[0002] In the prior art, a gas water heater will make a lot of noise during operation, especially the noise generated when the motor drives the impeller to rotate. As the motor runs at high speed, the motor will vibrate slightly, thereby making a certain amount of mechanical noise.

[0003] In the "A Gas Water Heater Smoke Exhaust Structure" disclosed in the publication number CN209639266U, it includes a motor, a bracket assembly, an impeller, a volute assembly and a smoke hood. The impeller is arranged in the volute assembly, the motor is fixed to the volute assembly through the bracket assembly, and the rotating shaft of the motor is connected to the impeller; the air inlet of the volute assembly is connected to the air outlet of the smoke hood; the smoke hood is provided with a guide plate inside, and the guide plate divides the inside of the smoke hood into a first smoke channel and a second smoke channel along the direction of the smoke. However, the bracket assembly has a simple structure and insufficient supporting force. It only connects the motor and the volute assembly. In subsequent use, the motor shakes at high speed, causing mechanical noise. Summary of the invention

[0004] In order to overcome the above-mentioned defects in the prior art, a reinforced support for a gas water heater fan is provided for supporting the motor to prevent the motor from shaking and generating mechanical noise.

[0005] The technical solution of the utility model is as follows: a reinforced support for a gas water heater fan, assembled between a smoke hood and a volute; the upper surface of the reinforced support is a fitting surface, on which an embedding groove is provided, which is nested with a reinforcing rib provided on the volute; the lower surface of the reinforced support is a connecting support surface, which is fitted with the upper surface of the smoke hood.

[0006] Preferably, the fitting surface is a curved panel, and the curvature of the fitting surface is the same as the curvature of the volute.

[0007] Preferably, the embedding groove is opened in the middle of the fitting surface.

[0008] Preferably, a plurality of locking fixings for connecting the smoke collecting hood are provided on the side surface of the reinforcing support.

[0009] Preferably, the plurality of locking fixing members are each provided with a through hole, and the smoke collecting hood is provided with locking holes corresponding to the through holes.

[0010] Preferably, the through hole and the locking hole are fixedly connected by screws.

[0011] Preferably, a plurality of locking fixing members are equidistantly mounted on the side surface of the reinforcing support.

[0012] Preferably, the length of the connecting support surface is the same as the length of the smoke collecting hood.

[0013] Preferably, the volute is equipped with a motor for driving the fan to rotate.

[0014] Preferably, a plurality of locking fixings are mounted on a side of the reinforcing support facing the motor.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] A reinforced support for a gas water heater fan, which is assembled between a smoke hood and a volute, thereby enhancing the stability between the smoke hood and the volute, indirectly improving the stability of the motor, and avoiding mechanical noise caused by the shaking of the motor when running at high speed; an embedding groove is provided on the fitting surface, and the embedding groove is used to nest with the reinforcing ribs provided on the volute, thereby increasing the contact area between the support and the volute, improving the stability of the connection, and reducing the loosening or deformation of the reinforced support due to factors such as vibration or temperature changes; the supporting surface is tightly fitted with the upper surface of the smoke hood, ensuring that the reinforced support can stably support the smoke hood when bearing various forces generated by the operation of the fan, preventing it from shifting or deforming.

[0017] Furthermore, the fitting surface of the curved panel can better match the shape of the volute, achieving a tighter fit. This design not only increases the contact area and makes the stress distribution more uniform, but also reduces the stress concentration caused by assembly gaps or deformation, thereby avoiding structural damage or loosening. The design with the same curvature makes the nesting between the reinforcing support and the volute more precise, enhances the stability of the connection, and helps reduce displacement or deformation caused by vibration or external force.

[0018] Furthermore, the embedded groove in the middle position can evenly distribute and increase the force borne by its support. Whether it is the vibration generated by the operation of the fan or the force applied from the outside, the combination of the embedded groove and the reinforcing ribs can effectively disperse these forces, prevent damage caused by stress concentration, and optimize the balance and stability of the overall structure.

[0019] Furthermore, the side of the reinforcement support is provided with a number of locking fixtures, which are used to connect the smoke hood, improving the stability of the entire structure and the convenience of installation; the locking fixtures make the installation process more convenient and efficient. The operator can easily fix the reinforcement support on the smoke hood through simple operations, such as rotating or pressing the fixtures; saving installation time, reducing installation difficulty, and improving work efficiency.

[0020] Furthermore, by making the through hole on the locking fixture correspond to the locking hole on the smoke hood, the connection between the reinforcing support and the smoke hood can be ensured to be more accurate and stable. This design avoids the problem of loose connection or looseness caused by position deviation or improper installation, thereby ensuring the stability and reliability of the entire gas water heater fan structure.

[0021] Furthermore, the through holes and the locking holes are fixed by screws. This connection method is simple, practical, firm and reliable. It can effectively connect the supporting surface and the smoke hood tightly together, and the screw connection has a high load-bearing capacity and shock resistance, which can ensure that the smoke hood remains stable when subjected to external forces or vibrations.

[0022] Furthermore, the equidistantly assembled locking fixtures make the connection between the reinforcement support and the smoke hood more uniform and stable. Each fixture bears equal force distribution, effectively avoiding stress concentration or excessive force on a single point, thereby improving the stability of the entire structure.

[0023] Furthermore, the design of the same length enables the reinforcement support to completely cover the upper surface of the smoke hood, thereby achieving full contact between the two; the contact area between the connection support surface and the smoke hood is increased, the stability of the connection is improved, and it also helps to disperse and balance the various stresses generated during the operation of the fan, reducing the risk of stress concentration and damage; the same length also simplifies the installation process. Operators do not need to make complex adjustments or positioning, they only need to align the connection support surface of the reinforcement support with the upper surface of the smoke hood to achieve quick and accurate installation.

[0024] Furthermore, a motor for driving the fan to rotate is mounted on the volute, and a reinforced support is mounted between the smoke hood and the volute, which indirectly improves the stability of the motor and avoids mechanical noise caused by shaking of the motor when running at high speed.

[0025] Furthermore, a plurality of locking fixtures are assembled on the side of the reinforcing support facing the motor, and operators can more conveniently approach and operate these fixtures during installation or maintenance, thereby improving work efficiency, reducing operating difficulty, and making the entire installation and disassembly process smoother.

[0026] Other features and advantages of the present invention will be disclosed in detail in the following specific implementations and drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The following is an explanation and description of the technical scheme of the embodiment of the utility model in conjunction with the drawings of the embodiment of the utility model, but the following embodiment is only a preferred embodiment of the utility model, not all. Based on the embodiment in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the utility model.

[0033] In the following description, terms such as "inside", "outside", "up", "down", "left", "right", etc. that indicate directions or positional relationships are only used to facilitate the description of the embodiments and simplify the description, and do not indicate or imply that the referred device or element must have a specific direction, be constructed and operated in a specific direction. Therefore, it should not be understood as a limitation on the present invention.

[0034] like Figure 1 to Figure 2 As shown, a reinforced support for a gas water heater fan is installed between a smoke collecting hood 2 and a volute 3, and a motor 5 for driving the fan to rotate is installed on the volute 3, thereby enhancing the stability between the smoke collecting hood 2 and the volute 3, indirectly improving the stability of the motor 5, and avoiding mechanical noise caused by shaking of the motor 5 when running at high speed;

[0035] Among them, the upper surface of the reinforcing support 1 is a fitting surface 1-1, and the fitting surface 1-1 is provided with an embedding groove 1-1-1. The fitting surface 1-1 is an arc-shaped panel, and the curvature of the fitting surface 1-1 is the same as the curvature of the volute 3, which ensures that the reinforcing support 1 and the volute 3 can be perfectly fitted, and the stability of the entire structure is improved. The arc design of the fitting surface 1-1 can also disperse the vibration and force generated when the fan is running, reduce stress concentration, and thus extend the service life of the entire gas water heater fan; the embedding groove 1-1-1 is opened in the middle of the fitting surface 1-1, and is nested with the reinforcing rib 3-1 provided on the volute 3, which enhances the connection strength between the reinforcing support 1 and the volute 3, and also makes the entire structure more compact and beautiful. At the same time, due to the nesting effect of the embedding groove 1-1-1 and the reinforcing rib 3-1, the vibration and noise when the motor 5 drives the fan to run can be effectively reduced, and the user experience is improved.

[0036] The lower surface of the reinforced support 1 is the connecting support surface 1-2, which ensures that it can fit closely with the upper surface of the smoke hood 2; the length of the connecting support surface 1-2 is the same as the length of the smoke hood 2, which enhances the contact area between the two, improves the stability of the connection, and makes the entire structure more coordinated and beautiful.

[0037] Furthermore, the side of the reinforced support 1 is provided with a plurality of locking fixtures 4 for connecting the smoke hood 2, which are used to connect the smoke hood 2 and the reinforced support 1. In this embodiment, usually two locking fixtures 4 are provided, which are assembled on the side of the reinforced support 1 facing the motor 5. When performing installation or maintenance, the operator can more conveniently approach and operate the locking fixtures 4, thereby improving work efficiency, reducing operating difficulty, and making the entire installation and disassembly process smoother.

[0038] Furthermore, several locking fixtures 4 are provided with through holes 4-1, and the smoke hood 2 is provided with locking holes 2-1 corresponding to the through holes 4-1. The screw passes through the through holes 4-1 and is screwed into the locking holes 2-1, thereby realizing a fastened connection between the reinforcing support 1 and the smoke hood 2. Several locking fixtures 4 are equidistantly assembled on the side of the reinforcing support 1. The equidistant assembly method ensures that each locking fixture 4 can be evenly stressed, thereby improving the stability and reliability of the connection. The equidistant assembly simplifies the installation process. The operator can quickly determine the installation position based on the fixed distance between the fixtures without the need for complicated measurement and positioning. This not only improves the installation efficiency, but also reduces the error rate during the installation process.

[0039] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Those skilled in the art should understand that the utility model includes but is not limited to the contents described in the drawings and the above specific implementation. Any modification that does not deviate from the functional and structural principles of the utility model will be included in the scope of the claims.
