Description

Technical Field

[0001] This invention belongs to the field of washing equipment technology, specifically, it relates to a pulsator assembly and a washing device. Background Technology

[0002] Washing equipment is a cleaning appliance that uses electrical energy to generate mechanical action to wash clothes. Washing equipment can be divided into top-loading washing machines and front-loading washing machines. Among them, the drum of a top-loading washing machine is set vertically to the ground.

[0003] During the washing process using a pulsator in a washing machine, the pulsator can rotate forward or backward thanks to a motor located at the bottom of the tub. This forward and reverse rotation of the pulsator drives the rotation of the clothes and water inside the tub. The moving water then causes the clothes to tumble, creating friction between the clothes and between the clothes and the tub walls, which, combined with the action of the detergent, removes stains.

[0004] However, in the above washing process, relying solely on the forward or reverse rotation of a single impeller is insufficient to clean the clothes, resulting in poor cleaning performance of the washing equipment.

[0005] In response to this problem, some people have proposed washing equipment with multiple impellers. For example, Chinese invention patent No. 202310843362.6 proposes a dual-impeller washing machine. However, both impellers are set horizontally, and their agitation range for stirring clothes and rotating water is basically the same, which results in the washing equipment not significantly improving the washing effect on clothes.

[0006] In view of this, the present invention is hereby proposed. Summary of the Invention

[0007] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a pulsator assembly and washing equipment for washing equipment, so as to realize that the small pulsator assembly can efficiently assist the large pulsator in rinsing and stirring clothes. At least one small pulsator assembly is inclinedly set on the mounting wall of the large pulsator in the middle. The power distribution component makes the small pulsator assembly rotate, so that the pulsator of the washing equipment generates stronger impact force and stirring force when it is running, thereby enhancing the washing effect of the washing equipment.

[0008] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0009] This invention provides a pulsator assembly for a washing device, comprising:

[0010] The large impeller has a central protrusion protruding from its upper surface, and the central protrusion has a mounting wall;

[0011] At least one small impeller assembly is rotatably tilted and mounted on the mounting wall;

[0012] A power distribution unit is connected to the small impeller assembly. When the large impeller rotates, the power distribution unit generates torque on the small impeller assembly, and the torque causes the small impeller assembly to rotate about its axis center.

[0013] The present invention uses at least one small impeller assembly to be inclinedly mounted on the central protruding mounting wall of the large impeller, and the small impeller assembly is made to rotate by a power distribution component. This enables the impeller of the washing equipment to generate stronger impact and stirring force, and the small impeller assembly can effectively assist the large impeller in rinsing and stirring clothes, thereby enhancing the washing effect of the washing equipment.

[0014] A further embodiment of the present invention is that the central protrusion extends from one end along the diameter direction of the large impeller;

[0015] The mounting wall is formed by tilting downwards on at least one side of the central protrusion in its extending direction.

[0016] Preferably, the central protrusion extends from one end along the diameter of the large impeller to the other end, and the one end and the other end are symmetrically arranged along the rotation center of the large impeller.

[0017] The above solution further enables the central protrusion of the large impeller to stir the clothes to the side where the small impeller component is located, so that the small impeller component can better cooperate with the large impeller and more thoroughly disperse and stir the clothes.

[0018] A further embodiment of the present invention is that the lower side of the centrally protruding mounting wall has a mounting chamber;

[0019] The power distribution component is disposed within the mounting cavity;

[0020] One end of the shaft of the small impeller assembly passes through the mounting wall and is in contact with the power distribution component. When the large impeller rotates, the part of the small impeller assembly that is in contact with the power distribution component is subjected to a reaction torque, which causes the small impeller assembly to rotate around its shaft center.

[0021] In the above scheme, the internal space of the central protrusion is fully utilized to set up a power distribution component, which realizes the power for the rotation of the large impeller. The small impeller assembly can be made to rotate by the power distribution component, thus realizing the simultaneous rotation of the large impeller and the small impeller assembly by a single power source.

[0022] A further aspect of the present invention is that one end of the rotating shaft of the small impeller assembly has a first gear structure;

[0023] The power distribution unit has a second gear structure arranged in a ring around the periphery of the impeller shaft of the large impeller;

[0024] The first gear structure meshes with the second gear structure. When the large impeller rotates, the small impeller assembly revolves around the second gear structure. The first gear structure is subjected to the reaction torque of the second gear structure, and the torque causes the small impeller assembly to rotate.

[0025] In the above scheme, the first gear structure and the second gear structure ensure that the small impeller assembly is subjected to a stable reaction torque, thereby realizing the stable rotation of the small impeller assembly.

[0026] A further embodiment of the present invention is that the power distribution component has a sleeve structure sleeved on the outside of the impeller shaft of the large impeller, and the second gear structure is formed at the upper end of the sleeve structure.

[0027] In the above scheme, the sleeve structure ensures that the power distribution component has good structural strength, so that the power distribution component can remain stable when the second gear structure generates a reaction torque on the first gear structure.

[0028] A further aspect of the present invention is that the teeth of the second gear structure are inclined downwards from its inner ring to its outer ring, and the teeth of the first gear structure are inclined to mesh with the second gear structure.

[0029] The tooth angle of the first gear structure is smaller than the tooth angle of the second gear structure.

[0030] In the above scheme, the second gear structure engages with the first gear structure at an incline, and the tooth profile angle of the first gear structure is smaller than that of the second gear structure, which further realizes that the overall axial direction of the small wave wheel assembly can be tilted at a certain angle with the axial direction of the power distribution component.

[0031] A further embodiment of the present invention is that the central protrusion has two mounting walls that are radially symmetrical along the large impeller;

[0032] The small impeller assembly is arranged symmetrically in at least two sets along the rotation center of the large impeller.

[0033] The above solution incorporates multiple small impeller components, which effectively assist the large impeller in rinsing and agitating the clothes, further enhancing the washing effect of the washing equipment.

[0034] The present invention also provides a washing device having a tub for holding clothes, wherein the impeller assembly is disposed at the bottom of the tub.

[0035] A further embodiment of the present invention is that the power distribution component of the impeller assembly is fixedly disposed on the bottom wall of the barrel.

[0036] In the above solution, the impeller assembly is installed in conjunction with the bottom wall of the barrel.

[0037] A further aspect of the present invention is that the large impeller has a through hole connecting the mounting chamber and the interior of the barrel;

[0038] The bottom wall of the barrel has a chip removal hole that connects the installation chamber to the outside of the barrel. Fluid inside the barrel flows through the through hole into the installation chamber and is then discharged to the outside of the barrel through the chip removal hole.

[0039] In the above scheme, the centrally protruding mounting chamber can be used to house the power distribution component, as well as to discharge wire debris and water, thus achieving multiple uses for one chamber.

[0040] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0041] 1. By tilting at least one small impeller assembly onto the raised mounting wall in the middle of the large impeller, and by using a power distribution component to make the small impeller assembly rotate, the impeller of the washing equipment can generate stronger impact and agitation force. The small impeller assembly can also effectively assist the large impeller in rinsing and agitating the clothes, thereby enhancing the washing effect of the washing equipment.

[0042] 2. The large impeller is powered to rotate, and the small impeller assembly can be rotated through the power distribution component, thus enabling the large impeller and small impeller assembly to rotate simultaneously through a single power source.

[0043] 3. The centrally protruding mounting chamber can be used to house power distribution components, as well as to discharge wire debris and water, achieving multiple uses in one chamber.

[0044] The specific embodiments of the present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0060] like Figures 1 to 8 As shown, the present invention provides a pulsator assembly and a washing device for a washing equipment, so as to achieve the purpose of the small pulsator assembly 3 efficiently assisting the large pulsator 2 in rinsing and agitating clothes. By having at least one small pulsator assembly 3 inclinedly arranged on the mounting wall 24 protruding in the middle of the large pulsator 2, the power distribution component 4 causes the small pulsator assembly 3 to rotate, so that the pulsator of the washing equipment generates stronger impact force and agitation force when it is running, thereby enhancing the washing effect of the washing equipment.

[0061] Example 1

[0062] like Figures 1 to 7 As shown, this embodiment provides a pulsator assembly for a washing device, including: a large pulsator 2 having a central protrusion protruding from its upper surface, the central protrusion having a mounting wall 24; at least one small pulsator assembly 3, rotatably and obliquely disposed on the mounting wall 24; and a power distribution member 4 connected to the small pulsator assembly 3. When the large pulsator 2 rotates, the power distribution member 4 generates torque on the small pulsator assembly 3, the torque causing the small pulsator assembly 3 to rotate around its center.

[0063] It should be noted that the washing equipment is a pulsator type washing equipment equipped with the pulsator assembly, and the washing equipment uses the rotation of the large pulsator 2 and the small pulsator assembly 3 to rinsing and agitate the clothes.

[0064] In some possible embodiments, the power distribution unit can be a power source independent of the large impeller, such as a drive motor, with the output shaft of the drive motor connected to the center of the small impeller assembly, thereby generating torque on the small impeller assembly, which causes the small impeller assembly to rotate about its center.

[0065] In some other possible embodiments, the power distribution component can be a common transmission component that transmits power from the large impeller to the small impeller assembly, causing the small impeller assembly to rotate around its center.

[0066] For example, the power distribution component is a drive wheel and belt respectively located at the bottom of the large impeller and the small impeller assembly, which are belt driven so that the torque generated by the rotation of the large impeller is transmitted to the small impeller assembly through the belt, thereby causing the small impeller assembly to rotate around its center.

[0067] For example, the power distribution component is a worm gear, which is connected to a large impeller and a worm wheel is connected to a small impeller assembly. The teeth of the worm gear and the worm wheel are set at an angle, so that the rotation of the large impeller drives the worm gear to rotate. The worm gear generates torque on the worm wheel of the small impeller assembly, thus realizing the small impeller assembly to rotate around its center through worm gear and worm wheel transmission.

[0068] Therefore, while the power distribution component is preferably a gear ring with a gear structure, it can also be a power source and a common transmission component that are set up independently of the large impeller.

[0069] It is understandable that the central protrusion, extending beyond the upper surface of the large impeller, inherently functions to agitate the water flow and stir the clothes. The small impeller assembly, tilted onto this protrusion—either on the top or side of the protrusion—provides better assistance to the large impeller in rinsing and stirring the clothes compared to the more common horizontally positioned small impeller. Because the large impeller's agitation range is vertically upward, while the small impeller assembly's agitation range is tilted upward, their agitation ranges inevitably overlap. This allows the small impeller assembly to further disrupt the water flow generated by the large impeller, ensuring that clothes contacting and being agitated by the central protrusion fully contact the small impeller assembly. The impact force generated by the small impeller assembly acts more effectively on the clothes, preventing them from tangling on the large impeller and allowing the impact force to be more effectively used to remove dirt and stains, thus improving the washing effect.

[0070] It should be noted that during the rotation of the large pulsator, the small pulsator component not only revolves around the center of the large pulsator synchronously with the central protrusion, but also rotates around its own center. This makes the impact force generated by the small pulsator component much greater than the impact force when it is only rotating, thus achieving the best washing effect of the small pulsator component.

[0071] In this embodiment: the central protrusion extends from one end along the diameter direction of the large impeller 2; at least one side of the central protrusion extending in the direction of extension is inclined downward to form the mounting wall 24; preferably, the central protrusion extends from one end along the diameter direction of the large impeller 2 to the other end, and the one end and the other end are symmetrically arranged around the rotation center of the large impeller 2. This further enables the central protrusion to stir the clothes to the side where the small impeller assembly 3 is located, so that the small impeller assembly 3 can better cooperate with the large impeller 2, and the clothes can be more thoroughly rinsed and stirred.

[0072] Specifically, the central protrusion is more preferably as follows: Figure 3 , 5As shown in Figure 6, the small impeller assembly 3 extends from one end near the edge of the upper surface of the large impeller 2 along the diameter direction of the large impeller 2 to the other end of the upper surface edge. The one end and the other end are symmetrically arranged along the rotation center of the large impeller 2, so that both small impeller assemblies 3 can improve the washing effect.

[0073] In some possible embodiments, the central protrusion is located on one side of the rotation center of the large impeller, or the central protrusion passes through the rotation center but does not pass through the upper surface edge of the large impeller. It is understood that the central protrusion has the function of agitating the water flow and stirring the clothes.

[0074] In this embodiment: the lower side of the centrally protruding mounting wall 24 has a mounting chamber 23; the power distribution component 4 is disposed within the mounting chamber 23; one end of the rotating shaft 322 of the small impeller assembly 3 passes through the mounting wall 24 and contacts the power distribution component 4. When the large impeller 2 rotates, the portion of the small impeller assembly 3 in contact with the power distribution component 4 receives a reaction torque, which causes the small impeller assembly 3 to rotate around the center of its rotating shaft 322. The power distribution component 4 is set up by making full use of the internal space of the central protrusion, and the power to rotate the large impeller 2 can be used to make the small impeller assembly 3 rotate through the power distribution component 4, thereby realizing the simultaneous rotation of the large impeller 2 and the small impeller assembly 3 by a single power source.

[0075] Specifically, such as Figure 2 As shown, when the large impeller 2 is installed in the inner tub 1, the top wall of the central protrusion is close to the water passage hole on the side wall of the inner tub 1. That is, the central protrusion has a high height and occupies a large space inside the inner tub 1. At this time, by making the wall of the central protrusion relatively thin, an installation chamber 23 is formed. The installation chamber 23 is also equipped with an impeller shaft 22 that drives the large impeller 2 to rotate. This can make full use of the space inside the inner tub 1 occupied by the central protrusion, making the overall setup of the washing equipment more compact.

[0076] In this embodiment: one end of the shaft 322 of the small impeller assembly 3 has a first gear structure 321; the power distribution component 4 has a second gear structure 41 arranged circumferentially around the impeller shaft 22 of the large impeller 2; the first gear structure 321 meshes with the second gear structure 41, and when the large impeller 2 rotates, the small impeller assembly 3 revolves around the second gear structure 41, and the first gear structure 321 receives a reaction torque from the second gear structure 41, which causes the small impeller assembly 3 to rotate. Through the first gear structure 321 and the second gear structure 41, a stable reaction torque is ensured for the small impeller assembly 3, thereby achieving stable rotation of the small impeller assembly 3.

[0077] In this embodiment, the power distribution component 4 has a sleeve structure sleeved on the outside of the impeller shaft 22 of the large impeller 2, and the second gear structure 41 is formed at the upper end of the sleeve structure. The sleeve structure ensures that the power distribution component 4 has good structural strength, so that the power distribution component 4 can remain stable when the second gear structure 41 generates a reaction torque on the first gear structure 321.

[0078] In some possible embodiments, the power distribution component can also be a frustum structure or the like, and can also have good structural strength.

[0079] Specifically, such as Figure 4 As shown, the power distribution component 4 is arranged from bottom to top as follows: a fixing plate 43, a bracket 42, and a second gear structure 41. The fixing plate 43 has an upper surface area slightly larger than the projected area of ​​the second gear structure 41. The fixing plate 43 has threaded holes through which screws or bolts pass to stably fix the fixing plate 43 to the bottom wall of the inner barrel 1. Preferably, four threaded holes are symmetrically arranged along the center of the power distribution component 4. The bracket 42 is preferably arranged with six evenly spaced brackets, which ensures the structural strength of the power distribution component 4 while reducing its weight and the amount of material used.

[0080] In this embodiment: the teeth of the second gear structure 41 are inclined downwards from its inner ring to its outer ring, and the teeth of the first gear structure 321 are inclined to mesh with the teeth of the second gear structure 41; the tooth profile angle of the first gear structure 321 is smaller than the tooth profile angle of the second gear structure 41. By the inclined meshing of the teeth of the second gear structure 41 with the first gear structure 321, and the smaller tooth profile angle of the first gear structure 321 than that of the second gear structure 41, the overall axial direction of the small impeller assembly 3 is further realized, allowing it to be inclined at a certain angle to the axial direction of the power distribution component 4.

[0081] It should be noted that the tooth profile angle is the conventional understanding, that is, the angle between the tooth surface of the gear structure and the axis of the gear structure.

[0082] Specifically, the small impeller assembly 3 includes a small impeller disk 31 and a bevel gear. The bevel gear passes through the side wall of the mounting chamber 23 and is fixedly assembled with the small impeller disk 31 mounted on the mounting wall 24. The rotating shaft 322 and the first gear structure 321 of the small impeller assembly 3 are both set on the bevel gear, thereby achieving a lower production cost for the small impeller assembly 3.

[0083] More specifically, such as Figure 3 and 4 As shown, the tooth profile of the first gear structure 321 and the second gear structure 41 is preferably straight, and the bevel gear is a straight bevel gear 32, thereby achieving stable meshing.

[0084] It is understood that the bevel gear can be replaced with any common gear component, such as a helical gear, spiral bevel gear, etc. Therefore, various common gear structures fall within the scope of the first gear structure and the second gear structure of this embodiment.

[0085] In this embodiment: the central protrusion has two mounting walls 24 that are radially symmetrical along the large impeller 2; at least two small impeller assemblies 3 are symmetrically arranged along the rotation center of the large impeller 2. This arrangement of multiple small impeller assemblies 3 effectively assists the large impeller 2 in rinsing and agitating clothes, thereby further enhancing the washing effect of the washing equipment.

[0086] Specifically, such as Figure 6 As shown, two sets of the small impeller assembly 3 are symmetrically arranged along the length direction of the central protrusion.

[0087] In this embodiment, as Figures 1 to 7 As shown, the specific structure of the large impeller 2 is as follows: the central protrusion of the large impeller 2 is an arc-shaped structure that gradually decreases from its center to both sides. The two sides along the length of the central protrusion are semi-circular mounting walls 24. The highest point of the mounting walls 24 is close to the highest point of the arc-shaped structure. The mounting walls 24 have circular mounting grooves that match the small impeller disc 31. (See also...) Figure 1 The large impeller 2 has an impeller cover 21 at its center. The impeller shaft 22 is hollow inside, and the impeller cover 21 is located at the top of the impeller shaft 22, sealing the hollow part inside the impeller shaft 22. The upper surface of the large impeller 2 also has a centrally protruding disc 25. The disc 25 has two grooves 252 symmetrically arranged along the length of the central protrusion. Each groove 252 has three through holes 251 to facilitate drainage and debris removal from the upper surface of the large impeller 2. The disc 25 also has two protrusions 253 symmetrically arranged along the length of the central protrusion. The protrusions 253 can assist the central protrusion in agitating clothes and water.

[0088] In this embodiment, as Figure 1 As shown, the specific assembly relationship when the large impeller 2 is installed on the bottom wall of the inner tub 1 is as follows: the disc body 25 of the large impeller 2 is spaced apart from the bottom wall of the inner tub 1, so that the spaced part is connected to the installation chamber 23. The output shaft of the reducer 5 of the washing equipment, as the power input shaft 51 of the impeller assembly, passes through the bottom wall of the inner tub 1 and is fixed to the center of the impeller shaft 22 by the nesting part 221, so that the reducer 5 can drive the large impeller 2 and the small impeller assembly 3 to rotate simultaneously.

[0089] In this embodiment, the small impeller assembly 3 effectively assists the large impeller 2 in rinsing and agitating clothes, thereby enhancing the washing effect of the washing equipment. By tilting at least one small impeller assembly 3 onto the central protruding mounting wall 24 of the large impeller 2, the power distribution component 4 causes the small impeller assembly 3 to rotate, resulting in stronger impact and agitation forces when the impeller of the washing equipment is running. The power for the rotation of the large impeller 2 can be achieved by rotating the small impeller assembly 3 through the power distribution component 4, thus enabling the large impeller 2 and the small impeller assembly 3 to rotate simultaneously through a single power source.

[0090] Example 2

[0091] like Figures 1 to 8 As shown, based on Embodiment 1, this embodiment also provides a washing device having a tub for holding clothes, the tub being, for example... Figure 1 The inner tub of the pulsator washing machine shown has a pulsator assembly as described in Embodiment 1 installed at the bottom of the tub.

[0092] It should be noted that, as Figures 1 to 8 The inner tub 1 of the conventional pulsator washing machine shown is only one example of the tub body described in this embodiment. The tub body can also be an unconventional tub body such as a non-perforated inner tub 1 that can independently hold washing water. Unconventional tub bodies will not affect the operation of the pulsator assembly.

[0093] In this embodiment, the power distribution component 4 of the impeller assembly is fixedly mounted on the bottom wall of the barrel. This achieves a mating installation between the impeller assembly and the bottom wall of the barrel.

[0094] In this embodiment: the large impeller has a through hole connecting the mounting chamber and the inside of the barrel; the bottom wall of the barrel has a chip removal hole connecting the mounting chamber and the outside of the barrel. Fluid inside the barrel flows through the through hole into the mounting chamber and is discharged to the outside of the barrel through the chip removal hole. The centrally protruding mounting chamber 23 can be used to house the power distribution component 4, as well as to discharge wire chips and water, achieving multiple uses from one chamber.

[0095] In some possible embodiments, such as Figure 3 As shown, the specific structure of the inner tub 1 for assembling the impeller assembly can be as follows: the inner tub 1 is provided with a guide rail or layered structure that cooperates with and limits the edge of the large impeller 2, so that the large impeller 2 will not move up and down when rotating. A limiting plate is also symmetrically provided at the bottom of the inner tub 1 along its center to ensure that the assembly between the large impeller 2 and the inner tub 1 will not loosen.

[0096] The bottom of the inner tub 1 is provided with an installation groove whose edge is close to its side wall. The large impeller 2 is provided on the installation groove, so that the large impeller 2 occupies a high proportion of the bottom of the inner tub 1, and can fully contact the clothes and water flow at the bottom of the inner tub 1.

[0097] At the center of the bottom of the inner barrel 1, an opening is provided for the output shaft of the reducer 5 to pass through. An annular structure is provided around the outer ring of the opening for fixing the fixing plate 43 of the power distribution component 4. Holes are provided on the annular structure for screws or bolts to pass through, ensuring stable assembly of the power distribution component 4. Multiple drainage grooves are evenly spaced around the annular structure, each containing a chip removal hole 121. Some drainage grooves also have reinforcing ribs. Furthermore, a filter with a filter cover 11 is provided on the side wall of the inner barrel 1.

[0098] Furthermore, the bottom sidewall of the inner tub 1 is provided with multiple protrusions at even intervals. During the rotation of the large impeller 2, the protrusions make it easier for the clothes to move towards the large impeller 2 and the small impeller assembly 3, thereby contacting and rubbing against them to achieve a better washing effect.

[0099] In this embodiment, at least one small impeller assembly 3 is inclinedly disposed on the centrally protruding mounting wall 24 of the large impeller 2, thereby generating stronger impact and agitation forces when the impeller operates. The power distribution component 4 causes the small impeller assembly 3 to rotate, effectively assisting the large impeller 2 in rinsing and agitating clothes, thus enhancing the washing effect of the washing equipment. The power for the rotation of the large impeller 2 can be achieved by the power distribution component 4, which in turn drives the small impeller assembly 3 to rotate, thus enabling a single power source to simultaneously drive the rotation of both the large impeller 2 and the small impeller assembly 3. The centrally protruding mounting chamber 23 can be used to house the power distribution component 4 and to discharge lint and water, achieving multiple uses from a single chamber.

[0100] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
