Description

Technical field

[0001] The present application relates to the field of refrigeration appliances, and in particular to a refrigeration appliance with a pipeline extending from a main body to a door. [Background Technology]

[0002] In recent years, the trend of installing household appliances, such as refrigerators, within cabinets has become widespread. This requires a minimal gap between the refrigerator and the cabinet, seamlessly integrating the appliance into the furniture, while also ensuring that the cabinet does not interfere with the opening of the refrigerator door. This places significant demands on refrigerator hinges. Currently, a large proportion of products in the industry utilize variable-track hinges, meaning the hinge axis shifts during the door's opening and closing. This requires adjustments to the wiring extending from the refrigerator's main body to the door. [Summary of the invention]

[0042] In order to provide a further understanding of the purpose, structure, features, and functions of the present application, the present invention is described in detail below with reference to the embodiments.

[0043] The refrigeration appliance 1 described in this embodiment may include a refrigerator, a refrigerator, a freezer, a wine cabinet, etc. For ease of description, in this embodiment, the width direction of the refrigeration appliance 1 is denoted as the x-direction, the depth direction of the refrigeration appliance 1 is denoted as the y-direction, and the height direction of the refrigeration appliance 1 is denoted as the z-direction. In this embodiment, the front-to-back direction refers to the y-direction and its opposite direction, where the front direction refers to the direction facing the user when the refrigeration appliance 1 is in use, the rear direction refers to the direction away from the user when the refrigeration appliance 1 is in use, the top direction refers to the z-direction shown in the figure, and the bottom direction refers to the direction opposite to the z-direction shown in the figure.

[0044] It should be pointed out that Figure 1 A multi-door refrigerator is used as an example for illustration. In actual application, the structure of this embodiment can also be applied to other types of refrigeration appliances 1, such as a side-by-side refrigerator, a single-door refrigerator, etc.

[0045] Please refer to Figures 1 to 4 ,in, Figure 1 This is a three-dimensional schematic diagram of a refrigeration appliance according to an embodiment of the present application; Figure 2 This is a partially exploded perspective diagram of a refrigeration appliance according to an embodiment of the present application; Figure 3 This is a partial schematic diagram of a refrigeration appliance according to an embodiment of the present application, with the door in a closed state; Figure 4 FIG1 is a partial schematic diagram of a refrigeration appliance according to an embodiment of the present application, with the door in an open state.

[0046] The refrigeration appliance 1 , taking a refrigerator as an example, includes a main body 2 having a storage compartment 10 and at least one door 3 arranged in front of the main body 2 .

[0047] The main body 2 of this embodiment defines three storage chambers 20, which can be a refrigeration chamber, a freezer chamber, a zero-degree chamber or a variable-temperature chamber. Figure 1 The storage chamber, which is closed and opened by the two uppermost doors 3a, 3b, is a refrigerated chamber, the temperature of which is in the range of 2°C to 8°C, for example. Figure 1 The storage compartment, opened and closed by the middle door 3c, is a variable temperature room with a temperature range of -20°C to 8°C. The storage compartment, closed and opened by the bottom door 3d, is a freezer compartment with a temperature range of, for example, -18°C to over 20°C below zero. The variable temperature room has a wide temperature range to meet the needs of different users. Users can set the temperature of the variable temperature room according to their needs, allowing it to be used as a refrigerator, freezer, or zero-degree room.

[0048] In this embodiment, Figure 1 The two doors 3a and 3b at the top of the refrigerator 1 can be rotated to open and close. The two doors 3a and 3b are arranged adjacent to each other to jointly close the storage chamber at the top of the refrigerator 1, namely the refrigeration chamber. Figure 1The middle door 3c and the door 3d located below are drawer-type doors that can be pulled out and opened.

[0049] Doors 3 a and 3 b are rotatably connected to the front of the main body 2 via hinges 4 . Figures 2 to 4 Take door 3a as an example to demonstrate. In the following description, door 3a is also referred to as door 3.

[0050] One end of the hinge 4 is connected to the main body 2, and the other end is connected to the door 3. The hinge 3 may include a hinge plate 41 with one end fixed to the main body 2. The other end of the hinge plate 41 extends to the upper part of the door 3 and is rotatably connected to the door 3.

[0051] In one embodiment of the present application, the hinge 4 is arranged such that the rotation axis of the door 3 shifts during opening, i.e., the rotation axis of the hinge 4 shifts along at least one horizontal direction. In particular, during the opening process of the door 3, the side of the door 3 connected to the hinge 4 can undergo a predetermined inward displacement to prevent interference or collision between the door 3 and surrounding equipment (e.g., cabinets) of the refrigeration appliance 1.

[0052] Specifically, the door 3 is provided with a hinge fitting portion 32 that fits with the axis of the hinge 4 (not shown). The hinge fitting portion 32 has a hinge groove 320 extending at least in the width direction x of the refrigeration appliance 1. Thus, the axis of the hinge 4 moves in the hinge groove 320, and the door 3 moves in the opposite direction x from closing to opening at an angle to avoid the cabinet and prevent the cabinet from interfering with the opening of the door 3.

[0053] The refrigeration appliance 1 includes a pipeline 5. The pipeline 5 can be a wire or wiring harness for transmitting electricity, or a pipe for conveying liquids such as water. A portion of the pipeline 5 is located in the main body 2, and a portion is located in the door 3, so that the pipeline 5 extends between the main body 2 and the door 3. The pipeline 5 is typically a flexible pipeline element.

[0054] Both ends of the pipeline 5 may each have a connector 10 to be mated with a matching connector on the main body 2 and the door 3. It should be understood that in other embodiments, the pipeline 5 may further include one or more connectors located between the two connectors 10 when necessary.

[0055] The pipeline 5 passes through the outlet 21 at the top of the main body 2. Figure 3 and Figure 4In the illustrated embodiment, there are multiple bundles of pipelines extending from the outlet 21 of the main body 2. Among them, the pipeline 5a extends from the main body 2 to the door 3 to power the electrical units on the door 2, such as the heating wire of the flip beam located on the door, the lighting or decorative lights, and the sensors such as the proximity sensor for detecting the human body approaching the refrigeration appliance. The pipeline 5b is connected to the temperature and humidity sensor 65 installed in the cover 6. The pipeline 5c is connected to the door opening detection module installed in the cover 6. In other words, a portion of the pipelines leading out from the outlet 21 of the main body 2 extends to the door 3, that is, the pipeline 5a extends to the door 3. Moreover, the pipeline 5a extending to the door 3 is also a plurality of wires. In the following description, the pipeline 5a is also referred to as the pipeline 5.

[0056] In this embodiment, the pipeline 5 extends along the guide mechanism across the main body 2 and the door 3. The pipeline 5 is guided, constrained and covered to a certain extent by the guide mechanism, which is conducive to a more stable arrangement of the pipeline 5 on the refrigeration appliance 1.

[0057] The guide mechanism includes a front guide 8 fixed to the main body 2 and a rotatable guide 9. The pipeline 5 extends from the main body 2 along the front guide 8 toward the door 3. The pipeline 5 then enters the rotatable guide 9 and extends to the door 3. At least one end of the rotatable guide 9 is pivotally connected so that it can rotate when the door 3 moves. The pipeline 5 enters from one end of the rotatable guide 9 and exits from the other end, extending along the length of the rotatable guide 9.

[0058] like Figure 2 As shown, one end of the hinge 4 is fixed to the main body 2, the cover 6 covers the outlet 21 and the hinge 4, and the front guide 8 is located between the hinge 4 and the cover 6 and can be fixed to the hinge plate 41. The rotatable guide 9 is pivotally connected to the front guide 8.

[0059] The upper end of the door 3 forms a recessed portion 31 on the hinge side that cooperates with the hinge 4. The recessed portion 31 is recessed downward from the top surface of the door 3 and is open to the rear side of the door 3. A hinge engaging portion 32 is mounted in the recessed portion 31.

[0060] The upper end of door 3 also forms a receiving groove 33, recessed downward from the door's top surface. Receiving groove 33 communicates with recessed portion 31. One end of a rotatable guide member 9 is pivotally connected to the front guide member 8, while the other end is inserted into and freely swings within receiving groove 33. The pipeline 5 extends from the main body 2 through the rotatable guide member 9 and into receiving groove 33. To minimize exposure of the pipeline, a decorative cover 34 is removably positioned over receiving groove 33.

[0061] It can be seen that the pipeline 5 of the present application solution passes through the cover 6, the front guide 8, and the rotatable guide 9 into the receiving groove 33. The pipeline 5 extends from the main body 2 to the door 3 without almost any exposed pipeline. For users, it is safer and is more conducive to the refrigeration appliance to have a more beautiful appearance.

[0062] In another embodiment of the present application, the front guide 8 can be omitted. The refrigeration appliance includes a rotatable guide 9 at least partially located on the door 3, and the rotatable guide 9 is pivotally connected to the hinge plate 41. During the opening and / or closing process of the door 3, the pipeline 5 passes through the cover 6 and extends along the rotatable guide 9 to the door 3.

[0063] like Figures 5 to 8 As shown, Figure 5 A schematic three-dimensional diagram of a cover according to an embodiment of the present application; Figure 6 This is a partial schematic diagram of a pipeline in a cover according to an embodiment of the present application; Figure 7 A partial schematic diagram of a cover according to an embodiment of the present application; Figure 8 This is a partial schematic diagram of a cover according to an embodiment of the present application from another perspective. The cover 6 includes a top wall 61 for covering the hinge 4 and a side wall 62 disposed around the top wall 61. A fastener, such as a screw, passes through a fastening portion 69 and connects to the main body to secure the cover 6 to the top of the main body 2.

[0064] The structure of the cover 6 provides an accommodation space for accommodating the pipeline 5 .

[0065] from Figure 3 and Figure 4 As can be seen, the pipeline 5 moves within the cover 6 as the door 3 opens and closes. Conversely, the pipeline 5 also moves as the door 3 opens and closes, but in the opposite direction. If the pipelines are not restrained within the cover 6, they will become tangled, which can adversely affect the refrigerator. For example, they can affect the installation of the cover 6 and potentially damage the pipeline 5 when screwing in the cover 6, causing the associated electrical units to malfunction. If the pipelines are rigidly fixed, they can be pulled during the opening and closing of the door 3, potentially causing adverse effects such as disconnection or poor contact of the connector.

[0066] The pipeline 5 includes a connector 10, which allows for connection between different pipeline segments. The lid 6 includes a retaining structure 7 that holds the connector 10 in place. This retaining structure 7 defines a channel 70, within which the connector 10 is movably positioned during the opening and / or closing of the door 3. Thus, the connector is restrained, preventing a cluttered pipeline layout that could affect lid assembly. Furthermore, the connector is movably restrained, allowing it to move with the overall movement of the pipeline, which helps reduce the possibility of disconnection or poor connection due to strain on the pipeline during the opening and / or closing of the door.

[0067] In order to organize the pipeline 5, the pipeline 5 is led out from the outlet 21, passes through the wire buckle 64, passes through the limiting structure 7, and then passes to the front guide 8 and the rotatable guide 9. The section of the pipeline 5 from the outlet 21 to the wire buckle 64 can be considered fixed and immovable.

[0068] The pipeline 5 includes a first pipeline segment 51 and a second pipeline segment 52. In this embodiment, the first pipeline segment 51 can be considered to be the segment extending from the outlet 21 to the passage 70. The first pipeline segment 51 includes a first connection terminal 11. The second pipeline segment 52 extends from the main body 2 to the main body 3. The second pipeline segment 52 includes a second connection terminal 12. The first and second connection terminals 11 and 12 are connected to form the connector 10, thereby electrically connecting the first and second pipeline segments 51 and 52. The first and second connection terminals 11 and 12 can be connected by plugging.

[0069] from Figures 3 and 4 When the door 3 is opened from the closed state, the connector 10 moves in the first direction D1 in the channel 70. Since the second pipeline section 52 of the pipeline 5 is roughly L-shaped when the door is closed, that is, it is bent at nearly 90 degrees, when the door is opened, for example Figure 4 When the door is opened to approximately 90 degrees, the second pipeline segment 52 bends less than when the door is closed. This allows the second pipeline segment 52 to move slightly in the first direction D1, which is aligned with the depth direction y of the refrigeration appliance. The connector 10's movement in the first direction D1 further pushes the first pipeline segment 51, forming more bends in area B to accommodate the remaining length of the pipeline 5. Therefore, in this embodiment, the remaining length of the pipeline 5 generated during the process of opening the door 3 from closed to open is accommodated in the lid 6.

[0070] When the door 3 by Figure 4 When the door 3 is closed from the open position shown, the second pipeline segment 52 gradually bends more, pulling the connector 10 in the second direction D2, gradually removing the excess pipeline in area B. Therefore, as the door 3 moves from opening to closing, the connector 10 moves in the second direction D2 within the passage 70, with the first direction D1 and the second direction D2 being opposite.

[0071] In this embodiment, the connector 10 moves in the channel 70 within a range of about 10 mm, which is substantially within the range of 5 mm to 15 mm (including the end points).

[0072] In order to guide the extension of the pipeline 5, a guide rib 81 is provided on the front guide 8. The guide rib 81 extends obliquely from the main body 2 to the door 3 toward the inner side of the door 3 to guide the bending of the second pipeline segment when the door is opened and closed.

[0073] Due to the low rigidity of water pipes, wires, or wire bundles, the pipeline 5 does not move in a simple linear motion during the opening and closing of the door 3. In addition to moving in the first and second directions D1 and D2, the pipeline 5 may also move in other directions. This other direction is defined herein as a third direction that intersects the first or second direction D1 or D2. During the door opening and closing process, the connector 10 may experience some left and right swing or offset when moving in the first or second direction D1 or D2. This swing or offset ranges from 2 mm to 5 mm (inclusive).

[0074] The limiting structure 7 of this embodiment will be described in detail below. Figures 5 to 8 As shown, the limiting structure 7 includes a first limiting member 7a and a second limiting member 7b. In this embodiment, the limiting structure 7 and the cover 6 are formed in one piece.

[0075] The first stopper 7a and the second stopper 7b are arranged opposite each other and spaced apart to form the channel 70. The installation entrance 700 for the connector 10 to enter the channel 70 faces the top wall 61 of the cover 6. To guide the installation of the connector, the installation entrance 700 tends to expand from the inside of the channel 70 to the outside.

[0076] like Figure 6 As shown, the connector 10 is formed by connecting a first connecting terminal 11 and a second connecting terminal 12. Since the connector 10 may swing left and right or deflect when moving along the first direction D1 or the second direction D2 during the process of opening or closing the door. In order to reduce the possibility that the connection seam between the first connecting terminal 11 and the second connecting terminal is stuck on the first limit member 7a or the second limit member 7b when the connector 10 moves, thereby affecting the opening of the door and the disconnection or poor contact of the connector, the channel 70 extends smoothly at the port at at least one end in the moving direction of the connector 10 (the first direction D1 or the second direction D2). The channel 70 of this embodiment extends smoothly at the ports at both ends in the moving direction of the connector 10.

[0077] like Figure 7 and Figure 8 As shown, the port at at least one end of the channel 70 in the moving direction of the connector 10 tends to expand from the inside of the channel 70 to the outside. This not only provides space for the connector 10 to swing left and right or deflect during the movement of the pipeline 5, but also reduces the possibility of the connector getting stuck during movement.

[0078] The first limiting member 7 a and the second limiting member 7 b respectively include limiting surfaces 71 facing the connector 10 . The limiting surfaces 71 of the first limiting member 7 a and the limiting surfaces 71 of the second limiting member 7 b are opposite to each other to limit the connector 10 .

[0079] The first limiting member 7 a and the second limiting member 7 b further include a first guiding surface 72 connected to the limiting surface 71 . Along the moving direction of the connector 10 , the first guiding surface 72 extends obliquely outward from the limiting surface 71 .

[0080] like Figure 7 and Figure 8 As shown, the limiting surface 71 of the first limiting member 7a is smoothly connected to the first guide surface 72. The first limiting member 7a in this embodiment is formed on the side wall 62 of the cover 6. The first guide surface 72 of the first limiting member 7a extends smoothly from the limiting surface 71 to the side wall 62. Moreover, the first guide surface 72 extends in an arc shape. During the manufacturing process, the first guide surface 72 is formed on the mold by rounding. Thus, when the connector 10 is swung toward the direction of the first limiting member 7a, the connection between the first guide surface 72 and the limiting surface 71 prevents the connector from being stuck at all.

[0081] The first guide surface 72 of the second stopper 7b includes an inclined surface 721 and a curved surface 722. The first guide surface 72 of the second stopper 7b is formed on the mold by guiding the bevel and the radius. As can be seen, the connection between the first guide surface and the limiting surface of the second stopper 7b is not likely to cause the connector to get stuck.

[0082] The angle between the first guide surface 72 and the limiting surface 71 is in the range of [150°, 170°], which not only provides space for the connector to swing or deflect in the third direction, but also makes it less likely for the connector to be stuck during movement.

[0083] To guide the installation of the connector, the first and second limiting members 7a and 7b are formed with second guiding surfaces 73 at the installation entrance 700 for obliquely guiding toward the channel 70. The second guiding surface 73 of the first limiting member 7a includes an inclined surface 731 and an arc surface 732.

[0084] The second limiting member 7 b forms a hook 76 at the installation entrance 700 , and the hook 76 limits the connector 10 from being separated from the channel 70 from the installation entrance 700 .

[0085] In order to facilitate the insertion of the connector from the installation entrance, the hook 76 also includes a second guiding surface 73 that guides obliquely toward the channel 70 .

[0086] In addition, in order to enhance the elasticity of the hook 76 , the hook 76 extends along a portion of the dimension of the second limiting member 7 b in the moving direction of the connector 10 (the first direction D1 or the second direction D2 ).

[0087] In addition, in order to enhance the connection strength between the first connection terminal 11 and the second connection terminal 12 , the first connection terminal 11 and the second connection terminal 12 are further connected via a snap-fit ​​structure 103 .

[0088] At least one of the first and second connection terminals 11, 12 is provided with a limiter 102. Limiter 102 is retained by limiter structure 7 to limit the maximum distance that connector 10 can move. Considering the range of connector movement during normal door opening and closing, limiter 102 also limits the maximum distance that connector 10 can move, preventing the connector from dislodging from the passageway and, consequently, from the normal wiring path, which could cause the connector's movement during door opening and closing to interfere with other structures within the cover.

[0089] In this embodiment, a limiting portion 102 is provided on the first connecting terminal 11. The limiting portion 102 is located at an end of the first connecting terminal 11 away from the second connecting terminal 12 and comprises two protrusions. The limiting portion 102 abuts against the second limiting member 7b, particularly the hook 73 on the second limiting member 7b, to limit the maximum distance that the connector 10 can move in the first direction D1.

[0090] The second connection terminal 12 is also provided with a limiter 102, located at the end of the second connection terminal 12 away from the first connection terminal 11. The limiter 102 comprises two protrusions. The limiter 102 abuts against the second limiter 7b, particularly the hook 73 on the second limiter 7b, to limit the maximum distance that the connector 10 can move in the second direction D2.

[0091] Combine Figures 1 to 8 The various embodiments of the individual components described may be combined with one another in any given manner to achieve the advantages of the present application.

[0092] This application has been described with reference to the aforementioned embodiments. However, these embodiments are merely exemplary embodiments of the present application. It should be noted that the disclosed embodiments do not limit the scope of this application. On the contrary, modifications and enhancements made without departing from the spirit and scope of this application are intended to be protected by this patent.
