Description

세탁기의 누수 감지장치 및 그 제어방법 { The apparatus of the leak sensor of washer and the same method }Leak detection device and control method of the washing machine {The apparatus of the leak sensor of washer and the same method}

본 발명은 세탁기의 누수 감지장치 및 그 제어방법에 관한 것으로서, 특히 세탁조에서 세탁수가 누수되면 이를 감지하여 세탁기의 작동을 중단시키는 세탁기의 누수 감지장치 및 그 제어방법에 관한 것이다.The present invention relates to a leak detection device for a washing machine and a control method thereof, and more particularly, to a leak detection device for a washing machine and a control method for stopping the operation of the washing machine by detecting the wash water leak in the washing tank.

종래 기술에 따른 드럼 세탁기는 도 1에 도시된 바와 같이, 외관을 형성하는 캐비닛(1) 내측에 원통형의 세탁조(2)가 설치되고, 상기 세탁조(2)의 내측에는 드럼(3)이 회전가능하게 설치된다.In the drum washing machine according to the related art, as shown in FIG. 1, a cylindrical washing tub 2 is installed inside a cabinet 1 forming an exterior, and a drum 3 is rotatable inside the washing tub 2. Is installed.

그리고, 상기 드럼(3)의 후방에는 스파이더(3a)가 고정되어 구동축(3b)의 전단부가 축연결되고, 상기 구동축(3b)은 세탁조(2)의 중앙부를 관통하여 모터부(10)의 회전자(11)에 연결된다.Then, the spider 3a is fixed to the rear of the drum 3 so that the front end of the drive shaft 3b is axially connected, and the drive shaft 3b penetrates the central portion of the washing tank 2 to rotate the motor unit 10. Is connected to the electron 11.

한편, 상기 캐비닛(1)의 배면 상단측에는 급수호스(5)가 급수밸브(4)를 통해 상기 세탁조(2) 내로 연결되고, 상기 캐비닛(1)의 상부면 내측과 세탁조(2)의 외주면 상부측 사이에는 상기 세탁조(2)를 지지하는 스프링(9)이 설치되며, 상기 캐비닛(1) 하부면 내측과 상기 세탁조(2)의 외주면 하부측 사이에는 세탁기의 가동 시 발생하는 상기 세탁조(2)의 진동을 감쇠시키기 위한 댐퍼(8)가 설치된다.On the other hand, a water supply hose 5 is connected to the washing tank 2 through the water supply valve 4 at the upper end side of the rear surface of the cabinet 1, and inside the upper surface of the cabinet 1 and the upper outer peripheral surface of the washing tank 2. A spring 9 for supporting the washing tub 2 is installed between the sides, and the washing tub 2 generated when the washing machine is operated between the inside of the lower surface of the cabinet 1 and the lower side of the outer circumferential surface of the washing tub 2. A damper 8 is provided to damp the vibration of the.

상기와 같이 구성된 종래의 드럼세탁기는 다음과 같이 작동한다.The conventional drum washing machine configured as described above operates as follows.

상기 급수밸브(4)의 개방으로 세탁수가 상기 급수호스(5)를 통해 상기 세탁조(2)를 거쳐 상기 드럼(3) 내에 세탁수가 채워진 다음, 모터부(10)의 고정자(12)에 전원이 인가되면 회전자(11)가 회전하게 된다. 상기 회전자(11)의 회전에 의해 구동축(3b)이 회전하게 되고, 상기 구동축(3b)이 회전함에 의해 드럼(3)을 회전시키게 된다.The washing water is filled in the drum 3 through the washing tank 2 through the water supply hose 5 by opening the water supply valve 4, and then power is supplied to the stator 12 of the motor unit 10. When applied, the rotor 11 rotates. The drive shaft 3b is rotated by the rotation of the rotor 11, and the drum 3 is rotated by the rotation of the drive shaft 3b.

그리하여, 상기 드럼(3)의 내부에 수용된 세탁물이 세탁수 및 드럼(3)과의 마찰력에 의해 세탁이 이루어지게 된다.Thus, the laundry contained in the drum 3 is washed by the washing water and the friction force with the drum 3.

그러나, 종래의 세탁기는 상기 급수호스(5)를 통해 상기 세탁조(2)로 세탁수가 유입되는 동안, 상기 세탁조(2)에서 누수가 발생되는 경우에 이를 인지하여 상기 급수밸브(4)를 차단하기 위한 수단이 구비되어 있지 않으므로 계속해서 상기 세탁조(2)로 부터 누수가 발생되어 상기 캐비닛(1) 내측에 장착되는 각종 부품을 부식시킴과 아울러 세탁기가 설치된 바닥면을 오염시키는 문제점이 있다.However, the conventional washing machine recognizes this when the water leak occurs in the washing tank 2 while the washing water flows into the washing tank 2 through the water supply hose 5 to block the water supply valve 4. Since there is no means for it, there is a problem in that water is continuously generated from the washing tank 2 to corrode various parts mounted inside the cabinet 1 and to contaminate the bottom surface of the washing machine.

본 발명은 상기한 종래 기술의 문제점을 해결하기 위하여 안출된 것으로서, 세탁조에서 누수가 발생되는 경우에, 이를 감지하여 세탁수가 더 이상 누수되는 것을 차단하여 세탁기의 각종 부품이 부식되는 것을 방지하고 세탁기가 설치된 바닥면의 오염을 방지하는데 그 목적이 있다.The present invention has been made in order to solve the above problems of the prior art, when a leak occurs in the washing tank, by detecting this to prevent the wash water from leaking any more to prevent the corrosion of various parts of the washing machine and The purpose is to prevent contamination of the installed floor.

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, 제 1단계는 세탁수행을 위해 세탁기의 배면 상단에 형성된 급수밸브(미도시)가 열리면서 급수호스(미도시)를 따라 세탁수가 세탁조(미도시) 내로 유입되는 과정에서 세탁조에 누수가 발생되면, 누수된 세탁수가 세탁기의 하부패널(22)에 형성된 고임목(25)에 유입되어 고이게 된다.(S1,S2,S3 참조)First, in the first step, when a water supply valve (not shown) is formed at the top of the back of the washing machine to perform washing, water leaks in the washing tank while the washing water flows into the washing tank (not shown) along the water supply hose (not shown). The leaked washing water flows into the stump wood 25 formed in the lower panel 22 of the washing machine. (See S1, S2, and S3)

제 2단계는 상기 고임목(25) 내에 구비된 부력부재(31)가 누수된 세탁수로인해 상승하게 된다.(S4 참조)In the second step, the buoyancy member 31 provided in the stump 25 is raised due to the leaked wash water. (See S4.)

제 3단계는 상기 고임목(25)에 유입되는 세탁수가 계속 증가하여 상기 부력부재(31)가 택트 스위치(32)와 접촉되는 경우와, 상기 고임목(25)에 유입된 세탁수의 양이 적어 상기 부력부재(31)가 상기 택트 스위치(32)와 접촉하지 못하는 경우에 따라 세탁수의 누수 여부가 결정된다.(S5 참조)The third step is a case where the washing water flowing into the tree wood 25 continues to increase and the buoyancy member 31 is in contact with the tact switch 32, and the amount of the washing water flowing into the tree wood 25 is small. Whether the buoyancy member 31 does not come into contact with the tact switch 32 determines whether the wash water leaks. (See S5.)

이 때, 상기 고임목(25)에 유입된 세탁수의 양이 적어 상기 부력부재(31)가 충분히 상승하지 못하여 상기 택트 스위치(32)와 접촉하지 못하면 세탁수의 누수가 일어나지 않았다고 판단하여 세탁수의 급수완료 시까지 급수행정이 진행된다.At this time, if the amount of wash water introduced into the stubble 25 is small, the buoyancy member 31 is not sufficiently raised and does not come into contact with the tact switch 32 determines that no leak of wash water has occurred. The water supply stroke is carried out until the completion of water supply.

한편, 상기 고임목(25)으로 세탁수가 지속적으로 유입되어 상기 부력부재(31)에 의한 택트 스위치(32)와의 접촉이 일어나면 세탁조(미도시)에 누수가 발생된 것으로 판단한다.(S6 참조)On the other hand, when the wash water is continuously introduced into the solid wood 25 and the contact with the tact switch 32 by the buoyancy member 31 occurs, it is determined that a leak occurs in the washing tank (not shown) (see S6).

제 4단계는 상기 3단계에서 누수가 발생된 것으로 판단된 경우, 상기 택트 스위치(32)에서 발생된 전기적 신호가 리드 와이어(34)를 통해 마이컴(40)으로 전달되고 제어부(50)의 통제로써 급수밸브(미도시)가 차단되어 급수가 중단되며 외부에 구비된 경고수단(60)을 통해 누수사실이 표시되게 된다.(S7,S8 참조)In the fourth step, when it is determined that the leakage occurs in the third step, the electrical signal generated by the tact switch 32 is transmitted to the microcomputer 40 through the lead wire 34 and under the control of the controller 50. The water supply valve (not shown) is cut off so that the water supply is stopped and the leaking fact is displayed through the warning means 60 provided on the outside.

상기와 같이 구성되는 본 발명에 따른 세탁기의 누수 감지장치 및 그 제어방법은 세탁조로부터 누수가 발생될 경우, 세탁조의 하부에 설치된 세탁수 저장수단에 누수된 세탁수가 고이도록 하고 이를 누수 감지수단으로써 감지하여 급수밸브를차단하고 세탁조 내로 세탁수가 급수되는 것을 중단시킴으로써 누수를 막아 세탁기 내에 설치된 부품이 부식되는 것을 방지하고 세탁기가 설치된 바닥면이 세탁수에 의하여 오염되지 않도록 하는 효과가 있다.Leakage detection device and control method of the washing machine according to the present invention configured as described above, when the leak occurs from the washing tank, the wash water leaked in the washing water storage means installed in the lower portion of the washing tank is accumulated and detected as the leak detection means By blocking the water supply valve and stopping the water supply to the washing tank, the water leakage is prevented, thereby preventing corrosion of the components installed in the washing machine and preventing the floor on which the washing machine is installed from being contaminated by the washing water.
