[0067] 200 Home Appliances Detailed Implementation

[0068] To make the technical problem to be solved, the technical solution, and the beneficial technical effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and several exemplary embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the scope of protection of the present utility model. It should be noted that the directional terms used in the description refer to the conventional use of household appliances for ease of description and should not be construed as absolute limitations on the corresponding features.

[0069] Figure 1 A household appliance 200 according to one embodiment of the present invention is illustrated schematically. Figure 1 As shown, the household appliance 200 has a display module 3. Furthermore, in Figure 1 In the embodiment shown, the display module 3 is integrated into the control module 1. Figure 1 (Schematably outlined with a dashed box in the image), the control module 1 is integrated into the display panel 100. The display panel 100, control module 1, and display module 3 all have a user-facing front surface and are integrated into the user-facing front surface of the home appliance 200. Each front surface extends substantially along a first direction parallel to the ground and a second direction perpendicular to the ground. The front surface can be a curved surface with a certain curvature and / or an inclined surface with a certain degree of inclination. The embodiments of this utility model are not limited to... Figure 1 As shown, for example, the home appliance 200 may only have the display module 3 without the control module 1 and / or the display panel 100. In other words, the display module 3 may be an independent display module without being integrated with other modules or may be integrated separately into the display panel 100. Alternatively, the control module 1 with the display module 3 may be integrated into the home appliance 200 as an independent module without being integrated into the display panel.

[0070] Figure 2 The diagram schematically shows a front view of a display module 3 for a household appliance 200 according to an embodiment of the present invention, specifically a front view of its decorative component 30. Figure 3 An exploded view schematically illustrates a control module 1 with a display module 3 according to an embodiment of the present invention, specifically an exploded view of the display module 3 integrated into the control module 1. Figure 2 and Figure 3As shown, the display module 3 includes: a light-emitting element 31; and a decorative component 30, which has a display area 301 configured to be suitable for displaying light effects and preferably in a generally elongated shape, and a non-display area 302 adjacent to the display area 301. The display module 3 is configured to cause the light emitted by the light-emitting element 31 to produce a light effect with a predetermined change in light intensity, such that in a first state of the household appliance 200, the light-emitting element 31 does not emit light and the display area 301 has a first display effect different from the non-display area 302; in a second state of the household appliance 200 different from the first state, the light-emitting element 31 emits light, causing the display area 301 to display a second display effect including a light effect with a predetermined change in light intensity. Note that the shape of the display area 301 is not limited to a generally elongated shape; in other optional embodiments, the display area 301 can also be designed with other suitable shapes as needed. Furthermore, in other optional embodiments, in the first state of the household appliance 200 where the light-emitting element 31 does not emit light, the display area 301 can also have the same display effect as the non-display area 302.

[0071] In a preferred embodiment, the first display effect may include a first preset color, the non-display area 302 may have a second preset color, and the predetermined light intensity variation of the second display effect may be a light-emitting strip with a third preset color. In this way, different display effects can be obtained using the display module 3 in different states of the household appliance 200.

[0072] In a preferred embodiment, the first state is the off state of the home appliance 200, and the second state is the on state of the home appliance 200. This allows for different display effects to be obtained through the display module 3 when the home appliance 200 is on and off, thereby enhancing the user's interactive experience. Of course, the first and second states can also correspond to other different states of the home appliance 200 as needed.

[0073] In a preferred embodiment, the first preset color is the same as or similar to the third preset color. In a preferred example, both the first and third preset colors are blue-green, corresponding to a visible light wavelength of 495nm. The second preset color can be the same as or match the main color of the household appliance 200, such as black. In other optional embodiments, the first preset color can also be the same as or similar to the second preset color, such as both being black, so that in the first state where the light-emitting element 31 is not emitting light, the display area 301 has the same display effect as the non-display area 302.

[0074] In a preferred embodiment, the light emitted by the light-emitting element 31 has the third preset color.

[0075] In a preferred embodiment, the predetermined light intensity change is such that the light intensity gradually weakens along the length extension direction of the light-emitting strip, that is, along the length extension direction of the display area 301.

[0076] To achieve one or more of the effects described in the above embodiments, in a preferred embodiment, the decorative component 30 includes: a light guide 32 for guiding light from the light-emitting element 31; a light-shielding layer 33 having a light-transmitting pattern area 331 corresponding to the display area 301 that transmits light from the light guide 32 and a light-shielding area corresponding to the non-display area 302; and a decorative layer 34 including a non-transparent decorative area 342 covered by non-transparent decorative ink corresponding to the non-display area 302 and a light-transmitting decorative area 341 covered by light-transmitting decorative ink corresponding to the display area 301, wherein the light-transmitting decorative area 341 is configured to block the light-transmitting pattern area 331 of the light-shielding layer 33 when the light-emitting element 31 is not emitting light. In the light effect area of ​​the display area 301 corresponding to a predetermined light intensity change, the light-transmitting decorative ink of the light-transmitting decorative area 341 has the aforementioned first preset color. Furthermore, the non-transparent decorative ink of the non-transparent decorative area 342 has a second preset color. With the above-described configuration of the decorative component 30, when the light-emitting element 31 is not emitting light, the display area 301 can display only the light-transmitting decorative area 341 of the decorative layer 34, thus achieving a first display effect; while when the light-emitting element 31 emits light, the display area 301 can obtain a second display effect, including a predetermined light intensity variation, by transmitting light originating from the light-emitting element 31 and passing through the light guide 32 and the light-shielding layer 33's light-transmitting pattern area 331. In other optional embodiments, the decorative component 30 may also exclude the light-shielding layer 33, as described below.

[0077] Alternatively, it may not have a light-transmitting decorative area 341 covered with light-transmitting decorative ink corresponding to the display area 301. In this case, when the light-emitting element 31 does not emit light, the display area 301 cannot display the first display effect, but is consistent with the non-display area 302.

[0078] To achieve the luminous effect of the predetermined light intensity change, in a preferred embodiment, such as... Figure 3 As shown, the display module 3 includes a plurality of light-emitting elements 31 uniformly arranged in a strip shape, for example, seven identical light-emitting elements 31, and the light-transmitting pattern area 331 of the light-shielding layer 33 has a transparency that gradually decreases along the strip arrangement direction of the light-emitting elements 31. In this way, the light from the uniformly arranged light-emitting elements 31 has a light effect where the light intensity gradually weakens along the light-emitting strip after passing through the light-transmitting pattern area 331, and then the gradually weakening light effect is displayed through the light-transmitting decorative area 341.

[0079] In another preferred embodiment, such as Figure 4AAs shown, the display module 3 includes a single light-emitting element 31 or multiple light-emitting elements 31 arranged together, and the light guide 32 includes a long strip of light guide, one end of which is arranged adjacent to the light-emitting element 31, and the light guide efficiency gradually decreases as it moves away from the light-emitting element 31. Thus, light from the light-emitting element 31 at one end of the light guide 32 has a light effect where the light intensity gradually weakens along the light-emitting strip. In this embodiment, the decorative component 30 may or may not include the light-shielding layer 33.

[0080] In another preferred embodiment, the display module 3 includes a plurality of light-emitting elements 31 arranged in a strip shape with a gradually decreasing density along the strip's direction. This allows for a gradual decrease in light intensity along the light-emitting strip through the gradually decreasing density arrangement of the multiple light-emitting elements 31. Such a density-decreasing arrangement includes at least two methods, one of which is as follows: Figure 4B As shown, the spacing between multiple light-emitting elements 31 arranged in a single row gradually increases along the direction of the strip arrangement; another type is as follows... Figure 4C As shown, there are multiple rows of light-emitting elements 31 along the long strip arrangement direction, and the number of light-emitting elements 31 in each row gradually decreases along the long strip arrangement direction.

[0081] In yet another preferred embodiment, the plurality of light-emitting elements 31 can be as follows: Figure 3 As shown, the light-emitting elements 31 are arranged uniformly along the long strip direction. However, the brightness of the multiple light-emitting elements 31 gradually decreases along the long strip direction, thereby obtaining a light effect in which the light intensity gradually weakens along the light-emitting strip.

[0082] Similarly, in these preferred embodiments, the decorative component 30 may or may not include the light-shielding layer 33.

[0083] Furthermore, in the above-described preferred embodiments with the light-shielding layer 33, the light-transmitting pattern area 331 of the light-shielding layer 33 may be printed with textures or patterns that correspond to the light effect of a predetermined light intensity change, or may be independent textures or patterns unrelated to the light intensity change.

[0084] In addition, the light-transmitting decorative area 341 of the decorative layer 34 may also be printed with textures or patterns corresponding to the light effect of the predetermined light intensity change, or independent textures or patterns, so as to achieve a specific light effect alone or together with the light-transmitting pattern area 331 of the light-emitting element in the state of emitting light and / or not emitting light, to achieve a special light effect superimposed together with the light-transmitting pattern area 331 of the light-shielding layer 33.

[0085] like Figure 3As shown, the display module 3 is arranged adjacent to the operating element 2 for operating the home appliance 200 and configured such that the display mode of the display module 3 is associated with the operating state of the operating element 2, thus constituting the control module 1 for the home appliance 200 according to an embodiment of the present invention. Note that Figure 3 The accompanying drawings only schematically illustrate the operating element 2 and do not constitute any limitation on the operating element 2, particularly its form and location. The operating element 2 can be a physical button, knob, rotary knob, toggle / slide element, etc., or a touch-sensitive element on a touch film, or other suitable element for operating the household appliance 200.

[0086] In a preferred embodiment, the operating element 2 is a switch element of the household appliance 200, and when the household appliance 200 is in the on state corresponding to the switch element being on, the light-emitting element 31 emits light and the display area 301 displays a second display effect. Correspondingly, when the household appliance 200 is in the off state corresponding to the switch element being off, the light-emitting element 31 does not emit light and the display area 301 displays a first display effect.

[0087] In a preferred embodiment, the luminous efficacy of the predetermined light intensity variation of the second display effect is that the light intensity gradually weakens as it moves away from the operating element 2 along the light-emitting strip.

[0088] In a preferred embodiment, the display module 3 is further configured to produce a constant light intensity effect from the light emitted by the light-emitting element 31, such that in the portion of the display area 301 corresponding to the operating element 2, the second display effect includes a constant light intensity effect. In one example, the light-emitting element 31 may include a dedicated light-emitting element 31 corresponding to the operating element 2, and this dedicated light-emitting element 31 is used directly to display a constant light intensity effect in the portion of the display area 301 corresponding to the operating element 2. In an alternative example, the light guide 32 may be designed to include a light guide branch with constant transparency and configured to guide light from the light-emitting element 31 to the portion of the display area 301 corresponding to the operating element 2, thereby enabling that portion of the area to display a constant light intensity effect. Of course, the constant light intensity effect in this portion of the area can also be achieved by any other suitable means.

[0089] In a preferred embodiment, in the portion of the display area 301 corresponding to the operating element 2, the display area 301 has a predetermined pattern, and the first display effect includes a fourth preset color. That is, in the portion of the display area 301 corresponding to the operating element 2, the light-transmitting decorative ink of the light-transmitting display area 341 has the fourth preset color and forms a predetermined pattern. Furthermore, the second display effect with constant light intensity has a fifth preset color.

[0090] In a preferred embodiment, the fourth preset color is different from the fifth preset color.

[0091] In a preferred embodiment, the fifth preset color is the same as the third preset color of the light effect of the predetermined light intensity change of the second display effect.

[0092] For example, the fourth preset color can be silver or white, and the fifth preset color can be the same as the third preset color, which is blue-green.

[0093] like Figure 5 As shown, the display module 3 or operation module 1 can be integrated into the display panel 100 for the home appliance 200. In a preferred embodiment, the display area 301 of the display module 3 extends along the second direction on the front surface of the display panel 100.

[0094] In a preferred embodiment, the display panel 100 includes: a substrate 110 on which a light-emitting component and a light-emitting element 31 are integrated; a light guide plate 120 for guiding light from the light-emitting component, and the light guide element 32 of the display module 3 is integrally formed with the light guide plate 120; a color filter layer 130 on which a light-transmitting functional pattern is drawn and a light-shielding ink is coated in areas other than the functional pattern, and in the case that the display module 3 has a light-shielding layer 33, the light-shielding layer 33 is integrally formed with the color filter layer 130; and an outer decorative layer 140, the decorative layer 34 of the display module 3 is integrally formed with the outer decorative layer 140.

[0095] In a preferred embodiment, the display panel 100 is a touch display panel including a touch film 150. The touch film 150 is disposed between the color filter layer 130 and the outer decorative layer 140 and is light-transmitting. It also has functional touch buttons corresponding to the functional patterns on the color filter layer 130. Furthermore, the touch film 150 can be integrated with the color filter layer 130 by means of, for example, bonding, or it can be formed by directly printing touch circuitry onto the color filter layer 130.

[0096] Furthermore, when the operation module 1 is integrated into the display panel 100, if the operation element 2 is a physical element such as a button, it can be integrated on the substrate 110, and if the operation element 2 is a touch sensing element, it can be integrated on the touch film 150 of the display panel 100. Of course, other appropriate configurations are also feasible.

[0097] In a preferred embodiment, such as Figure 6 As shown, the outer decorative layer 140 includes a transparent material layer 141 located on the outer side facing the user and an ink layer attached to the inner side of the material layer 141 facing away from the user. The ink layer extends from the inside out (along...) Figure 6The hollow arrow (in the direction of the arrow) sequentially includes a light-diffusing ink layer 142 for uniformly distributing transmitted light, a colored light-transmitting ink layer 143, and a blocking ink layer 144 for blocking non-display areas. Both the opaque decorative ink and the light-transmitting decorative ink of the decorative layer 34 of the display module 3 are located in the blocking ink layer 144. The transparent material layer 141 can be made of acrylic, glass, etc. The ink layer can be attached to the material layer 141 through printing or in-film transfer processes. The touch film 150 can also be formed integrally with the ink layer by bonding or directly printing touch circuitry as described above, or the ink layer, touch film 150, and color filter layer 130 can be formed as a single unit.

[0098] Although specific embodiments have been described above, these embodiments are not intended to limit the scope of this utility model, even when only a single embodiment is described with respect to a particular feature. The feature examples provided in this utility model disclosure are intended to be illustrative and not limiting, unless otherwise stated. In specific implementations, multiple features may be combined with each other as needed and where technically feasible. Various substitutions, modifications, and alterations may also be conceived without departing from the spirit and scope of this utility model.
