상기 제어부(12)는 모터(7)나 초음파 발생장치(6)의 작동상태를 사용자가 인지할 수 있도록 하기 위해 디스플레이부(15)를 포함한다.The control unit 12 includes a display unit 15 to allow a user to recognize an operating state of the motor 7 or the ultrasonic wave generator 6.

상기와 같이 구성된 본 발명에 의한 세탁기에서 세정작업이 수행되는 과정과 이때 발생되는 작용을 상세히 설명하면 다음과 같다.When the washing operation is performed in the washing machine according to the present invention configured as described above and the action generated at this time will be described in detail.

도 1을 참조하면, 본 발명에 의한 세탁기의 세정작업은 세탁외조(2) 및 세탁내조(3)에 적정한 수위로 물을 급수하고 세탁내조(3)와 세탁날개(4)를 회전시키며 초음파 발생장치(6)를 작동시키면, 초음파 발생장치(6)에서 발생된 초음파에 의해 세탁외조(2)의 내측면 및 세탁내조(3)의 내, 외측면에 잔류하는 오염물질이 분해되어 탈리되고, 이러한 상태에서 급수된 물을 세탁기의 외부로 배수시켜 작업이 수행된다.Referring to Figure 1, the washing operation of the washing machine according to the present invention supplies water to the washing water tank 2 and the washing tank 3 at an appropriate level, and rotates the washing tank 3 and the washing blade 4 to generate ultrasonic waves. When the device 6 is operated, contaminants remaining on the inner surface of the washing outer tank 2 and the inner and outer surfaces of the washing inner tank 3 are decomposed and detached by ultrasonic waves generated by the ultrasonic generator 6, In this state, the water is drained out of the washing machine to perform the work.

여기서, 상기 초음파에 의해 오염물질이 분해되고 탈리되는 작용을 설명한다.Here, the operation of decomposing and detaching the contaminants by the ultrasonic wave will be described.

상기 세탁내조(3)와 세탁날개(4)가 회전됨에 의해 발생된 수류측으로 초음파가 방사되면 수류의 내측에는 캐비테이션(Cavitation)현상에 의해 고압(高壓)의 캐비티(Cavity)가 발생되고, 발생된 캐비티가 상기 수류에 의해 세탁외조(2)와 세탁내조(3)의 사이공간으로 이동된다.When ultrasonic waves are radiated to the side of the water generated by rotating the washing tub 3 and the washing blade 4, a cavity of high pressure is generated inside the water stream by a cavitation phenomenon. The cavity is moved to the space between the washing tub 2 and the washing tub 3 by the flow of water.

상기와 같이 이동되던 캐비티가 세탁외조(2) 또는 세탁내조(3)의 벽면 또는 오염물질과 접촉되어 터지면, 터지는 순간에 발생되는 에너지에 의해 오염물질이 분해 및 벽면에서 탈리되는 것이다.When the cavity that has been moved as described above comes into contact with the wall or pollutants of the laundry outer tub 2 or the laundry tub 3, the pollutants are decomposed and detached from the wall by the energy generated at the moment of bursting.

상기와 같은 세탁기의 세정작업은 세탁기의 모든 세탁과정이 완료된 후에 실시할 수도 있으며, 급수되는 물을 절약하기 위해 세탁물의 헹굼이나 탈수과정에서 수행할 수도 있는 것이다.The washing operation of the washing machine as described above may be performed after all washing processes of the washing machine are completed, or may be performed in the washing or dehydration process of the laundry to save water to be supplied.

여기서, 상기의 세정작업은 사용자가 조작부(11)를 직접조작하여 초음파 발생장치(6)를 동작시킬 수도 있으며, 사용자가 임의로 세정작업을 실시해야할 시간 및 과정의 구간을 설정하여 제어부(12)에 입력시키고, 설정된 시간이나 구간에 도달하면 제어부(12)에서 초음파 발생장치(6)를 작동시킬 수도 있다.Here, the cleaning operation may be operated by the user directly to the operation unit 11 to operate the ultrasonic wave generator 6, and to set the time and the interval of the process for the user to perform the cleaning operation arbitrarily to the control unit 12 When the input unit reaches the set time or section, the controller 12 may operate the ultrasonic wave generator 6.

또한, 상기와 같은 캐비티는 일반 세탁과정에서 세제를 용해시키는 기능을 수행할 수 있기 때문에 일반 세탁시 초음파 발생장치(6)를 동작시키면 보다 향상된 세탁효율을 얻을 수 있으며, 동시에 전술된 세탁조(2, 3)가 세정되는 작업이 수행될 수 있는 것이다.In addition, the cavity as described above can perform the function of dissolving detergent in the general washing process, so that the operation of the ultrasonic generator 6 during normal washing can obtain a more improved washing efficiency, and at the same time the washing tank (2, 3) can be cleaned.

이상에서 설명된 것과 같이 본 발명은, 세탁내조 및 세탁외조에 잔류하는 오염물질이 초음파에 의해 쉽게 제거될 수 있도록 하므로써 세탁기가 항상 청결한 상태가 유지되도록 함과 동시에 세탁시마다 세탁물이 항상 청결할 수 있도록 하여 인체에 끼쳐지는 악영향이 해소되도록 하는 효과가 발생된다.As described above, the present invention, so that the contaminants remaining in the washing tank and the washing tank can be easily removed by ultrasonic so that the washing machine is always kept clean and at the same time the laundry is always clean every time. Therefore, the effect that the adverse effects on the human body to be resolved is generated.

또한, 상기 초음파에 의해 세탁세제가 쉽게 분해되어 물과 용해되도록 하므로써 세탁효율을 향상시킬 수 있도록 하는 효과를 얻을 수 있게 된다.In addition, it is possible to obtain an effect of improving the washing efficiency by allowing the laundry detergent to be easily decomposed and dissolved with water by the ultrasonic waves.
