Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to a noise-reducing housing and a gas water heater. Background Technology

[0002] The operating noise of gas water heaters has a significant impact on users and is an important factor in user experience. Due to limitations in manufacturing processes and costs, some existing gas water heaters allow noise generated by the operation of internal components to easily leak through gaps in the casing, increasing the perceived noise level and causing inconvenience to users. Utility Model Content

[0003] One of the technical problems to be solved by this utility model is to provide a noise-reducing housing that can reduce the user's perceived noise and improve the user experience while effectively controlling costs.

[0004] The second technical problem to be solved by this utility model is to provide a gas water heater that can reduce the user's perceived noise and improve the user experience while effectively controlling costs.

[0005] The first technical problem mentioned above is solved by the following technical solution:

[0006] A noise-reducing housing, used in a gas water heater, comprises a front shell and a bottom shell arranged sequentially, the front shell and the bottom shell being connected to form an accommodating cavity;

[0007] The front shell includes a first main board and a first surrounding plate group surrounding the edge of the first main board. The bottom shell includes a second main board and a second surrounding plate group surrounding the edge of the second main board. The first surrounding plate group surrounds the second surrounding plate group. The inner wall of the first surrounding plate group fits against the outer wall of the second surrounding plate group, forming a gap where the opening does not face the first main board.

[0008] The noise-reducing housing described in this utility model has the following advantages compared with the prior art:

[0009] The first enclosure panel is positioned to surround the second enclosure panel, meaning the inner wall of the first enclosure panel is flush with the outer wall of the second enclosure panel. This creates a gap between the first and second enclosure panel panels where the opening does not face the first main panel. This ensures that the opening of the gap does not face the direction in which the user normally uses the gas water heater. This design effectively reduces noise propagating from the gap into the housing cavity towards the direction in which the user normally uses the gas water heater, while effectively controlling costs. This reduces the user's perceived noise and improves the user experience.

[0015] In one embodiment, the first upper plate is provided with a second protrusion protruding toward the first lower plate at the position where the fastener is located. The second protrusion is provided with a recessed groove on the side away from the first lower plate. The second upper plate is provided with a second guide groove at the position corresponding to the second protrusion. The second protrusion and the second guide groove slide together and are connected by a fastener. The head of the fastener is located in the recessed groove.

[0016] In one embodiment, the upper and lower ends of the first side plate are respectively provided with a third flange and a fourth flange, the third flange being connected to the first upper plate and the fourth flange being connected to the first lower plate.

[0017] In one embodiment, the second upper plate has a fifth flange on both sides, and the fifth flange is connected to the upper part of the corresponding second side plate; the second lower plate has a sixth flange on both ends, and the sixth flange is connected to the lower part of the corresponding second side plate.

[0018] In one embodiment, a back plate is also included, which is disposed on the side of the bottom shell away from the front shell.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0041] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0042] In the description of this utility model, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0043] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0044] like Figures 1-7 As shown, this embodiment of the utility model provides a noise-reducing housing, including a front shell 1, a bottom shell 2, and a back plate 3 arranged sequentially. The front shell 1 and the bottom shell 2 are connected to form a cavity 4, in which components of a gas water heater, such as a burner, a fan, and a heat exchanger, are disposed. The back plate 3 is disposed on the side of the bottom shell 2 away from the front shell 1, so that the back plate 3 and the bottom shell 2 form an air inlet noise-reducing cavity 5, and the back plate 3 is provided with an inlet 6.

[0045] Specifically, the front shell 1 includes a first main board 11 and a first surrounding plate group surrounding the edge of the first main board 11. The bottom shell 2 includes a second main board 21 and a second surrounding plate group surrounding the edge of the second main board 21. The second main board 21 is provided with a connecting port 211 connecting the accommodating cavity 4 and the air inlet noise reduction cavity 5. The inlet 6 and the connecting port 211 are distributed far apart from each other. The first surrounding plate group surrounds the second surrounding plate group. The inner wall of the first surrounding plate group and the outer wall of the second surrounding plate group are attached to each other so that multiple gaps 8 are formed between the first surrounding plate group and the second surrounding plate group, and the opening of the gaps 8 does not face the first main board 11.

[0046] It should be understood that the seam mentioned in this embodiment specifically refers to the seam 8 that points from the inside of the noise reduction housing to the outside of the noise reduction housing. Similarly, the orientation of the seam is the direction in which noise propagates from the inside of the noise reduction housing to the outside of the noise reduction housing.

[0047] When the gas water heater is working, air enters the air intake noise reduction chamber 5 from inlet 6 and then enters the containment chamber 4 through the connecting port 211 to provide air for the burner. The noise generated by the components of the gas water heater in the containment chamber 4 is transmitted in the reverse direction. That is, the noise enters the air intake noise reduction chamber 5 through the connecting port 211 and then exits through inlet 6, so that the noise can be transmitted through a longer path, which can effectively reduce the noise and improve the user experience.

[0048] The noise-reducing housing ensures that the opening of the gap 8 between the first and second enclosure panels does not face the first main board 11, so that the opening of the gap 8 does not face the direction in which the user normally uses the gas water heater. This setting can effectively reduce the noise propagating from the gap 8 in the accommodating cavity 4 towards the direction in which the user normally uses the gas water heater, while effectively controlling costs. This reduces the user's perceived noise and improves the user experience.

[0049] Optionally, such as Figures 2-4 and combined Figure 7 As shown, the gap 8 includes a first gap 81, a second gap 82, and a third gap 83. The first enclosure panel assembly includes a first upper plate 12 disposed at the upper end of the first main plate 11, a first lower plate 13 disposed at the lower end of the first main plate 11, and first side plates 14 disposed on both sides of the first main plate 11. The first upper plate 12, the first lower plate 13, the first side plates 14, and the first main plate 11 are integrally formed. The second enclosure panel assembly includes a second upper plate 22 disposed at the upper end of the second main plate 21, a second lower plate 23 disposed at the lower end of the second main plate 21, and second side plates 24 disposed on both sides of the second main plate 21. The second upper plate 22, the second lower plate 23, the second side plates 24, and the second main plate 21 are integrally formed. The inner wall of the first upper plate 12 and the outer wall of the second upper plate 22 are attached to form a first gap 81, the inner wall of the first lower plate 13 and the outer wall of the second lower plate 23 are attached to form a second gap 82, and the inner walls of the two first side plates 14 are attached to the outer walls of the two second side plates 24 respectively to form a third gap 83.

[0050] In the direction from the first mainboard 11 to the second mainboard 21, the length of the first upper plate 12 is greater than the length of the second upper plate 22, so that the distance between the edge of the first gap 81 and the first mainboard 11 is greater than the distance between the edge of the first gap 81 and the second mainboard 21. The lengths of the two first side plates 14 are respectively greater than the lengths of the two second side plates 24, so that the distance between the edge of the third gap 83 and the first mainboard 11 is greater than the distance between the edge of the third gap 83 and the second mainboard 21. By setting the edges of the first gap 81 and the two third gaps 83 away from the user, at least half of the gaps 8 formed between the first and second enclosure groups have a distance between the edge of the first gap 8 and the first mainboard 11 greater than the distance between the edge of the second mainboard 21, thus further reducing the impact of noise, reducing costs, and improving the user experience.

[0051] Furthermore, the length of the first lower plate 13 is less than the length of the second lower plate 23, and the first lower plate 13 is provided with a first protrusion 131 protruding towards the first upper plate 12. The second lower plate 23 is provided with a first guide groove 231. When the first and second enclosure plates are connected, the first lower plate 13 is located outside the second lower plate 23, and the first protrusion 131 can slide into and be confined within the first guide groove 231. In this structure, by lengthening the second lower plate 23, the strength of the bottom shell 2 is increased. Furthermore, by providing the first protrusion 131 and the first guide groove 231 to cooperate with each other, the first guide groove 231 can play a guiding role during installation, making assembly more convenient. In addition, the cooperation between the first protrusion 131 and the first guide groove 231 can block noise propagating through the second gap 82 between the first lower plate 13 and the second lower plate 23, thereby reducing the outward propagation of noise.

[0052] In this embodiment, the first upper plate 12 and the second upper plate 22 are connected by fasteners 7 (which may be screws).

[0053] Optionally, such as Figures 4-6 As shown, the first upper plate 12 has a second protrusion 121 protruding towards the first lower plate 13 at the position where the fastener 7 is located. Multiple second protrusions 121 can be provided. A recessed groove 1211 is provided on the side of the second protrusion 121 facing away from the first lower plate 13. A second guide groove 221 is provided on the second upper plate 22 at the position corresponding to the second protrusion 121. When the first upper plate 12 and the second lower plate 23 are connected, the second protrusion 121 can slide into and be confined within the second guide groove 221. A through hole is provided at the bottom of the second protrusion 121 in the recessed groove 1211, and a threaded hole is provided at the bottom of the second guide groove 221. The fastener 7 passes through the through hole and is screwed into the threaded hole, with the head of the fastener 7 located within the recessed groove 1211. When the first upper plate 12 and the second upper plate 22 are connected, the second guide groove 221 provides a guiding function, and the head of the fastener 7 being positioned within the recessed groove 1211 makes the design more aesthetically pleasing.

[0054] Since the length of the first upper plate 12 is greater than the length of the second upper plate 22, the fastener 7 can be positioned close to the second main plate 21.

[0055] Optionally, the upper and lower ends of the first side plate 14 are respectively provided with a third flange 143 and a fourth flange 144. The third flange 143 is fitted and fixedly connected to the first upper plate 12, and the fourth flange 144 is fitted and fixedly connected to the first lower plate 13. This structure can improve the structural strength of the shell 1.

[0056] In this embodiment, both sides of the first upper plate 12 are provided with folded edges that are recessed into the accommodating cavity 4, and the third flanges 143 of the two first side plates 14 are respectively fitted and fixedly connected to the folded edges of the first upper plate 12. The third flanges 143 and the corresponding folded edges, as well as the fourth flanges 144 and the first lower plate 13, can be connected by welding or riveting.

[0057] Optionally, a fifth flange 222 is provided on both sides of the second upper plate 22, and the fifth flange 222 is connected to the upper part of the corresponding second side plate 24; a sixth flange 232 is provided on both sides of the second lower plate 23, and the sixth flange 232 is connected to the lower part of the corresponding second side plate 24. This structure can improve the structural strength of the bottom shell 2.

[0058] Optionally, the back panel 3 has an embossed pattern 311 on the side facing the air intake noise reduction cavity 5, which can further reduce the impact of noise on the user.

[0059] Specifically, refer to Figure 3 The back panel 3 includes a third main board 31, a third upper plate 32 disposed on the upper end of the third main board 31, and third side plates 33 disposed on both sides of the third main board 31. The third upper plate 32 and the two third side plates 33 are all connected to the side of the second main board 21 away from the first main board 11 to form an air intake noise reduction cavity 5. The lower end of the third main board 31 is spaced apart from the second main board 21 to form an inlet 6. The side of the third main board 31 facing the air intake noise reduction cavity 5 is provided with uneven embossing 311. The embossing 311 can be horizontal and vertical grooves that intersect horizontally and vertically, or it can be multiple diamond-shaped grooves. When noise propagates to the accommodating cavity 4, the noise can be weakened by collision and dissipation on the embossing 311, further reducing the noise.

[0060] Optionally, the connection port 211 is a louver provided on the second motherboard 21 or several small holes provided on the second motherboard 21.

[0061] In this embodiment, the first upper plate 12 is provided with a smoke pipe outlet 122.

[0062] This utility model embodiment also provides a gas water heater, including the above-mentioned noise reduction shell and a burner, fan, heat exchanger, etc. disposed in the air inlet noise reduction cavity 5.

[0063] This gas water heater effectively reduces noise by incorporating a noise-reducing casing, thereby minimizing its impact on users and enhancing their experience.
