종래의 공기조화기는 제1도 내지 제3도에 도시한 바와 같이 본체(1)의 전면에 배설되는 지지수단(3)과, 상기 지지수단(3)에 배설되어서 도시되지 않은 전원장치의 전원을 인가받아 구동되는 모터(5)와, 상기 모터(5)의 모터축부재(6)에 배설되어 상기 모터(5)에서 발생된 동력을 전달받아 정·역회전하는 피니언(7)과, 상기 피니언(7)과 기어 물림되어 상기 피니언(7)이 정·역회전됨에 따라 상·하이동되는 랙(9)과, 상기 랙(9)과 결합되어 상기 랙(9)이 상·하이동됨에 따라 토출구(11)를 개폐하는 셔터부재(13)와, 상기 본체(1)의 하측에 배설되어 실내공기를 흡입하는 다수의 흡입구멍(14a)이 형성된 흡입그릴부재(14)로 이루어져 있다.Conventional air conditioners, as shown in Figs. 1 to 3, support means 3 disposed on the front surface of the main body 1, and the power supply of a power supply device not shown and disposed on the support means 3; A pinion 7 that is applied to and driven by the motor 5 and the motor shaft member 6 of the motor 5 and receives the power generated by the motor 5 to forward and reverse rotation, and the pinion (9) is engaged with the gear rack (9) is moved up and down as the pinion (7) forward and reverse rotation, combined with the rack (9) as the rack (9) is moved up and down A shutter member 13 for opening and closing the discharge port 11 and a suction grill member 14 having a plurality of suction holes 14a disposed under the main body 1 and suctioning indoor air are formed.
상기 지지수단(3)의 상측에는 상기 흡입그릴부재(14)의 흡입구멍(14a)을 통해 흡입된 실내공기가 열교환되어 상하 및 좌우로 토출되도록 조절하는 상하풍향조절날개(15) 및 좌우풍향조절날개(17)가 배설되어 있고, 상기 지지수단(3)의 양측에는 상기 셔터부재(13)가 용이하게 이동되도록 가이드하는 가이드부재(도시하지 않음)가 배설되어 있다.The upper and lower wind direction control vanes 15 and the left and right wind direction control to adjust the indoor air sucked through the suction hole 14a of the suction grill member 14 to be discharged vertically and horizontally to the upper side of the support means (3). Wings 17 are disposed, and guide members (not shown) for guiding the shutter member 13 to be easily moved on both sides of the support means 3 are disposed.
미설명부호(19)는 본체(1)의 전면에 배설되어 내장물을 보호함과 동시에 외관을 미려하게 하는 전면판을 나타내고, 부호(21)는 공기조화기의 운전, 정지 등을 조작가능케 하는 조작부를 나타낸다.Unexplained reference numeral 19 denotes a front plate disposed on the front of the main body 1 to protect the interior and at the same time beautiful appearance, reference numeral 21 to operate, stop, etc. of the air conditioner Display the operation panel.
이와 같이 구성된 종래의 공기조화기는 운전 정지시에는 상기 토출구(11)를 폐쇄시키기 위하여 사용자가 조작부(21)의 조작조건을 선택하면, 상기 모터(5)는 전원을 인가받아 일방향으로 구동되고, 상기 모터(5)의 일측에 배설된 모터축부재(6)가 정회전됨에 따라 상기 모터축부재(6)에 배설된 피니언(7)이 정회전되고, 상기 피니언(7)에 기어 결합된 랙(9)은 상부 방향으로 이동됨과 동시에, 상기 랙(9)과 결합된 셔터부재(13)를 상부 방향으로 이동시켜 토출구(11)를 폐쇄시켜 줌으로써, 이물질 등이 본체(1)의 내측으로 투입되지 못하도록 한다.In the conventional air conditioner configured as described above, when the user selects an operation condition of the operation unit 21 to close the discharge port 11 when the operation is stopped, the motor 5 is driven in one direction by receiving power. As the motor shaft member 6 disposed on one side of the motor 5 is rotated forward, the pinion 7 disposed on the motor shaft member 6 is rotated forward, and the rack is gear-coupled to the pinion 7. 9) is moved upward and at the same time by moving the shutter member 13 coupled to the rack 9 in the upper direction to close the discharge port 11, foreign matters, etc. are not introduced into the main body (1). Don't let that happen.

The suction port blocking means 63 is disposed on one side, and the driving means 50 is disposed on one side of the support means 51 to open and close the discharge port blocking means 57 and the suction port blocking means 63 interlocked. On the suction port 65 side, a suction grill means 64 is provided which enlarges the through hole 64a to increase the suction amount of air.
상기 구동수단(50)은 동력을 발생시키도록 지지수단(51)의 일측에 배설된 구동모터(52)과, 상기 구동모터(52)의 동력을 전달받아 회전되도록 상기 구동모터(52)의 축부재(52a)에 결합된 피니언(53)과, 상기 피니언(53)의 회전력을 전달받아 직선운동됨에 따라 토출구차단수단(57)을 개폐시키도록 상기 피니언(53)의 일측에 기어물림된 제1랙(55)과, 상기 토출구차단수단(57)의 개폐시에 연동되어 흡입구차단수단(63)이 개폐되도록 상기 피니언(53)의 타측에 기어 물림된 제2랙(59)으로 이루어져 있다.The drive means 50 is a drive motor 52 disposed on one side of the support means 51 to generate power, and the shaft of the drive motor 52 to be rotated by receiving the power of the drive motor 52. The first pinion 53 geared to one side of the pinion 53 to open and close the discharge port blocking means 57 as the pinion 53 coupled to the member 52a and the linear force received by the rotational force of the pinion 53 are linearly moved. The rack 55 and the second rack 59 geared to the other side of the pinion 53 so as to interlock at the opening and closing of the discharge port blocking means 57 to open and close the suction port blocking means 63.

다음은 본 고안에 의한 공기조화기용 흡입구 및 토출구의 연동개폐장치에 대한 작용 및 효과에 대해서 설명한다.Next, the operation and effects of the interlocking switch of the inlet and outlet of the air conditioner according to the present invention will be described.
공기조화기의 운전시에는 먼저, 사용자가 도시하지 않은 조작부의 조작조건을 선택하여 공기조화기를 가동시키면, 구동모터(52)가 구동되어 피니언(53)이 시계방향으로 회전함에 따라 상기 토출구차단수단(57)과 결합된 제1랙(55)이 하강하고, 상기 피니언(53)의 타측에 기어물림 됨과 동시에, 흡입구차단수단(63)과 결합된 제2랙(59)이 상승하여, 토출구(11) 및 흡입구(65)가 동시에 개방되고, 상기 흡입구(65) 및 흡입그릴수단(64)의 관통구멍(64a)을 통하여 실내공기가 흡입되어 도시하지 않은 열교환기에 의해 열교환된 후, 본체(1)의 상측에 배설된 좌우풍향조절날개(17) 및 상하풍향조절날개(15)에 의해 좌우 및 상하로 조절되어 토출구(11)를 통해 실내로 토출된다.In operation of the air conditioner, first, when the user selects the operating conditions of the operation unit (not shown) to operate the air conditioner, the driving motor 52 is driven so that the pinion 53 rotates in the clockwise direction. The first rack 55 coupled with the 57 is lowered, and the second rack 59 coupled with the suction port blocking means 63 is lifted up while being caught by the other side of the pinion 53, and the discharge port ( 11) and the suction port 65 are simultaneously opened, the indoor air is sucked through the through hole 64a of the suction port 65 and the suction grill means 64, and heat exchanged by a heat exchanger (not shown). The left and right wind direction control blades 17 and the up and down wind direction control blades 15 disposed on the upper side of the control panel are adjusted to the left and right and up and down and discharged into the room through the discharge port 11.
이때, 상기 흡입그릴수단(64)의 관통구멍(64a)은 크게 형성되어 흡입되는 공기의 양을 많게 함으로써, 공조효과를 높임과 동시에, 소음을 방지하게 된다.At this time, the through-hole 64a of the suction grill means 64 is formed to be large to increase the amount of air sucked, thereby enhancing the air conditioning effect and preventing noise.
한편, 공기조화기의 비가동시에는 도시하지 않은 조작부의 조작버튼을 선택하면, 구동모터(52)에 전원이 재인가되어 피니언(53)이 상기 흡입구(65) 및 토출구(11)를 개문시켰던 방향과 반대방향으로 회전됨에 따라 토출구차단수단(57)과 결합된 제1랙(55)이 상승하고, 상기 피니언(53)의 타측과 기어 물림됨과 동시에, 흡입구차단수단(63)과 결합된 제2랙(59)이 하강하여, 토출구(11) 및 흡입구(65)를 동시에 폐쇄시킴에 따라, 상기 토출구(11) 및 흡입구(65)를 통하여 이물질이나 먼지등이 유입되는 것을 방지한다.On the other hand, when the air conditioner is deactivated and the operation button (not shown) is selected, the power is reapplied to the drive motor 52 so that the pinion 53 opens the suction port 65 and the discharge port 11. As the first rack 55 coupled with the discharge port blocking means 57 rises and rotates in the opposite direction to the other side of the pinion 53, the second rack is coupled to the suction port blocking means 63. As the rack 59 descends and closes the discharge port 11 and the suction port 65 at the same time, foreign matter or dust is prevented from flowing through the discharge port 11 and the suction port 65.
이때, 상기 닫혀진 흡입구차단수단(63)은 흡입되는 공기의 양을 증대시키기 위하여 크게 형성된 흡입그릴수단(64)의 관통구멍(64a)을 가림으로써, 외관을 미려하게 할 뿐만 아니라 본체(1)의 내측으로 유입되는 이물질의 차폐효과를 높임으로써, 공기조화기의 성능저하를 효과적으로 방지한다.At this time, the closed suction port blocking means 63 covers the through hole 64a of the suction grill means 64, which is largely formed to increase the amount of air sucked therein, thereby not only beautifuling the appearance but also of the main body 1. By increasing the shielding effect of foreign matter introduced into the inside, it is effectively prevented the performance degradation of the air conditioner.
상술한 바와 같이 본 고안에 의한 공기조화기용 흡입구 및 토출구의 연동개폐장치에 의하면, 토출구차단수단 및 흡입구차단수단을 동시에 개폐시킴으로써, 공기조화기의 비가동시에 이물질이 유입되는 것을 효과적으로 방지함과 동시에, 흡입그릴수단의 관통구멍을 크게 형성하여 흡입되는 공기의 양을 증대시킴으로써, 공조효과를 높이고, 상기 흡입구차단수단을 배설함에 따라 흡입그릴부재의 흡입구를 통해 내부가 보이는 것을 방지하여 외관을 미려하게 할 수 있다는 매우 실용적인 고안이다.As described above, according to the interlocking opening and closing device of the air conditioner inlet and the discharge port according to the present invention, by simultaneously opening and closing the discharge port blocking means and the suction port blocking means, at the same time to effectively prevent foreign matters from entering the air conditioner when inactive, By increasing the amount of air sucked by forming a large through-hole of the suction grill means, to enhance the air-conditioning effect, and to prevent the inside to be visible through the suction port of the suction grill member as the discharge port blocking means is arranged to enhance the appearance It is a very practical design.
