Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has a louver formed of a plurality of fins parallel to the upper and lower peripheral walls at a front portion between the upper and lower peripheral walls, and the upper and lower peripheral walls behind the louvers. A barrel in which a plurality of fins are arranged so that the left and right wind directions can be adjusted in the orthogonal direction therebetween, and a barrel for an automobile register pivotally supported on both side surfaces of an outlet of a blow case so that the upper and lower wind directions can be adjusted. is there. 2. Description of the Related Art A register of this kind is disclosed in Japanese Utility Model Laid-Open No. 1-140.
It is well-known from Japanese Patent No. 447, etc., and is attached to an instrument panel or the like, so that the wind direction can be adjusted vertically by rotating the barrel, and the wind direction on the left and right can be adjusted by rotating the fin behind. I have. [0003] However, when the barrel is turned to adjust the wind direction, for example, downward, the lower peripheral wall of the barrel turned inward of the blower case opens the outlet. As a result, the area is reduced, and the air volume is reduced. Further, the air flows into the gap between the lower surface of the outlet and the lower surface along the lower peripheral wall and leaks. SUMMARY OF THE INVENTION In view of the foregoing, it is an object of the present invention to provide a vehicle register of the type described at the beginning, which can suppress a decrease in air volume or the generation of abnormal noise when adjusting the vertical wind direction. . In order to achieve this object, according to the present invention, according to the present invention, a front louver formed of a plurality of fins along a wind direction is provided. A fin and a plurality of fins arranged in a manner that can be adjusted and operated by interlocking the left and right wind directions behind the louver in the orthogonal direction are provided on the peripheral walls on both sides of the barrel. In an automobile register pivotally supported on both sides, outer surfaces of upper and lower peripheral walls of the barrel are formed into a curved surface corresponding to a radius of rotation centered on the pivotal position of both sides of the outlet opening, and this curved surface is formed. The upper and lower surfaces of the opening for the outlet are also formed as curved surfaces in close proximity to the lower peripheral wall, and the width in the blowing direction is set to be larger than the upper peripheral wall so as to increase the downward maximum wind direction adjustment angle. On the lower peripheral wall. A fin that forms an opening that blows toward the louver along the blowing direction at a large wind direction adjustment angle is formed, and the position of this fin deviates from the lower surface of the outlet opening in the blowing direction at an upward maximum wind direction adjustment angle. It is characterized in that it is not set. When the barrel is adjusted to the maximum angle upward, the fin does not come off from the lower surface of the opening for the outlet, and when the fin is adjusted to the maximum angle downward more than the maximum maximum angle. Thus, the opening of the lower peripheral wall is blown toward the louver along the blowing direction, so that a dead end is avoided. FIG. 1 and FIG. 2 show a register according to an embodiment of the present invention. As shown in FIG. 2, the register is mounted, for example, at an outlet of a ventilation duct 9 of an instrument panel. It comprises a blower case 1 and a barrel 10. The blower case 1 has an opening 1b for the outlet.
A bezel 1a is mounted on the rear side of the valve 8. A valve 8 that turns on and off the air supply by rotating a knob 8a from a blowing direction to a damping position in the orthogonal direction by operating a knob 8b is accommodated behind the bezel 1a. The barrel 10 has both peripheral walls 13 formed with pins 13a rotatably inserted into pin holes 7 formed on both sides of the opening 1b, and a radius of rotation centered on the pin holes 7. And upper and lower peripheral walls 11 and 12 each having a curved surface shape. A louver 15 formed of a plurality of fins 15a parallel to the peripheral walls 11 and 12 and along the wind direction is provided at a front portion of the peripheral walls 11 and 12, that is, on the outlet side. Behind the fins 15a, a plurality of fins 16 are arranged laterally in a direction perpendicular to the fins 15a to adjust the left and right wind directions, and are vertically supported by upper and lower peripheral walls 11, 12 by pins 16a. All the fins 16 are rotatably connected to a horizontal bar 16c operated by a knob 16b, and are rotated left and right in conjunction with each other. The lower peripheral wall 12 is set to have a larger width in the blowing direction than the upper peripheral wall 11 so as to increase the downward rotation angle. In other words, the maximum wind direction adjustment angle in which the louver 15 is downward with respect to the normal position along the wind direction is 42 °,
The maximum upward wind direction adjustment angle is set to 30 °.
Upper and lower surfaces 1c, 1 of the outlet 1b of the blower case 1
d is also formed on an adjacent radial curved surface. Although the register itself having such a structure is well-known, according to the present invention, the louver 15 is attached to the lower peripheral wall 12 at a maximum downward angle of 42 ° from the normal position along the blowing direction. The fins 18 which form the front and rear openings 18a, 18b for blowing toward the louver 15 when turning inward are formed along the blowing direction. The fins are set so as not to move outward from the lower surface 1d of the outlet opening 1b at a maximum upward wind direction angle of 30 °, that is, in the air blowing direction. The operation of the register thus configured will be described with reference to FIG. When the barrel 10 is rotated downward from the normal state shown in FIG. 1, the louver 15 is adjusted downward. The opening 1b for the outlet gradually lowers the peripheral wall 1.
If it is to be narrowed by 2, the openings 18a, 18b gradually increase the area facing the blowing direction to avoid a dead end. When the angle is adjusted to the maximum downward angle shown in FIG. 3A, the fins 15a extend in the air blowing direction, the air that has entered the lower peripheral wall 12 is blown to the front louver 15, and the narrow space between the upper and lower surfaces 1c, 1d is narrow. A gap is formed to suppress air leakage. Air that can end up and flow into the slit and generate abnormal noise is significantly reduced. Since the upper peripheral wall 11 has no opening, it does not disturb the downward wind direction. Conversely, when the barrel 10 is turned upward, the wind direction is adjusted upward. Even when the fin 18 is adjusted to the maximum angle upward as shown in FIG. 3B, the fin 18 does not come off from the lower surface 1d of the opening 1b for the outlet and faces the air blowing direction, and the openings 18a and 18b face the downward air. And does not disturb the wind direction. At that time, the upper peripheral wall 11
Since the maximum rotation angle is small with respect to the downward wind direction adjustment, the blowing loss is small. The present invention can be applied to a case where the blower case is directly formed at the outlet of a blower duct formed on a panel of an automobile body. According to the present invention, the swing angle of the barrel,
In other words, even when the downward wind direction adjustment angle is large, the fins are formed in the opening of the lower peripheral wall, thereby eliminating the blast loss that may be large, and facing upwards at the lower surface of the outlet at the time of upward swing. The wind direction is not disturbed.
