응축식 의류건조기용 응축기의 냉각팬{cooling fan in condenser for condensing type clothes drier}Cooling fan in condenser for condensing type clothes drier}

본 발명은 응축식 의류건조기에 관한 것으로서, 더욱 상세하게는 응축기를 강제 냉각하기 위해 구비되는 냉각팬에 횡류팬을 적용하여 응축기의 전체 유동면에 걸쳐 외기가 균일한 유동속도로 유입될 수 있도록 한 것이다.The present invention relates to a condensation type clothes dryer, and more particularly, by applying a crossflow fan to a cooling fan provided to force-cool the condenser so that outside air can be introduced at a uniform flow rate over the entire flow surface of the condenser. will be.

일반적으로, 의류건조기는 히터에 의해 생성된 열풍을 드럼내로 송풍하여 건조대상물의 수분을 흡수하여 상기 건조대상물에 대한 건조를 행하는 기기로서, 수분을 흡수하여 건조대상물을 건조시킴에 따라 발생되는 습공기의 처리방식에 따라 크게 배기식 의류건조기와 응축식 의류건조기로 나뉘어진다.In general, a clothes dryer is a device that blows hot air generated by a heater into a drum to absorb moisture of a drying object to dry the drying object, and absorbs moisture to dry the drying object. According to the treatment method, it is divided into exhaust type clothes dryer and condensation clothes dryer.

배기식 의류건조기는 드럼으로부터 배출된 습공기를 건조기 외부로 배출하는 방식을 사용하고, 응축식 의류건조기는 드럼으로부터 배출된 습공기를 응축기에서 응축시켜 수분을 제거하고 수분이 제거된 건조공기는 다시 드럼으로 보내어 재순환시키는 방식을 사용한다.The exhaust type clothes dryer uses a method of discharging the wet air discharged from the drum to the outside of the dryer, and the condensation type clothes dryer removes moisture by condensing the wet air discharged from the drum in the condenser, and the dried air is removed from the drum. Send and recycle.

종래기술에 따른 응축식 의류건조기를 첨부된 도면을 참조하여 상세히 설명하면 다음과 같다.Referring to the condensation type clothes dryer according to the prior art in detail as follows.

도 1은 종래기술에 따른 응축식 의류건조기의 요부를 도시한 사시도이고, 도 2는 종래기술에 따른 문제점을 설명하기 위한 것으로서, 원심팬 적용시의 팬출구측에서의 공기유동속도 분포를 보여주는 구성도이다.Figure 1 is a perspective view showing the main portion of the conventional condensation type clothes dryer, Figure 2 is for explaining the problem according to the prior art, a configuration diagram showing the air flow rate distribution at the fan outlet side when applying a centrifugal fan. .

여기서, 화살표 Ⅰ은 외기의 순환유로를 나타낸 것이고, 화살표 Ⅱ는 습공기의 순환유로를 나타낸 것이며, 화살표 Ⅲ는 외기의 유동속도를 나타낸 것이다.Here, arrow I shows the circulation flow path of the outside air, arrow II shows the circulation flow path of the wet air, and arrow III shows the flow rate of the outside air.

도 1에 도시된 바와 같이, 종래기술에 따른 응축식 의류건조기는 내부에 건조대상물이 수용되는 공간부가 형성되고 내주면에 리프터(미도시)가 배치되며 구동모터(4)와 벨트(6)로 연결되어 상기 구동모터(4)의 회전력에 의해 회전하면서 건조대상물을 건조시키는 원통형의 드럼(1)과, 건조작용후 상기 드럼(1)으로부터 배출되는 습공기에 포함된 보푸라기등의 이물질을 거르는 필터(2)와, 상기 필터(2)를 거쳐 유입된 습공기에 함유된 수분을 외기와의 열교환작용에 의해 응축시켜 제거하는 응축기(3)가 포함되어 이루어진다.As shown in FIG. 1, the condensation type clothes dryer according to the related art has a space portion in which a drying object is received, and a lifter (not shown) is disposed on an inner circumferential surface thereof and is connected to the driving motor 4 and the belt 6. And a cylindrical drum (1) for drying the drying object while rotating by the rotational force of the drive motor (4), and a filter (2) for filtering foreign matter such as lint or dust contained in the wet air discharged from the drum (1) after the drying operation. ), And a condenser (3) for condensing and removing water contained in the wet air introduced through the filter (2) by heat exchange with the outside air.

이와 더불어, 상기 응축기(3)에서 습공기와의 열교환작용을 통해 응축이 이루어지도록 축방향으로 흡입된 외기를 상기 응축기(3)와 연결되는 덕트(8)를 통해 원주방향으로 토출하여 상기 응축기(3)로 보내는 원심팬(7a)과, 상기 응축기(3)를 거쳐 생성된 건조공기를 드럼(1)으로 보내는 송풍팬(5)과, 상기 송풍팬(5)에 의해 송풍된 건조공기를 드럼에 유입되기 전에 가열하는 히터(미도시)를 더 포함하여 구성된다.In addition, the condenser (3) is discharged in the circumferential direction through the duct (8) connected to the condenser (3) to the outside air sucked in the axial direction to achieve condensation through heat exchange action with the wet air in the condenser (3) Centrifugal fan (7a) to be sent to), a blowing fan (5) for sending dry air generated through the condenser (3) to the drum (1), and dry air blown by the blower fan (5) to the drum It is configured to further include a heater (not shown) for heating before being introduced.

상기에서 원심팬(7a)은 원심팬 케이스(7b)에 내장된다.The centrifugal fan 7a is built in the centrifugal fan case 7b.

그러나, 상기와 같이 구성된 종래 의류건조기에 있어서는 응축기(3)에서의 열교환이 원활하게 이루어지지 않는 문제점이 있었다.However, in the conventional clothes dryer configured as described above, there was a problem that heat exchange in the condenser 3 was not performed smoothly.

즉, 도 2에 도시된 바와 같이, 상기 원심팬(7a)의 외기토출폭(A)은 상기 응축기(3)의 외기유입폭(B)보다 작기 때문에, 상기 응축기(3)로 외기가 유입되는 중심부에서는 외기의 유동속도가 크고 유동량이 많은 반면 상기 응축기(3)로 외기가 유입되는 외곽부로 갈수록 유동속도와 유동량이 작아지게 되고, 특히 응축기 양측외곽부분에는 외기의 유동량이 거의 없는 영역(dead zone)이 발생하게 된다.That is, as shown in Figure 2, the outside air discharge width (A) of the centrifugal fan (7a) is smaller than the outside air inlet width (B) of the condenser 3, the outside air flows into the condenser (3) In the center, the flow rate of the outside air is large and the flow rate is large, while the flow rate and the flow amount decrease as the outside air is introduced into the condenser (3). ) Will occur.

따라서, 상기 응축기(3)로 유입되는 외기의 유동속도 및 유동량의 편차에 기인해 상기 응축기(3)에서의 열교환이 응축기(3) 전면(全面)에 걸쳐 고르게 이루어지지 못하게 되어 응축기(3)의 전체적인 열교환 효율이 떨어지게 됨으로써, 응축식 의류건조기의 건조성능 또한 함께 저하되는 문제점이 있었다.Therefore, the heat exchange in the condenser 3 is not evenly distributed over the entire surface of the condenser 3 due to the variation in the flow rate and the flow amount of the outside air flowing into the condenser 3. As the overall heat exchange efficiency is lowered, there is a problem that the drying performance of the condensation type clothes dryer is also reduced.

본 발명은 상기와 같은 문제점을 해결하기 위한 것으로서, 응축기를 강제 냉각하기 위한 냉각팬으로서 횡류팬을 적용하여, 냉각팬에서 토출된 외기가 균일한 유동속도를 가지고 상기 응축기로 유입되도록 함으로써 응축기의 열교환 효율을 향상시키고, 나아가 의류건조기의 전체적인 건조성능을 함께 향상시킬 수 있도록 한 응축식 의류건조기를 제공하는데 그 목적이 있다.The present invention is to solve the above problems, by applying a cross-flow fan as a cooling fan for forcibly cooling the condenser, by allowing the outside air discharged from the cooling fan to flow into the condenser with a uniform flow rate An object of the present invention is to provide a condensation type clothes dryer that can improve the efficiency and further improve the overall drying performance of the clothes dryer.

도 3은 본 발명에 따른 응축식 의류건조기의 요부를 도시한 사시도이고, 도 4는 본 발명 횡류팬 적용시의 팬출구측에서의 공기유동속도 분포를 보여주는 구성도이다.Figure 3 is a perspective view showing the main part of the condensation type clothes dryer according to the present invention, Figure 4 is a block diagram showing the air flow rate distribution at the fan outlet side when the present invention cross flow fan.

도 3에 도시된 바와 같이, 본 발명에 따른 응축식 의류건조기는 내부에 세탁물이 수용되고 내주면에 리프터(미도시)가 배치되며 구동모터(40)와 벨트(60)로 연결되어 상기 구동모터(40)의 회전력에 의해 회전하면서 세탁물을 건조시키는 원통형의 드럼(10)과, 건조작용후 상기 드럼(10)으로부터 배출되는 습공기에 포함된 보푸라기등의 이물질을 거르는 필터(20)와, 상기 필터(20)를 거쳐 유입된 습공기에 함유된 수분을 외기와의 열교환작용에 의해 응축시켜 제거하는 응축기(30)가 포함되어 이루어진다.As shown in FIG. 3, the condensation type clothes dryer according to the present invention has laundry contained therein and a lifter (not shown) disposed on an inner circumferential surface thereof, and is connected to a driving motor 40 and a belt 60 so that the driving motor ( A cylindrical drum 10 for drying the laundry while rotating by the rotational force of 40, a filter 20 for filtering foreign matters such as lint and the like contained in the wet air discharged from the drum 10 after the drying operation, and the filter ( It comprises a condenser 30 for condensing and removing the water contained in the wet air introduced through 20) by the heat exchange action with the outside air.

이와 더불어, 상기 응축기(30)에서의 열교환작용을 위하여 외기를 흡입하여 응축기(30)측으로 토출하는 횡류팬(70a)과, 상기 응축기(30)를 거쳐 생성된 건조공기를 드럼(10)으로 보내는 송풍팬(50)과, 상기 송풍팬(50)에 의해 송풍된 건조공기를 드럼(10)에 유입되기 전에 가열하는 히터(미도시)가 더 포함되어 구성됨이 바람직하다.In addition, the cross-flow fan 70a for sucking the outside air and discharging it to the condenser 30 for the heat exchange effect in the condenser 30 and sending the dry air generated through the condenser 30 to the drum 10. Blowing fan 50 and a heater (not shown) for heating the drying air blown by the blower fan 50 before entering the drum 10 is preferably configured to further include.

이 때, 상기 횡류팬(70a)은 횡류팬 케이스(70b)에 내장된다.At this time, the cross flow fan 70a is built in the cross flow fan case 70b.

또한, 상기 횡류팬 케이스는 팬의 상측에서 외기가 유입되어 팬 측면으로 배출되도록 설치된다.In addition, the cross flow fan case is installed so that outside air flows in from the upper side of the fan and discharges to the side of the fan.

그리고, 도 4에 도시된 바와 같이, 상기 횡류팬(70a)의 외기토출폭(A′)은 상기 응축기(30)의 외기유입폭(B)과 동일한 폭을 갖도록 형성된다.And, as shown in Figure 4, the outside air discharge width (A ') of the cross flow fan (70a) is formed to have the same width as the outside air inlet width (B) of the condenser (30).

즉, 상기 원심팬(7a) 출구측과 응축기(30) 입구측은 덕트(80)로 연결되며, 상기 덕트(80)의 유로 단면적은 일정하다.That is, the outlet side of the centrifugal fan 7a and the inlet side of the condenser 30 are connected to the duct 80, and the flow path cross-sectional area of the duct 80 is constant.

이와 같이 구성된 본 발명 의류건조기에 있어서의 작용은 다음과 같다.The operation in the clothes dryer of the present invention configured as described above is as follows.

본 발명의 응축식 의류건조기 역시, 드럼(10)으로부터 배출된 습공기를 응축기(30)에서 응축시켜 수분을 제거하고 수분이 제거된 건조공기는 다시 드럼(10)으로 보내어 재순환시키는 방식을 사용하여 건조대상물을 건조시킴은 전술한 종래기술에서와 마찬가지이다.The condensation type clothes dryer of the present invention also removes moisture by condensing the humid air discharged from the drum 10 in the condenser 30, and the dried air, which has been removed, is dried again by sending it to the drum 10 for recycling. Drying the object is the same as in the prior art described above.

그러나, 본 발명에서는 응축기(30)에서 습공기의 수분을 응축시켜 제거함에 있어, 상기 응축기(30)로 외기를 보내어 응축기(30)에서 습공기와의 열교환이 이루어지도록 할 때, 냉각팬으로서 원심팬(7a:도 1참조)이 아닌 횡류팬(70a)이 적용됨으로써 냉각팬으로부터 토출되어 상기 응축기(30)로 유입되는 외기의 유동속도 분포가 종래와는 달라지게 된다.However, in the present invention, in condensing and removing the moisture of the wet air in the condenser 30, when the outside air is sent to the condenser 30 so that the heat exchange with the wet air in the condenser 30, the centrifugal fan ( 7a: the crossflow fan 70a (not shown in FIG. 1) is applied, so that the flow rate distribution of the outside air discharged from the cooling fan and introduced into the condenser 30 is different from the conventional one.

즉, 도 4에 도시된 바와 같이 횡류팬(70a)의 외기토출폭(A′)은 상기 응축기(30)의 외기유입폭(B)과 동일한 폭을 갖도록 형성되며, 상기 횡류팬(70a) 출구측과 응축기(30) 입구측은 길이방향을 따라 동일한 유로 단면적을 갖는 덕트(80)로 연결된다.That is, as shown in FIG. 4, the outside air discharge width A ′ of the cross flow fan 70a is formed to have the same width as the outside air inflow width B of the condenser 30, and the outlet of the cross flow fan 70a is discharged. The side and the inlet side of the condenser 30 are connected to the duct 80 having the same flow path cross-sectional area along the longitudinal direction.

따라서, 상기 횡류팬(70a)으로부터 토출되어 상기 응축기(30)로 유입되는 외기는 응축기(30)의 전(全) 유동면에 걸쳐 균일한 속도분포를 가지며 유동하게 되고, 이에 따라 본 발명이 적용된 의류건조기에서는 응축기(30) 중심부와 외곽부에서의 유동속도 차이가 없어져, 종래와는 달리 응축기(30) 외곽부에 데드존(dead zone)이 형성되는 현상은 발생하지 않는다.Therefore, the outside air discharged from the crossflow fan 70a and introduced into the condenser 30 flows with a uniform velocity distribution over the entire flow surface of the condenser 30, and thus the present invention is applied. In the clothes dryer, there is no difference in flow velocity between the center and the outer portion of the condenser 30, so that a phenomenon in which a dead zone is formed on the outer side of the condenser 30 unlike the conventional art does not occur.

그리고, 상기한 바와 같이 데드 존 발생이 해소됨으로 인하여, 외기와 접촉하여 냉각되는 응축기(30) 표면적이 늘어나게 되며, 이는 응축기(30) 표면에서의 습공기와의 실제 열교환 면적이 증대되는 결과로 이어짐으로써, 상기 응축기(30)에서의 열교환 효율을 향상시키게 되며, 이는 결국 응축식 의류건조기의 전체적인 건조성능 역시 향상시키게 되는 것이다.As the dead zone is eliminated as described above, the surface area of the condenser 30 cooled in contact with the outside air is increased, which leads to an increase in the actual heat exchange area with the humid air on the surface of the condenser 30. In this case, the heat exchange efficiency of the condenser 30 is improved, which in turn improves the overall drying performance of the condensation type clothes dryer.

상술한 바와 같이, 본 발명은 응축기를 강제냉각하기 위해 구비되는 냉각팬에 상기 응축기의 외기유입폭과 동일한 폭으로 외기를 토출할 수 있도록 횡류팬을 적용하므로서, 상기 횡류팬으로부터 토출되는 외기가 균일한 유동속도로 상기 응축기로 유입될 수 있도록 하여 상기 응축기의 열교환 효율을 향상시키고, 이로 인하여 응축식 의류건조기의 전체적인 건조성능을 향상시키는 효과가 있다.As described above, the present invention is applied to the cooling fan provided to forcibly cooling the condenser, by applying a cross flow fan to discharge the outside air in the same width as the outside air inlet width of the condenser, the outside air discharged from the cross flow fan is uniform It can be introduced into the condenser at a flow rate to improve the heat exchange efficiency of the condenser, thereby improving the overall drying performance of the condensation type clothes dryer.
