Description

Technical Field

[0001] This utility model relates to the field of hot water supply equipment technology, and in particular to a wall-hung boiler. Background Technology

[0002] A wall-hung boiler is a type of heating and hot water supply equipment that uses gaseous fuels such as natural gas, liquefied petroleum gas, or manufactured gas as energy sources. It heats water in a heat exchanger through combustion, thereby providing domestic hot water and heating hot water for households or small buildings.

[0003] Specifically, the wall-hung boiler's casing includes a back panel, top panel, bottom panel, side panels, and front panel. The top panel, bottom panel, and side panels are connected to the perimeter of the back panel, forming an open mounting cavity. Components such as the boiler's electrical control box are installed within this cavity through the opening. The front panel is detachably connected to the top panel, bottom panel, and side panels, and the opening is sealed. Therefore, when the electrical control box needs replacement or repair, the front panel must be opened to remove it for maintenance. However, due to the large size of the front panel and the need to disassemble the fasteners around its perimeter, as well as disconnect the display screen's wiring, the disassembly and installation process is relatively cumbersome. This increases the time required for subsequent electrical control box maintenance, reducing work efficiency. Utility Model Content

[0004] This utility model provides a wall-hung boiler whose electrical control box is easy to disassemble, which can improve the efficiency of electrical control box maintenance.

[0005] The above-mentioned technical problems are solved by the following technical solutions: A wall-mounted boiler includes: a shell and an electrical control box, the electrical control box having a first end and a second end disposed opposite to each other, the second end being fixedly connected to a mounting plate; the bottom plate of the shell has a mounting opening, the first end and the second end extending sequentially into the shell through the mounting opening, the mounting plate being detachably and fixedly connected to the outer side of the bottom plate; or, the side plate of the shell has a mounting opening, the first end and the second end extending sequentially into the shell through the mounting opening, the mounting plate being detachably and fixedly connected to the outer side of the side plate.

[0006] Compared with the prior art, the wall-hung boiler described in this utility model has the following advantages: By setting an installation port on the bottom plate or side plate of the shell, and utilizing the detachable connection between the mounting plate at the second end of the electrical control box and the outer side of the bottom plate or side plate, this utility model effectively solves the cumbersome problem of disassembling a large panel and display screen connection cable required for maintaining the electrical control box of conventional wall-hung boilers. Specifically, when the electrical control box needs to be replaced or repaired, this utility model does not require disassembling the panel. Simply disconnecting the mounting plate from the outer side of the bottom plate or side plate allows the electrical control box to be directly removed from the shell through the installation port. This reduces the number of disassembly and installation steps, avoids the extra time spent removing the panel and connection cable, shortens the overall maintenance time of the electrical control box, and improves maintenance efficiency. Furthermore, since this utility model does not require touching the panel, display screen, or other components, it reduces the risk of damage to other structures of the wall-hung boiler during maintenance, further ensuring the safety and convenience of maintenance operations, and providing great convenience for subsequent long-term equipment maintenance. In addition, the electrical control box is fixed to the housing by a mounting plate. On the one hand, this ensures the installation stability of the electrical control box during the operation of the wall-hung boiler, preventing the electrical control box from shifting or loosening due to factors such as equipment vibration, thus ensuring the normal operation of the wall-hung boiler. On the other hand, this fixing method makes the mounting plate and the electrical control box form a relatively independent module. During the initial assembly or later maintenance, the electrical control box can be quickly disassembled and assembled by operating the entire mounting plate, optimizing the work efficiency of assembly and maintenance, and also reducing the wear and tear on the housing and other components caused by repeated disassembly and assembly.

[0007] In one embodiment, the electrical control box is slidably connected to the housing, and the sliding direction of the electrical control box is consistent with the direction in which the electrical control box enters and exits the housing through the mounting port.

[0008] In one embodiment, the housing is provided with a pair of first sliding members extending along the sliding direction of the electronic control box, and the opposite sides of the electronic control box are respectively provided with second sliding members corresponding one-to-one with the pair of first sliding members, and the second sliding members are slidably connected to the first sliding members.

[0009] In one embodiment, the first slider is provided with a slide rail extending along the sliding direction of the electronic control box, and the second slider includes a slider, a portion of which passes through the slide rail and is slidably connected to the slide rail.

[0010] In one embodiment, the first sliding member includes a first plate and a second plate, the second plate being perpendicular to the first plate and located at one end of the first plate near the mounting opening; the slide rail is disposed on the first plate, and the second plate is located on the periphery of the mounting opening and connected to the housing.

[0011] In one embodiment, the slide rail has an opening at one end near the mounting port, the size of the opening being greater than or equal to the size of the slider, and the second plate is offset from the opening along a direction perpendicular to the first plate and the second plate.

[0012] In one embodiment, the second slider further includes a connecting plate arranged parallel to the first plate, one end of the connecting plate being connected to the side wall of the electrical control box, and the other end extending away from the electrical control box, with the slider located at the end of the connecting plate away from the electrical control box.

[0013] In one embodiment, the mounting plate has a plurality of connecting ears on its periphery, and the mounting plate is connected to the outer side of the housing by fasteners passing through the connecting ears.

[0014] In one embodiment, the mounting plate covers the mounting opening, and the outer surface contour of the mounting plate is adapted to the outer surface contour of the housing side plate or bottom plate.

[0015] In one embodiment, the connecting ear includes a first connecting segment and a second connecting segment arranged at an angle.

[0023] The following is combined Figures 1 to 8 The following describes embodiments of the present invention.

[0024] According to embodiments of the present invention, such as Figure 1 , Figure 2 , Figure 4 , Figure 6 as well as Figure 8 As shown, a wall-hung boiler is provided, including: a housing 1 and an electrical control box 2.

[0025] Specifically, the electrical control box 2 has a first end and a second end that are arranged opposite to each other, and the second end is fixedly connected to the mounting plate 3; the bottom plate 101 of the housing 1 is provided with a mounting port 103, and the first end and the second end extend into the housing 1 through the mounting port 103 in sequence, and the mounting plate 3 is detachably and fixedly connected to the outer side of the bottom plate 101.

[0026] This embodiment effectively solves the cumbersome problem of disassembling a large panel 104 and display screen connection cable when maintaining the control box 2 of a conventional wall-hung boiler by providing an installation port 103 on the bottom plate 101 or side plate 102, and utilizing the detachable connection between the mounting plate 3 at the second end of the control box 2 and the outer side of the bottom plate 101 or side plate 102. Specifically, when the control box 2 needs to be replaced or repaired, this embodiment does not require disassembling the panel 104. Simply disconnecting the mounting plate 3 from the outer side of the bottom plate 101 or side plate 102 allows the control box 2 to be directly removed from the housing 1 through the installation port 103. This reduces the number of disassembly and installation steps, avoids the extra time spent removing the panel 104 and connection cable, shortens the overall maintenance time of the control box 2, and improves maintenance efficiency. Furthermore, since this invention does not require touching the panel 104 or display screen and other components, it reduces the risk of damage to other structures of the wall-hung boiler during maintenance, further ensuring the safety and convenience of maintenance operations, and providing great convenience for subsequent long-term equipment maintenance. Furthermore, in this embodiment, the electrical control box 2 is fixed to the housing 1 by the mounting plate 3. On the one hand, this ensures the installation stability of the electrical control box 2 during the operation of the wall-hung boiler, preventing the electrical control box 2 from shifting position or loosening due to factors such as equipment vibration, thus ensuring the normal operation of the wall-hung boiler. On the other hand, this fixing method makes the mounting plate 3 and the electrical control box 2 form a relatively independent module. During the initial assembly or later maintenance, the electrical control box 2 can be quickly disassembled and assembled by operating the entire mounting plate 3, optimizing the efficiency of assembly and maintenance. At the same time, it can also reduce the wear and tear on the housing 1 and other components caused by repeated disassembly and assembly.

[0027] Specifically, the connection method between the electrical control box 2 and the mounting plate 3 can be, but is not limited to, a fixed connection or a detachable connection, as long as the two can be connected together to form a whole. This utility model does not make any specific limitations in this regard.

[0028] In other embodiments, an installation port may be provided on the side plate 102 of the housing 1, and the first end and the second end may be inserted into the housing 1 through the installation port in sequence, and the mounting plate 3 may be detachably and fixedly connected to the outer side of the side plate 102.

[0029] Specifically, the connection between the mounting plate 3 and the bottom plate 101 or side plate 102 of the housing 1 can be, but is not limited to, screw connection or snap connection.

[0030] It should be noted that the improvement of this utility model lies in the disassembly and assembly method of the electrical control box 2, and does not involve improvements to other structures of the wall-hung boiler, such as the combustion structure or the hot water structure. In other words, other structures of the wall-hung boiler are not the improvement points of this utility model. Therefore, the unmodified structures in the wall-hung boiler can be conventional structures in the art.

[0031] In one embodiment, such as Figure 1 As shown, the shielding area of ​​the mounting plate 3 is greater than or equal to the cross-sectional area of ​​the mounting opening 103 on the housing 1. This arrangement allows a relatively sealed space to be formed inside the housing 1, preventing external impurities from entering the housing 1 through the gap between the mounting plate 3 and the mounting opening 103.

[0032] In one embodiment, such as Figure 2 , Figure 3 , Figure 6 , Figure 7 as well as Figure 8 As shown, the electrical control box 2 is slidably connected to the housing 1, and the sliding direction of the electrical control box 2 is consistent with the direction in which the electrical control box 2 enters and exits the housing 1 through the mounting port 103. It can be understood that when the electrical control box 2 inside the housing 1 of the wall-hung boiler needs to be repaired or replaced, by opening the mounting port 103, the operator does not need to disassemble the entire housing 1. They only need to smoothly pull the electrical control box 2 towards the mounting port 103 along the preset sliding direction, thus exposing the electrical control box 2 completely to the outside of the housing 1. At this time, whether checking for loose wiring connections, replacing damaged electronic components, or directly replacing the entire electrical control box 2, it can all be completed in a spacious operating area. After the repair or replacement work is completed, the electrical control box 2 is placed back into the mounting port 103, and then pushed back to its initial position along the preset sliding direction. Finally, the mounting plate 3 is used to close the mounting port 103 to restore the normal assembly state of the wall-hung boiler. The entire process not only shortens the repair time but also effectively avoids component damage or assembly errors that may result from excessive disassembly of the housing 1.

[0033] In one embodiment, such as Figure 2 , Figure 3 , Figure 6 , Figure 7 as well as Figure 8As shown, the housing 1 has a pair of first sliding members 4 extending along the sliding direction of the control box 2. On opposite sides of the control box 2 are second sliding members 5 corresponding to the pair of first sliding members 4, and the second sliding members 5 are slidably connected to the first sliding members 4. Along the sliding direction of the control box 2, the orthographic projection of the second sliding member 5 towards the mounting opening 103 falls within the orthographic projection range of the mounting opening 103. It can be understood that the sliding cooperation of the first sliding members 4 and the second sliding members 5 allows the control box 2 to smoothly enter and exit the housing 1 through the mounting opening 103, improving the convenience of installing and disassembling the control box 2. Furthermore, the sliding track structure formed by the cooperation of the first sliding members 4 and the second sliding members 5 not only guides the control box 2, ensuring it moves smoothly along a preset path during entry and exit from the housing 1, avoiding component collisions or jamming due to deviation, but also effectively limits the movement of the control box 2. When the control box 2 is in the working position, the sliding structure restricts its sway amplitude, increasing its installation stability.

[0034] In one embodiment, such as Figure 2 , Figure 3 , Figure 6 , Figure 7 as well as Figure 8 As shown, the first sliding member 4 is provided with a slide rail 401 extending along the sliding direction of the electrical control box 2, and the second sliding member 5 includes a slider 501, a portion of which passes through the slide rail 401 and is slidably connected to the slide rail 401. This arrangement limits the movement trajectory of the electrical control box 2, ensuring it maintains stable linear motion during its movement in and out of the housing 1, effectively avoiding problems such as deviation and jamming. Furthermore, the structural design of the slide rail 401 and the slider 501 makes the sliding action smoother and less strenuous, improving the ease of installation and disassembly of the electrical control box 2.

[0035] In one embodiment, such as Figure 2 , Figure 3 , Figure 6 , Figure 7 as well as Figure 8As shown, the first sliding member 4 includes a first plate 402 and a second plate 403. The second plate 403 is perpendicular to the first plate 402 and located at one end of the first plate 402 near the mounting opening 103. A slide rail 401 is disposed on the first plate 402, and the second plate 403 is located on the periphery of the mounting opening 103 and connected to the housing 1. It can be understood that by perpendicularly arranging the second plate 403 to the first plate 402, the structural strength of the first sliding member 4 is enhanced, effectively resisting external impacts and deformations generated during the disassembly and assembly of the electrical control box 2, preventing damage to the sliding structure due to long-term use or improper operation, and extending the service life of the component. Furthermore, compared to connecting the first plate 402 separately to the housing 1, this embodiment connects the second plate 403 to the housing 1, increasing the connection area between the first sliding member 4 and the housing 1, thereby making the connection between the first sliding member 4 and the housing 1 more secure and dispersing the pressure on the connection point.

[0036] For example, in one instance, the second plate 403 is connected to the inner wall of the housing 1 by fasteners.

[0037] In one embodiment, such as Figure 3 and Figure 7 As shown, the slide rail 401 has an opening 4011 at one end near the mounting port 103. The size of the opening 4011 is greater than or equal to the size of the slider 501. Along a direction perpendicular to the first plate 402 and the second plate 403, the second plate 403 is offset from the opening 4011. It can be understood that by providing an opening 4011 with a size greater than or equal to that of the slider 501 at one end of the slide rail 401 near the mounting port 103, this embodiment facilitates the slider 501's quick insertion or removal from the slide rail 401 through the opening 4011, improving assembly and disassembly efficiency. Simultaneously, the offset arrangement of the second plate 403 from the opening 4011 prevents the second plate 403 from obstructing or hindering the slider 501's entry and exit from the opening 4011, ensuring that the functionality of the opening 4011 is not affected by the second plate 403.

[0038] In one embodiment, such as Figure 7As shown, the second sliding member 5 also includes a connecting plate 502 arranged parallel to the first plate 402. One end of the connecting plate 502 is connected to the side wall of the electrical control box 2, and the other end extends away from the electrical control box 2. The slider 501 is located at the end of the connecting plate 502 away from the electrical control box 2. It can be understood that the connecting plate 502 provides an independent and stable mounting carrier for the slider 501, avoiding damage to the connection part caused by concentrated force when the slider 501 is directly connected to the side wall of the electrical control box 2, ensuring that the slider 501 maintains a stable installation state during long-term sliding, and reducing the risk of component loosening. By placing the slider 501 at the end of the connecting plate 502 away from the electrical control box 2, the slider 501 can be more accurately aligned with the slide rail 401 on the housing 1, reducing spatial interference between the side wall of the electrical control box 2 and other components inside the housing 1, making the electrical control box 2 slide more smoothly along the mounting opening 103, avoiding jamming, and further improving the convenience of assembly and disassembly.

[0039] In one embodiment, such as Figures 4 to 6 As shown, the mounting plate 3 has multiple connecting ears 301 on its periphery. The mounting plate 3 is connected to the outer surface of the housing 1 by fasteners passing through the connecting ears 301. On the one hand, the distributed layout of the multiple connecting ears 301 can evenly distribute the force on the mounting plate 3 to multiple connection points of the housing 1, avoiding deformation of the mounting plate 3 or damage to the housing 1 caused by excessive local force, and improving the stability of the connection between the mounting plate 3 and the housing 1. On the other hand, the detachable connection achieved by the fasteners can ensure the connection strength and facilitate the quick assembly and disassembly of the mounting plate 3.

[0040] In one embodiment, such as Figures 4 to 6 As shown, multiple connecting ears 301 are located on opposite sides of the mounting plate 3 and are arranged opposite each other. This arrangement ensures uniform force distribution and avoids stress concentration.

[0041] In one embodiment, such as Figure 1 As shown, the mounting plate 3 covers the mounting opening 103, and the outer surface contour of the mounting plate 3 is adapted to the outer surface contour of the side plate 102 or the bottom plate 101 of the housing 1. This arrangement allows the mounting plate 3 and the housing 1 to be better integrated in appearance, maintaining the overall integrity of the product's appearance.

[0042] In one embodiment, such as Figure 5As shown, the connecting ear 301 includes a first connecting segment 3011 and a second connecting segment 3012 arranged at an angle. One end of the first connecting segment 3011 is connected to the mounting plate 3, and the other end is connected to the second connecting segment 3012 and faces away from the housing 1. The second connecting segment 3012 is attached to the outer side of the housing 1 and connected to the housing 1 by fasteners. This arrangement can, on the one hand, avoid interference between the connecting ear 301 and the housing 1 during installation, and on the other hand, improve the fit between the mounting plate 3 and the mounting opening 103, reducing the abruptness of the housing 1's appearance.

[0043] 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.

[0044] 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.
