Description

   Ventilator   

The invention relates to a ventilation device.

Some of today's buildings have ventilation devices for ventilating between indoors and outdoors without opening windows. The ventilation device is a device attached to the main window in the form of a horizontal window or a vertical window. For example, as a ventilating device for horizontally connected windows, there are devices having a frame having a smaller left and right width than a window, and an internal panel that opens and closes the opening of the frame on the indoor side. Based on a building having such a ventilation device, it is possible to open the inner panel at night or when not at home for ventilation at night without causing a problem in theft prevention, and it is possible to reduce the load of the air conditioner (for example, see Patent Literature 1 ).
