[0048] This application provides a refrigerator door lock assembly; for example, please refer to [link to example]. Figures 1-4 , Figure 1 This is a schematic diagram of the structure of the door lock assembly provided in an embodiment of this application. Figure 2 This is a schematic diagram of the structure of a refrigerator provided in an embodiment of this application. Figure 3 for Figure 2 The image shown is an enlarged view of the refrigerator when the door lock assembly is in the first state. Figure 4 for Figure 2 The image shows an enlarged view of the refrigerator with the door lock assembly in the second state. The refrigerator 10 includes a door lock assembly 100, a cabinet 200, and a first door 300. One of the cabinet 200 and the first door 300 has a first cavity 310 formed inside, and the other has a second cavity 210 formed inside. The first cavity 310 has a first opening (not shown) communicating with the outside. The door lock assembly 100 includes a lock base 110 and a latch assembly 120.
[0049] The lock seat 110 is disposed in the second cavity 210; the lock tongue assembly 120 includes a rotating member 121 and a lock hook 122. The rotating member 121 is rotatably connected to the first cavity 310, and the lock hook 122 is fixedly connected to the rotating member 121. The rotating member 121 is used to rotatably drive the lock hook 122 to extend to the outside through the first opening or to retract into the first cavity 310. When the rotating member 121 rotates to the first position, the lock hook 122 is adapted to cooperate with the lock seat 110 to lock the first door 300.
[0050] It should be noted that the presence of a first cavity 310 inside one of the housing 200 and the first door 300, and a second cavity 210 inside the other, indicates the following two embodiments: the first is that the first cavity 310 is disposed on the first door 300, and the second cavity 210 is disposed on the housing 200; the second is that the first cavity 310 is disposed on the housing 200, and the second cavity 210 is disposed on the first door 300.
[0051] Understandably, the locking hook 122 has a first state of extending outwards and a second state of retracting into the first cavity 310. In practical applications, when the user needs to lock the first door 300, the rotating member 121 can be rotated to the first position to drive the locking hook 122 into the first state of extending outwards. Then, the first door 300 can be closed, so that the locking hook 122 is locked in the lock seat 110, thereby locking the first door 300 onto the housing 200. When the user does not need to lock the first door 300, the locking hook 122 can be rotated to the second state of retracting into the first cavity 310. In this way, the locking hook 122 will not be exposed to the outside and cause a safety hazard.
[0052] The door lock assembly 100 of the refrigerator 10 provided in this application embodiment, by setting the lock base 110 in the second cavity 210 and having the lock hook 122 in a first state extending to the outside and a second state retracted into the first cavity 310, allows the lock hook 122 to be stored in the first cavity 310 when the user does not need to lock the door. This prevents the lock hook 122 and lock base 110 from being exposed to the outside, thereby avoiding the safety hazard of the door lock assembly 100 causing punctures or scratches. Furthermore, the door lock assembly 100 of this application has a simple structure, is easy to operate, and can provide users with a good user experience.
[0053] In some embodiments, the refrigerator 10 further includes a second door 400, on which a slot 410 is provided, and a first cavity 310 also has a second opening 311 facing the second door 400. The rotating member 121 includes a driving part 1211. The door lock assembly 100 also includes a pin 123 movably disposed in the first cavity 310. One end of the pin 123 abuts against the driving part 1211, and the other end passes through the second opening 311. The driving pin 123 for rotating the driving part 1211 extends to the outside or retracts into the first cavity 310 through the second opening 311. When the rotating member 121 rotates to the first position, the pin 123 is adapted to insert into the slot 410 to lock the second door 400.
[0054] Understandably, the latch 123 can be driven by the drive unit 1211 to move along the extension direction of the second opening 311, thus having a first state of extending outward and a second state of retracting into the first cavity 310. In practical applications, when the user needs to lock the first door 300 and the second door 400, the slot 410 can be aligned with the second opening 311, and then the rotating member 121 can be rotated to the first position to drive the latch 123 to insert into the slot 410; after the rotating member 121 is rotated to the first position, the locking hook 122 also enters the first state of extending outward. By closing the first door 300, both the first door 300 and the second door 400 can be locked onto the housing 200. When the user does not need to lock the first door 300 and the second door 400, the latch 123 can be driven into the second state of retracting into the first cavity 310 and the locking hook 122 can be rotated to the second state of being retracted into the first cavity 310 by rotating the rotating member 121. In this way, a single locking tongue assembly 120 can simultaneously lock and unlock multiple refrigerator doors 10, which not only simplifies operation but also reduces material consumption and saves costs.
[0055] For example, please refer to Figure 5 , Figure 5 This is a schematic diagram of the structure connecting the rotating component and the locking hook provided in an embodiment of this application. The rotating component 121 is adapted to rotate about a first axis 1212; the driving part 1211 includes a guide slope 1211a disposed around the first axis 1212. Along the circumference of the first axis 1212, the guide slope 1211a is inclined from the direction close to the first axis 1212 to the direction away from the first axis 1212, and the pin 123 is adapted to abut against the guide slope 1211a. Optionally, as shown... Figure 5As shown, the rotating component 121 includes a cylindrical rotating portion 1213, the height direction of which is the same as the extension direction of the first axis 1212. The rotating portion 1213 is rotatably connected to the first cavity 310 and is adapted to rotate about the first axis 1212; a locking hook 122 is fixed to the rotating portion 1213; and a driving portion 1211 is disposed on the circumferential side wall of the rotating portion 1213.
[0056] In practical applications, the user can rotate the rotating component 121 to make the pin 123 slide relative to the guide slope 1211a, thereby driving the pin 123 to extend outward through the second opening 311 or retract into the first cavity 310. When the rotating component 121 rotates in the first direction, the pin 123 slides from the end of the guide slope 1211a near the first axis 1212 to the end of the guide slope 1211a away from the first axis 1212, that is, the pin 123 moves in the direction away from the first axis 1212 and is in the first state of extending outward from the first cavity 310. When the rotating component 121 rotates in the second direction, the pin 123 slides from the end of the guide slope 1211a away from the first axis 1212 to the end of the guide slope 1211a near the first axis 1212, that is, the pin 123 moves in the direction of moving towards the first axis 1212 and is in the second state of retracting into the first cavity 310.
[0057] In some embodiments, the drive unit 1211 further includes a limiting rib 1211b disposed around the guide slope 1211a, the limiting rib 1211b being used to limit the pin 123. This prevents the pin 123 from disengaging from the guide slope 1211a when sliding relative to it, thereby improving the stability of the contact between the pin 123 and the drive unit 1211 and ensuring the stable performance of the door lock assembly 100.
[0058] Optionally, such as Figures 2-4As shown, the first cavity 310 is located in the first door 300, and the second door 400 is located above the first door 300. When the rotating member 121 rotates from the first position to the second position, the latch 123 retracts into the first cavity 310 due to its own weight. Since the first cavity 310 is located in the first door 300, the second cavity 210 is located in the housing 200. Since the second door 400 is located above the first door 300, the second opening 311 faces upward, and the slot 410 faces downward. The latch 123 is adapted to move upward relative to the second opening 311 to insert into the slot 410 to lock the second door 400; or the latch 123 is adapted to move downward relative to the second opening 311 to retract into the first cavity 310 to unlock the second door 400. In some other embodiments, the second door 400 may be located below the first door 300. When the rotating member 121 rotates from the first position to the second position, the driving part 1211 drives the pin 123 to retract into the first cavity 310. When the rotating member 121 rotates from the second position to the first position, the pin 123 is inserted into the slot 410 by its own weight.
[0059] In one parallel embodiment, the latch assembly 120 further includes a spring, which is sleeved on the pin 123 and its two ends are fixedly connected to the pin 123 and the first cavity 310, respectively. When the rotating member 121 rotates from the second position to the first position, it drives the pin 123 to insert into the slot 410, and the spring undergoes elastic deformation. When the rotating member 121 rotates from the first position to the second position, the pin 123 is retracted into the first cavity 310 by the elastic force of the spring.
[0060] In some embodiments, please refer to Figure 6 , Figure 6 This is an exploded view of the latch assembly provided in an embodiment of this application. The latch assembly 120 also includes a first mounting bracket 124, which is fixed within the first cavity 310. One of the rotating member 121 and the first mounting bracket 124 is provided with a pivot, and the other is provided with a pivot hole. The pivot is adapted to mate with the pivot hole so that the rotating member 121 is rotatably connected to the first cavity 310. Optionally, the pivot hole is formed on the rotating member 121, for example, in the rotating part 1213; the pivot is provided on the first mounting bracket 124.
[0061] In some embodiments, such as Figures 2-3 As shown, the first cavity 310 also has a third opening (not shown) communicating with the outside. The latch assembly 120 also includes a knob 125, which is located on the outside and is fixedly connected to the rotating member 121 and / or the locking hook 122 through the third opening. In this way, the user can rotate the knob 125 from the outside to drive the rotating member 121 inside the first cavity 310 to rotate, thereby completing the locking and unlocking operation.
[0062] In some embodiments, please refer to Figures 7-9 , Figure 7 This is an exploded view of the lock base provided in an embodiment of this application. Figure 8 This is a schematic diagram of the lock seat in the first state according to an embodiment of this application. Figure 9 This is a schematic diagram of the lock seat in a second state according to an embodiment of this application. The lock seat 110 includes a first crank arm 111, a second crank arm 112, and an elastic member 113. The first crank arm 111 includes a first front end 1111 and a first rear end 1112; the second crank arm 112 includes a second front end 1121 and a second rear end 1122. The first rear end 1112 and the second rear end 1122 are rotatably connected to the second cavity 210. The first front end 1111 and the second front end 1121 are disposed opposite to each other and form a limiting groove 1113 communicating with the outside between them. The limiting groove 1113 is adapted to cooperate with the head of the locking hook 122. The two ends of the elastic member 113 are respectively connected to the first crank arm 111 and the second cavity 210. The lock seat 110 has a first state in which the first front end 1111 and the second front end 1121 are separated from each other due to external force and the elastic member 113 is deformed, and a second state in which the first front end 1111 and the second front end 1121 are brought closer to each other due to the elastic force of the elastic member 113.
[0063] The elastic element 113 can be a spring, a sheet, or other component with elastic force. The lock seat 110 may also include a second mounting bracket 114, which is fixedly installed in the second cavity 210. The first rear end 1112 and the second rear end 1122 are rotatably connected to the second mounting bracket 114, for example, through a rotating shaft structure.
[0064] In practical application, when the head of the locking hook 122 is placed in the first relative position of the limiting groove 1113, the first front end 1111 and the second front end 1121 are pushed away from each other by the force of the head of the locking hook 122, thereby widening the opening of the limiting groove 1113 and allowing the head of the locking hook 122 to continue to extend into the limiting groove 1113; when the head of the locking hook 122 is placed in the second relative position of the limiting groove 1113, the head of the locking hook 122 stops applying the pushing force to the first front end 1111 and the second front end 1121 because it is fully inserted into the limiting groove 1113, thereby the first front end 1111 and the second front end 1121 are brought closer to each other by the elastic force of the elastic member 113, the opening of the limiting groove 1113 returns to its original state, and forms a limit on the head of the locking hook 122 in the exit direction of the locking hook 122, so as to lock the locking hook 122.
[0065] In some embodiments, the second cavity 210 has a fourth opening communicating with the outside. The door lock assembly 100 also includes an unlocking member 130, which is adapted to be movably extended into the second cavity 210 through the fourth opening. The unlocking member 130 has a first form that drives the lock seat 110 into a first state under external force. Thus, the user can use the unlocking member 130 to drive the lock seat 110 into the first state, thereby widening the opening of the limiting groove 1113 and allowing the head of the lock hook 122 to exit from the limiting groove 1113, thereby unlocking the first door 300. When the unlocking member 130 is lost, the user can also use common everyday items such as tweezers or a stick to insert into the second cavity 210 and pry the first front end 1111 and the second front end 1121 apart. For example, please refer to [link to example]. Figure 10 , Figure 10 This is a schematic diagram of the unlocking component provided in an embodiment of this application. The unlocking component 130 includes two pry bars 131, which are pivotally connected.
[0066] The door lock assembly 100 of the refrigerator 10 provided in this application embodiment, by setting the lock base 110 in the second cavity 210 and having the lock hook 122 in a first state extending to the outside and a second state retracted into the first cavity 310, allows the lock hook 122 to be stored in the first cavity 310 when the user does not need to lock the door. This prevents the lock hook 122 and lock base 110 from being exposed to the outside, thereby avoiding the safety hazard of the door lock assembly 100 causing punctures or scratches. Furthermore, the door lock assembly 100 of this application has a simple structure, is easy to operate, and can provide users with a good user experience.
[0067] This application embodiment also provides a refrigerator 10, which can be a single-door refrigerator or a multi-door refrigerator such as a French door refrigerator, a side-by-side refrigerator, or a cross-door refrigerator. For example,... Figures 3-4 As shown, the refrigerator 10 includes a door lock assembly 100, a cabinet 200, and a first door 300 as described in any of the above embodiments. A first cavity 310 is formed inside the cabinet 200 and the first door 300, and a second cavity 210 is formed inside the other. The first cavity 310 has a first opening communicating with the outside. The first door 300 and the cabinet 200 are interlocked by the door lock assembly 100.
[0068] The refrigerator 10 provided in this application embodiment, by respectively providing a first cavity 310 and a second cavity 210 on the door and the cabinet 200, and placing the lock seat 110 in the second cavity 210, and by having the lock hook 122 in a first state extending to the outside and a second state retracted into the first cavity 310, allows the lock hook 122 to be stored inside the first cavity 310 when the user does not need to lock the door. This prevents the lock hook 122 and lock seat 110 from being exposed to the outside, thereby avoiding the safety hazard of the door lock assembly 100 causing punctures or scratches. Furthermore, the door lock assembly 100 of this application has a simple structure, is easy to operate, and can provide users with a good user experience.
