Contains 53

이하에서는 상기 실시예에 따른 드럼세탁기(100)의 수위감지장치(50)를 구비하는 드럼세탁기(100)의 동작을 설명한다. Hereinafter, the operation of the drum washing machine 100 having the water level detecting device 50 of the drum washing machine 100 according to the embodiment will be described.

옷감 등의 세탁물은 구동모터(22)에 의해 회전하는 회전조(21)에 놓여 세탁된다. 회전조(21)가 회전할 때 상기 회전조(21) 측면에 장착된 리프터(25)가 세탁물을 상기 회전조(21) 상부로 끌어올렸다가 떨어뜨리면서 이 때 발생하는 충격력과 세탁물 간의 마찰력 등에 의해 세탁이 이루어진다. Laundry such as cloth is placed in a rotating tub 21 which is rotated by the drive motor 22 and washed. When the rotating tub 21 rotates, the lifter 25 mounted on the side of the rotary tub 21 pulls the laundry up and down the rotary tub 21, and the friction force between the laundry and the laundry is generated. Washing is done.

세탁에 필요한 물은 급수관(30)을 통해서 공급되며, 이 급수관(30)은 세제통(33)에 연결되어 있어서, 세탁에 필요한 세제를 물과 함께 용해하여 공급한다. 물을 공급할 때 적정량의 물을 공급하기 위하여 상기 수위감지장치(50)로 상기 회전조(21) 내의 수위를 측정하게 된다. The water required for washing is supplied through the water supply pipe 30, and the water supply pipe 30 is connected to the detergent container 33, and supplies the detergent required for washing with water. When water is supplied, the water level in the rotating tank 21 is measured by the water level detecting device 50 to supply an appropriate amount of water.

상기 수위감지장치(50)의 수위감지호스(51) 하단의 확관부(53)는 상기 배수펌프(40)의 흡입관(41)과 상기 제1배수관(31)을 통하여 상기 고정조(20)의 하부와 연통되어 있어, 상기 고정조(20)에 물이 채워짐에 따라 상기 확관부(53)의 수위도 함께 올라간다. 이 확관부(53)의 수위가 차츰 올라감에 따라 수위감지호스(51) 내의 공기가 압축되어 압력이 증가하게 되고, 이 압력 변화가 수위감지센서(54)에 의해 감지되어 상기 고정조(20)의 수위를 측정하게 된다. The expansion pipe 53 at the lower end of the water level detection hose 51 of the water level detection device 50 is connected to the suction tank 41 and the first drain pipe 31 of the drainage pump 40. It is in communication with the lower portion, the water level of the expansion pipe 53 also rises as the fixing tank 20 is filled with water. As the water level of the expansion pipe 53 gradually rises, the air in the water level detecting hose 51 is compressed to increase the pressure, and this change in pressure is detected by the water level sensor 54 so that the fixed tank 20 The water level will be measured.

한편 상기 수위감지호스(51)의 하단부는 종래에 고정조(20) 측에 연결되어 있던 것과는 달리 케이스(10)에 고정되어 있는 상기 배수펌프(40)의 흡입관(41) 측에 연결되어 있기 때문에, 구동모터(22)에 의한 진동의 영향을 받지 않게 된다. On the other hand, the lower end of the water level detection hose 51 is connected to the suction pipe 41 side of the drain pump 40 fixed to the case 10, unlike the conventional connection to the fixed tank 20 side The vibration of the driving motor 22 is not affected.

그리고 상기 수위감지호스(51)는 그 하부에 직경이 큰 확관부(53)를 갖기 때문에, 직경이 균일한 경우에 비하여 동일한 수위변화에 따른 압력변화량이 크고 따라서 정확한 수위 감지가 가능하다.In addition, since the water level detecting hose 51 has a large diameter expansion portion 53 at the lower portion thereof, the amount of pressure change due to the same water level change is larger than the case where the diameter is uniform, thus enabling accurate water level detection.

상기 확관부(53)의 수면에는 압축된 공기의 압력이 작용하고 있어 대기압이 작용하고 있는 고정조(20)의 수면에 비하여 낮게 유지되는데, 고정조(20) 내의 수위가 최대일 때에도 이 확관부(53) 내의 수위가 협관부(52)까지 도달하지 않도록 이 확관부(53)의 길이를 충분히 길게 하면, 상기 협관부(52)에 보푸라기 등의 이물질이 막혀서 수위감지장치(50)가 오작동을 일으키는 것을 방지할 수 있다. 이를 위하여 확관부(53)의 길이는 10cm 이상인 것이 바람직하다. The pressure of the compressed air is acting on the water surface of the expansion pipe 53 and is kept lower than the water surface of the fixed water tank 20 in which atmospheric pressure is applied, even when the water level in the fixed water tank 20 is maximum. If the length of the expansion pipe 53 is sufficiently long so that the water level in the 53 does not reach the narrowing pipe part 52, foreign matters such as lint and the like will be blocked in the buccal pipe part 52, causing the water level detecting device 50 to malfunction. Can be prevented. For this purpose, the length of the expansion tube 53 is preferably 10 cm or more.

이상에서 상세히 설명한 바와 같이, 본 발명에 따른 드럼세탁기의 수위감지장치는 수위감지호스가 케이스 측에 고정된 배수펌프 측에 연결되어 있기 때문에 진동에 의한 마모와 파손이 방지되며, 상기 수위감지호스는 상부에 비하여 직경이 큰 확관부를 구비하고 있어서 정확한 수위측정이 가능하고 보푸라기 등의 이물질의 막혀서 수위감지장치가 오작동을 일으키는 것이 방지되는 효과가 있다. As described above in detail, the water level sensing device of the drum washing machine according to the present invention is prevented from abrasion and damage due to vibration because the water level sensing hose is connected to the drain pump side fixed to the case side, the water level sensing hose Compared with the upper part, the expansion part having a larger diameter enables accurate water level measurement and prevents the water level detecting device from malfunctioning due to clogging of foreign matter such as lint.
