JP-A-2000-249393 Japanese Patent Application Laid-Open No. 2001-133030

A conventional ceiling-mounted air outlet device blows out conditioned air from an opening on the lower surface that substantially matches the ceiling surface of a suspension structure, as shown in the above patent documents. In the case of horizontal blowing during cooling, etc., by utilizing the property that the flow of fluid is attracted to a smooth surface near the flow, the airflow of conditioned air blown obliquely downward from the opening is directed to the surrounding ceiling surface. By attracting the conditioned air and turning it into an air current that flows along the ceiling surface, the conditioned air is moved in a substantially horizontal direction, and the reach of the conditioned air in the indoor space is secured.

When such a conventional air outlet device is used for air conditioning in an indoor space with a skeleton ceiling, the ceiling surface is not formed by the suspended ceiling material in the indoor space with the skeleton ceiling, and the ceiling is suspended from the ceiling frame. The lower surface of the air outlet, which is installed at a lower position, is far away from the ceiling frame, allowing the conditioned air blown from the lower opening to flow along the horizontal surface of the ceiling frame, etc. as a conventional horizontal blow. I couldn't.

For this reason, when a conventional air outlet device is used in an indoor space with a skeleton ceiling, it is not possible to sufficiently extend the reach of the conditioned air in the horizontal direction, and the air conditioning capacity for the indoor space is insufficient. had an issue.

The present invention has been made to solve the above-mentioned problems. Even in a suspended installation state corresponding to a skeleton ceiling, the reachable range of the airflow in the case of horizontal blowing is sufficiently widened to ensure the air conditioning effect for the indoor space. It is an object of the present invention to provide an air outlet device that can

The air outlet device according to the present invention is installed in an air conditioning target space in which a ceiling surface is not formed by a suspended ceiling material and the ceiling frame is exposed, and is suspended from the ceiling frame to adjust the air conditioning target space. In a blower outlet device for blowing out air, an opening for blowing out conditioned air is formed as a hollow, substantially box-shaped body, provided with an opening for supplying conditioned air on its upper surface, and having a laterally long slit-shaped side surface for blowing out conditioned air. and a blowout port body that is suspended from the ceiling frame, and a tilting center axis that is parallel to the longitudinal direction of the opening in a portion near the opening of the side surface in the inside of the blowout port body. a plurality of guide vanes that can be arranged; a vane driving part that is disposed in the outlet body and operates according to the temperature of the conditioned air to tilt the guide vanes; and each opening in the outlet body. a plurality of airflow deflecting plates arranged in an inclined arrangement with respect to the front direction of the opening at a portion inside the guide vane to guide the conditioned air and impart a lateral velocity component to the discharged airflow ; However, it is fixed at a predetermined position in the air-conditioned space at a predetermined distance from the ceiling frame, and is maintained in a state of being exposed to the air-conditioned space of the ceiling frame .

As described above, according to the present invention, a horizontally elongated slit-shaped blow-out opening is provided on the side surface of a substantially box-shaped blow-out port main body that is suspended from the ceiling frame, and the orientation of the guide vane provided in the opening is adjusted. So, the blowing direction of the conditioned air can be varied from horizontal to obliquely downward, and in the case of horizontal blowing corresponding to cooling, the airflow of the conditioned air can be made to go straight from the sideways opening. The airflow blown out from the outlet advances in each direction in front of the opening, and there is no ceiling surface around the air outlet due to the hanging installation from the ceiling frame, and the airflow adheres to the ceiling surface. Even so, the airflow blown out from the opening can advance while securing a sufficient reaching distance. In addition, if the direction of the guide vanes is changed so that the airflow is blown diagonally downward, it is possible to cope with heating, and the warm conditioned air blown diagonally downward from the opening advances without immediately rising, and the airflow in the indoor space Sufficient reach can be secured.

Furthermore, an airflow deflection plate inclined with respect to the front direction of the opening is provided at a portion inside the guide vane of each opening, and the traveling speed component of the airflow in the lateral direction (horizontal direction) with respect to the front direction of each opening By adjusting the size, it is possible to appropriately balance the reaching distance of the airflow to the front side and the diffusion range in the lateral direction.

Further, in the blower outlet device according to the present invention, at least a part of the lower surface of the blower outlet main body is formed as a perforated portion in which a large number of holes are drilled in a predetermined pattern. The part blows downward air currents into the indoor space through the holes of the perforated part.

As described above, according to the present invention, a perforated portion having a large number of holes drilled in a predetermined pattern is arranged on the lower surface of the outlet body, and part of the conditioned air flows downward through each hole of the perforated portion. Even if it is difficult for the conditioned air to reach directly below the outlet main body, the airflow is directed in the front direction of the opening only by blowing out from the opening on the side. By blowing out part of the conditioned air downward from the air outlet, the conditioned air can also be sent into the living area below the air outlet body, preventing the occurrence of areas that are not subject to air conditioning, and allowing the air outlet position to be the center of the room. To appropriately air-condition a wide range of space.

Especially in the case of heating, if only blowing out from the opening on the side, the airflow is warm air that is lighter than the indoor air and tends to rise, so the range of arrival is limited, and the diffusion due to mixing with the indoor air is limited to the lower part of the outlet body. Even in situations where it is difficult for warm air to reach the lower part of the air outlet body, by blowing part of the conditioned air downward from the perforated part, warm air that tends to rise during heating can be generated. It can be smoothly directed downwards into the interior space, increasing the efficiency of heating.

Further, in the blower outlet device according to the present invention, a shielding plate having a size capable of covering the entire perforated portion from above is provided inside the blower outlet main body so that the vertical position thereof can be adjusted.

As described above, according to the present invention, the shielding plate is provided on the upper side of the perforated portion so that the vertical position thereof can be adjusted. As the interval changes, the progress of the conditioned air to the perforated part in the outlet body can be changed, so that the amount of conditioned air blown from the perforated part can be increased or decreased by adjusting the position of the shield plate. It is possible to adjust the extent to which the conditioned air blown downward through each hole of the hole reaches the area below the outlet main body, so that air conditioning can be performed more appropriately according to the conditions of the indoor space.

In addition, the blower outlet device according to the present invention optionally includes a cover attached to the outside of each side surface of the blower outlet main body so as to cover the entire side surface other than the opening, and is in a heat insulating state with respect to the side surface. It is a thing.

As described above, according to the present invention, a cover is attached to each side surface of the outlet body to cover each part of the side surface other than the opening to prevent contact between the side surface of the outlet body and the room air. By making it difficult for heat to be conducted between the side surface and the cover, for example, during cooling, warm indoor air does not come into contact with the side surface of the outlet main body, which has dropped in temperature. On the other hand, the dew condensation on the side surface of the outlet body can be reliably prevented. In addition, for example, by using a tape material or sheet material made of a heat insulating material with adhesive or adhesive on both front and back sides, the cover is attached to the side surface of the outlet main body, so that the side surface of the cover is insulated. When the condition is obtained, the heat insulating structure of the cover can be easily formed, and the cost of the entire outlet can be suppressed.

Furthermore, when parts such as screws and rivets for integrally joining the plate-shaped members forming each side of the outlet body are partially exposed on the side of the outlet body, the side of the outlet body is not covered. By being covered, only the cover can be seen on the sides, which improves the appearance and allows the installation without giving a sense of discomfort to the interior space.

Further, in the blower outlet device according to the present invention, the temperature of the lower surface of the blower outlet main body is changed by the conditioned air inside the blower outlet main body, and heat is radiated to the objects in the indoor space and the indoor air. It is a radiant heat exchange part that emits heat or absorbs heat by receiving heat radiation from objects in the indoor space and the indoor air.

As described above, according to the present invention, the temperature of the lower surface of the outlet main body is changed according to the temperature of the conditioned air inside the outlet main body, and radiant heat is exchanged with the air in the indoor space and each object. As a part, not only blowing conditioned air but also heat radiation can cause temperature changes in the indoor space, so that the conditioned air can affect areas in the room where it is difficult for the airflow of the conditioned air to reach. For example, in the case of heating where the temperature of the conditioned air is high, by radiating heat to the living area below the lower surface of the outlet main body, heat radiation from people in the living area can be reduced and the sensible temperature can be increased. In the case of cooling where the temperature of the conditioned air is low, by absorbing the heat radiated from the living area below, it is possible to promote heat dissipation from people and lower the sensible temperature, making the indoor space even more comfortable. be improved.

(First embodiment of the present invention)
A blower outlet device according to a first embodiment of the present invention will be described below with reference to FIGS. 1 to 8. FIG.
In the above figures, the blower outlet device 1 according to the present embodiment is arranged to be suspended from the ceiling skeleton 60 in the indoor space to be air-conditioned, and has a substantially box-like shape provided with an opening 12 for blowing out the conditioned air on the side surface. A blowout outlet main body 10, a plurality of guide vanes 20 arranged so as to be capable of tilting in the vicinity of the side opening portion inside the blowout outlet main body 10, and the guide vanes 20 inside the blowout outlet main body 10 being adjusted according to the temperature of the conditioned air. and an airflow deflection plate 40 that is disposed inside the guide vane 20 in the outlet main body 10 and guides the conditioned air.

The air outlet main body 10 is formed as a hollow, substantially box-shaped body consisting of six sides, and is suspended from the ceiling skeleton 60 of the indoor space. , and a horizontally long slit-shaped opening 12 for blowing conditioned air is provided on each side surface.

Around the opening 11 on the upper surface of the outlet main body 10, a cylindrical neck portion 11a is arranged in a projecting state. Further, on the upper surface of the outlet main body 10, a suspending support portion 11b protruding upward is provided for connection with a supporting tool such as a suspending bolt.

By connecting and fixing the hanging support portion 11b to a support tool such as a known hanging bolt that is fixed to the ceiling frame 60 and projected toward the indoor space, the outlet main body 10 is separated from the ceiling frame 60 by a predetermined distance. It is a structure that is fixed at a predetermined position in the indoor space (see FIG. 1 ).

Inside the outlet main body 10, two elongated rectangular guide frames 13 are arranged on each side to surround each guide vane 20. As shown in FIG.
The guide frame 13 is formed as a frame-like body made of a high-strength material such as metal and having an opening with a rectangular cross-section for accommodating the guide vane 20, and is configured to allow conditioned air to flow through the opening. Further, the end of the guide frame 13 on the indoor space side is formed in a tapered shape so as to be positioned on the opening surface of the side opening 12 .

Moreover, a cover 10 a which is in a heat insulating state with respect to the side surfaces is attached to the outside of each side surface of the outlet main body 10 so as to cover the entire side surface other than the opening 12 .
The cover 10a is attached to the side surface of the outlet main body using, for example, a tape material or sheet material made of a heat-insulating material with an adhesive or pressure-sensitive adhesive placed on both the front and back surfaces, and the gap between the cover 10a and the side surface is , the tape material or the like and the air layer other than the portion where the tape is attached can provide a heat insulating state for the side surface of the cover 10a.

The cover 10a that covers the side surfaces other than the opening 12 prevents contact between the side surface of the outlet body 10 and the room air, and in addition, heat is difficult to transfer between the side surface of the outlet body and the cover 10a. By doing so, for example, during cooling, in addition to the fact that warm indoor air does not come into contact with the side surface of the outlet main body whose temperature has decreased, the surface temperature of the cover does not decrease relative to the temperature of the indoor air, and the side surface of the outlet main body Dew condensation can be reliably prevented.

In addition, when parts such as screws and rivets for integrally joining plate-shaped members forming each surface of the outlet body 10 are partially exposed on the side of the outlet body 10, the side surface of the outlet body 10 is covered with the cover 10a, only the cover 10a can be seen on the side surface, which improves the aesthetic appearance and allows the installation without giving a sense of incompatibility to the indoor space.

Further, a central predetermined area on the lower surface of the outlet main body 10 is configured to be a perforated portion 14 in which a large number of holes are drilled in a predetermined pattern. The aperture ratio of the perforated portion 14 is set so that the downward airflow generated by the passage of the conditioned air through the holes does not sufficiently reduce the airflow speed immediately below the outlet device in the case of cooling, resulting in a draft. A few percent is preferable.

The air outlet main body 10 is suspended from the ceiling frame 60 and is located in the indoor space so as to be separated from the ceiling frame 60. The neck portion 11a is connected to the duct 61 to take in the supplied conditioned air. Air is blown into the indoor space from the openings 12 on the side, and part of the conditioned air is blown downward into the indoor space through the holes of the perforated portion 14 .

The guide vanes 20 are each formed as an elongated member having a substantially T-shaped cross section, and are positioned near the opening 12 in the outlet body 10 and at the center of the opening of the guide frame 13. The end portion is pivotally supported by the guide frame 13, and the opening 12 is tiltable about the tilting center axis parallel to the longitudinal direction of the opening 12, and arranged side by side. By adjusting the inclination angle of the guide vanes 20, it is possible to guide the blowing airflow of the conditioned air in a predetermined blowing direction.

The vane drive unit 30 utilizes a known wax-type thermoelement 31 and spring 32, and is arranged in the outlet body 10 near the location where the guide vane 20 is arranged, depending on the temperature of the conditioned air. More specifically, the guide vane 20 can be tilted by utilizing the fact that the total length of the thermo-element 31 changes according to the temperature change of the surrounding conditioned air.

The thermo-element 31 changes the projection amount of the needle portion 31b from the element main body 31a in accordance with the change of the surrounding atmosphere temperature, and the total length, that is, the end portion of the element main body 31a and the tip portion of the needle portion 31b on the opposite side is changed. It is a known device for varying the spacing. The needle portion 31b is fixed to one end of a support member 15 integrally attached to the outlet main body 10, while the element main body 31a is connected to one end of the link portion 33, and the other end is attached to the guide vane 20. The guide vane 20 can be moved through the link portion 33 that connects the portions. In addition, a spring 32 is provided between the element main body 31a and the other end of the support member 15, and the element main body 31a is urged in a direction to retract the needle portion 31b. The mechanism itself combining the thermo-element 31 and the spring 32 is well-known, and detailed description thereof will be omitted.

The vane driving portion 30 changes the overall length of the thermo-element 31 according to the temperature of the surrounding conditioned air to displace the link portion 33, so that each of the guide vanes 20 connected to the link portion 33 at its end is moved. It tilts around the central axis of tilting to change the orientation.

When the projection of the needle portion 31b cannot be maintained due to being cooled by cold conditioned air during cooling, and is compressed by the urging force of the spring 32, and the entire length of the thermo-element 31 is contracted to the maximum, the guide vane 20 is positioned at its opening. The end on the 12 side faces the side, and the entire blade is in a sideways state in which it is substantially horizontal.

On the other hand, when the entire length of the thermo-element 31 is maximized by being warmed by the warm conditioned air during heating, the guide vane 20 is in an oblique state in which the end on the opening 12 side faces downward and the entire vane is inclined. becomes.
In this manner, the blade driving section 30 tilts each guide blade 20 according to the temperature of the conditioned air, so that the guide blade 20 can be switched between the horizontal orientation and the oblique orientation.

The airflow deflecting plate 40 is formed of a substantially plate-like body, and is positioned inside the guide vanes 20 of each opening 12 in the outlet main body 10 in a state of being inclined with respect to the front direction of the opening 12 and 12 are arranged at predetermined intervals in the longitudinal direction of the opening 12, and guide the conditioned air to give a lateral (left and right) velocity component with respect to the front direction of the opening 12 to the blowing airflow.
Each airflow deflection plate 40 is attached at its end to a partition plate 45 arranged parallel to the longitudinal direction of the opening 12 inside the outlet main body 10 and fixed integrally to the outlet main body 10 .

The airflow deflection plates 40 are set at a plurality of angles of inclination with respect to the front direction of the opening 12. By guiding the airflow of the conditioned air with each of the airflow deflection plates 40, the conditioned air blown out from the opening 12 is diverted. It is a mechanism that gives the airflow a lateral (right and left) velocity component according to the inclination angle of the airflow deflection plate 40 .

The inclination angle of the airflow deflection plate 40 is set to a value that increases the inclination of the opening 12 from the front direction as the position of the airflow deflection plate 40 moves away from the center position of the opening 12 .
When the airflow of the conditioned air guided by these airflow deflection plates 40 is blown out into the indoor space 70, it progresses in the indoor space so as to spread gradually in the lateral (left and right) direction, and spreads over a wide area in the room.

The airflow deflection plate 40 corrects the state in which the conditioned air that has flowed into the outlet main body 10 from the downward duct 61 at a predetermined inflow speed flows unevenly in a part of the outlet main body 10, and the air flow deflects to the side opening. It also has a rectifying function to blow out the conditioned air from 12 evenly.

The partition plate 45 is arranged in a position inside the airflow deflection plate 40 in the outlet main body 10 so as to extend in the longitudinal direction of the opening 12 . The partition plate 45 is arranged in the outlet main body 10 so as to create a gap that allows conditioned air to flow between the airflow deflection plates 40, and one end of each airflow deflection plate 40 is attached to each airflow deflection plate. 40 is supported and fixed.

The partition plate 45 shields the corner portion of the outlet main body 10 so that only the conditioned air that has passed between the airflow deflection plates 40 exits the opening 12 and reaches the indoor space. The deflection plate 40 is designed to maximize the guiding performance.

Specifically, the airflow deflection plate 40 and the partition plate 45 are integrally structured, and a part of the plate forming the partition plate is cut and raised and bent to a predetermined inclined state to form the airflow deflection plate 40 . A partition plate 45 is used as a frame-shaped remaining portion surrounding the opening formed by the bending. In this case, the opening of the partition plate 45 serves as a passage for the conditioned air guided by the airflow deflection plate 40 .

The direction of the airflow deflection plate 40 is set so that the airflow of the conditioned air to be guided spreads laterally with respect to the front direction of the opening 12, but is not limited to this. Depending on the condition of conditioning, the direction of the airflow deflection plate is set to match the front direction of the opening 12 or to narrow the direction of the conditioned air to be guided laterally with respect to the front direction of the opening 12. It can also be used, and is suitable for cases in which more emphasis is placed on the reaching distance in the front direction than on the diffusion of the conditioned air in the lateral direction.

Next, a description will be given of the state of air conditioning to the indoor space by the air outlet device based on the above configuration. As a premise, it is assumed that conditioned air is continuously supplied to the outlet device 1 through the duct 61 .

The conditioned air sent from the duct 61 enters the outlet main body 10 through the opening 11 surrounded by the neck portion 11 a on the upper surface of the outlet main body 10 .
Then, the conditioned air advances inside the outlet main body 10, passes between the airflow deflecting plates 40, and reaches the guide frame 13 positioned closer to the indoor space.

In addition, as the conditioned air travels in each direction inside the outlet main body 10, part of it comes into contact with the blade driving unit 30, and as a result of warming or cooling the blade driving unit 30 as an atmosphere, the temperature of the blade driving unit 30 is harmonized. It follows the temperature of the air.

As the blade driving portion 30, which has the property of changing its length with temperature changes, reaches a temperature close to or the same as the conditioned air, the blade driving portion 30 forms a predetermined length according to the temperature. , the guide vane 20 connected to the vane drive unit 30 is moved to a predetermined inclined state that is preset in accordance with the temperature of the conditioned air.

While the conditioned air that has reached the guide frame 13 advances between the inner surface of the guide frame and the guide vanes 20 toward the opening 12, the advancing state is adjusted according to the inclination state of the guide vanes 20, The air is blown out from the opening 12 into the indoor space.

In the case of cooling, when the low-temperature conditioned air sent from the duct 61 enters the outlet main body 10, the thermoelement 31 of the blade driving portion 30 is brought into contact with the conditioned air so that the length thereof is reduced, and the link The portion 33 is displaced to a position near the side end portion of the outlet main body 10 , and the guide vane 20 is tilted via the link portion 33 so that the leading end thereof is separated from the inner wall of the guide frame 13 and placed in a horizontal state.

While the conditioned air travels in the guide frame 13, it travels straight toward the opening 12 side along the outer circumference of the guide vanes 20 in the sideways state. In this way, the airflow of the conditioned air is blown horizontally from the opening 12 into the indoor space 70 (see FIG. 5).

In a state in which the guide vanes 20 are oriented sideways and the conditioned air is horizontally blown out from the opening 12, the conditioned air that is cold and heavier than the indoor air is not immediately lowered and reaches far into the indoor space. As a result, the conditioned air can be sufficiently diffused in the indoor space from the height of the air outlet device until it reaches the floor surface. It attracts the relatively warm indoor air in the upper part of the indoor space where the outlet device is located and mixes with it quickly, so it can cool the room in a short time and exhibits excellent air conditioning effects.

In addition, by blowing out part of the conditioned air from the perforated portion 14 on the lower surface of the blower outlet main body 10, the living area immediately below the blower outlet main body 10 is difficult for the airflow of the conditioned air blown out from the side opening 12 to reach. The conditioned air can also be sent to the air conditioning object, and the conditioned air can reach the object without leaking from the object to be air conditioned to give a cooling effect.

On the way to the guide frame 13 after the conditioned air advances through the outlet main body 10, the airflow of the conditioned air passes between the plurality of airflow deflection plates 40, and is guided by the airflow deflection plates 40 to open the opening. By giving the lateral (left and right) velocity component to the front direction of the opening 12, the blowing air current is not concentrated too much in the front direction of the opening 12, and the conditioned air is blown evenly from the entire area of the opening 12. It will be possible to put it out. In addition, by not narrowing the traveling direction of the conditioned air, it is possible to prevent the flow of cold air from reaching the living area without reducing its speed and creating a draft when the indoor space is narrow.

On the other hand, in the case of heating, when warm conditioned air sent from the duct 61 enters the outlet main body 10 through the neck portion 11a, the thermoelement 31 of the blade driving portion 30 increases its length in contact with the conditioned air. In this state, the link portion 33 is displaced to a position close to the center of the outlet main body 10, and the guide vane 20 is tilted via the link portion 33, so that the tip of the guide vane 20 is aligned with the lower inner wall of the guide frame 13. The guide blades 20 are brought together to obliquely face.

As the conditioned air travels through the guide frame 13, it gradually travels downward along the outer periphery of the oblique guide vanes 20. - 特許庁In this way, the airflow of the conditioned air is blown obliquely downward from the opening 12 into the indoor space 70 (see FIG. 7).

In a state in which the guide vanes 20 are oriented obliquely and the conditioned air is blown obliquely downward from the opening 12, the conditioned air that is warmer and lighter than the indoor air can reach far into the indoor space without being immediately raised. The warm conditioned air can be sufficiently diffused into the living area of the indoor space, and heating can be performed efficiently. In addition, warm conditioned air attracts indoor air with a lower temperature and mixes with it quickly, so the effect of raising the temperature of the indoor air is large, and the room can be warmed in a short time, and the temperature difference with the indoor air is small. As a result, it is possible to make it difficult to feel the draft in the residential area even with an obliquely downward blowing airflow.

Further, part of the conditioned air is also blown out from the perforated portion 14 on the lower surface of the blower outlet main body 10, so that the living area directly below the blower outlet main body 10 where the airflow of the conditioned air blown out from the side opening 12 is difficult to reach. The conditioned air can also be sent to the room, and the warm conditioned air, which tends to rise lightly, can be smoothly directed to the lower living area of the indoor space, increasing the efficiency of heating.

As described above, in the blower outlet device according to the present embodiment, the horizontally elongated slit-shaped blowout opening is provided on the side surface of the substantially box-shaped blower outlet main body 10 which is suspended from the ceiling frame 60 so that the opening faces sideways. In addition to providing the portion 12, by adjusting the orientation of the guide vane 20 provided in the opening 12, the blowing direction of the airflow of the conditioned air can be varied from horizontal to obliquely downward. Since the airflow of the conditioned air can be made to go straight from the sideways opening 12, the airflow blown out from the opening 12 will proceed in each direction in front of the opening, and by hanging from the ceiling frame 60, the airflow will flow around the air outlet. Even in a state where the ceiling surface does not exist and the property that the airflow adheres to the ceiling surface cannot be used, the airflow blown out from the opening 12 can advance while securing a sufficient reaching distance. In addition, if the direction of the guide vanes 20 is changed so that the direction of the airflow is directed obliquely downward, the warm conditioned air that is blown obliquely downward from the opening 12 is allowed to advance without immediately rising, and the airflow is directed downward. It is possible to secure a sufficient reach in space.

Furthermore, an airflow deflection plate 40 inclined with respect to the front direction of the opening 12 is provided at a portion inside the guide vane 20 of each opening 12, so that the airflow deflection plate 40 is inclined with respect to the front direction of each opening 12. By adjusting the magnitude of the advancing speed component of the airflow, it is possible to appropriately balance the reach of the airflow to the front side and the diffusion range in the lateral direction.

In addition, in the blower outlet device according to the above-described embodiment, the openings 12 are provided on all four sides of the blower outlet main body 10, which is a box-shaped body, and the conditioned air is blown out from each opening 12, and the outlet main body 10, the conditioned air is sent out in four directions in the indoor space. is limited, and the conditioned air is blown only from the side where the opening 12 is provided, so that the conditioned air is sent out from the outlet main body 10 in three or less directions of the indoor space.

Further, in the blower outlet device according to the above-described embodiment, the perforated portion 14 is provided on the lower surface of the blower outlet main body 10, and the conditioned air is sent out from each hole of the perforated portion to the area directly below the blower outlet device in the indoor space. However, it is not limited to this. For example, if the indoor space to be air-conditioned is small, the influence of the airflow of the conditioned air coming out of the opening 12 also extends to the area immediately below the outlet device. If it is easy to do so, it is also possible to adopt a configuration in which no perforated portion is provided on the lower surface of the outlet main body 10 and the conditioned air is blown out only from the opening 12 on the side surface.

(Second embodiment of the present invention)
In the blower outlet device according to the first embodiment, parts other than the guide frame 13, the guide vane 20, the vane drive unit 30, and the airflow deflection plate 40 provided near the side opening 12 inside the blower outlet main body 10 In addition, as a second embodiment, as shown in FIG. A shielding plate 16 having a size capable of covering the entire hole 14 from above may be provided so that the vertical position thereof can be adjusted.

In this case, by moving the shielding plate 16 up and down to change the distance from the lower surface where the perforated portion 14 is located, the progress of the conditioned air to the perforated portion 14 in the outlet body 10 can be changed. The blowing amount of conditioned air from the part 14 can be increased or decreased by adjusting the position of the shielding plate 16, and the degree of arrival of the conditioned air blown downward through each hole of the perforated part 14 to the area below the outlet body can be adjusted. Therefore, it is possible to perform air conditioning more appropriately according to the conditions of the indoor space.

As the mechanism for adjusting the vertical position of the shielding plate 16, for example, an adjustment screw shaft is used, which is rotatably supported at the upper and lower ends within the outlet main body 10, and whose intermediate portion is screwed to the shielding plate 16. A mechanism for rotating by operation of a motor attached to the outlet main body 10 is provided to rotate the adjustment screw shaft with respect to the outlet main body 10 so that the adjustment screw shaft is screwed relative to the shield plate 16. The shielding plate 16 can be moved along with the movement of the shielding plate 16 so that the vertical position of the shielding plate 16 can be adjusted.

(Third embodiment of the present invention)
In the blower outlet device according to the first embodiment, the indoor space is air-conditioned by the conditioned air emitted from the opening 12 on the side surface of the blower outlet main body 10 and the holes of the perforated portion 14 on the lower surface. In addition to this, as a third embodiment, as shown in FIG. 10, the temperature of the lower surface of the outlet main body 10 is changed by the internal conditioned air, and the object in the indoor space and the indoor A radiant heat exchange unit 17 that emits heat to the air by thermal radiation, or absorbs heat by receiving thermal radiation from objects in the indoor space and the indoor air, and is combined with an air conditioner, It is also possible to adopt a configuration in which a cooling and heating effect due to such heat radiation can also be obtained.

In this case, even the heat radiation through the radiant heat exchange portion 17 on the lower surface of the outlet body can cause a temperature change in the indoor space, so that the conditioned air can reach the area where the air flow of the conditioned air in the indoor space is difficult to reach. For example, in the case of heating where the temperature of the conditioned air is high, by radiating heat to the living area below the lower surface of the outlet main body, heat radiation from people in the living area is reduced and the sensible temperature In addition, in the case of cooling where the temperature of the conditioned air is low, by absorbing the heat radiated from the living area below, heat dissipation from people can be promoted and the sensible temperature can be lowered. can further improve the comfort of
