Abstract

A drying duct of a front-loading washing machine is provided to improve thermal efficiency by equally distributing heat to the air by connecting a blowing induction plate to a lower duct. A drying duct of a front-loading washing machine comprises a lower duct(10), an upper duct(20), an inlet(12), an outlet(14), a plurality of blowing induction plates(16), a heater(18), and a blower fan(22). The lower duct is connected to an outer surface of a tub. The inlet is formed at one lower part and the outlet is formed at the other lower part of the lower duct. The plural blowing induction plates are close to the inlet in the outlet direction, and convert air flow and distribute air equally when air flows from the inlet to the outlet. The heater is installed between the outlet and the blowing induction plate, and heats up air flowing in through the inlet. The lower duct, the top of which is opened, is made by injecting a poly phenylene sulfide resin. The upper duct covers the top of the lower duct. The blower fan is connected to a predetermined part corresponding to the inlet of the lower duct to introduce air through the inlet. The upper duct is also made by injecting a poly phenylene sulfide resin.

Description

드럼세탁기의 건조덕트{Drying duct in the drum type washing machine}Drying duct in the drum type washing machine

본 발명은 세탁후 세탁물이 건조되도록 히터가 내장되어 드럼 내부로 열풍을 공급하는 드럼세탁기의 건조덕트에 관한 것으로, 더욱 상세하게는 중량이 가볍고, 고온에서 잘 견디며, 절연성과 난연성 및 기계적 성질이 우수하고, 재생이 가능한 폴리페닐렌설파이드(Poly Phenylene Sulfide)수지를 사용하여 사출공정으로 제조하므로 제조공정이 간단하고, 부피가 적으며, 원가와 생산비를 절감할 수 있고, 송풍유도판을 하부덕트에 결합하여 송풍팬을 통해 유입된 공기가 상기 송풍유도판에 부딪히면서 방향이 바뀌어 고르게 분산되면서 히터 전체를 거쳐서 통과될 수 있도록 하여 히터에서 발생하는 열이 고르게 공기에 전달 되어 열 효율을 높일 수 있는 드럼세탁기의 건조덕트에 관한 것이다.The present invention relates to a drying machine of a drum washing machine for supplying hot air into a drum with a built-in heater to dry laundry after washing. More specifically, the weight is light, and it can withstand high temperatures, and has excellent insulation, flame retardancy, and mechanical properties. It is manufactured by injection process using poly Phenylene Sulfide resin which can be recycled, so the manufacturing process is simple, low volume, and cost and production cost can be reduced. Combined with the air flowing through the blowing fan hit the blowing guide plate, the direction is evenly distributed and distributed evenly through the entire heater so that the heat generated from the heater is evenly transferred to the air to increase the thermal efficiency of the washing machine It relates to the drying duct of the.

일반적으로 드럼세탁기는 세제와 세탁수 및 세탁물이 드럼 내에 투입된 상태에서 모터의 구동으로 회전하는 드럼과 세탁물의 마찰을 이용하여 세탁하는 방식으로 세탁물의 손상이 적고, 세탁물이 잘 엉키지 않으며, 두드리고 비벼빠는 효과가 있다.In general, the drum washing machine washes by using the friction of the rotating drum and the laundry driven by the motor while the detergent, the washing water, and the laundry are put into the drum, and thus the laundry is less damaged, the laundry is not tangled, and the laundry is pounded and rubbed. It works.

또한, 드럼세탁기는 세탁 기능 및 세탁이 종료된 세탁물을 건조하기 위한 건조 기능이 포함되어 있으며, 건조 과정에서 드럼 내부의 공기가 외부로 배출되는 배기식과, 드럼 내부의 공기가 외부로 배출되지 않고 세탁기 내부에서 순환되는 응축식이 있다.In addition, the drum washing machine includes a washing function and a drying function for drying the laundry after the washing is finished, an exhaust type in which air in the drum is discharged to the outside during the drying process, and the washing machine is not discharged to the outside. There is a condensation circulating inside.

상기 응축식 드럼세탁기는 건조기능을 위해 터브의 상부에 건조덕트와 응축덕트가 드럼과 연통되게 결합되며, 상기 건조덕트 내부에는 히터와 송풍팬이 결합되어 드럼 내부로 유입되는 공기를 고온으로 가열하여 드럼 내부의 세탁물을 건조시키고, 세탁물의 건조 과정에서 발생된 고온다습한 공기는 건조효율을 높이기 위해서 응축덕트를 통해 응축과정을 거치면서 저온상태로 변화되도록 한다.The condensing drum washing machine is coupled to the drying duct and the condensation duct in communication with the drum in the upper portion of the tub for the drying function, the heater and blowing fan is coupled to the inside of the drying duct to heat the air flowing into the drum to a high temperature The laundry inside the drum is dried, and the hot and humid air generated in the drying process of the drum is changed to a low temperature state through the condensation duct through the condensation duct to increase the drying efficiency.

상기 응축덕트를 통과한 공기는 상기 건조덕트 내부로 유입되어 고온 건조한 상태로 변화되며, 다시 드럼 내부로 유입되는 과정을 반복하면서 세탁물을 완전히 건조시키게 된다.The air passing through the condensation duct is introduced into the drying duct to be changed to a high temperature dry state, and the laundry is completely dried while repeating the flow into the drum.

그리고, 상기 건조덕트 내부에는 고온의 열을 발생하는 히터 장치가 내장되며, 상기 히터에 전원이 인가되면 대략 700도 정도의 열을 발생하고, 상기 건조덕트 내부의 공기는 대략 120도 안팎의 온도를 유지하게 된다.In addition, a heater device for generating high temperature heat is built in the drying duct, and when the power is applied to the heater, heat is generated about 700 degrees, and the air inside the drying duct has a temperature of about 120 degrees. Will be maintained.

따라서, 종래의 건조덕트는 고온에서도 견딜 수 있도록 금속소재인 알루미늄을 다이캐스팅하여 제조하였다.Therefore, the conventional drying duct was manufactured by die casting aluminum, which is a metal material, to withstand high temperatures.

그러나, 상기 종래의 건조덕트는 금속소재인 알루미늄을 사용하여 다이캐스팅 공법으로 제조됨으로 제조비용이 증가되고, 두께가 두꺼워지며, 중량이 많이 나 가므로 드럼세탁기의 전체 중량이 증가하는 문제점이 있었다.However, since the conventional drying duct is manufactured by a die casting method using aluminum, which is a metal material, the manufacturing cost increases, the thickness becomes thick, and the weight increases so that the overall weight of the drum washing machine increases.

또한, 종래의 건조덕트는 송풍팬을 통해 유입된 공기가 히터를 거쳐서 출구 방향으로 이동할 때 상기 송풍팬의 회전에 의해서 한쪽으로 쏠리게 되어 상기 히터의 한 부분만 거치면서 이동하게 되므로 상기 히터에서 발생하는 열이 다 전달되지 못하게 되어 열 효율이 떨어지는 문제점이 있었다.In addition, the conventional drying duct is caused to be moved to one side by the rotation of the blowing fan when the air introduced through the blowing fan moves in the exit direction through the heater, so as to move through only one part of the heater, There was a problem that the heat efficiency is lowered because the heat is not transferred.
