본 발명은 정수 세탁기에 관한 것으로, 특히 정수장치의 정수필터 교체시점을 자동적으로 표시 할 수 있도록 한 정수세탁기의 필터교환시점 표시방법에 관한 것이다.The present invention relates to a water purifying washing machine, and more particularly, to a method of displaying a filter washing time of a water washing machine which is capable of automatically displaying the time of replacing the water purifying filter of the water purifying device.

종래의정수 세탁기는 제1도에 도시된 바와같이, 냉수 공급관(11)에 솔레노이드 밸브(12a, 12b)를 부착하고, 상기 냉수공급관(11)의 양단을 정수기(15)와 배수호스(3)에 연결하여형성하였다. 또한, 온수공급관(13)은 솔레노이드밸브(14a, 14b)를 부착하고, 상기 온수공급관(13)의 양단에 정수기(15)와 세제통(16)을 각각 부착하여 형성하엿다.In the conventional water washing machine, as shown in FIG. 1, the solenoid valves 12a and 12b are attached to the cold water supply pipe 11, and both ends of the cold water supply pipe 11 are provided with the water purifier 15 and the drain hose 3. Formed in connection with In addition, the hot water supply pipe 13 is formed by attaching the solenoid valve (14a, 14b), and attached to the water purifier 15 and the detergent container 16 on both ends of the hot water supply pipe (13).

이러한 종래의 정수세탁기는 솔레노이드밸브(12a)를 통해 급수되는 물을 솔레노이드밸브(12b)가 닫힌 상태에서 초기 몇초간 세탁수를 바이패스시켜 냉수공급관(15) 내부의 이물질을 배수호스(3)를 통해 외부로 배출시킨다. 냉수공급관(11)내의 이물질을 제거한 후 솔레노이드 밸브(12a, 12b, 14b)를 열어 세탁수를 공급하고, 이때 급수된 물은 정수기(15)와 세제통(16)을 거쳐 세탁조(2)로 공급된다. 정수기(15)의 수명을 연장하기 위하여 역세척시킬 경우 솔레노이드 밸브(14a)를 잠그로 솔레노이드밸브(12a, 14b)를 열어서 역세척을 실시한다.This conventional water washing machine bypasses the washing water for a few seconds while the solenoid valve 12b is closed to supply water supplied through the solenoid valve 12a to drain foreign matter inside the cold water supply pipe 15 to the drain hose 3. Through the outside. After removing foreign substances in the cold water supply pipe 11, the solenoid valves 12a, 12b, and 14b are opened to supply washing water, and the water supplied is supplied to the washing tank 2 through the water purifier 15 and the detergent container 16. . In the case of backwashing to extend the life of the water purifier 15, the solenoid valves 14a are closed to open the solenoid valves 12a and 14b to perform backwashing.

이러한 정수기(15)세척에도 불구하고 세탁기의 장기사용으로 정수기(15)의 필터에는 이물질이 누적되어 일정기간 후 정수기(15)로서의 기능을 상실하게 되고, 따라서 일정량의 이물질이 정수기(15)의 필터에 쌓인 경우 신속하게 필터를 교체하여야 한다.Despite the washing of the water purifier 15, foreign substances accumulate in the filter of the water purifier 15 due to long-term use of the washing machine, and the function of the water purifier 15 is lost after a certain period of time. If accumulated, the filter should be replaced quickly.

그러나, 일반사용자들은 정수기(15)의 필터교체시점을 육안으로 식별하거나 주관적판단 에 의존하여 필터를 교환함으로서 사용가능한 필터를 조기에 교체하는 폐단이 발생되었다.However, the general users have a short time to replace the available filter early by visually identifying the filter replacement time of the water purifier 15 or by replacing the filter depending on the subjective judgment.

또한, 필터교환시점을 지난 경우, 필터의 막힘으로 인하여 세탁시간의 연장등 문제점이 발생되었다.In addition, when the filter replacement time has passed, problems such as an extension of the washing time due to clogging of the filter have occurred.

따라서, 본 발명은 상기한 문제점을 해소하기 위하여 창안한 것으로, 그 목적은 정수기의 필터교환시점을 셋팅하여 정확하게 표시하도록 하므로서 일반 사용자가 적절한 시점에서 정수기 필터를 교환 할 수 있도록 한 정수세탁기의 필터교환시점 표시방법을 제공하는데 있다.Therefore, the present invention has been devised to solve the above problems, and its purpose is to set the filter replacement time of the water purifier and display it accurately so that the ordinary user can replace the water purifier filter at an appropriate time. The present invention provides a method of displaying a viewpoint.

위와같은 목적을 달성하기 위하여 본 발명의 실시예를 상세히 설명하면 다음과 같다.When explaining the embodiment of the present invention in detail to achieve the above object is as follows.

본 발명은 제2도에 나타낸 바와같이, 냉온수를 공급하는 정수 장치부(10)를 세탁기 본체(1)상부에 장치하고, 세탁기 본체(1)외면에 경보장치(20)를 부착하여, 정수 급수시간(tp)과 수도수 급수간(ti)의 값을 비교하도록 함을 기술적 특징으로 한다.According to the present invention, as shown in FIG. 2, a water purifier 10 for supplying cold and hot water is installed on the washing machine main body 1, and an alarm device 20 is attached to the outer surface of the washing machine main body 1 to supply purified water. It is a technical feature to compare the value of time (tp) and the tap water feed water ti.

상기, 정수장치부(10)는 냉수공급관(11)과 온수공급관(13)을 병열로 형성하고, 양단부를 정수기(15)와 세제통(16)에 각각 연통되도록 한다. 또한, 병열로 형성된 냉수공급관(11)과 온수 공급관(13)의 각각에 솔레노이드 밸브(12a, 12b와 14a, 14b)를 부착하여 온, 냉수의 흐름을 조절하도록 한다.The water purifier 10 forms the cold water supply pipe 11 and the hot water supply pipe 13 in parallel, and both ends thereof communicate with the water purifier 15 and the detergent container 16, respectively. In addition, the solenoid valves 12a, 12b and 14a and 14b are attached to each of the cold water supply pipe 11 and the hot water supply pipe 13 formed in parallel to adjust the flow of hot and cold water.

경보장치(20)는 소리 또는 육안 식별이 가능한 것으로 스피커 또는 발광 다이오드를 사용하는 것이 바람직하다.The alarm device 20 may use a speaker or a light emitting diode to identify sound or visually.

또한, 본 발명은 제3도에 나타낸 바와같이, 세탁조건을 선택하는 단계(A단계)와, 정수장치를 통하여 기준수위까지 급수하는 정수급수시간을 측정하는 단계(B단계)와, 상기 정수장치를 거치지 않고 기준수위까지 급수하는데 걸리는 수도수급수시간을 측정하는 단계(C단계)와, 이후 상기 정수급수시간에 대한 상기 수도수급수시간을 비교하는 단계 및 상기 비교값이 설정치 이하이면 필터교환을 알리는 단계 및 상기 비교값이 설정치 이상이면 행정을 계속 진행하는 단계(D단계)를 포함하여 이루어짐을 특징으로 한다.In addition, the present invention, as shown in Figure 3, the step of selecting the washing conditions (step A), the step of measuring the water supply time to supply water to the reference water level through the water purification device (step B), and the water purification device Measuring the water supply time required to supply water to the reference water level without passing through (step C), and then comparing the water supply time with respect to the water supply time, and if the comparison value is less than or equal to the set value, filter replacement is performed. And a step of notifying and continuing the process (step D) if the comparison value is greater than or equal to the set value.

한편, 제3도와 제4도에 나타낸 바와같이, 사용자가 퍼지 코스 또는 세탁물의 종류에 따른 수동코스를 선택하는 코스선택행정(A)은 일반적인 종래 세탁기와 동일하다.Meanwhile, as shown in FIG. 3 and FIG. 4, the course selection administration A in which the user selects the manual course according to the type of the purge course or the laundry is the same as the general conventional washing machine.

그리고 사용자의 정수기능 선택에 따른 세탁을 위한 정수기능실행부(B)는 정수기능이 없을 때에는 일반적인 세탁, 행굼 및 탈수의 행정을 실행하고, 정수기능이 있을 때에는 정수기(15)와 연결된 밸브(12b, 14a)를 통해 수도수를 정수기(15)에 공급 하므로서, 수도수를 정수하여 세탁조(2)에 공급한다. 또한, 정수기능실행부(B)는 급수기간이 카운터 될 수 있도록 하는 카운트부(a1)를 구비한다.The water purifying function execution unit (B) for washing according to the user's water purifying function selection performs a general washing, rinsing, and dehydration stroke when the water purifying function is not provided, and the valve 12b connected to the water purifier 15 when the water purifying function is provided. , 14a) by supplying tap water to the water purifier 15, the tap water is purified and supplied to the washing tank (2). The water purification function execution unit B also includes a count unit a1 for allowing the water supply period to be countered.

한편, 헹굼을 위한 수도수공급실행부(C)는 정수기능을 포함한 세탁 행정을 실행한 후 헹굼을 위해 정수기(15)와 별도로 연통되어 수도수를 공급하는 밸브(12a, 14b)를 조작하는 밸브선택부와 급수시간을 카운터하는 별도의 카운터부(a2)를 구비한다.On the other hand, the tap water supply execution unit (C) for rinsing after performing a washing stroke including a water purification function is in communication with the water purifier 15 separately for rinsing to operate the valve (12a, 14b) for supplying tap water A separate counter part a2 for countering the selection part and the water supply time is provided.

이와같은 본 발명을 보다 상세히 설명하면, 세탁코스가 선정되면 각각의 코스별 초기 조건이 셋팅되고, 정수기능 선택시 냉수, 온수 또는 냉온수혼합수가 공급된다. 이때, 밸브(12a, 14b) 또는 밸브(12a, 14b)가 열리고, 세탁조(2)에 급수가 완료되면 정수기(15)로 수도수가 유입된다.When the present invention is described in more detail, when the washing course is selected, the initial conditions for each course are set, and cold water, hot water, or cold / hot water mixed water is supplied when the water purification function is selected. At this time, the valves 12a and 14b or the valves 12a and 14b are opened, and when the water supply to the washing tank 2 is completed, tap water flows into the water purifier 15.

정수기(15)에 유입된 수도수는 필터링되어 세제통(16)을 거쳐 세탁조(2)에 정수를 공급한다. 이때, 세탁조(2)의 기준 수위까지의 급수시간이 카운터부(a1)에 의해 카운터되고, 급수 완료후 급수시간(tp)을 메모리한다. 세탁행정이 종료되면 탈수후 헹굼행정으로 진행된다. 한편, 헹굼을 위한 냉수, 온수 또는 냉온수혼합수를 공급여부가 선택되고 비정수 급수(헹굼시)가 진행된다. 이때, 기준수위까지의 비정수된 세탁수의 급수시간이 카운터부(a2)에 의해 카운터되고, 헹굼행정이 종료된다. 이후 탈수행정을 거쳐 세탁이 완료된다.The tap water flowing into the water purifier 15 is filtered to supply purified water to the washing tank 2 via the detergent container 16. At this time, the water supply time to the reference water level of the washing tank 2 is countered by the counter part a1, and memorizes the water supply time tp after completion of water supply. After the wash administration is finished, the process proceeds to rinsing after dehydration. Meanwhile, whether or not to supply cold water, hot water or cold / hot water mixed water for rinsing is selected, and the non-integer water supply (when rinsing) is performed. At this time, the water supply time of the non-purified washing water up to the reference water level is countered by the counter a2, and the rinsing cycle is finished. After the dehydration administration, the washing is completed.

따라서 세탁을 위한 정수급수시간(tp)과 헹굼을 위한 수도수급수시간(ti)를 비교하면 제4도에 나타낸 바와같이, 세탁횟수가 많을수록 정수급수시간이 증가하는 현상이 나타난다.Therefore, when the water supply time (tp) for washing and the water supply time (ti) for rinsing are compared, as shown in FIG. 4, as the number of washing times increases, the water supply time increases.

그러므로 정수기(15)의 필터에 이물질이 잔류하여 수도수의 흐름이 원할하지 못하여 최초 정수급수시간(tp)보다 세탁횟수가 많을수록 점점 정수급수시간(tp)이 길어진다.Therefore, foreign matter remains in the filter of the water purifier 15, so that the flow of tap water is not desired, and the more the number of washing times than the initial water supply time tp, the longer the water supply time tp becomes.

또한, 수도수급수시간(ti)은 항상 일정하므로써 수도수급수시간(ti)/정수급수시간(tp)를 설정하여 설정값이 “X”이하일 때 필터교환 장치를 작동시켜 경보장치(20)로 디스플레이 한다.In addition, since the water supply and demand time ti is always constant, the water supply and demand time ti and the water supply and demand time tp are set so that the filter change device is operated when the set value is equal to or less than “X” to the alarm device 20. Display.

그리고 세탁행정에 있어서 다음과 같이 급수가 여러번 반복된다.In the washing administration, water is repeated several times as follows.

급수(tp계산)→세탁→탈수→급수(ti계산)→비교판단→헹굼진행 또는 필터교환 알림Water supply (tp calculation) → washing → dewatering → water supply (ti calculation) → comparison judgment → rinse progress or filter replacement

이상에서 살펴본 바와같이 본 발명은 일반사용자의 육감에 의한 필터 교환에 따른 정수 필터의 낭비 및 급수시간 지연을 방지한 것이다.As described above, the present invention prevents wastewater and delay of water supply time due to filter replacement by the general user's sixth sense.
