In addition, a water storage tank 6 having a space formed on the inner circumferential surface of the lower portion of the washing tank 1 by pressing the dehydration object with the pressing plate 4 when the dewatering object is held through the plurality of dehydration holes 5 formed on the upper portion thereof. It is formed integrally, the lower center in the washing tank (1) is provided with a washing disk (7) for washing by generating a non-linear resonance in the polyphase medium accommodated in the washing tank (1), the outer peripheral surface of the end of the washing disk (7) Alternatively, between the outer circumferential surface of the drive shaft connected to the lower part of the washing disc and the water storage tank 6 in the lower part of the washing tank 1, the lower space of the washing disc 7 and the washing degree 1 space are shielded to prevent leakage of air or water. A disk sealer 8 is installed to prevent this.

In addition, on the outer circumferential surface of the water storage tank 6 on the washing disc 7 to prevent the laundry between the pressing plate 4 and the washing disc 7 from being damaged by the washing disc 7 reciprocating during washing and dehydration. A dehydration net 9 is installed, and a drive shaft 11 is installed between the washing disc 7 and the driving unit 10 to oscillate the washing disc 7 by receiving power from the driving unit 10.

In addition, the drive shaft 11 between the washing disk 7 and the drive unit 10 is provided with a housing 12 for maintaining airtightness while supporting and guiding the reciprocating motion of the drive shaft 11, and the drive shaft in the housing 12. A compression disk 13 is installed at 11 so that the fluid pressure divided according to the reciprocating motion of the drive shaft 11 is generated with a positive pressure (+) and a negative pressure (-) generated in cooperation with the drive shaft 11. .

In addition, a water supply valve 14 for supplying water into the washing tank 1 is connected to an upper portion of one side of the washing tank 1, and the other side of the washing tank 1 moves air in the washing tank 1 sealed when water is supplied to the outside. A vent valve 15 for discharging is connected, and a drain valve 16 for draining water in the washing tank 1 is installed at a lower side of the water storage tank 6 so that the pressure difference is narrow. The pipe 17 is connected to the drain pipe 18 together with the exhaust valve 15.

In addition, a lower side of one side of the washing tank (1) is connected to the first air supply valve (19) for introducing a small amount of air in the vicinity of the washing disk (7) during the initial washing, one side of the washing tank (1) when dewatering Second air supply valve 20 for supplying air to the bellows (3) is connected, each of the first and second intake and shutoff valves (12) for opening and washing the air in the housing (12) to the housing (12) 21) 22 are connected.

In the housing 12, first, second, third and fourth check valves 23 for allowing fluid to flow in one direction to suck and compress an external fluid according to the reciprocating motion of the compression disk 13 to be supplied to another place, respectively. (24) (25) (26) are connected, and the first and second check valves (23) and (24), respectively, are four port two position first direction switching valves 27 for controlling the flow of fluid in a predetermined direction depending on the position. ) And the three port two-position second directional valve 28 are connected.

As shown in FIG. 2 and FIG. 3, the present invention configured as described above opens the lid 2 installed on the upper part of the washing tank 1 when water is supplied to the low frequency vibrating separator, and closes the lid 2 after the laundry is introduced. In this case, the bellows 3 installed in the lower part of the lid 2 stays in the washing tank upper space in a contracted state without being inflated, and the first and second intake shutoff valves 21 and 22 and the drain valve 16 are closed. ) And the first and second air supply valves 19 and 20 are closed, and the water supply valve 14 on one side of the washing tank 1 and the discharge valve 15 on the other side of the washing tank 1 are opened.

Accordingly, water is supplied to the inside of the washing tank 1 through the water supply valve 14 connected to the water supply, so that the air in the closed space in the washing tank 1 escapes to the atmosphere by the volume of the water introduced through the exhaust valve 15. To achieve a water supply administration.

In addition, during washing, the first and second intake shielding valves 21 and 22 are opened, and the drain valve 16, the exhaust valve 15, the water supply valve 14, and the first and second air supply valves 19 ( 20 is closed, the four-port two-position first directional valve 27 connected to the first check valve 23 is in the position P1, and the second directional directional valve 28 connected to the second check valve 24 is closed. ) Becomes the position of P3.

Therefore, the power is transmitted to the washing disc 7 through the drive shaft 11 in accordance with the driving of the drive unit 10 to perform a reciprocating lifting movement, and in the washing tank 1 nonlinear resonance is generated to wash.

On the other hand, the air inside the housing 12 according to the up and down movement of the compression disk 13 installed in the drive shaft 11 in the housing 12 is repeated inflow and outflow, the compression disk 13 will rise In this case, since the lower part of the housing 12 has a low pressure, air flows in as much as the stroke volume of the compression disk 13 through the first intake / charging valve 21 and the first check valve 23, and the upper part of the housing 12 On the contrary, the air is compressed as much as the volume, but only the second intake blocking valve 22 is opened so that the air flows out through the second intake blocking valve 22.

On the contrary, the second intake shielding valve 22 and a part of the second intake shielding valve 22 are introduced into the housing 12 through the third check valve 26 and flow out through the first intake blocking valve 21. Since the second direction switching valve 28 connected to (24) is at P3, the air passing through the second check valve (24)-> B-> T1 is blocked by the second air supply valve (20) so that there is no flow.

In addition, in the first stage of dehydration after washing, the drain valve 16 and the second air supply valve 20 are opened, and the first and second intake shield valves 21 and 22, the water supply valve 14, and the first The 1st and 2nd air supply valves 19 and 20 are closed, the 1st direction switching valve 27 is located in P1, and the 2nd direction switching valve 28 is in the position of P3.

Therefore, when the compression disk 13 is lowered, the lower part of the housing 12 receives the positive pressure (+), the upper part of the negative pressure (−), and repeatedly occurs, and when the lower pressure is (+), the second check valve Air is filled into the bellows 3 of the lower part of the lid 2 through the second air supply valve 20 through B-> T1 through 24, and the upper part of the housing 12 is negative (-). Air is introduced through the third check valve 26.

On the contrary, when the lower part in the housing 12 becomes (−), air flows into the lower part of the housing 12 through the first check valve 23, and the upper part is (+), so the fourth check valve 25 Through the drain pipe 18 is passed through.

At this time, since the drain valve 16 connected to the drain pipe 18 is installed in the venturi pipe 17, when the air flows through the volleyball pipe 18 faster, the venturi pipe 17 causes a pressure difference to cause the washing tank ( 1) The water in the washing tank 1 is drained through the dehydration hole 5 on the water storage tank 6 formed integrally on the inner peripheral surface of the lower portion.

If this process is repeated for a certain time, the inside of the bellows (3) is expanded to a high pressure so that the pressing plate (4) at the bottom of the bellows (3) presses the laundry, and from the drain valve 16 due to the continued venturi effect Since the inside of the washing tank 1 sucks air, the inside of the washing tank 1 becomes (-), so that the dehydration efficiency can be improved.

In addition, in the second stage of dehydration, when the internal pressure of the bellows 3 becomes higher than the set pressure in the first stage of dehydration, the internal pressure of the bellows 3 is changed as the second directional valve 24 is switched from P3 to P4. Without increasing, the laundry is continuously pressed under the high pressure, and the air supplied into the bellows 3 through the second check valve-> B-> T1 is supplied to the second check valve 24-> N1. Through the third check valve (25)-> the fourth check valve (26) and the air flowing through the drain pipe 18 repeatedly with each other, the venturi effect of the drain pipe 18 is higher than in the first stage of dehydration, so dehydration The efficiency can be maximized.

Then, when the dehydration stroke is completed, the first and second intake shielding valves 21 and 22 are closed, and the drain valve 16, the exhaust valve 15, and the second air supply valve 20 are opened. The one-way valve 27 is located at P2, and the second directional valve 28 is located at P3.

In this case, the air inside the bellows 3 is discharged to the outside through the first check valve 23 through the second check valve 24-> B-> A1 by the first direction change valve 27. Since the exhaust valve 15 is open, the inside of the washing tank 1 is kept at atmospheric pressure, and the bellows 3 is contracted without any resistance to the original position at the time of water supply, thereby completing the process of water supply-> washing-> dehydration. Done.

On the other hand, if artificially put a small amount of air near the washing disk (7) in the washing tank (1) at the beginning of the washing, the input energy and load can be reduced, and the non-linear resonance phenomenon is generated easily, The first and second intake and shutoff valves 21 and 22 are opened, and the drain valve 16, the exhaust valve 15, the water supply valve 14 and the first and second air supply valves 19 and 20 are flushed. The air flows into the washing tank 1 in a short time through the second air supply valve 20 while the first direction switching valve 27 is positioned at P1 and the second direction switching valve 20 is located at P3. It can be put in.

In addition, since the dehydration net 9 is installed on the outer circumferential surface of the storage tank 6 on the washing disc 7, the washing disc 7 reciprocates the laundry between the pressing plate 4 and the washing disc 7 during washing and dehydration. It is possible to prevent damage by.

As described above, the present invention is effective to maintain the balance without generating a friendly force during dehydration as a washing tank 1 without installing a pressure reduction and pressure device having a separate drive source as the drive unit 10 of the low frequency vibration washing machine It is a very useful invention that can greatly improve the efficiency and reliability of the product because it can carry out the dehydration, can greatly increase the washing efficiency by reducing unnecessary water consumption.
