The filter also comprises a plurality of flow passages which are communicated with the cavity and the inner side of the washing barrel. In the invention, the filter cover is attached to the side wall of the washing barrel under the action of centrifugal force to compress and collect accumulated scraps, and simultaneously a part of flow channels are blocked, so that most of water in the washing barrel only flows into the scraps filter through the filter cover, and the scraps are flushed out of the filter and discharged out of the washing barrel along with the water outlet, thereby realizing the self-cleaning function. The washing tub is a rotatable structure arranged in the washing machine and used for accommodating clothes, and the inner side of the washing tub is a space defined by the side wall and the bottom wall of the washing tub.
The further scheme of the invention is as follows: the filter cover is restrained by the elastic part 3, is attached to the inner side wall of the washing barrel or forms a gap under the action of centrifugal force generated by the rotation of the washing barrel, and closes or conducts a flow passage formed by the gap; preferably, the thread scrap filter comprises a normally open flow passage and a controllable on-off flow passage, and the filtering cover 2 seals the controllable on-off flow passage under the action of centrifugal force and is still communicated with the normally open flow passage.
In the scheme, the filter cover is restrained by the elastic piece, when the elastic piece is in a loose state, a certain gap is formed between the filter cover and the side wall of the washing barrel, and the gap forms a flow passage which is communicated with the inner side of the washing barrel and penetrates through the inside of the thread scrap filter; and when the elastic piece is in a compressed state, the filter cover is attached to the side wall of the washing barrel, so that the gap disappears, and the effect of sealing the flow channel is achieved. In the preferred scheme of the invention, the structure of the filter cover is improved, when the filter cover is attached to the side wall under the action of centrifugal force, part of the attachment surface is attached to the side wall, a space is reserved between the other part of the attachment surface and the side wall, the structure attached to the side wall plays a role in blocking the flow channel, the flow channel of the controllable channel is formed, and the part with the space reserved on the side wall is always kept communicated with the flow channel, so that the normally open flow channel is formed.
The further scheme of the invention is as follows: the filter is characterized by also comprising a filter base 1, wherein two ends of the washing barrel in the depth direction are provided with first water gaps, and two sides of the washing barrel in the circumferential direction are provided with second water gaps 11; the filter cover 2 is connected to the inside of the filter base 1 in a limiting way through the elastic part 3 and forms a first flow passage and a second flow passage with the first water gap and the second water gap 11 respectively, and the centrifugal force generated by the rotation of the washing barrel compresses the elastic part 3 to ensure that the filter cover 2 is attached to the side wall of the washing barrel to seal the second water gap 11; preferably, the first flow channel is a normally open flow channel, and the second flow channel is a controllable on-off flow channel; more preferably, when the filter cover 2 is attached to the sidewall of the washing tub, the first flow path is closed from the lower end of the washing tub in the depth direction.
In the above solution, since the filter cover covers the opening, the filter is provided with a water gap in the axial direction and the circumferential direction of the washing tub, and the water gap and the filter cover jointly form a first flow channel and a second flow channel for water flow, further, the filter cover is connected with the filter base via the elastic element, when the centrifugal force generated by the rotation of the washing tub is large, the elastic element is compressed by the centrifugal force to make the filter cover move towards the side wall of the washing tub, and the displacement overcoming the damping of the elastic element can drive the thread scraps in the filter to move towards the side wall of the inner tub, so that the thread scraps and other dirt are concentrated to be washed away by water flow and discharged. The thread scraps filter can utilize a pump blade below the impeller to pump water into the filter from the bottom of the filter through the first flow passage and flow into the washing barrel from the filter cover, so that circular filtration is realized, and the second flow passage is communicated with the washing barrel, so that the water body in the washing barrel can be further filtered. The structure of the filter cover is improved, so that when the filter cover is attached to the side wall of the washing barrel, part of the attachment surface is attached to the side wall, a space is reserved between the other part of the attachment surface and the side wall, the structure attached to the side wall blocks a second flow channel serving as a controllable on-off flow channel, and the part reserved with the space on the side wall keeps the smoothness of a first flow channel serving as a normally open flow channel. In another embodiment of the present invention, when the filter cover 2 is attached to the sidewall of the washing tub, the first flow channel is closed from the lower end of the washing tub in the depth direction, and the upper end is kept open, so that a flow channel with one end being controlled to be opened and closed is formed.
The further scheme of the invention is as follows: the filtering cover 2 is provided with a filtering port 21 facing the inner side of the washing barrel, and two sides corresponding to the second water gap 11 are respectively provided with a flanging 23 extending to the side wall of the washing barrel; preferably, the filtering cover 2 is provided with a flanging 23 at the lower end corresponding to the depth direction of the washing tub.
In the scheme, the two sides of the filter cover in the circumferential direction of the washing barrel are provided with the flanges, so that when the filter cover is acted by centrifugal force, the flanges are tightly pressed on the side wall of the washing barrel, and the flanges pressing the side wall block the second water gap to seal the second flow channel; the filtering cover is not provided with the flanging in the depth direction of the washing barrel, so that a certain space is formed between the middle bottom of the filtering cover and the side wall of the washing barrel under the support of the flanging at the two sides, and the conduction of the first flow channel is realized. Preferably, a flange is arranged at one end of the filter cover corresponding to the bottom of the filter base, so that the first flow passage is cut off from the bottom, and the second flow passage is cut off from two sides, at the moment, water flow can only enter through the filter opening of the filter cover and flow out through the first water gap at the top of the first flow passage, and the flushing of the inside of the thread scrap filter by the water flow in the barrel is realized.
The further scheme of the invention is as follows: the side wall of the washing barrel is obliquely arranged from the bottom of the washing barrel to the opening of the washing barrel in a trend away from the axis of the washing barrel, and a water outlet is formed in the top of the washing barrel.
In the above scheme, the lateral wall of the washing barrel is inclined outwards from the bottom to the top, so that when the water body in the washing barrel is acted by a centrifugal force, the water body penetrating through the filter cover flows upwards, and the thread scraps in the thread scraps filter are flushed to the water outlet on the outer side of the top of the washing barrel, thereby realizing self-cleaning of the thread scraps.
The further scheme of the invention is as follows: the centrifugal force generated by the washing machine in different operation procedures is different, and the elastic part 3 is in a loose or compact state under the action of the centrifugal force; when the elastic part 3 is in a compressed state, the filter cover 2 is attached to the side wall of the washing barrel, the first flow passage is communicated, the second flow passage is closed, the water body in the washing barrel flows through the filter opening 21 under the action of centrifugal force, and the water body in the first flow passage flush the interior of the thread scrap filter together, flow upwards along the inclined barrel wall and are discharged through the water outlet; when the elastic element 3 is in a loose state, the filter cover 2 is far away from the side wall of the washing barrel, the first flow passage and the second flow passage are both communicated, and water flows into the washing barrel from the inside of the thread scraps filter through the filter opening 21; preferably, when the elastic member 3 is in a compressed state, the filter cover 2 is attached to the side wall of the washing tub, the second flow passage is closed, the lower end of the first flow passage is closed, the upper end of the first flow passage is communicated, and a water body in the washing tub flows into the filter opening 21 under the action of centrifugal force and washes the interior of the lint filter, and then flows upwards along the inclined tub wall and is discharged through the water discharge opening.
Among the above-mentioned scheme, the washing machine is the rotational speed of washtub different when the different procedure of operation, and the rotational speed is lower when for example washing, and the centrifugal force of production does not reach and makes the elastic component take place the degree of deformation, and the elastic component is in lax state this moment, and the filter cover of spacing in the filter base is close to the washtub axis, makes the interior cavity that supplies the washing water inflow of formation of filings filter and enough hold the filings foul, realizes the filtration to the washing water. In the dewatering or rinsing stage (or a specific procedure that the rotating speed of the washing barrel is higher), the rotating speed of the washing barrel is increased, the generated centrifugal force overcomes the damping of the elastic piece to enable the elastic piece to be compressed and deformed, the filter cover compresses and concentrates the thread scraps enriched in the filter, and meanwhile, water in the washing barrel flows outwards through the filter opening of the filter cover and is flushed together with the water body in the first flow passage to discharge the thread scraps. The thread scraps filter can pump water into the filter by utilizing pump blades below the impeller, so that the circular filtration is realized. Therefore, when the elastic element is in a loose state, water flow enters the cavity formed by the filter cover and the filter base from the bottom of the filter under the action of the pump blade structure and flows into the washing barrel through the filter opening, so that thread scraps and dirt contained in the water body are kept on the filter opening. When the elastic piece is pressed tightly, the filter cover compresses and collects thread scraps and dirt in the filter, at the moment, the pump blade below the impeller continuously pumps water into the filter from the bottom of the filter base (or the operation of pumping water into the filter is not executed when the filter cover cuts the bottom end of the first flow channel), the water in the washing barrel also washes the inside of the filter through the filter opening under the action of centrifugal force, and meanwhile, the washing machine controls the opening of the upper water discharging opening to realize that the water flow flushes the collected thread scraps and dirt to the water discharging opening and discharges the thread scraps and dirt out of the machine.
The further scheme of the invention is as follows: the elastic element 3 is connected with the filter base 1 and the filter cover 2 along the radial direction of the washing barrel; preferably, the filter base 1 is provided with attachment points 13 for the elastic element 3 against the side wall of the washing tub.
In the above solution, in order to make the centrifugal force better overcome the damping of the elastic member, the constraint direction of the elastic member is set along the centrifugal force direction of the washing tub. When the orientation of the filtering port is consistent with the constraint direction of the elastic piece, the filtering area of the filtering cover is over against the inner side of the washing barrel, so that the filtering effect is more uniform. The thread scraps filter is arranged on the inner side wall of the washing barrel, the constraint direction of the elastic piece is coincided with the radial direction of the washing barrel, so that the centrifugal force is better conducted to the elastic piece, and the filter cover is convenient to compress and collect thread scraps and dirt in the filter. The filter base is provided with a plurality of points for connecting the elastic parts at the position close to the side wall of the washing barrel, so that the displacement distance of the filter cover under the action of centrifugal force is longer, and the compression and collection of thread scraps and dirt are facilitated.
The further scheme of the invention is as follows: limiting plates 12 are respectively arranged on two sides of the filter base 1 in the depth direction of the washing barrel, and when the elastic piece 3 is in a loose state, the filter cover 2 is abutted against the limiting plates 12.
In the above scheme, the upper end and the lower end of the filter base are provided with limiting plates, the limiting plates are close to the axis of the washing barrel and form the surface of the thread scrap filter, openings corresponding to the filter covers are formed between the limiting plates, and the length of the filter covers in the depth direction of the washing barrel is greater than that of the openings, so that the top and the bottom of the filter covers are respectively abutted against the limiting plates when the elastic piece is in a loose state.
The further scheme of the invention is as follows: the second water gap 11 comprises a plurality of water distribution plates 111 which are uniformly distributed, and the water distribution plates 111 extend towards the inside of the washing barrel and clamp the filter cover 2; preferably, the extension length of the water diversion plate 111 is twice the thickness of the flange 23.
In the scheme, the filter base is provided with a plurality of water distribution plates which are distributed in parallel on two sides of the circumference of the washing barrel, and the water distribution plates and the side edge of the filter cover when the elastic piece is loosened form a plurality of flow channels in an enclosing mode to form a second water gap for water to flow into. The water diversion plate can intercept the thread scraps in the water body. When the elastic piece is pressed, the filter cover is pressed against the side wall of the washing barrel, the flanging of the filter cover is flush with the root of the water distribution plate, the second water gap is closed, and water flow in the washing barrel cannot flow into the second flow passage from the side surface and only can flow into the second flow passage through the filter opening. In order to ensure the smoothness of the water flow passing through the second flow passage when the elastic part is in a loose state, the flanging of the filter cover is not too thick, so that the interval between the flanging and the root part of the water distribution plate is enlarged, the caliber of the second water gap is increased, and the water flow passing through the second water gap is improved.
The further scheme of the invention is as follows: the filter cover 2 is provided with guide grooves 22 at two ends of the depth direction of the washing barrel, and the limiting plate 12 extends towards the side wall of the washing barrel to be provided with guide columns matched with the guide grooves 22.
Among the above-mentioned scheme, because washing machine operation in-process rivers and the effect of centrifugal force are inhomogeneous, the elastic component is recovering to when lax by compressing tightly, thereby the atress is uneven can lead to filtering the unable normal reset of lid and influence the filter effect. Therefore, the mutually matched guide structures are additionally arranged on the limiting plates of the filter cover and the filter base, so that the displacement of the filter cover along with the deformation of the elastic piece is smoother.
The further scheme of the invention is as follows: and a filter screen for covering the filter opening 21 is arranged on one surface of the filter cover 2 facing the side wall of the washing barrel.
In the above scheme, the filter cover is provided with a plurality of closely arranged filter openings, each filter opening is covered by the filter screen on the inner side of the filter cover, and the filter openings are more, so that the filter effect can be ensured when larger water flow penetrates through the filter openings.
The invention also provides a washing machine, and the inner side wall of the washing barrel of the washing machine is provided with the thread scrap filter.
After adopting the technical scheme, compared with the prior art, the invention has the following beneficial effects:
1. the thread scrap filter comprises a fixed frame and a filter cover capable of moving in the fixed frame, wherein the filter cover which is positioned in a filter base is limited to move under the action of the centrifugal force of a washing barrel, so that thread scrap dirt in the filter is compressed and collected, and then the thread scrap is discharged out of the machine under the washing of washing water flow to realize self-cleaning;
2. the thread scrap filter comprises a semi-open frame structure, wherein a limiting structure for limiting a filter cover is arranged at the upper part of the semi-open frame structure, the limiting structure surrounds an opening, and a displaceable filter cover is communicated with the inner side of a washing barrel through the opening, so that the limitation of the filter cover is realized, and conditions are provided for larger water flow to penetrate through a filter opening;
3. the thread scrap filter further improves the matching structure of the filter cover and the filter base, and is provided with the guide post and the guide groove, so that the failure of resetting the filter cover due to uneven stress when the elastic part is deformed is prevented.

The filter cover is provided with a plurality of closely arranged filter openings, each filter opening is covered by a filter screen on the inner side of the filter cover, and the filter effect can be ensured when large water flow penetrates through the filter openings due to the large number of the filter openings.
Example 2
This example differs from example 1 in that:
in this embodiment, when the filter cover 2 is tightly attached to the sidewall of the washing tub, the first flow path is closed from the lower end of the washing tub in the depth direction. The lower end of the filter cover 2 corresponding to the depth direction of the washing barrel is provided with a flanging 23.
In the embodiment, the structure of the filter cover is improved, so that when the filter cover is attached to the side wall of the washing barrel, part of the structure of the attachment surface is attached to the side wall, a space is reserved between the other part of the attachment surface and the side wall, the structure attached to the side wall blocks the second flow channel serving as the controllable on-off flow channel, and the part reserved with the space on the side wall keeps the smoothness of the first flow channel serving as the normally-open flow channel. On the basis, one end of the filter cover corresponding to the bottom of the filter base is provided with a flanging, the lower end of the filter cover in the depth direction of the washing barrel seals the first flow channel, and the upper end of the filter cover is communicated, so that the first flow channel with one end being controlled to be on and off is formed. And the second runner is cut off from two sides, at the moment, water flow can only enter through the filtering port of the filtering cover and flows out through the first water gap at the top of the first runner, and the flushing of the water flow in the barrel to the inside of the thread scraps filter is realized.
In this embodiment, when the elastic member 3 is in a compressed state, the filter cover 2 is attached to the side wall of the washing tub, the second flow channel is closed, the lower end of the first flow channel is closed, and the upper end of the first flow channel is open, and a water body in the washing tub flows into the filter opening 21 under the action of centrifugal force and washes the interior of the lint filter, and then flows upward along the inclined tub wall and is discharged through the water discharge opening.
In this embodiment, the rotational speed of the washing tub is increased, the generated centrifugal force overcomes the damping of the elastic member to cause the elastic member to generate compression deformation, the filter cover compresses and concentrates the thread scraps enriched in the filter, and meanwhile, the filter cover 2 seals the second flow passage and cuts off the first flow passage from the bottom, so that the water in the washing tub washes the thread scraps filter outwards through the filter opening of the filter cover. When the elastic piece compresses tightly, the filter cover compresses and collects the thread scraps and dirt in the filter, at the moment, the operation of pumping water into the filter is not executed when the filter cover cuts the bottom end of the first flow channel, the water in the washing barrel is also flushed inside the filter through the filter opening under the action of centrifugal force, and the upper water outlet is controlled to be opened by the washing machine, so that the thread scraps and dirt collected together are flushed to the water outlet and discharged out of the machine.
Other embodiments of this example are the same as example 1.
