Next, the operation of the air conditioner according to Embodiment 1 will be described.
FIG. 8A 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. FIG. 8C is a plan view of the left / right wind direction control device 7 when the left and right blades 9 are deflected and the pedestal slide 14a is at the curved portion 13b. .
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. 8B, while the pedestal slide 14a moves along the straight portion 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. 8A and the blade link rod 11 is moved rightward in the axial direction, the pedestal slide 14a is inserted into the pedestal slide hole 8c and the guide groove 13. Move to the right along.
As shown in FIG. 8C, when the base slide 14a reaches the end of the base slide hole 8c and the curved portion 13b of the guide groove 13, the length of the base link rod 14 is constant. The left and right blades 9 protrude toward the outside of the outlet 2 by rotating counterclockwise about the rotary bearing 2a via the base rotary shaft 8b. Furthermore, 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.

  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, and the outlet port The left and right blades 9 protruding toward the outside of 2 move to the inside 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 clockwise about the left and right blade bearings 8a via the left and right blade rotation shafts 9a, as shown in FIG. Return to.

Next, the pressure loss of the air conditioner according to Embodiment 1 will be described.
FIG. 9A is an explanatory view showing the flow of air when the left and right blades 9A are deflected using the conventional device, and FIG. 9B is a diagram showing the left and right blades 9 using the air conditioner according to the first embodiment. It is explanatory drawing which shows the flow of the air when deflected. Here, the distance 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.
The interval between the left and right blades 9A in the conventional example is h1, the interval between the left and right blades 9 in the first embodiment is h2, the deflection angle of the left and right blades 9 and 9A is the same angle θ1, and the rotation angle of the base 8 is θ2. Then, h1 = L × cos θ1 and h2 = L × cos (θ1−θ2). As a matter of course, θ1 does not exceed 90 degrees. If θ1> θ2 is set, h1 <h2.
Θ1 and θ2 are determined by the length of the straight portion 13a 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 that occurs 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 blades 9 is reduced, and the direction of the wind is high. Sex can be obtained.

FIG. 10 is a diagram showing 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, and the vertical axis Is a pressure loss due to the left and right blades 9. In the first embodiment, the rotation angle θ2 of the base 8 is set to 10 degrees.
Thus, the thing of Embodiment 1 can suppress the increase in pressure loss, and can obtain the high deflectability in the direction of a wind.

  In addition, although FIG. 10 demonstrates the left-right wind direction control apparatus 7 which made rotation angle (theta) 2 of the base 8 10 degrees, of course, rotation angle (theta) 2 is not necessarily 10 degree | times and may be many times. However, generally, the rotation angle θ2 is used as 10 degrees or less.

As described above, according to the air conditioner according to the first embodiment, the left and right blades are centered on the pedestal rotation bearing 2a by rotating the pedestal 8 via the pedestal rotation shaft 8b about the pedestal rotation bearing 2a. Since 9 is taken in and out from the outlet 2, 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 base 8, the number of motors can be reduced.

  Further, the guide groove 13 is provided with a linear 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, when the distance between the left and right blades 9 and the fan 5 is too short, noise and pressure loss increase, and thus such a configuration can prevent the left and right blades 9 and the fan 5 from being too close. . As a result, noise and pressure loss can be prevented from increasing.

  Further, the guide groove 13 having the straight portion 13a and the 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.

Unlike the above-described case, this usage mode 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. .
By rotating the pedestal 8 in the same rotational direction with the rotation of the left and right blades 9, it is possible to further improve the deflectability of the wind in the horizontal direction.
As shown in FIG. 11, the straight portion 13 c of the guide groove 13 is formed extending from the above-described first embodiment to the back 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 rightward from the state of FIG. 11A, as shown in FIG. 11B, the pedestal slide 14a moves along the curved portion 13b of the guide groove 13 in the pedestal slide hole 8c. To move right. 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 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 rotation shaft 9a.
On the other hand, when the blade link rod 11 is moved to the left as shown in FIG. 11C from the state of FIG. 11A, the pedestal slide 14b moves in the pedestal slide hole 8c and the straight portion 13c of the guide groove 13 Move to the left along. At this time, since the length of the pedestal link rod 14 is constant, the pedestal 8 is rotated clockwise around the pedestal rotation shaft 8b, and the left and right blades 9 are directed toward the back side of the air passage 3 (fan 5 side). Rotate.

Since the two left and right wind 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 flow from the air conditioner according to Embodiment 1 shown in FIG. It is possible to further improve the left-right deflection.
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. That is, the guide groove 13 may be formed by either one of the linear portion 13c or the curved portion 13b. Further, as shown in FIG. 8, by providing the straight portion 13a in a direction in which the direction of the guide groove 13 and the direction of the pedestal slide hole 8c coincide, the pedestal 8 is not rotated when the left and right blades 9 are rotated.
