본 발명은 기울어진 세탁기의 배수 및 탈수 운전 제어 방법에 관한 것으로서, 특히 탈수 운전이 시작되기 전인 배수 운전 과정에서 세탁 수위에 따라 세탁조의 배수회전속도를 다르게 설정함으로써 최적의 배수 작동 및 탈수 운전이 이루어질 수 있도록 기울어진 세탁기의 회전 배수 제어 방법에 관한 것이다.The present invention relates to a method for controlling drainage and dehydration operation of an inclined washing machine. In particular, an optimal drainage operation and dehydration operation are performed by differently setting the rotation speed of the washing tank according to the washing water level in the drainage operation process before the dehydration operation starts. It relates to a rotating drain control method of the washing machine tilted to be.

도 1은 기울어진 세탁기의 내부 구성도이다.1 is an internal configuration diagram of a tilted washing machine.

기울어진 세탁기는 저수조(11)와 세탁조(15)가 중력이 작용하는 방향에 대하여 일정 각도만큼 기울어지게 위치됨으로써 세탁조(15) 내에 복잡한 수류를 생성하여 세탁물의 세정력을 향상시킬 수 있고, 앞쪽을 상대적으로 낮게 구성함으로써 사용자가 세탁물을 넣고 빼는 작업이 용이해질 수 있도록 구성된 세탁기이다.The inclined washing machine may be positioned at an angle with respect to the direction in which gravity acts on the water storage tank 11 and the washing tank 15 to generate complex water flow in the washing tank 15 to improve washing power of the laundry, and the front side may be relatively The washing machine is configured so that the user can easily put in and take out the laundry.

이와 같이 기울어진 세탁기는 외곽을 형성하는 케이스(1)와, 상기 케이스(1) 내에 수직 방향에 대하여 일정 각도(θ)만큼 기울어지게 위치되어 내부에서 세탁물의 세정이 이루어지는 저수조(11) 및 세탁조(15)와, 상기 저수조(11)를 케이스(1) 내에 기울어진 상태로 지지하는 다수의 걸이 부재(20)로 구성된다.The washing machine inclined as described above is positioned in an inclined case 1 and an inclined angle (θ) with respect to the vertical direction in the case 1, and the washing tank 11 and the washing tank in which the washing of the laundry is performed therein. 15) and a plurality of hanger members 20 for supporting the reservoir 11 in an inclined state in the case 1.

상기 저수조(11)는 상기 걸이부재(20)를 통해 케이스(1) 내에 지지되어 내부에 세탁수가 저장되는 통이고, 상기 세탁조(15)는 상기 저수조(11)에 내장되어 세탁물이 세정되는 통으로 세탁수가 통과할 수 있도록 다수의 홀이 형성된다.The reservoir 11 is a tub that is supported in the case 1 through the hook member 20 to store the washing water therein, and the laundry tub 15 is embedded in the reservoir 11 to wash the laundry. Multiple holes are formed to allow water to pass through.

그리고 상기 저수조(11)의 하부에는 상기 세탁조(15) 또는 펄세이터(16)를 회전 구동하기 위한 구동 모터(30)가 설치되고, 세탁수 및 헹굼수를 케이스(1) 밖 으로 배출할 수 있도록 배수 호스(40) 및 배수 밸브(45)가 구비된다.In addition, a lower part of the water storage tank 11 is provided with a drive motor 30 for rotationally driving the washing tank 15 or the pulsator 16 so that the washing water and the rinsing water can be discharged out of the case 1. A drain hose 40 and a drain valve 45 are provided.

도 2와 도 3은 상기와 같은 기울어진 세탁기에서 종래 기술에 따른 배수 및 탈수 제어 방법이 도시된 순서도 및 개략적인 작동 상태도이다.2 and 3 are a flow chart and a schematic operational state diagram showing a drainage and dewatering control method according to the prior art in the inclined washing machine.

이와 같이 기울어진 세탁기는 상기 세탁조(15)에 세탁물 및 세제가 투입된 상태에서 세탁수가 공급되면 구동 모터(30)가 동작되어 상기 펄세이터(16) 또는 세탁조(15)가 회전되면서 세탁 운전이 실시된다.(도 3의 (a) 참조)When the washing machine is inclined as described above, when washing water is supplied in a state in which laundry and detergent are put into the washing tank 15, the driving motor 30 is operated to perform the washing operation while the pulsator 16 or the washing tank 15 is rotated. (See Fig. 3 (a).)

이와 같이 세탁 운전이 완료된 다음 일정시간이 경과되면 상기 구동 모터(30)가 동작을 멈추고, 상기 배수 밸브(45)가 개방되면서 상기 저수조(11) 내부의 물이 배수 호스(40)를 통하여 외부로 자연 배수된다.(도 3의 (b) 참조)In this manner, when a predetermined time elapses after the washing operation is completed, the driving motor 30 stops the operation, and the drain valve 45 is opened, and the water in the reservoir 11 is transferred to the outside through the drain hose 40. Natural drainage (see Figure 3 (b)).

상기와 같이 배수가 완료되면, 저수조(11) 내에 잔수가 완전히 배출되도록 일정 시간 대기 상태가 진행되고, 이때, 세탁조(15) 내부의 세탁물은 중력에 의해 상대적으로 낮은 앞쪽 바닥에 쏠려 있게 된다.(도 3의 (c) 참조)When the drainage is completed as described above, the standby state is performed for a predetermined time so that the remaining water is completely discharged into the reservoir 11, and at this time, the laundry inside the washing tank 15 is concentrated on the relatively low front floor by gravity. (C) of FIG. 3)

이와 같은 상태에서 구동 모터(30)가 다시 작동되면서 상기 세탁조(15)가 고속으로 회전되어 세탁물에 포함된 수분을 제거하기 위한 탈수 운전이 진행된다. In this state, as the driving motor 30 is operated again, the washing tank 15 is rotated at a high speed so that a dehydration operation for removing water contained in the laundry is performed.

이후, 세탁조(15)에 다시 물이 공급되어 일정높이까지 차 오르게 되면서 헹굼 운전이 실시되는데, 헹굼 운전은 탈수 운전과 함께 보통 2 ~ 3회에 걸쳐 이루어진다.Thereafter, the washing tank 15 is supplied with water again to rise up to a certain height while the rinsing operation is performed. The rinsing operation is usually performed two to three times together with the dehydration operation.

상기와 같이 헹굼 운전이 완료되면, 다시 마지막 배수 및 탈수 운전이 진행된 다음 세탁기의 작동이 끝나게 된다.When the rinsing operation is completed as described above, the last drain and dehydration operation is performed again, the operation of the washing machine is finished.

그러나, 상기와 같은 종래 기술의 기울어진 세탁기의 배수와 탈수 제어 방법 은 배수가 완료되면 유체 밸런스(18) 내의 유체와 세탁조(15) 내의 세탁물이 중력에 의해 상대적으로 낮은 앞쪽에 편중된 언밸런스 상태에서 세탁조(15)가 고속으로 회전되면서 탈수 작동이 이루어지기 때문에 탈수 작동 작동시에 세탁조(15)는 물론 저수조(11)가 크게 요동하게 되어 정상적인 탈수 작동이 불가능해질 수 있는 문제점이 있다.However, the drainage and dewatering control method of the inclined washing machine according to the prior art as described above, in the unbalanced state in which the fluid in the fluid balance 18 and the laundry in the washing tank 15 are biased relatively low by gravity when draining is completed. Since the washing tank 15 rotates at a high speed, the dehydration operation is performed, and thus, the washing tank 15 as well as the storage tank 11 are greatly shaken during the dehydration operation, so that the normal dewatering operation may be impossible.

본 발명은 상기한 문제점을 해결하기 위하여 안출된 것으로서, 세탁 수위에 따라 적절한 회전 속도로 세탁조가 회전되면서 배수 운전이 이루어지도록 함으로써 최적의 회전 배수 작동이 이루어짐과 아울러 세탁조의 언밸런스를 최소화한 상태에서 탈수 운전이 시작되도록 하는 기울어진 세탁기의 회전 배수 제어 방법을 제공하는 데 있다.The present invention has been made in order to solve the above problems, by performing the drainage operation while the washing tank is rotated at an appropriate rotational speed according to the washing water level to achieve the optimum rotational drainage operation and dehydration in the state to minimize the unbalance of the washing tank It is to provide a rotational drainage control method of a tilted washing machine to start the operation.

상기한 과제를 실현하기 위한 본 발명에 따른 기울어진 세탁기의 회전 배수 제어 방법은, 세탁 및 헹굼 작동이 완료되면, 세탁조 내의 세탁 수위를 감지하여 배수 회전속도를 결정하는 배수회전속도 결정단계와; 상기 배수회전속도 결정단계에서 결정된 배수 회전속도에 따라 세탁조를 회전시키면서 세탁수를 배수하는 회전 배수 단계를 포함한 것을 특징으로 하여 가능하게 된다.Rotating drainage control method of the inclined washing machine according to the present invention for realizing the above object, the washing and rinsing operation is completed, the drainage rotation speed determining step of determining the rotational speed by detecting the washing water level in the washing tank; It is possible to characterized in that it comprises a rotary drainage step of draining the washing water while rotating the washing tank according to the drainage rotation speed determined in the drainage rotation speed determining step.

상기에서 배수 회전 속도는 세탁물에 작용하는 중력 가속도를 극복하는 최소분산회전속도 보다는 크고, 각 세탁 수위에서 발생하는 공진 회전속도(주파수)보다는 작게 설정된다.
In the above, the drainage rotational speed is set higher than the minimum dispersion rotational speed to overcome the gravity acceleration acting on the laundry and smaller than the resonance rotational speed (frequency) generated at each washing level.

이하, 첨부된 도면을 참조하여 본 발명의 실시 예를 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

도 4는 본 발명에 따른 회전 배수 제어 방법이 포함된 기울어진 세탁기의 배수 및 탈수 제어방법이 도시된 순서도이고, 도 5는 본 발명에 따른 배수 및 탈수 제어 방법이 도시된 작동 상태도이다.4 is a flowchart illustrating a drainage and dewatering control method of an inclined washing machine including a rotational drainage control method according to the present invention, and FIG. 5 is an operational state diagram illustrating the drainage and dewatering control method according to the present invention.

도 4 및 도 5를 참고하면, 도 5의 (a)에서와 같이 세탁조가 좌우 구동되는 세탁 및 헹굼 작동이 완료되면(S1), 세탁조 내의 세탁포량 즉, 세탁 수위를 감지하여 배수 회전속도를 결정하는 배수회전속도 결정단계(S2)와, 도 5의 (b)에서와 같이 배수 밸브(70)가 개방되는 동시에 구동 모터(55)가 작동되면서 상기 결정 배수 회전속도(rpm)까지 세탁조(65)의 회전 속도를 상승시키면서 배수 호스(75)를 통해 세탁수를 배수하는 회전 배수 단계(S3)와, 상기 회전 배수 단계(S3)를 통해 세탁수의 배수가 완료되면 도 5의 (c)에서와 같이 구동 모터(55)의 작동으로 일정 회전 속도 이상으로 세탁조(65)가 고속 회전되면서 세탁물에 포함된 수분을 탈수하는 탈수 작동 단계(S4)로 구성된다.4 and 5, when the washing and rinsing operation in which the washing tank is driven left and right as shown in (a) of FIG. 5 is completed (S 1 ), the amount of the washing cloth in the washing tank, that is, the washing water level, is sensed to increase the drainage rotational speed. To determine the drainage rotation speed determining step (S 2 ), and as shown in (b) of Figure 5, the drainage valve 70 is opened and the drive motor 55 is operated while the washing water tank (rpm) to the determined drainage rotational speed (rpm) Rotational drainage step S 3 for draining the wash water through the drain hose 75 while increasing the rotational speed of 65, and when the drainage of the wash water is completed through the rotational drainage step S 3 , FIG. As in c), the washing tank 65 is rotated at a high speed by the operation of the driving motor 55 at a higher rotational speed, and the dehydration operation step S 4 is used to dehydrate water contained in the laundry.

상기에서 세탁조의 수위 감지는 통상적으로 세탁기에 적용되는 수위 감지 센서를 통해 감지하게 된다.The water level detection of the washing tank is typically detected through a water level sensor applied to the washing machine.

도 6은 본 발명에 따른 각 수위별 회전 배수 속도를 결정하는 참고 그래프이다. 6 is a reference graph for determining the rotational drainage speed for each level according to the present invention.                     

도 6을 참조하면, 상기 배수회전속도 결정단계(S2)에서 결정되는 배수회전속도(

Figure 112000014790162-pat00001
)는 세탁조 내의 세탁 수위가 커질수록 최소한 같거나 점차 커지도록 설정된다.Referring to Figure 6, the drainage speed determined in the drainage speed determining step (S 2 ) (
Figure 112000014790162-pat00001
) Is set to be at least equal to or larger as the washing level in the washing tank increases.

즉, 세탁 수위가 커질수록 최초로 발생되는 공진 주파수 즉, 공진 회전 속도(

Figure 112000014790162-pat00002
)도 일반적으로 커지게 되므로 배수회전속도(
Figure 112000014790162-pat00003
)도 세탁 수위에 따라 같거나 점차 커지게 설정되는 것이다.In other words, as the washing level increases, the resonance frequency generated first, that is, the resonance rotation speed (
Figure 112000014790162-pat00002
) Is also generally larger, so drain rotation speed (
Figure 112000014790162-pat00003
) Is also set equal to or larger depending on the washing level.

특히, 세탁 수위에 따른 최적의 배수회전속도(

Figure 112000014790162-pat00004
)는 세탁물에 작용하는 중력 가속도를 극복하는 최소 분산회전속도(
Figure 112000014790162-pat00005
) 보다는 크고, 각 세탁 수위에서 발생하는 공진 회전속도(주파수)(
Figure 112000014790162-pat00006
)보다는 작게 설정되는 것이 바람직하다.In particular, the optimum drainage speed according to the washing level (
Figure 112000014790162-pat00004
) Is the minimum dispersion rotational speed (C) that overcomes the acceleration of gravity on the laundry.
Figure 112000014790162-pat00005
Greater than) and the resonant rotational speed (frequency) at each wash level (
Figure 112000014790162-pat00006
It is preferable to set smaller than).

즉, 세탁기의 수위를 '고', '중', '저', '소' 로 구분한다면, 세탁 수위에 따라 최적의 배수회전속도(

Figure 112000014790162-pat00007
)를 산출하는 과정은, That is, if the water level of the washing machine is divided into 'high', 'medium', 'low' and 'small', the optimum drainage speed (
Figure 112000014790162-pat00007
), The process of calculating

여기서, 상기 최소 분산회전속도(

Figure 112000014790162-pat00014
) 값은 세탁물이 중력 가속도를 이기고 세탁조의 벽면 방향으로 이동할 수 있는 회전 속도로서, 도 5(b)를 참조한 하기의 수식에 의해 구할 수 있다.Here, the minimum dispersion rotation speed (
Figure 112000014790162-pat00014
) Value is a rotational speed at which the laundry can move in the direction of the wall of the washing tank to overcome the acceleration of gravity, and can be obtained by the following formula with reference to FIG. 5 (b).

Figure 112000014790162-pat00015
Figure 112000014790162-pat00015

상기에서

Figure 112000014790162-pat00017
는 중력 가속도,
Figure 112000014790162-pat00018
는 세탁조의 회전 반경이다.From above
Figure 112000014790162-pat00017
Is the acceleration of gravity,
Figure 112000014790162-pat00018
Is the turning radius of the washing tub.

따라서, 세탁수위별 최적의 배수회전속도(

Figure 112000014790162-pat00019
)는 도 6에서와 같이 최소 분산회전속도(
Figure 112000014790162-pat00020
)와 수위별 공진 회전속도(
Figure 112000014790162-pat00021
) 사이의 영역에서 설정된다.Therefore, the optimum drainage speed for each wash level (
Figure 112000014790162-pat00019
) Is the minimum distributed rotational speed (
Figure 112000014790162-pat00020
) And Resonant Rotational Speed by Water Level (
Figure 112000014790162-pat00021
) Is set in the area between.

상기와 같은 본 발명에 따른 기울어진 세탁기의 회전 배수 제어 방법은 세탁물의 양에 따라 최적의 배수회전속도(
