Description

[Technical field]

[0001] The present invention relates to an air outlet device capable of switching the airflow direction of conditioned air that is blown out. [Background technology]

[0002] 2. Description of the Related Art Patent Documents 1 and 2 disclose inventions relating to air outlet devices that can switch the airflow direction of conditioned air that is blown out in order to realize air conditioning that meets the needs of occupants in a room.

[0003] Patent Document 1 describes a ceiling diffuser that includes an air outlet body 1 and an airflow adjustment body 2 that radially diffuses the airflow from the air outlet body 1 (see FIG. 1 of Patent Document 1). This ceiling diffuser includes a motor 3 that drives the airflow adjustment body 2 (cone) in the air hole axial direction A of the air outlet body 1, and a controller 7 that controls the drive of the motor 3 so that the airflow adjustment body 2 moves continuously and intermittently back and forth in the air hole axial direction A. The controller 7 controls the airflow adjustment body 2 to move in the tip direction (airflow direction) during heating so that the airflow does not stagnate on the ceiling surface due to buoyancy and reaches the floor surface sufficiently. Note that the opposite control is performed during cooling (see paragraphs 0007 and 0008 and FIG. 3 of the specification of Patent Document 1).

[0004] Meanwhile, Patent Document 2 describes an air outlet device that includes an airflow deflector 4 that protrudes into the open flow area on the inner periphery of the outer frame 2 upstream of the airflow guiding means (see FIG. 1 in Patent Document 2). This air outlet device deflects a part of the airflow that is about to proceed between the outer cone portion 2a and the airflow guiding means with the airflow deflector 4, guides the airflow to a corner of the open area of ​​the outer frame 2, and blows it out obliquely downward, thereby realizing oblique blowing from the corner (see Abstract of Patent Document 2). In addition, the inner cone 3 of the air outlet device is equipped with a vane body 3a arranged in a spread-out manner with four inclined surfaces facing the inner surface of the outer cone portion 2a, a support member 3b, and a lifting mechanism 3c that connects the vane body 3a to the support member 3b so that it can be raised and lowered (paragraph 0019 of the specification of Patent Document 2). [Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 2001-248887 A [Patent Document 2] JP 2004-003735 A Summary of the Invention [Problem to be solved by the invention]

[0006] However, the ceiling diffuser described in Patent Document 1 raises and lowers the airflow direction adjusting body 2 in the air hole axial direction A, i.e., in the vertical direction, so when switching between heating and cooling, the movement stroke of the airflow adjusting body 2 becomes long, and the movement time becomes long. In other words, it takes time to switch the airflow direction. In addition, since it is necessary to raise and lower the airflow adjusting body 2 in the vertical direction, the structure for switching the airflow blowing direction becomes complicated.

[0007] In addition, the air outlet device described in Patent Document 2 uses a lifting mechanism 3c to raise and lower the vane body 3a, but uses a temperature-sensitive actuator that changes its overall length in response to changes in the surrounding temperature within a predetermined temperature range (paragraph 0020 of the specification of Patent Document 2). Therefore, unless heating or cooling is performed, the vane body 3a of the middle cone cannot be raised and lowered. In addition, since the vane body 3a also needs to be raised and lowered in the vertical direction, the structure for switching the airflow blowing direction is complicated.

[0008] SUMMARY OF THE PRESENT EMBODIMENTS Accordingly, an object of the present invention is to provide an air outlet device having a simple structure and excellent operability and workability. [Means for solving the problem]

[0009] The air outlet device according to the present invention comprises: An air outlet device having a square anemometer-type air outlet and a chamber, The rectangular anemometer-type air outlet comprises an inner cone member, an outer cone member, a plate supported by a rotating shaft, and a baffle plate, The middle cone member includes a rectangular cylindrical base end and an expanded diameter portion that expands into a rectangular pyramid shape and communicates with the base end. The outer cone member is larger than the middle cone member and includes a rectangular cylindrical base end, a pyramidal truncated expanded diameter portion communicating with the base end, and a frame portion provided on a lower end periphery of the expanded diameter portion. The plate has a rectangular shape in a plan view and is provided at a center portion of the middle cone member, The baffle plate is flat and is provided on each of the four sides in a vertical position at the center of the boundary between the base end portion and the enlarged diameter portion of the intermediate cone member, The chamber is a box-shaped member having an air inlet and an open lower end, and is provided in such a manner that the opening at the lower end is connected to an upper end of the outer cone member, The inner cone member and the outer cone member are arranged concentrically, The rotating shaft has one end fixed to the back surface of the plate and the other end provided on the middle cone member so as to be concentric with the middle cone member and the outer cone member, which are arranged concentrically, and rotatably supports the plate; The lower end of the expanded diameter portion of the inner cone member (the lower end of the inner cone member) is positioned higher than the lower end of the frame portion of the outer cone member (the lower end of the outer cone member), and the plate is positioned lower than the lower end of the frame portion of the outer cone member (the lower end of the outer cone member).

[0010] (1) As a result, the conditioned air supplied from the duct to the air outlet device passes from the air inlet through the “inside of the middle cone member” and “between the middle cone member and the outer cone member.” The airflow that passes through the “inside of the middle cone member” is guided in the approximate direction of the corner of the lower end of the expanded portion of the middle cone member, where the air flow is not obstructed by the baffle plate, and the outlet airflow becomes an airflow blown out from the four corners.

[0011] (2) Furthermore, since the outlet airflow is strongly guided in the approximate direction of the angle of the lower end of the expanded portion of the middle cone member, where the air flow is not obstructed by this baffle plate, when the plate is in the 0° position, a horizontal airflow is generated blowing out from the approximate direction of the angle of the lower end of the expanded portion of the middle cone member, and when the plate is in the 45° position, a diagonally downward airflow is generated blowing out from the approximate direction of the angle of the lower end of the expanded portion of the middle cone member.

[0012] (3) Furthermore, the plate is positioned lower than the lower end of the frame portion of the outer cone member (in this description, sometimes simply referred to as the "lower end of the outer cone member"), and the lower end of the expanded portion of the inner cone member (in this description, sometimes simply referred to as the "lower end of the inner cone member") is positioned higher than the lower end of the outer cone member. Therefore, a certain gap (space) can be provided between the lower end of the inner cone member and the plate.

[0013] The air outlet device preferably includes a drive mechanism that rotates the plate by passing electricity through the rotation shaft.

[0014] Furthermore, the air outlet device is preferably configured to include a blower fan at the air inlet. Effect of the Invention

[0015] (1) With the air outlet device of the present invention, due to its configuration, the airflow that passes through the "inside of the middle cone member" is guided in the approximate direction of the corner of the lower end of the expanded portion of the middle cone where the air flow is not obstructed by the baffle plate, and the outlet airflow is an airflow that is blown out from the four corners. Therefore, even if multiple air outlet devices are arranged so that the edges of each device face each other on an office system ceiling, interference between the airflows blown out horizontally from adjacent air outlet devices can be suppressed, and discomfort felt by occupants can be reduced.

[0016] (2) When the plate is at the 0° position, the airflow blown out from the approximately angular direction of the lower end of the expanded diameter portion of the middle cone member is guided horizontally, and when the plate is at the 45° position, the airflow blown out from the approximately angular direction of the lower end of the expanded diameter portion of the middle cone member is guided diagonally downward. Therefore, by rotating the plate to the 45° position, for example, conditioned air can be supplied to a specific zone directly below the air outlet device, and air conditioning according to the needs of the people in this specific zone can be realized.

[0017] (3) Furthermore, since the plate is positioned lower than the lower end of the outer cone member and the lower end of the middle cone member is positioned higher than the lower end of the outer cone member, a certain gap (space) can be provided between the lower end of the middle cone member and the plate. When the plate is in the 0° position, the airflow passing through the “inside of the middle cone member” can be blown out horizontally without weakening its momentum.

[0018] In this way, the air outlet device of the present invention switches the airflow direction simply by rotating the plate, and compared to the switching mechanisms in conventional anemometer-type air outlet devices (for example, the mechanism that moves a cone up and down as described in Patent Document 1), operation is easier when rotating the plate manually, and a simple structure can be achieved when a drive mechanism for rotating the plate is provided, making it possible to provide an air outlet device with a simple structure and high operability and workability.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0020] The following describes an embodiment of the present invention in detail. The description of the components described below is an example (representative example) of an embodiment of the present invention, and the present invention is not limited to the following content unless the gist of the present invention is changed.

[0021] [Air outlet device 100] The configuration of an air outlet device 100 according to the present invention will be described with reference to FIGS. The air outlet device 100 has a square anemometer-type air outlet 10, a chamber 20, an air inlet 21 provided at the upper end of the chamber 20, and a neck 30 provided at the air inlet 21 (see FIG. 1).

[0022] [Square anemo type outlet 10] The square anemometer-type air outlet 10 is composed of an inner cone member 11, an outer cone member 12, a plate 14 supported by a rotating shaft 13, and a baffle plate 15 (see FIG. 3).

[0023] The middle cone member 11 is composed of a base end portion 111 having a rectangular cylindrical shape, and an expanded diameter portion 112 that is connected to the base end portion 111 and expands in the shape of a rectangular truncated pyramid. In this embodiment, the opening of the upper end 111t of the base end 111 of the middle cone member 11 (sometimes simply referred to as the "upper end 11t of the middle cone member 11" in this description) is square (see FIGS. 3 and 5). Since the base end 111 of the middle cone member 11 is a rectangular tube, the lower end of the base end 111 of the middle cone member 11 also has the same shape as the opening of the upper end 111t. In this embodiment, the enlarged diameter portion 112 of the middle cone member 11 is a square pyramid.

[0024] On the other hand, the outer cone member 12 is composed of a rectangular cylindrical base end portion 121, an expanded diameter portion 122 expanding into a quadrangular pyramid shape communicating with the base end portion 121, and a frame portion 123 provided on the periphery of a lower end 122b of the expanded diameter portion 122. The outer cone member 12 is one size larger than the inner cone member 11 (see FIG. 3). In this embodiment, the opening of the upper end 121t of the base end 121 of the outer cone member 12 (sometimes simply referred to as the "upper end 12t of the outer cone member 12" in this description) is square (see Figs. 3 and 5). In addition, since the base end 121 of the outer cone member 12 is a rectangular tube, the lower end of the base end 121 of the outer cone member 12 also has the same shape as the opening of the upper end 121t.

[0025] The plate 14 has a rectangular shape when viewed from above or below, and is provided in the center of the middle cone member 11 (see FIGS. 2, 3, and 5). In this embodiment, the plate 14 is square.

[0026] The baffle plate 15 is flat and is provided vertically at the center of the boundary between the base end portion 111 and the enlarged diameter portion 112 of the middle cone member 11 (see FIG. 3). Four baffle plates 15, 15a, 15b, 15c, and 15d, are provided on each of the four sides of the opening at the upper end 11t of the middle cone member 11 (see FIGS. 2, 3, and 5). In this embodiment, the baffle plates 15a to 15d are attached to the base end portion 111 of the middle cone member 11 (see FIG. 3).

[0027] [Chamber 20, Neck 30] The chamber 20 is a box-shaped member having an air inlet 21 and an open lower end, and is provided at the upper end 12t of the outer cone member 12 (see FIG. 3). The air inlet 21 is an opening for taking in conditioned air into the chamber 20, and in this embodiment, the chamber 20 has the air inlet 21 at its upper end. A neck 30 is provided at the air inlet 21 at the upper end of the chamber 20 (see FIG. 3), and a duct (not shown) that supplies conditioned air to the air outlet device 100 is connected to the neck 30. Therefore, in the case of a configuration including the neck 30 and the duct, the conditioned air from the duct is supplied from the air inlet 21 through the neck 30 into the chamber 20.

[0028] [Regarding the relative positions of each component] The inner cone member 11 and the outer cone member 12 are arranged concentrically (on the axis 60) (see FIG. 3). Therefore, a flow path for conditioned air is formed "inside the inner cone member 11" and "between the inner cone member 11 and the outer cone member 12." At this time, the conditioned air supplied from the duct connected to the neck 30 passes through the "inside of the middle cone member 11" and "between the middle cone member 11 and the outer cone member 12" from the air inlet 21. Here, the airflow that passed "inside the middle cone member 11" is distinguished as airflow 81, and the airflow that passed "between the middle cone member 11 and the outer cone member 12" is distinguished as airflow 82 (see FIG. 3).

[0029] The airflow 81 is blown out from the lower end 112b of the expanded diameter portion 112 of the middle cone member 11, but since the blowing in the side direction is blocked by the baffles 15a to 15d (see Figures 2 and 3), the airflow is strongly guided in the approximate angular direction of the lower end 112b of the expanded diameter portion 112 of the middle cone member 11, where the air flow is not blocked by the baffles 15a to 15d (see Figures 2 and 4).

[0030] On the other hand, air flow 82 is an air flow that flows obliquely downward in all directions including the side direction and the approximate angular direction (see FIGS. 2 to 4).

[0031] Since airflow 81 has a larger air volume than airflow 82 and is dominant, the conditioned air blown out from air outlet device 100 becomes an airflow (a composite airflow 83 shown by the dashed line in Figures 6 and 7) that is blown out in an approximately angular direction by combining the two.

[0032] In addition, the rotating shaft 13 has one end 13a provided on the back surface of the plate 14 (the surface facing the chamber 20), and the other end 13b is provided in the center of a fixing member 151 that is cross-shaped in a plan view and is attached to the upper end 11t of the middle cone member 11 so as to be concentric (on the axis 60) with the middle cone member 11 and the outer cone member 12 that are arranged concentrically, thereby rotatably supporting the plate 14 (see Figure 5).

[0033] As a result, when the rotating shaft 13 rotates, the plate 14 rotates horizontally. In the air outlet device 100, the plate 14 is configured to be rotated manually, and the rotation angle of the rotating shaft 13 (plate 14) is restricted to 0° to 45° by a protruding member 46 and an abutting member 47 that abuts against the protruding member 46 (see FIG. 5). In this embodiment, the protruding member 46 is a rod (stopper) attached to the rotating shaft 13, and the abutting member 47 is a plate member provided inside the middle cone member 11.

[0034] With this configuration, when manually rotating the plate 14, the rotation of the rotating shaft 13 (plate 14) can be stopped at a preset angle (in the range of 0° to 45°), so that conditioned air can be evenly blown out diagonally downward (see Figures 13 and 14) from the four corners of the lower end of the air outlet device 100, as described below.

[0035] In addition, when plate 14 rotates, the rotation does not stop at an angle (halfway position) other than the set angle (0° or 45°), improving the design. Note that rotation axis 13 shown in Figure 2 is shown for the sake of convenience in explaining the rotation of plate 14, and is not actually visible (the same applies to Figure 10).

[0036] The lower end 112b of the expanded diameter portion 112 of the inner cone member 11 (in this description, sometimes simply referred to as the "lower end 11b of the inner cone member 11") is positioned higher than the lower end 123b of the frame portion 123 of the outer cone member 12 (in this description, sometimes simply referred to as the "lower end 12b of the outer cone member 12"). In this embodiment, the distance d11 between the lower end 11b of the middle cone member 11 and the lower end 12b of the outer cone member 12 is 9 mm (see FIG. 3).

[0037] Moreover, the plate 14 is provided so as to be located below the lower end 12 b of the outer cone member 12 . In this embodiment, the distance d12 between the lower end 12b of the outer cone member 12 and the plate 14 is 4 mm (see FIG. 3).

[0038] Therefore, in this embodiment, the distance d10 between the lower end 11b of the middle cone member 11 and the plate 14 is 13 mm (see FIG. 3).

[0039] In this embodiment, the width s10 of the baffle plate 15 is 50 mm (see FIG. 3). The distance d13 between the lower end 15e of the baffle plate 15 and the plate 14 is 8 mm (see FIG. 3). The width s10 of the baffle plate 15 is set so as not to obstruct the passage (airflow passage) of air blown out from the four corners of the opening at the lower end 11b of the middle cone member 11 when the plate 14, which will be described later, is at a 45° position.

[0040] In this embodiment, the size of the opening at the upper end 11t of the middle cone member 11 is 150 mm×150 mm. That is, the length s21 of one side of the opening at the upper end 11t of the middle cone member 11 is 150 mm (see FIG. 5). On the other hand, the size of the opening at the lower end 11b of the middle cone member 11 is 210 mm×210 mm in this embodiment. That is, the length s20 of one side of the opening at the lower end 11b of the middle cone member 11 is 210 mm (see FIG. 2).

[0041] In this embodiment, the size of the opening at the upper end 12t of the outer cone member 12 is 207 mm×207 mm. That is, the length s31 of one side of the opening at the upper end 12t of the outer cone member 12 is 207 mm (see FIG. 5). On the other hand, the size of the opening at the lower end 12b of the outer cone member 12 is 265 mm×265 mm in this embodiment. That is, the length s30 of one side of the opening at the lower end 12b of the outer cone member 12 is 265 mm (see FIG. 2).

[0042] In this embodiment, the length s40 of one side of the plate 14 is 140 mm (see FIG. 2), and therefore the size of the plate 14 is 140 mm×140 mm.

[0043] [Operation of the air outlet device 100] (1. Plate position) Next, the operation of the air outlet device 100 according to the present invention will be further described with reference to Figures 6 to 14. Note that the same components as those already described are given the same reference numerals in the drawings, and detailed description thereof will be omitted. Furthermore, in a typical office system ceiling, the air outlet devices are often arranged so that the sides of the multiple air outlet devices face each other due to issues such as compatibility with lighting and appearance. Therefore, the following description will be given assuming that multiple air outlet devices are arranged and used in this manner on a system ceiling 70 (see FIG. 6).

[0044] (1-1. When the plate is at 0° position) In this description, when the plate 14 of the air outlet device 100 is in the position shown in FIG. 2, it is referred to as when the plate 14 is in the 0° position (when not rotated). As described above, the conditioned air blown out from the air outlet device 100 is formed by combining airflow 81 and airflow 82 to become combined airflow 83, which becomes a horizontal airflow blown out from the four corners of the lower end of the air outlet device 100 (see FIGS. 6 and 7).

[0045] In contrast, a conventional rectangular anemometer-type air outlet device does not have such a baffle plate 15, so the conditioned air blown out from the conventional rectangular anemometer-type air outlet device 300 is guided in the approximate direction of the side of the lower end of the middle cone member, and the blown-out airflow becomes a horizontal airflow blown out approximately from the side direction (see FIG. 8).

[0046] Therefore, when a conventional square anemometer-type air outlet device 300 is used in a similar arrangement for cooling operation, the airflow is set to be a horizontal airflow along the ceiling surface; however, depending on the arrangement of the air outlet devices 300, the airflows blown out horizontally from adjacent air outlet devices 300 may interfere with each other (see "interfering airflow 84" shown in FIG. 8) and continue to flow downward (towards the floor surface 71) (see FIG. 9), which may cause discomfort to people in the room ahead of this downward interfering airflow 84.

[0047] On the other hand, in the air outlet device 100 according to the present invention, the airflow is blown into the room from approximately the angular direction of the square anemometer-type air outlet 10 (see FIG. 6). Therefore, even if multiple air outlet devices 100 are arranged with their sides facing each other, interference between the airflows blown out horizontally from adjacent air outlet devices 100 is suppressed, thereby reducing the discomfort felt by occupants in the room (see FIG. 7). In addition, since interference between air currents blown out from a plurality of air outlet devices 100 can be suppressed, the space in the room that is not reached by the blown air currents can be reduced, making it possible to air-condition the room uniformly.

[0048] (1-2. When the plate is at a 45° position) In this description, when the plate 14 of the air outlet device 100 is rotated 45° from the position shown in FIG. 2 to the position shown in FIG. 10, this is referred to as the plate 14 being in a 45° position. In this way, by rotating the plate 45°, that is, so that the four corners of the plate 14 are respectively positioned near the centers of the four sides of the lower end 112b of the expanded diameter portion 112 of the middle cone member 11, the four corners of the plate 14 that overlapped the four corners of the lower end 112b of the expanded diameter portion 112 of the middle cone member 11 rotate and move, and passages (air flow passages 85) for the blown out air are formed at the four corners of the opening of the lower end 11b of the middle cone member 11 (see Figure 10).

[0049] Furthermore, even if the plate 14 is rotated 45°, the baffles 15a to 15d are provided on each of the four sides in a vertical position at the center of the boundary between the base end 111 of the middle cone member 11 and the expanded diameter portion 112, so that the airflow 81 is strongly guided in the approximate angular direction of the lower end 112b of the expanded diameter portion 112 where the air flow is not blocked by the baffles 15a to 15d (see Figures 10 to 12).

[0050] On the other hand, the air flow 82 is guided diagonally downward due to the positional relationship between the expanded diameter portion 112 of the middle cone member 11 and the expanded diameter portion 122 of the outer cone member 12 (see Figures 10 to 12), and the air flow 81 is guided horizontally by the plate 14 and immediately thereafter is guided diagonally downward by the air flow passage 85 (see Figures 10 and 12). In this case, airflow 81 is dominant in terms of both airflow strength and air volume, and therefore a composite airflow 83 of airflow 82 and airflow 81 from air outlet device 100 becomes an outlet airflow (composite airflow 83 shown by dashed lines in Figures 13 and 14) that is blown out strongly diagonally downward compared to when plate 14 is in the 0° position (see Figures 6 and 7).

[0051] Therefore, for example, conditioned air can be supplied to a specific zone (an area of ​​1800 mm x 1800 mm in this embodiment) directly below the air outlet device 100, thereby realizing air conditioning according to the needs of the occupants in this specific zone.

[0052] (2. Effects of the relative positions of each component) Next, the effects and advantages of the positional relationship of each component of the air outlet device 100 according to the present invention will be described with reference to FIGS.

[0053] (2-1. Regarding the air outlet device 100) As described above, the lower end 11b of the inner cone member 11 is provided so as to be located higher than the lower end 12b of the outer cone member 12. The plate 14 is provided so as to be located lower than the lower end 12b of the outer cone member 12. Therefore, a certain gap (space) can be provided between the lower end 11b of the middle cone member 11 and the plate 14. In this embodiment, this certain gap (distance d10) is 13 mm (see FIG. 2). Therefore, when the plate 14 is at the 0° position, the air outlet device 100 can blow out the airflow 81 in the horizontal direction.

[0054] (2-2. Regarding the air outlet device 101) If the plate 14 is positioned at the same height as the lower end 12b of the outer cone member 12 or higher than the lower end 12b of the outer cone member 12, the airflow 81 will collide with the plate 14 and be blown out horizontally at a higher position than if the plate 14 were positioned lower than the lower end 12b of the outer cone member 12.

[0055] For example, the air outlet device 101 is configured such that the plate 14 is positioned at the same height as the lower end 12b of the outer cone member 12 (see FIG. 15). With such a configuration, the airflow 81 is blown out in the horizontal direction at a higher position, and collides with the frame portion 123 of the outer cone member 12, weakening the component guiding it in the horizontal direction.

[0056] (2-3. Regarding the air outlet device 102) Contrary to the air outlet device 101, if the plate 14 is positioned extremely lower than the lower end 12b of the outer cone member 12, the air flow 81 flows horizontally after colliding with the plate 14, but since the enlarged diameter portion 112 of the middle cone member 11 and the plate 14 are separated from each other, the horizontal guidance component is weakened.

[0057] For example, the air outlet device 102 is configured such that the plate 14 is positioned extremely below the lower end 12b of the outer cone member 12 (see FIG. 16). With such a configuration, the horizontal guide component of the airflow 81 is weakened, so that the airflow 81 is blown out further downward compared to the air outlet device 100.

[0058] On the other hand, the air outlet device 100 of the present invention has an appropriate gap between the lower end 12b of the outer cone member 12 and the plate 14, which prevents the air flow 81 from colliding with the frame portion 123 of the outer cone member 12 and prevents the horizontal guidance component of the air flow 81 from becoming weak.

[0059] (2-4. Regarding the air outlet device 100) Furthermore, since the air outlet device 100 is configured so that the lower end 11b of the middle cone member 11 is positioned higher than the lower end 12b of the outer cone member 12, a certain gap (distance d10) can be provided between the lower end 11b of the middle cone member 11 and the plate 14, while the plate 14 is not positioned extremely lower than the lower end 12b of the outer cone member 12, thereby preventing damage during transportation and improving design.

[0060] For example, if the lower end 11b of the middle cone member 11 is located at the same height as the lower end 12b of the outer cone member 12, in order to provide a certain gap (distance d10, 13 mm in this embodiment) between the lower end 11b of the middle cone member 11 and the plate 14, the plate 14 needs to be positioned further below the lower end 11b of the middle cone member 11, which is located at the same height as the lower end 12b of the outer cone member 12. Specifically, if the lower end 11b of the middle cone member 11 is configured to be located at the same height as the lower end 12b of the outer cone member 12, the plate 14 needs to be positioned 13 mm below the lower end 11b of the middle cone member 11 (the lower end 12b of the outer cone member 12).

[0061] In this case, the plate 14 is positioned too far below the lower end 12b of the outer cone member 12, and there is a risk that the plate 14 positioned too far below (protruding downward) may collide with something and be damaged during transportation. In addition, the appearance is also unattractive.

[0062] In addition, by providing a distance d13 between the lower end 15e of the baffle plate 15 and the plate 14, even when the plate 14 is at a 45° position, a small amount of conditioned air can be blown out from the gap between the plate 14 and the baffle plate 15 toward the approximate side direction of the opening at the lower end 11b of the middle cone member 11. Therefore, during cooling, it is possible to prevent indoor air from coming into contact with the vicinity of the center of the side of the opening at the lower end 11b of the middle cone member 11 and causing condensation.

[0063] As described above, the size of the plate 14 is slightly smaller than the size of the opening at the upper end 11t of the middle cone member 11. As a guideline, by setting the ratio of the area of ​​the plate 14 to the opening at the upper end 11t of the middle cone member 11 at 85% to 90%, a horizontal airflow can be generated when the plate 14 is at the 0° position, and an airflow passage 85 can be secured to generate an obliquely downward airflow when the plate 14 is at the 45° position. On the other hand, if the size of the plate 14 is made much smaller than the size of the opening at the upper end 11t of the middle cone member 11, the amount of airflow 81 that collides with the plate 14 when the plate 14 is at the 0° position decreases, and it becomes impossible to generate a horizontal airflow. On the other hand, if the size is made larger, the airflow passage 85 becomes narrow when the plate 14 is at the 45° position, and it becomes impossible to blow the airflow diagonally downward.

[0064] [Air outlet device 200] The air outlet device 200 includes the configuration of the air outlet device 100, and further includes a drive mechanism 40 and a blower fan 50 (see FIG. 17).

[0065] [Drive mechanism 40] The driving mechanism 40 rotates the plate 14 by applying electricity via the rotating shaft 13 . Since the air outlet device 200 can rotate the plate 14 by the drive mechanism 40, the airflow can be automatically switched as described above, and the airflow can be switched remotely by sending a predetermined control signal. This eliminates the need for manual work at high altitudes (the work of rotating the plate 14), and even if the air outlet device 200 is placed at a height that cannot be reached without a stepladder, the airflow can be switched easily and safely.

[0066] (1. Motor) In this embodiment, the air outlet device 200 uses a motor 41 that rotates the rotary shaft 13 as the drive mechanism 40 (see FIG. 17). The air outlet device 200 also includes a cam 42 provided on the rotary shaft 13, and a limit switch 43 engaged with the cam 42. The motor 41, the cam 42, the limit switch 43, etc. are attached by a box-shaped support member 44, an L-shaped support member 45, etc. for providing them inside the chamber 20.

[0067] When a motor 41 is used as the drive mechanism 40, airflow switching in a conventional anemometer-type air outlet requires a mechanism for converting the rotational motion of the motor into linear motion. However, the air outlet device 200 only requires the motor 41 to rotate the plate in the range of 0° to 45°, so airflow switching can be achieved with a simple structure without the need for a complex mechanism. In addition, the time it takes for the motor 41 to operate, i.e., the time it takes for the plate 14 to rotate and switch the airflow, can be shortened, thereby reducing power consumption and achieving ease of use that satisfies the user (those occupying the room).

[0068] Note that motor 41 only needs to have the function of rotating plate 14 (and rotating shaft 13 supporting plate 14), and does not need any complicated functions, so motor 41 installed inside air outlet device 200 (inside chamber 20) can be made compact. Therefore, motor 41 does not press against the flow path inside air outlet device 200, and pressure loss and noise generation can be reduced.

[0069] Furthermore, with a configuration including a cam 42 and a limit switch 43, the rotating shaft 13 and the cam 42 attached thereto are rotated by the motor 41, and at this time, the contacts of the limit switch 43 engaged with the cam 42 open and close, making it possible to detect that the rotating shaft 13 and the cam 42 have rotated a certain angle (e.g., 45°). Therefore, when it is detected that the rotating shaft 13 and cam 42 have rotated a certain angle, the rotation of the rotating shaft 13 by the motor 41 is stopped, so that the plate 14 can be rotated at any angle (for example, in the range of 0° to 45°).

[0070] Specifically, Fig. 18(i) shows the state when the plate 14 is at the 0° position, and (ii) shows the state when the plate 14 is at the 45° position, but when the rotating shaft 13 and cam 42 rotate a certain angle (45°) in the direction of the arrow from the state shown in Fig. 18(i), the contacts of the limit switch 43b close, detecting that the certain angle has been rotated (see the dashed frame in Fig. 18(ii)). This detection is used as a trigger to stop the rotation of the rotating shaft 13 by the motor 41, thereby stopping the rotation of the plate 14 at the 45° position.

[0071] In addition, the motor 41 is a motor that can switch the direction of rotation between forward and reverse. Therefore, when changing the position of the plate 14 from 45° to 0°, the direction of rotation of the motor 41 is switched, so that the rotating shaft 13 and the cam 42 rotate in the direction opposite to the direction of the arrow shown in Fig. 18(i), the contacts of the limit switch 43a close, and the rotation of the rotating shaft 13 by the motor 41 is stopped at the timing when it is detected that the rotating shaft 13 has rotated a certain angle in the opposite direction (see the dashed frame in Fig. 18(i)).

[0072] (2. Rotary solenoid) Also, a rotary solenoid can be used as the drive mechanism 40 instead of the motor 41. The rotary solenoid performs reciprocating rotational motion in a certain angular range, and can rotate the rotating shaft 13 in a certain angular range (for example, 0° to 45°). By passing electricity through the rotary solenoid, it rotates at a pre-specified angle (45° in this embodiment) by the electromagnetic force of the built-in coil and the permanent magnet, and the position after rotation is maintained even if the current is cut off. Also, the rotary solenoid rotates in the reverse direction by changing the direction of current flow, and stops when it returns to the 0° position. In this way, by using a rotary solenoid, the rotation angle of the plate 14 can be set without the need for the cam 42 and the limit switch 43, so that the device can be made more compact.

[0073] [Ventilation fan 50] The air outlet device 200 is provided with a blower fan 50 at the air inlet 21 at the upper end of the chamber 20 (see FIG. 17). With this configuration, construction of a duct is not required, and the air outlet device 200 can be installed in a ductless space. In addition, when air conditioning is not required, the supply of conditioned air can be stopped by stopping the blower fan 50, so that air conditioning can be realized in accordance with the needs of the occupants.

[0074] The air outlet devices 100 and 200 described above are examples of the air outlet devices according to the present invention, and the configuration of the present invention is not limited to these examples without departing from the spirit of the present invention. For example, the positional relationship between the lower end 11b of the middle cone member 11, the lower end 12b of the outer cone member 12, and the plate 14 can be appropriately modified in design as long as the functional effects of the positional relationship described above can be achieved. [Industrial Applicability]
