Description

Door for a household appliance and household appliance for preparing food with a door

The invention relates to a door for a household appliance, with a first door pane and a second door pane arranged at a distance therefrom, and a panel which is arranged as covering of edges of the door panes at least in regions. Furthermore, the invention relates to a household appliance for preparing food with such a door. In household appliances for preparing food, such as an oven, it is known that a door for closing a cooking chamber of this household appliance has a plurality of door panels. In this context, doors are known which have at least one door outer pane and a spaced apart and parallel inner door panel. The door inner pane is arranged closer to the cooking chamber in the closed state of the door than the

Door outer pane.

In addition, doors of such household appliances are known which arranged at least one between the door outer pane and the door inner pane

Door intermediate disc include, which is also spaced and parallel to the door outer pane and the door inner pane is arranged.

Usually, the door panels are held by elongated door profiles, which are also spaced apart parallel to each other at a rear or inside of the door outer panel are attached. A so-called top panel forms the upper end of the disc package and covers the upper horizontal edges of at least some of the door panels, in particular all the door panels of the door. The top panel is designed as a separate component. It comprises in known embodiments openings through which air flowing in the spaces between the door panes can flow out.

Such a disc package of a plurality of door panels is also to store accordingly. Since the door windows are relatively heavy, the storage is to design accordingly. Since the door is usually a pivoting component of the household appliance, occur in conventional designs of the bearings

unwanted noise that occurs due to the tolerance-related design of the bearing components, if then a certain lifting and again

Striking the door glass occurs on these storage components. In addition, at present, the configuration of the storage is formed such that they are separate parts, so that the number of components of the door is increased and thereby the assembly cost for all components is large.

It is an object of the present invention to provide a door for a household appliance and such a household appliance, in which the storage of door panels is improved.

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

A door according to the invention for a household appliance comprises a first door pane and a second door pane spaced therefrom. The door further comprises a panel which is arranged as at least partially covering edges of the door panes. In the aperture a storage device for storing the door glass is integrated with each other. Such a configuration therefore makes the panel multifunctional and achieves a component reduction with regard to the number of components of the door. Due to the integrated design and thus in particular one-piece

Forming the aperture with the storage device may also be undesirable

Position tolerances between the diaphragm and the storage device can be prevented. In addition, an undesirable positional tolerance between the storage device and the door panes can be prevented, as is achieved by the arrangement of the panel on the door panes and the associated positional security and the positional security of the storage device to the door panes. It is preferably provided that the storage device in a

Interspace between the door panes extends. The reliable storage of door panes to each other is achieved and the positioning of the

Storage device is designed with at least partial components so that a anyway existing space is used for the positioning of the storage device. An unwanted enlargement by another positioning of the

Storage device is prevented.

It is preferably provided that the storage device has an at least in

Connecting direction of the door windows rigid first storage unit and one of them deformable second storage unit. This is a very special one

Emphasized embodiment, since a dual functionality is achieved by this flexibility of the storage device. By the rigid storage device is achieved in this context that door glasses are kept at a certain distance and thus at a certain distance from each other, which can not be exceeded. On the other hand, is achieved by the deformable second storage unit sure that no unwanted moving and lifting the door glass of the entire

Storage device occurs and thus no unwanted noise and no unwanted strong force effects on the components mentioned occur, so that no damage or destruction especially a door glass occur.

Due to the deformable second storage unit is also at a specific

Relative movement of the door panels to each other or a door glass to the

Storage device achieved that the mechanical contact between a door glass and the second storage unit is always given. By the deformability and thus reversible elasticity of the second storage unit also movements of the

Door panel can be performed by this second storage unit, this permanent and permanent contact between a door glass and the second storage unit can be ensured. An undesirable noise due to the above scenarios is prevented. In particular, it is also achieved by this second storage device and its deformability that even if a door glass moves and optionally mechanically easily detached from the first rigid storage unit, at a then again below

occurring contacting quasi no unopposed contact takes place, but by the second storage unit a certain damping is generated and a very gentle contacting the door glass is achieved with the first rigid storage unit. Also Here, therefore, unwanted noise can be prevented and excessive mechanical contact with the first rigid storage unit can be prevented.

It is particularly advantageous in this context that the deformable second

Storage unit in the undeformed ground state is wider than the rigid first

Storage unit. Especially this configuration allows to ensure the above advantages in a special way.

Preferably, it is provided that the rigid first storage unit in a

Horizontal section H-shaped. Such a construction is mechanically very stable and torsionally stiff and allows the symmetrical design and a very uniform storage of two adjacent door windows. In addition, such an H-shape forms quasi four contact points with the respective opposite door panes, so that in this respect a multipoint bearing can be achieved. Here, too, undesirable tilting or the like of the door panes relative to one another and relative to the storage device can thus be avoided.

It is preferably provided that the deformable second bearing unit is formed in a horizontal section at least partially C-shaped. This is a particularly advantageous shape in this deformable storage unit, since by this thus the required reversible elasticity appears particularly well,

On the other hand, in comparison to pointed or punctual ends, in contrast to the C-shape, the largest possible contact surfaces with the door panes are formed. Especially with a relative movement between this storage unit and a

Door panel thus occur no unwanted damage to the door glass, for example, by pointed acting parts of the storage unit, which then a

Scratching the door glass would cause it to open.

It is preferably provided that in each case a C-shape of a deformable second bearing unit is arranged on both sides of the H-shape of the rigid first bearing unit, so that here also a symmetrical configuration in the

Cross-sectional view is formed in a horizontal section. The above advantages can hereby be further promoted. It is preferably provided that the two storage units are integrally formed, so that here too a component minimization is achieved and on the other hand

unwanted position tolerances between a separate first storage unit and a second storage unit are avoided. It is preferably provided that the deformable second bearing unit comprises in a vertical section two clip-like elastic straps which have curved end pieces facing each other in a space between the door panels. Such an alternative embodiment makes it possible to confirm the above-mentioned advantages in an analogous manner.

It is preferably provided that the aperture with the storage device

Plastic is formed. Thereby, it can be realized as a simple injection molded part, which is also formed relatively inexpensive and relatively light weight.

It is preferably provided that the panel is a top panel and / or extends over the entire length of the edges of the door panels. The design as a top panel thus represents an upper cover of the door panes and thus the upper horizontal edges of the door panes.

Furthermore, the invention relates to a household appliance for preparing food, in particular a cooking appliance, with a door according to the invention and an advantageous embodiment thereof. Embodiments of the invention are described below with reference to schematic

Drawings explained in more detail. Show it:

Fig. 7 is a partial view of the embodiment in Fig. 6 in a

Vertical sectional view.

In the figures, the same or functionally identical elements with the same

Provided with reference numerals.

In Fig. 1 a trained as a baking oven 1 household appliance for preparing food is shown in a front view. The oven 1 comprises a cooking chamber 2 which is closed by a door 3. The door 3 has a handle 4 on the outside. In addition, the oven 1 comprises an operating device 5, shown only by way of example in position and configuration, which by way of example has a display unit 6 and operating elements 7 and 8, the example also being referred to in terms of position and number. In Fig. 2, the door 3 is shown in a perspective view. It has a first door panel 9, which represents the door outer pane. The first door panel 9 is designed as a flat plate and, for example, made of glass. In addition, the door 3 comprises a second pane 10, which is formed as a door inner pane and is also designed as a flat plate, for example made of glass. It is spaced and parallel to the first

Door glass 9 is arranged. When the door 3 is closed, the door inner pane 10 is the door pane closest to the cooking chamber 2. The door panes 9 and 10 are arranged so that a gap is formed, wherein in this intermediate space as shown in Fig. 4 in the embodiment, further door panes 1 1 and 12 are arranged as door intermediate panes. They are also formed as plate-like elements, in particular made of glass and also spaced from each other and spaced from the door panels 9 and 10 are arranged.

The door panels 9 to 12 are held by door profiles 13 and 14 (Figure 2), with the door profiles 13 and 14 being elongated components disposed on an inner side 15 (Figure 4) of the first door panel 9, for example glued. In addition, the door 3 comprises a in Fig. 3 perspective shown top panel 16, which may be formed in the embodiment of plastic. The top panel 16 extends over the entire width (y-direction) of the door panels 9 to 12 and covers the upper edges 9a, 10a, 11a and 12a of the door panels 9 to 12 from above. The top panel 16 is also attached to the door profiles 13 and 14, for example via latching elements 17 and 18, which engage in latching receptacles 19 and a not visible in the Fig. Analog further locking receptacle of the door profile 14.

The top panel 16 further includes a plurality of slots 20 through which an air flow can occur.

At the top panel 16 beyond a not visible in Fig. 3, but indicated by the reference numeral 21 storage device is integrated and thus arranged in one piece. In Fig. 5 is a horizontal sectional view and thus in a

Sectional view in the y-z plane a first embodiment of the

Storage device 21 shown. Preferably, it is provided that 16 two storage devices 21 are formed adjacent to the ends of the elongated top panel. In Fig. 5, only one arranged on the top panel 16 storage device 21 is shown in this context. A bearing device 21 may for example be arranged between the disc 9 and the disc 1 1 or between the disc 1 1 and the disc 12 or between the disc 12 and the disc 10, wherein it extends to each case in the intermediate space. In the embodiment of FIG. 5 is shown by way of example, as a storage device 21 in a

Gap 22 between the disc 1 1 and the disc 12 extends. The Storage device 21 comprises as part 23 a first storage unit 24, which is rigid. This means that it is at least in a connecting direction (z-direction) between the door glass 1 1 and 12 rigid and thus formed undeformable. In the horizontal section illustration, the first storage unit has an H-shape. To the side following the H-shape is in each case a deformable second

Storage unit 25 integrally formed. The second elastic deformable

Units are in this connection direction between the door windows 1 1 and 12 and thus elastically and reversibly deformable in the z direction. In the

Horizontal section illustration, the storage units 25 a C-shape.

As can be seen and indicated in FIG. 5 (dashed representation), the width b1 of the second storage units 25 and thus the extension in the z-direction in an undeformed ground state is greater than a width b2 of the first storage unit 24. Then, the storage device 21 introduced into the gap 22 and brought the discs 1 1 and 12 in the assembled final state, the width b1 is reduced because the legs of the C-shape are compressed in the z-direction, in particular so far until the door panes 1 1 and 12th have contacted the ends of the legs of the H-shape of the first loading unit 24. If the door panes 1 1 and 12, for example, during the movement of the door 3 when opening or closing, move minimally in the z direction, then a short-term and distance-specific minimum release of a door pane 1 1 or 12 from the first

Storage unit 24 done. Due to the deformation of the bearing unit 25 with mounted door panels 1 1 and 12 and thus in the prestressed state of the second storage units 25 is in such a scenario, a spreading of the

Storage units 25 allows and a permanent and lasting contact between the storage units 25 and the door panes 1 1 and 12 is also achieved.

In Fig. 6 is another in a further horizontal sectional view another

Embodiment of a door 3 with a specific storage device 21 shown. This storage device 21 again comprises the first storage unit 24, which is rigid in the z-direction. In addition, the storage device 21 in particular comprises a single second storage unit 25, which in turn is in the z-direction is formed deformable. Here, too, the widths b1 and b2 are shown analogously to the illustration in FIG. 5, the representation here again being indicated in accordance with FIG. 5 of the undeformed ground state with its maximum width b1. The dashed representation represents both in Fig. 5 and in Fig. 6 with respect to the second

Bearing units 25 the undeformed prestressed state between the

Door panels 1 1 and 12, so that the outer sides of the C-shape in Fig. 5 and the outer sides of the bow-like configuration in Fig. 6 bear against the respectively facing surfaces of the door panels 1 1 and 12 contacting.

In this context, FIG. 7 shows a vertical sectional view in the xz-plane along the section line VI-VII in FIG. 6, wherein, in comparison with FIG. 7, also the one protruding out of the plane in FIG upwardly extending portion of the discs 1 1 and 12 and the top panel 16 with the

Storage device 21 is shown. As can be seen in the vertical sectional view in Fig. 7, this deformable second bearing unit 25 comprises two clip-like elastic brackets 26 and 27, which are bent so that their free ends 26a and 27a facing away from the respective contacting door panes 1 1 and 12 and on the other hand, these end pieces 26a and 27a extend oriented towards each other. Here too, for clarity, this maximum width b1 shown in the unclamped ground state is drawn, which is then greater than in the tensioned state between the door panes 1 1 and 12, which is also indicated in FIG. 7.

With the invention, a secure and reliable storage of door panels of a door of a household appliance is achieved, in particular intermediate disks of a disk package of a door can be stored reliably and safely. This can

be done to the effect that no unwanted noise with possibly occurring relative movements between the door glass on the one hand and the

On the other hand storage facilities occur when, for example, the door is moved. It can be achieved a secure multipoint bearing, being compensated by the positionally offset from one another embodiments of the two storage units, on the one hand the deformable, on the other hand, the rigid, component tolerances and

unwanted noise can be prevented. By the one with the deformable

Storage unit achievable positive locking with respect to the mechanical contact a door washer can be held in position even with sudden acceleration.
