[0023] Reference Figure 1-3 , an embodiment of the present application is proposed, the intelligent unlocking system of the refrigerator described in the embodiment is characterized in that it includes a cabinet 10 with a front opening, the cabinet 10 is divided into a plurality of storage areas 11, each storage area 11 locks a pivot door 30 or a drawer 40 in a closed position through an electronic lock 20, a control module and a password input module 50 are provided on the cabinet 10, and the electronic lock 20 and the password input module 50 are electrically connected to the control module respectively;

[0024] The control module is preset with multiple preset passwords, and each preset password is associated with at least one electronic lock 20. The control module is configured to verify the password input by the password input module 50. If the input password is one of the preset passwords, the electronic lock 20 associated with the preset password is controlled to unlock.

[0025] In the present application, different preset passwords may be used to manage different storage areas 11. For example, the preset password may correspond to one storage area 11, multiple storage areas 11, or all storage areas 11. According to different preset passwords, the partition management of the refrigerator is realized;

[0026] For example, in a refrigerator in a bar, each guest uses one or more storage areas 11 to store wine. When the guest takes the wine by himself, he can open the corresponding storage area 11 with a password to take out the wine by himself.

[0027] Preferably, the cabinet 10 is further provided with a fingerprint collection module 60 electrically connected to the control module, and the control module is configured to control all electronic locks 20 to unlock according to the identity authentication result of the fingerprint collection module 60 .

[0028] The administrator can unlock all electronic locks through the fingerprint collection module 60 for management, which is more convenient to use.

[0029] In this embodiment, the electronic lock 20 is an electromagnetic lock. A rotating door 30 and a drawer 40 are arranged on the front side of the cabinet 10;

[0030] Refer to the attached Figure 3 As shown, when a drawer 40 is provided in the storage area 11, the electronic lock 20 is provided at the inner rear side of the corresponding storage area 11, and a lock groove 22 matching the lock tongue 21 of the electromagnetic lock is provided at the rear side of the drawer 40.

[0031] Refer to the attached Figure 3 As shown, when the storage area 11 is provided with a pivot door 30 at the front side of the cabinet 10 , the electronic lock 20 is provided on the pivot door 30 or the cabinet 10 .

[0032] Preferably, a sensor 70 is provided on the cabinet 10 corresponding to each storage area 11, and the sensor 70 is used to sense the pivot door 30 or drawer 40 of the corresponding storage area 11. When the electronic lock 20 on the cabinet 10 is controlled to be unlocked when a fingerprint or password is input, the lock tongue 21 of the electromagnetic lock retracts to allow the pivot door 30 or drawer 40 to be opened. When all the sensors 70 detect the corresponding pivot door 30 or drawer 40 and the preset time is reached, the control module controls all the electronic locks 20 to lock.

[0033] After the electronic lock 20 on the cabinet 10 is unlocked by inputting a fingerprint or a password, the lock tongue 21 of the electromagnetic lock retracts to allow the hinge door 30 or the drawer 40 to be opened.

[0034] If the hinge door 30 or the drawer 40 is not opened, all sensors 70 can detect the corresponding hinge door 30 or the drawer 40 respectively, and after reaching the preset time, the control module controls all electronic locks 20 to lock so that the lock tongue 21 of the electromagnetic lock can re-extend into the corresponding lock slot 22;

[0035] If any one of the pivot door 30 or the drawer 40 is opened, the sensor 70 corresponding to the opened pivot door 30 or the drawer 40 cannot detect the corresponding pivot door 30 or the drawer 40, and at this time all the electronic locks 20 are inactive. After the user closes the opened pivot door 30 or the drawer 40 after use, all the sensors 70 can detect the corresponding pivot door 30 or the drawer 40 respectively and the preset time is reached, and the control module controls all the electronic locks 20 to lock so that the lock tongue 21 of the electromagnetic lock can re-extend into the corresponding lock slot 22;

[0036] If any one of the pivot door 30 or the drawer 40 is opened, the sensor 70 corresponding to the opened pivot door 30 or drawer 40 cannot detect the corresponding pivot door 30 or drawer 40, and at this time all the electronic locks 20 do not act. After the user has finished using and closes the opened pivot door 30 or drawer 40, all the sensors 70 can respectively detect the corresponding pivot door 30 or drawer 40. The user opens another pivot door 30 or drawer 40 within a preset time, and the sensor 70 corresponding to the opened pivot door 30 or drawer 40 cannot detect the corresponding pivot door 30 or drawer 40. Until the user has finished using and closes the opened pivot door 30 or drawer 40, all the sensors 70 can respectively detect the corresponding pivot door 30 or drawer 40 and the preset time is reached, the control module controls all the electronic locks 20 to lock so that the lock tongue 21 of the electromagnetic lock can re-extend into the corresponding lock slot 22.

[0037] Preferably, the cabinet 10 is also provided with a display 80 electrically connected to the control module, and the display 80 is used to display the unlocked storage area 11, so that the user can open the drawer 40 or the hinge door 30 according to the content displayed on the display 80. In this embodiment, the display 80 and the password input module 50 are integrated on the touch screen.

[0038] Of course, the present invention is not limited to the above-mentioned embodiments, and those skilled in the art may make equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications and substitutions are all included in the scope defined by the claims of this application.
