Abstract
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 mechanisms are primarily used to link the refrigerator door and drawers. Current methods typically employ either sliding rails or magnetic attraction. However, sliding rails are more complex, prone to accumulating dirt, and require space within the refrigerator, reducing the drawer's usable volume. Magnetic attraction relies on the magnetic force of the magnetic components, but this method is susceptible to magnetic attenuation and insufficient attraction over time, leading to interlocking failure. Furthermore, it's not well-suited for drawers holding heavy items. Utility Model Content
[0003] Therefore, it is necessary to provide a refrigerator linkage device and refrigerator that is simple in structure, not prone to failure, does not occupy too much storage space, and has a stable linkage effect.
[0004] To solve the above-mentioned technical problems, this application provides the following technical solution:
[0005] A refrigerator linkage device for linking the refrigerator door and drawers, the refrigerator linkage device comprising:
[0006] A fixing frame is used to install on the refrigerator door, and the fixing frame has a fixing groove. The fixing groove has a sliding groove on the inner side wall of the drawer along the length direction, and the sliding groove extends along the height direction of the drawer.
[0007] The locking component includes a main body, a slider, and a hook block. The main body is disposed in the fixing groove. The slider is disposed on the side wall of the main body along the length direction of the drawer and is slidably installed in the sliding groove. The hook block is installed on one side of the main body along the height direction of the drawer and extends out of the fixing groove along the depth direction of the drawer. The end of the hook block extending out of the fixing groove has a slot.
[0008] In response to the gravity of the locking member, the slot can engage the drawer, so that the refrigerator door and the drawer are linked; at the same time, in response to an external force, the slider can move in the slide groove along the height direction of the drawer, so that the hook block releases the drawer.
[0009] Understandably, this application, by setting a fixed frame and locking components, places the main body within the fixed groove of the fixed frame installed on the refrigerator door, and allows the slider to slide within the groove. Utilizing the gravity of the locking components, the main body drives the hook block to move along the slider's path within the groove, thus locking the drawer into place and achieving linkage between the refrigerator door and drawer. This linkage device has a relatively simple structure; the locking components are embedded within the fixed frame, minimizing refrigerator space usage. Furthermore, it achieves linkage between the refrigerator door and drawer through a simple structure, avoiding the problem of easily weakened magnetic attraction in magnetic components and improving the device's durability.
[0010] In one embodiment, along the height direction of the drawer, the side of the hook block away from the main body is provided with a protrusion, and the protrusion and the main body form the slot.
[0011] In one embodiment, along the depth direction of the drawer, the protrusion has a first side and a second side disposed opposite to each other, the first side being configured as a first slope and the second side being configured as a second slope;
[0012] Wherein, along the length of the drawer and at the end of the hook block furthest from the main body, the first inclined surface slopes from top to bottom relative to the height of the drawer, and the second inclined surface slopes from bottom to top relative to the height of the drawer.
[0013] Understandably, when the refrigerator door is closed, the first inclined surface guides the drawer to slide into the slot along the first inclined surface. When the drawer and refrigerator door are linked, the second inclined surface can abut against the inner wall of the drawer, increasing the contact area between the refrigerator linkage device and the drawer, making it less likely for the drawer to slide out of the slot, thus improving the reliability of the linkage between the drawer and the refrigerator door.
[0014] In one embodiment, the inclination angle of the first inclined plane is set to 35 degrees-55 degrees, and the inclination angle of the second inclined plane is set to 20 degrees-40 degrees.
[0015] In one embodiment, the number of the slides is set to two, and the two slides are arranged on two opposite inner sidewalls of the fixing groove in the length direction of the drawer;
[0016] The slider is configured as two, and each slider corresponds to one groove.
[0017] Understandably, the symmetrical layout of the double slide rails and double sliders can form a two-way guiding structure, effectively preventing the locking parts from deviating or jamming during movement and improving the accuracy of the locking parts' movement. At the same time, the load can be evenly distributed through the structural settings on both sides, avoiding stress concentration on one side and increasing the upper limit of the refrigerator linkage device's load-bearing capacity for the drawer's weight, thereby expanding the device's application scenarios.
[0018] In one embodiment, the fixing groove is further provided with a protrusion on the inner side wall of the drawer along its length, and the protrusion is provided with a guide surface; and, along the length of the drawer and at the end of the hook block away from the main body, the guide surface is inclined from bottom to top relative to the height direction of the drawer.
[0019] The main body has a mating surface along the length of the drawer, and the mating surface fits into the guide surface.
[0020] Understandably, the protrusions can guide the movement of the locking component through contact with the guide surface, further ensuring the movement trajectory of the locking component, preventing the refrigerator linkage device from deviating or jamming during movement, and increasing the reliability of its linkage.
[0021] In one embodiment, the refrigerator linkage device further includes a push plate, which is disposed on the side of the main body away from the hook block;
[0022] As the hook releases the drawer, the push plate extends out of the fixing slot and pushes the drawer.
[0023] Understandably, when the hook releases the drawer, the push plate extends out of the fixing slot and pushes the drawer to help unlock it, allowing it to be taken out separately for user convenience.
[0024] In one embodiment, the push plate and the main body are configured as an integral structure.
[0025] Understandably, the integrated structure reduces the connection between the top push plate and the main body, improving the stability of their connection and further ensuring the effectiveness of the refrigerator linkage device.
[0026] This application also provides the following technical solutions:
[0027] A refrigerator includes a refrigerator door, a drawer, and a drawer linkage device as described in any of the above embodiments, wherein the drawer and the refrigerator door move synchronously through the drawer linkage device.
[0028] In one embodiment, the fixing frame is fixed to the refrigerator door by threaded connection or pre-embedding before foaming.
[0029] Compared with existing technologies, the refrigerator linkage device and refrigerator described above, by setting a fixed frame and locking components, place the main body in a fixed groove of the fixed frame installed on the refrigerator door, and allow the slider to slide in the groove. Utilizing the gravity of the locking components, the main body drives the hook block to move along the movement path of the slider in the groove, thereby locking the drawer in the groove and achieving linkage between the refrigerator door and the drawer. This linkage device has a relatively simple structure; the locking components are embedded in the fixed frame, which does not occupy excessive refrigerator space. Furthermore, it achieves linkage between the refrigerator door and drawer through a simple structure, avoiding the problem of easily weakened magnetic attraction of magnetic components and improving the durability of the device.

[0043] Please see Figures 1 to 5This application provides a refrigerator, which includes a refrigerator door, a drawer 201 and a refrigerator linkage device 100, wherein the drawer 201 and the refrigerator door move synchronously through the refrigerator linkage device 100.
[0044] Specifically, the refrigerator linkage device 100 includes a fixing frame 10 and a locking member 20: the fixing frame 10 is used to install on the refrigerator door and has a fixing groove 11. The fixing groove 11 has a sliding groove 12 on the inner side wall of the drawer 201 along the length direction y, and the sliding groove 12 extends along the height direction z of the drawer 201; the locking member 20 includes a main body 21, a slider 22 and a hook block 23. The main body 21 is disposed in the fixing groove 11, and the slider 22 is disposed on the side wall of the main body 21 along the length direction y of the drawer 201 and is slidably installed in the sliding groove 11. Inside 2, the hook block 23 is installed on one side of the main body 21 along the height direction z of the drawer 201 and extends out of the fixing groove 11 along the depth direction x of the drawer 201. The end of the hook block 23 extending out of the fixing groove 11 has a slot 24. In response to the gravity of the locking member 20, the slot 24 can engage the drawer 201 so that the refrigerator door is linked with the drawer 201. At the same time, in response to the external force, the slider 22 can move in the slide groove 12 along the height direction z of the drawer 201 so that the hook block 23 releases the drawer 201.
[0045] It needs to be explained that existing refrigerator door and drawer 201 linkage generally uses sliding rails or magnetic structures, while some directly integrate the refrigerator door and drawer 201. Sliding rail structures are relatively complex, difficult to maintain, and require stop components, occupying too much space and reducing the space available for the drawer 201. Magnetic structures experience a weakening of their magnetic attraction after prolonged use, affecting the linkage effect. Directly integrating the refrigerator door and drawer 201 limits the weight capacity of the drawer 201, making it unsuitable for placing heavy items and limiting its application. This application addresses this by setting a fixed frame 10 and a locking element 20. The main body 21 of the locking element 20 is positioned within the fixed groove 11 of the fixed frame 10 installed on the refrigerator door. Utilizing the neutralizing effect of the locking element 20, the main body 21 drives the hook block 23 to engage the drawer 201 within the groove formed between the hook block 23 and the main body 21, thereby achieving linkage between the refrigerator door and drawer 201. This linkage device has a simple structure, is easy to maintain, and does not take up too much space. At the same time, through the setting of the slide groove 12, the slider 22 can move within the slide groove 12 and drive the hook block 23 to realize the linkage and release of the drawer 201. This linkage scheme implemented through a simple structure has a long service life and will not fail after long-term use, that is, its durability is improved compared to the magnetic structure.
[0046] Here, the fixing frame 10 is fixed to the refrigerator door by threaded connection or pre-embedding before foaming. In this way, the fixing frame 10 can be stably fixed on the refrigerator door, ensuring the reliability of the refrigerator linkage device.
[0047] In one embodiment, two slide grooves 12 are provided, which are arranged on two opposite inner sidewalls of the fixed groove 11 in the length direction y of the drawer 201; two sliders 22 are provided, each slider 22 corresponding to one slide groove 12. It can be understood that the symmetrical arrangement of the double slide grooves 12 and the double sliders 22 can form a bidirectional guiding structure, effectively preventing the locking member 20 from deviating or jamming during movement, and improving the accuracy of the movement of the locking member 20. At the same time, the load can be evenly distributed through the structural arrangement on both sides, avoiding stress concentration on one side, and increasing the upper limit of the load-bearing capacity of the refrigerator linkage device 100 on the drawer 201, thereby expanding the application scenarios of the device.
[0048] like Figure 2 As shown, the fixing groove 11 is provided with a protrusion 13 on the inner side wall of the drawer 201 along the length direction y, and a guide surface 131 is provided on the protrusion 13; furthermore, at the end of the drawer 201 along the length direction y and away from the main body 21, the guide surface 131 is inclined from bottom to top relative to the height direction z of the drawer 201; the main body 21 is provided with a mating surface 211 along the length direction y of the drawer 201, and the mating surface 211 fits against the guide surface 131. In this way, the contact between the guide surface 131 on the protrusion 13 and the mating surface 211 allows the main body to move along the correct movement trajectory, ensuring the accuracy of the linkage process. That is, the protrusion 13 guides the locking member 20, avoiding jamming of the refrigerator linkage device 100 due to movement deviation during movement, thus improving the user experience of the device.
[0049] like Figure 1 and Figure 3 As shown, along the height direction z of drawer 201, the hook block 23 has a protrusion 231 on the side away from the main body 21, and the protrusion 231 and the main body 21 form a slot 24.
[0050] Furthermore, along the depth direction x of drawer 201, protrusion 231 has a first side surface 2311 and a second side surface 2312 arranged opposite to each other. The first side surface 2311 is configured as a first inclined surface, and the second side surface 2312 is configured as a second inclined surface. Specifically, at the end of drawer 201 along its length direction y and at the end of hook block 23 furthest from the main body 21, the first inclined surface slopes sequentially from top to bottom relative to the height direction z of drawer 201, and the second inclined surface slopes sequentially from bottom to top relative to the height direction z of drawer 201. Thus, when the refrigerator door is closed, the first inclined surface guides drawer 201 to slide into the slot 24. When drawer 201 is linked with the refrigerator door, the second inclined surface abuts against the inner wall of drawer 201, increasing the contact area between the refrigerator linkage device 100 and drawer 201, thereby increasing the friction between drawer 201 and the second inclined surface, making it less likely for drawer 201 to slide out of the slot 24, thus improving the reliability of the linkage between drawer 201 and refrigerator door.
[0051] Here, the side corresponding to the second inclined surface is the mating surface 2011 of the drawer 201. When the drawer 201 is linked with the refrigerator door, the second inclined surface and the mating surface 2011 are mated together.
[0052] In one embodiment, the inclination angle of the first inclined plane is set to 35 degrees to 55 degrees, and the inclination angle of the second inclined plane is set to 20 degrees to 40 degrees.
[0053] Here, the inclination angle of the first slope can be set to 35°, 40°, 45°, 50°, or 55°; the inclination angle of the second slope can be set to 20°, 25°, 30°, 35°, or 40°. Of course, the values of the inclination angles of the first and second slopes are not limited to the angles mentioned above. The specific value of the inclination angle of the first slope can be determined according to the actual situation; the specific value of the inclination angle of the second slope can be set according to the actual inclination angle of the contact surface of drawer 201.
[0054] Please continue to refer to this. Figures 3 to 5The side of the main body 21 facing the drawer 201 is set as an inclined surface 25, and the inclination angle of the inclined surface 25 is the same as the inclination angle of the first inclined surface. The refrigerator linkage device 100 also includes a push plate 30, which is located on the side of the main body 21 away from the latch block 23. When the latch block 23 releases the drawer 201, the push plate 30 extends out of the fixing groove 11 and pushes the drawer 201. Thus, when the latch block 23 releases the drawer 201, the push plate 30 extends out of the fixing groove 11 and pushes the drawer 201, assisting in unlocking the drawer 201 so that it can be taken out independently for user convenience. Furthermore, the inclination angle of the inclined surface 25 is set to be the same as the inclination angle of the first inclined surface, so that when the drawer 201 is linked with the refrigerator door, the push plate 30 is placed within the fixing groove 11, so as not to affect the linkage effect of the drawer 201.
[0055] In one embodiment, the push plate 30 and the main body 21 are configured as an integral structure. It is understood that the integral structure reduces the connection structure between the push plate 30 and the main body 21, improves the stability of the connection between the two, and further ensures the effectiveness of the refrigerator linkage device 100.
[0056] 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.
[0057] 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.
