Description

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, an air outlet is provided along each of four sides of a decorative panel that constitutes an air conditioner, and each air outlet is provided with a wind direction changing blade, and each wind direction changing blade is opened and closed by a motor. There are known wind direction changing devices.

In this type, since the wind direction changing blades are provided along the four sides of the decorative panel, the drive axes thereof 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 universal joints having an inclination angle of 45 °, for example.

By the way, in recent years, there has been proposed one 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). Bulletin).

[0005]

When arranging four motors, it is desirable to arrange the motors at the four corners of the decorative panel to maintain the weight balance of the decorative panel even. If they are dispersed in the four corners, there will be a problem that the number of inspection points will increase during service inspection, making inspection difficult. On the other hand, if the motors are installed together, the inspection will be 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. ..

Therefore, an object of the present invention is to solve the above-mentioned problems of the conventional technique, to arrange the motors together, and to simplify the supporting structure of the universal joint. To provide.

[0007]

In order to achieve the above object, the present invention has wind direction changing blades arranged at air outlets provided along four sides of a decorative panel, and each wind direction changing blade is 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 the output shaft of each motor is connected to the drive shaft of each wind direction changing blade via a power transmission mechanism. However, 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 through the power transmission mechanism, and the two power transmission mechanisms are arranged together at one corner of the decorative panel. In this case, if the two-point support is usually used, the adjacent power transmission mechanisms are connected by the connecting sleeve, so that it is sufficient to use the bearing only for the one-point support portion, and the support structure can be simplified accordingly. Can be converted.

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

In FIG. 1, reference numeral 1 denotes a decorative panel. This decorative panel 1 is generally attached to the lower surface of a unit body that is embedded in the ceiling to form a ceiling-embedded air conditioner. A suction port 3 for taking in indoor 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. Air outlets 5a, 5b, 5c, 5d for blowing out
Is provided.

The air outlets 5a, 5b, 5c and 5d are provided with wind direction changing blades 7a, 7b, 7c and 7d, respectively.
The wind direction changing blades 7a, 7b, 7c, 7d are individually provided with motors 9a, 9b, 9c, so that they can be opened and closed independently.
9d are connected, and the motors 9 are arranged in two corners of the decorative panel 1 in a dispersed manner.

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

FIG. 2 shows the connecting portion of the motors 9a and 9b in an enlarged manner (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 a motor bracket 11, respectively.
The motors 9a and 9b and the wind direction changing blades 7a and 7b are connected to each other via a power transmission mechanism 13, and the power transmission mechanism 13 controls the rotational movement of the motors 9a and 9b.
It is configured to be converted into the rotational movement of a and 7b. That is, the power transmission mechanism 13 includes the crank 15 fixed to the output shafts of the motors 9a and 9b, the swing plate 17 connected to the crank pin 15a of the crank 15, and the swing plate 17.
Consisting of a universal joint 19 connected to
The universal joint 19 comprises a driving body 19a and a driven body 19b, and the driven body 19b is connected to the wind direction changing vanes 7a, 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 that rotatably supports 9b and a connecting sleeve 23 that connects 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.
The shafts of the two are rotatably fitted together. The driving body 1
The shaft of 9a has a different diameter with the step portion 31 as a boundary, the small-diameter shaft portion 33 is fitted into the hollow of the connecting sleeve 23 as described above, and the large-diameter shaft portion 35 is connected to the rocking body 17. Has been done.

Next, the opening / 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 rocking plate 17 rocks via the crank pin 15a provided eccentrically on the crank 15. The swing motion of the swing plate 17 is caused by the universal joint 19
Is converted into the rotational movement of the driven body 19a, and this rotational movement is converted into the rotational movement of the driven body 19b by a known means. As a result, the drive shafts of the wind direction changing vanes 7a and 7b rotate, and the wind direction is changed.

According to this embodiment, however, the structure for supporting the power transmission mechanism 13 is simplified even though the two motors 9a and 9b are collectively arranged at one corner of the decorative panel 1. To be done. That is, according to this, the power transmission mechanism 1
In order to support 3, it is only necessary to use one bearing 21, and in the other, the adjacent driving bodies 19a are connected to the connecting sleeve 23.
Since it is supported by connecting with,
Since a bearing for supporting the support is unnecessary, the support structure can be extremely simplified.

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

[0019]

As is apparent from the above description, according to the present invention, two motors of adjoining wind direction changing vanes are arranged at one corner of the decorative panel, and the output shaft of each motor is connected via the power transmission mechanism. Since it is connected to the drive shaft of each wind direction changing blade and the shafts of the adjacent power transmission mechanisms are connected by the connecting sleeve,
If the support structure of the power transmission mechanism is a two-point support structure, since it is connected by a connecting sleeve, it is only necessary to use a bearing for the support portion at one point, and the support structure is simplified accordingly. be able to.
