Description

Technical Field

[0001] The present application relates to the technical field of refrigeration equipment, and in particular to a refrigerator drawer linkage device and a refrigerator. Background Art

[0002] In order to meet user needs, refrigerators are generally equipped with a structure in which multiple drawers are linked to the door, so that when the door is opened, multiple drawers can be brought out at the same time. The existing structure that can achieve simultaneous linkage of multiple drawers and doors usually directly installs one of the drawers on the inner liner of the door through a door bracket, and then installs magnets on the other drawers and the corresponding positions of the inner liner of the door to achieve re-linkage of the other drawers and the door through magnetic attraction.

[0003] However, the magnet on the inner liner of the door protrudes from the overall setting of the door, which will affect the user's overall experience of using the refrigerator. The magnet on the drawer will absorb iron filings left when screwing on the door bracket, and the magnet is set facing the user, which further affects the user experience. Summary of the Invention

[0004] Based on this, it is necessary to provide a refrigerator drawer linkage device and a refrigerator that can improve the user experience while realizing the linkage between multiple drawers and doors.

[0005] To solve the above technical problems, this application provides the following technical solutions:

[0006] A refrigerator drawer linkage device is used to link a first drawer and a second drawer stacked along the height direction of the refrigerator, wherein the first drawer is mounted on the refrigerator door and the second drawer is slidably connected to the refrigerator body;

[0007] The refrigerator drawer linkage device includes a housing, a guide rod, a spring, and a linkage unit. The housing is used to be installed in the second drawer. The guide rod is installed in the housing and extends toward the first drawer along the height direction of the refrigerator. The spring is compressed and sleeved on the guide rod. One end of the spring is limited to the guide rod, and the other end is limited to the housing.

[0008] The linkage unit includes a linkage block and a locking block, wherein the linkage block is mounted on an end of the guide rod away from the housing, and the locking block is mounted on the first drawer, and a first inclined surface and a second inclined surface are provided on a side of the locking block facing the second drawer in the height direction of the refrigerator; along the direction in which the first drawer slides into the box body, the first inclined surface is behind the second inclined surface, and the first inclined surface gradually tilts upward relative to the horizontal plane in the height direction of the refrigerator, and the second inclined surface gradually tilts downward relative to the horizontal plane in the height direction of the refrigerator;

[0009] When the linkage block abuts against the first inclined surface, the linkage unit is in a locked state; when the linkage block passes through the first inclined surface and the second inclined surface and is separated from the locking block, the linkage unit is in an unlocked state.

[0010] As can be understood, the present application provides a housing, a guide rod, a spring, and a linkage unit, wherein the linkage block of the linkage unit is mounted at an end of the housing that is away from the guide rod and located in the second drawer, and the locking block is mounted in the first drawer. A first inclined surface on the locking block abuts against the linkage block to achieve stable linkage between the first and second drawers. The spring is in a compressed state so that the guide rod always drives the linkage block toward the linkage block, thereby increasing the reliability of the linkage between the two drawers. Furthermore, in the height direction of the refrigerator, the first inclined surface is tilted upward relative to the horizontal plane to ensure that the linkage unit is in a stable locked state, while the second inclined surface is tilted downward relative to the horizontal plane to achieve smooth separation. Furthermore, the guide rod and spring are located within the housing, so that the linkage structure is not directly visible to the user, thereby improving the user experience. That is, the present application utilizes the cooperation between the first and second inclined surfaces of the locking block and the linkage block, and the guide rod and spring are located within the housing, to achieve linkage between the two drawers and the door while improving the user experience.

[0011] In one embodiment, the angle between the first inclined plane and the horizontal plane is α, and the angle between the second inclined plane and the horizontal plane is β; α satisfies the relationship: 0≤α≤arctan , β satisfies the relationship: β≥arctan , β>α; wherein P is the vertical force between the linkage block and the locking block when the drawers are linked in the interlocking state, is the changing elastic force of the spring when it expands and contracts, Q is the initial elastic force of the spring, and R is the force required for the second drawer to return to the locked state.

[0012] It is understandable that the angle between the first inclined plane and the horizontal plane is set to be within the range of 0-arctan , so that the linkage unit can be stably locked; the angle β between the second inclined plane and the horizontal plane satisfies the relationship β≥arctan , so that the linkage block and the locking block can be separated smoothly and the two can be easily reset and locked.

[0013] In one embodiment, the angle α is negatively correlated with the elastic force of the spring.

[0014] It can be understood that the angle α is set to be negatively correlated with the elastic force of the spring, that is, the greater the elastic force, the smaller the angle α can be, so that by setting the compression force of the spring and the angle α, the force of the two on the locking block tending to the linkage block can meet the conditions for stable linkage between the locking block and the linkage block, so as to further ensure the reliability of the refrigerator drawer linkage device.

[0015] In one embodiment, a third inclined surface and a fourth inclined surface are provided on a side of the linkage block facing the locking block, and along the direction in which the first drawer slides into the box body, the third inclined surface is in front of the fourth inclined surface; and along the direction in which the first drawer slides out of the box body, the third inclined surface gradually tilts upward relative to the horizontal plane in the height direction of the refrigerator, and the fourth inclined surface gradually tilts downward relative to the horizontal plane in the height direction of the refrigerator;

[0016] Wherein, when the linkage unit is in a locked state, the third inclined surface is in contact with the first inclined surface; when the linkage block passes through the second inclined surface, the fourth inclined surface is in contact with the second inclined surface.

[0017] It can be understood that the setting of the third inclined surface can make the linkage block and the locking block face to face when the linkage unit is in a locked state. When the door is opened and the second drawer is brought out by the first drawer, the face-to-face abutment setting can increase the sliding friction between the two components of the linkage unit, thereby improving the reliability of the linkage. The cooperation between the fourth inclined surface and the second inclined surface gives the second drawer the advantage of guided sliding in the process of linkage with the first drawer, so as to ensure that the locking block can reach the locking position with the linkage block, further improving the user experience of the refrigerator drawer linkage device.

[0018] In one embodiment, the refrigerator drawer linkage device further includes a magnetic member and a matching member, one of the magnetic member and the matching member is fixed to the linkage block, and the other is used to be installed in the first drawer;

[0019] When the linkage block abuts against the first inclined surface, the magnetic component and the matching component are magnetically engaged with each other.

[0020] It can be understood that when the linkage block abuts against the first inclined surface and enters a locked state, the magnetic attraction between the magnetic part and the mating part can provide additional holding force, thereby ensuring that the linkage between the second drawer and the first drawer is more secure, that is, further improving the reliability of the linkage between the second drawer and the first drawer.

[0021] In one embodiment, the matching piece is configured as a rigid piece, the linkage block is configured as a flexible piece, and the matching piece is embedded in the linkage block.

[0022] It can be understood that the linkage block is configured as a flexible part so that it has anti-buffering ability, that is, it provides a buffering effect when the magnetic part and the mating part are attracted, reduces the rigid collision between the two, avoids damage to the structure and abnormal noise during collision, thereby extending the service life of the refrigerator drawer linkage device.

[0023] In one embodiment, the guide rod is threadedly connected to the mating piece.

[0024] It is understandable that threaded connection between the guide rod and the mating piece makes the two easy to be inserted and removed for replacement or maintenance, thereby reducing the maintenance cost of the device.

[0025] This application also provides the following technical solutions:

[0026] A refrigerator, comprising a refrigerator body, a door, a first drawer, a second drawer, and the refrigerator drawer linkage device as described in any one of the above embodiments;

[0027] The first drawer is mounted on the box body and is slidably connected to the box body, and the second drawer is stacked above the first drawer in the height direction of the refrigerator and is slidably connected to the box body;

[0028] The refrigerator drawer linkage device can link the first drawer and the second drawer when the cabinet door is opened, so that the first drawer and the second drawer can slide out of the cabinet synchronously.

[0029] In one embodiment, a mounting seat is provided on the side of the second drawer, a mounting groove is provided on the mounting seat, and the shell is installed in the mounting groove and is detachably connected to the mounting seat.

[0030] In one embodiment, the refrigerator drawer linkage device is provided in plurality, and the plurality of refrigerator drawer linkage devices are arranged at intervals along the width direction of the box body.

[0031] It can be understood that multiple refrigerator drawer linkage devices are set up and arranged at intervals along the width direction of the box body, so that the second drawer can be subjected to balanced force during movement through multiple linkage devices, avoiding deflection or jamming caused by single-point force, and further increasing the reliability of the linkage process between the second drawer and the first drawer.

[0032] Compared to the prior art, the refrigerator drawer linkage device and refrigerator are provided with a housing, a guide rod, a spring, and a linkage unit. The linkage block of the linkage unit is mounted on the end of the housing that is away from the guide rod and is located at the second drawer. The locking block is mounted on the first drawer. The first inclined surface of the locking block abuts against the linkage block to achieve stable linkage between the first and second drawers. The spring is in a compressed state so that the guide rod always drives the linkage block toward the linkage block, thereby improving the reliability of the linkage between the two drawers. At the same time, in the height direction of the refrigerator, the first inclined surface is tilted upward relative to the horizontal plane to ensure that the linkage unit is in a stable locked state, and the second inclined surface is tilted downward relative to the horizontal plane to achieve smooth separation. The guide rod and spring are located inside the housing, so that the linkage structure is not directly visible to the user, thereby improving the user experience. That is, the present application utilizes the cooperation between the first and second inclined surfaces of the locking block and the linkage block, and the guide rod and spring are located inside the housing to achieve linkage between the two drawers and the door while improving the user experience.

[0047] See also Figure 1 The present application provides a refrigerator, including a cabinet, a cabinet door 201, a first drawer 202, a second drawer 203 and a refrigerator drawer linkage device 100; the first drawer 202 is installed in the cabinet and is slidably connected to the cabinet, and the second drawer 203 is stacked above the first drawer 202 in the height direction z of the refrigerator and is slidably connected to the cabinet; wherein the refrigerator drawer linkage device 100 can link the first drawer 202 and the second drawer 203 when the cabinet door 201 is opened, so that the first drawer 202 and the second drawer 203 can slide out of the cabinet synchronously.

[0048] Specifically, if Figure 2 and Figure 3 As shown, the refrigerator drawer linkage device 100 includes a housing 10, a guide rod 20, a spring 30 and a linkage unit 40. The housing 10 is used to be installed in the second drawer 203. The guide rod 20 is installed on the housing 10 and extends toward the first drawer 202 along the height direction z of the refrigerator. The spring 30 is sleeved on the guide rod 20 in a compressed manner, and one end of the spring 30 is limited to the guide rod 20, and the other end is limited to the housing 10; the linkage unit 40 includes a linkage block 41 and a locking block 42. The linkage block 41 is installed at one end of the guide rod 20 away from the housing 10, and the locking block 42 is installed in the first drawer 202, and the locking block 42 is in the height direction of the refrigerator. z and a first inclined surface 421 and a second inclined surface 422 are provided on the side facing the second drawer 203; along the direction x in which the first drawer 202 slides into the box body, the first inclined surface 421 is behind the second inclined surface 422, and the first inclined surface 421 gradually tilts upward relative to the horizontal plane in the height direction z of the refrigerator, and the second inclined surface 422 gradually tilts downward relative to the horizontal plane in the height direction z of the refrigerator; wherein, when the linkage block 41 abuts against the first inclined surface 421, the linkage unit 40 is in a locked state; when the linkage block 41 passes through the first inclined surface 421 and the second inclined surface 422 and is separated from the locking block 42, the linkage unit 40 is in an unlocked state.

[0049] The second drawer 203 is locked and the second drawer 203 is locked. That is, this application utilizes the cooperation between the first inclined surface 421 and the second inclined surface 422 of the locking block 42 and the linkage block 41, and arranges the guide rod 20 and the spring 30 in the shell 10, so as to realize the linkage between the two drawers and the box door 201 while improving the user experience.

[0050] like Figures 2 to 5 As shown, a third inclined surface 411 and a fourth inclined surface 412 are provided on one side of the linkage block 41 facing the locking block 42. Along the direction x in which the first drawer 202 slides into the box body, the third inclined surface 411 is in front of the fourth inclined surface 412; and, along the direction x in which the first drawer 202 slides out of the box body, the third inclined surface 411 gradually tilts upward relative to the horizontal plane in the height direction z of the refrigerator, and the fourth inclined surface 412 gradually tilts downward relative to the horizontal plane in the height direction z of the refrigerator; wherein, when the linkage unit 40 is in a locked state, the third inclined surface 411 is in contact with the first inclined surface 421; when the linkage block 41 passes the second inclined surface 422, the fourth inclined surface 412 is in contact with the second inclined surface 422. In this way, the setting of the third inclined surface 411 can enable the linkage unit 40 to be in a locked state, and the third inclined surface 411 is in contact with the first inclined surface 421, so that when the door 201 is opened and the second drawer 203 is brought out by the first drawer 202, the surfaces are in contact with each other, so as to increase the sliding friction between the two components of the linkage unit 40, thereby improving the reliability of the linkage; and the cooperation of the fourth inclined surface 412 and the second inclined surface 422 gives the second drawer 203 the advantage of guided sliding in the process of linkage with the first drawer 202, so as to ensure that the locking block 42 can reach the locking position with the linkage block 41, further improving the user experience of the refrigerator drawer linkage device 100.

[0051] In one embodiment, the angle between the first inclined surface 421 and the horizontal plane is α, and the angle between the second inclined surface 422 and the horizontal plane is β; α satisfies the relationship: 0≤α≤arctan , β satisfies the relationship: β≥arctan , β>α; where P is the vertical force between the linkage block 41 and the locking block 42 when the drawers are in the interlocked state, is the change in elastic force of the spring 30 when it is extended and retracted, Q is the initial elastic force of the spring 30, and R is the force required for the second drawer 203 to be reset to the locked state. It can be understood that the angle between the first inclined surface 421 and the horizontal plane is set in the range of 0-arctan , so that the linkage unit 40 is stably in a locked state; the angle β between the second inclined surface 422 and the horizontal plane satisfies the relationship β≥arctan , so that the linkage block 41 and the locking block 42 can be smoothly separated and the two can be easily reset and locked.

[0052] Preferably, the angle α is negatively correlated with the elastic force of the spring 30. That is, the greater the elastic force of the spring 30, the smaller the angle α can be. By adjusting the compression force of the spring 30 and the angle α, the forces exerted by the spring 30 on the locking block 42 toward the linkage block 41 satisfy the condition for stable linkage between the locking block 42 and the linkage block 41, thereby further ensuring the reliability of the refrigerator drawer linkage device 100.

[0053] In one embodiment, the refrigerator drawer linkage device 100 further includes a magnetic member 50 and a mating member (not shown). One of the magnetic member 50 and the mating member is fixed to the linkage block 41, and the other is mounted on the first drawer 202. When the linkage block 41 abuts the first inclined surface 421, the magnetic member 50 and the mating member engage magnetically. Thus, when the linkage block 41 abuts the first inclined surface 421 and enters a locked state, the magnetic attraction between the magnetic member 50 and the mating member provides additional holding force, thereby ensuring a more secure linkage between the second drawer 203 and the first drawer 202, further enhancing the reliability of the linkage between the second drawer 203 and the first drawer 202.

[0054] Furthermore, the mating member is configured as a rigid member, and the linkage block 41 is configured as a flexible member, with the mating member embedded in the linkage block 41. It is understood that the flexible member has a buffering capability, and configuring the linkage block 41 as a flexible member can provide a buffering effect when the magnetic member 50 and the mating member are attracted, reducing the rigid collision between the two, avoiding damage to the structure and abnormal noise during the collision, thereby extending the service life of the refrigerator drawer linkage device 100.

[0055] Here, the flexible member may be made of rubber or the like.

[0056] Preferably, the mating member is threadedly connected to the guide rod 20. This connection makes the mating member easy to remove, replace, or repair, thereby reducing the maintenance cost of the device. Of course, the mating member and the guide rod 20 can be connected in other ways, which are not limited here. The specific connection method can be determined according to actual circumstances.

[0057] Please continue to refer to Figure 1 、 Figure 2 and Figure 5 A mounting base 204 is provided on the side of the second drawer 203. The mounting base 204 has a mounting groove 2041. The housing 10 is mounted in the mounting groove 2041 and is detachably connected to the mounting base 204. It is understood that the detachable connection allows the housing 10 to be plugged in and out of the mounting base 204, exposing the guide rod 20 and the spring 30 for easy inspection, maintenance, or replacement.

[0058] Here, the housing 10 and the mounting base 204 can be detachably connected by a snap-fit structure, etc. Of course, the connection method is not limited to this, and the specific connection structure can be determined according to actual conditions.

[0059] In one embodiment, multiple refrigerator drawer linkage devices 100 are provided, and the multiple refrigerator drawer linkage devices 100 are spaced apart along the width of the refrigerator body. This allows the multiple linkage devices to balance the forces acting on the second drawer 203 during movement, preventing deflection or jamming caused by a single point of force, and further increasing the reliability of the linkage between the second drawer 203 and the first drawer 202.

[0060] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned 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.

[0061] The above-described embodiments merely represent several implementation methods of the present application. 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 variations and improvements can be made by a person of ordinary skill in the art without departing from the spirit of the present application, and these variations and improvements fall within the scope of protection of the present application. Therefore, the scope of patent protection for the present application shall be determined by the appended claims.
