Description

상하 열풍 순환식 전기 건조기{A drying apparatus for upper and lower circulating}BACKGROUND OF THE INVENTION 1. Field of the Invention [0001]

본 발명은 건조기에 관한 것으로, 더욱 상세하게는 아래쪽 방향과 위쪽 방향을 번갈아 가면서 열풍을 순환시켜 고른 건조기술을 제공할 수 있는 상하 열풍 순환식 전기 건조기에 관한 것이다.
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dryer, and more particularly, to an upper and lower hot air circulating type electric dryer capable of circulating hot air while alternating between a downward direction and an upward direction to provide an even drying technique.

일반적으로 열풍 건조기는 버너나 히터로부터 열풍을 만들어 건조실내로 공급해주고, 이를 다시 버너나 히터로 회수하여 재공급해주는 반복된 작용으로 구성된다. 이러한 열풍 건조기는 건조실내에 하부에서부터 상부까지 여러 개의 건조상자를 적층시킨 후, 열풍을 공급하여 건조상자에 올려진 피건조물을 건조시키게 된다.In general, a hot air dryer is a repetitive operation that generates hot air from a burner or a heater and supplies it to a drying chamber, which is then returned to a burner or a heater for re-supply. In this hot air dryer, several drying boxes are stacked from the lower part to the upper part in the drying room, and hot air is supplied to dry the laundry placed on the drying box.

이와 같은 건조기는 바람의 방향에 따라 밑바람식과 옆바람식으로 구분되는데, 밑바람식 열풍 건조기는 최초로 열풍이 공급되는 하부층의 건조상자와 마지막으로 열풍이 빠져나가는 상부층의 건조상자간의 온도차이로 인해 상부층과 하부층의 피건조물의 건조차가 발생되어 일정한 시간이 흐른뒤에는 상부층과 하부층의 건조상자를 교체해 주어야 하는 문제점이 발생되었다.Such a dryer is divided into a bottom wind type and a side wind type according to the direction of the wind. The bottom wind type hot air dryer dries the upper layer due to the difference in temperature between the drying box of the lower layer to which the hot air is supplied first and the drying box of the upper layer, And the dryness of the laundry to be dried in the lower layer is generated, and after a certain period of time, the drying boxes of the upper and lower layers have to be replaced.

또한, 옆바람식 열풍 건조기는 열풍이 옆에서 공급되기 때문에 건조상자의 양측부와 중앙부의 온도차이로 인해 피건조물의 건조차이가 발생되는 문제점이 있었다.In addition, since the hot wind is supplied from the side in the side wind type hot air dryer, there is a problem in that drying difference of the laundry is caused due to the temperature difference between the both side portions and the center portion of the drying box.

이러한 문제점들을 해결하기 위해 안출된 것이 대한민국 특허 제10-0822809호(2008.04.17. 공고)인 "열풍의 방향을 반전시켜 피건조물의 상하층간 건조율을 균일하게 할 수 있는 열풍 건조기 및 건조방법"(이하, "선행기술1"이라 한다.)이 개시된 바 있다.In order to solve these problems, Korean Patent No. 10-0822809 (published on Mar. 17, 2008), entitled " Hot Air Dryer and Drying Method for Inverting the Direction of Hot Air, (Hereinafter, referred to as "Prior Art 1").

위 선행기술1에 의하면, 열풍이 건조실의 아래에서부터 위로 공급되도록 할 수도 있고, 또는 건조실의 위에서부터 아래로 공급될 수 있도록 할 수도 있는 열풍 건조기를 제공하는데 있다.According to the above prior art 1, hot air can be supplied from below the drying chamber, or can be supplied from the top to the bottom of the drying chamber.

구체적인 구조를 살펴보면, 건조실에 건조상자를 다단으로 적층하여 통상의 열원으로부터 발생된 열풍을 건조실과 열원을 순환시키면서 피건조물을 건조시키는 열풍 건조기에 있어서,The present invention relates to a hot-air dryer for drying a drying object by circulating a hot air generated from an ordinary heat source in a drying chamber and a heat source by laminating a drying box in a drying chamber in multiple stages,

상기 건조실은 상부측에서 연통되도록 격벽에 의해 등분된 제1건조실 및 제2건조실로 구성되고, 상기 제1건조실의 측벽에는 열풍이 순환되는 네 개의 입출구가 형성되되, 대각선으로 마주보는 입출구는 상기 제1건조실을 통과하여 상기 제2건조실로 연통되며, 상기 네 개의 입출구의 사이에는 위나 아래의 두개 입출구를 동시에 막을수 있는 반전판이 설치되는 것을 특징으로 하고 있다.The drying chamber is composed of a first drying chamber and a second drying chamber divided by a partition wall so as to be communicated at the upper side, and four side walls of the first drying chamber are formed with four outlets for circulating hot air. 1 drying chamber and communicates with the second drying chamber, and an inverting plate is installed between the four inlet and outlet ports to block the upper and lower two outlets at the same time.

그러나 상기 선행기술1은 건조실의 측면에 4개의 입출구를 형성하면서 이들을 반전판으로 제어해야 하므로 구조가 복잡해 규격이 자유롭지 못한 문제점과, 건조실의 아래쪽으로 4개의 입출구가 통과해야 하므로 건조기 전체 크기에 비해 건조상자의 적층양이 적은 문제가 있었다. 또한, 열풍 발생부가 건조기의 옆쪽에 돌출되어 있어 필요 이상의 공간 차지가 문제로 지적되어 왔다.
However, in the prior art 1, since four outlets are formed on the side surface of the drying chamber and they are controlled by a reversing plate, the structure is complicated and the specification is not free. In addition, since four outlets are required to pass through the lower portion of the drying chamber, There was a problem that the stacking amount of the box was small. Further, since the hot air generating portion is protruded on the side of the dryer, it has been pointed out that the space occupation is more than necessary.

본 발명은 상기한 선행기술처럼 열풍을 상하로 반전시키면서 건조시키되, 열풍발생부를 건조기의 상부에 설치하여 선행기술의 모든 문제점을 해결한 상하 열풍 순환식 전기 건조기를 제공하는데 있다.

또한, 송풍팬은 초기 건조구간에서는 송풍량을 최대로 하면서 중후반으로 넘어갈수록 송풍량을 점차 줄이도록 제어부에 의해 스피드가 콘트롤될 수 있다.
In addition, the speed of the blowing fan can be controlled by the control unit so that the blowing amount gradually decreases as the blowing amount is increased to the middle and rear half while the blowing amount is maximized in the initial drying period.

전술한 바와 같이 본 발명에 따른 건조기는 송풍팬의 사이에 설치된 흡배기구를 열거나 닫으면서 구동시킬 수 있어 흡배기구를 열었을때에는 충분한 외기의 유입이 가능해 지면서 흡배기구를 닫았을때에는 고추 등과 같이 찜을 필요로 하는 특정 농산물의 찌는 구간을 설정할 수도 있게 된다.As described above, the dryer according to the present invention can be driven by opening and closing the intake and exhaust port provided between the blowing fans, so that when the intake and exhaust port is opened, sufficient outside air can be introduced, and when the intake and exhaust port is closed, It is also possible to set the steaming interval of the specific agricultural product needed.

본 발명은 동일 발명자에 의해 선출원된 한국 등록특허 제1214779호(2012.12.21. 공고, 명칭 : 상하 순환식 건조기)(이하, "선행기술2"라 한다.)의 연속 발명임을 밝히면서, 선행기술2의 구조를 간략하게 살펴본다.The present invention is a continuous invention of Korean Patent No. 1214779 (hereinafter referred to as " Prior Art 2 "), which was filed by the same inventor, A brief overview of the structure of

도 1은 선행기술2를 나타낸 도면으로서, 상기 선행기술2는 첨부된 도면에서 보는 것과 같이, 피건조물이 저장되는 건조실(20)과, 건조실(20)의 하부와 연통되는 열풍통로(30)와, 건조실(20)의 상부와 열풍통로(30)의 상부를 연통시키는 순환통로(40)와, 순환통로(40)의 양쪽에 설치되는 순환팬(50)과, 순환팬(50)들의 사이 순환통로(40)에 설치되는 히터(60)와, 순환통로(40)의 중간부에서 건조실(20) 방향 및 열풍통로(30) 방향으로 연통되는 제1우회로(70) 및 제2우회로(75)와, 제1우회로(70) 및 제2우회로(75)를 선택적으로 열고 닫는 개폐기(85);를 포함하여 구성된다.1 is a view showing a prior art 2. As shown in the accompanying drawings, the prior art 2 includes a drying chamber 20 in which a drying object is stored, a hot air passage 30 communicating with a lower portion of the drying chamber 20, A circulation passage 40 for communicating the upper portion of the drying chamber 20 with the upper portion of the hot air passage 30, a circulation fan 50 installed on both sides of the circulation passage 40, A heater 60 installed in the passage 40 and a first bypass circuit 70 and a second bypass circuit 75 communicating with each other in the direction of the drying chamber 20 and the hot air passage 30 in the middle of the circulation passage 40, And a switch 85 for selectively opening and closing the first bypass circuit 70 and the second bypass circuit 75.

상기 선행기술2는 하나의 건조실(20)과, 이 건조실(20)의 측면에 열풍이 이동되는 통로(30)를 형성하여 이 건조실과 통로를 상,하 번갈아 가면서 순환시키는 기술을 제공하였었다.The prior art 2 has provided a drying chamber 20 and a passage 30 through which hot air is moved on the side surface of the drying chamber 20 so as to circulate the drying chamber and the passage alternately.

그러나 건조기가 대형화(좌우로)가 되면 열풍통로(30)를 확장하여 제2건조실로 사용될 수도 있음은 당연할 것이다. 이와 같이 제2건조실이 늘어난 관계로 건조용량은 2배로 증가하게 됨은 당연할 것이고, 이러한 구조라면 순환팬의 용량을 더 크게 늘려야한다. 즉, 순환팬에서 발생된 바람은 건조상자를 통과하면서 정압이 손실되는데, 선행기술2에서 사용된 순환팬으로는 손실된 정압을 보상할 방법이 없게 되는 것이다.However, it is natural that when the dryer becomes large (left and right), the hot air passage 30 may be extended to be used as the second drying chamber. As a result, the drying capacity is doubled as a result of the increase in the second drying chamber. In such a structure, the capacity of the circulating fan must be increased. That is, the wind generated from the circulating fan is lost through the drying box while the static pressure is lost. In the circulating fan used in the prior art 2, there is no way to compensate the lost static pressure.

본 발명은 위와 같은 정압손실을 온도로 보상해 주기 위한 발명으로서, 선행기술2와 같이 소용량의 송풍팬을 사용하면서도 건조효율을 떨어뜨리지 않도록 하는 것을 특징으로 한다.The present invention is an invention for compensating for the above-described static pressure loss with temperature, and is characterized in that drying efficiency is not lowered even though a small-capacity blowing fan is used as in the prior art 2.

또한, 본 발명은 2개의 송풍팬 사이에 흡배기구를 설치하여 이 흡배기구에 의해 외기의 유입을 효율적으로 콘트롤할 수 있으면서 특정 농산물에 대한 건조시에 찜을 찌는 구간을 설정할 수도 있게 된다.In addition, in the present invention, an intake and exhaust port is provided between two blowing fans so that the inflow of outside air can be efficiently controlled by the air intake and exhaust port, and a section in which steam is steamed during drying for a specific agricultural product can be set.

도 2는 본 발명에 따른 건조기를 나타낸 도면으로서, 본 발명에 따른 건조기(100)는 다수의 건조상자(121)가 상,하로 놓여지도록 내부에 건조실(120)이 형성된 본체(110)를 포함하며, 이 건조실(120)내에는 양쪽 좌우를 등분하도록 구획판(130)에 의해 건조실(120)이 2개로 분할된다. 이때, 구획판(130)의 하부는 양쪽 제1건조실(120a) 및 제2건조실(120b)을 횡방향으로 관통하도록 열풍순환로(132)가 형성된다.FIG. 2 is a view illustrating a dryer according to the present invention. The dryer 100 according to the present invention includes a main body 110 in which a drying chamber 120 is formed so that a plurality of drying boxes 121 are placed on top and bottom, , And the drying chamber 120 is divided into two by the partition plate 130 so as to equally divide both sides of the drying chamber 120 into two. At this time, the lower part of the partition plate 130 is formed with the hot air circulation path 132 so as to pass through both the first drying room 120a and the second drying room 120b in the lateral direction.

이렇게 형성된 본체(110)의 상부면상에는 제1건조실(120a) 및 제2건조실(120b)로 열풍을 공급하거나 배출시키는 열풍공급부(140)가 형성된다.On the upper surface of the body 110 thus formed, a hot air supply unit 140 for supplying or discharging hot air to the first drying chamber 120a and the second drying chamber 120b is formed.

열풍공급부(140)는 함체 형상을 갖는 하우징(142)과, 이 하우징(142)내의 양측에 설치되는 송풍팬(150)과, 송풍팬(150)의 하부측에 설치되는 전기히터(160)를 포함한다.The hot air supply unit 140 includes a housing 142 having a housing shape, a blowing fan 150 installed at both sides of the housing 142, and an electric heater 160 installed at a lower side of the blowing fan 150 .

제1송풍팬(150a) 및 제2송풍팬(150b)은 서로 마주보도록 설치되어 그 아래쪽의 전기히터(160)를 향해 송풍시키며, 전기히터(160)에 의해 가열된 열풍은 그 아래쪽의 건조실(120)로 송풍된다. 따라서 제1건조실(120a) 및 제2건조실(120b)의 상부 천장에는 하우징(142)과 개방되어 열풍을 공급받거나 배출하도록 제1입출로(144a) 및 제2입출로(144b)가 형성된다.The first blowing fan 150a and the second blowing fan 150b are installed so as to face each other and blow air toward the electric heater 160 below the blower fan 150. The hot air heated by the electric heater 160 flows into the drying chamber 120). Thus, the first and second drying chambers 120a and 120b are opened to the housing 142 to form a first inlet / outlet passage 144a and a second inlet / outlet passage 144b for receiving or discharging hot air.

본 발명에 따른 열풍공급부(140)는 건조실(120)내를 순환한 열풍을 그대로 다시 재순환시키거나 아니면 전량 외부로 배출하여 새로운 외기에 의한 건조를 시도할 수 있게 된다.The hot air supply unit 140 according to the present invention can re-circulate the hot air circulated in the drying chamber 120 as it is or can discharge the entire amount of the hot air to the outside and attempt drying with fresh outside air.

따라서 제1송풍팬(150a)과 제2송풍팬(150b)은 서로 연통되어 있지만 그 사이에 종방향 및 횡방향으로 회동될 수 있는 흡배기구(170)가 설치된다. 이러한 흡배기구(170)가 도 3a에서 보는 것과 같이, 종방향으로 세워졌을때에는 어느 일측의 정지되어 있는 송풍팬(150a)쪽으로 토출된 열풍이 세워진 흡배기구(170)에 막혀 구동중인 송풍팬(150b)쪽으로 순환되지 않고 바로 외부로 배출된다. 반대로 흡배기구(170)가 횡방향으로 누워졌을때에는 도 3b에서 보는 것과 같이, 어느 일측의 정지되어 있는 송풍팬(150a)쪽으로 토출된 열풍이 누워진 흡배기구(170)가 상부쪽을 막고 있어 구동중인 송풍팬(150b)쪽으로 순환되면서 순환을 완료한 열풍이 다시 재순환시킬 수 있게 된다.Accordingly, although the first blowing fan 150a and the second blowing fan 150b are in communication with each other, an intake and exhaust device 170 capable of rotating longitudinally and laterally is provided therebetween. As shown in FIG. 3A, when the intake and exhaust device 170 is vertically erected, the hot air blown to one of the stopped blowing fans 150a is blocked by the built-in intake and exhaust device 170 and the blowing fan 150b But is discharged directly to the outside. On the contrary, when the intake and exhaust device 170 is laid in the lateral direction, as shown in FIG. 3B, the intake and exhaust device 170 in which hot air discharged to one side of the blowing fan 150a, The hot air that has been circulated while being circulated to the blowing fan 150b in which the circulation is completed can be recirculated again.

이처럼 흡배기구(170)를 닫아 열풍을 재순환시키는 이유는 고추 등과 같은 특정 농산물은 건조의 처음 단계에서 찜을 찌는 구간이 필요하게 되는데, 이러한 경우에 사용하려는 목적에서이다.The reason why the intake / exhaust device 170 is closed to recirculate the hot air is that the specific agricultural products such as red pepper and the like require an interval during which the steam is steamed at the initial stage of drying.

본 발명에 따른 건조기(100)는 2개의 송풍팬(150)중에서 어느쪽 송풍팬을 구동시키느냐에 따라 건조기의 순환구조가 달라지게 된다. 즉, 우측의 제2송풍팬(150b)을 구동시키게 되면 도 4에서 보는 것과 같이, 제1송풍팬(150a)은 정지하게 되고, 제2송풍팬(150b)에 의해 발생된 풍량은 제2전기히터(160b)를 통과하면서 가열되며, 이 가열된 열풍이 제2건조실(120b) 및 제1건조실(120a)을 시계방향으로 순환하면서 다시 제1송풍팬(150a)을 통해 토출된다. 반대로 좌측의 제1송풍팬(150a)을 구동시키게 되면 도 4의 화살표 역순 방향에 따라 제2송풍팬(150b)은 정지하게 되고, 제1송풍팬(150a)에 의해 발생된 풍량은 제1전기히터(160a)를 통과하면서 가열되며, 이 가열된 열풍이 제1건조실(120a) 및 제2건조실(120b)을 반시계방향으로 순환하면서 다시 제2송풍팬(150b)을 통해 토출된다.In the dryer 100 according to the present invention, the circulation structure of the dryer varies depending on which of the two blowing fans 150 is driven. That is, when the second blowing fan 150b on the right side is driven, the first blowing fan 150a is stopped and the air volume generated by the second blowing fan 150b is stopped as shown in FIG. Is heated while passing through the heater 160b and the heated air is discharged through the first blowing fan 150a while circulating the second drying chamber 120b and the first drying chamber 120a in the clockwise direction. On the contrary, when the first blowing fan 150a on the left side is driven, the second blowing fan 150b is stopped along the direction reverse to the arrow in FIG. 4, and the air volume generated by the first blowing fan 150a is stopped The heated air is discharged through the second blowing fan 150b while circulating the first drying chamber 120a and the second drying chamber 120b counterclockwise.

여기에서, 제1전기히터(160a) 및 제2전기히터(160b)는 그쪽의 송풍팬 구동에 따라 자동으로 ON/OFF 된다. 즉, 송풍팬들은 하향으로 송풍되므로, 구동되는 송풍팬쪽의 아래쪽에 위치한 전기히터가 ON 되고, 반대쪽 전기히터는 OFF 되도록 제어된다.Here, the first electric heater 160a and the second electric heater 160b are automatically turned on / off according to the driving of the blower fan. That is, since the blowing fans are blown downward, the electric heaters located on the lower side of the blowing fan to be driven are turned ON and the other electric heaters are controlled to be OFF.

본 발명에 따른 건조기(100)는 작은 용량의 송풍팬(150)에 의한 정압손실을 보상해 주기 위해 열풍순환의 중간지점에 제3전기히터(160c)를 추가로 구성한다. 즉, 구획판(130)의 하부에 형성된 열풍순환로(132)에 제3전기히터(160c)를 설치하여, 순환되는 열풍에 열에너지를 보충해 줌으로서 정압손실의 보상이 가능해 지는 것이다.The dryer 100 according to the present invention further comprises a third electric heater 160c at the midpoint of the hot air circulation to compensate for the static pressure loss due to the small capacity blowing fan 150. [ That is, the third electric heater 160c is installed in the hot-air circulation path 132 formed in the lower part of the partition plate 130 to compensate for the static pressure loss by supplementing the heat energy to the circulated hot air.

이는 송풍팬(150)에서 공급된 바람이 제1건조실(120a) 또는 제2건조실(120b)을 통과하면서 급격히 떨어지게 되는데, 이때에 열원을 보충해주어 정압손실에 의해 풍량이 약한 건조실쪽의 건조효율을 높이기 위한 방안이다. 이러한 작동방법은 한쪽 방향으로만 오랫동안 작동시키면 제1건조실(120a)쪽 피건조물과 제2건조실(120b)쪽 피건조물이 다르게 건조될 수 있으므로 일정시간을 두고 교대로 작동시키는 것이 필요할 것이다.This is because the air supplied from the air blowing fan 150 rapidly drops while passing through the first drying chamber 120a or the second drying chamber 120b. At this time, since the heat source is supplemented, the drying efficiency of the drying chamber, It is a plan to increase. In this operation method, if the drying operation is performed in only one direction for a long time, the drying items on the side of the first drying chamber 120a and the drying objects on the side of the second drying room 120b may be dried differently.

한편, 본 발명에 따른 건조기(100)는 전기히터(160)와 송풍팬(150)의 콘트롤은 물론, 흡배기구(170)를 콘트롤하는 제어부를 더 포함하여 구성될 수 있다. 제어부는 위 시계방향 열풍순환 및 반시계방향 열풍순환을 위해 각 구성부들을 콘트롤하며, 흡배기구(170)의 개폐를 콘트롤한다. 따라서 흡배기구(170)는 이를 회동시키기 위한 구동모터(도시되지 않음)가 구비되어 제어부에 의해 작동되고, 이 구동모터에 흡배기구(170)의 중심에 위치한 회동축이 연결된다.The dryer 100 according to the present invention may further include a controller for controlling the intake and exhaust device 170 as well as the electric heater 160 and the blowing fan 150. The control unit controls the respective components for the upward clockwise hot circulation and the counterclockwise hot air circulation, and controls the opening and closing of the intake and exhaust device 170. Accordingly, the intake and exhaust device 170 is provided with a drive motor (not shown) for rotating the intake and exhaust device 170, and the rotation shaft located at the center of the intake and exhaust device 170 is connected to the drive motor.

또한, 본 발명에 따른 송풍팬(150)은 제어부에 의해 스피드가 콘트롤되어 송풍량을 조절할 수 있다. 본 발명에 따른 건조기(100)는 전술한 바와 같이 흡배기구(170)의 작동이 완전 닫히거나 또는, 완전 열리는 구조인데, 찜을 찌는 초기 구간외에는 항상 열려진 상태로 작동될 수 밖에 없다. 초기의 건조구간에는 배습량이 많기 때문에 송풍량을 최대로 해도 되나, 점차 배습량이 작아지는 중후반 구간에서는 굳이 송풍량을 최대로 하여 필요 이상의 에너지 낭비를 할 필요가 없게 되는 것이다. 따라서 초기 작동구간에는 송풍팬을 최대로 돌리면서 점차 송풍량을 줄여 열효율 및 건조효율을 높이기 위해 송풍팬(150)의 스피드 콘트롤이 필요하게 되는 것이다.
Further, the blowing fan 150 according to the present invention can control the blowing amount by controlling the speed by the control unit. As described above, the dryer 100 according to the present invention is structured such that the operation of the intake and exhaust device 170 is completely closed or fully opened. However, the dryer 100 can not be operated at all times except for the initial period when the steam is steamed. In the initial drying section, the amount of air blowing can be maximized because of a large amount of air to be drained. However, in the middle and rear sections where the amount of air to be drained gradually decreases, the air blowing amount is maximized. Therefore, in the initial operation period, the speed control of the blowing fan 150 is required to increase the heat efficiency and the drying efficiency by gradually reducing the blowing amount while turning the blowing fan to the maximum.
