본 발명은 저주파 진동 세탁장치에 관한 것으로서, 더욱 상세하게는 저주파 진동 세탁장치에 의해 세탁을 할 때 진동하는 물의 에너지 손실을 줄여 세탁효율을 향상시킬 수 있도록 한 것이다.The present invention relates to a low frequency vibration washing apparatus, and more particularly, to reduce the energy loss of the vibrating water when washing by the low frequency vibration washing apparatus to improve the washing efficiency.

저주파 진동 세탁장치는 세탁조 내에 있는 물과 세제 및 공기층의 복합체인 다상 매질에 세탁조의 형상과 디스크의 형상 및 다상매질의 구성비등에 따라 특정 주파수로 공전 현상을 일으켜 이때 발생하는 다상매질내의 미소 공기방울들의 공동화현상(Cavitation Phenomena) 또는 비선형 진동(Nonlinear Oscillatin)에 의한 기계적 에너지와 세제에 의한 화학적인 작용의 결합에 의해 세탁을 수행하는 장치로서 공진에 필요한 최소의 에너지를 투입하여 효율적인 세탁을 할 수 있다는 장점이 있다.The low frequency vibration washing machine generates a revolving phenomenon at a specific frequency depending on the shape of the washing tank, the shape of the disk and the composition ratio of the polyphase medium in the polyphase medium, which is a complex of water, detergent and air layer in the washing tank. A device that performs washing by combining mechanical energy by cavitation phenomena or nonlinear oscillatin and chemical action by detergent, which can efficiently wash by inputting minimum energy required for resonance. There is this.

제1도는 종래의 저주파 진동 세탁장치를 나타낸 종단면도로서, 물과 세제와 공기층으로 구성된 다상매질을 수용하는 세탁조(1)내의 하부에 액츄에이터(Actuator)(2)의 구동축(3)이 관통하여 설치되고, 상기 세탁조(1)내의 구동축(3)상단에는 액츄에이터(2)의 구동에 의해 세탁조(1)내에 수용된 다상매질에 공진현상을 일으키는 저주파 발전용 디스크(4)가 설치되며, 상기 액츄에이터(2)에는 변위진폭신호와 주파수 신호를 보내는 신호발진부(7)와 신호를 증폭하여 가변시키는 신호증폭부(8)가 연결된다. 또한 세탁조(1)의 상부에는 세탁조 내부를 밀폐공간으로 만들기 위한 밀폐관(9)이 설치되어 구성된다.FIG. 1 is a longitudinal sectional view showing a conventional low frequency vibration washing machine, in which a drive shaft 3 of an actuator 2 penetrates a lower portion of a washing tank 1 containing a multiphase medium composed of water, detergent, and air layer. At the upper end of the drive shaft 3 in the washing tank 1, a low frequency power generating disk 4 is provided which causes resonance in the polyphase medium accommodated in the washing tank 1 by driving the actuator 2, and the actuator 2 ) Is connected to a signal oscillator 7 for transmitting a displacement amplitude signal and a frequency signal and a signal amplifier 8 for amplifying and varying the signal. In addition, the upper part of the washing tank 1 is provided with a sealed tube 9 for making the inside of the washing tank into a closed space.

따라서, 액츄에이터(2)에 연결된 신호발진부(7) 및 신호증폭부(8)의 신호에 의해 액츄에이터(2)가 구동하면 세탁조(1)내의 구동축(3)상단에 설치된 저주파 발진용 디스크(4)가 발진을 하면서 세탁조(1)내에 있는 물과 세제 및 공기층으로 구성된 다상매질에 공진현상이 발생하여 수류가 형성되고 이때 발생되는 미소 공기방울들의 공동화 현상 또는 비선형 진동에 의한 기계적인 에너지와 세제의 화학적인 작용이 결합되어 세탁물이 수류를 따라 이동하면서 세탁작동이 수행된다. 이때 신호증폭부(8)와 신호발진부(7)는 저주파 발진용 디스크(4)의 발진주파수 대역이 20∼250Hz에서 진폭이 2∼25mm, 회전방향 각 진폭이 2∼10°의 범위내에 오도록 하여 디스크(4)에 인가되는 전류 또는 전압을 증폭시키는 역할을 하게된다.Therefore, when the actuator 2 is driven by the signal of the signal oscillation unit 7 and the signal amplifier 8 connected to the actuator 2, the low frequency oscillation disk 4 installed on the drive shaft 3 in the washing tank 1 The oscillation occurs in the multiphase medium composed of water, detergent and air layer in the washing tank (1), and the water flow is formed, and mechanical energy and detergent chemicals by cavitation or nonlinear vibration of micro air bubbles generated at this time are generated. The phosphorus action is combined to perform the laundry operation while the laundry moves along the water stream. At this time, the signal amplifier 8 and the signal oscillator 7 are arranged so that the oscillation frequency band of the low frequency oscillation disk 4 is within a range of 2 to 25 mm in amplitude and 2 to 10 degrees in each rotational direction at 20 to 250 Hz. It serves to amplify the current or voltage applied to the disk (4).

또한 상기와 같은 저주파 진동 세탁장치에서 구동축(3) 상단에 설치된 디스크(4)의 발진에 의해 물이 진동을 함에 따라 물은 진동에너지를 갖게되는데, 종래 저주파 진동 세탁장치에서는 진동하는 물의 에너지 손실에 대한 고려가 없기 때문에 물이 디스크(4)에 부딪칠 때 물이 갖고 있는 에너지를 순간적으로 잃어버리게 되어 다음 순간 새로운 운동방향과 속도를 가지게 되므로 에너지 손실이 발생하게 되는 문제점이 있다.In addition, as the water vibrates by oscillation of the disk 4 installed on the drive shaft 3 in the low frequency vibration washing machine as described above, the water has vibration energy, and in the conventional low frequency vibration washing machine, Since there is no consideration, water loses its energy momentarily when it hits the disk 4 and has a new direction and speed of motion the next time, causing energy loss.

본 발명은 저주파 진동 세탁장치에 의해 세탁을 할 때 세탁조에서 진동하는 물의 에너지 손실을 줄여 효과적인 진동을 시키므로써, 세탁효율을 향상시킬수 있는 저주파 진동 세탁장치를 제공하는데 그 목적이 있다.An object of the present invention is to provide a low-frequency vibration washing machine that can improve the washing efficiency by reducing the energy loss of the water vibrating in the washing tank when washing by the low-frequency vibration washing machine to improve the washing efficiency.

상기한 목적을 달성하기 위한 본 발명의 실시예에 따라 세탁조에 디스크의 진동시 물이 접촉하여 손실되는 에너지를 탄성 에너지로 보존하기 위한 탄성수단이 내장된 저주파 진동 세탁장치가 제공된다.According to an embodiment of the present invention for achieving the above object is provided a low-frequency vibration washing machine with a built-in elastic means for preserving the energy lost by the contact of the water in the vibration of the disk in the washing tank as elastic energy.

이하, 본 발명의 일실시예를 첨부 도면 제2도를 참조하여 상세히 설명하면 다음과 같다.Hereinafter, an embodiment of the present invention will be described in detail with reference to FIG. 2.

제2도는 본 발명의 일실시예를 나타낸 종단면도로서, 물과 세제 및 공기층으로 구성된 다상매질을 수용하는 세탁조(1)내의 하부중앙을 관통하여 리니어 모터 또는 전자기 액츄에이터로 된 구동수단(2)의 구동축(3)이 설치되고, 구동축(3)의 상단에는 상기 세탁조(1)내에 수용된 다상매질에 공진현상을 일으키는 저주파 발진용 디스크(4)가 설치되며, 디스크(4)의 상부에는 디스크(4)의 진동시 물이 접촉하여 손실되는 에너지를 탄성에너지로 보존하기 위한 탄성체(5)가 장착되고, 탄성체(5)의 내부에는 공기 또는 기체가 충진되어 구성된다.FIG. 2 is a longitudinal sectional view showing an embodiment of the present invention, in which a driving means 2 made of a linear motor or an electromagnetic actuator penetrates through the lower center of the washing tank 1 containing a multiphase medium composed of water, detergent, and air layer. A drive shaft 3 is installed, and a low frequency oscillation disk 4 for resonating phenomenon is installed at the upper end of the drive shaft 3, and the multiphase medium accommodated in the washing tank 1, and the disk 4 on the upper portion of the disk (4). An elastic body 5 is mounted to preserve energy lost by contact of water when the vibration of the vibration) occurs as elastic energy, and the inside of the elastic body 5 is filled with air or gas.

이와 같이 구성된 본 발명은 제2도에 나타낸 바와 같이, 물과 세제 및 공기층으로 구성된 다상매질을 수용하는 세탁조(1)의 하부중앙에 설치되어 리니어 모터 또는 전자기 액츄에이터로 된 구동수단(2)의 구동에 의해 상기 세탁조(1)내의 하부 중앙을 관통하여 설치된 구동수단(2)의 구동축(3) 상단의 저주파 발진용 디스크(4)가 물에 진동을 일으킴에 따라 물은 진동에너지를 갖게된다.As shown in FIG. 2, the present invention configured as described above is installed in the lower center of the washing tank 1 containing the multiphase medium composed of water, detergent, and air layer to drive the driving means 2, which is a linear motor or an electromagnetic actuator. As a result of the low frequency oscillation disk 4 on the top of the drive shaft 3 of the drive means 2 installed through the lower center of the washing tank 1, the water vibrates in the water, so that the water has vibration energy.

상기와 같은 진동에너지에 의해 물이 진동하면서 디스크(4)에 부딪칠 때 디스크(4)상에는 내부에 공기 또는 기체가 충진된 탄성체(5)가 장착되어 있으므로 이 탄성체(5)가 물이 디스크(4)에 직접 부딪쳐서 잃어버리게 되는 에너지를 흡수하여 탄성에너지로서 보존하게 된다.When the water vibrates against the disk 4 while vibrating by the vibration energy as described above, the elastic body 5 filled with air or gas is mounted on the disk 4, so that the elastic body 5 has a water disk ( It absorbs the energy lost by directly hitting 4) and preserves it as elastic energy.

즉 세탁조 내의 물이 하방으로 이동할 때에는 탄성체(5)가 수축되면서 에너지를 흡수하고 반대로 물이 상방으로 이동할 때에는 수축되어 있던 탄성체(5)가 팽창하면서 흡수하였던 에너지를 방출해주게 되며, 이와 같은 작동에 의해 물의 진동에 따른 에너지 손실을 최소한으로 줄여 효과적으로 진동이 일어나게 하여준다.That is, when the water in the washing tank moves downward, the elastic body 5 is contracted to absorb energy. On the contrary, when the water moves upward, the elastic body 5 is expanded and releases the energy absorbed by the expansion. The energy loss caused by the vibration of the water is minimized to effectively cause the vibration.

제3도는 본 발명의 다른 실시예로서, 저주파 진동 세탁장치의 세탁조(1) 바닥면에 공기나 기체가 내장된 고무튜브(6)를 장착시킨 구성으로 되어 있다.3 shows another embodiment of the present invention in which a rubber tube 6 in which air or gas is embedded is mounted on the bottom surface of the washing tank 1 of the low frequency vibration washing machine.

이 실시예에서는 구동수단(2)에 의해 디스크(4)가 세탁조(1)내의 물에 진동을 일으킴에 따라 세탁조(1)에 물이 직접 부딪쳐서 손실되는 에너지가 상기 고무튜브(6)에 의해 탄성 에너지로 보존되므로 이에 상당하는 에너지를 다시 재사용할 수 있어서 압력에너지는 보존되는 에너지만큼 작게되고, 공진을 발생시키는데 필요한 에너지를 보다 작은 주파수로부터 얻을 수 있을 뿐만 아니라, 공진발생시간을 단축시킬 수 있게 된다.In this embodiment, as the disk 4 vibrates the water in the washing tank 1 by the driving means 2, energy lost by directly hitting the washing tank 1 by the rubber tube 6 is elasticized by the rubber tube 6. Since it is conserved as energy, the corresponding energy can be reused again, so that the pressure energy is as small as the energy conserved, and the energy required to generate resonance can be obtained from a smaller frequency, and the resonance generation time can be shortened. .

이상에서와 같이, 본 발명은 저주파 진동 세탁장치의 다상매질을 수용하는 세탁조(1)의 내부에 저주파 발진용 디스크(4)의 진동시 물이 접촉하여 손실되는 에너지를 탄성에너지로 보존하기 위한 탄성수단을 장착함에 따라 세탁시 에너지 손실을 줄여 효율적으로 입력에너지를 재사용할 수 있게 된다.As described above, the present invention is an elasticity for preserving the energy lost by the contact of water during the vibration of the low frequency oscillation disk (4) inside the washing tank (1) containing the multi-phase medium of the low frequency vibration washing machine as elastic energy By mounting the means, it is possible to efficiently reuse the input energy by reducing energy loss during washing.

또한 에너지 손실이 감소됨에 따라 공진을 낮은 주파수에서 발생시킬 수 있고 공진발생시간을 단축시켜 세탁효율을 향상시킬 수 있게 된다.In addition, as the energy loss is reduced, resonance can be generated at a low frequency, and the resonance generation time can be shortened to improve washing efficiency.
