Abstract

PURPOSE:To reduce the uneven room temperature distribution by disposing fixed vanes in the lengthwise center of an elongate air outlet and movable vanes on both sides of said fixed vanes. CONSTITUTION:Fixed vanes 27 are fixed in place perpendicularly to the length of an air outlet 28 in the outlet frame 26. Because of this, the air delivered through the central area of an outlet 13 in the cosmetic panel 11 is guided nearly directly downward. By adjusting movable vanes 29 in the direction desired by users, the air delivered through both sides of the outlet 13 is guided in that direction. In such an occasion, the movable vanes 29 will not be titled toward the fixed vanes 27 on account of a stopper 37 on a link plate 32. Therefore, the airflow guided directly downward by the fixed vanes 27 and the airflow guided by the movable vanes 29 will not be mixed. Since the airflows delivered out of the outlet 13 do not converge and collide, the uneven room temperature distribution can be reduced.

As shown in FIG. 2, this interlocking plate 32 has a stopper piece 37 extending in the lateral direction of the air outlet 28. In the left blade group 35, this stopper piece 3γ is on the right side surface 38 of the blade 29, and the stopper piece 3γ 36, this stopper piece 37 comes into contact with the left side surface 39 of the blade 29. That is, the blades 29 of the left blade group 35 are restricted from rotating to the right (toward the fixed blade 27), and the blades 29 of the right blade group 36 are restricted from rotating to the left (toward the fixed blade 27). (See solid arrow).

40 is a guide piece for positioning the air conditioner 1 on the ceiling 44, one end 41 is fixed to the recessed part 42 of the blow-off frame 26, and the other end 43 protrudes to the outside of the blow-off frame 26, as shown in FIG. It is applied to the ceiling 44.

In many cases, a lighting fixture is installed at the center of the ceiling 44 in the room of an ordinary household, so the above-mentioned air conditioner is installed at the ceiling 44 as shown in FIGS. 5 and 6.
It is often installed at a position away from the center of the wall 45, that is, close to the wall surface 45. In this case, the ceiling 44 should be placed so that one outlet 13 is on the wall side and the other Suita outlet 14 is on the center side of the room.
Install this air conditioner 1 at In the air conditioner 1 installed in this way, when the cross flow fan 4.5 and the electric motor 22 are operated, indoor air is sucked in through the suction grill 12 of the decorative panel 11, and the air is drawn into the heat exchanger 6,
The temperature is controlled at 7 and discharged from the two outlets 13° and 14.
(See solid line arrow in Figure 1). At this time, the wind discharged from one outlet 13 is moved by the second guide vane 18 to this outlet 1.
3 in the downward longitudinal direction.

Here, since the fixed blade 27 is fixed in a direction perpendicular to the longitudinal direction of the air outlet 2B of the air outlet frame 26, the decorative panel 1
The wind discharged from the vicinity of the center of the first outlet 13 is guided almost directly downward. Furthermore, by tilting the movable blades 29 in a direction desired by the user, the wind discharged from the vicinity of both ends of the Suita mouth 13 is guided in that direction.
The movable blade 29 is moved to the fixed blade 2 by the stopper piece 37 of 2.
It will not lean towards the 7 side. Therefore, as shown in FIGS. 5 and 6, there is no possibility that the wind guided directly downward by the fixed blade 27 and the wind guided by the movable blade 29 will collide with each other.

Further, the flow of air discharged from the other Suita port 14 is guided toward the center of the chamber while being changed in the vertical direction by the swinging of the looper 19. The above-mentioned wind flow is as shown by the solid line arrows in FIGS. 5 and 6.

In the above embodiment, the fixed blade 2T is fixed in a direction perpendicular to the longitudinal direction of the air outlet 28, and each movable blade 29 is restricted from moving toward the fixed blade 27 (II).
The present invention is not limited to such movement or fixation of the blades. For example, if this air conditioner 1 is to be fixed at the upper left corner of a room, the fixed blades are tilted to the right (center side of the room) and fixed, and the movable blades 2 on the left side are fixed.
9 may be inclined toward the fixed blade 27 side.

(G) Effects of the Invention As described above, the present invention has a fixed blade in the longitudinal center of the elongated air outlet, and movable blades on both sides of the fixed blade, so that the air flow from the air outlet is improved. There is little risk that the discharged winds will come together and collide with each other, and it is possible to keep temperature fluctuations in the room to a small level.

In addition, if the fixed blade is fixed in a direction perpendicular to the longitudinal direction of the air outlet and the movable blade is prevented from tilting toward the fixed blade, the air discharged from the air outlet can be discharged more uniformly. It is possible to suppress the occurrence of temperature fluctuations in the room.
