DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An invention according to a first aspect of the present invention is directed to a horizontal louver having a rotating shaft and a plurality of holes arranged in a row in parallel with the rotating axis, and a ring-shaped recess near the tip. A vertical louver having a pin penetrating through the hole of the horizontal louver, and an elastic cap provided with a projection that fits into the recess of the pin, and the horizontal louver is used for cleaning the air conditioner. And disassembly and assembly of the vertical louver is easy.

According to a second aspect of the present invention, in addition to the first aspect of the invention, the cap is connected with a connecting portion in accordance with the interval between the holes of the horizontal louver to integrally form a plurality of caps. This has the effect that the cap, which is a plurality of small parts, is not lost when cleaning the conditioner.

According to a third aspect of the present invention, in addition to the first aspect of the present invention, the horizontal louvers are sandwiched between the vertical louvers and the upper side of the vertical louvers integrally formed with the cap in a direction opposite to the direction below the vertical louvers. In addition, since the louver area is increased by providing the upper part of the vertical louver in the opposite direction in addition to the lower part of the vertical louver, there is an effect that a larger air volume can be changed.

An embodiment of the present invention will be described below with reference to the drawings. (Embodiment 1) FIG. 1 is a perspective view of a wind direction changing apparatus according to Embodiment 1 of the present invention, and FIG. 2 is a longitudinal sectional view taken along line AA 'of FIG. As shown in FIGS. 1 and 2, the wind direction changing device according to the first embodiment includes a horizontal louver 10 having a plurality of holes 9 in a row provided in parallel with a rotating shaft 8 and a line of the rotating shaft 8, A vertical louver lower 13 having a pin 12 penetrating through the hole 9 of the horizontal louver 10 provided with a ring-shaped recess 11 and an elastic cap 15 having a projection 14 fitted with the recess 11 and including the pin 12. It is configured.

In the above construction, the lower part 13 of the vertical louver is supported by the horizontal louver 10 when the pin 12 and the cap 15 and the recess 11 and the projection 14 are fitted to each other, and can be freely rotated to adjust the wind direction. . To disassemble the wind direction changing device, it is sufficient to pull out the elastic cap 15, which is very simple without any tools. Similarly,
For assembly, it is only necessary to fit the cap 15 on the pin 12.

(Embodiment 2) FIG. 3 is a perspective view of a wind direction changing device according to Embodiment 2 of the present invention,
Are connected at the intervals of the plurality of holes 9 of the horizontal louver 10 by a connecting portion 16 of an elastic body to integrally form a plurality.

In the above configuration, when disassembling the wind direction changing device, the cap 15, which is a small part, can be stored without being lost, and can be quickly fitted without being picked up one by one during assembly.

(Embodiment 3) FIG. 4 is a perspective view of a wind direction changing device according to Embodiment 3 of the present invention, and a horizontal louver 1 is shown.
Insert the cap 1 in the direction opposite to the lower
5 is provided with a vertical louver upper 17 having an integral structure.

In the above configuration, since the louver area is greatly increased by providing the vertical louver 17 in addition to the vertical louver lower portion 13, a larger air volume can be changed.

[0016]

As described above, according to the present invention, a horizontal louver having a rotating shaft and a row of a plurality of holes provided in parallel with the rotating axis, and a ring-shaped recess near the tip are provided. Under the vertical louver with a pin passing through the hole in the horizontal louver,
By comprising an elastic cap provided with a projection that fits into the recess of the pin, when cleaning the air conditioner, the wind direction changing device is easy to disassemble and easy to assemble. And satisfactory maintenance can be realized.

In addition, by connecting the cap with the connecting portion of the elastic body in accordance with the distance between the holes of the horizontal louver and integrally forming a plurality of caps, the cap which is a plurality of small parts when disassembled when cleaning the air conditioner. This eliminates the hassle of searching and saves the trouble of searching, and at the same time, the caps can be quickly fitted without having to take the caps one by one during assembly, reducing maintenance time.

Further, by providing the upper part of the vertical louver integrally formed with the cap in a direction opposite to the lower part of the vertical louver with the horizontal louver interposed therebetween, the upper part of the vertical louver is provided in addition to the lower part of the vertical louver, so that the louver area can be greatly increased. Therefore, more airflow can be changed in the airflow direction, and air conditioning with a uniform temperature distribution can be realized.
