L'élément de production de chaleur (2a-2d) comprend un tube de production de chaleur (3) et un réflecteur (4). Le tube de production de chaleur (3) est un tube à rayonnement de chaleur dans lequel les rayons du tube de production de chaleur (3) qui irradient directement une partie centrale du gril (6) sont plus faibles que ceux qui irradient directement une partie externe du gril (6). Des rayons parallèles réfléchis produits par le tube de production de chaleur (3) projetés sur le réflecteur (4) irradient la partie centrale du gril (6), de telle sorte que la partie centrale et la partie externe du gril (6) sont chauffées uniformément. Le four de cuisson électrique de type à rayonnement présente un effet de cuisson équivalent ou meilleur que ceux des fours de cuisson électriques classiques, ne produit pas de fumées, et est très facile à nettoyer.
