[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] In the description of this invention, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., 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 invention 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 invention.

[0037] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0038] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" 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; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0039] like Figures 1 to 6As shown, the present invention provides a water heater having a shell assembly and an inner tank. The shell assembly includes a bottom shell 1 and a front shell 2. The inner tank is disposed inside the bottom shell 1. The bottom shell 1 is also provided with a power board, which can be connected to an external power source via a power cord. The front shell 2 is provided with a display module 6. The bottom shell 1 is provided with a first hook part 3, which is provided with a first conductive structure and is connected to the power board. The front shell 2 is provided with a second hook part 4, which is provided with a second conductive structure and is electrically connected to the display module 6. The first hook part 3 can hook onto the second hook part 4 to fix the front shell 2 to the front of the bottom shell 1 and to electrically connect the first conductive structure and the second conductive structure.

[0040] The aforementioned housing assembly adopts a modular design of bottom shell 1 and front shell 2. The two are connected by hooking the first hook part 3 and the second hook part 4 to achieve fixed connection and electrical connection. On the one hand, when carrying out common appearance iterations, the manufacturer only needs to redesign and replace the front shell 2 without redesigning and replacing the bottom shell 1, which can realize the universality of the bottom shell 1, shorten the iteration development cycle, and reduce development costs. On the other hand, it also supports users to replace different styles of front shell 2, expanding users' personalized needs for appearance.

[0041] Optionally, multiple sets of the first hook part 3 and the second hook part 4 can be provided to improve installation stability. Optionally, the display module 6 can be connected to the power board by providing communication lines on the first hook part 3 and the second hook part 4; a wireless communication module can also be provided on the display module 6 to achieve communication connection with the power board.

[0042] It is understandable that the aforementioned housing assembly can also be used on other devices that require replacement of the faceplate 2.

[0043] In addition, the first hook part 3 can be hooked onto the second hook part 4 to realize the electrical connection between the power board and the display module 6, which can also reduce the difficulty for users to replace the faceplate 2 themselves.

[0044] For example, the first hook portion 3 can be a hook, that is, the hook is set on the bottom shell 1, and the second hook portion 4 can be a hanging groove, that is, the hanging groove is set on the front shell 2, so that the hook can be hooked on the hanging groove for stability. In this case, at least a part of the material of the hook can be made of conductive material to form a first conductive structure. The conductive part of the hook can be connected to the power board by a wire, and at least a part of the groove wall is made of conductive material to form a second conductive structure. The conductive groove wall of the groove can be connected to the display module 6 by a wire, so that the hook and the groove are in direct contact to form a conductive path. Of course, the first hook portion 3 can also be set as a hanging groove, that is, the hanging groove is set on the bottom shell 1, and the second hook portion 4 can be a hook, that is, the hook is set on the front shell 2, and at least a part of the first conductive structure and at least a part of the second conductive structure are also made of the above-mentioned conductive material.

[0045] In some alternative embodiments, the first hook portion 3 includes an insulating mounting buckle. In this case, a first conductive element 7 is provided inside the insulating mounting buckle. One end of the first conductive element 7 is connected to the power board, and the other end of the first conductive element 7 extends out of the insulating mounting buckle to form a first conductive structure. The second hook portion 4 includes an insulating hook. In this case, a second conductive element 8 is provided inside the insulating hook. One end of the second conductive element 8 is connected to the display module 6, and the other end of the second conductive element 8 extends out of the insulating hook to form a second conductive structure. That is, when the first hook portion 3 and the second hook portion 4 are hooked together, the insulating hook and the insulating mounting buckle themselves are not conductive, but conduct electricity through the contact between the first conductive element 7 and the second conductive element 8.

[0046] It is understandable that the first hook part 3 may include an insulating hook, and the second hook part 4 may include an insulating mounting buckle; details will not be elaborated further.

[0047] In some embodiments, to further improve stability, the first hook portion 3 and the second hook portion 4 are magnetically connected. That is, the first hook portion 3 has a first magnetic attraction portion, and the second hook portion 4 has a second magnetic attraction portion. When the first hook portion 3 and the second hook portion 4 are hooked together, the first magnetic attraction portion and the second magnetic attraction portion are magnetically connected. Specifically, when the first hook portion 3 is a hook, the first magnetic attraction portion is provided at the end of the first hook portion 3 away from the bottom shell 1; when the second hook portion 4 is a hanging groove, the groove wall of the hanging groove is provided with a second magnetic attraction portion, and vice versa. Further details will not be elaborated further.

[0048] For example, when the first hook portion 3 is a hook and the second hook portion 4 is a hanging groove, at least a portion of the first hook is made of a magnetic material, and at least a portion of the groove wall is made of a magnetic material, so that the two can be magnetically attracted upon contact. In this case, the first conductive part can be disposed on the first magnetic part, and the second conductive part can be disposed on the second magnetic part, so that the contact between the first conductive part and the second conductive part can be stabilized under the action of magnetic attraction.

[0049] In some alternative embodiments, the first hook portion 3 includes an insulating mounting buckle, and the second hook portion 4 includes an insulating hook. When the first conductive member 7 and the second conductive member 8 are provided, the portion of the first conductive member 7 extending out of the first hook portion 3 and the portion of the second conductive member 8 extending out of the second hook portion 4 are both made of magnetic material. This allows the first conductive member 7 and the second conductive member 8 to conduct electricity while also being magnetically attracted. Since the first conductive member 7 extends out of the first hook portion 3 and the second conductive member 8 extends out of the second hook portion 4, magnetic attraction and electrical connection are facilitated. Alternatively, the insulating mounting buckle and the insulating hook may also be made of magnetic material.

[0050] To better illustrate the overall structure, the following description focuses on the case where the first hook part 3 includes an insulating mounting buckle and the second hook part 4 includes an insulating hook:

[0051] In some embodiments, the faceplate 2 includes a support plate 21 and a decorative plate 22, wherein the decorative plate 22 covers a first side of the support plate 21, and the shape of the second side of the decorative plate 22 is adapted to the bottom shell 1 so that the support plate 21 fits against the outside of the bottom shell 1. Hooks are provided on the second side of the support plate 21. In some embodiments, multiple first hook portions 3 may be provided at intervals, and the first hook portions 3 and second hook portions 4 are provided in a one-to-one correspondence to ensure hook stability. Exemplarily, the decorative plate 22 and the support plate 21 may be connected by means of adhesion, but not limited to adhesive bonding, and the decorative plate 22 may be, but not limited to, an acrylic sheet. The support plate 21 provides support for the decorative plate 22. In the current embodiment, the thickness of the decorative plate 22 is less than the thickness of the support plate 21, thereby making the installation of the decorative plate 22 more stable; exemplaryly, the thickness of the decorative plate 22 is 1mm-3mm; and the thickness of the support plate 21 is 3mm-8mm.

[0052] Specifically, the insulating hook is inverted L-shaped, with its first end fixed to the support plate 21 and its second end facing downwards. The insulating mounting buckle is located on the side of the bottom shell 1 facing the front shell 2. The insulating mounting buckle is groove-shaped with a slot 31, so that the slot 31 faces the insulating hook, allowing the second end of the insulating hook to extend into the buckle for fixation. To ensure the insulating hook's stability, the insulating mounting buckle has a lower bottom wall 32 in the vertical direction of the bottom shell 1. The lower bottom wall 32 is located below the slot 31, so that when the insulating hook is hooked into the buckle, the second end of the buckle abuts against the lower bottom wall 32, and the end face of the slot 31 supports the insulating hook, maintaining stability. The inner wall of the buckle also prevents the second end of the insulating hook from moving horizontally, forming a horizontal limit and preventing the insulating hook from detaching from the buckle horizontally.

[0053] In order to facilitate the smooth insertion of the insulating hook into the insulating mounting buckle, the height of the inner cavity of the insulating mounting buckle is greater than the height of the insulating hook in the vertical direction along the bottom shell 1; in addition, the second end of the insulating hook facing the support plate 21 has an inclined guide surface that gradually approaches the support plate 21 from bottom to top, thereby facilitating the insertion of the insulating hook into the insulating mounting buckle.

[0054] In the current embodiment, a wiring groove is provided on the first side of the support plate 21. The second conductive member 8 is disposed in the wiring groove and protrudes from the end of the insulating hook away from the support plate 21. The first conductive member 7 is disposed on the bottom shell 1 and protrudes from the lower bottom wall 32 of the insulating mounting buckle. Thus, when the insulating hook is hooked onto the insulating mounting buckle, the first conductive member 7 and the second conductive member 8 come into contact to achieve electrical connection. In the current embodiment, the first conductive member 7 is disposed at the lower bottom wall 32 of the insulating mounting buckle, and the second conductive member 8 is disposed on the end face of the second end of the insulating hook. This allows the first conductive member 7 and the second conductive member 8 to make a tighter contact under the action of gravity, further improving stability.

[0055] For example, two second conductive elements 8 can be provided. One second conductive element 8 connects to the display module 6 to achieve circuit conduction, and the other second conductive element 8 connects to the display module 6 to achieve control signal conduction. To reduce interference, the distance between the two second conductive elements 8 is 5.0mm ± 0.1mm. If the distance is too small, interference is likely to occur; if the distance is too large, the overall size of the insulating hook will increase, thereby increasing the cost. It is understood that the number of first conductive elements 7 corresponds one-to-one with the number of second conductive elements 8.

[0056] In some alternative embodiments, signal conduction can also be achieved wirelessly, so only one second conducting element 8 needs to be set to achieve circuit conduction, which will not be described in detail here.

[0057] Specifically, the height of the base shell 1 in the vertical direction is greater than its width in the front-to-back direction. The top and bottom ends of the base shell 1 have outwardly convex arc-shaped structures. The vertical direction of the base shell 1 is based on its normal installation onto the mounting wall (that is, the vertical direction is as follows). Figure 4 The X direction in the diagram refers to the front-back direction, which is based on the bottom shell 1 being installed on the wall. The side closer to the wall is the back, and the side farther from the wall is the front (that is, the front-back direction is as follows). Figure 4 (In the Y direction), the front shell 2 is located on the front side of the bottom shell 1, with its upper end extending to the upper side of the bottom shell 1 and its lower end extending to the lower side of the bottom shell 1, thus improving its aesthetics. The display module 6 is located below the horizontal axis of the bottom shell 1, facilitating operator control. In some alternative embodiments, the bottom shell 1 can also be cylindrical.

[0058] In the current embodiment, the angle formed by the line connecting the center of the display module 6 and the center of the bottom shell and the horizontal axis of the bottom shell 1 is α, where α is 45°-60°. This allows the user's hand to touch the display module 6 at an angle, thus reducing the possibility of the bottom shell 2 detaching.

[0059] In some embodiments, the lower end of the support plate 21 protrudes upwards towards the bottom shell 1 to form a boss 24. The boss 24 fits against the lower side of the bottom shell 1, and the display module 6 is mounted on the boss 24, thereby ensuring that the support plate 21 protrudes towards the front shell 2, ensuring aesthetics. Specifically, the display module 6 can be embedded in the boss 24, and the support plate 21 is provided with a cutout for observing the display module 6. It is understood that the decorative plate 22 is provided with a cutout for placing the display module 6, or the decorative plate 22 can be made of a transparent material.

[0060] In some embodiments, a water pipe connector 5 is also provided at the bottom of the bottom shell 1, and a relief groove 23 is provided on the side of the boss 24 near the lower end of the front shell 2. The relief groove 23 is used to avoid the water pipe connector 5, and the boss 24 can make the lower end of the front shell 2 deviate away from the bottom shell 1, so as to better cover the water pipe connector 5 and make the whole more beautiful.

[0061] Furthermore, to further reduce the wobbling between the bottom shell 1 and the top shell 2, the support plate 21 and the bottom shell 1 are also magnetically connected. For example, several magnetic elements are provided on the support plate 21 and / or the bottom shell 1, so that the support plate 21 and the bottom shell 1 are attracted together by the magnetic elements, further improving the stability of the bottom shell 1 and the top shell 2. For example, several magnets can be provided on the support plate 21, and the bottom shell 1 can be made of metal, so that the two are attracted and fixed; or magnets can be provided on both the support plate 21 and the bottom shell 1, so that the two are attracted and fixed; or the support plate 21 can be made of iron shell material, and the bottom shell 1 can be provided with magnets alone.

[0062] 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.

[0063] The specific embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
