FIG. 7 is a plan view showing the relationship among the vane motor 12, the blade link bar 11, and the pedestal link bar 14 of FIG.

The vane motor 12 is provided with a motor rotating plate 15, and a motor slide hole 15 a is formed in the motor rotating plate 15. A motor slide 11a provided at the end of the blade link rod 11 is inserted into the motor slide hole 15a, and the motor slide 11a can freely move along the motor slide hole 15a.

The driving means is composed of a vane motor 12, a motor rotating plate 15 and a blade link rod 11.

Next, the operation of the air conditioner according to Embodiment 1 will be described.

Fig. 8 (a) is a plan view of the left and right wind direction control device 7 when the direction of the left and right blades 9 is the same as the direction of the wind by the fan, and Fig. 8 (b) is a diagram showing that the base slide 14a is deflected by deflecting the left and right blades 9. Fig. 8 (c) is a plan view of the left and right wind direction control device 7 when the pedestal slide 14a is at the curved portion 13b by deflecting the left and right blades 9 It is.

First, when the vane motor 12 is rotated clockwise from the state shown in FIG. 8A, the motor rotating plate 15 rotates and the blade link rod 11 moves to the left in the axial direction.

When the blade link rod 11 is moved to the left in the axial direction, the pedestal slide 14a moves to the left along the guide groove 13 in the pedestal slide hole 8c.

As shown in Fig. 8 (b), while the pedestal slide 14a moves along the straight part 13a of the guide groove 13, Only the direction of the left and right blades 9 is deflected, and the same movement as a conventional air conditioner is performed. On the other hand, when the vane motor 12 is rotated counterclockwise from the state of FIG. 8 (a) and the blade link rod 11 is moved rightward in the axial direction, the pedestal slide 14a moves into the pedestal slide hole 8c and the guide groove. Move along 13 to the right.

As shown in Fig. 8 (c), when the pedestal slide 14a reaches the end of the pedestal slide hole 8c and the curved portion 13b of the guide groove 13, the length of the pedestal link rod 14 is constant. The pedestal rotating bearing 2a is pivoted counterclockwise through the pedestal rotating shaft 8b, and the left and right blades 9 project toward the outside of the outlet 2. Further, since the left and right blades 9 are connected to the blade link rod 11, the left and right blades 9 also rotate counterclockwise about the left and right blade bearings 8a via the left and right blade rotation shafts 9a.

[0014] Next, when the vane motor 12 is rotated clockwise and the blade link rod 11 is moved to the left, the base 8 rotates clockwise around the base rotary bearing 2a via the base rotary shaft 8b. However, the left and right blades 9 that protrude toward the outside of the air outlet 2 move to the inside of the air outlet 2. Further, since the left and right blades 9 are connected to the blade link rod 11, the left and right blades 9 also rotate clockwise around the left and right blade bearings 8a via the left and right blade rotation shafts 9a, as shown in FIG. Return to state.

[0015] Next, the pressure loss of the air conditioner according to Embodiment 1 will be described.

Fig. 9 (a) is an explanatory diagram showing the flow of air when the left and right blades 9A are deflected using a conventional device, and Fig. 9 (b) is the left and right blades 9 using the air conditioner according to Embodiment 1. It is explanatory drawing which shows the flow of the air when deflecting. Here, the interval between adjacent left and right blade rotation shafts 9aA in the air conditioner according to the conventional apparatus and the interval between adjacent left and right blade rotation shafts 9a in the air conditioner according to Embodiment 1 are set to the same distance L.

In the conventional example, the interval between the left and right blades 9A is hi, the interval between the left and right blades 9 in Embodiment 1 is h2, the deflection angles of the left and right blades 9, 9A are the same angle Θ1, and the rotation angle of the base 8 is Assuming Θ 2, hl = LX cos 0 l, h2 = LX cos (0 1 _Θ 2). Naturally, Θ 1 never exceeds 90 degrees, and if we set θ 1> Θ 2, then hl <h2.

Θ 1 and Θ 2 are determined by the length of the straight portion 13 a of the guide groove 13 and the rotation angle of the vane motor 12. Therefore, in the left and right blades 9 of the first embodiment, the contraction of the air flow generated when the direction of the wind is deflected is suppressed as compared with the case of the left and right blades 9A of the conventional example, so that an increase in pressure loss is suppressed. The

Further, since the left and right blades 9 of the first embodiment protrude to the outside of the air outlet 2, collision with the air outlet side wall 2b due to the air flow deflected by the left and right air blades 9 is reduced, and the direction of the wind is high. Sex can be obtained.

FIG. 10 shows a simulation of the relationship between the deflection angle in the wind direction and the pressure loss. The horizontal axis is the deflection angle in the wind direction outside the outlet 2 of the left and right blades 9. The vertical axis represents the pressure loss due to the left and right blades 9. In the first embodiment, the rotation angle Θ 2 of the base 8 is 10 degrees.

As described above, the first embodiment can suppress an increase in pressure loss and obtain a high directionality in the wind direction.

In FIG. 10, the left and right wind direction control device 7 in which the rotation angle Θ 2 of the pedestal 8 is 10 degrees has been described, but of course, the rotation angle Θ 2 is not necessarily 10 degrees. There may be. However, in general, the rotation angle Θ2 is used as 10 degrees or less.

[0018] As described above, according to the air conditioner according to the first embodiment, the pedestal rotary bearing 2a is moved in the middle by rotating the pedestal 8 via the pedestal rotary shaft 8b around the pedestal rotary bearing 2a. Since the left and right blades 9 are inserted into and removed from the outlet 2 at the heart, the pressure loss due to the left and right blades 9 can be reduced.

Further, since one vane motor 12 can drive both the rotation of the left and right blades 9 and the rotation of the pedestal 8, the number of motors can be reduced.

Further, the guide groove 13 is provided with a straight portion 13a and a curved portion 13b, and the rotation of the base 8 can be started or stopped at a predetermined deflection angle of the left and right blades 9. Normally, if the distance between the left and right blades 9 and the fan 5 is too close, noise and pressure loss increase, so this configuration prevents the left and right blades 9 and the fan 5 from being too close. it can

. As a result, noise and pressure loss can be prevented from increasing.

[0020] Further, a guide groove 13 having a straight portion 13a and a curved portion 13b is formed on the outlet bottom surface 2c, and the pedestal slide 14a of the pedestal link rod 14 passes through the pedestal slide hole 8c to form the guide groove 13. Since it is inserted, the pedestal 8 can be rotated with a simple configuration with the left and right blades 9 at a predetermined deflection angle.

[0021] Fig. 11 (a) is a plan view showing another use mode of the guide groove 13 of the first embodiment, and Fig. 11 (b) is a plan view showing another use mode of Fig. 11 (a). Fig. 11 (c) is a plan view showing still another usage mode of Fig. 11 (a).

Unlike the case described above, this mode of use shows an example in which a sufficient distance can be secured between the left and right blades 9 and the fan 5, and there is no increase in noise or pressure loss due to the rotation of the base 8. is there.

By rotating the pedestal 8 in the same rotational direction as the left and right blades 9 rotate, the deflectability of the wind in the left and right direction can be further improved.

As shown in FIG. 11, the straight portion 13c of the guide groove 13 extends from the above-described first embodiment to the inner side of the air passage 3 (in the direction of the fan 5).

Next, the operation of this usage mode will be described.

When the blade link rod 11 is moved to the right as shown in FIG. 11 (b) from the state shown in FIG. 11 (a), the base slide 14a moves into the curved portion 13b of the guide groove 13 in the base slide hole 8c. Move to the right along. At this time, since the length of the pedestal link rod 14 is constant, the pedestal 8 rotates counterclockwise around the pedestal rotation shaft 8b, and the left and right blades 9 protrude toward the outside of the outlet 2. . Further, since the left and right blades 9 are connected to the blade link rod 11, the left and right blades 9 also rotate counterclockwise about the left and right blade rotation shaft 9a.

On the other hand, when the blade link rod 11 is moved leftward from the state shown in FIG. 11 (a) as shown in FIG. 11 (c), the pedestal slide 14a moves in the pedestal slide hole 8c in the straight portion of the guide groove 13. Move left along 13c. At this time, since the length of the pedestal link rod 14 is constant, the pedestal 8 rotates clockwise around the pedestal rotation shaft 8b, and the left and right blades 9 are directed toward the rear side of the air passage 3 (fan 5 side). Rotate.

That is, the left and right blades 9 are deflected in the left-right direction, and the left and right blades 9 are moved not only to the outside of the outlet 2 but also to the inner side of the blower passage 3 through the left and right blade rotation shafts 9a around the base bearing 2a. Can be put in and out.

[0022] According to this air conditioner, the air passage 3 that connects the left and right blades 9 only outside the outlet 2 You can also move in and out. Since the two left and right airflow direction control devices 7 provided at the outlet 2 as shown in FIG. 3 can simultaneously rotate in the same direction on the left and right, the air conditioner according to Embodiment 1 shown in FIG. It is possible to further improve the deflectability of the wind in the left-right direction.

As described above, the shape of the guide groove 13 can be freely formed according to the rotation angle of the left and right blades 9 and the base 8 corresponding to the deflection of the airflow. In other words, the guide groove 13 may be formed by either the straight portion 13c or the curved portion 13b. In addition, as shown in FIG. 8, the straight portion 13a is provided in a direction where the direction of the guide groove 13 and the direction of the pedestal slide hole 8c coincide with each other, thereby rotating the pedestal 8 when the left and right blades 9 are rotated. It is possible not to let it.

In the first embodiment, the guide groove 13 is described as being formed in the outlet bottom surface 2c. However, the present invention is not limited to this, and for example, FIG. 12 (a) and FIG. 12 (b) ), A plate-like base 2d may be provided on the bottom surface 2c of the air outlet, and a guide groove 13 may be formed on the base 2d. The guide groove 13 may be used as long as it guides the pedestal slide 14a. Good.

For example, the guide groove 13 can be easily formed by attaching the base 2d to the outlet bottom surface 2c by means of an adhesive or a pin.

[0024] Further, the pedestal rotating shaft 8b does not need to be provided coaxially with the left and right blade rotating shafts 9a of the left and right blades 9 at the outermost side of the plurality of left and right blades 9 arranged in the lateral direction. Thus, the pedestal rotating shaft 8b only needs to be at a position where the left and right blades 9 can rotate as the pedestal 8 rotates

As in the first embodiment, the vane motor 12 is connected to the blade link rod 11.

[0034] Next, the operation of the air conditioner according to Embodiment 3 will be described.

Fig. 21 (a) is a plan view of the left and right wind direction control device 7 when the direction of the left and right blades 9 is the same as the direction of the wind by the fan 5, and Fig. 21 (b) is a pedestal slide with the left and right blades 9 deflected. FIG. 21 (c) is a plan view of the left / right wind direction control device 7 when the left / right blades 9 are deflected and the pedestal slide 14a is at the curved portion 13b. In the same manner as in the first embodiment, when the vane motor 12 is rotated clockwise from the state shown in FIG. 21 (a), the pedestal slide 14a moves to the left along the guide groove 13 in the pedestal slide hole 8c. Move in the direction. As shown in FIG. 21 (b), while the pedestal slide 14a moves along the straight portion 13a of the guide groove 13, the direction of the left and right blades 9 is merely deflected and the same movement as a conventional air conditioner is performed. . On the other hand, when the vane motor 12 is rotated counterclockwise from the state of FIG. 21 (a), the pedestal slide 14a moves to the right along the pedestal slide hole 8c and along the guide groove 13. As shown in Fig. 21 (c), when the pedestal slide 14a reaches the end of the pedestal slide hole 8c and the curved portion 13b of the guide groove 13, the left and right blades 9 protrude toward the outside of the outlet 2, and the left and right blade bearings The left and right blades 9 rotate counterclockwise around 8a.

At this time, the fixed blade 30 rotates counterclockwise around the base rotation shaft 8b by the rotation of the base 8, and approaches the fan 5 side of the left and right blades 9. The left and right blades 9 and the fixed blades 30 have different deflection angles, and the left and right blades 9 and the fixed blades 30 are shaped like a cocoon-shaped blade.

Next, when the vane motor 12 is rotated clockwise, the left and right blades 9 and the fixed blade 30 that have been protruding toward the outside of the air outlet 2 move to the inside of the air outlet 2. Further, the left and right blades 9 rotate clockwise around the left and right blade bearings 8a and return to the state shown in FIG. 20 (a).

[0036] Next, the pressure loss of the air conditioner according to Embodiment 3 will be described.

FIG. 22 (a) is an explanatory diagram showing the spacing between adjacent left and right blades 9A when the left and right blades 9A are deflected using a conventional device, and FIG. 22 (b) is an air conditioner according to the third embodiment. FIG. 6 is an explanatory diagram showing the interval between adjacent left and right blades 9 when the left and right blades 9 are deflected. Here, the distance L between the adjacent left and right blade rotating shafts 9aA in the air conditioner according to the conventional device and the distance between the adjacent left and right blade rotating shafts 9a in the air conditioner according to the third embodiment are the same distance L.

The interval between the left and right blades 9A in the conventional example is hl, the interval between the left and right blades 9 in Embodiment 3 is h2, the deflection angle of each of the left and right blades 9, 9A is the same angle Θ1, and the rotation angle of the base 8 is Assuming Θ 2, hl = LX cos 0 l, h2 = LX cos (0 1 _Θ 2). Naturally, Θ 1 never exceeds 90 degrees, and if we set θ 1> Θ 2, then hl <h2.

Θ 1 and Θ 2 are determined by the length of the straight portion 13 a of the guide groove 13 and the rotation angle of the vane motor 12. Fig. 23 (a) is an explanatory diagram showing the flow of air when the left and right blades 9A are deflected using the conventional device, and Fig. 23 (b) is a diagram showing the left and right blades 9 using the air conditioner according to Embodiment 3. It is explanatory drawing which shows the flow of the air when deflecting. However, the rotation angle Θ 2 of the base 8 is 10 degrees.

In the conventional device, if the left and right blades 9A are largely deflected, the air flow is largely separated from the left and right blades 9A, resulting in a stagnation region 33A on the surface of the left and right blades 9A. It becomes smaller than the interval h 1 of the blade 9 A.

On the other hand, in the air conditioner according to Embodiment 3, when the left and right blades 9 are largely deflected, θ 1> Θ 2 in the deflection angle Θ 2 of the fixed blade 30 and the deflection angle θ 1 of the left and right blades 9. The size of the stagnation region 33 is smaller than that of the prior art. That is, the air flow path width L2 is less susceptible to contraction due to the stagnation region 33 that is larger than the air flow path width L1 of the conventional apparatus.

[0037] Therefore, in the left and right blades 9 and the fixed blade 30 of the third embodiment, the contraction of the air flow generated when the wind direction is deflected is suppressed as compared with the case of the left and right blades 9A of the conventional example. Increase in pressure loss is suppressed.

In addition, since the left and right blades 9 of the third embodiment protrude to the outside of the blowout port 2, collision with the blowout port side wall 2b due to the air flow deflected by the left and right blades 9 is reduced, and the direction of the wind is high. Sex can be obtained.

In FIG. 23, the left and right wind direction control device 7 in which the rotation angle Θ 2 of the pedestal 8 is 10 degrees has been described, but of course, the rotation angle Θ 2 is not necessarily 10 degrees. There may be. However, in general, the rotation angle Θ2 is used as 10 degrees or less.

Next, the positional relationship between the left and right blades 9 and the fixed blade 30 will be described.

Fig. 24 (a) is a diagram showing the positional relationship between the left and right blades 9 and the fixed blades 30 when the left and right blades 9 and the fixed blades 30 are not deflected. FIG. 5 is a diagram showing the positional relationship between the left and right blades 9 and the fixed blade 30 when 0 is deflected. Here, LH indicates the distance from the left and right blade rotation shaft 9a to the fan 5 side end of the left and right blade 9, and H indicates the distance from the left and right blade rotation shaft 9a to the fixed blade 30.

Positions of fixed blade 30 and left and right blades 9, dimensions of fixed blade 30 and left and right blades 9 As long as the left and right wings 9 and the fixed wing 30 are shaped like a single blade with a U-shape when deflected, they can be in any position and size. In order to obtain the best effect, it is necessary to satisfy the relationship H LH X cos (θ 1− Θ 2).

[0040] As described above, according to the air conditioner according to the third embodiment, the pedestal rotating bearing 2a is moved in the middle by rotating the pedestal 8 about the pedestal rotating bearing 2a via the pedestal rotating shaft 8b. Since the left and right blades 9 and the fixed blade 30 are inserted into and removed from the outlet 2 in the center, pressure loss due to the left and right blades 9 can be reduced.

In addition, since the deflection angle of the fixed blade 30 is smaller than the deflection angle of the left and right blades 9, the stagnation region 33 generated by the fixed blade 30 is reduced, and the width of the air flow path L2 between the left and right blades 9 in contact with P L2 The pressure loss due to the left and right blades 9 can be further reduced.

[0041] Further, the guide groove 13 is provided with a straight portion 13a and a curved portion 13b, and the rotation of the base 8 can be started or stopped at a predetermined deflection angle of the left and right blades 9. Normally, if the distance between the left and right blades 9 and the fixed blade 30 and the fan 5 becomes too close, noise and pressure loss increase. Can be prevented from getting too close. As a result, noise and pressure loss can be prevented from increasing.

[0042] Further, a guide groove 13 having a straight portion 13a and a curved portion 13b is formed on the outlet bottom surface 2c, and the pedestal slide 14a of the pedestal link rod 14 is inserted into the guide groove 13 through the pedestal slide hole 8c. Therefore, with a simple configuration, the base 8 can be rotated with the left and right blades 9 at a predetermined deflection angle.

[0043] FIG. 25 (a) is a plan view showing another usage mode of the guide groove 13 of Embodiment 3, and FIG. 25 (b) is a plan view showing another usage mode of FIG. 25 (a). FIG. 25 and FIG. 25 (c) are plan views showing still another usage mode of FIG. 25 (a).

Unlike the case described above, this mode of use can secure a sufficient distance between the left and right blades 9 and the fixed blades 30 and the fan 5, and there is no increase in noise or pressure loss due to the rotation of the base 8. An example of a match is shown.

As shown in FIG. 25, the straight portion 13c of the guide groove 13 extends from the above-described third embodiment to the inner side of the air passage 3 (in the direction of the fan 5).

Next, the operation of this usage mode will be described.

When the blade link rod 11 is moved to the right as shown in FIG.25 (b) from the state of FIG.25 (a), the pedestal slide 14a moves into the curved portion 13b of the guide groove 13 in the pedestal slide hole 8c. Move to the right along. At this time, since the length of the pedestal link rod 14 is constant, the pedestal 8 rotates counterclockwise around the pedestal rotation shaft 8b, and the left and right blades 9 and the fixed blade 30 face the outside of the air outlet 2. Squeeze out. Further, since the left and right blades 9 are connected to the blade link rod 11, the left and right blades 9 also rotate counterclockwise about the left and right blade rotation shaft 9a.

On the other hand, when the blade link rod 11 is moved leftward from the state shown in FIG. 25 (a) as shown in FIG. 25 (c), the pedestal slide 14a moves in the pedestal slide hole 8c in the straight portion of the guide groove 13. Move left along 13c. At this time, since the length of the pedestal link rod 14 is constant, the pedestal 8 rotates clockwise around the pedestal rotating shaft 8b, and the left and right blades 9 and the fixed blade 30 are connected to the rear side of the air passage 3 (fan 5 To the side).

That is, the left and right blades 9 are deflected in the left-right direction, and the left and right blades 9 and the fixed blades 30 are moved not only to the outside of the outlet 2 but also to the inner side of the blower passage 3 through the left and right blade rotation shafts 9a around the base bearing 2a. Can also be moved in and out.

In this example, the fixed blade 30 is close to the fan 5 side end of the left and right blades 9 regardless of whether the left and right blades 9 are deflected in the left or right direction. The left and right blades 9 and the fixed blade 30 have different deflection angles, and the left and right blades 9 and the fixed blade 30 are shaped like a single blade with a U-shape.

According to this air conditioner, the left and right blades 9 and the fixed blades 30 can be moved into and out of the air passage 3 that connects only the outside of the air outlet 2. As shown in FIG. 18, the two left and right airflow direction control devices 7 provided at the outlet 2 can simultaneously rotate in the same direction on the left and right, so that the air conditioning according to the third embodiment shown in FIG. Wind direction from the machine Can be further improved.

As described above, the shape of the guide groove 13 can be freely formed according to the rotation angle of the left and right blades 9 and the base 8 corresponding to the deflection of the airflow. In other words, the guide groove 13 may be formed by either the straight portion 13c or the curved portion 13b. In addition, as shown in FIG. 20, by providing the straight portion 13a in a direction where the direction of the guide groove 13 and the direction of the base slide hole 8c are aligned, the base 8 is not rotated when the left and right blades 9 are rotated. It becomes possible.

In the third embodiment, the guide groove 13 is described as being formed in the outlet bottom surface 2c. However, the present invention is not limited to this, and for example, FIG. 26 (a) and FIG. 26 (b) ), A plate-like base 2d may be provided on the bottom surface 2c of the air outlet, and a guide groove 13 may be formed on the base 2d. The guide groove 13 may be used as long as it guides the pedestal slide 14a. Good.

Further, the pedestal rotating shaft 8b does not need to be provided coaxially with the left and right blade rotating shafts 9a of the left and right blades 9 located on the outermost side of the plurality of left and right blades 9 arranged in the lateral direction, for example, as shown in FIG. Thus, the pedestal rotating shaft 8b only needs to be in a position where the left and right blades 9 can rotate as the pedestal 8 rotates.

FIG. 28 (a) is a plan view showing another usage example of the air conditioner according to Embodiment 3, and FIG. 28 (b) is a deflection of the air conditioner of FIG. 28 (a). The left and right blade rotation shaft 9a is disposed at the fan 5 side end of the left and right blade 9, and the counter fan 5 side end of the fixed blade 30 is close to the left and right blade rotation shaft 9a. Has been placed.

When not deflected, the fixed blade 30 and the left and right blades 9 are arranged on the same straight line. As a result, the left and right blades 9 and the fixed blades 30 When they are close to each other and deflected, they always have the shape of a single blade with a left and right blade 9 and a fixed blade 30. Can be improved.
