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 the process of conceiving and implementing this application, the applicant discovered at least the following problems: Currently, when disassembling and assembling air duct covers, an air duct locking structure is generally set on the air duct cover. The air duct cover is installed by directly locking the air duct locking structure into the slot on the inner liner of the box, or the air duct locking structure is moved out of the slot to remove the air duct cover. During installation, the locking structure is prone to loosening or being too tight. When the locking structure is too tight, if the air duct cover needs to be repaired and disassembled later, the locking position of the inner liner may break, causing the locking structure to fail and thus damaging the inner liner.

[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 reduces the risk of damage to the inner liner caused by the air duct cover during installation or disassembly, and extends the service life of the inner liner.

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

[0007] The enclosure, including the inner liner;

[0008] The air duct cover is detachably located on the rear wall inside the inner liner of the box;

[0009] The snap-fit ​​assembly includes:

[0010] The snap-fit ​​component is detachably mounted on the duct cover.

[0011] The clamping assembly, located inside the box, includes:

[0012] The clamping element is rotatably mounted inside the box.

[0013] The elastic element connects the clamping element and the inner liner of the box;

[0014] The engaging member has a switchable engaging position and a disengaged position. When the engaging member moves from the disengaged position to the engaging position, the clamping member is configured to rotate to a first position under the compression of the engaging member and to provide compressive force to the elastic member.

[0015] When the engaging member moves from the engaging position to the disengaged position, the clamping member is configured to rotate to the second position under the elastic force of the elastic member.

[0016] The beneficial effects of this application are as follows: By fixing the clamping component inside the box, the air duct cover can be quickly installed and removed using the snap-fit ​​and clamping components. During the installation and removal of the air duct cover, the design of the snap-fit ​​and clamping components effectively avoids direct contact and friction with the box liner. Since direct force is avoided on the box liner, the risk of damage to the box liner due to improper force during installation or removal is reduced, thus extending the service life of the box liner. In addition, the air duct cover can be easily replaced and maintained without complicated tools or procedures.

[0017] Based on the above technical solution, the following improvements can be made to this application.

[0018] In some alternative implementations, when the engaging member moves from the disengaged position to the engaged position, the engaging member engages with the clamping member;

[0019] When the engaging component moves from the engaging position to the disengaged position, the engaging component disengages from the clamping component.

[0020] The above technical solution has the following advantages or beneficial effects: When the engaging component moves to the engaging position, it firmly engages with the clamping component, ensuring that the air duct cover will not loosen or fall off during use, thus improving the safety and reliability of the refrigerator operation. When it is necessary to remove the air duct cover, the engaging component can easily move from the engaging position to the disengaged position, separating from the clamping component, making the disassembly process quick and without the need for additional tools, thereby improving the convenience of operation.

[0021] In some alternative embodiments, the clamping member has:

[0022] Clamping groove for clamping the fastener; the opening size of the clamping groove is variable.

[0023] When the engaging component is in the clamping groove, the engaging component is in the engaged position;

[0024] When the engaging component is outside the clamping groove, the engaging component is in the disengaged position;

[0025] The size of the clamping groove when the clamping member is rotated to the first position is larger than the size of the clamping groove when the clamping member is rotated to the second position.

[0026] The above technical solution has the following advantages or beneficial effects: the groove size of the clamping slot is variable, allowing it to adapt to different positions of the engaging component. When the clamping component rotates to the first position, the groove size is larger, facilitating the engaging component to enter the clamping slot and securely clamp the engaging component; when rotated to the second position, the groove size decreases, indicating that the engaging component has disengaged. This adaptability ensures the stable fixation of the engaging component.

[0027] In some alternative implementations, the duct cover is provided with:

[0028] A sliding groove is located at the edge of the duct cover plate. The engaging component moves within the sliding groove to make the engaging component detachable relative to the duct cover plate.

[0029] The above technical solution has the following advantages or beneficial effects: the sliding groove allows the engaging component to move along the edge of the duct cover, enabling the engaging component to be disassembled relative to the duct cover. Through the design of the sliding groove, the engaging component can be easily detached from the clamping assembly simply by sliding it.

[0030] In some alternative implementations, the engaging component includes:

[0031] ontology;

[0032] The fastening part, connected to the first end of the body, is configured to engage or disengage with the clamping member;

[0033] A pulling part, connected to the first end of the main body, is configured to move within a sliding groove;

[0034] The extension direction of the fastening part is different from that of the pulling part.

[0035] The above technical solution has the following advantages or beneficial effects: the pulling part moves in the sliding groove, allowing the user to easily control the position of the locking part. Even in situations where space is limited, the air duct cover can be disassembled through a simple sliding action, improving the convenience of operation.

[0036] In some alternative implementations, the clamping assembly further includes:

[0037] The base is located on the inner wall of the inner liner of the box;

[0038] The clamping element is rotatably mounted on the base, and the elastic element connects the clamping element and the base.

[0039] The above technical solution has the following advantages or beneficial effects: the base is fixed to the inner wall of the box liner, providing stable support for the clamping component. This makes the rotation and engagement of the clamping component smoother, reducing the risk of misoperation due to instability. The base provides a fixed rotation axis, making the rotation of the clamping component smoother, reducing wear and material fatigue caused by friction, and extending the service life of the components.

[0040] In some alternative implementations, the clamping assembly further includes:

[0041] The fastener is located on the outer wall of the inner liner of the box;

[0042] Fasteners, bases, and fixtures are secured to the inner and outer side walls of the inner liner using fasteners.

[0043] The above technical solution has the following advantages or beneficial effects: The base and fixing components are secured to the inner and outer side walls of the inner liner using fasteners, forming a robust clamping structure. This design improves the overall stability of the clamping assembly, ensuring that it will not loosen or shift during use.

[0044] In some alternative implementations, the clamping element includes:

[0045] The first clamping element is rotatably mounted at one end of the base;

[0046] The second clamping member is rotatably located at the other end of the base, and the second clamping member and the first clamping member are hinged to each other;

[0047] When the engaging member moves to the engaging position, the first clamping member and the second clamping member rotate in opposite directions;

[0048] When the engaging member moves to the engaging position, the first clamping member and the second clamping member rotate towards each other.

[0049] When the engaging member moves to the disengaged position, the first clamping member and the second clamping member rotate in opposite directions.

[0050] The above technical solution has the following advantages or beneficial effects: the first clamping member and the second clamping member are hinged to each other. When the engaging member moves to the engaging position, the two clamping members first rotate in opposite directions and then rotate in opposite directions, providing greater clamping force and stability, and ensuring that the engaging member is firmly fixed.

[0051] The clamping components rotate in opposite directions under the elastic force of the elastic element to automatically reset, thereby reducing the clamping space.

[0052] In some alternative implementations, the elastic element includes:

[0053] The first elastic element is connected between the abutting end of the first clamping element and the first end of the base;

[0054] The second elastic element is connected between the abutting end of the second clamping element and the second end of the base.

[0055] The above technical solution has the following advantages or beneficial effects: the first elastic element and the second elastic element provide independent elastic support for the first clamping element and the second clamping element, respectively. This design ensures that each clamping element receives appropriate elastic force during operation, enhancing the stability and responsiveness of the clamping elements.

[0056] In some alternative implementations, the groove wall of the clamping groove is arc-shaped and matches the shape of the outer wall of the engaging member.

[0057] The above technical solution has the following advantages or beneficial effects: the matching design of the arc-shaped groove wall and the outer wall of the engaging component increases the contact area between them. This increased contact area helps to distribute pressure, improve clamping force, and ensure the stability of the engaging component within the groove.

[0058] The refrigerator provided in this application includes a cabinet, including an inner liner; an air duct cover, detachably disposed on the rear wall inside the inner liner; a latching assembly, including: a latching member, detachably disposed on the air duct cover; a clamping assembly disposed on the inner liner, the clamping assembly including: a clamping member, rotatably disposed on the inner liner; an elastic member, connected between the clamping member and the inner liner; the latching member has a switchable latching position and a disengaged position, when the latching member moves from the disengaged position to the latching position, the clamping member is configured to rotate to a first position under the compression of the latching member, and provides a compressive force to the elastic member; when the latching member moves from the latching position to the disengaged position, the clamping member is configured to rotate to a second position under the elastic force of the elastic member.

[0059] By fixing the clamping assembly inside the casing, the duct cover can be quickly installed and removed using the snap-fit ​​and clamping components. During the installation and removal of the duct cover, the design of the snap-fit ​​and clamping components effectively avoids direct contact and friction with the casing. By avoiding direct force on the casing, the risk of damage to the casing caused by improper force during installation or removal is reduced, thus extending the service life of the casing. In addition, the duct cover can be easily replaced and maintained without complicated tools or procedures. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. All other obtained embodiments are within the scope of protection of this application. In the absence of conflict, the following embodiments and features can be combined with each other.

[0084] Currently, when installing or removing duct covers, a duct locking structure is typically installed on the duct cover. This structure directly engages with a slot on the inner liner of the enclosure to install the duct cover, or the duct locking structure can be removed from the slot to remove the duct cover. However, during installation, the locking mechanism can easily become loose or too tight. If the locking mechanism is too tight, it may cause the locking point on the inner liner to crack during later maintenance or disassembly of the duct cover, resulting in locking failure and ultimately damaging the inner liner.

[0085] To overcome the shortcomings of the prior art, the refrigerator provided in this application, by fixing the clamping assembly inside the refrigerator liner, can achieve quick installation and removal of the air duct cover using the snap-fit ​​and clamping assembly. During the installation and removal of the air duct cover, the design of the snap-fit ​​and clamping assembly effectively avoids direct contact and friction with the refrigerator liner. By avoiding direct force on the refrigerator liner, the risk of damage to the refrigerator liner due to improper force during installation or removal is reduced, thus extending the service life of the refrigerator liner. In addition, the air duct cover can be easily replaced and maintained without complicated tools or procedures.

[0086] 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.

[0088] like Figures 1 to 8 As shown, this application embodiment provides a refrigerator 100, including:

[0089] Refrigerator 100, including:

[0090] Box body 110, including inner liner 111;

[0091] The air duct cover 130 is detachably installed on the rear wall inside the inner liner 111 of the box;

[0092] Clip assembly 140 includes:

[0093] The snap-fit ​​component 150 is detachably mounted on the air duct cover 130;

[0094] Clamping assembly 160 is disposed in the inner liner 111 of the box. Clamping assembly 160 includes:

[0095] Clamping component 161 is rotatably mounted inside the box liner 111;

[0096] The elastic element 162 is connected between the clamping element 161 and the inner liner 111;

[0097] The engaging member 150 has a switchable engaging position and a disengaged position. When the engaging member 150 moves from the disengaged position to the engaging position, the clamping member 161 is configured to rotate to a first position under the compression of the engaging member 150 and to provide a compressive force to the elastic member 162.

[0098] When the engaging member 150 moves from the engaging position to the disengaged position, the clamping member 161 is configured to rotate to the second position under the elastic force of the elastic member 162.

[0099] With the above-described configuration, i.e., the refrigerator 100 of this application embodiment, by fixing the clamping component 160 inside the inner liner 111, can quickly install and remove the air duct cover 130 using the engaging component 150 and the clamping component 160. During the installation and removal of the air duct cover 130, the design of the engaging component 150 and the clamping component 160 effectively avoids direct contact and friction with the inner liner of the refrigerator 100. Since direct force is avoided on the inner liner 111, the risk of damage to the inner liner due to improper force during installation or removal is reduced, and the service life of the inner liner of the refrigerator 100 is extended. In addition, the air duct cover 130 can be easily replaced and maintained without complicated tools or steps.

[0100] It should be noted that the following provides a detailed explanation of each structure.

[0101] [Box 110]

[0102] 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.

[0103] 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.

[0104] 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.

[0105] In some embodiments, a refrigeration assembly (not shown) is provided inside the cabinet 110 to provide refrigeration for the interior of the refrigerator 100 in order to maintain a low-temperature environment in each refrigeration compartment.

[0106] Refrigeration components include compressors, condensers, evaporators, and throttling devices. The specific structure and connections of these components can be found in relevant technical documentation on refrigeration components, and will not be elaborated upon here. The evaporator provides different amounts of cooling capacity to different types of storage spaces, resulting in varying temperatures within these spaces. For example, the temperature inside a refrigerator is generally between 2°C and 10°C, preferably between 4°C and 7°C. The temperature range inside a freezer is generally between -22°C and -14°C. Different types of items have different optimal storage temperatures, and consequently, different suitable storage spaces. For example, fruits and vegetables are suitable for storage in refrigerators or crisper compartments, while meat is suitable for storage in freezers.

[0107] [Gate 120]

[0108] It should be noted that the door 120 can be connected to the cabinet 110 to open or close the refrigeration compartment.

[0109] 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.

[0110] 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.

[0111] In some embodiments, the door 120 is a rotating door structure. The door 120 is rotatably disposed on the front side of the cabinet 110, and in this case, the door 120 can be used as a general door structure, such as a refrigerator door, a freezer door, etc.

[0112] 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 of the refrigerator 100 and opening and closing the corresponding refrigeration compartment.

[0113] 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.

[0114] [Airflow Components]

[0115] It should be noted that the refrigerator 100 also includes an air duct assembly, which is located inside the inner liner 111 and on the rear wall of the inner liner 111. A cooling compartment is formed on the front side of the air duct assembly, which is located on the back side of the corresponding cooling compartment inside the inner liner 111. The air duct assembly is used to form an air supply duct (not shown in the figure) in the inner liner 111. This air supply duct connects to the cooling compartment on the front side of the air duct assembly, thereby delivering cold air from the refrigerator 100 into the corresponding cooling compartment through the air supply duct, thus achieving the cooling function of the corresponding cooling compartment.

[0116] In some embodiments, an air supply duct is recessed and formed on the back side of the duct assembly. When the duct assembly is installed on the rear wall inside the inner liner 111, the air supply duct can be formed between the back side of the duct assembly and the rear wall inside the inner liner 111.

[0117] It should be noted that in other embodiments, the air supply duct may also be formed separately inside the duct assembly.

[0118] In some embodiments, a duct mounting groove is recessed on the rear wall inside the inner liner 111, and the duct assembly is installed in the duct mounting groove. When the duct assembly is installed in the duct mounting groove inside the inner liner 111, the air supply duct can also be formed between the back side of the duct assembly and the rear wall of the duct mounting groove.

[0119] In some embodiments, the duct assembly includes a duct cover 130 and duct foam. The duct cover 130 is generally plate-shaped and covers the front opening of the duct mounting groove. The duct cover 130 is arranged parallel or substantially parallel to the rear wall of the inner liner 111. The space on the front side of the duct cover 130 is used to form a cooling compartment, and the space between the back side of the duct cover 130 and the rear wall of the inner liner 111 is used to provide installation space for the air supply duct.

[0120] In some embodiments, the duct foam is fixed to the back side of the duct cover plate 130, and the air supply duct is recessed and formed on the back side of the duct foam.

[0121] The duct foam can be made of foam material. Therefore, when the duct cover 130 is placed over the front opening of the duct mounting groove, the duct foam is sandwiched between the back side of the duct cover 130 and the rear wall inside the inner liner 111, and the air supply duct is formed between the back side of the duct foam and the rear wall of the duct mounting groove inside the inner liner 111.

[0122] It should be noted that in other embodiments, the duct foam may also be made of other insulation materials.

[0123] [Snap-on assembly 140]

[0124] It should be noted that the refrigerator 100 also includes a snap-fit ​​assembly 140, the purpose of which is to allow the air duct cover 130 to be detachably mounted on the inner liner 111.

[0125] In some embodiments, the snap-fit ​​assembly 140 includes a snap-fit ​​member 150, wherein the snap-fit ​​member 150 is disposed on the air duct cover 130.

[0126] In some embodiments, the snap-fit ​​assembly 140 further includes a clamping assembly 160, wherein the clamping assembly 160 is disposed in the inner liner 111, and the assembly state of the air duct cover 130 and the inner liner 111 is realized by the assembly state of the snap-fit ​​member 150 and the clamping assembly 160.

[0127] Specifically, the clamping assembly 160 includes a clamping member 161, which is rotatable relative to the inner liner 111 of the box, and can be rotated to a first position or a second position.

[0128] The clamping assembly 160 may also include an elastic element 162, wherein the elastic element 162 is located between the clamping member 161 and the inner liner 111, and can provide a pushing force to the clamping member 161 through its own elastic deformation.

[0129] It should be noted that the engaging component 150 has a switchable engaging position and a disengaged position. That is, the engaging component 150 can move from the engaging position to the disengaged position, and it can also move from the disengaged position to the engaging position. The other structural changes brought about by the engaging component 150 moving to different positions can be specifically described below.

[0130] When the engaging member 150 moves from the disengaged position to the engaged position, the engaging member 150 gradually approaches the clamping member 161 until it engages with the clamping member 161. At this time, the clamping member 161 rotates to the first position under the pressure of the engaging member 150. When the clamping member 161 rotates to the first position, the clamping member 161 rotates towards the rear wall facing the inner liner 111, thereby shortening the distance between the clamping member 161 and the rear wall of the inner liner 111, thereby compressing the elastic member 162, so that the elastic member 162 is in a compressed state.

[0131] When the engaging member 150 moves from the engaging position to the disengaged position, the engaging state between the engaging member 150 and the clamping member 161 switches to the disengaged state. This means that the engaging member 150 disengages from the clamping member 161. At this time, the clamping member 161 is freed from the compression of the engaging member 150 and rotates again under the elastic force of the elastic member 162. It rotates to the second position, and the clamping member 161 rotates away from the rear wall of the inner liner 111, thereby lengthening the distance between the clamping member 161 and the rear wall of the inner liner 111 until the elastic member 162 returns to its original natural state.

[0132] Of course, the return of the elastic element 162 to its natural state can be understood as its original natural state. However, considering practical factors, the end of the elastic element 162 supports the clamping element 161, and the weight of the clamping element 161 itself will undoubtedly be applied to the elastic element 162. Therefore, the elastic element 162 at this time is not in a truly natural state, but only has recovered relative to the elastic element 162 when the clamping element 161 rotates to the first position. Alternatively, it can be understood that the compression of the elastic element 162 when the clamping element 161 rotates to the first position is greater than the compression of the elastic element 162 when the clamping element 161 rotates to the second position.

[0133] In some embodiments, the elastic element 162 may be a compression spring.

[0134] In other embodiments, the elastic element 162 may also be other structural elements with deformation.

[0135] It should be noted that since the duct cover 130 is removable, users can easily clean and maintain it, reducing the complexity of cleaning the internal duct and improving the user experience.

[0136] The engaging component 150 and the clamping component 160 in the snap-fit ​​assembly 140 cooperate to provide a stable fixing mechanism. When the engaging component 150 is in the engaged position, the rotation of the clamping component 161 and the action of the elastic component 162 ensure that the air duct cover 130 is firmly fixed to the rear wall of the inner liner 111. When the engaging component 150 moves from the engaged position to the disengaged position, the clamping component 161 automatically resets under the action of the elastic component 162, simplifying the disassembly process. Users do not need to manually adjust the position of the clamping component 161, improving the convenience of operation.

[0137] In addition, the elastic element 162 provides a buffering effect during the clamping process, which can effectively reduce the vibration and noise generated by the operation of the refrigerator 100 and improve the overall quietness of the refrigerator 100.

[0138] like Figures 5 to 8 As shown, in some optional embodiments, when the engaging member 150 moves from the disengaged position to the engaged position, the engaging member 150 engages with the clamping member 161.

[0139] When the engaging member 150 moves from the engaging position to the disengaged position, the engaging member 150 disengages from the clamping member 161.

[0140] The above technical solution has the following advantages or beneficial effects: When the engaging component 150 moves to the engaging position, it is firmly engaged with the clamping component 161, ensuring that the air duct cover 130 will not loosen or fall off during use, thus improving the safety and reliability of the refrigerator 100. When it is necessary to remove the air duct cover 130, the engaging component 150 can easily move from the engaging position to the disengaged position, separating from the clamping component 161, making the disassembly process quick and without the need for additional tools, thus improving the convenience of operation.

[0141] Specifically, users can easily install and remove the duct cover 130 by simply moving the card assembly 150. The operation is simple and intuitive, reducing the difficulty of use.

[0142] In addition, the robust locking mechanism reduces the risk of the air duct cover 130 accidentally falling off, ensuring the safety of the refrigerator 100's interior and preventing malfunctions or damage caused by loose parts.

[0143] Figure 9 This is a schematic diagram showing the engagement state of the inner liner of the refrigerator compartment and the air duct cover provided in an embodiment of this application. Figure 10 This is a cross-sectional view of the refrigerator's central air duct cover and the snap-fit ​​assembly provided in an embodiment of this application. Figure 11 This is a schematic diagram of the structure of the refrigerator latching component with the clamping groove provided in the embodiment of this application.

[0144] like Figures 5 to 11 As shown, in some alternative embodiments, the clamping member 161 has a clamping groove 1613 to clamp the engaging member 150, and the groove size of the clamping groove 1613 is variable.

[0145] When the engaging member 150 is located inside the clamping groove 1613, the engaging member 150 is in the engaging position; when the engaging member 150 is located outside the clamping groove 1613, the engaging member 150 is in the disengaged position.

[0146] The size of the clamping groove 1613 when the clamping member 161 is rotated to the first position is greater than the size of the clamping groove 1613 when the clamping member 161 is rotated to the second position.

[0147] The above technical solution has the following advantages or beneficial effects: the opening size of the clamping groove 1613 is variable, allowing it to adapt to different positions of the engaging member 150. When the clamping member 161 rotates to the first position, the opening size is larger, facilitating the engaging member 150 to enter the clamping groove 1613 and securely clamp the engaging member 150; when rotated to the second position, the opening size decreases, indicating that the engaging member 150 has disengaged. This adaptability ensures the stable fixation of the engaging member 150.

[0148] It should be noted that the disengagement position can include the fully disengaged position and the pre-disengagement position. In this article, the disengagement position refers to the fully disengaged position.

[0149] The pre-disengagement position refers to the position where at least a portion of the clamping member 161 moves outside the clamping groove 1613, thus allowing the duct cover 130 to disengage from the inner liner 111. During installation, the clamping member 161 needs to be moved from the fully disengaged state to the engaged state.

[0150] like Figure 10 and Figure 11 As shown, in some optional embodiments, the duct cover 130 is provided with a sliding groove 131 located at the edge of the duct cover 130, and the engaging member 150 moves within the sliding groove 131 so that the engaging member 150 is detachable relative to the duct cover 130.

[0151] The above technical solution has the following advantages or beneficial effects: the sliding groove 131 allows the engaging member 150 to move along the edge of the duct cover 130, so that the engaging member 150 can be disassembled relative to the duct cover 130. Through the design of the sliding groove 131, the engaging member 150 can be easily detached from the clamping assembly 160 simply by sliding it.

[0152] The sliding groove 131 provides a guide path to ensure that the engaging member 150 remains stable during movement and does not deviate from the predetermined position, which helps to accurately align the clamping member 161 during installation and improves the stability of the overall structure.

[0153] The sliding groove 131 design reduces friction and wear between the engaging component 150 and the duct cover 130, extending the service life of the components. The sliding groove 131 design allows the duct cover 130 to adapt to different installation requirements, and users can adjust the position of the engaging component 150 according to specific circumstances, increasing the system's adaptability and flexibility.

[0154] It should be noted that when it is necessary to remove the air duct cover 130, it is only necessary to move the locking part 150 at least partially outside the sliding groove 131.

[0155] Figure 12 This is a schematic diagram showing the engaged state of the locking component and clamping assembly in a refrigerator, as provided in an embodiment of this application. Figure 13 This is a schematic diagram showing the refrigerator's locking and clamping components detached, as provided in an embodiment of this application.

[0156] like Figures 10 to 13 As shown, in some alternative embodiments, the latching member 150 includes a body 151.

[0157] The engaging member 150 also includes a fastening part 152 connected to the first end of the body 151, the fastening part 152 being configured to engage or disengage with the clamping member 161.

[0158] The engaging member 150 also includes a pull part 153 connected to the first end of the body 151, the pull part 153 being configured to move within the sliding groove 131.

[0159] The extension direction of the fastening part 152 is different from the extension direction of the pulling part 153.

[0160] The above technical solution has the following advantages or beneficial effects: the pulling part 153 moves in the sliding groove 131, allowing the user to easily control the position of the locking part 150. Even in situations where space is limited, the air duct cover 130 can be disassembled through a simple sliding action, improving the convenience of operation.

[0161] It should be noted that, since the extension directions of the fastening part 152 and the pulling part 153 are different, the user can realize the operation of the locking member 150 by moving the pulling part 153 in the sliding groove 131 without affecting the engagement or disengagement of the fastening part 152 and the clamping member 161.

[0162] The latching part 152 is specifically designed to engage or disengage with the clamping part 161. Its direction is independent of the pulling part 153, ensuring a stable fixing effect in the engaged state and preventing accidental loosening.

[0163] In some embodiments, the body 151, the fastening part 152, and the pulling part 153 are integrally formed structural parts, which can improve the strength of the fastening part 150.

[0164] In some embodiments, the pull part 153 can be a handle, which facilitates the application of force by maintenance personnel during installation or disassembly.

[0165] When disassembling the duct cover 130, simply pull the pulling part 153 outward so that part of the fastening part 152 is outside the sliding groove 131. Continue pulling the whole thing until the fastening part 152 is completely disengaged from the clamping member 161.

[0166] In some embodiments, there are multiple snap-fit ​​components 140, multiple snap-fit ​​members 150, and multiple clamping components 160. The multiple snap-fit ​​members 150 are spaced apart along the extension direction of the air duct cover 130, and the multiple clamping components 160 are spaced apart along the extension direction of the inner liner 111.

[0167] like Figure 12 and Figure 13 As shown, in some optional embodiments, the clamping assembly 160 further includes:

[0168] The base 163 is located on the inner wall of the inner liner 111 of the box;

[0169] The clamping member 161 is rotatably mounted on the base 163, and the elastic member 162 is connected between the clamping member 161 and the base 163.

[0170] The above technical solution has the following advantages or beneficial effects: The base 163 is fixed to the inner wall of the inner liner 111, providing stable support for the clamping component 161. This makes the rotation and engagement of the clamping component 161 smoother, reducing the risk of misoperation due to instability. The base 163 provides a fixed rotation axis, making the rotation of the clamping component 161 smoother, reducing wear and material fatigue caused by friction, and extending the service life of the component.

[0171] Furthermore, the elastic element 162 connects between the clamping member 161 and the base 163, providing continuous elastic pressure. This design ensures that the clamping member 161 can firmly secure the engaging member 150 in the engaged state, enhancing the overall structural stability.

[0172] The introduction of the elastic element 162 allows the clamping element 161 to automatically return to its initial position after disengaging from the engaging element 150. This automatic reset function simplifies the operation process, eliminating the need for users to manually adjust the position of the clamping element 161 and improving ease of use.

[0173] The stable base 163 and the elastic element 162 ensure that the clamping element 161 will not accidentally fall off or fail during use, thus improving the safety of the internal structure of the refrigerator 100.

[0174] In some embodiments, the clamping assembly 160 further includes a rotating member 166, which can satisfy the rotation of the clamping member 161 under the action of the rotating member 166.

[0175] For example, the rotating element 166 can be a rotating shaft.

[0176] like Figures 10 to 13 As shown, in some optional embodiments, the clamping assembly 160 further includes:

[0177] Fastener 164 is located on the outer wall of the inner liner 111 of the box;

[0178] Fastener 165, base 163 and fixing member 164 are fixed to the inner and outer side walls of the inner liner 111 by fastener 165.

[0179] The above technical solution has the following advantages or beneficial effects: the base 163 and the fixing member 164 are fixed to the inner and outer side walls of the inner liner 111 by the fastener 165, forming a solid clamping structure. This design improves the overall stability of the clamping assembly 160, ensuring that it will not loosen or shift during use.

[0180] It should be noted that the use of fastener 165 allows the base 163 and the fixing member 164 to share the force from the clamping member 161. This uniform force distribution reduces the pressure on a single side wall of the inner liner 111, lowering the risk of material fatigue and deformation. The design of fastener 165 also simplifies the installation and removal of the base 163 and the fixing member 164, allowing users to quickly maintain and replace components, thus improving operational efficiency.

[0181] The fastener 164, located on the outer wall of the inner liner 111, provides additional support and fixing points, making the entire clamping assembly 160 more secure and reducing the possibility of loosening due to vibration or impact.

[0182] In some embodiments, the fastener 165 can be a bolt fastener 165. Mounting holes are respectively provided on the fixing member 164, the inner liner 111, and the base 163 to facilitate the fastener 165 passing through, thereby tightening or loosening to achieve installation or removal between the fixing member 164 and the base 163. Accordingly, the mounting holes can be threaded holes.

[0183] like Figure 12 and Figure 13 As shown, in some alternative embodiments, the clamping member 161 includes:

[0184] The first clamping member 1611 is rotatably mounted on one end of the base 163;

[0185] The second clamping member 1612 is rotatably disposed at the other end of the base 163, and the second clamping member 1612 and the first clamping member 1611 are hinged to each other.

[0186] When the engaging member 150 moves to the engaging position, the first clamping member 1611 and the second clamping member 1612 rotate in opposite directions.

[0187] like Figure 12 As shown, when the engaging member 150 moves to the engaging position, the first clamping member 1611 and the second clamping member 1612 rotate toward each other.

[0188] like Figure 13 As shown, when the engaging member 150 moves to the disengaged position, the first clamping member 1611 and the second clamping member 1612 rotate toward each other.

[0189] The above technical solution has the following advantages or beneficial effects: the first clamping member 1611 and the second clamping member 1612 are hinged to each other. When the engaging member 150 moves to the engaging position, the two clamping members 161 first rotate in opposite directions and then rotate in opposite directions, providing greater clamping force and stability, and ensuring that the engaging member 150 is firmly fixed.

[0190] Due to the hinged design of the clamping members 161, when the engaging member 150 moves, the clamping members 161 can automatically adjust their position and angle to adapt to the movement of the engaging member 150.

[0191] When the engaging member 150 moves from the disengaged position to the engaged position, the first clamping member 1611 and the second clamping member 1612 rotate in opposite directions to provide a larger clamping space. When the engaging member 150 is engaged in the clamping groove 1613, the elastic member 162 pushes the clamping member 161 upward, so that the first clamping member 1611 and the second clamping member 1612 can rotate in opposite directions to lock the engaging member 150 and fix the air duct cover 130 to the rear wall inside the inner liner 111.

[0192] When the engaging member 150 moves from the engaging position to the disengaged position, the pulling part 153 moves within the sliding groove 131, causing the engaging part 152 to disengage from the clamping groove 1613. At this time, the first clamping member 1611 and the second clamping member 1612 rotate towards each other under the elastic force of the elastic member 162 to automatically reset, thereby reducing the clamping space.

[0193] like Figure 12 and Figure 13 As shown, in some optional embodiments, the elastic element 162 includes:

[0194] The first elastic element 1621 is connected between the abutting end of the first clamping element 1611 and the first end of the base 163;

[0195] The second elastic element 1622 is connected between the abutting end of the second clamping element 1612 and the second end of the base 163.

[0196] The above technical solution has the following advantages or beneficial effects: the first elastic element 1621 and the second elastic element 1622 provide independent elastic support for the first clamping element 1611 and the second clamping element 1612, respectively. This design ensures that each clamping element 161 can obtain appropriate elastic force during operation, thereby enhancing the stability and responsiveness of the clamping element 161.

[0197] By providing a first elastic element 1621 to the first clamping member 1611 and a second elastic element 1622 to the second clamping member 1612, when the engaging member 150 moves to the engaging position, the first elastic element 1621 and the second elastic element 1622 provide additional clamping force to ensure that the engaging member 150 is firmly fixed and prevents loosening.

[0198] The introduction of the first elastic element 1621 and the second elastic element 1622 enables the first clamping element 1611 and the second clamping element 1612 to automatically return to their initial positions after disengaging from the engaging element 150. This automatic reset function simplifies the operation process, eliminating the need for users to manually adjust the positions of the first clamping element 1611 and the second clamping element 1612, thus improving ease of use.

[0199] In some embodiments, the first elastic element 1621 and the second elastic element 1622 may be compression springs.

[0200] In some embodiments, the first clamping member 1611 and the second clamping member 1612 may be rod-shaped structural members.

[0201] In some alternative embodiments, the groove wall of the clamping groove 1613 is arc-shaped and matches the shape of the outer wall of the engaging member 150.

[0202] The above technical solution has the following advantages or beneficial effects: the matching design of the arc-shaped groove wall and the outer wall of the engaging member 150 increases the contact area between them. This increased contact area helps to distribute pressure, improve clamping force, and ensure the stability of the engaging member 150 within the groove.

[0203] Because the curved surface matches the shape of the outer wall of the snap-fit ​​150, friction from sharp edges or irregular surfaces that may occur during installation and disassembly is reduced, thereby lowering the risk of wear and material fatigue.

[0204] The refrigerator provided in this application includes a cabinet, including an inner liner; an air duct cover, detachably disposed on the rear wall inside the inner liner; a latching assembly, including: a latching member, detachably disposed on the air duct cover; a clamping assembly disposed on the inner liner, the clamping assembly including: a clamping member, rotatably disposed on the inner liner; an elastic member, connected between the clamping member and the inner liner; the latching member has a switchable latching position and a disengaged position, when the latching member moves from the disengaged position to the latching position, the clamping member is configured to rotate to a first position under the compression of the latching member, and provides a compressive force to the elastic member; when the latching member moves from the latching position to the disengaged position, the clamping member is configured to rotate to a second position under the elastic force of the elastic member.

[0205] By fixing the clamping assembly inside the casing, the duct cover can be quickly installed and removed using the snap-fit ​​and clamping components. During the installation and removal of the duct cover, the design of the snap-fit ​​and clamping components effectively avoids direct contact and friction with the casing. By avoiding direct force on the casing, the risk of damage to the casing caused by improper force during installation or removal is reduced, thus extending the service life of the casing. In addition, the duct cover can be easily replaced and maintained without complicated tools or procedures.
