When the thawing button is turned on (YES), the processing proceeds to step S2.

In step S2, if it is determined whether the user selects the manual mode through the operation unit 15 and selects the automatic mode (NO), the user proceeds to the step S3 and presses the automatic thaw menu selection button of the operation unit 15 to the user. The automatic thawing menu is selected on the program of the microcomputer 23, and then the microcomputer 23 determines the weight of the food through the weight sensing unit 17 in the staff S4, and the staff in the staff S5. The thawing time and temperature are automatically set according to the auto thawing menu and weight selected in (S3, S4).

Subsequently, in the step S6, the microcomputer 23 determines whether the start button of the operation unit 15 is turned on, and if the start button is not turned on (NO), the step S6 or less is repeatedly performed. If the start button is on (YES), the process advances to step S7.

In step S7, when the microcomputer 23 recognizes the temperature T in the oven chamber 7 through the temperature sensing unit 19 and is in the automatic mode, the temperature T is set to the microcomputer A. Is determined to be abnormal or not, and in the manual mode, it is determined whether or not the temperature T is equal to or higher than the thawing temperature B manually set by the user's manipulation unit 15. If the temperature is less than the set temperature (A / B) (NO), the fan (15) interlocked with the step (S8) by going to the microcomputer 23 to output a control signal to the motor drive unit 25 to rotate the motor (13) The rotation is performed, and in step S9, the microcomputer 23 outputs a control signal to the oven burner driver 27 to ignite the oven burner 11, and proceeds to the step S10 to perform a thawing function.

In step S11, it is determined whether the time control button of the operation unit 15 is turned on. If the button is not turned on (NO), the process proceeds to the step S12 and the microcomputer 23 defrosts the end time at which the current time is set. If the current time is a few seconds before the end of the thawing time (YES), and if the current time is not a few seconds before the end of the thawing time (NO), the operation below the step (S10) is repeated. do.

The staff S13 outputs a control signal from the microcomputer 23 to the buzzer driver 29 to drive the buzzer 30 several times to generate an alarm sound, thereby informing the user that the thawing end time is reached, and then the staff S14. The control unit outputs a control signal from the microcomputer 23 to the oven burner driver 27 to extinguish the oven burner 11, and in step S15, the control signal is output from the microcomputer 23 to the motor driving unit 25. 13) Stop and end the operation.

On the other hand, if the manual mode is selected in the step S2, the process proceeds to the step S16 and the user operates the operation unit 15 to set the selected thawing temperature B and thawing time in the microcomputer 23, and the step ( S6) The following operation is performed.

When the temperature T of the oven chamber is equal to or higher than the set temperature A / B in the step S7 (YES), the control unit 17 proceeds to the step S17 and outputs a control signal from the microcomputer 23 to the display unit 31. Display the error mode and stop the thawing function.

Further, when the time adjustment button of the operation unit 15 is turned on in the step S11 (YES), the thawing time set by the user operating the time adjustment button is increased / decreased by moving to the step S18 and the microcomputer 20 Is set again, and the operation below the step S12 is performed.

In addition, the control method for performing the drying function in the thawing / drying apparatus of the gas oven range according to an embodiment of the present invention, as shown in Figure 4a and 4b, first, in the step (S1) gas In order to perform the drying function of the oven range, the microcomputer 23 determines whether the drying button of the operation unit 15 is turned on, and if the drying button is not turned on (NO), the process proceeds to the step S20 to perform the existing cooking function. When the drying button is turned on (YES), the process proceeds to step S2.

In step S2, if the user selects the manual mode through the operation unit 15 and selects the automatic mode (NO), the user advances to the step S3 and the user selects the automatic dry menu selection button of the operation unit 15. Operation is selected on the program of the microcomputer 23, and then, in step S4, the drying time and temperature are automatically set in accordance with the automatic drying menu selected in the step S3.

Subsequently, in the step S5, the microcomputer 23 determines whether the start button of the operation unit 15 is on, and if the button is not turned on (NO), the step S5 or less is repeatedly performed. When the button is turned on (YES), the flow advances to step S6.

In step S6, when the microcomputer 23 recognizes the temperature T in the oven chamber 7 through the temperature sensing unit 19 and is in the automatic mode, the temperature T is set to the microcomputer. In the case of the manual mode, it is determined whether the temperature T is equal to or higher than the drying temperature D manually set by the user's manipulation unit 15, and the temperature T If the temperature is lower than the set temperature (C / D) (NO), the fan 15 is moved to the step S7 and outputs a control signal from the microcomputer 23 to the motor driving unit 25 to rotate the motor 13 so as to cooperate with the fan 15. The rotation is performed, and in the step S8, the microcomputer 23 outputs a control signal to the oven burner driver 27 to ignite the oven burner 11, and proceeds to the step S9 to perform a drying function.

In step S10, if it is determined that the time control button of the operation unit 15 is turned on (NO), the control unit 15 proceeds to the step S11 and the microcomputer 23 is at the end of drying time at which the current time is set. If it is determined a few seconds ago, if the current time is not several seconds before the drying end time (NO), the operation below the step S9 is repeated, and if the current time is several seconds before the drying end time (YES), the staff (S12). Going to

The staff S12 outputs a control signal from the microcomputer 23 to the buzzer driver 29 to drive the buzzer 30 several times to generate an alarm sound, thereby informing the user that the drying is finished, and then the staff S13. The control unit outputs a control signal from the microcomputer 23 to the oven burner driver 27 to extinguish the oven burner 11, and in step S14, the control signal is output from the microcomputer 23 to the motor driving unit 25. 13) Stop and end the operation.

On the other hand, when the manual mode is selected in the step S2, the process proceeds to the step S15 and the user operates the operation unit 15 to set the selected drying temperature D and drying time in the microcomputer 23, and the step ( S5) The following operation is performed.

When the temperature T of the oven chamber is equal to or higher than the set temperature C / D in the step S6 (YES), the control proceeds to the step S16 and outputs a control signal from the microcomputer 23 to the display unit 31. Display the error mode and stop the drying function.

In addition, when the time adjustment button of the operation unit 15 is turned on in the step (S10) (YES), go to the step (S17), the drying time set by the user to operate the time adjustment button is increased / decreased to the microcomputer 20 It is set again to, and performs the operation below the step (S11).
