Technical Field
[0001] This application relates to the field of home appliance technology, and in particular to an air duct device and a refrigerator. Background Technology
[0002] Refrigerators are indispensable household appliances in people's daily lives. In related technologies, to facilitate users in accessing items inside the refrigerator's cooling compartment, the air duct system inside the cooling compartment is usually equipped with a surface light source. As a type of lighting fixture, the surface light source illuminates the cooling compartment when the user opens the refrigerator door. However, in related technologies, disassembling the surface light source often causes damage to the entire air duct system, leading to increased maintenance costs and a poor user experience. Utility Model Content
[0003] In view of this, this application provides an air duct device and a refrigerator, which allows the surface light source assembly to be flexibly installed and removed from the air duct device, thereby saving maintenance costs and improving the user experience.
[0004] Specifically, this application is implemented through the following technical solution:
[0005] According to a first aspect of the embodiments of this application, an air duct device is provided, including an air duct assembly and a surface light source assembly. The air duct assembly has a mounting side and a back side disposed opposite to each other along the thickness direction of the air duct device, and the back side has a clearance groove and a power supply terminal located in the clearance groove. The surface light source assembly includes a light source element, a connecting wire connected to the light source element, and a wiring terminal connected to the connecting wire. The light source element is detachably connected to the air duct assembly and is located on the mounting side, and the wiring terminal is detachably connected to the power supply terminal.
[0006] In some embodiments, the duct assembly includes a duct cover and a duct foam connected to the duct cover. The duct cover is located on the mounting side and is detachably connected to the light source, while the duct foam is located on the back side and has a clearance groove.
[0007] In some embodiments, the duct cover has a top and a bottom that are disposed opposite each other along the height direction of the duct device, one end of the connecting wire is connected to the side of the light source near the top, the other end of the connecting wire is connected to the terminal block, and a clearance groove is disposed on the side of the duct foam near the top.
[0008] In some embodiments, the duct cover plate further includes a first side and a second side disposed opposite to each other along the width direction of the duct device. At least one of the first side, the second side, and the top is provided with a connecting structure. The light source part is provided with a mating structure that corresponds one-to-one with the connecting structure. The mating structure and the connecting structure are detachably connected. When the top is provided with a connecting structure, the clearance groove and the connecting structure are spaced apart along the direction from the first side to the second side.
[0009] In some embodiments, the duct device further includes a terminal holder, which is disposed on the duct cover and located in the clearance groove, and a power supply terminal is installed on the terminal holder, and / or the wiring terminal is detachably connected to the terminal holder.
[0010] In some embodiments, the clearance groove has a notch opening to the top and a groove bottom opposite to the notch, and there is an installation gap between the terminal fixing seat and the groove bottom. The wiring terminal and the power supply terminal are inserted along the height direction of the air duct device.
[0011] In some embodiments, the power supply terminal is connected to the top side of the terminal holder, and the wiring terminal can be plugged into the power supply terminal in the direction from bottom to top, and the wiring terminal can be disconnected from the power supply terminal in the direction from top to bottom.
[0012] In some embodiments, the air duct device further includes a power supply line embedded between the air duct cover plate and the air duct foam. At least one of the air duct foam and the air duct cover plate is provided with a wiring groove communicating with the clearance groove. The power supply line is disposed in the wiring groove. One end of the power supply line is connected to a power supply terminal, and the other end of the power supply line is used to connect to the main control board of the refrigerator.
[0013] In some embodiments, the ductwork device further includes a harness limiting seat located within a clearance groove, through which at least one of the power supply line and the connecting line passes.
[0014] According to a second aspect of the present application, a refrigerator is provided, including a cabinet and the aforementioned air duct device. The cabinet has a refrigeration compartment and an inner liner located in the refrigeration compartment. The air duct assembly is detachably connected to the inner liner, and the surface light source assembly is used to illuminate the refrigeration compartment.
[0015] The technical solutions provided by the embodiments of this application have at least the following beneficial effects:
[0016] The air duct device provided in this application can be installed in refrigeration equipment such as refrigerators, freezers, and crisper cabinets, and this application does not impose any limitations. The air duct assembly has an installation side and a back side arranged opposite to each other along the thickness direction of the air duct assembly. The back side of the air duct assembly can face the back inner liner of the refrigerator, and the installation side of the air duct assembly can face the refrigeration compartment. With this arrangement, installing the surface light source assembly on the installation side of the air duct assembly allows the surface light source assembly to be located inside the refrigeration compartment of the refrigerator to illuminate the refrigeration compartment. When the surface light source assembly is connected to the air duct assembly, the light source can be connected to the air duct assembly by a detachable connection method such as plugging, snapping, bolting, or magnetic attraction to fix the light source. At the same time, the connecting wire is used to connect the light source to the terminal block, and the terminal block is used to detachably connect to the power supply terminal in the clearance groove. The power supply terminal can be used to connect to the main control board of the refrigerator or other external power sources, so that the connection between the terminal block and the power supply terminal can connect the connection circuit between the light source and the power source, so that the light source can light up normally.
[0017] Thus, when detaching the surface light source assembly and the air duct assembly, this application only requires separating the wiring terminals and power supply terminals connected in the clearance groove to disconnect the circuit connection structure between the surface light source assembly and the air duct assembly. Then, by separating the detachable connection structures such as plug-in, snap-fit, bolt fixing, or magnetic attraction between the light source and the air duct assembly, the mechanical connection structure between the surface light source assembly and the air duct assembly can be disconnected. This allows the surface light source assembly and the air duct assembly to be completely separated without damaging the internal structure of the air duct assembly. This allows the air duct assembly to continue to be used after the surface light source assembly is removed, thereby saving maintenance costs and improving the user experience.
[0018] Therefore, the air duct device provided in this application allows for flexible installation and removal of the surface light source assembly from the air duct device without damaging the air duct device, thereby saving maintenance costs and improving the user experience. When the air duct device provided in this application is applied to a refrigerator, the nominal volume of the refrigerator can also be increased by disassembling the surface light source assembly.
[0019] It is understood that the air duct device provided in this application is not limited to use in refrigerators, but can also be used in any household appliance that requires the disassembly and assembly of surface light sources, such as freezers or refrigeration cabinets. This application makes no restrictions.

Detailed Implementation
[0033] The technical solutions in the embodiments (or "implementations") of this application 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.
[0034] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as 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 attached figures). If the specific posture changes, the directional indications or positional relationships will also change accordingly.
[0035] Refrigerators are indispensable household appliances in people's daily lives. In related technologies, to facilitate users in retrieving items from the refrigerator's cooling compartment, the air duct system inside the cooling compartment is usually equipped with a surface light source. As a type of lighting fixture, the surface light source illuminates the cooling compartment when the user opens the refrigerator door.
[0036] The related ductwork device includes a duct cover and a foam layer fixed to the cover. A surface light source is fixedly connected to the cover for illuminating the cooling room. The surface light source's wiring is typically embedded entirely between the cover and the foam layer. However, disassembling the surface light source often requires breaking the foam layer to remove the embedded wiring, completely separating the light source from the ductwork. This damages the ductwork during removal, increasing maintenance costs and resulting in a poor user experience.
[0037] Therefore, this application provides a duct device that allows the surface light source component to be flexibly installed and removed from the duct device without damaging the foam layer of the duct device, thereby saving maintenance costs and improving the user experience.
[0038] It is understood that the air duct device provided in this application is not limited to use in refrigerators, but can also be used in any household appliance that requires the disassembly and assembly of surface light sources, such as freezers or refrigeration cabinets. This application makes no restrictions.
[0039] The air duct device provided in this application will now be described in conjunction with the accompanying drawings.
[0040] See Figures 1 to 3 This application provides an air duct device 10, which includes an air duct assembly 11 and a surface light source assembly 12. The air duct assembly 11 has a mounting side 11a and a back side 11b disposed opposite to each other along the thickness direction of the air duct device 10. The back side 11b has a clearance groove 113 and a power supply terminal 114 located in the clearance groove 113. The surface light source assembly 12 includes a light source element 121, a connecting wire 122 connected to the light source element 121, and a wiring terminal 123 connected to the connecting wire 122. The light source element 121 is detachably connected to the air duct assembly 11 and is located on the mounting side 11a. The wiring terminal 123 is detachably connected to the power supply terminal 114.
[0041] It should be noted that the air duct device 10 provided in this application can be installed in refrigeration equipment such as refrigerators 1, freezers, and crisper cabinets, and this application does not impose any restrictions. Taking the air duct device 10 being detachably installed in refrigerator 1 as an example, the air duct assembly 11 can be detachably connected to the inner liner 22 of refrigerator 1 to cooperate with the fan inside refrigerator 1 to deliver airflow to the refrigeration compartment 21, and the surface light source assembly 12 can be used to illuminate the refrigeration compartment 21 to facilitate users in taking and placing items in the refrigeration compartment 21.
[0042] Specifically, the air duct assembly 11 has a mounting side 11a and a back side 11b disposed opposite to each other along the thickness direction of the air duct device 10. It can be understood that the thickness direction of the air duct device 10 can be arranged in the front-back direction shown in the figure. The back side 11b of the air duct assembly 11 can face the back liner 22 of the refrigerator 1, and the mounting side 11a of the air duct assembly 11 can face the cooling compartment 21. With this arrangement, mounting the surface light source assembly 12 on the mounting side 11a of the air duct assembly 11 allows the surface light source assembly 12 to be positioned within the cooling compartment 21 of the refrigerator 1 to illuminate the cooling compartment 21.
[0043] Understandably, mounting the surface light source assembly 12 to the air duct assembly 11 includes both mechanical and electrical connections. The mechanical connections are used to secure the surface light source assembly 12, while the electrical connections are used to power the surface light source assembly 12 so that it can illuminate.
[0044] The surface light source assembly 12 provided in this application includes a light source element 121, a connecting wire 122 connected to the light source element 121, and a terminal block 123 connected to the connecting wire 122. The air duct assembly 11 provided in this application has a clearance groove 113 on its back side 11b and a power supply terminal 114 located within the clearance groove 113. When the surface light source assembly 12 is connected to the air duct assembly 11, the light source element 121 can be connected to the air duct assembly 11 via a detachable connection method such as plugging, snapping, bolting, or magnetic attraction to fix the light source element 121. Simultaneously, the connecting wire 122 is used to connect the light source element 121 to the terminal block 123, and the terminal block 123 is used for detachable connection to the power supply terminal 114 within the clearance groove 113. The power supply terminal 114 can be used to connect to the main control board 30 of the refrigerator 1 or other external power sources, enabling the connection between the terminal block 123 and the power supply terminal 114 to establish a connection circuit between the light source element 121 and the power source, allowing the light source element 121 to light up normally.
[0045] Understandably, the clearance groove 113 provides clearance space for the detachable connection of the wiring terminal 123 and the power supply terminal 114, allowing the power supply terminal 114 to be exposed outside the air duct assembly 11, so that the wiring terminal 123 and the power supply terminal 114 can be detachably connected outside the air duct assembly 11. At the same time, by setting the clearance groove 113 on the back side 11b of the air duct assembly 11, it can avoid interference with the detachable installation of the light source 121 on the mounting side 11a of the air duct assembly 11, and it can also hide the wiring terminal 123 and the power supply terminal 114 behind the air duct assembly 11, so that the air duct device 10 can be installed in the refrigerator 1 to ensure the neatness and aesthetics of the refrigeration compartment 21.
[0046] Thus, when the surface light source assembly 12 and the air duct assembly 11 are disconnected, this application only needs to separate the wiring terminal 123 and the power supply terminal 114 connected in the clearance groove 113 to disconnect the circuit connection structure 13 between the surface light source assembly 12 and the air duct assembly 11. Then, the detachable connection structure 13 between the light source component 121 and the air duct assembly 11, such as the plug-in, snap-fit, bolt fixing or magnetic attraction, can be separated to disconnect the mechanical connection structure 13 between the surface light source assembly 12 and the air duct assembly 11. This allows the surface light source assembly 12 and the air duct assembly 11 to be completely separated without damaging the internal structure of the air duct assembly 11. This allows the air duct assembly 11 to continue to be used after the surface light source assembly 12 is removed, thereby saving maintenance costs and improving the user experience.
[0047] See Figures 1 to 3 In some embodiments, the air duct assembly 11 includes an air duct cover plate 111 and an air duct foam 112 connected to the air duct cover plate 111. The air duct cover plate 111 is located on the mounting side 11a and is detachably connected to the light source component 121. The air duct foam 112 is located on the back side 11b and is provided with a clearance groove 113.
[0048] It should be noted that the air duct foam 112 is located on the back side 11b of the air duct device 10, facing the inner liner 22 of the refrigerator 1. The air duct foam 112 has at least one air passage 119, which can be used to cooperate with the fan inside the refrigerator 1 to deliver cooling capacity to the cooling compartment 21. The air duct cover 111 is located on the mounting side 11a, facing the cooling compartment 21 of the refrigerator 1. The air duct cover 111 can be used to cover the air duct foam 112 and is detachably connected to the inner liner 22 of the refrigerator 1, thereby ensuring the cleanliness and aesthetics of the cooling compartment 21. At the same time, the air duct cover 111 can also support the detachment and connection of the surface light source assembly 12, so that the surface light source assembly 12 illuminates the cooling compartment 21. Thus, by directly opening a clearance groove 113 on the air duct foam 112 to accommodate the power supply terminal 114, the wiring terminal 123 and the power supply terminal 114 can be detachably connected outside the air duct assembly 11, so as to avoid damaging the air duct foam 112 and entering the interior of the air duct assembly 11 before disconnecting the surface light source assembly 12.
[0049] See Figures 1 to 3 In some embodiments, the duct cover 111 has a top 1111 and a bottom 1112 that are arranged opposite to each other along the height direction of the duct device 10. One end of the connecting wire 122 is connected to the side of the light source 121 near the top 1111, and the other end of the connecting wire 122 is connected to the terminal block 123. The clearance groove 113 is provided on the side of the duct foam 112 near the top 1111.
[0050] It should be noted that the height of the air duct device 10 can be set vertically as shown in the figure. Specifically, the top 1111 faces upwards, and the bottom 1112 faces downwards. In this way, by leading the wiring 122 of the surface light source assembly 12 out from the side of the light source unit near the top 1111, and by opening the clearance groove 113 on the side of the air duct foam 112 near the top 1111, the length of the wiring 122 of the surface light source assembly 12 can be shortened. This avoids wire entanglement and short circuits, as well as wire vibration and loosening, during the installation of the wiring terminal 123 and the power supply terminal 114, thereby ensuring reliable connection between the wiring terminal 123 and the power supply terminal 114.
[0051] See Figures 1 to 3 In some embodiments, the duct cover 111 is further provided with a first side portion 1113 and a second side portion 1114 disposed opposite to each other along the width direction of the duct device 10. At least one of the first side portion 1113, the second side portion 1114, and the top portion 1111 is provided with a connecting structure 13. The light source portion is provided with a mating structure 14 that corresponds one-to-one with the connecting structure 13. The mating structure 14 is detachably connected to the connecting structure 13. When the top portion 1111 is provided with a connecting structure 13, the clearance groove 113 and the connecting structure 13 are spaced apart along the direction from the first side portion 1113 to the second side portion 1114.
[0052] It should be noted that the width of the air duct device 10 can be set along the left-right direction in the figure. Taking the mounting side 11a facing the air duct device 10 as an example, the first side 1113 is located on the right side and the second side 1114 is located on the left side. In order to improve the connection stability between the air duct cover 111 and the light source 121, at least one of the top 1111 and the left and right sides of the air duct cover 111 can be detachably connected to the light source 121, thereby increasing the connection area between the air duct cover 111 and the light source 121 and increasing the connection reliability.
[0053] Understandably, the light source 121 includes a frame around which the lamp panel is mounted. The lamp panel includes lighting fixtures such as LED lights, fluorescent tubes, and incandescent lamps, which are not limited in this application. The frame can be used to provide a mating structure 14 for detachable connection with the duct cover 111. As an example, the mating structure 14 may include a flange protruding from the frame and multiple mounting holes provided on the flange. The connecting structure 13 may include multiple protruding shafts provided on the duct cover 111, and the detachable connection between the light source 121 and the duct cover 111 is achieved through the insertion and engagement of the protruding shafts with the mounting holes. Of course, the connecting structure 13 may also include mating holes that coincide with the mounting holes. Bolts can be installed in the mounting holes and mating holes to detachably connect the light source 121 and the duct cover 111 through bolts, which is not limited in this application. In addition, the detachable connection between the connecting structure 13 and the mating structure 14 also includes various methods such as magnetic attraction, snap-fit, and elastic compression, which will not be elaborated in this application.
[0054] Understandably, when the top 1111 of the duct cover 111 is provided with a connecting structure 13, in order to avoid the assembly interference between the wiring terminal 123 and the power supply terminal 114 and the connecting structure 13, the clearance groove 113 and the connecting structure 13 are spaced apart in the left and right directions.
[0055] See Figure 3 In some embodiments, the duct foam 112 has at least one air passage 119 on the side facing away from the duct cover plate 111, and the clearance groove 113 is spaced apart from the air passage 119. With this arrangement, the air passage 119 foam can be separated to prevent moisture carried in the air passage 119 from entering the clearance groove 113, thereby preventing the connection between the wiring terminal 123 and the power supply terminal 114 from getting damp.
[0056] See Figure 3 and Figure 4 In some embodiments, to facilitate fixing the power supply terminal 114, the air duct device 10 also includes a terminal fixing seat 115. The terminal fixing seat 115 is disposed on the air duct cover plate 111 and located in the clearance groove 113. The power supply terminal 114 is installed on the terminal fixing seat 115, and / or the wiring terminal 123 is detachably connected to the terminal fixing seat 115.
[0057] It should be noted that the terminal fixing base 115 includes a boss protruding from the air duct cover plate 111. The power supply terminal 114 can be fixed to the boss to increase the connection area between the power supply terminal 114 and the air duct cover plate 111, so that the power supply terminal 114 can be stably fixed in the clearance groove 113 for detachable connection with the wiring terminal 123. Of course, in other embodiments, the wiring terminal 123 can be detachably connected to the terminal fixing base 115, and the power supply terminal 114 can then be connected to the wiring terminal 123; this application does not impose any limitations. In other embodiments, the power supply terminal 114 can be fixedly connected to the terminal fixing base 115, and the wiring terminal 123 can be detachably connected to the terminal fixing base 115; this application does not impose any limitations.
[0058] See Figure 4 In some embodiments, the clearance groove 113 is provided with a notch 1131 opening towards the top 1111 and a groove bottom 1132 disposed opposite to the notch 1131. There is an installation gap between the terminal fixing seat 115 and the groove bottom 1132. The wiring terminal 123 and the power supply terminal 114 are inserted along the height direction of the air duct device 10.
[0059] It should be noted that the clearance groove 113 can be formed from top to bottom on the side of the air duct foam 112 near the top 1111, so that the clearance groove 113 has an upward-facing notch 1131 and a groove bottom 1132 opposite to the notch 1131. The wiring terminal 123 can enter the clearance groove 113 through the notch 1131 and connect to the power supply terminal 114. The power supply terminal 114 and the wiring terminal 123 can be detachably connected by plugging. To allow for the insertion and removal distance between the power supply terminal 114 and the wiring terminal 123, an installation gap d is provided between the terminal fixing base 115 and the groove bottom 1132 of the clearance groove 113. The installation gap d is not less than 50mm to avoid interference between the wiring terminal 123 or the power supply terminal 114 and the groove bottom 1132.
[0060] Understandably, the power supply terminal 114 can be located above the terminal holder 115, and the wiring terminal 123 can be inserted into the power supply terminal 114 from below the terminal holder 115. Alternatively, the power supply terminal 114 can be located below the terminal holder 115, and the wiring terminal 123 can be inserted into the power supply terminal 114 from above the terminal holder 115; this application does not impose any restrictions.
[0061] As an example, one of the terminal block 123 and the power supply terminal 114 is provided with a socket, and the other of the terminal block 123 and the power supply terminal 114 is provided with a tongue that can be inserted into the socket. The power supply terminal 114 is provided with a socket and is connected to the side of the terminal holder 115 facing the top 1111. The terminal block 123 can be inserted into the power supply terminal 114 in the direction from the bottom 1112 to the top 1111, and the terminal block 123 can be disconnected from the power supply terminal 114 in the direction from the top 1111 to the bottom 1112. With this configuration, when the terminal block 123 is pulled out of the power supply terminal 114 from below, external impurities or water droplets can be prevented from falling into the socket of the power supply terminal 114.
[0062] See Figure 4 In some embodiments, to ensure the reliability of the connection between the terminal block 123 and the power supply terminal 114, one of the terminal block 123 and the power supply terminal 114 is provided with a limiting structure 15, and the other of the terminal block 123 and the power supply terminal 114 is provided with an anti-disengagement buckle 16. When the terminal block 123 and the power supply terminal 114 are in the plugged-in state, the anti-disengagement buckle 16 is connected to the limiting structure 15.
[0063] With this configuration, after the power supply terminal 114 and the wiring terminal 123 are plugged in, the anti-dislodgement buckle 16 and the limiting structure 15 can further prevent the power supply terminal 114 and the wiring terminal 123 from falling off, thereby ensuring the reliability of the plugging in.
[0064] As an example, the limiting structure 15 includes a protrusion protruding from the power supply terminal 114, and the anti-disengagement spring clip 16 includes a pressing part on the terminal 123 and a spring clip connected to the pressing part. When the terminal 123 is inserted into the power supply terminal 114, applying external force to the pressing part causes the spring clip to open, thereby allowing the terminal 123 to be inserted into the power supply terminal 114. After the terminal 123 is inserted into the power supply terminal 114, releasing the pressing part causes the spring clip to close and press against the protrusion, thereby achieving anti-disengagement limiting of the terminal 123 and the power supply terminal 114.
[0065] See you later Figure 1 In some embodiments, the air duct device 10 further includes a power supply line 17 embedded between the air duct cover plate 111 and the air duct foam 112. One end of the power supply line 17 is connected to the power supply terminal 114, and the other end of the power supply line 17 is used to connect to the main control board 30 of the refrigerator 1. It should be noted that the power supply line 17 can be pre-embedded between the air duct cover plate 111 and the air duct foam 112, and the power supply line 17 does not need to be removed when disassembling the surface light source assembly 12 and the air duct assembly 11.
[0066] See Figure 1 In some embodiments, at least one of the duct foam 112 and the duct cover 111 is provided with a wire embedding groove 18 communicating with the clearance groove 113, and the power supply line 17 is disposed in the wire embedding groove 18. This arrangement serves two purposes: firstly, the wire embedding groove 18 can prevent the duct cover 111 and the duct foam 112 from squeezing and damaging the power supply line 17; secondly, the wire embedding groove 18 can limit the position of the power supply line 17 and prevent the power supply line 17 from moving around, thereby ensuring the reliability of the circuit connection between the terminal block 123 and the power supply terminal 114.
[0067] See Figure 4 In some embodiments, the duct device 10 further includes a wiring harness limiting seat 116, which is located within the clearance groove 113. At least one of the power supply line 17 and the connecting line 122 passes through the wiring harness limiting seat 116. It should be noted that the wiring harness limiting seat 116 is used to limit at least one of the power supply line 17 and the connecting line 122 to prevent wiring from becoming tangled and short-circuited or the wires from shaking, which could lead to the failure of the circuit connection between the two terminals.
[0068] Of course, in other embodiments, the power supply terminal 114 can also be connected to the main control board of the refrigerator or an external power source via wireless transmission, thereby supplying power to the surface light source assembly 12. It is understood that wireless transmission includes WiFi signal transmission, radio frequency or microwave transmission, etc., and this application does not impose any limitations.
[0069] See Figure 5 and Figure 6The air duct device 10 also includes a protective plate 117, which covers the side of the air duct foam 112 facing away from the air duct cover plate 111 and is connected to the air duct cover plate 111. The protective plate 117 is provided with a clearance hole 118 that overlaps with the clearance groove 113.
[0070] It should be noted that the protective plate 117 is used to cooperate with the duct foam 112 to form the air passage 119 and to cover the duct foam 112. At the same time, the protective plate 117 can also be used to fix the duct foam 112 to the duct cover plate 111. As an example, the protective plate 117 can be set as a PE board.
[0071] In addition, in order to avoid the protective plate 117 from interfering with the clearance groove 113, the protective plate 117 is also provided with a clearance hole 118 that overlaps with the clearance groove 113, so that the wiring terminal 123 and the power supply terminal 114 can be detachably connected to the outside of the air duct assembly 11.
[0072] See Figure 7 and Figure 8 In addition to the aforementioned air duct device 10, this application also provides a refrigerator 1 equipped with the aforementioned air duct device 10. As an example, the refrigerator 1 includes a cabinet 20 and the aforementioned air duct device 10. The cabinet 20 is provided with a cooling compartment 21 and an inner liner 22 located in the cooling compartment 21. The air duct assembly 11 is detachably connected to the inner liner 22, and the surface light source assembly 12 is used to illuminate the cooling compartment 21.
[0073] It should be noted that the refrigeration compartment 21 includes various compartments such as a freezer compartment, a refrigerator compartment, and a variable temperature compartment, and this application 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 111 is used to cooperate with the refrigerator 1's refrigeration system to introduce cold air into the refrigerator 1's air duct and blow it from the air duct's outlet to various parts of the refrigeration compartment 21, thereby reducing the temperature inside the refrigeration compartment 21. The surface light source assembly 12 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.
[0074] The power supply terminal 114 of the air duct device 10 can be connected to the main control board 30 of the refrigerator 1 via the power supply line 17, so as to supply power to the surface light source assembly 12 through the main control board 30 of the refrigerator 1.
[0075] See you later Figure 5 The duct cover 111 is also provided with a mounting structure 19 protruding toward the duct foam 112. The mounting structure 19 is used for detachable connection between the duct cover 111 and the inner liner 22 of the refrigerator 1. The mounting structure 19 can be set at the top 1111, the first side 1113, the second side 1114, the bottom 1112, or the middle position of the duct cover 111, etc., and this application does not impose any limitations. The mounting structure 19 includes a snap-fit, a tongue, or a magnetic structure, etc., and this application does not impose any limitations.
[0076] Thus, for the refrigerator 1 provided in this application, when the surface light source assembly 12 inside the refrigerator 1 needs to be replaced, the air duct device 10 can be removed from the inner liner 22 of the refrigerator 1, and then the surface light source assembly 12 can be separated from the air duct assembly 11, and the wiring terminal 123 and the power supply terminal 114 can be separated. In this way, the surface light source assembly 12 can be replaced in the refrigerator 1 without damaging the internal structure of the air duct assembly 11, so that the air duct assembly 11 can still be used after the surface light source assembly 12 is removed, thereby saving maintenance costs and improving the user experience.
[0077] In addition, the surface light source assembly 12 inside the refrigerator 1 can be detachably connected to the air duct assembly 11, which can also increase the nominal volume of the refrigerator 1.

The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings. All modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
