그리고, 상기 제어수단(104)은 상기 전원수단(100)으로부터 출력되는 직류전압을 인가받아 공기조화기를 초기화시킴은 물론, 운전조작수단(102)에 의해 입력된 운전선택신호 및 운전시작/운전정지신호에 따라 공기조화기의 전체적인 동작을 제어하는 마이크로컴퓨터로서, 상기 실내온도감지수단(106)과 개방단계감지수단(126) 및 속도감지수단(128)의 출력을 받아 상하풍향조절날개 및 토출구 주변에 이슬이 맺핼 조건이 되면 토출 풍량을 한 단계 증가시켜서 냉방운전을 수행하도록 공기조화기를 제어한다.In addition, the control unit 104 receives the DC voltage output from the power supply unit 100 to initialize the air conditioner, as well as the operation selection signal and the operation start / stop operation input by the operation operation unit 102. A microcomputer that controls the overall operation of the air conditioner according to a signal, and receives the output of the indoor temperature sensing means 106, the open stage sensing means 126, and the speed sensing means 128, and the up-and-down wind direction control blades and the outlet openings. When the dew condensation conditions, the air conditioner is controlled to perform a cooling operation by increasing the discharge air flow by one step.

즉, 상기 제어수단(104)은, 실내온도가 소정온도 이하인 상태에서 공기조하기가 냉방운전시 실내팬모터(18)의 회전속도가 소정속도 이하임과 동시에 상하풍향조절날개(14-1)의 개방단계가 토출구(13)가 최소로 개방된 상태에 해당하는 단계인 경우에 이슬 맺힘 조건으로 판단하여 토출 풍량을 한 단계 증가시켜서 냉방운전을 수행한다.That is, the control means 104, the air conditioning in the air condition at room temperature or less than the predetermined temperature during the cooling operation, the rotational speed of the indoor fan motor 18 at the same time or less and at the same time up and down wind direction control wing 14-1 When the opening step is a step corresponding to a state in which the discharge port 13 is opened to the minimum, it is determined that the dew condensation condition is performed to increase the discharge air volume by one step to perform the cooling operation.

상기와 같이 구성된 공기조화기의 운전제어장치 및 그 운전제어방법의 작용 및 효과를 설명한다.The operation and effect of the operation control device and the operation control method of the air conditioner configured as described above will be described.

도 4는 본 발명에 따른 공기조화기의 운전제어방법의 순서도로서, 도 4에서 S는 단계(step)를 표시한다.4 is a flowchart of an operation control method of an air conditioner according to the present invention, in which S denotes a step.

먼저, 공기조화기에 전원이 인가되면, 전원수단(100)에서는 도시되지 않은 교류전원단으로부터 공급되는 상용교류전압을 상기 공기조화기의 구동에 필요한 소정의 직류전압으로 변환하여 각 구동회로 및 제어수단(104)에 출력한다.First, when power is applied to the air conditioner, the power supply means 100 converts a commercial AC voltage supplied from an AC power terminal (not shown) into a predetermined DC voltage required for driving the air conditioner, thereby driving each circuit and control means ( Output to 104).

상기와 같이 전원수단(100)으로부터 출력되는 직류전압이 제어수단(104)으로 인가되면 상기 제어수단(104)은 공기조화기를 초기화시킨다.(S1)When the DC voltage output from the power supply means 100 is applied to the control means 104 as described above, the control means 104 initializes the air conditioner (S1).

그리고, 사용자가 운전조작수단(102)을 조작하여 운전시작신호를 제어수단(104)으로 입력하고, 이어서 공기조화기의 운전 조건(운전모드, 설정온도, 설정풍량등)을 설정하기 위해 운전 선택 신호를 제어수단(104)으로 입력한다.(S2, S3)Then, the user operates the operation operation means 102 to input an operation start signal to the control means 104, and then selects an operation to set an operation condition (operation mode, set temperature, set air volume, etc.) of the air conditioner. The signal is input to the control means 104. (S2, S3)

즉, 운전조작수단(102)으로부터 운전시작신호가 입력되었는지를 판별하여, 운전시작신호가 입력되지 않은 경우에는 공기조화기를 운전대기상태로 유지하는 것이다.That is, it is determined whether the operation start signal is input from the operation operation means 102, and when the operation start signal is not input, the air conditioner is kept in the operation standby state.

그리고, 운전조작수단(102)으로부터 운전시작신호가 입력된 상태에서 사용자가 운전조작수단(102)을 조작하여 운전 조건을 설정하기 위해 운전 선택 신호를 제어수단(104)으로 입력하여 공기조화기의 운전 조건을 설정한다.Then, when the operation start signal is input from the operation operation means 102, the user inputs an operation selection signal to the control means 104 to operate the operation operation means 102 to set the operation conditions of the air conditioner. Set the operating conditions.

이어서, 제어수단(104)은 상기 운전조작수단(102)으로부터 입력된 운전 조건이 냉방운전인가를 판별하여, 냉방운전이 아닌 경우에는 설정된 운전 조건에 따라 공기조화기를 운전한다.(S4, S5)Subsequently, the control means 104 determines whether the operation condition inputted from the driving operation means 102 is a cooling operation, and if it is not the cooling operation, operates the air conditioner according to the set operating condition. (S4, S5)

그리고, 상기 단계(S4)의 판별 결과, 냉방운전인 경우에 상기 제어수단(104)은 정상적인 냉방운전을 수행하도록 공기조화기를 제어하고, 이어서 냉방운전이 해제되었는가를 판단하여 해제되었으면 종료한다.(S6, S7)As a result of the determination in step S4, in the case of the cooling operation, the control means 104 controls the air conditioner to perform the normal cooling operation, and then determines whether the cooling operation is released and ends if it is released. S6, S7)

한편, 상기 단계(S7)의 판별 결과, 냉방운전이 해제되지 않았으면 상기 제어수단(104)은 정상적인 냉방운전을 수행하면서 실내온도감지수단(106)의 출력을 받아 실내온도가 소정온도(25℃) 이하인가를 판단하여 소정온도(25℃) 이하가 아니면 정상적인 냉방운전을 수행하도록 공기조화기를 제어한다.(S8)On the other hand, if the cooling operation is not released as a result of the determination of the step (S7), the control means 104 receives the output of the room temperature sensing means 106 while performing a normal cooling operation, the room temperature is a predetermined temperature (25 ℃) If it is not less than the predetermined temperature (25 ℃) and controls the air conditioner to perform the normal cooling operation (S8).

그리고, 실내온도가 소정온도(25℃) 이하인 경우에 상기 제어수단(104)은 속도감지수단(128)의 출력을 받아 실내팬모터(18)의 회전속도가 소정속도(800RPM) 이하인가를 판단하여 소정속도(800RPM) 이하가 아니면 정상적인 냉방운전을 수행하도록 공기조화기를 제어한다.(S9)When the room temperature is equal to or lower than a predetermined temperature (25 ° C.), the control means 104 receives the output of the speed detecting means 128 to determine whether the rotational speed of the indoor fan motor 18 is equal to or less than the predetermined speed (800 RPM). By controlling the air conditioner to perform a normal cooling operation if it is not less than the predetermined speed (800 RPM).

그리고, 실내팬모터(18)의 회전속도가 소정속도(800RPM) 이하인 경우에 상기 제어수단(104)은 상기 개방단계감지수단(126)의 출력을 받아 상하풍향조절날개(14-1)의 개방단계가 토출구(13)가 최소로 개방된 상태에 해당하는 제5단계 이상인가를 판단하여 제5단계 이상이 아니면 정상적인 냉방운전을 수행하도록 공기조화기를 제어한다.(S10)Then, when the rotational speed of the indoor fan motor 18 is less than the predetermined speed (800 RPM), the control means 104 receives the output of the opening step detection means 126 to open the up and down wind direction adjustment blade (14-1). It is determined whether the step is the fifth step or more corresponding to the state in which the discharge port 13 is opened to the minimum, and if it is not the fifth step or more, the air conditioner is controlled to perform normal cooling operation.

반면에, 상기 상하풍향조절날개(14-1)의 개방단계가 제5단계 이상인 경우에는 상기 제어수단(104)은 실내팬구동수단(122)을 제어하여 상기 실내팬모터(18)의 회전속도를 한 단계 증가시킨 상태로 냉방운전을 수행한다.On the other hand, when the opening step of the up-and-down wind direction adjustment blade 14-1 is greater than or equal to the fifth step, the control means 104 controls the indoor fan driving means 122 to rotate the speed of the indoor fan motor 18. Cooling operation is performed with one step increased.

즉, 실내온도가 소정온도(25℃) 이하인 상태에서 냉방운전시 실내팬모터(18)의 회전속도가 소정속도(800RPM) 이하임과 동시에 상하풍향조절날개(14-1)의 개방단계가 토출구(13)가 최소로 개방된 상태에 해당하는 제5단계 이상인 경우에 상기 상하풍향조절날개(14-1) 및 토출구(13) 주변에 이슬 맺힐 조건으로 판단하여 풍량을 한 단계 증가시켜 실내팬모터(18)를 구동시킴으로써, 이슬이 맺히는 것을 방지하는 것이다.That is, during the cooling operation under the condition that the indoor temperature is less than the predetermined temperature (25 ° C.), the rotation speed of the indoor fan motor 18 is equal to or less than the predetermined speed (800 RPM), and the opening step of the up-and-down wind direction adjusting wing 14-1 is discharged. In the case where (13) is the fifth step or more corresponding to the minimum open state, it is determined that dew is formed around the upper and lower wind direction adjusting blades 14-1 and the discharge port 13, and the air volume is increased by one step to increase the indoor fan motor. By driving (18), dew is prevented from forming.

이상에서 살펴본 바와 같이 본 발명에 따르면, 냉방운전시 상하풍향조절날개 및 토출구 주변에 이슬이 맺히는 조건이 되면 풍량을 한 단계 증가시켜 상기 상하풍향조절날개 및 토출구 주변에 이슬이 맺히는 현상을 방지할 수 있는 효과가 있다.According to the present invention as described above, if the dew condensation around the up and down wind direction control wing and the discharge port during the cooling operation is increased by one step to prevent the dew condensation around the up and down wind direction control wing and the discharge port.
