[0002] Due to space constraints, existing refrigerators typically have multiple drawers divided into freezer and refrigerator compartments to maximize internal space. Each drawer has a cover that closes or seals the drawer. However, when the cover is fixed, the drawer's movement can cause friction against the lower surface of the cover, affecting the seal. Summary of the Invention

[0003] The main objective of this invention is to provide a refrigerator that addresses the problem in the prior art where the process of pulling out the drawers causes scratches against the lower surface of the cover, affecting the sealing effect.

[0004] To achieve the above objectives, the present invention provides a refrigerator, comprising:

[0005] The shell has a cavity;

[0006] A cover plate assembly, disposed within the cavity, includes a mounting member, a cover plate, and a connecting member. The mounting member is connected to the housing, and the cover plate is positioned below the mounting member. One end of the connecting member is hinged to the mounting member, and the other end is hinged to the cover plate, allowing the cover plate to swing up and down relative to the mounting member. The connecting member and the mounting member are elastically connected.

[0007] A drawer is slidably installed within the cavity and located below the cover; when the drawer is pushed into the cavity, the drawer pushes the cover to swing downward so that the cover covers the drawer; when the drawer is pulled out, the cover separates from the drawer and swings upward to avoid the drawer.

[0008] In one embodiment, the cover plate assembly includes an elastic element, the upper end of which is connected to the mounting member, and the lower end of which is connected to the connector, for pulling the connector to swing upward.

[0034] This invention proposes a refrigerator, with reference to Figures 1 to 7 The refrigerator includes a shell, a cover assembly, and a drawer 11. The shell has a cavity 10. The cover assembly is disposed within the cavity and includes a mounting member 60, a cover plate 20, and a connector 40. The mounting member 60 is disposed within the cavity 10. The cover plate 20 is disposed below the mounting member 60. One end of the connector 40 is hinged to the mounting member 60, and the other end is hinged to the cover plate 20, so that the cover plate 20 can swing up and down relative to the mounting member 60. The connector 40 and the mounting member 60 are elastically connected. The drawer 11 is slidably installed within the cavity 10 and is located below the cover plate 20. When the drawer 11 is pushed into the cavity 10, the drawer 11 pushes the cover plate 20 to swing downward so that the cover plate 20 covers the drawer 11. When the drawer 11 is pulled out, the cover plate 20 separates from the drawer 11 and swings upward to avoid the drawer 11.

[0035] In this embodiment, a refrigerator door is provided with an opening on one side of the housing, forming a cavity 10 inside the housing. The mounting member 60 is a partition fixedly installed within the cavity 10, dividing the cavity 10 into multiple storage areas. A guide rail 13 is provided on the inner wall of the cavity 10, and rollers 12 adapted to the guide rail 13 are provided on the left and right sides of the drawer 11, allowing the drawer 11 to be pushed and pulled inside the cavity 10. The connecting member 40 is hinged to the mounting members 60 at the upper and lower ends and the cover plate 20, respectively, to form a four-bar linkage. Preferably, the four-bar linkage is a parallelogram mechanism. The cover plate 20 can swing up and down together with the connecting member 40. During the swinging process, the included angle between the cover plate 20 and the mounting member 60 remains constant, and the plane containing the upper opening edge of the drawer 11 remains parallel to the cover plate 20.

[0036] In addition, in the above-mentioned four-bar linkage, the front and rear connecting parts 40 can be set to different lengths. The connecting part 40 located near the inside of the cavity 10 or away from the door is the first connecting part 40, and the connecting part 40 located near the handle of the drawer 11 is the second connecting part 40. When the drawer 11 is pulled out, as long as the cover plate 20 can be moved up and avoid the drawer 11, the specific length of the two connecting parts 40 can be calculated and is not further limited here.

[0037] Regarding the elastic connection between the connector 40 and the mounting piece 60, a spring connection can be used. One end of the spring is attached to the mounting piece 60, and the other end is attached to the connector 40. The tension of the spring provides the elastic force to overcome the weight of the connector 40 and the cover plate 20 and pull them upwards. Alternatively, a torsion spring can be installed at the hinge point between the connector 40 and the mounting piece 60. The two ends of the torsion spring are connected to the mounting piece 60 and the connector 40 respectively, and the torsion force of the torsion spring drives the connector 40 to swing upwards.

[0038] In this embodiment, the end of the cover plate 20 away from the door extends downwards. When the drawer 11 is pushed into the cavity 10, the side of the drawer 11 away from the door abuts against the downwardly extending part of the cover plate 20, which can push the cover plate 20 to swing downwards. The swinging process can be decomposed into movement into the cavity 10 and vertical downward movement. When the drawer 11 is fully pushed into the cavity 10, the upper cover plate 20 just covers the opening of the drawer 11. At this time, the static friction force of the drawer 11 is greater than or equal to the component force of the elastic element 50 relative to the static friction force. When the drawer 11 is pulled out, the external pulling force and the component force of the elastic element 50 are greater than the above-mentioned static friction force, thereby the cover plate 20 automatically swings upwards and separates from the drawer 11.

[0039] This invention provides a cover plate 20 above the drawer 11, along with a connector 40 and a mounting member 60. The cover plate 20 and the connector 40 form a four-bar linkage. When the drawer 11 is pushed into the cavity 10, the cover plate 20 moves diagonally downward with the connector 40. When the drawer 11 is fully pushed into the cavity 10, the cover plate 20 covers the upper opening of the drawer 11. When the drawer 11 is pulled out of the cavity 10, the cover plate 20 moves diagonally upward with the connector 40 and separates from the drawer 11. The connector 40 and the mounting member 60 are elastically connected by an elastic member 50. During the above movement, the elastic member 50 provides a driving force to swing the push rod upward, preventing scratching between the drawer 11 and the cover plate 20, and ensuring the sealing of the cover plate 20 and the drawer 11.

[0040] In one embodiment, reference is made to Figures 1 to 7 The cover plate 20 assembly includes an elastic element 50. The upper end of the elastic element 50 is connected to the mounting member 60, and the lower end of the elastic element 50 is connected to the connecting member 40, for pulling the connecting member 40 to swing upward. The connecting member 40 is provided with an upward-facing groove 43, and a connecting portion 44 is provided in the groove 43. The elastic element 50 is located in the groove 43 and connected to the connecting portion 44. In this embodiment, the elastic element 50 is preferably a tension spring. The lower end of the connecting member 40 is provided with a first hinge shaft 41, the upper end is provided with a groove 43, and second hinge shafts 42 are provided on both sides of the groove 43. Thus, the upper end of the connecting member 40 forms a fork-shaped structure, and the two second hinge shafts 42 are respectively located on both sides of the groove 43 and are coaxially arranged. The spring is arranged between the two second hinge shafts 42 to achieve balanced force. The first hinge shaft 41 is located at the lower end of the connecting member 40 away from the groove 43 and is arranged on the same side as one of the hinge shafts. By setting the groove 43, the tension spring can be installed in the groove 43 and is in a semi-closed state, which can play a certain protective role for the tension spring and avoid failure caused by interference from external debris or other structures.

[0041] In one embodiment, reference is made to Figures 1 to 7The upper end of the connector 40 is provided with a second hinge shaft 42 located on both sides of the groove 43. The mounting member 60 is provided with a second hinge seat, and the second hinge seat is provided with a second shaft hole for mounting the second hinge shaft 42. The upper end of the elastic member 50 is connected to the second hinge seat. In this embodiment, the fixing point of the upper end of the spring should be located on one side of the second hinge shaft 42, so that the spring and the connector 40 can maintain a certain angle. The spring tension and the component of the force perpendicular to the connector 40 provide the driving force to drive the connector 40 to swing upward. Specifically, to match the structure of the connector 40, the second hinge seat includes a base plate fixedly disposed on the lower surface of the mounting member 60 and two mounting plates disposed on the lower surface of the base plate and disposed opposite to each other. The second shaft hole is disposed on the mounting plate, and the connector 40 is disposed between the two mounting plates. A hanging hole or pin is also provided on the base plate above the second shaft hole, and the upper end of the spring is disposed on the hanging hole or pin. When drawer 11 is fully pushed into cavity 10 and connector 40 remains vertical, the direction of spring tension coincides with the line connecting the upper and lower hinge points of connector 40, and cover 20 is in a self-locking state.

[0042] In one embodiment, reference is made to Figures 1 to 7 The lower end of the connector 40 is provided with a first hinge shaft 41, and the cover plate 20 is provided with a first hinge seat 2121. The first hinge seat 2121 is provided with a first shaft hole corresponding to the first hinge shaft 41, and the first hinge shaft 41 can move up and down within the first shaft hole. In this embodiment, the first hinge seat 2121 is provided on the upper surface of the cover plate 20, and the first shaft hole is a vertically arranged strip hole or elliptical hole. There is space in the first shaft hole for the first hinge shaft 41 to move, which facilitates the assembly between the connector 40 and the cover plate 20, and can also compensate for dimensional deviations between components. When the drawer 11 is pushed into the cavity 10, even if the connector 40 exerts a certain downward pressure on the drawer 11 through the cover plate 20, it can be compensated by the aforementioned movable space to prevent the connector 40 from blocking the cover plate 20.

[0043] In one embodiment, reference is made to Figures 1 to 7The lower end of the connector 40 is provided with a downwardly extending mounting portion 46, and an elastic abutment 45 is provided on the mounting portion 46, which abuts against the cover plate 20. In this embodiment, since the first shaft hole has a certain amount of room for movement, when the drawer 11 is fully closed, the first hinge shaft 41 is located in the middle area inside the first shaft hole. At this time, it does not exert pressure on the cover plate 20, and relies entirely on the weight of the cover plate 20 to cover the upper opening of the drawer 11. The pressure is small and does not affect the sealing effect. By setting the elastic abutment 45, the downward pressure of the connector 40 can be transmitted to the cover plate 20 to improve the sealing performance. Specifically, a compression spring can be sleeved on the mounting portion 46, with one end of the compression spring abutting against the cover plate 20 to ensure that the first hinge shaft 41 is located in the upper area inside the first shaft hole. By setting the first shaft hole and the first hinge shaft 41 in a clearance fit structure, and by using a compression spring to position the first hinge shaft 41 in the upper region inside the first shaft hole, the clearance between the shaft hole and the hinge shaft can accommodate the tolerances in the structure or assembly, and the compression spring can also provide a certain pressure to the cover plate 20.

[0044] In one embodiment, reference is made to Figures 1 to 7 The elastic abutment 45 is a spring sheet, which is disposed at the lower end of the mounting portion 46, and a deformation gap is formed between the spring sheet and the connecting member 40. In this embodiment, the elastic abutment 45 can be configured as a spring sheet in addition to the compression spring described above. The connecting member 40, the mounting portion 46, and the elastic abutment 45 can be integrally injection molded. One end of the spring sheet is connected to the mounting portion 46, and the other end extends along a direction parallel to the first hinge axis 41. The lower surface of the spring sheet is configured as an arc surface so that the connecting member 40 remains in contact with the cover plate 20 during rotation. Even if the connecting member 40 rotates to the lowest position, causing the elastic abutment 45 to apply a certain pressure to the cover plate 20, the deformation gap can still provide deformation space for the deformation of the elastic abutment 45.

[0045] In one embodiment, reference is made to Figures 1 to 7 The number of connectors 40 is at least two, and the at least two connectors 40 are spaced apart along the length of the cover plate 20. In this embodiment, the end closer to the refrigerator door is the front side, the end extending into the cavity 10 and away from the door is the rear side, and the two sides of the drawer 11 perpendicular to the front and back directions are the left and right sides, respectively. Two connectors 40 can be provided, located on the left and right sides of the cover plate 20, with one on the front side and the other on the rear side. This solution minimizes the number of connectors 40, but it may result in uneven force distribution. Therefore, it is best to provide four connectors 40, located on the left and right sides of the cover plate 20, with one connector at each of the front and rear ends of the left and right sides. This makes the force on the cover plate 20 more balanced and the swing more stable when it swings.

[0046] In one embodiment, reference is made to Figures 1 to 7 The elastic element 50 includes a spring. When the drawer 11 is fully pushed into the cavity 10, the angle between the line connecting the hinge centers of the upper and lower ends of the connector 40 and the center line of the spring is in the range of -15° to 15°. In this embodiment, the angle is preferably kept at 0°. At this time, the spring tension cannot be decomposed into a component force that drives the connector 40 to swing. Although the spring is in a stretched state, the elastic force is along the line connecting the hinge points. Additional tension is required to drive the connector 40 to rotate. When the angle is between -15° and 15°, although the spring tension can be decomposed into a component force perpendicular to the line connecting the hinge points, the corresponding component force is also small because the angle is very small. The static friction between the drawer 11 and the shell and the lid is greater than or equal to the above component force, and the spring will not pop the drawer 11 out, thereby achieving self-locking of the drawer 11. When drawer 11 is pulled out, the static friction between it and cover plate 20 causes cover plate 20 to swing outward. When it swings to the desired angle, the spring force overcomes the weight of cover plate 20 and connector 40, lifting cover plate 20 and connector 40 to the area above drawer 11.

[0047] In one embodiment, reference is made to Figures 1 to 7 The cover plate 20 is provided with a first abutting part 14, and the drawer 11 is provided with a second abutting part 22. When the drawer 11 is pushed into the cavity 10, the second abutting part 22 abuts against the drawer 11, thereby pushing the cover plate 20 to swing downward. In this embodiment, by providing the first abutting part 14 and the second abutting part 22, the linkage between the drawer 11 and the cover plate 20 can be realized, while simultaneously preventing the upper opening of the drawer 11 from scratching the lower surface of the cover plate 20. Specifically, the first abutting part 14 and the second abutting part 22 can be provided on the rear side of the drawer 11 and the cover plate 20 or on the left and right sides to realize the linkage between the cover plate 20 and the drawer 11. The downward swing of the cover plate 20 is powered by the drawer 11, while also overcoming the tension of the spring. The upward swing of the cover plate 20 requires external force to overcome the static friction between the drawer 11 and external components in the initial stage of the movement, after which the tension of the spring can drive the cover plate 20 to swing upward.

[0048] In one embodiment, reference is made to Figures 1 to 7The cover plate 20 includes a plate body and a surrounding edge extending downward from the edge of the plate body. The first abutting portion 14 includes a first extension portion and a second extension portion. The first extension portion extends from the lower end of the surrounding edge along the drawer's pull-out direction, and the second extension portion extends downward from the first extension portion. In this embodiment, the first abutting portion 14 and the second abutting portion 22 are disposed on the rear side of the cover plate 20 and the drawer 11. Specifically, the surrounding plate extends downward and outward from the four sides of the plate body to form an outwardly flared edge. The first abutting portion 14 includes a right-angle structure disposed at the lower edge of the flared edge. The right-angle structure includes a first extension portion disposed at the lower edge of the flared edge and extending horizontally, and a second extension portion disposed at the edge of the horizontal extension portion and extending downward.

[0049] In one embodiment, reference is made to Figures 1 to 7 The second abutment portion 22 is disposed on the side wall of the drawer 11 away from the door body, located at the edge of the opening of the drawer 11's top cover, and abuts against the second extension portion. Specifically, the second abutment portion 22 also includes a horizontal extension portion extending rearward from the edge of the opening of the drawer 11's top cover, and a vertical extension portion extending downward from the free end of the horizontal extension portion. The second abutment portion 22 is also a right-angle structure and extends left and right along the upper edge of the rear side wall of the drawer 11. During the process of the drawer 11 being pushed into the cavity 10, the outer surface of the vertical extension portion fits against the inner surface of the second extension portion, making the force on the cover plate 20 more balanced, and further reducing the left and right torque caused by uneven force.

[0050] In one embodiment, reference is made to Figures 1 to 7 A buffer element, preferably a silicone pad or a rubber pad, is also provided on the upper surface of the cover plate 20. When the cover plate 20 swings to its highest position, it may collide with the connecting piece 40 above. The buffer element can buffer and limit the movement. The limiting function of the buffer element can also prevent the connecting piece 40 from swinging too much and causing the linkage mechanism to fail.

[0051] In one embodiment, reference is made to Figures 1 to 7 Ventilation holes can be provided on the cover plate 20, and a fan 30 can be installed at the ventilation holes to extract air from the drawer 11 or to expel air from the cavity 10 into the drawer 11. Specifically, the cover plate 20 can be recessed downwards in a certain area near the door to form a certain mounting position, in which the aforementioned ventilation holes are located and the fan 30 is located to avoid interference with the mounting component 60 above. In addition, since the lower surface of the cover plate 20 is protruding, the cover plate 20 is tilted inwards to avoid interference with the protruding part when the drawer 11 is pulled out horizontally.

[0052] Refrigerators are used to store food or other items, and the humidity requirements for the storage environment vary depending on the items. Fruits and vegetables require a high-humidity, low-temperature environment during storage. Therefore, the relatively sealed space between the lid and drawer 11 prevents moisture loss from the air inside drawer 11, avoiding excessive dryness that could cause the fruits and vegetables to wilt. For various dried foods that require a dry environment, it is necessary to maintain a low humidity level inside drawer 11. By using the fan 30 to extract or blow air, the humid air inside drawer 11 can be expelled, and dry, cold air from the cavity 10 can be introduced into drawer 11, maintaining a dry and cold environment inside drawer 11.

[0053] The specific operation process is as follows:

[0054] Once drawer 11 is pulled out, the fan 30 is activated after a short period of time when it is closed to the door. Moisture inside the refrigerator cavity 10 is carried away by the refrigeration unit, and simultaneously, the fan 30 draws out moisture from inside drawer 11, achieving internal dryness. If drawer 11 and the door remain closed, the fan 30 is activated periodically to complete a dehumidification process, ensuring the inside of drawer 11 remains dry.

[0055] Within the refrigerator's cavity 10, multiple drawers 11 can be installed. These drawers 11 are divided into different storage areas based on humidity requirements, specifically high-humidity drawers 11, medium-humidity drawers 11, and low-humidity drawers 11. In the high-humidity drawer 11, the fan 30 remains off. In the medium-humidity and low-humidity drawers 11, the fan 30 operates at different frequencies, with the low-humidity drawer 11 operating more frequently. For example, in the medium-humidity drawer 11, the fan 30 operates every four hours, while in the low-humidity drawer 11, the fan 30 operates every two hours.

[0056] This invention provides a cover plate 20 above the drawer 11, along with a connector 40 and a mounting member 60. The cover plate 20 and the connector 40 form a connector 40 mechanism. When the drawer 11 is pushed into the cavity 10, the cover plate 20 moves obliquely downward with the connector 40. When the drawer 11 is fully pushed into the cavity 10, the cover plate 20 covers the upper opening of the drawer 11. When the drawer 11 is pulled out of the cavity 10, the cover plate 20 moves obliquely upward with the connector 40 and separates from the drawer 11. The connector 40 and the mounting member 60 are elastically connected by an elastic member 50. During the above movement, the elastic member 50 provides a driving force to swing the push rod upward, preventing scratching between the drawer 11 and the cover plate 20, and ensuring the sealing of the cover plate 20 and the drawer 11.

[0057] The above description is merely an optional embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
