In addition, a flow hole 89 is formed on the outer circumference of the intermediate bottom plate 80, and the outlet 97 of the downflow guide pipe is coupled to the flow hole 89. As a result, the downward flow exiting the outlet 97 flows into the reservoir 85 existing under the intermediate bottom plate 80 via the flow hole 89. On the other hand, an induction furnace 87 for guiding the washing water on the upper portion of the intermediate bottom plate 80 to the inlet 72 on the outer circumference of the intermediate bottom plate 80 in contact with the inlet 72 of the upward flow induction pipe 70. ) Was formed to more easily guide the washing water to the inlet (72).

The washing machine of the present invention configured as described above acts as follows.

The laundry is put in a washing tank 3 having an appropriate amount of washing water, and firstly, the stirring blade 4 is reversed according to the power transmitted from the driving unit 6. At this time, the washing water of the upper portion of the stirring blade 4 falls through the plurality of holes (not shown) passing through the stirring blade 4 to the lower portion of the stirring blade 4. A plurality of vanes 43 formed on the lower surface of the stirring blade 4 to serve as an impeller rotate with the driving of the stirring blade 4. Since the vanes 43 are formed in a straight line, the wash water between the lower surface of the stirring blade 4 and the upper surface of the intermediate bottom plate 80 is radially outside the washing water in any direction of the stirring blade 4. To discharge. The wash water struck by the bain 43 is forcibly sent to each inlet 72 of the upflow induction pipe 70. The pressure water passing through the inlet 72 rises along the passage 76 of the body 71 by the impeller operation.

In the wash water that has advanced along this passage 76, the lint fed with water is heavier than the water, the water is directed to the first outlet 75, and the lint is directed to the second outlet 76 and the lint is It is filtered by the filter 77. The pressure water passing through each of the first discharge ports 75 is discharged toward the center of the washing tank 3, and a pair of first discharge ports 75 are formed along the upper part of the washing tank 3 so as to face each other. It falls into the washing tank 3 vigorously like a waterfall.

In the initial washing stage, some of the laundry that is not wet is placed on the surface of the washing water, but the entire laundry is quickly submerged by water, such as waterfall water, which is poured into the center of the washing tank 3 through the pair of first discharge ports 75. do. Thereafter, the stirring blade 4 is reversed in the main washing step, and the laundry under the washing tank 3 soars to the upper center of the washing water. The pressure water pouring down from all the first outlets 75 is locked to the laundry to be raised again to the lower wash surface, and the laundry is pounded to wash.

On the other hand, in the process in which the washing tank 3 is changed from the forward rotation direction to the reverse rotation direction, the pressure water pouring into the middle portion of the washing tank 3 is gradually poured to the upper edge of the washing tank 3, that is, the balance ring 8 side. The waterfall to this edge is to push the laundry below the wash surface, obstructing the course of the laundry to rise along the inclined vertical cylinder (31).

The washing water in the washing tank 3 is a flow hole formed in the first down stream induction pipe 90R opposite to the rotating direction as the washing tank 3 rotates in one direction, for example, from left to right in FIG. It enters the passage 96 through 92.

Thereafter, if the washing tub 3 rotates in the opposite direction to the above direction, that is, from right to left in FIG. 2, washing water flows into the passage 96 through the flow hole 92 of the second downflow guide pipe 90L. Washing water is mainly hit by the side plate (71S) of the upflow induction pipe 70 is lowered along the passage 96 is introduced into the reservoir 85 through the flow hole 89 of the intermediate bottom plate (80).

Rotation of the vanes 43 pulls the wash water stored in the water storage tank 85 to the upper side of the intermediate bottom plate 80 through the suction port 81 of the intermediate bottom plate 80. The washing water sucked into the vane 43 through the suction port 81 flows in a passage formed between the stirring blade 4 and the intermediate bottom plate 80. The incoming washing water is discharged radially outward of the vanes by the rotating vanes 43 and is forcibly sent to the inlet 72 of the upflow induction pipe 70. In this way, it flows into the washing tank 3 through the upflow induction pipe 70, and then returns to the water storage tank 85 through the downflow induction pipe 90, the return washing water is again raised by the vanes 43. By repeating the circulation to the flow guide pipe 70, the fluff etc. in the washing tank 3 continue to filter through the filter 77 of the 2nd discharge port 76. As shown in FIG.

After the above washing process is completed, in the draining process, the washing water in the washing tank 3 is drained to the outside through the outlet 7A of the hose 7 installed below the stirring blade 4. At this time, lint or the like contained in the washing water in a very small amount is filtered by the filter 7C on the outlet 7A.

Then, during the dehydration process, when the washing tub 3 rotates in one direction, the washing water separated from the laundry rises along the inner surface of the vertical cylindrical wall 31 to exit the dehydration hole 5. Dehydration that strikes the inner surface of the dehydration induction tank 2 is lowered and drained to the outside through the outlet 7B of the hose 7.

The washing machine of the present invention operating as described above sends the laundry to be raised to the upper washing water surface reversed during the washing down to the washing water with the pressure water pouring down into the upstream induction pipe, and further, the laundry to be raised along the inclined washing tank. It can be descended into water. Furthermore, by repeatedly circulating the wash water containing lint and the like in the washing tank, the lint and the like are filtered out to reduce the amount of lint blocking the filter of the hose at the time of drainage or to prevent the dehydration hole in the upper part of the washing tank when dewatering. Thus, dehydration is smoothly discharged through the open dehydration hole, so that the dehydration time can be shortened to increase the dehydration efficiency.

In addition, the upstream induction pipe and the downflow induction pipe integrally configured to reduce the resistance to the laundry to increase the washing efficiency and at the same time has the effect of increasing the effective content of the washing in the washing tank.
