Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of refrigerators, in particular to a refrigerator linkage device and a refrigerator. BACKGROUND

[0002] In the use of refrigerators in modern families, the design and convenience of the freezer compartment have always been the focus of users. In the structure of the traditional refrigerator freezer compartment, the relationship between the door and the internal drawer is relatively fixed, and the drawer usually needs to be pulled out separately after the door is opened, which is relatively cumbersome to operate.

[0003] In order to improve the convenience of use, some refrigerators have tried linkage design of the freezer door and the drawer. At present, part of the linkage design is forced, that is, as long as the freezer door is opened, the drawer will be inevitably taken out. This way does not meet the actual needs of users in some cases, for example, when the user only wants to check the items in the freezer compartment without pulling out the drawer, forcibly taking out the drawer not only increases the complexity of operation, but also may cause the items to fall or be disordered due to accidental taking out of the drawer. Although some other linkage designs provide certain choices, they need to manually separate the drawer door and the freezer door, which is laborious and time-consuming. CONTENT OF THE UTILITY MODEL

The term "and / or" used in the specification of the present application includes any and all combinations of one or more of the associated listed items.

[0046] Referring to Figures 1 to 6 The present application provides a refrigerator linkage device 100, which is installed on a refrigerator door 200 and used for linkage between the refrigerator door 200 and a drawer 10 to enable a user to select whether to open the drawer 10 simultaneously when opening the refrigerator door 200.

[0047] Specifically, referring to Figures 1 to 6 The refrigerator linkage device 100 includes a housing 20, a magnetic linkage mechanism 30, an operating mechanism 40, and a locking mechanism 50. The housing 20 is used to be installed on the refrigerator door 200. The magnetic linkage mechanism 30 is installed in the housing 20 along a first direction x and has a first position and a second position. A cooperating part 11 is provided on the drawer 10. The magnetic linkage mechanism 30 is used to cooperate with the cooperating part 11 at the first position to magnetically attract and lock the refrigerator door 200 and the drawer 10 together, or to be misaligned with the cooperating part 11 at the second position to release the magnetic attraction between the refrigerator door 200 and the drawer 10 and separate them. The operating mechanism 40 is installed on the housing 20 and can move along a second direction y. The operating mechanism 40 can push the magnetic linkage mechanism 30 to move along the first direction x and switch the position between the first position and the second position. The operating mechanism 40 is provided with an unlocking position and a locking position. The first direction x is arranged at an angle with the second direction y. The locking mechanism 50 is installed in the housing 20 and moves with the operating mechanism 40. The locking mechanism 50 can lock the operating mechanism 40 at the locking position to make the magnetic linkage mechanism 30 at the first position, or unlock the operating mechanism 40 at the unlocking position to make the magnetic linkage mechanism 30 at the second position. In this way, by providing the operating mechanism 40 and the magnetic linkage mechanism 30, the operating mechanism 40 is used to switch the magnetic linkage mechanism 30 between the first position and the second position, so as to magnetically attract or separate the magnetic linkage mechanism 30 and the cooperating part 11, thereby realizing the switching between the unlocking position and the locking position. In this way, the user can select linkage or no linkage between the drawer 10 and the refrigerator door 200 according to his own needs, which is more convenient and flexible to use. At the same time, since only the operating mechanism 40 needs to be operated to make the magnetic linkage mechanism 30 move and cooperate with the cooperating part 11, the separation between them can be realized, and the operation is also more convenient.

[0048] Here, the cooperating part 11 can be a permanent magnet or a material that can be magnetized, such as a piece of iron, an iron alloy, etc. Of course, it is not limited to this, and the cooperating part 11 can also be provided as an electromagnet.

[0049] In an embodiment, referring to Figure 4As shown, the magnetic linkage mechanism 30 comprises a linkage seat 31 and a magnetic piece 32, the linkage seat 31 is installed in the shell 20 and provided with a passage 33 along the first direction x, the magnetic piece 32 is arranged in the passage 33 and can move in the passage 33 in response to the movement of the movable block 42; wherein the magnetic piece 32 is magnetically connected with the cooperating piece 11 at the first position, at this time the drawer 10 can be linked with the refrigerator door 200; the magnetic piece 32 is dislocated from the cooperating piece 11 and separated from the cooperating piece 11 at the second position, at this time the magnetic connection between the magnetic piece 32 and the cooperating piece 11 is cut off, so that the magnetic connection between the drawer 10 and the refrigerator door 200 is separated.

[0050] In the embodiment, the linkage seat 31 is installed at the side wall of the shell 20, and the magnetic piece 32 is a magnet.

[0051] In an embodiment, the magnetic linkage mechanism 30 further comprises a first elastic piece 34, the first elastic piece 34 is arranged in the passage 33 and one end is limited to the linkage seat 31, and the other end is used to abut against the magnetic piece 32. The first elastic piece 34 provides a restoring force for the magnetic piece 32, ensures that the magnetic piece 32 can return to the initial position when losing external force, and improves the reliability and stability of the refrigerator linkage device 100.

[0052] As preferred, the linkage seat 31 is provided with a fixing column 311, and the first elastic piece 34 is sleeved on the fixing column 311, so that the fixing column 311 is used to limit the first elastic piece 34. Here, the first elastic piece 34 is a spring or a component with elastic function.

[0053] In an embodiment, the number of the magnetic linkage mechanism 30 is configured as two, and the two magnetic linkage mechanisms 30 are symmetrically arranged on both sides of the movable block 42 along the first direction x and can synchronously respond to the movement of the movable block 42. In this way, by symmetrically arranging the two magnetic linkage mechanisms 30, the balance and stability of magnetic attraction and separation are improved, and the linkage between the refrigerator door 200 and the drawer 10 is more reliable.

[0054] Please continue to refer to Figures 4 to 6The operating mechanism 40 comprises an operating handle 41 and a movable block 42. The operating handle 41 is mounted on the shell 20 and can move in the second direction y. One end of the operating handle 41 extends into the shell 20, and the other end is located outside the shell 20. The movable block 42 is arranged in the shell 20, and a track groove 421 is formed in the movable block 42. The track groove 421 comprises a locking groove 4211 and an unlocking groove 4212 which are in communication with each other. The locking mechanism 50 can be matched with the locking groove 4211 to lock the operating mechanism 40 or matched with the unlocking groove 4212 to unlock the operating mechanism 40. In response to the movement of the operating handle 41, the movable block 42 can push the magnetic linkage mechanism 30 to move in the first direction x. The cooperation of the operating handle 41 and the movable block 42 enables the user to realize the position switching of the magnetic linkage mechanism 30 through the movement of the operating handle 41, which is simple and convenient. Moreover, the design of the track groove 421 ensures that the locking mechanism 50 can accurately switch between the locking and unlocking positions.

[0055] Further, the operating handle 41 comprises a pressing handle 411 and a limiting piece 412. One end of the pressing handle 411 extends into the shell 20, and the other end is located outside the shell 20. The cooperation of the operating handle 41 and the limiting piece 412 makes the movement of the operating handle 41 more stable. The limiting piece 412 is limited in cooperation with the shell 20 to prevent the operating handle 41 from moving excessively or separating from the shell 20.

[0056] Specifically, an inclined surface 422 is arranged on the movable block 42. In response to the movement of the operating handle 41, the inclined surface 422 can convert the movement of the movable block 42 in the second direction y into the movement of the magnetic linkage mechanism 30 in the first direction x. In this way, the conversion from the movement of the operating handle in the second direction y to the movement of the magnetic linkage mechanism 30 in the first direction x is realized by arranging the inclined surface 422, which improves the space utilization and movement transmission efficiency of the refrigerator linkage device 100.

[0057] In the present embodiment, the limiting piece 412 is located in the shell 20 and connected with the pressing handle 411, and can be limited in cooperation with the shell 20.

[0058] As shown in Figures 4 to 6 The locking mechanism 50 comprises a locking seat 51, a locking rod 52 and a second elastic member 53. The locking seat 51 is mounted on the shell 20. One end of the locking rod 52 is movably connected to the locking seat 51, and the other end is located in the track groove 421 and can move along the track groove 421 to the locking groove 4211 or the unlocking groove 4212. One end of the second elastic member 53 is limited in the locking seat 51, and the other end is used to cooperate with the movable block 42.

[0059] The working principle of the refrigerator linkage device 100 in the present application is described as follows:

[0060] When the refrigerator door 200 and the drawer 10 are in linkage state, the magnetic linkage mechanism 30 is in the first position, when it is needed to make the refrigerator door 200 and the drawer 10 not in linkage state, the press handle 411 is pressed, the operating handle 41 drives the movable block 42 to move downward along the second direction y, the locking rod 52 moves along the track groove 421 to the locking groove 4211 and locks the movable block 42, in the process, the inclined surface 422 of the movable block 42 can push the magnetic linkage mechanism 30 to move from the first position to the second position along the first direction x, so that the magnetic member 32 is separated from the matched member 11, and the purpose of separating the refrigerator door 200 and the drawer 10 is achieved.

[0061] When it is needed to make the refrigerator door 200 and the drawer 10 in linkage state, the user presses the press handle 411 again, the locking rod 52 moves along the track groove 421 from the locking groove to the unlocking groove 4212 and unlocks the movable block 42, the movable block 42 moves upward along the second direction y under the action of the second elastic member 53, in the process, the magnetic linkage mechanism 30 moves from the second position to the first position along the first direction x, so that the magnetic member 32 is magnetically attracted to the matched member 11, and the purpose of making the refrigerator door 200 and the drawer 10 in linkage state is achieved.

[0062] Please refer to Figure 1 The refrigerator provided by the present application comprises a refrigerator door 200, a drawer 10, a cabinet 300 and the refrigerator linkage device 100 as any one of the above embodiments, the refrigerator linkage device 100 is installed in the cavity 210 on the refrigerator door 200, and is used for linkage between the refrigerator door 200 and the drawer 10.
