[0032] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0033] like Figures 1 to 3 As shown, in an illustrative embodiment of a vertical refrigerator with a built-in lock body of the utility model, the vertical refrigerator with a built-in lock body includes a cabinet body 1, and a cabinet door 2 is installed on the cabinet body 1. Goods are placed in a storage space 11 inside the cabinet body 1. By opening the cabinet door 2, the goods can be placed in the storage space 11 or taken out from the storage space 11, and by closing the cabinet door 2, the goods can be sealed in the storage space 11.
[0034] The cabinet body 1 is provided with a lock body 3, which is located in the storage space 11 of the cabinet body 1. When the cabinet door 2 is closed, the lock hook 21 provided on the cabinet door 2 is clamped on the lock tongue 31 provided on the lock body 3. The lock tongue 31 blocks the lock hook 21 from moving outward, thereby preventing the cabinet door 2 from moving in the opening direction, thereby locking the cabinet door 2, keeping the cabinet door 2 closed and sealing the storage space 11. The lock body 3 controls the lock tongue 31 to be retracted, thereby disengaging from the insertion slot 25 of the lock hook 21, thereby eliminating the limit on the lock hook 21, allowing the cabinet door 2 to move in the opening direction, and opening the refrigerator.
[0035] In the above-mentioned illustrative embodiment, the vertical refrigerator with built-in lock body arranges the lock body in the storage space 11 for storing goods, so that after the cabinet door 2 closes the storage space 11 and is locked by the lock body, the lock body is also locked in the storage space 11, avoiding the lock body from being exposed to the outside, making it difficult to be damaged, and improving the safety of the goods in the refrigerator; in addition, since the lock body is arranged in the internal space, there is no need to set a light box to install the lock body, the refrigerator eliminates the light box to reduce the cost, and only one lock body needs to be set to maintain good security, and the cost of setting the door lock is also relatively low, which solves the problem of high cost and insufficient security of the current smart refrigerator lock body.
[0036] The lock body 3 has a driving element 5 and a control circuit board 6. The driving element 5 has a valve body 51. The valve body 51 has an electromagnet. The lock tongue 31 is slidably mounted in a through hole 33 provided in the lock body 3. The electromagnetic shaft 52 fixedly mounted at its inner end is slidably mounted in the valve body 51, so that the electromagnet drives the electromagnetic shaft 52 to move axially through the electromagnetic force, thereby driving the lock tongue 31 to extend and retract, so that the lock tongue 31 is inserted into the lock slot of the lock hook 21 or is pulled out of the lock slot. The control circuit board 6 is electrically connected to the driving element 5 to control the driving element 5 to extend and retract the lock tongue 31.
[0037] The lock body 3 has a lock housing 34, one side of which is open so that the lock body components such as the lock tongue 31, the drive element 5, and the control circuit board 6 can be installed therein, and the lock housing 34 is closed on its open side by a side plate 36 installed by bolts.
[0038] In some embodiments, the cabinet body 1 has a cabinet opening 12, and the cabinet door 2 is installed on the cabinet opening 12, so that by closing or opening the cabinet opening 12, the refrigerator is opened to take out goods or closed to seal the goods in the storage space 11. The lock body 3 is installed on the cabinet opening 12, so that the lock body 3 is located on the inner wall facing the storage space 11, and the lock body 3 is located at the front side close to the cabinet door 2, so that the lock hook 21 is easier to align with the lock tongue 31, and then the lock tongue 31 is more quickly and accurately limited, ensuring the stability of the door lock function. In addition, since the lock body 3 is close to the cabinet door 2, the lock hook 21 can be clamped onto the lock tongue 31 with a shorter length, which reduces the material used for the lock hook 21 and reduces the cost of the lock hook 21. When the cabinet door 2 is installed on the cabinet body 1 in a hinged manner, the shorter lock hook 21 has a smaller angle deflection as the cabinet door 2 is flipped, so that the lock hook 21 can maintain alignment with the lock tongue 31 within a wider range when the cabinet door 2 is flipped and approaches the lock tongue 31, thereby ensuring that the lock tongue 31 can clamp the lock hook 21 well and ensure the stability of the door lock function.
[0039] In some embodiments, the cabinet door 2 includes a frame 22 and a transparent glass 23 mounted on the frame 22, so that the refrigerator becomes a display cabinet, which is convenient for displaying the goods in the refrigerator. At the same time, the lock body 3 is located on the inner side of the frame 22, so that the lock body 3 is blocked by the frame 22, which increases the difficulty of observing the lock body 3 from the outside to the inside, thereby further increasing the concealment of the lock body 3 and improving the safety of the door lock structure.
[0040] In some embodiments, a sealing strip 24 is provided on the inner surface of the cabinet door 2, and when the sealing strip 24 is attached to the cabinet body 1, it surrounds the lock body 3. The sealing strip 24 seals the gap between the cabinet door 2 and the cabinet body 1, improves the heat preservation performance of the refrigerator, prevents the cold energy inside the refrigerator from being lost, and realizes energy saving of the refrigerator. At the same time, it can surround the lock body 3 to prevent people from damaging the lock body 3 through the gap between the cabinet body 1 and the cabinet door 2 or contacting the lock hook 21 and the lock tongue 31 to unlock, thereby further improving the safety of the door lock device.
[0041] In some embodiments, one side of the cabinet door 2 is hinged on the cabinet body 1, and the lock hook 21 is installed on the other side of the cabinet door 2. If the cabinet door 2 is opened and closed by pushing and pulling, the lock body 3 only limits its movement in the push-pull direction. Under the action of external force, the gap between the cabinet body 1 and the cabinet door 2 can be expanded, thereby causing the risk of the lock body 3 being damaged or unlocked through the gap. When the cabinet door 2 is opened sideways, when the cabinet door 2 is closed, the hinged side can always be close to the cabinet body 1, and it is difficult to produce a gap under the action of external force. The other side is locked by the lock body 3, so that when only one lock body 3 is set, it is ensured that the goods are firmly enclosed inside it, which improves the safety of the goods in the refrigerator and reduces the configuration cost of the door lock.
[0042] In some embodiments, a lock port 32 is provided on the lock shell of the lock body 3, and the lock hook 21 extends into the lock shell through the lock port 32 and engages with the lock tongue 31 in the lock shell. The connection between the lock tongue 31 and the lock hook 21 is hidden in the lock shell, and it is difficult for tools to extend from the outside into the lock shell and disengage the lock hook 21 from the engagement with the lock tongue 31, which increases the difficulty of abnormal unlocking and improves safety. In addition, the setting of the lock port 32 and the extension method of the lock tongue 31 ensure that the lock tongue 31 is always inside the lock shell, avoiding freezing due to its extension into the storage space outside the lock shell, thereby ensuring that the lock tongue 31 can be smoothly extended and retracted, and the door lock function is maintained normally when the lock body 3 is inside the refrigerator.
[0043] In some embodiments, a partition block 35 is installed in the lock housing 34 . The partition block 35 is located at one side of the lock port 32 . A through hole 33 is formed on the partition block 35 . The lock tongue 31 is slidably installed in the through hole 33 .
[0044] The partition block 35 closes the space inside the lock shell 34 away from the lock port 32. Since the driving element 5 and the control circuit board 6 are installed in this space, the closing of the partition block 35 prevents water vapor from entering and causing damage to the electrical components. In addition, the partition block 35 is provided with a through hole 33 as a guide for the extension and retraction of the lock tongue 31, and the through hole 33 is not facing the lock port 32 on one side, so that after the water vapor in the refrigerator enters the lock shell 34 through the lock port 32, it needs to turn to enter the gap between the through hole 33 and the lock tongue 31, which increases the difficulty of water vapor entering and reduces the probability that the water vapor enters the through hole 33 and freezes, causing the lock tongue 31 to be unable to smoothly extend and retract. Furthermore, due to the cabinet door 2 blocking the lock opening 32, the cabinet door 2 blocks the lock tongue 31 in the moving direction of the lock hook 21, and the lock hook 21 itself blocks it on the side of its moving direction, ultimately making the lock tongue 31 covered in two directions, further increasing the difficulty of external tools reaching into and prying the lock tongue 31, thereby increasing the difficulty of abnormal unlocking and improving safety.
[0045] A heating coil is installed in the lock body 3 to heat the lock tongue 31 to prevent the lock tongue 31 from freezing and ensure that the lock tongue 31 can be opened and closed smoothly in the cold environment of the storage space 11. In order to further prevent water vapor from entering and causing damage to electrical components, a sealing ring 37 is installed in the through hole 33 or between the partition block 35 and the lock tongue 31 to block water vapor from entering.
[0046] In some embodiments, the lock tongue 31 is arranged vertically and is inserted into the insertion slot of the lock hook 21 from top to bottom. When the lock body 3 adopts an electronic door lock structure and a power failure occurs, the lock tongue 31 can maintain the engagement with the lock hook 21 by its gravity, thereby keeping the cabinet door 2 locked, and avoiding the door lock failure caused by power failure of the refrigerator.
[0047] Based on the vertical refrigerator with built-in lock body 3, the utility model also provides a double-door refrigerator, such as Figure 4 As shown, the double-door refrigerator includes a cabinet body 1 having a cabinet opening 12. A center beam 4 installed on the cabinet body 1 divides the cabinet opening 12 into a first cabinet opening 12A and a second cabinet opening 12B on the left and right. Cabinet doors 2 are installed on the first cabinet opening 12A and the second cabinet opening 12B.
[0048] The double-door refrigerator also includes the door lock structure of the above-mentioned vertical refrigerator. Lock bodies 3 are installed on the left and right sides of the central beam 4. The lock bodies 3 are located in the storage space 11 of the cabinet body 1. The lock hooks 21 installed on the two cabinet doors 2 are all clamped on the lock tongues 31 set on the corresponding lock bodies 3, so that the two cabinet doors 2 respectively close the two cabinet openings 12.
[0049] The middle beam 4 provides an installation position for the two lock bodies 3. While locking the cabinet doors 2 on both sides, it can ensure that the lock bodies 3 are set to the internal storage space 11, realizing the hidden setting of the door locks in the double-door refrigerator structure, thereby improving the safety of the goods in the refrigerator.
[0050] Furthermore, the side of the cabinet door 2 away from the central beam 4 is hinged on the cabinet body 1, and the double-door refrigerator has a split-door structure. Only one lock body 3 is provided for the cabinet door 2 on each side to ensure a secure locking, thereby improving the safety of the goods in the refrigerator and reducing the configuration cost of the door lock.
[0051] Finally, it should be noted that: the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
[0052] The above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the utility model, which should be included in the scope of the technical solution for which protection is requested in the utility model.
