It is about.

종래의 기울어진 드럼세탁기는 도 1에 도시된 바와 같이 세탁수를 수용하여 세탁을 행하게 하는 외조(1)가 소정의 각도(α。)로 설치되어 있고, 상기 외조(1)의 내측에는 구동수단(3)에 의해 정·역회전하는 내조(5)가 상기 외조(1)의 기울어진 각도와 동일하게 설치되어 있으며, 상기 내조(5)의 내부에는 세탁물을 끌어 올려 낙하시킴으로써 세탁력을 높이는 리프터(7)가 설치되어 있다.As shown in FIG. 1, a conventional inclined drum washing machine is provided with an outer tub 1 for accommodating washing water to be washed at a predetermined angle α. The driving means is provided inside the tub 1. The inner tank 5, which is rotated forward and reverse by (3), is installed at the same angle as the inclined angle of the outer tank 1, and the lifter which raises the washing force by pulling up and dropping laundry inside the inner tank 5 ( 7) is installed.

상기 리프터(7)는 내조(5)면과 수평을 이루도록 동일 각도로 형성되어 있다.The lifter 7 is formed at the same angle to be horizontal to the surface of the inner tank (5).

이와 같이 구성된 종래의 기술에 의한 드럼세탁기 동작을 설명하면 다음과 같다.Referring to the drum washing machine operation according to the prior art configured as described above are as follows.

먼저, 사용자가 세탁물을 내조(7) 내부에 넣고 도시되지 않은 기능조작부를 통해 조작조건을 선택한 후 세탁기를 가동시키면 도시되지 않은 급수수단에 의해 수돗물이 상기 내조(7)의 내측으로 공급된다.First, when a user puts laundry into the inner tank 7 and selects an operating condition through a functional control unit (not shown), and then operates the washing machine, tap water is supplied into the inner tank 7 by a water supply unit (not shown).

상기 내조(7)로 소정량의 물이 공급되면 구동수단(3)이 구동되어 내조(7)를 정·역회전시키면서 세탁을 행한다.When a predetermined amount of water is supplied to the inner tank 7, the driving means 3 is driven to wash the inner tank 7 while rotating the inner tank 7 forward and reverse.

이때, 상기 내조(7)의 내부 측부에 설치된 리프터(9)에 의해 세탁물이 일정높이 까지 끌어올려지고, 상기 일정 높이에서 세탁물이 중력에 의해 내조(7)의 바닥으로 떨어지게 되므로 세탁물의 낙하에 의한 기계적인 세탁을 수행하게 된다. At this time, the laundry is pulled up to a certain height by the lifter 9 installed on the inner side of the inner tank 7, and the laundry is dropped to the bottom of the inner tank 7 by gravity at the predetermined height, thereby causing the laundry to fall. Mechanical washing is performed.

그러나, 이와 같이 구성된 종래의 드럼세탁기는 외조(1)와 내조(7)가 소정각도(α°)로 기울어져 설치되어 있어 상대적으로 내조(7)의 후방부로 세탁물(C)이 많이 몰리게 되는데, 이때, 리프터(9)가 동일각도로 형성됨에 따라 안쪽에 몰린 세탁물(C)을 텀블링이 적게 일어나 세탁력이 저하된다는 문제점이 있었다.However, in the conventional drum washing machine configured as described above, the outer tank 1 and the inner tank 7 are inclined at a predetermined angle (α °), so that the laundry C is driven to the rear portion of the inner tank 7 relatively. At this time, as the lifter 9 is formed at the same angle, there was a problem that the washing force is lowered due to less tumbling of the laundry C driven inside.

본 발명은 상기한 문제점을 해결하기 위하여 안출된 것으로서, 본 발명의 목적은 세탁조가 후방으로 하향 경사지게 설치된 경우 리프터의 후방부를 높게 형성함으로써, 세탁조의 후방부에 몰려있는 세탁물의 텀블링 작용이 충분히 확보될 수 있는 드럼세탁기의 리프터를 제공하는 데 있다.
또한, 본 발명의 다른 목적은 리프터에 다수의 돌기부를 두어 세탁물과의 마찰력을 증대시킴으로써, 리프터에 의한 세탁물의 텀블링 효과가 극대화됨과 동시에 리프터와 세탁물의 마찰 작용에 의해 세탁효과가 증대되는 드럼세탁기의 리프터를 제공하는 데 있다.The present invention has been made to solve the above problems, an object of the present invention is to form a high rear portion of the lifter when the washing tank is installed downward inclined rearward, so that the tumbling action of the laundry concentrated in the rear portion of the washing tank can be sufficiently secured. It is to provide a lifter of the drum washing machine.
In addition, another object of the present invention is to increase the friction force of the laundry by placing a plurality of projections on the lifter, maximizing the tumbling effect of the laundry by the lifter and at the same time the washing effect of the drum washing machine is increased by the friction action of the lifter To provide a lifter.

상기한 과제를 실현하기 위한 본 발명은 세탁조가 아웃케이스의 내측에서 후방으로 하향 경사지게 설치된 드럼세탁기의 리프터에 있어서, 상기 리프터는 상기 세탁조의 내측면에 전후방향으로 길게 형성되고, 상기 세탁조의 후방부에 몰린 세탁물의 텀블링 효과가 증대되도록 후방부가 전방부보다 높게 돌출 형성된 것을 특징으로 한다.
상기 리프터의 표면에는 다수의 돌기부가 돌출 형성된 것을 특징으로 한다.

The protrusions 14 are formed to be elongated in the longitudinal direction of the lifter 10 and spaced apart from each other in the protruding direction of the lifter 10.

다음은 본 발명의 일 실시 예에 의한 드럼세탁기의 리프터에 대한 작동과 작용효과를 설명한다.The following describes the operation and effect of the drum washing machine lifter according to an embodiment of the present invention.

사용자가 도시되지 않은 기능조작부를 통해 조작조건을 선택하면 급수밸브(미도시)를 통해 내조(5)의 내측으로 세탁수가 공급되고, 상기 내조(5)의 내측에 소정량의 세탁수가 공급되면 구동수단(3)에 의해 내조(5)가 정·역회전하여 세탁을 행하고, 상기 내조(5)의 내부에 설치된 상기 리프터(100)에 의해 세탁물이 일정높이 까지 끌어 올려지고, 상기 일정 높이에서 세탁물이 중력에 의해 내조(5)의 바닥으로 떨어지게 되므로 세탁물의 낙하에 의한 기계적인 세탁을 수행한다.When the user selects an operation condition through a functional control unit (not shown), the washing water is supplied into the inner tank 5 through a water supply valve (not shown), and driven when a predetermined amount of the washing water is supplied into the inner tank 5. The inner tank 5 rotates forward and reverse by the means 3 to wash the laundry, and the laundry is lifted to a certain height by the lifter 100 provided inside the inner tank 5, and the laundry is washed at the predetermined height. Since it falls to the bottom of the inner tank 5 by this gravity, mechanical washing by dropping the laundry is performed.

이때, 상기 내조(5)가 소정의 각도(α°)로 후방으로 경사지게 설치되면, 상기 내조(5)의 후방부 측으로 세탁물(C)이 쏠리게 된다.
한편, 상기 리프터(10)는 상기 내조(5)의 기울어진 방향과 반대방향으로 경사지게 돌출되므로, 상기 내조(5)의 내측면에서 전방부에 비해 후방부가 더 높게 돌출된다.
상기와 같이 다량의 세탁물과 접촉되는 리프터(10)의 후방부가 높게 돌출되면, 상기 내조(5)의 후방부에 많이 몰린 세탁물(C)이 효과적으로 텀블링되면서 상기 세탁물(C)의 세탁 성능이 향상된다. At this time, if the inner tank 5 is installed to be inclined rearward at a predetermined angle (α), the laundry (C) is leaned toward the rear side of the inner tank (5).
On the other hand, since the lifter 10 protrudes inclined in a direction opposite to the inclined direction of the inner tank 5, the rear portion protrudes higher than the front portion in the inner surface of the inner tank (5).
As described above, when the rear portion of the lifter 10 in contact with a large amount of laundry is protruded high, the laundry C concentrated in the rear portion of the inner tub 5 is effectively tumbled, and the washing performance of the laundry C is improved. .

또한, 상기 리프터(10)의 표면에 다수의 돌기부(14)가 형성됨으로써, 상기 돌기부(14)에 의해 리프터(10)와 세탁물의 마찰력이 증대된다.
상기와 같은 돌기부(14)에 의해 리프터(10)와 세탁물의 마찰력이 증대되면, 상기 세탁물은 일종의 빨래판에 빨래를 하는 효과를 얻게 되어 세탁력이 향상되고, 상기 리프터(10)에 의해 세탁물이 잘 끌어올려지게 되어 세탁물의 텀블링 효과도 향상된다.In addition, since a plurality of protrusions 14 are formed on the surface of the lifter 10, the frictional force of the lifter 10 and the laundry is increased by the protrusions 14.
When the frictional force of the lifter 10 and the laundry is increased by the protrusion 14 as described above, the laundry has an effect of washing a kind of washboard, and the washing power is improved, and the laundry is well drawn by the lifter 10. Raised, the tumbling effect of the laundry is also improved.

상술한 바와 같이 본 발명에 의한 드럼세탁기의 리프터에 의하면, 후방으로 하향 경사지게 설치된 세탁조의 내부에 리프터의 후방부가 전방부에 비해 높게 돌출되므로, 내조의 기울기로 인해 내조의 후방부 측으로 세탁물이 많이 몰리게 되더라도 리프터에 의한 세탁물의 텀블링 효과가 충분히 확보되어 세탁물의 세탁 성능이 향상되는 이점이 있다.
또한, 리프터의 표면에 다수의 돌기부가 형성됨으로써, 리프터와 세탁물의 마찰력이 증대되고, 그로 인해 세탁물의 텀블링 효과와 세탁효과가 향상되는 이점이 있다.As described above, according to the lifter of the drum washing machine according to the present invention, since the rear part of the lifter protrudes higher than the front part inside the washing tub installed inclined downwardly to the rear, the laundry is driven to the rear side of the inner tank due to the inclination of the inner tank. Even if it is enough to secure the tumbling effect of the laundry by the lifter there is an advantage that the washing performance of the laundry is improved.
In addition, since a plurality of protrusions are formed on the surface of the lifter, the frictional force between the lifter and the laundry is increased, thereby improving the tumbling effect and the washing effect of the laundry.
