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, in order to meet users' needs for food preservation, storage, and other aspects.

[0003] In conceiving and implementing this application, the applicant discovered at least the following problems: the refrigerator's refrigeration pipes (such as evaporator pipes) typically need to be fixed to the inner liner. Traditional fixing methods often involve fixing the refrigeration pipes to one end of a mounting bracket, while the other end of the bracket is fixed to the inner liner with adhesive. However, adhesive methods suffer from problems such as weak adhesion and susceptibility to aging and failure.

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

[0005] The main objective of this application is to provide a refrigerator in which the fixing components for installing refrigeration pipes are easy to install and reliably connected.

[0006] To achieve the above objectives, this application provides a refrigerator, comprising:

[0007] The enclosure has an inner liner, and the inner liner has an installation port;

[0008] Refrigeration piping;

[0009] Fixed components, including:

[0010] Fasteners are used to secure refrigeration piping.

[0011] A swivel joint is attached to a fixing member and is configured to rotate relative to the mounting port to secure the refrigeration piping to the inner liner of the cabinet.

[0012] The beneficial effects of this application are: through the design of the fixing components, the fixing parts fix the refrigeration pipes, and the rotation operation of the screw connectors can firmly lock the fixing parts with the refrigeration pipes to the installation port of the inner liner of the box. Compared with the adhesive installation, the assembly process is simplified, the production efficiency is improved, and subsequent maintenance and disassembly are convenient, realizing the rapid and reliable installation of the refrigeration pipes.

[0013] Based on the above technical solution, the following improvements can be made to this application.

[0014] In some alternative implementations, there are at least two mounting ports, which are spaced apart along the width of the housing.

[0015] There are at least two fixing components, and the at least two fixing components are spaced apart along the width direction of the housing.

[0016] The above technical solution has the following advantages or beneficial effects: By setting multiple mounting ports and fixing components at intervals along the width of the casing, multi-point and uniform support and fixation of the refrigeration pipeline is achieved. This layout can effectively prevent sagging, vibration or deformation caused by excessively long pipelines, improve the reliability of fixation, ensure the long-term stability of the refrigeration system, and at the same time make the stress distribution more reasonable and avoid local stress concentration.

[0017] In some alternative implementations, the refrigeration piping is in an installed state;

[0018] When the refrigeration piping is in the installation state, the screw-on connector abuts against the outer wall of the inner liner of the box, and the fastener extends into the installation port and is located inside the inner liner of the box.

[0019] The above technical solution has the following advantages or beneficial effects: the screw-on part abuts against the outer wall of the inner liner of the box, and the fixing part extends into the inside of the inner liner of the box, which can ensure that the fixing component is stably anchored on the box wall and is not easy to loosen.

[0020] In some alternative embodiments, the screw-on connector has:

[0021] The mounting surface abuts against the outer wall of the inner liner of the box;

[0022] The fastener is attached to the mounting surface and extends in a direction away from the swivel joint.

[0023] The above technical solution has the following advantages or beneficial effects: The mounting surface abuts against the outer wall of the housing, providing a stable force-bearing foundation for the screw connection. The fasteners extend from the mounting surface, resulting in a compact overall structure and a clear force transmission path. This design optimizes the mechanical properties of the structure, ensuring uniform force distribution during rotation and enhancing the stability and strength of the fixation.

[0024] In some alternative implementations, the inner liner of the box has:

[0025] The abutting part extends toward the mounting opening;

[0026] The fixed components also include:

[0027] A limiting member is provided on the outer periphery of the fixing member. The limiting member has a limiting groove, which has a movement trajectory for the abutting part to move from the first end of the limiting member to the second end of the limiting member, so that the limiting member is screwed onto the inner liner of the box.

[0028] The above technical solution has the following advantages or beneficial effects: the matching design of the limiting groove and the abutment part constitutes a highly efficient and quick snap-fit ​​connection. During assembly, simply place the abutment part into one end of the limiting groove, then rotate the fixing component, and the abutment part will slide along the track to the other end of the limiting groove and lock in place, simplifying the operation and further improving assembly efficiency.

[0029] In some alternative implementations, the limiting member further comprises:

[0030] The limiting surface, when the refrigeration pipeline is in the installation state, is located on opposite sides of the inner liner of the cabinet along the depth direction of the cabinet;

[0031] The limiting surface is the wall of the limiting groove.

[0032] The above technical solution has the following advantages or beneficial effects: It clarifies that in the locked state, the outer wall of the inner liner is tightly clamped between the mounting surface of the screw-on component and the limiting surface of the limiting component. This effectively prevents the fixing components from shaking or loosening in any direction, significantly enhancing the mechanical strength and stability of the fixation.

[0033] In some alternative implementations, the limiting member further comprises:

[0034] A limiting part is located at the second end of the limiting member, and the limiting part extends in the direction facing the mounting surface;

[0035] The limiting part is configured to fix the abutting part to the second end of the limiting member when the abutting part moves to the second end of the limiting member.

[0036] The above technical solution has the following advantages or beneficial effects: the limiting part acts as a stop when the abutting part moves to the end of the limiting groove. The limiting part extends from the second end toward the mounting surface, forming a physical barrier (similar to a protrusion). When the abutting part slides into the second end of the limiting groove during rotation, it can prevent the abutting part from continuing to rotate.

[0037] In some alternative implementations, the fixing component further includes:

[0038] A stop member is provided on the mounting surface, and the stop member protrudes towards the first end of the limiting member along the depth direction of the housing. The stop member is configured to block the abutment portion from moving along the second direction when the abutment portion moves along the first direction to the second end of the limiting member.

[0039] Among them, the first direction and the second direction are two opposite directions.

[0040] The above technical solution has the following advantages or beneficial effects: the limiting part is located at the second end of the limiting groove to prevent the abutting part from coming out. The blocking part is located at the first end of the limiting groove to prevent the abutting part from retracting, thereby fixing the abutting part in the limiting groove.

[0041] In some alternative embodiments, the fastener has:

[0042] The slot is used to accommodate the refrigeration piping.

[0043] The above technical solution has the following advantages or beneficial effects: the slot provides a dedicated space for accommodating and positioning the refrigeration piping. This not only more reliably holds or clamps the piping, preventing it from slipping out of the fastener, but also avoids hard friction or compression between the piping and the fastener, thus protecting the piping.

[0044] In some alternative implementations, the fixing component is a one-piece molded structure.

[0045] The above-mentioned technical solution has the following advantages or beneficial effects: designing the fixing component as a one-piece molded structure reduces the number of parts, avoids assembly processes, and lowers manufacturing costs. At the same time, the one-piece structure has higher overall strength and structural stability, avoids the risk of failure at the connection points, and improves product reliability.

[0046] The refrigerator provided in this application includes: a cabinet having an inner liner with an installation port; refrigeration pipes; and a fixing assembly including: a fixing member for fixing the refrigeration pipes; and a screw connector connected to the fixing member, wherein the screw connector is configured to rotate relative to the installation port to fix the refrigeration pipes to the inner liner.

[0047] By designing a fixing component, the fastener secures the refrigeration pipes, and the rotating operation of the screw connector can firmly lock the fastener with the refrigeration pipes onto the mounting port of the inner liner. Compared with adhesive installation, this simplifies the assembly process, improves production efficiency, and facilitates subsequent maintenance and disassembly, achieving fast and reliable installation of the refrigeration pipes.

[0074] Figure 1 This is a schematic diagram illustrating the assembly of the mounting components and the inner liner of the enclosure, provided for some embodiments. Figure 2 A cross-sectional view of the installation components and the inner liner provided for some embodiments.

[0075] like Figure 1 and Figure 2 As shown, currently, the refrigerator's refrigeration pipes (such as evaporator pipes) typically need to be fixed to the inner liner 111. Traditional fixing methods often use mounting components 200, which include mounting parts 210 and adhesive parts 220. One end of the mounting part 210 is fixed to the refrigeration pipes, and the other end is fixed to the inner liner 111 via the adhesive part 220. However, adhesive bonding has problems such as weak adhesion and susceptibility to aging and failure.

[0076] To overcome the shortcomings of the prior art, the refrigerator provided in this application, through the design of the fixing components, uses fixing parts to fix the refrigeration pipes, and the rotation operation of the screw connectors can firmly lock the fixing parts with the refrigeration pipes onto the installation port of the inner liner.

[0077] 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.

Figure 10 This is a cross-sectional view of the assembly of the fixing components and the inner liner of the refrigerator provided in an embodiment of this application.

[0079] like Figures 3 to 10 As shown, this application embodiment provides a refrigerator 100, including:

[0080] The enclosure 110 has an inner liner 111, and the inner liner 111 has an installation port 1111.

[0081] Refrigeration piping 130;

[0082] Fixing component 140 includes:

[0083] Fastener 141 is used to fix the refrigeration pipe 130;

[0084] A swivel connector 142 is connected to a fixing member 141 and is configured to rotate relative to the mounting port 1111 to secure the refrigeration pipe 130 to the inner liner 111.

[0085] With the above-described configuration, namely the refrigerator 100 of this application embodiment, the fixing component 140 is designed so that the fixing member 141 fixes the refrigeration pipe 130. The rotation operation of the screw connector 142 can firmly lock the fixing member 141, which fixes the refrigeration pipe 130, onto the mounting port 1111 of the inner liner 111. Compared with adhesive installation, this simplifies the assembly process, improves production efficiency, and facilitates subsequent maintenance and disassembly, thus achieving rapid and reliable installation of the refrigeration pipe 130.

[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 120. 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 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.

[0092] [Gate 120]

[0093] It should be noted that the door 120 can be connected to the cabinet 110 to open or close the refrigeration compartment.

[0094] A door 120 is disposed on the front surface of the enclosure 110 to enclose the refrigeration compartment. The door 120 is configured to open and close the refrigeration compartment, meaning it can open and close the front opening of the enclosure 110. Doors 120 can be correspondingly assigned to refrigeration compartments; that is, each refrigeration compartment can have one or more doors 120. The number of refrigeration compartments and doors 120, as well as the function of the refrigeration compartments, can be selected based on specific circumstances. One door 120 can be assigned to the same refrigeration compartment. Alternatively, two doors 120 can be assigned to the same refrigeration compartment.

[0095] In some possible implementations of this application, the door 120 can be rotatably connected to the housing 110 about the height direction Z of the housing 110. The door 120 can be pulled or pushed to rotate relative to the housing 110, thereby opening or closing the refrigeration compartment.

[0096] In some embodiments, the door 120 is a rotating door structure. The door 120 is rotatably disposed on the front side of the housing 110, and in this case, the door 120 can be used as a general door structure, such as a refrigerator door, a variable temperature door, etc.

[0097] Specifically, the door 120 and the cabinet 110 can be connected by a hinge so that the door 120 of the refrigerator 100 can rotate around the axis of the hinge, thereby opening and closing the door 120 and opening and closing the corresponding refrigeration compartment.

[0098] In some embodiments, the door 120 can also be a sliding door structure. The door 120 is slidably disposed on the front side of the cabinet 110, and in this case, the door 120 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 120 is connected to the guide rails on both sides, thereby realizing the sliding function of the door 120 and realizing the opening and closing of the refrigeration compartment by extending and retracting the guide rails.

[0099] [Refrigeration Components]

[0100] 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.

[0101] 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.

[0102] 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.

[0103] It should be noted that the refrigeration assembly also includes a refrigeration pipe 130, which is used to transport refrigerant.

[0104] [Fixed Component 140]

[0105] It should be noted that the refrigerator 100 also includes a fixing component 140, which is used to fix the refrigeration pipe 130 to the inner liner 111 after fixing the refrigeration pipe 130.

[0106] The fixing component 140 includes a fixed member 141 and a screw connector 142 connected together. The fixed member 141 is used to fix the refrigeration pipe 130, and the screw connector 142 is used to fix it to the inner liner 111, so that the refrigeration pipe 130 is fixed on the inner liner 111.

[0107] It should be noted that when the screw connector 142 is rotated into place, it can form a stable locking state, which can effectively resist the vibration generated during the operation of the refrigerator 100 and prevent the refrigeration pipe 130 from loosening or falling off due to long-term vibration, thereby improving the long-term reliability and safety of the product.

[0108] Furthermore, the entire fixing assembly 140 has a simple structure, making it easy to manufacture and control quality. This simple structure can be flexibly applied to different positions within the inner liner of the refrigerator 100, resulting in high design versatility.

[0109] like Figure 6 As shown, in some optional embodiments, there are at least two mounting ports 1111, and the at least two mounting ports 1111 are spaced apart along the width direction of the housing 110.

[0110] There are at least two fixing components 140, and the at least two fixing components 140 are spaced apart along the width direction of the housing 110.

[0111] The above technical solution has the following advantages or beneficial effects: By arranging multiple mounting ports 1111 and fixing components 140 at intervals along the width direction of the housing 110, multi-point and uniform support and fixation of the refrigeration pipes 130 are achieved. This layout can effectively prevent sagging, vibration or deformation caused by excessive pipe length, improve fixing reliability, ensure the long-term stability of the refrigeration system, and at the same time make the stress distribution more reasonable and avoid local stress concentration.

[0112] Furthermore, the spaced fixing points distribute the forces (such as gravity) on the pipes to multiple different locations within the inner liner 111. This design avoids excessive stress concentration at a single mounting point, preventing fatigue damage to the fixing component 140 itself due to excessive long-term stress, and reducing the risk of cracks or deformation in the inner liner 111 due to localized stress concentration, thereby improving the structural durability and service life of the entire refrigerator 100 system.

[0113] like Figures 7 to 10 As shown, in some optional embodiments, the refrigeration piping 130 is in an installed state;

[0114] When the refrigeration pipe 130 is in the installation state, the screw connector 142 abuts against the outer wall of the inner liner 111, and the fixing member 141 extends into the installation port 1111 and is located inside the inner liner 111.

[0115] The above technical solution has the following advantages or beneficial effects: the screw connector 142 abuts against the outer wall of the inner liner 111, and the fixing member 141 extends into the inner liner 111, which can ensure that the fixing component 140 is stably anchored on the wall of the box 110 and is not easy to loosen.

[0116] Furthermore, the swivel joint 142 provides a supporting surface on the outside, while the fastener 141 acts as a hook or limiter on the inside. Through rotation, the side wall of the inner liner 111 is firmly "clamped" between the swivel joint 142 and the fastener 141. This mechanical interlocking structure far surpasses the effect of single-sided adhesive fastening.

[0117] In addition, the surface contact between the screw connector 142 and the outer wall, and the support of the fastener 141 on the inner side, distribute the pipeline load to a larger area, effectively avoiding the squeezing deformation, scratches or cracks caused by concentrated stress on the inner liner material (usually plastic), and protecting the integrity of the box 110 structure.

[0118] Figure 11 This is a first-view structural schematic diagram of the fixing component in a refrigerator provided in an embodiment of this application. Figure 12 This is a second-view structural schematic diagram of the fixing component in a refrigerator provided in an embodiment of this application. Figure 13 This is a third-view structural schematic diagram of the fixing component in a refrigerator provided in an embodiment of this application. Figure 14 This is a structural schematic diagram of the fixing component in a refrigerator from a fourth perspective, provided in an embodiment of this application.

[0119] like Figure 9 and with 11 to Figure 14 As shown, in some alternative embodiments, the screw-on member 142 has a mounting surface 1421 that abuts against the outer wall of the inner liner 111.

[0120] The fastener 141 is connected to the mounting surface 1421 and extends in a direction away from the swivel connector 142.

[0121] The above technical solution has the following advantages or beneficial effects: The mounting surface 1421 abuts against the outer wall of the housing 110, providing a stable force-bearing foundation for the screw connection. The fastener 141 extends from the mounting surface 1421, making the overall structure compact and the force transmission path clear. This design optimizes the mechanical properties of the structure, ensuring uniform force distribution during rotation and enhancing the stability and strength of the fixation.

[0122] Furthermore, when the fastener 141 is subjected to tension or vibration from the refrigeration pipe 130 inside the inner liner 111, this force is transmitted through the fastener 141 to the screw connector 142 and ultimately borne by the mounting surface 1421. This allows the entire fastening assembly 140 to effectively resist forces that could loosen the pipe.

[0123] It should be noted that the large area of ​​the mounting surface 1421 in close contact with the outer wall of the enclosure 110 effectively forms a barrier against the mounting opening 1111. This prevents external dust from easily entering the insulation layer of the enclosure 110 through the mounting opening 1111, avoiding potential degradation of insulation performance or structural corrosion caused by internal condensation or dust accumulation, and improving the long-term reliability of the product.

[0124] In some embodiments, the screw-on member 142 is a plate-shaped structure having a flat mounting surface 1421. The fastener 141 extends vertically from the central region of the mounting surface 1421. The mounting surface 1421 is larger than the mounting opening 1111 to ensure that the screw-on member 142 can abut against the outer wall of the inner liner 111.

[0125] In some embodiments, the screw connector 142 is an arc-shaped cap, which can be deformed to achieve an elastic clamping effect.

[0126] Continue to refer to Figure 9 and with 11 to Figure 14 In some alternative embodiments, the inner liner 111 has an abutment portion 1112 that extends toward the mounting opening 1111.

[0127] In some alternative embodiments, the fixing component 140 further includes a limiting member 143 disposed on the outer periphery of the fixing member 141. The limiting member 143 has a limiting groove 1431, which has a movement trajectory for the abutment portion 1112 to move from the first end of the limiting member 143 to the second end of the limiting member 143, so that the limiting member 143 is screwed onto the inner liner 111 of the box.

[0128] The above technical solution has the following advantages or beneficial effects: the matching design of the limiting groove 1431 and the abutment part 1112 constitutes a highly efficient and quick snap-fit ​​connection. During assembly, simply place the abutment part 1112 into one end of the limiting groove 1431, and then rotate the fixing component 140. The abutment part 1112 will then slide along the track to the other end of the limiting groove 1431 and lock in place, simplifying the operation and further improving assembly efficiency.

[0129] Furthermore, the limiting groove 1431 provides a clear movement trajectory for the abutment part 1112. During assembly, the maintenance personnel need to align the abutment part 1112 with the first end (entrance) of the limiting groove 1431, and then rotate the fixing component 140, and the abutment part 1112 will slide along the preset trajectory to the second end. This greatly simplifies the operation, reduces the skill requirements of the workers, and significantly improves assembly efficiency and consistency.

[0130] In some embodiments, the trajectory of the limiting groove 1431 is typically designed not as a simple circular arc, but may include a spiraling upward or converging curve. As the abutment portion 1112 moves from the first end to the second end, this trajectory forces the fixing assembly 140 to rotate while simultaneously generating an axial displacement toward the outer wall of the inner liner 111. This displacement causes the mounting surface 1421 of the screw connector 142 to press tightly against the outer wall of the housing 110, thereby generating a strong clamping force.

[0131] In some embodiments, the mounting opening 1111 of the inner liner 111 has an inwardly protruding abutment portion 1112 formed at its edge. A limiting groove 1431 is formed on the limiting member 143, the limiting groove 1431 including an inlet section and a locking section. The groove wall of the limiting groove 1431 forms a limiting surface 1432.

[0132] In some alternative embodiments, the limiting member 143 also has a limiting surface 1432. When the refrigeration pipe 130 is in the installation state, along the depth direction of the housing 110, the mounting surface 1421 and the limiting surface 1432 are located on opposite sides of the inner liner 111.

[0133] Among them, the limiting surface 1432 is the groove wall of the limiting groove 1431.

[0134] The above technical solution has the following advantages or beneficial effects: It clarifies that in the locked state, the outer wall of the inner liner 111 is tightly clamped between the mounting surface 1421 of the screw connector 142 and the limiting surface 1432 of the limiting member 143. This effectively prevents the fixing assembly 140 from shaking or loosening in any direction, significantly enhancing the mechanical strength and stability of the fixation.

[0135] Furthermore, the bidirectional clamping structure effectively suppresses minor wobbling of the fixing component 140 and the refrigeration pipe 130 in the depth direction of the cabinet 110. Under the vibration and impact generated during the start-up and shutdown of the refrigerator 100 compressor or during transportation, the force generated by the pipe will be limited within the narrow space formed by the mounting surface 1421 and the limiting surface 1432, preventing the formation of a large displacement that would cause loosening.

[0136] In some alternative embodiments, the limiting member 143 further has a limiting portion 1433 located at the second end of the limiting member 143, and the limiting portion 1433 extends along the direction facing the mounting surface 1421.

[0137] The limiting part 1433 is configured to fix the abutting part 1112 to the second end of the limiting member 143 when the abutting part 1112 moves to the second end of the limiting member 143.

[0138] The above technical solution has the following advantages or beneficial effects: the limiting part 1433 acts as a stop when the abutting part 1112 moves to the end of the limiting groove 1431. The limiting part 1433 extends from the second end toward the mounting surface 1421, forming a physical barrier (similar to a protrusion). When the abutting part 1112 slides into the second end of the limiting groove 1431 during rotation, it can prevent the abutting part 1112 from continuing to rotate.

[0139] Furthermore, during installation, when the contact part 1112 slides to its end, the maintenance personnel will feel a noticeable sudden change in resistance. This allows the maintenance personnel to confirm that the installation is complete and locked, avoiding safety hazards caused by incomplete installation (not fully tightened), and greatly improving the reliability of the assembly quality.

[0140] In some embodiments, the limiting portion 1433 is a protrusion.

[0141] In some alternative embodiments, the fixing assembly 140 further includes a stop 144 disposed on the mounting surface 1421, and the stop 144 protrudes toward the first end of the limiting member 143 along the depth direction of the housing 110. The stop 144 is configured to prevent the abutment portion 1112 from moving along the second direction when the abutment portion 1112 moves along the first direction to the second end of the limiting member 143.

[0142] Among them, the first direction and the second direction are two opposite directions.

[0143] The above technical solution has the following advantages or beneficial effects: the limiting part 1433 is located at the second end of the limiting groove 1431 to prevent the abutting part 1112 from coming out. The blocking member 144 is located at the first end of the limiting groove 1431 to prevent the abutting part 1112 from retracting, thereby fixing the abutting part 1112 in the limiting groove 1431.

[0144] In some embodiments, the stop member 144 is a stop block.

[0145] In some embodiments, there is a gap between the stop member 144 and the limiting member 143 to facilitate the abutment portion 1112 entering the limiting groove 1431.

[0146] In some alternative embodiments, the fastener 141 has a slot 1411 for receiving the cooling pipe 130.

[0147] The above technical solution has the following advantages or beneficial effects: the slot 1411 provides a dedicated space for accommodating and positioning the refrigeration pipe 130. This not only more reliably holds or locks the pipe in place, preventing it from slipping out of the fastener 141, but also avoids hard friction or squeezing between the pipe and the fastener 141, thus protecting the pipe.

[0148] In some embodiments, the slot 1411 is typically designed to be interference-fitted or tightly fitted with the outer diameter of the refrigeration pipe 130. When the refrigeration pipe 130 is inserted, the groove wall of the slot 1411 wraps around and constrains the pipe from multiple directions, providing uniform holding force. This effectively prevents the refrigeration pipe 130 from laterally dislodging from the fastener 141 or from rotating and shifting under vibration, ensuring the reliability of the fixation.

[0149] In some alternative implementations, the fixing component 140 is a one-piece molded structure.

[0150] The above technical solution has the following advantages or beneficial effects: designing the fixing component 140 as a one-piece molded structural part reduces the number of parts, avoids assembly processes, and lowers manufacturing costs. At the same time, the one-piece structure has higher overall strength and structural stability, avoids the risk of failure at the connection points, and improves product reliability.

[0151] It should be noted that the installation process of the fixing component 140 is as follows: (e.g.) Figure 7 As shown, the fixing component 140 is now placed into the mounting port 1111. At this time, the fixing component 141 extends into the inner liner 111 and locks the refrigeration pipe 130. Then, the screw connector 142 is rotated 90° counterclockwise around the central axis to complete the locking with the inner liner 111.

[0152] Specifically, when the screw connector 142 rotates counterclockwise around the central axis, the abutting part 1112 of the inner liner 111 moves in the limiting groove 1431, from the first end of the limiting groove 1431 to the second end of the limiting groove 1431. It is restricted by the limiting part 1433 to prevent further forward movement, and blocked by the stop 144 to prevent further backward movement. Thus, the abutting part 1112 can be locked in the limiting groove 1431, which completes the locking with the inner liner 111.

[0153] The sidewall of the inner liner 111 is tightly clamped between the mounting surface 1421 (outer side) of the screw connector 142 and the limiting surface 1432 (inner side) of the limiting member 143. This completes the quick and secure installation of the refrigeration piping 130. For disassembly, simply rotate the fixing assembly 140 in the reverse direction, causing the abutment part 1112 to retract along the limiting groove 1431 to the inlet end, and the entire fixing assembly 140 along with the refrigeration piping 130 can be removed.

[0154] The refrigerator provided in this application includes a cabinet with an inner liner having an installation port; refrigeration pipes; and a fixing assembly including: a fixing member for fixing the refrigeration pipes; and a screw connector connected to the fixing member, wherein the screw connector is configured to rotate relative to the installation port to fix the refrigeration pipes to the inner liner.

[0155] By designing a fixing component, the fastener secures the refrigeration pipes, and the rotating operation of the screw connector can firmly lock the fastener with the refrigeration pipes onto the mounting port of the inner liner. Compared with adhesive installation, this simplifies the assembly process, improves production efficiency, and facilitates subsequent maintenance and disassembly, achieving fast and reliable installation of the refrigeration pipes.
