[Structure] A plurality of fixed fins 5 whose directing directions sequentially change from upper to lower are provided at the opening end of the outlet to support a barrel 7 capable of rotating in the vertical direction in the outlet, and at the same time, the barrel is supported. A vertical fin 8 that can be rotated in the left-right direction is provided inside 7.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an outlet structure of an air conditioner installed in a vehicle.

[0002]

[Prior Art]

 The instrument panel of a vehicle is generally provided with an outlet for an air conditioner. It is desirable that the airflow from this outlet can be adjusted both vertically and horizontally.

As an outlet structure for adjusting the wind direction in the up and down direction and the left and right direction, generally, in the related art, horizontal fins that are linked to each other and are pivotally operated in the up and down direction are provided in parallel with each other in the outlet port. It has a structure in which vertical fins that are connected to each other and are rotated in the left-right direction are provided in parallel with each other.

[0004]

[Problems to be solved by the device]

 By the way, in the above-mentioned conventional structure, the vertical blowing direction is restricted by the lateral fins that have been rotated to be upward, downward, or an intermediate direction between them. However, in a vehicle with a large passenger compartment and a high passenger compartment, such as a one-box van-type vehicle, in order to quickly spread the air conditioning to the entire passenger compartment, it is necessary to move the air conditioner up and down at the start of air conditioning. It is desirable to blow air simultaneously over a wide range including the middle.

Therefore, the present invention has an object to provide an outlet structure capable of adjusting the wind direction to the left and right and up and down and capable of simultaneously blowing air over the entire upper and lower ranges.

[0006]

[Means for Solving the Problems]

 The present invention provides a plurality of fixed lateral fins at the opening end of the outlet of a vehicle air-conditioning system, the direction of which changes from upward to downward, and is horizontally supported inside the outlet. In addition to providing a barrel that pivots in the vertical direction, a plurality of vertical fins that pivot in the left-right direction are provided in the barrel, and the barrel has operating means for pivoting the barrel and the vertical fins. To do.

[0007]

[Action]

 By rotating the barrel and the vertical fins, the wind direction can be adjusted vertically and horizontally. Also, if the barrel is set in a substantially horizontal direction, the blast will be guided by the horizontal fins and spread over the entire area above and below and sent into the passenger compartment.

【Example】

 As shown in FIG. 1, an instrument panel 1 of a van-type vehicle is provided with an outlet 3 communicating with a duct 2 of an air conditioner, and an opening end thereof has a plurality of horizontal fins arranged vertically. An outlet frame 4 integrally formed with 5 is attached. The outlet 3 is provided with a casing 6 whose front and rear are open, and a barrel 7 is horizontally supported in the casing 6. In the barrel 7, a plurality of vertical fins 8 are arranged side by side in the left-right direction.

As shown in FIG. 2 (A), the outlet frame 4 (only one of the left and right sides is shown in the figure) has a shape in which a central portion is projected, and a fixed lateral portion formed in the central portion. The fin 5 has its pointing direction sequentially changed from upward to downward. A casing 6 is attached to the rear side of the outlet frame 4.

As shown in FIG. 2B, a plurality of vertical fins 8 (only one of which is shown in the drawing) is rotatably supported at the front edge of the barrel 7 by a vertical axis 8a. .. The casing 6 and the barrel 7 are in contact with each other, and a pair of left and right is provided (the figure shows only one of them, and the structure on one side will be described below).

A shaft portion 7a is provided on the side wall of the barrel 7, and the shaft portion 7a is rotatably supported in a round hole 4a formed in the side surface of the outlet frame 4. As a result, the barrel 7 is horizontally supported so as to be vertically rotatable. The shaft portion 7a is provided with a rectangular protrusion 7b on its side surface. A bar 9 penetrating the protruding portion 7b, the shaft portion 7a and the side wall of the barrel 7 is arranged so as to horizontally traverse the inside of the barrel 7. Holes 9a are formed in the bar 9 at predetermined intervals, and a shaft 9b is inserted into each hole 9a so as to be relatively rotatable with respect to the bar 8. The rim side is connected to the bar 9.

A square hole 10 a is formed in the center of the circular knob 10. The knob 10 is provided in a recess 4b formed on the side surface of the outlet frame 4 shown in FIG. 2 (A), and is supported with the square protrusion 7b of the barrel 7 fitted in the square hole 10a. To be done. A lateral groove 10b is formed on the outer surface of the knob 10. Then, the handle 11 is arranged in the lateral groove 10b. The handle 11 is connected to the end of the knob 10 with a pin 12a at the base end thereof, extends through the rectangular protrusion 7b at a position near the base end of the central portion, and further extends through the square hole 10a. It is connected to one end of the bar 9 with a pin 12b. The bar 9, the knob 10 and the handle 11 constitute an operating means for rotating the barrel 7 and the vertical fin 8.

In the above outlet structure, when the knob 10 is rotated, the rotational force is transmitted to the barrel 7 via the rectangular protrusion 7b of the barrel 7, and the barrel 7 rotates in the vertical direction. When the operating end of the handle 11 is operated in the left-right direction, the bar 9 moves in the left-right direction, whereby each vertical fin 8 changes its direction in the left-right direction.

Therefore, the vertical adjustment of the blown air is performed by operating the knob 10 and rotating the barrel 7 in the vertical direction. Further, the adjustment of the blowing air in the left-right direction is performed by operating the handle 11 to rotate each vertical fin 8 in the left-right direction. In addition, when air is to be blown simultaneously over the entire area above and below, the barrel 7 is set in the approximately middle direction. As a result, the wind that has left the barrel 7 and has spread is guided by the horizontal fins 5 that are directed from the upper side to the lower side, and is widely blown in the vertical direction.

[0015]

EFFECTS OF THE INVENTION According to the outlet structure of the present invention, it is possible to adjust the airflow to the passenger compartment in the desired directions of up, down, left and right, and also to simultaneously blow the air over the entire area in the up and down direction. Further, since the lateral fin at the opening end of the outlet is a fixed fin, it is possible to form a continuous fin without interruption in the outlet frame, and the appearance of the outlet can be improved.
