Description

Technical Field

[0001] This application relates to the field of home appliance technology, and more particularly to a refrigerator. Background Technology

[0002] As an indispensable home appliance in modern families, refrigerators have become increasingly sophisticated and functional with the development of technology to meet users' needs for food preservation, storage, and other aspects. Their internal wiring requires various cables, such as power lines for components like fans, lights, and sensors.

[0003] In the process of conceiving and implementing this application, the applicant discovered at least the following problems: In order to meet the needs of large volume ratio, the thickness of the foam layer in current refrigerators is getting thinner and thinner, and the wiring harness plug-in board is also required to be thinner and thinner. The traditional wiring harness appears from the back of the wiring harness plug-in board, which occupies a large space and is prone to condensation.

[0004] The preceding description is intended to provide general background information and does not necessarily constitute prior art. Utility Model Content

[0008] The wiring assembly, assembled in the mounting section, includes:

[0009] The junction box has the following features:

[0010] Receptacle;

[0011] The cable outlet is connected to the receiving cavity and is located on the side wall of the circuit box.

[0012] The wiring terminal is housed in the receiving cavity;

[0013] The cable is housed in the housing cavity and electrically connected to the terminal block. The cable extends through the outlet and extends along the depth of the housing.

[0027] In some alternative implementations, the circuit box includes:

[0028] A base, fitted onto the mounting section, has an opening;

[0029] A rotating cover is rotatably positioned at the opening. When the rotating cover is positioned at the opening, a first limiting groove is formed between the rotating cover and the base. The first limiting groove is connected to the receiving cavity, and at least a portion of the cable is received within the first limiting groove.

[0030] The above technical solution has the following advantages or beneficial effects: the rotatable cover makes it extremely convenient to perform wiring, inspection or replacement operations inside the circuit box without disassembling the entire circuit box.

[0032] The first fastener is located on the base;

[0033] The rotating cover has a slot, and the first fastener engages with the slot.

[0034] The above technical solution has the following advantages or beneficial effects: the cooperation between the buckle and the slot ensures that the rotating cover can be firmly locked after closing, and will not pop open due to vibration or accidental contact, thus ensuring the safety of the internal components of the circuit box.

[0035] In some alternative implementations, the circuit assembly further includes:

[0036] The second fastener is located on the base;

[0037] The wiring terminal is secured to the base by a second locking element.

[0038] The above technical solution has the following advantages or beneficial effects: the second fastener fastens the wiring terminal onto the base, preventing it from shaking or loosening in the receiving cavity, thus ensuring the stability and reliability of the electrical connection.

[0039] In some alternative implementations, the circuit assembly further includes:

[0040] The adhesive connector is used to attach the terminal block to the junction box.

[0041] The above technical solutions have the following advantages or beneficial effects: adhesives (such as double-sided tape) are low in cost, flexible in application, and have lower requirements for the structural design of the circuit box, providing options for different cost and design needs.

[0042] In some alternative embodiments, the circuit box has a second limiting groove, which is bent and communicates with the receiving cavity, and the cable is received in the second limiting groove.

[0043] The above technical solution has the following advantages or beneficial effects: the bent limiting groove can guide the cable to the outlet in a more compact and reasonable path, further optimizing the cable layout in a limited space and avoiding unnecessary bending.

[0044] The refrigerator provided in this application includes a refrigerator body, comprising: a cabinet having an inner liner, the inner liner having a mounting portion; a wiring assembly assembled in the mounting portion, the wiring assembly including: a wiring box having: a receiving cavity; a cable outlet communicating with the receiving cavity and the cable outlet being opened on the side wall of the wiring box; a terminal block being received in the receiving cavity; and a cable being received in the receiving cavity and electrically connected to the terminal block, the cable extending through the cable outlet and extending along the depth direction of the cabinet body.

[0045] By integrating the terminals and cables within the junction box to form an independent modular component, rapid installation on the inner liner of the box is achieved, greatly improving production efficiency and assembly consistency.

[0069] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. All other obtained embodiments are within the scope of protection of this application. In the absence of conflict, the following embodiments and features can be combined with each other.

[0070] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0071] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0072] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of this application.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0073] In order to meet the needs of large volume ratio, the thickness of the foam layer in modern refrigerators is getting thinner and thinner, which also requires the wiring harness and power strip to be thinner. Traditional wiring harnesses appear from the back of the wiring harness and power strip, taking up a lot of space and making them prone to condensation.

[0074] To overcome the shortcomings of existing technologies, the refrigerator provided in this application integrates the wiring terminals and cables into a wiring box, forming an independent modular component. This enables rapid installation on the inner liner, greatly improving production efficiency and assembly consistency. Furthermore, the wiring box's accommodating cavity effectively organizes the wiring terminals and cable routing. The lateral cable outlet, combined with the depth-oriented extension path, allows the cables to be arranged close to the inner wall, minimizing the overall space required and avoiding interference with other components, thus preventing condensation.

[0075] The contents of this application will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can have a clearer and more detailed understanding of the contents of this application.

[0077] like Figures 1 to 11 As shown, this application embodiment provides a refrigerator 100, including:

[0078] The enclosure 110 has an inner liner 111, and the inner liner 111 has a mounting part 1111;

[0079] Line assembly 120, assembled in mounting section 1111, includes:

[0080] Line box 121 has:

[0081] Receiving cavity 1201;

[0082] The cable outlet 1202 is connected to the receiving cavity 1201, and the cable outlet 1202 is located on the side wall of the circuit box 121.

[0083] Terminal 122 is accommodated in receiving cavity 1201;

[0084] Cable 123 is housed in receiving cavity 1201 and electrically connected to terminal block 122. Cable 123 extends out through outlet 1202 and extends along the depth direction of housing 110.

[0085] Through the above-described configuration, namely the refrigerator 100 of this embodiment, by integrating the terminal block 122 and the cable 123 into the wiring box 121 to form an independent modular component, rapid installation on the inner liner 111 is achieved, greatly improving production efficiency and assembly consistency. Furthermore, the receiving cavity 1201 of the wiring box 121 effectively regulates the routing of the terminal block 122 and the cable 123. The lateral cable outlet 1202, combined with the depth-direction extension path, allows the cable 123 to be arranged close to the inner wall, minimizing the overall space occupied and avoiding interference with other components.

[0086] It should be noted that the following provides a detailed explanation of each structure.

[0087] [Box 110]

[0088] The refrigerator 100 of this application embodiment may include a cabinet 110 and a door 130. The cabinet 110 may be configured with a refrigeration compartment. The refrigeration compartment has an opening for storing food and other items. There may be one or more refrigeration compartments. When there are multiple refrigeration compartments, the multiple refrigeration compartments may be divided into a refrigerator compartment, a freezer compartment, or a variable temperature compartment, etc.

[0089] For example, the refrigerator body 110 may include an outer shell and an inner liner 111, the outer shell defining the external boundary of the refrigerator 100. The inner liner 111 may be disposed inside the outer shell and connected to the outer shell. The inner liner 111 may be recessed inward to form a cooling compartment. An insulation layer may be filled between the outer shell and the inner liner 111, the insulation layer insulating the cooling compartment, thereby reducing the energy consumption of the refrigerator 100.

[0090] The box 110 adopts a hollow cuboid structure. It is understood that in other embodiments, the box 110 may also adopt a hollow shell structure of other shapes.

[0091] It should be noted that the refrigerator 100 also includes a refrigeration component, which is used to provide cooling for the interior of the refrigerator 100 in order to maintain a low temperature environment in each refrigeration compartment.

[0092] In some embodiments, the refrigeration assembly includes a compressor, condenser, evaporator, throttling device, etc. The specific structure and connection relationships of the refrigeration assembly can be found in related art, and will not be repeated here. The evaporator provides different amounts of cooling capacity to different types of storage spaces, resulting in different temperatures within these spaces. For example, the temperature inside a refrigerator compartment is generally between 2°C and 10°C, preferably between 4°C and 7°C. The temperature range inside a freezer compartment is generally between -22°C and -14°C.

[0093] Different types of items have different optimal storage temperatures, and consequently, different suitable storage spaces. For example, fruits and vegetables are best stored in the refrigerator or crisper drawer, while meat is best stored in the freezer.

[0094] It should be noted that X represents the depth direction of the box 110, Y represents the width direction of the box 110, and Z represents the height direction of the box 110.

[0095] [Gate 130]

[0096] It should be noted that the door 130 can be connected to the cabinet 110 to open or close the refrigeration compartment.

[0097] A door 130 is disposed on the front surface of the enclosure 110 to enclose the refrigeration compartment. The door 130 is configured to open and close the refrigeration compartment, meaning it can open and close the front opening of the enclosure 110. Doors 130 can be correspondingly assigned to refrigeration compartments, meaning each refrigeration compartment has one or more doors 130. The number of refrigeration compartments and doors 130, as well as the function of the refrigeration compartments, can be selected based on specific circumstances. One door 130 can be assigned to the same refrigeration compartment. Alternatively, two doors 130 can be assigned to the same refrigeration compartment.

[0098] In some possible implementations of this application, the door 130 can be rotatably connected to the housing 110 about the height direction Z of the housing 110. The door 130 can be pulled or pushed so that the door 130 rotates relative to the housing 110 to open or close the refrigeration compartment.

[0099] In some embodiments, the door 130 is a rotating door structure. The door 130 is rotatably disposed on the front side of the housing 110, and in this case, the door 130 can be used as a general door structure, such as a refrigerator door, a variable temperature door, etc.

[0100] Specifically, the door 130 and the cabinet 110 can be connected by a hinge so that the door 130 of the refrigerator 100 can rotate around the axis of the hinge to open and close the door 130, thereby opening and closing the corresponding refrigeration compartment.

[0101] In some embodiments, the door 130 can also be a sliding door structure. The door 130 is slidably disposed on the front side of the cabinet 110, and in this case, the door 130 can be used as a drawer door. Specifically, guide rails (not shown in the figure) are respectively provided on the left and right inner side walls of the cabinet liner, and the door 130 is connected to the guide rails on both sides, thereby realizing the sliding function of the door 130 and realizing the opening and closing of the refrigeration compartment by extending and retracting the guide rails.

[0102] [Line Component 120]

[0103] It should be noted that the refrigerator 100 also includes a wiring assembly 120. By directly assembling the wiring assembly 120 into the pre-set mounting part 1111 of the inner liner 111, quick and accurate positioning and installation are achieved, avoiding the cumbersome process of fixing multiple parts separately in the traditional method and reducing assembly errors.

[0104] The electrical connection components, such as the terminal block 122 and the cable 123, are integrated into a single circuit box 121, which facilitates production, assembly, and maintenance, and improves production efficiency.

[0105] The receiving cavity 1201 of the junction box 121 provides a protective space for the connection points of the terminal block 122 and the cable 123, preventing the cable 123 from being messy inside the box 110 and improving the internal cleanliness and safety.

[0106] Furthermore, the terminal block 122 (e.g., a terminal strip) and the cable 123 are housed within the receiving cavity 1201 of the wiring box 121. One end of the cable 123 is electrically connected to the terminal block 122, and the other end extends through the outlet 1202. Importantly, the extended cable 123 is arranged to extend along the depth direction of the cabinet 110 (i.e., towards the rear of the refrigerator 100). This arrangement allows the cable 123 to be routed close to the rear or top wall of the inner liner 111, minimizing the overall space occupied, reducing the cable 123's protrusion into the storage space, avoiding interference with the movement of drawers, shelves, and other components, ensuring safety and saving space.

[0107] It should be noted that the modular wiring assembly 120 centralizes and manages the dispersed electrical connection points in a standardized manner.

[0108] During the final assembly of refrigerator 100, workers can pre-connect cables 123 within the wiring box 121, and then snap the entire assembly onto the inner liner 111 in one go. This simplifies operations within the narrow interior of refrigerator 110, improving production efficiency and quality consistency. The layout of cables 123 exiting from the side wall and extending into the depth direction is carefully considered; it perfectly adapts to the spatial characteristics of the refrigerator 100's interior, ensuring the safety and neatness of the cables 123.

[0109] In some alternative embodiments, the mounting part 1111 is located on the top wall of the inner liner 111;

[0110] The mounting part 1111 is a mounting port that extends through the opposite sides of the top wall.

[0111] The above technical solution has the following advantages or beneficial effects: the installation part 1111 is located on the top wall, which provides convenience for installation operations from the top of the refrigerator 100, and provides a large operating space and good visibility.

[0112] Furthermore, the mounting openings extend through opposite sides of the top wall, allowing the wiring box 121 to be connected across the top wall. This structure better distributes the load from the wiring assembly 120, improving installation stability and structural strength, and preventing deformation or loosening due to single-point stress.

[0113] In some embodiments, the mounting port is rectangular, but other structures are also possible.

[0114] In some embodiments, the inner liner 111 is further provided with a mounting plate 1112, and the wiring assembly 120 is disposed on the mounting plate 1112. The mounting plate 1112 is disposed on the mounting portion 1111 of the inner liner 111.

[0115] For example, the shape of the mounting plate 1112 matches the shape of the mounting part 1111, both being protruding structural members.

[0116] Figure 12 This is a second-view structural schematic diagram of a circuit assembly in a refrigerator provided in an embodiment of this application. Figure 13 This is a schematic diagram showing the circuit box of a circuit assembly in a refrigerator in an open state, as provided in an embodiment of this application. Figure 14 This is a third-view structural schematic diagram of a circuit assembly in a refrigerator provided in an embodiment of this application.

[0117] like Figures 1 to 14 As shown, in some optional embodiments, the circuit box 121 is provided with at least two hooks 124, and the at least two hooks 124 are spaced apart on the circuit box 121 along the depth direction of the housing 110.

[0118] The hook 124 is configured to extend into the installation port and engage with the top wall of the inner liner 111.

[0119] The above technical solution has the following advantages or beneficial effects: The use of hooks 124 eliminates the need for tools such as screwdrivers, significantly improving assembly efficiency and reducing labor costs. At least two hooks 124 are spaced apart along the depth direction, forming multiple fixing points, which effectively prevents the wiring box 121 from warping, shaking, or loosening in the depth direction, ensuring a secure connection.

[0120] In some embodiments, the hook 124 is an elastic structural component that can better absorb and buffer the vibrations generated during the operation of the refrigerator 100 compressor, etc., prevent the hook 124 from fatigue failure due to long-term vibration, and improve the durability of the product.

[0121] In some embodiments, the hook head portion of the latch 124 is designed as an asymmetrical wedge shape. Its gentle incline facilitates insertion, while its locking surface is designed as a plane perpendicular to the top wall or a plane with a slight reverse angle. The gentle incline ensures easy installation, while the vertical or reverse-angled locking surface provides significant resistance to disengagement, requiring a specific tool to release the latch from the release hole. This achieves extreme vibration resistance and prevention of accidental disengagement, making it suitable for applications with extremely high reliability requirements.

[0122] In some embodiments, the wiring box 121 is made of plastic and has an internal receiving cavity 1201. A cable outlet 1202 is provided on one side wall of the wiring box 121, which communicates with the receiving cavity 1201. At least two latches 124 are provided on the bottom of the wiring box 121 facing the top wall of the inner liner 111. These latches 124 are spaced apart along the depth direction (i.e., the front-to-back direction) of the housing 110.

[0123] Of course, there are no strict limits on the specific number of hooks 124; adjustments can be made based on the actual situation.

[0124] In some embodiments, the material of hook 124 can be POM (polyoxymethylene), which has good fatigue durability and self-lubricating properties and an extremely long service life.

[0125] In other embodiments, the hook 124 may be made of TPE / TPU (thermoplastic elastomer): the hook head portion of the hook 124 is coated with a layer of soft rubber using a secondary injection molding process (overmolding). The soft rubber increases friction, provides a quieter snapping process (eliminating the "clicking" sound), and better adapts to uneven surfaces.

[0126] In some alternative embodiments, the hook 124 is a hook 124 having at least two stepped structures.

[0127] The above technical solution has the following advantages or beneficial effects: the multi-step structure is equivalent to setting multiple locking points, which enhances the locking force and locking effect between the hook 124 and the top wall of the inner liner 111, and can effectively resist the pulling or pushing forces from different directions, preventing the circuit box 121 from accidentally falling off.

[0128] Furthermore, the stepped structure can better accommodate potential thickness variations or manufacturing tolerances in the top wall of the inner liner 111. When the wall thickness varies slightly, the hook 124 can be secured on steps of different heights, ensuring reliable fixation and improving production yield and design tolerance.

[0129] In other words, the hook 124 is designed as a multi-stage hook 124 with at least two stepped structures. This structure can adapt to top walls of different thicknesses and provide multi-level locking to prevent it from coming off.

[0130] It should be noted that during assembly, simply align the hook 124 at the bottom of the circuit box 121 with the mounting port and press it down. The hook 124 will then pass through the mounting port and engage with the lower surface of the top wall, thus enabling quick, tool-free installation of the circuit box 121 with extremely high assembly efficiency.

[0131] like Figures 1 to 14 As shown, in some alternative embodiments, the circuit assembly 120 further includes a buffer 125 attached between the inner liner 111 and the circuit box 121.

[0132] The above technical solution has the following advantages or beneficial effects: the buffer 125 fills the gap between the circuit box 121 and the inner liner 111, eliminates the abnormal noise caused by the hard contact collision between the two due to vibration, improves the quiet performance of the refrigerator 100, and improves the user experience.

[0133] In addition, the buffer 125 has a certain sealing function, which can reduce the heat exchange between the cold air inside the box and the area where the wiring box 121 is located, and help prevent condensation from forming around the wiring box 121 due to temperature difference, thus protecting the electrical components.

[0134] Furthermore, the buffer 125 can compensate for minor tolerances in the manufacturing and assembly of parts, avoid scratches or wear caused by direct hard contact between the circuit box 121 and the inner liner 111, and protect the appearance and materials.

[0135] In some embodiments, the main body of the buffer 125 is rectangular, but its outer edge is designed with an outwardly protruding skirt. The thickness of the skirt is slightly less than the thickness of the main body, and its density is lower. When the circuit box 121 is clamped, the main body is compressed for vibration damping, while the skirt undergoes greater deformation, tightly fitting against the top wall surface to form a more perfect sealing ring, providing excellent anti-condensation and sealing effects.

[0136] As Figures 11 to 14 shown, in some alternative embodiments, the wire box 121 comprises:

[0137] a base 1211, assembled on the mounting portion 1111, the base 1211 having an opening;

[0138] a rotating cover 1212, rotatably disposed at the opening. When the rotating cover 1212 covers the opening, a first limiting groove 1214 is formed between the rotating cover 1212 and the base 1211, the first limiting groove 1214 is communicated with the accommodating cavity 1201, and at least part of the cable 123 is accommodated in the first limiting groove 1214.

[0139] The above technical solution has the following advantages or beneficial effects: the rotatably openable cover makes wiring, inspection or replacement operations in the wire box 121 extremely convenient, without disassembling the entire wire box 121.

[0140] Further, the first limiting groove 1214 is specially used for fixing the cable 123 led out from the terminal 122. It can effectively limit the bending radius and movement of the cable 123 at the wire outlet 1202, prevent the connection point between the cable 123 and the terminal 122 from loosening or breaking caused by frequent pulling or bending, play a key "stress relief" role, and greatly prolong the service life of the cable 123.

[0141] In some embodiments, the wire box 121 comprises a base 1211 and a rotating cover 1212. The base 1211 has an upward opening. One end of the rotating cover 1212 is rotatably connected to the base 1211 via a rotating shaft (not marked in the figure), so that the rotating cover 1212 can be opened or closed like a cover. When the rotating cover 1212 is closed, it and the base 1211 together enclose to form a complete accommodating cavity 1201.

[0142] In some embodiments, the cross-section of the first limiting groove 1214 may be an omega shape. On one hand, the cable 123 can be better limited and fixed; on the other hand, it can prevent the foaming material from entering the accommodating cavity 1201 during the foaming process of the inner tank 111 of the box body.

[0143] With continued reference Figures 11 to 14 , in some alternative embodiments, the wire assembly 120 further comprises:

[0144] a first locking member 126, disposed on the base 1211;

[0145] the rotating cover 1212 has a clamping groove 1213, and the first locking member 126 is clamped with the clamping groove 1213.

[0146] The above technical solution has the following advantages or beneficial effects: the cooperation between the buckle and the slot 1213 ensures that the rotating cover 1212 can be firmly locked after being closed, and will not pop open due to vibration or accidental contact, thus ensuring the safety of the internal components of the circuit box 121.

[0147] In some embodiments, the first latch 126 is designed to have a "click" sound or tactile feedback, providing the operator with clear feedback to confirm closure and to help determine whether the assembly is in place.

[0148] In some embodiments, to ensure the stability of the rotating cover 1212 after it is closed, a first latching element 126 (such as an elastic latch) is provided on the base 1211, and a corresponding slot 1213 is provided on the rotating cover 1212. When the rotating cover 1212 is closed, the first latching element 126 will spring in and engage in the slot 1213, which can effectively prevent the rotating cover 1212 from popping open due to vibration.

[0149] For example, there are two first fasteners 126, which are disposed on opposite sides of the base 1211.

[0150] Correspondingly, there are also two slots 1213, which are located on opposite sides of the rotating cover 1212.

[0151] Continue to refer to Figures 11 to 14 In some alternative implementations, the line assembly 120 further includes:

[0152] The second fastener 127 is located on the base 1211;

[0153] The terminal block 122 is snapped onto the base 1211 by the second snap fastener 127.

[0154] The above technical solution has the following advantages or beneficial effects: the second fastener 127 fastens the terminal 122 onto the base 1211, preventing it from shaking or loosening in the receiving cavity 1201, thus ensuring the stability and reliability of the electrical connection.

[0155] In some embodiments, a second latching member 127 is also provided in the receiving cavity 1201 of the base 1211 to fix the terminal block 122. The terminal block 122 can be locked in place by its own structure (such as a bayonet) in cooperation with the second latching member 127, which facilitates quick assembly.

[0156] In some embodiments, in order to better fix the terminal block 122, two second latching members 127 may be designed, with the two second latching members 127 respectively latching the two sides of the terminal block 122, so that the terminal block 122 can be more stably fixed in the receiving cavity 1201.

[0157] Figure 15 This is a first-view structural schematic diagram of another circuit component in a refrigerator provided in an embodiment of this application. Figure 16 This is a second-view structural schematic diagram of another circuit component in a refrigerator provided in an embodiment of this application. Figure 17 This is a third-view structural schematic diagram of another circuit component in a refrigerator provided in an embodiment of this application.

[0158] like Figures 15 to 17 As shown, in some optional embodiments, the line assembly 120 further includes:

[0159] The adhesive connector and terminal block 122 are attached to the junction box 121 via the adhesive connector.

[0160] The above technical solution has the following advantages or beneficial effects: the adhesive (such as double-sided tape) is low in cost, flexible in application, and has lower requirements for the structural design of the circuit box 121, providing options for different cost and design needs.

[0161] In addition, another simple and effective fixing method is provided besides the snap-fit, which is especially suitable for terminal blocks 122 with irregular shapes or where it is inconvenient to set a snap-fit ​​structure.

[0162] In other words, instead of using a second latching member 127, the terminal block 122 can be attached to the bottom wall of the junction box 121 using an adhesive (such as high-strength double-sided tape). This method is simple in structure and low in cost, and is particularly suitable for terminal blocks 122 that are irregularly shaped or small in size.

[0163] like Figures 15 to 17 As shown, in some optional embodiments, the circuit box 121 has a second limiting groove 1215, which is bent and connected to the receiving cavity 1201, and the cable 123 is received in the second limiting groove 1215.

[0164] The above technical solution has the following advantages or beneficial effects: the bent limiting groove can guide the cable 123 to the outlet 1202 in a more compact and reasonable path, further optimizing the layout of the cable 123 in a limited space and avoiding unnecessary bending.

[0165] In addition, the bent structure can more effectively restrict the degree of freedom of cable 123, providing better tensile and torsional resistance than the straight limiting groove, and providing more comprehensive protection for the cable 123 connector.

[0166] In addition, the bent second limiting groove 1215 can also prevent the foaming material from entering the receiving cavity 1201.

[0167] In some embodiments, the second limiting groove 1215 is bent (e.g., L-shaped or S-shaped), with one end leading to the position of the wiring terminal 122 inside the receiving cavity 1201 and the other end leading to the outlet 1202. After the cable 123 is connected to the wiring terminal 122, it can first be embedded in this bent second limiting groove 1215 and then led out.

[0168] The refrigerator provided in this application includes a cabinet with an inner liner, the inner liner having a mounting portion; a wiring assembly assembled in the mounting portion, the wiring assembly including: a wiring box having: a receiving cavity; a cable outlet communicating with the receiving cavity and the cable outlet being opened on the side wall of the wiring box; a terminal block being received in the receiving cavity; and a cable being received in the receiving cavity and electrically connected to the terminal block, the cable extending through the cable outlet and extending along the depth direction of the cabinet.

[0169] By integrating the terminals and cables within the junction box to form an independent modular component, rapid installation on the inner liner of the box is achieved, greatly improving production efficiency and assembly consistency. Furthermore, the junction box's accommodating cavity effectively organizes the routing of terminals and cables. The lateral cable outlets, combined with the depth-oriented extension path, allow cables to be arranged close to the inner wall, minimizing the overall space required and avoiding interference with other components, thus preventing condensation.
