Abstract

PURPOSE:To introduce a wind discharged through a discharge port in an arbitrary direction by a method wherein gears for drive are respectively mounted to the one ends of the rotary shafts of wind direction changing blades, and a gear for transmission to transmit movement of the one gear for drive to the other gear for drive is provided. CONSTITUTION:When, through running of a drive motor 9, a rotary shaft 10 is rotated in the direction of an arrow mark, a lower wind direction changing blade 5 is first rotated downward. Along with rotation of the lower wind direc tion varying blade, the one gear 15 for drive coupled directly to a left rotary shaft 19 of the lower wind direction varying blade 5 is rotated in the direction of an arrow mark. Rotation of the one gear 15 for drive is transmitted to the other gear 16 for drive through a gear 17 for transmission. This transmission also causes downward rotation of an upper wind direction changing plate 6. Thus, a delivery port 7 can be completely closed with the changing blades 5 and 6, and the changing blades can be brought into an approximate horizontal state in a discharge port 7. Further, the rotation angle of the varying plate is approximate 140 deg..

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a wind direction changing device provided at an outlet of an air conditioner or the like.

(b) Prior Art The air outlet of an air conditioner or the like often has a plurality of wind guide plates arranged in parallel, as shown in Japanese Utility Model Publication No. 61-20439. In such a wind direction changing device, a gear is attached to one end of the rotating shaft of each wind guide plate, and these gears are connected with a belt, or a pin is set on each rotating shaft at a position offset from this axis. The pieces are connected, and the bottles are connected with connecting rods such as links.

When one wind guide plate is moved, the remaining wind guide plates are also moved in accordance with this movement, so that the direction of the wind discharged from the outlet can be changed.

(c) Problems to be Solved by the Invention In the wind direction changing device having such a structure, the wind direction changing plates always move in the same direction, so that the wind from the outlet cannot be diffused.

In addition, in devices where the wind guide plate is moved by a belt, if the belt slips or loosens, the wind guide plates may become misaligned with each other, and if the tension of the belt is too strong, the operation of the wind guide plate may become difficult. Sometimes it became difficult to do.

On the other hand, in the case where the wind guide plate is moved by a connecting rod, the wind guide plate moves while maintaining a substantially parallel state when the extension lines connecting the spindle of the top and the rotating shaft of the wind guide plate intersect. However, in the state where the above-mentioned extension lines are approximately parallel, even if one of the pieces rotates (even if one of the wind guide plates rotates) due to the clearance of the joint between the bottle and the connecting rod, the The movement may not be accurately transmitted to the other piece via the connecting rod (the other wind guide plate may not rotate, or the direction of rotation of the other wind guide plate may not be determined). Therefore, in a structure in which the wind guide plate is not moved by a connecting rod, the rotation angle of the wind guide plate cannot be large (90 degrees or more).

An object of the present invention is to increase the rotation angle of a plurality of parallel wind direction changing plates and to reduce the deviation in the direction of the rotation force.

Furthermore, the purpose is to diffuse the wind from the discharge port.

(d) Means for Solving the Problem - In order to achieve this object, the present invention provides a drive gear at one end of the rotating shaft of a plurality of wind direction changing blades arranged in parallel, and transmits both gears. They are connected by mechanical gears. Further, the downward rotation angle of the downward wind direction changing blade is made larger than the downward rotation angle of the upper air direction changing blade.

(E) Effect When one wind direction changing blade is rotated, the movement is transmitted to the driving gear and transmission gear of the rotating shaft of one wind guide plate, and the driving gear of the rotating shaft of the other wind direction changing blade, This other wind direction changing blade moves.

Further, by setting a large downward angle of the downward wind direction changing plate, both changing blades are in a state of spreading toward the end, and the wind discharged from the air outlet is diffused from this air outlet.

(F) Embodiment In Fig. 4, 1 is an indoor unit (air conditioner) of a separate type air conditioner, which includes a main body 2, a front cover 3 attached to the front of this main body 2, and a front cover of this cover. A housing is formed from the attached suction panel 4. 5,
Reference numeral 6 denotes two wind direction changing blades provided on the horizontally elongated blow-off lower. When the operation of the indoor unit 1 is stopped, the discharge lower is almost completely closed by the upper and lower air direction changing vanes 5 and 6, as shown in FIG. 5, to improve the appearance when the indoor unit 1 is stopped. On the other hand, when the indoor unit is operating, the fifth
As shown by solid line arrows in the figures and FIG. 6, the two wind direction changing blades 5 and 6 rotate while maintaining a substantially parallel state.

FIG. 2 shows a drive device for these two wind direction changing blades 5 and 6, 8 is a blow-off frame forming the blow-off lower, 9 is a drive motor arranged on the right side of the blow-off frame 8, and its rotation axis 10 is It is directly connected to the right rotation shaft 11 of the downward wind direction changing blade 5. 12
is a boss erected on the left outer surface of the blow-off frame 8, and a mounting plate 13 is fixed to this boss with screws 14. As shown in FIG. 3, this mounting plate 13 has one driving gear 15,
The other drive gear 16 and a transmission gear 17 that meshes with both gears 15 and 16 are rotatably supported. The rotating shaft 18 of one driving gear 15 is directly connected to the left rotating shaft 19 of the lower wind direction changing blade 5, and the rotating shaft 20 of the other driving gear 16 is directly connected to the left rotating shaft 21 of the upper wind direction changing blade 6. ing.

Further, the right rotation shaft 22 of the upper wind direction changing blade 6 is rotatably fixed to the blowing frame 8.

Therefore, when the drive motor 9 is operated and its rotating shaft 10 is rotated in the direction of the solid arrow in FIG. 2, the downward wind direction changing blade 5 first rotates downward. Along with this, one of the drive gears 15 directly connected to the left rotating shaft 19 of the downward wind direction changing blade 5 rotates in the direction of the solid line arrow in FIGS. 1 and 2. The rotation of this one driving gear 15 is caused by the transmission gear 1
7 to the other driving gear 16. As a result, the upper air direction changing plate 6 also rotates downward.

In this way, the movement of the lower wind direction changing blade 5 is controlled by the two drive gears 15 and 16 and the transmission gear 17.
Since the change blades 5 and 6 rotate in a substantially parallel state, the rotation angle can be wide. That is, it is possible to completely close the discharge lower chamber with these changing vanes 5 and 6 (see FIG. 5), or to make these changing vanes almost horizontal within the air outlet 7 (see FIG. 6), The rotation angle of these change plates is approximately 140°.

The mounting plate 13 to which the gears 15, 16, and 17 described above are attached is provided on the right side of the blow-off frame 8, and the drive motor 9
and the mounting plate 13 may be put together on one side of the blow-off frame 8.

In this way, the driving parts of the upper and lower wind direction changing blades 5 and 6 are grouped together on the right side, and even if the changing blade is slightly twisted due to the rotation of both wind direction changing blades, both wind direction changing blades are always kept in the same position. Rotate in parallel.

FIG. 7 shows the right side plate 23 of the blow-off frame 8, and 24 is an upper guide lip into which the right rotation shaft 22 of the upper air direction changing blade 6 is inserted. The protrusion 25 (omitted in FIG. 2) of the right rotation shaft 22 moves within the upper guide lip 24 as indicated by the solid line arrow by the rotation of the upper wind direction changing blade 6. 26 is a lower guide lip into which the right rotation shaft 11 of the downwind changing blade 5 is inserted. The protrusion 27 (omitted in FIG. 2) of the right rotation shaft 11 moves within the lower gaff drip 26 as indicated by the solid arrow by the rotation of the downwind changing blade 5. 2B is a stopper fitted between the lower guide lip 26 and the protrusion 27 of the right rotation shaft 11. By providing this stopper 28, the rotation range A of both rotation shafts 11 and 22 is determined to be approximately the same. , the rotational range of the upper and lower wind changing blades 6, 5 changes from the state shown in FIG. 5 (the state of both rotating shafts is shown in FIG. 7) to the state shown in FIG.

Here, the reason why the stopper 2B is provided is the downwind changing blade 5.
This is to provide another embodiment of the wind direction changing device in which the downward rotation angle is increased.

FIG. 8 shows the wind direction changing device 29, with both rotating shafts 11.
Attach the drive motors 30 and 31 individually to 22, remove the mounting plate 13 (see Fig. 2), and attach the two differential rotation shafts 19.
．． 21 are supported by bearings 32, and the above-mentioned stopper 2B is removed. The wind direction changing blades 5 and 6 are moved by respective drive motors 30 and 31. In particular, by removing the stopper 2B, the downward changing blade 5 also rotates downward from the closed state of the blow-off lower as shown by the solid line 8-arrow in FIG. The protrusion 27 is located at the portion 32 where the stopper is removed. That is, the controller sets the downward rotation angle of the downwind direction changing blade 5 to be larger than the downward rotation angle of the upwind direction changing blade 6. Here, the controller includes two drive motors 30 and 31.
, two guide lips 25 and 26, a protrusion 27, a positioning piece (described later), and a positioning lip (described later). In Figure 11, 3
3 is a positioning piece for this downwind changing blade 5, and the rotating shaft 1
Fixed to 1. When the downward changing blade 5 closes the blower lower, the protrusion 34 of the positioning piece 33 fits into the positioning lip 35, even if there is an error in the rotation angle of the rotation shaft of the drive motor 30. , this error is corrected by the downward changing blade 5 with the blowing lower lower closed.

In this way, since the downwind changing blade 5 also rotates downward, the dual-purpose machines 5 and 6 are tapered as shown in FIG. 12, so that the wind discharged from the blowout lower is concentrated in one place. Alternatively, as shown in FIG. 13, the dual-purpose machines 5 and 6 can be spread out to spread the air discharged from the blow-off lower.

(G) Effects of the Invention As described above, the present invention arranges a plurality of wind direction changing blades in parallel at the air outlet, and provides a driving gear at one end of the rotating shaft of each of these changing blades. Since the wind direction changing blades are connected by a transmission gear, the multiple wind direction changing blades always rotate while maintaining a parallel state, and the wind discharged from the outlet can be guided in any direction. Since the plurality of wind direction changing blades are rotated, the rotation angle of these changing blades can be set large, and the air outlet can be completely closed to improve the appearance when the operation is stopped.

Furthermore, since the downward rotation angle of the downward wind direction change blade is made larger than the downward rotation angle of the upper wind direction change blade, when the air outlet is provided above, the wind is diffused downward from this air outlet. be able to.
