Description

Technical Field

[0001] The present invention relates to the field of refrigeration equipment, in particular to 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:

[0010] The gear assembly is respectively engaged with the first rack portion and the second rack portion, and when the first door body closes the opening, the first door body pushes the first transmission arm to move backward, thereby causing the linkage structure to move along its retraction direction and drive the vertical beam body to extend out of the second door body to resist the first door body; when the first door body opens the opening, the vertical beam body retracts into the second door body and drives the linkage structure to move along its extension direction.

[0011] Optionally, when the teeth of the first rack portion face the retraction direction of the vertical beam body, the teeth of the second rack portion face the retraction direction of the linkage structure; or, when the teeth of the first rack portion face the extension direction of the vertical beam body, the teeth of the second rack portion face the extension direction of the linkage structure.

[0012] Optionally, the gear assembly includes

[0013] The gear is provided at the intersection of the first rack portion and the second rack portion and is meshed with the first rack portion and the second rack portion respectively.

[0014] 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.

[0015] Optionally, the transmission assembly further includes:

[0016] 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.

[0019] 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.

[0020] Optionally, the power assembly includes:

[0021] A first suction member is provided on a side of the vertical beam body facing the receiving groove;

[0022] 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.

[0023] Optionally, the first attraction member includes a magnet, and the second attraction member includes an electromagnetic member.

[0024] 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.

[0025] The present invention provides a refrigerator, which includes a storage compartment with an opening, a first door body and a second door body pivotally arranged on both sides of the opening in the transverse direction, a transmission assembly, a linkage structure, a vertical beam body and a gear transmission mechanism.

The gear assembly engages with the first rack portion and the second rack portion, respectively. When the first door is closed, the first door pushes the first transmission arm backward, causing the linkage structure to move in its retracted direction, driving the vertical beam body to extend from the second door body to contact the first door body. When the first door is opened, the vertical beam body retracts into the second door body and simultaneously drives the linkage structure to move in its extended direction. Since the vertical beam body extends from the second door body to contact the first door body when the first door is closed, the gap between the first and second door bodies is sealed to ensure the sealing of the entire refrigerator. When the first door is opened, the vertical beam body retracts into the second door body, preventing the vertical beam body from blocking the access to items in the compartment.

[0036] like Figures 1 to 7 As shown, this embodiment provides a refrigerator 10, which includes a storage compartment 100 with an opening 110, a first door body 210 and a second door body 220 pivotally arranged on both sides of the opening 110, as well as a transmission assembly 300, a linkage structure 400, a vertical beam body 500 and a gear transmission mechanism.

[0037] The transmission assembly 300 is provided in the storage compartment 100 and includes a first transmission arm 310 and a second transmission arm 320 disposed toward the front of the refrigerator 10 and capable of moving forward and backward. The first transmission arm 310 and the second transmission arm 320 can drive each other to move in opposite directions.

[0038] The linkage structure 400 is telescopically assembled on the second door body 220 along the thickness direction of the second door body 220, and has a first rack portion 410 extending along its telescopic direction. It 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.

[0039] The vertical beam body 500 is telescopically assembled to the second door body 220 along the transverse direction of the second door body 220 and has a second rack portion 510 extending along the telescopic direction thereof.

[0040] The gear assembly is respectively engaged with the first rack portion 410 and the second rack portion 510, and when the first door body 210 closes the opening 110, the first door body 210 pushes the first transmission arm 310 to move backward, thereby causing the linkage structure 400 to move along its retraction direction and drive the vertical beam body 500 to extend from the second door body 220 to resist the first door body 210; the vertical beam body 500 retracts into the second door body 220 when the first door body 210 opens the opening 110, and at the same time drives the linkage structure 400 to move along its extension direction.

[0041] 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 4 As shown, the refrigerator 10 is a four-door refrigerator.

[0042] 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 .

[0043] 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.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] For example, Figures 1 to 3As 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.

[0050] 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.

[0051] 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, and the linkage structure 400 can also extend toward the second door body 220 along the thickness direction of the second door body 220.

[0052] 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.

[0053] 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 3 As 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 4 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 .

[0054] 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.

[0055] The specific arrangement positions of the first rack portion 410 and the second rack portion 510 are not limited, and the type and quantity of the gears 710 included in the gear assembly are not limited and can be selected as needed. The first rack portion 410, the second rack portion 510 and the gear assembly cooperate to convert the movement of the linkage structure 400 along the thickness direction of the second door body 220 into the lateral movement of the vertical beam body 500 along the second door body 220. Conversely, the first rack portion 410, the second rack portion 510 and the gear assembly cooperate to convert the lateral movement of the vertical beam body 500 along the second door body 220 into the movement of the linkage structure 400 along the thickness direction of the second door body 220. As a specific embodiment, Figures 1 to 4 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 .

[0056] As a specific example, Figure 3 As shown, the first rack portion 410 and the second rack portion 510 are arranged crosswise. The teeth of the first rack portion 410 face the direction of retraction of the vertical beam body 500, that is, the teeth of the first rack portion 410 face the left. The teeth of the second rack portion 510 face the direction of retraction of the linkage structure 400, that is, the teeth of the second rack portion 510 face the front. In this case, the gear assembly structure is the simplest, requiring only a single gear 710. Obviously, this is merely an example and not the only option. For example, the teeth of the first rack portion 410 can face upward, downward, or in the direction of extension of the vertical beam body 500. The teeth of the second rack portion 510 can face upward, downward, or in the direction of extension of the linkage structure 400. In this case, the number and type of gears 710 included in the gear assembly can be varied to meet the movement of the vertical beam. For example, the gear assembly can include multiple gears or bevel gears.

[0057] As can be seen from the above description, in this embodiment, the number and type of gears 710 included in the gear assembly are not limited and can be selected as needed. The gear assembly is engaged with the first rack portion 410 and the second rack portion 510 respectively to meet the following conditions. That is, when the gear assembly closes the opening 110 of the first door body 210, the first door body 210 pushes the first transmission arm 310 to move backward, and the second transmission arm 320 moves forward, the second transmission arm 320 then causes the linkage structure 400 to move in its retracted direction, driving the vertical beam body 500 to extend from the second door body 220 to resist the first door body 210. When the gear assembly opens the opening 110 of the first door body 210 and the vertical beam body 500 retracts into the second door body 220, it drives the linkage structure 400 to move in its extended direction.

[0058] 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.

[0059] In some other embodiments, when the teeth of the first rack portion 410 face the retraction direction of the vertical beam body 500, the teeth of the second rack portion 510 face the retraction direction of the linkage structure 400. Alternatively, when the teeth of the first rack portion 410 face the extension direction of the vertical beam body 500, the teeth of the second rack portion 510 face the extension direction of the linkage structure 400.

[0060] In other words, as a specific embodiment, Figure 3 As shown, when the teeth of the first rack portion 410 face left, the teeth of the second rack portion 510 face front. When the teeth of the first rack portion 410 face right, the teeth of the second rack portion 510 face rear. Figure 3 As shown, this simplifies the structure of the gear assembly, requiring only one gear 710 .

[0061] In some other embodiments, the gear assembly includes a gear 710. The gear 710 is disposed at the intersection of the first rack portion 410 and the second rack portion 510 and is meshed with the first rack portion 410 and the second rack portion 510, respectively. This simplifies the structure of the gear assembly, requiring only one gear 710.

[0062] 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.

[0063] 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.

[0064] 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.

[0065] 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 5 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 .

[0066] In this embodiment, the method for fixing the third transmission arm 330 to the first transmission arm 310 and the second transmission arm 320 is not limited and can be selected as needed. For example, the third transmission arm 330 can be integrally formed with the first transmission arm 310 and the second transmission arm 320 or fixedly connected via fasteners. This structure of the transmission assembly 300 is simple and easy to control.

[0067] In some other embodiments, the second door body 220 has a receiving groove 221 on the side opposite to its pivot axis, and the opening direction of the receiving groove 221 is opposite to the pivot axis of the second door body 220. The receiving groove 221 is used for the vertical beam body 500 to extend from or retract into it.

[0068] The accommodating groove 221 is provided on the side of the second door body 220 opposite to the pivot axis thereof. Figure 1 As shown, when the pivot axis of the second door body 220 is located on the left side of the second door body 220 , the accommodating groove 221 is located on the right side of the second door body 220 .

[0069] The opening direction of the receiving groove 221 is opposite to the side of the pivot axis of the second door body 220, that is, as a specific embodiment, Figure 1 As shown, when the pivot axis of the second door 220 is located on the left side of the second door 220, the opening of the receiving groove 221 faces rightward. This facilitates the extension or retraction of the vertical beam body 500 therein. The receiving groove 221 is adapted to the shape of the vertical beam body 500 and also serves to define the movement direction of the vertical beam body 500.

[0070] In some other embodiments, the refrigerator 10 further includes a power assembly configured to drive the vertical beam body 500 to retract into the receiving groove 221 when the first door 210 and / or the second door 220 opens the opening 110 .

[0071] In this embodiment, the type of power assembly is not limited and can be selected as needed. For example, the power assembly drives the vertical beam body 500 to retract into the receiving groove 221 through the gear and rack. For example, the power assembly drives the vertical beam body 500 to retract into the receiving groove 221 through the elastic force storage structure. For example, the power assembly provides power through the magnetic structure to drive the vertical beam body 500 to retract into the receiving groove 221. The power assembly allows the vertical beam body 500 to retract into the receiving groove 221 when the first door body 210 and / or the second door body 220 opens the opening 110, which can avoid affecting the taking and placing of items and accidentally touching the vertical beam body 500.

[0072] In some other embodiments, the power assembly includes a first suction member 610 and a second suction member. The first suction member 610 is disposed on the side of the vertical beam body 500 facing the receiving groove 221. The second suction member is disposed on the side of the receiving groove 221 opposite the opening 222 and cooperates with the first suction member 610 to controllably retract the vertical beam body 500 into the receiving groove 221.

[0073] The first attraction member 610 can be a magnet, a permanent magnet or an electromagnetic member. As a specific embodiment, the first attraction member 610 is a magnet. The number of the first attraction member 610 is not limited and can be selected as needed. As a specific embodiment, Figure 7 As shown, there are multiple first suction members 610 , which are spaced apart along the vertical direction of the vertical beam body 500 .

[0074] The side of the vertical beam body 500 facing the accommodating groove 221 is, as a specific embodiment, the left side of the vertical beam body 500 .

[0075] The second engaging member can be a magnet, a permanent magnet, or an electromagnetic member. As a specific embodiment, the second engaging member is an electromagnetic member. The number of second engaging members is not limited and can be selected as needed. As a specific embodiment, the number of second engaging members is multiple, and they are arranged in a one-to-one correspondence with the first engaging member 610.

[0076] The second suction member is disposed on the side of the accommodating groove 221 opposite to the opening 222 . As a specific embodiment, the opening 222 is provided on the right side of the accommodating groove 221 , and the second suction member is disposed on the left side of the accommodating groove 221 .

[0077] In some other embodiments, the first attraction member 610 includes a magnet, and the second attraction member includes an electromagnetic member, which facilitates controlling the vertical beam body 500 to retract into the receiving groove 221 .
