[0028] The following description of the present invention, with reference to the accompanying drawings, is provided to facilitate a more comprehensive understanding of the various embodiments of the present invention as defined in the claims and their equivalents. The description includes various specific details to assist understanding, but these details should be construed as merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications may be made to the various embodiments described herein without departing from the scope and spirit of the present invention.

[0029] In the description of the present invention, descriptions of directions, such as up, down, front, back, left, right, etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as a limitation on the present invention.

[0030] It will be understood that when one element (e.g., a first element) is “connected” to another element (e.g., a second element), the element may be directly connected to the other element or an intervening element (e.g., a third element) may be present between the element and the other element.

[0031] The embodiment of the present utility model provides a low-noise water heater, such as Figure 1 and Figure 2 As shown, the housing 100 and the fan 200 are fixed in the housing 100. The fan 200 is provided with an air outlet duct 210. The fan 200 generates airflow and blows the airflow out of the air outlet duct 210. The top surface of the housing 100 is provided with an opening through which the air outlet duct 210 extends out of the housing 100, and the smoke can be discharged to the outside through the air outlet duct 210.

[0032] A sealing ring 300 is sleeved on the air outlet pipe 210, and the sealing ring 300 abuts against the outer shell 100 to cover the gap between the air outlet pipe 210 and the inner wall of the opening, thereby sealing the gap. The noise inside the outer shell 100 will be blocked by the sealing ring 300 and will not easily spread outward through the gap between the air outlet pipe 210 and the inner wall of the opening, thereby reducing the working noise of the water heater.

[0033] In some embodiments, as Figure 1 and Figure 2 As shown, the surface of the air outlet pipe 210 is provided with a raised ring 220 surrounding the air outlet pipe 210. The raised ring 220 can circle the air outlet pipe 210, and the sealing ring 300 is located above the raised ring 220. The raised ring 220 supports and limits the sealing ring 300, preventing it from falling down along the air outlet pipe 210 and keeping it in the proper position on the air outlet pipe 210. The sealing ring 300 can continuously abut the housing 100 to ensure the sealing and sound insulation effect of the sealing ring 300.

[0034] In some embodiments, as Figure 1 and Figure 2 As shown, the outer diameter of the sealing ring 300 is larger than the diameter of the opening, so the sealing ring 300 is difficult to fall to the inside of the opening. The sealing ring 300 abuts the top surface of the housing 100, ensuring the sealing and sound insulation function of the sealing ring 300.

[0035] In some embodiments, as Figure 3 As shown, the housing includes a bottom housing 110 and a surface housing 120. The housing is configured as a split structure, which facilitates the assembly of components such as a burner, a heat exchanger and a fan 200 inside the housing.

[0036] The bottom shell 110 and the top shell 120 can be installed in a detachable manner such as screw fixing, snap connection, etc. to facilitate installation and disassembly.

[0037] In some embodiments, a sealing strip 400 is provided at the edge of the bottom shell 110, and the sealing strip 400 abuts against the surface shell 120. The sealing strip 400 can seal the gap between the surface shell 120 and the bottom shell 110. The noise inside the outer shell will be blocked by the sealing strip 400 and will not easily propagate outward through the gap between the surface shell 120 and the bottom shell 110, thereby further reducing the working noise of the water heater.

[0038] At the same time, dust is not easy to enter the interior of the housing through the gap between the surface shell 120 and the bottom shell 110, thereby improving the dustproof protection effect.

[0039] In this embodiment, the sealing strip 400 may extend over the entire edge of the bottom shell 110 , which provides a better sealing effect.

[0040] Further, such as Figure 4 and Figure 5 As shown, the edge of the bottom shell 110 is provided with a first flange 111 extending toward the inside of the bottom shell 110 , and the surface shell 120 includes a second flange 121 located at its edge and extending toward the inside thereof. The sealing strip 400 is fixed on the first flange 111 and abuts against the second flange 121 .

[0041] Since the thickness of the bottom shell 110 and the surface shell 120 are limited, the first flange 111 and the second flange 121 are equivalent to increasing the thickness at the edge of the bottom shell 110 and the thickness at the edge of the surface shell 120, respectively, thereby increasing the contact area between each and the sealing strip 400 and enhancing the sealing and sound insulation effect of the sealing strip 400.

[0042] The first flange 111 provides space for installing the sealing strip 400, increases the contact area with the sealing strip 400, and allows the sealing strip 400 to be more firmly fixed on the first flange 111. Specifically, the sealing strip 400 can be fixed on the first flange 111 by gluing, clamping, or the like.

[0043] Furthermore, the first flange 111 includes an abutting portion 112, a connecting portion 113, and a mounting portion 114. The abutting portion 112 is connected to the edge of the bottom shell 110. The connecting portion 113 is located at one inner end of the abutting portion 112 and is connected to the abutting portion 112 and the mounting portion 114, respectively. The sealing strip 400 is located between the mounting portion 114 and the second flange 121, and the abutting portion 112 abuts the second flange 121. As a result, the sealing strip 400 not only abuts the first flange 111 and the second flange 121, but also abuts each other, further enhancing the sealing between the first flange 111 and the second flange 121 and improving the sealing and sound insulation effect.

[0044] The sealing strip 400 may be fixed on the connecting portion 113 and / or the mounting portion 114 .

[0045] In some embodiments, the face shell 120 is integrally formed, which simplifies the molding process and enhances the structural strength of the face shell 120. Furthermore, this eliminates gaps caused by splicing, ensuring a sealed and soundproof effect. In this embodiment, the face shell 120 can be integrally formed using a sheet metal process.

[0046] Further, such as Figure 6 As shown, a tempered glass panel 130 is fixed to the front side of the face shell 120 to further enhance the sealing and sound insulation effect.

[0047] In some embodiments, as Figure 6 As shown, sound-absorbing cotton 140 is fixed to the inner side of the surface shell 120. The sound-absorbing cotton 140 not only absorbs sound but also prevents noise from resonating inside. The thickness of the sound-absorbing cotton 140 is preferably greater than 10 mm, and the density is preferably controlled at 8 to 9.5 kg / m3.

[0048] The terms and words used in the above description and claims are not limited to their literal meanings, but are merely used by the applicant to enable a clear and consistent understanding of the present invention. Therefore, it should be clear to those skilled in the art that the above description of various embodiments of the present invention is provided for illustration only and is not intended to limit the present invention as defined in the appended claims and their equivalents.
