The microcontroller 45 controls the driving of the microwave oven according to the operation control signal input by the user. That is, the relay control circuit 30 is driven to drive a heater and the like. This results in cooking heating.

On the other hand, cooking data downloaded from an external device (in the embodiment of the present invention, a computer connected to the Internet) is transmitted to the interface 65 through the serial connector 90. The cooking data transferred to the interface 65 is controlled by the communication microcontroller 50 to be stored in the YPIROM 70 which is a data storage device.

As described above, when the user selects the cooking data stored in the YPIROM 70 under the control of the communication microcontroller 50 from the external device, the data moves as follows.

When the heating is to be performed using the cooking data downloaded from the external device, the user first selects the Internet menu key 140a additionally provided in the display device. As the Internet menu key 140a is selected as described above, the signal is transmitted to the microcontroller 45. In order to request the Internet menu from the microcontroller 50 for communication, the microcontroller 45 converts a low signal output from the CS port provided in the microcontroller 45 port to a high signal. Output to the communication microcontroller 50 (100th step).

The communication microcontroller 50 receiving the signal displays the Internet menu selected by the user through the second display unit 55 (operation 110). As described above, the microcontroller outputs a high signal from the CS port provided in the communication microcontroller 50 such that an internet menu is displayed on the second display unit 55 and a buzzer sound is generated through the buzzer circuit 25.

Switching to an output port outputs a low signal. Accordingly, each microcontroller that has received the low signal determines that a signal is received. At this time, the data communication proceeds in a synchronous or asynchronous manner.

In addition, the communication between the controller unit A and the communication controller unit B is performed by receiving / sending a protocol consisting of a command of a binary code for key input, cooking control variable request and movement, buzzer ringing request, and the like. At this time, the existing cooking heating function is performed through the control of the microcontroller 45, the control variable is transmitted to the microcontroller 45 by the communication controller unit 50.

As described above, when the user selects the Internet cooking key 140a and the buzzer sound is transmitted, the selected cooking data is selected using the selection dial 120 to execute cooking. That is, when the selection dial 120 provided in the display device is rotated, the data rotated by the selection dial 120 is transmitted to the microcontroller 45.

The microcontroller 45 detects a rotation direction and a rotation speed of a preset dial and transmits the same to the communication microcontroller 50. The communication microcontroller 50 has an Internet menu already designated according to the dial rotation speed and the rotation direction, and displays the Internet menu name designated according to the dial rotation speed and the rotation direction transmitted to the communication microcontroller 50. 55).

As described above, the cooking data selected by the user using the dial is displayed through the second display unit 55, and the gas oven range is driven according to the operation control signal input by the user. At this time, the microcontroller 45 requests the communication microcontroller 50 to transmit the cooking control variable to the controller unit A. FIG. Accordingly, the communication microcontroller 50 transfers the control variables stored in the ypyrom 70. In this case, the control variables are the heating time of the food, the output energy, the temperature of the thermistor. The microcontroller 45 receiving the control variable controls the load to proceed with heating by controlling the load according to the control variable.

As described above, the present invention further includes a communication controller in addition to the controller unit in the gas oven range, the existing cooking heating function is performed in the controller unit, and the control variable of the menu downloaded from the external device is data communication from the communication controller unit. By carrying out the cooking heating received through the, it is a basic technical idea that the function of the existing controller unit is expandable.
