Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to an air outlet device for an air conditioner that directs air blown out from the air conditioner in a predetermined direction.

(Prior Art) Generally, air that has been adjusted to a predetermined temperature by an air conditioner is blown into a vehicle interior from a blow-off grill through a blow duct.

As disclosed in Japanese Utility Model Application Publication No. 50-117536, a blow-off grill is usually provided with a plurality of movable blades arranged in parallel, and the blades are moved up and down or left and right to blow the air. The blowing direction can be changed up and down or left and right.

Furthermore, so-called one-box cars and the like are known in which an air outlet device is attached to the ceiling of the vehicle interior. In such an air outlet device, if you want to blow air toward the front seats located nearby, the air outlet grille should be turned downward, and if you want to blow air towards the rear seats, you can adjust the air outlet grille to point it horizontally. I'm starting to do that.

(Problem that the invention aims to solve) However, since the speed of the air blown out from the outlet grille is constant no matter which direction it is blown out, in the front seats, even if the air velocity is appropriate, the outlet grille will remain unchanged. If the air is directed toward the rear seats far away, the air may not reach the passengers in the rear seats, and the air may not be blown sufficiently, or the air may not be blown comfortably.

Therefore, the object of this invention is to provide an air outlet device for an air conditioner that can receive sufficient and comfortable air from any position.

(Means for Solving the Problems) An air conditioner outlet device according to this invention is an air conditioner outlet device equipped with an outlet grille for adjusting the blowing direction of air at the air outlet. A damper arranged to substantially change the cross-sectional area of the ventilation passage, and an interlocking means for operating the damper in conjunction with the displacement of the outlet grille, the damper being arranged so as to direct the outlet direction to the vicinity of the outlet device. When the outlet grille is displaced, the damper is actuated to increase the cross-sectional area of the passage, and when the outlet grille is displaced so that air is directed far away, the damper is actuated to substantially reduce the cross-sectional area of the passageway. It is characterized in that it is operated to do.

(Function) Therefore, when the blowout grille is displaced so as to blow air far away, the cross-sectional area of the blowing passage is substantially narrowed by the damper and the air blowing speed is increased.
It is possible to obtain sufficient wind speed so that the blown air reaches even at a position far from the outlet.

(Example) An example of this invention will be described in detail below with reference to the accompanying drawings.

As shown in FIG. 3, the one-box car 1 has a first row of driver seats 2 and passenger seats 3 in front, and a second row of front seats 4 and a third row of rear seats 5 behind it.
columns are arranged.

Air at a predetermined temperature and air volume is blown to the front driver's seat 2 and front passenger seat 3 from a driver's seat cooling unit 7 provided below the instrument panel 6.

On the other hand, in addition to the cooling unit 7 for the driver's seat, a cooling unit 8 as an air conditioner for the vehicle is provided on the ceiling of the vehicle interior, and cool air is blown toward the rear seats.

At the rear of the cooling unit 8, there is an outlet device 11 that blows cold air toward the front seats 4 and the rear seats 5.
is provided. As shown in FIGS. 1 and 2, this air outlet device 11 is provided with an air outlet grille 12 that is slidable so as to adjust the air blowing direction. It is configured so that it can be blown out.

The outlet grill 12 has upper and lower surfaces 13a and 13b.
is formed in a circular arc shape, and is slidably provided on circular arc surfaces 14a and 14b formed inside the air outlet device 11. The blowout grille 12 has a plurality of blades 15 arranged substantially parallel to each other for regulating and guiding the flow of blowing air, and a knob 16 is protruded from the front of the blowout grille 12. This knob 16 is used when changing the blowing direction. Hold the blowout grill 12
It is designed to slide.

A damper 17 is arranged behind the outlet device 11 and rotates to stand up in conjunction with vertical sliding of the outlet grille 12.

The damper 17 has a rotation shaft 18 on the upstream side in the ventilation passage.
It is mounted so that it can rotate freely around the center. A coil spring 19 is interposed on the rotation shaft 18, and the damper 17 is always moved in its rising direction (direction of arrow A).
is energized by Further, an arm 20 is integrally attached to the damper 17 on its rotation shaft side, and by rotating this arm 20, the damper rotates against or in accordance with the biasing force of the coil spring 19. It's starting to move.

An interlocking means 21 that interlocks in response to the displacement of the blow-off grille 12 is connected to the tip of the arm 20 . This interlocking means 21 has an arm 20 at one end.
The damper 17 has a wire 24 whose other end is attached to the lower end 27 of the outlet grille, and a pulley 25 that guides the direction of the wire 24. I'm starting to convey it.

With the above configuration, when the outlet grille 12 is to be directed toward the front seat 4, for example, the user holds the knob 16 of the outlet grille and directs the blade 15 downward, as shown in FIG. In this case, the damper is pulled to lie down against the biasing force of the coil spring 19 of the rotation shaft 18. Therefore, the air from the blower case 9 is blown out from the outlet at the same speed without being affected by anything.

On the other hand, when blowing cold air far away, for example to the rear seat 5 side, the blow-off grille 12 is oriented horizontally as shown in FIG. In this case, the wire 24 is loosened and the coil spring 1 of the rotation shaft is
The damper 17 is rotated to the upright position in accordance with the urging force of the damper 9. Then, the ventilation passage 26 of the air passing through the ventilation case 9 has a cross-sectional area of the damper 1.
7, the wind speed of the air passing through this increases and is blown out from the blow-off grille 12 at a high wind speed. Therefore, sufficient air can be blown even to distant places.

Further, in this embodiment, the damper 17 is configured to rise depending on the angle at which the blow-off grille 12 is displaced, so that its strength can be changed depending on the direction of air blowing. For example, if you set the initially set airflow strength to medium, you can receive air of the same strength from any position, so you can obtain a comfortable air conditioning feeling. Can be done.

Note that the damper 17 is
The interlocking means 21 that interlocks the above-mentioned wire 24
The damper can be rotated by a motor that detects the position of the outlet grille and drives it accordingly, or a gear that rotates according to the amount of rotation of the outlet grille and is interlocked with a gear that meshes with the rotational amount of the outlet grille. A similar effect can be obtained by moving the

Further, the direction of the grille is not limited to the vertical direction, but may be such that the grille slides from side to side, and the damper is configured to move in conjunction with this.

Furthermore, the damper is not limited to a rotating type as in this embodiment, but may be a sliding type damper or any other type capable of changing the passage cross-sectional area.

(Effect of the invention) According to this invention, when the blowout grille is displaced so as to blow air far away, the damper is operated by the interlocking means to narrow the cross-sectional area of the passage, thereby reducing the air blowing speed. Because it can be made larger, you can receive sufficient and comfortable ventilation even when you are far away.
