2. Description of the Related Art As a generally used wind direction changing device for an air conditioner, two upper and lower wind direction changing plates are arranged in parallel at an air outlet and a drive motor is connected to one end of the lower wind direction changing plate. The other end of the lower wind direction changing plate and the other end of the upper wind direction changing plate are linked by a gear mechanism, which is an automatic system.

When the wind direction changing device is operated, a pulse motor as a drive motor is driven by operating a remote switch so that a desired wind direction is obtained.

On the other hand, there is a so-called manual system in which the user directly changes the wind direction changing plate by hand without depending on the drive motor according to the user's preference.

[0005]

However, it has been conventionally difficult to change the specifications between the automatic system and the manual system at the time of delivery or after delivery to the user, which is very inconvenient and uneconomical in terms of sharing parts. there were.

[0006] That is, the conventional auto system and the manual system have significant structural differences in the shape of the wind direction changing plate itself, the method of fixing the wind direction changing plate itself, and the method of manually operating the wind direction changing plate. .

For example, in order to change the operation mode from the auto mode to the manual mode, the drive motor is simply removed and a manual mechanism is attached to attempt to operate the wind direction changing plate manually. It was very difficult to operate the wind direction change board with a sense.

Therefore, a dedicated wind direction changing device for each of the automatic system and the manual system has been prepared, and the entire system has been conventionally replaced.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a wind direction changing device for an air conditioner in which a change between an automatic system and a manual system can be realized by minimal change of parts.

Reference numerals 16A and 16B denote heat exchangers, reference numeral 17 denotes a cross flow fan, and reference numeral 18 denotes a drain pan. Reference numeral 19 denotes a locking piece formed on the upper rear surface of the air conditioner body 1, which is locked by engaging with an engaging portion 21 formed on a mounting plate 20 fixed to the indoor wall. ing.

FIG. 3 schematically shows the entirety of the wind direction changing device. The wind direction changing device 22A is provided with the above-described upper wind direction changing plate 4 and lower wind direction changing plate 5 at an air outlet 23 opening in the air conditioner main body 1.
Are arranged in parallel, and the shafts 4a and 5a on the other end side, respectively.
Are the conduction gear 24a, the intermediate gear 24b, and the conduction gear 2
4c and is attached to the side plate 25a.

Further, a motor drive mechanism 27 is attached to bosses 26a and 26b formed integrally with the side plate 25b on one end side by attaching screws 28.

That is, the motor drive mechanism 27 is
Fixing plate 2 attached to screws 6a and 26b by screws 28
9 and a rotating shaft 30a of the driving motor 30 pass through a through hole 29a formed in the fixed plate 29, and a tip end of the rotating shaft 30a is connected to the lower wind direction changing plate 5.
And is integrated with a shaft hole formed in the shaft 5b. Reference numeral 35 denotes a bearing for the shaft 4b of the upper and upper wind direction changing plate 4.

In the wind direction changing device 22A having the above structure, when the drive motor 30 is driven, the rotation of the rotating shaft 30a causes the shaft 5b of the lower wind direction changing plate 5 to rotate, thereby blowing out the lower wind direction changing plate 5. While changing the wind direction, the shaft 5a on the other end side
The transmission mechanism 24 is rotated via.

Accordingly, the transmission mechanism 24 causes the shaft 4
The upper wind direction changing plate 4 is rotated so that the rotational force of the drive motor 30 is transmitted to a and synchronized with the lower wind direction changing plate 5 to change the upper wind direction.

On the other hand, FIG. 4 shows a wind direction changing device 22B of a manual type. In FIG. 4, the wind direction changing device 2B shown in FIG.
The main difference from 2A is that a manual rotation mechanism 31 is attached instead of the motor drive mechanism 27.

Here, the configuration of the manual rotation mechanism 31 will be described in detail with reference to FIGS.
The fixing plate 32 is fixed to the bosses 26a and 26b having the same configuration as that described with reference to FIG. A guide ring 34, which is a part of an annular cylinder, that guides the rotating part 33 is formed on the fixed plate 32 so as to protrude therefrom.
Protrusions 34a and 34b are formed at appropriate locations on the inner peripheral wall of the rim. On the other hand, in response to this, the rotation unit 33
It is rotatable inside the guide ring 34, and its peripheral wall has
A projecting engagement recess 33a is formed.

Further, as shown in FIG. 7, the rotating part 33 has the same configuration as the connecting hole formed on the shaft 5b of the lower wind direction changing plate 5 described with reference to FIG. It fits into the connection hole 5c and is rotatable as a single body.

In this configuration, for example, when the lower wind direction changing plate 5 is gripped and operated by hand, the direction of the lower wind direction changing plate 5 is changed with the shafts 5a and 5b as fulcrums. At this time, axis 5
b and the rotating shaft 33b interlock, and the rotating part 33 rotates the guide ring 34. On one end side, first, the guide ring 34
Is engaged with the engaging concave portion 33a of the rotating portion 33.

Therefore, the rotation part 33 is prevented from rotating clockwise, the upper wind direction changing plate 4 and the lower wind direction changing plate 5 are fully closed, and the operator can be fully closed by hand feeling. Figure out.

Next, in order to change the wind direction between the upper wind direction changing plate 4 and the lower wind direction changing plate 5, the lower wind direction changing plate 5 is operated by hand so that the opening is enlarged. Rotates in the counterclockwise direction of the arrow shown in FIG. 6 to engage the engaging portion 34b of the guide ring 34 with the engaging recess 3 of the rotating shaft 33b.
3a is engaged and the movement is temporarily stopped.

Thus, the upper wind direction changing plate 4 and the lower wind direction changing plate 5 reach the branch point of cooling and heating by the operation of the hand.
And the wind direction is changed.

As can be seen by comparing FIGS. 3 and 4, the wind direction changing device 22A and the wind direction changing device 22B differ only in the configuration of the motor drive mechanism 27 and the manual rotation mechanism 31. They have exactly the same configuration. For this reason, in the case of the automatic method, after the mounting screw 28 is loosened and the motor drive mechanism 27 is removed, the manual rotating mechanism 31 is instead fixed to the bosses 26a and 26b by the mounting screw 28, and the rotating shaft 33b is connected to the shaft 5b. By connecting to the connection hole 5c formed in the above, a manual method can be adopted.

In this case, operating the lower wind direction change plate 5 so as to obtain a desired wind direction by taking advantage of manual feeling may not be easy due to play and slippage of the gears. The mechanism 31 has a frictional resistance substantially equal to the torque sense of the motor drive mechanism 27 to facilitate the operation. Moreover, the locking portions 34a, 3 of the guide ring 34
Since the positioning is performed at a predetermined position by the engagement recess 33a of the rotating portion 33 with the engagement portion 4b, the manual operation is very convenient.

Now, in the case of the manual system, after the mounting screw 28 is loosened and the manual rotation mechanism 31 is removed, the motor drive mechanism 27 is mounted instead, and the operation is changed to the automatic system by a very simple operation. be able to.

Accordingly, if the manual rotation mechanism 31 or the motor drive mechanism 27 is prepared, it is not necessary to replace the entire wind direction changing device as in the prior art, which is extremely convenient.
And it will be economical.

As described above, according to the present invention, in a wind direction changing device for an air conditioner in which a plurality of wind direction changing plates are juxtaposed in parallel from one end to the other end of the air outlet,
The axes of the plurality of wind direction change plates are connected via a transmission mechanism for operating the plurality of wind direction change plates in synchronization,
On the other end side, the axis of one of the plurality of wind direction change plates is driven by a manual rotation mechanism that operates when the wind direction change plate is manually operated or a motor drive that is operated when the wind direction change plate is operated by a motor. An attachment portion that allows any one of the mechanisms to be attached is provided. Therefore, switching between the so-called automatic type and the manual type can be realized by a simple operation of simply changing the mounting portion at the other end to a manual rotating mechanism or a motor driving mechanism, and is economically and extremely convenient in terms of sharing parts. It is.
