Description

Technical Field

[0001] This invention belongs to the field of household appliance technology, specifically, it relates to a display component, display device, and display control method for a household appliance. Background Technology

[0002] Most existing home appliance products use digital and graphic descriptions to interact with users. However, these methods require a large display area, which fails to meet the minimalist display requirements of some users. Furthermore, existing display devices often have complex structures to display digital and graphic content, leading to higher overall costs and hindering cost control in the home appliance industry.

[0003] Chinese Patent Application No. 202021654369.1 discloses a washing machine control panel assembly, including a panel body installed on the washing machine casing. The panel body includes a light strip plate, a mounting base, and a light-transmitting plate. A light source is integrated on the light strip plate, and the light-transmitting plate is fixedly fitted onto the mounting base. The mounting base includes a hollow portion. After installation, the hollow portion is sandwiched between the light strip plate and the light-transmitting plate, forming a light propagation channel. The light source is located within the propagation channel, and the light emitted by the light source shines onto the light-transmitting plate through the propagation channel, so as to present the light emitted by the light source on the light-transmitting plate.

[0004] However, in the above scheme, the light emitted by the light source propagates through the air and shines on the light-transmitting plate. On the outside of the light-transmitting plate, what is actually observed is one or more light spots that are similar in shape to the light source, and the display effect is not aesthetically pleasing.

[0063] like Figures 1 to 10 As shown, embodiments of the present invention provide a display component 200 for a household appliance, a display device having the display component 200, and a display control method for a household appliance having the display device.

[0064] Specifically, the household appliances mentioned can be clothing processing equipment, such as washing machines, dryers, washer-dryer combos, and garment care machines, or dishwashers, refrigerators, etc.

[0065] In an embodiment of the present invention, the display device has a display panel bracket 100, which fixes the display device to a household appliance. The display component 200 is mounted on the display panel bracket 100 and can achieve corresponding display effects under the control of a controller, used to provide feedback to the user on the working status of the household appliance.

[0066] Specifically, the display assembly 200 provided in this embodiment includes a light source component 210, a light guide component 220, and a display component 230. The light source component 210 emits light, the light guide component 220 receives the light emitted by the light source component 210 and transmits it to the display component 230, and the display surface 231 of the display assembly 200 is disposed on the display component 230. The light is ultimately emitted from the display surface 231 to achieve the display effect.

[0067] In this embodiment, the display component 200 has a narrow strip structure, which can achieve a strip-like display effect and reduce the space occupied on the display panel bracket 100. Therefore, this embodiment adopts the following technical solution.

[0068] The light guide 220 of the display assembly 200 has a certain extension length, and the light source component 210 is disposed on the light guide 220. The display component 230 is disposed on one side of the light guide 220 and extends in the same direction as the light guide 220. The light emitted by the light source component 210 passes through the light guide 220, diffuses, and then passes through the display component 230 before being emitted.

[0069] More specifically, the side of the display element 230 facing away from the light guide 220 is the display surface 231 of the display assembly 200. This display surface 231 faces the user and is elongated. The light diffused by the light guide 220 passes through the display element 230 and is emitted from the display surface 231, thus presenting a certain display effect on the display surface 231.

[0070] In the above scheme, the display component 200 can uniformly illuminate the display surface 231 by setting a light guide 220 that can diffuse light, so that the overall brightness of the elongated display surface 231 is uniform and there is no obvious difference between light and dark, resulting in a more beautiful display effect.

[0071] In one specific implementation, the light source component 210 includes a plurality of light-emitting elements 211 distributed along the length of the light guide 220. When the plurality of light-emitting elements 211 distributed in succession are lit at the same time, the light guide 220 diffuses the light, so that the display surface 231 can be evenly lit within a certain length range without the appearance of alternating bright and dark light spots.

[0072] In one specific structure, the light-emitting element can be directly mounted on the light guide. In another specific structure, several light-emitting elements are connected into a whole by a support structure and then mounted on the light guide.

[0073] In one specific embodiment, the light source component 210 includes a strip-shaped circuit board on which multiple light-emitting elements 211 are distributed along the length direction. Using the circuit board as a support structure, the multiple light-emitting elements 211 can be integrally mounted onto the light guide component 220.

[0074] In one detailed embodiment, the light source component 210 is a PCB light strip, including a PCB board and several LED beads disposed on the PCB board as light-emitting elements 211. The PCB light strip preferably uses an RGB light source, which can achieve the display of multiple colors, such as a color gradient display along its length, thus achieving richer display effects.

[0075] In this embodiment, the display component 200 has the above-described structure, realizing an extremely narrow display structure using a strip light as the light source component 210, and the display surface 231 can be uniformly lit when the light source component 210 emits light, resulting in a more aesthetically pleasing display effect.

[0076] Furthermore, in this embodiment, the display element 230 and the light guide element 220 are separate structures, manufactured separately, and then the display element 230 is mounted on the light guide element 220. The light guide element 220 is used to diffuse light so that the light shines evenly onto the display element 230, and the display element 230 allows the light to pass through and exit. The separate structure makes it convenient to use different materials to manufacture the light guide element 220 and the display element 230.

[0077] As one specific implementation, the display component 230 can be mounted on the light guide component 220 via a plug-in structure, which is simple to assemble and easy to implement.

[0078] In a further embodiment, by setting a light-blocking structure, the light emitted by the light source component 210 is directed as much as possible to the light guide component 220, reducing the divergence of light in other directions, thereby allowing more light to be transmitted to the display component 230 and improving the display brightness.

[0079] In one specific embodiment, the display device has a mounting slot for mounting the display component, the display component being embedded in the mounting slot, and the inner wall of the mounting slot serving as the light-blocking structure.

[0080] More specifically, in the display assembly, the light source component, the light guide component, and the display component are arranged sequentially along the direction of light propagation, with the light-emitting element positioned in front of the light source component and emitting light towards the light guide component. The display component is mounted in front of the light guide component via a plug-in structure.

[0081] When the light-emitting element is lit, some of the light propagates directly forward, diffuses through the light guide, and then reaches the display. Although some light propagates upward and downward, this portion of light is blocked by the upper and lower side walls of the mounting slot, preventing light leakage and significant loss of brightness.

[0082] It should be noted that, in the embodiments of the present invention, the "front side" refers to the side facing the user when the display component 200 is mounted on the home appliance via the display panel bracket 100. Correspondingly, the "rear side" refers to the side facing away from the user.

[0083] In another specific implementation, the light guide 220 is at least partially disposed around the outer periphery of the light source component 210, so that the light emitted by the light source component 210 can basically enter the light guide 220, and then the light guide 220 refracts and / or scatters the light, thereby transmitting it to the display component 230.

[0084] In one specific structure, the light source component has a light-emitting element disposed on the front side, and the light guide is at least surrounding the upper and lower sides and the front side of the light source component, so that almost all the light enters the light guide.

[0085] By adopting the above solution, the light guide 220 itself forms the light-blocking structure, so that light emitted in different directions can enter the light guide 220 without leaking to areas outside the light guide 220, and more light can be transmitted to the display 230.

[0086] In one specific embodiment of this example, the light guide 220 is made of a light guide material or a light uniform material. When the light source component 210 emits light, the light guide 220 can emit light throughout, thereby illuminating the display surface 231 on the front side of the display component 230 evenly.

[0087] In one specific embodiment, the light guide 220 is made of a light guide material and has several light guide points on the incident surface of the light to refract the light at multiple angles. When the light enters the light guide 220, it is refracted in multiple directions, thereby achieving the effect of the light guide 220 emitting light throughout.

[0088] In another specific embodiment, the light guide 220 is made of a light-dispersing material, which refers to a material in which diffusing particles are uniformly dispersed in the matrix. When light enters the light guide 220, it is reflected multiple times by the dispersed diffusing particles as it propagates inside the light guide 220, causing the light to propagate at multiple angles. The light guide 220 achieves the effect of emitting light throughout by scattering the light through the light-dispersing material.

[0089] In one specific embodiment of this example, the light guide 220 is a hollow strip structure with an internal cavity 221 extending along its length, and the light source component 210 is disposed in the internal cavity 221.

[0090] Specifically, the two ends of the internal cavity 221 are open structures, through which the light source component 210 can be installed into the internal cavity 221.

[0091] In one specific structure, the circuit board of the light source component 210 is fitted to the lower sidewall of the internal cavity 221, and the light-emitting element 211 is disposed on the upper side of the circuit board. The display component 230 is disposed in front of the light guide component 220. When the light-emitting element 211 emits light, the light enters the light guide component 220 through the inner surface of the light guide component 220, illuminating the entire light guide component 220, and finally transmitting the light to the display surface 231 in front of the display component 230. Since the light source component 210 is completely surrounded by the light guide component 220, there is essentially no problem of light leakage.

[0092] In a preferred embodiment, the outer surface of the light guide 220, including its outer peripheral wall and two end walls, is covered with a light-shielding layer (not shown in the figure) in all areas except the front side facing the display 230. Thus, light rays emanating from the top, bottom, left, right, and rear of the light guide 220 are folded by the light-shielding layer and cannot escape, and may even be partially reflected, thereby concentrating the light rays emitted from the front side of the light guide 220 and improving the display brightness of the display surface 231.

[0093] In another preferred embodiment, light-shielding layers can be provided on the upper and lower sides and the rear side of the inner surface of the light guide 220, so that light can only enter the light guide 220 from the front side, and thus be transmitted to the display component 230 in a more concentrated manner. More preferably, the light-shielding layer has a reflective effect, and the light shining on the light-shielding layer can be reflected and then enter the light guide 220 from the front side, further reducing light loss.

[0094] In a further preferred configuration, the outer surface of the display component 200, except for the display surface 231, is covered with a light-shielding layer to prevent unnecessary light scattering. When the display component 200 is mounted on the display panel bracket 100, only the display surface 231 is located on the exterior of the display device. This structure prevents light from escaping from areas outside the display surface 231, ensuring the display effect at the display surface 231.

[0095] In one specific structure, the display panel bracket 100 is provided with a mounting groove 110 with a front opening, and the display assembly 200 is embedded in the mounting groove 110. The display element 230 is close to the front opening of the mounting groove 110, so that the display surface 231 is exposed to the outside through the front opening of the mounting groove 110.

[0096] In one specific embodiment, the light-shielding layer is a thin film made of an opaque material. The film is adhered to the surface of the light guide 220 and the display 230 to achieve a light-shielding effect.

[0097] As another specific implementation, the light-shielding layer is formed by coating the surfaces of the light guide 220 and the display 230 with an opaque coating, thereby achieving the effect of preventing light scattering.

[0098] In this embodiment, the light source component 210, the light guide component 220, and the display component 230 are all strip-shaped structures with a certain length. The display component 200 formed by the assembly of the three is generally a narrow strip shape, with a simple structure, which reduces the installation space occupied by the display component 200 on the display device.

[0099] Furthermore, after the display component 200 is embedded in the mounting slot 110, the display surface 231 is basically flush with the front surface of the display device, ensuring the aesthetics of the overall structure of the display device.

[0100] As one specific implementation, the light guide 220 has a uniform cross-sectional structure along its length direction, that is, the cross-sectional shape and size of the light guide 220 are consistent at any position along its length direction.

[0101] The light guide 220 has a uniform cross-section structure and can be manufactured by extrusion to form a structure with an internal cavity 221. The light guide 220 can be directly extruded without the need for post-processing to create the internal cavity 221, thus simplifying the manufacturing process.

[0102] Furthermore, in this embodiment, the display surface 231 of the display element 230 is adapted to the appearance of the display device, and can be either a plane or a curved surface. When the display surface 231 is curved, the display element 230 has a variable cross-section structure along its length direction, that is, the cross-sectional shape and size of the display element 230 vary.

[0103] In a specific structure, combined Figure 3 and Figure 7 As shown, the front of the display device has a structure in which the middle area protrudes forward relative to the two end areas, and correspondingly, the display surface 231 is a curved surface in which the middle area protrudes forward.

[0104] As one specific implementation, the display component 230 is an injection molded part made using plastic injection molding technology, which can easily form a variable cross-section structure without the need for complex processes.

[0105] In this specific embodiment, the light guide 220 and the display component 230 are separate components, which can be manufactured separately, and then the display component 230 is mounted on the light guide 220 to form an integral structure. The display component 230 is a solid structure and can be manufactured using injection molding to achieve various external shapes, thus flexibly adapting to the appearance of the display device. The light guide 220 is a hollow strip structure with an internal cavity 221. It is designed as a constant cross-section structure, and the internal cavity 221 can be formed using an extrusion process.

[0106] If the light guide and the display are integrated, they can only be manufactured by first injection molding the external shape and then machining the internal cavity, which is more complicated and also wastes raw materials.

[0107] In one specific embodiment of this invention, the display element 230 and the light guide element 220 are assembled by a plug-in connection. Specifically, the display element 230 is mounted on one side of the light guide element 220 via a plug-in structure.

[0108] In one specific structure, the insertion structure includes an insertion portion protruding from the front side of the light guide and an insertion slot correspondingly disposed on the display component. The insertion portion is inserted into the insertion slot, thereby fixing the display component and the light guide component relative to each other.

[0109] In another specific structure, the plug-in structure includes a plug-in groove 222 disposed on the front side of the light guide 220 and a plug-in portion 232 protruding on the surface of the display 230. The two are plugged in to assemble the display 230 and the light guide 220 into one unit.

[0110] In one specific embodiment, the front surface of the light guide 220 is recessed to form an insertion groove 222, which extends from the left end wall to the right end wall of the light guide 220. The rear surface of the display 230 has a protruding insertion portion 232, which can be inserted into the insertion groove 222 along its length from one end of the insertion groove 222.

[0111] Furthermore, the insertion portion 232 is provided at least at both ends of the display component 230 along its length. Since the light guide component 220 and the display component 230 are strip-shaped structures with a large length dimension, providing the insertion portion 232 at at least at both ends enables the assembly and fixation of the display component 230 and the light guide component 220, resulting in a more stable structure.

[0112] As a specific structure, the plug-in portion 232 can be distributed in multiple intervals along the length direction of the display component 230, thereby further enhancing the stability of the display component 230 and the light guide component 220 after assembly.

[0113] As another specific structure, the insertion portion 232 extends continuously along the length of the display component 230, with both ends flush with the end walls of the display component 230. In this way, the display component 230 achieves insertion and engagement with the light guide component 220 throughout its entire length, resulting in a more stable structure.

[0114] In a further embodiment, the sidewall of the insertion slot 222 has a protruding limiting portion 223 in the area away from the bottom of the slot, and the sidewall of the insertion portion 232 is provided with a mating recess 233 that engages with the limiting portion 223. The limiting portion 223 and the mating recess 233 restrict the movement of the display component 230 in the front-back direction, preventing the insertion portion 232 from dislodging from the insertion slot 222 and causing the display component 230 to separate from the light guide component 220.

[0115] The insertion slot 222 has a through-end structure, so the insertion part 232 can be inserted from the end of the insertion slot 222 during assembly. The display part 230 and the light guide 220 will not be unable to be assembled due to the setting of the limiting part 223 and the mating recess 233.

[0116] In one specific embodiment, the upper and lower side walls of the insertion groove 222 have relatively protruding limiting portions 223 at the front end, and the upper and lower side walls of the insertion portion 232 are recessed in the area near the display component 230 to form a mating recess 233. The limiting portions 223 and the mating recesses 233 are respectively provided to extend continuously along the length direction of the display component 200.

[0117] In a more specific structure, the rear side of the limiting part 223 has a rounded corner structure, which abuts against the arc-shaped surface of the rear side of the mating recess 233, and there is a gap between the protruding top of the limiting part 223 and the deepest part of the mating recess 233. After the display component 230 and the light guide component 220 are assembled, the front side of the light guide component 220 abuts against the rear side of the display component 230, and with the limiting effect of the limiting part 223 and the mating recess 233, the movement of the display component 230 in the front-back direction can be restricted.

[0118] Furthermore, there is a gap between the upper and lower sides of the plug-in portion 232 and the upper and lower sides of the plug-in groove 222. By the rounded corner structure of the two side limiting portions 223 and the arc-shaped surface of the mating recess 233, the up and down movement of the plug-in portion 232 relative to the plug-in groove 222 is restricted, thereby achieving the limitation of the display component 230 in the up and down direction.

[0119] In the above structure, there is a certain gap between the rear end of the insertion part 232 and the bottom surface of the insertion groove 222, and the protruding top of the limiting part 223 does not contact the deepest part of the mating recess 233. The insertion part 232 and the insertion groove 222 only form line contact between the rounded corner structure of the limiting part 223 and the arc-shaped surface on the rear side of the mating recess 233, and there is no large-area contact, which can reduce the friction when the insertion part 232 is inserted into the insertion groove 222.

[0120] Furthermore, the front side of the limiting part 223 is chamfered, which further reduces the contact area between the light guide 220 and the display part 230, thereby further reducing friction during assembly.

[0121] In a further embodiment, the mounting groove 110 on the display panel bracket 100 is a strip-shaped groove that extends from one end of the display panel bracket 100 to the other end.

[0122] As a specific structure, the mounting slot 110 is located near the top of the display panel bracket 100. The display assembly 200 is embedded in the mounting slot 110, which can present a strip-shaped display effect on the top front side of the display device.

[0123] Furthermore, the left and right ends of the mounting groove 110 are closed structures, and the length of the mounting groove 110 is basically the same as the length of the display component 200. Preferably, the mounting groove 110 and the display component 200 are interference-fitted in the length direction to facilitate assembly.

[0124] By designing the mounting slot 110 with closed ends, after the display component 200 is embedded in the mounting slot 110, the light source component 210, the light guide component 220, and the display component 230 are all limited in the left-right direction, thus preventing any relative movement between them. Therefore, after the light source component 210 is installed into the internal cavity 221 of the light guide component 220, no additional fixing is required. Similarly, after the display component 230 is plugged into the light guide component 220, no additional fixing is required.

[0125] In one specific embodiment, after the display component 230 and the light guide component 220 are connected and assembled, the upper side of the display component 230 is flush with the light guide component 220, and the lower front area has an extension portion 234 that extends downward and whose bottom end is lower than the lower side of the light guide component 220.

[0126] With the above structure, after the display component 200 is embedded in the mounting groove 110, the extension 234 at least partially covers the front opening of the mounting groove 110. On the one hand, this makes the display device more aesthetically pleasing overall; on the other hand, it also reduces the problem of dust accumulation in the assembly gap between the display component 200 and the mounting groove 110.

[0127] In a further embodiment, the light guide 220 is provided with a limiting structure, which cooperates with the display panel bracket 100 to fix the display component 200 in the mounting groove 110.

[0128] In one specific structure, the limiting structure includes a limiting groove 224 disposed on the surface of the light guide 220, and a locking protrusion 111 disposed on the inner wall of the mounting groove 110. When the display component 200 is embedded in the mounting groove 110, the locking protrusion 111 engages with the limiting groove 224, thereby limiting the display component 200.

[0129] In one specific implementation, after the display component 200 is embedded in the mounting groove 110, the display component 200 is fixed using an ultrasonic welding process.

[0130] It is understood that the method of fixing the display component 200 is not limited to ultrasonic welding. Other methods that can fix the display component 200, such as adhesive fixing, can also be applied in this embodiment.

[0131] The household appliance provided in this embodiment has the above-mentioned display device. When the household appliance is working, the display effect presented by the display component 200 can provide feedback to the user on the working status of the household appliance.

[0132] Specifically, the display control method for the household appliance includes: controlling the luminous color of the light source component 210 and / or the length of the luminous area of ​​the light source component 210 on the light guide 220 according to the working state of the household appliance.

[0133] The working status may include: the type of program currently running, the current stage of program execution, and one or more of the current program processes.

[0134] The following describes the display control method in detail, taking the household appliance as a clothing processing device as an example.

[0135] In one specific implementation, the garment processing device controls the light-emitting element 211 on the light source component 210 to emit different colors according to the currently running program type. Specifically, when the garment processing device runs different types of garment processing programs, it controls the light-emitting element 211 to emit different colors, thereby causing the display component 200 to display different colors, making it easier for the user to understand the currently running program type.

[0136] In another specific implementation, the garment processing device controls the light-emitting element 211 on the light source component 210 to emit different colors according to the current program's operating stage. For example, the garment processing program run by the garment processing device includes a washing stage, a drying stage, and a purification stage. When the garment processing program runs to different stages, the light-emitting element 211 is controlled to emit different colors, so that the display component 200 displays different colors, which can provide real-time feedback to the user on the current operating stage.

[0137] In another specific embodiment, the garment processing device controls the length of the light-emitting area of ​​the light source component 210 on the light guide 220 according to the current program progress. Specifically, the length of the light-emitting area can be controlled by controlling the number of light-emitting elements 211 that are lit simultaneously on the light source component 210.

[0138] In one specific embodiment, multiple light-emitting elements 211 on the light source component 210 are lit sequentially from one end as the clothing processing program runs, thus presenting a progress bar-like display effect, which can provide real-time feedback to the user on the current program progress.

[0139] In another specific scheme, when the program starts, multiple light-emitting elements 211 on the light source component 210 emit the same light color, and as the clothing processing program runs, starting from one of the light-emitting elements 211, they change to another light color in sequence, similar to a running horse effect, which can also achieve the purpose of real-time feedback on the program progress.

[0140] Furthermore, in this embodiment, the emission color of the light source component 210 can be controlled according to the program type or running stage, and the length of the emission area can be controlled according to the program progress. For example, different emission colors can be used for display in the washing, drying and purifying stages, and the length of the emission area can be adjusted according to the current progress in each stage. In this way, the user can intuitively understand the current running stage and program progress of the clothing processing program, resulting in a better user experience.

[0141] In one detailed embodiment, the display component 200 can also provide feedback on the complete progress of the garment processing procedure. Specifically, the garment processing procedure has multiple sequentially executed operating stages, each corresponding to a different light-emitting color. As the garment processing procedure runs, the light-emitting elements 211 at one end light up sequentially, with the light-emitting color corresponding to the first operating stage. When one operating stage is completed and the next operating stage begins, subsequent light-emitting elements 211 are lit up according to the light-emitting color corresponding to the next operating stage, and so on, until the garment processing procedure ends.

[0142] It is understandable that, in the above scheme, all light-emitting elements 211 can be controlled to light up simultaneously with the same light-emitting color when the program starts, and then change to the light-emitting color corresponding to the corresponding running stage as the clothing processing program runs.

[0143] In a further embodiment, the light source component 210 can be controlled to flash light to alert the user in special circumstances such as when the program finishes running or when a household appliance malfunctions. Specifically, when the program finishes running or when a household appliance malfunctions, the light source component 210 flashes light in different colors to help the user understand the working status of the household appliance in a timely manner.

[0144] The display component 200 provided in this embodiment has a narrow strip structure, which reduces the installation space occupied on the display device. The display component 200 has a simple structure and low manufacturing cost, and can achieve uniform light emission from the front display surface 231, resulting in better display effect. The light source component 210 can use a PCB light strip or a similar device, which has good display stability. The separate light guide component 220 and display component 230 simplify the manufacturing process and make it easier to flexibly adapt to the overall appearance of the display device.

[0145] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
