Description

Technical Field

[0001] This invention relates to the field of washing machine accessories technology, specifically a cleaning component for a pulsator washing machine. Background Technology

[0002] As an indispensable home appliance in modern families, washing machines have greatly liberated manpower and improved the efficiency and convenience of cleaning clothes. Among them, top-loading washing machines have core advantages such as simple structure, strong washing power, convenient operation, low maintenance cost, and affordable price. The core working principle of top-loading washing machines is that the rotation of the bottom cleaning component, namely the pulsator, drives the water flow in the drum to form a rotating vortex. The impact force of the water flow, the friction between the clothes and the water flow, and the mutual friction between the clothes are used to remove and clean stains. However, in actual use, the existing cleaning components operate in a single mode, and the water flow only circulates in one direction, which easily causes clothes to become tangled and knotted, which not only affects the cleaning effect but also increases the wear and tear on the clothes.

[0003] To address the aforementioned deficiencies, existing technology (Chinese Patent No. CN218115884U, published on 2022-12-23) provides a clothes cleaning assembly for a washing machine drum. The assembly includes a washing machine with a front door and an inner drum. A mounting base is formed between the inner drum and the front door. A clothes cleaning assembly is housed within the mounting base. The clothes cleaning assembly includes a cleaning base plate. The cleaning base plate has multiple protrusions on its side facing the inner drum and grooves. The grooves and protrusions form a pulsator structure that increases friction on the clothes. An elastic buckle is provided circumferentially on the mounting base. The cleaning base plate has a groove that engages with the elastic buckle. The cleaning base plate is connected to the mounting base via the elastic buckle. Through this method, the clothes cleaning assembly for the washing machine drum of this utility model adds a clothes cleaning component between the front door and the inner drum. The friction between the clothes cleaning component and the clothes improves the cleaning effect. The structure is simple, safe, reliable, and effective. A prior art (Chinese patent publication number CN221701868U, publication date 2024-09-13) describes a washing machine agitator impeller, comprising a circular plate with several circular holes at its upper end, arranged in groups of four. Several cleaning components are fixedly connected to the upper end of the circular plate, arranged in a ring. Several sets of circular holes are also arranged in a ring. Several primary cleaning plates are fixedly connected to the upper end of the circular plate, arranged in a ring. The primary cleaning plates, cleaning components, and sets of circular holes are alternately distributed. A circular block is fixedly connected to the center of the upper end of the circular plate, with mounting holes on its lower inner wall. A blocking device is movably connected to the upper end of the circular block. This invention, through the arrangement of primary cleaning plates and cleaning components, improves the washing efficiency of clothes.

[0004] In the above-mentioned solutions, the cleaning strips are mostly rigid structures in a fixed state. During the cleaning process, they rely solely on the mechanical friction between the clothes and the drum, resulting in limited cleaning efficiency. To achieve a good cleaning effect, they often require more water and electricity, and their water-saving and energy-saving performance is poor. Summary of the Invention

[0005] The purpose of this invention is to provide a cleaning component for a pulsator washing machine, in order to solve the problems mentioned in the background art regarding the existing cleaning components of pulsator washing machines. In use, the cleaning protrusions are mostly rigid structures in a fixed state, and the cleaning process relies solely on the mechanical friction between the clothes and the drum, resulting in limited cleaning efficiency. In order to achieve a good cleaning effect, more water and electricity are often required, resulting in poor water and energy saving performance.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a cleaning component for a pulsator washing machine, including a pulsator disc, a docking shaft integrally installed at the bottom of the pulsator disc and connected to the output end of the washing machine motor, a cleaning drum sleeved at the top edge of the pulsator disc, and main flexible cleaning protrusions installed at equal angles on the top surface of the pulsator disc; The surface of the main flexible cleaning ridge is provided with equidistant backflow grooves, and the periphery of the top surface of the impeller is provided with secondary flexible cleaning ridges at equal angles. The interiors of the main and secondary flexible cleaning ridges are both hollow structures. The interiors of the main and secondary flexible cleaning ridges are respectively provided with a first sliding component and a second sliding component. The interior of the impeller is provided with a first telescopic adjustment component and a second telescopic adjustment component to adjust the sliding component. At the same time, an energy-saving power recovery component is provided inside the impeller and outside the docking shaft.

[0007] Furthermore, the main flexible cleaning protrusion is configured as a spiral structure, and the flow direction of the counterflow channel is staggered with the flow direction of the main flexible cleaning protrusion.

[0008] Furthermore, the first sliding component includes a vertical cylinder and a column installed in the hollow structure of the main flexible cleaning ridge. The vertical cylinder is fixed to the inner bottom of the hollow structure of the main flexible cleaning ridge, and the column is slidably connected to the top of the vertical cylinder. The top of the column is fixedly connected to the top of the hollow structure of the main flexible cleaning ridge.

[0009] Furthermore, the second sliding assembly includes a carriage that is slidably connected to the bottom of the secondary flexible cleaning protrusion. The carriage is configured with a "T" shape, and the bottom of the carriage is threadedly connected to a screw. The screw is rotatably connected to the top of the impeller at an equal angle. The secondary flexible cleaning protrusion forms a telescopic sliding structure through the screw and the carriage.

[0010] Furthermore, the first telescopic adjustment assembly includes electric push rods installed at equal intervals inside the impeller disk. A fixed cylinder is fixed to the end of the electric push rod, and a toothed plate is fixed to the end of the fixed cylinder that is slidably connected to the slide plate. A gear is meshed with the outer side of the toothed plate, and a screw is integrally installed in the middle of the gear.

[0011] Furthermore, the sliding plate reciprocates within the fixed drum as the washing machine rotates, and the slide frame forms a vertical telescopic structure through the sliding plate, toothed plate, gear, and screw.

[0012] Furthermore, the second telescopic adjustment assembly includes a sleeve fixed to the end of the toothed plate. The sleeve is slidably fitted onto the outside of the sleeve rod, which is fixed inside the impeller. The inside of the sleeve is connected to the vertical cylinder through a connecting pipe. The main flexible cleaning convex strip forms an elastic telescopic structure through the vertical cylinder and the column.

[0013] Furthermore, the power recovery assembly includes a permanent magnet fixed to the outside of the docking shaft. The outside of the permanent magnet is sleeved inside the coil. The coil is fixedly connected to the base of the washing machine. After the permanent magnet rotates, it cuts the magnetic field lines with the coil. The generated electricity is stored in a battery. The battery is configured as a toroidal battery pack and supplies power to the electric push rod.

[0014] Furthermore, the impeller is equipped with a rectifier and voltage regulator module. When the docking shaft drives the permanent magnet to rotate back and forth for cleaning, the generated AC power is converted into DC power by the rectifier and voltage regulator module and stored in the battery.

[0015] Furthermore, the direct current generated when the docking shaft drives the permanent magnet to rotate at high speed in one direction for dehydration is directly stored in the battery.

[0016] Compared with the prior art, the beneficial effects of the present invention are: The washing components of this pulsator washing machine increase water flow disturbance and washing contact through the flexible extension and retraction adjustment of the main and auxiliary flexible washing protrusions during use, thereby improving the washing efficiency and quality of clothes. The anti-flow channel changes the direction of water flow to prevent clothes from tangling. At the same time, the power recovery component regulates the power supply to the components, achieving a synergistic effect of improved cleaning efficiency, reduced wear and tear on clothes, and energy and water conservation.

[0017] 1. Furthermore, both the main flexible cleaning strip and the secondary flexible cleaning strip are hollow flexible structures. With the help of a dedicated sliding component and telescopic adjustment component, they can achieve elastic extension and contraction in the vertical direction. This avoids the poor cleaning effect caused by the fixed height of the strip and allows the clothes to be fully contacted and agitated by the strip. This solves the problem of poor cleaning uniformity of traditional rigid fixed strips. By combining the flexible structure with mechanical telescopic adjustment, the cleaning component has better cleaning adjustment capabilities.

[0018] 2. Furthermore, the surface of the spiral-shaped main flexible cleaning ridges is provided with staggered flow counterflow grooves. When the impeller rotates, the main flexible cleaning ridges drive the water flow to form a basic rotating vortex, while the counterflow grooves simultaneously guide the water flow to form a reverse flow. This, combined with the water flow disturbance formed by the secondary flexible cleaning ridges around the impeller, breaks the single water flow circulation mode of traditional cleaning components, fundamentally preventing clothes from tangling and knotting. At the same time, it increases the frequency of contact and friction between the water flow and clothes, and between clothes themselves, and also makes up for the cleaning blind spots in the edge area of ​​the washing drum. Through the combined design of the ridge structure and the counterflow grooves, the cleaning efficiency is improved while reducing the wear and tear on clothes.

[0019] 3. Furthermore, the permanent magnet outside the docking shaft rotates with the impeller and cuts magnetic field lines with the fixed coil. The AC power generated during the washing stage is converted into DC power by the rectifier and voltage regulator module. The DC power generated during the spin-drying stage can be directly stored in the toroidal battery. The battery powers the electric push rod that drives the extension and retraction of the convex strip. The whole process converts the mechanical energy of washing and spin-drying of the washing machine into electrical energy for recycling and reuse. There is no need to consume additional external power for the extension and adjustment components. This solves the problem that traditional washing components need to consume more water and electricity to improve the cleaning effect and have poor energy efficiency. It realizes the recycling of energy and reduces the overall energy consumption.

[0020] 4. Furthermore, with the impeller as the core carrier, the extension and retraction adjustment of the main and auxiliary flexible cleaning strips, the formation of multiple water flows, and the power recovery and energy supply components are organically integrated. This breaks the traditional design mode in which each functional module of the cleaning component is independent. The overall structure is compact and the layout is reasonable. While improving the comprehensive performance of the cleaning component, it also meets the internal installation and adaptation requirements of the impeller washing machine. There is no need to make major modifications to the main body of the washing machine, making it more practical. Attached Figure Description

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Example 1: Please refer to Figure 1 - Figure 9The present invention provides the following technical solution: a cleaning component for a pulsator washing machine, including a pulsator disk 1, a docking shaft 2 integrally installed at the bottom of the pulsator disk 1 and connected to the output end of the washing machine motor, a cleaning drum 3 sleeved at the top edge of the pulsator disk 1, main flexible cleaning protrusions 4 installed at equal angles on the top surface of the pulsator disk 1, anti-flow grooves 5 evenly spaced on the surface of the main flexible cleaning protrusions 4, secondary flexible cleaning protrusions 6 installed at equal angles around the top surface of the pulsator disk 1, both the main flexible cleaning protrusions 4 and the secondary flexible cleaning protrusions 6 having a hollow internal structure, a first sliding component and a second sliding component respectively provided inside the main flexible cleaning protrusions 4 and the secondary flexible cleaning protrusions 6, a first telescopic adjustment component and a second telescopic adjustment component for adjusting the sliding components provided inside the pulsator disk 1, and an energy-saving power recovery component provided inside the pulsator disk 1 and outside the docking shaft 2.

[0025] Its core lies in the fact that the impeller 1 is driven by a motor to complete the basic rotational cleaning, and the water flow direction is adjusted in multiple ways by relying on the anti-flow groove 5 to avoid clothes from tangling. With the linkage of the first and second telescopic adjustment components and the sliding component, the height of the main flexible cleaning ridge 4 and the secondary flexible cleaning ridge 6 can be flexibly adjusted to improve the uniformity of cleaning. At the same time, the power recovery component converts the mechanical energy of the washing machine into electrical energy to power the component adjustment, achieving energy and water conservation. The various components work together and work in linkage, which solves the problems of the traditional cleaning component's single operation mode, inability to adjust the ridges, and high energy consumption. While improving cleaning efficiency, it reduces the wear and tear on clothes and achieves the dual effect of cleaning and energy saving.

[0026] Specifically, the main flexible cleaning protrusion 4 is configured as a spiral structure, and the flow direction of the counterflow groove 5 is staggered with the flow direction of the main flexible cleaning protrusion 4.

[0027] refer to Figure 2 - Figure 4 and Figure 6 As shown, the docking shaft 2 at the bottom of the impeller 1 is connected to the output end of the washing machine motor. The motor drives the docking shaft 2 to rotate the impeller 1. The spiral-shaped main flexible cleaning protrusions 4, which are set at equal angles on the top surface of the impeller 1, rotate with the impeller 1, causing the water flow in the washing drum 3 to form a basic rotating vortex, realizing the impact and friction cleaning of the clothes by the water flow. The counterflow grooves 5, which are opened at equal intervals on the surface of the main flexible cleaning protrusions 4, are arranged in an alternating direction with the flow direction of the protrusions. During the rotation, part of the water flow forms a reverse flow through the counterflow grooves 5, breaking the single-direction water flow circulation and preventing the clothes from getting tangled due to the unidirectional rotation of the water flow. At the same time, it increases the frequency of contact and friction between the water flow and the clothes, and between the clothes, improving the uniformity of cleaning. The secondary flexible cleaning protrusions 6 around the top surface of the impeller 1 cooperate with the main flexible cleaning protrusions 4 to further enhance the cleaning of the clothes in the inner edge area of ​​the washing drum 3, making up for the cleaning blind spots of a single protrusion.

[0028] Specifically, the second sliding assembly includes a slide 7 that is slidably connected to the bottom of the secondary flexible cleaning protrusion 6. The slide 7 is configured as a "T" shape. The bottom of the slide 7 is threadedly connected to the screw 13. The screw 13 is rotatably connected to the top of the impeller 1 at equal angles. The secondary flexible cleaning protrusion 6 forms a telescopic sliding structure through the screw 13 and the slide 7. The first telescopic adjustment assembly includes an electric push rod 8 that is installed at equal intervals inside the impeller 1. The end of the electric push rod 8 is fixed with a fixed cylinder 9. The end of the slide plate 10 that is slidably connected to the fixed cylinder 9 is fixed with a toothed plate 11. The outer side of the toothed plate 11 is meshed with a gear 12. The middle of the gear 12 is integrally installed with a screw 13. The slide plate 10 slides back and forth in the fixed cylinder 9 as the washing machine rotates. The slide 7 forms a vertical telescopic structure through the slide plate 10, the toothed plate 11, the gear 12 and the screw 13.

[0029] refer to Figure 6 - Figure 9 As shown, when the impeller 1 reciprocates during the washing process, the slide plate 10 slides synchronously within the fixed drum 9 due to inertia, causing the toothed plate 11 to move. The toothed plate 11 meshes with the gear 12, driving the screw 13 in the middle of the gear 12 to rotate. When the screw 13 rotates, the slide 7, which is threaded to it, slides vertically, thereby causing the secondary flexible washing protrusion 6 to extend and retract, thus adjusting the height of the protrusion. When the amount of clothes inside the washing machine is large, the speed of the impeller 1 will decrease during washing. The washing machine is equipped with a sensor to detect the speed of the impeller 1. When the speed is lower than the threshold of the washing state, the control module is triggered to adjust the speed, and the electric push rod 8 will start, thereby pushing the fixed drum 9 to move and maintaining the movement of the slide plate 10. This keeps the slide 7 sliding in the secondary flexible washing protrusion 6, thus maintaining the disturbance and contact effect on the water flow and clothes. This process can be set by the program.

[0030] Specifically, the first sliding assembly includes a vertical cylinder 14 and a column 15 installed in the hollow structure of the main flexible cleaning protrusion 4. The vertical cylinder 14 is fixed to the bottom inner side of the hollow structure of the main flexible cleaning protrusion 4, and the column 15 is slidably connected to the top of the vertical cylinder 14. The top of the column 15 is fixedly connected to the top of the hollow structure of the main flexible cleaning protrusion 4. The second telescopic adjustment assembly includes a sleeve 16 fixed to the end of the toothed plate 11. The sleeve 16 is slidably fitted on the outside of the sleeve rod 17. The sleeve rod 17 is fixed inside the impeller 1. The inside of the sleeve 16 is connected to the vertical cylinder 14 through a connecting pipe. The main flexible cleaning protrusion 4 forms an elastic telescopic structure through the vertical cylinder 14 and the column 15.

[0031] refer to Figure 5 and Figure 8 - Figure 9As shown, when the toothed plate 11 moves, it will drive the sleeve 16 to slide along the sleeve rod 17. The medium inside the sleeve 16 is output after being squeezed and enters the interior of the vertical cylinder 14 through the connecting pipe. The vertical cylinder 14 pushes the column 15 to slide vertically, which in turn drives the main flexible cleaning convex strip 4 to complete elastic extension and contraction. In conjunction with the secondary flexible cleaning convex strip 6, the overall height of the convex strip is adjusted in a coordinated manner, thereby improving the cleaning efficiency and quality of clothes.

[0032] Example 2: Based on Embodiment 1, a power recovery mechanism is also disclosed; please refer to [reference needed]. Figure 1 and Figure 10 - Figure 11 As shown, its specific structure is as follows: The power recovery component includes a permanent magnet 18 fixed to the outside of the docking shaft 2. The outside of the permanent magnet 18 is sleeved inside the coil 19. The coil 19 is fixedly connected to the base of the washing machine. After the permanent magnet 18 rotates, it cuts the magnetic field lines with the coil 19. The generated electricity is stored in the battery 21. The battery 21 is set as a ring battery pack. The battery 21 supplies power to the electric push rod 8. The impeller 1 is equipped with a rectifier and voltage regulator module 20. When the docking shaft 2 drives the permanent magnet 18 to rotate back and forth for washing, the generated AC power is converted into DC power by the rectifier and voltage regulator module 20 and stored in the battery 21. When the docking shaft 2 drives the permanent magnet 18 to rotate unidirectionally at high speed for dehydration, the generated DC power is directly stored in the battery 21.

[0033] refer to Figure 1 and Figure 10 - Figure 11 As shown, during the washing stage, the docking shaft 2 drives the permanent magnet 18 to rotate back and forth. The permanent magnet 18 moves relative to the coil 19 and cuts the magnetic field lines, generating alternating current. This alternating current is converted into direct current by the rectifier and voltage regulator module 20 inside the impeller 1 and stored in the battery 21. During the dehydration stage, the docking shaft 2 drives the permanent magnet 18 to rotate at high speed in one direction. The direct current generated by cutting the magnetic field lines can be directly stored in the battery 21. The electrical energy stored in the battery 21 provides power for the electric push rod 8. There is no need to consume the external power of the washing machine, realizing the recovery and reuse of power and reducing the overall energy consumption.
