Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a dehydrating washing machine in which recycled water is forcibly circulated.

(b) Conventional technology This type of dehydrating washing machine is exemplified by Japanese Patent Application Laid-Open No. 52-131661.
Publication No. 〇The pump chamber is formed on the back side of the rotor blade by the back blade, a part of the thickness of the blade is cut out and a discharge waterway is formed from there by a groove, and this waterway is opened. 11 sides are closed with waterway covers. This water channel cover is either a road surface with respect to the bottom of the tank, or protrudes inward with respect to the peripheral side of the tank, and serves as a washing plate to scrub the laundry that is floating around.
0 However, this channel cover does not have the effect of scrubbing the laundry that is moving around, or presses the laundry from above to encourage the change of the laundry, and the cleaning effect is reduced in two directions -4a)-'j)-
rIt was not sufficient in terms of preventing uneven washing.

(c) Problems to be Solved by the Invention The present invention utilizes a discharge pipe, which is a waterway for discharge.
i'5111+ improves the effect and suppresses uneven movement to ``1-''.

(D) Means for Solving the Problems The present invention is provided with a discharge pipe disposed from the lower part of the tank to the upper part of the tank. This problem can be solved by providing a curved section with a gentle bend in the tank from the soil section to the soil section.

(Po) Function: The moving laundry is rubbed by the m1 curved part and pressed downward, encouraging the upper and lower turns, further improving the washing effect, and at the same time suppressing uneven washing. In addition, the bent portion of the discharge pipe is loose and does not significantly increase the resistance of the discharge waterway and reduce the amount of water discharged.

(f) To explain based on the example drawings, 1) is the outer tub of a fully automatic washing machine suspended from the machine frame, and the synthetic resin washing/drying tub (2)
) is installed inside, and bearing (3) and motor (4) are installed outside.
- It has a roughly hexagonal shape consisting of an arcuate wall and a flat wall, and the bottom and sides are bent inward from the bottom. ridge (5)
An opening (6) is formed at the center of the bottom.

(7) is attached to the rotating blade C1 rotor shaft (8) which is arranged with a small gap in the opening (6), and there are multiple back blades (9) on the back side. (10) is a large number of dehydration holes formed on the peripheral side wall of the dehydration tank (2), (1
1) are reinforcing ribs formed vertically and horizontally on the outer surface of the peripheral side wall of the dehydration tank (2), (12) are reinforcing radial ribs formed on the outer bottom surface of the dehydration tank (2), and (13) are The reinforcing concentric rib (14) also formed on the outer bottom surface is the third boss formed from the inside of the concentric rib (13).

(15) is a bolt to the dehydration tank drive shaft (16), <17>
The innermost rib (19) of the concentric rib (13) on the dehydration tank substrate fixed by the to/to (18) and the boss (]
4) and is connected to the dewatering tank (2) by tightening a screw <20) to the boss (14). Soshi-(
, the board (15) and the rig (19) are the back of the record.
A pump chamber (21) is constituted by a plurality of through holes (22) in the substrate (15) to suck water between the tank (1) and the dehydration tank (2).

Here, the rib (19) is not completely annular, but has a second shape.
As shown in the figure, it has an open part (23) that opens toward the corner where the raised part (5) is located, and the arcuate wall leading to this open part (23) is shaped like a square. Target line (24) (2
4), and furthermore, an expanding part (25) which expands from the straight part (24) (24) by external force is provided. Then, the open portion (23) becomes the discharge port of the pump chamber (21).

In addition, the expanded part (25) is located on the outer bottom surface of the dehydration tank (2), and a corner part (26) is opened on the outside.
It is connected to Part of this corner (26) is a waterway cover (
27), and a discharge channel 28 which communicates with the chamber (21) through an enlarged opening 25).
〉 Also, this 21-na part (26) can be used once by using the widening part (25) together with the raised part (5) as a passage for cutting out the mold when molding into one piece with the core.

The water channel cover (27) has a shape as shown in FIG. ) at both ends as shown in Figure 2-C.
31) (31) To be stopped.

In this way, the discharge waterway (28) is formed into a square tube shape with great strength without missing the circular shape of the opening (8), and the waterway area is further enlarged by the raised portion (5). .

(32) is an Xk groove formed in the circumferential wall of the dewatering tank (2) corresponding to part (26), and the opening at the end thereof is a part of the corner of the discharge channel (28). It communicates with the upper end of (26). (33) is a discharge pipe that is fitted into the vertical groove (32) in close contact with the vertical groove (32), and is made to have an approximately oblong cross section by blow molding, and its lower end opening is connected to the -F of the vertical groove (32). The end opening, that is, the one end of the discharge waterway (28), is fitted with W, and the upper end is inserted into the retaining ring (35) closer to the tank of the balance ring (34) containing the liquid balancer of the dehydration tank (2>). This discharge v (33) flows inward from the middle lower part, which is intertwined with the vertical groove (32), to the upper part, which is inserted into the retaining ring (35) of the tank internal tank. A bent part (36) is formed which is gently bent towards the tank, and this bent part (36) partially protrudes into the tank to create a washing plate effect and reduce resistance to the discharge pressure. .

(37) is attached to the Y-plane of the balance rig (34).
8) With the cover closed, lower the hanging moon (39) to 41 and 1.
This vertical piece (39) holds down the two-wheel opening of the discharge pipe (33) and prevents [11] between the lower ends of the discharge pipe (33) from coming off the discharge channel (28). (40) is a passage communicating with the −1 end opening of the discharge pipe (33), and the retaining ring
35) and force 2<-(37)), and the outlet (41) facing toward the direction faces into the dehydration tank (2).

(42) is attached to the sling (34) so that the neck can be removed freely.
・This is a lint filter with a conical shape (43) and a synthetic resin mounting frame (44), which receives water discharged from the downward outlet (41) from below and removes lint, etc. in the water. Collect the water and return it to the tank.

(45) 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 1 (21) during rotation, and increases the pressure in the tank from the gap in the opening (6). Reduces the amount of water flowing inside. (46) is an outer tank cover attached to the upper end of the outer tank (1).

To explain how it works, when the rotary blade (7) rotates during washing, the pumping action of the back blade a (9) causes the water to flow between the outside (1) and the dehydration tank (2). The water is sucked into the pump chamber (21) from the through hole (22) as shown by the arrow in Figure 1.Most of the sucked water is absorbed by the rotor (7) as it rotates in this direction. However, it is quickly sent out along the straight part (24 x 24) to the open part (23), and from there the discharge waterway (28 liters) is fed into the discharge pipe (33) and the passage (4).
o) and is discharged from the F-direction outlet (41) into the 'T dehydration tank (2) via the lint filter (42).

There is very little water that comes out into the tank from the gap between (6) and the rotor (7), and this water immediately comes out of the dehydration hole (<10) and returns to the pump room ( 21) and is scraped away by the blades (9), resulting in abnormal foaming, which is less likely to occur. That is, since the short-circuit path of water in a short period of time is small, abnormal foaming is less likely to occur. In addition, the washing water flow becomes complicated because the water flow from the rotary blade (7) overlaps the water flow from the downward outlet (41) perpendicularly to the water flow from the downward outlet (41).
And 7, the laundry is concentrated directly below, and the laundry that is falling is hit and sinks under the water surface, so that it does not float to the surface.
Promote the change of one load of laundry and get 15! It is possible to improve the X-purity rate and the 4-way effect. Furthermore, lint and the like contained in the washing water can be reliably removed by the filter (42). As shown in this diagram,
The tip of (43) is the washing water level (L) (at high water level) l'
l(B) 11' method (J The sinking shift is caused by the laundry hitting the net (43) and the vibration at this time causing the unbalanced
)・(43) Push the thread waste away from its tip,
When cleaning the filter (42), thread waste can be easily removed from the thread (43).

If the discharge waterway such as the discharge pipe (33) is clogged with lint or the like and the amount of water from the downward outlet (41) decreases, it is necessary to clean the discharge waterway. In this case, remove the cover (37) on the top of the balance ring (34) and the discharge pipe (
33) and the C discharge channel (28) and retaining ring (
35) Remove it from the muff and make a muff, and the discharge %' (33)
It is possible to easily clean the passageway (40) and the no-hist property. ．． 4 Ru. In addition, the discharge waterway (28) is formed on one side outside the dehydration tank (2).This waterway (28) appears inside the dehydration tank (2) in appearance, which is good for appearance. , pump chamber (21) on the side wall of the dehydration tank (2)
) The discharge waterway is composed of a discharge pipe (33), so that C1 lint and the like do not come out from this part and spoil the external design.

, - The amount of water discharged from the discharge channel (28) is determined by the fact that the ridge (5) increases the channel area and has the effect of complicating the amount of lint captured and the amount of water 711L due to the increase in the relationship Lr: Strengthen each: iX exists. Therefore, the laundry is not moved around by the washing water flow, and is prevented from rising by the inwardly projecting bending part (36) on the discharge top (33), and the upper and lower parts are easily switched here. . Therefore, cleaning power is improved and uneven washing is reduced.

During dehydration, the discharge pipe (33) receives centrifugal force (J) and is pushed by the laundry and tries to deform, but the vertical groove (32)
) supports this and suppresses deformation. Therefore, the discharge pipe (33
) itself has similar strength, has a good I-C setting, is easy to manufacture, and is less likely to catch laundry during deformation and recovery.

(g) Effects of the invention According to the present invention, it is possible to secure the amount of water discharged, sufficiently improve the washing effect, and suppress uneven washing. We provide high-performance machines with a strong structure and high performance.
