Description
본 고안은 드럼 세탁기용 터브의 후면 커버에 관한 것으로서, 더욱 상세하게는 드럼 세탁기를 사용할 때 터브의 후면 커버 표면이 부식되거나, 세탁물에서 발생되는 보푸라기 등이 고착되는 현상을 방지할수 있도록 한 것이다.The present invention relates to a rear cover of a tub for a drum washing machine, and more particularly, to prevent the phenomenon that the back cover surface of the tub is corroded, or lint generated from laundry when the drum washing machine is used.
일반적으로, 드럼의 회전으로 발생된 낙차에 의해 세탁되는 드럼 세탁기는 세탁, 헹굼, 탈수, 건조가 자동으로 이루어지는 세탁 및 건조 일체형과, 건조 기능이 생략된 세탁 단독형의 세탁기가 있는데, 종래의 도 1과 같은 드럼 세탁기에서 세탁시에는 터브(1)내의 드럼(3)의 회전으로 발생된 낙차를 이용하여 두드려 빠는 방식으로 세탁을 진행하게 된다.In general, a drum washing machine that is washed by a drop generated by rotation of a drum includes a washing and drying integrated type in which washing, rinsing, dehydration, and drying are automatically performed, and a washing type washing machine in which a drying function is omitted. When washing in a drum washing machine as shown in 1, washing is performed by tapping and sucking using a drop generated by the rotation of the drum 3 in the tub 1.
또한, 세탁이 완료된 세탁물을 건조시, 터브(1)의 내부로 도관을 통해 들어오는 건조한 공기는 세탁물의 수분을 흡수한 수증기로 변화하게 됨과 동시에, 원심팬의 작동에 의해 건조 히터로 이동중에 상기 터브(1)의 벽면에 콘덴싱 호스로부터 공급된 소량의 냉수에 의해 응축되어 1500W의 건조 히터에 옮겨지게 되며, 물은 배수구를 통해 배수 호스로 배출된다.In addition, when the laundry is dried, the dry air entering through the conduit into the tub 1 is changed to water vapor absorbing the water of the laundry, while the tub while moving to the drying heater by the operation of the centrifugal fan. It is condensed by a small amount of cold water supplied from the condensing hose on the wall surface of (1) and transferred to a dry heater of 1500 W, and water is discharged through the drain hole to the drain hose.
또한, 수송된 공기는 다시 건조 히터에 의해 가열되고 난 후 도관을 통해 드럼(3)의 내부로 들어가는 이와같은 과정을 반복 진행하므로써 건조가 진행되고, 완전 건조행정이 진행되는 동안 응축된 물의 배수를 하기 위해 배수 펌프는 30초 정지, 5초 작동의 방식으로 간헐적으로 작동된다.In addition, the transported air is heated again by the drying heater, and then the drying process is repeated by repeatedly entering the inside of the drum 3 through the conduit and draining the condensed water during the complete drying process. The drain pump is operated intermittently in the manner of a 30 second stop, a 5 second operation.
한편, 도 1에 나타낸 바와같이 터브(1)의 내부에는 회전가능하게 드럼(3)이 설치되고, 터브(1)내의 드럼(3) 전,후방에는 복수개의 볼(Steel Ball)(4)이 내장된 볼 밸런서(5)가 설치되어 세탁물이 한쪽으로 몰려 진동과 소음이 발생되기 전에 균형을 잡아 주어 진동과 소음을 줄여 주게 되며, 상기 드럼(1)의 전체면에는 물이 통과하기 위한 복수개의 미세한 통공(도시는 생략함)이 형성되고, 상기 터브(1)의 내의 드럼(3) 내부에는 드럼(3)의 회전시 세탁물을 들어 올려주기 위한 복수개의 리프터(6)가 설치되며, 상기 터브(1)의 후방에는 알루미늄재로 다이캐스팅된 후면 커버(2)가 장착된다.Meanwhile, as shown in FIG. 1, the drum 3 is rotatably installed inside the tub 1, and a plurality of steel balls 4 are disposed before and behind the drum 3 in the tub 1. The built-in ball balancer (5) is installed to balance the laundry before the vibration and noise is generated to one side to reduce the vibration and noise, the entire surface of the drum (1) a plurality of for passing water A fine through hole (not shown) is formed, and a plurality of lifters 6 are installed inside the drum 3 in the tub 1 to lift laundry when the drum 3 rotates. At the rear of (1), a rear cover (2) die cast of aluminum is mounted.
그러나, 이와같은 종래 드럼 세탁기의 터브(1) 후방에 장착되는 알루미늄재로 다이캐스팅된 후면 커버(2)는 사용할 때 물에 노출되어 있어서 산화 현상에 의해 표면이 쉽게 부식되므로 인해 내식성이 떨어져서 후면 커버(2)의 사용 수명이 저하되고, 후면 커버(2)의 표면에 세탁물에서 발생하는 보푸라기나, 세탁물 찌꺼기가 달라 붙어서 고착되므로 지저분해지게 되는 등의 많은 문제점이 있었다.However, the rear cover (2) die-cast with aluminum material mounted behind the tub (1) of the conventional drum washing machine is exposed to water when in use, so that the surface is easily corroded by oxidation, so the corrosion resistance is poor, so The service life of 2) is reduced, there are many problems such as lint generated from the laundry on the surface of the rear cover (2), laundry debris sticking to be stuck, and become dirty.
본 고안은 상기한 제반 문제점을 해결하기 위한 것으로서, 드럼 세탁기를 사용할 때 터브의 후방에 장착되는 후면 커버의 표면이 부식되거나, 세탁물에서 발생되는 보푸라기 등이 고착되는 현상을 방지할수 있도록 코팅 처리하여 후면 커버의 내식성을 향상시킬수 있는 드럼 세탁기용 터브의 후면 커버를 제공하는데 그 목적이 있다.The present invention is to solve the above problems, the surface of the rear cover is mounted on the rear of the tub when using the drum washing machine is coated to prevent the phenomenon that the lint, such as lint generated from the laundry is fixed to the rear It is an object of the present invention to provide a rear cover of a tub for a drum washing machine that can improve the corrosion resistance of the cover.

상기한 목적을 달성하기 위해 본 고안은 세탁수를 저장하는 드럼 세탁기용 후면 커버에 있어서, 상기한 후면 커버의 적어도 내측면에 내식성을 갖는 피막이 구비된 드럼 세탁기용 터브의 후면 커버가 제공되므로써 달성된다.In order to achieve the above object, the present invention is achieved by providing a rear cover of a drum washing machine tub having a film having a corrosion resistance on at least an inner side surface of the rear cover of the drum washing machine for storing wash water. .
이하, 본 고안을 첨부된 도면에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
도 1은 드럼 세탁기의 터브 후방에 후면 커버가 장착된 상태를 나타낸 종단면도로서, 본 고안은 드럼 세탁기의 터브(1) 후방에 장착되어 알루미늄재로 다이캐스팅된 후면 커버(2)의 표면에 내식성을 갖는 피막이 코팅 처리된다.1 is a longitudinal cross-sectional view showing a rear cover mounted on the rear of the tub of the drum washing machine, the present invention is mounted on the rear of the tub (1) of the drum washing machine, the corrosion resistance on the surface of the rear cover (2) die cast of aluminum The film which has is coated.
상기 내식성 피막은 크롬산을 바인더(Binder)로 하는 수용성 징크 프리머(Zinc Primer)액을 알루미늄재로 다이캐스팅된 후면 커버(2)의 내측면에 도포한 후 열경화(Heat Curing)에 의해 은백색의 균일한 피막을 형성하는 고성능 방청 도금을 하는 방식이다.The corrosion resistant film is coated with a water-soluble zinc primer solution containing chromic acid as a binder on the inner surface of the back cover 2, which is die-cast with aluminum, and then uniformly coated in white by heat curing. It is a method of high-performance rustproof plating to form a film.
즉, 드럼 세탁기의 터브(1) 후방에 장착되어 알루미늄재로 다이캐스팅된 후면 커버(2)의 표면에 크롬산을 바인더로 하는 수용성 징크 프리머액을 금속에 도포한 후 열경화에 의해 은백색의 균일한 피막을 형성하는 고성능 방청 도금인 내식성을 갖는 피막이 코팅되어 있으므로 드럼 세탁기를 사용할 때 물에 항상 노출되어 있는 후면 커버(2)가 산화에 의해 부식되는 현상이 발생되는 것을 방지할수 있어서 후면 커버(2)의 내식성과 사용 수명을 크게 향상시킬수 있게 된다.That is, a silver-white uniform film is coated on the surface of the rear cover 2, which is mounted behind the tub 1 of the drum washing machine and die-casted with aluminum, by applying a water-soluble zinc primer solution containing chromic acid as a binder to the metal and then thermosetting. Since the coating having a corrosion resistance, which is a high-performance rustproof plating to form a coating, can prevent corrosion of the rear cover 2, which is always exposed to water when using a drum washing machine, to prevent corrosion from occurring. Corrosion resistance and service life can be greatly improved.
또한, 후면 커버(2)의 표면에 내식성이 뛰어난 피막의 코팅됨에 따라 후면 커버(2)의 표면에 세탁물에서 발생하는 보푸라기나, 세탁물 찌꺼기가 달라 붙어서 고착됨에 따른 후면 커버(2)의 표면이 지저분해지게 되는 것을 방지할수 있게 된다.In addition, as the coating of the coating having excellent corrosion resistance on the surface of the rear cover 2, the surface of the rear cover 2 as the lint generated from the laundry on the surface of the rear cover 2 or the laundry debris stuck to the surface It can prevent it from going down.
이상에서와 같이, 본 고안은 드럼 세탁기의 터브 후방에 장착되어 알루미늄재로 다이캐스팅된 후면 커버의 내측면에 내식성을 갖는 피막이 코팅 처리되므로써 드럼 세탁기를 사용할 때 후면 커버의 표면에 산화에 의한 부식 현상이 발생되는 것을 방지할수 있어서 후면 커버의 내식성을 크게 향상시킬수 있음에 따른 사용 수명을 증대시킬수 있을 뿐만 아니라 세탁물에서 발생되는 지푸라기등이 표면에 고착되는 것을 방지할수 있으므로 인해 제품의 효율성 및 신뢰성을 대폭 향상시킨 매우 유용한 고안이다.As described above, the present invention has a corrosion-resistant coating on the inner surface of the rear cover, which is mounted on the tub rear of the drum washing machine and die-cast with aluminum, so that corrosion of the surface of the rear cover when the drum washing machine is used is prevented. It can prevent the occurrence and greatly improve the corrosion resistance of the back cover, which can increase the service life and prevent the straw generated from the laundry from sticking to the surface, which greatly improves the efficiency and reliability of the product. It is a very useful design.
