In general, an air conditioner is a device provided to create a more comfortable indoor environment for a human being installed for the purpose of air-conditioning or purifying the air with a cooler, a heater, and an air purifier.

Such an air conditioner is provided with a blower, an air-conditioning device, and an air purifying device for forcibly flowing the indoor air so as to suck the air in the room and then heat-exchange or purify and discharge the air back into the room.

In particular, recently, an air conditioner having an auto shutter capable of closing the discharge port when the air conditioner is not used as described above has been developed.

As shown in FIG. 1, the air conditioner having the auto shutter 7 has a suction port 2 for suctioning indoor air at the lower side of the case 1, and heat-exchanged or purified air at the upper side again to the indoor side. An ejection opening 3 for ejecting is formed.

Of course, the intake port 2 and the discharge port 3 is provided with grills 4 and 5 in the front and rear or left and right or up and down directions so that air can pass while protecting the inside.

An auto shutter 7 is provided at the discharge port 3 of the air conditioner. When the air conditioner is used, the auto shutter 7 is opened downward, and when the air conditioner is not used, the auto shutter ( 7) Close to prevent foreign substances, etc. from entering the discharge port (3).

The auto shutter 7 is configured to open or close the discharge port 3 while automatically sliding upward or downward by a driving device (not shown) installed inside the case 1.

Although not specifically illustrated in the drawings, the driving device includes a motor for driving the auto shutter 7 which opens and closes the discharge port 3 formed on the front panel of the case 1 of the air conditioner while being moved up and down. It consists of a plurality of rack gears and pinion gears for transmitting the power of the auto shutter (7). Since such a drive is already well known technology, its detailed description is omitted here.

As described above, the conventional auto air conditioner for the air conditioner has a problem in that the driving motor receives a load due to the weight of the auto shutter during the closing operation, and the auto shutter flows down. There was a serious problem that a defect occurred during the opening and closing operation.

The present invention has been made to solve the above problems, the input unit, the open sensor, the closing sensor, the timer, the heating and cooling unit and the control unit for controlling the drive motor of the auto shutter closing error of the air conditioner auto shutter The purpose is to provide a control method.

The present invention provides a method of controlling an auto shutter closing error of an air conditioner, comprising: inputting a stop signal by an input unit; A driving motor control step of receiving a signal from the input unit and controlling the driving motor to close the auto shutter; Determining whether the auto shutter is closed by the controller to determine whether the auto shutter is closed through an opening sensor and a closing sensor; And controlling the air conditioning function of the air conditioner to normally operate when the auto shutter is closed as a result of the determination of the controller.

If the auto shutter is not closed as a result of the determination of the controller, the controller determines whether the count time has elapsed from the timer counting the elapsed time from the time when the controller determines whether the auto shutter is closed. A setting time determining step; A predetermined time determining step of determining, by the controller, whether the timer count time exceeds the predetermined time including the preset time when the count time of the timer has passed a preset time; And stopping the operation of the air conditioner and displaying the closing error of the auto shutter when the count time of the timer exceeds a predetermined time.

The method may further include determining whether the control unit repeats the auto shutter closing step and the preset time determining step several times when the count time of the timer has not passed the preset time. And

The controller may further include displaying a closing error of the auto shutter and stopping the operation of the air conditioner when the auto shutter is determined whether the auto shutter is closed or the predetermined time determination step is repeated several times. .

The control unit may further include determining whether the auto shutter is closed when the control unit does not repeat the auto shutter closing and determining the predetermined time determination step several times. .

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the method for controlling the closing operation of the auto shutter for the air conditioner according to the present invention.

The air conditioner according to the present invention comprises an air conditioner (10) including a compressor, an evaporator and a condenser, which forms a general heat exchange cycle, an auto shutter (7) formed at an outlet of the air conditioner, and the auto shutter (7). It includes a drive motor 12 for operating up and down, and a control unit 20 for controlling the operation of the drive motor 12 and the cooling and heating unit 10.

In addition, the control unit 20 is an input unit 14 for inputting the operation and stop signal of the air conditioner, and is attached to the lower side of the discharge port of the air conditioner and grounded with the auto shutter 7, the open state of the auto shutter 7 An opening detection sensor 15 for detecting a state, a dip detection sensor 16 attached to an upper side of the discharge port of the air conditioner and grounded with the auto shutter 7 to detect a closed state of the auto shutter 7, and an auto shutter ( The timer 17 is connected to the input unit 14, the closing detection sensor 16, the opening detection sensor 15 and the timer 17 to connect the timer 17 which counts the operation time from the stopped state after the operation 7). Accordingly, the operation of the driving motor 12 for driving the auto shutter 7 of the air conditioner is controlled, and the operation of the cooling and heating unit 10 is controlled.

Specifically, the control unit 20 operates the air-conditioning function of the air-conditioning unit 10 according to the operation signal of the input unit 14, and the drive motor 12 to open the auto shutter 7 before the air-conditioning function is operated. On the contrary, in response to the stop signal, the cooling and heating function of the air-conditioning unit 10 is stopped, and the driving motor 12 is controlled so that the auto shutter 7 is closed.

In addition, the controller 20 determines whether the auto shutter 7 is completely closed by the closing detection sensor 16 and the opening detection sensor 15 when the air conditioner stops operating, and then the auto shutter 7 Is not completely closed, the elapsed time is counted by the timer 17 and when the elapsed time exceeds the set time, an error of the auto shutter 7 is displayed, and the air conditioner is Stop operation

As shown in FIG. 3, when the stop signal of the air conditioner is detected at the input unit 14 (S100), the auto shutter 7 performs the operation of closing (S200). Thereafter, the controller 20 determines whether the auto shutter 7 is completely closed through the opening detection sensor 15 and the closing detection sensor 16 (S300). If the auto shutter (7) is completely closed in the step (S300), the control unit 20 makes it possible to normally operate the air conditioning function of the air conditioner (S400).

On the other hand, if the auto shutter (7) is incompletely closed in step (S300), the control unit 20 performs step (A).

Referring to FIG. 4, when it is determined in step S300 that the auto shutter 7 is incompletely closed, the timer 17 operates to count the elapsed time from the step S300, and the controller 20 It is determined whether the count time of the timer 17 has elapsed 2 seconds (S310). If it is determined in step S310 that the count time of the timer 17 has passed 2 seconds, the controller 20 determines whether the count time of the timer 17 exceeds 30 seconds (S320). In addition, if it is determined in step S320 that the count time of the timer 17 exceeds 30 seconds, the control unit 20 displays a closing error of the auto shutter 7, and the air conditioner performs the following operation. The drive motor 12 continues to operate to stop the operation of the air conditioner so as not to overload the air conditioner (S330).

Returning to step S310 again, if it is determined in step S310 that the count time of the timer 17 has not elapsed from 2 seconds from the step S300, the control unit 20 performs steps S300 and S310. It is determined whether the process is repeated three times (S350). At this time, if it is determined that the process of the steps (S300) and (S310) is not repeated three times, the control unit 20 performs the step (S300) again, and the process of the (S300) and (S310) step 3 When it is determined that the repetition is repeated, the operation of the air conditioner is displayed in order to display the closing error of the auto shutter 7 and to keep the drive motor 12 continuously operating by overloading the air conditioner by performing the next operation. To stop (S330).

Therefore, in the state where the auto shutter 7 is not completely closed by the controller 20, the operation of the air conditioner is stopped to prevent the overload of the drive motor 12, and only when the auto shutter 7 is completely closed. In order to perform the following operation, it is possible to prevent the performance degradation of the air conditioner due to the closing failure of the auto shutter 7.

As described above, the present invention has the effect of preventing the overload of the drive motor for operating the auto shutter by solving the problem that the auto shutter is operated without being completely closed due to the auto shutter's own weight during the closing operation of the auto shutter. .

In addition, when the closing of the auto shutter occurs, the error display by the controller can easily recognize the closing of the auto shutter, thereby preventing the performance of the air conditioner.

In the above, specific preferred embodiments of the present invention have been illustrated and described. However, the present invention is not limited only to the above-described embodiments, and those skilled in the art to which the present invention pertains may vary without departing from the spirit of the technical idea of the present invention described in the claims below.
