Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a lint collection device for a washing machine that collects lint floating in water flow during washing and rinsing, and the present invention relates to a lint collection device for a washing machine that collects lint floating in water flow during washing and rinsing. A recessed part is provided in a part of the filter frame, which is removably attached to cover this recessed part, and a frame body with the opening side of the net fixed is rotatably supported on a filter frame with multiple through holes on both sides. However, by changing the angle of the frame due to the swirling and reversing water flow,
A net is used to collect floating lint, etc. in the water that has passed through the holes in the filter frame.

Conventional lint collection devices of this type include a frame body fixed to the front side of the overflow filter, which covers the front part of the overflow device of the washing machine and prevents the flow of cloth pieces, that is, the inside surface of the washing tub. A structure in which a waste collection net is attached, a structure in which a movable blade having a net, a lattice, or a wart-like protrusion is provided on the back side of the overflow filter, or a structure in which a suction cup attached to a frame is attached to the inner wall of the washing tub, and the frame is A structure in which a net is provided to collect floating lint in water is generally well known.

Among the above-mentioned conventional structures, those using suction cups have the problem that unless the plane of the washing tub is as smooth as a mirror, the suction ability of the suction cups cannot be fully guaranteed. If the load is equivalent to the rated load of the washing machine, the net will rest on top of the laundry and will only be able to collect a small amount of lint floating on the surface of the washing liquid. The problem is that it cannot be collected.

In addition, a configuration in which movable wings with a net or wart-like protrusions are placed on the back side of the overflow filter complicates the structure inside the overflow filter.
At present, it has not been put into practical use, and the overflow filter with a lint collection net attached to the front side has the disadvantage that the overflow water level cannot be adjusted.

The present invention eliminates the above-mentioned conventional drawbacks and provides a lint collection device with a simple structure and high collection efficiency.

An embodiment of the present invention will be described below with reference to the accompanying drawings. In the figure, reference numeral 1 denotes a washing tub, and a vertically long recess 1a is formed in the left rear corner of the inner wall, and a vertically long water inlet filter 2 is arranged to cover this recess 1a. The water inlet filter 2 has a substantially trapezoidal cross-sectional shape in the lateral direction, and bulges inward of the washing tub 1 when it is attached.

Reference numeral 3 denotes a water supply nozzle provided on the operation panel B portion of the upper part of the main body A that houses the washing tub 1, and communicates with the water supply side via an opening/closing knob.

Reference numeral 4 denotes a water receiving portion integrally provided at the upper end of the water inlet filter 2, which is located approximately horizontally and allows the water supplied from the water nozzle 3 to flow into the recess 1a and directly fall into the washing tub 1. Separate into water. The water supplied to the inside of the washing tub 1 is spread in a water film shape by the water receiving portion 4, resulting in a so-called shower water supply.

Reference numeral 5 denotes a lower slit provided at the lower part of the water inlet filter 2, which guides the water supplied into the recess 1a into the washing tub 1 from below. That is, this allows water to be supplied to the lower part.

Reference numeral 2a denotes a concave portion provided approximately in the longitudinally central portion of the water inlet filter 2, and bulges toward the concave portion 1a. Reference numeral 7 designates a filter frame which is removably engaged with the washing tub 1 side by claws 6 so as to cover the concave portion 2a.It has the same external shape as the water inlet filter 2, and has an opening for a lint collecting net 8 on the front side. A substantially square-shaped frame body 9 with its ends held is attached. This frame body 9
A shaft 10 is protruded from the top and bottom of the
is pivoted to rotate at a constant angle in the horizontal direction along the flow of water and cloth in the washing tub 1.

Reference numeral 11 designates side through holes provided on both side surfaces of the filter frame 7 to guide water flowing along the wall surface of the washing tub 1 into the lint collecting net 8 from the inside of the frame body 9. The rotation angle of the frame 9 is regulated by the frame 9 coming into contact with the inner surface of the concave portion 2a of the water inlet filter 2. As a result, water flowing along the wall surface of the washing tub 1 is regulated by the frame 9. The lint and the like contained in the flowing water are forced to pass through the lint collecting net 8. Naturally, the height position of this lint collecting net 8 is set at a position spanning from the low water level line to the high water level line so that it can be fully effective even when the overflow water level is changed or the washing water level is changed. It goes without saying that it is the most effective.

With the above configuration, the rotation angle of the frame body 9 is regulated by the concave portion 2a of the water inlet filter 2, and the rotation angle of the frame body 9 is regulated by the concave portion 2a of the water inlet filter 2. It is possible to prevent the fabric from being caught by the frame body 9 or damage the fabric thereby, and to collect floating lint flowing along the inner wall of the washing tub 1 with a high probability. Can be done. In addition, the lint collection net 8 can reliably catch water while flowing along the flow of water and cloth.
When cleaning the lint collection net 8, the filter frame 7 is removable from the water inlet filter 2, and since the filter frame 7 and the frame body 9 are easily removable, the lint collection is easy. Cleaning the net 8 is very easy. Also, unlike the suction cup type, the lint filter has never been installed unstable due to the unevenness of the inner wall of the washing tub.

In addition, in the overflow state, water is supplied from the lower slit 5 of the water inlet filter 2, so the water flow removes lint from the bottom of the washing tub into the frame 9.
The lint collection net 8 can float up to this position and collect the lint, and the lint collection effect becomes even more excellent.

In addition, the lint collecting net 8 is attached to the water inlet filter 2, and the height of the frame 9 is set so that it is sufficiently effective for each overflow water level.
This makes it possible to adopt the conventional multi-stage overflow structure, and solves the problem that the overflow water level could not be adjusted when a lint filter device was attached to the overflow filter 13.

In addition, there is a discharge circulation lint collection system in which blades or a whirlpool chamber are formed on the back side of a pulsator placed at the bottom of the washing tub 1, a discharge waterway is provided in communication with the back side of the pulsator, and a filter such as a net is attached to the outlet of the pulsator. was proposed, but when comparing this with the configuration of this embodiment, the former has a better lint collection effect when the discharge amount is large, but the lint passes near the pulsator. This has disadvantages in that lint gets wrapped around the pulsator and causes it to lock, and dirt, grime, mold, etc. tend to form in the shadows of the discharge channel due to powder soap, phosphorus-free detergent, etc. . However, according to this embodiment, since almost the entire portion of the lint collection net 8 is exposed to the washing tub 1, there are few hidden areas, and the above-mentioned former problem does not occur.

As described above, according to the present invention, the recessed portion is provided in the approximately central portion in the length direction of the vertically long water inlet filter,
A frame holding the open end of a lint collecting net is rotatably attached to the inside of the filter frame which is removably provided in the recessed part, and a frame body holding the open end of the lint collecting net is rotatably attached to both side portions of the filter frame that protrude inside the washing tub. A side hole is provided to communicate the opening of the lint collecting net with the inside of the washing tub, and the frame body can be freely moved so that the opening of the lint collecting net faces the water flow in the washing tub. It can be rotated, and the lint collection efficiency is very good.Moreover, there is no fear that the lint collection net will come off or be damaged due to contact with the laundry, and the collected lint can be The filter frame can be easily removed by attaching and detaching the filter frame.
