| (54) | Mechanism for pressure balancing |
| (57) Present invention relates to a mechanism for pressure balancing (2), activated by
using the movement of the doors (11) pulled towards the refrigerator(1)/freezer (3)
body under the influence of the vacuum formed due to the pressure difference resulting
from the inflow of the air into said refrigerator(1)/freezer(3), as a result of opening
and closing of the refrigerator(1)/freezer (3) doors (11), and enabling opening of
the door (11) without exerting a force greater than the normal one by allowing inflow
of the air into the refrigerator(1)/freezer (3) section until inner and outer pressures
are balanced, comprising at least an air duct (21) through which the ambient air proceeds
to be conveyed into the refrigerator (1)/freezer (3) by the action of the pulled door
as a result of the vacuum formed upon opening and closing of said door (11), at least
a movable piece (23) constituting the air inlet of said air duct (21), at least a
pushing part connected on the door (11), enabling conveyance of the ambient air into
the refrigerator(1)/freezer (3) through the formed opening by pushing said (26) movable
piece (23) towards the air duct (21), at least a spring (22) enabling the movable
piece that is pushed by said pushing piece (26) to head for backwards and enabling
the movable piece (23) to cover the air duct (21) inlet by taking its initial position
once the pressure balance is achieved.
