Description

Technical Field

[0001] This invention relates to the field of refrigerator and freezer technology, and in particular to a refrigerator. Background Technology

[0002] Existing multi-door refrigerators typically feature a hinged beam in the middle of the cabinet to enhance structural strength and ensure proper operation. However, while these refrigerators have multiple doors, the hinged beam is usually only fixedly connected to one door. When a user opens the door with the fixed beam, it is pulled away from the cabinet. Conversely, when opening a door not fixed to the beam, the beam remains in its original position, obstructing the drawer opening. This interference prevents users from pulling out larger drawers, forcing them to repeatedly open the door with the beam. This cumbersome process results in a poor user experience. Furthermore, frequent door openings cause cold air leakage, disrupting internal temperature stability and wasting electricity. Summary of the Invention

[0003] The purpose of this invention is to provide a refrigerator in which a flip beam is connected to a first door or a second door and can be pulled away from the refrigerator body when either door is opened. The user only needs to open one side door to take out the drawers inside the refrigerator. At the same time, the movement of the flip beam will not affect the other door or other components inside the refrigerator. The refrigerator has a clever structural design, is easy to operate, and provides a good user experience.

[0004] To achieve the above objectives, the present invention provides a refrigerator, comprising a cabinet, a first door, a second door, and a flip beam. The first door and the second door are located on the front side of the cabinet and hinged to the cabinet. The flip beam is located inside the cabinet and behind the first door and the second door.

[0005] The top surface of the tilting beam is provided with an arc-shaped guide groove, which includes a first long groove, a first short groove, a second short groove, and a second long groove. One end of the first long groove and the second long groove extends outward from the box body and reaches the edge of the tilting beam. The other end of the first long groove is connected to the first short groove, and the other end of the second long groove is connected to the second short groove. The centers of the first long groove and the second short groove coincide with the hinge axis of the second box door, and the centers of the first short groove and the second long groove coincide with the hinge axis of the first box door.

[0006] The first door is provided with a first guide rod and a first fixing block, and the second door is provided with a second guide rod and a second fixing block. The first guide rod can slide in the first long groove and the first short groove, and the second guide rod can slide in the second short groove and the second long groove. The first fixing block and the second fixing block are used to support the flip beam.

[0007] In some embodiments of this application, a mounting base is further included. The mounting base is disposed inside the housing and located below the tilting beam. The mounting base is provided with an arc-shaped sliding groove and a stop groove. The arc-shaped sliding groove includes a first sliding groove and a second sliding groove. One end of the first sliding groove and the second sliding groove communicates with the stop groove. The other end of the first sliding groove and the second sliding groove extends outward from the housing and reaches the edge of the mounting base. A ball bearing is embedded in the bottom of the tilting beam. The ball bearing can roll in the first sliding groove and the second sliding groove. The stop groove matches the ball bearing.

[0008] In some embodiments of this application, the first guide rod and the second guide rod are movable rods that can move up and down along their own axes.

[0009] In some embodiments of this application, the first guide rod and the second guide rod are telescopic rods with adjustable lengths, the bottom ends of the first guide rod and the second guide rod are rounded, and the edge of the flip beam connecting the first long groove and the second long groove forms a transition portion that contacts the first guide rod and the second guide rod, the transition portion being a downwardly sloping surface.

[0010] In some embodiments of this application, the flipping beam is provided with a first fixed rod and a second fixed rod that can move in the vertical direction. The first fixed rod is located above the first fixed block and abuts against the first fixed block. The second fixed rod is located above the second fixed block and abuts against the second fixed block. The first fixed block is provided with a first fixed hole, and the first fixed rod can fall into the first fixed hole as the first box door rotates. The second fixed block is provided with a second fixed hole, and the second fixed rod can fall into the second fixed hole as the second box door rotates.

[0011] In some embodiments of this application, a first spring is sleeved on the first fixing rod, and the first fixing rod can abut against the first fixing block under the action of the first spring; a second spring is sleeved on the second fixing rod, and the second fixing rod can abut against the second fixing block under the action of the second spring.

[0012] In some embodiments of this application, the flip beam is provided with a first fixing plate for setting the first fixing rod, a first washer is fixedly connected to the first fixing rod, and the two ends of the first spring abut against the first fixing plate and the first washer respectively. The flip beam is also provided with a second fixing plate for setting the second fixing rod, a second washer is fixedly connected to the second fixing rod, and the two ends of the second spring abut against the second fixing plate and the second washer respectively.

[0013] In some embodiments of this application, the flipping beam includes a beam body and a guide block sleeved on the top of the beam body. The guide block is connected to the beam body, and the first long groove, the first short groove, the second short groove, and the second long groove are all provided on the guide block.

[0014] In some embodiments of this application, the beam body includes a front cover plate and a rear cover plate, wherein the front cover plate is connected to the rear cover plate.

[0015] In some embodiments of this application, a support groove is provided in the middle of the front cover plate, and the first fixing block and the second fixing block are located in the support groove when the first box door and the second box door are closed.

[0016] Compared with the prior art, the refrigerator of the present invention has the following advantages:

[0017] Before use, open the first and second boxes and assemble the tilting beam. Then close the first and second boxes. At this time, the first guide rod is located at the connection between the first long slot and the first short slot, and the second guide rod is located at the connection between the second short slot and the second long slot. When in use, the user opens the first box, and the first box rotates around the hinge axis. The first guide rod also rotates around the hinge axis with the rotation of the first box. Since the centers of the first short slot and the second long slot coincide with the hinge axis of the first box, the first guide rod slides along the first short slot and reaches the end of the first short slot. At this time, the first guide rod abuts against the tilting beam and drives the tilting beam to rotate together. During the movement of the tilting beam, the second guide rod on the second box moves along the second long slot. The groove slides and eventually slides off the edge of the flip beam. Throughout the process, the second guide rod does not affect the movement of the flip beam. Then, dragged by the first guide rod, the flip beam gradually leaves the box and finally lands on the first fixed block. The first guide rod and the first fixed block fix the flip beam, one above the other. The flip beam connected to the first box door further leaves the box as the first box door rotates. At this time, the opening of the box door is no longer blocked by the flip beam, and the drawer inside the box is no longer interfered with by the flip beam. The drawer can be pulled out or pushed back normally. At the same time, the position of the second box door will not change due to the movement of the flip beam, and the movement of the flip beam will not affect other components. Similarly, when the user opens the second door, the second door rotates around its hinge axis, and the second guide rod also rotates around the hinge axis along with the second door. Since the centers of the second short groove and the first long groove coincide with the hinge axis of the second door, the second guide rod slides along the second short groove and reaches its end. At this point, the second guide rod abuts against the flip beam and drives the flip beam to rotate together. During the movement of the flip beam, the first guide rod on the first door slides along the first long groove and eventually slides out of the flip beam from its edge. Throughout the entire process, the first guide rod will not interfere with the flip beam. The movement of the first door causes no impact. The flip beam, dragged by the second guide rod, gradually leaves the refrigerator body and finally rests on the second fixed block. The second guide rod and the second fixed block, positioned one above the other, fix the flip beam in place. The flip beam connected to the second door then further leaves the refrigerator body as the second door rotates. At this point, the opening of the door is no longer obstructed by the flip beam, and the drawers inside the refrigerator are not interfered with. The drawers can be pulled out or pushed back normally. Simultaneously, the position of the first door remains unchanged due to the movement of the flip beam, and its movement does not affect other components. Thus, the refrigerator's flip beam is connected to either the first or second door and can be pulled away from the refrigerator body when either door is opened. Users only need to open one door to remove the drawers inside. Furthermore, the movement of the flip beam does not affect the other door or other components inside the refrigerator. This refrigerator features a clever structural design, is easy to operate, and provides a good user experience. Attached Figure Description

[0043] Please refer to Figure 1 - Figure 14 This invention provides a refrigerator, comprising a body 1, a first door 2, a second door 3, and a flip beam 4. Specifically, the body 1 has an opening on its front side. The first door 2 and the second door 3 are located at the opening on the front side of the body 1 and are hinged to the body 1. The flip beam 4 is also located at the opening on the front side of the body 1 and is positioned behind the first door 2 and the second door 3. More precisely, the flip beam 4 is located behind the connection between the first door 2 and the second door 3. To more accurately describe the position of the flip beam 4, the location of the first door 2 and the second door 3 in this application is defined as the front of the refrigerator, and the location of the body 1 is defined as the rear of the refrigerator. Further, as... Figure 7 As shown, the top surface of the tilting beam 4 is provided with an arc-shaped guide groove, which includes a first long groove 411, a first short groove 412, a second short groove 413, and a second long groove 414. One end of the first long groove 411 and the second long groove 414 extend towards the positions of the first door 2 and the second door 3, respectively, and reaches the edge of the tilting beam 4. The other end of the first long groove 411 is connected to the first short groove 412, and the other end of the second long groove 414 is connected to the second short groove 413. It should also be noted that the first long groove 411 and the second short groove 413... The center of the first short groove 412 and the center of the second long groove 414 coincide with the hinge axis of the first door 2; furthermore, the first door 2 is provided with a first guide rod 21 and a first fixing block 22, and the second door 3 is provided with a second guide rod 31 and a second fixing block 32. The first guide rod 21 can slide in the first long groove 411 and the first short groove 412, and the second guide rod 31 can slide in the second short groove 413 and the second long groove 414. The first fixing block 22 and the second fixing block 32 are used to support the flip beam 4.

[0044] Based on the above structure, before use, the first box door 2 and the second box door 3 are opened to assemble the flip beam 4, and then the first box door 2 and the second box door 3 are closed. At this time, the first guide rod 21 is located at the connection between the first long groove 411 and the first short groove 412, and the second guide rod 31 is located at the connection between the second short groove 413 and the second long groove 414. When in use, the user opens the first box door 2, and the first box door 2 rotates around the hinge axis. The first guide rod 21 also rotates around the hinge axis with the rotation of the first box door 2. Since the center of the first short groove 412 and the second long groove 414 coincides with the hinge axis of the first box door 2, the first guide rod 21 slides along the first short groove 412 and reaches the end of the first short groove 412. At this time, the first guide rod 21 abuts against the flip beam 4 and drives the flip beam 4 to rotate together. During the movement of the flip beam 4, the second box door 3... The second guide rod 31 slides along the second long groove 414 and eventually slides out of the flip beam 4 from the edge. During the whole process, the second guide rod 31 will not affect the movement of the flip beam 4. Then, the flip beam 4 gradually leaves the box 1 under the drag of the first guide rod 21 and finally falls on the first fixing block 22. The first guide rod 21 and the first fixing block 22 fix the flip beam 4 from above and below. The flip beam 4 connected to the first box door 2 further leaves the box 1 as the first box door 2 rotates. At this time, the opening of the box door is no longer blocked by the flip beam 4, and the drawer inside the box 1 is no longer interfered with by the flip beam 4. The drawer can be pulled out or pushed back normally. At the same time, the position of the second box door 3 will not change due to the movement of the flip beam 4. The movement of the flip beam 4 will not affect other components. Similarly, when the user opens the second door 3, the second door 3 rotates around the hinge axis, and the second guide rod 31 also rotates around the hinge axis along with the rotation of the second door 3. Since the centers of the second short groove 413 and the first long groove 411 coincide with the hinge axis of the second door 3, the second guide rod 31 slides along the second short groove 413 and reaches the end of the second short groove 413. At this time, the second guide rod 31 abuts against the flip beam 4 and drives the flip beam 4 to rotate together. During the movement of the flip beam 4, the first guide rod 21 on the first door 2 slides along the first long groove 411 and finally slides out of the flip beam 4 from the edge of the flip beam 4. Throughout the process, the first guide rod 21 moves along the first long groove 411 and eventually slides out of the flip beam 4. This will not affect the movement of the flip beam 4. Subsequently, the flip beam 4 gradually leaves the box 1 under the drag of the second guide rod 31 and finally falls on the second fixing block 32. The second guide rod 31 and the second fixing block 32 fix the flip beam 4 from above and below. The flip beam 4 connected to the second box door 3 further leaves the box 1 as the second box door 3 rotates. At this time, the opening of the box door is no longer blocked by the flip beam 4. The drawer inside the box 1 will also not be interfered with by the flip beam 4. The drawer can be pulled out or pushed back normally. At the same time, the position of the first box door 2 will not change due to the movement of the flip beam 4. The movement of the flip beam 4 will not affect other components.In this way, the refrigerator's flip beam 4 is connected to the first door 2 or the second door 3 and can be taken away from the cabinet 1 when either door is opened. The user only needs to open one side door to take out the drawer inside the cabinet. At the same time, the movement of the flip beam 4 will not affect the other door or other parts inside the cabinet 1. The refrigerator has a clever structural design, is easy to operate, and provides a good user experience.

[0045] For further details, please refer to... Figure 6 , Figure 12 and Figure 14 The refrigerator of this application also includes a mounting base 5, which is located inside the cabinet 1 and below the flip beam 4. The mounting base 5 is provided with an arc-shaped sliding groove and a stop groove 53. The arc-shaped sliding groove includes a first sliding groove 51 and a second sliding groove 52. One end of the first sliding groove 51 and the second sliding groove 52 are connected to the stop groove 53. The other end of the first sliding groove 51 and the second sliding groove 52 extends toward the location of the first cabinet door 2 and the second cabinet door 3 and reaches the edge of the mounting base 5. Corresponding to the first sliding groove 51, the second sliding groove 52 and the stop groove 53, a ball bearing 423 is embedded in the bottom of the flip beam 4. The ball bearing 423 can roll in the first sliding groove 51 and the second sliding groove 52. At the same time, the size of the stop groove 53 matches the ball bearing 423. Based on the above structure, when the tilting beam 4 is assembled, the ball bearing 423 falls into the stop groove 53. When the tilting beam 4 is fixed in the housing 1, the mounting base 5 can fix and support the tilting beam 4 to prevent it from running. When the tilting beam 4 rotates with the first door 2 or the second door 3, the ball bearing 423 falls from the stop groove 53 into the first slide groove 51 or the second slide groove 52. At this time, the ball bearing 423 can roll or slide in the first slide groove 51 or the second slide groove 52 with the rotation of the tilting beam 4, reducing the friction between the tilting beam 4 and the mounting base 5, and ensuring that the tilting beam 4 can leave the mounting base 5 as soon as possible.

[0046] For the tilting beam 4 of this application, after it leaves the housing 1 with the first door 2 or the second door 3, it still needs to return to the housing 1 and fall back onto the mounting base 5 as the first door 2 or the second door 3 rotates. Therefore, when the tilting beam 4 returns to the mounting base 5, the first guide rod 21 or the second guide rod 31 that left the tilting beam 4 before it needs to re-enter the first long slot 411 or the second long slot 414. The user can of course choose to reassemble the first guide rod 21 using the first long slot 411 or the second guide rod 31 using the second long slot 414, but this operation requires multiple movements and adjustments of the tilting beam 4, and the whole operation process is too cumbersome, which is not conducive to improving the user's operating experience. Therefore, in order to simplify the assembly process of the first guide rod 21 and the second guide rod 31, the first guide rod 21 and the second guide rod 31 of this application are set as movable rods that can move up and down along their own axis. During assembly, the user can first operate the first guide rod 21 and the second guide rod 31 to lift them up until the entire first guide rod 21 and the second guide rod 31 reach above the flip beam 4. At this time, the first guide rod 21 and the second guide rod 31 no longer interfere with the flip beam 4, and the flip beam 4 can be freely installed into the box 1. The first box door 2 and the second box door 3 can also be freely rotated and the box 1 closed. After the flip beam 4, the first box door 2 and the second box door 3 reach the designated position, the user operates the first guide rod 21 and the second guide rod 31 to sink again. The first guide rod 21 returns to the first long groove 411 and the first short groove 412, and the second guide rod 31 returns to the second short groove 413 and the second long groove 414.

[0047] Of course, regarding the first guide rod 21 and the second guide rod 31 of this application, they are respectively set on the top of the first box door 2 and the second box door 3. Although the above structure can realize the normal assembly of the flip beam 4, the first box door 2 and the second box door 3, it is inevitable that the operation will be inconvenient due to the high position of the first guide rod 21 and the second guide rod 31. Therefore, in order to realize the automatic storage of the first guide rod 21 and the second guide rod 31, the first guide rod 21 and the second guide rod 31 of this application are set as telescopic rods with adjustable length. At the same time, the bottom ends of the first guide rod 21 and the second guide rod 31 are rounded. The edge of the flip beam 4 connecting the first long groove 411 and the second long groove 414 forms a transition part 415 that contacts the first guide rod 21 and the second guide rod 31. The transition part 415 is a downward inclined surface. Based on the above structure, the flip beam 4 is assembled first during use. After the flip beam 4 is assembled, the first box door 2 and the second box door 3 are closed directly. At this time, the first guide rod 21 and the second guide rod 31 approach the flip beam 4 under the rotation of the first box door 2 and the second box door 3 and abut against the transition part 415 at a certain moment. Since the transition part 415 is set with an inclined surface and the bottom ends of the first guide rod 21 and the second guide rod 31 are rounded, the first guide rod 21 and the second guide rod 31 are gradually shortened under the push of the inclined surface of the transition part 415. After the first guide rod 21 and the second guide rod 31 pass the transition part 415, the bottom ends of the first guide rod 21 and the second guide rod 31 abut against the top surface of the flip beam 4. As the first box door 2 and the second box door 3 continue to rotate, the first guide rod 21 and the second guide rod 31 eventually reach the top of the first long groove 411 and the first short groove 412, as well as the second short groove 413 and the second long groove 414. At this time, the first guide rod 21 and the second guide rod 31 extend into the groove again, realizing the normal closing of the first box door 2 and the second box door 3. Thus, the structural design of the first guide rod 21 and the second guide rod 31 is equally precise and ingenious, which can effectively improve the user experience.

[0048] Furthermore, due to the arrangement of the first fixing block 22 and the second fixing block 32, after the tilting beam 4 leaves the mounting base 5, it rests on the first fixing block 22 or the second fixing block 32, which supports the tilting beam 4 to ensure its normal movement. However, in actual operation, the designers found that because the tilting beam 4 needs to rotate with the first door 2 or the second door 3, the current structure still has a certain probability of causing the tilting beam 4 to slip off the first fixing block 22 or the second fixing block 32. Therefore, in order to strengthen the connection between the first fixing block 22 and the second fixing block 32 and the tilting beam 4, and to ensure the stability of the tilting beam 4 on the first door 2 or the second door 3, please refer to... Figure 3 - Figure 6 , Figure 11 - Figure 13The flip beam 4 in this application is also provided with a first fixing rod 44 and a second fixing rod 45 that can move up and down along its own axis in the vertical direction. The first fixing rod 44 is located above the first fixing block 22 and abuts against the first fixing block 22. The second fixing rod 45 is located above the second fixing block 32 and abuts against the second fixing block 32. Corresponding to the above fixing rods, the first fixing block 22 is provided with a first fixing hole 221. The first fixing rod 44 can fall into the first fixing hole 221 as the first box door 2 rotates. The second fixing block 32 is provided with a second fixing hole 321. The second fixing rod 45 can fall into the second fixing hole 321 as the second box door 3 rotates. Based on the above structure, when the first door 2 rotates, the first fixing block 22 moves together with the first door 2. The designer chose to set the first fixing hole 221 on the movement path of the first fixing block 22. When the first fixing block 22 moves, the first fixing rod 44 can fall into the first fixing hole 221 at a certain moment. Due to the gravity of the first fixing rod 44, the first fixing rod 44 that falls into the first fixing hole 221 will not come out of the first fixing hole 221. That is, the first fixing block 22 is fixedly connected to the first fixing rod 44 through the first fixing hole 221, which can significantly strengthen the connection effect between the first fixing block 22 and the flip beam 4, ensure the stability of the flip beam 4 on the first fixing block 22, and prevent the flip beam 4 from slipping. Similarly, when the second door 3 rotates, the second fixing block 32 moves together with the second door 3. The designers chose to set the second fixing hole 321 on the movement path of the second fixing block 32. When the second fixing block 32 moves, the second fixing rod 45 can fall into the second fixing hole 321 at a certain moment. Due to the gravity of the second fixing rod 45, the second fixing rod 45 that falls into the second fixing hole 321 will not come out of the second fixing hole 321. That is, the second fixing block 32 achieves a fixed connection with the second fixing rod 45 through the second fixing hole 321. This can also significantly enhance the connection effect between the second fixing block 32 and the flip beam 4, ensure the stability of the flip beam 4 on the second fixing block 32, and prevent the flip beam 4 from slipping.

[0049] Furthermore, relying solely on the gravity of the first fixing rod 44 is insufficient to guarantee its accurate and stable insertion into the first fixing hole 221; the same applies to the second fixing rod 45. Therefore, to ensure the effective use of the first fixing rod 44 and the second fixing rod 45, please refer to... Figure 12 and Figure 13A first spring 46 is fitted onto the first fixing rod 44. One end of the first spring 46 abuts against the first fixing plate of the first fixing rod 44, and the other end abuts against the first washer 48, which is also fitted onto the first fixing rod 44. The first washer 48 is fixedly connected to the first fixing rod 44, and the first fixing rod 44 abuts against the first fixing block 22 under the elastic force of the first spring 46. Thus, when the first fixing rod 44 reaches above the first fixing hole 221, it enters the first fixing hole 221 under the combined action of its own weight and the elastic force of the first spring 46. Similarly, a second spring 47 is fitted onto the second fixing rod 45. One end of the second spring 47 abuts against the second fixing plate of the second fixing rod 45, and the other end abuts against the second washer 49, which is also fitted onto the second fixing rod 45. The second washer 49 is fixedly connected to the second fixing rod 45, and the second fixing rod 45 abuts against the second fixing block 32 under the elastic force of the second spring 47. When the second fixing rod 45 reaches above the second fixing hole 321, it also enters the second fixing hole 321 under the combined action of its own weight and the elastic force of the first spring 46. The first spring 46 and the second spring 47 can significantly enhance the connection between the flip beam 4 and the first fixing block 22 or the second fixing block 32. Its structural design is simple and reliable, and provides a good user experience.

[0050] It should be noted that when the first door 2 or the second door 3 is opened, the first guide rod 21 or the second guide rod 31 first actuates the tilting beam 4 to rotate around the ball bearing 43. During the rotation, the first fixing rod 44 or the second fixing rod 45 enters the first fixing hole 221 or the second fixing hole 321 under the action of the first spring 46 or the second spring 47. At this time, the tilting beam 4 forms an effective connection with the first door 2 or the second door 3. Subsequently, the door body drives the tilting beam 4 to leave the box body 1. During the process of the tilting beam 4 leaving the box body 1, the ball bearing 43 moves along the arc-shaped groove of the mounting base 5, causing the tilting beam 4 to continue to tilt, and finally leave the box body in a vertical form. During this period, the movement trajectory of the ball bearing 43 is not necessarily circular, that is, the ball bearing acts as a universal wheel.

[0051] Furthermore, the structure of the flip beam 4 in this application can also be adjusted according to the circumstances. For details, please refer to [reference needed]. Figure 6 - Figure 8The flip beam 4 of this application includes a beam body 42 and a guide block 41 sleeved on the top of the beam body 42. The guide block 41 is connected to the beam body 42, and the first long groove 411, the first short groove 412, the second short groove 413, and the second long groove 414 are all provided on the guide block 41. Based on the above structure, the flip beam 4 of this application integrates key structures such as the first long groove 411, the first short groove 412, the second short groove 413, and the second long groove 414 on the guide block 41. When the above structure develops errors after long-term use, only the guide block 41 needs to be replaced to complete the update and maintenance of the flip beam 4. Its structural design is ingenious, easy to use, and easy to promote. Similarly, for cabinet doors of different sizes, users can also choose to replace the guide block 41 to complete the matching operation between the flip beam 4 and the cabinet door.

[0052] For further details, please refer to... Figure 6 , Figure 11 - Figure 13 The beam body 42 of this application includes a front cover plate 421 and a rear cover plate 422. The front cover plate 421 is connected to the rear cover plate 422. The first fixing rod 44 and the second fixing rod 45 are both located in the front cover plate 421. Since the bottom of the flip beam 4 is provided with a ball bearing 423, in order to avoid the ball bearing 423 from interfering with the first fixing block 22 or the second fixing block 32, this application chooses to open a support groove 4211 in the middle of the front cover plate 421. When the first box door 2 and the second box door 3 are closed, the first fixing block 22 and the second fixing block 32 enter the support groove 4211. At this time, the first fixing rod 44 and the second fixing rod 45 pass through the plate surface of the front cover plate 421 and abut against the first fixing block 22 and the second fixing block 32 respectively. The first fixing block 22 supports the first fixing rod 44 to ensure the fixed connection between the flip beam 4 and the first box door 2, and the second fixing block 32 can support the second fixing rod 45 to ensure the fixed connection between the flip beam 4 and the second box door 3.
