Description

에어컨용 필터 이물질 제거방법(A METHOD FOR REMOVING DUST ON THE FILTER OF AIR-CONDITIONER)A METHOD FOR REMOVING DUST ON THE FILTER OF AIR-CONDITIONER

본 발명은 에어컨 제어방법에 관한 것으로서, 더욱 상세하게는 에어컨의 실내기에 설치되는 증발기 및 필터에 먼지 등의 이물질 부착되어 모터의 회전수가 증가되고, 토출풍속이 감소되므로서 발생되는 소비전력 증가와 냉방성능 저하를 동시에 방지할 수 있도록 한 에어컨용 필터 이물질 제거방법에 관한 것이다.The present invention relates to a method for controlling an air conditioner, and more particularly, foreign matters such as dust are attached to an evaporator and a filter installed in an indoor unit of an air conditioner, thereby increasing the rotation speed of the motor and reducing the discharge wind speed. The present invention relates to a method for removing foreign matter from a filter for an air conditioner to prevent performance degradation.

일반적으로 에어컨은 실내기와 실외기가 일체로 형성된 창문형 에어컨과, 별도로 분리되는 분리형 에어컨 및 패키지형 에어컨으로 크게 구분되어 지고 있다.Generally, air conditioners are classified into window type air conditioners in which indoor units and outdoor units are integrally formed, and separate type air conditioners and package type air conditioners.

한편, 상기 분리형 에어컨은 실내기와 실외기로 크게 이루어지며, 실내기로는 열을 흡수하여 실내에 냉풍을 공급하는 증발기가 실외기와 연결되도록 설치되고, 실외기로는 냉매를 압축하는 압축기와 방출열을 외부로 내보내는 응축기와 이 응축기로 부터 나오는 냉매의 압력을 감압시켜 실내기의 증발기로 보내주는 팽창밸브가 설치되어 있다.On the other hand, the separate air conditioner is composed of a large indoor unit and outdoor unit, the indoor unit is installed so that the evaporator that absorbs heat to supply the cold air to the indoor unit is installed, the outdoor unit to the compressor and discharge heat to compress the refrigerant to the outside An expansion valve is installed to reduce the pressure of the condenser and the refrigerant from the condenser and send it to the evaporator of the indoor unit.

따라서, 상기 에어컨을 통한 냉방운전시는 압축기가 냉매를 압축하여 포화압력 까지 냉매가스의 압력 및 온도를 상승시켜 주면 응축기가 물이나 공기를 이용하여 고온.고압의 냉매가스가 갖고 있는 열을 흡수하여 냉매가스를 응축.액화시키게 된다.Therefore, during the cooling operation through the air conditioner, if the compressor compresses the refrigerant to increase the pressure and temperature of the refrigerant gas to the saturation pressure, the condenser absorbs heat of the refrigerant gas of high temperature and high pressure using water or air. The refrigerant gas is condensed and liquefied.

이와 같이 응축.액화된 냉매가스는 팽창밸브의 교축작용에 의해 온도와 압력이 낮아지고, 이 냉매가스가 증발기에서 증발하면서 실내공기를 열교환시켜주어 실내온도를 쾌적하게 유지시키게 되는 것이다.In this way, the condensed and liquefied refrigerant gas has a low temperature and pressure due to the throttling action of the expansion valve, and the refrigerant gas evaporates in the evaporator to heat the indoor air to maintain a comfortable indoor temperature.

도 3은 상기와 같은 역할을 수 행하는 에어컨중 분리형 에어컨의 실내기를 설명하기 위한 도면으로서, 에어컨은 크게 실내에 냉기를 공급하는 실내기(10)와 냉매를 압축하고, 방출열을 외부로 내보내는 실외기(미도시됨)로 구성되어 진다.3 is a view for explaining the indoor unit of the separate air conditioner of the air conditioner to perform the above role, the air conditioner is a large outdoor unit for compressing the indoor unit 10 and the refrigerant supplying cold air to the room, and the discharge heat to the outside ( Not shown).

상기 실내기(10)의 전면으로 실내의 공기를 흡입하기 위한 공기흡입구(11)가 형성된 전면판넬(12)이 형성되어 있으며, 공기흡입구(11) 내측으로는 먼지 및 이물질의 흡입을 방지하는 필터(13)가 설치되며, 내측으로는 흡입공기를 열교환시키는 증발기(20)와 실내온도를 검출하는 온도센서(14)가 장착되어 있다.The front panel 12 is formed with an air inlet 11 for sucking the air in the room to the front of the indoor unit 10, the filter for preventing the intake of dust and foreign matter inside the air inlet (11) 13), the inside is equipped with an evaporator 20 for exchanging the suction air and a temperature sensor 14 for detecting the room temperature.

또한, 실내기(10) 전면 하측으로 실내기(10)내에서 냉각된 공기를 실내로 배출하는 냉기배출구(15)가 형성되고, 일측으로 리모콘을 통해 송신되는 신호를 수신하기 위한 리모콘수신부(16)와 리모콘 수신에 따른 운전상태를 표시하는 운전상태 표시램프(17)가 구성되어 있다.In addition, a cold air outlet 15 for discharging the air cooled in the indoor unit 10 to the inside of the front of the indoor unit 10, the remote control receiving unit 16 for receiving a signal transmitted through the remote control to one side; An operation state display lamp 17 for displaying the operation state in accordance with the remote control reception is configured.

따라서, 사용자가 에어컨을 운전하고자 하는 경우 상기 리모콘의 운전스위치에 따른 신호를 실내기(10)의 리모콘수신부(16)로 송신하게 되고, 리모콘수신부(16)는 이 운전신호를 수신 제어부로 출력하게 되어 에어컨의 정상운전이 실시되며, 운전상태 표시램프(17)가 점등되어 사용자는 에어컨의 정상운전 상태임을 인식할 수 있는 것이다.Therefore, when the user intends to operate the air conditioner, a signal corresponding to the operation switch of the remote controller is transmitted to the remote controller receiver 16 of the indoor unit 10, and the remote controller receiver 16 outputs the operation signal to the reception controller. Normal operation of the air conditioner is performed, and the operation state display lamp 17 is turned on so that the user can recognize that the normal operation state of the air conditioner.

상기와 같이 에어컨을 사용하다 보면 필터(13) 및 증발기(20)에 흡입공기중에 섞인 먼지등의 이물질이 부착되어 진다. 따라서 사용자는 일정기간을 두고 정기적으로 필터(13)나 증발기(20)에 부착된 이물질을 제거하여 원할한 냉풍토출 및 실내공기의 오염을 예방하게 된다.When the air conditioner is used as described above, foreign matters such as dust mixed in the suction air are attached to the filter 13 and the evaporator 20. Therefore, the user periodically removes the foreign matter attached to the filter 13 or the evaporator 20 over a period of time to prevent the cold air discharge and contamination of indoor air.

그러나, 사용자가 정기적으로 기간을 정하여 필터 등에 부착된 이물질을 제거하기는 현실적으로 어려운 문제가 있으며, 이에 따라 필터 및 증발기에 이물질 부착이 증가되어 모터의 회전수가 증가되고, 또한 토출풍속이 감소되므로서 소비전력 증가 및 냉방성능이 저하되는 문제점이 있다.However, there is a problem that it is difficult for the user to regularly remove the foreign matter attached to the filter by setting a period of time, thereby increasing the adhesion of the foreign matter to the filter and the evaporator, thereby increasing the rotational speed of the motor and reducing the discharge wind speed. There is a problem that the power increase and cooling performance is lowered.

본 발명은 상기의 문제점을 해결하기 위한 것으로, RPM 검출센서와 풍속검출센서를 통해 증발기 및 필터에 이물질 부착상태를 판단하여 먼지제거 싸이클(cycle)을 통해 이물질을 제거하므로서, 모터의 정상적인 회전수를 유지할 수 있어 소비전력 증가를 방지하고, 또한 정상적인 토출풍속을 유지할 수 있어 냉방성능 저하를 동시에 방지할 수 있도록 한 에어컨용 필터 이물질 제거방법을 제공하는 것을 그 목적으로 한다.The present invention is to solve the above problems, by determining the foreign matter attached to the evaporator and the filter through the RPM detection sensor and the wind speed detection sensor to remove the foreign matter through the dust removal cycle (cycle), thereby reducing the normal rotational speed of the motor It is an object of the present invention to provide a method for removing foreign matter from a filter for an air conditioner which can maintain the power consumption and prevent the increase in power consumption, and also maintain the normal discharge wind speed.

도 1은 본 발명에 따른 에어컨용 필터 이물질 제거장치의 내부구성을 개략적으로 나타낸 블럭도로서, 냉방운전을 실시하기 위한 운전스위치(100)와 송풍팬 모터(150)의 RPM을 검출하는 RPM 검출센서(110)와 실내기(10)의 토출구 일측에 장착되어 냉풍의 토출풍속을 검출하는 풍속검출센서(120)와 증발기(20)의 온도를 검출하는 증발기 온도검출센서(130)가 각각 제어부(140)에 접속되어 있다.1 is a block diagram schematically showing the internal configuration of a filter foreign matter removal device for an air conditioner according to the present invention, the RPM detection sensor for detecting the RPM of the operation switch 100 and the blowing fan motor 150 for performing the cooling operation The control unit 140 includes a wind speed detection sensor 120 mounted at one side of the discharge port of the indoor unit 10 and an evaporator temperature detection sensor 130 that detects a temperature of the evaporator 20, and a temperature of the evaporator 20. Is connected to.

또한, 송풍팬(160)을 회전시키는 송풍팬 모터(150)와 냉매를 압축하는 압축기(170)가 각각 제어부(140)의 제어를 받도록 각각 접속되어 있다.In addition, the blower fan motor 150 for rotating the blower fan 160 and the compressor 170 for compressing the refrigerant are respectively connected to be controlled by the control unit 140.

다음에는 상기와 같이 구성된 본 발명에 따른 에어컨용 필터 이물질 제거방법을 도 3을 참조하여 상세히 설명한다.Next will be described in detail with reference to Figure 3 the foreign matter filter removal method for an air conditioner according to the present invention configured as described above.

도 2는 본 발명에 따른 에어컨용 필터 이물질 제거방법을 나타낸 흐름도로서, 사용자가 운전스위치(100)를 선택하면, 제어부(140)는 운전스위치(100)에서 인가되는 온신호를 통해 운전스위치(100)가 선택되었나를 판단하게 된다(101).2 is a flowchart illustrating a method for removing foreign matter from a filter for an air conditioner according to the present invention. When the user selects the operation switch 100, the controller 140 controls the operation switch 100 through an ON signal applied from the operation switch 100. In step 101, it is determined whether () is selected.

따라서, 사용자에 의해 운전스위치(100)가 선택되었으면, 제어부(140)는 에어컨의 각종기능을 제어하여 정상적인 냉방운전을 실시하며(102), 냉풍의 토출풍속을 검출하는 풍속검출센서(120)를 통해 인가되는 검출풍속이 사용자에 의해 선택되어진 풍량모드에 따른 기준풍속 보다 작은가를 판단하게 된다(103).Therefore, when the operation switch 100 is selected by the user, the control unit 140 performs normal cooling operation by controlling various functions of the air conditioner (102), the wind speed detection sensor 120 for detecting the discharge wind speed of the cold wind In operation 103, it is determined whether the detected wind speed is smaller than the reference wind speed according to the wind volume mode selected by the user.

상기 검출풍속이 사용자의 선택모드에 따른 기준풍속 보다 작으면 제어부(140)는 송풍팬 모터(150)를 제어하여 송풍팬(160)의 회전수를 최저로 유지하며(104), 증발기(20)의 온도를 검출하는 증발기 온도검출센서(130)를 통해 인가되는 증발기(20)의 온도가 0℃ 이하인가를 판단하게 된다(105).If the detected wind speed is smaller than the reference wind speed according to the user's selection mode, the controller 140 controls the blowing fan motor 150 to maintain the rotational speed of the blowing fan 160 to the minimum (104), the evaporator 20 It is determined whether the temperature of the evaporator 20 applied through the evaporator temperature detection sensor 130 for detecting a temperature of 0 ° C. or less (105).

상기 증발기(20)의 온도가 0℃ 이하이면 제어부(140)는 증발기(20)에서의 응축수의 빙결이 일어나지 않는 소정시간을 카운트하여 소정시간이 경과되었나를 판단하여(106), 상기의 카운트를 통해 소정시간이 경과되었으면, 제어부(140)는 압축기(170)의 구동을 정지시키고(107), 송풍팬 모터(150)를 제어하여 송풍팬(160)의 회전수를 최대로 하여 필터(13) 및 증발기(20)에 부착된 이물질을 제거하며(108), 증발기 온도검출센서(130)를 통해 인가되는 증발기(20)의 온도가 0℃ 이상으로 상승되는 지를 판단하게 된다(109).When the temperature of the evaporator 20 is 0 ° C. or less, the controller 140 counts a predetermined time at which the freezing of the condensate in the evaporator 20 does not occur and determines whether the predetermined time has elapsed (106). After a predetermined time has passed, the controller 140 stops driving the compressor 170 (107), and controls the blower fan motor 150 to maximize the rotation speed of the blower fan 160. And remove the foreign matter attached to the evaporator 20 (108), it is determined whether the temperature of the evaporator 20 applied through the evaporator temperature detection sensor 130 rises above 0 ℃ (109).

상기 증발기 온도검출센서(130)를 통해 인가되는 증발기(20)의 온도가 0℃ 이상으로 상승되었으면, 제어부(140)는 다시 증발기(20)에 빙결된 응축수가 녹는 소정시간을 카운트하여 소정시간이 경과되었으면(110), 제어부(140)는 압축기(170)를 구동하며 송풍팬 모터(150)를 제어하여 송풍팬(160)을 사용자에 의해 선택된 풍량모드에 따라 정상회전시켜주므로서, 에어컨의 정상적인 냉방운전을 실시하게 된다(111 내지 113).When the temperature of the evaporator 20 applied through the evaporator temperature detection sensor 130 has risen to 0 ° C. or more, the controller 140 again counts a predetermined time in which condensate frozen in the evaporator 20 melts, and a predetermined time is increased. When the elapsed (110), the control unit 140 drives the compressor 170 and controls the blowing fan motor 150 to rotate the blowing fan 160 in accordance with the air flow mode selected by the user, thereby ensuring normal operation of the air conditioner. Cooling operation is performed (111 to 113).

상기와 같이 본 발명은 RPM 검출센서와 풍속검출센서를 통해 증발기 및 필터에 이물질 부착상태를 판단하여 먼지제거 싸이클을 통해 이물질을 제거하므로서, 모터의 정상적인 회전수를 유지할 수 있어 소비전력 증가를 방지하고, 또한 정상적인 토출풍속을 유지할 수 있어 냉방성능 저하를 동시에 방지할 수 있다.As described above, the present invention removes the foreign matter through the dust removal cycle by determining the adhesion state of the foreign matter to the evaporator and the filter through the RPM detection sensor and the wind speed detection sensor, thereby maintaining the normal rotational speed of the motor to prevent an increase in power consumption. In addition, it is possible to maintain a normal discharge wind speed to prevent the cooling performance deterioration at the same time.
