A wind direction adjuster 18 that is rotatably pivotally mounted, and an air volume adjusting device 10 is provided above the wind direction adjuster 18. As shown in FIG. 1 and FIG. 2, the outlet frame 16 includes trapezoidal vertical frame plates 20, 20 facing each other, and upper surface portions of the vertical frame plates 20, 20 so as to shield a gap between the vertical frame plates 20, 20. And a connection hole 24 is connected to the central portion of one of the vertical frame plates 20, and a ceiling rack is attached to the lower part of the outer surface of the vertical frame plates 20 and 20. A pair of left and right inverted L-shaped plates 28, 28 for supporting the members 26, 26 are provided. As shown in FIGS. 2 and 4, the wind direction adjuster 18 is at a lower position in the outlet frame 16 and has a top shaft 30 rotatably supported on inner surfaces of both sides of the spacing plate 22. Both ends of a pair of arc-shaped long plates 32 and 32 are substantially symmetrically locked to the outer peripheral surfaces of the top shafts 30 and 30. The airflow passing through the upper opening and the lower opening of the arc-shaped long plates 32, 32 is blown out along the ceiling surface by tilting and rotating the top shafts 30, 30, or in the vertical direction perpendicular to the ceiling surface. It is blown out and the blowing direction is adjusted.

A feature of the present invention is that the air flow rate adjusting device 10 is installed above the wind direction adjuster 18 to adjust the air flow rate. As shown in FIG. 2 to FIG. 3, the air volume adjusting device 10 includes a fixed frame 36 which is installed in the outlet frame 16 in a closed shape and has a flow port 34 for cold air or warm air. And a movable frame 38 mounted slidably in the longitudinal direction of the fixed frame 36. The fixing frame 36 is formed of a thin metal plate as a material in an inverted U shape in an end view, and a plurality of rectangular flow ports 34 are opened in a plane portion 40 in the longitudinal direction thereof. The side plates 42, 42 bent downward from both edges of the flat portion 40 of the fixed frame 36 are provided with a plurality of screws 44, 44 from the outer surface of the vertical frame plates 20, 20 of the outlet frame 16. It is worn.

As shown in FIGS. 2 and 4, the movable frame 38 is made of a thin metal plate as the fixed frame 36, and can be slid in the longitudinal direction in close contact with the inner surface of the fixed frame 36. Similarly, the end face is formed into an inverted U shape, and a plurality of adjusting ports 48, which have the same shape as the flow port 34 of the fixed frame 36 and communicate with each flow port 34, are formed in the longitudinal plane portion 46. . Further, the side plates 50, 50 bent downward from both edges of the flat part 46 of the movable frame 38 are engaged with the ends of the screws 44, 44 screwed to the side plates 42, 42 of the fixed frame 36. The plurality of elongated holes 52, 52 are opened. The movable frame 38 is supported on the inner surface of the fixed frame 36 while the elongated holes 52, 52 are engaged with the screws 44, 44, and the adjusting port 48 is connected to the flow port 34 of the fixed frame 36 as shown in FIG. From this state, the movable frame 38 can be slid by the length of the long hole 52, and the amount of air passing through can be adjusted by changing the communication area S between the ventilation port 34 and the adjustment port 48. A sliding knob 54 hangs down from the lower surface near the one end of the movable frame 38, and a stopper 56 projects from the upper surface near the one end through the flow port 34 of the fixed frame 36.

The line-type air outlet 12 having the air volume adjusting device 10 according to the present invention therein is linearly provided at a predetermined position of a ceiling plate 60 of the system ceiling 58, as shown in FIG. 2, for example. The lower end of the outlet frame 16 is fitted into the opening, and the lower end portions of the ceiling plates 60, 60 and the lower edge portions of the outlet frame 16 in the longitudinal direction of the outlet frame 16 are received by the T-shaped ceiling racks 26, 26. The line-shaped outlet 12 is linearly arranged on the system ceiling 58 while being attached and supporting the inverted L-shaped plates 28, 28 attached to the outlet frame 16 on the upper ends of the ceiling racks 26, 26. Then, the flexible duct 62 extending from the main duct arranged in the ceiling is connected to the connection port 24 of each line-type outlet 12, and cold air or warm air is blown into the hollow air outlet frame 16 from this main duct. At the position of the air flow rate adjusting device 10, the air flow rate is adjusted while passing through the communication part between the air flow opening 34 of the fixed frame 36 and the adjustment port 48 of the movable frame 38, and the air flow direction is further adjusted downward. While adjusting the blowing direction by the device 18, the air is blown into the room from the air outlet 14 at the lower end to achieve air conditioning in the room. When adjusting the amount of air blown out according to the indoor conditions, the wind direction adjuster 18 provided close to the air outlet 14 is provided so that the lower opening and the upper opening of the pair of arc-shaped long plates 32, 32 are in the vertical direction. After adjusting the rotation so that it is located at the position, insert a rod or the like through this opening from the outlet 14 side, and use the knob 54 hung at one end of the movable frame 38 of the air volume adjusting device 10 as shown by the arrow. When sliding in the direction of the end of 16, the communication area S between each flow port 34 of the fixed frame 36 and each adjustment port 48 of the movable frame 38 is reduced, and the air volume of the passing air flow is reduced. When the movable frame 38 is slid in the opposite direction from the reduced state of the area S, the air volume of the airflow passing therethrough is increased. After properly adjusting the air flow rate adjusting device 10, the air flow direction adjuster 18 is rotated to adjust the blowout direction. The airflow blown out from the blowout port 14 is adjusted by a simple operation of sliding the movable frame 38. It will be possible. Since the solid frame 36 and the movable frame 38 are long plate-shaped frames, the air volume control device 10 can be easily installed in the narrow outlet frame 16 and can be manufactured at a low cost. By sliding the frame 38, the amount of air blown from the outlet 14 can be adjusted, and the air conditioning according to the indoor condition can be easily adjusted.

In addition, as another embodiment included in the present invention, the shapes of the fixed frame 36 and the movable frame 38 are not limited to the inverted U-shape, and the shapes shown in FIGS. As shown in the end view, the ventilation port 34 is opened on both inclined surfaces of the mountain-shaped fixed frame 36a, and the mountain-shaped movable frame 38a is also arranged on the inner surface of the fixed frame 36a. The adjusting port 48 opened on the surface may be connected to the flow port 34. As shown in FIGS. 7 and 8, a movable frame 38b, which is also semicircular in end view, is arranged on the inner surface of the fixed frame 36b, which is semicircular in end view, to open the flow port 34 and the adjustment port 48, respectively. It is also possible to make them communicate with each other. Further, as shown in FIG. 9 and FIG. 10, a prismatic movable frame 38c made of foam material is fitted into a fixed U-shaped fixed frame 36c in end view, and a large number of circles are attached to the fixed frame 36c. It is also possible to provide the flow port 34 formed of a hole and the adjustment port 48 also formed of a circular hole in the movable frame 38c so as to increase or decrease the communication between the flow port and the adjustment port by sliding the movable frame 38c. is there.
