Description

  The present invention relates to a ventilation device having heat insulating properties attached to a window shoji.

  The ventilation device mounted on the upper edge of the window shoji is generally configured by assembling a plurality of aluminum molds, and the air flow in the ventilation passage formed therein is controlled by a flow control mechanism. However, in such a ventilator, the entire ventilator is cooled by the outside air, particularly when it is cold, and not only deprives the room of warm air but also causes condensation on the indoor side surface.

  Therefore, a ventilation device having heat insulation properties has been developed. In the ventilator disclosed in Patent Document 1, the outer main body arranged on the outdoor side is made of an aluminum mold material having weather resistance and mechanical strength, and the inner main body arranged on the indoor side is a resin excellent in heat insulation. It consists of mold material. The inner body has first and second projecting portions that are spaced apart from each other and project toward the outdoor side, and the outdoor outer edge portions of the first and second projecting portions are formed on the outer body. It is connected.

  In the ventilator disclosed in Patent Document 2, the outer main body and the inner main body are both made of an aluminum mold. Between the outer main body and the inner main body, first and second bridges made of resin mold materials separated from each other in the vertical direction are arranged. The outdoor edge and the indoor edge of the first and second bridges are connected to the outer body and the inner body.

  In the ventilation device of Patent Document 1, the inner main body is made of resin, and therefore, the outer main body has to bear mainly the mechanical strength. Increasing the depth dimension of the overhanging portion of the inner main body can enhance the heat insulation, but the mechanical strength of the entire ventilator is reduced. On the contrary, if the depth dimension of the overhanging portion of the inner main body is reduced and the depth dimension of the outer main body is increased, the mechanical strength can be ensured, but the heat insulation is reduced.

  Similarly, in Patent Document 2, if the depth dimensions of the first and second resin bridges are increased, the heat insulation can be improved, but the mechanical strength of the entire ventilator is reduced. On the other hand, when the depth dimension of the resin bridge is reduced and the total depth dimension of the metal outer body and the inner body is increased, the mechanical strength can be ensured, but the heat insulating property is reduced.

  As described above, it remains as a problem to ensure both heat insulation and mechanical strength at a sufficient level.

Since this spacer is made of resin, the thermal insulation of the ventilator is not reduced.

  Preferably, the outer main body and the inner main body integrally have a glass plate pressing portion protruding downward, and the glass main plate holding portions of the outer main body and the inner main body are arranged facing each other in the indoor / outdoor direction to accommodate the glass plate. A space is formed.

Has a horizontal plate portion arranged below the second bridge and the bridge piece, and a vertical plate portion along the outdoor surface of the glass plate pressing portion of the inner body, and the horizontal plate portion and the bridge The pieces are connected with screws.
According to the above configuration, even when the inner body made of resin and the first and second bridges are melted in the event of a fire, the metal outer body, the intermediate reinforcing member, the reinforcing plate, and the bridge piece are connected to each other. Since it remains, it remains in a state of being attached to the glass plate without being disassembled and falling off. Therefore, it is possible to prevent the flame from entering the room.

Preferably, the flow control mechanism includes a metal operation plate slidably supported by the outer body or the intermediate reinforcement member, and the ventilation port of the outer body or the intermediate reinforcement member is supported by the operation plate. Opened and closed.
According to the said structure, since an action | operation board is slid with respect to a metal outer main body or an intermediate | middle reinforcement member, the stable opening / closing operation | movement can be performed.

  According to the present invention, both heat insulation and mechanical strength can be secured at a sufficient level.
