As described above, according to the present invention, warm air and cold air
Adjustments can be made so that the optimum amount of air is blown out in the optimum direction.
First, the blowing of warm air / cold air when the air conditioning blowing structure of the present invention is used for a ceiling wall will be described. When hot air is blown out from the outlet through the air passage, either the first plate or the second plate is rotatably provided at the outlet or both the first plate and the second plate are rotatably provided. The wind direction adjuster is rotated by a worker so as to rotate the first plate, the second plate, or both the first plate and the second plate so that the vent holes of the first plate and the second plate are not displaced. A large amount of air is blown downward from the superposed and warm air through each of the superposed vents to efficiently warm the room from below. In this case, since the warm air is blown downward through the vent holes of the plates that are almost overlapped with each other, a small amount of warm air is blown from the outer periphery of the air flow direction adjuster and the outer peripheral blowing space provided at the periphery of the air outlet. When the cool air is blown out from the air outlet through the air passage, the operator rotates the first plate or the second plate or both the first plate and the second plate which are freely rotatable in the same manner as described above. If the phase is changed so that the vent of the moved plate and the vent of the other plate are completely displaced, the vent of the first plate moves so as to overlap the non-opening portion of the second plate, and the vent of the second plate moves. The non-opening part of the first plate to be rotated is moved so as to overlap with the vent hole, and the vent holes of the other plates are closed by the non-opening part of the opposing plate, and all the cool air coming through the ventilation passage is The airflow direction adjuster with its ventilation port closed closes, and the airflow direction adjuster installed almost in parallel with the ceiling wall blows the hot air into the outer blowing space, which is always open on the outer circumference of the airflow direction adjuster. Release Guided to Jo, guided cold air is blowing radially in a direction along the ceiling wall through the outer peripheral outlet space, will cool efficiently the room from above. When hot air or cold air is simultaneously blown downward and laterally along the ceiling wall, the operator can rotate the first plate or the second plate or both the first plate and the second plate by a predetermined phase rotation. The non-opening portion of the second plate is overlapped by a predetermined area of the vent hole of the first plate, and the non-opening portion of the first plate is overlapped by the predetermined area of the vent hole of the second plate. By adjusting the air flow direction controller according to the state, the wind direction of the warm air or the cold air can be blown downward and laterally along the ceiling wall. Also, if the operator adjusts the air flow direction controller to gradually change the opening area of the vent hole of each plate, the air volume to be blown downward or laterally can be changed, and a predetermined air volume or direction can be obtained. .

The air conditioning blow-out structure of the present invention may be used not only on the ceiling wall but also on the side wall. In this case, when blowing cold air, the operator adjusts the air flow direction adjuster to close the ventilation holes of each plate, and the cold air that hits the air flow direction adjuster is radiated from the outer peripheral blowing space along the side wall. Just blow it out. If it is warm air, the operator adjusts the air flow direction controller and stacks the vent holes of each plate to make them open.
Hot air may be blown out laterally from the vent in this open state. Further, when the hot air or the cold air is simultaneously blown out in the horizontal direction and the vertical direction along the side wall, it can be easily performed by the operator adjusting the air flow direction adjuster, as described above.

As described in claims 4, 5 and 6, the first plate and the second plate have substantially the same plane shape in a substantially circular shape, and the first plate and the second plate have the same vent hole. If it has an opening shape, it is possible to prepare two substantially circular first plates that have vent holes opened by punching, etc., and use each as the first plate and the second plate, which enables mass production of air flow direction controllers. It ’s easy and cheap,
It has a simple and inexpensive blowout structure for air conditioning. Further, if the vents having the same opening are opened in an arc shape having different diameters as described in claims 7, 8 and 9, the first plate or the second plate
By rotating the plate or both the first plate and the second plate, the opening area of the vent hole can be continuously adjusted, and continuous air volume adjustment can be performed. Also, the first or second
The warm air or cold air that hits the closed portion formed by the plate and any non-opening portion is blown from the closed portion side through the outer peripheral blowing space in a substantially constant direction.
If the plate and the second plate are respectively rotatable, the first plate and the second plate can be rotated without shifting the phase of the airflow direction controller whose rotation has been adjusted in that state, and the ventilation port It is possible to easily change the blowing direction of warm air or cold air blown from the outer circumferential blowing space to a predetermined direction without changing the air flow direction.

According to the thirteenth, fourteenth, and fifteenth aspects, the first plate and the second plate have substantially the same planar shape in a plan view, and the left half surface region and the right half surface region are alternately formed into a substantially semicircular arc shape. If you have both vent holes that are opened, you can prepare two substantially circular first plates that have vent holes opened by punching, etc., and use each as the first plate and the second plate. Mass production of the regulator is easy and cheap, and further, some patterns of the first plates having different diameters are manufactured in advance, and some of the pre-manufactured first plates must be combined. For example, if the first plate, which is slightly larger than the diameter of the ventilation passage, is cut through the connecting portion between the adjacent substantially semi-circular ventilation openings according to the diameter of the ventilation passage, the diameter of the ventilation passage will be reduced. Shape the first plate that fits If two of these first plates are prepared and used as the first plate and the second plate, respectively, and are rotatably connected, an air flow direction adjuster suitable for the diameter of the ventilation passage can be obtained. Can be provided.
In this way, the optimum air flow direction controller can be easily attached to ventilation passages having different diameters, and an inexpensive air-conditioning blowing structure can be obtained. In this air-conditioning blowout structure, if the ventilation port is opened, the ventilation port is opened on the entire surface of the air flow direction controller, and the first plate or the second plate or the second plate is closed so as to close the ventilation port in this opening state. If both the 1st plate and the 2nd plate are rotated and adjusted, the vent hole in the open state will be closed in a fan shape around the center point from the boundary between the left half surface and the right half surface. Since the ventilation hole is completely closed with a long rotation distance, it is possible to easily adjust the opening area to a predetermined opening area. Further, at the position where the ventilation port is closed, a non-opening portion and a non-opening portion of the opposing plate that closes the ventilation port form a fan-shaped closing portion, and hot air or cold air hitting this closing portion is directed toward the closing portion. The air flow direction controller guides the air to the outer peripheral blowing space, and blows out a larger amount of hot air or cold air from the outer peripheral blowing space near the closed portion. Similarly to the previous time, if both the first plate and the second plate are rotatable, the first plate and the second plate are rotated together without changing the phase of the first plate and the second plate, and the predetermined plate is rotated. By directing the closed part of the air flow direction controller in the blowing direction, hot air or cold air can be blown in a predetermined direction. The air flow direction controller
It is provided so as to project from the air blow surface of the ventilation passage or a predetermined distance from the air blow surface.

It is an example of a blow-out structure for air conditioning. When hot air is blown from the air outlet 13 to perform air conditioning, an operator manually rotates the first plate 2 to move the vent 3 of the first plate 5 to the second position.
If they are superposed on the ventilation holes 6 of the plate 5 without being displaced, the ventilation holes 3 and 6 will be in a fully opened state on the entire surface of the air flow direction controller 1, and the warm air sent from the air conditioning duct 10 will not be discharged from the outer peripheral blowing space 8 but the ventilation holes 3 and 6.
