Description

드럼세탁기의 도어{Door for drum washing machine}Door for drum washing machine

본 발명은 드럼세탁기의 도어에 관한 것으로, 더욱 상세하게는 도어에서 세탁물과 접촉하는 면에 돌기를 형성하여 세탁물과의 기계적 마찰을 활성화시키는 것에 의하여 세탁효과를 높일 수 있도록 구성되는 드럼세탁기용 도어에 관한 것이다.The present invention relates to a door of a drum washing machine, and more particularly to a door for a drum washing machine configured to increase the washing effect by activating a mechanical friction with the laundry by forming a protrusion on the surface in contact with the laundry. It is about.

일반적인 드럼세탁기의 구성을 보이는 도 1에 도시한 바와 같이, 세탁기의 외관을 형성하는 외부케이싱(1)의 내부에는 터브(3)가 설치되어 있다. 그리고 상기 터브(3)의 내부에는 드럼(2)이 회전 가능하게 설치되어 있다. 상기 드럼(2)은 회전에 의하여 세탁물(C)의 세탁을 실질적으로 수행하는 부분이고, 상기 터브(3)는 세탁을 위하여 회전하는 드럼(2)의 회전을 안내하면서 지지하는 기능을 수행하게 되는 것으로, 그 내부 하측에는 세탁을 위한 물이 차게 된다.As shown in FIG. 1 showing the structure of a general drum washing machine, a tub 3 is provided inside the outer casing 1 forming the exterior of the washing machine. And inside the tub 3, the drum 2 is rotatably installed. The drum 2 is a portion for substantially washing the laundry (C) by the rotation, the tub (3) serves to guide and support the rotation of the rotating drum (2) for washing In this case, water for washing is filled in the lower side of the inside.

그리고 상기 드럼(2)은, 구동장치(10)에서 전달되는 동력에 의하여 회전하게 되는데, 이러한 구동장치(10)는, 모터(12)와, 상기 모터(12)에서의 동력을 전달하기 위한 벨트(14), 그리고 상기 벨트(14)가 걸린 상태로 동력을 전달받는 풀리(16), 그리고 상기 풀리의 회전에 연동하는 회전축(18) 등을 포함하고 있다. 이러한 구동장치(10)에서 발생하는 회전동력이 상기 드럼(2)에 전달되면서, 드럼이 회전하게 되고, 이러한 회전에 의하여 세탁물의 세탁이 수행되는 것이다.The drum 2 is rotated by the power transmitted from the driving device 10. The driving device 10 includes a motor 12 and a belt for transmitting power from the motor 12. 14, and a pulley 16 that receives power while the belt 14 is engaged, and a rotation shaft 18 that cooperates with the rotation of the pulley. As the rotational power generated in the driving device 10 is transmitted to the drum 2, the drum is rotated, and the laundry is washed by this rotation.

이와 같은 드럼세탁기의 전면에는 세탁물을 넣거나 꺼내기 위하여 개폐되는 도어(7)가 설치되어 있다. 일반적으로 드럼세탁기에서의 도어(7)는, 유리로 구성되어 세탁기의 동작상태를 눈으로 확인할 수 있도록 구성되고 있으며, 도어(7)의 후방으로 설치되는 도어유리(9)는 드럼(2)의 입구측으로 돌출된 상태로 설치되고 있다. 따라서 상기 드럼(2)이 회전하면서 세탁이 수행되고 있는 동안에는, 세탁물(C)은 회전하는 드럼의 내부에서 회전하게 되는 등 움직이게 되는데, 이러한 세탁물은 상기 도어유리(9)의 이면에 접촉하게 된다.The front of the drum washing machine is provided with a door 7 that opens and closes to put or take out laundry. In general, the door 7 of the drum washing machine is made of glass and configured to visually check the operating state of the washing machine, and the door glass 9 installed to the rear of the door 7 is formed of the drum 2. It is installed in a state where it protrudes toward the entrance side. Therefore, while washing is being performed while the drum 2 rotates, the laundry C moves, for example, by rotating inside the rotating drum, and the laundry comes into contact with the rear surface of the door glass 9.

세탁을 효율적으로 수행하기 위해서는, 세제와 세탁물 사이에 화학적 작용과, 세탁물의 물리적 운동 등의 조건을 만족시킬 수 있어야 한다. 세탁물의 물리적 운동에 있어서는 세탁물이 드럼 내부에서 가장 적절한 양의 마찰을 일으키는 것이 요구된다.In order to efficiently perform the washing, it is necessary to satisfy the conditions such as chemical action between the detergent and the laundry and physical movement of the laundry. The physical movement of the laundry requires that the laundry produce the most appropriate amount of friction inside the drum.

그리고 종래의 도어유리(9)의 이면은, 평면상으로 되어 있기 때문에, 실질적으로 세탁물의 물리적 운동과는 전혀 무관하다. 즉, 드럼 내부에서 세탁되는 세탁물과의 어떠한 마찰 또는 상대운동을 발생시키지 않기 때문에, 종래의 도어유리는 세탁효과와는 전혀 무관한 것임을 알 수 있다.And since the back surface of the conventional door glass 9 is planar, it has nothing to do with the physical movement of a laundry substantially. That is, since it does not generate any friction or relative movement with the laundry washed inside the drum, it can be seen that the conventional door glass has nothing to do with the washing effect.

본 발명은 목적은, 세탁이 수행되는 동안 세탁물과 접촉하는 도어의 내측부분도 이용하는 것에 의하여 보다 효율적으로 세탁을 수행할 수 있는 드럼 세탁기를 제공하는 것이다.It is an object of the present invention to provide a drum washing machine which can perform washing more efficiently by using an inner portion of a door that contacts the laundry while washing is performed.
