Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is provided with a louver formed by a plurality of fins in parallel with the upper and lower peripheral walls at the front part between the upper and lower peripheral walls, and between the upper and lower peripheral walls behind the louver, the left and right wind directions are orthogonal to each other. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle register in which a barrel in which a plurality of fins are arranged so that the fins can be adjusted is pivotally supported on both sides of an outlet of a blower case so that the vertical airflow direction can be adjusted.

[0002]

2. Description of the Related Art A register of this type is known as an actual Kaihei 1-140.
It is well known from Japanese Patent No. 447, etc., and by attaching it to an instrument panel or the like, the wind direction can be adjusted up and down by rotating the barrel, and the left and right wind directions can be adjusted by rotating the fins on the back. There is.

[0003]

However, when the barrel is rotated to adjust the wind direction, for example, downward, the lower peripheral wall of the barrel rotated inward of the blower case narrows the opening area of the outlet. Therefore, there is a problem that an abnormal noise is caused by reducing the air flow rate and further flowing into the gap with the lower surface of the outlet along the lower peripheral wall to leak.

In view of the above points, the present invention has an object to provide an automobile register of the kind mentioned at the beginning, which can suppress the reduction of the air volume or the generation of abnormal noise during the adjustment of the vertical wind direction. .

[0005]

In order to achieve this object, the present invention provides, according to claim 1, a front louver formed by a plurality of fins along the wind direction, and these fins. A barrel equipped with a plurality of fins arranged in a direction orthogonal to each other behind the louver so that the left and right wind directions can be adjusted and interlocked with each other. In the pivotally supported automobile register, one or both of the upper and lower peripheral walls of the barrel are formed with an opening for blowing air toward the louver when adjusting the vertical wind direction by rotating the barrel.

[0006]

[Function] When the barrel is rotated when adjusting the up and down wind direction,
The air blown to the upper or lower peripheral wall of the barrel rotated inward of the blowout port is blown to the louver through the opening. Therefore, the amount of air that becomes a dead end at the peripheral wall and tends to leak from the gap between the upper and lower surfaces of the outlet opening is also reduced.

[0007]

1 and 2 show a register according to an embodiment of the present invention. As shown in FIG. 2, the register is, for example, a blower case attached to the outlet of a blower duct 9 of an instrument panel. 1 and a barrel 10. The blower case 1 has an opening 1b for its outlet.
A bezel 1a is attached to the rear of the valve 8 and a valve 8 for turning on / off the blower is housed behind the bezel 1a by rotating the knob 8a from the blower direction to the damping position in the orthogonal direction via the crank 8b.

The barrel 10 corresponds to the peripheral walls 13 on both sides formed with pins 13a rotatably inserted into the pin holes 7 formed on both sides of the opening 1b and the radius of gyration about the pin holes 7. The upper and lower peripheral walls 11 and 12 having curved surfaces are provided. A louver 15 formed of a plurality of fins 15a parallel to the peripheral walls 11 and 12 along the wind direction is provided on the front portions of the peripheral walls 11 and 12, that is, on the outlet side. Behind it, a plurality of fins 16 arranged laterally in a direction orthogonal to the fins 15a to adjust the left and right wind directions are provided, and the top and bottom are pivotally supported by the upper and lower peripheral walls 11, 12 by pins 16a. All of the fins 16 are rotatably connected to a horizontal bar 16c operated by a knob 16b, and are interlocked to be pivoted left and right.

The lower peripheral wall 12 is set to have a width in the blowing direction larger than that of the upper peripheral wall 11 so as to increase the downward rotation angle. In other words, the downward maximum wind direction adjustment angle of the louver 15 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, 1c of the opening 1b for the outlet of the blower case 1
d is also formed on the adjacent curved surface.

Although the register itself having such a structure is well known, according to the present invention, the louver 15 is provided on the lower peripheral wall 12 at the time of adjusting the wind direction at a maximum angle of 42 ° downward from the normal position along the blast direction. Fins 18 that form openings 18a and 18b in the front and rear that blow air toward the louver 15 when rotated inward are formed along the air blowing direction. Further, the fins are set so as not to come off from the lower surface 1d of the outlet opening 1b, that is, in the blowing direction at an upward maximum wind direction angle of 30 °.

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 is gradually formed on the lower peripheral wall 1
If it is attempted to narrow the width by 2, the openings 18a and 18b gradually increase the area facing the air blowing direction to avoid a dead end. When adjusted to the maximum downward angle shown in FIG. 3A, the fins 15a are along the blowing direction, the air that has entered the lower peripheral wall 12 is blown to the front louver 15, and there is a small gap between the upper and lower surfaces 1c and 1d. A gap is formed to prevent air leakage. The air that can stop and flow into the slit and generate abnormal noise is greatly reduced. Since the upper peripheral wall 11 does not have an opening, the downward wind direction is not disturbed.

On the contrary, when the barrel 10 is rotated upward, the wind direction is adjusted upward. Even when the fins 18 are adjusted upward to the maximum angle shown in FIG. 3B, the fins 18 do not come off from the lower surface 1d of the blowout opening 1b, but face in the air blowing direction, and the openings 18a and 18b face downward air. Does not occur and does not disturb the wind direction. At that time, the upper peripheral wall 11
Since the maximum rotation angle of is small with respect to the downward adjustment of the wind direction, the air loss can be small.

FIG. 4 shows another embodiment of the present invention. Pins 21a that engage with pin holes 22 on both side peripheral walls of the barrel 20 are projectingly provided on both sides of the outlet of the blower case 21, and the barrel 20 is pivotally supported so that the wind direction can be adjusted up and down. The outer surfaces of the upper and lower peripheral walls 26, 27 are formed in a radial shape centered on the pin hole 22, and the knob 2 is passed through the louver 23.
A plurality of fins 29 whose left and right wind directions are adjusted by the operation of 8 are stored. According to the present invention, openings 26a and 27a are formed inwardly of the upper and lower peripheral walls 26 and 27, respectively. As a result, when the airflow direction is adjusted upward as shown in FIG. 5, the opening 26a blows air toward the louver 23, and the opening 27a faces the lower surface 21b of the air outlet so that air leakage hardly occurs. On the contrary, when adjusted downward, the opening 27a blows air toward the louver 23.

The present invention can also be applied to the case where the blower case is directly formed on the outlet of the blower duct formed on the panel of the automobile body.

[0015]

According to the first aspect of the present invention, when the barrel is rotated to adjust the wind direction in the vertical direction, the upper and lower peripheral walls of the barrel are provided with the openings, thereby reducing the area of the outlet. Therefore, it is possible to suppress the generation of abnormal noise due to the reduction of the air volume and the air leakage between the peripheral wall and the upper and lower surfaces of the air outlet.

According to the second aspect of the present invention, even if the downward swing angle, that is, the downward wind direction adjustment angle is large, the fins are formed in the opening of the lower peripheral wall, which may increase the blowing loss. At the same time, it does not disturb the upward wind direction by facing the blast on the lower surface of the outlet when swinging upward.
