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; 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; controlling the heat source to maintain the preset second temperature in the cooking chamber to burn contaminants that have not been burned during the preset first time until a preset second time elapses: 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 in the cooking chamber to burn contaminants in the cooking chamber that have not been burned during the preset first time and the preset second time until a preset third time elapses. ### Claim 2 (depends on 1) The method according to claim 1, wherein each of the preset first time and the preset second time is five minutes or more. ### Claim 3 (depends on 1) The method according to claim 1, wherein the preset first temperature has a range of 250° C. to 300° C. ### Claim 4 (depends on 3) The method according to claim 3, wherein the preset second temperature has a range of 300° C. to 430° C. ### Claim 5 (depends on 1) The method according to claim 1, further comprising: controlling the heat source to automatically increase the maintained preset third temperature in the cooking chamber to a preset fourth temperature which is higher than the preset third temperature in response to an elapse of the preset third time; and controlling the heat source to maintain the preset fourth temperature in the cooking chamber to burn contaminants in the cooking chamber that have not been burned in the preset first time, the preset second time and the preset third time until a preset fourth time elapses. ### Claim 6 (depends on 1) The method according to claim 1, wherein the third preset time is thirty minutes or more. ### Claim 7 (depends on 5) The method according to claim 5, wherein the third preset time is five minutes or more, and the fourth preset time is thirty minutes or more. ### Claim 8 (depends on 4) The method according to claim 4, wherein the preset third temperature has a range of 430° C. to 450° C. ### Claim 9 (depends on 5) The method according to claim 5, wherein the preset first temperature has a range of 250° C. to 300° C., the preset second temperature has a range of 300° C. to 350° C., the preset third temperature has a range of 350° C. to 430° C., and the preset fourth temperature has a range of 430° C. to 450° C. ### Claim 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. ### Claim 11 (depends on 10) The method according to claim 10, further comprising: automatically performing a third fourth stage cleaning process after completing the second third stage process, the third fourth stage cleaning process comprising: controlling the heat source to automatically increase the maintained preset second third temperature in the cooking chamber to a preset third fourth temperature which is higher than the preset second third temperature in response to an elapse of the preset second third time; and controlling the heat source to maintain the preset third fourth temperature in the cooking chamber to burn contaminants in the cooking chamber that have not been burned in the first stage cleaning process, the second stage cleaning process and the third stage cleaning process until a preset third fourth time elapses to complete the third fourth stage cleaning process. ### Claim 12 (depends on 10) The method according to claim 10, wherein the preset first temperature has a range of 250° C. to 300° C., the preset second temperature has a range of 300° C. to 430° C., and the preset third temperature has a range of 430° C. to 450° C. ### Claim 13 (depends on 11) The method according to claim 11, wherein the preset first temperature has a range of 250° C. to 300° C., the preset second temperature has a range of 300° C. to 350° C., the preset third temperature has a range of 350° C. to 430° C., and the preset fourth temperature has a range of 430° C. to 450° C. ### Claim 14 (depends on 10) The method according to claim 10, wherein the third preset time is thirty minutes or more. ### Claim 15 (depends on 11) The method according to claim 11, wherein the third preset time is five minutes or more, and the fourth preset time is thirty minutes or more.
