종래의 공기청정기는 특허등록 제10-2229865호(발명의 명칭 : 공기청정기)로 등록되어 특허공보에 의해 알려지고 있다.Conventional air purifiers have been registered as Patent Registration No. 10-2229865 (name of invention: air purifier) and are known through patent publications.

상기 종래의 공기청정기(700)는, 도 1에 도시된 바와 같이, 상하부가 개방된 청정기몸체(100)의 내측 중간에 공기유통공(111)이 형성된 필터지지판(110)이 설치되어 이 필터지지판(110)을 기준으로 상측에 팬수용공간(101)과, 하측에 필터수용공간(102)이 구비된다.As shown in FIG. 1, in the conventional air purifier 700, a filter support plate 110 having an air circulation hole 111 is installed in the middle of the inside of the purifier body 100 with open top and bottom parts, and the filter support plate 110 is installed. Based on (110), a fan accommodating space 101 is provided on the upper side and a filter accommodating space 102 is provided on the lower side.

상기 팬수용공간(101)에 송풍팬(610)이 설치되고, 송풍팬(610)이 설치된 팬수용공간(101) 상측의 개방된 공간에 공기토출부(410)를 포함하는 청정기상판(400)이 설치되며, 하측의 필터수용공간(102)에는 원통관 형태로 형성되는 필터(210)가 삽입 설치되며, 필터수용공간(102) 하측의 개구부에는 필터캡(300)이 개폐가능하게 설치된다.A blowing fan 610 is installed in the fan accommodating space 101, and a purifier top plate 400 including an air discharge unit 410 in an open space above the fan accommodating space 101 in which the blowing fan 610 is installed is installed, a filter 210 formed in a cylindrical tube shape is inserted into the filter accommodating space 102 at the lower side, and a filter cap 300 is installed to be able to open and close the lower opening of the filter accommodating space 102.

그리고, 상기 필터수용공간(102)에 대응하는 청정기몸체(100)에는 외부 공기를 필터수용공간(102) 측으로 흡입되게 하는 공기흡입부(120)가 형성되어 있다.In addition, an air intake 120 is formed in the purifier body 100 corresponding to the filter accommodating space 102 to suck external air into the filter accommodating space 102.

이와 같은 종래발명은 팬수용공간(101)에 설치된 송풍팬(610)의 회전동작에 의해 흡입력이 발생되면서 그 흡입력에 의해 외부공기가 청정기몸체(100) 하부 전둘레에 형성된 공기흡입부(120)를 통하여 필터수용공간(102)으로 흡입되게 되며, 이 필터수용공간(102)의 내부에는 원통관 형태로 형성된 필터(210)가 설치되어서 상기 필터수용공간(102)으로 흡입되는 외부공기가 필터(210)를 통과하면서 외부공기에 포함되어있는 먼지 등의 이물질이 필터(210)에 걸러지게 된다.In this prior art, suction power is generated by the rotational operation of the blowing fan 610 installed in the fan accommodating space 101, and external air is blown into the air intake unit 120 formed around the entire lower portion of the purifier body 100 is sucked into the filter accommodating space 102 through, and a filter 210 formed in a cylindrical tube shape is installed inside the filter accommodating space 102 so that the outside air sucked into the filter accommodating space 102 is filtered ( 210), foreign substances such as dust contained in the external air are filtered by the filter 210.

위와 같이 필터(210)에서 이물질이 걸러진 청정공기는 필터 상측에 설치된 필터지지판(110)의 중앙에 상하로 통하게 형성된 공기유통공(111)을 통하여 송풍팬의 흡입부로 흡입된 뒤에 송풍팬의 토출구와 연결된 청정기상판(400)의 공기토출부(410)를 통하여 외부로 토출되게 된다.As described above, the clean air from which foreign substances are filtered out by the filter 210 is sucked into the suction part of the blowing fan through the air distribution hole 111 formed vertically in the center of the filter support plate 110 installed on the upper side of the filter, and then through the discharge port of the blowing fan. It is discharged to the outside through the air discharge part 410 of the connected air purifier top plate 400.

그런데, 이와 같은 방식의 공기청정기 모두가 외부공기를 필터 내측으로 흡입시킬 때, 그 공기청정기 주변의 공간에 포함되는 습기와 이물질도 함께 흡입시켜서 이물질과 수분입자가 필터의 외부면과 필터의 공극에 걸리게 된다.However, when all air purifiers of this type suck outside air into the filter, moisture and foreign substances contained in the space around the air purifier are also sucked in, so that foreign substances and moisture particles are trapped between the outer surface of the filter and the air gap of the filter. it gets caught

이때, 수분입자는 먼지 등의 이물질입자를 포집하면서 필터의 공극을 빠르게 막아서 필터의 교체시기를 앞당기게 되고, 수분입자에 의해 필터가 쉽게 부패되는 비위생적인 문제가 있었다.At this time, the moisture particles quickly block the pores of the filter while collecting foreign particles such as dust, thereby advancing the replacement time of the filter, and there is an unsanitary problem that the filter is easily corrupted by the moisture particles.

상기와 같이 구성된 본 발명의 작용관계를 도 2 내지 도 8을 참고하여 설명하면 다음과 같다.The operational relationship of the present invention configured as described above will be described with reference to FIGS. 2 to 8.

본 발명에 의한 공기청정기(30)에 있어서, 공기청정기(30)의 제어부(미도시)에 포함된 스위치를 조작하여 팬모터(26b)를 구동시키게 되면 팬하우징(26a)의 내부에 설치된 송풍팬(26)이 회전하면서 공기청정기(30) 주변의 외부공기를 공기흡입부(22)를 통하여 케이싱(20) 내측의 필터수용공간(25)으로 흡입시킨다.In the air purifier 30 according to the present invention, when the fan motor 26b is driven by operating a switch included in a control unit (not shown) of the air purifier 30, the blowing fan installed inside the fan housing 26a. As the 26 rotates, external air around the air purifier 30 is sucked into the filter receiving space 25 inside the casing 20 through the air intake 22.

필터수용공간(25)으로 흡입된 외부공기에는 먼지 등의 이물질이 포함되어 있는데, 이물질을 포함한 외부공기가 필터(27)를 통과하면서 이물질은 필터(27)에 걸러지고, 청정공기는 필터(27) 내측공간에서 필터지지대(23)의 중앙부에 관통 형성된 공기유통공(23a)을 통하여 송풍팬(26)이 설치된 팬하우징(26a)을 거쳐서 공기토출부(21)로 배출된다.The external air sucked into the filter receiving space 25 contains foreign substances such as dust. As the external air including the foreign substances passes through the filter 27, the foreign substances are filtered by the filter 27, and the clean air is filtered by the filter 27. ) In the inner space, the air is discharged to the air discharge unit 21 through the air distribution hole 23a formed through the central portion of the filter support 23 through the fan housing 26a in which the blowing fan 26 is installed.

이때, 공기흡입부(22)를 통하여 필터수용공간(25)으로 흡입되는 외부공기에는 주변의 습도에 따라 수분입자가 먼지 등의 이물질과 함께 필터수용공간(25)으로 흡입되며 필터(27)에 투입되게 되는데, 본 발명에서는 도 2 내지 도 6에서 보는 바와 같이 필터(27) 외측의 필터수용공간(25) 내측에 필터건조장치부(10)가 설치되어서 필터수용공간(25)으로 흡입되는 외부공기와 필터(27)를 건조시켜 주게 된다.At this time, in the external air sucked into the filter accommodating space 25 through the air intake 22, moisture particles are sucked into the filter accommodating space 25 along with foreign substances such as dust according to the surrounding humidity, and the filter 27 In the present invention, as shown in FIGS. 2 to 6, the filter dryer unit 10 is installed inside the filter accommodating space 25 outside the filter 27, so that outside air sucked into the filter accommodating space 25 and the filter 27 is dried.

위와 같이 공기청정기(30)가 가동되는 상황에서 공기청정기(30)가 비치된 실내공간의 습도가 설정된 습도이상으로 습도감지센서(미도시)에 감지되면, 필터건조장치부(10)에 포함된 열선(18)이 발열되게 되는데, 습도감지센서에 습도가 감지되고 그렇게 감지된 신호에 따라 열선(18)이 온,오프되는 것은 공지된 제어부에 의해 제어되는 것임을 밝혀둔다.As described above, when the humidity of the indoor space in which the air purifier 30 is installed is detected by the humidity sensor (not shown) as higher than the set humidity in a situation where the air purifier 30 is operating, the heat wire included in the filter dryer unit 10 (18) generates heat. It should be noted that humidity is detected by the humidity sensor and that the heating wire 18 is turned on and off according to the detected signal by a known control unit.

상기와 같이 열선(18)이 발열되게 되면, 열선(18)이 설치된 열선설치틀(12)이 박판의 금속띠를 나선형으로 형성한 것이어서 열선(18)의 열기가 열선설치틀(12)에 빠르게 전도되어 열선설치틀(12)이 설치된 필터수용공간(25)의 내부온도가 상승하게 되고, 열선설치틀(12)이 필터(27)과 근접하게 설치되어서 열선(18) 및 열선설치틀(12)에서 발산하는 열기에 의해 필터(27)가 따뜻해지게 된다.As described above, when the hot wire 18 generates heat, the hot wire installation frame 12 in which the hot wire 18 is installed forms a thin metal strip in a spiral shape, so the heat of the hot wire 18 quickly spreads to the hot wire installation frame 12. The conduction causes the internal temperature of the filter accommodating space 25 in which the heating wire installation frame 12 is installed to rise, and the heating wire installation frame 12 is installed close to the filter 27 so that the heating wire 18 and the heating wire installation frame 12 The filter 27 is warmed by the heat emitted from ).
