[Technical field to which the invention belongs]

 The present invention relates to a line-type outlet that is arranged on a ceiling in a space to be air-conditioned and that can adjust the direction in which the air-conditioning gas is blown into this space.

[0002]

[Prior art]

 In the air conditioning equipment, there is a conventional line type outlet that blows out air conditioning gas sent through a duct into a room, which is disclosed in Japanese Utility Model Publication No. 7-31075, which is shown in FIGS. 5 and 6. Shown in. FIG. 5 is a cross-sectional view of a main part of a conventional line-type air outlet, and FIG. 6 is an explanatory view of a conventional line-type air outlet.

In each of the drawings, the conventional line-type outlet 100 is arranged in the ceiling 50, is connected to an air conditioner, a blower, etc. (not shown), is supplied with air for air conditioning, and is blown out indoors. A chamber 101 having an opening formed on the side, a frame member 102 arranged at the opening of the chamber 101, and a swingable member arranged inside the opening region of the frame member 102 about the same axis. The first blade 103 and the second blade 104, and a support shaft 105 that is disposed inside the longitudinal end of the frame member 102 and that supports the first blade 103 and the second blade 104 are provided. .

The first blade 103 and the second blade 104 are bent in opposite directions to each other. Further, a cylindrical portion 103a forming a support hole 103b is provided at the base of the first blade 103, and when the support shaft 105 is fitted, it can be fixed at a predetermined swing position and the support shaft 105 outer diameter and support The fitting degree of the inner diameter of the hole 103b is set. The second blade 104 is swingable by mounting a C-shaped support portion 104a on the outer circumference of the cylindrical portion 103a of the first blade 103. Then, by adjusting the degree of fitting between the inner diameter of the support portion 104a of the second blade 104 and the outer diameter of the cylindrical portion 103a of the first blade 103, an appropriate frictional force is generated, and this frictional force causes the second blade 104 to move to a predetermined level. Can be fixed in position.

When changing the blowing pattern of the air-conditioning air, by fixing the first blade 103 and the second blade 104 at an arbitrary position in the middle of the closed state and the open state, the direction of the air flow and the air flow can be arbitrarily set. Can be set. In the case of cooling, the first blade 103 and the second blade 104 are held in a state of being brought close to either the inner wall side of the frame member 102, and the first blade 103 or the second blade 104 is held inside the frame member 102. The cool air, which is guided by the ventilation passage only beside one of the blades, is blown out to either the left or right side so that the cool air, which is heavier than the room air, is dispersed inside the room along the ceiling. In the case of heating, the first blade and the second blade are separated from the inside of the frame member 102, the ventilation path is set to the side of both blades so that the blowing direction is downward, and the first blade 103 and the second blade 104 are With a large opening angle, the ventilation passage is narrowed, and the warm air is blown out at a high speed so that a slight amount of warm air can reach the lower part of the room to warm the entire room.

[0006]

[Problems to be solved by the device]

 Since the conventional line-type air outlet is configured as described above, even when the first blade 103 and the second blade 104 are directly moved by inserting a finger through the opening on the air outlet side when changing the air outlet pattern, When the tips of the first blade 103 and the second blade 104 are tightly closed, the fingers cannot be hung on the respective blades and the individual blades cannot be moved individually. For example, it is necessary to arrange an operation dial or the like integrally with each blade at both ends of the frame member 102 in the longitudinal direction and adjust each blade by moving the blade, which makes the structure complicated and increases the cost. In addition, there was a problem that workability was poor.

Further, the edge portion of the frame member 102 is arranged in a direction in which it is resistant to the air flow blown out, and due to its shape, the air flow blown out in the lateral direction is disturbed and a predetermined air blow direction can be maintained. In addition, there were problems such as wind noise and increased pressure loss.

The present invention has been made to solve the above-mentioned problems, and it is easy to directly operate the blade from the outlet opening, and the position of the blade can be easily moved to change the outlet pattern. It is an object of the present invention to provide a line-type air outlet in which the number of parts can be reduced and the cost can be reduced, and the airflow can smoothly flow even if the air outlet pattern is changed.

[0009]

[Means for Solving the Problems]

 The line-type outlet according to the present invention is provided with an air-conditioning gas, and has an elongated rectangular outlet opening for blowing the gas into a space to be air-conditioned, and an outlet main body. It is equipped with a plurality of blades that are positionally adjustable in the longitudinal direction of the inside and that guides the direction in which the gas blows out in a predetermined direction. In the line-type outlet that blows out to, the blade is formed as a substantially plate-shaped body having a curved cross-sectional shape, and the curved concave portion is opposed to the inside of the outlet main body in parallel to the longitudinal direction of the outlet opening. In this state, the two blades are arranged facing each other, and are supported by the air outlet main body at both ends in the longitudinal direction of the plate body so as to be swingable, and hold the two blades in predetermined directions. Equipped with two blades Wing tip of the opening portion side in a state where most close from each other by moving are those facing a predetermined gap or indentation. As described above, in the present invention, even when the two blades are closed to each other, a gap is created at the tips of the blades facing each other, so that the operator directly moves the blades away from each other (toward the opening side). It can be operated directly, and the direction of the blade can be changed from the outlet opening side to change the outlet pattern for all blade positions, improving workability and eliminating the need for separate operating means. The number of parts can be reduced, the structure can be simplified, and the cost can be reduced.

In addition, the line-type outlet according to the present invention is provided with an operation protrusion that protrudes from the curved inner surfaces of the two blades facing each other, if necessary. The blade is adjusted so as to be swingable. As described above, according to the present invention, since the operation protrusion is provided inside the curved portion of each blade, the blade can be operated with a fingertip or the like when the blade is moved to the closing side, which is excellent in operability and allows the blade to be adjusted. The property is improved. In addition, the operating protrusion plays the role of a rib to increase the strength of the blade and reduce the shaking and vibration caused by the air flow.

In addition, in the line-type outlet according to the present invention, the opposed operating protrusions are arranged at different protruding positions on the facing blades as necessary, and the positions of the operating protrusions are different from each other. The relationship is staggered. As described above, according to the present invention, the operating protrusions are arranged in a staggered manner so as not to interfere with the other operating protrusion, and are formed in a larger shape correspondingly, so that the blade is moved when it is moved to the closing side. Is easier to perform, and the workability of adjusting the blades is further improved. In addition, the operating projection plays the role of a rib, greatly increasing the strength of the wing and reducing the shaking and vibration caused by the air flow.

Further, the line-type outlet according to the present invention is formed by bending the peripheral edge of the outlet opening portion of the outlet main body toward the inside of the opening by a predetermined angle, if necessary. As described above, in the present invention, by forming the edge portion of the blowout opening at a predetermined angle, the flow of the blown airflow can be made smooth, pressure loss can be reduced to improve efficiency, and wind noise etc. can be reduced. Noise is reduced.

[Embodiment of the invention]

 (One Embodiment of the Present Invention) A line type outlet according to one embodiment of the present invention will be described below with reference to FIGS. FIG. 1 is a perspective view of a line-type outlet according to the present embodiment, FIG. 2 is a vertical cross-sectional view of a schematic configuration of the line-type outlet according to the present embodiment, and FIG. 3 is a line-type according to the present embodiment. FIG. 4 is an explanatory view of the opening / closing state of the main part of the air outlet, and FIG. 4 is an explanatory view of the main part wind direction adjustment state of the line-type air outlet according to the present embodiment.

As shown in each of the drawings, the line-type outlet 1 according to the present embodiment is provided with a cylindrical neck portion 11a and an outlet opening portion 11b formed in an elongated rectangular shape on the indoor outlet side. The outlet body 11, the first blade 12 and the second blade 13 that are swingably disposed in the opening area of the outlet body 11, and a predetermined length from the inside of the outlet body 11 to the opening area. And a support shaft 14 for holding each blade.

The outlet main body 11 is formed as a hollow housing by assembling a plurality of glass boards of heat insulating material, and a neck portion 11a for connecting the air conditioning duct 51 is disposed on one of two opposing side walls. An outlet opening 11b is formed in an elongated rectangular shape at the lower end on the indoor outlet side, and an airflow guide portion 11c bent at a predetermined angle is formed at the lower edge of the outlet opening 11b. In the ceiling 50, the air-conditioning duct 51 is connected to take in the air-conditioning air and blow it out into the room through the blow-out opening 11b.

The first blade 12 and the second blade 13 are arranged in the air outlet body 11 near the air outlet opening 11 b, and the longitudinal ends of the air inlet side end portions are swingable by the support shafts 14. It is a structure that is supported by a shaft and is formed into a plate-like body having a curved cross-section in which the blow-out side tip portions face each other. At the end of the first blade 12 on the air inlet side, a cylindrical portion 12a forming a support hole 12b is provided as a holding means, and when the support shaft 14 protruding from the inside of the outlet body 11 is fitted, a predetermined swinging motion occurs. The fitting degree between the outer diameter of the support shaft 14 and the inner diameter of the support hole 12b is set so that the first blade 12 can be fixed at the position. The second blade 13 is formed with a C-shaped support portion 13a, which is mounted around the outer periphery of the cylindrical portion 12a of the first blade 12, at the end portion on the air inlet side as a holding means, and the support portion 13a of the second blade 13 is formed. By adjusting the fitting degree between the inner diameter and the outer diameter of the cylindrical portion 12a of the first blade 12, an appropriate frictional force is generated, and the frictional force allows the second blade 13 to be fixed at a predetermined swing position. Operation protrusions 12c and 13b are formed so as to project on the curved inner side surfaces of the two blades facing each other. The projecting positions of the operating projections 12c and 13b of the first blade 12 and the second blade 13 are staggered so that they do not interfere with each other in the closed state, and the projection height is increased accordingly. To make it easier to operate. In addition, the tip ends of the first blade 12 and the second blade 13 are formed by bending them so as to face each other toward the curved inner side in a hook-shaped cross section, and when the two blades are closed, they can be operated by inserting fingers. The tip concave portion 15 is formed.

Next, the blow-out pattern adjusting operation in the line-type blow-out port based on the above configuration will be described. When changing the blowing pattern of the air-conditioning air, the blades 12 and 13 are directly moved from the blowing opening portion 11b to the left or right to be held at a predetermined swing position. When the first blade 12 and the second blade 13 are separated from each other so that the front ends of the blades 12 and 13 are completely brought into contact with the inner wall of the outlet main body 11, the air passage is closed and the air passage is blocked. The blowing is stopped (see FIG. 3 (A)). Conversely, when the first blade 12 and the second blade 13 are placed in the open state by moving them away from the inner wall of the outlet main body 11 and bringing them close to each other, the airflow flows along the outer circumferences of both blades and blows downward. (See FIG. 3B). If the first blade 12 and the second blade 13 are slightly separated from this state so as to be close to the inner wall of the outlet main body 11, the air passage is narrowed and the air flow velocity is increased when the air volume is reduced. Further, when the first blade 12 and the second blade 13 are swung to either side of the inner wall and brought close to each other, the airflow flows along the outer curved surface of either one of the left and right horizontal directions. The air can be blown toward (see Fig. 4). At this time, if the other blade is brought closer to the blade that is in contact with the inner side wall, the air passage is expanded and the air volume is increased. On the contrary, if it is separated, the air passage is narrowed and the air volume is decreased. As the air flow decreases, the speed of the air flow increases. In addition, even if the tips of the first blade 12 and the second blade 13 come into contact with the inner wall of the outlet main body 11 in the closed state and it becomes difficult for a finger to be caught at these tips, the operation protrusions 12c and 13b on the inside of the curve are not removed. Each wing can be moved by pinching it with a finger. In addition, even if the first blade 12 and the second blade 13 are close to each other in the open state and the tip is closed, move the blades 12 and 13 by inserting a finger into the tip recess 15 formed at the tip. You can

When heating is used, an open state is obtained in which the blades 12 and 13 are brought close to each other by operating directly from the outlet opening 11b to separate the tips of the first blade 12 and the second blade 13 from the inner wall of the outlet body 11. And the blowing direction is downward. In this state, the air volume can be adjusted by moving the first blade 12 and the second blade 13 closer to each other or moving them away from each other to bring them closer to the inner wall of the outlet body 11. The warm air sent from the air conditioning duct 51 enters the neck portion 11a, flows along the blades 12 and 13, and blows downward into the room (see FIG. 3B). At this time, the airflow does not flow along the airflow guide portion 11c and is not disturbed unnecessarily, and the airflow can be smoothly blown out without resistance. Warm air, which is lighter than the air in the room, can be blown downwards from the ceiling 50 to reliably reach the living area. In addition, the warm air attracts air in the room with lower temperature and mixes with it, so The conduction of heat is promoted, the effect of raising the temperature of the indoor air is great, and the room can be warmed in a short time.

On the other hand, when the air conditioner is used, the blower opening 11b is directly operated in the same manner as described above to bring the tip end of the first blade 12 into complete contact with the inner wall of the outlet main body 11, and the second blade 13 is also the first blade 12. When it is moved to the side, the cool air sent from the air conditioning duct 51 enters from the neck portion 11a of the outlet main body 11, and the airflow gradually flows sideways along the outer curved surface of the second blade 13 to the left in the figure. It blows out substantially horizontally toward the room (see FIG. 4 (A)). At this time, the airflow can be smoothly blown sideways along the airflow guide portion 11c without being disturbed. Similarly, when the tip of the second blade 13 is completely brought into contact with the inner wall of the outlet main body 11 and the first blade 12 is brought closer to the second blade 13 side, the air flow is outside the first blade 12. It gradually flows sideways along the curved surface and blows out substantially horizontally toward the right in the figure (see FIG. 4 (B)). Cold air, which is heavier than the air in the room, is blown out substantially horizontally and can be sufficiently diffused into the room from the ceiling 50 to reach the floor surface. In addition, the cool air attracts the air around the ceiling 50, which is relatively warm, and mixes with it. Therefore, the effect of cooling the indoor air is great, and the room can be cooled in a short time. The amount of air can be adjusted by moving the second blade 13 in the leftward direction and the first blade 12 in the rightward direction to the other blade or vice versa.

As described above, in the line-type outlet according to the present embodiment, it is possible to easily adjust the position from the outlet opening 11b regardless of the positions of the first blade 12 and the second blade 13, so that it is optimal. It is possible to easily change to a different blowing pattern, improve work efficiency, and reduce costs by simplifying the structure. Further, the turbulence of the airflow does not occur due to the airflow guide portion 11c, and the airflow can be smoothly blown in a predetermined direction even if the blowing pattern is changed.

In the line-type outlet according to the above-described embodiment, the outlet body 11 is formed by assembling a plurality of glass boards of heat insulating materials, but is made of a steel plate or an electric zinc plated steel plate. Alternatively, it may be made of a steel plate or an electrogalvanized steel plate on which electrostatic flocking is applied.
