Description

[Detailed description of the invention] (b) Industrial application fields INDUSTRIAL APPLICATION This invention is utilized in the field of air conditioning.

The present invention relates to a wind direction changing device for an air conditioner,
More specifically, the present invention relates to a so-called swing-type wind direction changing device that is operated via a blade at a conditioned air outlet of an air conditioner.

(B) Prior Art As shown in FIG. 3, a conventional swing type wind direction changing device includes a fixed blade 24 and a movable vertical blade 26 disposed on a connecting plate 30.
The reciprocating motion of the movable vertical blade 26 swings and the direction of the blade alternately changes. However, the orientation angle of the blades is constant.

(c) Problems to be solved by the invention In such a conventional device, in order to prevent a draft feeling caused by uneven temperature and airflow during heating operation, the operation of the wind direction changing device is stopped. There is. In that case, as mentioned above, the direction of the movable vertical blades 26 is constant, so the wind direction and blowing width are limited, making it impossible to blow wide (e.g. 80 to 90 degrees), resulting in uneven indoor temperature distribution. Some shortcomings have been pointed out.

An object of the present invention is to make it possible to manually change the direction and angle of the movable vertical blades individually or in groups when the wind direction changing device is stopped, that is, when the reciprocating movement of the connecting plate is stopped. An object of the present invention is to provide a wind direction changing device for an air conditioner to which a wind direction changing mechanism is added. This improves fixing of the blowout angle when the wind direction changing device is stopped.

(d) Means for solving the problem The above object is to provide a blower for a plurality of movable vertical blades disposed via one connecting plate and a drive device for horizontally reciprocating the connecting plate in the left and right direction. This can be achieved by constructing a wind direction changing device for an air conditioner provided at the outlet so that each movable vertical blade can individually change the air wind direction and angle via a support shaft.

It also has a plurality of divided connecting plates, a support shaft arranged on the divided connecting plates, and a support shaft rotatably attached to the main body of the aircraft, and a plurality of movable parts arranged for each divided connecting plate. A connecting means that connects the vertical blades and each divided connecting plate by separating or overlapping them, and allowing the direction of the movable vertical blades to be changed depending on the manner of separation or overlapping, and connecting the plurality of divided connecting plates horizontally. This can be achieved by equipping the blower outlet with a drive device that reciprocates in the left-right direction and changing the direction of the movable vertical blades to which each divided connecting plate belongs.

(E) Function Conventionally, when the movable vertical blades reciprocate through the connecting plate, each movable vertical blade becomes parallel to each other and changes direction, and when the reciprocating movement is stopped, the direction of each movable vertical blade changes. The orientation direction remains constant.

In contrast, in the present invention, when the reciprocating movement of the connecting plate is stopped, the directions of the plurality of movable vertical blades can be manually changed individually, or the directions of each group can be manually changed, so that the movement is harmonized. The air blowing angle can be freely changed, and a wide range of wind direction angles can be obtained as a whole, or adjustments can be made such as concentrating the blowing air in a certain direction.
