In addition, the drain hose 7 is installed below the dehydration induction tank 2 to discharge the rinsing water and the washing water to the outside.

The washing tank 3 is composed of a horizontal bottom wall 33 and a vertical cylindrical wall 31, and the upper diameter of the vertical cylindrical wall 31 is made larger than its lower diameter to form a tapered shape. A balance ring 8 is provided at an upper portion of the vertical cylindrical wall 31, and a plurality of dehydration holes 5 are formed at the lower portion of the balance ring 8. An intermediate bottom plate 80 is provided between the horizontal bottom wall 33 and the stirring blade 4, and an inlet port 81 is formed in the middle of the intermediate bottom plate 80, and penetrates the suction port 81. To extend the drive shaft 45 of the stator blade 4.

The stirring blade 4 is provided with a plurality of vanes 43, that is, an impeller on its lower surface. Each vane 43 is formed in a radial straight line whose height varies from the center to the periphery. That is, the center of the stirring blade 4 is the highest and the edge is made the lowest. Thus, the washing water stored in the lower portion of the intermediate bottom wall 80 is pulled up through the suction port 81 so as to be discharged outward along the vanes 43.

The upflow induction pipe 70 extends from the upper surface of the intermediate bottom plate 80 in the washing tank 3 to the upper open end of the washing tank 3. As shown in FIG. 2, the upflow induction pipe 70 has a body whose cross section is formed in an angle shape, and the body 71 has a plate formed in parallel along the wall with a predetermined interval with respect to the inner wall of the washing tank 3 ( 71P), and a pair of side plates 71S extended from the plate 71P to the vertical cylindrical wall 33 is provided. A passage 76 is formed by the plate 71P and the side plate 71S to be used as an upward flow passage.

In addition, the upward flow guide pipe 70 discharges the pressure water increased through the inlet 72 and the passage 76 formed at the lower end of the body 71 to receive the pressure water discharged from the outside of the vane 43. The first discharge port 75 formed on the upper end of the body 71 and the second discharge port 76 formed to some extent below the first discharge port. The second discharge port 76 includes a detachable filter 77 and filters lint in the pressure water. Further, the first discharge port 75 is formed so that the pressure water passing through the passage 76 is directed toward the center of the washing tub 3. In other words, the portion of the balance ring 8 in contact with the lower portion is formed with a smooth curved corner, so that the pressure water rising through the passage 76 of the body 71 can be discharged more smoothly. In the present application, two upflow induction pipes 70 were installed at positions facing each other.

Downflow induction pipe 90 is installed to extend to the bottom of the balance ring 8 from the predetermined distance away from the intermediate bottom plate (80). As shown in FIG. 3, the downflow induction pipe 90 has a substantially arc-shaped body whose cross section will be described later. It is provided at regular intervals, and forms the passage 96 which consists of this body 91 and the side plate 71S of the upflow induction pipe 70, and uses it as a downward flow passage.

In addition, the downflow induction pipe 90 has a plurality of flow holes 92 in the body 91 to receive the washing water toward the vertical cylindrical wall 31 of the washing tank 3 by the stirring of the stirring blade (4). The outlet 95 is formed at the bottom of the body 91 to form and guide the washing water descending through the passage 96 to the lower portion of the intermediate bottom plate 80.

At this time, the upper portion of the body 91, that is, the portion formed toward the balance ring 8 flow hole 92 is separated from the laundry to wash water introduced into the passage 96 through the flow hole 92 washing tank ( Proceed to the dehydration hole (5) above the 3). Moreover, the ribs 97 are formed in the passages 96 formed between the body 91 and the vertical cylindrical force 3 so as to extend vertically. This prevents the wash water introduced into the passage 96 through the flow hole 92 of the right side (or the left side) of FIG. 3 from being discharged back to the flow hole 92 of the left side (or the right side).

In addition, the front surface 91A of the body 91, that is, the portion facing the center of the washing tub 3 is formed to be convex toward the vertical cylindrical wall 31 with a radius of curvature smaller than the radius of curvature of the washing tub 3 and the laundry. Reduced resistance. Furthermore, both side surfaces 91B and 91C of the body 91 are formed in a convex shape toward the center of the washing tub 3 so that more washing water may flow through the flow hole 92 when the washing tub 3 is rotated. It was easily introduced into. Moreover, the upper width of the body 91 was made smaller than the lower width thereof, so as not to disturb the laundry rotating with the washing water while mainly rising toward the upper portion of the washing tub 3. In the present application, two downflow induction pipes 90 were installed at intermediate positions of the two upflow induction pipes 70 respectively.

The intermediate bottom plate 80 is concave so that the stirring blade 4 is rotatable at the top thereof, as shown in FIG. 4, and is spaced a predetermined distance from the horizontal bottom wall 33 of the washing tub 3 to form a vertical cylindrical wall 31. Are fitted to fit underneath. Between the horizontal bottom wall 33 and the intermediate bottom plate 80 is formed as a reservoir (85) for holding the wash water introduced from the down stream induction pipe (90). A suction port 81 is formed in the center portion of the intermediate bottom plate 80 to be used to lift the washing water of the water storage tank 85 to the vane 43 rotatably installed on the upper side of the intermediate bottom plate 80.

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 wash the wash water between the lower surface of the stirring blade 4 and the upper surface of the intermediate bottom plate 80. In any direction of rotation, the washing water is discharged radially outward. 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 stage, some of the laundry which is not wet is placed on the surface of the washing water, but all the laundry is quickly submerged in water due to the pressure water such as the waterfall water pouring into the center of the washing tank 3 through the pair of first discharge ports 75. . 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 wash water in the washing tank 3 is formed on the surface 91B of the downflow induction pipe 90 opposite to the rotation direction as the washing tank 3 rotates in one direction, for example, from left to right in FIG. It enters the passage 96 through the flow hole 92.

Thereafter, if the washing tub 3 rotates in the direction opposite to the above direction, that is, from right to left in FIG. 4, the washing water passes through the flow hole 92 of the surface 91C of the downflow induction pipe 90. Flows into). The down stream descending 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.
