Definitions

  • the invention relates to a cooking oven, having a cavity which is closable by a door, wherein a fan element is arranged in or adjacent to the cavity by which air can be blown through the cavity and wherein a fan cover is arranged between the cavity and the fan element.
  • a cooking oven according to this kind is well known in the art. Reference is made to DE 699 19 268 T2 , DE 695 17 949 T2 , DE 692 14 960 T2 or EP 1 515 591 A1 , where cooking ovens are disclosed which are equipped with a fan element to guide hot air through the cavity.
  • the fan element is arranged e. g. at the rear side of the cavity.
  • a fan cover is employed.
  • the cover is equipped with a plurality of slits or holes through which air can flow.
  • an oven which has a fan cover consisting of two plates from sheet metal which are firmly arranged in the cavity of the oven.
  • the solution of this object according to the invention is characterized in that the fan cover consists of at least two parts, wherein one part of the fan cover is detachably arranged at or on another part of the fan cover.
  • the fan cover is made as a two-part element, wherein one part of the fan cover is detachably arranged at or on the other part of the fan cover, wherein the other part is firmly connected to the oven or to a wall of the cavity.
  • the surrounding edges of the at least two parts of the fan cover have preferably substantially the same size.
  • a further preferred embodiment of the invention suggests that the fan cover covers substantially the whole rear side of the cavity.
  • the first part of the fan cover is preferably designed to obtain a positive aesthetical appearance.
  • the first part of the fan cover can have a plurality of openings. Those openings can be equally distributed along the entire surface of the part.
  • a preferred embodiment of the first part of the fan cover has openings with a circular shape. Those openings (bores) can all have the same diameter.
  • the second part of the fan cover which is hidden by the first part during normal use of the oven is designed to obtain an optimized function with respect to fluid-mechanical aspects.
  • the other (second) part of the fan cover has a central opening.
  • This opening can have a circular shape.
  • the diameter of the opening can be substantial equal to the outer diameter of the fan element and the fan wheel respectively.
  • a preferred solution suggests that the two parts of the fan cover are kept at a predetermined distance when being mounted.
  • connection means can be a clip connection, by which the parts are detachably connected.
  • a further preferred embodiment employs parts of the fan cover which are made from sheet metal.
  • the production method of the part of the fan cover is well known and allows a cheap production of the different parts.
  • the plurality of openings in the first part as well as the big central opening in the second part can be produced by punching. By this process it becomes easily possible to machine quickly the plurality of holes into a sheet metal plate.
  • the first part of the fan cover can be detached from the second part of the fan cover which is firmly connected within the cavity.
  • the first part is exposed to the inner of the cavity and this takes the major part of dirt and fat during the use of the oven.
  • the detached first part of the fan cover can then be cleaned separately and outside the oven, e. g. it can be put into a dishwasher.
  • Another aspect is that is becomes possible to design the visual appearance of the fan cover just by designing the first part of the fan cover.
  • This part can be equipped with a plurality of slits or holes having a positive aesthetical appearance.
  • the second part of the fan cover can be designed only according to the function of the fan cover as the second part will be hidden by the first part during use of the oven.
  • a cooking oven 1 which has a cavity 2.
  • the cavity 2 is closable by a door 3 in a well known manner.
  • a fan element 4 is arranged in the rear area of the cavity 2, more specifically at the rear side 6 of the cavity 2 .
  • the fan element 4 has a fan wheel 10 which is driven by an electrical engine 11 in a well known manner.
  • a fan cover 5 is arranged between the cavity 2 and the fan element 4.
  • the fan cover 5 is designed as a two-part element, i. e. the cover 5 has a first part 5' and a second part 5". Both parts (the first part 5' is shown in FIG 2 , the second part 5" is shown in FIG 3 ) have substantial a plate-like form and a rectangular basic shape. The size of both parts 5', 5" is substantially the same. Both parts 5', 5" cover substantially completely the rear side 6 of the cavity 2.
  • the second part 5" of the fan cover 5 is firmly connected to the oven and the cavity 2 respectively, e. g. it is attached by means of screws.
  • the first part 5' of the fan cover 5 is detachably connected to the second part 5''.
  • a clip connection 9 is employed (shown only schematically). By this type of connection the first part 5' can easily be pushed on the second part 5'' for mounting the fan cover 5 or can be pulled from the second part 5'' for disassembling of the fan cover 5.
  • the clip connection between the parts 5' and 5" also makes sure that both plate-like parts 5', 5" are arranged parallel relatively to another with a distance a between them (see FIG 1 ).
  • the second part 5'' of the fan cover 5 is designed only with respect to the fluid-mechanical function of the fan cover 5, i. e. the design with respect to the aesthetical appearance is irrelevant.
  • the first part 5' is designed so that a positive aesthetical appearance is given.
  • FIG 2 and FIG 3 This can be seen in FIG 2 and FIG 3 . While the second part 5" of the fan cover 5 has a central opening 8 with a diameter substantially equal to the outer diameter of the fan wheel 10, the first part 5' is coming up with a plurality of openings 7 which are equally distributed across the whole surface of the first part 5' (only a number of openings 7 are shown in FIG 3 ).
  • a fan cover is can be made sure that the air flow of hot air discharged by the fan element 4 through the cavity 2 is optimized with respect of the fluid-mechanical aspects (achieved by the design of the second part 5'').
  • the aesthetical appearance of the fan cover 5 is also optimized by designing the first part 5' in a desired way.
  • the inventional concept is primarily used for domestic cookers but is not limited to this application. It can be used in all cooking ovens.
