[0042] Reference Figure 1 and Figure 2 As shown, this embodiment provides an electric water heater, which includes a water storage tank 100, a submersible electric heating element 200, a first mounting plate 300, and a second mounting plate 400.

[0043] Specifically, the water storage tank 100 has a first end and a second end along its length, and the water storage tank 100 has a water storage cavity 110; the submersible electric heating tube 200 is located in the water storage cavity 110 and connected to the first end of the water storage tank 100; the first hanging plate 300 is disposed on the water storage tank 100 and is located near the first end of the water storage tank 100, and the two ends of the first hanging plate 300 are respectively provided with a first hanging hole 310 and a second hanging hole 320. In the extending direction of the first hanging plate 300, the first hanging hole 310 is located near the submersible electric heating tube 200; the second hanging plate 400 is disposed on the water storage tank 100 and is located near the second end of the water storage tank 100, and both ends of the second hanging plate 400 are provided with a third hanging hole 410; the sealing member 500 is detachably installed on the first hanging plate 300 to seal the first hanging hole 310.

[0044] For example, the first hanging plate 300 and the second hanging plate 400 can be parallel to each other or at an angle to each other; this embodiment does not impose any limitation.

[0045] It is understandable that the sealing component 500 can block the first hanging hole 310 and interfere with the hanging of the first hanging hole 310, that is, the first hanging hole 310 cannot be hooked by the hook, thus achieving the effect of preventing fooling.

[0046] When the electric water heater is installed vertically, the storage tank 100 can only be hung through the two third hanging holes 410; when the electric water heater is installed horizontally, the storage tank 100 can only be hung through the second hanging hole 320 and the corresponding third hanging hole 410 along the length of the storage tank 100. The sealing component 500 effectively prevents the electric water heater from being installed backwards, thus avoiding abnormal heating, low hot water volume in the storage chamber 110, and incomplete filling due to reverse installation.

[0047] In this embodiment, reference is made to Figure 2 As shown, the electric water heater also includes a control box 600, which is located at the first end of the water storage tank 100 or at the periphery of the water storage tank 100. The control box 600 is electrically connected to the submersible heating element 200, meaning the water heater can control the submersible heating element 200 to heat the water in the water storage chamber 110 via the control box 600. In this embodiment, based on the size, installation environment, and appearance of the water storage tank 100, installing the control box 600 at the end or periphery of the water storage tank 100 prevents positional interference during installation and ensures the aesthetics of the water heater.

[0048] In this embodiment, reference is made to Figures 1 to 3 As shown, the sealing component 500 is snapped into the first mounting plate 300, facilitating the installation and removal of the sealing component 500 from the first mounting plate 300. Of course, the sealing component 500 can also be installed on the first mounting plate 300 by bolts, adhesive bonding, or other methods; this embodiment does not limit this.

[0049] Specifically, the sealing component 500 includes a base plate 510 and a plurality of buckles 520 spaced circumferentially along the base plate 510. The base plate 510 is engaged with the first hanging hole 310 by at least two buckles 520. In this embodiment, the base plate 510 can effectively block the first hanging hole 310, thereby interfering with the hanging of the first hanging hole 310. In addition, the sealing component 500 can be engaged with first hanging holes 310 of different sizes and specifications by selecting the buckles 520, which has good applicability and avoids the situation of selecting the sealing component 500 for first hanging holes 310 of different sizes and specifications, thus facilitating management.

[0050] For example, the sealing element 500 can be made of plastic, which is easy to mold and manufacture and has good toughness. During installation, the buckle 520 is easily deformed by the pressure of the first hanging hole 310 so that the buckle 520 can pass through the first hanging hole 310. After passing through the first hanging hole 310, the buckle 520 can spring back and form a snap-fit ​​with the first hanging hole 310, which facilitates installation.

[0051] For example, the shape of the base plate 510 includes, but is not limited to, a rectangle or a circle.

[0052] In one feasible implementation, the base plate 510 is located on the side of the first hanging plate 300 near the water storage tank 100, which effectively prevents the base plate 510 from being knocked off the first hanging plate 300 by external objects.

[0053] In one feasible implementation, the height H of the inverted buckle 520 is greater than the thickness B of the inverted buckle 520, so that the inverted buckle 520 has better toughness and effectively prevents the sealing part 500 from breaking when it is disassembled from the first hanging plate 300.

[0054] In one feasible implementation, the height H of the inverted buckle 520 is less than the distance between the base plate 510 and the mounting wall to prevent the inverted buckle 520 from hitting the mounting wall and causing the first hanging plate 300 to lift up, that is, to prevent the electric water heater from being installed crookedly.

[0055] For example, the height H of the inverted clip 520 is in the range of 3mm-8mm, such as 4mm, 5mm or 6mm, so that the inverted clip 520 has good toughness and effectively prevents the inverted clip 520 from hitting the wall surface.

[0056] For example, the thickness B of the undercut 520 is less than or equal to 2.8 mm, such as 2.5 mm, 2 mm or 1.5 mm, so that the undercut 520 has good toughness.

[0057] In some embodiments, such as Figure 4 and Figure 5As shown, the inverted buckle 520 includes two first inverted buckles 521 arranged opposite each other along a first direction and two second inverted buckles 522 arranged opposite each other along a second direction. The first and second directions are perpendicular to each other, and the first direction is parallel to the extension direction of the first hanging plate 300. The base plate 510 is engaged with the first hanging hole 310 via the two first inverted buckles 521 or via the two second inverted buckles 522. It is understood that the first hanging hole 310 engaged with the first inverted buckle 521 and the first hanging hole 310 engaged with the second inverted buckle 522 have different dimensions. In this embodiment, the arrangement of the two first inverted buckles 521 and the two second inverted buckles 522 ensures that the inverted buckle 520 has good applicability, and the sealing member 500 has a simple structure, facilitating molding and manufacturing. Furthermore, the first direction is parallel to the extension direction of the first hanging plate 300, meaning the base plate 510 is engaged with the first hanging holes 310 of different sizes in the same orientation, facilitating positioning and assembly.

[0058] It is understandable that different water heater models have different mounting plates, and different mounting plates have different mounting holes. By setting the distance between the two first inverted clips 521 to be different from the distance between the two second inverted clips 522, the inverted clips 520 can be installed on different mounting holes, which can improve applicability.

[0059] For example, the shape of the first hanging hole 310 includes, but is not limited to, a rectangle or an ellipse.

[0060] In one feasible implementation, the distance L1 between the two first buckles 521 is greater than the distance L2 between the two second buckles 522, so that the two first buckles 521 can engage with the larger first hanging hole 310, and the two second buckles 522 can engage with the smaller first hanging hole 310. Figure 6 The size of the first hanging hole 310 in the middle is greater than Figure 7 The dimensions of the first hanging hole 310 in the middle.

[0061] For example, the distance L1 between the two first buckles 521 ranges from 15mm to 30mm, and the relationship between the distance L1 between the two first buckles 521 and the distance L2 between the two second buckles 522 is: 3mm < L1 - L2 < 8mm. For example, the distance L1 between the two first buckles 521 is 25mm, and the distance L2 between the two second buckles 522 is 20mm. While ensuring that the sealing component 500 has a compact structure, the two first buckles 521 are suitable for engaging with the first hanging hole 310 with a larger size, and the two second buckles 522 are suitable for engaging with the first hanging hole 310 with a smaller size.

[0062] In one feasible implementation, such as Figure 6As shown, the sealing component 500 is engaged with the first hanging hole 310 by two first buckles 521, and the two second buckles 522 cooperate with the first hanging hole 310 to limit the range of sway of the sealing component 500 relative to the first hanging plate 300 in the second direction, effectively preventing the sealing component 500 from detaching from the first hanging plate 300 during the transportation of the electric water heater.

[0063] In one feasible implementation, such as Figure 7 As shown, the sealing component 500 is engaged with the first hanging hole 310 by two second buckles 522. The two first buckles 521 cooperate with the first hanging hole 310 to limit the range of sway of the sealing component 500 relative to the first hanging plate 300 in the first direction, effectively preventing the sealing component 500 from detaching from the first hanging plate 300 during the transportation of the electric water heater.

[0064] In this embodiment, reference is made to Figure 6 and Figure 7 As shown, the sealing member 500 may be provided with an identifying arrow 511, the direction of which is the same as the extension direction of the first mounting plate 300. For example, when installing the sealing member 500, it is not necessary to distinguish the size of the first mounting hole 310; simply point the identifying arrow 511 toward or away from the second mounting hole 320, and then press the sealing member 500 toward the first mounting hole 310 to snap the sealing member 500 into the first mounting hole 310, facilitating installation.

[0065] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.

[0066] The specific embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
