The present invention relates to a wind direction changing device and an air conditioner including the same.

Patent Document 1 discloses a wind direction changing device installed at an air outlet of an air conditioner for changing the wind direction to the left or right.

Japanese Unexamined Patent Publication No. 2009-74731 (published on April 9, 2009)

However, the wind direction changing device disclosed in Patent Document 1 has the following problems. This problem will be described with reference to FIGS. 20 and 21.

FIG. 20 is a top view showing a schematic configuration of a wind direction changing device installed at an air conditioner outlet, which is shown as a reference example, FIG. 21 is a view corresponding to FIG. 20, and FIG. 20A is a drive. It is a schematic diagram which shows the arrangement of the wind direction plate in the state which the arm does not swing, and (b) is the schematic diagram which shows the arrangement of the wind direction plate when the drive arm swings.

Explaining with reference to these figures, the wind direction changing device 201 includes a plurality of wind direction plates 205. One end of each of the plurality of wind direction plates 205 is fixed so as to be spaced apart from each other in the longitudinal direction of the substrate 207, and the other end is connected to the interlocking plate 212. A motor (not shown) is installed on the back side of both ends of the substrate 207 in the left-right direction, and the drive arm 209 is connected to the motor. When the drive arm 209 swings, the connecting plate 212 swings accordingly, and the wind direction plate 205 can be changed from the arrangement shown in FIG. 21 (a) to the arrangement shown in FIG. 21 (b).

By the way, in the wind direction changing device 201, when the wind direction plates 205 located at both ends of the air outlet approach the side wall surface 215 in the vicinity of the side wall surface 215 of the air outlet (not shown) provided in the housing, the flow path becomes narrow. Become. Therefore, the wind emitted from the air outlet receives resistance from the side wall surface 215 of the wind direction changing device 201. As a result, not only the amount of wind blown from the entire outlet is reduced, but also a vortex (turbulent flow) may be generated in the circled portion in FIG. When such a vortex is generated, the air flow becomes unstable near the side wall surface 215 of the outlet, and as a result, a state in which the wind normally flows from the outlet and a state in which the wind flows backward alternately occur, a surging phenomenon. May occur.

Further, when a backflow of wind occurs, warm and moist outside air may flow back and enter from the air outlet near the side wall surface 215 of the air conditioner (not shown). However, for example, when the air conditioner is cooled, cold air is blown out from the air outlet, so that the backflowing moist air is cooled by the cold air, and there is a possibility that dew condensation occurs on the side wall surface 215 of the air outlet.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a wind direction changing device capable of suppressing the occurrence of surging phenomenon and the occurrence of dew condensation on the side wall surface of the air outlet of an air conditioner. The purpose is to realize an air conditioner equipped with this.

In order to solve the above problems, in the wind direction changing device according to one aspect of the present invention, each of the plurality of wind direction plates has one end of the plurality of wind direction plates on the air blowing side in the longitudinal direction of the substrate. A plurality of wind direction plates supported by the substrate at intervals in the longitudinal direction of the substrate to control the blowing direction of air-conditioned air so as to swing along the substrate, and one of the plurality of wind direction plates. An interlocking plate having a plurality of locking portions for locking the plurality of wind direction plates with play so that each of the ends swings along the longitudinal direction, and the interlocking plate. It has a drive unit that swings along the longitudinal direction, and the end on the air introduction side opposite to the one end of the wind direction plate is fixed to the substrate and at least on both ends in the longitudinal direction. the size of the play of the one end and the opposite end is the wind direction plate fixed on the substrate, the other much larger than the size of the play of the wind direction plate, the play is given a driving force The point of action of the interlocking plate that works is the distance that it moves until it comes into contact with one of the wind direction plates and starts moving one of the wind direction plates, and is supported by the substrate at least on both ends in the longitudinal direction. The distance corresponding to the wind direction plate is larger than the distance corresponding to the other wind direction plates .

According to one aspect of the present invention, the wind direction plates supported by the substrate at least on both ends in the longitudinal direction of the substrate are locked by play having a size different from that of other wind direction plates. Therefore, there is a difference in the positional relationship between the wind direction plate and the interlocking plate due to the swing of the interlocking plate. This has the effect of causing a difference in the wind direction depending on the wind direction plate.

7 is a perspective view showing the external shape of the wind direction changing device shown in FIGS. 4 to 6, and FIG. 8 is a view corresponding to FIG. 7 and shows a part of the wind direction changing device in an enlarged manner. It is an exploded perspective view, FIG. 9 is a view corresponding to FIG. 8, and is a perspective view showing a part of the wind direction changing device in a further enlarged manner, and FIG. 10 is an enlarged view of the wind direction plate shown in FIG. It is a side view, FIG. 11 is a view corresponding to FIG. 10, is a plan view of a wind direction plate, and FIG. 12 is a plan view of an interlocking plate shown in FIG. 7.

Explaining with reference to these figures, the wind direction changing device 12 includes a substrate 33, a first wind direction plates 34 and 36, a plurality of second wind direction plates 35 and 37, and a first interlocking plate 44. A second interlocking plate 45, a first drive arm 52, a second drive arm (not shown), and first and second motors (drive units) provided at both ends on the back side of the substrate 33. It has 47 and 48.

In the present specification, the first wind direction plate means a wind direction plate supported by the substrate on both ends in the longitudinal direction of the substrate, and the second wind direction plate means all the wind directions other than the first wind direction plate. It shall mean a board.

Further, in the present specification, the words "first" and "second" for each member other than the first wind direction plate and the second wind direction plate change the wind direction when the wind direction changing device is viewed from the front. Means "right side" and "left side" of the device.

In the present embodiment, as shown in FIG. 7, a group of wind direction plates described later is formed from one first wind direction plate and four second wind direction plates. In the present embodiment, the first wind direction plate refers to the first wind direction plates 34 and 36 supported by the substrate 33 on both ends in the longitudinal direction of the substrate 33, but the present invention is not limited to this. The first wind direction plate may include a plurality of wind direction plates supported by the substrate 33 on each of both ends in the longitudinal direction of the substrate 33.

Further, in the present embodiment, the first wind direction plates 34 and 36 and the second wind direction plates 35 and 37 are different except that they are arranged on the end side with respect to the substrate 33. The basic structure of is common. However, for convenience of explanation, these wind direction plates are designated by different reference numerals in the present specification.

In the present embodiment, each of the first wind direction plates 34, 36 and the plurality of second wind direction plates 35, 37 are supported by the substrate 33 in the longitudinal direction of the substrate 33 so as to be spaced apart from each other. Each controls the direction in which the conditioned air is blown out.

As shown in FIG. 7, the first drive arm 52 is provided on the right side of the substrate 33 when the wind direction changing device 12 is viewed from the front side. The first drive arm 52 is connected to a first motor 47 provided on the right end side of the substrate 33 via a first reduction gear (not shown), and is connected along the longitudinal direction of the substrate 33. It is configured to be swingable.

On the other hand, the second drive arm (not shown) is provided on the left side of the substrate 33 when the wind direction changing device 12 is viewed from the front side as shown in FIG. 7. The second drive arm is connected to a second motor 48 provided on the left end side of the substrate 33 via a second reduction gear (not shown), and swings along the longitudinal direction of the substrate 33. It is configured to be movable.

In addition, in this specification, "swing along the longitudinal direction" is not only a form of linearly reciprocating along the longitudinal direction of the substrate 33, but also a form of rotating in an arc shape along the longitudinal direction of the substrate 33. May also be included. More specifically, in the configuration examples shown in FIGS. 7 to 9, the movement of the first drive arm 52 rotating in an arc along the longitudinal direction of the substrate 33 (arc-shaped circular motion) is interlocked to be described later. It is transmitted to the first wind direction plate 34 and the plurality of second wind direction plates 35 via the plate 44. As a result, as shown in FIG. 11, for example, one end of the first wind direction plate 34 rotates in an arc shape along the longitudinal direction of the substrate 33 in conjunction with the rotation of the first drive arm 52. The arc-shaped rotation along the longitudinal direction has a component of rocking along the longitudinal direction and a component of rocking along the direction orthogonal to the longitudinal direction. However, the width of the swing along the longitudinal direction is larger than the width of the swing along the direction orthogonal to the longitudinal direction. Therefore, the main movements of the first drive arm 52, the interlocking plate 44, the first wind direction plate 34, and the plurality of second wind direction plates 35 can be expressed as "swing along the longitudinal direction". The above description of "swing along the longitudinal direction" applies to all specific examples of the present application.

A first pin 55 and a second pin (not shown) are provided near the tip of each of the first drive arm 52 and the second drive arm. Further, the first interlocking plate 44 and the second interlocking plate 45 have a first connecting opening 58 and a second interlocking opening 58 and a second interlocking plate 45 which can be engaged with the first pin 55 and the second pin at one end of each. A connecting opening (not shown) is provided by engaging the first pin 55 and the first connecting opening 58, and the second pin and the second connecting opening with each other. The first drive arm 52 and the second drive arm can be swung to swing the first interlocking plate 44 and the second interlocking plate 45 along the longitudinal direction of the substrate 33, respectively.

In the present embodiment, the first and second wind direction plates 34 to 37 are the right side wind direction plate group 65 located on the right half of the substrate 33 and the left side located on the left half of the substrate 33 as shown in FIG. It is divided into a wind direction plate group 66, and each wind direction plate group 65 and 66 can be controlled independently. In the present embodiment, the right side wind direction plate group 65 and the left side wind direction plate group 66 have the same configuration except that the arrangement with respect to the substrate 33 is different. Therefore, in the following, the configuration of the right wind direction plate group 65 will be mainly described.

First, the first and second wind direction plates 34 and 35 according to the present embodiment will be specifically described with reference to FIGS. 7 to 11 again.

(Wind direction plate)
Explaining with reference to these figures, the first wind direction plate 34 (hereinafter, also simply referred to as “wind direction plate 34”) mainly supports the blade portion 71 (see FIGS. 9 and 10) and the blade portion 71. It is provided with a connecting portion 81 erected on the substrate 33 (see FIG. 7 and the like). In the present embodiment, the connection portion 81 is fixed to the substrate 33, so that one end of the first wind direction plate 34 is supported by the substrate 33 so as to swing along the longitudinal direction of the substrate 33. The blade portion 71 is composed of a hard portion 73 and a soft portion 78 formed on one side portion of the hard portion 73 and connected to the connecting portion 81. The connecting portion 81 is formed so that the rising direction from the substrate 33 is parallel or substantially parallel along the boundary line between the hard portion 73 and the soft portion 78. Further, the boundary line between the soft portion 78 and the connecting portion 81 serves as a base axis for the soft portion 78 to rotate (that is, swing) in an arc shape along the longitudinal direction. As a result, the blade portion 71 of the first wind direction plate 34 can swing as shown in FIG.

The hard portion 73 includes a support shaft opening 74 provided so as to penetrate the plane of the hard portion 73. In the support shaft opening 74, the peripheral wall on the substrate 33 side is provided with a first support shaft (support portion) 75 projecting inward from the peripheral wall of the support shaft opening 74. The protruding direction (axial direction) of the first support shaft 75 is parallel to the protruding direction (axial direction) of the first pin 55, and is also parallel to the rising direction of the connecting portion 81. The first support shaft 75 rotatably supports the interlocking plate 44, which will be described in detail later, and has play in the first opening 69 (locking portion) provided on the flat surface of the interlocking plate 44. Is locked.

A first flange portion 76 and a second flange portion 77 are provided on both ends in the axial direction of the first support shaft 75. In the present embodiment, by arranging the interlocking plate 44 (see FIG. 7 and the like) between the first flange portion 76 and the second flange portion 77, the interlocking plate 44 is removed from the first support shaft 75. It prevents the interlocking plate 44 from coming into direct contact with the peripheral wall of the support shaft opening 74. Further, by arranging in this way, it is possible to prevent the interlocking plate 44 and the drive arm 52 from coming into direct contact with each other, and to smoothly change the wind direction by the first wind direction plate 34 and the second wind direction plate 35. It is said.

The hard portion 73 and the soft portion 78 of the blade portion 71 may be integrally formed of, for example, a synthetic resin such as polypropylene. At that time, the soft portion 78 may be made thinner than the hard portion 73. In this way, the wind direction of the first wind direction plate 34 and the plurality of second wind direction plates 35 can be finely controlled.

In the present embodiment, the second wind direction plate 35 is basically the same as the first wind direction plate 34, except that the arrangement with respect to the substrate 33 is different from that of the first wind direction plate 34. That is, in the present embodiment, the second wind direction plate 35 has the same shape as the first wind direction plate 34, and the second wind direction plate 35 has the first support shaft 75 of the first wind direction plate 34. It is common in that a second support shaft (support portion) 86 corresponding to the above is provided. On the other hand, the second support shaft 86 differs only in that it is loosely locked to the second opening 70 of the first interlocking plate 44, which will be described in detail below. For this reason, the description of the specific configuration of the second wind direction plate 35 will be omitted.

(Interlocking board)
Subsequently, the first interlocking plate 44 will be described. As shown in FIG. 12, the first interlocking plate 44 has a first opening (locking portion) 69 provided so as to penetrate the plane of the first interlocking plate 44, and a plurality of second interlocking plates 44. The opening (locking portion) 70 of the above is formed.

In the present embodiment, the first opening 69 has a larger opening area than the second opening 70, so that the play when the first interlocking plate 44 swings the first wind direction plate 34 is increased. , The first interlocking plate 44 is formed so as to be larger than the play when swinging the plurality of second wind direction plates 35. In the present embodiment, as shown in FIG. 12, the contour of the first opening 69 is a part of a substantially oval shape in which the longitudinal side is provided obliquely with respect to the longitudinal direction of the first interlocking plate 44. It has a shape that protrudes in a substantially long nose shape toward the side of the first connecting opening 58. On the other hand, the contour of the second opening 70 is a shape in which the circular shape provided on the first interlocking plate 44 extends in a wing shape toward both ends in the longitudinal direction of the first interlocking plate 44. However, the contours of the first opening and the second opening in the present invention are not limited to the shape shown in FIG. 12, and may be, for example, a shape as shown in a modification described later. Further, the effect of the present invention due to such a difference in the amount of play will be described later.

The first opening 69 and the plurality of second openings 70 are respectively configured to lock the first support shaft 75 and the plurality of second support shafts 86 described above with play. ing.

Subsequently, the operation of the wind direction changing device 12 will be specifically described with reference to FIG.

[Operation of wind direction changing device]
13A and 13B are schematic views showing the operation of the wind direction changing device according to the present embodiment, in which FIG. 13A shows the arrangement of the wind direction plate when the drive arm is not swinging, and FIG. 13B shows the arrangement of the wind direction plate when the drive arm is not swinging. The arrangement of the wind direction plate when it swings is shown.

Explaining with reference to these figures, when the first drive arm 52 rotates (swings) in an arc shape along the longitudinal direction of the substrate 33, the first drive arm 52 is connected to the first drive arm 52 accordingly. The interlocking plate 44 also rotates (swings) in an arc shape along the longitudinal direction of the substrate 33. At that time, the first support shaft 75 of the first wind direction plate 34 has a different play size from the second opening 70 in which the second support shaft 86 of the second wind direction plate 35 is locked. It is locked by the first opening 69. Therefore, there is a difference in the positional relationship between the first wind direction plate 34 and the second wind direction plate 35 due to the swing of the first interlocking plate 44.

The results of this difference will be described in more detail with reference to FIG. 13, where the first drive arm 52 (see FIG. 7 and the like) and the second drive arm (not shown) are along the longitudinal direction of the substrate 33. The first wind direction plates 34, 36 and the plurality of second wind direction plates 35, 37 are arranged as shown in FIG. 13A in a state where they are not rotated (swinged) in an arc shape. On the other hand, when the first drive arm 52 and the second drive arm rotate (swing) in an arc shape along the longitudinal direction of the substrate 33, respectively, as shown in FIG. 13B, the substrate 33 The inclination angle of the first wind direction plate 34 with respect to the longitudinal direction of the substrate 33 is smaller than the inclination angle of the second wind direction plate 35 with respect to the longitudinal direction of the substrate 33. This is because the play corresponding to the first wind direction plates 34, 36 interlocked with the arcuate rotation (swing) of the first interlocking plate 44 and the second interlocking plate 45 is the play corresponding to the second wind direction plates 35, 37. This is because the play corresponding to is larger than that of the first wind direction plates 34, 36, as compared with the second wind direction plates 35, 37, respectively, of the first interlocking plate 44 and the second interlocking plate 45. This is because it is less likely to be affected by the arc-shaped rotation (swing).

As a result, the direction of the air blowout flow from the first wind direction plates 34 and 36 is different from that of the second wind direction plates 35 and 37 as shown in FIG. 13B. It is close to the direction of the air blowout flow when no inclination is given to 34 and 36, that is, the direction shown in FIG. 13 (a).

As a result, the flow of air near the side surface of the air outlet of the air conditioner (not shown) is stabilized, so that the generation of the vortex described with reference to FIG. 20 is suppressed. Therefore, it is possible to suppress the alternating occurrence of a state in which the wind normally flows from the outlet and a state in which the wind flows backward, that is, a surging phenomenon. Further, according to this, since the backflow of the wind is suppressed, the backflow of moist wind is cooled by the cold wind, and the occurrence of dew condensation on the side wall surface of the air outlet is suppressed.

In the present embodiment, as described above, the air conditioner is provided with specific parts such as a cleaning device, but the air conditioner of the present invention is provided with at least the wind direction changing device according to the present invention. , It does not have to be equipped with other parts.

Further, the wind direction changing device according to the present embodiment includes a wind direction plate and an interlocking plate having a specific shape, but the wind direction changing devices according to the present invention are spaced apart from each other at least in the longitudinal direction of the substrate. The plurality of wind direction plates are locked with play so that the plurality of wind direction plates supported by the substrate and one end of each of the plurality of wind direction plates swing along the longitudinal direction of the substrate. It has an interlocking plate provided with a plurality of locking portions and a drive unit that swings the interlocking plate along the longitudinal direction of the substrate, and the wind direction supported by the substrate at least on both ends in the longitudinal direction of the substrate. The wind direction plate and the interlocking plate may have other configurations as long as the play size of the plate is different from the play size of the other wind direction plates.

Further, in the present embodiment, the interlocking plate is configured to rotate in an arc shape along the longitudinal direction of the substrate, but for example, the interlocking plate may be configured to reciprocate linearly along the longitudinal direction of the substrate. ..

Further, in the wind direction changing device according to the present embodiment, the plurality of wind direction plates are classified into the right side and left side wind direction plate groups, but these may be integrated.

Further, in the present embodiment, the interlocking plate provided with the opening having a specific shape has been described, but in the present invention, the opening provided in the interlocking plate may have another shape.

Therefore, in the following, a modified example of the shape of the opening in the interlocking plate will be described with reference to FIG. Members having the same functions as the members already described will be designated by the same reference numerals, and the description thereof will be omitted.

[Modification example of opening]
14 (a) to 14 (c) are plan views showing a modified example of the interlocking plate according to the present embodiment, respectively.

First, as shown in FIG. 14A, the interlocking plate 54 has a first opening 69 shown in FIG. 12 in that the inclination angle of the first opening 72 with respect to the longitudinal direction of the interlocking plate 54 is different. The first opening 72, which is different from the above, may be provided. As shown in FIG. 12, the first connecting opening 58 is formed as a long hole long in a direction orthogonal to the longitudinal direction. Then, similarly to the first opening 69, the first opening 72 has an inclination angle with respect to the longitudinal direction, that is, the first opening guided by the first connecting opening 58. This is because the movement direction of the pin 55 (see FIGS. 7 to 9) has an intersecting component with respect to the longitudinal direction.

Alternatively, as shown in FIG. 14 (b), the interlocking plate 64 is different from the first opening 69 shown in FIG. 12 in that the size of the first opening 94 is different. The opening 94 may be provided. The first opening 94 shown in FIG. 14B is provided so that the size of the opening is smaller than that of the first opening 69 shown in FIG.

Alternatively, as shown in FIG. 14 (c), the interlocking plate 84 has a plurality of first openings 77, 96 having different inclination angles with respect to the longitudinal direction of the interlocking plate 84 and different shapes from each other. , The configuration may be different from that of the interlocking plate 44 shown in FIG.

As shown in FIGS. 14A and 14B, the wind direction angle of the first wind direction plate 34 with respect to the longitudinal direction of the substrate can be easily changed by changing the first openings 72 and 94. Can be done.

Further, as shown in FIG. 14 (c), if each of the plurality of first wind direction plates 34 is locked by two or more types of play having different sizes from each other, a plurality of such first wind direction plates 34 are configured. With respect to the first wind direction plate 34, the angle of the wind direction plate with respect to the longitudinal direction of the substrate 33 (see FIG. 7 and the like) can be made different. Therefore, according to this configuration, the blowing direction of the conditioned air can be made different depending on the position in the longitudinal direction of the substrate 33.

Further, in addition to the configuration as shown in FIG. 14, for example, the first opening and the second opening have a circular shape, and the circular shape of the first opening has a circular shape of the second opening. It may be larger than the circular shape of. In such a case, after pointing the first opening into the first support shaft so that the first support shaft does not come out from the first opening, the first support shaft is used. It is preferable to attach a separate pull-out prevention member (not shown).

Explaining with reference to these figures, in the wind direction changing device 15 according to the present embodiment, the interlocking plate 80 is composed of a main interlocking plate 82 and a sub interlocking plate 85. The main interlocking plate 82 has a protruding portion 87 formed by projecting a part thereof upward on the longitudinal end side of the substrate 33, and the protruding portion 87 has an inner wall capable of contacting the sub interlocking plate 85. 88 is formed. On the other hand, the sub-interlocking plate 85 is configured to have a substantially U-shape in front view, and is slidably engaged with the main interlocking plate 82. Further, the sub-interlocking plate 85 has a contact portion 95 that abuts on the inner wall 88 of the protruding portion 87.

The main interlocking plate 82 allows play with a plurality of second wind direction plates 35, which are wind direction plates other than the first wind direction plate (wind direction plate) 34 supported by the substrate 33 on both ends in the longitudinal direction of the substrate 33. A plurality of main openings (main locking portions) 89 are provided for holding and locking. On the other hand, the sub-interlocking plate 85 has a sub-opening 92 (a sub-opening 92) that locks the first wind direction plate (wind direction plate) 34 supported by the substrate 33 at least on the end side in the longitudinal direction of the substrate 33 with play. A sub-locking part) is provided.

Therefore, in the wind direction changing device 15 shown in FIG. 17, the distance that the main interlocking plate 82 moves until the main interlocking plate 82 comes into contact with the second wind direction plate 35, and the sub interlocking plate 85 is the first wind direction plate 34. The distance that the sub-interlocking plate 85 moves to abut on the sub-interlocking plate 85 is set to (L1), and the main interlocking plate 82 (inner wall 88) abuts on the sub-interlocking plate 85 (contact portion 95). Assuming that the moving distance is (L2), the sub-interlocking plate 85 is swung to the distance (L2) by the swing of the main interlocking plate 82, and then the main interlocking plate 82 comes into contact with the sub-interlocking plate 85. For the first time, the sub-interlocking plate 85 can swing the first wind direction plate 34 by a distance (L1).

According to such a configuration, the first wind direction plate 34 starts swinging up to the distance (L1) later than the second wind direction plate 35. At that time, the play of the second wind direction plate 35 corresponds to the distance (L1), while the play of the first wind direction plate 34 corresponds to the distance (L1 + L2). Even with such a configuration, the play of the first wind direction plate 34 can be made larger than the play of the second wind direction plate 35.

In the present embodiment, the same reference numerals are referred to for the members having the same functions as the members described in the first and second embodiments, and the description thereof will be omitted.

Explaining with reference to these figures, in the present embodiment, the wind direction plate 134 is mainly composed of the blade portion 173. The blade portion 173 includes a support opening 174 provided so as to penetrate the plane of the blade portion 173. In the support opening 174, the peripheral wall on the substrate side (not shown) is provided with a first support shaft (support portion) 175 that projects inward from the peripheral wall to the support opening 174. Further, a claw portion 178 is connected to the end of the blade portion 173 arranged on the substrate side. Further, a rotary disk 136 that is rotatable on the upper surface of the substrate is attached to the upper surface of the substrate.

A wind direction plate (first wind direction plate) having motors 47, 48 (driving units) for swinging the plate along the longitudinal direction and supported by a substrate (33) at least on both ends in the longitudinal direction. The size of the play of 34, 36) is different from the size of the play of the other wind direction plates (second wind direction plates 35, 37).

According to the above configuration, the wind direction plate supported by the substrate at least on both ends in the longitudinal direction of the substrate is locked with a play different from the play of other wind direction plates. Therefore, there is a difference in the positional relationship between the wind direction plate and the interlocking plate due to the swing of the interlocking plate. This causes a difference in the wind direction depending on the wind direction plate.

The tilt angle of is smaller than the angle of other wind direction plates. This is because the play in the locking portion of the wind direction plate on both ends is larger than the play in the locking portion of the other wind direction plates, so that the wind direction plate on both ends swings the interlocking plate as compared with the other wind direction plates. This is because it is less likely to be affected by interlocking with. As a result, the direction of the air blow-out flow from the wind direction plates on both ends is closer to the direction of the air blow-out when the wind direction plates on both ends are not tilted, as compared with other wind direction plates.

In the wind direction changing device according to the third aspect of the present invention, in the first aspect, the locking portion is an opening provided so as to penetrate the plane of the interlocking plate, and the wind direction plate is the interlocking plate.

The distance to move one of the plates before starting to move, and the distance corresponding to the wind direction plate supported by the substrate at least on both ends in the longitudinal direction is larger than the distance corresponding to the other wind direction plates. It may be large.

According to the above configuration, in the play, when a driving force is applied to the interlocking plate and the interlocking plate moves, one point of action of the interlocking plate corresponding to one of the wind direction plates is one of the wind direction plates. Corresponds to the distance traveled before contacting. The point of action in contact with one of the wind direction plates changes the direction of one of the wind direction plates along the direction in which the point of action moves by continuing the movement. If the distance is shortened, the point of action abuts quickly on the corresponding wind direction plate, and if the distance is lengthened, the point of action abuts later on the corresponding wind direction plate. Since the movement of each action point matches the movement of the interlocking plate, the total movement distance from when each action point starts moving to when it stops is the same. Then, the point of action that comes into contact with the wind direction plate earlier can change the direction of the wind direction plate more than the point of action that comes into contact with the wind direction plate later. In this way, with a simple configuration, it is possible to realize the generation of a difference in the wind direction due to the wind direction plate.
