2. Description of the Related Art Conventionally, a cooking exhaust device of this type has been disclosed in Japanese Patent Publication No. 60-53817.
It was a structure as shown in the gazette. However, in such a configuration, there is a problem that, in the event that a tentacle fire or the like occurs during cooking, there is a possibility that a surrounding building may be ignited through a duct, so that we have already adopted a method as shown in FIGS. 5 and 6. Has been proposed. In the figure, a suction port 19 is provided in the upper rear part of the cooking appliance table 2 having a cooking appliance 16 such as a gas stove.
13 is provided with a canopy 11 on top. Canopy 11 and airflow guide plate 13
And the back plate 12 together to form a hood. Reference numeral 17 denotes a temperature sensor for detecting the temperature of the bottom of the pot placed at the time of cooking 3 when the temperature detected by the temperature sensor 17 exceeds a predetermined value. The gas supply from 9 to the burner 10 is stopped, and the heating of the pot is stopped.

In the above configuration, oil, smoke, odor and the like generated during cooking are sucked from the front of the cooker table 2 by operating the blower 15 toward the inlet 19 along the canopy 11 and the airflow guide plate 13. It is guided by the flowing airflow, is sucked through the suction port 19, passes through the ventilation path 14 and the blower 15, and is discharged outside. If the cooker inadvertently leaves the cooker 16 burning while cooking, for example, the temperature of the cooking oil in the pot and the temperature of the pot bottom gradually increase, and finally exceed the temperature required for cooking. Will ignite the oil in the ceiling, but the temperature detected by the temperature sensor 17 is the temperature immediately before the ignition, and the control circuit 18 stops the gas supply from the gas supply pipe 9 to the burner 10 by the gas shut-off device 7. As a result, the temperature of the oil did not rise and a fire did not occur.

However, in such a conventional configuration, in a state where the pot is not placed on the virtue 3 and the burner 10 is in an empty firing state in which the burner 10 burns, the temperature sensor 17 is in the center of the burner 10. Cooling from the surroundings due to the ventilation flowing through the air, it does not rise above a certain temperature even if the air-fired combustion continues, so the control circuit 18
However, the gas shut-off device was not operated, and there was a problem that it was uneconomical to continue burning without air until the cook noticed. Also,
Since the heat of combustion is not consumed for cooking, the temperature of the canopy 11 may be higher than during cooking, the ventilation path and the exhaust blower may be hot, or a burn may occur if the cook touches it. There was also a problem of danger.

Means for Solving the Problems In order to solve this problem, the present invention has a suction port at the upper rear portion of a cooker table on which a cooker is arranged, and communicates with the suction port to the rear of the cooker table. The provided ventilation path, and has an exhaust blower provided in the ventilation path, for discharging the air sucked from the suction port, the bottom temperature of the pot placed on the cooker or the pot There is a temperature sensor for detecting the ambient temperature in the absence of the pan, a pan sensor for detecting the presence or absence of a pan on the cooker by a change in the vertical position of the temperature sensor, and a detection result of the pan sensor and the pan. Control means for operating a gas shut-off device for shutting off the supply of combustion gas to the cooker according to each case according to the detected temperature of the temperature sensor when there is no pan and when there is no pan is integrally provided with the cooker table. Of the cooking exhaust system It was a good thing.

Operation According to this configuration, when the cooking device is fired with no fire, the pan sensor does not detect the pan because there is no pan on the cooking device, but the temperature of the temperature sensor rises and exceeds a predetermined temperature due to combustion. At this time, the control means determines that the combustion is idling, activates the gas cutoff device, and stops the supply of gas to the cooking device.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. In the figure, reference numeral 4 denotes a temperature sensor for detecting the temperature of the bottom of the pot placed on the cooker 1 during cooking, and a base 4b attached to the cooker 1 and a base for closely contacting the pot bottom.
It is composed of a head 4a held by a spring so as to be able to move up and down with respect to 4b. When the lower end of the head 4a moves downward, it is possible to press the switch of the pan sensor 5 A protrusion is provided at the position. The pan sensor 5 is a push switch, which is pressed by the temperature sensor head 4a when the pan is placed on the top. Numeral 8 denotes control means for operating the gas shut-off device 7 by means of the detection temperature of the temperature sensor 4 and the detection means of the pan sensor 5 to stop the supply of gas from the gas supply pipe 9 to the burner 10. The other configuration is the same as the conventional example.

In the above configuration, if the cooker inadvertently leaves the cooker 1 burning without putting a cooking pot on the gotoku 3, the head 4a of the temperature sensor has no pot as shown in FIG. It is in a state protruding above gotoku 3, the protrusion does not press the push switch of the pan sensor 5, and the pan sensor 5 does not detect the pan. At this time, the temperature sensor 4 detects the ambient temperature near the center of the burner 10, and the ambient temperature is determined by the rising air flow due to combustion.
Due to the presence of the non-combustion airflow flowing from below to above the cooker 1, it is not higher than in the case where there is a pot,
It rises and stabilizes at a relatively low predetermined temperature. Therefore, when the detected temperature of the temperature sensor 4 exceeds a predetermined temperature that is relatively low even though the pan sensor 5 does not detect the pan, the control means 8 determines that the combustion state is the idling combustion, and the gas shutoff device 7
Is operated to stop the supply of gas to the burner 10, and the air-fired combustion ends.

As shown in FIG. 4, when the pot is put on the top 3 of the pot, the head 4a of the temperature sensor is pushed downward by the pot, and the protrusion pushes the push switch of the pot sensor 5, and the pot sensor 5 Detect the pot. At this time, since the temperature sensor 4 detects the temperature at the bottom of the pot, the control means 8 detects the relatively high temperature, which is the temperature immediately before the tempura oil ignites, as in the conventional example. The gas supply device 9 stops the gas supply from the gas supply pipe 9 to the burner 10 by the gas shut-off device 7 to prevent the ventilation path and the exhaust ventilation provided at the rear of the cooker table from becoming hot due to the idle combustion, and to prevent the fire. To prevent the occurrence of

Advantageous Effects of the Invention As is apparent from the above description of the embodiment, according to the present invention, when the pan sensor does not detect the pan and the temperature detected by the temperature sensor exceeds a relatively low predetermined temperature, the control means sets the gas. By operating the shut-off device and stopping the supply of gas to the burner, it is possible to prevent air-fired combustion, and the ventilation path and exhaust blower provided at the back of the canopy and the cooker table do not become hot, and there is no danger of burns. And an economical exhaust device for cooking can be obtained.
