Description
본 발명은 원심투과세탁기에 관한 것으로 특히, 세탁공정이 완료된후 헹굼공정을 실행시키기 위하여 작동되는 배수모우터와 함께 구동모우터를 구동시켜 상기 구동모우터의 회전에 의해 간헐탈수 및 본탈수를 수행하거나 배수모우터의 작동과 동시에 구동모우터를 구동시켜 곧바로 본탈수를 수행케 함으로서 헹굼공정중에 소요되는 배수 대기시간을 삭제하여 보다 신속한 헹굼공정이 이루어지도록 하는 동시에 세탁공정을 거치면서 뭉쳐있는 세탁물을 고르게 펴줌으로서 세탁내조에 언바란스가 발생되는 것을 방지할수 있는 원심투과세탁기의 배수 제어방법에 관한 것이다.The present invention relates to a centrifugal permeable washing machine, and in particular, to drive the driving motor together with the drainage motor operated to perform the rinsing process after the washing process is completed to perform intermittent dehydration and main dewatering by the rotation of the drive motor. In addition, by driving the driving motor at the same time as the drain motor is operated, the main dewatering is performed immediately, eliminating the waiting time for drainage during the rinsing process so that a faster rinsing process is performed, and the laundry that is stuck together during the washing process is removed. The present invention relates to a method for controlling drainage of a centrifugal washing machine which can prevent unbalance from occurring in a washing tank by spreading evenly.
종래 세탁기의 탈수공정을 도3의 플루우챠트에 의해 상세히 설명하기로 한다. The dehydration process of the conventional washing machine will be described in detail by the flow chart of FIG.
먼저, 세탁공정이 완료되고 헹굼공정이 시작되면 도 1의 배수모우터(5)가 작동(S1)되면서 배수로를 개방하여 배수를 하게 된다. First, when the washing process is completed and the rinsing process is started, the drainage motor 5 of FIG. 1 is operated (S1) while opening the drainage channel to drain.
그리고, 상기 배수모우터의 작동(S1)에 이어 수위감지센서에 의한 공수위(S2)여부를 감지하게 된다. Then, after the operation (S1) of the drainage motor to detect whether the air level (S2) by the water level sensor.
그러나, 도2에 나타낸 바와같이 배수되는 세탁수가 에어챔버(3)에서 모두 빠져나와 세탁외조(2)의 바닥면에 잔류되어 있는 상태(h)에서는 에어챔버(3)와 연결된 수위감지 센서는 이를 감지 하지 못하게 된다. However, as shown in FIG. 2, when the washing water drained out of the air chamber 3 and remains on the bottom surface of the washing tub 2, the water level sensor connected to the air chamber 3 is connected thereto. It will not be detected.
따라서, 상기 세탁외조(2)의 바닥면에 차여 있는 잔수가 배수될때까지 기다리기 위한 배수대기시간(t)을 필히 주어야 한다. Therefore, it is necessary to give a drainage waiting time t to wait for the residual water filled on the bottom surface of the washing tub 2 to be drained.
즉, 상기 배수대기시간(t)이 경과(S3)됨으로서 비로소 세탁외조(2) 바닥면의 잔수를 배수할수 있게 된다. That is, the drain waiting time (t) is elapsed (S3) until it is possible to drain the remaining water on the bottom surface of the laundry outer tub (2).
그리고, 상기와 같이 배수대기시간 경과(S3)후에는 세탁내조에 공수위가 된 상태이므로 간헐탈수(S4)를 시작하게 된다. As described above, after the draining waiting time elapses (S3), the water level is set in the washing tank, so that the intermittent dehydration (S4) is started.
상기의 간헐탈수(S4)는 구동모우터(5)가 온,오프를 여러번 반복하면서 점차적으로 온상태를 길게 연장시킴으로서 설정된 일정시간 동안 간헐탈수를 하게 된다. The intermittent dehydration (S4) is intermittent dehydration for a predetermined time by the drive motor (5) is repeatedly extended on, off several times, gradually extending the on state.
또한, 상기의 간헐탈수(S4)가 이루어진 후에는 헹굼 본탈수(S5)가 이어지는바, 상기 구동모우터(5)의 고속회전에 의해 세탁내조(4)가 고속으로 회전되면서 세탁물에 흡수되어 있는 세탁수를 강제로 탈수 시키게 된다. In addition, after the intermittent dehydration (S4) is made, the rinse main dehydration (S5) is continued, the washing tank 4 is rotated at a high speed by the high speed rotation of the drive motor 5 is absorbed in the laundry. Forced dewatering of the wash water.
상기와 같은 헴굼본탈수(S5)를 일정시간동안 실행한 다음에는 급수과정으로 이어지면서 상기와 동일한 과정을 여러번 반복하게 된다. After performing the hemgum dehydration (S5) as described above for a predetermined time, the same process as described above is repeated several times while continuing to the water supply process.
그러나, 상기와 같은 종래 헹굼공정에서는 세탁수가 배수되는 시간 즉, 배수대기 시간(S3)이 필요했기 때문에 헹굼공정을 실행하는데 있어서 많은 시간을 낭비하게 되는 문제점을 가지고 있었다. However, the conventional rinsing process as described above had a problem in that a lot of time wasted in executing the rinsing process because the washing water was drained, that is, the drain waiting time (S3).
특히, 상기 세탁내조(4)의 세탁물들은 세탁내조(4)의 정,역회전에 의해 세탁을 하기 때문에 세탁공정이 완료되면 세탁물이 세탁내조의 벽면에 밀착된 상태로 뭉쳐있게 된다. In particular, since the laundry of the washing tub 4 is washed by the forward and reverse rotation of the washing tub 4, when the washing process is completed, the laundry is stuck to the wall of the washing tub.
상기와 같이 세탁내조에 세탁물이 뭉쳐있는 상태에서 그대로 세탁수의 수위가 내려가는 상황이므로 세탁내조의 내부에는 세탁물들이 풀어지지 않고 뭉쳐있는 상태를 유지하게 된다. Since the water level of the washing water is intact in the state in which the laundry is stuck in the washing tub as described above, the laundry is not released inside the washing tub and remains united.
따라서, 간헐탈수를 하기 위해 구동모우터(5)를 회전시키면 상기의 뭉쳐진 세탁물들에 의해 세탁내조(4)에 언바란스가 발생하게 되고 상기 세탁내조(4)의 언바란스에 의해 진동 및 소음등이 발생하게 된다. Accordingly, when the driving motor 5 is rotated to intermittently dehydrate, unbalance is generated in the washing tub 4 by the agglomerated laundry, and vibration and noise are generated by unbalancing of the washing tub 4. Done.
상기와 같은 세탁물의 언바란스에 의해 발생되는 소음 및 진동에 의해 세탁성능이 저하되는 등의 문제점을 가지고 있었다.There was a problem that the washing performance is reduced by the noise and vibration generated by the unbalance of the laundry as described above.
이러한 종래의 문제점 등을 해결 보완하기 위한 본발명의 목적은, 원심투과세탁기의 헹굼공정을 실행시 보다 신속한 헹굼공정을 실행할수 있도록하여 세탁기 전체의 운전시간을 감촉시킬수 있도록 하고, 세탁공정을 거치면서 세탁내조에 뭉쳐있는 세탁물들을 고르게 풀어줌으로서 탈수시 세탁내조가 언바란스에 의해 진동 및 소음 등을 발생시키는 것을 방지할 수 있도록 하는 목적을 제공한다. The purpose of the present invention to solve and solve the conventional problems, such as to allow the rinsing process of the centrifugal washing machine to perform a faster rinsing process to feel the operating time of the washing machine as a whole, while going through the washing process It provides an object to prevent the laundry inner tank from generating vibration and noise by unbalance when dehydration by evenly unloading the laundry stuck in the washing tank.
상기의 목적을 달성하기 위하여 본 발명은, 세탁공정이 이루어지는 세탁단계; 상기 세탁단계 후 배수모우터와 구동모우터가 동시에 작동되어, 세탁수를 공수위까지 배수시키지 않고 일부만 배수시켜 세탁물들이 세탁수와 부딪히면서 엉킴이 풀어지는 배수 및 간헐탈수단계; 상기 배수 및 간헐탈수단계가 이루어진 후 본 탈수가 이루어지는 본 탈수단계; 상기 본 탈수단계 후 급수와 헹굼이 순차적으로 이루어지는 급수 및 헹굼단계;를 포함하여 이루어지는 것을 특징으로 한다. In order to achieve the above object, the present invention, the washing step is made; After the washing step, the drainage motor and the driving motor are operated at the same time, draining and intermittent dewatering step of tangling the laundry while colliding with the wash water by draining only part of the washing water without draining to the airborne level; A main dehydration step of performing dehydration after the drainage and intermittent dehydration steps are made; It characterized in that it comprises a; water and rinsing step in which the water supply and rinsing is performed sequentially after the present dehydration step.
이하, 본 발명 제1실시예의 배수 제어방법을 도4에 의해 상세히 설명한다. Hereinafter, the drainage control method of the first embodiment of the present invention will be described in detail with reference to FIG.
원심투과세탁기의 헹굼공정중에 소요되는 배수 대기시간을 삭제하여 보다 신속한 헹굼공정이 이루어지도록 하는 동시에 세탁공정에 의해 뭉쳐있는 세탁물을 고르게 펴줌으로서 세탁내조에 언바란스가 발생되는 것을 방지하기 위하여 배수모우터의 작동과 동시에 구동모우터를 회전시켜서 간헐탈수와 본 탈수를 실행시킬 수 있도록 된 것이다. In order to prevent the occurrence of unbalance in the washing tank by eliminating the waiting time for the drainage during the rinsing process of the centrifugal permeation machine, the rinsing process can be performed faster and the unevenness of the washing tank is spread evenly. Simultaneous dehydration and main dehydration can be performed by rotating the drive motor at the same time as the operation.
그리고, 본발명의 제 2실시예는 도5와 같이 제1실시예의 배수 모우터의 작동과 동시에 세탁수를 공수위까지 배수시키지 않고 일부만 배수시킨 후 간헐탈수를 실행시킬 수 있도록 된 것이다. In the second embodiment of the present invention, as shown in FIG. 5, at the same time as the operation of the drainage motor of the first embodiment, only part of the washing water is drained without draining the water to the air supply level, and intermittent dehydration can be performed.
또한, 본 발명 제3실시예의 배수 제어방법을 도6에 의해 상세히 설명한다. Further, the drainage control method of the third embodiment of the present invention will be described in detail with reference to FIG.
원심투과세탁기의 헹굼공정중에 소요되는 배수 대기시간을 삭제하여 보다 신속한 헹굼공정이 이루어지도록 하는 동시에 세탁공정에 의해 뭉쳐있는 세탁물을 고르게 펴줌으로서 세탁내조에 언바란스가 발생되는 것을 방지하기 위하여 배수모우터의 작동과 동시에 구동모우터를 회전시켜서 본탈수를 실행시킬수 있도록 된 것이다. In order to prevent the occurrence of unbalance in the washing tank by eliminating the waiting time for the drainage during the rinsing process of the centrifugal permeation machine, the rinsing process can be performed faster and the unevenness of the washing tank is spread evenly. Simultaneously with the operation, the drive motor can be rotated to perform the main dehydration.
이와 같이 된 본 발명의 작용을 설명하면 다음과 같다. Referring to the operation of the present invention as described above is as follows.
먼저, 도 4의 제 1 실시예에서 세탁 공정 완료 후 헹굼 공정이 시작되면 배수 모우터의 온과 동시에 간헐탈수(S101)과정이 병행되어진다. First, when the rinsing process is started after the washing process is completed in the first embodiment of FIG. 4, the intermittent dehydration (S101) is performed simultaneously with the on-off of the drain motor.
즉, 상기 배수 모우터가 작동되면서 배수로를 개방하는 동시에 구동모우터가 회전되면서 간헐탈수를 하게 된다. That is, the drainage motor is operated to open the drainage path and at the same time the driving motor rotates to intermittently dehydrate.
그리고, 상기 간헐탈수가 설정시간(S102)동안 지속된 후에는 본 탈수(S103)가 설정 시간동안 이루어진 뒤 급수과정(S104)으로 이어지게 된다.Then, after the intermittent dehydration is continued for the set time (S102), the main dehydration (S103) is made for a set time and then continues to the water supply process (S104).
상기와 같이 본 발명의 제 1실시예에서는 배수를 기다리는 종래의 배수대기시간이 없기 때문에 헹굼시간이 매우 빨라지게 되며 아울러 세탁기의 전체 운전시간도 매우 신속하게 된다. As described above, in the first embodiment of the present invention, since there is no conventional drainage waiting time for waiting for drainage, the rinsing time becomes very fast and the overall operating time of the washing machine is also very fast.
그리고, 상기 세탁내조가 간헐탈수를 하기 위해 회전을 하기 때문에 세탁공정을 거치면서 세탁내조의 벽면에 밀착되어 뭉쳐있는 세탁물들이 배수되는 세탁수와 부딪치면서 풀어지는 상태가 된다. Since the washing tub is rotated for intermittent dehydration, the laundry tub is in a state of being loosened while colliding with the washing water being drained to the wall of the tub while washing.
따라서, 상기 세탁물의 풀어지는 현상에 의해 세탁내조의 언바란스를 방지할 수 있게 되므로 세탁내조의 진동 및 소음 등을 막을 수 있게 되고 향상된 헹굼성능을 얻을 수 있게 된다. Therefore, the unbalancing of the washing tank can be prevented by the phenomenon of loosening of the laundry, thereby preventing vibration and noise of the washing tank and obtaining improved rinsing performance.
그리고, 도5의 제 2실시예에서는 제1실시예의 배수모우터의 작동(S111)과 동시에 세탁수를 공수위까지 배수시키지 않고 일부만 배수시키기 위한 일정시간 경과과정(S112)을 갖게 된다. In addition, in the second embodiment of FIG. 5, at the same time as the operation of the drain motor of the first embodiment (S111), a predetermined time lapse process (S112) is performed to drain only a part of the washing water without draining it to the airborne level.
즉, 상기의 세탁수를 조금만 배수시킨 뒤 간헐탈수(S113)과정을 실행함으로서 세탁내조의 벽면에 밀착되어 뭉쳐있는 세탁물들이 배수되는 세탁수와 부딪치면서 풀어지는 상태가 된다. That is, by draining the wash water only a little after the intermittent dehydration (S113) process is in a state that is loosened while hitting the wash water is in close contact with the washing water is drained close to the wall of the washing tank.
따라서, 상기 세탁물의 풀어지는 현상에 의해 세탁내조의 언바란스를 방지할 수 있게 되므로 세탁내조의 진동 및 소음 등을 막을 수 있게 되고 향상된 헹굼성능을 얻을 수 있게 된다. Therefore, the unbalancing of the washing tank can be prevented by the phenomenon of loosening of the laundry, thereby preventing vibration and noise of the washing tank and obtaining improved rinsing performance.
또한, 상기 간헐탈수(S113)과정을 설정시간(S114)동안 수행한 뒤에는 본탈수(S115)와 급수(S116)그리고 헴굼(S117)과정이 연속적으로 이어지게 된다. In addition, after the intermittent dehydration (S113) process is performed for a set time (S114), the main dehydration (S115), water supply (S116) and the hem (S117) process is continued.
한편, 도 6의 제 3실시예에서는 헹굼공정이 시작되면 배수모우터의 온과 동시에 본탈수(S121)과정이 병행되어진다. Meanwhile, in the third embodiment of FIG. 6, when the rinsing process is started, the main dewatering (S121) process is performed simultaneously with the on-off of the drain motor.
즉, 상기 배수모우터가 작동되면서 배수로를 개방하는 동시에 구동모우터가 회전되면서 본 탈수(S111)를 하게 된다. That is, the drainage motor is operated while opening the drainage path and at the same time the driving motor is rotated to perform this dehydration (S111).
그리고, 상기 본 탈수(S111)가 설정 시간동안 지속된 후에는 급수과정(S122) 및 헹굼과정(S123)으로 이어지게 된다. Then, after the main dehydration (S111) is continued for a set time, the water supply process (S122) and rinsing process (S123) is continued.
상기와 같이 본 발명의 제 3실시예에서도 배수를 기다리는 종래의 배수대기시간이 없기 때문에 헹굼시간이 매우 빨라지게 되며 아울러 세탁기의 전체 운전시간도 매우 신속하게 된다. In the third embodiment of the present invention as described above, since there is no conventional drainage waiting time for waiting for drainage, the rinsing time becomes very fast and the overall operating time of the washing machine is also very fast.
그리고, 상기 세탁내조가 본 탈수를 하기 위해 회전을 하기 때문에 세탁공정을 거치면서 세탁내조의 벽면에 밀착되어 뭉쳐있는 세탁물들이 배수되는 세탁수와 부딪치면서 풀어지는 상태가 된다. In addition, since the washing tub is rotated to dehydrate the laundry, the laundry tub is brought into close contact with the wall of the washing tub while being washed with the drained wash water.
따라서, 상기 세탁물의 풀어지는 현상에 의해 세탁내조의 언바란스를 방지할 수 있게 되므로 세탁내조의 진동 및 소음 등을 막을 수 있게 되고 향상된 헹굼성능을 얻을 수 있게 된다.Therefore, the unbalancing of the washing tank can be prevented by the phenomenon of loosening of the laundry, thereby preventing vibration and noise of the washing tank and obtaining improved rinsing performance.
이와 같이 구성된 본 발명은, 원심투과세탁기의 헹굼공정시 배수모우터의 작동과 동시에 구동모우터를 구동시켜 간헐탈수 및 본탈수를 실행시키거나, 상기 헹굼공정시 배수모우터의 작동과 동시에 구동모우터를 구동시켜 직접 본탈수를 실행시킴으로서, 보다 신속한 헹굼공정을 실행할수 있도록 하여 세탁기 전체의 운전시간을 감촉시킬수 있고 상기 세탁공정을 거치면서 세탁내조에 뭉쳐있는 세탁물들을 고르게 풀어 주어 탈수시 세탁내조가 언바란스에 의해 진동 및 소음등을 발생시키는 것을 방지할 수 있는 유용한 효과를 갖는다.According to the present invention configured as described above, the driving motor is driven simultaneously with the operation of the drain motor during the rinsing process of the centrifugal washing machine to execute intermittent dehydration and the main dewatering, or the driving motor simultaneously with the operation of the drain motor during the rinsing process. By running the rotor directly to the main dehydration, it is possible to perform a faster rinsing process to feel the operating time of the entire washing machine and evenly unloads the laundry stuck in the washing tank during the washing process to wash the inner tank during dehydration It has a useful effect that can prevent generation of vibration and noise by unbalance.
