The valve 20 includes a valve plate 22 and a rod 21 for opening and closing the water supply passage of the water supply valve 20. An example of a washing machine having such a water supply valve 20 is illustrated in FIG. 1.

The rod 21 is provided with a cushion at its end and is movable in a bushing provided through the solenoid 23, and the valve hole 22a is provided by an elastic member 25 provided at the rear end thereof. Force is applied to close the valve hole and the rod 21 is moved to the rear side so that the rod 21 in close contact with the valve hole 22a is spaced apart from the valve hole 22a. By applying power to the solenoid 23 provided to surround the outer circumferential surface, the magnetic force is generated in the solenoid 23 so that the rod 21 is pulled toward the solenoid 23.

상기와 같이 구성된 세탁기의 급수밸브(20)에 있어서, 급수밸브(20)를 통해 세탁기 내에 공급되는 용수 즉, 수도물에는 철 성분이나 기타의 이물질들이 포함되어 있을 수 있으며, 그 이물질들이 밸브판(22)의 밸브공(22a)에 끼이게 되어 급수가 되지않게 되고 이는 급수안됨 오류를 발생시키게 됨을 물론 급수가 지연되거나 급수밸브(20)가 고장을 일으키는 원인이 되었다.In the water supply valve 20 of the washing machine configured as described above, the water supplied to the washing machine through the water supply valve 20, that is, the tap water may contain iron or other foreign substances, and the foreign substances may be included in the valve plate 22. It is caught in the valve hole (22a) of the water supply does not become a water supply, which causes a water supply failure error, of course, the water supply is delayed or the water supply valve 20 causes a failure.

따라서 본 발명의 목적은 상기한 결점들을 해소하고, 급수과정 중간에 로드가 진동되게하여 밸브판에 충격을 가하여 밸브공에 끼인 이물질을 제거할 수 있는 과정을 수행되게하여 밸브공의 막힘을 방지할 수 있는 급수방법을 제공하는 데에 있다.Therefore, an object of the present invention is to solve the above-mentioned defects, and the rod is vibrated in the middle of the water supply process to impinge on the valve plate to perform a process that can remove the foreign matter caught in the valve hole to prevent clogging of the valve hole It is to provide a water supply method.

도면 표시와 같이, 본 발명에 따른 세탁기의 급수방법은 급수과정 중에 이물질 제거단계(S2)를 포함하고 있다.As shown in the drawing, the water supply method of the washing machine according to the present invention includes a step of removing foreign substances (S2) during the water supply process.

상기 급수과정은 솔레노이드(23)에 지속적으로 전기를 공급하여 로드(21)가 밸브공(22a)으로부터 이격된 상태 즉, 급수밸브(20)가 개방되어 용수가 저수조내에 공급되는 상태의 급수단계(S1)와, 솔레노이드(23)에 공급되는 전기를 순간적으로 반복적으로 온,오프시켜 로드(21)가 진동하여 밸브판(22)에 충격을 가하도록하므로써 밸브판(22)의 밸브공(22a)에 끼인 이물질이 밸브공(22a)으로부터 빠져나가게 하는 이물질 제거단계(S2)를 포함한다.In the water supply process, the electricity is continuously supplied to the solenoid 23 so that the rod 21 is spaced apart from the valve hole 22a, that is, the water supply valve 20 is opened so that water is supplied into the reservoir. S1) and the valve hole 22a of the valve plate 22 by turning on and off the electricity supplied to the solenoid 23 momentarily repeatedly so that the rod 21 vibrates and impacts the valve plate 22. It includes a foreign material removal step (S2) to let foreign matter caught in the valve hole (22a) to escape.

상기 급수단계(S1)와 이물질 제거단계(S2)는 교번적으로 수행되어지나, 상기 이물질 제거단계(S2)가 너무 자주 수행되거나 길어지게 되면 용수의 공급에 많은 시간이 소모되게 되므로 이물질제거단계(S2)에서는 3내지4회만 솔레노이드(23)에 공급되는 전기를 온,오프시키는 것이 적당하나 이는 밸브판(22)에 충분한 충격을 가하기에 충분한 횟수내에서 가변적인 것으로 이에 대한 상세한 설명은 생략한다.The water supply step (S1) and foreign matter removal step (S2) is carried out alternately, if the foreign material removal step (S2) is performed too often or longer, so much time is consumed in the supply of water to remove the foreign matter ( In S2), it is appropriate to turn on and off the electricity supplied to the solenoid 23 only three to four times, which is variable within a sufficient number of times to apply a sufficient impact to the valve plate 22 and a detailed description thereof will be omitted.

또한 상기 급수단계(S1)의 길이 즉, 급수시간을 너무 길게 하면 밸브공(22a)에 끼인 이물질이 수압에 의해 압착되어 이물질 제거단계(S2)를 수행하는 과정에서 이물질이 밸브공(22a)로부터 제거되어지지 못하게 되는 문제가 있으므로 급수단계(S1)의 수행 시간은 30초내지40초 정도가 적당하나 이또한 가변 가능한 것으로 이에 대한 구체적인 설명은 생략한다.In addition, if the length of the water supply step (S1), that is, the water supply time is too long, the foreign matter caught in the valve hole (22a) is compressed by the water pressure to remove the foreign matter from the valve hole (22a) in the process of performing the foreign matter removal step (S2) Since there is a problem that can not be removed, the execution time of the water supply step (S1) is suitable for about 30 seconds to 40 seconds, but this is also variable, and detailed description thereof is omitted.

이와 같은 급구과정을 다시 도 3을 참조하여 설명한다.This supply process will be described again with reference to FIG. 3.

도3에 도시한 바와 같이, 급수단계(S1)와 이물질제거단계(S2)는 교번적으로 수행되어지며, 그 순서는 다음과 같다.As shown in Figure 3, the water supply step (S1) and foreign matter removal step (S2) is performed alternately, the order is as follows.

급수밸브(20)에 전기가 공급 즉, 솔레노이드(23)에 전기가 공급되면 로드(21)가 탄성부재(25)의 압축력을 극복하고 밸브판(22)으로부터 후퇴되어 밸브공(22a)이 개방되며 이에 따라 용수가 저수조(11)내에 공급되어진다. 이와 같은 급수단계(S1)가 기설정된 급수시간을 경과하면 솔레노이드(23)에 공급된 전기는 순간적으로 온,오프되는 과정을 전술한 바와 같이 3내지 4회 반복하게 되고 이때 로드(21)는 솔레노이드(23)에 의한 인장력과 탄성부재(25)에 의한 반발력에 의해 진동하게되어 밸브판(22)에 충격을 가하게 되어 밸브공(22a)에 끼여진 이물질이 밸브공(22a)으로부터 제거하게 된다.When electricity is supplied to the water supply valve 20, that is, electricity to the solenoid 23, the rod 21 overcomes the compressive force of the elastic member 25 and is retracted from the valve plate 22 to open the valve hole 22a. Accordingly, water is supplied into the reservoir 11. When the water supply step S1 passes the preset water supply time, the electricity supplied to the solenoid 23 is repeatedly turned on and off three to four times as described above, and the rod 21 is the solenoid. Vibration is caused by the tensile force by 23 and the repulsive force by the elastic member 25 to impact the valve plate 22 so that foreign matter trapped in the valve hole 22a is removed from the valve hole 22a.

상기와 같은 이물질제거단계(S2)를 수행후 다시 급수단계(S1)를 수행하게되며, 이와 같은 급수단계(S1) 동안 미설명한 수위감지기는 저수조(11)내에 공급되는 용수의 수위를 지속적으로 감지하여 기설정된 수위(소,저,중,고)까지 용수가 공급되면, 급수밸브(20)에 공급되는 전기는 차단되어 용수의 공급이 완료된다.After performing the foreign matter removal step (S2) as described above, the water supply step (S1) is performed again. During this water supply step (S1), the water level sensor, which has not been described, continuously detects the water level of the water supplied in the reservoir 11. When water is supplied up to a predetermined level (small, low, medium, high), the electricity supplied to the water supply valve 20 is cut off to complete the supply of water.

이상과 같이 본 발명에 의하면, 급수밸브(20)의 개폐를 위해 로드(21)가 밸브판(22)에 충격을 가하여 밸브공(22a)에 이물질이 끼여 누적되는 것을 방지할 수 있으므로 밸브공(22a)에 이물질이 끼여 유로가 막힘으로 인한 급수안됨 오류의 발생을 방지함은 물론 밸브공(22a)의 막힘에 의한 급수밸브(20)의 고장을 예방할 수 있고, 또한 원활한 급수를 수행할 수 있는 효과가 제공된다.As described above, according to the present invention, since the rod 21 impacts the valve plate 22 for opening and closing of the water supply valve 20, foreign matter may be prevented from accumulating in the valve hole 22a and thus, the valve hole ( It is possible to prevent the water supply valve 20 from failing due to the blockage of the valve hole 22a, as well as to prevent the water supply failure due to a blockage of the flow path due to foreign substances in 22a). The effect is provided.
