Description

Technical Field

[0001] This invention relates to the field of refrigeration, and more particularly to a refrigerator with a winding structure. Background Technology

[0002] With the development of intelligent and multifunctional refrigerators, refrigerator doors are usually equipped with functional modules, such as ice water modules and touch control modules. These functional modules typically need to be connected to the various functional modules inside the refrigerator via wiring harnesses extending from inside the refrigerator. For example, cables extending from inside the refrigerator provide electrical and communication connections between the functional modules on the door and the control module inside the refrigerator; or, water pipes extending from inside the refrigerator supply water to the ice water module on the door.

[0003] In existing refrigerators, wiring is typically routed through the upper hinge of the door. This means the hinge shaft of the upper hinge has a through hole running vertically through it. Wiring extending from the refrigerator body through this through hole reaches the door to connect with various functional modules on the door. However, the number of wires that can pass through is limited by the size of the hinge shaft.

[0004] Chinese Patent Application No. CN110398121A discloses a wiring device for a refrigerator door, including a wiring device connected between the refrigerator body and the door to guide and connect the wiring harness, thus achieving the purpose of transitioning the wiring harness from the refrigerator body to the door. However, during the opening and closing of the door, as the distance between the door and the refrigerator body changes, the wiring harness will generate excess wire, causing the wiring harness to accumulate, which can easily lead to bending and damage of the wiring harness or poor contact, affecting the service life of the refrigerator.

[0005] In view of this, it is necessary to provide a new refrigerator with a winding structure to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide a refrigerator with a wire winding structure that can consume excess wire generated during the opening and closing of the door.

[0007] To achieve the above-mentioned objectives, the present invention adopts the following technical solution: a refrigerator with a wire take-up structure, comprising a cabinet, a door rotatably connected to the cabinet, a wire harness extending from the cabinet and into the door, and a wire take-up structure, wherein the wire harness extends into the door via the wire take-up structure, and the wire take-up structure is used to accommodate the excess wire harness generated during the opening and closing of the door.

[0008] As a further improvement of the present invention, the wire take-up structure includes an elastic member disposed on the wire path of the wire harness. The free end of the elastic member is provided with a through hole for the wire harness to pass through. The excess wire harness generated during the opening and closing of the door is collected at the location of the elastic member under the pull of the elastic member.

[0009] As a further improvement of the present invention, the elastic element includes a columnar spring protruding toward the wire harness, a fixing frame fixed to one end of the columnar spring toward the wire harness, the through hole being provided on the fixing frame, and the end where the fixing frame is located being the free end.

[0010] As a further improvement of the present invention, the take-up structure further includes a mounting cavity for mounting the elastic member, the opening of the mounting cavity facing the routing path of the wire harness, and the elastic member being located inside the mounting cavity when the elastic member is in its natural state.

[0011] As a further improvement of the present invention, a guide structure is provided between the elastic member and the mounting cavity, the guide structure being used to guide the deformation direction of the elastic member.

[0012] As a further improvement of the present invention, the guide structure includes a guide post disposed at the free end of the elastic member and a guide groove communicating with the mounting cavity, wherein the guide post is confined within the guide groove.

[0013] As a further improvement of the present invention, the wire take-up structure is located at the top of the box or the top of the door.

[0014] As a further improvement of the present invention, the refrigerator also includes a wiring module for guiding the wire harness to the door body, and the wire take-up structure is disposed on the wiring module.

[0015] As a further improvement of the present invention, the wiring module includes a fixing member fixed to the housing and protruding toward the door, and a wiring box rotatably connected to the fixing member, wherein the wire harness extends to the door through the fixing member and the wiring box.

[0016] As a further improvement of the present invention, the take-up structure is disposed on the fixing member.

[0017] As a further improved technical solution of the present invention, the refrigerator also includes a wiring box rotatably connected to the cabinet or the door. The wiring box has a rotating shaft rotatably connected to the cabinet or the door and a receiving cavity located on the periphery of the rotating shaft. The rotating shaft and the receiving cavity form the wiring structure. The wire bundle is wound on the rotating shaft and extends to the door.

[0018] The beneficial effects of the present invention are: the refrigerator with a winding structure in the present invention can accommodate the excess wire generated during the opening and closing of the door, which can reduce the bending of the wire, increase the service life of the wire, and enhance the user experience.

[0034] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings. Please refer to the accompanying drawings for further details. Figures 1-15 The figures shown represent preferred embodiments of the present invention. However, it should be noted that these embodiments are not intended to limit the present invention. Equivalent modifications or substitutions in function, method, or structure made by those skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0035] It should be noted that, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, a connection can be a direct connection or an indirect connection through an intermediate medium, a fixed connection or a movable connection or a detachable connection or an integral connection. Among these, a "movable connection" can be a pivotal connection or a relatively movable connection. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0036] Please refer to Figures 1-3 As shown, the present invention provides a refrigerator 100, including a cabinet 1, a hinge plate 2 fixed to the cabinet 1, a door 3 rotatably connected to the hinge plate 2, and a wiring harness 4 extending from the cabinet 1 to the door 3. The wiring harness 4 is connected to a functional module on the door 3 to supply power to the functional module on the door 3. Of course, this is not a limitation; the wiring harness 4 can also be an anti-condensation pipe or a water pipe supplying water to the ice water module on the door 3.

[0037] Specifically, the wiring harness 4 has an outlet end extending from the housing 1 and a docking end extending to the door 3 and connecting with various functional modules on the door 3. The housing 1 has an outlet portion for fixing the outlet end, and the door 3 has a docking portion for fixing the docking end. It is understood that the distance between the outlet portion and the docking portion will change during the opening and closing of the door 3, and the length of the wiring harness 4 between the outlet end and the docking end is not less than the maximum distance between the outlet portion and the docking portion during the opening and closing of the door 3. When the distance between the outlet portion and the docking portion decreases during the opening and closing of the door 3, a wiring harness slack will be generated.

[0038] Furthermore, the refrigerator 100 also includes a take-up structure 5, through which the wire harness 4 led out from the lead-out part extends to the docking part. The take-up structure 5 is used to accommodate the excess wire harness generated during the opening and closing of the door body 3, so as to reduce the bending of the wire harness 4, increase the service life of the wire harness 4, and enhance the user experience.

[0039] Please refer to Figures 3-4 As shown, in the first embodiment of the present invention, the take-up structure 5 is a first take-up structure. This structure includes an elastic member 51 disposed on the routing path of the wire harness 4. The free end of the elastic member 51 has a through hole 511 for the wire harness 4 to pass through. During the opening and closing of the door body 3, any excess wire harness generated is collected at the location of the elastic member 51 under its pull. Under the elastic restoring force of the elastic member 51, the wire harness 4 remains taut, reducing bending, increasing its service life, and enhancing the user experience.

[0040] Specifically, when the distance between the lead-out part and the docking part is at its maximum, the elastic element 51 is in a stretched state. During the opening and closing of the door body 3, when the distance between the lead-out part and the docking part decreases and wire harness slack is generated, the elastic restoring force of the elastic element 51 pulls the wire harness 4 away from the wiring path, thereby indirectly lengthening the wiring path. As a result, the wire harness 4 is always kept in a taut state, which can reduce the bending of the wire harness 4, increase the service life of the wire harness 4, and enhance the user experience.

[0041] Furthermore, the take-up structure 5 also includes a mounting cavity 52 for mounting the elastic member 51. The opening of the mounting cavity 52 faces the routing path of the wire harness 4. When the elastic member 51 is in its natural state, it is located within the mounting cavity 52, that is, the free end of the elastic member 51 is located within the mounting cavity 52. ​​Thus, during the opening and closing of the door body 3, when the distance between the lead-out portion and the docking portion decreases and wire harness slack is generated, the elastic member 51, in a stretched state, pulls the wire harness 4 and accommodates the wire harness slack within the mounting cavity 52.

[0042] Furthermore, a guide structure 53 is provided between the elastic member 51 and the mounting cavity 52. ​​The guide structure 53 is used to guide the deformation direction of the elastic member 51 and enhance the stability of the elastic member 51's extension and contraction.

[0043] Specifically, the guide structure 53 includes a guide post 531 disposed at the free end of the elastic member 51 and a guide groove 532 communicating with the mounting cavity 52. ​​The guide post 531 is confined within the guide groove 532. During the extension and retraction of the elastic member 51, the guide post 531 moves along the guide groove 532 to enhance the stability of the extension and retraction of the elastic member 51.

[0044] In one specific embodiment, the elastic element 51 includes a columnar spring 512 protruding toward the wire harness 4 and a fixing bracket 513 fixed to one end of the columnar spring 512 toward the wire harness 4. A through hole 511 is provided on the fixing bracket 513, and the end of the fixing bracket 513 is the free end. The end of the columnar spring 512 away from the fixing bracket 513 is fixed within the mounting cavity 52, enhancing the stability of the positioning between the elastic element 51 and the wire harness 4. However, this is not a limitation.

[0045] Specifically, the guide post 531 is disposed on the fixing frame 513, simplifying the structure of the elastic element 51. Of course, this is not a limitation.

[0046] In this embodiment, the cable winding structure 5 is located at the top of the door body 3. However, this is not a limitation; in other embodiments, the cable winding structure 5 may also be located at the top of the housing 1.

[0047] Specifically, the door body 3 includes a door panel and an upper trim strip 31 located at the top of the door panel. A mounting cavity 52 is recessed downwards from the top of the upper trim strip 31, and an elastic element 51 is fixed within the mounting cavity 52. ​​A wire harness 4, extending from the housing 1, passes through a through-hole 511 in the elastic element 51 and extends to a mating portion on the door body 3. During the opening and closing of the door body 3, any excess wire harness is collected within the mounting cavity 52 under the pull of the elastic element 51. Under the elastic restoring force of the elastic element 51, the wire harness 4 remains taut, reducing bending, increasing its lifespan, and enhancing the user experience.

[0048] Furthermore, the upper trim strip 31 is recessed downward to form a receiving cavity 33, and the wire take-up structure 5 is disposed on the receiving cavity 33. The wire harness 4 passing through the wire take-up structure 5 is also received in the receiving cavity 33, which can reduce the impact of the wire harness 4 on the appearance of the refrigerator 100.

[0049] Furthermore, the refrigerator 100 also includes a cover 8 that cooperates with the receiving cavity 33. The cover 8 is fixed to the door 3 by fasteners such as screws and covers the receiving cavity 33, thereby improving the overall appearance of the refrigerator 100.

[0050] Furthermore, the refrigerator 100 also includes a wiring module 6 for guiding the wiring harness 4 to the door 3, through which the wiring harness 4 extends to the door 3. By additionally providing the wiring module 6, the limitations of hinge wiring in the prior art are reduced, the extension trajectory of the wiring harness can be flexibly adjusted, and wire jamming is avoided.

[0051] In this embodiment, the take-up structure 5 is disposed on the door body 3 and located between the outlet end of the wiring module 6 and the docking part on the door body. The wire harness 4 led out from the wiring module 6 extends to the docking part after passing through the take-up structure 5. During the opening and closing of the door body 3, the excess wire harness is contained in the mounting cavity 52 under the action of the elastic member 51, keeping the wire harness 4 in a taut state at all times. This reduces bending of the wire harness 4, increases its service life, and enhances the user experience.

[0052] Please refer to Figures 5-14 As shown, this is the second embodiment of the present invention. The difference between the second embodiment and the first embodiment is that the take-up structure 5 is disposed on the wiring module 6.

[0053] In this embodiment, the take-up structure 5 is the same as the take-up structure 5 in the first embodiment, and will not be described again here.

[0054] Specifically, please refer to Figure 6 As shown, the wiring module 6 includes a wiring box 61 for guiding at least a portion of the wire harness 4 to the door body 3. The wiring box 61 has a movable end 611 and a pivot end 612 disposed opposite to each other. One of the movable end 611 and the pivot end 612 cooperates with the housing 1, and the other cooperates with the door body 3. As the door body 3 is opened and closed, the movable end 611 can move, and the pivot end 612 can rotate. The wiring box 61 does not affect the opening and closing of the door body 3. At the same time, it allows the wire harness located in the wiring box 61 to move freely with the opening and closing of the door body 3. The wiring box 61 can guide the wire harness 4 inside, so that the wire harness 4 moves regularly with the wiring box 61 during the opening and closing of the door, avoiding the wire harness 4 from getting tangled or bent and worn, and improving the service life of the wire harness 4.

[0055] In one specific embodiment, the pivot end 612 is rotatably connected to the housing 1, and the movable end 611 is movably connected to the door 3. Of course, this is not a limitation; in other embodiments, the pivot end 612 may also be rotatably connected to the door 3, in which case the movable end 611 is movably connected to the housing 1.

[0056] Further, please refer to Figures 10-14As shown, the wiring module 6 further includes a fixing member 62 fixed to the housing 1 and protruding towards the door 3. The fixing member 62 is arranged side by side with the hinge plate 2. The pivot end 612 is rotatably connected to the front end of the fixing member 62. At least a portion of the wires extend sequentially through the fixing member 62 and the wiring box 61 to the door 3, realizing an indirect pivotal connection between the wiring box 61 and the housing 1. Of course, this is not a limitation. In other embodiments, the pivot end 612 of the wiring box 61 can also be directly rotatably connected to the housing 1, and the movable end 611 can be movably connected to the door 3. That is, the pivot end 612 is located in the upper region of the housing 1, and the pivot end 612 is rotatably connected to the housing 1.

[0057] Furthermore, the wiring box 61 is housed within the receiving cavity 33. During the opening and closing of the door 3, the wiring box 61 remains within the receiving cavity 33. That is, the wiring box 61 is not exposed during the opening and closing of the door 3, thereby achieving the effect of concealing the wiring box 61 and preventing it from affecting the appearance of the refrigerator 100 and its normal use.

[0058] Meanwhile, the shielding cover 8 can restrict the upward movement of the wiring box 61, thereby improving the stability of the movement of the wiring box 61.

[0059] In this embodiment, the wire take-up structure 5 is disposed on the fixing member 62. Of course, this is not a limitation, and the wire take-up structure 5 can also be disposed on the cable tray 61.

[0060] Specifically, the fixing member 62 has an outwardly protruding protrusion 621, and the wire take-up structure 5 is provided at the protrusion 621.

[0061] Specifically, the fixing member 62 has a wiring groove 622 for the wire harness to pass through, and the mounting cavity 52 is recessed from the side of the protrusion 621 toward the wiring groove 622 toward the direction away from the wiring groove 622, so that the wiring groove 622 is connected to the mounting cavity 52.

[0062] In one specific embodiment, the protrusion 621 is located on the side of the wiring groove 622 away from the hinge plate 2, that is, the mounting cavity 52 is located on the side of the wiring groove 622 away from the hinge plate 2. Of course, this is not a limitation.

[0063] Specifically, the fixing member 62 is a plastic or nylon part, which can directly form the cable routing groove 622 and the protrusion 621 during the molding process, and form the mounting cavity 52. ​​This facilitates the installation of the cable take-up structure 5 and reduces costs. At the same time, the fixing member 62 has good toughness and wear resistance, which can reduce noise when rotating relative to the cable routing box 61. Of course, this is not a limitation. In other embodiments, the fixing member 62 and the hinge plate 2 can also be integrally set, that is, the fixing member 62 is part of the hinge plate 2, and the cable routing box 61 is rotatably connected to the hinge plate 2 at a position corresponding to the upper area of ​​the door body 3.

[0064] Further, please refer to Figures 10-11 As shown, a limiting structure 63 is provided between the fixing member 62 and the hinge plate 2. It can be seen that the hinge plate 2 is generally made of a metal with high rigidity, has good load-bearing capacity, and is not easily deformed. By limiting the fixing member 62 on the hinge plate 2 through the limiting structure 63, the fixing member 62 can be restricted from shaking in the vertical direction through the hinge plate 2. Thus, it can prevent the wiring box 61 from being misaligned in the vertical direction and enhance the stability of the fit between the wiring box 61 and the door body 3.

[0065] In one specific embodiment, the limiting structure 63 includes at least one upper abutment piece 631 protruding from the fixing member 62 toward the hinge plate 2, and a lower abutment wall 632 protruding from the lower side of the fixing member 62 toward the hinge plate 2. The upper abutment piece 631 is located above the lower abutment wall 632 and is spaced apart from the lower abutment wall 632. The lower abutment wall 632, the upper abutment piece 631, and the side of the fixing member 62 facing the hinge plate 2 together form an abutment groove. After the hinge plate 2 is engaged in the abutment groove, the upper surface of the hinge plate 2 abuts against the upper abutment piece 631, and the lower surface of the hinge plate 2 abuts against the lower abutment wall 632, thereby restricting the fixing member 62 from swaying in the vertical direction. Of course, this is not a limitation; in other embodiments, the limiting structure 63 may also be provided on the side of the hinge plate 2 facing the fixing member 62.

[0066] Specifically, the limiting structure 63 includes at least two upper abutment pieces 631, which are arranged at intervals along the front-back direction to respectively limit the fixing member 62, thereby improving the stability of the wiring box 61. Of course, this is not a limitation.

[0067] Furthermore, the refrigerator 100 also includes a hinge box 7 fixed to the cabinet 1, and the fastener 62 is fixed to the hinge box 7. The fixed connection between the fastener 62 and the cabinet 1 is achieved by fixing the hinge box 7 to the cabinet 1, which can reduce the connection parts on the cabinet 1 and simplify the assembly of the refrigerator 100.

[0068] Furthermore, after the fastener 62 is fixed to the hinge box 7, the hinge box 7 completely covers the fastener 62 and the hinge plate 2, enhancing the appearance of the refrigerator 100.

[0069] Specifically, the hinge box 7 includes a middle hinge box 71 and a first hinge box 72 located at the end of the middle hinge box 71. The fixing member 62 is fixed to the middle hinge box 71. After the fixing member 62 and the hinge box 7 are assembled, the first hinge box 72 covers the hinge plate 2 and part of the fixing member 62, and the middle hinge box 71 covers other parts of the fixing member 62.

[0070] Furthermore, the hinge box 71 has a receiving portion 711 that protrudes toward the door body 3 and is used to receive the fastener 62, the shape of the receiving portion 711 being adapted to the shape of the fastener 62.

[0071] Specifically, the receiving portion 711 includes an upper wall 7111 that covers the upper surface of the fixing member 62, a support wall 7112 that supports the lower surface of the fixing member 62, and a connecting wall 7113 that connects the upper wall 7111 and the support wall 7112 on one side. After the fixing member 62 is fixed to the hinge box 7, the part of the fixing member 62 that protrudes toward the door body 3 is received in the receiving portion 711, and the fixing member 62 is supported on the support wall 7112.

[0072] In one specific embodiment, the support wall 7112 protrudes toward the hinge plate 2 to form the aforementioned lower abutment wall 632, simplifying the structure of the fastener 62. However, this is not a limitation.

[0073] Furthermore, one of the hinge plate 2 and the door body 3 is provided with a hinge shaft 21, and the other is provided with a bushing (unlabeled) that cooperates with the hinge shaft 21, so as to rotatably connect the door body 3 to the hinge plate 2.

[0074] Furthermore, the hinge shaft 21 has a through hole extending through it along its axial direction. The through hole is used to guide at least a portion of the wiring harness 4 of the housing 1 to the door 3. That is, in this invention, part of the wiring harness 4 leading out from the housing 1 extends to the door 3 via the hinge plate 2, and another part extends to the door 3 via the wiring module 6. This reduces the limitations of existing hinge wiring and allows for flexible adjustment of the extension trajectory of each wiring harness 4, avoiding wire jamming.

[0075] Furthermore, the fastener 62 is provided with at least one buckle 623 for fixing the wiring on the side facing the hinge plate 2. The wire harness 4 that needs to pass through the through hole is first fixed and arranged by the buckle 623 before passing through the through hole, so as to avoid the wire harness 4 leading out from the housing 1 from becoming messy.

[0076] In one specific embodiment, the buckle 623 is an L-shaped buckle 623. Of course, it is not limited to this.

[0077] Furthermore, one of the movable end 611 and the door body 3 is provided with a limiting post 613, and the other is provided with a limiting groove 32 that cooperates with the limiting post 613. That is, the movable connection between the movable end 611 and the door body 3 is realized through the mutually cooperating limiting post 613 and limiting groove 32, and the structure is relatively simple.

[0078] During the opening and closing of the door 3, the limiting groove 32 guides the movement of the limiting post 613. As the limiting post 613 moves along the limiting groove 32, it drives the wiring box 61 and the wiring inside the wiring box 61 to move regularly, avoiding tangling, bending, or wear of the wiring harness and improving its service life. At the same time, during the opening and closing of the door 3, it also avoids collisions and friction between the wiring box 61 and other parts of the door 3, reducing noise and improving service life.

[0079] In one specific embodiment, the limiting post 613 is disposed on the movable end 611, and the limiting groove 32 is correspondingly disposed on the door body 3. It is understood that the door body 3 has a large and flexible space for installation, which simplifies the placement of the limiting groove 32 and allows for miniaturization of the wiring box 61. Of course, this is not a limitation; it is understood that in other embodiments, the limiting post 613 can also be disposed on the door body 3, and the limiting groove 32 can be correspondingly disposed on the wiring box 61.

[0080] Furthermore, in the embodiment where the limiting groove 32 is provided on the door body 3, the limiting groove 32 extends obliquely from front to back and toward the hinge shaft 21, so that the opening and closing of the door body 3 is not restricted by the wiring box 61, and the door body 3 can be opened and closed freely.

[0081] Of course, the limiting groove 32 is not limited to the above-mentioned extension direction, and can be adaptively adjusted according to the movement trajectory of the limiting post 613 during the opening and closing of the door body 3.

[0082] Specifically, the limiting groove 32 is provided on the upper trim strip 31, and the opening of the limiting groove 32 is upward-opening. The limiting post 613 protrudes downward from the movable end 611, simplifying the arrangement of the limiting groove 32 and the limiting post 613. Of course, this is not a limitation. It can be understood that the opening direction of the limiting groove 32 and the protrusion direction of the limiting post 613 only need to correspond, and the limiting post 613 can also be set in a bent shape, as long as the end of the limiting post 613 can protrude from the opening into the limiting groove 32.

[0083] Furthermore, the pivot end 612 has a pivot shaft 6121, through which a pivotal connection is realized with the fixing member 62.

[0084] Please refer to Figure 15 As shown, in the third embodiment of the present invention, the pivot end 612 further has an annular receiving cavity 6122 located on the periphery of the rotating shaft 6121. The rotating shaft 6121 and the receiving cavity 6122 form the wire take-up structure 5' in this embodiment. The wire take-up structure 5' is a second wire take-up structure, that is, the wire take-up structure 5' is provided on the wiring box 61, and the wire bundle 4 extends to the door body 3 after being wound around the rotating shaft 6121.

[0085] When the distance between the opening / closing door body 3 and the lead-out and docking parts is at its maximum, the wire harness 4 wound around the rotating shaft 6121 is either layered or spirally wound around the rotating shaft 6121. The excess wire harness generated during the opening / closing process diffuses around the rotating shaft 6121 and is contained within the receiving cavity 6122, reducing bending of the wire harness 4, increasing its service life, and enhancing the user experience.

[0086] The third embodiment of the present invention is identical to the second embodiment except for the structure and placement of the above-mentioned take-up structure, and will not be described again here.

[0087] Specifically, please refer to Figure 14 As shown, the wiring box 61 includes a first housing 64 and a second housing 65 that surround a wiring cavity to accommodate a wire harness. One end of the first housing 64 and the second housing 65 are connected by a snap-fit ​​structure 66, and the other end is fixedly connected by a fastener 67.

[0088] Specifically, the engaging structure 66 includes a protrusion 661 on one of the first housing 64 and the second housing 65, and an engaging groove 662 on the other. The engaging groove 662 extends along the length of the wiring box 61, and one end of the engaging groove 662 corresponding to the end of the wiring box 61 has an engaging opening for the protrusion 661 to enter and exit. When assembling the first housing and the second housing 65, the protrusion 661 is inserted into the engaging groove 662 from the engaging opening. Then, after aligning the fastening holes on the other end of the first housing 64 and the second housing 65 that cooperate with the fastener 67, the fastener 67 is screwed in.
