Ventilator for easy assembly and improved exhaust of indoor air

A ventilator assembly comprising:

• a first element having a first straight inclined surface between a first opening and a second opening, the diameter of the first opening being less than the diameter of the second opening, wherein the first straight inclined surface has an angle of inclination of about 120° to about 130°;
• and
• a second element having a second straight inclined surface and an opening, the diameter of the opening of the second element being greater than diameter of the second opening of the first element, wherein the second straight inclined surface has a straight angle of inclination substantially similar to the angle of inclination of the first straight inclined surface;
• wherein the first element is adapted to be connected with the second element to form about a 7 cm gap between the first and second elements in such a manner that air flowing through the first and second openings of the first element also passes across the opening of the second element.

A method for ventilating a defined area, the method comprising the steps of:

• providing a first air current guide element having a first surface between a first opening and a second opening, the first opening being smaller than the second opening, wherein the first surface has a straight angle of inclination of about 120° to about 130°;
• providing a second air current guide element having a second surface with an opening, the opening of the second air current guide element being greater than the first opening of the first air current guide element, wherein the second surface has a straight angle of inclination substantially similar to the angle of inclination of the first surface, and a support pipe;
• positioning the opening of the second air current guide element towards the first opening of the first air current guide element;
• placing the support pipe between the first air current guide element and the second air current guide element, wherein the support pipe is about 5 cm to about 10 cm long to form a gap between the first and second air current guide elements;
• and
• coupling the second air current guide element to the first air current guide element.
