As shown in the figure, the air outlet 2 is provided with upper and lower wind direction plates 12 and 13 and a motor (not shown) for rotating the upper and lower wind direction plates 12 and 13. There is a type in which horizontal blowing is performed by automatically setting the horizontal blowing position (FIG. 6), and performing diagonally lower blowing by automatically setting the diagonally lower blowing position (FIG. 7) during the heating operation. By the way, in the prior art, as shown in Japanese Patent Application Laid-Open No. 63-54549, the wind direction plate closed the outlet 2 as shown in FIG. . However, since the air outlet is closed immediately after the heating operation and the air outlet is closed, warm air is trapped, and the temperature of electric components such as the heater 9 rises, causing a problem in reliability.
