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 technological advancements, meeting users' needs for food preservation, storage, and other aspects.

[0003] In conceiving and implementing this application, the applicant discovered at least the following problems: Currently, in refrigerator manufacturing, the sealing of the refrigeration pipes is a crucial aspect in ensuring the quality of the refrigerator body foaming process. The refrigerator body typically forms an insulation layer through a foaming process, while the refrigeration pipes (such as evaporator and condenser pipes) need to pass through the body wall to enter the internal space. Two refrigeration pipes enter the body as a set, and a rubber stopper simultaneously covers both pipes. A preliminary seal is achieved between the rubber stopper and the pipes through a gap fit; however, gaps exist between the rubber stopper and the two pipes, allowing the foaming material to easily leak out, leading to seal 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 that eliminates material leakage caused by gaps between two adjacent refrigeration pipes.

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

[0007] The box body has an inner liner;

[0008] At least two cooling pipes;

[0009] A sealing assembly, connected to the inner liner of the enclosure, includes:

[0010] The first sealing element is attached to the side wall of the inner liner of the box:

[0011] At least two sealing tubes are connected to the first seal, each sealing tube corresponding to a refrigeration pipe, and the sealing tubes are configured to wrap the refrigeration pipe so that the refrigeration pipe is connected to the inner liner of the box.

[0012] The beneficial effects of this application are: through the design of the sealing component, the first sealing element can achieve the first seal with the inner liner of the box, and the independent sealing tube design allows for a separate sealing tube for each refrigeration pipe, replacing the existing technology where multiple pipes share a single sealing structure (such as a rubber plug), fundamentally eliminating leakage caused by the gap between two adjacent refrigeration pipes.

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

[0014] In some alternative implementations, the inner liner of the box has:

[0015] The assembly part, the sealing component is installed in the assembly part, and the assembly part has an assembly surface;

[0016] The first sealing element is a plate-shaped structure and has the following characteristics:

[0017] The sealing surface is attached to the assembly surface, and the shape of the sealing surface matches the shape of the assembly surface.

[0018] The above technical solution has the following advantages or beneficial effects: the matching shape plays a guiding and positioning role, and the sealing component can be placed in the correct position quickly and accurately during the assembly process, which reduces the assembly difficulty and reduces sealing failure caused by misalignment.

[0019] In some alternative embodiments, the assembly part is provided with a first mounting hole that extends through opposite sides of the assembly part;

[0020] The first sealing element is provided with a second mounting hole, which is connected to the first mounting hole, and the sealing tube is matched with the second mounting hole so that the refrigeration pipe is connected to the opposite sides of the inner liner of the box.

[0021] The above technical solution has the following advantages or beneficial effects: This design provides full support and insulation for the refrigeration pipe section passing through the inner liner of the box, avoids leakage problems, and prevents pipe wear caused by vibration and friction.

[0022] In some alternative implementations, the sealing assembly further includes:

[0023] The second seal wraps around the outer periphery of the refrigeration pipe and is located inside the sealing pipe.

[0024] The above technical solution has the following advantages or beneficial effects: the second seal can fill the unavoidable manufacturing tolerances and gaps between the outer wall of the refrigeration pipe and the inner wall of the sealing pipe, achieving a tighter fit.

[0025] In some alternative implementations, the second seal is a heat-shrink sleeve.

[0026] The above technical solution has the following advantages or beneficial effects: heat shrink tubing is used, which can tightly wrap the pipeline after heating, forming a seal.

[0027] In some alternative embodiments, a limiting part is provided inside the sealing tube, the limiting part protruding towards the center of the sealing tube, and the second sealing member abuts against the limiting part.

[0028] The above technical solution has the following advantages or beneficial effects: the limiting part ensures that the second sealing element is installed in the pre-designed position inside the sealing tube, preventing it from shifting during assembly or use, and ensuring that the sealing effect is always in the best state.

[0029] In some alternative implementations, the limiting part is a limiting boss.

[0030] The above technical solution has the following advantages or beneficial effects: such a setting can satisfy the limiting function of assembling the second sealing element, while also being easy to process and having a low manufacturing cost.

[0031] In some alternative embodiments, the sealing tube includes:

[0032] The guide pipe section is located at the opening of the sealing pipe;

[0033] The sealing pipe section, along the extension direction of the sealing pipe, is connected to the guide pipe section and is located in the middle of the sealing pipe, and the second sealing element is located inside the sealing pipe section;

[0034] The radial dimension of the guide pipe section is larger than that of the sealing pipe section.

[0035] The above technical solution has the following advantages or beneficial effects: the inner wall of the sealing tube is provided with a guide tube section and a sealing tube section. The guide tube section has a large diameter, which facilitates the insertion of the refrigeration pipe and guides the refrigeration pipe to ensure accurate positioning. The sealing tube section has a small diameter, which is intended to seal and fix the refrigeration pipe. After the heat shrink sleeve wraps the refrigeration pipe, it cooperates with the sealing tube section to form a tight contact, replacing the traditional rubber plug.

[0036] In some alternative implementations, the refrigerator includes:

[0037] Adhesive parts are attached between the sealing surface and the assembly surface.

[0038] The above technical solution has the following advantages or beneficial effects: it ensures the connection stability between the first sealing element and the inner liner of the box, uses adhesive parts, has good sealing performance, and has a simple process and controllable cost.

[0039] It should be noted that during installation, firstly, the sealing component is initially attached to the assembly part of the inner liner using adhesive, ensuring that the second mounting hole is aligned with the first mounting hole. Then, a heat-shrink sleeve is fitted as a second seal at the pre-set pipe insertion position for each refrigeration pipe. Next, the refrigeration pipe with the heat-shrink sleeve is inserted through the guide section of the sealing pipe.

[0040] In some alternative implementations, the first seal and the sealing tube are integrally formed structural components.

[0041] The above technical solution has the following advantages or beneficial effects: by setting the first sealing element and the sealing tube as an integral molding, not only can the connection strength between the first sealing element and the sealing tube be improved, but also the seamless connection between the first sealing element and the sealing tube can be achieved, thereby reducing the risk of cracking at the connection position of the first sealing element and the sealing tube.

[0042] The refrigerator provided in this application includes: a cabinet having an inner liner; at least two refrigeration pipes; and a sealing assembly connected to the inner liner. The sealing assembly includes: a first sealing element attached to the side wall of the inner liner; and at least two sealing tubes connected to the first sealing element, each sealing tube corresponding to one refrigeration pipe. The sealing tubes are configured to wrap around the refrigeration pipes so that the refrigeration pipes are connected to the inner liner.

[0043] Through the design of the sealing components, the first seal can achieve the first seal with the inner liner of the box, and the independent sealing tube design allows for a separate sealing tube for each refrigeration pipe, replacing the existing technology where multiple pipes share a single sealing structure (such as a rubber plug), fundamentally eliminating leakage caused by gaps between two adjacent refrigeration pipes.

[0065] Currently, in refrigerator manufacturing, the sealing of the refrigeration piping is a crucial aspect of ensuring the quality of the refrigerator body's foaming process. The refrigerator body typically forms an insulation layer through a foaming process, while the refrigeration piping (such as evaporator and condenser piping) needs to penetrate the body wall into the internal space. During the foaming process, the foaming material must be sealed to prevent leakage from the gaps between the piping and the body; otherwise, it can lead to uneven foaming, reduced insulation performance, and even pipe corrosion. In existing technologies, multiple refrigeration piping lines are usually sealed using a shared sealing structure (such as rubber plugs).

[0066] Specifically, two refrigeration pipes enter the housing as a set, and a rubber plug simultaneously covers both pipes. The rubber plug and the pipes achieve a preliminary seal through a gap fit. However, there is a gap between the rubber plug and the two pipes, and the foaming material can easily overflow from the gap, leading to seal failure.

[0067] In order to overcome the defects in the prior art, the refrigerator provided in this application, through the design of the sealing component, can achieve the first sealing with the inner liner of the refrigerator, and the independent sealing tube design, which designs a sealing tube for each refrigeration pipe separately, replaces the solution in the prior art where multiple pipes share a single sealing structure (such as a rubber plug), fundamentally eliminating the leakage caused by the gap between two adjacent refrigeration pipes.

[0068] 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.

[0069] Figure 1 This is a schematic diagram of the structure of a refrigerator provided in an embodiment of this application. Figure 2 This is a first-view assembly diagram of a portion of the inner liner and sealing assembly in a refrigerator, provided as an embodiment of this application. Figure 3 This is a second-view exploded view of a portion of the inner liner and sealing assembly of a refrigerator, provided in an embodiment of this application. Figure 4 This is a cross-sectional view of the assembly of a portion of the inner liner and sealing components in a refrigerator provided in an embodiment of this application.

[0070] like Figures 1 to 4 As shown, this application embodiment provides a refrigerator 100, including:

[0071] The box body 110 has an inner liner 111;

[0072] At least two refrigeration pipes of 130;

[0073] Sealing assembly 140 is connected to the inner liner 111 of the box. Sealing assembly 140 includes:

[0074] The first sealing element 141 is attached to the side wall of the inner liner 111 of the box:

[0075] At least two sealing tubes 143 are connected to the first seal 141, each sealing tube 143 corresponds to a refrigeration pipe 130, and the sealing tubes 143 are configured to wrap the refrigeration pipe 130 so that the refrigeration pipe 130 is connected to the inner liner 111.

[0076] With the above-mentioned settings, namely, the refrigerator 100 of this application embodiment, through the design of the sealing component 140, the first sealing member 141 can achieve the first seal with the inner liner 111, and the independent sealing tube 143 design, the sealing tube 143 is designed separately for each refrigeration pipe 130, replacing the solution of multiple pipes sharing a single sealing structure (such as a rubber plug) in the prior art, fundamentally eliminating the leakage caused by the gap of the refrigeration pipe 130.

[0077] It should be noted that the following provides a detailed explanation of each structure.

[0078] [Box 110]

[0079] 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.

[0080] 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.

[0081] 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.

[0082] 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.

[0083] [Gate 120]

[0084] It should be noted that the door 120 can be connected to the cabinet 110 to open or close the refrigeration compartment.

[0085] 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.

[0086] 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.

[0087] 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.

[0088] 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.

[0089] 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.

[0090] [Refrigeration Components]

[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 the refrigeration assembly also includes a refrigeration pipe 130, which is used to transport refrigerant.

[0095] [Sealing assembly 140]

[0096] Figure 5 This is a third-view assembly diagram of a portion of the inner liner and sealing assembly in a refrigerator, provided in an embodiment of this application. Figure 6 This is a fourth-view exploded view of a portion of the inner liner and sealing assembly of a refrigerator provided in an embodiment of this application. Figure 7 This is a fifth-view exploded view of part of the inner liner and sealing assembly of a refrigerator provided in an embodiment of this application.

[0097] like Figures 2 to 7 As shown, it should be noted that the refrigerator 100 also includes a sealing assembly 140, which is used to fix the refrigeration pipe 130 to the inner liner 111.

[0098] In some embodiments, the sealing assembly 140 includes a first seal 141, which serves as the base for the entire sealing assembly 140.

[0099] The first sealing element 141 can be a plate-like or sheet-like component, directly attached to the side wall of the inner liner 111. This surface contact design is the basis for its efficient sealing. It achieves a large-area static seal with the inner liner 111, forming the first sealing barrier.

[0100] In addition, the first sealing element 141 serves as a base, integrating multiple sealing tubes 143 into one unit, which enhances the rigidity and stability of the overall structure and avoids the problem of individual sealing tubes 143 being prone to loosening.

[0101] In some embodiments, the sealing assembly 140 further includes at least two sealing tubes 143 connected to the first seal 141. Each sealing tube 143 independently wraps around a cooling pipe 130, isolating the pipe from the external environment (particularly the subsequently injected foam layer).

[0102] The structure of "sealing tube 143 wrapping refrigeration pipe 130" provides an independent and reliable sealing channel for each refrigeration pipe 130, effectively preventing problems such as foaming and leakage.

[0103] It should be noted that the first seal 141 achieves a seal with the inner liner 111, which is the first robust barrier. Each sealing tube 143 achieves a seal with the refrigeration pipe 130, which is the second specialized barrier.

[0104] In some alternative embodiments, the inner liner 111 has:

[0105] Assembly part 1111, sealing component 140 is mounted on assembly part 1111, assembly part 1111 has assembly surface;

[0106] The first sealing element 141 is a plate-shaped structure and has the following characteristics:

[0107] The sealing surface 1411 is attached to the assembly surface, and the shape of the sealing surface 1411 matches the shape of the assembly surface.

[0108] The above technical solution has the following advantages or beneficial effects: the matching shape plays a guiding and positioning role, and the sealing component 140 can be placed in the correct position quickly and accurately during the assembly process, which reduces the assembly difficulty and reduces the sealing failure caused by misalignment.

[0109] In addition, the contact area between the first seal 141 and the inner liner 111 is ensured, creating optimal conditions for the use of adhesives or gaskets, thereby greatly improving the sealing effect at the interface.

[0110] In some embodiments, the sealing assembly 140 is integrally injection molded from silicone rubber using a mold, and includes a plate-shaped first seal 141 and two sealing tubes 143 extending from the first seal 141.

[0111] In some embodiments, the back side of the first seal 141 is a flat sealing surface 1411, the shape of which perfectly matches the mounting surface of the assembly part 1111.

[0112] In another embodiment, the mounting portion 1111 of the inner liner 111 is an inwardly recessed groove-like structure with a curved mounting surface. Correspondingly, the sealing surface 1411 of the first seal 141 is also made into a matching curved surface to provide a larger contact area and a better fit.

[0113] In some embodiments, the materials of the first seal 141 and the sealing tube 143 may be selected from EPDM (ethylene propylene diene monomer rubber), which is more resistant to low temperatures.

[0114] In some alternative embodiments, the assembly part 1111 is provided with a first mounting hole 112, which penetrates through opposite sides of the assembly part 1111.

[0115] The first sealing element 141 is provided with a second mounting hole 1412, which is connected to the first mounting hole 112, and the sealing tube 143 is matched with the second mounting hole 1412 so that the refrigeration pipe 130 is connected to the opposite sides of the inner liner 111.

[0116] The above technical solution has the following advantages or beneficial effects: This arrangement provides full support and insulation for the refrigeration pipe 130 section passing through the inner liner 111, avoiding leakage problems and preventing pipe wear caused by vibration and friction.

[0117] Furthermore, this design protects applications where the refrigeration piping 130 needs to pass through the wall of the inner liner 111 (e.g., piping from the refrigerator compartment to the freezer compartment). This structure ensures an effective seal on both sides of the inner liner 111, which is impossible with a single-sided seal.

[0118] In some embodiments, the first seal 141 has two second mounting holes 1412, the positions of which correspond one-to-one with the first mounting holes 112.

[0119] Furthermore, the sealing tube 143 is explicitly designed to mate with the second mounting hole 1412. Here, "mate" can be understood as the sealing tube 143 being able to be inserted into the second mounting hole 1412, or its root being joined to the edge of the second mounting hole 1412 through a sealing lip, interference fit, or other means to ensure the sealing of the connection.

[0120] In some embodiments, the first mounting hole 112 and the second mounting hole 1412 are identical in shape and size, and the second mounting hole 1412 is matched with the size of the refrigeration pipe 130.

[0121] Figure 8 This is a schematic diagram of the refrigeration piping structure in a refrigerator provided in an embodiment of this application. Figure 9 This is a first-view structural schematic diagram of the sealing assembly in a refrigerator provided in an embodiment of this application. Figure 10 This is a second-view structural schematic diagram of the sealing assembly in a refrigerator provided in an embodiment of this application. Figure 11 This is a third-view structural schematic diagram of the sealing assembly in a refrigerator provided in an embodiment of this application.

[0122] like Figures 2 to 11 As shown, in some optional embodiments, the sealing assembly 140 further includes:

[0123] The second seal 142 wraps around the outer periphery of the refrigeration pipe 130 and is located inside the sealing pipe 143.

[0124] The above technical solution has the following advantages or beneficial effects: the second seal 142 can fill the unavoidable manufacturing tolerances and gaps between the outer wall of the refrigeration pipe 130 and the inner wall of the sealing pipe 143, so as to achieve a tighter fit.

[0125] Furthermore, the first seal 141 is formed by fitting the mating surface of the inner liner 111. This is the first barrier, preventing the external environment (especially the foaming material) from intruding over a large area. The second seal 142 is formed by direct and tight contact with the outer wall of the refrigeration pipe 130, and the outer side of the second seal 142 is formed by tight contact with the inner wall of the sealing pipe 143, firmly locking the second seal 142 inside the sealing pipe 143, preventing its movement, and ensuring the effective transmission of sealing pressure.

[0126] In some embodiments, the second seal 142 serves as a flexible, compressible intermediate medium capable of filling unevenness and tolerance gaps. It can adapt to both the outer wall of the pipeline and the inner wall of the sealing tube 143 through its own deformation, thus avoiding the risk of foam material leakage.

[0127] Flexible seals can better absorb minor vibrations in pipelines and dimensional changes caused by temperature variations, avoiding seal fatigue or failure due to stress concentration and improving the sealing stability of the product during long-term use.

[0128] In some embodiments, the second seal 142 may be made of a special material to meet specific needs. A viscoelastic sealant or gel can be used to form an adhesive seal.

[0129] In some embodiments, the second seal 142 may be a sealing ring.

[0130] In some alternative embodiments, the second seal 142 is a heat shrink sleeve.

[0131] The above technical solution has the following advantages or beneficial effects: heat shrink tubing is used, which can tightly wrap the pipeline after heating, forming a seal.

[0132] Furthermore, the heat-shrink sleeve, serving as the second sealing element 142, shrinks under heat and can fit tightly against the irregularly shaped outer wall of the pipe, achieving a seal without any dead angles. Installation is also simple, requiring only heating.

[0133] Furthermore, heat-shrinkable materials (such as polyolefins) typically have good low-temperature resistance, aging resistance, and insulation properties, making them ideal for the long-term use environment of refrigerator 100.

[0134] In some embodiments, the second seal 142 may be a pre-formed elastic rubber ring, in addition to a heat shrink sleeve, and is pressed between the refrigeration pipe 130 and the sealing pipe 143 by an interference fit.

[0135] In some alternative embodiments, a limiting part 1433 is provided inside the sealing tube 143, the limiting part 1433 protrudes toward the center of the sealing tube 143, and the second sealing member 142 abuts against the limiting part 1433.

[0136] The above technical solution has the following advantages or beneficial effects: the limiting part 1433 ensures that the second sealing element 142 is installed in the pre-designed position inside the sealing tube 143, preventing it from shifting during assembly or use, and ensuring that the sealing effect is always in the best state.

[0137] It should be noted that the limiting part 1433 is arranged radially along the sealing tube 143, that is, the limiting part 1433 is a structure that protrudes from the inner wall of the sealing tube 143 toward the central axis.

[0138] In some embodiments, the limiting portion 1433 may be an annular protrusion or a step.

[0139] For example, the limiting portion 1433 can be a continuous ring or a plurality of discontinuous protrusions, as long as it can provide a reliable contact surface for the second seal 142.

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

[0141] The above technical solution has the following advantages or beneficial effects: such a setting can satisfy the limiting function of assembling the second seal 142, while also being easy to process and having a low manufacturing cost.

[0142] It should be noted that the limiting protrusions are arranged around the outer circumference of the inner wall of the sealing tube 143. This arrangement ensures that the second seal 142 receives uniform support in the circumferential direction. Compared with intermittent protrusions, it ensures that the second seal 142 will not tilt or deviate in any way.

[0143] In some embodiments, the cross-section of the limiting part 1433 can be rectangular, triangular, or irregular, as long as it can limit and fix the second seal 142.

[0144] In some alternative embodiments, the sealing tube 143 includes:

[0145] Guide pipe section 1431 is located at the opening of sealing pipe 143;

[0146] The sealing pipe section 1432 is connected to the guide pipe section 1431 along the extension direction of the sealing pipe 143 and is located in the middle of the sealing pipe 143. The second sealing element 142 is located inside the sealing pipe section 1432.

[0147] The radial dimension of the guide pipe section 1431 is greater than the radial dimension of the sealing pipe section 1432.

[0148] The above technical solution has the following advantages or beneficial effects: the inner wall of the sealing tube 143 is provided with a guide tube section 1431 and a sealing tube section 1432. The guide tube section 1431 has a large diameter, which facilitates the insertion of the refrigeration pipe 130 and guides the refrigeration pipe 130 to ensure accurate positioning of the pipe. The sealing tube section 1432 has a small diameter, which is used to seal and fix the refrigeration pipe 130. After the heat shrink sleeve wraps the refrigeration pipe 130, it cooperates with the sealing tube section 1432 to form a tight contact, replacing the traditional rubber plug.

[0149] Furthermore, the guide tube section 1431 provides a "flared mouth" which serves to guide and correct deviations when the refrigeration pipe 130, which is wrapped with the second seal 142, is inserted. Even with slight alignment errors, it can be easily introduced, significantly reducing assembly difficulty and improving production efficiency.

[0150] The sealing section 1432 ensures a tight fit with the outer wall of the second seal 142, working together to achieve a final, reliable seal.

[0151] In some embodiments, the sealing tube 143 consists of two sections: the section near the opening is the guide section 1431, which has a larger inner diameter and forms a flared opening; the inner section is the sealing section 1432, which has a smaller inner diameter.

[0152] In some embodiments, the guide tube section 1431 and the sealing tube section 1432 are integrally formed structures. The guide tube section 1431 and the sealing tube section 1432 are not separate structures connected by assembly, but rather a complete, seamless single part manufactured by the same mold and a one-time injection molding process.

[0153] In some alternative embodiments, the refrigerator 100 includes:

[0154] The adhesive component is attached between the sealing surface 1411 and the assembly surface.

[0155] The above technical solution has the following advantages or beneficial effects: it ensures the connection stability between the first sealing element 141 and the inner liner 111, uses adhesive parts, has good sealing performance, and has a simple process and controllable cost.

[0156] In addition, compared with mechanical buckles and screw fixing, adhesive fixing does not require the design of complex slots, studs and other structures on the inner liner 111 and the first sealing element 141.

[0157] In some embodiments, the adhesive may be in the form of a sheet or a film.

[0158] For example, the adhesive can be double-sided tape, self-adhesive label, pre-coated pressure-sensitive adhesive layer, or liquid sealant / silicone (which forms an adhesive layer after curing), etc.

[0159] It should be noted that during installation, the sealing component 140 is first initially attached to the assembly part 1111 of the inner liner 111 using adhesive, ensuring that the second mounting hole 1412 is aligned with the first mounting hole 112. Then, a heat shrink sleeve is fitted as a second seal 142 at the preset pipe insertion position of each refrigeration pipe 130. Next, the refrigeration pipe 130 with the heat shrink sleeve is inserted into the guide section 1431 of the sealing pipe 143.

[0160] The flared design of the guide tube section 1431 guides the tubing and heat shrink sleeve smoothly into place until the front end of the heat shrink sleeve abuts against the limiting part 1433. At this point, a heat gun is used to heat the heat shrink sleeve, causing it to shrink and tightly wrap around the outer wall of the refrigeration tubing 130, and fit tightly against the inner wall of the sealing tube section 1432. Finally, the refrigeration tubing 130 passes through the inner liner 111, completing the installation.

[0161] In this structure, the first sealing element 141 and the inner liner 111 form a first surface seal through an adhesive, blocking the foam material. The shrunken heat shrink sleeve forms a second tight seal with the inner wall of the refrigeration pipe 130 and the sealing pipe 143, further preventing media penetration. The limiting part 1433 ensures that each heat shrink sleeve can be precisely positioned at the same depth, guaranteeing consistent sealing performance.

[0162] In some alternative embodiments, the first seal 141 and the sealing tube 143 are integrally formed structural components.

[0163] The above technical solution has the following advantages or beneficial effects: by setting the first sealing element 141 and the sealing tube 143 as an integral molding, not only can the connection strength between the first sealing element 141 and the sealing tube 143 be improved, but also a seamless connection between the first sealing element 141 and the sealing tube 143 can be achieved, thereby reducing the risk of cracking at the connection position of the first sealing element 141 and the sealing tube 143.

[0164] The refrigerator provided in this application includes a cabinet with an inner liner; at least two refrigeration pipes; and a sealing assembly connected to the inner liner. The sealing assembly includes: a first sealing element attached to the side wall of the inner liner; and at least two sealing tubes connected to the first sealing element, each sealing tube corresponding to one refrigeration pipe. The sealing tubes are configured to wrap around the refrigeration pipes so that the refrigeration pipes are connected to the inner liner.

[0165] Through the design of the sealing components, the first seal can achieve the first seal with the inner liner of the box, and the independent sealing tube design allows for a separate sealing tube for each refrigeration pipe, replacing the existing technology where multiple pipes share a single sealing structure (such as a rubber plug), fundamentally eliminating leakage caused by gaps between two adjacent refrigeration pipes.
