Description

Technical Field

[0001] This utility model relates to the field of refrigeration equipment technology, and in particular to a refrigerator linkage device and a refrigerator. Background Technology

[0002] Refrigerator interlocking devices are mainly used to link the refrigerator door and drawers. Existing refrigerator door and drawer interlocking devices usually use a sliding rail structure or magnetic attraction, and usually require an additional unlocking component so that the drawer can be unlocked and removed separately after being pulled out along with the refrigerator door.

[0003] However, this dual-set structure is quite complex and takes up a lot of storage space. In actual use, users need to use the unlocking component separately to unlock the linked drawer from the refrigerator door and then take the drawer out separately. The operation is cumbersome and time-consuming, which affects the user experience. Utility Model Content

[0004] Therefore, it is necessary to provide a refrigerator linkage device and refrigerator that can simultaneously achieve the linkage and assisted unlocking of drawers and refrigerator doors through a simple structure, and is easy to operate without taking up too much storage space.

[0005] To solve the above-mentioned technical problems, this application provides the following technical solution:

[0006] A refrigerator linkage device is disclosed for linking a refrigerator door and a drawer. The linkage device includes a fixed base, a locking block, and a pushing assembly. The fixed base is mounted on the refrigerator door and has a rotating groove and a channel. The channel has a first opening and a second opening. The first opening faces the height direction of the refrigerator, and the second opening faces the depth direction of the refrigerator. The locking block has a first end and a second end in the depth direction of the refrigerator. The first end is rotatably connected to the side wall of the rotating groove in the width direction of the refrigerator. The second end extends out of the rotating groove and has a latching part. In response to the rotation of the locking block, the latching part engages or disengages from the drawer. The pushing assembly is mounted on the channel and has a third end and a fourth end. The third end corresponds to the first opening and can extend into or out of the first opening to engage with the first end. The fourth end corresponds to the second opening and can extend into or out of the second opening to engage with the drawer.

[0007] In response to the latching part releasing its engagement with the drawer and being squeezed by the first end, the third end retracts into the channel through the first opening, and the fourth end extends out of the second opening and pushes the drawer in the depth direction of the refrigerator; or in response to the latching block engaging the drawer and being squeezed by the drawer, the fourth end retracts into the channel through the second opening, and the third end extends out of the first opening.

[0008] Understandably, this application, by setting a fixing base, a snap-fit ​​block, and a push-pull assembly, installs a fixing base with a rotating groove and a channel on the refrigerator door. The rotation of the snap-fit ​​block installed in the rotating groove allows the second end of the snap-fit ​​block to act on the drawer, achieving linkage between the drawer and the refrigerator door. Simultaneously, the first end of the snap-fit ​​block acts on the push-pull assembly, allowing the push-pull assembly to extend out of the second opening of the channel and push the drawer in the depth direction of the refrigerator, thus achieving assisted unlocking of the drawer and refrigerator door. In this way, the linkage structure between the drawer and refrigerator door and the assisted unlocking structure are integrated, forming a simple structure with both linkage and assisted unlocking functions. This not only avoids occupying too much storage space but also simplifies operation, as both linkage and assisted unlocking functions can be achieved simply by rotating the snap-fit ​​block.

[0009] In one embodiment, the passage includes a first passage and a second passage that are interconnected, the first passage extending along the height direction of the refrigerator, and the first opening being disposed in the first passage; the second passage extends toward the drawer.

[0010] The push-up assembly includes a transmission rod and an ejector rod. The transmission rod is installed in the first channel, with one end of the transmission rod located inside the first channel and the other end able to extend or enter the first channel through the first opening and to cooperate with the first end. One end of the ejector rod is located inside the second channel and cooperates with the transmission rod, while the other end can extend or enter the first channel through the first opening and to push the drawer.

[0011] Understandably, by using the dual-channel and separate rod configuration of the first channel, second channel, transmission rod, and ejector rod, the refrigerator's linkage device achieves the goal of rotating and squeezing the transmission rod with the locking block within a compact space. This force is then transmitted and converted into a pushing force towards the drawer, enabling assisted drawer unlocking. Thus, simply rotating the locking block allows for easy drawer unlocking, simplifying operation and minimizing space requirements. Furthermore, the first and second channels ensure the precision of the transmission rod and ejector rod's movement trajectories, further enhancing the user experience.

[0012] In one embodiment, the second channel is inclined relative to the depth direction of the refrigerator and forms an obtuse angle with the axis of the first channel.

[0013] Understandably, the second channel is set at an obtuse angle to the first channel, which allows the ejector rod to move naturally outward and eject the drawer when the drawer is unlocked, thus improving the smoothness of the unlocking mechanism's movement.

[0014] In one embodiment, the inner wall of the second channel is provided with a blocking part in the depth direction of the refrigerator, and the end of the ejector rod near the transmission rod is provided with a mating part, and the blocking part and the mating part can be engaged in a preset position.

[0015] Understandably, the blocking part works in conjunction with the mating part to block the ejector rod when it extends out of the second channel, preventing it from moving excessively towards the drawer along the depth of the refrigerator and falling off, thus ensuring the practicality and stability of the structure.

[0016] In one embodiment, the latching portion protrudes from the surface of the latching block and forms a latching groove with the latching block, the latching groove being used to latch the drawer;

[0017] The wall surface of the latching part located within the latching groove is configured as a first inclined surface, which is used to abut against the drawer.

[0018] In one embodiment, the first inclined surface is provided with an anti-slip texture.

[0019] Understandably, setting anti-slip texture on the first slope can increase the contact friction between the latch and the drawer, ensuring that the latch slides away from the drawer as it is pulled out along with the refrigerator door, thus preventing the drawer and refrigerator door from malfunctioning.

[0020] In one embodiment, the snap-fit ​​block is provided with a clearance groove at the first end position, the clearance groove being used to avoid the transmission rod.

[0021] Understandably, when the drawer is linked with the refrigerator door, the drive rod extends into the first channel and into the rotating groove. The clearance groove at this time can prevent the drive rod from contacting the locking block. This prevents the locking block from being directly squeezed by the force of the drawer rotating in the direction of the refrigerator depth when the drawer is pulled out with the refrigerator door, thus avoiding abnormal unlocking of the drawer.

[0022] In one embodiment, a spring is provided in the rotating groove, the spring is arranged along the height direction of the refrigerator, and one end of the spring is limited to the bottom wall of the rotating groove in the height direction of the refrigerator, and the other end is limited to the first end.

[0023] Understandably, the springs designed to engage the drawer and refrigerator door during linkage use their tension to keep the locking block engaged with the drawer, preventing the locking block from rotating freely and affecting the linkage effect. In other words, the springs further enhance the reliability and stability of the refrigerator linkage device.

[0024] In one embodiment, the springs are provided in multiples, and the multiple springs are spaced apart along the width direction of the refrigerator.

[0025] Understandably, the spacing of multiple springs along the width of the refrigerator helps to distribute the tension on the locking block, preventing it from tilting or wobbling due to single-point force, which would affect the linkage status and the user experience.

[0026] This application also provides the following technical solutions:

[0027] A refrigerator includes a refrigerator door, a drawer, and a refrigerator linkage device as described in any of the above embodiments, wherein the drawer and the refrigerator door move synchronously through the refrigerator linkage device.

[0028] Compared with existing technologies, the refrigerator linkage device and refrigerator described above, by setting a fixed base, a snap-fit ​​block, and a push-pull assembly, install the fixed base with a rotating groove and a channel on the refrigerator door. By rotating the snap-fit ​​block installed in the rotating groove, the second end of the snap-fit ​​block can act on the drawer, realizing the linkage between the drawer and the refrigerator door. The first end of the snap-fit ​​block can act on the push-pull assembly, allowing the push-pull assembly to extend out of the second opening of the channel and push the drawer in the depth direction of the refrigerator, realizing the assisted unlocking of the drawer and the refrigerator door. In this way, the linkage structure between the drawer and the refrigerator door and the assisted unlocking structure are integrated to form a simple structure with linkage and assisted unlocking functions. This not only avoids occupying too much storage space, but also only requires rotating the snap-fit ​​block to realize the two functions of linkage and assisted unlocking, making the operation relatively simple.

[0042] Please see Figures 1 to 5 This application provides a refrigerator linkage device 100, which mainly achieves linkage between drawer 201 and refrigerator door 202 and assists in unlocking through a simple structural cooperation.

[0043] Specifically, the refrigerator linkage device 100 includes a fixed base 10, a snap-fit ​​block 20, and a push assembly 30. The fixed base 10 is used to install on the refrigerator door 202, and the fixed base 10 has a rotating groove 11 and a channel 12. The channel 12 has a first opening 121 and a second opening 122. The first opening 121 is oriented towards the height direction z of the refrigerator, and the second opening 122 is oriented towards the depth direction x of the refrigerator. The snap-fit ​​block 20 has a first end 21 and a second end 22 in the depth direction x of the refrigerator. The first end 21 is rotatably connected to the side wall of the rotating groove 11 in the width direction y of the refrigerator. The second end 22 extends out of the rotating groove 11 and has a latching part 23. In response to the rotation of the snap-fit ​​block 20, the latching part 23 latches onto or releases from the drawer 201. The push assembly 30 is installed... The refrigerator has a channel 12 and a third end 31 and a fourth end 32. The third end 31 corresponds to the first opening 121 and can extend into or out of the first opening 121 and is used to engage with the first end 21. The fourth end 32 corresponds to the second opening 122 and can extend into or out of the second opening 122 and is used to engage with the drawer 201. In response to the latching part 23 releasing the latch from the drawer 201 and being pressed by the first end 21, the third end 31 retracts into the channel 12 through the first opening 121, and the fourth end 32 extends out of the second opening 122 and pushes the drawer 201 in the depth direction x of the refrigerator. Or, in response to the latching block 20 engaging the drawer 201 and being pressed by the drawer 201, the fourth end 32 retracts into the channel 12 through the second opening 122, and the third end 31 extends out of the first opening 121.

[0044] It should be explained that this application, by setting a fixing base 10, a snap-fit ​​block 20, and a push-up assembly 30, installs the fixing base 10, which has a rotating groove 11 and a channel 12, on the refrigerator door 202. By rotating the snap-fit ​​block 20 installed in the rotating groove 11, the second end 22 of the snap-fit ​​block 20 can act on the drawer 201, realizing the linkage between the drawer 201 and the refrigerator door 202. The first end 21 of the snap-fit ​​block 20 can act on the push-up assembly 30, allowing the push-up assembly 30 to extend out of the second opening 122 of the channel 12 and push the drawer 201 in the depth direction x of the refrigerator, realizing the assisted unlocking of the drawer 201 and the refrigerator door 202. In this way, the linkage structure and the assisted unlocking structure of the drawer 201 and the refrigerator door 202 are integrated to form a simple structure with linkage and assisted unlocking functions. This not only avoids occupying too much storage space, but also only requires rotating the snap-fit ​​block 20 to realize the two functions of linkage and assisted unlocking, making the operation relatively simple and improving the user experience.

[0045] like Figure 2 and Figure 3As shown, the channel 12 includes a first channel 123 and a second channel 124 that are interconnected. The first channel 123 extends along the height direction z of the refrigerator, and a first opening 121 is provided in the first channel 123. The second channel 124 extends toward the drawer 201. The push assembly 30 includes a transmission rod 33 and a push rod 34. The transmission rod 33 is installed in the first channel 123, and one end of the transmission rod 33 is located inside the first channel 123, while the other end can extend or extend into the first channel 123 through the first opening 121 and is used to cooperate with the first end 21. One end of the push rod 34 is located inside the second channel 124 and cooperates with the transmission rod 33, while the other end can extend or extend into the first channel 123 through the first opening 121 and is used to push the drawer 201. Thus, the transmission rod 33 in the push assembly 30 can extend into the rotating groove 11 through the first opening 121 at the first channel 123, so as to be able to withstand the squeezing force when the locking block 20 rotates, and to transmit the squeezing force to the push rod 34, so that the push rod 34 extends out of the second opening 122 through the second channel 124 to push the drawer 201, thereby achieving the assisted unlocking of the drawer 201 more easily.

[0046] Here, through the dual-channel and split rod setup, the refrigerator linkage device 100, within a compact space, transmits and converts the force of the locking block 20 rotating and pressing the transmission rod 33 into a pushing force towards the drawer 201, thus enabling the drawer to be unlocked with assistance. In this way, simply rotating the locking block is enough to easily unlock the drawer, making the operation simpler and the structure less space-consuming. Furthermore, the first and second channels can respectively ensure the accuracy of the movement trajectory of the transmission rod and the push rod, which further enhances the user experience.

[0047] In one embodiment, the position of the ejector rod 34 near the transmission rod 33 is set as a second inclined surface (not shown). After the transmission rod 33 is subjected to the squeezing force of the locking block 20, it can act on the second inclined surface, so that the squeezing force is converted into the pushing force of the ejector rod 34 on the drawer 201, thereby realizing the assisted unlocking function of the refrigerator linkage device 100 on the drawer 201.

[0048] In another embodiment, the second channel 124 is inclined relative to the depth direction x of the refrigerator and forms an obtuse angle with the axis of the first channel 123. Thus, when the drawer 201 needs to be unlocked, the push rod 34 located in the second channel 124 can naturally extend outward from the second opening 122, providing a pushing assist to the drawer 201. That is, the obtuse angle between the second channel 124 and the first channel 123 improves the smoothness of the pushing component 30's movement when the refrigerator linkage device 100 performs the assisted unlocking function.

[0049] Furthermore, a blocking part 1241 is provided on the inner wall of the second channel 124 in the depth direction x of the refrigerator, and a mating part 341 is provided at the end of the ejector rod 34 near the transmission rod 33. The blocking part 1241 and the mating part 341 can engage in a preset position. It can be understood that this preset position is the position where the ejector rod 34 can move along the maximum path of the drawer 201 relative to the transmission rod 33 in the depth direction x of the refrigerator. By engaging the blocking part 1241 and the mating part 341, when the ejector rod 34 extends out of the second channel 124, it can be blocked, preventing it from moving excessively and dislodging from the second channel 124, thus affecting the user's use. That is, the setting of the blocking part 1241 and the mating part 341 ensures the stable positioning of the push assembly 30 and further improves the user's experience of the refrigerator linkage device 100.

[0050] like Figures 2 to 5 As shown, the latching part 23 protrudes from the surface of the latching block 20 and forms a latching groove 231 with the latching block 20. The latching groove 231 is used to latch the drawer 201. The wall surface of the latching part 23 located in the latching groove 231 is set as a first inclined surface 232, which is used to abut against the drawer 201.

[0051] In one embodiment, the first inclined surface 232 is provided with an anti-slip texture 2321. In this way, the anti-slip texture 2321 can increase the contact friction between the latching part 23 and the drawer 201, ensuring that the latching part 23 slides and separates from the drawer 201 when the drawer 201 is pulled out in conjunction with the refrigerator door 202, thus avoiding the failure of the linkage between the drawer 201 and the refrigerator door 202.

[0052] like Figure 3 As shown, the wall surface of the latch 23 facing the drawer 201 is configured as a third inclined surface 233. The third inclined surface 233 is used to guide the drawer 201 smoothly into the latch groove 231 when the refrigerator door 202 is closed.

[0053] Here, the third slope 233 can be set as an arc slope. This increases the smoothness of the drawer 201 moving into the latch 231 and avoids sudden contact between the drawer 201 and the latch, which could cause impact and damage.

[0054] Preferably, the latching block 20 is provided with a relief groove 24 at the first end 21, which is used to avoid the transmission rod 33. It can be understood that when the drawer 201 is linked with the refrigerator door 202, the transmission rod 33 will extend out of the first channel 123 into the rotating groove 11. At this time, the relief groove 24 can prevent the transmission rod 33 from contacting the latching block 20, and prevent the latching block 20 from being directly squeezed by the force of the drawer 201 in the refrigerator depth direction x when the drawer 201 is pulled out in conjunction with the refrigerator door 202, causing the push rod 34 to extend out of the second channel 124 to push the drawer 201 and make it unlock abnormally.

[0055] Please continue to refer to this. Figures 1 to 3 A spring 40 is installed inside the rotating groove 11. The spring 40 is positioned along the height direction z of the refrigerator, with one end of the spring 40 limited to the bottom wall of the rotating groove 11 in the height direction z of the refrigerator, and the other end limited to the first end 21. In this way, the tension of the spring 40 can be used to keep the locking block 20 in a locked state with the drawer 201. That is, by setting the spring 40, the locking block 20 can be kept in a stable state and will not rotate arbitrarily, thereby improving the overall reliability and stability of the refrigerator linkage device 100 during operation.

[0056] In one embodiment, multiple springs 40 are provided, and the multiple springs 40 are spaced apart along the width direction y of the refrigerator. In this way, the tension on the latching block 20 can be distributed, avoiding tilting or shaking of the latching block 20 due to single-point force, which would affect the linkage state and the user's experience.

[0057] Here, the number of springs 40 can be two, three, or five. Of course, this is not a limitation; the specific number of springs 40 can be determined according to the actual situation. In this embodiment, two springs 40 are used.

[0058] Furthermore, mounting bases 41 are provided on the fixed base 10 and the snap-fit ​​block 20. The spring 40 is connected and fixed to the fixed base 10 and the snap-fit ​​block 20 respectively at both ends of the refrigerator height direction z through the mounting bases 41. In this way, the mounting bases 41 make the installation of the spring 40 more secure and reliable, thereby further improving the user's experience of using the refrigerator linkage device 100.

[0059] This application also provides a refrigerator, including a refrigerator door 202, a drawer 201, and a refrigerator linkage device 100 in any of the above embodiments, wherein the drawer 201 and the refrigerator door 202 move synchronously through the refrigerator linkage device 100.

[0060] When the refrigerator linkage device 100 links the drawer 201 and the refrigerator door 202, the latching part 23 of the latching block 20 engages with the drawer 201 (see...). Figure 4 When drawer 201 unlocks and disengages from refrigerator door 202, locking block 20 rotates, and latching part 23 separates from drawer 201. At the same time, the first end of locking block 20 presses transmission rod 33, which transmits pressure to ejector rod 34, causing ejector rod 34 to extend out of second opening 122, thereby pushing drawer 201 and achieving assisted unlocking of drawer 201 (see...). Figure 5 ).

[0061] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0062] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
