Description
본 발명은 세탁기의 탈수 운전방법에 관한 것으로, 특히 세탁기를 저속 및 고속으로 운전시켜, 각기 검출한 UB위치와 UB량을 비교하고, 그 비교결과에 근거하여 탈수가 진행되면서 UB양의 변동을 예측하여 포고름을 재실행함으로써, 탈수시 발생하는 과도한 진동을 미연에 방지하도록 한 세탁기의 탈수운전방법에 관한 것이다.The present invention relates to a dehydration operation method of a washing machine. In particular, the washing machine is operated at a low speed and a high speed to compare the detected UB positions and the amount of UB, respectively, and predict the change in the amount of UB while the dehydration proceeds based on the comparison result. The present invention relates to a washing machine dehydration operation method for preventing excessive vibration generated during dehydration by re-running the pore.
일반적으로, 세탁기는 때가 묻은 의류를 세탁액 속에 넣으면 세제의 화학 작용으로 섬유에서 때가 떨어지지만 세제만으로는 시간이 오래 걸리고 섬유가 손상될 수 있으므로 세탁액 속에 담겨진 섬유에 적당한 마찰이나 진동 등의 기계적 작용을 가하여 세탁 속도를 향상시키기 위한 목적으로 사용된다. In general, a washing machine puts soiled clothing into a laundry solution and the chemicals of the detergent remove the dirt from the fiber, but the detergent alone takes a long time and the fibers may be damaged. Therefore, the washing machine may have a mechanical action such as friction or vibration on the fiber contained in the laundry solution. In addition, it is used for the purpose of improving the washing speed.
도 1은 종래 기술에 따른 세타기의 탈수 운전방법에 대한 동작흐름도이고, 도2는 종래 기술에 따른 세탁기의 탈수 운전방법의 시간에 따른 속도(RPM)가 도시된 그래프이다. 1 is a flowchart illustrating a dehydration operation method of the theta according to the prior art, and FIG. 2 is a graph illustrating a speed (RPM) with time of the dewatering operation method of the washing machine according to the prior art.
일반적으로 세탁기의 탈수 기능은 포풀림 수행 후에 세탁물을 골고루 펴주는 포고름을 거쳐 UB량(편심량:이하, UB라함)을 감지하게 된다. 그리고, 그 UB 감지 결과에 따라 세탁 기능을 정지시키거나, 세탁 기능을 더욱 가속하여 본탈수에 들어가게 된다. In general, the dehydration function of the washing machine detects the amount of UB (Eccentricity: UB, UB) through the pore that evenly spreads the laundry after performing the inflation. Then, depending on the UB detection result, the washing function is stopped or the washing function is further accelerated to enter the main dehydration.
여기서, 상기 UB량을 감지하기 위한 방법을 도 1 및 도 2를 참조하여 설명하면, 탈수모드로 전환되면 세탁기를 일정 저속으로 구동시켜 세탁물이 들어 있는 드럼(미도시)의 회전 속도를 가속시키고, 그 상태를 유지하게 된다(S1).Here, the method for detecting the UB amount will be described with reference to FIGS. 1 and 2, when the dehydration mode is switched, the washing machine is driven at a constant low speed to accelerate the rotation speed of a drum (not shown) containing laundry, The state is maintained (S1).
그 다음, 드럼내에 세탁물이 한쪽으로 치우쳐 있어 전체적으로 어느 정도 기울어졌는지를 UB량을 통해 감지하게 된다(S2). Then, the laundry in the drum is biased to one side to detect how much the overall tilted through the amount of UB (S2).
그 다음, 상기 UB량이 시스템에서 허용될 수 있는 값, 즉 기준UB량 이상인지를 판단하게 된다.(S3)Then, it is determined whether the amount of UB is a value that is acceptable in the system, that is, the reference UB amount or more (S3).
상기 판단결과, UB량이 기준UB량 보다 크면 무리한 회전으로 인해 시스템이 파손되는 것을 방지하기 위해 탈수 작업을 정지시키고(S4), UB량이 기준UB량 보다 작으면 세탁기의 회전속도를 더욱 가속시켜 본 탈수를 진행시키게 된다(S5,S6)As a result of the determination, if the UB amount is larger than the reference UB amount, the dehydration operation is stopped to prevent the system from being damaged due to excessive rotation (S4). If the UB amount is smaller than the reference UB amount, the rotation speed of the washing machine is further accelerated. To proceed (S5, S6)
그러나, 상술한 종래 기술은, 세탁기의 탈수 모드시, 고속으로 탈수가 진행되어 세탁물의 종류에 따라 수분이 빠지는 양이 달라지는데, 즉 저함수율과 고함수율의 세탁물이 혼합되어 UB양이 커지게 되고, 이에 따라 탈수속도가 증가할수록 진동과 소음이 증가되는 문제점이 있다. However, in the above-described prior art, in the dehydration mode of the washing machine, the dehydration proceeds at a high speed, and the amount of water deviates depending on the type of laundry, that is, a low water content and a high water content laundry are mixed to increase the amount of UB. Accordingly, there is a problem that vibration and noise increase as the dehydration speed increases.
본 발명은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로, 세탁기를 저속 및 고속으로 운전시켜, 각기 검출한 UB위치와 UB량을 비교하고, 그 비교결과에 근거하여 탈수가 진행되면서 UB양의 변동을 예측하여 포고름을 재실행함으로써, 탈수시 발생하는 과도한 진동을 미연에 방지하도록 한 세탁기의 탈수운전방법을 제공함에 그 목적이 있다. The present invention has been made in order to solve the above problems, by operating the washing machine at a low speed and high speed, comparing the detected UB position and the amount of UB, and the change in the amount of UB while dehydration proceeds based on the comparison result It is an object of the present invention to provide a dehydration operation method of a washing machine to prevent excessive vibration generated during dehydration by re-executing the pore running in anticipation of this.

이하, 본 발명에 의한 세탁기의 탈수 운전방법에 대한 작용 및 효과를 첨부한 도면을 참조하여 상세히 설명한다.Hereinafter, with reference to the accompanying drawings, the operation and effects of the washing machine dehydration operation method according to the present invention will be described in detail.
도3은 본 발명 세탁기의 탈수 운전방법에 대한 실시예의 동작흐름도이다.3 is an operation flowchart of an embodiment of the dehydration operation method of the washing machine of the present invention.
도3에 도시한 바와같이, 본 발명은 세탁기를 일정 저속으로 운전시켜 초기 UB량을 검출하고, 최고속도로 검출되는 위치를 초기 UB위치로 결정하는 단계 (SP1~SP3)와; 일정시간 고속으로 탈수모드로 세탁기를 운전시킨 다음, 일정저속으로 세탁기를 운전시켜 현재 UB량을 검출하고, 최고속도로 검출되는 위치를 현재 UB위치로 결정하는 단계(SP4~SP6)와; 현재 UB량과 초기 UB량의 차이를 검출하여 그 차이값이 소정값 이상인지를 판단하는 단계(SP7)와; 상기 판단결과, 차이값이 소정값 이하이면 세탁기의 탈수 운전을 실행하고, 차이값이 소정값 이상이면 현재 UB위치와 초기 UB위치의 차이값을 위상차로 검출하여 그 위상차가 소정값 이상인지를 판단하는 단계(SP8)와; 상기 판단결과, 위상차가 소정값 이하이면 세탁기의 탈수 운전을 실행하고, 위상차가 소정값 이상이면 포고름을 재실행하는 단계(SP9)로 이루어지며, 이와같은 본 발명의 동작을 설명한다.As shown in Fig. 3, the present invention includes the steps of detecting the initial UB amount by operating the washing machine at a constant low speed, and determining the position detected at the highest speed as the initial UB position (SP1 to SP3); Driving the washing machine in a dehydration mode at a high speed for a predetermined time, and then operating the washing machine at a constant low speed to detect a current UB amount and determining a position detected at the highest speed as the current UB position (SP4 to SP6); Detecting a difference between the current UB amount and the initial UB amount and determining whether the difference is greater than or equal to a predetermined value (SP7); As a result of the determination, if the difference value is less than the predetermined value, the washing machine is dehydrated. If the difference value is more than the predetermined value, the difference value between the current UB position and the initial UB position is detected as a phase difference to determine whether the phase difference is greater than or equal to the predetermined value. Step SP8; As a result of the determination, a dehydration operation of the washing machine is executed when the phase difference is less than or equal to the predetermined value, and SP9 is executed again when the phase difference is greater than or equal to the predetermined value (SP9).
먼저, 세탁기가 세탁모드에서 탈수모드로 전환되면, 도4와 같이 세탁기를 일정 저속으로 운전시켜(SP1), 초기 UB량을 검출하고, 최고속도로 검출되는 위치를 초기 UB위치로 결정한다(SP2,SP3).First, when the washing machine is switched from the washing mode to the dehydration mode, the washing machine is operated at a constant low speed as shown in FIG. 4 (SP1), the initial UB amount is detected, and the position detected at the highest speed is determined as the initial UB position (SP2, SP3).
그 다음, 도4와 같이, 일정시간 고속으로 탈수모드로 세탁기를 운전시키는데 (SP4), 즉 일정시간 동안 세탁물의 수분을 탈수한다.Then, as shown in Figure 4, to operate the washing machine in the dehydration mode at a high speed for a certain time (SP4), that is, to dehydrate the laundry for a certain time.
그 다음, 다시 일정 저속으로 세탁기를 운전시켜 현재 UB량을 검출하고, 최고속도로 검출되는 위치를 현재 UB위치로 결정한다(SP5,SP6).Then, the washing machine is operated at a constant low speed again to detect the current UB amount, and the position detected at the highest speed is determined as the current UB position (SP5, SP6).
그 다음, 상기에서 검출한 현재 UB량과 초기 UB량의 차이값을 검출하여 그 차이값이 소정값(α) 이상인지를 판단하는데(SP7), 이때 상기 소정값(α)는 실험에 의해 기설정된다.Then, the difference value between the detected current UB amount and the initial UB amount is detected, and it is determined whether the difference value is equal to or greater than a predetermined value α (SP7), wherein the predetermined value α is determined by experiment. Is set.
상기 판단결과, 차이값이 소정값(α) 이하이면 세탁기의 탈수 운전을 실행하고(SP10), 차이값이 소정값(α) 이상이면 현재 UB위치와 초기 UB위치의 차이값을 위상차로 검출하여 그 위상차가 소정값(β) 이상인지를 판단하는데(SP8),소정값(β)은 실험에 의해 기설정된다.As a result of the determination, if the difference is less than the predetermined value α, dehydration operation of the washing machine is executed (SP10). If the difference is more than the predetermined value α, the difference value between the current UB position and the initial UB position is detected as a phase difference. It is determined whether the phase difference is greater than or equal to the predetermined value β (SP8), and the predetermined value β is predetermined by experiment.
즉, 상기 위상차는, 도5와 같이, 총회전 각도를 360도의 정수로 나눈 나머지로 결정되는데, 이 위상차를 검출함으로써 UB의 위치변화를 알 수 있다. That is, the phase difference is determined as the remainder obtained by dividing the total rotation angle by an integer of 360 degrees, as shown in FIG. 5. By detecting this phase difference, the position change of the UB can be known.
그 다음, 상기 판단결과, 현재 UB위치와 초기 UB위치의 차이값인 위상차가 소정값(β) 이하이면 세탁기의 탈수 운전을 그대로 실행하고, 현재 UB위치와 초기 UB위치의 차이값인 위상차가 소정값(β)이상이면 포고름을 재실행한후, 상기 과정을 반복수행한다.Next, as a result of the determination, if the phase difference, which is the difference between the current UB position and the initial UB position, is less than or equal to the predetermined value β, the washing machine is dehydrated as it is, and the phase difference, which is the difference between the current UB position and the initial UB position, is predetermined. If the value is greater than or equal to β, the process is repeated after the pore is executed again.
다시 말해서, 본 발명은 세탁기를 저속 및 고속으로 운전시켜, 각기 검출한 UB위치와 UB량을 비교하고, 그 비교결과에 근거하여 탈수시의 UB양 변동을 예측하여 포고름을 재실행함으로써, 탈수시의 과도한 진동이 발생할 확률을 저감시킨다.In other words, the present invention operates the washing machine at a low speed and a high speed, compares the detected UB position with the amount of UB, and predicts the variation in the amount of UB upon dehydration based on the comparison result, and executes the pore again to dehydrate. Reduce the probability of excessive vibrations.

As described in detail above, the present invention operates the washing machine at a low speed and a high speed, compares the detected UB position with the amount of UB, and predicts variation in the amount of UB during dehydration based on the comparison result.
