Description

The invention relates to a holding and guiding device for a cooking appliance, which is designed for receiving food supports. The invention also relates to a cooking appliance with a cooking chamber which is delimited by walls of a muffle. The cooking appliance also includes a holding and guiding device, which is designed to receive a plurality of food supports in different levels and for horizontal displacement of the food support.

Various configurations of food supports and rail extension devices are known from the prior art. So here rail extension devices are known, on which only a food support can be placed and then pushed horizontally into the cooking or can be pulled out. These rail extension devices usually comprise a fixed rail, which is arranged on an inner side of a muffle wall, and a relatively movable track or sliding rail.

In addition, support grids are known which can also be arranged on the insides of these vertical walls of the muffle and which are rigid in themselves, wherein they have different levels, in which then food support can be introduced in plurality.

In addition, so-called baking carts are known, which are directly connected to a door for closing the cooking chamber and can be moved out horizontally. However, in the case of these baking carriages front-side access to the food carriers is not possible even when pulled out. The lateral accessibility is limited.

From the DE 102 40 146 A1 an embodiment of a cooking appliance is known, in which on the inner sides of a muffle horizontally oriented guide rails are arranged stationary, on which a relatively small carriage is arranged as a wrap and is relatively displaceable on the guide rail. On the carriage, a vertically oriented support member is arranged, which is rod-shaped. At this support part a plurality of grooves is arranged at a front edge into which food support can be hung at different levels. By such a configuration a plurality of food carriers arranged one above the other are simultaneously horizontally hineinschiebbar in the cooking chamber and pulled out.

Since the Gargutträger are mounted only with their rear end in these grooves, relatively large leverage forces on the vertical holding part and thus also on the carriage.

It is an object of the present invention to provide a holding and guiding device for Garggutträger and a cooking appliance, in which or in which a plurality of superposed Gargutträgern in the horizontal direction pushed into a cooking chamber and pulled out again, the device provided for this purpose lower mechanical leverage is exposed.

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

A holding and guiding device according to the invention is designed for receiving a plurality of food supports in different levels and for horizontal displacement of the food support. The shift of the food support is done together. An essential idea of the invention is to be seen in that the holding and guiding device has a arranged on a vertical wall of the muffle rail extraction device with at least one horizontally oriented fixed rail and at least one coupled to the fixed rail and relatively movable horizontally oriented displacement rail. The holding and guiding device further comprises at least one supporting grid with at least two receiving units, which are designed at different altitudes, for the food supports, the supporting grid being arranged on the sliding bar. By such a configuration, the mechanical coupling between the rail extraction device and the support grid, which is designed for receiving a plurality of food supports, is improved. The weight forces of the food supports act more uniformly on the rail extraction device a, and by the horizontally oriented fixed rail and the associated and also horizontally oriented displacement rail also the force effects and power redirections and the relative movement of the rails are improved.

It is thereby also a cooking appliance created, which is improved in terms of the assembly with multiple food supports in the motion guide with power coupling points. Nevertheless, the accessibility to the food carriers in the various levels for a user is still fully available.

The support grid is designed so that all arranged on the support grid Gargutträger be moved simultaneously and also over the same path with a horizontal displacement.

It is preferably provided that the support grid extends over at least half, in particular at least 80%, of the length of the displacement rail along the displacement rail and in particular between the ends of the displacement rail, whereby the above-mentioned advantages with regard to the more uniform mechanical coupling and force distribution is favored. The shifting behavior is thus more uniform and jerk-free, which is particularly in the case of extensive loading of the support grid with food supports and / or extensive loading of one or more food support with food comes into play.

In particular, the displacement 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 (viewed in the depth direction of the cooking appliance) vertically oriented support rod and extend between the support rods, the receiving units. The receiving units each have an upper and a lower guide rod, through which a guide slot for receiving and guiding a side edge of a food support is formed. This is a significant advantage over the cited prior art document, since thus the food support is mechanically connected over a relatively large length with the receiving unit and thus significantly lower leverage Act. The handling of the food support is thereby facilitated and the horizontal displacement of the support grid with the food supports is favored. In particular, the storage is accompanied by a lower wear.

Preferably, an upper guide rod forms an element of a tilt protection device for the food support in a different from the fully inserted position extended position. If the food support is thus pulled forward by a path with respect to the support grid, undesired tilting of the food support downwards is prevented in which this tilting movement is limited by the upper guide rod. The upper guide rod is therefore also a multifunctional component.

Preferably, the support grid on a front and a rear vertically oriented support rod, wherein extending between the support rods, a lower guide rod of a receiving unit, and formed separately to the supporting grid rod frame is formed, which has a vertically disposed above the lower guide rod upper guide rod , wherein a guide slot for receiving and guiding a side edge of a food support is formed by the guide rods, and the upper guide rod is an element of a tilt protection device for the food support.

It can be provided that the upper guide rod of the rod frame is spaced and 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 extends in particular vertically to the lower guide rod. By a specific embossing, whereby the upper guide rod is not rectilinear, formally and positionally formed an upper point-like boundary of the guide slot through the upper guide rod, which then also the anti-tipper is formed.

The two above-mentioned embodiments can also be combined in a bar frame.

In a further embodiment, the anti-tilt device is formed by the fact that a bracket is arranged on a lower guide rod, which is in one with a

Horizontal plane extending U-region is arranged parallel and spaced above the lower guide rod and thus has the upper guide rod integrated. In this embodiment, no separate rod frame is formed, but the bracket are integrated into the support grid.

In an advantageous embodiment, the anti-tilt device is multi-pronged and thus embodied in several planes, in particular analogously to the receiving units, and the upper guide rods are integrated in a bar frame which is separate from the carrier grid. As a result, the upper guide rods are stably connected and thus can withstand high forces. Furthermore, a positionally accurate arrangement of the upper guide rods to each other is achieved than to the respective lower guide rods.

Preferably, the bar frame is firmly connected to the at least one sliding rail. As a result, a mechanically stable connection is achieved. In particular, a movement coupling is thus obtained between the at least one displacement rail and the rod frame, so that the tilt protection is also independent of the extension position of the displacement rail of the same effect when the food support is pulled out in a certain position relative to the displacement rail forward, but still with a receiving unit is coupled.

It can be provided that the bar 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. Preferably, the bar frame in a front half of the length of the slide rail is attached to this and extends with its entire considered in the depth direction of the cooking device length within this front half 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. As a result, a slipping security of one or more food support can be prevented circumferentially and beyond a position assurance of a food support can be achieved.

In particular, one or more stops in their shape and / or in the dimension dimensions are designed so that pulled by a not undesirably high force by a user of the food support over this attack can be and thus even with a circumferential loading of a food support with food the handling for removal of the food support from the support grid is easily possible.

Preferably, it is provided that the support grid has a front and a rear vertically oriented support rod, and the displacement rail is connected to the front and / or the rear support rod. As a result, a mechanical coupling is formed quasi at the maximum spaced locations, whereby the lever forces are reduced and a uniform attachment and storage and coupling of the support grid is achieved with the sliding rail. Especially with increasing extraction of the sliding rail, the motion control is kept as smooth as possible here.

Preferably, the support rods are formed with embossments, in which the displacement rail extends. As a result, the installation space width and thus the expansion of the embodiment in the width direction of the cooking appliance is minimized.

The support grid is in particular completely constructed of rods, in which case the guide rods are to be mentioned here in addition to the vertical support rods.

It is preferably provided that the support grid is arranged non-destructively releasably on the sliding rail. As a result, the decomposition into individual parts can be carried out as desired, which is advantageous for assembly purposes and for cleaning purposes. In addition, the replacement of individual components is favored without the entire arrangement would have to be replaced.

It is preferably provided that the rail extraction device is arranged by at least one headband on the vertical wall of the muffle. By such a headband mechanical attachment and coupling with the vertical wall is favored.

In particular, it is provided that a retaining clip is C-shaped or Ω-shaped and has at least one retaining pin, which is arranged and formed in a central part of the specific shape. This retaining pin preferably extends horizontally and can engage in a receptacle in the vertical wall. By such an engagement, which can also be locked, on the one hand a support of the headband on the inside allows free of play, so that a full fit of the retaining bracket is made possible on the vertical wall. By such a support, the entire construction is then stably held on the vertical wall and even with heavier food supports, extensive loading of the support grid with food supports and / or food items a slipping security is achieved.

The headband with its specific shape therefore have significant advantages in the context.

Preferably, it is provided that a first vertically oriented headband is disposed in a rear Längendrittel the fixed rail, and a second vertically oriented headband is arranged in a front Längendrittel the fixed rail. The above-mentioned advantages are again emphasized here, so that the positionally accurate positioning and maintaining this position of the rail extraction device is maintained.

Preferably, it is provided that the rail extraction device has an upper horizontally oriented fixed rail and at least one coupled to the upper rail and relatively movable upper horizontally oriented sliding rail, and a lower horizontally oriented fixed rail and at least one coupled to the lower fixed rail and relatively movable lower horizontally oriented sliding rail has. The support grid is connected to the upper and the lower slide rail. By such a design of the rail extraction device, the mechanical stability and leadership functionality is further improved.

It is preferably provided that two separate rail extraction devices are arranged on opposite vertical walls of the muffle and in each case a support grid is connected to at least one displacement rail of a respective rail extraction device. The support grid are in particular not mechanically connected to each other. They are coupled only by one or more food carriers.

Since the sliding rail is relatively small in height compared to the support grid and is preferably arranged between two superimposed receiving units of the support grid, also a lateral and front unrestricted accessibility of a user to the respective food supports on the different levels is made possible by this configuration ,

It is preferably provided that the fixed rail and the sliding rail are locked to each other in a pushed together end position and / or locked in a maximum extended end position. As a result, these very specific exposed layers are secured to each other, so that an undesirable relative displacement is prevented each other. A user can thus handle the food support easier or other food supports do not interfere with the handling of a specific selected food support.

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.

By an inventive embodiment of the cooking appliance or an advantageous embodiment of a multi-pronged device for food support is created, which can be simultaneously retracted and extended, without a circumferential structure with many components, as is the case for example with a baking wagon, is needed. On the other hand, the component-reduced and in the components, in particular the rail extraction device, space-specific very minimized configuration is still known over known from the prior art designs with advantages in terms of low wear, occurring force application points and general user-friendly motion control improved.

Further features of the invention will become apparent from the claims, the figures and the description of the figures.

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

In Fig. 1 a cooking appliance 1 is shown, which is designed as a baking oven. The cooking appliance 1 includes by way of example also a hob 2 with cooking zones 3, 4, 5 and 6, which are also to be understood in position and number by way of example only. The cooking appliance 1 further comprises an operating device 7, which may have a display unit 8 and controls 9 and 10, wherein also here the location, the number and the design of the display unit 8 and / or the controls 9 and 10 are to be understood merely by way of example. The cooking appliance 1 comprises a cooking chamber 11 which passes through walls of a muffle 12 is limited. On the front side, the muffle 12 comprises a feed 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 bottom 18.

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

The holding and guiding device 19 is designed for receiving this plurality of food supports 20, 21 at different altitudes in the vertical direction of the household appliance or the gas appliance 1 and also designed for horizontal displacement of the food supports 20 and 21 together and over the same displacement.

The holding and guiding device 19 has a rail extension device 22 arranged on the vertical wall 14, whereas, in addition, a further rail extraction device 23 is arranged on the opposite vertical wall 15. Each of the two rail extraction devices 22 and 23 has at least one horizontally oriented fixed rail, which is arranged and fixedly attached to the respective vertical wall 14 and 15, and a sliding rail mechanically coupled to the respective fixed rail and relatively movable horizontally oriented.

The holding and guiding device 19 further comprises on the opposite sides of a food support 20 and 21, a separate support grid or a grid frame. These support grids are designed so that they have on at least two different altitudes (in the vertical direction and thus in the y direction) and thus on at least two different insertion levels formed receiving units for the food supports 20, 21. The food supports are thus in these receiving units on the support grids, and the support grid are arranged on the sliding rails of the rail extraction devices 22 and 23.

In Fig. 2 is an embodiment of a holding and guiding device 19 is shown in a perspective view, as for example on the vertical wall 14th can be arranged. The holding and guiding device 19 here comprises a rail extraction device 22 which has a first upper fixed rail 24 and a second lower fixed rail 25 extending parallel thereto and 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 displacement rail 27, wherein the further displacement rail 27 is horizontally displaceable relative to the lower fixed rail 25.

The rail extraction device 22 extends with its longitudinal axis A which also defines the longitudinal extension 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 by vertically oriented headband 28 and 29, which also spaced and parallel to each other, connected. The retaining clips 28 and 29 are C-shaped or Ω-shaped. They have in their middle parts retaining pins 30 and 31 which extend horizontally in the direction of the vertical wall 24 and inserted there in corresponding receptacles and optionally latched. The brackets 28 and 29 are supported on the inside of the vertical walls 14. Such a framework is highly stable and resilient.

In addition, in Fig. 2 to recognize that the already mentioned support grid 32 is constructed entirely of rods, here at a front end a first support rod 33 and at a rear end a second support rod 34, wherein the support rods 33 and 34 are vertically oriented and parallel to each other , In the horizontal direction between the support rods 33 and 34 guide rods are formed, each pair of a receiving unit 35 form, the clarity serving only the upper receiving unit 35 is provided with a corresponding reference numeral. This receiving unit 35 has a horizontally oriented upper guide rod 36 and a parallel thereto lower guide rod 37. In between, a guide area is virtually formed, in which a side edge of a food support 20, 21 engage and can be guided along or held.

As from the illustration in Fig. 2 can be seen, it is provided in this embodiment, that the displacement rail 26 extends substantially over the length of the support grid 32 and connected at its front end to the front support bar 33, in particular is latched, and with its rear end to the rear support bar 34th connected, in particular is locked. The same is also provided in the lower displacement rail 27. As can also be seen, the displacement rails 26 and 27 are so small in their height that they fit quasi between two receiving units 35 positionally and thus the accessibility side and front of the arranged in receiving units 35 Gargutträgern for a user is easily possible , The slide rails 26 and 27 are substantially 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 embodiment according to Fig. 2 Here is a rail extraction device 22 is shown, which has only a fixed rail 24 and a sliding rail 26. The headband 28 and 29 with the retaining pins 30 and 31 are also provided here, but designed significantly smaller in vertical height. In the embodiment according to Fig. 3 the rail extraction device 22 is attached approximately at the central height of the support grid 32 to the front support rod 33 and the rear support rod 34, wherein analogous to the embodiment in FIG Fig. 2 in turn, a non-destructively releasable connection of the displacement rail 26 is formed.

In Fig. 4 is shown in a perspective view, the muffle 12. In addition, the support grid 32 with the also in Fig. 3 shown rail extraction device 22 shown. The displacement rail 26 is here extended substantially maximum and the example Gargutträger 20 and 21 arranged with their opposite side edges in receiving units 35.

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

In Fig. 6 is in a further perspective view of the muffle 12 shown in particular the vertical wall 14, in which case a holding and guiding device 19, as shown in Fig. 2 was shown is installed. This holding and guiding device 19 is shown with its rail extraction device 22 in the extended state. In this embodiment, a receptacle 38 for the mounting pin or the retaining pin 30 is shown on the headband 28. Accordingly, a receptacle 39 for the retaining pin 31 is shown.

In Fig. 7 is in 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 has been explained, in which case the side edge 21a rests 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 verschiebegesichert forward. In particular, a corresponding stop is also formed in a rear region 41, so that here too a corresponding position assurance is achieved.

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

In Fig. 9 is shown in a corresponding representation, a second embodiment of a front stop 40. When displayed in Fig. 8 is in the context of an additional rod member above the lower guide rod 37 in the horizontal direction and thus arranged in the width direction, which is in the horizontal displacement of the flange and thus also the side edge 21a of the food support 1. In the embodiment in Fig. 9 on the other hand, the lower guide rod 37 has an embossment which rises in the vertical direction, so that here too the side edge 21a abuts correspondingly.

The stops 40 in their various embodiments are formed so that they can be overcome by a not undesirably high expenditure of force by a user when lifting and pulling out of the food support 20, 21 and thus here, therefore, a corresponding handling is possible.

In Fig. 10 a further embodiment of a holding and guiding device 19 is shown in a perspective view. By way of example, a single rail extraction device 22 is shown here. The displacement rail 26 is arranged here in embossing 33a and 34a of the support rods 33 and 34 extending. In a similar manner, such an arrangement can also be used in an embodiment of a rail extraction device 22, as shown in FIG Fig. 2 or 6 shown to be trained. The embossments 33a and 34a are preferably shaped so that the displacement rail 26 is encompassed to some extent C-shaped and thus also held accordingly.

In Fig. 11 is another embodiment in a perspective view, in which the rail extraction device is shown in a collapsed state shown. In this example, a support grid 32 and a separate, composed of rods bar frame 42 is formed. The bar frame 42 comprises two parallel, in particular vertically oriented bars 44 and 46, to which U-shaped elements are attached. The U-shaped elements each comprise upper guide rod 36 which is spaced and parallel to a lower guide rod 37 and forms with the adjacent lower guide rod 37 a guide slot or a receiving unit 35 for a side edge 21a of a food support 20, 21. As can be seen in the example, the upper guide rods 36 are substantially shorter than the lower guide rods 37. In the example, they amount to a maximum of one third of the length, which measures in the depth direction and thus in the z-direction of the cooking device 1, the lower guide rod 37th By the bar frame 42 and in particular the upper guide rods 36 elements of an embodiment of a tilt protection device are formed.

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

In Fig. 11 is further provided that the rods 44 and 46 are embossed and thereby also U-shaped protrusions are formed, the lower creases 43 and 45 have. These creases then also upper limits of a receiving unit 35 are created and also Kippschutzvorrichtungselemente formed.

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

In Fig. 12 another example is shown in which, unlike the example in Fig. 11 the number of embossments in the bars 44 and 46 is increased to form upper guide bars and also anti-tilt device elements. Only at the top of a U-shaped bracket is formed in a parallel horizontal plane to the lower guide rod 37.

In Fig. 13 an example is shown in which no separate bar frame 42 is present, but bracket 47 are arranged on a forming a receiving unit 35 associated lower guide rod 37. A bracket 47 has in a horizontal plane (xz-plane), which is parallel to the lower guide rod 37, a U-shaped molding, which comprises an upper guide rod 36 which is spaced and parallel to the lower guide rod 37. Again, a tilt protection device is formed and the upper guide rod 36 forms the upper stop thereto.

Also in the versions according to Fig. 11 to 13 the support grid 32 is connected to the displacement rails 26 and 27 and thereby motion-coupled or motion-fixed.
