Abstract

PURPOSE: To obtain a method of adjusting louvers of an air conditioner for arbitrarily setting starting and end points of swing of the louvers. CONSTITUTION: When a swing setting key signal is inputted to an air conditioner during the original operation of louvers thereof, the air conditioner enters a swing setting mode and moves the louvers to their initial positions to enter a starting point save mode, which initializes the position counting data of the louvers. Then, the count data of the starting and end points are saved. Thus, the louvers swing between the newly set starting and end points.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for adjusting the louvers of an air conditioner, and more particularly to a method for adjusting the louvers of an air conditioner, which allows a user to adjust the swing width of the louvers as desired.

0002

2. Description of the Related Art Generally, most of the louvers of an air conditioner are installed in the form of a grid at the upper front of the device, and conditioned air from the inside of the device is discharged through the louvers. There are two methods for adjusting the louver: a manual adjustment method and a microcomputer-based adjustment method as shown in FIG.

0003

However, the former manual adjustment method is troublesome in that the user must set the position of the louver each time the device is used. In the latter case, the louver is allowed to swing within a permissible range at an angle determined at the time of device design, and the louver is only allowed to stop at a certain position within that range. In other words, it is possible for the louver to stop at a certain position within the tolerance range, but it is not possible to swing from any solstice within the tolerance range.

[0004] Therefore, depending on the location where the air conditioner is installed or the position of the user, the swing range of the louver cannot be adjusted arbitrarily, so the actual situation is that the user's needs cannot be satisfied. Met.

[0005] A typical example of the conventional technology is JP-A-62-1.
It is announced in Publication No. 34441. According to this conventional example, when the air blowing temperature or room temperature reaches a predetermined value, the heating capacity is reduced in order to lower the rotational speed of the variable rotational speed compressor and change the airflow direction from downward concentrated blowing to downward divided blowing. In addition, when the temperature of the air outlet increases further, the rotation speed of the variable speed compressor is lowered to suppress the temperature of the air outlet while increasing the temperature from the periphery of the lower part of the living space. It is designed to provide heating.

However, this conventional example does not allow the user to operate the louver as desired to change the direction of the wind.

[0007] Accordingly, an object of the present invention is to provide a louver adjustment method that allows the user to arbitrarily and directly select the start and end points of the swing of the louver depending on the installation position of the air conditioner and the user's position. It is in.

[0008]

[Means for Solving the Problems] In order to achieve the above object, in the present invention, when a swing set key signal is input while the louver of an air conditioner is performing its original function, the louver enters the swing set mode; Send the louver to its initial position, set the start point save mode, and initialize the louver's position count data. Next, save the count data at the start point and the count data at the end point. The louver is then configured to swing between the newly set starting point and ending point.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in detail with reference to the accompanying drawings.

FIG. 1 is a schematic block diagram of a louver adjustment device applied to the present invention. This louver adjustment device includes a key matrix section 1 that sets data for the swing motion of the louver, a microcomputer 2 that receives the data set from the key matrix section 1, performs judgment control, and outputs step drive pulses, and the microcomputer 2 that outputs step drive pulses. The louver is comprised of a motor drive section 3 that receives a step drive pulse signal from the motor drive section 2 and controls the stepping motor, and a four-phase stepping motor 4 that receives a step drive signal from the motor drive section 3 and swings the louver.

In the louver adjustment device configured as described above, when a louver swing set key signal is selected and inputted from the key matrix unit 1, the microcomputer 2 receives the swing key signal and makes a control decision, and controls the swing of the louver. After the width, swing start point, and end point are stored, the motor drive section 3 that drives the stepping motor 4 is caused to output the stored drive pulses. The drive pulses output at this time are as shown in FIG.
Step pulses divided into four stages are output from ▲bar▼ and B▲bar▼.

[0012] Accordingly, the motor drive unit 3 receives the step pulse and supplies a drive signal to the stepping motor 4, and the microcomputer 2 stores the swing width, swing start point, and swing end point of the louver. Swing motion will be performed within the range of the state.

FIGS. 3 to 6 are flowcharts showing the process of adjusting the swing width of the louver according to the present invention. Here, FIG. 4 is a flowchart that is a continuation of FIG. 3, and symbols a and b in FIG. 3 correspond to symbols a and b in FIG. 4, respectively.

First, in FIGS. 3 and 4, when power is supplied to the device, a louver servo routine (LOUVER SERVO ROUTINE) is performed at step 100.
and begin to perform its original functions. Next, in step 101, it is determined whether a swing set key signal is input from the key matrix unit 1. If the swing set key signal is not input at this time, the process moves to step 102 to determine whether the swing setting mode has been reset, and if it has been reset, the process moves to step 100 to perform the original function. If it has not been reset, the process moves to step 109 (FIG. 4) in which it is determined whether the swing starting point save mode is in effect.

On the other hand, if the swing set key signal is input in step 101, the process moves to step 103 to reset the swing set key data. Thereafter, the process proceeds to step 104, where it is determined whether the swing setting mode is the reset mode, and if it is not the reset mode, the process proceeds to step 109 (FIG. 4), where it is determined whether the swing setting mode is the swing start point save mode.

Further, in step 104, if the louver swing setting mode is the reset mode, step 10
Step 5 initializes the louver position, sets a swing start point save mode in step 106, initializes the louver position count data in step 107, and jumps to the louver operation servo routine in step 108.

As shown in FIG. 5, in the louver operation servo routine, a one-step pulse is output (step 11).
4) After driving the motor and incrementing the louver count data by 1 in the next step (step 115), return to step 100.

On the other hand, in the steps 102 and 104,
If the answer is "no" (that is, if the swing setting mode has not been reset), the swing range of the louver is set. To explain this process with reference to FIG. 4, it is determined in step 109 whether the mode is the start point save mode, and if it is "possible", the process moves to step 112 to save the start point count data. At this time, if the position of the louver is changed, the count data will also be changed, so the data at the starting point is saved as the current count data while checking the current position of the louver using the count data. In step 113, an end point save mode is set, and the process moves to step 100.

On the other hand, if the start point save mode is "no" in step 109, the end point count data is saved in step 110, the swing setting mode is reset in step 111, and then the process moves to step 100.

The louver servo routine performed in step 100, in which the start and end points of the louver operation are set as described above, will now be described with reference to FIG.

When the jump is made to the louver servo routine at step 100, it is determined whether the louver drive mode is set (step 116), and if the result is "no", the process returns; if the result is "possible", the process returns. Moving to step 117,
Output a step pulse to drive the louver, step 118
The louver position count data is increased by a pulse per step.

While driving while increasing the start count data as described above, it is determined in step 119 whether the start count data is the same as the position count data. At this time, if the start count data and position count data are the same, the stepping motor is continued to be driven, and then the process returns to the point where it jumped to the louver servo routine.

In step 119, if the start count data and the position count data are not the same, step 12
1 to determine whether the position count data is greater than the start count data and smaller than the end point count data. At this time, if the position count data is greater than the end point count data, the process moves to step 122, turns off the stepping motor, and returns. On the other hand, if the position count data is smaller than the end count data, step 1
20, the stepping motor is continuously driven.

That is, while the position count data is within the data range of the starting point and the ending point, the operation of the louver is controlled within the range of the starting point and the ending point while continuously rotating forward and backward.
