Description

Technical Field

[0001] The utility model belongs to the technical field of refrigeration and freezing equipment, in particular to a refrigerator. Background Art

[0002] In the modern retail environment, unmanned shopping experience has become increasingly popular. Among them, smart refrigerators, as an innovative way of shopping, provide customers with a more convenient shopping option. These smart refrigerators are remotely controlled through an electronic door lock system, and customers only need to scan the code to open the door and take out the goods. However, despite the significant convenience provided by smart refrigerators, the current system has an important technical flaw, as follows:

[0003] The core components of the smart freezer include an electronic door lock, which is remotely activated by scanning the customer's QR code, so that the door lock is unlocked so that the customer can open the freezer door and take the goods. After the goods are taken, the customer closes the door, and the system should automatically relock the freezer door to protect the safety of the inventory. In addition, in order to improve the customer's shopping experience, the customer scans the code through the mobile phone APP to open the freezer. After the customer takes the goods, the freezer will automatically identify the taken goods and automatically deduct the payment in the customer's mobile phone APP. If the door is not really locked when the customer leaves, the loss of goods thereafter will be deducted from the previous customer's account, which will cause financial losses to the customer. Therefore, the customer needs to confirm whether the door lock is really locked before leaving. However, in the existing system, the door lock lacks an effective monitoring mechanism to confirm whether the door is really locked. Utility Model Content

Thus, a feature defined as "first", "second", and "third" may explicitly or implicitly include one or more of the features.

[0047] 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.

[0048] like Figures 1 to 7As shown, in an illustrative embodiment of the refrigerator of the present invention, the refrigerator comprises a cabinet body 1 , on which a lock body 2 and a cabinet door 3 are mounted.

[0049] The lock body 2 includes a lock core and a lock housing 21. The inner space of the lock housing 21 is divided into a lock core area 2A and a lock hook connection area 2B by a partition block 22, and the lock housing 21 is provided with a lock port 23 connected to the lock hook connection area 2B. The lock core includes a lock tongue 24, which is slidably mounted in a through hole 25 provided in the partition block 22, so that the lock core reciprocates on a straight line between a first lock tongue position and a second lock tongue position.

[0050] The cabinet body 1 has a storage space 11 for accommodating goods. When the cabinet door 3 is closed, the storage space 11 is closed, and the lock hook 31 installed on the cabinet door 3 enters the lock hook connection area 2B through the lock port 23. At this time, if the lock tongue 24 moves to the first lock tongue position, one end of the lock tongue 24 extends into the lock hook connection area 2B, inserts into the insertion groove 32 of the lock hook 31, and engages with the lock hook 31, thereby locking it, so that the cabinet door 3 is locked. When the lock tongue 24 moves to the second lock tongue position, the lock tongue 24 retracts into the lock core area 2A, disconnects from the lock hook 31, eliminates its limit on the lock hook 31, and allows the cabinet door 3 to be opened.

[0051] The lock core area 2A is provided with an identification member 4, which includes an identification plate 41 and a light emitting element 42. The identification plate 41 is installed inside the identification member 4, and the identification plate 41 is located outside the identification member 4 and covers the display window 26 provided in the lock housing 21. The identification member 4 is a transparent plate, and the light emitting element 42 is located on one side of the identification plate 41, so that under the irradiation of the light emitted by the light emitting element 42, the light can pass through the identification plate 41 and be emitted from the display window 26, illuminating the identification plate 41 and making the display window 26 illuminated. The identification member 4 can be a light guide plate, which can emit light as a whole after being irradiated by the light emitting element 42, and form a surface light source with the light emitting element 42. The bright light generated by the surface light source can fill the entire display window 26, making the bright light indication more obvious.

[0052] A photoelectric sensor 5 is installed in the lock core area 2A, and a shielding member 6 is installed on the lock tongue 24. The photoelectric sensor 5 has a transmitting end and a receiving end. The photoelectricity emitted by the transmitting end is received by the receiving end, and the photoelectric sensor 5 generates a light sensing signal. When the shielding member 6 moves between the transmitting end and the receiving end, it is located on the light path and blocks the light. The receiving end cannot receive the light emitted by the transmitting end, thereby cutting off the light sensing signal. When the lock tongue 24 moves to the first lock tongue position, the shielding member 6 is located on the light path of the photoelectric sensor 5 to cut off the light sensing signal of the photoelectric sensor 5; when the lock tongue 24 leaves the first lock tongue position, the shielding member 6 leaves the light path of the photoelectric sensor 5 to restore the light sensing signal. A control circuit board 7 is installed in the lock core area 2A, and the light emitting element 42 and the photoelectric sensor 5 are both electrically connected to the control circuit board 7.

[0053] After the customer closes the cabinet door 3, if the lock tongue 24 moves to the first lock tongue position and locks with the lock hook 31, the cabinet door 3 is locked, the shielding member 6 blocks the light path and cuts off the light sensing signal of the photoelectric sensor 5, and the control circuit board 7 electrically connected to the photoelectric sensor 5 senses the cut-off of the light sensing signal, determines that the lock is successful, and then turns on the power supply to the light-emitting element 42 to make it continuously light up, and the identification plate 41 is illuminated. The customer can see the identification plate 41 is lit through the display window 26, so that the customer knows that the current cabinet door 3 has been locked. If after the customer closes the cabinet door 3, the lock tongue 24 does not move to the first lock tongue position, the cabinet door 3 is not locked, the shielding member 6 is not in the light path of the photoelectric sensor 5, and the light sensing signal is not cut off, the control circuit board 7 senses the existence of the light sensing signal by being electrically connected to the photoelectric sensor 5, determines that the lock is unsuccessful, cuts off the power supply to the light-emitting element 42 to make it in an off state, and the identification plate 41 is not lit, so that the customer can see the identification plate 41 is off through the display window 26, reminding the customer that the current cabinet door 3 is not locked.

[0054] In order to ensure that customers can see whether the identification plate 41 is lit through the display window 26, the lock body 2 can be set on the outside of the cabinet 1, exposing the display window 26 to the outside; or when the lock body 2 is set in the cabinet 1, the cabinet door 3 adopts a display cabinet door 3 with transparent glass, so that the display window 26 on the internal lock body 2 can be seen through the transparent glass.

[0055] In the above-mentioned schematic embodiment, the control circuit board 7 confirms whether the lock tongue 24 is in the first lock tongue position for locking the cabinet door 3 through the photoelectric sensing of the photoelectric sensor 5, thereby correspondingly controlling the light-emitting element 42 to be continuously lit or extinguished, so that the customer can confirm whether the cabinet door 3 is locked by whether the identification plate 41 in the display window 26 is lit, thereby avoiding economic losses to customers due to the loss of goods in the refrigerator that is not locked, and solving the problem that customers of current smart door locks cannot confirm whether the door body is actually locked.

[0056] In order to drive the lock tongue 24, a driving element 8 is installed in the lock core area 2A. The driving element 8 has a valve body 81. The valve body 81 has an electromagnet. An electromagnetic shaft 82 fixedly installed at the inner end of the lock tongue 24 is slidably installed in the valve body, so that the electromagnet drives the electromagnetic shaft 82 to move axially through the action of electromagnetic force, thereby driving the lock tongue 24 to move back and forth in a straight line.

[0057] One side of the lock housing 21 is open so that the components of the lock body 2 such as the lock tongue 24, the partition block 22, and the drive element 8 can be installed therein. The lock housing 21 is closed on its open side by a side plate 27 installed by bolts, thereby encapsulating the components in the lock housing 21.

[0058] A heating wire is installed in the lock housing to heat the lock tongue to prevent it from freezing and ensure smooth expansion and contraction. A sealing ring 13 is installed on the lock tongue to prevent water vapor from entering the lock housing through the gap outside the lock tongue and ensure the stability of the electronic components.

[0059] In some embodiments, a magnet 91 is installed in the lock hook 31, and the magnet can be a magnetic component such as a magnet. A magnetic sensor 92 is installed in the lock core area 2A. The side of the cabinet door 3 away from the lock hook 31 is hinged on the cabinet body 1, so that the lock hook 31 can move on an arc between the first lock hook position and the second lock hook position.

[0060] When the locking tongue 24 moves to the first locking tongue position and the locking hook 31 moves to the first locking hook position, one end of the locking tongue 24 extends into the locking hook connecting area 2B to be locked with the locking hook 31 .

[0061] When the lock hook 31 moves to the first lock hook position, the magnetic sensor 92 and the magnet approach each other to generate a magnetic induction signal; when the lock hook 31 leaves the first lock hook position, the magnetic sensor 92 and the magnet move away from each other to make the magnetic induction signal disappear.

[0062] The control circuit board 7 receives the magnetic induction signal through the magnetic sensor 92, and senses the cut-off of the light induction signal through the photoelectric sensor 5, and determines that the locking is successful, so that the power supply to the light-emitting element 42 is turned on to make it continue to emit light, and the identification plate 41 is illuminated. On the contrary, if the control circuit board 7 does not receive the magnetic induction signal through the magnetic sensor 92, or senses that the light induction signal is not cut off through the photoelectric sensor 5, it is determined that the locking is unsuccessful, and the power supply to the light-emitting element 42 is cut off to make it in an extinguished state, and the identification plate 41 is not illuminated.

[0063] The control circuit board 7 determines whether the magnetic sensor 92 generates a magnetic induction signal to confirm whether the lock hook 31 on the cabinet door 3 enters the lock hook connecting area 2B through the lock port 23. When the lock tongue is extended to the first lock tongue position, the lock hook 31 also reaches the first lock hook position and engages with it, thereby preventing the identification plate 41 from lighting up due to the lock hook 31 not being in place and the lock tongue 24 moving to the first lock tongue position, and further ensuring that the cabinet door 3 is in a locked state when the identification plate 41 is lit.

[0064] When the cabinet door 3 is open, if a self-contained magnet is placed near the magnetic sensor 92, the magnetic sensor 92 will generate a magnetic induction signal, thereby misleading the refrigerator to trigger the driving element 8, making it mistakenly believe that the lock hook 31 has reached the first lock hook position. If the lock tongue 24 is extended to the first lock tongue position at this time, the refrigerator will terminate the settlement of the goods. At this time, the cabinet door 3 is in the open state, and the customer who opened the refrigerator last time will not be charged for taking out the goods, thereby causing the theft and loss of goods.

[0065] In some embodiments, a door body connector 33 is installed on the cabinet door 3, a lock hook is installed on the door body connector 33, an RFID chip 10 is installed on the door body connector 33, and an RFID sensor sheet 20 that generates induction with the RFID chip 10 is electrically connected to the control circuit board 7.

[0066] When the cabinet 1 is opened, the door connecting piece 33 is away from the control circuit board 7, so that the RFID sensor sheet 20 does not sense the RFID chip 10, and the control circuit board 7 controls the driving element 8 to drive the lock tongue 24 to move to the second lock tongue position; when the cabinet door 3 is closed, the lock hook enters the lock hook connection area 2B through the lock port 23, and the door connecting piece 33 is close to the control circuit board 7, so that the RFID sensor sheet 20 senses the RFID chip 10, and the control circuit board 7 controls the driving element 8 to drive the lock tongue 24 to move to the first lock tongue position, locking the cabinet door 3, and at the same time the control circuit board 7 controls the light-emitting element 42 to flash.

[0067] The control circuit board 7 drives the lock tongue 24 to move to the first lock tongue position or the second lock tongue position according to whether the RFID sensor sheet 20 senses the RFID chip 10. Since the RFID chip 10 has a unique identification code, the refrigerator will trigger the driving element 8 to drive the lock tongue 24 to lock the cabinet door 3 only when it senses and authenticates that the cabinet door 3 is closed through the RFID chip 10, so as to more accurately confirm the closing of the cabinet door 3 and prevent the theft of goods.

[0068] In some embodiments, the cabinet body 1 has a storage space 11, and the lock body 2 is located in the storage space 11, so that it is located on the side wall of the cabinet body 1 facing the storage space 11, directly contacting the cold air in the storage space 11, so that when the cabinet door 3 is closed and locked, the lock body 2 is locked inside the refrigerator to prevent it from being exposed to the outside, so that the refrigerator can protect the lock body 2 and prevent the lock body 2 from being considered damaged and causing the theft of goods in the refrigerator.

[0069] However, when the refrigerator is in use, children may easily enter the refrigerator out of curiosity and get locked in. The identification member 4 is slidably installed in the lock core area 2A, and a shifting block 43 is provided on the identification plate 41. The shifting block 43 is slidably installed in the display window 26. The identification member 4 is connected to the lock tongue 24. The child locked in the refrigerator can touch and shift the shifting block 43 through the display window 26, so that the identification member 4 slides and drives the lock tongue 24 to lift and leave the first lock tongue position, thereby eliminating the locking of the lock hook 31, allowing the cabinet door 3 to be opened, realizing the internal unlocking of the refrigerator, and eliminating the safety hazard caused by the child being accidentally locked.

[0070] The display window 26 has a sufficient length so that the shifting block 43 has a sufficient moving distance, so that the lock tongue 24 can be moved from the first lock tongue position to the second lock tongue position under manual operation. In addition, since the shifting block 43 is arranged on the identification plate 41 indicating the closed state of the door lock, when the cabinet door 3 is locked, not only the display window 26 is illuminated to indicate the closed state of the door lock, but also the shifting block 43 can be illuminated to indicate the position of the internal unlocking operating component, so that the child can find the shifting block 43 more quickly and operate it, so as to escape as soon as possible, and further reduce the safety hazard.

[0071] When the shift block 43 slides in the display window 26 , the identification plate 41 always closes the display window 26 to prevent moisture in the refrigerator from entering the lock core area 2A through the display window 26 , thereby preventing the moisture from damaging electronic components such as the control circuit board 7 .

[0072] In some embodiments, the identification member 4 has a horizontally arranged driving plate 44, the driving plate 44 is vertically connected to the identification plate 41, a linkage seat 28 is fixedly mounted on the lock tongue 24, the shielding member 6 is mounted on the linkage seat 28, and the linkage seat 28 is mounted on the upper side of the driving plate 44.

[0073] The identification member 4 falls and remains still on the structure or installed component arranged in the lock core area 2A. When the shift block 43 is manually operated, the pulled-up identification member 4 pushes the linkage seat 28 through the driving plate 44, pulls up the lock tongue 24, and makes it leave the first lock tongue position, thereby eliminating the lock on the cabinet door 3 and realizing manual unlocking of the cabinet door 3.

[0074] When the driving element 8 drives the lock tongue 24 to extend and lock the cabinet door 3, the linkage seat 28 is pressed on the driving plate 44; when the driving element 8 drives the lock tongue 24 to pull up and release the lock of the cabinet door 3, the linkage seat 28 rises accordingly, breaks away from the contact with the driving plate 44, and rises to the space above it. The identification member 4 remains stationary, avoiding the accelerated wear of the identification member 4 due to frequent sliding due to continuous movement with the lock tongue 24, thereby improving the service life of the identification member 4, and also avoiding the degradation of the light guiding performance of the identification member 4 due to wear, thereby ensuring the bright light indication effect.

[0075] In some embodiments, one side of the identification member 4 is slidably mounted on a guide rail 29 provided on the inner wall of the corresponding side of the lock housing 21, and the other side surface is attached to the inner wall of the corresponding side of the lock housing 21. Under the limiting action of the inner wall of one side of the lock housing 21, the identification member 4 is pressed on the guide rail 29 on the other side, and the identification member 4 is limited in a first direction. And due to the cooperation between the identification member 4 and the guide rail 29, the guide rail 29 limits the identification member 4 in a second direction perpendicular to the first direction. The identification member 4 is limited in two vertical directions, so that it is stably installed in the lock housing 21 and can only slide in the direction of the guide rail 29.

[0076] There are guide rails 29 on the inner wall of the lock shell 21 on both sides of the display window 26, and the guide rails 29 are assembled into the slide grooves provided in the identification member 4. The guide rails 29 are located in the slide grooves of the identification member 4, and the two guide rails 29 are respectively located on both sides of the display window 26, so that two sealing structures are formed on both sides of the display window 26, respectively, to prevent water vapor from entering through the gap between the identification member 4 and the inner wall of the lock shell 21, improve the sealing of the lock body 2, prevent water vapor from damaging the lock body 2, make the lock body 2 set inside the storage space 11 work stably, and improve the anti-theft safety of the refrigerator.

[0077] The mating surface 281 provided on one side of the linkage seat 28 is attached to the surface of the corresponding side of the identification member 4, so that the linkage seat 28 is in surface contact with the identification member 4. Since the identification member 4 can only slide in one direction under the limit and cannot rotate, the linkage seat 28 is limited in the rotation direction through surface contact, so that it cannot rotate with the lock tongue 24 as the axis, thereby avoiding the linkage seat 28 from moving away from the top of the drive plate 44 due to rotation, ensuring the overlap of the linkage seat 28 and the drive plate 44, and ensuring that the identification member 4 can manually drive the lock tongue 24 through the linkage seat 28.

[0078] In some embodiments, a support plate 45 is installed between the identification plate 41 and the driving plate 44, and the support plate 45 is vertically connected to both the identification plate 41 and the driving plate 44. The support plate 45 serves as a stiffening rib to reinforce the identification plate 41, thereby preventing the identification plate 41 from being deformed inwardly when the shift block 43 is manually operated due to its low strength, so that the identification plate 41 maintains sliding contact with the inner wall of the lock housing 21, continuously closes the display window 26, and maintains a barrier effect against water vapor.

[0079] In some embodiments, there are two support plates 45 , one support plate 45 is attached to the inner wall of the lock housing 21 , and the other support plate 45 is attached to the mating surface 281 of the linkage seat 28 .

[0080] Through the two support plates 45, the identification member 4 is not only limited by the guide rail 29 in the second direction, but also the inner wall of the lock shell 21 and the linkage seat 28 connected to the lock tongue 24 limit it in the second direction on both sides, thereby improving its stability in the second direction and allowing it to slide smoothly under the guidance of the guide rail 29 without moving in the second direction.

[0081] In some embodiments, the linkage rod 282 provided on the linkage seat 28 extends above the driving plate 44 and contacts its upper surface, and the linkage rod 282 is slidably installed in the guide groove 46 provided on the support plate 45 on the corresponding side.

[0082] The linkage seat 28 is overlapped with the driving plate 44 through the linkage rod 282. The guide groove 46 eliminates the blocking of the linkage rod 282 by the support plate 45, so that it extends to the top of the driving plate 44 and overlaps with it, and by guiding the linkage rod 282, the movement of the lock tongue 24 is smoother when it retracts and contracts. In addition, the linkage rod 282 is inserted into the guide groove 46, so that it can limit the linkage seat 28 in the rotation direction.

[0083] The linkage rod 282 is attached to the inner wall of the guide groove 46, so that the identification plate 41 is pressed against the inner wall of the lock housing 21 on the corresponding side, stably closing the display window 26. Since the linkage seat 28 is in surface contact with the identification member 4 through the matching surface 281 and cannot rotate, the linkage rod 282 maintains a fixed angular position in the circumferential direction, and the linkage rod 282 can support the identification member 4 through the inner wall of the guide groove 46, thereby improving the stability of the identification member 4 in the first direction.

[0084] In some embodiments, one side of the lock shell 21 is open and closed by an installed side panel 27. The cross-section of the side panel 27 is L-shaped, and is divided into a covering portion 271 and an assembly portion 272. The covering portion 271 is located on the side of the lock shell 21 away from the display window 26. The assembly portion 272 extends into the lock shell 21 and is attached to the inner wall of the lock shell 21. One end of the assembly portion 272 presses the identification member 4 on the inner wall of the lock shell 21 close to the display window 26. A rib 12 is vertically provided on the inner wall of the lock shell 21. The rib 12 is located on the side of the display window 26 away from the assembly portion 272. The identification member 4 is vertically connected with a baffle 47, and the baffle 47 is attached to the baffle 12. The two guide rails 29 are located between the assembly portion 272 and the baffle 12.

[0085] One side of the lock case 21 is open, and the cross section is U-shaped, so that the lock tongue 24, the identification member 4, the driving element 8 and other components can be easily installed into the lock case 21. The lock case 21 is closed by an L-shaped side plate 27, a part of which extends into the lock case 21 and contacts with its inner wall surface, and has a wider contact surface, so as to better seal the lock case 21, and the extended part presses the identification member 4, so that the identification member 4 more tightly closes the display window 26, and at the same time, a retaining edge 12 is provided on the other side of the display window 26 and a baffle 47 is also provided on the other side of the identification member 4, and the baffle 47 contacts with the retaining edge 12 to form another sealing structure, thereby improving the sealing performance of the connection between the identification member 4 and the lock case 21 and preventing water vapor from entering due to the opening of the display window 26.

[0086] 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.
