Description

[Detailed description of the invention] The present invention relates to a dehydrating washing machine that has a rotary blade at the bottom of the washing/dehydrating tank, and when washing or rinsing, the water in the dehydrating tank is sucked into the pump chamber on the back side of the rotary blade. The water is sent from the lower side of the dehydration tank to the upper part of the side wall to a discharge channel with a certain shape, and is discharged from above into the dehydration tank, and the discharged water complicates the water flow to improve the cleaning rate and rinsing efficiency. in,
In particular, it is intended to reduce water leakage from the discharge channel and to allow the discharge channel to be easily shaped.

This will be explained below based on the drawings.

Reference numeral 1 denotes an outer tank, and a resin washing/drying tank 2 is housed inside.

The side walls of the dehydration tank 2 are composed of an arcuate wall 2' and a flat wall 2'' as shown in Figure 2.
It is roughly octagonal in shape.

A rotor blade 5 fixed to a rotor shaft 4 is disposed in an opening 3 at the center of the bottom of the dehydration tank 2, and a plurality of back blades 6 are provided on the back side of the rotor blade 5.

A rib 7 that is concentric with the opening 3 and surrounds the back blade 6 is integrally suspended from the outer bottom surface of the dehydration tank, and a plurality of bosses 8 are integrally provided on the rib 7.

Reference numeral 9 denotes a dehydration tank substrate fixed to the dehydration tank drive shaft 31. The rib 7 and the lower end of the boss 8 are in contact with the substrate 9, and by screwing the tightening screw 10 into the boss 8, the dehydration tank can be opened. 2
and the substrate 9, and also closes the opening 3.

The dehydration tank 2 is attached to the dehydration tank board 9 by the pump action of the back blade 6.
and the water between the outer tank 1 (which eventually becomes the water in the dehydration tank 2).

A plurality of suction ports 12 are provided for sucking the water into the pump chamber 11 formed by the substrate 9 and the ribs 7.

The rib 7 does not surround the entire circumference of the back blade 6, but is partially open 13 as is clear from FIG. It is fed into a discharge channel 14 formed from the outer bottom surface to the upper end of the outer wall.

Here, the discharge waterway 14 is formed integrally with the dehydration tank by injection molding from the outer bottom surface of the dehydration tank to the upper end of the outer wall (the side wall in this case is the flat wall 2'').

Figure 3 shows the state when it is shaped, and the part of the discharge waterway 14 that is shaped on the outer bottom is shaped by the side core 15, and since this side core is pulled out to the left in the figure, the discharge waterway A punched hole 16 is formed in a part of the corner extending from the bottom of the dehydration tank 14 to the side wall.

Therefore, this hole 16 is closed with a lid 17 to form a discharge waterway 14.

In FIG. 3, numeral 18 is a mold for pulling out upwardly, and 19 is a molding die for pulling out downwardly.

At the upper end of the dehydration tank 2, there is a liquid 20 that acts as a balancer.
A hollow annular balance ring 21 containing
At a proper place on this balance ring, one end is connected to the discharge waterway 14.
A water passage 23 is connected to the upper end of the dehydration tank and has the other end 22 open toward the inside of the dehydration tank.

In other words, the concave portions 24 and 25 that are continuously provided at appropriate locations on the outer circumferential wall and the earthen wall of the balance ring are covered with a cover 26 to form the water passage 23.

A bearing case 27 for the rotor shaft 4 and the dehydration tank shaft 10, and a drive motor 28 are attached to the back surface of the outer tank 1, and such an outer tank is suspended from the upper part of the machine frame (not shown) in a vibration-proof manner. ing.

In the structure described above, when the rotary blade 5 rotates during washing or rinsing, due to the pumping action of the back blade 6,
As shown by the arrow in FIG. It passes through a water passage 23 connected to its upper end and is discharged from the opening 22 into the dewatering tank.

As a result, the water flow in the dehydration tank becomes a complicated turbulent flow due to the combination of horizontal rotation by the rotary blades and water discharged from the opening 22, and the laundry A is frequently changed from top to bottom.
In particular, since the water falls above and below the laundry, the laundry above will no longer swell up with air and remain floating on the water surface, eliminating uneven washing and improving cleaning and rinsing efficiency.

Also, here, the amount of water sucked into the pump chamber 11 is made larger than the amount of water flowing out between the dehydration tank 2 and the outer tank 1 from the dehydration hole 29 on the side wall of the dehydration tank, so that the water can be removed as shown in Fig. 1 during washing or rinsing. The water level of the water tank is raised above the water level between the dewatering tank and the outer tank, so that the water between the two tanks 1 and 2 can effectively contribute to washing and rinsing.

As described above, according to the present invention, the water sucked into the pump chamber between the outer tank and the dehydration tank is sent to the discharge channel formed from the bottom of the dehydration tank and above the side wall, and is discharged from above the dehydration tank into the dehydration tank. Since the water flow is complicated, the laundry can be changed from top to bottom frequently, which improves the washing rate and rinsing efficiency.

The discharge waterway can be formed integrally with the dehydration tank except for a cut-out hole formed in a part of the corner of the bottom side wall of the dehydration tank, and can be completed by simply covering the cut-out hole with a lid. Therefore, productivity is improved, and there is almost no amount of water leaking directly from the discharge channel to the outer tank or dehydration tank, and most of the water sucked into the pump room can be discharged from above the dehydration tank, allowing it to flow directly into the pump room. The sucked water can be effectively used to improve cleaning and rinsing efficiency.

Furthermore, it has various effects such as preventing thread waste floating in the water from protruding out of the discharge channel and damaging the appearance.

If a bag-shaped lint filter 30 is attached to the opening 22 as shown by the dotted line in FIG. 1, the lint filter 30 can easily capture lint floating in the water.

At this time, since the discharge waterway 14 is integrated with the dehydration tank, a large amount of water can be passed through the lint filter at once, and the filter effect can be exerted in a short time.

Furthermore, if the discharge waterway extends into the dewatering tank, the cleaning efficiency can be further improved.
