[Industrial applications]

 The present invention relates to an air outlet structure for an air-conditioning register of an automobile or the like.

[0002]

[Prior Art]

 Conventional air outlet structures for air-conditioning registers of automobiles of this type are, for example, Japanese Utility Model Publication No. 3-27237, Japanese Utility Model Publication No. 61-133747, Japanese Utility Model Publication No. 56-60039, and Japanese Utility Model Publication No. There is a publication of 60-155844.

[0003]

[Problems to be solved by the device]

 However, in the above-mentioned conventional publications, Japanese Utility Model Publication No. 3-27237 and Japanese Utility Model Publication No. 61-133747, the noise level of the register is relatively high, especially when the air is spread, and the movable blade is tilted. As a result, the pressure loss increases, leading to a decrease in the flow rate and flow velocity, resulting in a lack of wideness and the problem of impairing the air conditioning function.Moreover, there are many structures with flow separation, and the inner wall of the ventilation passage of the barrel Since it is almost straight, the directivity of air is lacking, and the structure is complicated and the number of parts is large, resulting in poor assembly and high cost.

Further, in Japanese Utility Model Laid-Open No. 56-60039 and Japanese Utility Model Laid-Open No. 60-155844, there are many structures in the center of the ventilation passage, and flow separation easily occurs due to the structure. Since the noise caused by wind noise is large and the pressure resistance is large, there is a problem that the flow rate and the flow velocity decrease and the air conditioning function is impaired.

The present invention has been made to solve the above-mentioned conventional problems, and an object of the present invention is to provide an air outlet structure of a register having a simple structure, excellent directivity, and low noise. Is.

[0006]

Means for Solving the Problems In order to solve the above technical problems, the present invention concentrically corresponds to a retainer portion in which an air opening is formed by cutting out a part of a hollow sphere and the air opening. A duct is formed on the retainer, and a retainer is provided. The retainer portion has a circular disk formed on the diameter side of both hemispheres of a hollow sphere that is rotatably fitted in the retainer section and is divided into two. The outer surface of the hemisphere is cut out in the plane perpendicular to the front and back to form a pair of contraction barrels consisting of a hemispherical zone part having a small diameter outlet and a large diameter inlet, and It exists in the air outlet structure of the register in which the upper and lower contraction barrels are rotatably connected to each other via the center axis of the disc.

[0007]

[Action]

 With the above configuration, the focused air is jetted by aligning the outlets of the upper and lower contraction barrels with each other, and the diffused air is diffused by displacing and rotating the outlets through the upper and lower contraction barrels. The wind blows.

[0008]

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a sectional view of a register 1, which is composed of 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 portion 4 having a predetermined diameter, and a side corresponding to the air opening portion 4 is formed. The duct portion 5 is integrally formed concentrically, and the felt 6 is attached to the inner peripheral surface of the retainer portion 3, and the barrel 7 is rotatably attached through the felt 6. .

The barrel 7 is constructed by symmetrically contracting flow barrels 8 and 9 obtained by dividing a hollow sphere fitted inside the retainer portion 3 into two parts. As shown in FIG. A disk 10 is formed, a part of the outer contour of the hemisphere is cut out to open an air outlet 11, and a cutout is formed at a position rearward from the center of the disk 10 in parallel with the air outlet 11. An inlet 12 that is larger than the outlet 11 is formed to form a hemispherical band portion 13, and the outlet 10 side of the disc 10 is a knob portion 14.

Further, as shown in FIG. 2, the inner surface 15 of the hemispherical zone 13 has a concave surface 15a with a predetermined radius on the inlet 12 side and a convex surface 15b with a predetermined radius on the outlet 11 side. The inner side surface 15 is formed so as to be continuous and has a substantially sine wave shape. The contraction barrels 8 and 9 formed in this way have, for example, a bearing hole 16 penetrating the center of the disc 10 of the contraction barrel 9, and the center of the disc 10 of the contraction barrel 8 described above. A shaft 17 that rotatably fits into the shaft receiving hole 16 is projected and coupled to each other as shown in FIGS. 3 and 4, and in this coupled state, the shaft 17 is fitted into the retainer portion 3 of the retainer 2 to The outlets 11 are arranged in the aligned state, that is, the center lines C1 and C2 of the contraction barrels 8 and 9 are aligned in the axial direction of the duct portion 5 and are arranged on the air opening 4 side. In this state, the upper and lower contraction barrels 8 and 9 are rotatably provided via a shaft 17.

In the register 1 thus formed, as shown in FIG. 5, when the center lines C1 and C2 of the upper and lower contraction barrels 8 and 9 are aligned and the outlets 11 are vertically aligned, The air flow F from the duct portion 5 side is contracted by the inner surface 15 of the hemispherical zone portion 13 by the inlet 12, and is ejected from the outlet 11 as focused spot-like air. Further, at this time, the energy component of the flow due to the contraction is excellent in the direction of the center lines C1 and C2 of the upper and lower contraction barrels 8 and 9, so that the directivity is improved and the air can be carried far. . 6 shows the distribution of the flow velocity of the focused jet in the distance from the outlet 11 in FIG. 5, the solid line is the distribution immediately downstream of the outlet 11, and the dashed-dotted line is about 400 mm apart. , And the alternate long and two short dashes line shows the distribution at a position approximately 800 mm apart.

Further, FIG. 7 shows a state in which the upper and lower contraction barrels 8 and 9 are rotated, for example, to the left and right by a relative angle α from the state of FIG. The air jetted from the blowout port 11 of 9 is divided into the angles α formed by the respective centerlines C1 and C2 to form a jet having a twin-shaped flow velocity distribution of the jets F1 and F2 (shown by the solid line in FIG. 8). These jets F1 and F2 are then diffused and developed into wide jets as shown by the one-dot chain line and two-dot chain line in FIG. In this way, by changing the relative angles of the upper and lower contraction barrels 8 and 9, it is possible to continuously switch from the focused wind to the diffused wind and from the diffused wind to the focused wind. 8 shows the distribution of the flow velocity of the focused jet in the distance from the outlet 11 in FIG. 7, the solid line is the distribution immediately downstream of the outlet 11, and the dashed-dotted line is at a position 400 mm apart. , And the chain double-dashed line shows the distribution at a position approximately 800 mm apart.

Further, FIG. 9 shows a state in which the disk 10 is rotated 90 degrees from the state of FIG. 5 or 7 and the air opening 4 is closed, whereby the air flow F can be shut off. it can.

As described above, in the register 1 of this embodiment, the duct portion 5 is formed concentrically in correspondence with the retainer portion 3 and the air opening portion 4 which are formed by cutting out a part of the hollow sphere to form the air opening portion 4. Is provided with a retainer 2, and a disc 10 is formed on the retainer portion 3 on the diameter side of both hemispheres obtained by splitting a hollow sphere into which the retainer portion 3 is rotatably fitted. Forming a pair of contraction barrels 8 and 9 consisting of a hemispherical zone 13 having a small-diameter outlet 11 and a large-diameter inlet 12 formed by notching the outer surface of the hemisphere in the vertical direction. At the same time, since the upper and lower contraction barrels 8 and 9 are rotatably connected to each other via the shaft 17 at the center of the disk 10, the structure is extremely simple and can be used as a normal register. The wing that can be seen is a single sheet on which the disk 10 is superposed, so the air flow Since there are few members that interfere with F, noise due to wind noise can be reduced, and since the ventilation path is smooth, pressure resistance is small, and the flow rate and flow velocity when changing from diffused air to focused air flow are reduced. As a result, the airflow F reaches farther in the focused wind compared to the conventional one, so that the air conditioning performance and the pointing performance are also improved. In addition, it has excellent design and is suitable for automobile interiors and has good operability.

[Effect of the device]

 Since the present invention is configured as described above, it has an extremely simple configuration, and the blade seen in a normal register is a single disk in which discs are superposed, so that it is a member that interferes with the air flow. Since there is less wind noise, noise due to wind noise can be reduced, and because the ventilation path is smooth, the pressure resistance is small, and there is no decrease in the flow rate or flow velocity when changing from diffused air to focused air. Compared to the air conditioner, the air flow reaches far in the case of focused wind, so the air conditioning performance and directivity performance are also improved. In addition, it has an excellent design and is suitable for the interior of automobiles and has good operability.
