상기한 과제를 해결하기 위한 본 발명에 따른 드럼 세탁기의 거품 유출 방지 구조는 세제통의 배출구와 터브의 급수구에 연결된 인렛 벨로우즈와; 상기 급수구에 설치되어 터브 내의 거품이 차오르는 것을 막는 플로우트 밸브로 구성된 것을 특징으로 한다.Bubble outflow prevention structure of the drum washing machine according to the present invention for solving the above problems is an inlet bellows connected to the outlet of the detergent container and the water supply port of the tub; It is characterized by consisting of a float valve installed in the water inlet to prevent the bubbles in the tub from filling up.

이하, 본 발명의 실시 예를 첨부된 도면을 참조하여 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명에 따른 드럼 세탁기의 일실시예가 도시된 사시도이다.1 is a perspective view showing an embodiment of a drum washing machine according to the present invention.

본 발명 일실시예의 드럼 세탁기는 도 1에 도시된 바와 같이, 케이스(2)의 전면에 도어(4)가 여닫힘 가능하게 설치되고, 케이스(2) 내부에 지지된 터브(미도시) 내부에 세탁물이 수용되는 드럼(6)이 설치되며, 상기 케이스(2) 내부에 설치된 구동모터(미도시)의 구동시 상기 드럼(6)이 회전되면서 세탁물의 세탁, 헹굼, 탈수가 행해진다.As shown in FIG. 1, the drum washing machine according to an embodiment of the present invention has a door 4 installed on the front of the case 2 so as to be openable and closed, and inside a tub (not shown) supported inside the case 2. A drum 6 for receiving laundry is installed, and the drum 6 is rotated when the driving motor (not shown) installed in the case 2 is rotated to wash, rinse and dehydrate the laundry.

상기 케이스(2)의 상부에는 세탁물의 세정에 필요한 세제 또는 유연제가 저장됨과 아울러 세탁에 필요한 물의 급수통로가 형성된 세제통(10)이 배치되고, 상기 세제통(10)과 상기 터브의 사이에는 인렛 벨로우즈(미도시)가 연결되어 세제와 물을 터브 내로 공급한다.The upper part of the case (2) stores a detergent or a softener for washing the laundry, and a detergent container (10) formed with a water supply passage for washing water is disposed, and the inlet bellows (between the detergent container 10 and the tub) (Not shown) to supply detergent and water into the tub.

도 2는 본 발명에 따른 드럼 세탁기의 물/세제 공급부가 도시된 단면도이다.2 is a sectional view showing a water / detergent supply unit of the drum washing machine according to the present invention.

상기 인렛 벨로우즈(20)는 도 2에 도시된 바와 같이, 일단이 상기 세제통의 배출구(미도시)와 연결되고, 타단이 상기 터브(30)의 급수구(32)에 연결된다.As shown in Figure 2, the inlet bellows 20, one end is connected to the outlet (not shown) of the detergent container, the other end is connected to the water supply port 32 of the tub (30).

그리고, 상기 터브(30)의 급수구(32)에는 플로우트 밸브(40)가 설치되어 상기 터브(30) 내에 생성된 거품이 인렛 벨로우즈(20)를 통해 세제통으로 유출되는 것을 막는다.In addition, a float valve 40 is installed at the water supply port 32 of the tub 30 to prevent bubbles generated in the tub 30 from flowing into the detergent container through the inlet bellows 20.

여기서, 상기 플로우트 밸브(40)는 상기 터브(20)에서 차오르는 거품에 의해 상승되고, 일정 높이 만큼 상승되었을 때 상단이 상기 인렛 벨로우즈(20)의주름부(22)에 걸림되어 상향 이동이 규제되면서 상기 인렛 벨로우즈(20)의 내부를 막는다.Here, the float valve 40 is raised by the bubbles rising from the tub 20, when the upper end is caught by the pleats 22 of the inlet bellows 20 when the height is raised by a certain height is regulated upward movement The inside of the inlet bellows 20 is blocked.

그리고, 상기 터브(30)의 급수구(32)는 내둘레면에 리브(34)가 복수개 형성되어 상기 플로우트 밸브(40)가 급수구(32)의 내둘레면과 틈을 갖고 상하 이동되도록 안내한다.In addition, a plurality of ribs 34 are formed on the inner circumferential surface of the water inlet 32 of the tub 30 so that the float valve 40 moves up and down with a gap with the inner circumferential surface of the water inlet 32. do.

도 3은 본 발명에 따른 터브의 급수구가 도시된 평면도이다.3 is a plan view showing a water supply port of the tub according to the present invention.

상기 리브(34)는 상기 플로우트 밸브의 하단이 걸림되는 단턱(36)이 급수구(32)의 중앙을 향해 돌출 형성되어 상기 플로우트 밸브(40)의 하향 이탈을 막는다.The rib 34 has a step 36 formed to engage the lower end of the float valve so as to protrude toward the center of the water inlet 32 to prevent the downward departure of the float valve 40.

상기와 같이 구성된 본 발명의 동작을 살펴보면 다음과 같다.Looking at the operation of the present invention configured as described above are as follows.

먼저, 세탁물이 드럼(6)에 투입되고, 상기 세제통(10)에서 혼합된 세제와 물은 상기 인렛 벨로우즈(20)를 통해 터브(30)의 급수구(32)로 공급된다. 상기 급수구(32)로 공급된 세제와 물은 상기 플로우트 밸브(40)와 급수구(32)의 내둘레면 사이의 틈을 통해 터브(30)의 내부로 공급되고, 상기 드럼(6)이 회전되면 상기 터브(30)의 내부에서는 거품이 생성된다.First, the laundry is put into the drum 6, the detergent and water mixed in the detergent container 10 is supplied to the water supply port 32 of the tub 30 through the inlet bellows (20). Detergent and water supplied to the water inlet 32 is supplied into the tub 30 through a gap between the float valve 40 and the inner circumferential surface of the water inlet 32, and the drum 6 is When rotated, bubbles are generated inside the tub 30.

이러한 거품은 상기 터브(30)의 급수구(32)까지 차올라 상기 리브(34)의 단턱(36)에 올려져 있던 상기 플로우트 밸브(40)를 상승시킨다.This foam rises up to the water inlet 32 of the tub 30 and raises the float valve 40 which has been raised on the step 36 of the rib 34.

상기 플로우트 밸브(40)는 일정 높이만큼 상승된 후 상기 인렛 벨로우즈(20)의 주름부(22)에 걸림되어 상기 인렛 벨로우즈(20)의 내부를 막고 터브(20) 내의 거품이 인렛 벨로우즈(20)와 세제통(10)으로 유출되지 않도록 한다.After the float valve 40 is raised by a predetermined height, the float valve 40 is caught by the pleats 22 of the inlet bellows 20 to block the inside of the inlet bellows 20 and bubbles in the tub 20 are inlet bellows 20. Do not spill into the detergent container (10).

그런 다음, 상기 터브(20) 내에서 거품이 제거되면 상기 플로우트 밸브(40)는 자중에 의해 하향 이동되어 상기 리브(34)의 단턱(36)에 올림된다.Then, when bubbles are removed in the tub 20, the float valve 40 is moved downward by its own weight and raised to the step 36 of the rib 34.

상기와 같이 구성되는 본 발명에 따른 세탁기의 거품 유출 방지 구조는 인렛 벨로우즈가 연결된 터브의 급수구에 플로우트 밸브가 배치되고, 터브 내에 거품이 차오를 때 플로우트 밸브가 인렛 벨로우즈의 주름부에 걸림되어 인렛 벨로우즈 내부를 막으므로, 터브 내의 거품이 인렛 벨로우즈를 통해 세제통으로 유출되는 것을 막을 수 있는 이점이 있다.The foam leakage prevention structure of the washing machine according to the present invention is configured as described above, the float valve is disposed in the water supply port of the tub connected to the inlet bellows, when the bubble fills in the tub, the float valve is caught in the pleats of the inlet bellows inlet By blocking the inside of the bellows, there is an advantage that can prevent the foam in the tub from flowing into the detergent container through the inlet bellows.
