Definitions

  • ABSTRACT OF THE DISCLOSURE A door for a high temperature oven where there is a transparent window in the door and a manually movable shutter located within the door Iso that in one position the shutter "closes the window and in a second position it is retracted into the door structure.
  • the shutter is supported and guided by a track which cooperates with slide members on the Ishutter so as to permit freedom of movement of the shutter on the track under high temper-ature conditions.
  • Housewives have become accustomed to the convenience of a window in their oven door so that they may observe the food while it is being cooked. This avoids the necessity of opening the oven door in order to judge the degree of doneness of the food.
  • housewives have been given the opportunity of owning a self-cleaning oven that operates on the princple of pyrolysis for decomposing the food soil and grease spatter that accumulate on the oven w-alls during normal cooking operations.
  • Such a self-cleaning oven is taught in the patent to Bohdan Hurko No. 3,121,158, which is likewise assigned to the assignee of this invention.
  • Such self-cleaning ovens operate lat a high temperature range above the normal cooking tem-perature range of between 150 F. to 550 F.
  • the conventional oven door windows were not capable of confining the increased amount of heat energy to the oven cavity, and hence they were omitted in the early models of selfcleaning ovens in order to take full advantage of the selfcleaning oven features.
  • the 'above-cited Baughman et al. Patent 3,311,106 teaches the use of a movable shutter built into the door structure so that in one position the shutter blocks the window and serves as both a thermal radiation barrier and a visual barrier during the high temperature operation. During normal cooking operations this shutter would be retracted into the door structure so that the window would provide the convenience of the oven door Windows in standard ovens.
  • the shutter of the present invention is designed, according to a principal object thereof, so that thermal expansion will not allow it to distort and become jammed.
  • the present invention in accordance with one form thereof, relates to a door construction for a high temperature oven where the door includes a window opening that is closed with a plurality of transparent panes that are sealed -along their periphery to t-he door structure.
  • a manually movable shutter is located within the door and in one position the shutter blocks the window opening and in a second position it is retracted into the door 3,396,717.
  • FIGURE 1 is a perspective view of a free-standing domestic ran-ge having a windowed oven door embodying the present invention.
  • FIGURE 2 is a cross-sectional, elevational view on an enlarged scale looking from the right side of the oven door of FIGURE 1 to show the movable shutter located in its raised position, as well as the nature of the rails on Iwhich the shutter is supported and guided. This view is taken on the line 2-2 of FIGURE 3.
  • FIGURE 3 is a fragmentary, cross-sectional, plan view adjacent the right top corner of the oven door taken on the line 3-3 of FIGURE 2.
  • FIGURE 4 is a fragmentary, elevational View of the innermost portion of the door taken on the line 4-4 of FIGURE 3 rwith the front door panel, part of the insulation and other small element-s so as to be able to see the shutter in the raised positions and the nature of its cooperation with one of the rails of the track system of the present invention.
  • FIGURE 5 is a perspective view of an enlarged scale of one of the slide members which are fastened to the shutter at the extremities thereof for engagement with the rail of the track system.
  • FIGURE 6 is a fragmentary, cross-sectional plan view of an oven door latching mechanism for locking the oven door in the closed position during the high temperature operation.
  • FIGURE 1 there is shown -for illustrative purposes a free-standing electric range 10 having a top cooking surface 11 with a plurality of surface heating elements 12, a baking oven 13 formed by a box-like oven liner 14 and a front-opening, drop-door 15. While the oven door of the present invention is shown as being installed on an electric oven it Will be readily apparent to those skilled in this art that the invention is not limited to use with an electric oven. It may be used just as well with an oven heated by gas or perhaps other energy sources. It could falso be used with a built-in oven or in f fact any type of high temperature cavity.
  • the Oven cavity is supplied with two standard heating elements; namely, a lower baking element 16 and an upper broiling element 17 located adjacent the top w-all of the oven liner.

  • the heating elements land their control switches and oven timer will be arranged and operated as described in the aforementioned Hurko patent to provide the normal cooking 3 operations ias well as the high temperature oven cleaning operations.
  • a pull-out drawer 23 Positioned beneath the oven 13 is a pull-out drawer 23 which is a storage drawer for cooking utensils and the like. However, in a gas oven this space is usually allotted to a separate broiler compartment.
  • the oven door is of generally sheet metal fabricated construction having three main elements; an outer, decorative door panel 25, an inner door liner 26 and a floating inner panel 27 supported from the inner door liner 26.
  • the outer door panel 25 is of shallow-pan shape by virtue of the fact that it has a slight, rearwardly-turned peripheral ange 29.
  • the inner door liner is also of shallow-pan shape, and is it of mating construction with the outer' door panel 25 by virtue of the fact that it has a front-turned peripheral flange which telescopes within the ange 29 of the outer door panel 25.
  • the inner door liner 26 includes a generally rectangular, central, outward embossrnent 32 of such a size as to iit closely within the front opening of the oven frame, as is best seen in FIGURE 3.
  • the floating door panel 27 is likewise of shallow-pan shape having a front-turned peripheral liange 34, and it covers an area that is slightly less than the area of the outward embossment 32 of the inner door liner 26.

  • the present invention relates to a high temperature transparent window 45 formed in the oven door 15 and used by the housewife for viewing the food while it is being cooked in the oven.
  • This window is so constructed that it is protected by means of a shutter which serves both as a radiation barrier and a visual barrier during a high temperature operation.
  • the door also has an interlocking means with an oven door latching system so as to preclude the operation of the high temperature cycle unless the oven window is first protected by the movable shutter as will be better understood hereinafter.
  • a window opening is formed in each of the three door elements; namely, the outer door panel 25, the inner door liner 26, and the iioating inner panel 27.
  • it is well to provide for the sealing of the window so as to prevent the escape of odors, vapors as well as convection currents of hot air. It is particularly important to prevent the condensation of oven vapors on the inner surfaces of the glass panes which would otherwise tend to soil the glass and obscure viewing into the oven cavity.
  • FIGURE 3 there are three glass panes 51, 52 and 53.
  • the two frontmost panes 51 and 52 are separated by a continuous spacer frame' 54 and they are held together by an outer frame 55 of U-shaped transverse cross-section which slips around the periphery of the two panes to form a sealed glazing unit 58.
  • a decorative trim frame 57 of acute angular shape in transverse cross-section extends around the periphery of the front edge of the outermost glass pane 51, and it is likewise held in place by the outer frame 55.
  • This glazing unit sub-assembly 58 is shown as being fastened to the back side of the outer door panel 25 by means of support flanges 58 and 59, as is best seen in FIGURE 2.
  • the third glass pane 53 is shown in FIGURE 2 as being fastened over the window opening 48 in the inner door liner 26 from the inner side thereof by means of fastening screws 36 and clip members 61. Moreover, there is a decorative trim frame 64 assembled around the peripheral edge of the glass sheet 53 so as to mask the peripheral edge of the glass sheet from view. This trim frame 64 telescopes into the window opening 49 of the iioating inner panel 27. A suitable sealing gasket 62 is sandwiched between the glass pane 53 and the trim frame 64, again to seal the glass against the escape of gases and vapors around the edges thereof.
  • thermal insulation 66 of iiberglass or the like material substantially fills the inner panel 27,
  • a second layer of insulation 67 is located between the outer door panel 25 and the inner panel 26, but it does not completely lill this cavity.
  • Suitable air inlet openings 72 are formed in the bottom edge of the door to permit room air to rise through the air chamber 69.
  • the top edge of the door is provided with suitable air outlet openings 74, which are best shown in FIGURE 1.
  • a second insulation guard 76 is mounted against the layer of insulation 67 so as to confine this layer between the two insulation guards 70 and 76.
  • This chamber 78 is formed between the second insulation guard 76 and the inner surface of the embossment 32 of the inner door liner 26.
  • This chamber 78 extends upwardly between the second yand third glass panes 52 and 53.
  • the purpose of this chamber 78 is to accommodate a reiiective shield or shutter 80 which is shown in the raised position in FIG- URE 2 but which is capable of being retracted into the lower portion of the door so as to be completely out of view so as to enable the housewife to see into the oven cavity 13.
  • This shutter 80 is of generally rectangular configuration and formed of aluminum sheet metal which tends to expand and contract depending upon its operating temperature but especially during a heat cleaning operation.
  • the temperature of the innermost transparent pane 53 during a heat cleaning operation might be as high as 900 F., and the temeprature of the shutter 80 might be as high as 650 F., while the temperature of the outer 233e' l might be somewhere between 200 F. and
  • the present invention contemplates the use of a track system on which the shutter 80 is capable of sliding action.
  • This track system includes a pair of vertical rails 82, 82 of generally Z-shape in transverse cross-sectional view, as is Ibest seen in FIGURE 3.
  • Each rail 82 is positioned inboard of ythe related vertical side of the shutter 80.
  • the rail 82 has a head 83 and an L-shaped base with flanges 84 land 85 respectively.
  • the flange 85 is adapted to be connected by means of welds or suitable fastening means (not shown) to the inner surface of the embossment 32 of the inner door liner 26.
  • each side of the shutter 80l and the related rail 82 is identical for both sides, only the right side of the shutter is shown, and that is in FIGURES 3 and 4.
  • Adjacent the upper and lower extremity of each vertical side of the shutter 80 is fastened a slide member 86 as is best seen in FIGURE 4, and its configuration can best be understood from the :perspective view of FIG- -URE 5.
  • -Each slide member 86 is a block-like form that has an arcuate surface 88 that is adapted to cooperate with the ange 84 of t'he base of the rail 82.
  • each slide member 86 there is a slot 89 formed in each slide member 86, and this slot lies in -a plane that is perpendicular to the longitudinal laxis of the arcuate sur-face 88.
  • This slot 89 is adapted to receive the head 83 of the rail 82 4as is best seen in FIGURE 3.
  • the slide member l also contains a through opening 90 for receiving a fastening screw 91 therethrough as is best seen in FIGURE 3 so that the slide member may be attached to the side edge of the shutter 80 and serve as the supporting means between the shutter y80 and the rail 82.
  • the preferred embodiment of the slide member 86 is formed of a non-metallic material that is impregnated with graphite and is sold under the trade name Graphitar that is sold by the U.S. Graphite Company of Saginaw, Michigan. Such a material as a characteristic lubricity which is not elected by high temperatures in the vicinity of 900 F. in that it does not lose its low friction characteristic.
  • This cooperation between the four slide members 86 and the two rails 82 of the track system gives positive location of the shutter and prevents any jamming action that might be caused by thermal expansion of the shutter.
  • any expansion of the shutter tends to move the slide member 86 in a direction away from the rail head 83 and base flange 84 so that the shutter is not prevented from expanding, but instead is permitted to expand without altering the positive location of the shutter within the door assembly.
  • the upper corners of the shutter 80 are each provided with an outward, side extension 95 which extends through an elongated slot 96 in the side of the embossment 32 of the door to ⁇ form a handhold 97 so that the housewife may grasp the handhold on each side of the embossment and raise or lower the shutter as is desired.
