〔Example〕

One preferred embodiment of the invention and some variants thereof will be described below with reference to the accompanying drawings.

Referring to the drawings, the clothes washing machine comprises a cabinet 1 which houses an electric mower 2 for driving a mechanical device, which mechanical device has a shaft for stirring an agitator 3 inside a pivot tub 4. The pivot tab 4 is mounted inside the watertight container 6 with a space 5 therebetween. The drive mechanism preferably comprises an electric motor 2 connected directly to the agitator drive shaft 7 or by means of a pulley and belt (not shown), with interconnection means connecting the drive shaft and the pivot tab 4. The pivot tabs are connected so that when the drive shaft 7 is continuously rotated in one direction, this pivot tab is rotated to impart a pivoting movement to the garment therein.

This electric motor 2 is preferably electrically controlled and periodically reversed to provide the stirring action, and at appropriate time intervals switched to provide continuous rotation of the rotor to provide the swirling action. Primer U.S. Patent No. 3,914.9
No. 63 discloses an agitator drive which, when continuously rotated in one direction, also continuously drives the pivot tab in this direction. A drain 9 is provided in the container 6, which opens in the usual manner to a drain pump 17.

The pivot tab 4 has a counterbalancing ring 10 near its upper edge and has a series of openings 11 oriented with their edges towards the outside of the pivot tab.

These holes are preferably round cut holes with a diameter of about 4 mm. Another series of openings 12 are provided in the lower part of the pivot tab, and a shield or guide 13 is provided above these openings 12, which apertures 12 are located substantially in the pivot tab above the bottom 14 of the pivot tab. Mounted on a vertical cylindrical wall.

The pivot tab is preferably, but not necessarily, a stepped drum as described in my US Pat. No. 4,392,372.

The stirrer 53 has a hollow column 20 with a series of grooves 21 located midway along the length of the column 20 and leading from the interior of the swirling bowl 4 into the interior of the column 20. The agitator 3 has an outer vane 16 which is connected to the column 20.
and an upper surface of upper disk 22 (described below).

At its lower end, the agitator extends outwardly to form an upper disk 22 and a lower disk 23 with a space 26 between them, which is divided by radial vanes 18. , since the purpose of providing the two discs and the space is to provide an impeller for a centrifugal pump. Such an impeller may also be provided in other ways, for example by providing an independent centrifugal pump. You can also do it.

The outlet 24 is provided between the disks 22 and 23 at or near the outer edges of these disks, the outer edge 25 of the upper disk being directed downwards and acting close to the inner edge of the guide 13.

The bottom 14 of the pivot tab is stepped as described above;
There is a space between each tier, and the space 15 between the tiers provides a passageway for water to be wicked as described below.

If necessary, a container 27 is mounted on the column 20,
This container is used to store the clothes in a known manner.

The operation of the above structure is as follows.

When this clothes washing machine is loaded with the clothes placed in it and it starts operating, the washing liquid, e.g. water and detergent, flows into the container 6 and rises to the required height. , and the stirrer 3 is set to swing backward and forward.

As a result of this movement, a centrifugal pumping action occurs between the disks 22 and 24, assisted by the vanes therein (if provided), which centrifugal pumping action circulates the washing liquid and this The lint is carried in the liquid in the usual manner and enters the hollow column 20, passing downwards between the disks 22 and 24 and outwardly, passing through the space 15 below the guide 13. and is discharged through the opening 12 into the space 5 between the container 6 and the pivoting tab 4. The washing liquid is therefore sucked upwardly into the space 5 between the tub 4 and the container 6 and then passes downwardly across the tub 4 through the hollow post 20 and the process is repeated.

However, the re-entry of lint through the openings into the washing liquid well is limited, firstly by the size of these openings and secondly by the walls of these openings.
Thirdly, the flow of fluid through the openings 11 is slow and thus prevents the inflow of lint. The lint will collect in the space 6 and either rise to the top, as schematically shown at 28, or settle to the bottom of the container, depending on the nature of the lint.

Once the wash cycle is complete and the drain cycle begins,
The drain 9 is opened and water flows out through the drain channel, resulting in a draining action of the kernels and, more preferably, a jet rinse with appropriate speed rotation of the perforated tab as part of the operation. Due to the inflow of rinsing water during the cycle, the lint collected in the space 6 becomes flushed out downwardly and outwardly via the drain pump.

The problem of lint accumulation is thus substantially eliminated by the present invention, at least when carried out in the preferred manner described above. To effect some pivoting of the pivot tab, microprocessor 30 (FIG. 2) commands motor 2 to rotate continuously while pump 17 is driven at pump speed. If a rinsing operation is to be performed again, the motor pulp 31 is actuated to open again. Below margin
