Description

The invention relates to a device for receiving a food support for a domestic appliance, with a pull-out device which has a fixed attachable to the household appliance first rail, and at least one movable relative to the first rail second rail, on which the food support in the extension direction of the second rail relative slidably positionable to the second rail. Furthermore, the invention relates to a domestic appliance for preparing food, in particular an oven, with such a device. In addition, the invention comprises a method for operating such a device for receiving a food support for a domestic appliance.

Pull-out systems for ovens are known in many ways. In this context, telescopic rail devices are known which comprises a stationary pull-out rail and at least one relatively movable extension rail.

For example, such a device is from the DE 36 28 763 C2 known. In the local device, a integrally formed latching portion in the form of a dovetail is formed at a front end of a sliding pull-out rail. This engages in a compatible latching on the food support. This is the case when the food support is pulled completely forward in its pull-out end position. In the pushed-together end position, the front end of the pull-out rail is flush with the front edge of the food support.

Furthermore, from the DE 10 2004 031 724 A1 a pull-out system for household appliances known, especially for Gargutgeräte on which a food support is positionable. On a rail, a receptacle is formed, which holes at the top which serve as support points for the food support and which protrude through holes in the food support, so that the relative mobility between the food support and the receptacle is prevented in the assembled state.

Similarly, such a system is from the US 2006/0065265 A1 shown, in which case a hook-shaped engagement possibility for engaging in a food support is additionally formed at a front end of a drawer rail. Here too, in the assembled state, this hook is even projecting forward with respect to the food support.

In the known systems, the gripping of the food support is difficult for a user due to the position of the drawer rail to Gargutträger in the fully collapsed state. In other words, in the extended state, it first grips the baking tray and the extension bar at the same time and then has to carefully lift off the baking tray. Due to the temperature of the baking sheet, this is user-unfriendly. Likewise, this can be critical for the user with hot or liquid coating in the baking tray. In addition, in conventional over extension rails relatively high costs are available and there is a relatively large heatable mass available, whereby in this respect the energy balance of the domestic appliance is deteriorated.

It is an object of the present invention to provide a device for receiving the food support for a domestic appliance, a domestic appliance for preparing food with such a device and a method for operating such a device, in which the user friendliness with respect to the removal of the food support improved is.

This object is achieved by a device having the features of claim 1, a domestic appliance having the features of claim 12, and a method comprising the features of claim 13.

A device according to the invention for receiving a food support for a domestic appliance comprises a pull-out device which has a first rail which can be attached to the household appliance in a stationary manner. In addition, the extraction device comprises at least one movable relative to the first rail second rail, on which the food support in the extension direction of the second rail is relatively displaceable positionable to the second rail. In the pushed-together end position between the second rail and the food support the food support is positioned so that it is arranged in the longitudinal direction of the second rail with a projection over the front end of the second rail. By such a specific positioning between the food support and the second rail in the fully inserted end position, the user-friendliness can be increased since the gripping of the food support is substantially improved. It is no longer necessary to grasp the food support together with the rail in order to be able to bring it out. In addition to the improved and more targeted handling thus the risk of injury due to a cumbersome and not fixed gripping the food support can be prevented alone. In addition, a very ergonomic and intuitive grip option of the food support alone can be created by this specific positioning. This specific position design between the food support and the front end of the second rail in the fully collapsed state virtually frontal and lateral clearance is created that allows easy and safe gripping the food support alone to move the food support. Just when, when further extending the food support a position is reached, in which only the food support can be moved relative to this second rail and this is also wanted, this is now fully and easily possible, without embrace a user or in cumbersome and unnatural fingering the second rail must then let go.

Preferably, a grip area is formed on the food support in the region of the supernatant, so that even easier and less expensive and safer grip option of the food support is guaranteed here alone.

Preferably, the supernatant is larger or the like 2cm, in particular between 2cm and 5cm. Especially these dimensions are on the one hand particularly advantageous to ranzubringen finger or the like easily and without abutting on the rail and beyond but not so oversized dimensioned that unnecessary space would be required in the longitudinal direction of the extension device. Preferably, a front stop for the food support is formed at the front end of the second rail and in the collapsed end position between the second rail and the food support is the food support in the longitudinal direction of the second rail considered with the supernatant on the front stop of the second rail. In particular, the front stop is a cap, which is attached to the second rail. The cap is thus preferably a separate part, which is also optionally detachable from the rail again. Especially with wear or other required replacement, so only the cap can be removed alone and replaced by a new one. In addition, such a design of the cap can be formed of a suitable material, on the one hand to keep the wear low, and to keep the temperature transfer from a heated food support to the rail on this thermal bridge as low as possible. Preferably, the cap is made of a plastic, in particular a weak or non-thermally conductive plastic. In this regard, thus at least some of the contact points between the rail and a part thereof and the food support can be made weak heat-conducting or non-heat-conducting, so that in this respect a strong heating over this contact point can be avoided.

Preferably, a standard pull-out rail, which is referred to as a so-called normal pull-out rail, is used as the second rail. In this regard, a more cost-effective design compared to previously used in excess extensions drawer rails can be accomplished in which the second rail is a specially trained Überauszugsschiene.

Preferably, starting from the pushed-together end position of the two rails and the pushed together end position between the food support and the second rail of the food support to pull on a handle area in the region of the supernatant before the front end of the second rail palpable. In addition, in this collapsed end position, the projecting arrangement of the food support is also designed so that a user can grab the food support in this supernatant also laterally and not only front, especially in the grip area, without which he would have to take the second rail. Just this side handle is in terms of natural movement and intuitive Procedure with the user particularly advantageous, so that he automatically picks up here only due to the supernatant even with a lateral gripping the food support.

Preferably, an end stop for the food support is formed on the second rail, to which the food support is struck in the pushed together with the second rail end position. In particular, the end stop is formed on the upper side of the second rail pin, to which a rear edge of an edge flange of the food support is struck in the end position. Preferably, the distance between this pin and in particular the front of the cap on the second rail is smaller than the length of the food support. By this specific positioning and length design, the supernatant of the food support, in particular by the above-mentioned specific length values, is automatically reached in the pushed-together final state. An independent adjustment of the user to achieve this specific supernatant are therefore not required because they are then reached automatically due to the end stop.

Preferably, it is provided that, starting from the pushed-together end position of the at least two rails and the pushed together end position between the food support and the second rail, a first Teilauszugweg is formed in which the food support and the second rail are stable in position to each other. In this Teilauszugsweg the food support and the second rail are also moved relative to the first rail. In particular, the first Teilauszugsweg is between 60% and 80%, in particular 70% of Gesamtauszugswegs between the rails and the food support.

Preferably, starting from the collapsed end position of the rails and the collapsed end position between the food support and the second rail on the Auszugweg after the first Teilauszugsweg a second Teilauszugsweg is formed in which the food support and the second rail are relatively movable, and in particular the second Teilauszugsweg then begins when the second rail has reached its maximum extension length from the first rail.

Preferably, a pull-out stop element, in particular a stamping on a lateral edge flange, is formed on the food support, which in the pull-out end position is in contact with the front stop of the second rail. In addition, the device preferably has a tilt protection element for preventing tilting of the food support in the extension end position on the lateral edge flange, in particular this grip protection element is formed behind the extension stop element.

Furthermore, the invention relates to a domestic appliance for preparing food, in particular an oven, with a device according to the invention or an advantageous embodiment thereof. The extraction device of the device is arranged on side walls of a muffle in the cooking chamber of the household appliance.

Furthermore, the invention relates to a method for operating a device for receiving a food support for a domestic appliance, with a pull-out device which has a stationary attached to the household appliance first rail, and at least one movable relative to the first rail second rail, on which the food support in the extension direction of the second rail is relatively displaceable positionable to the second rail. In the pushed-together end position between the second rail and the food support, the food support, viewed in the longitudinal direction of the second rail, is positioned projecting beyond the front end of the second rail with a projection.

Preferably, a cap is formed as a front stop for the food support at the front end of the second rail and in the pushed together end position between the second rail and the food support of the food support in the longitudinal direction of the second rail considered with the supernatant over the front stop of the second rail protruding positioned.

Starting from the pushed together end position of the rails and the collapsed position between the food support and the second rail, the food support is laterally gripped for removal from a grip area in the region of the projection in front of the front end and / or in the region of the projection. This is done in particular because of the supernatant advantageous in that only the food support and not the second rail and also not the first rail to be gripped.

Preferably, starting from the collapsed end position of the rails and the collapsed end position between the food support and the second rail, a first Teilauszugsweg formed in which the food support and the second rail are moved stable position to each other and moved together relative to the first rail, and in particular the first Teilauszugsweg between 60% and 80%, in particular 70%, of Gesamtauszugswegs between the rails and the food support is. Preferably, starting from the pushed-together end position between the food support and the second rail on the Auszugweg after the first Teilauszugsweg a second Teilauszugsweg is formed, in which the food support and the second rail are moved relative to each other. In particular, the second Teilauszugsweg begins when the maximum extension length between the first and the second rail is achieved.

By cap preferably several functions are taken over, which serves as a front boundary of the second rail, and serves as a stop for the food support and serves as an insertion aid for the food support. The rear end stop also serves as a positioning aid for the Gargurtträger.

In particular, the food support is deposited on the cap during operation and pushed to the rear end stop, in which case the front end of the food support in the end position is not on the rail, since the supernatant is formed.

Further features of the invention will become apparent from the claims, the figures and the description of the figures. The features and feature combinations mentioned above in the description as well as the features and feature combinations mentioned below in the description of the figures and / or in the figures alone can be used not only in the respectively specified combination but also in other combinations or in isolation, without the scope of To leave invention.

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

In Fig. 1 is a perspective view of an extension device 1 shown from above. The device 1 comprises a pull-out device 2 which has a first rail arrangement 3 and a second rail arrangement 4. The two rail assemblies 3 and 4 are in particular attached to opposite side walls of a muffle of a baking oven. The rail assemblies 3 and 4 are arranged on the same level and define a shelf level in the cooking chamber of the oven.

In the exemplary embodiment, each of the rail assemblies 3 and 4 comprises a first rail 5 fixedly arranged on the muffle inner wall (marking the rails only for the rail arrangement 4) and a second rail 6 movable relative thereto. The design and mode of operation of the rail arrangement 3 is analogous to FIG Rail arrangement 4, so that in the following the explanation is made only for the rail assembly 4.

In addition, a food support 7 is provided, which may be a baking sheet or a grid or the like. The food support 7 has a receiving area 8, in which food can be consumed or released during the preparation of food media such as fat or the like can be collected.

The food support 7 is formed like a trough and has circumferentially edge flange 9, 10, 11 and 12.

The food support 7 is positioned in the illustration shown on the rail assemblies 3 and 4, in particular the second rails 6. The second rails 6 has at their front ends 12 a cover caps 13a and 13b, which serve as a front stop for the food support 7 in the fully extended state.

The second rail 6 is movable relative to the first rail 5. The food support 7 is also movable relative to the second rail 6 along a pull-out path within a second partial pull-out path.

The device 1 also includes anti-tip elements 14 and 15, which serve to prevent tilting of the food support 7 in the fully extended state. The anti-tip elements 14 and 15 are formed as lateral engagements about the edge flanges 10 and 11 encompassing.

In addition, 10 and 12 Auszugstoppelemente 16 and 17 are formed on the edge flanges, which are in particular embossments in the material of the edge flanges 10 and 12. As can be seen, the pull-out stop elements 16 and 17 are formed in the longitudinal direction of the second rail 6 and thus in the x direction in front of the anti-tip elements 14 and 15.

In addition, on end faces 18 of the second rails 6 end stops 19 a and 19 b are formed, which are designed as pins.

In the in Fig. 1 shown fully collapsed end position, a rear edge 20 of the rear edge flange 11 at these end stops 19 a and 19 b struck.

The end stops 19a and 19b contact only the rear edge 20, but do not engage in possible openings in the form of holes in the food support in order to keep this positionally fixed relative to the second rail 6.

In the in Fig. 1 to 3 shown fully pushed together end position between the two rails 5 and 6 on the one hand and between the food support 7 and the second rails 6 on the other hand, a supernatant d ( Fig. 2 ) educated. This means that in this state the food support 7 protrudes beyond the cover cap 13 forward in the x-direction to this supernatant d. The supernatant d is preferably between 2cm and 5cm. By such a configuration, the user-friendly possibility is created that in this fully collapsed state a user can reach into a handle portion 21 of the food support 7, without he would have to embrace the rail assemblies 3 and 4, in particular the second rails 6, if he the food support. 7 Front side attacks.

The cover cap 13a or 13b is preferably a separate part from the second rail 6, which is attached to the front end 12.

The second rail 6 is a standard pull-out rail or a standard pull-out rail.

In Fig. 3 FIG. 12 is a bottom view of the device 1 shown in its fully collapsed end position condition. FIG.

In Fig. 4 is an oblique perspective view from above of the device 1 in a fully extended state shown. This means that the two rails 5 and 6 are positioned in their maximum extension length relative to each other and beyond the food support 7 is positioned in its maximum extension length relative to the second rail 6. In this fully extended state of the device 1, the cover 13a or 13b is struck on the pull-out stop element 16 and 17. In addition, the anti-tilt elements 14 and 15 prevent unwanted tilting of the food support 7 from the second rails 6.

Starting from the fully collapsed end position of the device 1 according to the Fig. 1 to 3 is via a first Teilauszugsweg, which preferably 70% of in Fig. 4 shown Vollauszugsweg starting from the fully collapsed final state in the Fig. 1 to 3 is provided. In this first Teilauszugsweg the user engages quasi in the grip area 21 and thus engages only the food support 7, in which case a relative movement of the food support 7 and the second rail 6 to the first rail 5 takes place. The food support 7 and the second rail 6 do not move relative to each other in this first Teilauszugsweg. Subsequent to the first Teilauszugsweg then a second Teilauszugsweg is formed, which affects the remaining in particular 30% of the total extension travel. In this no relative movement between the two rails 5 and 6 is then given more and the food support 7 is moved only relative to the second rail 6. The first Teilauszugsweg extends over the length 11 wherein the second Teilauszugsweg extends over the length 12, as in Fig. 5 is shown.
