Mounting structure, water tank and water heater

Abstract

The application discloses a mounting structure, a water tank and a water heater. The mounting structure comprises a hanging lug, a first connecting part and a second connecting part. The hanging lug is used for suspending and mounting an inner container. The first connecting part is connected to the hanging lug and used for connecting with a top of the inner container. The second connecting part is connected to the hanging lug and used for connecting with a back of the inner container. The hanging lug, the first connecting part and the second connecting part are adjacent to the connection between the top of the inner container and the back of the inner container. Thus, the mounting structure is arranged at the connection between the top of the inner container and the back of the inner container (i.e. an edge region), which is a reinforced region formed by the intersection of two metal planes and has higher bending stiffness and local carrying capacity. Compared with the mode of welding a support in the middle of a flat plate, the mounting structure can effectively disperse the suspension load, avoid the deformation of the inner container or the cracking of a weld caused by stress concentration, and significantly improve the overall structural stability.

Description

Technical Field

[0001] This application relates to the field of household appliance technology, and in particular to an installation structure, a water tank, and a water heater. Background Technology

[0002] With the popularization of energy conservation and environmental protection concepts and the improvement of users' requirements for quality of life, household water heaters are developing towards high efficiency, energy saving, compact structure, and convenient installation. Among them, the heat exchange tank, as the core component of the water heater, directly affects the overall performance and user experience due to its insulation performance, structural strength, and installation reliability.

[0003] However, in existing water heater products, the common suspension structure involves welding a metal bracket to the large flat surface on the back of the inner tank. The bracket has threaded holes or connectors, and bolts are used to connect the external mounting bracket to the bracket, thus achieving wall mounting of the water tank. When the suspension bracket is welded to the middle area of ​​the large flat surface on the back of the inner tank, this area is a thin plate structure with low bending stiffness. When the water tank is fully loaded, the weight is concentrated on the center of the plate, which can easily cause localized dents or overall warping, affecting the structural integrity of the inner tank and potentially leading to weld cracking or leakage in severe cases. Utility Model Content

[0004] This application provides an installation structure, a water tank, and a water heater, which can solve at least one of the above-mentioned technical problems.

[0005] In a first aspect, embodiments of this application provide an installation structure applied to a water heater, the water heater including an inner tank, the inner tank having a connected top and a back of the inner tank, the installation structure including:

[0006] Hanging ears are used for suspending and installing the inner liner;

[0007] A first connecting part, the first connecting part being connected to the hook and used for connection with the top of the inner liner; and

[0008] The second connecting part is connected to the hook and is used to connect to the back of the inner liner;

[0009] The ear loop, the first connecting part, and the second connecting part are all located near the connection between the top of the inner liner and the back of the inner liner.

[0010] In some embodiments, the first connecting portion and the second connecting portion are located at the same end of the lug, and the extending direction of the first connecting portion is perpendicular to the extending direction of the second connecting portion.

[0011] In some embodiments, there are multiple second connecting portions, and the first connecting portion is provided on both sides.

[0012] In some implementations, the ear has a hanging hole that extends through both opposite sides of the ear.

[0013] In some embodiments, the lugs are provided with reinforcing ribs that surround the edge of the hanging hole.

[0014] In some embodiments, the lugs are provided with reinforcing folds that surround the edge of the lugs.

[0015] In some embodiments, the lug has a reinforcing side and a mounting side arranged opposite to each other, with reinforcing ribs and reinforcing flanges located on the reinforcing side.

[0016] In some embodiments, the ear loop has an insulating layer that covers the outer surface of the ear loop.

[0017] Secondly, embodiments of this application provide a water tank, comprising:

[0018] The inner liner has a connected top and a connected back; and

[0019] In any of the above embodiments, the mounting structure is connected to the top of the inner liner and the back of the inner liner, and is disposed near the connection point between the top of the inner liner and the back of the inner liner.

[0020] Thirdly, embodiments of this application provide a water heater, including:

[0021] The water tank in any of the above embodiments; and

[0022] Heating element, used to heat the water in the water tank.

[0023] The installation structure, water tank, and water heater provided in this application include a hanging ear, a first connecting part, and a second connecting part. The hanging ear is used for suspending the inner tank. The first connecting part is connected to the hanging ear and is used to connect to the top of the inner tank. The second connecting part is connected to the hanging ear and is used to connect to the back of the inner tank. The hanging ear, the first connecting part, and the second connecting part are all located near the connection between the top and back of the inner tank. Thus, this application positions the installation structure at the connection between the top and back of the inner tank (i.e., the edge area), a reinforced area formed by the intersection of two metal planes, which has higher bending stiffness and local load-bearing capacity. Compared to welding a bracket in the middle of a flat plate, this effectively disperses the suspension load, avoids inner tank deformation or weld cracking due to stress concentration, and significantly improves the overall structural stability. Furthermore, the installation structure is integrated into the junction area between the top and back of the inner tank, does not protrude from the center of the large flat surface, and will not cause physical interference with the adhesion of the vacuum insulation panel. Therefore, vacuum insulation panels can be continuously and completely laid on the back of the inner liner and other surfaces to reduce the number of seams, reduce the thermal bridging effect, thereby improving the overall insulation efficiency and helping to save energy and reduce consumption.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0036] Please see Figures 1 to 4 This application provides an installation structure 10 for use in a water heater. The water heater includes an inner tank 400, which has a connected top 410 and a back 420. The installation structure 10 includes a hanging ear 100, a first connecting portion 200, and a second connecting portion 300. The hanging ear 100 is used for suspending the inner tank 400. The first connecting portion 200 is connected to the hanging ear 100 and is used to connect to the top 410 of the inner tank. The second connecting portion 300 is connected to the hanging ear 100 and is used to connect to the back 420 of the inner tank. The hanging ear 100, the first connecting portion 200, and the second connecting portion 300 are all located adjacent to the connection point between the top 410 and the back 420 of the inner tank.

[0037] Thus, this application positions the mounting structure 10 at the connection point (i.e., the edge area) between the top 410 and the back 420 of the inner liner. This location is a reinforced area formed by the intersection of two metal planes, providing higher bending stiffness and local load-bearing capacity. Compared to welding the bracket in the middle of the flat plate, this effectively disperses the suspended load, preventing deformation of the inner liner 400 or weld cracking due to stress concentration, and significantly improving the overall structural stability.

[0038] Furthermore, the installation structure 10 is integrated into the junction area between the top 410 and the back of the inner liner, without protruding from the center of the large flat surface, thus avoiding physical interference with the adhesion of the vacuum insulation panel. Therefore, the vacuum insulation panel can be continuously and completely laid on the back 420 of the inner liner and other surfaces, reducing the number of seams, reducing the thermal bridging effect, thereby improving the overall insulation efficiency and contributing to energy saving and consumption reduction.

[0039] The inner liner 400 is made of sheet metal and is in the shape of a cuboid. Its top plane and the vertical plane of its back are connected to each other, forming a boundary edge that extends laterally. This boundary area has high structural rigidity and resistance to deformation due to the orthogonal connection of the two metal plates, making it suitable as a major load-bearing connection point.

[0040] The hanging lug 100 is the main load-bearing component, used to cooperate with the external bracket on the wall to complete the hoisting action. The hanging lug 100 is equipped with a first connecting part 200 and a second connecting part 300. The first connecting part 200 extends laterally from the hanging lug 100 and towards the top 410 of the inner liner, for establishing a fixed connection with the plane of the top 410 of the inner liner; the second connecting part 300 extends downward from the hanging lug 100 and towards the back 420 of the inner liner, for establishing a fixed connection with the plane of the back 420 of the inner liner. The first connecting part 200 and the second connecting part 300 are connected to the top 410 and the back 420 of the inner liner respectively by welding (or screw connection), forming a stable connection structure with double-sided support.

[0041] The overall layout of the hanging lug 100, the first connecting part 200, and the second connecting part 300 is concentrated near the connection between the top 410 and the back 420 of the inner liner, making full use of the structural strength advantage of this area. When the water tank 20 is fully loaded, the suspended load is transferred to the two connecting parts through the hanging lug 100, and then respectively introduced into the top and back metal plates, realizing multi-path load sharing, effectively avoiding concentrated stress on a single plane, and preventing dents or warping in the thin plate area.

[0042] Because the mounting ears 100 and their connecting parts are located at the junction of the top and back panels, rather than at the center of the large flat surface of the back panel, the main back panel remains flat and free of protrusions, allowing the vacuum insulation panel to be continuously adhered to the entire back panel surface. As a high-efficiency insulation material, the integrity of the vacuum insulation panel directly affects its insulation performance. This structure avoids the cutting and splicing problems caused by avoiding brackets, reduces the number of thermal bridges, improves the overall insulation effect, and helps to improve the energy efficiency rating of the water heater.

[0043] In some embodiments, the first connecting portion 200 and the second connecting portion 300 are located at the same end of the lug 100, and the extending direction of the first connecting portion 200 is perpendicular to the extending direction of the second connecting portion 300.

[0044] One end of the lug 100 integrates a first connecting portion 200 and a second connecting portion 300. Both connecting portions are located in the same end region of the lug 100, forming a compact connecting unit. This layout allows welding operations to be concentrated in a local area, facilitating precise positioning and continuous welding on automated production lines, thereby improving assembly efficiency and process consistency.

[0045] The first connecting part 200 extends horizontally, its extension path being parallel to the plane of the inner liner top 410, for establishing a surface contact connection with the inner liner top 410. The second connecting part 300 extends vertically, its extension path being parallel to the plane of the inner liner back 420, for establishing a surface contact connection with the inner liner back 420. The extension directions of the first connecting part 200 and the second connecting part 300 are orthogonal at 90°, forming a right-angle connection structure that perfectly matches the geometric angle between the inner liner top 410 and the back.

[0046] This right-angle connection structure makes full use of the space at the junction of the top 410 and the back of the inner liner, allowing the first connecting part 200 and the second connecting part 300 to be attached and welded to two mutually perpendicular metal surfaces, forming a stable L-shaped support. This double-sided welding method significantly enhances the connection strength, effectively resisting the shear force, bending moment and torsional force generated during suspension, and preventing the hanging ear 100 from loosening or falling off under long-term load.

[0047] Since the first connecting part 200 and the second connecting part 300 act on the metal plate surfaces in two different directions, the load is decomposed into two component forces after passing through the lug 100, which are then transmitted to the top plate and the back plate respectively. This multi-directional force transmission mechanism avoids a single plane bearing the entire suspension weight, reduces the risk of local stress concentration, and further improves the overall rigidity and durability of the inner liner 400 structure.

[0048] The main body of the lug 100 is manufactured using stamping or bending processes, and is processed from a single metal sheet. This ensures that there are no seams between the first connecting part 200, the second connecting part 300, and the main body of the lug 100, resulting in a continuous and complete structure with good mechanical properties and manufacturing consistency. The metal material is preferably the same stainless steel or low-carbon steel as the inner liner 400 to ensure welding compatibility and long-term corrosion resistance.

[0049] After welding is completed, the exposed portion of the mounting lug 100 undergoes overall insulation treatment, forming a uniform insulation layer on its surface through plastic coating or injection molding. The insulation layer covers the perimeter of the mounting hole 101, the transition area of ​​the connection, and all exposed metal areas, ensuring that users do not directly contact conductive parts during installation or maintenance, thus meeting the electrical safety requirements of household appliances in humid environments.

[0050] In some embodiments, there are multiple second connecting portions 300, and the first connecting portion 200 is provided with second connecting portions 300 on both sides.

[0051] Multiple second connecting parts 300 are provided, all concentrated in the same end region of the loop 100, forming a composite connecting structure together with the first connecting part 200. The multiple second connecting parts 300 are symmetrically distributed laterally, located on the left and right sides of the first connecting part 200, forming a "one-center-two-sides" layout. This structure enhances the connection area and mechanical stability between the loop 100 and the inner liner back 420.

[0052] Each second connecting part 300 extends vertically, its extension path parallel to the plane of the inner liner back 420, and its end edge is attached to the metal surface of the inner liner back 420, achieving a fixed connection through welding. The two second connecting parts 300 are respectively arranged in the outer area of ​​the first connecting part 200, and the three together form a laterally symmetrical support frame around the hanging ear 100 body, improving the overall structure's torsional resistance and load balance.

[0053] The first connecting part 200 is centrally located and directly connects to the top plane 410 of the inner liner, bearing the main vertical tensile load. The second connecting parts 300 on both sides mainly transmit shear force and bending moment, and resist torsional stress caused by installation deviation or external vibration. The multi-point connection method makes the suspension moment distribution more uniform, effectively reduces the stress concentration of local welds, and extends the fatigue life of the connection parts.

[0054] This multi-connection structure is manufactured using a one-piece molding process, formed from a single metal sheet through stamping and bending. This ensures that there are no splicing joints between the first connecting part 200 and the two second connecting parts 300, resulting in a continuous and complete structure. The material selected is stainless steel or low-carbon steel that matches the inner liner 400, ensuring weld metallurgical compatibility and long-term structural reliability.

[0055] The symmetrically arranged second connecting parts 300 on both sides improve positioning accuracy and assembly tolerance during the welding process. On automated production lines, this structure can be quickly positioned using fixtures, enabling simultaneous welding of the top and back, reducing process time and improving production efficiency. Simultaneously, the symmetrical design helps counteract the tendency for twisting caused by thermal deformation during welding, maintaining the overall form and position tolerances of the inner liner 400.

[0056] In some embodiments, the ear loop 100 is provided with a hanging hole 101, which extends through the opposite sides of the ear loop 100.

[0057] The lug 100 is provided with a hanging hole 101 for suspension connection. The hanging hole 101 is a through structure that runs through the opposite two sides of the lug 100 body. This through structure makes the hanging hole 101 a complete through hole, which can accommodate external hooks, pins or bolts to be inserted from any direction and complete locking or fastening operations, meeting the assembly needs of different installation scenarios.

[0058] The axis of the hanging hole 101 is perpendicular to the extension plane of the main body of the hanging lug 100. The hole is cylindrical or elliptical, with a smooth, burr-free inner wall to prevent the connector from scratching or getting stuck during insertion. The hole diameter is designed according to the load-bearing requirements and standard hook specifications to ensure that the connector has an appropriate clearance after insertion, maintaining sufficient contact area to transfer load while ensuring smooth assembly.

[0059] The through-hole design 101 enhances the flexibility and error tolerance of the installation process. Installers can align the pre-installed wall hooks with the hanging holes 101 from either the front or rear of the water tank 20 and complete the installation without strictly limiting the direction of operation. This feature is particularly advantageous in confined installation spaces or when visibility is obstructed, significantly improving on-site work efficiency and user experience.

[0060] The mounting hole 101 is located in the upper part of the mounting lug 100, near the top of the water tank 20, and is within the visible height range after the entire unit is assembled. During installation, the operator can directly observe the relative position of the mounting hole 101 and the wall hook, enabling quick alignment and precise attachment, reducing repeated adjustment time and improving installation convenience.

[0061] In some embodiments, the lug 100 is provided with a reinforcing rib 110, which surrounds the edge of the hanging hole 101.

[0062] The lug 100 is provided with a reinforcing rib 110, which is a structural feature protruding from the surface of the lug 100 body and is completely surrounded around the outer periphery of the hanging hole 101. This rib structure forms a closed or nearly closed annular contour around the hanging hole 101, is integrally formed with the lug 100 base, constitutes a local reinforcement area, and significantly improves the structural rigidity and deformation resistance around the hanging hole 101.

[0063] The reinforcing rib 110 is integrally formed on the metal plate of the lug 100 by stamping or molding. Its cross-section is arc-shaped, trapezoidal, or rectangular, with a height of 0.5mm to 3mm and a width of 2mm to 8mm. The specific dimensions are optimized according to the material thickness and load-bearing requirements of the lug 100. The rib extends continuously along the circumference of the hanging hole 101 to ensure that the load is evenly distributed around the hole and to avoid stress concentration or tearing at the hole edge due to local weakness.

[0064] As a key stress point for the suspension connection, the hanging hole 101 bears significant tensile and shear forces under full load conditions in the water tank 20. The presence of the reinforcing rib 110 effectively disperses the concentrated stress acting on the edge of the hanging hole 101, improving the fatigue strength of the hanging lug 100 under long-term dynamic loads. This structure is particularly suitable for high-frequency vibration or alternating thermal expansion and contraction conditions, preventing structural failure due to the propagation of metal microcracks.

[0065] Reinforcing ribs 110 are arranged around the edge of the hanging hole 101 to form a ring-shaped support frame, which enhances the overall planar stability of the hanging ear 100 body. When external force is applied to the hanging hole 101 through the hook or pin, the load is quickly transmitted to the surrounding hanging ear 100 body through the ribs, reducing local bending deformation, maintaining the integrity of the hole shape, and ensuring the stable engagement of the connector.

[0066] In some embodiments, the ear loop 100 is provided with a reinforcing fold 120, which surrounds the edge of the ear loop 100.

[0067] The lug 100 is provided with a reinforcing folded edge 120, which is a structural feature set along the outer periphery of the lug 100 body, extending around the overall outline of the lug 100 and forming a closed or continuous annular edge. This folded edge is processed by the flanging process of metal sheet, which transforms the surrounding area of ​​the lug 100 from a planar state to a side-standing structure with a certain height, significantly improving the bending stiffness and overall structural stability of the lug 100.

[0068] A reinforcing folded edge 120 surrounds the entire outer perimeter of the hook 100, including the boundaries near the first connecting part 200, the second connecting part 300, and the area where the hook hole 101 is located, forming a continuous closed frame shape. The height of the folded edge is 3mm to 10mm, with the specific value determined based on the size of the hook 100, the material thickness, and the load-bearing requirements. The folded edge cross-section has a right angle or rounded transition shape, smoothly connecting with the hook 100 base to avoid stress concentration and enhance the impact resistance of the edge area.

[0069] During suspension, the lug 100, as the main load-bearing component, is prone to out-of-plane deflection or torsional deformation due to external forces. The presence of the reinforcing flange 120 effectively increases the moment of inertia of the lug 100 section, enhancing its resistance to bending and torsion. This structure exhibits excellent deformation suppression, especially under conditions of eccentric loading or misalignment, ensuring connection reliability.

[0070] The reinforced flange 120 and the reinforcing ribs 110 surrounding the hanging hole 101 work together to form a dual reinforcement system. The reinforcing ribs 110 are responsible for local reinforcement of key stress points, while the reinforced flange 120 provides global rigid support. Together, they optimize the load transmission path inside the hanging lug 100, making the stress distribution more uniform and reducing the risk of fatigue cracking.

[0071] The reinforcing fold 120 is formed in one step using cold stamping or bending, and is manufactured simultaneously with the lug 100 body, hanging hole 101, connecting part, and reinforcing rib 110, eliminating the need for subsequent welding or additional parts assembly. This integrated structure ensures the continuity of mechanical properties and the consistency of the manufacturing process, which is conducive to achieving automated mass production.

[0072] In some embodiments, the lug 100 has a reinforcing side 102 and a mounting side 103 arranged opposite to each other, with the reinforcing rib 110 and the reinforcing flange 120 located on the reinforcing side 102.

[0073] The mounting lug 100 has two functionally defined surfaces: a reinforcing side 102 and a mounting side 103, which are positioned opposite each other and face different external environments. The mounting side 103 faces the wall and is close to or directly opposite the wall after the water tank 20 is installed, serving to accommodate the connection operation between the mounting hole 101 and the wall hook; the reinforcing side 102 faces away from the wall and is exposed to the external space, serving to accommodate structural reinforcement features.

[0074] A reinforcing rib 110 is disposed on the reinforcing side 102 of the hanging lug 100, surrounding the edge of the hanging hole 101 to form a local rigid support structure. This rib is manufactured using a protrusion forming process on the reinforcing side 102 of a metal sheet, extending continuously circumferentially along the hanging hole 101, its outline matching the shape of the hanging hole 101. Because it is located on the back wall side, the reinforcing rib 110 does not contact the wall surface, preventing positioning obstruction or wall scratching during installation due to the protruding structure, thus ensuring smooth installation.

[0075] The reinforcing fold 120 is also located on the reinforcing side 102 of the lug 100, and is set along the outer periphery of the lug 100. It is formed into a vertical edge structure perpendicular to the substrate through bending or flanging processes. This fold extends continuously around the outline of the lug 100, forming a ring-shaped frame, which significantly improves the overall bending stiffness and torsional strength of the lug 100. The reinforcing fold 120 and the reinforcing rib 110 are set together on the back wall side, jointly constructing a composite reinforcement system facing external loads.

[0076] The reinforcing ribs 110 and reinforcing flanges 120 are concentrated on the reinforcing side 102 facing away from the wall, achieving a coordinated unity between structural reinforcement and installation compatibility. During the suspension of the water tank 20, the mounting side 103 directly faces the wall, and its surface is flat or has through holes 101 for easy alignment with the wall hooks and fastening. All protruding reinforcing structures are located on the side away from the wall to avoid installation difficulties or wall damage caused by interference from protrusions.

[0077] The reinforced side 102 serves as the main load-bearing surface, bearing the tensile force, shear force, and possible torsional moment from the weight of the water tank 20 when suspended. The reinforcing ribs 110 effectively disperse the concentrated stress at the edge of the hanging hole 101, preventing deformation or tearing around the hole; the reinforced folded edge 120 enhances the overall structural stability of the hanging ear 100, suppresses out-of-plane deflection, and ensures connection reliability during long-term use.

[0078] In some embodiments, the ear loop 100 is provided with an insulating layer that covers the outer surface of the ear loop 100.

[0079] The lug 100 is provided with an insulating layer that covers the entire outer surface of the lug 100, forming a complete electrical isolation barrier. This insulating layer is integrally formed on the outside of the metal substrate through plastic coating or injection molding processes, wrapping the reinforcing side 102, mounting side 103, edge folds, the periphery of the hanging hole 101, and all exposed metal areas of the lug 100, ensuring that users will not directly touch conductive parts during installation, maintenance, or daily contact, effectively preventing the risk of leakage.

[0080] The insulation layer is made of thermoplastic engineering plastic material, which has good electrical insulation properties, resistance to damp heat aging, and mechanical adhesion. Commonly used materials include polypropylene (PP), polyamide (PA), or thermoplastic elastomer (TPE), with a volume resistivity of not less than 10¹¹ Ω·cm and a dielectric strength greater than 15kV / mm, meeting the safety standards for household appliances in humid environments.

[0081] The molding process of the insulation layer is matched with the structural features of the lug 100. During injection molding, the molten plastic material fully fills the gaps between the reinforcing ribs 110 and the reinforcing flanges 120 on the reinforcing side 102, achieving an interlocking bond between the structure and the insulation layer and improving the bonding strength. At the same time, the insulation layer forms a continuous cover on the inner edge of the hanging hole 101, avoiding exposed metal edges and ensuring that the insulation integrity is maintained when the connector is inserted.

[0082] The insulation layer has a uniform thickness between 0.8mm and 2.5mm, with appropriate thickening in key stress areas such as around the hanging hole 101 and at the corners and edges to enhance wear resistance and impact resistance. This thickness effectively blocks current conduction without affecting the installation gap between the hanging ear 100 and the wall due to excessive thickness, ensuring smooth hanging operation.

[0083] Since the mounting side 103 of the hook 100 faces the wall, after the insulation layer is applied, the surface of this side is smooth and without sharp protrusions, so it will not scratch the wall or interfere with the hook alignment. The reinforced side 102, which faces away from the wall, is the area accessible to the user. The insulation layer fully covers the edges of the reinforcing ribs 110 and the reinforcing folded edges 120 on this side, achieving a passivation treatment, which significantly improves human and machine safety and prevents scratches during handling or maintenance.

[0084] The insulating layer and the metal substrate of the lug 100 are firmly bonded together through mechanical anchoring and molecular-level bonding. Before injection molding, the metal surface is cleaned, activated, or sandblasted to improve the interfacial adhesion. In some embodiments, the lug 100 body has grooves, through holes, or stepped structures to enhance the interlocking effect between the plastic and the metal and prevent delamination or peeling during long-term use.

[0085] Please see Figures 2 to 4This application provides a water tank 20, which includes an inner liner 400 and an installation structure 10 as described in any of the above embodiments. The inner liner 400 has a connected top liner 410 and a back liner 420. The installation structure 10 is connected to the top liner 410 and the back liner 420 and is disposed near the connection between the top liner 410 and the back liner 420.

[0086] The water tank 20 is a core component of the water heater, used to store and heat domestic water. Its structural design directly affects the energy efficiency, safety, and ease of installation of the equipment. This application provides a water tank 20, which includes an inner tank 400 and an installation structure 10 as described in any of the aforementioned embodiments. The inner tank 400 is formed by welding metal sheets, and has an overall rectangular or near-rectangular structure, possessing good sealing performance and pressure resistance.

[0087] The inner liner 400 includes a top plane and a vertical back plane, which intersect above and behind the water tank 20 to form a connecting edge extending laterally. This connecting area possesses high structural rigidity and resistance to deformation due to the orthogonal connection of the two metal plates, making it suitable as a primary load-bearing component. The mounting structure 10 is positioned near this connecting area, fully utilizing the structural advantages of the inner liner 400 to achieve a stable and reliable suspension connection.

[0088] The mounting structure 10 is fixedly connected to the top 410 plane of the inner tank via the first connecting part 200 and to the back 420 plane of the inner tank via the second connecting part 300, forming a double-sided welded composite connection. The two connecting parts are completely fitted to the metal surface of the inner tank 400, achieving metallurgical bonding through argon arc welding, laser welding, or resistance welding. The weld is continuous and complete, possessing sufficient tensile strength and shear resistance, and can withstand the suspended load of the water tank 20 under full load for extended periods.

[0089] The mounting structure 10 is positioned close to the junction of the inner tank top 410 and the inner tank back 420, without extending to the center of the large flat area of ​​the back. This layout avoids forming a raised structure on the main surface of the back, keeping the inner tank back 420 flat and smooth, providing an unobstructed base surface for the continuous adhesion of the vacuum insulation panel. As a highly efficient insulation material, the vacuum insulation panel can cover the back and the other five outer surfaces in one sheet, reducing splicing gaps, suppressing thermal bridging effects, and significantly improving the overall insulation performance of the water tank 20.

[0090] This application provides a water heater comprising a water tank 20 and a heating element as described in any of the above embodiments. The heating element is used to heat the water in the water tank 20.

[0091] The water tank 20 serves as a heat storage unit to hold the water to be heated; the heating element serves as an energy conversion device to directly heat the water inside the water tank 20, achieving rapid heating and constant temperature maintenance.

[0092] The water tank 20 adopts a high-strength structural design, including a metal inner liner 400, an insulation layer, and an outer shell. The inner liner 400 is made of stainless steel or enamel-coated steel plate, possessing excellent corrosion resistance and sealing performance. The inner liner 400 has an interconnected top plane and a vertical back plane, with an installation structure 10 provided at their junction. This installation structure 10 is connected to the top 410 of the inner liner via a first connecting part 200 and to the back 420 of the inner liner via a second connecting part 300, forming a double-sided fixed support to ensure structural stability during suspension.

[0093] The heating element is located inside the water tank 20, extending into the water cavity to directly contact the water and conduct heat. The heating element is in the form of a heating tube, with the resistance wire encapsulated in a metal shell and filled with a highly thermally conductive insulating material, providing excellent heating efficiency and long-term reliability. The heating element is arranged vertically, penetrating from the lower to the middle section of the water tank 20, enabling effective heating under different water levels and improving thermal energy utilization.

[0094] The heating element is fixed to the side wall or bottom of the water tank 20 via a sealing flange or threaded interface. A high-temperature resistant sealing ring is provided at the interface to prevent water leakage from the mounting hole. The lead-out terminals are located outside the water tank 20 and are connected to the control module via insulated wires to receive start / stop signals and power adjustment commands, achieving precise temperature control.

[0095] The outer surface of the water tank 20 is covered with a high-efficiency insulation layer, which adopts a composite structure of vacuum insulation board and foam layer to minimize heat loss. Since the installation structure 10 is located in the connection area between the top 410 of the inner tank and the back, it does not form a protrusion in the center of the large plane of the back. The insulation layer can be continuously and completely pasted on this plane, avoiding thermal bridging problems caused by cutting and splicing, and further improving the overall insulation performance of the machine.

[0096] The water heater is equipped with a control system that automatically starts and stops the heating element based on the user-set temperature and the actual water temperature in the tank. The water heater also integrates a temperature sensor, a safety temperature limiter, and a leakage protection device to ensure timely power cut-off in abnormal operating conditions and guarantee safe use.
