures that the element joint sealant is conceived sufficiently stable and adjusted to different (preferably equal) diameters outside of the water filling tubular hole and the plug closure, as well as the outer diameter of the closure cap, in such a way that a) secure union is achieved on the one hand and airtight, especially towards the water filling tubular hole, and b) on the other hand the closure plug securely and shutter, but also easily removable again and again, it can be inserted respectively introduced, without thereby plug-in connection element next to the plug sealing zone be radially too widened and the joint is affected airtight between the water filling tubular hole, as well also the tubular connection hole.

According to a preferred following embodiment of the ironing device according to the invention, it has the housing a rear housing opening as well as a plate rear housing with which the rear housing opening is closable, and in which the tubular orifice of water filling with the closing water filling opening; the In this case, the rear housing plate accommodates the rear door. The back door must not be necessarily structured as a piece of completely flat, plate-shaped construction. The part exterior of the back plate is in principle, however, preferably flat, so that it can also work well as a support surface of the housing. The interior of the housing is easily accessible by the rear opening of the housing, which facilitates assembly or repairs. Plate rear housing including the rear door and all elements belonging are left premanufactured as a module, which simplifies and rationalizes the production of these components and their subsequent assembly. The back cover plate may be structured as a separate piece from the rest of the housing, or also but as an integrated manufacturing part, which can be manufactured in a working step, for example in the injection (of plastic), together with another part of the housing. Back plate It is preferably conceived as an easy piece to disassemble again. She may however also be built so that after assembly forms a fixed unit with the rest of the housing and then only destroying it can be separated from housing assembly.

The back cover plate features preferably with the holding parts of the water tank corresponding fastening means (eg screws, rivets, bolts, adhesion means, fitting joints, or the like), with which the back cover plate is connectable to the tank of water, and through it connectable with the rest of the housing.

In a preferred embodiment of the device steam ironing according to the invention, the fastening means in closed state of the water filling opening are covered by the back door. That way the clamping means are better protected against external influences. This way of build enables at the same time a special aesthetic design of the ironing device.

And finally presents the device steam ironing in another more preferred embodiment of the invention, a retention system to hold temporarily the rear door in a fully open position. The function Retention can be performed by means of integrated elements or separated, corresponding to each other, attached to the door rear and / or to the housing, which support the back door in its fully open position, by means of friction and / or shape (eg through resting elements). If desired, these types of elements can naturally be provided as well for intermediate rear door positions.

A preferred embodiment of the invention with added design details and other advantages, it is located then taking into account the attached drawings described and clarified in depth.

Description of a preferred embodiment

In Fig. 1 it is shown, in a view schematic of a longitudinal section, a steam iron 2 of according to the invention, in an appropriate position for filling with water W, put head. The longitudinal direction, direction transverse and vertical direction of the steam iron 2, this designated in the drawings in a Cartesian coordinate system with the reference symbols X, Y and Z. The steam iron 2 has a housing 4 in several plastic parts, with a main part of housing S1 and a handle 6 in the form of stirrup that starts from she. The lower front grip bridge 6a, is formed in the description according to Fig. 1 by a front part of S3 housing handle and rear rear handle bridge 6b by a back of housing handle S2. The side rear of the back of housing handle S2 together with the back side of the main housing part S1 forms in essentially a flat back H of the housing 4.

The back side H works among other things as a support surface configured to place on it, the steam ironing device 2. This type of conformation of housing 4 also has a rear housing plate 8 (hereinafter, denominated in abbreviated form, back plate 8) of plastic, the which extends essentially over the full rear side H and closes a rear case opening. On this back plate 8 and with it on the rear side H a tubular orifice of water filling 10 with a water filling opening 10a. The back plate 8 features a funnel-shaped housing entry 12, with a funnel-shaped tubular hole centered in the direction  transverse, which forms the aforementioned tubular filling hole of water 10 with the water filling opening. The tubular hole water filling 10 has a diameter of tubular shaped section of circle The funnel-shaped housing entry 12 extends over almost the entire surface of the back plate part 8, the which is arranged in the main housing part S1.

A water tank 14 of the steam iron 2 constructed with plastic is arranged in such a way that the same extends partly inside the housing 4 and partly (that means here, with the lateral and frontal and upper areas), it also forms external surfaces of a basic plate housing water tank envelope 14 (see also Fig. 2 and 3). In water tank principle 14 could naturally also be fully integrated in the housing. Water tank 14 has a tubular connection hole 16 on the rear side in the form of tube with a circular tubular diameter. The inner diameters and outside of the tubular connection hole 16 and the tubular hole Water filling 10 are in this case the same size, they may, however, also be different; It is however preferential, that at least the internal diameters are equal. By means of the tubular connection hole it is connected in a way hermetic and communicating the water tank 14 with the hole water filling tubular 10 of the back plate 8.

This hermetic union takes place by means of a joint sealing element 18, shaped like a tube or ring, which it has a tubular central water passage hole, which forms the 10a water-filled tubular opening. The element joint sealant 18 is completely or essentially constructed full of a rubbery elastic material, for example with an elastomer. This has a first part of union and sealed 18a for the water filling tubular hole 10 and a second joint and sealing part 18b for the tubular hole of connection 16. It also consists of a plug sealing area 18c surrounding the tubular water passage orifice respectively to tubular water filling hole, in which a plug of seal for closing the water filling opening is insertable In the present embodiment example, the element joint sealant 18 is formed as a sealant element of symmetric plug-in union of tubular or ring form. In the opposite ends respectively of this sealing element of plug-in connection 18 are inserted, plugged, the tubular hole connection 16 and the water filling tubular hole 10. Other characteristics related to the object and functional of this element plug sealant 18 are described below more in detail.

In the drawing presented in Fig. 1 is the water tank 14 partially filled with water W.

The steam iron 2 according to the invention It also has a revolving rear door 20, fixed on the rear side H of the plastic housing 4. The back door 20 It is equipped with a fully formed closure cap 22, with which the water filling opening 10a rear is closable. In the present embodiment of the rear door 20 is received by the back plate 8 of the housing 4. The rear door 20 has a funnel-shaped rear door area 20a (see also Fig. 2), the one that extends from an edge area of the back door 20, which is arranged in the main housing part S1, to its closure cap.

Fig. 1 shows the rear door 20 in a state full opening respectively uncovered, in which also the water filling tubular hole 10a is open. The axis of Turn A of the rear door 20 extends transversely Y or parallel to him. As can be recognized in Fig. 1, this arranged the axis of rotation outside the rear door area in funnel shape 20a and outside of the casing entrance in the form of funnel 12 in an area of the rear door 20, which is located in rear door mounting state 20, at the rear of S2 housing handle. The lateral distance of the axis of rotation A from the center of the water filling opening 10a reaches approximately twice the inside diameter of the opening of water filling 10a. The axis of rotation A is located for this reason quite far from the water filling opening 10a. In state uncovered is therefore the rear door 20, together with its closure cap 22, next to the filling opening of water and funnel-shaped housing inlet 12. The area terminal 20b of the rear door 20, which is assigned to the axis of rotation A, is deposited in a cavity 8a of the back plate 8 (see especially also Fig. 7).

The rear door 20 is also equipped with a locking system 26, with which the rear door 20 is workable to the rear side H, in the closed state of the filling opening of water (compare Fig. 3). This locking system 26 is designed in this example as a detachable hitch assembly, with a latch hitch 26a, which is at the opposite end of the door rear 20 belonging to rotation axis A and a counterpart of the latch latch 26b on back plate 8, or vice versa.

Fig. 2 shows a schematic view in perspective of the steam iron in Fig. 1, with a view at its side H rear and bottom side. More details are recognized in this drawing of the steam iron 2 according to the invention. It can be seen, that part of the back door 20, which is assigned to the main housing part S1 (see Fig. 1) and containing the funnel-shaped rear door area 20a, configured with a large area very wide. That part or terminal zone 20b of the rear door 20 instead, which extends towards the axis of turn A and that is assigned to the rear handle of housing S2 (see Fig. 1), is relatively narrow for this purpose. small and shaped surface in the form of tongue or lever, to that she can be integrated well into that part of the housing 4 respectively on the back plate 8 and especially in the cavity 8a.

As it derives in addition to Fig. 2, the door rear 20 has to open and close a pulling element 24 in shape of a simple passage opening, which is arranged in a rear door sector 20, which is between the plug closure 22 and the edge area of the rear door 20 in the area funnel-shaped rear door. The function of the plug closure 22 is not because of it in any way affected.

The back plate 8 is joined by two screws 28, which pass through two openings provided on the sides of the water filling opening, screwed with two holding parts 30 of the corresponding water tank 14, directed towards the rear side H (see for this Fig. 6) and with it connected by means of the water tank 14 with the housing 4. The screws 28 or parts, which are arranged thereto, may be provided with a shutter and waterproof medium, so that through the screw connection cannot absolutely penetrate water into the inside the housing 4. In addition there is the back plate 8, in the upper end area of rear handle bridge 6b, attached also by means of a plug-in connection, which because of a better Clarity has not been represented in the drawings.

Fig. 3 shows a longitudinal view schematic through the steam iron 2 in a state in which the water tank 14 is filled with water W and the back door 20 and with it also the water filling opening is completely closed. The steam iron 2 is in a position respectively appropriate arrangement for steam ironing. Fig. 4 is a schematic perspective view of the steam iron 2 of Fig. 3 with a view of its closed rear door 20.

As is evident in Fig. 3, is the door rear 20 in a state of complete closure, fully inserted in the rear side H of the housing 4 and received by the rear plate 8. As you can well recognize about this in Fig. 3, it runs flush of the contour of the funnel-shaped rear door area 20a in the closed state of the water filling opening and the door rear 20 in principle parallel along the outer contour of the housing inlet 12 of the back plate 8 respectively on the rear side H. The closure plug 22 is in this position directed towards the water tank and introduced into the zone of plug sealing 18c of the plug-in joint sealant 18. In addition the areas surrounding the edge areas of the outer side of the rear door (20) run flush with the rear side H of the housing 4 respectively of the back plate 8 (see also Fig. 4). If the back plate 8 did not present zone 20a, it could thus the entire outer side of the rear door be formed 20 for example flat, so that all that outer side of the rear door 20 then run flush with the rear side 8 of the housing 4 respectively of the rear side 8. As is evident  also in Fig. 4, the screws 28 (compare with Fig. 2) in state closed from the water filling opening respectively of the back door 20 are completely covered by the back door twenty.

Fig. 5 shows a longitudinal view enlarged schematic, through the joint sealing element plug-in 18, according to the invention of the steam iron 2. As evidenced by this drawing, it has the joint sealing element Pluggable 18 a basic body in the form of a tube or ring. In a first right end shows the joint sealing element plug-in 18 a first plug opening with the first part sealing and joining 18a for the water filling tubular hole 10. In addition, this has a second left opposite end, a second plug opening with the second sealing part and junction 18b for the tubular connection hole 16. The diameter inner DS_ {i1} of 18a is slightly smaller than the diameter outside D_ {A1} of 10, that means DS_ {i1} <D_ {A1}. And the  inner diameter DS_ {i2} of 18b is slightly smaller than the outer diameter D_ {A2} of 16, that means DS_ {i2} < D_ {A2}. The water filling tubular hole 10 and the hole tubular connection 16 are supported by penetrating with its perimeter is say with a slight seat pressure on the sealing element of plug-in connection 18.

In an area of the joint sealant plug-in 18 found between the first and the second end as well as also between 18a and 18b the plug sealing zone is provided 18c for the closure cap 22 surrounding the passage opening of Water. The plug sealing zone 18c is formed as a ring inside the basic body of the sealing element of plug-in junction 18, formed inward with a protrusion projection 32 and has a perimeter of the inner surface rounded 32a or domed. This perimeter configuration of the rounded inner surface 32a simplifies during a closing procedure insertion respectively introduction of the closure cap 22 and achieves a better sealing seat. By the same reason may the closure plug 22 be shaped in its front end for example rounded or slightly tapered.

In the projection 32 in the form of a zone ring plug sealing 18c may for example be an element integrated reinforcement, which prevents the closure plug 22 from widening too radially the left and right areas of the first and second sealing and joining part 18a, 18b of the hole water filling tube 10 and / or lift the tubular hole of connection 16 and thereby affect the bonding and sealing effect between This parts. An optional reinforcing element of this type is especially recommended then in the case that the element of plug-in junction 18 has only reduced wall thicknesses.

As illustrated below in Fig. 5, the side walls 18c1, 18c2 right and left of the area of plug sealing 18c, in the drawing, form in each case, in the direction of introduction hinted by means of arrows, a stop axial for the water filling tubular hole 10 and the hole tubular connection 16. And that areas 32b of the sealing zone of cap 18c associated laterally to the rounded surface interior perimeter 32a are shaped in labial form and constitute respectively with the opposite radial surface interior perimeter of 18a, 18b a kind of plug-in channel 32c

That respective external diameter DS_ {A1}, DS_ {A2} assigned to zone 18a, 18b about 32a is at least more larger than the respective inner diameter D_ {i1}, D_ {2} of 10 resp. 16, e.s. DS_ {A1}> D_ {i1} and DS_ {A2}> D_ {i2}. When the water filling tubular hole 10 and the hole tubular connection 16 in the plug-in joint sealant 18 and its above introduction channel 32c are plugged in, it seat lips 32b in the respective inner perimeter of the water filling tubular hole 10 and the tubular hole of connection 16. And those parts are also introduced with their interior perimeter surfaces with a slight pressure of seat in the plug-in joint sealant 18. This increases Bonding and sealing efficiency.

The inner diameter DS_ {i} of the area of cap sealing 18c is smaller than the respective equal diameter D_ {i1}, D_ {2} of the water filling tubular hole 10 and the tubular connection hole 16 in this example. When you are pieces are joined together by means of the sealing element of plug-in connection 18 and communicating, protrudes from the surface rounded interior 32a with its perimeter projection 32 in the form of ring, therefore also inward on the perimeter inside, respectively inside diameter of those pieces.

The outer diameter D_ {A} of the closure cap 22 is no smaller than the inside diameter D1 of the hole water filling tube 10, that is D_ {A} <D_ {i1}. The ratio of diameters D_ {A}: D_ {i1} is in this case approx. 0.86: 100. By closing the back cover 20, the closing cap 22 can therefore protrude above the end directed towards the water tank 14 of the water filling tubular hole 10 in through shape through the water filling opening (see Fig. 3) and that in the closed state of the back door 20 is inserted plug in the sealing zone of cap 18c. The effectiveness of shutter is achieved here in principle by a slight radial seat pressure of the closure plug 22 on the projection in ring shape 32 and on the inner perimeter surface 32a. For it is the inner diameter of 32 slightly smaller than the outer diameter DA of 22, ie DS_ {i} <D_ {A}. In certain accounts are worth it for the closure cap 22 the concerning in this case decisive relations of diameter: DS_ {i} <D_ {A} <D_ {i1}.

A view is shown in Fig. 6 back schematic of the water tank 14 with an end view assigned to the rear side H (see for example Fig. 1). It is recognizable,  that the water tank 14 has by its tubular connection hole 16 on the rear side a reinforcing element 34 that runs integral with nerves, in the form of plaque which crosses through the tubular orifice opening and joins between them those parts of clamp 30 directed towards the rear side, which are assigned to the back plate 8. The clamping parts 30 are formed here respectively as a thickening of material in the form of cylinder of the reinforcing element 34, in which it is provided respectively a simple blind perforation. In drilling Blind is the respective screw 38 (see Fig. 2) screwable with own cutting thread.

Fig. 7 shows a schematic sectional view of through the steam iron according to the invention in the area of the pivot shaft A of the rear door 20. The device steam ironing has a support and retention device 36 for the retention or temporary support of the rear door 20 in a fully open position. This retention system 36 is conceived in the exemplary embodiment as follows. That area terminal 20b of the rear door 20 seated in the cavity 8a of the back plate 8 has an elbow 20c to which it joins respectively by means of a cut a side wall 20d. On the side wall 20d a ball joint bolt 38 is inserted respectively, which forms the rotational settlement of the rear door 20 which establishes the axis of rotation A. In the wall of the cavity 8a is in shape integral formed a projection 40. The distance between the axis of turn A and the one chosen in Fig. 7 lower edge of elbow 20c is of such that the elbow 20c shortly before the full opening resp. uncovering position of the rear door 20 knocks lightly against the ledge 40. The rear door 20 is now turned on the full opening position, the elbow 20c is run over the projection 40, which now presses against the lower side of the elbow 20c, this twists slightly and reversibly towards above and thus the rear door 20 is held by means of a friction and hitch joint. Instead of a hitch joint it could naturally be used a lock joint easily repeatedly removable. They are also realizable systems of non-mechanical retention, for example a retention system magnetic.

The steam iron 2 according to the invention account among others, as is common in steam irons, of a evaporation chamber communicable with water tank 14, which is assigned to a heated ironing sole 42 (see e.g. Fig. 1) with steam outlet perforations. For heating of the ironing sole 42 as well as for steam production of water in the vaporization chamber is provided a set of electric heating, which in this example is integrated into a metal structure of the ironing sole 42 and through a cable 44, which exits the housing 4 on the upper side of the handle bridge 6b, is powered by electricity. In place of an electric heating assembly can obviously any other heating set should be used, such as e.g. also catalytic or chemical heating assemblies or sources External heat The steam iron 2 is also equipped with regulating assemblies as well as operating elements, for example with a temperature regulating set and adjustment element of temperature, a set to spray with a spray button, a steam quantity adjustment set, a push button of steam, etc.

Fig. 8 shows a schematic view longitudinally through a plug-in connection element 18 of according to a second embodiment. The fundamental concept of this variant resembles that of Fig. 5. The protrusion 32 ring-shaped assigned to closure cap 22, however laterally extended completely out, it is different as in this one. In this type of design is therefore not necessary (as represented in Fig. 3), that the closure plug 22 exceeds through the hole water filling tube 10 and on its end directed towards the water tank 14. The true sealing area for the plug of closure 22 may for this reason be located viewed at your address embedded / inserted can therefore be located also before the end of the water filling tubular hole 10.

The invention is not limited to the current example. of realization, which only serves to explain in a general way the central thought of the invention. In the framework of protection of the appended claims, the device according to the invention may rather take still others to those specifically above Described design forms. Especially can the handle Present other shapes or configurations. This is possible, for example. conform a handle with only a handle bridge. The construction of the back side of the steam iron according to the invention may hereinafter correspond to the embodiment described above. On the contrary, a handle is used that consist only of a front bridge and / or middle bridge, the construction of the rear door must be adapted poorly and its axis of turn transferred to the main part of the housing.
