본 발명의 실시 예에 따른 드럼식 건조기(A)의 동작설명은 하기와 같다.Operation of the drum dryer (A) according to an embodiment of the present invention is as follows.

도 2a 내지 도 3을 참조하여 보면서 설명하면, 먼저 배풍덕트(6)와 흡입덕트(10)간에 설치된 댐퍼(8)와 흡입덕트(10)와 히터(4)간에 설치된 댐퍼(8)(12)를 개방한 다음, 드럼(16)내로 건조가능한 세탁물이나 농산물 등을 넣고 드럼(16)을 구동시키면, 히터(14)가 가열되면서 흡입모터(4)에서 공기를 흡입하여 배풍덕트(6), 흡입덕트(10)를 지나 히터(14)를 관통하여 달권진 열기가 드럼(16)내로 공 급된다. 공급된 열기는 열손실 없이 드럼(16)의 배출측 외면에 형성된 통공(24)들을 빠져나와 본체(2) 전면부측 하부측에 형성된 회귀로(34)를 통하여 흡입모터(4)로 유입되면서 열기가 본체내에서 계속 강제회전하게 된다.2A to 3, first, the damper 8 provided between the air duct 6 and the suction duct 10 and the damper 8 and 12 provided between the suction duct 10 and the heater 4. After opening the laundry, agricultural products, etc., which can be dried into the drum 16, the drum 16 is driven, and the heater 14 is heated to suck the air from the suction motor 4 so that the air duct 6 is sucked. The moon winding heat is supplied into the drum 16 through the duct 10 and through the heater 14. The supplied heat exits the through-holes 24 formed on the outer side of the discharge side of the drum 16 without heat loss and enters the suction motor 4 through the return path 34 formed on the lower side of the front side of the main body 2. Will continue to rotate in the body.

이때 댐퍼(8)(12)들을 개방한 상태에서 열회전 시키게되므로 초기온도 상승시간이 짧아 히터(14)의 크기를 줄일 수 있게 된다.In this case, since the dampers 8 and 12 are thermally rotated in the open state, the initial temperature rise time is short, thereby reducing the size of the heater 14.

이러한 작동으로 드럼(16)내의 온도가 세탁물이나 농산물의 건조에 알맞는 일정온도에 도달하면 온도센서(18)가 감지하여 컨트롤러(22)에 의해 댐퍼(8)(12)들을 폐쇄하면서 히터(14)의 작동을 정지시키고 흡입모터(4)만을 회전시켜 열기가 더 이상 순환되지 않고 배풍덕트(6)의 배출부측을 통해 고온다습의 공기가 외부로 빠져나가게 된다. 어느정도 습기가 배출되면서 온도가 설정온도까지 내려가면 다시 댐퍼(8)(12)들을 개방하고 히터(14)를 가열하여 열기를 발생시키게 되고, 상기 동작을 반복하게 된다. 이때 댐퍼(8)(12) 폐쇄시 30∼60초 가량으로 습기를 배출하는 것이 바람직하고, 이 동작을 10∼15회정도 반복적으로 하는 것이 효과적이다.In this operation, when the temperature in the drum 16 reaches a certain temperature suitable for drying laundry or agricultural products, the temperature sensor 18 senses and closes the dampers 8 and 12 by the controller 22 and the heater 14. ) Is stopped and only the suction motor 4 is rotated so that hot air is not circulated any more, and the air of high temperature and high humidity flows out through the discharge side of the exhaust duct 6. When the temperature is lowered to a predetermined temperature while the moisture is discharged to some extent, the dampers 8 and 12 are opened again, and the heater 14 is heated to generate heat, and the above operation is repeated. At this time, it is preferable to discharge moisture at about 30 to 60 seconds when the dampers 8 and 12 are closed, and it is effective to repeat this operation about 10 to 15 times.

상기한 동작의 반복으로 드럼(16)내의 세탁물이나 농산물이 단시간내에 건조되고, 드럼(16)에서 배출되는 습기가 세탁물이나 농산물에 적합한 습도가 되면 회귀로(34)내에 부착된 습도센서(20)가 감지하여 컨트롤러(22)에 의해 전기공급이 중단되어 냉풍 싸이클로 전환되면서 건조기의 작동이 정지된다. 이때 세탁물이나 농산물에 적합한 습도는 제품에 따라 조건들이 각각 상이하지만 통상 5∼30％ 정도이다. 세탁물이나 농산물은 통상 완전건조 시키지 않고 반건조 시키는게 바람직하다.When the laundry or agricultural products in the drum 16 are dried in a short time by repeating the above operation, and the moisture discharged from the drum 16 becomes a humidity suitable for the laundry or agricultural products, the humidity sensor 20 attached to the return path 34 is provided. Is detected and the electricity supply is stopped by the controller 22 to switch to the cold wind cycle, the operation of the dryer is stopped. At this time, the humidity suitable for laundry or agricultural products is usually 5-30%, although conditions vary depending on the product. Laundry or agricultural products are usually semi-dried rather than completely dried.

또한 도 4에서처럼 배풍덕트(6)의 배출부측과 흡입덕트(10)의 배출부측간에 열회수기(44)를 연결설치 할 수도 있다. 열회수기(44)를 설치하면 배풍덕트(6)와 흡입덕트(10)간에 댐퍼(8)의 폐쇄시 고온다습의 공기가 배풍덕트(6)의 배출부측에 연결된 열회수기(44) 하부 배기공(46)으로 빠져나가면서 열회수기 상부측을 데워주게 되고, 열회수기(44)의 상부 흡입공(48)으로 외부신선공기가 자연유입되면서 다소 고온으로 가열되어 다시 히터(14)로 공급되어 재가열됨으로써 더욱 빠르게 온도가 상승하게 된다.In addition, as shown in FIG. 4, the heat recovery unit 44 may be connected between the discharge side of the exhaust duct 6 and the discharge side of the suction duct 10. When the heat recovery unit 44 is installed, the exhaust air of the lower part of the heat recovery unit 44 in which the air of high temperature and high humidity is connected to the discharge side of the exhaust air duct 6 when the damper 8 is closed between the air exhaust duct 6 and the suction duct 10. While exiting to 46, the upper side of the heat recovery unit is warmed up, and the external fresh air naturally flows into the upper suction hole 48 of the heat recovery unit 44, and is heated to a somewhat high temperature and is supplied to the heater 14 again to be reheated. As a result, the temperature rises more quickly.
