[0023] Combination Figures 1 to 8 As shown, this utility model provides a side-opening concealed hinge structure for a faceplate 20, which is used in conjunction with a gas water heating device, including either a gas water heater or a wall-mounted boiler. The side-opening concealed hinge structure for the faceplate 20 includes a housing 10 and a faceplate 20. The faceplate 20 has a connecting end 210 and further includes a hinge assembly 30 connected between the housing 10 and the faceplate 20. The faceplate 20 is rotatable relative to the housing 10 and has a closed state and an open state. The hinge assembly 30 includes a first hinge component 310, a second hinge component 320, and a hinge shaft 330. The first hinge component 310 is installed... On the inner wall surface of the connecting end 210; the second hinge component 320 is installed on the inner wall surface of the housing 10; the second hinge component 320 has a receiving groove 324, the receiving groove 324 has an opening 325, the opening 325 is arranged outward; the second hinge component 320 is connected to the first hinge component 310 through the hinge shaft 330; when the face shell 20 is in the open state, the connecting end 210 is located in the receiving groove 324 and the first hinge component 310 is blocked by the second hinge component 320; when the face shell 20 is in the closed state, the connecting end 210 closes the opening 325.

[0024] Specifically, the main body of the gas-fired water heater is installed inside the housing 10. The faceplate 20 is connected to the housing 10 via the hinge assembly 30, allowing the faceplate 20 to be closed or opened relative to the housing 10, i.e., the faceplate 20 has a closed state and an open state. Regarding the structure of the hinge assembly 30, the hinge assembly 30 includes a first hinge component 310, a second hinge component 320, and a hinge shaft 330. The first hinge component 310 is installed on the inner wall surface of the connecting end 210, and the second hinge component 320 is installed on the inner wall surface of the housing 10. The second hinge component 320 is connected to the first hinge component 310 via the hinge shaft 330, allowing the first hinge component 310 to rotate relative to the second hinge component 320 around the hinge shaft 330. This application uses a hinge assembly 30 to connect the housing 10 and the front shell 20. Compared with the screw connection method of the prior art, it can easily open the front shell 20. The first hinge component 310 and the second hinge component 320 are respectively set on the inner wall surface of the front shell 20 and the inner wall surface of the housing 10. When the front shell 20 is in the closed state, the connecting end 210 closes the opening 325, so that the user cannot see the internal hinge assembly 30 from the outside of the housing 10, realizing a hidden design. Moreover, there are no screw installation marks. In appearance, it is just a combination of the front shell 20 and the housing 10, which increases the aesthetics.

[0025] When the faceplate 20 is in the open state, the connecting end 210 is located in the storage groove 324 and the first hinge component 310 is blocked by the second hinge component 320. During the rotation of the faceplate 20, the storage groove 324 is used to store the connecting end 210. The storage groove 324 provides sufficient space for the connecting end 210 to rotate, avoiding interference and collision between the storage groove 324 and the connecting end 210, increasing the opening angle of the faceplate 20, and facilitating subsequent after-sales maintenance. Moreover, the first hinge component 310 is blocked by the second hinge component 320, so the user can only see the first hinge component 310 at a specific angle when opening it. At most angles, the first hinge component 310 is not visible. The hidden design of the first hinge component 310 increases the aesthetics and also prevents foreign objects from entering the connection between the first hinge component 310 and the second hinge component 320, thus playing a protective role.

[0026] Regarding the structure of the second hinge component 320, in this embodiment, the second hinge component 320 includes a second mounting portion 321, a second connecting portion 322, and a second supporting portion 323. The second mounting portion 321 is mounted on the inner wall surface of the housing 10. One end of the second connecting portion 322 is connected to the second mounting portion 321. The second mounting portion 321 has multiple mounting holes, and bolts are passed through the mounting holes to securely mount the second mounting portion 321 on the inner wall surface of the housing 10, ensuring the stability of the entire hinge structure. The other end of the second connecting portion 322 is connected to the second supporting portion 323 to form the storage groove 324. The second supporting portion 323 is connected to the first hinge component 310 through the hinge shaft 330, forming an integral structure. The second supporting portion 323 has a second shaft hole adapted to the hinge shaft 330. The hinge shaft 330 passes through the shaft hole and hinges with the first hinge component 310, allowing the faceplate 20 to rotate flexibly. Furthermore, the surface of the second support portion 323 can be smoothed, reducing friction with the first hinge component 310 and extending the service life of the hinge structure.

[0027] In this embodiment, the second hinge component 320 after the second mounting part 321, the second connecting part 322, and the second supporting part 323 are connected is shaped like "]".

[0028] Furthermore, the faceplate 20 is located in front of the housing 10; the housing 10 has a door frame, which is connected to the second mounting part 321 by bolts; the bolt heads face forward. This design allows the operator to directly operate the bolts from the front before installing the faceplate 20 onto the housing 10, without needing to reach inside the housing 10 or operate from other complex angles, greatly improving the convenience of installation and disassembly. Simultaneously, the forward-facing bolt heads facilitate observation of the bolt tightness, ensuring a stable connection between the door frame and the second mounting part 321, thereby guaranteeing the stability and reliability of the entire side-opening door concealed hinge structure of the faceplate 20. Moreover, after the faceplate 20 is installed onto the housing 10, the bolts can be concealed using the faceplate 20.

[0029] In this embodiment, the other end of the second connecting portion 322 is provided with an upper portion and a lower portion. The lower portion is connected to the second supporting portion 323 so that an installation area 326 is formed between the upper portion and the upper part of the second supporting portion 323. The first hinge component 310 includes a first matching portion 312, which is located at the installation area 326 and the lower end of the first matching portion 312 abuts against the upper end of the second supporting portion 323.

[0030] Specifically, the above design enables a stable connection between the first hinge component 310 and the second hinge component 320. During the installation of the faceplate 20 onto the housing 10, the faceplate 20 is first fixed to the first hinge component 310, and similarly, the housing 10 is first fixed to the second hinge component 320. Then, by combining the first hinge component 310 and the second hinge component 320, the faceplate 20 is installed onto the housing 10. The first mating part 312 can be accurately placed within the mounting area 326, and its lower end abuts against the upper end of the second supporting part 323. The second supporting part 323 supports the first hinge component 310, ensuring the stability of the connection. Furthermore, the operator can observe the connection between the first hinge component 310 and the second supporting part 323 in the mounting area 326 from a specific angle, facilitating installation. Furthermore, the mounting area 326 formed between the upper part and the second support part 323 provides sufficient space for the installation of the first hinge component 310, making the installation process more convenient.

[0031] In this embodiment, the first hinge component 310 further includes a first mounting portion 311, which is connected to the first mating portion 312. The first mounting portion 311 is connected to the face shell 20 by bolts, with the bolt heads facing the second connecting portion 322. The first mounting portion 311 and the first mating portion 312 are connected to form an integral structure, and the bolts fix the first mounting portion 311 to the face shell 20, making it less prone to loosening or falling off. Furthermore, by positioning the bolt heads towards the second connecting portion 322, the second hinge component 320 can conceal them.

[0032] In this embodiment, the faceplate 20 is in a ready state relative to the housing 10 (i.e., the faceplate 20 is not yet installed on the housing 10). When the faceplate 20 is in the ready state, the faceplate 20 and the housing 10 are separated, the lower part of the hinge shaft 330 is inserted into the second support 323, and the upper part of the hinge shaft 330 is exposed in the mounting area 326. Compared with the conventional structure, the faceplate 20 is separated from the housing 10, which facilitates cleaning, maintenance, or repair of the faceplate 20 and the interior of the housing 10, eliminating the need for complex and restrictive work within the overall structure, and greatly improving the convenience and efficiency of operation. On the other hand, the lower part of the hinge shaft 330 is inserted into the second support part 323, while the upper part is exposed in the mounting area 326. This configuration ensures the basic positioning of the hinge shaft 330 in a specific location and provides flexible operating space for the subsequent reinstallation of the faceplate 20 and the housing 10. This allows workers to perform precise operations according to actual needs, ensuring the stable and reliable operation of the entire side-opening concealed hinge structure of the faceplate 20. The first matching part 312 is provided with a first shaft hole that matches the hinge shaft 330.

[0033] In this embodiment, the faceplate 20 also has a free end 220, which is connected to the housing 10 via a door lock mechanism.

[0034] Furthermore, the door lock mechanism includes a slot 410, a spring 420, and a locking member 430. The spring 420 is disposed within the slot 410 and has a locking position that matches the locking member 430. The slot 410 is disposed in the housing 10 or the free end 220, and the locking member 430 is correspondingly disposed in the free end 220 or the housing 10. When the front cover 20 is in the closed state, the locking member 430 is engaged in the locking position. When the front cover 20 is in the open state, the locking member 430 disengages from the locking position.

[0035] In this embodiment, the slot is provided in the housing, and the locking member is provided at the free end.

[0036] This door lock mechanism design makes the opening and closing of the faceplate 20 very convenient and stable. When it is necessary to close the faceplate 20, simply bring the free end 220 close to the housing 10, press the faceplate 20, and engage the locking element 430 with the locking position on the spring piece 420 to achieve a firm connection between the faceplate 20 and the housing 10. This ensures that the faceplate 20 will not be accidentally opened during use, thus guaranteeing the safety and stability of the internal structure.

[0037] Furthermore, the housing 10 has a door frame with a notch 110; when the front cover 20 is in the closed state, a portion of the front cover 20 is exposed through the notch 110. The portion of the front cover 20 exposed through the notch 110 provides the user with a convenient point of leverage for opening. The user only needs to gently pull the portion of the front cover 20 exposed through the notch 110 to disengage the locking member 430 from the latch on the spring 420, thereby smoothly opening the front cover 20.

[0038] This utility model also provides a gas-fired water heating device, including the side-opening door and hidden hinge structure of the front shell as described above.

[0039] This utility model is not limited to the above-described embodiments. If any modifications or variations to this utility model do not depart from the spirit and scope of this utility model, and if such modifications and variations fall within the scope of the claims and equivalent technologies of this utility model, then this utility model also intends to include such modifications and variations.
