Description

Technical Field

[0001] The utility model belongs to the technical field of household appliances, and in particular relates to a glue-spraying structure of a screen display component, a supporting plate and a gas water heater. Background Art

[0002] A gas water heater, also known as a gas water boiler, is a gas appliance that uses gas as fuel and transfers heat to cold water flowing through a heat exchanger through combustion heating to achieve the purpose of preparing hot water.

[0003] After sufficient market research, it is found that gas water heaters with large-screen appearance display structures are more popular with consumers. For the control structure of the large screen, a larger support plate is required. The screen is usually connected to the support plate by gluing, but there is no need to simultaneously expand the gluing area to avoid increasing the complexity of the gluing operation and unnecessary waste of glue. Therefore, for the large-screen display, the gluing structure of the support plate needs to be redesigned. Utility Model Content

[0004] In order to solve the above technical problems, the present application further improves the existing glue structure on the screen support, so as to adapt to the gluing of large-screen display parts without increasing the gluing operation steps and wasting glue. One of the purposes of the present utility model is to provide a glue structure for a screen display part, the second purpose is to provide a corresponding support plate, and the third purpose is to provide a corresponding gas water heater.

[0005] The specific technical solutions are described below:

[0006] The glue structure of the screen display is located on the glue side of the support plate and is used to glue the display. The glue structure includes:

[0007] A plurality of connecting surfaces, used to provide a basis for connecting the display element;

[0008] An anti-overflow glue spacer is provided relative to the connection surface protrusion, and is used to prevent the overflow of glue. The anti-overflow glue spacer is provided separately in each of the connection surfaces, and divides the connection surface into a glue application area and an edge area, wherein the glue application area and the edge area are sequentially distributed in a radial direction pointing to the outer edge of the support plate;

[0009] The glue guiding groove is adjacently arranged on one side of the glue application area close to the middle of the support plate and is used for guiding outflowing glue.

[0010] In the above technical solution, the gluing of the large-screen display components can be achieved only through the gluing area, which can not only achieve the gluing of the large-screen display components, but also will not increase the gluing steps and will not waste glue. At the same time, the anti-overflow glue interval can also prevent glue overflow. Even if there is overflow, it will be guided out from the glue guide groove adjacent to the gluing area.

[0011] Preferably, a plurality of the connecting surfaces are spaced apart and evenly distributed on the periphery of the gluing side. The evenly arranged connecting surfaces can ensure the even distribution of the gluing area and the even distribution of the bonding strength. Other functional components can be arranged at the intervals between the gluing surfaces.

[0012] Preferably, the protrusion height of the anti-overflow glue interval relative to the connection surface is 0.15-0.25 mm. If it is too high, it will occupy a large space, and if it is too low, the ability to prevent glue overflow will be low.

[0013] Preferably, the outer contour of the edge area is a rounded corner and two edges extending along both sides of the rounded corner. The straight lines on which the two edges are located are perpendicular to each other, forming the same shape as the rounded rectangular part. Compared with the commonly used super ellipse, the corresponding area is larger, which is particularly suitable for large-screen displays and provides sufficient space for the setting of anti-overflow glue intervals.

[0014] Preferably, the outer contour of the notch of the glue guiding groove is matched with the inner contour of the glue application area to form a compact overflow glue outlet structure.

[0015] Preferably, in order to further enhance the adhesive strength, a reinforcement portion is provided between two adjacent connection surfaces, and a plurality of adhesive reinforcement grooves are provided on the reinforcement portion. The adhesive reinforcement grooves can increase the contact area of ​​the adhesive, thereby enhancing the adhesive strength.

[0016] Preferably, the glue guiding groove is arranged adjacent to the reinforcing portion on one side close to the middle of the supporting plate, and is used for guiding overflowing glue.

[0017] Preferably, two ends of the anti-overflow glue spacer are arranged at the outer contour of the glue guiding groove to form an anti-overflow glue range that is wrapped inwardly.

[0018] The support plate has an outer contour of a rounded rectangle and includes the gluing structure described in any of the above technical solutions.

[0019] A gas water heater comprises a support plate with a glued display component, wherein the support plate comprises the glue-applying structure described in any one of the above technical solutions.

[0020] In summary, the technical solution described in the utility model has the following main beneficial effects:

[0021] Compared with the prior art, the technical solution of the utility model can realize the gluing of large-screen display components without increasing the gluing steps and wasting glue; at the same time, it can also prevent glue overflow and guide the overflowed glue from the glue guide groove adjacent to the gluing area.

[0022] At the same time, the bonding strength can be further enhanced through the bonding reinforcement groove on the reinforcement part.

[0023] Further or more detailed beneficial effects will be described in detail in conjunction with specific examples in the specific implementation manner. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The present invention is further explained with reference to the following embodiments:

[0032] The core technical problem faced by the technical solution of the embodiment of the present application comes from the inventor's accurate understanding of the prior art. Therefore, how to adapt the gluing of large-screen display components without increasing the gluing steps and wasting glue is a technical problem that the inventor urgently needs to solve.

[0033] At the same time, how to further enhance the bonding strength is also a technical problem that the inventors want to solve simultaneously.

[0034] It should be noted that the embodiments do not constitute a limitation on the protection scope of the claims of the utility model. According to the technical concepts provided / proven by the embodiments, all technical solutions that can be reasonably anticipated by technical personnel in the relevant technical field should be included in the protection scope of the claims of the utility model.

[0035] The embodiments are described in detail as follows:

[0036] Example:

[0037] This embodiment is derived from the display and control structure on the gas water heater housing assembly d. The structure can be referred to in the attached Figure 4 , including a keypad back panel b, a keypad c, a cover d, a support plate e and a display component f which are assembled with each other, wherein the display component f is a whole piece of glass.

[0038] The technical solution of this embodiment relates to the gluing structure on one side of the support plate e glued to the display element f of the larger screen.

[0039] Reference Figures 1-2 The gluing structure is arranged on the gluing side of the support plate e. In this embodiment, the outer contour of the support plate e is a rounded rectangle. Specifically, the gluing structure includes four connecting surfaces e-1 for providing connection to the large-screen glass. The four connecting surfaces e-1 are spaced and evenly distributed at the four corners of the support plate e.

[0040] Each connection surface e-1 is provided with an anti-overflow glue spacer e-2 for preventing glue from overflowing. The protrusion height of the anti-overflow glue spacer e-2 relative to the connection surface e-1 is 0.20 mm, and the height is usually 0.15 to 0.25 mm. If it is too high, it will occupy a large space, and if it is too low, the ability to prevent glue from overflowing is low.

[0041] The anti-overflow glue spacer e-2 separates the connecting surface e-1 into a gluing area e-1.1 and an edge area e-1.2, wherein the gluing area e-1.1 and the edge area e-1.2 are sequentially distributed in the radial direction pointing to the outer edge of the support plate e, that is, the gluing area e-1.1 is closer to the middle of the support plate e than the edge area e-1.2.

[0042] A glue guide groove e-3 is provided adjacent to the inner side of the glue application area e-1.1, and the glue guide groove e-3 is used to guide out the overflowed glue.

[0044] Moreover, the outer contour of the edge region e-1.2 is a rounded corner and two mutually perpendicular sides extending along the two sides of the rounded corner, which constitute a partial shape of the rounded rectangle. Compared with the commonly used superelliptical shape, the rounded rectangle has a larger area, is particularly suitable for connection with a large-screen display f, and provides sufficient space for setting the anti-overflow glue spacer e-2;

[0045] Furthermore, the uniform setting of the connection surface e-1 can ensure the uniform distribution of the gluing area e-1.1, so that the bonding strength is evenly distributed.

[0048] The embodiment further provides a support plate e, and the glue-coated side of the support plate e uses the glue-coated structure described in any of the technical solutions of the above embodiments to adapt to the assembly of the large-screen display element f.

[0049] The embodiment also provides a gas water heater, wherein a display and control structure is provided on the face shell component d of the gas water heater, as shown in the attached Figure 4 As shown, the display and control structure includes a keypad back panel b, a keypad c, a surface shell d, a support plate e and a display component f that are assembled with each other.
