Definitions

  • the present invention relates to a door opening mechanism enabling opening particularly refrigerator doors.
  • “Hands-free” refrigerators having automatic door opening mechanisms enabling users to access into a refrigerator without using hands, are known and used in the art.
  • automatic refrigerator door opening mechanisms the force applied on a door should exceed the vacuum effect also acting on the door in order to open the door automatically.
  • a door may damage a user and/or the items in its proximity by colliding. Therefore, automatic door opening mechanisms are needed which do not inflict damage on a user while performing smoothly the door opening function.
  • automatic door opening mechanisms are expected to perform the door opening function independent of door weights varying due to the products placed thereon.
  • 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 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.
  • Figure 1 is a schematic view of an embodiment of the invention.
  • Figure 2 is a view of an embodiment in which the sensor is connected to the slide.
  • Figure 3 is a view of an embodiment in which the sensor is connected to the plate coupled to the drive unit.
  • Figure 4 is a view of an embodiment in which the sensor is connected to the plate coupled to the reducer.
  • the door opening mechanism (1) enabling opening particularly refrigerator doors, comprises
  • the door opening mechanism (1) enabling opening particularly refrigerator doors, comprises in its most basic form, at least one body (2) and a driving unit (3) connected to said body (2).
  • the driving unit (3) may be any structure generating actuation by rotating a shaft, such as an electric engine.
  • the rotational motion generated by the driving unit (3) is then transmitted to the reducer (4).
  • the reducer (4) reduces the speed of the rotational motion, thereby increasing the torque thereof.
  • the reducer (4) transmits said motion to the gear rack (5).
  • the gear rack (5) moves linearly due to the force applied by the reducer (4).
  • the gear rack (5) moves so as to apply a force on the door intended to be opened at the position where the movement mechanism (1) is placed.
  • the gear rack (5) has at least one bracket (52).
  • Said bracket (52) is capable of pressing on the button (6) preferably 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 is placed such that the gear rack (5) can apply a force on the door in door opening direction.
  • the door opening mechanism (1) of the invention can be placed to the internal volume of a refrigerator.
  • the force that the gear rack (5) should apply on a refrigerator door when it is desired to open the refrigerator door depends on a number of factors. For example, the air with room temperature introduced when the refrigerator door is opened and closed, encounters a cold environment in the refrigerator and its temperature and therefore its volume decreases. The decreased volume creates a negative pressure (vacuum) in the refrigerator. Furthermore, the loading state of the refrigerator door also affects the opening force. Since the gear rack (5) should generate a force to overcome all of these forces, the torque of the motion received from the driving unit (3) is increased by the reducer (4).
  • 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.
  • a structure is provided detecting that the driving unit (3) is hampered due to applying a resistance against the door intended to be opened, a jamming of the door for any reason whatsoever, and not being able to open the door.
  • This structure comprises at least one sensor (7).
  • the structure detecting that the driving unit (3) is hampered preferably comprises at least one slide (51) connected to the gear rack (5) and at least one sensor (7) enabling detecting whether said slide (51) is moving.
  • the slide (51) preferably has lower and higher portions like a battlement on a bastion.
  • the sensor (7) is preferably an optocoupler comprising at least one light source and at least one light detector. At least a portion of the slide (51) can pass in between the light detector and the light source. When the higher portion of the slide (51) enters in between the light detector and the light source, the light beams emitted from the light source cannot reach the light detector. In this case, let us assume that the outlet of the sensor (7) is boolean 0.
  • the outlet of the sensor (7) When the lower portion of the slide (51) enters in between the light detector and the light source, the light beams emitted from the light source can reach the light detector. In this case, the outlet of the sensor (7) would be boolean 1.
  • the sensor (7) can also be configured to assign boolean 1 when the light beams cannot reach the light detector, and boolean 0 when the light beams can reach the light detector.
  • the slide (51) comprises a plurality of lower and higher portions preferably placed consecutively. Thus, when the slide (51) is moving within the sensor (7), the outlet of the sensor (7) continuously switches between boolean 0 and 1 values. When the outlet of the sensor (7) is constant, this implies that the slide (51) and therefore the gear rack (5) is not moving.
  • the structure detecting that the driving unit (3) is hampered preferably comprises at least one plate (8) engageable to the shaft of the driving unit (3) or to any gear of the reducer (4), and rotating together with the component it has engaged.
  • the movement mechanism (1) of the invention comprises at least one sensor (7) enabling detecting whether the plate (8) is moving.
  • the plate (8) preferably has leaves like a daisy.
  • the sensor (7) is preferably an optocoupler comprising at least one light source and at least one light detector. At least a portion of the plate (8) can pass in between the light detector and the light source.
  • the outlet of the sensor (7) is boolean 0.
  • the portion of the plate (8) between the leaves enters in between the light detector and the light source, the light beams emitted from the light source can reach the light detector.
  • the outlet of the sensor (7) would be boolean 1.
  • the sensor (7) can also be configured to assign boolean 1 when the light beams cannot reach the light detector, and boolean 0 when the light beams can reach the light detector.
  • the plate (8) comprises a plurality of leaves preferably placed consecutively, and there are gaps in between consecutive leaves.
  • the movement mechanism (1) of the invention comprises at least one control unit (not shown in the figures) adapted to execute at least one of the operations including: driving the driving unit (3) directly or by means of an interface circuit, detecting the state of the button (6), receiving data from the sensor (7), determining according to said data received from the sensor (7) whether there is resistance against a door intended to be opened, and upon determining presence of a resistance, halting driving of the driving unit (3) or driving the driving unit (3) in an opposite direction to bring the door to its initial position.
  • the control unit determines that the door has encountered a resistance when the sensor (7) output is constant although the driving unit (3) is being driven. In this case, the control unit can halt driving the driving unit (3) or can bring the gear rack (5) to its initial position by driving the driving unit (3) in the opposite direction.
  • control unit can halt driving the driving unit (3) or can bring the gear rack (5) to its initial position by driving the driving unit (3) in the opposite direction also when it determines that the slide (51) of the gear rack or the plate (8) is moving in a speed slower than a predetermined speed although the driving unit (3) is being driven.
  • 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.
