Abstract

PURPOSE:To adjust blow-off air speed under a constant blow-off airflow amount by a structure wherein the sectional area of the opening of a blow-off port is expanded and contracted freely. CONSTITUTION:During normal operation, a blow-off air speed changing vane 11 is held at substantially horizontal position to keep the sectional area of the opening at a predetermined value. The air speed at the section 2 of the opening of the blow-off port 1 is low and low noise may be maintained. When the high air speed is requested, the vane 11 is pivoted toward the inside of the section 2 of the opening about a hinge joint 10 to decrease the sectional area of the opening. Adjustment of airflow direction in up-and-down direction is effected by pivoting first blow-off airflow direction changing vane 18 about a supporting shaft 21 while the adjustment of the same in left-and-right direction is effected by pivoting the second blow-off airflow direction changing vane 23 about the supporting shaft 22 along the desired airflow direction. Thus, the blow-off air speed may be adjusted variably under a constant airflow amount while the desired blow-off airflow direction is also available under the constant airflow amount.

Detailed Description of the Invention [Technical Field of the Invention] The present invention relates to an air outlet structure for an air conditioner, and in particular, it is possible to maintain a constant output air volume by changing the opening cross-sectional area of the outlet. This relates to an outlet structure that can adjust the outlet air speed.

[Technical background of the invention and its problems]

Generally, the air outlet structure of an air conditioner such as a room air conditioner is as shown in FIG. Horizontal slat 4 and vertical slat 5
are assembled together to form a lattice. Horizontal feathers.

Both ends of the root plate 4 are pivotally supported by the partition wall 3, and the root plate 4 is constructed so that the direction of the wind flowing through the opening cross section 2 can be adjusted completely up and down by rotating and swinging in the vertical direction. On the other hand, a notch 6 is provided in the vertical blade plate 5, and this notch 6'
It is pivotally supported by the horizontal blade plate 4 through the lc, and rotates and swings in the left and right directions while following the rotation and rocking of the horizontal blade plate 4, so that the direction of the wind flowing through the opening cross section 2 can be adjusted left and right. It is composed of

Further, in FIG. 2, the partition wall 3 itself that partitions the opening cross section 2 is pivotally supported on the nozzle (not shown) side of the air conditioner and is configured to rotate and swing in the vertical direction. Therefore, the vertical direction of the wind is adjusted by the rotational movement of the partition wall 3, and the horizontal blade plate 4 is fixed to the partition wall 3 and simply follows the rotational movement of the partition wall 3. Adjustment of the wind direction to the left and right is also performed by the vertical blade plate 5, and the vertical blade plate 5 is replaced by the horizontal blade plate 4, as in the case of FIG. blower (not shown)
The wind speed at the opening cross section 2 of the outlet 1 is determined in advance based on the air blowing capacity, and the opening cross sectional area is determined. Since the cross-sectional area of the opening that lowers the wind speed is set to be large, there is a problem in that the sense of wind speed is generally not felt.

Generally, when adjusting the wind speed, a blower (not shown) is used.
It is possible to adjust the number of rotations of the air conditioner, but this is only a method of adjusting the air volume, and it is not possible to adjust the air speed with a constant air volume.For example, if the shape of the room to be air-conditioned is long and narrow compared to its volume. There was a problem that the conditioned air could not reach every corner of the room and could only be air conditioned partially.

[Purpose of the invention]

The present invention has been devised in view of the above problems and to effectively solve them.

An object of the present invention is to provide an air conditioner outlet structure in which the outlet air velocity can be adjusted while the outlet air volume remains constant by fully expanding and contracting the opening cross-sectional area of the outlet.

[Embodiments of the invention]

Hereinafter, a preferred embodiment of the present invention will be described with reference to the accompanying drawings.

The air outlet structure of the air conditioner according to the present invention is as shown in FIG. It is divided by a lower partition plate 8 that constitutes the structure, and side partition plates 9 that make up all the partition walls on both sides.

The upper partition plate 7#lc is provided with variable blowing air speed vanes 11 which can be expanded in the vertical direction via a hinge joint 10 on the blowing side thereof. The variable blowing air speed vane 11 is formed of a flat blade plate so as to expand or pivot in the direction of closing the blowing outlet 1 via the hinge joint 10 to expand or contract the cross-sectional area of the opening.

In addition, in the illustrated example, the upper partition plate γ is separated on the outlet side, and the separated divided plate 12 is connected to the hinge joint 1.
The output wind speed O that is pivoted through 0 and expands and moves in the vertical direction
It constitutes the J-blade 11.

In addition, the above-mentioned variable blowing wind speed vanes 11 are mounted on the partition wall plates 9 of both J parts.
A guide path 14 is formed along the turning locus on the free end 13 side of the blade, and a guide path 14 is secured to the guide path 14 by engaging portions 16 provided at both ends 15 of the variable blowing speed vane 11. The variable blade 11 is configured to be Vc-shaped so that it can be rotated and deployed while being guided. The guide path 11-j is formed by a hole 17 or a groove formed in the shape of a circular bar in each side partition plate 9.

In addition, in the recessed center of the opening ~1 side 2, it is divided into upper and lower parts,
A first variable blowing air direction vane 18 configured in the horizontal direction is provided so as to be transferred to the translation side.

The first variable air flow blade 18 is composed of a horizontal portion 19 and a rotating arm 2u integrally formed at both ends 27 of the horizontal portion 19. The rotating arm 20 is pivoted to the side partition wall plate 9. 21.

Further, the first variable air flow blade 181C is located at this horizontal portion 19.
Second variable blowing air direction vanes 23 are provided around the pivot shaft 22 at appropriate intervals and pivotable or swingable in a direction perpendicular to this.

As shown in FIG. 4, each of the second variable blowing wind direction vanes 23 has a top portion so that its top 24 does not hit the variable blowing wind speed vane 11 when the first variable blowing wind direction vane 18 moves from the downstream side to the blowing side. An arcuate notch 26 is formed from 24 to the outlet shoulder 25Vc.

Next, the operation of this embodiment will be described.

During normal operation, that is, when blowing out the view at a low wind speed, the variable blowout speed vane 11 is held approximately horizontally, as shown in FIG. 3, and maintained at a predetermined setting value based on the opening cross-sectional area. do.

Therefore, the wind speed at the opening cross section 2 of the air outlet 1 can be made low, and quiet operation with low noise can be maintained.

When a high wind speed is required, as shown in FIG. 4, the variable blowing speed vane 11' is rotated inward of the opening cross section 2 around the t-hinge joint 10 to reduce the opening cross-sectional area. Since the rotational speed of the blower (not shown) is not controlled, assuming that the air volume is constant, the harmonized qi will reach far from the opening 1.

The wind speed can be adjusted as described above by the variable outlet wind speed vane 11, but the wind direction can be adjusted by the variable outlet wind velocity vane 1.
8.23 as follows.

First, adjustment in the vertical direction is performed by adjusting the first blowing air direction OJ'f. When this occurs, the wind direction will be directed downwards, and when transferred to the upstream side, the VC will be able to turn directly in front of you and howl.

Further, to the left and right, there is a second variable air blowing blade 23'f: it is rotated around the pivot shaft 22 along the desired wind direction.

The first and second variable blowing air direction vanes 18.23 do not interfere with their respective movements. In addition, the blowout wind speed variable blade 1
1 and the respective variable blowing air direction vanes 18.degree. 23 do not interfere with each other.

In this embodiment, the variable air speed vane 11 is provided on the upper partition plate 1 of the air outlet 1, but as shown in No. 5 (2),
The variable blowing air speed vanes 11't-may be provided on both upper and lower corner wall plates γ and 8 of the blowing outlet 1, in this case.

Since the cross-sectional area of the opening can be made even smaller than in the embodiments described above, higher wind speeds can be obtained.
