Abstract

PURPOSE:To control the flow as it can be deviated to any direction, three-dimensionally, by making a bias shielding plate which is set to interrupt a part of the flow generated by a narrowed orifice of a nozzle, spirally movable along the axis of the flow route, in a flow direction control device. CONSTITUTION:In the upper stream side of a nozzle with a narrowed orifice 7, a bias shielding plate 9 which is used to interrupt the bias flow generated by the narrowed orifice 7, is supported by a rotating shaft 10 through a supporting member 11, as the plate 9 can spirally move along the axis of the flow route. In this way, the attaching position and the attaching strength of the flow against a guide wall 8 are varied, and the blow-off direction of the flow can be spirally changed to any direction, from the widely deviated direction to the front direction. Consequently, the attachment is satisfactorily performed, and the wide-angle attachment can be got.

Description

Detailed Description of the Invention The industrial field of application J relates to a flow direction control device installed at the outlet of an air conditioner, etc., for deflecting the flow from the air source in an arbitrary direction and blowing it out. It is..

The structure of the conventional example and its problems In the air conditioner that performs cooling and heating 3, the air conditioned 11
In order to make the temperature distribution uniform in the 19th room, it is desirable to control the flow direction of the air to Q~i~ during heating and horizontally during cooling. Sweet, air conditioner installation position ii+"t'4
2. Wide angle in left and right directions (I:'1ili'i
91) It's sweet.

Conventional examples for achieving this purpose include those shown in FIGS. 1 and 2. In the figure, 1a and 1bt, i guide wall (iJ in the figure: only two are shown, but there are many), 2 is a nozzle that blows out the flow, and 3 is a deflection plate rotated by a shaft 4.

Due to the flow guiding action of the deflection plate 4, the flow exiting from the nozzle is directed to the guide walls 1a, 1b (la in FIG. 1) (
q is deflected. When the deflection plate 4 is rotated, the guide rat that moves toward Ml, Rekai, etc. becomes friendly, and the blowing direction changes. Below 1. It is something that deflects the flow with 0 works,
Since the deflection plate 4 is provided in the path (r, i, fjL), it becomes a resistance to the IN, but since it also has a shape that disturbs the streamline of the flow, the (= J foil effect on the wall surface) The problem was that it was inevitable that things would get worse.

+-1 misfire of origin 1] - This solves all of the conventional problems, and wind 11
[1] It is an object of the present invention to provide a flow direction control device that deflects the flow at a wide angle downward and left and right without causing resistance and disturbing the streamlines.

The ring of intervention 1
A nozzle is installed at the exit 1'J☆1'ij of the flow path, and the nozzle is narrowed from the entire circumference with respect to the axis of the flow path, and A plan with a gradually expanding shape formed in 1) A hard 1t and a flow nozzle L which is provided on the outside of the nozzle on the -1-ffic side of the riif nozzle, and which is caused by the aperture, and the flow nozzle L which turns toward the center of the path 1ir14, and the bias shielding plate is movable in a spiral manner in the axial direction of the flow path.

With this l'f&l function, the nozzle pattern can cause

? In addition, the bias flow from other parts is generated +11"L, and the flow blown out from the nozzle results in n"HA"4 on the guide wall. As it moves in a spiral from the bias shielding plate, the position of the guide wall changes.

Furthermore, by changing the gap between the bias shielding plate and the nozzle, the strength of the flow toward the guide wall changes.As a result, the blowout flow is caused by the spiral shape of the bias shielding plate. According to the shift of 0J, the blowing direction is completely changed in a winding manner.In other words, the blowing of the flow becomes +jJ' in the intended direction three-dimensionally.

In this case, the bias shield plate is 1. of the nozzle. (
Since it is present at the outside of the nozzle, it does not create resistance to the flow and does not disturb the flow. Therefore, the wind (

DESCRIPTION OF EMBODIMENTS An embodiment of the misfire J will be explained below using FIGS. 3 to 5. In Figures 3 to 5, 5 is a flow path that induces a flow sent from a blower, etc., and 6 is a flow path l1llll1.
5a is a circular nozzle that has an aperture 7 from the entire circumference, 8 is a guide wall formed to surround the nozzle on the flow side of the nozzle 6, and gradually serves as the exit of the nozzle 6 and the starting point. The nozzle 6 has an enlarged shape.A bias shielding plate 9 is provided on the −η side of the nozzle 6 to intercept the bias flow generated by the aperture 7. (Fig. 5 shows a perspective view) This rotates around the rotation axis 10' (iy center), and is located on the outside of the nozzle near the exit [-1 of the nozzle 6, and is in contact with the aperture 7. This rotating shaft 10 is supported by a paulownia 11 protruding from the outer wall of the flow path 5, and the -IX portion 10a of the rotating shaft 10 and the supporting portion 4'OA'11 and are connected by screws.As a result, the shielding plate 9 moves in a spiral manner with respect to the axial direction of the flow path in response to rotations 1i+1110 times U).

-1. In the memorization process, the operation will be explained using FIGS. 6 to 8. First, the case where the shielding plate 9 and the nozzle 7 are closely spaced A'TL as shown in FIG. 6 will be described.

In this case, a part of the flow that enters the flow path becomes a bias flow Fb due to the throttle 7. Here, a bias flow Fb occurs on the left side of the figure, but on the right side, due to the effect of the bias shielding plate 9, the bias flow Fb is generated.
Does not occur. For this reason, the mainstream Fa is directed to the power of the guide arm IY on the right side by the bias flow Fb from the left side, and Fa
The confluence F of Fb and Fb is the right guide 11゛(ni((t, iT
I, , wide-angle deflection to the right. The deflection angle at this time can be arbitrarily set depending on the shape of the guide wall 8.

In this case, there is a gap between the shield plate 9 and the aperture 7. arise. This gap generates a flow FD opposing the bias flow FbK, which weakens the FbO force.

As a result, the force of the acoustic flow F to land on the guide wall 8 is weakened, and the deflection angle of the blowout flow becomes smaller than in the case of FIG. 6. The deflection angle increases in inverse proportion to the size of the gap.

Next, the case where the shielding plate 9 is moved to the position shown in FIG. 8 will be explained. In this case, the flow generated from the gap has almost the same strength as the bias flow Fb, and the combined flow Fb
i#J: Blows out directly without deflection.

As described above, by fully rotating the rotating shaft 10 and moving the shielding plate 9 in a spiral shape, the flow ('J') toward the guide wall 8 is
X: 'r position IIQ+ and strength change, and the blowing direction of σL can be set to any desired position in a spiral shape from a wide-angle deflection position to facing forward.

Next, other embodiments of unexploded fill will be explained using FIGS. 9 and 10. In Figure 9, tri from 1 to 11
This is similar to the first embodiment. 121-J: A protrusion provided at the inlet of the nozzle 6 and facing toward the flow side. Due to the effect of this protrusion, even if the gap between the shielding plate 9 and the aperture 7 changes, the flow FD passing through the gap is blocked by the protrusion 12, and the blowout The best flow is to arrive at guide A-X ¥8. In other words, due to the action of the protrusions, the flow with the maximum deflection angle is blown out over the entire circumference, resulting in a protrusion 1 flood.

In FIG. 10, the rotary shaft 10 is rotated by +16 by the morph 13, so that remote control using a remote control, white [F] J swing, etc. become ■f fk.

Effects of the invention
