Definitions

  • ABSTRACT A glass plate surface heating unit supported on a heat spreader plate that is combined with an underlying heating element and a heat reflector pan.
  • a trim ring surrounds the unit, and the ring has support means for fastening the unit components together.
  • the tim ring has a manually operable, top-serviceable spring locking means for fastening the heating unit in a supporting panel.
  • a standard electric cooktop for the kitchen is usually provided with a plurality of metal sheathed electrical resistance heating elements which are each wound in the form of a spiral coil and positioned in an opening formed in the cooktop. Each heating element is adapted to support a cooking utensil thereon. These metal sheathed heating elements are cleaned automatically of food soil due to thehigh temperatures they are allowed to reach once they are energized, but it is possible for spillovers to drain through the heating element and accumulate in a, collecting pan located beneath the cooktop from which they must be cleaned by hand.
  • the principal object of the present invention is to provide a solid plate surface heating unit with an improved mounting means for fastening the heating unit in place with a simple turning action thereby obtaining a tight spring holding force.
  • a further object of the present invention is to provide a solid plate surface heating unit with a trim ring provided with a spring locking means to bias the trim ring in a downward holding position.
  • a further object of the present invention is to provide a solid plate surface heating of the class described with a combined trim ring and spring means so as to exert a pull-down force on the trim ring to clamp the heating unit in a cooktop.
  • the present invention in accordance with one form thereof, relates to a solid plate surface heating unit that has a trim ring encircling the unit where the trim ring has a flat annular flange and a cylindrical vertical shank portion having support ledges on its inner surface that engage under the solid plate unit.
  • Spring locking means are associated with the lower portion of the trim ring and are adapted to engage beneath an adjacent surface of a heating unit supporting structure to bias the trim ring in a downward holding position.
  • FIG. 1 is a fragmentary cross-sectional elevational view of the left side of a flat plate surface heating unit embodying the present invention showing the nature of the trim ring encircling and supporting the unit and being provided with a spring locking means associated with the lower portion of the trim ring to bias the trim ring in a downward holding position.
  • FIG. 2 is a fragmentary side'elevational view taken on the line 22 of FIG. I with the cooktop removed so as to show the nature of the spring locking means of FIG. 1 and the method of connecting it to the trim ring by means of a removable bracket member.
  • FIG. 3 is a fragmentary cross-sectional elevational view through the left side of the surface unit, similar to that of FIG. 1, except it is taken at a diflerent diametrical line remote from the spring locking means to illustrate the manner of supporting the glass-ceramic plate and its underlying heat spreader plate and the lowermost heat reflector pan from the trim ring by means of lanced support ledges formed on the inner surface of the cylindrical shank portion of the trim ring, there being shown in addition an adjustable ring member compressed between the ledges of the trim ring and the peripheral edge of the reflector to create a tight clamping action.
  • FIG. 4 is an exploded view, on a somewhat smaller scale, of the components of the entire solid plate surface heating unit of the present invention showing the three-dimensional characteristic of the various components, and also the nature of the notches in the peripheral edge of the recessed opening in the cooktop in which the heating unit is to be mounted, where the notches are adapted to receive the spring locking means supported from the trim ring so that the entire unit may be turned and its spring means moved beneath the peripheral edge of the opening to exert a pull down force on the trim ring.
  • FIG. 1 there is shown a fragmentary cross-sectional elevational view of the left side of the flat plate surface heating unit 10 of the present invention.
  • a disk or plate 1 1 of glass-ceramic material that is a high temperature, high resistivity dielectric material that is preferably opaque and milkwhite in appearance.
  • This plate is supported on a thin heat spreader plate 13 of high thermal conductivity such as aluminum or stainless steel, or of composite plate material with an inner core of copper or the like and an outer skin of stainless steel or the like, where the peripheral edge of the composite plate is sealed by the stainless steel to prevent oxidation of the copper core at the high temperatures at which this member will be operated.
  • a metal sheathed electrical resistance heating element 15 Attached to' the underside of the heat spreader plate 13 is a metal sheathed electrical resistance heating element 15 that is formed in a flat spiral with several turns so as to cover as much of the surface of the spreader plate 13 as is possible so as to furnish generally uniform heat to the spreader plate and then to the glass-ceramic plate 11 for transfer to the bottom of the cooking utensil that would be seated directly on the glass ceramic plate 11.
  • a heat reflector pan 17 Positioned beneath the heating element 15 in a spaced relation is a heat reflector pan 17 that is of dished configuration with a large central depression 19 and a series of three annular steps around the periphery; namely, lower step 20, middle step 21, and finally upper peripheral step 22, which is adapted to bear against the underside of the peripheral edge of the glass plate 11, as is best seen in FIG. 1.
  • two holes 24 and 25 are formed in the reflector pan 17. These are adapted to receive the two terminal ends 15 of the heating element 15, which terminals are vertically arranged to extend down through the holes 24 and 25 for making an electrical connection with fewer lead wires (not shown) beneath the reflector pan.
  • the heat spreader plate 13 is provided with a downtumed flange 27 at its peripheral edge so as to reinforce the plate against buckling as well as to serve to support the plate 13 on the middle step 21 of the reflector pan 17.
  • the diameter of the heat spreader plate 13 is of such a size that its flange 27 bears against the riser 28 that connects the middle step 21 with the uppermost step 22.
  • a thin sheet of metal trim ring 30 is adapted to slip down over the glass plate 11 and reflector pan 17 with the heat spreader plate 13 and the heating element 15 seated therein so as to fill the air gap or clearance between the glass plate 11 and the peripheral edge 32 that surrounds the opening 34 in the cooktop 36.
  • the opening 34 is formed by a circular recess that has a bottom wall 38 which is provided with a large central opening 40 in which is centered the lower portion 19 of the heat reflector pan 17 as is best seen in FIG. 1. Because of the presence of the large central opening 40, the bottom wall 38 appears as a narrow ledge surrounding the opening 40.
  • the trim ring 30 has a generally I-shaped transverse elevational cross-section having a head portion 31 and a shank portion 33.
  • the head portion 31 has an inner edge 44 both overlying the peripheral edge of the glassceramic plate 11 and an outer edge 46 adapted to overlie the peripheral edge 32 of the cooktop 36. Notice that the head 31 of the trim ring 30 is inclined upwardly toward the center for the reason that the edge of the edge of the glass-ceramic plate 11 is leveled and rises slightly above the top surface of the cooktop 36.
  • the shank portion 33 of the trim ring is a generally cylindrical member of a rather shallow depth such that it does not reach the narrow ledge 38 in the recess 34 of the cooktop as is clear from FIG. 1.
  • the shank portion 33 of the trim ring is provided with a series of widely spaced support ledges 50 which are created by forming lancings 52 as is best seen in FIG. 3, where the peripheral edge of the top step 22 of the reflector pan 17 is adapted to rest upon support ledges 50.
  • the trim ring may be inverted and placed on a work bench. Then the glass plate 11 is slowly lowered into the trim ring thereby pressing tightly against the series of lancings 52.
  • annular spring means 51 of small gauge wire is installed to be sandwiched between the support ledges 50 and the underside of the peripheral flange or top step 22 of the reflector pan 17.
  • This annular spring member 51 is of circular shape in plan view, but in elevational view it has a sinesoidal shape such that it must be compressed in a vertical direction in order to confine it into position as best seen in FIG. 3.
  • the complete flat plate surface heating unit is assembled together except for the means for mounting the unit within the recessed opening 34 in the cooktop 36.
  • a mounting means is exemplified by the spring locking means 55 that is best seen in side view in FIG. 2. It is an endless strip of spring material that is formed in the general shape of an oval when viewed from the side, except that the top surface has sharper features of inverted V-shape with inclined sides 57 and 58 that join at the middle at apex 60.
  • This spring locking means 55 is fastened to a small sheet metal bracket 62 as by means of the rivet 64. The nature of the bracket can best be understood form FIGS. 1 and the exploded view of FIG. 4.
  • the bracket 62 has a channel shape that is arranged on its side by lower flange 65, a vertical base portion 66 and an upper flange 67. Notice that the spring 55 is fastened to the lower flange and that it extends from the lower flange 65 to the upper flange 67.
  • the top of this channel shaped formation of the bracket is provided with a vertical strap 69 for making a connection to the shank portion 33 of the trim ring 30.
  • the strap portion 69 is provided with two offset tabs 71 and 72 which are adapted with an angular motion to slip into mating slots 73 and 74 respectively, such that when the surface unit is lowered into the recess opening in the cooktop, the bracket member is in its vertical position as best seen in FIG. 1.
  • the narrow ledge 38 within the recess 34 of the cooktop is provided with two spaced notches 76. These are for receiving the two opposite brackets 62 which are adapted to slip down through the notches so that when a turning force is applied to the surface unit 10, the locking springs 55 will slip under the narrow ledge 38 thereby exerting a pull-down force on the trim ring and consequently on the surface unit, thereby locking the surface unit in place.
  • a flat plate surface heating unit comprising a recessed reflector pan and a flat substantially circular plate of high temperature, high resistivity dielectric material such as crystalline glass supported over the top portion of the reflector pan, a heat spreader plate of high thermal conductivity disposed against the underside of the crystalline glass plate, and a metal sheathed heating element attached to the underside of the heat spreader plate, and a trim ring encircling the unit and having a top flange with an inner edge overlapping the peripheral edge of the flat plate and an outer edge adapted to overlap an adjacent peripheral edge of a supporting structure, said trim ring also having a vertical shank portion with support ledges on its inner surface that engage under the peripheral edge of the reflector pan, and annular spring means associated with the said support ledges to clamp the unit within the trim ring, and spring locking means associated with the lower portion of the trim ring and adapted to engage an adjacent surface of a heating unit supporting structure to bias the trim ring in a downward holding position.
