[0043] The first aspect of the present invention discloses a gas water heater housing structure, Figures 1 to 8 As shown, in some embodiments, the gas water heater shell structure includes a bottom shell 1100, a surface shell 1200 and a sealing strip 1300. The surface shell 1200 includes a cover plate 1210 and a first connecting portion 1220. The first connecting portion 1220 is arranged on the periphery of the cover plate 1210, and the first connecting portion 1220 protrudes from one side of the cover plate 1210. The first connecting portion 1220 surrounds the bottom shell 1100 and is connected to the bottom shell 1100, so that the surface shell 1200 covers the bottom shell 1100, thereby enclosing a receiving space 1400 between the surface shell 1200 and the bottom shell 1100, and the sealing strip 1300 abuts between the cover plate 1210 and the bottom shell 1100, thereby forming a seal between the surface shell 1200 and the bottom shell 1100.

[0044] In this embodiment, the face shell 1200 includes a cover plate 1210 and a first connecting portion 1220. When the face shell 1200 and the bottom shell 1100 are assembled, the first connecting portion 1220 surrounds the bottom shell 1100, thereby forming a limit for the face shell 1200, so that the face shell 1200 can better cooperate with the bottom shell 1100, and the face shell 1200 is not easily displaced relative to the bottom shell 1100, thereby further connecting and fixing the face shell 1200 and the bottom shell 1100. In addition, by arranging a sealing strip 1300 between the cover plate 1210 and the bottom shell 1100, the cover plate 1210 and the bottom shell 1100 jointly clamp the sealing strip 1300, thereby enhancing the sealing effect between the face shell 1200 and the bottom shell 1100.

[0045] Specifically, the gas water heater shell structure is described in detail below in conjunction with the gas water heater 1000. It can be understood that the gas water heater shell structure disclosed in the present invention is applicable to both ordinary gas water heaters 1000 (installed outside the bathroom environment) and balanced gas water heaters 1000 (which can be installed in the bathroom environment).

[0046] The outer shell structure of the gas water heater includes a bottom shell 1100, which has an opening 1115. Some components of the water heater are installed in the bottom shell 1100 through the opening 1115. The surface shell 1200 is assembled to the bottom shell 1100 to cover the bottom shell 1100, that is, the surface shell 1200 covers the opening 1115 of the bottom shell 1100, so that an accommodating space 1400 is enclosed between the surface shell 1200 and the bottom shell 1100, and some of the aforementioned components are located in the accommodating space 1400.

[0047] For example, taking the gas water heater 1000 as a reference when it is installed in the use environment, the user stands facing the gas water heater 1000, the side of the gas water heater 1000 facing the user is the front, the side away from the user is the back, the side corresponding to the user's left hand is the left, the side corresponding to the user's right hand is the right, the side close to the ground is the bottom (bottom), and the side away from the ground is the top (top). The bottom shell 1100 includes a back plate 1101, a top plate 1102, a bottom plate 1103, a left side plate 1104 and a right side plate 1105. The top plate 1102 is set on the top of the back plate 1101. The bottom plate 1103 is set at the bottom end of the back plate 1101, the left side plate 1104 is set on the left side of the back plate 1101, and the right side plate 1105 is set on the right side of the back plate 1101. The top plate 1102, the bottom plate 1103, the left side plate 1104 and the right side plate 1105 are surrounded by an opening 1115. The face shell 1200 is set on the front side of the back plate 1101 and is connected to the top plate 1102, the bottom plate 1103, the left side plate 1104 and the right side plate 1105, so that the face shell 1200 covers the bottom shell 1100 to seal the opening 1115 of the bottom shell 1100.

[0048] The cover 1200 includes a cover plate 1210 and a first connecting portion 1220. The cover plate 1210 is flat as a whole. Of course, the cover plate 1210 can be designed into other shapes according to actual needs. The first connecting portion 1220 is arranged on the periphery of the cover plate 1210. The first connecting portion 1220 extends along the circumference of the cover plate 1210, and the first connecting portion 1220 is protruded on one side of the cover plate 1210. Figure 3 、 Figure 4 and Figure 5 As shown, the bottom shell 1100 is located behind the face shell 1200, and the first connecting portion 1220 protrudes toward the rear on the rear side of the cover plate 1210. When the face shell 1200 is assembled to the bottom shell 1100, the first connecting portion 1220 surrounds the bottom shell 1100, that is, the first connecting portion 1220 surrounds the bottom shell 1100 along the circumference of the bottom shell 1100, so that the face shell 1200 covers the bottom shell 1100 and seals the opening 1115 of the bottom shell 1100. For example, the bottom shell 1100 includes an open end 1110, which is surrounded by an opening 1115. When the face shell 1200 is assembled to the bottom shell 1100, the first connecting portion 1220 surrounds the open end 1110 (i.e., surrounds the bottom shell 1100). Since the first connecting portion 1220 is protruding from one side of the cover plate 1210, the face shell 1200 covers the open end 1110, thereby covering the opening 1115 and achieving the covering of the face shell 1200 on the bottom shell 1100. Because the first connecting portion 1220 surrounds the bottom shell 1100, the face shell 1200 is limited when moving radially along the opening 1115, thereby preventing a large degree of positional displacement of the face shell 1200 relative to the bottom shell 1100 and facilitating further connection and fixation between the first connecting portion 1220 and the bottom shell 1100.

[0049] In this embodiment, the gas water heater housing structure further includes a sealing strip 1300 , which abuts between the cover plate 1210 and the bottom shell 1100 . During assembly of the front shell 1200 and the bottom shell 1100 , the front shell 1200 and the bottom shell 1100 jointly clamp the sealing strip 1300 , thereby forming a good seal. This is particularly suitable for balanced gas water heaters 1000 , effectively preventing air in the bathroom environment from entering the gas water heater 1000 through the gap between the front shell 1200 and the bottom shell 1100 and consuming oxygen in the bathroom environment. It also effectively prevents carbon monoxide generated during the combustion process of the gas water heater 1000 from entering the bathroom environment through the gap between the front shell 1200 and the bottom shell 1100. It is understood that the sealing strip 1300 can be made of a variety of materials, such as rubber, silicone, thermoplastic elastomer, etc., and this is not limited here. Since the first connecting portion 1220 protrudes from one side of the cover plate 1210 and the sealing strip 1300 abuts between the cover plate 1210 and the bottom shell 1100, that is, a part of the bottom shell 1100 (the open end 1110) is embedded in the surface shell 1200, it is beneficial to compress the space between the surface shell 1200 and the bottom shell 1100 (the space in the front and rear directions), thereby facilitating the gas water heater 1000 to develop towards slimness.

[0050] Combine Figures 3 to 8 as well as Figure 11 、 Figure 12 As shown, in some embodiments, the bottom shell 1100 includes an open end 1110, which is surrounded by an opening 1115. Components can be installed into the bottom shell 1100 through the opening 1115. A groove 1114 is formed on the side of the open end 1110 facing away from the interior of the bottom shell 1100. The first connecting portion 1220 is inserted into the groove 1114, thereby surrounding the open end 1110. When the front shell 1200 covers the open end 1110, the front shell 1200 covers the bottom shell 1100, and a receiving space 1400 is defined between the front shell 1200 and the bottom shell 1100. The first connecting portion 1220 is connected and fixed to the open end 1110, and the sealing strip 1300 abuts between the cover plate 1210 and the open end 1110. The groove 1114 accommodates the first connecting portion 1220 and prevents the first connecting portion 1220 from protruding excessively when surrounding the bottom shell 1100.

[0051] Specifically, as described above, the open end 1110 is the portion that is connected to the face shell 1200. Generally speaking, the open end 1110 is the portion adjacent to the opening 1115 so that the opening 1115 can be enclosed. When the face shell 1200 is assembled to the bottom shell 1100, the first connection portion 1220 surrounds the open end 1110 (that is, the first connection portion 1220 surrounds the bottom shell 1100 at this time). In order to prevent the first connection portion 1220 from protruding too much relative to the outer surface of the bottom shell 1100, a groove 1114 is formed on the side of the open end 1110 facing away from the inside of the bottom shell 1100. The so-called groove 1114 is a groove 1114 that is recessed on the outer surface of the bottom shell 1100 toward the inside of the bottom shell 1100. In other words, the open end 1110 is in a contracted shape relative to other parts of the bottom shell 1100. Figure 4 、 Figure 5 、 Figure 7 and Figure 8 As shown, the front end of the top plate 1102, the front end of the bottom plate 1103, the front end of the left plate 1104 and the front end of the right plate 1105 constitute an opening end 1110, the front end of the top plate 1102 is recessed downward, the front end of the bottom plate 1103 is recessed upward, the front end of the left plate 1104 is recessed to the right, and the front end of the right plate 1105 is recessed to the left. The groove 1114 thus formed extends along the circumference of the bottom shell 1100 and surrounds the opening 1115.

[0052] When the face shell 1200 is assembled to the bottom shell 1100, the first connecting part 1220 is inserted into the groove 1114, so that the first connecting part 1220 surrounds the opening end 1110. It is through the setting of the groove 1114 that the groove 1114 accommodates the first connecting part 1220, avoiding the first connecting part 1220 from protruding too much from the outer surface of the bottom shell 1100, which is beneficial to improving the texture of the product.

[0053] Combine Figures 3 to 8 As shown, in some embodiments, the open end 1110 includes a first mounting portion 1111 and a second mounting portion 1112, the aforementioned groove 1114 is formed between the second mounting portion 1112 and the first mounting portion 1111, the first connecting portion 1220 surrounds the second mounting portion 1112, and the first connecting portion 1220 is connected to the second mounting portion 1112.

[0054] Specifically, the first mounting portion 1111 surrounds the opening 1115, and the second mounting portion 1112 also surrounds the opening 1115. The first mounting portion 1111 protrudes toward the interior of the bottom shell 1100, and the second mounting portion 1112 is arranged on the first mounting portion 1111 and extends from the first mounting portion 1111 toward the cover plate 1210. In this way, a groove 1114 extending along the circumference of the bottom shell 1100 can be formed between the second mounting portion 1112 and the first mounting portion 1111, so that the opening end 1110 is in a contracted shape.

[0055] Continue to combine Figures 3 to 8 As shown, in some embodiments, the face shell 1200 includes a second connecting portion 1230, which is arranged on the first connecting portion 1220, and the second connecting portion 1230 protrudes from the side of the first connecting portion 1220 facing the interior of the bottom shell 1100, and the second connecting portion 1230 is used to abut against the first mounting portion 1111 and / or for abutting against the second mounting portion 1112.

[0056] As can be seen from the above, the groove 1114 is recessed on the outer surface of the bottom shell 1100 and toward the interior of the bottom shell 1100, so that the opening end 1110 is contracted. When the face shell 1200 is assembled to the bottom shell 1100, the first connecting portion 1220 is inserted into the groove 1114 to surround the second mounting portion 1112. In this embodiment, the face shell 1200 also includes a second connecting portion 1230, which is arranged on the first connecting portion 1220. When the first connecting portion 1220 is inserted into the groove 1114, the second connecting portion 1230 is also synchronously inserted into the groove 1114. Since the groove 1114 has a certain depth (along the radial direction of the opening 1115), the second connecting portion 1230 is protruding from the side of the first connecting portion 1220 facing the interior of the bottom shell 1100, so that the second connecting portion 1230 occupies the space in the depth direction of the groove 1114, thereby making the transition between the first connecting portion 1220 and the bottom shell 1100 smoother. At the same time, the second connecting portion 1230 also abuts against the first mounting portion 1111, and the second connecting portion 1230 achieves surface contact with the first mounting portion 1111, thereby reducing the gap here as much as possible.

[0057] Furthermore, the first connecting portion 1220 and the second connecting portion 1230 are formed by bending, which facilitates processing and helps improve structural strength. For example, the cover 1200 is formed from a metal sheet, and the metal sheet is bent at corresponding locations through a stamping process to form the cover plate 1210, the first connecting portion 1220, and the second connecting portion 1230. The cover plate 1210, the first connecting portion 1220, and the second connecting portion 1230 form an integrated structure.

[0058] It is understandable that when assembling the front shell 1200 and the bottom shell 1100, the first connecting portion 1220 and the second connecting portion 1230 need to be inserted into the groove 1114. Since the first connecting portion 1220 and the second connecting portion 1230 are formed by bending, the structural strength of the intersection of the first connecting portion 1220 and the second connecting portion 1230 is strengthened. The second connecting portion 1230 is placed on the first connecting portion 1220 to act as a reinforcing rib, making the first connecting portion 1220 less likely to warp, making the transition between the first connecting portion 1220 and the bottom shell 1100 more seamless. In addition, the second connecting portion 1230 is bent relative to the first connecting portion 1220 and inserted into the groove 1114, thus preventing the exposure of burrs.

[0059] Combine Figures 3 to 8 As shown, in some embodiments, the opening end 1110 includes a third mounting portion 1113, which is arranged on the second mounting portion 1112 and extends along the circumference of the bottom shell 1100 (surrounding the opening 1115), and the third mounting portion 1113 protrudes on the side of the second mounting portion 1112 facing the interior of the bottom shell 1100, and the sealing strip 1300 abuts between the third mounting portion 1113 and the cover plate 1210.

[0060] Specifically, by providing the sealing strip 1300, sealing between the face shell 1200 and the bottom shell 1100 can be achieved. Since the sealing strip 1300 is sealed under the extrusion of the face shell 1200 and the bottom shell 1100, in this embodiment, a relatively large contact area can be achieved between the cover plate 1210 and the sealing strip 1300. By providing the third mounting portion 1113, and the third mounting portion 1113 protruding from the side of the second mounting portion 1112 facing the interior of the bottom shell 1100, a relatively large contact area can be achieved between the sealing strip 1300 and the third mounting portion 1113. Under the extrusion of the face shell 1200 and the bottom shell 1100, the sealing strip 1300 is not prone to excessive deformation or even breakage, thereby avoiding premature aging.

[0061] Furthermore, the first mounting portion 1111, the second mounting portion 1112, and the third mounting portion 1113 are formed by bending, which facilitates processing and helps improve structural strength. For example, corresponding portions of the top plate 1102, the bottom plate 1103, the left plate 1104, and the right plate 1105 are stamped to achieve bending of the corresponding portions, thereby forming the first mounting portion 1111, the second mounting portion 1112, and the third mounting portion 1113 of the bottom shell 1100.

[0062] The first connecting part 1220 and the bottom shell 1100 need to be connected to each other to achieve the fastening between the face shell 1200 and the bottom shell 1100. There are many ways of connection, such as threaded connection, clamping, welding, riveting, etc. In some embodiments, the connection between the first connecting part 1220 and the bottom shell 1100 is carried out in a threaded connection manner, that is, the first connecting part 1220 and the bottom shell 1100 are respectively provided with fastening holes, and the fastening holes of the bottom shell 1100 can be set in the second mounting part 1112 or adjacent to the second mounting part 1112, and the screws pass through the fastening holes of the first connecting part 1220 and the fastening holes of the bottom shell 1100 to achieve a fastened connection. Through the threaded connection, the connection and fastening between the face shell 1200 and the bottom shell 1100 can be achieved, and the face shell 1200 and the bottom shell 1100 can also be disassembled when needed to facilitate maintenance.

[0063] In some embodiments, the connection between the first connection part 1220 and the bottom shell 1100 is arranged at the top and bottom of the gas water heater outer shell structure. For example, the fastening holes of the first connection part 1220 are arranged at the top and bottom of the surface shell 1200, and the fastening holes of the bottom shell 1100 are arranged at the top and bottom of the bottom shell 1100.

[0064] Specifically, the second mounting portion 1112 is arranged along the circumferential extension of the bottom shell 1100, and the first connecting portion 1220 is arranged along the circumferential extension of the face shell 1200. When the face shell 1200 is assembled to the bottom shell 1100, the first connecting portion 1220 surrounds the second mounting portion 1112. By surrounding the second mounting portion 1112 with the first connecting portion 1220, the face shell 1200 is limited when moving radially along the opening 1115, but the face shell 1200 will still detach from the bottom shell 1100 along the axial direction of the opening 1115. For this reason, the first connecting portion 1220 is further connected to the bottom shell 1100 to achieve the fastening of the face shell 1200 and the bottom shell 1100.

[0065] In this embodiment, the connections between the first connection portion 1220 and the bottom housing 1100 are located at the top and bottom of the gas water heater's housing structure, making them difficult for users to see. This creates a visual effect of "no connection," which helps enhance the product's quality. It is understandable that after the gas water heater 1000 is installed in its intended use environment, the top of the gas water heater 1000 is located at a high position, making it difficult for users to see the top of the gas water heater 1000 and, consequently, the connection at the top of the gas water heater's housing structure (the connection between the first connection portion 1220 and the bottom housing 1100) difficult to see. While the bottom of the gas water heater 1000 is easily visible to users, components such as the water inlet pipe, drain pipe, and gas pipe are located at the bottom of the gas water heater 1000. These pipes obscure the connection at the bottom of the water heater's housing structure (the connection between the first connection portion 1220 and the bottom housing 1100), making it difficult for users to see the connection at the bottom of the water heater's housing structure (the connection between the first connection portion 1220 and the bottom housing 1100).

[0066] In some embodiments, combined Figure 9 and Figure 10 As shown, the sealing strip 1300 is bonded and fixed to the cover plate 1210, making assembly more convenient. Specifically, when assembling the front shell 1200 and the bottom shell 1100, it is generally necessary to fix the bottom shell 1100 to a workbench and then move the front shell 1200 to assemble it onto the bottom shell 1100. If the sealing strip 1300 is placed on the bottom shell 1100 and then assembled with the front shell 1200, the sealing strip 1300 is likely to change position and thus cannot be properly abutted between the front shell 1200 and the bottom shell 1100. To this end, in this embodiment, the sealing strip 1300 is adhered to the cover plate 1210, and the sealing strip 1300 is fixed relative to the cover plate 1210. When the face shell 1200 is assembled to the bottom shell 1100, the sealing strip 1300 moves with the face shell 1200. After the face shell 1200 is assembled into place, it abuts between the face shell 1200 and the bottom shell 1100, so that the sealing strip 1300 better cooperates with the face shell 1200 and the bottom shell 1100, which is conducive to improving assembly efficiency.

[0067] Combine Figure 13As shown, in some embodiments, the bottom shell 1100 includes a top plate 1102, a bottom plate 1103, a left plate 1104, a right plate 1105 and a back plate 1101. The bottom plate 1103 and the back plate 1101 are integrally formed and bent to each other, the left plate 1104, the right plate 1105 and the top plate 1102 are integrally formed and bent to each other, the back plate 1101 is respectively connected to the left plate 1104, the right plate 1105 and the top plate 1102, and the bottom plate 1103 is respectively connected to the left plate 1104 and the right plate 1105. Through such an arrangement, the existence of gaps is reduced, which is conducive to further improving the sealing performance, and is particularly suitable for balanced gas water heaters 1000.

[0068] For example, the back panel 1101 and the bottom panel 1103 are formed by bending the same metal sheet through a stamping process, and the top panel 1102, the left side panel 1104 and the right side panel 1105 are formed by bending the same metal sheet through a stamping process. The left side of the back panel 1101 is connected to the rear side of the left side panel 1104, the right side of the back panel 1101 is connected to the rear side of the right side panel 1105, the upper side of the back panel 1101 is connected to the rear side of the top panel 1102, the left side of the bottom panel 1103 is connected to the lower side of the left side panel 1104, and the right side of the bottom panel 1103 is connected to the lower side of the right side panel 1105. The connection method can be welding and / or riveting, or other methods can be used for connection and fixation. Since the back panel 1101 and the bottom panel 1103 are integrally formed, and the top panel 1102, the left side panel 1104 and the right side panel 1105 are integrally formed, this helps to reduce the existence of gaps in the bottom shell 1100. In particular, by providing a covering layer on the inner surface and / or outer surface of the bottom shell 1100, the covering layer can cover the gaps in the bottom shell 1100, thereby greatly improving the sealing performance. It can be understood that the covering layer is a layer of covering covering the surface of the component, and the material of the covering layer is not limited, for example, the covering layer is formed by powder coating.

[0069] The second aspect of the present invention discloses a gas water heater 1000, Figures 1 to 13As shown, the gas water heater 1000 includes the above-mentioned gas water heater shell structure, and the gas water heater shell structure includes a bottom shell 1100, a surface shell 1200 and a sealing strip 1300. The surface shell 1200 includes a cover plate 1210 and a first connecting portion 1220. The first connecting portion 1220 is arranged on the periphery of the cover plate 1210, and the first connecting portion 1220 protrudes from one side of the cover plate 1210. The first connecting portion 1220 surrounds the bottom shell 1100 and is connected to the bottom shell 1100, so that the surface shell 1200 covers the bottom shell 1100, thereby enclosing a accommodating space 1400 between the surface shell 1200 and the bottom shell 1100, and the sealing strip 1300 abuts between the cover plate 1210 and the bottom shell 1100, so that a seal is formed between the surface shell 1200 and the bottom shell 1100. In this embodiment, the face shell 1200 includes a cover plate 1210 and a first connecting portion 1220. When the face shell 1200 and the bottom shell 1100 are assembled, the first connecting portion 1220 surrounds the bottom shell 1100, thereby forming a limit for the face shell 1200, so that the face shell 1200 can better cooperate with the bottom shell 1100, and the face shell 1200 is not easily displaced relative to the bottom shell 1100, thereby further connecting and fixing the face shell 1200 and the bottom shell 1100. In addition, by arranging a sealing strip 1300 between the cover plate 1210 and the bottom shell 1100, the cover plate 1210 and the bottom shell 1100 jointly clamp the sealing strip 1300, thereby enhancing the sealing effect between the face shell 1200 and the bottom shell 1100.

[0070] The outer shell structure of the gas water heater includes a bottom shell 1100, which has an opening 1115. Some components of the water heater are installed in the bottom shell 1100 through the opening 1115. The surface shell 1200 is assembled to the bottom shell 1100 to cover the bottom shell 1100, that is, the surface shell 1200 covers the opening 1115 of the bottom shell 1100, so that an accommodating space 1400 is enclosed between the surface shell 1200 and the bottom shell 1100, and some of the aforementioned components are located in the accommodating space 1400.

[0071] For example, taking the gas water heater 1000 as a reference when it is installed in the use environment, the user stands facing the gas water heater 1000, the side of the gas water heater 1000 facing the user is the front, the side away from the user is the back, the side corresponding to the user's left hand is the left, the side corresponding to the user's right hand is the right, the side close to the ground is the bottom (bottom), and the side away from the ground is the top (top). The bottom shell 1100 includes a back plate 1101, a top plate 1102, a bottom plate 1103, a left side plate 1104 and a right side plate 1105. The top plate 1102 is set on the top of the back plate 1101. The bottom plate 1103 is set at the bottom end of the back plate 1101, the left side plate 1104 is set on the left side of the back plate 1101, and the right side plate 1105 is set on the right side of the back plate 1101. The top plate 1102, the bottom plate 1103, the left side plate 1104 and the right side plate 1105 are surrounded by an opening 1115. The face shell 1200 is set on the front side of the back plate 1101 and is connected to the top plate 1102, the bottom plate 1103, the left side plate 1104 and the right side plate 1105, so that the face shell 1200 covers the bottom shell 1100 to seal the opening 1115 of the bottom shell 1100.

[0072] The cover 1200 includes a cover plate 1210 and a first connecting portion 1220. The cover plate 1210 is flat as a whole. Of course, the cover plate 1210 can be designed into other shapes according to actual needs. The first connecting portion 1220 is arranged on the periphery of the cover plate 1210. The first connecting portion 1220 extends along the circumference of the cover plate 1210, and the first connecting portion 1220 is protruded on one side of the cover plate 1210. Figure 3 、 Figure 4 and Figure 5 As shown, the bottom shell 1100 is located behind the face shell 1200, and the first connecting portion 1220 protrudes toward the rear on the rear side of the cover plate 1210. When the face shell 1200 is assembled to the bottom shell 1100, the first connecting portion 1220 surrounds the bottom shell 1100, that is, the first connecting portion 1220 surrounds the bottom shell 1100 along the circumference of the bottom shell 1100, so that the face shell 1200 covers the bottom shell 1100 and seals the opening 1115 of the bottom shell 1100. For example, the bottom shell 1100 includes an open end 1110, which is surrounded by an opening 1115. When the face shell 1200 is assembled to the bottom shell 1100, the first connecting portion 1220 surrounds the open end 1110 (i.e., surrounds the bottom shell 1100). Since the first connecting portion 1220 is protruding from one side of the cover plate 1210, the face shell 1200 covers the open end 1110, thereby covering the opening 1115 and achieving the covering of the face shell 1200 on the bottom shell 1100. Because the first connecting portion 1220 surrounds the bottom shell 1100, the face shell 1200 is limited when moving radially along the opening 1115, thereby preventing a large degree of positional displacement of the face shell 1200 relative to the bottom shell 1100 and facilitating further connection and fixation between the first connecting portion 1220 and the bottom shell 1100.

[0073] In this embodiment, the gas water heater housing structure further includes a sealing strip 1300 , which abuts between the cover plate 1210 and the bottom shell 1100 . During assembly of the front shell 1200 and the bottom shell 1100 , the front shell 1200 and the bottom shell 1100 jointly clamp the sealing strip 1300 , thereby forming a good seal. This is particularly suitable for balanced gas water heaters 1000 , effectively preventing air in the bathroom environment from entering the gas water heater 1000 through the gap between the front shell 1200 and the bottom shell 1100 and consuming oxygen in the bathroom environment. It also effectively prevents carbon monoxide generated during the combustion process of the gas water heater 1000 from entering the bathroom environment through the gap between the front shell 1200 and the bottom shell 1100. It is understood that the sealing strip 1300 can be made of a variety of materials, such as rubber, silicone, thermoplastic elastomer, etc., and this is not limited here. Since the first connecting portion 1220 protrudes from one side of the cover plate 1210 and the sealing strip 1300 abuts between the cover plate 1210 and the bottom shell 1100, that is, a part of the bottom shell 1100 (the open end 1110) is embedded in the surface shell 1200, it is beneficial to compress the space between the surface shell 1200 and the bottom shell 1100 (the space in the front and rear directions), thereby facilitating the gas water heater 1000 to develop towards slimness.

[0074] It can be understood that the gas water heater 1000 includes the gas water heater shell structure of the above embodiment. The gas water heater shell structure of this embodiment adopts the technical solution of the above embodiment, and therefore has at least the beneficial effects brought by the technical solution of the above embodiment, which will not be repeated here.

[0075] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention description and drawings under the concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
