도 4는 본 발명에 따른 상업용 세탁기의 제어방법을 나타낸 플로우 차트이다.4 is a flowchart illustrating a control method of a commercial washing machine according to the present invention.

본 발명은 상업용 세탁기의 제어방법에 관한 것으로, 특히 본탈수 행정전, 해당 코스에 따라 급수, 세탁 또는 헹굼, 배수, 및 탈수단계를 반복수행하는 세탁/행굼행정에서 세탁시간을 단축하고 불필요하게 낭비되던 세탁시간을 효율적으로 사용하고자 하는 상업용 세탁기의 제어방법에 관한 것이다.The present invention relates to a control method of a commercial washing machine, in particular, prior to the main dehydration administration, according to the course, the washing time and washing time in the washing / rinsing stroke to repeatedly perform the water supply, washing or rinsing, draining, and dehydration step unnecessary waste The present invention relates to a control method of a commercial washing machine to efficiently use the washing time.

일반적으로 드럼세탁기는 세제와 세탁수 및 세탁물이 세탁드럼 내에 투입된 상태에서 구동부의 구동력을 전달받아 회전하는 세탁드럼과 세탁물의 마찰력을 이 용하여 세탁이 이루어지도록 한 장치로서, 세탁물의 손상이 적고, 세탁물이 잘 엉키지 않으며, 두드리고 비벼 빠는 세탁효과를 낼 수 있도록 한 것이다.In general, a drum washing machine is a device that allows washing to be performed by using a friction force of a rotating laundry drum and a laundry by receiving a driving force of a driving unit while detergent, washing water, and laundry are put into a washing drum. It's not tangled, and it's designed to give you a pounding and scrubbing wash effect.

이하, 첨부된 도면을 참조하여 일반적인 드럼세탁기의 구조를 설명하면 다음과 같다.Hereinafter, a structure of a general drum washing machine will be described with reference to the accompanying drawings.

도 1은 일반적인 드럼세탁기의 구조를 개략적으로 나타낸 단면도이고, 도 2는 종래 기술에 따른 세탁기의 세탁 또는 헹굼행정 과정 중 배수단계 완료 후 수행되는 과정을 나타낸 그래프이다.1 is a cross-sectional view schematically showing the structure of a general drum washing machine, Figure 2 is a graph showing a process performed after the completion of the drainage step of the washing or rinsing stroke process of the washing machine according to the prior art.

도 1은 일반적인 드럼세탁기의 구성을 나타낸 단면도로서, 드럼세탁기는 본체(1) 내에 댐퍼(7)와 스프링(6)에 의해 지지된 터브(2)와, 상기 터브 내에 수평축을 중심으로 회전 가능하게 설치된 원통형상의 드럼(3)과, 상기 드럼과 축 결합된 구동모터(5)로 구성된다.1 is a cross-sectional view showing the configuration of a general drum washing machine, the drum washing machine in the main body 1, the tub (2) supported by the damper 7 and the spring (6), and in the tub so as to rotate about a horizontal axis It is composed of a cylindrical drum (3) provided, and a drive motor (5) axially coupled to the drum.

상기 구동모터(5)는 터브(2)의 후면에 로터(5b)와 스테이터(5a)로 구성되어 있는 것으로, 상기 로터(5b)의 구동력을 풀리나 벨트 없이 직접 드럼(3)에 전달하기 위하여 드럼과 함께 회전하는 드럼축(4)이 로터에 직접 연결된다.The drive motor 5 is composed of a rotor 5b and a stator 5a at the rear of the tub 2, and a drum for transferring the driving force of the rotor 5b directly to the drum 3 without a pulley or a belt. The drum shaft 4 which rotates together with the rotor is directly connected to the rotor.

상기 본체(1)의 전면에는 드럼(3)의 개구부와 대응하도록 소정 위치에 도어(8)가 구비되고, 상기 도어와 드럼 사이에는 드럼 내의 밀봉을 유지하는 가스켓(9)이 구비되며, 상기 도어(8)의 상부에는 사용자의 조작 명령을 입력받고 세탁기 전체의 작동을 제어하는 콘트롤러패널(10)이 구비된다.The front surface of the main body 1 is provided with a door 8 at a predetermined position to correspond to the opening of the drum 3, between the door and the drum is provided with a gasket 9 for maintaining a seal in the drum, the door The upper part of the (8) is provided with a controller panel 10 for receiving a user's operation command and controls the operation of the entire washing machine.

이와 같이 구성된 드럼세탁기는 로터(5b)의 회전력이 세탁축(4)을 통해 드럼(3)에 전달되고, 상기 드럼이 회전하면서 리프터(3a)에 의해 세탁물이 들어올려 졌다가 중력에 의해 아래로 떨어지면서 세탁행정을 수행하게 된다.The drum washing machine configured as described above has the rotational force of the rotor 5b transmitted to the drum 3 through the washing shaft 4, and the laundry is lifted by the lifter 3a while the drum rotates, and then down by gravity. As you fall, you will perform a laundry administration.

즉, 상기 드럼(3)의 회전에 의해 상측으로 끌어올려진 세탁물은 소정 높이에 이르렀을 때 자중에 의해 아래로 떨어지며 세탁수와 부딪히게 되고, 이러한 과정을 여러번 반복하면서 세탁물은 세탁수와의 마찰에 의해 세탁된다.That is, the laundry pulled upward by the rotation of the drum (3) falls down by its own weight when it reaches a predetermined height and collides with the wash water, and the laundry is rubbed with the wash water while repeating this process several times. Is washed by.

상기와 같은 동작에 의해 세탁이 수행된 후 탈수동작이 이루어지게 되는데, 상기 배수펌프(도시생략)를 구동시켜 배수라인(도시생략)을 통해 배수를 수행하면서 상기 회전 드럼(3)을 고속으로 회전시켜 원심력에 의한 탈수를 수행한다.After washing is performed by the above operation, a dehydration operation is performed. The rotary drum 3 is rotated at a high speed while driving the drain pump (not shown) to perform drainage through a drain line (not shown). Dehydration by centrifugal force.

도 2는 종래 기술에 따른 세탁기의 세탁 또는 헹굼행정 과정 중 배수단계 완료 후 수행되는 과정을 나타낸 그래프이다. 2 is a graph showing a process performed after the completion of the drainage step of the washing or rinsing stroke process of the washing machine according to the prior art.

도 2를 참조하면, 배수완료 후 포풀림, 1차 내지 3차 밸런싱, 1차 및 2차 간헐탈수, 가속, 정상탈수의 단계를 순차적으로 수행하여 이루어지는데, 상기 포풀림 단계에서는 회전 드럼(3)을 50rpm(미도시)으로 소정시간 회전시켜 세탁물끼리의 엉킴을 해소하고, 상기 1차 내지 3차 밸런싱 단계에서는 108rpm(rpm1)으로 소정시간 회전시켜 세탁물이 회전 드럼(3)의 내부에서 고르게 퍼져서 상기 회전 드럼(3)이 균형을 이루도록 한다.Referring to Figure 2, after the completion of the drainage, the first to third balancing, the first and second intermittent dehydration, acceleration, normal dehydration is performed by sequentially performing the step of rotating the drum (3) ) To rotate the predetermined time to 50rpm (not shown) to eliminate the tangling of the laundry, and in the first to third balancing step by rotating the predetermined time to 108rpm (rpm 1 ) for a predetermined time to wash the laundry evenly inside the rotating drum (3). Spread out to balance the rotating drum 3.

또한, 상기 1차 편심감지단계 결과에 따라 1차 간헐탈수단계를 수행하고, 2차 편심감지단계 결과에 따라 2차 간헐탈수단계를 수행하며, 3차 편심감지단계 결과에 따라 정상 탈수구간으로 진입한다.In addition, the first intermittent dehydration step is performed according to the first eccentric detection step result, the second intermittent dehydration step is performed according to the second eccentric detection step result, and the normal dehydration section is entered according to the third eccentric detection step result. do.

즉, 상기 간헐탈수단계는 탈수동작 초기에 많은 물이 한꺼번에 빠져나오면서 발생되는 소음을 줄이고, 상기 세탁 모터(5)에 가해지는 부하를 줄이기 위한 것으로서 상기 1차 간헐탈수단계는 상기 모터(5)의 회전속도를 170rpm(rpm1a) 까지 가속시켰다가 108rpm(rpm1)으로 감속하는 동작이고, 108rpm(rpm1)으로 감속되면 2차 편심감지단계 후 400rpm(rpm1b)까지 가속시켰다가 다시 108rpm(rpm1)으로 감속하는 동작이다.That is, the intermittent dehydration step is to reduce the noise generated when a large amount of water is drawn out at the beginning of the dehydration operation, and to reduce the load applied to the washing motor 5. and the operation for decelerating the rotational speed to 170rpm (rpm 1a) acceleration was the 108rpm (rpm 1) to, 108rpm (rpm 1) as it decelerates the secondary eccentric sensing step after 400rpm (rpm 1b) were accelerated to the back 108rpm (rpm Deceleration to 1 )

또한, 상기 가속 단계에서는 정상적인 탈수 동작을 수행하기 위해 회전 드럼(3)의 속도를 500rpm((rpm3)까지 상승시키고, 상기 정상탈수 단계에서는 탈수시간이 종료될 때까지 계속적으로 회전 드럼(3)의 속도를 증가시켜 탈수를 수행한다.In addition, in the acceleration step, the speed of the rotating drum 3 is increased to 500 rpm ((rpm 3 ) in order to perform a normal dehydration operation, and in the normal dehydration step, the rotating drum 3 continues until the dehydration time ends. Dehydration is carried out by increasing the speed.

상기의 동작에서 회전 드럼(3)의 속도는 세탁 모터(5)의 구동에 의해 결정되는데, 상기 모터(5)는 세탁모드에서 저속으로 구동되어야 하고, 탈수모드에서 고속으로 구동되어야 한다.In the above operation, the speed of the rotating drum 3 is determined by the driving of the washing motor 5, which must be driven at low speed in the washing mode and at high speed in the dehydration mode.

그러나 이와 같은 일반적인 드럼세탁기는 상기와 같은 편심감지단계에서 편심을 감지하여 탈수로 진입하지 못할 경우 편심해소를 위해 무려 25회나 편심감지를 시도하게 되고, 수차례 반복적으로 간헐탈수를 실시하게 됨으로써 너무나 많은 세탁시간이 낭비되게 된다. 특히 모든 세탁행정이 정해진 시간 내에 이루어져야 하는 상업용 세탁기의 경우, 상기와 같이 행해지는 반복적인 편심감지단계와 간헐탈수단계는 상당한 시간을 소요하게 함으로 세탁시간이 불필요하게 낭비되고, 사용자가 상기와 같은 세탁과정으로 인해 제시간 내에 세탁을 완료할 수 없게 되면 사용자는 상업용 세탁기에 세탁비용을 재투입하여 다시 한번 세탁을 시도해야함으로 사 용자의 불만을 초래하며 비경제적이게 되는 문제점이 있다.However, such a general drum washing machine detects the eccentricity in the eccentric sensing stage as described above and attempts to detect the eccentric as many as 25 times to resolve the eccentricity and repeatedly performs intermittent dehydration several times. Washing time is wasted. In particular, in the case of a commercial washing machine in which all washing administrations must be made within a predetermined time, the repetitive eccentricity detection step and the intermittent dehydration step performed as described above take considerable time, so that washing time is unnecessarily wasted, When the laundry cannot be completed in time due to the process, the user has to re-inject the washing fee into a commercial washing machine and attempt to wash again, which causes a user's dissatisfaction and becomes uneconomical.

또한 빠른 세탁사이클이 요구되는 상업용 세탁기 사업장에서 상기와 같은 세탁행정은 세탁사이클 1회 회전 시의 소요시간이 너무 길게 됨으로 빠른 세탁사이클로 이윤을 추구하는 상업용 세탁기 사업장의는 사업주에게 경제적인 부분에 손해를 끼칠 수 있다. In addition, in the washing machine business where a fast washing cycle is required, the washing administration as described above takes too much time for one revolution of the washing cycle. It can be.

상기 문제점을 해결하고자 안출된 본 발명의 상업용 세탁기의 제어방법은 편심해소를 위해 수차례 반복되던 편심감지와 간헐탈수를 생략하여 불필요하게 낭비되던 세탁시간을 효율적으로 사용되게 하고 사용자 및 사업주의 경제성을 향상시키는데 그 목적이 있다.The control method of the commercial washing machine of the present invention devised to solve the above problems eliminates eccentricity detection and intermittent dehydration, which have been repeated several times to solve the eccentricity, thereby efficiently using unnecessary washing time and economical efficiency of users and business owners. The purpose is to improve.

상기한 목적을 달성하기 위해 본 발명은 본탈수 행정 전, 해당 코스에 따라 급수, 세탁 또는 헹굼, 배수, 및 탈수단계를 반복수행하는 세탁 또는 헹굼행정에 있어서, 상기 배수단계 완료 후 포량을 감지하는 포량감지단계; 상기 포량감지단계 후 편심감지RPM으로 드럼을 회전시켜 편심을 감지하고 편심해소 여부를 판단하는 편심감지단계; 그리고 상기 편심감지단계 후 상기 편심해소 여부에 따라 RPM을 달리하여 탈수를 수행하는 탈수단계;를 포함하는 상업용 세탁기의 제어방법을 제공한다.In order to achieve the above object, the present invention, in the washing or rinsing administration to repeatedly perform the water supply, washing or rinsing, draining, and dehydration step according to the course before the main dehydration stroke, detecting the amount of water after completion of the draining step Capacity detection step; An eccentric detection step of detecting an eccentricity and determining whether to cancel the eccentricity by rotating the drum with the eccentricity detection RPM after the quantity detection step; And a dehydration step of performing dehydration by varying RPM depending on whether the eccentricity is resolved after the eccentricity detection step.

이하 첨부도면을 참고하여 본 발명의 상업용 세탁기의 제어방법의 바람직한 실시예를 설명하면 다음과 같다.Hereinafter, a preferred embodiment of the control method of a commercial washing machine of the present invention with reference to the accompanying drawings.

도 3은 본 발명에 따른 상업용 세탁기의 세탁 또는 헹굼행정 과정 중 배수단계 완료 후 수행되는 과정을 나타낸 그래프이고, 도 4는 본 발명에 따른 상업용 세탁기의 제어방법을 나타낸 플로우 차트이다.3 is a graph showing a process performed after the completion of the drainage step of the washing or rinsing administration process of a commercial washing machine according to the present invention, Figure 4 is a flow chart showing a control method of a commercial washing machine according to the present invention.

본 발명은 상업용 세탁기의 제어방법에 관한 것으로, 구체적으로 설명하면 상업용 세탁기에서 본탈수 행정 전, 해당 코스에 따라 급수, 세탁 또는 헹굼, 배수, 탈수단계를 반복수행하는 세탁/헹굼행정의 제어방법에 관한 것이고, 더욱 구체적으로 설명하면 배수단계 완료 후 편심감지 시간을 단축하고, 간헐탈수를 생략하여 전체적인 세탁시간을 단축시키는 상업용 세탁기의 제어방법에 관한 것이다. The present invention relates to a control method of a commercial washing machine. Specifically, the present invention relates to a control method of a washing / rinsing administration which repeatedly performs water supply, washing or rinsing, draining, and dehydrating steps according to a corresponding course before a main dehydration stroke in a commercial washing machine. In more detail, the present invention relates to a control method of a commercial washing machine, which shortens the eccentricity detection time after the completion of the drainage step and reduces the overall washing time by omitting intermittent dehydration.

우선, 사용자가 동작시작 명령을 입력하면 도 4에 도시된 바와 같이 해당 세탁코스에 따라 급수, 세탁 또는 헹굼, 배수단계를 수행한다.(S1~S3)First, when a user inputs an operation start command, water supply, washing or rinsing and draining are performed according to the corresponding washing course as shown in FIG. 4 (S1 to S3).

상기 배수단계(S3) 완료 후 해당 세탁물의 포량을 감지하는 포량감지단계를 수행한다.(S4)After completion of the draining step (S3) performs a quantity detection step of detecting the quantity of the laundry. (S4)

이후 포량감지단계(S4)가 완료되면 편심감지RPM(rpm1)으로 드럼을 회전시켜 편심을 감지하고 편심해소 여부를 판단하는 편심감지단계를 수행한다.(S5)After the quantity detection step (S4) is completed, the eccentric detection RPM (rpm 1 ) to rotate the drum to detect the eccentricity and to determine whether the eccentricity is resolved.

이때 편심해소 여부는 감지된 편심량이 기 설정된 기준편심량 초과인지 이하인지 여부에 따라 판단된다. 즉 상기 감지된 편심량이 기준편심량 이하이면 편심은 해소된 것이고, 상기 감지된 편심량이 기준편심량을 초과하면 편심은 해소되지 않은 것을 뜻한다.At this time, whether the eccentricity is resolved is determined based on whether the detected eccentricity is greater than or equal to the preset reference eccentricity. That is, when the detected eccentricity is less than the reference eccentricity, the eccentricity is solved. When the detected eccentricity exceeds the reference eccentricity, it means that the eccentricity is not resolved.

또한 이때 상기 편심감지RPM(rpm1)은 일반적으로 종래 기술의 편심감지단계 에서 제시되던 108rpm인 것이 바람직하다. 그러나 상기 편심감지RPM(rpm1)이 반드시 이에 한정된 것은 아니다.In addition, the eccentricity detection RPM (rpm 1 ) is generally preferably 108rpm that was presented in the prior art eccentricity detection step. However, the eccentric detection RPM (rpm 1 ) is not necessarily limited thereto.

또 이때 상기 편심감지단계(S5)는 감지된 편심량이 기준편심량 이하 일 때까지 소정횟수(n) 편심감지를 실시한다. 이때 상기 소정횟수(n)는 5회 이하로 제한되는 것이 바람직하다. 따라서 상기와 같이 소정횟수(n)로 편심감지가 제한되고 종래의 편심감지단계 중간 중간에서 행해지던 여러 번의 간헐탈수단계가 생략됨으로써 불필요하게 낭비되던 세탁시간은 단축되고 세탁시간이 효율적으로 활용되게 된다.In this case, the eccentricity detecting step S5 performs eccentricity detection a predetermined number of times until the detected eccentricity is less than or equal to the reference eccentricity. At this time, the predetermined number n is preferably limited to five or less times. Therefore, the eccentricity detection is limited to a predetermined number n as described above, and the intermittent dehydration step that is performed in the middle of the conventional eccentricity detection step is omitted, thereby reducing unnecessary washing time and efficiently utilizing the washing time. .

즉 도 2에 도시된 바와 같이 종래에는 편심감지하여 탈수로 진입하지 못할 경우 25회나 편심감지를 시도하고, 편심감지단계 중간 중간에 여러 번의 간헐탈수를 반복적으로 시행한 뒤 다음 행정으로 진입하게 된다. 이 경우 상당한 세탁시간이 소요되게 됨으로 모든 세탁행정이 정해진 시간 내에 끝나야 하는 상업용 세탁기에서 나머지 세탁행정을 수행하기에는 시간이 부족할 수도 있다. 따라서 상기와 같은 이유로 세탁시간이 부족하게 될 경우, 사용자는 상업용 세탁기에 세탁비용을 재 지불 하여야함으로 사용자의 불만은 초래되고 또한 사용자는 과도한 세탁비용을 지불하여야 함으로 비경제적이게 된다. 또한 빠른 세탁사이클이 요구되는 상업용 세탁기 사업장에서 상기와 같은 세탁행정은 1회 세탁사이클의 소요시간이 너무 길게됨으로 사업주의 이윤추구를 방해하는 요소가 되어 사업주에게 경제적인 손해를 끼칠 수 있다. That is, as shown in FIG. 2, when the eccentricity detection does not enter the dehydration, the eccentricity detection is attempted 25 times, and the intermittent dehydration is repeatedly performed in the middle of the eccentricity detection step before entering the next stroke. In this case, since a considerable washing time is required, it may not be enough time to perform the rest of the laundry administration in a commercial washing machine in which all washing administrations must be completed within a predetermined time. Therefore, when the washing time is insufficient for the above reason, the user has to pay the washing fee to the commercial washing machine, so that the user's dissatisfaction is caused and the user has to pay excessive washing cost, which is uneconomical. In addition, such a washing administration in a commercial washing machine that requires a fast washing cycle is a factor that hinders the employer's profit pursuit because the time required for one washing cycle is too long, which may cause economic damages to the employer.

이에 반해 본 발명은 전술된 바와 같이 상기 편심감지단계(S5)에서 소정횟 수(n)로 편심감지가 제한되고, 간헐탈수단계가 생략됨으로써 세탁시간이 단축되고 불필요하게 낭비되던 세탁시간을 효율적으로 사용하게 되며, 추가되는 세탁시간 없이 제 세탁시간 내에 세탁을 완료할 수 있어 부가적인 비용발생이 방지되어 사용자에게 경제적이고, 빠른 세탁사이클을 가능하게 하여 사업주의 이윤추구도 향상시킬 수 있다.On the contrary, in the present invention, as described above, the eccentricity detection is limited to a predetermined number n in the eccentricity detection step S5, and the intermittent dehydration step is omitted, thereby shortening the washing time and efficiently wasting unnecessary waste. In addition, since the washing can be completed within the washing time without additional washing time, additional costs can be prevented, thereby enabling the user to have an economical and fast washing cycle, thereby improving the employer's profit pursuit.

이후 상기 편심감지단계(S5) 완료 후, 상기 편심감지단계(S5)에서 판단된 편심해소여부에 따라 RPM을 달리하여 탈수단계를 수행하게 된다. 이때 상기 탈수단계는 도 4에 도시된 바와 같이 정식탈수단계(S6)와 약식탈수단계(S7)로 나눌 수 있다.After the completion of the eccentric detection step (S5), the dehydration step is performed by varying the RPM depending on whether the eccentric resolution determined in the eccentric detection step (S5). At this time, the dehydration step may be divided into a formal dehydration step (S6) and a brief dehydration step (S7) as shown in FIG.

즉 상기 편심감지단계(S5)에서 감지된 편심량이 기준편심량 이하가 될 때까지 제한된 소정횟수(n)내로 편심감지를 시도하여도 편심이 해소되지 않으면, 소정시간(t) 동안 약식탈수RPM(rpm2)으로 약식탈수단계(S7)를 수행하게 된다. 이때 상기 소정시간(t)은 20초인 것이 바람직하다. 그러나 반드시 이에 한정된 것은 아니다.That is, if the eccentricity is not resolved even if the eccentricity detection is attempted within a limited number of times n until the eccentricity detected in the eccentricity detection step S5 is less than or equal to the reference eccentricity, the abbreviated dehydration RPM (rpm) for a predetermined time t 2 ) to perform a brief dehydration step (S7). At this time, the predetermined time (t) is preferably 20 seconds. However, it is not necessarily limited thereto.

또한 이때 상기 약식탈수RPM(rpm2)은 도 3의 (a)에 도시된 바와 같이 상기 편심감지단계(S5)의 상기 편심감지RPM(rpm1)과 동일하거나 도 3의 (b)에 도시된 바와 같이 상기 편심감지RPM(rpm1)보다 높고 후술되는 정식탈수단계(S6)의 정식탈수RPM(rpm3)보다 낮은 것이 바람직하다.(S7)In addition, the abbreviated dehydration RPM (rpm 2 ) is the same as the eccentric sensing RPM (rpm 1 ) of the eccentric sensing step (S5) as shown in (a) of FIG. 3 or shown in (b) of FIG. As described above, it is preferable that the eccentricity detection RPM (rpm 1 ) is higher and lower than the formal dehydration RPM (rpm 3 ) of the formal dehydration step (S6) described later.

도 3(a)에 도시된 바와 같이 상기 약식탈수RPM(rpm2)과 상기 편심감지 RPM(rpm1)이 동일한 경우, 상기 편심감지단계(S5) 완료 후 RPM을 가속시키는 별도의 과정없이 상기 편심감지RPM(rpm1)과 동일한 RPM을 소정시간(t) 동안 더 유지하여 드럼을 회전시켜 상기 약식탈수단계(S7)를 수행함으로써 세탁시간 단축은 물론 소정의 탈수효과도 볼 수 있다. As shown in FIG. 3 (a), when the abbreviated dehydration RPM (rpm 2 ) and the eccentric sensing RPM (rpm 1 ) are the same, the eccentricity without the additional process of accelerating the RPM after the eccentric sensing step S5 is completed By maintaining the same RPM as the sensing RPM (rpm 1 ) for a predetermined time (t), the drum is rotated to perform the abbreviated dehydration step (S7), thereby reducing washing time as well as a predetermined dehydration effect.

또 도 3(b)에 도시된 바와 같이 상기 약식탈수RPM(rpm2)이 상기 편심감지RPM(rpm1)보다 높고 후술되는 정식탈수단계(S6)의 정식탈수RPM(rpm3)보다 낮은 경우, 필요이상의 RPM을 편심이 해소되지 않은 상태에서 과도하게 가속시키지 않고 소정시간(t) 동안 적정RPM을 유지하며 드럼을 회전시켜 상기 약식탈수단계(S7)를 수행함으로써 세탁시간 단축은 물론 소정의 탈수효과도 볼 수 있다.In addition, as shown in Figure 3 (b) when the abbreviated dehydration RPM (rpm 2 ) is higher than the eccentric sensing RPM (rpm 1 ) and lower than the formal dehydration RPM (rpm 3 ) of the formal dehydration step (S6), By maintaining the proper RPM for a predetermined time (t) without excessive acceleration in the state that the eccentricity is not resolved, the drum is rotated to perform the abbreviated dehydration step (S7) to shorten the washing time as well as a predetermined dehydration effect. Can also be seen.

한편 본 발명에서 상기 편심감지단계(S5)에서 감지된 편심량이 기준편심량 이하가 될 때까지 제한된 소정횟수(n)내로 편심감지를 시도하여 편심이 해소되면, 도 3(c)에 도시된 바와 같이 상기 편심감지단계(S5) 완료 후 정식탈수RPM(rpm3)으로 정식탈수단계(S6)를 수행한다. 이때 상기 정식탈수단계(S6)의 정식탈수RPM(rpm3)은 상기 편심감지단계(S5)의 편심RPM(rpm1)보다 높은 RPM으로 드럼을 회전시켜 탈수를 수행한다.(S6)On the other hand, in the present invention, if the eccentricity is resolved by attempting the eccentricity detection within a limited number of times (n) until the amount of eccentricity sensed in the eccentricity sensing step (S5) is less than the reference eccentricity, as shown in Fig. 3 (c). After completion of the eccentric detection step (S5) performs a formal dehydration step (S6) with a formal dehydration RPM (rpm 3 ). At this time, the formal dehydration RPM (rpm 3 ) of the formal dehydration step (S6) is carried out by rotating the drum at a higher RPM than the eccentric RPM (rpm 1 ) of the eccentric detection step (S5) (S6).

따라서 상기와 같은 정식탈수단계(S6)는 수차례 반복적으로 행해지던 편심감지단계와 간헐탈수단계를 생략하고, 제한된 소정횟수(n) 내에서만 편심감지를 시도하여 탈수를 수행함으로써 세탁시간 단축은 물론 편심이 해소된 상태에서 상기 약 식탈수단계(S7)보다 높은 RPM으로 탈수를 수행함으로써 더 큰 탈수효과를 기대할 수 있게 된다.Therefore, the formal dehydration step S6 omits the eccentricity detection step and the intermittent dehydration step that have been repeatedly performed several times, and reduces the washing time by performing the eccentricity detection only within a limited number of times n to perform dehydration. It is possible to expect a greater dehydration effect by performing dehydration at a higher RPM than the weak plant dehydration step (S7) in the eccentricity is resolved.

이후 상기와 같은 탈수단계(S6, S7)를 완료 한후, 급수단계로 진입하여 나머지 세탁행정을 수행함으로써 세탁을 완료한다.(S8)After completing the dehydration step (S6, S7) as described above, and enters the water supply step to complete the washing by performing the remaining washing administration. (S8)

이상에서 살펴본 바와 같이 본 발명의 상업용 세탁기의 제어방법은 상기 편심감지단계에서 제한된 소정횟수(n)만큼만 편심감지를 시도한 뒤 편심해소여부에 따라 적정한 RPM으로 소정시간(t)을 유지하며 드럼을 회전시킴으로써 소정의 탈수효과도 기대할 수 있으며, 수차례 반복적으로 행해지던 편심감지단계와 간헐탈수단계를 생략하여 세탁시간을 단축하고, 상업용 세탁기의 목적에 맞게 빠른 세탁 사이클을 갖게 하여 불필요하게 낭비되던 세탁시간을 효율적으로 사용되게 하여 경제성을 향상시키는 상업용 세탁기의 제어방법을 제공하는데 효과가 있다.As described above, the control method of the commercial washing machine of the present invention attempts to detect the eccentricity only by a limited number of times n in the eccentric detection step, and maintains a predetermined time t at an appropriate RPM depending on whether the eccentricity is resolved. The dehydration effect can also be expected. By eliminating the eccentricity detection step and the intermittent dehydration step, which have been repeatedly performed several times, the washing time can be shortened. It is effective to provide a control method of a commercial washing machine to improve the economics by making it efficiently used.
