Abstract

A mechanism for preventing unbalance during washing by controlling water flow depending on water level is provided. While in a washing cycle, the 40, 30, 25, or 20sec setting before the completion of a washing cycle is reached (Stage 21) depends on the water level(high, medium, low, minimum) sensed by the water-level sensor (Stage 20). When the set time is reached, the washing cycle proceeds according to a water-flow control time setting (0.7sec ON-0.5sec OFF, 0.6sec ON-0.4sec OFF, 0.5sec ON-0.4sec OFF, 0.3sec ON-0.4sec OFF respectively). While draining after the completion of the washing cycle, the water level is sensed (State 24). Except in the case when the water level is below minimum, the drain cycle proceeds according to a water-flow control time setting depending on the draining water level(high, medium, low, minimum) sensed.

본 발명은 세탁기의 언발란스 감지 방법에 관한 것으로, 특히 세탁종료 전에 수류제어를 수위에 따라 적절히 조절하여 언발란스발생을 방지하도록 한 세탁기의 언발란스 방지방법에 관한 것이다.The present invention relates to a method for detecting unbalance of a washing machine, and more particularly, to a method for preventing unbalance of a washing machine to prevent unbalance from occurring by appropriately adjusting the water flow control according to the level of water before end of washing.

일반적으로 세탁기에서 세탁시나 헹굼시 정,역회전하는 모터에 의하여 야기되는 수류마찰력으로 세탁조내의 세탁물은 엉킴이 생기면서 세탁조에 편심을 발생시키게 되고, 이 편심발생은 세탁시는 물론 탈수 시에 세탁조를 불균형하게 만들어 소음은 물론 구동부에 마모를 일으키게 된다.In general, when washing in a washing machine or rinsing, water in the washing tank is entangled with water friction caused by the motor rotating forward and reverse, causing eccentricity in the washing tank. This eccentricity causes the washing tank during washing and dehydration. Unbalance can cause noise and wear to the drive.

그러므로 종래 세탁기에서는 상기 세탁조의 불균형(언발란스)을 방지하는 방법으로 세탁종료 20초 전에 수위에 관계없이 수류시간(0.3초 온, 0.7초 오프)으로 운전으로 하여 세탁조 내의 세탁물의 편심 즉 세탁조의 언발란스를 방지하여 왔으나, 그러나 상기 방법은 수위에 관계없이 일률적으로 이루어져서 세탁물이 많은 고수위의 경우 수류가 약하여 전혀 효과를 기대할 수 없었다.Therefore, in the conventional washing machine, the washing machine is operated at a water flow time (0.3 sec on, 0.7 sec off) regardless of the water level 20 seconds before the end of washing in order to prevent the unbalance of the washing tank. Although it has been prevented, but the method is made uniformly regardless of the water level in the case of a high water level with a lot of laundry water flow is weak, could not expect any effect at all.

따라서 본 발명의 목적은 세탁종료 전에 언발란스를 방지하기 위하여 행해지는 수류제어를 수위에 따라 가변하면서 세탁을 하도록 함으로써, 세탁 및 헹굼시 언발란스 발생을 방지하도록 하고자 하는데 있다.Therefore, an object of the present invention is to prevent the occurrence of unbalance during washing and rinsing by washing the water flow control to be performed according to the water level to prevent unbalance before the end of washing.

상기의 목적을 실현하기 위하여 본 발명은 세탁종료 전에 수위를 감지하고, 이 감지된 수위에 따라 임의로 설정된 세탁종료 전시간에 설정하고, 이 설정된 시간에 따라 각각의 수류제어시간을 설정하여, 이 설정된 수류제어시간으로 세탁을 진행하는 단계와, 상기 단계에서 설정된 수류제어시간으로 세탁을 진행 중에 세탁이 완료되었는가를 판단하는 단계와, 상기 단계에서 세탁이 완료되었으면, 배수하고, 배수되는 수위를 감지하여 이 감지되는 수위에 따라 상기 임의로 설정된 수류제어시간으로 수류제어하면서 배수하고 완료하도록 한 것을 특징으로 한다.In order to realize the above object, the present invention detects the water level before the end of the washing, and set at the end of the washing time arbitrarily set according to the detected water level, and set the respective water flow control time according to this set time, Determining whether the washing is completed during the washing process in the water flow control time, and the water flow control time set in the step, and if the washing is completed in the step, drain, and detect the level According to the detected water level, the water flow is controlled and drained and completed by the arbitrarily set water flow control time.

이하 첨부된 도면에 의거 본 발명을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

A drainage level detecting step 24 of detecting the level of the water drained in step 23; The water level detection step 24 determines whether the water level is less than the very low water level determination step 25, and if the water level is less than the very low water level determination step 25, the detected water level The water flow is controlled by the arbitrarily set water flow control time corresponding to the water discharge control step 26 to drain until the drainage is completed.

상기와 같이 이루어지는 본 발명의 작용효과를 설명하면 다음과 같다.Referring to the effects of the present invention made as described above are as follows.

먼저, 세탁기에 전원을 인가하고 이어서 세탁하고자 하는 일련이 세탁행정에 대한 운전신호를 세탁운전입력부(가)를 통해서 상기 마이콤(나)에 입력하게 되면, 상기 마이콤(나)에서는 상기 입력된 세탁운전신호에 대하여 기설정된 소정의 프로그램에 의하여 제어하고 제어된 신호를 각 구동부에 출력하여 세탁을 진행하게 되는 바, 즉 상기 마이콤(나)에서는 세탁모터구동부(라)를 제어하여 세탁량에 따른 급수수위를 결정하고, 이어서 급배수구동부(라)를 제어하여 상기 결정된 수위로 급수한 후, 상기 세탁모터구동부(라)를 정,역회전 구동하면서 세탁을 진행하게 된다.First, when power is supplied to the washing machine and the series to be washed subsequently inputs a driving signal for the washing administration to the microcomputer (B) through the laundry driving input unit (A), the microcomputer (B) inputs the washing operation. The washing is controlled by a predetermined program with respect to the signal, and the controlled signal is output to each drive unit to perform washing. That is, the microcomputer (b) controls the washing motor driving unit to control the water supply level according to the washing amount. After determining and controlling the water supply and drainage part D, the water is supplied to the determined water level, and then washing is performed while the washing motor driver D is driven forward and backward.

상기와 같이 세탁을 진행하는 동안 상기 마이콤(나)에서는 세탁수위감지단계(20)로 가서 수위감지부(다)를 제어하여 진행 중인 세탁수를 감지하고, 이어서 상기 마이콤(나)에서는 세탁수류설정단계(21)로 가서 상기 감지된 수위가 고, 중, 저, 소, 극소에 따라 임의로 설정된 세탁종료 40초, 30초, 25초, 20초, 20초 전시간에 도달하였는가를 각각 판단하게 되는데, 상기 세탁종료 전시간을 수위에 따라 다르게 설정하는 것은 세탁수위가 높을 수록 세탁수류마찰력이 커서 그 만큼 세탁물의 엉킴이 크게 발생되기 때문에, 수위에 따라 세탁종료 전시간을 다르게 설정하게 되는 것이다.While the washing proceeds as described above, the microcomputer (b) goes to the washing water level detecting step 20 to control the water level sensing unit (c) to detect the washing water in progress, and then the washing water flow setting in the microcomputer (b). Going to step 21, it is determined whether the detected water level has reached the end of washing time 40 seconds, 30 seconds, 25 seconds, 20 seconds, 20 seconds, which is arbitrarily set according to the high, medium, low, small and very small. In order to set the total time for the end of washing differently according to the water level, the higher the washing water level, the greater the washing water friction and the greater the entanglement of the laundry.

그러므로 상기 세탁을 진행 중에 임의로 설정한 세탁종료 전시간에 도달하지 않았으면 계속해서 상기 임의로 설정된 세탁종료 전시간에 도달할 때까지 통상의 세탁수류제어시간에 의하여 세탁을 진행하고, 반면에 상기 진행 중인 세탁이 상기 수위에 따라 임의로 설정된 세탁종료 전시간에 도달하였으면, 상기 감지된 수위에 따라 상기 임의로 설정된 소정의 수류제어시간(0.7초온 0.5초오프, 0.6초온 0.4초오프, 0.5초온 0.4초오프, 0.3초온 0.4초오프)을 각각 설정하여 이 설정된 수류제어시간으로 세탁을 진행하게 되는데, 이 때도 수류제어시간을 다르게 하게 하는 것은 세탁량이 많고, 적음에 따라 수류마찰력이 달라지게 때문에 세탁시 세탁물의 엉킴 상태가 다르게 되기 때문에 엉킴 상태에 따라 용이하게 풀어주면서 세탁하기 위해서이다.Therefore, if the laundry does not reach the end time set arbitrarily arbitrarily set during the washing process, the laundry is continued by the normal washing water flow control time until the randomly set end time of washing is reached. When the washing reaches the washing end time set arbitrarily according to the water level, the predetermined water flow control time according to the detected water level (0.7 second temperature 0.5 second off, 0.6 second temperature 0.4 second off, 0.5 second temperature 0.4 second off, 0.3 Washing proceeds with this set water flow control time by setting the temperature of 0.4 sec. Off each time.In this case, the water flow control time is different because the amount of washing is large, and the water flow friction is changed according to the small amount. Is different because it is easy to loosen and wash according to the tangle.

이와 같이 수위에 따라 세탁종료 전시간 및 수류제어시간을 달리하면서 세탁을 진행 중에 상기 마이콤(나)에서는 세탁이 완료되었는가를 판단하게 되고, 이 때 판단결과 세탁이 완료되지 않았으면 수위감지단계(20)로 부터 세탁이 완료될 때까지 임의로 설정된 수류제어시간으로 세탁을 진행하고, 상기 판단결과 세탁이 완료되었으면 상기 마이콤(나)에서는 오염된 세탁수를 배수하기 위하여 배수단계(23)로 가서 급배수구동부(라)를 제어하여 배수구(도시하지 않음)를 열어 상기 오염됨 세탁수를 배수함과 아울러 상기 마이콤(나)에서는 배수수위감지단계(24)로 가서 수위감지부(다)를 제어하여 진행 중인 배수수위를 감지하게 되고, 이어서 극소수위이하판단단계(25)로 가서 상기 감지된 배수수위가 극소수위 이하인가를 판단하게 되고, 이 때 상기 감지된 배수수위가 극소수위가 아니면, 배수수류제어단계(26)로 가서 상기 감지된 배수수위(고,중,저,소)에 따라 그에 해당하는 수류제어시간(0.7초온 0.5초오프, 0.6초온 0.4초오프, 0.5초온 0.4초오프, 0.3초온 0.4초오프)을 각각 설정하고, 이 설정된 수류제어시간으로 상기 세탁모터구동부(마)를 제어하여 펄세이터를 정,역회전시키면서 상기 세탁시 발생된 세탁물의 엉킴을 풀어 주면서 배수가 완료될 때까지 배수를 하게 되는 것이다.In this way, while the washing is in progress while changing the washing end time and the water flow control time according to the water level, the microcomputer (b) determines whether the washing is completed. At this time, if the washing is not completed, the water level detection step 20 Proceeds to the water flow control time arbitrarily set until the washing is completed from the), and if the washing is completed as the result of the determination, the microcomputer (b) goes to the draining step 23 to drain the contaminated washing water. Control the eastern part (D) to open a drain (not shown) to drain the contaminated wash water, and at the microcomputer (B), go to the drainage level detection step 24 to control the level detection part C. The water level being used is sensed, and then the flow goes to the low level determination step 25 to determine whether the detected water level is less than the minimum level. If the drainage level is not very low, go to the drainage flow control step 26 and according to the detected drainage level (high, medium, low, small), the corresponding water flow control time (0.7 seconds 0.5 seconds off, 0.6 seconds 0.4 seconds) Off, 0.5 seconds on 0.4 seconds off, 0.3 seconds on 0.4 seconds off) and control the washing motor driving unit (e) at this set water flow control time to rotate the pulsator forward and reverse while Release the tangles and drain until the drainage is complete.

이상에서 설명한 바와 같이 본 발명은 세탁시 세탁량에 따라 결정된 수위로 세탁진행 중에 수위에 따라 세탁종료 전시간 및 수류제어시간을 임의로 설정하면서 세탁하고 완료하고, 배수시에도 배수시와 마찬가지로 배수수위에 따라 상기 임의로 설정된 수류제어시간으로 펄세이터를 회전시키면서 배수하도록 함으로써, 세탁시 수류마찰력으로 발생되는 엉킴을 풀어주게 되어, 세탁완료 후 세탁물의 엉킴에 의한 세탁조의 언발란스를 방지할 수 있는 효과를 제공하게 되는 것이다.As described above, the present invention washes and completes the washing end time and the water flow control time arbitrarily according to the water level during the washing process at the water level determined according to the amount of washing at the time of washing. By rotating the pulsator while the water flow control time is set arbitrarily, it releases the tangling caused by the water flow friction during washing, thereby providing the effect of preventing the unbalance of the washing tank by tangling the laundry after the completion of the washing will be.
