Appeal No. 1998-0093 Application No. 08/459,301 enter and exit the oven. The reasons for such venting are as follows: Further features of the invention include venting of the cooking compartment to permit its end panels to remain cool with a shorter overall length than is required when the cooking compartment is not ventilated. This permits the end panels to be formed from wood which provides a pleasing aesthetic appearance of the cooking appliance. Venting the compartment also lowers the temperature of the air, the lamp glass and the support grid and thereby improves reliability by reducing the possibility of damage to the plastic pouch. [Col. 2, ll. 1-10.] Specifically, vent openings 60 "provide ventilation at the opposite ends of the cooking compartment to reduce the air temperature in the cooking compartment and to help prevent overheating of the wooden end walls 16 and 18 and the microswitch 50" (col. 3, ll. 38-42). Vent openings function as follows: Vent opening 61 provides ventilation of the space between wall 34 and the wooden end panel 16 and, therefore, cools the panel, the switch support wall 38, the microswitch and the lamp sockets. Vent opening 62 provides ventilation of the space between wall 36 and the wooden end panel 18 and, therefore, cools the panel and radiation shield 39 which is supported at its sides on wall 36. Vent 61 also permits the use of a microswitch 50 rated for low temperature operation as contrasted with the more expensive high temperature types. The switch is the most expensive single component in the oven; and a means for keeping it at lower temperatures is, - 9 -Page: Previous 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 NextLast modified: November 3, 2007
