Definitions

  • the invention relates to a grid for the preparation of preparation material, with a support area for the preparation material and a frame which surrounds the support area. Furthermore, the invention relates to a cooking appliance, in particular an oven, with a cooking chamber and a corresponding grid.
  • grilles or baking gratings can be inserted into a cooking chamber of a baking oven and arranged on these foodstuffs so that they can be prepared in the preparation room.
  • ovens are known in which such grids can be inserted and positioned in connection with arranged below baking trays or grill pans in muffle wall formed receiving and guiding devices.
  • This is from the WO 2007/077163 A1 a known embodiment, in which the grid has in its extension plane at the edge regions of formations, which allows a precise assembly with the underlying baking sheet or grill pan. The two components mentioned can be held stable in position to each other.
  • an oven in which a grid has an upwardly oriented elevation or curvature.
  • this curvature in the front region abuts against a stop of the slide track of the receiving and guiding device.
  • This stop can be overcome and the grid can be pulled out obliquely upwards.
  • the curvature has a height such that it substantially corresponds to the height of the slide track.
  • the design for tilt prevention of the grid is relatively insufficient and beyond the handling for insertion and removal relatively expensive and requires relatively many unusual movements.
  • An inventive grid for the preparation of preparation material comprises a support area on which the preparation material can be positioned.
  • the grid comprises a frame which surrounds the support area.
  • the grid has at least one stiffening element, which is arranged on the frame and extends between two partial elements of the frame.
  • the stiffening element is attached to sub-elements of the frame and extends over the entire length of the frame.
  • the stiffening elements are thus oriented in particular in the longitudinal direction of the frame and preferably arranged parallel to the receiving area. This allows a particularly suitable stiffening in terms of tilting in the longitudinal direction.
  • the stiffening element is rod-shaped and has at least one embossment.
  • embossing the rigidity of the stiffening element can be further improved, wherein in addition a multifunctional design of the stiffening element can be achieved by an individually shaped embossing. Because in addition to an increased bending stiffness of this stiffening element can then have a further functionality.
  • the embossing is trapezoidal.
  • the embossing extends over at least half, in particular at least three quarters, of the length of the stiffening element.
  • Such embossing makes it possible to produce a particularly good tension in such a way that a self-bending of the grid can be prevented.
  • the stiffening element is arranged in the width of the grid between the support area and a lateral sub-element of the frame. Neither the bearing surface of the bearing area is thereby impaired and impaired nor impair the function of the frame.
  • the embossing of the stiffening element extends below the level of the support area.
  • the stiffening element can then be designed as a pressure rod.
  • the embossing is shaped so that tilting or rocking of the grid is avoided and a stable positioning and installation is ensured.
  • the embossing of the stiffening element extends above the level of the support area.
  • the stiffening element is thus formed as a pull rod, which ensures the stiffening by a quasi-bridge-like survey.
  • a functionality can be ensured as a handle. The grid can thus be easily taken by a user on this embossing and transported accordingly.
  • the stiffening element may be positioned on the grid, that it additionally as a guide element or can be used as a management staff. This means that the stiffening element preferably during insertion and withdrawal of the grid in a Sliding track of a recording and guiding device in a cooking chamber of a cooking appliance outside the slide track on the gate elements is applied laterally. The stiffening element is thus guided along with its lateral edge on lateral flanks of the link elements. Tilting or jamming of the grid during insertion or withdrawal into or out of the preparation room can thus be avoided.
  • the receiving and guiding device is stationary. This means that the receiving and guiding device considered in itself has no moving parts.
  • the receiving and guiding device is designed as a telescopic device. Even with such an embodiment, the grid can be easily inserted and removed again.
  • the grid comprises at least one connecting part, which is connected to the stiffening element and a sub-element of the frame and / or a transverse strut of the support area.
  • the connecting part By such an additional connection of the stiffening element to other components of the frame by means of the connecting part, the flexural rigidity can be increased again.
  • the grid is relatively large and thus also the stiffening element is relatively long in the form of a rod, thus the inherent rigidity of this stiffening element can be substantially improved by the connecting part or the corresponding connection.
  • each of these connecting parts may be connected to a sub-element of the frame and / or a transverse strut of the support area.
  • An inventive cooking appliance is designed in particular as a baking oven.
  • the cooking appliance comprises a cooking chamber and a grid according to the invention or an advantageous embodiment thereof.
  • the cooking appliance comprises a receiving and guiding device, which is arranged in the preparation space, and in which the grid can be inserted and withdrawn to position it in the preparation room or to remove it.
  • This receiving and guiding device can be designed as a fixed or as a telescopic device.
  • Fig. 1 is shown in a perspective view of a trained as a baking oven 1 cooking appliance.
  • the oven 1 comprises a muffle 2, the walls of which define a cooking space 3 which constitutes a preparation space.
  • the muffle 2 Towards the front, the muffle 2 comprises an opening 4, which serves as a charging opening for introducing objects into the preparation space 3. This opening 4 is closed by a door 5.

  • the two link elements 18 and 19 are trapezoidal.
  • each a pull-stop element 16 and 17 are formed.
  • the pull-stop element 16 is realized by embossing in the sub-element 13c downwards and thus opposite to the embossing of the link element 18. Moreover, viewed in the longitudinal direction, it is formed in front of the link element 18 and thus closer to the front frame element 13a. The same applies to the pull-stop element 17 in the rod or sub-element 13d.
  • the grid 11 comprises two guide elements 14 and 15, which are also aligned parallel to each other and arranged on opposite sides.
  • the two rods or guide elements 14 and 15 are each arranged between the support region 12 and the outer lateral subelements 13c and 13d, respectively, viewed in the x direction.
