The controller 42 controls the on / off state of the operation indicator lamp 32 through the lamp driver 58 whenever the heater 16 is turned on / off.

In addition, the control unit 42 down-counts the set cooking time stored in the cooking time storage unit 46, for example, by a built-in soft timer (program timer) from the operating point of the iris opening button 28c And the result is displayed on the timer display unit 30 by applying the reduced result to the timer display driver 52.

Therefore, when the cooking object is fried over the cooking time set under the control of the control unit 42 and the remaining cooking time displayed by the timer display unit 30 is " 00 " The control unit 42 proceeds to step 76 and outputs a warning sound to the heater 16 through the alarm signal output unit 56. In this case, And controls the off-cooking indicator lamp 32 and the indicator lamp 34 during heating through the control and the lamp driving unit 58 to stop the frying cooking process and return to the initial stage.

Alternatively, if the cooking time has not elapsed as a result of the determination in step 74, the heater 16 is continuously operated for a predetermined time (for example, 20 minutes) (YES in step 78), the process proceeds to step 80 to stop the operation of the heater 16 by the heater driving unit 48 and to stop the operation of the fryer oil tank 12 The operation of the heater 16 by the heater driving unit 48 is stopped even if the temperature of the frying oil in the heating chamber 14 has risen by at least 20 DEG C (YES in step 82) The alarm signal output unit 56 continuously outputs an alarm in step 86 when the abnormality of the alarm signal 16 occurs.

If the power switch 22 is turned OFF once after the abnormality of the heater 16 is recovered and then turned ON again, the normal state is returned. If the return control is performed in step 88, the routine proceeds to step 74 So that continuous fry cooking can be performed over the remaining cooking time.

On the other hand, in a state in which the frying cooking is practically performed, the transparent cover 36 is mounted on the control panel 14 in order to prevent the fry oil from scattering on the control panel 14 The control unit 42 controls the heater 16 by the heater driving unit 48 in response to the operation of the heater switch 40 provided on the side wall of the control panel 14, And the control unit 42 controls the start of the frying process even during the operation of the switch 38 during the iris opening.

When the set temperature check button 24d is operated while the above-described frying cooking process is being performed, the controller 42 controls the temperature display unit 50 to set the set temperature stored in the temperature storage unit 44, After the fryer cooking process is started by the operation of the iris opening button 28c, the controller 42 controls the cooking time setting buttons 28a, 28b so as to prevent the variation of the cooking time due to the mistake.

Meanwhile, the present invention is not limited to the above-described frying cooking process, and various changes and modifications can be made without departing from the technical gist and gist of the invention. For example, when frying cooking is performed under a certain cooking time and temperature The fry cooking may be performed based on the preceding temperature and cooking time stored in the temperature storage unit 44 and the cooking time storage unit 46. In this case, Is excluded.

In addition, when the return control by the switch 28c is performed after the fry cooking is forcibly stopped due to the abnormality of the heater 16, the control unit 42 performs inverse compensation on the forced stop time, It is preferable that the display unit 30 display the compensated remaining time so that the frying cooking process is performed.
