Definitions

• the present invention relates to a cooling device that comprises drawers.
• the cooling devices comprising drawers are devices wherein a cooling or freezing volume is separated by drawers placed on top of one another without a wall therebetween.
• the cooling device does not have a separate door wherein the cover of each drawer forms the cooling device door. Access to inside of the cooling device is maintained by pulling the drawer outward, loading and unloading therein can be performed when the drawer is pulled out.
• Gaskets that surround the cover are provided behind each drawer cover.
• a beam or beams are provided between the drawers, whereto these gaskets bear against, insulating the cooling volume from the outside.
• the gasket bears against the frame and the beam and leak-proofing is maintained.
• This beam connects the two side walls at the front of the body.
• the said beam does not separate the cooling volume into two, only forming a surface whereto the gaskets bear against when the drawers are closed for providing insulation of the cooling volume.
• a cooling volume for example two drawers can exist in the same cooling conditions.
• the said beam (K) is stationary.
• the drawers (A) are produced with less depth so that the drawers (A) can be pulled outward from above and under the beam (K) without colliding since the beam (K) is stationary and a dead zone (D) is formed between the two drawers (A) in the portion corresponding to the beam (K). This zone cannot be utilized by the user and causes the energy consumption values of the cooling device to increase ( Figure 1).
• the beam is secured on the upper drawer and the weight of the drawer is increased. Moreover, when the upper drawer is opened, the leak-proofing of the lower drawer fails since there isn't any surface whereon the gasket of the closed lower drawer can contact with since the beam moves together with the drawer.
• the aim of the present invention is the realization of a cooling device wherein the usage volume of the drawers is increased.
• 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 more than one drawer, disposed one over the other in the cooling or freezing volume, moving in the horizontal direction and a beam that moves away from the path the drawer follows by the actuation of the opened drawer, rotating about its axis and being shifted.
• the cooling device furthermore comprises a housing, above or below the drawer, just behind the cover, extending along the front side of the drawer and wide enough for the rotating inside and shifting beam to be seated therein.
• the beam stands upright between the drawers. In this position, when the drawers are closed, both of the gaskets of the two drawers simultaneously press on a bearing surface on the beam and leak-proofing is maintained between the drawers and the outside environment.
• the beam changes to the horizontal position by rotating and shifting and settles in the housing of the closed drawer.
• only the gasket of the closed drawer presses on the other narrower bearing surface, situated oppositely on both sides of the rotational axis and extending vertically to the bearing surface.
• the other closed drawer presses on thereby minimizing the effect on the leak-proofing.
• the cooling device furthermore comprises two guides, that direct the motion of the beam, the arms thereof preferably facing inside the body, configured as a canted "U" shape and two pins situated at both ends of the beam, forming the rotational axis, moving inside the guides and between the arms depending on the motion of the drawers.
• the cooling device comprises springs inside the guide that maintain the beam to return to the former position wherein the gaskets of both drawers can press on when the drawers are closed, with one ends secured to both arms of the guide such that the pin remains therebetween and the other ends secured on both sides of the pin.
• the distance between the drawers can be reduced such that both drawers are allowed to move without brushing against each other. This permits the use of deeper drawers. Moreover, when one of the drawers is opened, the other closed drawer is affected from the outside environment minimally. This lowers the energy consumption of the cooling device to a minimum.
• Figure 1 - is the schematic view of a cooling device in the prior art.
• Figure 2 - is the schematic view of a cooling device when the drawers are inside the body.
• Figure 3 - is the schematic view of the cooling device while the upper drawer is pulled out of the body.
• Figure 4 - is the schematic view of the cooling device while the lower drawer is pulled out of the body.
• Figure 5 - is the schematic view of the path followed by the beam while the lower drawer is pulled out of the body.
• Figure 6 - is the schematic view of the beam, housing, pin and the springs when the drawers are closed, when the upper drawer is open and when the lower drawer is open.
• the cooling device (1) comprises a body (2), at least two drawers (3) disposed one over the other inside the body (2), moving in the horizontal direction, a cover (4) allowing the drawer (3) to be pulled out of the body (2) for accessing inside, and one or more gaskets (9) mounted on the rear surface of the cover (4) and surrounding the cover (4).
• the cooling device (1) comprises a beam (5)
• the cooling device (1) furthermore comprises a housing (10) above or under the drawer (3), just behind the cover (4), extending along the portion corresponding to the front side of the drawer (3), wherein the beam (5) can be seated.
• the beam (5) seated in the housing (10) on the other drawer (3), does not hinder the movement of the other drawer (3) and provides the said drawer (3) to move in the horizontal direction outwards from the cooling device (1).
• the beam (5) comprises at least a first bearing surface (S1) whereon the gaskets (9) on both covers (4) bear against when the drawers (3) are in the closed position inside the body (2) and at least two second bearing surfaces (S2), vertical to the said first bearing surface (S1), situated oppositely on both sides of the fastening axis to the body (2), and narrower than the first bearing surface (S1), whereon only the gasket (9) on the cover (4) of the drawer (3) in the closed position presses on when one of the drawers (3) is opened.
• S1 first bearing surface
• S2 vertical to the said first bearing surface (S1), situated oppositely on both sides of the fastening axis to the body (2), and narrower than the first bearing surface (S1), whereon only the gasket (9) on the cover (4) of the drawer (3) in the closed position presses on when one of the drawers (3) is opened.
• the bearing surface (S1) whereto the gaskets (9) contact can be changed when both of the drawers (3) are inside the body (2) and when either one is opened.
• the first bearing surface (S1) is used, that is wide enough for the gaskets (9) on both drawers (3) to bear against, and when one of the drawers (3) is brought to the open position, the narrower second bearing surface (S2) is used whereon only the gasket (9) on the drawer (3) in the closed position can contact.
• the cooling device (1) furthermore comprises two guides (7), disposed oppositely on both side walls of the body (2), with one arm placed to be corresponding under the upper drawer (3), and the other arm above the lower drawer (3), having a curvilinear orbit between these two arms, the arms configured as a canted "U" shape facing inside the body (2) and two pins (6) situated at both ends of the beam (5), forming the rotational axis of the beam (5), by being seated inside the guides (7) and moving between the arms of the guide (7) depending on the motion of the drawers (3).
• the pin (6) maintains the beam (5) to rotate around its axis in the guide (7) on the body (2) side wall.
• the beam (5) moves upward in the vertical plane and toward inside the body (2) in the horizontal plane, and is seated in the housing (10) on the upper drawer (3), without hindering the motion of the lower drawer (3).
• the beam (5) moves downward in the vertical plane and pulled inside the body (2) in the horizontal plane, being seated in the housing (10) on the lower drawer (3), without hindering the motion of the upper drawer (3).
• the cooling device (1) furthermore comprises two springs (8) in each guide (7), with one ends secured on both sides of the pin (6) such that the pin (6) remains therebetween and the other ends secured to both arms of the guide (7) thereby maintaining the beam (5) to return to the former position when the drawer (3) is placed in the body (2) ( Figure 6).
