Description

[Detailed Description of the Invention] Traditionally, in two-tank dehydrating washing machines, the dehydrating tank side Various dehydrating and rinsing type washing machines have been proposed.

However, this type of washing machine has the disadvantage that the rinsing process is slightly more variable than the rinsing method in which washing is carried out in the washing tub.

Among them, the one that is considered to be a rational dehydration rinsing method with little variation is to first dehydrate the laundry that has been transferred to the dehydration tank, and then supply water to the dehydration tank up to a certain water level.
This method automatically repeats the cycle of rotating and stirring the spinner in the water to evenly soak the laundry, and then draining the water. During spin-drying, the laundry is pressed against the inner peripheral wall of the spin-drying corner, blocking the drain hole of the spin-drying corner.As a result, when the next time water is supplied, the water that has accumulated in the spin-drying tank will flow into the spin-drying basket. As water becomes difficult to penetrate into the laundry, water does not penetrate effectively into the laundry, resulting in very poor rinsing efficiency.

The present invention has been made to solve the above problems, and one embodiment of the present invention will be described below with reference to the accompanying drawings.

In FIG. 1, 1 is a washing machine main body, and a washing tub 3 having a pulsator 2 at the bottom is installed inside this main body 1.

Reference numeral 4 denotes a motor installed at the inner bottom of the main body 1, and this motor 4 rotates the pulsator 2 via a belt 5.

Reference numeral 6 denotes a dehydration basket having a plurality of dehydration holes 7 formed in the peripheral wall and the inclined bottom portion, and a dehydration cap 8 having a plurality of drainage holes 8' is removably attached above the dehydration basket 6.

Reference numeral 9 denotes a dehydration tank in which a dehydration valve 6 is rotatably installed, and above the dehydration tank 9, a dehydration receiver cover 12 to which an annular nozzle 11 having a large number of injection ports 10 is fixed is arranged.
14 is a dehydration lid, 14 is a buffer provided at the bottom of the dehydration tank 9, 15 is a dehydration motor that rotates the dehydration cup 6 via a dehydration shaft 16, and 17 is an electromagnetic drain valve of the energized closure type.
Reference numeral 18 denotes a panel section disposed above the main body 1, and this panel section 18 is equipped with a washing side timer 19, a washing side drain cock 20, a dewatering rinse timer 21, etc.

22 is a hose that connects the annular nozzle 11 and the electromagnetic water supply valve 23.

In FIG. 2, reference numeral 24 denotes a holding part with a cross-section shaped like an ellipse, which is located at approximately the middle height of the dewatering head 6, and 25 is an intermediate cap that is detachably installed on the holding part 24. 25, as shown in FIGS. 3 and 4,
It is integrally constructed of resin such as vinyl chloride through two flat ribs 28 which have an opening 26 in the center and have cutouts 27 radial from the central opening 26 to enlarge the width of the central opening 26. It is something that

Due to the presence of the ribs 28, an appropriate space 29 is formed between the two flat plates.

Further, the dehydration hole 7 in the center of the dehydration cup 6 and the opening 26 of the intermediate cap 25 communicate with each other via the space 29.

The operation in the above configuration will be explained.

First, the laundry washed in the washing tub 3 is transferred to the spinner tub 6.

In this case, after putting the laundry in the lower half of the dehydrator 6,
When the intermediate cap 25 is attached, the laundry is put into the upper half of the spinner pot 60, the spinner cap 8 is attached to the upper inner peripheral wall of the spinner tube 6, and the dehydration silver ski timer 21 is set. Dehydration is performed.

Thereafter, water is supplied from the annular nozzle 11 into the spindle 6, but in this case, the water supplied into the spindle 6 is absorbed by the laundry, and the water accumulated in the spinner tank 9 is removed from the center of the spindle. It enters into the space 29 of the intermediate cap 25 through the hole 7.

The water that has entered this space 29 permeates the laundry above and below the central opening 26 of the intermediate cap 25.

After water is supplied to a certain level, stirring is performed by rotating the dehydration lever 6.

When this stirring is finished, the water in the dehydration tank 9 is drained.

Dehydration and rinsing is performed by repeating the cycle of dehydration, water supply, stirring, and drainage several times in this way.

As described above, according to the present invention, two flat plates are stacked, each having an opening in the center and having cutouts radially extending outward from the opening, located at approximately the middle height of the dehydration corner.
By arranging an intermediate cap with a space between these two flat plates and communicating the dehydration hole of the dehydration corner and the opening of the intermediate cap through the space of the intermediate cap, dehydration, water supply, stirring, and Even if most of the dehydration holes are blocked by laundry during dewatering in the drainage cycle, the water accumulated in the dehydration tank will enter through the dehydration hole that communicates with the space in the middle gap, and the space in the middle cap will still flow. It effectively penetrates into the laundry above and below the central opening through the central opening, further improving rinsing efficiency.
