[Purpose of the invention]

[0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner having an improved wind direction adjusting mechanism for adjusting the direction of a blown wind.

[0003]

2. Description of the Related Art Conventionally, an air conditioner of this type has a wind direction adjusting mechanism for adjusting the wind direction of blown air, and a plurality of wind direction plates are provided at a required pitch at an outlet for blowing temperature-controlled air such as cold air or hot air. The swing direction of the blown wind is controlled by manually or motively changing the swing angle of the wind direction plate.

FIG. 3 shows a conventional wind direction adjusting mechanism 1 for power operation.
Is shown in a schematic diagram when viewed from a plane, for example, a plurality of rectangular plate-shaped wind direction plates 3, 3... 4, and the inner ends of the wind direction plates 3 are provided by pins 4 so as to be able to swing around their axes as shown in FIG.

The free ends of the wind direction plates 3 are connected by connecting rods 5 extending in the direction in which the wind direction plates 3, 3... Are arranged in parallel, and one end of each of the connecting rods 5 is connected via a crank mechanism (not shown) or the like. To a motor 6 such as a step motor.

However, in this wind direction adjusting mechanism 1, the connecting rod 5
Can be adjusted only in the same direction at all times.

Therefore, in another conventional wind direction adjusting mechanism 7 shown in FIG. 5, the connecting rod 5 is divided into, for example, left and right 5a and 5b, and these right and left connecting rods 5a and 5b are
a and 6b are separately driven.

[0008]

However, such a conventional wind direction adjusting mechanism 7 can blow out the temperature-controlled air to the right and left, respectively.
b and a crank mechanism, and control means for remotely controlling the motors 6a and 6b separately by a remote controller or the like (not shown) is required. This increases the number of parts, complicates the configuration, and reduces the cost. However, there is a problem that the bulk increases.

On the other hand, when the swing angle of the wind direction plate 3 is manually operated, there is a remarkable inconvenience that the remote operation cannot be performed by the above-mentioned remote controller or the like.

Therefore, the present invention has been made in view of such circumstances, and its purpose is to make it possible to automatically remotely control the swing angle of the wind direction plate with a simple configuration and to control the swing angle by manual operation at a low cost. It is to provide a simple air conditioner. [Structure of device]

[0011]

The present invention is configured as follows in order to solve the above-mentioned problems.

That is, the present invention provides an air conditioner in which a plurality of wind direction plates are swingably provided at an air outlet, the plurality of wind direction plates are divided into a plurality of sets, and each of the sets is linked to each other by a connecting rod so as to be freely operable. A plurality of grooves are connected to an operating member driven by a remotely controllable drive source along a swing direction of the wind direction plate, and at least one of each set of wind directions is provided in a part of the continuous grooves. The locking projection of the plate is detachably engaged.

[0013]

When an operation of a drive source such as a motor is remotely controlled by a remote controller or the like, an operation member is driven. For this reason, the wind direction plate which engages the locking projection with a part of the continuous groove of the operating member swings, and the other wind direction plate connected to this wind direction plate by the connecting member also forms another set. Swings in conjunction.

Therefore, the wind direction of the temperature-controlled air blown out from the outlet is controlled by the swing angle of these wind direction plates.

Further, by forcibly swinging the wind direction plate by manual operation against the locking force between the continuous groove of the operating member and the locking projection, the locking projection of the wind direction plate and the operation By changing the engagement position of the member with the continuous groove, the swing angle of the wind direction plate can be reliably controlled for each set including the wind direction plate.

That is, according to the present invention, the swing angle of the wind direction plate can be manually controlled after or before remote control, so that the wind direction can be finely controlled. Moreover, since the wind direction plate and the operating member are securely locked by the large locking force between the locking projection and the continuous groove, the locking position is shifted, and the swing angle of the wind direction plate is set. It is possible to prevent deviation. Therefore, the swing angle of the wind direction plate can be reliably set by manual operation, and the driving force of a drive source such as a motor is operated through the locking portion between the locking projection and the continuous groove. Since the power can be reliably transmitted from the member to the wind direction plate, the power consumption of the drive source can be saved. Therefore, both convenience and comfort can be enhanced. For this reason, it is possible to obtain comfort that meets the detailed requirements of the user.

Further, in the present invention, since only one drive source such as a motor is required, a crank mechanism or the like for converting the rotational motion into a reciprocating motion and a control means for remotely controlling the drive source are also provided.
Since a stand is sufficient and the number of components can be reduced, the configuration can be simplified and the cost can be reduced.

[0018]

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a schematic plan view of an essential part of one embodiment of the present invention, in which a wind direction adjusting mechanism 11 of an air conditioner blows out conditioned air such as cold air or hot air. For example, a plurality of substantially rectangular plate-shaped wind direction plates 13, 13... Are erected at a horizontally elongated rectangular air outlet 12, and are arranged in parallel in a longitudinal direction of the air outlet 12 at a required pitch. Are divided into, for example, two sets of left and right L and R.

Each wind direction plate 13 is rotatably attached to the opening edge of the air outlet 12 by a pin 14 at an inner end located on the inner side of the air outlet 12 and, as shown in FIG. The lower portions of the 13 free ends are connected by a pair of left and right connecting rods 15L, 15R for each of the left and right sets L, R.

Therefore, the swing angle of each wind direction plate 13 is controlled for each set L, R via the connecting rods 15L, 15R.

Each of the wind direction plates 13 has a rectangular insertion hole 16 penetrating in the thickness direction at the upper end thereof.
A smaller operating plate 17, for example, in the form of a strip, is inserted through these insertion holes 16 so as to be reciprocally movable in the axial direction.

The operation plate 17 is provided with an insertion portion for inserting at least one insertion hole 16 of at least one of each of the left and right sets L and R of the wind direction plate 13 and a continuous groove 18 having a relatively shallow bottom on the upper surface before and after the insertion portion. Is formed with a required width. The continuous groove 18 is formed by, for example, forming a plurality of lateral grooves formed in the width direction on the upper surface of the operation plate 17 at a predetermined pitch in the longitudinal direction. On the other hand, left and right wind direction plates 13L, 13R
The locking projections 19 are integrally formed at the upper ends of the openings of the insertion holes 16, 16, respectively, and the locking projections 19 are relatively shallowly engaged with a part of the lateral groove 18.

The locking portion between the locking projection 19 and the continuous groove 18 is shown by a black circle in FIG.
7, when the wind direction plates 13L and 13R are manually swung to the left or right against the locking force between the locking projections 19 and the continuous grooves 18 by manual operation, the continuous grooves 18 After the locking projections 19 are slid up to release these locked states, the locking projections 19 can be locked at positions of other grooves in the continuous groove 18.

One end of the operation plate 17 is connected to a drive motor 20 such as a step motor via a crank mechanism or the like for converting a rotational motion into a reciprocating motion. 17 is moved by a predetermined amount in one of the left and right directions. The operation of the drive motor 20 is remotely controlled by a remote controller (not shown).

Next, the operation of this embodiment will be described. When the drive motor 20 rotates by a required angle by a remote operation such as a remote controller, the operation plate 17 moves in one of left and right directions in the axial direction via a crank mechanism or the like.

For this purpose, the left and right wind direction plates 1 having locking projections 19 to be engaged with a part of the continuous grooves 18 of the operation plate 17.
3L and 13R swing according to the amount of movement of the operation plate 17, and the swing angle is maintained.

The swing of the wind direction plates 13L and 13R is controlled by the other wind direction plates 1 via the left and right connecting rods 15L and 15R.
Are transmitted to each pair L, R to 3, 13,.
Are all swung in the same direction and at the same angle, and are held at the swing angle.

When the wind directional plates 13, 13 are swingable by hand, the wind directional plates 13L or 13R are pressed against the locking force between the locking projections 19 and the continuous grooves 18 of the operation plate 17. And manually forcibly oscillate, so that the locking projection 1
The swing angle can be manually set by sliding the groove 9 on the continuous groove 18 and appropriately changing the position of the locking groove.

The swing of the wind direction plates 13L or 13R is connected to the wind direction plates 13, 13... Through the connecting rods 15L, 15R, respectively, and swings in the same direction and at the same angle. And the swing angle is maintained.

Further, as shown in FIG.
The swing angle of L, 13R can be different for each of the left and right sets L, R.

For example, when the swing angle of the right wind direction plate 13R is 0 ° as shown by the broken line in FIG.
If the swing angle of only 3L is tilted to the left by θ _L ° by hand in advance, and then the swing angle of the left and right wind direction plates 13L, 13R is tilted to the left by θ ° by the drive motor 20,
The swing angle of the left wind direction plate 13L is θ _L + θ °, and the left set L
Can be tilted further to the left by θ _L °.

In other words, since the swing angle of the wind direction plates 13 can be set separately for the left and right sets L and R, it is possible to obtain comfort that meets the fine requirements of the user.

[0034]

As described above, according to the present invention, since the wind direction plate is swung through the drive source and the operating member driven by remote control, the swing angle of these wind direction plates can be remotely controlled.

Further, by forcibly swinging the wind direction plate by hand manually against the locking force between the locking projection and the continuous groove, the locking position between the locking projection and the continuous groove is established. Can be appropriately changed, so that the swing angle of the wind direction plate can be appropriately controlled by manual operation. In addition, since the swing angle of the wind direction plate is set by the large locking force between the locking projection and the continuous groove, it is possible to prevent the locking positions from being shifted and the swing angle of the wind direction plate from shifting. it can. For this reason, the swing angle of the wind direction plate can be reliably set by manual operation, and the driving force of the driving source such as the driving motor is operated via the locking portion between the locking projection and the continuous groove. Since the power is reliably transmitted from the member to the wind direction plate, the power consumption of the drive source can be saved.

That is, according to the present invention, the swing angle of the wind direction plate can be appropriately controlled by manual operation after or before being automatically controlled by remote control, and the wind direction can be finely and reliably adjusted. Can be.

Further, since the swing angle of the wind direction plate can be set separately for each of the right and left sets, the comfort can be enhanced. For this reason, it is possible to obtain comfort that meets the detailed requirements of the user.

Furthermore, since only one drive source is required, only one control means or the like for controlling these operations is required, so that the number of parts can be reduced, the configuration can be simplified, and the cost can be reduced.
