Definitions

  • the present invention relates to a cooling device comprising a valve which provides the balancing of the pressure imbalanced during opening, closing of the door and discharging the water created especially during the defrost process.
  • Cooling device of the current state-of-the-art comprises a cooling cabinet and a door which is attached to the cooling cabinet, to be opened or closed by the help of a hinge, providing access to the cooling cabinet.
  • the cooling cabinet is insulated from the outer surroundings in a leak-proof manner when the door is closed. Frosting occurs around the evaporator during the cooling process. This frost is melted by various defrost methods, the melted water is discharged with the help of a drain pipe, one end of which opens into the cooling cabinet and the other to the outside of the cabinet, that is to the ambient atmosphere.
  • the water discharged to outside of the cabinet is transferred to a collector unit situated preferably in the section of the cooling device where the compressor cabinet is positioned.
  • the discharge pipe discharging the water collected in the cooling cabinet is the only exit passage of the cabinet to the atmosphere.
  • a vacuum is formed inside the cabinet due to the opening and closing of the door or other causes, air is sucked into the cabinet from the end of the discharge pipe opening to the ambient atmosphere. If the amount of water in the discharge pipe or in the collecting unit where the end of the discharge pipe opens is more than enough, water and air is sucked into the cabinet until the cabinet pressure is in equilibrium with the atmospheric pressure.
  • the noise generated by the air and water mixture flowing through the discharge pipe can reach a level that is annoying to the user.
  • the discharge pipe being the only place that is open to the ambient atmosphere while the door of the cabinet is closed, will also result in temperature and pressure abnormalities in the cooling cabinet, in addition to all the above explained adversities.
  • the discharge pipe is made in a “U” shape so that some amount of water stays in the pipe—especially water from the defrost process—preventing the air which is comparably warmer than the cooling cabinet medium to flow into the cooling cabinet from the end of the discharge pipe that is open to atmospheric pressure, disrupting the temperature and pressure balance of the cabinet.
  • the entrapping of water in the “U” shaped discharge pipe prevents the flow of air into and out of the cabinet. Since the flow of air from the ambient atmosphere into the cabinet to eradicate the pressure imbalance is blocked by the water entrapped in the discharge pipe, as a result the pressure imbalance in the cabinet can not be adjusted and opening the cooling device door requires the exertion of a larger force.
  • the object of the present invention is to design a cooling device comprising a valve which prevents the temperature and pressure abnormalities inside the cooling cabinet and also provides the discharging of especially the defrost water.
  • FIG. 1 is the schematic view of a cooling device.
  • FIG. 2 is the schematic top view of a valve.
  • FIG. 3 is the schematic top view of a flap valve.
  • FIG. 4 is the schematic view of a valve when it is in closed position.
  • FIG. 5 is the schematic view of a valve when the cabinet interior pressure is lower than atmospheric pressure.
  • FIG. 6 is the schematic view of a valve while the fluid collected in the cabinet is discharged.
  • FIG. 7 is the schematic view of a valve comprising a stopper.
  • FIG. 8 is the schematic view of a valve in a closed position in an alternative embodiment of the present invention.
  • FIG. 9 is the schematic view of a valve when the cabinet interior pressure is lower than atmospheric pressure in an alternative embodiment of the present invention.
  • FIG. 10 is the schematic view of a valve while the fluid collected in the cabinet is discharged in an alternative embodiment of the present invention.
  • FIG. 11 is the schematic view of a valve comprising a stopper in an alternative embodiment of the present invention.
  • FIG. 12 is the schematic view of a valve in closed position attached to the discharge pipe by snap-fitting method.
  • FIG. 13 is the schematic view of a valve attached to the discharge pipe by snap-fitting method when the cabinet interior pressure is lower than atmospheric pressure.
  • FIG. 14 is the schematic view of a valve attached to the discharge pipe by snap-fitting method while the fluid collected in the cabinet is being discharged.
  • the cooling device ( 1 ) of the present invention comprises 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 opens into the cooling cabinet ( 2 ) and the other end outside the cooling cabinet ( 2 ), a valve ( 5 ) positioned inside and/or over the dischargepipe ( 4 ) , 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 at the same time providing the discharge of fluid collected in the cabinet ( 2 ), water resulting from defrost process for example, outside of the cabinet ( 2 ) ( FIG. 1 ).
  • the valve ( 5 ) comprises, each moving independently in different directions, a first flap valve ( 6 ) opening and/or closing the discharge pipe ( 4 ), allowing the flow of the ambient air into the cabinet ( 2 ) via the discharge pipe ( 4 ) when opened, and a second flap valve ( 7 ) on which the first flap valve ( 6 ) is mounted, moving to open in the opposite direction of the opening direction of the first flap valve ( 6 ), providing the discharge of the fluid in the cabinet ( 2 ) out of the cabinet ( 2 ) via the discharge pipe ( 4 ) ( FIG. 4 , FIG. 8 and FIG. 12 ).
  • a first and a second flap valve ( 6 and 7 ), one inserted into the other, is utilized in the valve ( 5 ).
  • the valve ( 5 ) comprises a hinge ( 100 ) providing the attachment of the second flap valve ( 7 ) on the inner wall of the discharge pipe ( 4 ), an opening ( 8 ) on the second flap valve ( 7 ) which is the first flap valve ( 6 ) opens, closes, and a hinge ( 101 ) providing the attachment of the first flap valve ( 6 ) on the second flap valve ( 7 ) ( FIG. 2 , FIG. 3 , FIG. 4 , FIG. 5 and FIG. 6 ).
  • the hinges ( 100 and 101 ) which movably attach the second flap valve ( 7 ) to the wall of the discharge pipe ( 4 ) to be opened or closed, and movably attach the first flap valve ( 6 ) on the second flap valve ( 7 ) to be opened or closed, allows the first and second flap valves ( 6 and 7 ) to be opened or closed with a minimum amount of force exerted on them.
  • the second flap valve ( 7 ) opens towards the atmosphere in the direction of the gravitational force as a result of the weight of the water collected on it.
  • the second flap valve ( 7 ) is formed in conformity with the structure of the discharge pipe ( 4 ) ( FIG. 6 , FIG. 10 and FIG. 14 ).
  • the first flap valve ( 6 ) opens towards the interior of the cabinet ( 2 ) in the direction of the air flow formed from high pressure side to low pressure when the cabinet ( 2 ) interior pressure is lower than atmospheric pressure ( FIG. 5 , FIG. 9 and FIG. 13 ).
  • first flap valve ( 6 ) and the second flap valve ( 7 ) can move independently.
  • the second flap valve ( 7 ) can be opened when the first flap valve ( 6 ) is closed, and the first flap valve ( 6 ) can be opened when the second flap valve ( 7 ) is closed.
  • the valve ( 5 ) comprises a stopper ( 9 ) situated on the inner wall of the dischargepipe ( 4 ) preventing the second flap valve ( 7 ) mounted on the inner wall of the discharge pipe ( 4 ) to move in a direction from the atmosphere towards the inside of the cabinet ( 2 ) ( FIG. 7 and FIG. 11 ).
  • the stopper ( 9 ) avoids the second flap valve ( 7 ) from opening in the other direction, that is, towards the inside of the cabinet ( 2 ).
  • the unbalancing of the cabinet ( 2 ) interior temperature and the cabinet ( 2 ) interior pressure by the inflow of ambient air which is warmer than the cabinet ( 2 ) interior is prevented ( FIG. 4 , FIG. 8 and FIG. 12 ).
  • the first flap valve ( 6 ) which is situated in the valve ( 5 ) that is normally in a closed position, opens without resisting to the inflow of atmospheric air that is higher in pressure compared to the cabinet ( 2 ) interior pressure and allows the inflow of air into the cabinet ( 2 ) when the cabinet ( 2 ) interior pressure drops below the atmospheric pressure due to the opening, closing of the cooling device ( 1 ) door ( 3 ) or for any other reason.
  • the air flows in through the end of the discharge pipe ( 4 ) opening to the ambient air into the discharge pipe ( 4 ), flowing through the gap opened by the first flap valve ( 6 ) and reaches inside the cabinet ( 2 ) from the end of the discharge pipe ( 4 ) extending into the cabinet ( 2 ) in this case.
  • the first flap valve ( 6 ) closes the discharge pipe ( 4 ) and disallows more air inflow into the cabinet ( 2 ) when the pressure exerted on the first flap valve ( 6 ) is lifted because the inflow of air stops is when the cabinet ( 2 ) interior pressure is equalized with the atmospheric pressure ( FIG. 5 , FIG. 9 and FIG. 13 ).
  • the valve ( 5 ) is attached to the end of the discharge pipe ( 4 ) by snap-fitting method.
  • the valve ( 5 ) is produced of preferably rubber material and the first and second flap valves ( 6 and 7 ) open, close owing to the elastic feature of the material only, without the need to use any hinges.
  • the valve ( 5 ) is produced in one-piece, 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 of the valve ( 5 ) and the discharge pipe ( 4 ) where the first and second flap valves ( 6 and 7 ) will be attached, whereby these sections with changed material thickness act as hinges ( FIG. 12 , FIG. 13 and FIG. 14 ).
