Abstract

The present invention provides a refrigerator. A transmission assembly is arranged in a storage compartment, and includes a first transmission arm and a second transmission arm arranged toward the front side of the refrigerator and capable of moving forward and backward; wherein the first transmission arm and the second transmission arm can drive each other to move in opposite directions. The linkage structure is telescopically assembled on the second door body along the thickness direction of the second door body, and is configured to be pushed by the second transmission arm to move in the direction of its retraction when the second transmission arm moves forward, and to push the second transmission arm to move backward when it moves in the direction of its extension. The cam assembly includes a cam rotatably arranged in the second door body along the vertical direction. The vertical beam body is telescopically assembled on the second door body along the transverse direction of the second door body, and cooperates with the cam assembly so that when the cam rotates in the first direction, the vertical beam body is pushed to extend from the second door body to contact the first door body; when the vertical beam body is retracted into the second door body, it drives the cam to rotate in the second direction. This prevents the vertical beam body from blocking the taking and placing of items in the compartment.

Description

Technical Field

[0001] The present invention relates to the field of refrigeration equipment, in particular to a refrigerator and a refrigerator. Background Art

[0002] Currently, refrigerator storage compartments often use a drawer-style structure. However, this structure has several drawbacks that affect the user experience. For example, the drawer-style structure limits the size of items that can be stored. Furthermore, if the refrigerator's storage compartment is used for extended periods, the drawer-style structure can easily deform, making it difficult to close securely.

[0003] To address this issue, refrigerators have storage compartments with double doors and fixed vertical beams to prevent cold air from leaking through the double doors. However, these beams also limit the size of items to be stored, preventing larger items from being stored in the compartment. This reduces the effective utilization of the compartment and impacts the user experience.

[0004] Currently, a movable vertical beam is generally installed on one of the bi-parting doors. When the bi-parting door opens the storage compartment, the movable vertical beam moves away with the bi-parting door to avoid affecting the size of the storage compartment. However, when the other bi-parting door opens the storage compartment, the movable vertical beam still blocks the access to the storage compartment. Summary of the Invention

[0005] An object of the present invention is to provide a refrigerator for solving the above technical problems.

[0006] In particular, the present invention provides a refrigerator comprising a storage compartment having an opening, a first door and a second door pivotally disposed on both lateral sides of the opening, and:

[0007] A transmission assembly is disposed in the storage compartment and includes a first transmission arm and a second transmission arm disposed toward the front of the refrigerator and capable of moving forward and backward; wherein the first transmission arm and the second transmission arm can drive each other to move in opposite directions;

[0008] a linkage structure, telescopically assembled to the second door body along the thickness direction of the second door body, configured to be pushed by the second transmission arm to move in a retracting direction thereof when the second transmission arm moves forward, and to push the second transmission arm to move backward when moving in an extending direction thereof;

[0009] A cam assembly includes a cam rotatably disposed in a vertical direction within the second door body; the cam is configured to be driven by the linkage structure to rotate in a first direction when the linkage structure moves in its retracting direction, and to drive the linkage structure to move in its extending direction when the linkage structure rotates in a second direction;

[0010] The vertical beam body is telescopically assembled on the second door body along the transverse direction of the second door body, and cooperates with the cam assembly to make the cam close the opening in the first door body, and the first door body pushes the first transmission arm to move backward. When the cam rotates along the first direction, it pushes the vertical beam body out of the second door body to resist the first door body; when the first door body opens, the vertical beam body retracts into the second door body and drives the cam to rotate along the second direction.

[0011] Optionally, the cam assembly comprises:

[0012] The accommodating groove is provided on a side of the second door body opposite to the pivot axis thereof, with its opening facing away from the pivot axis of the second door body, and is used for allowing the vertical beam body to extend from the opening or retract into the opening in the transverse direction of the second door body;

[0013] The cam is pivotally arranged on the vertical beam body and is configured to rotate from the concave part of its edge to the convex part of its edge and contact the side opposite to the accommodating groove and the opening when rotating along the first direction, and to rotate from the convex part of its edge to the concave part of its edge and contact the side opposite to the accommodating groove and the opening when rotating along the second direction.

[0014] Optionally, the cam assembly is further configured to limit the rotation angle of the cam so that the cam switches between the concave portion of its edge interfering with the side opposite to the receiving groove and the opening and the convex portion of its edge interfering with the side opposite to the receiving groove and the opening.

[0015] Optionally, the cam assembly comprises:

[0016] A first shielding portion is provided on the vertical beam body;

[0017] The second shielding portion is spaced apart from the first shielding portion and is arranged on the vertical beam body.

[0018] The third blocking portion is disposed on an edge of the cam and is configured to move between the first blocking portion and the second blocking portion to limit a rotation angle of the cam.

[0019] Optionally, the linkage structure has an interference portion extending along its retraction direction, and the interference portion is used to interfere with the edge of the cam so that the linkage structure and the cam push each other.

[0020] Optionally, the vertical beam body is configured to retract into the second door body when the second door body is opened, and drive the linkage structure to move along the direction in which it extends.

[0021] Optionally, the transmission assembly further includes:

[0022] The third transmission arm is pivotally arranged in the storage compartment, and the two connecting parts located on both sides of the pivot axis are fixedly connected to the first transmission arm and the second transmission arm respectively so as to drive each other to move in opposite directions.

[0023] Optionally, the refrigerator further comprises:

[0024] The power assembly is configured to drive the vertical beam body to retract into the accommodating groove when the first door body and / or the second door body are opened.

[0025] Optionally, the power assembly includes:

[0026] A first suction member is provided on a side of the vertical beam body facing the receiving groove;

[0027] The second suction member is arranged on a side of the accommodating groove opposite to the opening, and cooperates with the first suction member to controllably retract the vertical beam body into the accommodating groove.

[0028] Optionally, the linkage structure has a limiting portion, which is located inside the second door body and is used to prevent the linkage structure from escaping from the second door body.

[0029] The present invention provides a refrigerator. The refrigerator includes a storage compartment with an opening, a first door body and a second door body pivotally arranged on both sides of the opening, a transmission assembly, a linkage structure, a cam assembly and a vertical beam body. The transmission assembly is arranged in the storage compartment, and includes a first transmission arm and a second transmission arm arranged toward the front side of the refrigerator and capable of moving forward and backward; wherein the first transmission arm and the second transmission arm can drive each other to move in opposite directions. The linkage structure is telescopically assembled on the second door body along the thickness direction of the second door body, and is configured to be pushed by the second transmission arm to move in the direction of its retraction when the second transmission arm moves forward, and to push the second transmission arm to move backward when it moves in the direction of its extension. The cam assembly includes a cam rotatably arranged in the second door body along the vertical direction; the cam is configured to be driven by the linkage structure to rotate in the first direction when the linkage structure moves in the direction of its retraction, and to drive the linkage structure to move in the direction of its extension when it rotates in the second direction. The vertical beam body is retractably mounted to the second door body in a transverse direction thereof. It cooperates with the cam assembly so that when the cam closes the first door body, the first door body pushes the first transmission arm backward. When the cam rotates in a first direction, it pushes the vertical beam body out of the second door body to contact the first door body. When the first door body opens, the vertical beam body retracts into the second door body while simultaneously driving the cam to rotate in a second direction. Since the vertical beam body extends out of the second door body to contact the first door body when the first door body closes, this seals the gap between the first and second door bodies to ensure the sealing of the entire refrigerator. When the first door body opens, the vertical beam body retracts into the second door body, preventing the vertical beam body from obstructing the access to items in the refrigerator.

[0040] like Figures 1 to 7 As shown, this embodiment provides a refrigerator 10. The refrigerator 10 includes a storage compartment 100 having an opening 110, a first door 210 and a second door 220 pivotally disposed on both sides of the opening 110, a transmission assembly 300, a linkage structure 400, a cam assembly, and a vertical beam body 500.

[0041] The transmission assembly 300 is arranged in the storage compartment 100, and includes a first transmission arm 310 and a second transmission arm 320 arranged toward the front side of the refrigerator 10 and capable of moving forward and backward; wherein the first transmission arm 310 and the second transmission arm 320 can drive each other to move in opposite directions.

[0042] The linkage structure 400 is telescopically assembled on the second door body 220 along the thickness direction of the second door body 220, and is configured to be pushed by the second transmission arm 320 to move in the direction of its retraction when the second transmission arm 320 moves forward, and to push the second transmission arm 320 to move backward when moving in the direction of its extension.

[0043] The cam assembly includes a cam 710 rotatably arranged in the second door body 220 along the vertical direction; the cam 710 is configured to be driven by the linkage structure 400 to rotate along the first direction when the linkage structure 400 moves along its retraction direction, and when it rotates along the second direction, it drives the linkage structure 400 to move toward its extension direction.

[0044] The vertical beam body 500 is telescopically assembled on the second door body 220 along the transverse direction of the second door body 220, and cooperates with the cam assembly to enable the cam 710 to close the opening 110 in the first door body 210, and the first door body 210 pushes the first transmission arm 310 to move backward. When the cam 710 rotates along the first direction, it pushes the vertical beam body 500 to extend out from the second door body 220 to resist the first door body 210; when the first door body 210 opens the opening 110, the vertical beam body 500 retracts into the second door body 220 and drives the cam 710 to rotate along the second direction.

[0045] In this embodiment, the type of refrigerator 10 is not limited and can be selected according to needs. For example, the refrigerator 10 can be a refrigerator, a refrigerator-freezer, or a freezer. The refrigerator 10 can be a double-door refrigerator, a three-door refrigerator, or a four-door refrigerator. The refrigerator 10 can be an upright refrigerator, a horizontal refrigerator, or a desktop refrigerator. As a specific embodiment, Figure 7 As shown, the refrigerator 10 is a four-door refrigerator.

[0046] The type of the storage compartment 100 is not limited and can be a refrigerator compartment, a freezer compartment or a variable temperature compartment. The opening 110 is located at the front side of the storage compartment 100. The first door 210 and the second door 220 are pivotally arranged on both sides of the opening 110, that is, the first door 210 and the second door 220 are pivotally arranged on the left and right sides of the opening 110. As a specific embodiment, Figure 1 As shown, the first door body 210 is pivotally disposed on the right side of the opening 110 , and the second door body 220 is pivotally disposed on the left side of the opening 110 .

[0047] In this embodiment, the location of the transmission assembly 300 is not limited and can be selected as needed. For example, the transmission assembly 300 can be set at the top of the compartment, the bottom of the compartment, or the middle of the compartment. The transmission assembly 300 can be set on the left side, the right side, or the middle of the compartment. As long as the first door body 210 can push the first transmission arm 310 to move backward when closing the opening 110, the second transmission arm 320 and the linkage structure 400 can push each other. As a specific embodiment, Figures 1 to 3 As shown, the transmission assembly 300 is arranged at the top of the compartment, at the junction of the first door body 210 and the second door body 220, that is, at the middle of the top of the compartment. Obviously, this is only exemplary and not exclusive.

[0048] In this embodiment, the first transmission arm 310 and the second transmission arm 320 are both disposed toward the front of the refrigerator 10. This facilitates mutual transmission of force between the first door 210 and the first transmission arm 310 when the first door 210 opens and closes the opening 110. This facilitates mutual pushing of the second transmission arm 320 and the linkage structure 400.

[0049] In some other embodiments, both the first transmission arm 310 and the second transmission arm 320 protrude from the storage compartment 100, that is, both the first transmission arm 310 and the second transmission arm 320 extend from the front side of the compartment. This allows the first door 210 to push the first transmission arm 310, and the linkage structure 400 and the second transmission arm 320 to push each other, without changing the structures of the first door 210 and the second door 220. Obviously, this is merely an example and is not exclusive.

[0050] The first transmission arm 310 and the second transmission arm 320 can drive each other to move in opposite directions. That is, when the first transmission arm 310 moves backward, the first transmission arm 310 drives the second transmission arm 320 forward. When the first transmission arm 310 moves forward, the first transmission arm 310 drives the second transmission arm 320 backward. Correspondingly, when the second transmission arm 320 moves backward, the second transmission arm 320 drives the first transmission arm 310 forward. When the second transmission arm 320 moves forward, the second transmission arm 320 drives the first transmission arm 310 backward.

[0051] In other embodiments, such as Figures 1 to 3 As shown, the storage compartment 100 has a first limiting groove and a second limiting groove arranged along the front-to-back direction. The first limiting groove is used to allow the first transmission arm 310 to pass through it and to define the movement direction of the first transmission arm 310. The second limiting groove is used to allow the second transmission arm 320 to pass through it and to define the movement direction of the second transmission arm 320. Specifically, the first limiting groove and the second limiting groove are provided at the top of the compartment.

[0052] In this embodiment, the specific components of the transmission assembly 300 are not limited and can be selected as needed. The transmission assembly 300 can move the first transmission arm 310 and the second transmission arm 320 in the front-to-back direction, and the first transmission arm 310 and the second transmission arm 320 can drive each other to move in opposite directions. For example, the first transmission arm 310 and the second transmission arm 320 each have a rack, and the transmission assembly 300 also includes a gear assembly. The gear assembly meshes the rack of the first transmission arm 310 with the rack of the second transmission arm 320, so that the first transmission arm 310 and the second transmission arm 320 can drive each other to move in opposite directions.

[0053] For example, Figures 1 to 3 As shown, the transmission assembly 300 includes a third transmission arm 330. The third transmission arm 330 is pivotally disposed on the storage compartment 100, and two connecting portions 332 located on both sides of its pivot axis 331 are fixedly connected to the first transmission arm 310 and the second transmission arm 320 respectively so as to drive each other to move in opposite directions.

[0054] In this embodiment, the shapes of the first transmission arm 310 and the second transmission arm 320 are not limited and can be selected according to needs. For example, the first transmission arm 310 and the second transmission arm 320 can be strip-shaped or other irregular shapes.

[0055] In this embodiment, the linkage structure 400 is telescopically assembled to the second door body 220 along the thickness direction of the second door body 220. That is, the linkage structure 400 retracts toward the second door body 220 along the thickness direction of the second door body 220, or the linkage structure 400 can also extend toward the second door body 220 along the thickness direction of the second door body 220.

[0056] In other embodiments, the linkage structure 400 extends from the inner surface of the second door 220, that is, the linkage structure 400 is not entirely located inside the second door 220, nor is it entirely located outside the second door 220. The inner surface of the second door 220 refers to the surface of the second door 220 facing the opening 110.

[0057] When the second transmission arm 320 moves forward, the linkage structure 400 is pushed by the second transmission arm 320 to move in the direction of its retraction. In other words, as a specific embodiment, Figures 1 to 3 As shown, when the second transmission arm 320 moves forward, the second transmission arm 320 pushes the linkage structure 400 to move forward, and the linkage structure 400 moves in the retracting direction. When the linkage structure 400 moves in the extending direction, it pushes the second transmission arm 320 to move backward. In other words, as a specific embodiment, Figures 1 to 3As shown, when the linkage structure 400 moves toward the rear side of the refrigerator 10, that is, when the linkage structure 400 moves toward the extending direction, the linkage structure 400 pushes the second transmission arm 320 to move toward the rear side of the refrigerator 10. As a specific embodiment, Figures 1 to 3 As shown, when the second door body 220 closes the opening 110 , the thickness direction of the second door body 220 refers to the front-to-back direction of the refrigerator 10 , and the transverse direction of the second door body 220 refers to the left-to-right direction of the refrigerator 10 .

[0058] The cam 710 is rotatably disposed vertically within the second door 220. That is, the rotation axis of the cam 710 is disposed vertically. In this embodiment, the specific directions of the first and second directions are not limited and can be selected as needed. As a specific embodiment, when viewed from above the refrigerator 10, the first direction is counterclockwise and the second direction is clockwise. Obviously, this is merely exemplary. For example, the first direction is clockwise and the second direction is counterclockwise.

[0059] In this embodiment, the specific components of the cam assembly are not limited and can be selected according to needs. Figure 3 As shown, the cam assembly includes a cam 710, a receiving groove 720, a first shielding portion 730, a second shielding portion 740 and a third shielding portion 750. Obviously, this is only exemplary and not exclusive. For example, the cam assembly only includes the cam 710.

[0060] In this embodiment, the material of the vertical beam body 500 is not limited and can be selected as needed. As a specific embodiment, at least the portion of the vertical beam body 500 extending from the second door body 220 is made of an elastic material. In other words, the portion of the vertical beam body 500 adjacent to the first door body 210 is made of an elastic material.

[0061] The vertical beam body 500 is telescopically assembled on the second door body 220 along the transverse direction of the second door body 220. As a specific embodiment, Figure 3 As shown, when the second door body 220 is in a state of closing the opening 110 , the vertical beam body 500 is extended and retracted along the transverse direction of the second door body 220 , that is, along the left-right direction.

[0062] In this embodiment, the vertical beam body 500 cooperates with the cam assembly so that when the cam 710 rotates in a first direction, the vertical beam body 500 is pushed out from the second door body 220. When the vertical beam body 500 retracts into the second door body 220, the cam 710 is driven to rotate in a second direction. In this embodiment, the specific manner in which the vertical beam body 500 cooperates with the cam assembly is not limited and can be selected according to needs.

[0063] For example, the cam 710 is pivotally mounted on the vertical beam body 500 and configured to rotate in a first direction from a concave portion of its edge to a convex portion thereof, thereby contacting the side opposite the receiving groove 720 and the opening 721, thereby pushing the vertical beam body 500 out of the second door body 220. When the cam 710 rotates in a second direction, it rotates from a convex portion of its edge to a concave portion thereof, thereby contacting the side opposite the receiving groove 720 and the opening 721, thereby freeing space for the vertical beam body 500 to retract. The first blocking portion 730, the second blocking portion 740, and the third blocking portion 750 are used to limit the rotation angle of the cam 710. Obviously, this is merely exemplary and not exclusive.

[0064] For example, the cam 710 is pivotally disposed on a side of the receiving groove 720 opposite the opening 721. When the cam 710 rotates in a first direction, it rotates from a recessed position on its outer edge to a protruding position on its outer edge, thereby contacting the vertical beam body 500 and pushing the vertical beam body 500 out of the second door body 220. When the vertical beam body 500 retracts into the second door body 220, it pushes the cam 710 to rotate in a second direction, and the cam 710 rotates from a protruding position on its outer edge to a recessed position on its outer edge, thereby contacting the vertical beam body 500. For example, the cam 710 is pivotally disposed on a sidewall of the second door body 220, etc.

[0065] When the first door 210 closes the opening 110, the vertical beam body 500 extends from the second door 220 to contact the first door 210, thereby sealing the gap between the first door 210 and the second door 220 to ensure the sealing of the entire refrigerator 10. When the first door 210 opens the opening 110, the vertical beam body 500 retracts into the second door 220, thereby preventing the vertical beam body 500 from blocking the access to and placement of items in the refrigerator.

[0066] In some other embodiments, the cam assembly includes a receiving groove 720. The receiving groove 720 is provided on a side of the second door body 220 opposite to the pivot axis thereof, and its opening direction is opposite to the pivot axis of the second door body 220, and is used for allowing the vertical beam body 500 to extend from the opening or retract into the opening along the lateral direction of the second door body 220;

[0067] The cam 710 is pivotally disposed on the vertical beam body 500, and is configured to rotate from the concave portion of its edge to the convex portion of its edge to abut against the side opposite to the accommodating groove 720 and the opening when rotating in a first direction, and to rotate from the convex portion of its edge to the concave portion of its edge to abut against the side opposite to the accommodating groove 720 and the opening when rotating in a second direction.

[0068] The accommodating groove 720 is provided on the side of the second door body 220 opposite to the pivot axis thereof, that is, the accommodating groove 720 is provided on the side of the second door body 220 close to the first door body. Figure 3As shown, the receiving groove 720 is disposed on the right side of the second door body 220. The opening direction of the receiving groove 720 is opposite to the pivot axis of the second door body 220, that is, the opening direction of the receiving groove 720 is toward the right. The side of the receiving groove 720 opposite to the opening refers to the side of the receiving groove 720 closer to the pivot axis of the second door body 220, that is, the left side of the receiving groove 720.

[0069] In this embodiment, the location of the cam 710 on the vertical beam body 500 is not limited and can be selected as needed. As a specific embodiment, the cam 710 is located on the side of the vertical beam body 500 facing the pivot axis of the second door body 220 and is located on the upper side of the vertical beam body 500. Obviously, this is only an example and is not exclusive.

[0070] In this embodiment, the protrusion and recess of the edge of the cam 710 are relative. The protrusion of the edge of the cam 710 does not refer to the most protruding part of the edge of the cam 710. The recess of the edge of the cam 710 does not refer to the most recessed part of the edge of the cam 710. As long as the recess and protrusion of the edge of the cam 710 respectively contact the left side of the accommodating groove 720 to meet the travel of the vertical beam body 500 to retract into the second door body 220, the refrigerator structure is simple and compact.

[0071] In some other embodiments, the cam assembly is further configured to limit the rotation angle of the cam 710 so that the cam 710 switches between the concave portion of its edge interfering with the side opposite the receiving groove 720 and the opening and the convex portion of its edge interfering with the side opposite the receiving groove 720 and the opening.

[0072] In other words, the rotation angle of the cam 710 only needs to satisfy the extension and retraction stroke of the vertical beam body 500. In other words, the rotation angle of the cam 710 only needs to satisfy the switching between the concave portion of the edge of the cam 710 abutting against the left side of the receiving groove 720 and the convex portion of the edge of the cam 710 abutting against the left side of the receiving groove 720.

[0073] In this embodiment, the manner in which the cam assembly limits the rotation angle of the cam 710 is not limited and can be selected as needed, which makes the operation of the vertical beam body 500 more stable.

[0074] In some other embodiments, the cam assembly includes a first shielding portion 730, a second shielding portion 740, and a third shielding portion 750. The first shielding portion 730 is disposed on the vertical beam body 500. The second shielding portion 740 is disposed on the vertical beam body 500 at a distance from the first shielding portion 730. The third shielding portion 750 is disposed at the edge of the cam 710 and is configured to move between the first shielding portion 730 and the second shielding portion 740 to limit the rotation angle of the cam 710. This results in a simple structure and stable operation of the cam 710.

[0075] In some other embodiments, the linkage structure has a resisting portion 410 extending along its retraction direction, and the resisting portion 410 is used to resist the edge of the cam 710 so that the linkage structure and the cam 710 push each other. This makes the cam 710 simple in structure and stable in operation.

[0076] In some other embodiments, the vertical beam body 500 is configured to retract into the second door body 220 when the second door body 220 opens the opening 110 , and drive the linkage structure 400 to move along the direction in which it extends.

[0077] When the second door 220 opens the opening 110, the second transmission arm 320 no longer applies thrust to the linkage structure 400, and the vertical beam body 500 is driven by the power assembly to retract into the second door 220. When the second door 220 is opened, the vertical beam body 500 retracts into the second door 220, which can prevent accidental contact with the vertical beam body 500.

[0078] In some other embodiments, the transmission assembly 300 includes a third transmission arm 330. The third transmission arm 330 is pivotally disposed on the storage compartment 100, and two connecting portions 332 located on both sides of the pivot axis 331 thereof are fixedly connected to the first transmission arm 310 and the second transmission arm 320 respectively so as to drive each other to move in opposite directions.

[0079] In this embodiment, the shape of the third transmission arm 330 is not limited and can be selected as needed. For example, the third transmission arm 330 can be a bar or other irregular shape. The two connecting parts 332 located on both sides of the pivot axis 331, that is, the two connecting parts 332 are located on both sides of the pivot axis 331 of the third transmission arm 330. Figure 6 As shown, the two connecting portions 332 are respectively located at the left and right ends of the pivot shaft 331 of the third transmission arm 330 .
