[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a reach-distance control type outlet which is installed on a ceiling surface, a wall surface, or the like and automatically controls the reach distance of blown conditioned air.

[0002]

[Prior art]

 Conventionally, air outlets have been provided on the ceiling surface, wall surfaces, etc. in order to achieve air conditioning of the entire room in a building or a predetermined place, and air conditioning is performed while blowing conditioned air from the air passages of the air outlets to the indoor side. It is intended to. At this time, there is a temperature difference between the temperature of the conditioned air blown out from the air outlet and the indoor temperature particularly in summer and winter when the temperature is clear. Therefore, the warm air that is blown out in the winter tends to rise naturally, so only the ceiling is heated, and it is difficult to adequately air-condition people on the floor inside the room, and the cool air in the summer tends to fall naturally. Therefore, it is preferable that the air conditioning is performed by naturally descending from the air outlet.

From such a point of view, for example, a slot nozzle type outlet is proposed in Utility Model Registration Application No. 192576 (Showa 59-106860) in 1984. There, as shown in FIG. 12, two blades opposed to each other in the longitudinal direction in the flow path of the air outlet are pivotally attached and hung down, and the two opposed blades are linked by an elastic member. ing. When the warm air is blown out in the winter season, the elastic members are contracted to squeeze the lower ends of the blades toward the inner surface to accelerate the wind velocity in the flow path to extend the reach of the warm air to be blown out and cool the summer air. At the time of blowing, the expansion member is expanded to widen the mutual interval of the blade members to reduce the wind velocity in the flow passage, and the arrival distance of cold air is controlled to be short.

[0004]

[Problems to be solved by the device]

 However, in the slot nozzle type outlet, since there is a space from the lower end of the blade body to the lower end of the outlet body, the airflow is diffused and the reach distance cannot be changed efficiently, Also, since two shafts are provided in the flow path and the expandable member is linked to the lower end sides of the two blade bodies pivotally hung on the two shafts, the assembly of the blade body in the flow path is performed. However, there is a problem that the interval setting is complicated, the number of parts is increased, and the manufacturing cost is easily increased.

The present invention has been made in view of the above conventional problems, and an object thereof is to axially support a single blade body in a flow path of an outlet and to move the blade body in an arbitrary direction. By extending the reach of warm air in winter while controlling the reach of cool air in summer while turning, the structure is simple, the assembly of blades, the number of parts is small, and the manufacturing cost is low. It is to provide a reach control type air outlet that can be saved.

【Example】

 Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 to FIG. 6 show a reach control air outlet 10 according to a first embodiment of the present invention. As is clear from the figure, the reach-distance control type air outlet 10 has a required width and is provided with a flow passage 12 through which air flows and from a center portion in the width direction of the flow passage 12. And a blade body 16 rotatably supported at a position biased to the flow path wall 14 on the side.

As shown in FIGS. 1 and 2, the flow path 12 is made of, for example, a metal, a light metal, a hard synthetic resin, or the like, and has a main body frame formed in a rectangular tubular shape from the upper end opening to the lower end opening. The main body frame 18 is provided with a frame portion 20 that is fitted and connected to the peripheral edge of the lower end of the body frame 18. The main body frame 18 is not necessarily limited to the rectangular tubular shape, but may be a rectangular or polygonal tubular shape. Reinforcing frames 22 and 22 fixed to both ends in the longitudinal direction of the frame portion 20 are juxtaposed along the lower end of the main body frame 18, and are connected to the lower surfaces of the reinforcing frames 22 and 22. A plurality of fixed blades 24 are provided. Further, inverted U-shaped mounting plates 26, 26 are provided on the frame portion 20 so as to project above the reinforcing frames 22, 22, and the mounting screws 28 are mounted from the reinforcing frames 22, 22 to the mounting plates 26, 26. , 28 are projected.

A feature of the present invention is that one blade is rotatably pivotally supported at a position biased from a central portion in the width direction in the flow path of the outlet to a flow path wall on either side. When a blade is provided and one end of the blade comes into contact with the flow path wall while rotating the blade, a flow of a width narrower than the width of the flow path is formed between the other end of the blade and the other flow path wall. It is to control the reaching distance of the conditioned air blown out while forming a path so that the warm air reaches a long distance and the cool air reaches a short distance.

As shown in FIGS. 2 and 3, the vane body 16 is provided in a rectangular plate 30 fitted and arranged in the longitudinal direction in the main body frame 18, and at a substantially vertical center position of the rectangular plate 30. 3, the vane body 16 is disposed at a position deviated from the central portion in the width direction of the flow passage 12 of the main body frame 18 to one flow passage wall 14, as shown in FIG. Both ends of the rotary shaft 32 are rotatably supported by both side walls 34, 34 of the main body frame 18 shown in FIG.

In the standing state of the blade body 16 in parallel with the one flow path wall 14 of the main body frame 18, as shown by the solid line in FIG. 3, the upper right side surface of the blade body 16 protrudes from one side wall 36. The blade 38 is stopped by the stopper 38 provided, and the lower left side surface of the blade body 16 is brought into contact with the lower fixed blade 24. When the blade body 16 in this standing state tilts counterclockwise in FIG. 3 and the upper end of the blade body 16 abuts the flow path wall 14 as shown by the phantom line, the lower end portion of the blade body 16 is in contact. With the other flow path wall 14, the flow path 12 is narrowly formed into a narrow flow path.

As shown in FIG. 5, the blade body 16 has the upper right side surface of the blade body 16 engaged with the stopper 38 in the upright state, and the lower end of the blade body 16 has the upper end of the fixed blade 24. You may arrange so that it may adjoin. In this state, when the blade body 16 is tilted counterclockwise as shown by the imaginary line, the gap between the lower end of the blade body 16 and the upper end of the fixed blade 16 becomes slightly wider than in the state of FIG. Does not affect the accelerating state of the flowing air.

Thus, in the standing state of the blade body 16, the flow passage width H in the flow passage 12 is not narrowed by the blade body 16, and the air flowing in the flow passage 12 blows while flowing at a constant speed. Will be issued. Further, in the tilted state of the blade body 16, the inside of the flow passage 12 is narrowed by the lower end portion of the blade body 16, so that the air flowing through the inside of the flow passage 12 is accelerated, and the air blown out is the blade body. The reachable distance is longer than that of the 16 standing states. The rotating operation of the blade body 16 may be performed manually by setting a rotating portion so that the blade body 16 cannot be rotated unless a required drive torque is applied, or it may be operated manually. Alternatively, it may be rotated by driving a motor.

In the present embodiment, the blade body 16 is rotated by the balance of the bias between the biasing member and the shape memory member. That is, as shown in FIGS. 1, 2, and 3, the rotation control of the blade body 16 from the standing state along the flow path 12 to the inclined state in which the upper end portion of the blade body 16 contacts the flow path wall 14 is performed. Therefore, a biasing spring 40 and a coil spring 42 made of a shape memory alloy are stretched on the blade body 16 and the flow channel wall 14 on the opposite side of the flow channel wall 14 with which the upper end of the blade body 16 abuts. There is.

A U-shaped locking plate 44 that intersects with the rotary shaft 32 is fixed at a substantially central position of the blade body 16, and a locking plate 44 of the blade body 16 is fixed to the flow path wall 14. The U-shaped locking plates 44 are fixed so as to face each other. The coil spring 42 is stretched from the lower end side of the locking plate 44 of the vane body 16 to the upper end side of the locking plate 44 of the flow channel wall 14, and from the upper end side of the locking plate 44 of the vane body 16 to the flow channel wall. The biasing spring 40 is stretched around the lower end side of the locking plate 44 of 14.

The transformation temperature of the coil spring 42 made of the shape memory alloy is set to about 26 ° C. For example, as shown in FIG. 7, the air flowing through the flow passage 12 in the main body frame 18 is warmed up. When the temperature becomes W and the temperature rises to about 26 ° C. or more, the coil spring 42 transforms and contracts and the blade body 16 tilts while resisting the urging force of the urging spring 40, and the upper end of the coil spring 42 moves to the flow path wall 14. Abut. The inside of the flow path 12 is narrowed to a narrow width H1 by the lower end of the tilted blade body 16, and the warm air W flowing through the flow path 12 flows along the tilted blade body 16 and has a narrow width H1. The reaching distance of the warm air W which is accelerated and blown out at the position is extended.

Further, when the temperature of the air flowing through the flow path 12 is about 20 ° C., which is lower than the transformation temperature of the coil spring 42, which is 26 ° C., the coil spring 42 begins to expand while returning to the memory shape and transforming. As shown in the drawing, when the air flowing through the flow path 12 becomes the cold air C and is about 17 ° C. or less, the blade body 16 is rotated by the urging force of the urging spring 40 to be in the standing state and the blade body 16 is erected. Is stopped by abutting against the stopper 38. The standing vane 16 widens the inside of the flow passage 12 to a wide width H2, and the cold air C flowing through the widened flow passage 12 reaches the blown-out cool air C without its speed being accelerated. The distance becomes shorter.

The operation of the reach-controlled air outlet 10 according to the first embodiment of the present invention will be described below. For example, as shown in FIG. 11, the reaching distance control type outlet 10 is configured such that the main body frame 18 is inserted into the space above the ceiling by inserting the main body frame 18 into the space above the ceiling plate 46 in a room or the like. The mounting screws 28 and 28, which are brought into close contact with each other and project upward from the reinforcing frames 22 and 22 shown in FIG. The body frame 18 is connected to a duct or an outlet that communicates with an air conditioning chamber or the like.

In the winter, the warm air W heated to approximately 26 ° C. or more is blown into the main body frame 18 and blows out from the gap between the fixed blades 24 of the frame portion 22, and in the summer, it is approximately 20. The cooling air C cooled to below ℃ is blown out and blown out.

When the warm air W is blown out, the coil spring 42 made of a shape memory alloy provided in the flow path 12 in the body frame 18 transforms and contracts while resisting the urging force of the urging spring 40, and the blade body 16 tilts. Then, the upper end abuts the flow path wall 14, the inside of the flow path 12 is narrowed to a narrow width H1, and the warm air W flowing through the flow path 12 is accelerated, and the warm air W is separated from the ceiling plate 46 to a far point. Efficiently heat the room while extending the reach.

When the cool air C is blown out, the coil spring 42 made of a shape memory alloy is transformed back to the memory shape, and the blade body 16 is rotated by the urging force of the urging spring 40 in a standing state parallel to the flow path 12. The cold air C that moves and is stopped by contact with the stopper 38, and the flow passage 12 is widened to a wide width H2 by the standing blade body 16 and flows through the cool air C without being accelerated. C reaches a perigee close to the ceiling plate 46, and the reaching distance is shortened, and the cool air C cools the room while naturally descending into the room.

In this way, one vane plate 16 is pivotally supported in the main body frame 12, and the vane plate 16 is rotated while maintaining the biasing balance between the biasing spring 40 and the coil spring 42 made of a shape memory alloy. It is possible to control the reaching distance of the conditioned air while moving it. Then, the blade body 16 is axially supported in the main body frame 18 of the flow channel 12, and a biasing spring 40 and a shape memory alloy coil spring 42 are stretched between the blade body 16 and one flow channel wall 14. It has a simple structure, requires no labor for assembling, has a small number of parts, and has a low manufacturing cost.

Next, FIG. 9 and FIG. 10 show a reach control type air outlet 10 according to a second embodiment of the present invention. In this embodiment, the same members as those in the previous embodiment are designated by the same reference numerals, and detailed description thereof will be omitted. The reaching distance control type air outlet 10 of the present embodiment has a required width and a passage 12 through which air flows, and a central portion in the width direction in the passage 12 as in the previous embodiment. And a blade body 16 rotatably provided.

As shown in the drawing, the flow path 12 is formed from a rectangular tubular main body frame 18 from the upper end opening to the lower end opening, and a frame portion 20 is continuously connected to the lower end peripheral edge of the main body frame 18. Has been. Inside the frame portion 20, a plurality of fixed blades 24 are provided in parallel along the lower end of the main body frame 18.

The vane body 16 is formed of a rectangular plate 30 fitted in the longitudinal direction of the main body frame 18, and the rectangular plate 30 has a main frame 12 of the flow path 12 whose eccentric position in the width direction is near the lower end. Is attached to a rotary shaft 32 that is axially supported at a substantially central position in the width direction. Further, the width direction length L 1 of the blade half portion on the longer width side of the rotation axis 32 of the rectangular plate 30 is formed to be longer than half the length of the flow passage width H of the flow passage 12.

As a result, as shown in FIG. 9, when the blade body 16 tilts to one of the flow channel walls 14 of the flow channel 12, the upper end portion of the blade body 14 contacts the flow channel wall 14 in an inclined manner. Contacted. As shown in FIG. 10, when the blade body 16 is in the upright state, the stopper 38 abuts on the right side surface on the upper end side of the blade body 16 and the left side surface on the lower end side abuts on the fixed blade 24 to be stopped. . The lower end side of the blade body 16 may be arranged in contact with the fixed blade 24 as shown in FIG.

As shown in FIGS. 9 and 10, the blade body 16 is rotationally controlled from a standing state along the flow channel 12 to an inclined state in which the upper end of the blade body 16 is in contact with the flow channel wall 14. Therefore, a bias spring 40 and a coil spring 42 made of a shape memory alloy are stretched on the blade body 16 and the flow channel wall 14 on the opposite side of the flow channel wall 14 with which the upper end of the blade body 16 abuts. .

The coil spring 42 is stretched from the lower end side of the locking plate 44 fixed to intersect with the rotary shaft 34 of the blade body 16 to the upper end side of the locking plate 44 fixed to the flow path wall 14. The biasing spring 40 is stretched from the upper end side of the locking plate 44 of the blade body 16 to the lower end side of the locking plate 44 of the flow path wall 14.

Also in the reach-controlled air outlet 10 of the second embodiment, as shown in FIG. 10, the main body frame 18 is inserted into the space above the ceiling and installed in the insertion opening opened in the ceiling plate 46 in the room or the like. Then, a duct extending from the air conditioning chamber or the like installed in the space above the ceiling is connected to the main body frame 18.

The transformation temperature of the coil spring 42 made of the shape memory alloy is set to about 26 ° C. In the winter, the warm air W heated to approximately 26 ° C. or more is blown into the main body frame 18 and the frame portion is blown. It blows out from the gap between the fixed blades 22 of 22 and blows out the cool air C cooled to about 20 ° C. or less in the summer.

As shown in FIG. 9, when the warm air W heated to approximately 26 ° C. or more is blown into the flow path 12, the coil spring 42 made of a shape memory alloy provided in the flow path 12 causes the bias spring 40. The blade body 16 tilts and its upper end abuts against the flow path wall 14, while the lower end portion of the flow path 12 is narrowed to the narrow width H1 while resisting the biasing force of The warm air W flowing therethrough is accelerated, and the reaching distance of the warm air W can be extended to a far point separated from the ceiling plate 46.

Further, as shown in FIG. 10, when the temperature of the air flowing through the flow path 12 is about 20 ° C., which is lower than the transformation temperature of the coil spring 42, which is 26 ° C., the coil spring 42 expands while returning to the memory shape and transforming. First, when the air flowing through the flow path 12 becomes the cool air C and the temperature is about 17 ° C. or less, the blade body 16 is erected by the urging force of the urging spring 40 and the blade body 16 contacts the stopper 38. Be restrained. The standing blades 16 do not restrict the lower end of the flow passage 12 in the flow passage 12, but the flow passages on both sides of the lower end of the blade body 14 are widened to a wide width H2, and the cold air C flowing therethrough has its speed. The cold air C that is blown out is reduced in reaching distance while reaching a perigee close to the ceiling plate 46 without being accelerated.

In the second embodiment as well, the rotating operation of the blade body 16 is performed by manually setting the rotating portion so that the blade body 16 cannot be rotated unless a required drive torque is applied. Alternatively, the motor may be driven to rotate in conjunction with the temperature sensor.

Therefore, also in the reaching distance control type outlet 10 of the second embodiment, one vane plate 16 is pivotally supported in the main body frame 12 and the vane plate 16 is formed from the biasing spring 40 and the shape memory alloy. It is possible to improve the air conditioning efficiency by automatically controlling the reaching distance of the conditioned air while automatically rotating while maintaining the bias balance with the coil spring 42. Also, with a simple structure, no labor is required for assembly, The number of points is small and the manufacturing cost is low. In addition, in the first and second embodiments, the shape memory member 42 is not limited to the shape memory alloy, and may be a synthetic resin having a shape memory action or other metal, and the mode is also limited to the coil spring. Alternatively, other shapes such as a leaf spring may be used.
