본 발명은 에어컨의 실내팬 에러제어방법에 관한 것으로, 더욱 상세하게는 실내팬 록(LOCK) 발생시 실내팬 제어신호를 온/오프 하면서 록온 해제시켜 보도록 록해제 기능을 시도하도록 한 에어컨의 실내팬 에러제어방법에 관한 것이다.The present invention relates to a method of controlling an indoor fan error of an air conditioner, and more particularly, to an indoor fan error of an air conditioner, which attempts to release a lock on and off by turning on / off an indoor fan control signal when an indoor fan lock occurs. It relates to a control method.

일반적으로, 에어컨에서 실내팬 구동신호가 출력 중인데도 실내팬이 작동되지 않으면, 실내팬의 구동을 정지시키고 있다.In general, if the indoor fan is not being operated while the indoor fan driving signal is being output from the air conditioner, the driving of the indoor fan is stopped.

제1도는 일반적인 에어컨의 운전제어 블록도로서, 이에 도시된 바와 같이 예약 시간 설정, 온도 설정, 시작 및 정지 등 운전조작을 위한 키보드(1)와, 실내온도를 감지하기 위한 온도센서(2)와, 일반적인 운전제어 및 실내팬 에러 발생시 실내팬의 구동을 제어하는 마이컴(3)과, 예약시간 및 설정온도 등 운전상태를 표시하기 위한 표시부(4)와, 압축기(6), 실내팬(7)등 각종 부하들을 상기 마이컴(3)의 제어에 의해 구동시키기 위한 부하 구동부(5)와, 상기 실내팬(7)의 작동상태를 감지하여 상기 마이컴(3)에 인가시키는 에러감지부(8)로 구성된다.FIG. 1 is a block diagram of an operation control of a general air conditioner. As shown in FIG. 1, a keyboard 1 for driving operation such as a reservation time setting, a temperature setting, a start and a stop, a temperature sensor 2 for detecting an indoor temperature, and , A microcomputer 3 for controlling the operation of the indoor fan when general operation control and an indoor fan error occur, a display unit 4 for displaying an operation state such as a reservation time and a set temperature, a compressor 6, and an indoor fan 7 And a load driver 5 for driving various loads under the control of the microcomputer 3, and an error detecting unit 8 for sensing an operating state of the indoor fan 7 and applying the microcomputer 3 to the microcomputer 3. It is composed.

이와 같이 구성된 에어컨의 운전제어 장치는, 키보드(1)를 통해 운전시작, 운전정지 및 설정온도와 예약시간 등을 입력시키게 되면, 마이컴(3)은 운전상태를 표시부(4)를 통해 표시하면서 온도센서(2)로부터 감지된 실내온도가 설정온도에 도달하여 유지되도록 부하구동부(5)를 통해 각종 부하들의 구동을 제어하여 운전제어를 하고, 에러감지부(8)를 통해 실내팬(7)의 작동에러가 발생되면 마이컴(3)이 실내팬 및 전체 운전 정지 제어를 하게 된다.When the operation control device of the air conditioner configured as described above inputs a start of operation, a stop of operation, a set temperature, a reservation time, and the like through the keyboard 1, the microcomputer 3 displays the operation state on the display unit 4 and displays the temperature. Operation control is performed by controlling the driving of various loads through the load driving unit 5 so that the room temperature sensed by the sensor 2 reaches and maintains the set temperature, and the error detection unit 8 controls the operation of the indoor fan 7. If an operation error occurs, the microcomputer 3 controls the indoor fan and the entire operation stop.

제2도는 종래 에어컨의 실내팬 에러제어방법을 보인 제어흐름도로서, 이에 도시된 바와 같이 운전중 실내팬 구동신호를 출력하고 있는 경우에, 실내팬 록이 검출되면, 소정시간(t초)이 경과되는지를 체크하여 그 소정시간(t초)이 경과될 때까지 실내팬이 작동되지 않고 록 상태로 있으면 운전을 정지하도록 되어 있다.2 is a control flow chart illustrating an indoor fan error control method of a conventional air conditioner. When an indoor fan drive signal is output during operation as shown in FIG. 2, when an indoor fan lock is detected, a predetermined time (t seconds) has elapsed. If the indoor fan is not operated and remains in the locked state until the predetermined time (t seconds) has elapsed, the operation is stopped.

즉, 종래에는 실내팬의 일시적인 록이 상기한 소정시간(t초) 이상 지속되면 즉시 운전을 정지하여 제품을 보호하도록 하고 있다.That is, conventionally, when the temporary lock of the indoor fan lasts for more than the predetermined time (t seconds), the operation is immediately stopped to protect the product.

그러나, 이와 같은 종래 실내팬 에러시 제어방법은, 소정시간(t초) 동안만 실내팬의 록상태가 지속되면 운전을 정지하므로, 이물질의 유입으로 일시적으로 걸려 자체 해결될 수 있는 경우에도 운전이 정지되고, 이로 인해 제품의 운전율이 떨어지는 단점이 있다.However, such a conventional method for controlling an indoor fan error stops operation when the indoor fan lock state lasts only for a predetermined time (t seconds). It is stopped, and thus has a disadvantage in that the operation rate of the product is lowered.

본 발명의 목적은, 이와 같은 문제점을 감안하여 실내팬이 일시적으로 이물질에 걸려 정지된 경우 강제로 몇 차례 온/오프시켜 실내팬 에러의 해제를 시도하도록 하여 제품의 운전율을 높일 수 있도록 한 에어컨의 실내팬 에러 제어방법을 제공하기 위한 것이다.An object of the present invention, in order to increase the operating rate of the product by attempting to release the indoor fan error by forcibly turning on / off a few times when the indoor fan is temporarily caught by the foreign matter in consideration of such a problem. To provide an indoor fan error control method.

이와 같은 본 발명의 목적은, 운전중에 실내팬이 강제로 정지되는지를 감지하는 단계와, 실내팬이 정지되고 소정시간이 경과되었는지를 판단하는 단계와, 실내팬이 정지되어 소정시간이 경과된 후에 팬 일시정지 카운터를 증가시키고 소정 횟수 이상인지를 판단하는 단계와, 팬 일시정지 카운터가 상기 소정 횟수 미만인 경우에는 실내팬 제어신호를 정지(오프)시키고, 일정시간이 경과되는지를 판단하는 단계와, 실내팬 제어신호를 정지시키고 상기 일정시간이 경과되었으면 상기한 소정시간 카운트를 다시 시작하면서 실내팬 제어신호를 구동신호(온 신호)로 출력하는 단계와, 상기한 팬 일시정지 카운터 값이 소정 횟수 이상인 경우에는 실내팬 제어신호를 정지하고 운전을 정지시키는 단계를 수행하도록 함으로써, 달성되는 것으로, 이하 본 발명에 의한 실시예를 첨부된 도면을 참조해서 상세히 설명하면 다음과 같다.The object of the present invention is to detect whether the indoor fan is forcibly stopped during operation, determining whether the indoor fan is stopped and a predetermined time has elapsed, and after the predetermined time has elapsed since the indoor fan is stopped. Increasing the fan pause counter and determining whether the fan pause counter is greater than or equal to a predetermined number of times; if the fan pause counter is less than the predetermined number of times, stopping (off) the indoor fan control signal and determining whether a predetermined time has elapsed; Outputting an indoor fan control signal as a drive signal (on signal) while stopping the indoor fan control signal and starting the predetermined time count again, and the fan pause counter value is equal to or greater than a predetermined number of times. In this case, it is achieved by stopping the indoor fan control signal and stopping the operation. An embodiment by referring to the accompanying drawings in detail as follows.

제3도는 본 발명에 의한 에어컨의 실내팬 에러제어방법을 보인 제어흐름도로서, 이는 제1도의 마이컴(3)에서 부하구동부(5)를 통해 각 부하들을 구동 제어함과 아울러 실내팬(7)의 구동신호를 제어하게 된다. 이때 실내팬 구동신호를 온시키고 있는 중에 에러감지부(8)를 통해 실내팬의 작동상태를 감지하고, 실내팬(7)이 구동 신호가 온상태에서 록(LOCK)되면 본 발명에서는 제3도에 도시된 바와 같이 제어하게 된다.3 is a control flow chart illustrating an indoor fan error control method of an air conditioner according to the present invention, which controls driving of each load through the load driver 5 in the microcomputer 3 of FIG. The driving signal is controlled. In this case, when the indoor fan driving signal is turned on, the operating state of the indoor fan is sensed through the error detecting unit 8, and the indoor fan 7 is locked when the driving signal is turned on. As shown in FIG.

먼저, 실내팬 구동신호를 온시킨 운전중에 실내팬이 강제로 정지되는지를 감지하는 단계를 수행한다. 이어서, 실내팬이 정지된 뒤 그 정지시간을 카운트하여 소정시간(t1초)이 경과되었는지를 판단하는 단계를 수행한다.First, a step of detecting whether the indoor fan is forcibly stopped during the operation of turning on the indoor fan driving signal is performed. Subsequently, after the indoor fan is stopped, the stop time is counted to determine whether a predetermined time (t1 second) has elapsed.

이후, 실내편이 정지되어 소정시간(t1초)이 경과되면 팬 일시정지 카운터(Counter) 값을 1회 증가시키고, 그 카운터 값이 소정 횟수(n회) 이상인지를 판단하는 단계를 수행한다.Thereafter, when the indoor flight is stopped and a predetermined time (t1 second) has elapsed, the fan pause counter value is increased by one time, and a determination is made as to whether the counter value is a predetermined number (n times) or more.

만약, 팬 일시정지 카운터 값이 상기 소정 횟수(n회) 미만인 경우에는, 실내팬 제어신호를 정지(오프)시키고, 시간 카운트를 시작하여 일정시간(t2초)이 경과되는지를 판단하는 단계를 수행하고, 실내팬 제어신호를 정지시킨 뒤에 상기 일정시간(t2초)이 경과되었으면, 상기한 소정시간(t1초) 카운트를 다시 시작하면서 실내팬 제어신호를 구동신호(온 신호)로 출력하는 단계를 수행한다.If the fan pause counter value is less than the predetermined number (n times), the indoor fan control signal is stopped (off), and the time count is started to determine whether a predetermined time (t2 seconds) has elapsed. And after the predetermined time (t2 seconds) has elapsed after stopping the indoor fan control signal, outputting the indoor fan control signal as a drive signal (on signal) while restarting the predetermined time (t1 second) count. Perform.

한편, 상기한 팬 일시정지 카운터(Counter) 값이 소정 횟수(n회) 이상이 될 때까지 실내팬이 정지상태에 있으면, 실내팬 제어신호를 정지(오프)시키고, 운전을 정지시키는 단계를 수행하도록 한다.On the other hand, if the indoor fan is in a stopped state until the fan pause counter value reaches a predetermined number (n times) or more, the indoor fan control signal is stopped (off) and the operation is stopped. Do it.

따라서, 실내편이 강제로 정지되면, 소정시간(t1초) 동안 계속 구동신호를 온상태로 둔 뒤에 구동신호를 오프시키고, 그 오프상태로 일정시간(t2초)이 경과되면 다시 실내팬 구동신호를 온시켜 실내팬이 록상태가 되는지를 판단하며, 이와 같은 과정을 소정 횟수(n회) 동안 실시하여도 실내팬 정지가 해제되지 않으면 실내팬 구동신호를 정지시킴과 아울러 운전을 정지하게 된다. 즉, 실내편이 구동신호 온출력시 실내팬이 정지되면 소정 횟수 일정시간 간격으로 온/오프를 반복해서 실내팬 이상 상태를 강제로 해제되도록 시도하게 된다.Therefore, when the indoor flight is forcibly stopped, the driving signal is kept on for a predetermined time (t1 second), and then the driving signal is turned off, and when the predetermined time (t2 seconds) elapses in the off state, the indoor fan driving signal is again supplied. It is determined whether the indoor fan is in a locked state by turning on, and if the indoor fan stop is not released even if the above process is performed for a predetermined number (n times), the indoor fan driving signal is stopped and the operation is stopped. That is, when the indoor fan is stopped when the indoor driving signal is output, the indoor fan is repeatedly attempted to be forcibly released from the indoor fan abnormal state by a predetermined number of times.

이상에서 상세히 설명한 바와 같이 본 발명에 의하면, 일시적으로 실내팬이 걸린 경우 강제적으로 소정 횟수 온/오프를 반복해서 걸린 상태가 강제로 해제되도록 시도하므로, 제품의 운전율을 높일 수 있는 효과가 있다.As described in detail above, according to the present invention, when the indoor fan is temporarily caught, the on-off state is repeatedly forced to be repeatedly released for a predetermined number of times, thereby increasing the operation rate of the product.
