Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0045] In the prior art, hot water equipment requires a display panel assembly, and screws are typically used to connect and secure the various components of the display panel assembly. This method increases labor and material costs, leading to additional production steps and increased labor hours. Furthermore, screw connections are prone to problems such as thread stripping and hole cracking, compromising the quality of the assembly.

[0046] In order to solve the above technical problems, the following Figures 1 to 11 , describing the embodiments of the present utility model.

[0047] According to an embodiment of the present invention, in one aspect, a display panel assembly is provided, including a display cover 1 , a display bottom shell 2 , and a bottom cover 3 .

[0048] Specifically, if Figure 1 and Figure 2 As shown, the display cover 1 includes an annular inner panel 101, wherein the annular inner panel 101 is used to connect with the shell 5 of the water heater (such as Figure 10 A plurality of first buckles 1011 are provided at intervals on the inner wall of the annular inner panel 101.

[0049] Specifically, if Figures 1 to 3 As shown, the display bottom housing 2 is installed in the accommodating cavity 102 surrounded by the annular inner panel 101. A plurality of first latching grooves 201 are provided on the outer wall of one end of the display bottom housing 2. The plurality of first latching grooves 201 are provided in a one-to-one correspondence with the first latches 1011. The display bottom housing 2 and the display cover 1 are connected by the first latching grooves 201 and the first latches 1011. A plurality of second latches 202 are provided on the inner wall of the other end of the display bottom housing 2.

[0050] Specifically, if Figures 1 to 4 As shown, the bottom cover 3 is mounted on the display bottom housing 2. A plurality of second latching slots 301 are defined on the outer wall of the bottom cover 3. These second latching slots 301 correspond to the second latches 202. The bottom cover 3 and the display bottom housing 2 are connected by the second latching slots 301 and the second latches 202 engaging with each other.

[0051] When assembling this display panel assembly, the display bottom shell 2 is inserted into the accommodating cavity 102 enclosed by the annular inner panel 101. Because the inner wall of the annular inner panel 101 is provided with multiple first latches 1011, and the outer wall of the display bottom shell 2 is provided with multiple first latches 201 corresponding to the first latches 1011, the display cover 1 and the display bottom shell 2 are connected by the engagement of the first latches 1011 with the first latches 201. Then, the bottom cover 3 is placed on the display bottom shell 2. Because the inner wall of the display bottom shell 2 is provided with multiple second latches 202, and the outer wall of the bottom cover 3 is provided with multiple second latches 301 corresponding to the second latches 202, the bottom cover 3 and the display bottom shell 2 are connected by the engagement of the second latches 202 with the second latches 301, completing the assembly of the display panel assembly.

[0052] The display cover 1 and display bottom case 2 are connected by engaging the first latch 1011 with the first latch slot 201, and the bottom cover 3 and display bottom case 2 are connected by engaging the second latch 202 with the second latch slot 301. This allows for quick connection between the display cover 1 and display bottom case 2, and between the display bottom case 2 and bottom cover 3, without the use of fasteners such as screws. This simplifies the assembly process, making it more convenient and reducing labor costs. This design also avoids problems such as thread stripping or hole breakage caused by the use of fasteners such as screws, thereby improving component reliability and tooling quality.

[0053] Specifically, the shape of the display cover 1 can be set to any existing shape according to needs. The display cover 1 can be made of metal or plastic. In the embodiment of the present application, there is no specific limitation on the structure and material of the display cover 1.

[0054] Specifically, the display bottom shell 2 can be provided in a cylindrical shape, and the bottom cover 3 can be provided in a circular sheet shape. In the embodiment of the present application, the shapes of the display bottom shell 2 and the bottom cover 3 are not specifically limited.

[0055] Specifically, the first snap 1011 and the second snap 202 can be configured as a wedge-shaped protrusion structure, which can make the snaps smoother when inserted into the slots. The first slot 201 and the second slot 301 can be configured as rectangular grooves or through-grooves. In the embodiments of the present application, the structures of the first snap 1011, the second snap 202, the first slot 201, and the second slot 301 are not specifically limited.

[0056] In one embodiment, Figure 5 and Figure 6 As shown, the width of the first slot 201 is adapted to the width of the first buckle 1011 , wherein the first buckle 1011 is provided with a first guide surface 10111 . When one end of the display bottom shell 2 passes over the first guide surface 10111 , the first buckle 1011 can be engaged with the first slot 201 .

[0057] The width of the first slot 201 matches the width of the first latch 1011, allowing them to fit tightly together after being engaged, reducing any gaps and ensuring the overall stability of the display panel assembly. This effectively prevents loosening or shaking between the display cover 1 and the display bottom case 2. Furthermore, the tight fit between the first latch 1011 and the first slot 201 reduces the possibility of external factors such as dust and moisture entering the interior of the display panel assembly, thereby protecting the internal electronic components and extending the service life of the display panel.

[0058] Because the first buckle 1011 is provided with a first guide surface 10111, the first guide surface 10111 serves as a guide when installing the display bottom case 2. When one end of the display bottom case 2 approaches the first buckle 1011, the display bottom case 2 can follow the first guide surface 10111 to smoothly insert the first buckle 1011 into the first slot 201, thereby reducing the difficulty of installing the display bottom case 2. After one end of the display bottom case 2 passes the first guide surface 10111, the first buckle 1011 automatically engages with the first slot 201, ensuring a reliable connection between the display bottom case 2 and the display cover 1.

[0059] Specifically, if Figure 6As shown, the locking surface of the first clip 1011 is arranged opposite to the first guide surface 10111, and the locking surface is perpendicular to the axis of the annular inner panel 101. When the first clip 1011 is engaged with the first slot 201, the locking surface of the first clip 1011 abuts against the inner wall of the first slot 201, ensuring that the display bottom shell 2 and the display cover 1 are firmly fixed to prevent the display bottom shell 2 from falling off from the display cover 1.

[0060] Specifically, if Figure 6 As shown, the first guide surface 10111 is tilted to facilitate the insertion of the first buckle 1011 into the first slot 201. The tilt angle of the first guide surface 10111 can be set to any angle as required. In the embodiment of the present application, the tilt angle of the first guide surface 10111 is not specifically limited.

[0061] In one embodiment, Figure 8 and Figure 9 As shown, the width of the second slot 301 matches the width of the second buckle 202 . The second buckle 202 is provided with a second guide surface 2021 . When the bottom cover 3 passes over the second guide surface 2021 , the second buckle 202 can be engaged with the second slot 301 .

[0062] The width of the second slot 301 matches the width of the second latch 202, ensuring a tight fit between the two after they are engaged, minimizing any gaps and ensuring the overall stability of the bottom cover 3 and the display chassis 2. This effectively prevents loosening or shaking between the bottom cover 3 and the display chassis 2. Furthermore, the tight fit between the second latch 202 and the second slot 301 reduces the possibility of external factors such as dust and moisture entering the interior of the display panel assembly, thereby protecting the internal electronic components and extending the service life of the display panel.

[0063] Because the second clip 202 is provided with a second guide surface 2021, it serves as a guide during installation of the bottom cover 3. When one end of the bottom cover 3 approaches the second clip 202, the bottom cover 3 follows the second guide surface 2021 and smoothly inserts the second clip 202 into the second slot 301, thus simplifying installation of the bottom cover 3. Once the one end of the bottom cover 3 passes the second guide surface 2021, the second clip 202 automatically engages with the second slot 301, ensuring a secure connection between the display base 2 and the bottom cover 3.

[0064] Specifically, the second card slot 301 can be configured to be in the shape of a rectangular notch. In the embodiment of the present application, the shape of the second card slot 301 is not specifically limited.

[0065] Specifically, if Figure 9As shown, the second guide surface 2021 is tilted to facilitate the insertion of the second buckle 202 into the second slot 301. The tilt angle of the second guide surface 2021 can be set to any angle as required. In the embodiment of the present application, the tilt angle of the second guide surface 2021 is not specifically limited.

[0066] In one embodiment, Figure 1 、 Figure 10 and Figure 11 As shown, the display cover 1 further includes an annular outer plate 103, which is disposed outside the annular inner plate 101. The annular inner plate 101 protrudes from the annular outer plate 103 to form a protrusion. A plurality of fourth latches 1021 are provided on the outer wall of the protrusion, and the fourth latches 1021 are used to engage with the housing 5.

[0067] like Figure 3 and Figure 5 As shown, the bottom housing 2 includes a first mounting section 205 and a second mounting section 206, which are coaxially arranged. The first latch 201 is provided on the first mounting section 205, and the second latch 202 is provided on the second mounting section 206. The outer wall of the first mounting section 205 is in contact with the inner wall of the annular inner panel 101, and the diameter of the first mounting section 205 is larger than the diameter of the second mounting section 206.

[0068] Since the annular inner panel 101 protrudes from the annular outer panel 103, and a fourth clip 1021 is provided on the raised portion, the fourth clip 1021 is engaged with the shell 5 of the water heating device, so that the display panel assembly can be firmly fixed on the water heating device, simplifying the connection between the display panel assembly and the shell 5 and facilitating the installation of the display panel assembly on the water heating device.

[0069] The display bottom shell 2 includes a first mounting section 205 and a second mounting section 206 of different diameters. When the display bottom shell 2 is mounted on the display cover 1, the outer wall of the first mounting section 205 fits against the inner wall of the annular inner panel 101, thereby ensuring a tight and seamless connection between the display bottom shell 2 and the display cover 1, thereby improving the overall sealing of the display panel assembly.

[0070] Since the diameter of the first mounting section 205 is larger than the diameter of the second mounting section 206, a spacing is left between the outer wall of the second mounting section 206 and the inner wall of the annular inner panel 101. The position of the spacing corresponds to the position of the fourth clip 1021 on the protrusion. When the protrusion is inserted into the mounting hole 501 of the shell 5, the fourth clip 1021 is squeezed by the edge of the mounting hole 501 and can be deformed in the spacing direction to facilitate the insertion of the protrusion into the mounting hole 501 of the shell 5.

[0071] Specifically, a plurality of fourth buckles 1021 are provided on the outer wall of the raised portion. The plurality of fourth buckles 1021 can be arranged at uniform intervals around the circumference of the raised portion, or can be arranged at non-uniform intervals around the circumference of the raised portion. In the embodiment of the present application, no specific restrictions are imposed on the distribution of the plurality of fourth buckles 1021.

[0072] Specifically, the size of the spacing formed between the second mounting section 206 and the annular inner panel 101 can be adaptively set according to the size of the fourth clip 1021. In the embodiment of the present application, no specific restriction is imposed on the size of the spacing formed between the second mounting section 206 and the annular inner panel 101.

[0073] In one embodiment, Figure 2 As shown, a plurality of opening slots 1031 are provided on the annular inner panel 101 , and an opening slot 1031 is provided on both sides of each fourth buckle 1021 .

[0074] By providing open slots 1031 on both sides of each fourth clip 1021 on the annular inner panel 101, when the display panel assembly is mounted on the water heater housing 5, the presence of the open slots 1031 on both sides of the fourth clip 1021 facilitates elastic deformation of the fourth clip 1021, making it easier for the fourth clip 1021 to snap into the mounting hole 501 of the housing 5, thereby greatly reducing the difficulty of installation. Similarly, when the display panel assembly needs to be disassembled, the open slots 1031 also facilitate the disengagement of the fourth clip 1021, allowing the fourth clip 1021 to be disengaged from the mounting hole 501 of the housing 5, completing the disassembly operation conveniently and quickly.

[0075] The presence of the opening groove 1031 can reduce the stress concentration on the fourth clip 1021 during the clipping process, avoiding damage or breakage of the fourth clip 1021 due to excessive stress during installation, thereby improving the reliability of the connection between the display panel assembly and the water heater housing 5.

[0076] Specifically, the opening groove 1031 can be set in a long strip shape, and the opening grooves 1031 on both sides of the fourth buckle 1021 can be set in parallel. In the embodiment of the present application, there is no specific restriction on the shape and setting method of the opening groove 1031.

[0077] In one embodiment, Figure 2 As shown, the first buckle 1011 and the fourth buckle 1021 are respectively arranged at two ends of the annular inner panel 101 , and the position of the first buckle 1011 and the position of the fourth buckle 1021 are staggered.

[0078] Disposing the first clip 1011 at the end of the annular inner panel 101 away from the fourth clip 1021 can avoid mutual interference between the first clip 1011 and the fourth clip 1021 at the same position, thereby improving the overall structural stability of the display panel assembly.

[0079] Since the first clip 1011 and the fourth clip 1021 are used to connect the display bottom shell 2 and the water heater shell 5 respectively, staggering the first clip 1011 and the fourth clip 1021 can reduce the interference between the first clip 1011 and the fourth clip 1021 during the assembly process, making the assembly smoother.

[0080] In one embodiment, Figure 2 and Figure 3 As shown, a plurality of first buckles 1011 are evenly distributed along the circumference of the annular inner panel 101 , and a plurality of second buckles 202 are evenly distributed along the circumference of the display bottom case 2 .

[0081] By evenly distributing the first clips 1011 along the circumference of the annular inner panel 101, the connection force is evenly distributed across the entire circumference when the display cover 1 is connected to the display bottom case 2. This prevents a weak connection or damage caused by excessive local force, ensuring a stable and reliable connection between the display cover 1 and the display bottom case 2. Similarly, the multiple second clips 202 are evenly distributed along the circumference of the display bottom case 2, ensuring uniform force on the connection between the bottom cover 3 and the display bottom case 2, ensuring consistent connection strength in all directions, and improving the overall stability of the display panel assembly.

[0082] During the assembly process, since the first clips 1011 and the second clips 202 are evenly distributed, the operator can quickly insert the display bottom shell 2 into the accommodating cavity 102 of the annular inner panel 101, or cover the bottom cover 3 on the display bottom shell 2 without the need for complex adjustment and alignment operations, thereby improving assembly accuracy and efficiency.

[0083] In one embodiment, Figure 1 and Figure 7 As shown, the display further includes an electronic control module 4, which includes a wired controller 401 and a communication module 402. The wired controller 401 is mounted within the annular inner panel 101. A mounting plate 203 is provided within the display bottom housing 2, and a plurality of third clips 204 are provided on the mounting plate 203. The outer surface of the communication module 402 is provided with a plurality of third clips 4021 corresponding to the third clips 204.

[0084] The placement of the wired controller 401 within the annular inner panel 101 fully utilizes the internal space of the display cover 1, making the entire display panel assembly more compact. A mounting plate 203 is provided within the display bottom housing 2 and connected to the third slot 4021 of the communication module 402 via a third clip 204. This facilitates installation of the communication module 402 on the mounting plate 203 and improves assembly efficiency. Furthermore, the engagement of the third clip 204 with the third slot 4021 provides a stable fixation for the communication module 402, effectively preventing it from loosening or falling off due to vibration or external forces during use, and ensuring a reliable connection between the communication module 402 and the mounting plate 203.

[0085] Specifically, the communication module 402 can be a WiFi module, a Bluetooth module, etc. In the embodiment of the present application, there is no specific limitation on the type of the communication module 402.

[0086] Specifically, the wired controller 401 can be installed in the display cover 1 by fasteners such as screws. In the embodiment of the present application, there is no specific limitation on the installation method of the wired controller 401.

[0087] Specifically, if Figure 7 As shown, the plurality of third slots 4021 may be distributed on opposite sides of the communication module 402 to ensure that the communication module 402 is firmly fixed on the mounting plate 203 .

[0088] In one embodiment, Figure 7 As shown, there is a distance between the mounting plate 203 and the end of the display bottom housing 2 where the second buckle 202 is provided, and an accommodating cavity 207 is formed. The accommodating cavity 207 is used to accommodate the communication module 402 .
