Claim 9:
10. A method of controlling a multi-stage cleaning process of a cooking apparatus including a cooking chamber and a temperature sensor to detect a temperature in the cooking chamber, comprising:
performing a first stage cleaning process, the first stage cleaning process comprising:
controlling a heat source to increase a current temperature in the cooking chamber to a preset first temperature; and
controlling the heat source to maintain the preset first temperature in the cooking chamber to burn contaminants in the cooking chamber until a preset first time elapses to complete the first stage cleaning process; and
automatically performing a second stage cleaning process after completing the first stage cleaning process, the second stage cleaning process comprising:
controlling the heat source to automatically increase the maintained preset first temperature in the cooking chamber to a preset second temperature which is higher than the preset first temperature in response to an elapse of the preset first time; and
controlling the heat source to maintain the preset second temperature in the cooking chamber to burn contaminants in the cooking chamber that have not been burned in the first stage cleaning process until a preset second time elapses to complete the second stage cleaning process; automatically performing a third stage cleaning process after completing the second stage process, the third stage cleaning process comprising:
controlling the heat source to automatically increase the maintained preset second temperature in the cooking chamber to a preset third temperature which is higher than the preset second temperature in response to an elapse of the preset second time; and
controlling the heat source to maintain the preset third temperature to burn contaminants in the cooking chamber that have not been burned in the first stage cleaning process and the second stage cleaning process until a preset third time elapses to complete the third stage cleaning process.
