Description

{A ventilation equipment built in window}

More particularly, the present invention relates to an indoor air ventilating apparatus, and more particularly, to an indoor air ventilating apparatus which can open and close windows without causing holes in a wall or a window, It is possible to prevent the inflow of outside cold air in winter and to operate one or more ventilating fans by using a single driving body to obtain an economical effect .

Generally, the ventilator used for discharging indoor air to the outside is constituted of an electric motor having a rotary shaft, a ventilating fan rotated by engaging with the rotary shaft of the electric motor, and a protective housing and a cover surrounding the electric motor and the ventilating fan .

The ventilator having such a constitution is usually installed in a toilet or a basement of a building to be used for exhausting the odor and moisture to the outside of the building. In recent years, It may be installed in a living room, an office, or a room to release a pleasant smell.

In addition, the ventilator is installed in a smoking room or the like to easily exhaust cigarette smoke generated when a cigarette is smoked in a closed space such as a smoking room.

In order to install the ventilator, ventilators should be installed by drilling a hole in a wall or a window of the space where the ventilator is installed so that the air and odor of the room are exhausted to the outside by the rotation operation of the ventilating fan.

As a result, there is a problem in that it is difficult and time-consuming to drill a hole in a wall or a window, and the surroundings are damaged due to noise and dust generated in the process of drilling the hole.

In addition, in order to drill a hole in a window, a specialist has to work directly, and the problem of breaking the glass of the window in the process of drilling the hole frequently occurs.

Of course, in the case of a window, the window may be opened to open a part of the window frame, and then a fan may be installed in the space between the opened window and the window frame. However, in this case, Therefore, there is an inconvenience that additional work must be performed.

Furthermore, although the ventilator is installed on the window sill of the window and the remaining space is covered with the styrofoam or plate material, since the remaining space is blocked by the styrofoam or the plate material, the outside cold air enters the room through the styrofoam or the plate Accordingly, there is another problem in that the indoor temperature is increased due to heat loss in the room and the open space of the window in the summer.

In addition, in the case of the installed ventilator, since the space in which the ventilating fan of the ventilator is located is always kept open, hot cold air of winter or hot air of summer enters the room, In the case of summer, pests such as mosquitoes and flies are also introduced.
