[0038] In this invention, the terms "comprising," "including," "having," or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0039] In this invention, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. Additionally, in this invention, the character " / " generally indicates that the preceding and following related objects have an "and / or" relationship.

[0040] In this invention, the terms "connection," "combination," "coupling," and "installation" can refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, a direct connection refers to two parts or components being connected together without the need for an intermediary, while an indirect connection refers to two parts or components each being connected to at least one intermediary, with the connection achieved through the intermediary. Furthermore, "connection" and "coupling" are not limited to physical or mechanical connections or couplings, but can also include electrical connections or couplings.

[0041] In this invention, those skilled in the art will understand that relative terms (e.g., “about,” “approximately,” “basically,” etc.) used in conjunction with quantities or conditions are to include the value and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances associated with the particular value due to manufacturing, assembly, use, etc. Such terms should also be considered as disclosing a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​not using relative terms should also be disclosed as specific values ​​with tolerances. Furthermore, “basically” when expressing relative angular relationships (e.g., substantially parallel, substantially perpendicular) may refer to a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) added to or subtracted from the indicated angle.

[0042] In this invention, those skilled in the art will understand that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can be performed by one part, one component, or a combination of multiple parts.

[0043] In this utility model, the directional terms "upper," "lower," "left," "right," "front," and "rear" are used to describe the orientation and positional relationships shown in the accompanying drawings and should not be construed as limiting the embodiments of this utility model. Furthermore, in the context, it should be understood that when one element is mentioned as being connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected through an intermediate element. It should also be understood that directional terms such as upper side, lower side, left side, right side, front side, and rear side not only represent the direct orientation but can also be understood as the lateral orientation. For example, "below" can include directly below, lower left, lower right, lower front, and lower rear.

[0044] Figure 1 A schematic diagram of the display device 1000 provided in this embodiment is shown from one viewing angle. For example... Figure 1 As shown in the figure, this embodiment provides a water heater, which includes a casing (not shown) and a display device 1000. The casing has an installation port, and the display device 1000 is embedded in the installation port. The display device 1000 is used to receive user control input and display character information, so that the user can adjust the status of the water heater and reasonably arrange the bathing time according to the character information.

[0045] It should be noted that the display device 1000 in this embodiment can also be applied to other household appliances (such as washing machines, air conditioners, microwave ovens, etc.) to facilitate users' understanding of the corresponding household appliance's usage information and improve the user experience. Of course, the display device 1000 can not only be installed on the casing of the corresponding household appliance, but also in other locations, as long as it is convenient for the user to observe; this embodiment does not limit this. For ease of description, this embodiment uses the example of the display device 1000 being installed on the casing of a water heater. When those skilled in the art need to install the display device 1000 in other locations on other household appliances, they can make adaptive adjustments to the technical solution of this embodiment.

[0046] Figure 2 A schematic diagram of the display device 1000 provided in this embodiment is shown from another perspective. Figure 3 An exploded view of the display device 1000 provided in this embodiment is shown. Figure 4 An exploded view of the display device 1000 provided in this embodiment from another perspective is shown. Figures 2-4 As shown, the display device 1000 includes a housing 100, a control panel 200, a display bracket 300, and a display panel 400. The housing 100 has an opening 101 on one side. The control panel 200 covers the opening 101 and cooperates with the housing 100 to form a receiving cavity. The display bracket 300 is located in the receiving cavity and is integrally formed on the control panel 200. The display panel 400 is installed in the receiving cavity.

[0047] The display device 1000 provided in this embodiment integrates the display bracket 300 onto the control panel 200. On the one hand, in actual processing, only one set of molds is needed to process the control panel 200 and the display bracket 300 simultaneously, thereby simplifying the processing process and reducing processing costs. On the other hand, the control panel 200 and the display bracket 300 do not need to be assembled, and the use of fasteners when connecting the two can be saved, further reducing processing costs and improving the assembly efficiency of the entire display device 1000.

[0048] In this embodiment, both the control panel 200 and the display bracket 300 are made of plastic, which is lightweight, safe, corrosion-resistant, and easy to clean. Furthermore, both the control panel 200 and the display bracket 300 are molded using injection molding, resulting in high production efficiency, low production costs, and good environmental performance.

[0049] Figure 5 A schematic diagram of the control panel 200 and display bracket 300 provided in this embodiment is shown. Figure 6 It shows Figure 5 A magnified view of a portion at point A. (See attached image.) Figures 5-6 and combined Figure 4 As shown, the display bracket 300 is provided with a snap-fit ​​member 301, and the display panel 400 is provided with a snap-fit ​​hole 401 that engages with the snap-fit ​​member 301. By providing the snap-fit ​​member 301 and the snap-fit ​​hole 401, a stable connection can be achieved between the display bracket 300 and the display panel 400, and operation is convenient. Of course, in other embodiments, the snap-fit ​​hole 401 can also be provided on the display bracket 300, and the snap-fit ​​member 301 can be provided on the display panel 400, achieving the same effect.

[0050] Optionally, the number of snap-fit ​​pieces 301 is at least two, and the at least two snap-fit ​​pieces 301 are arranged at intervals along the circumference of the display bracket 300. Each snap-fit ​​piece 301 corresponds to a snap-fit ​​hole 401 to further ensure the stability of the connection between the display bracket 300 and the display panel 400. In this embodiment, the number of snap-fit ​​pieces 301 is two, and the two snap-fit ​​pieces 301 are symmetrically arranged on both sides of the display bracket 300. While ensuring a stable connection between the display bracket 300 and the display panel 400, the number of snap-fit ​​pieces 301 is reduced to lower the processing cost. Of course, in other embodiments, the number of snap-fit ​​pieces 301 can also be three, four, five, six, or even more, and is not limited here.

[0051] Specifically, the snap-fit ​​component 301 includes a connecting portion 3011 and a hook portion 3012 connected together. One end of the connecting portion 3011 is connected to the display bracket 300, and the hook portion 3012 can pass through the snap-fit ​​hole 401 and snap onto the side of the display panel 400 opposite to the display bracket 300. The structure is simple and easy to process. Optionally, the snap-fit ​​component 301 is made of an elastic material. With this arrangement, on the one hand, during assembly, the snap-fit ​​component 301 can deform under the pressure of the snap-fit ​​hole 401, so that the snap-fit ​​component 301 can be smoothly snapped into the snap-fit ​​hole 401; on the other hand, after assembly is completed, the snap-fit ​​component 301 can also be tightly snapped into the snap-fit ​​hole 401 under its own elastic force, further ensuring the stability of the connection between the display bracket 300 and the display panel 400. In this embodiment, the snap-fit ​​component 301 is a plastic part, which is integrally formed on the display bracket 300 to simplify the processing technology and ensure a stable connection between the snap-fit ​​component 301 and the display bracket 300.

[0052] Optionally, a guide slope 30121 is provided on the side of the hook portion 3012 away from the connecting portion 3011 to provide guidance for the insertion of the snap-fit ​​member 301 into the snap-fit ​​hole 401. Specifically, in this embodiment, there are two snap-fit ​​members 301, which are symmetrically arranged on opposite sides of the display bracket 300. The guide slope 30121 is provided on the side of the two snap-fit ​​members 301 that is away from each other, and the guide slope 30121 gradually slopes outward along the side closer to the display bracket 300. During assembly, the two snap-fit ​​members 301 are inserted into the corresponding snap-fit ​​hole 401. Under the squeezing action of the snap-fit ​​hole 401, the two snap-fit ​​members 301 deform in the direction that they move closer to each other. After the hook portion 3012 passes through the corresponding snap-fit ​​hole 401, the snap-fit ​​member 301 can reset itself under the action of its own elastic restoring force, thereby tightly snapping onto the side of the display panel 400 away from the display bracket 300.

[0053] like Figure 4 and Figure 5 As shown, in this embodiment, the control panel 200 is provided with a positioning member 201, and the display panel 400 is provided with a positioning hole 402 that engages with the positioning member 201. By providing the engaging positioning member 201 and the positioning hole 402, accurate positioning of the control panel 200 and the display panel 400 can be achieved, improving the installation accuracy between them. Of course, in other embodiments, the positioning member 201 can also be provided on the display panel 400, and the positioning hole 402 can be provided on the control panel 200, achieving the same effect.

[0054] Optionally, in this embodiment, there are two positioning elements 201, which are respectively located at two opposite corners of the control panel 200. Each positioning element 201 corresponds to a positioning hole 402. This avoids the display panel 400 from rotating around the axis of the positioning element 201 when only one positioning element 201 is used, thus preventing the positioning effect from being affected. Of course, this embodiment does not limit the number or arrangement of the positioning elements 201. Designers can adjust the number and arrangement of the positioning elements 201 according to actual assembly requirements.

[0055] It is understandable that, such as Figure 4As shown, the display bracket 300 protrudes from one side of the control panel 200. When the display bracket 300 is connected to the display panel 400, the display panel 400 is essentially suspended in the receiving cavity. The snap-fit ​​member 301 and the positioning member 201 bear all the weight of the display panel 400, and the uneven stress makes them prone to breakage. To solve this problem, in this embodiment, a surrounding plate 202 is also provided on the side of the control panel 200 facing the housing 100. The surrounding plate 202 surrounds the display bracket 300, and the display panel 400 is inserted into the mounting groove formed by the surrounding plate 202. By providing the surrounding plate 202, the display panel 400 can be supported, preventing the snap-fit ​​member 301 and the positioning member 201 from breaking due to excessive stress after prolonged use. The positioning member 201 is located within the mounting groove formed by the surrounding plate 202.

[0056] like Figure 2 and Figure 4 As shown, the housing 100 and the control panel 200 are fixed together by a connector to ensure the stability of the connection between them. Specifically, the housing 100 has a first connecting hole 102, the display panel 400 has a second connecting hole 403 corresponding to the first connecting hole 102, and the control panel 200 has a third connecting hole 204 corresponding to the first connecting hole 102. The connector passes through the first connecting hole 102 and the second connecting hole 403 in sequence and is then screwed into the third connecting hole 204, thereby connecting the housing 100, the control panel 200, and the display panel 400. The connector is a bolt, the third connecting hole 204 is a threaded hole, and the first connecting hole 102 and the second connecting hole 403 are through holes. Bolt connections offer the advantages of secure connection and easy assembly / disassembly.

[0057] To achieve accurate positioning and installation between the housing 100 and the control panel 200, in this embodiment, a slot 203 is provided on the side of the control panel 200 facing the housing 100, and the edge of the opening 101 of the housing 100 is inserted into the slot 203. When assembling the housing 100 and the control panel 200, the edge of the opening 101 of the housing 100 can be aligned with the slot 203 and inserted. At this time, the first connecting hole 102, the third connecting hole 204, and the second connecting hole 403 of the housing 100 are all aligned, and the connector can be smoothly inserted into the first connecting hole 102, the second connecting hole 403, and the third connecting hole 204, resulting in accurate positioning and convenient operation.

[0058] Optionally, in this embodiment, a positioning plate 205 protrudes from the side of the control panel 200 facing the housing 100. The positioning plate 205 and the surrounding plate 202 are spaced apart, and the gap between them forms the aforementioned slot 203. This arrangement avoids the control panel 200 from being too thin, which would affect its structural strength, if the slot 203 were directly opened on the control panel 200.

[0059] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that the above embodiments do not limit this utility model in any way, and all technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of this utility model.
