[0046] 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.

[0047] The electrical control box of a water heater is typically used to implement functions such as temperature control, time management, mode selection, safety protection, information display, and interaction. In related technologies, the electrical control box is fixed inside the water heater's main unit from multiple directions using screws. During installation and disassembly, various components need to be locked or released at multiple connection points in a specific sequence and direction, limiting the operational path. Furthermore, sufficient operating space needs to be reserved in each direction, which cannot meet the installation requirements of small spaces such as cabinets.

[0048] To address the aforementioned problems, this application proposes an electronic control box assembly. In some embodiments, such as Figure 1 and Figure 2 As shown, the electrical control box assembly 100 includes a first box body 110 and a second box body 120. The first box body 110 is detachably connected to the mounting platform 130 and is configured to move along a first direction to separate from the mounting platform 130. The second box body 120 is detachably connected to at least one of the mounting platform 130 and the first box body 110. When the second box body is connected to the mounting platform, the second box body can move along the first direction to separate from the mounting platform. When the second box body is connected to the first box body, the second box body can move along the first direction to separate from the first box body. Alternatively, the second box body and the first box body can move together as a whole along the first direction to separate from the mounting platform. In practical applications, the first box 110 and the second box 120 are disassembled by moving along the first direction and installed by moving in the opposite direction. Since the first box 110 and the second box 120 are installed and disassembled in the same direction, the installation and disassembly operations can be performed on the same side of the water heater 1000, thus eliminating the need to reserve operating space in each direction, improving space utilization, and adapting to the installation needs of small spaces such as cabinets.

[0049] For example, when the water heater 1000 is located inside a cabinet, the direction facing the opening formed by the cabinet door can be designed as the first direction, so that the installation can be carried out using the passage connecting to the outside formed by the cabinet door.

[0050] Based on the above embodiments, such as Figure 1 and Figure 2 As shown, the first housing 110, the second housing 120, and the mounting platform 130 can be fixed together by a first fastener 140. The central axis of the first fastener 140 is set along a first direction. That is, the fixing and disassembly of the first fastener 140 are also carried out in the first direction and the reverse direction of the first direction, which is consistent with the installation and disassembly direction of the first housing 110 and the second housing 120. This avoids the need to reserve operating space in multiple directions, making the electrical control box assembly 100 more compact and suitable for installation environments with limited space.

[0051] The first fastener 140 can be a screw. In the first housing 110, the second housing 120 and the mounting platform 130, at the connection between two adjacent parts, the outer part is provided with a through hole and the inner part is provided with a threaded hole. The screw passes through the through hole and is threadedly connected to the threaded hole, thereby fixing the two adjacent parts. Of course, the fixing can be released by removing the screw.

[0052] In other embodiments, the first fastener 140 may also be a common detachable connection structure such as a snap-fit, and this application does not limit this.

[0053] In the first example of the above embodiments, the first box 110, the second box 120, and the mounting platform 130 are connected by the first fastener 140, which simplifies the fixing structure of the first box 110, the second box 120, and the mounting platform 130.

[0054] In the second example of the above embodiments, such as Figure 1 and Figure 2 As shown, the first housing 110 is connected to the mounting platform 130 via the first fastener 140, and the second housing 120 is connected to the first housing 110 via the first fastener 140. In this example, only the first fastener 140 connecting the first housing 110 and the mounting platform 130 can be disconnected, allowing the first housing 110 and the second housing 120 to be disassembled as a whole. Alternatively, only the first fastener 140 connecting the second housing 120 and the first housing 110 can be disconnected, allowing for independent disassembly of the second housing 120 and improving maintenance convenience. Furthermore, the connection between the second housing 120 and the first housing 110 via the first fastener 140 allows for better adjustment of their positional relationship, facilitating cable routing.

[0055] In the third example of the above embodiments, the first box 110 and the second box 120 are respectively connected to the mounting platform 130 through a first fastener 140. That is, both the first box 110 and the second box 120 are mounted on the mounting platform 130. The second box 120 may not be connected to the first box 110, which facilitates the wiring or connection between the first box 110 and the second box 120, and makes it easier to adjust the relative position of the second box 120 and the first box 110 on the mounting platform 130.

[0056] The first, second, and third examples described above can all be connected by first fasteners 140 on the left and right sides respectively, thereby improving connection stability and preventing the cable from becoming loose or making poor contact due to the movement of the first housing 110 and the second housing 120 during use.

[0057] Among them, such as Figure 3 As shown, the mounting platform 130 can be an independent component connected to the housing 200 of the water heater 1000, such as the mounting plate 130a connected to the top of the housing 200; the mounting platform 130 can also be a part of the structure of the housing 200 of the water heater 1000, such as the top plate of the housing 200; this application does not limit this.

[0058] The first housing 110 and the second housing 120 can each integrate different electrical components 150, thus forming functionally defined sub-housings. The first housing 110 and the second housing 120 can be electrically connected via pre-reserved interfaces, such as connectors or slots, when the second housing 120 and the first housing 110 are mounted on the mounting platform 130, thus forming a complete electrical control system. Alternatively, one of the first housing 110 and the second housing 120 can serve as the main load-bearing part for the electrical components 150, with a cable outlet 115 and a docking terminal 116 at one end along the first direction for connection to external circuits or sensors; the other can serve as a cover, shielding the cable outlet 115 and the docking terminal 116 for protection.

[0059] The following description uses the installation platform 130 as an independent installation plate 130a, the first box 110 as the main load-bearing structure, and the second box 120 as the box cover as an example.

[0060] like Figure 1 As shown, the first direction is the forward direction, and the opposite direction of the first direction is the backward direction.

[0061] In some embodiments, the mounting plate 130a may have a support structure, which may be spaced apart in the left-right or front-back direction and may be locked to the top surface of the housing 200 by screws. A portion of the mounting plate 130a is formed in the middle that is suspended relative to the top surface of the housing 200, and this portion serves as a mounting surface for supporting the first housing 110 and the second housing 120.

[0062] like Figure 1 and Figure 2 As shown, the mounting plate 130a may be provided with a first connecting part 131, a first limiting part 132, and a first snap-fit ​​part 133 for limiting and installing the first box 110 and the second box 120.

[0063] The first limiting part 132 is used to block the first box 110 during the backward movement of the first box 110, and cooperates with the partial structural limiting of the first box 110 to limit the vertical, horizontal and forward and backward directions of the first box 110, so that the position of the first box 110 can be determined before the first fastener 140 is locked.

[0064] The first connecting portion 131 is used to lock a portion of the structure of the first housing 110 with the first fastener 140. For ease of description, the portion of the first housing 110 that mates with the first limiting portion 132 is referred to as the second limiting portion 112, and the portion of the first housing 110 that mates with the first connecting portion 131 is referred to as the second connecting portion 111. When the first housing 110 moves backward until the second limiting portion 112 and the first limiting portion 132 are engaged, the second connecting portion 111 and the first connecting portion 131 are aligned along a first direction and can be exposed from the side or top of the second housing 120, thereby facilitating the locking of the first fastener 140.

[0065] Specifically, the first connecting part 131 can be a connecting piece that protrudes from the mounting surface. There are two first connecting parts 131, which are spaced apart in the left-right direction. The gap between the two first connecting parts 131 allows the first box body 110 to slide in the rearward or forward direction.

[0066] In other embodiments, the first connecting portion 131 may also be a plate-like structure with a slot at the bottom, through which the first housing 110 passes during installation and disassembly. That is, the first connecting portion 131 includes two vertical plates and a horizontal plate connected to the top of the two vertical plates. The bottom of the two vertical plates is connected to the mounting plate 130a, and the top horizontal plate and the two vertical plates can all form connection points. In other words, the first connecting portion 131 forms connection points on the left, right, and top sides of the first housing 110, thereby further enhancing the connection stability of the first housing 110. This application does not limit the specific shape of the first connecting portion.

[0067] Understandably, since the first housing 110 moves rearward to engage with the first limiting part 132, the second connecting part 111 is typically located in front of the first connecting part 131. Therefore, a threaded hole can be provided on the first connecting part 131 for threaded engagement with the first fastener 140. Alternatively, a through hole can be provided on the first connecting part 131, and a nut can be welded to the rear side of the first connecting part 131, aligning the threaded hole of the nut with the through hole for threaded engagement with the first fastener 140.

[0068] like Figure 1 , Figure 2 and Figure 4As shown, the first limiting part 132 includes a limiting baffle 1321 and a limiting hole 1322. The limiting baffle 1321 is connected to the mounting plate 130a. The limiting hole 1322 can be formed on the limiting baffle 1321 or at the connection between the limiting baffle 1321 and the mounting plate 130a. When the first box 110 moves backward, the second limiting part 112 can be inserted into the limiting hole 1322. The first box 110 continues to move backward until a part of the structure of the first box 110 is stopped by the limiting baffle 1321, so that the first box 110 moves into place and is limited.

[0069] In other embodiments, the first connecting part 131 may cooperate with the second connecting part 111, that is, the first box 110 may be moved backward until the second connecting part 111 abuts against the first connecting part 131, instead of the limiting baffle 1321 blocking the first box 110; this application does not limit this.

[0070] Specifically, the first limiting part 132 is offset from the first connecting part 131, and the first limiting part 132 is located on the rear side of the first connecting part 131. That is, the limiting baffle 1321 is located on the rear side of the first connecting part 131, and the limiting hole 1322 is located between the two first connecting parts 131. Thus, the limiting baffle 1321 can contact the rear side of the first box 110 to achieve limiting in the first direction. The second limiting part 112 is located on the rear side of the first box 110. When installing the first box 110, it is only necessary to pass the first box 110 between the two first connecting parts 131 and move it backward until the limiting baffle 1321 abuts against it; and when disassembling the first box 110, the first box 110 can be moved forward directly so that the first box 110 passes between the two first connecting parts 131.

[0071] In other embodiments, the number of first limiting portions 132 may also be two, with the two first limiting portions 132 aligned with the two first connecting portions 131 in the front-back direction, or the two first connecting portions 131 located between the two first limiting portions 132. In this case, the second limiting portion 112 protrudes from both sides of the first housing 110. When installing the first housing 110, the second limiting portion 112 is placed between the first limiting portion 132 and the first connecting portion 131, and then the first housing 110 is moved backward so that the second limiting portion 112 is inserted into the limiting hole 1322 and contacts the limiting baffle 1321 to achieve limiting engagement; and when disassembling the first housing 110, the first housing 110 needs to be lifted upward a certain distance to avoid interference between the second limiting portion 112 and the first connecting portion 131.

[0072] like Figure 1 , Figure 2 , Figure 4As shown, the first latching part 133 is located on the front side of the first connecting part 131. The first latching part 133 is used to latch and connect with a part of the structure of the second box 120, so that the position of the second box 120 can be determined before the first fastener 140 is locked on the second box 120, so that a part of the structure of the second box 120 can be aligned with the second connecting part 111 of the first box 110 in the first direction for the first fastener 140 to be locked.

[0073] For ease of description, the part of the second housing 120 that engages with the first latching part 133 is referred to as the second latching structure, and the part of the second housing 120 that engages with the second connecting part 111 is referred to as the third connecting part 122. The first latching part 133 may be a latch provided on the mounting plate 130a, and the second latching part 121 can pass through the latch so that the bottom surface of the second housing 120 is supported on the mounting plate 130a. At this time, the second housing 120 is in the first state. When the second housing 120 is moved backward, the edge structure of the latch can engage with the second latching part 121, thereby engaging and connecting with the second latching part 121. At this time, the second housing 120 is in the second state. In the second state, the position of the second housing 120 on the mounting plate 130a is determined, and the third connecting part 122 is aligned with the second connecting part 111 along the first direction for locking by the first fastener 140.

[0074] Since the mounting surfaces of the first housing 110 and the second housing 120 are suspended relative to the top of the housing 200, i.e., there is a gap between the mounting surfaces and the top of the housing 200, this gap can accommodate the portion of the second latching part 121 that extends into the latch. In other embodiments, a recessed structure may also be provided on the top of the housing 200 corresponding to the latch to accommodate the second latching part 121; this application does not limit this.

[0075] Conversely, when the second box 120 is in the second state, moving the second box 120 forward can disengage the edge of the latch from the second latch 121, thereby releasing the latch connection and returning the second box 120 to the first state; in the first state, the second box 120 can be moved upward to completely disengage the second latch 121 from the latch, and then the second box 120 can be moved forward to disassemble the second box 120.

[0076] Specifically, such as Figure 2 , Figure 4 and Figure 5As shown, the bayonet includes a first segment 1331, a transition segment 1332, and a second segment 1333 connected sequentially along a first direction. The length of the first segment 1331 is greater than the length of the second latching part 121, and the width of the first segment 1331 is greater than the width of the second latching part 121. The length is a dimension parallel to the first direction, and the width is a dimension perpendicular to the first direction. The first segment 1331 is designed to facilitate the insertion of the second latching part 121. The width of the transition segment 1332 gradually decreases towards the second segment 1333, i.e., the transition segment... 1332 can guide the movement of the second latching part 121, and make fine adjustments to the left and right positions of the second box 120 during the movement of the second box 120 to ensure that the second latching part 121 can accurately enter the second segment 1333; the width of the second segment 1333 matches the width of the second latching part 121, that is, when the second latching part 121 moves into the second segment 1333, the left and right directions are limited, and the second box 120 can be latched and connected to the rear edge of the second segment 1333 by continuing to move backward.

[0077] The aforementioned support structure, first connecting part 131, first limiting part 132 and first buckling part 133 can be formed by integral stamping, which has high production efficiency; and all parts are made of the same piece of material, making the connection between the structures more solid, without additional welding or bonding points, which can improve the overall structural strength.

[0078] In some embodiments, such as Figure 1 , Figure 2 and Figure 6 As shown, the first housing 110 has a downward-facing mounting cavity 113. The electrical component 150 is disposed within the mounting cavity 113, and there is a gap between the end of the electrical component 150 facing the opening and the mounting platform 130. Due to the orientation of the opening, any condensation formed on the inner wall of the housing or on the electrical component 150 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 component 150 due to long-term immersion in water.

[0079] The top wall of the first housing 110 can be used as a mounting base, and electrical components 150 can be directly mounted from the opening onto the top wall of the first housing 110 where the control components are pre-mounted. Specifically, each electrical component 150 can be mounted onto a circuit board, and then the circuit board can be fixed to the top wall of the first housing 110 using screws or other fasteners. The wiring and soldering of the electrical components 150 are performed on the outside of the first housing 110. The first housing 110 is mounted on the mounting plate 130a by inverting, without the need for additional components to close the opening.

[0080] like Figure 6 and Figure 7As shown, the front panel of the first housing 110 is provided with a cable outlet 115 and a docking terminal 116. The cable outlet 115 can be divided into a high-voltage cable outlet 115 and a low-voltage cable outlet 115. The high-voltage cable outlet 115, the low-voltage cable outlet 115 and the docking terminal 116 are connected to external electrical components or power sources in different ways.

[0081] like Figure 1 , Figure 2 and Figure 6 As shown, the first box body 110 is provided with a second connecting part 111 and a second limiting part 112. The second limiting part 112 cooperates with the first limiting part 132 to limit and determine the position of the first box body 110 before the first fastener 140 is locked. The second connecting part 111 and the first connecting part 131 are aligned along the first direction for the first fastener 140 to be locked.

[0082] The position of the second connecting part 111 is adapted to the position of the first connecting part 131. When the first connecting part 131 is arranged at intervals in the left and right direction, the second connecting part 111 can be provided on the left and right sides of the first box body 110. When the first connecting part 131 with a bottom groove is used, the second connecting part 111 can be provided on the left and right sides and the top of the first box body 110.

[0083] With the second housing 120 installed on the front side of the first housing 110, the second connecting part 111 should be exposed from the left and right sides of the second housing 120, so that all the first fasteners 140 can be directly exposed, making it easy to install or remove from the front side of the water heater 1000.

[0084] The position of the second limiting part 112 is adapted to the position of the first limiting part 132. The second limiting part 112 can be provided on the rear side of the first box 110, so that when installing the first box 110, the second box 120 can pass between the two first connecting parts 131, and then the first box 110 can be moved backward until the rear side of the first box 110 abuts against the limiting baffle 1321. At this time, the second limiting part 112 is inserted into the limiting hole 1322. The second limiting part 112 can also be provided on the left and right sides of the first box 110. In this case, it should be noted that when installing the first box 110, the second limiting part 112 should be placed between the first connecting part 131 and the first limiting part 132 to prevent the second limiting part 112 from interfering with the first connecting part 131. This application does not limit this.

[0085] like Figure 1 , Figure 2 and Figure 8As shown, at least a portion of the structure of the second limiting part 112 is inclined relative to the platform in a direction away from the first box 110. The second limiting part 112 is inserted into the limiting hole 1322 to limit the first box 110. The left and right edges and the top and bottom edges of the second limiting part 112 are limited by the inner wall of the limiting hole 1322, thereby limiting the first box 110 in the left and right and top and bottom directions. The inclined portion of the second limiting part and the rear side of the first box 110 cooperate with the limiting baffle 1321 to limit the first box 110 in the front and back directions.

[0086] In practical applications, the end of the second limiting part 112 furthest from the first box 110 can be tilted downwards. That is, when the first box 110 is placed on the mounting plate 130a, the bottom edge of the first box 110 is not completely flush with the mounting surface of the mounting plate 130a, but rather its rear side is raised. As the first box 110 is moved backwards, the tilted portion of the second limiting part 112 will first contact the limiting hole 1322 on the mounting plate 130a. As the first box 110 continues to move, the second limiting part 112 will gradually insert into the limiting hole 1322. Due to the tilted design, the rear side of the first box 110 will gradually descend as it moves until the tilted portion of the second limiting part 112 completely passes through the limiting hole 1322, and the bottom edge of the first box 110 will be completely flush with the mounting surface of the mounting plate 130a.

[0087] Conversely, when disassembling the first box 110, the rear end of the first box 110 needs to be lifted until the inclined part of the second limiting part 112 is completely disengaged from the first limiting hole 1322, and then the first box 110 is moved forward until the first box 110 is removed.

[0088] It should be noted that the inclined section of the second limiting part 112 can completely pass through the limiting hole 1322 and abut against the limiting baffle 1321 at the same position, or the inclined section of the second limiting part 112 can completely pass through the limiting hole 1322 and then continue to move the first box 110 backward until the rear end of the first box 110 abuts against the limiting baffle 1321; this application does not limit this.

[0089] The second limiting part 112 has rounded corners at both ends away from the edge of the first housing 110. When the first housing 110 moves backward to engage with the mounting plate 130a, the rounded corners of the second limiting part 112 will first contact the edge of the mounting plate 130a or the limiting hole 1322. Due to the rounded corner design, it can more smoothly guide the first housing 110 into the correct installation position and absorb errors in the left and right directions.

[0090] In other embodiments, the second limiting part 112 may also be a portion that is bent close to the first box body 110, and the bending direction may also be upward. This application does not limit this.

[0091] In some embodiments, such as Figure 1 , Figure 2 and Figure 9 As shown, the second box 120 is provided with a third connecting part 122 and a second latching part 121. The second latching part 121 engages with the first latching part 133 on the mounting plate 130a to determine the position of the second box 120 on the mounting plate 130a. The third connecting part 122 is aligned with the second connecting part 111 along the first direction to facilitate the locking of the first fastener 140.

[0092] The position of the third connecting part 122 is adapted to the position of the second connecting part 111. The following description takes the second connecting part 111 being located on the left and right sides of the first box 110 as an example.

[0093] like Figure 1 and Figure 4 As shown, the third connecting part 122 is located on the left and right sides of the second housing 120, and the third connecting part 122 and the first connecting part 131 are offset in the vertical direction. That is, the lower half of the first connecting part 131 and the second connecting part 111 are connected by a fastener, and the upper half of the third connecting part 122 and the second connecting part 111 are connected by another fastener. Thus, there is a gap between the third connecting part 122 and the mounting plate 130a, and the fastener connecting the second connecting part 111 and the first connecting part 131 can be exposed through this gap, thereby directly contacting the first housing 110 and the mounting plate 130a for fixation, realizing the scheme of the first housing 110 and the second housing 120 moving forward and separating from the mounting plate 130a.

[0094] In other embodiments, the first connecting portion 131 may be configured as a bent structure, such that the first connecting portion 131 is connected to the upper half of the second connecting portion 111 by a fastener, and the third connecting portion 122 is connected to the lower half of the second connecting portion 111 by another fastener. The bent structure is used to avoid the first fastener 140 connecting the third connecting portion 122 and the second connecting portion 111. Alternatively, the second connecting portion 111 may be divided into left and right parts, with the first connecting portion 131 connected to one of the parts by a first fastener 140, and the third connecting portion 122 connected to the other part by another first fastener 140. This application does not limit this.

[0095] like Figure 2 , Figure 9 and Figure 10As shown, the second latching part 121 is located at the bottom of the second box body 120. Part of the structure of the second latching part 121 is bent along the first direction to form a slot 1211. The second box body 120 has a first state and a second state. The second latching part 121 can pass through the latch so that the bottom surface of the second box body 120 is supported on the mounting plate 130a. At this time, the second box body 120 is in the first state. When the second box body 120 is moved backward, the edge structure of the latch can be engaged with the slot 1211, thereby engaging with the second latching part 121. At this time, the second box body 120 is in the second state. In the second state, the position of the second box body 120 on the mounting plate 130a is determined. The third connecting part 122 is aligned with the second connecting part 111 along the first direction for locking by the first fastener 140.

[0096] Conversely, when the second box 120 is in the second state, moving the second box 120 forward can disengage the edge of the latch from the slot 1211, thereby releasing the latch connection and returning the second box 120 to the first state; in the first state, the second box 120 can be moved upward to completely disengage the second latch 121 from the latch, and then the second box 120 can be moved forward to disassemble the second box 120.

[0097] Specifically, the second housing 120 includes two side plates arranged opposite each other in the left-right direction, a top plate connecting the top edges of the two side plates, and a front plate at the front edges of the two side plates; a second latching part 121 is provided at the bottom of the two side plates, and the bottom of the front plate has a notch, thereby forming a through-channel for cables in the front-back direction, facilitating the passage of cables from the outlet 115 and cables connected to the mating terminal 116. The portion of the front plate above the notch is used to cover the wiring terminal and the outlet 115, and a wire clamp can also be provided on the front plate for organizing the wire harness.

[0098] Additionally, this application also provides a water heater. In some embodiments, such as Figure 3 As shown, the water heater 1000 includes a housing 200, a cover 300, and the aforementioned control box assembly. The cover 300 is detachably connected to the housing 200 and forms an installation space 400. At least the first box 110 and the second box 120 are disposed within the installation space 400, serving to provide waterproofing and dustproofing. Thanks to the improvements made to the control box assembly 100 in the above embodiments, the water heater 1000 of this application embodiment has the same technical effects as the control box in the above embodiments, which will not be repeated here.

[0099] Depending on the installation method, the water heater 1000 can be a wall-mounted water heater or a floor-standing water heater. By installing the water heater 1000 inside the cabinet, the cabinet door can be opened to install, disassemble, and wire the cover and electrical control box components. When the installation is completed, the cabinet door can be closed to cover the water heater 1000 and prevent it from being directly exposed to the outside and damaged or accidentally touched, which could lead to a safety accident.

[0100] In one embodiment, such as Figures 1 to 3 As shown, the cover 300 is configured to move along a first direction to detach from the housing 200. The cover 300 can also be removed from the front of the water heater 1000. The operating path of the cover 300 is coordinated with the installation and removal paths of the first housing 110, the second housing 120, and the first fastener 140, meaning that all these components can be operated from the same side of the water heater 1000 without reserving additional operating space in multiple directions. This greatly improves space utilization efficiency, allowing the water heater 1000 to flexibly adapt to the installation requirements of compact spaces such as cabinets.

[0101] It should be noted that the movement of the cover 300 along the first direction to detach from the box 200 in this application does not mean that the limiting and releasing of the limiting between the cover 300 and the box 200 are achieved by moving in the opposite or forward direction along the first direction. In practical applications, a first limiting member 210 can be provided on the rear side of the box 200, and a second limiting member 310 can be provided on the rear side of the cover 300. By moving the cover 300 backward, the first limiting member 210 and the second limiting member 310 are engaged to achieve limiting in the up-down and left-right directions; conversely, moving the cover 300 forward releases the engagement of the first limiting member 210 and the second limiting member 310. Alternatively, a first limiting member 210 can be provided at the top of the housing 200, forming a downwardly snapping cavity with the cover 300. A second limiting member 310 is provided on the inner wall of the cavity. By rotating clockwise or counterclockwise, the first limiting member 210 and the second limiting member 310 are engaged or disengaged. In this case, after disengaging the limiting member, the cover 300 needs to be moved upward so that the bottom edge of the cover 300 is higher than the first electrical control box. Then, when the first limiting box is moved forward, the cover 300 is completely disengaged from the housing 200. Understandably, no operating space needs to be reserved on the left, right, and rear sides for the rotation operation.

[0102] The first limiting member 210 and the second limiting member 310 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.

[0103] Based on the above embodiments, the water heater 1000 further includes a second fastener 500. The second fastener 500 connects the cover 300 and the housing 200 on one side along the first direction, and the central axis of the second fastener 500 is set along the first direction. Similar to the first fastener 140, the locking and releasing operations of the second fastener 500 also follow the same installation and disassembly logic as the first housing 110 and the second housing 120, that is, all related 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.

[0104] 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.
