Description

Technical Field

[0001] This utility model relates to the field of electric water heater technology, and in particular to an electric water heater and its anti-electric shock wall structure and outer shell assembly. Background Technology

[0002] The anti-electric shock wall cover is a plastic part installed at the front of the inner tank of the electric water heater. It has two main functions: first, to hide the inlet and outlet water insulation pipes and serve a decorative purpose; and second, to fix the display panel and control panel.

[0003] In the prior art, the anti-electric shock wall cover is usually fixed to the inner barrel of the outer shell with screws. In order to ensure that the anti-electric shock wall cover and the inner barrel of the outer shell fit well, the anti-electric shock wall cover and the inner barrel of the outer shell need to be initially positioned before fixing with screws to avoid misalignment of screw holes.

[0004] Reference Figure 1A and Figure 1B As shown, an "L"-shaped bent claw 1 is provided at the edge of the front panel of the anti-electric shock wall cover, and a locking hole 2 is opened on the outer shell barrel. The claw 1 is used to hook the inner wall of the outer shell barrel to achieve the initial positioning of the anti-electric shock wall cover and the outer shell barrel. However, when installing the anti-electric shock wall cover, because the structure of the claw 1 is bent, the size of the locking hole 2 opened on the outer shell barrel must be larger than the size of the claw 1 in order to insert the claw 1 into the locking hole 2. Therefore, when filling the gap between the outer shell barrel and the inner liner with foam insulation layer, because the area of ​​the locking hole 2 opened on the outer shell barrel is relatively large, the foam material is prone to overflow at the locking hole 2.

[0005] To prevent the foaming material from overflowing from the retaining hole 2, a baffle plate or baffle membrane needs to be installed on the inside of the outer shell. Of the above solutions, using a baffle plate not only increases costs, but also occupies space between the outer shell and the inner liner, reducing the amount of foaming material and affecting the insulation effect. Using a baffle membrane, however, can lead to foaming material overflowing from the retaining hole due to insufficient membrane strength, requiring subsequent cleaning and adding processing steps.

[0006] In addition, a display panel back cover is installed on the back of the anti-electric shock wall cover, and the display panel is mounted on the back cover. Currently, to reduce costs, the same model of display panel and display panel back cover is used in multiple products. However, each product has different functions, so the display panel will have pre-installed terminal plugs for all functions, and the display panel back cover will have correspondingly provided multiple cable outlet holes for leading out the signal wires from the terminal plugs. For example, refer to... Figure 2A and Figure 2BAs shown, the display panel is equipped with a first terminal plug 3, a second terminal plug 4, and a third terminal plug 5. Correspondingly, a first cable exit hole 6, a second cable exit hole 7, and a third cable exit hole 8 are provided on the rear shell of the display panel. In practical applications, the use of terminal plugs is selected based on the characteristics of each product. Some products use only one terminal plug, some use only two terminal plugs, and some use three terminal plugs. When all three terminal plugs are not used, unused cable exit holes will appear. This allows insects and other small creatures to enter the rear shell of the display panel through these unused exit holes, interfering with the display.

[0007] In view of the above, this utility model is hereby proposed. Utility Model Content

The receiving cavity is configured to install the display panel of the electric water heater, and the display panel is provided with multiple terminal plugs.

[0017] The display panel has a main cable outlet on its rear cover, which is configured to allow signal lines connected to at least one of the plurality of terminal plugs to pass through.

[0018] In some embodiments, a protrusion is provided on the side wall of the rear housing of the display panel, the protrusion being configured to correspond to the position of the plurality of terminal plugs, and the main cable outlet is provided on the protrusion.

[0019] In some embodiments, a plurality of ribs are provided on the bottom wall of the rear shell of the display panel at positions corresponding to the protrusion to form a plurality of spaced lead holes, the positions of the plurality of lead holes being configured to correspond one-to-one with the positions of the plurality of terminal plugs.

[0020] In some embodiments, the protrusion is integrally formed with the back cover of the display panel.

[0025] (1) The anti-electric wall structure of the electric water heater provided by this utility model has multiple straight-insertion positioning posts arranged at intervals along the length direction on the back of the front side panel. When installing the anti-electric wall structure, the straight-insertion positioning posts can be directly inserted into the positioning holes provided on the outer shell of the electric water heater along their extension direction, so that the opening size of the positioning hole does not need to be larger than the size of the straight-insertion positioning post. Then, when the straight-insertion positioning post is installed in the positioning hole, the outer wall of the straight-insertion positioning post abuts against the positioning hole, thereby achieving the purpose of preventing overflow without the need to set up a baffle plate or baffle film.

[0026] (2) The anti-electric wall structure of the electric water heater provided by this utility model can prevent overflow of material from occurring in the tiny gap between the straight-insertion positioning post and the positioning hole due to processing errors by setting a baffle rib along the back of the front side plate and surrounding the outside of the straight-insertion positioning post in the circumferential direction.

[0027] (3) The anti-electric wall structure of the electric water heater provided by this utility model prevents flying insects from entering by setting a total outgoing hole on the back shell of the display panel that allows the signal line to be connected to at least one of the multiple terminal plugs.

Detailed Implementation

[0047] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0048] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0049] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0050] As described in the background section, existing related technologies that use baffles to prevent overflow not only increase costs but also occupy space between the outer shell and the inner tank, leading to a reduction in foaming material and affecting insulation performance. Using baffle membranes to prevent overflow results in foaming material overflowing at the locking holes due to insufficient membrane strength, requiring subsequent cleaning and adding processing steps. Therefore, this invention provides an anti-electric shock wall structure for an electric water heater. Multiple insertable positioning posts are spaced along the length of the back of the front panel of the anti-electric shock wall cover. During installation, these posts can be directly inserted into positioning holes on the outer shell of the water heater, eliminating the need for the positioning holes to be larger than the posts. Once the posts are in place, their outer walls abut against the holes, preventing overflow without the need for baffles or membranes.

[0051] The preferred technical solutions of the electric water heater 100, its anti-electric shock wall structure 20, and its outer casing assembly provided by this utility model are described below with reference to the accompanying drawings.

[0052] Figure 3 This is a structural schematic diagram of an electric water heater 100 provided by this utility model; Figure 4 yes Figure 3 The main view of the structure; Figure 5 yes Figure 4 Sectional view along line AA in the middle; Figure 6 yes Figure 5 Enlarged view of section III in the image; Figure 7 This is a schematic diagram of the anti-electric shock wall structure 20 provided by this utility model; Figure 8This is a structural schematic diagram of the display panel back cover 22 provided by this utility model; Figure 9 yes Figure 8 A magnified view of section IV in the image.

[0053] like Figures 3 to 9 As shown, the electric water heater 100 includes a housing body 10 and end caps 11 disposed at both ends of the housing body 10. The housing body 10 and the end caps 11 form a first receiving cavity. An inner tank 40 is disposed inside the first receiving cavity, and the inner tank 40 is connected to an inlet pipe and an outlet pipe. A positioning hole 12 and a screw hole are provided on the front side of the housing body 10 for installing an anti-electric shock wall structure 20. The anti-electric shock wall structure 20 includes an anti-electric shock wall cover 21 and a display panel rear shell 22 installed on the rear side of the anti-electric shock wall cover 21. The display panel rear shell 22 and the anti-electric shock wall cover 21 form a second receiving cavity, and the display panel 30 of the electric water heater 100 is located in the second receiving cavity.

[0054] The outer shell body 10 can be a cylindrical structure, which can be understood as a hollow columnar structure with a cross-section perpendicular to the axis of the outer shell body 10. The cross-sectional shape can be any suitable shape such as a circle, ellipse, fan, polygon, or irregular shape.

[0055] The outer shell 10 can be processed in various ways. It can be made of plastic material through a one-time molding process. There are various types of one-time molding processes, such as injection molding and 3D printing. The outer shell 10 obtained by one-time molding has no gaps on its surface and has good mechanical properties. Compared with the welded shells in the prior art, since there are no welds, the surface transition can be smooth, the outer shell 10 is not easy to crack, and it has a better appearance.

[0056] The following is a reference to the appendix. Figure 3 To be continued Figure 7 The specific structure of the anti-electric shock wall cover 21 is described.

[0057] like Figures 3 to 7 As shown, the anti-electric shock wall cover 21 includes a front side plate 211 and a bottom plate 212 connected in sequence. The front side plate 211 is configured with a control panel for mounting the electric water heater 100, and the control panel is communicatively connected to the display panel 30. The bottom plate 212 is provided with a first mounting hole 213 and a second mounting hole 214 for the water inlet pipe and water outlet pipe of the electric water heater 100 to pass through. On the back side of the front side plate 211, away from the edge of the bottom plate 212, a plurality of straight-insertion positioning posts 215 are provided at intervals along the length direction. When installing the anti-electric shock wall cover 21, the straight-insertion positioning posts 215 are inserted directly into the positioning holes 12 provided on the outer shell body 10 of the electric water heater 100 along their extension direction.

[0058] In the above scheme, since the multiple straight-insertion positioning posts 215 on the anti-electric shock wall cover 21 can be directly inserted into the multiple positioning holes 12 of the outer shell body 10, the opening size of the positioning hole 12 does not need to be larger than the size of the straight-insertion positioning post 215; their external dimensions only need to be equivalent. Therefore, referring to... Figure 6 As shown, when the straight-insertion positioning post 215 is installed in the positioning hole 12, the outer wall of the straight-insertion positioning post 215 abuts against the positioning hole 12, thereby achieving the purpose of preventing material overflow without the need to set up a baffle plate or baffle membrane.

[0059] It should be noted that the above-mentioned direct-insertion positioning post 215 can only be used for the initial positioning of the anti-electric wall cover 21 on the outer shell body 10. After the direct-insertion positioning post 215 is installed in the positioning hole 12, it is also necessary to fasten the anti-electric wall cover 21 and the outer shell body 10 to achieve the fixation of the two.

[0060] Specifically, such as Figure 6 As shown, screw posts 216 are respectively provided at the four corners of the base plate 212 of the anti-electric shock wall cover 21, and correspondingly, four screw holes are provided on the outer shell body 10. The screws are threadedly connected to the screw posts 216 and the outer shell body 10, thus firmly fixing the anti-electric shock wall cover 21. It is understood that the design of the screw posts 216 allows the screws to be embedded within them, preventing them from protruding from the anti-electric shock wall cover 21, thereby improving the overall aesthetics of the water heater. It should be noted that, while ensuring the anti-electric shock wall cover 21 is securely fixed to the outer shell body 10, the number of screw posts 216 and screw holes can be adjusted accordingly, and is not limited to the numbers listed in this embodiment.

[0061] In some embodiments, a plurality of baffle ribs 217 are provided on the back side of the front side plate 211 away from the edge of the bottom plate 212. Each baffle rib 217 corresponds one-to-one with a plurality of straight-insertion positioning posts 215, and each baffle rib 217 is circumferentially arranged around the outside of the straight-insertion positioning post 215. (Refer to...) Figure 6 As shown, after the straight-insertion positioning post 215 is installed in place with the positioning hole 12, the end of the baffle rib 217 abuts against the outer wall of the outer shell body 10 of the electric water heater 100 and is located around the positioning hole 12.

[0062] Specifically, errors inevitably occur during the processing of the two components. Therefore, after the direct-insertion positioning post 215 is installed in the positioning hole 12, small gaps may appear between them due to processing errors. To prevent the foaming material from leaking out of these small gaps, a baffle rib 217 is provided on the back of the front side plate 211, which surrounds the outside of the direct-insertion positioning post 215 in a circumferential direction. After the direct-insertion positioning post 215 and the positioning hole 12 are installed in place, the end of the baffle rib 217 can abut against the outer wall of the outer shell body 10 of the electric water heater 100 and is located outside the positioning hole 12. In this way, even if the foaming material leaks out from these small gaps, it can be blocked by the baffle rib 217 and will not overflow into the second receiving cavity, affecting the display of the display panel 30.

[0063] Optionally, a positioning plate 218 for positioning the rear shell 22 of the display panel is also provided on the back side of the front side plate 211 away from the edge of the bottom plate 212. The positioning plate 218 extends along the length of the front side plate 211 and is approximately the same length as the rear shell 22 of the display panel. The end of the baffle rib 217 that does not abut against the outer wall of the outer shell body 10 of the electric water heater 100 can extend to the front side plate 211 and the positioning plate 218. In other words, the baffle rib 217 includes three side walls connected in sequence. The three side walls surround the outside of the straight-insertion positioning post 215. One end of the three side walls is used to abut against the outer wall of the outer shell body 10 of the electric water heater 100, and the other end is connected to the front side plate 211 and the positioning plate 218 to increase the strength of the baffle rib 217.

[0064] Optionally, the straight-insertion positioning post 215 and the baffle 217 are integrally formed with the front side plate 211.

[0065] In some embodiments, the insertion end of the straight-insertion positioning post 215 is provided with a tapered chamfered relief portion, which facilitates the smooth insertion of the straight-insertion positioning post 215 into the positioning hole 12 when installing the anti-electric wall cover 21, thereby improving installation efficiency.

[0066] In some embodiments, the included angle between the front side plate 211 and the bottom plate 212 is approximately 90°. The straight-insertion positioning post 215 is a square or circular columnar structure, and the axial direction of the straight-insertion positioning post 215 has a preset angle with the width direction of the front side plate 211, which is less than 90°. Thus, when the straight-insertion positioning post 215 is installed in the positioning hole 12, the force between the straight-insertion positioning post 215 and the outer shell body 10 can overcome the gravity of the anti-electric shock wall cover 21, achieving the purpose of initial positioning. It should be noted that the axis of the straight-insertion positioning post 215 defined in this utility model is a straight line, and it does not have a bent portion. It should also be noted that the straight-insertion positioning post 215 can also be other shapes that match the shape of the positioning hole 12.

[0067] In some implementations, the direct-insertion positioning post 215 can be made into a hollow structure, provided that the support strength of the direct-insertion positioning post 215 can be ensured. This helps to reduce the weight of the electric water heater 100.

[0068] The following is a reference to the appendix. Figure 7 To be continued Figure 9 The specific structure of the display panel back cover 22 is described.

[0069] like Figures 7 to 9 As shown, the rear shell 22 of the display panel is installed on the back of the front side plate 211, forming a receiving cavity with the front side plate 211. The receiving cavity is configured to house the display panel 30 of the electric water heater 100. The display panel 30 is provided with a plurality of terminal plugs 31. The rear shell 22 of the display panel is provided with a main cable outlet 221, which is configured to allow signal lines connected to at least one of the plurality of terminal plugs 31 to pass through, thus preventing flying insects from entering due to the unused cable outlet being exposed.

[0070] Optionally, one side of the display panel rear shell 22 is snapped into the bottom plate 212 of the anti-electric shock wall cover 21, and the other side of the display panel rear shell 22 is connected to the front plate 211 of the anti-electric shock wall cover 21 by screws. This snap-fit ​​connection method occupies less space, increases the distance between the display panel rear shell 22 and the outer casing 10, and provides a certain amount of allowance for deformation of the outer casing 10 during the foaming process. This avoids interference between the outer casing 10 and the display panel rear shell 22, ensures the installation stability of the display panel rear shell 22, prevents the anti-electric shock wall cover 21 from being pushed up, and does not affect the aesthetics. At the same time, since the display panel rear shell 22 is not subjected to force, it ensures the safety of the control components and increases the safety of the electric water heater 100.

[0071] Specifically, a first latching protrusion is provided on the bottom side of the display panel rear shell 22, and a second latching protrusion is provided on the inner side of the bottom plate 212 of the anti-electric shock wall cover 21. The second latching protrusion has a latching groove, and the first latching protrusion is engaged in the latching groove. A mounting hole is provided on the upper side of the display panel rear shell 22, and a corresponding mounting hole is also provided on the front plate 211 of the anti-electric shock wall cover 21. The two mounting holes are connected by screws.

[0072] Furthermore, a protrusion 223 is provided on the side wall of the display panel rear shell 22. The protrusion 223 is configured to be opposite to the plurality of terminal plugs 31, and the main cable outlet 221 is provided on the protrusion 223. This allows the edge of the display panel 30 to completely abut against the side wall of the display panel rear shell 22, ensuring that the display panel 30 can be firmly installed on the display panel rear shell 22. In addition, as mentioned above, the bottom side of the display panel rear shell 22 is engaged with the bottom plate 212 of the anti-electric wall cover 21 by a snap-fit. That is, there is a clearance space between the bottom side of the display panel rear shell 22 and the bottom plate 212 of the anti-electric wall cover 21 due to the snap-fit. Therefore, the aforementioned protrusion 223 on the side wall of the display panel rear shell 22 is located within the clearance space, which does not affect the fixed connection between the display panel rear shell 22 and the anti-electric wall cover 21.

[0073] In some embodiments, a plurality of raised ribs 224 are provided on the bottom wall of the display panel rear shell 22 at positions corresponding to the protrusions 223 to form a plurality of spaced lead holes 222. The positions of the plurality of lead holes 222 are configured to correspond one-to-one with the positions of the plurality of terminal plugs 31. The lead holes 222 can provide mechanical support for the signal lines connected to the terminal plugs 31, preventing poor contact between the signal lines and the terminal plugs 31 due to pulling.

[0074] Furthermore, the protrusion 223 is integrally formed with the back shell 22 of the display panel, which improves the strength of the protrusion 223 and ensures its supporting function for the signal line.

[0075] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
