Description

  The present invention relates to an air outlet device that blows conditioned air into an air conditioning target space to perform air conditioning, and more particularly, to an air outlet device for a grid system ceiling.

  In an air conditioning facility, an air outlet device that blows out conditioned air sent through a duct to an indoor space subject to air conditioning may be disposed on the ceiling in consideration of the ease of conditioned air reaching the indoor space. Many. The ceiling on which such an air outlet device is arranged is configured by supporting a ceiling panel, a lighting fixture, etc. as a single system, such as an office space in a building, with a common linear continuous support frame. In the case of a so-called system ceiling, a blower outlet device that is attached to the support frame and forms a part of the system ceiling is employed.

  In the system ceiling, because the ceiling material and air outlets are arranged along the support frame arranged in a line, it is necessary to handle the air outlets and other attachments and removals in one row along the support frame. However, there is a problem that it is not possible to deal with a simple response such as handling only the air outlet and attaching / detaching. For this reason, in recent years, the frequency of use of grid type system ceilings that enables various ceiling units including the air outlets in the ceiling to be laid out in finer units has increased.

  In conventional grid-type system ceilings (hereinafter referred to as grid ceilings), ceiling panels and lighting fixtures are supported as a single system by a support frame combined in a common grid (grid) shape. Is attached to the support frame so as to be housed in one grid together with other equipment such as lighting equipment, and forms a part of the ceiling. And the blower outlet device is generally rectangular (rectangular) in its opening portion facing the indoor space because of a combination with other ceiling-arranged devices such as lighting fixtures. As an example of such a conventional air outlet device for a grid ceiling, there is one disclosed in Japanese Patent Application Laid-Open No. 2002-310493.

JP 2002-310493 A

  A conventional grid ceiling is formed as a ceiling of a single room by combining a plurality of square basic modules composed of a plurality of grids according to the size of the room. Moreover, in an indoor space, a partition may be provided with one or a plurality of modules of the grid ceiling as one section, and the outlet device for the grid ceiling used in combination with other ceiling-arranged devices such as lighting fixtures is provided. Generally, it is arranged for each module of the grid ceiling.

  For this reason, in the case of a grid ceiling, it is desired that the blown airflow reaches the living area uniformly from the blowout port in units of one module. However, in the case of a grid ceiling, the air outlet device is arranged at the center of the module, i.e., in the interior space or partition, because the air outlet device is arranged in combination with any of a plurality of lighting fixtures that are uniformly distributed in the module. It is rare to be located in the center of the partitioned compartment, and the air outlets are unevenly distributed on the ceiling.

  As a blower outlet with such a biased arrangement, when a square blower device with a four-way blower, which has been conventionally used on the ceiling, is used, there is an area where the airflow from the blower outlet does not reach within the range of one module. In addition, the blowout on the side close to the wall or partition has a difficulty in airflow diffusion performance, such as inviting a draft in the living area, and at least two outlets are required to reach the airflow uniformly throughout the module. Therefore, it has a problem of high cost.

  Further, in the case of the grid ceiling, a suction port for taking out indoor air to the outside is provided as a slit-like opening on the side of the lighting fixture, and is often used. However, when such a suction port and a conventional air outlet device are used in combination, the air flow from the air outlet device 100 is also directed to the side where the air inlet 54 is located (see FIG. 13). A so-called short circuit, which directly enters the inlet and does not contribute to air conditioning and reduces the efficiency of indoor air conditioning, has been a problem.

  The present invention has been made to solve the above-mentioned problems, and in each module of the grid system ceiling, the air flow can reach the entire module evenly and the number of arrangements can be suppressed, and the air conditioning is achieved at low cost. It aims at providing the blower outlet apparatus which can construct | assemble a system.

  The air outlet device according to the present invention is arranged on a grid type system ceiling formed by combining one or a plurality of basic modules having a plurality of grids, and is conditioned air supplied from the upstream side to a space to be air conditioned. In a grid-type system ceiling air outlet device that blows out substantially horizontally along the ceiling, the air outlet device is arranged in the vicinity of a predetermined corner of the module, one for each module forming the ceiling. And a conditioned air that is formed as a substantially box-like body that surrounds an opening of a rectangular opening cross section through which the conditioned air passes, and is connected to the conditioned air. A blower outlet body that blows air into the air-conditioning target space, and one or a plurality of airflow guide means that are arranged in the opening inside the blower outlet body and guide the direction in which the conditioned air is blown in a predetermined direction. The The air flow guide means has a plurality of guide areas with different directions for guiding the air flow, or the directions for guiding the air flow are individually set for each of the plurality of air flow guide means, and the four outer sides of the module are The first side and the second side sandwiching the predetermined corner, the third side parallel to the first side parallel to the opening long side direction of the outlet body, and the outlet body A fourth side that is parallel to the second side orthogonal to the long side direction of the opening, and is closest to the second side of the airflow guide means, or the closest to the second side From the airflow guide means, airflow is guided toward the third side, and from the airflow guide means closest to the fourth side of the airflow guide means, or from the airflow guide means closest to the fourth side. The airflow is guided toward the fourth side, and the opening of the airflow guiding means From the middle guide region in the long side direction or the middle air flow guide means in the long side direction of the opening, the air flow in the guide region closest to the second side or the air flow guide means closest to the second side is guided. An air flow is guided in one or a plurality of predetermined directions between a direction to perform and a direction to guide the air flow of the air flow guide means closest to the fourth side or the fourth side, In the area surrounded by the three corners of the module excluding the predetermined corner and the outlet device, the outlet airflow guided by each guide region of the airflow guide means or each airflow guide means It is diffused as a synthetic air flow while traveling radially around the device.

  As described above, according to the present invention, the airflow guide means for guiding the airflow of the conditioned air in each of the plurality of directions is disposed in the opening of the rectangular opening cross section in the outlet body, and the position near the predetermined corner of the module. The air flow is radiated toward each side of the module that does not sandwich this corner, and the air flow from the opening is diffused over a wide area surrounded by the three corners of the module and the outlet device. By obtaining the state to be achieved, it is difficult to generate a part where the airflow from the blowout port does not reach in the module, and the airflow can be evenly diffused from one blowout port to almost the entire area of the module. It is sufficient to arrange the air outlet, and the cost of air conditioning can be suppressed. In addition, when the air outlet is combined with a ceiling-arranged device such as a lighting fixture, the air-conditioning problem hardly occurs even when the air outlet is disposed at a location other than the center of the module. The arrangement can be adopted as in the past, and it is unavoidable that the sole air outlet is unavoidable due to the airflow diffusion performance, and the situation where the ceiling design is damaged as a single arrangement in the center of the module can be avoided.

  Furthermore, according to the present invention, in the configuration in which the air outlet is provided in combination with the lighting equipment, and even when the suction port is provided on the side of the lighting equipment, the direction of the air flow from the air outlet is limitedly set, Since the air flow directly toward the suction port is not generated, it is possible to suppress the occurrence of a short circuit and the accompanying air conditioning efficiency reduction.

  Further, in the blowout device according to the present invention, if necessary, the airflow guide means has a rectangular or rectangular outer frame, and at least three or more openings of the blowout body in the long side direction of the opening are provided. A plurality of substantially plate-like blades that guide the airflow in a predetermined direction and are arranged side by side in the airflow guiding direction so as to cross the inside of the outer frame. It is made.

  As described above, according to the present invention, a plurality of air flow guide means are arranged side by side in the direction of the long side of the opening of the outlet body, and a plurality of blades are arranged side by side on each air flow guide means. By guiding the air flow in the direction of the air flow and evenly spreading the blown air flow to each part of the module, the air flow guide direction is appropriately set according to the direction of the blades for each air flow guiding means, and the air flow reliably reaches each part of the module Air conditioning can be appropriately performed on the entire module with a simple airflow guide structure.

  Further, the air outlet device according to the present invention is configured such that a plurality of blades of the airflow guide means are connected and fixed to each other by a thin plate-like connecting body that is parallel to the airflow guide direction of the blades, if necessary. is there.

  As described above, according to the present invention, the blades of the airflow guide means are connected and fixed to each other by the connecting body, and the plurality of blades are integrated to increase the strength of the elongated blades traversing the outer frame of the airflow guide means. It is possible to avoid the situation that the blades vibrate due to the blown airflow and abnormal noise is generated, the airflow can be reliably guided without any problem with the fixed blades, and the connecting body parallel to the airflow guiding direction also flows with the blades. The air flow guiding performance can be improved, and the influence of a flow such as a drift on the upstream side of the air flow guiding means can be reduced.

  In addition, the air outlet device according to the present invention is provided with a plurality of air flow guides in an arrangement in which the opening of the air outlet main body is divided into a plurality of portions in the short side direction of the air outlet as necessary. A partition plate that is erected and arranged across the entire opening at a central position in the short side direction of the opening sandwiched between means, and the partition plate is located inward of the air outlet main body from the blades of the airflow guiding means It is supposed to be a standing height protruding to

  As described above, according to the present invention, the partition plate disposed across the opening of the air outlet main body while being sandwiched between the plurality of air flow guiding means exceeds the blade height of the air flow guiding means. Standing toward the inside of the main body, protruding, and affecting the flow of conditioned air at the opening of the outlet body, the conditioned air flow toward the air flow guide means from the top of the outlet body to the bottom, Of the velocity component of this airflow, the transverse component perpendicular to the vertical direction is weakened by the resistance of the partition plate, and the airflow smoothly descends toward the airflow guiding means, and this airflow is appropriately guided by the airflow guiding means. It can be in a state of reaching the air conditioning target space, and the influence of the flow such as drift on the upstream side of the airflow guiding means can be reliably suppressed, and the airflow guidance controllability by the blades can be improved.

  The neck portion 10 is a cylinder having a substantially oval shape, more precisely, an oval opening cross-sectional shape in which the outer edge of the intermediate portion sandwiched between the semicircular portions of the end portion in the major axis direction is linear. The air outlet body 20 is integrally connected to the side surface of the air outlet body 20 and is disposed on the ceiling 50 together with the air outlet body, and is connected to the duct 51 for supplying conditioned air.

  As the neck portion 10 has an oval opening cross-sectional shape, the neck portion is also formed at the end in the long side direction of the air outlet main body opening portion 21 as compared with the neck portion having a conventional circular opening cross-sectional shape. The 10 openings can be made sufficiently close to each other, and the conventional structure is such that the conditioned air can easily reach a place where the air flow of the conditioned air is difficult to reach away from the neck portion.

  The air outlet body 20 is formed as a substantially box-shaped body made of a high-strength material such as metal and surrounds the opening 21 having a rectangular opening cross section through which conditioned air passes, and is assembled and arranged on the ceiling 50 in a lattice shape. The grid system is supported by a well-known support frame 52 for ceilings together with other ceiling-arranged devices such as lighting fixtures 53 (see FIG. 1).

The frame portion 22 has a substantially bowl-like shape in which a portion protruding a predetermined width outwardly on the side opposite to the inner opening 21 is formed in a circumferential direction, and further, its outermost peripheral portion is erected upward. It is the structure made into a shape. The frame body 22 is fixed to the ceiling 50 by being attached to the support frame 52 through the known attachment plate 53 or directly.

  The airflow guide means 31, 32, 33, 34, 35, 36, 37, 38 have a rectangular outer frame 30, and a plurality of substantially plate-shaped blades 30 a for airflow guidance are respectively connected to the outer frame 30. Each of the eight openings formed by dividing the rectangular openings 21 equally into four in the long side direction and two in the short side direction, respectively. It is the structure arrange | positioned and arrange | positioned in the indoor space side position in the opening part 21 inside the blower outlet main body 20. FIG.

  Each blade 30a is formed by forming a thin and long rectangular thin plate so that a cross-sectional shape perpendicular to the longitudinal direction is curved and has a rounded shape as a whole. A plurality of arrangements in which both ends are fixed and a plurality of blades 30a are arranged in parallel are defined as an air flow guide direction. Each blade 30a is a thin plate-like connecting body 30b that is parallel to the airflow guide direction of the blade 30a, and is configured such that the blade intermediate positions are connected and fixed to each other and the blades are integrated.

  In each airflow guide means 31 to 38, the airflow guide direction, that is, the direction in which the plurality of blades 30a arranged in parallel is set independently for each airflow guide means 31 to 38, and is different for each airflow guide means 31 to 38. In addition, one or more may be formed as the same airflow guide direction as necessary. In the example of the present embodiment, the airflow guiding directions of the airflow guiding units 31 and 32 are the same, and separately, the airflow guiding directions of the airflow guiding units 34 and 35 are the same.

  Specifically, the airflow is guided from the airflow guiding means 31 and 32 closest to the second side 82 of the module 80 toward the third side 83. That is, in the first airflow guiding means 31, the direction in which the blades 30a are arranged is parallel to the short side direction of the opening 21 (the longitudinal direction of the blade 30a is the same as the long side direction of the opening 21). Through the space between the blades 30 a, the airflow is blown out toward the portion of the third side 83 of the module 80 that is close to the second side 82. Further, the second airflow guide means 32 has the same arrangement configuration of the first airflow guide means 31 and the blade 30a, and the airflow blows out in the same manner as described above.

  Subsequently, in the third airflow guiding means 33, the direction in which the blades 30a are arranged is inclined 20 ° counterclockwise with respect to the opening short-side direction. , 32 is a blowout direction that is shifted by 20 °. In the third airflow guiding means 33, the airflow blows out from the opening 21 through the blades 30 a toward the middle portion of the third side 83 of the module 80.

  In the fourth airflow guiding means 34, the direction in which the blades 30a are arranged is inclined 30 ° counterclockwise with respect to the opening short side direction, and the blowing direction from the third airflow guiding means 33 is It becomes the blowout in the direction which shifted 10 degrees. In the fourth airflow guide means 34, the airflow passes from the opening 21 to between the blades 30 a toward the portion of the third side 83 of the module 80 that is closer to the fourth side 84 than the intermediate portion. Blows out.

  In the fifth airflow guide means 35, the direction in which the blades 30a are arranged is inclined 30 ° counterclockwise with respect to the opening short side direction, and is substantially the same as the blowout from the fourth airflow guide means 34. It becomes a blowout in the direction. In the fifth airflow guide means 35, the airflow blows from the opening portion 21 through the blades 30 a toward the portion closer to the fourth side 84 than the intermediate portion of the third side 83 of the module 80. put out.

  In the sixth air flow guiding means 36, the direction in which the blades 30a are arranged is inclined by 40 ° counterclockwise with respect to the opening short side direction, and the fourth and fifth air flow guiding means 34, 35 The blowing direction is 10 ° from the blowing direction. In the fourth airflow guide means 34, the airflow blows out from the opening 21 through the blades 30 a toward the part where the third side 83 and the fourth side 84 of the module 80 intersect.

Then, the airflow is guided toward the fourth side 84 from the airflow guiding means 37 and 38 closest to the fourth side 84 of the module 80.
That is, in the seventh airflow guiding means 37, the direction in which the blades 30a are arranged is inclined by 60 ° counterclockwise with respect to the opening short side direction, and the blowing direction from the sixth airflow guiding means 36 Is a blowout in a direction shifted by 20 °. In the seventh airflow guiding means 37, the airflow is blown out from the opening 21 through the blades 30 a toward the middle portion of the fourth side 84 of the module 80.

  In the eighth airflow guide means 38, the direction in which the blades 30a are arranged is inclined 120 ° counterclockwise with respect to the short side direction of the opening, and the blowing direction from the seventh airflow guide means 37 Is a blowout in a direction shifted by 60 °. In the eighth airflow guide means 38, the airflow blows out from the opening 21 through the blades 30 a toward the part where the fourth side 84 and the first side 81 of the module 80 intersect.

  With respect to the airflow guiding direction by the airflow guiding means 37, 38 closest to the fourth side 84 of the module 80 and the airflow guiding direction by the airflow guiding means 31, 32 closest to the second side 82, the opening portion In the case of each airflow guide means 33, 34, 35, 36 located in the middle of the long side direction of 21, as shown above, the airflow by these airflow guide means 33, 34, 35, 36 is the airflow guide means. The airflow guide direction of 31 and 32 and the airflow guide direction of the airflow guide means 37 and 38 are sandwiched between the airflow guide directions of the airflow guide means 37 and 38 and are guided in four predetermined directions.

  The airflow guiding means 31 to 38 individually set the direction of guiding the airflow for each of the airflow guiding means 31 to 38, and the blown airflow guided by each of the airflow guiding means 31 to 38 is the predetermined flow in the module 80. In the area 90 surrounded by the three corners 86, 87, 88 of the module excluding the corner 85, and the air outlet device 1, the air flow proceeds radially around the air outlet device 1, whereby each air flow is The airflow is influenced by mutual attraction and the like, and becomes a synthetic airflow, and diffuses in a range wider than the reach range of the single blown airflow in the region 90.

  The partition plate 25 is formed of a substantially plate-like body having a length substantially the same as the dimension in the long side direction of the opening 21 of the outlet body 20, and a plurality of airflow guide means 31-1 at the center position in the short side direction of the opening 21. The airflow guide means 31 to 38 are disposed integrally with the airflow guide 38. The partition plate 25 serves to reinforce the airflow guide means 31 to 38 that are integrally attached, and is arranged in an upright state with a larger vertical dimension than the blade 30a of the airflow guide means 31 to 38. By projecting inward from the air outlet body from 30a, the air current in the air outlet body 20, particularly the drift of the air current flowing from the neck portion 10 into the opening 21 of the air outlet body 20 is suppressed and stabilized. It has a function of appropriately guiding the air flow in the outlet main body 20 toward the air flow guiding means 31 to 38.

  The decorative grill 40 is a substantially plate-like body in which a large number of holes 41 sized to allow conditioned air to pass without resistance are formed in a predetermined regular arrangement, and the opening 21 of the outlet body 20 and the airflow guide. The means 31 to 38 are attached to the indoor side end of the outlet body 20 so as to cover the means 31 to 38. A large number of holes 41 of the decorative grill 40 are provided with a sufficient size, and the decorative grill 40 has a large opening ratio, so that the air flow guide means 31 to 38 on the inner side are difficult to see from the indoor side. There is no influence on the blow-out of the conditioned air flow guided by the air flow guiding means 31-38.

  Next, the air flow blowing state in the blower outlet apparatus based on the said structure is demonstrated. The conditioned air supplied from the duct 51 proceeds smoothly to the opening 21 of the outlet body 20 through the neck portion 10 of the outlet device 1, and the airflow guiding means 31 located on the indoor space side of the rectangular opening 21. Reach ~ 38.

  The conditioned air that has reached the airflow guide means 31 to 38 is guided by the blades 30a arranged in a predetermined direction while passing through the open portions between the blades 30a of the airflow guide means 31 to 38, and the blades 30a are aligned. Then, the air passes through the hole 41 of the decorative grill 40 and blows out into the indoor space.

  At this time, according to the arrangement of the blades 30 a in the air flow guide units 31 to 38, the air flow is the second side 82 of the third sides 83 in the air flow guide units 31 and 32 closest to the second side 82 of the module 80. Guide it toward the part close to. Further, in the airflow guiding means 37 and 38 closest to the fourth side 84, the airflow is guided so as to be directed toward the middle part of the fourth side 84 or the part where the fourth side 84 and the first side 81 intersect. To do. Furthermore, in each airflow guide means 33, 34, 35, 36 located in the middle of the long side direction of the opening 21, the airflow guide direction of the airflow guide means 31, 32 and the airflow guide direction of the airflow guide means 37, 38 Guidance is made so that the airflow is directed in each direction between.

  In this way, a state is obtained in which airflows having different blowing directions advance radially around the outlet device 1 in the region 90 surrounded by the outlet device 1 and the three corners 86, 87, 88 in the module 80. The airflow is distributed as a group of synthetic airflows while influencing each other, so that the airflow is evenly distributed to the region 90 and the blown airflow is diffused throughout the indoor space in the range of the module 80. Become.

  Thereby, the airflow of conditioned air can be made to reach the entire range of the module 80 even from the outlets disposed in the vicinity of the corner 85 of the module 80, and the air conditioning for the indoor space is performed uniformly. be able to.

  Moreover, the airflow of the conditioned air blown into the indoor space through the hole 41 of the decorative grill 40 is in a state of covering and blocking the air outlet from the room air, and accompanying the airflow of the conditioned air The indoor air to be attracted does not approach the surface portion such as the decorative grille of the air outlet, and contamination of the air outlet due to the contact with the attraction air can be prevented.

  As described above, in the air outlet device according to the present embodiment, the air flow guide units 31 to 38 that guide the air flow of the conditioned air in a plurality of directions are arranged in the opening 21 of the rectangular opening cross section in the air outlet main body 20. Then, an air flow is radially advanced from a position near a predetermined corner 85 of the module 80 toward the sides 83 and 84 of the module that does not sandwich the corner 85, and the three corners 86, 87, Since a state in which the airflow from the opening 21 is diffused is obtained in a wide area 90 surrounded by the air outlet 88 and the air outlet device 1, a portion where the airflow from the air outlet does not reach in the module 80 is unlikely to occur. Air conditioning can be achieved by evenly diffusing the air flow from one outlet to almost the entire area of the module 80, and it is sufficient to arrange one outlet for each module. A is suppressed. Further, even when the air outlet is combined with a ceiling-arranged device such as a lighting fixture and is disposed at a location other than the center of the module 80, air conditioning problems are less likely to occur. The same arrangement can be adopted as in the past, and it is unavoidable that the sole air outlet is unavoidable due to the air flow diffusion performance, and the situation where the ceiling design is damaged as a single arrangement in the center of the module can be avoided.

  In addition, in the blower outlet apparatus which concerns on the said embodiment, it is set as the structure which arrange | positions the decorative grille 40 whose hole shape becomes an oval shape as shown in FIG. 1 in the indoor space side of the airflow guide means 31-38. Not limited to this, as shown in FIG. 7, the shape of the hole 41 of the decorative grill 40 may be a rectangular shape, or may be another polygonal shape such as a rectangle or a hexagon, a circle or an ellipse, or the like. In addition, it is possible to adopt a configuration in which the airflow guide means is exposed on the indoor space side without providing the decorative grille, and the possibility that the airflow is affected in some way as the decorative grille passes through the hole is completely eliminated. By eliminating this, the guidance function by the airflow guidance means can be exhibited to the maximum extent.

  Moreover, in the blower outlet apparatus which concerns on the said embodiment, although the neck part 10 is set as the structure which arrange | positions an opening sideways in the side surface of the blower outlet main body 20, as shown in FIG. The neck portion 10 may be arranged on the upper surface of the outlet body 20 with the opening facing upward. Like the embodiment, the neck portion 10 has an oval opening cross-sectional shape. The opening of the neck portion 10 is sufficiently close to the end portion of the long side direction of the portion 21 so that the conditioned air can be easily reached.

(Second embodiment of the present invention)
In the air outlet apparatus according to the first embodiment, the eight airflow guide means 31 to 38 have four rectangular openings 21 of the air outlet body 20 in the long side direction and two in the short side direction, Each of the air flow guide means 31 to 38 is arranged in eight sections that are divided equally and guides the air flow of the conditioned air in a predetermined direction. If the opening 21 of the outlet body 20 is arranged in a state of being divided into at least three or more in the long side direction of the opening, a configuration in which a plurality of airflow guide means other than eight are arranged in the opening.

The air flow is evenly distributed in the area 90 surrounded by the three corners 86, 87, 88 of the module and the outlet device except for the corner 85 close to the outlet, and the entire indoor space in the range of the module 80 In this state, the air flow is diffused.

(Third embodiment of the present invention)
The air outlet apparatus according to the first embodiment is configured to be supported together with the lighting fixture 53 on the grid system ceiling support frame 52 assembled and arranged in a lattice shape on the ceiling 50. As shown in FIG. 10 and FIG. 11, a suction port 54 is provided on the side of the lighting fixture 53, that is, in an arrangement state in which the suction port 54 is further interposed between the blowout port and the lighting fixture 53. It can also be set as the structure supported.

  In this case, the airflow guide means for guiding the airflow of conditioned air in a predetermined direction is provided in the three corners 86, 87, 88 of the module excluding the corner 85 close to the outlet in the module 80 and the outlet device. In the enclosed area 90, the blown airflow is made to travel radially around the blowout device, and the airflow is evenly diffused in the area 90, while the airflow is not directed to the side where the suction port is located. It is possible to prevent the air from directly entering the suction port, and to reliably suppress the occurrence of a short circuit and the accompanying air conditioning efficiency reduction.

  In addition, in the blower outlet apparatus which concerns on each said embodiment, although it has set it as the structure which provides a some airflow guide means and sets several airflow guidance directions, as shown in FIG. Only the guide means 70 is provided, and the plurality of blades 70a in the airflow guide means 70 have a shape that continuously changes the airflow guide direction for each part of the blades. A plurality of different regions 71, 72, 73, 74 can be set to obtain a state in which the airflow proceeds radially around the air outlet device, and the opening becomes an obstacle to the airflow other than the blades. By eliminating the need to place almost nothing, the airflow can be guided more smoothly in multiple directions.

  Further, in the air outlet device according to each of the above embodiments, the blades of the airflow guide means are in a fixed state. However, when the air volume decreases, the flow path between the blades of the airflow guide means is narrowed. It is possible to increase the wind speed without changing the blowing direction, and to change the reach range of the guided air flow before and after the change in the air flow, so that the air flow reach range regardless of the conditioned air flow Can be maintained and the air-conditioning state can be maintained.
