) forms a bent part (36) that is gently bent inward from the middle lower part fitted in the vertical groove (32) to the upper part completely inserted into the retaining ring (35) closer to the inside of the tank, This bent portion (36) is allowed to partially protrude into the tank, thereby producing the action of a washing plate and reducing resistance to discharge pressure.

Here, the balance ring (34) encloses a liquid (37) that acts as a balunner, and is attached to the upper end of the dehydration tank (2) with a screw (38).
This balance ring <34) has upper and lower annular groove bodies (39
) (40) by welding the opening edges thereof. A recess (41) is formed in the inner wall of the balance ring (34), which is completely open on the lower side and basically open on the upper side. A communication part (42) that bridges the opposing side walls of the recess (41) is provided in the upper part on the back side of this recess (41), that is, in the two-side recess groove body (39). The connecting portion (42) forms the retaining ring (35>).

Then, attach the screw (43) to the top of the balance ring (34).
The upper end of the discharge pipe (33) is held down by the hanging piece (45) of the cover (44) attached to the cover (44), so that the lower end of the discharge pipe (33) does not come out of the discharge path (28).

And a guide 46) that changes its direction downward in cooperation with the communication part (42) bridges the opposing side walls at the upper end of the front side of the recess (41), just like the communication part (42). It is set up as follows.

The discharge waterway of the pump chamber (21) includes a discharge passage (28) formed on the outer bottom surface of the dehydration tank, a discharge pipe (33), as described above.
In addition, the cover (44), communication part (42), and guide (46)
) is formed by a passageway (47>), which terminates in a downwardly directed outlet (48).

(49) is a lint filter that is removably fitted into the front side of the recess (41) of the balance ring (34), and is located directly below the discharge port (48) to receive the discharged water. Drop it into the tank from above. This lint filter (4
9) consists of a conical net (50) and a synthetic resin filter frame 51 to which the net (50) is attached, as shown in Fig. 6, and both sides of the filter frame (51) are formed into a square frame shape. The outer side thereof is an elastic piece (52) that is thinner and has elasticity than the frame body;
2) is provided with an engaging portion (53) consisting of a protrusion.

On the other hand, both opposite sides 5f of the upper front side in the recess (41)
The fi (54) is provided with an engagement receiving part (55) consisting of a groove that elastically engages with the engagement part (53), and the filter frame (51) is inserted into the recess (41). The filter (49) is pushed in to fit the square frames on both sides of the filter frame (51) into both side walls (54), and further engages the engagement portion (53> and the engagement receiving portion (55)). Further, a pedestal (56) for holding the filter frame (51) to prevent it from falling is integrally formed on both side walls (54).

When the filter (49) is installed in the recess (41), the front side of the filter frame (51) protrudes from the recess (41>) as shown in Figure 4, so hold this part. You can easily remove the filter (49) by pulling it toward you (
41>. The pedestal (56) also protrudes from the recess (41) and serves as a guide when inserting the filter frame (51) into the recess (41).

57) is a rib formed on the outer periphery of the rotor blade (7) so as to hang down by the dimension (A), which increases the pressure in the pump chamber (21) during rotation, and allows the tank to flow through the opening 6). Decrease the amount of water that flows inside [7]. (58) is the outer tank (
1) is an annular outer tank cover placed over the top of the tank.

To explain the operation, first of all, when washing or rinsing, the rotary blade is turned 7)
When rotates, due to the pumping action of the back blade (9〉・ ),
Water between the outer tank (1) and the dewatering tank (2) is sucked into the pump chamber (21) through the through holes (22) as indicated by the arrows in FIG.

Most of the sucked water is quickly sent out along the straight portions (24) (24) to the open portion (23) regardless of which direction the rotor blade (7> rotates), and from there to the discharge path. 28), passes through the discharge pipe (33) and passageway 47), and passes through the downward discharge port (4B) to the lint filter (49).
It is discharged approximately vertically into the dehydration tank (2) through the .

In this way, since less water circulates within the pump chamber (21), less water comes out from the opening (6) into the dehydration tank (2), and most of the water is inside the dehydration tank (2). Since the water flow overlaps perpendicularly to the rotating water flow of the washing machine, the water flow becomes complicated, and it is possible to promote the vertical rotation of the laundry, improve the washing efficiency, and suppress uneven washing.In particular, the discharged water does not spread. As it falls directly below without any movement, hit the laundry that is trying to float,
It acts as if it is submerged under the water surface, further improving cleaning efficiency.

Use a lint filter (49) to remove lint, etc. contained in the water.
will be reliably collected. At this time, the water coming out of the discharge port (48) flows down toward the tip of the net (50), so lint accumulates from the tip of the net (50), and when cleaning the filter (49), Thread waste can be easily removed from (50). Even if there was some thread waste that could not be caught at the tip of the net 1 (50),
As shown in the diagram, if the tip of the net (50) is lowered by the dimension (B) below the washing water level (L) (at a high water level), the washing water flow and laundry will hit the net (50), and the vibrations at this time will You can push the thread waste caught by Otsudo (50) to its tip. To clean the filter (49), remove the filter frame 51) from the recess (41) and remove it from the net (50).
Just turn it over. When installing the filter (49), since the filter frame (51) is symmetrical, it can be easily inserted into the recess (41) without worrying about the direction, making it easy to use.

Moreover, the Otsudo (50) can be used even if it is turned upside down.

By the way, during dehydration, the lint filter (49) is subjected to centrifugal force and the filter frame (51) tends to become even more flat, that is, the lateral dimension of the filter frame (51) expands, and the engaging portion (53) Since it engages with the engagement receiving part (55) more reliably, there is no fear of it coming off due to centrifugal force.

In addition, the filter frame (51) has a through hole (59) as shown in Figure 7.
), even if the net (50) becomes clogged with thread waste, the water coming out of the discharge port (48) will flow through this hole (
59) into the dehydration tank (2), and the filter frame (5
1) There is no unsightly overflowing from above, thereby preventing thread waste from adhering to the fitting portion between the engagement receiving portion (55) and the engagement portion (53).

It is also possible that the laundry gets entangled with the filter (49) during washing or rinsing and can be removed by pulling it in the circumferential direction.
Since the portions of the filter frame (51) connected to the elastic pieces (52) on both sides are thick, the rigidity in the circumferential direction is large. That is, the filter (49) allows the elastic force of the elastic piece (52) to act in the direction of the inside and outside of the tank, but does not allow the elastic force to act in the circumferential direction. It doesn't come off easily.

In addition, when cleaning the discharge waterway in case of clogging, etc., remove the cover (44) to expose the passageway (47) and clean the discharge pipe (
33) can also be taken out for easy cleaning.

Can be done.

(G) Effects of the Invention According to the present invention, in addition to operating the lint filter from inside the tank, the pedestal also serves as a guide.
The ease of attaching and detaching the filter has been greatly improved, and the installation of the lint filter has become extremely stable. Therefore, it is possible to provide a dehydrating washing machine that is easy to use and has a stable structure.
