By this operation, the reading device 16 reads the information code given to the lunch box. When the reading of the information code by the reading device 16 is successful, the control unit 22 causes the reading result notifying unit 24 to notify the user of the reading result. In this case, the operation of the reading result notifying unit 24 is, for example, an operation that emits a continuous sound “pea”, an operation that emits a sound “successful reading of the information code”, or both.

When the user is informed of the successful reading of the information code by the reading result notification unit 24, the user closes the front door 12 and presses the start button on the operation panel 11 after arranging the lunch box inside the heating cabinet 13.

If the reading of the information code is successful, the control unit 22 communicates with the server 31 and acquires the heating information corresponding to the type of food indicated by the information code from the server 31. Thereafter, when the user closes the front door 12 and presses the start button on the operation panel 11, the control unit 22 heats the lunch box in the heating chamber 13 according to the acquired heating information.

On the other hand, when reading of the information code by the reading device 16 fails, the control unit 22 causes the reading result notifying unit 24 to notify the user of the reading result. The operation of the reading result notification unit 24 in this case is, for example, an operation that emits an intermittent sound such as “beep, beep, beep”, an operation that emits a sound “the reading of the information code failed”, or both.

When the user is notified of the failure in reading the information code by the reading result notification unit 24, the user again enters the information code into the reading area 19 of the reading device 16 (so that the information code is illuminated with red light). Move the lunch box. Thereby, the operation when the reading of the information code is successful is as described above.

(Advantages of the heating cooker 1)
In the heating cooker 1, the reading device 16 is provided outside the heating chamber 13 and above the front opening 13 b of the heating chamber 13 as an installation position, and has a reading area 19 below the installation position. Yes.

Therefore, the information code can be read by the reading device 16 in the middle of a series of operations in which the user places the food to be heated on the heating chamber 13. Thereby, the user does not need an independent operation for reading the information code by the reading device 16, and the information code reading operation is facilitated.

Further, since the reading device 16 is installed above the front opening 13b of the heating chamber 13, the detection signal passage surface (the lower surface of the reading window 18) is hardly contaminated, and the temperature in the heating chamber 13 is reduced. It is less affected.

Further, a control frame 15 that accommodates the control board of the operation panel 11 is provided in a protruding manner at a position above the front opening 13 b of the heating chamber 13. The reading device 16 is provided so as to face downward from the lower surface of the control frame 15. Thus, the reading device 16 is installed using the control frame 15 that houses the control board of the operation panel 11.
