Description

  The present invention relates to a differential pressure canceling device for canceling a differential pressure when there is a pressure difference between the room and the outdoors.

  In a building, a pressure difference may be generated between the room and the outside, making it difficult to open the door. For example, when the wind is strong, the pressure difference between the outdoors and the room increases, making it difficult to open the door. Moreover, when the ventilation fan is operated indoors, the pressure in the room is lower than that in the outdoor, making it difficult to open the door. Several devices have been proposed as devices for eliminating such differential pressure (see, for example, Patent Document 1).

  FIG. 6 is a perspective view showing an example of the configuration of a conventional differential pressure canceling device. Reference numeral 100 denotes a shielding plate supported by a hinge 101 so as to be swingable. Reference numeral 102 denotes a screw rod. Reference numeral 103 denotes a handle for rotating the screw rod 102. Normally, the shielding plate 100 is configured such that the packing D is pressed against the inside and outside of the room, but the inside and outside of the shielding plate 100 are blocked. However, when the handle 103 is rotated in a predetermined direction, the shielding plate 100 is interposed via the screw rod 102. It moves in a predetermined direction, is separated from the packing D, and communicates between the interior and the exterior to eliminate the differential pressure.
