[0046] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0047] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional 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.

[0048] In the description of this utility model, "several" means one or more, "multiple" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0049] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0050] In the description of this utility model, the terms "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of this utility model. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0051] In a typical layout where the installation platform is located at the rear of the enclosure and the control box is fixed in the center of the platform, the wiring structure is integrated into the front panel of the control box. When users need to connect external power cables or test internal wiring, the forward-extending wire harness completely covers the terminal block area. Operators must frequently adjust the bending angle of the wire harness or use auxiliary tools to pry it open to observe the contact status, which significantly increases the complexity of the wiring process.

[0052] This application provides a water heater, such as Figure 1 As shown, in some embodiments, the water heater 1000 includes an installation platform 100, an electrical control box 200, and a terminal block 300.

[0053] like Figures 1 to 3As shown, the installation platform 100 is the basic support structure for supporting the electrical control box 200 and the terminal block 300. The installation platform 100 can be part of the housing 500 of the water heater 1000, or it can be an independent plate-like structure located inside the unit head. This application does not limit this. The installation platform 100 provides a stable installation foundation for the electrical control box 200 and the terminal block 300, realizing the installation and fixation of the electrical control box 200 and the terminal block 300.

[0054] The electrical control box 200 integrates a circuit control unit, which can be fixedly connected to the mounting platform 100 by bolts or clips. Its function is to centrally arrange electrical components and form protection to ensure the reliability of the circuit connection.

[0055] The terminal block 300 is a modular component for cable interfaces, and may include a main body 310 and a wiring structure 320. The wiring structure 320 can be various types of terminal blocks. The wiring structure 320 is located on one side of the main body 310. The terminal block 300 has two states: a first state and a second state. In the first state, the terminal block 300, such as... Figure 2 As shown, the main body 310 is parallel to the mounting platform 100, meaning the main body 310 is horizontally positioned. The wiring structure 320 is located at the top of the main body 310, ensuring the stability of the terminal block 300. In the second state, the terminal block 300... Figure 3 As shown, the main body 310 is inclined or vertically arranged, that is, the main body 310 forms a first angle greater than 0° with the mounting platform, so that the wiring structure 320 is oriented towards the positive side of the first direction. It should be noted that the main body 310 and the wiring structure 320 are relatively fixed, and the orientation of the wiring structure 320 is rotated by moving the main body 310; the first direction is... Figure 1 The front-to-back direction, specifically the positive direction from the electrical control box 200 to the front of the water heater 1000, defines the reference direction for the equipment's operating position and spatial layout. This direction can be determined based on the location of the equipment panel or maintenance opening. Its function is to orient the wiring structure 320 in the second state so that it is easily observed and accessed by the operator, improving the convenience of wiring connections and maintenance. For example, when the water heater 1000 is installed inside a cabinet, the cabinet door faces the front of the water heater 1000, and opening the cabinet door creates an operating opening. In the second state, the wiring structure 320 is positioned facing the operating opening, allowing operators to directly inspect and maintain the wiring structure 320 through the operating opening.

[0056] By switching between the first and second states of the terminal block 300, the spatial layout of the wiring structure 320 relative to the control box 200 and its operating position is changed. In the second state, the main body 310 of the terminal block 300 is tilted or vertically set, so that the wiring structure 320, which is traditionally located at the top, is converted into a side-exposed state, effectively avoiding the obstruction of the wiring of the control box 200 by external cables, thereby solving the problems of poor operation visibility and difficult maintenance.

[0057] In this embodiment, at least one of the mounting platform 100 and the electrical control box 200 is provided with a first connecting part 120, and the terminal block 300 is connected to the first connecting part 120. That is, in this application, the terminal block 300 can be connected to the mounting platform 100 or the electrical control box 200, or it can have two connection points along the front-back direction to connect to the mounting platform 100 and the electrical control box 200 respectively. The first connecting part 120 can be located on the mounting platform 100 near the electrical control box 200, or it can be located on the front edge of the mounting platform 100; the first connecting part 120 can also be integrated into the outer wall of the electrical control box 200. This embodiment does not limit this.

[0058] In the first example of the above embodiments, the main body 310 is detachably connected to the first connecting part 120, and the main body 310 is configured to separate from the first connecting part 120 to move from the first state to the second state.

[0059] The first connecting part 120 can be a protruding structure or a groove structure on the mounting platform 100. The main body 310 and the first connecting part 120 can be detachably connected, for example, by means of a snap-fit, bolt, or magnetic connection. When it is necessary to switch the terminal block 300 from the first state to the second state, the main body 310 can be detached from the first connecting part 120, and then the main body 310 can be moved to the desired position to form an inclined state.

[0060] In the second example of the above embodiment, the main body 310 is rotatably connected to the first connecting part 120, and the main body 310 rotates to switch between the first state and the second state. The main body 310 and the first connecting part 120 are rotatably connected, for example, through a hinge or bearing structure. In the second example, the main body 310 can be directly rotated to rotate from a horizontal state to an inclined state or a vertical state, thereby realizing the switching between the first state and the second state.

[0061] The connection method between the first connecting part 120 and the main body 310 is selected according to the application scenario. When complete disassembly is required, the snap-fit ​​structure allows for quick separation; when frequent adjustments are required, the use of a pivot structure can reduce the risk of losing parts.

[0062] In some embodiments, a first support structure 110 can be provided on the mounting platform 100, and a second support structure 260 can be provided on the mounting platform 100 or the electrical control box 200. The first support structure 110 and the second support structure 260 are spaced apart in the front-to-back direction. When the terminal block 300 is in the second state, the first support structure 110 and the second support structure 260 jointly support the main body 310. There is a height difference between the support positions of the first support structure 110 and the main body 310 and the support positions of the second support structure 260 and the main body 310, so that the main body 310 is tilted. The first support structure 110 and the second support structure 260 form two support points. The dual-point support can disperse the force on the tilted main body 310 and prevent the main body 310 from sliding during maintenance operations. Furthermore, the staggered support points force the main body 310 to form a stable tilt angle, enhancing the reliability of the support, improving the stability of the wiring structure 320 and the safety of maintenance operations, especially maintaining stability when subjected to external cable pulling.

[0063] The following description uses the example where both the electrical control box 200 and the terminal block 300 are connected to the mounting platform 100, and a first support structure 110 is provided on the mounting platform 100, with the top surface of the electrical control box 200 serving as the second support structure 260.

[0064] like Figures 1 to 3 As shown, the water heater 1000 includes a mounting platform 100, an electrical control box 200, and a terminal block 300. The mounting platform 100 is made of sheet metal and has a flat top surface. The electrical control box 200 is fixed to the mounting platform 100 by bolts. The terminal block 300 includes a main body 310 and a wiring structure 320. The main body 310 is injection molded from insulating plastic material and is in the shape of a rectangular plate; the main body 310 can also be formed by bending sheet metal. An insulating structure is provided between the wiring structure 320 and the main body 310. The wiring structure 320 is located on one side of the main body 310 and includes multiple terminals for connecting the internal wiring of the electrical control box 200 to external cables.

[0065] The terminal block 300 has two working states. In the first state, the main body 310 is placed horizontally on the mounting platform 100, and the wiring structure 320 is located on top of the main body 310. The main body 310 can be temporarily fixed to the mounting platform 100 by means of clips or magnetic adsorption to ensure stability during daily use.

[0066] When wiring is required, the operator can switch the terminal block 300 to the second state. The specific operation is as follows: First, release the fixing of the main body 310 to the mounting platform 100. Then, move the main body 310 and rotate it a certain angle during the movement, so that the main body 310 forms an angle greater than 0° with the horizontal plane. At this time, the wiring structure 320 is located on the front side of the main body 310.

[0067] In the second state, the first support structure 110 on the mounting platform 100 supports the front end of the main body 310, and the top of the electrical control box 200 supports the rear end of the main body 310, keeping the main body 310 tilted. Operators can easily perform wiring or maintenance operations in this state. After the operation is completed, the main body 310 is rotated back to a horizontal position, restoring the first state.

[0068] Through the above solution, this application achieves spatial orientation adjustment of the wiring structure 320, effectively solving the problem of external cables obstructing the view during wiring operations in traditional layouts. In the second state, the wiring structure 320 is laterally exposed, eliminating the physical obstruction of the operation view by the front wiring harness and improving the visibility of wiring and maintenance operations. Operators can directly observe the terminals and connection status without frequently adjusting the wiring harness position or using auxiliary tools. This design significantly improves the accuracy and efficiency of wiring operations and reduces the risk of misconnection. Simultaneously, the two-state design of the terminal block 300 balances stability in daily use and convenience during maintenance, meeting the needs of different working scenarios.

[0069] In some embodiments, such as Figure 1 As shown, the installation platform 100 adopts an independent plate structure, and the installation platform 100 is connected to the tank 500 of the water heater 1000 by fasteners such as bolts and clips.

[0070] like Figures 1 to 4 As shown, the mounting platform 100 is provided with a first connecting part 120. In the first state, the first connecting part 120 can be connected to the terminal block 300 through the first fastener 710. This fastening method not only ensures the fixing strength of the terminal block 300 in the first state, but also provides a detachable mechanical basis for switching to the second state, ensuring the reliability of the connection structure in both states. The first fastener 710 can be a fastening element such as a bolt or screw.

[0071] The central axis of the first fastener 710 is parallel to the first direction, that is, the locking direction and the disassembly direction of the first fastener 710 are also along the front and back direction. This allows the terminal block 300 to be fixed and disassembled from the operating port to the mounting platform 100, unifying the disassembly and assembly direction of the first fastener 710 with the wiring and maintenance direction, and reducing the need for operating space inside the cabinet.

[0072] To prevent other structures from obstructing the first connecting portion 120 or causing interference to other structures, the first connecting portion 120 can be located at the front end of the mounting platform 100, and a mounting groove 130 extending in a third direction can be provided on the top surface of the first connecting portion 120. Figure 1In the left-right direction, part of the structure of the terminal block 300 can extend into 130. The part of the first connecting part 120 located on the front side of 130 can be provided with a mounting hole. The first fastener 710 can pass through the mounting hole and the part of the terminal block 300 extending into 130, thereby fixing the terminal block 300 to the mounting platform 100 and keeping the terminal block 300 in the first state.

[0073] Since the first connecting part 120 is located at the front end of the mounting platform 100, and the terminal block 300 is locked by providing a mounting groove 130 in the first connecting part 120, interference or obstruction of the wiring harness caused by setting a connecting structure on the top surface of the terminal block 300 can be avoided. Furthermore, the end of the first fastener 710 can naturally protrude from the front side of the first connecting part 120, making it easy to lock and remove from the operating port.

[0074] The mounting platform 100 is also provided with a first limiting part 140, which can limit the movement of the terminal block 300 in a second direction. Figure 1 The left and right directions are defined. The first limiting part 140 can be a protrusion or a slot structure provided on the mounting platform 100. In the first state, the terminal block 300 is placed on the top of the mounting platform 100 and the left and right directions are defined, so that the mounting hole is aligned with the connection position of the terminal block 300, which facilitates the locking operation of the first fastener 710.

[0075] Furthermore, by setting the first limiting part 140, the displacement of the terminal block 300 in the left and right directions can be suppressed, thereby forming a multi-directional constraint with the connection of the first fastener 710 and improving the stability of the terminal block 300 in the first state.

[0076] Specifically, the first limiting part 140 may adopt a limiting hole. In the first state, part of the structure of the terminal block 300 extends into the limiting hole, thereby limiting the left and right directions of the terminal block 300.

[0077] Furthermore, the limiting hole is tapered along the first direction. The tapering shape of the limiting hole can be achieved through an inverted conical hole or a beveled guide structure. The front end of the limiting hole is larger, facilitating the insertion of part of the terminal block 300. Then, the terminal block 300 is pushed backward. When the structure of the terminal block 300 inserted into the limiting hole moves to the rear end of the limiting hole, the left and right sidewalls of the limiting hole can limit the structure of the terminal block 300 inserted into the limiting hole. During the backward movement of the terminal block 300, the left and right sidewalls of the limiting hole can achieve automatic centering of the terminal block 300, reducing alignment errors caused by manual adjustment and facilitating the alignment of the mounting hole of the first connecting part 120 with the connecting structure of the terminal block 300.

[0078] The number of first limiting parts 140 can be two, and the two first limiting parts 140 are arranged at intervals in the left and right directions.

[0079] The mounting platform 100 also includes a first support structure 110, which can be a limiting protrusion 111 protruding from the mounting platform 100. In the first state, the limiting protrusion 111 is located at the bottom of the terminal block 300 and is covered by the terminal block 300; in the second state, the front edge of the terminal block 300 abuts against the rear side of the limiting protrusion 111. The protrusion height of the limiting protrusion 111 should not be too high. When the first support structure 110 uses a limiting protrusion 111, the height of the first support structure 110 is designed so that the first support structure 110 does not cover the wiring structure 320 in the front-back direction.

[0080] The first support structure 110 can also be a first limiting groove formed on the mounting platform 100. In the first state, the first limiting groove is blocked by the terminal block 300. In the second state, the front edge of the terminal block 300 abuts against the front sidewall of the first limiting groove. When the first support structure 110 adopts the first limiting groove, the front sidewall of the first limiting groove can be inclined, thereby limiting the front edge of the terminal block 300 in the front-back and vertical directions and preventing the front end of the terminal block 300 from tilting up.

[0081] like Figures 1 to 4 As shown, the installation platform 100 is provided with a limiting baffle 150 and an installation plate 160. The limiting baffle 150 is provided with a second limiting groove 151. Part of the structure of the electrical control box 200 extends into the second limiting groove 151 to achieve left and right direction limiting of the electrical control box 200. Part of the structure of the electrical control box 200 is connected to the installation plate 160 by fasteners such as screws and buckles.

[0082] There can be two mounting plates 160, which are spaced apart in the left-right direction. The electrical control box 200 can move backward between the two mounting plates 160 until a part of the electrical control box 200 is engaged in the second limiting groove 151, and a part of the electrical control box 200 abuts against the front side of the mounting plate 160, thereby determining the installation position of the electrical control box 200.

[0083] In some embodiments, such as Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, the electrical control box 200 includes a box body 210 and electrical components disposed within the box body 210. The box body 210 has a downward-facing mounting cavity, and the electrical components are disposed within the mounting cavity. There is a gap between the end of the electrical components facing the opening and the mounting platform 100. Due to the orientation of the opening, any condensation formed on the inner wall of the box body 210 or on the electrical components will be naturally drawn towards the opening by gravity, preventing the accumulation of condensation and thus reducing the risk of accelerated aging or damage to the electrical components due to long-term immersion in water.

[0084] The top wall of the housing 210 can be used as a mounting base, allowing electrical components to be directly mounted from the opening onto the top wall of the housing 210, where control components are pre-installed. Specifically, each electrical component can be mounted onto a circuit board, which is then secured to the top wall of the housing 210 using screws or other fasteners. Wiring and soldering of the electrical components are performed externally to the housing 210. The housing 210 is mounted on the mounting platform 100 via an inverted design, eliminating the need for additional components to seal the opening.

[0085] like Figure 1 , Figure 4 and Figure 5 As shown, the electrical control box 200 is provided with a third connecting part 230 and a third limiting part 240. The third limiting part 240 is inserted into the second limiting groove 151 to limit the left and right movement of the electrical control box 200. The third connecting part 230 is aligned with the mounting plate 160 in the first direction for locking with screws or other fasteners. The position of the third connecting part 230 is adapted to the position of the connecting plate. When using mounting plates 160 spaced apart in the left and right direction, the third connecting part 230 can be provided on the left and right sides of the box body 210.

[0086] At least a portion of the third limiting part 240 is inclined relative to the mounting platform 100 in the front-back direction. The third limiting part 240 is inserted into the second limiting groove 151 to limit the electrical control box 200. The left and right edges and the top and bottom edges of the third limiting part 240 are limited by the inner wall of the limiting hole, thereby limiting the electrical control box 200 in the left-right and top-bottom directions. The inclined segment of the third limiting part 240 and the rear side of the electrical control box 200 cooperate with the limiting baffle 150 to limit the electrical control box 200 in the front-back direction.

[0087] In practical applications, the end of the third limiting part 240 away from the box body 210 can be tilted downwards. That is, when the box body 210 is placed on the mounting platform 100, the bottom edge of the box body 210 is not completely flush with the top surface of the mounting platform 100, but rather tilted upwards. As the control box 200 is moved backwards, the tilted portion of the third limiting part 240 can align with the second limiting groove 151 on the limiting baffle 150. As the control box 200 continues to move, the third limiting part 240 will gradually insert into the second limiting groove 151. Due to the tilted design, the rear side of the box body 210 will gradually descend as it moves until the tilted portion of the third limiting part 240 completely passes through the second limiting groove 151, and the bottom edge of the box body 210 will be completely flush with the top surface of the mounting platform 100.

[0088] Conversely, when disassembling the control box 200, the rear end of the control box 200 needs to be lifted until the inclined part of the third limiting part 240 is completely disengaged from the second limiting groove 151, and then the control box 200 is moved forward until it is removed.

[0089] It should be noted that the inclined section of the third limiting part 240 can completely pass through the second limiting groove 151 and abut against the limiting baffle 150 at the same position, or the control box 200 can continue to move backward until the rear end of the control box 200 abuts against the limiting baffle 150 after the inclined section of the third limiting part 240 completely passes through the second limiting groove 151; this application does not limit this.

[0090] The third limiting part 240 has rounded corners at both ends of its edge away from the housing 210. When the electrical control box 200 moves backward to mate with the mounting platform 100, the rounded corners of the third limiting part 240 will first contact the edge of the limiting baffle 150 or the second limiting groove 151. Due to the rounded corner design, it can more smoothly guide the electrical control box 200 to the correct installation position and absorb errors in the left and right directions.

[0091] In other embodiments, the third limiting part 240 may also be a portion bent near the box body 210, and the bending direction may also be upward. This application does not limit this.

[0092] like Figure 2 As shown, the front of the electrical control box 200 has a cable outlet 250. In the first state, the main body 310 of the terminal block 300 is located on the front of the electrical control box 200, and the wiring structure 320 is correspondingly arranged with the cable outlet 250 in the front-rear direction. The internal wires of the electrical control box 200 can directly pass through the cable outlet 250 in the first direction and connect to the wiring structure 320, avoiding wire crossing.

[0093] In some embodiments, such as Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, the terminal block 300 includes a main body 310 and a wiring structure 320. The main body 310 is provided with a second connecting part 311 and a second limiting part 312. In the first state, the second limiting part 312 cooperates with the first limiting part 140 to limit the terminal block 300 in the left and right directions, so that the first connecting part 120 and the second connecting part 311 are aligned, which facilitates the locking of the first fastener 710.

[0094] When the first support structure 110 adopts the first limiting groove, the main body 310 can naturally cover the first limiting groove in the first state, thereby blocking the first limiting groove. When the first support structure 110 adopts the limiting protrusion 111, the bottom of the main body 310 can be designed with a clearance space, so that in the first state, the limiting protrusion 111 of the main body 310 can be accommodated in the clearance space, thereby not interfering with the installation of the terminal block 300.

[0095] The main body 310 can be a plate-like structure with a certain thickness, thereby forming a clearance space by digging a groove at the bottom of the main body 310; the main body 310 can also be formed by bending a metal plate. Specifically, by bending the edges of the main body 310 to form a supporting fold, the flat plate in the middle of the main body 310 is suspended to form a clearance space; this embodiment does not limit the specific structure of the main body 310.

[0096] The second connecting part 311 can be exposed at the bottom edge of the main body 310, so that the second connecting part 311 can extend into the mounting groove 130 on the first connecting part 120. The second connecting part 311 can also be provided with mounting holes. When the second limiting part 312 cooperates with the first limiting part 140, the mounting holes on the first connecting part 120 and the mounting holes on the second connecting part 311 are aligned in the front-back direction.

[0097] The second limiting part 312 includes an inclined section and a straight section. When the terminal block 300 is in the first state, the inclined section passes through the limiting hole, and the straight section is located at the bottom of the mounting platform 100 and cooperates with the mounting platform 100 to limit the vertical displacement of the terminal block 300, thereby improving the stability of the terminal block 300 in the first state.

[0098] The portion where the main body 310 connects to the second limiting part 312 forms an inclined surface, thereby creating a transitional inclined surface between the top surface of the mounting platform 100 and the top surface of the terminal block 300, preventing sharp edges from damaging the cable.

[0099] A wire clip 330 can also be installed on the terminal block 300 to organize the externally led wires and keep the position of the end of the externally led wires connected to the wiring structure 320 stable.

[0100] This utility model also proposes an embodiment, such as... Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown, the difference between this embodiment and the above embodiment is that the water heater 1000 also includes a wiring cover 400, which is detachably connected to the wiring socket 300. The wiring cover 400 is used to cover the wiring structure 320 when the wiring socket 300 is in the first state, thereby protecting the wiring structure 320 and the wire harness connected to the wiring structure 320 and meeting safety requirements. The wiring cover 400 can also be separated from the wiring socket 300 when the wiring socket 300 is in the second state, thereby exposing the wiring structure 320 and the wire harness connected to the wiring structure 320 for easy maintenance.

[0101] The wiring cover 400 can be moved forward or diagonally upward to separate from the wiring socket 300, so that the wiring cover 400 can be removed from the front operation port to meet the installation needs of small spaces such as cabinets.

[0102] like Figure 7 and Figure 8 As shown, when the terminal cover 400 is included, the terminal block 300 and the terminal cover 400 have corresponding connection structures. Specifically, the terminal block 300 has a plug hole 313, and the terminal cover 400 has a insert 410. The insert 410 can be inserted into the plug hole 313 to limit the front-back and left-right directions of the terminal cover 400.

[0103] The insertion hole 313 can adopt a diamond-shaped structure, thereby allowing for a certain installation error and facilitating the insertion of the insert 410.

[0104] The wiring cover 400 is also provided with a support plate 420. The insert 410 can be connected to the edge of the support plate 420. The support plate 420 contacts the top surface of the terminal block 300 to form a support surface. The support plate 420 is connected to the terminal block 300 by fasteners such as screws, thereby improving the stability of the connection between the wiring cover 400 and the terminal block 300.

[0105] Understandably, such as Figure 1 As shown, the water heater 1000 typically includes a housing 500 and a cover 600. The cover 600 is detachably connected to the housing 500 and forms an installation space. At least the electrical control box 200 and the terminal block 300 are located within the installation space, serving to provide waterproofing and dustproofing.

[0106] In one embodiment, the cover 600 is configured to move along a first direction to detach from the housing 500. The cover 600 can also be removed from the front of the water heater 1000 without requiring additional operating space in multiple directions. This improves space utilization efficiency, allowing the water heater 1000 to flexibly adapt to the installation requirements of compact spaces such as cabinets.

[0107] It should be noted that the movement of the cover 600 along the first direction to detach from the box 500 in this application does not mean that the limiting and releasing of the limiting between the cover 600 and the box 500 is achieved by moving in the front-back direction. In practical applications, a first limiting member can be provided on the rear side of the box 500, and a second limiting member can be provided on the rear side of the cover 600. By moving the cover 600 backward, the first limiting member and the second limiting member engage to limit the vertical and horizontal directions; conversely, moving the cover 600 forward releases the engagement of the first and second limiting members. Alternatively, a first limiting member can be provided at the top of the housing 500, forming a downward-locking cavity with the cover 600. A second limiting member is provided on the inner wall of the cavity. The first and second limiting members are engaged or disengaged by rotating clockwise or counterclockwise. In this case, after disengaging the limiting member, the cover 600 needs to be moved upward so that its bottom edge is higher than the electrical control box 200, and then the cover 600 needs to be moved forward to completely detach it from the housing 500. Understandably, no operating space needs to be reserved on the left, right, and rear sides for the rotation operation.

[0108] The first and second limiting members mentioned above can be selected from the snap-fit ​​structure or the structure of the insert and the slot that are conventionally used in the art, which will not be described in detail in this application.

[0109] Based on the above embodiments, the water heater 1000 also includes a second fastener (not shown), which connects the cover 600 to the front side of the housing 500, and the central axis of the second fastener is arranged along the front and rear. Similar to the first fastener, all disassembly, assembly, and maintenance operations are concentrated on the same side of the water heater 1000. This consistent design not only simplifies the operation process but also further enhances the advantages of space utilization. The second fastener can be a bolt or screw or other fastening element.

[0110] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
