[0026] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0027] In the description of this application, it should be understood that the terms "bottom", "inside", "outside", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0028] In the description of the present application, unless otherwise specified, “plurality” means two or more.

[0029] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted" and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0030] In the prior art, gas water heaters are often placed above the kitchen faucet, with the bottom of the appliance roughly level with the user's shoulders or head. When a user turns on the faucet to wash dishes or vegetables, the noise generated by the internal operation of the gas water heater can easily be transmitted directly through the bottom panel and reach the user's ears. This can significantly affect the user's experience during actual use, resulting in a poor user experience.

[0031] In order to solve the above technical problems, the following Figures 1 to 4 , describing the embodiments of the present utility model.

[0032] According to an embodiment of the present invention, on the one hand, Figures 1 to 4 As shown, a gas water heater is provided, comprising a shell 1 and a noise reduction pad 2.

[0033] Specifically, if Figure 1 or Figure 3 As shown, the noise reduction pad 2 is arranged inside the shell 1 and attached to the bottom of the shell 1.

[0034] Specifically, if Figures 1 to 4 As shown, a device installation through hole 1011 is provided at the bottom of the shell 1, and an avoidance through hole 201 and / or avoidance notch 204 is opened on the noise reduction pad 2, and the avoidance through hole 201 and / or avoidance notch 204 are arranged corresponding to the device installation through hole 1011.

[0035] This gas water heater has a noise reduction pad 2 attached to the bottom of the shell 1. Through the sound absorption or sound insulation characteristics of the noise reduction pad 2, it can effectively absorb the vibration and noise during the operation of the gas water heater, such as the noise generated by the combustion chamber, fan, water pump, etc. inside the gas water heater, and at the same time reduce the noise generated by the operation of the gas water heater from being transmitted from the bottom of the shell 1, thereby significantly reducing the noise level during the operation of the equipment and improving the user experience.

[0036] An avoidance through-hole 201 and / or avoidance notch 204 corresponding to the equipment installation through-hole 1011 at the bottom of the shell 1 is provided on the noise reduction pad 2, so that the noise reduction pad 2 avoids the equipment at the bottom of the shell 1 through the avoidance through-hole 201 and / or avoidance notch 204, so that the noise reduction pad 2 can be installed at the bottom of the shell 1, ensuring unobstructed use of the equipment installation through-hole 1011, not affecting the assembly, maintenance and operation of the gas water heater, and ensuring the normal connection and function of the internal components of the gas water heater.

[0037] Specifically, the noise reduction pad 2 can be made of existing sound insulation or sound absorption materials such as sound-absorbing cotton, sound insulation foam, rubber pad, etc. In the embodiment of the present application, there is no specific restriction on the material of the noise reduction pad 2.

[0038] Specifically, the noise reduction pad 2 is attached to the bottom of the housing 1. The noise reduction pad 2 can be attached to the bottom of the housing 1 by gluing or fixing with fasteners. In the embodiment of the present application, there is no specific limitation on the connection method between the noise reduction pad 2 and the bottom of the housing 1. In addition, the fitting design of the noise reduction pad 2 and the bottom of the housing 1, coupled with the precise correspondence between the avoidance through-hole 201 and the device installation through-hole 1011, makes the installation and removal of the noise reduction pad 2 simple and quick, facilitating the maintenance and upgrade of the equipment, and reducing maintenance costs and time.

[0039] Specifically, the avoidance through-hole 201 is arranged in a one-to-one correspondence with the equipment installation through-hole 1011. The avoidance through-hole 201 can be set as an opening in the form of an oblong hole, a rectangular hole or other shapes. The size of the avoidance through-hole 201 is adapted to the size of the equipment installation through-hole 1011 to ensure that the avoidance through-hole 201 avoids the equipment component at the equipment installation through-hole 1011. In the embodiment of the present application, no specific restriction is imposed on the shape of the avoidance through-hole 201.

[0040] Specifically, one or more avoidance through-holes 201 can be provided. One avoidance through-hole 201 can correspond to one device mounting through-hole 1011 , or one avoidance through-hole 201 can correspond to multiple adjacently arranged device mounting through-holes 1011 . In the embodiment of the present application, there is no specific restriction on the number of avoidance through-holes 201 .

[0041] It should be noted that the equipment installation through hole 1011 can be a through hole for the water inlet pipe, water outlet pipe and gas pipe to pass through the bottom of the shell 1, or it can be an installation through hole for equipment such as a gas valve, water valve or power cord installed at the bottom of the shell 1. In the embodiment of the present application, there is no specific restriction on the position and shape of the equipment installation through hole 1011.

[0042] In one embodiment, Figure 1 or Figure 3 As shown, the noise reduction pad 2 is fixed to the inner surface of the bottom of the shell 1 by bonding.

[0043] The noise reduction pad 2 is fixed to the bottom of the housing 1 by bonding, ensuring that the noise reduction pad 2 is firmly fixed to the bottom of the housing 1, ensuring that the noise reduction pad 2 will not shift or fall off during the operation of the gas water heater, and maintaining its noise reduction effect. At the same time, bonding ensures that the noise reduction pad 2 is tightly attached to the bottom surface of the housing 1, forming a flat contact surface, avoiding additional noise caused by gaps or voids.

[0044] Adhesive fastening is often simpler and faster than screw or clamp fastening, reducing installation time and cost while also reducing vibration and noise caused by loose mechanical fasteners.

[0045] Specifically, the noise reduction pad 2 can be bonded to the bottom of the housing 1 by an adhesive, such as a double-sided adhesive, a high-temperature resistant or waterproof adhesive, etc. The noise reduction pad 2 can also be bonded to the bottom of the housing 1 by hot melt adhesive or Velcro. In the embodiment of the present application, there is no specific limitation on the bonding method of the noise reduction pad 2.

[0046] In one embodiment, Figure 3 As shown, the shell 1 includes a bottom plate 101 and a side plate 102, and the side plate 102 is arranged around the circumference of the bottom plate 101. The noise reduction pad 2 includes a main pad 202 and two side pads 203. The two side pads 203 are respectively arranged at both ends of the length direction of the main pad 202. The main pad 202 is fitted with the inner surface of the bottom plate 101, and the two side pads 203 are bent and fitted with the inner surfaces of the side plates 102 on opposite sides.

[0047] Since there is a gap at the connection between the bottom plate 101 and the side plate 102 of the shell 1, the main pad 202 is covered on the bottom plate 101, and the side pads 203 at both ends of the main board are covered on the inner surface of the side plate 102, so that the main pad 202 and the side pads 203 seal the gap at the connection between the bottom plate 101 and the side plate 102, reducing the air circulation between the inside of the shell 1 and the outside, forming a better sealing effect, not only reducing the noise inside the gas water heater from leaking to the outside through the gap, but also effectively isolating the lateral noise, achieving all-round noise control.

[0048] It should be noted that the shell 1 includes a panel (not shown in the figure), and the panel is the side panel 102. The side panel 102 is arranged around the bottom plate 101 to form a closed structure, which increases the overall rigidity and stability of the shell 1. At the same time, the combination of the side panel 102 and the noise reduction pad 2 helps to form a complete sound insulation barrier.

[0049] Specifically, the housing 1 is generally configured in a rectangular parallelepiped shape, the bottom plate 101 can be configured in a rectangular shape, and four rectangular side plates 102 are arranged around the circumference of the bottom plate 101. The shape of the housing 1 can be adaptively configured according to the actual use environment, and in the embodiments of the present application, the shape of the housing 1 is not specifically limited.

[0050] Specifically, the side pads 203 and the main pad 202 can be connected by later splicing, or they can be integrally formed. In the embodiment of the present application, there is no specific restriction on the connection method between the side pads 203 and the main pad 202.

[0051] Specifically, the side wing pad 203 can be attached to the side panel 102 by bonding, or by snap connection or fastener connection. In the embodiment of the present application, there is no specific restriction on the way the side wing pad 203 and the side panel 102 are attached.

[0052] In one embodiment, Figure 4 As shown, the main pad 202 and the two side pads 203 are integrally formed.

[0053] The integrated design of the main pad 202 and the side pads 203 eliminates the seam between them, reducing potential noise leakage paths, forming a more closed sound barrier, and improving the overall noise reduction effect. This also facilitates installation of the noise reduction pad 2 on the bottom of the housing 1, eliminating the need to align and secure the main pad 202 and side pads 203 separately, reducing installation time and potential installation errors.

[0054] When the noise reduction pad 2 is made of flexible material, the noise reduction pad 2 can be directly manufactured by cutting. When the noise reduction pad 2 is installed, due to the characteristic that the flexible material can be bent to adapt to the use environment, the part where the noise reduction pad 2 fits with the bottom plate 101 forms the main pad 202, and the part where the noise reduction pad 2 fits with the side plate 102 forms the side pad 203.

[0055] In one embodiment, Figure 3 As shown, the coverage area of each wing pad 203 is smaller than the area of the corresponding side panel 102 .

[0056] Because the wing pads 203 have a relatively small footprint, material usage can be reduced, thereby lowering production costs. While ensuring adequate noise reduction, material usage can be rationally planned to avoid unnecessary waste. The smaller footprint allows for more flexible installation, adapting to side panels 102 of varying sizes and shapes, thereby enhancing the versatility and applicability of the noise reduction pad 2.

[0057] Specifically, the side wing pads 203 can be configured to have any shape such as a rectangle or an arc. In the embodiment of the present application, the shape of the side wing pads 203 is not specifically limited.

[0058] In one embodiment, Figure 4 As shown, the thickness of each wing pad 203 is adapted to the thickness of the main pad 202 .

[0059] Because the side pads 203 and main pad 202 have the same thickness, the overall structure of the noise reduction pad 2 is coordinated and consistent, helping to form a uniform sound barrier between the bottom plate 101 and the side plates 102. This ensures that sound energy is effectively absorbed or blocked in all directions, improving overall noise reduction performance. Furthermore, using materials of the same thickness simplifies the production process, improves production efficiency, and reduces production costs due to material differences.

[0060] Specifically, the thickness of the noise reduction pad 2 can be adaptively designed according to the noise reduction requirements and the installation space inside the shell 1. In the embodiment of the present application, there is no specific restriction on the thickness of the noise reduction pad 2.

[0061] In one embodiment, combined Figure 3 and Figure 4 As shown, the coverage area of the noise reduction pad 2 is adapted to the area of the base plate 101 .

[0062] Since the area of the noise reduction pad 2 is adapted to the bottom plate 101 , there is no need to cut or adjust the noise reduction pad 2 when installing the noise reduction pad 2 , which simplifies the installation process and improves production efficiency.

[0063] The coverage area of the noise reduction pad 2 is set to match the area of the base plate 101 to ensure that every part of the surface of the base plate 101 is covered by the noise reduction pad 2 without omission, thereby maximizing the prevention of noise inside the gas water heater from being transmitted through the base plate 101.

[0064] In one embodiment, the noise reduction pad 2 can be made of either sound-absorbing cotton or a damping pad.

[0065] When the noise reduction pad 2 is made of sound-absorbing cotton, the sound-absorbing cotton can effectively absorb the bottom noise in the gas water heater, thereby reducing the noise transmitted from the bottom of the gas water heater.

[0066] When the noise reduction pad 2 is a damping pad, it can prevent the noise in the gas water heater from passing through the damping pad, thereby reducing the noise transmitted from the bottom of the gas water heater, and the performance of the damping pad is more stable in a high temperature environment.

[0067] Specifically, the sound-absorbing cotton can be made of existing sound-absorbing materials such as polyester fiber, glass fiber, or rock wool, and the damping pad can be made of existing damping materials such as rubber and polyurethane. The materials of the sound-absorbing cotton and damping pad can be customized according to the specific application environment and noise reduction requirements of the gas water heater to achieve optimal sound absorption and durability. In the embodiments of the present application, there is no specific limitation on the materials of the sound-absorbing cotton and damping pad.

[0068] In one embodiment, the sound-absorbing cotton is any one of polyester fiber cotton, bi-component cotton or melamine cotton.

[0069] The sound-absorbing cotton is made of polyester fiber cotton, which has good sound-absorbing effect and can effectively absorb medium and high-frequency sounds.

[0070] Sound-absorbing cotton uses two-component cotton, which can provide better structural stability. The combination of different densities helps to absorb sounds in a wider frequency range. It usually has good resistance to compression deformation and maintains long-term sound absorption performance.

[0071] The sound-absorbing cotton is made of melamine cotton, which is suitable for use in high temperature environments and can provide good sound absorption effects, especially in the absorption of high-frequency noise.

[0072] Specifically, the bicomponent cotton can be made of polypropylene (PP) and polyethylene terephthalate (PET).

[0073] In one embodiment, Figure 4 As shown, a plurality of avoidance through holes 201 are provided, and the plurality of avoidance through holes 201 are spaced apart along the length direction of the noise reduction pad 2 .

[0074] Multiple spaced-apart avoidance holes 201 can adapt to changes in the internal layout of different equipment. Whether it is the position adjustment of the pipeline or wire connection point, it can be matched through the corresponding avoidance holes 201, enhancing the versatility and flexibility of the noise reduction pad 2.

[0075] Specifically, by carefully arranging the position and size of the avoidance through-hole 201, the impact on the overall sound absorption or sound insulation effect of the noise reduction pad 2 can be minimized, while ensuring the normal operation of the equipment and achieving a balance between noise reduction and functionality.

[0076] The working principle of the gas water heater in this embodiment is described as follows:

[0077] The avoidance holes 201 on the noise reduction pad 2 are set one-to-one with the equipment installation holes 1011 on the bottom plate 101, the main pad 202 is attached to the bottom plate 101 by bonding, and the two side pads 203 are attached to the inner surfaces of the two side plates 102.

[0078] The noise reduction pad 2 has sound absorption or sound insulation properties, which can effectively absorb the noise generated during the operation of the gas water heater. Since the noise reduction pad 2 is arranged at the bottom of the shell 1, the noise reduction pad 2 can effectively reduce the noise transmitted from the bottom of the shell 1, thereby significantly reducing the noise level during the operation of the equipment and improving the user experience.

[0079] In the specific contents of the above-mentioned specific implementation methods, the various technical features can be combined in any non-contradictory manner. In order to make the description concise, not all possible combinations of the above-mentioned technical features are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0080] The specific contents of the above-mentioned specific embodiments only express several embodiments of the present invention. Although the description is relatively specific and detailed, it should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be based on the appended claims.
