Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a window ventilation fan, in which a heavy ventilation fan body is installed on the floor side, a rectangular cylindrical shielding panel is movably provided on the ventilation fan body, and To provide a window ventilation fan that can take in contaminated air and exhaust it outdoors and can be easily moved.

As shown in FIG. 1, in a conventional window ventilation fan, the ventilation fan main body 101 is located at the top, so the shielding panel 102 that supports the heavy ventilation fan main body 101 is fixed by screws 103 etc. while being pulled up and down. ing. Therefore, since the heavy ventilation fan main body 101 is placed at the top, it becomes unstable, and it is necessary to use a mounting device to securely mount the fan, which makes it difficult to move it easily. Therefore, it was inconvenient that the ventilation fan could not be easily moved and installed in another room.

The present invention solves the above-mentioned conventional drawbacks, and embodiments thereof will be described below with reference to FIGS. 2 and 3.

In the figure, reference numeral 1 denotes a box-shaped ventilation fan main body, which has an exhaust port 2 on the back surface and a cylindrical intake port 3 that projects upward at the rear of the top surface. A blower 4 is provided within the ventilation fan body 1 so as to take in air through an intake port 3 and exhaust air through an exhaust port 2, and an orifice 5 is provided outside the blower 4. A handle 6 is provided on the upper surface of the ventilation fan body 1, and an elastic body 7 with high frictional resistance is provided on the inner surface near the end of the intake port 3. A cylindrical shielding panel 8 is provided at the intake port 3 so as to be vertically slidable. The upper surface of this shielding panel 8 is closed, the inside communicates with the inside of the ventilation fan main body 1, and an indoor air intake port 9 is provided in the upper part of the front surface. In addition, 10 in the figure is the window frame, 1
1 is the floor and 12 is the door.

In the above configuration, when installing the ventilation fan, place the ventilation fan body 1 on the floor, move it slightly toward the window frame 10, and move the shielding panel 8 upward against the frictional resistance of the elastic body 7 provided on the inner surface of the intake port 3. The shielding panel 8 is moved, and at a position where the upper end of the shielding panel 8 comes into contact with the upper side of the window frame 10, the shielding panel 8 is supported by the frictional resistance of the elastic body 7, and a ventilation fan is installed. In this case, window frame 10
A door 12 provided in the ventilation fan body 1 is left open by approximately the width of the ventilation fan body 1. When the ventilation fan installed in this manner is operated, contaminated indoor air is drawn into the shielding panel 8 from the indoor air intake port 9, passes through the intake port 3 of the ventilation fan body 1, is sucked into the orifice 5, and is sucked into the blower. 4, the air is exhausted outdoors from the exhaust port 2. On the other hand, the opening of the door 12 is closed by the ventilation fan body 1 and the shielding panel 8. Next, when you want to move the ventilation fan to another room and install it, move the shielding panel 8 downward and remove the handle 6.
Lift the ventilation fan main body 1, move it to the room where it will be newly installed, and install it by operating as shown above. Note that when the shielding panel 8 is pushed down during movement, the lower end of the shielding panel 8 comes into contact with the orifice 5 at the lowest position and is prevented from coming into contact with the blower 4.

As described above, according to the present invention, the ventilation fan can be installed by simply placing the ventilation fan body on the floor and extending the shielding panel that is movably provided on the upper side of the ventilation fan body to match the height of the window. It is also easy to move. Further, since the suction port is provided in the upper front part of the shielding panel, the air in the upper part of the room where contaminated air is floating is sucked in and exhausted, and the room can be efficiently ventilated. Furthermore, since the blower is housed inside the ventilation fan body, it is safe because it cannot be touched by people, and the operating noise is attenuated and propagated into the room.
