Description

저주파 진동 세탁기의 세탁장치Low frequency vibration washer washing machine

본 발명은 저주파 진동세탁기의 세탁장치에 관한 것으로서, 더욱 상세하게는 저주파 진동세탁기의 세탁시 수류를 난류화시켜 세탁 성능 및 효율을 향상시킬 수 있도록 한 것이다.The present invention relates to a washing machine of a low frequency vibration washing machine, and more particularly, to improve the washing performance and efficiency by turbulent water flow during washing of the low frequency vibration washing machine.

일반적으로, 저주파 진동 세탁기는 세탁조 내에 있는 물과 세제 및 공기층으로 구성된 다상매질에 진동자를 이용하여 공진현상을 일으켜 이 때 발생되는 다상매질내의 미소 공기방울들의 공동화 현상 또는 비선형 진동에 의한 기계적인 에너지와 세제에 의한 화학적인 작용에 의해 세탁 및 세척 기능을 수행하게 된다.In general, a low frequency vibration washing machine uses a vibrator in a multiphase medium composed of water, detergent and air in a washing tank to cause resonance, and mechanical energy due to cavitation or nonlinear vibration of micro air bubbles in the multiphase medium is generated. The washing and washing functions are performed by the chemical action of the detergent.

종래의 저주파 진동세탁기는 제1도에 나타낸 바와 같이, 물과 세제 및 공해층으로 구성된 다상매질을 수용하는 세탁조(1a) 내의 하부에 리니어모터등으로 된 구동수단(도시는 생략함)의 구동축(5)이 설치되고, 상기 세탁조(1a)내의 구동축(5)상단에는 세탁조(1a)내에 수용된 다상매질에 공진현상을 일으키는 저주파 발진용 진동자(2)가 설치되며, 상기 세탁조(1a) 외주면에는 진동자(2)의 발진에 따라 공진하여 세탁물과 세제 및 세탁수의 혼합유동이 원할하게 되도록 하기 위한 레조네이터(6)(resonator)가 장착되어 구성된다.As shown in FIG. 1, a conventional low frequency vibration washing machine includes a drive shaft of a driving means (not shown) formed of a linear motor or the like in a lower portion of a washing tank 1a containing a multiphase medium composed of water, a detergent, and an air pollution layer. 5) is installed, the upper end of the drive shaft (5) in the washing tank (1a) is provided with a low frequency oscillator (2) for generating a resonance phenomenon in the multi-phase medium accommodated in the washing tank (1a), the vibrator on the outer peripheral surface of the washing tank (1a) A resonator 6 is mounted to resonate in accordance with the oscillation of (2) so as to smoothly mix the laundry, the detergent and the wash water.

따라서, 세탁조(1a) 내에 장착된 진동자(2)와 레조네이터(6)의 상호작용에 의한 세탁물의 움직임을 제어하므로써 세탁물과 세액매질 사이에 발생된 상대속도와 공진시에 발생된 다상매질내에서의 미소공기 방울들의 운동에너지로 세탁을 하게 된다.Therefore, by controlling the movement of the laundry by the interaction of the vibrator 2 and the resonator 6 mounted in the washing tank 1a, the relative velocity generated between the laundry and the washing medium and the polyphase medium generated at the resonance are generated. Washing with kinetic energy of micro air bubbles

즉, 이와같은 조건에서 세탁물은 세탁조(1a)의 내벽에 붙었다, 떨어졌다하는 동작과 공진시의 상하방향 수류분포에 따라 상하방향의 운동을 함으로써 수류와 세탁물 사이의 상대속도차가 커지게 되어 수류에 의한 세탁작용과 공진시 매질 내부에 미소공기방울들의 운동에너지에 의한 세탁작용등이 합쳐져서 세탁성능을 발휘하게 된다.That is, under such conditions, the laundry adheres to the inner wall of the washing tank 1a. The relative speed difference between the water flow and the laundry increases by moving up and down in accordance with the up and down water flow distribution during resonance. When washing and resonating by the combination of the washing action by the kinetic energy of the air bubbles inside the medium to achieve the washing performance.

그러나, 이와 같은 종래의 저주파 진동세탁기는 세탁에 필요한 에너지의 효율적 공급 측면에서 일정한 진동자(2)의 운동시 세탁효과를 극대화 하기 위해, 세탁조(1a)의 외주면에 장착된 레조네이터(6)에 의해 세탁물이 붙었다, 떨어졌다 하는 동작을 하게 되는데, 세탁조(1a) 외주면의 중앙부분에 설치된 레조네이터(6)는레조네이터(6) 내부와 세탁조(1a) 내부 사이의 압력차이가 제1도와 같이 크지 않기 때문에 세탁효과가 저하되었다.However, such a conventional low frequency vibrating washing machine uses laundry by the resonator 6 mounted on the outer circumferential surface of the washing tub 1a in order to maximize the washing effect during the movement of the constant vibrator 2 in terms of efficient supply of energy required for washing. The resonator 6 installed at the center of the outer circumferential surface of the washing tank 1a has a large pressure difference between the inside of the resonator 6 and the inside of the washing tank 1a. The effect was reduced.

또한, 세탁물을 잡아주려고 하는 레조네이터(6)의 작용이 없을 때, 세탁물과 세액사이의 상대속도는 세액속도의 10% 이하로 나타나므로 인해, 진동자(2)의 운동에 의한 세탁조(1a) 내부에 다상매질의 공진시 분포된 수류속도가 세탁조(1a)의 중앙부분은 제1도에 도시된 바와 같이 매우 크게 나타남에 따라 에너지의 사용이 많아지게 되는 등의 문제점이 있었다.In addition, when there is no action of the resonator 6 to hold the laundry, the relative speed between the laundry and the tax solution appears to be 10% or less of the tax rate, so that the inside of the washing tank 1a by the movement of the vibrator 2 As the water flow velocity distributed during the resonance of the polyphase medium is very large, as shown in FIG. 1, the central portion of the washing tank 1a has a problem such that the use of energy increases.
