Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a wind direction adjusting device provided at an air outlet of an indoor unit.

[0002]

[Prior Art]

 At the air outlet opening 1 of the indoor unit of the conventional air conditioner, as shown in FIG. 4, a plurality of wind direction plates 2 are provided with rotary shafts 3 so as to be arranged in a line and divided into two groups. The drive shaft 4 is provided at 2 at a certain distance from the rotating shaft, these are connected by a connecting plate 5, and a motor is connected to the connecting plate to periodically change the wind direction. However, especially in the corners of the room, where the cool air reaches far away from the centerline of the equipment, the use performance was not always sufficient.

[0003]

[Problems to be solved by the device]

 The present invention has been made in view of the problems of the above-described conventional example, and an object thereof is to provide an airflow direction adjusting device with a high airflow direction changing speed.

[0004]

[Means for Solving the Problems]

 In order to solve the above problems, in the present invention, a plurality of wind direction plates are provided in the air outlet opening of the indoor unit, and the wind direction plates are divided into left and right and connected by connecting plates to form left and right wind direction plates. The oscillating plate that is swingably supported on the oscillating plate and the two oscillating plates whose one end is connected to the oscillating plate, and the other end of the oscillating plate is connected to each of the connecting plates. The drive plate is provided with a long hole in the left-right direction, and the drive pin that is eccentrically installed on the drive disk driven by the motor is positioned.The rotation of the motor causes the left-right airflow direction plate to move in opposite directions. It is characterized by being rotated.

[0005]

[Action]

 The frequency of wind reaching the position away from the center line of the device becomes large.

[0006]

【Example】

 Hereinafter, an embodiment of an air conditioner according to the present invention will be described with reference to FIGS. 1 to 3. FIG. 1 is a plan view of an air blowing opening 1 of an indoor unit, showing the wind direction adjusting device by cutting off the upper part, FIG. 2 is an enlarged plan view of the main part thereof, and FIG. 3 is a rear view. The wind direction plate 2 is a plate body made of a synthetic resin or the like and has a rotating shaft 3, and a drive shaft 4 is hung down by cutting out a lower rear portion thereof. As shown in FIG. There is. The connecting plate 5 is an elongated plate body having a plurality of holes formed at equal intervals, and the drive shaft 4 is inserted into each hole to connect a plurality of left and right wind direction plates 2 to form left and right wind direction plates. ing. The rocking plate 6 is a member arranged in the front-rear direction at the center, has a long hole 6a in the left-right direction at one end, and is guided by a guide plate 1a standing on the bottom of the opening 1 with a guide groove 6b on the side surface. It can swing back and forth. A drive pin 7c, which is eccentrically provided upright on a rotating disk 7b rotated by a motor 7a of a drive unit 7 shown by a chain double-dashed line in FIG. 3, is located in the elongated hole 6a. The inner ends of the left and right connecting plates and the rocking plate 6 are connected by a drive plate 8. The elongated hole 6a may be a U-shaped recess opened in the left-right direction by cutting off the end as in the embodiment.

Therefore, in FIG. 2, when the drive unit 7 operates, the drive pin 7c moves in the elongated hole 6a to retract the swing plate 6. As a result, the connecting portion of the drive plate 8 with the oscillating plate 6 moves rearward to move the connecting plate 5 connected to the other end inward, and the wind direction plate 2 is moved to the left and right as shown by the dotted line. Rotate outwards from each other. By one rotation of the driving disc 7b, the right wind direction plate rotates from the center to the right end and returns to the center again, and the left wind direction plate reciprocates leftward. In the conventional example, it takes time for the wind direction plate to rotate from the left end to the right end, but since the one according to the present invention operates symmetrically on the left and right, the number of sweeps is reduced when the rotation speed of the wind direction plate is designed to be the same. Doubled.

[0008]

[Effect of the device]

 As described above, in the present invention, the blowing direction is divided into two parts by reversing the rotating direction of the left and right wind direction plates, so that it is easy to double the number of changes in the wind direction, especially away from the center line of the instrument. It is possible to produce the effect of blowing air to the position at short intervals.
