[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device capable of easily changing the swinging angle of the air outlet of an air conditioner.

[0002]

2. Description of the Related Art In order to diffuse cold air in an air conditioner and blow it out, an air outlet or an air outlet duct is swung within a predetermined angle, so-called swinging.

[0003]

In a conventional automatic swinging apparatus, a first link which is rotationally driven by a motor and a second link which is connected to the outlet side frame are pivotally attached by a single shaft. The rotary motion is converted into a reciprocating motion and transmitted to the outlet side frame. The swinging angle is changed by changing the pivotal position of the first link with respect to the second link. This is done by pin engagement at a plurality of positions on the first link that are different in length from the motor shaft. The second stop hole
The position of this pin locking hole is changed by removing the pin that serves as the pivot with the link. Since it is a child, it takes time to adjust the swing angle. The present invention aims to easily change the angle with one touch.

SUMMARY OF THE INVENTION The present invention has been made to achieve the above-mentioned object, and a tip of a second link pivotally attached to a first link rotated by a motor is attached to an outlet side frame. The gist of the invention is that the switching lever is pivotally mounted so that it can be swung freely and pivotally locked.

[0005]

Since the tip of the second link pivotally attached to the tip of the first link that is rotationally driven by the motor is attached to the outlet side frame via the switch lever, only this switch lever is operated. Then, the second link length will be adjusted,
The swing angle of the outlet frame can be easily changed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to illustrated embodiments. In the figure, reference numeral 1 is a drive motor, and one end of a first link 2 is locked to the motor shaft, and one end of a second link 3 is pivotally attached to the tip of the first link when the motor 1 is driven. As shown in FIG. 2, this pivotal connection is such that a first bush 5 is fitted to a shaft 4 planted in a first link, and a second bush 6 made of synthetic resin is fitted to the first bush 5. The second bush 6 is fitted in the hole of the second link 3, and a nut 8 is screwed to the shaft 4 via a washer 7 made of resin.
Can be pivoted freely.

Reference numeral 9 denotes an outlet side frame provided with an outlet grill. A bracket is provided on a part of the frame 9, and a part of the switching lever 10, for example, a central portion is provided with a shaft 11 as shown in the figure. In addition to pivotally pivoting, one end of the switching lever 10 and the end of the second link 3 are pivotally pivoted by a shaft 12. The pivotal attachment by the shaft 12 interposes a bush made of synthetic resin similarly to the pivotal attachment part of the first and second links by the shaft 4 to improve the wear resistance of the pivotal attachment part and to make it swing smoothly. Do like this.

The switching lever 10 is pivotally mounted at two different points on the frame side and the second link side. The switching lever 10 is swung about the frame side shaft 11, that is, the swing angle is changed. When performing, the relative position is determined by changing the distance between the pivot shaft 12 and the central shaft of the frame 9 with respect to the second link, and this is shown in FIG. When the frame center O, the length of the first link are r, and the distance between the frame center axis O and the second link axis 12 is L, the length L of the first link and the frame center axis O are invariable. By swinging the switching lever, the distance L changes to L3, L2, L1. At this time, L3, L2, L
The angle between 1 and a straight line passing through the central axis O is θ3, θ2, θ
It changes to 1 and the swing angle changes accordingly.

[0009]

According to the present invention, the tip end of the second link pivotally attached to the first link rotated by the motor is pivotally attached to the switching lever pivotally attached to the outlet side frame. Since it is locked, the swing angle of the outlet side frame is adjusted by the angle at which the switching lever is swung, which has the advantage that the swing angle of the outlet can be easily adjusted.
