Description

[Detailed Description of the Invention] The present invention relates to a cooler blowout structure for an automobile air conditioner, in which each fin is connected to a variable direction mechanism that operates so that the cold air blown out from the outlet is converged or diffused. When solar radiation is concentrated on a part of the body, that part can be rapidly cooled, or the interior of the vehicle can be uniformly cooled by blowing cold air to envelop the entire interior of the vehicle. The purpose of this invention is to obtain a cooler outlet structure that allows for

In the conventional air conditioner for automobiles, the cooler outlet structure has a plurality of fins that are turned parallel to each other by a link mechanism, and the direction of the fins is changed downward or to the left or right. Furthermore, it is not possible to diffuse the cold air to envelop the entire interior of the vehicle.

This invention has the configuration described in the claims for utility model registration, and provides rapid cooling by sending out strong cold air in spots during rapid cooling down or when solar radiation is partially hitting the occupant's body. In addition, the present invention provides a cooler outlet structure capable of uniformly cooling the vehicle interior by enveloping the entire interior of the vehicle when a weak cold air is sufficient, such as during general driving or at night.

The configuration of the present invention will be explained below based on the embodiments shown in the drawings.

What is shown in FIGS. 1 to 4 is an embodiment of the present invention, and there are a plurality of grill plates (five in this embodiment) in the grill case 1.
fins 2a, 2b, 2C.

2d and 2e are arranged, and the central fin 2C is fixed to both inner walls 3a and 3b of the grill case 1.

One end of each of the upper fins 2a, 2b and the lower fins 2d, 2e of the fin 2C is rotatably supported on the inner wall 3a of the grill case 1 by a rotating shaft 4.

The fins 2a, 2b, 2d, 2e (7)
A connecting shaft 5 whose tip protrudes outward from the grill case 1 is fixed to one end of each of the connecting shafts, and a fin fixing lever 6a, 6b of the same shape is provided at the tip of each connecting shaft 5.

The upper ends of 6d and 6e are fixed.

Further, a pin shaft 7 for rotating the fin fixing levers 6a to 6e is provided at the lower end of the fin fixing levers 6a to 6e.
a, 7b, 7d, and 7e are the fin fixing levers 6a.

It protrudes substantially perpendicularly to 6b, 6d, and 6e.

On the other hand, on the outside of the side wall 3b of the grill case 1, a movable link 9 having a hole 8 corresponding to each of the pin shafts 7a to 7e and into which the pin shafts 7a to 7e can be fitted is located at a pivot portion 11 located approximately at the center of the movable link 9.
Each hole 8 has a corresponding pin shaft 7a, 7b, 7d, 7e.
are fitted.

With the above configuration, when the fin 2b is rotated upward or downward, the movable link 9 is rotated clockwise or counterclockwise by the operation of the connecting shaft 5, the fin fixing levers 6a to 6e, and the pin shafts 7a to 7e. moved,
At this time, the part of the movable link 9 on the -L side from the pivot part 11 and the part below the pivot part 11 are tilted in opposite directions with respect to the pivot part. The set of fin fixing levers 6a and 6b and the set of fin fixing levers 6d and 6e that are engaged are rotated in opposite directions.

Each of the holes 8 has a shape that does not hinder the rotational movement of the movable link at least when the fin 2b performs the aforementioned rotational movement.

In the illustrated embodiment, an operating knob 10 for rotating the fins is attached to the front edge of the fin 2b.

2e may be attached.

Further, the operation knob 10 is not essential, and the fins may be operated directly with fingers, or the fins may be rotated by other means.

Figure 2 shows the operation of the cooler outlet structure having the above configuration.
To explain in detail based on FIGS. 3 and 4, the operation knob 10
When the fin 2b is maintained horizontally, each fin fixing lever 6a, 6b.

6d, 6e and the center line of the movable link 9 are located on a vertical straight line, and each fin 2a, 2b, 2C.

2d and 2e are arranged horizontally in parallel.

This state is shown in FIG. 2, and the cold air sent out from the outlet becomes a parallel flow.

In each of FIGS. 2, 3, and 4, the left side of the drawing is the interior of the vehicle.

Further, when the fin 2b is rotated downward, that is, in the direction of the central fin 2C using the operating knob 10, the pin shaft 7b is rotated counterclockwise via the connecting shaft 5 and the fin fixing lever 6b.

Since the pin shaft 7b is fitted into the hole 8 of the movable link 9, when the pin shaft 7b rotates as described above, the movable link 9 cannot rotate clockwise about the pivot portion 11 as a fulcrum. .

Due to the rotation of the movable link 9, one of the pin shafts 7a is prevented from rotating counterclockwise through the hole 8, and the lower pin shafts 7d and 7e are rotated downward from the pivot portion 11 of the movable link 9. Since the portion tilts in the opposite direction to the pivot portion 11 relative to the portion above the pivot portion 11, it cannot be rotated clockwise.

By the above operation, the fin 2a is rotated downward, that is, in the direction of the central fin 2C, and the lower fins 2d and 2e are rotated upward.

This state is shown in FIG. 3, and the cold air sent out from the outlet becomes a converging flow toward the center.

Further, when the operation knob 10 is rotated upward, the fin fixing levers 6a, 6b, and 6d are activated.

6e, the pin shafts 7a, 7b, 7d, 7e and the movable non-stop 9 rotate in a manner opposite to the operation shown in FIG. move.

This state is shown in FIG. 4, and the cold air sent out from the outlet becomes a diffused flow that flows throughout the vehicle interior.

In this embodiment, the fins are arranged horizontally in parallel within the grill case, but they can also be arranged vertically in parallel in the longitudinal direction and have the same structure as described above.

Further, it goes without saying that the above structure can be used not only as a cooling device but also as a heating device.

As described above, in the present invention, a plurality of fins are arranged inside the grill case, and among the fins, the central fin is horizontally fixed to the grill case, while each of the upper and lower fins has one end rotatably pivoted. A connecting shaft protruding outward from the grill case is fixed in a straight line to the other end of the grill case, and the upper end of the fin fixing lever is approximately perpendicular to the fin at the tip of each of the connecting shafts. A pin shaft is provided at the lower end of each of the fin fixing levers at a right angle to the fin fixing lever, and a pin shaft is provided on the outer side wall of the grill case to correspond to each of the pin axes. A movable link having a hole into which the pin can be fitted is rotatably supported approximately at the center thereof, and each hole has a shape that does not hinder the rotational movement of the movable link. By rotating the fins upward or downward, the entire fin can be tilted so that the cold air sent out from the outlet becomes a convergent flow or a diverging flow, and solar radiation is concentrated on a part of the body. If there is a flow of cold air, the fins can be operated so that the flow of cold air becomes a convergent flow to quickly cool the area in a sporadic manner. Alternatively, if weak cold air is sufficient during general driving or night driving, the flow of cold air can be By manipulating the fins so that the air becomes a diffused flow, the entire interior of the vehicle can be uniformly cooled by enveloping the entire interior of the vehicle with cool air.
