An air discharge outlet comprises line air discharge outlets ( 35 ) and corner air discharge outlets ( 36 ). The line air discharge outlets ( 35 ) are so formed as to extend, respectively, along four sides of a casing bottom part having four side parts and four corner parts wherein the side and corner parts are formed in contiguous relationship to one another. The corner air discharge outlets ( 36 ) are formed, respectively, in the four casing corner parts so that each corner air discharge outlet ( 36 ) establishes connection between adjacent ones of the line air discharge outlets ( 35 ). And, each line air discharge outlet ( 35 ) is provided with a swing vane ( 38 ) swingable about a longitudinal shaft ( 41 ) of each line air discharge outlet ( 35 ). Each corner air discharge outlet ( 36 ) is provided with a fixed stationary vane ( 39 ). |
