Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wind direction adjusting device for an air conditioner, and more particularly to a wind direction adjusting device in which driving noise of a wind direction adjusting plate of a room air conditioner for home use is improved.

[0002]

2. Description of the Related Art FIG. 5 is a partially enlarged view of an air outlet of an indoor unit of a conventional air conditioner. 6 and 7 are perspective views showing an assembling process of a vertical airflow direction adjusting plate of a conventional airflow direction adjusting device for an air conditioner.

At the indoor air outlet 19 of an indoor unit of an air conditioner such as a conventional home room air conditioner, as shown in FIG. 5, there are many small wind direction adjusting plates for changing the indoor air outlet direction to the left or right. A left-right airflow direction adjusting plate 26 that is interlocked and moved, and a long plate-like up-down airflow direction adjusting plate 17 'that changes the blowing direction up and down are provided.

As shown in FIG. 6, support shafts 18 project from the left and right ends of the vertical airflow direction adjusting plate 17 ', and one of the support shafts 18 vertically rotates the vertical airflow direction adjusting plate 17'. Attached to a motor (not shown) for moving
The other support shaft 18 is inserted into a support hole 21 as a bearing provided in the outlet side wall 20 for supporting the vertical airflow direction adjusting plate 17 'as shown in FIG.

[0005]

However, since the center of gravity of the vertical airflow direction adjusting plate 17 'is slightly deviated as described above, if the vertical airflow direction adjusting plate 17' is swung in this state, the vertical airflow direction is halfway. The movement of the center of gravity of the adjusting plate 17 'occurs, and what has been applied with a moment in the direction opposite to the motor rotation direction until then is changed to a moment in the same direction as the motor. Therefore, there is a problem in that the backlash of the motor alone and the rattling of the clearance between the motor shaft and the support shaft 18 of the vertical airflow direction adjusting plate 17 'overlap and do not swing smoothly. Therefore, the present invention provides a wind direction adjusting device for an air conditioner, which is provided with a vertical airflow direction adjusting plate which moves smoothly without any rattling even when the center of gravity is moved by constantly giving resistance to the vertical airflow direction adjusting plate during operation. It was invented for that purpose.

[0006]

In order to achieve the above object, the present invention is arranged in a blowout port for indoor air in a substantially horizontal direction and is for vertically deflecting the air blown out from the blowout port. In an air conditioner for an air conditioner that supports a vertical airflow direction adjusting plate and has a support shaft that rotates integrally with the vertical airflow direction adjusting plate, presses the support shaft from the outer peripheral direction to constantly rotate the support shaft. It is characterized in that a rotatable disc-shaped roller biased by a spring for giving resistance is provided in the vicinity of the side wall of the air outlet.

[0007]

According to the present invention, a rotatable disc-shaped roller urged by a spring is pressed against the support shaft from the outer peripheral direction of the support shaft to constantly give resistance to the rotation of the support shaft. Backlash of the wind direction adjusting plate that occurs when the center of gravity of the vehicle passes through the vertical line and rattling of the clearance between the motor shaft and the support shaft of the vertical air direction adjusting plate are prevented, and smooth rotation is always performed.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 4 is a configuration diagram showing the overall configuration of an air conditioner to which the embodiment of the present invention is applied, which is an example of a separate type air conditioner, and is separated into an outdoor unit A and an indoor unit B. ing. The outdoor unit A includes a compressor 1, an outdoor heat exchanger 2, an accumulator 3, an outdoor blower 4, a pipe 5 and the like, and a three-way valve 6 is attached to an end of the pipe 5 on the outlet side. A three-way valve 7 is attached to the inlet end of the pipe 5. The indoor unit B is provided with a dryer 8, an expansion valve 9, an indoor heat exchanger 10, an indoor blower 11 and a pipe 12, and both ends of the pipe 12 are connected to the pipe 5 of the outdoor unit A by a connecting pipe 13, Fittings 15, 16 connectable via 14 are mounted.

FIG. 1 is a perspective view of an essential part of an embodiment of an air conditioner for an air conditioner according to the present invention, FIG. 2 is a side view of an essential part of the air conditioner shown in FIG. 1, and FIG. 3 is shown in FIG. It is a principal part top view of a wind direction adjusting device.

1 to 3, the support shaft 18 fixed to the vertical airflow direction adjusting plate 17 or integrally formed with the vertical airflow direction adjusting plate 17 is the air outlet 19 of the air in the indoor unit B of the air conditioner. Support holes 21 drilled in the left and right side walls 20
And is rotatably supported by the support hole 21.
The one support shaft 18 is an electric motor (not shown) for vertically moving the vertical airflow direction adjusting plate 17 about the support shaft 18 as a fulcrum.
Is linked to. In addition, from the support hole 21 to the side wall 20
On the outer periphery of the other support shaft 18 protruding outwardly, one end 23a of the side wall 20 near the support hole 21 is rotatably attached to the other end 23b of a support piece 23 rotatably supported by a shaft 22. The attached disc-shaped roller 24 is pressed by the spring 25 loosely fitted to the shaft 22 via the support piece 23, and constantly resists the rotation of the support shaft 18.

Next, the operation of the vertical airflow direction adjusting plate will be described. The vertical airflow direction adjusting plate 17 has a constant angle by a motor (not shown) connected to the support shaft 18 so that cold air or warm air blown out from the air outlet 19 during cooling or heating is not biased to a part of the room. Repeated vertical movement of the width.
When the vertical airflow direction adjusting plate 17 is rotated by the motor and the center of gravity of the vertical airflow direction adjusting plate 17 passes through the perpendicular, the vertical airflow direction adjusting plate 17 that has been lifted by the motor until then moves up and down. Wind direction adjustment plate 1
7 It tries to rotate by its own gravity. However, the support shaft 18 fixed to or integrally formed with the vertical airflow direction adjusting plate 17
A disk-shaped roller 24, which is biased by a spring 25 via a support piece 23, is pressed against the outer periphery of the support shaft 18 and is constantly supported.
Since the resistance is added to the rotation of the
The rotation of 7 due to gravity is restricted, and the vertical airflow direction adjusting plate 17 is smoothly rotated.

[0013]

According to the present invention, the support shaft of the vertical airflow direction adjusting plate is provided with the disk-shaped roller that constantly resists the rotation of the support shaft, so that the airflow direction adjusting plate can be rotated smoothly and reliably. A wind direction adjusting device for an air conditioner that is performed can be provided.
