[0003] In existing gas water heaters, the burner, heat exchanger, and exhaust hood are typically connected together and then installed as a whole in a tank for fixed assembly. Disadvantages include: the exhaust hood is prone to vibration under the impact of flue gas flow, resulting in high noise levels and a poor user experience. Utility Model Content

[0004] The purpose of this utility model is to propose a mounting bracket for a fume hood and a gas water heater, which solves the problem that existing fume hoods are prone to vibration under the impact of flue gas flow, and has low noise.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A mounting bracket for a smoke hood includes: a support plate having a support connection hole thereon; and an L-shaped fitting plate having a fitting connection hole at one end and the other end connected to the support plate, wherein the support plate and the fitting plate form a set angle.

[0007] In one preferred embodiment, the edge of the support plate is bent to form a support plate flange, and the edge of the bonding plate is bent to form a bonding plate flange. The support plate flange and the bonding plate flange together form an annular structure surrounding the outer periphery of the mounting bracket.

[0008] In one preferred embodiment, a clearance gap of a predetermined width is formed between the end of the flange of the support plate and the end of the flange of the bonding plate.

[0009] In one preferred embodiment, the support plate has two support connection holes for riveting, and the two support connection holes are equal in shape and area.

[0010] In one preferred embodiment, the line connecting the centers of the two supporting connecting holes is parallel to the extension direction of the supporting connecting holes.

[0030] This embodiment discloses a mounting bracket for a fume hood and a gas water heater including the mounting bracket, such as... Figure 1 and Figure 2 As shown, the gas water heater includes a mounting bracket 1, a housing 2, a fume hood 3, and a flue 4. Both the fume hood 3 and the flue 4 are located inside the housing 2. The fume hood 3 has a fume vent, and the flue 4 connects to the fume vent. The fume hood 3 has a hood connection hole 31. One end of the mounting bracket 1 is connected to the hood connection hole 31, and the other end of the mounting bracket 1 is connected to the housing 2, thereby fixing the fume hood 3 to the inner wall of the housing 2.

[0031] The specific structure of the housing 2 is not limited; any hollow shell capable of accommodating structures such as the exhaust hood 3 and the exhaust pipe 4 is acceptable. In this embodiment, the housing 2 includes a rear shell that can be connected to a wall and a front cover that is connected to the rear shell. The exhaust hood 3 can be fixedly connected to the rear shell via a mounting bracket 1, which saves more internal space in the housing 2 and is beneficial for the miniaturization design of the gas water heater.

[0032] To improve the stability of the installation structure, the gas water heater includes two mounting brackets 1. The two mounting brackets 1 are located on both sides of the center of the exhaust hood 3, with the L-shaped opening of one bonding plate 12 facing or backing onto the L-shaped opening of the other bonding plate 12. The forces on the two mounting brackets 1 are more balanced, and the load-bearing capacity is stronger.

[0033] like Figure 1 and Figure 3As shown, the mounting bracket 1 for the fume hood includes a support plate 11 and an L-shaped fitting plate 12. The support plate 11 has a support connection hole 111. One end of the fitting plate 12 has a fitting connection hole 121, and the other end is connected to the support plate 11. The support plate 11 and the fitting plate 12 form a set angle. The specific value of the set angle is not limited. In this embodiment, the support plate 11 and the fitting plate 12 are perpendicular to each other, that is, the support plate 11 and the fitting plate 12 form an L-shaped structure, so as to fix the fume hood 3 to the rear shell of the housing 2, improve the strength of the connection structure, and make the connection more reliable and stable.

[0034] The L-shaped bonding plate 12 increases the contact area with the rear shell of the housing 2, and the force on the exhaust hood 3 can be distributed to the entire bonding plate 12, which makes the exhaust hood 3 more stable and firm to be connected to the housing 2, making it safer to use, extending the service life of the whole machine, with a low failure rate and strong load-bearing capacity; it also reduces the vibration amplitude and vibration frequency of the exhaust hood 3, resulting in less noise and a better user experience.

[0035] Based on the above structure, the edge of the support plate 11 is bent to form a support plate flange 112, and the edge of the bonding plate 12 is bent to form a bonding plate flange 122. The support plate flange 112 and the bonding plate flange 122 form a ring structure around the outer periphery of the mounting bracket 1. The flanges can improve the overall strength of the mounting bracket 1, preventing deformation or even damage to the mounting bracket 1 due to the pulling of structures such as the fume hood 3, making it safer to use, and making the connection between the fume hood 3 and the housing 2 more secure and stable.

[0036] A clearance notch 13 of a predetermined width is formed between the end of the support plate flange 112 and the end of the bonding plate flange 122 to prevent mutual compression at the junction of the support plate flange 112 and the bonding plate flange 122. The specific shape of the clearance notch 13 is not limited. In this embodiment, the edge of the mounting bracket 1 made of sheet metal is flanged. At the bending line where the support plate 11 and the bonding plate 12 need to be bent, a triangular notch is cut out of the flange. After folding the mounting bracket 1 along the bending line, the support plate 11 and the bonding plate 12 are connected. The two sides of the triangular notch are close to each other, finally forming a generally narrow clearance notch 13.

[0037] To improve the stability of the connection, two support connection holes 111 are provided on the support plate 11 for riveting. The support plate 11 is connected to the fume hood 3 by riveting, and the number of riveting connection points is increased to two, making the connection structure more stable and reliable, and improving production efficiency. The two support connection holes 111 are of equal shape and area, so the force on the two riveting connection points is basically equal, resulting in more balanced force distribution, stronger load-bearing capacity, and safer use.

[0038] In this embodiment, the line connecting the centers of the two support connection holes 111 is parallel to the extension direction of the support connection holes 111. After the fume hood 3 and the housing 2 are fixedly connected, the support plate 11 needs to withstand the pulling force from the fume hood 3 and the housing 2 to both sides. By making the line connecting the centers of the two support connection holes 111 basically consistent with the extension direction of the support connection holes 111, the pulling force between the fume hood 3 and the housing 2 can be applied to the two support connection holes 111 simultaneously, increasing the load-bearing capacity and stability of the support plate 11 and improving the user experience.

[0039] Based on the above structure, a reinforcing rib 14 is formed at the connection between the support plate 11 and the bonding plate 12. The reinforcing rib 14 is connected to both the support plate 11 and the bonding plate 12. Even under large tensile forces, the support plate 11 will not bend relative to the bonding plate 12. The overall shape of the mounting bracket 1 is more stable, the connection structure is safe and reliable, and there are few safety hazards. The specific shape of the reinforcing rib 14 is not limited, as long as it can improve the strength of the connection between the support plate 11 and the bonding plate 12.

[0040] To reduce the installation difficulty of the fume hood 3, in this embodiment, the fitting connection hole 121 is an elongated hole (or waist-shaped locking hole) for locking, and the extension direction of the fitting connection hole 121 is perpendicular to the plane of the support plate 11. The term "elongated hole" means that the length of the fitting connection hole 121 is greater than its width. After bolts and other connecting parts pass through the fitting connection hole 121, they can move relative to the fitting connection hole 121 along its length, thereby adjusting the position of the fume hood 3 relative to the housing 2. Even if there are errors in the processing dimensions of the fume hood 3 and the housing 2, or the opening position of the connection hole, the fume hood 3 and the housing 2 can be connected together by adjusting the position of the connecting parts in the fitting connection hole 121. After installation, the connecting parts are tightened in the fitting connection hole 121, with the head of the connecting parts pressing against the edge of the fitting connection hole 121. Friction prevents relative movement of the connecting parts in the fitting connection hole 121, resulting in a more robust connection structure and easier assembly and disassembly.

Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention. The scope of the present invention is determined by the scope of the appended claims.
