Embodiment 1

[0017] Such as figure 1 , image 3 As shown, a smoke inlet air duct for a gas water heater of the present invention includes a front side plate 2, a left side plate 3, a right side plate 6, and a rear side plate 5, the top of the front side plate 2, the left side plate 3 The upper part, the top of the right side plate 6, and the top of the rear side plate 5 encircle the smoke outlet 4, the bottom of the front side plate 2, the bottom of the left side plate 3, the bottom of the right side plate 6, and the bottom of the rear side plate 5 The lower part encloses the smoke inlet 1, and the two sides of the rear side plate 5 in contact with the left side plate 3 and the right side plate 6 are provided with several rear side plate extensions 51 at intervals. The two sides that the right side plate contacts are provided with several front side plate extensions 21 at intervals, and the positions corresponding to the front side plate extensions and the rear side plate extensions on th...

Embodiment 2

[0020] Such as figure 2 As shown, the structure of the smoke inlet duct for a gas water heater of the present invention is basically the same as that of Embodiment 1, the difference is that a volute mounting plate 7 is fixedly connected to the smoke outlet, and the volute mounting plate 7 can be an independent part. Also can adopt the bending edge that front side plate 2 upwards is connected as a whole.

[0021] On the volute mounting plate 7, some volute mounting plate extensions 71 perpendicular to the volute mounting plate are punched out, respectively inserted into the elongated holes of the bent portion of the rear side plate, the elongated hole of the bent portion of the left side plate, and the right side plate. The elongated hole in the bent portion of the side plate bends and fastens the protruding portion 71 of the volute mounting plate.

[0022] In order to make the smoke inlet duct more durable, left side panel bending edges 33 are provided on the left side panel...

Abstract

The invention discloses a smoke inlet duct for a gas water heater. The smoke inlet duct comprises a front side plate, a left side plate, a right side plate and a rear side plate. The front side plate, the left side plate, the right side plate and the rear side plate define a smoke outlet and a smoke inlet. A plurality of rear side plate protruding parts are arranged at intervals on the two sides of the rear side plate that is in contact with the left side plate and the right side plate, a plurality of front side plate protruding parts are arranged at intervals on the two sides of the front side plate that is in contact with the left side plate and the right side plate, the left side plate is provided with left side plate long-thin holes, the right side plate is provided with right side plate long-thin holes, the front side plate protruding parts respectively penetrate the left side plate long-thin holes and the right side plate long-thin holes to be bent and fastened, and the rear side plate protruding parts respectively penetrate the left side plate long-thin holes and the right side plate long-thin holes to be bent and fastened. By the adoption of the technical scheme, the smoke inlet duct not only is provided with no welding point or rivet hole, effectively resists oil fume corrosion and prolongs service life, but also is simple in product structure, the tooling die cost is low, and the production efficiency is improved.

Description

technical field [0001] The invention relates to a gas water heater, in particular to a smoke inlet duct for a fan of a gas water heater. Background technique [0002] In the current prior art, the smoke inlet duct of the gas water heater is fixedly connected by welding or rivet riveting, and the welding or riveting is easily corroded and damaged; the patent with the publication number 202973539U discloses a smoke inlet duct of the gas water heater fan, although It solves the problem that the welding or riveting is easily corroded and damaged, but the fixed connection method of the outer buckle wrapping the outer flanging adopted in this invention patent has a complex product structure, high cost of tooling and molds, and low production efficiency. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a smoke inlet duct for a gas water heater fan. The smoke inlet duct for a gas water heater fan not only has a simple str...
