Description

Technical Field

[0001] This utility model relates to the field of refrigerators, specifically to a wiring box assembly and a refrigerator. Background Technology

[0002] The existing design of wiring boxes in refrigerator door panels has many limitations and urgently needs improvement to enhance performance and user experience. Traditional non-embedded refrigerator door wiring boxes are usually hidden in the hinges, which effectively achieves wiring functionality and maintains a clean appearance. However…

[0003] The inventors discovered that existing technologies suffer from at least the following problems: For built-in refrigerators, due to the special design of their built-in hinges, traditional wiring boxes cannot be hidden within the hinges. Therefore, a movable wiring box is typically installed in the upper front beam of the door. However, during repeated opening and closing of the door, the wiring harness will bend due to repeated reciprocating motion. Long-term use may lead to damage or breakage of the wiring harness, thereby affecting the normal function of the refrigerator. In addition, frequent bending of the wiring harness may also increase the resistance when closing the door, making it difficult to close and affecting the user experience. Utility Model Content

[0050] See Figures 1 to 3 This utility model embodiment provides a wiring box assembly 300, including a wiring box 1 and a wire harness box 2. The wiring box 1 includes a receiving cavity 11 for mounting a wire harness S; wherein the wiring box 1 is configured to limit the bending degree of the wire harness S. The wire harness box 2 includes a mounting cavity 21, one end of the wiring box 1 is located in the mounting cavity 21, and the wiring box 1 is configured to be movable relative to the mounting cavity 21. The wiring box 1 is rotatably connected to a refrigerator door 200, and its position within the wire harness box 2 changes with the opening and closing of the door 200. The movement of the wiring box 1 is as follows: Figure 1 As shown in M. The rotation of the door 200 is as follows. Figure 1 As shown in ω. The wire harness box 2 is used for installation in the refrigerator body 100.

[0051] The cable management box 1 can be injection molded from engineering plastics such as ABS, and the overall structure can be a cuboid. The cable management box 1 has a receiving cavity 11 that extends through both ends, and the cross-section of the receiving cavity 11 is rectangular. The wire harness S passes through the receiving cavity 11. The receiving cavity 11 of the cable management box 1 can accommodate multiple sets of wire harnesses S.

[0052] The cable management box 1 is designed to limit the bending degree of the wire harness S. This can be achieved in several ways: for example, the cable management box 1 includes a flexible plastic tube with a certain degree of rigidity. The wire harness S passes through the plastic tube, allowing it to bend but preventing it from bending to 180°, thus preventing it from folding in half. Alternatively, a protective sleeve can be designed on the outer wall of the area where the wire harness S is prone to folding, or a corner with an arc-shaped transition structure can be provided in the cable management box 1 at the location where the wire harness S is prone to folding, to limit the bending radius of the wire harness S to a set value, such as approximately 10mm.

[0053] The wire harness box 2 can be made of die-cast aluminum alloy or injection-molded from engineering plastics such as ABS. The metal material provides electromagnetic shielding, reducing the impact of external interference on the signal. The wire harness box 2 has a mounting cavity 21, one end of which is open to allow the wiring box 1 to change position within the cavity as the refrigerator door 200 is opened and closed. Optionally, an anti-detachment component can be provided at the open end of the mounting cavity 21 to prevent the wiring box 1 from completely detaching from the cavity 21.

[0054] Cable tray 1 can be installed along the length M of the mounting cavity 21 of cable harness 2. Figure 1As indicated by arrow M, the wiring box 1 moves back and forth, and its range of movement depends on the degree to which the refrigerator door 200 is opened and closed. The direction of movement of the wiring box 1 is not a straight line, but has a certain curvature, because the wiring box 1 moves with the opening and closing of the door 200, and the movement of the door 200 during the opening and closing process is rotation. When it is necessary to adjust the length of the wiring harness S or to perform maintenance, simply push the wiring box 1 to change its length exposed in the wiring harness box 2, without disassembling the entire assembly.

[0055] In the above technical solution, the wiring box 1 not only supports and guides the installation of the wire harness S, but also limits the degree of bending of the wire harness S. During the stretching and retraction of the wiring box 1, the angle can be automatically and randomly adjusted repeatedly according to the movement state of the refrigerator door 200, effectively avoiding damage to the wire harness S due to repeated bending. The wiring box 1 effectively limits the degree of folding of the wire harness S, prevents the wire harness S from being folded in half, protects the wire harness S, greatly reduces the breakage rate of the wire harness S, and is compatible with various different models of wire harness S, effectively extending the replacement cycle of the wire harness S and reducing the cost of consumables.

[0056] See Figure 3 In some embodiments, the cable tray 1 includes a tray body 12 and an anti-bend cable tray 13. The tray body 12 includes a first cover 121 and a second cover 122, which are detachably connected. The first cover 121 and the second cover 122 can be assembled into the tray body 12 as a top cover and a bottom cover, or as a left cover and a right cover. The first cover 121 and the second cover 122 form a receiving cavity 11, in which the wire harness S is constrained. The tray body 12 is open at both ends along its length. The anti-bend cable tray 13 is fixedly installed at one end of the first cover 121 and / or the second cover 122 located within the mounting cavity 21.

[0057] The box body 12 can be made of engineering plastics such as ABS. The box body 12 includes a first cover 121 and a second cover 122, which are detachably and fixedly connected by clips and screws. Both ends of the box body 12 are open to facilitate the threading of the wire harness S. The anti-bend box 13 is a chain structure with multiple anti-bend components 131 made of silicone or metal, hinged together. The wire harness S passes through the inside of the chain structure. The anti-bend box 13 is fixed to one end of the second cover 122 located inside the mounting cavity 21. One section of the anti-bend component 131 at one end of the anti-bend box 13 is connected to the end of the box body 12 located inside the wire harness box 2. Figure 2 The B end of the cable breaker can be rotatably or fixedly connected. The other end of the anti-bend box 13 can be placed in the mounting cavity 21 of the cable harness box 2, and does not need to be fixedly connected to the inner wall of the mounting cavity 21. The number of anti-bend components 131 included in the anti-bend box 13 can be increased or decreased as needed.

[0058] The above technical solution features a compact structure for the housing 12, which facilitates the passage of the wire harness S and ensures high efficiency in wire harness S insertion. The open structure at both ends of the housing 12 forms a continuous protective channel with the anti-bend wire box 13, effectively limiting the degree of bending of the wire harness S, reducing or even eliminating the phenomenon of wire harness S being broken, adapting to various wire harnesses S, and having a lower cost and reduced maintenance costs.

[0059] See Figures 5 to 8 In some embodiments, the anti-bending wire box 13 includes multiple anti-bending components 131, with adjacent anti-bending components 131 being rotatably connected; each anti-bending component 131 includes a main body 131a and an anti-detachment part 131b; the main body 131a includes a hinge hole 131c, the anti-detachment part 131b is fixed to the main body 131a or detachably installed on the main body 131a, and a through hole for accommodating the wire harness S is formed between the anti-detachment part 131b and the main body 131a.

[0060] The number of anti-bending components 131 included in the anti-bending box 13 is related to the length of the wire harness S extending out of the receiving cavity 11 of the wire harness box 2. Each anti-bending component 131 is made of silicone or metal. Adjacent anti-bending components 131 are rotatably connected by a hinge structure.

[0061] The anti-bending cable box 13 uses multiple rotatable anti-bending components 131, allowing the angle of the anti-bending components 131 to be adjusted according to the movement of the cable box 1. When the box door 200 is opened, as... Figure 4 As shown, the wiring box 1 is pulled out, and the corresponding wire harness S is also pulled out. At this time, the anti-bend wiring box 13 is basically straightened to prevent the wire harness S inside the wiring box 2 from being damaged due to mechanical tension caused by bending when the box door 200 is opened. When the box door 200 is closed, as... Figure 1 As shown, the cable management box 1 is pushed back into the wire harness box 2. During the retraction process, the anti-bend cable box 13 moves towards the direction in which excess wire harness S is placed into the wire harness box 2 (i.e., Figure 2 The area shown in the diagram at end B is bent to ensure that the wire harness S can return to the empty position of the wire harness box 2 along the bending direction of the anti-bend box 13. This effectively prevents the wire harness S from bending and accumulating at the tail of the movable wire harness box 1 during the process of being pushed back, which would cause difficulty in closing the door and damage to the wire harness.

[0062] The anti-bend box 13 guides the wire harness S to bend flexibly. The maximum rotation angle of each anti-bend component 131 limits the overall minimum bending radius of the anti-bend box 13, preventing the wire harness S from bending at sharp angles. The through hole can stably constrain the wire harness S within the anti-bend box 13, preventing the wire harness S from coming out or being damaged by friction with the outside. The detachable design of the anti-detachment part 131b facilitates the insertion and replacement of the wire harness S. When the diameter of the wire harness S changes, because the through hole formed by the anti-detachment part 131b and the main body 131a is relatively large, the anti-detachment part 131b does not need to be replaced, and various wire harnesses S of different diameters can be used. The anti-bend box 13 has a wide range of applicability.

[0063] The above technical solution employs a multi-section rotatable anti-bending component 131, which significantly improves the bending adaptability of the anti-bending box 13. The multi-section anti-bending component 131 can naturally deform along with the wire harness S; the excessive bending rate of the wire harness S is greatly reduced, and the risk of insulation layer damage is significantly decreased; the detachable anti-detachment part 131b improves the installation efficiency of the wire harness S and is compatible with various wire harnesses S of different diameters. Through the chain-type design of the anti-bending box 13, the angle can be automatically adjusted according to the movement state of the box door 200 during repeated opening and closing, effectively preventing the wire harness S from bending due to repeated reciprocating motion, thereby protecting the wire harness S from damage and extending its service life. At the same time, it solves the problem of difficulty in closing the box door 200 caused by wire harness bending in traditional designs, improving the smoothness and reliability of the box door 200.

[0064] In some other embodiments, the anti-bend wire box 13 further includes a connecting part 132, which is located at one end of the multi-section anti-bend component 131 and is fixedly or detachably connected to one end section of the multi-section anti-bend component 131; the connecting part 132 is fixedly or detachably connected to the wire harness box 2.

[0065] In other embodiments, the multi-section anti-bending component 131 of the anti-bending box 13 has a connecting portion 132 at one end. The connecting portion 132 is made of the same material as each section of the anti-bending component 131, and the connecting portion 132 also has a through hole that allows the wire harness S to pass through. The connecting portion 132 stably connects the anti-bending box 13 to the wire harness box 2, making the anti-bending box 13 a transition channel for the wire harness S to enter the wire harness box 2 from the wiring box 1, preventing the wire harness S from bending freely without restraint at the connection point. The fixed connection method ensures that the anti-bending box 13 is stable in position during long-term use and is suitable for environments with low vibration; the detachable connection facilitates the individual replacement or maintenance of the anti-bending box 13, and does not require disassembling the entire wire harness box 2 when the anti-bending box 13 is damaged.

[0066] The connector 132 makes it easier to install the anti-bend box 13 and the wire harness box 2, and improves the connection strength. The bending stability of the wire harness S at the transition point is improved, and the excessive bending rate is further reduced. The detachable connection design shortens the replacement time of the anti-bend box 13 and significantly improves maintenance efficiency. The diverse connection methods adapt to different usage scenarios, enhancing the versatility and installation flexibility of the anti-bend box 13.

[0067] See also Figure 2 In some embodiments, one end of the mounting cavity 21 is open, and the cable tray 1 is located in the mounting cavity 21 through the open end. See also Figure 2 The A end of the mounting cavity 21 is open, and the wiring box 1 can move freely at the A end as the door is opened and closed.

[0068] The mounting cavity 21 of the wire harness box 2 has an open design at one end. The opening size of the wire harness box 2 is larger than the cross-section of the wiring box 1, facilitating the entry and exit of the wiring box 1 into the mounting cavity 21. A protective strip or a smooth transition is provided at the edge of the opening to prevent the wiring box 1 from scratching the wire harness S or its own structure when entering or exiting. In addition, a removable baffle can be provided at the edge of the opening; when not in use, the baffle can be closed to prevent debris from entering the mounting cavity 21.

[0069] After the cable tray 1 enters the mounting cavity 21 through the opening, they move relative to each other using a sliding structure. When it is necessary to adjust the cable harness S, the cable tray 1 can be pushed directly from the opening to change its position within the mounting cavity 21, making the operation convenient. The opening also facilitates cleaning and maintenance of the cable tray 1 and the interior of the mounting cavity 21.

[0070] See Figure 2 and Figure 3 In some embodiments, the wiring box assembly 300 further includes a proximity switch 3 and a non-contact triggering component 4. The proximity switch 3 is fixedly installed on the inner wall of the mounting cavity 21. The non-contact triggering component 4 is fixedly installed in the wiring box 1 to move with the wiring box 1. The proximity switch 3 and the non-contact triggering component 4 cooperate; the closer the proximity switch 3 and the non-contact triggering component 4 are, the stronger the magnetic force between them; conversely, the stronger the magnetic force, the weaker the magnetic force. Based on the strength of the magnetic force, it can be determined whether the refrigerator door 200 is in an open or closed state. In some embodiments, the non-contact triggering component 4 includes a magnet. In some embodiments, the magnet is made of neodymium iron boron magnet.

[0071] The proximity switch 3 can be an inductive proximity switch, with a detection distance depending on the refrigerator model, such as 3mm to 5mm. The proximity switch 3 is fixedly installed on the inner wall of the mounting cavity 21 of the wiring harness box 2 using bolts or other fasteners. The sensing surface of the proximity switch 3 faces the wiring box 1, and the lead wire of the proximity switch 3 extends through the wiring hole on the side wall of the wiring harness box 2 to the external control system. Alternatively, the proximity switch 3 can also be wirelessly connected to the control components.

[0072] The non-contact triggering component 4 can specifically use a neodymium iron boron magnet. The magnet is fixed to the outer wall of the wiring box 1 near the wire harness box 2 by adhesive. The height of the non-contact triggering component 4 is basically the same as the height of the proximity switch 3. The strong magnetic properties of the neodymium iron boron magnet ensure stable operation in dusty or slightly vibrating environments.

[0073] When the wiring box 1 moves along the mounting cavity 21, the magnet moves synchronously with the wiring box 1. When the wiring box 1 is pulled outward until the distance between the magnet and the proximity switch 3 is sufficiently large, the magnetic force between the magnet and the proximity switch 3 decreases. When the magnetic force is at its minimum, it indicates that the refrigerator door 200 is in the open state. When the wiring box 1 is pushed inward until the distance between the magnet and the proximity switch 3 is sufficiently small, the magnetic force between the magnet and the proximity switch 3 increases. When the magnetic force is at its maximum, it indicates that the refrigerator door 200 is in the closed state.

[0074] The above technical solution can monitor the movement position of the wiring box 1 in real time. When the wiring box 1 is pulled out to the preset position, a signal is triggered by the proximity switch 3 to indicate that the door 200 has been opened. The proximity switch 3 is directly integrated into the wiring harness box 2, ensuring that both ends of the proximity switch 3 are unobstructed during the opening and closing of the door 200, significantly improving the recognition accuracy and stability of the proximity switch 3. By integrating the wiring harness box 2 with the proximity switch 3, the space on the front beam of the refrigerator door is further freed up, the door structure is optimized, and the overall design is highly integrated and aesthetically pleasing, providing greater possibilities for the internal layout and functional optimization of the refrigerator.

[0075] This utility model embodiment also provides a refrigerator, including a cabinet 100, a door 200, and a wiring box assembly 300 provided by any technical solution of this utility model. The door 200 is rotatably mounted on the cabinet 100. The wiring box assembly 300 provided by any technical solution of this utility model has a wiring box 1 mounted on the door 200 and moving relative to the wiring harness box 2 as the door 200 rotates; the wiring harness box 2 is fixedly mounted on the cabinet 100.

[0076] The enclosure 100 is made of high-strength cold-rolled steel plate and is treated with phosphating, electrophoresis and powder coating to form a uniform anti-rust coating on the surface. The overall structure is rectangular.

[0077] The cabinet door 200 includes a top cover plate 201, a hinge cover plate 202, a door end cover 203, and an embedded part 204, which are spliced ​​together to form a space for installing the hinge 400. The top cover plate 201 is roughly flat and is used to hide the internal structure and improve aesthetics. The hinge cover plate 202 is a multi-plate splicing structure, and the length of the hinge cover plate 202 is shorter than that of the top cover plate 201. The total length of the hinge cover plate 202 and the embedded part 204 is basically the same as the length of the top cover plate 201. The door end cover 203 is also a multi-plate splicing structure. The embedded part 204 is roughly L-shaped. The cabinet door 200 is installed and fixed to the cabinet body 100 by the hinge 400 through the embedded part 204, and the hinge cover plate 202 is provided on the top of the hinge 400. The door end cover 203 is used to hide the hinge 400, hinge cover plate 202 and other structures. Inside the door end cover 203, the hinge 400 is fixed to the door end cover 203 by the embedded part 204, and the hinge cover plate 202 is fixed to the hinge 400. One end of the wiring box 1 is connected to the hinge cover plate 202.

[0078] A hinge cover plate 202 is provided on the upper part of the hinge 400, and a wire harness box 2 is provided inside the hinge cover plate 202. The wire harness box 2 is used to connect and hide the movable wiring box 1. The top of the housing 100 has a wire harness box 2 pre-embedded to place the wiring box 1 and excess wire harnesses S.

[0079] The aforementioned technical solution integrates the proximity switch 3 onto the wiring harness box 2, ensuring that both ends of the proximity switch 3 are unobstructed during the opening and closing of the door 200, significantly improving the recognition accuracy and stability of the proximity switch 3. Even with the extensive use of metal components in the door 200 to enhance its texture, there is no interference with the signal of the proximity switch 3, thus guaranteeing the sensitivity and reliability of the door 200's opening and closing. Furthermore, by integrating the wiring harness box 2 with the proximity switch 3, space is freed up on the front beam of the door, optimizing the door 200 structure and improving the overall compactness and aesthetics. This not only provides greater possibilities for optimizing the refrigerator's internal layout and functions but also reduces the structural limitations caused by occupying space on the front beam in traditional designs, further optimizing the refrigerator's structure and enhancing the user experience.

[0080] See Figure 2 In some embodiments, the refrigerator also includes a hinge 400, which is installed between the cabinet 100 and the door 200 to enable a rotatable connection between the door 200 and the cabinet 100.

[0081] The refrigerator compartment has one or two doors 200. Taking two doors as an example, each door 200 is connected to the body 100 through two hinges 400, which enables the door 200 to be rotatably installed to meet the user's needs for taking out and putting in items.

[0082] The hinge 400 can specifically be an embedded hinge 400, roughly rectangular in shape. Each door 200 can be equipped with two hinges 400, installed above and below the door 200 respectively. The embedded hinge 400 is hidden within the connection gap between the cabinet 100 and the door 200, unlike traditional exposed hinges 400 which disrupt the overall aesthetics of the refrigerator. The embedded hinge 400 has more precise requirements for installation space and is better suited for built-in installation environments. Due to its compact structure, it reduces the space occupied by the hinge 400 itself, allowing the refrigerator to be more tightly embedded in the cabinet, reducing gaps between it and the cabinet, improving space utilization, avoiding hard-to-clean corners, and making the refrigerator and cabinetry look more harmonious. The embedded hinge 400 is in a relatively enclosed environment, reducing the probability of external impacts and friction, and effectively preventing dust and moisture from entering the interior of the hinge 400. This helps maintain the hinge 400 in good working condition, reduces the risk of wear and failure due to impurities, and extends its service life, making it especially suitable for environments with high levels of oil fumes and moisture, such as kitchens. The recessed hinge 400 can be made of high-strength alloy materials and undergoes precision machining and processing to stably support the weight of the door 200. Even with frequent opening and closing, it ensures smooth rotation of the door 200, preventing loosening or sagging, ensuring a tight seal between the door 200 and the cabinet 100, reducing cold air leakage, and guaranteeing the refrigerator's cooling efficiency.

[0083] Furthermore, since the embedded hinge 400 is embedded inside the housing 100 and the door 200, precise alignment is required during installation to ensure proper rotation and sealing of the door 200. Once installed, routine maintenance is minimal, and some embedded hinges 400 are designed with an adjustable structure, allowing for fine-tuning of the door 200's position within a certain range to ensure consistently good sealing. In addition, the embedded hinge 400 is equipped with high-precision bearings and damping components, along with specialized lubricating grease, making the door 200 rotate more smoothly, effectively reducing noise and enhancing the user experience.

[0084] See also Figure 2 In some embodiments, the door 200 and the wiring harness box 2 are located on both sides of the hinge 400.

[0085] One end of the wiring box 1 is rotatably connected to the door 200, specifically by hinge; the other end of the wiring box 1 is located in the mounting cavity 21 of the wire harness box 2. There is a gap between the hinge 400 and the wiring box 1, but the two are relatively close. During the opening and closing of the door 200, the wiring box 1 and the hinge 400 do not contact or interfere with each other.

[0086] When the door 200 rotates around the hinge 400, the rotation angle is within the set range. Since the door 200 and the wire harness box 2 are located on opposite sides of the hinge 400, the wiring box 1 does not contact the hinge 400 along the movement trajectory of the door 200, thus avoiding the cross-entanglement of the wire harness S at the hinge 400.

[0087] When the door 200 is closed, it fits snugly against the front of the cabinet 100, forming a sealed space to ensure the insulation effect of the refrigerator compartment. The edge of the door 200 is equipped with a magnetic sealing strip made of nitrile rubber, which has good elasticity and sealing performance, and makes close contact with the side of the cabinet 100 to prevent cold air leakage.

[0088] The wire harness box 2 is located inside the hinge 400 and fixed to the inner wall of the housing 100. It and the door 200 are located on opposite sides of the hinge 400, respectively. This layout makes the routing of the wire harness S in the wiring box assembly 300 more reasonable. When the door 200 rotates, the wiring box 1 moves with the door 200 next to the hinge 400, while the wire harness box 2 remains fixed inside the hinge 400, avoiding the tangling and compression of the wire harness S at the hinge 400.

[0089] Furthermore, the design of the cabinet door 200 and the wire harness box 2 located on both sides of the hinge 400 facilitates the installation and maintenance of the wiring box assembly 300. When it is necessary to inspect the wire harness S, simply open the cabinet door 200 to easily access the wiring box 1 and the wire harness box 2 without disassembling the hinge 400 or other components, greatly improving maintenance efficiency.

[0090] In use, a non-contact trigger component 4 is installed on one side of the end of the wiring box 1, and a proximity switch 3 is installed on the inner wall of the wiring harness box 2 near the non-contact trigger component 4. When the door 200 is closed, the wiring box 1 returns to the wiring harness box 2, and moves the non-contact trigger component 4 to a position directly facing the proximity switch 3, which then detects the closed state. When the door 200 is opened, the wiring harness box 2 pulls the wiring box 1 outward, and the non-contact trigger component 4 moves away from the proximity switch 3, which then detects the door is open. This technical solution effectively frees up the space on the front beam of the hinge cover in traditional refrigerators where proximity switches are placed. Furthermore, there is no obstruction between the non-contact trigger component 4 and the proximity switch 3, effectively improving the accuracy and stability of the proximity switch 3 in recognizing the door's state.
