Description

  The present invention relates to a ventilation structure in a window portion that allows introduction of outside air while reliably preventing intrusion of rainwater or the like in a window portion such as a sash or a curtain wall.

  2. Description of the Related Art Conventionally, in a window portion such as a sash or a curtain wall, a structure in which a ventilator is provided to introduce outside air and ventilate is known.

  For example, in a curtain wall, as shown in Patent Document 1 below, in a curtain wall having a double window structure composed of an indoor shoji fitted with transparent glass and an outdoor shoji fitted with transparent glass, the double window is arranged as follows. The interior of the lower frame and the upper frame of the enclosing frame body is electrically connected to the inner portion of the double window, and the lower frame and the upper frame are provided with an indoor vent and an outdoor vent in the lower frame and the upper frame. There is disclosed a curtain wall window structure including a switching door that selectively closes one of the indoor vent and the outdoor vent and connects the other to the inner portion of the double window.

  Further, in Patent Document 2 below, an intake passage that communicates the atmosphere with the room is formed in a slanted portion at the lower part of the fitting window in a slanted shape with the indoor side positioned higher than the atmospheric side, and an arc-shaped cross section on the indoor side with the intake passage A curtain wall building ventilator is disclosed in which an opening / closing member is pivotally mounted so as to open and close an intake passage, and a handle protrudes from the opening / closing member into a room.

  In the following Patent Document 3, the lower frame of the upper shoji and the upper frame of the lower shoji are configured to have a space part surrounded by these, and a predetermined opening ratio is provided on the outdoor side and the indoor side wall part surrounding the space part. Has disclosed an sash ventilation device in which an opening is provided and rainwater is not directly blown into the indoor opening.

Further, in Patent Document 4 below, as shown in FIG. 25, a ventilation path for introducing outside air between the outer wall panel constituting the curtain wall wall surface and the horizontal frame 61 of the sash frame 60 adjacent to the height direction is provided. In the formed ventilation structure, a drainer 62 composed of a prospective piece 62a and a finding piece 62b having an expected width larger than the expected width of the horizontal frame 61 is joined to the horizontal frame 61 at a distance from the horizontal frame. Further, there is disclosed a curtain wall ventilation structure in which a ventilation path is formed between the horizontal frame 61 and the drainer 62 so as to communicate from the outside to the room.
