이로 인해, 흡입 열교환기(210)는 배풍 열교환기(220)를 통해 압송된 열전달매체로부터 열을 전도받아 흡입구(130)를 통해 유입되는 외부 공기를 가열시켜 건조기(100) 내부로 유입시키는 기능을 수행하게 된다.Therefore, the suction heat exchanger 210 receives heat from the heat transfer medium conveyed through the air exchange heat exchanger 220 to heat external air introduced through the suction port 130 to flow into the dryer 100. Will be performed.
또한, 본 발명은 건조기(100)의 건조실(120) 내의 온도와 습도를 온도센서(410)와 습도센서(420)에서 각각 측정한 후에, 각각의 측정값을 제어부(450)로 출력하고, 온도 측정값과 습도 측정값이 제어부(450)에 기 설정된 허용범위 값을 초과할 경우, 제어부(450)는 모터(320)에 제어신호를 출력하여 댐퍼(310)를 회수덕트(330) 측으로 회전시켜 배풍구(140)를 개방시킴으로써, 건조기(100)의 내부 온도와 습도를 낮출 수 있다.In addition, the present invention, after measuring the temperature and humidity in the drying chamber 120 of the dryer 100 by the temperature sensor 410 and the humidity sensor 420, respectively, and outputs each measured value to the controller 450, the temperature When the measured value and the humidity measured value exceed the allowable range values set in the controller 450, the controller 450 outputs a control signal to the motor 320 to rotate the damper 310 toward the recovery duct 330. By opening the exhaust port 140, the internal temperature and humidity of the dryer 100 can be lowered.
이와 반대로, 온도 측정값과 습도 측정값이 제어부(450)에 기설정된 허용 범위 내에 있거나, 그 이하일 경우에는 제어부(450)가 모터(320)에 제어신호를 출력하여 댐퍼(310)를 배풍구(140)측으로 정방향 회전시켜 회수덕트(330)를 개방시킴으로써, 건조기(100)의 내부 온도와 습도를 상승시킴과 아울러, 배풍 열교환기(220)와 흡입 열교환기(210)를 가열시켜 건조기(100) 내부로 유입되는 외부 공기를 가열시킬 수 있게 된다.On the contrary, when the temperature measurement value and the humidity measurement value are within or below a predetermined allowable range preset by the control unit 450, the control unit 450 outputs a control signal to the motor 320 to provide a damper 310 with a vent hole ( By rotating forward to 140 to open the recovery duct 330, the internal temperature and humidity of the dryer 100 are increased, and the exhaust heat exchanger 220 and the suction heat exchanger 210 are heated to dry the dryer 100. It is possible to heat the outside air introduced into the inside.
이때, 건조실(120) 내의 온도에 따라 잎담배의 수분은 비례하여 변하게 되므로, 제어부(450)의 기설정 범위에 해당하는 온도는 상기 건조실(120) 내의 온도를 기준으로 30~90℃의 범위가 바람직하며, 또한 상기 건조실(120) 내로 입고되는 잎담배의 종류 및 수확되는 잎담배의 부위별 건조 조건 및 건조 시간에 따라 상기 건조실(120) 내의 온도와 습도가 조절되도록 제어하는 것이 바람직하다. 이는, 잎담배의 종류 및 부위별로 건조에 요구되는 온도 및 습도와 시간이 가변되기 때문이다.At this time, since the moisture of the leaf tobacco changes in proportion to the temperature in the drying chamber 120, the temperature corresponding to the preset range of the controller 450 is preferably in the range of 30 ~ 90 ℃ based on the temperature in the drying chamber 120. In addition, it is preferable to control the temperature and humidity in the drying chamber 120 to be controlled according to the drying conditions and drying time for each type of leaf tobacco to be put into the drying chamber 120 and harvested leaf tobacco. This is because the temperature, humidity and time required for drying are varied according to the type and part of the leaf tobacco.
이로 인해, 본 발명은 건조실(120) 내의 온도 및 습도를 측정하고, 측정된 온도 및 습도와 건조시간에 따라 제어부(450)가 댐퍼(310)의 개폐방향을 선택하면, 댐퍼(310)가 역방향으로 회전되어 건조실(120) 내의 고온 다습한 공기가 배풍구(140)를 통해 외부로 배출되거나, 댐퍼(310)가 정방향으로 회전되어 건조실(120) 내의 공기가 회수덕트(330)를 통해 다시 건조실(120) 내로 순환되는 공기 흐름경로를 갖는다.For this reason, the present invention measures the temperature and humidity in the drying chamber 120, and when the control unit 450 selects the opening and closing direction of the damper 310 according to the measured temperature and humidity and drying time, the damper 310 is reversed Rotated to a high temperature and high humidity in the drying chamber 120 is discharged to the outside through the vent holes 140, or the damper 310 is rotated in the forward direction so that the air in the drying chamber 120 again through the recovery duct 330 It has an air flow path circulated into 120.
도 5는 본 발명의 다른 실시예를 나타낸 도면으로서, 앞서 설명한 선 실시예의 구성요소를 가지며, 배풍구(140) 내에 마련되고 상기 제어부(450)의 제어신호에 따라 구동되어 상기 건조실(120) 내의 내부공기를 흡입하여 송풍하기 위한 배출팬(510)을 더 구비한 것이다.5 is a view showing another embodiment of the present invention, which has the components of the above-described line embodiment, is provided in the ventilating opening 140 and driven in accordance with a control signal of the control unit 450 to operate in the drying chamber 120. It is further provided with a discharge fan 510 for sucking and blowing the internal air.
상기 배출팬(510)은 제어부(450)의 제어신호에 따라 구동되는 구동모터(520)에 의해 회전 구동되어 건조실(120) 내의 공기를 배풍구(140)측으로 흡입 송풍하는 기능을 수행하게 된다.The discharge fan 510 is rotationally driven by the driving motor 520 driven according to the control signal of the controller 450 to perform a function of sucking and blowing the air in the drying chamber 120 toward the vent hole 140.
이는, 건조실(120) 내의 온도 및 습도가 급격하게 올라갈 경우, 건조실(120) 내의 고온 다습한 공기가 배풍구(140)를 통해 신속하게 배출되도록 함으로써, 건조실(120) 내의 온도 조절을 허용 온도 범위내로 간편하고 신속하게 유지시킬 수 있는 이점을 갖는다.This is because, when the temperature and humidity in the drying chamber 120 rises rapidly, the hot and humid air in the drying chamber 120 is quickly discharged through the vent holes 140, thereby allowing the temperature control in the drying chamber 120 to be controlled in the temperature range. It has the advantage of being able to keep it simple and quick.
도 6은 본 발명 회수덕트의 다른 변형 실시예를 보인 도면으로, 회수덕트(330)의 내부에 상기 제어부(450)의 제어신호에 따라 구동되는 송풍모터(560)와, 상기 송풍모터(560)의 구동시 상기 회수덕트(330) 내의 공기를 흡입하여 상기 건조실(120) 내로 송풍하기 위한 송풍팬(550)을 더 구비한 것이다.6 is a view showing another modified embodiment of the recovery duct of the present invention, the blower motor 560 and the blower motor 560 which are driven in accordance with the control signal of the control unit 450 inside the recovery duct 330. In addition, a blower fan 550 may be further provided to suck air in the recovery duct 330 and blow air into the drying chamber 120.
제어부(450)는 댐퍼(310)의 정방향 회전 및 댐퍼(310)의 정방향 회전을 접촉식 센서 또는 비접촉식 센서를 이용하여 댐퍼(310)의 회전을 감지하고 일정시간이 지난 후에도 건조실(120) 내의 온도 상승이 미비할 경우 이 온도 변화를 감지하고 분석한 후에 송풍모터(560)를 구동시키는 제어신호를 출력하여 송풍팬(550)을 회전시킴으로써, 회수덕트(330) 내의 공기를 건조실(120) 내로 강제 순환시킬 수 있다.The controller 450 detects the rotation of the damper 310 by using the contact sensor or the non-contact sensor in the forward rotation of the damper 310 and the forward rotation of the damper 310, and the temperature in the drying chamber 120 even after a predetermined time has elapsed. If the rise is insufficient, the temperature change is sensed and analyzed, and then a control signal for driving the blowing motor 560 is output to rotate the blowing fan 550, thereby forcing the air in the recovery duct 330 into the drying chamber 120. Can be circulated.
이 경우, 제어부(450)는 댐퍼(310)의 정,역방향 개폐 동작시간을 연산하고, 습도의 비율을 판단한 후에 열 회수기능과 배습량을 조절할 수 있다.In this case, the controller 450 may calculate the forward / reverse opening / closing operation time of the damper 310, and after determining the ratio of humidity, may adjust the heat recovery function and the moisture absorption amount.
도 7 및 도 8은 본 발명의 또 다른 실시예를 보인 구성도로서, 상기 흡입구(130)는 상기 흡입 열교환기(210)가 배치된 제 1흡입구(130A)와, 상기 제 1흡입구(130A)와 격벽으로 구획되는 제 2흡입구(130B)로 구분되며, 상기 제 1,2흡입구(130A,130B)를 구분하는 격벽에 회동 가능하게 배치되어 상기 제 1,2흡입구(130A,130B) 중 하나를 개폐시키는 개폐댐퍼(600), 및 상기 개폐댐퍼(600)를 회전시키는 회동모터(650)를 더 구비한 것이다.7 and 8 is a configuration diagram showing another embodiment of the present invention, the inlet 130 is a first inlet 130A and the first inlet 130A, the intake heat exchanger 210 is disposed, the first inlet 130A And a second suction hole 130B partitioned into a partition wall, and rotatably disposed at a partition wall separating the first and second suction holes 130A and 130B, thereby allowing one of the first and second suction holes 130A and 130B to be separated.

Since it directly flows into the dryer 100 without passing through the suction heat exchanger 210, the internal temperature of the drying chamber 120 may be quickly cooled to an appropriate temperature.
