Description

[Detailed Description of the Invention] The present invention relates to an exhaust air guide device in an indoor ventilation system.

Indoor ventilation is necessary, but in ordinary homes, ventilation systems cannot be installed due to problems with the appearance of the room, so ventilation is achieved by opening and closing window shoji.

Recently, bay windows are often installed in rooms, and we have conducted various studies to use these bay windows for ventilation, and have devised a method of ventilation using forced exhaust, but the exhaust duct has to be significantly deformed. This created a problem in that the load on the fan increased, making it impossible for the duct to undergo large deformations, and a new problem arose in that the nose comb became an obstacle to exhaust air.

Therefore, the inventor of the present invention has conducted repeated research in order to perform exhaustion smoothly, and as a result, he has found a means that can perform exhaustion with a simple device and also reinforce the nose comb, and has proposed this as the present invention.

To explain the structure of the present invention in detail based on the embodiment shown in the drawings, the bay window A includes vertical sleeve frames 1, 1 on both sides, both corner mullions 2, 2, upper and lower sleeve frames 3, 4, and upper and lower window frames 5. , 6.
