이하, 상기와 같이 구성된 창문형 공기조화기의 절전운전장치의 작용효과를설명한다.Hereinafter, the operation and effect of the power saving driving device of the window type air conditioner configured as described above will be described.

먼저, 본 발명의 동작설명을 위한 초기조건으로서 전원 릴레이(40)의 접점(1-1')은 접속(Normal Close) 상태이고, 팬모터 제어용 릴레이(70)의 접점(1-1')(2-2')은 접속(Normal Close) 상태 접점(3-3')은 개방(Normal Open)상태이며, 압축기 제어용 릴레이(80)의 접점(1-1')은 개방(Normal Open) 상태 접점(2-2')은 접속(Normal Close)상태이다.First, as an initial condition for explaining the operation of the present invention, the contact 1-1 'of the power relay 40 is in a normal (closed) state, and the contact 1-1' of the relay 70 for fan motor control ( 2-2 ') is the normally closed state contact (3-3') is in the normal open state, and the contact (1-1 ') of the compressor control relay 80 is the normally open state contact. (2-2 ') is in a connected (normally closed) state.

파워코드(30)를 도시되지 않은 전원콘센트에 끼우면, 외부로부터 교류전원이 파워코드(30)를 통해 기동컨덴서(90)로 인가되어 압축기(10)와 팬모터(50)의 기동전압이 생성된다.When the power cord 30 is inserted into a power outlet (not shown), AC power is applied from the outside to the starting capacitor 90 through the power cord 30 to generate starting voltages of the compressor 10 and the fan motor 50. .

이때, 설정온도를 입력한다음 풍량설정스위치(60)를 강냉(A) 또는 강냉(B)에 위치시키면, 압축기 제어용 릴레이(80)의 접점(2-2')을 통해 압축기(10)의 'R'단자로 전원이 인가되고 또한 실내온도가 설정온도보다 높을 때 온도조절기(20)의 단자(T1-T2)가 접속되어 압축기(10)의 'C'단자로 전원이 인가된다.At this time, when the set temperature is input and the air volume setting switch 60 is positioned at the strong cooling (A) or the cold cooling (B), the compressor 10 of the compressor 10 is connected through the contact 2-2 ′ of the compressor control relay 80. When power is supplied to the R 'terminal and the room temperature is higher than the set temperature, the terminals T1-T2 of the temperature controller 20 are connected to supply power to the' C 'terminal of the compressor 10.

따라서, 파워코드(30)→ 온도조절기(20)의 단자(T1-T2)→ 압축기(10)→ 압축기 제어용 릴레이(80)의 접점(2-2')→ 풍량설정스위치(60)→ 전원 릴레이(40)의 접점(1-1')→ 파워코드(30)로 연결되는 폐회로를 구성하여 압축기(10)가 운전을 시작한다.Therefore, the power cord 30 → the terminal (T1-T2) of the temperature controller 20 → the compressor 10 → the contact point (2-2 ') of the compressor control relay 80 → the air volume setting switch 60 → the power relay Compressor 10 starts operation by constructing a closed circuit connected to contact 1-1 '→ 40 of power source 40.

이와 동시에, 팬모터 제어용 릴레이(70)의 접점(1-1')을 통해 팬모터(50)의 고속('H')단자로 전원이 인가되어 파워코드(30)→ 기동컨덴서(90)→ 팬모터(50)→ 팬모터 제어용 릴레이(70)의 접점(1-1')→ 풍량설정스위치(60)→ 전원 릴레이(40)의 접점(1-1')→ 파워코드(30)로 연결되는 폐회로를 구성하여 팬모터(50)가 고속으로 회전한다.At the same time, power is applied to the high speed ('H') terminal of the fan motor 50 through the contact 1-1 'of the fan motor control relay 70 so that the power cord 30 → starting capacitor 90 → Fan motor (50) → contact (1-1 ') of fan motor control relay (70) → air volume setting switch (60) → contact (1-1') of power relay (40) → connection with power cord (30) The fan motor 50 rotates at a high speed by configuring a closed circuit.

상기 압축기(10)와 팬모터(50)의 운전에 따라 실내공기의 온도가 점차 낮아져 도 4에 도시한 바와같이, 실내온도가 설정온도에 도달하는 서모 오프(THERMO OFF)조건이 발생하면, 온도조절기(20)의 단자(T1-T3)가 접속되므로 전원 릴레이(40)에 전원이 인가되어 릴레(40)이 접점(1-1')이 개방되면서 압축기(10)가 정지한다.As the temperature of the indoor air gradually decreases as the compressor 10 and the fan motor 50 operate, as shown in FIG. 4, when a thermo-off condition occurs in which the indoor temperature reaches a set temperature, the temperature is increased. Since terminals T1-T3 of the regulator 20 are connected, power is applied to the power supply relay 40 so that the compressor 10 stops while the relay 40 opens the contact 1-1 ′.

상기 온도조절기(20)의 단자(T1-T3)가 접속되면, 팬모터 제어용 릴레이(70)에도 전원이 인가되어 릴레이(70) 접점이 (1-1')(2-2') 상태에서 (3-3') 상태로 바뀌므로 팬모터 제어용 릴레이(70)의 접점(3-3')을 통해 팬모터(50)의 저속('L')단자로 전원이 인가되어 파워코드(30)→ 기동컨덴서(90)→ 팬모터(50)→ 팬모터 제어용 릴레이(70)의 접점(3-3')→ 파워코드(30)로 연결되는 폐회로를 구성하여 팬모터(50)가 도 4에 도시한 바와같이, 저속으로 회전하여 공기조화기내의 잠열(열교환 공기)을 실내로 토출시킨다.When the terminals T1-T3 of the temperature controller 20 are connected, power is also applied to the fan motor control relay 70 so that the contact point of the relay 70 is (1-1 ') (2-2') ( 3-3 '), the power is supplied to the low speed (' L ') terminal of the fan motor 50 through the contact (3-3') of the fan motor control relay 70, the power cord 30 → The fan motor 50 is shown in FIG. 4 by constructing a closed circuit connected to the starting capacitor 90 → the fan motor 50 → the contact point 3-3 ′ of the fan motor control relay 70 → the power cord 30. As mentioned above, it rotates at low speed and discharges the latent heat (heat exchange air) in an air conditioner.

서모 오프에 따라 실내온도가 다시 상승되어 도 4에 도시한 바와같이, 설정온도보다 높아지는 서모 온(THERMO ON) 조건이 되면 온도조절기(20)의 단자(T1-T2)가 다시 접속되어 압축기(10)의 'C'단자로 전원이 인가됨과 동시에 전원 릴레이(40)에 인가되는 전원이 차단되어 전원 릴레이(40) 접점(1-1')이 접속되므로 압축기(10)가 다시 운전을 시작한다.When the indoor temperature rises again according to the thermo-off, and as shown in FIG. 4, when the thermo-on condition is higher than the set temperature, the terminals T1-T2 of the temperature controller 20 are connected again to the compressor 10. At the same time as the power is applied to the 'C' terminal of the) and the power applied to the power relay 40 is cut off and the power relay 40 contact (1-1 ') is connected, the compressor 10 starts to operate again.

상기 온도조절기(20)의 단자(T1-T2)가 다시 접속되면, 팬모터 제어용 릴레이(70)에 인가되는 전원도 차단되어 릴레이(70) 접점이 (3-3') 상태에서 (1-1')(2-2') 상태로 바뀌므로 팬모터 제어용 릴레이(70)의 접점(1-1')을 통해 팬모터(50)의 고속('H')단자로 전원이 인가되어 팬모터(50)가 도 4에 도시한 바와같이, 다시 고속으로 회전한다.When the terminals T1-T2 of the temperature controller 20 are connected again, the power applied to the fan motor control relay 70 is also cut off so that the contact point of the relay 70 is (3-3 ') (1-1). (2-2 ') state, the power is applied to the high speed (' H ') terminal of the fan motor 50 through the contact (1-1') of the fan motor control relay 70, the fan motor ( 50, it rotates again at high speed.

다음, 풍량설정스위치(60)를 약냉(A) 또는 약냉(B)에 위치시키면, 압축기 제어용 릴레이(80)의 접점(2-2')을 통해 압축기(10)의 'R'단자로 전원이 인가되고 또한 실내온도가 설정온도보다 높을 때 온도조절기(20)의 단자(T1-T2)가 접속되어 압축기(10)의 'C'단자로 전원이 인가되어 압축기(10)가 운전한다.Next, when the air volume setting switch 60 is positioned in the weak cooling (A) or the weak cooling (B), the power is supplied to the 'R' terminal of the compressor 10 through the contact (2-2 ') of the compressor control relay 80. When the indoor temperature is higher than the set temperature, the terminals T1-T2 of the temperature controller 20 are connected, and power is applied to the 'C' terminal of the compressor 10 to operate the compressor 10.

When the THERMO OFF condition is reached as described above, the fan motor 50 is changed by changing the mechanical contact. By rotating at a low speed, latent heat can be effectively discharged.

서모 오프에 따라 실내온도가 다시 상승되어 도 4에 도시한 바와같이, 서모 온(THERMO ON) 조건이 되면 온도조절기(20)의 단자(T1-T2)가 접속되어 압축기(10)가 다시 운전을 시작한다.As the thermo-off increases the room temperature again, and as shown in FIG. 4, when the thermo-on condition is reached, the terminals T1-T2 of the temperature controller 20 are connected to operate the compressor 10 again. To start.

상기 온도조절기(20)의 단자(T1-T2)가 다시 접속되면, 팬모터 제어용 릴레이(70)에 인가되는 전원도 차단되어 릴레이(70) 접점이 (3-3') 상태에서 (1-1')(2-2') 상태로 바뀌므로 팬모터 제어용 릴레이(70)의 접점(2-2')을 통해 팬모터(50)의 중속('MID')단자로 전원이 인가되어 팬모터(50)가 도 4에 도시한 바와같이, 다시 중속으로 회전한다.When the terminals T1-T2 of the temperature controller 20 are connected again, the power applied to the fan motor control relay 70 is also cut off so that the contact point of the relay 70 is (3-3 ') (1-1). (2-2 ') state, the power is applied to the medium speed (' MID ') terminal of the fan motor 50 through the contact (2-2') of the fan motor control relay 70, the fan motor ( As shown in Fig. 4, it rotates again at medium speed.
