  When cooking is finished and the operation switch 16 or the grill operation switch 18 is operated to stop the operation of the cooking device 1, a signal for stopping operation is transmitted from the transmission unit 13. When the reception unit 8 receives the operation stop signal, the control unit 9 starts counting the delay operation time of the exhaust fan 5 and the illumination delay time of the illumination 7. Then, the control unit 9 turns off the illumination 7 when the illumination delay time elapses, and then stops the exhaust fan 5 when the delay operation time of the exhaust fan 5 elapses.

  An operation in the case of performing a plurality of cookings simultaneously will be described.

  The cooking device 1 transmits a position signal of the heating unit 10 to be used or an operation signal of the grill 11 at the start of cooking. Therefore, it is possible to grasp the cooking contents and the usage status for each heating unit 10 from these signals.

  The control unit 9 determines the delayed operation time and the illumination delay time of the exhaust fan 5 for each heating unit 10 by grasping the cooking content and the usage situation for each heating unit 10, and determines the end of cooking for each heating unit 10. To do.

  That is, when one cooking is finished and a signal for stopping the finished heating unit 10 is received, counting of the delayed operation time and illumination delay time of the exhaust fan 5 corresponding to the cooking content of the finished heating unit 10 is started. . Thus, the delay operation time and the illumination delay time of the exhaust fan 5 corresponding to the cooking contents of all the heating units 10 used are respectively counted.

  And when all cooking is complete | finished, the driving | operation of the heating cooking appliance 1 is stopped, and when all the time which has each counted passes, the illumination 7 will be light-extinguished and the exhaust fan 5 will be stopped.

  For example, a description will be given of a case where boiling water is selected in the heating unit 10a and cooking is performed simultaneously with the heating mode selected in the heating unit 10b. From the signal of the position of the heating unit 10 in use received with the start of cooking, the control unit 9 grasps that the heating unit 10a is boiling and the heating unit 10b is cooking in the heating mode, and responds to each. The delayed operation time and illumination delay time of the exhaust fan 5 are determined and set.

  And when cooking of the heating part 10b is complete | finished initially and the signal of the stop of the heating part 10b is received, the delay operation time 10 minutes and the illumination delay time 3 minutes of the exhaust fan 5 corresponding to a heating mode will be started. . After that, when cooking of the heating unit 10a is finished and the operation of the cooking device 1 is stopped and an operation stop signal is received, the hot water heating is supported separately from the delay operation time and the illumination delay time of the exhaust fan 5 corresponding to the heating mode. The exhaust fan 5 starts to be counted for a delay operation time of 3 minutes and a lighting delay time of 1 minute.

  When the illumination delay time 3 minutes corresponding to the heating mode elapses from the stop of the heating unit 10b, and when the illumination delay time 1 minute corresponding to boiling water elapses from the stop of the heating unit 10a, that is, the operation stop of the cooking device 1, Turn off the light. Further, the delay operation time 10 minutes of the exhaust fan 5 corresponding to the heating mode elapses from the stop of the heating unit 10b, and the delay operation time 3 minutes of the exhaust fan 5 corresponding to the boiling water elapses from the operation stop of the heating cooking appliance 1. Then, the exhaust fan 5 is stopped.

  On the other hand, when the illumination delay time of either of the heating units 10a and 10b has not elapsed, or when either of the heating units 10a and 10b is in operation, the illumination 7 is kept lit.

  As described above, in Embodiment 1 of the present invention, since the lighting duration time of the illumination 7 after cooking is determined is determined according to the type of cooking, the lighting time of the necessary lighting 7 that varies depending on the type of cooking. Can be adjusted appropriately, and the brightness of the kitchen can be maintained even after cooking. Moreover, when cooking continuously, the troublesomeness that the illumination 7 is turned off each time the cooking device is stopped between cooking can be eliminated, and the usability is improved.

  Also, the delay operation time of the exhaust fan 5 that discharges hot air, oily smoke, cooking odor, etc. after cooking and the lighting delay time for maintaining the brightness when working in the kitchen are set individually, and the lighting delay time is exhausted. Since it is set to be shorter than the delay operation time of the fan 5, the lighting 7 does not continue to be turned on until the exhaust fan 5 is stopped, and wasteful power consumption can be suppressed to save energy.

  The cooker hood of the present invention is linked to the operation of the cooking device, and after cooking is finished, the brightness of the kitchen can be adjusted even after the cooking is completed by appropriately adjusting the lighting time of the different lighting depending on the type of cooking. Therefore, it is also useful for a range hood for business use other than home use, such as a cafeteria or a hotel.
