Definitions

  • the present invention relates to refrigerator doors.
  • the present invention particularly relates to a mechanism for balancing the pressure eliminating the need for a waiting period in order for the refrigerator door to be opened for the second time due to the pressure difference between the refrigerating section and the outer environment, resulting from the vacuum formed during opening and closing of the freezer doors of the refrigerators.
  • JP2000111237 A Japanese Patent Application numbered JP2000111237
  • Said invention relates to the structure of the opening section developed for preventing the deformation of the freezer door due to the temperature and pressure difference of the air, inside and outside of the freezer.
  • European Patent application numbered EP2059737 (B1 ) relates to a freezer.
  • Said invention comprises a housing having a body surrounding a cooler inner area and a door and a pressure-balancing valve.
  • Said valve allows inflow of the air from the outside environment to the inner area and prevents outflow of the air from the inside area.
  • Another invention is a German patent application DE10203425 (A2 ) .
  • This invention relates to an assembly formed on the door or the body and balancing the pressure between the inner chamber and outside of the refrigerator. Said assembly is activated, however, by manually controlling a valve mounted on the body or the door.
  • DE29912563 (U ), EP0598979 and EP1174668 disclose mechanisms in which the body is moved and the refrigerator door is easily opened by moving the arm that is movable around an axis upon rotating thereof.
  • Present invention relates to a mechanism for pressure balancing meeting the aforementioned requirements, overcoming all the inconveniencies and providing further advantages.
  • An object of the invention is to employ a mechanism for pressure balancing enabling re-opening of the freezer door easily following opening and closing thereof once.
  • a mechanism for pressure balancing enabling re-opening of the freezer door easily following opening and closing thereof once.
  • Another object of the invention is to prevent the problematic opening of the door due to the vacuum formed inside the freezer section resulting from opening and closing of the doors of the freezer sections of the refrigerators.
  • present invention relates to a mechanism for pressure balancing
  • said mechanism for pressure balancing comprises at least one hermetic element, preferably a gasket, which prevents further inflow of the air into the refrigerator/freezer upon balancing the inner and outer pressures in the refrigerator/freezer section.
  • Mechanism for pressure balancing in order to achieve mentioned objectives, comprises at least a grate connected to the tip through which the air coming from said air duct enters into the refrigerator/freezer section.
  • Refrigerator 23 Movable piece 11.
  • Door 24 Hermetic element 12.
  • Door profile 25 Grate 13.
  • Hermetic element 26 Pushing piece 14.
  • Mid strap 27 Front door 2.
  • Pressure balancing mechanism 28 Spring housing 21. Air duct 29. Opening 22. Spring 3 . Freezer
  • Mechanism for pressure balancing (2) facilitates re-opening of the door (11) of the freezer section (3) of a refrigerator (1) following an opening and closing.
  • said freezer section (3) in case that the inner and outer pressures are balanced, the door (11) of the freezer section (3) becomes parallel to the freezer (1) body.
  • the door (11) can be easily opened in succession as well.
  • the door profile (12) is positioned so as to be parallel to the freezer (1) body in its initial position, after the first opening and closing.
  • Said mechanism for pressure balancing (2) comprises;
  • FIG. 1 and Figure 2 a general view of the refrigerator (1) and a detailed view of the mechanism (2) for pressure balancing used in the freezer section (3) are given respectively.
  • a pushing piece (26) attached on the door profile (12).
  • Said pushing piece (26) pushes the movable piece (23) in the mechanism for pressure balancing (2) by the angular movement of the door (11) during closing of the same.
  • This pushing action presses the springs (22) attached to the movable piece (23) via spring housings (28) backwardly.
  • the air enters into the freezer section (3) over the grate (25) by passing through the said air duct (21).
  • air inflow here is a desired phenomenon, carried out in a controlled manner. Inflow of air continues until the inner and outer pressure balance is achieved.
  • FIG 6 the position of elements of the mechanism (2) for pressure balancing is shown before the door (11) of the refrigerator (1) is opened and closed.
  • springs (22) exert a pressure to the moving piece (23).
  • the hermetic element, gasket (13), on the door (11) is in its first position, so a compression caused by a vacuum is beside the point. Therefore the door (11) is closed and there is no air flow into the freezer (3).
  • a vacuum occurs. This vacuum causes the door (11) of the freezer section (3) to get closer to the body.
  • the pushing piece (26) on the door (11) creates an opening (29) by contacting with the moving piece (23). This case is shown in details in Figure 7 .
  • position of the pushing piece (26) on the door (11) is shown. Due to the position of the said pushing piece (26) on the door (11), it cannot push the moving piece (23) in case that there is no vacuum formation.
  • a front door (27) is used to constitute the inlet of the mentioned pressure balancing mechanism (2).
  • There is a built-in hole on that front door (27) that allows air inflow which is a fixed piece mounted to the mid strap (14).
  • the element here that prevents air inflow is the hermetic element (24) on the moving piece (23) which closes the hole by pressing to it by means of the force of the springs (22).
  • the numbers and sizes used of the elements used in the mentioned pressure balancing mechanism (2) may vary in an alternative embodiment of the present invention. It is available to be used on equipment with a door (11) and a hermetic element (13) that can face vacuum problems. In order for this embodiment of the present invention to serve as an example, it is explained in a way to solve the vacuum problems of the doors (11) of the refrigerators (1), especially those of the freezers (2).
