Abstract
The utility model relates to a fume exhaust system for a gas water heater, which comprises a motor, a centrifugal fan and a fume collecting hood. A downdraft preventing device is arranged in the air outlet of the centrifugal fan, and the fume collecting hood comprises a lower-opening hood body and an air guide pipe. The lower-opening hood body comprises a front panel, a back panel, two side panels and a top panel, and the top of the lower-opening hood body is provided with a fume outlet. A top plate and the side plate are integrally formed, and the junction of the top plate and the side plate is in curved transition. An included angle being an acute angle is formed between the top plate and the horizontal plane. The top plate and the side plate are fixedly connected with a front plate and a back plate, and a gas outlet is communicated with a gas inlet of the centrifugal fan. The top plate, the side plate and one side panel are integrally formed. As the structure is adopted, the junction of the top plate and the side plate is in curved transition to play a role of flow guiding, the resistance is reduced, the wind pressure is accordingly increased, and the energy consumption is reduced. The backflow can be effectively prevented.
