Definitions

  • the invention relates to a muffle for a cooking appliance, such as an oven or a steam cooker or the like.
  • a muffle for an oven which is made up of several separate parts that are joined together.
  • a separate rear wall of the muffle is connected via rivets or screws with other walls of the muffle.
  • These further walls are each formed as an upper and a lower cover, which comprise in each case on opposite sides of a horizontally extending cover partial elements of a side wall.
  • the upper cover and the lower cover is formed in each case U-shaped.
  • a muffle is known, are formed in the plate-like side walls and a plate-like rear wall.
  • a separate ceiling and a separate floor are provided, which are connected to said components.
  • the side walls each have at their upper and at its lower edge outwardly angled flanges.
  • enameled oven muffles embodiments are known in which elements such as a ceiling, a floor muffle front and side walls and a rear wall are welded together. This is provided, for example, in muffles whose cooking appliances are designed with a pyrolysis function. The implementation of the pyrolysis function is associated with considerable costs. Changeover times when enamelling due to the muffle height are relatively large. In this regard, niche dimensions are known with 290 mm. With regard to ease of cleaning is known in such muffles that they are formed with catalytically coated sheets, such as a catalytically coated cover and a catalytically coated baffle.
  • a muffle according to the invention for a cooking appliance comprises a frame-like muffle front, in which a feed opening is formed. Furthermore, the muffle comprises two side walls which are connected to the muffle front, wherein at least one side wall has at least one connecting element, which is a member for creating a releasable connection between the side wall and a cover of the muffle.
  • the muffle can be expanded in its modular construction in that specific connections are provided, which are provided in particular between a side wall and a cover. The components muffle front, side wall and cover can thus be combined and modified in a variable and flexible manner, resulting in a high flexibility with regard to the muffle composition and a high degree of variability.
  • the muffle comprises an upper and a lower cover, which are each formed in particular plate-like.
  • the covers are separate elements.
  • the side walls are in a first approximation plate-like and thus preferably also flat.
  • the at least one connecting element is formed on an edge of a side wall.
  • the simple and fast connection with a cover can be made particularly advantageous.
  • a space-saving design can be formed.
  • a flange is formed on an edge of a side wall, on which the connecting element is formed.
  • the flange is formed substantially over the entire length of a side wall.
  • the side wall is plate-like and thus preferably formed in particular flat and the flange is arranged angled relative to this plane or the plate-like part.
  • the flange is bent substantially at 90 ° relative to the side wall, in particular outwardly with respect to the arrangement and design of the cooking chamber is arranged through the muffle walls.
  • At least one connecting element is formed on at least one side wall, in particular on two opposite side walls, on an upper edge and a lower edge.
  • both an upper cover and thus a ceiling, as well as a lower cover and thus a bottom, are connected by a detachable connection with the at least one side wall.
  • the highly flexible and variably modular module concept is further enhanced.
  • each side wall has at its upper and at its lower edge in each case a flange on which in each case at least one connecting element, preferably in each case two connecting elements are arranged.
  • the connecting elements extend substantially in the same plane as the flanges on the side walls. Again, thus a very space-minimized and thus flat design can be realized.
  • a connecting element is a tab with a passage for a screw for creating a screw connection between a side wall and a cover.
  • the detachable connection between a side wall and a cover is thus designed as a screw connection.
  • a releasable connection is understood to be one which can be separated and reassembled non-destructively. This may for example also be a latching connection or a clip connection or the like.
  • insoluble compound insoluble compound is understood as such, which can not be separated and non-destructively separated.
  • this welds, adhesive joints, rivets and the like may be mentioned.
  • the connecting element is a bracing element for generating a bracing connection between a side wall and a cover.
  • this is a detachable connection in the context of the present invention.
  • a cover and / or their material composition can thus be realized either a screw or a clamping connection.
  • the connecting element either contributes to the generation of a screw connection or is formed, or is formed as an alternative to generating a Verspanntagen.
  • a connecting element is designed to be multifunctional and thus enables both the generation of a screw connection and the generation of a bracing connection at the same time.
  • a connecting element is designed and constructed and arranged so that it offers the possibility to produce a screw connection or to produce a bracing connection.
  • a permanent connection is formed, which is understood as a permanent connection such as has already been stated above.
  • the basic structure of the muffle namely the muffle front and the side walls are mechanically stable connected and such an intermediate module is pre-assembled and manufactured and already provided for further processing of the muffle.
  • the muffle front and the side walls can be used in a large variety of different muffles as equal parts, thereby the manufacturing process can be accelerated and these intermediate modules are already prefabricated. Due to the non-detachable connection, in particular a welded joint, the corresponding requirements can be borne straight between these parts.
  • the muffle front has flanges which are permanently connected to the sides.
  • the flanges of the muffle front are formed on the vertical inner edges of the boundary of the feed opening of the muffle front. There, they are thus space-saving and not disturbing arranged for other components and allow a particularly area-covering connection with the side walls.
  • the side walls are integrally connected to a rear wall of the muffle.
  • the two opposing side walls and the back wall form a part which, in particular when viewed from above or from below, has a U-shape.
  • a seal is arranged between a side wall and a cover.
  • a glass-fiber direction of the seal is included, in particular, the seal is such a glass-fiber direction.
  • an advantage can be achieved in that the enamel material that has the cover can not chip off in an undesired manner.
  • the side walls are formed substantially plate-like. This applies in particular to a consideration in which the side walls are formed without the flanges and the connecting elements, in particular their respective orientation in comparison to the remaining part of the side walls.
  • the side walls are substantially vertical.
  • At least one cover of the muffle is at least partially formed of glass ceramic material.
  • heating elements of the cooking appliance positioned behind can be attached. All surfaces can be easily cleaned by hand, for example.
  • the heating elements may be formed, for example, as Wandsammlungleiter, which are mounted directly on the outside of a glass ceramic cover.
  • the connecting element for generating a Verspanntress between a side wall and the cover is formed.
  • An undesirable damage to the glass ceramic can be prevented.
  • At least one cover is at least partially made of a metallic material, which is at least partially provided with an enamel layer.
  • a cover is at least partially formed as a sheet, which is enamelled.
  • a connecting element is formed on a side wall for producing a screw connection between a side wall and such a cover.
  • At least one cover is at least partially catalytically coated.
  • a catalytically coated sheet can be provided.
  • a connecting element is preferably designed to produce a screw connection between a side wall and such a cover.
  • At least one cover is at least partially formed as a reflector for reflecting heat radiation and / or microwave radiation.
  • the connecting element is designed as such, which allows a screw connection between a side wall and such a cover.
  • a corresponding material design of the cover or a corresponding coating may be provided on a base material.
  • a cover which is also designed as a reflector, thus also has a multi-functionality.
  • the integration of such a reflector in the cover thus also allows material savings and space savings.
  • muffle just enamelling Due to the specific modularity of the muffle just enamelling can be done easily because the covers can also be retrofitted by the detachable connection only. Especially in niches this is very advantageous in terms of accessibility.
  • muffles which are completely welded, a reduction in costs are made possible because no full welding line is required, but only the muffle front with the side walls is preferably welded.
  • a muffle 1 with some sub-components is shown in perspective.
  • the muffle 1 is suitable for a cooking appliance, such as an oven or a steam cooker. Through the muffle 1 a cooking space is limited, can be prepared in the food.
  • the muffle 1 is in Fig. 1 shown with an intermediate module 2, which has a frame arranged on the front side as a muffle front 3.
  • the muffle front 3 is formed as a completely encircling square frame, which has a feed opening 4, through which front food can be introduced into the muffle 1 and thus also the cooking chamber of the cooking appliance.
  • a door is formed by means of which the charging opening 4 can be closed.
  • the muffle front 3 has at an inner edge 5, which limits the feed opening 4, on their vertical frame parts 6 and 7 bent backwards and also vertically oriented flanges 8 and 9.
  • Side walls 10 and 11 of the muffle 1 are welded to these flanges 8 and 9 and thus form a permanent connection.
  • the side walls 10 and 11 are formed on opposite sides and oriented in the vertical direction (y-direction).
  • the two side walls 10 and 11 are integrally formed with a rear wall 12 of the muffle 1.
  • a rear wall 12 of the muffle 1 When viewed from below (Positive y-direction) or from above thus form the side walls 10 and 11 and the rear wall 12 is a U-shaped part.
  • the side wall 10 has at its upper edge 13 on a flange 14 which is opposite to the plate-like central part of the side wall 10 substantially at right angles to the outside and thus turned away from the cooking chamber.
  • a correspondingly oriented flange 16 is likewise formed on a lower edge 15 of the side wall 10.
  • connecting elements 17 and 18 are formed, each having a passage 19 and 20 through which screws for creating a screw connection between the side wall 10 and a in Fig. 1 Not shown cover can be formed.
  • the connecting elements 17 and 18 are formed as tabs, which extend substantially in the same plane as the flange 14 and oriented outwardly therefrom.
  • 16 connecting elements 21 and 22 are formed on the lower flange, which correspond to the connecting elements 17 and 18 in shape and design. Again, each connecting element has a passage 23 and 24 for carrying out screws.
  • the flanges 14 and 15 and the connecting elements 17, 18, 21, 22 formed thereon are integrally formed with the side wall 10 and produced in a corresponding transformation process.
  • the side wall 11 is provided at its upper edge 25 with a flange 26, on which also two connecting elements 27 and 28 are formed with no further marked here passages. The same is provided on a lower edge 29 of the side wall 11, wherein here also a corresponding flange 30 is formed with not shown in detail and marked connecting elements for generating screw and / or Verspanntagenen, as may be provided in the other connecting elements.
  • the connecting elements 17, 18, 21, 22, 27 and 28 and the connecting elements formed on the lower flange 30 are all for generating a releasable connection between the side walls 10 and 11 and a in Fig. 1 not shown upper cover and a lower cover formed.
  • All elements can be designed both for producing a screw connection and / or a bracing connection.
  • a flange 32 is formed and at a lower edge, a flange 33 is formed.
  • an upwardly oriented webs 34 and a downwardly oriented web 35 are integrally formed on these flanges 32 and 33, which are formed to hold a cover top and bottom. A positional shift of the cover can be avoided and in particular the webs 34 and 35 are also provided for bracing the covers.
  • Fig. 2 the muffle 1 is shown with further components, in addition to the embodiment in Fig. 1 an upper cover 36 and a lower cover 37 are shown.
  • the top cover 36 has bushings 38, 39, 40 and 41 for passing screws for producing the screw connection with the side walls 10 and 11.
  • the lower cover 37 which bushings 42, 43, 44 and 45, through which also screws can be passed, in order to create a screw connection between the lower cover 37 and the side walls 10 and 11 can.
