Description

Technical Field

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

[0002] In French door and multi-door refrigerators, a hinged flip beam is installed on one of the two doors. When the door containing the flip beam is closed, the flip beam flips outwards relative to its host door. When the other door is also closed, the flip beam covers the gap between the two doors to prevent cold air leakage. When the door containing the flip beam is opened, the flip beam flips inwards relative to its host door to avoid interference with the other door.

[0003] In related technologies, the top of the box liner is provided with a guide rail for cooperating with the flip beam; the flip beam includes a beam body and a guide block provided on the top of the beam body. The beam body is rotatably mounted on the door body, and the guide block slides along the guide rail during the rotation of the flip beam to limit the movement path of the flip beam and prevent it from shifting or misaligning when flipping.

[0004] However, as the guide block slides along the guide rail, it will make a hard collision with the side wall of the guide rail, resulting in loud noise during the opening and closing of the refrigerator door. Utility Model Content

[0005] This application provides a refrigerator that can solve the technical problem of excessive noise during the opening and closing of the refrigerator door.

[0006] In a first aspect, embodiments of this application provide a refrigerator, comprising:

[0007] The housing is constructed with guide grooves;

[0008] Two doors that open outwards;

[0009] A flip beam, installed in one of the two door panels, comprises:

[0010] Support, connected to the door body;

[0011] The beam body is rotatably mounted on the support, and the beam body has a first position and a second position;

[0012] The drive mechanism is located on the beam body and is connected to the support for transmission, and drives the support to rotate relative to the beam body.

[0013] The guide member is slidably disposed on the beam body along the width direction of the beam body. The guide member is constructed with a first guide rail and a second guide rail arranged and connected along the width direction. The first guide rail is closer to the top of the beam body than the second guide rail.

[0014] The transmission mechanism is connected to the support and the guide member respectively, so as to drive the guide member to slide when the support rotates relative to the beam body;

[0015] A locking structure is slidably disposed on the beam body along the height direction of the beam body. The locking structure includes a sliding member and a locking member located at the top. The sliding member is slidably disposed on the first guide rail or the second guide rail.

[0016] When the beam body rotates to the first position, the width direction of the beam body is parallel to the width direction of the door body, the sliding member slides on the first guide rail, and the locking member extends into the guide groove.

[0017] When the beam body rotates to the second position, the width direction of the beam body is perpendicular to the width direction of the door body, the sliding member slides on the second guide rail, and the locking member moves downward out of the guide groove.

[0018] In the refrigerator of this embodiment, the beam body is flipped by a drive mechanism, and when the beam body is flipped, the locking structure is automatically raised and lowered by a transmission mechanism and a guide member. There is no need to rely on the rigid collision between the guide member and the guide groove to guide the flipping action of the beam body, which reduces the possibility of the guide member colliding with the groove wall of the guide groove, thereby reducing the noise generated by the refrigerator during the opening and closing process.

[0019] In some embodiments of this application, the guide member is constructed with a rack that extends along the width direction of the beam body;

[0020] The transmission mechanism includes a gear, which is fixedly connected to the support; the gear meshes with a rack.

[0021] With this configuration, the support rotates relative to the beam body, and the gear rotates with the support. Since the gear meshes with the rack, the gear drives the rack to move along the width direction of the beam body, which in turn drives the guide component to move along the width direction of the beam body.

[0022] In some embodiments of this application, the beam body is constructed with a groove that extends along the width direction of the beam body;

[0023] The guide component is equipped with a slider, which slides within a groove.

[0024] With this configuration, the slider is placed in the groove, allowing the guide component to slide relative to the beam body along the width direction of the beam body.

[0025] In some embodiments of this application, the first guide rail and the second guide rail extend along the width direction of the beam body, respectively;

[0026] The guide component is also equipped with a transition guide rail, which is located between the first guide rail and the second guide rail. The two ends of the transition guide rail are connected to the first guide rail and the second guide rail, respectively. The distance between the transition guide rail and the top of the beam body increases from the end closer to the first guide rail to the end closer to the second guide rail.

[0027] With this configuration, the first and second guide rails extend along the width of the beam body. This prevents the slider from shifting within the first or second guide rail under the weight of the locking structure when it slides on it. When the drive mechanism is not in operation, the slider remains within the first or second guide rail, thus maintaining the height of the portion of the locking member extending beyond the top of the beam body. A transition guide rail connects the first and second guide rails, facilitating easier movement of the slider between them.

[0028] In some embodiments of this application, the transition guide extends along a curve.

[0029] This design makes the transition rail smoother, allowing the sliding component to change its direction of movement within the transition rail more gradually. This reduces friction between the sliding component and the transition rail, making the sliding component move more smoothly along the transition rail.

[0030] In some embodiments of this application, the guide member includes a connecting plate, on which a first guide rail and a second guide rail are configured;

[0031] The first guide rail is a first guide hole extending along the width direction of the beam body;

[0032] The second guide rail is a second guide hole extending along the width direction of the beam body.

[0033] This design simplifies the structure of the first and second guide holes, making them easier to manufacture and improving the production efficiency of the flip beam.

[0034] In some embodiments of this application, the slider includes:

[0035] The sliding part is slidably disposed in the first guide hole or the second guide hole; the two ends of the sliding part extend to the outside of the connecting plate along the thickness direction of the connecting plate respectively;

[0036] The first stop is connected to one end of the sliding part along the thickness direction of the connecting plate and is used to cooperate with the plate surface stop of the connecting plate.

[0037] The second stop is connected to the other end of the sliding part along the thickness direction of the connecting plate, and is used to cooperate with the plate surface stop of the connecting plate.

[0038] With this configuration, the first stop and the second stop prevent the sliding part from easily coming out of the first guide hole or the second guide hole.

[0039] In some embodiments of this application, the locking structure further includes a connector that extends along the height direction of the beam body and is slidably disposed on the beam body; the top end of the connector is connected to the locking member, and the bottom end of the connector is connected to the sliding member.

[0040] With this configuration, the locking element and the sliding element are connected by a connector.

[0041] In some embodiments of this application, the tilting beam further includes a limiting mechanism, which includes:

[0042] A connecting seat is attached to the beam body. The connecting seat has a connecting hole and a stop surface.

[0043] The telescopic block is telescopically mounted on the connecting seat, with a portion of the telescopic block extending outside the connecting hole. The portion of the telescopic block extending outside the connecting hole has a guide surface and a limiting surface, with the guide surface and the limiting surface located on opposite sides of the telescopic block along the width direction of the beam body. The limiting surface is opposite to the stop surface and encloses a limiting area.

[0044] The first elastic element is disposed between the connecting seat and the telescopic block. The first elastic element is used to apply elastic force to the telescopic block so that the telescopic block and the connecting seat stop cooperate.

[0045] The support structure has a stop protrusion;

[0046] During the process of the beam body rotating from the first position to the second position, the stop protrusion slides along the guide surface to the limiting surface, and moves to the limiting area when the beam body rotates to the second position.

[0047] With this configuration, when the stop protrusion moves to the limiting area, the stop surface stops the stop protrusion to prevent it from continuing to rotate away from the guide surface. This limits the rotation position of the beam body when the door is opened, reducing the possibility of the beam body rotating too much.

[0048] As the door gradually closes from its open position, the support rotates relative to the beam body toward the guide surface, the stop protrusion presses against the limiting surface, and passes over the telescopic block. When the stop protrusion separates from the guide surface, the telescopic block returns to its original position under the action of the first elastic element.

[0049] Secondly, embodiments of this application provide a refrigerator, comprising:

[0050] The housing is constructed with guide grooves;

[0051] Two doors that open outwards;

[0052] A flip beam, installed in one of the two door panels, comprises:

[0053] Support, connected to the door body;

[0054] The beam body is rotatably mounted on the support, and the beam body has a first position and a second position;

[0055] The drive mechanism is located on the beam body and is connected to the support for transmission, and drives the support to rotate relative to the beam body.

[0056] A guide member is slidably disposed on the beam body along the width direction of the beam body, and the guide member includes a sliding element;

[0057] The transmission mechanism is connected to the support and the guide member respectively, so as to drive the guide member to slide when the support rotates relative to the beam body;

[0058] A locking structure is slidably disposed on the beam body along the height direction of the beam body. The locking structure includes a locking member located at the top. The bottom of the locking structure is constructed with a first guide rail and a second guide rail arranged and connected along the width direction of the beam body. The first guide rail is farther away from the top of the beam body than the second guide rail.

[0059] When the beam body rotates to the first position, the width direction of the beam body is parallel to the width direction of the door body, the sliding member slides on the first guide rail, and the locking member extends into the guide groove.

[0060] When the beam body rotates to the second position, the width direction of the beam body is perpendicular to the width direction of the door body, the sliding member slides on the second guide rail, and the locking member moves downward out of the guide groove.

[0061] In the refrigerator of this embodiment, the beam body is flipped by a drive mechanism, and when the beam body is flipped, the locking structure is automatically raised and lowered by a transmission mechanism and a guide member. There is no need to rely on the rigid collision between the guide member and the guide groove to guide the flipping action of the beam body, which reduces the possibility of the guide member colliding with the groove wall of the guide groove, thereby reducing the noise generated by the refrigerator during the opening and closing process.

[0090] 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.

[0091] 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.

[0092] 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.

[0093] 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.

[0094] As stated in the background section, refrigerators in related technologies have a problem of excessive noise during the opening and closing of the door. The inventors have discovered that the reason for this problem is that during the opening and closing of the refrigerator door, the guide block at the top of the flip beam slides relative to the guide rail on the refrigerator body. The flip beam is guided by the guide rail. As the guide block slides along the guide rail, it will have a hard collision with the side wall of the guide rail, resulting in excessive noise during the opening and closing of the refrigerator door.

[0095] To address the aforementioned technical problems, this application provides a refrigerator in which a drive mechanism drives a support to rotate relative to the beam body, so that the beam body automatically rotates to a first position when the door is closed and automatically rotates to a second position when the door is open. When the support rotates relative to the beam body, a transmission mechanism drives a guide member to slide. When the beam body rotates to the first position, the sliding member slides onto the first guide rail, and a locking member automatically extends into the guide groove to lock the door position, preventing accidental opening or loosening. When the beam body rotates to the second position, the sliding member slides onto the second guide rail, and the locking member moves downward out of the guide groove to facilitate opening the door. Because the beam body is flipped via the drive mechanism, and the locking structure automatically rises and falls during flipping via the transmission mechanism and guide member, there is no need to rely on rigid collision between the guide member and the guide groove to guide the flipping action of the beam body. This reduces the possibility of collision between the guide member and the groove wall, thereby reducing noise generated during the opening and closing of the refrigerator door.

[0096] 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.

[0097] refer to Figure 1 and Figure 2The refrigerator provided in this application includes a cabinet 10 having a storage compartment 111, a door 20 connected to the cabinet 10 to open and close the storage compartment 111, and a refrigeration device for supplying cold air to the storage compartment 111.

[0098] A refrigeration unit can be installed inside the enclosure 10. The refrigeration unit is used to provide cold air to the storage compartment 111 to lower the temperature inside the storage compartment 111.

[0099] A retrieval opening 112 may be formed on the front side of the storage room 111, through which users can retrieve items from the storage room 111 or place items into the storage room 111.

[0100] 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... Figure 2 The positive direction of the depth Y of the middle cabinet 10 is "front". "Rear side" refers to the side opposite to the front, that is, the side of the refrigerator that faces away from the user during normal use. Figure 2 The negative direction of the depth direction Y of the middle box 10 is "rear".

[0101] It is understood that the number of storage compartments 111 can be one, two, or more than three. Storage compartments 111 can be configured as refrigerators, freezers, or variable temperature compartments with internal temperature variations.

[0102] refer to Figure 2 The box body 10 may include an inner liner 110, which can form a storage room 111 and an access port 112.

[0103] refer to Figure 2 The enclosure 10 may also include a housing 120. The housing 120 is attached to the outside of the inner liner 110 to form the appearance of the enclosure 10.

[0104] The door 20 is rotatably connected to the cabinet 10 to open or close the access port 112. When the door 20 is open, the user can take items from or place items into the storage compartment 111 through the access port 112. When the door 20 is closed, the leakage of cold air from the storage compartment 111 through the access port 112 is reduced, thus improving the refrigerator's cooling effect on the items in the storage compartment 111.

[0105] In the implementation where there is one storage room 111, the storage room 111 is provided with two double doors 20.

[0106] In a configuration where there are multiple storage compartments 111, each storage compartment 111 can be equipped with two double-door doors 20, such as in a French door refrigerator. Alternatively, some storage compartments 111 can be equipped with two double-door doors 20, while other storage compartments 111 can be equipped with one door 20 each, such as... Figure 1 The French-style multi-door refrigerator shown is an example.

[0107] refer to Figure 2 The door body 20 may include a door housing 210, which can be rotatably connected to the housing 10. The door housing 210 has high structural strength, and the rotatable connection between the door housing 210 and the housing 10 can improve the reliability of the connection between the door body 20 and the housing 10.

[0108] refer to Figure 2 The door body 20 may also include a door liner 220. When the door body 20 is in the closed state, the door liner 220 faces the storage compartment 111. The door shell 210 and the door liner 220 form the appearance of the door body 20.

[0109] The door shell 210 and the inner door liner 220 enclose an insulation cavity. The insulation cavity can be filled with insulation material, such as foaming agent. When the door 20 is closed, the insulation material can reduce the heat exchange between the storage compartment 111 and the outside, thus achieving the effect of heat preservation for the storage compartment 111.

[0110] refer to Figure 2 and Figure 3 The refrigerator in this embodiment of the application also includes a flip beam 30, which is rotatably disposed on one of the two doors 20 that are configured to open in opposite directions.

[0111] refer to Figure 3 and Figure 4 When door 20 is closed, the width direction X2 of the flip beam 30 is parallel to the width direction X1 of door 20, and a portion of the flip beam 30 in the width direction is opposite to the door 20 it is located on, while the other portion of the flip beam 30 in the width direction extends to the outside of the door 20 it is located on. When the other door 20 is also closed, the flip beam 30 covers the gap between the two doors 20 to reduce the possibility of cold leakage in the gap between the two doors 20.

[0112] It should be noted that when the door 20 is in the closed state, the width direction X1 of the door 20 is the same as the width direction X of the box 10.

[0113] refer to Figure 2 and Figure 5When the door 20 is in the open state, the width direction X2 of the flip beam 30 is perpendicular to the width direction X1 of the door 20, and the flip beam 30 is opposite to the inner side of the door 20, which reduces the length of the flip beam 30 extending beyond the end of the door 20 in the width direction, thereby reducing the possibility of the flip beam 30 interfering with the other door 20.

[0114] refer to Figure 6 The flip beam 30 in this embodiment may include a beam body 310. The beam body 310 is a long, hollow structure. The beam body 310 extends along the height direction Z of the door body 20. (See reference...) Figure 7 and Figure 8 The beam body 310 may have an installation cavity 311 inside.

[0115] In some possible implementations of the embodiments of this application, reference is made to Figure 6 and Figure 7 The beam body 310 may include a first beam shell 314 and a second beam shell 315, both extending along the height direction Z of the door body 20. The first beam shell 314 and the second beam shell 315 are joined together along the thickness direction of the beam body 310 to form the appearance of the beam body 310. (Reference) Figure 8 The first beam shell 314 and the second beam shell 315 enclose and form the mounting cavity 311.

[0116] When the door 20 containing the flip beam 30 is in the open state, the first beam shell 314 is located in front of the second beam shell 315.

[0117] In some possible implementations of the embodiments of this application, reference is made to Figure 6 and Figure 7 The beam body 310 may also include a cover plate 316, which is connected to the side of the first beam shell 314 opposite to the second beam shell 315. The side of the cover plate 316 opposite to the first beam shell 314 is the visible side to the user. The cover plate 316 can cover the first beam shell 314 and the second beam shell 315, thereby improving the decorative effect of the flip beam 30.

[0118] refer to Figure 6 and Figure 8 The overturning beam 30 in this embodiment may further include a support 320. (See reference...) Figure 9 The support 320 is connected to the door body 20. The beam body 310 is rotatably mounted on the support 320, and the axis of rotation of the beam body 310 relative to the support 320 is approximately parallel to the height direction Z of the door body 20.

[0119] refer to Figure 9In the implementation of the door body 20 including the door inner liner 220, the support 320 can be fixedly connected to the door inner liner 220 so as to install the beam body 310 as close as possible to the inside of the door body 20, thereby reducing the movement path required when the beam body 310 is flipped.

[0120] In some possible implementations of the embodiments of this application, reference is made to Figure 8 The support 320 may include a connecting shaft 321, which may extend along the height direction Z of the beam body 310.

[0121] The connecting shaft 321 is rotatably mounted within the mounting cavity 311. The connecting shaft 321 is rotatably mounted relative to the beam body 310.

[0122] It should be noted that in this embodiment, during the process of the beam body 310 flipping relative to the door body 20, the position of the support 320 relative to the door body 20 remains unchanged, that is, there is no relative rotation between the support 320 and the door body 20. The rotation of the support 320 and the connecting shaft 321 described in this embodiment refers to the rotation of the support 320 relative to the beam body 310, which is actually the rotation of the beam body 310 around the support 320 (or the connecting shaft 321).

[0123] In some possible implementations of this application, the beam body 310 may include a first bracket (not shown in the drawings), on which a first limiting hole may be constructed. The axis of the first limiting hole may be approximately collinear with the axis of the connecting shaft 321. The connecting shaft 321 is rotatably inserted into the first limiting hole so that the connecting shaft 321 is rotatably connected to the beam body 310.

[0124] refer to Figure 6 The side wall of the beam body 310 may be constructed with a first clearance hole 312, which is connected to the mounting cavity 311.

[0125] refer to Figure 8 The support 320 may further include a support body 322, a portion of which is located within the mounting cavity 311 and is fixedly connected to the connecting shaft 321. (See reference) Figure 6 Another part of the seat body 322 extends to the outside of the beam body 310 via the first clearance hole 312 and is fixedly connected to the door body 20 so that the beam body 310 can rotate relative to the door body 20 about the axis of the connecting shaft 321.

[0126] refer to Figure 8The flip beam 30 in this embodiment may further include a drive mechanism 330, which is disposed in the mounting cavity 311. The drive mechanism 330 is connected to the support 320 and drives the support 320 to rotate relative to the beam body 310. Since the support 320 is fixedly connected to the door body 20, when the drive mechanism 330 drives the support 320 to rotate, the support 320 cannot rotate relative to the door body 20, thus forcing the beam body 310 to rotate relative to the door body 20.

[0127] The beam body 310 can rotate relative to the door body 20 or the support 320 to a first position and a second position.

[0128] refer to Figure 3 , Figure 4 , Figure 8 and Figure 10 When the door 20 is in the closed state, the beam body 310 rotates to the first position, and the width direction of the beam body 310 is parallel to the width direction of the door 20.

[0129] refer to Figure 2 , Figure 5 , Figure 9 and Figure 11 When the door 20 is in the open state, the beam body 310 rotates to the second position, and the width direction of the beam body 310 is perpendicular to the width direction of the door 20.

[0130] In some possible implementations of the embodiments of this application, reference is made to Figure 8 The drive mechanism 330 may include a drive motor 331, which is disposed in the mounting cavity 311 and is fixedly connected to the beam body 310.

[0131] In the implementation where the beam body 310 includes a first beam shell 314 and a second beam shell 315, the drive motor 331 can be fixedly connected to either the first beam shell 314 or the second beam shell 315, such as... Figure 8 As shown, the drive motor 331 is fixedly connected to the first beam shell 314.

[0132] refer to Figure 10 The drive motor 331 may have an output shaft 332, which may extend along the height direction Z of the door body 20. The drive motor 331 drives the output shaft 332 to rotate around the axis of the output shaft 332. The output shaft 332 may be fixedly connected to the support 320 and drive the support 320 to rotate around the axis of the output shaft 332.

[0133] In the refrigerator of this embodiment, the beam body 310 is driven by the drive motor 331 to automatically achieve a flipping action relative to the door 20, without needing to rotate in coordination with the cabinet 10, thus reducing the noise generated by the rotation of the flipping beam 30 during the opening and closing of the door.

[0134] In some possible implementations of the embodiments of this application, reference is made to Figure 8 The drive mechanism 330 may also include a crank 333, a connecting rod 334, and a rocker arm 337 connected in sequence.

[0135] The crank 333 has a first end and a second end, which are located at opposite ends in the extending direction of the crank 333. The first end is fixedly connected to the output shaft 332.

[0136] The connecting rod 334 has a first connecting end and a second connecting end, which are located at opposite ends of the extending direction of the connecting rod 334. The first connecting end is hinged to the second handle end.

[0137] refer to Figure 10 The connecting rod 334 and the crank 333 can be hinged through a first pivot 335. The first pivot 335 can be inserted through the second handle end and the first connecting end, and both the connecting rod 334 and the crank 333 can rotate about the first pivot 335.

[0138] The rocker arm 337 has a first rod end and a second rod end. The first rod end and the second rod end are located at opposite ends of the rocker arm 337 in the extension direction. The first rod end is hinged to a second connecting end, and the second rod end is connected to a support 320 and drives the support 320 to rotate.

[0139] refer to Figure 10 The rocker arm 337 and the connecting rod 334 can be hinged together via a second pivot 336. The second pivot 336 can be inserted through the first rod end and the second connecting end, and both the rocker arm 337 and the connecting rod 334 can rotate about the second pivot 336.

[0140] refer to Figure 11 The second rod end and the support 320 can be fixedly connected by a fixed shaft 338. The axis of the fixed shaft 338 can be collinear with the first axis. The fixed shaft 338 can pass through the second rod end and the support 320, and the fixed shaft 338 is fixed to the second rod end and the support 320 respectively, so that the rocker arm 337, the fixed shaft 338 and the support 320 rotate synchronously around the axis of the fixed shaft 338.

[0141] refer to Figure 12 The center point of the output shaft 332 is marked as point A, the center point of the first pivot 335 is marked as point B (B1 or B2), the center point of the second pivot 336 is marked as point C (C1 or C2), and the center point of the fixed shaft 338 is marked as point D.

[0142] Figure 12 In the diagram, the black lines represent the shapes of the crank 333, connecting rod 334, and rocker arm 337 when the beam body 310 rotates to the first position; the red lines represent the shapes of the crank 333, connecting rod 334, and rocker arm 337 when the beam body 310 rotates to the second position.

[0143] Figure 12 When the beam body 310 rotates to the first position, the corresponding crank 333, connecting rod 334 and rocker arm 337 are in the form of AB2C2D; when the beam body 310 rotates to the second position, the corresponding reciprocating swing mechanism is in the form of AB1C1D.

[0144] Since the drive motor 331 is fixedly connected to the beam body 310, the position of the motor shaft axis relative to the beam body 310 remains unchanged. Therefore, the position of point A relative to the beam body 310 remains unchanged.

[0145] Since the support 320, or the connecting shaft 321, rotates in place relative to the beam body 310 around the axis of the connecting shaft 321, the axial position of the connecting shaft 321 is fixed relative to the beam body 310. Therefore, the position of point D is fixed relative to the beam body 310.

[0146] refer to Figure 12 When the beam body 310 rotates to the first position relative to the support 320, the first end of the rocker arm 337 is located at point C2, the second end of the crank 333 is located at point B2, AB2 represents the crank 333, B2C2 represents the connecting rod 334, and C2D represents the rocker arm 337.

[0147] refer to Figure 12 When the beam body 310 rotates to the second position relative to the support 320, the first end of the rocker arm 337 is located at point C1, the second end of the crank 333 is located at point B1, AB1 represents the crank 333, B1C1 represents the connecting rod 334, and C1D represents the rocker arm 337.

[0148] When the beam body 310 rotates from the first position to the second position, that is, when the first end of the rocker arm 337 rotates from C2 to C1 along the first trajectory T1, the second end of the crank 333 rotates from B2 to B1 along the second trajectory T2, and the angle through which the second end of the crank 333 rotates is the first angle α1.

[0149] When the beam body 310 rotates from the second position to the first position, that is, when the first end of the rocker arm 337 rotates from C1 to C2 along the first trajectory T1, the second end of the crank 333 rotates from B1 to B2 along the third trajectory T3. The angle through which the second end of the crank 333 rotates is the second angle α2. The sum of the second angle α2 and the first angle α1 is 360°.

[0150] As can be seen, during one door opening and closing process, the output shaft 332 of the drive motor 331 rotates clockwise one revolution, driving the crank 333 to rotate clockwise one revolution. The crank 333 drives the support 320 to complete one cycle of reciprocating oscillation from C2 to C1 and then from C1 to C2. This action path is repeated during the next door opening and closing process. During one door opening and closing process, the drive motor 331 does not need to switch the direction of the output shaft 332, reducing the wear and tear on the drive motor 331 and extending its service life.

[0151] In some possible implementations of the embodiments of this application, reference is made to Figure 8 The flip beam 30 also includes a guide member 340, which is slidably disposed on the beam body 310 along the width direction of the beam body 310. A first guide rail 341 and a second guide rail 342 are constructed on the guide member 340. The first guide rail 341 and the second guide rail 342 are arranged along the width direction of the beam body 310 and are connected. The first guide rail 341 is closer to the top of the beam body 310 than the second guide rail 342.

[0152] In some embodiments, reference Figure 13 The beam body 310 may be constructed with a groove 318, which extends along the width direction of the beam body 310. (Reference) Figure 13 and Figure 14 The guide member 340 is equipped with a slider 344, which is slidably disposed in the groove 318 so that the guide member 340 can slide relative to the beam body 310 along the width direction of the beam body 310.

[0153] In other embodiments, the guide member 340 may be configured with a groove extending along the width direction of the beam body 310. A slider may be configured on the beam body 310, which slides within the groove, so that the guide member 340 can slide relative to the beam body 310 along the width direction of the beam body 310.

[0154] refer to Figure 8 The tilting beam 30 also includes a transmission mechanism 350, which is connected to the support 320 and the guide member 340 respectively, so as to drive the guide member 340 to slide along the width direction of the beam body 310 when the support 320 rotates relative to the beam body 310.

[0155] In some embodiments, reference Figure 8 The guide member 340 may be constructed with a rack 343, which extends along the width direction of the beam body 310.

[0156] The transmission mechanism 350 can be a gear, which is fixedly connected to the support 320. The gear meshes with the rack 343. When the drive mechanism 330 is working, the beam body 310 rotates relative to the support 320. For ease of description, the beam body 310 is taken as the reference frame, that is, it is assumed that the beam body 310 is stationary. Then the support 320 rotates relative to the beam body 310, and the gear rotates with the support 320. Since the gear meshes with the rack 343, the gear drives the rack 343 to move along the width direction of the beam body 310, thereby driving the guide member 340 to move along the width direction of the beam body 310.

[0157] In other embodiments, the transmission mechanism 350 may include a cylindrical gear and a bevel gear. The axis of the cylindrical gear may be collinear with the axis of the support 320, and the cylindrical gear is fixedly connected to the support 320. The bevel gear is rotatably mounted on the beam body 310 along its own axis. The axis of the bevel gear may be along the width direction of the beam body 310, and the bevel gear meshes with the cylindrical gear. The bevel gear may be constructed with a threaded hole, the axis of which may be along the width direction of the beam body 310.

[0158] The guide member 340 may include a screw that passes through the threaded hole of the bevel gear and is threadedly connected to the bevel gear.

[0159] When the support 320 drives the cylindrical gear to rotate, the cylindrical gear meshes with the bevel gear, thus the cylindrical gear drives the bevel gear to rotate. When the bevel gear rotates, it drives the screw to move along the width direction of the beam body 310, thereby causing the guide member 340 to move along the width direction of the beam body 310.

[0160] In some possible implementations of the embodiments of this application, reference is made to Figure 2 and Figure 15 The housing 10 may be constructed with a guide groove 130, which may be located on the top wall of the storage compartment 111. When both doors 20 are closed, the guide groove 130 corresponds to the position of the two doors 20.

[0161] refer to Figure 8 The flip beam 30 also includes a locking structure 360, which is slidably disposed on the beam body 310 along the height direction Z of the beam body 310.

[0162] refer to Figure 8 The locking structure 360 ​​includes a locking member 365 located at the top, a portion of which can extend to the outside of the top of the beam body 310, and another portion of which is located within the mounting cavity 311.

[0163] refer to Figure 6A second clearance hole 313 may be constructed at the top of the beam body 310 in the height direction Z. The locking member 365 passes through the second clearance hole 313. When the door body 20 where the flip beam 30 is located is closed, the second clearance hole 313 is opposite to the guide groove 130.

[0164] The locking element 365 is used to slide into the guide groove 130. The locking structure 360 ​​is slidably disposed on the beam body 310 along the height direction Z of the beam body 310, so that when the door 20 where the flip beam 30 is located is closed, the locking element 365 extends upward into the guide groove 130 or moves downward out of the guide groove 130.

[0165] refer to Figure 8 The locking structure 360 ​​also includes a sliding member 361, which can be located in the mounting cavity 311 and is slidably disposed on the first guide rail 341 or the second guide rail 342.

[0166] refer to Figure 10 When the beam body 310 rotates to the first position relative to the support 320, the sliding member 361 slides in the first guide rail 341, and the height of the part of the locking member 365 extending outside the top of the beam body 310 is H1, where H1 is greater than 0.

[0167] refer to Figure 11 When the beam body 310 rotates to the second position relative to the support 320, the sliding member 361 slides in the second guide rail 342, and the height of the part of the locking member 365 extending outside the top of the beam body 310 is H2. H2 can be greater than 0, or H2 can be equal to 0 (the locking member 365 does not extend beyond the top of the beam body 310).

[0168] Since the first guide rail 341 is closer to the top of the beam body 310 than the second guide rail 342, H1 is greater than H2.

[0169] When the sliding member 361 slides on the first guide rail 341, the locking member 365 extends into the guide groove 130 to lock the position of the door body 20, reducing the possibility of the door body 20 being opened or loosened.

[0170] When the sliding member 361 slides onto the second guide rail 342, the locking member 365 moves downward out of the guide groove 130 to engage the locking of the door 20, making the door 20 easier to open.

[0171] In the refrigerator of this embodiment, the drive mechanism 330 drives the support 320 to rotate relative to the beam body 310, so that the beam body 310 automatically rotates to a first position when the door 20 is closed and automatically rotates to a second position when the door 20 is open. The beam body 310 is driven by the drive motor 331 to automatically achieve the flipping action relative to the door 20, without the need for rotation in coordination with the cabinet 10 guide, thus reducing the noise generated by the rotation of the flipping beam 30 during the opening and closing of the door.

[0172] Furthermore, when the beam body 310 rotates relative to the support 320, for ease of description, the beam body 310 is used as a reference. When the support 320 rotates relative to the beam body 310, the transmission mechanism 350 drives the guide member 340 to slide. When the beam body 310 rotates to the first position, the sliding member 361 slides onto the first guide rail 341, and the locking member 365 automatically extends into the guide groove 130 to lock the position of the door 20, making it difficult for the door 20 to be accidentally opened or loosened. When the beam body 310 rotates to the second position, the sliding member 361 slides onto the second guide rail 342, and the locking member 365 moves downward out of the guide groove 130 to facilitate opening the door 20. Since the beam body 310 is flipped by the drive mechanism 330, and when the beam body 310 is flipped, the locking structure 360 ​​is automatically raised and lowered by the transmission mechanism 350 and the guide member 340, the flipping action of the beam body 310 does not need to rely on the rigid collision between the guide member 340 and the guide groove 130 to guide the flipping action of the beam body 310, which reduces the possibility of the guide member 340 colliding with the groove wall of the guide groove 130, thereby reducing the noise generated by the refrigerator during the opening and closing of the door.

[0173] In some possible implementations of the embodiments of this application, the first guide rail 341 and the second guide rail 342 may extend along the width direction of the beam body 310, respectively.

[0174] The first guide rail 341 and the second guide rail 342 extend along the width direction of the beam body 310, so that when the sliding member 361 is slidably mounted on the first guide rail 341 or the second guide rail 342, the sliding member 361 is not easily displaced within the first guide rail 341 or the second guide rail 342 under the action of the self-weight of the locking structure 360. This allows the sliding member 361 to remain within the first guide rail 341 or the second guide rail 342 when the drive mechanism 330 is not working, thereby maintaining the height of the portion of the locking member 365 extending outside the top of the beam body 310.

[0175] refer to Figure 8 and Figure 14A transition guide rail 345 may also be constructed on the guide member 340. The transition guide rail 345 is located between the first guide rail 341 and the second guide rail 342, and its two ends are connected to the first guide rail 341 and the second guide rail 342, respectively. The distance between the transition guide rail 345 and the top end of the beam body 310 increases from the end closer to the first guide rail 341 to the end closer to the second guide rail 342.

[0176] The transition guide rail 345 is connected between the first guide rail 341 and the second guide rail 342, and the transition guide rail 345 makes it easier for the slider 361 to move between the first guide rail 341 and the second guide rail 342.

[0177] In some possible implementations of the embodiments of this application, reference is made to Figure 14 The transition guide 345 can extend along a curve. For example, the transition guide 345 can include multiple arc segments to make the transition guide 345 smoother, so that the movement direction of the slider 361 within the transition guide 345 changes slowly, reducing the friction between the slider 361 and the transition guide 345, and making the slider 361 slide more smoothly along the transition guide 345.

[0178] In some possible implementations of the embodiments of this application, the first guide rail 341 may be a first guide hole extending along the width direction of the beam body 310.

[0179] The second guide rail 342 can be a second guide hole extending along the width direction of the beam body 310.

[0180] The guide member 340 may include a connecting plate 346, on which a first guide hole and a second guide hole are formed.

[0181] The sliding member 361 is slidably disposed in the first guide hole or the second guide hole.

[0182] The first and second guide holes have simple structures, are easy to process and manufacture, and improve the production efficiency of the flip beam 30.

[0183] In some possible implementations of the embodiments of this application, reference is made to Figure 13 The sliding member 361 may include a sliding portion 362, which may be rod-shaped, and the axis of the sliding portion 362 may be along the thickness direction of the beam body 310. The sliding member 361 is slidably disposed in the first guide hole or the second guide hole.

[0184] The sliding part 362 extends to the outside of the connecting plate 346 at both ends along the thickness direction of the connecting plate 346.

[0185] refer to Figure 13The sliding member 361 may also include a first stop portion 363, which may be block-shaped. The first stop portion 363 is connected to one end of the sliding member 362 along the thickness direction of the connecting plate 346 and is used to cooperate with the plate surface stop of the connecting plate 346 so that the end of the sliding member 362 connected to the first stop portion 363 is not easy to come out of the first guide hole or the second guide hole.

[0186] refer to Figure 13 The sliding member 361 may also include a second stop portion 364, which may be block-shaped. The second stop portion 364 is connected to the other end of the sliding member 362 along the thickness direction of the connecting plate 346 and is used to cooperate with the plate surface stop of the connecting plate 346 so that the end of the sliding member 362 connected to the second stop portion 364 is not easy to come out of the first guide hole or the second guide hole.

[0187] In some possible implementations of the embodiments of this application, reference is made to Figure 8 The locking structure 360 ​​may further include a connector 366, which may be a connecting column or a connecting rod, etc. The connector 366 extends along the height direction Z of the beam body 310. The connector 366 is slidably disposed on the beam body 310.

[0188] refer to Figure 8 and Figure 10 The tilting beam 30 may further include a second bracket 317, which is located within the mounting cavity 311 and is fixedly connected to the beam body 310. A second limiting hole 319 may be constructed on the second bracket 317, with the axis of the second limiting hole 319 along the height direction Z of the beam body 310. A connecting member 366 is movably inserted into the second limiting hole 319. The second limiting hole 319 can limit the connecting member 366, allowing it to swing relative to the axis of the second limiting hole 319.

[0189] The top end of connector 366 is connected to locking member 365, and the bottom end of connector 366 is connected to sliding member 361.

[0190] In the implementation of the slider 361 including the first stop 363 and the second stop 364, the bottom end of the connector 366 can be connected to the first stop 363 or the second stop 364.

[0191] The locking member 365 and the sliding member 361 are connected by the connecting member 366 so that the sliding member 361 drives the locking member 365 to move synchronously along the height direction Z of the beam body 310 during the sliding process along the first guide rail 341 and the second guide rail 342.

[0192] There can be multiple second supports 317, and multiple second supports 317 can be arranged at Z intervals along the height direction of the beam body 310.

[0193] refer to Figure 10 The tilting beam 30 may also include a support rod 3110, which is connected to the bottom end of the locking member 365. The second bracket 317 at the top may be configured with a third limiting hole 3112, the axis of which extends along the height direction Z of the beam body 310. The support rod 3110 is movably inserted into the third limiting hole 3112.

[0194] The support rod 3110 can further limit the locking member 365, making it less likely for the locking member 365 to swing relative to the axis of the connecting member 366, improving the fitting accuracy between the locking member 365 and the guide groove 130, and making it less likely for the locking member 365 to collide with the groove wall of the guide groove 130, thereby reducing the noise generated by the refrigerator during the opening and closing of the door.

[0195] refer to Figure 10 The flip beam 30 may also include a second elastic element 3111, which may be a spring or other elastic component. The second elastic element 3111 may be sleeved on the support rod 3110. The second elastic element 3111 is used to apply an upward elastic force to the locking member 365 when the sliding member 361 slides in the second guide rail 342, so that the sliding member 361 can move more easily into the second guide rail 342 during the process of moving from the second guide rail 342 to the first guide rail 341.

[0196] In some possible implementations of the embodiments of this application, reference is made to Figure 13 and Figure 16 The flip beam 30 may also include a limiting mechanism 370, which is used to limit the flip position of the beam body 310 when the door 20 is opened, thereby reducing the possibility that the flip angle of the beam body 310 is too large.

[0197] The following is for reference Figure 16 The structure of the limiting mechanism 370 is described.

[0198] The limiting mechanism 370 may include a connecting seat 371, which is connected to the beam body 310. The connecting seat 371 is provided with a connecting hole 372, which faces the support 320.

[0199] The limiting mechanism 370 may also include a telescopic block 373, which is telescopically disposed on the connecting seat 371, and a portion of the telescopic block 373 extends outside the connecting hole 372; the portion of the telescopic block 373 extending outside the connecting hole 372 has a guide surface 374 and a limiting surface 375, and the guide surface 374 and the limiting surface 375 are respectively located on opposite sides of the telescopic block 373 along the width direction of the beam body 310.

[0200] The connecting seat 371 is constructed with a stop surface 377, which is opposite to the limiting surface 375, and a limiting region 378 is formed between the stop surface 377 and the limiting surface 375.

[0201] The limiting mechanism 370 may further include a first elastic element 376, which may be a spring or other elastic component. The first elastic element 376 is disposed between the connecting seat 371 and the telescopic block 373, and the first elastic element 376 is used to apply elastic force to the telescopic block 373 so that the telescopic block 373 and the connecting seat 371 stop engagement.

[0202] The support 320 may be constructed with a stop protrusion 323.

[0203] In the implementation of the support 320 including the connecting shaft 321, the stop protrusion 323 can be constructed on the outer wall of the connecting shaft 321, and the stop protrusion 323 protrudes from the outer wall of the connecting shaft 321.

[0204] During the process of the beam body 310 rotating from the first position to the second position, the stop protrusion 323 slides along the guide surface 374 to the limiting surface 375, and moves to the limiting area 378 when the beam body 310 rotates to the second position.

[0205] When the stop protrusion 323 moves to the limiting area 378, the stop surface 377 stops the stop protrusion 323 to restrict the stop protrusion 323 from continuing to rotate away from the guide surface 374, thereby limiting the flipping position of the beam body 310 when the door 20 is opened, and reducing the possibility that the flipping angle of the beam body 310 is too large.

[0206] As the door 20 gradually closes from the open state, the support 320 rotates relative to the beam body 310 toward the guide surface 374, the stop protrusion 323 presses against the limiting surface 375, and passes over the telescopic block 373. When the stop protrusion 323 separates from the guide surface 374, the telescopic block 373 returns to its original position under the action of the first elastic element 376.

[0207] In some possible implementations of this application, the slope of the guide surface 374 relative to the width direction of the beam body 310 is less than the slope of the limiting surface 375 relative to the width direction of the beam body 310, so that the beam body 310 can more easily cross the guide surface 374 during the process of flipping from the first position to the second position, thereby flipping with less resistance.

[0208] The slope of the limiting surface 375 is relatively large so that when the beam body 310 is in the second position, it is not easy for the beam body 310 to overturn when it is accidentally touched, so that the beam body 310 can be kept in the second position.

[0209] This application embodiment also provides a refrigerator, which differs from the refrigerator in the preceding embodiments in that: the guide member 340 includes a sliding member. The bottom of the locking structure 360 ​​is constructed with a first guide rail and a second guide rail, the first guide rail being farther away from the top of the beam body 310 than the second guide rail.

[0210] When the beam body 310 rotates to the first position, the width direction of the beam body 310 is parallel to the width direction of the door body 20, the sliding member slides on the first guide rail, and the locking member 365 extends into the guide groove 130.

[0211] When the beam body 310 rotates to the second position, the width direction of the beam body 310 is perpendicular to the width direction of the door body 20, the sliding member slides on the second guide rail, and the locking member 365 moves downward out of the guide groove 130.

[0212] When the sliding member slides on the first guide rail, the locking member 365 extends into the guide groove 130 to lock the position of the door 20, reducing the possibility of the door 20 being opened or loosened.

[0213] When the sliding member slides onto the second guide rail, the locking member 365 moves downward out of the guide groove 130 to engage the locking of the door 20, making the door 20 easier to open.

[0214] In the refrigerator of this embodiment, the drive mechanism 330 drives the support 320 to rotate relative to the beam body 310, so that the beam body 310 automatically rotates to a first position when the door 20 is closed and automatically rotates to a second position when the door 20 is open. The beam body 310 is driven by the drive motor 331 to automatically achieve the flipping action relative to the door 20, without the need for rotation in coordination with the cabinet 10 guide, thus reducing the noise generated by the rotation of the flipping beam 30 during the opening and closing of the door.

[0215] Furthermore, when the beam body 310 rotates relative to the support 320, for ease of description, the beam body 310 is used as a reference. When the support 320 rotates relative to the beam body 310, the transmission mechanism 350 drives the guide member 340 to slide. When the beam body 310 rotates to the first position, the sliding member slides onto the first guide rail, and the locking member 365 automatically extends into the guide groove 130 to lock the position of the door 20, making it difficult for the door 20 to be accidentally opened or loosened. When the beam body 310 rotates to the second position, the sliding member slides onto the second guide rail, and the locking member 365 moves downward out of the guide groove 130 to facilitate opening the door 20. Since the beam body 310 is flipped by the drive mechanism 330, and when the beam body 310 is flipped, the locking structure 360 ​​is automatically raised and lowered by the transmission mechanism 350 and the guide member 340, the flipping action of the beam body 310 does not need to rely on the rigid collision between the guide member 340 and the guide groove 130 to guide the flipping action of the beam body 310, which reduces the possibility of the guide member 340 colliding with the groove wall of the guide groove 130, thereby reducing the noise generated by the refrigerator during the opening and closing of the door.

[0216] In some possible implementations of this application, the refrigerator may further include a sensor switch disposed on the cabinet 10, which is used to detect the distance between itself and the tilting beam 30. The sensor switch may be disposed on the top wall of the storage compartment 111, and close to the front wall of the cabinet 10.

[0217] The inductive switch can be a capacitive inductive switch or an ultrasonic inductive switch, etc. The inductive switch is used to detect the distance between itself and the locking element 365.

[0218] The refrigerator may also include a controller, which is electrically connected to a sensor switch, and the controller is configured to:

[0219] When the distance detected by the inductive switch gradually decreases to the first preset distance, the control output shaft 332 rotates by a second angle α2.

[0220] When the distance detected by the inductive switch gradually increases to the second preset distance, the control output shaft 332 rotates by the first angle α1.

[0221] When the distance detected by the sensor switch gradually decreases, it indicates that the door 20 is gradually closing. When the distance detected by the sensor switch decreases to a first preset distance, it indicates that the tilting beam 30 is close to the front of the housing 10, and at this position, after the drive motor 331 rotates by a second angle α2, the tilting beam 30 can rotate to the first position.

[0222] As the distance detected by the sensor switch gradually increases, it indicates that the door 20 is gradually opening. When the distance detected by the sensor switch decreases to a second preset distance, the drive motor 331 is controlled to rotate by a first angle α1, and the tilting beam 30 can rotate to the second position.

[0223] The controller controls the timing of the start of rotation of the drive motor 331 based on the distance between itself and the flip beam 30 detected by the inductive switch, thereby reducing the possibility of interference between the door 20 where the flip beam 30 is located and another door 20, and improving the automation level of the flip beam 30's flipping action.

[0224] When the distance detected by the inductive switch decreases to the first preset distance, the locking member 365 just slides into the guide groove 130. At this time, after the drive motor 331 rotates to the second angle α2, the flip beam 30 can rotate to the first position, and the locking member 365 gradually extends into the guide groove 130.

[0225] When the distance detected by the induction switch decreases to the second preset distance, the locking member 365 moves out of the guide groove 130 by a small part, and there is a tendency to open the door. At this time, after controlling the drive motor 331 to rotate the first angle α1, the flip beam 30 can rotate to the second position, and the locking member 365 gradually moves out of the guide groove 130.
