[0033] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0034] In one embodiment, a gas water heater is provided, comprising a combustion device and a shell structure 10, wherein the combustion device is installed in the shell structure 10. Thus, the combustion device can be installed on a wall through the shell structure 10, thereby improving the practicality of the gas water heater.

[0035] The combustion device may be any existing combustion structure, which will not be described in detail here.

[0036] As shown in Figures 1, 2 and 3, in one embodiment, a shell structure 10 is provided, which includes a bottom shell 100 and a vibration damping assembly 200, wherein the vibration damping assembly 200 is installed on the outer wall of the bottom shell 100, and the vibration damping assembly 200 includes a mounting member 210 and an elastic member 230, wherein the elastic member 230 is connected between the mounting member 210 and the outer wall of the bottom shell 100, and the mounting member 210 protrudes from the outer wall of the bottom shell 100.

[0037] When the shell structure 10 in the above embodiment is used, the shell structure 10 is correspondingly mounted on the wall, so that the vibration reduction assembly 200 is in contact with the wall, and the bottom shell 100 is spaced from the wall. When the water heater is working, the elastic member 230 is located between the bottom shell 100 and the mounting member 210, so that the vibration reduction assembly 200 can play a role in buffering and reducing noise propagation, thereby reducing the vibration of the wall, reducing the noise emitted by the gas water heater, and improving the comfort of using the gas water heater. In addition, the vibration reduction assembly 200 is located between the bottom shell 100 and the wall, so that the bottom shell 100 does not directly contact the wall, which can effectively prevent the vibration of the bottom shell 100 from damaging the wall, thereby improving the reliability of the shell structure 10.

[0038] The vibration reduction assembly 200 may be installed on the outer wall of the bottom shell 100 by snapping, bonding, screwing, hooking, riveting or other connection methods.

[0039] Specifically in this embodiment, the bottom shell 100 is set as a bottom plate, and the shell structure 10 also includes two side plates, which are correspondingly connected to the two sides opposite to the bottom plate. The bottom plate is provided with a convex bump 113, and the convex bump 113 is provided with at least one connecting hole 114, and the connecting hole 114 is used to install the bottom shell 100 on the wall.

[0040] Optionally, there are at least two vibration reduction assemblies 200, each of which is disposed at intervals on the outer wall of the bottom shell 100. In this way, by increasing the number of vibration reduction assemblies 200, the buffering effect is further enhanced, the vibration of the wall is reduced, the noise is reduced, and the comfort of using the gas water heater is improved.

[0041] Specifically in this embodiment, four vibration reduction components 200 are provided, and the four vibration reduction components 200 are correspondingly installed at the four corners of the bottom shell 100. In this way, the bottom shell 100 can be installed flatly on the wall through the four vibration reduction components 200.

[0042] As shown in FIG. 2 , FIG. 3 and FIG. 4 , in one embodiment, the outer wall of the bottom shell 100 is provided with a mounting hole 111, and the mounting member 210 is provided with a connecting portion 220, and the connecting portion 220 passes through the mounting hole 111 and overlaps with the inner wall of the bottom shell 100; the elastic member 230 is sleeved on the connecting portion 220, and the mounting member 210 can approach the bottom shell 100 along the axis direction of the mounting hole 111, and the elastic member 230 is used to provide the mounting member 210 with an elastic force in a direction away from the bottom shell 100 (as shown in the direction D in FIG. 3 ). In this way, the mounting member 210 can be buckled on the bottom shell 100 through the connecting portion 220 and the mounting hole 111, and the elastic member 230 is between the mounting member 210 and the bottom shell 100 and is compressed, so that the connecting portion 220 and the inner wall of the bottom shell 100 are kept buckled, and the elastic member 230 supports the mounting member 210 to bulge, ensuring that the vibration reduction assembly 200 has the function of vibration reduction and noise reduction, and improving the reliability of the shell structure 10.

[0043] Among them, the elastic member 230 can be set as an elastic pad, an elastic sleeve, a spring or other elastic structure. The number of the elastic members 230 can be flexibly adjusted according to the actual needs of use. Specifically in this embodiment, the elastic member 230 is set as a spring, and there is one spring. The spring is sleeved on the outer wall of the connecting portion 220, and the two ends of the spring are respectively fixedly connected to the outer wall of the mounting member 210 and the bottom shell 100. In other embodiments, the elastic member 230 may not be sleeved on the outer side of the connecting portion 220. For example, there are at least two elastic members 230, and each elastic member 230 is spaced around the axis of the connecting portion 220.

[0044] As shown in Fig. 3 and Fig. 4, the connection part 220 further includes two elastic buckles 221, which are symmetrically arranged and respectively snapped on opposite sides of the mounting hole 111. In this way, by increasing the number of elastic buckles 221, the contact area between the connection part 220 and the shell is increased, which effectively prevents the connection part 220 from coming out of the mounting hole 111 and causing the vibration reduction assembly 200 to be separated from the bottom shell 100, thereby improving the reliability of the shell structure 10.

[0045] Specifically in this embodiment, the mounting member 210 and the connecting portion 220 can be made of plastic material in one piece.

[0046] As shown in FIG3 and FIG4 , optionally, the two elastic buckles 221 each include an elastic arm 2211 and a clamping block 2212, the elastic arm 2211 is connected to the mounting member 210, the distance between the two elastic arms 2211 gradually increases toward the bottom shell 100 (as shown in the direction E in FIG3 ), and the elastic arm 2211 passes through the mounting hole 111. The elastic member 230 is sleeved on the elastic arm 2211, the clamping block 2212 is arranged at one end of the elastic arm 2211 away from the mounting member 210, and the clamping block 2212 overlaps the inner side wall of the bottom shell 100. In this way, when the two elastic arms 2211 are in a squeezed state, the distance between the two blocks 2212 is reduced, so that the elastic buckle 221 can be inserted into the mounting hole 111, and the elastic member 230 is compressed; when the two elastic arms 2211 are in a reset state, the elastic arms 2211 respectively contact the two side walls opposite to the mounting hole 111, and the distance between the two blocks 2212 is increased so that they can contact and limit with the inner side wall of the bottom shell 100, and the elastic member 230 releases the elastic force, ensuring that the mounting member 210 can be buckled on the bottom shell 100 through the elastic buckle 221 and the elastic member 230, thereby improving the reliability and convenience of the shell structure 10. In addition, the vibration reduction assembly 200 and the bottom shell 100 are detachable, which improves the convenience of maintenance and replacement of the shell structure 10.

[0047] As shown in Fig. 5, Fig. 6 and Fig. 7, in one embodiment, the outer wall of the bottom shell 100 is provided with an annular boss 112, the mounting hole 111 is located in the annular boss 112, and the mounting member 210 and the annular boss 112 are slidably matched along the axial direction of the annular boss 112. In this way, the annular boss 112 can play a role of limiting and guiding the mounting member 210, ensuring that the mounting member 210 can move relative to the bottom shell 100 along the axial direction of the annular boss 112 to squeeze the elastic member 230 for vibration reduction, thereby improving the reliability of the housing structure 10.

[0048] As shown in Fig. 4, Fig. 5 and Fig. 7, optionally, a second mounting groove 213 is provided on one side of the mounting member 210 close to the bottom shell 100, and an elastic buckle 221 is provided on the bottom wall of the second mounting groove 213. In this way, the elastic buckle 221 is partially hidden in the second mounting groove 213, so that the thickness of the housing structure 10 is reduced to improve the practicality of the housing structure 10, and the mounting member 210 can also protect the elastic buckle 221, thereby improving the reliability and service life of the housing structure 10.

[0049] Specifically in this embodiment, the annular boss 112 is provided in a circular ring shape. The mounting hole 111 is provided in a square hole, and the central axis of the mounting hole 111 and the central axis of the annular boss 112 are located on the same straight line. The contour of the outer wall of the mounting member 210 is adapted to the contour of the inner wall of the annular boss 112. In other embodiments, the contour of the inner wall of the second mounting groove 213 may also be adapted to the contour of the outer wall of the annular boss 112.

[0050] As shown in Fig. 3, Fig. 4 and Fig. 5, in one embodiment, the vibration reduction assembly 200 further includes a vibration reduction member 240, which is disposed on a side of the mounting member 210 away from the bottom shell 100. In this way, the vibration reduction member 240 and the elastic member 230 can both play a role in vibration reduction and noise reduction, thereby increasing the vibration reduction and noise reduction effect of the shell structure 10 and improving the comfort of using the combustion gas water heater.

[0051] As shown in Fig. 3, Fig. 4 and Fig. 5, further, a first mounting groove 211 is provided on a side of the mounting member 210 away from the bottom shell 100, and the vibration damping member 240 is mounted in the first mounting groove 211. In this way, the first mounting groove 211 can play a role in positioning and limiting, so that the vibration damping member 240 can be quickly and accurately installed at a designated position on the mounting member 210, thereby improving the convenience of assembling the housing structure 10.

[0052] The vibration damping member 240 can be configured as a rubber pad 241, a sponge pad or other vibration damping structure. The vibration damping member 240 can be installed in the first mounting groove 211 by means of snap connection, screw connection, bonding or other fixed connection. The mounting member 210 can be configured as a mounting seat, a mounting bracket or other mounting structure. Specifically in this embodiment, the vibration damping member 240 is configured as a rubber pad 241, and the rubber pad 241 is bonded and fixed to the mounting member 210.

[0053] Specifically, the rubber pad 241 is fixed to the inner wall of the first mounting groove 211 by adhesive backing. Thus, when the vibration reduction assembly 200 is assembled, the backing adhesive is applied to the back of the rubber pad 241, and then the rubber pad 241 is installed at the first mounting groove 211, so that the backing adhesive is in contact with the bottom wall of the first mounting groove 211 and is fastened.

[0054] As shown in Fig. 3, Fig. 4 and Fig. 5, optionally, the bottom wall of the first mounting groove 211 is provided with an exhaust hole 212. In this way, during the installation of the rubber pad 241, the air in the first mounting groove 211 can be discharged through the exhaust hole 212, ensuring that the rubber pad 241 can be stably and reliably bonded to the mounting member 210, thereby improving the reliability of the housing structure 10.

[0055] Specifically in this embodiment, there are at least two exhaust holes 212, and each exhaust hole 212 is arranged at intervals around the central axis of the first installation groove 211. In this way, it is ensured that the air in the first installation groove 211 can be completely discharged, and then it is ensured that the rubber pad 241 can be stably and reliably bonded to the bottom wall of the first installation groove 211, thereby improving the reliability of the housing structure 10.
