Cooking apparatus equipped with heaters and method of controlling the same
First Claim
1. A cooking apparatus having two or more heaters installed in a first position of a cooking cavity to heat food, and a crumb tray insertable in a second position in the cooking cavity and used to contain the food in cooking modes using the two or more heaters, comprising:
- a temperature detection unit provided between the first and second positions to detect an inside temperature of the cooking cavity; and
a control unit to determine that the crumb tray is used when a temperature variation rate of the cooking cavity is greater than a preset value.

Abstract
A cooking apparatus equipped with heaters and a method of controlling the same. An aspect of the present invention is to increase convenience of a user by identifying a kind of an accessory, such as a wire rack, a crumb tray or the like, present in a cooking cavity based on a variation in an inner temperature of a cooking cavity at an initial operating stage of a cooking mode using the heaters and automatically performing the ON/OFF control mode of the heaters suitable for a corresponding accessory. A cooking apparatus is provided including two or more heaters installed in a first position of a cooking cavity heating food, the crumb tray is inserted in a second position of the cooking cavity and is used to contain the food in cooking modes using the heaters, and a temperature detection unit is installed between the first and second positions to detect an inside temperature of the cooking cavity. When a temperature variation rate of the cooking cavity detected by the temperature detection unit is greater than a preset value, the crumb tray is determined to be used as a cooking accessory, so an ON/OFF state of the heaters is controlled to be suitable for the cooking mode using the crumb tray.
