Abstract

A cooling device (1) comprises a door (3) which provides access to an inner volume; a casing (4) which is attached to the cooling device body (2). As the cooling device door (3) gets close to the cooling device body (2) to be closed, a guiding element fixed to the door (3) engages with a movement element of the casing (4). The movement element is pulled by a return spring so that the door (3) is prevented from remaining open and is ensured to be in contact with the cooling device body (2).

Description

    A COOLING DEVICE HAVING A DOOR WITH IMPROVED FUNCTIONALITY
  • The present invention relates to a cooling device wherein the closing performance of the doors thereof after being opened is improved.
  • Cooling device doors comprise shelves on the inner sides. While the cooling device door is opened and closed, the foodstuffs placed into the shelves on the doors may go out of the shelves with the effect of the opening or closing movement. In some cases, after the door is closed, the magnetic gasket on the door may not provide a permanent contact with the body, thus causing the door to remain open. This may cause the cool air kept in the cooling device to leave the unit and get lost, resulting in energy efficiency loss in the product.
  • In the state of the art Patent Application No. WO2011101319, the method for slow closing door by means of a dampening element connected to the door is disclosed.
  • In the state of the art United States Patent Application No. US2010101052, a spring and a dampening element in a joint system are disclosed.
  • In the state of the art German Patent Application No. DE20306043, a system is disclosed wherein the dampening element and the spring operate jointly.
  • Another state of the art document is the United States Patent Application No. US2015240546. In this document, a casing comprising a spring and a dampening element is disclosed.
  • The aim of the present invention is the realization of a cooling device wherein the adverse effects of the closing movement of the door are eliminated.
  • 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 having a connection element and a guiding element at one side thereof; a casing which is attached to the body by means of a fixing apparatus and which is positioned so as to interact with the guiding element on the door; and at least one spring and dampening element which are provided in the casing and which dampen the force.
  • The casing is positioned on the body of the cooling device close to the door. The casing is fixed to the body of the cooling device by means of at least one attaching apparatus. The spring, the movement element and the dampening elements are fixed into the casing.
  • By means of at least one attaching means, the guiding element is fixed onto a side of the door of the cooling device which is close to the body of the cooling device and which aligns with the casing.
  • When the door gets sufficiently close to the body of the cooling device after the door of the cooling device is closed, the guiding element starts to enter an opening provided in the casing. By means of a shape at the end of the guiding element, the guiding element engages with the movement element.
  • The movement element in the casing contacts at least one spring. When the guiding element on the door engages with the movement element, at least one spring in the casing starts to pull the door via the movement element and the guiding element. Thus, the risk of the door remaining open is eliminated.
  • As the door continues to close, a dampening element provided in the casing contacts the door and absorbs the kinetic energy of the door which increase with the pull of the spring and provides that the closing movement slows down and ends with a soft closing.
  • A cooling device realized in order to attain the aim the object of the present invention is illustrated in the attached figures, where:
  • Figure 1 - is the perspective view of a cooling device and a casing.
  • Figure 2 - is the perspective view of the casing.
  • Figure 3 - is the perspective view of the door and the guiding element attached to the door.
  • The elements illustrated in the figures are numbered as follows:
    1. Cooling device
    2. Cooling device body
    3. Cooling device door
    4. Casing
    5. Return spring
    6. Spring retainer
    7. Attaching means
    8. Dampening element
    9. Movement element
    10. Spring housing
    11. Dampening element housing
    12. Guiding element
    13. Guiding element port
    14. Movement channel
  • The cooling device (1) comprises a door (3) which provides access to the inner volume; a casing (4) which is attached to the cooling device body (2); at least one attaching means (7) for fixing the casing (4) to the cooling device body (2); at least one return spring (5) which is disposed into the casing (4); at least one spring retainer (6) which fixes the return spring (5) to the casing (4); a movement element (9) which passes through an opening at the center of the spring retainer (6); a dampening element (8) which is seated into the opening in the casing (4); and a guiding element (12) which is fixed onto the cooling device door (3) by means of the attaching means (7) (Figure 1, Figure 2 and Figure 3).
  • The return spring (5) is positioned into the spring housing (10) by means of the spring retainer (6) in the horizontal plane at the side of the casing (4). The dampening element (8) is placed into the dampening element housing (11). One end of the movement element (9) is fitted into the movement channel (14) and the other end into the spring retainer (6).
  • A guiding element port (13) is provided at the side of the guiding element (12) which is disposed on the cooling device door (3) and which is attached to the cooling device door (3) by means of the attaching means (7). In an embodiment of the present invention, the guiding element port (13) and the movement element (9) are oppositely positioned (Figure 1).
  • The return spring (5) on the casing (4) is fixed to the casing (4) from one end by means of the spring retainer (6). The other end of the return spring (5) engages with the spring retainer (6). The spring retainer (6) is connected to the movement element (9) by means of an opening at the center thereof. With the other end thereof, the movement element (9) is connected to the movement channel (14) which defines the movement path for the movement element (9).
  • In an embodiment of the present invention, as the cooling device door (3) gets close to the cooling device body (2) to be closed, the guiding element (12) engages with the movement element (9) by means of the form of the guiding element port (13). After the engagement is complete, the return spring (5) starts to pull the spring retainer (6) and the spring retainer (6) starts to pull the movement element (9), and the movement element (9) starts to pull the guiding element (12), which is engaged with the movement element (9), along the movement channel (14). Thus, the cooling device door (3) is prevented from remaining open and is ensured to be in contact with the cooling device body (2).
  • In another embodiment of the present invention, the dampening element (8), which is seated into the dampening element housing (11) in the casing (4), dampens the acceleration generated while the cooling device door (3) is being pulled by the return spring (5), thus enabling the door (3) to close softly.
  • In another embodiment of the present invention, the dampening element (8) has a structure which is operated by hydraulic compression method like a piston.
  • In another embodiment of the present invention, the dampening element (8) has a spring-like structure which absorbs the kinetic energy.
