That is, the heating heater 230 is operated so as to heat the widest range of the heating range of the heating heater 230 by the signal that the variable switch 450 is pressed once, and the variable switch 450 is pressed twice The heating heater 230 is operated so that the heating range of the heating heater 230 is heated by the signal so that the heating range of the heating heater 230 heats the intermediate range of the heating range and the variable switch 450 heats the narrowest range The heater 230 is operated.

The microcomputer controls the heating heater 230 so that the heating heater 230 is turned off by the signal that the variable switch 450 is pressed four times and the variable switch 450 is pressed five times By the signal, the heating heater 230 is controlled to be heated so as to heat the widest range of the heating range.

The microcomputer sequentially and repeatedly controls the operation and the heating range of the heating heater 230 according to the pressing signal of the variable switch 450 so that the user can select the operation and the heating range of the heating heater 230 Respectively.

When the heating heater 230 operates in a heating range desired by the user, the microcomputer proceeds to a third step S300 of initializing the signal transmission state of the variable switch 450 and locating the signal transmission state.

The microcomputer initializes the signal transmission state of the variable switch 450 by temporal control. That is, when the preset time elapses after the operation of the heating heater 230, the signal transmission state of the variable switch 450 is initialized. When the user operates the selection switch 420 during cooking, A heating range is proposed in the initial operating state.

More specifically, when the signal transmission state of the variable switch 450 is initialized and the user operates the selection switch 420 once in the current heating range, the heating range of the heating heater 230 is heated to the maximum extent The microcomputer controls the operation of the heater 230.

Of course, if the user inputs a program pre-inputted to the microcomputer so as to not initialize the signal transmission state of the variable switch 450 and the final state is stored and the user operates the selection switch 420 during cooking, The heater 230 is controlled in the subsequent operation in the last operation.

That is, when the heating heater 230 is operating to heat the intermediate range of the heating range, the microcomputer stores the operation of the variable switch 450 in the state of being pressed twice, The microcomputer recognizes the signal in which the variable switch 450 has been pressed three times and controls the heating heater 230 to heat the narrowest heating range.

When the user operates the selection switch 420, the selection switch 420 can select the heating range of the heating heater 230 sequentially and repeatedly by the same motion, that is, by the translational motion, 420 and the off-state operation of the heater 230 can be controlled.

The operation of the selector switch 420 causes the variable switch 450 to sequentially and repeatedly generate signals by the same motion, that is, by pressing the interlocking member 460 by the translational movement of the selection switch 420 So that the operation of the heater 230 can be performed by transmitting a signal to the micom.

According to the cooking apparatus of the present invention configured as described above, it is easy to change the heating range of the heat source for cooking food. As a result, the convenience of the user to use the cooking device is improved and the advantage of the use of the product can be expected. Therefore, the control method of the cooking device and the cooking device according to the present invention can be utilized The possibility is great.
