Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a lint collection device that collects lint generated in washing water when a washing machine is used, that is, during washing, rinsing, etc. A pressure chamber is provided at the bottom of the water tank under which the rotor blade is installed, and an inlet and an outlet are provided in communication with the pressure chamber, and a plurality of blades are formed on the lower surface of the rotor blade, and a plurality of blades are formed on the lower surface of the rotor blade. When washing and rinsing, the water in the aquarium is guided to a filter installed above the water level during washing and rinsing, lint, etc. are filtered out by this filter, and the water is returned to the aquarium. , which aims to improve the collection performance of lint waste.

In conventional washing machines, a filter is installed below the water surface in the water tank, and lint is filtered and collected by the water flow generated by the rotary blades. It is not stable, has poor filtration performance, and because filtration is carried out underwater, the water flow may reverse when the rotation direction (water flow direction) of the rotor changes or when the rotor blades change the rotation direction (water flow direction). When the lint becomes loose or stagnates, it tends to separate from the filter, resulting in poor lint collection performance.

Furthermore, a method has been proposed in which vanes are provided on the lower surface of the rotor to suck in washing water from the outside of a filter installed below the water surface by a pump action, and the lint is filtered by this suction force, but this method is also similar to the above-mentioned method. Similarly, since the filter is located below the water surface, thread waste tends to separate from the filter due to water stagnation when the system is stopped.

The present invention solves the above-mentioned conventional drawbacks, and an embodiment thereof will be described below with reference to the drawings. Reference numeral 1 denotes a water tank in which a rotary blade 2 is rotatably provided, and a recessed portion in the bottom of which the rotary blade 2 is housed. 3 is formed.

The recessed portion 3 has an outlet 4 and an inlet 5 at its outer diameter.

Reference numeral 6 denotes a water inlet cover provided at the corner of the aquarium 1 in order to guide water from the faucet to the bottom of the aquarium 1, and has a through hole 7 therein.

A hose 8 connects the bottom of the water supply port 9 and the inlet 5, and on the bottom side of the water supply port 9, a suction port provided on the wall of the water tank other than the bottom where the rotary blade is installed is used.

Reference numeral 10 denotes a nozzle installed on the operation panel 11 above the water levels a and b during washing and rinsing, and one end of which is connected to the outlet 4 with a hose 12.

Reference numeral 13 denotes a filter that is removably attached to the inner wall of the aquarium or the panel 11 and is located between the nozzle 10 and the water level ayb.

Next, to explain the vicinity of the rotor blade 2 and the recessed part 3, a plurality of blades 14 are formed on the lower surface of the rotor blade 2, and in the recessed part 3, the blades 14 are located outward from the external orbit A of the blade 14. A frame 15 is formed, thereby configuring a pressure chamber 16, and both ends of the frame 15 are connected to the mouth of the outlet 4.

Further, near the mouth of the outlet 4, a substantially triangular protrusion 17 consisting of three substantially arc-shaped surfaces is formed, and one surface of this protrusion 17 is
This is very close to the outer orbit A of the blade 14.

Further, the projection 17 has its center on a line passing through the center of the rotary blade 2 and the center of the fourth outlet, and is symmetrical with respect to the line.

The pressure chamber 16 has a maximum clearance at a corresponding portion B1 of the outlet 4, that is, a point symmetrical to the outlet 4 with respect to the external orbit A of the blade 14, and the pressure is reduced. The gap becomes narrower as the distance approaches the surface 18.1 of the projection 17 for guiding pressurized water.
A portion C between 9 and the frame 15 is the smallest gap.

In other words, when the rotor blade 4 rotates clockwise, the water in the pressure chamber 17 is
The pressure chamber is gradually pressurized from part B to part C, and is strongly discharged as shown by the solid arrow.

When turning counterclockwise, it is ejected strongly as shown by the dashed arrow.

As a result, the pressure in the pressure chamber 16 decreases, and water enters from the inlet 5 in conjunction with the increase in water pressure in the water tank.

That is, water is continuously replenished and discharged, and a pumping action is performed.

Next, to explain the lint collection function, lint generated during washing and rinsing enters the pressure chamber 16 from the through hole 7 of the water inlet cover 6 through the hose 8 and the inlet 5 by the pump action of the rotor 2. Pressurized.

Next, the water is discharged from the outlet 4 through the hose 12 and from the nozzle 10 into the filter 13, where the water is filtered, the lint is collected in the filter, and the water is returned to the water tank 1.
taken back inside.

In other words, water is constantly being circulated while the rotor is rotating.

The thread waste collected by the filter 13 is transferred to the filter 13.
Since it is above the water surface, it is completely unaffected by the water flow when the rotating direction of the rotor changes or when it stops, and it is always accumulated in the filter, so it reliably removes most of the lint generated in the aquarium. There will be less lint and turbidity in the aquarium.

As a result, the amount of lint adhering to the items to be washed is reduced, and the rinsing time can be shortened.

As described above, according to the present invention, the lint collection ability is high and stable collection is possible, thereby shortening the rinsing time. Due to this relationship, the ability to circulate water containing lint is very good, and lint can be collected accurately.

Additionally, since the filter is located above the water surface, it also has the advantage of making it easier to dispose of lint.
