Thus, the blow-out port includes i) a blow-out vane installed in the blow-out port fixed in a fixed direction, ii) a blow-out vane in which the blow-out direction is manually adjusted, and iii) a blow-out vane. There is one that automatically changes the direction at a fixed cycle, and sets the required temperature and air volume to heat and cool a small local space.

(Problems to be Solved by the Invention) However, in the conventional air conditioner, the direction of the blowing blades mounted on the air outlet is adjusted, and air flows in a fixed direction, so that warm air is blown to a fixed part of the human body. Cold wind hits.

In addition, the method of changing the air flow while automatically changing the angle of the blowing blades at a fixed cycle has the effect of making the temperature distribution in the room uniform, but the variable blowing blades change at a fixed cycle, so May predict the direction of the hot and cold air coming next,
The airflow is extremely strong and weak, causing discomfort.

In this way, it is not preferable for the local heating and cooling of a small space to heat and cool air to be blown out in a fixed direction or to change the blowing direction at a fixed cycle, and it cannot be said that it is a good environment.

The present invention has been proposed in view of the above problems of the prior art, and an object of the present invention is to adjust the air outlet angle variable blade mounted on the air outlet of an air conditioner according to the sound pressure level of music. The point is to provide an air-conditioning blowout air fluctuation device that makes a local small space a comfortable environment by changing the direction at random.

(Means for Solving the Problems) In order to achieve the above-mentioned object, an air-conditioning blown-air fluctuation device according to the present invention includes an air-blowing angle variable vane rotatably mounted at a blow-out port of an air conditioner, and A rotary drive for variable wings,
The music playing device and the time integration of the sound pressure of the music played by the playing device are measured, the average sound pressure level per unit time is calculated, and in comparison with the preset maximum sound pressure level The operation control unit is configured to issue a command to the rotary drive device so as to classify the variable wing into an area and rotate the variable blade by an angle corresponding to the classified area.

(Operation) Since the present invention is configured as described above, music is played by a music playing device such as a CD player and a tape recorder, and the time integral of the sound pressure of this music is measured by the operation control unit to obtain a unit. Calculate the sound pressure level per hour,
This value is compared with a manually set maximum sound pressure level to be classified into a plurality of stages of regions, a command is issued to the rotary drive device of the variable blade, and the angle corresponding to the regions classified as described above is used. The variable blade is rotated, the rotation angle of the variable blade is randomly changed in response to the sound pressure level of music, and the blowing directions of warm air and cold air are randomly changed.

(Examples) The present invention will be described below with reference to illustrated examples.

(1) is an air conditioner, (2) is a vertically extending two-stage air outlet provided in the air conditioner body, and each air outlet (2) has a plurality of variable air outlet angle vanes (3) Are lined up.

Each of the variable vanes (3) has an outlet near the one end through the rotary shaft (4).
It is rotatably supported by the frame of (2) and blows out over the central part.
A horizontal axis (5) that moves in the longitudinal direction of (2) is arranged, and at the intersection of the horizontal axis (5) and each variable blade (3), the variable blade
The pin projecting from the horizontal shaft (5) slidably engages with the slot bored in (3), and the variable blade moves as the horizontal shaft (5) moves back and forth.
The (3) is configured to rotate about the rotary shaft (4) so that the blowing direction of the hot and cold air can be changed.

(6) is a step motor, which is a link pivotally supported by a pin (8) at an eccentric position of a disk (7) fixed to its drive shaft.
A link (10) is pivotally attached to the tip of (9), and the link (10) is further pivotally attached to the end of the horizontal shaft (5), thus driving the step motor (6) to move the horizontal shaft. (5) is moved back and forth, and the left and right variable vanes (3) are configured to rotate about the rotation shaft (4) in opposite directions.

The step motor (6), disk (7), link (9)
(10) The horizontal axis (5) constitutes a rotary drive device for the variable vane (3).

The outlets (2) are arranged adjacent to each other, and the horizontal axis of each outlet (2)
The opposite ends of (5) are respectively connected to both ends of a link (12) attached to a rotary shaft (11) arranged in the middle of both outlets (2).
It is pivoted through 3).

In the figure, (14) is a music player such as a CD player or tape recorder, (15) is an amplifier, and (16) is a speaker.

(17) is a step motor that converts the music played by the CD player, tape recorder, etc. into a sound pressure level.
The operation control unit sends a control signal to (6).

That is, the sound pressure f of the music is measured by the operation control section (17), and the time integration of the sound pressure f is measured. Is measured to calculate the average sound pressure level f _t per sample time t ₁ .

Then, the maximum sound pressure level fmax manually selected in advance is set in the operation control section (17), and the maximum sound pressure level is compared with the average sound pressure level f _t of the sample time t _1. The same sound pressure level f _t is classified into a plurality of stages of regions. In the illustrated embodiment, the variable blades are classified into the first stage to the sixth stage according to the sound pressure level f _t , and the upper and lower two stages of variable blades are classified according to each stage.
The rotation angle of (3) is controlled.

Next, the relationship between each of the stages and the rotation angles of the upper and lower variable vanes (3) will be described.

Thus, the sampling time t ₁ of the sound pressure level and the sampling interval t ₂ are also set in advance in the operation control unit.
It is entered in (17).
