Further, the backrest portion 17 is provided with a back cushion portion 16 on the front surface of the back plate portion 15 fixed to adjacent support members 18 and 18 so as to have an appropriate reclining angle, and the lower end of the back plate portion 15 is The seat portion 14 is extended from the bottom plate portion 12 of the seating posture 14 to the floor G side by a predetermined dimension.
In movie theaters, theaters or concert halls, the height dimension from the floor G to the lower end of the back plate 15 of the chair body 11 is about 16 cm to 24 cm, and is most often about 17 cm.

  The lower region of the floor G is a chamber 9 for temporarily storing temperature-adjusted air. A duct (not shown) is connected to the chamber 9 and the temperature is adjusted from the air conditioner through the duct. Temperature-controlled air is introduced into the chamber 9.

A plurality of outlets 8, 8,... Communicating with the chamber 9 are provided at appropriate positions on the floor G facing the chair bodies 11, 11,. Are respectively fitted with blowing mouthpiece bodies 2, 2,... Constituting the blowing mouthpiece 1. Then, the temperature-controlled air in the chamber 9 flows out from the outlet mouthpiece bodies 2, 2,... At a blowing rate of about 30 m ³ / h to 70 m ³ / h, respectively.

4 is a plan view showing the blowout mouthpiece main body 2 shown in FIG. 1, and FIG. 5 is a cross-sectional view taken along line VV of the blowout mouthpiece main body 2 shown in FIG.
As shown in both figures, the blowout mouthpiece main body 2 has a flat-band annular flange portion 23 orthogonal to the central axis of the frame member 20 at one end edge of a cylindrical frame member 20 having an appropriate length. The frame member 20 is fitted into the outlet 8 described above, and the flange portion 23 is engaged with the peripheral portion of the outlet 8 of the floor G (see FIG. 1). .

  In the frame member 20, a first region 21 in which a plurality of first blade members 24, 24,... For allowing temperature-controlled air to flow out in the axial length direction of the central axis of the frame member 20 is installed, Are divided into a second region 22 in which a plurality of second blade members 25, 25,... That is, the inside of the frame member 20 is divided into two regions of a first region 21 and a second region 22 in the radial direction.

  The first blade members 24, 24,... Have a flat belt-like member on the inner peripheral surface of the frame member 20, and the short side (width) direction thereof is parallel to the central axis of the frame member 20. The reference line set in the diametrical direction is constructed so as to be orthogonal to the reference line at an appropriate distance in the longitudinal direction of the reference line.

  Further, the second blade members 25, 25,... Are appropriately spaced apart from the inner peripheral surface of the frame member 20 in the longitudinal direction opposite to the first blade members 24, 24,. It is erected so as to be orthogonal to the line. And when the height dimension from the floor part G to the baseplate part 12 (all refer FIG. 2) of the chair main body 11 is about 15 cm-about 20 cm, each 2nd blade | wing member 25,25, ... is a flat strip-shaped member. , The angle α formed by the axis in the short side (width) direction of the second blade members 25, 25,...

  As shown in FIG. 6, the blowout mouthpiece main body 2 has the first blade members 24, 24,... On the back plate 15 side of the chair body 11, and the second blade members 25, 25,. The first blade members 24, 24,... And the second blade members 25, 25,... Are arranged in a direction parallel to the width direction of the back plate portion 15.

  And the blower outlet main body 2 makes the above-mentioned 2nd area | region 22 and the above-mentioned 2nd area | region 22 on the diameter of the blower outlet main body 2 if the line segment extended from the lower end part of the backplate part 15 to the perpendicular downward is made into the vertical line L. Most of the first region 21 is at a position on the side of the seat 14 from the vertical line L, and the rest of the first region 21 is at a position protruding by a dimension T from the vertical line L to the side opposite to the seat 14. There is. That is, a part of the frame member 20 of the blowout outlet main body 2 is located closer to the seat portion 14 of the chair body 11 than the vertical line L, and the other part of the frame member 20 is closer to the chair body 11 than the vertical line L. Only the dimension T protrudes toward the back plate 15 side.

Here, the height dimension from the floor part G to the lower end of the back plate part 15 of the chair body 11 is about 16 cm to 24 cm, and the blowing amount from the blowing mouthpiece body 2 is about 30 m ³ / h or more and 70 m ³ / h. When it is about or less, the value of the dimension T is 0.5 cm or more and 3.5 cm or less, more preferably about 1.25 cm. When the value of the dimension T is less than 0.5 cm, the flow rate of the temperature-controlled air toward the front of the chair body 11 exceeds the required value in the lower region of the seat 14 (see FIG. 2) of the opposite chair body 11. Therefore, there is a possibility that the user sitting on the chair body 11 may feel uncomfortable. On the other hand, when the value of the dimension T exceeds 3.5 cm, the temperature-controlled air cannot be flowed to a required space area, which may cause discomfort to the user behind.

On the other hand, when the value of the dimension T is not less than 0.5 cm and not more than 3.5 cm, the temperature-controlled air can be flowed to a required space region without causing discomfort to the user seated on the chair body 11. For this reason, there is no possibility of causing discomfort to the rear user. In addition, since an appropriate amount of temperature-controlled air is also discharged to the lower region of the seat portion 14 of the chair body 11 facing the outlet, the user seated on the chair body 11 does not feel uncomfortable. A temperature control region in which conditioned air drifts is formed, and as a result, it is possible to prevent as much as possible a non-temperature-controlled atmosphere from being mixed into the temperature-controlled air guided to the required range along the back plate portion 15. Therefore, discomfort is prevented from being given to the user behind.

  Further, when the value of the dimension T is approximately 1.25 cm, the chair body 11 (see FIG. 2) and the back chair body are seated on the back chair body even if the distance between the chair body 11 and the back chair body is shorter than in other cases. It is possible to prevent the user from feeling uncomfortable.

It is guided upward on the back side.

  On the other hand, the temperature-controlled air that has flowed out from the portion located on the side of the seat portion 14 from the vertical line L of the first region 21 flows out toward the seat portion 14, but from the second region 22 of the blowout outlet main body 2 to the chair. Since the temperature-controlled air toward the back side of the main body 11 flows out, most of the temperature-controlled air is pushed out to the back plate portion 15 side of the chair main body 11 and along the back plate portion 15 of the chair main body 11 as before. The chair body 11 is guided upward on the back side.

  Further, most of the temperature-controlled air that has flowed out from the second region 22 of the blowout outlet main body 2 is directed to the back plate portion 15 side of the chair main body 11 and along the back plate portion 15 of the chair main body 11 as before. It is guided upward on the back side of the chair body 11.

  In this way, the temperature-controlled air guided upward on the back side of the chair body 11 spreads to the first diffusion region R1 around the other chair body 11 disposed at the rear of the chair body 11 by diffusion or the like, and the first One diffusion region R1 is adjusted to a required temperature.

  On the other hand, a part of the temperature-controlled air that has flowed out of the second region 22 of the blowout mouthpiece main body 2 hits the portion near the lower end of the back plate portion 15 of the chair main body 11 and the lower surface of the bottom plate portion 12 of the seat portion 14. A second diffusion region R2 in which the temperature-controlled air diffuses is generated below the portion 14.

  By the way, as described above, most of the temperature-controlled air that has flowed out of the air outlet body 2 is guided along the back plate portion 15 of the chair body 11 to the upper side on the back side of the chair body 11, so The atmosphere below the part 14 is attracted. At this time, since the second diffusion region R2 of the temperature-controlled air is generated below the seat portion 14 and the temperature-controlled air of the second diffusion region R2 is attracted, an atmosphere whose temperature is not adjusted is attracted. This can prevent the user in the first diffusion region R1 from feeling uncomfortable.

On the other hand, since the temperature of the second diffusion region R2 is adjusted by the temperature-controlled air that has flowed out to the lower region of the seat 14 of the chair body 11, the temperature of the feet of the user sitting on the chair body 11 and the upper body The difference with the ambient temperature is small. Therefore, it is possible to prevent the user from feeling uncomfortable due to the temperature difference as much as possible. Furthermore, since the temperature-controlled air that has flowed out to the lower region of the seat portion 14 of the chair body 11 is attracted to the back plate portion 15 side of the chair body 11 as described above, the temperature-controlled air is seated on the chair body 11. The user's feet are only slightly reached, and discomfort due to airflow is prevented as much as possible.
Note that the amount of temperature-controlled air that flows out from the blow-out mouthpiece main body 2 is set so that the first diffusion region R1 falls within a required space range.

In addition, in this embodiment, although the blower outlet main body 2 is provided with the 1st area | region 21 and the 2nd area | region 22 in the one frame member 20, this invention is not restricted to this, The 1st in a some frame member is provided. The blade member 24, 24,... Or the second blade member 25, 25,... May be provided, and the frame member may be combined to form the blowout mouthpiece body including the first region 21 and the second region 22. .
In FIG. 7, a step is provided between the front and rear chair bodies 11, 11, but it goes without saying that the same operations and effects can be achieved even in a flat state where there is no such step.

(Other embodiments)
8 and 9 are side cross-sectional views of a blowout mouthpiece according to another embodiment, both of which are capable of rectifying the temperature-controlled air supplied from the chamber described above.

  The blowout mouthpiece 1a shown in FIG. 8 includes the above-described blowout mouthpiece body 2 and a rectifying cylinder 5 that adjusts the airflow of temperature-controlled air supplied from the chamber.

  The straightening cylinder 5 has a flat-band annular flange portion 5b erected at one end edge of a cylindrical cylinder body 5a having an inner diameter slightly larger than the outer diameter of the blowout outlet main body 2, and the cylinder body 5a. The portion in the vicinity of the other end is a reduced diameter portion 5c having a reduced outer diameter than the other portions.

  The above-mentioned air outlet main body 2 is detachably fitted to one end of the tube main body 5a, and temperature-controlled air is prevented from leaking in the gap between the air outlet main body 2 and the tube main body 5a. An annular packing 7 is interposed.

  Also, a plurality of screw holes are inserted through the flange portion 5b of the cylinder body 5a at appropriate intervals in the circumferential direction, and the cylinder body 5a is inserted into the outlet until the flange portion 5b contacts the floor portion. The cylinder body 5a is fixed to the floor portion by screwing screws 30, 30,... Penetrating through the holes of the flange portion 5b to the floor portion.

  In such an air outlet 1a, the temperature-controlled air flows into the inside from the other end of the cylinder body 5a constituting the rectifying cylinder 5, and is parallel to the axial direction of the central axis of the cylinder body 5a. The flow is rectified in the direction and flows out from the outlet port body 2 fitted to one end of the tube body 5a.

  Thus, even if the flow of the temperature-controlled air supplied into the chamber is not in the required direction, the temperature-controlled air that has flowed into the rectifying cylinder 5 is rectified there. Temperature-controlled air is introduced into the first blade member 24, 24,... And the second blade member 25, 25,... At a required angle, and the required first diffusion region R1 and second diffusion region R2 (see FIG. 7). ) Can be generated.

  Further, in the outlet 1b shown in FIG. 9, a baffle plate 6 is fitted in an appropriate position on the other end side of the cylinder body 5a in order to improve the rectification capability.

FIG. 10 is a plan view of the baffle plate 6 shown in FIG.
As shown in FIG. 10, the baffle plate 6 is formed by providing a plurality of through holes in a disk-shaped base material 60. The inner diameter of the through hole is relatively larger than the plurality of first through holes 61, 61,... Opened in the central region C of the substrate 60, and the plurality of second through holes 62, 62 opened around the central region C. , ... are relatively small. That is, the baffle plate 6 having an outer diameter of the base material 60 of 95 mm to 150 mm is used, and the opening ratio in the central region C of 8% to 20% of the area of the base material 60 is reduced from about 70% to about 100%. The aperture ratio in the peripheral region outside the central region C is approximately 50% to approximately 80%.

  For example, in the case of the substrate 60 having a diameter of 100 mm, the inner diameter of the first through hole 61 can be 11 mm × 11 mm, and the inner diameter of the second through hole 62 can be 5 mm × 5 mm. In this case, as shown in FIG. 10, the second through hole 62 is arranged at the center position of the substrate 60, and the four first through holes 61, 61, 61, 61 are evenly arranged around the second through hole 62. To place. And the 2nd through-holes 62, 62, ... are equally arrange | positioned in the part from the center area | region C which provided these 1st through-holes 61, 61, 61, 61 to the position of the periphery vicinity of the base material 60. FIG.

  As shown in FIG. 9, the temperature-controlled air flowing into the cylinder main body 5a may be non-uniform from the center of the cylinder main body 5a to the peripheral edge of the cylinder main body 5a, but the air outlet provided with the baffle plate 6 described above. In the tool 1b, the passage of the temperature-controlled air that flows in at the peripheral edge of the cylinder body 5a is obstructed, so that the flow of the temperature-controlled air that flows unevenly at the peripheral edge of the cylinder body 5a is made uniform. In the plane parallel to the baffle plate 6, the temperature-controlled air that is substantially uniform is discharged from the blowout outlet body 2.

  Non-uniformity of the temperature-controlled air flowing into the outlet 1b is likely to occur when temperature-controlled air is supplied from a duct (not shown) connected to the cylinder body 5a into the cylinder body 5a. Even so, since it is made uniform by the baffle plate 6 as described above, the air-conditioning equipment according to the present invention connects the duct to the reduced diameter portion 5c of the cylindrical body 5a constituting the outlet 1b, It can also comprise so that temperature-controlled air may be supplied in the cylinder main body 5a.

  In addition, in the cylinder main body 5a shown in FIG.8 and FIG.9, although the case where the reduced diameter part 5c was provided in the other end side of the cylinder main body 5a was demonstrated, this invention is not limited to this, The cylinder main body 5a Needless to say, it is not necessary to provide the reduced diameter portion 5c on the other end side.

Next, the results of measuring the residual air flow velocity of the temperature-controlled air that has flowed out from the outlet port when air conditioning is performed using the air conditioning equipment according to the present invention will be described.
The following table shows the results of measuring the remaining air velocity at a plurality of positions around the chair body installed on the floors of different steps.

In addition, as the blowout mouthpiece, the diameter is 100 mm, the area of the first region is 45% of the opening area of the blowout mouthpiece, and the second area is 55% of the opening area of the blowout mouthpiece. Those having α of 18 ° were used. The amount of temperature-controlled air flowing out from the blowout mouthpiece is 50 cm ³ / h, and the height from the floor portion to the lower end of the back plate portion of the chair body is 17 cm.

  The chair body is installed on the floor with steps of 18 cm (A), 40 cm (B), 45 cm (C), and 54 cm (D), respectively, a position 95a above the floor (a), a position 75b above (b) The residual air velocity was measured at different positions from the back plate of the chair body at a position (c) above 50 cm and a position (d) of the support member supporting the chair body.

Here, when the remaining airflow speed is 0.25 m / s or less, it is preferable because it does not give the user unpleasant feeling. Therefore, in the sitting position, at a position 50 cm above the floor, which is about the height of the user's knee, the residual airflow velocity at a position about 20 cm away from the back plate of the chair body is 0.25 m / s or less, and if it is 75 cm or 95 cm above the floor, which is about the height of the chest or head of the user, it remains at a position separated by about 30 cm from the back plate of the chair body. The air velocity is preferably 0.25 m / s or less. In addition, at the position of the support member that is about the height of the user's shin, the remaining air velocity at a position that is not separated as much as possible from the back plate of the chair body is 0.25 m / s or less. Is preferred.
As is clear from Table 1, the above-described suitable conditions for the remaining air velocity were satisfied at different heights (A) to (D) at any height position.

Next, the results of comparing the effects of baffle plates that rectify the temperature-controlled air flowing into the blowout outlet main body will be described.
The comparative test consists of a blowout mouthpiece (a control example) in which the blowout mouthpiece body 2 and the baffle plate 6 are provided on the cylinder body 5a shown in FIG. 9, and a blowout mouthpiece (the comparative example) in which the baffle plate 6 is not provided. The same procedure as in Example 1 was performed except that was used. The step was 54 cm.

  Table 2 shows the results when a comparison was made by connecting a duct to the cylinder body 5a in the vertical direction, and Table 3 shows the results when a comparison was made by connecting the duct to the cylinder body 5a from the rear of the chair body. Is the result when a comparison is made by connecting a duct to the cylinder body 5a from the side of the chair body, and Table 5 shows the result when a comparison is made by connecting the duct to the cylinder body 5a from the front of the chair body.

  As is clear from Tables 2 to 5, when the distance from the back plate of the chair body whose residual air velocity is 0.25 m / s or less is compared, the duct body is connected to the cylinder body 5a from any direction. Even if it existed, the direction of the control example was shorter than the comparative example, and the outstanding rectification | straightening effect | action by the baffle plate 6 of the control example was show | played.

  Further, as apparent from Table 2, since the excellent baffle action was exerted by the baffle plate 6 even when temperature-controlled air was supplied to the cylinder body 5a from the vertical direction, it is shown in FIGS. As shown in FIG. 9, the air outlet 1b having the baffle plate 6 shown in FIG. 9 is fitted into the air outlet 8 provided in the floor G where the chamber 9 is provided, and the temperature-controlled air is supplied from the chamber 9 into the air outlet 1b. The required rectifying action can also be achieved when it is configured to directly flow in.
