[0032] Embodiment 1

[0033] Reference Figures 1 to 5 , a water heater housing structure, comprising a main housing 1 and a front panel 2. The main housing 1 includes a bottom plate 11 and several side plates 12. The several side plates 12 are surrounded and connected to one end edge of the bottom plate 11, and cooperate with the bottom plate 11 to form an accommodation cavity 13. The accommodation cavity 13 can be used to install various internal components of the water heater, such as a burner 3, a fan assembly 4, a heat exchanger assembly 5, etc. One end of the side plate 12 away from the bottom plate 11 extends outward from the bottom plate 11 to enclose and form a packaging opening 14 communicating with the accommodation cavity 13. The front panel 2 can be detachably connected to the packaging opening 14 by means of clamping, bolts, etc., for opening or closing the packaging opening 14 forward.

[0034] The improvement of the present application lies in that: on the basis of providing the packaging opening 14, a maintenance opening 15 communicating with the accommodation cavity 13 laterally is additionally provided on the side plate 12 of the main housing 1. When it is necessary to open the front panel 2 to repair and detect the internal water heater components installed in the accommodation cavity 13, due to the existence of the maintenance opening 15, the opening degree of the accommodation cavity 13 is further increased, so that the maintenance personnel can access the accommodation cavity 13 laterally through the maintenance opening 15, thereby effectively avoiding part interference and performing maintenance and disassembly operations on the water heater components (such as the burner 3) installed deep in the accommodation cavity 13, reducing the maintenance difficulty.

[0035] Furthermore, in this embodiment, it further includes a cover plate 16 for opening or closing the maintenance opening 15. The cover plate 16 is detachably connected to the main housing 1 by fasteners. When maintenance is required, the maintenance personnel can easily open the cover plate 16 to expose the maintenance opening 15; after the maintenance is completed, the maintenance opening 15 is closed by closing the cover plate 16 to ensure the sealing and safety of the water heater.

[0036] It should be noted that, in addition to the solution of detachably connecting the main housing 1 through fasteners, the cover plate 16 can also be movably and rotatably connected to the main housing 1 in the form of a hinge. For example, the top end of the cover plate 16 is hinged to the main housing 1. However, for safety and sealing considerations in this embodiment, the implementation structure of "the cover plate 16 is detachably connected to the main housing 1 through fasteners" is preferably selected, and further optimization and improvement are carried out under this implementation structure.

[0037] Specifically, the cover plate 16 is formed with a covering surface 161 for covering and closing the maintenance opening 15. One end of the cover plate 16 is provided with a plug-in portion 162. Correspondingly, the main housing 1 is provided with a connection hole 17 and a positioning groove 18 for the plug-in portion 162 to be inserted and positioned. During use, the plug-in portion 162 on the cover plate 16 can be adaptively inserted into the positioning groove 18 on the main housing 1 to achieve the preliminary alignment and fixation of the cover plate 16. Subsequently, a threaded fastener (such as a bolt or a screw) is used to pass through the connection hole 17 of the cover plate 16 and the main housing 1 to tightly connect the cover plate 16 and the main housing 1 together, which not only ensures a certain structural stability and connection strength but also facilitates subsequent disassembly and reinstallation.

[0038] Furthermore, the positioning groove 18 is formed in the accommodating cavity 13. The covering surface 161 of the cover plate 16 extends outward to form the above-mentioned plug-in portion 162. During installation, the cover plate 16 can be inclined relative to the maintenance opening 15, and the plug-in portion 162 formed on the covering surface 161 is extended into the accommodating cavity 13 to complete the connection with the positioning groove 18. By "placing the positioning groove 18 inside the accommodating cavity 13 and the plug-in portion 162 extending into the accommodating cavity 13 to complete the connection with the positioning groove 18", the situation of "the positioning groove 18 is arranged outside the accommodating cavity 13 and interferes with the cover plate 16" is avoided, which is beneficial to maximizing the area of the maintenance opening 15. At the same time, through the above technical solution, after installation, the plug-in portion 162 and the positioning groove 18 will be placed inside the accommodating cavity 13, making the appearance of the housing more consistent and visually more beautiful and refreshing.

[0039] Considering that the current household kitchen layout is becoming more and more compact, and water heaters are generally installed in corners or at higher positions. For this reason, based on the design of "the positioning groove 18 is placed inside the accommodating cavity 13" in this embodiment, the positioning groove 18 is formed on the bottom plate 11 of the main housing 1, thereby limiting the plug-in direction between the plug-in portion 162 and the positioning groove 18. Since the positioning groove 18 is arranged on the bottom plate 11, during the installation process, the plug-in portion 162 needs to be horizontally inserted into the positioning groove 18, which is beneficial to the installation and disassembly of the cover plate 16 in the case of "the water heater is installed in a corner or at a higher position".

[0040] In addition, in this embodiment, the cover surface 161 of the cover plate 16 is formed with a first installation groove 163, the first installation groove 163 is closed around the maintenance port 15, and a sealing strip 164 is installed in the first installation groove 163. By providing a closed-loop first installation groove 163 on the cover surface 161 of the cover plate 16 and installing the sealing strip 164 therein, the sealing strip 164 surrounds the periphery of the maintenance port 15 to form a sealing barrier, which can greatly improve the sealing performance of the connection between the cover plate 16 and the maintenance port 15, and prevent the water vapor and gas inside the water heater from leaking out through the maintenance port 15. At the same time, good sealing performance helps to reduce the loss of heat inside the water heater and prevent external impurities such as dust and moisture from entering the water heater to corrode and damage the internal components of the device. It can also play a sound insulation effect and reduce the vibration and noise transmitted when the water heater is running.

[0041] In this embodiment, the sealing strip 164 is preferably made of rubber, silicone, TPE or other materials with good elasticity. When installed, it can abut against the outer wall surface of the main shell 1, thereby forming an almost seamless sealing interface, effectively preventing water, gas or other liquids from leaking from the gap between the cover plate 16 and the maintenance port 15.

[0042] In addition, in order to further prevent the heat inside the water heater from diffusing outward, in this embodiment, the cover surface 161 is recessed inward to form a second installation groove 165. The area of ​​the second installation groove 165 is close to the maintenance port and basically covers the maintenance port 15. A heat insulation layer 166 is installed in the second installation groove 165. The cover surface 161 is recessed inward to form the second installation groove 165, which not only provides an installation space for the heat insulation layer 166, but also helps to enhance the structural strength of the cover surface 161. The heat insulation layer 166 is made of heat insulation materials such as foam and ceramic fiber, which can reduce the heat transferred to the outside through the cover plate 16 and improve the thermal efficiency.

[0043] Embodiment 2
