A smoke exhaust duct 16 having a discharge port 15 extending through the exhaust port 14 and facing outdoors is installed, and a discharge blower 17 is provided at the discharge port 15. Further, a removable grease filter 18 is provided in the smoke exhaust duct 16 near the suction port 13 in order to separate oil contained in the oil smoke. On the other hand, a damper 20 for closing the suction port 13 by a coil spring 19 made of a shape memory alloy is provided inside the suction port 13 on the upstream side of the grease filter 18, and a temperature sensor 21 is disposed near the suction port 13. 21 also stops the discharge blower 17. In addition, 22 indicates a bias spring for maintaining the inlet 13 in an open state when the coil spring 19 made of a shape memory alloy is below the operating temperature, the solid line arrow indicates the air flow, and the - dotted chain line arrow indicates the air flow. Shows the flow of oil flames, etc.

である。Next, the operation will be explained. During normal use, as shown in FIG. 1, the tension of the bias spring 22 is stronger than the tension of the coil spring 19 made of a shape memory alloy, so the suction port 13 is maintained in an open state. That is, when the exhaust blower 17 is driven in this state, a flow of air is generated from the intake port 13 to the exhaust port 15, and oil smoke, etc. generated along with the air flow sucked from the intake port 13 is sucked into the smoke exhaust duct 16. be done. Here, the oil contained in the oil smoke adheres to the grease filter 18 provided near the intake port 13 and is separated.
The purified air is discharged outdoors from the exhaust port 15.

When the flame 24 is drawn into the smoke exhaust duct 16 from the intake port 13 along with the intake air flow, the exhaust blower 17 is stopped by the output of the temperature sensor 2I, and at the same time, the shape memory alloy coil spring 19 is overheated and activated. In order to reach the temperature, the tensile force of the coil spring 19 made of shape memory alloy increases significantly more than the tensile force of the bias spring 22, and the damper 20 is immediately drawn toward the suction port 13, closing the suction port 13 and sucking. This is to cut off the flame 24.
