Description

  The present invention is arranged so as to protrude from the floor surface facing the space to be air conditioned, and the air is blown into the air conditioned space as intermittent air blowing in a plurality of directions. The present invention relates to a blowout device that can appropriately reach each part in a harmony target space.

  In a blowout device that is arranged in an indoor space subject to air conditioning and blows out conditioned air supplied through a duct, conventionally, when the ceiling of the indoor space is high, the reach of conditioned air is emphasized. When the nozzle type is other than that, a multi-layer cone type or pan type air outlet device that emphasizes the diffusibility of the conditioned air in the horizontal direction has been generally used. Such a type of air outlet device is normally arranged on the ceiling and is set so that conditioned air reaches each part of the space from above. Moreover, the floor outlet apparatus arrange | positioned on the floor is conventionally used with each said type.

Furthermore, there is an example described in Japanese Patent Application Laid-Open No. 11-230611 as a conventional air outlet device corresponding to a large indoor space other than such air outlets.
Japanese Patent Application Laid-Open No. 11-230611

  Conventional air outlet devices are configured as described above. When a large space area such as a lobby such as an airport, a station, or a bus terminal is used as a space for air conditioning, it is evenly distributed to the people's active areas near the floor. In order to harmonize air, the loss of the multi-layer cone type, pan type, nozzle type, etc. on the ceiling is large, and in order to distribute the conditioned air to every corner of the space, the air outlet is provided on the ceiling surface. It is necessary to arrange a large number at narrow intervals. For this reason, there are more incidental facilities such as ducts leading to each outlet, and the larger the space, the larger the duct facilities and the higher the installation cost. There is a problem.

  In addition, it is necessary to blow out a large amount of airflow from the outlet in order to achieve sufficient air conditioning, such as appropriately reaching warm air having the property of rising in the case of heating to the lower active area, and as a result , It had the problem that the air current constantly blows vigorously at a specific location in the activity area and feels like a draft.

  On the other hand, the floor outlet is close to the people's activity area, and the heating can be efficiently conditioned, but conversely, in the case of cooling, the stagnation occurs near the floor, and the air volume is increased to eliminate this. When it did, it had the subject that it became the condition which feels airflow as a draft.

  With respect to these conventional air outlets, the air outlet device disclosed in the publication of Patent Document 1 can efficiently perform air conditioning by blowing from a position close to the active area, but the air blowing direction and the reach distance are limited, When a large space as described above is to be air conditioned, it is necessary to disperse a large number of active areas in the space. Therefore, when actually disposed in the space, a large number of devices protruding from the floor are visible to the human eye. In addition, there was a problem that it was difficult to harmonize with the space design.

  By the way, with respect to the blowout state from the blowout device, the blown airflow is not the same as the continuous blowout state, and it is better to add strength to the airflow or intermittently blow it out at a predetermined interval. It has become clear in recent years that it is difficult to feel as a draft and gives a pleasant sensation close to the natural wind. In order to make it difficult to feel the draft in the active area, it is more desirable to use intermittent blowing at long intervals, but any of the conventional outlets is based on the premise of continuous blowing, and airflow is intermittently generated. It is difficult to blow out as it is, and it is difficult to add the function, so that complicated control and opening / closing mechanisms are required.

  The present invention has been made to solve the above problems, and by incorporating the air outlet into a columnar body having a size that is not conscious of the air outlet, it can be disposed in the vicinity of the human activity area in the air-conditioning target space. Air conditioning equipment can be prevented from becoming large-scale, and the air flow direction can be switched at predetermined intervals to intermittently blow air in each direction, ensuring both sufficient airflow reach and draft suppression. An object of the present invention is to provide an air outlet device that can appropriately perform air conditioning with respect to people's activity areas in a target space.

The blowout device according to the present invention is formed of a hollow substantially columnar body having a predetermined length to which an air-conditioning gas is supplied from one end portion, and the other end portion of the substantially columnar body is closed and the other end portion. A plurality of openings that communicate with the internal opening region are formed on the peripheral side surface in the vicinity, and the air outlet is disposed so as to protrude upward from the floor surface into the air-conditioning target space with the other end as the tip side. An air flow that divides the main body and the upper part of the opening area inside the outlet body radially into each opening, and guides the air-conditioning gas that has entered the divided areas from the lower opening area to the corresponding opening. An air flow having a guide portion and one or a plurality of closed portions that are sized so as to close a lower end portion of at least one of the regions divided by the air flow guide portion with respect to a lower opening region ; collision of the outlet body to the opening area of the lower guide portion And a blowout direction changing unit that will be rotatably disposed around a direction parallel to the rotation axis, the blowing direction switching means, to position the upper portion near the lower end of the partitioned respective regions, the predetermined rotation while rotating at a speed, said occlusion portion was turning movement having a substantially fan shape in the upper portion, and a communication with the prior SL-ku min more under the opening region and the lower end portions of the regions and the non-communicated state also the in is switched Ru at a predetermined period.

  As described above, in the present invention, the blowing direction switching means is arranged inside the outlet body that protrudes into the air conditioning target space, and a plurality of openings are arranged on the peripheral side portion of the outlet body to switch the blowing direction. By rotating the means to periodically change the state of communication between the inside of the outlet body and the opening, the air outlet for blowing the air-conditioning gas is limited to any one of a plurality of openings, and the air flow is blown. By switching the outlets to be released one after another, the airflow can be blown intermittently in a predetermined cycle in each blowing direction in front of each opening, and the airflow of the air conditioning gas reaches a wide range of people's activity area in the space On the other hand, it is possible to make it difficult to feel the airflow as a draft by intermittent blowing, and it is possible to perform efficient air conditioning without giving a draft feeling to the active area of the air conditioning target space. In addition, the air outlet body has a simple columnar appearance, and it is difficult to give a mechanical impression as an air outlet. Can be placed.

  Moreover, the blower outlet apparatus which concerns on this invention passes the open part other than the obstruction | occlusion part in the blower direction switching means from the said blower outlet main body one end part side to the other end part side as needed. It is a rotating body that is provided with one or a plurality of blade portions that receive the wind pressure of the air-conditioning gas to generate a rotational force around the rotation axis, and is rotated by the air-conditioning gas wind.

  As described above, in the present invention, the blowing direction switching means is provided with the blade portion that receives the wind pressure of the air conditioning gas to generate the rotational force, and the blade is formed from the air conditioning gas flow that has entered the blowing direction switching means. By rotating the blowing direction switching means at a predetermined rotational speed and sequentially switching the openings for blowing out the air-conditioning gas, the air flow from the openings is appropriately given the space in the space. Airflow of air-conditioning gas can be appropriately reached in people's activities, allowing efficient air-conditioning without making it feel as a draft. In addition, it is not necessary to introduce power from the outside to switch the blowing direction, and at low cost. In addition to being able to operate, the mechanism is highly reliable and easy to maintain.

  Further, in the blowout device according to the present invention, the blade portion of the blowing direction switching means changes the inclination angle of the air-conditioning gas with respect to the blowing direction switching device entering direction on at least a part of the surface of the blade portion as necessary. It is possible to adjust the rotational speed of the blowing direction switching means by changing the inclination state of the surface to change the degree of generation of rotational force.

  As described above, in the present invention, the inclination of the partial surface of the blowing direction switching means can be changed, and the inclination angle of the partial surface is appropriately adjusted and changed to adjust the state of pressure received from the airflow flowing along the blade portion. Since the rotation speed of the blowing direction switching means can be adjusted by changing the rotational force of the blowing direction switching means, the switching cycle of the air flow blown out through the opening can be changed, and the amount of air conditioning gas supplied can be supplied. Regardless of the state, it is possible to reliably set the optimal blowing cycle for the active area according to the application and the condition of the air conditioning target space, and when the device is installed at multiple locations, the supply air volume differs at each location. In addition, both can be blown out with the same period by adjustment, and controlled air conditioning can be easily performed in the same space.

  Further, in the blowout device according to the present invention, if necessary, the blade portion of the blowout direction switching means has an inclination angle with respect to the direction in which the air-conditioning gas is blown in the direction of rotation of the blade portion on the rotation direction side. The movable blade surface that can be changed, and the surface opposite to the rotation direction is a fixed blade surface fixed in an inclined state, and is a region sandwiched between the movable blade surface and the fixed blade surface in the blade portion. Is the closed portion.

  As described above, in the present invention, the side that receives the positive pressure from the airflow during rotation is positioned on the side opposite to the rotation direction of the blade portion of the blowing direction switching means, and the surface positioned in the rotation direction is movable. By changing the rotational force of the entire blowing direction switching means by appropriately changing the pressure received from the air flow of the air conditioning gas on the movable blade surface by adjusting the inclination angle by changing the inclination angle, only the inclination is changed. The adjustment can easily change the blowing period from the opening to cope with various situations, and while securing the rotational force on the fixed surface side, the overall rotational force is increased or decreased to this rotational force on the movable surface side It is easy to make subtle adjustments.

  Further, the blowout device according to the present invention is formed by the blowout direction switching means by connecting and integrating at least two substantially annular bodies having substantially the same diameter in the central axis direction with a predetermined interval between them. A rotating frame that supports the blade portion, and is rotatably disposed in the opening region with one end portion of the rotating frame as a lower side and a central axis of the rotating frame as a rotation center, and the blade portion includes the rotating frame. One or a plurality of fixed blades disposed in the rotating frame in a predetermined inclination state from one end of the rotating frame to the other end, and one end of the rotating frame at one end with a predetermined interval from one end of the fixed blade. A substantially flat movable vane plate that is arranged to be tiltable within a predetermined angle range around the one end side, and between one end side of the fixed vane plate and one end side of the movable vane plate. And a blade leading edge portion to be closed.

  As described above, in the present invention, the rotation frame, the fixed blade plate, the movable blade plate, and the blade leading edge portion are arranged as the blowing direction switching means, and the inclination angle of the movable blade plate forming the blade portion is changed, By adjusting the pressure from the airflow flowing along each blade and changing the rotational force of the blowing direction switching means, the airflow blowing period from the opening according to the rotation speed of the blowing direction switching means can be adjusted. By adjusting only the inclination of the movable vane plate, it is possible to set the optimal arrival state and blowing period regardless of the supply state of the air conditioning gas, and easily perform air conditioning corresponding to various situations. At the same time, it is possible to make the blow direction switching means simple and to have a structure in which the rotation speed can be appropriately changed, and the cost can be reduced while improving the adjustment workability.

  Further, the blowout device according to the present invention is configured so that the blowout direction switching means closes the outer periphery of the rotating frame outer periphery between the fixed blade plate and the movable blade plate on the side of the blade leading edge as necessary. Part.

  As described above, in the present invention, by disposing the outer peripheral blocking portion that closes the space between the fixed blade plate and the movable blade plate in the outer peripheral portion of the blowing direction switching means, by restricting the flow of air between the blade plates. The air-conditioning gas stream that is about to enter the blowing direction switching means does not travel from the side to the closed portion sandwiched between the blades, and is surely directed to the airflow guide unit side through the open portion. The wind pressure from the air flow of the working gas can be reliably received by each blade and converted into rotational force, and the loss can be suppressed by efficiently rotating the blowing direction switching means.

  Further, in the air outlet device according to the present invention, the air outlet main body has a predetermined inner diameter that allows the air outlet direction switching means to rotate in the vicinity of the outer periphery of the air outlet direction switching means, if necessary. It has a substantially cylindrical internal duct arranged from the side to the bottom of the means.

  As described above, in the present invention, the substantially cylindrical internal duct is disposed from the outside of the blowing direction switching means inside the outlet body to the lower side, and the supplied air-conditioning gas is provided only below the blowing direction switching means. As a result, the air flow of the air-conditioning gas is forced to enter the blowing direction switching means, and the air flow does not flow against the outer periphery of the blowing direction switching means and becomes resistance to rotation, and the blowing direction switching means is efficiently rotated. It is possible to quickly pass through the blowing direction switching means while allowing the air to reach the opening without weakening the momentum of the airflow and blow out toward the active area.

Moreover, the blower outlet apparatus which concerns on this invention makes the rotational speed of the said blowing direction switching means 2 to 4 rotations per minute as needed.
As described above, in the present invention, the rotational speed of the blowing direction switching means is set to a very low rotational speed of 2 to 4 revolutions per minute, and the air flow of the air conditioning gas is blown out from each opening at a predetermined period associated therewith. Therefore, the air flow from each opening can be given an air blowing period equivalent to that obtained by averaging the fluctuations in the spray interval based on the natural wind irregularity. Even if people in the activity area repeatedly receive the same feeling as the natural wind, even if air conditioning with an emphasis on the reach distance is performed, there is no draft in the activity area, and the blowing airflow can reach a wide range Air conditioning can be executed extremely efficiently.

Moreover, the blower outlet apparatus which concerns on this invention arrange | positions the grille which has the some guide blade arrange | positioned at the grid | lattice form outside the said opening part as needed.
As described above, in the present invention, the grille having the guide vanes is disposed in the opening, and each guide vane guides the air flow of the air conditioning gas blown out from the opening in a predetermined direction so that the air flow is blown out at each position in the opening. Can be finely adjusted within the movable range of the guide vanes in the opening, and the air flow direction and straight forward / diffusion state can be fine-tuned, and the air condition corresponding to various situations by changing the blowing state according to the application It is possible to secure the optimal reach to the activity area.

  Hereinafter, an air outlet apparatus according to an embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a front view of the air outlet device according to the present embodiment, FIG. 2 is a longitudinal sectional view of the air outlet device according to the present embodiment, and FIG. 3 is an air flow guide unit in the air outlet device according to the present embodiment. FIG. 4 is a bottom perspective view of the blowing direction switching means in the outlet device according to the present embodiment, and FIG. 5 is a rotation of the blowing direction switching means in the outlet device according to the present embodiment. FIG. 6 is a perspective view showing each inclined state of the movable vane plate in the outlet device according to the present embodiment.

  In each of the drawings, the air outlet device 10 according to the present embodiment has a hollow columnar shape in which a rectangular opening 11a is formed on the peripheral side surface and protrudes vertically upward from the floor 50 of the indoor space subject to air conditioning. An air outlet guide body 12, an airflow guide portion 12 arranged to divide the upper portion of the opening area inside the air outlet body 11 into a plurality of openings 11 a, and an air outlet below the airflow guide portion 12. It is the structure provided with the blowing direction switching means 13 of the rotationally symmetrical body arrange | positioned rotatably in the opening area | region in the main body 11. As shown in FIG.

  The outlet body 11 has a rectangular opening cross section with a side of about 1.5 m and a longitudinal dimension that reaches a position higher than the human activity area when standing on the floor 50 (about 3.5 m). It is formed as a metal hollow columnar body, one end is fixed to the floor, and the other upper end is closed, and each peripheral side surface in the vicinity of the other end communicates with the internal opening region. The conditioned air is supplied from a duct 51 inside the floor 50 at one end, and the conditioned air is blown out from the upper openings 11a to the indoor space at one end. ing. Each peripheral side surface of the air outlet body 11 has the same shape, and on each of these faces, advertisements, guidance information, etc. can be posted, and lighting fixtures can be arranged, which is used in combination with the air outlet function. Available to:

  In each opening 11a of the blower outlet body 11, a grille 14 for finely adjusting the blowout direction and preventing the inside of the blower outlet body 11 from being identified from here is provided. In addition, a shaft support portion 11 b that pivotally supports the blowing direction switching means 13 is disposed in the upper center facing the opening region in the blower outlet body 11. Further, a cylindrical internal duct 11c is disposed at a lower portion of the airflow guide portion 12 in the air outlet body 11, and the conditioned air supplied with the lower end connected to the duct 51 is guided upward.

  The airflow guide portion 12 is formed by combining metal plate-like bodies, and is disposed on the upper portion in the air outlet body 11 so that the upper portion of the opening area in the air outlet body 11 is divided into four regions for each opening portion 11a. It is the structure which divides equally and guides the conditioned air which approached into each divided area to the corresponding opening part 11a.

  The blowing direction switching means 13 includes a rotating frame 13a formed by connecting and integrating two substantially annular bodies having substantially the same diameter with a predetermined distance in the central axis direction, and one end of the rotating frame 13a. Two fixed blades 13b disposed in the rotary frame 13a in a predetermined inclination state toward the end, and one end of the rotary frame 13a is arranged at one end with a predetermined distance from one end of the fixed blade 13b. And a substantially flat movable vane plate 13c disposed so as to be tiltable within a predetermined angle range around the one end side, and between one end side of the fixed vane plate 13b and one end side of the movable vane plate 13c. The blade front edge portion 13d to be closed and the outer peripheral closing portion 13e to close the space between the fixed blade plate 13b and the movable blade plate 13c on the outer periphery of the rotary frame 13a on the side of the blade front edge portion 13d. The fixed blade 13b, the movable blade 13c, and the blade leading edge 13d form the blade.

  The blowing direction switching means 13 has an outer peripheral portion on the inner surface of the internal duct 11c below the airflow guide portion 12 in the outlet body 11 with one end of the rotating frame 13a as the lower side and the central axis of the rotating frame 13a as the rotation center. It is arranged so that it can rotate freely.

  The fixed vane plate 13b is formed of a substantially plate-like body having a curved surface, and one end of the rotating frame 13a is positioned at one end and the other end is positioned at the other end of the rotating frame 13a. In contrast, it is arranged in an inclined state over a predetermined angle range of about 90 °. The movable vane plate 13c is formed of a substantially rectangular plate body in which a round bar-like support shaft (not shown) is fixed and integrated at one end, and the support shaft is pivotally supported at the lower part of the rotating frame 13a. Thus, it is configured to be tiltable about one end side. The movable vane plate 13c has a mechanism in which the inclination angle can be adjusted by changing the fixing position of the other end of the movable vane plate 13c to the upper portion of the rotary frame 13a. The fixed position of the movable vane plate 13c at the upper part of the rotating frame 13a can be accessed from the lower side inside the blowing direction switching means 13, and when the inclination angle needs to be adjusted, the operator enters the outlet body 11 and enters the internal duct. The fixed position can be adjusted from the lower side of the blowing direction switching means 13 through 11c, and the adjustment workability is excellent.

The upper part of the blade leading edge 13d sandwiched between the fixed blade 13b and the movable blade 13c is, as the closed portion, an opening region below the blowing direction switching means 13 and each region divided by the air flow guide unit 12. This is a mechanism to prevent communication. The substantially sector-shaped region from the other end of the fixed blade 13b to the other end of the movable blade 13c at the upper end of the rotating frame 13a as the closed portion is one of the four regions divided by the airflow guide unit 12 in the opening region. The lower end portion of each of the two openings is sized so as to be closed with respect to the lower opening area, and the closed portions located at two positions which are rotationally symmetric in the blowing direction switching means 13 divide the communication range of the opening area. While being limited to two of the regions, the communication state and the non-communication state of each segmented region are sequentially switched with rotation. A space portion between the fixed blade plate 13b and the movable blade plate 13c that does not become a closed portion allows communication from the lower opening region side to the air flow guide unit 12 side as an open portion.

  The fixed vane plate 13b and the movable vane plate 13c receive wind pressure of conditioned air that is about to pass through an open part of the blowing direction switching means 13 from one end side to the other end side of the outlet body 11, and receive the wind pressure of conditioned air. Generate rotational force around the axis. Thereby, the blowing direction switching means 13 rotates the closed portion by itself while rotating at a predetermined rotational speed, and the communication state and the non-communication state between the respective regions divided by the airflow guide unit 12 and the lower opening region. Are switched at a predetermined cycle. The rotation speed is 2 to 4 rotations per minute, and the rotation speed is very slow, and the airflow is blown out from each opening portion 11a at a predetermined period associated therewith, so that the blown airflow can be made difficult to feel as a draft. In addition, the switching period of the opening part 11a which blows off airflow becomes a half of the rotation period of the blowing direction switching means 13 with the opening part of the blowing direction switching means 13 being arrange | positioned in two places used as axial symmetry.

  The blowing direction switching means 13 is curved and has a large inclined blade 13b to generate a rotational force larger than that of the movable blade 13c due to collision with the airflow. It rotates in the direction of rotation that matches the direction of pressing 13b. That is, as the airflow enters, the blowing direction switching means 13 is in a state of rotating in the direction in which the blade leading edge 13d and the movable blade 13c are positioned adjacent to the fixed blade 13b. And the inclination angle of the movable vane plate 13c located on the rotation direction side with respect to the fixed vane plate 13b is changed, and the magnitude of the force in the rotation direction received by the movable vane plate 13c from the airflow of conditioned air is changed, so that the fixed vane plate 13b. This is a mechanism for adjusting the rotational speed of the entire blowing direction switching means 13 within the range of 2 to 4 rotations per minute by changing the degree of generation of the rotational force including this amount.

  In the adjustment, if the inclination of the movable vane plate 13c is set to the same side as that of the fixed vane plate 13b, the negative pressure of the airflow flowing along the movable vane plate 13c generates a rotational force in the same direction as that of the fixed vane plate 13b, and the rotation becomes easy. (Refer to FIG. 5 (A)), it is reliably rotated even when the air volume is low. If the inclination of the movable vane plate 13c is opposite to that of the fixed vane plate 13b, a reverse rotational force is generated and becomes a restraining force against the rotational force generated in the fixed vane plate 13b, making it difficult for the entire rotation to occur (see FIG. 5 (B)), it is possible to rotate at a low rotational speed even when the air volume is large. Therefore, when the air volume is small, the upper end position of the movable vane plate 13c is set to a position close to the fixed vane plate 13b (see FIG. 6A), and the upper end position of the movable vane plate 13c is set to the fixed vane plate 13b as the air volume increases. If it adjusts so that it may keep away from (refer FIG. 6 (B), (C)), the appropriate rotational speed of the blowing direction switching means 13 can be obtained.

  Next, the air flow blowing operation in the air outlet device based on the above configuration will be described. It is assumed that an appropriate rotation speed of 2 to 4 rotations per minute is obtained in the blowing direction switching means 13 by appropriately adjusting the inclination angle of the movable vane plate 13c in advance according to the amount of conditioned air blown through the apparatus. .

  The conditioned air supplied from the duct 51 enters the internal duct 11 c of the outlet body 11, proceeds upward, and reaches the outlet direction switching means 13. When the conditioned air flow enters the blowing direction switching means 13, a rotational force is generated in the fixed blade plate 13 b and the movable blade plate 13 c in the process of passing through the open portion in the blowing direction switching means 13, and the blowing direction switching means. 13 is rotated. The blowing direction switching means 13 is limited in communication with the airflow guide portion 12 by the closed portion between the fixed blade plate 13b and the movable blade plate 13c, and the passage sectional area after the blowing direction switching means 13 is lower by that amount. The conditioned air increases the airflow velocity in the process from the blowing direction switching means 13 toward the airflow guide portion 12 and the opening portion 11a. The conditioned air stream that has reached the opening 11a is blown out toward the indoor space in the front direction of the opening 11a while being slightly displaced in the lateral direction due to the rotation of the blowing direction switching means 13.

  Of the four openings 11a, the air currents are simultaneously blown out by the blowing direction switching means 13 for two openings 11a at the opposite positions, and are opposite to each other as the blowing direction switching means 13 rotates. Blowing out in two directions is performed by sequentially changing the blowing position with the passage of time, and a state is obtained in which conditioned air is intermittently blown out in the four directions that are the front of each opening 11a. Although the reach distance to the active area can be extended by blowing from the two openings 11a at the same time as compared with the case of blowing from all four openings 11a at the same time, the airflow is switched from each opening 11a. By being blown intermittently at half the rotation period of the means 13, it is possible to give a feeling close to natural wind, and the airflow that has reached the active area is not felt as a draft.

  Moreover, although the airflow of the conditioned air which blows out attracts indoor air, not only the front of the opening part 11a but the air of the right and left back of the opening part 11a can also be attracted, and mixing with room air advances rapidly. Thus, the air conditioning effect can be uniformly applied to a wide range of activity areas.

  When finely adjusting the air flow blowing direction from the opening 11a, the angle of each guide blade 14a in the grill 14 outside the opening is adjusted. In the case of air conditioning, the guide vanes 14a are horizontal, and air that is heavier than the air in the room is blown out horizontally through the openings 11a, so that the air can be sufficiently diffused into the room before reaching the active area, thereby enhancing the cooling effect of the indoor space. It is done. On the other hand, in the case of heating, the guide vane 14a is tilted obliquely downward to the indoor space side, and warm air that is lighter than the indoor air is blown obliquely downward from the opening 11a, so that it can be surely reached below the active area, The effect of warming the space can be enhanced. In addition, by adjusting the direction of the guide vanes 14a of the grille 14, it is possible to suppress the airflow from being excessively diffused immediately after the blowout and to secure the reach distance.

  As described above, in the air outlet device according to the present embodiment, the air outlet direction switching means 13 is disposed inside the air outlet main body 11 protruding into the indoor space, and the opening is formed in the peripheral side portion of the air outlet main body 11. A plurality of openings 11a are arranged, and the blowing direction switching means 13 is rotated to periodically change the communication state between the inside of the outlet body 11 and the opening 11a, and the opening 11a that blows out the conditioned air flow is out of the plurality. Since the openings 11a for blowing out the airflow are switched one after another, the airflow can be intermittently blown at predetermined intervals in the blowing directions in front of the openings 11a. In contrast, the airflow of conditioned air can be made to reach a wide range, while the intermittent airflow makes it difficult to feel the airflow as a draft, and the airflow can be efficiently conditioned without giving a feeling of drafting to the active area of the indoor space.In addition, the air outlet body 11 has a simple columnar appearance and is difficult to give a mechanical impression as an air outlet. Like the pillars in an indoor space, the air outlet body 11 blends into a part of the space design and does not give a sense of incongruity. It can be placed, and the overall size and cost of the air conditioning equipment can be suppressed.

  In the air outlet device according to the embodiment, the air outlet body is a columnar body having a square cross-sectional shape, and the openings are arranged at four locations for each peripheral side surface. The main body may be a columnar body having a circular cross section or a polygonal cross section other than a square. Moreover, not only the number of openings corresponding to each peripheral side surface but also more or less openings may be appropriately disposed at any of a plurality of locations on the peripheral side surface. Furthermore, the opening 11a of the air outlet body 11 may be formed over the entire circumference of the air outlet body 11 as long as the air outlet position within the air outlet body 11 can be appropriately limited.

  Moreover, in the blower outlet apparatus which concerns on the said embodiment, although it is set as the structure which forms the opening part 11a of the blower outlet main body 11 as a rectangular-shaped opening, other openings, such as circular, elliptical, and polygonal, are used. It can also be an opening shape. Furthermore, the grille 14 covering the opening 11a can be set by appropriately changing the pattern of the lattice formed by the guide vanes 14a.

  Further, in the air outlet apparatus according to the above-described embodiment, the air outlet direction switching means 13 is rotated by the energy of the air flow of conditioned air and no separate driving means is used. The direction switching means can also be configured to rotate at a rotational speed of 2 to 4 revolutions per minute, as described above, and the blowing direction switching means has a simple shape with only the closed part and the open part without the blade part, and no tilt adjustment is required. However, it is possible to make it difficult to feel the airflow from each opening 11a as a draft as in the above embodiment.

  In addition, in the air outlet device according to the embodiment, it is configured to adjust the rotation angle according to the air volume by changing the inclination angle. When the air volume is small, the inclination can be adjusted automatically using a spring mechanism, a sensor, a mechanism using an actuator, etc. so as to generate a large rotational force, and the cycle can be set according to the installation location at the time of installation. In addition, when the air conditioning condition changes, such as when the supply air volume changes, manual adjustment by the operator is unnecessary, and the work cost can be reduced.

  Moreover, in the blower outlet apparatus which concerns on the said embodiment, although it is set as the structure which functions the blower outlet main body 11 as a blower outlet, in addition to this, using the double cylinder structure part of the lower part of the blower outlet main body 11, After ensuring the inside of the duct 11b as a passage for the blown airflow, a suction opening is separately provided, and a space portion outside the internal duct 11b is used as a return path for the indoor air sucked in, thereby adding a function as a suction port.
