Description

드럼세탁기{DRUM TYPE WASHING MACHINE}Drum Washing Machine {DRUM TYPE WASHING MACHINE}

본 발명은 드럼세탁기에 관한 것이다.The present invention relates to a drum washing machine.

일반적으로 드럼세탁기는, 회전하는 드럼과 세탁물의 상호 마찰 및 세탁물이 회전하는 드럼에서 윗쪽에서 아래쪽으로 떨어질 때의 두드림을 이용하여 세탁을 하는 장치로, 세탁물의 손상이 거의 없고, 세탁물이 서로 엉키지 않는 장점을 가지고 있다.In general, a drum washing machine is a device for washing by using a friction between the rotating drum and the laundry and tapping when the laundry falls from the top to the bottom of the rotating drum, and there is little damage to the laundry, and the laundry does not get tangled with each other. It has advantages

이러한 드럼세탁기는, 일반적으로 외관을 형성하는 캐비넷과, 캐비넷 내부에 설치된 터브와, 터브내 회전가능하게 설치된 드럼과, 캐비넷과 터브 사이에 개재되어 세탁수가 새워나가지 않게 막는 가스켓을 구비한다.Such a drum washing machine generally includes a cabinet forming an exterior, a tub installed inside the cabinet, a drum rotatably installed in the tub, and a gasket interposed between the cabinet and the tub to prevent washing water from leaking out.

한편, 이러한 가스켓은 구조상 캐비넷과 터브 사이에 일측이 접혀진 상태로 개재되어 있다. 이렇게 접혀진 부분에 오염물(세제찌꺼기나 린트(lint)등)이 끼이게 되고, 운전이 끝난 후에도 오염물은 제거되지 않고 그대로 남아있게 된다.On the other hand, such a gasket is interposed in a state in which one side is folded between the cabinet and the tub. Contaminants (detergents, lints, etc.) are caught in the folded parts, and after the operation is completed, the contaminants are not removed but remain intact.

이렇게 남아 있는 오염물이 부패하여 냄새가 발생한다. 또한, 드럼세탁기의 습한 내부환경에서 오염물로부터 영양분을 공급받은 곰팡이가 서식하게 되고, 이렇게 서식하는 곰팡이로 인해 냄새가 발생하는 문제점이 있었다.The remaining contaminants decay and produce an odor. In addition, a mold supplied with nutrients from contaminants in a humid internal environment of the drum washing machine is inhabited, and there is a problem in that smell occurs due to the mold.

본 발명은 상술한 문제점을 해결하기 위하여 창안된 것으로, 냄새가 제거된 드럼세탁기를 제공하는 데 목적이 있다. 또한, 가스켓에 남아있는 오염물을 제거하는 드럼세탁기를 제공하는 데 다른 목적이 있다.The present invention has been made to solve the above problems, and an object of the present invention is to provide a drum washing machine from which the smell is removed. Another object is to provide a drum washing machine for removing contaminants remaining in the gasket.

도 2 및 도 3을 참조하면, 상기 냄새제거유닛(80)은, 순환호스(52)에서 분지되어 가스켓(2)의 하면의 개구(2aa)에 연결된 냄새제거호스(81)와, 냄새제거호스(81)에 설치된 개폐밸브(82)를 포함한다.2 and 3, the odor removing unit 80 is branched from the circulation hose 52, the odor removing hose 81 connected to the opening 2aa of the lower surface of the gasket 2, odor removing hose And an on-off valve 82 provided at 81.

상기 개구(2aa)에는 이물질이 순환호스(52)로 빨려들어가 순환호스(52)를 막는 것을 방지하기 위한 거름망(84)이 설치된다.The opening 2aa is provided with a strainer 84 for preventing foreign matter from being sucked into the circulation hose 52 and blocking the circulation hose 52.

상기 냄새제거호스(81)는, 순환호스(52)와 Y 커넥터(83)로 연결되어 있으므로, 순환호스(52)를 타고 터브(3)로 공급되는 순환되는 세탁수의 일부가 냄새제거호스(81)로 공급된다. 공급된 세탁수는 냄새제거호스(81)를 따라 개구(2aa)에서 분사되어 가스켓(2)의 접혀진 부분(2a)에 남아있는 오염물(P)을 제거하게 된다.Since the odor removal hose 81 is connected to the circulation hose 52 and the Y connector 83, a part of the circulating wash water supplied to the tub 3 by the circulation hose 52 is an odor removal hose ( 81). The supplied washing water is sprayed from the opening 2aa along the odor removing hose 81 to remove the contaminants P remaining in the folded portion 2a of the gasket 2.

상기 개폐밸브(82)는 솔레노이드 밸브로 구성되며, 헹굼 운전중에 열리게 된다. 따라서, 헹굼 운전중에 순환펌프(51, 도 1참조)가 작동하여 세탁수를 터브(3) 로 공급할 때, 공급되는 세탁수의 일부가 냄새제거호스(81)로 공급될 수 있다. 따라서, 세탁물이 헹구어지는 동안, 가스켓(2)의 접혀진 부분(2a)에 남아있는 오염물도 함께 제거된다.The on-off valve 82 is composed of a solenoid valve, it is opened during the rinsing operation. Therefore, when the circulating pump 51 (see FIG. 1) operates during the rinsing operation to supply the washing water to the tub 3, a part of the washing water supplied may be supplied to the odor removing hose 81. Thus, while the laundry is rinsed, the contaminants remaining in the folded portion 2a of the gasket 2 are also removed together.

도 4a,도 4b 및 도 4c는 도 3의 개구를 통해 분사되는 세탁수에 의해 오염물이 제거되는 과정을 나타낸 도면이다. 도 4a 내지 도 4c를 참조하면, 냄새제거호스(81)를 따라 개구(2aa)에서 분사된 세탁수에 의해, 가스켓(2)의 접혀진 부분(2a)에 남아있는 오염물(P)이 서서히 제거되어 결국 모두 제거되게 된다.4A, 4B, and 4C are views illustrating a process of removing contaminants by washing water sprayed through the opening of FIG. 3. 4A to 4C, contaminants P remaining in the folded portion 2a of the gasket 2 are gradually removed by the washing water sprayed from the opening 2aa along the odor removing hose 81. Eventually all will be removed.

이로 인해, 오염물이 부패하여 냄새가 발생하는 것을 방지할 수 있다. 또한, 드럼세탁기의 습한 내부환경에서 오염물로부터 영양분을 공급받은 곰팡이가 서식하는 것이 방지되어, 서식하는 곰팡이로 인해 냄새가 발생하는 문제점을 해결할 수 있다.For this reason, it is possible to prevent the pollutants from decaying and generating odors. In addition, in the humid internal environment of the drum washing machine is prevented from the mold supplied with nutrients from the contaminants, it is possible to solve the problem that the odor occurs due to the mold.

도 5는 도 1의 냄새제거유닛의 변형예를 나타낸 도면이고, 도 6은 도 5의 냄새제거유닛의 요부를 발췌하여 나타낸 사시도이다.5 is a view showing a modification of the odor removing unit of Figure 1, Figure 6 is a perspective view showing the main portion of the odor removing unit of FIG.

도 5 및 도 6을 참조하면, 상기 냄새제거유닛(80)은, 가스켓(2)의 하면의 개구(2aa)에 설치된 분사노즐(85)과, 순환호스(52)에서 분지되어 분사노즐(85)과 연결된 냄새제거호스(81)와, 냄새제거호스(81)에 설치된 개폐밸브(82)를 포함한다.5 and 6, the odor removing unit 80 is branched from an injection nozzle 85 provided in an opening 2aa of the lower surface of the gasket 2 and a circulation hose 52 to eject the injection nozzle 85. ) And an odor removal hose 81 and an open / close valve 82 installed in the odor removal hose 81.

상기 분사노즐(85)은 냄새제거호스(81)로부터 공급받은 세탁수를 분사공(85a)를 통해 일정각도(θ)로 분사한다. 본 실시예에서는 약 120°의 각도로 분사한다. 이렇게 세탁수를 일정각도로 분사하므로, 가스켓(2)의 하면의 넓은 면적에 세탁수가 뿌려지므로, 넓은 면적에 분산되어 있는 오염물을 보다 효과적으로 제거 할 수 있다. 또한, 분사공(85a)을 통해 세탁수가 분사되므로, 분사력에 의해 보다 강력하게 오염물을 제거할 수 있다.The injection nozzle 85 sprays the washing water supplied from the odor removing hose 81 at a predetermined angle θ through the injection hole 85a. In this embodiment, the jet is performed at an angle of about 120 °. Since the washing water is sprayed at a predetermined angle, the washing water is sprayed on the large area of the lower surface of the gasket 2, so that contaminants dispersed in the large area can be more effectively removed. In addition, since the washing water is injected through the injection hole 85a, the contaminants may be more strongly removed by the injection force.

상기 냄새제거호스(81)는, 순환호스(52)와 Y 커넥터(83)로 연결되어 있으므로, 순환호스(52)를 타고 터브(3)로 공급되는 순환되는 세탁수의 일부가 냄새제거호스(81)로 공급된다. 공급된 세탁수는 냄새제거호스(81)를 따라 분사노즐(85)의 분사공(85a)을 통해 분사되어 가스켓(2)의 접혀진 부분(2a)에 남아있는 오염물(P)을 제거하게 된다.Since the odor removal hose 81 is connected to the circulation hose 52 and the Y connector 83, a part of the circulating wash water supplied to the tub 3 by the circulation hose 52 is an odor removal hose ( 81). The supplied wash water is sprayed through the injection hole 85a of the injection nozzle 85 along the odor removal hose 81 to remove contaminants P remaining in the folded portion 2a of the gasket 2.

상기 개폐밸브(82)는 솔레노이드 밸브로 구성되며, 헹굼 운전중에 열리게 된다. 따라서, 헹굼 운전중에 순환펌프(51, 도 1참조)가 작동하여 세탁수를 터브(3)로 공급할 때, 공급되는 세탁수의 일부가 냄새제거호스(81)로 공급될 수 있다. 따라서, 세탁물이 헹구어지는 동안, 가스켓(2)의 접혀진 부분(2a)에 남아있는 오염물도 함께 제거되게 된다.The on-off valve 82 is composed of a solenoid valve, it is opened during the rinsing operation. Therefore, when the circulating pump 51 (see FIG. 1) is operated to supply the washing water to the tub 3 during the rinsing operation, a part of the washing water supplied may be supplied to the odor removing hose 81. Thus, while the laundry is rinsed, the contaminants remaining in the folded portion 2a of the gasket 2 are also removed together.

이렇게 오염물이 제거됨으로 인해, 드럼세탁기의 습한 내부환경에서 오염물로부터 영양분을 공급받은 곰팡이가 서식하는 것이 방지되어, 서식하는 곰팡이로 인해 냄새가 발생하는 문제점을 해결할 수 있다.By removing the contaminants in this way, molds supplied with nutrients from the contaminants in the humid internal environment of the drum washing machine are prevented from being inhabited, thereby solving the problem of odors caused by the inhabiting molds.
