[0043] The first aspect of the present application discloses a support seat 3000, combined with Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 and Figure 8As shown, in some embodiments, the support seat 3000 is used to place the water heater tank 2000 thereon, thereby supporting the water heater tank 2000 , and the support seat 3000 is provided with a groove 3400 , and when the water heater tank 2000 is placed on the support seat 3000 , the water heater tank 2000 is inserted into the groove 3400 .

[0044] By setting a support base 3000, a groove 3400 is set on the support base 3000. When installing the water heater tank 2000, the water heater tank 2000 is inserted into the groove 3400. This can not only support the water heater tank 2000, but also position the water heater tank 2000, avoiding the assembly position of the water heater tank 2000 from being offset, so that the water heater tank 2000 can be accurately installed in place.

[0045] Specifically, the support base 3000 is described in detail below in conjunction with the water heater 100. The orientations involved below are based on the installation environment of the water heater 100. The water heater 100 close to the ground is the bottom, and the water heater 100 away from the ground is the top.

[0046] The water heater 100 includes a water heater inner tank 2000 and an outer shell 1000. The outer shell 1000 constitutes the outer structure of the water heater 100. The water heater inner tank 2000 needs to be installed in the outer shell 1000 so as to be covered by the outer shell 1000. The water heater inner tank 2000 is a vertical columnar structure as a whole. The outer shell 1000 needs to be adapted to the overall profile of the water heater inner tank 2000, that is, the outer shell 1000 also needs to be a vertical columnar structure. When the water heater inner tank 2000 is installed in the outer shell 1000, a receiving cavity 4200 needs to be formed between the water heater inner tank 2000 and the side 1200 of the outer shell 1000. The receiving cavity 4200 is used to set a heat preservation layer (not shown in the figure). For example, the heat preservation layer is formed by injecting a foaming material to play a role in heat preservation. In this embodiment, the support base 3000 is provided to realize the positioning and support of the water heater inner tank 2000, thereby preventing the assembly position of the water heater inner tank 2000 from being offset, thereby making the thickness of the accommodating cavity 4200 uniform.

[0047] The support base 3000 is used to place the water heater inner tank 2000 thereon, that is, the water heater inner tank 2000 is supported on the support base 3000 under the action of gravity. Specifically, the support base 3000 is arranged in the housing 1000, and the support base 3000 is placed on the bottom 1100 of the housing 1000. The support base 3000 is provided with a groove 3400. During the process of assembling the water heater inner tank 2000, the water heater inner tank 2000 is inserted into the groove 3400, so as to form the positioning and support of the water heater inner tank 2000. For example, the water heater tank 2000 includes a top plate 2100, a surrounding plate 2200 and a bottom plate 2300 (the water heater tank 2000 is described below using this structure as an example), the surrounding plate 2200 is a vertical cylindrical structure, the top plate 2100 is arranged at the top of the surrounding plate 2200 and arched upward, roughly forming an arc-shaped structure arched upward, the bottom plate 2300 is arranged at the bottom end of the surrounding plate 2200 and concave upward (that is, concave toward the inside of the water heater tank 2000), the bottom plate 2300 is roughly an arc-shaped structure, and the intersection 2400 of the bottom plate 2300 and the surrounding plate 2200 is inserted into the groove 3400 to be positioned and supported on the support seat 3000.

[0048] During the installation process, the water heater tank 2000 may not be inserted into the groove 3400 in one operation. In this case, it is necessary to lift the water heater tank 2000 again and then continue to put it down. After multiple attempts, it can be inserted into the groove 3400. Through the setting of the groove 3400, the water heater tank 2000 can be accurately installed in place, ensuring that the thickness of the accommodating cavity 4200 formed between the water heater tank 2000 and the side 1200 of the outer shell 1000 is uniform.

[0049] It is understandable that when the support base 3000 is placed on the bottom 1100 of the housing 1000, the position of the support base 3000 needs to be fixed relative to the housing 1000. For example, the support base 3000 can be fixed to the bottom 1100 of the housing 1000 during the manufacturing process of the housing 1000, or the support base 3000 and the side 1200 of the housing 1000 are abutted. Since the support base 3000 does not need to form a receiving cavity 4200 between the support base 3000 and the side 1200 of the housing 1000 for accommodating the thermal insulation layer, the radial size of the support base 3000 can be adapted to the radial size of the housing 1000. When the support base 3000 is set and placed on the bottom 1100 of the housing 1000, the support base 3000 can abut against the side 1200 of the housing 1000, thereby limiting the relative position of the support base 3000 relative to the housing 1000.

[0050] Combination Figure 8As shown, in some embodiments, the groove 3400 is annular, and the annular shape can be a circular ring, a square ring, or other shapes, as long as it can form an annular shape, so as to better achieve the positioning of the water heater liner 2000. By setting it in this way, the water heater liner 2000 can be positioned in the direction surrounding the water heater liner 2000 (i.e., surrounding the water heater liner 2000 in the horizontal direction), and the positioning effect of the water heater liner 2000 is further improved. In particular, since the bottom plate 2300 is arranged at the bottom end of the enclosure 2200 and is concave upward, the intersection 2400 of the bottom plate 2300 and the enclosure 2200 forms an annular structure, and by designing the groove 3400 to be annular, better matching is achieved, thereby improving the positioning effect. It can be understood that the groove 3400 is annular, and the groove 3400 can be a continuous and complete annular ring, or the groove 3400 can be composed of multiple parts, and the arrangement of the multiple parts is annular.

[0051] Combination Figure 8 and Fig.10 As shown, in some embodiments, the groove 3400 is gradually expanded from the bottom to the groove mouth, so that it is more convenient to insert the water heater tank 2000 into the groove 3400.

[0052] Specifically, the groove 3400 is open upward, and the water heater liner 2000 is placed on the support seat 3000 from top to bottom. During the process of the water heater 100 moving from top to bottom, the water heater liner 2000 is inserted from the notch of the groove 3400 until it abuts against the bottom of the groove 3400, and the water heater liner 2000 is assembled in place. As mentioned above, during the installation process of the water heater liner 2000, it may not be possible to insert the water heater liner 2000 into the groove 3400 in one operation, and it may take multiple attempts to insert it into the groove 3400. For this reason, in this embodiment, the direction from the bottom of the groove to the notch of the groove 3400 is designed to be gradually expanded, that is, the notch is larger and the bottom of the groove is smaller. The larger notch facilitates the water heater liner 2000 to pass through and insert into the groove 3400, and the smaller bottom of the groove effectively limits the displacement of the water heater liner 2000 in the horizontal direction, and the water heater liner 2000 has a smaller margin of activity after being placed on the support seat 3000.

[0053] Combination Fig.10 As shown, in some embodiments, the support seat 3000 includes an inner boss 3100, an outer boss 3300 and a support platform 3200. The inner boss 3100 and the outer boss 3300 are alternately arranged, and the support platform 3200 is arranged between the inner boss 3100 and the outer boss 3300. In this way, the inner boss 3100, the support platform 3200 and the outer boss 3300 surround the groove 3400 mentioned above. When the water heater tank 2000 is placed on the support seat 3000, the water heater tank 2000 covers the inner boss 3100.

[0054] Specifically, the inner boss 3100, the support platform 3200 and the outer boss 3300 surround the groove 3400, that is, the surface of the inner boss 3100 facing the outer boss 3300 constitutes one of the groove walls of the groove 3400, the surface of the outer boss 3300 facing the inner boss 3100 constitutes the other groove wall of the groove 3400, the surface of the support platform 3200 facing the space between the inner boss 3100 and the outer boss 3300 constitutes the groove bottom of the groove 3400, and a notch is formed between the inner boss 3100 and the outer boss 3300. When the water heater inner tank 2000 is placed on the support seat 3000, the water heater inner tank 2000 is inserted into the groove 3400 from the notch of the groove 3400 and abuts against the support platform 3200, so as to be supported by the support platform 3200, and the inner boss 3100 cooperates with the outer boss 3300 to limit the horizontal direction of the water heater inner tank 2000. At the same time, the water heater inner tank 2000 covers the inner boss 3100, specifically, the bottom plate 2300 of the water heater inner tank 2000 covers the inner boss 3100.

[0055] As mentioned above, the intersection 2400 of the bottom plate 2300 and the enclosure 2200 of the water heater inner tank 2000 is annular in structure, so designing the groove 3400 to be annular is more conducive to the cooperation between the intersection 2400 of the bottom plate 2300 and the enclosure 2200 and the groove 3400. For this purpose, based on the support seat 3000 including the inner boss 3100, the support platform 3200 and the outer boss 3300, the outer boss 3300 is designed to surround the inner boss 3100, for example Figure 8 As shown, the inner boss 3100 is located approximately in the middle of the support seat 3000, and the outer boss 3300 surrounds the inner boss 3100, so that the formed groove 3400 forms a ring shape.

[0056] It is understandable that the inner boss 3100, the support platform 3200 and the outer boss 3300 can be independent components connected together by connecting means, for example, the inner boss 3100, the support platform 3200 and the outer boss 3300 are fixed together by bonding, screwing, clamping, welding, welding, etc. The main function of the support seat 3000 is to realize positioning and support of the water heater liner 2000, so the structure of the support seat 3000 can be relatively simple, and the support seat 3000 can be prepared by an integrated molding process, that is, the support seat 3000 is integrally molded with the inner boss 3100, the support platform 3200 and the outer boss 3300, which has higher production efficiency and makes the support seat 3000 have higher structural strength (relative to the solution in which independent components are connected together by connecting means), and more effective support is achieved for the water heater liner 2000 with a certain weight, and the support seat 3000 is not easy to break when the weight of the water heater liner 2000 is applied to the support seat 3000. For example, the support seat 3000 is integrally formed by injection molding to form an inner boss 3100, a support platform 3200 and an outer boss 3300.

[0057] Combination Figure 8 As shown, in some embodiments, the inner boss 3100 includes a first protrusion 3110, and the first protrusion 3110 is used to abut against the portion of the water heater inner tank 2000 covering the inner boss 3100. It can be understood that when the water heater inner tank 2000 is placed on the support seat 3000, the corresponding portion of the water heater inner tank 2000 covers the inner boss 3100. In this embodiment, the inner boss 3100 includes the first protrusion 3110, and the portion of the water heater inner tank 2000 covering the inner boss 3100 is supported by the first protrusion 3110, which is conducive to preventing the water heater inner tank 2000 from rupturing under water pressure.

[0058] Taking the water heater tank 2000 including the top plate 2100, the enclosure 2200 and the bottom plate 2300 as an example, the enclosure 2200 is a vertical cylindrical structure, the top plate 2100 is arranged at the top of the enclosure 2200 and arches upward, and is generally an arc-shaped structure arched upward, the bottom plate 2300 is arranged at the bottom end of the enclosure 2200 and is concave upward (i.e., concave toward the inside of the water heater tank 2000), the bottom plate 2300 is generally an arc-shaped structure, and the intersection 2400 of the bottom plate 2300 and the enclosure 2200 is inserted into the groove 3400 to be positioned and supported on the support seat 3000. By designing the bottom plate 2300 to be concave upward, in addition to making the intersection 2400 of the bottom plate 2300 and the enclosure 2200 form an annular structure to enhance the placement stability of the water heater tank 2000, the pressure bearing capacity of the bottom plate 2300 is also enhanced. It is understandable that the water heater liner 2000 is in a vertical cylindrical shape. When the water heater liner 2000 stores a certain amount of water, the gravity of the water is applied to the bottom plate 2300. By designing the bottom plate 2300 to be concave upward, such a design can strengthen the structural strength of the bottom plate 2300 itself, which is more conducive to pressure bearing. Of course, designing the bottom plate 2300 to be concave upward also has some other technical effects, which will not be repeated here one by one. When the water heater liner 2000 is placed on the support seat 3000, the bottom plate 2300 of the water heater liner 2000 covers the inner boss 3100 (the bottom plate 2300 constitutes the part of the water heater liner 2000 covering the inner boss 3100), at this time, the first protrusion 3110 of the inner boss 3100 contacts the bottom plate 2300 and supports the bottom plate 2300, and the bottom plate 2300 is less likely to break.

[0059] Further, continue to combine Figure 8As shown, in some embodiments, the inner boss 3100 includes a plurality of first protrusions 3110, and the term "a plurality" means two or more, that is, the number of the first protrusions 3110 is at least two, and the plurality of first protrusions 3110 are designed to be arranged alternately along the circumference of the inner boss 3100, and the circumference can be understood as the direction surrounding the center of the inner boss 3100 in the horizontal direction. Since the portion of the water heater inner tank 2000 covering the inner boss 3100 has a certain coverage range, in this embodiment, by providing a plurality of first protrusions 3110, the plurality of first protrusions 3110 are designed to be arranged alternately, so as to facilitate the realization of a large-scale support for the portion of the water heater inner tank 2000 covering the inner boss 3100 through the plurality of first protrusions 3110, for example, the water heater inner tank 2000 realizes the coverage of the inner boss 3100 through the bottom plate 2300, and the plurality of first protrusions 3110 can realize a large-scale support for the bottom plate 2300. It can be understood that the first raised portion 3110 includes a plurality of first raised portions 3110, and the plurality of first raised portions 3110 are arranged alternately. In addition to being able to provide a large-scale support for the base plate 2300, it is also helpful to reduce the amount of material used, reduce costs, and avoid the support base 3000 being too heavy.

[0060] Combination Figure 3 , Figure 7 and Figure 8 As shown, in some embodiments, the first protrusion 3110 is designed to be arranged in a similar shape to the portion of the water heater inner tank 2000 covering the inner boss 3100. The so-called similar shape means that the surface shape of the first protrusion 3110 and the portion of the water heater inner tank 2000 covering the inner boss 3100 that contact each other is similar. For example, the bottom plate 2300 is concavely arranged upward and is generally in an arc-shaped structure, so the surface where the first protrusion 3110 contacts the bottom plate 2300 also has an adapted arc-shaped structure, so that the first protrusion 3110 contacts the bottom plate 2300 when supporting the bottom plate 2300, reducing the concentration of pressure in a small range and avoiding deformation of the bottom plate 2300.

[0061] Combination Figure 8 As shown, in some embodiments, the outer boss 3300 includes a plurality of second protrusions 3310 , that is, the number of the second protrusions 3310 is at least two, the plurality of second protrusions 3310 are alternately arranged along a direction surrounding the inner boss 3100 , and the second protrusions 3310 are higher than the groove 3400 .

[0062] It is understandable that when the water heater tank 2000 is placed on the support base 3000, since the water heater tank 2000 has a certain height, the water heater tank 2000 is prone to swing relative to the support base 3000. By designing the second raised portion 3310, the second raised portion 3310 is raised to increase the contact range with the water heater tank 2000 (the contact range in the up and down directions), thereby strengthening the constraint on the water heater tank 2000, thereby effectively preventing the water heater tank 2000 from swinging.

[0063] In addition, in this embodiment, the number of the second protrusions 3310 is at least two, and the adjacent second protrusions 3310 are arranged alternately, which can effectively reduce the amount of material used, thereby reducing costs and avoiding the support base 3000 from being too heavy.

[0064] Further, continue to combine Figure 8 As shown, in some embodiments, the side of the second protrusion 3310 facing the inner boss 3100 is designed to be inclined from bottom to top away from the inner boss 3100. Specifically, since the second protrusion 3310 is in a protruding shape and is higher than the groove 3400, during the process of inserting the water heater inner tank 2000 into the groove 3400, the water heater inner tank 2000 first passes through the second protrusion 3310 and may touch the second protrusion 3310. By designing the side of the second protrusion 3310 facing the inner boss 3100 to be inclined from bottom to top away from the inner boss 3100, it plays a guiding role in the installation of the water heater inner tank 2000, making it easier for the water heater inner tank 2000 to be aligned with the groove 3400 and inserted.

[0065] In some embodiments, in combination Figure 3 and Figure 5 As shown, when the water heater tank 2000 is placed on the support base 3000 , a receiving cavity 4100 is surrounded between the support base 3000 and the water heater tank 2000 , and the support base 3000 is provided with a connecting groove 3500 , which connects the receiving cavity 4100 with the external space 4200 of the water heater tank 2000 .

[0066] When the water heater tank 2000 is placed on the support base 3000, a receiving chamber 4100 is formed between the water heater tank 2000 and the support base 3000. A connecting groove 3500 is provided on the support base 3000 to connect the receiving chamber 4100 and the external space 4200 of the water heater tank 2000. In the process of manufacturing the water heater 100, the material constituting the thermal insulation layer (such as foaming material) can enter the receiving chamber 4100 from the external space 4200 of the water heater tank 2000 through the connecting groove 3500, and can also enter the external space 4200 of the water heater tank 2000 from the receiving chamber 4100 through the connecting groove 3500, thereby filling the external space 4200 of the water heater tank 2000, the connecting groove 3500 and the receiving chamber 4100, thereby improving the thermal insulation performance of the water heater tank 2000.

[0067] For example, taking a water heater as an example for detailed description, the water heater tank 2000 includes a top plate 2100, a surrounding plate 2200 and a bottom plate 2300. For example, the surrounding plate 2200 is a vertical cylindrical structure, the top plate 2100 is arranged at the top of the surrounding plate 2200 and arches upward, roughly forming an arc-shaped structure arched upward, the bottom plate 2300 is arranged at the bottom end of the surrounding plate 2200 and is recessed upward (that is, recessed toward the inside of the water heater tank 2000), the bottom plate 2300 is roughly an arc-shaped structure, and the intersection 2400 of the bottom plate 2300 and the surrounding plate 2200 is inserted into the groove 3400 so as to be positioned and supported on the support seat 3000, the bottom plate 2300 is recessed upward so as to form a accommodating cavity 4100 between the support seat 3000, and at the same time, a accommodating cavity 420 is formed between the water heater tank 2000 and the side 1200 of the shell 1000 0 (the accommodating chamber 4200 is the external space 4200 of the water heater inner tank 2000), the support seat 3000 is provided with a connecting groove 3500, and the connecting groove 3500 connects the accommodating chamber 4100 and the accommodating chamber 4200. When the material constituting the thermal insulation layer is injected into the accommodating chamber 4200, these materials enter the accommodating chamber 4100 from the accommodating chamber 4200 through the connecting groove 3500, or when the material constituting the thermal insulation layer is injected into the accommodating chamber 4100, these materials enter the accommodating chamber 4200 from the accommodating chamber 4100 through the connecting groove 3500, so that the thermal insulation layer is filled in the accommodating chamber 4200, the connecting groove 3500 and the accommodating chamber 4100, which not only forms a heat insulation effect between the side portion 1200 of the outer shell 1000 and the water heater inner tank 2000, but also forms a heat insulation effect between the support seat 3000 and the water heater inner tank 2000.

[0068] Combination Figure 8 As shown, in some embodiments, the communicating grooves 3500 include a plurality, that is, the number of the communicating grooves 3500 is at least two, and the plurality of communicating grooves 3500 are designed to be alternately arranged along the circumference of the support seat 3000 .

[0069] Specifically, the accommodating cavity 4200 formed between the water heater inner tank 2000 and the side portion 1200 of the outer shell 1000 surrounds the water heater inner tank 2000, and the whole is an annular space. Taking the injection of the material constituting the thermal insulation layer from the accommodating cavity 4200 as an example, by providing a plurality of connecting grooves 3500 arranged alternately along the circumference of the support seat 3000, the material constituting the thermal insulation layer can enter the accommodating cavity 4100 from multiple directions through the connecting grooves 3500, thereby reducing the resistance to the flow of these materials and facilitating the reduction of the existence of vacancies in the accommodating cavity 4100, thereby further improving the thermal insulation performance.

[0070] Furthermore, the volume of the connecting groove 3500 is not greater than 40% of the volume of the support seat 3000. For example, the volume of the connecting groove 3500 is 5%, 10%, 15%, 20%, 25%, 30% or 35% of the volume of the support seat 3000. It can be understood that the water heater tank 2000 is placed on the support seat 3000 and is supported by the support seat 3000. The weight of the water heater tank 2000 is applied to the support seat 3000. Therefore, the support seat 3000 needs to ensure a certain structural strength. Since the setting of the connecting groove 3500 is equivalent to forming a hollow structure on the support seat 3000, the volume occupied by the connecting groove 3500 should not be too large. In this embodiment, by limiting the volume share of the connecting groove 3500, the performance requirements of the material constituting the support seat 3000 can be reduced while ensuring the structural strength of the support seat 3000. It is understandable that the volume of the connecting groove 3500 may be greater than 40%, but in this case, the requirements for the material constituting the support seat 3000 are higher.

[0071] Combination Figure 5 and Figure 8 As shown, in some embodiments, the end of the connecting groove 3500 connected to the accommodating cavity 4200 is designed to be open upward.

[0072] Specifically, the water heater tank 2000 is placed on the support seat 3000. At this time, the water heater tank 2000 is supported on the support seat 3000 under the action of gravity and is located above the support seat 3000. The accommodating cavity 4200 is also located above the support seat 3000. The end of the connecting groove 3500 connecting the accommodating cavity 4200 is designed to be open upward. When the material constituting the thermal insulation layer is injected into the accommodating cavity 4200, these materials enter the connecting groove 3500 from top to bottom, which makes it easier for these materials to flow to the accommodating cavity 4100, thereby further reducing the flow resistance of these materials.

[0073] Combination Figure 8 and Fig. 9As shown, in some embodiments, the connecting groove 3500 is exposed at the bottom surface of the support seat 3000. Specifically, the support seat 3000 is placed on the bottom 1100 of the housing 1000, and the support seat 3000 and the bottom 1100 of the housing 1000 are not sealed. When the materials constituting the thermal insulation layer are injected into the accommodating cavity 4200, as these materials are continuously injected, the air in the accommodating cavity 4200 is discharged from the housing 1000 (the housing 1000 is also not completely sealed, and there are small gaps), and the connecting groove 3500 is exposed at the bottom surface of the support seat 3000, thereby increasing the air flow path (the air can enter the connecting groove 3500 from the accommodating cavity 4200 and then flow from the connecting groove 3500 to between the support seat 3000 and the bottom 1100 of the housing 1000, and then be discharged from the housing 1000), which makes it easier for the air to be discharged from the housing 1000.

[0074] Furthermore, combined with Figure 8 and Fig. 9 As shown, in some embodiments, the support base 3000 is provided with a connecting hole 3600, the connecting hole 3600 is connected to the accommodating cavity 4100, and the connecting hole 3600 is exposed at the bottom surface of the support base 3000. As mentioned above, the support base 3000 is placed on the bottom 1100 of the housing 1000, and the support base 3000 and the bottom 1100 of the housing 1000 are not sealed. When the material constituting the thermal insulation layer is injected into the accommodating cavity 4200 and enters the accommodating cavity 4100 through the connecting groove 3500, the air in the accommodating cavity 4100 can flow out from the bottom surface of the support base 3000 through the connecting hole 3600, thereby increasing the air flow path, and then facilitating the air to be discharged from the accommodating cavity 4100, and minimizing the accumulation of air in the accommodating cavity 4100.

[0075] The second aspect of the present application discloses a water heater 100, Figures 1 to 10 As shown, the water heater 100 includes a water heater inner tank 2000 and the above-mentioned support base 3000. The support base 3000 is used for placing the water heater inner tank 2000 thereon, so as to support the water heater inner tank 2000. The support base 3000 is provided with a groove 3400. When the water heater inner tank 2000 is placed on the support base 3000, the water heater inner tank 2000 is inserted into the groove 3400. By providing the support base 3000, the support base 3000 is provided with a groove 3400. When the water heater inner tank 2000 is installed, the water heater inner tank 2000 is inserted into the groove 3400. In this way, the water heater inner tank 2000 can be supported and positioned, so as to avoid the assembly position of the water heater inner tank 2000 from being offset, so that the water heater inner tank 2000 can be accurately installed in place.

[0076] The water heater 100 includes a water heater inner tank 2000 and an outer shell 1000. The outer shell 1000 constitutes the outer structure of the water heater 100. The water heater inner tank 2000 needs to be installed in the outer shell 1000 so as to be covered by the outer shell 1000. The water heater inner tank 2000 is a vertical columnar structure as a whole. The outer shell 1000 needs to be adapted to the overall profile of the water heater inner tank 2000, that is, the outer shell 1000 also needs to be a vertical columnar structure. When the water heater inner tank 2000 is installed in the outer shell 1000, a receiving cavity 4200 needs to be formed between the water heater inner tank 2000 and the side 1200 of the outer shell 1000. The receiving cavity 4200 is used to set a heat preservation layer (not shown in the figure). For example, the heat preservation layer is formed by injecting a foaming material to play a role in heat preservation. In this embodiment, the support base 3000 is provided to realize the positioning and support of the water heater inner tank 2000, thereby preventing the assembly position of the water heater inner tank 2000 from being offset, thereby making the thickness of the accommodating cavity 4200 uniform.

[0077] The support base 3000 is used to place the water heater inner tank 2000 thereon, that is, the water heater inner tank 2000 is supported on the support base 3000 under the action of gravity. Specifically, the support base 3000 is arranged in the housing 1000, and the support base 3000 is placed on the bottom 1100 of the housing 1000. The support base 3000 is provided with a groove 3400. During the process of assembling the water heater inner tank 2000, the water heater inner tank 2000 is inserted into the groove 3400, so as to form the positioning and support of the water heater inner tank 2000. For example, the water heater tank 2000 includes a top plate 2100, a surrounding plate 2200 and a bottom plate 2300. The surrounding plate 2200 is a vertical cylindrical structure. The top plate 2100 is arranged at the top of the surrounding plate 2200 and arched upward, roughly forming an arc-shaped structure arched upward. The bottom plate 2300 is arranged at the bottom end of the surrounding plate 2200 and recessed upward (that is, recessed toward the interior of the water heater tank 2000). The bottom plate 2300 is roughly an arc-shaped structure. The intersection 2400 of the bottom plate 2300 and the surrounding plate 2200 is inserted into the groove 3400 to be positioned and supported on the support seat 3000.

[0078] During the installation process, the water heater tank 2000 may not be inserted into the groove 3400 in one operation. In this case, it is necessary to lift the water heater tank 2000 again and then continue to put it down. After multiple attempts, it can be inserted into the groove 3400. Through the setting of the groove 3400, the water heater tank 2000 can be accurately installed in place, ensuring that the thickness of the accommodating cavity 4200 formed between the water heater tank 2000 and the side 1200 of the outer shell 1000 is uniform.

[0079] When the support base 3000 is placed on the bottom 1100 of the housing 1000, the position of the support base 3000 needs to be fixed relative to the housing 1000. For example, the support base 3000 can be fixed to the bottom 1100 of the housing 1000 during the manufacturing process of the housing 1000, or the support base 3000 and the side 1200 of the housing 1000 are abutted. Since the support base 3000 does not need to form a receiving cavity 4200 between the support base 3000 and the side 1200 of the housing 1000 for accommodating the thermal insulation layer, the radial size of the support base 3000 can be adapted to the radial size of the housing 1000. When the support base 3000 is set and placed on the bottom 1100 of the housing 1000, the support base 3000 can abut against the side 1200 of the housing 1000, thereby limiting the relative position of the support base 3000 relative to the housing 1000.

[0080] It is understandable that the water heater 100 adopts the support base 3000 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.

[0081] The above description is only a preferred embodiment of the present application, and does not limit the patent scope of the present application. All equivalent structural changes made based on the concept of the present application and the contents of the present application description and drawings, or direct / indirect application in other related technical fields are included in the patent protection scope of the present application.
