Description
본 발명은 드럼세탁기의 탈수제어방법에 관한 것으로써, 더욱 상세하게는 탈수행정시 사용자의 키조작에 의해 탈수행정이 일시정지된 후 다시 복귀되는 경우에 있어서의 드럼세탁기의 탈수제어방법에 관한 것이다.The present invention relates to a dehydration control method of a drum washing machine, and more particularly, to a dehydration control method of a drum washing machine in a case where the dehydration stroke is returned after being temporarily stopped by the user's key operation during the dehydration operation. .
일반적으로 드럼세탁기는 드럼형상으로 마련된 회전조의 회전으로 생긴 낙차를 이용하여 세탁물을 두드려 빠는 방식으로 빨래방망이로 두드려주는 것과 같은 효과로 세탁물의 꼬임에 의한 손상이 적은 이점이 있는 방식의 세탁기이다.In general, a drum washing machine is a washing machine having an advantage of less damage caused by twisting the laundry in the same effect as tapping the laundry by tapping the laundry using a drop generated by the rotation of the rotating tub provided in the drum shape.
이러한 드럼세탁기의 구성은 일반적으로 도 1에 도시한 바와 같이, 본체(1)의 내부에는 세탁수를 담수하는 고정조(2)가 설치되고, 고정조(2)의 내부에는 모터(4)의 구동력에 의해 회전하여 세탁과 탈수행정을 수행하는 회전조(3)가 설치된다. 회전조(3)에는 다수의 작은 구멍이 전면에 천공되어 물이 회전조(3)와 고정조(2)를 유동하도록 하며, 탈수시 세탁물에서 원심분리된 물이 고정조(2)로 이탈되도록 한다.In general, as shown in FIG. 1, the drum washing machine is provided with a fixing tank 2 for fresh water to be washed in the main body 1, and inside the fixing tank 2 of the motor 4. Rotating tank 3 is rotated by the driving force to perform washing and dehydrating stroke. The rotating tub 3 has a plurality of small holes perforated in the front to allow the water to flow through the rotating tub 3 and the fixed tub 2, so that the centrifuged water is separated from the laundry into the fixed tub 2 when dewatered. do.
한편, 이러한 구성을 갖는 드럼세탁기의 행정은 크게 세탁,헹굼 및 탈수행정으로 구분되며, 특히 탈수행정에 있어서 모터의 구동에 의해 회전조가 고속회전되어 세탁물을 탈수시키는 도중에 사용자의 키조작에 의해 탈수행정을 일시정지시킨 후 다시 탈수행정을 수행하게 되는 경우에 종래의 드럼세탁기의 탈수제어방법은 크게 두가지로 구분된다.On the other hand, the stroke of the drum washing machine having such a configuration is largely divided into washing, rinsing, and dehydrating strokes. In particular, in the dehydrating stroke, the rotating tub is rotated at a high speed by driving the motor to dehydrate the laundry by dehydrating the laundry. When the dehydration stroke is performed again after pausing, the dehydration control method of the conventional drum washing machine is largely divided into two types.
즉, 일시정지 후 다시 탈수행정이 수행될 때 세탁물의 편심량 감지없이 바로 탈수과정으로 진입하는 경우와 일시정지로 인하여 회전조가 완전정지된 후 편심감지를 다시 수행한 뒤 탈수를 진행하는 방법이다.In other words, when the dehydration administration is performed again after the temporary stop, the dehydration process immediately enters the dehydration process without detecting the eccentricity of the laundry.
그러나, 이러한 종래 드럼세탁기의 탈수제어방법에 있어서 편심감지없이 바로 진입하게 되는 경우에는 세탁물의 편심여부를 무시함으로써 편심발생시 탈수소음 및 진동이 발생되는 문제점이 있으며 또한, 회전조의 완전정지후 다시 편심감지를 수행하는 경우에는 회전조가 완전정지될 때까지 탈수가 지연되어 탈수시간이 길어지게 되는 문제점이 있었다.However, in the dehydration control method of the conventional drum washing machine, when entering immediately without eccentricity detection, there is a problem in that dehydration noise and vibration are generated when eccentricity is generated by ignoring whether the laundry is eccentric. In the case of performing the dehydration delay until the rotating tank is completely stopped, there was a problem that the dehydration time becomes longer.
따라서, 본 발명은 상기의 문제점을 해결하기 위하여 안출된 것으로써 그 목적은 탈수행정시 일시정지 후 다시 탈수가 진행되는 경우 편심감지 및 탈수시간단축을 효과적으로 수행할 수 있도록 된 드럼세탁기의 탈수제어방법을 제공하고자 하는 것이다.Therefore, the present invention has been made in order to solve the above problems, the purpose of the dehydration control method of the drum washing machine that can effectively perform eccentricity detection and dehydration time reduction when dehydration proceeds again after the temporary stop during dehydration administration Is to provide.

이러한 구성을 갖는 본 발명에 따른 드럼세탁기의 탈수제어방법을 설명하면 다음과 같다.Referring to the dehydration control method of the drum washing machine according to the present invention having such a configuration as follows.
도 3은 본 발명에 따른 드럼세탁기의 탈수제어방법을 보인 플로우차트이다. 또한 도 4a 및 도 4b는 본 발명에 따른 탈수제어방법에 있어서의 시간변화에 따른 모터회전수변화를 보인 그래프로서 도 4a는 탈수행정을 일시정지한 후 모터 회전수가 편심감지회전수이하로 떨어지기 전에 탈수행정을 재개시하는 경우를 나타낸 것이고, 도 4b 는 탈수행정을 일시정지한 후 모터 회전수가 편심감지회전수이하로 떨어진 후에 탈수행정을 재개시하는 경우의 모터 구동을 보인 것이다.3 is a flowchart illustrating a dehydration control method of a drum washing machine according to the present invention. 4A and 4B are graphs showing a change in motor rotational speed with time variation in the dehydration control method according to the present invention. FIG. 4A shows that the motor rotational speed drops below the eccentric sensing rotational speed after the dehydration stroke is paused. The case where the dehydration stroke is restarted before is shown, and FIG. 4B shows the motor driving when the dehydration stroke is restarted after the motor rotation speed drops below the eccentricity detection speed after the dehydration stroke is paused.
먼저, 본 발명에 따른 드럼세탁기의 탈수제어방법은 도 3에 도시한 플로우차트에서 보는 바와 같이 단계(s10)에서 탈수행정의 수행여부를 판단하고, 판단결과 탈수행정이면 단계(s11)에서 모터를 구동시켜 회전조를 고속회전시켜 세탁물에 함유된 수분이 고정조로 이탈되어 탈수가 수행되도록 한다.First, in the dehydration control method of the drum washing machine according to the present invention, as shown in the flowchart shown in FIG. 3, it is determined whether or not the dehydration operation is performed in step S10. By rotating the rotary bath at high speed to drive the moisture contained in the laundry is released to the fixed bath so that dehydration is performed.
한편, 모터의 구동으로 인한 탈수수행시 단계(s12)의 판단결과 사용자의 키조작에 의해 탈수행정을 일시 정지시키는 일시정지키가 입력됨이 판단되면 단계(s13)으로 진행하여 모터에 인가되는 전원을 차단하여 구동을 오프시키게 된다. 이때 모터의 구동전원이 차단됨으로 인하여 모터 및 회전조는 고속회전을 멈추고 중력에 의하여 자연정지되어 그 회전수가 하강하게 된다.On the other hand, if it is determined that the temporary stop key for stopping the dehydration operation is input by the user's key operation as a result of the determination of the step (s12) during the dehydration due to the driving of the motor, the process proceeds to the step (s13) and the power applied to the motor. To turn off the drive. At this time, since the driving power of the motor is cut off, the motor and the rotating tub stop the high speed rotation and are naturally stopped by gravity, and the rotation speed is lowered.
또한, 단계(s14)에서는 사용자가 일시정지키를 다시 선택함에 따라 탈수가 재개시됨이 판단되면 단계(s15)에서는 회전수감지부(12)를 통해 모터의 회전수를 감지하고, 감지결과 단계(s16)으로 진행하여 감지된 모터의 회전수가 편심량의 재감지를 위하여 기설정된 편심감지회전수 이하인가를 판단한다.In addition, in step S14, when it is determined that dehydration is restarted as the user selects the pause key again, in step S15, the rotation speed of the motor is sensed through the speed detection unit 12, and the detection result step ( In step s16), it is determined whether the detected rotational speed of the motor is equal to or less than the predetermined eccentric sensing rotational speed in order to detect the eccentricity again.
상기 단계(s16)의 판단결과 모터의 회전수 편심감지회전수 예컨데 고속탈수시 원심력에 의해 회전조 내벽에 붙어있던 세탁물이 떨어져 편심이 발생할 가능성이 있는 회전수인 약80rpm이하이면 단계(s17)에서 편심여부를 감지하게 된다. 이때 수행되는 편심감지는 세탁물이 한쪽으로 치우쳐 불균형으로 인한 탈수소음과 진동을 방지하기 위한 것으로써 도 4b에 도시한 바와 같이 일정 시간동안 저속 rpm으로 모터를 단속구동시키고, 이때 모터의 회전수변화를 감지하여 편심발생량을 판단한다.As a result of the determination of the step (s16), if the rotational speed of the motor eccentricity detection speed, for example, the laundry, which is attached to the inner wall of the rotating tank by the centrifugal force during the high-speed dehydration, is less than about 80 rpm, which is the rotational speed at which the eccentricity may occur. Detects eccentricity. At this time, the eccentricity detection is performed to prevent dehydration noise and vibration caused by unbalanced laundry due to one side, and as shown in FIG. 4B, the motor is intermittently driven at a low speed rpm for a predetermined time, and the rotation speed of the motor is changed. Detects the amount of eccentricity by detecting
즉, 단계(s18)에서는 모터의 회전수변화에 따른 편심발생량이 편심기준량이상이면 단계(s17)을 반복수행하여 세탁물의 불균형이 해제될 수 있도록 하고, 편심기준량이하이면 단계(s19)로 진행하여 모터를 고속회전시킴으로써 탈수를 재개시하게 된다.That is, in step s18, if the amount of eccentricity according to the rotational speed of the motor is greater than the eccentric reference amount, repeating step s17 to release the imbalance of the laundry, and if the eccentric reference amount is less, proceed to step s19. Dewatering is restarted by rotating the motor at high speed.
한편, 상기 단계(s16)의 판단결과 탈수가 재개시된 이후 감지된 모터의 회전수가 도 4a에 도시한 바와 같이 편심감지회전수이상인 경우에는 세탁물이 회전조 내벽에 그대로 붙어 있어 편심발생 가능성이 희박한 것으로 판단하여 편심감지없이 바로 단계(s19)로 진행하여 고속탈수를 수행하게 된다.On the other hand, if the rotation speed of the detected motor after the dehydration is restarted as shown in step (s16) is greater than the eccentricity detection speed as shown in FIG. The determination proceeds directly to step (s19) without detecting the eccentricity to perform a high speed dehydration.
이상에서 설명한 바와 같이, 본 발명에 따른 드럼세탁기의 탈수제어방법은 탈수행정중 사용자의 키이조작에 의해 탈수가 일시정지된 후에 다시 진행되는 경우 모터의 회전수를 감지하여 편심을 재감지한 후 고속탈수를 수행하거나 혹은 편심감지없이 바로 고속탈수를 수행하도록 한다.As described above, the dehydration control method of the drum washing machine according to the present invention detects the rotational speed of the motor when the dehydration is paused by the user's key operation during the dehydration operation, and then detects the eccentricity, Dehydration or high-speed dehydration should be performed immediately without eccentricity.
따라서, 본 발명에 따른 드럼세탁기의 탈수제어방법에 의하여 일시정지후 다시 탈수를 수행하는 경우 모터의 회전수에 따라 편심이 발생될 가능성이 있는 경우에는 편심감지 후 재탈수하고, 편심발생가능성이 없는 경우에는 바로 재탈수를 수행함으로써 편심발생에 따른 소음 및 진동발생을 방지함과 동시에 탈수시간을 단축시킬 수 있는 효과가 있다.Therefore, when dehydration is performed again after a temporary stop by the dehydration control method of the drum washing machine according to the present invention, if the eccentricity may occur according to the rotational speed of the motor, after the eccentricity detection, the dehydration is performed again and there is no possibility of eccentricity In this case, by immediately rehydrating, it is possible to prevent noise and vibration caused by eccentricity and to shorten the dehydration time.
