본 발명은 세탁기의 급수제어방법에 관한 것으로, 특히 헹굼과정 수행시 단시간에 세탁수의 급수를 완료하게 하는 세탁기의 급수제어방법에 관한 것이다.The present invention relates to a water supply control method of a washing machine, and more particularly, to a water supply control method of a washing machine to complete the water supply of the washing water in a short time when performing the rinsing process.

종래의 세탁기 급수제어방법은 세탁과정 수행시에는 사용자의 입력에 의해 냉수 및 온수를 선택하여 공급하고, 헹굼과정 수행시에는 에너지의 효율성 문제로 인하여 냉수만 공급됨으로서 수압이 낮은 고지대등의 지역에서는 세탁기의 급수기간이 길어지게 되어 전체 세탁과정을 완료하는데 소요되는 시간 역시 길 수 밖에 없어, 사용자의 여가시간 감소 및 세탁기가 고장을 일으킨 것으로 오판하는 사례등 세탁기의 신뢰성을 저하시키는 문제점이 있다.In the conventional washing machine water supply control method, cold water and hot water are selected and supplied by a user input when the washing process is performed, and only cold water is supplied when the rinsing process is performed due to energy efficiency problems. As the water supply period becomes long, the time required to complete the entire washing process is also long, and thus, there is a problem of reducing the reliability of the washing machine, such as a decrease in the leisure time of the user and a case in which the washing machine malfunctions.

본 발명은 이러한 문제점을 해소하기 위하여 세탁기의 헹굼과정 수행시에 세탁수의 급수에 소요되는 시간을 측정하여 마이크로컴퓨터에서 설정한 소요시간이 경과할 경우에는 냉수뿐만 아니라 온수도 동시에 투입되게 하여 최단시간에 급수가 완료되게 함으로서 전체 세탁과정을 종료하는데 소요되는 시간을 경감시킴으로서 세탁기의 신뢰성을 향상하고 사용자의 여가 시간을 증대시켜 주는 세탁기의 급수제어방법을 제공하는데 그 목적이 있다.In order to solve this problem, the present invention measures the time required for the water supply of the washing water when performing the rinsing process of the washing machine, and when the required time set by the microcomputer has elapsed, not only cold water but also hot water are simultaneously inputted. It is an object of the present invention to provide a water supply control method of a washing machine that improves the reliability of the washing machine and increases the leisure time of the user by reducing the time required to complete the entire washing process by completing the water supply.

이러한 목적을 달성하기 위한 본 발명의 세탁기 급수제어방법은 마이크로컴퓨터의 제어에 의해 세탁과정을 종료한다음 헹굼과정의 수행시에서 세탁기의 급수제어방법에 있어서, 냉수만이 급수되는 단계와, 선택된 수위까지 급수되었는지 판단하는 단계와, 설정된 시간동안 선택된 수위까지 급수되지 않으면 냉수와 온수를 동시에 급수하고 선택된 수위까지 급수가 완료되었는지 판단하는 단계와, 선택된 수위까지 급수가 완료되면 급수를 정지하는 단계로 이루어져 최단시간 동안에 선택된 수위까지 급수 하는 것이다.Washing machine water supply control method of the present invention for achieving the above object is a water supply control method of the washing machine at the time of performing the rinsing process after the washing process is terminated by the control of the microcomputer, the step of supplying only cold water, Determining whether water is supplied to the selected level, supplying cold water and hot water at the same time if the water level is not supplied to the selected level for a predetermined time, and determining whether the water supply is completed up to the selected level, and stopping the water supply when the water supply to the selected level is completed. It is to water up to the selected water level in the shortest time.

이하 첨부된 도면에 의해 상세히 설명하면 다음과 같다.Hereinafter, described in detail by the accompanying drawings as follows.

제1도는 본 발명에 따른 마이크로컴퓨터의 제어 블럭도로서 헹굼과 정시에 세탁수가 급수되는데 소요되는 시간을 측정하는 타이머(2), 사용자의 입력에 의해 선택된 수위까지 세탁수가 급수되었는지를 판단하는 수위감지부(3), 세탁기의 상부에 설치되어 마이크로컴퓨터(1)의 제어를 받아 개·페 작용을 함으로서 세탁과정 및 헹굼과정시에 냉수가 급수되는 것을 조절하는 냉수급수밸브(4), 냉수급수밸브(4)의 측면에 위치하여 마이크로컴퓨터(1)의 제어를 받아 개·폐 작용을 함으로서 세탁과정 및 헹굼과정시에 온수가 급수되는 것을 조절하는 온수급수밸브(5), 세탁물을 좌·우로 교반시키는 동력을 발생하는 모터구동부(6), 그리고 세탁기의 각 부분을 제어하는 마이크로컴퓨터(1)로 구성되어 있다.1 is a control block diagram of a microcomputer according to the present invention, a timer (2) for measuring the time taken for rinsing and watering water on time, and a water level detection for determining whether the washing water is supplied to a level selected by a user input. The cold water supply valve 4 and the cold water supply valve which are installed at the upper part of the washing machine and control the supply of cold water during the washing process and the rinsing process by opening and closing under the control of the microcomputer 1. The hot water supply valve (5), which controls the supply of hot water during the washing and rinsing process by opening and closing under the control of the microcomputer (1), located at the side of (4), and stirring the laundry left and right And a microcomputer 1 for controlling each part of the washing machine.

제2도는 본 발명인 세탁기의 급수제어방법 흐름을 도시한 도면이다.2 is a view showing the flow of the water supply control method of the washing machine according to the present invention.

이와 같이 구성되는 본 발명의 세탁기의 급수제어방법의 동작과정을 제1도 내지 제2도에 의거하여 설명하면 다음과 같다.The operation of the water supply control method of the washing machine of the present invention configured as described above will be described with reference to FIGS. 1 to 2 as follows.

세탁과정을 완료후에 헹굼과정이 수행하고(단계 101), 마이크로컴퓨터(1)는 타이머(2)를 동작하고 에너지의 효율적 운용을 위하여 냉수급수밸브(4)만을 개방시켜 설정시간 동안 냉수만을 세탁기에 공급한 다음(단계 102) 수위감지부(3)의 감지에 의해 선택된 수위까지 급수되었는지를 판단한다.(단계 103)After the washing process is completed, a rinsing process is performed (step 101), and the microcomputer 1 operates the timer 2 and opens only the cold water supply valve 4 for efficient operation of energy. After supplying (step 102), it is determined whether the water level is supplied to the selected water level by the detection of the water level detecting unit 3 (step 103).

상기 과정후에 냉수의 공급이 원활하여 일정시간 동안에 선택된 수위까지 급수가 완료 되었다면 냉수급수밸브(4)를 차폐하여 급수를 정지하고, (단계 106) 모터구동부(6)을 동작하여 헹굼과정을 수행하며(단계 107), 만약 수압 저하등의 요인에 의해 냉수공급이 원활하지 못하여 설정시간동안 선택된 수위까지 급수되지 않았다면 마이크로컴퓨터(1)는 냉수급수밸브(4) 뿐만 아니라 온수급수밸브(5)를 동시에 개방시켜 단시간안에 선택된 수위까지 급수하고(단계 104) 선택된 수위까지 급수되었는지 다시 판단하여(단계 105) 선택된 수위까지 급수가 완료되게 한다음 냉수급수밸브(4) 및 온수급수밸브(5)를 차폐시키고(단계 106) 모터구동부(6)에 전원을 인가하여 헹굼을 하는 것이다.(단계 107)If the supply of cold water is smooth after the above process and water supply to the selected water level is completed for a predetermined time, the water supply is stopped by shielding the cold water supply valve (4), and the rinsing process is performed by operating the motor driving unit (step 106). (Step 107), if the cold water supply is not smooth due to the water pressure drop and the like, the microcomputer 1 not only supplies the cold water supply valve 4 but also the hot water supply valve 5 simultaneously. Open the water supply to the selected water level in a short time (step 104) and re-determine whether the water supply is up to the selected water level (step 105) to complete the water supply to the selected water level and then shield the cold water supply valve 4 and the hot water supply valve 5 (Step 106) Rinsing is performed by applying power to the motor driver 6 (step 107).

이상에서 상술한 바와같이 본 발명의 세탁기의 급수 방법에서는 헹굼동작수행시에 세탁수가 공급되는 시간을 측정하여 설정시간이 초과하면 냉수급수밸브 및 온수급수밸브를 동시에 동작시켜 최단시간동안 세탁수가 급수되도록 함으로써, 세탁에 소요되는 시간을 경감하여 사용자의 여가시간을 증대시키고 세탁기의 급수에 대한 사용자의 신뢰성을 향상시키는 장점이 있다.As described above, in the water supply method of the washing machine of the present invention, when the washing water is supplied at the time of performing the rinsing operation, when the set time is exceeded, the cold water supply valve and the hot water supply valve are operated simultaneously so that the washing water is supplied for the shortest time. Thereby, there is an advantage of reducing the time required for washing to increase the leisure time of the user and improve the user's reliability of the water supply of the washing machine.
