[0035] This utility model proposes a water heater, typically a gas water heater, designed to improve the ease of installation and removal of the electrical control box. For ease of understanding and explanation, a description of this utility model is attached. Figures 1 to 5 In the diagram, solid arrows indicate spaces, slots, or holes.

[0036] Please see Figure 1 In one embodiment of this utility model, the water heater 10 includes a water heater body 100. In this embodiment, the water heater body 100 typically includes a shell, a burner, a heat exchanger, water pipes and a water system, a gas pipeline system, and an ignition device. The shell primarily protects the internal components and provides structural support, and usually includes a control panel; it is responsible for burning gas (natural gas, liquefied petroleum gas, etc.) to generate high-temperature heat. The heat exchanger transfers the heat generated by the burner to the flowing cold water, heating the water. The water pipes and water system include an inlet pipe, an outlet pipe, and internal water passages, used to guide and control the water flow. The gas pipeline system includes a gas inlet pipe and various valves, controlling the gas supply and flow rate. The ignition device is typically an electronic igniter, responsible for igniting the gas.

[0037] In order to manage and coordinate the various functions of the water heater 10, including ignition, combustion, temperature control and safety protection, the water heater 10 also includes an electrical control box assembly 300. The electrical control box assembly 300 typically includes a box body 340, a circuit board disposed in the box body 340, a sensor interface, control software and other electronic components, and is responsible for coordinating the various operations of the water heater 10.

[0038] Currently, in gas water heaters 10, the installation method of the electrical control box assembly 300 has two problems: when the control box needs to be replaced for after-sales maintenance, the screws need to be removed from the bottom, which is inconvenient; or, the position of the electrical control box assembly 300 blocks the internal components, and when these components need to be repaired, the entire electrical control box assembly 300 needs to be removed, which is time-consuming and laborious.

[0039] To address the aforementioned issues, in this example, the water heater 10 is equipped with a mounting bracket 200, which is located within the outer casing. Generally, the mounting bracket 200 is situated inside the casing, and the electrical control box assembly 300 is mounted on the mounting bracket 200 and engages with it via a snap-fit ​​connection. This snap-fit ​​connection is typically designed to eliminate the need for additional tools or screws; simply aligning and snapping the electrical control box assembly 300 and the mounting bracket 200 together greatly simplifies the installation process.

[0040] Furthermore, the mounting bracket 200 is provided with a first fastening component, and the electrical control box assembly 300 includes a box body 340 and a second fastening component disposed on the box body 340, wherein the second fastening component is fastened to the first fastening component.

[0041] The first fastening component can be a buckle 310, a slot 201, or a combination of buckle 310 and slot; the second fastening component is adapted to the first fastening component. That is, if the first fastening component is buckle 310, then the second fastening component is the slot 201 adapted to it; if the first fastening component is slot 201, then the second fastening component is buckle 310 adapted to it.

[0042] The technical solution of this embodiment is to set up the mounting bracket 200, and make the mounting bracket 200 and the box 340 fastened together by the fastening component. The fastening is usually designed so that no additional tools or screws are needed. The electrical control box assembly 300 and the mounting bracket 200 can be simply aligned and fastened together, which greatly simplifies the installation operation.

[0043] Compared to the direct snap-fit ​​connection between the control box assembly 300's housing 340 and the water heater 10's casing, the mounting bracket 200 typically makes the assembly and disassembly of the control box assembly 300 much easier. This is especially true during maintenance or replacement of the control box assembly 300, where bracket mounting allows for quick and easy disassembly and reinstallation. Direct snap-fit ​​connections, on the other hand, can make disassembly difficult and may even damage the snap-fit ​​structure of the control box assembly 300 or the casing. Furthermore, the mounting bracket 200 allows for some space between the control box assembly 300 and the water heater 10's casing, promoting airflow and improving heat dissipation. Direct snap-fit ​​connections, where the control box assembly 300 is in tight contact with the casing, can restrict heat dissipation, potentially causing the control box assembly 300 to overheat and affect its normal operation. By using the mounting bracket 200, designers can flexibly adjust the position and angle of the control box assembly 300 in different types of water heaters 10, optimizing space utilization and overall layout.

[0044] In one embodiment, the first fastening component includes a slot 201 and a first limiting slot 202, the first limiting slot 202 having a guide surface, and the second fastening component further includes a buckle 310 and a guide member 320, the guide member 320 being installed along the guide surface to the first limiting slot 202; the buckle 310 being engaged with the slot 201.

[0045] During installation, the guide 320 enters from the opening of the first limiting groove 202 and is then installed along the guide surface to the bottom of the first limiting groove 202, at which point the buckle 310 snaps into the slot 201.

[0046] In this embodiment, the guide surface in the first limiting groove 202 provides a clear directional guide, reducing the alignment difficulty during installation and ensuring that the electrical control box assembly 300 can be correctly connected and installed. Secondly, through the cooperation of the guide member 320 and the first limiting groove 202, the box body 340 can easily slide into the positioning along the predetermined track. The guide surface provides a clear directional guide, reducing the alignment difficulty during installation and enabling the box body 340 of the electrical control box assembly 300 to be correctly connected and installed. Thus, this design does not require additional tools or complicated fixing steps. Installers can complete the installation of the electrical control box assembly 300 through simple plug-in actions, greatly saving installation time and improving work efficiency.

[0047] The first limiting groove 202 is generally an inclined groove or an arc-shaped groove to serve its limiting function. Preferably, the first limiting groove 202 is arc-shaped. During installation or disassembly, the arc-shaped limiting groove can better distribute the force. Compared with a straight design, the arc design can gradually guide the electrical control box assembly 300 into the locking position, reducing the impact force caused by instantaneous docking and extending the service life of the fastening assembly. Secondly, the arc-shaped first limiting groove 202 can provide additional resistance after the electrical control box assembly 300 is installed, making it less likely to loosen or fall off under force, especially when subjected to vibration or external force, the stability of the electrical control box assembly 300 is better. In addition, the arc design is generally more aesthetically pleasing than the straight design, making the overall appearance smoother and more modern, while maintaining functionality.

[0048] In one embodiment, to improve the stability of the housing 340 during installation, the housing 340 has a first side and a second side, with the first side and the second side respectively provided with the buckle 310 and the guide 320. That is, the first side of the housing 340 is provided with the buckle 310 and the guide 320, and the second side of the housing 340 is provided with the buckle 310 and the guide 320.

[0049] In this embodiment, firstly, by setting buckles 310 and guide members 320 on both sides of the box body 340, double-sided support and alignment can be achieved during installation, making the box body 340 more secure after installation, less prone to loosening or displacement, and improving overall installation stability. Secondly, when the box body 340 is installed, the buckles 310 and guide members 320 are located on opposite sides, which can distribute the stress in all directions during installation, avoiding deformation or damage caused by uneven force on one side, and extending the service life of the components. The double-sided setting of buckles 310 and guide members 320 provides stronger fixing force for the box body 340. Especially when the equipment may encounter vibration or external impact, the double-sided fixing method can significantly improve the vibration resistance of the box body 340, ensuring stability during use.

[0050] Furthermore, the opposing double-sided guide members 320, used in conjunction with the limiting grooves, effectively prevent the housing 340 from shifting left or right or up or down during installation, making it easier to enter the correct position along the correct path, thus improving installation accuracy and efficiency. Since there is a guide member 320 on each side of the housing 340, installers can easily align it with the limiting groove of the mounting bracket 200 and slide the clip 310 into the slot 201, eliminating the need for additional adjustments or complex operations and simplifying the installation process.

[0051] As can be seen, in this embodiment, the fastening components on both sides not only increase the stability of the installation but also maintain convenient disassembly. By controlling the latches 310 or guides 320 on both sides respectively, maintenance personnel can easily disassemble and assemble the housing 340 for later maintenance and replacement, reducing maintenance time.

[0052] In one embodiment, the mounting bracket 200 includes two mounting members 210, which are respectively connected to the outer shell; one mounting member 210 is located on the first side of the electrical control box assembly 300, and the other mounting member 210 is located on the second side of the electrical control box assembly 300. The two mounting members 210 are respectively provided with the slot 201 and the first limiting slot 202 corresponding to the positions of the buckle 310 and the guide member 320.

[0053] In this embodiment, the mounting bracket 200 includes two mounting components 210, which are respectively connected to the outer shell. That is, the mounting bracket 200 is a separate unit, which can further improve the ease of disassembly and assembly of the electrical control box assembly 300 and the flexibility of the installation of the electrical control box assembly 300.

[0054] In one embodiment, to further improve the stability of the installation of the electrical control box assembly 300, the second fastening assembly further includes a limiting member 330 disposed on the guide member 320, the limiting member 330 being located at one end of the guide member 320 away from the electrical control box assembly 300; a second limiting groove 301 for the installation member 210 to be inserted is formed between the box body 340 and the limiting member 330.

[0055] In an exemplary embodiment, the mounting component 210 includes a mounting plate 211 and a connecting flange 214 disposed on the mounting plate 211. The first limiting groove 202 and the slot 201 are disposed on the mounting plate 211, and the connecting flange 214 is threadedly connected to the water heater body 100.

[0056] In this embodiment, the connecting flange 214 and the mounting plate 211 are formed from a single sheet metal part through processes such as bending, cutting, or stamping. Of course, they can also be formed from different sheet metal parts through processes such as welding.

[0057] Thus, in this embodiment, the design of the mounting plate 211 and the connecting flange 214 makes the installation process simpler. The connecting flange 214 is threaded to the water heater body 100, providing a simple and stable connection method without complicated tools and steps, giving the electrical control box assembly 300 a relatively stable installation foundation.

[0058] In one embodiment, the mounting plate 211 has a disassembly side and a limiting side. The opening of the first limiting groove 202 is located on the disassembly side of the mounting plate 211. The mounting plate 211 is provided with an avoidance portion 212 on the disassembly side corresponding to the position of the slot 201. The mounting plate 211 is provided with a limiting portion 213 on the limiting side.

[0059] The avoidance part 212 and the limiting part 213 can also be formed by bending, cutting or stamping processes from the sheet metal parts described in the above embodiments. Of course, they can also be formed by welding or other processes from different sheet metal parts.

[0060] In this embodiment, the clearance portion 212 makes installation and disassembly more flexible. During installation, when the guide member 320 is just inserted into the first limiting groove 202, the clearance portion 212 can reduce the obstruction of the buckle 310, making it easier for the buckle 310 to be inserted into the slot 201. During disassembly, since the clearance portion 212 does not conform to the box body 340 of the electrical control box assembly 300, it can provide a fulcrum for force application, facilitating the disengagement of the buckle 310 on the box body 340 from the slot 201 on the mounting plate 211. The limiting portion 213 not only provides a positioning function during installation, but also increases the stability of the water heater 10 during daily use, preventing displacement or loosening caused by vibration or external force, and improving the installation stability of the electrical control box assembly 300.

[0061] In one exemplary embodiment, please refer to Figure 1 The water heater body 100 includes an outer shell, which includes a bottom shell 110 and a top cover, and the mounting bracket 200 is disposed on the bottom shell 110.

[0062] The bottom shell 110 may include a back plate 111, or the bottom shell 110 may include a back plate 111 and a bottom plate 112, or the bottom shell 110 may include a back plate 111 and a side plate, or the bottom shell 110 may include a back plate 111, a bottom plate 112 and a side plate, or the bottom shell 110 may include a back plate 111 and a top plate, or the bottom shell 110 may include a back plate 111, a bottom plate 112, a top plate and a side plate. Theoretically, the mounting bracket 200 can be installed on any of the back plate 111, the side plate, the bottom plate 112 or the top plate. In practice, because the top plate has a higher temperature during actual use, it is generally not installed on the top plate.

[0063] Preferably, the mounting bracket 200 is disposed on the base plate 112.

[0064] In this embodiment, the mounting bracket 200 is placed on the base plate 112, which means the electrical control box assembly 300 is also placed on the base plate 112. Placing the electrical control box assembly 300 on the base plate 112 allows for a more compact and rational structure of the water heater 10, saving space and optimizing the internal layout. The lower bottom position keeps the electrical control box assembly 300 away from the high-temperature components of the water heater 10, reducing the risk of the electrical control box assembly 300 being affected by high temperatures and increasing overall safety. Secondly, the base plate 112 typically has good ventilation, which helps dissipate heat from the electrical control box assembly 300, preventing overheating of electronic components and improving the stability and safety of the electrical control system. Furthermore, the base plate 112 is generally far from potential water sources and steam, reducing the risk of moisture entering the electrical control box assembly 300, improving its waterproof and moisture-proof performance, and extending its service life.
