TECHNICAL FIELD

The present invention relates to a household appliance, and in particular, to a lighting assembly for a household appliance and a household appliance having the same.

BACKGROUND

Some current household appliances include a lighting assembly and a lighting effect of the lighting assembly is usually related to its size. As a result, it is harder to achieve a better lighting effect in a relatively limited space.

SUMMARY

An objective of the present invention is to provide an improved lighting assembly for a household appliance and a household appliance having the same.

For the above objective, one aspect of the embodiment of the present invention relates to a lighting assembly for a household appliance, including: a bracket including a through hole; a lampshade, where the lampshade and the bracket define a space and the lampshade includes a plate-shaped light outgoing portion; a circuit board mounted on the bracket and located outside the space; a light emitting device mounted on the circuit board; and a lens covering the light emitting device to refract light from the light emitting device, where the lens is located within the space through the through hole.

In a possible embodiment, the thickness of the circuit board is absorbed by the thickness of the bracket. In this way, the thickness of the lighting assembly may be reduced. The circuit board may be located within the range of the thickness of the bracket, so that the thickness of the circuit board is absorbed by the thickness of the bracket. In a possible embodiment, the bracket includes a mounting wall and a mounting groove recessed from the mounting wall to the light outgoing portion, at least a part of the circuit board is located within the mounting groove, and the light emitting device faces the light outgoing portion. When the circuit board is partially located within the mounting groove, the thickness of the circuit board may be partially absorbed by the thickness of the bracket. When the circuit board is completely located within the mounting groove, the thickness of the circuit board may be completely absorbed by the thickness of the bracket.

In a possible embodiment, a lampshade side wall of the lampshade is located on an outer side of a bracket side wall of the bracket, and an interval is provided between an end of the bracket side wall and the light outgoing portion. In this way, the light refracted by the lens may be transmitted out from the light outgoing portion after being reflected and scattered by the bracket side wall and the lampshade side wall. Light paths are complete, light emitting is uniform, and there is no shadow related to the bracket side wall.

In a possible embodiment, the bracket includes a protruding portion located on an inner side, and a distance is provided between the protruding portion and the end of the bracket side wall. In this way, mold forming may be facilitated and the shape of the protruding portion may be prevented from affecting an optical uniformity of the light outgoing portion 20 and causing an undesired shadow. The protruding portion may protrude inwardly from the bracket side wall. The bracket may be in the shape of a long box with one side open. There may be a plurality of protruding portions, which are distributed at intervals on two opposite bracket side walls in the length direction. There may be a plurality of lenses, which protrude at intervals on the mounting wall between the bracket side walls. There may be a plurality of light emitting devices, which may correspond to the lenses one to one.

In a possible embodiment, a minimum distance between the protruding portion and the light outgoing portion is not less than 6 millimeters. In this way, the shape of the protruding portion may be prevented from affecting the optical uniformity of the light outgoing portion and causing the undesired shadow. Numerical values herein may include values within an error range in measurement, calculation, or the like. The error range may be plus or minus five percent. For example, 6 millimeters may include 5.7 millimeters, 5.9 millimeters, 6 millimeters, 6.2 millimeters, 6.3 millimeters, or the like. The protruding portion may extend diagonally between the mounting wall and the bracket side wall. The minimum distance between the protruding portion and the light outgoing portion may be a straight line distance between a position on the protruding portion closest to the light outgoing portion and the light outgoing portion. There may be a smooth transition at a connection part between the protruding portion and the bracket side wall.

In a possible embodiment, the lampshade includes a lampshade side wall configured to be connected to the bracket, the bracket includes a bracket side wall connected to the lampshade side wall, and the lampshade side wall includes a locking hole snap-connected to the bracket side wall. In this way, a locking structure may be arranged on the bracket, but there is no locking structure on the lampshade, which avoids an optical defect of the locking structure formed at the light outgoing portion. In addition, from the light outgoing portion, the light emitting device or another optical abnormal point is invisible, and a molded surface is uniform and smooth, which is convenient for emitting light uniformly. The lampshade may be in the shape of a long box cover with one side open corresponding to the bracket. There may be a plurality of locking holes which may be separately arranged in rows at intervals on two opposite lampshade side walls in the length direction, to match a plurality of locking snaps on outer surfaces of the corresponding bracket side walls, so that the lampshade may be snap-connected to the bracket at a plurality of positions, which is steady and reliable.

In a possible embodiment, the bracket includes a mounting wall and a mounting groove recessed from the mounting wall to accommodate the circuit board. In this way, the thickness of the bracket may absorb the thickness of the circuit board. The circuit board may be approximately in a long strip shape, and its transverse size may be slightly smaller than that of a lens thereon. The length and width of the circuit board may be less than those of the bracket. The length and width of the mounting groove may be greater than or equal to those of the circuit board. Correspondingly, the length and width of the mounting groove may be less than those of the bracket. The depth of the mounting groove may be greater than or equal to the thickness of the circuit board. The circuit board may be embedded in the mounting groove. A plurality of through holes may be distributed at intervals on the mounting groove for the corresponding lenses to pass through respectively.

In a possible embodiment, one of the circuit board and the bracket includes a hot melt pole and the other includes a hole matching the hot melt pole. In this way, the circuit board and the bracket may be fixed to each other. The hot melt pole located on the bracket or the hole may be arranged inside the mounting groove.

In a possible embodiment, the circuit board is mounted on the bracket against an outer surface of the bracket. In this way, the size of the lighting assembly may be reduced.

In a possible embodiment, the lighting assembly includes a connector, and the circuit board includes an end portion connected to the connector. In this way, power may be provided for the lighting assembly. For example, the connector may be connected to a power supply of a household appliance, so as to provide power for the lighting assembly through a connection with the circuit board .

In a possible embodiment, the circuit board includes a main body portion having a larger transverse size than that of the end portion, the bracket includes gripping arms opposite to the main body portion and a connection groove between the gripping arms, the end portion is suitable to be connected to the connector in the connection groove, and the gripping arms include elastic hooks arranged face to face and extending toward the connection groove. In this way, the gripping arms may limit a longitudinal movement of the main body portion, the end portion and the connector are accommodated in the connection groove, and the gripping arms and the elastic hooks restrict transverse movement and longitudinal movement of the connector. The gripping arms may be arranged at the end portion of the bracket, and the connection groove may have an outward opening, making it convenient for the connector to enter from the opening and be connected to the end portion. When the connector enters or exits, the elastic hooks may move apart toward two sides and rebound after the entry or exit is completed.

In a possible embodiment, the bracket includes a mounting wall for mounting the light emitting device, a slanted wall extending from the mounting wall to the lampshade, and a bracket side wall extending from the slanted wall and received in the lampshade. In this way, the light emitted by the light emitting device may be reflected and scattered by the slanted wall and the bracket side wall after being refracted by a lens, so as to increase the light mixing distance, reduce the thickness, and improve the light emitting uniformity to uniformly emit light with a small thickness. The matching between the slanted wall and the bracket side wall or the like may control a light angle.

In a possible embodiment, the lampshade includes a lampshade side wall combined with the bracket side wall and the light outgoing portion connected to the lampshade side wall, to define the space together with the bracket. In this way, the lampshade side wall may scatter light, the light outgoing portion may transmit the light, and the light may be circulated and mixed in the space. Light paths are complete and light emitting is uniform.

In a possible embodiment, an inner surface of the bracket is made of a non-mirror material. In this way, the light emitted by the light emitting device may be scattered on the inner surface of the bracket after being refracted by the lens, and may be repeatedly circulated in the space formed by the lampshade and the bracket, so that the light incident on the light outgoing portion is more uniform and the lighting effect of the lighting assembly is better.

In a possible embodiment, the bracket is made of a reflective scattering material, and the lampshade is made of a transmissive scattering material. In this way, the light emitted by the light emitting device may be reflected and scattered by the bracket after being refracted by the lens, may be repeatedly circulated in the space formed by the lampshade and the bracket, and may be scattered on the lampshade, so that the light transmitted from the light outgoing portion is more uniform and the lighting effect of the lighting assembly is better.

In a possible embodiment, the bracket is made of a white plastic material, and the lampshade is made of a translucent haze material. In this way, the light emitted by the light emitting device may be reflected and scattered by the bracket after being refracted by the lens, may be scattered on the lampshade, and may be repeatedly circulated in the space formed by the lampshade and the bracket, so that the light transmitted from the light outgoing portion is more uniform and the lighting effect of the lighting assembly is better. The costs of the lighting assembly may also be controlled.

In a possible embodiment, the light emitted by the light emitting device may be refracted twice by the lens to obtain refracted light. The refracted light is scattered and reflected by the slanted wall and the bracket side wall, and is repeatedly circulated in the space to obtain scattered light. The scattered light may be transmitted by the light outgoing portion to obtain transmitted light. Before becoming the transmitted light, the light may be refracted, reflected, and scattered a plurality of times by the lens, the slanted wall, the bracket side wall, and the like inside the lighting assembly. The lighting assembly may achieve a lighting effect only in a longer light mixing distance with a smaller thickness, and the transmitted light may be distributed uniformly on the light outgoing portion, to lower a space requirement and ensure a lighting effect.

Another aspect of the embodiments of the present invention relates to a household appliance including the lighting assembly described above.

In a possible embodiment, the household appliance includes a storage compartment and an inner wall facing the storage compartment, and the lighting assembly is mounted on the inner wall. In this way, the lighting assembly may provide a better lighting effect for the storage compartment without a high space requirement. The household appliance may be a refrigeration appliance such as a refrigerator. The storage compartment may be located in a box body and be opened or closed by a door body. The storage compartment may include a refrigeration compartment, and may also include a freezing compartment. The inner wall may include a liner of the refrigerator, and may include one or more of a top wall, a side wall, a back wall, a bottom wall, and the like of the storage compartment.

In a possible embodiment, the inner wall includes an accommodating groove and the lighting assembly is accommodated in the accommodating groove. In this way, the storage space utilization of the storage compartment may be improved. In addition, the safety of the lighting assembly may be improved, and the possibility that the lighting assembly is hit unintentionally and damaged may be decreased. The accommodating groove may be a groove recessed from the inner wall away from the storage compartment. The shape, structure, and size of the accommodating groove may correspond to those of the lighting assembly. The depth, width, and length of the accommodating groove may be greater than or equal to the thickness, width, and length of the lighting assembly respectively.

In a possible embodiment, one of the accommodating groove and the lighting assembly includes recess portions, and the other includes locking portions combined with the recess portions. In this way, the combination of the accommodating groove 86 and the lighting assembly 10 may be convenient and reliable.

In a possible embodiment, the bracket includes the locking portions, protruding portions corresponding to the locking portions, and avoidance grooves between the locking portions and the protruding portions. In this way, mold forming may be facilitated and it may be ensured that the locking portions have enough height and elasticity.

In a possible embodiment, the locking portions are arranged in rows along a longitudinal direction, and the locking portions in the rows are staggered along a transverse direction. In this way, the lighting assembly may be snap-connected to the accommodating groove at a plurality of positions and the combination is firm. The locking portions may extend along the length of the bracket and the longitudinal direction from both sides of the bracket away from the lampshade, and are arranged in two rows. The number of locking portions arranged on one side of the bracket and the number of locking portions arranged on the other side of the bracket may be different, for example, 3 and 4 respectively. Each of the locking portions on one side of the bracket may correspond to an interval between two adjacent locking portions on the other side of the bracket. The locking portions are staggered along the width of the bracket and the transverse direction.

In a possible embodiment, the circuit board faces a bottom wall of the accommodating groove. In this way, the thickness of the lighting assembly may be smaller and the space requirement on the household appliance may be lower. There are no other structures between the circuit board and the accommodating groove, to reduce the thickness of the lighting assembly and lower a depth requirement on the accommodating groove.

DETAILED DESCRIPTION

FIG. 1 is a schematic structural diagram of a lighting assembly according to one aspect of embodiments of the present invention. Referring to FIG. 1, in some embodiments, a lighting assembly 10 for a household appliance includes a bracket 12 including a through hole 14. The through hole 14 may pass through the bracket 12.

The lighting assembly 10 includes a lampshade 16. The lampshade 16 and the bracket 12 define a space 18. The lampshade 16 includes a plate-shaped light outgoing portion 20. The space 18 may be located between the lampshade 16 and the bracket 12.

The lighting assembly 10 includes a circuit board 22 mounted on the bracket 12 and located outside the space 18. The circuit board 22 may be opposite to the light outgoing portion 20.

The lighting assembly 10 includes a light emitting device 24 mounted on the circuit board 22. The light emitting device 24 may include a light emitting diode. The light emitting device 24 may face the light outgoing portion 20.

The lighting assembly 10 includes a lens 26 covering the light emitting device 24 to refract light from the light emitting device 24. The lens 26 is located within the space 18 through the through hole 14. The lens 26 may be located between the light emitting device 24 and the light outgoing portion 20.

The embodiments of the present invention may lower a space requirement, ensure a lighting effect, and so on. For example, the lens 26 is located within the space 18 through the through hole 14, which may avoid a superposition of the thickness of the lens 26 and the thickness of the bracket 12 outside the space 18, so as to reduce the thickness of the lighting assembly 10. The plate-shaped light outgoing portion 20 may reduce the thickness of the lighting assembly 10 because the height of the light outgoing portion 20 is relatively small. The circuit board 22 is located outside the space 18, which may ensure a light mixing distance M and a light emitting uniformity of the lighting assembly 10, and the like. That is to say, the lighting assembly 10 may achieve a better lighting effect with a smaller thickness, lower a space requirement, ensure a lighting effect, and provide a plane light source that emits uniform light. The light mixing distance M may be a distance between the light emitting device 24 and the light outgoing portion 20.

In some embodiments, the thickness of the circuit board 22 is absorbed by the thickness of the bracket 12.

In this way, the thickness of the lighting assembly 10 may be reduced. The circuit board 22 may be located within the range of the thickness of the bracket 12, so that the thickness of the circuit board 22 is absorbed by the thickness of the bracket 12.

In some embodiments, the bracket 12 includes a mounting wall 28 and a mounting groove 30 recessed from the mounting wall 28 to the light outgoing portion 20, at least a part of the circuit board 22 is located within the mounting groove 30, and the light emitting device 24 faces the light outgoing portion 20.

In this way, the thickness of the circuit board 22 may be partially or completely absorbed by the thickness of the bracket 12, and the light emitted by the light emitting device 24 may be propagated outward through the light outgoing portion 20.

When the circuit board 22 is partially located within the mounting groove 30, the thickness of the circuit board 22 may be partially absorbed by the thickness of the bracket 12. When the circuit board 22 is completely located within the mounting groove 30, the thickness of the circuit board 22 may be completely absorbed by the thickness of the bracket 12.

In some embodiments, a lampshade side wall 32 of the lampshade 16 is located on an outer side of a bracket side wall 34 of the bracket 12, and an interval is provided between an end 36 of the bracket side wall 34 and the light outgoing portion 20. In this way, the light refracted by the lens 26 may be transmitted out from the light outgoing portion 20 after being reflected and scattered by the bracket side wall 34 and the lampshade side wall 32. Light paths are complete, light emitting is uniform, and there is no shadow related to the bracket side wall 34.

The height of the bracket side wall 34 may be smaller than that of the lampshade side wall 32, so that the interval is provided between the end 36 and the light outgoing portion 20 when the bracket 12 is combined with the lampshade 16.

FIG. 2 is a schematic perspective view of the lighting assembly in FIG. 1 without a lampshade. Referring to FIG. 2, in some embodiments, the bracket 12 includes a protruding portion 38 located on an inner side, and a distance is provided between the protruding portion 38 and the end 36 of the bracket side wall 34.

In this way, mold forming may be facilitated and the shape of the protruding portion 38 may be prevented from affecting an optical uniformity of the light outgoing portion 20 and causing an undesired shadow. The protruding portion 38 may protrude inwardly from the bracket side wall 34.

The bracket 12 may be in the shape of a long box with one side open. There may be a plurality of protruding portions 38, which are distributed at intervals on two opposite bracket side walls 34 in the length direction.

There may be a plurality of lenses 26, which protrude at intervals on the mounting wall 28 between the bracket side walls 34.

There may be a plurality of light emitting devices 24, which may correspond to the lenses 26 one to one.

FIG. 3 is another schematic structural diagram of the lighting assembly in FIG. 1. Referring to FIG. 3, in some embodiments, a minimum distance D between the protruding portion 38 and the light outgoing portion 20 is not less than 6 millimeters.

In this way, the shape of the protruding portion 38 may be prevented from affecting the optical uniformity of the light outgoing portion 20 and causing the undesired shadow.

Numerical values herein may include values within an error range in measurement, calculation, or the like. The error range may be plus or minus five percent. For example, 6 millimeters may include 5.7 millimeters, 5.9 millimeters, 6 millimeters, 6.2 millimeters, 6.3 millimeters, or the like. The protruding portion 38 may extend diagonally between the mounting wall 28 and the bracket side wall 34. The minimum distance D between the protruding portion 38 and the light outgoing portion 20 may be a straight line distance between a position on the protruding portion 38 closest to the light outgoing portion 20 and the light outgoing portion 20. There may be a smooth transition at a connection part between the protruding portion 38 and the bracket side wall 34.

In this way, a locking structure may be arranged on the bracket 12, but there is no locking structure on the lampshade 16, which avoids an optical defect of the locking structure formed at the light outgoing portion 20. In addition, from the light outgoing portion 20, the light emitting device 24 or another optical abnormal point is invisible, and a molded surface is uniform and smooth, which is convenient for emitting light uniformly.

The lampshade 16 may be in the shape of a long box cover with one side open corresponding to the bracket 12. There may be a plurality of locking holes 40 which may be separately arranged in rows at intervals on two opposite lampshade side walls 32 in the length direction, to match a plurality of locking snaps 41 on outer surfaces of the corresponding bracket side walls 34, so that the lampshade 16 may be snap-connected to the bracket 12 at a plurality of positions, which is steady and reliable.

The length and width of the circuit board 22 may be less than those of the bracket 12. The length and width of the mounting groove 30 may be greater than or equal to those of the circuit board 22. Correspondingly, the length and width of the mounting groove 30 may be less than those of the bracket 12. The depth of the mounting groove 30 may be greater than or equal to the thickness of the circuit board 22. The circuit board 22 may be embedded in the mounting groove 30.

Still referring to FIG. 3, in some embodiments, the bracket 12 includes a mounting wall 28 for mounting the light emitting device 24, a slanted wall 58 extending from the mounting wall 28 to the lampshade 16, and a bracket side wall 34 extending from the slanted wall 58 and received in the lampshade 16.

In this way, the light emitted by the light emitting device 24 may be reflected and scattered by the slanted wall 58 and the bracket side wall 34 after being refracted by a lens 26, so as to increase the light mixing distance, reduce the thickness, and improve the light emitting uniformity to uniformly emit light with a small thickness. The matching between the slanted wall 58 and the bracket side wall 34 or the like may control a light angle.

In some embodiments, the lampshade 16 includes a lampshade side wall 32 combined with the bracket side wall 34 and the light outgoing portion 20 connected to the lampshade side wall 32, to define a space 18 together with the bracket 12.

The locking portions 90 may extend along the length of the bracket 12 and the longitudinal direction L from both sides of the bracket 12 away from the lampshade 16, and are arranged in two rows. The number of locking portions 90 arranged on one side of the bracket 12 and the number of locking portions 90 arranged on the other side of the bracket 12 may be different, for example, 3 and 4 respectively. Each of the locking portions 90 on one side of the bracket 12 may correspond to an interval between two adjacent locking portions 90 on the other side of the bracket 12. The locking portions are staggered along the width of the bracket 12 and the transverse direction H.

Still referring to FIG. 9, in some embodiments, the circuit board 22 faces a bottom wall 94 of the accommodating groove 86.

In this way, the thickness of the lighting assembly 10 may be smaller and the space requirement on the household appliance 80 may be lower.

There are no other structures between the circuit board 22 and the accommodating groove 86, to reduce the thickness of the lighting assembly 10 and lower a depth requirement on the accommodating groove 86.

The various specific implementations described above and shown in the accompanying drawings are only used to illustrate the present invention, but are not all of the present invention. Any variation made by a person of ordinary skill in the art to the present invention within the scope of the basic technical concept of the present invention shall fall within the protection scope of the present invention.
