Description

Technical Field

[0001] This invention relates to the field of household appliances, and more particularly to a refrigerator. Background Technology

[0002] With the development of refrigerators towards intelligence and multi-functionality, refrigerator doors are usually equipped with some functional modules, such as ice water modules and touch control modules. These functional modules usually need to be connected to the control module in the refrigerator body through wiring in order to enable power supply to each functional module on the door.

[0003] In existing refrigerators, wiring is typically routed through the door hinges. The hinge shaft has a through-hole running vertically through the door, and the wiring extending from the refrigerator body passes through this through-hole to the door to connect with various functional modules on the door. However, this technology has the following drawbacks: Limited by the size of the hinge shaft, the through-hole cannot be very large, thus restricting the thickness and number of wiring. This is especially true for refrigerators with door-mounted ice-cooling functions, where thicker water pipes also need to connect to the ice-water modules on the door through the through-hole. In this case, the hinge alone cannot connect all the wiring. Summary of the Invention

[0004] The purpose of this invention is to provide a refrigerator that facilitates the routing of connecting pipelines between the refrigerator body and the door body by providing a movable wiring box with a guide block and rotatably connected to the refrigerator body, and an arc-shaped guide groove formed on the door body that cooperates with the guide block.

[0005] To achieve the above-mentioned objective, one embodiment of the present invention provides a refrigerator, including a cabinet, a door rotatably connected to the cabinet, and a wiring module for guiding the connecting pipes between the cabinet and the door, wherein the wiring module includes:

[0006] A fixed cable box includes a first end, a second end, and a first cable channel passing through the first end and the second end. The first end is fixedly installed in the box body, and the second end extends toward the door body.

[0008] The fourth end is provided with a guide block, and the door body is provided with a guide groove that cooperates with the guide block. The guide block is placed in the guide groove. The connecting pipeline passes through the first wiring channel and the second wiring channel from the box body to the door body. When the door body rotates relative to the box body, the movable wiring box rotates relative to the fixed wiring box, and the guide block slides in the guide groove.

[0009] The guide groove is arc-shaped and includes a starting end near the outer wall of the door and a terminating end near the inner wall of the door. The terminating end is close to the rotation axis of the door relative to the starting end.

[0011] As a further improvement of one embodiment of the present invention, in the refrigerator, when the door is opened to the maximum preset angle, the guide block is located at the end of the guide groove, the guide block slides between the starting end and the ending end, and the width of the guide groove gradually decreases from the starting end to the ending end.

[0012] As a further improvement of one embodiment of the present invention, in the refrigerator, a hinge is provided between the door and the cabinet. One end of the hinge is fixedly disposed on the cabinet, and the other end is provided with a hinge shaft rotatably connected to the door. The rotation axis of the door is the axis of the hinge shaft. The fixed wiring box is disposed at the hinge. The rotation axis of the door is close to the side wall of the hinge and the inner wall of the door. The rotation axis of the movable wiring box is close to the outer wall and is disposed away from the side wall of the hinge relative to the rotation axis of the door. The angle between the surface formed by the rotation axis of the movable wiring box and the rotation axis of the door and the surface of the inner wall is greater than 45 degrees. The guide groove is away from the hinge relative to the rotation axis of the movable wiring box.

[0013] As a further improvement of one embodiment of the present invention, in the refrigerator, the guide groove includes a first guide arc surface and a second guide arc surface spaced apart, the guide block is located between the first guide arc surface and the second guide arc surface, the radius of curvature of the first guide arc surface is smaller than the radius of curvature of the second guide arc surface, the center of curvature of the first guide arc surface is located between the rotation axis of the movable wiring box and the side wall at the hinge of the door, and between the rotation axis of the movable wiring box and the rotation axis of the door, and the center of curvature of the second guide arc surface is located between the center of curvature of the first guide arc surface and the rotation axis of the movable wiring box, and between the rotation axis of the movable wiring box and the outer wall.

[0014] As a further improvement of one embodiment of the present invention, in the refrigerator, the central angles corresponding to the first guide arc surface and the second guide arc surface are both greater than 45 degrees.

[0015] As a further improvement of one embodiment of the present invention, in the refrigerator, the distance between the inner wall and the outer wall is greater than or equal to 90mm, the distance between the rotation axis of the movable wiring box and the outer wall is less than 40mm, the distance between the rotation axis of the movable wiring box and the side wall at the hinge of the door is less than 50mm, and the distance between the starting end and the outer wall is less than 20mm.

[0016] As a further improvement of one embodiment of the present invention, in the refrigerator, the distance between the guide block and the rotation axis of the movable wiring box is between 45mm and 75mm.

[0017] As a further improvement of one embodiment of the present invention, in the refrigerator, the radius of curvature of the first guide arc surface is 15-30mm larger than the distance between the guide block and the rotation axis of the movable wiring box, the radius of curvature of the second guide arc surface is 10-25mm larger than the radius of curvature of the first guide arc surface, and the width of the door is less than or equal to 430mm.

[0018] As a further improvement of one embodiment of the present invention, in the refrigerator, the door end is provided with a first accommodating area and a cover covering the first accommodating area. The hinge shaft, the fixed wiring box, the movable wiring box, and the guide groove are all provided in the first accommodating area. The first accommodating area is provided with a connecting part for connecting the cover. The connecting part is provided on the wall surface of the first accommodating area facing the hinge sidewall of the door, and / or on the wall surface of the first accommodating area near the inner wall.

[0019] Compared with the prior art, the present invention has the advantage of facilitating the routing of connecting pipelines between the box and the door by setting up a movable wiring box with a guide block and rotatably connected to the box, and an arc-shaped guide groove formed on the door that cooperates with the guide block.

[0023] The present invention will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the scope of protection of the present invention.

[0024] Reference Figures 1 to 3 In one embodiment of the present invention, a refrigerator 1 is provided, which may include a cabinet 2, a door 3 rotatably connected to the cabinet 2, and a wiring module for guiding the connecting pipeline 10 between the cabinet 2 and the door 3.

[0025] The cabinet 2 may include a freezer compartment and a refrigerator compartment 4 located above the freezer compartment. A door 3 is used to open and close the refrigerator compartment 4. A water storage box for storing water may be installed inside the refrigerator compartment 4. An ice-water module may be installed inside the door 3. The ice-water module may include an ice maker for making ice cubes and a dispenser 5 for dispensing ice cubes and drinking water to the user upon specific user operation commands.

[0026] The connecting pipeline 10 between the housing 2 and the door 3 may include a water pipe for conveying water from the water storage box to the ice maker and dispenser 5, electrical wires for supplying power to the ice maker and dispenser 5, and electrical wires for controlling the ice maker and dispenser 5.

[0027] The wiring module may include a fixed wiring box 6 and a movable wiring box 7.

[0028] The fixed cable box 6 may include a first end 61, a second end 62, and a first cable channel 63 passing through the first end 61 and the second end 62. The first end 61 may be fixedly installed on the box body 2, and the second end 62 extends toward the door body 3.

[0029] The movable cable box 7 may include a third end 71, a fourth end 72, and a second cable channel 73 passing through the third end 71 and the fourth end 72. The third end 71 is rotatably connected to the second end 62. The axis of rotation of the movable cable box 7 relative to the fixed cable box 6 is parallel to the axis of rotation of the door 3 relative to the housing 2.

[0030] The fourth end 72 may be provided with a guide block 74, and the door body 3 may be provided with a guide groove 9 that cooperates with the guide block 74, and the guide block 74 may be placed in the guide groove 9.

[0031] The connecting pipeline 10 can pass through the first wiring channel 63 and the second wiring channel 73 from the box 2 to the door 3. When the door 3 rotates relative to the box 2, the movable wiring box 7 can rotate relative to the fixed wiring box 6, and the guide block 74 can slide in the guide groove 9.

[0032] The guide groove 9 may be arc-shaped. The guide groove 9 may include a starting end 91 near the outer wall 31 of the door body 3 and a terminating end 92 near the inner wall 32 of the door body 3. The terminating end 92 is close to the rotation axis of the door body 3 relative to the starting end 91.

[0033] The widths of the first wiring channel 63 and the second wiring channel 73 can be configured to match the connecting conduit 10. The guide block 74 can be cylindrical to allow for smoother sliding within the guide groove 9. The first end 61, the second end 62, the third end 71, and the fourth end 72 can all be provided with openings for the wiring of the connecting conduit 10, so that the connecting conduit 10 can pass through the opening of the first end 61 into the first wiring channel 63 from inside the housing 2, then exit the first wiring channel 63 through the opening of the second end 62, then enter the second wiring channel 73 through the opening of the third end 71, and finally exit the second wiring channel 73 through the opening of the fourth end 72 to enter the interior of the housing 3.

[0034] Since the guide groove 9 is set on the door body 3, when the door body 3 is opened, the guide groove 9 moves relative to the guide block 74 in the opening direction and gradually moves away from the box body 2.

[0035] Since the fixed wiring box 6 is fixedly installed on the housing 2, and the movable wiring box 7 is rotatably connected to the fixed wiring box 6, while the guide groove 9 moves relative to the guide block 74, the guide block 74 of the movable wiring box 7 gradually slides within the guide groove 9 under the limitation of the guide groove 9, and the third end 71 of the movable wiring box 7 rotates relative to the second end 62 of the fixed wiring box 6.

[0036] The guide groove 9 can be used to define the sliding trajectory of the guide block 74. In other embodiments, the guide groove 9 can be an inclined line. However, in this embodiment, the guide groove 9 is arc-shaped rather than linear, which has the following advantages.

[0037] First, the arc-shaped guide groove 9 fits the sliding trajectory of the guide block 74 better, which can reduce the wall friction between the guide groove 9 and the guide block 74, making the guide block 74 slide more smoothly, while avoiding the force between the guide block 74 and the guide groove 9 from affecting the opening and closing of the door 3.

[0038] Secondly, when the guide block 74 slides the same distance, the rotation angle of the movable wiring box 7 sliding along the arc trajectory is smaller than that of the fixed wiring box 6. Therefore, it can effectively reduce the swing angle of the movable wiring box 7 relative to the fixed wiring box 6, and prevent the connecting pipeline 10 between the movable wiring box 7 and the fixed wiring box 6 from being broken or damaged due to the frequent large swing angle of the movable wiring box 7.

[0039] Third, under the same maximum opening angle, the arc-shaped guide groove 9 can ensure that the movable wiring box 7 has a certain length while occupying less space in the door body 3. This ensures that the movable wiring box 7 can effectively guide the wiring of the connecting pipe 10 while improving the utilization rate of the space in the door body 3 and preventing interference with other structures on the door body 3.

[0040] Therefore, the design scheme of this embodiment can facilitate the routing of the connecting pipe 10 between the box 2 and the door 3, avoid affecting the normal opening and closing of the door 3 due to the routing of the connecting pipe 10, reduce the space occupied by the door 3, improve the space utilization of the door 3, avoid mutual interference of the internal structure of the door 3 due to the routing, prevent the connecting pipe 10 in the routing module from breaking or being damaged due to opening and closing the door, and improve the service life of the connecting pipe 10.

[0041] Reference Figure 2 and Figure 3 Furthermore, in another embodiment of the present invention, when the door 3 is closed on the box 2, the guide block 74 is located at the starting end 91 of the guide groove 9, and the width of the guide groove 9 at the starting end 91 can be 1.5 to 3 times the width of the guide block 74.

[0042] Of course, in other embodiments, the width ratio of the guide groove 9 and the guide block 74 can also be other values.

[0043] Since the guide block 74 is also stationary when the door 3 is in a closed, static state, a large frictional force is easily generated between the guide block 74 and the guide groove 9 when the door 3 is suddenly pulled open. Therefore, increasing the width of the guide groove 9 can provide more room for the guide block 74 to move, thus avoiding strong friction between the guide block 74 and the guide groove 9.

[0044] In addition, since the connecting cable 10 of the movable cable box 7 enters and exits the second cable channel 73 from the fourth end 72, i.e. the guide groove 9, if the guide groove 9 is narrow, the distance between the wall of the guide groove 9 and the wall of the fourth end 72 of the movable cable box 7 will be too close, which will easily clamp the connecting cable 10, thereby affecting the sliding fit between the guide block 74 and the guide groove 9, or even causing damage to the connecting cable 10.

[0045] In addition, if the guide groove 9 is too narrow, it will cause the connecting pipeline 10 to swing at a large instantaneous angle, which can easily cause the connecting pipeline 10 to bend or be damaged.

[0046] Therefore, this arrangement provides ample space for the movable wiring box 7 and the connecting pipe 10, increasing their freedom of movement on the door 3, avoiding excessive friction between the movable wiring box 7 and the door 3, and preventing wire clamping or bending between them. It also facilitates the routing of the connecting pipe 10 between the box 2 and the door 3, and extends the service life of the connecting pipe 10.

[0047] Reference Figure 2 and Figure 3 Furthermore, in another embodiment of the present invention, when the door 3 is opened to the maximum preset angle, the guide block 74 is located at the end 92 of the guide groove 9, the guide block 74 slides between the starting end 91 and the end 92, and the width of the guide groove 9 gradually decreases from the starting end 91 to the end 92.

[0048] In this embodiment, the width of the guide groove 9 can always be greater than the width of the guide block 74, and the width of the guide groove 9 can gradually decrease from the starting end 91 to the ending end 92.

[0049] This configuration provides ample space for the movable wiring box 7 and the connecting pipe 10, increasing their freedom of movement on the door 3 while effectively limiting the movement trajectory of the movable wiring box 7. This allows the movable wiring box 7 to better guide the connecting pipe 10, making the wiring path of the connecting pipe 10 more reasonable, and reducing the space occupied by the door 3.

[0050] Reference Figure 2 and Figure 3Furthermore, in another embodiment of the present invention, a hinge 8 is provided between the door body 3 and the box body 2. One end of the hinge 8 is fixedly provided to the box body 2, and the other end is provided with a hinge shaft 81 that is rotatably connected to the door body 3. The rotation axis of the door body 3 is the axis of the hinge shaft 81.

[0051] The fixed cable tray 6 can be installed at the hinge 8. Furthermore, the fixed cable tray 6 can be connected to the hinge 8, and a limiting block or other limiting and connecting structure can be provided between the fixed cable tray 6 and the hinge 8 to make the connection between the fixed cable tray 6 and the housing 2 more stable through the hinge 8 and prevent the fixed cable tray 6 from shaking.

[0052] The rotation axis of the door 3 is located near the side wall of the hinge 8 and the inner wall 32 of the door 3. This arrangement facilitates the rotation of the door 3 relative to the housing 2 and prevents the door 3 structure from colliding with the housing 2.

[0053] Interference occurs between the structures.

[0054] The rotation axis of the movable wiring box 7 is close to the outer wall 31 and rotates relative to the door 3.

[0055] The hinge 8 is located on the side wall with its axis away from the door body 3. The guide groove 9 is located away from the hinge 8 relative to the rotation axis of the movable 5 wiring box 7.

[0056] This design facilitates the cooperation between the wiring module and the door 3, provides sufficient installation and movement space for the wiring module, and avoids interference between the wiring module and the hinge 8.

[0057] The angle between the plane formed by the rotation axis of the movable wiring box 7 and the rotation axis of the door 3 and the plane containing the inner wall 32 is greater than 45 degrees.

[0058] 0. Because the thickness of door body 3 is finite, the width of door body 3 is often much larger than its thickness, leading to...

[0059] The end 92 of the guide groove 9 is close to the inner wall 32 of the door body 3 and closer to the rotation axis of the door body 3, so the guide block 74 can only slide along the guide groove 9. Therefore, the distance between the rotation axis of the movable wiring box 7 and the end 92 actually limits the length of the movable wiring box 7, that is, the length of the connecting pipe 10 that the movable wiring box 7 can guide.

[0060] Furthermore, the longer the movable wiring box 7 is, the smaller the swing angle of the movable wiring box 7 when the door 3 is opened and closed; the shorter the length of the movable wiring box 7 is, the larger the swing angle of the movable wiring box 7 when the door 3 is opened and closed.

[0061] Therefore, the angle between the plane formed by the rotation axis of the movable wiring box 7 and the rotation axis of the door 3 and the plane containing the inner wall 32 is greater than 45 degrees. This ensures the distance between the rotation axis of the movable wiring box 7 and the termination end 92, guarantees the length of the movable wiring box 7, and reduces the sway of the movable wiring box 7 when the door 3 opens and closes.

[0062] The adjustable angle allows the movable cable box 7 to better guide the wiring of the connecting ring, preventing the connecting cable from being bent or damaged.

[0063] Reference Figure 2 and Figure 3 Furthermore, in another embodiment of the present invention, the guide groove 9 may include a first guide arc surface 93 and a second guide arc surface 94 spaced apart, the guide block 74 is located between the first guide arc surface 93 and the second guide arc surface 94, and the radius of curvature of the first guide arc surface 93 is smaller than the radius of curvature of the second guide arc surface 94.

[0064] 5. The sidewalls of the guide groove 9 and the guide block 74 that mate can both be smooth curved surfaces to reduce the number of guide blocks.

[0065] Friction between 74 and guide groove 9.

[0066] The curvature center of the first guide arc surface 93 can be located between the rotation axis of the movable wiring box 7 and the side wall of the hinge 8 of the door body 3, as well as between the rotation axis of the movable wiring box 7 and the rotation axis of the door body 3.

[0067] This design ensures that the side of the guide groove 9 near the movable cable box 7 has an appropriate curvature.

[0068] The radius of curvature is adjusted to ensure that the curvature of the side is neither too small nor too large, so as to better match with the guide block 74 and limit the movement trajectory of the guide block 74.

[0069] The curvature center of the second guide arc surface 94 is located between the curvature center of the first guide arc surface 93 and the rotation axis of the movable wiring box 7, and between the rotation axis of the movable wiring box 7 and the outer wall 31.

[0070] This configuration ensures that the side of the guide groove 9 away from the movable wiring box 7 has an appropriate radius of curvature, and that it forms a circle with the side of the guide groove 9 near the movable wiring box 7 from the starting end 91 to the ending end.

[0071] The guide groove 9, with its gradually decreasing width at the stop end 92, allows the guide groove 9 to better cooperate with the guide block 74 and limit the movement trajectory of the guide block 74.

[0072] Reference Figure 2 and Figure 3 Furthermore, in another embodiment of the present invention, the central angles corresponding to the first guide arc surface 93 and the second guide arc surface 94 are both greater than 45 degrees.

[0073] 5. This configuration ensures that the movable wiring box 7 has sufficient range of motion, guaranteeing the optimal position of the door 3.

[0074] The door opening angle is large to avoid the maximum opening angle of the door body 3 being too small due to the guide groove 9 being too short.

[0075] Furthermore, in this embodiment, the central angles corresponding to the first guide arc surface 93 and the second guide arc surface 94 can be greater than or equal to 55 degrees, and the maximum preset opening angle of the door body 3 can be 130 degrees.

[0076] Furthermore, in this embodiment, the distance between the rotation axis of the door body 3 and the rotation axis O of the movable wiring box 7 can be between 35mm and 55mm. The connecting conduit 10 can be located between the rotation axis of the door body 3 and the movable...

[0077] Cables are routed between the rotation axes of the wiring box 7.

[0078] This configuration ensures sufficient wiring space 36 between the wiring module and the rotation axis, preventing the sliding module from sliding when the door is opened due to excessive distance between the rotation axis of the movable wiring box 7 and the rotation axis of the door body 3.

[0079] The required sliding distance is too long, while ensuring that the length of the movable wiring box 7 is not too short, thus reducing the swing angle of the movable wiring box 7 when the door 5 3 is opened and closed.

[0080] Furthermore, in this embodiment, the distance between the inner wall 32 and the outer wall 31 can be greater than or equal to 90 mm. The width of the door 3 is less than or equal to 430 mm.

[0081] The door body 3 may have a control board 35 for controlling the chilled water module on the side of the wiring module away from the hinge 8. The control board 35 may have a wiring space 36 for connecting the pipeline 10 at a distance from the inner wall 32 of the door body 3.

[0082] The distance between the rotation axis of the movable wiring box 7 and the outer wall 31 can be less than 40mm. The distance between the rotation axis of the movable wiring box 7 and the side wall of the hinge 8 of the door body 3 can be less than 50mm. The distance between the starting end 91 and the outer wall 31 can be less than 20mm. The distance between the guide block 74 and the rotation axis of the movable wiring box 7 is between 45mm and 75mm.

[0083] Furthermore, in this embodiment, the radius of curvature of the first guide arc surface 93 can be 15-30 mm larger than the distance between the rotation axis of the guide block 74 and the movable wiring box 7. The radius of curvature of the second guide arc surface 94 can be 10-25 mm larger than the radius of curvature of the first guide arc surface 93.

[0084] This configuration allows the wiring module to be centrally located at the hinge 8, reducing the space occupied by the movable wiring box 7 in the width direction of the door 3. It ensures the opening angle of the door 3 while maintaining the appropriate length of the movable wiring box 7, and ensuring the appropriate swing angle of the movable wiring box 7 when the door 3 is opened and closed. This allows the guide groove 9 to better cooperate with the guide block 74, limiting the movement trajectory of the guide block 74.

[0085] Reference Figure 2 and Figure 3 Furthermore, in this embodiment, the door body 3 is provided with a first accommodating area 34 and a cover covering the first accommodating area 34 at its end. The hinge shaft 81, the fixed wiring box 6, the movable wiring box 7, and the guide groove 9 are all provided in the first accommodating area 34. The first accommodating area 34 is provided with a connecting part 33 for connecting the cover. The connecting part 33 is provided on the wall surface of the first accommodating area 34 facing the hinge 8 of the door body 3, and / or on the wall surface of the first accommodating area 34 near the inner wall 32.

[0086] This design avoids the wiring module being exposed on the outside of the door body 3, allows for a more reasonable arrangement of the connecting part 33 of the cover, avoids interference with the wiring module, and reduces the space occupied in the width direction of the door body 3.

[0087] In summary, the refrigerator 1 of the present invention, by providing a movable wiring box 7 with a guide block 74 rotatably connected to the cabinet 2, and an arc-shaped guide groove 9 formed on the door 3 that cooperates with the guide block 74, can solve the problem that the connection of all wiring between the door 3 and the cabinet 2 cannot be achieved by the hinge due to the size of the hinge shaft.

[0088] The technical solution in this application facilitates the routing of the connecting pipe 10 between the housing 2 and the door 3, avoids affecting the normal opening and closing of the door 3 due to the routing of the connecting pipe 10, reduces the space occupied by the door 3, improves the space utilization of the door 3, prevents the connecting pipe 10 in the wiring module from being pinched, broken, or damaged due to opening and closing the door, and improves the service life of the connecting pipe 10. In addition, the wiring module can be centrally located at the hinge 8, reducing the space occupied by the movable wiring box 7 in the width direction of the door 3. It can ensure the opening angle of the door 3 while ensuring that the length of the movable wiring box 7 is appropriate, and ensure that the swing angle of the movable wiring box 7 is appropriate when the door 3 is opening and closing. It can also make the guide groove 9 on the door 3 better cooperate with the guide block 74 of the movable wiring box 7, so that the guide groove 9 can better limit the movement trajectory of the guide block 74 and reduce the friction between the guide groove 9 and the guide block 74.
