  • the plate (9) is assembled on the movement mechanism (8) in the compartment (2) so that there is some gap between itself and the walls of the compartment (2) such that there is minimum contact. Accordingly, the effect of the factional forces affecting the motion adversely during movement is minimized.
  • the cooling device (1) comprises one or more housings (14) on the compartment
  • the opening closing mechanism (7) has the dimensions and shape to completely close the opening (6) in the closed position, that is when there are no items on the plate (9), and to completely open the opening (6) in the open position, that is when the weight emplaced on the plate (9) is greater or equal to the force applied by the movement mechanism (8) on the plate (9).
  • the opening closing mechanism (7) can be a part of the plate (9) or it can be a separate part that is assembled to the plate (9).
  • the plate (9) moves by the weight of the items on it, it is in a balanced position when there are no items on it.
  • the only force applied on the plate (9) is the force applied by the movement mechanism (8) on the plate (9) and this force is in balance with the weight of the plate (9) and the plate (9) is at the farthest point from the compartment (2) base.
  • the opening closing mechanism (7) completely closes the opening (6) that provides the air to be blown from the air channel (5) to the plate (9). Accordingly, since there are no items on the plate (9) to be cooled, air is not blown from this opening (6).
  • the opening closing mechanism (7) may be completely or partially open at the position of balance.
  • the plate (9) is at the closest position to the compartment (2) base.
  • This position where the opening closing mechanism (7) does not form any obstructions on the opening (6) for the air to flow, is preferably the completely open position. Accordingly, in this position when the need for cooling is the greatest, the opening (6) completely opens to provide the air in the air channel (5) to be blown into the compartment (2) from this opening (6).
  • the opening closing mechanism (7) partially covers the opening (6) and provides a lesser amount of air to be blown into the compartment (2) from the opening (6) as compared to the position of the opening closing mechanism (7) when it is completely open.
  • the plate (9) starts to move away from the base of the compartment (2) in the reverse direction of gravity. It stops automatically at the position of balance when balance is maintained.
  • the opening closing mechanism (7) partially or completely covers the opening (6) depending on the weight of the items on the plate (9).

  • the opening closing mechanism (7) comprises an assembly hole (12) that provides for its assembly on the plate (9), a hinge (10) that fixes it to the air channel (5) such that it can swing in the air channel (5) and a spring (11) positioned on the hinge (10) that applies force against the swing of the opening closing mechanism (7) and when the force applied on the opening closing mechanism (7) is lifted, providing the opening closing mechanism (7) to resume its former position.
  • the plate (9) comprises a hanger (13) that extends through the opening (6) into the air channel (5) and being attached to the assembly hole (12) on the opening closing mechanism (7) providing the attachment of the plate (9) with the opening closing mechanism (7).
  • the plate (9) and the opening closing mechanism (7) are removably hung on each other.
  • the plate (9) is provided to be taken out of the compartment (2) for the purpose of cleaning or filling in.
  • the opening closing mechanism (7) is fixed to the air channel
  • the opening closing mechanism (7) by means of the hinge (10) and the opening closing mechanism (7) is attached to the plate (9) by assembling the hanger (13) in the assembly hole (12), providing the movement of the plate (9) to be transferred to the opening closing mechanism (7). Accordingly, when force is applied on the opening closing mechanism (7), the opening closing mechanism (7) moves in the direction of the applied force and starts rotating around the hinge (10). The opening closing mechanism (7) moving away from the opening (6) and approaching into the air channel (5) provides the opening (6) to be opened and the air flow in the air channel (5) to be delivered into the compartment (2).
