Cooling device

Abstract

Preventing the flow of the ambient air into the cabinet ( 2 ) by closing the discharge pipe ( 4 ) under normal conditions, balancing the cabinet ( 2 ) interior pressure by opening into the cabinet ( 2 ) from the side of the ambient air when the cabinet ( 2 ) interior pressure drops and discharging the water in the cabinet ( 2 ) especially after defrosting, outside of the cabinet ( 2 ) is accomplished by utilizing the valve ( 5 ) which is the object of the present invention.

1 . A cooling device ( 1 ) comprising one or more cooling cabinets ( 2 ) where items to be cooled are stored, a door ( 3 ) serving to close the cooling cabinet ( 2 ) and allowing the user to access the items stored inside the cooling cabinet ( 2 ), a discharge pipe ( 4 ) one end of which extends into the cooling cabinet ( 2 ) and the other end outside the cooling cabinet ( 2 ), and characterized by a valve ( 5 ), having a first flap valve ( 6 ) opening into the discharge pipe ( 4 ), allowing the inflow of ambient air into the cabinet ( 2 ) and a second flap valve ( 7 ) on which the first flap valve ( 6 ) is mounted, moving in the opposite direction of the opening direction of the first flap valve ( 6 ), providing the discharge of fluid in the cabinet ( 2 ) out of the cabinet ( 2 ), opening and/or closing the discharge pipe ( 4 ), allowing the flow of the ambient air into the cooling cabinet ( 2 ) thereby balancing the cabinet ( 2 ) interior pressure and providing the discharge of fluid collected in the cabinet ( 2 ) outside of the cabinet ( 2 ). 
     
     
         2 . A cooling device ( 1 ) as in  claim 1 , characterized by a valve ( 5 ) comprising a first flap valve ( 6 ) and a second flap valve ( 7 ), one inserted into the other. 
     
     
         3 . A cooling device ( 1 ) as in  claim 2 , characterized by a valve ( 5 ) comprising a second flap valve ( 7 ) mounted on the inner wall of the discharge pipe ( 4 ) by a hinge ( 100 ). 
     
     
         4 . A cooling device ( 1 ) as in  claim 2  or  3 , characterized by a valve ( 5 ) comprising a second flap valve ( 7 ) having an opening ( 8 ) on it. 
     
     
         5 . A cooling device ( 1 ) as in  claim 4 , characterized by a valve ( 5 ) comprising a first flap valve ( 6 ) mounted on the second flap valve ( 7 ) by a hinge ( 101 ), opening or closing the opening ( 8 ) on the second flap valve ( 7 ) by moving independently from the second flap valve ( 7 ). 
     
     
         6 . A cooling device ( 1 ) as in any one of the above claims, characterized by a valve ( 5 ) comprising a second flap valve ( 7 ) which opens to the atmosphere as a result of the weight of the water collected over it. 
     
     
         7 . A cooling device ( 1 ) as in any one of the above claims, characterized by a valve ( 5 ) comprising a first flap valve ( 6 ) which opens towards the interior of the cabinet ( 2 ) in the direction of the air inflow formed from the high pressure side to the low pressure side, when the cabinet ( 2 ) interior pressure is lower than the atmospheric pressure. 
     
     
         8 . A cooling device ( 1 ) as in any one of the above claims, characterized by a valve ( 5 ) comprising a stopper ( 9 ) on the inner wall of the discharge pipe ( 4 ), which prevents the second flap valve ( 7 ) mounted on the inner wall of the discharge pipe ( 4 ) moving in a direction from the atmosphere towards the inside of the cabinet ( 2 ). 
     
     
         9 . A cooling device ( 1 ) as in any  claim 1 , characterized by a valve ( 5 ) attached on the discharge pipe ( 4 ) by snap-fitting method. 
     
     
         10 . A cooling device ( 1 ) as in  claim 9 , characterized by a valve ( 5 ) produced as a single-piece. 
     
     
         11 . A cooling device ( 1 ) as in  claim 9  or  10 , characterized by a valve ( 5 ) in which the opening, closing of the first and second flap valves ( 6  and  7 ) is accomplished by changing the thickness of the material on the sections where the first and second flap valves ( 6  and  7 ) are attached, whereby these sections with changed material thickness act as hinges.
