  About the induction heating cooking appliance comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  FIG. 3 is an operation flowchart of the device control means in the present embodiment, and the operation will be described with reference to FIG.

When power is turned on in step 51, power is supplied to each control unit, and each control unit and device control means start serial communication with each other, and in step 52, each control unit from each control unit. The device control means 14 receives the information 20, and the device control means 14 determines the model in step 53 according to the table of FIG. If it is a combination of control units existing in the table of FIG. 2B at step 54, it is determined at the time of the previous power-on at step 55, and the model information storage means 21 constituted by a nonvolatile memory such as an EEPROM. If there is model information previously determined in step 56, the process proceeds to step 57. In step 57, the previously determined model information is compared with the model information determined this time. If they match, the model is determined based on the matched model information, and the process proceeds to step 58 to start the operation. In step 58, heating is started in response to the user's key switch operation.

  If it is determined in step 54 that the control unit combination is not present in the table of FIG. 2B, the process proceeds to step 59. In step 59, the first display operation unit and the second display operation unit are abnormal. In step 60, the operation is stopped, and even if the user operates the device, the key switch is not accepted and only an abnormal display is performed.

  If there is no model information previously determined in step 56 (when power is turned on for the first time after completion of device assembly), the process proceeds to step 61. In step 61, the model information determined this time is stored in a non-volatile memory such as an EEPROM, the model is determined based on the model information determined this time, the process proceeds to step 58, and the operation is started.

  In step 57, the previously determined model information is compared with the model information determined this time. If they do not match, the process proceeds to step 59 to display an abnormality, and the operation is stopped in step 60.

  Further, in the present embodiment, when an abnormality is detected from the control unit information 20, all functions of the device are stopped, but there are partially compatible functions in the heating control unit and the display operation unit. In this case, by making this effective, a part of the functions can be used in the case of a failure and the convenience is improved.

  As described above, in the present embodiment, the device control unit that controls the whole does not include information for determining model information, determines the model according to the control unit information from each control unit, and controls each control. By determining the function of the unit and performing display operation and induction heating, the types of control units can be reduced, the number of development and manufacturing steps can be reduced, and the cost can be reduced.

  As described above, since the induction heating cooker according to the present invention assigns control unit information to each control unit and determines the model according to the control unit information, a control unit for determining the model is developed for each model. Therefore, it is not necessary to manufacture, and it is possible to improve the efficiency of development, design, and manufacture of various devices.
