[0033] The present application embodiment provides a refrigerator 100, see Figures 1 to 3 , including a box body 2 and an inner liner assembly 1 in any embodiment of the present application, the box body 2 has a second accommodating cavity 21, the inner liner 11 is accommodated in the second accommodating cavity 21, the mouth frame 12 is connected to the box body 2, and the mouth frame 12 closes the gap between the box body 2 and the inner liner 11.

[0034] The box body 2 is the outer shell of the refrigerator 100, which is usually made of materials such as metal or plastic, has a certain strength and sealing performance, and is used to accommodate and protect various internal components.

[0035] The second accommodating cavity 21 is a space in the box body 2 for placing components such as the inner liner assembly 1 . The specific structure is determined according to the structure of the inner liner assembly 1 and is not limited here.

[0036] The inner liner assembly 1 consists of an inner liner 11 and a mouth frame 12, which is used to form a specific storage space in the refrigerator 100. The inner liner 11 in the inner liner assembly 1 is accommodated in the second accommodating cavity 21 of the box body 2. The mouth frame 12 is connected to the box body 2 and can close the gap between the box body 2 and the inner liner 11.

[0037] The specific form of connection between the mouth frame 12 and the box body 2 is not limited here. For example, it can be connected by fasteners, or connected through a snap buckle 1131 structure, or it can be connected magnetically, or it can be connected by sealant, etc.

[0038] By designing the inner tank assembly 1 to be connected to the box body 2, the space inside the refrigerator 100 can be reasonably utilized, while reducing the possibility of cold air leakage and external impurities entering.

[0039] In some embodiments, see Figures 1 to 3 The gap between the inner liner 11 and the box body 2 is filled with a foaming agent.

[0040] A foaming agent is a material that undergoes a chemical reaction under certain conditions to produce a foamy substance. It is commonly used for filling gaps, insulation, and other purposes. The gap between the inner liner 11 and the refrigerator body 2 of refrigerator 100 is filled with a foaming agent. Once filled into this gap, the foaming agent expands to form a foamy structure, thus filling the space between the inner liner 11 and the refrigerator body 2.

[0041] In some embodiments, a groove structure is provided between the mouth frame 12 and the box body 2. The liner assembly 1 is pre-installed at the designed position of the box body 2 through the groove structure and then filled with foaming agent, which is beneficial to improve the installation accuracy of the liner assembly 1.

[0042] In some embodiments, the foaming agent is used in combination with other thermal insulation materials, sound absorbing materials, etc. to further improve the performance of the refrigerator 100.

[0043] By filling the gap between the inner liner 11 and the housing 2 with a foaming agent, the foamed structure formed by the foaming agent has excellent thermal insulation properties, which can reduce heat exchange between the interior of the refrigerator 100 and the external environment, reduce energy consumption, and improve the cooling efficiency of the refrigerator 100. Filling with the foaming agent can make the connection between the inner liner 11 and the housing 2 tighter, enhance the overall structural stability of the refrigerator 100, and reduce vibration and noise.

[0044] The present application embodiment provides an inner liner assembly 1, see Figures 1 to 3 , comprising an inner liner 11 and a mouth frame 12. The inner liner 11 has a first accommodating cavity 111 and an opening 112, the first accommodating cavity 111 communicating with the opening 112, and the inner liner 11 is provided with a first clamping portion 113. The mouth frame 12 has an opening 121, which is disposed at the opening 112 of the inner liner 11, and the opening 121 communicates with the first accommodating cavity 111. The mouth frame 12 is provided with a second clamping portion 122, which is engaged with the first clamping portion 113 via the second clamping portion 122.

[0045] The inner liner 11 is a container body with a certain shape and capacity, used to hold items or substances. In the embodiment of the present application, the inner liner 11 has a first receiving cavity 111 and an opening 112. The first receiving cavity 111 is the main carrying and storage space, and items are placed into the first receiving cavity 111 through the opening 112.

[0046] The specific structure of the inner liner 11 is not limited here. The inner liner 11 can be designed into various shapes, such as cylindrical, square, oval, etc., to adapt to different usage requirements and space limitations.

[0047] The opening frame 12 is a frame structure installed at the opening 112 of the inner liner 11, and plays a certain fixing, decorative or auxiliary function.

[0048] The material of the mouth frame 12 is not limited here, and can be, for example, plastic, metal, wood, etc., to meet different strength, aesthetics and cost requirements.

[0049] The first accommodating cavity 111 is a space inside the inner container 11 for placing items, and is connected to the outside through the opening 112 to facilitate the placement and removal of items.

[0050] In some embodiments, different functional partitions are provided in the first accommodating cavity 111 . For example, the accommodating cavity is divided into different areas by partitions for storing different types of items.

[0051] The opening 112 is the opening 121 on the inner container 11 , so that the first accommodating cavity 111 has a channel for interaction with the external environment.

[0052] The first clamping portion 113 is a structural portion provided on the inner liner 11 for connecting with the mouth frame 12 , and is fixed to the second clamping portion 122 on the mouth frame 12 by clamping.

[0053] Similarly, the second clamping portion 122 is a structural portion provided on the mouth frame 12 for connecting with the inner liner 11 , and cooperates with the first clamping portion 113 of the inner liner 11 to achieve a fixed connection between the mouth frame 12 and the inner liner 11 .

[0054] The specific structure of the first clamping portion 113 and the second clamping portion 122 is not limited here. In some embodiments, the structure of the first clamping portion 113 and the second clamping portion 122 can be improved by adopting a more secure buckle 1131 design, adding an anti-slip structure, etc., to improve the stability and reliability of the clamping.

[0055] The present embodiment provides an inner liner assembly 1, wherein a first accommodating cavity 111 of the inner liner 11 is connected to an opening 112, a mouth frame 12 is disposed at the opening 112 of the inner liner 11, and an opening 121 is connected to the first accommodating cavity 111. This facilitates the storage and placement of items. By providing a first snap-fit portion 113 on the inner liner 11 and a second snap-fit portion 122 on the mouth frame 12 that can snap-fit with the first snap-fit portion 113, that is, the snap-fit between the inner liner 11 and the mouth frame 12, the connection between the inner liner 11 and the mouth frame 12 is made more secure and reliable, reducing the possibility of accidental separation of the mouth frame 12 from the inner liner 11 and improving the structural stability of the inner liner assembly 1. Furthermore, the corresponding relationship between the first snap-fit portion 113 and the second snap-fit portion 122 helps reduce the difficulty of positioning during the fitting process. The snap-fit form also simplifies the assembly operation of the inner liner 11 and the mouth frame 12, thereby improving production efficiency and reducing production costs.

[0056] In some embodiments, see Figures 1 to 3A mounting groove 123 is provided on the mouth frame 12 , and a side of the inner liner 11 with the opening 112 extends into the mounting groove 123 .

[0057] The mounting groove 123 is a groove provided on the mouth frame 12 for accommodating a specific structure. In the embodiment of the present application, the mounting groove 123 is used to accommodate the structure on the side of the inner container 11 where the opening 112 is formed.

[0058] The specific shape of the mounting groove 123 is not limited here. The mounting groove 123 can be designed in different shapes according to the shape and size of the inner liner 11, such as round, square, special shape, etc., to better adapt to the structure of the inner liner 11 and improve the tightness of the connection.

[0059] The depth of the mounting groove 123 controls the fit between the inner container 11 and the mouth frame 12. It is understood that a deeper mounting groove 123 provides stronger fixing force but may increase manufacturing difficulty; a shallower mounting groove 123 may facilitate installation and removal. The depth of the mounting groove 123 can be determined based on actual conditions and is not limited here.

[0060] In some embodiments, some auxiliary structures, such as anti-slip pads, sealing strips, etc., can be provided inside the mounting groove 123 to enhance the friction and sealing between the inner liner 11 and the opening frame 12 .

[0061] In some embodiments, the mounting groove 123 can be used in combination with other connection methods, such as snap connection, bolt connection, etc., to further improve the connection strength and stability between the inner liner 11 and the mouth frame 12.

[0062] By providing a mounting groove 123 on the opening frame 12, the side of the inner liner 11 with the opening 112 extends into the mounting groove 123 during assembly, thereby providing a tighter and more stable connection between the inner liner 11 and the opening frame 12. The mounting groove 123 forms a good fit with the inner liner 11, reducing gaps and thus reducing the possibility of external impurities and moisture entering the inner liner 11, thereby improving the sealing performance of the refrigerator 100. Furthermore, the mounting groove 123 provides a clear location and guidance for the installation of the inner liner 11, making the installation process simpler and faster, thereby improving production efficiency.

[0063] In some embodiments, see Figures 1 to 3 , the second clamping portion 122 is located in the installation groove 123 .

[0064] The second clamping portion 122 is a structural portion provided on the mouth frame 12 for cooperating with the first clamping portion 113 on the inner liner 11 to achieve a fixed connection between the mouth frame 12 and the inner liner 11 .

[0065] The specific location of the opening frame 12 is not limited here. For example, it can be located on the side wall of the installation groove 123 or on the bottom wall of the installation groove 123 .

[0066] The shape of the second engaging portion 122 is not limited herein; its structural design should be coordinated with the structural design of the first engaging portion 113. Furthermore, the second engaging portion 122 should be designed based on the shape and size of the mounting slot 123 to better accommodate the structure of the mounting slot 123 and enhance the stability of the engagement. For example, the second engaging portion 122 may be in a hook-like, bump-like, or other shape.

[0067] In some embodiments, some auxiliary structures, such as positioning protrusions, guide grooves, etc., are provided in the installation groove 123 to cooperate with the second clamping portion 122 to further improve the accuracy and stability of the clamping.

[0068] In some embodiments, multiple groups of second clamping portions 122 are provided in the mounting groove 123 to increase the number of clamping points and enhance the strength of the connection.

[0069] The second clamping portion 122 on the mouth frame 12 is disposed within the mounting groove 123. During assembly, when the side of the inner liner 11 formed with the opening 112 extends into the mounting groove 123, the second clamping portion 122 can better cooperate with the first clamping portion 113 on the inner liner 11, thereby achieving a secure connection between the mouth frame 12 and the inner liner 11. The second clamping portion 122 is disposed within the mounting groove 123, making the clamping position more concealed and less susceptible to interference from external forces, thereby improving the stability of the connection between the mouth frame 12 and the inner liner 11. At the same time, the structure of the mouth frame 12 is more compact, reducing the space occupied, which is conducive to the rational use of the internal space of the refrigerator 100. Furthermore, the mounting groove 123 can provide positioning and guidance for the clamping fit, making it easier to locate the clamping connection between the inner liner 11 and the mouth frame 12 during installation, thereby improving the efficiency and accuracy of installation.

[0070] In some embodiments, see Figures 1 to 3 The distance between the second clamping portion 122 and the bottom of the mounting groove 123 is greater than or equal to 3 mm and less than or equal to 4 mm.

[0071] The specific size of the second clamping portion 122 from the bottom of the mounting groove 123 is not limited here, for example, it can be 3mm, 3.1mm, 3.2mm, 3.3mm, 3.4mm, 3.5mm, 3.6mm, 3.7mm, 3.8mm, 3.9mm, 4mm, etc.

[0072] If the second clip 122 is too close to the bottom of the mounting groove 123, the space between the second clip 122 and the first clip 113 will be too small, making the fit difficult. If the second clip 122 is too close to the bottom of the mounting groove 123, the first clip 113 will be too close to the edge opening 112, which will not improve the structural strength of the first clip 113 and reduce the fit. If the second clip 122 is too far from the bottom of the mounting groove 123, the depth of the mounting groove 123 will be too large, which will not be conducive to the molding of the mounting groove 123, and the structural volume will increase, which will not be conducive to cost control.

[0073] The distance between the second clamping portion 122 and the bottom of the installation groove 123 is controlled within the above range, which can ensure that the clamping fit has a certain structural strength while reducing the manufacturing cost.

[0074] In some embodiments, see Figures 1 to 3 The distance between the first clamping portion 113 and the opening 112 is greater than or equal to 3 mm and less than or equal to 4 mm.

[0075] The specific distance between the first clamping portion 113 and the opening 112 is not limited here, and can be, for example, 3 mm, 3.1 mm, 3.2 mm, 3.3 mm, 3.4 mm, 3.5 mm, 3.6 mm, 3.7 mm, 3.8 mm, 3.9 mm, 4 mm, etc.

[0076] The distance between the first clamping portion 113 and the opening 112 of the inner liner 11 is also specified, which must be greater than or equal to 3 mm and less than or equal to 4 mm, to ensure that the first clamping portion 113 cooperates with the second clamping portion 122 at a reasonable position.

[0077] In some embodiments, see Figures 1 to 3 The depth of the mounting groove 123 is greater than or equal to 10 mm and less than or equal to 11 mm.

[0078] The specific depth of the mounting groove 123 is not limited here, for example, it can be 10 mm, 10.1 mm, 10.2 mm, 10.3 mm, 10.4 mm, 10.5 mm, 10.6 mm, 10.7 mm, 10.8 mm, 10.9 mm, 11 mm, etc.

[0079] The depth of the mounting groove 123 refers to the dimension of the inner liner 11 in the direction of insertion into the mounting groove 123, which determines the degree of embedding of the inner liner 11 within the mounting groove 123. It is understood that a greater depth improves the embedding of the inner liner 11 within the mounting groove 123. However, a larger mounting groove 123 also increases manufacturing difficulties. Controlling the depth of the mounting groove 123 within this range ensures the embedding of the inner liner 11 within the mounting groove 123 while also controlling production costs.

[0080] In some embodiments, see Figures 1 to 3 The width of the mounting groove 123 is greater than or equal to 4 mm and less than or equal to 6 mm.

[0081] The specific size of the width of the mounting groove 123 is not limited here, for example, it can be 4mm, 4.2mm, 4.4mm, 4.6mm, 4.8mm, 5mm, 5.2mm, 5.4mm, 5.6mm, 5.8mm, 6mm, etc.

[0082] The width of the mounting slot 123 refers to the dimension within the plane of the mounting slot 123, perpendicular to the insertion direction of the liner 11 (i.e., the depth of the mounting slot 123) and perpendicular to the length of the mounting slot 123 (generally, the direction extending along the longer side of the mounting slot 123 corresponding to the outer dimensions of the liner 11). This dimension determines the amount of space available to accommodate the corresponding parts of the liner 11 and the liner 11 and related connecting structures.

[0083] When the width of the mounting groove 123 is smaller, the fit between the inner liner 11 and the mounting groove 123 will be tighter. For some application scenarios with high requirements for sealing, a smaller width can reduce the gap between the inner liner 11 and the mounting groove 123, thereby reducing the possibility of entry of external air, moisture, etc., and improving the overall sealing performance, but it increases the difficulty of fitting the inner liner 11 and the mounting groove 123. A larger width of the mounting groove 123 can meet some special design requirements. For example, when some additional structures (such as reinforcing ribs, sensor mounting positions, etc.) need to be set on the inner liner 11, and these structures need to be matched or installed through the mounting groove 123, a larger width can provide sufficient space. By controlling the width of the mounting groove 123 within the above range, while ensuring the embedding effect of the inner liner 11 in the mounting groove 123, a certain amount of space can also be reserved for installation.

[0084] In some embodiments, see Figures 1 to 3 The mounting groove 123 is sealed with the inner container 11 .

[0085] Here, the mounting groove 123 is sealed with the inner liner 11 to fill the gap between the mounting groove 123 and the inner liner 11, preparing for the subsequent filling of the gap between the inner liner 11 and the box body 2 with foaming agent, and preventing the foaming agent from overflowing from the gap between the mounting groove 123 and the inner liner 11 during the foaming process.

[0086] The form of sealing is not limited here, for example, sealing can be achieved by using a sealing strip.

[0087] In some embodiments, after the mounting groove 123 is fitted with the inner container 11, a circle of tape is wrapped around the mounting area to prevent the foaming agent from escaping from the gap. This sealing method is simple and effective, which helps reduce production costs and improve production efficiency.

[0088] In some embodiments, see Figures 1 to 3 One of the first clamping portion 113 and the second clamping portion 122 is a buckle 1131 , and the other is a clamping slot 1221 .

[0089] The buckle 1131 is a snap-fit structure with elastic deformation capability, usually having a protrusion or hook shape, and can be elastically deformed by applying a certain external force, thereby being snapped into or out of the slot 1221 .

[0090] The card slot 1221 is a card connection structure with a groove shape, which is used to accommodate the card buckle 1131. Its shape and size match the card buckle 1131 to achieve stable card connection.

[0091] The shape of the buckle 1131 is not limited here. For example, it can be a simple L-shaped buckle 1131, with one end fixed to the inner liner 11 or the mouth frame 12 and the other end being free and hook-shaped and capable of being snapped into the slot 1221. Alternatively, it can be a T-shaped buckle 1131, with a fixed middle portion and protruding structures at both ends as snap-fitting portions.

[0092] The shape and size of the slot 1221 must precisely match the buckle 1131. It can be a simple rectangular groove or an arc-shaped groove with a certain curvature to accommodate the different shapes of the buckle 1131. The depth of the slot 1221 should be moderate to ensure that the buckle 1131 is firmly inserted and easily removed.

[0093] The inner wall of the slot 1221 can be designed to have a certain degree of roughness or texture to increase the friction between the buckle 1131 and improve the stability of the clamping connection. For example, a frosted surface or some tiny protrusions can be used to prevent the buckle 1131 from sliding in the slot 1221.

[0094] Here, the first clamping portion 113 may be a buckle 1131 , and the second clamping portion 122 may be a corresponding slot 1221 . Alternatively, the first clamping portion 113 may be a slot 1221 , and the second clamping portion 122 may be a corresponding buckle 1131 .

[0095] In some embodiments, a stamping machine is used to process the slots 1221. For example, if three slots 1221 of the same size are required on the inner liner 11, the stamping machine is provided with three movable stamping dies. The spacing between the movable stamping dies can be adjusted to accommodate the machining of slots 1221 at different locations. After the relative positions of the three stamping dies are adjusted, all slots 1221 can be machined at once.

[0096] The inner liner 11 and the mouth frame 12 are fixedly connected using a simple yet effective snap-on connection method, namely, a buckle 1131 and a slot 1221. This method improves the strength of the connection between the inner liner 11 and the mouth frame 12. Compared to the related art, which requires wrapping tape around the mating joints during production and assembly, a process that can easily lead to collisions and damage between components on the production line, the buckle 1131 and slot 1221 connection method provides a more secure connection, reduces the number of tape wraps, and thus reduces the probability of collisions and improves product yield.

[0097] In some embodiments, see Figures 1 to 3 The length of the buckle 1131 is greater than or equal to 8 mm and less than or equal to 10 mm.

[0098] The specific length of the buckle 1131 is not limited here, for example, it can be 8mm, 8.2mm, 8.4mm, 8.6mm, 8.8mm, 9mm, 9.2mm, 9.4mm, 9.6mm, 9.8mm, 10mm, etc.

[0099] The length of the buckle 1131 refers to the dimension of the buckle 1131 in its main extension direction, parallel to the length direction of the slot 1221 when it is engaged with the slot 1221. This dimension mainly affects the insertion depth and engagement force of the buckle 1131 when engaged with the slot 1221.

[0100] It is understood that the larger the length of the buckle 1131, the more parts of the buckle 1131 connected to the slot 1221, and the greater the connection strength. However, a larger length of the buckle 1131 may interfere with other components during installation or reduce the elastic deformation ability of the buckle 1131, affecting the convenience of its insertion and removal from the slot 1221.

[0101] The length of the buckle 1131 is set within the above range, taking into account factors such as installation convenience, connection stability, and applicable scenarios. In actual application, the buckle 1131 of an appropriate length can be selected according to specific needs to achieve the best connection effect.

[0102] In some embodiments, see Figures 1 to 3 The length of the card slot 1221 is greater than or equal to 16 mm and less than or equal to 20 mm, and the width of the card slot 1221 is greater than or equal to 3 mm and less than or equal to 4 mm.

[0103] The specific length of the card slot 1221 is not limited here, for example, it can be 16mm, 16.2mm, 16.4mm, 16.6mm, 16.8mm, 17mm, 17.2mm, 17.4mm, 17.6mm, 17.8mm, 18mm, 18.2mm, 18.4mm, 18.6mm, 18.8mm, 19mm, 19.2mm, 19.4mm, 19.6mm, 19.8mm, 20mm, etc.

[0104] The specific size of the width of the card slot 1221 is not limited here, for example, it can be 3mm, 3.1mm, 3.2mm, 3.3mm, 3.4mm, 3.5mm, 3.6mm, 3.7mm, 3.8mm, 3.9mm, 4mm, etc.

[0105] The structure of the slot 1221 is determined by the structure of the buckle 1131. The length of the slot 1221 is greater than the length of the buckle 1131. This facilitates the fit between the slot 1221 and the buckle 1131. Furthermore, when multiple pairs of slots 1221 and buckles 1131 are provided, the larger slot 1221 provides a certain amount of assembly margin, which helps reduce manufacturing precision requirements.

[0106] In some embodiments, a guiding structure, such as a chamfer or a slope, may be provided at the entrance of the slot 1221 to facilitate the insertion of the buckle 1131 and improve installation efficiency.

[0107] The above-mentioned dimensional design enables the buckle 1131 to be securely engaged with the slot 1221, providing a stable connection. The length and width of the buckle 1131 and the slot 1221 match each other, ensuring sufficient contact area and engagement force in all directions, preventing the inner liner 11 and the mouth frame 12 from loosening or separating during use.
