International Classification:

F26B 330

US Classification:

392411

Abstract:

A module for use in a heating appliance has a frame with first, second, third, and fourth sides. A first heating lamp is mounted substantially along the first side of the frame, a second heating lamp is mounted substantially along the second side of the frame, a third heating lamp mounted substantially along the third side of the frame, and an fourth heating lamp is mounted substantially along the fourth side of the frame. Fifth, sixth, seventh, and eighth heating lamps are mounted substantially diagonally to the frame. A first reflector reflects radiant energy from the first heating lamp, a second reflector reflects radiant energy from the second heating lamp, a third reflector reflects radiant energy from the third heating lamp, and a fourth reflector reflects radiant energy from the fourth heating lamp. A fifth reflector reflects radiant energy from the fifth, sixth, seventh, and eighth heating lamps. The first, second, third, and fourth reflectors are generally parabolic reflectors, and the fifth reflector is a formed reflector.
