Further, when the left burner 17 is extinguished, the signal is determined to be extinguished by the ignition / extinguishing determination means 5 by pressing the boiled button 12c again, and the cooking type determining means 6 incorporating this extinguishing signal is a signal indicating the end of cooking. The control means 8 to which is transmitted drives the stepping motor 24 to close the slide closing member 23 and turns off the display unit.

  The ventilation interlocking device of the present embodiment diverges indoors by operating the ventilating fan 4 in conjunction with the operation of the cooking device 2 by the control means 8 at the festival when cooking using the cooking device 2 as described above. Odor, humidity, smoke, oily smoke, etc. during cooking are exhausted, and after the cooking is finished, the ventilation fan 4 is continuously operated for a predetermined time and then stopped, and an abnormally high temperature of the cooking oil is detected to detect overheating of the cooking oil. If the cooking oil temperature has risen even after the fried food cooking is forcibly terminated later, it is determined that the cooking oil in the pan has ignited, and the operation of the ventilation fan is stopped to suppress the exhaust. Suppressing this exhaust prevents the pan flame from increasing.

  That is, the operation and action of the ventilation interlocking device will be described using the control flow of FIG. In order to cook the fried food using the left burner 17 with the temperature detecting means 7, when the user operates the fried food button 12c in S1, the ignition signal N is judged to be ignited by the ignition / extinguishing judgment means 5 (S2). The control means 8 that has taken in the ignition signal sends the ignition signal to the transmission means 9 in S3. The transmission means 9 transmits the infrared rays of the ignition signal to the reception means 10 of the ventilator 16 from the transmission window 15 of the cooking device 2 shown in FIG. The receiving means 10 receives the ignition signal from the transmitting means 9 in S5 and transmits it to the drive control means 11 (S6), and the drive control means 11 operates the ventilation fan 4 in S7.

  When fried food cooking is completed, when the user operates the grill button 12c again in S1, the fire extinguishing signal A dedicated to the fried food is determined to be extinguished by the ignition / extinguishing judgment means 5 in S2, and the fire extinguishing signal is sent to the cooking type judgment means 6 ( S8). When it is determined by the cooking type determination means 6 that the fire extinguishing signal is the end of fried food cooking (S13), the control means 8 that has taken this in S3 from the ventilator fan extended time storage unit 14 to the fried food cooking fan extension time (S14). Is started and the timer is started (S15), and the ventilation fan 4 continues to operate after cooking.

  Then, for example, when the fried food cooking fan extended operation time, which is a predetermined time of 6 minutes, is finished (S16), a fire extinguishing signal is sent from the control means 8 to the transmitting means 9 in S3, and the transmitting means 9 transmits the infrared signal of the fire extinguishing signal in S4. Is transmitted to the receiving means 10 of the ventilation device 16 from the transmission window 15 of the cooking device 2 shown in FIG. The reception means 10 receives the fire extinguishing signal from the transmission means 9 in S5 and transmits it to the drive control means 11 (S6), and the drive control means 11 stops the operation of the ventilation fan 4 in S7.

  Further, a case will be described in which cooking oil becomes abnormally hot during cooking of the deep-fried food, the temperature detecting means 7 detects overheating of the cooking oil, and the ventilation interlocking device is activated. During fried food cooking, the temperature detecting means 7 detects the temperature of the bottom of the cooking container (S17), and the control means 8 incorporating this detected temperature determines whether the cooking oil is overheated in S18. S3 to S7 are executed. When the temperature detection means 7 detects an overheating temperature of the cooking oil that leads to ignition, the control means 8 incorporating the detected temperature determines the cooking oil overheating in S18. Then, the control means 8 controls the gas flow rate control device 21 to automatically shut off the gas supply and extinguish the left burner 17 (forcibly ends frying cooking).

  On the other hand, the temperature detecting means 7 continues to detect the temperature of the cooking oil even after the left burner 17 is extinguished, and if the temperature of the cooking oil has decreased, the control means 8 that has issued a signal to end the frying cooking A timer is started by taking in the extended time (S14) of the fridge cooking ventilation fan operation (S20), and the ventilation fan 4 is continuously operated even after cooking. For example, when the fried cooking cooking fan extended operation time, which is a predetermined time of 6 minutes, ends (S21), a fire extinguishing signal is sent from the control means 8 to the transmitting means 9 in S3, and the transmitting means 9 transmits the infrared signal of the fire extinguishing signal in S4. Is transmitted to the receiving means 10 of the ventilation device 16 from the transmission window 15 of the cooking device 2 shown in FIG. The reception means 10 receives the fire extinguishing signal from the transmission means 9 in S5 and transmits it to the drive control means 11 (S6), and the drive control means 11 stops the operation of the ventilation fan 4 in S7.

  Further, as described above, if the temperature of the cooking oil continuously detected by the temperature detecting means 7 rises even though the control means 8 forcibly ends the cooking of the fried food due to overheating of the cooking oil, the cooking oil ignites. In S3, a fire extinguishing signal is sent from the control means 8 to the transmitting means 9 in S3, and the transmitting means 9 receives the infrared of the fire extinguishing signal in S4 from the transmitting window 15 of the cooker 2 shown in FIG. Call 10 The reception means 10 receives the fire extinguishing signal from the transmission means 9 in S5 and transmits it to the drive control means 11 (S6), and the drive control means 11 stops the operation of the ventilation fan 4 in S7. And the driving | operation of a ventilation fan is stopped, ventilation is suppressed, and the increase expansion of the flame of a pot at the time of burning to cooking oil is prevented.

  As described above, in the present embodiment, since the operation of the ventilation fan 4 is stopped after a predetermined time has elapsed by the control means 8 at the end of cooking of the deep-fried food, the ventilation fan is operated again to perform ventilation for the predetermined time. It is not necessary, and the burnt residual odor after cooking can be surely exhausted and removed. In addition, the temperature detecting means 7 detects an abnormally high temperature of the cooking oil, and the cooking fan 4 is stopped if the temperature of the cooking oil rises despite the fact that cooking of the fried food is forcibly terminated after detection of overheating of the cooking oil. Since it was set as the structure, the expansion of the flame of the cooking oil which the pot ignited can be prevented by suppressing exhaust.

  As described above, the present invention can reliably remove the residual odor and the like in the room after cooking, stop the operation of the ventilation fan in the event of an abnormality in the indoor ventilation technology and cooking oil in the pot, and increase the flame. It can also be applied to fire prevention devices that can be prevented.
