Description

Technical Field

[0001] This invention relates to the field of washing machine auxiliary washing tools, and in particular to a washing machine washing ball that accelerates the dissolution of fragrance beads. Background Technology

[0002] As people's living standards continue to improve, their requirements for clothing cleaning and care are no longer limited to basic stain removal. While pursuing cleanliness, consumers are increasingly focusing on the longevity of the fragrance and the wearing experience after washing. Fragrance beads, as a new type of clothing care product, are highly favored by the market for their ability to impart a lasting fragrance to clothes. However, traditional fragrance beads have low compatibility with washing machines. Generally, they are placed directly in the detergent dispenser or poured directly into the drum. During the washing process, the fragrance beads are easily thrown to the side of the drum or trapped inside the clothes, failing to fully contact the water flow. This can lead to incomplete dissolution and uneven distribution, resulting in poor fragrance retention on some clothes and even residual particles that damage clothing fibers.

[0003] In the field of laundry aids, washing machine scouring pads that accelerate the dissolution of fragrance beads have been widely used as a tool to improve washing performance. Existing washing machine scouring pads that accelerate the dissolution of fragrance beads mainly enhance cleaning power through physical friction, while also achieving a slow-release function by incorporating detergent inside. For example, patent CN212052007U discloses a washing fragrance scouring pad, including an upper hemisphere and a lower hemisphere symmetrically arranged thereto. The bottom of the upper hemisphere has a sub-torsion ring, and the outer side of the sub-torsion ring has a locking block. The top of the lower hemisphere has a female torsion ring, and the inner side of the female torsion ring has a clearance groove. One side of the clearance groove has a fixing member, which includes a limiting block and a locking groove. The top of the clearance groove has an insertion groove, and the bottom of the limiting block has a protrusion. Both sides of the bottom of the protrusion have first rounded corners, and both sides of the top of the locking block have second rounded corners. Both the upper and lower hemispheres have through holes, and the fragrance scouring pad can be easily installed and removed through the movable engagement of the sub-torsion ring and the female torsion ring.

[0004] However, in the quick wash mode of the washing machine, due to the short wash time and the fact that the fragrance beads are solid granules, the dissolution time is long. The water flow cannot fully penetrate the inside of the fragrance beads, which may cause the undissolved fragrance beads to overflow with the water flow and directly adhere to the clothes, resulting in an overly strong fragrance in some areas or even staining residue, thus failing to fully exert the effectiveness of the fragrance beads. Summary of the Invention

[0005] In order to address the technical deficiencies mentioned in the background art, the purpose of this invention is to provide a washing machine detergent ball that accelerates the dissolution of fragrance beads, thereby solving the problem of insufficient dissolution and easy residue of fragrance beads in the quick wash mode in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A washing machine detergent ball for accelerating the dissolution of fragrance beads includes a detachably connected upper hemisphere and a lower hemisphere. The upper and lower hemispheres have a plurality of water-passing holes evenly distributed on them. When the upper and lower hemispheres are engaged, they form a dissolution cavity for accommodating solid fragrance beads. A fixed shaft is vertically positioned at the center of the inner bottom of the lower hemisphere, and a water-driven fan blade is rotatably mounted on the fixed shaft. The water-driven fan blade includes a hub and a plurality of blades mounted on the hub. The blades are radially distributed around the outer periphery of the hub and are located within the dissolution cavity. A gap is left between the outer edge of the blades and the inner wall of the lower hemisphere.

[0008] Preferably, the blade is a curved blade or a straight blade, and the water-facing surface of the blade forms an angle of 30°-60° with the radial line of the fixed axis.

[0009] Preferably, the top of the fixed shaft is provided with a limiting cap, the limiting cap and the fixed shaft are integrally formed, and the diameter of the limiting cap is larger than the diameter of the center hole of the hub.

[0010] Preferably, the water passage includes an inlet and an outlet located on the surfaces of the upper and lower hemispheres, the opening area of ​​the inlet being larger than that of the outlet, and the mesh size of the outlet being smaller than that of the fragrance beads.

[0011] Preferably, the top of the upper hemispherical shell is provided with an openable feeding port, and the feeding port is provided with an elastic sealing cover, which is interference-fitted with the feeding port.

[0012] Preferably, the upper hemispherical shell has a guide cone at its inner top, the guide cone is coaxially arranged with the feeding port, and the cone surface of the guide cone faces the hydraulically driven fan blade; the bottom of the guide cone has a discharge port, the discharge port is crescent-shaped and communicates with the dissolving chamber.

[0013] Preferably, the guide cone has a double-layer structure, with an outer fixed guide cone and an inner movable guide cone; the movable guide cone is rotatably connected inside the fixed guide cone, and the top of the movable guide cone is engaged with the elastic sealing cover.

[0014] Preferably, a filter screen is detachably connected to the bottom of the upper hemispherical shell, and the filter screen has a clearance hole at the position corresponding to the flow guide cone, and the mesh size of the filter screen is smaller than the particle size of the fragrance beads.

[0015] Preferably, the inner bottom of the lower hemispherical shell is provided with a plurality of radially distributed guide ribs. The guide ribs extend from the root of the fixed shaft to the inner wall of the lower hemispherical shell, and a guide groove is formed between two adjacent guide ribs. The bottom of the guide groove gradually decreases from the outside to the inside and communicates with the root of the fixed shaft.

[0016] Preferably, the outer surfaces of the upper and lower hemispheres are further provided with a plurality of anti-tangling spikes to prevent clothing from tangling and to serve as friction for cleaning; the anti-tangling spikes are hemispherical or conical protrusions and are distributed alternately on the upper and lower hemispheres.

[0017] In summary, the beneficial effects of the present invention are as follows:

[0018] 1. During the washing process, water flows into the dissolving chamber through the water passage on the casing. The incoming water impacts the blades of the hydraulically driven fan, generating torque that drives the fan blades to rotate at high speed around a fixed axis. The rotation of the fan blades forcibly agitates the water and fragrance beads in the dissolving chamber, creating forced convection. This forced convection continuously washes the surface of the fragrance beads with fresh water, significantly accelerating the dissolving process. At the same time, it prevents the fragrance beads from accumulating at the bottom of the spheres, preventing undissolved particles from directly overflowing and contacting clothes, thus eliminating problems such as staining or uneven fragrance retention. The dissolved fragrance liquid is discharged from the spheres through the water passage with the water flow, and is evenly distributed inside the washing machine drum.

[0019] 2. This invention utilizes the built-in water-driven fan blades, which are driven by the water flow of the washing machine itself, to rotate the fan blades without the need for additional energy. This achieves forced agitation of the solid fragrance beads, greatly shortening the dissolution time. It is especially compatible with the quick wash mode of washing machines, ensuring that the fragrance beads are completely dissolved within a short cycle of 15-30 minutes, thus improving washing efficiency and user experience.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention are within the scope of protection of the present invention.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limiting this invention.

[0031] In the description of this invention, the use of terms such as "a number" means one or more, with "more than" meaning two or more. Terms like "greater than," "less than," and "exceeding" are understood to exclude the stated number, while terms like "above," "below," and "within" are understood to include the stated number. The use of terms like "first," "second," and "third" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, the number of indicated technical features, or the sequential relationship between indicated technical features.

[0032] The following is in conjunction with the appendix Figure 1-7 The present invention will be further described in detail with respect to an embodiment of a washing machine detergent ball that accelerates the dissolution of fragrance beads.

[0033] A washing machine detergent ball that accelerates the dissolution of fragrance beads, such as Figure 1 , 2As shown, the device includes a detachably connected upper hemispherical shell 1 and a lower hemispherical shell 2. Several water passage holes are evenly distributed on the upper hemispherical shell 1 and the lower hemispherical shell 2. When the upper hemispherical shell 1 and the lower hemispherical shell 2 are fastened together, a dissolving cavity 22 is formed to accommodate solid fragrance beads. A fixed shaft 3 is vertically provided at the center of the inner bottom of the lower hemispherical shell 2. A hydraulically driven fan blade 4 is rotatably sleeved on the fixed shaft 3. The hydraulically driven fan blade 4 includes a hub 41 and a plurality of blades 42 mounted on the hub 41. The blades 42 are radially distributed on the outer periphery of the hub 41 and are located inside the dissolving cavity 22. A gap is left between the outer edge of the blades 42 and the inner wall of the lower hemispherical shell 2.

[0034] Furthermore, both the upper hemisphere 1 and the lower hemisphere 2 are integrally injection molded from food-grade PP material or ABS engineering plastic, with a shell wall thickness of 2-4mm to ensure sufficient mechanical strength to resist the impact of tumbling within the washing machine drum. Simultaneously, lightweight design is considered, with the total weight of a single washing ball controlled within the range of 80-150g to avoid excessive impact on the washing machine's load balancing system. The upper hemisphere 1 and lower hemisphere 2 are connected by threads or snap-fit ​​connections, and a sealing ring is provided at the connection point. An oil-impregnated bearing or polyoxymethylene bushing is embedded in the center hole of the hub 41 to reduce the rotational friction coefficient between the hub 41 and the fixed shaft 3, ensuring smooth start-up of the water-driven fan blades 4 even at low water flow rates. The axial thickness of the oil-impregnated bearing is 1 / 3-1 / 2 of the height of the hub 41, ensuring both support stability and allowing appropriate clearance for axial movement of the hub 41.

[0035] In this embodiment, as Figure 2 As shown, blade 42 is a curved blade or a straight blade, and the water-facing surface of blade 42 forms an angle of 30°-60° with the radial line of fixed axis 3.

[0036] Furthermore, the number of blades 42 is 18-23, preferably 21, and each blade 42 is distributed at an equal angle on the outer periphery of the hub 41. When curved blades are used, the curvature of the blade 42 is aligned with the direction of rotation, forming a volute effect similar to that of a centrifugal pump impeller, enhancing the suction and discharge capacity of the fluid in the dissolving chamber 22. When straight blades are used, the thickness of the blade 42 gradually decreases from the root to the tip to reduce water flow resistance and lower the moment of inertia of the blade 42, thereby improving response sensitivity. The gap between the outer edge of the blade 42 and the inner wall of the lower hemispherical shell 2 is 3-8 mm. This gap allows a small amount of fragrance beads to form a grinding layer between the blade 42 and the shell, assisting in breaking up larger particles, while avoiding excessive gaps that could lead to fluid short-circuiting and reduced stirring efficiency.

[0037] In this embodiment, as Figure 2As shown, the water passage includes an inlet hole 11 and an outlet hole 21 located on the surfaces of the upper hemisphere shell 1 and the lower hemisphere shell 2. The opening area of ​​the inlet hole 11 is larger than the opening area of ​​the outlet hole 21, and the mesh diameter of the outlet hole 21 is smaller than the particle size of the fragrance beads.

[0038] Furthermore, the distribution density of water passage holes on the shell surface is 0.5-1.2 per square centimeter. Both the water inlet hole 11 and the water outlet hole 21 adopt a round hole or waist-shaped hole structure. The diameter of the water inlet hole 11 is 4-8mm, and the diameter of the water outlet hole 21 is 1.5-3mm. The water outlet hole 21 is provided with an inwardly protruding annular reinforcing rib to prevent the hole edge from cracking and deforming due to long-term water flow.

[0039] In this embodiment, as Figure 4 , 6 As shown, a limiting cap 31 is provided on the top of the fixed shaft 3. The limiting cap 31 and the fixed shaft 3 are integrally formed, and the diameter of the limiting cap 31 is larger than the diameter of the center hole of the hub 41.

[0040] Furthermore, an axial clearance of 0.5-1.5mm is maintained between the bottom of the limiting cap 31 and the top surface of the hub 41. This clearance allows the hub 41 to rotate freely on the fixed shaft 3 while preventing the fan blades from shifting and dislodging under the impact of axial water flow. At the same time, the upper surface of the limiting cap 31 is designed with a spherical or conical transition to reduce water flow stagnation and eddy current generation on its surface, guiding the water flow smoothly downward into the working area of ​​the blade 42.

[0041] In this embodiment, as Figure 4 , 5 As shown, the top of the upper hemispherical shell 1 is provided with an openable feeding port 12, and an elastic sealing cover 5 is provided at the feeding port 12. The elastic sealing cover 5 is interference-fitted with the feeding port 12.

[0042] Furthermore, the diameter of the feeding port 12 is 25-40mm to meet the feeding requirements of mainstream fragrance beads on the market. The elastic sealing cap 5 is made of thermoplastic elastomer TPE or silicone rubber, and its top is provided with a handle for easy finger gripping. The handle is bent at 90° with the body of the elastic sealing cap 5, and the bending point has a thickness reduction area to facilitate repeated bending without fatigue breakage. At the same time, there are 2-3 annular sealing lips on the side wall of the elastic sealing cap 5. The outer diameter of the sealing lip is 1-2mm larger than the inner diameter of the feeding port 12, so that the interference fit between the elastic sealing cap 5 and the feeding port 12 is 0.3-0.8mm. During installation, the sealing lip is deformed under pressure to form multiple seals; it can still maintain a sealed state under the centrifugal force generated by the high-speed rotation of the washing machine, preventing the fragrance bead particles or solution in the dissolving chamber 22 from leaking from the feeding port 12.

[0043] In this embodiment, as Figure 4 , 5As shown, the upper hemispherical shell 1 has a guide cone 6 at its inner top. The guide cone 6 is coaxially arranged with the feeding port 12, and the cone surface of the guide cone 6 faces the hydraulically driven fan blade 4. The bottom of the guide cone 6 has a discharge port 63, which is crescent-shaped and connected to the dissolving chamber 22.

[0044] Furthermore, the cone angle of the guide cone 6 is 90°-120°, and the cone height is 15-25mm. This cone design allows the fragrance beads fed from the feeding port 12 to slide and disperse evenly along the cone surface. The guide cone 6 has a double-layer structure, with a fixed guide cone 61 on the outer layer and a movable guide cone 62 on the inner layer. The fixed guide cone 61 is integrally injection molded with the upper hemispherical shell 1, and the movable guide cone 62 is made of the same wear-resistant plastic as the fixed guide cone 61. The movable guide cone 62 is rotatably connected to the fixed guide cone 61, and the rotating mating surface between the two is provided with a lubricating grease groove to reduce wear during long-term use. The top of the movable guide cone 62 is engaged with the elastic sealing cover 5. At the same time, an outward-flaring edge is provided on the outer edge of the top of the movable guide cone 62, and a corresponding groove is provided on the inner top surface of the elastic sealing cover 5. When the elastic sealing cover 5 is closed, the outward-flaring edge is embedded in the groove, so that opening the elastic sealing cover 5 can drive the movable guide cone 62 to rotate at a certain angle, thereby changing the opening size of the crescent-shaped discharge port 63 and realizing a rough adjustment of the amount of fragrance beads dispensed.

[0045] For example, before adding the fragrance beads, the elastic sealing cap 5 is opened by rotating it. As the cap opens, the movable guide cone 62 rotates to a preset angle, causing the discharge port 63 of the movable guide cone 62 to misalign with the discharge port 63 of the fixed guide cone 61. This creates a storage cavity 13 within the guide cone 6 for quantitatively dispensing the fragrance beads. When the elastic sealing cap 5 is closed, it rotates in the opposite direction, causing the movable guide cone 62 to continue rotating. This aligns the discharge port 63 of the movable guide cone 62 with the discharge port 63 of the fixed guide cone 61. At this point, the fragrance beads can fall directly into the dissolving cavity 22 of the lower hemisphere shell 2 through the discharge port 63, thus achieving a single-quantity dispensing function and preventing incomplete dissolution or overly strong fragrance due to excessive dispensing.

[0046] In this embodiment, as Figure 5 As shown, a filter screen 7 is detachably connected to the bottom of the upper hemispherical shell 1. The filter screen 7 has an avoidance hole 71 at the position corresponding to the flow guide cone 6, and the mesh size of the filter screen 7 is smaller than the particle size of the fragrance beads.

[0047] Furthermore, the filter screen 7 is made of stainless steel wire woven mesh or nylon injection molded mesh with a mesh size of 0.8-1.5mm. This effectively intercepts undissolved fragrance beads while allowing the dissolved fragrance solution to pass through smoothly. The filter screen 7 has elastic buckles on its edges, and corresponding grooves on the bottom inner wall of the upper hemispherical shell 1. The filter screen 7 can be quickly installed and removed through the cooperation of the elastic buckles and grooves, facilitating regular cleaning and maintenance by the user. The diameter of the clearance hole 71 is slightly larger than the outer diameter of the bottom of the guide cone 6, ensuring unobstructed communication between the discharge port 63 of the guide cone 6 and the dissolving chamber 22 after the filter screen 7 is installed. Simultaneously, the edge of the clearance hole 71 has an upward-curving edge to prevent fragrance beads from leaking from the gap between the filter screen 7 and the guide cone 6.

[0048] It should be noted that the filter 7 can be installed selectively depending on daily use. When it is necessary to collect debris from washing clothes, the filter 7 can be snapped into place at the bottom of the upper hemisphere housing 1, so that the internal cavity of the upper hemisphere forms an independent filtration chamber for collecting debris or clumps of hair. Impurities such as lint and hair carried by the water flow are trapped by the filter 7 after entering the upper hemisphere housing 1, preventing blockage of the water outlet 21 or entanglement of the water-driven fan blades 4, ensuring the continuous and stable operation of the fan blades. When the filtration function is not needed, the filter 7 can be removed, so that the upper hemisphere housing 1 and the lower hemisphere housing 2 together form a larger dissolving chamber 22, which can accommodate different amounts of fragrance beads.

[0049] In this embodiment, as Figure 6 As shown, the lower hemispherical shell 2 has several radially distributed guide ribs 8 at its inner bottom. The guide ribs 8 extend from the root of the fixed shaft 3 to the inner wall of the lower hemispherical shell 2, and a guide groove 81 is formed between two adjacent guide ribs 8. The bottom of the guide groove 81 gradually decreases from the outside to the inside and is connected to the root of the fixed shaft 3.

[0050] Furthermore, the number of guide ribs 8 is the same as or an integer multiple of the number of blades 42, preferably 6-12, and the height of the guide ribs 8 is 1 / 5-1 / 3 of the height of the inner cavity of the lower hemisphere shell 2. The cross-section of the guide ribs 8 is streamlined, with a rounded transition on the water-facing side to reduce water flow resistance, and a vertical surface on the water-repellent side to enhance the guiding effect on the fragrance beads. The bottom inclination angle of the guide channel 81 is 5°-15°. This inclination design allows the fragrance bead particles deposited on the edge of the lower hemisphere shell 2 to automatically converge towards the center under the action of water flow and gravity, entering the strong stirring area of ​​the hydraulically driven fan blade 4, avoiding the formation of dead zones at the edge.

[0051] To further enhance the anti-tangling function and stain removal ability of the detergent ball, in this embodiment, as follows: Figure 2 , 3As shown, multiple anti-tangling spikes 9 are also provided on the outer surfaces of the upper hemisphere shell 1 and the lower hemisphere shell 2 to prevent clothing from tangling and to play a role in friction and stain removal; wherein, the anti-tangling spikes 9 are hemispherical or conical protrusions, and the anti-tangling spikes 9 are staggered on the upper hemisphere shell 1 and the lower hemisphere shell 2.

[0052] Furthermore, the root diameter of the anti-tangling spikes 9 is 8-15mm, the height is 5-10mm, the center-to-center distance between adjacent anti-tangling spikes 9 is 20-40mm, and the anti-tangling spikes 9 on the upper hemisphere shell 1 and the lower hemisphere shell 2 are staggered after being fastened together, forming a three-dimensional friction surface. The top of the anti-tangling spikes 9 is a smooth spherical surface or a blunt rounded surface to avoid scratching the clothing fibers. Nano silver ions or photocatalytic components can be added to the material to give the washing ball a certain antibacterial and deodorizing function.

[0053] It should be noted that the anti-tangling spikes 9 are made of elastic plastic material, which allows the anti-tangling spikes 9 to produce moderate elastic deformation when squeezed by clothing, ensuring effective isolation and friction against clothing, while avoiding damage to delicate fabrics from rigid collisions.

[0054] like Figure 7 As shown, the fluid dynamics process of the washing ball in this embodiment during actual operation is as follows:

[0055] In practical use, the detergent ball of this invention is placed into the washing machine drum along with the clothes. At the beginning of the wash cycle, the water inlet 11 quickly draws in washing water. Because the opening area of ​​the water inlet 11 is larger than that of the water outlet 21, the dissolving chamber 22 becomes full, and the water flow drives the hydraulically driven fan blade 4 to start rotating. The curved surface design or tilt angle of the blade 42 gives the fan blade a self-starting characteristic, enabling effective stirring even during the low water level soaking stage. As the washing machine drum rotates, the detergent ball is lifted to a high position and then falls, generating a strong mechanical stirring effect. At this time, the rotation direction of the hydraulically driven fan blade 4 and the tumbling motion of the detergent ball itself form a compound stirring mode. The fragrance beads are subjected to multi-dimensional shearing and impact forces within the dissolving chamber 22, accelerating the dissolving process.

[0056] During the main wash cycle, as the water flow velocity increases, the rotation speed of the hydraulically driven fan blades 4 increases accordingly. Local turbulence is formed in the gap between the outer edge of the blades 42 and the inner wall of the lower hemispherical shell 2, which grinds and refines any fragrance beads that may be present. At the same time, the conical surface of the guide cone 6 guides the water flow to form a downward scouring flow, which superimposes with the radial flow generated by the fan blades to construct a three-dimensional flow field in the dissolving chamber 22. This eliminates the concentration gradient layer in traditional static dissolving containers, allowing the high-concentration fragrance solution to diffuse outward through the water outlet 21 in a timely manner and fully contact the clothes.

[0057] During the rinsing stage, the detergent pods continue to function. Due to the small aperture of the water outlet 21, the residual fragrance bead solution in the dissolving chamber 22 continues to seep out in a slow-release manner, prolonging the adhesion time of the fragrance on the clothes. The anti-tangling tufted balls 9 continuously isolate tangled clothes during this process, and the nano-silver ions or photocatalytic components on their surface are activated in the humid environment, helping to remove residual odor molecules from the clothes.

[0058] The detergent beads of this invention are suitable for various types of washing machines, including top-loading, front-loading, and agitator-type washing machines. During a quick wash cycle, the complete dissolution time of the fragrance beads is shortened by 40%-60% compared to direct application, the fragrance lasts longer by 20%-30%, and the rate of clothing tangling is reduced by more than 50%. Users can quantitatively apply the fragrance beads according to the amount of laundry and their fragrance preference through the combination of the elastic sealing cap 5 and the movable guide cone 62. The amount applied at one time can be controlled within the range of 5-15g, meeting the needs of different usage scenarios.

[0059] To further verify the technical effects of the present invention, the inventors conducted a comparative experiment: under the same washing conditions (drum washing machine, quick wash mode, water temperature 30℃, washing time 20 minutes), equal amounts of standard soiled cloth were treated using three methods: directly adding fragrance beads, using ordinary perforated detergent balls, and using the detergent balls of the present invention. The results showed that the fragrance bead residue rate in the directly added group was 35%, the residue rate in the ordinary detergent ball group was 18%, while the residue rate in the detergent ball group of the present invention was only 3%. Furthermore, the uniformity of fragrance distribution on the clothing (measured by the coefficient of variation CV) decreased from 42% in the directly added group to 12% in the present invention group, indicating that the present invention has achieved significant technical progress in both accelerating dissolution and uniform distribution.

[0060] In summary, this invention, through the coordinated design of the hydraulically driven fan blade 4 and the washing ball shell structure, fully utilizes the existing water flow energy of the washing machine to achieve efficient dissolution and controllable release of fragrance beads, solving the industry pain points in the quick wash mode. It has outstanding advantages such as compact structure, no need for external energy, strong adaptability, and convenient use, and has good market promotion prospects.

[0061] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
