[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] In the description of this utility model, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] According to embodiments of the present invention, such as Figures 1 to 7 As shown, a thermostat mounting structure is provided, including: a maintenance cover 4, a thermostat 5, and a cover body 3. The thermostat 5 and the cover body 3 are respectively disposed on the inner side and the outer side of the maintenance cover 4. The thermostat 5 includes a thermostat body 501 and a reset mechanism disposed on the thermostat body 501. The thermostat body 501 is located on the inner side of the maintenance cover 4, and the reset mechanism extends from the inner side to the outer side. The cover body 3 is located on the outer side of the maintenance cover 4 and is detachably connected to the maintenance cover 4. The cover body 3 is used to cover the reset mechanism.

[0032] In this embodiment, a maintenance cover 4 is provided as the basic support structure for the thermostat mounting structure. The maintenance cover 4 includes a maintenance cover body 401 and a surrounding edge disposed around the maintenance cover body 401. The maintenance cover body 401 has an inner side and an outer side. The side of the maintenance cover 4 facing the inside of the water heater is the inner side, and the side facing the external environment is the outer side. The thermostat 5 is disposed on one side of the maintenance cover 4. The thermostat 5 includes a thermostat body 501 and a reset mechanism disposed on the thermostat body 501. The thermostat body 501 is the core part for realizing the temperature control function. It is located on the inner side of the maintenance cover body 401 so that the temperature can be monitored and controlled by related sensors or control circuits. The reset mechanism extends from the inner side of the maintenance cover body 401 to the outer side. When the thermostat 5 triggers over-temperature protection, the reset mechanism can be operated externally to reset the thermostat 5, thereby restoring the normal working state of the thermostat 5 without having to completely disassemble the entire maintenance cover 4, thus reducing the impact of disassembling the maintenance cover 4 on other components.

[0033] Furthermore, the cover 3 is positioned on the other side of the maintenance cover 4, located on the outer surface of the maintenance cover body 401. The cover 3 is detachably connected to the maintenance cover body 401 and is used to cover the reset structure to protect the reset mechanism from interference from the external environment. Moreover, when it is necessary to operate the reset mechanism, the cover 3 can be removed to expose the reset mechanism for corresponding operations, facilitating the user's operation and maintenance of the thermostat 5, thereby improving the maintenance efficiency of the thermostat 5 and reducing the maintenance workload. In addition, the removal of the cover 3 will not affect the internal components of the water heater, and will not cause the internal components to loosen or be damaged, thus avoiding secondary damage to the internal components.

[0034] like Figure 1 , Figure 2 As shown, in one embodiment, the maintenance cover 4 is recessed from the outer side to the inner side to form a mounting groove 406. The mounting groove 406 is provided with a connecting through hole 407 on the side near the thermostat 5. The reset mechanism extends into the mounting groove 406 through the connecting through hole 407.

[0035] In this embodiment, the surface of the maintenance cover body 401 is recessed from the outer side to the inner side to form a mounting groove 406, providing a space for the reset mechanism. When the reset mechanism extends from the inner side to the outer side, it can be placed in the mounting groove 406, which provides a certain degree of protection for the reset mechanism and does not affect the cooperation between the maintenance cover 4 and other components.

[0036] By providing a connecting through hole 407 on the side of the mounting groove 406 near the thermostat 5 to penetrate the maintenance cover body 401, the reset mechanism can pass through the maintenance cover body 401 and extend into the mounting groove 406, allowing the reset mechanism to perform corresponding operations within the mounting groove 406 without disassembling the entire maintenance cover 4, thus further improving the maintenance efficiency of the thermostat 5.

[0037] like Figure 3 , Figure 4 As shown, in one embodiment, the mounting groove 406 is provided with a positioning hole 404 on the side near the thermostat 5; the thermostat body 501 is provided with a positioning post 503 on the side near the mounting groove 406. The positioning post 503 is inserted into the positioning hole 404 so that the reset mechanism is aligned with the position of the connecting through hole 407 and extends through the connecting through hole 407 into the mounting groove 406.

[0038] In this embodiment, a positioning hole 404 is provided on the side of the mounting groove 406 near the thermostat 5, and a positioning post 503 is provided on the side of the thermostat body 501 near the mounting groove 406. The positioning post 503 cooperates with the positioning hole 404 to provide an accurate installation position for the positioning post 503 on the thermostat body 501, thereby fixing the position of the thermostat body 501 on the service cover 4. It also ensures that the reset mechanism of the thermostat 5 is aligned with the connecting through hole 407 on the service cover 4, allowing the reset mechanism to pass smoothly through the connecting through hole 407 and extend into the mounting groove 406. For example, during actual installation, the worker aligns the positioning post 503 on the thermostat body 501 with the positioning hole 404 in the mounting groove 406 on the service cover 4, and then presses the thermostat body 501 into place. At this time, the reset mechanism is perfectly aligned with the connecting through hole 407, allowing it to pass smoothly through the connecting through hole 407 and enter the mounting groove 406.

[0039] like Figures 5 to 7 As shown, in one embodiment, the maintenance cover 4 is provided with a first baffle 405 on the side near the cover body 3. The first baffle 405 is arranged around the mounting groove 406 and forms a first groove 408 with the inner wall of the mounting groove 406. The cover body 3 is provided with a second baffle 304 on the side near the maintenance cover 4. The second baffle 304 is arranged around the outer periphery of the cover body 3 and abuts against the first groove 408.

[0040] In this embodiment, a first retaining edge 405 is provided on the side of the maintenance cover body 401 near the cover body 3, and the first retaining edge 405 surrounds the mounting groove 406. The first retaining edge 405 and the inner wall of the mounting groove 406 together form a first groove 408. The first groove 408 provides installation space and positioning structure for the cover body 3, which helps to accurately install the cover body 3 on the maintenance cover body 401 and restricts the position and range of motion of the cover body 3 after installation. A second retaining edge 304 is provided on the side of the cover body 3 near the maintenance cover body 401, and the second retaining edge 304 surrounds the outer periphery of the cover body 3. The second retaining edge 304 can cooperate with the structure on the maintenance cover body 401 to realize the connection and positioning between the cover body 3 and the maintenance cover body 401. When the cover 3 is installed on the maintenance cover body 401, the second retaining edge 304 of the cover 3 abuts against the first groove 408 of the maintenance cover body 401, so that the cover 3 can be stably installed on the maintenance cover body 401, ensuring the stability of the cover 3 during use and preventing the cover 3 from shaking randomly on the maintenance cover body 401.

[0041] In one embodiment, the reset mechanism includes a control lever 504 and a reset button 502. The control lever 504 protrudes from the thermostat body 501 in a direction away from the thermostat body 501, and the reset button 502 is located on the top of the control lever 504.

[0042] In this embodiment, the control lever 504 in the reset mechanism protrudes from the thermostat body 501 in a direction away from the thermostat body 501, allowing the control lever 504 to extend into the mounting groove 406 through the connecting through hole 407 on the mounting groove 406. A reset button 502 is further provided on the top of the control lever 504. When the thermostat 5 triggers over-temperature protection, the reset button 502 pops up. At this time, the cover 3 is removed from the maintenance cover body 401 to expose the reset button 502 on the control lever 504. Then, pressing the reset button 502 resets the thermostat 5. Finally, the cover 3 is reinstalled on the maintenance cover body 401 to cover and protect the reset mechanism. Positioning the reset button 502 on the top of the control lever 504 allows the user to easily locate and operate the reset button 502 to complete the reset operation.

[0043] In one embodiment, the cover 3 is detachably connected to the maintenance cover 4 via locking screws.

[0044] In this embodiment, a first screw connection hole is provided on the cover 3, penetrating the cover 3 and providing an installation position for connecting the cover 3 and the maintenance cover 4. A second screw connection hole is provided on the maintenance cover body 401, the position and size of which correspond to the first screw connection hole on the cover 3, so that the connector 1 can smoothly pass through the two screw connection holes to achieve the connection between the cover 3 and the maintenance cover 4. After aligning the first and second screw connection holes, a locking screw is passed through the first screw connection hole and then through the second screw connection hole to connect the cover 3 and the maintenance cover 4 together. By loosening or removing the locking screw, the cover 3 can be easily removed from the maintenance cover 4. At the same time, during installation, the connector 1 can provide sufficient fastening force to ensure that the cover 3 is firmly installed on the maintenance cover 4 and will not easily loosen during use, ensuring the structural stability and reliability of the entire thermostat installation structure.

[0045] In other possible implementations, multiple first screw connection holes and multiple second screw connection holes are provided, thereby further increasing the stability of the connection between the cover 3 and the maintenance cover 4.

[0046] In one embodiment, the cover 3 is provided with a buckle, and the maintenance cover 4 is provided with a slot that engages with the buckle, so that the maintenance cover 4 and the cover 3 are engaged.

[0047] In this embodiment, the cover 3 may be provided with multiple buckles, all located on the side near the maintenance cover 4, and arranged at intervals along the circumference of the cover 3. Multiple slots are provided on the maintenance cover body 401, arranged at intervals along the circumference of the maintenance cover body 401, with each buckle corresponding to a slot. When the cover 3 is installed on the maintenance cover 4, the buckles on the cover 3 are aligned with the slots on the maintenance cover 4, extending to the inner side of the maintenance cover body 401, thereby achieving the engagement of the buckles and slots. This ensures that the cover 3 is securely connected to the maintenance cover 4 and will not easily separate during normal use.

[0048] In one embodiment, the cover 3 is provided with a first connecting hole 303 and a plurality of hooks 302, the plurality of hooks 302 being arranged at intervals along the circumference of the cover 3; the maintenance cover 4 is provided with a second connecting hole 403 and a plurality of snap-fit ​​holes 402, the plurality of snap-fit ​​holes 402 being arranged at intervals along the circumference of the maintenance cover 4, the snap-fit ​​holes 402 corresponding one-to-one with the hooks 302; the hooks 302 pass through the snap-fit ​​holes 402 and engage with the inner side of the maintenance cover 4; it also includes a connector 1, the connector 1 passing through the first connecting hole 303 and being connected to the maintenance cover 4 through the second connecting hole 403.

[0049] In this embodiment, the cover 3 is provided with a first connecting hole 303 and a plurality of hooks 302. The first connecting hole 303 penetrates the cover 3 and provides an installation position for connecting the cover 3 and the maintenance cover 4. The plurality of hooks 302 are all located on the side near the maintenance cover 4 and are arranged at intervals along the circumference of the cover 3. Each hook 302 includes a connecting part and a limiting part. One end of the connecting part is connected to the cover 3 and the other end is connected to the limiting part, which is located at the end near the maintenance cover 4. The maintenance cover body 401 is provided with a second connecting hole 403 and a plurality of snap-fit ​​holes 402. The position and size of the second connecting hole 403 correspond to the first connecting hole 303 on the cover 3 so that the connector 1 can pass smoothly through the two connecting holes to achieve the connection between the cover 3 and the maintenance cover 4. The plurality of snap-fit ​​holes 402 are arranged at intervals along the circumference of the maintenance cover body 401, and the hooks 302 and snap-fit ​​holes 402 correspond one-to-one.

[0050] When the cover 3 is installed on the maintenance cover 4, align the hook 302 on the cover 3 with the snap hole 402 on the maintenance cover 4, so that the hook 302 extends to the inner side of the maintenance cover body 401; then rotate the cover 3 so that the limiting part at the bottom of the hook 302 abuts against the inner wall of the maintenance cover body 401, thereby realizing the snap-fit ​​between the hook 302 and the snap hole 402, so that the position of the cover 3 on the maintenance cover 4 is initially fixed.

[0051] Optionally, multiple hooks 302 are all oriented clockwise, and the locking holes 402 are arc-shaped. During installation, the hooks 302 pass through the locking holes 402, and after rotating clockwise by a preset angle, the hooks 302 engage with the inner side of the maintenance cover body 401. At this time, the first connecting hole 303 and the second connecting hole 403 are aligned. Then, the connector 1 passes through the first connecting hole 303 and the second connecting hole 403 to connect the cover body 3 and the maintenance cover 4 together. The engagement of the hooks 302 and the fastening of the connector 1 further ensure the firmness and stability of the connection between the cover body 3 and the maintenance cover 4. When it is necessary to disassemble the cover body 3, the connector 1 can be removed first, and then the cover body 3 can be rotated in the opposite direction to release the engagement of the hooks 302 with the maintenance cover body 401. The cover body 3 can then be removed from the maintenance cover 4, so that when the thermostat 5 needs to be repaired, the cover body 3 and the maintenance cover 4 can be easily separated, thereby improving maintenance efficiency. The connector 1 can be a screw or bolt.

[0052] In one embodiment, a fastener 2 is also included, which is located on the outer side of the service cover 4 and is connected to the control lever 504 so that the thermostat 5 is detachably connected to the service cover 4.

[0053] In this embodiment, a second groove 409 is also provided within the mounting groove 406. The second groove 409 surrounds the connecting through hole 407 and is used to place the fastener 2. When the reset mechanism extends into the mounting groove 406, it can be detachably connected to the control rod 504 via the fastener 2 provided in the second groove 409, thereby detachably connecting the thermostat 5 to the maintenance cover body 401. The fastener 2 can be a nut. The control rod 504 of the reset structure has external threads, and the thermostat 5 is fixed to the maintenance cover body 401 by the cooperation of the external threads and the nut.

[0054] In other possible implementations, the thermostat 5 can also be fixedly installed inside the water heater. It can be connected to the water heater by welding or riveting, making the thermostat 5 an integral part of the water heater. This ensures that the thermostat 5 can work stably during water heater operation and will not move or loosen due to vibration or other external forces. When the thermostat 5 is abutted against the main body of the maintenance cover 4, allowing the reset mechanism to be accommodated within the mounting groove 406, the position of the reset mechanism can be kept relatively fixed, preventing significant shaking of the reset mechanism during water heater operation.

[0055] On the other hand, this utility model also provides a water heater, including a thermostat mounting structure. Since the water heater includes the aforementioned thermostat mounting structure and has the same effect as the thermostat mounting structure, it will not be described in detail here.

[0056] 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.

[0057] 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.
