Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of refrigerators, in particular to a built-in refrigerator. Background Art
[0002] With the improvement of living standards, people have higher and higher aesthetic requirements for decoration and home appliances. Therefore, built-in refrigerators are accepted and adopted by more and more people because they can be embedded in the cabinet and are more consistent with the cabinet in appearance.
[0003] The lighting, atmosphere lighting and other live components on the door need to be connected to the wiring harness on the cabinet. However, the rotating hinges used between the door and the cabinet of existing built-in refrigerators are different from traditional hinges. When the refrigerator is opened, the door and the cabinet will not only rotate relative to each other, but also move. There is no fixed rotating shaft, which makes the traditional wiring device for guiding the wiring harness on the cabinet into the door unusable. Utility Model Content
[0004] Based on this, the utility model provides a built-in refrigerator to solve the above technical problems.
[0005] A built-in refrigerator comprises: a box body, a first accommodating cavity is configured on the top of the box body, a first wire passing opening is provided on the cavity wall of the first accommodating cavity, a wire guide is provided in the first accommodating cavity, and a wire groove is provided in the wire guide; a box door is rotatably connected to the box body and moves in a direction away from the box body when rotating, a second accommodating cavity is provided on the top of the box door, a second wire passing opening is provided on the cavity wall of the second accommodating cavity; a wire harness, one end of which extends into the first wire passing opening and is connected to an internal component in the box body, and the other end of which extends into the The second wire passing opening is connected to the internal components in the box door, the path from the first accommodating cavity to the wire trough and the second accommodating cavity is the wiring path, the length of the wiring harness from the first wire passing opening to the second wire passing opening is greater than or equal to the sum of the length of the wiring path and the displacement length of the box door; wherein, a rotating groove is provided on the bottom wall of the second accommodating cavity, one end of the wire guide extends out of the first accommodating cavity and is defined as a rotating end, the rotating end is provided with a frustum protruding downward, and the frustum is rotatably matched with the rotating groove.

In addition, due to the rotational coordination of the rotating groove and the truncated cone, the rotation between the wire fitting and the cavity wall of the second accommodating cavity will be more stable. As the box door rotates and moves, the wire fitting must also rotate and move. Therefore, the coordination of the above-mentioned rotating groove and the truncated cone can allow the wire fitting to rotate around the center of the rotational coordination and limit the wiring harness to a preset position, thereby avoiding problems such as the wiring harness being detached, offset, and interfering with the rotation of the box door.

[0035] See also Figure 1-Figure 7 The utility model provides a built-in refrigerator 100. Although the door 20 will be displaced when rotating relative to the cabinet 10, the wiring harness 30 can be stably extended from the cabinet 10 to the door body by improving the wiring structure.
[0036] See also Figure 1-Figure 2The built-in refrigerator 100 includes a box body 10, a box door 20 and a wiring harness 30. The top of the box body 10 is configured with a first accommodating cavity 12, and a first wire passing opening 121 is provided on the cavity wall of the first accommodating cavity 12. A wire guide 13 is provided in the first accommodating cavity 12, and a wire groove 131 is provided in the wire guide 13; the box door 20 is rotatably connected to the box body 10 and moves in a direction away from the box body 10 when rotating. A second accommodating cavity 22 is provided on the top of the box door 20, and a second wire passing opening 221 is provided on the cavity wall of the second accommodating cavity 22; the wiring harness 30, one end of which extends into the first wire passing opening 121, and is connected to the internal components in the box body 10. The first end of the first accommodating chamber 12 is connected to the second accommodating chamber 22, and the other end extends into the second wire passing opening 221, and is connected to the internal components in the box door 20. The path from the first accommodating chamber 12 to the wire groove 131 and the second accommodating chamber 22 is the wiring path. The length of the wiring harness 30 from the first wire passing opening 121 to the second wire passing opening 221 is greater than or equal to the sum of the length of the wiring path and the displacement length of the box door 20; wherein, a rotating groove 222 is provided on the bottom wall of the second accommodating chamber 22, and one end of the wire guide 13 extends out of the first accommodating chamber 12 and is defined as a rotating end 132. The rotating end 132 is provided with a frustum 133 protruding downward, and the frustum 133 is rotatably matched with the rotating groove 222.
[0037] In this way, the first wire opening 121 on the wall of the first accommodating chamber 12 is used for the wire harness 30 to extend into and facilitate the connection of the wire harness 30 with the internal components of the box body 10, and the second wire opening 221 on the wall of the second accommodating chamber 22 is used to facilitate the connection of the wire harness 30 with the internal components of the box door 20. The wire guide 13 extends from the box body 10 to the box door 20, and the wire harness 30 is routed from the wire groove 131 in the wire guide 13, protected by the wire guide 13, and extends along the wire groove 131, which facilitates the wiring of the wire harness 30 extending from the box body 10 to the box door 20. And because the length of the wire harness 30 is greater than the sum of the length of the routing path from the first wire opening 121 to the wire groove 131 and then to the second wire opening 221 and the displacement distance of the box door 20, although displacement will occur with the rotation of the box door 20, extending the original routing path, the length of the wire harness 30 can still meet the working conditions. In addition, due to the rotational coordination of the rotating groove 222 and the truncated cone 133, the rotation between the wire guide 13 and the cavity wall of the second accommodating cavity 22 will be more stable. As the box door 20 rotates and moves, the wire guide 13 must also rotate and move. Therefore, the coordination of the rotating groove 222 and the truncated cone 133 can allow the wire guide 13 to rotate around the center of the rotational coordination and limit the wiring harness 30 to a preset position, thereby avoiding problems such as the wiring harness 30 being detached, offset, and interfering with the rotation of the box door 20.
[0038] See also Figure 6Furthermore, a first abutting protrusion 134 is radially protruded outward on the outer peripheral wall of the truncated platform 133, and the first abutting protrusion 134 extends along the circumferential direction of the outer peripheral wall of the truncated platform 133, and the outer wall of the first abutting protrusion 134 abuts against the groove wall of the rotating groove 222. In this way, the truncated platform 133 and the rotating groove 222 are abutted and limited in the circumferential direction through the first abutting protrusion 134 to ensure the relative rotational cooperation between the two. The first abutting protrusion 134 can reduce the contact area between the truncated platform 133 and the groove wall of the rotating groove 222, thereby reducing friction, and because it extends along the circumferential direction, although the abutting area is reduced, it can still ensure a sufficient circumferential cooperation effect.
[0039] See also Figure 7 Furthermore, the groove wall of the rotating groove 222 is provided with a second abutting protrusion 2221 radially inwardly protruding, and the second abutting protrusion 2221 extends circumferentially along the groove wall of the rotating groove 222, and the radial inner side of the second abutting protrusion 2221 abuts against the outer circumferential wall of the truncated platform 133. In this way, the second abutting protrusion 2221 further ensures the tightness of the matching between the groove wall of the rotating groove 222 and the truncated platform 133, ensuring that the truncated platform 133 will not deflect during the matching process with the rotating groove 222, thereby causing problems such as jamming or interference.
[0040] Furthermore, along the axial direction of the truncated table 133, the first abutting protrusion 134 and the second abutting protrusion 2221 are arranged at intervals. In this way, the first abutting protrusion 134 and the second abutting protrusion 2221 are arranged in an axially staggered manner, so when the truncated table 133 and the rotating groove 222 rotate relative to each other, the first abutting protrusion 134 and the second abutting protrusion 2221 will not interfere with each other, and can provide abutting effects at different positions in the axial direction, that is, the truncated table 133 is subjected to different abutting forces during the rotation process, so as to further ensure its rotation stability.
[0041] It can be understood that in other embodiments, a third abutment protrusion (not shown in the figure) or a fourth abutment protrusion (not shown in the figure) can be added to the groove wall of the table 133 and / or the rotating groove 222 to provide a more stable rotation limiting effect, which is not limited to the above-mentioned first abutment protrusion 134 and second abutment protrusion 2221.
[0042] Specifically, the angle of the center angle corresponding to the arc edge from one end to the other end of the first abutment protrusion 134 in the circumferential direction is defined as the first angle, and the angle of the center angle corresponding to the arc edge from one end to the other end of the second abutment protrusion 2221 in the circumferential direction is defined as the second angle, so that the sum of the first angle and the second angle is less than or equal to 360°, that is, the sum of the two angles is less than one circle. Therefore, during the assembly process of the first abutment protrusion 134 and the second abutment protrusion 2221 in the axial direction, avoidance can be formed by rotation to avoid the sum of the angles of the two being greater than 360°. In this case, the two will inevitably have overlapping parts in the axial direction, causing problems in assembly.
[0043] Furthermore, for the convenience of injection molding and demoulding, the bottom of the rotating groove 222 has an opening 2222 , and the opening 2222 and the second abutting protrusion 2221 are correspondingly arranged in the axial direction.
[0044] In this embodiment, a boss 223 is provided on the cavity wall of the second accommodating cavity 22, and a circular hollow is provided in the middle of the boss 223 to form a rotation groove 222. In other embodiments, the rotation groove 222 can also be directly opened on the cavity wall of the second accommodating cavity 22.
[0045] See also Figure 6 , the outer wall of the rotating end 132 of the wire guide 13 is arc-shaped, and the rotating end 132 of the wire guide 13 is provided with a wire groove 1321; the wire guide 13 includes a bottom plate 136, a side plate 135 and a wire cover 137, both sides of the bottom plate 136 are connected to the side plates 135, the bottom plate 136 and the side plates 135 are arranged to form the wire groove 131, and the wire cover 137 is covered on the upper ends of the two side plates 135 away from the bottom plate 136. The wire guide 13 is set to an arc shape to reduce the interference between the outer side wall and other components during its rotation, and it is also convenient for it to be formed together with the truncated table 133, simplifying the processing flow. And the wire groove 1321 provided at the rotating end 132 of the wire guide 13 is used to facilitate the passage of the wire harness 30, and the wire harness 30 passes through the wire groove 1321 and extends toward the second wire opening 221. The wire harness 13 is composed of a bottom plate 136, a side plate 135 and a wire cover 137, which can be processed separately and then assembled together, with low processing difficulty, and the wire harness 30 can be more conveniently arranged in the wire groove 131. After the wire cover 137 is covered on the upper ends of the two side plates 135, the bottom plate 136, the side plates 135 and the wire cover 137 can be surrounded to form a protective space for the wire harness 30, so as to ensure the protective effect of the wire harness 30 without hindering the assembly of the wire harness 30 in the wire groove 131.
[0046] Of course, it is understandable that in other embodiments, the wire member 13 can also be directly integrally formed to obtain higher structural strength and higher processing efficiency, and the wiring harness 30 can be assembled by passing it through one end of the wire member 13 and then passing it out from the other end.
[0047] The wire guide 13 further includes a plurality of reinforcing ribs 138, one side of the reinforcing rib 138 is connected to the bottom plate 136, and the other side is connected to the side plate 135, and the plurality of reinforcing ribs 138 are evenly arranged along the length direction of the wire guide 13. In this way, the reinforcing ribs 138 can improve the connection strength and structural strength between the side plate 135 and the bottom plate 136. The top of the box 10 is provided with a first wiring harness box 11, which is hollow, and the space inside the first wiring harness box 11 is the first accommodating chamber 12; the top of the door 20 is provided with a second wiring harness box 21, which is hollow, and the space inside the second wiring harness box 21 is the second accommodating chamber 22; the built-in refrigerator 100 includes at least two doors 20, and the two doors 20 are rotatably connected to both sides of the width direction of the box 10 in the form of double doors, each door 20 is provided with a second wiring harness box 21, and two first wiring harness boxes 11 are provided on the top of the box 10, and each first wiring harness box 11 is correspondingly connected to a second wiring harness box 21. In this way, the formation of the first accommodating chamber 12 and the second accommodating chamber 22 is more convenient, and the two first wiring harness boxes 11 serve the two doors 20 respectively, even if one of them fails, the live components on the other door 20 can still be used.
[0048] In other embodiments, the first accommodating chamber 12 may be directly opened on the top of the box body 10, and the second accommodating chamber 22 may be directly opened on the top of the box door 20, and is not limited to the above-mentioned implementation of the first wiring harness box 11 and the second wiring harness box 21. When there is only one door 20, only one first wiring harness box 11 is required.
[0049] See also Figure 3-Figure 5 Further, the first wiring harness box 11 includes a first box body 111 and a first cover body 112, the first box body 111 and the first cover body 112 are connected, and a slide groove 113 is opened on the side of the first box body 111 close to the box door 20, the width of the slide groove 113 is greater than the width of the wire member 13, and one end of the wire member 13 extends from the slide groove 113; the second wiring harness box 21 includes a second box body 211 and a second cover body 212, the second box body 211 and the second cover body 212 are connected, and the second box body 211 has a groove on the side close to the box body 10, and the wire member 13 extends into the second accommodating cavity 22 from the groove.
[0050] In this way, since the door 20 will inevitably be displaced during the rotation process, although the wire guide 13 can rotate around the rotation center of the remaining rotation grooves 222, it will also be displaced with the door 20. Therefore, the opening of the slide groove 113 can keep most of it in the first accommodating chamber 12 during the displacement process. The width of the slide groove 113 is greater than the width of the wire guide 13, which provides space for its free rotation and movement, and can avoid interference between the wire guide 13 and other structures. In addition, the first wiring harness box 11 and the second wiring harness box 21 can protect the wiring harness 30, cover the various structural elements in the first accommodating chamber 12 and the second accommodating chamber 22, and provide a beautiful, simple and elegant appearance.
[0051] The first harness box 11 and the second harness box 21 are both provided with a plurality of fixing seats 114. The fixing seats 114 in the first harness box 11 are connected to the inner wall of the first harness box 11 and are clamped with the harness 30. The fixing seats 114 in the second harness box 21 are connected to the inner wall of the second harness box 21 and are clamped with the harness 30. The fixing seats 114 are used to clamp the harness 30, ensure the extension route of the harness 30, enable the harness 30 to extend or retract along the preset routing path, and avoid the problems of disorder of the harness 30.
[0052] Compared with the prior art, the utility model optimizes the routing path of the wire harness 30 and extends the length of the wire harness 30 so that it has a reserved section in the first accommodating cavity 12. As the door 20 rotates and moves, the wire harness 30 can follow it and extend, and ensure a stable electrical connection between the door 20 and the box body 10. The wiring of the wire harness 30 is guided by the wire guide 13, and a wire groove 131 is provided to rotate with the round table 133 on the wire guide 13, so as to ensure the stable position of the wire guide 13.
[0053] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0054] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
