The power drive unit 40 includes a motor 41 and a clutch 42 mounted on the lower outer surface of the water tank 20. The clutch 42 is fixed to the lower center of the water tank 20 so as to transfer power to the rotating tank 50 and the pulsator 90, and the end of the rotating shaft 43 thereof is the rotating tank 50 and the pulsator 90. ) Is combined with the central part. Accordingly, only the pulsator 90 is rotated forward and reverse during washing and rinsing stroke by the clutch 42, and the pulsator 90 and the rotating tank 50 are simultaneously rotated in one direction during the dehydration stroke. The motor 41 generates power and transmits the power to the clutch 42. To this end, the pulley 411 of the motor 41 and the pulley 421 of the clutch 42 are connected to each other via a belt 44. .

The rotating tank 50 in which the pulsator 90 is built is provided with a cylindrical cylindrical body 51 having an upper and lower portions and a lower body 52 having a plate shape, so as to maintain a constant distance from the inner wall of the water tank 20. Is installed.

The balancer 60 buffers vibrations during washing and rinsing strokes of the washing machine through a wave of brine, and maintains a balance of the rotating tank 50 during dehydration strokes.

3 and 4, the dehydration hole 511 is locally drilled only at the upper end of the cylindrical body 51, and the inner wall thereof is provided with rising ducts 512 and 513 in the vertical length direction, thereby rotating. Washing and rinsing administration may be performed while washing water is stored only in the tank 50.

That is, the dehydration hole 511 is perforated spaced apart in the circumferential direction along the edge adjacent to the lower end of the balancer 60, which discharges the water guided upward along the inner wall of the rotating tub 50 during the dehydration stroke to the outside. It is to. The ascending duct has a pair of ascending induction roads 512 provided convexly protruding outward from the rotary tub 50 and symmetrically with respect to the rotary tub 50, and an induction furnace cover 513 covering them. The rising induction road 512 formed to have a predetermined width extends vertically from the bottom of the inner wall surface of the cylindrical body 51 to the upper end side, and the front surface is formed to be open. The induction furnace cover 513 coupled to cover the open front surface of the upward flow path 512 is formed of a plastic injection molding, and is the same surface as the inner wall surface of the cylindrical body 51 adjacent to both ends of the upward flow path 512. It is fitted to hold the coupled, where a plurality of induction holes 514 are perforated. Therefore, by forming an induction space 515 between the ascending induction road 512 wall and the induction road cover 513, the water escaped by the centrifugal force during the high speed rotation of the rotating tub 50 is guided through the induction hole 514 It is introduced into the space 515 and guided to the upper end of the rotating tank 50, which will be described in detail in the operation description.

And the lower body 52 of the plate-shaped injection molded into a plastic material is, as shown in Figure 2, the outer surface portion is coupled to the lower end of the cylindrical body 51 and a plurality of wings 91 radially on its upper side portion The pulsator 90 provided with is arrange | positioned. To this end, a drainage hole 521 having a predetermined diameter is drilled in the center of the lower body 52, so that the rotating shaft 43 of the clutch 42 is coupled to the center of the pulsator 90 through the drainage hole 521. do. At this time, the drainage hole 521 is largely formed so that the rotation shaft 43 is allowed to pass through, which is to facilitate the drainage stroke to be described later. In addition, a shaft flange 522 is provided on the lower surface of the lower body 52. The central portion of the shaft flange 522 is connected to the rotary shaft 43 of the clutch 42, through which the rotary tank 50 is rotated at high speed by receiving power from the clutch 42 during dehydration and administration.

On the other hand, the lower portion of the water tank 20 is provided with a main drain hose 80 and a sub drain hose 82 for discharging the wash water to the outside of the housing 10. One end of the main drain hose 80 communicates with the water tank 20, and the other end thereof extends to the outside of the housing 10. One end of the main drain hose 80 is provided with a drain valve 81 for selectively opening and closing it. One end of the main drain hose 80 is in direct communication with the inside of the rotating tank 50 through the central drain cover 70 made of a plastic injection molding. That is, the central drain cover 70 is disposed between the bottom of the rotating tank 50 and the bottom surface of the water tank 20 so as to surround the rotary shaft 43 of the clutch 42, and is drilled in the lower portion of the rotating tank 50. An inlet 71 communicating with the drain hole 521 is formed at the upper end of the central drain cover 70, and one end of the main drain hose 80 is coupled to communicate with the inside of the central drain cover 70. In addition, a sealing member 72 is installed between the inlet portion 71 of the central drain cover 70 and the shaft flange 522 installed at the bottom of the rotating tub 50 to allow the rotating shaft 43 to penetrate therethrough. In the dehydration stroke, the shaft flange 522 is rotated while rubbing against the sealing member 72 to prevent leakage of the wash water between the shaft flange 522 and the inlet portion 71 of the central drain cover 70.

Further, at one end of the main drain hose 80, a sub drain hose 82 whose tip portion communicates with the water tank 20 is branched. One end of the sub-drain hose 82 is in communication with the inside through the bottom of the water tank 20, the other end is in communication with the main drain hose 80 of the lower side of the drain valve (81). The sub-drain hose 82 is for discharging the washing water discharged to the outside of the rotating tub 50 during the dehydration stroke of the washing machine to the outside of the housing 10.

Next will be described the operation of the washing machine according to the present invention configured as described above.

First, after opening the washing machine lid 13 and putting the laundry into the rotating tank 50 and operating the washing machine through a control unit (not shown), according to the amount of laundry, an appropriate amount of detergent and the detergent contained in the detergent dissolving device 14 Washing water is supplied into the rotating tub (50). At this time, since the drain valve 81 of the main drain hose 80 remains closed, and the dewatering hole 511 is locally drilled only at the upper end of the rotating tank 50, the washing water is shown in FIG. As described above, only the main drain valve 80 upstream and the central drain cover 70 and the rotating tank 50 are filled.

Subsequently, when a suitable amount of washing water is supplied into the rotating tub 50, power is applied to the motor 41 to generate power, whereby the pulsator 90 is reversed by the rotating shaft 43 of the clutch 42. Rotating water flows by rotation. Washing and rinsing is performed while the laundry is rubbed with the inner wall of the pulsator 90 and the rotating tank 50 by the washing water flow. Since the washing and rinsing administration is performed in a state in which only the washing water is filled in the rotating tank 50, the washing water and the amount of detergent are significantly reduced.

After the rinsing stroke is completed, the drain valve 81 is opened to operate the washing water in the rotary tub 50 through the drain hole 521, the central drain cover 70, and the main drain hose 80. ) It is discharged to the outside.

In the dehydration operation, the power is simultaneously transmitted to the rotating tank 50 and the pulsator 90 by the clutch 42, so that they rotate at a high speed in one direction, thereby dehydrating the laundry. That is, as shown in Figure 6, the water absorbed in the laundry due to the high-speed rotation of the rotating tub 50 is partially induced by the centrifugal force through the wall of the rotating tub 50 and the other part through the guide hole 514 As it flows into the space 515, it easily rises to the upper side along the rising ducts 512 and 513, and is discharged into the water tank 20 through a plurality of dehydration holes 511 formed adjacent to the lower end of the balancer 60. The water dewatered through this path flows down to the bottom surface of the water tank 20 and is discharged to the outside of the housing 10 through the sub drain valve 82. At this time, the pair of ascending flow paths 512 provided on the inner wall surface of the rotating tank 50 protrudes radially convexly from the inner wall of the cylindrical body 51 and extends in the vertical length direction, so that the water escapes from the laundry. This leads to the upper side of the rotating tank 50 is made smoothly dehydration. In addition, since the rising induction road 512 is covered through the induction furnace cover 513, water guided to the upper end side of the rotating tub 50 is prevented from coming into contact with the laundry, thereby making it easier to raise the water.

As such, since the washing machine is operated in a state in which only the required amount of washing water is supplied to the inside of the rotary tub 50 during washing and rinsing, water used for washing and rinsing is reduced, and power consumption is reduced due to the reduction of water supply time. In addition, environmental pollution by synthetic detergents can be prevented. In fact, the inventors of the laundry experiment through the washing machine was found that the water used is reduced by about 25%.

As described in detail above, according to the washing machine according to the present invention, since the dewatering hole is locally drilled to be spaced apart at a predetermined distance from the upper end of the rotating tank adjacent to the balancer and the rising duct is symmetrically provided on the inner wall of the rotating tank, washing and rinsing are performed. During the administration, the wash water is stored only inside the rotating tank where the actual laundry is stored, and during the dehydration administration, the washing water is easily discharged through the rising duct and the dehydration hole formed at the top, so that the amount of washing water is greatly reduced and detergent consumption There is also an advantage that can reduce the environmental pollution caused by domestic wastewater.
