This is formed from the described materials of the fastener, and serves to accommodate the loads and for positioning of the fastener in the housing of the cooking appliance.
  • At least one end of the first lattice strut is designed for attachment to a housing component in the interior of the household appliance.
  • the ends of the first lattice strut are bent in such a way that they, preferably resiliently, make contact with housing components.
  • the ends are designed so that no further fastening elements, such. As screws, needed to secure the fastener in the cooking appliance.
  • two such first grid struts are arranged mirror-symmetrically to each other and form the base of the fastener. In this case, the angularly projecting ends of the lattice struts preferably have outwards.
  • the fastening element preferably has at least one second lattice strut.
  • This lattice strut which is arranged essentially transversely to the front of the device, connects the first lattice struts to one another and thus spans the substantially planar and rectangular shape of the attachment element.
  • the second grid strut has at least one holding element.
  • a holding element is to be understood in particular a receptacle which serves for the storage of the cooking chamber.
  • the ends of the second lattice strut are bent and shaped in such a way that they can engage in corresponding fastening means of the cooking chamber.
  • these corresponding fastening means of the cooking chamber are formed as tabs which protrude from the cooking chamber.
  • two such second lattice struts are arranged mirror-symmetrically to one another on the fastening element.
  • the fastening element has at least one transverse strut.
  • a cross strut should in particular be understood to mean an element of the fastener element, which is formed from a wire element described above and preferably parallel to the second grid struts and is preferably attached to the first grid struts.
  • the original task of the fastening element to fix the insulating body to a sufficient extent relative to the cooking chamber is supported by one or more transverse bars, which in particular prevent the sagging of the insulating body.
  • the grid struts and the existing transverse bars are joined together by means of a welding process. If the components of the fastening element are fastened to one another by means of a welding method, a particularly simple and cost-effective design of the fastening element can be achieved.
  • the at least one transverse strut preferably has sections which are designed to hold and / or fasten an insulating body in the region of the cooking chamber bottom or the cooking chamber side walls.
  • the sections may be upwardly bent ends of the transverse struts which fix the insulation body lying on the fastening element.
  • the sections, in particular a fastening element arranged in the base region can be designed to be very long so that they hold and secure the insulation bodies which cover the side wall of the cooking chamber, as a result of which separate intermediate walls can be saved.
  • the fastening element preferably secures the insulation bodies to the underside of the cooking chamber.
  • the cooking chamber is provided on the floor and ceiling surfaces, on the side walls and on the rear wall with an insulating body.
  • the insulating body which is assigned to the bottom surface, is particularly prone to sag.
  • the fastening element counteracts the sagging of the insulating body on the underside of the cooking chamber.
  • the fastening element secures the insulating body to the side and / or rear wall of the cooking chamber.
  • further fastening elements in the manner described above, can be attached to fix the insulating body on the side and / or rear wall.
