[0047] An electric water heater is a type of water heater that uses electricity as its primary energy source. The high-temperature heat generated after the power is turned on directly heats the water stored in the water heater to produce hot water.

[0048] Electric water heaters typically consist of a water tank, an electric heating element, and an electronic control board. The water tank has a storage cavity to store water to be heated. The electric heating element is inserted into the storage cavity of the water tank. The electronic control board is used to control the electric heating element to operate by turning the power on and off, so that the water in the tank is heated to the set temperature.

[0049] For the water tank of an electric water heater, the tank generally consists of an outer shell and an inner tank, with an insulation layer between them. The outer shell is usually made of plastic to meet the requirements of aesthetic and diverse designs; the inner tank can be made of metal or plastic, depending on the needs.

[0050] In addition, the insulation layer formed between the outer shell and the inner liner is commonly made of materials such as asbestos, sponge, foam plastic, and polyurethane foam. In conventional technology, foaming is usually used to form the insulation layer in order to achieve good insulation effect.

[0051] For water tanks with metal inner liner, corrosion can easily occur inside due to water quality. Therefore, magnesium rods are installed on the water tank and inserted into the water storage cavity inside the tank.

[0052] Magnesium has the lowest electrochemical potential among metals and is physiologically non-toxic. Therefore, it is ideal for making magnesium rods to protect the inner liner. The size of the magnesium rod directly affects the duration and effectiveness of the protection; the larger the magnesium rod, the better the protection and the longer the protection time.

[0053] The water tank is also equipped with an inlet pipe and an outlet pipe. The inlet pipe is used to deliver cold water into the water storage cavity formed inside the water tank, while the hot water in the water storage cavity is output from the outlet pipe.

[0054] For electric heating components, electric heating methods such as electric heating wires, magnetic energy, or silicon tube heating can be used to heat the water stored in the water storage chamber.

[0055] The control board is used to receive detection signals from relevant sensors (such as water temperature sensors and flow sensors) and control the power supply to and from the electric heating components.

[0056] When the electric water heater is working, the electric control board controls the electric heating element to be powered on and heated. When the water temperature in the tank reaches the set value, the electric control board controls the electric heating element to be powered off.

[0057] In some embodiments of this application, an electric water heater is provided, with reference to... Figure 1 The electric water heater includes a casing 100.

[0058] The electric water heater also includes an anti-electric shock wall cover 200. Figure 13 This is a structural diagram of an anti-electric shock wall cover 200. Figure 14 for Figure 13 Enlarged view of section F. The anti-electric shock wall cover 200 is fixedly installed on the outer casing 100 by means of clips, screws, etc. The anti-electric shock wall cover 200 is provided with an opening 210, which extends along the length of the anti-electric shock wall cover 200.

[0059] The electric water heater also includes a control panel assembly 300. Figure 7 This is a structural diagram of control panel component 300. Figure 8 for Figure 7 Enlarged view of section D in the middle.

[0060] Control panel component 300 includes control panel 310. Figure 11 This is a structural diagram of control panel 310. Figure 12 for Figure 11 Enlarged view of section E. The control panel 310 has a long, narrow structure.

[0061] The control panel component 300 also includes a decorative strip 320, which is mounted on the control panel 310. The control panel 310 and the decorative strip 320 are made of different materials.

[0062] The control panel 310 is connected to the anti-electric shock wall cover 200 to achieve fixed installation of the control panel assembly 300 on the anti-electric shock wall cover 200. For example, the control panel 310 is fixed to the anti-electric shock wall cover 200 by a snap-fit ​​method, eliminating the need for multiple screws in the prior art. The snap-fit ​​structure is more convenient and facilitates the installation of the control panel 310, thus improving installation efficiency.

[0063] For example, multiple sliding positioning structures 10 and multiple snap-fit ​​fixing structures 20 are provided between the control panel 310 and the anti-electric wall cover 200 for assembly and fixing.

[0064] During installation, the decorative strip 320 is first installed onto the control panel 310 to form the control panel assembly 300. Then, the control panel 310 is installed onto the anti-electric wall cover 200 to achieve the fixed installation of the control panel assembly 300 on the anti-electric wall cover 200.

[0065] In existing technologies, the control panel of electric water heaters is entirely made of plastic, resulting in a monotonous material that can easily cause visual fatigue for users. This invention, however, incorporates a control panel assembly 300 that combines the control panel 310 with a decorative strip 320, using different materials from the control panel 310. This combination of different materials enriches the visual appeal of the control panel 310, breaking the monotony of a single material and giving the water heater a more stylish and high-quality appearance. This effectively enhances the user's visual experience, prevents visual fatigue, and strengthens the product's market competitiveness.

[0066] In this invention, multiple sliding positioning structures 10 and multiple engaging fixing structures 20 are provided between the control panel 310 and the anti-electric shock wall cover 200. The sliding positioning structures 10 provide precise positioning during assembly, guiding the control panel 310 to quickly and accurately align with the anti-electric shock wall cover 200, reducing adjustment time and improving assembly efficiency. The engaging fixing structures 20 ensure a stable connection after positioning, guaranteeing the connection strength and structural stability between the control panel 310 and the anti-electric shock wall cover 200. The combination of these two features makes the assembly process of the control panel 310 and the anti-electric shock wall cover 200 more convenient and efficient, while ensuring the structural reliability after assembly, reducing assembly difficulty and production costs, and ultimately improving production efficiency.

[0067] In summary, this utility model of electric water heater, through structural improvements to the control panel component 300 and optimization of the assembly structure, not only improves the product's visual appearance and enhances the user experience, but also increases the ease of assembly and the stability of the structure.

[0068] In some embodiments of this application, the control panel 310 is a non-metallic component, and the decorative strip 320 is a metallic component. For example, the control panel 310 is a plastic component, and the decorative strip 320 is an aluminum alloy component.

[0069] The control panel 310 uses non-metallic components (such as plastic) to meet the insulation requirements when in contact with the display panel, ensuring electrical safety during the use of the electric water heater and avoiding the risk of electric shock caused by the conductivity of the control panel 310.

[0070] The metallic decorative strip 320 (such as aluminum alloy parts) contrasts sharply with the non-metallic control panel 310 (such as plastic parts). The metallic decorative strip 320 has a unique metallic luster and texture, adding a sense of luxury and sophistication to the appearance of the electric water heater, while the plastic control panel 310 can be made into various shapes and colors through injection molding and other processes. The combination of the two makes the visual effect of the control panel 310 area richer and more three-dimensional, breaking the monotony of a single material and significantly improving the appearance quality and grade of the product, better meeting users' needs for the aesthetics of home appliances.

[0071] The combination of the metal decorative strip 320 and the non-metallic control panel 310 can also create a unique design style through the difference in materials, making the electric water heater more recognizable among similar products on the market. For example, the metallic texture of the aluminum alloy decorative strip 320 can highlight the product's technological and modern feel, contrasting and balancing with the soft texture of the plastic control panel 310, further enhancing the product's market competitiveness and meeting the diverse needs of different users for the appearance style of home appliances.

[0072] In addition, the metal decorative strip 320 is fixedly installed on the non-metallic control panel 310, and the decorative strip 320 also helps to improve the structural strength of the control panel 310.

[0073] In some embodiments of this application, reference is made to Figure 3 The decorative strip 320 has a labeling area 321. For example, the labeling area 321 displays information such as the product's trademark and model number.

[0074] The trademark, model and other information are integrated into the identification area 321 of the decorative strip 320, which is coordinated with the different materials of the decorative strip 320 and the control panel 310. This ensures that the key information is clearly displayed without compromising the overall aesthetic appearance of the electric water heater.

[0075] In some embodiments of this application, reference is made to Figure 2 and Figure 3 The decorative strip 320 is located on the upper edge of the control panel 310. The decorative strip 320 includes a first sub-decorative strip 3211 and a second sub-decorative strip 3212. Figure 9 This is a structural diagram of the first sub-decorative strip 3211. Figure 10 This is a structural diagram of the second sub-decorative strip 3212. The first sub-decorative strip 3211 and the second sub-decorative strip 3212 extend along the length of the control panel 310, and the second sub-decorative strip 3212 is provided with an identification area 321.

[0076] The decorative strip 320 is located at the upper edge of the control panel 310, a position that aligns with users' visual habits when observing an electric water heater. When operating or viewing the water heater, users' eyes tend to focus first on the upper area of ​​the control panel 310, allowing the decorative strip 320 to more directly fulfill its decorative function. The first sub-decorative strip 3211 and the second sub-decorative strip 3212 extend along the length of the control panel 310, adapting to its overall shape. The combined design of the two sub-decorative strips 320 further enriches the visual hierarchy of the upper part of the control panel 310. For example, if the first sub-decorative strip 3211 and the second sub-decorative strip 3212 use different materials, colors, or surface treatments, their length-extending layout creates a horizontal visual contrast and harmony, enhancing the decorative effect while avoiding the monotony of a single decorative strip 320, making the electric water heater's appearance more stylish and refined.

[0077] The identification area 321 is positioned on the second sub-decorative strip 3212. Combined with the fact that the decorative strip 320 is located at the upper edge and the second sub-decorative strip 3212 extends along its length, the identification area 321 becomes more prominent. Users can quickly find the trademark, model number, and other information in the identification area 321 without having to search for it, further improving the efficiency of information transmission. Simultaneously, concentrating the identification area 321 on the second sub-decorative strip 3212 creates a functional distinction from the first sub-decorative strip 3211. The first sub-decorative strip 3211 primarily serves a decorative and aesthetic purpose, while the second sub-decorative strip 3212 combines decoration with information display. This division of labor ensures the independence and clarity of the identification area 321, while the coordinated operation of the two sub-decorative strips 320 makes the upper area of ​​the control panel 310 visually more harmonious and unified.

[0078] The separate design of the first sub-decorative strip 3211 and the second sub-decorative strip 3212 allows for flexible selection of different processing techniques and installation methods according to actual production needs. For example, if the second sub-decorative strip 3212 requires special materials or processing (such as printing, engraving, etc.) to set up the marking area 321, the separate design can reduce the manufacturing difficulty and cost of the overall decorative strip 320; in subsequent maintenance, if the marking area 321 is worn or damaged, the second sub-decorative strip 3212 can be replaced separately without replacing the entire decorative strip 320, reducing maintenance costs and operational complexity.

[0079] Furthermore, the layout extending along the length of the control panel 310 allows the first sub-decorative strip 3211 and the second sub-decorative strip 3212 to form a more complete wrap or decoration around the upper edge of the control panel 310, enhancing the structural aesthetics of the edge of the control panel 310. At the same time, it can, to a certain extent, shield the connection edge between the control panel 310 and the anti-electric wall cover 200, improving the overall appearance and sophistication of the electric water heater.

[0080] In some embodiments of this application, reference is made to Figure 9 The first sub-decorative strip 3211 is provided with a first connecting part 3251. (See reference...) Figure 10 The second sub-decorative strip 3212 is provided with a second connecting portion 3252. The first connecting portion 3251 is connected to the second connecting portion 3252 to realize the connection between the first sub-decorative strip 3211 and the second sub-decorative strip 3212. For example, the first connecting portion 3251 is a slot and the second connecting portion 3252 is a hook.

[0081] The use of a slot and hook connection structure enables rapid docking and assembly of the first sub-decorative strip 3211 and the second sub-decorative strip 3212. During the production assembly process, the operator only needs to align the hook of the second sub-decorative strip 3212 with the slot of the first sub-decorative strip 3211 and apply appropriate pressure to complete the connection and fixation of the two. No additional tools are required, which simplifies the assembly process, improves assembly efficiency, and helps reduce production time and labor costs.

[0082] If the first sub-decorative strip 3211 or the second sub-decorative strip 3212 needs to be replaced or repaired in the future, the connection structure between the slot and the hook is easy to disassemble. Operators can use appropriate external force to disengage the hook from the slot, thus separating the two sub-decorative strips 320 without damaging the strip itself, reducing maintenance difficulty. For example, when the marking area 321 of the second sub-decorative strip 3212 shows wear and needs replacement, the second sub-decorative strip 3212 can be easily removed for replacement, while ensuring the integrity of the first sub-decorative strip 3211, reducing unnecessary material waste and lowering maintenance costs.

[0083] Furthermore, this connection structure ensures the integrity and aesthetics of the two sub-decorative strips 320 after connection. The slots and hooks fit tightly, minimizing noticeable gaps or protrusions at the joint of the two sub-decorative strips 320. This makes the decorative strips 320 look more harmonious and unified, matching the upper edge layout of the control panel 310, further enhancing the refined appearance of the electric water heater and improving the user's visual experience.

[0084] In some embodiments of this application, reference is made to Figure 9 or Figure 10 The decorative strip 320 includes a first decorative strip 3231 and a second decorative strip 3232. The first decorative strip 3231 is located above the second decorative strip 3232, and a step 324 is formed between the first decorative strip 3231 and the second decorative strip 3232. The first decorative strip 3231 is located on the upper side of the control panel 310, and the step 324 abuts against the upper edge of the control panel 310. The second decorative strip 3232 is located on the inner side of the control panel 310 and is connected to the control panel 310.

[0085] The decorative strip 320 of this application includes a first part 3231 and a second part 3232, with a step 324 formed between them. The first part 3231 is located on the upper side of the control panel 310, the step 324 abuts against the upper edge of the control panel 310, and the second part 3232 is located on the inner side of the control panel 310 and connected to it.

[0086] The abutment structure between step 324 and the upper edge of control panel 310 provides precise positioning. During the assembly of decorative strip 320, operators can quickly determine the accuracy of its installation position by observing the fit between step 324 and the upper edge of control panel 310, reducing positional deviations and improving assembly precision. Simultaneously, decorative strip part 3232 is located inside and connected to control panel 310, forming a double-fixed structure with decorative strip part 3231 covering the outside. This structure firmly secures decorative strip 320 to control panel 310, effectively resisting external forces that may occur during use (such as accidental user touch or slight vibration), preventing loosening, displacement, or detachment of decorative strip 320, significantly improving the stability of the connection between decorative strip 320 and control panel 310, and ensuring the reliability of the overall structure.

[0087] The decorative strip 3231 is located on the upper side of the control panel 310, effectively covering the upper edge area of ​​the control panel 310, while the step 324 abuts against the upper edge of the control panel 310, eliminating the gap between them. This design not only makes the connection between the decorative strip 320 and the control panel 310 tighter and the transition more natural, reducing the visual discontinuity, but also enhances the overall appearance and refinement.

[0088] The design of decorative strip part 3232 located inside the control panel 310 hides the connecting structure internally, preventing connecting parts (such as screws, clips, etc.) from being directly exposed and affecting the appearance. This concealed connection design, together with the external decoration of decorative strip part 3231, makes the control panel 310 area of ​​the electric water heater present a simpler and more integrated visual effect.

[0089] In some embodiments of this application, reference is made to Figure 9 and Figure 10 The decorative strip 3232 has multiple positioning holes 326, which are spaced apart along the length of the decorative strip 320. (Refer to...) Figure 11 and Figure 12 The control panel 310 is provided with a plurality of positioning posts 314, which are arranged at intervals along the length of the control panel 310. (Refer to...) Figure 8 The positioning post 314 is inserted into the corresponding positioning hole 326, and the positioning post 314 is heat-fused to fix the decorative strip 320 to the control panel 310.

[0090] Multiple positioning holes 326 are provided on the second part 3232 of the decorative strip, and multiple positioning posts 314 are provided on the control panel 310 accordingly. The decorative strip 320 is fixed to the control panel 310 by inserting the positioning posts 314 into the positioning holes 326 and fixing them by heat fusion.

[0091] The positioning holes 326 and positioning posts 314 work together to form a precise pre-positioning structure. During the initial assembly of the decorative strip 320 and control panel 310, the operator only needs to insert each positioning post 314 into the corresponding positioning hole 326 to quickly determine the accurate position of the second part of the decorative strip 3232 relative to the control panel 310, avoiding problems such as offset or skewing during assembly. This pre-positioning function, in conjunction with the step 324 positioning structure of the decorative strip 320 itself, further improves the overall assembly accuracy, ensuring that the relative positions of the first part of the decorative strip 3231, the second part of the decorative strip 3232, and the control panel 310 meet design requirements, laying the foundation for subsequent stable fixing.

[0092] The hot-melt fixing method after the positioning post 314 is inserted into the positioning hole 326 can achieve a rigid connection between the two. During the hot-melt process, the positioning post 314 melts and tightly bonds with the inner wall of the positioning hole 326. After cooling, it forms a strong integrated structure, which significantly improves the connection strength between the decorative strip 320 and the control panel 310.

[0093] The heat-fused fixing structure is hidden in the connection area between the decorative strip part 3232 and the control panel 310, leaving no obvious fixing marks (such as screw heads, buckle protrusions, etc.) on the outside of the control panel 310. Combined with the covering effect of the decorative strip part 3231 on the upper side of the control panel 310, the appearance of the entire control panel 310 area is more concise and flat, avoiding the visual damage caused by external fixing structures and improving the appearance quality of the product.

[0094] In some embodiments of this application, reference is made to Figure 11 and Figure 12 The control panel 310 is equipped with multiple positioning hooks 311, each of which has an L-shaped latch structure. The latches of the multiple positioning hooks 311 face the same side. (Refer to...) Figure 13 and Figure 14 The anti-electric shock wall cover 200 is provided with multiple positioning openings 220, and the anti-electric shock wall cover 200 is provided with positioning protrusions 230 near the positioning openings 220. (Refer to...) Figure 4 and Figure 5 The positioning hook 311 is inserted into the positioning opening 220, and the control panel 310 moves along the first direction to engage the positioning hook 311 with the positioning protrusion 230.

[0095] When installing the control panel component 300, the positioning hook 311 is inserted into the positioning opening 220, and then the control panel 310 is moved along the first direction, which is parallel to the length direction of the control panel 310. As the control panel 310 moves, the positioning hook 311 engages with the corresponding positioning protrusion 230, thereby achieving the pre-positioning of the control panel 310 on the anti-electric wall cover 200.

[0096] Reference Figure 8 The decorative strip 320 is provided with a first clearance notch 3271, which is used to clearance the positioning hook 311.

[0097] The engagement of the positioning hook 311 and the positioning opening 220 forms a preliminary guiding and positioning structure, namely the sliding positioning structure 10 mentioned above. When assembling the control panel 310 and the anti-electric shock wall cover 200, the operator can quickly determine their relative positions by aligning the positioning hook 311 and inserting it into the positioning opening 220, avoiding significant positional deviations in the initial assembly stage. This preliminary positioning lays the foundation for subsequent snap-fit ​​fixing, reducing adjustment steps during assembly and improving assembly efficiency. Simultaneously, the distributed layout of multiple positioning hooks 311 and positioning openings 220 enables positioning from multiple points, further ensuring the relative positional accuracy between the control panel 310 and the anti-electric shock wall cover 200, ensuring that the control panel 310 accurately covers the opening 210 on the anti-electric shock wall cover 200.

[0098] After the positioning hook 311 is inserted into the positioning opening 220, the control panel 310 moves in the first direction to engage the positioning hook 311 with the positioning protrusion 230, forming a reliable mechanical locking structure. The positioning protrusion 230 acts as a block and limiter for the positioning hook 311, effectively preventing the positioning hook 311 from disengaging from the positioning opening 220, thereby firmly fixing the control panel 310 to the anti-electric wall cover 200.

[0099] In some embodiments of this application, reference is made to Figure 12 The control panel 310 is equipped with a latch 312. (See reference...) Figure 14 The anti-electric shock wall cover 200 is provided with a snap-fit ​​opening 260, and a snap-fit ​​protrusion 240 is provided on the side of the snap-fit ​​opening 260. (Refer to...) Figure 6 The hook 312 engages with the hook protrusion 240 via the hook opening 260. (See reference...) Figure 8 The decorative strip 320 is provided with a second clearance notch 3272, which is a clearance for the hook 312.

[0100] The control panel 310 is provided with multiple hooks 312, which are located on the side opposite to the orientation of the positioning hook 311. The engagement between the hooks 312 and the engaging protrusion 240 constitutes the aforementioned engaging and fixing structure 20. During installation, the control panel 310 and the anti-electric shock wall cover 200 are initially positioned by the positioning hook 311 and the positioning opening 220. After the control panel 310 moves into place in the first direction, the positioning hook 311 engages with the positioning protrusion 230, and the hooks 312 then engage with the engaging protrusion 240, thus fixing the control panel 310 and the anti-electric shock wall cover 200.

[0101] The "positioning first, then fixing" assembly sequence provides clear operational guidance. Operators first quickly achieve initial positioning using the positioning hook 311 and positioning opening 220. At this point, the control panel 310 is roughly in the correct position. Subsequently, simply engaging the latch hook 312 with the locking protrusion 240 completes the fixing process. This step-by-step operation reduces assembly difficulty and minimizes locking failures due to inaccurate positioning.

[0102] In some embodiments of this application, reference is made to Figure 11 The control panel 310 is provided with a first screw hole 313. (Refer to...) Figure 14 The anti-electric shock wall cover 200 is provided with a second screw hole 250. (Refer to...) Figure 6 A screw is inserted between the first screw hole 313 and the second screw hole 250. After the hook 312 is connected to the snap-fit ​​protrusion 240, the control panel 310 and the anti-electric wall cover 200 are further fixed by screws.

[0103] Reference Figure 11 In this embodiment, the control panel 310 is provided with two first screw holes 313, which are arranged at intervals along the length of the control panel 310.

[0104] The screw connection, along with the aforementioned positioning hooks 311 and snap-fit ​​structures 312, forms a multi-layered fixing system. The snap-fit ​​structure primarily achieves rapid positioning and initial fixing, while the screw connection further enhances the tightening effect. The two work together, complementing each other's strengths. The snap-fit ​​structure can distribute some of the external force borne by the screw, reducing the load on the threaded connection; the screw connection can mitigate the risk of loosening that may occur in the snap-fit ​​structure during long-term use, together constructing a comprehensive fixing defense. This multi-layered fixing design ensures that the connection between the control panel 310 and the anti-electric shock wall cover 200 remains stable under various operating conditions, significantly reducing the probability of failure due to connection failure.

[0105] In some embodiments of this application, multiple sliding positioning structures 10 are arranged at intervals around the opening 210. Multiple engaging fixing structures 20 are located on the same end side of the opening 210. Two screw fastening positions are distributed at opposite ends of the opening 210.
