Abstract

PROBLEM TO BE SOLVED: To obtain a ceiling diffuser which can regulate indoor air flow distribution easily. SOLUTION: The ceiling diffuser comprises a diffuser body 1, and an air direction regulator 2 for diffusing supply air flow from the diffuser body 1 radially. The ceiling diffuser further comprises a motor 3 for driving the air direction regulator 2 in the axial direction A of the air hole of the diffuser body 1.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ceiling diffuser.

[0002]

2. Description of the Related Art A conventional ceiling diffuser, for example, an anemo-type outlet, has been used to manually adjust the position of a cone for adjusting the wind direction inside the ceiling diffuser.

[0003]

Therefore, there is a problem that the adjustment work is troublesome, and it takes much time and effort in places where the ceiling is hard to reach.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention comprises an outlet main body and a wind direction adjusting member for radially diffusing an air flow blown from the outlet main body. A motor for driving the body in the axial direction of the air hole of the outlet body is provided. In addition, a controller is provided for controlling the motor drive so that the wind direction adjusting body continuously reciprocates and intermittently reciprocates in the direction of the air hole axis.

[0005]

1 and 2 show an embodiment of the present invention. This ceiling diffuser comprises an outlet main body 1 and a wind direction adjuster 2 for radially diffusing the air flow from the outlet main body 1. FIG.
And a motor 3 for driving the wind direction adjusting body 2 in the air hole axial direction A of the outlet main body 1 and a remote control switch (not shown) for operating the motor 3. The white arrow indicates the airflow direction.

The outlet main body 1 has a cylindrical shape as a whole, and an air hole 4 expands (diameter expands) toward the tip end (blow-out direction).
An air duct 6 is connected to the base end of the air hole 4. The wind direction adjuster 2 expands (expands in diameter) in the direction of the tip (blow-out direction).
And a plurality of concentric annular blades 5 which are disposed at the front end widening portion of the air hole 4. The wind direction adjusting body 2 is connected to a drive shaft of the motor 3 by a connecting member or the like, and the motor 3 is fixed in the outlet main body 1.

The remote control switch is operable at hand by wire or wireless, and the drive shaft of the motor 3 is driven in either the distal direction or the proximal direction by operating the switch. At a desired position. For example, according to the difference between the room temperature and the airflow temperature,
As shown in FIG. 3, the airflow direction adjusting body 2 is directed toward the front end (in the blowing direction) at the time of heating so that the blown air does not stay on the ceiling surface due to buoyancy and sufficiently reaches the floor surface, and vice versa during cooling. .

Reference numeral 7 denotes a controller which controls the driving of the motor 3 so that the wind direction adjusting member 2 reciprocates continuously and intermittently in the air hole axial direction A. The continuous reciprocation and intermittent reciprocation of the wind direction adjuster 2 are configured to be switchable by the remote control switch.

The ceiling diffuser of the present invention can be applied to a pan-type outlet other than the anemo-type outlet. Further, the widened end portion of the outlet main body 1 and the wind direction adjuster 2 may be formed in a rectangular shape.

[0010]

According to the first aspect of the present invention, the operation of the motor 3 allows the indoor airflow distribution to be freely and easily adjusted and changed for cooling or heating. According to the second aspect of the invention, it is possible to prevent the bias and stagnation of the air by changing the blowing direction of the airflow continuously or indirectly, and to achieve a uniform airflow distribution in the room.
