Hereinafter, the operation of the present invention configured as described above will be described.
First, cloth m is put into the drum 76, detergent is put into the detergent box 96 and the door 59 is closed, and then a process and time such as washing and rinsing are selected. Is turned on, and a predetermined amount of washing water w is sent.

  The washing water w that has passed through the water supply valve 94 passes through the water supply hose 95 and flows into the detergent box 96, and then is mixed with detergent in the detergent box 96 and passes through the detergent box 96. Guided behind the drive shaft 86 through a water supply bellows tube 97.

  The washing water w mixed with the detergent guided to the rear of the drive shaft 86 is guided by the water supply passage 87 of the drive shaft 86 and passes through the drive shaft 86, and enters the water supply passage 85 of the spider 80. It is guided and passes through the spider 80, passes through the water supply passage 79 of the drum 76, and flows into the water supply passage 91 of the lifter 90.

  The washing water w including the detergent that has flowed into the water supply flow path 91 of the lifter 90 is sprayed toward the inside of the drum 76 through the spray nozzle 92 in order to wet the cloth m, and directly contacts the cloth m.

  Thereafter, when the motor 70 is turned on and the drive shaft 86 rotates, the spider 80 and the drum 76 rotate together with the drive shaft 86. In addition, after the lifter 90 lifts the cloth m onto the inner upper part of the drum 76, the lifter 90 falls from the inner upper part of the drum 76 by its own weight and swings, so that the contaminants of the cloth m fall.

  On the other hand, in the washing machine, when the drum 76 rotates as described above, if the water supply valve 94 is turned on for a predetermined time, the washing water w that has passed through the water supply valve 94 is changed to the water supply hose 95 and the detergent box. 96, water supply bellows pipe 97, water supply flow path 87 of drive shaft 86, water supply flow path 85 of spider 90, water supply flow path 79 of drum 76 and water supply flow path 91 of lifter 90 pass in that order and pass through the injection nozzle 92. While being strongly jetted toward the inside of the drum 74, the cloth m collides more strongly and the cleaning power of the cloth m is improved.

  In the washing machine, after the washing process is performed for a predetermined time, when the motor 70 is turned off and the drain pump 66 is driven for a predetermined time, the contaminated washing water w in the tub 60 is discharged. The drainage bellows pipe 65, the drainage pump 66, and the drainage hose 67 are sequentially discharged to the outside of the washing machine.

Thereafter, the washing machine performs a rinsing process for rinsing the foam of the fabric m.
During the rinsing process, the water supply valve 94 is turned on for a predetermined time to pass a predetermined amount of washing water w. In addition, the washing water w that has passed through the water supply valve 94 passes through the water supply hose 95 and flows into the detergent box 96 and passes through the detergent box 96 without being mixed with the detergent, as in the washing process. Then, it is guided behind the drive shaft 86 through the water supply bellows tube 97.

  The washing water guided to the rear of the drive shaft 86 is sprayed toward the inside of the drum 76 and is brought into direct contact with the cloth m in order to wet the cloth m, as in the case of water supply before the washing stroke. .

  Thereafter, when the motor 70 is turned on and the drive shaft 86 rotates, the lifter 90 rinses the foam of the cloth m while swinging the cloth m as in the washing process.

  In the washing machine, when the water supply valve 94 is turned on for a predetermined time during the rinsing process, that is, while the drum 76 is rotating, the washing water w that has passed through the water supply valve 94 is the same as that during the washing process. In addition, by strongly injecting toward the inside of the drum 74, the cloth m collides more strongly and the rinsing force of the cloth m is improved.

  Thereafter, after the rinsing process has been performed for a predetermined time, the washing machine w turns off the motor 70 and the drain pump 66 is driven. 65, the drainage pump 66 and the drainage hose 67 are passed through in order and discharged to the outside of the washing machine.
