Abstract

PURPOSE:To make it possible to perform air conditioning in a directly front direction by making respective distances from support shafts of respective louvers to points where links transmit forces to respective louvers, that is, rotational radiuses of respective pivot points, are larger as they are directed from the outer side to the center, when respective louvers are rotated horizontally. CONSTITUTION:A plurality of louvers 3' are aligned in parallel equidistantly and are pivotally supported rotatably at air discharge ports 2 with a support shaft 5. Links 4' penetrate slantly through respective louvers 3' and respective distances l1, l2, l3, l4,... from respective support shafts 5 of louvers 3', are pivotally connected by pins 6 at respective pivotal points where l1<l2<l3<l4<.... Accordingly, when respective louvers 3' are rotated outward by operating lever 7 in the direction indicated by arrow 11, since the rotational radius of each pivotal point 6' becomes larger as it approaches the center from outer side, the rotational angles of respective louvers 3' are different from each other and become theta1>theta2>theta3>theta4>.... The angles of openings to the outsides of respective louvers 3' become smaller as they go to the center from the outer sides. As a result, even when the louvers are directed horizontally, the blasting to the directly front direction of the air conditioner is carried out, and hence air conditioning toward the directly front direction of the air conditioner becomes possible.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a wind direction adjusting device for an air outlet of an air conditioner or the like.

Conventional technology Generally, in air conditioners (hereinafter referred to as air conditioners), the third
As shown in FIGS. 1 to 6, the air outlet 2 of the air conditioner 1 is provided with a plurality of louvers 3 and links 4 for interlocking the louvers. The plurality of louvers 3 are arranged in parallel at equal intervals and rotatably supported on the air outlet 2 by a support shaft 6. A link 4 passes through the intervening looper 3 and is pivotally attached at the penetrating portion with a pin 6. This bin 6 is the main pivot point. A lever 7 is attached to one of the louvers 3 so that the sill par 3 can be rotated by operating the lever.

In such a wind direction adjustment device, by operating the lever 7 and rotating each louver 3 about the support shaft 5, the direction of the air guide path 8 between each louver 3 can be directed to the left or right. The air blowing direction 9 can be changed to the left or right. As a result, air flowing in from the direction of the arrow 1o is guided to the air guide path 8 and blown out in the direction toward which it faces.

Although the right half is omitted in Figures 5 and 6, there is a symmetrical one on the right side, and by rotating the left half louver to the left and the right half louver to the right,
It can send air wider than the width of the air conditioner.

Problems to be Solved by the Invention However, in the above embodiment, if the l levers are directed to the left and right, respectively, and air is blown to the left and right of the air conditioner,
There was a problem in that air could no longer be blown directly in front of the air conditioner, and air conditioning in the direction directly in front of the air conditioner was impaired.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a wind direction adjustment device that blows air directly in front of an air conditioner even when the looper is turned to the left or right, and is also capable of air conditioning directly in front of the air conditioner.

Means for Solving the Problems In order to achieve this object, the present invention provides a plurality of loopers arranged in parallel at intervals at an air outlet and each rotatably supported on a support shaft, and It consists of links that interlock the loopers, and the distance between each of the loopers, each pivot point of the link, and each support shaft of each of the loopers is 11 degrees from the outside toward the center. When......! , ku12ku13ku14ku..., and each pivot point is arranged on the same straight line.

Operation According to this configuration, when each looper is rotated left and right, each distance from the spindle of each looper to the point where the link transmits force to each looper, that is, the radius of rotation of each pivot point, is
The rotation angle of the looper increases as it goes from the outside to the center, so when the lv-bar is turned to the left or right, the rotation angle of the looper becomes smaller as it goes from the outside to the center.

EXAMPLE Hereinafter, an example of the present invention will be described based on FIGS. 1 and 2. Note that the same numbers are used for the same parts as in the conventional example. The air outlet 2 includes a plurality of loopers 3',
A link 4' is provided for interlocking each looper.

A plurality of loopers 3' are arranged in parallel at equal intervals and rotatably supported on the air outlet 2 by a support shaft 6. Then, the link 4' passes through each looper 3' diagonally, and each looper 3'
Each distance from each spindle 5 of 11-12, 13, 14*...
. . is pivotally connected by the bin 6 at each pivot point where 11<12<13×14. Therefore, when each looper 3' is rotated outward (arrow 11) by operating the lever 7 in the direction of arrow 11,
Since the rotation radius of each pivot point 6' increases from the outside to the center, the rotation angle of each looper 3' is different from 6, 〉θ2〉θ3〉θ4〉..., and each looper 3' has a different rotation angle. The outward opening angle of ′ becomes smaller from the outside to the center. As a result, the air flowing in from the direction of arrow 10 is blown out through each air guide path 8 in the direction of arrows 12 to 15, so even when the looper is turned left or right, the air is blown directly in front of the air conditioner. This allows for air conditioning directly in front of the building.

Effects of the Invention As is clear from the above description, the present invention includes a plurality of loopers arranged in parallel at intervals at an air outlet and each rotatably supported by a support shaft, each of the loopers and the above. It consists of links that interlock each looper, and the distance between each pivot point between each looper and each link and each support shaft of each looper is 111, 12.1!3. from the outside toward the center.
14. When ・・・・・・11 ku 12 ku 13 ku 14
This is a wind direction adjustment device that is characterized by the fact that each pivot point is aligned on the same straight line, so even when the looper is turned to the left or right, the air is blown directly in front of the air conditioner. Air conditioning directly in front is also possible. Therefore, it is extremely effective in performing air conditioning over a wide area, including directly in front of the air conditioner.
