However, the above-described conventional wind direction device requires three parts, namely, a wind direction plate, an interlocking plate, and a mounting plate, and furthermore, the wind direction plate and the interlocking plate have a dowel for coupling with each other. It takes time and effort to fit by fitting the fitting hole and fitting, and also to assemble by fitting the U-shaped elastic holding arm piece of the fitting plate to the rotating shaft of the wind direction plate that has come out slightly below. In addition, there is a problem that the cost is high.

The present invention has been made in view of the above points, and has as its object to provide an air conditioner equipped with a wind direction device which can reduce the number of parts and improve assemblability and can be assembled at low cost. I do.

[0012]

According to the present invention, in order to achieve the above object, a heat exchanger and a blower are arranged in an air passage in a main body connecting an air suction port and an air discharge port, and the suction is performed by the blower. After cooling / heating the air taken in from the mouth with the heat exchanger, the air is blown out from the air discharge port,

Is what it is.

[0014]

Embodiments of the present invention will be described below with reference to the drawings.

First, conventionally, a plurality of wind direction plates 10 made of a resin member are connected and attached by a resin interlocking plate 12 which is a separate member. In the present invention, however, this separate member interlocking plate 12 is connected. Instead of using it, the wind direction plate 10 can be integrally connected and mounted.

As shown in FIG. 1, a plurality of resin wind direction plates 3 are attached to a resin interlocking plate 30 by integral molding.
1 are connected to each other by a thin hinge portion 32 so as to be integrally formed. AB as the resin material
S and P. S or P. By using P or the like, the thickness of the hinge portion 32 is such that the direction of the wind direction plate 31 is easily changed and is not cut.

With such a thin hinge portion 32, if the wind direction body 35 has a configuration in which a plurality of wind direction plates 31 are integrally connected to the interlocking plate 30, when an arbitrary wind direction plate 31 is moved to the left and right, the interlocking operation is performed. The remaining wind direction plates 31 also move in the same direction with the moved wind direction plates 31 via the plates 30.

Each wind direction plate 31 is a conventional wind direction plate 10.
Similarly to the above, there is a retaining flange 36 at the lower part, and the rotating shaft 37 is formed so as to extend below it.

Next, these wind direction plates 31 are mounted in the blowout frame 13. That is, the lower surface plate 13b of the blowout frame 13 is provided with a circular mounting hole 38 for inserting and supporting the rotation shaft 37 of each wind direction plate 31. Through which the wind direction plate 31 is attached and supported.

Conventionally, after this, the mounting plate 14
U-shaped elastic holding arms 23, 2 of the mounting plate 14
3 is fitted to the rotating shaft 18 that has come out downward, and the wind direction plate 31 is rotatably mounted and fixed by utilizing the frictional force between the elastic holding arm pieces 23 and 23 and the rotating shaft 18. I was

However, in the present invention, the wind direction plate 31 is designed to be rotatably fixed without using the mounting plate 14.

That is, of the plural wind direction plates 31,
As shown in FIG. 2 and the like, at least one of the wind direction plates 31P is provided with one fixing projection 40 formed on the peripheral surface of the rotation shaft 37 so as to be elastically deformable and having a thickness h. I have. And the wind direction plate 3 provided with the fixing protrusion 40.
1P is provided with a handle 41 for rotating the wind direction plate to the left and right.

On the other hand, on the lower surface plate 13b of the blowout frame 13,
As described above, the same number of circular mounting holes 38 as the wind direction plates 31 for inserting the rotation shafts 37 of the respective wind direction plates 31 are formed. On the inner peripheral surface of the mounting hole 38P into which the wind direction plate 31P having the projecting piece 40 is inserted, a plurality of stop grooves 42 having a width l (see FIG. 5) slightly larger than the thickness h of the fixing projecting piece 40 are provided. In the embodiment, the electrodes are formed at equal intervals of 90 °.

Here, the shaft diameter f (see FIG. 2) of the rotating shaft portion 37 including the fixing projection 40 of the wind direction plate 31P is determined by the inner diameter j of the mounting hole 38P in which the wind direction plate 31P is mounted. Designed to have slightly larger dimensions.

Accordingly, among the plurality of wind direction plates 31 rotatably supported by inserting the rotation shaft 37 into the mounting holes 38 of the lower surface plate 13b of the blowout frame 13, the wind direction plate 31P provided with the handle 41 is provided. When the handle 41 is rotated in one of the right and left directions, all the wind direction plates 31 rotate in the same direction via the interlocking plate 30 with the movement of the wind direction plate 31P.

At this time, in the wind direction plate 31P, the fixing projection 40 on the rotation shaft 37 of the wind direction plate 31P is slightly bent, and rotates while elastically contacting the inner surface of the mounting hole 38P. The protruding piece 40 comes off the inner surface of the mounting hole 38P and enters the stop groove 42. Then, since the piece of the fixing projection 40 is engaged with the stop groove 42, the wind direction plate 31P is held at the rotated position so as not to move in the stop groove 42 unless an external force is applied. Of course, all the remaining wind direction plates 3 in the wind direction body 35 other than the wind direction plate 31P.
1 also faces the same direction and stops.

In this way, since one wind direction plate stops, the other wind direction plates also stop in the same direction as the stopped wind direction plate. By providing such a stopping means on a specific one wind direction plate, the mounting plate 1 of the wind direction plate as in the related art can be provided.
Even without using 4, the wind direction plate can be held at the rotated position in that direction.

Here, in the case of a wind direction plate having a structure in which the wind direction plate is connected to the interlocking plate at a thin hinge portion and is integrally connected, all the rotation axes of the wind direction plate are simply provided in the blowout frame in a circular shape. With a mounting structure of a wind direction plate without any stopping means just inserted into the mounting hole, even if all the wind direction plates move with a certain moved wind direction plate, the deformation force applied to the hinge part acts However, the restoring force acts, and the angle and the moved wind direction plate return to the position before the change, and there has been a problem that the wind direction cannot be reliably changed.

However, this problem is caused by the stopping of the wind direction plate, which comprises the fixing projection 40 provided on the rotation shaft 36 side of the wind direction plate 31P and the stop groove 42 provided on the mounting hole 38P side as in the present invention. By constructing the means, it becomes possible to reliably fix the wind direction plate at the position of the changed direction.

In the embodiment, the number of the stop grooves 42 is four. However, if the number of the stop grooves 42 is further increased, it is needless to say that the direction of the wind direction plate 31 can be changed at a smaller angle. .

Numerical values set as an example of the dimensional values (unit mm) of each part constituting the wind direction device of the present invention are as follows. In FIGS. 2 to 5, a = 7.8 mm (hereinafter, mm is omitted). B), b = 8.2, c = 3.2, d = 2.
8, e = 3.4, f = 8.6, g = 6.0, h = 2.
0, i = 0.5, j = 7.9, k = 3.0, and l =
When the dimension value was set to 3.0, the wind direction plate 31 could be rotated and held in a desired direction without returning. However, if the number of wind direction plates 31 changes or the overall size of the wind direction device differs, it goes without saying that an appropriate dimension value is newly set accordingly.

The wind direction plate 31P is provided with a retaining flange 36 above the rotation shaft 37 so as not to fall downward when the wind direction plate 31P is attached to the blowout frame 13.
When the P fixing protrusion 40 is in the stop groove 42, the lower edge of the fixing protrusion 40 is hooked with the lower bottom edge of the stop groove 42, so that the lower part of the wind direction plate 31 </ b> P The detachment prevention is reliably performed together with the flange 36, and also when the fixing protrusion 40 is present on the inner peripheral surface between the stop groove 43 and the stop groove 42 of the mounting hole 38P, Since the curved portion 40 is elastically in contact with the inner peripheral surface of the mounting hole 38P, the contact force surely prevents the detachment.

Further, as shown in FIGS. 6 and 7, a plurality of fixing projections 40 are provided instead of one fixing projection 40 provided on the peripheral surface of the rotating shaft 37 of the specific wind direction plate 31P. Correspondingly, the same number of stop grooves 42 are formed on the inner peripheral surface of the mounting hole 38P at the same equiangular distance as in the case where the fixing protrusions 40 are provided. It may be provided. With this configuration, the wind direction plate 31 can be more stably held at the changed position. In addition, if the number of the stop grooves 42 is increased, the selection range of the set angle of the wind direction plate 31P is widened, and can be adapted to the demand of use.

As described above, the plurality of fixing projections 40 and the plurality of stop grooves 42 provided at the same equiangular distance respectively on the rotating shaft 37 side of the wind direction plate 31P and the mounting hole 38P thereof. In the case of the stop structure of the above, since the number of the stop means is increased and the stop is made at an equal peripheral portion, the fixing and holding can be performed more firmly and stably.

[0035]

As described above, according to the first aspect of the present invention, a plurality of resin-made wind direction plates are integrally connected to a resin interlocking plate by a thin hinge portion. By using a wind direction device, a wind direction device can be formed more easily than in the case where a dowel for coupling, in which a wind direction plate and an interlocking plate of separate parts are provided in each member, and a fitting hole in which this is fitted, is conventionally used. And the manufacturing cost can be reduced.

Further, when the integrated wind direction device is rotatably mounted on the air discharge port with the rotation axis of the wind direction plate, the elastically deformable fixing projection piece is provided on the rotation axis of the specific wind direction plate. A stopper having a simple structure in which at least one is protruded, and a fixing groove is provided in a mounting hole on the side of the blowout frame in which the rotating shaft is fitted. As a result, the wind-direction plate can be held at its rotation position, so that a stop member for rotatably supporting the wind-direction plate as in the related art is unnecessary, the number of parts is reduced, and the assemblability is improved. .

Thus, according to the wind direction device of the present invention,
There is an effect that the cost is lower than that of the conventional device and the productivity can be improved.

Further, if the fixing projection provided on the rotation axis of the wind direction plate and the stop groove formed in the mounting hole are a plurality of stop means provided at equal intervals, the wind direction rotated for changing the wind direction can be obtained. The plate can be rotated and adjusted in a wide range and finely, and can be more reliably and stably held at the selected rotation position, further improving operability, usability and durability. Can be improved.
