Disclosed herein is a method for preventing overheating of a microwave oven. The method comprises the steps of receiving information of a cooking condition and a cooking start command for current cooking, the cooking condition comprising a magnetron output level and a current cooking period, confirming pause duration from when preceding cooking was finished to when the current cooking is started, if it is determined that the magnetron output level is a preset magnetron output level or more, and determining a basic output period and a reference period for changing the magnetron output level corresponding to the confirmed pause duration, followed by operating the microwave oven at the preset magnetron output level after changing the magnetron output level to the preset magnetron output level, if it is determined that a driving period for changing the magnetron output level has passed the determined reference period.

What is claimed is: 1. A method for preventing overheating of a microwave oven including a controller for controlling a magnetron output level, comprising the steps of: (a) receiving information of a cooking condition and a cooking start command for current cooking, the cooking condition comprising a magnetron output level and a current cooking period; (b) confirming pause duration from when preceding cooking was finished to when the current cooking is started, if it is determined that the magnetron output level is a preset magnetron output level or more; and (c) determining a basic output period and a reference period for changing the magnetron output level corresponding to the confirmed pause duration, followed by operating the microwave oven at the preset magnetron output level after changing the magnetron output level to the preset magnetron output level, if it is determined that a driving period for changing the magnetron output level has passed the determined reference period for changing the magnetron output level. 2. The method according to claim 1, wherein at the step of (c), the microwave oven is operated at the magnetron output level input as the cooking condition during the basic output period. 3. The method according to claim 1, wherein the basic output period is differently set depending on the pause duration. 4. The method according to claim 2, wherein the basic output period is differently set depending on the pause duration. 5. The method according to claim 1, wherein the reference period for changing the magnetron output level is determined as a value obtained by summing a preceding cooking period, an elapsed time of the current cooking period and a weight value. 6. The method according to claim 5, wherein the preceding cooking period is determined as a value obtained by summing all preceding cooking periods, of which range is determined depending on the pause duration. 7. The method according to claim 5, wherein the weight value is determined depending on the pause duration. 8. A method for preventing overheating of a microwave oven including a controller for controlling a magnetron output level, comprising the steps of: (a) receiving information of a cooking condition and a cooking start command for current cooking, the cooking condition comprising a magnetron output level and a current cooking period; (b) confirming pause duration from when preceding cooking was finished to when the current cooking is started, if it is determined that the magnetron output level is a preset magnetron output level or more; (c) increasing a counter value for changing the magnetron output level if the pause duration is a preset period or less, and initializing the counter value for changing the magnetron output level if the pause duration exceeds the preset period; and (d) operating the microwave oven at the preset magnetron output level after changing the magnetron output level to the preset magnetron output level if the counter value for changing the magnetron output level is a preset value or more, and determining a basic output period and a reference period for changing the magnetron output level corresponding to the confirmed pause duration if the counter value for changing the magnetron output level is less than the preset value, followed by operating the microwave oven at the preset magnetron output level after changing the magnetron output level to the preset magnetron output level if it is determined that a driving period for changing the magnetron output level has passed the determined reference period for changing the magnetron output level. 9. The method according to claim 8, wherein at the step of (d), the microwave oven is operated at the magnetron output level input as the cooking condition during the basic output period. 10. The method according to claim 8, wherein the basic output period is differently set depending on the pause duration. 11. The method according to claim 9, wherein the basic output period is differently set depending on the pause duration. 12. The method according to claim 8, wherein the reference period for changing the magnetron output level is determined as a value obtained by summing a preceding cooking period, an elapsed time of the current cooking period and a weight value. 13. The method according to claim 12, wherein the preceding cooking period is determined as a value obtained by summing all preceding cooking periods, of which range is determined depending on the pause duration. 14. The method according to claim 12, wherein the weight value is determined depending on the pause duration.
