When the water supply is completed, the motor 34 is turned on and off to repeat the driving and stopping of the washing shaft 31 periodically (for example, repeating 13 times with one cycle of 0.5 second stop), and the quantity monitoring sensor in movement ( The water supply valve 4 is opened by counting the number of times the permanent magnet 71 passes through the induction coil 72 by 70. Subsequently, the microprocessor calculates that the quantity of the quantity detecting sensor 70 is large and small by comparing the number counted by the quantity detecting sensor 70 with the basic data input to the RAM of the microcomputer in advance. The rotation speed of the washing shaft 31 corresponding to this is determined, and the solenoid 61 of the elevating mechanism 60 is turned on.

When the solenoid 61 is turned on in this way, the connecting lever 64 connected to the plunger 61a is pulled downward so that the operating lever 63 rotates counterclockwise about the shaft 63 'so that the transmission member 65 is rotated. As the pushing member 65 pushes up the space 66, the driving gear 51 rises to overcome the force of the spring 67, and the driving gear 51 meshes with the intermediate gear 52. Subsequently, as the motor 34 is turned on to rotate the washing shaft 31, the driving gear 51 rotates together with the washing shaft 31, the intermediate gear 52 and the driven gear 53 rotate, and the feeding screw ( 41 is rotated, the laundry press combined auto balancer 20 is moved downward, and the amount sensor 70 continues to check the rotation speed of the laundry shaft 31 to reach the rotation speed of the laundry shaft 31 determined previously. When the solenoid 61 is turned off, the plunger 61a thereof is drawn upward, the connecting lever 64 moves upward, and the operating lever 63 rotates clockwise so that the drive gear 51 and the spacer ( 66 and the transmission member 65 is moved downward by the resilience of the spring 67, the drive gear 51 and the intermediate gear 52 is separated.

Therefore, the intermediate gear 52 and the driven gear 53 stop and the feeding screw 41 stops, whereby the position of the laundry pressing and auto balancer 20 is processed. When the absorption is completed, the water level sensor 73 detects and turns off the water supply valve 6 and repeats the rotation of the stirring means 10 forward, stops, and reverses 3.2 seconds by one cycle by the driving force of the motor 34. do.

In the case where the above washing operation is repeated one or more times, after the one time operation is finished, the washing shaft 31 is briefly rotated forward and backward (for example, the forward and reverse rotation is performed for 1 second intervals for 30 seconds). Prevents the washing of the laundry, and after the previous operation is repeated for a predetermined number of times, the drain valve (7) is opened and the water supply valve (6) is opened for a predetermined time to remove the foam generated during washing, after which The valve 6 is turned off and drained for a predetermined time 20 to 30 seconds.

In this way, when the washing is finished for a predetermined time, the rinsing is performed, the rinsing is performed by dehydration, water supply, washing for a short time, and when washing during rinsing, the previously determined quantity, forward and reverse rotation cycles are used.

After rinsing, the power of the motor 34 is connected to the dehydration tank 2 so that the dehydration tank 2 is rotated at high speed and dehydrated by centrifugal force.

After all the above processes are finished, the laundry pressing auto balancer 20 is moved upward to the uppermost level in the reverse direction to raise the limit switch supporter 75 so that the limit switch 76 is connected and the pre-washing process is terminated. To be prepared.

Ah, the washing operation of the washing apparatus according to the present invention will be described in more detail as follows.

According to the amount of laundry contained in the dehydration tank (2) during washing, the laundry pressing auto balancer (20) moves downward to stop the pressing plate (2) in contact with the laundry (2). When 10 rotates, the laundry is agitated by the stirring means 10 in a narrow washing space formed by the inner wall of the dehydration tank 1 and the stirring means 10 and the pressing plate 22. In this case, since the pressing plate 22 is formed of the uneven surface 22 'having the recessed portion 22a and the protrusion 22b, the pressing plate 22 hits the uneven surface 22' while stirring the laundry to provide a strong compressive force. Since the roller 14 rotates together with the stirring means 10 in the rotating disc 11 of the stirring means 10, the laundry sandwiched between the pressing plate 22 and the rotating disc 11 is a pressing plate. Cast and beat by the uneven surface 22 'of the 22 and the roller 14 of the rotating disk 11 It said, under the action grated addition, stirring is rolled As.

As such, the laundry machine of the present invention washes while performing a complex washing exercise such as kneading, tapping, rubbing and rolling motions. The washing effect is excellent compared to any conventional washing machine and is narrow according to the amount of laundry. Since the laundry is washed in the laundry space, the amount of washing water can be reduced.

In addition, the laundry machine of the present invention drives the washing shaft 31 by the driving force of the motor 34, by the power relay means 50 and the lifting mechanism 60 to interrupt the driving force of the motor 34, the laundry pressing combined auto The balancer 20 has an economic advantage because the up and down reciprocating movement is performed efficiently, there is an advantage that the power supply is easy.
