  • Publication number: 20140238969
    Abstract: A system for support and securement of a thermal heating panel of a carousel oven upper a rotational axle includes a flat upper receiver formed of several diametric strips. The upper receiver is proportioned for complemental receipt of the heating panel. At, or integrally secured to, the bottom of the upper receiver, and situated polarly symmetrically about the axle, is a cradle proportioned for complemental fit upon a male drive shaft at an uppermost end of the axle. Due to the weight of the heating panel and its slow rate of rotation within the carousel oven, the force of gravity of the heating panel is sufficient to maintain the upper receiver and its cradle upon the male drive plate even in the absence of positive securement between the elements. Alternatively, the heating panel is entirely replaced by a grill-like surface, secured above or below the diametric strips to permit the grilling of types of meat or food other than those typically cooked upon the thermal plate panel.

  • Patent number: 7342203
    Abstract: In one example, an oven chamber has a heating element located within a first section of the oven chamber, and includes a shielding member that extends over the first section of the oven. The shielding member has an outer boundary, and one or more portions of the outer boundary are spaced away from walls of the oven chamber so as to form an open space through which convective heat is able to pass. The shielding member is supported above the heating element by support elements on which the shielding member rests and a portion of the outer boundary of the shielding member that extends away from the remainder of the shielding member to the bottom wall of the oven chamber, and the latter portion of the outer boundary of the shielding member attaches to a bracket fastened to the bottom wall of the oven chamber.
