[0026]
Next, the configuration of the left and right wind direction plate assembly 20 will be described in detail with reference to FIGS. 3 (A) to 3 (D).
[0027]
The left and right wind direction plate assembly 20 is configured such that the plurality of left and right wind direction plates 3 are swingably erected via a first hinge portion 11 including a first thin portion 11 ′, and are arranged at a lower edge of the air outlet 2. A plurality of first plates provided at the air outlet 2. The horizontal plate 12 is formed along the horizontal plate 12 at both ends of the horizontal plate 12 and is formed along the side walls of the air outlet 2. An assembly frame 16 that is integrally formed with a first locking claw 15 that is detachably locked to the locking portion 14, and is integrally formed at the upper ends of the left and right wind direction plates 3, and these are formed into a second thin wall It comprises a plurality of connecting plates 19 that are swingably connected as a plurality of left and right wind direction plate groups via a second hinge portion 17 consisting of a portion 17 ', and these are integrally formed of an elastic synthetic resin such as polypropylene, for example It has been configured.
[0028]
The first hinge portion 11 has a configuration in which the first hinge portion 11 is continuously formed on an upper portion thereof through a base portion 12 'that projects from the front and back of the horizontal plate 12, thereby easily integrating the portion. It can be molded.
[0029]
In addition, the first hinge portion 11 is formed by dividing the front portion 12 ′ and the left and right wind direction plates 3 in the front-rear direction so that the strength of the portion can be maintained and the hinge effect can be maintained. As a result, the left and right wind direction plates 3 can be swung more smoothly.
[0030]
By the way, since the upper and lower wall surfaces constituting the outlet 2 are generally formed so that the front end side is expanded, the connecting plate 19 is provided with a recess provided on the upper wall surface of the outlet 2. Since the second hinge portion 17 is in a state of being twisted when held in a slidable manner to the left and right by the shaped holding portion 18, the second hinge portion 17 is preferably formed to be slightly longer than the first hinge portion 11.
[0031]
The connecting plate 19 is integrally formed with a lever 19b for hooking fingers, and the lever 19b allows the connecting plate 19 to be easily slid left and right so that the vertical wind direction plate 3 is interlocked and swung. Can be done.
[0032]
When the connecting plate 19 is slid, as shown in FIGS. 3 (A) to 3 (C), the holding portion 18 has an uneven line 19a formed on the back surface of the connecting plate 19. And a projection 18b for positioning the connecting plate 19 at a predetermined left and right position.
[0033]
As shown in FIG. 3A, the horizontal plate 12 of the assembly frame 16 includes a support shaft portion 27 that rotatably supports an intermediate support shaft provided on the up-and-down wind direction plate 3. The upper and lower walls are joined between the upper and lower walls of the outlet 2 and are formed so as to be joined to a vertical beam 26 having a joint recess at the front, and provided on the upper wall of the outlet 2 at the upper end. Further, a support plate 28 provided with a second locking claw 30 that is detachably locked to the second locking portion 29 is erected.
[0034]
A plurality of the support plates 28 are erected on the horizontal plate 12 of the assembly frame 16, and the second locking claws 30 at the upper end portions of the support plates 28 are locked to the second locking portions 29. Thus, the vertical wind direction plate 4 can be accurately supported so as not to bend.
[0035]
Further, by disposing the connecting plates 19 on both sides of the support plate 28, the left and right wind direction plates 3 can be disposed at equal intervals as appropriate, and the wind direction in the left and right direction can be effectively changed.
[0036]
Next, based on FIG. 4 (A) and FIG. 4 (B), the linkage shaft 4a integrally formed on one side of the up-and-down wind direction plate 4 and the rotary shaft integrally formed on the other side are pivotally supported. The configuration will be described.
[0037]
The linkage shaft 4a is rotatably supported by a vertical plate 13 of the assembly frame 16 and / or a first support shaft hole 2b provided in a side wall 2a of the blowout port 2, and the second drive motor 9 includes a driven gear 23 that meshes with a drive gear 22 provided on the drive shaft 9, and a rotary shaft that is integrally formed on the other side includes a vertical plate 13 of the assembly frame 16 and / or the blower gear. The second support shaft hole 2c provided in the side wall 2a of the outlet 2 is rotatably supported.
[0038]
Then, a substantially U-shaped notch hole 2b ′ as shown in FIGS. 4A and 4B is continuously formed in the first support shaft hole 2b, while the notch hole 2b is formed in the driven gear 23. Since the projecting portion 24 that can be inserted and removed from the upper and lower wind direction plates 4 is provided, the driven gear 23 that is integrally formed with the linkage shaft 4a of the up-and-down wind direction plate 4 can be easily attached to the drive gear 22. And it becomes possible to mesh accurately.
[0039]
Although not shown, the connecting plate 19 may be formed so as to connect the upper ends of all of the plurality of up-and-down air direction plates 3 as a group of up-and-down air direction plate assemblies without being divided into a plurality of pieces.
[0040]
Next, the holding portion 18 provided on the upper wall surface of the air outlet 2 corresponding to the connecting plate 19 and holding the connecting plate 19 so as to be slidable left and right will be described.
[0041]
The holding portion 18 is longer than the left and right lengths of the connecting plate 19 and slightly larger than the vertical width so that the connecting plate 19 can slide smoothly to the left and right. As shown in FIG. 3 (D), a plurality of guides 18a are formed to hold the connecting plate 19 so that it can be inserted and removed and slidable left and right as shown in FIG. ing.
[0042]
When the connecting plate 19 is inserted into the holding portion 18, the connecting plate 19 is twisted and elastically deformed so that the second hinge portion 17 is attached to the second hinge portion 17 as described above. The fact that it is formed a little longer than one hinge part 11 is useful.
[0043]
Further, as shown in FIG. 3A, a plurality of support plates 28 provided with a support shaft portion 27 for pivotally supporting the up-and-down wind direction plate 4 on the horizontal plate 12 of the assembly frame 16 are erected. Since the second locking claw 30 detachably locked to the second locking portion 29 provided on the upper wall of the air outlet 2 is provided at the upper end thereof, the strength of the assembly frame 16 is increased. In addition, the vertical wind direction plate 4 can be supported more accurately.
[0044]
Further, as shown in FIG. 3 (A), since a shield 25 facing the electrical component 10 is integrally formed on the side of the assembly frame 16, the location facing the electrical component 10 is A cost-effective configuration enables accurate shielding.
[0045]
In addition, the air outlet 2 is provided with an accommodation recess 21 for accommodating the assembly frame 16 in a flush manner, and a part of the air outlet 2 is formed by the assembly frame 16 accommodated in the accommodation recess 21. It is configured.
[0046]
As described above, the left and right wind direction plates 3 are integrally formed at a low cost as the left and right wind direction plate group assembly 20 and unitized, so that the workability for assembling to the air outlet 2 can be improved. Further, as shown in FIG. 1, the mounting plate A serves as a part of the base a, and a sealing member E is interposed at the joint between the base a and the mounting plate A. As a result, the mold for producing the base a can be greatly simplified, and the cost reduction of large parts can be promoted to provide an inexpensive product with a reduced mass.
[0047]
