본 고안은 초음파 세탁기에 관한 것으로, 특히 세탁조에 진동자 케이스를 부착하고 그 진동자 케이스에 진동자를 부착하여 진동자의 효율을 증대시킨 초음파 세탁기의 진동자 출력 감소 방지장치에 관한 것이다.The present invention relates to an ultrasonic washing machine, and more particularly, to an apparatus for preventing oscillator output reduction of an ultrasonic washing machine, in which a vibrator case is attached to a washing tank and a vibrator is attached to the vibrator case to increase the efficiency of the vibrator.
종래의 초음파 세탁기는 제1도와 같이 세탁조(1)의 측면에 진동판(2)이 부착되고, 그 진동판(2)에 진동자(3)가 직접 부착되어 있으며, 진동자(3)가 진동자 제어부(4)에 연결되어 있다.In the conventional ultrasonic washing machine, the diaphragm 2 is attached to the side surface of the washing tank 1 as shown in FIG. 1, the vibrator 3 is directly attached to the diaphragm 2, and the vibrator 3 is the vibrator controller 4. Is connected to.
이러한 초음파 세탁기는 통상의 교반식 세탁기와 같이 모터(5)의 구동에 의하여 교반기(6)가 회전하면 세탁조(1)내에 물과 세탁물이 교반되어 세탁이 행하여지면서 제어부(4)에 의해 제어되는 진동자(3)가 초음파를 발생시켜 세탁성능을 향상시키게 된다.The ultrasonic washing machine is a vibrator controlled by the control unit 4 while the washing machine is performed by washing the water and the laundry in the washing tank 1 when the stirrer 6 is rotated by the driving of the motor 5 like a conventional stirring washing machine. (3) generates ultrasonic waves to improve washing performance.
이때 진동자(3)에 의한 초음파 출력(P)은 제2도에 보인 바와같이 양단의 전류(I)와 전압(V)에 의하여 결정된다.At this time, the ultrasonic output P by the vibrator 3 is determined by the current I and the voltage V at both ends, as shown in FIG.
P=V·I ………………………(1)P = V · I... … … … … … … … … (One)
이 때 진동자(3)에 걸리는 전압은 진동자(3)의 제어부(4)가 전압원으로 작동하므로 항상 일정하다.At this time, the voltage applied to the vibrator 3 is always constant since the control unit 4 of the vibrator 3 operates as a voltage source.
또한 진동자(3)의 임피던스(Z)는 물의 유동(load)과 관련있는데 물의 유동이 크면 진동자(3)가 받는 힘(Fn)이 증가하고 그 결과 임피던스(Z)가 증가되며 진동자(3)의 출력은 감소된다.In addition, the impedance Z of the vibrator 3 is related to the load of water. When the flow of water is large, the force Fn of the vibrator 3 increases, and as a result, the impedance Z increases and the vibration of the vibrator 3 increases. The output is reduced.
제2도와 같이, 물의 유동이 없는 경우 보다 물의 유동이 생기고 그 결과 진동자(3)가 받는힘(Fn)의 증가로 진동자(3)의 임피던스(Z)가 증가된 경우의 전류(I')는 현저하게 줄어든다. 따라서 모터(5)가 회전할 때의 초음파 출력은 감소되어 전체적인 초음파에 의한 세탁효율이 저하된다.As shown in FIG. 2, the current I 'is generated when the impedance Z of the vibrator 3 is increased due to an increase in the force Fn received by the vibrator 3 as a result of the flow of water more than there is no flow of water. Significantly reduced. Therefore, the ultrasonic power output when the motor 5 rotates is reduced, so that the washing efficiency due to the ultrasonic waves as a whole decreases.
이상에서 설명한 바와같이 종래 초음파 세탁기는 세탁조(1)의 측면에 부착한 진동판(2)에 진동자(3)를 직접 고정하였으므로 초음파에 의한 세탁효율이 저하되는 결함이 있었다.As described above, in the conventional ultrasonic washing machine, since the vibrator 3 is directly fixed to the diaphragm 2 attached to the side surface of the washing tank 1, there is a defect that the washing efficiency due to the ultrasonic wave is lowered.
본 고안은 제3도 내지 제5도에 도시한 바와같이, 세탁조(1) 측면의 세탁수면 아래에 형성한 개구부(1a)외측에 진동자 케이스(7)과 부착되어 있고 그 진동자 케이스(7)의 밑면(8)에 진동자(3')가 부착되어 있다. 진동자 케이스(7)는 그 윗면(9)이 θ각을 가지고 기울어져 있고 앞면(10)에는 물의 흐름이 가능하도록 통공(11)이 천공되어 있으며 밑면(8)에 진동자(3')가 부착 고정되게 고정공(12)이 형성되고 나머지 3면은 막혀 있는 6면체의 구조로 되어 있다.The present invention, as shown in FIGS. 3 to 5, is attached to the vibrator case (7) outside the opening (1a) formed under the washing surface of the side of the washing tank (1), and the vibrator case (7) The vibrator 3 'is attached to the bottom surface 8. The vibrator case 7 is inclined at an upper surface 9 with an angle of θ, and the front surface 10 is perforated with a hole 11 to enable water flow, and the vibrator 3 'is fixed to the bottom surface 8. Fixing hole 12 is formed so that the remaining three surfaces are blocked in a hexagonal structure.
도면에서 13, 14는 볼트와 너트를 보인 것이며, 2'는 진동판이다.13 and 14 show bolts and nuts, and 2 'is a diaphragm.
제4도를 참조하면 상기 θ는 다음과 같다.Referring to FIG. 4, θ is as follows.
이와같은 본 고안은 종래 세탁기와 같이 모터(5)의 구동에 의해 교반기(6)가 회전함에 따라 물과 세탁물이 교반되고 구동제어부(4)에 의해 제어되는 진동자(3')에서 초음파가 발생되면서 세탁이 행하여진다. 그러나, 본 고안은 세탁조(1)의 측벽에 진동자 베이스(7)를 부착하고 그 진동자 케이스(7)의 밑면(8)에 진동자(3')를 부착하였으므로, 종래에 비하여 진동자(3')의 효율이 개선되어 세탁력이 향상된다.The present invention as described above, as the stirrer 6 is rotated by the driving of the motor 5, as in the conventional washing machine, water and laundry are agitated and ultrasonic waves are generated in the vibrator 3 'controlled by the drive control unit 4. Washing is performed. However, since the present invention attaches the vibrator base 7 to the side wall of the washing tank 1 and the vibrator 3 'to the bottom surface 8 of the vibrator case 7, the vibrator 3' Efficiency is improved and washing power is improved.
이하, 이러한 진동자(3')의 효율 개선작용을 제4도를 참조하여 살펴보면, 세탁이 행하여지는 때에 이미 앞에서 언급한 바와같이, 세탁조(1)의 측면에 힘(Fn)을 가하게 된다.Hereinafter, referring to FIG. 4, the efficiency improvement effect of the vibrator 3 ′ will be applied to the side of the washing tub 1 when the washing is performed, as described above.
이 때 진동자 케이스(7)의 앞면(10)을 통과한 힘(Fn)은 진동자 케이스(7)의 윗면(9)에서 반사되는 힘 Fn'과 Fn"의 합성이 된다고 가정하면 이 두힘의 합인 Fn'"는 이상적으로 소실이 없는 상태에서는 Fn과 같거나 작다고 볼 수 있다. 진동자의 임피던스를 결정하는 외부의 힘은 진동자면과 직각으로 들어오는 힘으로 이것이 제4도에서 Fo에 해당하면 이 Fo는 Fn 보다 필연적으로 작다.At this time, assuming that the force Fn passing through the front surface 10 of the vibrator case 7 is a combination of the forces Fn 'and Fn "reflected from the top surface 9 of the vibrator case 7, Fn which is the sum of these two forces. '"Is ideally equal to or less than Fn in the absence of loss. The external force that determines the impedance of the vibrator is the force coming in at right angles to the vibrator surface. If this corresponds to Fo in Fig. 4, this Fo is inevitably smaller than Fn.
따라서이 되어서 종래의 세탁기 구조인 제1도 보다 진동자(3')의 출력이 증가된다.therefore This results in an increase in the output of the vibrator 3 'than in FIG. 1, which is a conventional washing machine structure.
한편 진동자(3')에서 발생하는 초음파는 진동자 케이스(7)내에서 세제의 유화작용등의 세탁작용을 하고 일부는 진동자 케이스 윗면(9)에 반사되어 진동자 케이스 앞면(10)을 통과하여 세탁조(1)안으로 들어가게 되어 종래의 초음파 세탁기와 동일한 역할을 행한다.On the other hand, the ultrasonic waves generated from the vibrator 3 'washes, such as emulsification of detergent in the vibrator case 7, and is partially reflected by the upper surface 9 of the vibrator case to pass through the vibrator case front surface 10 to wash the tub ( 1) It enters and plays the same role as the conventional ultrasonic washing machine.
이와같은 본 고안은 제5도에서 보인 바와같이 물의 유동에 따른 전류의 변화가 거의 없으며 이는 진동자(3')의 임피던스(Z)가 크게 변하지 않기 때문이며 이는 근본적으로 진동자 케이스(7)가 물의 흐름에 의한 진동자(3')에 부가되는 힘을 감소시키기 때문이다. 전류의 감소가 적어지면 진동자의 출력감소가 줄어들고 결과적으로 세탁성능이 향상되는 이점이 있다.As shown in FIG. 5, the present invention has almost no change in current due to the flow of water, because the impedance Z of the vibrator 3 'does not change significantly, which is basically because the vibrator case 7 This is because the force added to the vibrator 3 'is reduced. Less current decreases the output power of the oscillator, resulting in improved wash performance.
