PURPOSE:To enable prompt air conditioning with air sufficiently blown diago nally in the lower direction for a horizontal surface by forming a blow port, opened to the diagonal lower of an upper diffuser, further providing a protrusive streak in the upper diffuser spread to the blow port. CONSTITUTION:Air is sucked from a blow port 3 into both upper and lower cases further with a heat exchange performed in an evaporator 15, thereafter the air, which crosses through the inside of a cylindrical impeller 5, is blown out from a blow port 4. One of air which passes through the cylindrical impeller 5, that is, air in the vicinity of an upper diffuser 7 is partly blown (arrow a) in a direction of the front surface of a device main unit without moving along the guide surface of a protrusive streak 8. On the other hand, air passing in the vicinity of the upper diffuser 7 is exfoliated from a curved surface of the upper diffuser by the protrusive streak 8 and deflected (arrows b, c) diagonally in the downward direction. Air, which passes in the vicinity of the center of the impeller from a lower diffuser 11 of the blow port 4, is blown (arrows d, e) diagonally in the downward direction being influenced by the above described directional air (b, c). |
