Definitions

the present invention relates to a door opening mechanism enabling opening particularly refrigerator doors.
EP2020579 mentions an actuator enabling opening the doors of refrigerators or freezers.
German patent document no. DE102013223431 mentions an electromagnetic door opening device for opening refrigerator doors.
the documents JP2006046745A , KR20100003347U and JP2003247775A disclose door opening devices for refrigerators.
the document CN1 04328971A discloses an automatic door opening device and refrigerator comprising the same.
the aim of the present invention is to realize a door opening mechanism enabling opening particularly refrigerator doors.
Another aim of the present invention is to realize a door opening mechanism which may be used with current refrigerators.
a further aim of the present invention is to realize a door opening mechanism capable of terminating a door opening process by detecting difficulties likely to occur during opening of a door.
the door opening mechanism (1) enabling opening particularly refrigerator doors, comprises
Said bracket (52) is capable of pressing on the buttons (6) at the points where it is intended to terminate the movement of the gear rack (5).
At least one button (6) is provided capable of contacting the bracket (52) at the position where the gear rack (5) projects the least from the body (2), and at least one button (6) is provided capable of contacting the bracket (52) at the position where the gear rack (5) projects the farthest from the body (2).
the stroke of the gear rack (5) can be increased or decreased by changing the positions of the buttons (6).
the door opening mechanism (1) of the invention can be triggered by a button, a visual or audible command, a proximity sensor and the like.
at least one control unit (not shown in the figures) is provided, receiving said triggers and accordingly enabling driving the driving unit (3).
a sensor capable of detecting a trigger enabling the door to be opened is preferably placed at a region where a user can interact with.
the signal triggering opening of the door can be generated by a button, camera, proximity sensor, RFID reader, or an NFC sensor, placed on the exterior of the refrigerator door.
the above-mentioned triggers are only exemplary and the triggers and the sensors which may be used are not limited to these. A plurality of triggers may also be used.
the door opening mechanism (1) of the invention can conveniently be used with current refrigerators by being placed to the internal chamber of a refrigerator so as to correspond to the door intended to be opened automatically.
