Definitions

  • the invention relates to an oven with a cavity delimiting a cooking chamber and particularly, an oven that is disposed in a cabinet and having a gap between the cavity to reduce the heat transfer.
  • a cooking chamber is delimited by a heat-insulated metal cavity.
  • the metal cavity generally performs the cooking process with the help of the electrical heating element provided under the floor and in the top section.
  • the cavity reaches high temperatures and expands with the effect of this, making an outward curve. Measures are taken to reduce the effect of high temperature in the cavity to affect the surrounding parts.
  • a solution is to provide a side panel that extends at a distance from the lateral wall of the cavity and defining a corridor. The side panel is inserted in a cabinet that is fixed to the outer casing of the oven, forming a suitable slot.
  • US4848311A discloses the temperature of localized high temperature regions in the side panels of a kitchen range is reduced by the use of thermal conduction breaks to interrupt thermal conduction paths and inhibit the transfer of heat from the oven through a supporting frame to the side panels.
  • the thermal conduction breaks comprise a plurality of thin, vertically orientated elongated slits in upper portions of the front faces of the side panels. Heat transfer into the side panels due to radiation from the oven door is reduced by forming the oven door with a plurality of elongated slits disposed about a central portion of the door which closes the oven access opening to interrupt thermal conduction paths from the central portion to peripheral regions of the door adjacent to front faces of the side panels.
  • an oven is comprising muffle having a lower wall, an upper wall spaced parallel to the lower wall and opposing lateral walls parallel to each other extending therebetween confining a cooking chamber; a side panel disposed parallel to the lateral wall at a distance from interior section mounted to the muffle such that delimiting a gap therebetween, and a frame extending from an outer periphery of an opening of the muffle.
  • the oven further comprises a mounting tab formed by bending inward from a peripheral edge of the frame such that abutting the side panel and a fastening element is provided between the mounting tab and the corresponding side panel in a manner that directly attach the mounting tab to the side panel. Fixing the side panel directly to the mounting tab helps the side panel to securely maintain the gap between the side panel and the cavity.
  • the fastening element may include screws or similar fastening elements, or it may be provided in the form of interlocking corresponding slot and plug.
  • an inner flap that bends from a front edge of the side panel to jointly form U cross-section and support the corresponding mounting tab from end-to-end.
  • the inner flap reduces heat transfer from the frame to the side panel by providing a butt surface that is removed from the other part of the side panel for mounting with the mounting tab.
  • the attachment extension may also be mounted directly to the side panel in a one-piece sheet construction from the inside or external side of the side panel.
  • a preferred embodiment comprises a hole is provided on both the inner flap and the mounting tab in a mutually aligned manner and through which a screw of the fastening element extends in a securing manner.
  • the hole allows simply to fix the inner flap and the mounting tab by means of a screw.
  • a through opening with a larger diameter than the hole is provided in line with the hole on the side panel.
  • the opening allows access to the hole from the external side of the side panel. In this way, fastening of the inner flap and the mounting tab can be done by accessing through the opening.
  • a cover that fits into the opening.
  • the cover close the opening and prevents access into the cavity from the side panel.
  • the cover is convex extending outward on an external part of the side panel.
  • bulges out from the side panel and when the housing is disposed inside a cabinet contacts the cover instead of the external face of the side panel, forming a gap between the outer part of the side panel and the outer part, reducing the heat transfer.
  • an emboss with the same height with the cover is extending outwardly from the external part close to a rear edge of the side panel opposite the front edge.
  • the emboss forms a support with the front cover and prevents the side panel contact of the cabinet from side to side.
  • the cover and the emboss are aligned in line transversely.
  • the cover and the emboss provide a support against thermal stresses, preventing deflection along the imaginary axis between them.
  • the side panel and frame are made of one-piece metal sheet.
  • the mounting tab can be cold formed by bending.
  • sufficient resistance is provided against the high temperature transmitted from the cavity during cooking process without deteriorating the structural integrity in the oven.
  • the fastening element is provided close to the upper edge of the side panel and having an auxiliary fastening element in the same form provided close to an opposite lower edge. In this case, it is possible for the side panel to resist agaist both the top and bottom thermal stresses by sharing.
  • the mounting tab is having an elbow section orthogonally bent across the peripheral edge of the frame facing the side panel towards the cavity.
  • Figure 1 is a partial top perspective view of a representative embodiment of an oven before mounting the side panel.
  • Figure 2 is a top view of the side panel aligned with the frame and cavity in the oven prior to the assembly.
  • Figure 3 is the top view of the oven shown in Figure 2 inside the cabinet with the side panel mounted.
  • Figure 4 is an enlarged schematic illustration showing the frame connection of a representative embodiment of the oven of the invention.
  • FIG 1 is a perspective view of a representative embodiment of a household oven with a side panel (20) adjacent to a muffle (10) in a disassembled position.
  • the muffle (10) has a rectangular opening (12) through which a cooking chamber is accessed.
  • the opening (12) is defined by front edges of two opposite side walls (18) of metal panel, a lower wall (14) extending at their lower end, and an opposite upper wall (16).
  • a metal sheet frame (30) extending outward from the muffle (10) is secured to the opening (12) in the form of a flange.
  • the frame (30) is obtained by cutting a flat sheet metal plate through its center to provide an hole that fits into the opening (12) and bending inwardly vertical L-shape along a peripheral edge (32).
  • the upper part of the peripheral edge (32) forms an upper lug (36) on which a support structure holding the control panel (not shown) will be disposed.
  • the part extending into the cavity (1 ) forms a mounting tab (34).
  • the mounting tab (34) extends vertically along the side edge of the frame (30).
  • a hole (37) is drilled in the upper and lower parts of the mounting tab (34) adjacent to the opposite corners.
  • a side panel (20) formed from metal sheet is fixed to the oven housing (not shown) adjacent to the corresponding side wall (18) with a gap (1) between them.
  • the side panel (20) and the side wall (18) are in a parallel position to each other.
  • the peripheral edges of the side panel (20) are bent inward perpendicularly.
  • On a flat outer portion (22) of the side panel (20) an opening (21) at the top and an auxiliary opening (23) at the bottom are provided, respectively, adjacent to a front edge (24) corresponding to the holes (37).
  • a emboss (26) is formed so that the opening (21) and the auxiliary opening (23) are on the same axis in the transverse direction.
  • the emboss (26) is in the same diameter as the opening (21) and is in the form of a dome.
  • the side panel (20) is mounted directly to the mounting tab (34) by inserting a corresponding fastener (50) and auxiliary connector (60) in each opening (21 , 23), respectively.
