Definitions

  • the present invention relates to a cooling device comprising a door closing mechanism and the control method thereof.
  • the door being left open adversely affects the cooling efficiency. Therefore, it is important for the cooling efficiency of the cooling devices to enable the door to be properly closed. It is very difficult for users to close the door especially when their hands are full. Since the user can close the door only by pushing the same, the door may close at different speeds. When the said pushing force is less or more, the door may not close properly. Therefore, although the user thinks the door is closed, the door may remain ajar. This situation causes excessive energy consumption and the spoiling of the stored foodstuffs.
  • a cooling device comprising doors that are opened or closed by means of bevel gears disposed on the body.
  • the aim of the present invention is the realization of a cooling device wherein the door remaining open is enabled to be automatically closed.
  • the cooling device realized in order to attain the aim of the present invention, explicated in the first claim and the respective claims thereof, comprises a door closing mechanism having two bevel gears that are disposed on the body and the door and that enable the door remaining open to be automatically closed.
  • the two bevel gears directly contact each other on the door and are moved by a motor operated according to the remaining open time of the door, thus enabling the door to move with respect to the body and close on the body.
  • the door is prevented from remaining open.
  • the door closing mechanism comprises a cover that protects the motor fixed onto the body and a casing that protects the second shaft fixed onto the body and the first gear and the second gear contacting each other on the door. While a cavity through which the first shaft passes is arranged on the cover, an L-shaped housing through which the first shaft passes and that enables the casing to move with respect to the first shaft is arranged on the casing. The said housing is arranged on the adjacent walls of the casing that remain parallel to the frame of the body when the door is open and closed. By means of the L-shaped housing, the first shaft extending from the body towards the door is prevented from blocking the movement of the door.
  • the cooling device is controlled according to the remaining open time of the door and the motor is operated according to the remaining open time of the door.
  • it is detected that the door cannot be closed due to an object between the door and the body, and thus the motor is stopped.
  • the door is automatically closed.

  • the cooling device (1) comprises one or more than body (2) wherein the objects to be cooled are placed and that have an inlet port (A) enabling the user to access therein; one or more than door (3) that prevents the heat transfer between the body (2) and the outer environment when closed, that enables the user to access the interior of the body (2) when opened and that is mounted to one side of the body (2); at least one hinge (18) that enables the door (3) to open/close and to rotate around the edge whereat the door (3) is mounted to the body (2); a sensor (16) that detects if the door (3) is open, and a control unit (17).
  • the cooling device (1) of the present invention comprises a door closing mechanism (4) having
  • the first gear (6) and the second gear (8) constantly contact each other independently from the position of the door (3).
  • the sensor (16) detects that the door (3) is left open and delivers this information to the control unit (17).
  • the control unit (17) operates the motor (9).
  • the motor (9) When the motor (9) is operated, the first shaft (5) with one end being connected to the motor (9) starts to rotate around its own axis and rotates the first gear (6) that is fixed to the other end thereof.
  • the second gear (8) contacting the first gear (6) starts move and the door (3) together with the second shaft (7) fixed onto the door (3) moves over the hinge (18) whereby the door (3) is mounted to the body (2).
  • the door (3) As the first gear (6) rotates the second gear (8), the door (3) also moves with respect to the door (2) and closes over the body (2). Thus, when the door (3) of the cooling device (1) is left open or cannot be closed properly, the door (3) is enabled to be completely closed by means of the door closing mechanism (4).
  • the first shaft (5) extends in the horizontal direction and the second shaft (7) in the vertical direction.
  • the door closing mechanism (4) comprises the motor (9) that is fixed onto the ceiling of the body (2) at the edge thereof close to the door (3), a cover (10) that partially encloses the first shaft (5), a cavity (12) on the cover (10), through which the first shaft (5) passes, and fixing members (15) that enable the cover (10) to be fixed onto the body (2).
  • the fixing members (15) on the cover (10) engage with the recesses on the body (2) and enable the cover (10) to be fixed onto the body (2) ( Figure 2, Figure 3 and Figure 4).
  • the door closing mechanism (4) furthermore comprises a connection member (14) that is fixed onto the upper surface of the door (3) and that has the first shaft (7) on its end, extending in the vertical direction and a casing (11) that covers the connection member (14), the first gear (6) and the second gear (8).
  • the connection member (14) carrying all the load has a stepped configuration for the reinforcement thereof.
  • the casing (11) comprises an L-shaped housing (13) through which the first shaft (5) and that extends along two adjacent edges - which are the edges parallel to the frame on the body (2) when the door (3) is completely open or closed - in the horizontal direction.
  • the first shaft (5) whereto the first gear (6) is mounted passes through the cavity (12) on the cover (10) and through the housing (13) on the casing (11) so as to extend from the body (2) towards the door (3) and the first gear (6) on the first shaft (5) contacts on the door (3) the second gear (8) mounted onto the second shaft (7) extending in the vertical direction on the door (3).
  • the first and the second gears (6, 8) are enclosed by the casing (11).
  • the senor (16) is a reed switch that is mounted onto the body (2) and that is activated by magnetic field, and a magnet (19) that is mounted onto the door (3).
  • the magnet (10) triggers the reed switch and the information that the door (3) is closed is delivered to the control unit (17). Since the magnet (19) does not trigger the sensor (16) when the door (3) is open, the reed switch shifts to the active position and the information that the door (3) is open is delivered to the control unit (17).
  • control method executed by the control unit (17) for the control of the cooling device (1) of the present invention comprises the following steps:
  • the motor (9) is operated for a predetermined time (T3) (700). If the door (3) is not closed at the end of this time (T3) (800), it is decided that an obstruct is present between the door (3) and the body (2) and the motor (9) is stopped (900) ( Figure 11).
  • the door (3) in case the door (3) is left open or not properly close, the door (3) is enabled to be automatically closed. Thus, unfavorable situations that may occur due to the door (3) remaining open are prevented.
