In this state, the operation number or operation time of the functional component can be reset by operating the various operation buttons 61 of the operation panel 60. When the replacement time is near, reset the number of operation times or operation time of other functional parts that have been replaced. The control device 70 determines whether or not the number of operations or the operation time of the functional component that causes the notification has been reset. If it has been reset, the control device 70 determines “YES” in step 108 and proceeds to step 109. . In step 109, the control device 70 turns off the flashing display of “PC” on the display unit 62 a of the operation panel 60, sets the flag F 1 to 0, advances the program to step 111, and once ends. Thereafter, the control device 70 repeats the determinations of “YES” and “NO” in steps 101 and 102 until the number of operations or the operation time of the functional parts reaches the notification time again, and the gas combustion type heating cooker 10 The replacement or inspection time of each functional part will be managed again.

  On the other hand, after the replacement or inspection guidance is displayed on the display unit 62a in step 104, the user continues to operate the gas-fired heating cooker 10 without calling a serviceman, and the number of operation times or the operation time of the functional parts is replaced. Or the inspection time may be reached. When the number of operation times or the operation time of the functional component reaches the replacement or inspection time, the control device 70 determines “NO” and “YES” in steps 101 and 105 and advances the program to step 110. In step 111, the control device 70 executes the operation prohibition program of the gas combustion type cooking device 10 so that the cooking program cannot be executed, and the display unit 62 a of the operation panel 60 must be replaced or inspected. “PC” is turned on (notified) to indicate that it does not operate.

  After the process of step 110, the control device 70 executes the processes after step 106 as described above. Steps 106 to 109 are the same as those described above, and even after the operation prohibition program for the gas-fired heating cooker 10 is executed, replacement, repair, or inspection of all functional parts is performed by operating various buttons on the operation panel 60. If there is no input indicating that the operation has been performed, the control device 70 does not cancel the restriction on resetting the number of operation times or the operation time of the functional component in step 107. Since these descriptions are the same as described above, they are omitted.

  Thereby, in the gas combustion type heating cooker 10 of this embodiment, all the functional parts are replaced and repaired at the earliest replacement or inspection time of the functional parts such as the ignition devices 23 and 32 and the gas valves 27a and 40a. Or, it will be inspected, and there will be no inconvenience caused by frequent replacement of functional parts or notification of inspection time. Moreover, the failure | combustion of the gas combustion type cooking-by-heating machine 10 which exceeded the replacement | exchange time of a functional component can be prevented by replacing | exchanging, repairing, or checking all the functional components reliably at an early stage.

  In said embodiment, although demonstrated using the gas combustion type heating cooker 10 as one Embodiment of an apparatus, this invention is not limited to this, As an other apparatus, an electric heating type heating cooker, Similar effects can be obtained even with devices such as ice makers, refrigerators, and electrolyzed water generators.

  In the above embodiment, the ignition devices 23 and 32 and the fuel gas supply valves 27a and 40a have been described as the functional components of the gas combustion type cooking device 10, but the present invention is not limited thereto. However, even if the functional parts such as the blower fans 26 and 39 are used as other functional parts in addition to or in place of the above functional parts, the same operational effects can be obtained.

  In the above embodiment, the display unit 61a of the operation panel 60 has been described as the notification unit. However, the present invention is not limited to this, and a speaker is further added to notify by sound or the display unit 61a. At the same time, the same operation and effect can be obtained even when notification is given by sound from the speaker.
