An embodiment of the present invention provides a smoke guide plate, as shown in fig. 1, which includes a circular boss 100 and a base plate 200, wherein the base plate 200 surrounds an outer circumferential surface of the circular boss 100 and is connected to the outer circumferential surface of the circular boss 100. The circular boss 100 protrudes from the upper surface of the base plate 200, so that the top surface of the circular boss 100 is at a height greater than the upper surface of the base plate 200, which allows the circular boss 100 to be inserted into the smoke exhaust of the smoke cage. Specifically, the base plate 200 may be located at the bottom of the circular boss 100. The top surface of circular boss 100 is provided with and runs through its own first smoke exhaust hole 110 and a plurality of second smoke exhaust hole 120 along its thickness direction, and first smoke exhaust hole 110 is located the middle part of the top surface of circular boss 100, and specifically, the center of first smoke exhaust hole 110 can be located the axle center of circular boss 100. The second smoke discharge holes 120 are arranged around the first smoke discharge holes 110, and the number and the aperture of the second smoke discharge holes 120 and the aperture of the first smoke discharge holes 110 can be determined according to actual conditions.

Because this implementation is provided with first smoke exhaust 110 and second smoke exhaust 120 on the smoke deflector, the frequency of the noise that produces when the flue gas passes through first smoke exhaust 110 and second smoke exhaust 120 hardly keeps the same, simultaneously, because the combustor burning operating mode is difficult to keep the same, air current itself is unstable in the exhaust pipe, this has further increased the degree of difficulty that produces the same frequency noise in first smoke exhaust 110 and the second smoke exhaust 120, make the noise sound wave be difficult to with the resonance of gas heater, thereby effectively weakened the noise.

In some embodiments, the top surface of the circular boss 100 is provided with a duct 300, the duct 300 is abutted with the first smoke exhaust hole 110, the duct 300 plays a smoke guiding role, the inherent smoke guiding role of the smoke guiding plate cannot be ignored while the noise is reduced, and the smoke can flow more smoothly due to the presence of the duct 300.

Further, the joint of the duct 300 and the first smoke exhaust hole 110 is processed by fillet transition, so that the smoke can flow into the duct 300 more smoothly, and the smoke is prevented from accumulating at the local position of the bottom surface of the circular boss 100.

Further, the base plate 200, the circular boss 100 and the duct 300 are integrally connected, which simplifies the manufacturing process of the smoke guide plate, makes the smoke guide plate easy to form, and the integrally connected structure has superior structural strength. Wherein the guide tube 300 may be formed with a flange extending upward by means of stamping.

In some embodiments, the second smoke exhaust holes 120 are uniformly distributed on the top surface of the circular boss 100 relative to the first smoke exhaust holes 110, so that the smoke can be discharged upwards relatively uniformly, and the smoke can be prevented from accumulating at a local position on the bottom surface of the circular boss 100.

Further, the first and second smoke discharge holes 110 and 120 are circular holes, which allows the first smoke discharge hole 110 to be adapted to the shape of the duct 300.

Further, the aperture of the first smoke discharge hole 110 is larger than that of the second smoke discharge hole 120, so as to form a smoke discharge structure with multiple apertures, so that the frequency of the noise generated in the first smoke discharge hole 110 is more different from the frequency of the noise generated in the second smoke discharge hole 120.

Embodiments of the present invention also provide a smoke cage assembly, as shown in fig. 1 and 2, comprising a smoke cage 400, a smoke exhaust duct 500, and a smoke guide panel of any of the embodiments described above. The smoke exhaust port is arranged on the smoke hood 400 and can be positioned at the top of the smoke hood 400, and the smoke exhaust pipe 500 is fixed on the outer surface of the smoke hood 400 and is in butt joint with the smoke exhaust port. The smoke cage 400 is used to collect the smoke and guide the smoke to flow toward the smoke outlet, so that the smoke is finally discharged through the smoke discharge pipe 500. The bottom plate 200 is fixed on the inner wall of the smoke hood 400, the circular boss 100 is embedded in the smoke exhaust port, and the smoke guide plate is positioned through the circular boss 100, so that the smoke guide plate can be rapidly assembled at the smoke exhaust port conveniently. For further description of the smoke guide plate, reference may be made to the above-mentioned embodiments of the smoke guide plate, which are not described herein again.

In this embodiment, the outer diameter of circular boss 100 can be slightly less than the internal diameter of exhaust port, and this size that can make circular boss 100 and the size looks adaptation of exhaust port, the assembly of being convenient for also makes circular boss 100's horizontal area bigger as far as possible, and the corresponding first smoke exhaust 110 and the second smoke exhaust 120 that can set up bigger aperture make the flue gas circulation more smooth and easy. In order to enhance the stability of the smoke guide plate, the circular boss 100 may be welded or riveted to the inner wall of the smoke discharge port and/or the smoke discharge pipe 500. The base 200 may be fixed to the inner wall of the hood 400 by welding, or may be fixed to the inner wall of the hood 400 by fixing members such as screws.

In some embodiments, the outer side wall of the smoke cage 400 has a mounting bracket 410 secured thereto, and the smoke cage 400 can be secured to the housing of the gas water heater by the mounting bracket 410 to stabilize the smoke cage assembly.

Embodiments of the present invention also provide a gas water heater including a hood assembly of any of the above embodiments. Further description of the smoke cage assembly can refer to the embodiments of the smoke cage assembly described above, and will not be repeated herein.

The foregoing is a more detailed description of the present invention that is presented in conjunction with specific embodiments, and the practice of the utility model is not to be considered limited to those descriptions. It will be apparent to those skilled in the art that a number of simple derivations or substitutions can be made without departing from the inventive concept.
