DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Since the present invention changes the interlocking plate 14 shown in FIG. 6 as the prior art to the interlocking plate 13 shown in FIG. 4, the description of FIG. I will omit it because I can.
[0013]
FIG. 4 is a plan view of the interlocking plate 13. The interlocking plate 13 is a rectangular and long resin plate, and in this plate, a plurality of interlocking holes 21 are located at a position where the dimension L is smaller than the dimension L from one long side and the dimension L is smaller than the other long side. These are arranged on a straight line parallel to these long sides. (Hereinafter, the long side with the dimension L far from the interlocking hole 21 is referred to as the far side long side 23a, and the long side with the dimension M near the interlocking hole 21 is referred to as the near side long side 23b.)
FIG. 3 is a side view of the vertical blade 9. The vertical blade 9 is a flat plate made of resin, and includes a pivot shaft 16 that fits freely in a pivot hole 12 provided in the mounting frame 11 and an interlock shaft 17 that fits in the interlock hole 21 of the interlock plate 13. have.
[0014]
The vertical blades 9 are swung left and right around the rotation shaft 16. The vertical blade 9 is an operation unit that guides the wind direction to the left and right and changes the wind direction. The interlocking shaft 17 is detachably fitted in the interlocking hole 21 of the interlocking plate 13 with the tip of the shaft protruding parallel to the axial direction of the rotating shaft 16 and in the direction opposite to the tip direction of the rotating shaft 16.
[0015]
Further, the vertical blade 9 is formed with a swing limit edge (hereinafter referred to as a contact edge) 18 facing the interlocking shaft 17 and having an interval E parallel to the interlocking shaft 17.
[0016]
In this way, the interlocking holes 21 into which the interlocking shafts 17 of the vertical blades 9 are fitted are arranged on a straight line along the longitudinal direction of the interlocking plate 13, and the dimensions L and M are set so as to be asymmetric between the front side and the back side. ing. Further, the interlocking plate 13 is fitted with an interlocking shaft 17 from either the front side or the back side, and by moving the interlocking plate 13, the entire vertical blade 9 can be interlocked to swing left and right.
[0017]
A notch 22 is formed in the center of the long side 23a on the far side, and serves as a mark for distinguishing the long side 23a from the long side and the long side 23b on the near side. Further, a projection piece 24 is provided at the end of the far side long side 23a, and the distance between the projection piece 24 and the short side is formed to be approximately the same as the distance between the interlocking hole 21 near the projection piece 24 and the short side. Has been.
[0018]
FIG. 1 is a plan view of a wind direction adjusting device of the present invention. The pivot hole 12 of the mounting frame 11 is pivotally mounted with the pivot shaft 16 of the vertical blade 9 substantially downward and the interlocking shaft 17 of the vertical blade 9 rearward (windward). The interlocking plate 13 is pivotally attached to the interlocking shaft 17 of the vertical blade 9 with the long side 23b on the near side being the vertical blade 9 side (front side).
[0019]
Since the distance E between the interlocking shaft 17 and the contact edge 18 is larger than the M dimension of the interlocking plate 13 when the vertical blade 9 is in the front position, the distance between the near side 23b of the interlocking plate 13 and the contact edge 18 is longer. A sufficient space is secured between the vertical blades 9 for large swinging between the left and right sides.
[0020]
As shown in FIG. 2, when the vertical blade 9 is swung to the right (the lower side in the drawing), the interlocking plate 13 moves to the left, and the near-side long side 23 b and the contact edge 18. And the vertical blade 9 comes into contact with the contact edge 18 at a predetermined angle (for example, an angle of about 45 degrees in FIG. 2). Similarly, when the front edge of the vertical blade 9 is swung to the left, the vertical blade 9 is in contact with the contact edge 18 at a predetermined angle, and the wind direction is adjusted in this left and right swing angle range.
[0021]
In this embodiment, it is set to a range of 45 degrees on the left and right. The maximum swing angle of the vertical blade 9 is changed by changing the dimension between the interlocking hole 21 and the long side 23 of the interlocking plate 13 with respect to the dimension E between the interlocking shaft 17 and the contact edge 18. It is.
[0022]
The interlocking plate 13 is pivotally attached to the interlocking shaft 17 by inverting the front and back sides so that the near long side 23a is on the vertical blade 9 side and the far side long side 23a is on the vertical blade 9 side. Can do.
[0023]
As shown in FIG. 5, when the far side 23a is pivoted to the interlocking shaft 17 with the long side 23a facing the vertical blade 13, the long side 23a is longer than the near side 23a pivoting to the vertical blade 9 side. Since the gap between the contact edge 18 and the contact edge 18 is narrowed, the contact edge 18 and the long side 23 contact each other while the swinging angle of the vertical blade 9 is small. In FIG. 5, the wind direction is adjusted in the swing angle range of 20 degrees on the left and right.
[0024]
Thus, in the interlocking plate 13 of the present invention, the plurality of interlocking holes 21 are arranged so as to be offset from the centers of the long sides 23a and 23b along the longitudinal direction of the interlocking plate 13, and which of the long sides 23 is vertical. Since it can be pivotally attached to the interlocking shaft 17 of the vertical blade 9 even toward the blade side, when assembling the wind direction adjusting device 8, the front and back of the interlocking plate 13 are reversed so that one interlocking plate 14 can be used in two ways. The wind direction adjusting device 8 having the maximum swing angle can be provided.
[0025]
Since the interlocking plate 13 can pivotally mount the interlocking shaft 17 of the vertical blade 9 from either the front side or the back side, there is a possibility that the interlocking plate 13 may be mistakenly assembled during the assembly operation when the wind direction adjusting device 8 is assembled. Therefore, a cutout 22 and a protruding piece 24 are formed on one long side of the interlocking plate 14.
[0026]
FIG. 7 is a plan view of the wind direction adjusting device when the protruding piece side of the interlocking plate is pivotally attached to the vertical blade side, and FIG. 8 is a partially enlarged view of FIG.
[0027]
In this embodiment, the notch 22 is a mark for distinguishing the long side 23a from the far side and the long side 23a from the near side, and the protruding piece 24 extremely restricts the swinging of the vertical blades 9 together with the same distinction. It is provided as something to do. If the protruding piece 24 is provided on the long side when the swinging of the vertical blade 9 is restricted, the protruding piece 24 will contact the edge 18 of the vertical blade 9 even if the vertical blade 9 swings slightly to the left. Since the vertical blade 9 is slightly swung to the left and right, it can be easily confirmed whether or not the rocking restriction assembly has been assembled or the interlocking plate 13 has been attached by mistake.
[0028]
In addition, when assembling the wind direction adjusting device 8 with the protruding piece 24 facing the vertical blade 9 side, the protruding piece 24 may not be able to ensure practical oscillation unless the protruding piece 24 is excised with a nipper or the like. Since the protruding piece 24 is formed at an end that can be easily cut, there is no difficulty in the excision work. In addition, when the protruding piece 24 side cannot be used unless it is cut, the protruding piece 24 is provided on the long side on the less frequently used side.
[0029]
As mentioned above, although this invention was demonstrated based on one Embodiment, this invention is not limited to this.
[0030]
【The invention's effect】
As described above, according to the present invention, in the wind direction adjusting device configured to limit the swing angle range of the vertical blade by bringing the interlocking plate of the wind direction adjusting device into contact with the edge of the vertical blade, the vertical blade of the interlocking plate Set the swing angle of the two vertical blades according to the dimensions of the long side of the interlocking plate and the interlocking shaft, and reduce the normal range of swing angle range of the vertical blade and narrow the swing angle range. The design of special use was made easy, so the right and left swing angles of the blown air can be adjusted even when dew adheres to the vicinity of the air outlet due to special conditions of indoor temperature and humidity. It is possible to provide an air conditioner that is restricted to prevent such dew condensation.
[0031]
Also, when using the long side on the special use side, it is necessary to cut the protruding pieces so that they can not be used properly, and it is easy to check even when assembled incorrectly or when checking after assembling the wind direction adjusting device. It is possible to provide an air conditioner that can prevent dew condensation more reliably.
