The present invention provides an apparatus for detecting the position of the auto shutter installed to open and close the discharge port of the front panel, and an air conditioner having a position control type auto shutter capable of controlling the speed of the driving motor by using the same. It relates to a control method.

In general, an air conditioner is a type of air conditioner that cools or cools indoor air appropriately, and cools and circulates and purifies air for the purpose of air conditioning.

Such an air conditioner can be divided into an integral type in which a component constituting a cooling cycle is provided in one unit and a separate type in which two units are separately provided. It can be divided into a wall type and a stand type for installing the indoor unit on the floor, and a wall type for installing the indoor unit on the wall.

The stand type air conditioner is a separate molar type mounted on the floor of the room to cool the indoor space, and is a kind of air conditioner that is widely used recently.

The separate air conditioner liquefies the refrigerant gas compressed in the compressor by exchanging heat with outdoor air in a condenser (outdoor heat exchanger), and then heat-exchanges the refrigerant passing through the expansion valve with indoor air in an evaporator (indoor heat exchanger). The room is cooled by using the heat of vaporization.

The indoor unit 10 of the separate type air conditioner includes a main body 11 having an inlet 12 at a lower front face thereof and an outlet 13 provided at an upper front face thereof, and an inclined obliquely installed at an upper upper side of the main body 11. It is composed of an evaporator (14) for cooling the blower (blower, 20) provided in the lower side of the evaporator (14) forcibly sucked indoor air and discharged to the evaporator (14) side.

In recent years, an auto shutter is installed on the front panel of the discharge port formed in the air conditioner to prevent foreign matter from flowing through the discharge port of the air conditioner main body.

Or less, on the basis of the accompanying drawings to illustrate the configuration of the prior invention.

1 is a view showing an air conditioner having an air outlet opening and closing device according to the prior art.

In addition, if the user manually drives the auto shutter 14 while the auto shutter 14 is sliding, the position of the auto shutter 14 may not be known exactly how the opening or closing of the discharge port 13 is opened, and thus the discharge port 13 is closed. Even if the opening is completed or the discharge port 13 is closed, there is a problem that the drive motor for driving the auto shutter 14 is continuously operated.

On the contrary, since the exact position is not known, the auto shutter 14 may fail to open and close the outlet 13.

In addition, the position of the auto shutter 14 can not be opened and closed, so it can only be opened and closed only by a predetermined time, so that it is impossible to be driven at a high speed at the time of initial opening or initial closing, so that the speed can be controlled when the auto shutter 14 is opened and closed. No problem occurs.

Accordingly, the present invention has been made to solve the above problems, it is to detect the opening and closing position of the auto shutter that is constantly opened and closed at low speed, and to control to open and close the remaining portion of the auto shutter that is not opened or closed according to the position It is also possible to provide an auto shutter of the air conditioner discharge opening which can detect the opening and closing position which can be varied in speed so as to be driven at high speed and low speed operation in a certain section in which the auto shutter is opened and closed according to the open / close position detection value of the auto shutter. There is this.

2 to 5, the auto shutter 110 to block or open the discharge port 13 in the discharge port 13 for discharging the cold air formed in the front of the main body 11 of the air conditioner 10. It is most preferably formed to slide up and down on the front of the main body 11 most preferably.

In addition, it is formed between the rear of the auto shutter 110 and the discharge port 13 so as to slide the auto shutter 110 is formed of a drive motor 16 and a drive device 15 for driving the auto shutter 110. .

Here, the driving device 15 is not shown in detail, and various devices are used in the prior art, and the detailed description of the driving device 15 is omitted because it is mentioned in the related art.

The detection unit 120 is formed on the rear surface of the auto shutter 110 by dividing the position of the auto shutter 110 at regular intervals.

Here, the detected part 120 is spaced at a predetermined interval on one side of the rear surface of the auto shutter 110 in a direction in which the discharge port 13 is opened and closed by the driving motor 16, and generally in a vertical direction of the discharge port 13. Is formed.

The detected part 120 is most preferably installed such that a plurality of protrusions and protrusions 121 and the grooves 122 between the protrusions 121 and the protrusions 121 are constantly arranged.

The detection unit 130 is installed below the discharge port 13 at the distal side of the auto shutter 110 when the auto shutter 110 blocks the discharge port 13, and thus the yaw of the detected unit 120 is detected. It is recognized that the auto shutter 120 slides according to the shape of the groove 121 or the uneven portion.

The detector 130 generally includes a transmitter 131 and a receiver 132. The detector 130 is installed at a predetermined length from both sides of the detector 120 to detect the detector 130 between the transmitter 131 and the receiver 132. 120 slides up and down.

When the detected part 120 passes between the transmitter 131 and the receiver 132, the unevenness 121 disconnects reception of the transmitter 131 and the receiver 132, and the groove 122 transmits the transmitter 131. In the receiver 132 signal is to be recognized.

Therefore, the detection unit 130 is most preferably provided with a photo interrupt sensor that can transmit and receive the signal value according to the shape of the groove 122 or the concave-convex 121 of the detected unit 120.

Although the detection unit 120 has been described as the concave-convex 121 and the concave groove 122, the reflection plate (not shown), such as a mirror, is installed to be spaced apart by a predetermined length so that the sensor of the detection unit 120 is recognized by the reflecting plate. Since it can be installed to make it possible, those skilled in the art will naturally be able to implement a modification.

The controller 140 controls the transmitter 131 and the receiver 132 of the detector 140 through the grooves 122 and the grooves 122 through the signal values (number) detected while the grooves 122 and the protrusions 121 are slid. It detects whether it passes or how many unevenness 121 passes, and controls the driving motor 16 to control the driving speed of the auto shutter 110 at a normal speed or to drive at a slightly higher speed. do.

When the outlet 13 is opened and closed by driving the auto shutter 110 in detail, FIG. 6 illustrates a control method of an air conditioner having a position controllable auto shutter according to the present invention. One flow chart.

If indoor air is below a set temperature or a forced operation by a user, power is applied to the air conditioner 10 (S100).

As such, when power is applied to the air conditioner 10, the auto shutter 110 is slid and driven at the reference drive set speed set to initially open the drive motor 16 (S200).

When the auto shutter 110 is slid, the grooves 122 and the convex and convexities 121 of the to-be-detected part 120 slide between the transmitter 131 and the receiver 132 of the detector 130 in the up and down direction. The control unit 140 detects the position of the auto shutter 110 through detection and blocking of signals generated by the transmitter 131 and the receiver 132.

Here, when the auto shutter 110 is slid to open or shut off the discharge port 13, the first set number of sets the initial opening speed section is determined so that the auto shutter 110 is opened at a normal driving speed. (S300).

That is, the detection unit 120 detects the detection unit 130 at the position of the first set number which is the initial opening speed section in which the position of the auto shutter 110 input from the detection unit 130 to the control unit 140 is set. It will be judged if it is recognized.

When the position of the auto shutter 110 input from the detection unit 130 to the control unit 140 is the first set number which is the end point of the initial opening speed section, the control unit 140 controls the driving motor ( By increasing the speed of 16) to speed up the opening or blocking of the discharge port 13 (S400).

While the auto shutter 110 slides at an increased speed by controlling the driving motor 16, the detection unit 130 receives the position through the detection unit 120.

The control unit 140 is set to a terminal opening speed section of the auto shutter 110 so that the auto shutter 110 to stop all of the discharge port 13 or to stop a certain period, that is, the speed increase gradually before all open. 2 to determine the set number of positions (S500).

That is, whether the detected part 120 is recognized in the detection part at a position of the second set number which is the terminal opening speed section in which the position of the auto shutter 110 inputted from the detection part 130 to the control part 140 is set. Will be judged.

By the output value of the signal indicating that the auto shutter 110 has reached the terminal opening speed section, the controller 140 increases the speed of the drive motor 16 such that the drive speed of the auto shutter 110 becomes a set drive speed. Control to reduce (S600).

For example, 20 unevenness 121 is formed on the rear surface of the auto shutter 110, and 20 unevenness 122 is formed between the unevenness 121 and the unevenness 121. The number 4 grooves 121 or the number 4 grooves 122 are set, and the second set number 16 grooves 12 or the number 16 grooves 121 are set.

Here, when power is applied to the air conditioner 10, when the auto shutter 110 is slid, the position to be detected is input while the detection unit 120 passes through the detection unit 130.

That is, the output value of the number of detected units 120 passing through the number of the signal being blocked or passed by the transmitter 131 and the receiver 132 of the detector 130 is input to the controller 140. .

Until the number of the detected units 120 input to the detector 130 is four, the drive motor 16 controls to open and close the auto shutter 110 at a constant speed.

When the number of detected units 120 input to the detector 130 is four, the controller 140 increases the speed of the driving motor 16 to increase the speed at which the auto shutter 110 is opened and closed.

As such, when the opening / closing speed of the auto shutter 110 is increased rapidly and the values of the detected parts 120 detected by the detection unit 130 are 16, the controller 140 controls the speed to be opened and closed at a constant speed. Will be.

As described above, it is possible to vary the initial speed at which the auto shutter is opened and the terminal speed at which the auto shutter is opened, the terminal speed at which the auto shutter is opened, and the position between the initial position and the terminal position by accurately detecting the opening and closing positions of the auto shutter through the detection unit and the detected unit. The effect is to be made possible.

In addition, the position of the auto shutter can be slid, and even if the user manually operates the auto shutter, the position of the auto shutter can be recognized accurately, so that the effect of precisely controlling the opening and closing of the auto shutter can occur. do.

In addition, since the position at which the auto shutter is opened can be adjusted, the effect of controlling the discharge area of the air conditioner also occurs.
