54) is provided with an engagement receiving part (55) consisting of a groove that elastically engages with the above-mentioned engagement part (53), and the filter frame <51
) into the recess (41) and remove the filter frame (51).
The filter (49) is attached by fitting the rectangular frames on both sides to the both side walls (54), and further engaging the engaging portion (53) and the engaging receiving portion (55). Also, the filter frame (51) is prevented from falling on the both side walls (54).
A pedestal (56) for holding the sea urchin in one piece is integrally formed.

Now, take the filter (49) into the recess (41).
When the filter frame (51) is removed, the front side of the filter frame (51) protrudes from the recess (41) as shown in Figure 4, and by holding this part and pulling it toward you, the filter (49) can be easily removed from the recess (41). It can be removed from the 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 lip formed on the outer periphery of the rotor blade (7) in a size (A) or hanging down, which increases the pressure in the pump chamber (21) during rotation, and increases the pressure in the opening (6). Reduces the amount of water that leaks into the tank through gaps. (58) is an annular outer tank cover placed over the upper part of the outer tank (1).

To explain the operation, first, when washing or rinsing, the rotor blade (7)
When the is rotated, water between the outer tank (1) and the dehydration tank (2) is drained from the through hole (22>) to the pump chamber (as shown by the arrow in Fig. 21).Most of the sucked water is quickly sent out to the open part (23) along the straight part (24)<24) no matter which direction the rotor blade (7) rotates. , from which the discharge passageway (28)
from the downward discharge r+ (4g) through the discharge pipe (33> and passage (47)) to the lint filter (4g).
9) and is discharged approximately vertically into the dehydration tank (2).

In this way, only a small amount of water circulates in the pump chamber (21) (7) and flows out from the opening (6) into the dehydration tank (2), and most of the water flows through the dehydration tank. Since they overlap perpendicularly to the rotating water flow in (2), the water flow becomes #i coarse, promoting the upper and lower rotation of the laundry, improving the washing rate, and suppressing uneven washing. In particular, since the discharged water does not spread and falls directly below, it hits the floating laundry and sinks it under the water surface, further improving the washing efficiency.

Use a lint filter (49) to remove lint, etc. contained in the water.
can be reliably collected. At this time, the water coming out of the discharge port (48) flows 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 is some thread waste that cannot be caught at the tip of the net (50), as shown in Figure 1, place the tip of the net (50) a dimension (B) above the washing water surface (L) (at high water level). When the washing water flow or laundry hits the net (50), the vibrations at this time can push the lint caught by the net (50) to the tip of the toke.Cleaning the filter (49) is done by cleaning the filter (49). All you have to do is remove the frame (51) from the recess (41) and turn over the net (50).When installing the filter (49), the filter frame (51) is symmetrical, so be careful about the direction and place it in the recess. (41) and is easy to use. Also, the net (50) can be used even if it is turned upside down.

When the lint filter (49) is dehydrated with a kneeler, the filter frame (51) tends to become even more flat due to the centrifugal force, which means that the lateral dimension of the filter frame (51) expands, causing the retaining part (51) to become even more flat. 53) more reliably engages with the engagement receiving portion <55), so there is no fear of it coming off due to centrifugal force.

In addition, there is a through hole (59) in the filter frame (51) as shown in Figure 7.
), even if the net (50) becomes clogged with thread waste, the water coming out of the outlet (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 laundry gets entangled with the filter (49) during washing and rinsing and is pulled circumferentially to remove it.
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) is subjected to the elastic force of the elastic piece (52) in the direction from the inside to the outside of the tank, but cannot be allowed to act in the circumferential direction. It will not come off the cylinder even if it is pulled.

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.
