In the annular upper lid 63, a wind guide cylinder 631a having the same diameter as the through hole 631 is extended to a position close to the upper lid 32 of the housing 3 on the axial center CL.

  The disc-like lower lid 64 of the inner cylinder 6 is connected to the housing 3 via a bearing 331 supported by the lower lid 33 of the housing 3 on the axial center CL, and the outer lid 643 is connected to the lower lid 33 of the housing 3 It is horizontally supported via a plurality of door wheels (supports) 332 evenly arranged in the circumferential direction. In addition, in order to close a gap with the outer peripheral portion 633 of the annular upper lid 63 on the outer peripheral side inner surface of the upper lid 32 of the housing 3, each branch duct 4 has a substantially triangular inner member 322 for preventing air leakage. It is mounted corresponding to the side wall 31 to be connected.

(Operation method of the first embodiment)
Next, an operation method of the first embodiment of the present air conditioner will be described with reference to FIGS. As shown in FIG. 2 to FIG. 5, the worker M moves in order while working on a plurality of work areas (S 1 to S 6) distributed in a plane and not on a straight line. The air conditioner 10 quickly blows the conditioned air TK toward the worker M who has moved to each work area from the branch duct 4 directed to each work area.

  For example, when the worker M who has finished the predetermined work in the work area S6 moves from the work area S6 to the next work area S1, a person attached to the tip of the specific branch duct 4 corresponding to the work area S6 The sensor 5 outputs an off signal to move the drive pin 711 of the latching solenoid 71 corresponding to the branch duct 4 upward. Along with that, the stopper pin 72 moves upward. The stopper pin 72 corresponding to the work area S6 moves upward, whereby the engagement between the stopper pin 72 and the locking member 73 is released.

  Next, since the engagement between the stopper pin 72 and the locking member 73 corresponding to the work area S6 is released, the conditioned air TK fed downward from the main duct 2 is formed in a curved shape of the inner cylinder 6 Mainly the radially outer guide wall 61 is pressed by wind pressure, and the inner cylinder 6 rotates in the horizontal direction (the direction of the arrow R shown in FIG. 4) with respect to the housing 3 on the axial center CL.

  In addition, the worker M who has moved from the work area S6 to the work area S1 at the same time as the inner cylinder 6 rotates in the direction of the arrow R is a human feeling attached to the tip of the specific branch duct 4 corresponding to the work area S1. The sensor 5 detects. Then, when the human sensor 5 detects the worker M and outputs an ON signal, the stopper pin 72 corresponding to the work area S1 moves downward.

  Next, the locking member 73 which rotates with the inner cylinder 6 abuts on the tip of the stopper pin 72 corresponding to the work area S1 in which the guide portion 732 has moved downward. The guide portion 732 of the locking member 73 is slightly rotated about the rotation center portion 733 until the stop portion 731 formed at the front end abuts against the stopper pin 72. When the rotation shaft 741 connected to the rotation center 733 rotates, the shock absorbing action of the rotary damper 74R of the shock absorbing member 74 works to reduce the impact force on the inner cylinder 6 and the stopper pin 72. Further, the inner cylinder 6 is stopped at a position where the conditioned air TK is supplied to the specific branch duct 4 corresponding to the work area S1 in which the human sensor 5 detects the worker M.

  By operating as described above, the air conditioner 10 supplies the conditioned air TK, which is fed from the main duct 2 into the housing 3, to the specific branch duct 4 corresponding to the work area S1 where the worker M is present. The inner cylinder 6 can be quickly rotated without power without using a driving device such as a motor so as to meet the purpose of energy saving, and a plurality of work areas (S1 to S6) dispersed in a plane and not on a straight line Conditioned air TK, such as cooling or heating, can be blown quickly to the worker M who has moved to.

And a plurality of branch ducts 4 connected to the side wall portion 31B of the housing 3B, and a human sensor 5 mounted on the front end of each branch duct 4, and the work area where the human sensor 5 detects the worker M ((2) in FIG. 2 is an air conditioner controlled to blow out the conditioned air TK such as cooling or heating from a specific branch duct 4 corresponding to S1. Further, the branch duct 4 is directed obliquely from above to a plurality of work areas (S1 to S6) dispersed in a plane, which are not on a straight line. Moreover, the housing 3B is suspended by the hanger from the ceiling side in the vicinity of the middle part of the plurality of work areas (S1 to S6). The air conditioner 1, the main duct 2, the branch duct 4 and the human detection sensor 5 are the same as those in the first embodiment, so the same reference numerals are given and the description thereof will be omitted in principle.

  Further, as shown in FIG. 2 and FIGS. 7 to 12, the housing 3B is a cylindrical casing formed in a substantially star shape in top view, and the main duct 2 is connected to the upper cover 32B of the housing 3B. A cylindrical main connection flange portion 321B is provided so as to protrude upward. Further, the side wall portion 31B of the housing 3B is formed along the outer edge of the upper lid 32B formed in a substantially star-like shape in a plan view. In the side wall portion 31B, cylindrical connection flange portions 41B connected to the branch duct 4 are formed at equal intervals in the circumferential direction. The center line of each connecting flange portion 41B is directed in substantially the same direction as each side of a regular hexagon in contact with a circle of a predetermined radius centered on the axial center CL of the main duct 2.

  Further, the lower cover 33B of the housing 3B is formed in a regular hexagonal shape protruding outward from the side wall portion 31B. The housing 3B has guide walls 61B and 62B for guiding the conditioned air TK fed from the main duct 2 to the connection flange portion 41B of the branch duct 4, and the housing 3B is hit by the wind pressure that strikes the guide wall 61B of the conditioned air TK. The inner cylinder 6B is formed rotatably in the horizontal direction (the direction of the arrow R shown in FIGS. 7 and 9) on the axis CL. In addition, between the housing 3B and the inner cylinder 6B, the inner cylinder 6B is stopped at a position where the conditioned air TK is supplied to the specific branch duct 4 corresponding to the work area S1 where the human sensor 5 detects the worker M A stopper device 7B is attached. In the lower cover 33B of the housing 3B, a circular hole 333B through which the inner cylinder 6B can pass in the vertical direction is formed.

  Further, the stopper device 7B engages with the plurality of stopper pins 72B fixed to the inner cylinder 6B for each branch duct 4 and the stopper pins 72B mounted on the housing 3B based on the signal from the human sensor 5, etc. And a drive mechanism 75B for moving the locking member 73B up and down. In addition, the drive mechanism 75B is controlled such that the locking member 73B engages only with a specific stopper pin 72B for the branch duct.

  Further, in the drive mechanism 75B, a base plate 33B1 formed detachably on the lower lid 33B of the housing 3B, and an intermediate portion 751B2 are pivotally supported by the base plate 33B1 so that both end portions (751B1, 751B3) can move up and down. And a drive portion 752B fixed to the base plate 33B1 and vertically moving one end 751B1 of the arm member 751B. The driving portion 752B is mounted on a rising flange portion 33B11 of a pedestal plate 33B1 extending outward from the outer edge of the lower lid 33B of the housing 3B, and is disposed at a position separated from the inner cylinder 6B. Further, by removing the base plate 33B1 from the lower cover 33B of the housing 3B, the service of the drive mechanism 75B can be easily performed. At this time, the inner cylinder 6B pivotally supported by the pedestal plate 33B1 can also be taken out from the inside of the housing 3B.

  The driver 752 B is preferably a latching solenoid 752 LB that operates in response to a signal from the human sensor 5. In that case, the drive unit 752B does not detect the state in which the locking member 73B is engaged with the stopper pin 72B for a specific branch duct corresponding to the work area detected by the human sensor 5 and the human sensor 5 does not detect The latch mechanism of the latching solenoid 752 LB can mechanically hold the state in which the locking member 73 B is retracted with respect to the stopper pin 72 B for the branch duct corresponding to the work area. Reed switches 752B2 and 752B3 for detecting the movement of the drive pin 752B1 up and down are attached to the drive portion 752B. Further, a magnet 752B4 for operating the reed switches 752B2 and 752B3 is attached to one end 751B1 of the arm member 751B.

  The locking member 73B is connected to the other end 751B3 of the arm member 751B. The arm member 751B is disposed to separate the middle portion 751B2 left and right, and is formed in a substantially rhombic frame. The middle portion 751B2 separated left and right is connected by a connecting rod 754B, and the connecting rod 754B is pivotally supported by left and right bearing portions 753B fixed to the base plate 33B1. In addition, since the arm member 751B is pivotally supported by the left and right bearing portions 753B, it is possible to prevent the arm member 751B from tilting against a horizontal impact when the locking member 73B and the stopper pin 72B are engaged.

  In addition, the locking member 73B is formed of a hook-shaped locking claw that rotates in the horizontal direction. The plurality of locking claws 73TB may be provided so as to radially extend from the rotation center portion 733B, and the number of the locking claws 73TB is not necessarily limited to four.

And a stopper 731B protruding inward from the tip of the guide 732B. A gap through which the stopper pin 72B passes is formed between the stopping portion 731B and the adjacent guide portion 732B. The stopper pin 72B abuts on the middle portion of the guide portion 732B, moves to the stop portion 731B while in sliding contact with the guide portion 732B, and is engaged by the stop portion 731B. At this time, the locking member 73B rotates in the horizontal direction (the direction of the arrow Q) about the rotation center portion 733B. A through hole 33B12 through which the locking member 73B can pass is formed in the base plate 33B1.

The buffer member 74B is preferably a rotary damper 74RB in which the rotation shaft portion 741B is connected to the rotation center portion 733B of the locking member 73B. In this case, when the stopper pin 72B abuts on the locking member 73B, the damper mechanism of the rotary damper 74RB acts to stop the rotation of the inner cylinder 6B while decelerating gradually. The buffer member 74B may be a power generation motor 74HB in which the rotation shaft portion 741B is connected to the rotation center portion 733B of the locking member 73B. In this case, when the stopper pin 72B abuts on the locking member 73B, the magnetic repulsive force of the power generation motor 74HB acts, and the power generation motor 74HB generates power while gradually decelerating the rotation of the inner cylinder 6B. Can be supplied to the stopper device 7B.

  In addition, the inner cylinder 6B is connected to the guide walls 61B and 62B and the upper ends of the guide walls 61B and 62B and is a circle in which a through hole 631B having substantially the same inner diameter as the main duct 2 is drilled on the axial center CL of the main duct 2.

The guide walls 61B and 62B have a predetermined width (for example, corresponding to the inner diameter of the branch duct 4) from the circumferential end 651B or 652B of the arc-shaped side wall 65B to the outer peripheral edge 632B or 642B of the annular upper lid 63B and the disk lower lid 64B. Extended in a curved shape). Six stopper pins 72B corresponding to each branch duct 4 are provided on the lower surface of the disk-shaped lower lid 64B so as to project at equal intervals in the circumferential direction.

  The guide walls 61B and 62B are formed, for example, as substantially parallel substantially arc-shaped side walls or substantially spiral-shaped side walls extending outward from the arc-shaped side wall 65B. The circumferential length of the radially outer guide wall 61B is longer than the circumferential length of the radially inner guide wall 62B. Further, the inner cylinder 6B is formed with an inclined guide plate 66B which is inclined from the inner surface of the arc-shaped side wall 65B toward the central portion 641B of the disk-shaped lower lid 64B. The inclined guide plate 66B may be formed in a flat plate shape or in a curved plate shape which is curved downward. The inclination angle of the inclination guide plate 66B with respect to the disk-shaped lower lid 64B is preferably about 40 to 50 degrees.

  In addition, the disk-shaped lower lid 64B of the inner cylinder 6B is connected to the housing 3B via the bearing 331B supported by the pedestal plate 33B1, and a plurality of ball bears (supporting circumferentially arranged on the pedestal plate 33B1 at the outer peripheral portion 643B) The body is horizontally supported via 332B. In addition, in the base plate 33B1, a reed switch 34B (34B1, 34B2, 34B3) for detecting the position of the outlet (outlet of the guide walls 61B, 62B) of the inner cylinder 6B around the bearing 331B corresponds to each branch duct 4. Is worn. Here, the reed switch 34B3 positioned on the front side with respect to the rotation direction (the direction of the arrow R) of the inner cylinder 6B is a leading reed switch for operating the drive portion 752B, and is circumferentially connected to the other reed switches 34B1 and 34B2. It is arranged at the position preceded by. Also, magnets 35B (35B1, 35B2) for operating the reed switches 34B (34B1, 34B2, 34B3) are mounted on the disc-like lower lid 64B of the inner cylinder 6B at a position corresponding to the outlet of the inner cylinder 6B. .

(Operation method of the second embodiment)
Next, an operation method of the second embodiment of the present air conditioner will be described with reference to FIGS. As shown in FIGS. 13 and 14A, when the human sensor 5 (see FIGS. 1 and 2) detects the worker M in a certain direction (step: ST1), the conditioned air TK of the inner cylinder 6B is obtained. It is judged by the reed switch 34B whether or not the direction of the outlet (the outlet of the guide walls 61B, 62B) for blowing the air coincides with the direction of human touch (step: ST2). That is, if the reed switch 34B (34B3) corresponding to the branch duct in which the human sensor 5 is turned on and the reed switch 34B in which the magnet 35B mounted on the inner cylinder 6B is close and turned on are different, The direction of the outlet of the tube 6B will not coincide with the human sense direction.

  Next, as shown in FIGS. 13 and 14A, when the direction of the outlet of the inner cylinder 6B does not match the direction of human touch, the reed switch 34B corresponding to the direction of the outlet of the inner cylinder 6B at the present time And the reed switch 34B3 corresponding to the human sense direction is charged. Further, the locking member 73B is lowered to release the engagement with the stopper pin 72B (step: ST3). Here, as shown in FIG. 12, when the drive portion 752B operates and the drive pin 752B1 raises one end 751B1 of the arm member 751B, the locking member 73B connected to the other end 751B3 of the arm member 751B Go down. The lowering of the locking member 73B is confirmed by turning on the reed switch 752B2 attached to the drive portion 752B. The reed switch 752B2 is turned on when the magnet 752B4 attached to the one end 751B1 of the arm member 751B approaches.

  Next, as shown in FIGS. 13 and 14B, since the engagement between the locking member 73B and the stopper pin 72B is released, the guide wall 61B is pushed by the wind pressure of the conditioned air TK, and the inner cylinder 6B rotates in the direction of arrow R (step: ST4). Then, it is determined whether or not the outlet of the inner cylinder 6B is approaching in the human sense direction by the reed switch (preceding reed switch) 34B3 in which the magnet 35B1 mounted on the inner cylinder 6B approaches (step: ST5). That is, the reed switch (preceding reed switch) 34B3 corresponding to the branch duct in which the human sensor 5 is turned on and the reed switch (preceding reed switch) 34B3 in which the magnet 35B1 mounted on the inner cylinder 6B is turned on close to each other. If and, are the same, it means that the direction of the outlet of the inner cylinder 6B is approaching in the human sense direction.

  Next, as shown in FIG. 13 and FIGS. 14B and 14C, when the outlet of the inner cylinder 6B approaches in the direction of human touch, the locking member 73B is raised and engaged with the stopper pin 72B. (Step: ST6). That is, as shown in FIG. 14B, when the blowout opening of the inner cylinder 6B approaches in the human sense direction, the magnet 35B1 mounted on the inner cylinder 6B is a reed switch (preceding reed switch) 34B3 corresponding to the human sense direction. Adjacent to each other, the reed switch (lead reed switch) 34B3 is turned on. In response to the on signal of the human sensor 5 and the on signal of the reed switch (preceding reed switch) 34B3, as shown in FIG. 11, the drive portion 752B operates and the drive pin 752B1 lowers one end 751B1 of the arm member 751B. Let At that time, the locking member 73B connected to the other end 751B3 of the arm member 751B ascends and engages with the stopper pin 72B corresponding to the branch duct 4 in the human-sense direction. It is confirmed that the reed switch 752B3 mounted on the drive portion 752B is turned on by the proximity of the magnet 752B4 that the locking member 73B is lifted.

  Next, as shown in FIG. 13 and FIG. 14 (C), the rotation of the inner cylinder 6B is stopped by the engagement member 73B engaging with the stopper pin 72B (step: ST7). When the inner cylinder 6B is stopped, the direction of the outlet of the inner cylinder 6B corresponds to the human sense direction, the other reed switches 34B1 and 34B2 in which the magnets 35B1 and 35B2 mounted on the inner cylinder 6B correspond to the human sense direction. And the other reed switches 34B1 and 34B2 are turned on.

  In the second embodiment, as shown in FIG. 15B, the locking member 73B includes four guide portions curved in a semicircular shape from the rotation center portion 733B in the rotation direction (the direction of the arrow Q). 732B, and a stopper 731B protruding inward from the tip of the guide 732B. On the other hand, in the first embodiment, as shown in FIG. 15A, the locking member 73 includes a guide portion 732 radially formed at an interval of about 90 degrees with respect to the rotation center portion 733; It consists of a stopper 731 bent inwardly in a bowl shape (U-shape) at the tip of the portion 732. Comparing the two, in the second embodiment, the stopper pin 72B abuts against the stopper portion 731B from the deceleration start position (P1) at which the stopper pin 72B abuts against the guide portion 732B and the inner cylinder 6B starts to decelerate The braking distance L2 of the inner cylinder 6B up to the stop position (P2) at which the rotation of the motor stops is shorter than the braking distance L1 of the first embodiment (see FIG. 15A). Therefore, in the second embodiment, the variation in the stop position (P2) of the inner cylinder 6B is reduced, and the conditioned air TK fed from the main duct 2 into the housing 3B corresponds to the work area where the worker M is present. It is possible to supply the specific branch duct 4 more accurately and quickly.

  By operating as described above, the air conditioner 10B supplies the conditioned air TK, which is fed from the main duct 2 into the housing 3B, to the specific branch duct 4 corresponding to the work area S1 where the worker M is located. The inner cylinder 6B can be quickly rotated without power without using a driving device such as a motor so as to meet the purpose of energy saving, and a plurality of work areas dispersed in a plane (S1 to S6) which are not on a straight line Conditioned air TK, such as cooling or heating, can be blown quickly to the worker M who has moved to.
