Description

  The present invention relates to an air conditioner including an air purifier, a dehumidifier, an air conditioner, and the like that include an air outlet and includes a louver for opening and closing the air outlet and changing the direction of the air.

In recent residences, the airtightness of the room has become higher, and air conditioning and temperature and humidity adjustments, as well as allergic diseases such as hay fever have spread widely.
Air conditioners such as air purifiers, dehumidifiers and humidifiers are widely used because of the growing need to remove allergens, dust, or odors from the air, or to maintain the temperature and humidity of the air appropriately. Among them, the air purifier takes in indoor air and removes fine particles in the air such as pollen and house dust and the smell of cigarettes and pets through the dust collection air filter and deodorizing air filter. It is discharged again indoors by a fan.

Furthermore, in addition to dust collection and deodorization, a water tank is provided inside, a humidifier that evaporates the water supplied to the tank and humidifies, and a humidifier and heat exchanger are provided to inhale high-humidity air. A dehumidifier that dehumidifies by absorbing moisture into the hygroscopic material, drying the air, heating and evaporating the hygroscopic material, and then condensing with a heat exchanger, and a multifunctional air purifier that integrates these functions There is also.
In such an air purifier, the air blowing direction is, for example, upward or forward depending on the function used, for example, when circulating the air in the entire installed room or when dehumidifying the laundry etc. Further, it is desirable to change the direction so as to be obliquely upward, and it is further desirable to use an electric type so that the blowing direction is automatically changed appropriately.

  Conventionally, for example, Japanese Patent Application Laid-Open No. 2000-283543 (Patent Document 1) has a link mechanism that connects a plurality of louvers and louvers that adjust an opening direction from the top surface direction to the rear surface direction and two or more surfaces and a blowing direction. It is disclosed. Japanese Patent Laid-Open No. 2008-96006 (Patent Document 2) includes a left-right louver that periodically operates between the expansion, parallelism, and concentration of the wind direction, and a vertical louver that changes the wind direction in the elevation direction. An apparatus for changing the wind direction of a dehumidifier is disclosed.

JP 2000-283543 A JP 2008-96006 A

  In such a louver of an air conditioner, the plurality of louvers have a rotation center that rotates with the air conditioner main body for each louver, and each of the louvers simply swings around it. A plurality of louvers are connected by a link mechanism so as to be linked to each other, and when the louver is rotated around the rotation center by operating a knob provided on one louver, the other louver is also rotated in conjunction with it. It is said.

  In the configuration as described above, each louver only rotates about the fulcrum of the louver, so in the horizontal direction of the wind that starts to open the louver from the closed state, the opening area of the air blow is small and the horizontal air volume is sufficiently blown Can not do it. Furthermore, when the louver is fully opened and the wind direction is upward, the tip of the louver protrudes upward from the upper surface of the air conditioner body.

  The present invention copes with the above-mentioned problems, and can sufficiently send the horizontal air flow that starts to open the louver, and when the louver is fully opened and is directed upward, the louver is lowered and most of the louver is blown. An object of the present invention is to provide an air conditioner that is housed inside a road and has a small amount of protrusion upward from the louver.

  The present invention provides an air conditioner having a wind direction changing mechanism provided at an outlet, wherein the wind direction changing mechanism includes a louver that changes an air blowing direction from the outlet, a first arm that moves the louver, and a second arm. The first arm is pivotally supported (first fulcrum) at the base end on the air conditioner body, and the louver is pivotally supported at the swing end (second fulcrum). The base end of the second arm is pivotally supported (third fulcrum) on the air conditioner body, and the louver is pivotally supported (fourth fulcrum) on the swing end. The wind direction changing mechanism includes a link mechanism connected by four fulcrums, the first fulcrum and the second fulcrum of the first arm, the third fulcrum of the second arm, and the fourth fulcrum. The louver moved by the link mechanism is Serial primarily characterized in that to operate the wind direction changes the oscillation end side of the second arm.

  According to the present invention, the wind direction changing mechanism includes a link mechanism that is connected by four fulcrums of the first fulcrum and the second fulcrum of the first arm, the third fulcrum of the second arm, and the fourth fulcrum. When the louver moving by the mechanism performs the air direction changing operation on the swing end side of the first and second arms, the horizontal blast can be sufficiently sent. In addition, the wind direction can be changed diagonally upward or upward, and when the louver is fully opened and the louver is turned upward, the louver is lowered, and most of the louver is stored in the air passage so that the louver is moved upward. The amount of protrusion can be reduced.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is a perspective view of an air conditioner according to the present invention, and FIG. 2 is a longitudinal sectional view.

  An operation panel 15 provided with various setting switches and the like is provided on the upper surface of the air conditioner body 1.

  An air filter 2 that adsorbs dust in the air is provided inside the air conditioner main body 1, and the air sucked from the intake hole 3 for sucking outside air is blown along the ventilation path 53 indicated by the arrow to be cleaned. Turn into. After the air exhausted from the air filter 2 passes through a heat exchanger 4 provided along with the air filter 2, moisture in the air is adsorbed to the dehumidifier 5 and dehumidified. The air dehumidified through the dehumidifier 5 is blown by a blower fan 7 that is rotationally driven by a motor 6, passes through a blower path 8, is deflected to a predetermined wind direction by a louver 9 of a wind direction changing mechanism, and then is released into the room. Is done.

  The louver 9 of the wind direction changing mechanism is provided at the air outlet of the air conditioner body 1, and can change the air blowing direction when the air outlet is opened and closed.

  The dehumidifier 5 contains a material having a moisture absorption function such as silica gel, for example. When the dehumidifier 5 is heated by the heating means 10, it releases moisture, and the heated and humid air containing moisture is converted into the heat exchanger 4. The air is cooled by exchanging heat with the low-temperature outside air that has passed through the air filter 2 and dehumidified by condensation of moisture.

  Part of the outside air that has passed through the heat exchanger 4 is configured to pass through the humidified air filter 11, and the lower end of the humidified air filter 11 is a water receiving tray 12 that is stored in the water tank 13 in the water receiving tray 12. By supplying water through the water supply path 66 by the water pump 14, moisture is supplied to the humidified air filter 12 to moisten the air. The moisture condensed in the heat exchanger 4 accumulates in the water tank 13.

  1 and 2, the louver 9 is shown in a closed state, and the upper surface of the louver 9 is positioned substantially flush with the shape of the upper surface 36 of the air conditioner body 1, and the air outlet on the upper surface of the air passage 8 is provided. It is in a closed state.

  FIG. 3 is a view in which the louver according to the present invention is moved from the closed position, and the upper surface of the air passage 8 is opened and air can be released upward as indicated by a broken line 9 ′ in FIG. is there.

  FIG. 4 is a longitudinal sectional view showing the configuration of the louver 9 of the wind direction changing mechanism when the air outlet is fully opened.

  As shown in FIGS. 4 and 3, the wind direction changing mechanism includes a louver 9 that changes the direction of air blowing from the outlet, a first arm 22 that moves the louver 9, and a second arm 23.

  The louver 9 includes a louver upper surface wind direction plate 16, a lower surface wind direction plate 17 and a central wind direction plate 18 provided substantially parallel to the upper surface wind direction plate 16, and a central wind direction between the upper surface wind direction plate 16 and the lower surface wind direction plate 17. A plate 18 is provided. In the space between the top wind direction plate 16 and the central wind direction plate 18, the direction of the arrow 20 (shown in FIG. 3) around fulcrums 19, 19 provided between the top wind direction plate 16 and the central wind direction plate 18. The auxiliary wind direction plate 21 is provided so as to be freely rotatable, and the user can change the wind direction to an arbitrary direction in the direction of the arrow 20.

  A pair of first arms 22 and second arms 23 are provided on both sides of one side surface and the other side surface of the louver so as to be substantially symmetrical, and one end (base end side) of the first arm 22 is an air conditioner body. 1 is pivotally supported by a fulcrum 24 (first fulcrum) provided at 1, and the other end (swinging end side) is swingable by a fulcrum 25 (second fulcrum) provided on the louver 9. It is pivotally supported.

  One end (base end side) of the second arm 23 is pivotally supported by a fulcrum 26 (third fulcrum) provided in the air conditioner body 1, and the other end (swing end side) is louvered 9. Is pivotally supported by a fulcrum 27 (fourth fulcrum) provided on

  Such a wind direction changing mechanism has a link mechanism that is connected to the first fulcrum and the second fulcrum of the first arm and the four fulcrum points of the third fulcrum and the fourth fulcrum of the second arm. The louver that moves by the mechanism changes the wind direction on the swing end side of the first and second arms. For this reason, the louver 9 operates differently from the wind direction changing operation that rotates at the fulcrum described in the conventional example. In other words, when the louver starts to open from the closed state, the louver operates to translate upward, so that a large opening area for blowing air in the horizontal direction is secured, and sufficient horizontal blowing is sent. Can do. Details will be described later.

  The length of the first arm 22, that is, the distance between the fulcrum 24 and the fulcrum 25 is larger than the length of the second arm 23, that is, the distance between the fulcrum 26 and the fulcrum 27. Is provided closer to the front surface of the air conditioner body 1 than the fulcrum 26.

  The first arms 22 provided on the left and right sides of the louver 9 are connected so as to rotate in synchronism with each other by a first connecting shaft 29 such as a steel wire or aluminum square on the fulcrum 25 side. The first arms 22 on both sides are configured to rotate around the fulcrum 24 in conjunction with each other.

  The second arms 23 provided on the left and right sides of the louver 9 are connected to each other by a second connecting shaft 30 such as a steel wire or an aluminum square on the fulcrum 27 side, and rotate in synchronization with each other. It is configured to transmit, and when the small motor 28 rotates, the second arms 23 on both the left and right sides are interlocked to rotate around the fulcrum 26.

  The first connecting shaft 29 is provided in the vicinity of the central wind direction plate 18 of the louver 9, and a first cover portion 32 having a shape in which a part of the central wind direction plate 18 surrounds the first connecting shaft 29 is provided. Prepare. The second connecting shaft 30 is provided close to the lower surface wind direction plate 17 of the louver 9, and a second cover portion 33 having a shape in which a part of the lower surface wind direction plate 17 surrounds the second connecting shaft 30 is provided. Prepare.

  When the louver 9 is viewed in the direction of the arrow 31 when the air passage 8 is opened with the louver 9 facing upward as shown in FIGS. 3 to 4, the first connecting shaft 29 and the second connecting shaft It is set as the structure which 30 cannot see directly.

  A first auxiliary spring 34 is provided at the fulcrum 24 of the first arm 22, and a second auxiliary spring 35 is provided at the second arm 23, the operation of which will be described later.

  Next, the operation of the wind direction changing mechanism including the louver 9 according to the present invention will be described with reference to FIGS.

  5, the louver 9 is closed in the same manner as FIGS. 1 and 2, and the air outlet plate 16 of the louver that is substantially flush with the upper surface 36 of the air conditioner body 1 closes the blowout port 8. It is sectional drawing which shows the state which is carrying out.

  FIG. 6 is a cross-sectional view showing a state in which air is blown toward the front surface of the air conditioner body 1.

  FIG. 7 is a cross-sectional view showing a state in which air is blown obliquely above the air conditioner body 1.

  FIG. 8 is a cross-sectional view showing a state in which air is blown upward.

  In FIGS. 5 to 8, the auxiliary wind direction plate 21 is omitted, and the left side is the front side of the air conditioner body 1 and the right side is the back side.

  When the louver 9 shown in FIG. 5 is closed, the fulcrum 25 between the first arm 22 and the louver 9 is on the right side of the fulcrum 24 and the fulcrum 27 between the second arm 23 and the louver is from the fulcrum 26. Is also arranged on the right side of the figure. The upper surface wind direction plate 16 forming the upper surface of the louver 9 is substantially parallel to the main body upper surface 36 and is flush with the upper surface 36.

  Here, when the small motor 28 is rotated in the direction of the arrow CCW, the fulcrum 27 moves in the direction of the arrow 37 perpendicular to the straight line 38 a connecting the fulcrum 26 and the fulcrum 27. The second arm 23 is on both sides of the louver 9, that is, on both sides of the front side and the back side of the sheet with the louver 9 in FIG. 5, and they are connected by the first connecting shaft 29 so that they are synchronized. Rotate.

  Since both the fulcrum 27 and the fulcrum 25 are provided on the louver 9, it may be considered that the fulcrum 25 is connected by a straight line 39 a on the louver 9, and the fulcrum 25 is orthogonal to a straight line 40 a connecting the fulcrum 25 and the fulcrum 24. Move in the direction of the arrow 41.

  Here, if the first auxiliary spring 34 is disposed so as to apply a rotational force that rotates in the direction of the arrow 42 around the fulcrum 24 to the first arm 22, the first auxiliary spring 34 is directed upward to support the weight of the louver 9 from below. Since a force is generated, the load torque of the drive motor 28 can be reduced by assisting the rotational force of the first arm 22 moving in the direction of the arrow 41, which is preferable.

A second auxiliary spring 35 is stretched on the second arm 23 at the spring fulcrum 50, and is pulled in the direction of arrow 43, whereby the second arm 23 is moved toward the arrow CCW (Counter).
It is preferable because the rotational force of the small motor 28 can be assisted by applying a rotational force in the (Clock Wise) direction.

  Here, the intersection 51a of the extended line of the straight line 38a and the straight line 40a is the instantaneous center of the movement of the louver 9 when the small motor 28 is rotated from the state of FIG. 5 and the second arm 23 is rotated in the arrow CCW direction. Thus, the louver 9 instantaneously rotates around the intersection 51a.

  That is, as described above, the straight line 39a is on the louver 9, but one end thereof is the fulcrum 25 of the first arm 22 and moves in the direction of the arrow 41 perpendicular to the straight line 40a. The other end of the straight line 39a is a fulcrum 27 of the second arm 23 and moves in the direction of an arrow 37 perpendicular to the straight line 38a. Since both the arrow 41 and the arrow 37 are orthogonal to the extension line to the intersection 51a, it can be considered that the straight line 39a, that is, the louver 9 is rotating around the intersection 51a. The center of the moment.

  Here, the intersection 51a, which is the instantaneous center of the rotational movement of the louver 9, is located in the space behind the back of the air conditioner body 1, so the louver 9 is as if outside the air conditioner body 1. Rotate around a virtual point.

  In the state shown in FIG. 6, the fulcrum 27 of the second arm 23 moves along the arcuate locus 44 to the positions of 38b, 39b, and 40b, and the straight lines 38a, 39a, and 40a connecting the fulcrums respectively. The state which made the wind direction board 16 substantially horizontal is shown.

  In this embodiment, the movement amount in the height direction of the fulcrum 27 when moving from the straight line 38a to the straight line 38b is h2, and the movement amount in the height direction of the fulcrum 25 when moving from the straight line 40a to the straight line 40b is h1. Then, h1> h2 is arranged, and the fulcrum 25 is arranged on the front side on the left side of the fulcrum 27 in the figure, so that the upper wind direction plate 16 of the louver 9 is on the left side in the figure on the front end 46 on the rear end. As a result, as shown in FIG. 6, the front end portion 46 is opened at a height H with respect to the upper surface 36 of the main body.

  Here, when the blower fan 7 is driven to rotate by the motor 6 and air is flown, the air is blown from the bottom to the top as indicated by an arrow 48 in the blower path 8. The air can be blown from the lower side along the upper surface wind direction plate 16, the lower surface wind direction plate 17, and the central wind direction plate 18, and blown forward in the direction of the arrow 49a, that is, horizontally.

  Here, if the height H of the portion where the front end portion 46 of the louver 9 rises and blows air is made smaller than the width W of the air blowing path 8, high-speed wind can be blown in the direction of the arrow 49a, that is, forward. Here, the instantaneous center of the louver 9 is an intersection 51b and is located in the vicinity of the rear portion of the upper surface of the louver 9.

  In the operation of the louver 9 from FIG. 5 to FIG. 6, the instantaneous center of the operation of the louver 9 is from the position of 51 a outside the air conditioner body 1 in FIG. 5 to the vicinity of the louver rear end portion 47 in FIG. Move to position 51b.

  This means that the distance between the louver 9 and the center of rotation is larger than the operation in which the louver 9 simply rotates around a point near the louver. Can be realized, that is, an operation that translates upward. Thereby, the opening area which ventilates with the wind direction of a horizontal direction can be ensured large, and the ventilation of a horizontal direction can fully be sent.

  This point will be further described with reference to FIG.

  FIG. 9 is a simplified cross-sectional view showing the operation of the louver 9, but it has a simple rotation center 52 in the vicinity of the louver 9 and the top wind direction plate 16 of the louver 9 is in the same closed position as shown in FIG. Assuming that the top wind direction plate 16 is opened to a horizontal position by rotating around the rotation center 52 by an angle Φ from the position 16a, the position is 160 indicated by a broken line in the figure, and the front end 46 is raised by a height H ′. However, since the amount of H ′ is small, air cannot be blown forward in this state.

  Here, when the same top wind direction plate 16b as shown in FIG. 6 is shown, the height of the front end portion 46 is H, and H> H ′. This indicates that the louver 9 is rising in addition to the rotational movement of the angle Φ, and the opening H through which air is sufficiently blown out can be obtained by moving upward.

  Since it operates as described above, when the air is blown forward, the top wind direction plate 16 is horizontal, and the height H ′ of the front end 46 is not too small, and the air is blown out appropriately. It can be.

  When the second arm 23 is further rotated in the arrow CCW direction, the state shown in FIG. 7 is obtained.

  Compared with the position of FIG. 5, the fulcrum 27 of the second arm 23 has moved along the arcuate locus 44 to the positions of the straight lines 38 a, 39 a, 40 a connecting the fulcrum to positions 38 c, 39 c, 40 c, respectively. .

  In this state, since the straight line 39c and the straight line 38c are substantially straight, the distance between the fulcrum 25 on the louver of the first arm 22 and the fulcrum 26 on the main body of the second arm 23 is the maximum.

  Therefore, the fulcrum 25 of the first arm 22 is at the most elevated position at this time, and the lift h3 of the fulcrum 25 takes the maximum value, and the second arm 23 is rotated even if the second arm 23 rotates in the vicinity of the position shown in FIG. Since the position of the fulcrum 25 of one arm 22 hardly changes, when the position of the fulcrum 27 of the second arm moves along the arc-shaped locus 44, the louver 9 rotates around the fulcrum 25 with little vertical movement. To perform the operation.

  Compared with FIG. 6, the front end portion 46 of the louver 9 rises and the angle turns obliquely upward, so that the air blown through the air passage 8 changes direction from the upward arrow 48 direction and obliquely upwards in the arrow 49b direction. Is blown out. Here, at the position where the straight line 39c and the straight line 38c are in a straight line, the instantaneous center of the louver 9 coincides with the position of the fulcrum 25, so that the louver 9 simply rotates around the fulcrum 25.

  When the second arm 23 is further rotated in the arrow CCW direction, the state shown in FIG. 8 is obtained.

  Compared with the position of FIG. 5, the fulcrum 27 of the second arm 23 has moved along the arcuate locus 44 to the positions of the straight lines 38 a, 39 a, 40 a connecting the fulcrum to positions 38 d, 39 d, 40 d, respectively. .

  In this state, the fulcrum 27 of the second arm 23 moves to the front side on the left side of the fulcrum 25 of the first arm 22 and further descends in the height direction to close the louver 9 shown in FIG. The position of the fulcrum 25 of the first arm 22 is also lowered.

  Then, the straight lines 38d, 39d, and 40d are shaped like a Z-shape as a whole, and the louver 9 is in a state in which the upper surface wind direction plate 16 faces in a substantially vertical direction, so that the air blown through the air passage 8 is an upward arrow. The air is blown upward in the direction of the arrow 49c while maintaining 48 directions.

  The instantaneous center 51 d of the straight line 39 d in the state of FIG. 8 is substantially near the fulcrum 24 of the first arm 22, and the louver 9 performs an operation of rotating about the fulcrum 24. Since the height of the louver 9 is lowered and most of the louver 9 is accommodated in the air passage 8, only the front end 46 protrudes from the main body upper surface 36 of the air conditioner main body 1 so as to protrude from the upper surface of the main body. The amount of protrusion is reduced.

  The second auxiliary spring 35 generates a rotational torque for rotating the second arm 23 in the direction of arrow CW via the spring fulcrum 50. This torque is moved from the state of FIG. 8 to the state of FIG. It is convenient because it is a power to assist.

  That is, by rotating the small motor 28 in the arrow CCW direction from the state shown in FIG. 5, the louver can be moved to the state shown in FIG. 8 via the states shown in FIGS. The air direction of the blown-out air shown can be changed from the front shown by the arrow 49a in FIG. 6 to the vertically upward shown by the arrow 49c in FIG. 8 through the diagonally upward shown by the arrow 49b in FIG.

  Conversely, by rotating the small motor 28 in the illustrated CW direction from the state shown in FIG. 8, the louver shown in FIG. 5 can be moved to the closed state via the states shown in FIGS. is there.

  Further, the small motor 28 is reciprocated so as to reciprocate between the state in which the wind direction shown in FIG. 8 is upward and the obliquely upward state shown in FIG. 7, or the forward blowing shown in FIG. It is possible to reciprocate between the front balloon and the diagonally upper balloon, or to reciprocate while changing the wind direction between the front balloon and the upper balloon.

  Needless to say, it is needless to say that the louver 9 can be stopped at each position shown in FIGS. 6, 7, and 8 to blow out air in a certain direction.

  Here, if a pulse motor is used as the small motor 28, it is preferable that the louver 9 can be held only by the detent torque (self-holding torque) of the pulse motor without being energized when stopped at any position. It is. Furthermore, even if the user wants to change the wind direction and manually moves the louver 9 in an arbitrary direction, the load is only the detent torque of the pulse motor, so that it can be easily moved.

  Next, the arrangement of the first connecting shaft 29 and the second connecting shaft 30 will be described. As described with reference to FIGS. 5 to 8, since the rotational force by the small motor 28 is transmitted to the left and right sides of the louver 9 via the second arm 23, the second arms 23 provided on the left and right sides of the louver 9 are synchronized. The second connecting shaft 30 is connected so as to rotate.

  It is desirable to connect the second arm 23 with a metal shaft made of aluminum or steel wire in order to make the second arm 23 thin. However, the rotational force can be transmitted.

  If the connecting shaft is provided at the fulcrum 26, the fulcrum 26 is a fulcrum between the second arm 23 and the air conditioner body 1, and the position is fixed. In addition, the air flow is obstructed and the air volume is reduced, and the metal shaft is visually observed by the user.

  On the other hand, if the second connecting shaft 30 is provided coaxially with the fulcrum 27 as shown in FIG. 4, the fulcrum 27 is a fulcrum between the louver 9 and the second arm 23, so the position is constant with respect to the louver.

  Therefore, the lower surface wind direction plate 17 is provided adjacent to the fulcrum 27 and the periphery of the metal second connecting shaft 30 can be covered with the second cover portion 33, so that the inside of the air passage 8 can be formed. Even if the second connecting shaft 30 is positioned, it can be a part of the louver 9 so that it does not obstruct the blowing and is not visually recognized by the user when the louver 9 is opened. This is convenient because it does not give a complicated impression due to the appearance of the mixed louver 9 and the metal drive shaft.

  Similarly, with respect to the first arm 22, the position of the fulcrum 25 is set to a position adjacent to the central wind direction plate 18, and the first connection shaft 29 is provided coaxially with the fulcrum 25 to surround the first metal connection shaft 29. Is covered with the first cover portion 32, and it is convenient that the user does not see the louver 9 when the louver 9 is opened without obstructing the air flow.

  An example of the operation of the air conditioner including the louvers described above will be described with reference to the flowchart shown in FIG.

  The louver 9 is in the closed position as shown in FIG. 5 (53). After the user starts operation (54) by pressing the power switch, the operation mode of the air conditioner is selected (55). The operation mode is selected from, for example, air cleaning (56), dehumidification (57), air blowing (58), or stirring (59) mode.

  Here, when the air cleaning (56) mode is selected, if the indoor air is blown upward, the small motor 28 is energized to move the louver 9 to the position shown in FIGS. Upward (60).

  When the dehumidification (57) mode is selected, the louver 9 is rotated from the position shown in FIG. 5 to the position shown in FIG. And diagonally upward (61).

  When the blow (58) mode is selected, the louver 9 is rotated from the position shown in FIGS. 5 to 6 to face forward (62). When the stirring (59) mode is selected, the louver 9 is moved from the position shown in FIG. 5 to the position shown in FIG. 8 and then reciprocally swung between the upward direction shown in FIG. 8 and the diagonally upward direction shown in FIG. The indoor air can be efficiently stirred by repeating the movement.

  After that, if the user presses the stop switch to give a stop instruction (64), each air conditioner stops operation in each mode and then rotates the louver 9 to move to the closed position shown in FIG. )

  In the present embodiment, an air cleaner and a dehumidifier are shown as the air conditioner. However, the present invention is not limited to these, and a blower, an air conditioner, a bathroom dryer, or a window-installed air conditioner may be used.

  Further, in this embodiment, the air passage is directed upward, the louver is in a horizontally long form, and the first arm 22 and the second arm 23 are both provided on the left and right side surfaces of the louver 9.
