Description

Technical Field

[0001] This disclosure relates to the field of home appliance technology, and in particular to a surface light source assembly and a refrigerator. Background Technology

[0002] Refrigerators are indispensable household appliances in people's daily lives. To facilitate users in accessing items inside the refrigerator, lighting fixtures are usually installed in the refrigerator's cooling compartment. For example, a surface light source is installed at the back of the cooling compartment and fixed to the refrigerator's air duct cover to illuminate the cooling compartment.

[0003] However, in related technologies, surface light sources and duct covers are often assembled and fixed by opening screw holes and installing screws, resulting in low assembly efficiency and high cost for surface light sources and duct covers. Utility Model Content

[0004] In view of this, the present disclosure provides a surface light source assembly and a refrigerator, which can improve assembly efficiency and save costs.

[0005] Specifically, this disclosure is achieved through the following technical solution:

[0006] According to a first aspect of the present disclosure, a surface light source assembly is provided, including an air duct cover and a surface light source component. One of the air duct cover and the surface light source component is provided with at least one first mounting hole, and the other is provided with at least one first buckle. The first mounting hole and the first buckle are in one-to-one correspondence. The first mounting hole is provided with a sliding part and a fixing part communicating with the sliding part. The first buckle can move along the sliding part to the fixing part within the first mounting hole to fix the air duct cover and the surface light source component.

[0007] According to a second aspect of the present disclosure, a refrigerator is provided, including a cabinet and the aforementioned surface light source assembly. The cabinet has a refrigeration compartment and an inner liner disposed in the refrigeration compartment. An air duct cover is connected to the inner liner, and the surface light source assembly is used to illuminate the refrigeration compartment.

[0008] The technical solutions provided by the embodiments of this disclosure have at least the following beneficial effects:

[0009] The surface light source assembly disclosed herein features a mating structure between the surface light source component and the duct cover plate, comprising a first snap-fit ​​and a first mounting hole. The first snap-fit ​​is inserted into the first mounting hole and moved from a sliding part to a fixed part, thereby limiting its position within the fixed part and achieving assembly and fixation of the surface light source component and the duct cover plate. This surface light source assembly eliminates the need for additional screw holes and assembly screws, enabling screwless installation, thus improving installation efficiency and reducing costs.

[0010] Understandably, the surface light source assembly provided in this disclosure can be applied to refrigerators, thereby improving refrigerator assembly efficiency and saving production costs.

[0011] Furthermore, the surface light source assembly provided in this disclosure is not only suitable for refrigerators, but also for other devices that require surface light source installation; this disclosure does not impose any limitations.

[0012] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this disclosure. Attached Figure Description

Detailed Implementation

[0026] The technical solutions in the embodiments (or "implementations") of this disclosure will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0027] If any terms relating to directional indications or positional relationships are used in the embodiments of this disclosure (e.g., up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, height, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movements between components in a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications or positional relationships will also change accordingly.

[0028] Refrigerators are indispensable household appliances in people's daily lives. To facilitate users in accessing items inside the refrigerator, the refrigerator's cooling compartment is usually equipped with lighting fixtures. For example, surface light sources are LED-based lighting fixtures that can be installed in the refrigerator's cooling compartment for illumination. Typically, surface light sources are located at the back of the cooling compartment and can be fixed to the refrigerator's air duct cover.

[0029] However, in related technologies, surface light sources and duct covers are often fixed together by drilling screw holes and installing screws. As a result, the larger the size of the surface light source and duct cover, the more screw holes and screws are required, leading to long assembly times, low efficiency, and high costs.

[0030] Therefore, this disclosure provides a surface light source assembly that eliminates the need for drilling screw holes and fixing screws during the assembly of the surface light source and the air duct cover in a refrigerator, thereby improving assembly efficiency and saving costs.

[0031] To better understand the surface light source assembly 10 provided in this application, a refrigerator 1 in which the surface light source assembly 10 is applied is described.

[0032] like Figure 1As shown, this application provides a refrigerator 1, including a cabinet 20 and a surface light source assembly 10. The cabinet 20 has a refrigeration compartment 21 and an inner liner 22 disposed in the refrigeration compartment 21. The surface light source assembly 10 includes an air duct cover 11 installed in the inner liner 22 and a surface light source element 12 installed in the air duct cover 11. The surface light source element 12 is used to illuminate the refrigeration compartment 21.

[0033] It should be noted that the refrigeration compartment 21 includes multiple compartments such as a freezer compartment, a refrigerator compartment, and a variable temperature compartment, and this disclosure does not limit this. The refrigerator 1 also includes a door (not shown in the drawings) for opening or closing the refrigeration compartment 21. The air duct cover 11 is used to cooperate with the refrigeration system of the refrigerator 1 to introduce cold air into the air duct of the refrigerator 1 and blow it from the air outlet of the air duct to various parts of the refrigeration compartment 21, thereby reducing the temperature inside the refrigeration compartment 21. The surface light source 12 may include an LED surface light source, which can illuminate the refrigeration compartment 21 according to set requirements (such as when the user opens the door), making it easier for the user to retrieve the stored items inside the refrigeration compartment 21. As an example, along... Figure 1 In the front-to-back direction, the air duct cover 11 has a front facing forward and a back facing backward. The back of the air duct cover 11 is connected to the inner liner 22 of the refrigerator 1, and the surface light source 12 is installed on the front of the air duct cover 11 to illuminate the refrigeration compartment 21.

[0034] The surface light source assembly 10 provided in this disclosure will now be described in conjunction with the accompanying drawings.

[0035] See Figures 2 to 5 , Figure 2 This is a schematic diagram of the surface light source assembly 10 in an exploded state according to an embodiment. Figure 3 for Figure 2 Enlarged view of point a in the middle. Figure 4 for Figure 2 The diagram shows the structure of the surface light source assembly 10 in a fixed state. Figure 5 for Figure 4 Enlarged view at point b. The surface light source assembly 10 provided in this disclosure includes a duct cover 11 and a surface light source component 12. One of the duct cover 11 and the surface light source component 12 is provided with at least one first mounting hole 13, and the other is provided with at least one first snap fastener 14. The first mounting hole 13 and the first snap fastener 14 are correspondingly engaged. The first mounting hole 13 is provided with a sliding part 131 and a fixing part 132 communicating with the sliding part 131. The first snap fastener 14 can move along the sliding part 131 to the fixing part 132 within the first mounting hole 13 to fix the duct cover 11 and the surface light source component 12.

[0036] It should be noted that the assembly and fixation of the surface light source component 12 and the air duct cover plate 11 can be achieved through the corresponding engagement of the first buckle 14 and the first mounting hole 13. Specifically, during the assembly process of the surface light source component 12 and the air duct cover plate 11, the first mounting hole 13 and the first buckle 14 are in a specific position. Figure 3 In the indicated state, the first latch 14 can enter the first mounting hole 13 through the sliding part 131, and move the first latch 14 along the sliding part 131 to the fixing part 132 within the first mounting hole 13, so that the first latch 14 can be limited in the fixing part 132, forming Figure 5 As shown in the figure, the surface light source 12 and the air duct cover 11 are assembled and fixed.

[0037] Understandably, the limiting between the first buckle 14 and the fixing part 132 can be achieved through various methods such as snap-fit ​​fixing, insertion fixing, compression fixing, friction fixing, or magnetic fixing, and this disclosure does not impose any limitations. In addition, the first mounting hole 13 can be a square hole, a strip hole, an elliptical hole, or an irregular hole, and the first buckle 14 can be set to an adaptive shape that mates with the first mounting hole 13, and this disclosure does not impose any limitations.

[0038] Therefore, the surface light source assembly 10 provided in this disclosure, by providing a cooperating structure between the surface light source component 12 and the air duct cover plate 11 with a first buckle 14 and a first mounting hole 13, allows the first buckle 14 to be inserted into the first mounting hole 13 and moved from the sliding part 131 to the fixing part 132, thereby achieving the assembly and fixation of the surface light source component 12 and the air duct cover plate 11. The surface light source assembly 10 provided in this disclosure does not require additional screw holes and assembly screws, enabling screwless installation, thereby improving installation efficiency and reducing costs.

[0039] Furthermore, when the surface light source assembly 10 is applied to the refrigerator 1, it can further improve the assembly efficiency of the refrigerator 1 and save on the production cost of the refrigerator 1. It is understood that the surface light source assembly 10 provided in this disclosure is not only applicable to the refrigerator 1, but also applicable to other equipment that requires surface light source installation, and this disclosure does not impose any limitations.

[0040] See Figure 2 In some embodiments, the surface light source 12 includes a mounting portion 121 and a light source portion 122. The mounting portion 121 has a mounting surface facing the air duct cover 11 and a light source surface opposite to the mounting surface, and the light source portion 122 is mounted on the light source surface. One of the first mounting hole 13 and the first buckle 14 may be provided in the mounting portion 121.

[0041] It should be noted that the light source 122 can be a light source such as an optical film or a lamp panel. The mounting part 121 can be a border trim strip covering the edge of the light source 122. Thus, the light source 122 and the mounting part 121 are combined to form an assembly of the surface light source 12. By providing one of the first mounting hole 13 and the first latch 14 in the mounting part 121, the light emitted from the light source 122 can be prevented from being blocked, ensuring the integrity and uniformity of the illumination of the light source 122 and reducing dark spots. As an example, along... Figure 2 In the front-to-back direction, the mounting part 121 has a light source surface facing forward and a mounting surface facing rearward. The light source part 122 can be mounted to the light source surface, and one of the first mounting hole 13 and the first buckle 14 can be provided on the mounting surface.

[0042] See Figure 2 and Figure 3 In some embodiments, the duct cover 11 has a first mounting hole 13, and the surface light source 12 has a first buckle 14. As an example, in the direction from the light source surface to the mounting surface, the first mounting hole 13 is recessed in the duct cover 11, and the first buckle 14 is protruding from the mounting surface.

[0043] With this configuration, after the surface light source 12 is assembled with the air duct cover 11, along... Figure 2 As shown in the front-to-back direction, the first buckle 14 passes through the first mounting hole 13 from front to back, so that the mating structure between the air duct cover 11 and the surface light source 12 is completed on the mounting surface side of the mounting part 121, and the light source surface of the mounting part 121 facing the refrigerator 1 cooling compartment 21 is clean and smooth, with good aesthetics.

[0044] See Figure 2 and Figure 3 In some embodiments, to facilitate the assembly of the surface light source assembly 10, the sliding portion 131 and the fixing portion 132 of the first mounting hole 13 are connected along the length direction of the air duct cover plate 11. Furthermore, in the width direction of the air duct cover plate 11, the width of the sliding portion 131 is set to be greater than the width of the fixing portion 132.

[0045] It should be noted that when assembling the surface light source assembly 10, the operator can slide the surface light source component 12 from top to bottom along the length of the air duct cover plate 11, so that the first latch 14 moves from the sliding part 131 to the fixing part 132 within the first mounting hole 13. This arrangement allows the operator to use the weight of the surface light source component 12 to move it to the fixing part 132 for positioning, facilitating assembly and reducing effort. Simultaneously, to facilitate the first latch 14 entering the first mounting hole 13 and being fixed within the fixing part 132, the width of the sliding part 131 is set to be greater than the width of the fixing part 132. As an example, the sliding part 131, as the wider portion of the first mounting hole 13, is used for the first latch 14 to enter the first mounting hole 13, and its width can be set to 4mm to 6mm. The fixing part 132, as the narrower portion of the first mounting hole 13, is used for the first latch 14 to be fixed within the first mounting hole 13, and its width can be set to 2mm to 3mm. The widths of the sliding part 131 and the fixed part 132 can also be set according to actual usage requirements, which will not be elaborated in this disclosure.

[0046] See Figures 4 to 6 In some embodiments, to facilitate the fixing of the first buckle 14 to the first mounting hole 13, the first buckle 14 includes a connecting portion 141 connected to the mounting surface and a fastening portion 142 connected to the connecting portion 141. The fastening portion 142 passes through the first mounting hole 13 in the direction from the light source surface to the mounting surface and is inclined relative to the connecting portion 141. When the connecting portion 141 moves along the sliding portion 131 to the fixing portion 132, the portion of the fastening portion 142 extending out of the first mounting hole 13 can be pressed and fixed against the air duct cover 11.

[0047] It should be noted that the connecting portion 141 of the first buckle 14 can extend along the depth direction of the first mounting hole 13, and the fastening portion 142 is connected to the connecting portion 141 and extends out from the first mounting hole 13, forming a bent portion at an angle. For example, as Figure 6 The first buckle 14, as shown, can form a slot with the mounting portion 121 of the surface light source 12. When the first buckle 14 moves to the fixing portion 132, part of the hole wall of the first mounting hole 13 can engage with the slot formed by the first buckle 14. The engaging portion 142 of the first buckle 14 presses against and fixes the air duct cover 11, thereby realizing the assembly and fixation of the surface light source 12 and the air duct cover 11.

[0048] See Figure 6 In some embodiments, to facilitate the engagement of the first buckle 14 with the first mounting hole 13, at least one of the hole wall of the first mounting hole 13 and the outer wall of the first buckle 14 is provided with a guide structure 18.

[0049] As an example, the inner wall of the first mounting hole 13 is provided with a first chamfer, which forms a guide structure 18. Thus, the first latch 14 can enter the first mounting hole 13 through the first chamfer. Correspondingly, for the first latch 14, the outer wall of the end of the latching part 142 used to connect with the connecting part 141 can also be provided with a second chamfer, and the outer wall of the end of the latching part 142 used to press against the duct cover 11 can also be provided with a third chamfer, to cooperate and guide with the first chamfer in the first mounting hole 13. Thus, the guide structure 18 facilitates the entry of the first latch 14 into the first mounting hole 13. It is understood that the dimensions of each chamfer are not limited in this disclosure and can be processed according to actual usage requirements.

[0050] See you later Figure 5 In some embodiments, when the first buckle 14 is in the fixing part 132, the first buckle 14 and the fixing part 132 are configured to be in clearance fit along the length direction of the air duct cover plate 11 and / or along the width direction of the air duct cover plate 11. The first buckle 14 and the first mounting hole 13 can be used to fix the surface light source 12 in the thickness direction of the air duct cover plate 11.

[0051] It should be noted that when the surface light source assembly 10 is used in the refrigerator 1, the large temperature difference between the interior and exterior of the refrigeration compartment 21 poses a risk of dimensional deformation due to thermal expansion and contraction between the first latch 14 and the first mounting hole 13 between the surface light source component 12 and the air duct cover 11. Therefore, setting the first latch 14 and the first mounting hole 13 to a clearance fit allows for dimensional deformation, prevents over-positioning between the first latch 14 and the first mounting hole 13, and also prevents deformation from squeezing the light source part 122, thus affecting the lighting effect.

[0052] In addition, when the surface light source assembly 10 is suitable for assembling equipment with small temperature differences, the first mounting hole 13 and the first buckle 14 are set to a clearance fit, which can also avoid assembly problems caused by processing errors, thereby reducing the processing difficulty.

[0053] As an example, when the first buckle 14 and the first mounting hole 13 are in clearance fit, a first gap 143 is provided between the first buckle 14 and the inner wall of the fixing part 132 in the direction from the sliding part 131 to the fixing part 132. The range of the first gap 143 is set to 0.7mm to 1mm, and this disclosure does not limit it.

[0054] See Figure 7 and Figure 8 In some embodiments, in order to facilitate the first buckle 14 and the first mounting hole 13 to form a clearance fit, the duct cover 11 is also provided with a positioning structure 15 spaced apart from the first mounting hole 13, and the surface light source 12 abuts against the positioning structure 15 so that the first buckle 14 and the fixing part 132 form a clearance fit.

[0055] It should be noted that when assembling the surface light source 12 and the duct cover 11, the surface light source 12 moves from top to bottom along the length of the duct cover 11, and the first latch 14 on the surface light source 12 enters the first mounting hole 13. The surface light source 12 continues to slide along the duct cover 11 until the lower end of the surface light source 12 abuts against the positioning structure 15 on the duct cover 11. Then, the first latch 14 moves into place in the first mounting hole 13, that is, the first latch 14 moves from the sliding part 131 to the fixing part 132, and a first gap 143 is formed between the lower end of the first latch 14 and the interior of the fixing part 132.

[0056] Understandably, a groove is provided at the lower end of the duct cover 11, which can serve as a positioning structure 15. Correspondingly, a boss is provided at the lower end of the duct cover 11, which can also serve as a positioning structure 15. This disclosure does not limit the specific configuration of the positioning structure 15.

[0057] Furthermore, in some embodiments, when the first buckle 14 and the first mounting hole 13 are in clearance fit, a gap may also be provided between the first buckle 14 and the inner wall of the fixing part 132 along the width direction of the air duct cover 11. In this way, when the first buckle 14 and the first mounting hole 13 are in clearance fit, the air duct cover 11 and the surface light source 12 can be fixed along the thickness direction of the air duct cover 11 by the pressing of the buckling part 142 of the first buckle 14 against the air duct cover 11.

[0058] See Figure 7 and Figure 9 In some embodiments, to facilitate fixing the surface light source 12 along the length of the duct cover 11, one of the duct cover 11 and the surface light source 12 is provided with a limiting structure, and the other is provided with a mating structure that cooperates with the limiting structure. When the first buckle 14 moves along the sliding part 131 to the fixing part 132, the limiting structure and the mating structure cooperate accordingly.

[0059] With this configuration, the first buckle 14 and the first mounting hole 13 can fix the surface light source 12 in the thickness direction of the air duct cover 11. Furthermore, the limiting structure and the mating structure can also fix the surface light source 12 in the length direction of the air duct cover 11, so as to achieve the assembly and fixation between the air duct cover 11 and the surface light source 12.

[0060] Understandably, the limiting structure and the fixing structure can be achieved through various methods such as fastening, insertion, compression, friction, or magnetic attraction, and this disclosure does not impose any restrictions.

[0061] As an example, the limiting structure includes a second mounting hole 16, and the mating structure includes a second latch 17. The first mounting hole 13 and the second latch 17 are respectively spaced apart on the duct cover 11, and the second mounting hole 16 and the first latch 14 are respectively spaced apart on the surface light source component 12. The second latch 17 is elastic; when the first latch 14 is in the sliding portion 131, the second latch 17 abuts against the surface light source component 12; when the first latch 14 is in the fixed portion 132, the second latch 17 springs back and engages with the second mounting hole 16.

[0062] With this configuration, during the installation of the surface light source 12 onto the duct cover 11, when the first latch 14 enters the first mounting hole 13 and is in the sliding part 131, the second latch 17 on the duct cover 11 is in a pressing state with the surface light source 12, so the second latch 17 will not hinder the surface light source 12 from continuing to move. When the first latch 14 moves from the sliding part 131 to the fixing part 132, the first latch 14 abuts against the duct cover 11, fixing the surface light source 12 in the thickness direction of the duct cover 11. At this time, the second latch 17 springs back and can enter the second mounting hole 16 of the surface light source 12, fixing the surface light source 12 in the length direction of the duct cover 11. Thus, the cooperation between the first latch 14 and the first mounting hole 13, and the cooperation between the second latch 17 and the second mounting hole 16, can meet the assembly and fixing requirements of the surface light source 12 and the duct cover 11.

[0063] Understandably, the surface light source 12 includes a light source portion 122 and a mounting portion 121 that surrounds the edge of the light source portion 122. The mounting portion 121 has a rearward mounting surface and a forward light source surface, and the light source portion 122 is disposed on the light source surface. The second mounting hole 16 and the first snap-fit ​​14 can be respectively and spaced apart on the mounting surface of the mounting portion 121. This arrangement is equivalent to opening and assembling the surface light source 12 on its rear side, which satisfies the assembly requirements of the surface light source 12 without affecting the appearance and light distribution of the surface light source 12 on the illumination side.

[0064] See Figure 9 In some embodiments, to prevent the second latch 17 from scratching the light source part 122, a second gap 171 is provided between the portion of the second latch 17 that extends into the second mounting hole 16 and the light source part 122 in the direction from the mounting surface to the light source surface.

[0065] It should be noted that, to facilitate the opening of the second mounting hole 16 in the mounting portion 121, the second mounting hole 16 can be configured as a through hole penetrating the mounting portion 121. Thus, when the second latch 17 springs back to the second mounting hole 16, a gap 171 forms between the second latch 17 and the light source portion 122, preventing the second latch 17 from scratching the light source portion 122, which can be an optical film. Understandably, the second gap 171 is not less than 0.2 mm. For example, the second gap 171 can be equal to 0.2 mm, and the specific size of the second gap 171 can be set according to usage requirements; this disclosure does not impose any limitations.

[0066] Of course, in other embodiments, the second mounting hole 16 may also be a blind hole that does not penetrate the mounting portion 121, thereby preventing the second snap 17 from rebounding and scratching the light source portion 122. This disclosure does not impose any limitations.

[0067] See you later Figure 2 and Figure 4 In some embodiments, in order to improve the connection reliability of the surface light source assembly 10, at least one first mounting hole 13 is provided on each of the opposite sides of the air duct cover 11 along the width direction, and at least one first buckle 14 is also provided on each of the opposite sides of the surface light source component 12.

[0068] Understandably, the length direction of the duct cover 11 is along Figure 2 The vertical orientation is shown. The width direction of the duct cover 11 is along... Figure 2 The arrangement is shown in the left-right direction. At least one first mounting hole 13 can be provided on each of the left and right sides of the duct cover 11, and these first mounting holes 13 can be spaced apart along the length of the duct cover 11. Correspondingly, at least one corresponding first latch 14 can be provided on each of the left and right sides of the surface light source 12, and these first latches 14 can be spaced apart along the length of the duct cover 11. Thus, by the one-to-one correspondence between the multiple first mounting holes 13 and the multiple first latches 14, the connection reliability between the surface light source 12 and the duct cover 11 can be improved.

[0069] Furthermore, the second mounting hole 16 and the first buckle 14 can be spaced apart on the surface light source 12 along the length direction of the air duct cover 11. The first mounting hole 13 and the second buckle 17 can be spaced apart on the air duct cover 11 along the length direction of the air duct cover 11.

[0070] See Figure 2 and Figure 3In some embodiments, for the surface light source assembly 10 provided in this disclosure, the first mounting hole 13 is disposed on the edge side of the air duct cover plate 11, and a gap is left between the hole wall of the first mounting hole 13 and the edge of the air duct cover plate 11. This is equivalent to the hole wall of the first mounting hole 13 being a closed curve, and the two side edges of the air duct cover plate 11 being straight lines. In this way, the edge side of the air duct cover plate 11 can also be used for applying adhesive or tape for bonding the glass panel. Thus, the air duct cover plate 11 of this disclosure can meet both the assembly requirements of the surface light source component 12 and the installation requirements of the glass panel, improving the versatility of the air duct cover plate 11 and eliminating the need to create separate air duct cover plates 11 for the surface light source component 12 and the glass panel.

[0071] In addition, see Figure 5 The first buckle 14 is disposed on the edge side of the surface light source 12, and the fastening part 142 of the first buckle 14 is oriented relative to the connecting part 141. Figure 5 The surface light source assembly 10 is tilted to the right. This design satisfies the limiting requirements of the first buckle 14 and the first mounting hole 13, while also avoiding the adhesive tape applied when the air duct cover 11 is bonded to the glass panel.
