Abstract
Description
Technical Field
[0001] This application relates to the field of refrigerator technology, and in particular to a refrigerator drawer linkage device and a refrigerator. Background Technology
[0002] To meet user needs, some refrigerators feature a structure where multiple drawers are linked to the door, allowing multiple drawers to be pulled out simultaneously when the door is opened. This structure typically involves mounting one drawer directly onto the inner liner of the door via a door bracket, and installing magnets on the other drawers and corresponding positions on the inner liner of the door to achieve magnetic attraction and linkage between the other drawers and the door.
[0003] Magnets attract iron filings produced when screwing in the door frame, causing rust and damaging the drawer's appearance. Furthermore, in order for the magnets inside the drawer to attract each other, a raised structure needs to be made on the door liner, affecting the overall aesthetic experience. Utility Model Content
[0004] Therefore, it is necessary to provide a refrigerator drawer linkage device and refrigerator that can achieve linkage between multiple drawers and cabinet doors while avoiding the rusting caused by the attraction of iron filings by magnets and the impact on the overall appearance of the refrigerator.
[0005] A refrigerator drawer linkage device is disclosed for linking a first drawer and a second drawer stacked along the height direction z of the refrigerator. The first and second drawers are slidably connected to the refrigerator body. The first drawer is located below the second drawer along the height direction z and is installed to the door. The refrigerator drawer linkage device includes a mounting base, a latch, and a locking engagement component. The mounting base is installed to the second drawer. The latch is movably connected to the mounting base along the height direction z of the refrigerator. The locking engagement component is installed to the first drawer and has a slot facing the latch. The latch is engaged with the slot under its own weight and can move upward along the height direction z of the refrigerator to disengage from the slot in response to external force.
[0006] In one embodiment, along the height direction z of the refrigerator, the lower end face of the latch is configured as a guide slope. Along the front-rear direction x of the refrigerator, the guide slope extends from the front end face of the latch to the rear end face of the latch and gradually downwards along the height direction z of the refrigerator. Along the front-rear direction x of the refrigerator, the rear end face of the locking engagement member is suspended. As the first drawer moves backward relative to the first drawer along the front-rear direction x of the refrigerator, the rear end face of the locking engagement member can cooperate with the guide slope to push the latch upwards along the height direction z of the refrigerator and insert the latch into the insertion slot.
[0007] In one embodiment, the rear end face of the locking member is configured as an arc surface along the front-rear direction x of the refrigerator.
[0008] In one embodiment, the guide ramp and the front and rear faces of the latch along the front-rear direction x of the refrigerator are respectively provided with arc-shaped transition sections.
[0009] In one embodiment, the insertion slot includes a first surface and a second surface connected to each other. The first surface is arranged forward along the front-rear direction x of the refrigerator and is used to stop the pin at the rear end surface along the front-rear direction x of the refrigerator. The second surface is arranged upward along the height direction x of the refrigerator. The shape of the second surface is adapted to the shape of the guide slope and is used to fit against the guide slope.
[0010] In one embodiment, the mounting base has an installation channel, and the pin includes a rod and a stop head. The rod is movably inserted through the installation channel along the height direction of the refrigerator, and one end of the rod extends out of the installation channel and is used for insertion into the slot. The other end is connected to the stop head and can stop and cooperate with the upper surface of the mounting base along the height direction z of the refrigerator through the stop head.
[0011] In one embodiment, the mounting base includes a main body and flanges connected to both sides of the main body. The main body has a groove and is fastened to a second drawer. The flanges are detachably connected to the second drawer, and the inner wall of the groove and the surface of the second drawer form an installation channel.
[0012] In one embodiment, the mounting base is configured as a bent element, and the cross-section of the bent element is shaped like a "U".
[0013] In one embodiment, the locking engagement is mounted on the open edge of the first drawer and corresponding to the mounting base, and the locking engagement is configured to extend along the front-rear direction x of the refrigerator.
[0014] A refrigerator includes a cabinet, a door, a first drawer, a second drawer, and a refrigerator drawer linkage device as described in any of the above embodiments; the first drawer and the second drawer are slidably connected to the cabinet, the first drawer is located below the second drawer along the height direction z of the refrigerator and is installed to the door, and the refrigerator drawer linkage device can link the first drawer and the second drawer when the door is opened, so that the second drawer and the first drawer slide out of the cabinet synchronously.
[0015] Compared with existing technologies, the refrigerator drawer linkage device and refrigerator provided in this application, when the latch remains engaged with the slot under its own weight, the first and second drawers are locked. Rotating the door at this time allows the first and second drawers to slide synchronously, thus achieving linkage between the first and second drawers and the door. When an external force is applied, such as pushing the latch upwards along the refrigerator's height (z-axis), causing it to disengage from the slot, the first and second drawers are unlocked and can slide independently. Furthermore, by using a mounting base, latch, and locking mechanism, the magnet is eliminated, thus preventing the problem of rust caused by iron filings from screwing in the door bracket and avoiding the issue of a protruding structure on the door panel affecting the overall appearance of the refrigerator.

The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.
[0027] Please see Figures 1 to 3This application provides a refrigerator drawer linkage device 100 for linking a first drawer 200 and a second drawer 300 stacked along the refrigerator's height direction z. The first drawer 200 and the second drawer 300 are slidably connected to the refrigerator body. The first drawer 200 is located below the second drawer 300 along the refrigerator's height direction z and is installed to the door. The refrigerator drawer linkage device 100 includes a mounting base 10, a pin 20, and a locking engagement member 30. The mounting base 10 is installed to the second drawer 300. The pin 20 is movably connected to the mounting base 10 along the refrigerator's height direction z. The locking engagement member 30 is installed to the first drawer 200, and a groove 31 is formed on the upper surface of the locking engagement member 30 along the refrigerator's height direction z, facing the pin 20. The pin 20 remains engaged with the groove 31 under its own weight and can move upwards along the refrigerator's height direction z to disengage from the groove 31 in response to external forces.
[0028] Understandably, when the latch 20 remains engaged with the slot 31 under its own weight, the first drawer 200 and the second drawer 300 are locked. Rotating the door at this time allows the first drawer 200 and the second drawer 300 to slide synchronously, thus achieving linkage between the first drawer 200, the second drawer 300, and the door. When an external force is applied, such as pushing the latch 20 upwards along the height z of the refrigerator, causing the latch 20 to disengage from the slot 31, the first drawer 200 and the second drawer 300 are unlocked and can slide independently. Compared to related structures where one drawer is directly mounted on the inner liner of the cabinet door via a door bracket, and magnets are installed on other drawers and corresponding positions on the inner liner of the cabinet door to achieve linkage between the other drawers and the cabinet door through magnetic attraction, this application eliminates the magnets by setting up the mounting base 10, the latch 20, and the locking fitting 30. This avoids the problem of rust caused by iron filings generated when screwing the door bracket with magnets, and also avoids the problem of the overall appearance of the refrigerator being affected by the protruding structure at the magnet installation position on the door liner.
[0029] like Figure 4 As shown, along the height direction z of the refrigerator, the lower end face of the latch 20 is configured as a guide slope 21. Along the front-rear direction x of the refrigerator, the guide slope 21 extends from the front end face of the latch 20 to the rear end face of the latch 20 and gradually downwards along the height direction z of the refrigerator. Along the front-rear direction x of the refrigerator, the rear end face of the locking engagement 30 is suspended. As the first drawer 200 moves backward relative to the first drawer 200 along the front-rear direction x of the refrigerator, the rear end face of the locking engagement 30 can cooperate with the guide slope 21 to push the latch 20 upwards along the height direction z of the refrigerator and insert the latch 20 into the insertion slot 31.
[0030] It should be noted that the front of the refrigerator refers to the direction facing the opening of the inner liner, while the rear of the refrigerator refers to the direction facing the opposite direction. Understandably, by setting the guide ramp 21, which engages with the rear end face of the locking engagement 30, a guiding function is provided. As the first drawer 200 moves rearward relative to the refrigerator along the front-rear direction x, the rear end face of the locking engagement 30 engages with the guide ramp 21 to push the latch 20 upward along the refrigerator's height direction z to the upper end face of the locking engagement 30, and then slides along the upper end face until it inserts into the insertion slot 31 under its own weight. Thus, the relative movement of the first drawer 200 and the second drawer 300 along the front-rear direction x achieves automatic locking of the first drawer 200 and the second drawer 300, making operation convenient.
[0031] Optionally, in one embodiment, the rear end face of the locking engagement member 30 is configured as an arc surface along the front-rear direction x of the refrigerator. Since the rear end face of the locking engagement member 30 is used to engage with the guide ramp 21, configuring the rear end face of the locking engagement member 30 as an arc surface helps to reduce the friction between the rear end face of the locking engagement member 30 and the guide ramp 21, and facilitates pushing the pin 20 upward along the height direction z of the refrigerator to the upper end face of the locking engagement member 30.
[0032] Optionally, in one embodiment, the connection points of the guide ramp 21 and the front and rear faces of the pin 20 along the front-rear direction x of the refrigerator are respectively provided with arc-shaped transition sections. Similarly, since the rear face of the locking engagement 30 is used to engage with the guide ramp 21, the arc-shaped transition sections at the connection points of the guide ramp 21 and the front and rear faces of the pin 20 along the front-rear direction x of the refrigerator can prevent the formation of sharp corners at the connection points of the front and rear faces of the pin 20 along the front-rear direction x of the refrigerator. This helps to reduce the friction between the rear face of the locking engagement 30 and the guide ramp 21, and facilitates pushing the pin 20 upward along the height direction z of the refrigerator to the upper end face of the locking engagement 30.
[0033] like Figure 4 As shown, the insertion slot 31 includes a first surface 311 and a second surface 312 connected to each other. The first surface 311 is positioned forward along the front-rear direction x of the refrigerator and is used to stop the latch 20 at the rear end face along the front-rear direction x of the refrigerator. It can be understood that when the latch 20 is inserted into the insertion slot 31, the first surface 311 stops the latch 20 at the rear end face along the front-rear direction x of the refrigerator. At this time, when the door is opened, the door causes the first drawer 200 to slide out of the cabinet, and at the same time, the first surface 311 causes the second drawer 300 to slide out of the cabinet simultaneously through the rear end face of the latch 20.
[0034] The second surface 312 is positioned upwards along the height x-direction of the refrigerator. The shape of the second surface 312 is adapted to the shape of the guide slope 21 and is used to fit against the guide slope 21. It can be understood that by adapting the shape of the second surface 312 to the shape of the guide slope 21, the degree of fit between the pin 20 and the inner wall of the insertion groove 31 when it is inserted into the insertion groove 31 can be improved, thereby reducing the wobble between the pin 20 and the locking engagement 30.
[0035] like Figure 4 As shown, the mounting base 10 forms an installation channel 11. The pin 20 includes a rod 22 and a stop head 23. The rod 22 is movably inserted through the installation channel 11 along the height direction of the refrigerator. One end of the rod 22 extends out of the installation channel 11 and is used for insertion into the insertion slot 31. The other end is connected to the stop head 23 and can stop and cooperate with the upper surface of the mounting base 10 along the height direction z of the refrigerator through the stop head 23.
[0036] Understandably, the stop head 23 is used to fix the position of the latch 20. Specifically, when the first drawer 200 and the second drawer 300 are locked, the latch 20 remains engaged with the insertion slot 31 under its own weight. At this time, one end of the rod 22 extends out of the mounting channel 11 and engages with the insertion slot 31, while the other end engages with the upper surface of the mounting base 10 along the height direction z of the refrigerator via the stop head 23. When it is necessary to unlock the first drawer 200 and the second drawer 300, the user can pull the stop head 23 upwards along the height direction z of the refrigerator, thereby disengaging the rod 22 from the insertion slot 31.
[0037] Alternatively, in one embodiment, as Figure 3 As shown, the rod body 22 and the stop head 23 are connected to form a "T" shaped structure.
[0038] The mounting base 10 is installed on the side of the second drawer 300. Specifically, the mounting base 10 includes a main body 12 and flanges 13 connected to both sides of the main body 12. The main body 12 has a groove and is fastened to the second drawer 300. The flanges 13 are detachably connected to the second drawer 300, and the inner wall of the groove and the surface of the second drawer 300 form an installation channel 11. This makes the mounting base 10 simple in structure and easy to manufacture, and facilitates a secure connection between the mounting base 10 and the second drawer 300.
[0039] The flange 13 can be detachably connected to the second drawer 300 using screws.
[0040] Alternatively, in one embodiment, the mounting base 10 is configured as a bent element, and the cross-section of the bent element is "U" shaped.
[0041] like Figure 1 and Figure 4As shown, the locking fitting 30 is installed on the open edge of the first drawer 200 and correspondingly positioned with respect to the mounting base 10, and the locking fitting 30 is configured to extend along the front-rear direction x of the refrigerator. This facilitates the engagement of the locking fitting 30 with the latch 20 while preventing interference between the latch 20 and the first drawer 20.
[0042] Specifically, the locking fitting 30 has a bracket 32 at its bottom along the height direction z of the refrigerator. The bracket 32 has a "C" shaped cross-section and is engaged with the open edge of the first drawer 200 and detachably connected to the first drawer 200 by fasteners. The fasteners can be screws.
[0043] The working principle of the refrigerator drawer linkage device 100 provided in this application is as follows: In the initial state, both the first drawer 200 and the second drawer 300 are located inside the refrigerator body, and the latch 20 is engaged with the insertion slot 31, so the first drawer 200 and the second drawer 300 are locked. When the door is opened, the door causes the first drawer 200 and the second drawer 300 to slide out of the refrigerator body simultaneously. When it is necessary to close the second drawer 300 separately, simply lift the latch 20 upward along the height z direction of the refrigerator, so that the latch 20 disengages from the insertion slot 31, and push the first drawer 200 and the second drawer 300 back into the refrigerator body separately. During the process of pushing the second drawer 300 back into the refrigerator body, the latch 20 automatically falls down under its own weight to the stop head 23 and engages with the upper end face of the mounting base 10. Next, as the door is closed and the second drawer 300 is gradually pushed back into the cabinet, the rear end face of the locking engagement 30 cooperates with the guide slope 21 to push the latch 20 upward along the height direction z of the refrigerator to the upper end face of the locking engagement 30, and slides along the upper end face of the locking engagement 30 until it is inserted into the insertion slot 31 by its own gravity, and the first drawer 200 and the second drawer 300 are locked again.
[0044] This application also provides a refrigerator, which includes a cabinet, a door, a first drawer 200, a second drawer 300, and the refrigerator drawer linkage device 100 described in any of the above embodiments. The first drawer 200 and the second drawer 300 are slidably connected to the cabinet. The first drawer 200 is located below the second drawer 300 along the height z direction of the refrigerator and is installed to the door. The refrigerator drawer linkage device 100 can link the first drawer 200 and the second drawer 300 when the door is opened, so that the second drawer 300 and the first drawer 200 slide out of the cabinet synchronously.
[0045] 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.
[0046] 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.
