Description
본 고안의 공기정화기의 방향제 개폐장치에 관한 것으로서, 더욱 상세하게는 공기정화기의 운전시 센서의 작동에 의해 실내공기가 과도하게 오염되었을때는 방향제를 취출하지 않고, 실내공기가 청정상태를 나타낼때만 선택적으로 방향제를 취출할 수 있도록 한 것이다.The present invention relates to a fragrance opening and closing device of the air purifier of the present invention, and more particularly, when the indoor air is excessively contaminated by the operation of the sensor during operation of the air purifier, the air freshener is not taken out, and is selected only when the indoor air shows a clean state. The fragrance can be taken out.
종래의 공기정화기의 방향제 개폐장치는 제1도 내지 제3도에 나타낸 바와같이, 공기정화기의 본체(1a) 전면의 흡입구(2a)로 부터 흡입된 공기가 전치필터를 통과하여 대향전극과 방전선에 의하여 이온화시켜서 필터(3a)로 먼지를 흡착시킨후 상기 본체(1a) 상부에 형성된 배기구(4a)로 배출시켰다.In the air freshener of the conventional air purifier, as shown in FIGS. 1 to 3, air sucked from the inlet port 2a on the front surface of the main body 1a of the air purifier passes through the prefilter so that the counter electrode and the discharge line are removed. Ionized by the filter 3a, dust was adsorbed by the filter 3a, and then discharged to the exhaust port 4a formed on the upper portion of the main body 1a.
또한, 본체(1a)의 상부에 장착된 원격제어부(5a)에는 상부에 표시부(5b)와 하부에 조작용스위치(5c)가 형성되고, 상기 본체(1a)내의 상부에 솔레노이드 밸브(26)와 연결된 방향제통(23a)이 설치되어 상기 조작용 스위치(5c)의 인위직인 조작에 의해 전원과 연결된 조작회로부에서 신호를 전달하여 상기 솔레노이드 밸브(26)를 작동시켰다.In addition, the remote control unit 5a mounted on the upper portion of the main body 1a is provided with a display portion 5b and an operation switch 5c at the upper portion, and a solenoid valve 26 and an upper portion in the main body 1a. A connected air freshener 23a was installed to transmit a signal from an operation circuit part connected to a power source by artificial manipulation of the operation switch 5c to operate the solenoid valve 26.
따라서, 제3(a)도 및 제3(b)도에 나타낸 바와같이, 솔레노이드 밸브(26) 선단의 축(21a)에 체결부재(28)로서 고정된 방향제통(23a) 상부의 방향제 커버(20a)의 열리는 양을 제어하여 방향제(9a)가 공기정화기의 본체(1a) 상부에 형성된 배기구(4a)를 통하여 배출되었다.Therefore, as shown in FIGS. 3 (a) and 3 (b), the fragrance cover (above the air freshener 23a fixed to the shaft 21a at the tip of the solenoid valve 26 as the fastening member 28) The opening amount of 20a) was controlled so that the air freshener 9a was discharged through the exhaust port 4a formed on the upper portion of the main body 1a of the air purifier.
그러나, 이와같은 종래의 공기정화기의 방향제 개폐장치는 실내공기의 오염상태와는 별개로 작동되므로 실내공기가 과도하게 오염되었을때에 방향제(9a)를 취출시키면, 공기중에 포함된 냄새 성분과 합성도이 악취로 변하므로 인한 사용자에게 불쾌감을 줄뿐만 아니라 방향제(9a)의 마스킹역활이 원활히 수행되지 않아서 실내공기를 더욱더 오염시키는 결과를 초래 했다.However, since the air freshener opening and closing device of the conventional air purifier is operated independently of the air polluted state, when the air freshener is taken out when the indoor air is excessively polluted, the smell component and the degree of synthesis contained in the air are different. Not only the discomfort to the user due to the change in odor, but also masking role of the air freshener (9a) was not performed smoothly and resulted in further contaminating the indoor air.
또한, 반드시 인위적으로 조작용스위치(5b)를 조작할때만 방향제(9a)의 취출이 가능하므로 실제로 사용시의 불편함이 있었으며, 특히 정화기의 운전중에 방향제(9a)를 취출하다가 운전을 정지했을때에도 방향제(9a)가 공기중에 노출된 상태로서 유지되기 때문에 실내공기중에 방향제(9a)의 취출이 계속되므로 인한 방향제(9a)의 사용수명을 단축시키는 등의 문제점이 있었다.In addition, since the air freshener 9a can be taken out only when the operating switch 5b is artificially operated, there is an inconvenience in use. In particular, the air freshener is taken out even when the air freshener 9a is taken out during operation of the purifier. Since 9a is maintained as exposed to the air, the air freshener 9a continues to be taken out in the indoor air, thereby reducing the service life of the air freshener 9a.
본 고안은 상기한 제반문제점을 해결하기 위한 것으로서, 본 고안은 공기정화기의 운전시 센서의 작동에 의해 실내공기가 심하게 오염되었을떼는 방향제를 취출하지 않고 실내공기가 청정상태를 나타낼 때만 선택적으로 방향제를 취출할 수 있을 뿐만 아니라, 운전정지 신호를 받으면 방향제가 취출되지 않는 공기정화기의 방향제 개폐장치를 제공하는데 그 목적이 있다.The present invention is to solve the above-mentioned problems, the present invention is to selectively remove the fragrance only when the indoor air indicates a clean state without taking out the fragrance that the indoor air is severely contaminated by the operation of the sensor during operation of the air purifier. It is an object of the present invention to provide a fragrance opening and closing device of an air purifier that can be taken out as well as a fragrance is not taken out when receiving a stop signal.

And a blowout hole 22a which is formed and coupled to the fragrance cover 20 and that is the same as the largest blowout hole 22 formed on the surface of the fragrance cover 20 on the top of the fragrance cylinder 23 containing the fragrance 9. Is formed to control the amount of ejection of the fragrance 9 according to the rotation of the step motor 19.
이와같이 구성된 본 고안은 제4도 내지 제9도에 나타낸 바와같이, 공기정화기에 전원(15)을 인가하면, 본체(1)내의 하부에 전동송풍기(도시하지 않음)가 작동을 개시하여, 상기 본체(1) 전면의 흡기구(2)로부터 실내의 공기를 유입하여 필터(3)에서 여가시킨후 상기 본체(1) 상부의 배기구(4)로 배출시킨다.4 to 9, when the power source 15 is applied to the air purifier, the electric blower (not shown) starts to operate in the lower part of the main body 1, and thus the main body is operated. (1) The air in the room is introduced from the inlet port 2 on the front side to allow the air to pass through the filter 3, and then the air is discharged to the exhaust port 4 on the upper portion of the main body 1.
한편, 제9도에 나타낸 바와같이, 가스센서(13)의 출력은 시간과 함께 연기의농도가 상승한다고 하면, 그 농도에 따라서 변화하므로 연기의 농도에 따라서 운전레벨을 변화시킨다.On the other hand, as shown in FIG. 9, if the output of the gas sensor 13 increases with time, the smoke level changes depending on the concentration, and thus the operation level is changed according to the concentration of the smoke.
즉, 연기가 없을때의 출력(Vo)에 대하여 연기의 농도가 높아짐에 따라서 V1, V2, V3와 같이 출력은 상승하며, 그때의 시간을 t1, t2, t3라 하면 각각의 시점에 있어서 운전능력은 "약"에서 부터 "중", "강"으로 크게된다.That is, the smoke, the output (Vo) the concentration of the smoke with an increase with respect to V 1, V 2, an output such as V 3 when there is a rise, assuming that the time period of t 1, t 2, t 3 la, respectively At this point, the driving ability increases from "weak" to "medium" and "strong".
또한, 제어부(16)는 가스센서(13)의 출력레벨이 "청정"일때만 스탭 모터(19)를 작동시키고, 실내공기의 오염도가 "약", "중", "강"상태에서는 작동되지 않도록 제어하므로써, 실내공기의 오염도가 "청정"일 경우에는 제6도 내지 제7도에 나타낸 바와같이, 스탭모터(19)를 작동시켜 상기 스탭모터(19)와 축(21)으로서 연결된 방향제커버(20) 표면의 크기가 다른 취출공(22)과 방향제통(23) 상부의 취출공(22a)이 일치되므로 인한 방향제(9)가 본체(1) 상부의 배기구(4)로 배출된다.In addition, the control unit 16 operates the step motor 19 only when the output level of the gas sensor 13 is "clean", and does not operate when the pollution level of the indoor air is "weak", "medium" or "strong". By controlling so that the pollution of the indoor air is " clean ", as shown in FIGS. 6 to 7, the fragrance cover connected to the step motor 19 and the shaft 21 by operating the step motor 19 is shown. (20) The air freshener (9) is discharged to the exhaust port (4) above the main body (1) because the blowout holes (22) having different sizes of surfaces coincide with the blowout holes (22a) at the top of the fragrance cylinder (23).
또한, 방향제커버(20)의 표면에는 크기가 다른 취출공(22)을 형성시키고, 방향제통(23)의 상부에는 상기 방향제커버(20) 표면에 형성된 제일큰 취출공(22)과 동일한 취출공(22a)을 형성시키므로 인한 방향제(9)의 필요량에 따라 상기 방향제커버(20)의 크기가 다른 취출공(22)을 상기 방향제통(23) 상부의 취출공(22a)과 일치시키므로써 방향제(9)의 취출량을 제어할 수 있게 된다.Further, a blowout hole 22 having a different size is formed on the surface of the fragrance cover 20, and the same blowout hole as the largest blowout hole 22 formed on the surface of the fragrance cover 20 is formed on the top of the fragrance cylinder 23. By forming the 22a, the blowing holes 22 having different sizes of the fragrance cover 20 according to the required amount of the fragrances 9 are matched with the blowing holes 22a on the upper portion of the fragrance cylinder 23. It is possible to control the ejection amount of 9).
또한, 방향제커버(20)의 취출공(22)과 방향제통(23)의 취출공(22a)이 일치되어 방향제(9)가 취출되는 시간은 원격제어부(5)의 타이머설정스위치(11)를 통해 입력된 소정의 시간을 타이머로 계수하고 계수가 완료되면 제어부(16)에서 스탭모터(19)에 작동 신호를 전달하여 제7(a)도에 나타낸 바와 같이, 방향제커버(20)를 회전시켜 상기 방향제통(23)을 밀폐시킨다.In addition, the time when the blowing hole 22 of the fragrance cover 20 and the blowing hole 22a of the fragrance cylinder 23 coincide with each other and the air freshener 9 is taken out is set to the timer setting switch 11 of the remote control unit 5. By counting the predetermined time input through the timer and when the count is completed, the control unit 16 transmits the operation signal to the step motor 19 to rotate the fragrance cover 20, as shown in Figure 7 (a) The fragrance cylinder 23 is sealed.
또한, 원격제어부(5)의 방향제취출스위치(8)를 수동상태로 설정했을 경우에는 자동운전과 마찬가지로 전동 송풍기의 회전수에 대응한 선택 표시등(10)이 점등되어 방향제커버(20)의 취출공(22)과 상기 방향제통(23)의 취출공(22a)을 일치시켜서 방향제(9)를 취출시킨다.In addition, when the fragrance taking-out switch 8 of the remote control unit 5 is set to the manual state, the selection indicator 10 corresponding to the rotational speed of the electric blower is turned on similarly to the automatic operation, and the fragrance cover 20 is taken out. The fragrance 9 is taken out by making the ball 22 and the blowout hole 22a of the said fragrance cylinder 23 match.
또한, 실내공기의 오염상태가 "약", "중", "강"일때는 스탭모터(19)가 작동되지 않고, 오염상태가 "청정"일때만 상기 스탭모터(19)가 작동되도록 방향제(9)를 취출시킨다.In addition, the step motor 19 does not operate when the pollution state of the indoor air is "weak", "medium", "strong", and the step motor 19 operates only when the pollution state is "clean". Take out 9).
한편, 제어부(16)는 정전이 아닌상태에서 운전 정지신호를 받으면, 방향제커버(20)의 취출공(22)과 방향제통(23)의 취출공(22a)의 일치여부를 판단하여 일치된 경우에는 스탭모터(19)를 작동시켜 상기 방향제통(23)내에 방향제(9)가 취출되지 않도록 상기 방향제커버(20)로서 밀폐시킨후 운전을 완전히 정지시킨다.On the other hand, when the control unit 16 receives the operation stop signal in a state where the power failure is not, the controller 16 determines whether or not the blowout hole 22 of the fragrance cover 20 and the blowout hole 22a of the fragrance bottle 23 are matched. After the step motor 19 is operated to seal the fragrance 9 in the fragrance cylinder 23 so that the fragrance 9 is not taken out, the operation is completely stopped.
이상에서와 같이, 본 고안은 실내공기의 오염상태를 원격제어부(5)에 형성된 가스센서(13)로서 감지하여 실내공기가 "청정"상태에서만 방향제(9)가 취출되도록 하므로써, 방향효과를 높일 수 있을 뿐만 아니라, 제어부(16)에서 운전을 정지하는 신호를 받으면 스탭모터(19)를 작공시켜 방향제(9)가 공기중에 노출되지 않도록 하여 방향제(9)의 사용수명 또한 대폭향상시킨 매우 유용한 고안이다.As described above, the present invention detects the polluted state of the indoor air as the gas sensor 13 formed in the remote control unit 5 so that the air freshener 9 is ejected only when the indoor air is in the "clean" state, thereby increasing the aroma effect. In addition, when the control unit 16 receives a signal to stop operation, the step motor 19 is constructed so that the fragrance 9 is not exposed to the air, thereby greatly improving the service life of the fragrance 9. to be.
