[0010]
As described above, the gas grill is prepared by placing a fired object such as fish on the grill 5 and igniting the upper fire burner 3 and the lower fire burner 4 so as to bake the fired object from both sides. At this time, the exhaust in the upper portion of the roasting chamber 2 is exhausted from the upper portion of the roasting chamber 2 to the upper portion of the rear opening 9 and the exhaust port 14 through the upper exhaust passage 13 as shown by an arrow A in FIGS. Is done. Further, the exhaust gas passing through the roasting chamber 2 and above the grill net 5 is exhausted from the exhaust port 14 through the upper exhaust passage 13 and the upper portion of the rear opening 9 as shown by an arrow B in FIGS. Exhaust gas passing from the lower part of the roasting chamber 2 to the rear part of the grille 5 and in the vicinity of the grille 5 is shown in the lower part of the rear opening 9, the lower exhaust passage 11, the communication passage 12, and the upper part as shown by arrows C in FIGS.

Further, the exhaust in the vicinity of the tray 6 in the roasting chamber 2 is exhausted through the lower portion of the rear opening 9, the lower exhaust passage 11, the communication passage 12, the upper exhaust passage 13, and the exhaust port 14 as shown by an arrow D in FIG. Is done.
[0011]
Although the gas grill is configured as described above, in the case of the present invention, the temperature sensor 15 is disposed as a temperature detecting means in the vicinity of the communication path 12, and the exhaust gas is in contact with the exhaust passing through as indicated by the arrow C described above. The temperature is detected. Above the portion where the temperature sensor 15 is disposed, a projecting piece portion 17 is provided so as to project rearward from the rear end of the partition plate 10, and the exhaust easily contacts the temperature sensor 15 at the projecting piece portion 17. It is like that. Such protruding piece 17 may or may not be present. By providing the temperature sensor 15 in this way, it is possible to detect the temperature of the exhaust gas that passes in the vicinity of the object to be fired on the grill net 5, and to accurately detect the temperature of the object to be fired. As a result, when the object to be fired is abnormally heated above a predetermined temperature, the gas supply can be shut off to extinguish the fire, and the object to be fired can be prevented from being overheated or the object to be fired being ignited. . At this time, since the temperature of the object to be baked can be accurately detected, it is not extinguished even though the object to be baked has an abnormal temperature higher than a predetermined temperature, or the object to be baked is lower than a predetermined temperature. Nevertheless, there is no negative effect that the fire is extinguished.
[0012]
In the example shown in FIGS. 1 to 4, the temperature sensor 15 is provided only in the vicinity of the communication path 12 as described above. In the example of FIG. 5, the temperature sensor 15 is provided in the vicinity of the communication path 12 as the first temperature detecting means. In addition, a temperature sensor 18 as a second temperature detecting means is provided on the rear wall of the upper part of the upper exhaust passage 13, and a temperature sensor 19 as a third temperature detecting means is provided in the lower exhaust passage 11. It is provided at the bottom. The temperature sensor 15 can accurately detect the temperature of the object to be fired by detecting the temperature of the exhaust gas flowing as indicated by the arrow C. The temperature sensor 18 can detect the temperature of the exhaust gas flowing as indicated by arrows A and B, and can detect the atmospheric temperature in the roasting chamber 2. By detecting the temperature with this temperature sensor 18, it is possible to detect the magnitude of the heat input and also to detect the opening and closing of the grill door 7. In the case of the grill, since the thermal efficiency is low (the heat exchange rate is low), there is a correlation between the input and the temperature of the exhaust gas, and the size of the input can be detected by detecting the temperature of the exhaust gas with the temperature sensor 18. When the grill door 7 is opened and closed, the temperature of the exhaust gas detected by the temperature sensor 18 changes greatly, and the opening and closing of the grill door 7 can be detected. Further, the temperature sensor 19 can detect the temperature of the exhaust flowing as shown by the arrow D, and the temperature of the tray 6 can be detected. By detecting the temperature of the tray 6 in this way, the presence or absence of water in the tray 6 can be detected. In addition to detecting the temperature of the object to be baked by the temperature sensor 15 as described above, if the temperature sensors 18 and 19 detect the temperature, the temperature information detected by the temperature sensor 15 is detected by the temperature sensors 18 and 19. Can be corrected and more accurate control can be performed.
[0013]
FIG. 6 shows a flowchart of an example of control when only the temperature sensor 15 is provided. When an object to be fired is placed on the grill 5 and the burner is ignited, it is detected by a thermocouple whether or not the burner is ignited. That is, it is determined whether the electromotive force of the thermocouple is normal. If the electromotive force is not normal, it is determined that the thermocouple is not normally ignited, a buzzer is notified, and the fire is extinguished. If it is determined that the electromotive force is normal and ignited, it is determined whether or not the temperature of the object to be fired detected by the temperature sensor 15 is an abnormal temperature equal to or higher than a predetermined temperature. When it is determined that the object to be fired has been fired and the temperature has become abnormal, a buzzer is notified and the fire is extinguished.
[0014]
FIG. 7 shows a flowchart of an example of control when the temperature sensors 15, 18, 19 are provided. When an object to be fired is placed on the grill 5 and the burner is ignited, it is detected by a thermocouple whether or not the burner is ignited. That is, it is determined whether the electromotive force of the thermocouple is normal. If the electromotive force is not normal, it is determined that the thermocouple is not normally ignited, a buzzer is notified, and the fire is extinguished. When it is determined that the electromotive force is normal and ignition is performed, the temperature detected by the temperature sensor 18 is determined to determine whether the amount of heat input is large, medium, or small. Whether the temperature of the object to be fired detected by the temperature sensor 15 is an abnormal temperature equal to or higher than a predetermined temperature is determined according to the small size. At this time, the reference temperature for determining the abnormal temperature differs depending on the input large, medium, and small, and an accurate determination is made according to the input large, medium, and small. If it is determined that the temperature is equal to or lower than the abnormal temperature, baking of the object to be fired is continued. If it is determined that the temperature is abnormal, a buzzer is notified and the fire is extinguished. When firing of the object to be fired is continued at an abnormal temperature or lower, it is determined whether the grill door 7 is open or closed based on the temperature detected by the temperature sensor 18. If the grill door 7 is open, the grill door 7 is opened. It is determined whether or not a minute has elapsed, and if it is determined that one minute or more has elapsed, a buzzer is notified and the fire is extinguished. When it is determined that the grill door 7 is closed or within one minute after the grill door 7 is opened, the object to be baked is continued as it is. Further, when baking of the object to be fired is continued, the presence or absence of water in the tray 6 is determined by detecting the temperature of the temperature sensor 19, and when it is determined that there is no water in the tray 6, a buzzer is notified and the fire is extinguished. When it is determined that there is water in the tray 6, firing of the object to be fired is continued.
