  • The cooling device (1) comprises one or more than one compartment (2) wherein foods and beverages are placed and that has an inlet port (3) enabling the user to access therein, two side walls (4) and a rear wall (5); an evaporator (6) that is disposed onto the rear wall (5) and wherein the refrigerant fluid is circulated; a fan (7) that is disposed on the evaporator (6t) and that delivers the cold air into the compartment (2); a cover (8) that is disposed into the compartment (2) and that is disposed onto the rear wall (5) so that the evaporator (6) remains between the cover (8) and the rear wall (5),
    • a box (9) wherein the fan (7) is disposed, that is defined by more than one wall (10) and a base (11) that extend from over the cover (8) into the compartment (2),
    • a fan cover (12) that is fixed onto the base (11),
    • one or more than one window (13) that is disposed on the walls (10), and
    • one or more than one illumination element (13) that is disposed behind the windows (13) between the box (9) and the rear wall (5).
  • (Figure 1 and Figure 2).
  • When the illumination elements (15) are activated automatically or by the user, the light dispersing in the box (9) passes through the windows (13) on the walls (10) of the box (9) so as to disperse in the compartment (2). The user viewing the interior of the compartment (2) perceives that the light disperses from the sides of the fan cover (12). Thus, the upper part of the compartment (2) is effectively illuminated and a nice and esthetic outer appearance is obtained.
  • In an embodiment of the present invention, the illumination element (15) is a LED.
  • In another embodiment of the present invention, the walls (10) extend into the compartment (2) almost perpendicularly to the plane of the cover (8), and the windows (13) are positioned on the walls (10) so as to face the side walls (4) and the base of the compartment (2). Thus, almost all of the light emitted by the illumination element (15) leaves through the windows (13) to disperse in the compartment (2).
  • In another embodiment of the present invention, the cooling device (1) comprises one or more than one plate (14) that covers the windows (13) and that has a light transmittance property whether transparent or semitransparent. In a version of this embodiment of the present invention, the windows (13) has a structure, preferably in the form of a U, that extends along the walls (10) of the box (9). Accordingly, the plate (14) is fixed onto the window (13) and has the same form as the window (13) so as to completely cover the window (13). In this embodiment, the fan (7) is disposed between the windows (13). In the preferred embodiment, the plate (14) is produced from PMMA material. When the illumination element (15) is activated, the light dispersing in the box (9) passes through the plate (14) by diffracting and disperses in the compartment (2) (Figure 8).
  • The cooling device (1) comprises one or more than one hole (17) that is disposed almost at the center of the base (11) and that enables the air moved by the fan (7) to be delivered into the compartment (2); a fan cover (12) that prevents access to the holes (17) from the outside, that enables the air leaving through the holes (17) to disperse into the compartment (2), and an opening (18) that is arranged between the base (11) and the fan cover (12). The fan cover (12) is mounted onto the base (11) so as to allow the air moved by the fan (7) in the box (9) to leave through the holes (17) and so that the opening (18) remains between the fan cover (12) and the base (11). The fan cover (12) almost completely covers the base (11) so as to prevent the holes (17) on the base (11) to be seen across from the fan cover (12). The air moved by the fan (7) leaves the box (9) through the holes (17) on the base (11) and hits the rear surface of the fan cover (12) facing the base (11) so as to pass through the opening (18) between the base (11) and the fan cover (12) and reach the interior of the compartment (2). In this embodiment of the present invention, the base (11) and the fan cover (12) are rectangular. By means of the fan cover (12) fixed onto the base (11) so that the opening (18) remains therebetween, the air is enabled to be homogeneously dispersed into the compartment (2) (Figure 3 and Figure 4).
  • In another embodiment of the present invention, the cooling device (1) comprises one or more than one support (16) that is disposed into the box (9) and whereon the illumination elements (15) are fixed. In the preferred embodiment of the present invention, the support (16) is shaped as a U profile. The cooling device (1) comprises at least one slide-rail mechanism (22) oppositely disposed on the support (16) and the box (9), that enables the support (16) to be fixed to the box (9). By means of the support (16), the illumination elements (15) are together mounted to or dismounted from the cooling device (1) instead of being mounted one at a time (Figure 8).
  • The cooling device (1) comprises at least one protrusion (21) that is disposed on the surface of the fan cover (12) facing the cover (8) and at least one recess (20) that is arranged on the base (11) and that receives the protrusions (21), wherein the protrusion (21) and the recess (20) enable the fan cover (12) to be fixed onto the fan (11). The cooling device (1) furthermore comprises at least one foot (19) that enables the opening (18) to remain between the fan cover (12) and the base (11) and that enables the fan cover (12) to be fixed onto the base (11) so that the opening (18) remains therebetween. The foot (19) extends between the fan cover (12) and the base (11), and when the foot (19) on the fan cover (12) bears against the base (11), the protrusion (21) engages with the recess (20), thus completing the fixing process. Thereby, the fan cover (12) is enabled to be fixed onto the base (11) so that an opening (18) as much as the length of the foot (19) remains therebetween. Moreover, the foot (19) increases the strength of the fan cover (12) when a force is applied on the fan cover (12) (Figure 5 and Figure 6).
  • In another embodiment of the present invention, the cover (18) and the plate (14) are assembled as described below: The plate (14) is placed into the injection mold before the cover (8) is injected into the injection mold. Then, the melt material of the cover (8) is placed into the mold. Thus, the cover (8) is produced as a single piece with the plate (14) thereon when the molding process is completed.
