Description

Technical Field

[0001] The invention belongs to the field of washing equipment, and in particular relates to a pulsator with a lint filtering function and a pulsator washing machine. Background Art

[0002] As people's living standards continue to improve, washing machines have gradually become one of the essential household appliances in people's homes. A pulsator washing machine includes an outer barrel arranged in a housing, an inner barrel rotatably arranged in the outer barrel, and a pulsator rotatably arranged at the bottom of the inner barrel. When washing with a pulsator washing machine, the rotation of the pulsator drives the flow of clothes and water to wash the clothes. However, when washing clothes with a pulsator washing machine, if there are a lot of clothes, the clothes are not turned over well, and problems such as clothes entanglement, wrinkles, poor washing, and weak water flow often occur, thereby affecting the washing effect and making it difficult to meet the user's laundry needs.

[0003] In order to solve the above problems, a Chinese patent with application number CN200820083603.2 discloses an inverted T-shaped pump-type water flow impeller. There is a cylindrical body in the center of the impeller, with a hole inside that leads to the bottom of the impeller, a waterfall outlet hole is provided at the top of the cylindrical body, and there are several washing ribs on the surface of the cylinder: there are spiral water stirring blades at the bottom of the impeller disc, and the water is sent to the top of the cylinder through the central hole of the cylinder by the rotational force of the impeller to form a fountain-like waterfall. Two waterfalls can be formed in the center and on the wall of the washing barrel by the forward and reverse rotation of the impeller. This solution can enhance the water flow, reduce entanglement, and improve the washing ratio of clothes, but it is necessary to add an additional power mechanism to send the water flow into the cylindrical body, which is costly, and the anti-entanglement ability of clothes needs to be improved. It is also necessary to solve the problem of wire scrap filtering during washing, usually a detachable wire scrap filter is set on the inner wall of the inner barrel. The lint filter is generally set at a certain height of the inner barrel. The impeller drives the water to flow circumferentially in the inner barrel and filter it through the lint filter. The filtering effect is limited, especially when the water level for washing is low, the filtering effect needs to be improved.

[0004] In view of this, the present invention is proposed. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art. The purpose is to provide a pulsator with a lint filtering function.

The lint filter is arranged in the rotating part. When washing clothes, the pulsator rotates, driving the water flow and clothes in the washing tub to rotate. The rotating part rotates driven by the clothes, which can prevent the clothes from being entangled in the middle and promote the stretching of the clothes. It can also play a role in improving the washing ratio and rinsing ability of the clothes. The washing water is filtered by the lint filter and then discharged to the lower side of the pulsator, which can also filter the lint and improve the lint collection efficiency.

[0016] Furthermore, there is a certain gap between the portion of the lint filter extending into the accommodating space and the inner peripheral wall of the accommodating space, and the outer diameter gradually decreases from the opening end to the other end.

[0017] Further, the rotating member is a rotating cylinder, the supporting frame is a supporting cylinder with openings at both ends, the opening of the rotating cylinder is rotatably sleeved on the outer peripheral wall of the supporting cylinder with the opening facing downward, and the water inlet is arranged at the top of the rotating cylinder and is a plurality of water-permeable holes;

DETAILED DESCRIPTION

[0049] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0050] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “vertical”, “inside” and “outside” are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0051] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0052] like Figures 1 to 14 As shown, the present invention provides a washing machine impeller with a lint filtering function, by arranging the impeller in the inner barrel of the washing machine so as to be rotatable forwards and backwards, and driving the water flow through the impeller to drive the clothes in the inner barrel to turn over for washing.

[0053] The washing machine pulsator comprises a pulsator disc 1 , a support frame 2 , a rotating member 3 and a lint filter 4 .

[0054] The support frame 2 is protruding upward and arranged in the middle of the impeller 1. The support frame 2 has a receiving space 23 inside, which is connected to the lower side of the impeller 1. The rotating member 3 has a cavity 315 connected to the opening inside, and is freely rotatable in forward and reverse directions and sleeved on the outer periphery of the support frame 2. The cavity 315 is provided with a water inlet.

[0055] The lint filter 4 is disposed in the cavity 315 of the rotating member 3 , and is connected between the water inlet of the rotating member 3 and the outlet of the accommodating space 23 .

[0056] The washing machine impeller of the present invention is provided with a protruding support frame 2 in the middle of the impeller disc 1, and a rotating member 3 is sleeved on the outer periphery of the supporting frame 2 so as to be freely rotatable in both directions. When washing clothes, the impeller rotates, driving the water flow and clothes in the washing tub to rotate. The rotating member 3 rotates driven by the clothes, which can prevent the clothes from being entangled in the middle, promote the stretching of clothes, reduce the entanglement of clothes during the washing process, and also play a role in improving the washing ratio and rinsing ability of the clothes.

[0057] The present invention further provides a lint filter 4 in the cavity 315 of the rotating part 3, and the lint filter 4 is respectively connected with the cavity 315 of the rotating part 3 and the accommodating space 23 of the support frame 2. The washing water enters the lint filter 4 through the water inlet of the rotating part 3 and the lint is intercepted, and the filtered washing water is discharged from the accommodating space 23 of the support frame 2 to the lower side of the impeller 1. The centrifugal force generated by the rotation of the impeller 1 drives the washing water on the lower side to the outer periphery of the impeller 1 and then enters the inner barrel for washing, forming a quasi-vacuum state at the bottom of the impeller, so that a large amount of washing water passes through the rotating part 3 and the lint filter 4 and then enters the bottom of the impeller, which can not only avoid the entanglement of clothes and improve the washing effect of clothes, but also filter the lint and improve the lint collection efficiency. It has a compact structure, diverse functions and low cost.

[0058] The pulsator disc 1 and the accommodating space 23 are connected vertically, so that the accommodating space 23 is connected to the lower side of the pulsator disc 1. The lint filter 4 can be arranged in the rotating member 3 above the support frame 2, or part of it can be above the support frame 2 and part of it can extend into the support frame 2.

[0059] like Figures 2 to 8 As shown, a reversing structure is provided on the rotating member 3 and the support frame 2. The rotating member 3 is supported on the outer peripheral wall of the support frame 2 in a forward and reverse rotation manner through the reversing structure, and the rotational motion of the rotating member 3 is converted into an up and down movement relative to the support frame 2. The lint filter 4 is fixed on the rotating member 3 and is arranged to be movable up and down relative to the support frame 2 along with the rotating member 3.

[0060] In the present invention, the rotating member 3 is sleeved on the support frame 2 so as to be rotatable in both directions through the reversing structure, so that the rotating member 3 can be arranged on the support frame 2 to be movable up and down. During the washing process of the pulsator, the water flow drives the clothes to turn over, and the rotating member 3 rotates driven by the clothes and can move up and down on the support frame 2. The movement of the rotating member 3 can cooperate with the water flow to promote the turning of the clothes, improve the flushing force of the water flow, and further improve the anti-entanglement ability, washing ability and rinsing ability of the clothes. The lint filter 4 is fixed on the rotating member 3, and moves up and down with the rotation of the rotating member 3, driving the water flow and lint flow inside the lint filter 4, which can improve the water flow discharge speed in the lint filter 4 and accelerate the lint collection efficiency.

[0061] Figure 2 The figure is the lowest point where the rotating member 3 rotates on the support frame 2. For example, when the impeller rotates in the forward direction, it drives the water flow to flow, thereby driving the clothes to move in the forward direction and spirally, and the clothes drive the rotating member 3 to rotate in the forward direction on the support frame 2 and move downward relative to the support frame 2; when the impeller rotates in the reverse direction, it drives the water flow to flow, thereby driving the clothes to move in the reverse direction and spirally, and the clothes drive the rotating member 3 to rotate in the reverse direction on the support frame 2 and move upward relative to the support frame 2. It can also be set that when rotating in the forward direction, the rotating member 3 moves upward relative to the support frame 2.

[0062] Usually, when the impeller drives the water flow, the water flow will turn upside down from the outer circumference to the inner circumference, or turn upside down from the inner circumference to the outer circumference, and flow in a spiral along the circumference. The lifting direction corresponding to the positive and reverse rotation of the rotating member 3 can be specifically determined and set according to the turning direction of the clothes.

[0063] Preferably, the reversing structure is a thread, and the rotating member 3 is supported on the support frame 2 so as to be rotatable in forward and reverse directions and movable up and down through the thread.

[0064] One end of the lint filter 4 has an opening, and the outer peripheral edge of the opening end is mounted on the inner peripheral wall of the cavity 315 outside the support frame 2, which can block the lint in the washing water entering the rotating member 3 from the water inlet. Preferably, the other end of the lint filter 4 is recessed downward and extends into the accommodating space 23 of the support frame 2. The lint filter 4 is recessed downward so that it has a large enough space for filtering and accommodating lint, so as to avoid affecting the filtering efficiency when a lot of lint accumulates.

[0065] There is a certain gap between the portion of the lint filter 4 extending into the accommodating space 23 and the inner peripheral wall of the accommodating space 23 , and the outer diameter gradually decreases from the open end to the other end.

[0066] The rotating member 3 is a rotating cylinder 31, and the supporting frame 2 is a supporting cylinder 21 with openings at both ends. The opening of the rotating cylinder 31 is rotatably sleeved on the outer peripheral wall of the supporting cylinder 21 with the opening facing downward. The water inlet is arranged at the top of the rotating cylinder 31, and is a plurality of water permeable holes 314.

[0067] The impeller disc 1 in the support cylinder 21 is provided with an impeller through hole 12 and a water leakage hole 14. The water leakage hole 14 is provided on the impeller disc 1 outside the impeller through hole 12 and is provided through the upper and lower sides of the impeller. The impeller disc 1 outside the support cylinder 21 is a non-porous structure. The water permeable hole 314, the wire scrap filter 4, the water leakage hole 14, and the lower side of the impeller sequentially form a filtering channel. The impeller through hole 12 is used to install the impeller shaft to drive the impeller to rotate.

[0068] The present invention sets a leakage hole 14 on the impeller 1 in the supporting cylinder 21, and sets the impeller 1 outside the supporting cylinder 21 as a non-porous structure. Therefore, washing water can only enter from the water permeable hole 314 of the rotating part 3 at the top of the impeller 1, and flow into the lint filter 4 extended into the supporting cylinder for filtration. The filtered washing water enters the lower side of the impeller through the lower end opening of the supporting cylinder and the leakage hole 14, and returns to the inner barrel through the gap between the outer peripheral edge of the impeller and the inner barrel under the action of centrifugal force. Since no other leakage holes 14 are set on the impeller 1, the washing water will enter the rotating part 3 again for filtration, and the cycle is repeated, which can filter the lint well and further improve the filament filtering efficiency.

[0069] Preferably, the water permeability area of ​​the water permeable hole 314 is smaller than the water leakage area of ​​the water leakage hole 14 .

[0070] Furthermore, there is a certain gap between the other end of the lint filter 4 and the impeller 1 in the support frame 2, which can prevent the outer wall of the lint filter 4 and the inner wall of the support frame 2 from interfering with and wearing each other when the rotating member 3 drives the lint filter 4 to rotate.

[0071] When the rotating part 3 is located at the lowest point on the support frame 2, the other end of the lint filter 4 is arranged close to the impeller through hole 12, which can also prevent the rotating part 3 from driving the lint filter 4 to move up and down and interfere with the impeller 1, causing wear or collision damage.

[0072] The vertical extension length of the lint filter 4 is greater than the vertical movement distance of the rotating member 3 .

[0073] like Figures 5 to 8 As shown, the lint filter 4 includes a mounting structure 41 and a filtering structure 42 .

[0074] The mounting structure 41 is cylindrical, one end of which is mounted on the inner peripheral wall of the cavity 315 between the support frame 2 and the water inlet, and the other end of which extends into the accommodation space 23 of the support frame 2. The filter structure 42 is provided with a filter hole 421 for filtering the lint in the washing water. One end of the filter structure 42 is connected to the other end opening of the mounting structure 41, and the other end of the filter structure 42 extends into the support frame 2.

[0075] The lint filter 4 of the present invention is provided with a connected mounting structure 41 and a filtering structure 42. It can be fixed on the inner wall of the rotating part 3 through the mounting structure 41 to support the filtering structure 42, and the mounting structure 41 and the filtering structure 42 can be extended into the supporting tube to save space and increase the filtering space, thereby improving the filtering efficiency.

[0076] Preferably, the outer diameter of the mounting structure 41 is gradually reduced from one end to the other end. The filter structure 42 is a filter sleeve, one end of which is an opening connected to the other end of the mounting structure 41, and the other end of which extends downward and has an outer diameter gradually reduced. The filter sleeve is a soft mesh structure.

[0077] Specifically, the rotating drum 31 includes a detachably connected annular drum body 311 and a drum cover 312. The drum cover 312 can be used to decorate and protect clothes from wear. The inner peripheral edge of the upper end opening of the annular drum body 311 is provided with an annular cavity 3111 that is concave downward.

[0078] The mounting structure 41 includes a mounting cylinder 411 and a flange 412. The mounting cylinder 411 extends from the upper end to the lower end, and the outer diameter gradually decreases. The flange 412 is formed by folding outward from the upper end opening of the mounting cylinder 411 and is located above the supporting cylinder 21. The flange 412 is installed in the annular cavity 3111, and the lower end of the mounting cylinder 411 and the filter structure 42 extend into the accommodating space 23. The cylinder cover 312 is installed in the annular cavity 3111.

[0079] The vertical extension length of the filter sleeve is greater than the vertical extension length of the mounting tube 411 .

[0080] When the rotating member 3 rotates to the lowest point on the support cylinder, the upper end of the annular cylinder 311 protrudes upward from the support cylinder 21 , and the bottom wall of the annular cavity 3111 is located above the upper end opening of the support cylinder 21 .

[0081] Preferably, an extension plate protruding upward is provided at the upper opening edge of the mounting tube 411 and extending at intervals along the circumferential direction. The annular insert edge 3121 extends into between the inner circumferential wall of the annular cavity 3111 and the extension plate.

[0082] A limiting groove is provided on the inner peripheral wall of the annular cavity 3111 , and a clamping claw is provided on the outer peripheral wall of the annular insert edge 3121 , which is clamped and connected with the limiting groove.

[0083] The annular insert edge 3121 is arranged on the inner ring side of the outer peripheral edge of the cylinder cover 312, and protrudes downward from the lower end surface of the outer peripheral wall of the cylinder cover 312. The lower end surface of the outer peripheral wall of the cylinder cover 312 presses against the end surface of the opening outer periphery of the annular cylinder body 311, and the annular insert edge 3121 abuts against the bottom wall of the annular concave cavity 3111.

[0084] like Figures 9 to 14 As shown, the impeller 1 is provided with a protruding water-displacing blade 11, the support frame 2 protrudes upward from the water-displacing blade 11, the rotating member 3 is sleeved on the middle and upper part of the support frame 2, and the bottom of the rotating member 3 is higher than the top of the water-displacing blade 11.

[0085] The present invention makes the upward protrusion height of the support frame 2 higher than the height of the water-repelling blade 11, and the rotating member 3 is sleeved on the middle and upper part of the support frame 2 and higher than the top of the water-repelling blade 11, so that the rotating member 3 can have a larger vertical movable range, thereby improving the turning effect of the water flow and clothes, improving the flushing intensity of the water flow, and also avoiding the clothes from being caught between the rotating member 3 and the water-repelling blade 11.

[0086] Preferably, the impeller 1 is gradually concave from the outer circumference to the middle, and the water-dispelling blade 11 extends from the outer peripheral edge of the impeller 1 to the inner ring side until it is connected to the support frame 2. The top of the water-dispelling blade 11 protrudes from the outer peripheral edge of the impeller 1, and the protruding height of the support frame 2 is much higher than the height of the water-dispelling blade 11. The protruding extension length of the rotating member 3 is less than the protruding extension length of the support frame 2.

[0087] A plurality of water-dispelling blades 11 are circumferentially spaced apart and arranged on the top wall of the impeller 1. Preferably, the impeller 1 is provided with 2-4 water-dispelling blades 11.

[0088] More preferably, the protruding extension length of the support frame 2 is 2-5 times the protruding extension length of the water-repelling blade 11 .

[0089] The present invention facilitates the turning of clothes by gradually concavely arranging the impeller 1 from the outer circumference to the middle, and easily forms a vortex water flow, thereby improving the washing ratio of clothes. In addition, the concave arrangement of the impeller 1 can increase the washing volume in the inner barrel, and can also prevent foreign matter from entering the inner barrel bottom through the gap between the edge of the impeller and the inner barrel bottom. The water-repelling blade 11 extends from the outer peripheral edge of the impeller 1 to the inner ring side to connect with the support frame 2, which can avoid leaving a gap between the water-repelling blade 11 and the support frame 2 to prevent clothes from being clamped. The top of the water-repelling blade 11 protrudes from the outer peripheral edge of the impeller 1, and can also ensure the effect of the water-repelling blade 11 in driving the water flow.

[0090] Furthermore, the reversing structure includes a first thread 211 and a second thread 313. The outer peripheral wall of the support frame 2 is provided with a first thread 211 in the up-down direction, and the inner peripheral wall of the cavity 315 of the rotating member 3 is provided with a matching second thread 313. The rotating member 3 is supported on the support frame 2 by the thread so as to be rotatable in both directions and movable up and down.

[0091] The number of thread turns of the first thread 211 is greater than the number of thread turns of the second thread 313 , and the first thread 211 is arranged at the upper middle portion of the support frame 2 .

[0092] The first thread 211 and the second thread 313 are arranged spirally upward. The first thread 211 may be a female thread and the second thread 313 may be a male thread; or the first thread 211 may be a male thread and the second thread 313 may be a female thread.

[0093] Preferably, the first thread 211 is recessed in the middle and upper part of the outer peripheral wall of the support frame 2 , and the second thread 313 is protruding on the inner peripheral wall of the cavity 315 of the rotating member 3 .

[0094] Furthermore, the outer peripheral wall of the rotating member 3 is provided with a protruding rotating blade 32, which is extended in the up-down direction. The protruding height of the lower part of the rotating blade 32 is greater than the protruding height of the upper part of the rotating blade 32, so that when the rotating member 3 rotates, a larger water flow can be generated at the lower part of the rotating member 3, and the turning of the water flow is conducive to the turning and washing of the clothes.

[0095] During the washing or rinsing process of the washing machine, the rotation of the impeller drives the water flow and the clothes to turn over, and the clothes drive the rotating member 3 to rotate. Since the protruding height of the lower part of the rotating blade 32 is greater than the protruding height of the upper part of the rotating blade 32, the rotating blade 32 can be moved at the lower part of the rotating member 3 to generate a larger water flow, which is conducive to the turning of the water flow and clothes in the inner barrel, and the rotating member 3 also moves up and down while rotating, so that the rotating blade 32 rotates up and down, which can drive the water flow to flow up and down, and cooperate with the turning water flow in the inner barrel, which can further promote the turning of clothes and prevent the clothes from being entangled, and further improve the washing and rinsing performance. In addition, the rotating blade 32 is protruding from the outer peripheral wall of the rotating member 3, which can make the maximum radial size of the rotating member 3 larger, so that when the clothes are turned over, they can be as far away from the middle of the impeller disc 1 as possible, and turn over between the rotating member 3 and the inner peripheral wall of the inner barrel, so as to prevent entanglement and improve the turning effect.

[0096] Preferably, the protruding ends of the rotating blades 32 are vertically extended in a wave shape to form a plurality of protruding plates connected in sequence, and the heights of the plurality of protruding plates gradually decrease from bottom to top.

[0097] A plurality of rotating blades 32 are arranged at intervals along the circumferential direction on the outer peripheral wall of the rotating member 3, and reinforcing ribs 33 are connected between adjacent rotating blades 32, which can enhance the connection strength of the rotating member 3 and enable the clothes to be turned over better when the rotating member 3 moves up and down.

[0098] Preferably, the reinforcing rib 33 is extended and arranged on the outer peripheral wall of the middle part of the rotating member 3 .

[0101] Preferably, an annular boss 13 is provided in the middle of the impeller disc 1, a concave cavity 131 is provided on the top of the annular boss 13, and the impeller through hole 12 is arranged at the bottom of the concave cavity 131. A slot 132 is also provided on the inner peripheral edge of the bottom wall of the concave cavity 131, and the lower end of the support cylinder 21 is installed in the concave cavity 131 and is arranged in close contact with the inner peripheral wall of the concave cavity 131.

[0102] The impeller disc 1 is gradually concave from the outer periphery and extends to the annular boss 13, and is connected to the outer peripheral wall of the support cylinder 21. The top of the annular boss 13 is flush with the outer peripheral edge of the impeller disc 1.
