Obviously, the described embodiments are a part of the embodiments of the present application, but not all the embodiments of the present application.

[0035] Referring to Figure 1 The embodiment of the present application provides an electric water heater 10, which comprises a water tank 100, a hanger 200, a hanging plate 300 and an insulating support 20. The hanger 200 is fixedly connected to the outer side of the water tank 100, and is usually firmly assembled by welding or other reliable mechanical connection mode, for supporting the overall weight of the electric water heater 10 and realizing the function of suspension installation. The hanging plate 300 is arranged in an installation environment, such as a wall surface, and is firmly installed at a specified position by expansion bolts 700, embedded parts or other fixing structures, for bearing the electric water heater 10 and realizing the suspension connection through the hanger 200. In the use state, the hanging plate 300 is connected with the installation environment and connected with the hanger 200 through the insulating support 20, so as to improve the safety performance of the electric water heater 10.

[0036] Referring to Figure 3The embodiment of the present application provides an insulating support 20 which is integrally injection molded by using a polymer insulating material, has good electrical insulation performance and mechanical strength, can effectively isolate the current conduction path between the hanger 200 and the hanging plate 300, and prevent the occurrence of safety hazards such as electric leakage, short circuit or flashover. The polymer insulating material is preferably an engineering plastic such as polypropylene (PP), polyamide (PA) or polyethylene terephthalate (PET) which has good heat resistance, aging resistance and processing performance, so as to meet the long-term stable operation requirement of the electric water heater 10 in a complex environment such as humidity, high temperature and dust accumulation.

[0037] Please refer to Figure 1 、 Figure 2 and Figure 4 , the insulating support 20 can include a support body 400, the support body 400 has a first abutting surface 410, a second abutting surface 420 and a connecting surface 430, the first abutting surface 410 is in abutment with the hanger 200 in the use state, the second abutting surface 420 is in abutment with the hanging plate 300 in the use state, the first abutting surface 410 and the second abutting surface 420 are respectively located on opposite sides of the support body 400, the connecting surface 430 is connected to the first abutting surface 410 and the second abutting surface 420, and is separated from the hanger 200 and the hanging plate 300, and the connecting surface 430 is provided with a profile adjusting portion 440, the profile adjusting portion 440 is configured to increase the surface distance between the hanger 200 and the hanging plate 300.

[0038] In this way, the profile adjusting portion 440 is arranged on the connecting surface 430, and the profile adjusting portion 440 is configured to change the surface form of the connecting surface 430, thereby prolonging the surface current path length between the hanger 200 and the hanging plate 300, that is, increasing the creepage distance, while ensuring sufficient creepage distance, effectively reducing the overall size of the insulating support 20, and improving the installation space utilization,

[0039] It can be understood that the creepage distance refers to the shortest path length between two conductive components (i.e., between the hanger 200 and the hanging plate 300) measured along the surface of the insulating material. Increasing the surface distance between the hanger 200 and the hanging plate 300 is to increase the creepage distance. In the process of installing the electric water heater 10, the first abutting surface 410 is used to contact and fit with the hanger 200 of the electric water heater 10, and the second abutting surface 420 is used to contact and fit with the hanging plate 300, and the first abutting surface 410 and the second abutting surface 420 are respectively located on opposite sides of the support body 400. The connecting surface 430 is connected between the first abutting surface 410 and the second abutting surface 420, and is arranged in a spaced-apart manner from the hanger 200 and the hanging plate 300, forming a non-contact area.

[0040] Please refer to Figures 3 to 5In some embodiments, the profile adjustment portion 440 is a groove. The profile adjustment portion 440 is a groove structure formed on the connecting surface 430. The groove is arranged along the surface of the connecting surface 430, and can have a linear shape, a curved shape, a zigzag shape, or other suitable shape suitable for extending the creepage path. The arrangement of the groove changes the surface continuity of the connecting surface 430 of the insulating support 20, so that the originally flat surface current path is forced to bypass the groove wall, thereby significantly increasing the creepage distance.

[0041] The groove is directly formed on the connecting surface 430 of the support body 400 by a mold injection molding process. The support body 400 is integrally formed by using a high-molecular insulating material, and has good electrical insulation performance and mechanical strength. This structure not only improves the safety performance of the insulating support 20, but also avoids the problems of large size and limited installation space caused by the traditional design method of increasing the overall size to achieve the creepage distance, which is conducive to the miniaturization design and space optimization layout of the whole machine structure.

[0042] In some embodiments, the width of the groove is greater than 1 mm; and / or, the depth of the groove is greater than 1 mm. Specifically, when the width of the groove is greater than 1 mm, the current needs to pass through the groove when flowing through the connecting surface 430, forming a longer path; and when the depth of the groove is also greater than 1 mm, the degree of tortuosity of the path is further enhanced, making it more difficult for the leakage current to cross the groove area, thereby effectively suppressing the occurrence of leakage or flashover phenomenon.

[0043] In actual application, the width and depth of the groove can be reasonably set according to the installation environment, voltage level and relevant electrical safety standards of the electric water heater 10. Preferably, the width of the groove is 1.5-3 mm, and the depth is 1.5-2.5 mm, which can meet the design requirements of the creepage distance, and also does not affect the overall strength and manufacturing process of the insulating support 20.

[0044] In some embodiments, the cross section of the groove has a V-shaped outer profile. The V-shaped groove forms a groove body with an included angle through the inclined side walls on both sides, so that the current propagating along the surface of the support body 400 must bypass the bottom and side wall edge of the V-shaped groove, thereby significantly extending the creepage path length and improving the electrical insulation performance.

[0045] In some embodiments, the profile adjustment portion 440 has a first groove wall and a second groove wall opposite and connected to each other, and the included angle between the first groove wall and the second groove wall is greater than 0 degrees and less than 80 degrees.

[0046] When the included angle is greater than 0 degrees and less than 80 degrees, the current must propagate along a tortuous path between the first groove wall and the second groove wall, thereby greatly improving the insulation performance. Especially in harsh environments such as humidity, dust, etc., the contour adjusting portion 440 can effectively prevent surface leakage and flashover phenomena, ensuring long-term stable electrical isolation between the electric water heater 10 hanger 200 and the hanging plate 300.

[0047] In addition, the V-shaped groove structure in this angle range has good structural strength while maintaining good electrical performance. Compared to a right-angle groove or a U-shaped groove, the inclined side walls at the bottom of the V-shaped groove help to disperse stress distribution under external force, reducing the risk of local fracture, thereby enhancing the overall carrying capacity and service life of the insulation support 20.

[0048] In some embodiments, the contour adjusting portion 440 is a protruding rib. The cross-sectional shape of the protruding rib can be triangular, trapezoidal, semicircular, or other geometric forms suitable for enhancing the creepage distance.

[0049] The number of protruding ribs can be set to one or more as needed, and can be arranged in parallel or staggered along the length direction of the connecting surface 430 to further enhance the effect of increasing the creepage distance. The spacing between multiple protruding ribs can also form multiple isolated current path areas, preventing current from crossing between different areas and improving overall insulation reliability.

[0050] The protruding rib is directly integrated on the connecting surface 430 of the support body 400 by an integral injection molding process of high molecular insulation material, having good structural strength and processing consistency.

[0051] In addition, the protruding rib structure not only extends the creepage distance, but also to some extent enhances the local mechanical rigidity of the support body 400, improving its anti-deformation ability when subjected to external loads, thereby further ensuring the stability of the connection between the hanger 200 and the hanging plate 300.

[0052] In some embodiments, the height of the protruding rib is greater than 2 mm. When the height of the protruding rib exceeds 2 mm, the current must pass through the top of the protruding rib when flowing through the connecting surface 430, forming a more tortuous surface path, which can achieve a higher electrical safety level without increasing the overall size of the insulation support 20.

[0053] Further, the height of the protruding rib is preferably 2.5-4 mm. Within this range, the protruding rib can effectively enhance the creepage distance without affecting the overall structural strength and installation stability of the support body 400. At the same time, this height range is also conducive to the smooth implementation of the injection molding process, avoiding product defects due to difficult demolding or stress concentration.

[0054] In some embodiments, the insulating support 20 further comprises a nut mounting portion 500 and a nut 600, the nut mounting portion 500 is connected to the support body 400, the nut mounting portion 500 and the first side surface cooperate to clamp the hanger 200, and ensure the stable connection between the support body and the hanger 200.

[0055] The nut mounting portion 500 and the nut 600 are integrally injection molded. The nut mounting portion 500 is provided with a mounting cavity for accommodating the nut 600, the nut 600 is embedded in the mounting cavity, and the nut mounting portion 500 and the nut 600 are manufactured by an integral injection molding process. The nut mounting portion 500 not only improves the connection strength between the nut 600 and the insulating support 20, but also effectively prevents the nut 600 from loosening or falling off during use, and improves the reliability and service life of the overall assembly.

[0056] Further, the nut 600 is made of a metal material to meet the mechanical strength requirements of threaded connection, and the outside is completely covered in a high polymer insulating material, thereby achieving good electrical isolation effect. This plastic-coated structure avoids the risk of electric leakage that may be caused by direct exposure of the metal nut 600 to the environment, and also helps to improve the safety performance of the whole machine.

[0057] In some embodiments, the extension direction of the profile adjusting portion 440 is perpendicular to the thickness direction of the support body 400. This arrangement ensures that the profile adjusting portion 440 (such as a groove or a protrusion) extends along the width direction of the support body 400, thereby forming a transversely distributed creeping path extension structure between the hanger 200 and the mounting plate 300, which helps to more effectively increase the path length of the current propagating along the insulating surface.

[0058] Specifically, the thickness direction of the support body 400 is the direction of the distance between the first abutting surface 410 and the second abutting surface 420, i.e. the main transmission direction of the pressure borne by the insulating support 20 in the installed state; and the profile adjusting portion 440 extends perpendicular to this direction, so that it is linearly arranged on the connecting surface 430, which can guide the current to propagate in a longer transverse path, avoiding the risk of the current directly crossing the shortest distance between adjacent conductive components.

[0059] Preferably, the profile adjusting portion 440 (such as a groove or a protrusion) continuously extends or is arranged in intervals along the width direction of the support body 400, and its extension length can be adjusted according to actual needs to match different sizes and electrical performance requirements of the electric water heater 10 product. This structure not only improves the enhancement effect of the creeping distance, but also facilitates the realization of the mold forming process, improves the production efficiency and product consistency.

[0060] In addition, the extending direction of the profile adjusting portion 440 is designed to be perpendicular to the thickness direction of the support body 400, which can also enhance the mechanical strength of the support in some extent. Since the profile adjusting portion 440 is usually located in the middle of the support or near the stress area, the lateral extending structure can help to disperse the stress distribution under the external load, prevent the structure from being damaged due to local stress concentration, and thus improve the stability and reliability of the insulation support 20 during long-term use.

[0061] In some embodiments, the number of profile adjusting portions 440 is multiple, and each profile adjusting portion 440 is independently arranged. The multiple profile adjusting portions 440 are arranged in the extending direction of the connecting surface 430 and are spaced apart from each other or arranged according to actual needs. The profile adjusting portions 440 are independent of each other and each play a role in extending and blocking the current path, thereby further enhancing the creepage distance and improving the insulation performance.

[0062] Each profile adjusting portion 440 can be a groove, a protruding rib, or other structural forms capable of changing the surface current path form. The arrangement of the multiple profile adjusting portions 440 makes the current flow through the insulation surface have to pass through each structure in turn, forming a multi-segment winding path. Compared with a single structure, the effect of extending the creepage distance is more significant, and it is particularly suitable for electrical isolation requirements in high-voltage grades or harsh environments.

[0063] Preferably, the multiple profile adjusting portions 440 are uniformly spaced apart in the width direction or the length direction of the support body 400 to ensure the continuity and stability of the current path. At the same time, this arrangement is also conducive to the realization of the mold injection molding process, improving the production efficiency and product consistency. In some application scenarios, the number and layout of the profile adjusting portions 440 can be flexibly adjusted according to the specific shape and installation space limitation of the electric water heater 10 hanging rack 200 structure to achieve the best electrical safety effect.

[0064] In addition, the multiple independently arranged profile adjusting portions 440 also have good fault tolerance. Even if the local insulation performance of a certain area is reduced due to pollution, moisture, or wear, the remaining profile adjusting portions 440 can still continue to function to maintain the overall electrical isolation capability and prevent the occurrence of electric leakage or flashover.

[0065] In some embodiments, the profile adjusting portion 440 is arranged around the edge of the connecting portion of the first abutting surface 410 and the second abutting surface 420, so that the profile adjusting portion 440 can cover the peripheral area between the hanging rack 200 and the hanging plate 300 where surface electric leakage is most likely to occur, and form an effective blocking structure on the main path of current propagation, thereby significantly extending the creepage distance and improving the electrical insulation performance.

[0066] In some embodiments, the electric water heater 10 further comprises a bolt 700, which can pass through the hanging plate 300, the bracket body 400 and the bracket 200 at one time and cooperate with the nut 600 to realize fastening connection, so as to ensure the stable assembly between the bracket 200 and the hanging plate 300.

[0067] In some embodiments, the electric water heater 10 further comprises a heating assembly, a heat preservation layer, a shell, water inlet and outlet pipelines and a control system. The water tank 100 is used for storing and heating cold water, which is usually made of metal material and coated with a heat preservation layer outside to reduce heat loss. The heating assembly is arranged inside or at the bottom of the water tank 100 and electrically connected with the control system, and is used for heating water in the water tank 100. The control system comprises a temperature controller, a leakage protection device and other components, and is used for intelligently controlling and safely protecting the heating process.
