PURPOSE: A coupling structure of a hood tube of a smoke discharging device for a roaster is provided to prevent the coupled part of a fixing tube and a suction tube from decoupling using a corrugated pipe.;CONSTITUTION: A coupling structure of a hood tube of a smoke discharging device for a roaster is composed as follows. The top end of a hood tube having a corrugated pipe(20) is coupled to a fixing pipe(10), and the bottom end is coupled to a suction pipe(30). Connecting rings(50) having multiple coupling protrusions are formed in the top and bottom ends of the corrugated pipe. Coupling grooves(12), composed of guide grooves(13) and mounting grooves(14), are formed in the bottom end of the fixing pipe and the top end of the suction pipe. The corrugated pipe is connected to the fixing pipe and the suction pipe by inserting the coupling protrusions into the mounting grooves through the coupling grooves.;COPYRIGHT KIPO 2011
