Abstract

PURPOSE:To enable to blow out air in a downward direction without loss of air flow, by employing such an arrangement that an auxiliary air-flow deflector disposed at an air outlet port of an air conditioner is partially projected outwards from the lower edge of the air outlet port and extends tangentially of a circle concentrical with the curvature constituting the contour of the lower edge portion of the air outlet port. CONSTITUTION:A main air-flow deflector 5 and auxiliary air-flow deflectors 8, 9 are disposed in an air outlet port of an air conditioner which is defined by a rear casing 2 and a front casing 3. Here, arrangement is such that the lower, auxiliary air-flow deflector 8 is partially or entirely protruded outwards from the top 11 of the lower edge portion 10 of the rear casing 2 and its angular position is located on a tangential line 14 of a concentric circle 13 having the same curvature 13 as the lower edge portion 10 when it is set in a downward direction. By employing such an arrangement, air flowing under the auxiliary deflector 8 is made to flow along a curved section 12 as shown by e in the drawing and constitutes a main downward flow (h) together with air flow (g) along the main air-flow deflector 5.

, 6 are extended to form the air outlet 4. 5 is a wide main wind direction plate for changing the wind direction up and down, and 6 is an auxiliary wind direction plate. In such a structure, the wind direction is downwardff'

合わせてことにより、流れを損失無く下向きにできるも
のである。Since the auxiliary wind direction plate 6 is installed within the radial direction of the rear casing 2, the effect of directing the airflow C flowing near the casing 2 downward is small, and the effect of accelerating it in the horizontal direction is large. Therefore, the blowout angle θ2 of the main stream d is upward than the certified angle θ1 of the main airflow direction plate 5, and a part of the comfort auxiliary airflow direction plate that heats the floor from the floor during heating operation is projected forward from the lower edge of the air outlet. By aligning the arrangement with the concentric circle of the curvature of the lower edge, the flow can be directed downward without loss.

易の下側の補助風向板であり、下向きにセットした時、
下縁１０の先端１１よりも一部あるいは全体が突出し、
曲率部１２の同心円１３の接線１４上に設置されている
。It is an auxiliary wind direction plate on the lower side of the camera, and when set facing downward,
A portion or the whole of the lower edge 10 protrudes beyond the tip 11,
It is installed on the tangent line 14 of the concentric circle 13 of the curvature portion 12.

このような構造にすることにより、ケーシング２付近の
気流ｅは補助風向板８の下向き気流ｆ［より押し下げら

ため曲率部１１に沿って流れ、加速されることになる。With this structure, the airflow e near the casing 2 is pushed down by the downward airflow f[of the auxiliary wind direction plate 8, and since the lower edge 10 is located behind the auxiliary wind direction plate 8, it is pushed down along the curvature part 11. It will flow and be accelerated.

空気はその流れに誘引される性質があり、吹出口４上方

度らを主風向板５の角度０１に近づけることができる。In addition, when the air flow reaches a steady state with one end curved, the air in the vicinity tends to be attracted by the flow, and the air flow g above the outlet 4 also joins the air flow e, forming a main flow, and the air flow is The angles can be brought closer to the angle 01 of the main wind direction plate 5.

FIG. 3 shows another embodiment in which the front side 16 of the main wind direction plate 15 is bent and a recessed notch 18 is provided on the lower surface 17 to direct the upper airflow 1 further downward.
