And a heater 5 for heating the dry air generated by condensation in the condenser 4.

이와 더불어, 외기가 흡입되는 흡입구(6a)와, 상기 순환팬(3)과 냉각팬(8)을 동시에 구동시키는 구동모터(9)를 더 포함하여 구성된다.In addition, the inlet 6a through which the outside air is sucked and a driving motor 9 for simultaneously driving the circulation fan 3 and the cooling fan 8 are configured.

여기서, 도 1에 미설명된 참조부호 7은 상기 응축기(4)의 외기토출면과 상기 냉각팬(8)의 흡입부를 연결하는 냉각팬 덕트이다.Here, reference numeral 7, which is not described in FIG. 1, is a cooling fan duct connecting the outside air discharge surface of the condenser 4 to the suction part of the cooling fan 8.

상기와 같이 구성된 종래기술에 따른 응축식 의류건조기의 작용에 대하여 설명하면 다음과 같다.Referring to the operation of the condensation type clothes dryer according to the prior art configured as described above are as follows.

사용자가 건조대상물을 건조드럼(1) 내부에 넣고 응축식 의류건조기를 작동시키면, 히터(5)에서 가열된 고온의 공기가 상기 드럼(1) 내부로 공급되어 건조대상물에 함유된 수분을 흡수하면서 건조작용을 한다.When the user puts a drying object inside the drying drum 1 and operates the condensation type clothes dryer, the hot air heated by the heater 5 is supplied into the drum 1 to absorb the moisture contained in the drying object. It has a drying effect.

건조과정후 생성된 습공기는 필터(2)를 거쳐 보푸라기등의 이물질이 제거되고, 이물질이 제거된 습공기는 순환팬(3)으로 유입되어 응축기(4)측으로 송풍되고, 송풍된 습공기는 응축기(4)로 유입된다.The wet air generated after the drying process is removed foreign matters such as lint and the like through the filter (2), the wet air from which the foreign matters are removed is introduced into the circulation fan (3) and blown to the condenser (4) side, the blown wet air is condenser (4 Flows into).

이와 동시에, 흡입구(6a)를 통해 건조기 내부로 유입된 외기는 냉각팬(8)의 흡입력에 의해 응축기(4)로 유입되어 상기 습공기와 교차되면서 열교환을 하고, 열교환된 외기는 냉각팬(8)에 의해 강제 흡입되어 원주방향으로 강제 송풍되어 건조기 내부로 배출된 후 건조기 외부로 배출된다.At the same time, the outside air introduced into the dryer through the suction port 6a flows into the condenser 4 by the suction force of the cooling fan 8 and crosses with the wet air to exchange heat, and the exchanged outside air is the cooling fan 8 It is forcibly sucked by and forcedly blown in the circumferential direction and discharged into the dryer and then discharged to the outside of the dryer.

또한, 상기 습공기는 응축기(4)를 지나면서 열교환에 의해 응축이 일어남에 따라 건조공기로 변환되고, 변환된 건조공기는 히터(5)를 지나면서 가열되며, 가열된 고온의 건조공기는 건조드럼(1)으로 공급되어 다시 건조대상물에 건조작용을 하게 된다.In addition, the wet air is converted into dry air as condensation occurs by heat exchange while passing through the condenser (4), the converted dry air is heated through the heater (5), the heated high temperature dry air is a drying drum It is supplied to (1) and again to dry the drying object.

그러나, 상기와 같은 종래기술에 따른 응축식 의류 건조기에 있어서 건조기의 전면측에는 구조물이 많이 배치되어 있기 때문에, 상기 냉각팬(8)에 의하여 토출되는 외기와 구조물 간의 유동충돌로 인하여 유동소음이 크게 발생되는 문제점이 있었다.However, in the condensation type clothes dryer according to the prior art as described above, since many structures are disposed on the front side of the dryer, the flow noise is largely generated due to the flow collision between the air and the structure discharged by the cooling fan 8. There was a problem.

본 발명은 상기와 같은 문제점을 해결하기 위한 것으로서, 건조기 후면측 상방향으로 외기의 배출을 원활하게 유도함으로써, 건조기의 유동소음을 저감시킬 수 있는 응축식 의류 건조기용 응축기 냉각팬의 토출 유로를 제공하는데 그 목적이 있다.The present invention is to solve the above problems, by providing a discharge path of the condenser cooling fan for the condenser clothes dryer to reduce the flow noise of the dryer by smoothly inducing the discharge of the outside air to the rear side of the dryer.

도 2에 도시된 바와 같이, 본 발명에 따른 응축식 의류 건조기는 건조기 내부로 외기가 유입되도록 본체(10)의 전, 후면에 각각 형성된 전, 후면 흡입구(60a,60b)와, 상기 전, 후면 흡입구(60a,60b)를 통해 유입된 외기와 건조기 내부를 순환하는 순환공기와의 열교환 작용을 수행하는 응축기(40)와, 상기 응축기(40)에서 열교환 작용 후 배출되는 외기를 강제 흡입하여 토출하는 냉각팬(80)과, 상기 응축기(40)의 외기 토출면과 상기 냉각팬(80)의 흡입부를 연결하여 설치되는 냉각팬 덕트(70)와, 상기 냉각팬(80)으로부터 토출되는 외기가 건조기의 후면측 상방향으로 배출되도록 곡면이 형성된 외기토출유로(60c)를 포함하여 구성된다.As shown in Figure 2, the condensation type clothes dryer according to the present invention is the front, rear suction inlet (60a, 60b) formed on the front, rear of the main body 10 so that outside air flows into the dryer, and the front, rear A condenser 40 for performing heat exchange between the air introduced through the suction ports 60a and 60b and the circulating air circulating in the dryer, and forcibly sucking and discharging the outside air discharged after the heat exchange from the condenser 40. Cooling fan 80, the cooling fan duct 70 is installed by connecting the outside air discharge surface of the condenser 40 and the suction portion of the cooling fan 80, and the outdoor air discharged from the cooling fan 80 It is configured to include an external air discharge passage (60c) is formed so that the curved surface is discharged upward in the rear side.

여기서, 상기 외기토출유로(60c)에는 다공질 또는 섬유질로 형성된 흡음재가 구비되는 것이 바람직하다.Here, the outside air discharge passage (60c) is preferably provided with a sound absorbing material formed of porous or fibrous.

상기와 같이 구성된 본 발명에 따른 응축식 의류 건조기의 작용에 대하여 설명하면 다음과 같다.Referring to the operation of the condensation type clothes dryer according to the present invention configured as described above are as follows.

본 발명에 따른 응축식 의류 건조기도 상술한 종래기술에 따른 응축식 의류 건조기와 마찬가지로 건조 과정후 생성되는 습공기의 순환 과정과 응축기에서의 열교환 과정은 동일하다.Like the condensation type clothes dryer according to the prior art described above, the condensation type clothes dryer according to the present invention is the same as the circulation process of the wet air generated after the drying process and the heat exchange process in the condenser.

그러나, 본 발명에 따른 응축식 의류 건조기에 있어서, 외기는 건조기 본체(10)의 전, 후면 양측에 형성된 전, 후면 흡입구(60a,60b)를 통해 유입되기 때문에, 상기 응축기로 유입되는 외기의 유로 저항을 최소화하여 냉각팬(80)에 걸리는 정압을 저감시켜 보다 많은 외기를 응축기(40)로 유입시킨다.However, in the condensation type clothes dryer according to the present invention, the outside air flows through the front and rear suction ports 60a and 60b formed on both sides of the front and rear sides of the dryer body 10, so that the flow path of the outside air flows into the condenser. By minimizing the resistance, the static pressure applied to the cooling fan 80 is reduced to introduce more air into the condenser 40.

따라서, 상기 응축기(40)를 유동하는 습공기와 외기와의 열교환을 충분히 하여 응축기의 열교환 효율이 향상된다.Therefore, heat exchange between the humid air flowing through the condenser 40 and the outside air is sufficiently performed, thereby improving heat exchange efficiency of the condenser.

그리고, 상기 외기토출유로(60c)에는 상기 응축기(40)에서 열교환 작용 후 냉각팬(80)에 의해 토출되는 외기를 구조물이 적게 배치된 건조기 후면측 상방향으로 배출하도록 곡면이 형성되어 있기 때문에, 외기는 상기 냉각팬(80) 주위 구조물 및 건조기 내벽과의 유동충돌을 최소화하면서 건조기 외부로 배출되어 이로 이한 유동소음이 저감된다.Further, because the curved surface is formed in the outside air discharge passage 60c to discharge the outside air discharged by the cooling fan 80 after the heat exchange action from the condenser 40 upwards toward the back side of the dryer having fewer structures, The outside air is discharged to the outside of the dryer while minimizing the flow collision between the structure surrounding the cooling fan 80 and the inner wall of the dryer, thereby reducing the flow noise.

또한, 상기 외기토출유로(60c)에 다공질 또는 섬유질로 형성된 흡음재를 구비하므로써, 상기 냉각팬(80)에 의해 토출되는 외기의 유동속도를 완화하여 유동충돌을 더욱 최소화하고, 이로 인하여 유동소음을 한층 더 저감시킬 수 있다.In addition, by having a sound absorbing material formed of porous or fibrous material in the external air discharge passage (60c), by reducing the flow rate of the outdoor air discharged by the cooling fan 80 to further minimize the flow collision, thereby further increasing the flow noise Can be further reduced.

상술한 바와 같이, 본 발명은 외기토출유로에 외기가 건조기 후면측 상방향으로 배출되도록 곡면을 형성하고 흡음재를 구비하므로써, 냉각팬의 주변에 설치된 구조물 및 건조기 내벽과의 유동충돌을 최소화하면서 건조기 외부로 외기를 배출하여 유동소음이 저감되는 효과가 있다.As described above, the present invention by forming a curved surface so that the outside air is discharged to the rear side of the dryer in the air discharge flow path and provided with a sound absorbing material, the outside of the dryer while minimizing the flow collision between the structure and the inner wall of the dryer installed around the cooling fan The outside noise is emitted to reduce the flow noise.
