Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an air outlet grill device for, for example, a ceiling-suspended air conditioner.

[Technical background of the invention]

BACKGROUND ART Conventionally, a ceiling-suspended air conditioner has a main body mounted parallel to a ceiling surface, an air inlet on the lower surface of the main body, and an air outlet on the front surface. The air outlet is equipped with an air outlet grill that changes the air blowing direction, allowing the user to switch between cooling and heating, as well as setting the air blowing direction to suit the user's preference. .

That is, a plurality of air outlet grilles are rotatably supported at the air outlet, and these air outlet grilles are interlocked by an interlocking member, and when any one of the air outlet grilles is rotated, each air outlet is connected via the interlocking member. The grille rotates in the same direction so that the direction of air blowout can be varied.

However, since the blowout grilles are only rotated vertically or horizontally, there is little choice in the blowout direction, and the mutual spacing between the blowout grilles is constant, making it impossible to change the blowout air speed. There is an inconvenience.

[Purpose of the invention]

This invention was made in view of the above-mentioned circumstances, and its purpose is to be able to arbitrarily select and set combinations of inclination angles of a plurality of blowout grilles, and to have a wide selection range of blowout directions. An object of the present invention is to provide a blowout grill device for an air conditioner that can change the blowout wind speed.

[Summary of the idea]

In order to achieve the above-mentioned object, the present invention provides a plurality of air outlet grilles provided at an air outlet and rotatably supported around a substantially intermediate portion in the air blowing direction as a fulcrum, and a projecting portion at one end of these air outlet grilles. a connecting shaft installed between the plurality of outlet grills, a connecting hole provided at one end to connect with the connecting shaft of at least one outlet grill, and a connecting shaft of the remaining at least one outlet grill at the other end; and a connecting member that connects the plurality of outlet grilles together and independently rotatably connects the plurality of outlet grilles, and the combination of the inclination angles of the outlet grilles. The reason is that we have made it possible to select and select.

[Embodiments of the invention]

Hereinafter, one embodiment of the present invention will be described based on the drawings.

FIG. 1 shows an exploded view of a ceiling-mounted air conditioner, where 1 is the main body. Inside the main body 1, an indoor heat exchanger 2, a blower 3, and an electrical parts box 4 are housed. A drain plate 5 is provided on the bottom surface of the main body 1.
A decorative board 6 is provided through the decorative board 6, and a suction port 7 is provided in a part of the decorative board 6. Further, side plates 8, 8 are attached to the sides of the main body 1, and an air outlet 9 facing the indoor heat exchanger 2 is provided on the front surface of the main body 1. The outlet 9 is provided with an outlet grill device 10 that changes the direction of the air being blown out. That is,
End plates 11 are provided at both longitudinal ends of the outlet 9,
11 is fixed thereto, and both ends of a plurality of outlet grilles 12, 13 are rotatably supported on these end plates 11, 11 via rotating shafts 12a, 13a. These blow-off grilles 12 and 13 are configured to rotate in the vertical direction about rotating shafts 12a and 13a, and to be set to an arbitrary inclination angle by an interlocking mechanism 14, which will be described later.

That is, FIG. 2 shows the interlocking mechanism 14, and 12b and 13b are the air outlet grilles 12 and 1.
This is a connecting shaft that protrudes from the rear end side of one end surface of 3. Further, 15 is a connecting plate, and this connecting plate 15
A connecting hole 16 into which the connecting shaft 12b fits is bored at one end. Further, a connecting elongated hole 17 is bored in the other end of the connecting plate 15, and this connecting elongated hole 17 is fitted into the connecting shaft 13b.
The distance a between the connecting hole 16 of the connecting plate 15 and the upper end of the connecting elongated hole 17 is equal to
The distance b between the rotating shafts 12a and 13a is substantially the same as the distance b between the rotating shafts 12a and 13a, so that when the connecting shaft 13b is located at the upper end of the connecting elongated hole 17, the outlet grilles 12 and 13 are kept parallel.

Next, the operation of the blowout grill device 10 configured as described above will be explained.

First, in FIG. 2, the outlet grilles 12 and 13 are in a horizontal state, and the connecting shaft 13b is located at the upper end of the connecting elongated hole 17. When the outlet grille 13 is tilted downward from this state as shown in FIG. 3, the connecting plate 15 is pushed upward by the connecting shaft 13b. Therefore, the outlet grille 12 is also inclined in the same direction via the connecting plate 15, and the outlet grille 1
2 and 13 are inclined downward. Next, as shown in FIG. 4, when only the lower outlet grille 13 is tilted upward, the connecting shaft 13b moves within the connecting slot 17 of the connecting plate 15, so no downward force is applied to the connecting plate 15. do not have. Therefore, the inclination angle of only the lower outlet grille 13 can be varied while the upper outlet grille 12 remains stationary. Further, when the lower blow-off grille 13 is further rotated upward, the connecting shaft 13b comes into contact with the lower end of the connecting elongated hole 17, as shown in FIG. Therefore, the connecting plate 15 is pushed down, and the upper air outlet grille 12 is tilted upward via the connecting shaft 12b. Furthermore, as shown in FIG.
3 upward, the upper outlet grille 12 is rotated upward via the connecting plate 15 and becomes horizontal, and when the lower outlet grille 13 is rotated downward again, the connecting shaft 13b is adjusted to the connecting length. It moves within the hole 17 and becomes horizontal, returning to its original state (FIG. 2).

Therefore, the downward blowing angle can be set arbitrarily in the states shown in FIGS. 2 and 3. Furthermore, in the states shown in FIGS. 4 and 5, the area of the blowout opening can be reduced, so that the speed of the blowout air can be increased and the blowout air can reach a far distance. Furthermore, in the state shown in FIG. 6, the wind speed can be increased upward.

In the above-mentioned embodiment, a case has been described in which the blow-off grille 13 is rotated manually, but it may be rotated electrically as shown in FIG.
That is, 18 is an electric motor, and this rotating shaft 1
A rotary plate 20 is attached to 9. An arm 21 is connected to a part of the rotary plate 20, and the tip of the arm 21 is connected to a connecting shaft 13b of the outlet grille 13. However, the electric motor 18
When the rotary plate 20 is rotated by the arm 21, the arm 21 can reciprocate in the vertical direction to rotate the outlet grille 13, and the outlet grilles 12 and 13 can be changed periodically and continuously. In addition, by stopping the electric motor 18, the outlet grill 1
2 and 13 can also be fixed at arbitrary positions.

Furthermore, the present invention is not limited to ceiling-mounted air conditioners, but can also be applied to outlet grill devices such as window-type and floor-standing air conditioners. Further, the number of blowout grilles is not limited to two, and may of course be set to various numbers.

〔Effect of the invention〕

As explained above, according to the present invention, it is possible to select and set a combination of the inclination angles of a plurality of outlet grilles, so a wide selection range of air blowing directions can be obtained, and the blowing wind speed can be changed to The effect is that the distance can be varied and comfortable air conditioning can be obtained.
