Description

The present invention relates to a cooking appliance with at least one heatable cooking chamber with at least one wall and at least one cooking chamber opening for loading and unloading the cooking chamber. The cooking chamber is associated with at least one Gargutträgeraufnahme.

The Gargutträgeraufnahme represents an important feature of cooking appliances. The recording should allow a safe and stable positioning of the food support in the oven. In addition, the recording should be designed as compact as possible, so that the cooking space is not unnecessarily reduced and can be used as possible on the entire width or depth.

Another important feature of a Gargutträgeraufnahme is how expensive this is to be cleaned from occurring during operation contaminants. Therefore, it has proved to be particularly comfortable for the user to take pictures which are detachably fastened in the cooking chamber. This allows the recording very easy and convenient to be cleaned outside the cooking chamber.

In the prior art, various detachable Gargutträgeraufnahmen have become known. For example, there are systems that are screwed on each side of the cooking chamber with two or more knurled nuts. The disadvantage of this, however, is that the assembly or disassembly is often very complicated for the user, since the rear screw is very far in the cooking chamber. For the user, it is therefore often difficult to find the screw in the back of the cooking chamber and the knurled nut fitting on the thread and screw. Such Gargutträgeraufnahmen are therefore perceived by many users as uncomfortable.

Furthermore, Gargutträgeraufnahme have become known, which can be mounted without glands and, for example, have connectors. However, such recordings have the disadvantage that they often have no firm and play-free seat. In operation, therefore occur, for example, rattling noises. The user therefore often has the feeling that the receptacle is improperly mounted or possibly unsuitable for attachment in his cooking appliance.

It is therefore the object of the present invention to provide a cooking appliance with a detachable food support holder available, which can be easily and reliably mounted by a user.

The cooking appliance according to the invention comprises at least one heatable cooking chamber with at least one wall and at least one cooking chamber opening for loading and unloading the cooking chamber. The cooking appliance comprises at least one food product holder receptacle with at least one carrying device. The support means is arranged by means of at least one fastening means releasably in the cooking chamber. In this case, the fastening device comprises at least one abutment device. The abutment device has at least one abutment element arranged on the conversion abutment. The abutment device has at least one abutment receptacle arranged on the carrying device. The fastening device comprises at least one screwing device. By means of the screwing device, the carrying device can be screwed in the cooking chamber when the abutment receiving abuts against the abutment element with a bias voltage.

The cooking appliance according to the invention has many advantages. A significant advantage of the fastening device with at least one abutment device and at least one screwing. This allows a simple and stable installation of the support device. By biasing a tight fit without rattling noises can be guaranteed. Due to the prestressable abutment device can also be dispensed with poorly accessible screws and failure-prone and costly connectors. By the screwing can also be ensured that the preloaded abutment device is permanently fixed stable.

In all embodiments, it is preferred that the screwing device is arranged in a front half of the cooking chamber. Preferably, the screwing device is arranged closer to the cooking chamber opening than the abutment element. This allows a particularly good accessibility of the screw. The abutment element is preferably arranged in a rear half of the cooking chamber. It is also possible that the screwing device are arranged in an upper and / or lower half and the abutment element in a lower and / or upper half of the cooking chamber.

Preferably, the abutment receiving on the abutment element with a bias, which has a substantially parallel and in particular parallel to the operational direction of insertion for Gargutträger extending force direction. Under the direction of force is particularly understood the direction from which the support means must be pressed with the abutment receptacle against the abutment member disposed on the wall to apply the bias. Such a direction of force allows a particularly easy preloading, since the required force can be conveniently applied from the cooking chamber opening.

The abutment element is preferably permanently installed in cooking chamber. The abutment element is in particular intended to remain at a removal of the support means in the cooking chamber. For example, the abutment element is installed on the wall and / or an underlying component and z. B. bolted, riveted, welded, pressed and / or glued. Other suitable compounds are possible. It is also possible that the abutment element is formed integrally with the wall, for example by an embossment in the wall. A permanently installed abutment element is particularly comfortable for the user, since this does not have to worry about the abutment element during installation or uninstallation of the support device. It is also particularly advantageous that the abutment element projects beyond the wall into the cooking chamber. As a result, it can be found and reached particularly well by the user during assembly of the carrying device if he wishes to apply the abutment receptacle. The abutment receptacle is preferably permanently installed on the support device. Thus, the user only needs to hold the support means to bias it against the abutment member.

It is preferred that in the mounted state of the support means, the abutment member and the abutment receptacle along mutually curved coupling portions together. In this case, complementary curvatures are to be understood as meaning, in particular, complementary curvatures, such as, for example, an inward curvature and an outward curvature. Curved coupling sections have the advantage that initially a coarse alignment is sufficient and the support device is finally correctly aligned during pretensioning. An elaborate and complicated exact alignment, such as with connectors, is not necessary. In addition, it is particularly easy in such coupling sections to apply the support means to the abutment element, since an engagement of such coupling portions can be experienced haptic.

Particularly preferably, the coupling sections are rounded and, for example, convex and concave. Also possible are other, matched and in particular complementary curvatures of the coupling sections. Preferably, the abutment member and the abutment receptacle each have a coupling portion. Also possible in each case two or three or more coupling sections. It is preferred that the coupling portion of the abutment member protrudes into the cooking chamber with respect to the plane of the wall.

In a particularly preferred embodiment, it is provided that in the assembled state of the carrying device, the coupling sections and the screwing are arranged at a substantially same height and in particular at a same height in the cooking chamber. This effectively prevents tilting during toughening and screwing. In addition, this allows the bias remain particularly well maintained by the screwing. A further advantage is that a stable hold can already be achieved with a pair of coupling sections and a screwing device. For example, only an abutment receptacle and on the wall only one abutment element is provided on the support means. As a result, the user must attach only to an abutment element when inserting the support means, whereby the assembly is particularly uncomplicated. By the opposite screw a permanent and stable attachment of the support device is then achieved.

The abutment element preferably comprises at least one cylindrical shaft portion on which the coupling portion is formed. Particularly preferably, the abutment element is designed as a molded part or rotary part. Such an abutment element enables a particularly cost-effective and at the same time stable design of the fastening device. It is possible that the shank portion comprises at least one thread for mounting, for example, for screwing to the wall or another device part. The longitudinal axis of the cylindrical shaft portion extends in particular transversely to the direction of the force of the bias. As a result, the abutment receptacle can be supported particularly well on the cylindrical shaft portion. In addition, the cylindrical shaft section can then provide a correspondingly rounded coupling section particularly well.

It is preferred that the abutment receptacle has at least one concavely curved coupling section. The coupling section is suitable and designed to at least partially surround the cylindrical shaft section of the abutment element. Such a concavely curved coupling section can be produced particularly inexpensively, for example by a correspondingly bent wire. Preferably, the coupling portion of the abutment receptacle surrounds the cylindrical shaft portion of the abutment element of a Garraumöffnung facing side. Thus, the support device rests securely on the abutment element and the coupling sections can be coupled by inserting the carrying device from the cooking chamber opening.

It is further preferred that the abutment element has at least one securing portion. The securing portion is particularly suitable and designed to secure the coupling portion of the abutment receptacle against lateral displacement in at least one direction positively and / or non-positively.

The securing section is formed, in particular, on an end of the abutment element projecting into the cooking chamber.

The securing portion preferably has an enlarged cross-section with respect to the cylindrical shaft portion. For example, the securing portion is formed as a round and / or mushroom-shaped head. An abutment element with such a securing portion can be produced particularly inexpensively, for example as a molded part or turned part. Particularly preferably, the securing portion is cylindrical. In this case, the cylindrical securing portion has a larger diameter than the cylindrical shaft portion.

It is possible and preferred that the carrying device comprises a plurality of support element for pushing on food supports. The support elements are preferably attached to at least one cross member. The abutment receptacle is attached in particular to the cross member and / or on at least one of the support elements. This allows a particularly stable attachment of the abutment support, so that it remains permanently stable even with frequent disassembly of the support grid and a stronger bias.

The support elements in particular run parallel to the operational direction of insertion. In an operating position of the cooking appliance, the support elements in particular run horizontally. The support elements in particular run parallel to each other. The cross members in particular run transversely and preferably at right angles to the support elements. In an operational installation position of the cooking appliance, the cross member in particular run vertically. Particularly preferably, the support elements are attached to their end portions on the cross members, so that there is a support grid. In each case at least one cross member is preferably provided in a front and a rear region of the support grid. Particularly preferably, the support elements and / or the cross member are formed as wire rods.

In a further advantageous embodiment it is provided that the abutment receptacle is formed as a wire bow having a substantially U-shaped and in particular U-shaped bent coupling portion. Such a coupling section is particularly stable and can be very easily create a cylindrical coupling section. In addition, such a wire hanger can be produced inexpensively and reliably attached to the support grid. It is also possible that the abutment receptacle comprises at least one wire bow with such a coupling portion. Particularly preferably, the U-shaped bent coupling section is adapted to the cylindrical coupling portion of the abutment element.

The U-shaped bent coupling portion is preferably positioned centrally on the wire hanger. Preferably, the wire hanger is mounted centrally on the support grid. As a result, handling the support grid during assembly is particularly easy. Tilting when preloading and screwing is effectively prevented. But it is also possible an off-center arrangement of the coupling section on the wire hanger and / or an out-of-center arrangement of the wire hanger on the support grid. Particularly preferably, the U-shaped bent coupling portion is open in the direction of force of the bias. Contrary to the direction of force, the U-shaped bent coupling section is preferably closed. It is possible that the legs of the U-shaped coupling section converge at least in sections. It is also possible that the wire hanger serves as a cross member for one or more support elements. It is also possible that the wire hanger serves as a stop for food support, so that they can be inserted only to the wire hanger in the support grid.

It is possible that the wire bracket is secured with its end portions on at least one cross member. It is also possible that the wire hanger is fastened with its end portions on at least one of the support elements. Particularly preferably, the wire hanger is attached to a rear cross member. In particular, the end portions of the wire hanger are folded so that their longitudinal axis is transverse to the longitudinal axis of the wire hanger. Thus, the wire bracket can be attached particularly easily spaced to the cross member, for example by welding.

The wire bow is preferably bent at the end portions in a direction which is transverse to the bending direction of the U-shaped in the coupling portion. It is also possible that the wire hanger has at least one spacer to a wall and in particular to the side wall of the cooking chamber. Such a wire hanger with spacer has the advantage that the user finds particularly easy the correct distance to the cooking chamber wall when inserting the support grid.

In all embodiments, it is preferred that the screwing at least a screw, which extends in the assembled state by at least one attached to the support means holding member. The holding element is formed for example as a holding plate. Such a screw means provides a stable and cost-effective screwing the support means to the wall.
