본 발명은 세탁기의 급수방법에 관한 것으로, 특히 수압이 낮은 지역에서 급수시 소정시간 동안에 급수 상태를 판단하면서 급수상태가 상승하게 되면, 설정된 급수수위까지 급수가 진행되게 하면서 정상세탁행정이 이루어지도록 한 세탁기의 급수방법에 관한 것이다.The present invention relates to a water supply method of a washing machine, and in particular, when the water supply state rises while determining the water supply state for a predetermined time during water supply in a region where the water pressure is low, the water supply proceeds to the set water supply level so that the normal washing administration is made. It relates to a water supply method of the washing machine.

종래 세탁기의 경우, 급수시 소정급수시간(20-30분)동안 소정의 수위(고, 중, 저, 소)까지 급수완료 되지 않으면, 급수에 이상이 있음을 경고하면서 세탁행정을 정지하도록 되어 있거나, 간혹 단수로 인하여 급수가 되지않을 경우, 또는 수압이 낮아 급수가 약하게 이루어지는 경우에 상기 소정시간 동안에 소정수위로 급수가 이루어지지 않게 되므로, 급수도중에 경보를 발생하면서 세탁동작을 하지 않도록 되어 있다.In the case of a conventional washing machine, if the water supply is not completed until the predetermined water level (high, medium, low, small) for a predetermined water supply time (20-30 minutes) during water supply, the washing administration is stopped while warning that there is a problem with the water supply. In some cases, when water is not supplied due to the water shortage, or when the water supply is low because the water pressure is low, the water is not supplied to the predetermined level during the predetermined time, so that the washing operation is not performed while generating an alarm during the water supply.

따라서 사용자는 세탁기의 급수에 이상이 없음에도 불구하고, 세탁기에 이상이 있는 것으로 판단하여 세탁기의 수리 서비스를 의뢰하는 등 세탁기의 이용에 불편함을 가지고 있었다.Therefore, although the user has no abnormality in the water supply of the washing machine, the user has an inconvenience in using the washing machine, such as requesting a repair service of the washing machine in consideration of the abnormality in the washing machine.

본 발명의 목적은 세탁기 급수상태를 소정시간 동안 감지하여 급수상태가 상승하고 있으면, 급수가 되고 있는 것으로 판단하여 설정된 수위까지 계속해서 급수가 이루어지도록 함으로써, 정상세탁이 이루어지도록한 급수방법을 제공하고자 하는데 있으며, 상기의 목적을 실현하기 위하여 본 발명은 급수가 시작되면, 급수상태를 감지하면서 소정의 급수시간 동안에 급수수위가 상승하고 있는가를 판단하는 단계와, 상기 단계에서 급수상태가 상승하고 있지 않으면, 소정의 급수시간이 완료되었는가를 판단하면서 급수시간이 완료되었으면, 급수이상을 경보하는 단계와, 상기 단계에서 급수상태가 상승하고 있으며, 기설정된 급수수위에 도달할때까지 계속해서 급수하면서 급수를 완료하도록 하는 단계로 이루어짐을 특징으로 한다.An object of the present invention is to provide a water supply method for the normal washing is performed by detecting the washing machine water supply state for a predetermined time, and if the water supply state is rising, it is determined that the water supply is to continue to supply the water to the set water level. In order to realize the above object, the present invention is to determine whether the water supply level rises during a predetermined water supply time while detecting the water supply state when the water supply is started, and if the water supply state is not rising in the step, If the water supply time is completed while judging whether the predetermined water supply time is completed, the water supply abnormality is alerted, and the water supply state is rising at the above step, and the water supply is completed while continuing to supply water until the preset water supply level is reached. It is characterized by consisting of steps to make.

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 인가한 상태에서, 사용자가 세탁을 하기 위하여 세탁기의 운전신호입력부(a)를 통해서 세탁하고자 하는 세탁운전에 대한 신호를 설정하여 마이콤(c)에 입력시키면, 상기 마이콤(c)에서는 상기 운전신호입력부(a)에서 입력된 신호를 기설정된 소정의 프로그램에 의하여 제어하면서 표시부(d)를 제어하여 설정된 세탁운전상태를 표시함과 아울러, 상기 마이콤(c)에서는 급수단계(20)로 가서 급수제어부(e)를 제어하여 급수밸브를 열어 급수를 하게 되는데, 이때 상기 마이콤(c)에서는 급수감지단계(21)로가서 수위감지부(b)를 제어하여 현재 세탁조에 급수되고 있는 급수수위상태를 감지하게 된다.First, when the power is supplied to the washing machine, the user sets a signal for the washing operation to be washed through the driving signal input unit (a) of the washing machine to perform the washing, and inputs the signal to the microcomputer (c). In the control signal display unit (d) while controlling the signal input from the operation signal input unit (a) by a predetermined program to display the set washing operation state, and in the microcomputer (c) water supply step 20 In order to control the water supply control unit (e) to open the water supply valve to supply water, in this case, the microcomputer (c) goes to the water supply detection step 21 to control the water level detection unit (b) to supply water to the current washing tank The water level is detected.

상기와 같이 급수상태를 감지하면서 상기 마이콤(c)에서는 급수시간경과판단단계(22)로 가서 현재 급수되고 있는 시간이 기설정된 소정의 급수시간이 경과하였는가를 판단하게 되고, 이때 소정의 급수시간이 경과하지 않았으면, 상기 마이콤(c)에서는 소정시간이 경과할때까지 상기 단계들을 반복수행하면 소정시간이 경과할때까지 급수를 하게 된다.While detecting the water supply state as described above, the microcomputer (c) goes to the water supply time elapsed judgment step 22 to determine whether a predetermined water supply time has elapsed since the current water supply time has elapsed. If it has not elapsed, the microcomputer (c) repeats the steps until a predetermined time elapses, and water is supplied until a predetermined time elapses.

이와 같이, 상기 소정의 급수시간이 경과할때까지 급수를 진행하고 있는 상태에서 상기 마이콤(c)에서는 급수수위상승판단단계(23)로 가서 상기 소정급수시간이 경과할때까지 급수수위상태가 상승하였는가를 판단하게 되고, 상기 급수수위상승판단단계(23)에서 급수수위가 상승을 하지 않았으면, 상기 마이콤(c)에서는 급수시간완료판단단계(24)로 가서 급수시간(20-30분)이 완료되었는가를 판단하게 되고, 판단결과 급수시간이 완료되지 않았으면 상기 마이콤(c)에서는 상기 급수단계(20)로부터 급수시간이 완료될때까지 반복 수행을 하게 되고, 이어서 상기 급수시간완료판단단계(24)에서 상기 소정의 급수시간이 완료가 되었음에 불구하고 급수수위가 상승하지 않았으면, 상기 마이콤(c)에서는 급수이상경보단계(25)로 가서 경보부(f)를 제어하여 급수상태에 이상이 있음을 사용자에게 경보하여 주게 된다.In this way, in the state where the water supply is in progress until the predetermined water supply time has elapsed, the microcomputer (c) goes to the water supply level increase determination step 23, and the water supply level state is increased until the predetermined water supply time has elapsed. If the water level is not increased in the water level rise determination step 23, the microcomputer (c) goes to the water supply time completion step 24, and the water supply time (20-30 minutes) is determined. If it is determined that the water supply time is not completed, the microcomputer (c) is repeatedly performed until the water supply time is completed from the water supply step 20, and then the water supply time completion determination step 24 If the water supply level does not rise even though the predetermined water supply time is completed, the microcomputer (c) goes to the water supply abnormality alarm step (25) and controls the alarm unit (f) to supply water. More than is granted to the user that the alarm.

그러나 상기 급수수위상승판단단계(23)에서 판단결과 급수수위가 상승한 것으로 판단되면 상기 마이콤(c)에서는 급수완료판단단계(26)로 가서 급수제어부(e)를 제어하여 계속해서 급수를 진행하여 기설정된 소정의 급수수위까지 급수가 완료되었는가를 판단하게 되며, 상기 급수를 상태를 판단한 결과 소정의 급수수위까지 급수가 완료되지 않았으면 상기 마이콤(c)에서 상기 급수단계(20)로부터 반복수행하면서 소정의 급수가 완료될때까지 급수를 하며 이어서 소정의 급수수위까지 급수가 완료되었으면 상기 마이콤(c)에서는 급수완료단계(27)로 가서 급수제어부(e)를 제어하여 급수를 중지하고, 이후 상기 운전신호입력부(a)에서 입력된 운전신호 상태로 세탁을 진행하게 되는 것이다.However, if it is determined that the water supply level has risen in the water level rise determination step 23, the microcomputer (c) goes to the water supply completion determination step 26 to control the water supply control unit e to continue to supply water. It is determined whether the water supply is completed up to the predetermined water supply level, and if the water supply is not completed to the predetermined water supply level as a result of judging the state of the water supply, the microcomputer (c) repeatedly performs the water supply step 20 while The water supply is supplied until the water supply is completed, and when the water supply is completed up to a predetermined water supply level, the microcomputer (c) goes to the water supply completion step 27 to control the water supply control unit e to stop the water supply, and then the operation signal. The washing is performed in the state of the driving signal input from the input unit (a).

이상에서 설명한 바와 같이, 본 발명은 세탁시 급수되는 급수수위상태를 소정의 시간 간격으로 급수상태를 감지하고 급수수위상태가 상기 소정의 시간 동안 상승을 하지 않았으면 급수상태에 이상이 있음을 경보하고 소정의 시간 동안 급수상태가 상승하였으면 급수상태에 이상이 없는 것을 판단하여 정상적인 세탁운전을 하도록 함으로써, 간혹 수압이 낮거나 일시적인 단수로 인하여 정상급수가 되지 않을 경우 야기되는 제반 문제점을 해소할 수 있는 효과를 제공하게 되는 것이다.As described above, the present invention detects the water supply state at a predetermined time interval for the water supply level supplied during washing, and alarms that there is an abnormality in the water supply state if the water supply level does not rise during the predetermined time. If the water supply state rises for a predetermined time, it is determined that there is no abnormality in the water supply state so that the normal washing operation can be performed, thereby providing an effect that can solve all problems caused when the water supply is not normal due to low water pressure or temporary water shortage. Will be done.
