Description

Technical Field

[0001] This application relates to the field of refrigeration, and in particular to a refrigerator. Background Technology

[0002] Feedback from the current refrigerator market indicates that the hinge area frequently produces noise, accompanied by the problem of easily worn-out wiring. In-depth experimental analysis revealed that the root cause of this problem lies in a flawed design of the wiring opening in the refrigerator hinge cover. To facilitate wiring, the hinge cover opening is designed as a circular opening. However, during daily use of the refrigerator door, this design causes the contact point between the hinge cover and the wiring harness to become too sharp. The wiring harness easily gets caught and worn under repeated friction, producing unpleasant noise. More seriously, prolonged friction and wear will gradually thin the wiring harness, reducing its strength and eventually posing a risk of breakage, affecting the normal operation of the refrigerator.

[0034] To provide a better understanding of the purpose, structure, features, and functions of this application, detailed descriptions are provided below with reference to specific embodiments.

[0035] To address the aforementioned problems, this application provides a refrigerator 100, which includes a cabinet 1, a door 2, and a wiring assembly 3. The cabinet 1 has a cavity with an open side for storing food and other items. The door 2 is pivotally connected to the cabinet 1 via a hinge assembly for closing or opening the cavity. The wiring assembly 3 includes a wiring box 31 and a cable 32. The wiring box 31 has an elongated cable outlet 311. One end of the cable 32 is connected to the door 2, and the other end passes through the cable outlet 311 and is connected to the cabinet 1.

[0036] The wiring assembly 3 is configured such that when the door 2 closes the cavity, the cable 32 passes through the outlet 311 and bends into a U-shape, and the length extension direction of the outlet 311 is consistent with the direction of the two sides of the U-shape of the cable 32.

[0037] Cable 32 is an important component of the internal circuit system of refrigerator 100, responsible for transmitting electrical and control signals. One end of cable 32 is securely connected to the corresponding position on the door 2, and the other end passes through the outlet 311 of the wiring box 31 and connects to the internal circuit system of the cabinet 1.

[0038] The elongated cable outlet 311 typically has a relatively long length and a narrow width, forming a relatively long and narrow through-hole. Its length and width can be customized to accommodate cables 32 of different diameters and types; specifically, the elongated shape can be elliptical, rectangular, etc. The elongated cable outlet 311 is commonly used in cable management boxes 31 to guide the connection of cables 32 between the door 2 and the housing 1. When the door 2 is closed, the cable 32 passes through the elongated cable outlet 311 of the cable management box 31 and bends into a U-shape. The long axis of the elongated outlet aligns with the direction of the two sides of the U-shape of the cable 32 to maintain the smoothness and stability of the cable 32.

[0039] This effectively avoids the problems of cable 32 getting snagged and worn due to friction in traditional circular opening designs. Because when cable 32 is bent into a U-shape, its movement trajectory is smoother, and its contact with the outlet 311 is gentler, thereby reducing noise generation and lowering the risk of cable breakage.

[0040] The cable 32 is configured such that when the door 2 pivots relative to the housing 1, the cable 32 passes through the outlet 311 and is connected to a section of the housing 1 and remains stationary.

[0041] In this application, the cable 32 includes a fixed section and a movable section connected to each other. The fixed section is a part of the cable 32 from the elongated cable outlet to the housing 1, and the movable section is a part of the cable 32 from the door 2 to the elongated cable outlet 311. The fixed section is connected to the housing 1 to ensure that the fixed section of the cable 32 is not excessively stretched when the door 2 pivots; one end of the movable section is connected to the door 2 and is slightly stretched as the door 2 pivots. The movable section can move slightly and smoothly within the cable outlet 311 when the door 2 opens and closes.

[0042] The fixed section of cable 32 remains stationary, while the movable section moves with the pivoting of the door 2, effectively reducing friction and wear between cable 32 and outlet 311.

[0043] In one embodiment, the cable outlet 311 is elliptical. The ellipse has both a certain length and a certain width, accommodating the bending and movement of the cable 32 as the door 2 pivots. Compared to a circular cable outlet 311, it provides more space for cable threading, reduces the contact pressure between the cable 32 and the edge of the outlet 311, and lowers friction and wear. The major axis of the ellipse provides sufficient clearance for the movement of the cable 32, while the minor axis limits the position of the cable 32 to a certain extent.

[0044] The cable 32 passes through the outlet 311, and the edge of the outlet 311 along the long axis has clearance space from the cable 32.

[0045] The long axis of the elongated outlet 311 is consistent with or close to the bending direction of the cable 32, that is, consistent with or close to the direction of the two sides of the U-shaped structure of the cable 32. At this time, the cable 32 undergoes a large bending deformation when passing through the outlet 311. The edge along the long axis needs to be designed with sufficient clearance space to accommodate the deformation of the cable 32 when bending.

[0046] The specific dimensions of the clearance space are determined based on the diameter, material, and bending radius of the cable 32. The clearance space can reduce or even avoid the contact pressure between the cable 32 and the edge of the outlet 311, thereby reducing friction and wear, while ensuring that the cable 32 maintains an appropriate bending radius when bending, and preventing the cable 32 from being damaged due to excessive bending.

[0047] The door body 2 includes a door trim 21, and the cable 32 is connected to the door trim 21.

[0048] Door trim 21 is typically located on the edge or at a specific position of the door body 2. In addition to its decorative function, door trim 21 may also serve as a connection point or fastener for cable 32. It may have internal wire channels or clamps for securing and guiding cable 32. One end of cable 32 can be connected to door trim 21 by means of welding, crimping, plugging, or connectors.

[0049] The door trim strip 21 includes a wiring opening, and the cable 32 is connected to the wiring opening through a rubber plug 33, with the rubber plug 33 having an interference fit with the wiring opening.

[0050] The door trim 21 is provided with a cable routing opening for threading and fixing the cable 32. The cable routing opening is usually located on the edge of the door trim 21 or other specific locations. The shape of the cable routing opening can be round, oval or other shapes suitable for the cable 32 to pass through. This application does not impose any specific restrictions.

[0051] The rubber plug 33 is a plug made of elastic material used to fix the cable 32 to the cable routing port. The rubber plug 33 and the cable routing port adopt an interference fit, that is, the diameter of the rubber plug 33 is slightly larger than the diameter of the cable routing port, to ensure that the rubber plug 33 fits tightly inside the cable routing port and will not loosen or fall off due to the movement of the door 2, thus providing a firm fixation for the cable 32.

[0052] When installing the rubber plug 33, the cable 32 needs to be passed through the cable routing port before the rubber plug 33 is pressed firmly into the cable routing port. When disassembling, the rubber plug 33 needs to be pulled out of the cable routing port.

[0053] The cable routing assembly 3 also includes a limiting member 34, which limits a section of the cable 32 from the door 2 to the outlet 311.

[0054] The limiting member 34 is disposed in the middle of the movable section of the cable 32 to limit the movable section of the cable 32, that is, to limit the section of the cable 32 from the door 2 to the outlet 311, so as to ensure that the cable 32 maintains a stable path and position during the movement of the door 2.

[0055] The limiting member 34 includes a main body and a stop portion vertically connected to the main body. The main body is connected to the door trim strip 21, and the stop portion limits the distance between the movable section of the cable 32 and the door body 2. That is, the stop portion ensures that the U-shaped movable section of the cable 32 after bending is always close to the door body 2, preventing the cable 32 from shaking or shifting when the door body 2 is opened and closed; ensuring the relative position between the cable 32 and other parts of the door body 2 is stable, avoiding interference or wear.

[0056] The limiting component 34 and the door trim strip 21 can be integrally formed or separately formed; this application does not impose specific restrictions.

[0057] The hinge assembly includes a hinge cover 4, and the cable tray 31 is snapped into the hinge cover 4 and forms a cable tray cavity with the hinge cover 4. The cable tray cavity guides the cable 32 to the housing 1.

[0058] The hinge assembly connects the door body 2 and the housing 1, allowing them to rotate relative to each other in a pivotal manner. The hinge cover 4, part of the hinge assembly, covers the outside of the hinge, serving both protective and aesthetic purposes. The cable tray 31 is a box for housing and guiding cables 32. The cable tray 31 is connected to the hinge cover 4 via a snap-fit ​​structure on its outer edge, forming a closed or semi-closed space together with the hinge cover 4—the cable tray cavity. The cable tray cavity allows the cables 32 to be arranged in an orderly manner, avoiding clutter and tangling, while also protecting the cables 32 from damage caused by the external environment.

[0059] The cable routing cavity is provided with a cable management structure 312 to limit the cable 32.

[0060] In this application, the cable management structure 312 can be configured according to the diameter, quantity and routing path of the cable 32. For example, the cable management structure 312 can be configured on the side of the cable box 31 near the hinge cover 4, or on the side of the hinge cover 4 near the cable box 31. The cable management structure 312 can also be selected as a slot, clamp, strap or other form of fixing device to adapt to the needs of different cables 32.

[0061] In an optional embodiment, the cable management structure 312 is disposed on the side of the cable box 31 near the hinge cover 4, and the clamping structure is selected to limit and fix the cable 32.

[0062] The clamping structure consists of two opposing hook-shaped structures.

[0063] The hinge assembly also includes a biaxial hinge.

[0064] In other alternative embodiments, the refrigerator 100 to which the technical solution described in this application applies is connected to its door 2 and cabinet 1 by a dual-axis hinge. The dual-axis hinge allows the refrigerator 100 door 2 to rotate in two different directions. During rotation, the door 2 undergoes a more complex motion trajectory, including translation, rotation, and possible torsional deformation, thus providing the door 2 with a larger opening angle and greater flexibility. Therefore, the complex motion characteristics generated by the refrigerator 100 door 2 connected by the dual-axis hinge increase the chance of the cable 32 being subjected to stress and friction.

[0065] This application relates to a refrigerator 100, including a cabinet 1, a door 2, and a wiring assembly 3. The cabinet 1 has a cavity with one side open. The door 2 is pivotally connected to the cabinet 1 via a hinge for closing or opening the cavity. The wiring assembly 3 includes a wiring box 31 and a cable 32. The wiring box 31 has an elongated cable outlet 311. One end of the cable 32 is connected to the door 2, and the other end passes through the cable outlet 311 and is connected to the cabinet 1. The wiring assembly 3 is configured such that when the door 2 closes the cavity, the cable 32 passes through the cable outlet 311 and bends into a U-shape, and the length extension direction of the cable outlet 311 is consistent with the direction of the two sides of the U-shape of the cable 32.
