[0037] In the description of the present utility model, unless otherwise clearly defined, terms such as "set", "installed", "connected", etc. should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above terms in the present utility model in combination with the specific content of the technical solution.

[0038] Currently, the mounting brackets of some water heaters are directly welded to the bottom of the casing. To ensure the stability of the support of the mounting brackets, the mounting brackets are generally made of sheet metal materials with a relatively large thickness, which increases the overall machine load. In addition, the mounting brackets made of sheet metal materials are limited in terms of vibration isolation. During the operation of the water heater, resonance will occur between the water heater and the mounting brackets, resulting in loosening of the screws and abnormal sounds in the wall, generating noise.

[0039] In the related art, some water heaters adopt a scheme of separating the body from the mounting bracket. Although this scheme can relatively reduce the overall weight of the machine, it cannot solve the problem of resonance between the body and the mounting bracket during the operation of the water heater; in addition, some water heaters add vibration damping pads between the body and the mounting bracket, but the fixing of the vibration damping pads is not stable and cannot achieve an ideal vibration damping effect.

[0040] An embodiment of the present utility model provides a chassis assembly, which is applied to a water heater. Hereinafter, taking the water heater as an example and in combination with the text and drawings, the specific structure and function of the chassis assembly provided by the embodiment of the present utility model will be further described.

[0041] It should be noted that when the chassis assembly is applied to a water heater, the water heater and the mounting bracket are of a split structure and can be transported separately. The water heater is connected to the mounting bracket through a vibration damping assembly 300, so that it can be fixed on the mounting bracket.

[0042] Refer to Figure 2 and Figure 3 , the chassis assembly according to the first aspect embodiment of the present utility model includes: a support plate 100 and a water receiving plate 200. The water receiving plate 200 is arranged below the support plate 100 and connected to the support plate 100. The support plate 100 can bear the downward pressure of the components installed on its upper end surface, and bear the downward pulling force of the water receiving plate 200 located below it, which can ensure the structural stability of the chassis assembly.

[0043] It can be understood that the support plate 100 is provided with water passing holes communicating with the water receiving tray 200, and a drain port 230 is provided in the middle of the water receiving tray 200. When the chassis assembly is applied to a water heater, the water receiving tray 200 can collect the water droplets generated during the operation of the water heater, and the collected water droplets can be discharged through the drain port 230, preventing them from directly dripping onto the ground, thereby keeping the surrounding environment dry and clean. In addition, the water receiving tray 200 can also collect and discharge the rainwater that may accumulate around the outer shell of the water heater in rainy days or humid environments, preventing the accumulated water from causing damage to the water heater or affecting its normal operation.

[0044] Refer to Figure 2 and Figure 3 , in some embodiments, the water receiving tray 200 is generally square, and a plurality of vibration damping components 300 are provided at its bottom. The plurality of vibration damping components 300 are arranged at intervals along the four sides of the bottom of the water receiving tray 200. The cooperation of the plurality of vibration damping components 300 can support the chassis assembly, avoiding the scenario where the mounting bracket is directly welded to the bottom of the water heater, effectively reducing the overall weight; and, the vibration damping member 330 can effectively absorb the vibration generated during the operation of the machine body, and can avoid the resonance between the water heater and the mounting bracket, resulting in the phenomenon of screw loosening and wall abnormal noise.

[0045] It can be understood that the number of the vibration damping components 300 can be 4, 6, etc., and the number of the vibration damping components 300 can meet the condition of stably supporting the water heater; for example, in some embodiments, the chassis assembly is generally square, and the number of the vibration damping components 300 is 4, and the 4 vibration damping components 300 are respectively arranged at the 4 corners of the chassis assembly, so as to realize the support of the chassis assembly.

[0046] Refer to Figure 3 and Figure 4, in some embodiments, the damping assembly 300 includes a fixing member 310, a connecting member 320, and a damping member 330. The fixing member 310 is generally cylindrical and its upper end is fixed to the support plate 100. The connecting member 320 is columnar and located below the water receiving tray 200. The radius of the upper end of the connecting member 320 is smaller than that of the lower end, so as to form a stepped surface on the upper part of the connecting member 320. The water receiving tray 200 is provided with a perforation communicating with the fixing member 310. The width of the perforation is slightly larger than the width of the upper end of the connecting member 320, but smaller than the width of the stepped surface of the connecting member 320. The upper end of the connecting member 320 passes through the through hole on the water receiving tray 200 and is connected to the fixing member 310. The stepped surface on the upper part of the connecting member 320 abuts against the lower end surface of the water receiving tray 200, so that the support plate 100 and the water receiving tray 200 can be connected as a whole, ensuring the stability of the connection between the support plate 100 and the water receiving tray 200. The damping member 330 is connected to the lower end of the connecting member 320. Multiple damping members 330 cooperate to support the chassis assembly and the entire water heater, so that the water heater and the mounting bracket can be a split structure, and thus can be transported or installed separately, avoiding the situation where the mounting bracket is directly welded to the water heater, effectively reducing the overall weight. And, the damping member 330 can effectively absorb the vibration generated during the operation of the machine body, and can avoid the resonance between the water heater and the mounting bracket, resulting in the loosening of the screws and abnormal noise of the wall, reducing the noise during operation.

[0047] It can be understood that the fixing member 310 can be fixed to the support plate 100 by welding or riveting. After the damping member 330 is connected to the fixing member 310, it is equivalent to being directly fixed to the support plate 100, and the connection between the damping member 330 and the support plate 100 is firm. In addition, as the main load-bearing component in the chassis assembly, the damping assembly 300 is fixed to the support plate 100 through the fixing member 310 and the connecting member 320, which can ensure the reliability of the connection between the damping assembly 300 and the chassis assembly. And, the pressure borne by the support plate 100 can be directly transmitted to the damping member 330 through the fixing member 310 and the connecting member 320, which can avoid the phenomenon that the water receiving tray 200 is deformed by pressure. In addition, the vibration of the support plate 100 can also be directly transmitted to the damping member 330 through the fixing member 310 and the connecting member 320, which can ensure that the damping member 330 can weaken the vibration to a large extent and reduce the noise.

[0048] It can be understood that the bottom of the damping member 330 is provided with a connection hole 339, and the damping member 330 and the mounting bracket can be connected by screws.

[0049] Refer to Figures 3 to 5, in some embodiments, the overall shape of the vibration damping member 330 is cylindrical. The vibration damping member 330 includes a connecting portion 331, a vibration damping portion 332, and a supporting portion 333. Among them, the connecting portion 331 and the supporting portion 333 are made of a firm material, such as plastic, metal, etc., so as to ensure the stability of the structures of the connecting portion 331 and the supporting portion 333 themselves; the vibration damping portion 332 is made of a flexible material, such as rubber, silica gel, etc., so that the vibration damping portion 332 can better absorb vibrations; the connecting hole 339 at the bottom of the vibration damping member 330 is located on the vibration damping portion 332, thus facilitating the connection between the vibration damping member 330 and the mounting bracket; the connecting portion 331, the vibration damping portion 332, and the supporting portion 333 are arranged in sequence from top to bottom. The upper end surface of the connecting portion 331 is a plane, and a stud 334 extending upward is provided in the middle of this plane. The connecting member 320 is a connecting column, and the lower end of the connecting column is recessed to form a threaded hole 321 extending upward. The stud 334 passes through the threaded hole 321 and is threadedly connected to the threaded hole 321, so that the vibration damping member 330 can be fixed on the connecting member 320, and the connection between the vibration damping member 330 and the connecting member 320 is stable and reliable.

[0050] It can be understood that during installation, align the stud 334 at the upper end of the vibration damping member 330 with the threaded hole 321 at the lower end of the connecting member 320, and then rotate the vibration damping member 330 so that the stud 334 is screwed into the threaded hole 321 to fix the vibration damping member 330 on the connecting member 320. The installation method is simple and reliable.

[0051] It should be noted that during the installation process, due to different installation conditions in different environments, the mounting bracket cannot be adjusted horizontally. However, in the embodiments of the present invention, the distance that the stud 334 is screwed into the threaded hole 321 can be controlled by rotating the vibration damping member 330, so as to control the distance between the bottom of the vibration damping member 330 and the water receiving tray 200. Multiple vibration damping members 330 can cooperate to adjust the levelness of the chassis assembly to a certain extent, so that the chassis assembly installed can ensure horizontal.

[0052] Refer to Figure 4 and Figure 5, in some embodiments, the connecting portion 331 is generally cylindrical with both the upper end face and the lower end face being flat. In the middle of the upper end face of the connecting portion 331, there is a stud 334 connected to the connecting member 320, and on the lower end face, there is a first boss 335 extending downward. The first boss 335 is generally cylindrical, and its diameter is smaller than that of the connecting portion 331; a stepped surface is formed between the connecting portion 331 and the first boss 335. The upper end face of the damping portion 332 is concave to form a first clamping groove 336. The first clamping groove 336 is generally a circular stepped groove. The diameter of the lower end of the first clamping groove 336 matches the diameter of the first boss 335, and the diameter of the upper end matches the diameter of the connecting portion 331. The first boss 335 is snapped into the first clamping groove 336, and the outer wall of the first boss 335 is in close contact with the inner wall of the first clamping groove 336, thereby increasing the connection stability between the connecting portion 331 and the damping portion 332.

[0053] It should be noted that the shape of the first boss 335 can also be a triangular prism, a prism, etc. The specific shape of the first boss 335 can be set according to actual needs as long as the condition of stable connection between the connecting portion 331 and the damping portion 332 is satisfied.

[0054] Refer to Figure 4 and Figure 5 , in some embodiments, the lower end face of the damping portion 332 is concave upward to form a second clamping groove 338. The second clamping groove 338 is a stepped groove. The support portion 333 is generally cylindrical. On the upper end face of the support portion 333, there is a second boss 337 extending upward. The second boss 337 is also generally cylindrical, and its diameter is smaller than that of the support portion 333; the diameter of the upper end of the second clamping groove 338 matches the diameter of the second boss 337, and the diameter of the lower end matches the diameter of the support portion 333. The second boss 337 is snapped into the second clamping groove 338, and the outer wall of the second boss 337 is in close contact with the inner wall of the second clamping groove 338, thereby increasing the connection stability between the support portion 333 and the damping portion 332.

[0055] It should be noted that the shape of the second boss 337 can also be a triangular prism, a prism, etc. The specific shape of the second boss 337 can be set according to actual needs as long as the condition of stable connection between the support portion 333 and the damping portion 332 is satisfied.

[0056] Refer to Figure 5 , in some embodiments, the connecting portion 331 and the support portion 333 are metal parts, and the damping portion 332 is a rubber part. The connecting portion 331, the damping portion 332, and the support portion 333 are integrally injection-molded. The connecting portion 331, the damping portion 332, and the support portion 333 can form an integral structure, which can not only ensure the reliability of the connection between the connecting portion 331, the damping portion 332, and the support portion 333, but also reduce the production cost.

[0057] It can be understood that the connecting portion 331 of the shock absorber 330 is a metal part, and the stud 334 on its upper end surface is in close fit with the connecting member 320, which can achieve high-strength fixation between the shock absorber 330 and the connecting member 320, and can ensure that the shock absorber 330 is not easily loosened or separated when subjected to external forces during transportation or installation; in addition, the connecting portion 331 can also better transmit the vibration of the chassis assembly to the shock-absorbing portion 332, so that the shock-absorbing portion 332 can better absorb the vibration generated during the operation of the water heater. The shock-absorbing portion 332 of the shock absorber 330 is a rubber part, and the elastic deformation of the rubber part can absorb and disperse the vibration energy transmitted from the connecting portion 331, effectively reducing the transmission of vibration and achieving better shock absorption and noise reduction effects. In addition, since the water heater is exposed to the external environment all year round, its working environment is relatively harsh, and the rubber part can meet the use requirements due to its wear resistance, corrosion resistance and aging resistance; the supporting portion 333 of the shock absorber 330 is a metal part. As the part connecting the shock absorber 330 and the mounting bracket, the fact that it is a metal part can achieve high-strength fixation between the shock absorber 330 and the mounting bracket, and can minimize the influence of the vibration during the operation of the water heater on the connection stability between the shock absorber 330 and the mounting bracket.

[0058] Referring to Figure 3 and Figure 4 , in some embodiments, the bottom of the water receiving tray 200 is recessed upward at multiple places, so as to form a plurality of receiving grooves 210 at the bottom of the water receiving tray 200. The number of the receiving grooves 210 corresponds one-to-one to the number of the shock absorber assemblies 300; the connecting member 320 is located in the receiving groove 210; the radius of the upper end of the connecting member 320 is smaller than the radius of the lower end, so as to form a stepped surface at the upper part of the connecting member 320; a through hole penetrating the water receiving tray 200 and communicating with the fixing member 310 is provided on the bottom wall of the receiving groove 210 at the bottom of the water receiving tray 200. The width of the through hole is slightly larger than the width of the upper end of the connecting member 320, but smaller than the width of the stepped surface of the connecting member 320; the upper end of the connecting member 320 passes through the through hole on the water receiving tray 200 and is connected to the fixing member 310, and the stepped surface at the upper part of the connecting member 320 abuts against the bottom wall of the receiving groove 210, so that the water receiving tray 200 can be connected to the water receiving tray 200 as a whole; the lower end of the connecting member 320 is located in the receiving groove 210 or flush with the bottom of the water receiving tray 200, which can avoid the phenomenon that the water receiving tray cannot be leveled during installation due to the connecting member 320 protruding from the bottom of the water receiving tray 200.

[0059] It can be understood that at the position where the lower end surface of the water receiving tray 200 is recessed upward, a connecting boss 220 is formed on the upper end surface of the water receiving tray 200. After the upper end of the connecting member 320 is connected to the fixing member 310, the upper end of the connecting boss 220 is pressed against the bottom of the support tray 100, and the pre-tightening force between the connecting member 320 and the fixing member 310 can fix the water receiving tray 200 below the support tray 100.

[0060] Referring to Figure 1 and Figure 2 In some embodiments, the support disk 100 is a metal disk. The metal disk generally has high strength and rigidity, and can bear the weight of the water heater itself and various pressures brought by the external environment, such as wind force, vibration, etc., to ensure the stable operation of the outdoor unit. In addition, the metal disk also has good anti-vibration performance and can better receive the vibration generated during the operation of the water heater.

[0061] Referring to Figure 4 and Figure 5 In some embodiments, the fixing member 310 is cylindrical and made of a metal material. The upper end of the fixing member 310 is fixedly connected to the metal disk, which can ensure the reliability of the connection between the metal disk and the fixing member 310. The lower end of the fixing member 310 is provided with a threaded channel, and the upper end of the connecting member 320 is provided with an external thread. The upper end of the connecting member 320 is inserted into the threaded channel of the fixing member 310 and is threadedly connected to the threaded channel, which can achieve high-strength fixation between the fixing member 310 and the connecting member 320. It can not only ensure that the connecting member 320 is not easily loosened or separated when subjected to external forces during transportation and installation; but also can better transmit the vibration on the metal disk to the damping member 330 to improve the damping effect.

[0062] It can be understood that the upper end of the fixing member 310 can be fixed on the metal disk by welding or riveting; when the fixing member 310 is connected by welding, a welding cap can be provided at the upper end of the fixing member 310, so as to increase the welding area between the fixing member 310 and the metal disk, which is beneficial to ensuring the stability of welding; and after welding, the connection between the fixing member 310 and the metal disk is located on the upper end surface of the metal disk. When the body of the water heater is installed on the chassis assembly, the connection between the fixing member 310 and the metal disk can be covered, which can avoid the phenomenon that the connection between the fixing member 310 and the metal disk is corroded due to the exposure of the connection between the fixing member 310 and the metal disk to the outside.

[0063] It can be understood that the water receiving tray 200 is a plastic part. The plastic-made water receiving tray 200 has a low self-weight, which is beneficial to reducing the overall weight of the chassis assembly; and the plastic material has good toughness and corrosion resistance, so that the chassis assembly can be used for a long time in different external environments and can better meet the use requirements.

[0064] Referring to Figure 3 and Figure 4 In some embodiments, the upper end of the fixing member 310 is riveted to the metal disk, and the connection between the upper end of the fixing member 310 and the metal disk has high strength and can bear large external forces.

[0065] It can be understood that when the water heater operates, vibrations will be generated. When these vibrations pass through the metal disk and the fixing member 310, they will be converted into dynamic loads. Since the upper end of the fixing member 310 is riveted to the metal disk, the stress distribution at the riveted joint is relatively uniform, and stress concentration is not likely to occur, thereby reducing the impact of the dynamic load on the riveted joint between the fixing member 310 and the metal disk, which is beneficial to increasing the stability of the connection between the fixing member 310 and the metal disk.

[0066] Referring to Figure 3 and Figure 4 , in some embodiments, the fixing member 310 is cylindrical and has a connecting channel with an opening downward. The upper end of the connecting member 320 is threadedly connected to the connecting channel, which can not only ensure the stability of the connection between the fixing member 310 and the connecting member 320, but also simplify the installation process.

[0067] The water heater according to the second aspect embodiment of the present utility model includes a chassis assembly as provided in the first aspect embodiment of the present utility model.

[0068] According to the water heater of the embodiment of the present utility model, the water heater is installed on the chassis assembly. The vibration damping member 330 can effectively absorb the vibrations generated during the operation of the water heater, and can avoid the phenomenon of resonance between the machine body and the mounting bracket, resulting in screw loosening and wall abnormal noise, and reducing the noise during operation.

[0069] Referring to Figure 1 , it can be understood that the water heater further includes an electric heating tube 400. The support disk 100 of the chassis assembly is a metal disk, and the electric heating tube 400 is arranged on the metal disk; when the external temperature is relatively low, the electric heating tube 400 can heat the metal disk, and the heat of the metal disk is transferred to components such as the water receiving tray 200, thereby preventing ice formation.

[0070] Referring to Figure 1 , it can be understood that the support disk 100 is also provided with an installation groove for installing a water tank, a groove for installing the electric heating tube 400, etc. Specifically, in some embodiments, after the electric heating tube 400 is installed on the support disk 100, its upper end is flush with the upper end surface of the support disk 100, which can prevent the phenomenon that the installation of other components is affected due to the heating tube protruding above the support disk 100.

[0071] It can be understood that the chassis assembly further includes thermal insulation foam, and the thermal insulation foam is arranged between the support disk 100 and the water receiving tray 200. When the water heater operates, the internal temperature is relatively high, while the external temperature of the water heater is relatively low, which will cause a large temperature difference between the inside and outside of the water heater, and then lead to heat dissipation. By providing thermal insulation foam in the chassis assembly, the temperature difference between the external environment and the internal temperature can be effectively isolated, heat dissipation can be reduced, and the operating efficiency of the water heater can be improved.

[0072] Certainly, the present utility model is not limited to the above-mentioned embodiments. Those skilled in the art can make equivalent deformations or substitutions without departing from the spirit of the present utility model, and these equivalent deformations or substitutions are all included within the scope defined by the claims of this application.
