Description

The present invention relates to an oven with an oven muffle, on which at least one pull-out guide is arranged, each of which has a stationary guide rail and a movable running rail, with two side rails with at least one receptacle for a food support being held on the running rail, which is located between the two opposite ones Is arranged side rails, the side rails are formed in a direction parallel to the longitudinal direction of the pull-out guides shorter than the food support, the side rails comprise a plurality of horizontal bars, each forming receptacles for the food support.

There are ovens in which a food support is held in a movable manner on pull-out guides which are fixed in an oven muffle on opposite sides via side rails. Such food supports can be easily moved in front of the oven muffle, but the food support is only loosely lying and not secured against unintentional lifting. There is also the disadvantage that when the food support is removed, the rails of the pull-out guide protrude comparatively far in front of the oven muffle and pose a risk of injury.

In order to make the guidance of a food carrier safer, baking trolleys are known, on both sides or according to the DE 10 2005 019 956 A1 are arranged unilaterally. In such baking trolleys, a food carrier can be securely fixed to a receptacle, with the problem here too that when the food carrier is removed, the baking trolley protrudes comparatively far from the oven muffle and poses a risk of injury. With baking trolleys arranged on both sides, the food support can only be removed from the front, since the side rails extend over the entire length of the food support. If the baking trolley is arranged on one side, the food support must be lifted out of the holder from the other side. This requires a great deal of effort with heavily loaded food carriers. Also, when the baking trolley is arranged on two sides, the food to be cooked can only be checked from the front when the food support is fully extended, which means that the food can cool down again and the user is exposed to the hot air escaping from the oven.

DE 75 05 695 U discloses an oven with a muffle, the opening of which can be closed by a door. A baking and roasting tray is in on the side the muffle arranged and towards the inside of the door inclined extending guide rails and formed by profile carriers, which are placed on U-profile rails. Several wire brackets are arranged one above the other in the profile supports to accommodate slide-in parts. In the DE 25 08 005 A1 and DE 77 08 782 U1 a similar oven is disclosed in each case.

the DE 42 36 740 A1 discloses a baking oven with a muffle on which a swing-out articulated linkage for releasably receiving at least one cooking support is mounted in the ceiling area. The articulated linkage includes holders that are slidably mounted in the direction of the depth of the muffle.

DE 38 15 440 A1 discloses a telescopic slide-in device for accommodating food supports for baking ovens with several baking or roasting levels one above the other, which can be moved in and out of the baking chamber via rails mounted so as to be longitudinally displaceable and with roller guides.

DE 102 41 488 A1 discloses a cooking oven muffle for accommodating several interchangeable food carriers.

It is therefore the object of the present invention to create a baking oven which has improved handling when preparing food on a food support.

This object is achieved with an oven having the features of claim 1.

The baking oven according to the invention comprises a food support which is held on opposite sides on side rails which are mounted such that they can be moved via a pull-out guide. The side rails are shorter than the food support in a direction parallel to the longitudinal direction of the pull-out guides, so that when the food support is pulled out, the side rails protrude less from the oven muffle than the food support. As a result, when the food support is removed, the risk of components protruding from the oven muffle can be reduced and, at the same time, improved access to the food and the food support can be achieved. This makes it possible to ergonomically grip the food support on both sides and remove it without great effort. Also checking the food from the side, without contact with the outflowing hot air of the oven is possible through the oven according to the invention.

Preferably, the food support can be arranged in a middle pull-out position with a front section protruding on the oven muffle, while the two side grilles are still completely arranged in the oven muffle. In such a central extension position between the retracted position and the maximum extension position, the food support can protrude slightly from the oven muffle, so that the food on the food support can be checked during preparation or the food support can be removed from the side rails without the side rails protruding from the oven muffle and pose a risk of injury. After the food support has been removed, the side rail can remain in this position until at least one food support is picked up again and does not have to be touched when it is hot.

According to the invention, the food support is at least 20%, in particular at least 30%, longer in the longitudinal direction than the side rail. The side grille can have, for example, 20% to 80% of the length of the food support in the longitudinal direction.

In a further embodiment, latching means are provided which latch the side rail in a maximum extended position. The latching means can be provided on the pull-out guide, on the side rail or on another component. The latching means are preferably formed by resilient metal webs or other latching devices which have certain holding forces in order to prevent the side rail from accidentally moving into the latched position. Alternatively or additionally, the side rail can be locked in a central extended position, which is located between the retracted position and the maximum extended position. In the middle pull-out position, the side rail is preferably still arranged completely inside the oven muffle, and a front section of the food support protrudes from the oven muffle.

For stable guidance, the side rail can be arranged hanging on the pull-out guide on at least one side, preferably on both sides. In this case, the stationary guide rail can be arranged above a movable running rail of the pull-out guide. As a result, the pull-out guide is arranged in an upper area that is less accessible for children is. Alternatively, the running rail can also be arranged above the guide rail.

In order to be able to move the food support preferably completely in front of the oven muffle, the pull-out guides have a pull-out extending center rail between the stationary guide rail and the running rail.

The running rails and/or the side rails can also be connected to one another via synchronization means in order to ensure a uniform extension movement.

In order to secure the food support against tipping over, an edge of the food support can be arranged between two horizontal bars on at least one side rail. A projection projecting downwards on the upper bar can ensure that the food support is fixed in place so that it cannot tip over.

In a further embodiment, the running rail can be at least 10% shorter in the longitudinal direction than the guide rail. Then, when the food support has been removed, the side rails and also the running rails can remain arranged inside the baking oven muffle in a central pull-out position, so that a door of the baking oven can be closed.

According to the invention, the pull-out guide is shifted between a completely pushed-in state and a pulled-out state in which the front end of the running rail does not protrude beyond the front end of the guide rail.

As a result, the side rail is located inside the oven in both positions and the door can always be closed, even when the rail or side rail is in the front position, if no food support is attached. After removing the food rack, you don't have to touch the hot pull-out guide to close the door, as is usually necessary.

Preferably, at least one spring element is provided between the baking oven muffle and the baking tray, which prestresses the baking tray in the opening direction when the baking oven is in a closed position. The spring element does not have to be attached directly to the oven muffle and the food support, but can also be provided via the interposition of other components in order to prestress the food support in the opening direction. For example, the spring element can act on a synchronization means between the two pull-out guides or on a side rail in a detachable or non-detachable manner. As a result, when the baking oven is opened, the food support can be shifted at least partially in the opening direction in order to be more accessible. The pull-out movement generated by the spring element can be, for example, in a range between 2 cm and 30 cm, in particular 5 cm and 20 cm. The spring element can be designed, for example, as a bending spring that is detachably connected to the food support.

The food support preferably has at least one stop element made of an elastic material, for example rubber, silicone or another heat-resistant plastic, on the side facing the oven door. As a result, the prestressed food support can come into contact with the oven door in the closed position without loud knocking noises, and when the oven door is opened, the food support can be moved in the extension direction via the spring element.

An oven 1 comprises an oven muffle 2 which has two side walls 3 which are connected to one another via a floor 4 and a cover 5 . In an interior of the baking oven muffle 2 there is a pull-out guide 6 on a side wall 3, which is fixed with a stationary guide rail 7 on the side wall 3 or the ceiling 5. On the guide rail 7, an extension-extending center rail 8 is held so that it can move, on which a running rail 9 can move, with the moveable mounting preferably taking place via rolling elements. The running rail 9 is shorter in the longitudinal direction of the pull-out guide 6 than the guide rail 7 and the middle rail 8, in particular by more than 10%, preferably more than 20% shorter.

A side rail 10 is held on the running rail 9 and has vertical posts 11 between which horizontal bars 12 run. The side rail 10 can be attached to the running rail 9 in a non-detachable manner, for example by welding, or detachably, for example by means of clips, locking means, screws or other detachable fastening means. Two horizontal rods 12 form a receptacle for an edge 15 of a food support 14, which is designed as a baking tray in the illustrated embodiment, although grids or other food supports can also be used. The rods 12 are on one End portion 13 formed angled, so that in a front view according to Figure 1B an edge 15 of the food support 14 can be inserted between two horizontal bars 12 . On the upper horizontal bar 12 of a receptacle, a downwardly projecting projection 16 is formed in the rear area, in particular a V-shaped projection, which forms an anti-tip device and prevents the food support in the rear area from tipping upwards when it is on a front is charged. Instead of the projection 16, other holding means can also be provided for additional fixing of the food support.

In the Figure 2C It can be seen that the food support 14 has a downwardly protruding web or undercut 150 in the area of its edge 15, which rests on both sides on the angled front end section 13 of the lower rod 12 when the food support 14 is correctly positioned in the side grille 10. The angled end section 13 is inserted in a receptacle 152 open towards the bottom on the undercut 150 . This ensures, on the one hand, that the food support 14 cannot be pushed too far into the side rail 10 and, on the other hand, additional protection against tipping is provided. The undercut 150 can have an insertion bevel 151 at least in the rear end region, which allows the food support 14 to be pushed easily onto the rod. An insertion bevel 151 is preferably formed on both sides of the receptacle 152 .

In Figure 2D a food support 14 with an undercut 150 and insertion bevels 151 is shown. The undercut 150 can be provided on opposite sides of the food support 14 .

Viewed in the longitudinal direction of the pull-out guide 6, the food support 14 is at least 20% longer than the side rail 10, preferably at least 30% longer. The running rail 9 has approximately the same length as the side rail 10. The food support 14 protrudes in a front area over the side rail 10, whereas in the rear area it ends essentially flush with the side rail.

In the Figures 1A and 1B is the food support 14 in a retracted position, and the door of the oven can be closed.

If access to a part of the food support 14 is to be created during the preparation of food, it can be moved to a middle pull-out position be included in the Figures 2A and 2 B is shown. In this middle pull-out position, a front section of the food support 14, for example an area between 10 and 80%, is in front of the oven muffle 2, viewed in the longitudinal direction of the pull-out guide 6, while the remaining part of the food support 14 is arranged in the oven muffle 2, as is shown in FIG Figure 2B is shown. In this middle extension position, the side rail 10 is still completely in the oven muffle 2 and therefore does not pose a risk of injury. The running rail 9 is also still inside the oven muffle 2. If the food support 14 is now removed from this middle extension position, the oven door can be opened be closed, even if the rail 9 and the side rail 10 are not arranged in the maximum retraction position. Latching means are preferably provided on the pull-out guide 6 and/or the side rail 10 in order to be able to latch the food support 14 together with the side rail 10 in the middle extended position and thus to provide holding forces that prevent the food support 14 from accidentally moving beyond this middle extended position. In this exemplary embodiment, the locking means are designed as depressions 17 in the side wall 3 of the baking oven 1, into which a preferably spring-loaded roller 18 arranged on the vertical post 11 engages in the retracted, in the middle and in the extended position. Instead of the depression 17, a locking projection or another locking element could also be present, and instead of a roller 18, a projection, a spring element, or similar locking means could also be present. Alternatively, latching means can be provided between the running rail 9 and the guide rail 7 or between the running rail 9 and the side rail 10 .

In a non-inventive example, if the user wants to move the food support 14 further in front of the oven muffle 2, he can do so in accordance with Figures 3A and 3B make. By gently pulling on the food support 14, the locking means are disengaged and the food support 14 can be moved. In this position, the side rail 10 is also largely in front of the oven muffle. If the food support 14 is now removed, however, the side rail 10 and the running rail 9 protrude comparatively little from the baking oven muffle 2 . The side rail 10 can, for example, have a length in the longitudinal direction of the pull-out guide 6 of between 20% and 60% of the length of the food support 14 . The food support and side rails can be completely in front of the oven muffle.

In the illustrated embodiment, the side rails 10 include a Variety of horizontal bars 12, each recording for a food carrier 14 form. It is of course possible to adapt and vary the number of seats formed in this way to the type of oven. In addition, the pull-out guide 6 can also be arranged to the side of the side rail or below the side rail 10 instead of above the side rail 10 .

In order to increase the stability of a baking oven 1 according to the invention, at least one synchronization means 19, e.g. as a sheet metal or as a rod, can be arranged between the right and left side rails 10. The at least one synchronization means 19 is preferably located in a region of the side rail 10 that is vertically spaced from the pull-out guide 6 . In addition or as an alternative, the two pull-out guides can also be connected to one another. Releasable or non-releasable attachment means for the synchronization means 19 can be provided.

In the Figures 4A and 4B a modified exemplary embodiment of an oven 1 with an oven muffle 2 is shown. In the interior of the baking oven muffle 2 there is a pull-out guide 6 on a side wall 3 in each case, with a stationary guide rail 7 being arranged below a movable running rail 9 . The running rail 9 can be shorter than the guide rail 7 in the longitudinal direction of the pull-out guide 6. A modified side rail 10' is held on the running rail 9, which has vertical posts 11 and horizontal bars 12.

In the area of the pull-out guide 6, the side rail 10' has a profile 24, in particular a U-shaped profile 24, on which a support 25 is formed. As a result, the support 25 can be supported on the running rail 9, so that an additional fastening of the side rail 10′, as is necessary in the case of a hanging arrangement on an underside of the pull-out guide 6, can be omitted. The support 25 can be placed loosely on the running rails 9, with optional attachment, of course, being possible. The attachment can be detachable, e.g. by clips or screws, or non-detachable, e.g. by welding.

To secure the food support 14 on the side rail 10', the latter has an upward-pointing projection 26 on the lower horizontal bar 12 of the two horizontal bars 12, between which an edge 15 of the food support 14 is held, which projection 26 turns into a corresponding one on the edge 15 the food support 14 existing recess 27 engages from below. Instead of a projection 26, a pin or an embossing can also be present.

In figure 5 Another exemplary embodiment of an oven 1 with an oven muffle 2 is shown, in which two pull-out guides 6 are provided on an underside of the oven muffle 2 . It is also possible to provide only a single pull-out guide 6 instead of the two pull-out guides 6, which then carries two side rails 10''.

The pull-out guides 6 support a carrier 20, which supports a side rail 10" on opposite sides. For this purpose, the carrier 20 has two legs 21 protruding upwards, although other configurations of the carrier 20 for fixing the side rails 10" can also be provided.

All of the features described in detail for the first embodiment with regard to rail lengths, positions of the food supports and side rails, latching elements and synchronization means also apply to the two last-mentioned exemplary embodiments.

Each of the pull-out guides 6 shown can have a cover element, not shown, in the rear area of the guide rail. The cover protects the inside of the pull-out guide 6 from contamination and serves as a stop for the slide rail 9 when it is retracted.

In figure 6 is the in the Figures 1 to 3 shown oven shown in a modified embodiment. In addition to the exemplary embodiment described above, a spring element 30 in the form of a bending spring is arranged between the baking oven muffle 2 and the food support 14 . The spring element 30 is connected at one end 31 to the oven muffle, for example via a holder. A connecting piece 32 is provided at the opposite end, which rests against the food support 14 and is detachably connected to the food support 14 . The spring element 30 allows the food support 14 to move from the position in Figure 1A shown closed position when opening the oven door automatically moved in the opening direction. The movement generated by the spring element 30 facilitates access to the food support 14. Starting from this position, the food support 14 can then optionally be moved further in the extension direction or be moved again directly or via the oven door in the closing direction.

The spring element 30 is arranged between a rear wall of the baking oven muffle 3 and the food support 14 . Alternatively, the spring element 30 also be provided between the oven muffle 2 and the side rail 10 or between the guide rail 7 and the running rail 9. In any case, the food support 14 is directly or indirectly pretensioned in the opening direction via the spring element 30, with the oven door holding the food support 14 in the closed position in the closed position holds. An elastic stop element, for example on the edge 15, can be provided at a contact area between the food support 14 and the oven door, in order to avoid impact noises.
