BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner outlet structure capable of generating a fluctuating air flow so that the air blown out from an air conditioner approaches a natural wind.

[0002]

2. Description of the Related Art In order to change the wind blown from an air conditioner to bring the indoor air environment closer to nature, a blade is attached to the air outlet of the blower duct, and the angle of this blade is changed to change the wind direction. , There is one that changes the wind direction by making the outlet itself driveable. Further, there are ones that change the rotational movement of the air conditioning fan or change the wind force by narrowing the blower opening to change the diameter.

[0003]

However, the above-mentioned means for changing the wind direction or changing the wind force cannot sufficiently attenuate the velocity of the air jetted from the air outlet of the air conditioner, and it is temporarily strong. The wind can only blow out, or can only generate artificial wind that periodically blows strongly. For this reason, it may cause discomfort to people or adversely affect the human body. Further, in order to apply fluctuations to air and the like by applying the above means to a high level, drive control equipment for changing the rotation of the fan and the direction of the blades of the air outlet and the like is necessary, which is a problem that cannot be easily done.

The present invention has been made in order to solve these problems, and an object thereof is to provide an air conditioning outlet structure capable of sending a naturally fluctuating wind into a room.

[0005]

According to the air-conditioning outlet structure of the present invention, one opening of a cylindrical body is attached to a blower duct of an air conditioner, and an outer circular edge is provided on the circumference of the other opening of the cylindrical body. A large-circle pan that is curved inward in the air blowing direction is attached, and a cylindrical support that circumscribes the inner peripheral surface of the pan is provided inside the cylindrical body.The cylindrical support is a cylinder driven by a drive motor that is attached outside the cylindrical body. It has a structure that makes a reciprocating linear motion in the axial direction of the body and a rotational motion in the circumferential direction.A plurality of support rods are attached to the opening of the cylindrical support on the air blowing side in parallel to the duct, and directed toward the duct side. A small circular airflow diffusion plate formed in a convex shape is fixed by a support rod at a position eccentric from the axial center of the cylindrical body.

Further, as the support rod, one formed of a screw rod is used, and it is preferable to have a structure capable of variably adjusting the attachment length of the support rod to the air flow diffusion plate.

[0007]

In the above air conditioning outlet structure, the drive motor causes the cylindrical support to make a reciprocating linear motion in the axial direction of the cylinder and a rotational motion in the circumferential direction. Along with these movements, the airflow diffuser plate fixed to the support rod moves in a complicated manner.

When the air jetted from the outlet of the duct collides with the airflow diffusion plate, the colliding air creates various airflow distributions laterally corresponding to the shape of the surface of the airflow diffusion plate. Then, the airflow received by the pan around the air outlet is diffused into the room.

Here, the reciprocating linear movement of the cylindrical support changes the distance between the opening and the airflow diffusion plate, and changes the main flow of the airflow with respect to the movement direction of the airflow diffusion plate. Further, as the cylindrical support rotates in the circumferential direction, the airflow diffuser plate performs an eccentric rotational movement to generate an airflow accompanied with rotation, thereby forming a complicated airflow distribution with a three-dimensional change. .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of an air conditioning outlet structure according to the present invention will be described below with reference to FIGS. The blowout structure of the air blown from the blower fan of the air conditioner that adjusts the indoor air environment through the duct 1 blows out the air blown from the air conditioner into a fluctuating natural wind. is there.

A large circular shape in which one opening of a cylindrical body 2 is connected to the blower opening of the duct 1 and the vicinity of the outer circular edge is curved inward in the blowing direction on the circumference of the other opening of the cylindrical body 2. Bread 3
Is attached.

Inside the cylindrical body 2, there is always provided a cylindrical support 4 which moves in contact with the inner peripheral surface thereof. The cylindrical support 4 has a structure in which a driving motor 5 mounted outside the cylindrical body 2 makes a reciprocating linear motion in the axial direction of the cylindrical body 2 and a rotational motion in the circumferential direction. For example, a zoom mechanism of a telephoto lens that projects with rotation of a motor is used.

Three support rods 6 are attached to the opening of the cylindrical support 4 on the side of the blowing direction so as to project in parallel to the axis of the cylindrical body 2 and to be spaced at appropriate intervals. On these support rods 6, a small circular airflow diffusion plate 7 that is curved in a convex shape toward the duct 1 side is fixed at a position eccentric from the axis of the cylindrical body 2.

Here, the support rod 6 is formed of a screw rod, and the attachment length of the support rod 6 to the air flow diffusion plate 7 is variably adjusted to change the attachment angle of the air flow diffusion plate 7, or the air flow diffusion plate 7 is simplified. To be able to exchange.

The shape and form of the surface of the air flow diffusion plate 7 on the duct 1 side is not limited to a smooth streamlined shape, but for example,
A complicated air flow distribution can be created by making it porous or by providing irregularities.

[0016]

In the air-conditioning air outlet structure of the present invention, the airflow diffuser plate makes a reciprocating linear motion and an eccentric rotary motion with the cylindrical support that is driven by the drive motor. As a result, a fluctuating natural wind can be jetted into the room from the opening, and the indoor air environment can be made soft and have a pleasant breeze. Further, if a large number of the air outlet structures are arranged, a combined effect of fluctuating airflow distribution can be expected, and a more comfortable indoor air environment can be provided.
