Description

  The present invention relates to a wind direction adjusting device and an indoor unit of an air conditioner, and more particularly to a wind direction adjusting device installed in an indoor unit of an air conditioner, and an indoor unit of an air conditioner in which the wind direction adjusting device is installed.

At the air outlet of the indoor unit (same as the indoor unit) of the air conditioner, a wind direction adjusting device that adjusts the blowing direction of the cooled or heated air is installed. In the past, such a wind direction adjusting device has been disclosed that includes a wind direction plate (same as a vertical flap) having a soft part that can be bent, and adjusts the blowing direction by curving the soft part (for example, Patent Documents). 1).
Further, a driving arm and a driven arm arranged in parallel to each other, a plurality of first-direction wind direction plates (vanes) whose both ends are rotatably connected to the driving arm and the driven arm, and the driving arm and the driven arm A plurality of wind direction plates (vanes) in a second row whose both ends are pivotally connected to each other, and formed by a drive arm, a driven arm, and a plurality of wind direction plates in the first row. By changing the inclination angle of the shape (the angle formed by the base and the hypotenuse) and the inclination angle of the parallelogram formed by the driving arm, the driven arm and the second row of wind direction plates, the blowing direction is changed. What is adjusted is disclosed (for example, refer to Patent Document 2).

Japanese Utility Model Publication No. 3-37351 (page 6-8, FIG. 3) JP 2007-132636 A (page 5, FIG. 6)

In the wind direction plate disclosed in Patent Document 1, since the soft portion sandwiched between the rigid portions disposed at both ends is bendable and extendable, the material for forming the wind direction plate is limited and rigid. There was a possibility that the joint surface between the part and the soft part might peel off. For this reason, there existed a problem that reliability increased while manufacturing cost raised.
On the other hand, the first row of wind direction plates and the first row of wind direction plates disclosed in Patent Document 2 are integrally formed, so the problem is solved. However, the first row of wind direction plates and the second row of wind direction plates are arranged in a staggered manner, that is, at a predetermined interval on a plane perpendicular to the blowing direction. For this reason, the problem is that the air flow collides with both the windward end surface of the first row wind direction plate and the windward end surface of the second row wind direction plate, resulting in increased ventilation resistance and energy loss. was there.

  The present invention has been made in order to solve the above-described problems, and is provided with a wind direction adjusting device capable of suppressing an increase in ventilation resistance and obtaining an energy saving effect, and an air conditioner provided with the wind direction adjusting device. The indoor unit is obtained.

A wind direction adjusting device according to the present invention includes a base,
A first vane rotatably mounted on the base at a reference rotation center;
A second vane rotatably mounted on the first vane at the connecting rotation center;
A movable member rotatably installed at the first vane at the first rotation center and the second vane at the second rotation center;
Drive means for moving the moving member relative to the base;
Have
A first imaginary line connecting the reference rotation center and the connection rotation center and a second imaginary line connecting the connection rotation center and the second rotation center according to an amount of relative movement of the moving member. The formed angle varies.

In the wind direction adjusting apparatus according to the present invention, the first vane is rotated with the reference rotation center as a fulcrum and the first rotation center as a power point by the movement of the moving member, and the connection rotation center moves along an arcuate locus. Similarly, the second vane is rotated by the movement of the moving member about the connection rotation center as a fulcrum and the second rotation center as a power point.
At this time, since both the first vane and the second vane are rotatably connected at the connection rotation center, the first vane and the second vane behave as if they are a single plate. In particular, when blowing out in the front direction, the first vane and the second vane overlap to form a single flat plate, so that the air only collides with one end face of the first vane or the second vane, As in the case of the staggered arrangement, the end faces of both the first vane and the second vane do not collide. Therefore, the air flow becomes smooth, an increase in ventilation resistance is suppressed, and an energy saving effect is obtained.
In the above description, the second vane is rotated with the connection rotation center as a fulcrum and the second rotation center as a power point. However, the second vane is rotated with the connection rotation center as a force point and the second rotation center as a fulcrum. May be considered.

The abutting range is formed on a plane perpendicular to the axis of the first moving bearing 31. Therefore, in the assembled state, the upper end surface of the first moving seat 16c of the first member 10 abuts on the lower surface of the moving main body 33 (Note that in FIG. 4, it is necessary to facilitate understanding of the assembled state of each part. It is drawn with a gap between the abutting members).
Further, a slit-like moving groove 31 a is formed on both sides of the first moving bearing 31 in the longitudinal direction, so that the first moving shaft 16 can be easily installed (inserted) into the first moving bearing 31. .

On the other hand, the second moving bearing 32 supports the second moving shaft 26 of the second member 20 so as to be rotatable and movable in the Y direction in the assembled state, and is a long hole extending in the Y direction.

(Driving means)
Further, one end of the connecting rod 51 is rotatably connected to one end of the moving main body 33, and a motor connecting member 52 is rotatably connected to the other end of the connecting rod 51. ing.
The motor connecting member 52 includes a motor connecting portion 52 a connected to the output shaft of the motor 53, and a motor connecting arm 52 b fixed to the motor connecting portion 52 a and having a tip connected to the connecting rod 51.
Therefore, when the motor 53 rotates, the motor connecting rod moves in translation. The motor connecting member 52 is not limited to the above configuration, and may have a rack / pinion structure. In place of the motor 53, an actuator such as a solenoid may be installed.

  In the assembled state shown in FIG. 4, the first moving shaft 16 penetrates the first moving bearing 31 and protrudes from the upper surface of the moving main body portion 33, so the first moving shaft 16 and the protruding portion 24 of the second member. In order to avoid interference, the upper surface of the movable arm portion 34 protrudes from the upper surface of the movable body portion 33 by an amount slightly larger than the protruding amount. At this time, the moving body 33 and the moving arm 34 have the same thickness (a step is formed between the lower surface of the moving body 33 and the lower surface of the moving arm 34), or the moving body 33 is moved to the first position. The entire length of the moving shaft 16 may be made retractable (the step between the upper surface of the moving main body 33 and the upper surface of the moving arm portion 34 is eliminated, and the weight increases).

(Base)
In the assembled state, the base 40 includes a support surface 41 that supports the end surface of the reference shaft 11 perpendicularly to the reference rotation center A, the reference shaft 11 so as not to be detached from the base 40, and the reference shaft 11. Holding means (claw surrounding the disc-shaped reference shaft flange 11a formed so as to protrude from the side surface of the reference shaft 11) 42 that holds the reference rotation center A rotatably.
Moreover, the rotation latching | locking part 43 which latches freely to the drain pan lower surface 142 at one end part of the base 40, and the base 40 installed in the drain pan lower surface 142 does not rotate at the other end part. A fixing locking portion 44 is provided for fixing in this manner.
That is, as will be described later, during the operation of the indoor unit 100, the base 40 is installed in the vertical direction (X direction) with respect to the air path 113, and when cleaning the indoor unit 100, It is possible to project a part from the air outlet 112 to the outside of the main body 110.

(Material)
As described above, the base 40 is made of PP resin, the first member 10 is made of ABS resin, the second member 20 is made of POM resin, and the moving member 30 is made of PP resin. The present invention does not limit the materials forming these members to the combinations described above, and other combinations may be used. In addition, the same material may be connected (contacted), and a lubricating means may be installed (applied with a lubricant) on the rolling portion (contacting portion).

(Operation-Front blow)
6A and 6B, the airflow direction adjusting device 200 includes a reference shaft 11 (reference rotation center A), a first moving shaft 16 (first rotation center C), and a connection shaft 15 ( The connecting rotation center B) is located on a straight line in the Y direction. Further, the second moving shaft 26 (second rotation center D) and the connection bearing 25 (connection rotation center B) of the first member 20 are positioned on a straight line in the Y direction.
Therefore, the 1st wind direction board 12 and the 2nd wind direction board 22 are located in a line with the Y direction. At this time, since one side edge 13 of the first wind direction plate 12 and the other side edge 23 of the second wind direction plate 22 are close to each other, both of them are shaped like a single flat plate.
Therefore, air only collides with the windward end face of the second wind direction plate 22, and the first wind direction plate 12 as in the conventional staggered arrangement (arranged in parallel with a predetermined interval). And it does not collide with both end faces of the second wind direction plate 22. Therefore, the air flow becomes smooth, an increase in ventilation resistance is suppressed, and an energy saving effect is obtained.

That is, if the second wind direction plate 22 is arranged on the upstream side of the air passage 113 and the first wind direction plate 12 is arranged on the downstream side of the air passage 113, the air flow collides with both side edges or from both side edges. Since it does not peel off, an increase in ventilation resistance is suppressed and an energy saving effect is obtained.
At this time, in both the first wind direction plate 12 and the second wind direction plate 22, one surface (for example, the surface on the + X direction side) is a positive pressure surface (the flow velocity is fast), and the other surface (for example, the −X direction side). ) Is not clear on the negative pressure surface (the flow velocity is slow), and vibrations may occur in one or both of the first wind direction plate 12 and the second wind direction plate 22 due to flow variations. However, in the wind direction adjusting device 200, when the front blowing is performed, the contact protrusion 27 of the second member 20 is in contact with the upper end edge 14b of the notch portion 14 of the first member 10, so that such vibration is suppressed. .

(Operation-oblique blow)
7 (a) and 7 (b), the first member 10 of the wind direction adjusting device 200 has the first moving shaft 16 because the moving member 30 (first moving bearing 31) is moved in the -X direction. The (first rotation center C) and the connection shaft 15 (connection rotation center B) each draw an arc-shaped locus with respect to the reference axis 11 (reference rotation center A), which is a fixed point, and mainly in the −X direction. Has moved. The first imaginary line L1 connecting the reference axis 11 (reference rotation center A), the first movement axis 16 (first rotation center C), and the connection shaft 15 (connection rotation center B) is “angle” with respect to the Y direction. (Hereinafter referred to as “first inclination angle”) φ ”is inclined.
On the other hand, in the second member 20, the connecting bearing 25 moves in the same manner as the connecting shaft 15. The second moving shaft 26 (second rotation center D) moves in the −X direction by the same distance as the first moving shaft 16 and moves in the −Y direction within the second moving bearing 32. Therefore, the second imaginary line L2 connecting the coupling bearing 25 (second coupling rotation center B) and the second moving shaft 26 (second rotation center D) is “angle” (hereinafter referred to as “second inclination”) with respect to the Y direction. The angle is referred to as “θ”.

And since one side edge 13 of the 1st wind direction board 12 and the other side edge 23 of the 2nd wind direction board 22 are adjoining, both are as if one flat plate in the connection shaft 15 (connection bearing 25). It has a bent shape.
That is, similarly to the front blowing, if the second wind direction plate 22 is arranged on the upstream side of the air passage 113 and the first wind direction plate 12 is arranged on the downstream side of the air passage 113, the air flow collides with both side edges, Since it does not peel from both side edges, the increase in ventilation resistance is suppressed, and an energy saving effect is obtained.
At this time, the contact protrusion 27 of the second member 20 is separated from the upper end edge 14b of the notch portion 14 of the first member 10, but both the first wind direction plate 12 and the second wind direction plate 22 are on one side. (For example, the surface on the + X direction side) becomes clear on the positive pressure surface (the flow velocity is fast), and the other surface (for example, the surface on the -X direction side) becomes clear on the negative pressure surface (the flow velocity is slow). Even if the variation occurs, vibrations do not occur in one or both of the first wind direction plate 12 and the second wind direction plate 22 (less).

In FIG. 7B, the distance between the centers of the first moving shaft 16 and the connecting shaft 15 of the first member 10 is “m”, and the distance between the centers of the second moving shaft 26 of the second member 20 and the connecting bearing 25 is set. When the distance is “n”, both of them are: m · sin (φ) = n · sin (θ) (1)
There is a relationship.
Therefore, for example, the first inclination angle φ with respect to the air path 113 of the first wind direction plate 12 arranged on the downstream side is set to “the second inclination angle θ with respect to the air path 113 of the second wind direction plate 12 arranged on the upstream side”. To double it,
m · sin (2 · θ) = n · sin (θ) ··· Equation (2)
n / m = 2 · cos (θ) (3)
If there is a relationship.

Therefore, when the angle θ is changed from “−30 ° to + 30 ° (−3 <θ <+30)”, for example, “cos (20 °) = 0.940” is substituted,
n / m = 1.88 Expression (4)
It becomes.
Further, the length “p” of the second moving bearing 26 in the Y direction is:
p = n · (cos (0 °) −cos (30 °)) (5)
p = n · (1−0.866) = 0.13 · n Equation (6)
(Note that if n / m is fixed, the value of φ / θ slightly fluctuates, so that the expression (6) is not strictly accurate).

In the wind direction adjusting device 200 described above, for example, the center of the connecting shaft 15 and the connecting bearing 25 and the center coincide with each other at the connecting rotation center B, or the upper end surface and the lower end surface perpendicular to the connecting rotation center B are provided. However, the term “coincidence” or “vertical” does not refer to geometrically strict “coincidence” or “vertical”. This includes an allowable error.
Further, the installation positions of the shaft and the bearing that supports the shaft may be switched. For example, instead of providing the connecting shaft 15 on the first member and the connecting bearing 25 on the second member, a connecting bearing that provides the connecting shaft on the second member and supports the connecting shaft on the second member is provided. It may be provided.
Further, the first moving shaft 16 may be installed on the upper end edge 14 b of the notch portion 14, and the moving member 30 may be disposed above the protruding portion 24 of the second member 20. At this time, the second moving shaft 26 is provided on the upper surface of the protruding portion 24.

  In FIG. 1B, the indoor unit 100 is stopped, and the wind direction adjusting device 200 protrudes outward from the air outlet 112. That is, the fixed locking portion 44 of the base 40 is separated from the drain pan lower surface 142 and rotates around the rotation locking portion 43. Therefore, the pair of wind direction adjusting devices 200 arranged on the left and right are opened in a double-spread shape. Therefore, it becomes easy to clean the inside of the main body 110 and the wind direction adjusting device 200 itself.

  According to the present invention, since it is possible to set (change) the blowing direction of air while suppressing an increase in ventilation resistance, since it is excellent in energy saving, as various wind direction adjusting devices installed at the air outlet, Further, it can be widely used as an indoor unit of various air conditioners in which the wind direction adjusting device is installed.
