Abstract

This application discloses a refrigerator, belonging to the field of refrigeration equipment technology, aiming to solve the technical problem of large lateral misalignment between the lid and the storage drawer when the drawer is closed. The refrigerator includes a cabinet, a storage drawer, and a lid. An elastic element is provided within a guide rail in the cabinet structure for sliding engagement with the lid. When the storage drawer is closed, the elastic element is located outside the mating part of the lid that engages with the guide rail, and elastically presses against the mating part to reduce the lateral freedom of the lid.

Description

Technical Field

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

[0002] Refrigerators are usually equipped with storage drawers, and the top of the storage drawers is equipped with a cover. When the storage drawer is closed, the cover closes the drawer opening to extend the shelf life of the food inside.

[0003] In related technologies, as the storage drawer is gradually pulled out from the closed state, the lid rises relative to the drawer body by a certain distance to separate the lid from the drawer, reducing the likelihood of the drawer rubbing against the lid during the pull-out process and improving the smoothness of the drawer's movement. During the closing process, the lid falls back down to close on top of the drawer when it is in the closed state.

[0004] However, when the storage drawer is closed, the lid is misaligned laterally relative to the drawer, resulting in misalignment and making it difficult to seal the drawer. Summary of the Invention

[0005] This application provides a refrigerator that solves the technical problem of large lateral misalignment of the lid relative to the storage drawer when the drawer is closed.

[0006] This application provides a refrigerator, including:

[0007] The enclosure forms a refrigeration compartment; the side walls of the refrigeration compartment are equipped with guide rails.

[0008] Storage drawers, which can be pulled out and installed in the refrigeration room;

[0009] The cover, located in the refrigeration compartment, is configured as the drawer opening for opening or closing a storage drawer; the cover has mating parts at both ends along the width of the cabinet, and the mating parts move relative to each other along the guide rail; when the storage drawer is in the closed state, the cover closes onto the drawer opening;

[0010] The side wall of the compartment is also provided with an elastic element, at least part of which extends into the guide rail. When the storage drawer is closed, the elastic element is located outside the mating part along the width direction of the cabinet and is elastically pressed against the mating part.

[0011] In the refrigerator of this embodiment, the extrusion force of the elastic member on the mating member acts on the outer side of the mating member along the width direction of the cabinet, thus enabling the lid to be laterally guided. This allows the lid to gradually correct its lateral sway as it approaches the drawer opening and stably fall into the predetermined closed position. When the storage drawer is closed, the degree of lateral misalignment between the lid and the storage drawer is reduced, improving the alignment accuracy between the lid and the storage drawer in the lateral direction, thereby improving the sealing effect of the lid on the drawer opening.

[0012] In some embodiments of this application, the elastic element is an elastic arm, and the two ends of the elastic arm extending in the direction of extension have a fixed end and a movable end, respectively.

[0013] The fixed end is connected to the side wall of the compartment, and the movable end extends inclined toward the cover into the guide rail;

[0014] When the storage drawer is closed, the movable end or the part of the elastic arm near the movable end is elastically pressed against the mating part.

[0015] With this configuration, the elastic arm provides limiting and return capabilities to the mating parts by relying on its own elastic recovery. It can maintain stable contact pressure and guiding effect after multiple opening and closing cycles, which helps to improve the alignment accuracy, sealing reliability and vacuum retention capability of the storage drawer when it is closed.

[0016] In some embodiments of this application, the movable end is located on the side of the fixed end opposite to the pull-out direction of the storage drawer.

[0017] With this configuration, the side of the elastic arm facing the lid forms a guide surface that slopes towards the refrigeration compartment along the depth direction of the cabinet. As the storage drawer gradually closes from the open state, this guide surface guides the mating parts, allowing them to slide gradually into the movable end area along the guide surface and elastically press against the elastic arm at the movable end. This reduces the possibility of interference or jamming between the mating parts and the elastic arm, improving the stability of the lid's movement.

[0018] In some embodiments of this application, the elastic arm includes a connected tilting section and a clamping section;

[0019] The end of the inclined section away from the clamping section is the fixed end; the inclined section extends at an angle relative to the depth direction of the box, and the end of the inclined section away from the fixed end is closer to the cover than the fixed end;

[0020] The clamping section is located inside the guide rail, and the end of the clamping section away from the inclined section is the movable end; the clamping section extends along the depth direction of the housing;

[0021] When the storage drawer is closed, the clamping section and the mating part are elastically pressed together.

[0022] This design creates a continuous transition structure between the tilting section and the clamping section, which first guides the contents in and then clamps them in. This reduces the possibility of sudden collisions or jumping at the closing end of the mating parts. Instead, it gradually corrects the position and stabilizes the force, thus improving the lateral stability of the lid when it is closed, reducing shaking and misalignment, and thereby improving the sealing accuracy between the lid and the drawer opening.

[0023] In some embodiments of this application, the side wall of the compartment located on the side of the guide rail away from the cover is provided with a clearance opening, the fixed end is connected to the edge of the clearance opening, the projection of the elastic arm on the side wall of the compartment is located inside the clearance opening, and the clearance opening is configured to allow the movable end to pass through.

[0024] This configuration allows the clearance opening to provide passage space for the movable end of the flexible arm and forms a local deformation area, enabling the flexible arm to obtain sufficient elastic displacement without increasing the overall installation space.

[0025] In some embodiments of this application, the guide rail includes a forward rail and a lifting rail arranged and connected along the pull-out direction of the storage drawer;

[0026] The forward guide rail extends along the depth direction of the housing;

[0027] One end of the lifting rail is connected to the forward rail, and the end of the lifting rail away from the forward rail extends upward at an angle.

[0028] The elastic element is located inside the forward guide rail;

[0029] When the storage drawer is closed, the mating part moves to the end of the forward slide rail away from the lifting rail and is elastically pressed against the elastic part.

[0030] When the storage drawer is open, the mating component moves to the end of the lifting rail away from the forward rail.

[0031] With this configuration, when the mating parts move to the end of the forward rail away from the lifting rail, they are guided to a more stable fitting position by the elastic recovery of the elastic element, thereby improving the alignment accuracy and sealing consistency between the lid and the drawer opening.

[0032] In some embodiments of this application, the housing includes a box liner and a guide structure;

[0033] The inner liner has two opposing sidewalls along its width.

[0034] The guide structure is disposed on the biliary sidewall; the side of the guide structure opposite to the corresponding biliary sidewall forms at least a portion of the compartment sidewall and is constructed with a guide rail.

[0035] The elastic element is connected to the guide structure.

[0036] This configuration unifies the installation relationship between the guide rail and the elastic element on the same load-bearing datum as the guide structure. Compared with the implementation method where the elastic element is constructed on the side wall of the drawer, this embodiment reduces the positional displacement of the elastic element caused by the installation tolerance of the drawer, deformation of the side wall of the drawer, or local deviation of the guide rail. It improves the stability of the guiding constraint from the elastic element on the mating parts during the closing process, making it easier for the lid to maintain an aligned state at the drawer opening and to seal the drawer opening.

[0037] In some embodiments of this application, the elastic element and the guide structure are integrally formed.

[0038] This design eliminates the independent assembly interface between the elastic element and the guide structure. Therefore, the installation position, pre-tightening direction, and working stroke of the elastic element can be precisely controlled during the manufacturing stage. During the closing process, the working state will not be changed due to loose fasteners, part movement, or relative displacement. While ensuring the smooth guidance of the guide rail to the mating parts, it improves the overall structural integrity, the fitting accuracy of the elastic element and the mating parts, and the working reliability, thereby improving the alignment accuracy of the cover and the storage drawer.

[0039] In some embodiments of this application, the storage drawer is slidably disposed on the guide structure.

[0040] With this configuration, the lid and the storage drawer slide relative to the same reference (guide structure). Compared to the implementation method where one of the lid and the storage drawer slides on the guide structure and the other slides on the inner wall, the embodiment of this application reduces the relative fit error between the lid and the storage drawer caused by the installation tolerance of the inner box, deformation of the inner wall, or local deviation of the guide rail. This improves the accuracy of the alignment between the lid and the storage drawer, and thus improves the sealing effect of the lid on the drawer opening when the storage drawer is closed.

[0041] In some embodiments of this application, the guide rail is a guide groove, which is recessed to the side away from the refrigeration compartment; the bottom and opening of the guide groove are opposite to each other along the width direction of the cabinet.

[0042] The elastic element is located at the bottom of the guide groove.

[0043] With this configuration, the lower sidewall can support the mating parts and guide their movement trajectory.

[0044] The upper sidewall can limit the upward movement of the mating parts, reduce the possibility of the mating parts moving upward out of the guide groove, and improve the reliability of the sliding fit between the mating parts and the guide rail. Attached Figure Description

[0066] To make the objectives and implementation methods of this application clearer, the exemplary implementation methods of this application will be clearly and completely described below with reference to the accompanying drawings of the exemplary embodiments of this application. Obviously, the exemplary embodiments described are only some embodiments of this application, and not all embodiments.

[0067] It should be noted that the brief descriptions of terms in this application are only for the convenience of understanding the embodiments described below, and are not intended to limit the embodiments of this application. Unless otherwise stated, these terms should be understood in their ordinary and common meaning.

[0068] The terms "first," "second," "third," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar or related objects or entities, and do not necessarily imply a specific order or sequence, unless otherwise specified. It should be understood that such terms are interchangeable where appropriate.

[0069] The terms “comprising” and “having”, and any variations thereof, are intended to cover but not exclude inclusion, for example, a product or device that includes a range of components is not necessarily limited to all of the components that are clearly listed, but may include other components that are not clearly listed or that are inherent to such product or device.

[0070] As stated in the background section, in refrigerators of the related art, when the storage drawer is closed, the lid has a large degree of lateral misalignment relative to the drawer. The inventors have discovered that the reason for this problem is that, in order to improve the smoothness of the lid's movement relative to the cabinet, the guide rail on the cabinet used to slide with the lid has a gap in the lateral direction between it and the sliding part of the lid. The existence of this gap leads to a large degree of lateral misalignment between the lid and the storage drawer when the drawer is closed. The misalignment between the lid and the storage drawer makes it difficult for the lid to seal the drawer.

[0071] To address the aforementioned technical problems, this application provides a refrigerator with an elastic element installed inside the guide rail. When the storage drawer is closed, the elastic element is located outside the mating part of the cover that engages with the guide rail, and it elastically presses against the mating part to reduce the lateral freedom of the cover. When the storage drawer is closed, this reduces the degree of lateral misalignment between the cover and the drawer, improving the lateral alignment accuracy between the cover and the drawer, and thus enhancing the sealing effect of the cover on the drawer opening.

[0072] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and 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.

[0073] refer to Figure 1 and Figure 2 The refrigerator provided in this application embodiment may include a cabinet 10 having a cooling compartment 101, a storage drawer 20 that can be pulled out of the cooling compartment 101, and a refrigeration system disposed in the cabinet 10 for providing cold air to the cooling compartment 101.

[0074] An opening may be formed on the front side of the refrigeration chamber 101, and the opening is connected to the refrigeration chamber 101.

[0075] It should be noted that, in the embodiments of this application, "front side" refers to the side of the refrigerator facing the user when it is in normal use, that is, along... Figure 1 The positive direction of the depth Y direction of the middle cabinet 10 is the front; "rear side" refers to the side opposite to the front, that is, the side facing away from the user when the refrigerator is in normal use, which is along the... Figure 1 The negative direction of the depth direction Y of the middle box 10 is the rear.

[0076] It is understood that the number of refrigeration compartments 101 can be one, two, or more than three. Refrigeration compartments 101 can be configured as refrigerators, freezers, or variable temperature compartments with internal temperature variations.

[0077] refer to Figure 1 The housing 10 may include a liner 11 and a shell 12. The shell 12 is attached to the outside of the liner 11 to form the appearance of the housing 10. The liner 11 may be configured to form a refrigeration compartment 101 and an opening on the front side of the refrigeration compartment 101.

[0078] In a configuration where there are multiple refrigeration rooms 101, at least some of the refrigeration rooms 101 may be equipped with storage drawers 20.

[0079] refer to Figure 2 The storage drawer 20 is pull-out along the depth direction Y of the cabinet 10 in the refrigeration compartment 101. The top of the storage drawer 20 has a drawer opening 21, which communicates with the inner cavity of the storage drawer 20. When the storage drawer 20 is pulled out, items can be placed into or taken out of the storage drawer 20 through the drawer opening 21.

[0080] refer to Figure 2 and Figure 3 The refrigerator in this embodiment of the application also includes a cover 30, which is disposed in the refrigeration compartment 101 and located on top of the storage drawer 20. The cover 30 is configured to open or close the drawer opening 21.

[0081] refer to Figure 1 When the storage drawer 20 is closed, the lid 30 closes onto the drawer opening 21.

[0082] refer to Figure 2 When the storage drawer 20 is in the open state, the cover 30 opens at least a portion of the drawer opening 21 to facilitate taking items out of or placing items into the storage drawer 20.

[0083] In some possible implementations of the embodiments of this application, a sealing strip may be provided at the bottom of the cover 30. When the storage drawer 20 is in the closed state, the sealing strip undergoes elastic deformation and fits against the top of the storage drawer 20 to seal the gap between the storage drawer 20 and the cover 30, thereby improving the sealing effect of the cover 30 on the storage drawer 20.

[0084] refer to Figure 3 In this embodiment of the refrigerator, guide rails 131 can be respectively constructed on the two side walls 102 of the refrigeration compartment 101 that are opposite each other in the width direction X.

[0085] refer to Figure 3 In the embodiment where the cabinet 10 includes a cabinet liner 11, the cabinet liner 11 can enclose and form a refrigeration chamber 101. The cabinet liner 11 can have two side walls 111 that are opposite to each other and spaced apart along the width direction X of the cabinet liner 11.

[0086] The guide rail 131 can be directly constructed on the side wall 111 of the refrigerator to reduce the structural complexity of the refrigerator.

[0087] In some other possible implementations of the embodiments of this application, reference is made to Figure 3 The housing 10 may also include a guide structure 13, which is fixedly disposed on the side wall 111 of the refrigeration chamber. For example, the guide structure 13 may be connected to the side of the side wall 111 of the refrigeration chamber facing the refrigeration compartment 101 by means of fastening bolts, snap-fit, or adhesive.

[0088] The side of the guide structure 13 opposite to the gallbladder sidewall 111 forms at least a portion of the compartment sidewall 102, and the side of the guide structure 13 opposite to the gallbladder sidewall 111 is provided with a guide rail 131.

[0089] By incorporating the guide rail 131 into the guide structure 13, the structural complexity of the box liner 11 is reduced, the structure of the box liner 11 is simplified, and the processing and manufacturing efficiency of the box liner 11 is improved.

[0090] refer to Figure 3 The cover 30 can be provided with mating parts 31 at both ends along the width direction X. The mating parts 31 are provided in a one-to-one correspondence with the guide rails 131, and the mating parts 31 can be relatively displaced along the corresponding guide rails 131.

[0091] In some possible implementations of the embodiments of this application, the mating part 31 can be a slide rod, the axis of which can extend along the width direction X of the box 10. The slide rod is slidably disposed on the guide rail 131 so that the cover 30 can slide relative to the box 10 along the guide rail 131.

[0092] In some other possible implementations of the embodiments of this application, reference is made to Figure 3 The mating part 31 can be a roller. The axis of the roller extends along the width direction X of the box 10. The roller is rotatably connected to the cover 30. The roller and the guide rail 131 are in rolling engagement to reduce the friction when the roller moves relative to the guide rail 131 and improve the smoothness of the cover 30 moving relative to the box 10.

[0093] In some possible implementations of the embodiments of this application, reference is made to Figure 4 The guide rail 131 may include a lifting rail 1312, which may extend upward from back to front at an angle.

[0094] When the storage drawer 20 is closed, the lid 30 closes onto the drawer opening 21, and the mating part 31 moves to the rear end of the lifting rail 1312. As the storage drawer 20 is pulled forward from the closed position, the mating part 31 moves forward and upward along the lifting rail 1312, thereby causing the lid 30 to move upward and forward, gradually separating it from the storage drawer 20. When the mating part 31 moves to the front end of the lifting rail 1312, the lid 30 cannot move further forward due to the stop at the front end of the lifting rail 1312. When the storage drawer 20 is pulled forward further, only the drawer 20 is pulled out, increasing the exposed drawer opening 21 for easier access to items.

[0095] In some other possible implementations of this application, the refrigerator may also include a vacuum pump, which is used to draw air out of the storage drawer 20 when the storage drawer 20 is closed, so as to create a vacuum or low-pressure environment in the storage drawer 20, thereby extending the shelf life of the food in the storage drawer 20.

[0096] The refrigerator may also include a pressure relief structure for relieving pressure on the storage drawer 20 so that the air pressure inside the storage drawer 20 is approximately balanced with the air pressure inside the cooling compartment 101.

[0097] In some embodiments, reference Figure 4 The guide rail 131 may also include a forward rail 1311, which extends along the depth direction Y of the housing 10. The rear end of the lifting rail 1312 is connected to the front end of the forward rail 1311, and the end of the lifting rail 1312 away from the forward rail 1311 extends upward at an angle.

[0098] When the storage drawer 20 is closed, the mating part 31 moves to the end of the forward slide rail 1311 away from the lifting rail 1312.

[0099] When the storage drawer 20 is partially pulled out and the pressure relief of the storage drawer 20 is completed, the mating part 31 moves to one end of the lifting rail 1312 near the front rail 1311.

[0100] When the storage drawer 20 is in the open position, the mating part 31 moves to the end of the lifting rail 1312 away from the forward rail 1311.

[0101] When the storage drawer 20 is closed, since the storage drawer 20 is not depressurized, the storage drawer 20 is in a low-pressure environment. The cover 30 is attracted to the top of the storage drawer 20 and closes the drawer opening 21.

[0102] As the storage drawer 20 is gradually pulled out from the closed state, before the internal depressurization of the storage drawer 20 is completed, the cover 30 is attracted to the storage drawer 20. The cover 30 is pulled out synchronously with the storage drawer 20, and the mating part 31 moves forward along the horizontal forward rail 1311 to guide the forward movement of the cover 30.

[0103] After the pressure inside the storage drawer 20 is released, the mating part 31 moves forward to the front end of the forward sliding rail 1311. Since the storage drawer 20 has been depressurized, the lid 30 no longer engages with the storage drawer 20. Continuing to pull the storage drawer 20 forward, the mating part 31 moves forward and upward along the lifting rail 1312, thereby causing the lid 30 to move upward and forward, gradually separating it from the storage drawer 20. When the mating part 31 moves to the front end of the lifting rail 1312, the lid 30 cannot move forward further due to the stop at the front end of the lifting rail 1312. Continuing to pull the storage drawer 20 forward, only the storage drawer 20 will be pulled out (see reference). Figure 2 This increases the exposed drawer opening 21, making it easier to take out and put in items.

[0104] The refrigerator of this application embodiment refers to... Figure 3 An elastic element 14 is also constructed on the side wall 102 of the compartment. The elastic element 14 can be a sheet-like elastic arm, a bent arm, an arc-shaped pressure arm, or a partially protruding elastic tongue, etc. At least a portion of the elastic element 14 extends into the guide rail 131. At least a portion of the plurality of guide rails 131 of the housing 10 can be correspondingly arranged with the elastic element 14.

[0105] In the implementation where the guide rail 131 is constructed on the gallbladder sidewall 111, the elastic element 14 is connected to the gallbladder sidewall 111.

[0106] In the implementation where the guide rail 131 is constructed on the guide structure 13, the elastic element 14 can be connected to the guide structure 13 (see reference). Figure 4 (or gallbladder sidewall 111.)

[0107] refer to Figure 5 , Figure 6 and Figure 7When the storage drawer 20 is closed, the elastic element 14 is located on the outside of the mating element 31 along the width direction X of the box body 10, and is elastically pressed and engaged with the mating element 31. Since the pressing force of the elastic element 14 on the mating element 31 acts on the outside of the mating element 31 along the width direction X of the box body 10, it can guide the cover 30 laterally (that is, the width direction X of the box body 10), so that it gradually corrects the lateral deviation and stably falls into the predetermined closed position when it approaches the drawer opening 21. When the storage drawer 20 is closed, it reduces the degree of misalignment of the cover 30 relative to the storage drawer 20 in the lateral direction, improves the alignment accuracy of the cover 30 and the storage drawer 20 in the lateral direction, and thus improves the sealing effect of the cover 30 on the drawer opening 21.

[0108] As the storage drawer 20 is gradually pulled out from the closed state, the mating parts 31 at both ends of the lid 30 move along the guide rail 131, and the lid 30 moves away from above the drawer opening 21. When the storage drawer 20 is pushed back and enters the closed state, the lid 30 gradually returns to its original position under the constraint of the guide rail 131. The mating parts 31 move along the guide rail 131 into the section near the closed position. The elastic element 14 gradually contacts the mating parts 31 and undergoes elastic deformation because it extends at least partially into the guide rail 131. Under the action of this elastic restoring force, the mating parts 31 are laterally corrected along the width direction X of the cabinet 10, so that the lid 30 is pushed to the predetermined alignment position and remains stably fitted when it approaches the final closed position, until the lid 30 closes the drawer opening 21 and forms a relatively closed space with the storage drawer 20.

[0109] Since the guide rail 131 limits the movement path of the cover 30, the elastic element 14 applies a compression fit to the mating element 31 at the closing end. The lateral offset and wobbling of the cover 30 at the closing end point can be limited to a small range. Therefore, the correspondence between the cover 30 and the drawer opening 21 is more stable, and the contact state of the sealing boundary can be kept consistent, which helps to improve the sealing stability at the drawer opening 21.

[0110] Furthermore, during the gradual opening of the storage drawer 20 from the closed state, the elastic element 14 only engages in contact with the mating element 31 in a local section. After the mating element 31 leaves, the elastic element 14 returns to its original position, reducing the impact on the normal sliding of the cover 30 along the guide rail 131. This achieves a coordinated operation between smooth opening and closing and end positioning and pressing.

[0111] refer to Figure 7In the implementation of the guide rail 131, which includes a forward sliding rail 1311 and a lifting rail 1312, the elastic element 14 is disposed within the forward sliding rail 1311. When the storage drawer 20 is in the closed state, the mating part 31 moves to the end of the forward sliding rail 1311 away from the lifting rail 1312 and elastically presses against the elastic element 14. This allows the mating part 31 to be guided to a more stable fitting position by the elastic recovery effect of the elastic element 14 when it moves to the end of the forward sliding rail 1311 away from the lifting rail 1312, thereby improving the alignment accuracy and sealing consistency between the lid 30 and the drawer opening 21.

[0112] refer to Figure 4 In the implementation of the housing 10 including the guide structure 13, the elastic element 14 is connected to the guide structure 13, so that the elastic element 14 and the guide rail 131 are both integrated on the guide structure 13. The installation relationship of the guide rail 131 and the elastic element 14 is unified on the same bearing reference of the guide structure 13. Compared with the implementation where the elastic element 14 is constructed on the inner wall 111, this embodiment reduces the positional displacement of the elastic element 14 caused by the installation tolerance of the inner wall 11, the deformation of the inner wall 111, or the local deviation of the guide rail 131. It improves the stability of the guiding constraint from the elastic element 14 on the mating part 31 during the closing process, and makes it easier for the cover 30 to maintain the alignment at the drawer opening 21 and seal the drawer opening 21.

[0113] refer to Figure 4 and Figure 8 The elastic element 14 can be integrally formed with the guide structure 13. For example, the elastic element 14 and the guide structure 13 can be formed in one step by injection molding, stamping bending or overmolding, so that there is no independent assembly interface between the elastic element 14 and the guide structure 13. Therefore, the installation position, pre-tightening direction and working stroke of the elastic element 14 can be precisely controlled during the manufacturing stage. During the closing process, the working state will not be changed due to loose fasteners, movement of parts or relative displacement. While ensuring the smooth guidance of the guide rail 131 to the mating part 31, the overall structure, the fitting accuracy of the elastic element 14 and the mating part 31 and the working reliability are improved, thereby improving the alignment accuracy of the cover 30 and the storage drawer 20.

[0114] In some possible implementations of the embodiments of this application, reference is made to Figure 2 and Figure 3The storage drawer 20 is slidably mounted on the guide structure 13. Since the cover 30 also slides relative to the guide structure 13, the cover 30 and the storage drawer 20 slide relative to the same reference (guide structure 13). Compared to the implementation method where one of the cover 30 and the storage drawer 20 is slidably mounted on the guide structure 13 and the other is slidably mounted on the inner wall 111, the embodiment of this application reduces the relative fitting error between the cover 30 and the storage drawer 20 caused by the installation tolerance of the inner wall 11, the deformation of the inner wall 111, or the local deviation of the guide rail 131. This improves the accuracy of the alignment between the cover 30 and the storage drawer 20, thereby improving the sealing effect of the cover 30 on the drawer opening 21 when the storage drawer 20 is in the closed state.

[0115] In some possible implementations of the embodiments of this application, reference is made to Figure 4 and Figure 8 The guide rail 131 can be a guide groove, which can be recessed along the width direction X of the cabinet 10 towards the side opposite to the refrigeration chamber 101. The bottom 132 and the opening 133 of the guide groove are opposite each other along the width direction X of the cabinet 10. The opening 133 of the guide groove is closer to the refrigeration chamber 101 than the bottom 132 of the guide groove.

[0116] The elastic element 14 can be disposed at the bottom 132 of the guide groove.

[0117] refer to Figure 8 The guide groove may have an upper sidewall 134 and a lower sidewall 135 that are opposite to and spaced apart along the height direction Z of the housing 10, with the upper sidewall 134 located above the lower sidewall 135.

[0118] The lower sidewall 135 can support the mating part 31 and guide the movement trajectory of the mating part 31.

[0119] The upper sidewall 134 can limit the upward movement of the mating part 31, reduce the possibility of the mating part 31 moving upward out of the guide groove, and improve the reliability of the sliding fit between the mating part 31 and the guide rail 131.

[0120] In some possible implementations of the embodiments of this application, reference is made to Figure 7 and Figure 8 The elastic element 14 can be an elastic arm, which can be plate-shaped or rod-shaped, etc. (See reference) Figure 9 , Figure 10 and Figure 11 The two ends of the elastic arm extending in the direction of extension have a fixed end 141 and a movable end 142, respectively.

[0121] The fixed end 141 is connected to the side wall 102 of the compartment, and the movable end 142 extends obliquely toward the cover 30 into the guide rail 131. Under the compression of the mating part 31, the movable end 142 can move elastically relative to the fixed end 141 along the width direction X of the box 10.

[0122] The movable end 142 can be located in any position of the fixed end 141. For example, the movable end 142 can be located directly below, diagonally below, directly above, diagonally above, directly in front of, diagonally in front of, directly behind or diagonally behind the fixed end 141, as long as the movable end 142 can elastically move relative to the fixed end 141 along the width direction X of the box 10 under the compression of the mating part 31.

[0123] refer to Figure 7 When the storage drawer 20 is closed, the movable end 142 or the part of the elastic arm near the movable end 142 is elastically pressed and engaged with the mating part 31.

[0124] When the storage drawer 20 is in the closed state, in the way that the movable end 142 and the mating part 31 are elastically squeezed together, the elastic arm and the mating part 31 are in line contact. When the storage drawer 20 is gradually pulled out from the closed state, the frictional force from the elastic arm on the mating part 31 is small, and the storage drawer 20 is pulled out with less effort.

[0125] When the storage drawer 20 is closed, in the way that the part of the elastic arm near the movable end 142 is elastically pressed and engaged with the mating part 31, the elastic arm and the mating part 31 are in surface contact. The large contact area between the elastic arm and the mating part 31 increases the stability of the interaction force between the elastic arm and the mating part 31.

[0126] During the relative displacement of the mating part 31 along the guide rail 131, the movable end 142 or the elastic arm near the movable end 142 undergoes elastic bending or slight rebound after being compressed, thereby generating a lateral preload force on the mating part 31 along the width direction X of the housing 10, and using this preload force to compensate for the positional offset caused by manufacturing tolerances, assembly deviations and guide clearances.

[0127] Since the elastic arm provides limiting and return capabilities to the mating part 31 by relying on its own elastic recovery, it can still maintain stable contact pressure and guiding effect after multiple opening and closing cycles, which helps to improve the alignment accuracy, sealing reliability and vacuum retention capability of the storage drawer 20 in the closed state.

[0128] In some possible implementations of the embodiments of this application, reference is made to Figure 7The movable end 142 can be located on the side of the fixed end 141 opposite to the pull-out direction of the storage drawer 20, that is, the movable end 142 is located behind the fixed end 141, so that the elastic arm facing the cover 30 forms a guide surface inclined towards the refrigeration compartment 101 along the depth direction Y of the cabinet 10. During the process of the storage drawer 20 gradually closing from the open state, this guide surface can guide the mating part 31, so that the mating part 31 gradually slides into the area of ​​the movable end 142 along the guide surface, and elastically presses against the elastic arm at the movable end 142, reducing the possibility of interference and jamming between the mating part 31 and the elastic arm, and improving the stability of the cover 30 during movement.

[0129] Furthermore, as the lid 30 approaches the closed position, the elastic arm gradually engages in the lateral compression of the mating part 31, with the compression force gradually increasing. The mating part 31 does not need to continuously overcome a large resistance force from the elastic arm during its forward movement in the pull-out direction. Therefore, the sliding resistance of the lid 30 when the storage drawer 20 is opened is smaller, and the guiding action is smoother.

[0130] In some embodiments, reference Figure 7 , Figure 8 and Figure 11 The elastic arm may include an inclined section 143 and a clamping section 144 connected to each other.

[0131] The end of the inclined section 143 away from the clamping section 144 is the fixed end 141; the inclined section 143 extends inclinedly relative to the depth direction Y of the box 10, and the end of the inclined section 143 away from the fixed end 141 is closer to the cover 30 than the fixed end 141.

[0132] The clamping section 144 is located inside the guide rail 131, and the end of the clamping section 144 away from the tilting section 143 is the movable end 142.

[0133] The clamping section 144 extends along the depth direction Y of the housing 10. (Reference) Figure 7 When the storage drawer 20 is closed, the clamping section 144 and the mating part 31 are elastically pressed together.

[0134] The inclined section 143 allows the mating part 31 to enter the predetermined position along a gradually transitioning force path during the closing of the storage drawer 20. The clamping section 144, extending along the depth direction Y of the box body 10, facilitates the formation of a more stable line contact or surface contact, thereby improving the continuous pressing and limiting effect of the elastic arm on the mating part 31.

[0135] As the storage drawer 20 gradually closes from the open state, the mating parts 31 at both ends of the lid 30, upon contacting the elastic arm, first converge towards the predetermined closing trajectory under the guidance of the inclined section 143. Since the inclined section 143 is arranged at an angle relative to the depth direction Y of the cabinet 10, its end away from the fixed end 141 is closer to the lid 30. Therefore, the mating parts 31 will first contact the inclined section 143 and obtain lateral guiding force when approaching the closing end, thereby gradually eliminating the lateral offset caused by manufacturing tolerances, installation deviations, and movement clearances.

[0136] As the storage drawer 20 continues to close, the mating part 31 gradually undergoes elastic compression with the clamping section 144. Under the action of its own elastic restoring force, the clamping section 144 applies a stable clamping constraint to the mating part 31, so that the cover 30 obtains a more accurate centering position and a more reliable end positioning near the drawer opening 21.

[0137] Since the inclined section 143 and the clamping section 144 form a continuous transition structure of first introducing and then clamping, the possibility of sudden collision or jumping of the mating part 31 at the closed end is reduced. Instead, the position correction and force stabilization are completed in a gradual manner. Therefore, the lateral stability of the cover 30 in the closed state can be improved, the shaking and deviation can be reduced, and the sealing accuracy between the cover 30 and the drawer opening 21 can be improved.

[0138] In some possible implementations of the embodiments of this application, reference is made to Figure 7 and Figure 12 The compartment sidewall 102 located on the side of the guide rail 131 away from the cover 30 may be provided with a clearance opening 103, which is configured to allow the movable end 142 to pass through.

[0139] In the implementation where the guide rail 131 is constructed on the gallbladder sidewall 111, the clearance opening 103 can be constructed on the gallbladder sidewall 111.

[0140] refer to Figure 12 In the implementation of the guide rail 131 being constructed on the guide structure 13, the clearance opening 103 can be constructed on the guide structure 13 to reduce the possibility of cold leakage in the refrigeration compartment 101 caused by constructing an opening on the side wall 111 of the bladder, thereby reducing the insulation performance.

[0141] The fixed end 141 is connected to the edge of the clearance opening 103. The fixed end 141 is connected to the edge of the clearance opening 103, that is, the root of the elastic arm is connected to the periphery of the clearance opening 103 by means of welding, screw fixing, snap-fitting, riveting or integral molding, so as to form a stable support base.

[0142] The projection of the elastic arm on the side wall 102 of the compartment is located within the clearance opening 103, so that the movable end 142 can enter or pass through the space corresponding to the clearance opening 103 when it is under pressure.

[0143] When the movable end 142 passes through the clearance opening 103, a necessary gap can be maintained between the edge of the clearance opening 103 and the movable end 142 to avoid scratching, jamming or local fatigue wear, thereby improving the reliability of long-term use.

[0144] The clearance opening 103 is a clearance opening provided on the side wall 102 of the compartment, which is used to provide passage space for the movable end 142 of the elastic arm and form a local deformation area, so that the elastic arm can obtain sufficient elastic displacement without increasing the overall installation space occupied.
