Description

  BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to an outlet apparatus used for a large space air conditioning facility provided in a large scale exhibition hall, event hall or the like.

  In large-scale air-conditioning equipment provided in large-scale exhibition halls and event halls, air outlet devices such as large nozzles (double nozzles) for blowing conditioned air toward the inside of the hall have a ceiling or wall surface It is located at a high position of In such exhibition halls and event halls, curtain-like exhibits may be hung from the ceiling or screens for video may be installed, but air-conditioned air blown out from the above-mentioned air outlet device is displayed It hits objects and screens, causing problems such as the display shaking and the image being distorted.

  As for the outlet device disposed on the ceiling or wall, conventionally, one having a function to change the blowing direction of the conditioned air has been developed, but in the case of large space air conditioning, the outlet device is disposed at a high place Therefore, it is difficult to change the blowing direction of the conditioned air manually. Therefore, it has been proposed to have a mechanism that changes the blowing direction by controlling the inner cylinder of the nozzle by its own force using a temperature sensor such as a wax sensor or a shape memory alloy operated by the temperature of the conditioned air. .

  On the other hand, as an air outlet apparatus related to the present invention, for example, there is a "air outlet apparatus" described in Patent Documents 1 and 2.

  The “blow-out device” described in Patent Document 1 includes a substantially cylindrical opening frame for blowing out a gas for air conditioning into a space to be subjected to air conditioning, and an inclined end face having one end portion formed obliquely. Is formed of a substantially cylindrical body and is pivotally supported on a rotation axis parallel to any of the inclined end face of one end and the end face of the other end inside the opening region of the opening frame, and the other end is Tilting means disposed between the opening frame and the middle nozzle, which is arranged to be tiltable in a state of being projected by a predetermined length from the outlet side end face, and the middle frame and the middle nozzle, By tilting the middle nozzle by the tilting means, it is possible to change the blowing direction of the air conditioning gas to the space to be air conditioned.

  In the "blow-out port device" described in Patent Document 2, the first guide nozzle is disposed at the opening portion of the blow-out port main body which is a substantially cylindrical body, and the second guide nozzle is further provided at the opening portion of the first guide nozzle. The first guide nozzle is disposed in the second guide nozzle so that the direction of the second guide nozzle can be adjusted by the tilting means from the same direction to the downward direction according to the temperature of the conditioned air. The direction of the blowout of the conditioned air can be adjusted in the left-right direction by making it possible to tilt the guide nozzle together with the blowout body to the left and right.

Registered utility model No. 3045940 JP, 2015-94551, A

  The outlet device having a wind direction changing mechanism using a temperature sensing element senses the temperature of the conditioned air and has a function of changing the blowing direction in a preset direction, but the blowing direction is used as needed. It is impossible to adjust the In addition, since the air outlet device used for large space air conditioning is large, the wind direction changing mechanism using the temperature sensitive element does not have sufficient power and stroke and does not function.

  On the other hand, in Patent Document 1, the guide nozzle can be tilted, for example, in the horizontal direction with respect to the middle nozzle that is tilted in the vertical direction, and the degree of freedom of the blowout direction of the air flow can be increased to perform more flexible air conditioning (paragraph [0024] However, no specific structure for tilting in both the vertical and horizontal directions is described. Moreover, since the "outlet apparatus" of patent document 1 can not be operated by remote control, it is unsuitable for the large space air conditioning installation arrange | positioned at a high place.

  Further, since the “blow-out port device” described in Patent Document 2 tilts the second guide nozzle in the vertical direction by using the heat sensitive response member, it is possible to tilt the second guide nozzle arbitrarily in both the vertical direction and the horizontal direction Can not. In addition, the wind direction changing mechanism using the heat responsive member is insufficient in power and stroke for use in large space air conditioning.

  Therefore, the problem to be solved by the present invention is to provide an air outlet that can change the blowing direction of the conditioned air in the vertical direction and the lateral direction, and can be suitably used for large space air conditioning.

It can be suitably used also in large space air conditioning arranged in The control means may use a remote controller by wireless communication or infrared communication, or may use a wired connection method.

  In the blowout device, it is preferable that the first drive means be a linear actuator disposed between the outer cylinder and the annular body. Moreover, in the said blower outlet apparatus, it is desirable that a said 2nd drive means is a linear actuator arrange | positioned between the said annular body and the said inner cylinder.

  With such a configuration, a strong driving force can be obtained while achieving simplification of the drive means and compactification of the installation space of the drive means.

  In the above-mentioned outlet device, it is desirable to provide a flange part for attaching the above-mentioned outer cylinder to the above-mentioned duct or the above-mentioned wall surface.

  With such a configuration, the fixing operation to the duct or the wall surface can be facilitated, and reliable fixing can be performed.

  In the blowout apparatus, it is preferable that a bell mouth be provided to guide conditioned air blown out from the opening of the duct or the wall into the proximal end of the inner cylinder.

  With such a configuration, the conditioned air can be efficiently flowed into the inner cylinder, which is effective in improving the wind direction adjustment function.

  In the blowout apparatus, it is desirable that the inner diameter of the tip end of the bell mouth be smaller than the inner diameter of the proximal end of the inner cylinder.

  With such a configuration, it is possible to more efficiently flow the conditioned air into the inner cylinder.

  In the blowout apparatus, it is preferable that a tip end portion of the inner cylindrical body be located at a position where the tip end portion of the outer cylindrical body protrudes in a blowing direction of the conditioned air.

  With such a configuration, the directivity of the conditioned air blown out from the tip of the inner cylindrical body can be enhanced, so that the wind direction adjusting function can be further enhanced.

The inner diameter of the distal end portion 14 a of the bell mouth 14 is smaller than the inner diameter of the proximal end portion 30 b of the inner cylinder 30. The tip end portion 30 a of the inner cylindrical body 30 is located at a position projecting from the tip end portion 10 a of the outer cylindrical body 10 in the blowing direction D of the conditioned air.

  Here, the function of the first drive means 1 will be described based on FIG. As shown in FIG. 5A, when the first drive means 1 is contracted, the annular body 20 and the inner cylinder 30 rotate clockwise about the first support shaft 11, and the tip of the inner cylinder 30 Since the portion 30a is in the upward state, the conditioned air flowing in the inner cylindrical body 30 blows obliquely upward.

  As shown in FIG. 5 (b), when the first drive means 1 is expanded from the state shown in FIG. 5 (a), the annular body 20 and the inner cylinder 30 are turned counterclockwise around the first support shaft 11. Since the tip end portion 30a of the inner cylinder 30 has the same height as the base end portion 30b (the axial center of the inner cylinder 30 is horizontal), the conditioned air flowing in the inner cylinder 30 moves in the horizontal direction. Blow towards.

  As shown in FIG. 5 (c), when the first drive means 1 is expanded from the state shown in FIG. 5 (b), the annular body 20 and the inner cylindrical body 30 center on the first support shaft 11, As the tip end portion 30a of the inner cylinder 30 is turned downward by turning clockwise, the conditioned air flowing in the inner cylinder 30 blows obliquely downward.

  Next, the function of the second drive means 2 will be described based on FIG. As shown in FIG. 6 (a), when the second drive means 2 is contracted, the inner cylinder 30 rotates counterclockwise in FIG. 6 about the second support shaft 12 and the tip of the inner cylinder 30 Since the portion 30a is in the left-facing state, the conditioned air flowing in the inner cylinder 30 blows out in the diagonal left direction.

  As shown in FIG. 6 (b), when the second drive means 2 is expanded from the state shown in FIG. 6 (a), the inner cylinder 30 is rotated clockwise about the second support shaft 12, Since the distal end portion 30a and the proximal end portion 30b of the cylindrical body 30 are aligned in the direction of the axis 10c of the outer cylindrical body 10, the conditioned air flowing in the inner cylindrical body 30 blows out toward the middle in the lateral direction. .

  As shown in FIG. 6 (c), when the second driving means 2 is expanded from the state shown in FIG. 6 (b), the inner cylinder 30 is rotated clockwise about the second support shaft 12, Since the tip end portion 30a of the cylindrical body 30 is in the right-facing state, the conditioned air flowing in the inner cylindrical body 30 blows out in the diagonally right direction.

  As shown in FIGS. 6 (a) to 6 (c), the inner cylinder 30 can be rotated about the second support shaft 12 by expanding and contracting the second drive means 2, so that the conditioned air is blown out. The direction can be changed (adjusted) to the left and right.

  As shown in FIGS. 5 and 6, since the first drive unit 1 and the second drive unit 2 function independently of each other, by combining the expansion and contraction states of the first drive unit 1 and the second drive unit 2, the diagram can be obtained. As shown to 7 (a)-(d), the blowing direction of the conditioned air which blows off from the blower outlet apparatus 100 can be arbitrarily changed (adjustment).

  That is, FIG. 7 (a) shows a state in which the conditioned air is blown out obliquely upward to the left, and FIG. 7 (b) shows a state in which the conditioned air is blown out obliquely upward to the right. ) Shows a state in which the conditioned air is blown out in the diagonally lower left direction, and FIG. 7 (d) shows a state in which the conditioned air is blown out in the diagonally lower right direction.

  Thus, in the blow-out port device 100, by rotating the annular body 20 by the first drive means 1, the inner cylinder 30 can be rotated around the first support shaft 11 together with the annular body 20. The inner cylinder 30 can be rotated about the second support shaft 12 (which is perpendicular to the first support shaft 11) by rotating the inner cylinder 30 by the second drive means 2. Therefore, as shown in FIG. 2, if the axial direction of the first support shaft 11 is set to the horizontal direction, the blowing direction of the conditioned air blown out from the inner cylindrical body 30 is changed to both the vertical direction and the horizontal direction ( Can be adjusted).

  In addition, since the first drive unit 1 and the second drive unit 2 can be remotely controlled by using remotely controllable control means (not shown), the blowing direction of the conditioned air can be arbitrarily changed. It can also be suitably used in large space air conditioning where the outlet device 100 is disposed at a high place

  In the blow-out port device 100, a linear actuator is disposed between the outer cylinder 10 and the annular body 20 as the first drive means 1, and between the annular body 20 and the inner cylinder 30 as the second drive means 2. Since the linear actuator is disposed, a powerful and reliable driving force can be exhibited while achieving simplification of the driving means and downsizing of the installation space.

  The air outlet apparatus 100 includes the flange 13 for attaching the outer cylinder 10 to the duct 15. Therefore, the fixing operation with respect to the duct 15 can be facilitated, and a reliable fixation can be performed.

  Since the blowout apparatus 100 includes the bell mouth 14, the conditioned air blown out from the opening H of the duct 15 can efficiently flow into the inner cylinder 30 from the base end 30b of the inner cylinder 30, It is effective to improve the wind direction adjustment function.

  In the blowout apparatus 100, since the inner diameter of the tip end portion 14a of the bell mouth 14 is smaller than the inner diameter of the base end portion 30b of the inner cylinder 30, the conditioned air can be more efficiently flowed into the inner cylinder 30. it can

  As shown in FIG. 1, in the blow-out port device 100, the inner cylinder 30 is set to a position where the end 30 a of the inner cylinder 30 protrudes from the end 10 a of the outer cylinder 10 in the blowing direction D of the conditioned air. Since the directivity of the conditioned air blown out from the tip 30a of the body 30 can be enhanced, the wind direction adjusting function can be further enhanced.
