1. A method for drying, comprising:
- with a fan positioned within a confined space, generating an air stream within the confined space;
positioning a terminal lip surface of the confined space relatively stationary with respect to a substantially flat work surface to be dried, wherein the terminal lip surface is further defined by a periphery of the confined space adjacent to a terminus thereof and being offset a substantially constant distance in the range of two to five inches from the work surface;
exhausting the air stream from the confined space into a downstream zone defined between the confined space and the work surface and substantially bounded by the terminal lip surface;
directing the exhausted air stream across the work surface to be dried; and
exhausting the air stream from the downstream zone into ambient air space external of the terminal lip surface as an air stream positioned adjacent to the work surface.

Abstract
A method and apparatus for drying floors and carpets using a fan for generating a pressurized air stream within a vertical cylindrical shroud that is spaced two to five inches away from the floor on a set of legs such that an opening is formed between the shroud and the floor. The air stream is directed along the cylindrical shroud vertically toward the floor. At least a peripheral portion of the air stream is exhausted from the shroud in a substantially laminar flow at an angle that is inclined from the vertical and is exhausted radially into ambient air as a substantially laminar air stream.

11. A method for drying, comprising:
-
with a fan positioned within a confined space, generating an air stream within the confined space; positioning a peripheral lip surface of the confined space substantially perpendicular to a substantially flat and relatively stationary work surface to be dried and spaced away from the work surface an offset distance in the range of two to five inches; directing the air stream substantially crosswise to the work surface to be dried; and exhausting the air stream from the confined space between the work surface and the peripheral lip surface of the confined space and into ambient air space in a substantially radial pattern positioned substantially adjacent to the work surface. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)
