The microcomputer 100 displays data input through the interface section 144 and starts the cooking operation. Furthermore, the microcomputer 100 controls the

operation of the microwave oven 200 according to the operation of the Internet command input section 130 and stores the input data in the memory 150.

The operation of the above-described embodiment will now be described with reference to Figures 7A and 7B.

The data receiving section 140 of the microwave oven 200 is connected with the RS232C serial port 310 of the personal computer 300 via the male jack 400 (See Figure 4). The user turns on the microwave oven 200 and connects the personal computer 300 to the Internet. The user receives the cooking data from a web site of the Internet. The cooking instructions may be downloaded using http or ftp, or some other custom protocol.

In order to obtain the cooking instructions, the"clicks"on the desired microwave oven cooking information (the menu name, power level, driving time, etc. ) displayed in the user's web browser which causes a request to be sent to a server for the cooking data to be sent to the personal computer 300. The received data is output via the RS232C serial port 310 of the personal computer 300 by the communication program installed in personal computer 300. The output data is fed to the data receiving section 140 via the jack plug 400. The data fed to the data receiving section 140 is converted into a form suitable for the microcomputer 100 at the interface section 144, and is then input to the microcomputer 100.

When detecting the input of a pulse signal from the interface section 144 (step Sl), the microcomputer 100 displays the cooking data input via the interface section 144 on the display section 30 (step S2). The cooking data includes the menu name, the power level, the cooking time, etc. , and further includes the cooking conditions usually pre-set in the cooking menu of a microwave oven. The user can check the cooking data obtained from the Internet since the cooking data is displayed by the display section 30.

On detecting the operation of the operation executing button 24 (steps S3 and S4), the microcomputer 100 performs cooking operation according to the corresponding

cooking data (step S4b). On completing the cooking operation, the microcomputer 100 returns to C to check if any buttons are operated (step S3).

On detecting the operation of the bookmark button 131 (step S5), while cooking data from the Internet is being displayed by the display section 30, the microcomputer 100 stores the displayed cooking data in the memory 150 (step S6), and returns to C. Meanwhile, if operation of the bookmark button 131 is detected without cooking data having been received from the Internet or cooking data being displayed by the displaying section 301, the microcomputer 100 displays the cooking data stored in the memory 150 sequentially according to the number of bookmark button operations.

If the microcomputer 100 detects operation of the adjusting button 133 (step S7), the user is enabled to select data to be adjusted from the input data using the select button 135, and adjust the selected input data (step S8) using buttons of the numeral input section 23.

The can user select one of these pre-stored cooking menus to be replaced by a new cooking menu obtained from the Internet using the select button 135 (step Sill). When selecting the cooking menu to be replaced, the user presses the confirm button 136. On detecting that the confirm button 136 is pressed (step S12), the microcomputer 100 deletes the cooking data of the selected pre-stored cooking menu and stores the newly obtained cooking data from the Internet (step S13). Then, the microcomputer 100 returns to C to check whether there whether any buttons are operated (step S3).

If the microcomputer 100 detects that the cancel button 137 is pressed instead of the confirm button 136 (step S14), the microcomputer 100 does not store the cooking data displayed by the displaying section 30 and simply returns to C to check whether there whether any buttons are operated (step S3).

If the microcomputer 100 detects operation of the reset button 138 (step S15), the microcomputer 100 displays the data stored in the memory 150 using the display section 30 (step S16). In this situation, when determining that the confirming button 136 is being pressed (step S17), the microcomputer 100 deletes the data currently stored in the memory 150 and stores the default data (step S18). The default data is the data pre-stored in the microcomputer 100. Furthermore, when detecting that the cancel button 137 has been pressed instead of the confirm button 136 (step S19), the microcomputer 100 returns to C. That is, after detecting operation of the reset button 138, the microcomputer 100 keeps checking for operation of the confirm button 136 and the cancel button 137.

On detecting operation of the delete button 132 (step S20), the microcomputer 100 displays the data stored in the memory 150 using the displaying section 30 (step S21). The user can then select the data to be deleted using the select button 135 (step S22). In this situation, when detecting operation of the confirming button 136 (step S23), the microcomputer 100 deletes the selected data from the memory 150 (step S24). Further, when detecting the operation of the cancel button 137 (step S25), the microcomputer 100 returns to C (step S3). As described above, after detecting operation of the deleting button 132 (step S20), the microcomputer 100 keeps checking for the operation of the confirm button 136 or the cancel button 137 (steps S23 and S25).

When the microcomputer 100 does not detect operation of the reset button 138 or the delete button 132 (steps S15 and S20), the microcomputer 100 returns to C (step S3).

As described above, in accordance with the microwave oven and controlling method of the present invention, the user can cook food by using cooking data received from the Internet, and he/she may adjust, replace or store the cooking data from the Internet as he/she pleases.
