Title:
STRUCTURE OF AIR OUTLET OF AIR CONDITIONER
Document Type and Number:
Japanese Patent JP3116874
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To prevent dew formation on a guide vane in an air outlet in air conditioner such as an air conditioner.
SOLUTION: In a air conditioner wherein the sections of inside and outside passage walls 72 and 71 forming an air outlet 7 are shaped like radiused faces directed from the vertical direction to the horizontal and an airflow guide vane 20 having a radiused face directed from the vertical direction to the horizontal is provided between these passage walls, the radius r1 of curvature of the wall 71, the radius r3 of curvature of the wall 72 and the radius r2 of curvature of the vane 20 are set in the relations of r1≤r2≤r3. At the maximum angle of deflection (at the time of horizontal blow) of the vane 20 in cooling, according to this constitution, a distribution ratio between the quantity Q1 of air flowing through an outside passage 7a formed by the vane 20 and the quantity Q2 of air flowing through an inside passage 7b can be controlled to be 1.5≥Q1/Q2≥1 so as to prevent dew formation in the downstream part on the rear side of the vane. In this distribution ratio, no airflow separation occurs in the downstream part on the rear side of the vane 20 and thus such dew formation as usual hardly occurs.
