Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner louver control device.

[0002]

2. Description of the Related Art In a domestic or commercial air conditioner, an indoor unit provided at one location in the room takes in air before adjusting the air in the room, air-conditions the air, and then discharges the air after the air conditioning. It is designed to be released indoors. In such an air conditioner, an air flow control louver is usually provided at the air outlet, and a louver control device for rotating the louver up and down is usually provided.

The operation timing of such a conventional louver is shown in FIG. In the figure, as indicated by a turning curve 50, the louver turns while reciprocating between the set upper limit UL and the set lower limit LL during the standard time ts.

[0004]

However, in the device having such a conventional structure, when the external force 30 acts during the operation to change the direction of the louver, as shown by the turning curve 50, The louver rotation range is normal UL to L
The louver must be rearranged by temporarily resetting and restarting the air conditioner to recover from this, because the abnormal air condition changes from IUL to ILL instead of L. For this reason, a troublesome and inconvenient operation such as turning off the air conditioner has been required.

The present invention has been made in order to solve such a problem, and its purpose is to immediately return to the normal direction without resetting the air conditioner even if the direction of the louver is changed by an external force acting during operation. It is to provide a control device for a louver of an air conditioner that can be restored.

[0006]

To achieve the above object, an air conditioner louver control device according to the present invention is an air conditioner louver control device having a louver that rotates by a predetermined angle. Is provided with a louver rotation control means for stopping the louver for a predetermined time when the louver is completely rotated.

[0007]

According to the present invention, when the reciprocating frame is moved downward, the stopper stops the movement of the reciprocating frame, and the timer gives the extended time when the louver is rotated upward. Keeps spinning. When the torque increases and exceeds the limit torque, the joint slips and slips.

When the louver is in a distorted position, it hits the stopper earlier than normal, and when the louver remains fully open, the sliding joint slips and spins idle. By the end of the time, the reciprocating frame has reached the bottom and in each case the louvers have been correctly realigned, so that the louvers will automatically return to their normal state.

[0009]

Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a partial cross-sectional perspective view of an air conditioner equipped with an embodiment of the present invention. Further, FIG. 2 is a side view of the auto louver mechanism of FIG.

The auto louver mechanism 1 of the air conditioner has a louver 2 which is rotated by a movement of a reciprocating frame 4 having a support pin 20B as an axis and a protruding column 20A provided at one end fitted therein.
0, a slip joint 2 which is directly connected to the motor 6 and slips and slips when a set torque is exceeded, and a stopper 14 arranged below the reciprocating frame 4 which is vertically moved by a rotational force from the motor 6 passing through the slide joint 2. The louver 20 is composed of a rotation control means 7 having a timer for giving an extended time when the louver 20 is rotated upward, and is incorporated in the air conditioner 10.

FIG. 3 shows an assembled state of the slide joint 2. One end of the slide joint 2 has a spindle 6
It is directly connected to the motor 6 by A and the other end is the spindle 3A.
Is directly connected to the gear 3. The slip joint 2 does not slip when the applied torque is less than or equal to the limit torque Trm,
The rotational force of the spindle 6A is transmitted to the spindle 3A, but slips when the applied torque exceeds the limit torque Trm, so that the rotational force of the spindle 6A is transferred to the spindle 3A.
It has a mechanism that it is not transmitted to, and is configured by a conventional technique. FIG. 4 shows the operation timing of the louver 20.

Next, the operation of the present invention will be described. The air conditioner 10 causes the air conditioned by the rotation of the crossflow fan 11 to be biased by the louver 20 and is discharged into the room as an outlet flow 13 from the outlet 12.

In the louver 20 incorporated in the air conditioner 10 as described above, the rotational force from the motor 6 is set as the set torque Trm.
After passing over the slip joint 2, the slip joint 2 is transmitted to the reciprocating frame 4 via a reversing mechanism (not shown in detail), and the reciprocating frame 4 receives this rotational force at the rack gear 4A to move upward ( It moves in the β direction) or downward (α direction).

When the reciprocating frame 4 moves up and down, the fitting hole 4
Since B moves up and down with the protruding column 20A of the louver 20 fitted, the louver 20 rotates downward or upward with the support pin 20B as an axis. Then, the reciprocating frame 4 reaches the lower side, and the tip 4C thereof is disposed below the stopper 1
When it touches 4, it stops moving. At this time, the louver 20 is at the set upper limit UL (fully open position).

When the reciprocating frame 4 moves upward and a preset standard time ts elapses, the louver 20 reverses its rotating direction upward, and the position at this time is the set lower limit LL. That is, the louver 20 has a set upper limit UL.
And the range of the angle θ between the set lower limit LL is rotated.

Since the rotation control means 7 with a timer gives the extended time te when the louver 20 is rotated upward, that is, when the reciprocating frame 4 is moved downward (direction α),
The reciprocating frame 4 reaches the lower side and contacts the stopper 14,
The motor 6 continues to rotate even if the movement is stopped. Therefore, when the torque applied to the slip joint 2 increases and eventually exceeds the limit torque, the slip joint 2 slips and slips. This slip period is tslp of the turning curve 25 in FIG.
Is.

Here, it is assumed that the louver 20 is in a distorted position. First, when the reciprocating frame 4 reaches the lower side earlier than normal due to the distorted position and comes into contact with the stopper 14 and stops, the louver 20 remains in the fully opened state and the torque applied to the sliding joint 2 increases. After a while, when the limit torque is exceeded, the slip joint 2 slips and slips.

The slipping of the sliding joint 2 continues only during the remaining extended time te, and when the reversing mechanism starts to move the reciprocating frame 4 upward in time, the louver 20 is in a normally open position. The rotation can be started in the returned state.

When the louver 20 moves to a distorted position by an external force 30 as shown by a turning curve 27 shown in the lower part of FIG. 4, the set lower limit LL is exceeded at t5 at the end of the standard time ts. It will be folded back at an angle.

In this state, when the reciprocating frame 4 moves downward and the louver 20 rotates upward in a state where the position is deviated, but the reciprocating frame 4 does not reach the lower side at the normal time t7 (point 27), the reciprocating frame 4 reaches downward until t8 when the extension time te ends (see point 28). Therefore, the louver 20 in the distorted position is correctly restored to the fully open state here. Arranged. If the extension time te is still left after this rearrangement, the torque applied to the slip joint 2 increases and eventually exceeds the limit torque, and the slip joint 2 slips and slips.

The idling of the sliding joint 2 continues only for the remaining extension time te, and eventually, when the extension time te is up, the reversing mechanism starts moving the reciprocating frame 4 upward. The rotation can be started in a state where is returned to the normal position where it is fully opened.

Next, the operation of the present invention will be described based on the flowchart of FIG. When rotating the louver 20 downward, the rotation control means 7 sets the timer to the standard time ts (step S1) and rotates the louver 20 downward (step S2). When the standard time ts has elapsed (step S3), the timer is set to the extension time te (step S4), and the louver 20 is rotated upward (step S5). When the extension time te elapses (step S
6) Then, the operation returns to step S1 to rotate the louver 20 downward again. Hereinafter, this is repeated. During the above steps S5 to S6, the auto louver mechanism 1 performs the position adjustment of the louver 20.

[0023]

As described above, the control device for the louver of the air conditioner according to the present invention is constructed as described above.
Even when the louver is displaced from the predetermined position, the louver is corrected to the correct state in the fully opened state, so that the louver can be started to rotate in the state where it is automatically returned to the normal position.

As a result, for example, even if the position of the louver is distorted due to an external force or the like, the louver can be corrected to its original normal position in one cycle of the subsequent rotation, so that the air-conditioned air can be adjusted. It is possible to return to a state where the air is blown out in the normal direction from the air outlet, so that the convection of the indoor air is effectively performed, the temperature difference in the room during cooling and heating can be reduced, and comfortable air conditioning can be realized. .
