EP2602554B1 - Door for a domestic appliance, domestic appliance with a door and method for mounting a door profile - Google Patents

Description

The invention relates to a door for a household appliance, with an outer pane, on whose insides at least one elongated door profile is arranged. Furthermore, the invention relates to a household appliance with such a door as well as a method for mounting a door profile on an inner side of an outer pane of a door of a household appliance.

Oven doors are known in various designs. Thus, it is known in this context that such doors have a plurality of separate plates oriented parallel to each other at least partially transparent plates, which are referred to below as slices. Thus, in this context, an outer pane, which is also referred to as a windshield, is provided. In addition, a door at least also includes a second disc, which is referred to as an inner pane and is positioned facing the cooking chamber. These at least two panes of a door are spaced apart from each other by door profiles and held. Moreover, it is also known that doors may have at least a third disc, which is then arranged between the outer pane and the inner pane. Between the at least two discs is the technical structure of the oven door, which can vary. The windows and the technical structure are connected to the device by supporting door components, namely the door profiles. These door profiles are elongate parts which are spaced apart parallel to each other on the inside of the outer pane attached. This attachment or connection can be made cohesively, which is carried out for example by a direct bonding of the components. In addition, a frictional or positive mounting of the components can be done on already provided connection parts on the discs.

Requirements placed on future oven doors are ever more extensive. This relates in particular to the temperature resistance of these discs, in particular the windscreen, so that they must not heat above a predetermined temperature in order to prevent injury to a user. In addition, are current structures relatively inexpensive and also consuming installation. In addition, other known mounting variants in which the door profiles are bolted to connecting parts on the outer pane, very prone to position tolerances that are undesirable. In this regard, displacements of the windshield relative to the door profiles in the longitudinal direction of the profiles may result. By screwing a sufficiently accurate positioning of the components in this longitudinal direction of the profiles can not be reliably guaranteed.

Relevant prior art is in the DE102004005929 A1 and EP2551601 A2 to find. It is an object of the present invention to provide a door for a household appliance as well as a method for mounting a door profile on a window of the door, with which or with which the assembly can be done sparing and still very accurate position the attachment of the door profile is achieved. It should also be created a household appliance with a corresponding door profile.

This object is achieved by a door, a household appliance and a method according to the independent claims.

A door according to the invention for a household appliance comprises an outer pane, on the inside of which at least one elongate door profile is arranged. At least one receiving frame is arranged on this inner side, in which, in the mounted state of the door profile on the outer pane, a holding bar arranged on the door profile for holding the door profile on the outer pane extends into it. By such a configuration, a very accurate and positionally secure attachment of the door profile can be ensured on the outer pane. In addition, the assembly effort is significantly reduced.

As a mounting frame or support frame embodiments are understood to be circumferentially closed. Likewise, however, it also includes designs that are not closed all round. In particular, embodiments may also be included, which are formed over the circumferential length at least over half, in particular three quarters.

The very specific embodiment of the door profile, namely with at least one retaining bar, allows in a defined manner with the mechanical coupling of the door profile another separate component, namely the receiving frame, which is fixed to the inside of the outer pane. Because virtually by the holding bar and the receiving frame two in terms of their geometric shape and functionality very specifically designed elements are formed and it is also achieved by the active connection, a mechanically stable holder. In addition, a very weight-reduced component is provided by the design of a receiving frame, which, however, is designed to be secure and reliable for receiving the retaining bar. By virtually a simple insertion or insertion of the retaining bar in the free space of the receiving frame attaching the door profile can be achieved on the outer pane. The assembly is thus very smooth and clear and quick to perform.

In particular, it is no longer necessary to secure the door profile by additional screws, so that in particular a screwless installation of the door profile is ensured on the outer pane.

The receiving frame is characterized in one embodiment in that it is fully encircling and thus closed, so that the retaining bar is fully encompassed in the assembled state of the door profile of the receiving frame in its circumference.

It is preferably provided that the retaining bar is arranged in a recess formed on a longitudinal side wall of the door profile. By such an arrangement, a very compact and space-saving arrangement is created because the retaining bar is quasi quasi inside the door profile. It is thus carried out on a longitudinal side wall of the door profile, a material recess to the effect that on the one hand forms a free space, on the other hand, however, defined therein the holding bar is arranged in terms of its shape and orientation.

Just by this configuration, that forms the retaining bar in a longitudinal side wall of the door profile and is virtually accessible to this longitudinal side wall to the outside, a very specific mounting scenario with respect to a direction of insertion of the retaining bar in the receiving frame in an angle, in particular perpendicular, allows the longitudinal axis of the door profile become. As a result, in a very specific and highly functional manner, a position fixation on the one hand in the longitudinal direction of the door profile and on the other hand in an axis perpendicular thereto, which then also perpendicular to the outer pane, can be achieved.

It is preferably provided that the receiving frame is at least partially received in the mounted state of the door profile on the receiving frame in the recess. The advantages mentioned above are thereby further favored. In addition, by this quasi-sunk in the door profile arrangement of the receiving frame on the one hand this space-saving, positionally reliable and protected from damage.

It is preferably provided that the free space between the holding beam and the walls delimiting the recess is designed for accurately fitting receiving part walls of the receiving space. This embodiment is particularly advantageous in that an undesirable movement play of the door profile in the state connected to the receiving frame is thus prevented.

In particular, it is provided that the recess formed in the longitudinal side wall, in which then the holding beam is arranged, is freely accessible via the longitudinal side wall to the outside. Precisely because of this, the insertion of the door profile into the mounting frame is ensured in a particularly easy-to-understand manner for an installer, so that a particularly user-friendly installation is also provided here.

It is preferably provided that the cross-sectional shape of the retaining bar is adapted to the shape of the receiving frame at least in the intended area for engagement in the receiving frame portion, in particular adapted for precise insertion into the receiving frame. Again, thus the above-mentioned position-safe and backlash-free assembly can be guaranteed.

It can be provided that the cross-sectional shape of the holding beam is square, in particular quadrangular, for example rectangular or square. In this context, it is also advantageous if the receiving frame has the analog shape. However, it can also be provided that the holding beam has a corner-free cross-sectional shape and thus, for example, is designed round or oval.

Likewise, a free form may be formed as a cross-sectional shape. Due to the cross-sectional shape, a coding of the retaining bars can also be formed in a specific manner, so that in a complementary embodiment with the receiving frame and incorrect assembly can be avoided.

In particular, it is provided that the retaining bar is formed integrally with the door profile, so that here is a component-reduced design is created. In addition, a very positionally secure arrangement of the retaining bar on the door profile is achieved permanently, which may not be reliably ensured when mounting a separate holding bar on the door profile. In addition, an additional separate mounting of the retaining bar on the door profile is not required. It is preferably provided that the receiving frame is arranged with its opening to its longitudinal side wall of the door profile and an insertion direction of the door profile in the receiving frame with the holding beam is perpendicular to the longitudinal axis of the door profile. The above-mentioned position assurance of the door profile in the direction of its longitudinal axis is thereby particularly favored. According to the invention, the front free end of the retaining bar is maximally flush or set back from the longitudinal side wall. A projecting beyond the longitudinal side wall to the side outward of the retaining bar is thereby avoided, so that no unnecessary space for the retaining bar is needed.

It is preferably provided that the retaining bar is formed in a straight line. A particularly smooth assembly and introduction into the mounting frame is achieved.

It is preferably provided that the holding beam, in particular with its longitudinal axis, extends perpendicular to the longitudinal axis of the door profile. This is particularly advantageous in that an insertion direction during assembly of the door profile on the receiving frame or receiving frame is thus ensured, which is oriented perpendicular to the longitudinal axis of the door profile. In particular, this insertion direction is then arranged in a plane which is oriented parallel to the plane of the outer pane.

It is advantageous that the receiving frame is glued to the inside of the outer pane. Since the receiving frame is a relatively small compared to the door profile component, just such a fastening can be generated quickly and with little effort and little adhesive.

It can be provided that the retaining bar is arranged locked in the receiving frame in the mounted state. By such a specification, in addition to the already achieved position fixation in the direction of the longitudinal axis of the door profile and in a direction perpendicular thereto, which is also perpendicular to the outer pane, the position fixation can also be achieved in the third spatial direction, namely in the direction of the longitudinal axis of the holding bar become. In particular, with the latching a release of the components in the joining direction is prevented.

It is preferably provided that the receiving frame is formed on a receiving part, which is in particular plate-like. As a result, a flat construction and as large as possible applied to the inside of the door glass design is possible.

Preferably, the receiving part is then attached to the inside of the door glass, in particular glued.

Preferably, a positioning element is arranged on the receiving part. As a result, a position assurance of the door profile when attaching to the receiving frame in the direction of the longitudinal axis of the door profile done. The positioning element is arranged in particular spaced from the receiving frame. It is formed in particular sword and protrudes from the receiving part upwards.

Preferably, the door profile has a slot-like receptacle for the positioning element on the longitudinal side wall, on which the retaining bar is formed.

In addition, a non-destructive reversible assembly and disassembly is easily possible by such locking, which can be accomplished easily and quickly.

Preferably, in this regard, it is provided that, for example, a latching element is arranged on the holding bar, which can be designed as a latching tab or protruding latching lug. In a complementary embodiment can then be formed in the receiving frame at least on a side wall a recess as a locking receptacle.

It is preferably provided that a further functional part, in particular, for example, a door hinge and / or an edge termination element and / or a design part, is attached to the mounting frame. As a result, a multifunctionality of the recording frame can be generated.

Furthermore, the invention relates to a household appliance, in particular an oven, with a door according to the invention or an advantageous embodiment thereof.

Preferably, the door is provided for closing a cooking chamber of the household appliance, wherein it may be positioned both laterally and down struck.

Furthermore, the invention relates to a method for mounting a door profile on an inner side of an outer pane of a door of a household appliance. The door profile is inserted into an assembly direction directed at an angle, in particular perpendicular to the longitudinal axis of the door profile, with a holding beam arranged on the door profile in a receiving frame arranged on the inside of the outer pane for holding the door profile on the outer pane.

By the lateral sliding of the door profile a clear fixation of this can be achieved with the outer pane in the main spatial directions, namely the longitudinal direction of the door profile and in particular perpendicular thereto, in this regard, the two spatial directions span a plane extending parallel to the plane of the outer pane , The main loads, which are relevant for a oven door, burden the structure in the respect to this third perpendicular spatial direction, which is then also oriented perpendicular to the plane of the outer pane. The decoupling of the joining direction and of the loading direction has further potentials by possible optimizations of the component geometry. Through an optimized Design of the connection components can also be a best possible determination of the door profiles are ensured in the direction of the longitudinal axis of the door profile. A detailed cutout in the door profile, which represents the retaining bar, is pushed onto a molded tab or a holding frame. To reduce the variation, it is advantageous to be able to use this mounting frame several times in the construction of a oven door and this as already mentioned above, to assign additional functionalities in which it serves as a connection or recording for other functional parts. By the invention, a lateral offset of the design column or a tolerance-related reduction of the function column, such. B. ventilation cross sections are prevented. In addition, by using the same small support frame, which are glued in particular, which in turn can integrate many functions, a variant-optimized design can be done. This also brings cost advantages through installation savings and low correction effort to map critical dimensions.

In the figures, identical or functionally identical elements are provided with the same reference numerals.

In Fig. 1 is shown in a schematic representation of a trained as a baking oven 1 household appliance. The oven 1 comprises a cooking chamber 2 which is bounded by walls of a muffle 3. The muffle 3 has on the front side a charging opening, which can be closed by a door 4.

In terms of number and position shown by way of example only, the oven 1 comprises cooking zones 5, 6, 7 and 8. In addition, a display unit 9 and operating elements 10 and 11 of an operating device are likewise provided with respect to number and position by way of example only.

In the exemplary embodiment, the door 4 is struck down and pivotable about an underlying horizontal axis.

In Fig. 2 is a perspective view of the door 4 in the assembled state shown. In the exemplary embodiment, the door 4 comprises a front plate, which is formed as an outer pane 12 and at least partially made of glass, in particular completely made of glass. The outer pane 12 is arranged facing away from the cooking chamber 2 in view of the structure of the door 4.

In addition, the door 4 comprises a spaced apart and arranged parallel to the outer pane 12 inner pane 13. This is also preferably formed of glass and as shown in FIG Fig. 2 designed in the embodiment with smaller dimensions than the outer pane 12th

It can also be provided that at least one further third plate in the form of a disc is present, which is then designed as a washer and between the outer pane 12 and the inner pane 13, which faces the cooking chamber 2, is arranged.

In the exemplary embodiment, the outer pane 12 and the inner pane 13 are connected to one another by a first door profile 14 and a second door profile 15. The door profiles 14 and 15 are elongated and rectilinear supports which are fixed to the outer pane 12. For attachment is below the Fig. 3 shown.

On an inner side 16 of the outer pane 12 in the exemplary embodiment, two holders or receiving parts 17 and 18, each having a receiving frame 19 and 20, attached, in particular glued to the inner side 16. These receiving parts 17 and 18 and in particular the receiving frame 19 and 20 are relatively small parts, which are thus designed to save weight and are easy to install. They are arranged at a distance from one another and arranged on a straight line which extends in particular parallel to a side edge 12a of the outer pane 12. It can also be provided that the receiving frames 19 and 20 are arranged at different distances to the side edge 1a and thus offset.

In Fig. 3 For reasons of simplicity and clarity, only the area of the outer pane 12 is shown on which the door profile 14 is then arranged. The design, construction and installation of the door profile 15 on the inside 16 is analog.

As from the illustration in Fig. 3 can be seen, the receiving frames 19 and 20 are rectangular and extend in a plane which is oriented perpendicular to the plane in which the outer pane 12 extends. In particular, this is the xz plane in the exemplary embodiment.

The receiving frames 19 and 20 are also oriented so that their openings 21 and 22 are oriented perpendicular to the connecting line between the receiving frame 19 and 20 and thus in particular in the x-direction are open and accessible.

The door profile 14 has on a vertical longitudinal side wall 23, which faces away from a lateral edge 12a of the outer pane 12, recesses 24 and 25 open to the side. In these recesses 24 and 25 each have a holding beam 26 and 27 integrally formed, so that the door profile 14 is integrally designed with these holding beams 26 and 27.

The support beams 26 and 27 are in the embodiment in cross section rectangular and thus adapted to the shape of the openings 21 and 22 of the receiving frame 19 and 20.

In particular, it is provided that the geometry of the holding beams 26 and 27 for accurately fitting insertion into the openings 21 and 22 of the receiving frame 19 and 20 are configured.

In addition, it is provided that a free space 28 (FIG. Fig. 4 ), which is dimensioned between a retaining bar 26 or 27 and the walls defining a recess 24 or 25 so that a receiving frame 19 or 20 can be inserted or sunk therein. Preferably, the free space 28 can also be designed such that a precise fit of a receiving frame 19 or 20 is made possible.

As well as from the illustration in Fig. 3 can be seen, a longitudinal axis A of the support beam 26 extends in the x-direction and thus perpendicular to the longitudinal axis B of the door profile 14. In a corresponding manner, the support bar 27 is oriented.

In particular, it is also provided that at least one retaining bar 26 and / or 27 at least one in Fig. 3 not shown locking element is arranged. This can engage in the assembled end state of the door profile 4 on the receiving parts 17 and 18 in locking receptacles. By way of example, a locking receptacle 29 on the receiving frame 19 in Fig. 3 shown. In this case, a recess or a hole in a vertical boundary wall of the receiving frame 19 is formed, in which then snap the locking element 26 on the support bar or can lock. The analogous can then additionally or instead be provided on the receiving frame 20 and on the holding bar 27.

It can also be provided that a receptacle for a hinge or another functional part is formed at the location of the latching receptacle 29. The locking can then be formed elsewhere. For example, a latching encompassing of the holding bar 26 facing away from the edge of the receiving frame 19 can then take place. Fixing of the door profile 14 or 15 can also take place in such a way that the vertical walls of the receiving frame 19 or 20 engage or latch with the door profile 14 or 15.

As in Fig. 3 can be seen on each receiving part 17, 18 adjacent to a respective receiving frame 19, 20 spaced from a positioning member 30 is formed. These are upstanding plate parts. They are inserted in slots 31 in the longitudinal side wall 23 when assembling the parts. As a result, the door profile 14 is fixed in the direction of its longitudinal axis A. The slots 31 are spaced from the recesses 24, 25 formed.

In Fig. 4 is a sectional view of the embodiments in Fig. 3 shown along the section line IV-IV. The illustrations in 3 and 4 show the disassembled state. In Fig. 4 It can be seen that an end face or a front free end 30 of the retaining bar 26 does not extend beyond the longitudinal side wall 23 in the x-direction, but is, for example, flush therewith.

Starting from the state in 3 and 4 is for mounting the door profile 14 of this in an insertion direction, which is oriented in the x-direction, laterally pushed or inserted onto the receiving frame 19 and 20, so that the holding beams 26 and 27 at least partially hineinerstrecken in the openings 21 and 22. The mounting direction or insertion direction thus takes place in the x direction and thus in a plane which extends parallel to the plane of the outer disk 12 and represents the xz plane.

In the following, then the inner pane 13 can be arranged on the upper sides of the already mounted on the outer pane 12 door profiles 14 and 15, for example, be glued.

Alternatively, it could also be provided that the door profiles 14 and 15 also have corresponding further holding beams, which are formed and oriented analogously to the holding bars 26 and 27, so that the assembly of the inner pane 13 takes place analogously to the door profiles 14 and 15. In such an embodiment, it is advantageous if first a door profile, for example, the door profile 14 is mounted on the outer pane 12, subsequently the inner pane 13, on which on the outer pane 12 side facing also corresponding brackets 17 and 18 are formed, and inserted optionally locked. In the following can then be mounted on the opposite side of the door profile 15 and thus simultaneously connecting the door profile 15 with the outer pane 12 and the inner door pane 13 are performed.
