The washing water w including the detergent flowing into the water supply passage 91 of the lifter 90 is sprayed toward the inside of the drum 76 through the spray nozzle 92 and directly to the cloth m. It will be wetted by contact.

Then, when the motor 70 is turned on and the drive shaft 86 is rotated, the spider 80 and the drum 76 are rotated together with the drive shaft 86, and the lift 90 m) is pumped into the upper portion of the drum 76, the foam (m) is flowed while falling by its own weight at the inner upper position of the drum 76, so that the contamination on the fabric falls as the flow proceeds do.

On the other hand, in the washing machine, when the water supply valve 94 is turned on for a predetermined time while the drum 76 is rotated as described above, the washing water w passing through the water supply valve 94 is the water supply hose 95. And a detergent container 96, a water supply bellows pipe 97, a water supply flow path 87 of the drive shaft 86, a water supply flow path 85 of the spider 90, and a water supply flow path 79 of the drum 76. ) Passes through the water supply passage 91 of the lifter 90, and is strongly injected toward the inside of the drum 74 while passing through the injection nozzle 92, and strikes the fabric m more strongly. Will increase the cleaning power of.

In the washing machine, if the motor 70 is turned off after the washing stroke is performed for a predetermined time, and the drain pump 66 is driven for a predetermined time, the contaminated washing water w in the tub 60 is It passes through the drain bellows pipe 65, the drain pump 66, and the drain hose 67 in order to drain the outside of the washing machine.

The washing machine then carries out a rinse stroke to rinse the foam in the fabric m.

In the rinsing stroke, the water supply valve 94 is turned on for a predetermined time and passes a predetermined amount of the washing water w, and the washing water w passing through the water supply valve 94 is the same as in the washing stroke. Passes through the water supply hose (95) into the detergent container (96), passes through the detergent container (96) without mixing with the detergent, and through the water supply bellows pipe (97) to the rear of the drive shaft (86) You are guided.

The washing water guided to the rear of the drive shaft 86 is sprayed toward the inside of the drum 76, as in the case of water supply before the washing stroke, and wetted in direct contact with the fabric (m).

Then, when the motor 70 is turned on and the drive shaft 86 is rotated, the lifter 90 flows the fabric m as in the washing stroke, and the fabric flows into the fabric as the flow proceeds. The foam will rinse off.

In the washing machine, when the water supply valve 94 is turned on for a predetermined time during the rinsing stroke, that is, while the drum is being rotated, the washing water w passing through the water supply valve 94 is the washing stroke. As shown, it is injected strongly toward the inside of the drum (74), hitting the cloth (m) more strongly to increase the rinsing force of the cloth.

Then, the washing machine is the motor 70 is turned off after the rinsing stroke as described above for a predetermined time, when the drain pump 66 is driven, the washing water (w) containing foam is drained bellows pipe (65) ) And the drain pump 66 and the drain hose 67 are sequentially drained to the outside of the washing machine.

The bearing holder 120 is formed to be hollow so that the drive shaft 86 penetrates and communicates with the inlet 87a of the water supply passage 87, and the guide bellows tube 106 ′ is connected to one side of the bearing holder 120. do.

In the washing machine according to the present embodiment, when the circulation pump 104 'is driven, the washing water w inside the tub 60 is drained to the circulation pump 104' through the drainage bellows 102 '. And pumped into the circulation bellows pipe which is the guide flow path 106 'by the circulation pump 104'.

The wash water w pumped into the circulation bellows pipe 106 'is pumped between the plurality of bearings 112 and 116, and the water supply passage 87 of the drive shaft 86 between the plurality of bearings 112 and 116. Flows into the inlet 87a.

The washing water w introduced into the inlet 87a of the water supply passage 87 of the drive shaft 86 is, as in the second embodiment of the present invention, the water supply passage 87 of the drive shaft 86 and the spider. After passing through the water supply passage 85 of 90, the water supply passage 79 of the drum 76, and the water supply passage 91 of the lifter 90, the drum ( Sprayed / circulated toward the inside of 76).

In addition, this invention is not limited to said embodiment, It is also possible for the water supply apparatus 93 of 1st Embodiment of this invention to supply wash water w between the some bearing 112,116 of 3rd Embodiment of this invention. And, the drainage device 64 is branched from the circulation device 100, it is of course possible to drain the wash water passing through a portion of the circulation device 100 to the outside of the washing machine.

In the washing machine according to the present invention configured as described above, since the washing water passes through the drive shaft, the spider, the drum, and the lifter in turn, the water is sprayed from the lifter to the inside of the drum. This has the advantage of improving performance.

In addition, the washing machine according to the present invention has the advantage that the washing water is sprayed toward the center side of the drum from the inner circumferential surface side of the drum, so that the non-injection area in which the washing water is not sprayed is minimized, and the washing water is evenly soaked in the cloth. .

In addition, the washing machine according to the present invention has the advantage that the washing water is not pumped up to the upper height of the drum, the pump is pumped up to the height of the center side of the drum, so that the pumped height and the flow path resistance are minimized, so that a large amount of wash water can be quickly circulated. have.
