DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wind direction changing device capable of independently opening and closing a plurality of wind direction changing blades provided on a decorative panel.

[0002]

2. Description of the Related Art Generally, air outlets are provided along four sides of a decorative panel constituting an air conditioner, and wind direction changing blades are provided at each of the air outlets, and each wind direction changing blade is opened and closed by a motor. Known wind direction change devices are known.

In this type, since the wind direction changing blades are provided along the four sides of the decorative panel, their drive shafts are orthogonal to each other, and all the wind direction changing blades are simultaneously opened and closed by a single motor. In this case, the respective drive shafts must be connected by a universal joint having a tilt angle of, for example, 45 °.

In recent years, there has been proposed a type in which four wind direction changing blades provided at each outlet are independently opened and closed by four motors (for example, Japanese Utility Model Publication No. 63-4897). Gazette).

[0005]

When four motors are arranged, it is desirable to arrange the motors at the four corners of the decorative panel to maintain the weight balance of the decorative panel evenly. If it is distributed to the four corners, there is a problem that the number of inspection points increases at the time of service inspection, making inspection difficult. On the other hand, if the motors are installed collectively, inspection becomes easier, but this requires a plurality of motors to be housed in a narrow space, and there is a problem that the support structure such as a universal joint becomes complicated. .

Accordingly, an object of the present invention is to solve the above-mentioned problems of the prior art, to arrange the motors collectively, and to simplify the support structure of the universal joint. Is to provide.

[0007]

In order to achieve the above object, according to the present invention, wind direction changing blades are respectively arranged at air outlets provided along four sides of a decorative panel, and each of the wind direction changing blades is driven by a motor. In a wind direction changing device that opens and closes independently, two motors of adjacent wind direction changing blades are arranged at one corner of a decorative panel, and an output shaft of each motor is connected to a drive shaft of each wind direction changing blade via a power transmission mechanism. And, the shafts of adjacent power transmission mechanisms are connected by a connecting sleeve.

[0008]

According to the present invention, the output shafts of the two motors are respectively connected to the drive shafts of the wind direction changing blades via the power transmission mechanism, and the two power transmission mechanisms are arranged at one corner of the decorative panel. When the power transmission mechanism is normally supported at two points, the adjacent power transmission mechanisms are connected by a connecting sleeve. Therefore, it is only necessary to use a bearing at only one support part, and the support structure is simplified accordingly. Can be

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS.

In FIG. 1, reference numeral 1 denotes a decorative panel. The decorative panel 1 is generally attached to the lower surface of a unit body embedded in a ceiling to constitute an air conditioner of a ceiling embedded type. A suction port 3 for taking in room air is provided at the center of the decorative panel 1, and the air after heat exchange is introduced into the room along the four sides of the decorative panel 1 so as to surround the suction port 3. Outlets 5a, 5b, 5c, 5d for blowing out
Is provided.

The air outlets 5a, 5b, 5c, 5d are provided with wind direction changing blades 7a, 7b, 7c, 7d, respectively.
Each of the wind direction changing blades 7a, 7b, 7c, 7d has a motor 9a, 9b, 9c,
9d are connected, and each motor 9 is dispersedly arranged at two corners of the decorative panel 1.

That is, in this embodiment, when arranging the motors 9a and 9b at the corners of the decorative panel 1, the adjacent wind direction changing blades 7a and 7b are opened and closed so that service inspection after the installation of the air conditioner is easy. Motors 9a and 9b
Are arranged collectively in two places.

FIG. 2 shows an enlarged view of a connecting portion between the motors 9a and 9b (FIG. 4 is an enlarged view of that portion). The two motors 9a and 9b are collectively arranged at one corner of the decorative panel 1, and the motors 9a and 9b are fixed to the back surface 1a of the decorative panel 1 via the motor bracket 11, respectively.
The motors 9a, 9b and the wind direction changing blades 7a, 7b are connected via a power transmission mechanism 13, and the power transmission mechanism 13 controls the rotational movement of the motors 9a, 9b by the wind direction changing blades 7.
a, 7b. That is, the power transmission mechanism 13 includes a crank 15 fixed to the output shafts of the motors 9a and 9b, a swing plate 17 connected to a crank pin 15a of the crank 15, and a swing plate 17
And a universal joint 19 connected to
The universal joint 19 includes a driving body 19a and a driven body 19b, and the driven body 19b is connected to the wind direction changing blades 7a and 7b.

According to this embodiment, when the power transmission mechanism 13 is supported on the back surface 1a of the decorative panel 1, the driven body 1
A bearing 21 for rotatably supporting the bearing 9b and a connecting sleeve 23 for connecting adjacent driving bodies 19a are used. As shown in FIG. 3, the connecting sleeve 23 has a hollow shape, and the driving bodies 19a adjacent to each other are provided on both sides thereof.
Are rotatably fitted with each other. Drive body 1
The shaft 9a has a different diameter from the step 31. The small-diameter shaft 33 is fitted into the hollow of the connecting sleeve 23 as described above, and the large-diameter shaft 35 is connected to the rocking body 17. Have been.

Next, the opening and closing operation of the wind direction changing blade 7 will be described.

When the motors 9a and 9b are driven, the crank 15 rotates, and the swing plate 17 swings via a crank pin 15a provided eccentrically to the crank 15. The oscillating motion of the oscillating plate 17 is a universal joint 19
The rotational motion of the driven member 19a is converted into the rotational motion of the driven member 19b by a known means. Thereby, the drive shafts of the wind direction changing blades 7a and 7b rotate, and the wind direction is changed.

Thus, according to this embodiment, the structure for supporting the power transmission mechanism 13 is simplified despite the two motors 9a and 9b being arranged at one corner of the decorative panel 1. Is done. That is, according to this, the power transmission mechanism 1
3 is supported, only one bearing 21 needs to be used.
So that the driving body 19a
This eliminates the need for a bearing for supporting the support, and can greatly simplify the support structure.

The motors 9a, 9b of the decorative panel 1
Motors 9c and 9d are arranged in a corner (not shown) on the opposite side to the corner where is disposed in the same relationship as motors 9a and 9b.

[0019]

As is apparent from the above description, according to the present invention, two motors of adjacent wind direction changing blades are arranged at one corner of the decorative panel, and the output shaft of each motor is connected via the power transmission mechanism. Connected to the drive shaft of each wind direction changing blade, and the adjacent shafts of the power transmission mechanism are connected by a connection sleeve.
If the support structure of the power transmission mechanism is a two-point support structure, it is necessary to use a bearing only at one point of the support part by connecting with the connecting sleeve, and the support structure is simplified by that much. be able to.
