[0037] The existing wall-mounted boiler panel display is fixed to the back cover with screws during installation, and then the entire assembly is installed onto the front shell. The front of the front shell is covered with glass, and adhesive strips or glue are needed to adhere the glass and the front shell. There will be gaps between the two. After the display screen is installed, the gaps will cause the display to be unclear. In addition, the lack of a seal between the display panel and the front shell after installation will affect the airtightness of the product.

[0038] This utility model proposes a wall-mounted boiler panel 100.

[0039] Please see Figures 1 to 8In one embodiment of the present invention, the wall-mounted boiler panel 100 includes a front cover 10, a front cover 20, a display element 31, and a rear cover 40. The front cover 10 has a first shell surface 101 and a second shell surface 102 disposed opposite to each other, and a first mounting opening 103 connecting the first shell surface 101 and the second shell surface 102. The front cover 20 covers the first mounting opening 103 from the first shell surface 101. The front cover 20 has a transparent viewing window 21. The display element 31 is located on the side of the front cover 20 near the second shell surface 102 and is disposed in the viewing window 21. The rear cover 40 covers the first mounting opening 103 from the second shell surface 102.

[0040] In this utility model, the wall-hung boiler panel 100 can serve as the front panel of the wall-hung boiler, and is used to install at the front end of the wall-hung boiler. The first shell surface 101 of the shell 10 can be the front end surface of the shell 10, and the second shell surface 102 of the shell 10 can be the rear end surface of the shell 10. The display element 31 can be used to display the set operating temperature of the wall-hung boiler, the system operating mode (e.g., displaying heating mode, hot water mode, standby mode, antifreeze protection mode), fault diagnosis information, etc. The viewing window 21 can be made of transparent tempered glass. Since the display element 31 is located in the viewing window 21, the information displayed by the display element 31 can be seen through the viewing window 21 for the user to obtain. Furthermore, the display element 31 can also be equipped with a touch interaction function. By pressing the viewing window 21, the user can transmit pressure to the touch interaction area of ​​the display element 31 to realize the operation of the wall-hung boiler. The front cover 20 and the rear cover 40 are respectively fitted onto the first mounting port 103. The two can cooperate to form a receiving cavity for accommodating the display element 31. Since the display element 31 is directly provided on the window portion 21, the display surface of the display element 31 can fit against the window portion 21 without any gap between them. Compared with the method of installing the display element 31 on the rear cover 40 and then fitting the rear cover 40 and the front cover 20 onto the first mounting port 103 respectively (fitting the first shell surface 101 and the second shell surface 102 onto the first mounting port 103 respectively), the assembly precision between the display element 31 and the window portion 21 is higher and it is easier to fit against the window portion 21, thereby improving the display effect of the display area of ​​the wall-mounted boiler panel 100.

[0041] The technical solution of this utility model provides a front cover 20 with a transparent viewing window 21, allowing the display component 31 to be positioned in the viewing window 21. When the display component 30 is assembled on the wall-mounted boiler panel 100 by the front cover 20 and the rear cover 40 respectively covering the first mounting port 103, the display component 31 is directly positioned in the viewing window 21 and installed in the first mounting port 103 along with the front cover 20. Compared to the method of setting the display component 31 in the rear cover 40 and then assembling the rear cover 40 with the front cover 20, the assembly precision of the display component 31 and the viewing window 21 is higher, and the display component 31 and the viewing window 21 are easier to fit together. This improves the display clarity and prevents gaps between the display component 31 and the viewing window 21, which could lead to poor display effects on the wall-mounted boiler panel 100.

[0042] During actual installation, the display component 31 can be fixed to the outer periphery of the window portion 21 so that the display component 31 fits against the window portion 21. Figure 3 , Figure 4 As shown, in one embodiment, the front cover 20 is provided with a first mounting portion 22 on the side near the second shell surface 102. The first mounting portion 22 is circumferentially disposed around the window portion 21, and the display component 31 is detachably mounted on the first mounting portion 22.

[0043] In this invention, since the viewing window 21 is transparent, the first mounting part 22 is arranged around the viewing window 21 instead of being directly mounted on the viewing window 21. This avoids the display component 31 and the front cover 20 being visible through the viewing window 21, thus preventing them from affecting the display effect of the wall-mounted boiler panel 100. In addition, when the viewing window 21 is made of tempered glass, the other parts of the front cover 20, except for the viewing window 21, can be made of sheet metal or injection molding material, making it easier to mount the first mounting part 22 on the front cover 20, thereby reducing the difficulty of mounting the first mounting part 22 on the front cover 20.

[0044] The first installation section 22 will be further explained below; please refer to [link / reference needed]. Figure 3 , Figure 4 Optionally, the first mounting part 22 includes a plug-in seat 221 and a first fastening seat 222. The display component 31 is provided with a latching protrusion 311 and a first fastening ear 312. The latching protrusion 311 is plugged into the plug-in seat 221, and the first fastening ear 312 is fastened to the first fastening seat 222 by a fastener.

[0045] The fasteners can be screws, and the connector 221 can be provided with slots 221a. Two connectors 221 can be provided, and two corresponding latches 311 of the display element 31 can be provided. When the latches 311 of the display element 31 are inserted into the corresponding slots 221a, the first fastening ear 312 of the display element 31 aligns with the first fastening seat 222. At this time, by inserting a screw into the first fastening ear 312 and tightening the screw thread, the first fastening ear 312 and the first fastening seat 222 are securely engaged, thereby enabling the detachable installation of the display element 31 on the front cover 20. Of course, in other embodiments, the connector 221 can be omitted, and the display element 31 can be installed directly through the engagement of the first fastening ear 312 and the first fastening seat 222; this is not limited here.

[0046] like Figure 3 , Figure 4 As shown, in one embodiment, the front cover 20 has a second mounting portion 23 on the side near the second shell surface 102. The wall-hung boiler panel 100 also includes an electrical control 32, which is detachably mounted on the second mounting portion 23. The electrical control 32 is electrically connected to the display component 31. The electrical control 32 can receive instructions from the display component 31 (e.g., when the display component 31 has touch interaction functionality, instructions can be transmitted through the display component 31), and can monitor data from various sensors inside the wall-hung boiler (water temperature, pressure, flame status) before sending it to the display component 31 for display. When the electrical control 32 is mounted on the front cover 20 via the second mounting portion 23, it can be mounted on the front cover 20 together with the display component 31. After the wall-hung boiler panel 100 is assembled, it is located within the accommodating cavity formed by the front cover 20 and the rear cover 40, thus improving the assembly efficiency of the wall-hung boiler panel 100.

[0047] The second installation section 23 will be described in further detail below. (Continue reading...) Figure 3 , Figure 4 The second mounting part 23 includes a positioning member 231 and a second fastening seat 232. The positioning member 231 is used to position the electrical control 32 in the second mounting part 23. The electrical control 32 is provided with a second fastening ear 321, which is fastened to the second fastening seat 232 by a fastener.

[0048] Similar to the installation of the display component 31, the fasteners used for installing the electrical control component 32 can also be screws. During installation, the electrical control component 32 is first positioned on the second mounting portion 23 using the positioning component 231, ensuring that the second fastening ear 321 aligns with the second fastening seat 232, achieving pre-positioning during installation. Then, screws are passed through the second fastening ear 321 to secure it to the second fastening seat 232, thus enabling the detachable installation of the electrical control component 32 on the front cover 20. Of course, in other embodiments, the positioning component 231 may be omitted, and only the second fastening ear 321 and the second fastening seat 232 may be provided; this is not a limitation.

[0049] The positioning component 231 will be further described below; please refer to [link / reference needed]. Figure 3 , Figure 4 In one embodiment, multiple positioning elements 231 are provided, and the multiple positioning elements 231 are spaced apart. Each positioning element 231 includes a positioning seat 231a and a positioning wall 231b protruding from the positioning seat 231a. The electronic control 32 is limited and disposed between the positioning walls 231b of the multiple positioning elements 231.

[0050] In this utility model, two positioning members 231 can be provided. The positioning seat 231a of each positioning member 231 can be attached to the side of the electrical control 32 facing the front cover 20. Each positioning member 231 can be provided with two positioning walls 231b. When the electrical control 32 has four side surfaces connected in sequence, a total of four positioning walls 231b can be attached to the four side surfaces of the electrical control 32 respectively, so that the electrical control 32 is limited between the four positioning walls 231b, realizing the positioning and cooperation between the electrical control 32 and the positioning member 231, thereby facilitating the electrical control 32 to be fastened to the second fastening seat 232 by fasteners.

[0051] To reduce the difficulty of installing the viewing window 21 and the installation cost of the front cover 20, the viewing window 21 and the front cover 20 can be assembled separately, such as... Figure 4 , Figure 5As shown, in one embodiment, the front cover 20 has a second mounting opening 201, and a fastener 24 is provided on the outer periphery of the second mounting opening 201. The fastener 24 is located on the side of the front cover 20 near the second shell surface 102. The window portion 21 includes a window portion body 211 and a first limiting portion 212 provided on the outer periphery of the window portion body 211. The window portion body 211 extends from the second mounting opening 201 toward the first shell surface 101, and the first limiting portion 212 is engaged between the outer edge of the second mounting opening 201 and the fastener 24. When the window body 211 extends from the second mounting port 201 toward the first shell surface 101, the extended side of the window body 211 can be flush with the first shell surface 101, thereby improving the integrity of the front end of the front cover 20. Furthermore, a first limiting part 212 is provided on the outer periphery of the window body 211. By engaging the first limiting part 212 between the outer edge of the second mounting port 201 and the fastener 24, the connection between the window body 21 and the front cover 20 is made more stable.

[0052] like Figure 3 , Figure 6 As shown, in one embodiment, the outer edge of the first mounting opening 103 is recessed from the first shell surface 101 toward the second shell surface 102, and the front cover 20 abuts against the second limiting part 11. With this configuration, when the front cover 20 is placed over the first mounting opening 103, the front cover 20 can be embedded into the second limiting part 11 and abut against it, so that the front end face of the front cover 20 is flush with the first shell surface 101 of the front cover 10, resulting in a stronger sense of integrity of the front end face of the wall-mounted boiler panel 100. Furthermore, a corresponding snap-fit ​​structure can be provided in the second limiting part 11 to pre-position the front cover 20 on the front cover 10, facilitating subsequent connection and fixation between the front cover 20 and the rear cover 40.

[0053] When installing the display component 31 and the electrical control component 32 at the first mounting port 103, in order to prevent the first mounting port 103 from being too large and causing insufficient structural strength of the face shell 10, this utility model can also set a reinforcing beam 12 at the first mounting port 103. By separating the mounting positions of the display component 31 and the electrical control component 32 by the reinforcing beam 12, the structural strength of the face shell 10 can be improved.

[0054] The following describes the method by which the rear cover 40 and the front cover 20 are fixed to the front shell 10. (See reference...) Figure 4 , Figure 7 , Figure 8As shown, optionally, the front cover 20 has a plurality of third fastening seats 25 on the side facing the rear cover 40, and the rear cover 40 has a plurality of fourth fastening seats. The plurality of third fastening seats 25 are connected to the plurality of fourth fastening seats one by one, and each of the fourth fastening seats is used to fasten to the fourth fastening seat by a fastener. The fastener can be a screw. When the front cover 20 is placed on the first mounting opening 103 from the first shell surface 101, and the rear cover 40 is placed on the first mounting opening 103 from the second shell surface 102, the plurality of third fastening seats 25 are connected to the plurality of fourth fastening seats one by one. A screw can be threaded through the fourth fastening seat and threaded to the third fastening seat 25, so that the front cover 20 and the rear cover 40 respectively abut against the face shell 10, thereby achieving a fastened connection between the front cover 20 and the rear cover 40 and the face shell 10.

[0055] To improve the sealing performance of the rear cover 40 and the front shell 10, the wall-hung boiler panel may optionally include a sealing ring 50. The sealing ring 50 is disposed between the second shell surface 102 of the front shell 10 and the rear cover 40, and is used to seal the second shell surface 102 and the rear cover 40. Since the rear cover 40 is disposed on the second shell surface 102, when the wall-hung boiler panel 100 is assembled onto the wall-hung boiler, the sealing ring 50 seals the second shell surface 102 and the rear cover 40. By separating the display 31 and the electrical control 32 from the internal environment of the wall-hung boiler through the rear cover 40, the airtightness of the assembly between the rear cover 40 and the front shell 10 can be improved, preventing the display 31 and the electrical control 32 from being affected by the internal environment of the wall-hung boiler.

[0056] like Figure 8 As shown, the rear cover 40 further includes a slot 41 on the side facing the front shell 10, and the sealing ring 50 is accommodated in the slot 41. This arrangement allows the sealing ring 50 to be pre-positioned on the rear cover 40 by being accommodated in the slot 41, facilitating the sealing of the connection between the second shell surface 102 and the rear cover 40 when the rear cover 40 is fastened to the front shell 10.

[0057] This utility model also proposes a wall-hung boiler, which includes a boiler body and a boiler panel 100. The specific structure of the boiler panel 100 is as described in the above embodiments. Since this wall-hung boiler adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here. The boiler panel 100 is installed on the boiler body and located at the front end of the boiler.

[0058] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model.
