Description

The invention relates to a device for holding a food support in a cooking chamber of a cooking appliance, as well as a cooking appliance with such a device.

In ovens it is known that in the oven support frames are introduced, which serve to hold food supports, such as a grill pan, a baking sheet or a grid. Usually, these support frames are arranged on the vertical side walls of the muffle, which limits the cooking chamber. They can be designed as removable components, for example as a lattice girder. However, it can also be provided that devices are formed integrally in the muffle walls. The always pairwise oppositely designed insertion guides such devices then turn turn Einschubbenen for a food support.

From the prior art, as shown in FIG Fig. 1 a corresponding device 1 is known, which has two analogous to each other formed supporting frames 2 and 3. These can be arranged on opposite side walls of a muffle, which is not shown. The support frame 2 is constructed of rods and comprises two vertical support rods 4 and 5, on which a plurality of guide rods is always formed in pairs. For example, the two guide rods 6 and 7, which extend parallel to each other, form an insertion guide 8 for the exemplary food support 9 in the form of a grid. As from the illustration in Fig. 1 can be seen, the two guide rods 6 and 7, as well as all other guide rods of the support frames 2 and 3 are formed exclusively extending in a horizontal plane.

If the grid is as shown in Fig. 2 pulled out and there is then another object 10 on the food support 9, then forms due to the resulting weight under the leverage of the front projecting Gargutträgers 9 a force on the trained in the illustration shown guide rods 6 and 7th

The guide rods 6 and 7 are U-shaped in a horizontal plane and connected on both sides with the support rods 2 and 3. The legs of the U-shape and thus the shell sides of the guide rods 6 and 7 are welded to the shell sides of the support rods 2 and 3 fitting, and thus cross-welded.

Another support frame is from the DE 10 2006 015 444 B4 in which an upper guide rod is formally unequal to a lower guide rod of an insertion guide.

It is an object of the present invention to provide a device for holding a food support in a cooking chamber of a cooking appliance and such a cooking appliance with at least one device in which or in which the insertion of a food support can be made easier by an insertion guide formed by guide elements.

This object is achieved by a device and a cooking appliance according to the independent claims.

An inventive device for holding a food support in a cooking chamber of a cooking appliance comprises a carrier which has at least one insertion guide for receiving the food support. This insertion guide is limited by an upper and a lower guide element. An essential idea of the invention is to be seen in that the upper guide element has at one end a cross-sectional surface, which is oriented in particular perpendicular to the longitudinal axis of the guide element, which is arranged opening to a first support rod of the carrier and the guide element at this point of contact with the holding the first support rod is connected. As a result of this embodiment, the guide element opens onto the support rod, so that it extends at least at one end laterally of this support rod and is fastened thereto. On the one hand, this design saves space and a significant advantage is also to be seen in the fact that, when a food support is inserted into the insertion guide, the food support gets stuck in it Guide element is prevented with this end. The support bar covered in this embodiment thus considered in its extension at least over a certain length of the guide member of this guide element, so that in this rectilinear viewing direction and thus in extension of the support rod of this guide element at this considered end is not arranged projecting laterally before this support rod.

In addition, an improved attachment is made possible by such an end-side connection of the guide element to the support rod. This cross-sectional surface allows a larger-scale concern of the guide element on the support rod and thus also a more extensive non-destructive attachment. In addition, this front-side cross-sectional surface of the guide element can also be formed dented, so that it is adapted to the round shape of the support rod or its lateral surface, so that the full-surface concerns is further improved. In addition, such an embodiment also achieves an already mechanical mounting in a horizontal direction perpendicular to the support rod and perpendicular to the longitudinal axis of the guide element, which is then improved by the additional nondestructive permanent connection between the guide element and the support rod.

It is preferably provided that the cross-sectional surface is fastened by a welded connection to the first support rod. This non-destructive permanent connection is then also designed so that it does not additionally apply material to the side of the support rod and the advantages mentioned above are further promoted.

It is preferably provided that the cross-sectional surface opens to a second support bar of the carrier facing the inside of a lateral surface of the first support rod. Through this specification, the above-mentioned advantages are taken into account to a particular extent.

It is preferably provided that the upper guide element has a first element piece extending from the first end in a straight line and thus without bending or deflection-free in the direction of a second support rod. This embodiment is with respect to the aligned with the support rod assembly of the Guide element in this first section particularly advantageous. Especially at a front first end thereby threading a food support in the insertion guide is particularly user-friendly. Because it is just in this front first end and thus the side of the support rod no area of the guide member and not the first element piece extending arranged so that also in terms of the width of the food support according to between two devices or supporting frames extending and held on both sides Gargutträger not splayed on such laterally projecting upper guide elements in this front area or jammed. The handling by a user is thereby significantly improved.

It is preferably provided that at an end remote from the first end of the first element piece, an S-shaped bend is formed as a second element piece. By this design, a recess is created virtually in the front region of the upper guide element, which favors the insertion or threading of the food support in the insertion guide. By the S-shaped bend the targeted guidance of the inserted food support is then favors in a subsequent subsequent further length of the upper guide element and thus also the insertion guide. He is thus then held by the upper and lower guide member up and down and can then no longer be undesirably lifted or tilted in the context and tilted down and not fall out. As a result of this specific design of the upper guide element with these two concrete elementary elements explained in terms of form, an embossing or bulging of the upper guide element considered in a horizontal plane is arranged and formed backwards relative to the front end. A front-side insertion zone or threading zone formed thereby for the food support, through which it no longer has to be introduced exclusively in the horizontal direction into the insertion guide at the front end, is also enabled by this specific embodiment of the invention quasi a sinking from above. This quasi from above sinking the food support can then also take place at a point in which viewed in the depth direction of the cooking appliance, the food support already overlapped with the upper guide member and is located within the first element piece. It is preferably provided that the S-shaped bend extends in a horizontal plane. It preferably extends in one direction to an oppositely formed further device for holding a food support, which is preferably identical to the other device, these two devices are then arranged on opposite vertical walls of a cooking chamber of the cooking appliance limiting muffle.

This orientation of the S-shaped bend the insertion guide is not restricted in vertical dimensioning and thus in terms of the inside width in the vertical direction, so that here the displacement behavior of the food support is not affected relative to the insertion guide and smooth and smooth and thus user-friendly.

It is preferably provided that at a side facing away from the first element piece of the upper guide member end of the second element piece, a third element piece opens, which is connected to the second support rod. In this embodiment, the upper guide element thus formed by these three element pieces, which are each considered specifically shaped and represent in total the specific shape of the upper guide element.

In a preferred embodiment it is provided that the third element piece is L-shaped and is fastened with a shell side of a short leg of the L-shape on an inner side of the lateral surface of the second support rod, in particular welded thereto. In this embodiment, the preferably rear end of the upper guide element is then arranged and fixed in a cross-welded arrangement with the support rod.

In an alternative embodiment, it is provided that the third element piece on the upper guide element at a second end has a cross-sectional surface, which is arranged opening on the second support rod of the carrier, wherein the upper guide element is connected to this contact point holding the second support rod. In this embodiment, the rear end of the guide member is then connected in a corresponding manner to the rear second support rod, as the front end is connected to the first front support rod. In this embodiment then at the rear end at least over the third element piece aligned arrangement with the rear support bar achieved when looking in the depth direction of the cooking appliance, the depth direction orientation is taken perpendicular to the support bar aptly. The third element piece thus has at least one rectilinear subelement which represents a rectilinear end piece which opens onto this second support rod. Between this rectilinear end piece and the second element piece, an intermediate piece of the third element piece bent at least once can then also be arranged and formed, this intermediate piece then being a part of the third element piece.

It is preferably provided that the cross-sectional surface of the second end opens onto an inner side of a lateral surface of the second support rod facing the first support rod of the support, in particular with a welded connection attached thereto.

It is preferably provided that the lower guide element is formed in a horizontal plane U-shaped and is secured with lateral surfaces of side legs of the U-shape on mutually facing inner sides of the lateral surfaces of two support rods of the carrier. By such a configuration, the lower guide element is different in shape and thus formed asymmetrically to the upper guide element. It is achieved by this configuration, in particular in the front region, that the lower guide element already at its front end already extends laterally of the front support rod and thus the first support rod, so that the food support can be quasi already placed on this lower guide element, but by the Upper guide element in this front area is not covered and quasi out, so that the food support can be lifted from this lower guide element and can be taken upwards. Accordingly, the insertion can take place.

It is preferably provided that an upper and a lower guide element, which form an insertion guide, are arranged to extend between two support struts and are connected to the two support rods. The guide elements forming an insertion guide each extend in horizontal planes, the two horizontal planes of the guide elements being oriented parallel to one another. The Guide elements each extend completely in said horizontal planes.

In particular, the guide elements are rods. You can be very filigree and form-specific trained and yet have a high stability. As a result, the entire device is designed to minimize weight and the handling of a user for inserting and removing a food support is improved and circumferentially visible.

Preferably, it is provided that the carrier is designed as a support frame and is constructed of rods, in particular completely made up of rods, in which case the support rods and the guide elements designed as guide rods are mentioned.

Furthermore, the invention relates to a cooking appliance with a cooking chamber, wherein the cooking appliance has at least one device according to the invention or an advantageous embodiment thereof. In a particularly advantageous manner, it is provided that the cooking appliance has two separate devices with two carriers, which are arranged on side walls of a muffle and have pairwise opposite insertion guides, in which the food support is insertable and storable.

The carrier designed as a lattice girder or support frame is preferably formed from metal rods which, if appropriate, may be correspondingly coated. This is advantageous in terms of low wear when used in a cooking chamber, especially in a pyrolysis of the cooking appliance.

It can also be provided that the carrier is reversibly releasably attachable to a muffle wall which limits the cooking space, so that it can be used at any time and removed again. However, it can also be provided that the device and the muffle wall or the muffle walls are each formed integrally with the carriers and, for example, corresponding embossings are formed in the lateral vertical muffle walls.

Preferably, two devices are provided, which are arranged opposite to side walls of a muffle and pairwise opposite insertion guides have, in which the food support with opposite sub-areas can be inserted and stored.

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

In Fig. 3 is shown in a simplified perspective view of a baking oven 11 as a cooking appliance. This includes a cooking chamber 12, which by a in Fig. 3 not shown door is closed. The cooking chamber 12 is bounded by a muffle 13. The muffle 13 has two vertical side walls 14 and 15.

In the illustration according to Fig. 3 is simplified on the vertical side wall 15, a carrier in the form of a lattice girder or a support frame 2 'arranged. On the opposite vertical side wall 14 a correspondingly formed support frame is arranged.

In the exemplary embodiment, the support frame 2 ', which is part of a device 1' for holding a food support 9 ( Fig. 4 ) is reversible and thus non-destructively releasably attachable to the inside of the vertical side wall 15.

The support frame 2 'constructed in the exemplary embodiment from rods comprises the two support rods or support rods 4 and 5. In between, a plurality of rod-shaped guide elements extend in the horizontal direction (y-direction). In this case, by way of example, two rod-shaped guide elements 6 'and 7' form an insertion guide 8 '.

The arranged on the vertical side wall 14 further support frame of the device 1 'has an analogous configuration of guide elements, which are arranged in the vertical direction (z-direction) at the same height level.

In Fig. 4 is an embodiment of the support frame 2 'of the device 1' is shown in a perspective view. The support frame 2 ', which is constructed exclusively from rods, shows the front vertical linear first carrier bar 5 and the second carrier bar 4 spaced apart from and parallel to it.

The support rods 4 and 5 extend in the z-direction.

In pairs form upper and lower guide elements 7 'and 6' insertion guides 8 '. By way of example, here an insertion guide 8 'is provided with the reference numerals for the guide elements 6' and 7 '. The lower guide element 6 'extends with its U-shape in a horizontal plane and thus perpendicular to the z-direction in an x-y plane. In a spaced parallel horizontal plane also extends completely the upper guide member 7 '.

As from the illustration in Fig. 4 can be seen, the two guide elements 6 'and 7' are formed differently in shape and thus also provided with a certain asymmetry.

In this context, the upper guide element 7 'is not U-shaped, but has a first element piece 7a' on. This first element piece 7a 'is rectilinear and extends in particular only in the depth direction and thus in the y direction. The upper guide element 7 'embodied as a rod opens at a front end 71', which also forms the front first end of the first element piece 7a ', on an inner side 5b of a lateral surface 5a of the front first support rod 5. For this, in particular the cross-sectional surface 71a' (FIG. in particular surface in the xz plane and perpendicular to the longitudinal axis of the guide element 7 ') of the rod-shaped first element piece 7a' and thus of the end 71 'on this inner side 5b of the lateral surface 5a. In particular, a welded connection is formed here, so that thereby also the upper guide element 7 'is held at this contact point, which is formed by this cross-sectional surface 71a' and the surface of the inner side 5b at this point.

As well as in Fig. 4 can be seen, is directly adjacent to this rectilinear first element piece 7a 'at one of the front end 71' opposite the second end 73 'adjacent or subsequently a second element piece 7b', which is bent in an S-shape. The orientation of this S-shaped bend is such that it corresponds to a in Fig. 4 not shown further support frame, which is attached to the side wall 14, facing away from each other.

In addition, in this embodiment, the upper guide member 7 'comprises a third element piece 7c', which is L-shaped and opens directly to the second element piece 7b '. This third element piece 7c 'is then fastened, in particular welded, to an inner side 4b of a lateral surface 4a of the support rod 4 facing the support rod 5, so that here only the lateral surface of the support rod 4 and the lateral surface of the third element piece 7c 'contact and thus there is a cross weld here. The short leg also forms a rear end 72 'of the guide element 7'.

As a result of the asymmetrical and non-uniform design of the guide elements 6 'and 7' in the front region (viewed in the y direction), an insertion zone 16 for the food support 9 is created. Due to the specific shape and in particular by the specific arrangement and attachment of the first element piece 7a 'on the support rod 5 is when viewed in the y direction, the first element piece 7a' arranged in alignment with this support rod 5 and thus extends in the x-direction or in negative x direction not laterally of the support rod 5. As a result, the insertion and threading of the food support 9, in particular its side flanges, in the insertion guide 8 'much easier. Just the front end 71 'is thus no longer on the side over the support rod 5, so that a bumping or jamming or spreading of the food support 9 is prevented. Last but not least, an improved mechanical attachment is made possible by this end-side contacting of the first element piece 7a 'on the supporting rod 5 and can be designed over a large area.

By considered quasi in the depth direction and thus viewed in the y-direction formed by the S-shaped bend bulge or molding of the upper guide member 7 'backwards and thus offset from the front end 71' is formed rearwardly, the food support 9 easier be introduced into the insertion guide 8 '. It can already be sunk in from the top and placed on the lower guide rod 6 'and can then be selectively guided in further movement in the y direction between the two guide elements 6' and 7 'in the rear lengths. When introducing the Gargutträgers 9, this can thus be placed so quasi also from above on the lower guide rod 6 'and then in the horizontal direction to the rear be pushed, which is much more user-friendly for the operation and operation.

It is preferably provided that the S-shaped bend and thus the second element piece 7b 'not too far back offset with respect to the length of the upper guide member 7' is formed considered. Preferably, this second element piece 7b 'within a length interval, which measures between a front length fifth and a front Längendrittel the total length of the upper guide element 7' between the two support bars 4 and 5, formed, so that the food support 9 are still pulled out as far as possible can, without that he would tilt down, so that even then as far as the front positioned anti-tipper by the superimposed guide elements 6 'and 7' is formed.

In Fig. 5 is a perspective view of another embodiment of a support frame 2 'shown. This has, in contrast to the illustration according to Fig. 4 a different configuration of the rear third element piece 7c 'on. In this embodiment in Fig. 5 is this third element piece 7c 'is not L-shaped, but extends starting from the opening to the second element piece 7b' end initially rectilinearly backwards, to then have an S-shaped bend, opposite a rear end 72 'of the upper guide element 7 'forward and thus in the direction of the front end 71' is offset. A portion of this third element piece 7c ', which extends between the S-shaped bend and the rear end 72', is in turn formed rectilinearly and opens with a cross-sectional surface 72a 'to the inner side 4b of the lateral surface 4a. Here too, in particular, an alignment of this rectilinear section of the third element section 7c 'in the y-direction with the support bar 4 is designed and arranged. Preferably, the guide element 7 'in the embodiment in Fig. 5 formed in a shape symmetrical to a horizontal axis extending centrally between the ends 71 'and 72'.

In Fig. 6 a partial section of the cooking appliance or oven 11 is shown, in which the food support 9 in the region of the zones 16 of the opposite support frames 2 'and 3' is arranged and on the lower guide elements 6 'rests and in Subsequently, by a movement in the y direction in the insertion guides 8 'can be introduced.
