Description

Embodiments of the present invention relate to the field of household appliances, and in particular, to a panel, a panel component of a household appliance, and a household appliance.
With the intelligentization of household appliances, increasingly more household appliances are configured with panel components. The panel component may be configured to control the household appliance, and display related content such as use states and program options of the household appliance. The panel component mainly displays content through a panel. However, the existing panel has a poor display effect.
An object of the present invention is to provide a new panel with a desirable display effect, a panel component of a household appliance, and a household appliance.
To achieve the foregoing object, an embodiment of the present invention provides a panel, applied to a panel component of a household appliance. The panel component includes a main body and a display module. The display module includes one or more display objects configured to be illuminated or extinguished. The panel is connected to the main body and is configured to block the display module. The panel includes: an outer layer, including a display area and a non-display area, where light emitted when the display object is illuminated is allowed to be transmitted out of the display area; and an inner layer, located on a back side of the outer layer to block the light emitted when the display object is illuminated from being transmitted out of the non-display area.
Compared with the prior art, the technical solutions of the embodiments of the present invention have the following beneficial effects.
In the embodiments of the present invention, the outer layer is configured as the display area and the non-display area. The outer layer of the panel is light-transmissive, and when the display object is illuminated, the light emitted when the display object is illuminated passes through the outer layer. Therefore, a user can see the illuminate display object through the display area of the panel, so that the display area can display the display object. Since the inner layer can block the light emitted when the display object is illuminated from being transmitted out of the non-display area, the light emitted when the display object is illuminated can be gathered in the display area to avoid loss of the light. In this way, a display brightness of the display object is ensured, and the light emitted when the display object is illuminated is prevented from being transmitted out of only the display area, thereby improving a display effect of the panel.
Optionally, the display area of the inner layer close to the outer layer has a first transition section, and a thickness of the first transition section is less than a thickness of another area of the inner layer. The first transition section may enable the inner layer close to the display area to naturally and smoothly transition to avoid a sudden change in a wall thickness, so as to reduce or even hopefully eliminate a visual difference caused by the sudden change in the wall thickness, thereby improving the display effect. In addition, poor appearance caused by shrinkage as a result of the change in the wall thickness may also be avoided, to ensure the appearance effect of the panel.
Optionally, a ratio of a length of the first transition section to the thickness of the first transition section is greater than a preset ratio, and the length of the first transition section is a length in a length direction of the panel.
Optionally, the outer layer has a second transition section matching the first transition section, and a thickness of the second transition section gradually decreases in a direction from the display area to a point away from the display area. In this way, a total thickness of the panel may be ensured to satisfy a total thickness limit of a space of the panel component.
Optionally, an end of the second transition section away from the display area is provided with a first curved transition surface, and/or an end of the second transition section close to the display area is provided with a second curved transition surface, so that a transition between the two ends of the second transition section and a nearby area is relatively smooth, thereby further reducing a probability of a shrinkage phenomenon as a result of the change in the wall thickness.
Optionally, the first curved transition surface is an arc-shaped transition surface, and/or the second curved transition surface is an arc-shaped transition surface.
Optionally, the inner layer is arranged at least on a periphery of the display area. In this way, an arrangement area of the inner layer may be reduced while the inner layer blocks the light emitted when the display object is illuminated from being transmitted out of the non-display area, which facilitates a reduction in costs.
Optionally, the inner layer covers the non-display area of the outer layer, which helps ensure consistency of a uniform color of the non-display area of the panel and improve an overall appearance effect of the non-display area of the panel.
Optionally, the inner layer protrudes from the back side of the outer layer or is flush with the back side of the outer layer.
Optionally, in a thickness direction of the outer layer, at least part of an edge of the outer layer has a protrusion, and the protrusion protrudes from the back side of the outer layer to block the inner layer. In this way, integrity of the panel may be better, and the appearance effect of the panel may also be improved.
Optionally, the inner layer is opaque or has a transparency less than a set light transmission threshold.
Optionally, the outer layer is obtained by injection molding on the inner layer, or the inner layer is obtained by injection molding on the outer layer.
Optionally, the display area and the non-display area are made of a same material and are translucent, and the outer layer is further configured to shield the display module when the display object is extinguished. When the display object is extinguished, the display module is shielded through the display area, so that the display module behind the display area is not easily perceived by the user or is not displayed. Moreover, the non-display area and the display area are made of a same material and are translucent, so that the inner layer behind the non-display area is not easily perceived by the user or is not displayed, and the display area and the non-display area of the panel can present a uniform display effect as a whole, thereby improving the uniform display effect of the panel.
An embodiment of the present invention further provides a panel component of a household appliance, including: a main body; and a display module, connected to the main body and including one or more display objects configured to be illuminated or extinguished, and further including any panel described above, where the panel is connected to the main body.
Optionally, a back side of the inner layer is provided with a mounting structure, and the mounting structure is configured to connect the panel to the main body. The inner layer may block some structures located below the inner layer from being displayed or perceived, and has a better visual effect. In addition, the mounting structure is located on a back side of the inner layer, which helps implement assembly of a front side of the panel, satisfy assembly requirements of the front side, and improve convenience of the mounting. Moreover, it is helpful to enable a boundary of the outer layer to extend to an outermost side of the panel, to achieve a window display effect with a maximum boundary, and realize better aesthetics.
The present invention further provides a household appliance, including any panel component described above.

A specific structure of a panel 1 is described below with reference to FIG. 1 to FIG. 9. In the figures, X represents a thickness direction of the panel 1, Y represents a length direction of the panel 1, and Z represents a width direction of the panel 1.
The panel 1 provided in an embodiment of the present invention may be applied to a panel component 100 of a household appliance. Refer to the following figures. FIG. 11 is a schematic structural diagram of a panel component according to an embodiment of the present invention from a perspective. FIG. 12 is a left view of FIG. 11. FIG. 13 is a schematic structural diagram of FIG. 11 from another perspective. FIG. 13 is illustrated from a viewpoint of a user facing the panel component 100 with a line of sight perpendicular to the panel 1.
The panel component 100 includes a main body 3 and a display module (not shown in the figure). The display module includes one or more display objects configured to be illuminated or extinguished. The panel 1 is connected to the main body 3 and configured to block the display module.
In a specific implementation, the panel 1 includes an outer layer 11 and an inner layer 12. The outer layer 11 may include a display area 111 and a non-display area 112. Light emitted when the display object is illuminated is allowed to be transmitted out of the display area 111. The inner layer 12 is located on a back side 11b of the outer layer 11 to block the light emitted when the display object is illuminated from being transmitted out of the non-display area 112.
The display object may be a character, a pattern, or a light-emitting component. When the display object is the character or the pattern, the display object such as the character or the pattern may be illuminated by turning on the light-emitting component (such as a light-emitting diode) corresponding to the character or the pattern, so that the panel component 100 can display the character or the pattern. When the display object is a light-emitting component, requirements of some scenes for ambient lighting may be satisfied, for example, a requirement that a light ring should be emitted around a knob. As an example, a ring light is arranged around a knob 4.
As shown in FIG. 1, a shape of the display area 11 may be a rectangle, a circle, or a ring. It may be understood that the shape of the display area 11 may also be various other suitable shapes, which is not limited herein.
In the embodiment of the present invention, a side of the outer layer 11 facing the user is denoted as a front side 11a, and the front side 11a is away from the inner layer 12. A side of the outer layer 11 facing away from the user is denoted as the back side 11b, and the back side 11b faces the inner layer 12.
Through the foregoing solution, the outer layer 11 is configured as the display area 111 and the non-display area 112. The outer layer 11 of the panel 1 is light-transmissive, and when the display object is illuminated, the light emitted when the display object is illuminated passes through the outer layer 11. Therefore, a user can see the illuminated display object through the display area 111 of the panel 1, so that the display area 111 can display the display object. The inner layer 12 can block the light emitted when the display object is illuminated from being transmitted out of the non-display area 112, and the light emitted when the display object is illuminated is gathered in the display area 111, so as to effectively avoid loss of the light. In this way, a display brightness of the display object is ensured, and the light emitted when the display object is illuminated is prevented from being transmitted out of only the display area 111, thereby improving a display effect of the panel 1.
In some non-limiting embodiments, the display area 111 and the non-display area 112 of the outer layer 11 are made of the same material and are translucent. The outer layer 11 is further configured to shield the display module when the display object is extinguished. In this way, when the display object is illuminated, the display area 111 can display the display object. When the display object is turned off, the display module is shielded through the display area 111, so that the display module behind the display area 111 is not easily perceived by the user or is not displayed. Moreover, the non-display area 112 and the display area 111 are made of the same material and are translucent, so that the inner layer 12 behind the non-display area 112 is not easily perceived by the user or is not displayed. Further, the display area 111 and the non-display area 112 of the panel 1 can present a uniform display effect as a whole, and the panel 1 may present a better overall appearance.
In some embodiments, the inner layer 12 is arranged at least on a periphery of the display area 111. In other words, on the back side 11b of the outer layer 11, an area of the non-display area 112 surrounding the display area 111 is provided with the inner layer 12. In this way, an arrangement area of the inner layer 12 may be reduced while the inner layer 12 blocks the light emitted when the display object is illuminated from being transmitted out of the non-display area 112, which facilitates a reduction in costs.
In some other embodiments, the inner layer 12 covers the non-display area 112 of the outer layer 11. In other words, the inner layer 12 is arranged in areas corresponding to the non-display area 112 on the back side 11b of the outer layer 11.
In a specific implementation, with reference to FIG. 5 and FIG. 6, the display area 111 of the inner layer 12 close to the outer layer 11 has a first transition section 121, and a thickness of the first transition section 121 is less than a thickness of another area of the inner layer 12. The arranged first transition section 121 may enable the inner layer 12 close to the display area 111 to naturally and smoothly transition to avoid a sudden change in a wall thickness, so as to reduce or even hopefully eliminate a visual difference caused by the sudden change in the wall thickness, thereby improving the display effect. In addition, poor appearance caused by shrinkage as a result of the change in the wall thickness may also be avoided, to ensure the appearance effect of the panel 1.
In some non-limiting embodiments, the thickness of the first transition section 121 of the inner layer 12 gradually increases in a direction away from the display area 111.
Further, a ratio of a length L of the first transition section 121 to a thickness Δt of the first transition section 121 is greater than a preset ratio, and the length L of the first transition section 121 is a length in a length direction Y of the panel 1. The thickness Δt of the first transition section 121 is a thickness in the thickness direction X of the panel 1.
The preset value is obtained based on factors such as a size of the panel 1, a size of the display area 11, and a size of the inner layer 12. When the panel 1 is obtained by injection molding, the preset value is also related to a mutual pulling force generated between the outer layer 11 and the inner layer 12 due to an injection molding surface during injection molding.
In some non-limiting embodiments, a value range of the preset ratio is greater than or equal to 5.
In some embodiments, the display area 111 and the non-display area 112 of the outer layer 11 may have the same thickness. In this case, a thickness of the panel 1 at the area provided with the inner layer 12 may be greater than the thickness at the display area 111.
In some other embodiments, the display area 111 and the non-display area 112 of the outer layer 11 may have different thicknesses. For example, the thickness of the non-display area 112 is less than the thickness of the display area 111. The outer layer 11 has a recessed portion on the back side of the non-display area 112, and the inner layer 12 may be located in the recessed portion. A sum of the thicknesses of the inner layer 12 and the non-display area 112 may be less than the thickness of the display area 111, or may be greater than the thickness of the display area 111, and may also be equal to the thickness of the display area 111. In this way, it is helpful to flexibly configure a total thickness of the panel 1, to accommodate total thickness limitations for the panel component 100 in different spaces and improve universality of the panel 1.
It may be understood that the thickness of the non-display area 112 may alternatively be greater than the thickness of the display area 111 based on requirements of an actual application scenario.
In a specific implementation, based on the structural diagram of an outer layer in the embodiment of the present invention provided in FIG. 10, the outer layer 11 has a second transition section 113 matching the first transition section 121, and a thickness of the second transition section 113 gradually decreases in a direction from the display area 111 to a point away from the display area 111. In this way, through complementarity of the first transition section 121 and the second transition section 113, the total thickness of the panel 1 may be ensured to satisfy a total thickness restriction of a space of the panel component 100.
Further, the second transition section 113 is located at a position of the non-display area 112 close to the display area 111.
In some embodiments, contact surfaces of the first transition section 121 and the second transition section 113 match each other to improve a degree of fitting between the first transition section 121 and the second transition section 113.
Further, an end of the second transition section 113 away from the display area 111 is provided with a first curved transition surface 1131. Alternatively, an end of the second transition section 113 close to the display area 111 is provided with a second curved transition surface 1132. Alternatively, an end of the second transition section 113 away from the display area 111 is provided with a first curved transition surface 1131, and an end of the second transition section 113 close to the display area 111 is provided with a second curved transition surface 1132.
One of the first curved transition surface 1131 and the second curved transition surface 1132 is an arc-shaped transition surface, or the first curved transition surface 1131 and the second curved transition surface 1132 are both arc-shaped transition surfaces, which further reduces a probability of a shrinkage phenomenon as a result of the change in the wall thickness.
It should be noted that, for some scenarios that are not limited by the total thickness of the space of the panel component 100, the thicknesses of the outer layer 11 and the inner layer 12 may be configured based on thickness requirements of the outer layer 11 and the inner layer 12. The first transition section 121 may be configured on the inner layer 12, or the first transition section 121 may not be configured. The second transition section 113 may be configured on the outer layer 11, or the second transition section 113 may not be configured.
In a specific implementation, the inner layer 12 protrudes from a back side 11b of the outer layer 11 or is flush with the back side 11b of the outer layer 11.
In a specific implementation, in a thickness direction X of the outer layer 11, at least part of an edge of the outer layer 11 has a protrusion 114, and the protrusion 114 protrudes from the back side 11b of the outer layer 11 to block the inner layer 12. Specifically, the protrusion 114 shields a side wall 122 of the inner layer 12 in the thickness direction X. In this way, integrity of the panel 1 may be better, and the appearance effect of the panel 1 may also be improved.
In some non-limiting embodiments, the protrusion 114 covers the corresponding side wall 122.
The inner layer 12 is opaque or has a transparency less than a set light transmission threshold, to improve an effect of blocking the light emitted when the display object is illuminated from being transmitted out of the non-display area 112.
The inner layer 12 may be made of black or other colored plastic. For example, the inner layer 12 is made of an acrylonitrile-butadiene-styrene copolymer (ABS), an ABS engineering plastic (also referred to as an engineering plastic alloy, a copolymer of polycarbonate (PC) and ABS PC+ABS), polystyrene (PS), or the like.
The outer layer 11 is transparent or translucent. In other words, the outer layer 11 may be made of a transparent material or a translucent material. The outer layer 11 may be made of acrylic (also referred to as PMMA or organic glass), PC, and other types of light-transmissive window plastics.
Colors of the outer layer 11 and the inner layer 12 may be the same or different. Hardness of the outer layer 11 and the inner layer 12 may be the same or different, which may be configured based on overall appearance requirements and assembly requirements of the panel 1.
For example, in a typical application scenario, the inner layer 12 is made of a black opaque material, and the outer layer 11 is made of a black translucent material. In this way, during display of the illuminated display object in the display area 111, when the display object is extinguished, the panel 11 may present a uniform black display effect.
To improve the display effect of the panel component 100, panel windows in panel components of some household appliances in the prior art are manufactured through inmode decoration (IMD). The IMD usually mainly includes in molding label (IML), in-mold film (IMF), in-mold roller (IMR), and the like. During IMD, a printed film is fed into a mold in various forms, and transfer of a multi-layer ink print or film attachment is performed on a part surface to realize a window decoration or window display effect. However, the panel manufactured by using the IMD process may realize an appearance effect of different colors, but it results in a surplus display effect for a window display part or a surplus overall opaque display effect that can be realized by using black or plastic particles. In addition, complexity and costs of the panel are both relatively high, and therefore the display effect and the costs of the panel cannot be desirably taken into account.
In the embodiment of the present invention, the panel 1 may be obtained by injection molding. For example, the panel may be obtained by injection molding by using the same set of molds. The panel 1 is obtained by injection molding, and the process is simple, which helps reduce costs. In particular, compared with the panel manufactured by using the IMD process, the panel obtained by injection molding can reduce costs while realizing the same function and helping ensure the display effect.
In some embodiments, the inner layer 12 is obtained by injection molding on the outer layer 11. In other words, the outer layer 11 may be obtained by injection molding, and then the inner layer 12 is injection molded on the outer layer 11, so as to obtain the panel 1.
In some other embodiments, the outer layer 11 is obtained by injection molding on the inner layer 12. In other words, the inner layer 12 may be obtained by injection molding, and then the outer layer 11 is obtained by injection molding on the inner layer 12, so as to obtain the panel 1.
A sequence of injection molding for the outer layer 11 and the inner layer 12 may be selected based on characteristics such as a melting temperature of the material and design of a mold.
The panel 1 provided in the embodiment of the present invention may be applied to the panel component 100 of the household appliance such as a control panel of a washing machine, a control panel of a clothes dryer, and a control panel of a washing and drying machine, to satisfy a window display function of the panel component 100.
An embodiment of the present invention further provides a panel component 100 of a household appliance. With reference to FIG. 1 to FIG. 13, the panel component 100 may include a main body 3, a display module (not shown in the figure), and a panel 1. The display module is connected to the main body 3. The display module includes one or more display objects configured to be illuminated or extinguished. The panel 1 is connected to the main body 3. The panel 1 may be the panel 1 provided in any of the foregoing embodiments. For a specific structure of the panel 1, reference may be made to the description in any of the foregoing embodiments. Details are not described herein again.
The back side of the inner layer 12 is provided with a positioning portion 2, and correspondingly, a positioning and mating portion is arranged on the main body 3. When the panel 1 is connected to the main body 3, the positioning portion 2 mates with the positioning and mating portion to implement mounting and positioning, so as to improve mounting convenience and mounting accuracy of the panel 1. Specific structures of the positioning portion 2 and the positioning and mating portion are not limited herein, as long as the positioning portion and the positioning and mating portion may match each other to implement mounting and positioning. For example, one of the positioning portion 2 and the positioning and mating portion is a positioning protrusion, and the other is a positioning groove.
For another example, one of the positioning portion 2 and the positioning and mating portion is a positioning post, the other is a protrusion having an accommodating cavity, and the positioning post is inserted into the accommodating cavity of the protrusion.
Further, the back side of the inner layer 12 may also be provided with a connection structure such as a hook, a glue tank, or an ultrasonic welding rib. The ultrasonic welding rib is configured to ultrasonically weld the panel 1 to the main body 3. The connection structure is arranged on the back side of the inner layer 12, which can help reduce costs of the panel 1, realize assembly of a front side of the panel 1 to the main body 3, satisfy the assembly requirements of the front side, and improve the mounting convenience of the panel 1. Moreover, since the connection structure does not need to be arranged on the outer layer 11, it is helpful to enable a boundary of the outer layer 11 to extend to an outermost side of the panel 1, to achieve a window display effect with a maximum boundary, and realize better aesthetics.
Since the positioning portion 2 is arranged on the back side of the inner layer 12, the positioning portion 2, another structure such as the hook, the glue tank, or the ultrasonic welding rib arranged on the back side of the inner layer 12, and some structures of the household appliance located below the inner layer 12 may be shielded and hidden through the inner layer 12, so that it is not easy for users to perceive from the front side of the panel 1, and the overall appearance effect of the panel 1 is improved.
An embodiment of the present invention further provides a household appliance, including the panel component provided in any of the foregoing embodiments. For a specific structure of the panel component, reference may be made to the description in the foregoing embodiments, and details are not described herein again.
