Description

The invention relates to a holding and guiding device for a cooking appliance, which is designed to receive food carriers. The invention also relates to a cooking appliance with a cooking space which is delimited by walls of a muffle. The cooking device also includes a holding and guiding device which is designed to accommodate a plurality of food carriers in different planes and to move the food carriers horizontally.

A variety of designs of food carriers and rail pull-out devices are known from the prior art. Rail pull-out devices are known here, on which only a food support can be placed and then inserted or pulled out horizontally into the cooking space. These rail pull-out devices usually comprise a fixed rail, which is arranged on the inside of a muffle wall, and a running rail or sliding rail that can be moved relative to it.

The DE 77 08 782 U1 describes an oven with a collapsible food carrier, which is guided with its underframe in guide rails.

In addition, support grids are known, which can also be arranged on the inside of these vertical walls of the muffle and which are rigid in themselves, having different levels, in which food carriers can then be introduced in a plurality.

In addition, so-called baking trolleys are known which are connected directly to a door for closing the cooking space and can be moved out horizontally. With these baking trays, however, front access to the food carriers is not possible even when they are pulled out. Lateral access is also restricted.

From the DE 102 40 146 A1 An embodiment of a cooking device is known in which horizontally oriented guide rails are arranged fixedly opposite on the inside of a muffle, on which a relatively small slide is arranged as a wrap and can be displaced relative to it on the guide rail. A vertically oriented holding part is arranged on the slide and is designed like a rod. On this holder part, a plurality of grooves are arranged on a front edge, into which food carriers can be hung on different levels. By means of such a configuration, a plurality of items to be cooked arranged one above the other can simultaneously be pushed and pulled horizontally into the cooking space.

Since the food carriers are only hooked into these grooves with their rear ends, relatively large leverage forces are exerted on the vertical holding part and thus also on the slide.

It is an object of the present invention to provide a holding and guiding device for food items and a cooking device, in which or in which a plurality of food items arranged one above the other can be pushed horizontally into and out of a cooking space, the device provided for this purpose is exposed to lower mechanical leverage.

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

A holding and guiding device according to the invention is designed to accommodate a plurality of food carriers in different planes and for horizontal displacement of the food carriers. The food carriers are moved together. An essential idea of the invention is that the holding and guiding device has a rail pull-out device arranged on a vertical wall of the muffle with at least one horizontally oriented fixed rail and at least one horizontally oriented sliding rail coupled to the fixed rail and movable relative thereto. The holding and guiding device furthermore comprises at least one support grid with at least two receiving units for the food carriers formed at different heights, the support grid being arranged on the sliding rail. With such a configuration mechanical coupling between the rail pull-out device and the support grid, which is designed to accommodate several food carriers, improved. The weight of the food carriers acts more evenly on the rail pull-out device, and the horizontally oriented fixed rail and the associated and also horizontally oriented sliding rail also improve the force effects and force diversions and the relative movement of the rails.

This also creates a cooking device which is improved with regard to the placement of several food carriers in the movement control with force coupling points. Nevertheless, the user still has full accessibility to the food carriers in the various levels.

It is provided that the support grid is detachably arranged on the sliding rail in a non-destructive manner. As a result, the disassembly into individual parts can be repeated as often as desired, which is advantageous for assembly purposes and for cleaning purposes. In addition, the replacement of individual components is also favored without having to replace the entire arrangement.

The supporting grid has a front and a rear, vertically oriented holding rod, a lower guide rod of a receiving unit extending between the holding rods, and a rod frame which is formed separately from the supporting grid and which, viewed in the vertical direction, has an upper guide rod arranged above the lower guide rod, wherein the guide rods form a guide link for receiving and guiding a side edge of a food support, and the upper guide rod is an element of an anti-tip device for the food support.

The rod frame is firmly connected to the at least one sliding rail. This ensures a mechanically stable connection. In particular, a movement coupling between the at least one sliding rail and the rod frame is thus obtained, so that the tilt protection also has the same effect regardless of the pull-out position of the sliding rail when the food support is in a certain position Position is pulled forward relative to the slide rail, but is still coupled to a receiving unit.

The support grid is designed such that, in the event of a horizontal displacement, all of the food carriers arranged on the support grid are moved simultaneously and also via the same path.

It is preferably provided that the support grid extends over at least half, in particular at least 80%, of the length of the sliding rail along the sliding rail and in particular between the ends of the sliding rail, as a result of which the above-mentioned advantages with regard to the more uniform mechanical coupling and force distribution is favored. The shifting behavior is thus more even and jerk-free, which is particularly important when the load grid is extensively equipped with food carriers and / or when one or more food carriers are loaded extensively with food.

In particular, the sliding rail extends over at least 70%, in particular at least 85%, of the length of the fixed rail in the direction of the longitudinal axis of the fixed rail.

It is preferably provided that the support grid has a front and a rear holding rod (viewed in the depth direction of the cooking appliance) which is oriented vertically and the receiving units extend between the holding rods. The receiving units each have an upper and a lower guide rod, through which a guide link for receiving and guiding a side edge of a food support is formed. This is a significant advantage over the cited prior art, since the food support is thus mechanically connected to the receiving unit over a relatively long length and thus significantly lower leverage acts. The handling of the food support is thereby facilitated and the horizontal displacement of the support grid with the food supports is also favored. Storage, in particular, is associated with less wear.

An upper guide rod preferably forms an element of an anti-tip device for the food support in an extended position different from the fully inserted position. If the food carrier is thus one way opposite the Pulling the support grid forward prevents an undesired tilting of the food carrier downwards, in that this tilting movement is limited by the upper guide rod. The upper guide rod is therefore also a multifunctional component.

It can be provided that the upper guide rod of the rod frame is spaced apart and runs parallel to the lower guide rod. In a further embodiment, the upper guide rod extends only with its diameter thickness in the direction parallel to the lower guide rod and thus runs in particular vertically to the lower guide rod. Due to a specific embossing, whereby the upper guide rod is not designed in a straight line, an upper point-like limitation of the guide link is formed by the upper guide rod in terms of shape and position, as a result of which the anti-tip is also formed.

The two versions mentioned above can also be combined in a rod frame.

In an advantageous embodiment, the anti-tip device is multilevel and thus in several planes, in particular, is designed analogously to the receiving units, and the upper guide rods are integrated in a rod frame which is separate from the supporting grid. As a result, the upper guide rods are stably connected and can therefore withstand high forces. Furthermore, a positionally accurate arrangement of the upper guide rods with respect to one another than with the respective lower guide rods is achieved.

It can be provided that the rod frame, viewed in the depth direction of the cooking appliance, has a maximum of half the length of the support grid, in particular a maximum of one third of the length. The rod frame is preferably in a front half length Sliding rail attached to this and extends with its entire length viewed in the depth direction of the cooking device within this front half of the length.

It is preferably provided that an upper and / or a lower guide rod has a front and / or rear stop for the food support. In this way, a security against slipping of one or more items to be cooked can be prevented to a large extent and a position of a item to be secured can also be secured.

In particular, one or more stops are designed in terms of their shape and / or their dimensions so that the food carrier can be pulled over this stop by a not undesirably high expenditure of force by a user and thus also the handling for a comprehensive loading of a food carrier with food Removing the food support from the support grid is easily possible.

It is preferably provided that the support grid has a front and a rear vertically oriented support rod, and the sliding rail is connected to the front and / or the rear support rod. As a result, a mechanical coupling is formed at the maximally spaced locations, which also reduces the lever forces and ensures uniform attachment and storage and coupling of the support grid to the sliding rail. Especially with increasing pulling out of the slide rail, the movement is kept as smooth as possible.

The holding rods are preferably formed with embossments into which the sliding rail extends. As a result, the installation space width and thus the extent of the configuration in the width direction of the cooking appliance is minimized.

The supporting grid is in particular made up entirely of rods, the guide rods also being mentioned here in addition to the vertical holding rods.

It is preferably provided that the rail pull-out device is arranged on the vertical wall of the muffle by at least one holding bracket. By such Bracket is favored the mechanical attachment and coupling to the vertical wall.

In particular, it is provided that a holding bracket is shaped like a C or Ω and has at least one holding pin which is arranged and formed in a central part of the specific shape. This holding pin preferably extends horizontally and can engage in a receptacle in the vertical wall. Such an engagement, which can also be locked, on the one hand supports the holding bracket on the inside without play, so that a tight fit of the holding bracket on the vertical wall is made possible. With such a support, the entire construction is then held stably on the vertical wall, and security against slipping is achieved even with heavier food carriers, extensive loading of the supporting grid with food carriers and / or food items.

The brackets with their specific shape therefore have significant advantages in this context.

It is preferably provided that a first vertically oriented retaining bracket is arranged in a rear longitudinal third of the fixed rail, and a second vertically oriented retaining bracket is arranged in a front longitudinal third of the fixed rail. The advantages mentioned above are emphasized here again, so that the exact positioning and maintenance of this position of the rail pull-out device is maintained.

It is preferably provided that the rail pull-out device has an upper horizontally oriented fixed rail and at least one upper horizontally oriented sliding rail coupled to the upper fixed rail and movable relative thereto, and a lower horizontally oriented fixed rail and at least one lower horizontal coupled to the lower fixed rail and movable relative thereto oriented slide rail. The support grid is connected to the upper and lower slide rails. Such a configuration of the rail pull-out device further improves the mechanical stability and guide functionality.

It is preferably provided that two separate rail pull-out devices are arranged on opposite vertical walls of the muffle and one supporting grid is connected to at least one sliding rail of a respective rail pull-out device. The support grids are in particular not mechanically connected to one another. They are only coupled by one or more food carriers.

Since the height of the slide rail is relatively small in comparison to the support grid and is preferably arranged between two support units of the support grid arranged one above the other, this configuration also enables unrestricted lateral and front accessibility of a user to the respective food carriers on the different levels .

It is preferably provided that the fixed rail and the sliding rail are locked to one another in a pushed-together end position and / or are locked in a maximally extended end position. This also secures these very specific exposed positions to one another, so that an undesired relative displacement to one another is prevented. A user can thus handle the food carriers more easily, or other food carriers do not interfere with handling on a specific selected food carrier.

Furthermore, the invention comprises a cooking appliance which comprises at least one holding and guiding device according to the invention or an advantageous embodiment thereof.

An inventive design of the cooking device or an advantageous embodiment thereof creates a multi-level device for food carriers which can be retracted and extended at the same time without the need for a comprehensive structure with many components, as is the case, for example, with a baking trolley. On the other hand, the component-reduced configuration, which is very minimal in terms of installation space, in the components, in particular the rail pull-out device, is nevertheless improved compared with designs known from the prior art, with advantages in terms of low wear, occurring force introduction points and general user-friendly movement guidance.

The Figures 2-10 show exemplary embodiments that do not belong to the scope of protection, since they do not show a rod frame (42) with upper guide rods (36). However, the figures show other important aspects of the invention. Identical or functionally identical elements are provided with the same reference symbols in the figures.

In Fig. 1 a cooking device 1 is shown, which is designed as an oven. The cooking appliance 1 also includes, for example, a hob 2 with cooking zones 3, 4, 5 and 6, which are also to be understood as examples and in terms of position and number. The cooking appliance 1 also includes an operating device 7, which can have a display unit 8 and operating elements 9 and 10, the location, the number and the configuration of the display unit 8 and / or the operating elements 9 and 10 also being understood here only by way of example. The cooking device 1 comprises a cooking space 11, which passes through walls of a muffle 12 is limited. At the front, the muffle 12 comprises a loading opening which can be closed by a door 13. The muffle 12 comprises lateral vertical walls 14 and 15 as well as a rear wall 16, a top wall 17 and a floor 18.

In addition, the cooking device comprises a holding and guiding device 19, which is designed to receive a plurality of food supports 20, 21. The food supports can be gratings, grill pans or fat pans and baking trays.

The holding and guiding device 19 is designed to receive this plurality of food carriers 20, 21 viewed at different heights in the vertical direction of the household appliance or the gas appliance 1 and, moreover, is designed for the horizontal displacement of the food carriers 20 and 21 together and via the same displacement path.

The holding and guiding device 19 has a rail pull-out device 22 arranged on the vertical wall 14, whereas, in addition, a further rail pull-out device 23 is arranged on the opposite vertical wall 15. Each of the two rail pull-out devices 22 and 23 has at least one horizontally oriented fixed rail which is arranged and fixed in a stationary manner on the respective vertical wall 14 or 15, and a horizontally oriented sliding rail which is mechanically coupled to the respective fixed rail and is movable relative thereto.

The holding and guiding device 19 also includes a separate support grid or a grid frame on the opposite sides of a food support 20 and 21. These supporting grids are designed in such a way that they have receiving units for the food carriers 20, 21 formed at least two different heights (in the vertical direction and thus in the y direction) and thus on at least two different insertion levels. The food carriers are thus in these receiving units on the support grids, and the support grids are arranged on the sliding rails of the rail pull-out devices 22 and 23.

In Fig. 2 an embodiment of a holding and guiding device 19 is shown in a perspective view, such as that on the vertical wall 14 can be arranged. The holding and guiding device 19 here comprises a rail pull-out device 22 which has a first upper fixed rail 24 and a second lower fixed rail 25 which runs parallel to it and is spaced apart. The upper fixed rail 24 is connected to an upper sliding rail 26, which is movable relative to the fixed rail 24. In addition, the lower fixed rail 25 is connected to a further sliding rail 27, the further sliding rail 27 being horizontally displaceable relative to the lower fixed rail 25.

The rail extension device 22 extends with its longitudinal axis A which also defines the longitudinal extent of the fixed rails and the sliding rails. The longitudinal extent is measured in the depth direction (z direction) of the cooking device 1.

In Fig. 2 the extended state of the slide rails 26 and 27 is shown.

As can be seen, the fixed rails 24 and 25 are connected by vertically oriented holding brackets 28 and 29, which also extend at a distance and parallel to one another. The brackets 28 and 29 are shaped like a C or Ω. They have holding pins 30 and 31 in their central parts, which extend horizontally in the direction of the vertical wall 24 and are inserted there in corresponding receptacles and, if appropriate, locked. The holding brackets 28 and 29 are supported on the inside of the vertical walls 14. Such a scaffolding is highly stable and resilient.

In addition, in Fig. 2 It can be seen that the support grid 32 already mentioned is made up entirely of rods, here having a first holding rod 33 at a front end and a second holding rod 34 at a rear end, the holding rods 33 and 34 being oriented vertically and running parallel to one another . In the horizontal direction between the holding rods 33 and 34, guide rods are formed, each of which forms a receiving unit 35 in pairs, only the upper receiving unit 35 being provided with a corresponding reference number for the sake of clarity. This receiving unit 35 has a horizontally oriented upper guide rod 36 and a lower guide rod 37 running parallel thereto. In between, a guiding area is formed, in which a side edge of a food support 20, 21 engages and can be guided or held along.

As shown in Fig. 2 It can be seen in this exemplary embodiment that the sliding rail 26 extends essentially over the length of the support grid 32 and is connected, in particular latched, with its front end to the front holding rod 33 and with its rear end to the rear holding rod 34 connected, in particular locked. The same is also provided for the lower slide rail 27. As can also be seen, the slide rails 26 and 27 are so small in their overall height that they virtually fit positionally between two receiving units 35 and thus the accessibility to the side and front of the food carriers arranged in receiving units 35 is easily possible for a user . The slide rails 26 and 27 are essentially as long as the fixed rails 24, 25.

In Fig. 3 a further embodiment of a holding and guiding device 19 is shown in a perspective view. In contrast to the design according to Fig. 2 a rail pull-out device 22 is shown here, which has only one fixed rail 24 and one sliding rail 26. The holding brackets 28 and 29 with the holding pins 30 and 31 are also provided here, but are made significantly smaller in their vertical height. In the design according to Fig. 3 the rail pull-out device 22 is fastened to the front holding rod 33 and the rear holding rod 34 approximately at the central height of the support grid 32, here analogously to the configuration in FIG Fig. 2 in turn, a non-destructive detachable connection of the slide rail 26 is formed.

In Fig. 4 the muffle 12 is shown in a perspective view. In addition, the support grid 32 with the in Fig. 3 shown rail pull-out device 22. The slide rail 26 is here essentially extended to the maximum and the exemplary food supports 20 and 21 are arranged with their opposite side edges in receiving units 35.

In Fig. 5 12 is a perspective view of the embodiment of the holding and guiding device 19 according to FIG Fig. 4 shown, here a food support 21 shown here is arranged extended forward on the support grid 32.

In Fig. 6 is shown in a further perspective view the muffle 12, in particular the vertical wall 14, with a holding and guiding device 19, as shown in FIG Fig. 2 was shown, is installed. This holding and guiding device 19 is shown with its rail pull-out device 22 in the extended state. In this embodiment, a receptacle 38 for the fastening pin or the holding pin 30 on the holding bracket 28 is shown. Correspondingly, a receptacle 39 for the holding pin 31 is also shown.

In Fig. 7 is a further perspective view of the food support 1 in a position in the holding and guiding device 19, as in Fig. 3 , 4 and 5 was explained, shown, the side edge 21a here resting on a lower guide rod 37 of the receiving unit 35.

It can be seen that the lower guide rod 37 has a stop 40 at its front end, so that the food support 21 is secured against displacement to the front. In particular, a corresponding stop is also formed in a rear region 41, so that a corresponding position securing is also achieved here.

In Fig. 8 a first exemplary embodiment of a front stop 40 is shown in an enlarged illustration.

In Fig. 9 a second embodiment of a front stop 40 is shown in a corresponding illustration. When represented in Fig. 8 In this context, an additional bar element is arranged above the lower guide rod 37 in the horizontal direction and thus in the width direction, which is in the horizontal displacement path of the flange and thus also of the side edge 21a of the food support 1. When designing in Fig. 9 on the other hand, the lower guide rod 37 has an embossment which rises in the vertical direction, so that the side edge 21a also strikes accordingly here.

The stops 40 in their various designs are formed in such a way that they can be overcome by an undesirably high expenditure of force by a user when lifting and pulling out the food carrier 20, 21, and this also enables appropriate handling here.

In Fig. 10 a further embodiment of a holding and guiding device 19 is shown in a perspective view. A single-rail rail pull-out device 22 is shown here by way of example. The slide rail 26 is arranged here in embossments 33a and 34a of the holding rods 33 and 34. Correspondingly, this can also be done in a configuration of a rail pull-out device 22 as shown in Fig. 2 or 6 is shown. The embossments 33a and 34a are preferably shaped in such a way that the sliding rail 26 is encompassed to a certain extent in a C-shape and is therefore also held here appropriately.

In Fig. 11 Another embodiment is shown in a perspective view, in which the rail pull-out device is shown in a pushed-together state. In this example, a support grid 32 and a separate rod frame 42 constructed from rods are formed. The rod frame 42 comprises two parallel, in particular vertically oriented rods 44 and 46, to which U-shaped elements are fastened. The U-shaped elements each comprise an upper guide rod 36 which is spaced apart and arranged parallel to a lower guide rod 37 and forms a guide link or a receiving unit 35 for a side edge 21a of a food carrier 20, 21 with the adjacent lower guide rod 37. As can be seen in the example, the upper guide rods 36 are considerably shorter than the lower guide rods 37. In the example, they are a maximum of one third of the length of the lower guide rod 37, which is measured in the depth direction and thus in the z direction of the cooking device 1 The rod frame 42 and in particular the upper guide rods 36 form elements of an exemplary embodiment of an anti-tip device.

Likewise, the upper guide rods 36 of the other examples explained so far also form elements of anti-tip devices for a food support 20, 21.

In Fig. 11 it is further provided that the bars 44 and 46 are embossed and thereby also U-shaped bulges are formed which have lower kinks 43 and 45. These kinks then also create upper boundaries of a receiving unit 35 and also form anti-tipper elements.

The rod frame 42 is welded to the slide rails 26 and 27.

In Fig. 12 Another example is shown, in which, in contrast to, for example, in Fig. 11 the number of embossments in the bars 44 and 46 to form upper guide bars and also anti-tip devices is increased. Only at the top is a U-shaped bracket in a parallel horizontal plane to the lower guide rod 37.

Also in the versions according to 11 to 12 the support grid 32 is connected to the sliding rails 26 and 27 and is thereby motion-coupled or motion-fixed.
