본 발명은 세탁기에 관한 것으로서, 더욱 상세하게는 재급수 횟수를 통해 배수 동기 모터에 이물질이 끼인 것을 체크할 수 있도록 한 세탁기 누수 확인 방법에 관한 것이다. The present invention relates to a washing machine, and more particularly, to a washing machine leak check method to check that the foreign matter stuck to the drain synchronizing motor through the number of re-feeding.

최근 세탁기의 자동화가 진보되어, 세탁과정 수행 초기에 세탁조에 투입된 의류 등의 포량에 따라 기 설정된 프로그램으로 최적한 물 흐름, 세제, 헹굼, 및 탈수행정을 예정된 수순대로 진행하여 세탁물을 깨끗이 세탁하도록 하고 있다. Recently, the automation of the washing machine has been advanced, and according to the amount of clothes, etc. put into the washing tank at the beginning of the washing process, the optimal water flow, detergent, rinsing, and dehydration process are carried out in a predetermined sequence to wash the laundry cleanly. have.

이와 같은 일반적인 세탁기의 운전 제어는 통상적으로 세탁조에 투입된 의류 등의 포량을 감지하여 포량이 판정되면 그 포량에 따라 물 흐름과 세제 및 전체 세탁시간을 설정하고 전체 세탁시간 동안 펄세이터의 반전 회전을 통해 물을 와류시켜서 세탁물과의 마찰로 세탁물에 묻은 때를 분리하는 세탁행정, 세탁행정 후 혼탁한 물을 배출시키고 급수밸브를 통해 세탁조에 새로운 물을 공급하여 설정된 횟수동안 헹굼을 진행하는 헹굼행정, 헹굼행정 후 세탁조 내의 물을 배출하고 유동전동기를 고속으로 회전시켜 세탁물의 물기를 원심분리식으로 제거하는 탈수행정의 수순으로 수행된다.In general, the operation control of a washing machine generally detects a quantity of clothes, etc. put into a washing tank, and when a quantity is determined, sets water flow, detergent, and total washing time according to the quantity, and then reverses rotation of the pulsator for the whole washing time. Washing stroke which separates the time when it is stuck to the laundry by vortexing the water by vortexing water, draining turbid water after washing stroke, supplying fresh water to the washing tank through the water supply valve and rinsing for the set number of times. After the stroke, the water in the washing tank is discharged, and the flow motor is rotated at a high speed to carry out the dehydration process of centrifugally removing water from the laundry.

이러한 세탁기에 있어서, 세탁초기나 세탁행정 중에 결정된 수위로 급수가 완료되면, 세탁기는 사용자의 임의로 설정된 운전행정이나, 자동설정에 의하여 세탁을 진행하도록 되어 있어, 가령 이물질이나 기타 동전이 끼어 있거나 혹은 세탁 도중 세탁물로부터 분리된 이물질이나 동전이 끼게 되는 경우 세탁기는 급수시 급수되는 세탁수의 량이 누수되는 량보다 많기 때문에 결정된 수위로 일단 급수가 완료되면 누수에 관계없이 계속해서 세탁을 진행하도록 되어 있어, 세탁시간이 경과할 수록 세탁수가 적어지게 되어 세탁이 제대로 되지 않는 경우가 발생한다.In such a washing machine, when water supply is completed at the level determined during the initial washing or during the washing administration, the washing machine is configured to perform washing by a user's arbitrarily set driving stroke or automatic setting, so that foreign matters or other coins are stuck or washed. If foreign matters or coins separated from the laundry are caught, the washing machine has more water than the amount of water leaked when water is supplied, so once the water supply is completed, washing will continue regardless of water leakage. As time passes, the number of washing water decreases, and washing may not be performed properly.

그러므로, 종래에는 세탁중에 세탁수위를 감지하여 이 감지된 세탁수가 결정된 수위보다 한 단계이하로 떨어지게 되면, 누수가 발생된 것으로 판단하여 급수밸브를 열어 재급수하고, 이 재급수되는 수위를 감지하여 급수되는 수위가 상승하지 않으면 누수가 크게 발생되는 것으로 에러 경보를 발하였다. Therefore, conventionally, when the washing water level is sensed during washing and the detected washing water falls below one level below the determined water level, it is determined that a leak has occurred, and the water supply valve is opened to be resupplied, and the water supply level is detected to detect the water supply. If the water level does not rise, the water leakage is large and an error alarm is issued.

반면에, 재급수되는 수위가 상승하게 되면, 정상으로 판단하면서 세탁을 진행하고, 다시 수위가 낮아지면 다시 재급수하면서 세탁을 하도록 되어 있어, 배수구에 누수가 발생되었을 경우 탈수 외에는 세탁 및 헹굼시 많은 량의 물을 낭비할 뿐만 아니라, 세탁시간이 길어져 불필요한 전력을 낭비하면서 세탁 및 헹굼을 하게 되는 문제점이 있었다. On the other hand, when the water level to be resupplied rises, the washing process is judged to be normal, and when the water level is lowered again, the washing is re-supplied again to wash the water. Not only wasting a large amount of water, there was a problem in that the washing and rinsing while the washing time is long to waste unnecessary power.

따라서, 수위를 계속적으로 체크하여 실시간으로 사용자에게 통보하여 상기한 문제점을 미연에 방지할 필요성이 있었다.Therefore, there is a need to continuously check the water level and notify the user in real time to prevent the above problems in advance.

본 발명은 전술한 문제점을 해결하기 위해 안출된 것으로서, 재급수 횟수를 통해 배수 동기 모터에 이물질이 끼인 것을 체크할 수 있도록 한 세탁기 누수 확인 방법을 제공하는 데 그 목적이 있다. An object of the present invention is to provide a washing machine leak check method to check that the foreign matter is stuck in the drainage synchronous motor through the number of re-feeding.

본 발명의 다른 목적은 누수에 의한 불필요한 전력낭비와 세탁수 낭비를 미연에 방지하는 데 있다. Another object of the present invention is to prevent unnecessary power waste and washing water waste due to leakage.

전술한 목적을 달성하기 위해 안출된 본 발명의 구성은 다음과 같다. 본 발명은 세탁기의 세탁행정시에 배수동기 모터에 끼인 이물질에 의한 세탁조 내부의 누수를 확인할 수 있도록 하는 방법에 있어서, 세탁조 내부의 수위를 체크하여 초기 설정된 기준수위 이하인 지를 판단하는 제1단계, 기준수위 이하이면 재급수를 실시함과 더불어 재급수 횟수를 카운트하는 제2단계, 및 재급수 횟수가 기 설정된 기준횟수 이상이면, 배수동기 모터에 이물질이 끼여 있음을 사용자가 인식하도록 에러를 출력하는 제3단계를 포함하여 이루어지는 것을 특징으로 한다.The configuration of the present invention devised to achieve the above object is as follows. The present invention provides a method for checking the leakage of the inside of the washing tank due to the foreign matter caught in the drainage synchronous motor during the washing operation of the washing machine, the first step of determining whether the water level inside the washing tank is below the initial reference level If the water level is lower than the second step of re-watering and counting the number of re-watering, and if the number of times of re-watering is more than the preset reference number, the second step of outputting an error so that the user recognizes that foreign matter is caught in the drain synchronous motor Characterized in that it comprises three steps.

여기서, 상기 에러는 세탁기의 패널을 통해 디스플레이되거나 음성을 통해 출력되는 것을 특징으로 한다.Here, the error is characterized in that it is displayed through the panel of the washing machine or output through a voice.

이하에서는 본 발명의 바람직한 실시예를 첨부된 도면을 참조하여 상세하게 설명한다. Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail.

도 1 은 본 발명에 따른 세탁기 누수 확인 장치의 블럭 구성도이고, 도 2 은 본 발명에 따른 세탁기 누수 확인 방법의 순서도이다. 1 is a block diagram of a washing machine leak check apparatus according to the present invention, Figure 2 is a flow chart of a washing machine leak check method according to the present invention.

본 발명에 따른 세탁기 누수 확인 장치는 도 1 에 도시된 바와 같이, 마이컴(10)의 제어신호에 따라 온/오프되어 세탁조 내부로 세탁수를 급수하는 급수뱅브 (20), 세탁조 내부의 세탁수 수위를 감지하는 수위 센서(30), 배수 동기 모터에 이물질이 끼여 에러가 발생함을 출력하여 사용자가 에러 상황을 인지할 수 있도록 하는 경고출력부(40), 및 본 발명에 따른 세타기 누수 확인 장치를 전반적으로 제어하는 마이컴(10)으로 이루어진다. Washing machine leak check device according to the present invention, as shown in Figure 1, on / off according to the control signal of the microcomputer 10 to supply the washing water into the washing tank 20, the washing water level inside the washing tank Water level sensor 30 for detecting the error, the warning output unit 40 for outputting that an error occurs by the foreign matter is caught in the drainage synchronous motor, so that the user can recognize the error situation, and thetata leak check device according to the present invention It consists of the microcomputer 10 to control the overall.

여기서, 경고출력부(40)는 세탁기 패널에 설치되는 디스플레이부나 별도의 부져를 포함한다. Here, the warning output unit 40 includes a display unit or a separate buzzer installed in the washing machine panel.

마이컴(10)은 세탁행정시 시작되면, 수위 센서(30)가 감지한 세탁조의 수위를 통해 현재 세탁수가 누수되고 있는 지를 체크하고, 기준수위 미만인 경우에는 급수밸브(20)에 제어신호를 출력하여 이 급수밸브(20)를 통해 재급수가 이루어지도록 한다. When the microcomputer 10 starts at the washing administration, the water level sensor 30 checks whether the washing water is leaked through the level of the washing tank sensed, and if the level is less than the reference level, the microcomputer 10 outputs a control signal to the water supply valve 20. Re-water supply is made through this water supply valve 20.

이 때, 재급수 횟수를 카운트하여, 상기한 재급수 횟수가 기 설정된 기준횟수 이상인 지를 판단하여 상기한 기준횟수 이상이면, 상기한 경고 출력부(40)를 통해 사용자에게 에러 상황을 출력한다. At this time, the number of refills is counted, and it is determined whether the number of refills is greater than or equal to a preset reference number. If the number of refills is equal to or more than the reference number, the error condition is output to the user through the warning output unit 40.

다음은 상기한 구성을 통한 세탁기 누수 확인 방법을 도 2 를 참조하여 설명한다. Next, a method of checking a washing machine leak through the above configuration will be described with reference to FIG. 2.

본 발명에 따른 세탁기 누수 확인 방법은 세탁행정시 급수 밸브를 통해 급수된 세탁수를 실시간으로 계속적으로 수위를 확인하고, 상기한 수위가 초기 설정된 기준수위 이하이면 재급수를 실시하면서 그 재급수 횟수를 카운트하여 상기한 재급수 횟수가 기 설정된 기준횟수 이상이면 에러를 디스플레이하여 사용자가 현재 에러가 발생하였음을 인식할 수 있도록 한 것을 특징으로 한다. Washing machine leak check method according to the present invention checks the water level continuously in real time for the wash water supplied through the water supply valve during the washing administration, and if the water level is below the initial reference level set the water refilling water When the counted number of refills is greater than or equal to the preset reference number, an error is displayed to allow the user to recognize that a current error has occurred.

상세히 설명하면, 본 발명에 따른 세탁시 누수 확인 방법은 세탁행정시 수위를 체크(S10)하여 상기한 수위가 세탁 초기 설정된 기준수위 이하인 지를 판단(S20)하여 수위가 기준수위를 초과하는 경우에는 현재 진행되는 세탁행정을 계속적으로 진행(S25)한다. In detail, the method of checking leakage during washing according to the present invention checks the water level during the washing administration (S10) to determine whether the water level is lower than the reference level set at the initial stage of washing (S20). The ongoing washing administration proceeds (S25).

반면에, 수위가 세탁 초기 설정된 기준수위 이하인 경우에는 급수밸브를 온시켜 세탁조 내부로 세탁수를 재급수(S30)한다. On the other hand, when the water level is lower than the reference level set in the initial washing, the water supply valve is turned on to resuppose the washing water into the washing tank (S30).

세탁수가 재급수되면, 세탁수가 재급수되는 횟수를 카운트(S40)하는데, 이 때, 재급수 횟수가 기 설정된 기준횟수 이상인 지를 판단(S50)한다. When the wash water is re-supplied, the number of times the wash water is re-supplied is counted (S40). At this time, it is determined whether the number of re-supplied water is equal to or more than the preset reference number (S50).

이 경우, 재급수 횟수가 기 설정된 기준횟수 미만인 경우에는 현재 진행되는 세탁행정을 계속적으로 진행(S25)하고, 재급수 횟수가 기 설정된 기준횟수 이상인 경우에는 배수 동기 모터에 이물질이 끼어 있음을 사용자가 인식할 수 있도록 상기한 에러 사항을 출력(S60)한다. In this case, when the number of refilling water is less than the preset reference number, the washing administration currently proceeds continuously (S25). When the number of refilling water is more than the preset reference number, the user is informed that foreign matter is caught in the drainage synchronous motor. The above-mentioned error items are outputted so as to be recognized (S60).

출력 방법은 사용자가 세탁기의 패널에 설치되는 디스플레이부를 통해 디스플레이하도록 함과 더불어, 별도의 부져를 통해 경고음을 발생시킴으로써, 사용자가 세탁기에 인접해 있지 않더라도 에러 발생 사실을 인지할 수 있도록 한다. The output method allows the user to display through the display unit installed in the panel of the washing machine, and also generates a warning sound through a separate buzzer, so that the user can recognize the fact that an error occurs even if the user is not adjacent to the washing machine.

본 발명은 전술한 실시예에 국한되지 않고 본 발명의 기술사상이 허용하는 범위 내에서 다양하게 변형하여 실시할 수 있다. The present invention is not limited to the above-described embodiments and can be carried out in various modifications within the scope of the technical idea of the present invention.

이와 같이 구성되는 본 발명에 따르면, 재급수 횟수를 통해 배수 동기 모터 에 이물질이 끼인 것을 체크하여 사용자가 누수를 쉽게 확인할 수 있도록 함으로써, 불필요한 전력낭비나 세탁수의 낭비를 미연에 방지할 수 있다.According to the present invention configured as described above, by checking that the foreign matter is caught in the drainage synchronous motor through the number of re-feeding so that the user can easily check the leakage, unnecessary waste of power or waste of wash water can be prevented.
