Example one
As shown in fig. 1-2, a lint filtering device for a washing machine comprises a filtering and collecting chamber 400 for filtering and collecting lint, wherein the filtering and collecting chamber 400 has a first opening 101 and a second opening 102, an energy conversion mechanism 301 is arranged in the filtering and collecting chamber 400, water passes through the energy conversion mechanism 301 in the process of flowing from the first opening 101/the second opening 102 to the second opening 102/the first opening 101, the energy conversion mechanism 301 operates under the action of the water, the flow rate of the water is reduced, the capability of bearing the lint is reduced, and the lint is lowered to the bottom of the filtering and collecting chamber 400 under the action of gravity.
Generally, the washing machine comprises a pulsator, and when the pulsator rotates forwards, water flow enters from a first opening 101, passes through an energy conversion mechanism 301 and is discharged from a second opening 102; when the impeller rotates reversely, water flow enters from the second opening 102, passes through the transducer mechanism 301 and is discharged from the first opening 101.
When the speed of rivers is great, the thread scraps weight that can carry is great, if the speed of rivers reduces, then can reduce the carrying capacity of rivers, make the thread scraps sink and fall under the weight effect, collect chamber 400 through filtering and set up transducing mechanism 301, rivers are when passing through transducing mechanism 301, transducing mechanism 301 operates under the drive of rivers (if turn into transducing mechanism 301's kinetic energy, potential energy etc.), make the velocity of flow of rivers reduce, the kinetic energy of rivers reduces, the kinetic energy of rivers turns into transducing mechanism 301's energy (if turn into transducing mechanism 301's kinetic energy, potential energy etc.), the ability that rivers carried the thread scraps reduces, the thread scraps sinks and falls the bottom of filtering collection chamber 400 under the effect of gravity, the water after the separation passes transducing mechanism 301, realize the separation of thread scraps and water.
Further, the energy conversion mechanism 301 is a rotation mechanism, and the rotation mechanism 301 rotates under the action of the water flow, so that the flow rate of the water flow is reduced.
When the energy conversion mechanism 301 is a rotating mechanism, the rotating mechanism rotates (converted into kinetic energy) or swings (converted into kinetic energy and potential energy), so as to achieve the purpose of reducing the flow rate of water flow.
Further, the rotating mechanism comprises at least one rotating wheel 301, the rotating wheel 301 comprises a body 302 and blades 303 arranged on the body 302, the rotating wheel 301 is rotatably arranged on the inner wall of the filtering and collecting cavity 400, water flow entering the filtering and collecting cavity 400 from the first opening 101/the second opening 102 collides with the body 302 and/or the blades 303 of the rotating wheel 301, the rotating wheel 301 rotates under the action of the water flow, the flow speed of the water flow is reduced, and the kinetic energy of the water flow is partially converted into the rotational kinetic energy of the rotating wheel 301, so that the kinetic energy of the water flow is reduced.
The body 302 is a cylinder with a central hole 304 in the center and the blades 303 arranged around the side walls of the cylinder.
Wherein, the blades 303 can be perpendicular to the side wall of the cylinder or can be obliquely arranged.
The water flow collides with the body 302 of the rotating wheel 301 to drive the rotating wheel 301 to rotate, or the water flow collides with the blades 303 of the rotating wheel 301 to drive the blades 303 to drive the rotating wheel 301 to move, so that the flow velocity of the water flow is reduced, and the kinetic energy of the water flow is converted into the kinetic energy of the rotation of the rotating wheel 301.
The water flow entering through the first opening 101 and passing through the transducer 301 and then exiting through the second opening 102 will be explained as an example.
As shown in fig. 2, the inner wall of the filtering and collecting cavity 400 is provided with the mounting post 106, the mounting post 106 penetrates through the central hole 304 to sleeve the rotating wheel 301 on the mounting post 106, so that the rotating wheel 301 is rotatably arranged on the inner wall of the filtering and collecting cavity 400, water flow entering the filtering and collecting cavity 400 from the first opening 101 impinges on the body 302 of the rotating wheel 301 or impinges on the blades 303, so that the rotating wheel 301 rotates to reduce the flow velocity of the water flow, the thread scraps heavier than the water settle to the bottom of the filtering and collecting cavity 400 to realize the separation and collection of the thread scraps, and the water passes through the blades 303 and then is discharged from the second opening 102.
The rotating mechanism is set as the rotating wheel 301, and the rotation of the rotating wheel 301 has continuity, so that the reduction of the flow velocity of water flow is not too violent, water is not easy to splash, and the settling effect of thread scraps is better.
The rotating mechanism comprises a plurality of rotating wheels 301 or only one rotating wheel 301, but when the rotating mechanism comprises one rotating wheel 301, the water flow entering the filtering and collecting cavity 400 from the first opening 101 and/or the second opening 102 impinges on the rotating wheel 301 to rotate the rotating wheel 301, so that the flow rate of the water flow is reduced, the structure can achieve the purpose of reducing the flow rate of the water flow to settle the lint, but because the number of the rotating wheels 301 is small, the reduction range is limited, and the settling effect is limited. The rotating wheels are spaced, and are not easy to block in the rotating state.
Example two
As shown in fig. 1-2, in this embodiment, as a further limitation to the first embodiment, the rotating mechanism includes a plurality of rotating wheels 301, and drives the plurality of rotating wheels 301 to rotate, so as to reduce the flow velocity of the water flow, and compared with the arrangement of one rotating wheel 301, the reduction range of the flow velocity of the water flow is large, and the sedimentation effect is good.
Further, a plurality of rotating wheels 301 are meshed with each other to form a rotating wheel set 301, at least one rotating wheel 301 in the rotating wheel set 301 is opposite to the first opening 101 and/or the second opening 102, water flow entering the filtering and collecting cavity 400 from the first opening 101 and/or the second opening 102 collides with blades 303 of the rotating wheel 301, so that the rotating wheel 301 rotates and drives other rotating wheels 301 meshed with the rotating wheel to rotate, the rotating wheel set 301 rotates under the driving of the water flow, the flow speed of the water flow is reduced, thread scraps are settled under the action of gravity, and water passes through gaps among the rotating wheel sets 301.
Wherein, a part of the runners 301 in the runner set 301 is opposite to the first opening 101 and/or the second opening 102, and the water flow entering from the first opening 101 and/or the second opening 102 drives the part of the runners 301 to rotate, thereby driving the other runners 301 to rotate, or all the runners 301 in the runner set 301 may be opposite to the first opening 101 and/or the second opening 102, and the water flow entering from the first opening 101 and/or the second opening 102 drives all the runners 301 to rotate.
In the first scheme, a part of the runner 301 in the runner set 301 is opposite to the first opening 101 and/or the second opening 102. The water flow enters the runner set 301 from the first opening 101 and then is discharged from the second opening 102, and one runner 301 in the runner set 301 is opposite to the first opening 101.
By arranging the rotating mechanism with the rotating wheel set 301 formed by mutually meshing a plurality of rotating wheels 301, when the water flow entering from the first opening 101 collides with one of the rotating wheels 301, the rotating wheel 301 is driven to rotate, and because the other rotating wheels 301 are meshed with the rotating wheel 301, the rotating wheel 301 moves to drive the other rotating wheels 301 meshed with the rotating wheel 301 to move. Through the motion of a runner 301 drive other runners 301 motion, on the one hand, drive runner group 301 rotates required power great, and the range that water velocity reduces is big, and it is better to subside the effect, and on the other hand, the rotation of runner group 301 has the continuity, further reduces the probability that rivers bounce-back, makes the settlement effect of thread scraps better.
In the second scheme, all the rotating wheels 301 in the rotating wheel set 301 are opposite to the first opening 101 and/or the second opening 102, each rotating wheel 301 in the rotating wheel set 301 is opposite to the first opening 101 and/or the second opening 102, and water flow entering from the first opening 101 and/or the second opening 102 collides with each rotating wheel 301 to drive all the rotating wheels 301 to rotate, so that the rotation of the plurality of rotating wheels 301 is driven, the flow rate of the water flow is reduced, and the sedimentation effect is better.
Both of the above two schemes can achieve a large reduction in the magnitude of the water flow velocity.
Further, the plurality of rotating wheels 301 in the rotating wheel set 301 are arranged in a coplanar manner, the rotating plane of the rotating wheel set 301 is coplanar with the first opening 101 and/or the second opening 102, that is, the first opening 101 and/or the second opening 102 are opposite to the blade 303 of the rotating wheel 301 in the rotating wheel set 301, when water flow enters the filtering and collecting cavity 400 from the first opening 101 or the second opening 102 and collides with the blade 303, the blade 303 is driven to move to drive the rotating wheel 301 connected with the blade 303 to rotate, if the rotating wheel 301 is meshed with other rotating wheels 301, the rotation is transmitted to the other rotating wheels 301, so that the other rotating wheels 301 rotate, and the flow rate of the water flow is reduced by the resistance of the other rotating wheels 301. The runner 301 is easier to rotate due to the collision of water flow and the blades, so that the possibility of splashing is reduced, and the sedimentation effect is better.
The wheels 301 in the wheel set 301 may not be coplanar, as long as the above process can be implemented.
Further, the outer peripheral surface formed by the plurality of rotating wheels 301 in the rotating wheel set 301 is spaced from the first opening 101 and/or the second opening 102 by a certain distance, and the outer peripheral edge of the rotating wheel set 301 is larger than the first opening 101 and/or the second opening 102, so that the water flow entering the filtering and collecting cavity 400 from the first opening 101/the second opening 102 collides with the rotating wheel set 301, the water flow is prevented from directly passing through the rotating wheel set 301, and the structure improves the thread scraps settling effect. The outer peripheral surface may be a surface formed by the blades 303 of the plurality of runners 301 meshing with each other, or may be a surface formed by the bodies 302 and the blades 303 of the plurality of runners 301.
Further, all the runners 301 in the runner group 301 are disposed in a coplanar manner, the first opening 101 and/or the second opening 102 are disposed in a coplanar manner with the rotation plane of the runner group 301, that is, the first opening 101 and/or the second opening 102 are opposite to the blades 303 of the runners 301 in the runner group 301, and the periphery of the outer peripheral surface of the runner group 301 (i.e., the surface formed by the engagement of the blades 303 of the plurality of runners 301) is larger than the first opening 101 and/or the second opening 102.
Preferably, the outer circumferential edge of the pulley block 301 is larger than the first opening 101 and the second opening 102. On the one hand, rivers that first opening 101 or second opening 102 got into are direct to collide with blade 303, and drive runner 301 rotates, and the velocity of flow of rivers reduces faster, the range is bigger, and on the other hand, overlap joint prevents between blade 303 that rivers do not pass runner group 301 and diameter, can not realize the function that the thread scraps subsides, influences the thread scraps and subsides the effect.
Further, all the rotating wheels 301 in the rotating wheel set 301 are arranged in the same plane in a collinear manner, the adjacent rotating wheels 301 are meshed with each other to form a long strip-shaped rotating wheel set 301, the first opening 101 and/or the second opening 102 are opposite to the long axis direction of the rotating wheel set 301, and therefore the water flow entering from the first opening 101 or the second opening 102 can be completely converted with the rotating wheel set 301.
The rotating mechanism comprises a plurality of rotating wheels 301, the plurality of rotating wheels 301 can be arranged at intervals, the periphery of each rotating wheel 301 is opposite to the first opening 101 and/or the second opening 102, water flow entering the filtering and collecting cavity 400 from the first opening 101 or the second opening 102 strikes the blades 303 of each rotating wheel 301, the rotating wheels 301 are driven to rotate, the flow speed of the water flow is reduced, line scraps are settled under the action of gravity, and water passes through the rotating wheels 301. Although this structure also can realize the rotation of drive runner 301 and reduce the purpose of rivers velocity of flow, but there is not interact force between runner 301, and the range that reduces is little, and the line bits subsides the effect poor, exists the clearance between blade 303 moreover, if the clearance is too big, rivers can directly pass through from between blade 303, and this part rivers can not the deceleration, can't make the line bits subside under the weight effect, can realize filtering and collect, but the effect is not good.
