Abstract

Heating apparatus comprising at least one heating element for radiating heat to a material to be heated, bracket means for supporting the heating elements, the bracket means comprising a sufficiently large opening in the side thereof away from the material to be heated so that the amount of deformation of the bracket means is minimal upon heating by the heating element, the ratio of the area of the opening to the area of the side being 60-80 percent, a plate disposed over the opening and adjacent the heating element for reflecting radiant heat from the heating element to expedite the heating of the material to be heated and to lessen the amount of power consumed by the heating element, and means for loosely connecting the plate to the bracket means so that, upon heating by the heating element, the plate deforms independently of the bracket in spite of it being disposed adjacent the heating element.

Claims

1. Heating apparatus comprising;

at least one heating element for radiating heat to a material to be heated;

bracket means for supporting said heating element, said bracket means comprising a sufficiently large opening in the side thereof away from said material to be heated so that the amount of deformation of said bracket means is minimal upon heating by said heating element, the ratio of the area of said opening to the area of said side being 60-80 percent;

a plate disposed over said opening and adjacent said heating element for reflecting radiant heat from said heating element to expedite the heating of said material to be heated and to lessen the amount of power consumed by said heating element; and

means for loosely connecting said plate to said bracket means so that, upon heating by said heating element, said plate deforms independently of said bracket in spite of it being disposed adjacent the heating element.

2. Heating apparatus as in claim 1 where said ratio is approximately 70 percent.

3. Heating apparatus as in claim 1 where said material to be heated is copying paper for use in a copying machine.

4. Heating apparatus as in claim 1 where said heating element comprises a longitudinally extending element having a V-shaped cross section with the top of the V facing toward said heat reflecting plate and with the bottom portion of one of the sides of the V blackened to generate heat.

5. Heating apparatus as in claim 4 where said bracket means includes at least two vertically extending side members and where said apparatus includes at least one support member extending longitudinally between said side members for supporting said heating element.

6. Heating apparatus as in claim 1 where said heat reflecting plate has a plurality of holes of a first diameter and where said conneCting means includes a plurality of members connected to said bracket of a second diameter less than said first diameter, said members being disposed in said holes to effect said loose connection of the heat reflecting plate to the bracket means.

7. Heating apparatus as in claim 6 where said members connected to said bracket comprise a plurality of spacers respectively disposed about a plurality of bolts respectively connected through a plurality of holes disposed about said opening in said bracket means.
