Title: Exhaust device for cooking
Inventor: TAKUSHIMA WATARU
IPC: F24F7/06
Filed: 1991-09-11
Abstract: PURPOSE:To prevent the interior of a house surrounding a cooking range from catching a fire therefrom even when a fire breaks out from the cooking range during cooking and a flame gets into the duct of an exhaust device for cooking. CONSTITUTION:A suction port 3 is provided above the rear side of a cooking table 2, on which a cooking device 1 is placed, while the port 3 and an exhaust blower 8 are interconnected by a ventilation passage 7. A bypassing pipe 10 serving as another ventilation passage is branched from an intermediate point of the passage 7 so as to be connected to the blower 8 and a damper 13 is installed at the branch point of the passage 7 and the pipe 10 through a fuse 12 to usually close the pipe 10, so that oil in oil mist discharged is prevented from attaching to the interior of the pipe 10. Consequently, when a fire breaks out during the cooking and the abnormally high temperature of the flame causes the fuse 12 to melt and hence the damper 13 closes the passage 7, the pipe 10 provides another new passage, so that the flame in a duct is prevented from being propagated rearwardly from the branch point of the passage 7.
