Description

[0001] The present invention relates to a ventilation fan device of a projection window,

The present invention relates to a ventilation device for a projection window, and more particularly, to a ventilation device for a projection window which is pushed outwardly in a state in which a knob is turned and installed, so as not to interfere with the opening and closing of the projection window, And to provide a ventilation device for a projection window which can reduce the work time and improve the working efficiency and can reduce the cost by a simple structure.

Generally, the ventilator is provided for discharging indoor air to the outside, and is provided with an electric motor having a rotary shaft, a ventilating fan rotating in conjunction with the rotation axis of the electric motor, and a housing surrounding the electric motor and the ventilating fan.

The ventilator having such a structure is usually used for the purpose of ventilating the inside of the toilet or underground of the building so as to exhaust the odor or moisture from the outside, and in recent years, And it is installed in the living room, the office or the room to discharge pleasant smell out.

In addition, for example, it is installed to discharge the smoke or odor generated when the cigarette smoke generated in the closed space such as the smoking room is discharged to the outside or when the food is cooked in the kitchen such as a kitchen or a restaurant in the home.

In order to install such a ventilator, it is necessary to drill a hole in the wall of the space where the ventilator is installed or the window of the windowpane, so that it is difficult and difficult to drill holes in the wall or the window, There is a problem in that the surroundings are damaged due to noise and dust.

In order to solve the problems in installing the conventional ventilator, the applicant of the present invention has disclosed a ventilating apparatus with a window frame, which is a registration window 20-0469494, in which a fastening hole is formed in an upper portion and a side wall, A base body which is bent and fixed by a piece to be fastened to the fastening hole on one side of a window frame on which a vent hole is formed so as to be installed with a window and a fastening member which is coupled to the ventilation hole of the base body, A bearing body disposed on the inner side of the support guide and connected to the other side of the support pieces connected to the inner wall surface of the support guide and connected to and supported by a rotary shaft axially installed in the bearing body, A ventilation fan that forms a space between the window and the window so as not to interfere with the opening operation and the closing operation of the ventilation fan, And a driving body for driving the rotating shaft to rotate the ventilation fan.

According to this conventional technique, a ventilator is installed without drilling a hole in a wall or a window, so that the installation property and workability of the ventilator are improved.

However, in the related art, there is a problem in that the sliding door, that is, both side windows are guided by the frame, can be installed in the sliding window that is opened and closed by the sliding method, but is not easily installed in the projection window.

Projection window means that a window provided with one window in one frame is pushed against the frame and opened or closed to close it. Since it is more airtight and soundproof than existing sliding window, , And is installed in an apartment.

In the case of such a projection window, since the window is opened in a state in which the handle is rotated, it is not easy to install a ventilation device installed in a sliding window which can open and close the window in a sliding manner.

Of course, even if the ventilation device installed in the sliding window is installed in the projection window, the projection window must be opened in order to allow the air in the room to be exhausted to the outdoor side by the operation of the ventilation fan. The projection window can not be opened, and eventually the air can not be exhausted even if the ventilator is operated.
