[0002] With the improvement of living standards, washing machines have entered thousands of households. Washing machines are generally divided into two categories, namely, pulsator washing machines and drum washing machines. Among them, pulsator washing machines are generally composed of a box, a frame, a drum, a pulsator and a transmission system. The frame is set on the top of the box, which is mainly used to fix and install control components, such as circuit boards, power switches, micro switches and water inlet valves.

[0003] During the washing process, a pulsator washing machine will wash off impurities such as lint attached to clothes. The lint impurities washed off are usually collected by a filter installed in the drum of the pulsator washing machine. The filter has filter holes on the side facing the inner drum. After the washing water enters the filter with the lint, the lint is retained in the filter, and the remaining washing water flows back into the drum from the filter holes. However, this type of filter has a single path for the washing water to flow back to the inner drum and a low circulation rate, resulting in poor filtration effect and a large amount of lint left behind, which can easily cause customer dissatisfaction.

DETAILED DESCRIPTION

[0034] In order to make the purpose and implementation method of the present application clearer, the exemplary implementation method of the present application will be clearly and completely described below in conjunction with the drawings in the exemplary embodiments of the present application. Obviously, the described exemplary embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0035] It should be noted that the brief description of terms in this application is only for the convenience of understanding the embodiments described below, and is not intended to limit the embodiments of this application. Unless otherwise specified, these terms should be understood according to their ordinary and common meanings.

[0036] The terms "first", "second", "third", etc. in the specification and claims of this application and the above drawings are used to distinguish similar or similar objects or entities, and do not necessarily mean to limit a specific order or sequence, unless otherwise noted. It should be understood that the terms used in this way can be interchangeable under appropriate circumstances.

[0037] The terms "including" and "having" and any variations thereof are intended to cover but not exclude inclusion, for example, a product or device comprising a list of components is not necessarily limited to all the components expressly listed but may include other components not expressly listed or inherent to such product or device.

[0038] When washing clothes, the pulsator washing machine will wash away impurities such as lint attached to the clothes. The lint impurities washed away are usually collected by a filter installed in the drum of the pulsator washing machine. The filter has a filter hole on the side facing the inner drum. After the washing water enters the filter with the lint, the lint is retained in the filter, and the remaining washing water flows back into the drum from the filter hole. However, this filter has a single path for the washing water to flow back to the inner drum, and the circulation speed is low, resulting in poor lint filtering effect, a large amount of lint is left, and it is easy to cause customer dissatisfaction. To solve this problem, the present application proposes a pulsator washing machine.

[0039] See also Figures 1 to 4 A pulsator washing machine includes a housing (not shown in the drawings), a drum, a water channel cover plate 3 and a filter chamber. The housing can be the overall structure of the washing machine. The housing is a hollow structure in which other components of the washing machine can be arranged, such as a circuit structure, a driving mechanism and a drainage structure. The housing can be in the shape of a hollow cuboid or a hollow cylinder, and is not limited to the above shapes.

[0040] The drum is arranged in the box body and is used for washing clothes. The drum body has a washing cavity. Clothes are put into the washing cavity through the clothes feeding port provided on the drum body for washing. Correspondingly, a door body is arranged on the box body, and the door body is arranged corresponding to the clothes feeding port. The door body is used to close the clothes feeding port of the drum body when washing clothes, so that the washing cavity is a closed space when washing clothes. A door glass can also be arranged on the door body to facilitate observation of the washing process.

[0041] The drum body may include an outer drum 1 and an inner drum 2, the inner drum 2 is hollow to form a washing chamber, the inner drum 2 is arranged in the outer drum 1, the outer drum 1 is arranged in the box, the axial direction of the inner drum 2 and the outer drum 1 is arranged along the vertical direction, a water containing chamber 21 for containing washing water is provided between the inner peripheral wall of the outer drum 1 and the outer peripheral wall of the inner drum 2, and an opening is provided on the peripheral wall of the inner drum 2, the inner drum 2 is connected with the water containing chamber 21 through the opening, the inner drum 2 can discharge the washing water into the water containing chamber 21 through the opening, and the washing water is discharged from the washing machine through the drainage structure connected to the outer drum 1, and at the same time, the washing water in the water containing chamber 21 can also flow into the inner drum 2 through the opening to wash the clothes. The inner diameter of the opening is at least 4mm, and it is arranged in the form of a flip hole, which can avoid scratching the clothes while improving the water flow exchange efficiency of the inner and outer drums 1.

[0042] In some embodiments, a balancing ring is also connected to the top of the inner drum 2, and the balancing ring is used to improve the anti-eccentricity ability of the inner drum 2 during the dehydration process, thereby ensuring the smooth operation of the washing machine and improving the user experience.

[0043] In some embodiments, a pulsator 5 is rotatably provided at the bottom of the inner drum 2. There is a gap between the pulsator 5 and the bottom of the inner drum 2. The pulsator 5 rotates to stir the washing water in the inner drum 2 and drive the clothes to roll up and down to wash the clothes. Centrifugal force is generated during the rotation, causing the washing water to roll up and down.

[0044] The impeller 5 includes a wave disc and stirring ribs arranged on the wave disc. The wave disc is provided with a leakage hole 51. The leakage hole 51 is connected to the bottom of the inner drum 2. The bottom of the inner drum 2 is connected to the outer drum 1. In this embodiment, the flow rate of washing water between the inner and outer drums 1 can be increased by increasing the inner diameter of the leakage hole 51. The inner diameter of the leakage hole 51 is at least 4 mm, such as 4 mm or 5 mm.

[0045] In some embodiments, the water channel cover 3 covers the inner circumferential wall of the inner cylinder 2 and encloses an installation chamber therewith, the bottom of the installation chamber is connected to the bottom of the inner cylinder 2, and an installation port 36 is opened on the side of the installation chamber facing the center of the inner cylinder 2. The filter 4 is removably installed in the installation chamber through the installation port 36, so that the washing water entering the bottom of the inner cylinder 2 from the water leakage hole 51 of the impeller is rushed into the installation chamber driven by the centrifugal force of the rotation when the impeller 5 rotates, and enters the filter 4, and the impurities such as wire scraps are filtered out by the filter 4. After enough wire scraps and impurities are collected in the filter 4, it can be removed from the water channel cover 3 to facilitate the removal of the wire scraps for reuse.

[0046] See also Figures 5 to 8In this embodiment, the installation chamber includes a top wall, and a first side wall and a second side wall opposite to each other. The first side wall, the second side wall and the top wall are connected to the inner circumferential wall of the inner tube 2, so that a relatively sealed state is formed between the installation chamber and the inner circumferential wall of the inner tube 2. When the filter 4 is installed in the installation chamber, the filter 4 is surrounded by the first side wall, the second side wall and the top wall, and the filter 4 can be clamped in the installation chamber by reasonably designing the sizes of the two.

[0047] Among them, the filter 4 has a filter chamber 40, and a water inlet connected to the bottom of the inner drum 2 is provided at the bottom of the filter chamber 40. When the washing machine is running, the washing water containing lint first enters the installation chamber under the drive of the impeller 5, and then enters the filter chamber 40 through the water inlet, and the lint impurities on the clothes also enter the filter chamber 40.

[0048] Further, the filter chamber 40 has a first cavity wall 411 and a second cavity wall 421 opposite to each other. It is understandable that the filter chamber 40 may also have other cavity walls connected to the first cavity wall 411 and the second cavity wall 421, such as a top cavity wall, to form a complete filter chamber 40 together with the first cavity wall 411 and the second cavity wall 421. The first cavity wall 411 faces the inner peripheral wall of the inner cylinder 2, and the second cavity wall 421 faces the center direction of the inner cylinder 2. The first cavity wall 411 and the second cavity wall 421 are both provided with filter holes 44 for filtering washing water. The washing water in the filter chamber 40 can enter the inner cylinder 2 from the filter holes 44 on the second cavity wall 421, and the wire scraps are blocked by the filter holes 44 to remain in the filter chamber 40.

[0049] In this embodiment, a lateral flow channel 33 is formed between at least one of the first side wall and the second side wall and the inner peripheral wall of the inner drum 2. After the washing water is filtered through the filter holes 44 on the first cavity wall 411, it flows back to the inner drum 2 through the lateral flow channel 33, thereby increasing the flow rate of the washing water from the filter 4 to the inner drum 2, not limited to the path of only flowing back from the filter holes 44 on the second cavity wall 421 to the inner drum 2. By accelerating the flow rate of the washing water and reducing the water flow resistance in the filter 4, the washing water can flow faster, so that more washing water can enter and flow out of the filter 4 per unit time, and more lint can be entrained into the filter chamber 40, thereby improving the lint collection capacity of the filter 4 and increasing user satisfaction. It is understandable that the first side wall and the second side wall can form a lateral flow channel 33 with the inner peripheral wall of the inner drum 2, so that the washing water can flow out to the lateral flow channels 33 on both sides, further increasing the flow rate of the washing water.

[0050] Furthermore, the waterway cover plate 3 includes a cover plate body 31 and a mounting plate 32 disposed on the side of the cover plate body 31 facing the inner peripheral wall of the inner cylinder 2. The cover plate body 31 covers the inner peripheral wall of the inner cylinder 2, thereby forming a relative sealing effect therewith. The left and right sides of the cover plate body 31 can be bent toward the inner peripheral wall of the inner cylinder 2 to form a space between the inner peripheral wall of the inner cylinder 2, or the cover plate body 31 can be an arc-shaped plate as a whole with a protrusion in the middle, and the left and right sides of the cover plate body 31 are connected to the inner peripheral wall of the inner cylinder 2, and the space between the cover plate body 31 and the inner peripheral wall of the inner cylinder 2 forms an installation chamber. Positioning columns may be provided on the left and right sides of the bottom of the cover body 31, which is assembled to the bottom of the inner cylinder 2 through the positioning columns, and a snap-fit ​​structure may also be provided in the upper and middle part of the cover body 31 to be fixedly connected with the inner circumferential wall of the inner cylinder 2, and the bottom of the cover body 31 extends downward to the bottom of the inner cylinder 2, and is connected with the gap between the impeller 5 and the bottom of the inner cylinder 2. The washing water enters the installation chamber under the centrifugal action of the impeller 5, and ascends in the installation chamber, thereby entering the filter chamber 40 through the water inlet.

[0051] In some embodiments, two mounting plates 32 are provided, and the mounting plates 32 extend along the axial direction of the inner cylinder 2. The two mounting plates 32 are spaced apart along the circumference of the inner cylinder 2, and the two mounting plates 32 are connected to the inner circumferential wall of the inner cylinder 2. The inner side walls of the two mounting plates 32 respectively form the first side wall and the second side wall, that is, the space between the two mounting plates 32 constitutes the mounting chamber, and the lateral flow channel 33 is provided between the mounting plate 32 and the inner circumferential wall of the inner cylinder 2. The space between the mounting plate 32 and the side wall of the cover plate body 31 opposite to it forms a vertical channel 34, and the vertical channel 34 is connected to the bottom of the inner cylinder 2. In this way, the washing water flows back to the inner cylinder 2 through the lateral flow channel 33 and the vertical channel 34 in turn, thereby increasing the flow rate of the washing water while avoiding direct leakage from the side wall of the waterway cover plate 3 into the inner cylinder 2.

[0052] In some embodiments, a plurality of lateral flow channels 33 are provided at intervals at one end where the mounting plate 32 is connected to the inner circumferential wall of the inner drum 2, and between adjacent lateral flow channels 33 is the portion where the mounting plate 32 is connected to the inner circumferential wall of the inner drum 2, thereby enhancing the structural strength of the mounting plate 32 and the mounting chamber through this portion. By reasonably designing the size and arrangement number of the lateral flow channels 33, the requirements for both the structural strength of the mounting plate 32 and the flow rate of washing water can be taken into account.

[0053] In some embodiments, a plurality of stop ribs 35 inclined toward the bottom of the inner cylinder 2 are arranged in intervals in the vertical channel 34. The stop ribs 35 can be used to prevent the backflow of the wire scraps, so that the washing water mixed with the wire scraps enters the bottom of the installation chamber and is flushed into the filter chamber 40 again with the next wave of washing water. It is understandable that the inclination angle of the stop rib 35 should not be too large or too small, and is preferably between 15° and 75°.

[0054] Among them, a number of stop ribs 35 are staggered along the axial direction of the inner drum 2, thereby forming a labyrinth-shaped waterway, which better blocks the backflow of wire scraps and allows washing water to flow from top to bottom as much as possible. It can be understood that one end of some stop ribs 35 is connected to the mounting plate 32, and the other end has a gap with the corresponding side wall of the cover plate body 31, and one end of another stop rib 35 is connected to the side wall of the cover plate, and the other end has a gap with the corresponding mounting plate 32, so that washing water can flow through.

[0055] In some embodiments, a water outlet hole 22 connected to the water containing chamber 21 is provided at a position on the inner circumferential wall of the inner cylinder 2 opposite to the first cavity wall 411. The water outlet hole 22 penetrates the inner circumferential wall of the inner cylinder 2 to be connected to the water containing chamber 21. In this way, the washing water in the filter chamber 40 can also enter the water containing chamber 21 from the filter hole 44 of the first cavity wall 411 through the water outlet hole 22, and finally return to the inner cylinder 2 or be discharged. In this way, the water outlet path of the washing water in the filter 4 is increased, so that the washing water in the filter 4 can directly return to the inner cylinder 2 from the filter hole 44 on the second cavity wall 421 after being filtered, return to the bottom of the inner cylinder 2 from the lateral flow channel 33 through the vertical channel 34, and return to the bottom of the inner cylinder 2 from the filter hole 44 on the first cavity wall 411 and the water outlet hole 22 on the inner circumferential wall of the inner cylinder 2 to the water containing chamber 21, forming a three-way water outlet path, which greatly increases the washing water outlet area of ​​the filter 4, thereby increasing the washing water flow rate and improving the debris filtering effect.

[0056] In this embodiment, a plurality of water outlet holes are provided, and the plurality of water outlet holes are arranged at intervals on the inner peripheral wall of the inner cylinder 2, so that the flow rate of the washing water entering the water containing cavity 21 from the filter hole 44 of the first cavity wall 411 can be increased. At the same time, the plurality of water outlet holes are arranged at intervals, and there is still a solid structure of the inner peripheral wall of the inner cylinder 2 between adjacent water outlet holes, which has a controllable effect on the structural strength of the inner peripheral wall of the inner cylinder 2. In addition, the aperture of the water hole should not be too large or too small, because too large an aperture will affect the structural strength of the inner peripheral wall of the inner cylinder 2, and too small an aperture will be unfavorable for the washing water to enter the water containing cavity 21, and it is usually larger than the aperture of the filter hole 44.

[0057] See also Figures 9 to 11In some embodiments, the filter 4 includes a front cover 42, a rear cover 41 and a check plate 43. The front cover 42 and the rear cover 41 enclose a filter chamber 40, the rear cover 41 has the first chamber wall 411, and the front cover 42 has the second chamber wall 421. The front cover 42 may include a front cover 42 body and a front cover 42 side plate arranged at the edge of the front cover 42 body, the front cover 42 body and the front cover 42 side plate are combined to form a front cover 42 with one end open, the rear cover 41 body may include a rear cover 41 body and a rear cover 41 side plate arranged at the edge of the rear cover 41, the rear cover 41 body and the rear cover 41 side plate are combined to form a rear cover 41 with one end open, the open end of the front cover 42 is opposite to the open end of the rear cover 41, one of the two is engaged with the other, the front cover 42 side plate and the rear cover 41 side plate are connected to enclose a filter chamber 40, so that the filter 4 can be easily disassembled, and the wire scraps deposited therein can be conveniently removed after using it for a period of time.

[0058] In some embodiments, one of the side panels of the front cover 42 and the side panels of the rear cover 41 may be provided with a buckle, and the other may be provided with a buckle position at a corresponding position, and the buckle is buckled in the buckle position to connect and fix the front cover 42 and the rear cover 41.

[0059] In some embodiments, the bottom ends of the front cover 42 and the rear cover 41 are hinged by a rotating shaft, so that the front cover 42 can rotate relative to the rear cover 41. The rotation of the two separates the top ends of the front cover 42 and the rear cover 41, and the filter chamber 40 is opened. The user can reach into the filter chamber 40 between the top ends of the front cover 42 and the rear cover 41 to take out the wire scraps. It is understandable that the top ends of the front cover 42 and the rear cover 41 can also be hinged by a rotating shaft, and when the two rotate, the bottom ends of the front cover 42 and the rear cover 41 are separated. The rotating shaft can be set on the side plate of the rear cover 41 in the rear cover 41, and the rotating hole can be set on the side plate of the front cover 42 in the front cover 42. The rotating shaft is rotatably set in the rotating hole to realize the hinge connection between the two. Similarly, it can be known that the rotating shaft can also be set on the side plate of the front cover 42, and the rotating hole is opened on the side plate of the rear cover 41.

[0060] In some embodiments, the check plate 43 is movably arranged in the filter chamber 40 and close to the water inlet. The check plate 43 can be switched between a first position and a second position. When the check plate 43 is in the first position, there is a gap between the check plate 43 and the water inlet, and the water inlet is in an open state. When the washing machine is working, the impeller 5 drives the washing water to churn up and down. The washing water has upward kinetic energy. The washing water enters the filter chamber 40 from the gap, and the lint also enters the filter chamber 40.

[0061] When the check plate 43 is in the second position, the check plate 43 closes the water inlet to prevent the washing water from flowing out of the water inlet. At this time, the lint is retained in the filter chamber 40 and gradually settles down. As the pulsator 5 rotates continuously, the washing water churns up and down continuously, and the check plate 43 opens or closes the water inlet continuously, so that more and more lint is retained in the filter chamber 40, thereby improving the lint removal capability of the washing machine.

[0062] Specifically, a card slot 45 is provided at the bottom of the front cover 42 on the side facing the rear cover 41, and the notch of the card slot 45 faces the rear cover 41. The anti-return plate 43 is obliquely arranged in the filter chamber 40, and the lower end of the anti-return plate 43 has a card connection portion 431, and the card connection portion 431 is clamped in the card slot 45 to relatively fix the anti-return plate 43. The higher end of the anti-return plate 43 can be overlapped on the rear cover 41 to close the water inlet.

[0063] In some embodiments, the anti-return plate 43 is a flexible member that can undergo elastic deformation. When the washing water rushes upward into the water inlet under the rotation of the impeller 5, it has a certain kinetic energy, which can cause the higher end of the anti-return plate 43 to undergo elastic deformation and move a short distance away from the rear cover 41, so that the anti-return plate 43 is located in the first position. There is a gap between the anti-return plate 43 and the water inlet, and the washing water enters the filter cavity from the gap. After entering the filter cavity, the washing water falls downward under the action of gravity, and the higher end of the anti-return plate 43 moves toward the direction close to the rear cover 41 until it overlaps with it, thereby closing the water inlet. At this time, the anti-return plate 43 is in the second position. As the washing water continues to tumble up and down, the anti-return plate 43 continuously switches between the first position and the second position. Among them, the cross-section of the card slot 45 can be rectangular, and the clamping part 431 can be a rectangular column structure that cooperates with it. It is clamped in it to prevent it from rotating. However, since the anti-return plate 43 is a flexible part, its higher end can be elastically deformed and move. The higher end of the anti-return plate 43 refers to the end that is higher in the up and down direction, and the lower end refers to the end that is lower than the higher end in the up and down direction.

[0064] The anti-return sheet 43 can be made of a flexible material such as rubber, polyimide, polyester, etc. into a sheet structure so as to enable elastic deformation.

[0065] In some other embodiments, the lower end of the check piece 43 can also be rotatably disposed on the front cover 42, and the higher end thereof is overlapped on the rear cover 41. When the washing water enters the water inlet from bottom to top, the check piece 43 is forced to rotate, thereby opening the water inlet, allowing the washing water to enter the filter chamber. When the washing water in the filter chamber falls back due to gravity, the check piece 43 is forced to rotate to connect with the rear cover 41, thereby closing the water inlet. It is understandable that in order to achieve a good effect of the check piece 43 closing the water inlet, when the check piece 43 is in the second position, it should cover the water inlet, which can reduce the probability of the wire scraps leaking out.

[0066] See also Fig.12 In some embodiments, a support member 46 is further provided in the filter chamber 40, and the support member 46 is located at the bottom side of the check plate 43. When the check plate 43 is in the second position, the check plate 43 is supported on the support member 46, thereby providing a better support for the check plate 43 and preventing the check plate 43 from being deformed due to the impact of the washing water when it falls back, thereby allowing the wire scraps to flow back to the bottom of the inner drum 2 through the gap formed by the deformation.

[0067] Specifically, the support member 46 can be a support rib plate, one end of which is fixedly connected to the rear cover 41 and extends toward the front cover 42 to form a support surface 461, which is flush with the bottom surface of the anti-return plate 43 when it is in the second position, thereby expanding the contact area between the support member 46 and the anti-return plate 43 through surface contact to avoid stress concentration. In some embodiments, one end of the support member 46 can also be fixedly connected to the front cover 42. It is understandable that the support rib plate is a right-angled triangular rib plate, and the inclined surface of the support rib plate forms the support surface 461, so that the support rib plate has a higher strength and can support the anti-return plate 43.

[0068] Furthermore, at least two support members 46 are provided, and at least two support members 46 are arranged at intervals along the width direction of the rear cover 41, so as to replace and support the middle area of ​​the anti-return plate 43, and prevent the anti-return plate 43 from collapsing and deforming in the middle under the impact of the falling washing water. A channel for washing water to enter the filter chamber 40 is formed between adjacent support members 46, which does not affect the normal washing water entering the filter chamber 40. In this embodiment, four support members 46 are provided, which are evenly spaced in the width direction of the rear cover 41, and the two support members 46 at both ends can be integrally formed on the side plate of the front cover 42 or the side plate of the rear cover 41 to support the two side edges of the anti-return plate 43.

[0069] In some embodiments, a plurality of grid holes are provided on the first cavity wall 411 and the second cavity wall 421 at intervals. The grid holes can connect the filter chamber 40 with the water containing cavity 21 and the inner cylinder 2, while maintaining a certain structural strength of the first cavity wall 411 and the second cavity wall 421. A filter screen is provided in the grid holes, and the filter screen has a plurality of mesh holes, which constitute the filter holes 44. By providing the filter screen, the aperture of the filter hole 44 can be made to be able to filter the wire scraps, which is convenient for manufacturing and simple in process. Among them, the mesh number of the filter screen should be between 30 and 50 meshes, and the number of mesh lines of the filter screen should be less than 180 lines, so as to be able to adapt to the size of the wire scraps and filter the wire scraps.
