Description

[Technical field]

[0001] The present invention relates to an air outlet device that is disposed on a ceiling or the like in an indoor space to be air-conditioned and blows out conditioned air into the indoor space. [Background technology]

[0002] Among the indoor spaces that are the subject of air conditioning, it has been common practice to separate the air conditioning of the inner spatial area (interior zone) from the perimeter zone, which is the area near the building's outer perimeter, which is affected by the external environment, such as the easy flow of heat in and out. Specifically, a commonly used method is to create a curtain-like air flow that covers the outer walls and windows from the inside, thermally isolating the interior zone from the outside without installing partitions that would impede people's movements, visibility, or lighting.

[0003] A line-type air outlet device has often been used to generate this type of curtain-like air flow. The line-type air outlet device has a long, thin, linear opening, which allows the outlet air flow to be concentrated in a relatively narrow area according to the shape of the opening.

[0004] When using a line-type air outlet device, in order to prevent the airflow coming out of the air outlet from attracting and diffusing indoor air, making it impossible to effectively separate the areas, the air outlet device is installed in close proximity to the exterior walls and windows that form the perimeter zone, i.e., on the ceiling near the exterior walls and windows, so that the airflow is utilized without diffusing as much as possible.

[0005] In this way, when a curtain-like air flow is to be generated, the line-type air outlet device is installed on the ceiling near an exterior wall or a window. However, in this case, the installation location of the air outlet device on the ceiling is located outside the location of the beams in a frame-type building.

[0006] Therefore, when installing a line-type air outlet device, it was necessary to carry out the work in a narrow space outside the beams in the ceiling. In addition, the duct for supplying air to the air outlet device had to be installed inside the ceiling so as to penetrate the beams from inside the building and then connected to the air outlet device. These points caused the problem of high costs for installing the air outlet.

[0007] In response to this, an air outlet device has been proposed that can obtain the desired harmonious airflow that flows near exterior walls and windows even when it is blown from a location away from the exterior walls or windows, thereby making it easier to install while ensuring that the impact of the external environment on the interior zone is suppressed. An example of such a conventional air outlet device is described in Japanese Patent No. 6896244. [Prior art documents] [Patent documents]

[0008] [Patent Document 1] Patent No. 6896244 Summary of the Invention [Problem to be solved by the invention]

[0009] Conventional air outlet devices such as those shown in the above-mentioned patent documents had the advantage that, even when placed in the interior zone of an indoor space, the airflow of conditioned air blown into the indoor space could reach the perimeter zone, while at the same time making it difficult for drafts to occur in the occupant area of ​​the interior zone.

[0010] In this conventional air outlet device, the conditioned air is guided by guide vanes arranged in a row along the longitudinal direction of the air outlet opening, so that the conditioned air flow blown out of the rectangular opening is directed diagonally downward and the horizontal component of the air flow direction is directed toward one of the short sides of the opening in the longitudinal direction.

[0011] On the other hand, the airflow of conditioned air blown out from the outlet in the interior zone is designed to reach the perimeter zone without diffusing in the interior zone, and so it is difficult to diffuse horizontally either. For this reason, it was difficult for the airflow from a single outlet to cover a wide area horizontally around the exterior walls and windows of the perimeter zone.

[0012] Specifically, it would be ideal for the airflow reach from one air outlet to cover the range of one side of a module (e.g., about 3.6 m), which is the basic unit of the horizontal length of a building's exterior wall or window, but it is difficult to diffuse conditioned air in that way. Therefore, when it is necessary to cover a wide perimeter zone, it is necessary to install multiple air outlets for the perimeter zone in the interior zone, which poses the problem of increased installation costs for the air outlets.

[0013] The present invention has been made to solve the above-mentioned problems, and has an object to provide an air outlet device that can make the conditioned air flow in multiple directions, thereby widely diffusing the conditioned air from the interior zone of the indoor space to the exterior wall or window side, even in an air outlet arrangement in which an exterior wall or window is located in the longitudinal direction of a rectangular opening. [Means for solving the problem]

[0014] The air outlet device according to the present invention is disposed on a ceiling in an indoor space to be air-conditioned and blows out conditioned air into the indoor space, and comprises: an air outlet main body formed as a substantially box-like body surrounding an opening having a rectangular opening cross section through which the conditioned air can pass, to which the conditioned air is supplied within the ceiling and which blows out the conditioned air from the opening into the indoor space; air flow guiding sections arranged in a plurality of sets in the opening of the air outlet main body in the longitudinal direction of the opening, each of which guides the conditioned air in a predetermined direction toward an exterior wall or window facing the indoor space; and a decorative grill formed of a substantially plate-like body having a size that at least covers the opening of the air outlet main body, having a plurality of through holes formed in a row to allow the conditioned air to pass through, and disposed at an end of the air outlet main body on the indoor space side, The airflow guiding section is arranged so that one longitudinal end of the opening faces an exterior wall or window, and is disposed at a predetermined location on the ceiling away from the exterior wall or window, the airflow guiding section has a plurality of approximately plate-shaped guide vanes arranged at predetermined intervals in a predetermined direction inclined with respect to the longitudinal direction of the opening of the air outlet body, and is capable of guiding harmonious air diagonally downward along the guide vanes, and of the airflow guiding sections, a first airflow guiding section that is proximal to the exterior wall or window has the guide vanes arranged in a predetermined one direction inclined with respect to the longitudinal direction of the opening, and a second airflow guiding section that is distal to the exterior wall or window has the guide vanes arranged in a predetermined other direction inclined opposite to the first airflow guiding section with respect to the longitudinal direction of the opening.

[0015] According to the present invention, a plurality of airflow guides are arranged in the longitudinal direction of the rectangular opening of the air outlet body provided on the ceiling, and the conditioned air that flows into the opening of the air outlet body is guided and blown out obliquely toward an exterior wall or window by each guide vane of each airflow guide at the opening, and each airflow blown out in a plurality of directions based on the different guide directions set for each airflow guide proceeds through the room toward the exterior wall or window, so that the conditioned air flow can reach a wide area of ​​the exterior wall or window from the air outlet position on the ceiling away from the exterior wall or window without diffusing into the interior zone as much as possible, and a curtain-like airflow can be generated that covers the exterior wall or window. This curtain-like airflow can suppress the influence of the external environment through the exterior wall or window, making it easier to maintain the air-conditioned state in the interior zone, and reducing the cost of air conditioning.

[0016] Furthermore, as necessary, the air outlet device of the present invention has a cylindrical neck portion that is connected to an air supply duct in the ceiling to allow conditioned air to flow in, and a shutter that adjusts the flow rate of conditioned air blown out from the air outlet body, and the neck portion protrudes outward from the longitudinal center of the air outlet body and is provided with the interior connected to the opening, and the shutter consists of a plate-shaped fixed portion and a movable portion, each of which has a plurality of through holes arranged at a predetermined interval, and is arranged so that when the fixed portion and the movable portion are overlapped, the interior of the air outlet body is divided into upper and lower portions at a position below the neck portion and above the air flow guide portion, and the movable portion can be shifted relative to the fixed portion in the direction in which the through holes are arranged to adjust the degree of communication between the through holes in the fixed portion and the movable portion.

[0017] Thus, according to the present invention, a shutter is provided above the multiple air flow guiding sections, making it possible to adjust the flow rate of conditioned air heading toward each air flow guiding section, and as the conditioned air that flows in through the neck section in the center of the air outlet body heads toward each air flow guiding section through each through hole of the shutter, a flow is generated inside the air outlet body along the plate-shaped shutter, partially influencing the lateral velocity component of the air flow blown out. In addition, by adjusting the opening of the shutter, the flow rate of the conditioned air can be changed. When the flow rate is narrowed, the influence of the guiding effect of the shutter becomes stronger, and the horizontal velocity component of the air flow of the conditioned air blown out from each air flow guiding section is increased, making it easier for the conditioned air to reach the exterior wall or window even when the flow rate is low. This promotes the generation of an air flow of conditioned air that covers the exterior wall or window, thereby suppressing the impact of the external environment through the exterior wall or window, and ensuring the maintenance of air conditioning in the interior zone.

[0018] Furthermore, in the air outlet device according to the present invention, as necessary, the neck portion is provided on one of the sides parallel to the longitudinal direction of the opening in the air outlet body, and the one direction in which the guide vanes in the first air flow guide portion are arranged is inclined toward the opposite side of the side of the air outlet body on which the neck portion is located, with respect to the longitudinal direction of the opening.

[0019] Thus, according to the present invention, the direction in which the guide vanes in the first airflow guiding section are arranged is inclined toward the opposite side to the side where the neck section is located, with respect to the neck section located on the side of the air outlet main body, and the conditioned air flowing in sideways from the neck section is guided directly by the first airflow guiding section in a direction away from the side where the neck section is located. This allows the conditioned air that has flowed into the air outlet main body through the neck section to be blown out from the first airflow guiding section without losing momentum of the airflow, so that the airflow of the conditioned air proceeds from the first airflow guiding section into the indoor space with almost no reduction in speed, and the first The flow velocity of the conditioned air blown out from the first air flow guiding section can be made greater than the flow velocity of the conditioned air blown out from the second air flow guiding section through a path with a large change in direction of travel, such as being guided by the second air flow guiding section in a direction returning to the side side where the neck portion is located, and particularly during cooling operation, the faster airflow of conditioned air blown out from the first air flow guiding section moves through the indoor space while drawing in the slower airflow of conditioned air blown out from the second air flow guiding section, thereby encouraging the airflow to move toward the outer wall or window side, and since the downward movement of the airflow is relatively suppressed, drafts in the living area can be reliably prevented.

[0020] Furthermore, as necessary, the air outlet device of the present invention has a first partition plate arranged in the upper space inside the air outlet body above the shutter, in an orientation perpendicular to the longitudinal direction of the opening, and the first partition plate is positioned at a predetermined position dividing the upper space into two in the longitudinal direction of the opening, thereby partially restricting the movement of conditioned air in the upper space and making the flow rate of conditioned air blown out from the second air flow guiding section greater than the flow rate of conditioned air blown out from the first air flow guiding section.

[0021] Thus, according to the present invention, a first partition plate is provided which separates the upper space above the shutter inside the air outlet body, and this first partition plate separates the conditioned air into that which mainly flows toward the first air flow guide section and that which mainly flows toward the second air flow guide section. The position of the first partition plate is set so that the flow rate of the conditioned air blown out from the second air flow guide section is greater than the flow rate of the conditioned air blown out from the first air flow guide section, and the conditioned air is blown out from each air flow guide section. As the conditioned air proceeds into the indoor space in a state in which the flow rate of the conditioned air blown out from the second air flow guide section is greater than the flow rate of the conditioned air blown out from the first air flow guide section, the flow of the conditioned air blown out from the second air flow guide section is less likely to be drawn in part by the flow of the conditioned air blown out from the adjacent first air flow guide section and to proceed under the influence of that air flow, and particularly during heating, the conditioned air blown out from the second air flow guide section can proceed smoothly downward in the indoor space, improving the air conditioning effect.

[0022] Furthermore, if necessary, the air outlet device of the present invention has a second partition plate arranged in an orientation parallel to the longitudinal direction of the opening, in a region of the upper space inside the air outlet body that is distal to the outer wall or window than the first partition plate, and the neck portion is provided on one of the sides of the air outlet body that are parallel to the longitudinal direction of the opening, and the second partition plate is arranged at a predetermined position that divides the part of the region closer to the shutter into two in the short direction of the opening, thereby partially restricting the movement of conditioned air in the region, so that the flow rate of conditioned air passing through at least the shutter and heading toward the second airflow guiding section is uniform in the short direction of the opening.

[0023] Thus, according to the present invention, in the upper space above the shutter inside the air outlet main body, a second partition plate is provided which further divides one of the regions divided by the first partition plate in the short direction of the opening, thereby partially restricting the progress of the conditioned air which flows sideways into this region through the neck portion, and by appropriately adjusting the ratio of the portion of the conditioned air which passes over the top of the second partition plate and flows downward between the side opposite to the side on which the neck portion is located and the second partition plate, and the portion which does not pass over the second partition plate and flows downward between this second partition plate and the side on which the neck portion is located, the flow rate of the conditioned air which flows toward the second airflow guide portion is uniform at each position in the short direction of the opening. In this way, the conditioned air reaches and is guided without bias to each guide vane in the second air flow guiding section, so that regardless of which side the neck portion, which causes the conditioned air to flow in sideways, is located, the conditioned air in one area of ​​the upper space is prevented from simply traveling straight to the side side opposite the side where the neck portion is located, and the conditioned air can be made to reach each part of the second air flow guiding section below without bias.By appropriately guiding the blow-out by each guide vane, even if the flow rate of the conditioned air blown out from the second air flow guiding section is increased, it can be directed in the desired direction without any problems, and the purpose of covering the exterior wall or window with the conditioned air flow can be reliably achieved.

FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0025] Hereinafter, an air outlet device according to one embodiment of the present invention will be described with reference to Figs. In each of the above figures, the air outlet device 1 of this embodiment is a device that is arranged in a grid-type system ceiling 60 and blows out conditioned air into the indoor space 90 to be air-conditioned, and is located in the so-called interior zone of the ceiling 60, at multiple specified locations located near the windows 70 on the outer periphery of the building.

[0026] The ceiling 60 is constructed based on a predetermined module (for example, a 3.6m x 3.6m module), and is a so-called grid ceiling, formed by arranging ceiling construction components (ceiling materials, lighting fixtures, air conditioning fixtures, etc.) that fit within a square frame in a grid pattern so that a predetermined number of components are arranged in the area of ​​one module. For example, if the module is 3.6m x 3.6m, one module will be a grid of 6 x 6 = 36 ceiling construction components.

[0027] In detail, the air outlet device 1 is formed as an approximately box-shaped body surrounding an opening 11 with a rectangular opening cross section, and is configured to include an air outlet body 10 arranged at a predetermined location on a ceiling 60, two air flow guiding sections 21, 22 arranged side by side at the opening 11 of the air outlet body 10 and guiding the conditioned air in a predetermined direction, an approximately plate-shaped shutter 30 arranged above the air flow guiding sections 21, 22, a first partition plate 41 arranged in an upper space 18 inside the air outlet body 10 above the shutter 30, a second partition plate 42 arranged in a region 19 of the upper space 18 that is distal to the window 70 from the first partition plate 41, and a decorative grill 50 arranged at the indoor end of the air outlet body 10.

[0028] The ceiling 60 to which this air outlet device 1 is to be attached is formed by combining a plurality of square areas 80 including a 6×6 grid, which corresponds to one module, as basic units. In the square areas 80 adjacent to the perimeter zone where the window 70 is located, the air outlet devices 1 are disposed at predetermined locations close to the window 70 with one of their longitudinal directions facing the window 70 (see FIG. 15). In addition to the air outlet device 1, another air outlet device 100 for conditioning the air for the interior zone of the indoor space 90 can also be disposed in the same area 80.

[0029] The air outlet body 10 is formed as an approximately box-shaped body made of a high-strength material such as metal, surrounding an opening 11 with a rectangular cross-section through which harmonious air can pass, and is configured so that one end in the longitudinal direction of the opening 11 faces a window 70 facing the indoor space 90, and is disposed at a predetermined location in the ceiling 60 away from the window 70.

[0030] This air outlet body 10 is configured to be supported by a known support frame 62 for a grid-type system ceiling that is assembled and arranged in a grid pattern on a ceiling 60 (see FIG. 11). The air outlet body 10 also has a cylindrical neck portion 15 that is connected to an air supply duct 61 in a ceiling 60 and through which conditioned air flows in.

[0031] The neck portion 15 protrudes laterally outward from the longitudinal center of one of the side surfaces of the air outlet body 10 that are parallel to the longitudinal direction of the opening 11, and is provided so that the inside of the neck portion 15 communicates with the opening 11. The neck portion 15 is a cylinder having a generally elliptical opening cross-sectional shape, more precisely an elliptical opening cross-sectional shape with a straight outer edge of the middle portion sandwiched between semicircular portions at both ends in the major axis direction.

[0032] The air outlet body 10 is supplied with conditioned air from the duct 61 through the neck portion 15 within the ceiling 60. The air outlet body 10 then blows the supplied conditioned air from the lower portion of the opening 11 facing the indoor space 90, through the guides of the airflow guides 21, 22, into the indoor space 90, toward the window 70 on the outer periphery of the building.

[0033] The air flow guide sections 21, 22 are configured as two sets arranged side by side in the longitudinal direction of the opening 11 at a position closer to the indoor space in the opening 11 of the air outlet body 10, and each guides the conditioned air in a predetermined direction toward the window 70 facing the indoor space 90.

[0034] The air flow guiding sections 21, 22 are composed of a first air flow guiding section 21 on the proximal side of the window 70 and a second air flow guiding section 22 on the distal side of the window 70. Each of the air flow guiding sections 21, 22 has a configuration including a plurality of substantially plate-shaped guide vanes 25 arranged at predetermined intervals in a predetermined direction inclined with respect to the longitudinal direction of the opening 11 of the air outlet body 10.

[0035] In the airflow guide sections 21, 22, the conditioned air is guided along each guide vane 25 while passing between the air outlet body 10 and the guide vane 25 and between each guide vane 25, thereby making it possible to guide the conditioned air obliquely downward in a predetermined direction toward the window 70.

[0036] Of the air flow guiding sections 21 and 22, the first air flow guiding section 21, which is closer to the window 70, has the guide vanes 25 aligned in a predetermined direction inclined with respect to the longitudinal direction of the opening 11. Strictly speaking, this direction is inclined at a predetermined angle from the direction toward one longitudinal end of the opening 11.

[0037] On the other hand, the second air flow guiding section 22, which is distal to the window 70, has the guide vanes 25 aligned in a predetermined other direction inclined away from the first air flow guiding section 21 with respect to the longitudinal direction of the opening 11. Strictly speaking, this other direction is inclined at a predetermined angle from the direction toward one longitudinal end of the opening 11 toward the opposite side to the one direction in the first air flow guiding section 21.

[0038] Specifically, one direction in which the guide vanes 25 are arranged in the first airflow guiding portion 21 is inclined at about 60° counterclockwise in Fig. 2 from the direction toward one end of the longitudinal direction of the opening 11. The one direction in which the guide vanes 25 are arranged in the first airflow guiding portion 21 is inclined toward the opposite side to the side of the air outlet body 10 on which the neck portion 15 is located, with respect to the longitudinal direction of the opening 11, or more precisely, with respect to the direction toward which one end of the longitudinal direction of the opening 11 faces.

[0039] 2. The other direction in which the guide vanes 25 are arranged in the second air flow guide portion 22 is inclined by about 45° clockwise in FIG. 2 from the direction in which one end of the opening 11 in the longitudinal direction faces. The directions in which the guide vanes 25 in the first air flow guide portion 21 and the second air flow guide portion 22 are arranged are the air flow guide directions of the air flow guide portions.

[0040] A partition plate 26 is disposed between the first air flow guiding section 21 and the second air flow guiding section 22, and this partition plate 26 divides the portion of the opening 11 where the air flow guiding sections 21, 22 are located near the indoor space, thereby creating two opening areas where the air flow guiding sections 21, 22 are located.

[0041] The partition plate 26 is disposed offset from the middle position of the opening 11, so that the first air flow guide portion 21, which is proximal to the window 70, is slightly larger than the second air flow guide portion 22, which is distal to the window 70.

[0042] Each guide vane 25 of the air flow guide section 20 has its side end attached to the inner surface of the air outlet body 10 and is fixed integrally to the air outlet body 10 in an arrangement in which the guide vanes 25 diagonally cross the opening 11 at a position closer to the indoor space in the opening 11.

[0043] The guide vanes 25 are arranged so that the end portion close to one longitudinal end portion of the opening 11 facing the window 70 is at the bottom, and when the conditioned air flows along each guide vane 25, it obtains a velocity component that tends to flow in one direction along which the guide vanes 25 are arranged or in another direction. Then, guided by the inclined guide vanes 25, the conditioned air flow is blown out obliquely downward into the indoor space 90.

[0044] In the first airflow guiding section 21 located on the side of the opening 11 closer to the window 70, the guided airflow of the conditioned air that has passed between the guide vanes 25 adds a velocity component that tends to move in one direction in which the guide vanes 25 are arranged. This velocity component is combined with the velocity component that the airflow had inside the opening 11 before it flowed into the first airflow guiding section 21, so that the horizontal component of the airflow's traveling direction tends to move diagonally downward through the indoor space 90, with the horizontal component of the airflow shifted from the one direction in which the guide vanes 25 are arranged to the direction in which one longitudinal end of the opening 11 faces (airflow A in Figures 12, 13, and 14).

[0045] Furthermore, in the second airflow guiding section 22 located on the side of the opening 11 farther from the window 70, a velocity component that tends to move in the other direction of the guide vanes 25 is added to the airflow of the conditioned air that has passed between the guide vanes 25, due to the guidance of the guide vanes 25. This velocity component is combined with the velocity component that the airflow had inside the opening 11 before it flowed into the second airflow guiding section 22, and the airflow of the conditioned air tends to move diagonally downward through the indoor space 90, with the horizontal component of its traveling direction shifted from the other direction in which the guide vanes 25 are arranged to the direction toward one longitudinal end of the opening 11 (airflow B in Figures 12, 13, and 14).

[0046] In reality, the airflow blown out from the first airflow guiding section 21 and the airflow blown out from the second airflow guiding section 22 of the opening 11 are generated simultaneously, so after being blown out, the airflows attract each other and further change their traveling direction slightly. That is, the traveling direction of the airflow of the conditioned air after being blown out from the first airflow guiding section 21 becomes a predetermined direction further shifted toward the direction of one end of the longitudinal direction of the opening 11. In addition, the traveling direction of the airflow of the conditioned air after being blown out from the second airflow guiding section 22 also becomes a predetermined direction further shifted toward the direction of one end of the longitudinal direction of the opening 11.

[0047] Furthermore, depending on the state of the conditioned air, the airflow of conditioned air blown out from the first airflow guiding section 21 and the airflow of conditioned air blown out from the second airflow guiding section 22 may have a stronger influence on each other, causing a greater change in the direction of travel of one or both of the airflows.

[0048] In this way, although the harmonious air is guided in a direction slightly different from that based on the arrangement of each guide vane 25 in each air flow guide section 21, 22, the air flow maintains its state of moving in two diagonally downward directions and proceeds toward the window 70 without diffusing much. Then, after reaching the window 70, the airflow of the conditioned air further travels downward and sideways along the window 70, and covers the window 70 as a curtain-like airflow (see FIG. 16).

[0049] In addition, each air flow guiding section 21, 22 is provided in a rectangular area of ​​different size obtained by unequally dividing the opening 11 in the longitudinal direction, and the two air flow guiding sections are configured to be different sizes, but this is not limited to this, and each air flow guiding section may be provided in a rectangular or square shape of the same size, or the position and orientation of each air flow guiding section relative to the opening 11 may be interchangeable.

[0050] The shutter 30 is disposed inside the air outlet body 10 and serves to adjust the flow rate of conditioned air blown out from the air outlet body 10 . The shutter 30 is composed of a rectangular plate-like fixed part 31 and a movable part 32, each of which has a plurality of through holes 33 arranged at predetermined intervals in the longitudinal direction, and is configured to be arranged so that, with the fixed part 31 and the movable part 32 overlapping, the inside of the air outlet body 10 is divided into upper and lower parts at a position below the neck part 15 and above the air flow guide parts 21, 22. This shutter 30 is configured so that the movable part 32 can move in the longitudinal direction of the opening 11, which coincides with the direction in which the through holes 33 are arranged, relative to the fixed part 31 fixed to the air outlet body 10.

[0051] In other words, the shutter 30 is a well-known sliding shutter that enables adjustment of the flow rate of conditioned air by moving the movable part 32 relative to the fixed part 31 to change the degree to which the through holes 33 provided in each part overlap and communicate with each other, thereby changing the size (opening degree) of the opening portion through which conditioned air passes.

[0052] The movable part 32 of the shutter 30 is provided with an operating piece 34 that protrudes from its end toward the indoor space 90 (see FIG. 6). The user can adjust the opening degree of the shutter 30 by operating the operating piece 34 to move the movable part 32.

[0053] In detail, the user operates the operating piece 34 to move the movable part 32 to which the operating piece 34 is attached so as to shift it in the longitudinal direction of the opening 11 relative to the fixed part 31. This allows the opening degree of the shutter 30 to be freely adjusted between a fully open state (see Figures 7 and 9) in which the through holes 33 of the fixed part 31 and the movable part 32 completely overlap, maximizing the open area through which the harmonious air can pass, and a half-open state (see Figures 8 and 10) in which only part of the through holes 33 overlap, and the size of the open area is approximately half that of the fully open state.

[0054] Because the plate-like shutter 30 is disposed in an arrangement that traverses the inside of the air outlet main body 10, a part of the conditioned air flows along the shutter 30 as the conditioned air flows through each through-hole 33 of the shutter 30 toward each airflow guiding section 21, 22 inside the air outlet main body 10, and a part of this lateral velocity component remains in the airflow of the conditioned air that is blown out through the through-hole 33 and the airflow guiding sections 21, 22. The smaller the opening of the shutter 30, the greater the degree to which the conditioned air is guided laterally by the shutter 30, and the lateral velocity component in the airflow of the conditioned air also becomes relatively larger.

[0055] In this way, when the flow rate of the conditioned air is reduced by adjusting the opening of the shutter 30, the guiding influence of the shutter 30 becomes stronger, thereby increasing the lateral velocity component of the airflow of the conditioned air blown out from each airflow guiding section 21, 22, i.e., the horizontal velocity component, making it easier for the conditioned air to reach the window 70 even when the flow rate is low, and promoting the generation of an airflow of conditioned air that covers the window 70.

[0056] The first partition plate 41 is formed of a plate-like body and is arranged in the upper space 18 above the shutter 30 inside the air outlet body 10, in an orientation perpendicular to the longitudinal direction of the opening 11 in the air outlet body 10.

[0057] The first partition plate 41 is disposed at a predetermined position that divides the upper space 18 into two in the longitudinal direction of the opening 11 and overlaps with the arrangement range of the neck portion 15 in the air outlet body 10 (see Figs. 1 and 4).

[0058] The first partition plate 41 is disposed at a predetermined position closer to the window 70 than the longitudinal center position of the opening 11 in the upper space 18. Therefore, in the upper space 18, one region 19 that is distal to the window 70 from the first partition plate 41 is larger than another region that is proximal to the window 70 from the first partition plate 41.

[0059] The first partition plate 41 partially restricts the movement of the conditioned air in the upper space 18, more specifically, the movement of the conditioned air in the longitudinal direction of the opening 11. As a result, the conditioned air cannot proceed from one region to the opposite region separated by the first partition plate 41 in the upper space 18, and the conditioned air that enters the one region 19 passes through the shutter 30 and mainly heads toward the second airflow guiding section 22, while the conditioned air that enters the other region passes through the shutter 30 and mainly heads toward the first airflow guiding section 21. The first partition plate 41 is disposed to make the one region 19 larger than the other regions, and relatively increases the amount of conditioned air that enters the one region 19. As a result, the flow rate of the conditioned air blown out from the second airflow guiding section 22 is greater than the flow rate of the conditioned air blown out from the first airflow guiding section 21.

[0060] The second partition plate 42 is arranged in an orientation parallel to the longitudinal direction of the opening 11 in the air outlet body 10, in a region 19 of the upper space 18 inside the air outlet body 10, which is distal to the window 70 than the first partition plate 41.

[0061] The second partition plate 42 is disposed at a predetermined position where it divides the lower portion of the region 19 near the shutter 30 into two in the short direction of the opening 11 (see FIG. 4). In this way, the second partition plate 42 partially restricts the movement of the conditioned air in the region 19, so that the flow rate of the conditioned air passing through at least the shutter 30 toward the second airflow guiding section 22 is uniform in the short direction of the opening 11.

[0062] The airflow of conditioned air flowing into the air outlet body 10 from the neck portion 15 provided horizontally on the side of the air outlet body 10 attempts to travel straight through the upper space 18 including the region 19 toward the side opposite the side on which the neck portion 15 is located. However, by providing the second partition plate 42 below the region 19, only a portion of the conditioned air that enters the region 19 and passes over the top of the second partition plate 42 continues to travel straight, while the remainder is redirected by the second partition plate 42 and travels downward through the space between the side on which the neck portion 15 is located and the second partition plate 42.

[0063] This prevents adverse effects caused by bias of the conditioned air when the airflow of the conditioned air in the region 19 moves straight toward the side opposite to the side where the neck portion 15 is located. In other words, if the airflow of the conditioned air moves straight toward the side opposite to the side where the neck portion 15 is located in the region 19, the conditioned air changes direction at this opposite side and continues to move forward, and the conditioned air that is biased toward the opposite side moves from the region 19 to the second airflow guide section 22 through the shutter 30. As a result, the conditioned air reaches only a part of each guide vane 25 in the second airflow guide section 22, and the guide of the conditioned air flow by each guide vane 25 cannot be performed effectively, resulting in a situation where the conditioned air flow cannot be properly guided to its target position in the indoor space 90. The occurrence of such a situation can be prevented by using the second partition plate 42.

[0064] The decorative grill 50 is formed of an approximately plate-like body large enough to cover at least the opening 11 of the air outlet body 10, has a plurality of ventilation holes 51 arranged in a row, which are through holes that allow harmonious air to pass through, and is disposed at the end of the air outlet body 10 facing the indoor space.

[0065] The portion of the decorative grill 50 facing the opening 11 is formed in a lattice shape with a plurality of ventilation holes 51 regularly arranged, and a partition plate 26 separating the air flow guide sections 21, 22 is overlapped on the lattice part of the decorative grill.

[0066] The decorative grille 50 is configured so that its outermost periphery is in an upwardly raised state. Furthermore, a protruding piece 53 is formed on a part of the outermost periphery that protrudes outward from the opening 11.

[0067] This protruding piece 53 is attached to a known support frame 62 of a system ceiling (grid ceiling) assembled and arranged on the ceiling 60, either via a similarly known mounting plate or directly, so that the air outlet body 10 is fixed at a predetermined position on the ceiling 60, either alone or together with other ceiling-mounted equipment such as a lighting fixture 63 (see Figure 11).

[0068] This decorative grill 50 makes the inner air flow guide sections 21, 22 less visible from the indoor space 90 side, but since a large number of ventilation holes 51 of appropriate size are drilled and the opening rate of the decorative grill 50 is set to be sufficiently large, the conditioned air guided by the guide vanes 25 of the air flow guide sections 21, 22 can pass through without resistance and does not affect the blowing out of the conditioned air flow.

[0069] The shape of the ventilation holes 51 in the decorative grille 50 is not limited to the square shape shown in Figs. 2 and 11, but may be other shapes such as a polygon such as a rectangle or a hexagon, a circle, an ellipse, or the like.

[0070] Furthermore, the decorative grill 50 can be made to have the same appearance as the decorative grill in another air outlet device 100 for conditioning air to the interior zone that is installed on the ceiling 60, in which case it is possible to give the ceiling 60 a sense of unity in design.

[0071] Next, a description will be given of the state in which conditioned air is blown out from the air outlet device based on the above-mentioned configuration. It is assumed that conditioned air is continuously supplied to the air outlet device 1 through the duct 61.

[0072] The conditioned air supplied from the duct 61 enters the air outlet body 10 through the neck portion 15 on the side surface of the air outlet body 10 . Within the air outlet body 10 , the conditioned air first advances to the upper space 18 above the shutter 30 that traverses the inside of the air outlet body 10 .

[0073] The conditioned air that flows into the upper space 18 is guided by the first partition plate 41 arranged at a position overlapping with the arrangement range of the neck portion 15 of the air outlet main body 10, and is separated by this first partition plate 41 into one portion that enters one region 19 that is distal to the window 70, and another portion that enters another region that is proximal to the window 70. Then, in each region of the upper space 18, the conditioned air changes direction and heads toward the shutter 30 below.

[0074] At this time, in the first region 19, the second partition plate 42 is arranged to divide the lower part near the shutter 30 into two in the short direction of the opening 11. This second partition plate 42 further divides the conditioned air flow that has entered the region 19 into an air flow that flows downward between the side surface where the neck portion 15 is located and the second partition plate 42, and an air flow that flows downward between the side surface opposite to the side surface where the neck portion 15 is located and the second partition plate 42. As a result, the conditioned air that flows downward from the region 19 toward the shutter 30 is made to have an equal flow rate in the short direction of the opening 11. In this way, the second partition plate 42 prevents the conditioned air flow in the region 19 from proceeding straight from the neck portion 15 to the opposite side surface, resulting in a state in which the flow is biased to one part of the short direction of the opening 11.

[0075] In the upper space 18, the movement of the conditioned air in the longitudinal direction of the opening 11 is restricted by the first partition plate 41 and cannot proceed from one area to the area on the opposite side of the first partition plate 41, so that the conditioned air that enters the one area 19 heads directly toward a part of the shutter 30 located below the one area 19, and the conditioned air that enters the other area heads directly toward the other part of the shutter 30 located below the other area. Since the one area 19 is larger than the other areas, the flow rate of the conditioned air heading from the one area 19 toward the shutter 30 is greater than the flow rate of the conditioned air heading from the other areas toward the shutter 30.

[0076] The conditioned air guided by the first partition plate 41 and the second partition plate 42 and heading from each part of the upper space 18 toward the lower shutter 30 passes through the through hole 31 of the shutter 30 and heads toward the air flow guide sections 21, 22 located on the indoor space 90 side.

[0077] In addition, the shutter 30 is capable of adjusting the overlapping size of the through holes 33 of the fixed part 31 and the movable part 32 (opening degree of the shutter 30) by moving the movable part 32 relative to the fixed part 31 by operating the operating piece 34 from the indoor space 90 side. When the opening degree of the shutter 30 is made smaller than the fully open state, the flow rate of the conditioned air reaching each airflow guiding part 21, 22 through the through holes 33 of the shutter 30 decreases, while the degree to which the conditioned air is guided laterally by the shutter 30 increases, so that the lateral velocity component of the airflow of the conditioned air that has passed through the through holes 33 increases. This also has an effect on the airflow of the conditioned air that is finally blown out into the indoor space through the airflow guiding parts 21, 22, by increasing its horizontal velocity component.

[0078] The conditioned air that reaches the air flow guide sections 21, 22 through the through hole 31 of the shutter 30 travels between each of the guide blades 25 arranged at a predetermined interval, is guided by each of the guide blades 25, changes its direction in accordance with the inclination of the guide blades 25, and is then blown out into the indoor space 90 through the opening 11 and the holes 51 of the decorative grill 50.

[0079] At this time, in the first airflow guiding section 21 that is closer to the window 70, the airflow of conditioned air passing between each guide vane 25 proceeds along each guide vane 25 and is blown out diagonally downward into the indoor space 90. Due to the positional relationship between each guide vane 25 of the first airflow guiding section 21 and the neck portion 15, the airflow of conditioned air blown out through the first airflow guiding section 21 changes in its direction less at the opening 11 and can proceed without slowing down, resulting in an airflow with a high blowing speed. In addition, in the second air flow guide section 22 located distal to the window 70, the air flow of the conditioned air passing between each guide vane 25 advances along the guide vanes 25 and is blown out obliquely downward into the indoor space 90.

[0080] The airflow of conditioned air blown out through the second airflow guiding section 22 changes direction more in the opening 11 due to the arrangement of the guide vanes 25 of the second airflow guiding section 22 and the positional relationship with the neck section 15, and guidance by the second partition plate 42 in one area 19 of the upper space 18, so that the blowing speed is slower than in the case of the first airflow guiding section 21. On the other hand, due to the arrangement of the first partition plate 41 in the upper space 18 of the opening 11, a relatively large amount of conditioned air flows from the neck section 15 into the one area 19, and this conditioned air is guided mainly toward the second airflow guiding section 22 side, so that the amount of air blown out from the second airflow guiding section 22 is large.

[0081] The currents of conditioned air blown out from the air flow guiding portions 21, 22 of the opening 11 into the indoor space 90 advance within the indoor space without diffusing and approach the window 70. By setting the positional relationship between each guide vane 25 in each air flow guiding section 21, 22 and the neck portion 15 of the air outlet body 10, a difference in blowing speed is provided between the conditioned air blown out from the first air flow guiding section 21 and the conditioned air blown out from the second air flow guiding section 22.

[0082] In addition, by setting the position of the first partition plate 41 in the upper space 18 of the opening 11, the flow rate relationship between the conditioned air blown out from the first airflow guide section 21 and the conditioned air blown out from the second airflow guide section 22 is made appropriate.

[0083] As a result, the airflow of conditioned air from the first airflow guiding section 21 and the airflow of conditioned air from the second airflow guiding section 22, which are blown out at the same time, influence each other after being blown out, and depending on the temperature of the conditioned air, one may have a stronger influence on the other.

[0084] Specifically, in the case of cooling, the airflow of conditioned air blown out from the first airflow guiding section 21 significantly affects the airflow of conditioned air blown out from the second airflow guiding section 22. On the other hand, in the case of heating, the airflow of conditioned air blown out from the first airflow guiding section 21 and the airflow of conditioned air blown out from the second airflow guiding section 22 attract each other and remain in a state where they slightly change their traveling direction.

[0085] More specifically, in the case of cooling, the airflow of conditioned air blown out from the second airflow guiding section 22 on the distal side of the window 70 is cooled and has a high density. This airflow of conditioned air is drawn into the airflow blown out from the first airflow guiding section 21 on the proximal side, which has a higher blowing speed, and advances through the room with a larger horizontal velocity component toward the window side (see FIG. 13). Accordingly, excessive downward advancement of the low-temperature conditioned air blown out in a relatively large amount from the second airflow guiding section 22 due to the temperature difference (density difference) with the indoor air is suppressed, and a draft in the occupied area can be prevented. Note that, during cooling, the airflow of conditioned air blown out from the first airflow guiding section 21 is also drawn into the airflow of conditioned air blown out from the second airflow guiding section 22, and its advancement direction is slightly changed toward the direction toward one end of the longitudinal direction of the opening 11.

[0086] On the other hand, in the case of heating, the airflow of conditioned air blown out from the second airflow guiding section 22 on the distal side with respect to the window 70 is warm and has a low density. Unlike in the case of cooling, the proportion of this airflow of conditioned air that is drawn into the airflow blown out from the first airflow guiding section 21 on the proximal side, which has a faster blowing speed, is small (see FIG. 14). As a result, the airflow of conditioned air blown out from the first airflow guiding section 21 and the airflow of conditioned air blown out from the second airflow guiding section 22 attract each other, causing each of their traveling directions to slightly change toward the direction toward one longitudinal end of the opening 11.

[0087] In this way, the airflow of conditioned air blown out from the second airflow guiding section 22 proceeds within the room without being significantly influenced by the airflow blown out from the first airflow guiding section 21, and the relatively larger amount of high-temperature conditioned air blown out from the second airflow guiding section 22 is allowed to proceed further downward, improving the efficiency of air conditioning.

[0088] In the case of heating, the airflow of the conditioned air, which tends to rise, does not excessively stagnate along the ceiling 60 in the indoor space 90, but can smoothly reach the window 70 and spread out like a curtain. Also, in the case of cooling, the airflow of the conditioned air, which tends to descend, can be prevented from falling too far downward, and the conditioned air does not reach the living area below the indoor space between the air outlet and the window 70, ensuring that there is no adverse effect on the living area, such as a draft.

[0089] When the conditioned air current that has traveled through the indoor space 90 reaches the window 70, the current has a speed distribution that spreads in multiple directions relative to the window 70, and continues to travel downward and sideways so as to cover the window 70 like a curtain (see FIG. 16). In this way, the current of the conditioned air isolates the window 70 from the interior zone of the indoor space 90, and the impact of the external environment through the window 70 on the air conditioning in the interior zone is suppressed.

[0090] In this way, in the air outlet device according to this embodiment, a plurality of airflow guides 21, 22 are arranged in a row in the rectangular opening 11 of the air outlet body 10 provided in the ceiling 60, and the conditioned air that flows into the opening 11 of the air outlet body 10 is guided toward the window 70 by the guide vanes 25 in the airflow guides 21, 22 of the opening 11 and blown out, and each airflow blown out in a plurality of directions based on the different guide directions set for each airflow guide 21, 22 progresses through the indoor space toward the window 70. As a result, the conditioned air flow can be made to reach a wide area of ​​the window 70 from the air outlet position away from the window 70 without diffusing into the interior zone as much as possible, and a curtain-like airflow that covers the window 70 can be generated. This curtain-like airflow suppresses the influence of the external environment through the window 70, making it easier to maintain the air-conditioned state in the interior zone, and reducing the cost of air conditioning.

[0091] In the air outlet device according to the above embodiment, two air flow guiding sections 21, 22 are arranged at the opening 11 of the air outlet body 10, but this is not limited to this, and an appropriate number of air flow guiding sections can be arranged in accordance with the size of the air outlet device, particularly the size of the opening, which is selected based on conditions such as the arrangement of the air outlet in the indoor space and the volume and temperature of the conditioned air blown out from the air outlet.

[0092] Furthermore, in the air outlet device according to the above embodiment, the one direction in which the guide vanes 25 are arranged in the first air flow guiding section 21 and the other direction in which the guide vanes 25 are arranged in the second air flow guiding section 22, which have a significant influence on the direction of travel of the conditioned air blown out from each air flow guiding section 21, 22, are configured to be set in a direction tilted at a predetermined angle from the direction toward one longitudinal end of the opening 11, but this is not limited to this, and the direction in which the guide vanes are arranged in each of these air flow guiding sections may be set to an appropriate angle depending on the distance between the air outlet device and the exterior wall or window to which the conditioned air is to reach, the lateral size of the exterior wall or window to which the conditioned air is to reach, or each direction in which the air flow of each air flow guiding section is to be directed.

[0093] In addition, in the air outlet device according to the above embodiment, one direction in which the guide vanes 25 are arranged in the first air flow guiding section 21 is a direction inclined counterclockwise in FIG. 7 from the direction toward one longitudinal end of the opening 11, and the other direction in which the guide vanes 25 are arranged in the second air flow guiding section 22 is a direction inclined clockwise in FIG. 7 from the direction toward one longitudinal end of the opening 11. However, this is not limited to the above, and the direction in which the guide vanes are arranged in each air flow guiding section may be set to a direction inclined opposite to the longitudinal direction.

[0094] However, the positional relationship between the first air flow guiding portion and the neck portion is set so that one direction in which the guide vanes in the first air flow guiding portion are arranged is inclined toward the opposite side of the side of the air outlet body on which the neck portion is located, relative to the longitudinal direction of the opening, or more precisely, the direction toward which one longitudinal end of the opening faces.
