Description

The present invention relates to a ventilation device. In particular, the present invention relates to a ventilation device that can be attached to an opening such as an existing window or door to provide ventilation between the inside and the outside of the opening.

Ventilation of closed spaces is said to be effective as a countermeasure against infectious diseases. Particularly in recent years, there is a strong demand for ventilation even in home rooms and offices where ventilation has not been required so far.

The easiest way to ventilate is to open windows and doors. However, it may be difficult to open windows and doors because the room is being cooled or heated, or because it is desired to avoid being peeped into the room from the outside. Ventilation fans may be installed as a means of ventilation when windows and doors cannot be opened.

In many cases where a new ventilation fan is installed, installation work is required. Therefore, there is a demand for a ventilation fan that can be installed by a simpler method without the need for construction work. Patent Document 1 discloses a ventilation window panel device capable of retrofitting a ventilation fan to an existing window frame or sash window itself. The ventilation window panel device of Patent Document 1 is a device attached to a window provided with a sliding door in the window frame, and can be freely attached to and detached from the gap between the window frame and the sliding door with either one of the sliding doors half-opened. Can be installed. In the device of Patent Document 1, a ventilation fan is attached to a rectangular plate-shaped member, and a fitting member for fitting with the frame portion of the sliding door is provided at either one of the left and right ends of the plate-shaped member. The end is provided with a closed fin portion that abuts on the window frame.

The window to which the ventilation window panel device of Patent Document 1 is attached cannot be locked as it is because the sliding door is half-opened. To lock, additional locking means must be provided or the ventilation window panel device must be removed each time it is locked. However, since the device is attached by fitting it with the window frame, it takes time and effort to attach and detach it.
