BACKGROUND OF THE INVENTION
The present invention is disposed so as to protrude from a ceiling surface or a wall surface or a floor surface facing a space to be air-conditioned, changes a blowing direction of the air-conditioning gas to the air-conditioning target space, and The present invention relates to a blowout device that can appropriately reach a predetermined location in an air conditioning target space.
[0002]
[Prior art]
Among air outlets that blow out conditioned air sent through a duct into an indoor space in an air conditioning facility, as a blowing direction variable type that allows conditioned air to reach an arbitrary location below the indoor space from the ceiling or wall, A nozzle-type air outlet device using a flexible duct has been used. Such a conventional air outlet apparatus is shown in FIG. FIG. 8 is a schematic configuration diagram of a conventional air outlet device.
[0003]
In FIG. 8, the conventional air outlet device 100 is formed of a deformable flexible duct having a predetermined length, and has one end attached to the ceiling (or wall) 50 and is connected to the duct 51 inside the ceiling 50 for harmony. The structure includes an air outlet main body 101 to which air is supplied and an air volume adjusting damper 102 disposed inside the ceiling 50.
In the conventional outlet device 100 having the above-described configuration, the airflow is blown straight out from the opening on the other end side of the outlet body 101 into the room, and the user can directly adjust the other end of the outlet body 101 by hand. The other end of the air outlet body 101 is directed in the direction in which it is desired to be blown. Further, when adjusting the air volume of the airflow to be blown out, the damper 102 for adjusting the air volume is adjusted directly or remotely.
[0004]
[Problems to be solved by the invention]
Since the conventional air outlet device is configured as described above, the air outlet body 101, which is a flexible duct, has elasticity, and even if the other end is moved by hand to change the direction, the air outlet body 101 is slightly closer to the original position. It has returned and had the subject that it was difficult to adjust to a desired direction correctly. In addition, since the entire flexible duct forming the outlet body 101 is deformed in the wind direction adjustment, it is necessary to sufficiently ensure the strength of the outlet body 101 itself and the strength of the ceiling 50 to which the force is applied, which tends to increase the cost. In addition, heat insulation processing such as flocking on the outer peripheral side of the air outlet main body 101 and arrangement of a heat insulating material cannot be performed, and there is a problem that condensation on the surface is likely to occur during cooling.
[0005]
On the other hand, the air volume adjustment is performed by the damper 102 in the ceiling 50, but in order to perform the work directly on the damper 102 for adjustment, maintenance, etc., an inspection that enables the worker to approach the damper 102 in the ceiling 50 is possible. There is a problem that a mouth is required at any place, and the processing for installing the inspection port requires labor and cost.
[0006]
Furthermore, when a plurality of air outlet devices 100 are connected to the duct 51 and the air volume is adjusted by the damper 102 for each air outlet device 100, the air volume balance of each air outlet device 100 with respect to the indoor space is lost. However, there is a problem that it becomes difficult to perform heat load processing on the entire indoor space set in advance.
The present invention has been made in order to solve the above-mentioned problems, and it is possible to easily and efficiently perform blowing toward a predetermined location by reliably changing the air flow blowing direction, and to adjust the air volume with respect to the blowing air flow that can be adjusted in direction. However, it aims at providing the blower outlet apparatus which can maintain the supply air quantity to a blower outlet uniformly, and can prevent the bad influence to other blower outlets.

[0013]
In each of the drawings, the air outlet device 1 according to the present embodiment is formed of a substantially cylindrical body that is open at both ends, and one end side of the substantially cylindrical body is fixed to a ceiling (or wall) 50 to be subject to air conditioning. The air outlet main body 2 that protrudes into the indoor space and is supplied with conditioned air from the one end side, and the air outlet body 2 from the air outlet main body 2 at a circumferential side surface that is a predetermined distance away from one end side of the air outlet main body 2. A substantially cylindrical branch tube 3 that is protruded by a predetermined length and is integrally disposed with the inside thereof communicating with the air outlet body 2, and a cylindrical shaft formed by the substantially cylindrical body. As an air flow guide means disposed in the opening on the other end side of the outlet body 2 such that the direction can be tilted within a predetermined angle range with respect to the cylinder axis direction of the outlet body 2 and can be rotated around the cylinder axis of the outlet body 2. A predetermined position inside the outlet body 2 between the middle nozzle 4 and the branch cylinder 3 and the middle nozzle 4 A damper 5 as an air volume adjusting means for changing the opening area in the outlet body 2 and a branch cylinder opening area in the branch cylinder 3 so as to be openable and closable. When the branch cylinder 3 is closed and the damper 5 reduces the opening area in the outlet body 2, it opens and the airflow flows from the outlet body 2 into the branch cylinder 3 and the airflow from the branch cylinder 3 into the indoor space. And a non-return damper 6 as airflow branching control means for allowing the airflow.
[0014]
The blower outlet body 2 is formed as a T-tube integrated with another cylindrical body projecting in a substantially T-shape at a predetermined position on the peripheral side surface of a predetermined substantially cylindrical body, and a heat insulating material 2a is disposed on the outside. One end is fixed to the ceiling 50 of the indoor space and protrudes downward. One end is connected to a duct 51 inside the ceiling 50 to take in conditioned air, and this conditioned air is opened to the other end. It is the structure which blows out from the interior space. In addition, a cylindrical body having a diameter inscribed inside the branch portion of the T-shaped tube is partly protruded into the outlet body 2 so as to be integrated with the branch portion of the T-shaped tube. In the branch cylinder 3, a hinge part 3a for supporting the non-return damper 6 in a tiltable manner is disposed. Further, on the inner periphery of the other end side of the air outlet body 2, a rotating cylinder 2 b formed of a cylindrical body having a diameter inscribed inside the air outlet body 2 is configured to be rotatable around the tube axis of the air outlet body 2. It is a configuration to be held.
[0015]
The middle nozzle 4 is formed of a cylindrical body having a diameter smaller than that of the rotating cylinder 2b, and is supported on the inner side of the rotating cylinder 2b so as to be tiltable about an axis orthogonal to the cylinder axis direction of the outlet body 2. In addition to the fact that the rotation position can be adjusted by moving the rotating cylinder 2b with respect to the outlet body 2, the opening direction of the middle nozzle 4 can be adjusted in an arbitrary direction below the other end of the outlet body 2. It is said. This middle nozzle 4 is a mechanism that guides the airflow passing through the outlet body 2 in the direction of the cylinder axis of the middle nozzle 4 and blows it out into the indoor space.
[0016]
The damper 5 is formed of a circular plate-like body capable of closing the inside of the air outlet body 2, is disposed on the air outlet body 2 so as to be tiltable within a predetermined angle range, and is provided on the outside of the air outlet body 2. It is the structure by which a tilt angle is adjusted from the blower outlet main body 2 outer side.
The non-return damper 6 is formed of a substantially circular plate-like body along the inner peripheral surface of the branch cylinder 3, and a predetermined portion is fixed to the hinge portion 3 a of the branch cylinder 3 to be inside the branch cylinder 3 at a predetermined angle. It is the structure which is arrange | positioned freely in the range tilt and controls the passage of the airflow in the branch cylinder 3. This non-return damper 6 opens on the tip side of the branch cylinder 3 but does not open on the side close to the outlet body 2. The branch cylinder 3 around the check damper 6 protrudes into the outlet body 2 by a predetermined length, so that the pressure in the branch cylinder 3 upstream of the check damper 6 when the damper 5 is fully opened is reduced to the check damper 6. It is possible to prevent the airflow from the outlet body 2 from flowing into the branch cylinder 11 and directly pushing the non-return damper 6 open. When the damper 5 is fully opened, the branch cylinder 3 is closed. The entire air volume can be blown out only from the lower end of the outlet body 2. Since the opening / closing of the non-return damper 6 is controlled only by the pressure change in the air outlet body 2 associated with the adjustment of the air volume of the damper 5, a simple mechanism that is not linked to other adjustment portions can be achieved, and the cost can be reduced.
[0017]
Next, the air flow blowing direction and the air volume adjusting operation in the air outlet device based on the above configuration will be described. The blow direction adjustment is performed by adjusting the rotation position and the inclination angle of the middle nozzle 4 at the lower end of the blow body 2 with respect to the blow body 2 so that the opening of the middle nozzle 4 is directed to a desired location where the air flow is to be sent. The air flow guided to the middle nozzle 4 is blown out in the front direction of the opening of the middle nozzle 4, and the air flow in the desired direction is obtained.
[0018]
On the other hand, the air volume adjustment is performed by adjusting the inclination angle of the damper 5 from the outside of the outlet body 2. When the damper 5 is parallel to the tube axis direction of the air outlet body 2, the airflow that blows out from the lower end of the air outlet body 2 is maximized without giving resistance to the airflow that goes downward in the air outlet body 2. In this maximum air volume state, the pressure upstream of the damper 5 does not increase, so the non-return damper 6 in the branch cylinder 3 does not open, and the airflow smoothly advances only downward through the outlet body 2 to the middle nozzle 4. Guided and blown out in a predetermined direction (see FIG. 4).
[0019]
When the damper 5 is tilted with respect to the tube axis direction of the outlet body 2 and the opening area in the outlet body 2 is narrowed, the amount of air blown from the lower end of the outlet body 2 is reduced and the pressure on the upstream side of the damper 5 is increased. The non-return damper 6 opens due to the pressure difference between the front and the back, and the airflow proceeds downward in the outlet body 2 and also into the branch cylinder 3, and conditioned air is blown into the indoor space from the opening of the branch cylinder 3. (See FIG. 5).
[0020]
Further, in a state in which the damper 5 is at right angles to the cylinder axis direction of the air outlet body 2 and the inside of the air outlet body 2 is closed, the blowout from the lower end of the air outlet body 2 stops, while all the supplied conditioned air is discharged. The conditioned air advances from 2 to the branch cylinder 3 and blows conditioned air into the indoor space only from the opening at the tip of the branch cylinder 3 (see FIG. 6). In any state, the air flow that has been prevented from traveling downward by the damper 5 is blown horizontally from the branch tube 3, and particularly in the case of cold air, in addition to local cooling, it can be efficiently applied to the entire indoor space. Cold air can be distributed and the cooling effect is enhanced.
[0021]
As described above, in the air outlet device according to the present embodiment, the branch cylinder 3 is integrally disposed on the side surface of the air outlet main body 2 protruding from the ceiling 50 into the indoor space, and the check damper 6 is provided inside the branch cylinder 3. The middle nozzle 4 and the damper 5 are respectively disposed in the outlet body 2 so that the direction of the conditioned air can be adjusted by the direction of the middle nozzle 4 and the amount of the blown airflow can be adjusted by the damper 5. When the damper 5 is fully opened, the pressure in the branch cylinder 3 upstream of the check damper 6 is kept sufficiently low so that the check damper 6 is not opened. Since the non-return damper 6 is opened by increasing the pressure of the air flow and the airflow from the branch tube 3 is allowed to be allowed, the conditioned air corresponding to the amount of air blown from the other end side of the outlet body 2 by the damper 5 is restricted. Blow out from the outlet 2 All the supplied conditioned air can be blown into the indoor space, and the air volume adjustment with respect to the air flow blown from the other end of the blower outlet body 2 does not affect the amount of conditioned air supplied to the blower outlet body 2, and the blowing direction and the air volume can be changed. Appropriate adjustment can be performed to efficiently and locally harmonize the air, and the air volume of the entire indoor space can always be balanced based on the initial setting. Further, it is possible to blow out in a desired direction only by adjusting the direction of the middle nozzle 4 at the other end of the outlet body 2, and it is not necessary to move the entire outlet body 2 by adjusting the outlet direction, and it is necessary to strengthen the strength of the ceiling 50. In addition, the heat insulating material 2a can be disposed outside the air outlet body 2 to keep the temperature, and even in the case of cooling, no condensation occurs on the outer surface of the air outlet body 2. Furthermore, the air volume can be adjusted indoors by adjusting the tilt angle of the damper 5 from the outside of the air outlet body 2, and there is no need to provide a separate inspection port.
[0022]
In the air outlet apparatus according to the embodiment, the cylindrical middle nozzle 4 is arranged as the air flow guide means at the other end of the air outlet body 2, but the present invention is not limited thereto. It is formed of one or a plurality of substantially plate-like bodies, and a predetermined tangential direction of the substantially plate-like body can be tilted within a predetermined angle range with respect to the cylinder axis direction of the outlet body 2 and can be rotated around the cylinder axis of the outlet body 2 It is also possible to use a guide vane disposed in the opening at the other end of the outlet body 2. Moreover, although the blower outlet main body 2 and the branch pipe | tube 3 are set as the structure which makes a cylindrical body, respectively, it is good also as a structure made into a cylinder body of other opening cross-sectional shapes, such as a rectangle and a rectangle.
[0023]
Moreover, in the blower outlet apparatus which concerns on the said embodiment, although it has set it as the structure which forms the blower outlet main body 2 and the branch cylinder 3 in the integral fixed state, it is not restricted to this, The branch cylinder 3 connection part of the blower outlet main body 2 As a separate body, the branch cylinder 3 and the outlet body 2 are arranged so as to be rotatable around the cylinder axis with respect to the remaining part, and the air flow blowing direction from the branch cylinder 3 can be adjusted in each horizontal direction. It is possible to perform air conditioning appropriately corresponding to various situations in the indoor space in combination with the blowout from the other end side of the blowout outlet body 2.
[0024]
Moreover, in the blower outlet apparatus which concerns on the said embodiment, although it is set as the structure which attaches the one end side of the blower outlet main body 2 to the ceiling 50, and is arrange | positioned in indoor space, it is not restricted to this, One end side of the blower outlet main body 2 As shown in FIG. 7 as an example, an airflow guide portion that can be moved up and down at the other end side opening portion of the outlet body 2 as an example. 7 is installed, and a lamp 7a and an umbrella 7b are attached to the airflow guide 7 as an indirect lighting fixture. When cold air is supplied, the airflow guide 7 is raised to open the other end side opening of the outlet body 2. An actuator (not shown) with a temperature sensing function is provided to lower the airflow guide 7 when the warm air is supplied and the other end side opening is fully closed. It can also be configured to be used as the air volume adjusting means, and the floor When the cool air is supplied from the air outlet, the cool air is blown out substantially horizontally along the air flow guide portion 7 from the opening on the other end side through the air outlet body 2 (see FIG. 7A), and the cool air is widely distributed in the indoor space. On the other hand, when warm air is supplied, warm air blows out from the two branch cylinders 3 near the floor 60 (see FIG. 7B), and warm air can be efficiently supplied into the room.
