[0035] The terms and words used in the following description and claims are not limited to the literal meanings, but are merely used by the inventor to enable a clear and consistent understanding of the present disclosure. Therefore, it should be clear to those skilled in the art that the following description of various embodiments of the present disclosure is provided for illustration only and is not intended to limit the present disclosure as defined by the appended claims and their equivalents.

[0036] The terms "having", "may have", "include", or "may include" used in various embodiments of the present disclosure indicate the presence of the corresponding functions, operations, elements, etc. disclosed, but do not limit the additional one or more functions, operations, elements, etc. In addition, it should be understood that the terms "including" or "having" used in various embodiments of the present disclosure are intended to indicate the presence of the features, numbers, operations, elements, components, or combinations thereof described in the specification, but do not exclude the presence or addition of one or more other features, numbers, operations, elements, components, or combinations thereof.

[0037] It will be understood that when an element (for example, a first element) is “connected” to another element (for example, a second element), the element can be directly connected to the other element or an intervening element (for example, a third element) may be present between the element and the other element.

[0038] An embodiment of the present invention provides a display adapted to a curved panel, such as Figure 1-3As shown, the display 100 includes a frame 110, a soft pad 120, and a display film 130. A plurality of light-emitting devices 111 are fixed to the front side of the frame 110. The light-emitting devices 111 are distributed according to preset positions so that they can emit light at specific positions, so that the entire display can ultimately display preset text, numbers, letters, and / or patterns. The light-emitting devices 111 can specifically be light-emitting diodes. The soft pad 120 is fixed to the front side of the frame 110, and is provided with a plurality of light-transmitting holes 121 that pass through it and correspond to the light-emitting devices 111. Specifically, the number and position of the light-emitting devices 111 correspond to the number and position of the light-transmitting holes 121. The light-emitting devices 111 are located in their corresponding light-transmitting holes 121, and the light emitted by the light-emitting devices 111 is emitted from the light-transmitting holes 121. At the same time, the light-transmitting holes 121 can also play a role in confining light, so that the illumination range of the light is not too large, so as not to affect the light emission of other light-emitting devices 111. The cushion 120 can be made of soft materials such as plastic and rubber, so that the cushion 120 can be deformed. The display film 130 is fixed to the front side of the cushion 120, and a plurality of display areas 131 corresponding to the light-transmitting holes 121 are provided on the display film 130. Specifically, the number and position of the display areas 131 correspond to the number and position of the light-transmitting holes 121, respectively. The display areas 131 are transparent to light, and other areas of the display film 130 except the display areas 131 are not transparent to light. The display area 131 forms any one or more of preset text, numbers, letters and patterns for displaying information such as menus, time, and temperature. When a light-emitting device 111 emits light, its corresponding display area 131 is illuminated by the light emitted by the light-emitting device 111 to convey corresponding information to the user.

[0039] In this embodiment, a soft pad 120 is provided between the frame 110 and the display film 130. The soft pad 120 can be deformed according to the shape of the panel, and the display film 130 can also be deformed according to the soft pad 120, so that the display film 130 can be tightly attached to the panel. This ensures that there is no gap between the entire display 100 and the panel, and cross-light and reflection phenomena are not easily generated on the panel, which effectively improves the display effect of the display.

[0040] In some embodiments, as Figure 3 As shown, in a direction perpendicular to the cushion 120 and pointing to the front side of the cushion 120, the diameter of at least a portion of the light-transmitting holes 121 gradually increases, so that the cross-section of this portion of the light-transmitting holes 121 can be shaped like a trumpet. The light-transmitting holes 121 with this structure can play a light-guiding role for the light emitted by the light-emitting device.

[0041] In some embodiments, the cushion 120 is attached to the front side of the frame 110 using adhesive, allowing the cushion 120 to fit more closely to the frame 110 and providing a more secure connection. The display film 130 is also attached to the front side of the cushion 120 using adhesive, allowing the display film 130 to deform more synchronously with the cushion 120 to adhere more closely to the panel.

[0042] An embodiment of the present invention provides a display component, such as Figure 4 As shown, a display adapted for curved panels includes a circuit board 300 and any of the above-described embodiments. The specific structure of the display adapted for curved panels can be referenced in the above-described embodiments and will not be further described here. The display frame 110 is fixed to the circuit board 300. A driving circuit electrically connected to the light-emitting device can be provided on the circuit board 300 to drive the light-emitting device to emit light when the circuit board 300 is powered.

[0043] The embodiment of the present invention also provides another display component, such as Figure 5 and Figure 6 As shown, the display assembly further includes a plurality of lamp beads 310, a bracket 400, and a plurality of lamp caps 500 corresponding to the lamp beads 310. Specifically, the number and position of the lamp caps 500 may correspond to the number and position of the lamp beads 310. The lamp beads 310 and bracket 400 are both fixed to a circuit board 300. The circuit board 300 may be provided with a driving circuit electrically connected to the lamp beads 310. When the circuit board 300 is connected to a power source, the circuit board 300 can drive the lamp beads 310 to emit light. The bracket 400 is provided with a plurality of through-holes 401 corresponding to the lamp beads 310. Specifically, the number and position of the through-holes 401 may correspond to the number and position of the lamp beads 310, so that light emitted by the lamp beads 310 can pass through the corresponding through-holes 401. The lamp caps 500 are disposed in the through-holes 401 and are movable along the axial direction of the through-holes 401. An elastic member 320 is also disposed within the through-holes 401, with one end of the elastic member 320 abutting the lamp cap 500 and the other end abutting the circuit board 300. The elastic member 320 can apply a thrust to the lamp cap 500, causing the lamp cap 500 to extend outward, so that the lamp cap 500 can be tightly attached to the panel in front of it. There is no gap between the lamp cap 500 and the panel, and light crosstalk and reflection are not likely to occur on the panel, which improves the display effect of the light.

[0044] In this embodiment, the elastic member 320 can be a spring, and the lamp bead 310 is located inside the spring so that the spring does not block the light of the lamp bead 310. Of course, according to actual needs, it can also be other objects that can generate elastic thrust, such as shrapnel.

[0045] All lamp caps 500 may have a uniform shape and size for ease of manufacture and assembly. Of course, for different display effects, the lamp caps 500 may have a variety of shapes and sizes. Figure 5 and Figure 6 As shown, the main body of part of the lamp cap 500 can be cylindrical, and the shape of the other part of the lamp cap 500 can be square cylindrical. In order to enable the lamp cap 500 to move smoothly in the through hole 401, the shape and size of the through hole 401 naturally need to be adapted to the shape and size of the lamp cap 500.

[0046] In some embodiments, as Figure 6 and Figure 7 shown, a protruding limiting member 402 is provided on the inner wall of the end of the through hole 401 away from the circuit board 300. The limiting member 402 can surround the inner wall of the through hole 401 for one week, or a plurality of them can be discretely distributed on the inner wall of the through hole 401. The presence of the limiting member 402 is equivalent to reducing the diameter of the opening of the end of the through hole 401 away from the circuit board 300. A protruding blocking member 501 is provided on the circumferential surface of the lamp cap 500. The blocking member 501 can surround the circumferential surface of the lamp cap 500 for one week, or a plurality of them can be discretely distributed on the circumferential surface of the lamp cap 500. When the lamp cap 500 moves in the direction away from the circuit board 300 under the thrust of the elastic member 320, the limiting member 402 can abut against the blocking member 501, and the lamp cap 500 will be stuck and unable to continue moving in the original direction, which can limit the lamp cap 500 from disengaging from the through hole 401 and prevent the lamp cap 500 from falling.

[0047] In some embodiments, guide bars 403 extending along the axial direction of the through hole 401 are provided on the inner wall of at least a part of the through holes 401. Guide grooves 502 adapted to the guide bars 403 are provided on the lamp cap 500 located in the through holes 401 provided with the guide bars 403. The guide bars 403 and their adapted guide grooves 502 are slidably配合 along the axial direction of the through hole 401, that is, when the lamp cap 500 moves along the axial direction of the through hole 401, the guide bars 403 can slide in the guide grooves 502, which plays a guiding role in the movement of the lamp cap 500 and enables the lamp cap 500 to maintain sliding along the axial direction of the through hole 401.

[0048] Furthermore, the guide grooves 502 can specifically be provided on the blocking member 501 in the above embodiments.

[0049] In some embodiments, as Figure 6 and Figure 8 shown, the lamp cap 500 includes a cap cylinder 510 and a cap 520. The cap cylinder 510 can be cylindrical or square cylindrical. The cap 520 is provided at one end of the cap cylinder 510 and is connected to the cap cylinder 510, and the cap 520 seals the opening at one end of the cap cylinder 510, so that the cross-sectional shape of the lamp cap 500 is similar to a "凵" shape. The lamp beads 310 are provided at the end of the cap cylinder 510 away from the cap 520, and the light emitted by the lamp beads 310 is refracted by the cap 520 and then emitted outward.

[0050] In this embodiment, the inner side surface of the cap 520 (i.e., the side close to the circuit board 300) is set to be a convex surface, that is, the middle part of the inner side surface of the cap 520 protrudes outward, and the thickness of the cap 520 gradually decreases from the center position in the radial outward direction, which can scatter the light, making the light more uniform and further improving the lighting effect.

[0051] In some embodiments, the outer side surface of the cap 520 is in an arc shape that matches the panel, so that the lamp cap is more closely attached to the panel under the action of the elastic member 320, and reflection is less likely to occur on the panel, which improves the display effect of the display on the panel.

[0052] In some embodiments, as Figure 6 and Figure 7 As shown, the bracket 400 is provided with a plurality of first clips 410, and the circuit board 300 is provided with a plurality of first buckle holes 301 that match the first clips 410. Specifically, the number and position of the first buckle holes 301 correspond to the number and position of the first clips 410, so that each first clip 410 is snapped into its corresponding first buckle hole 301. This embodiment uses a snap connection method to fix the bracket 400, which is simple to operate and facilitates installation and removal of the bracket 400.

[0053] Furthermore, the bracket 400 is provided with a plurality of first mounting holes 404, and the circuit board 300 is provided with a plurality of second mounting holes corresponding to the first mounting holes 404. Specifically, the corresponding first mounting holes 404 and second mounting holes may be coaxially arranged. Connectors are inserted through the first mounting holes 404 and the corresponding second mounting holes. The connectors secure the bracket 400 to the circuit board 300, thereby enhancing the stability of the bracket 400 fixed to the circuit board 300.

[0054] The connecting piece may be a screw or a bolt.

[0055] An embodiment of the present invention further provides a display component, such as Figure 9 As shown, compared with the above embodiment, the display assembly of this embodiment further includes a display box 200. The display box 200 has a box-like structure with an open front side. The circuit board 300 is fixed in the display box 200. The display box 200 can protect the circuit board 300 and other components. The display box 200 also facilitates fixing the entire display assembly to the water heater.

[0056] The embodiment of the present invention further provides a water heater, such as Figure 10 and Figure 11 As shown, it includes a front shell 600, a panel 700 fixed to the front side of the front shell 600, and a display component of any of the above-mentioned embodiments fixed to the front shell 600. For specific instructions on the display component, please refer to the above-mentioned embodiments and will not be repeated here.

[0057] In this embodiment, the panel 700 has an outwardly convex curved surface, and the display film is closely attached to the back side of the panel 700. Specifically, the spacing between the frame of the mounted display and the panel 700 is set to be less than or equal to the sum of the thicknesses of the cushion and the display film. This allows the cushion and display film to deform, keeping the display film tightly attached to the panel 700. This eliminates any gap between the display and the panel 700, reduces cross-lighting and reflections on the panel 700, and effectively improves the display quality.

[0058] The lamp cap 500 in the above embodiment can also abut the back side of the panel 700 (the side close to the front shell 600) under the action of the elastic member. Therefore, there is no gap between the lamp cap 500 and the panel 700, and light crosstalk and reflection are not likely to occur on the panel 700, which improves the display effect of the light.

[0059] It should be noted that Figure 10 and Figure 11 Only the structures of the front shell 600, the panel 700 and the display assembly of the water heater are illustrated. Other structures of the water heater can adopt conventional structural designs in the art.

[0060] In some embodiments, an opening 610 is provided on the front shell 600, and the display assembly is fixed at the opening, which can avoid the problem of insufficient installation space between the front shell 600 and the panel 700 when the display assembly is fixed to the front side of the front shell 600.

[0061] Furthermore, the inner wall of the opening 610 is provided with a plurality of flanges 611, and the display box 200 can be fixedly connected to the flanges 611 and can cover the opening 610. Specifically, a plurality of second buckles 210 can be provided on the circumference of the display box 200, and a plurality of second buckle holes 612 that match the second buckles 210 can be provided on the flanges 611. The second buckles 210 are snapped into the second buckle holes 612 to securely connect the display box 200 to the flanges 611.

[0062] The above is a further detailed description of the present invention in conjunction with specific embodiments, and the specific implementation of the present invention cannot be considered to be limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention.
