본 발명은 식기세척기에 관한 것으로서, 특히 식기세척기의 과급수 제어방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dishwasher, and more particularly, to a supercharged water control method of a dishwasher.

일반적으로, 식기세척기에는 도 1에 나타낸 바와 같이, 그 내부에 식기가 놓이는 상부랙(17) 및 하부랙(18)이 각각 설치되는 터브(1)와, 상기 터브(1) 하부에 설치되며 식기를 세척하는데 사용되는 세척수가 저장되는 섬프(2)(sump)와, 상기 섬프(2)에 연결되어 섬프(2)에 저장된 세척수를 펌핑하여 상·하부 분사아암(3a)(3b)으로 압송하는 세척펌프(15)와, 상기 세척펌프(15)에 연결되어 세척펌프(15)의 펌핑작용에 의해 압송된 세척수를 상부랙(17) 및 하부랙(18)에 놓인 식기쪽으로 분사하는 상부 분사아암(3a)(spray arm) 및 하부 분사아암(3b)이 구비된다.In general, as shown in FIG. 1, the dishwasher includes a tub 1 having upper racks 17 and a lower rack 18 on which tableware is placed, and a dish disposed below the tub 1. The sump (2) (sump) to store the wash water used to wash the water, and the washing water stored in the sump (2) connected to the sump (2) to pump the upper and lower injection arms (3a) (3b) The upper injection arm connected to the washing pump 15 and the washing pump 15 and spraying the washing water pumped by the pumping action of the washing pump 15 toward the tableware placed on the upper rack 17 and the lower rack 18. (3a) (spray arm) and the lower injection arm (3b) is provided.

이 때, 상기 섬프(2) 내부에는 식기 세척 작용 완료 후 섬프(2)로 재유입된 세척수 내에 함유된 밥풀등의 오물을 여과시키는 필터(19)가 구비되고, 상기 섬프(2)에는 식기 세척 완료후 세척수를 외부로 배출하도록 배수유로(20)가 구비되며, 상기 배수유로(20)의 관로상에는 배수펌프(16)가 구비된다.At this time, the sump (2) is provided with a filter 19 for filtering dirt, such as rice grass contained in the wash water re-introduced into the sump (2) after completion of the dish washing action, the sump (2) A drainage passage 20 is provided to discharge the washing water to the outside after completion, and a drainage pump 16 is provided on the conduit of the drainage passage 20.

한편, 상기 배수유로(20)의 배수펌프(16) 후방에는 세척수의 역류를 방지하는 역류방지밸브(21)가 장착된다.On the other hand, the back of the drain pump 16 of the drain flow path 20 is equipped with a non-return valve 21 for preventing the back flow of the wash water.

이와 같이 구성된 식기세척기에서의 식기 세척 과정을 설명하면 다음과 같다.The dishwashing process of the dishwasher configured as described above is as follows.

식기세척기의 상부랙(17) 및 하부랙(18)에 세척할 식기를 장착한 상태에서 식기세척기의 동작시작 버튼을 눌러 식기세척기를 작동시키면, 먼저 급수유로(도시는 생략함)를 막고 있던 솔레노이드 밸브가 열려 세제와 세척수가 공급되는 급수 과정이 진행된다.If the dishwasher is operated by pressing the operation start button of the dishwasher with the dishes to be washed in the upper rack 17 and the lower rack 18 of the dishwasher, the solenoid blocking the water flow path (not shown) first. The valve is opened to supply water and detergent.

급수가 이루어진 후, 세척펌프(15)가 작동하면 급수된 세척수는 섬프(2)에 연결된 흡입구를 통하여 세척펌프(15)로 흡입되며, 상기 세척펌프(15)의 펌핑작용에 의해 상부 분사아암(3a) 및 하부 분사아암(3b)으로 압송된 세척수는 상기 상·하부 분사아암(3b)에 형성된 분사구를 통해 식기로 분사되어 식기에 부착된 오물에 대한 세척작용을 수행하게 된다.After the water supply is made, when the washing pump 15 is operated, the supplied washing water is sucked into the washing pump 15 through an inlet connected to the sump 2, and an upper injection arm (7) is pumped by the washing pump 15. The washing water pumped to the 3a) and the lower spray arm 3b is sprayed into the dish through the spray holes formed in the upper and lower spray arms 3b to perform the washing action on the dirt attached to the dish.

한편, 식기로 분사된 세척수는 세척 작용후 식기의 오물과 함께 터브(1)의 바닥으로 낙하하게 되고, 터브(1) 하부로 낙하한 세척수는 섬프(2)로 유입된 후 필터(19)를 거쳐 다시 세척펌프(15)로 재흡입되어 다시 펌핑된 후 상·하부분사아암(3a)(3b)을 통해 식기로 재분사된다.On the other hand, the washing water sprayed into the tableware drops to the bottom of the tub (1) with the dirt of the tableware after the washing action, the washing water dropped to the bottom of the tub (1) flows into the sump (2) and then the filter (19) After being sucked back into the washing pump 15 and pumped again, the powder is re-injected into the tableware through the upper and lower partial arms 3a and 3b.

상기한 바와 같은, 세척수의 펌핑 및 분사 과정의 반복에 의해 식기에 부착된 오물이 완전히 제거되면, 식기의 세척이 완료되며, 식기 세척이 끝나면 배수펌프(16)가 작동하여 필터(19)에 의해 걸러진 오물이 세척수와 함께 배수유로(20)를 통해 식기세척기 밖으로 배출된다.As described above, when the dirt attached to the tableware is completely removed by repetition of the pumping and spraying process of the washing water, the washing of the tableware is completed, and when the tableware is finished, the drain pump 16 operates by the filter 19. The filtered dirt is discharged out of the dishwasher through the drainage passage 20 together with the washing water.

한편, 상기 배수펌프(16)의 작동 정지시, 배수유로(20) 상에 설치된 역류방지밸브(21)는 배수유로를 닫아 배출된 오염수가 식기세척기 내부로 재유입되는 현상을 방지하게 된다.On the other hand, when the drainage pump 16 is stopped, the non-return valve 21 installed on the drainage passage 20 prevents the discharged polluted water from re-introducing into the dishwasher by closing the drainage passage.

이와 같은 식기세척기는 각 가정의 주방에 설치되는데, 식기세척기에 세척수를 공급하는 수도 배관 사정에 의해 녹 찌꺼기 등이 식기세척기로 유입되거나 수동 공급 불량으로 지하수를 이용하는 추세가 늘어남에 따라 지하수 이물질 즉, 모래 또는 이끼 등이 식기세척기로 유입되는 경우가 자주 발생하게 된다. 이와 같은 이물질 유입으로 식기세척기에 세척수를 공급하기 위한 급수밸브가 고장나고 결국 급수불량을 초래하게 된다.Such dishwashers are installed in the kitchen of each home, and groundwater debris, that is, rust residues are introduced into the dishwasher due to the water supply pipe supplying the washing water to the dishwasher, or the groundwater is used due to manual supply failure. Sand or moss often enters the dishwasher. The inflow of foreign matters causes a breakdown of the water supply valve for supplying the washing water to the dishwasher, resulting in water supply failure.

그러나 상술한 급수불량으로 인한 과급수로 주방 및 가정내로 물이 넘쳐도 종래의 식기세척기에는 이를 감지 또는 처리하기 위한 수단이 구비되어 있지 못하므로 사용자의 불만을 초래하는 문제점이 있다.However, even if the water overflows into the kitchen and the home due to the above-mentioned water supply failure, the conventional dishwasher does not have a means for detecting or processing the same, which causes a problem for the user.

따라서 본 발명은 상기한 종래의 문제점을 해결하기 위하여 안출한 것으로서, 과급수를 자동으로 감지하고 배수를 수행하여 물 넘침 등의 사용자 불편을 방지할 수 있도록 한 식기세척기의 과급수 제어방법을 제공함에 그 목적이 있다.Therefore, the present invention has been made to solve the above-mentioned problems, to provide a supercharged water control method of the dishwasher to automatically detect the supercharged water and perform drainage to prevent user inconvenience, such as water overflow.
