DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a sectional view of a register 1 which comprises a retainer 2 and a barrel 7.

In this retainer 2, a hollow spherical retainer portion 3 having a predetermined diameter is partially cut out to form an air opening 4 having a predetermined diameter, and a side corresponding to the air opening 4 is formed on the side corresponding to the air opening 4. While the duct part 5 is integrally formed concentrically,
A felt 6 is adhered to an inner peripheral surface of the retainer portion 3, and a barrel 7 is rotatably mounted via the felt 6.

The barrel 7 is formed of a hollow sphere 8 fitted inside the retainer portion 3, and as shown in FIG. 2, a disk 9 is formed in the diameter direction of the hollow sphere 8, and the hollow portion is vertically extended. At the same time, the upper and lower shells 10 are vertically notched at a position separated by a predetermined dimension L1 from the center C1 of the disk 9 with the disk 9 of the hollow sphere 8 as a boundary. 11a and 11b are opened, and the outlets 11a and 11b
Large openings 12a, 12b are cut in the vertical direction at a position behind the center C1 of the disk 9 by a predetermined distance L2 from the center C1.
Are formed, and the upper and lower hemispherical band portions 13a and 13b are connected to form a spherical band portion 13.

Further, as shown in FIG. 2, the cross-sectional shape of the inner side surface 14 of each of the hemispherical bands 13a, 13b is larger than the opening edges of the small openings 11a, 11b.
A predetermined range from the edges of the small openings 11a and 11b is formed on a plane parallel to the central axis C, and a hyperboloid whose curvature radius becomes gradually smaller toward the larger openings 12a and 12b. Hemispherical portions 13a, 13b
Is formed in a substantially wing shape in cross section, and is formed in a drawing shape by a hyperboloid-shaped inner surface 14 from the large openings 12a, 12b toward the small openings 11a, 11b.

A substantially streamlined sphere 15 is integrally formed in a bulging shape above and below the central axis C on the side of the large openings 12a and 12b of the disk 9. A part of the substantially streamlined sphere 15 protrudes outward from the large openings 12a and 12b, and the curved surface 15a of the substantially streamlined sphere 15 located at the large openings 12a and 12b and the R of the large openings 12a and 12b. The surface 14b is formed so as to expand from the small openings 11a and 11b.

The barrel 7 formed as described above is rotatably fitted to the retainer 3 of the retainer 2 and, for example, as shown in FIG.
By setting the small openings 11a and 11b on the side of the air opening 4 as shown in FIG. 7, the substantially streamlined sphere 15 is positioned on the upstream side, and the flow of air F is the same as the sphere 15, the disc 9 and the hemispherical band 13a, 1
3b, the wind speed increases while suppressing the turbulence intensity in the lateral direction, through the reduced flow path formed by the hyperboloid inner surface 14;
It is jetted toward the passenger compartment as a focused jet with a narrow jet width and a high flow velocity. Further, at this time, since the sphere 15 has a three-dimensional streamline shape, the separation of the air flow F is small, thereby suppressing the generation of noise. Further, when the air flow F passes through the barrel 7, the flow is reduced and the dynamic pressure is increased, so that the directivity can be improved and the air can be carried far. FIG. 6 shows the distribution of the flow velocity at a distance from the small opening 11 of the focused jet in FIG.
The solid line indicates the distribution at a position immediately downstream of the small opening 11, the dashed line indicates the distribution at a position approximately 400 mm away, and the two-dot chain line indicates the distribution at a position approximately 800 mm away. .

FIG. 7 shows the state of FIG.
When the large openings 12a and 12b are turned to the air opening 4 side in a state of being rotated by 80 degrees, the air flow F in this state causes the hyperboloid inner surface 14 and the disk 9 of the hemispherical bands 13a and 13b to flow. The gas is ejected toward the passenger compartment while decreasing the flow velocity in the enlarged flow path formed by the flow path and the substantially streamlined sphere 15. At this time, since the substantially streamlined sphere 15 is located on the side of the large openings 12a and 12b, the flow F of the air flows along the expanding direction of the hyperboloid inner surface 14 of the hemispherical bands 13a and 13b. Since the jet flows easily, the jet easily expands. Further, since the downstream side of the substantially streamline sphere 15 is a spherical surface, a large-scale vortex is induced in the wake behind the jet, and the jet is accelerated to become a diffusion jet. FIG. 8 shows the distribution of the flow velocity of the diffusion jet at a distance from the large opening 12 in FIG. 7, and the solid line is the distribution at a position immediately downstream of the large opening 12, and the one-dot chain line is almost The distribution at a position 400 mm away, and the two-dot chain line shows the distribution at a position approximately 800 mm away.

FIG. 9 shows a state in which the disk 9 is turned by 90 degrees from the state shown in FIG. 5 or FIG. 7 to close the air opening 4, whereby the air flow F can be blocked. it can.

FIGS. 10 and 11 show another embodiment. In this embodiment, instead of the substantially streamlined sphere 15 of the above embodiment, a substantially streamlined sphere 16 is vertically Are formed into two separate hemispheres 17 and 18 and, for example, a connecting pin 18b of a predetermined length is formed on a mating surface 18a of one hemisphere 18 and the other hemisphere 1 is formed.
7, a fitting hole (not shown) is formed in the mating surface 17a, and a long hole 9a of a predetermined length through which the coupling pin 18b is slidably inserted along the center line C is formed on the disk 9 side. A substantially streamlined sphere 16 is provided so as to be movable along the center line C. The other configuration is the same as the above embodiment. Therefore, in this embodiment, particularly, the large openings 12a, 12b are located on the air opening 4 side, and the upper and lower hemispheres 17, 18 are moved and adjusted along the long hole 9a via the coupling pin 18b. The large openings 12a, 1
2b, the shape of the ventilation path is changed, and the spread of the diffused wind can be adjusted. Also, the small openings 11a, 11
By setting b to the side of the air opening 4, a focused wind can be obtained in the same manner as in the above embodiment.

FIGS. 12 and 13 show another embodiment of the above-mentioned substantially streamlined sphere 16. The barrel 19 shown in FIG.
Is mainly composed of a spherical band portion 20 having a small opening 21 and a large opening portion 22 as in the above-described embodiment.
Reference numeral 3 denotes a convex surface having a predetermined diameter on the small opening 21 side of the R surface 24a.
Is formed in a concave shape with a predetermined diameter continuously from the R surface 24a to form a wing-shaped cross-section. The support shafts 25 are provided at an interval of degrees.
Of the support shaft 2 having a predetermined length from the intersection of
The support shaft 26 has a substantially streamline sphere 27 slidably mounted thereon.

The barrel 19 provided in this manner has a small opening 21 in the retainer portion 3 of the retainer 2 and an air opening 4.
In this state, the substantially streamlined sphere 27 is moved along the support shaft 26 to the inside of the small opening 21 as shown in FIG. By setting to, a focused wind can be obtained.
As shown in FIG. 3, diffused air can be obtained by moving the small opening 21 to the outside position along the support shaft 26 to the illustrated position. In this embodiment, the diffusion wind and the focused wind can be obtained by moving the substantially streamlined sphere 27 with respect to the air flow F without rotating the barrel 19.

Instead of the support shaft 25 and the support shaft 26, a disk 9 having a long hole 9a is provided integrally with the barrel 19, and the hemispheres 17, 18 are attached. , A diffused wind and a focused wind can be obtained in the same manner.

[0020]

[Effect of the Invention] Since the above configuration is adopted,
With a very simple configuration, there is only one disk equivalent to the wing found in a normal register, and there are few members that interfere with air flow, so noise due to wind noise can be reduced and the ventilation path is smooth. Therefore, the pressure resistance is small,
In particular, the decrease in flow rate and flow velocity when focusing wind is small,
Since the air flow reaches far away, the air conditioning performance and the directivity are also improved. In addition, it has excellent design and is most suitable for interior of automobiles, and has good operability.
