PURPOSE:To provide an exhaust device which can be directly fitted to a combustion equipment, displaying a superior water-proofness and wind shielding characteristics, by fitting an exhaust pipe and a cylindrical exhaust cover in such a manner that the former has its opening projected outside the body of combustion equipment from the opening thereof and the latter includes a ceiling covering the opening of exhaust pipe. CONSTITUTION:An exhaust equipment 15 is constituted by an outer cylinder 16 provided as an exhaust cover and an inner cylinder 17. A plurality of exhaust ports 18 are provided at the peripheral wall of the outer cylinder 16, whereas an inner cylinder 17 is also provided with exhaust ports 19 at the upper portion of the exhaust ports 18. Since the inner cylinder 17 has an exhaust gas flow limiting member 22 provided at the portion thereof lower than the lowermost exhaust port 21 of outer cylinder 16, water drops 24 cannot enter into the body of combustion equipment through an exhaust cylinder connector 13 even when a rain fall 23 and the like enters into the exhaust equipment 15. Moreover, since the upper end of exhaust cylinder connector 13 is sharply converged with a tapered configuration, the water drops 24 entering along the outer periphery of inner cylinder 17 into the exhaust equipment 15 outflow along a top board 12, being facilitated by the configuration of inner cylinder 17 which has its lower part 20 formed as a tapered part of large diameter. |
